Market Insights

Dear Shareholder,

This annual report covers the 12-month reporting period ended June 30, 2023 (the “reporting period”). On the subsequent pages, you will find details regarding investment results and a discussion of certain factors that affected performance during the reporting period.

Amid elevated inflation in many countries during the reporting period, the global economy faced challenges from higher interest rates, tighter credit conditions stemming from the turmoil in the banking sector (especially in the United States (“U.S.”)), and geopolitical concerns. While the U.S. economy showed signs of resilience, some European economies experienced slower growth over the reporting period.

Continued central bank efforts to combat inflation

While inflation remained elevated over the reporting period, many central banks raised interest rates to rein in rising prices. The U.S. Federal Reserve (the “Fed”) raised the federal funds rate at 10 consecutive meetings, beginning in March 2022 through May 2023. In June 2023, the Fed then paused from raising rates in order to “assess additional information and its implications for monetary policy.” Meanwhile, the Bank of England and European Central Bank raised interest rates for the 13th and eighth consecutive time, respectively, as of June 2023. In contrast, the Bank of Japan maintained its accommodative monetary policy stance.

Mixed financial market returns

The yield on the benchmark 10-year U.S. Treasury rose over the reporting period, as did 10-year bond yields in most other developed market countries. The overall global credit bond market delivered positive total returns. Higher-rated global bonds underperformed lower-rated bonds. Global equities rallied, while commodity prices were volatile and produced mixed returns. The U.S. dollar weakened against the euro and the British pound, but appreciated against the Japanese yen.

Amid evolving conditions, we will continue to work diligently to navigate global markets and manage the assets that you have entrusted with us. We encourage you to speak with your financial advisor about your goals, and visit global.pimco.com for our latest insights.

Sincerely,

Deborah A. DeCotis	Eric D. Johnson
Chair of the Board of Trustees	President

Past performance is no guarantee of future results. Unless otherwise noted, index returns reflect the reinvestment of income distributions and capital gains, if any, but do not reflect fees, brokerage commissions or other expenses of investing. It is not possible to invest directly in an unmanaged index.

Statements concerning financial market trends are based on current market conditions, which will fluctuate. There is no guarantee that these investment strategies will work under all market conditions or are appropriate for all investors and each investor should evaluate their ability to invest for the long-term, especially during periods of downturn in the market. Outlook and strategies are subject to change without notice.

2 PIMCO CLOSED-END FUNDS

Important Information About the Funds

Information regarding each Fund’s principal investment strategies, principal risks and risk management strategies, the effects of each Fund’s leverage, and each Fund’s fundamental investment restrictions, including a summary of certain changes thereto during the most recent fiscal year, can be found within the relevant sections of this report. Please refer to the Table of Contents for further information.

We believe that bond funds have an important role to play in a well-diversified investment portfolio. It is important to note, however, that in an environment where interest rates may trend upward, rising rates would negatively impact the performance of most bond funds, and fixed-income securities and other instruments held by a Fund are likely to decrease in value. A wide variety of factors can cause interest rates or yields of U.S. Treasury securities (or yields of other types of bonds) to rise (e.g., central bank monetary policies, inflation rates, general economic conditions, etc.). In addition, changes in interest rates can be sudden and unpredictable, and there is no guarantee that Fund management will anticipate such movement accurately. A Fund may lose money as a result of movements in interest rates.

As of the date of this report, interest rates in the United States and many parts of the world, including certain European countries, continue to increase. In efforts to combat inflation, the U.S. Federal Reserve raised interest rates multiple times in 2022 and 2023. Thus, bond funds currently face a heightened level of risk associated with rising interest rates and/or bond yields. This could be driven by a variety of factors, including but not limited to central bank monetary policies, changing inflation or real growth rates, general economic conditions, increasing bond issuances or reduced market demand for low yielding investments. Further, while bond markets have steadily grown over the past three decades, dealer inventories of corporate bonds are near historic lows in relation to market size. As a result, there has been a significant reduction in the ability of dealers to “make markets”.

Bond funds and individual bonds with a longer duration (a measure used to determine the sensitivity of a security’s price to changes in interest rates) tend to be more sensitive to changes in interest rates, usually making them more volatile than securities or funds with shorter durations. All of the factors mentioned above, individually or collectively, could lead to increased volatility and/or lower liquidity in the fixed income markets or negatively impact a Fund’s performance or cause a Fund to incur losses.

A Fund may enter into opposite sides of multiple interest rate swaps or other derivatives with respect to the same underlying reference instrument (e.g., a 10-year U.S. treasury) that have different effective dates with respect to interest accrual time periods also for the principal purpose of generating distributable gains (characterized as ordinary income for tax purposes) that are not part of a Fund’s duration or yield

curve management strategies. In such a “paired swap transaction”, a Fund would generally enter into one or more interest rate swap agreements whereby a Fund agrees to make regular payments starting at the time the Fund enters into the agreements equal to a floating interest rate in return for payments equal to a fixed interest rate (the “initial leg”). A Fund would also enter into one or more interest rate swap agreements on the same underlying instrument, but take the opposite position (i.e., in this example, a Fund would make regular payments equal to a fixed interest rate in return for receiving payments equal to a floating interest rate) with respect to a contract whereby the payment obligations do not commence until a date following the commencement of the initial leg (the “forward leg”).

A Fund may engage in investment strategies, including those that employ the use of paired swaps transactions, the use of interest rate swaps to seek to capitalize on differences between short-term and long-term interest rates and other derivatives transactions, to, among other things, seek to generate current, distributable income, even if such strategies could potentially result in declines in the Fund’s net asset value (“NAV”). A Fund’s income and gain-generating strategies, including certain derivatives strategies, may generate current income and gains taxable as ordinary income sufficient to support monthly distributions even in situations when a Fund has experienced a decline in net assets due to, for example, adverse changes in the broad U.S. or non-U.S. equity markets or a Fund’s debt investments, or arising from its use of derivatives. For instance, a portion of a Fund’s monthly distributions may be sourced from paired swap transactions utilized to produce current distributable ordinary income for tax purposes on the initial leg, with a substantial possibility that a Fund will later realize a corresponding capital loss and potential decline in its NAV with respect to the forward leg (to the extent there are not corresponding offsetting capital gains being generated from other sources). Because some or all of these transactions may generate capital losses without corresponding offsetting capital gains, portions of a Fund’s distributions recognized as ordinary income for tax purposes (such as from paired swap transactions) may be economically similar to a taxable return of capital when considered together with such capital losses.

Classifications of the Funds’ portfolio holdings in this report are made according to financial reporting standards. The classification of a particular portfolio holding as shown in the Allocation Breakdown and Schedule of Investments sections of this report may differ from the classification used for the Funds’ compliance calculations, including those used in the Funds’ prospectus, investment objectives, regulatory, and other investment limitations and policies, which may be based on different asset class, sector or geographical classifications. Each Fund is separately monitored for compliance with respect to prospectus and regulatory requirements.

ANNUAL REPORT | JUNE 30, 2023 3

Important Information About the Funds (Cont.)

The geographical classification of foreign (non-U.S.) securities in this report, if any, are classified by the country of incorporation of a holding. In certain instances, a security’s country of incorporation may be different from its country of economic exposure.

In February 2022, Russia launched an invasion of Ukraine. As a result, Russia and other countries, persons and entities that have provided material aid to Russia’s aggression against Ukraine, have been the subject of economic sanctions and import and export controls imposed by countries throughout the world, including the United States. Such measures have had and may continue to have an adverse effect on the Russian, Belarusian and other securities and economies, which may, in turn, negatively impact a Fund. The extent, duration and impact of Russia’s military action in Ukraine, related sanctions and retaliatory actions are difficult to ascertain, but could be significant and have severe adverse effects on the region, including significant adverse effects on the regional, European, and global economies and the markets for certain securities and commodities, such as oil and natural gas, as well as other sectors. Further, a Fund may have investments in securities and instruments that are economically tied to the region and may have been negatively impacted by the sanctions and counter-sanctions by Russia, including declines in value and reductions in liquidity. The sanctions may cause a Fund to sell portfolio holdings at a disadvantageous time or price or to continue to hold investments that a Fund may no longer seek to hold. PIMCO will continue to actively manage these positions in the best interests of a Fund and its shareholders.

The Funds may invest in certain instruments that rely in some fashion upon the London Interbank Offered Rate (“LIBOR”). LIBOR was traditionally an average interest rate, determined by the ICE Benchmark Administration, that banks charge one another for the use of short-term money. In March 2021, the United Kingdom’s Financial Conduct Authority, which regulates LIBOR, announced plans to ultimately phase out the use of LIBOR. Although the transition process away from LIBOR for many instruments has been completed, some LIBOR use is continuing and there are potential effects related to the transition away from LIBOR or continued use of LIBOR on the Fund, or on certain instruments in which the Fund invests, which can be difficult to ascertain, and may vary depending on factors that include, but are not limited to: (i) existing fallback or termination provisions in individual contracts and (ii) whether, how, and when industry participants adopt new reference rates for affected instruments. The transition of investments from LIBOR to a replacement rate as a result of amendment, application of existing fallbacks, statutory requirements or otherwise may also result in a reduction in the value of certain instruments held by the Fund or a reduction in the effectiveness of related Fund transactions such as hedges. In addition, an instrument’s transition to a replacement rate could result in variations in the reported yields of the Fund that holds

such instrument. Any such effects of the transition away from LIBOR, as well as other unforeseen effects, could result in losses to the Fund.

The common shares of the Funds trade on the New York Stock Exchange. As with any stock, the price of a Fund’s common shares will fluctuate with market conditions and other factors. If you sell your common shares of a Fund, the price received may be more or less than your original investment. Shares of closed-end management investment companies, such as the Funds, frequently trade at a discount from their NAV and may trade at a price that is less than the initial offering price and/or the NAV of such shares. Further, if a Fund’s shares trade at a price that is more than the initial offering price and/or the NAV of such shares, including at a substantial premium and/or for an extended period of time, there is no assurance that any such premium will be sustained for any period of time and will not decrease, or that the shares will not trade at a discount to NAV thereafter.

U.S. and global markets recently have experienced increased volatility, including as a result of the recent failures of certain U.S. and non-U.S. banks, which could be harmful to the Funds and issuers in which they invest. For example, if a bank at which a Fund or issuer has an account fails, any cash or other assets in bank or custody accounts, which may be substantial in size, could be temporarily inaccessible or permanently lost by the Fund or issuer. If a bank that provides a subscription line credit facility, asset-based facility, other credit facility and/or other services to an issuer or to a fund fails, the issuer or fund could be unable to draw funds under its credit facilities or obtain replacement credit facilities or other services from other lending institutions with similar terms.

Issuers in which a Fund may invest can be affected by volatility in the banking sector. Even if banks used by issuers in which the Funds invest remain solvent, continued volatility in the banking sector could contribute to, cause or intensify an economic recession, increase the costs of capital and banking services or result in the issuers being unable to obtain or refinance indebtedness at all or on as favorable terms as could otherwise have been obtained. Conditions in the banking sector are evolving, and the scope of any potential impacts to the Funds and issuers, both from market conditions and also potential legislative or regulatory responses, are uncertain. Such conditions and responses, as well as a changing interest rate environment, can contribute to decreased market liquidity and erode the value of certain holdings, including those of U.S. and non-U.S. banks. Continued market volatility and uncertainty and/or a downturn in market and economic and financial conditions, as a result of developments in the banking sector or otherwise (including as a result of delayed access to cash or credit facilities), could have an adverse impact on the Funds and issuers in which they invest.

4 PIMCO CLOSED-END FUNDS

On each Fund Summary page in this Shareholder Report, the Average Annual Total Return table and Cumulative Returns chart measure performance assuming that any dividend and capital gain distributions were reinvested. Total return is calculated by determining the percentage change in NAV or market price (as applicable) in the specified period. Returns do not reflect the deduction of taxes that a shareholder would pay on Fund distributions. Total return for a period of more than one year represents the average annual total return. Performance at market price will differ from results at NAV. Although market price returns tend to reflect investment results over time, during shorter periods returns at market price can also be influenced by factors such as changing views about a Fund, market conditions, supply and demand for the Fund’s shares, or changes in the Fund’s dividends. Performance shown is net of fees and expenses. Historical NAV performance for a Fund may have been positively impacted by fee waivers or expense limitations in place during some or all of the periods shown, if applicable. Future performance (including total return or yield) and distributions may be negatively impacted by the expiration or reduction of any such fee waivers or expense limitations.

The dividend rate that a Fund pays on its common shares may vary as portfolio and market conditions change, and will depend on a number of factors, including without limit the amount of a Fund’s undistributed net investment income and net short- and long-term capital gains, as well as the costs of any leverage obtained by a Fund. As portfolio and market conditions change, the rate of distributions on the common shares and a Fund’s dividend policy could change. There can be no assurance that a change in market conditions or other factors will not result in a change in a Fund’s distribution rate or that the rate will be sustainable in the future.

The following table discloses the inception date and diversification status of each Fund:

Fund Name	Inception Date		Diversification Status
PIMCO Corporate & Income Opportunity Fund		12/27/02		Diversified
PIMCO Corporate & Income Strategy Fund		12/21/01		Diversified
PIMCO High Income Fund		04/30/03		Diversified
PIMCO Income Strategy Fund		08/29/03		Diversified
PIMCO Income Strategy Fund II		10/29/04		Diversified

An investment in a Fund is not a bank deposit and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. It is possible to lose money on investments in a Fund.

The Trustees are responsible generally for overseeing the management of the Funds. The Trustees authorize the Funds to enter into service agreements with Pacific Investment Management Company LLC

(“PIMCO”) and other service providers in order to provide, and in some cases authorize service providers to procure through other parties, necessary or desirable services on behalf of the Funds. Shareholders are not parties to or third-party beneficiaries of such service agreements. Neither a Fund’s prospectus or Statement of Additional Information (“SAI”), any press release or shareholder report, any contracts filed as exhibits to a Fund’s registration statement, nor any other communications, disclosure documents or regulatory filings (including this report) from or on behalf of a Fund creates a contract between or among any shareholders of a Fund, on the one hand, and the Fund, a service provider to the Fund, and/or the Trustees or officers of the Fund, on the other hand.

The Trustees (or the Funds and their officers, service providers or other delegates acting under authority of the Trustees) may amend its most recent prospectus or use a new prospectus or SAI with respect to a Fund, adopt and disclose new or amended policies and other changes in press releases and shareholder reports and/or amend, file and/or issue any other communications, disclosure documents or regulatory filings, and may amend or enter into any contracts to which a Fund is a party, and interpret the investment objective(s), policies, restrictions and contractual provisions applicable to any Fund, without shareholder input or approval, except in circumstances in which shareholder approval is specifically required by law (such as changes to fundamental investment policies) or where a shareholder approval requirement was specifically disclosed in a Fund’s then-current prospectus, SAI or shareholder report and is otherwise still in effect.

PIMCO has adopted written proxy voting policies and procedures (“Proxy Policy”) as required by Rule 206(4)-6 under the Investment Advisers Act of 1940, as amended. The Proxy Policy has been adopted by the Funds as the policies and procedures that PIMCO will use when voting proxies on behalf of the Funds. A description of the policies and procedures that PIMCO uses to vote proxies relating to portfolio securities of each Fund, and information about how each Fund voted proxies relating to portfolio securities held during the most recent twelve-month period ended June 30th, are available without charge, upon request, by calling the Funds at (844) 33-PIMCO, on the Funds’ website at www.pimco.com, and on the Securities and Exchange Commission’s (“SEC”) website at www.sec.gov.

The Funds file their complete schedules of portfolio holdings with the SEC for the first and third quarters of each fiscal year as an exhibit to their reports on Form N-PORT. The Funds’ Form N-PORT reports are available to the public on the SEC’s website at www.sec.gov and on PIMCO’s website at www.pimco.com, and upon request by calling PIMCO at (844) 33-PIMCO.

ANNUAL REPORT | JUNE 30, 2023 5

Important Information About the Funds (Cont.)

SEC rules allow shareholder reports to be delivered to investors by providing access to such reports online free of charge and by mailing a notice that the report is electronically available. Investors may elect to receive all reports in paper free of charge by contacting their financial intermediary or, if invested directly with a Fund, investors can inform the Fund by calling (844) 33-PIMCO. Any election to receive reports in paper will apply to all funds held with the fund complex if invested directly with a Fund or to all funds held in the investor’s account if invested through a financial intermediary, such as a broker-dealer or bank.

In April 2020, the SEC adopted amended rules modifying the registration, communications, and offering processes for registered closed-end funds and interval funds. Among other things, the amendments: (1) permit qualifying closed-end funds to use a short-form registration statement to offer securities in eligible transactions and certain funds to qualify as Well Known Seasoned Issuers; (2) permit interval funds to pay registration fees based on net issuance of shares in a manner similar to mutual funds; (3) require closed-end funds and interval funds to include additional disclosures in their annual reports; and (4) require certain information to be filed in interactive data format. The new rules had phased compliance, with the latest requirement taking effect as of February 1, 2023.

In October 2020, the SEC adopted a rule related to the use of derivatives, short sales, reverse repurchase agreements and certain other transactions by registered investment companies that rescinds and withdraws prior guidance of the SEC and its staff regarding asset segregation and cover transactions. Subject to certain exceptions, the rule requires funds that trade derivatives and other transactions that create future payment or delivery obligations to comply with a value-at-risk leverage limit and certain derivatives risk management program and reporting requirements. These requirements may limit the ability of the Funds to use derivatives and reverse repurchase agreements and similar financing transactions as part of their investment strategies and may increase the cost of the Funds’ investments and cost of doing business, which could adversely affect investors. The compliance date for the new rule and related reporting requirements was August 19, 2022.

In December 2020, the SEC adopted a rule addressing fair valuation of fund investments. The new rule sets forth requirements for good faith determinations of fair value as well as for the performance of fair value determinations, including related oversight and reporting obligations. The new rule also defines “readily available market quotations” for purposes of the definition of “value” under the Investment Company Act of 1940 (the “Act”), and the SEC noted that this definition will apply in all contexts under the Act. The effective date for the rule was March 8, 2021. The compliance date for the new rule and the related reporting requirements was September 8, 2022.

In May 2022, the SEC proposed amendments to a current rule governing fund naming conventions. In general, the current rule requires funds with certain types of names to adopt a policy to invest at least 80% of their assets in the type of investment suggested by the name. The proposed amendments would expand the scope of the current rule in a number of ways that would result in an expansion of the types of fund names that would require the fund to adopt an 80% investment policy under the rule. Additionally, the proposed amendments would modify the circumstances under which a fund may deviate from its 80% investment policy and address the use and valuation of derivatives instruments for purposes of the rule. The proposal’s impact on the Funds will not be known unless and until any final rulemaking is adopted.

In May 2022, the SEC proposed a framework that would require certain registered funds (such as the Funds) to disclose their environmental, social, and governance (“ESG”) investing practices. Among other things, the proposed requirements would mandate that funds meeting three pre-defined classifications (i.e., integrated, ESG focused and/or impact funds) provide prospectus and shareholder report disclosure related to the ESG factors, criteria and processes used in managing the fund. The proposal’s impact on the Funds will not be known unless and until any final rulemaking is adopted.

In October 2022, the SEC adopted changes to the mutual fund and exchange-traded fund (“ETF”) shareholder report and registration statement disclosure requirements and the registered fund advertising rules, which will impact the disclosures provided to shareholders. The rule amendments are effective as of January 24, 2023, but the SEC is providing an 18-month compliance period following the effective date for such amendments other than those addressing fee and expense information in advertisements that might be materially misleading.

In November 2022, the SEC adopted amendments to Form N-PX under the Act to improve the utility to investors of proxy voting information reported by mutual funds, ETFs and certain other funds. The rule amendments will expand the scope of funds’ Form N-PX reporting obligations, subject managers to Form N-PX reporting obligations for “Say on Pay” votes, enhance Form N-PX disclosures, permit joint reporting by funds, managers and affiliated managers on Form N-PX; and require website availability of fund proxy voting records. The amendments will become effective on July 1, 2024. Funds and managers will be required to file their first reports covering the period from July 1, 2023 to June 30, 2024 on amended Form N-PX by August 31, 2024.

In May 2023, the SEC adopted final amendments that will require increased disclosure regarding repurchases by issuers of their equity securities registered under Section 12 of the Securities Exchange Act of

6 PIMCO CLOSED-END FUNDS

1934, as amended. The final amendments apply to business development companies and listed closed-end funds, but they do not apply to open-end funds or unlisted closed-end funds. Business development companies and listed closed-end funds will be required to provide greater quantitative and qualitative details related to share repurchases in their periodic reports, including: (i) daily quantitative share repurchase data presented in a table attached as an exhibit to the issuer’s periodic reports; (ii) checkbox disclosure regarding whether its directors and officers purchased or sold shares that are the subject of the issuer’s repurchase plan or program within four business days before or after the issuer’s announcement of such repurchase plan or program or the announcement of an increase of an existing share repurchase plan or program; and (iii) narrative descriptions regarding the issuer’s repurchase programs and practices. Listed closed-end funds are required to comply with the new requirements beginning with the Form N-CSR that covers the first six-month period that begins on or after January 1, 2024.

(1)  Performance quoted represents past performance. Past performance is not a guarantee or a reliable indicator of future results. Current performance may be lower or higher than performance shown. Investment return and the principal value of an investment will fluctuate. Returns shown do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the sale of Fund shares. Total return, market price, NAV, market price distribution rate, and NAV distribution rate will fluctuate with changes in market conditions. The NAV presented may differ from the NAV reported for the same period in other Fund materials. Performance current to the most recent month-end is available at www.pimco.com or via (844) 33-PIMCO. Performance is calculated assuming all dividends and distributions are reinvested at prices obtained under the Fund’s dividend reinvestment plan. Performance does not reflect any brokerage commissions in connection with the purchase or sale of Fund shares.

Performance of an index is shown in light of a requirement by the Securities and Exchange Commission that the performance of an appropriate broad-based securities market index be disclosed. However, the Fund is not managed to an index nor should the index be viewed as a “benchmark” for the Fund’s performance. The index is not intended to be indicative of the Fund’s investment strategies, portfolio components or past or future performance. Please see Additional Information Regarding the Funds for a description of the Fund’s principal investment strategies.

(2)  Distribution rates are not performance and are calculated by annualizing the most recent distribution per share and dividing by the NAV or market price, as applicable, as of the reported date. Distributions may be comprised of ordinary income, net capital gains, and/or a return of capital (‘‘ROC’’) of your investment in the Fund. Because the distribution rate may include a ROC, it should not be confused with yield or income. If the Fund estimates that a portion of its distribution may be comprised of amounts from sources other than net investment income in accordance with its policies and good accounting practices, the Fund will notify shareholders of the estimated composition of such distribution through a Section 19 Notice. Please refer to the most recent Section 19 Notice, if applicable, for additional information regarding the estimated composition of distributions. Please visit www.pimco.com for most recent Section 19 Notice, if applicable. Final determination of a distribution’s tax character will be made on Form 1099 DIV sent to shareholders each January.

(3)  Represents total effective leverage outstanding, as a percentage of total managed assets. Total effective leverage consists of preferred shares, reverse repurchase agreements and other borrowings, credit default swap notional and floating rate notes issued in tender option bond transactions, as applicable (collectively “Total Effective Leverage”). The Fund may engage in other transactions not included in Total Effective Leverage disclosed above that may give rise to a form of leverage, including certain derivative transactions. For the purpose of calculating Total Effective Leverage outstanding as a percentage of total managed assets, total managed assets refer to total assets (including assets attributable to Total Effective Leverage that may be outstanding) minus accrued liabilities (other than liabilities representing Total Effective Leverage).

Market and Net Asset Value Information

The Fund’s common shares are listed on the NYSE under the trading or “ticker” symbol “PTY”. The Fund’s common shares commenced trading on the NYSE in December 2002. The conduct of any offering and the issuance of additional common shares pursuant to any offering may have an adverse effect on prices in the secondary market for the Fund’s common shares by increasing the number of shares available, which may put downward pressure on the market price for the common shares. The NAV of the Fund’s common shares will be reduced immediately following an offering by the sales load, commissions and offering expenses paid or reimbursed by the Fund in connection with such offering. The completion of an offering may result in an immediate dilution of the NAV per common share for all existing common shareholders.

The following table sets forth, for each of the periods indicated, the high and low closing market prices of the Fund’s common shares on the NYSE, the high and low NAV per common share and the high and low premium/discount to NAV per common share. See Note 3, Investment Valuation and Fair Value Measurements in the Notes to Financial Statements for information as to how the Fund’s NAV is determined.

ANNUAL REPORT | JUNE 30, 2023 9

The following information is presented in conformance with annual reporting requirements for funds that have filed a registration statement pursuant to General Instruction A.2 of Form N-2.

Summary of Fund Expenses

The following table is intended to assist investors in understanding the fees and expenses (annualized) that an investor in Common Shares of the Fund would bear, directly or indirectly, as a result of an offering. The table reflects the use of leverage attributable to the Fund’s outstanding Preferred Shares and reverse repurchase agreements averaged over the fiscal year ended June 30, 2023 in an amount equal to 32.34% of the Fund’s total average managed assets (including assets attributable to such leverage), and shows Fund expenses as a percentage of net assets attributable to Common Shares. The percentage above does not reflect the Fund’s use of other forms of economic leverage, such as credit default swaps or other derivative instruments. The table and example below are based on the Fund’s capital structure as of June 30, 2023. The extent of the Fund’s assets attributable to leverage following an offering, and the Fund’s associated expenses, are likely to vary (perhaps significantly) from these assumptions.

Shareholder Transaction Expense

Sales load (as a percentage of offering price)(1)	[    ]%
Offering Expenses Borne by Common Shareholders (as a percentage of offering price)(2)	[    ]%
Dividend Reinvestment Plan Fees(3)	None

1  In the event that the Common Shares to which this relates are sold to or through underwriters or dealer managers, a corresponding supplement will disclose the applicable sale load and/or commission.

2  The related supplement will disclose the estimated amount of offering expense, the offering price and the offering expenses borne by the Fund and indirectly by all of its Common Shareholders as a percentage of the offering price.

3  You will pay broker chargers if you direct your broker or the plan agent to sell your Common Shares that you acquired pursuant to a dividend reinvestment plan. You may also pay a pro rata share of brokerage commissions incurred in connection with open market purchase pursuant to the Fund’s Dividend Reinvestment Plan.

Annual Fund Operating Expenses

	Percentage of Net Assets Attributable to Common Shares (reflecting leverage attributable to ARPS and reverse repurchase agreements)
Management Fees(1)		0.74%
Dividend Cost on Preferred Shares(2)		1.47%
Interest Payments on Borrowed Funds(3)		1.45%
Other Expenses(4)		0.04%
Total Annual Fund Operating Expenses(5)		3.70%

1.  Management fees include fees payable to the Investment Manager for advisory services and for supervisory, administrative and other services. The Fund pays for the advisory, supervisory and administrative services it requires under what is essentially an all-in fee structure. Pursuant to an investment management agreement, PIMCO is paid a Management Fee of 0.65% of the Fund’s average daily net assets (including

daily net assets attributable to any preferred shares of the Fund that may be outstanding). The Fund (and not PIMCO) will be responsible for certain fees and expenses which are, reflected in the table above, that are not covered by the management fee under the investment management agreement. Please see Note 9, Fees and Expenses in the Notes to Financial Statements for an explanation of the management fee.

2.  Reflects the Fund’s outstanding Preferred Shares averaged over the fiscal year ended June 30, 2023, which represented 9.88% of the Fund’s total average managed assets (including the liquidation preference of outstanding Preferred Shares and assets attributable to reverse repurchase agreements), at an estimated annual dividend rate to the Fund of 10.14% (based on the weighted average Preferred Share dividend rate during the fiscal year ended June 30, 2023) and assumes the Fund will continue to pay Preferred Share dividends at the “maximum applicable rate” called for under the Fund’s Bylaws due to the ongoing failure of auctions for the ARPS. The actual dividend rate paid on the ARPS will vary over time in accordance with variations in market interest rates.

3.  Reflects the Fund’s use of leverage in the form of reverse repurchase agreements averaged over the fiscal year ended June 30, 2023, which represented 22.46% of the Fund’s total average managed assets (including assets attributable to reverse repurchase agreements), at an annual interest rate cost to the Fund of 3.55%, which is the weighted average interest rate cost during the fiscal year ended June 30, 2023. The actual amount of interest expense borne by the Fund will vary over time in accordance with the level of the Fund’s use of reverse repurchase agreements, dollar rolls and/or borrowings and variations in market interest rates. Borrowing expense is required to be treated as an expense of the Fund for accounting purposes. Any associated income or gains (or losses) realized from leverage obtained through such instruments is not reflected in the Annual Fund Operating Expenses table above, but would be reflected in the Fund’s performance results.

4.  Other expenses are estimated for the Fund’s fiscal year ending June 30, 2024.

5.  “Dividend Cost on Preferred Shares”, including distributions on Preferred Shares, and “Interest Payments on Borrowed Funds” are borne by the Fund separately from management fees paid to PIMCO. Excluding these expenses, Total Annual Fund Operating Expenses are 0.78%. Excluding only distributions on Preferred Shares of 1.47%, Total Annual Fund Operating Expenses are 2.23%.

Example

The following example illustrates the expenses that you would pay on a $1,000 investment in Common Shares of the Fund, assuming (1) that the Fund’s net assets do not increase or decrease, (2) that the Fund incurs total annual expenses of 3.70% of net assets attributable to Common Shares in years 1 through 10 (assuming assets attributable to Preferred Shares and reverse repurchase agreements representing 32.34% of the Fund’s total managed assets) and (3) a 5% annual return(1):

	1 Year		3 Years		5 Years		10 Years
Total Expenses Incurred	$	37	$	113	$	191	$	395

1  The example above should not be considered a representation of future expenses. Actual expenses may be higher or lower than those shown. The example assumes that the estimated Interest Payments on Borrowed Funds, Dividend Cost on Preferred Shares and Other Expenses set forth in the Annual Fund Operating Expenses table are accurate, that the rate listed under Total Annual Fund Operating Expenses remains the same each year and that all dividends and distributions are reinvested at NAV. Actual expenses may be greater or less than those assumed. Moreover, the Fund’s actual rate of return may be greater or less than the hypothetical 5% annual return shown in the example. The example does not include commissions or estimated offering expenses, which would cause the expenses shown in the example to increase.

Distributions may be comprised of ordinary income, net capital gains, and/or a return of capital (‘‘ROC’’) of your investment in the Fund. Because the distribution rate may include a ROC, it should not be confused with yield or income. If the Fund estimates that a portion of its distribution may be comprised of amounts from sources other than net investment income in accordance with its policies and good accounting practices, the Fund will notify shareholders of the estimated composition of such distribution through a Section 19 Notice. Please refer to the most recent Section 19 Notice, if applicable, for additional information regarding the estimated composition of distributions. Please visit www.pimco.com for most recent Section 19 Notice, if applicable. Final determination of a distribution’s tax character will be made on Form 1099 DIV sent to shareholders each January.

(3)  Represents total effective leverage outstanding, as a percentage of total managed assets. Total effective leverage consists of preferred shares, reverse repurchase agreements and other borrowings, credit default swap notional and floating rate notes issued in tender option bond transactions, as applicable (collectively “Total Effective Leverage”). The Fund may engage in other transactions not included in Total Effective Leverage disclosed above that may give rise to a form of leverage, including certain derivative transactions. For the purpose of calculating Total Effective Leverage outstanding as a percentage of total managed assets, total managed assets refer to total assets (including assets attributable to Total Effective Leverage that may be outstanding) minus accrued liabilities (other than liabilities representing Total Effective Leverage).

Market and Net Asset Value Information

The Fund’s common shares are listed on the NYSE under the trading or “ticker” symbol “PHK”. The Fund’s common shares commenced trading on the NYSE in April 2003. The conduct of any offering and the issuance of additional common shares pursuant to any offering may have an adverse effect on prices in the secondary market for the Fund’s common shares by increasing the number of shares available, which may put downward pressure on the market price for the common shares. The NAV of the Fund’s common shares will be reduced immediately following an offering by the sales load, commissions and offering expenses paid or reimbursed by the Fund in connection with such offering. The completion of an offering may result in an immediate dilution of the NAV per common share for all existing common shareholders.

The following table sets forth, for each of the periods indicated, the high and low closing market prices of the Fund’s common shares on the NYSE, the high and low NAV per common share and the high and low premium/discount to NAV per common share. See Note 3, Investment Valuation and Fair Value Measurements in the Notes to Financial Statements for information as to how the Fund’s NAV is determined.

ANNUAL REPORT | JUNE 30, 2023 15

The following information is presented in conformance with annual reporting requirements for funds that have filed a registration statement pursuant to General Instruction A.2 of Form N-2.

Summary of Fund Expenses

The following table is intended to assist investors in understanding the fees and expenses (annualized) that an investor in Common Shares of the Fund would bear, directly or indirectly, as a result of an offering. The table reflects the use of leverage attributable to the Fund’s outstanding Preferred Shares and reverse repurchase agreements averaged over the fiscal year ended June 30, 2023 in an amount equal to 25.24% of the Fund’s total average managed assets (including assets attributable to such leverage), and shows Fund expenses as a percentage of net assets attributable to Common Shares. The percentage above does not reflect the Fund’s use of other forms of economic leverage, such as credit default swaps or other derivative instruments. The table and example below are based on the Fund’s capital structure as of June 30, 2023. The extent of the Fund’s assets attributable to leverage following an offering, and the Fund’s associated expenses, are likely to vary (perhaps significantly) from these assumptions.

Shareholder Transaction Expense

Sales load (as a percentage of offering price)(1)	[ ]%
Offering Expenses Borne by Common Shareholders (as a percentage of offering price)(2)	[ ]%
Dividend Reinvestment Plan Fees(3)	None

1  In the event that the Common Shares to which this relates are sold to or through underwriters or dealer managers, a corresponding supplement will disclose the applicable sale load and/or commission.

2  The related supplement will disclose the estimated amount of offering expense, the offering price and the offering expenses borne by the Fund and indirectly by all of its Common Shareholders as a percentage of the offering price.

3  You will pay broker chargers if you direct your broker or the plan agent to sell your Common Shares that you acquired pursuant to a dividend reinvestment plan. You may also pay a pro rata share of brokerage commissions incurred in connection with open market purchase pursuant to the Fund’s Dividend Reinvestment Plan.

Annual Fund Operating Expenses

	Percentage of Net Assets Attributable to Common Shares (reflecting leverage attributable to ARPS and reverse repurchase agreements)
Management Fees(1)		0.83%
Dividend Cost on Preferred Shares(2)		0.71%
Interest Payments on Borrowed Funds(3)		1.78%
Other Expenses(4)		0.09%
Total Annual Fund Operating Expenses(5)		3.41%

1.  Management fees include fees payable to the Investment Manager for advisory services and for supervisory, administrative and other services. The Fund pays for the advisory, supervisory and administrative services it requires under what is essentially an all-in fee structure. Pursuant to an investment management agreement, PIMCO is paid a Management Fee of 0.76% of the Fund’s average daily net assets (including

daily net assets attributable to any preferred shares of the Fund that may be outstanding). The Fund (and not PIMCO) will be responsible for certain fees and expenses which are, reflected in the table above, that are not covered by the management fee under the investment management agreement. Please see Note 9, Fees and Expenses in the Notes to Financial Statements for an explanation of the management fee.

2.  Reflects the Fund’s outstanding Preferred Shares averaged over the fiscal year ended June 30, 2023, which represented 6.60% of the Fund’s total average managed assets (including the liquidation preference of outstanding Preferred Shares and assets attributable to reverse repurchase agreements), at an estimated annual dividend rate to the Fund of 8.11% (based on the weighted average Preferred Share dividend rate during the fiscal year ended June 30, 2023) and assumes the Fund will continue to pay Preferred Share dividends at the “maximum applicable rate” called for under the Fund’s Bylaws due to the ongoing failure of auctions for the ARPS. The actual dividend rate paid on the ARPS will vary over time in accordance with variations in market interest rates.

3.  Reflects the Fund’s use of leverage in the form of reverse repurchase agreements averaged over the fiscal year ended June 30, 2023, which represented 18.64% of the Fund’s total average managed assets (including assets attributable to reverse repurchase agreements), at an annual interest rate cost to the Fund of 3.44%, which is the weighted average interest rate cost during the fiscal year ended June 30, 2023. The actual amount of interest expense borne by the Fund will vary over time in accordance with the level of the Fund’s use of reverse repurchase agreements, dollar rolls and/or borrowings and variations in market interest rates. Borrowing expense is required to be treated as an expense of the Fund for accounting purposes. Any associated income or gains (or losses) realized from leverage obtained through such instruments is not reflected in the Annual Fund Operating Expenses table above, but would be reflected in the Fund’s performance results.

4.  Other expenses are estimated for the Fund’s fiscal year ending June 30, 2024.

5.  “Dividend Cost on Preferred Shares”, including distributions on Preferred Shares, and “Interest Payments on Borrowed Funds” are borne by the Fund separately from management fees paid to PIMCO. Excluding these expenses, Total Annual Fund Operating Expenses are 0.92%. Excluding only distributions on Preferred Shares of 0.71%, Total Annual Fund Operating Expenses are 2.70%.

Example

The following example illustrates the expenses that you would pay on a $1,000 investment in Common Shares of the Fund, assuming (1) that the Fund’s net assets do not increase or decrease, (2) that the Fund incurs total annual expenses of 3.41% of net assets attributable to Common Shares in years 1 through 10 (assuming assets attributable to Preferred Shares and reverse repurchase agreements representing 25.24% of the Fund’s total managed assets) and (3) a 5% annual return(1):

	1 Year		3 Years		5 Years		10 Years
Total Expenses Incurred	$	34	$	105	$	177	$	369

1  The example above should not be considered a representation of future expenses. Actual expenses may be higher or lower than those shown. The example assumes that the estimated Interest Payments on Borrowed Funds, Dividend Cost on Preferred Shares and Other Expenses set forth in the Annual Fund Operating Expenses table are accurate, that the rate listed under Total Annual Fund Operating Expenses remains the same each year and that all dividends and distributions are reinvested at NAV. Actual expenses may be greater or less than those assumed. Moreover, the Fund’s actual rate of return may be greater or less than the hypothetical 5% annual return shown in the example. The example does not include commissions or estimated offering expenses, which would cause the expenses shown in the example to increase.

Distributions may be comprised of ordinary income, net capital gains, and/or a return of capital (‘‘ROC’’) of your investment in the Fund. Because the distribution rate may include a ROC, it should not be confused with yield or income. If the Fund estimates that a portion of its distribution may be comprised of amounts from sources other than net investment income in accordance with its policies and good accounting practices, the Fund will notify shareholders of the estimated composition of such distribution through a Section 19 Notice. Please refer to the most recent Section 19 Notice, if applicable, for additional information regarding the estimated composition of distributions. Please visit www.pimco.com for most recent Section 19 Notice, if applicable. Final determination of a distribution’s tax character will be made on Form 1099 DIV sent to shareholders each January.

(3)  Represents total effective leverage outstanding, as a percentage of total managed assets. Total effective leverage consists of preferred shares, reverse repurchase agreements and other borrowings, credit default swap notional and floating rate notes issued in tender option bond transactions, as applicable (collectively “Total Effective Leverage”). The Fund may engage in other transactions not included in Total Effective Leverage disclosed above that may give rise to a form of leverage, including certain derivative transactions. For the purpose of calculating Total Effective Leverage outstanding as a percentage of total managed assets, total managed assets refer to total assets (including assets attributable to Total Effective Leverage that may be outstanding) minus accrued liabilities (other than liabilities representing Total Effective Leverage).

Fund Insights at NAV

The following affected performance (on a gross basis) during the reporting period:

» Exposure to holdings related to special situation investments, which may include companies undergoing stress, distress, challenges, or significant transition, contributed to absolute performance, as the securities posted positive returns.

» Exposure to emerging market debt contributed to absolute performance, as the sector posted positive performance.

» Exposure to high yield corporate credit contributed to absolute performance, as the sector posted positive performance.

» Exposure to holdings related to emerging market special situation investments, which may include companies undergoing stress, distress, challenges, or significant transition, detracted from absolute performance, as select securities posted negative returns.

» Interest rate positioning, most notably long exposure at the middle and long portion of the curve detracted from absolute performance, as rates rose.

» Exposure to bank capital detracted from absolute performance, as select securities posted negative returns.

Market and Net Asset Value Information

The Fund’s common shares are listed on the NYSE under the trading or “ticker” symbol “PFN”. The Fund’s common shares commenced trading on the NYSE in October 2004. The conduct of any offering and the issuance of additional common shares pursuant to any offering may have an adverse effect on prices in the secondary market for the Fund’s common shares by increasing the number of shares available, which may put downward pressure on the market price for the common shares. The NAV of the Fund’s common shares will be reduced immediately following an offering by the sales load, commissions and offering expenses paid or reimbursed by the Fund in connection with such offering. The completion of an offering may result in an immediate dilution of the NAV per common share for all existing common shareholders.

The following table sets forth, for each of the periods indicated, the high and low closing market prices of the Fund’s common shares on the NYSE, the high and low NAV per common share and the high and low premium/discount to NAV per common share. See Note 3, Investment Valuation and Fair Value Measurements in the Notes to Financial Statements for information as to how the Fund’s NAV is determined.

ANNUAL REPORT | JUNE 30, 2023 21

The following information is presented in conformance with annual reporting requirements for funds that have filed a registration statement pursuant to General Instruction A.2 of Form N-2.

Summary of Fund Expenses

The following table is intended to assist investors in understanding the fees and expenses (annualized) that an investor in Common Shares of the Fund would bear, directly or indirectly, as a result of an offering. The table reflects the use of leverage attributable to the Fund’s outstanding Preferred Shares and reverse repurchase agreements averaged over the fiscal year ended June 30, 2023 in an amount equal to 27.32% of the Fund’s total average managed assets (including assets attributable to such leverage), and shows Fund expenses as a percentage of net assets attributable to Common Shares. The percentage above does not reflect the Fund’s use of other forms of economic leverage, such as credit default swaps or other derivative instruments. The table and example below are based on the Fund’s capital structure as of June 30, 2023. The extent of the Fund’s assets attributable to leverage following an offering, and the Fund’s associated expenses, are likely to vary (perhaps significantly) from these assumptions.

Shareholder Transaction Expense

Sales load (as a percentage of offering price)(1)	[    ]%
Offering Expenses Borne by Common Shareholders (as a percentage of offering price)(2)	[    ]%
Dividend Reinvestment Plan Fees(3)	None

1  In the event that the Common Shares to which this relates are sold to or through underwriters or dealer managers, a corresponding supplement will disclose the applicable sale load and/or commission.

2  The related supplement will disclose the estimated amount of offering expense, the offering price and the offering expenses borne by the Fund and indirectly by all of its Common Shareholders as a percentage of the offering price.

3  You will pay broker chargers if you direct your broker or the plan agent to sell your Common Shares that you acquired pursuant to a dividend reinvestment plan. You may also pay a pro rata share of brokerage commissions incurred in connection with open market purchase pursuant to the Fund’s Dividend Reinvestment Plan.

Annual Fund Operating Expenses

	Percentage of Net Assets Attributable to Common Shares (reflecting leverage attributable to ARPS and reverse repurchase agreements)
Management Fees(1)		1.15%
Dividend Cost on Preferred Shares(2)		1.52%
Interest Payments on Borrowed Funds(3)		1.35%
Other Expenses(4)		0.07%
Total Annual Fund Operating Expenses(5)		4.09%

1.  Management fees include fees payable to the Investment Manager for advisory services and for supervisory, administrative and other services. The Fund pays for the advisory, supervisory and administrative services it requires under what is essentially an all-in fee structure. Pursuant to an investment management agreement, PIMCO is paid a Management Fee of 0.83% of the Fund’s average weekly total managed

assets. The Fund (and not PIMCO) will be responsible for certain fees and expenses which are, reflected in the table above, that are not covered by the management fee under the investment management agreement. Please see Note 9, Fees and Expenses in the Notes to Financial Statements for an explanation of the management fee.

2.  Reflects the Fund’s outstanding Preferred Shares averaged over the fiscal year ended June 30, 2023, which represented 10.91% of the Fund’s total average managed assets (including the liquidation preference of outstanding Preferred Shares and assets attributable to reverse repurchase agreements), at an estimated annual dividend rate to the Fund of 10.18% (based on the weighted average Preferred Share dividend rate during the fiscal year ended June 30, 2023) and assumes the Fund will continue to pay Preferred Share dividends at the “maximum applicable rate” called for under the Fund’s Bylaws due to the ongoing failure of auctions for the ARPS. The actual dividend rate paid on the ARPS will vary over time in accordance with variations in market interest rates.

3.  Reflects the Fund’s use of leverage in the form of reverse repurchase agreements averaged over the fiscal year ended June 30, 2023, which represented 16.41% of the Fund’s total average managed assets (including assets attributable to reverse repurchase agreements), at an annual interest rate cost to the Fund of 3.63%, which is the weighted average interest rate cost during the fiscal year ended June 30, 2023. The actual amount of interest expense borne by the Fund will vary over time in accordance with the level of the Fund’s use of reverse repurchase agreements, dollar rolls and/or borrowings and variations in market interest rates. Borrowing expense is required to be treated as an expense of the Fund for accounting purposes. Any associated income or gains (or losses) realized from leverage obtained through such instruments is not reflected in the Annual Fund Operating Expenses table above, but would be reflected in the Fund’s performance results.

4.  Other expenses are estimated for the Fund’s fiscal year ending June 30, 2024.

5.  “Dividend Cost on Preferred Shares”, including distributions on Preferred Shares, and “Interest Payments on Borrowed Funds” are borne by the Fund separately from management fees paid to PIMCO. Excluding these expenses, Total Annual Fund Operating Expenses are 1.22%. Excluding only distributions on Preferred Shares of 1.52%, Total Annual Fund Operating Expenses are 2.57%.

Example

The following example illustrates the expenses that you would pay on a $1,000 investment in Common Shares of the Fund, assuming (1) that the Fund’s net assets do not increase or decrease, (2) that the Fund incurs total annual expenses of 4.09% of net assets attributable to Common Shares in years 1 through 10 (assuming assets attributable to Preferred Shares and reverse repurchase agreements representing 27.32% of the Fund’s total managed assets) and (3) a 5% annual return(1):

	1 Year		3 Years		5 Years		10 Years
Total Expenses Incurred	$	41	$	124	$	209	$	428

1  The example above should not be considered a representation of future expenses. Actual expenses may be higher or lower than those shown. The example assumes that the estimated Interest Payments on Borrowed Funds, Dividend Cost on Preferred Shares and Other Expenses set forth in the Annual Fund Operating Expenses table are accurate, that the rate listed under Total Annual Fund Operating Expenses remains the same each year and that all dividends and distributions are reinvested at NAV. Actual expenses may be greater or less than those assumed. Moreover, the Fund’s actual rate of return may be greater or less than the hypothetical 5% annual return shown in the example. The example does not include commissions or estimated offering expenses, which would cause the expenses shown in the example to increase.

^ A zero balance may reflect actual amounts rounding to less than $0.01 or 0.01%.

+ Unaudited. Information is presented in conformance with annual reporting requirements for funds that have filed a registration statement pursuant to General Instruction A.2 of Form N-2 (“Short Form N-2”).

* Annualized, except for organizational expense, if any.

(a)  Includes adjustments required by U.S. GAAP and may differ from net asset values and performance reported elsewhere by the Funds.

(b)  Per share amounts based on average number of common shares outstanding during the year or period.

(c)  Auction Rate Preferred Shareholders (“ARPS”). See Note 14, Auction Rate Preferred Shares, in the Notes to Financial Statements for more information.

(d)  The tax characterization of distributions is determined in accordance with Federal income tax regulations. The actual tax characterization of distributions paid is determined at the end of the fiscal year. See Note 2, Distributions — Common Shares, in the Notes to Financial Statements for more information.

(e)  Total investment return is calculated assuming a purchase of a common share at the market price on the first day and a sale of a common share at the market price on the last day of each year or period reported. Dividends and distributions, if any, are assumed, for purposes of this calculation, to be reinvested at prices obtained under the Funds’ dividend reinvestment plan. Total investment return does not reflect brokerage commissions in connection with the purchase or sale of Fund shares.

(f)  Calculated on the basis of income and expenses applicable to both common and preferred shares relative to the average net assets of common shareholders. The expense ratio and net investment income do not reflect the effects of dividend payments to preferred shareholders.

(g) Ratio includes interest expense which primarily relates to participation in borrowing and financing transactions. See Note 5, Borrowings and Other Financing Transactions, in the Notes to Financial Statements for more information.

(h)  The NAV presented may differ from the NAV reported for the same period in other Fund materials.

(i)  Fiscal year end changed from July 31st to June 30th.

(j)  Total distributions for the period ended June 30, 2022 may be lower than prior fiscal years due to fiscal year end change resulting in a reduction of the amount of days in the period ended June 30, 2022.

(k) Fiscal year end changed from November 30th to July 31st.

(l) Total distributions for the period ended July 31, 2015 may be lower than prior fiscal years due to fiscal year end changes resulting in a reduction of the amount of days in the period ended July 31, 2015.

(m) Fiscal year end changed from October 31st to July 31st.

(n) Fiscal year end changed from March 31st to July 31st.

1 “Asset Coverage per Preferred Share” means the ratio that the value of the total assets of the Fund, less all liabilities and indebtedness not represented by ARPS, bears to the aggregate of the involuntary liquidation preference of ARPS, expressed as a dollar amount per ARPS.

2  “Involuntary Liquidating Preference“ means the amount to which a holder of ARPS would be entitled upon the involuntary liquidation of the Fund in preference to the Common Shareholders, expressed as a dollar amount per Preferred Share.

3  The ARPS have no readily ascertainable market value. Auctions for the ARPS have failed since February 2008, there is currently no active trading market for the ARPS and the Fund is not able to reliably estimate what their value would be in a third-party market sale. The liquidation value of the ARPS represents its liquidation preference, which approximates fair value of the shares less any accumulated unpaid dividends. See Note 14, Auction-Rate Preferred Shares, in the notes to Financial Statements for more information.

FINANCIAL DERIVATIVE INSTRUMENTS: EXCHANGE-TRADED OR CENTRALLY CLEARED SUMMARY

The following is a summary of the market value and variation margin of Exchange-Traded or Centrally Cleared Financial Derivative Instruments as of June 30, 2023:

	Financial Derivative Assets								Financial Derivative Liabilities
	Market Value		Variation Margin Asset				Total		Market Value		Variation Margin Liability				Total
	Purchased Options		Futures		Swap Agreements				Written Options		Futures		Swap Agreements
Total Exchange-Traded or Centrally Cleared	$	0	$	0	$	2,848	$	2,848	$	0	$	0	$	(2,854)	$	(2,854)

(l) Securities with an aggregate market value of $964 and cash of $48,999 have been pledged as collateral for exchange-traded and centrally cleared financial derivative instruments as of June 30, 2023. See Note 8, Master Netting Arrangements, in the Notes to Financial Statements for more information.

(1) If the Fund is a seller of protection and a credit event occurs, as defined under the terms of that particular swap agreement, the Fund will either (i) pay to the buyer of protection an amount equal to the notional amount of the swap and take delivery of the referenced obligation or underlying securities comprising the referenced index or (ii) pay a net settlement amount in the form of cash, securities or other deliverable obligations equal to the notional amount of the swap less the recovery value of the referenced obligation or underlying securities comprising the referenced index.

(2) Implied credit spreads, represented in absolute terms, utilized in determining the market value of credit default swap agreements on corporate or sovereign issues as of period end serve as indicators of the current status of the payment/performance risk and represent the likelihood or risk of default for the credit derivative. The implied credit spread of a particular referenced entity reflects the cost of buying/selling protection and may include upfront payments required to be made to enter into the agreement. Wider credit spreads represent a deterioration of the referenced entity’s credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the agreement.

(3) The maximum potential amount the Fund could be required to pay as a seller of credit protection or receive as a buyer of credit protection if a credit event occurs as defined under the terms of that particular swap agreement.

(4) The prices and resulting values for credit default swap agreements serve as indicators of the current status of the payment/performance risk and represent the likelihood of an expected liability (or profit) for the credit derivative should the notional amount of the swap agreement be closed/sold as of the period end. Increasing market values, in absolute terms when compared to the notional amount of the swap, represent a deterioration of the underlying referenced instrument’s credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the agreement.

(5) This instrument has a forward starting effective date. See Note 2, Securities Transactions and Investment Income, in the Notes to Financial Statements for further information.

(5) Net Exposure represents the net receivable/(payable) that would be due from/to the counterparty in the event of default. Exposure from OTC financial derivative instruments can only be netted across transactions governed under the same master agreement with the same legal entity. See Note 8, Master Netting Arrangements, in the Notes to Financial Statements for more information.

(1) If the Fund is a seller of protection and a credit event occurs, as defined under the terms of that particular swap agreement, the Fund will either (i) pay to the buyer of protection an amount equal to the notional amount of the swap and take delivery of the referenced obligation or underlying securities comprising the referenced index or (ii) pay a net settlement amount in the form of cash, securities or other deliverable obligations equal to the notional amount of the swap less the recovery value of the referenced obligation or underlying securities comprising the referenced index.

(2) Implied credit spreads, represented in absolute terms, utilized in determining the market value of credit default swap agreements on corporate issues as of period end serve as indicators of the current status of the payment/performance risk and represent the likelihood or risk of default for the credit derivative. The implied credit spread of a particular referenced entity reflects the cost of buying/selling protection and may include upfront payments required to be made to enter into the agreement. Wider credit spreads represent a deterioration of the referenced entity’s credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the agreement.

(3) The maximum potential amount the Fund could be required to pay as a seller of credit protection or receive as a buyer of credit protection if a credit event occurs as defined under the terms of that particular swap agreement.

(4) The prices and resulting values for credit default swap agreements serve as indicators of the current status of the payment/performance risk and represent the likelihood of an expected liability (or profit) for the credit derivative should the notional amount of the swap agreement be closed/sold as of the period end. Increasing market values, in absolute terms when compared to the notional amount of the swap, represent a deterioration of the underlying referenced instrument’s credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the agreement.

(5) This instrument has a forward starting effective date. See Note 2, Securities Transactions and Investment Income, in the Notes to Financial Statements for further information.

(m) Securities with an aggregate market value of $881 have been pledged as collateral for financial derivative instruments as governed by International Swaps and Derivatives Association, Inc. master agreements as of June 30, 2023.

(1) If the Fund is a seller of protection and a credit event occurs, as defined under the terms of that particular swap agreement, the Fund will either (i) pay to the buyer of protection an amount equal to the notional amount of the swap and take delivery of the referenced obligation or underlying securities comprising the referenced index or (ii) pay a net settlement amount in the form of cash, securities or other deliverable obligations equal to the notional amount of the swap less the recovery value of the referenced obligation or underlying securities comprising the referenced index.

(2) Implied credit spreads, represented in absolute terms, utilized in determining the market value of credit default swap agreements on corporate issues as of period end serve as indicators of the current status of the payment/performance risk and represent the likelihood or risk of default for the credit derivative. The implied credit spread of a particular referenced entity reflects the cost of buying/selling protection and may include upfront payments required to be made to enter into the agreement. Wider credit spreads represent a deterioration of the referenced entity’s credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the agreement.

(3) The maximum potential amount the Fund could be required to pay as a seller of credit protection or receive as a buyer of credit protection if a credit event occurs as defined under the terms of that particular swap agreement.

(4) The prices and resulting values for credit default swap agreements serve as indicators of the current status of the payment/performance risk and represent the likelihood of an expected liability (or profit) for the credit derivative should the notional amount of the swap agreement be closed/sold as of the period end. Increasing market values, in absolute terms when compared to the notional amount of the swap, represent a deterioration of the underlying referenced instrument’s credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the agreement.

(5) Net Exposure represents the net receivable/(payable) that would be due from/to the counterparty in the event of default. Exposure from OTC financial derivative instruments can only be netted across transactions governed under the same master agreement with the same legal entity. See Note 8, Master Netting Arrangements, in the Notes to Financial Statements for more information.

Cash of $17,068 has been pledged as collateral for exchange-traded and centrally cleared financial derivative instruments as of June 30, 2023. See Note 8, Master Netting Arrangements, in the Notes to Financial Statements for more information.

(1) If the Fund is a seller of protection and a credit event occurs, as defined under the terms of that particular swap agreement, the Fund will either (i) pay to the buyer of protection an amount equal to the notional amount of the swap and take delivery of the referenced obligation or underlying securities comprising the referenced index or (ii) pay a net settlement amount in the form of cash, securities or other deliverable obligations equal to the notional amount of the swap less the recovery value of the referenced obligation or underlying securities comprising the referenced index.

(2) Implied credit spreads, represented in absolute terms, utilized in determining the market value of credit default swap agreements on corporate issues as of period end serve as indicators of the current status of the payment/performance risk and represent the likelihood or risk of default for the credit derivative. The implied credit spread of a particular referenced entity reflects the cost of buying/selling protection and may include upfront payments required to be made to enter into the agreement. Wider credit spreads represent a deterioration of the referenced entity’s credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the agreement.

(3) The maximum potential amount the Fund could be required to pay as a seller of credit protection or receive as a buyer of credit protection if a credit event occurs as defined under the terms of that particular swap agreement.

(4) The prices and resulting values for credit default swap agreements serve as indicators of the current status of the payment/performance risk and represent the likelihood of an expected liability (or profit) for the credit derivative should the notional amount of the swap agreement be closed/sold as of the period end. Increasing market values, in absolute terms when compared to the notional amount of the swap, represent a deterioration of the underlying referenced instrument’s credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the agreement.

(5) This instrument has a forward starting effective date. See Note 2, Securities Transactions and Investment Income, in the Notes to Financial Statements for further information.

(m) Securities with an aggregate market value of $988 have been pledged as collateral for financial derivative instruments as governed by International Swaps and Derivatives Association, Inc. master agreements as of June 30, 2023.

(1) If the Fund is a seller of protection and a credit event occurs, as defined under the terms of that particular swap agreement, the Fund will either (i) pay to the buyer of protection an amount equal to the notional amount of the swap and take delivery of the referenced obligation or underlying securities comprising the referenced index or (ii) pay a net settlement amount in the form of cash, securities or other deliverable obligations equal to the notional amount of the swap less the recovery value of the referenced obligation or underlying securities comprising the referenced index.

(2) Implied credit spreads, represented in absolute terms, utilized in determining the market value of credit default swap agreements on corporate issues as of period end serve as indicators of the current status of the payment/performance risk and represent the likelihood or risk of default for the credit derivative. The implied credit spread of a particular referenced entity reflects the cost of buying/selling protection and may include upfront payments required to be made to enter into the agreement. Wider credit spreads represent a deterioration of the referenced entity’s credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the agreement.

(3) The maximum potential amount the Fund could be required to pay as a seller of credit protection or receive as a buyer of credit protection if a credit event occurs as defined under the terms of that particular swap agreement.

(4) The prices and resulting values for credit default swap agreements serve as indicators of the current status of the payment/performance risk and represent the likelihood of an expected liability (or profit) for the credit derivative should the notional amount of the swap agreement be closed/sold as of the period end. Increasing market values, in absolute terms when compared to the notional amount of the swap, represent a deterioration of the underlying referenced instrument’s credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the agreement.

(5) Net Exposure represents the net receivable/(payable) that would be due from/to the counterparty in the event of default. Exposure from OTC financial derivative instruments can only be netted across transactions governed under the same master agreement with the same legal entity. See Note 8, Master Netting Arrangements, in the Notes to Financial Statements for more information.

Cash of $11,545 has been pledged as collateral for exchange-traded and centrally cleared financial derivative instruments as of June 30, 2023. See Note 8, Master Netting Arrangements, in the Notes to Financial Statements for more information.

(1) If the Fund is a seller of protection and a credit event occurs, as defined under the terms of that particular swap agreement, the Fund will either (i) pay to the buyer of protection an amount equal to the notional amount of the swap and take delivery of the referenced obligation or underlying securities comprising the referenced index or (ii) pay a net settlement amount in the form of cash, securities or other deliverable obligations equal to the notional amount of the swap less the recovery value of the referenced obligation or underlying securities comprising the referenced index.

(2) Implied credit spreads, represented in absolute terms, utilized in determining the market value of credit default swap agreements on corporate issues as of period end serve as indicators of the current status of the payment/performance risk and represent the likelihood or risk of default for the credit derivative. The implied credit spread of a particular referenced entity reflects the cost of buying/selling protection and may include upfront payments required to be made to enter into the agreement. Wider credit spreads represent a deterioration of the referenced entity’s credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the agreement.

(3) The maximum potential amount the Fund could be required to pay as a seller of credit protection or receive as a buyer of credit protection if a credit event occurs as defined under the terms of that particular swap agreement.

(4) The prices and resulting values for credit default swap agreements serve as indicators of the current status of the payment/performance risk and represent the likelihood of an expected liability (or profit) for the credit derivative should the notional amount of the swap agreement be closed/sold as of the period end. Increasing market values, in absolute terms when compared to the notional amount of the swap, represent a deterioration of the underlying referenced instrument’s credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the agreement.

(5) This instrument has a forward starting effective date. See Note 2, Securities Transactions and Investment Income, in the Notes to Financial Statements for further information.

(m) Securities with an aggregate market value of $523 have been pledged as collateral for financial derivative instruments as governed by International Swaps and Derivatives Association, Inc. master agreements as of June 30, 2023.

(1) If the Fund is a seller of protection and a credit event occurs, as defined under the terms of that particular swap agreement, the Fund will either (i) pay to the buyer of protection an amount equal to the notional amount of the swap and take delivery of the referenced obligation or underlying securities comprising the referenced index or (ii) pay a net settlement amount in the form of cash, securities or other deliverable obligations equal to the notional amount of the swap less the recovery value of the referenced obligation or underlying securities comprising the referenced index.

(2) Implied credit spreads, represented in absolute terms, utilized in determining the market value of credit default swap agreements on corporate issues as of period end serve as indicators of the current status of the payment/performance risk and represent the likelihood or risk of default for the credit derivative. The implied credit spread of a particular referenced entity reflects the cost of buying/selling protection and may include upfront payments required to be made to enter into the agreement. Wider credit spreads represent a deterioration of the referenced entity’s credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the agreement.

(3) The maximum potential amount the Fund could be required to pay as a seller of credit protection or receive as a buyer of credit protection if a credit event occurs as defined under the terms of that particular swap agreement.

78 PIMCO CLOSED-END FUNDS See Accompanying Notes

June 30, 2023

(4) The prices and resulting values for credit default swap agreements serve as indicators of the current status of the payment/performance risk and represent the likelihood of an expected liability (or profit) for the credit derivative should the notional amount of the swap agreement be closed/sold as of the period end. Increasing market values, in absolute terms when compared to the notional amount of the swap, represent a deterioration of the underlying referenced instrument’s credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the agreement.

(5) Net Exposure represents the net receivable/(payable) that would be due from/to the counterparty in the event of default. Exposure from OTC financial derivative instruments can only be netted across transactions governed under the same master agreement with the same legal entity. See Note 8, Master Netting Arrangements, in the Notes to Financial Statements for more information.

June 30, 2023

Cash of $18,436 has been pledged as collateral for exchange-traded and centrally cleared financial derivative instruments as of June 30, 2023. See Note 8, Master Netting Arrangements, in the Notes to Financial Statements for more information.

(1) If the Fund is a seller of protection and a credit event occurs, as defined under the terms of that particular swap agreement, the Fund will either (i) pay to the buyer of protection an amount equal to the notional amount of the swap and take delivery of the referenced obligation or underlying securities comprising the referenced index or (ii) pay a net settlement amount in the form of cash, securities or other deliverable obligations equal to the notional amount of the swap less the recovery value of the referenced obligation or underlying securities comprising the referenced index.

(2) Implied credit spreads, represented in absolute terms, utilized in determining the market value of credit default swap agreements on corporate issues as of period end serve as indicators of the current status of the payment/performance risk and represent the likelihood or risk of default for the credit derivative. The implied credit spread of a particular referenced entity reflects the cost of buying/selling protection and may include upfront payments required to be made to enter into the agreement. Wider credit spreads represent a deterioration of the referenced entity’s credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the agreement.

(3) The maximum potential amount the Fund could be required to pay as a seller of credit protection or receive as a buyer of credit protection if a credit event occurs as defined under the terms of that particular swap agreement.

(4) The prices and resulting values for credit default swap agreements serve as indicators of the current status of the payment/performance risk and represent the likelihood of an expected liability (or profit) for the credit derivative should the notional amount of the swap agreement be closed/sold as of the period end. Increasing market values, in absolute terms when compared to the notional amount of the swap, represent a deterioration of the underlying referenced instrument’s credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the agreement.

(5) This instrument has a forward starting effective date. See Note 2, Securities Transactions and Investment Income, in the Notes to Financial Statements for further information.

(m) Securities with an aggregate market value of $1,237 have been pledged as collateral for financial derivative instruments as governed by International Swaps and Derivatives Association, Inc. master agreements as of June 30, 2023.

(1) If the Fund is a seller of protection and a credit event occurs, as defined under the terms of that particular swap agreement, the Fund will either (i) pay to the buyer of protection an amount equal to the notional amount of the swap and take delivery of the referenced obligation or underlying securities comprising the referenced index or (ii) pay a net settlement amount in the form of cash, securities or other deliverable obligations equal to the notional amount of the swap less the recovery value of the referenced obligation or underlying securities comprising the referenced index.

(2) Implied credit spreads, represented in absolute terms, utilized in determining the market value of credit default swap agreements on corporate issues as of period end serve as indicators of the current status of the payment/performance risk and represent the likelihood or risk of default for the credit derivative. The implied credit spread of a particular referenced entity reflects the cost of buying/selling protection and may include upfront payments required to be made to enter into the agreement. Wider credit spreads represent a deterioration of the referenced entity’s credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the agreement.

(3) The maximum potential amount the Fund could be required to pay as a seller of credit protection or receive as a buyer of credit protection if a credit event occurs as defined under the terms of that particular swap agreement.

(4) The prices and resulting values for credit default swap agreements serve as indicators of the current status of the payment/performance risk and represent the likelihood of an expected liability (or profit) for the credit derivative should the notional amount of the swap agreement be closed/sold as of the period end. Increasing market values, in absolute terms when compared to the notional amount of the swap, represent a deterioration of the underlying referenced instrument’s credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the agreement.

(5) Net Exposure represents the net receivable/(payable) that would be due from/to the counterparty in the event of default. Exposure from OTC financial derivative instruments can only be netted across transactions governed under the same master agreement with the same legal entity. See Note 8, Master Netting Arrangements, in the Notes to Financial Statements for more information.

Hereinafter, the Board of Trustees of the Funds shall be collectively referred to as the “Board.”

2. SIGNIFICANT ACCOUNTING POLICIES

The following is a summary of significant accounting policies consistently followed by each Fund in the preparation of its financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”). Each Fund is treated as an investment company under the reporting requirements of U.S. GAAP. The functional and reporting currency for the Funds is the U.S. dollar. The preparation of financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of increases and decreases in net assets from operations during the reporting period. Actual results could differ from those estimates.

(a) Securities Transactions and Investment Income  Securities transactions are recorded as of the trade date for financial reporting purposes. Securities purchased or sold on a when-issued or delayed-delivery basis may be settled beyond a standard settlement period for the security after the trade date. Realized gains (losses) from securities sold are recorded on the identified cost basis. Dividend income is recorded on the ex-dividend date, except certain dividends from foreign securities where the ex-dividend date may have passed, which are recorded as soon as a Fund is informed of the ex-dividend date. Interest income, adjusted for the accretion of discounts and amortization of premiums, is recorded on the accrual basis from settlement date, with the exception of securities with a forward starting

effective date, where interest income is recorded on the accrual basis from effective date. For convertible securities, premiums attributable to the conversion feature are not amortized. Estimated tax liabilities on certain foreign securities are recorded on an accrual basis and are reflected as components of interest income or net change in unrealized appreciation (depreciation) on investments on the Statements of Operations, as appropriate. Tax liabilities realized as a result of such security sales are reflected as a component of net realized gain (loss) on investments on the Statements of Operations. Paydown gains (losses) on mortgage-related and other asset-backed securities, if any, are recorded as components of interest income on the Statements of Operations. Income or short-term capital gain distributions received from registered investment companies, if any, are recorded as dividend income. Long-term capital gain distributions received from registered investment companies, if any, are recorded as realized gains.

Debt obligations may be placed on non-accrual status and related interest income may be reduced by ceasing current accruals and writing off interest receivable when the collection of all or a portion of interest has become doubtful based on consistently applied procedures. A debt obligation is removed from non-accrual status when the issuer resumes interest payments or when collectability of interest is probable.

(b) Foreign Currency Translation  The market values of foreign securities, currency holdings and other assets and liabilities denominated in foreign currencies are translated into U.S. dollars based on the current exchange rates each business day. Purchases and sales of securities and income and expense items denominated in foreign currencies, if any, are translated into U.S. dollars at the exchange rate in effect on the transaction date. The Funds do not separately report the effects of changes in foreign exchange rates from changes in market prices on securities held. Such changes are included in net realized gain (loss) and net change in unrealized appreciation (depreciation) from investments on the Statements of Operations. The Funds may invest in foreign currency-denominated securities and may engage in foreign currency transactions either on a spot (cash) basis at the rate prevailing in the currency exchange market at the time or through a forward foreign currency contract. Realized foreign exchange gains (losses) arising from sales of spot foreign currencies, currency gains (losses) realized between the trade and settlement dates on securities transactions and the difference between the recorded amounts of dividends, interest, and foreign withholding taxes and the U.S. dollar equivalent of the amounts actually received or paid are included in net realized gain (loss) on foreign currency transactions on the Statements of Operations. Net unrealized foreign exchange gains (losses) arising from changes in foreign exchange rates on foreign denominated assets and liabilities other than investments in securities held at the end of the reporting period are included in net change in

unrealized appreciation (depreciation) on foreign currency assets and liabilities on the Statements of Operations.

(c) Distributions — Common Shares  The following table shows the anticipated frequency of distributions from net investment income to common shareholders.

	Distribution Frequency
Fund Name	Declared		Distributed
PIMCO Corporate & Income Opportunity Fund		Monthly		Monthly
PIMCO Corporate & Income Strategy Fund		Monthly		Monthly
PIMCO High Income Fund		Monthly		Monthly
PIMCO Income Strategy Fund		Monthly		Monthly
PIMCO Income Strategy Fund II		Monthly		Monthly

Each Fund intends to distribute at least annually to its shareholders all or substantially all of its net tax-exempt interest and any investment company taxable income, and may distribute its net capital gain. A Fund may revise its distribution policy or postpone the payment of distributions at any time.

As of the end of the fiscal year, none of the Funds were in default on long-term debt or had any accumulated dividend in arrears.

A Fund may engage in investment strategies, including those that employ the use of derivatives, to, among other things, seek to generate current, distributable income without regard to possible declines in the Fund’s net asset value (“NAV”). A Fund’s income and gain generating strategies, including certain derivatives strategies, may generate current, distributable income, even if such strategies could potentially result in declines in the Fund’s NAV. A Fund’s income and gain generating strategies, including certain derivatives strategies, may generate current income and gains taxable as ordinary income sufficient to support monthly distributions even in situations when the Fund has experienced a decline in net assets due to, for example, adverse changes in the broad U.S. or non-U.S. equity markets or the Fund’s debt investments, or arising from its use of derivatives. A Fund may enter into opposite sides of interest rate swap and other derivatives for the principal purpose of generating distributable gains on the one side (characterized as ordinary income for tax purposes) that are not part of the Fund’s duration or yield curve management strategies, and with a substantial possibility that the Fund will experience a corresponding capital loss and decline in NAV with respect to the opposite side transaction (to the extent it does not have corresponding offsetting capital gains). Consequently, common shareholders may receive distributions and owe tax on amounts that are effectively a taxable return of the shareholder’s investment in the Fund at a time when their investment in a Fund has declined in value, which may be taxed at ordinary income rates. The tax treatment of certain derivatives in which a Fund invests may be unclear and thus

subject to recharacterization. Any recharacterization of payments made or received by a Fund pursuant to derivatives potentially could affect the amount, timing or character of Fund distributions. In addition, the tax treatment of such investment strategies may be changed by regulation or otherwise.

Income distributions and capital gain distributions are determined in accordance with income tax regulations which may differ from U.S. GAAP. Differences between tax regulations and U.S. GAAP may cause timing differences between income and capital gain recognition. Further, the character of investment income and capital gains may be different for certain transactions under the two methods of accounting. As a result, income distributions and capital gain distributions declared during a fiscal period may differ significantly from the net investment income (loss) and realized gains (losses) reported on each Fund’s annual financial statements presented under U.S. GAAP.

Separately, if a Fund determines or estimates, as applicable, that a portion of a distribution may be comprised of amounts from sources other than net investment income in accordance with its policies, accounting records (if applicable), and accounting practices, the Fund will notify shareholders of the estimated composition of such distribution through a Section 19 Notice. For these purposes, a Fund determines or estimates, as applicable, the source or sources from which a distribution is paid, to the close of the period as of which it is paid, in reference to its internal accounting records and related accounting practices. If, based on such accounting records and practices, it is determined or estimated, as applicable, that a particular distribution does not include capital gains or paid-in surplus or other capital sources, a Section 19 Notice generally would not be issued. It is important to note that differences exist between a Fund’s daily internal accounting records and practices, a Fund’s financial statements presented in accordance with U.S. GAAP, and recordkeeping practices under income tax regulations. For instance, a Fund’s internal accounting records and practices may take into account, among other factors, tax-related characteristics of certain sources of distributions that differ from treatment under U.S. GAAP. Examples of such differences may include, but are not limited to, for certain Funds, the treatment of periodic payments under interest rate swap contracts. Accordingly, among other consequences, it is possible that a Fund may not issue a Section 19 Notice in situations where a Fund’s financial statements prepared later and in accordance with U.S. GAAP and/or the final tax character of those distributions might later report that the sources of those distributions included capital gains and/or a return of capital. Please visit www.pimco.com for the most recent Section 19 Notice, if applicable, for additional information regarding the estimated composition of distributions. Final determination of a distribution’s tax character will be provided to shareholders when such information is available.

ANNUAL REPORT | JUNE 30, 2023 95

Notes to Financial Statements (Cont.)

Distributions classified as a tax basis return of capital at a Fund’s fiscal year end, if any, are reflected on the Statements of Changes in Net Assets and have been recorded to paid in capital on the Statements of Assets and Liabilities. In addition, other amounts have been reclassified between distributable earnings (accumulated loss) and paid in capital on the Statements of Assets and Liabilities to more appropriately conform U.S. GAAP to tax characterizations of distributions.

(d) New Accounting Pronouncements and Regulatory Updates   In March 2020, the Financial Accounting Standards Board (“FASB”) issued an Accounting Standards Update (“ASU”), ASU 2020-04, which provides optional guidance to ease the potential accounting burden associated with transitioning away from the London Interbank Offered Rate (“LIBOR”) and other reference rates that are expected to be discontinued. ASU 2020-04 is effective for certain reference rate-related contract modifications that occurred during the period March 12, 2020 through December 31, 2022. In March 2021, the administrator for LIBOR announced the extension of the publication of a majority of the USD LIBOR settings to June 30, 2023. In December 2022, FASB issued ASU 2022-06, which includes amendments to extend the duration of the LIBOR transition relief to December 31, 2024, after which entities will no longer be permitted to apply the reference rate reform relief. Management is continuously evaluating the potential effect a discontinuation of LIBOR could have on the Funds’ investments and has determined that it is unlikely the ASU’s adoption will have a material impact on the Funds’ financial statements.

In October 2020, the U.S. Securities and Exchange Commission (“SEC”) adopted a rule related to the use of derivatives, short sales, reverse repurchase agreements and certain other transactions by registered investment companies that rescinds and withdraws the guidance of the SEC and its staff regarding asset segregation and cover transactions. Subject to certain exceptions, the rule requires funds that trade derivatives and other transactions that create future payment or delivery obligations to comply with a value-at-risk leverage limit and certain derivatives risk management program and reporting requirements. The compliance date for the new rule and the related reporting requirements was August 19, 2022. Management has implemented changes in connection with the rule and has determined that there is no material impact to the Funds’ financial statements.

In December 2020, the SEC adopted a rule addressing fair valuation of fund investments. The new rule sets forth requirements for good faith determinations of fair value as well as for the performance of fair value determinations, including related oversight and reporting obligations. The new rule also defines “readily available market quotations” for purposes of the definition of “value” under the Act, and the SEC noted that this definition would apply in all contexts

under the Act. The effective date for the rule was March 8, 2021. The compliance date for the new rule and the related reporting requirements was September 8, 2022. Management has implemented changes in connection with the rule and has determined that there is no material impact to the Funds’ financial statements.

In June 2022, the FASB issued ASU 2022-03, Fair Value Measurement (Topic 820), which affects all entities that have investments in equity securities measured at fair value that are subject to a contractual sale restriction. The amendments in ASU 2022-03 clarify that a contractual restriction on the sale of an equity security is not considered part of the unit of account of the equity security and, therefore, is not considered in measuring the fair value. The amendments also require additional disclosures for equity securities subject to contractual sale restrictions that are measured at fair value in accordance with Topic 820. The effective date for the amendments in ASU 2022-03 is for fiscal years beginning after December 15, 2023 and interim periods within those fiscal years. At this time, management is evaluating the implications of these changes on the financial statements.

The SEC made a final ruling on February 15, 2023 to adopt proposed amendments to the Settlement Cycle Rule (Rule 15c6-1) and other related rules under the Securities Exchange Act of 1934, as amended, to shorten the standard settlement cycle for most broker-dealer transactions from two business days after the trade date (T+2) to one business days after the trade date (T+1). The effective date was May 5, 2023, and the compliance date for the amendments is May 28, 2024. At this time, management is evaluating the implications of these changes on the financial statements.

3. INVESTMENT VALUATION AND FAIR VALUE MEASUREMENTS

(a) Investment Valuation Policies  The NAV of a Fund’s shares, or each of their respective share classes as applicable, is determined by dividing the total value of portfolio investments and other assets attributable to the Funds or class, less any liabilities, as applicable, by the total number of shares outstanding.

On each day that the New York Stock Exchange (“NYSE”) is open, the Fund’s shares are ordinarily valued as of the close of regular trading (normally 4:00 p.m., Eastern time) (“NYSE Close”). Information that becomes known to the Funds or their agents after the time as of which NAV has been calculated on a particular day will not generally be used to retroactively adjust the price of a security or the NAV determined earlier that day. If regular trading on the NYSE closes earlier than scheduled, each Fund may calculate its NAV as of the earlier closing time or calculate its NAV as of the NYSE Close for that day. Each Fund generally does not calculate its NAV on days on which the NYSE is not open for business. If the NYSE is closed on a day it would normally be

96 PIMCO CLOSED-END FUNDS

June 30, 2023

open for business, each Fund may calculate its NAV as of the NYSE Close for such day or such other time that the Funds may determine.

For purposes of calculating NAV, portfolio securities and other assets for which market quotations are readily available are valued at market value. A market quotation is readily available only when that quotation is a quoted price (unadjusted) in active markets for identical investments that the Fund can access at the measurement date, provided that a quotation will not be readily available if it is not reliable. Market value is generally determined on the basis of official closing prices or the last reported sales prices. The Funds will normally use pricing data for domestic equity securities received shortly after the NYSE Close and do not normally take into account trading, clearances or settlements that take place after the NYSE Close. A foreign (non-U.S.) equity security traded on a foreign exchange or on more than one exchange is typically valued using pricing information from the exchange considered by PIMCO to be the primary exchange. If market value pricing is used, a foreign (non-U.S.) equity security will be valued as of the close of trading on the foreign exchange, or the NYSE Close, if the NYSE Close occurs before the end of trading on the foreign exchange.

Investments for which market quotations are not readily available are valued at fair value as determined in good faith pursuant to Rule 2a-5 under the Act. As a general principle, the fair value of a security or other asset is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Pursuant to Rule 2a-5, the Board has designated PIMCO as the valuation designee (“Valuation Designee”) for each Fund to perform the fair value determination relating to all Fund investments. PIMCO may carry out its designated responsibilities as Valuation Designee through various teams and committees. The Valuation Designee’s policies and procedures govern the Valuation Designee’s selection and application of methodologies for determining and calculating the fair value of Fund investments. The Valuation Designee may value Fund portfolio securities for which market quotations are not readily available and other Fund assets utilizing inputs from pricing services, quotation reporting systems, valuation agents and other third-party sources (together, “Pricing Sources”).

Domestic and foreign (non-U.S.) fixed income securities, non-exchange traded derivatives, and equity options are normally valued on the basis of quotes obtained from brokers and dealers or Pricing Sources using data reflecting the earlier closing of the principal markets for those securities. Prices obtained from Pricing Sources may be based on, among other things, information provided by market makers or estimates of market values obtained from yield data relating to investments or securities with similar characteristics. Certain fixed income securities purchased on a delayed-delivery basis are marked to

market daily until settlement at the forward settlement date. Exchange- traded options, except equity options, futures and options on futures are valued at the settlement price determined by the relevant exchange. Swap agreements are valued on the basis of bid quotes obtained from brokers and dealers or market-based prices supplied by Pricing Sources. With respect to any portion of a Fund’s assets that are invested in one or more open-end management investment companies (other than ETFs), the Fund’s NAV will be calculated based on the NAVs of such investments.

If a foreign (non-U.S.) equity security’s value has materially changed after the close of the security’s primary exchange or principal market but before the NYSE Close, the security may be valued at fair value. Foreign (non-U.S.) equity securities that do not trade when the NYSE is open are also valued at fair value. With respect to foreign (non-U.S.) equity securities, a Fund may determine the fair value of investments based on information provided by Pricing Sources, which may recommend fair value or adjustments with reference to other securities, indexes or assets. In considering whether fair valuation is required and in determining fair values, the Valuation Designee may, among other things, consider significant events (which may be considered to include changes in the value of U.S. securities or securities indexes) that occur after the close of the relevant market and before the NYSE Close. A Fund may utilize modeling tools provided by third-party vendors to determine fair values of foreign (non-U.S.) securities. For these purposes, unless otherwise determined by the Valuation Designee, any movement in the applicable reference index or instrument (“zero trigger”) between the earlier close of the applicable foreign market and the NYSE Close may be deemed to be a significant event, prompting the application of the pricing model (effectively resulting in daily fair valuations). Foreign exchanges may permit trading in foreign (non-U.S.) equity securities on days when a Fund is not open for business, which may result in a Fund’s portfolio investments being affected when shareholders are unable to buy or sell shares.

Whole loans may be fair valued using inputs that take into account borrower- or loan-level data (e.g., credit risk of the borrower) that is updated periodically throughout the life of each individual loan; any new borrower- or loan-level data received in written reports periodically by a Fund normally will be taken into account in calculating the NAV. A Fund’s whole loan investments, including those originated by a Fund or through an alternative lending platform, generally are fair valued in accordance with procedures approved by the Board.

Investments valued in currencies other than the U.S. dollar are converted to the U.S. dollar using exchange rates obtained from Pricing Sources. As a result, the value of such investments and in turn, the NAV of a Fund’s shares may be affected by changes in the value of currencies in relation to the U.S. dollar. The value of investments traded

ANNUAL REPORT | JUNE 30, 2023 97

Notes to Financial Statements (Cont.)

in markets outside the United States or denominated in currencies other than the U.S. dollar may be affected significantly on a day that a Fund is not open for business. As a result, to the extent that a Fund holds foreign (non-U.S.) investments, the value of those investments may change at times when shareholders are unable to buy or sell shares and the value of such investments will be reflected in the Fund’s next calculated NAV.

Fair valuation may require subjective determinations about the value of a security. While the Funds’ and Valuation Designee’s policies and procedures are intended to result in a calculation of a Fund’s NAV that fairly reflects security values as of the time of pricing, a Fund cannot ensure that fair values accurately reflect the price that a Fund could obtain for a security if it were to dispose of that security as of the time of pricing (for instance, in a forced or distressed sale). The prices used by a Fund may differ from the value that would be realized if the securities were sold.

(b) Fair Value Hierarchy  U.S. GAAP describes fair value as the price that a Fund would receive to sell an asset or pay to transfer a liability in an orderly transaction between market participants at the measurement date. It establishes a fair value hierarchy that prioritizes inputs to valuation methods and requires disclosure of the fair value hierarchy, separately for each major category of assets and liabilities, that segregates fair value measurements into levels (Level 1, 2 or 3). The inputs or methodology used for valuing securities are not necessarily an indication of the risks associated with investing in those securities. Levels 1, 2 and 3 of the fair value hierarchy are defined as follows:

∎  Level 1 — Quoted prices (unadjusted) in active markets or exchanges for identical assets and liabilities.

∎  Level 2 — Significant other observable inputs, which may include, but are not limited to, quoted prices for similar assets or liabilities in markets that are active, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the assets or liabilities (such as interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and default rates) or other market corroborated inputs.

∎  Level 3 — Significant unobservable inputs based on the best information available in the circumstances, to the extent observable inputs are not available, which may include assumptions made by the Valuation Designee that are used in determining the fair value of investments.

Assets or liabilities categorized as Level 2 or 3 as of period end have been transferred between Levels 2 and 3 since the prior period due to changes in the method utilized in valuing the investments. Transfers from Level 2 to Level 3 are a result of a change, in the normal course of business, from the use of methods used by Pricing Sources (Level 2) to

the use of a Broker Quote or valuation technique which utilizes significant unobservable inputs due to an absence of current or reliable market-based data (Level 3). Transfers from Level 3 to Level 2 are a result of the availability of current and reliable market-based data provided by Pricing Sources or other valuation techniques which utilize significant observable inputs. In accordance with the requirements of U.S. GAAP, the amounts of transfers into and out of Level 3, if material, are disclosed in the Notes to Schedule of Investments for each respective Fund.

For fair valuations using significant unobservable inputs, U.S. GAAP requires a reconciliation of the beginning to ending balances for reported fair values that presents changes attributable to realized gain (loss), unrealized appreciation (depreciation), purchases and sales, accrued discounts (premiums), and transfers into and out of the Level 3 category during the period. The end of period value is used for the transfers between Levels of a Fund’s assets and liabilities. Additionally, U.S. GAAP requires quantitative information regarding the significant unobservable inputs used in the determination of fair value of assets or liabilities categorized as Level 3 in the fair value hierarchy. In accordance with the requirements of U.S. GAAP, a fair value hierarchy, and if material, a Level 3 reconciliation and details of significant unobservable inputs, have been included in the Notes to Schedule of Investments for each respective Fund.

(c) Valuation Techniques and the Fair Value Hierarchy

Level 1, Level 2 and Level 3 trading assets and trading liabilities, at fair value  The valuation methods (or “techniques”) and significant inputs used in determining the fair values of portfolio securities or other assets and liabilities categorized as Level 1, Level 2 and Level 3 of the fair value hierarchy are as follows:

Common stocks, ETFs, exchange-traded notes and financial derivative instruments, such as futures contracts, rights and warrants, or options on futures that are traded on a national securities exchange, are stated at the last reported sale or settlement price on the day of valuation. To the extent these securities are actively traded and valuation adjustments are not applied, they are categorized as Level 1 of the fair value hierarchy.

Investments in registered open-end investment companies (other than ETFs) will be valued based upon the NAVs of such investments and are categorized as Level 1 of the fair value hierarchy. Investments in unregistered open-end investment companies will be calculated based upon the NAVs of such investments and are considered Level 1 provided that the NAVs are observable, calculated daily and are the value at which both purchases and sales will be conducted.

Fixed income securities including corporate, convertible and municipal bonds and notes, U.S. government agencies, U.S. treasury obligations,

98 PIMCO CLOSED-END FUNDS

June 30, 2023

sovereign issues, bank loans, convertible preferred securities and non-U.S. bonds are normally valued on the basis of quotes obtained from brokers and dealers or Pricing Sources that use broker-dealer quotations, reported trades or valuation estimates from their internal pricing models. The Pricing Sources’ internal models use inputs that are observable such as issuer details, interest rates, yield curves, prepayment speeds, credit risks/spreads, default rates and quoted prices for similar assets. Securities that use similar valuation techniques and inputs as described above are categorized as Level 2 of the fair value hierarchy.

Fixed income securities purchased on a delayed-delivery basis or as a repurchase commitment in a sale-buyback transaction are marked to market daily until settlement at the forward settlement date and are categorized as Level 2 of the fair value hierarchy.

Mortgage-related and asset-backed securities are usually issued as separate tranches, or classes, of securities within each deal. These securities are also normally valued by Pricing Sources that use broker-dealer quotations, reported trades or valuation estimates from their internal pricing models. The pricing models for these securities usually consider tranche-level attributes, current market data, estimated cash flows and market-based yield spreads for each tranche, and incorporate deal collateral performance, as available. Mortgage-related and asset-backed securities that use similar valuation techniques and inputs as described above are categorized as Level 2 of the fair value hierarchy.

Valuation adjustments may be applied to certain securities that are solely traded on a foreign exchange to account for the market movement between the close of the foreign market and the NYSE Close. These securities are valued using Pricing Sources that consider the correlation of the trading patterns of the foreign security to the intraday trading in the U.S. markets for investments. Securities using these valuation adjustments are categorized as Level 2 of the fair value hierarchy. Preferred securities and other equities traded on inactive markets or valued by reference to similar instruments are also categorized as Level 2 of the fair value hierarchy.

Valuation adjustments may be applied to certain exchange traded futures and options to account for market movement between the exchange settlement and the NYSE close. These securities are valued using quotes obtained from a quotation reporting system, established market makers or Pricing Sources. Financial derivatives using these valuation adjustments are categorized as Level 2 of the fair value hierarchy.

Equity exchange-traded options and over the counter financial derivative instruments, such as forward foreign currency contracts and options contracts derive their value from underlying asset prices, indices, reference rates, and other inputs or a combination of these factors. These contracts are normally valued on the basis of quotes

obtained from a quotation reporting system, established market makers or Pricing Sources (normally determined as of the NYSE Close). Depending on the product and the terms of the transaction, financial derivative instruments can be valued by Pricing Sources using a series of techniques, including simulation pricing models. The pricing models use inputs that are observed from actively quoted markets such as quoted prices, issuer details, indices, bid/ask spreads, interest rates, implied volatilities, yield curves, dividends and exchange rates. Financial derivative instruments that use similar valuation techniques and inputs as described above are categorized as Level 2 of the fair value hierarchy.

Centrally cleared swaps and over the counter swaps derive their value from underlying asset prices, indices, reference rates, and other inputs or a combination of these factors. They are valued using a broker-dealer bid quotation or on market-based prices provided by Pricing Sources (normally determined as of the NYSE Close). Centrally cleared swaps and over the counter swaps can be valued by Pricing Sources using a series of techniques, including simulation pricing models. The pricing models may use inputs that are observed from actively quoted markets such as the overnight index swap rate, LIBOR forward rate, interest rates, yield curves and credit spreads. These securities are categorized as Level 2 of the fair value hierarchy.

Proxy pricing procedures set the base price of a fixed income security and subsequently adjust the price proportionally to market value changes of a pre-determined security deemed to be comparable in duration, generally a U.S. Treasury or sovereign note based on country of issuance. The base price may be a broker-dealer quote, transaction price or an internal value as derived by analysis of market data. The base price of the security may be reset on a periodic basis based on the availability of market data and procedures approved by the Valuation Oversight Committee. Significant changes in the unobservable inputs of the proxy pricing process (the base price) would result in direct and proportional changes in the fair value of the security. These securities are categorized as Level 3 of the fair value hierarchy.

If third-party evaluated vendor pricing is not available or not deemed to be indicative of fair value, the Manager may elect to obtain Broker Quotes directly from the broker-dealer or passed through from a third-party vendor. In the event that fair value is based upon a single sourced Broker Quote, these securities are categorized as Level 3 of the fair value hierarchy. Broker Quotes are typically received from established market participants. Although independently received, the Manager does not have the transparency to view the underlying inputs which support the market quotation. Significant changes in the Broker Quote would have direct and proportional changes in the fair value of the security.

ANNUAL REPORT | JUNE 30, 2023 99

Notes to Financial Statements (Cont.)

Reference instrument valuation estimates fair value by utilizing the correlation of the security to one or more broad-based securities, market indices, and/or other financial instruments, whose pricing information is readily available. Unobservable inputs may include those used in algorithms based on percentage change in the reference instruments and/or weights of each reference instrument. Significant changes in the unobservable inputs would result in direct and proportional changes in the fair value of the security. These securities are categorized as Level 2 or Level 3 of the fair value hierarchy depending on the source or input of the reference instrument.

Expected recovery valuation estimates that the fair value of an existing asset can be recovered, net of any liability. Significant changes in the unobservable inputs would result in direct and proportional changes in the fair value of the security. These securities are categorized as Level 3 of the fair value hierarchy.

The Discounted Cash Flow model is based on future cash flows generated by the investment and may be normalized based on expected investment performance. Future cash flows are discounted to present value using an appropriate rate of return, typically calibrated to the initial transaction date and adjusted based on Capital Asset Pricing Model and/or other market-based inputs. Significant changes in the unobservable inputs would result in direct and proportional changes in the fair value of the security. These securities are categorized as Level 3 of the fair value hierarchy.

Securities may be valued based on purchase prices of privately negotiated transactions. Significant changes in the unobservable inputs would result in direct and proportional changes in the fair value of the security. These securities are categorized as Level 3 of the fair value hierarchy.

Market comparable valuation estimates fair value by applying a valuation multiple to a key performance metric of the company, which may include unobservable inputs such as earnings before interest, taxes, depreciation and amortization (“EBITDA”), PIMCO’s assumptions regarding comparable companies and non-public statements from the underlying company. Significant changes in the unobservable inputs would result in direct and proportional changes in the fair value of the security. These securities are categorized as Level 3 of the fair value hierarchy.

Securities that are smaller in size than institutional-sized or round lot positions of the particular security/instrument type may apply an adjustment factor to the daily vendor-provided price for the corresponding round lot position to arrive at a fair value for the applicable odd lot positions. The adjustment factor is determined by comparing the prices of internal trades with vendor prices, calculating the weighted average differences, and using that difference as an adjustment factor to vendor prices. These securities are categorized as Level 3 of the fair value hierarchy.

Short-term debt instruments (such as commercial paper) having a remaining maturity of 60 days or less may be valued at amortized cost, so long as the amortized cost value of such short-term debt instruments is approximately the same as the fair value of the instrument as determined without the use of amortized cost valuation. These securities are categorized as Level 2 or Level 3 of the fair value hierarchy depending on the source of the base price.

When a fair valuation method is applied by PIMCO that uses significant unobservable inputs, investments will be priced by a method that the Valuation Designee believes reflects fair value and are categorized as Level 3 of the fair value hierarchy.

4. SECURITIES AND OTHER INVESTMENTS

Investments in Securities

The Funds may utilize the investments and strategies described below to the extent permitted by each Fund’s respective investment policies.

Inflation-Indexed Bonds  are fixed income securities whose principal value is periodically adjusted by the rate of inflation. The interest rate on these bonds is generally fixed at issuance at a rate lower than typical bonds. Over the life of an inflation-indexed bond, however, interest will be paid based on a principal value which is adjusted for inflation. Any increase or decrease in the principal amount of an inflation-indexed bond will be included as interest income on the Statements of Operations, even though investors do not receive their principal until maturity. Repayment of the original bond principal upon maturity (as adjusted for inflation) is guaranteed in the case of U.S. Treasury Inflation-Protected Securities (“TIPS”). For bonds that do not provide a similar guarantee, the adjusted principal value of the bond repaid at maturity may be less than the original principal.

Loans and Other Indebtedness, Loan Participations and Assignments  are direct debt instruments which are interests in amounts owed to lenders or lending syndicates by corporate, governmental, or other borrowers. A Fund’s investments in loans may be in the form of direct investments, participations in loans or assignments of all or a portion of loans from third parties or exposure to investments in loans through investments in a mutual fund or other pooled investment vehicle. A loan is often administered by a bank or other financial institution (the “agent”) that acts as agent for all holders. The agent administers the terms of the loan, as specified in the loan agreement. A Fund may invest in multiple series or tranches of a loan, which may have varying terms and carry different associated risks. A Fund generally has no right to enforce compliance with the terms of the loan agreement with the borrower. As a result, a Fund may be subject to the credit risk of both the borrower and the agent that is selling the loan agreement.

In the event of the insolvency of the agent selling a participation, a Fund may be treated as a general creditor of the agent and may not benefit

100 PIMCO CLOSED-END FUNDS

from any set-off between the agent and the borrower. When a Fund purchases assignments from agents it acquires direct rights against the borrowers of the loans. These loans may include participations in bridge loans, which are loans taken out by borrowers for a short period (typically less than one year) pending arrangement of more permanent financing through, for example, the issuance of bonds, frequently high yield bonds issued for the purpose of acquisitions.

Investments in loans are generally subject to risks similar to those of investments in other types of debt obligations, including, among others, credit risk, interest rate risk, variable and floating rate securities risk, and risks associated with mortgage-related securities. In addition, in many cases loans are subject to the risks associated with below-investment grade securities. The Funds may be subject to heightened or additional risks and potential liabilities and costs by investing in mezzanine and other subordinated loans, including those arising under bankruptcy, fraudulent conveyance, equitable subordination, environmental and other laws and regulations, and risks and costs associated with debt servicing and taking foreclosure actions associated with the loans.

Additionally, because loans are not ordinarily registered with the SEC or any state securities commission or listed on any securities exchange, there is usually less publicly available information about such instruments. In addition, loans may not be considered “securities” for purposes of the anti-fraud provisions under the federal securities laws and, as a result, as a purchaser of these instruments, a Fund may not be entitled to the anti-fraud protections of the federal securities laws. In the course of investing in such instruments, a Fund may come into possession of material nonpublic information and, because of prohibitions on trading in securities of issuers while in possession of such information, the Fund may be unable to enter into a transaction in a publicly-traded security of that issuer when it would otherwise be advantageous for the Fund to do so. Alternatively, a Fund may choose not to receive material nonpublic information about an issuer of such loans, with the result that the Fund may have less information about such issuers than other investors who transact in such assets.

The types of loans and related investments in which the Funds may invest include, among others, senior loans, subordinated loans (including second lien loans, B-Notes and mezzanine loans), whole loans, commercial real estate and other commercial loans and structured loans. The Funds may acquire direct interests in loans through primary loan distributions and/or in private transactions. In the case of subordinated loans, there may be significant indebtedness ranking ahead of the borrower’s obligation to the holder of such a loan, including in the event of the borrower’s insolvency. Mezzanine loans are typically secured by a pledge of an equity interest in the mortgage borrower that owns the real estate rather than an interest in a mortgage.

Investments in loans may include unfunded loan commitments, which are contractual obligations for future funding. Unfunded loan commitments may include revolving credit facilities, which may obligate a Fund to supply additional cash to the borrower on demand. Unfunded loan commitments represent a future obligation in full, even though a percentage of the committed amount may not be utilized by the borrower. When investing in a loan participation, a Fund has the right to receive payments of principal, interest and any fees to which it is entitled only from the agent selling the loan agreement and only upon receipt of payments by the agent from the borrower. Because investing in unfunded loan commitments creates a future obligation for a Fund to provide funding to a borrower upon demand in exchange for a fee, the Fund will segregate or earmark liquid assets with the Fund’s custodian in amounts sufficient to satisfy any such future obligations. A Fund may receive a commitment fee based on the undrawn portion of the underlying line of credit portion of a loan. In certain circumstances, a Fund may receive a penalty fee upon the prepayment of a loan by a borrower. Fees earned or paid are recorded as a component of interest income or interest expense, respectively, on the Statements of Operations. Unfunded loan commitments, if any, are reflected as a liability on the Statements of Assets and Liabilities.

Mortgage-Related and Other Asset-Backed Securities  directly or indirectly represent a participation in, or are secured by and payable from, loans on real property. Mortgage-related securities are created from pools of residential or commercial mortgage loans, including mortgage loans made by savings and loan institutions, mortgage bankers, commercial banks and others. These securities typically provide a monthly payment which consists of both principal and interest. Interest may be determined by fixed or adjustable rates. In times of declining interest rates, there is a greater likelihood that a Fund’s higher yielding securities will be pre-paid with the Fund being unable to reinvest the proceeds in an investment with as great a yield. The rate of prepayments on underlying mortgages will affect the price and volatility of a mortgage-related security, and may have the effect of shortening or extending the effective duration of the security relative to what was anticipated at the time of purchase. Interest-only and principal-only securities are especially sensitive to interest rate changes, which can affect not only their prices but can also change the income flows and repayment assumptions about those investments. The timely payment of principal and interest of certain mortgage-related securities is guaranteed with the full faith and credit of the U.S. Government. Pools created and guaranteed by non-governmental issuers, including government-sponsored corporations, may be supported by various forms of insurance or guarantees, but there can be no assurance that private insurers or guarantors can meet their obligations under the insurance policies or guarantee arrangements. Many of the risks of investing in mortgage-related securities secured by commercial mortgage loans reflect the effects of local and other economic conditions on real estate markets, the

Notes to Financial Statements (Cont.)

ability of tenants to make lease payments, and the ability of a property to attract and retain tenants. These securities may be less liquid and may exhibit greater price volatility than other types of mortgage-related or other asset-backed securities. Other asset-backed securities are created from many types of assets, including, but not limited to, auto loans, accounts receivable, such as credit card receivables and hospital account receivables, home equity loans, student loans, boat loans, mobile home loans, recreational vehicle loans, manufactured housing loans, aircraft leases, computer leases and syndicated bank loans. The Funds may invest in any level of the capital structure of an issuer of mortgage-backed or asset-backed securities, including the equity or “first loss” tranche.

Collateralized Debt Obligations  (“CDOs”) include Collateralized Bond Obligations (“CBOs”), Collateralized Loan Obligations (“CLOs”) and other similarly structured securities. CBOs and CLOs are types of asset-backed securities. A CBO is a trust which is typically backed by a diversified pool of high risk, below investment grade fixed income securities. A CLO is a trust typically collateralized by a pool of loans, which may include, among others, domestic and foreign senior secured loans, senior unsecured loans, and subordinate corporate loans, including loans that may be rated below investment grade or equivalent unrated loans. For both CBOs and CLOs, the cash flows from the trust are split into two or more portions, called tranches, varying in risk and yield. The riskiest portion is the “equity” tranche which bears the bulk of defaults from the bonds or loans in the trust and serves to protect the other, more senior tranches from default in all but the most severe circumstances. Since it is partially protected from defaults, a senior tranche from a CBO trust or CLO trust typically has higher ratings and lower yields than the underlying securities, and can be rated investment grade. Despite the protection from the equity tranche, CBO or CLO tranches can experience substantial losses due to actual defaults, increased sensitivity to defaults due to collateral default and disappearance of protecting tranches, market anticipation of defaults and aversion to CBO or CLO securities as a class. The risks of an investment in a CDO depend largely on the type of the collateral securities and the class of the CDO in which a Fund invests. CDOs carry additional risks including, but not limited to, (i) the possibility that distributions from collateral securities will not be adequate to make interest or other payments, (ii) the collateral may decline in value or default, (iii) the risk that a Fund may invest in CDOs that are subordinate to other classes, and (iv) the complex structure of the security may not be fully understood at the time of investment and may produce disputes with the issuer or unexpected investment results.

Collateralized Mortgage Obligations  (“CMOs”) are debt obligations of a legal entity that are collateralized by whole mortgage loans or private mortgage bonds and divided into classes. CMOs are structured into multiple classes, often referred to as “tranches,” with each class bearing a different stated maturity and entitled to a different schedule for payments of principal and interest, including prepayments. CMOs

may be less liquid and may exhibit greater price volatility than other types of mortgage-related or asset-backed securities.

As CMOs have evolved, some classes of CMO bonds have become more common. For example, a Fund may invest in parallel-pay and planned amortization class (“PAC”) CMOs and multi-class pass-through certificates. Parallel-pay CMOs and multi-class pass-through certificates are structured to provide payments of principal on each payment date to more than one class. These simultaneous payments are taken into account in calculating the stated maturity date or final distribution date of each class, which, as with other CMO and multi-class pass-through structures, must be retired by its stated maturity date or final distribution date but may be retired earlier. PACs generally require payments of a specified amount of principal on each payment date. PACs are parallel-pay CMOs with the required principal amount on such securities having the highest priority after interest has been paid to all classes. Any CMO or multi-class pass-through structure that includes PAC securities must also have support tranches — known as support bonds, companion bonds or non-PAC bonds — which lend or absorb principal cash flows to allow the PAC securities to maintain their stated maturities and final distribution dates within a range of actual prepayment experience. These support tranches are subject to a higher level of maturity risk compared to other mortgage-related securities, and usually provide a higher yield to compensate investors. If principal cash flows are received in amounts outside a pre-determined range such that the support bonds cannot lend or absorb sufficient cash flows to the PAC securities as intended, the PAC securities are subject to heightened maturity risk. A Fund may invest in various tranches of CMO bonds, including support bonds and equity or “first loss” tranches (see “Collateralized Debt Obligations” above).

Stripped Mortgage-Backed Securities  (“SMBS”) are derivative multi-class mortgage securities. SMBS are usually structured with two classes that receive different proportions of the interest and principal distributions on a pool of mortgage assets. An SMBS will have one class that will receive all of the interest (the interest-only or “IO” class), while the other class will receive the entire principal (the principal-only or “PO” class). IOs and POs can be extremely volatile in response to changes in interest rates. As interest rates rise and fall, the value of IOs tends to move in the same direction as interest rates. POs perform best when prepayments on the underlying mortgages rise since this increases the rate at which the principal is returned and the yield to maturity on the PO. When payments on mortgages underlying a PO are slower than anticipated, the life of the PO is lengthened and the yield to maturity is reduced. The yield to maturity on an IO class is extremely sensitive to the rate of principal payments (including prepayments) on the related underlying mortgage assets, and a rapid rate of principal payments may have a material adverse effect on a Fund’s yield to maturity from these securities. If the underlying mortgage assets experience greater than anticipated prepayments of principal, the

102 PIMCO CLOSED-END FUNDS

Funds may fail to recoup some or all of its initial investment in these securities even if the security is in one of the highest rating categories.

Payments received for IOs are included in interest income on the Statements of Operations. Because no principal will be received at the maturity of an IO, adjustments are made to the cost of the security on a monthly basis until maturity. These adjustments are included in interest income on the Statements of Operations. Payments received for POs are treated as reductions to the cost and par value of the securities.

Payment In-Kind Securities  may give the issuer the option at each interest payment date of making interest payments in either cash and/or additional debt securities. Those additional debt securities usually have the same terms, including maturity dates and interest rates, and associated risks as the original bonds. The daily market quotations of the original bonds may include the accrued interest (referred to as a dirty price) and require a pro rata adjustment from the unrealized appreciation (depreciation) on investments to interest receivable on the Statements of Assets and Liabilities.

Perpetual Bonds  are fixed income securities with no maturity date but pay a coupon in perpetuity (with no specified ending or maturity date). Unlike typical fixed income securities, there is no obligation for perpetual bonds to repay principal. The coupon payments, however, are mandatory. While perpetual bonds have no maturity date, they may have a callable date in which the perpetuity is eliminated and the issuer may return the principal received on the specified call date. Additionally, a perpetual bond may have additional features, such as interest rate increases at periodic dates or an increase as of a predetermined point in the future.

Real Estate Investment Trusts  (“REITs”) are pooled investment vehicles that own, and typically operate, income-producing real estate. If a REIT meets certain requirements, including distributing to shareholders substantially all of its taxable income (other than net capital gains), then it is not taxed on the income distributed to shareholders. Distributions received from REITs may be characterized as income, capital gain or a return of capital. A return of capital is recorded by a Fund as a reduction to the cost basis of its investment in the REIT. REITs are subject to management fees and other expenses, and so the Funds that invest in REITs will bear their proportionate share of the costs of the REITs’ operations.

Restricted Investments  are subject to legal or contractual restrictions on resale and may generally be sold privately, but may be required to be registered or exempted from such registration before being sold to the public. Private placement securities are generally considered to be restricted except for those securities traded between qualified institutional investors under the provisions of Rule 144A of the Securities Act of 1933. Disposal of restricted investments may involve time-consuming negotiations and expenses, and prompt sale at an

acceptable price may be difficult to achieve. Restricted investments held by the Funds as of June 30, 2023, as applicable, are disclosed in the Notes to Schedules of Investments.

Securities Issued by U.S. Government Agencies or Government-Sponsored Enterprises  are obligations of and, in certain cases, guaranteed by, the U.S. Government, its agencies or instrumentalities. Some U.S. Government securities, such as Treasury bills, notes and bonds, and securities guaranteed by the Government National Mortgage Association, are supported by the full faith and credit of the U.S. Government; others, such as those of the Federal Home Loan Banks, are supported by the right of the issuer to borrow from the U.S. Department of the Treasury (the “U.S. Treasury”); and others, such as those of the Federal National Mortgage Association (“FNMA” or “Fannie Mae”), are supported by the discretionary authority of the U.S. Government to purchase the agency’s obligations. U.S. Government securities may include zero coupon securities which do not distribute interest on a current basis and tend to be subject to a greater risk than interest-paying securities of similar maturities.

Government-related guarantors (i.e., not backed by the full faith and credit of the U.S. Government) include FNMA and the Federal Home Loan Mortgage Corporation (“FHLMC” or “Freddie Mac”). FNMA is a government-sponsored corporation. FNMA purchases conventional (i.e., not insured or guaranteed by any government agency) residential mortgages from a list of approved seller/servicers which include state and federally chartered savings and loan associations, mutual savings banks, commercial banks and credit unions and mortgage bankers. Pass-through securities issued by FNMA are guaranteed as to timely payment of principal and interest by FNMA, but are not backed by the full faith and credit of the U.S. Government. FHLMC issues Participation Certificates (“PCs”), which are pass-through securities, each representing an undivided interest in a pool of residential mortgages. FHLMC guarantees the timely payment of interest and ultimate collection of principal, but PCs are not backed by the full faith and credit of the U.S. Government. Instead, they are supported only by the discretionary authority of the U.S. Government to purchase the agency’s obligations.

In June 2019, FNMA and FHLMC started issuing Uniform Mortgage Backed Securities in place of their current offerings of TBA-eligible securities (the “Single Security Initiative”). The Single Security Initiative seeks to support the overall liquidity of the TBA market and aligns the characteristics of FNMA and FHLMC certificates. The long-term effects that the Single Security Initiative may have on the market for TBA and other mortgage-backed securities are uncertain.

Roll-timing strategies can be used where a Fund seeks to extend the expiration or maturity of a position, such as a TBA security on an underlying asset, by closing out the position before expiration and opening a new position with respect to substantially the same

ANNUAL REPORT | JUNE 30, 2023 103

Notes to Financial Statements (Cont.)

underlying asset with a later expiration date. TBA securities purchased or sold are reflected on the Statements of Assets and Liabilities as an asset or liability, respectively. Recently finalized FINRA rules include mandatory margin requirements for the TBA market that require the Funds to post collateral in connection with their TBA transactions. There is no similar requirement applicable to the Funds’ TBA counterparties. The required collateralization of TBA trades could increase the cost of TBA transactions to the Funds and impose added operational complexity.

Warrants  are securities that are usually issued together with a debt security or preferred security and that give the holder the right to buy a proportionate amount of common stock at a specified price. Warrants normally have a life that is measured in years and entitle the holder to buy common stock of a company at a price that is usually higher than the market price at the time the warrant is issued. Warrants may entail greater risks than certain other types of investments. Generally, warrants do not carry the right to receive dividends or exercise voting rights with respect to the underlying securities, and they do not represent any rights in the assets of the issuer. In addition, their value does not necessarily change with the value of the underlying securities, and they cease to have value if they are not exercised on or before their expiration date. If the market price of the underlying stock does not exceed the exercise price during the life of the warrant, the warrant will expire worthless. Warrants may increase the potential profit or loss to be realized from the investment as compared with investing the same amount in the underlying securities. Similarly, the percentage increase or decrease in the value of an equity security warrant may be greater than the percentage increase or decrease in the value of the underlying common stock. Warrants may relate to the purchase of equity or debt securities. Debt obligations with warrants attached to purchase equity securities have many characteristics of convertible securities and their prices may, to some degree, reflect the performance of the underlying stock. Debt obligations also may be issued with warrants attached to purchase additional debt securities at the same coupon rate. A decline in interest rates would permit a Fund to sell such warrants at a profit. If interest rates rise, these warrants would generally expire with no value.

5. BORROWINGS AND OTHER FINANCING TRANSACTIONS

The Funds may enter into the borrowings and other financing transactions described below to the extent permitted by each Fund’s respective investment policies.

The following disclosures contain information on a Fund’s ability to lend or borrow cash or securities to the extent permitted under the Act, which may be viewed as borrowing or financing transactions by a Fund. The location of these instruments in each Fund’s financial statements is described below.

(a) Repurchase Agreements  Under the terms of a typical repurchase agreement, a Fund purchases an underlying debt obligation (collateral) subject to an obligation of the seller to repurchase, and a Fund to resell, the obligation at an agreed-upon price and time. In an open maturity repurchase agreement, there is no pre-determined repurchase date and the agreement can be terminated by the Fund or counterparty at any time. The underlying securities for all repurchase agreements are held by a Fund’s custodian or designated subcustodians (in the case of tri-party repurchase agreements) and in certain instances will remain in custody with the counterparty. Traditionally, a Fund has used bilateral repurchase agreements wherein the underlying securities will be held by a Fund’s custodian. The market value of the collateral must be equal to or exceed the total amount of the repurchase obligations, including interest. Repurchase agreements, if any, including accrued interest, are included on the Statements of Assets and Liabilities. Interest earned is recorded as a component of interest income on the Statements of Operations. In periods of increased demand for collateral, a Fund may pay a fee for the receipt of collateral, which may result in interest expense to the Fund.

(b) Reverse Repurchase Agreements  In a reverse repurchase agreement, a Fund delivers a security in exchange for cash to a financial institution, the counterparty, with a simultaneous agreement to repurchase the same or substantially the same security at an agreed upon price and date. In an open maturity reverse repurchase agreement, there is no pre-determined repurchase date and the agreement can be terminated by a Fund or counterparty at any time. A Fund is entitled to receive principal and interest payments, if any, made on the security delivered to the counterparty during the term of the agreement. Cash received in exchange for securities delivered plus accrued interest payments to be made by a Fund to counterparties are reflected as a liability on the Statements of Assets and Liabilities. Interest payments made by a Fund to counterparties are recorded as a component of interest expense on the Statements of Operations. In periods of increased demand for the security, a Fund may receive a fee for use of the security by the counterparty, which may result in interest income to the Fund. In the event the buyer of securities under a reverse repurchase agreement files for bankruptcy or becomes insolvent, a Fund’s use of the proceeds of the agreement may be restricted pending a determination by the other party, or its trustee or receiver, whether to enforce a Fund’s obligation to repurchase the securities. Reverse repurchase agreements involve leverage risk and also the risk that the market value of the securities to be repurchased may decline below the repurchase price.

6. FINANCIAL DERIVATIVE INSTRUMENTS

The Funds may enter into the financial derivative instruments described below to the extent permitted by each Fund’s respective investment policies.

104 PIMCO CLOSED-END FUNDS

June 30, 2023

The following disclosures contain information on how and why the Funds use financial derivative instruments, and how financial derivative instruments affect the Funds’ financial position, results of operations and cash flows. The location and fair value amounts of these instruments on the Statements of Assets and Liabilities and the net realized gain (loss) and net change in unrealized appreciation (depreciation) on the Statements of Operations, each categorized by type of financial derivative contract and related risk exposure, are included in a table in the Notes to Schedules of Investments. The financial derivative instruments outstanding as of period end and the amounts of net realized gain (loss) and net change in unrealized appreciation (depreciation) on financial derivative instruments during the period, as disclosed in the Notes to Schedules of Investments, serve as indicators of the volume of financial derivative activity for the Funds.

PIMCO Corporate & Income Opportunity Fund is subject to regulation as a commodity pool under the Commodity Exchange Act by the Commodity Futures Trading Commission (the “CFTC”). The Manager has registered with the CFTC as a Commodity Pool Operator and a Commodity Trading Adviser with respect to the Fund, and is a member of the National Futures Association. As a result, additional CFTC-mandated disclosure, reporting and recordkeeping obligations apply to PIMCO Corporate & Income Opportunity Fund.

(a) Forward Foreign Currency Contracts  may be engaged, in connection with settling planned purchases or sales of securities, to hedge the currency exposure associated with some or all of a Fund’s securities or as part of an investment strategy. A forward foreign currency contract is an agreement between two parties to buy and sell a currency at a set price on a future date. The market value of a forward foreign currency contract fluctuates with changes in foreign currency exchange rates. Forward foreign currency contracts are marked to market daily, and the change in value is recorded by a Fund as an unrealized gain (loss). Realized gains (losses) are equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed and are recorded upon delivery or receipt of the currency. These contracts may involve market risk in excess of the unrealized gain (loss) reflected on the Statements of Assets and Liabilities. In addition, a Fund could be exposed to risk if the counterparties are unable to meet the terms of the contracts or if the value of the currency changes unfavorably to the U.S. dollar. To mitigate such risk, cash or securities may be exchanged as collateral pursuant to the terms of the underlying contracts.

(b) Swap Agreements  are bilaterally negotiated agreements between a Fund and a counterparty to exchange or swap investment cash flows, assets, foreign currencies or market-linked returns at specified, future intervals. Swap agreements may be privately negotiated in the over the counter market (“OTC swaps”) or may be cleared through a third party,

known as a central counterparty or derivatives clearing organization (“Centrally Cleared Swaps”). A Fund may enter into asset, credit default, cross-currency, interest rate, total return, variance and other forms of swap agreements to manage its exposure to credit, currency, interest rate, commodity, equity and inflation risk. In connection with these agreements, securities or cash may be identified as collateral or margin in accordance with the terms of the respective swap agreements to provide assets of value and recourse in the event of default or bankruptcy/insolvency.

Centrally Cleared Swaps are marked to market daily based upon valuations as determined from the underlying contract or in accordance with the requirements of the central counterparty or derivatives clearing organization. Changes in market value, if any, are reflected as a component of net change in unrealized appreciation (depreciation) on the Statements of Operations. Daily changes in valuation of centrally cleared swaps, if any, are disclosed within centrally cleared financial derivative instruments on the Statements of Assets and Liabilities. Centrally Cleared and OTC swap payments received or paid at the beginning of the measurement period are included on the Statements of Assets and Liabilities and represent premiums paid or received upon entering into the swap agreement to compensate for differences between the stated terms of the swap agreement and prevailing market conditions (credit spreads, currency exchange rates, interest rates, and other relevant factors). Upfront premiums received (paid) are initially recorded as liabilities (assets) and subsequently marked to market to reflect the current value of the swap. These upfront premiums are recorded as realized gain (loss) on the Statements of Operations upon termination or maturity of the swap. A liquidation payment received or made at the termination of the swap is recorded as realized gain (loss) on the Statements of Operations. Net periodic payments received or paid by a Fund are included as part of realized gain (loss) on the Statements of Operations.

For purposes of a Fund’s investment policy adopted pursuant to Rule 35d-1 under the Act (if any), the Fund will account for derivative instruments at market value. For purposes of applying a Fund’s other investment policies and restrictions, swap agreements, like other derivative instruments, may be valued by a Fund at market value, notional value or full exposure value. In the case of a credit default swap, in applying certain of a Fund’s investment policies and restrictions, the Funds will value the credit default swap at its notional value or its full exposure value (i.e., the sum of the notional amount for the contract plus the market value), but may value the credit default swap at market value for purposes of applying certain of a Fund’s other investment policies and restrictions. For example, a Fund may value credit default swaps at full exposure value for purposes of a Fund’s credit quality guidelines (if any) because such value in general better reflects a Fund’s actual economic exposure during the term of the credit

ANNUAL REPORT | JUNE 30, 2023 105

Notes to Financial Statements (Cont.)

default swap agreement. As a result, a Fund may, at times, have notional exposure to an asset class (before netting) that is greater or lesser than the stated limit or restriction noted in a Fund’s prospectus. In this context, both the notional amount and the market value may be positive or negative depending on whether a Fund is selling or buying protection through the credit default swap. The manner in which certain securities or other instruments are valued by a Fund for purposes of applying investment policies and restrictions may differ from the manner in which those investments are valued by other types of investors.

Entering into swap agreements involves, to varying degrees, elements of interest, credit, market and documentation risk in excess of the amounts recognized on the Statements of Assets and Liabilities. Such risks involve the possibility that there will be no liquid market for these agreements, that the counterparty to the agreements may fail to perform or meet an obligation or disagree as to the meaning of contractual terms in the agreements and that there may be unfavorable changes in interest rates or the values of the asset upon which the swap is based.

A Fund’s maximum risk of loss from counterparty credit risk is the discounted net value of the cash flows to be received from the counterparty over the contract’s remaining life, to the extent that amount is positive. The risk may be mitigated by having a master netting arrangement between a Fund and the counterparty and by the posting of collateral to a Fund to cover a Fund’s exposure to the counterparty.

To the extent a Fund has a policy to limit the net amount owed to or to be received from a single counterparty under existing swap agreements, such limitation only applies to counterparties to OTC swaps and does not apply to centrally cleared swaps where the counterparty is a central counterparty or derivatives clearing organization.

Credit Default Swap Agreements  on corporate, loan, sovereign, U.S. municipal or U.S. Treasury issues are entered into to provide a measure of protection against defaults of the issuers (i.e., to reduce risk where a Fund owns or has exposure to the referenced obligation) or to take an active long or short position with respect to the likelihood of a particular issuer’s default. Credit default swap agreements involve one party making a stream of payments (referred to as the buyer of protection) to another party (the seller of protection) in exchange for the right to receive a specified return in the event that the referenced entity, obligation or index, as specified in the swap agreement, undergoes a certain credit event. As a seller of protection on credit default swap agreements, a Fund will generally receive from the buyer of protection a fixed rate of income throughout the term of the swap provided that there is no credit event. As the seller, a Fund would effectively add leverage to its portfolio because, in addition to its total net assets, a Fund would be subject to investment exposure on the notional amount of the swap.

If a Fund is a seller of protection and a credit event occurs, as defined under the terms of that particular swap agreement, a Fund will either (i) pay to the buyer of protection an amount equal to the notional amount of the swap and take delivery of the referenced obligation or underlying securities comprising the referenced index or (ii) pay a net settlement amount in the form of cash, securities or other deliverable obligations equal to the notional amount of the swap less the recovery value of the referenced obligation or underlying securities comprising the referenced index. If a Fund is a buyer of protection and a credit event occurs, as defined under the terms of that particular swap agreement, a Fund will either (i) receive from the seller of protection an amount equal to the notional amount of the swap and deliver the referenced obligation, other deliverable obligations or underlying securities comprising the referenced index or (ii) receive a net settlement amount in the form of cash or securities equal to the notional amount of the swap less the recovery value of the referenced obligation or underlying securities comprising the referenced index. Recovery values are estimated by market makers considering either industry standard recovery rates or entity specific factors and considerations until a credit event occurs. If a credit event has occurred, the recovery value is determined by a facilitated auction whereby a minimum number of allowable broker bids, together with a specified valuation method, are used to calculate the settlement value. The ability to deliver other obligations may result in a cheapest-to-deliver option (the buyer of protection’s right to choose the deliverable obligation with the lowest value following a credit event).

Credit default swap agreements on corporate or sovereign issues involve one party making a stream of payments to another party in exchange for the right to receive a specified return in the event of a default or other credit event. If a credit event occurs and cash settlement is not elected, a variety of other deliverable obligations may be delivered in lieu of the specific referenced obligation. The ability to deliver other obligations may result in a cheapest-to-deliver option (the buyer of protection’s right to choose the deliverable obligation with the lowest value following a credit event).

Credit default swap agreements on credit indices involve one party making a stream of payments to another party in exchange for the right to receive a specified return in the event of a write-down, principal shortfall, interest shortfall or default of all or part of the referenced entities comprising the credit index. A credit index is a basket of credit instruments or exposures designed to be representative of some part of the credit market as a whole. These indices are made up of reference credits that are judged by a poll of dealers to be the most liquid entities in the credit default swap market based on the sector of the index. Components of the indices may include, but are not limited to, investment grade securities, high yield securities, asset-backed

106 PIMCO CLOSED-END FUNDS

June 30, 2023

securities, emerging markets, and/or various credit ratings within each sector. Credit indices are traded using credit default swaps with standardized terms including a fixed spread and standard maturity dates. An index credit default swap references all the names in the index, and if there is a default, the credit event is settled based on that name’s weight in the index. The composition of the indices changes periodically, usually every six months, and for most indices, each name has an equal weight in the index. Credit default swaps on credit indices may be used to hedge a portfolio of credit default swaps or bonds, which is less expensive than it would be to buy many credit default swaps to achieve a similar effect. Credit default swaps on indices are instruments for protecting investors owning bonds against default, and traders use them to speculate on changes in credit quality.

Implied credit spreads, represented in absolute terms, utilized in determining the market value of credit default swap agreements on corporate, loan, sovereign, U.S. municipal or U.S. Treasury issues as of period end, if any, are disclosed in the Notes to Schedules of Investments. They serve as an indicator of the current status of payment/performance risk and represent the likelihood or risk of default for the reference entity. The implied credit spread of a particular referenced entity reflects the cost of buying/selling protection and may include upfront payments required to be made to enter into the agreement. Wider credit spreads represent a deterioration of the referenced entity’s credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the agreement. For credit default swap agreements on asset-backed securities and credit indices, the quoted market prices and resulting values serve as the indicator of the current status of the payment/performance risk. Increasing market values, in absolute terms when compared to the notional amount of the swap, represent a deterioration of the referenced entity’s credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the agreement.

The maximum potential amount of future payments (undiscounted) that a Fund as a seller of protection could be required to make under a credit default swap agreement equals the notional amount of the agreement. Notional amounts of each individual credit default swap agreement outstanding as of period end for which a Fund is the seller of protection are disclosed in the Notes to Schedules of Investments. These potential amounts would be partially offset by any recovery values of the respective referenced obligations, upfront payments received upon entering into the agreement, or net amounts received from the settlement of buy protection credit default swap agreements entered into by a Fund for the same referenced entity or entities.

Interest Rate Swap Agreements  may be entered into to help hedge against interest rate risk exposure and to maintain a Fund’s ability to

generate income at prevailing market rates. The value of the fixed rate bonds that the Funds hold may decrease if interest rates rise. To help hedge against this risk and to maintain its ability to generate income at prevailing market rates, a Fund may enter into interest rate swap agreements. Interest rate swap agreements involve the exchange by a Fund with another party for their respective commitment to pay or receive interest on the notional amount of principal. Certain forms of interest rate swap agreements may include: (i) interest rate caps, under which, in return for a premium, one party agrees to make payments to the other to the extent that interest rates exceed a specified rate, or "cap," (ii) interest rate floors, under which, in return for a premium, one party agrees to make payments to the other to the extent that interest rates fall below a specified rate, or "floor," (iii) interest rate collars, under which a party sells a cap and purchases a floor or vice versa in an attempt to protect itself against interest rate movements exceeding given minimum or maximum levels, (iv) callable interest rate swaps, under which the buyer pays an upfront fee in consideration for the right to early terminate the swap transaction in whole, at zero cost and at a predetermined date and time prior to the maturity date, (v) spreadlocks, which allow the interest rate swap users to lock in the forward differential (or spread) between the interest rate swap rate and a specified benchmark, or (vi) basis swaps, under which two parties can exchange variable interest rates based on different segments of money markets.

Total Return Swap Agreements  are entered into to gain or mitigate exposure to the underlying reference asset. Total return swap agreements involve commitments where single or multiple cash flows are exchanged based on the price of an underlying reference asset and on a fixed or variable interest rate. Total return swap agreements may involve commitments to pay interest in exchange for a market-linked return. One counterparty pays out the total return of a specific underlying reference asset, which may include a single security, a basket of securities, or an index, and in return receives a fixed or variable rate. At the maturity date, a net cash flow is exchanged where the total return is equivalent to the return of the underlying reference asset less a financing rate, if any. As a receiver, a Fund would receive payments based on any net positive total return and would owe payments in the event of a net negative total return. As the payer, a Fund would owe payments on any net positive total return, and would receive payments in the event of a net negative total return.

7. PRINCIPAL AND OTHER RISKS

(a) Principal Risks

In the normal course of business, the Funds trade financial instruments and enter into financial transactions where risk of potential loss exists due to such things as changes in the market (market risk) or failure or inability of the other party to a transaction to perform (credit and counterparty risk).

Asset Allocation Risk  is the risk that a Fund could lose money as a result of less than optimal or poor asset allocation decisions. A Fund could miss attractive investment opportunities by underweighting markets that subsequently experience significant returns and could lose value by overweighting markets that subsequently experience significant declines.

Call Risk  is the risk that an issuer may exercise its right to redeem a fixed income security earlier than expected (a call). Issuers may call outstanding securities prior to their maturity for a number of reasons (e.g., declining interest rates, changes in credit spreads and improvements in the issuer’s credit quality). If an issuer calls a security in which the Fund has invested, the Fund may not recoup the full amount of its initial investment or may not realize the full anticipated earnings from the investment and may be forced to reinvest in lower-yielding securities, securities with greater credit risks or securities with other, less favorable features.

Collateralized Bond Obligations, Collateralized Loan Obligations and Collateralized Debt Obligations Risk  is the risk that an investment in a CLO, CBO or other CDO depends largely on the type of the collateral securities and the class/tranche of the instrument in which the Fund invests. In addition to the normal risks associated with debt instruments (e.g., interest rate risk and credit risk), CLOs, CBOs and CDOs carry additional risks including, but not limited to: (i) the possibility that distributions from the collateral will not be adequate to make interest or other payments; (ii) the risk that the quality of the collateral may decline in value or default; (iii) the risk that the Fund may invest in CBOs, CLOs or other CDOs that are subordinate to other classes; and (iv) the risk that the complex structure of the security may

not be fully understood at the time of investment and may produce disputes with the issuer or others and may produce unexpected investment results.

Collateralized Loan Obligations Risk  is the risk of investing in a trust typically collateralized by a pool of loans issued by banks, corporations or any other public or private entity or person, which may include, among others, domestic and foreign senior secured loans, senior unsecured loans and subordinate or mezzanine loans, including loans that may be rated below investment grade or equivalent unrated loans (“Collateralized Loan Obligations Risk”) or (“CLOs”). In addition to the normal risks associated with debt instruments (e.g., interest rate risk and credit risk), CLOs carry additional risks including, but not limited to: (i) the possibility that distributions from the collateral will not be adequate to make interest or other payments; (ii) the risk that the quality of the collateral may decline in value or default; (iii) the risk that the Fund may invest in CBOs, CLOs or other CDOs that are subordinate to other classes; and (iv) the complex structure of the security may not be fully understood at the time of investment and may produce disputes with the issuer or others and may produce unexpected investment results.

Confidential Information Access Risk  is the risk that, in managing the Fund (and other PIMCO clients), PIMCO may from time to time have the opportunity to receive material, non-public information (“Confidential Information”) about the issuers of certain investments, including, without limitation, senior floating rate loans, other loans and related investments being considered for acquisition by the Fund or held in the Fund’s portfolio. If PIMCO intentionally or unintentionally comes into possession of Confidential Information, it may be unable,

ANNUAL REPORT | JUNE 30, 2023 109

Notes to Financial Statements (Cont.)

potentially for a substantial period of time, to purchase or sell investments to which such Confidential Information relates.

Contingent Convertible Securities Risk  is the risk of investing in contingent convertible securities, including the risk that interest payments will be cancelled by the issuer or a regulatory authority, the risk of ranking junior to other creditors in the event of a liquidation or other bankruptcy-related event as a result of holding subordinated debt, the risk of the Fund’s investment becoming further subordinated as a result of conversion from debt to equity, the risk that the principal amount due can be written down to a lesser amount (including potentially to zero), and the general risks applicable to fixed income investments, including interest rate risk, credit risk, market risk and liquidity risk, any of which could result in losses to the Fund.

Convertible Securities Risk  is the risk that the market values of convertible securities may decline as interest rates increase and, conversely, may increase as interest rates decline. A convertible security’s market value, however, tends to reflect the market price of the common stock of the issuing company when that stock price approaches or is greater than the convertible security’s “conversion price.” The conversion price is defined as the predetermined price at which the convertible security could be exchanged for the associated stock. As the market price of the underlying common stock declines, the price of the convertible security tends to be influenced more by the yield of the convertible security. Thus, it may not decline in price to the same extent as the underlying common stock. In the event of a liquidation of the issuing company, holders of convertible securities may be paid before the company’s common stockholders but after holders of any senior debt obligations of the company. Consequently, the issuer’s convertible securities generally entail less risk than its common stock but more risk than its debt obligations. Convertible securities are often rated below investment grade or not rated.

Counterparty Risk  is the risk that the Fund will be subject to credit risk with respect to the counterparties to the derivative contracts and other instruments entered into by the Fund or held by special purpose or structured vehicles in which the Fund invests. If a counterparty becomes bankrupt or otherwise fails to perform its obligations under a derivative contract due to financial difficulties, the Fund may experience significant delays in obtaining any recovery (including recovery of any collateral it has provided to the counterparty) in a dissolution, assignment for the benefit of creditors, liquidation, winding-up, bankruptcy, or other analogous proceeding.

“Covenant-lite” Obligations Risk  is the risk that covenant-lite obligations contain fewer maintenance covenants than other obligations, or no maintenance covenants, and may not include terms that allow the lender to monitor the performance of the borrower and

declare a default if certain criteria are breached. Covenant-lite loans may carry more risk than traditional loans as they allow individuals and corporations to engage in activities that would otherwise be difficult or impossible under a covenant- heavy loan agreement. In the event of default, covenant-lite loans may exhibit diminished recovery values as the lender may not have the opportunity to negotiate with the borrower prior to default.

Credit Default Swaps Risk  is the risk of investing in credit default swaps, including illiquidity risk, counterparty risk, leverage risk and credit risk. A buyer generally also will lose its investment and recover nothing should no credit event occur and the swap is held to its termination date. When the Fund acts as a seller of a credit default swap, it is exposed to many of the same risks of leverage described herein. As the seller, a Fund would receive a stream of payments over the term of the swap agreement provided that no event of default has occurred with respect to the referenced debt obligation upon which the swap is based. A Fund would effectively add leverage to its portfolio because, if a default occurs, the stream of payments may stop and, in addition to its total net assets, the Fund would be subject to investment exposure on the notional amount of the swap. In addition, selling credit default swaps may not be profitable for the Fund if no secondary market exists or the Fund is otherwise unable to close out these transactions at advantageous times.

Credit Risk  is the risk that a Fund could lose money if the issuer or guarantor of a fixed income security (including a security purchased with securities lending collateral), the counterparty to a derivatives contract, or the issuer or guarantor of collateral, repurchase agreement or a loan of portfolio securities, is unable or unwilling, or is perceived (whether by market participants, rating agencies, pricing services or otherwise) as unable or unwilling, to meet its financial obligations. The risk that such issuer, guarantor or counterparty is less willing or able to do so is heightened in market environments where interest rates are rising. Securities are subject to varying degrees of credit risk, which are often reflected in credit ratings.

Currency Risk  is the risk that investments denominated in foreign (non-U.S.) currencies or that trade in and receive revenues in, foreign (non-U.S.) currencies, or derivatives or other instruments that provide exposure to foreign (non-U.S.) currencies may decline in value, due to the risk that those currencies will decline in value relative to the U.S. dollar, or, in the case of hedging positions, that the U.S. dollar will decline in value relative to the currency being hedged.

Cyber Security Risk  is the risk that, as the use of technology has become more prevalent in the course of business, the Funds have become potentially more susceptible to operational and information security risks resulting from breaches in cyber security. A breach in

110 PIMCO CLOSED-END FUNDS

June 30, 2023

cyber security refers to both intentional and unintentional cyber events from outside threat actors or internal resources that may, among other things, cause a Fund to lose proprietary information, suffer data corruption and/or destruction or lose operational capacity, result in the unauthorized release or other misuse of confidential information, or otherwise disrupt normal business operations. Cyber security failures or breaches may result in financial losses to a Fund and its shareholders.

These failures or breaches may also result in disruptions to business operations, potentially resulting in financial losses; interference with a Fund’s ability to calculate its net asset value, process shareholder transactions or otherwise transact business with shareholders; impediments to trading; violations of applicable privacy and other laws; regulatory fines; penalties; third party claims in litigation; reputational damage; reimbursement or other compensation costs; additional compliance and cyber security risk management costs and other adverse consequences. In addition, substantial costs may be incurred in order to prevent any cyber incidents in the future. There is also a risk that cyber security breaches may not be detected. The Fund and its shareholders may suffer losses as a result of a cyber security breach related to the Fund, its service providers, trading counterparties or the issuers in which the Fund invests.

Debt Securities Risk  is the risk that prices of bonds and other fixed income securities will generally increase as interest rates fall and decrease as interest rates rise. Income from the Fund’s portfolio may decline if the Fund invests the proceeds from matured, traded or called fixed income securities at market interest rates that are below the portfolio’s current earnings rate. The value of most bond funds and fixed income securities are impacted by changes in interest rates. Bonds and bond funds with longer durations tend to be more sensitive and more volatile than securities with shorter durations; bond prices generally fall as interest rates rise.

Derivatives Risk  is the risk of investing in derivative instruments (such as forwards, futures, swaps and structured securities) and other similar investments, including leverage, liquidity, interest rate, market, counterparty (including credit), operational, legal and management risks, and valuation complexity. Changes in the value of a derivative or other similar investment may not correlate perfectly with, and may be more sensitive to market events than, the underlying asset, rate or index, and a Fund could lose more than the initial amount invested. Changes in the value of a derivative or other similar instrument may also create margin delivery or settlement payment obligations for a Fund. A Fund’s use of derivatives may result in losses to a Fund, a reduction in a Fund’s returns and/or increased volatility. Over-the-counter (“OTC”) derivatives or other similar investments are also subject to the risk that a counterparty to the transaction will not fulfill its contractual obligations to the other

party, as many of the protections afforded to centrally- cleared derivative transactions might not be available for OTC derivatives or other similar investments. The primary credit risk on derivatives or other similar investments that are exchange- traded or traded through a central clearing counterparty resides with a Fund’s clearing broker, or the clearinghouse. Changes in regulation relating to a registered fund’s use of derivatives and related instruments could potentially limit or impact the Fund’s ability to invest in derivatives, limit a Fund’s ability to employ certain strategies that use derivatives or other similar investments and/ or adversely affect the value of derivatives or other similar investments and a Fund’s performance.

Distressed and Defaulted Securities Risk  is the risk of investing in the securities of financially distressed issuers, including the risk of default. These securities may fluctuate more in price and are typically less liquid. Distressed securities generally trade significantly below “par” or fall value.

The Fund also will be subject to significant uncertainty as to when, and in what manner, and for what value obligations evidenced by securities of financially distressed issuers will eventually be satisfied.

Distribution Rate Risk  is the risk that, to the extent a Fund seeks to maintain a level distribution rate, a Fund’s distribution rate may be affected by numerous factors, including but not limited to changes in realized and projected market returns, fluctuations in market interest rates, Fund performance, and other factors. There can be no assurance that a change in market conditions or other factors will not result in a change in a Fund’s distribution rate or that the rate will be sustainable in the future.

Emerging Markets Risk  is the risk of investing in emerging market securities, primarily increased foreign (non-U.S.) investment risk.

Equity Securities and Related Market Risk  is the risk that the value of equity securities, such as common stocks and preferred securities, may decline due to general market conditions which are not specifically related to a particular company or to factors affecting a particular industry or industries. Equity securities generally have greater price volatility than fixed income securities.

Focused Investment Risk  is the risk that, to the extent that the Fund focuses its investments in a particular industry, country or geographic region, the NAV of its common shares will be more susceptible to events or factors affecting companies in that industry, country or geographic region.

Foreign (Non-U.S.) Investment Risk  is the risk that investing in foreign (non-U.S.) securities may result in the Fund experiencing more rapid and extreme changes in value than a fund that invests exclusively in securities of U.S. issuers or securities that trade exclusively in U.S. markets due to smaller markets, differing reporting, accounting and

ANNUAL REPORT | JUNE 30, 2023 111

Notes to Financial Statements (Cont.)

auditing standards, increased risk of delayed settlement of portfolio transactions or loss of certificates of portfolio securities, and the risk of unfavorable foreign government actions, including nationalization, expropriation or confiscatory taxation, currency blockage, political changes, diplomatic developments or the imposition of sanctions and other similar measures. Foreign securities may also be less liquid (particularly during market closures due to local holidays or other reasons) and more difficult to value than securities of U.S. issuers.

High Yield Securities Risk  is the risk that high yield securities and unrated securities of similar credit quality (commonly known as “junk bonds”) are subject to greater levels of credit, call and liquidity risks. High yield securities are considered primarily speculative with respect to the issuer’s continuing ability to make principal and interest payments and may be more volatile than higher-rated securities of similar maturity.

Inflation/Deflation Risk  is the risk that the value of assets or income from the Fund’s investments will be worth less in the future as inflation decreases the value of payments at future dates. As inflation increases, the real value of the Fund’s portfolio could decline. Deflation risk is the risk that prices throughout the economy decline over time. Deflation may have an adverse effect on the creditworthiness of issuers and may make issuer default more likely, which may result in a decline in the value of the Fund’s portfolio and common shares.

Inflation-Indexed Security Risk  is the risk that inflation-indexed debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the value of an inflation-indexed security, including TIPS, tends to decrease when real interest rates increase and can increase when real interest rates decrease. Interest payments on inflation-indexed securities are unpredictable and will fluctuate as the principal and interest are adjusted for inflation. There can be no assurance that the inflation index used will accurately measure the real rate of inflation in the prices of goods and services. Any increase in the principal amount of an inflation- indexed debt security will be considered taxable ordinary income for the amount of the increase in the calendar year, even though the Fund will not receive the principal until maturity.

Interest Rate Risk  is the risk that fixed income securities and other instruments in the Fund’s portfolio will fluctuate in value because of a change in interest rates; a fund with a longer average portfolio duration will be more sensitive to changes in interest rates than a fund with a short average portfolio duration. Further, in market environments where interest rates are rising, issuers may be less willing or able to make principal and interest payments on fixed income investments when due.

Issuer Risk  is the risk that the value of a security may decline for a reason directly related to the issuer, such as management performance,

major litigation, investigations or other controversies, changes in financial condition or credit rating, changes in government regulations affecting the issuer or its competitive environment and strategic initiatives such as mergers, acquisitions or dispositions and the market response to any such initiatives, financial leverage, reputation or reduced demand for the issuer’s goods or services.

Leverage Risk  is the risk that certain transactions of a Fund, such as reverse repurchase agreements, loans of portfolio securities, and the use of when-issued, delayed delivery or forward commitment transactions, or derivative instruments, may give rise to leverage, magnifying gains and losses and causing a Fund to be more volatile than if it had not been leveraged. Leveraging transactions pursued by a Fund may increase its duration and sensitivity to interest rate movements. This means that leverage entails a heightened risk of loss.

Liquidity Risk  is the risk that a particular investment may be difficult to purchase or sell and that the Fund may be unable to sell illiquid investments at an advantageous time or price or possibly require a Fund to dispose of other investments at unfavorable times or prices in order to satisfy its obligations, which could prevent the Fund from taking advantage of other investment opportunities. Additionally, the market for certain investments may become illiquid under adverse market or economic conditions independent of any specific adverse changes in the conditions of a particular issuer.

Loans and Other Indebtedness; Loan Participations and Assignments Risk  is the risk that scheduled interest or principal payments will not be made in a timely manner or at all, either of which may adversely affect the values of a loan. Additionally, there is a risk that the collateral underlying a loan may be unavailable or insufficient to satisfy a borrower’s obligation, and the Fund could become part owner of any collateral if a loan is foreclosed, subjecting the Fund to costs associated with owning and disposing of the collateral.

In the event of the insolvency of the lender selling a participation, there is a risk that the Fund may be treated as a general creditor of the lender and may not benefit from any set-off between the lender and the borrower.

If a loan is foreclosed, the Fund may become owner of the loan’s collateral. The Fund may bear the costs and liabilities associated with owning and holding or disposing of the collateral.

There is the risk that the Fund may have difficulty disposing of loans and loan participations due to the lack of a liquid secondary market for loans and loan participations.

To the extent the Fund acquires loans, including bank loans, the Fund may be subject to greater levels of credit risk, call risk, settlement risk and liquidity risk than funds that do not acquire such instruments.

112 PIMCO CLOSED-END FUNDS

June 30, 2023

Management Risk  is the risk that the investment techniques and risk analyses applied by PIMCO will not produce the desired results and that actual or potential conflicts of interest, legislative, regulatory, or tax restrictions, policies or developments may affect the investment techniques available to PIMCO and the individual portfolio managers in connection with managing the Fund and may cause PIMCO to restrict or prohibit participation in certain investments. There is no guarantee that the investment objective of the Fund will be achieved.

Market Discount Risk  is the risk that the price of the Fund’s common shares of beneficial interest will fluctuate with market conditions and other factors. Shares of closed-end management investment companies frequently trade at a discount from their net asset value.

Market Disruptions Risk  is the risk of investment and operational risks associated with financial, economic and other global market developments and disruptions, including those arising from war, terrorism, market manipulation, government interventions, defaults and shutdowns, political changes or diplomatic developments, public health emergencies (such as the spread of infectious diseases, pandemics and epidemics) and natural/environmental disasters, which can all negatively impact the securities markets, interest rates, auctions, secondary trading, ratings, credit risk, inflation, deflation or other factors relating to the Fund’s investments or PIMCO’s operations and cause a Fund to lose value. Furthermore, events involving limited liquidity, defaults, non-performance or other adverse developments that affect financial institutions or the financial services industry generally, or concerns or rumors about any events of these kinds or other similar risks, have in the past and may in the future lead to market-wide liquidity problems. These events can also impair the technology and other operational systems upon which a Fund’s service providers, including PIMCO as a Fund’s investment adviser, rely, and could otherwise disrupt a Fund’s service providers’ ability to fulfill their obligations to a Fund.

Market Risk  is the risk that the value of securities owned by the Fund may go up or down, sometimes rapidly or unpredictably, due to factors affecting securities markets generally or particular industries or companies.

Mortgage-Related and Other Asset-Backed Securities Risk  is the risk of investing in mortgage-related and other asset-backed securities, including interest rate risk, extension risk, prepayment risk and credit risk.

Mortgage-Related Derivative Instruments Risk  is the risk associated with mortgage-related and other asset-backed instruments, privately- issued mortgage-related securities, the mortgage market, the real estate industry, derivatives and credit default swaps. See “Mortgage- Related and Other Asset-Backed Instruments Risk,” “Privately-Issued Mortgage-Related Securities Risk,” “Derivatives Risk,” and “Credit Default Swaps Risk.”

Operational Risk  is the risk arising from factors such as processing errors, human errors, inadequate or failed internal or external processes, failures in systems and technology, changes in personnel and errors caused by third-party service providers. The occurrence of any of these failures, errors or breaches could result in a loss of information, regulatory scrutiny, reputational damage or other events, any of which could have a material adverse effect on a Fund. While a Fund seeks to minimize such events through controls and oversight, there may still be failures that could cause losses to the Fund.

Other Investment Companies Risk  is the risk that Common Shareholders may be subject to duplicative expenses to the extent the Fund invests in other investment companies. In addition, these other investment companies may utilize leverage, in which case an investment would subject the Fund to additional risks associated

with leverage.

Platform Risk is the risk  resulting from the fact that the Alt Lending ABS in which the Fund invests are typically not listed on any securities exchange and not registered under the Securities Act. In addition, the Fund anticipates that these instruments may only be sold to a limited number of investors and may have a limited or non-existent secondary market. Accordingly, the Fund currently expects that certain of the investments in Alt Lending ABS will face heightened levels of liquidity risk. Although currently, there is generally no active reliable, secondary market for certain Alt Lending ABS, a secondary market for these Alt Lending ABS may develop. If the Fund purchases Alt Lending ABS on an alternative lending platform, the Fund will have the right to receive principal and interest payments due on loans underlying the Alt Lending ABS only if the platform servicing the loans receives the borrower’s payments on such loans and passes such payments through to the Fund. If a borrower is unable or fails to make payments on a loan for any reason, the Fund may be greatly limited in its ability to recover any outstanding principal or interest due, as (among other reasons) the Fund may not have direct recourse against the borrower or may otherwise be limited in its ability to directly enforce its rights under the loan, whether through the borrower or the platform through which such loan was originated. For example, the loan may be unsecured or under- collateralized and/or it may be impracticable to commence a legal proceeding against the defaulting borrower.

Portfolio Turnover Risk  is the risk that a high portfolio turnover will result in greater expenses to the Fund, including brokerage commissions or dealer mark-ups and other transaction costs on the sale of securities and reinvestments in other securities. Such sales may result in realization of taxable capital gains (including short-term capital gains, which are generally taxed to shareholders at ordinary income tax rates when distributed net of short-term capital losses and net long-term capital losses) and may adversely affect the Fund’s after-tax returns.

ANNUAL REPORT | JUNE 30, 2023 113

Notes to Financial Statements (Cont.)

Potential Conflicts of Interest Risk — Allocation of Investment Opportunities  is the risk that PIMCO’s or any of its affiliate’s interests or the interests of its clients may conflict with those of the Funds and the results of the Fund’s investment activities may differ from those of the Fund’s affiliates, or another account managed by PIMCO or its affiliates, and it is possible that the Fund could sustain losses during periods in which one or more of the Fund’s affiliates and/or other accounts managed by PIMCO or its affiliates, including proprietary accounts, achieve profits on their trading.

Preferred Securities Risk  is the risk that certain preferred securities contain provisions that allow an issuer under certain conditions to skip or defer distributions which may require the Fund to include the amount of the deferred distribution in its taxable income for tax purposes although it does not currently receive such amount in cash. Additionally, preferred securities are subordinated to bonds and other debt securities in an issuer’s capital structure in terms of priority for corporate income and liquidation payments, and therefore will be subject to greater credit risk than those debt securities. Preferred securities may trade less frequently and in a more limited volume and may be subject to more abrupt or erratic price movements than many other securities, such as common stocks, corporate debt securities and U.S. Government securities.

Privacy and Data Security Risk  is the risk resulting from the fact that the Gramm-Leach-Bliley Act (“GLBA”) and other laws limit the disclosure of certain non-public personal information about a consumer to non-affiliated third parties and require financial institutions to disclose certain privacy policies and practices with respect to information sharing with both affiliates and non-affiliated third parties. Many states and a number of non-U.S. jurisdictions have enacted privacy and data security laws requiring safeguards on the privacy and security of consumers’ personally identifiable information. Other laws deal with obligations to safeguard and dispose of private information in a manner designed to avoid its dissemination. Privacy rules adopted by the U.S. Federal Trade Commission and the SEC implement GLBA and other requirements and govern the disclosure of consumer financial information by certain financial institutions, ranging from banks to private investment funds. U.S. platforms following certain models generally are required to have privacy policies that conform to these GLBA and other requirements. In addition, such platforms typically have policies and procedures intended to maintain platform participants’ personal information securely and dispose of it properly.

Private Placement and Restricted Securities Risk  is the risk that securities received in a private placement may be subject to strict restrictions on resale, and there may be no liquid secondary market or ready purchaser for such securities and the risk that the Fund’s investment in securities that have not been registered for public sale, but that are

eligible for purchase and sale pursuant to Rule 144A under the Securities Act, may be relatively less liquid than registered securities traded on established securities markets. The Fund may be unable to dispose of such securities when it desires to do so, or at the most favorable time or price. Private placements may also raise valuation risks.Privately-Issued Mortgage-Related Securities Risk is the risk of nonpayment because there are no direct or indirect government or agency guarantees of payments in the pools created by non-governmental issuers.

Real Estate Risk  is the risk associated with investing in real estate investments, including investments in equity or debt securities issued by private and public real estate investments trusts (“REITs”), real estate operating companies (“REOCs”), private or public real estate-related loans and real estate-linked derivative instruments. The Fund will be subject to the risks associated with owning real estate and with the real estate industry generally.

Reinvestment Risk  is the risk that income from the Fund’s portfolio will decline if and when the Fund invests the proceeds from matured, traded or called debt obligations at market interest rates that are below the portfolio’s current earnings rate. The Fund also may choose to sell higher yielding portfolio securities and to purchase lower yielding securities to achieve greater portfolio diversification, because the portfolio managers believe the current holdings are overvalued or for other investment-related reasons.

REIT Risk  is the risk associated with investing in REITs, which are pooled investment vehicles that own, and usually operate, income- producing real estate. Some REITs also finance real estate. If a REIT meets certain requirements, including distributing to shareholders substantially all of its taxable income (other than net capital gains), then it is not typically taxed on the income distributed to shareholders. Therefore, REITs may pay higher dividends than other issuers.

Regulatory Changes Risk  is the risk that is associated with the fact that financial entities, such as investment companies and investment advisers, are generally subject to extensive government regulation and intervention. Government regulation and/or intervention may change the way the Fund is regulated, affect the expenses incurred directly by the Fund and the value of its investments, and limit and /or preclude the Fund’s ability to achieve its investment objectives. Government regulation may change frequently and may have significant adverse consequences. The Fund and the Investment Manager have historically been eligible for exemptions from certain regulations. However, there is no assurance that the Fund and the Investment Manager will continue to be eligible for such exemptions.

Regulatory Risk — Commodity Pool Operator  is the risk associated with the CFTC’s adopted regulations that subject registered investment companies and their investment advisers to regulation by the CFTC if the registered investment company invests more than a prescribed level

114 PIMCO CLOSED-END FUNDS

June 30, 2023

of its liquidation value in futures, options on futures or commodities, swaps, or other financial instruments regulated under the Commodity Exchange Act (“CEA”) and the rules thereunder (“commodity interests”), or if the Fund markets itself as providing investment exposure to such instruments. The Investment Manager is registered with the CFTC as a Commodity Pool Operator.

Regulatory Risk — LIBOR  is the risk related to the anticipated discontinuation of the London Interbank Offered Rate (“LIBOR”). Certain instruments held by the Fund rely in some fashion upon LIBOR. Although the transition process away from LIBOR for many instruments has been completed, some LIBOR use is continuing and there are potential effects related to the transition away from LIBOR or continued use of LIBOR on a Fund, or on certain instruments in which a Fund invests can be difficult to ascertain. Any such effects of the transition away from LIBOR, as well as other unforeseen effects, could result in losses to a Fund.

Repurchase Agreements Risk  is the risk that, if the party agreeing to repurchase a security should default, the Fund will seek to sell the securities which it holds, which could involve procedural costs or delays in addition to a loss on the securities if their value should fall below their repurchase price.

Risk Retention Investment Risk  is the risk associated with the Fund’s investments in risk retention tranches of commercial mortgage-backed securities (“CMBS”) or other eligible securitizations, if any (“risk retention tranches”), which are eligible residual interests typically held by the sponsors of such securitizations pursuant to the final rules implementing the credit risk retention requirements of Section 941 of the Dodd-Frank Act (the “U.S. Risk Retention Rules”). There can be no assurance that the applicable federal agencies charged with the implementation of the final U.S. Risk Retention Rules (the Federal Deposit Insurance Corporation, the Comptroller of the Currency, the Federal Reserve Board, the SEC, the Department of Housing and Urban Development, and the Federal Housing Finance Agency) could not take positions in the future that differ from the interpretation of such rules taken or embodied in such securitizations, or that the final U.S. Risk Retention Rules will not change. Furthermore, if the Fund breaches any undertakings in any risk retention agreement, it will be exposed to claims by the other parties thereto, including for any losses incurred as a result of such breach, which could be significant and exceed the value of the Fund’s investments.

Securities Lending Risk  is the risk that, when a Fund lends portfolio securities, its investment performance will continue to reflect changes in the value of the securities loaned and lose rights in the collateral or delay in recovery of the collateral if the borrower fails to return the security loaned or becomes insolvent. The Fund may pay lending fees to a party, which may be an affiliate of the Fund, arranging the loan.

Senior Debt Risk  is the risk that the Fund may be subject to greater levels of credit risk than funds that do not invest in below investment grade senior debt. The Fund may also be subject to greater levels of liquidity risk than funds that do not invest in senior debt. Restrictions on transfers in loan agreements, a lack of publicly available information and other factors may, in certain instances, make senior debt more difficult to sell at an advantageous time or price than other types of securities or instruments.

Short Exposure Risk  is the risk of entering into short sales or other short positions, including the potential loss of more money than the actual cost of the investment, and the risk that the third party to the short sale or other short position will not fulfill its contractual obligations, causing a loss to a Fund.

Smaller Company Risk  is the risk that the value of securities issued by a smaller company may go up or down, sometimes rapidly and unpredictably as compared to more widely held securities, due to narrow markets and limited resources of smaller companies. A Fund’s investments in smaller companies subject it to greater levels of credit, market and issuer risk.

Sovereign Debt Risk  is the risk that investments in fixed income instruments issued by sovereign entities may decline in value as a result of default or other adverse credit event resulting from an issuer’s inability or unwillingness to make principal or interest payments in a timely fashion.

Special Purpose Acquisition Companies (“SPACs”) Risk  is the risk that, because SPACs and similar entities are in essence “blank check” companies without operating history or ongoing business other than seeking acquisitions, the value of their securities is particularly dependent on the ability of the entity’s management to identify and complete a profitable acquisition. A SPAC’s structure may result in significant dilution of a stockholder’s share value immediately upon the completion of a business combination due to, among other reasons, interests held by the SPAC sponsor, conversion of warrants into additional shares, shares issued in connection with a business combination and/or certain embedded costs. There is no guarantee that the SPACs in which the Fund invests will complete an acquisition or that any acquisitions that are completed will be profitable. Some SPACs may pursue acquisitions only within certain industries or regions, which may increase the volatility of their prices. In addition, these securities, which are typically traded in the over-the-counter market, may be considered illiquid and/or be subject to restrictions on resale.

Structured Investments Risk  is the risk that the Fund’s investment in structured products, including, structured notes, credit-linked notes and other types of structured products bear the risks of the underlying investments, index or reference obligation and are subject to counterparty risk. The Fund may have the right to receive payments

ANNUAL REPORT | JUNE 30, 2023 115

Notes to Financial Statements (Cont.)

only from the structured product, and generally does not have direct rights against the issuer or the entity that sold the assets to be securitized. Structured products generally entail risks associated with derivative instruments.

Subprime Risk  is the risk that loans, and debt instruments collateralized by loans (including Alt Lending ABS), acquired by the Fund may be subprime in quality, or may become subprime in quality. Although there is no specific legal or market definition of “subprime,” subprime loans are generally understood to refer to loans made to borrowers that display poor credit histories and other characteristics that correlate with a higher default risk. Accordingly, subprime loans, and debt instruments secured by such loans, have speculative characteristics and are subject to heightened risks, including the risk of nonpayment of interest or repayment of principal, and the risks associated with investments in high yield securities. In addition, these instruments could be subject to increased regulatory scrutiny. The Fund is not restricted by any particular borrower credit risk criteria and/or qualifications when acquiring loans or debt instruments collateralized by loans.

Subsidiary Risk  is the risk that, by investing in a Fund’s subsidiary, the Fund would be indirectly exposed to the risks associated with the subsidiaries’s investments. Fund subsidiaries are not registered under the 1940 Act and may not be subject to all the investor protections of the 1940 Act. There is no guarantee that the investment objective of a subsidiary will be achieved.

Synthetic Convertible Securities Risk  is the risk that the values of synthetic convertible securities will respond differently to market fluctuations than a traditional convertible security because a synthetic convertible is composed of two or more separate securities or instruments, (such as a debt security and a warrant or option to purchase another security), each with its own market value. Synthetic convertible securities are also subject to the risks associated with derivatives. In addition, if the value of the underlying common stock or the level of the index involved in the convertible element falls below the strike price of the warrant or option, the warrant or option may lose all value.

Tax Risk  is the risk that if, in any year, the Fund were to fail to qualify for treatment as a regulated investment company under the Tax Code, and were ineligible to or did not otherwise cure such failure, the Fund would be subject to tax on its taxable income at corporate rates and, when such income is distributed, shareholders would be subject to a further tax to the extent of the Fund’s current or accumulated earnings and profits.

U.S. Government Securities Risk  is the risk that the obligations supported by (i) the full faith and credit of the United States, (ii) the right of the issuer to borrow from the U.S. Treasury, (iii) the discretionary authority of the U.S. Government to purchase the

agency’s obligations (iv) or only by the credit of the agency, instrumentality or corporation will not be satisfied in full, or that such obligations will decrease in value or default. U.S. government securities are subject to market risk, interest rate risk and credit risk.

Valuation Risk  is the risk that fair value pricing used when market quotations are not readily available may not result in adjustments to the prices of securities or other assets, or that fair value pricing may not reflect actual market value. It is possible that the fair value determined in good faith for a security or other asset will be materially different from quoted or published prices, from the prices used by others for the same security or other asset and/or from the value that actually could be or is realized upon the sale of that security or other asset.

Zero-Coupon Bond, Step-Ups and Payment-in-Kind Securities Risk is the risk presented by the market prices of zero-coupon, step ups and payment-in-kind securities generally being more volatile than the prices of securities that pay interest periodically and in cash and being likely to respond to changes in interest rates to a greater degree than other types of debt securities with similar maturities and credit quality. In addition, as these securities may not pay cash interest, the Fund’s investment exposure to these securities and their risks, including credit risk, will increase during the time these securities are held in the Fund’s portfolio.

(b) Other Risks

In general, a Fund may be subject to additional risks, including, but not limited to, risks related to government regulation and intervention in financial markets, operational risks, risks associated with financial, economic and global market disruptions, and cyber security risks. Please see a Fund’s Prospectus and Statement of Additional Information for a more detailed description of the risks of investing in a Fund. Please see the Important Information section of this report for additional discussion of certain regulatory and market developments that may impact a Fund’s performance.

8. MASTER NETTING ARRANGEMENTS

A Fund may be subject to various netting arrangements (“Master Agreements”) with select counterparties. Master Agreements govern the terms of certain transactions, and are intended to reduce the counterparty risk associated with relevant transactions by specifying credit protection mechanisms and providing standardization that is intended to improve legal certainty. Each type of Master Agreement governs certain types of transactions. Different types of transactions may be traded out of different legal entities or affiliates of a particular organization, resulting in the need for multiple agreements with a single counterparty. As the Master Agreements are specific to unique operations of different asset types, they allow a Fund to close out and net its total exposure to a counterparty in the event of a default with respect to all the transactions governed under a single Master

116 PIMCO CLOSED-END FUNDS

June 30, 2023

Agreement with a counterparty. For financial reporting purposes the Statements of Assets and Liabilities generally present derivative assets and liabilities on a gross basis, which reflects the full risks and exposures prior to netting.

Master Agreements can also help limit counterparty risk by specifying collateral posting arrangements at pre-arranged exposure levels. Under most Master Agreements, collateral is routinely transferred if the total net exposure to certain transactions (net of existing collateral already in place) governed under the relevant Master Agreement with a counterparty in a given account exceeds a specified threshold, which typically ranges from zero to $250,000 depending on the counterparty and the type of Master Agreement. United States Treasury Bills and U.S. dollar cash are generally the preferred forms of collateral, although other securities may be used depending on the terms outlined in the applicable Master Agreement. Securities and cash pledged as collateral are reflected as assets on the Statements of Assets and Liabilities as either a component of Investments at value (securities) or Deposits with counterparty. Cash collateral received is not typically held in a segregated account and as such is reflected as a liability on the Statements of Assets and Liabilities as Deposits from counterparty. The market value of any securities received as collateral is not reflected as a component of NAV. A Fund’s overall exposure to counterparty risk can change substantially within a short period, as it is affected by each transaction subject to the relevant Master Agreement.

Master Repurchase Agreements and Global Master Repurchase Agreements (individually and collectively “Master Repo Agreements”) govern repurchase, reverse repurchase, and certain sale-buyback transactions between a Fund and select counterparties. Master Repo Agreements maintain provisions for, among other things, initiation, income payments, events of default, and maintenance of collateral. The market value of transactions under the Master Repo Agreement, collateral pledged or received, and the net exposure by counterparty as of period end are disclosed in the Notes to Schedules of Investments.

Master Securities Forward Transaction Agreements (“Master Forward Agreements”) govern certain forward settling transactions, such as TBA securities, delayed-delivery or certain sale-buyback transactions by and between a Fund and select counterparties. The Master Forward Agreements maintain provisions for, among other things, transaction initiation and confirmation, payment and transfer, events of default, termination, and maintenance of collateral. The market value of forward settling transactions, collateral pledged or received, and the net exposure by counterparty as of period end is disclosed in the Notes to Schedules of Investments.

Customer Account Agreements and related addenda govern cleared derivatives transactions such as futures, options on futures, and cleared

OTC derivatives. Such transactions require posting of initial margin as determined by each relevant clearing agency which is segregated in an account at a futures commission merchant (“FCM”) registered with the CFTC. In the United States, counterparty risk may be reduced as creditors of an FCM cannot have a claim to Fund assets in the segregated account. Portability of exposure reduces risk to the Funds. Variation margin, which reflects changes in market value, is generally exchanged daily, but may not be netted between futures and cleared OTC derivatives unless the parties have agreed to a separate arrangement in respect of portfolio margining. The market value or accumulated unrealized appreciation (depreciation), initial margin posted, and any unsettled variation margin as of period end are disclosed in the Notes to Schedules of Investments.

Prime Broker Arrangements may be entered into to facilitate execution and/or clearing of listed equity option transactions or short sales of equity securities between a Fund and selected counterparties. The arrangements provide guidelines surrounding the rights, obligations, and other events, including, but not limited to, margin, execution, and settlement. These agreements maintain provisions for, among other things, payments, maintenance of collateral, events of default, and termination. Margin and other assets delivered as collateral are typically in the possession of the prime broker and would offset any obligations due to the prime broker. The market values of listed options and securities sold short and related collateral are disclosed in the Notes to Schedules of Investments.

International Swaps and Derivatives Association, Inc. Master Agreements and Credit Support Annexes (“ISDA Master Agreements”) govern bilateral OTC derivative transactions entered into by a Fund with select counterparties. ISDA Master Agreements maintain provisions for general obligations, representations, agreements, collateral posting and events of default or termination. Events of termination include conditions that may entitle counterparties to elect to terminate early and cause settlement of all outstanding transactions under the applicable ISDA Master Agreement. Any election to terminate early could be material to the financial statements. The ISDA Master Agreement may contain additional provisions that add counterparty protection beyond coverage of existing daily exposure if the counterparty has a decline in credit quality below a predefined level or as required by regulation. Similarly, if required by regulation, the Funds may be required to post additional collateral beyond coverage of daily exposure. These amounts, if any, may (or if required by law, will) be segregated with a third-party custodian. To the extent the Funds are required by regulation to post additional collateral beyond coverage of daily exposure, they could potentially incur costs, including in procuring eligible assets to meet collateral requirements, associated with such posting. The market value of OTC financial derivative instruments,

collateral received or pledged, and net exposure by counterparty as of period end are disclosed in the Notes to Schedules of Investments.

9. FEES AND EXPENSES

(a) Management Fee  PIMCO is a majority-owned subsidiary of Allianz Asset Management of America LLC (“Allianz Asset Management”) and serves as the Manager to the Funds, pursuant to an investment management agreement. Pursuant to the Investment Management Agreement with PIMCO (the “Agreement”), and subject to the supervision of the Board, PIMCO is responsible for providing to each Fund investment guidance and policy direction in connection with the management of the Fund, including oral and written research, analysis, advice, and statistical and economic data and information. In addition, pursuant to the Agreement and subject to the general supervision of the Board, PIMCO, at its expense, provides or causes to be furnished most other supervisory and administrative services the Funds require, including but not limited to, expenses of most third-party service providers (e.g., audit, custodial, legal, transfer agency, printing) and other expenses, such as those associated with insurance, proxy solicitations and mailings for shareholder meetings, NYSE listing and related fees, tax services, valuation services and other services the Funds require for their daily operations.

Pursuant to the Agreement, PIMCO receives an annual fee, payable monthly, at the annual rates shown in the table below:

Fund Name	Annual Rate
PIMCO Corporate & Income Opportunity Fund		0.65%	(1)
PIMCO Corporate & Income Strategy Fund		0.81%	(1)
PIMCO High Income Fund		0.76%	(1)
PIMCO Income Strategy Fund		0.86%	(2)
PIMCO Income Strategy Fund II		0.83%	(2)

(1) Management fees calculated based on the Fund’s average daily net asset value (including daily net assets attributable to any preferred shares of the Fund that may be outstanding).

(2) Management fees calculated based on the Fund’s average weekly “total managed assets”. Total managed assets include total assets of each Fund (including any assets attributable to any preferred shares or other forms of leverage that may be outstanding) minus accrued liabilities (other than liabilities representing leverage).

In rendering investment advisory services to each Fund, PIMCO may use the resources of one or more foreign (non-U.S.) affiliates that are not registered under the Investment Advisers Act of 1940, as amended (the “Advisers Act”) (the “PIMCO Overseas Affiliates”), to provide portfolio management, research and trading services to the Fund under the Memorandums of Understanding (“MOUs”). Each of the PIMCO Overseas Affiliates are Participating Affiliates of PIMCO as that term is used in relief granted by the staff of the SEC allowing U.S. registered advisers to use investment advisory and trading resources of unregistered advisory affiliates subject to the regulatory supervision of the registered

adviser. Each PIMCO Overseas Affiliate and any of their respective employees who provide services to the Funds are considered under the MOUs to be “associated persons” of PIMCO as that term is defined in the Advisers Act for purposes of PIMCO’s required supervision.

(b) Fund Expenses  Each Fund bears other expenses, which may vary and affect the total level of expenses paid by shareholders, such as (i) salaries and other compensation or expenses, including travel expenses of any of the Fund’s executive officers and employees, if any, who are not officers, directors, shareholders, members, partners or employees of PIMCO or its subsidiaries or affiliates; (ii) taxes and governmental fees, if any, levied against the Fund; (iii) brokerage fees and commissions and other portfolio transaction expenses incurred by or for the Fund (including, without limitation, fees and expenses of outside legal counsel or third-party consultants retained in connection with reviewing, negotiating and structuring specialized loans and other investments made by the Fund, subject to specific or general authorization by the Board (for example, so-called “broken-deal costs” (e.g., fees, costs, expenses and liabilities, including, for example, due diligence-related fees, costs, expenses and liabilities, with respect to unconsummated investments))); (iv) expenses of the Fund’s securities lending (if any), including any securities lending agent fees, as governed by a separate securities lending agreement; (v) costs, including interest expenses, of borrowing money or engaging in other types of leverage financing, including, without limitation, through the use by the Fund of reverse repurchase agreements, tender option bonds, bank borrowings and credit facilities; (vi) costs, including dividend and/or interest expenses and other costs (including, without limitation, offering and related legal costs, fees to brokers, fees to auction agents, fees to transfer agents, fees to ratings agencies and fees to auditors associated with satisfying ratings agency requirements for preferred shares or other securities issued by the Fund and other related requirements in the Fund’s organizational documents) associated with the Fund’s issuance, offering, redemption and maintenance of preferred shares, commercial paper or other senior securities for the purpose of incurring leverage; (vii) fees and expenses of any underlying funds or other pooled vehicles in which the Fund invests; (viii) dividend and interest expenses on short positions taken by the Fund; (ix) fees and expenses, including travel expenses, and fees and expenses of legal counsel retained for their benefit, of Trustees who are not officers, employees, partners, shareholders or members of PIMCO or its subsidiaries or affiliates; (x) extraordinary expenses, including extraordinary legal expenses, that may arise, including expenses incurred in connection with litigation, proceedings, other claims, and the legal obligations of the Fund to indemnify its Trustees, officers, employees, shareholders, distributors, and agents with respect thereto; (xi) organizational and offering expenses of the Fund, including with respect to share offerings, such as rights offerings and shelf

118 PIMCO CLOSED-END FUNDS

June 30, 2023

offerings, following the Fund’s initial offering, and expenses associated with tender offers and other share repurchases and redemptions; and (xii) expenses of the Fund which are capitalized in accordance with U.S. GAAP. Without limiting the generality or scope of the foregoing, it is understood that the Funds may bear such expenses either directly or indirectly through contracts or arrangements with PIMCO or an affiliated or unaffiliated third party.

Each of the Trustees of the Funds who is not an interested person under Section 2(a)(19) of the Act, (the “Independent Trustees”), also serves as a trustee of a number of other closed-end funds for which PIMCO serves as investment manager (together with the Funds, the

“PIMCO Closed-End Funds”), as well as PIMCO California Flexible Municipal Income Fund, PIMCO Flexible Emerging Markets Income Fund, PIMCO Flexible Credit Income Fund and PIMCO Flexible Municipal Income Fund, each a closed end management investment company managed by PIMCO that is operated as an “interval fund” and PIMCO Managed Accounts Trust, an open-end management investment company with multiple series for which PIMCO serves as investment adviser and administrator.

The Funds pay no compensation directly to any Trustee or any other officer who is affiliated with the Manager, all of whom receive remuneration for their services to the Funds from the Manager or its affiliates.

10. RELATED PARTY TRANSACTIONS

The Manager is a related party. Fees payable to this party are disclosed in Note 9, Fees and Expenses, and the accrued related party fee amounts are disclosed on the Statements of Assets and Liabilities.

Certain Funds are permitted to purchase or sell securities from or to certain related affiliated funds under specified conditions outlined in procedures adopted by the Board. The procedures have been designed to ensure that any purchase or sale of securities by the Funds from or to another fund or portfolio that are, or could be, considered an affiliate, or an affiliate of an affiliate, by virtue of having a common investment adviser (or affiliated investment advisers), common Trustees and/or common officers complies with applicable SEC rules and interpretations under the Act. Further, as defined under the procedures, each transaction is effected at the current market price. Purchases and sales of securities pursuant to applicable SEC rules and interpretations under the Act for the period ended June 30, 2023, were as follows (amounts in thousands†):

Fund Name	Purchases		Sales		Realized Gain/(Loss)
PIMCO Corporate & Income Opportunity Fund	$	19,171	$	30,562	$	(677	)
PIMCO Corporate & Income Strategy Fund		2,847		2,421		(32	)
PIMCO High Income Fund		5,702		2,455		(146	)
PIMCO Income Strategy Fund		1,963		2,021		(4	)
PIMCO Income Strategy Fund II		9,512		9,195		(83	)

†  A zero balance may reflect actual amounts rounding to less than one thousand.

11. GUARANTEES AND INDEMNIFICATIONS

Under each Fund’s organizational documents, each Trustee and officer is indemnified, to the extent permitted by the Act, against certain liabilities that may arise out of performance of their duties to the Funds. Additionally, in the normal course of business, the Funds enter into contracts that contain a variety of indemnification clauses. The Funds’ maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Funds that have not yet occurred. However, the Funds have not had prior claims or losses pursuant to these contracts.

12. PURCHASES AND SALES OF SECURITIES

The length of time a Fund has held a particular security is not generally a consideration in investment decisions. A change in the securities held by a Fund is known as “portfolio turnover.” Each Fund may engage in

frequent and active trading of portfolio securities to achieve its investment objective(s), particularly during periods of volatile market movements. High portfolio turnover may involve correspondingly greater transaction costs, including brokerage commissions or dealer mark-ups and other transaction costs on the sale of securities and reinvestments in other securities, which are borne by the Fund. Such sales may also result in realization of taxable capital gains, including short-term capital gains (which are generally taxed at ordinary income tax rates when distributed to shareholders). The transaction costs associated with portfolio turnover may adversely affect a Fund’s performance. The portfolio turnover rates are reported in the Financial Highlights.

ANNUAL REPORT | JUNE 30, 2023 119

13. COMMON SHARES OFFERING

Each of PIMCO Corporate & Income Opportunity Fund (“PTY”), PIMCO Corporate & Income Strategy Fund (“PCN”), PIMCO High Income Fund (“PHK”), PIMCO Income Strategy Fund (“PFL”) and PIMCO Income Strategy Fund II (“PFN”) has authorized an unlimited number of Common Shares at a par value of $0.00001 per share (each of the foregoing Fund’s shares as the context requires, “Common Shares”).

As of the end of the reporting period, each Fund had an effective registration statement on file with the SEC authorizing the Fund to issue shares through the “shelf” registration process pursuant to Rule 415 under the Securities Act (each, a “Shelf Registration Statement”). Pursuant to such Shelf Registration Statements, each Fund may offer and sell Common Shares having an aggregate offering value of up to amounts shown in the table below. Each Fund may have had one or

more prior Shelf Registration Statements in effect during this and/or previous fiscal periods authorizing the sale of additional Common Shares.

Each Fund has entered into a sales agreement (a “Sales Agreement”) with JonesTrading Institutional Services LLC (“JonesTrading”), pursuant to which each Fund may offer and sell its Common Shares offered by an applicable prospectus supplement through JonesTrading as its agent in negotiated transactions or transactions that are deemed to be “at the market” as defined in Rule 415 under the Securities Act, including sales made directly on the NYSE or sales made to or through a market maker other than on an exchange, at prices related to the prevailing market prices or at negotiated prices. Each Fund will pay JonesTrading compensation of up to 1.00% of the gross proceeds with respect to sales of the Common Shares actually effected by JonesTrading under the Sales Agreement.

The aggregate dollar amount of Common Shares registered under each Fund’s Shelf Registration Statement (or its most recent prospectus supplement, if less than such registered amount) as of the end of the periods described below, as well as number of Common Shares sold and total amount of offering proceeds (net of offering costs, if any) received by each Fund under one or more Shelf Registration Statements during the Fund’s most recent and prior fiscal periods were as follows:

	PTY				PCN				PHK

Offering proceeds (net of offering costs)	$	19,501,911	$	9,700,744	$	33,368,586	$	12,151,886

A Fund may not sell any Common Shares at a price below the NAV of such Common Shares, exclusive of any distributing commission or discount. Sales of the Common Shares, if any, may be made in negotiated transactions or transactions that are deemed to be “at the

market”, including sales made directly on the NYSE or sales made to or through a market maker other than on an exchange, at prices related to the prevailing market prices or at negotiated prices.

14. AUCTION-RATE PREFERRED SHARES

Each series of Auction-Rate Preferred Shares (“ARPS”) outstanding of each Fund has a liquidation preference of $25,000 per share plus any accumulated, unpaid dividends. Dividends are accumulated daily at an

annual rate that is typically reset every seven days through auction procedures (or through default procedures in the event of failed auctions). Distributions of net realized capital gains, if any, are paid at least annually.

For the period ended June 30, 2023, the annualized dividend rates on the ARPS ranged from:

Fund Name	Shares Issued Outstanding		High		Low		As of June 30, 2023
PIMCO Corporate & Income Opportunity Fund
Series M		1,748		10.192%		3.102%		10.192%

Series F		638		10.236%		3.048%		10.196%

Each Fund is subject to certain limitations and restrictions while ARPS are outstanding. Failure to comply with these limitations and restrictions could preclude a Fund from declaring or paying any dividends or distributions to common shareholders or repurchasing common shares and/or could trigger the mandatory redemption of ARPS at their liquidation preference plus any accumulated, unpaid dividends.

Ratings agencies may change their methodologies for evaluating and providing ratings for shares of closed-end funds at any time and in their

sole discretion, which may affect the rating (if any) of a Fund’s shares. In addition, ratings downgrades may result in an increase to the Fund’s Maximum Rate, as defined below.

Auction-Rate Preferred shareholders of each Fund, who are entitled to one vote per share, generally vote together with the common shareholders of the Fund but vote separately as a class to elect two Trustees of the Fund and on certain matters adversely affecting the rights of the ARPS.

ANNUAL REPORT | JUNE 30, 2023 121

Notes to Financial Statements (Cont.)

Since mid-February 2008, holders of ARPS issued by the Funds have been directly impacted by a lack of liquidity, which has similarly affected ARPS holders in many of the nation’s closed-end funds. Since then, regularly scheduled auctions for ARPS issued by the Funds have consistently “failed” because of insufficient demand (bids to buy shares) to meet the supply (shares offered for sale) at each auction. In a failed auction, ARPS holders cannot sell all, and may not be able to sell any, of their shares tendered for sale. While repeated auction failures have affected the liquidity for ARPS, they do not constitute a default or automatically alter the credit quality of the ARPS, and ARPS holders have continued to receive dividends at the defined “maximum rate,” as defined for the Funds in the table below:

Fund Name		Applicable %			Reference Rate		Maximum Rate(1)
PIMCO Corporate & Income Opportunity Fund			200%	x	7-day “AA” Financial Composite Commercial Paper Rates	=		Maximum Rate for PTY
PIMCO Corporate & Income Strategy Fund			160%	x	7-day “AA” Financial Composite Commercial Paper Rates	=		Maximum Rate for PCN
PIMCO High Income Fund			160%	x	7-day “AA” Financial Composite Commercial Paper Rates	=		Maximum Rate for PHK
PIMCO Income Strategy Fund	The higher of		200% 2.00%	x +	LIBOR Replacement Rate(3) OR LIBOR Replacement Rate(3)	= =		Maximum Rate for PFL	(2)
PIMCO Income Strategy Fund II	The higher of		200% 2.00%	x +	LIBOR Replacement Rate(3) OR LIBOR Replacement Rate(3)	= =		Maximum Rate for PFN	(2)

(1)  In any event, the Maximum Rate will not be lower than 0%.

(2)  For the avoidance of doubt, the Maximum Rate for PFL and PFN may be less than the Applicable %, but will not be lower than 0%.

(3)  LIBOR Replacement Rate means prior business day’s SOFR rate plus the spread adjustment of 0.03839%.

The maximum rate is a function of short-term interest rates and is typically but not necessarily, higher than the rate that would have otherwise been set through a successful auction. If the Funds’ ARPS auctions continue to fail and the “maximum rate” payable on the ARPS rises as a result of changes in short-term interest rates, returns for the Fund’s common shareholders could be adversely affected.

There were no tender offers for the period ended June 30, 2023, and as such, the ARPS outstanding for each Fund as of June 30, 2023 remains consistent with those amounts presented in the Funds’ Annual Report to Shareholders dated December 31, 2022.

15. REGULATORY AND LITIGATION MATTERS

The Funds are not named as defendants in any material litigation or arbitration proceedings and are not aware of any material litigation or claim pending or threatened against them.

The foregoing speaks only as of the date of this report.

16. FEDERAL INCOME TAX MATTERS

Each Fund intends to qualify as a regulated investment company under Subchapter M of the Internal Revenue Code (the “Code”) and distribute all of its taxable income and net realized gains, if applicable, to shareholders. Accordingly, no provision for Federal income taxes has

been made. Due to the timing of when distributions are made by a Fund, the Fund may be subject to an excise tax of 4% of the amount by which 98% of the Fund’s annual taxable income and 98.2% of net realized gains exceed the distributions from such taxable income and realized gains for the calendar year.

A Fund may be subject to local withholding taxes, including those imposed on realized capital gains. Any applicable foreign capital gains tax is accrued daily based upon net unrealized gains, and may be payable following the sale of any applicable investments.

In accordance with U.S. GAAP, the Manager has reviewed the Funds’ tax positions for all open tax years. As of June 30, 2023, the Funds have recorded no liability for net unrecognized tax benefits relating to uncertain income tax positions they have taken or expect to take in future tax returns.

The Funds file U.S. federal, state, and local tax returns as required.

17. SUBSEQUENT EVENTS

In preparing these financial statements, the Funds’ management has evaluated events and transactions for potential recognition or disclosure through the date the financial statements were issued.

On August 14, 2023, the Funds commenced a voluntary tender offer for up to 100% of each Fund’s outstanding ARPS at a price equal to 96% with respect to PTY, 93.25% with respect to PCN and PHK and 94.25% with respect to PFL and PFN, of the ARPS’ per share liquidation preference of $25,000 per share (or $24,000 per share for PTY, $23,312.50 per share for PCN and PHK, and $23,562.50 per share of PFL and PFN) and any unpaid but accrued dividends (each, a “Tender Offer”).

Each Fund’s Tender Offer will expire at 5:00 p.m., New York City time, on September 18, 2023, unless extended.

Each Fund may determine to replace all or a portion of the leverage currently obtained through tendered ARPS with other forms of leverage, such as reverse repurchase agreements. There is no guarantee that a Fund will be able to replace all or a portion of the leverage currently obtained through tendered ARPS with leverage at comparable costs and other terms, or will elect to do so, and any replacement leverage may be at a higher interest rate and/or may result in higher costs to the Fund’s common shareholders. See “Leverage Risk” in Note 7 for a description of risks associated with the use of leverage. Additional information is available in the Tender Offer documents for each Fund, which can be obtained on the Securities and Exchange Commission’s website at www.sec.gov.

To the Board of Trustees and Shareholders of PIMCO Corporate & Income Opportunity Fund, PIMCO Corporate & Income Strategy Fund, PIMCO High Income Fund, PIMCO Income Strategy Fund and PIMCO Income Strategy Fund II

Opinions on the Financial Statements

We have audited the accompanying statements of assets and liabilities, including the schedules of investments, of PIMCO Corporate & Income Opportunity Fund, PIMCO Corporate & Income Strategy Fund, PIMCO High Income Fund, PIMCO Income Strategy Fund and PIMCO Income Strategy Fund II (hereafter collectively referred to as the “Funds”) as of June 30, 2023, the related statements of operations and cash flows for the year ended June 30, 2023, the statements of changes in net assets for the year ended June 30, 2023, for the period from August 1, 2021 to June 30, 2022, and for the year ended July 31, 2021, including the related notes, and the financial highlights for each of the periods indicated therein (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of each of the Funds as of June 30, 2023, the results of each of their operations and each of their cash flows for the year ended June 30, 2023, the changes in each of their net assets for the year ended June 30, 2023, for the period from August 1, 2021 to June 30, 2022, and for the year ended July 31, 2021 and each of the financial highlights for each of the periods indicated therein in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinions

These financial statements are the responsibility of the Funds’ management. Our responsibility is to express an opinion on the Funds’ financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Funds in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits of these financial statements in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our procedures included confirmation of securities owned as of June 30, 2023 by correspondence with the custodian, brokers and agent banks; when replies were not received from brokers or agent banks, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinions.

ANNUAL REPORT | JUNE 30, 2023 131

Dividend Reinvestment Plan

Each Fund has adopted a Dividend Reinvestment Plan (the “Plan”) which allows common shareholders to reinvest Fund distributions in additional common shares of the Fund. Equiniti Trust Company, LLC (the “Plan Agent”) serves as agent for common shareholders in administering the Plan. It is important to note that participation in the Plan and automatic reinvestment of Fund distributions does not ensure a profit, nor does it protect against losses in a declining market.

Automatic enrollment/voluntary participation  Under the Plan, common shareholders whose shares are registered with the Plan Agent (“registered shareholders”) are automatically enrolled as participants in the Plan and will have all Fund distributions of income, capital gains and returns of capital (together, “distributions”) reinvested by the Plan Agent in additional common shares of a Fund, unless the shareholder elects to receive cash. Registered shareholders who elect not to participate in the Plan will receive all distributions in cash paid by check and mailed directly to the shareholder of record (or if the shares are held in street or other nominee name, to the nominee) by the Plan Agent. Participation in the Plan is voluntary. Participants may terminate or resume their enrollment in the Plan at any time without penalty by notifying the Plan Agent online at www.astfinancial.com, by calling (844) 33-PIMCO, by writing to the Plan Agent, Equiniti Trust Company, LLC, at P.O. Box 922, Wall Street Station, New York, NY 10269-0560, or, as applicable, by completing and returning the transaction form attached to a Plan statement. A proper notification will be effective immediately and apply to each Fund’s next distribution if received by the Plan Agent at least three (3) days prior to the record date for the distribution; otherwise, a notification will be effective shortly following the Fund’s next distribution and will apply to the Fund’s next succeeding distribution thereafter. If you withdraw from the Plan and so request, the Plan Agent will arrange for the sale of your shares and send you the proceeds, minus a transaction fee and brokerage commissions.

How shares are purchased under the Plan  For each Fund distribution, the Plan Agent will acquire common shares for participants either (i) through receipt of newly issued common shares from each Fund (“newly issued shares”) or (ii) by purchasing common shares of the Fund on the open market (“open market purchases”). If, on a distribution payment date, the net asset value per common share of a Fund (“NAV”) is equal to or less than the market price per common share plus estimated brokerage commissions (often referred to as a “market premium”), the Plan Agent will invest the distribution amount on behalf of participants in newly issued shares at a price equal to the greater of (i) NAV or (ii) 95% of the market price per common share on the payment date. If the NAV is greater than the

market price per common shares plus estimated brokerage commissions (often referred to as a “market discount”) on a distribution payment date, the Plan agent will instead attempt to invest the distribution amount through open market purchases. If the Plan Agent is unable to invest the full distribution amount in open market purchases, or if the market discount shifts to a market premium during the purchase period, the Plan Agent will invest any un-invested portion of the distribution in newly issued shares at a price equal to the greater of (i) NAV or (ii) 95% of the market price per share as of the last business day immediately prior to the purchase date (which, in either case, may be a price greater or lesser than the NAV per common shares on the distribution payment date). No interest will be paid on distributions awaiting reinvestment. Under the Plan, the market price of common shares on a particular date is the last sales price on the exchange where the shares are listed on that date or, if there is no sale on the exchange on that date, the mean between the closing bid and asked quotations for the shares on the exchange on that date.

The NAV per common share on a particular date is the amount calculated on that date (normally at the close of regular trading on the New York Stock Exchange) in accordance with each Fund’s then current policies.

Fees and expenses  No brokerage charges are imposed on reinvestments in newly issued shares under the Plan. However, all participants will pay a pro rata share of brokerage commissions incurred by the Plan Agent when it makes open market purchases. There are currently no direct service charges imposed on participants in the Plan, although each Fund reserves the right to amend the Plan to include such charges. The Plan Agent imposes a transaction fee (in addition to brokerage commissions that are incurred) if it arranges for the sale of your common shares held under the Plan.

Shares held through nominees  In the case of a registered shareholder such as a broker, bank or other nominee (together, a “nominee”) that holds common shares for others who are the beneficial owners, the Plan Agent will administer the Plan on the basis of the number of common shares certified by the nominee/record shareholder as representing the total amount registered in such shareholder’s name and held for the account of beneficial owners who are to participate in the Plan. If your common shares are held through a nominee and are not registered with the Plan Agent, neither you nor the nominee will be participants in or have distributions reinvested under the Plan. If you are a beneficial owner of common shares and wish to participate in the Plan, and your nominee is unable or unwilling to become a registered shareholder and a Plan participant on your behalf, you may request that your nominee arrange to have all

132 PIMCO CLOSED-END FUNDS

(Unaudited)

or a portion of your shares re-registered with the Plan Agent in your name so that you may be enrolled as a participant in the Plan. Please contact your nominee for details or for other possible alternatives. Participants whose shares are registered with the Plan Agent in the name of one nominee firm may not be able to transfer the shares to another firm and continue to participate in the Plan.

Tax consequences  Automatically reinvested dividends and distributions are taxed in the same manner as cash dividends and distributions — i.e., automatic reinvestment in additional shares does not relieve shareholders of, or defer the need to pay, any income tax that may be payable (or that is required to be withheld) on Fund dividends and distributions. The Funds and the Plan Agent reserve the right to amend or terminate the Plan. Additional information about the Plan, as well as a copy of the full Plan itself, may be obtained from the Plan Agent, Equiniti Trust Company, LLC, at P.O. Box 922, Wall Street Station, New York, NY 10269-0560; telephone number: (844) 33-PIMCO; www.astfinancial.com.

Additional Information Regarding the Funds

CHANGES OCCURRING DURING THE PRIOR FISCAL YEAR

The following information in this annual report is a summary of certain changes during the most recent fiscal year. This information may not reflect all of the changes that have occurred since you purchased shares of a Fund.

1. Effective December 22, 2022, the following non-fundamental guideline of the PIMCO High Income Fund was removed and, accordingly, disclosure was removed from the Fund’s registration statement and is not included in the “Use of Leverage” section of this annual report:

The Fund currently utilizes leverage principally through its outstanding auction rate preferred shares (“ARPS” and, together with any other preferred shares the Fund may have outstanding, “Preferred Shares”) and reverse repurchase agreements. The Fund may also obtain additional leverage through dollar rolls or borrowings, such as through bank loans or commercial paper and/or other credit facilities. The Fund will segregate liquid assets against or otherwise cover its future obligations under such transactions to the extent that, immediately after entering into such a transaction, the Fund’s future commitments that it has not segregated liquid assets against or otherwise covered, together with any outstanding Preferred Shares, would exceed 38% of the Fund’s total assets.

2. Effective December 27, 2022, the second paragraph of the “Principal Risks of the Fund — Additional Risks Associated with the Fund’s Preferred Shares” section of the Prospectus Summary and the second paragraph of the “Principal Risks of the Fund — Additional Risks Associated with the Fund’s Preferred Shares” section of the Prospectus for PIMCO Corporate & Income Strategy Fund were deleted and replaced with the following:

In addition, the multiple used to calculate the maximum applicable rate is based in part on the credit rating assigned to the ARPS by the applicable rating agency (currently, Moody’s and Fitch), with the multiple generally increasing as the rating declines below certain levels. In September 2011, Moody’s, a ratings agency that provides ratings for the Fund’s ARPS, downgraded its rating of the ARPS from “Aaa” to “Aa2,” citing what it believed to be persistently thin asset coverage levels, increased NAV volatility and concerns about secondary market liquidity for some assets supporting rated obligations. In July 2012, Moody’s downgraded its rating of the ARPS from “Aa2” to “Aa3” pursuant to a revised ratings methodology adopted by Moody’s. In May 2020, Fitch downgraded its rating of the ARPS from “AAA” to “AA,” indicating the downgrades reflected recent extreme market volatility and reduced asset liquidity, which it believed eroded asset coverage cushions for closed-end funds and challenged fund managers’ ability to deleverage. On December 4, 2020, Fitch published ratings criteria relating to closed-end fund obligations, including preferred shares, which effectively result in a rating cap of “AA” for debt and preferred stock issued by closed-end funds and a rating cap of “A” for (i) debt and preferred shares issued by closed-end funds exposed to corporate debt, emerging market debt, below-investment-grade and unrated debt, structured securities and equity, (ii) and closed-end funds with material exposure to “BBB” category rated assets. Following the close of business on April 30, 2021, Fitch downgraded its rating of the ARPS from “AA” to “A” pursuant to the revised ratings methodology and related new rating caps. Under the Bylaws, the April 2021 Fitch downgrade resulted in an increase in the multiple used to calculate the maximum applicable rate from 150% to 160%, thereby increasing the dividend rate payable to ARPS holders and increasing the expenses to Common Shareholders associated with the Fund’s leverage. In December 2022, Moody’s downgraded its rating of the ARPS from “Aa3” to “A1,” stating that the downgrades occurred because of, among other matters, trends in the Fund’s risk-adjusted asset coverage metrics and the evolution of its sector exposures. See “Use of Leverage” and “Description of Capital Structure.” It is possible for the ARPS to be further downgraded in the future, possibly resulting in further increases to the maximum applicable rate and, thereby, the expenses borne by the Fund’s Common Shareholders.

3. Effective December 27, 2022, the first and second paragraphs of the “Principal Risks of the Fund — Additional Risks Associated with the Fund’s Preferred Shares” section of the Prospectus Summary and the first and second paragraphs of the “Principal Risks of the Fund — Additional Risks Associated with the Fund’s Preferred Shares” section of the Prospectus for PIMCO Income Strategy Fund were deleted and replaced with the following:

Although the Fund’s ARPS ordinarily would pay dividends at rates set at periodic auctions, the weekly auctions for the ARPS (and auctions for similar preferred shares issued by closed-end funds in the U.S.) have failed since 2008. The dividend rates on the ARPS since that time have been paid, and the Fund expects that they will continue to be paid for the foreseeable future, at the “maximum applicable rate” under the Fund’s Bylaws (i.e., the greater of a multiple of or a spread plus a reference rate). An increase in market interest rates generally, therefore, could increase substantially the dividend rate required to be paid by the Fund to the holders of ARPS, which would increase the costs associated with the Fund’s leverage and reduce the Fund’s net income available for distribution to Common Shareholders.

In addition, the multiple used to calculate the maximum applicable rate is based in part on the credit rating assigned to the ARPS by the applicable rating agency (currently, Moody’s and Fitch), with the multiple generally increasing as the rating declines below certain levels. In September 2011, Moody’s, a ratings agency that provides ratings for the Fund’s ARPS, downgraded its rating of the ARPS from “Aaa” to “Aa2,” citing what it believed to be persistently thin asset coverage levels, increased NAV volatility and concerns about secondary market liquidity for some assets supporting rated obligations. Under the Bylaws, the 2011 Moody’s downgrade resulted in an increase in the dividend rate multiplier from 1.25 to 1.50, thereby increasing the dividend rate payable to ARPS holders and increasing the costs to Common Shareholders associated with the Fund’s leverage. See “Use of Leverage” and “Description of Capital Structure.” In July 2012, Moody’s downgraded its rating of the ARPS from “Aa2” to “Aa3” pursuant to a revised ratings methodology adopted by Moody’s. In May 2020, Fitch downgraded its rating of the ARPS from “AAA” to “AA,” indicating the downgrades reflected recent extreme market volatility and reduced asset liquidity, which it believed eroded asset coverage cushions for closed-end funds and challenged fund managers’ ability to deleverage. Under the Bylaws, the 2020 Fitch downgrade resulted in an increase in the applicable spread over the reference rate from 125 bps to 150 bps, thereby increasing the dividend rate payable to ARPS holders and increasing the costs to Common Shareholders associated with the Fund’s leverage. On December 4, 2020, Fitch published ratings criteria relating to closed-end fund obligations, including preferred shares, which effectively result in a rating cap of “AA” for debt and preferred stock issued by closed-end funds and a rating cap of “A” for (i) debt and preferred shares issued by closed-end funds exposed to corporate debt, emerging market debt, below-investment-grade and unrated debt, structured securities and equity, (ii) and closed-end funds with material exposure to “BBB” category rated assets. Following the close of business on April 30, 2021, Fitch downgraded its rating of the ARPS from “AA” to “A” pursuant to the revised ratings methodology and related new rating caps. Under the Bylaws, the April 2021 Fitch downgrade resulted in an increase in the dividend rate multiplier from 1.50 to 2.00, which could increase the dividend rate payable to ARPS holders should the maximum dividend rate be determined via the multiplier in lieu of the spread noted above (the maximum dividend rate is based on the greater of a multiple of or a spread plus

134 PIMCO CLOSED-END FUNDS

(Unaudited)

a reference rate) and, thereby, increase the expenses to Common Shareholders associated with the Fund’s leverage. In December 2022, Moody’s downgraded its rating of the ARPS from “Aa3” to “A1,” stating that the downgrades occurred because of, among other matters, trends in the Fund’s risk-adjusted asset coverage metrics and the evolution of its sector exposures. Under the Bylaws, the 2022 Moody’s downgrade resulted in an increase in the applicable spread over the reference rate from 150 bps to 200 bps. As noted herein, the maximum applicable rate actually payable to ARPS holders is based on the greater of a multiple of or a spread plus a reference rate, which is either the applicable Secured Overnight Funding Rate or the applicable Treasury Index Rate depending on the rate period. The applicable spread change resulting from the 2022 Moody’s downgrade will therefore impact the maximum applicable rate if the applicable spread formula is greater than the multiplier formula. See “Description of Capital Structure – Preferred Share Dividends.” See “Use of Leverage” and “Description of Capital Structure.” It is possible for the ARPS to be further downgraded in the future, possibly resulting in further increases to the maximum applicable rate and, thereby, the expenses borne by the Fund’s Common Shareholders.

4. Effective December 27, 2022, the second paragraph of the “Principal Risks of the Fund — Additional Risks Associated with the Fund’s Preferred Shares” section of the Prospectus Summary and the second paragraph of the “Principal Risks of the Fund — Additional Risks Associated with the Fund’s Preferred Shares” section of the Prospectus for PIMCO Income Strategy Fund II were deleted and replaced with the following:

The Funds’ Investment Objectives and Strategies

Unless otherwise noted, the information in this section is as of June 30, 2023.

The term “invest” includes both direct investing and indirect investing and the term “investments” includes both direct investments and indirect investments. For example, a Fund may invest indirectly by investing in derivatives or through wholly-owned subsidiaries (“Subsidiaries”), if applicable. The allocation of a Fund’s assets to a Subsidiary, if applicable, will vary over time and will likely not include all of the different types of investments described herein at any given time.

PIMCO Corporate & Income Opportunity Fund (“PTY”)

The Fund’s investment objective is to seek maximum total return through a combination of current income and capital appreciation.

The Fund seeks to achieve its investment objective by utilizing a dynamic asset allocation strategy among multiple fixed income sectors in the global credit markets, including corporate debt (including, among other things, fixed-, variable- and floating-rate bonds, loans (including, but not limited to, bank and/or other syndicated loans and non-syndicated (private direct) loans), convertible securities and stressed debt securities issued by U.S. or foreign (non-U.S.) corporations or other business entities, including emerging market issuers), mortgage-related and other asset-backed securities, government and sovereign debt, taxable municipal bonds and other fixed-, variable- and floating-rate income-producing securities of U.S. and foreign issuers, including emerging market issuers. The Fund may invest in investment grade debt securities and below investment grade debt securities (commonly referred to as “high yield” securities or “junk bonds”), including securities of stressed, distressed and defaulted issuers. The Fund cannot assure you that it will achieve its investment objective, and you could lose all of your investment in the Fund.

Portfolio Management Strategies

Dynamic Allocation Strategy.  In managing the Fund, the Fund’s investment manager, Pacific Investment Management Company LLC (“PIMCO” or the “Investment Manager”), employs an active approach to allocation among multiple fixed income sectors based on, among other things, market conditions, valuation assessments, economic outlook, credit market trends and other economic factors. With PIMCO’s macroeconomic analysis as the basis for top-down investment decisions, including geographic and credit sector emphasis, PIMCO manages the Fund with a focus on seeking income generating investment ideas across multiple fixed income sectors, with an emphasis on seeking opportunities in developed and emerging global credit markets. PIMCO may choose to focus on particular countries/regions, asset classes, industries and sectors to the exclusion of others

at any time and from time to time based on market conditions and other factors. The relative value assessment within fixed income sectors draws on PIMCO’s regional and sector specialist insights. The Fund will observe various investment guidelines as summarized below.

Investment Selection Strategies.  Once the Fund’s top-down, portfolio positioning decisions have been made as described above, PIMCO selects particular investments for the Fund by employing a bottom-up, disciplined credit approach which is driven by fundamental, independent research within each sector/asset class represented in the Fund, with a focus on identifying securities and other instruments with solid and/or improving fundamentals.

PIMCO utilizes strategies that focus on credit quality analysis, duration management and other risk management techniques. PIMCO attempts to identify, through fundamental research driven by independent credit analysis and proprietary analytical tools, debt obligations and other income-producing securities that provide current income and/or opportunities for capital appreciation based on its analysis of the issuer’s credit characteristics and the position of the security in the issuer’s capital structure.

Consideration of yield is only one component of the portfolio managers’ approach in managing the Fund. PIMCO also attempts to identify investments that may appreciate in value based on PIMCO’s assessment of the issuer’s credit characteristics, forecast for interest rates and outlook for particular countries/regions, currencies, industries, sectors and the global economy and bond markets generally.

Credit Quality.  The Fund may invest in debt instruments that are, at the time of purchase, rated below investment grade, or that are unrated but determined by PIMCO to be of comparable quality. The Fund will not normally invest more than 20% of its total assets in debt instruments, other than mortgage-related and other asset-backed securities, that are, at the time of purchase, rated CCC or lower by S&P Global Ratings (“S&P”) and Fitch, Inc. (“Fitch”) and Caa1 or lower by Moody’s Investors Services Inc. (“Moody’s”), or that are unrated but determined by PIMCO to be of comparable quality. The Fund may invest without limit in mortgage-related and other asset-backed securities regardless of rating (i.e., of any credit quality). Subject to this 20% restriction, the Fund may invest in issuers of any credit quality (including bonds in the lowest ratings categories). The Fund may also invest up to 5% of its total assets in defaulted bonds when PIMCO believes that the issuer’s potential revenues and prospects for recovery are favorable, except that the Fund may invest in mortgage-related and other asset-backed securities without regard to this limit, subject to the Fund’s other investment policies. For purposes of applying the foregoing policies, in the case of securities with split ratings (i.e., a security receiving two different ratings from two different rating agencies), the Fund will apply the higher of the

136 PIMCO CLOSED-END FUNDS

(Unaudited)

applicable ratings. Subject to the aforementioned investment restrictions, the Fund may invest in securities of stressed issuers, which include securities at risk of being in default as to the repayment of principal and/or interest at the time of acquisition by the Fund or that are rated in the lower rating categories by one or more nationally recognized statistical rating organizations (for example, Ca or lower by Moody’s or CC or lower by S&P or Fitch) or, if unrated, are determined by PIMCO to be of comparable quality. Debt instruments of below investment grade quality are regarded as having predominantly speculative characteristics with respect to capacity to pay interest and to repay principal, and are commonly referred to as “high yield” securities or “junk bonds.” Debt instruments in the lowest investment grade category also may be considered to possess some speculative characteristics. The Fund may, for hedging, investment or leveraging purposes, make use of credit default swaps, which are contracts whereby one party makes periodic payments to a counterparty in exchange for the right to receive from the counterparty a payment equal to the par (or other agreed-upon) value of a referenced debt obligation in the event of a default or other credit event by the issuer of the debt obligation.

Independent Credit Analysis.  PIMCO relies primarily on its own analysis of the credit quality and risks associated with individual debt instruments considered for the Fund, rather than relying exclusively on rating agencies or third-party research. The Fund’s portfolio managers utilize this information in an attempt to manage credit risk and/or to identify issuers, industries or sectors that are undervalued and/or offer attractive yields relative to PIMCO’s assessment of their credit characteristics. This aspect of PIMCO’s capabilities will be particularly important to the extent that the Fund invests in high yield securities and in securities of emerging market issuers.

Duration Management.  It is expected that the Fund normally will have a short to intermediate average portfolio duration (i.e., within a zero to eight year (0 to 8) range), as calculated by PIMCO, although it may be shorter or longer at any time or from time to time depending on market conditions and other factors. While the Fund seeks to maintain a short to intermediate average portfolio duration, there is no limit on the maturity or duration of any individual security in which the Fund may invest. Duration is a measure used to determine the sensitivity of a security’s price to changes in interest rates. The Fund’s duration strategy may entail maintaining a negative average portfolio duration from time to time, which would potentially benefit the portfolio in an environment of rising market interest rates, but would generally adversely impact the portfolio in an environment of falling or neutral market interest rates. The Fund may use various derivatives strategies to manage (increase or decrease) the dollar-weighted average effective duration of the Fund’s portfolio. PIMCO may also utilize certain strategies, including without limit investments in

structured notes or interest rate futures contracts or swap, cap, floor or collar transactions, for the purpose of reducing the interest rate sensitivity of the Fund’s portfolio, although there is no assurance that it will do so or that such strategies will be successful.

Portfolio Contents

Under normal market conditions, the Fund seeks to achieve its investment objective by investing at least 80% of its net assets plus borrowings for investment purposes in a combination of corporate debt obligations of varying maturities, other corporate income-producing securities, and income-producing securities of non-corporate issuers, such as U.S. Government securities, municipal securities and mortgage-backed and other asset-backed securities issued on a public or private basis (the “80% Policy”). The Fund’s investments in derivatives and other synthetic instruments that have economic characteristics similar to corporate debt obligations of varying maturities, other corporate income-producing securities, and income-producing securities of non-corporate issuers will be counted toward satisfaction of this 80% Policy. The Fund will normally invest at least 25% of its total assets in corporate debt obligations and other corporate income-producing securities. Corporate income-producing securities include fixed-, variable- and floating-rate bonds, debentures, notes and other similar types of corporate debt instruments, such as preferred shares, convertible securities, loans (including, but not limited to, bank and/or other syndicated loans and non-syndicated (private direct) loans) and loan participations and assignments, payment-in-kind securities, step-ups, zero-coupon bonds, bank capital securities, bank certificates of deposit, fixed time deposits and bankers’ acceptances, stressed debt securities, structured notes and other hybrid instruments. Certain corporate income-producing securities, such as convertible bonds, also may include the right to participate in equity appreciation, and PIMCO will generally evaluate those instruments based primarily on their debt characteristics. In satisfying the Fund’s 80% Policy, the Fund may invest in mortgage-related securities, including mortgage pass-through securities, collateralized mortgage obligations (“CMOs”), commercial or residential mortgage-backed securities, mortgage dollar rolls, CMO residuals, adjustable rate mortgage-backed securities, stripped mortgage-backed securities and other securities that directly or indirectly represent a participation in, or are secured by and payable from, mortgage loans on real property, debt instruments, including, without limitation, bonds, debentures, notes, and other debt securities of U.S. and foreign (non-U.S.) corporate and other issuers, including commercial paper; obligations of foreign governments or their sub-divisions, agencies and government sponsored enterprises and obligations of international agencies and supranational entities; municipal securities and other debt securities issued by states or local governments and their agencies, authorities and other government-sponsored enterprises, including taxable municipal securities (such as Build America Bonds);

The Funds’ Investment Objectives and Strategies (Cont.)

inflation-indexed bonds issued by both governments and corporations; structured notes, including hybrid or indexed securities; catastrophe bonds and other event-linked bonds; credit-linked notes; credit-linked trust certificates; structured credit products; loans (including, among others, senior loans, delayed funding loans, revolving credit facilities and loan participations and assignments); covenant-lite obligations; preferred securities and convertible debt securities (i.e., debt securities that may be converted at either a stated price or stated rate into underlying shares of common stock), including synthetic convertible debt securities (i.e., instruments created through a combination of separate securities that possess the two principal characteristics of a traditional convertible security, such as an income-producing security and the right to acquire an equity security) and contingent convertible securities. The Fund may invest in debt securities of stressed, distressed and defaulted issuers. Subject to the investment limitations described above, at any given time and from time to time, substantially all of the Fund’s portfolio may consist of below investment grade securities. The Fund may invest in various levels of the capital structure of an issuer of mortgage-backed or asset-backed securities (including collateralized bond obligations, collateralized loan obligations and other collateralized debt obligations), including the equity or “first loss” tranche. For the avoidance of doubt, equity or “first loss” tranches of mortgage-backed or asset-backed securities do not constitute equity interests for purposes of the Fund’s 20% limit on investments in equity interests described below. The Fund may also invest, as a third party purchaser, in risk retention tranches of CMBS or other eligible securitizations, which are eligible residual interests held by the sponsors of such securitizations pursuant to the final rules implementing the credit risk retention requirements of Section 941 of the Dodd-Frank Act. The rate of interest on an income-producing security may be fixed, floating or variable, and may move in the opposite direction to interest rates generally or the interest rate on another security or index (i.e., inverse floaters).

Subject to the limitations set forth in the Fund’s prospectus, including the limit on investments in emerging market securities and instruments, Fund may invest without limit in non-U.S. dollar denominated securities (of both developed and “emerging market” countries), including obligations of non-U.S. governments and their respective sub-divisions, agencies and government-sponsored enterprises. The Fund may invest without limit in investment grade sovereign debt denominated in the relevant country’s local currency with less than 1 year remaining to maturity (“short-term investment grade sovereign debt”), including short-term investment grade sovereign debt issued by emerging market issuers. The Fund may invest up to 40% of its total assets in securities and instruments that are economically tied to “emerging market” countries other than investments in short-term investment grade sovereign debt issued by emerging market issuers, where as noted above there is no limit. The Fund may also invest directly in foreign currencies, including local emerging market currencies.

The Fund may, but is not required to, utilize various derivative strategies (both long and short positions) involving the purchase or sale of futures and forward contracts (including foreign currency exchange contracts), call and put options, credit default swaps, total return swaps, basis swaps and other swap agreements and other derivative instruments for investment purposes, leveraging purposes or in an attempt to hedge against market, credit, interest rate, currency and other risks in the portfolio. The Fund may purchase and sell securities on a when-issued, delayed delivery or forward commitment basis and may engage in short sales.

The Fund may invest up to 20% of its total assets in common stocks and other equity securities from time to time, including those it has received through the conversion of a convertible security held by the Fund or in connection with the restructuring of a debt security. Common stocks include common shares and other common equity interest issued by public or private issuers.

The Fund may invest in securities that have not been registered for public sale in the U.S. or relevant non-U.S. jurisdictions, including without limit securities eligible for purchase and sale pursuant to Rule 144A under the Securities Act of 1933, or relevant provisions of applicable non-U.S. law, and other securities issued in private placements. The Fund may invest in securities of other open- or closed-end investment companies (including those advised by PIMCO), including, without limitation, exchange-traded funds (“ETFs”), to the extent that such investments are consistent with the Fund’s investment objectives, strategies and policies and permissible under the 1940 Act. The Fund may invest in other investment companies to gain broad market or sector exposure or for cash management purposes, including during periods when it has large amounts of uninvested cash or when PIMCO believes share prices of other investment companies offer attractive values. The Fund may invest in certain money market funds and/or short-term bond funds (“Central Funds”), to the extent permitted by the 1940 Act, the rules thereunder or exemptive relief therefrom. The Central Funds are registered investment companies created for use by certain registered investment companies advised by PIMCO in connection with their cash management activities. The Fund treats its investments in other investment companies that invest primarily in types of securities in which the Fund may invest directly as investments in such types of securities for purposes of the Fund’s investment policies (e.g., the Fund’s investment in an investment company that invests primarily in debt securities will be treated by the Fund as an investment in a debt security). As a shareholder in an investment company, the Fund would bear its ratable share of that investment company’s expenses and would remain subject to payment of the Fund’s management fees and other expenses with respect to assets so invested. Common Shareholders would therefore be subject to duplicative expenses to the extent the Fund invests in other

138 PIMCO CLOSED-END FUNDS

(Unaudited)

investment companies. The securities of other investment companies may be leveraged, in which case the NAV and/or market value of the investment company’s shares will be more volatile than unleveraged investments. The Fund may invest in real estate investment trusts. The Fund may invest in securities of companies with any market capitalization, including small and medium capitalizations.

The Fund may invest up to 20% of its total assets in illiquid securities (i.e., securities that the Fund reasonably expects cannot be sold or disposed of in current market conditions in seven calendar days or less without the sale or disposition significantly changing the market value of the security).

The Fund may enter into repurchase agreements, in which the Fund purchases a security from a bank or broker-dealer and the bank or broker-dealer agrees to repurchase the security at the Fund’s cost plus interest within a specified time.

The length of time the Fund has held a particular security is not generally a consideration in investment decisions. A change in the securities held by the Fund is known as “portfolio turnover.” The Fund may engage in frequent and active trading of portfolio securities to achieve its investment objective, particularly during periods of volatile market movements.

The Fund may lend its portfolio securities to brokers, dealers or other financial institutions provided a number of conditions are satisfied, including that the loan is fully collateralized.

There have been no significant changes in the Fund’s portfolio turnover rates over the last two fiscal years, and no significant change to the portfolio turnover rates of the Fund described in the Financial Highlights can currently be predicted.

In connection with rating the Fund’s outstanding auction rate preferred shares of beneficial interest (“ARPS” and, together with any other preferred shares the Fund may have outstanding, “Preferred Shares”), Moody’s imposes asset coverage tests and other restrictions that may limit the Fund’s ability to engage in certain of the transactions described above.

Temporary defensive investments.  The Fund may make short-term investments when attempting to respond to adverse market, economic, political, or other conditions, as determined by PIMCO. Upon PIMCO’s recommendation, for temporary defensive purposes and in order to keep the Fund’s cash fully invested, the Fund may deviate from its investment objective and policies and invest some or all of its net assets in investments of non-corporate issuers, including high quality, short-term debt securities. The Fund may not achieve its investment objective when it does so.

Use of Leverage

The Fund currently utilizes leverage principally through its outstanding Preferred Shares and reverse repurchase agreements and may also obtain additional leverage through dollar rolls or borrowings, such as through bank loans or commercial paper and/or other credit facilities. The amount of leverage the Fund utilizes may vary, but the Fund will not incur leverage (including Preferred Shares and other forms of leverage) in an amount exceeding 50% of its total assets.

The Fund may also enter into transactions other than those noted above that may give rise to a form of leverage including, among others, futures and forward contracts (including foreign currency exchange contracts), total return swaps and other derivative transactions, loans of portfolio securities, short sales, when-issued, delayed delivery and forward commitment transactions and selling credit default swaps. The Fund may also determine to issue other types of preferred shares. Leveraging transactions pursued by the Fund may increase its duration and sensitivity to interest rate movements.

The Fund utilizes certain kinds of leverage, such as reverse repurchase agreements and selling credit default swaps, opportunistically and may choose to increase or decrease, or eliminate entirely, its use of such leverage over time and from time to time based on PIMCO’s assessment of the yield curve environment, interest rate trends, market conditions and other factors. The Fund may also determine to decrease the leverage it currently maintains through its outstanding Preferred Shares through Preferred Shares redemptions or tender offers and may or may not determine to replace such leverage through other sources.

The Fund also may borrow money for temporary purposes, to add leverage to the portfolio or for the settlement of securities transactions which otherwise might require untimely dispositions of portfolio securities held by the Fund.

PIMCO Corporate & Income Strategy Fund (“PCN”)

The Fund’s primary investment objective is to seek high current income, with secondary objectives of capital preservation and appreciation.

The Fund seeks to achieve its investment objectives by utilizing a dynamic asset allocation strategy among multiple fixed income sectors in the global credit markets, including corporate debt (including, among other things, fixed-, variable- and floating-rate bonds, loans (including, but not limited to, bank and/or other syndicated loans and non-syndicated (private direct) loans), convertible securities and stressed debt securities issued by U.S. or foreign (non-U.S.) corporations or other business entities, including emerging market issuers), mortgage-related and other asset-backed securities, government and sovereign debt, taxable municipal bonds and other fixed-, variable- and floating-rate income-producing securities of U.S.

and foreign issuers, including emerging market issuers. The Fund may invest in investment grade debt securities and below investment grade debt securities (commonly referred to as “high yield” securities or “junk bonds”), including securities of stressed, distressed and defaulted issuers. The Fund cannot assure you that it will achieve its investment objectives, and you could lose all of your investment in the Fund.

Portfolio Management Strategies

Dynamic Allocation Strategy.  In managing the Fund, the Fund’s investment manager, PIMCO employs an active approach to allocation among multiple fixed income sectors based on, among other things, market conditions, valuation assessments, economic outlook, credit market trends and other economic factors. With PIMCO’s macroeconomic analysis as the basis for top-down investment decisions, including geographic and credit sector emphasis, PIMCO manages the Fund with a focus on seeking income generating investment ideas across multiple fixed income sectors, with an emphasis on seeking opportunities in developed and emerging global credit markets. PIMCO may choose to focus on particular countries/regions, asset classes, industries and sectors to the exclusion of others at any time and from time to time based on market conditions and other factors. For example, subject to the Fund’s investment policies and limitations, the Fund may invest a substantial portion of its total assets in mortgage-related and other asset-backed securities, which investments PIMCO may choose to increase or decrease, or eliminate entirely, over time and from time to time. The relative value assessment within fixed income sectors draws on PIMCO’s regional and sector specialist insights. The Fund will observe various investment guidelines as summarized below.

Investment Selection Strategies.  Once the Fund’s top-down, portfolio positioning decisions have been made as described above, PIMCO selects particular investments for the Fund by employing a bottom-up, disciplined credit approach which is driven by fundamental, independent research within each sector/asset class represented in the Fund, with a focus on identifying securities and other instruments with solid and/or improving fundamentals.

PIMCO utilizes strategies that focus on credit quality analysis, duration management and other risk management techniques. PIMCO attempts to identify, through fundamental research driven by independent credit analysis and proprietary analytical tools, debt obligations and other income-producing securities that provide current income and/or opportunities for capital appreciation based on its analysis of the issuer’s credit characteristics and the position of the security in the issuer’s capital structure.

Consideration of yield is only one component of the portfolio managers’ approach in managing the Fund. PIMCO also attempts to identify investments that may appreciate in value based on PIMCO’s assessment

of the issuer’s credit characteristics, forecast for interest rates and outlook for particular countries/regions, currencies, industries, sectors and the global economy and bond markets generally.

Credit Quality.  The Fund may invest in debt instruments that are, at the time of purchase, rated below investment grade, or that are unrated but determined by PIMCO to be of comparable quality. The Fund will not normally invest more than 20% of its total assets in debt instruments, other than mortgage-related and other asset-backed securities, that are, at the time of purchase, rated CCC or lower by S&P and Fitch and Caa1 or lower by Moody’s, or that are unrated but determined by PIMCO to be of comparable quality. The Fund may invest without limit in mortgage-related and other asset-backed securities regardless of rating (i.e., of any credit quality). Subject to this 20% restriction, the Fund may invest in issuers of any credit quality (including bonds in the lowest ratings categories). The Fund may also invest up to 5% of its total assets in defaulted bonds when PIMCO believes that the issuer’s potential revenues and prospects for recovery are favorable, except that the Fund may invest in mortgage-related and other asset-backed securities without regard to this limit, subject to the Fund’s other investment policies. For purposes of applying the foregoing policies, in the case of securities with split ratings (i.e., a security receiving two different ratings from two different rating agencies), the Fund will apply the higher of the applicable ratings. Subject to the aforementioned investment restrictions, the Fund may invest in securities of stressed issuers, which include securities at risk of being in default as to the repayment of principal and/or interest at the time of acquisition by the Fund or that are rated in the lower rating categories by one or more nationally recognized statistical rating organizations (for example, Ca or lower by Moody’s or CC or lower by S&P or Fitch) or, if unrated, are determined by PIMCO to be of comparable quality. Debt instruments of below investment grade quality are regarded as having predominantly speculative characteristics with respect to capacity to pay interest and to repay principal, and are commonly referred to as “high yield” securities or “junk bonds.” Debt instruments in the lowest investment grade category also may be considered to possess some speculative characteristics. The Fund may, for hedging, investment or leveraging purposes, make use of credit default swaps, which are contracts whereby one party makes periodic payments to a counterparty in exchange for the right to receive from the counterparty a payment equal to the par (or other agreed-upon) value of a referenced debt obligation in the event of a default or other credit event by the issuer of the debt obligation.

Independent Credit Analysis.  PIMCO relies primarily on its own analysis of the credit quality and risks associated with individual debt instruments considered for the Fund, rather than relying exclusively on rating agencies or third-party research. The Fund’s portfolio managers

140 PIMCO CLOSED-END FUNDS

(Unaudited)

utilize this information in an attempt to manage credit risk and/or to identify issuers, industries and/or sectors that are undervalued or that offer attractive yields relative to PIMCO’s assessment of their credit characteristics. This aspect of PIMCO’s capabilities will be particularly important to the extent that the Fund invests in high yield securities and in securities of emerging market issuers.

Duration Management.  It is expected that the Fund normally will have a short to intermediate average portfolio duration (i.e., within a zero to eight (0 to 8) year range), as calculated by PIMCO, although it may be shorter or longer at any time or from time to time depending on market conditions and other factors. While the Fund seeks to maintain a short to intermediate average portfolio duration, there is no limit on the maturity or duration of any individual security in which the Fund may invest. Duration is a measure used to determine the sensitivity of a security’s price to changes in interest rates. The Fund’s duration strategy may entail maintaining a negative average portfolio duration from time to time, which would potentially benefit the portfolio in an environment of rising market interest rates, but would generally adversely impact the portfolio in an environment of falling or neutral market interest rates. The Fund may use various derivatives strategies to manage (increase or decrease) the dollar-weighted average effective duration of the Fund’s portfolio. PIMCO may also utilize certain strategies, including without limit investments in structured notes or interest rate futures contracts or swap, cap, floor or collar transactions, for the purpose of reducing the interest rate sensitivity of the Fund’s portfolio, although there is no assurance that it will do so or that such strategies will be successful.

Portfolio Contents

Under normal market conditions, the Fund seeks to achieve its investment objectives by investing at least 80% of its net assets plus borrowings for investment purposes in a combination of corporate debt obligations of varying maturities, other corporate income-producing securities, and income-producing securities of non-corporate issuers, such as U.S. Government securities, municipal securities and mortgage-backed and other asset-backed securities issued on a public or private basis (the “80% Policy”). The Fund’s investments in derivatives and other synthetic instruments that have economic characteristics similar to corporate debt obligations of varying maturities, other corporate income-producing securities, and income-producing securities of non-corporate issuers will be counted toward satisfaction of this 80% Policy. The Fund will normally invest at least 25% of its total assets in corporate debt obligations and other corporate income-producing securities. Corporate income-producing securities include fixed-, variable- and floating-rate bonds, debentures, notes and other similar types of corporate debt instruments, such as preferred shares, convertible securities, loans (including, but not

limited to, bank and/or other syndicated loans and non-syndicated (private direct) loans) and loan participations and assignments, payment-in-kind securities, step-ups, zero-coupon bonds, bank capital securities, bank certificates of deposit, fixed time deposits and bankers’ acceptances, stressed debt securities, structured notes and other hybrid instruments. Certain corporate income-producing securities, such as convertible bonds, also may include the right to participate in equity appreciation, and PIMCO will generally evaluate those instruments based primarily on their debt characteristics. In satisfying the Fund’s 80% Policy, the Fund may invest in mortgage-related securities, including mortgage pass-through securities, collateralized mortgage obligations (“CMOs”), commercial or residential mortgage-backed securities, mortgage dollar rolls, CMO residuals, adjustable rate mortgage-backed securities, stripped mortgage-backed securities and other securities that directly or indirectly represent a participation in, or are secured by and payable from, mortgage loans on real property, debt instruments, including, without limitation, bonds, debentures, notes, and other debt securities of U.S. and foreign (non-U.S.) corporate and other issuers, including commercial paper; obligations of foreign governments or their sub-divisions, agencies and government sponsored enterprises and obligations of international agencies and supranational entities; municipal securities and other debt securities issued by states or local governments and their agencies, authorities and other government-sponsored enterprises, including taxable municipal securities (such as Build America Bonds); inflation-indexed bonds issued by both governments and corporations; structured notes, including hybrid or indexed securities; catastrophe bonds and other event-linked bonds; credit-linked notes; credit-linked trust certificates; structured credit products; loans (including, among others, senior loans, delayed funding loans, revolving credit facilities and loan participations and assignments); covenant-lite obligations; preferred securities and convertible debt securities (i.e., debt securities that may be converted at either a stated price or stated rate into underlying shares of common stock), including synthetic convertible debt securities (i.e., instruments created through a combination of separate securities that possess the two principal characteristics of a traditional convertible security, such as an income-producing security and the right to acquire an equity security) and contingent convertible securities. The Fund may invest in debt securities of stressed, distressed and defaulted issuers. Subject to the investment limitations described above, at any given time and from time to time, substantially all of the Fund’s portfolio may consist of below investment grade securities. The Fund may invest in various levels of the capital structure of an issuer of mortgage-backed or asset-backed securities (including collateralized bond obligations, collateralized loan obligations and other collateralized debt obligations), including the equity or “first loss” tranche. For the avoidance of doubt, equity or “first loss” tranches of mortgage-backed or asset-backed securities do not constitute equity interests for purposes of the Fund’s 20% limit on

ANNUAL REPORT | JUNE 30, 2023 141

investments in equity interests described below. The Fund may also invest, as a third party purchaser, in risk retention tranches of CMBS or other eligible securitizations, which are eligible residual interests held by the sponsors of such securitizations pursuant to the final rules implementing the credit risk retention requirements of Section 941 of the Dodd-Frank Act. The rate of interest on an income-producing security may be fixed, floating or variable, and may move in the opposite direction to interest rates generally or the interest rate on another security or index (i.e., inverse floaters).

Subject to the limitations set forth in the Fund’s prospectus, including the limit on investments in emerging market securities and instruments, the Fund may invest without limit in non-U.S. dollar denominated securities (of both developed and “emerging market” countries), including obligations of non-U.S. governments and their respective sub-divisions, agencies and government-sponsored enterprises. The Fund may invest without limit in investment grade sovereign debt denominated in the relevant country’s local currency with less than 1 year remaining to maturity (“short-term investment grade sovereign debt”), including short-term investment grade sovereign debt issued by emerging market issuers. The Fund may invest up to 40% of its total assets in securities and instruments that are economically tied to “emerging market” countries other than investments in short-term investment grade sovereign debt issued by emerging market issuers, where as noted above there is no limit. The Fund may also invest directly in foreign currencies, including local emerging market currencies.

The Fund may, but is not required to, utilize various derivative strategies (both long and short positions) involving the purchase or sale of futures and forward contracts (including foreign currency exchange contracts), call and put options, credit default swaps, total return swaps, basis swaps and other swap agreements and other derivative instruments for investment purposes, leveraging purposes or in an attempt to hedge against market, credit, interest rate, currency and other risks in the portfolio. The Fund may purchase and sell securities on a when-issued, delayed delivery or forward commitment basis and may engage in short sales.

The Fund may invest up to 20% of its total assets in common stocks and other equity securities from time to time, including those it has received through the conversion of a convertible security held by the Fund or in connection with the restructuring of a debt security.

Common stocks include common shares and other common equity interest issued by public or private issuers.

The Fund may invest in securities that have not been registered for public sale in the U.S. or relevant non-U.S. jurisdictions, including without limit securities eligible for purchase and sale pursuant to Rule 144A under the Securities Act of 1933, or relevant provisions of

applicable non-U.S. law, and other securities issued in private placements. The Fund may invest in securities of other open- or closed-end investment companies (including those advised by PIMCO), including, without limitation, ETFs, to the extent that such investments are consistent with the Fund’s investment objectives, strategies and policies and permissible under the 1940 Act. The Fund may invest in other investment companies to gain broad market or sector exposure or for cash management purposes, including during periods when it has large amounts of uninvested cash or when PIMCO believes share prices of other investment companies offer attractive values. The Fund may invest in certain money market funds and/or short-term bond funds (“Central Funds”), to the extent permitted by the 1940 Act, the rules thereunder or exemptive relief therefrom. The Central Funds are registered investment companies created for use by certain registered investment companies advised by PIMCO in connection with their cash management activities. The Fund treats its investments in other investment companies that invest primarily in types of securities in which the Fund may invest directly as investments in such types of securities for purposes of the Fund’s investment policies (e.g., the Fund’s investment in an investment company that invests primarily in debt securities will be treated by the Fund as an investment in a debt security). As a shareholder in an investment company, the Fund would bear its ratable share of that investment company’s expenses and would remain subject to payment of the Fund’s management fees and other expenses with respect to assets so invested. Common Shareholders would therefore be subject to duplicative expenses to the extent the Fund invests in other investment companies. The securities of other investment companies may be leveraged, in which case the NAV and/or market value of the investment company’s shares will be more volatile than unleveraged investments. The Fund may invest in real estate investment trusts. The Fund may invest in securities of companies with any market capitalization, including small and medium capitalizations.

The Fund may invest up to 15% of its total assets in illiquid investments (i.e., investments that the Fund reasonably expects cannot be sold or disposed of in current market conditions in seven calendar days or less without the sale or disposition significantly changing the market value of the security).

The Fund may enter into repurchase agreements, in which the Fund purchases a security from a bank or broker-dealer and the bank or broker-dealer agrees to repurchase the security at the Fund’s cost plus interest within a specified time.

The Fund may lend its portfolio securities to brokers, dealers or other financial institutions provided a number of conditions are satisfied, including that the loan is fully collateralized.

142 PIMCO CLOSED-END FUNDS

(Unaudited)

The length of time the Fund has held a particular security is not generally a consideration in investment decisions. A change in the securities held by the Fund is known as “portfolio turnover.” The Fund may engage in frequent and active trading of portfolio securities to achieve its investment objectives, particularly during periods of volatile market movements.

There have been no significant changes in the Fund’s portfolio turnover rates over the last two fiscal years, and no significant change to the portfolio turnover rates of the Fund described in the Financial Highlights can currently be predicted.

In connection with rating the Fund’s outstanding auction rate preferred shares of beneficial interest (“ARPS” and, together with any other preferred shares the Fund may have outstanding, “Preferred Shares”), Moody’s and Fitch impose asset coverage tests and other restrictions that may limit the Fund’s ability to engage in certain of the transactions described above.

Temporary defensive investments.  The Fund may make short-term investments when attempting to respond to adverse market, economic, political, or other conditions, as determined by PIMCO. Upon PIMCO’s recommendation, for temporary defensive purposes and in order to keep the Fund’s cash fully invested, the Fund may deviate from its investment objectives and policies and invest some or all of its net assets in investments of non-corporate issuers, including high quality, short-term debt securities. The Fund may not achieve its investment objectives when it does so.

Use of Leverage

The Fund currently utilizes leverage principally through its outstanding Preferred Shares and reverse repurchase agreements and may also obtain additional leverage through dollar rolls or borrowings, such as through bank loans or commercial paper and/or other credit facilities. The amount of leverage the Fund utilizes may vary but total leverage resulting from the issuance of Preferred Shares and senior securities representing indebtedness of the Fund will not exceed 50% of the Fund’s total assets less all liabilities and indebtedness not represented by senior securities.

The Fund may also enter into transactions other than those noted above that may give rise to a form of leverage including, among others, selling credit default swaps, futures and forward contracts (including foreign currency exchange contracts), total return swaps and other derivative transactions, loans of portfolio securities, short sales and when-issued, delayed delivery and forward commitment transactions. The Fund may also determine to issue other types of preferred shares. Depending upon market conditions and other factors, the Fund may or may not determine to add leverage following an offering to maintain or increase the total amount of leverage (as a

percentage of the Fund’s total assets) that the Fund currently maintains immediately prior to an offering, taking into account the additional assets raised through the issuance of Common Shares in such offering. Leveraging transactions pursued by the Fund may increase its duration and sensitivity to interest rate movements.

The Fund utilizes certain kinds of leverage, such as reverse repurchase agreements and credit default swaps, opportunistically and may choose to increase or decrease, or eliminate entirely, its use of such leverage over time and from time to time based on PIMCO’s assessment of the yield curve environment, interest rate trends, market conditions and other factors. The Fund may also determine to decrease the leverage it currently maintains through its outstanding Preferred Shares through Preferred Shares redemptions or tender offers and may or may not determine to replace such leverage through other sources.

The Fund also may borrow money for temporary purposes, to add leverage to the portfolio or for the settlement of securities transactions which otherwise might require untimely dispositions of portfolio securities held by the Fund.

PIMCO High Income Fund (“PHK”)

The Fund’s primary investment objective is to seek high current income, with capital appreciation as a secondary objective.

The Fund seeks to achieve its investment objectives by utilizing a dynamic asset allocation strategy among multiple fixed income sectors in the global credit markets, which may include corporate debt (including, among other things, fixed-, variable- and floating-rate bonds, loans (including, but not limited to, bank and/or other syndicated loans and non-syndicated (private direct) loans), convertible securities and stressed debt securities issued by U.S. or foreign (non-U.S.) corporations or other business entities, including emerging market issuers), mortgage-related and other asset-backed securities, government and sovereign debt, taxable municipal bonds and other fixed-, variable- and floating-rate income-producing securities of U.S. and foreign issuers, including emerging market issuers. Aiming to identify securities that provide high current income and/or capital appreciation, the Fund focuses on duration management, credit quality analysis, risk management techniques and broad diversification among issuers, industries and sectors as well as other risk management techniques designed to manage default risk. The Fund may invest in investment grade debt securities and below investment grade debt securities (commonly referred to as “high yield” securities or “junk bonds”), including securities of stressed, distressed and defaulted issuers. The Fund cannot assure you that it will achieve its investment objectives, and you could lose all of your investment in the Fund.

The Funds’ Investment Objectives and Strategies (Cont.)

Portfolio Management Strategies

Dynamic Allocation Strategy.  In managing the Fund, the Fund’s investment manager, PIMCO, employs an active approach to allocation among multiple fixed income sectors based on, among other things, market conditions, valuation assessments, economic outlook, credit market trends and other economic factors. With PIMCO’s macroeconomic analysis as the basis for top-down investment decisions, including geographic and credit sector emphasis, PIMCO manages the Fund with a focus on seeking income generating investment ideas across multiple fixed income sectors, with an emphasis on seeking opportunities in developed and emerging global credit markets. PIMCO may choose to focus on particular countries/regions, asset classes, industries and sectors to the exclusion of others at any time and from time to time based on market conditions and other factors. The relative value assessment within fixed income sectors draws on PIMCO’s regional and sector specialist insights. The Fund will observe various investment guidelines as summarized below.

Investment Selection Strategies.  Once the Fund’s top-down, portfolio positioning decisions have been made as described above, PIMCO selects particular investments for the Fund by employing a bottom-up, disciplined credit approach which is driven by fundamental, independent research within each sector/asset class represented in the Fund, with a focus on identifying securities and other instruments with solid and/or improving fundamentals.

PIMCO utilizes strategies that focus on credit quality analysis, duration management and other risk management techniques. PIMCO attempts to identify, through fundamental research driven by independent credit analysis and proprietary analytical tools, debt obligations and other income-producing securities that provide current income and/or opportunities for capital appreciation based on its analysis of the issuer’s credit characteristics and the position of the security in the issuer’s capital structure.

Consideration of yield is only one component of the portfolio managers’ approach in managing the Fund. PIMCO also attempts to identify investments that may appreciate in value based on PIMCO’s assessment of the issuer’s credit characteristics, forecast for interest rates and outlook for particular countries/regions, currencies, industries, sectors and the global economy and bond markets generally.

Credit Quality.  The Fund may invest in debt instruments that are, at the time of purchase, rated below investment grade, or that are unrated but determined by PIMCO to be of comparable quality. The Fund will not normally invest more than 20% of its total assets in debt instruments, other than mortgage-related and other asset-backed securities, that are, at the time of purchase, rated CCC or lower by S&P and Fitch and Caa1 or lower by Moody’s, or that are unrated but determined by PIMCO to be of comparable quality. The Fund may

invest without limit in mortgage-related and other asset-backed securities regardless of rating (i.e., of any credit quality). Subject to this 20% restriction, the Fund may invest any portion of its assets (or none) in issuers of any credit quality (including bonds in the lowest ratings categories). For purposes of applying the foregoing policies, in the case of securities with split ratings (i.e., a security receiving two different ratings from two different rating agencies), the Fund will apply the higher of the applicable ratings. Subject to the aforementioned investment restrictions, the Fund may invest in securities of stressed issuers, which include securities at risk of being in default as to the repayment of principal and/or interest at the time of acquisition by the Fund or that are rated in the lower rating categories by one or more nationally recognized statistical rating organizations (for example, Ca or lower by Moody’s or CC or lower by S&P or Fitch) or, if unrated, are determined by PIMCO to be of comparable quality. Debt instruments of below investment grade quality are regarded as having predominantly speculative characteristics with respect to capacity to pay interest and to repay principal, and are commonly referred to as “high yield” securities or “junk bonds.” Debt instruments in the lowest investment grade category also may be considered to possess some speculative characteristics. The Fund may, for hedging, investment or leveraging purposes, make use of credit default swaps, which are contracts whereby one party makes periodic payments to a counterparty in exchange for the right to receive from the counterparty a payment equal to the par (or other agreed-upon) value of a referenced debt obligation in the event of a default or other credit event by the issuer of the debt obligation.

Independent Credit Analysis.  PIMCO relies primarily on its own analysis of the credit quality and risks associated with individual debt instruments considered for the Fund, rather than relying exclusively on rating agencies or third-party research. The Fund’s portfolio managers utilize this information in an attempt to manage credit risk and/or to identify issuers, industries or sectors that are undervalued and/or offer attractive yields relative to PIMCO’s assessment of their credit characteristics. This aspect of PIMCO’s capabilities will be particularly important to the extent that the Fund invests in high yield securities and in securities of emerging market issuers.

Duration Management.  It is expected that the Fund normally will have a short to intermediate average portfolio duration (i.e., within a zero to eight year (0 to 8) range), as calculated by PIMCO, although it may be shorter or longer at any time or from time to time depending on market conditions and other factors. While the Fund seeks to maintain a short to intermediate average portfolio duration, there is no limit on the maturity or duration of any individual security in which the Fund may invest. Duration is a measure used to determine the sensitivity of a security’s price to changes in interest rates. The Fund’s

144 PIMCO CLOSED-END FUNDS

(Unaudited)

duration strategy may entail maintaining a negative average portfolio duration from time to time, meaning the portfolio would tend to increase in value in response to an increase in interest rates. If the Fund has a negative average portfolio duration, a 1% increase in interest rates would tend to correspond to a 1% increase in the value of the Fund’s debt portfolio for every year of negative duration. A negative average portfolio duration would potentially benefit the portfolio in an environment of rising market interest rates, but would generally adversely impact the portfolio in an environment of falling or neutral market interest rates. The Fund may use various derivatives strategies to manage (increase or decrease) the dollar-weighted average effective duration of the Fund’s portfolio. PIMCO may also utilize certain strategies, including without limitation investments in structured notes or interest rate futures contracts or swap, cap, floor or collar transactions, for the purpose of reducing the interest rate sensitivity of the Fund’s portfolio, although there is no assurance that it will do so or that such strategies will be successful.

Portfolio Contents

Under normal market conditions, the Fund seeks to achieve its investment objectives by investing in, among other things, a combination of corporate debt obligations of varying maturities, other corporate income-producing securities, and income-producing securities of non-corporate issuers, such as U.S. Government securities, municipal securities and mortgage-backed and other asset-backed securities issued on a public or private basis. Corporate-income producing securities may include fixed-, variable- and floating-rate bonds, debentures, notes and other similar types of corporate debt instruments, such as preferred shares, convertible securities, loans (including, but not limited to, bank and/or other syndicated loans and non-syndicated (private direct) loans) and loan participations and assignments, payment-in-kind securities, step-ups, zero-coupon bonds, bank certificates of deposit, fixed time deposits and bankers’ acceptances, stressed debt securities, structured notes and other hybrid instruments. Certain corporate income-producing securities, such as convertible bonds, also may include the right to participate in equity appreciation, and PIMCO will generally evaluate those instruments based primarily on their debt characteristics. The Fund may invest in mortgage-related securities, including mortgage pass-through securities, collateralized mortgage obligations (“CMOs”), commercial or residential mortgage-backed securities, mortgage dollar rolls/buy backs, CMO residuals, adjustable rate mortgage-backed securities, stripped mortgage-backed securities and other securities that directly or indirectly represent a participation in, or are secured by and payable from, mortgage loans on real property, debt instruments, including, without limitation, bonds, debentures, notes, and other debt securities of U.S. and foreign (non-U.S.) corporate and other issuers, including commercial paper; obligations of foreign governments or their sub-divisions, agencies and government sponsored enterprises and

obligations of international agencies and supranational entities; municipal securities and other debt securities issued by states or local governments and their agencies, authorities and other government-sponsored enterprises, including taxable municipal securities (such as Build America Bonds); inflation-indexed bonds issued by both governments and corporations; structured notes, including hybrid or indexed securities; catastrophe bonds and other event-linked bonds; credit-linked notes; credit-linked trust certificates; structured credit products; loans (including, among others, senior loans, delayed funding loans, revolving credit facilities and loan participations and assignments); covenant-lite obligations; preferred securities and convertible debt securities (i.e., debt securities that may be converted at either a stated price or stated rate into underlying shares of common stock), including synthetic convertible debt securities (i.e., instruments created through a combination of separate securities that possess the two principal characteristics of a traditional convertible security, such as an income-producing security and the right to acquire an equity security) and contingent convertible securities. The Fund may invest in debt securities of stressed, distressed and defaulted issuers. Subject to the investment limitations described above, at any given time and from time to time, substantially all of the Fund’s portfolio may consist of below investment grade securities. The Fund may invest in various levels of the capital structure of an issuer of mortgage-backed or asset-backed securities (including collateralized bond obligations, collateralized loan obligations and other collateralized debt obligations), including the equity or “first loss” tranche. For the avoidance of doubt, equity or “first loss” tranches of mortgage-backed or asset-backed securities do not constitute equity interests for purposes of the Fund’s 20% limit on investments in equity interests described below. The Fund may also invest, as a third party purchaser, in risk retention tranches of CMBS or other eligible securitizations, which are eligible residual interests held by the sponsors of such securitizations pursuant to the final rules implementing the credit risk retention requirements of Section 941 of the Dodd-Frank Act. The rate of interest on an income-producing security may be fixed, floating or variable, and may move in the opposite direction to interest rates generally or the interest rate on another security or index (i.e., inverse floaters).

Subject to the limitations set forth in the Fund’s prospectus, the Fund may invest in non-U.S. dollar denominated securities (of both developed and “emerging market” countries), including obligations of non-U.S. governments and their respective sub-divisions, agencies and government-sponsored enterprises. The Fund may invest without limit in investment grade sovereign debt denominated in the relevant country’s local currency with less than 1 year remaining to maturity (“short-term investment grade sovereign debt”), including short-term investment grade sovereign debt issued by emerging market issuers. The Fund may invest up to 40% of its total assets in securities and

ANNUAL REPORT | JUNE 30, 2023 145

The Funds’ Investment Objectives and Strategies (Cont.)

instruments that are economically tied to “emerging market” countries other than investments in short-term investment grade sovereign debt issued by emerging market issuers, where as noted above there is no limit. The Fund may also invest directly in foreign currencies, including local emerging market currencies.

The Fund may, but is not required to, utilize various derivative strategies (both long and short positions) involving the purchase or sale of futures and forward contracts (including foreign currency exchange contracts), call and put options, credit default swaps, total return swaps, basis swaps and other swap agreements and other derivative instruments for investment purposes, leveraging purposes or in an attempt to hedge against market, credit, interest rate, currency and other risks in the portfolio. The Fund may purchase and sell securities on a when-issued, delayed delivery or forward commitment basis and may engage in short sales.

The Fund may invest up to 20% of its total assets in common stocks and other equity securities from time to time, including those it has received through the conversion of a convertible security held by the Fund or in connection with the restructuring of a debt security. Common stocks include common shares and other common equity interest issued by public or private issuers. The Fund may invest up to 20% of its total assets in bank loans.

The Fund may invest in securities that have not been registered for public sale in the U.S. or relevant non-U.S. jurisdictions, including without limit securities eligible for purchase and sale pursuant to Rule 144A under the Securities Act of 1933, or relevant provisions of applicable non-U.S. law, and other securities issued in private placements. The Fund may invest in securities of other open- or closed-end investment companies (including those advised by PIMCO), including, without limitation, ETFs, to the extent that such investments are consistent with the Fund’s investment objectives, strategies and policies and permissible under the 1940 Act. The Fund may invest in other investment companies to gain broad market or sector exposure or for cash management purposes, including during periods when it has large amounts of uninvested cash or when PIMCO believes share prices of other investment companies offer attractive values. The Fund may invest in certain money market funds and/or short-term bond funds (“Central Funds”), to the extent permitted by the 1940 Act, the rules thereunder or exemptive relief therefrom. The Central Funds are registered investment companies created for use by certain registered investment companies advised by PIMCO in connection with their cash management activities. The Fund treats its investments in other investment companies that invest primarily in types of securities in which the Fund may invest directly as investments in such types of securities for purposes of the Fund’s investment policies (e.g., the Fund’s investment in an investment company that invests primarily in

debt securities will be treated by the Fund as an investment in a debt security). As a shareholder in an investment company, the Fund would bear its ratable share of that investment company’s expenses and would remain subject to payment of the Fund’s management fees and other expenses with respect to assets so invested. Common Shareholders would therefore be subject to duplicative expenses to the extent the Fund invests in other investment companies. The securities of other investment companies may be leveraged, in which case the NAV and/or market value of the investment company’s shares will be more volatile than unleveraged investments.

The Fund may invest in real estate investment trusts. The Fund may invest in securities of companies with any market capitalization, including small and medium capitalizations.

The Fund may enter into repurchase agreements, in which the Fund purchases a security from a bank or broker-dealer and the bank or broker-dealer agrees to repurchase the security at the Fund’s cost plus interest within a specified time.

The Fund may lend its portfolio securities to brokers, dealers or other financial institutions provided a number of conditions are satisfied, including that the loan is fully collateralized.

The Fund may invest without limitation in illiquid investments (i.e., investments that the Fund reasonably expects cannot be sold or disposed of in current market conditions in seven calendar days or less without the sale or disposition significantly changing the market value of the investment).

The length of time the Fund has held a particular security is not generally a consideration in investment decisions. A change in the securities held by the Fund is known as “portfolio turnover.” The Fund may engage in frequent and active trading of portfolio securities to achieve its investment objectives, particularly during periods of volatile market movements.

There have been no significant changes in the Fund’s portfolio turnover rates over the last two fiscal years, and no significant change to the portfolio turnover rates of the Fund described in the Financial Highlights can currently be predicted.

In connection with rating the Fund’s outstanding auction rate preferred shares of beneficial interest (“ARPS” and, together with any other preferred shares the Fund may have outstanding, “Preferred Shares”), Moody’s and Fitch impose asset coverage tests and other restrictions that may limit the Fund’s ability to engage in certain of the transactions described above.

Temporary defensive investments.  The Fund may make short-term investments when attempting to respond to adverse market, economic, political, or other conditions, as determined by PIMCO.

146 PIMCO CLOSED-END FUNDS

(Unaudited)

Upon PIMCO’s recommendation, for temporary defensive purposes and in order to keep the Fund’s cash fully invested, the Fund may deviate from its investment objectives and policies and invest some or all of its net assets in investments of non-corporate issuers, including high quality, short-term debt securities. The Fund may not achieve its investment objectives when it does so.

Use of Leverage

The Fund currently utilizes leverage principally through its outstanding Preferred Shares and reverse repurchase agreements and may also obtain additional leverage through dollar rolls or borrowings, such as through bank loans or commercial paper and/or credit facilities. The Fund may also enter into transactions other than those noted above that may give rise to a form of leverage including, among others, futures and forward contracts (including foreign currency exchange contracts), total return swaps and other derivative transactions, loans of portfolio securities, short sales, when-issued, delayed delivery and forward commitment transactions and selling credit default swaps. The Fund may also determine to issue other types of preferred shares. Leveraging transactions pursued by the Fund may increase its duration and sensitivity to interest rate movements.

Depending upon market conditions and other factors, the Fund may or may not determine to add leverage following an offering to maintain or increase the total amount of leverage (as a percentage of the Fund’s total assets) that the Fund maintains, taking into account the additional assets raised through the issuance of Common Shares in such offering. The Fund utilizes certain kinds of leverage, such as reverse repurchase agreements and selling credit default swaps, opportunistically and may choose to increase or decrease, or eliminate entirely, its use of such leverage over time and from time to time based on PIMCO’s assessment of the yield curve environment, interest rate trends, market conditions and other factors. The Fund may also determine to decrease the leverage it currently maintains through its outstanding Preferred Shares through Preferred Shares redemptions or tender offers and may or may not determine to replace such leverage through other sources. If the Fund determines to add leverage following an offering, it is not possible to predict with accuracy the precise amount of leverage that would be added, in part because it is not possible to predict the number of Common Shares that ultimately will be sold in an offering or series of offerings. To the extent that the Fund does not add additional leverage following an offering, the Fund’s total amount of leverage as a percentage of its total assets will decrease, which could result in a reduction of investment income available for distribution to Common Shareholders.

The Fund also may borrow money for temporary purposes, to add leverage to the portfolio or for the settlement of securities transactions which otherwise might require untimely dispositions of portfolio securities held by the Fund.

PIMCO Income Strategy Fund (“PFL”)

The Fund’s investment objective is to seek high current income, consistent with the preservation of capital.

The Fund seeks to achieve its objective by ordinarily investing in a diversified portfolio of floating- and/or fixed-rate debt instruments. The Fund may invest a substantial portion of its floating-rate assets in floating-rate loans. Other floating-rate debt instruments in which the Fund may invest include catastrophe and other event-linked bonds, bank capital securities, unsecured and/or secured loans (including, but not limited to, bank and/or other syndicated loans and non-syndicated (private direct) loans), corporate bonds and other debt securities, money market instruments and certain types of mortgage-backed and other asset-backed securities that pay interest at rates that adjust whenever a specified interest rate changes and/or reset on predetermined dates (such as the last day of a month or calendar quarter). The Fund cannot assure you that it will achieve its investment objective, and you could lose all of your investment in the Fund.

Portfolio Management Strategies

Dynamic Allocation Strategy.  In managing the Fund, the Fund’s investment manager, PIMCO employs an active approach to allocation among multiple fixed income sectors based on, among other things, market conditions, valuation assessments, economic outlook, credit market trends and other economic factors. With PIMCO’s macroeconomic analysis as the basis for top-down investment decisions, including geographic and credit sector emphasis, PIMCO manages the Fund with a focus on seeking income generating investment ideas across multiple fixed income sectors, with an emphasis on seeking opportunities in developed and emerging global credit markets. The Fund has the flexibility to allocate assets in varying proportions among floating- and fixed-rate debt instruments, as well as among investment-grade and non-investment grade securities. It may focus more heavily or exclusively on an asset class at any time, based on assessments of relative values, market conditions and other factors. PIMCO may choose to focus on particular countries/regions, asset classes, industries and sectors to the exclusion of others at any time and from time to time based on market conditions and other factors. The relative value assessment within fixed income sectors draws on PIMCO’s regional and sector specialist insights. The Fund will observe various investment guidelines as summarized below.

Investment Selection Strategies.  Once the Fund’s top-down, portfolio positioning decisions have been made as described above, PIMCO selects particular investments for the Fund by employing a bottom-up, disciplined credit approach which is driven by fundamental, independent research within each sector/asset class represented in the Fund, with a focus on identifying securities and other instruments with solid and/or improving fundamentals.

ANNUAL REPORT | JUNE 30, 2023 147

The Funds’ Investment Objectives and Strategies (Cont.)

PIMCO utilizes strategies that focus on credit quality analysis, duration management and other risk management techniques. PIMCO attempts to identify, through fundamental research driven by independent credit analysis and proprietary analytical tools, debt obligations and other income-producing securities that provide current income and/or opportunities for capital appreciation based on its analysis of the issuer’s credit characteristics and the position of the security in the issuer’s capital structure.

Consideration of yield is only one component of the portfolio managers’ approach in managing the Fund. PIMCO also attempts to identify investments that may appreciate in value based on PIMCO’s assessment of the issuer’s credit characteristics, forecast for interest rates and outlook for particular countries/regions, currencies, industries, sectors and the global economy and bond markets generally.

Credit Quality.  The Fund may invest without limit in debt securities that are, at the time of purchase, rated below investment grade or that are unrated but judged by PIMCO to be of comparable quality (commonly referred to as “high yield” securities or “junk bonds”). The Fund will not normally invest more than 20% of its total assets in debt instruments, other than mortgage-related and other asset-backed securities, that are, at the time of purchase, rated CCC or lower by S&P and Fitch and Caa1 or lower by Moody’s, or that are unrated but determined by PIMCO to be of comparable quality. The Fund may invest without limit in mortgage-related and other asset-backed securities regardless of rating (i.e., of any credit quality). Subject to this 20% restriction, the Fund may invest in issuers of any credit quality (including bonds in the lowest ratings categories and securities that are in default or the issuers of which are in bankruptcy). For purposes of applying the foregoing policies, in the case of securities with split ratings (i.e., a security receiving two different ratings from two different rating agencies), the Fund will apply the higher of the applicable ratings. Subject to the aforementioned investment restrictions, the Fund may invest in securities of stressed issuers, which include securities at risk of being in default as to the repayment of principal and/or interest at the time of acquisition by the Fund or that are rated in the lower rating categories by one or more nationally recognized statistical rating organizations (for example, Ca or lower by Moody’s or CC or lower by S&P or Fitch) or, if unrated, are determined by PIMCO to be of comparable quality. Debt instruments of below investment grade quality are regarded as having predominantly speculative characteristics with respect to capacity to pay interest and to repay principal, and are commonly referred to as “high yield” securities or “junk bonds.” Debt instruments in the lowest investment grade category also may be considered to possess some speculative characteristics. The Fund may, for hedging, investment or leveraging purposes, make use of credit default swaps, which are contracts whereby one party makes periodic payments to a counterparty in

exchange for the right to receive from the counterparty a payment equal to the par (or other agreed-upon) value of a referenced debt obligation in the event of a default or other credit event by the issuer of the debt obligation.

Independent Credit Analysis.  PIMCO relies primarily on its own analysis of the credit quality and risks associated with individual debt instruments considered for the Fund, rather than relying exclusively on rating agencies or third-party research. The Fund’s portfolio managers utilize this information in an attempt to manage credit risk and/or to identify issuers, industries or sectors that are undervalued and/or offer attractive yields relative to PIMCO’s assessment of their credit characteristics. This aspect of PIMCO’s capabilities will be particularly important to the extent that the Fund invests in floating rate loans, high yield securities and in securities of emerging market issuers.

Duration Management.  It is expected that the Fund normally will have a short to intermediate average portfolio duration (i.e., within a zero to eight year (0 to 8) range), as calculated by PIMCO, although it may be shorter or longer at any time or from time to time depending on market conditions and other factors. While the Fund seeks to maintain a short to intermediate average portfolio duration, there is no limit on the maturity or duration of any individual security in which the Fund may invest. Duration is a measure used to determine the sensitivity of a security’s price to changes in interest rates. The Fund’s duration strategy may entail maintaining a negative average portfolio duration from time to time, which would potentially benefit the portfolio in an environment of rising market interest rates, but would generally adversely impact the portfolio in an environment of falling or neutral market interest rates. The Fund may use various derivatives strategies to manage (increase or decrease) the dollar-weighted average effective duration of the Fund’s portfolio. PIMCO may also utilize certain strategies, including without limit investments in structured notes or interest rate futures contracts or swap, cap, floor or collar transactions, for the purpose of reducing the interest rate sensitivity of the Fund’s portfolio, although there is no assurance that it will do so or that such strategies will be successful.

that adjust whenever a specified interest rate changes and/or reset on predetermined dates (such as the last day of a month or calendar quarter). The Fund also considers floating-rate assets to include securities with durations of less than or equal to one year and fixed-rate securities with respect to which the Fund has entered into derivative instruments to effectively convert the fixed-rate interest payments into floating-rate interest payments. The Fund also may invest in a wide variety of fixed-rate debt securities, including corporate bonds and mortgage-backed and other asset-backed securities issued on a public or private basis, including mortgage pass-through securities, collateralized mortgage obligations (“CMOs”), commercial or residential mortgage-backed securities, mortgage dollar rolls, CMO residuals, stripped mortgage-backed securities (“SMBSs”) and other securities that directly or indirectly represent a participation in, or are secured by and payable from, mortgage loans on real property. The Fund may make use of a variety of other instruments, including collateralized debt obligations, preferred securities, commercial paper, zero-coupon and inflation-indexed bonds, bank certificates of deposit, fixed time deposits and bankers’ acceptances, real estate investment trusts (“REITs”), bonds, debentures, notes, and other debt securities of U.S. and foreign (non-U.S.) corporate and other issuers; obligations of foreign governments or their sub-divisions, agencies and government sponsored enterprises and obligations of international agencies and supranational entities; municipal securities and other debt securities issued by states or local governments and their agencies, authorities and other government-sponsored enterprises, including taxable municipal securities (such as Build America Bonds); inflation-indexed bonds issued by both governments and corporations; structured notes, including hybrid or indexed securities; credit-linked notes; structured credit products; loans (including, among others, senior loans, delayed funding loans, revolving credit facilities and loan participations and assignments); covenant-lite obligations; preferred securities and convertible debt securities (i.e., debt securities that may be converted at either a stated price or stated rate into underlying shares of common stock), including synthetic convertible debt securities (i.e., instruments created through a combination of separate securities that possess the two principal characteristics of a traditional convertible security, such as an income-producing security and the right to acquire an equity security) and contingent convertible securities. Certain debt instruments, such as convertible bonds, also may include the right to participate in equity appreciation. The principal and/or interest rate on some debt instruments may be determined by reference to the performance of a benchmark asset or market, such as an index of securities, or the differential performance of two assets or markets, such as the level of exchange rates between the U.S. dollar and a foreign currency or currencies. The Fund may invest in debt securities of stressed, distressed and defaulted issuers. Subject to the Fund’s investment

limitations, at any given time and from time to time, substantially all of the Fund’s portfolio may consist of below investment grade securities. The Fund may invest in various levels of the capital structure of an issuer of mortgage-backed or asset-backed securities, including the equity or “first loss” tranche. For the avoidance of doubt, equity or “first loss” tranches of mortgage-backed or asset-backed securities do not constitute equity interests for purposes of the Fund’s 20% limit on investments in equity interests described below. The Fund may also invest, as a third party purchaser, in risk retention tranches of CMBS or other eligible securitizations, which are eligible residual interests held by the sponsors of such securitizations pursuant to the final rules implementing the credit risk retention requirements of Section 941 of the Dodd-Frank Act. The rate of interest on an income-producing security may be fixed, floating or variable.

The Fund invests predominantly in U.S. dollar-denominated debt securities, which may include those issued by foreign corporations or supra-national government agencies. Subject to the limitations set forth in the Fund’s prospectus, including the limit on investments in emerging market securities and instruments, the Fund may invest without limit in non-U.S. dollar denominated securities (of both developed and “emerging market” countries), including obligations of non-U.S. governments and their respective sub-divisions, agencies and government-sponsored enterprises. The Fund may invest up to 40% of its total assets in securities and instruments that are economically tied to “emerging market” countries other than investments in short-term investment grade sovereign debt issued by emerging market issuers, where as noted above there is no limit. The Fund may also invest directly in foreign currencies, including local emerging market currencies.

The Fund may invest up to 20% of its total assets in common stocks and other equity securities from time to time, including those it has received through the conversion of a convertible security held by the Fund or in connection with the restructuring of a debt security. Common stocks include common shares and other common equity interest issued by public or private issuers.

The Fund may, but is not required to, utilize various derivative strategies (both long and short positions) involving the purchase or sale of futures and forward contracts (including foreign currency exchange contracts), call and put options, credit default swaps, total return swaps, basis swaps and other swap agreements and other derivative instruments for investment purposes, leveraging purposes or in an attempt to hedge against market, credit, interest rate, currency and other risks in the portfolio. The Fund may purchase and sell securities on a when-issued, delayed delivery or forward commitment basis and may engage in short sales. The Fund may also seek to obtain market exposure to the securities in which it invests by entering into a series of purchase and sale contracts.

ANNUAL REPORT | JUNE 30, 2023 149

The Funds’ Investment Objectives and Strategies (Cont.)

The Fund has a policy not to concentrate investments in any particular industry, but may (consistent with that policy) invest up to 25% of its assets in any particular industry, and may invest a substantial portion of its assets in companies in related sectors, such as those in the banking or financial services sectors, which may share common characteristics and are often subject to similar business risks and regulatory burdens.

The Fund may invest in securities that have not been registered for public sale in the U.S. or relevant non-U.S. jurisdictions, including without limit securities eligible for purchase and sale pursuant to Rule 144A under the Securities Act of 1933, as amended, or relevant provisions of applicable non-U.S. law, and other securities issued in private placements. The Fund may invest in securities of other open- or closed-end investment companies (including those advised by PIMCO), including, without limitation, ETFs, to the extent that such investments are consistent with the Fund’s investment objectives, strategies and policies and permissible under the 1940 Act. The Fund may invest in other investment companies to gain broad market or sector exposure or for cash management purposes, including during periods when it has large amounts of uninvested cash or when PIMCO believes share prices of other investment companies offer attractive values. The Fund may invest in certain money market funds and/or short-term bond funds (“Central Funds”), to the extent permitted by the 1940 Act, the rules thereunder or exemptive relief therefrom. The Central Funds are registered investment companies created for use by certain registered investment companies advised by PIMCO in connection with their cash management activities. The Fund treats its investments in other investment companies that invest primarily in types of securities in which the Fund may invest directly as investments in such types of securities for purposes of the Fund’s investment policies (e.g., the Fund’s investment in an investment company that invests primarily in debt securities will be treated by the Fund as an investment in a debt security). As a shareholder in an investment company, the Fund would bear its ratable share of that investment company’s expenses and would remain subject to payment of the Fund’s management fees and other expenses with respect to assets so invested. Common Shareholders would therefore be subject to duplicative expenses to the extent the Fund invests in other investment companies. The securities of other investment companies may be leveraged, in which case the NAV and/or market value of the investment company’s shares will be more volatile than unleveraged investments. The Fund may invest in REITs. The Fund may invest in securities of companies of any market capitalization, including small and medium capitalizations.

The Fund may invest without limit in illiquid securities (i.e., securities that cannot be disposed of within seven days in the ordinary course of business at approximately the value at which the Fund has valued the securities).

The Fund may enter into repurchase agreements, in which the Fund purchases a security from a bank or broker-dealer and the bank or broker-dealer agrees to repurchase the security at the Fund’s cost plus interest within a specified time.

The Fund may lend its portfolio securities to brokers, dealers or other financial institutions provided a number of conditions are satisfied, including that the loan is fully collateralized.

The length of time the Fund has held a particular security is not generally a consideration in investment decisions. A change in the securities held by the Fund is known as “portfolio turnover.” The Fund may engage in frequent and active trading of portfolio securities to achieve its investment objective, particularly during periods of volatile market movements.

There have been no significant changes in the Fund’s portfolio turnover rates over the last two fiscal years, and no significant change to the portfolio turnover rates of the Fund described in the Financial Highlights can currently be predicted.

In connection with rating the Fund’s outstanding auction rate preferred shares of beneficial interest (“ARPS” and, together with any other preferred shares the Fund may have outstanding, “Preferred Shares”), Moody’s and Fitch impose asset coverage tests and other restrictions that may limit the Fund’s ability to engage in certain of the transactions described above.

Temporary defensive investments.  The Fund may make short-term investments when attempting to respond to adverse market, economic, political, or other conditions, as determined by PIMCO. Upon PIMCO’s recommendation, for temporary defensive purposes and in order to keep the Fund’s cash fully invested, the Fund may deviate from its investment strategy by investing some or all of its total assets in investments such as high grade debt securities, including high quality, short-term debt securities, and cash and cash equivalents. The Fund may not achieve its investment objective when it does so.

Use of Leverage

The Fund currently utilizes leverage principally through its outstanding Preferred Shares and reverse repurchase agreements and may also obtain additional leverage through dollar rolls or borrowings, such as through bank loans or commercial paper and/or other credit facilities.

The Fund may also enter into transactions other than those noted above that may give rise to a form of leverage including, among others, futures and forward contracts (including foreign currency exchange contracts), total return swaps and other derivative transactions, loans of portfolio securities, short sales, when-issued, delayed delivery and forward commitment transactions and selling

150 PIMCO CLOSED-END FUNDS

(Unaudited)

credit default swaps. The Fund may also determine to issue other types of preferred shares. Leveraging transactions pursued by the Fund may increase its duration and sensitivity to interest rate movements.

The Fund utilizes certain kinds of leverage, such as reverse repurchase agreements and selling credit default swaps, opportunistically and may choose to increase or decrease, or eliminate entirely, its use of such leverage over time and from time to time based on PIMCO’s assessment of the yield curve environment, interest rate trends, market conditions and other factors. The Fund may also determine to decrease the leverage it currently maintains through its outstanding Preferred Shares through Preferred Shares redemptions or tender offers and may or may not determine to replace such leverage through other sources.

The Fund also may borrow money in order to repurchase its shares or as a temporary measure for extraordinary or emergency purposes, including for the payment of dividends or the settlement of securities transactions which otherwise might require untimely dispositions of portfolio securities held by the Fund.

PIMCO Income Strategy Fund II (“PFN”)

The Fund’s investment objective is to seek high current income, consistent with the preservation of capital.

The Fund seeks to achieve its objective by ordinarily investing in a diversified portfolio of floating- and/or fixed-rate debt instruments. The Fund may invest a substantial portion of its floating-rate assets in floating-rate loans. Other floating-rate debt instruments in which the Fund may invest include catastrophe and other event-linked bonds, bank capital securities, unsecured and/or secured loans (including, but not limited to, bank and/or other syndicated loans and non-syndicated (private direct) loans), corporate bonds and other debt securities, money market instruments and certain types of mortgage-backed and other asset-backed securities that pay interest at rates that adjust whenever a specified interest rate changes and/or reset on predetermined dates (such as the last day of a month or calendar quarter). The Fund cannot assure you that it will achieve its investment objective, and you could lose all of your investment in the Fund.

Portfolio Management Strategies

Dynamic Allocation Strategy.  In managing the Fund, the Fund’s investment manager, PIMCO employs an active approach to allocation among multiple fixed income sectors based on, among other things, market conditions, valuation assessments, economic outlook, credit market trends and other economic factors. With PIMCO’s macroeconomic analysis as the basis for top-down investment decisions, including geographic and credit sector emphasis, PIMCO manages the Fund with a focus on seeking income generating investment ideas across multiple fixed income sectors, with an emphasis on seeking opportunities in developed and emerging global

credit markets. The Fund has the flexibility to allocate assets in varying proportions among floating- and fixed-rate debt instruments, as well as among investment-grade and non-investment grade securities. It may focus more heavily or exclusively on an asset class at any time, based on assessments of relative values, market conditions and other factors. PIMCO may choose to focus on particular countries/regions, asset classes, industries and sectors to the exclusion of others at any time and from time to time based on market conditions and other factors. The relative value assessment within fixed income sectors draws on PIMCO’s regional and sector specialist insights. The Fund will observe various investment guidelines as summarized below.

Investment Selection Strategies.  Once the Fund’s top-down, portfolio positioning decisions have been made as described above, PIMCO selects particular investments for the Fund by employing a bottom-up, disciplined credit approach which is driven by fundamental, independent research within each sector/asset class represented in the Fund, with a focus on identifying securities and other instruments with solid and/or improving fundamentals.

PIMCO utilizes strategies that focus on credit quality analysis, duration management and other risk management techniques. PIMCO attempts to identify, through fundamental research driven by independent credit analysis and proprietary analytical tools, debt obligations and other income-producing securities that provide current income and/or opportunities for capital appreciation based on its analysis of the issuer’s credit characteristics and the position of the security in the issuer’s capital structure.

Consideration of yield is only one component of the portfolio managers’ approach in managing the Fund. PIMCO also attempts to identify investments that may appreciate in value based on PIMCO’s assessment of the issuer’s credit characteristics, forecast for interest rates and outlook for particular countries/regions, currencies, industries, sectors and the global economy and bond markets generally.

Credit Quality.  The Fund may invest without limit in debt securities that are, at the time of purchase, rated below investment grade or that are unrated but judged by PIMCO to be of comparable quality (commonly referred to as “high yield” securities or “junk bonds”). The Fund will not normally invest more than 20% of its total assets in debt instruments, other than mortgage-related and other asset-backed securities, that are, at the time of purchase, rated CCC or lower by S&P and Fitch and Caa1 or lower by Moody’s, or that are unrated but determined by PIMCO to be of comparable quality. The Fund may invest without limit in mortgage-related and other asset-backed securities regardless of rating (i.e., of any credit quality). Subject to this 20% restriction, the Fund may invest in issuers of any credit quality (including bonds in the lowest ratings categories and securities

ANNUAL REPORT | JUNE 30, 2023 151

The Funds’ Investment Objectives and Strategies (Cont.)

that are in default or the issuers of which are in bankruptcy). For purposes of applying the foregoing policies, in the case of securities with split ratings (i.e., a security receiving two different ratings from two different rating agencies), the Fund will apply the higher of the applicable ratings. Subject to the aforementioned investment restrictions, the Fund may invest in securities of stressed issuers, which include securities at risk of being in default as to the repayment of principal and/or interest at the time of acquisition by the Fund or that are rated in the lower rating categories by one or more nationally recognized statistical rating organizations (for example, Ca or lower by Moody’s or CC or lower by S&P or Fitch) or, if unrated, are determined by PIMCO to be of comparable quality. Debt instruments of below investment grade quality are regarded as having predominantly speculative characteristics with respect to capacity to pay interest and to repay principal, and are commonly referred to as “high yield” securities or “junk bonds.” Debt instruments in the lowest investment grade category also may be considered to possess some speculative characteristics. The Fund may, for hedging, investment or leveraging purposes, make use of credit default swaps, which are contracts whereby one party makes periodic payments to a counterparty in exchange for the right to receive from the counterparty a payment equal to the par (or other agreed-upon) value of a referenced debt obligation in the event of a default or other credit event by the issuer of the debt obligation.

Independent Credit Analysis.  PIMCO relies primarily on its own analysis of the credit quality and risks associated with individual debt instruments considered for the Fund, rather than relying exclusively on rating agencies or third-party research. The Fund’s portfolio managers utilize this information in an attempt to manage credit risk and/or to identify issuers, industries or sectors that are undervalued and/or offer attractive yields relative to PIMCO’s assessment of their credit characteristics. This aspect of PIMCO’s capabilities will be particularly important to the extent that the Fund invests in floating rate loans, high yield securities and in securities of emerging market issuers.

Duration Management.  It is expected that the Fund normally will have a short to intermediate average portfolio duration (i.e., within a zero to eight year (0 to 8) range), as calculated by PIMCO, although it may be shorter or longer at any time or from time to time depending on market conditions and other factors. While the Fund seeks to maintain a short to intermediate average portfolio duration, there is no limit on the maturity or duration of any individual security in which the Fund may invest. Duration is a measure used to determine the sensitivity of a security’s price to changes in interest rates. The Fund’s duration strategy may entail maintaining a negative average portfolio duration from time to time, which would potentially benefit the portfolio in an environment of rising market interest rates, but would generally adversely impact the portfolio in an environment of falling or

neutral market interest rates. The Fund may use various derivatives strategies to manage (increase or decrease) the dollar-weighted average effective duration of the Fund’s portfolio. PIMCO may also utilize certain strategies, including without limit investments in structured notes or interest rate futures contracts or swap, cap, floor or collar transactions, for the purpose of reducing the interest rate sensitivity of the Fund’s portfolio, although there is no assurance that it will do so or that such strategies will be successful.

Portfolio Contents

The Fund seeks to achieve its investment objective by ordinarily investing in a diversified portfolio of floating- and/or fixed-rate debt instruments. The Fund may invest a substantial portion of its floating-rate assets in floating-rate loans. Other floating-rate debt instruments in which the Fund may invest include catastrophe and other event-linked bonds, bank capital securities, unsecured and/or secured loans (including, but not limited to, bank and/or other syndicated loans and non-syndicated (private direct) loans), corporate bonds and other debt securities, money market instruments and certain types of mortgage-backed and other asset-backed securities that pay interest at rates that adjust whenever a specified interest rate changes and/or reset on predetermined dates (such as the last day of a month or calendar quarter). The Fund also considers floating-rate assets to include securities with durations of less than or equal to one year and fixed-rate securities with respect to which the Fund has entered into derivative instruments to effectively convert the fixed-rate interest payments into floating-rate interest payments. The Fund also may invest in a wide variety of fixed-rate debt securities, including corporate bonds and mortgage-backed and other asset-backed securities issued on a public or private basis, including mortgage pass-through securities, collateralized mortgage obligations (“CMOs”), commercial or residential mortgage-backed securities, mortgage dollar rolls, CMO residuals, stripped mortgage-backed securities and other securities that directly or indirectly represent a participation in, or are secured by and payable from, mortgage loans on real property. The Fund may make use of a variety of other instruments, including collateralized debt obligations, preferred securities, commercial paper, zero-coupon and inflation-indexed bonds, bank certificates of deposit, fixed time deposits and bankers’ acceptances, real estate investment trusts (“REITs”), bonds, debentures, notes, and other debt securities of U.S. and foreign (non-U.S.) corporate and other issuers; obligations of foreign governments or their sub-divisions, agencies and government sponsored enterprises and obligations of international agencies and supranational entities; municipal securities and other debt securities issued by states or local governments and their agencies, authorities and other government-sponsored enterprises, including taxable municipal securities (such as Build America Bonds); inflation-indexed bonds issued by both governments and corporations;

(Unaudited)

structured notes, including hybrid or indexed securities; credit-linked notes; structured credit products; loans (including, among others, senior loans, delayed funding loans, revolving credit facilities and loan participations and assignments); covenant-lite obligations; preferred securities and convertible debt securities (i.e., debt securities that may be converted at either a stated price or stated rate into underlying shares of common stock), including synthetic convertible debt securities (i.e., instruments created through a combination of separate securities that possess the two principal characteristics of a traditional convertible security, such as an income-producing security and the right to acquire an equity security) and contingent convertible securities. Certain debt instruments, such as convertible bonds, also may include the right to participate in equity appreciation. The principal and/or interest rate on some debt instruments may be determined by reference to the performance of a benchmark asset or market, such as an index of securities, or the differential performance of two assets or markets, such as the level of exchange rates between the U.S. dollar and a foreign currency or currencies. The Fund may invest in debt securities of stressed, distressed and defaulted issuers.

Subject to the Fund’s investment limitations, at any given time and from time to time, substantially all of the Fund’s portfolio may consist of below investment grade securities. The Fund may invest in various levels of the capital structure of an issuer of mortgage-backed or asset-backed securities, including the equity or “first loss” tranche. For the avoidance of doubt, equity or “first loss” tranches of mortgage-backed or asset-backed securities do not constitute equity interests for purposes of the Fund’s 20% limit on investments in equity interests described below. The Fund may also invest, as a third party purchaser, in risk retention tranches of CMBS or other eligible securitizations, which are eligible residual interests held by the sponsors of such securitizations pursuant to the final rules implementing the credit risk retention requirements of Section 941 of the Dodd-Frank Act. The rate of interest on an income-producing security may be fixed, floating or variable.

The Fund invests predominantly in U.S. dollar-denominated debt securities, which may include those issued by foreign corporations or supra-national government agencies. Subject to the limitations set forth in the Fund’s prospectus, including the limit on investments in emerging market securities and instruments, the Fund may invest without limit in non-U.S. dollar denominated securities (of both developed and “emerging market” countries), including obligations of non-U.S. governments and their respective sub-divisions, agencies and government-sponsored enterprises. The Fund may invest up to 40% of its total assets in securities and instruments that are economically tied to “emerging market” countries other than investments in short-term investment grade sovereign debt issued by emerging market issuers, where as noted above there is no limit. The Fund may also invest directly in foreign currencies, including local emerging market currencies.

The Fund may invest up to 20% of its total assets in common stocks and other equity securities from time to time, including those it has received through the conversion of a convertible security held by the Fund or in connection with the restructuring of a debt security. Common stocks include common shares and other common equity interest issued by public or private issuers.

The Fund may, but is not required to, utilize various derivative strategies (both long and short positions) involving the purchase or sale of futures and forward contracts (including foreign currency exchange contracts), call and put options, credit default swaps, total return swaps, basis swaps and other swap agreements and other derivative instruments for investment purposes, leveraging purposes or in an attempt to hedge against market, credit, interest rate, currency and other risks in the portfolio. The Fund may purchase and sell securities on a when-issued, delayed delivery or forward commitment basis and may engage in short sales. The Fund may also seek to obtain market exposure to the securities in which it invests by entering into a series of purchase and sale contracts.

The Fund has a policy not to concentrate investments in any particular industry, but may (consistent with that policy) invest up to 25% of its assets in any particular industry, and may invest a substantial portion of its assets in companies in related sectors, such as those in the banking or financial services sectors, which may share common characteristics and are often subject to similar business risks and regulatory burdens. The Fund may invest in securities that have not been registered for public sale in the U.S. or relevant non-U.S. jurisdictions, including without limit securities eligible for purchase and sale pursuant to Rule 144A under the Securities Act of 1933, as amended, or relevant provisions of applicable non-U.S. law, and other securities issued in private placements. The Fund may invest in securities of other open- or closed-end investment companies (including those advised by PIMCO), including, without limitation, ETFs, to the extent that such investments are consistent with the Fund’s investment objectives, strategies and policies and permissible under the 1940 Act. The Fund may invest in other investment companies to gain broad market or sector exposure or for cash management purposes, including during periods when it has large amounts of uninvested cash or when PIMCO believes share prices of other investment companies offer attractive values. The Fund may invest in certain money market funds and/or short-term bond funds (“Central Funds”), to the extent permitted by the 1940 Act, the rules thereunder or exemptive relief therefrom. The Central Funds are registered investment companies created for use by certain registered investment companies advised by PIMCO in connection with their cash management activities. The Fund treats its investments in other investment companies that invest primarily in types of securities in which the Fund may invest directly as investments in such types of

ANNUAL REPORT | JUNE 30, 2023 153

The Funds’ Investment Objectives and Strategies (Cont.) (Unaudited)

securities for purposes of the Fund’s investment policies (e.g., the Fund’s investment in an investment company that invests primarily in debt securities will be treated by the Fund as an investment in a debt security). As a shareholder in an investment company, the Fund would bear its ratable share of that investment company’s expenses and would remain subject to payment of the Fund’s management fees and other expenses with respect to assets so invested. Common Shareholders would therefore be subject to duplicative expenses to the extent the Fund invests in other investment companies. The securities of other investment companies may be leveraged, in which case the NAV and/or market value of the investment company’s shares will be more volatile than unleveraged investments. The Fund may invest in REITs. The Fund may invest in securities of companies of any market capitalization, including small and medium capitalizations.

The Fund may invest without limit in illiquid securities (i.e., securities that cannot be disposed of within seven days in the ordinary course of business at approximately the value at which the Fund has valued the securities).

The Fund may enter into repurchase agreements, in which the Fund purchases a security from a bank or broker-dealer and the bank or broker-dealer agrees to repurchase the security at the Fund’s cost plus interest within a specified time.

The Fund may lend its portfolio securities to brokers, dealers or other financial institutions provided a number of conditions are satisfied, including that the loan is fully collateralized.

The length of time the Fund has held a particular security is not generally a consideration in investment decisions. A change in the securities held by the Fund is known as “portfolio turnover.” The Fund may engage in frequent and active trading of portfolio securities to achieve its investment objective, particularly during periods of volatile market movements.

There have been no significant changes in the Fund’s portfolio turnover rates over the last two fiscal years, and no significant change to the portfolio turnover rates of the Fund described in the Financial Highlights can currently be predicted.

In connection with rating the Fund’s outstanding auction rate preferred shares of beneficial interest (“ARPS” and, together with any other preferred shares the Fund may have outstanding, “Preferred Shares”), Moody’s and Fitch impose asset coverage tests and other restrictions that may limit the Fund’s ability to engage in certain of the transactions described above.

Temporary defensive investments.  The Fund may make short-term investments when attempting to respond to adverse market, economic, political, or other conditions, as determined by PIMCO. Upon PIMCO’s recommendation, for temporary defensive purposes

and in order to keep the Fund’s cash fully invested, the Fund may deviate from its investment strategy by investing some or all of its total assets in investments such as high grade debt securities, including high quality, short-term debt securities, and cash and cash equivalents. The Fund may not achieve its investment objective when it does so.

Use of Leverage

The Fund currently utilizes leverage principally through its outstanding Preferred Shares and reverse repurchase agreements and may also obtain additional leverage through dollar rolls or borrowings, such as through bank loans or commercial paper and/or other credit facilities.

The Fund may also enter into transactions other than those noted above that may give rise to a form of leverage including, among others, futures and forward contracts (including foreign currency exchange contracts), total return swaps and other derivative transactions, loans of portfolio securities, short sales, when-issued, delayed delivery and forward commitment transactions and selling credit default swaps. The Fund may also determine to issue other types of preferred shares. Leveraging transactions pursued by the Fund may increase its duration and sensitivity to interest rate movements.

The Fund utilizes certain kinds of leverage, such as reverse repurchase agreements and selling credit default swaps, opportunistically and may choose to increase or decrease, or eliminate entirely, its use of such leverage over time and from time to time based on PIMCO’s assessment of the yield curve environment, interest rate trends, market conditions and other factors. The Fund may also determine to decrease the leverage it currently maintains through its outstanding Preferred Shares through Preferred Shares redemptions or tender offers and may or may not determine to replace such leverage through other sources.

The Fund also may borrow money in order to repurchase its shares or as a temporary measure for extraordinary or emergency purposes, including for the payment of dividends or the settlement of securities transactions which otherwise might require untimely dispositions of portfolio securities held by the Fund.

154 PIMCO CLOSED-END FUNDS

Principal Risks of the Funds (Unaudited)

The factors that are most likely to have a material effect on a particular Fund’s portfolio as a whole are called “principal risks.” Each Fund is subject to the principal risks indicated below, as applicable, whether through direct investments, investments by a subsidiary (if applicable) or derivative positions. Each Fund may be subject to additional risks other than those described below because the types of investments made by a Fund can change over time.

Anti-Takeover Provisions

The Fund’s Amended and Restated Agreement and Declaration of Trust (the “Declaration of Trust”), as applicable, includes provisions that could limit the ability of other entities or persons to acquire control of the Fund or to convert the Fund to open-end status. These provisions in the Declaration of Trust could have the effect of depriving the holders (“Common Shareholders”) of the Fund’s common shares of beneficial interest (“Common Shares”) of opportunities to sell their Common Shares at a premium over the then-current market price of the Common Shares or at NAV.

Asset Allocation Risk

The Fund’s investment performance depends upon how its assets are allocated and reallocated. A principal risk of investing in the Fund is that PIMCO may make less than optimal or poor asset allocation decisions. PIMCO employs an active approach to allocation among multiple fixed-income sectors, but there is no guarantee that such allocation techniques will produce the desired results. It is possible that PIMCO will focus on an investment that performs poorly or underperforms other investments under various market conditions. You could lose money on your investment in the Fund as a result of these allocation decisions.

Call Risk

Call risk refers to the possibility that an issuer may exercise its right to redeem a fixed income security earlier than expected (a call). Issuers may call outstanding securities prior to their maturity for a number of reasons (e.g., declining interest rates, changes in credit spreads and improvements in the issuer’s credit quality). If an issuer calls a security in which the Fund has invested, the Fund may not recoup the full amount of its initial investment and may be forced to reinvest in lower-yielding securities, securities with greater credit risks or securities with other, less favorable features.

Certain Affiliations

Certain broker-dealers may be considered to be affiliated persons of the Fund and/or the Investment Manager due to their possible affiliations with Allianz SE, the ultimate parent of the Investment Manager, or another Allianz entity. Allianz Asset Management of America LP merged with Allianz Asset Management of America LLC (“Allianz Asset Management”), with the latter being the surviving entity, effective January 1, 2023. Following the merger, Allianz Asset

Management is PIMCO LLC’s managing member and direct parent entity. Absent an exemption from the SEC or other regulatory relief, the Fund is generally precluded from effecting certain principal transactions with affiliated brokers, and its ability to purchase securities being underwritten by an affiliated broker or a syndicate including an affiliated broker, or to utilize affiliated brokers for agency transactions, is subject to restrictions. This could limit the Fund’s ability to engage in securities transactions and take advantage of market opportunities.

The Fund has received exemptive relief from the SEC that, to the extent the Fund relies on such relief, permits it to (among other things) co-invest with certain other persons, including certain affiliates of the Investment Manager and certain public or private funds managed by the Investment Manager and its affiliates, subject to certain terms and conditions. The exemptive relief from the SEC with respect to co-investments imposes extensive conditions on any co-investments made in reliance on such relief.

Collateralized Bond Obligations, Collateralized Loan Obligations and Collateralized Debt Obligations Risk

CBOs, CLOs and CDOs may charge management fees and administrative expenses. For CBOs, CLOs and CDOs, the cash flows from the trust are split into two or more portions, called tranches, varying in risk and yield. The riskiest portion is the equity tranche which generally bears losses in connection with the first defaults, if any, on the bonds or loans in the trust. A senior tranche from a CLO, CBO and CDO trust typically has higher credit ratings and lower yields than the underlying securities. CLO, CBO and CDO tranches, even senior ones, can experience substantial losses due to actual defaults, increased sensitivity to defaults due to collateral default and disappearance of protecting tranches, market anticipation of defaults and aversion to CLO, CBO or other CDO securities. The risks of an investment in a CLO, CBO or other CDO depend largely on the type of the collateral securities and the class/tranche of the instrument in which the Fund invests. Normally, CLOs, CBOs and other CDOs are privately offered and sold, and thus are not registered under the securities laws. Investments in CLOs, CBOs and CDOs may be or become illiquid. In addition to the normal risks associated with debt instruments (e.g., interest rate risk and credit risk), CLOs, CBOs and CDOs carry additional risks including, but not limited to: (i) the possibility that distributions from the collateral will not be adequate to make interest or other payments; (ii) the risk that the quality of the collateral may decline in value or default; (iii) the risk that the Fund may invest in CBOs, CLOs or other CDOs that are subordinate to other classes; and (iv) the risk that the complex structure of the security may not be fully understood at the time of investment and may produce disputes with the issuer or others and may produce unexpected investment results.

ANNUAL REPORT | JUNE 30, 2023 155

Principal Risks of the Funds (Cont.)

Confidential Information Access Risk

In managing the Fund (and other PIMCO clients), PIMCO may from time to time have the opportunity to receive material, non-public information (“Confidential Information”) about the issuers of certain investments, including, without limitation, senior floating rate loans, other loans and related investments being considered for acquisition by the Fund or held in the Fund’s portfolio. For example, an issuer of privately placed loans considered by the Fund may offer to provide PIMCO with financial information and related documentation regarding the issuer that is not publicly available. Pursuant to applicable policies and procedures, PIMCO may (but is not required to) seek to avoid receipt of Confidential Information from the issuer so as to avoid possible restrictions on its ability to purchase and sell investments on behalf of the Fund and other clients to which such Confidential Information relates. In such circumstances, the Fund (and other PIMCO clients) may be disadvantaged in comparison to other investors, including with respect to the price the Fund pays or receives when it buys or sells an investment. Further, PIMCO’s and the Fund’s abilities to assess the desirability of proposed consents, waivers or amendments with respect to certain investments may be compromised if they are not privy to available Confidential Information. PIMCO may also determine to receive such Confidential Information in certain circumstances under its applicable policies and procedures. If PIMCO intentionally or unintentionally comes into possession of Confidential Information, it may be unable, potentially for a substantial period of time, to purchase or sell investments to which such Confidential Information relates.

Contingent Convertible Securities Risk

Contingent convertible securities (“CoCos”) have no stated maturity, have fully discretionary coupons and are typically issued in the form of subordinated debt instruments. CoCos generally either convert into equity or have their principal written down (including potentially to zero) upon the occurrence of certain triggering events (“triggers”) linked to regulatory capital thresholds or regulatory actions relating to the issuer’s continued viability. As a result, an investment by the Fund in CoCos is subject to the risk that coupon (i.e., interest) payments may be cancelled by the issuer or a regulatory authority in order to help the issuer absorb losses and the risk of total loss. An investment by the Fund in CoCos is also subject to the risk that, in the event of the liquidation, dissolution or winding-up of an issuer prior to a trigger event, the Fund’s rights and claims will generally rank junior to the claims of holders of the issuer’s other debt obligations and CoCos may also be treated as junior to an issuer’s other obligations and securities. In addition, if CoCos held by the Fund are converted into the issuer’s underlying equity securities following a trigger event, the Fund’s holding may be further subordinated due to the conversion from a debt to equity instrument. Further, the value of an investment in CoCos is unpredictable and will be

influenced by many factors and risks, including interest rate risk, credit risk, market risk and liquidity risk. An investment by the Fund in CoCos may result in losses to the Fund.

Convertible Securities Risk

The market values of convertible securities may decline as interest rates increase and, conversely, may increase as interest rates decline. A convertible security’s market value, however, tends to reflect the market price of the common stock of the issuing company when that stock price approaches or is greater than the convertible security’s “conversion price.” The conversion price is defined as the predetermined price at which the convertible security could be exchanged for the associated stock. As the market price of the underlying common stock declines, the price of the convertible security tends to be influenced more by the yield of the convertible security. Thus, it may not decline in price to the same extent as the underlying common stock. In the event of a liquidation of the issuing company, holders of convertible securities may be paid before the company’s common stockholders but after holders of any senior debt obligations of the company. Consequently, the issuer’s convertible securities generally entail less risk than its common stock but more risk than its other debt obligations. Convertible securities are often rated below investment grade or not rated.

Counterparty Risk

The Fund will be subject to credit risk with respect to the counterparties to the derivative contracts and other instruments entered into by the Fund or held by special purpose or structured vehicles in which the Fund invests. In the event that the Fund enters into a derivative transaction with a counterparty that subsequently becomes insolvent or becomes the subject of a bankruptcy case, the derivative transaction may be terminated in accordance with its terms and the Fund’s ability to realize its rights under the derivative instrument and its ability to distribute the proceeds could be adversely affected. If a counterparty becomes bankrupt or otherwise fails to perform its obligations under a derivative contract due to financial difficulties, the Fund may experience significant delays in obtaining any recovery (including recovery of any collateral it has provided to the counterparty) in a dissolution, assignment for the benefit of creditors, liquidation, winding-up, bankruptcy or other analogous proceeding. In addition, in the event of the insolvency of a counterparty to a derivative transaction, the derivative transaction would typically be terminated at its fair market value. If the Fund is owed this fair market value in the termination of the derivative transaction and its claim is unsecured, the Fund will be treated as a general creditor of such counterparty and will not have any claim with respect to any underlying security or asset. The Fund may obtain only a limited recovery or may obtain no recovery in such circumstances. While the

156 PIMCO CLOSED-END FUNDS

(Unaudited)

Fund may seek to manage its counterparty risk by transacting with a number of counterparties, concerns about the solvency of, or a default by, one large market participant could lead to significant impairment of liquidity and other adverse consequences for other counterparties.

“Covenant-Lite” Obligations Risk

Covenant-lite obligations contain fewer maintenance covenants than other obligations, or no maintenance covenants, and may not include terms that allow the lender to monitor the performance of the borrower and declare a default if certain criteria are breached. Covenant-lite loans may carry more risk than traditional loans as they allow individuals and corporations to engage in activities that would otherwise be difficult or impossible under a covenant-heavy loan agreement. In the event of default, covenant-lite loans may exhibit diminished recovery values as the lender may not have the opportunity to negotiate with the borrower prior to default.

Credit Default Swaps Risk

Credit default swap agreements may involve greater risks than if the Fund had invested in the reference obligation directly since, in addition to general market risks, credit default swaps are subject to leverage risk, illiquidity risk, counterparty risk and credit risk. A buyer generally also will lose its investment and recover nothing should no credit event occur and the swap is held to its termination date. If a credit event were to occur, the value of any deliverable obligation received by the seller (if any), coupled with the upfront or periodic payments previously received, may be less than the full notional value it pays to the buyer, resulting in a loss of value to the seller. When the Fund acts as a seller of a credit default swap, it is exposed to many of the same risks of leverage described herein. As the seller, the Fund would receive a stream of payments over the term of the swap agreement provided that no event of default has occurred with respect to the referenced debt obligation upon which the swap is based. The Fund would effectively add leverage to its portfolio because, if a default occurs, the stream of payments may stop and, in addition to its total net assets, the Fund would be subject to investment exposure on the notional amount of the swap.

Although the Fund may seek to realize gains by selling credit default swaps that increase in value, to realize gains on selling credit default swaps, an active secondary market for such instruments must exist or the Fund must otherwise be able to close out these transactions at advantageous times. In addition to the risk of losses described above, if no such secondary market exists or the Fund is otherwise unable to close out these transactions at advantageous times, selling credit default swaps may not be profitable for the Fund.

The market for credit default swaps has become more volatile as the creditworthiness of certain counterparties has been questioned and/or

downgraded. The Fund will be subject to credit risk with respect to the counterparties to the credit default swap contract (whether a clearing corporation or another third party). If a counterparty’s credit becomes significantly impaired, multiple requests for collateral posting in a short period of time could increase the risk that the Fund may not receive adequate collateral. The Fund may exit its obligations under a credit default swap only by terminating the contract and paying applicable breakage fees, or by entering into an offsetting credit default swap position, which may cause the Fund to incur more losses.

Credit Risk

The Fund could lose money if the issuer or guarantor of a fixed income security (including a security purchased with securities lending collateral), or the counterparty to a derivatives contract, repurchase agreement or a loan of portfolio securities is unable or unwilling, or is perceived (whether by market participants, rating agencies, pricing services or otherwise) as unable or unwilling, to make timely principal and/or interest payments or to otherwise honor its obligations. The risk that such issuer, guarantor or counterparty is less willing or able to do so is heightened in market environments where interest rates are rising. The downgrade of the credit of a security held by the Fund may decrease its value. Measures such as average credit quality may not accurately reflect the true credit risk of the Fund. This is especially the case if the Fund consists of securities with widely varying credit ratings. Securities are subject to varying degrees of credit risk, which are often reflected in credit ratings. Credit risk is greater to the extent the Fund uses leverage or derivatives. Rising or high interest rates may deteriorate the credit quality of an issuer or counterparty, particularly if an issuer or counterparty faces challenges rolling or refinancing its obligations.

CSDR Related Risk

The European Union has adopted a settlement discipline regime under Regulation (EU) No 909/2014 and the Settlement Discipline RTS as they may be modified from time to time (“CSDR”), which will have phased compliance dates. It aims to reduce the number of settlement fails that occur in EEA central securities depositories (“CSDs”) and address settlement fails where they occur. The key elements of the regime are: (i) mandatory buy-ins — if a settlement fail continues for a specified period of time after the intended settlement date, a buy-in process must be initiated to effect the settlement; (ii) cash penalties — EEA CSDs are required to impose cash penalties on participants that cause settlement fails and distribute these to receiving participants; and (iii) allocations and confirmations — EEA investment firms are required to take measures to prevent settlement fails, including putting in place arrangements with their professional clients to communicate securities allocations and transaction confirmations. These requirements apply to transactions in transferable securities (e.g., shares and bonds), money market instruments, units in funds

ANNUAL REPORT | JUNE 30, 2023 157

Principal Risks of the Funds (Cont.)

and emission allowances that are to be settled via an EEA CSD and, in the case of cash penalties and buy-in requirements only, are admitted to trading or traded on an EEA trading venue or cleared by an EEA central counterparty. If the Fund enters into in-scope transactions, the CSDR settlement discipline regime may result in increased operational and compliance costs being borne directly or indirectly by the Fund. CSDR may also affect liquidity and increase trading costs associated with relevant securities. If in-scope transactions are subject to additional expenses and penalties as a consequence of the CSDR settlement discipline regime, such expenses and penalties may be charged to the relevant Fund.

Currency Risk

If the Fund invests directly in foreign (non-U.S.) currencies or in securities that trade in, and receive revenues in, foreign (non-U.S.) currencies, or in derivatives or other instruments that provide exposure to foreign (non-U.S.) currencies, it will be subject to the risk that those currencies will decline in value relative to the U.S. dollar, or, in the case of hedging positions, that the U.S. dollar will decline in value relative to the currency being hedged. Although the Fund may attempt to hedge its currency exposure into the U.S. dollar, it may not be successful in reducing the effects of currency fluctuations. The Fund may also hedge from one foreign currency to another. In addition, the Fund’s use of currency hedging may not be successful and the use of such strategies may lower the Fund’s potential returns.

Investments denominated in foreign (non-U.S.) currencies or that trade in and receive revenues in, foreign (non-U.S.) currencies, derivatives or other instruments that provide exposure to foreign (non-U.S.) currencies, are subject to the risk that those currencies will decline in value relative to the U.S. dollar, or, in the case of hedging positions, that the U.S. dollar will decline in value relative to the currency being hedged.

Currency rates in foreign (non-U.S.) countries may fluctuate significantly over short periods of time for a number of reasons, including changes in interest rates, rates of inflation, balance of payments and governmental surpluses or deficits, intervention (or the failure to intervene) by U.S. or foreign (non-U.S.) governments, central banks or supranational entities such as the International Monetary Fund, or by the imposition of currency controls or other political developments in the United States or abroad. These fluctuations may have a significant adverse impact on the value of the Fund’s portfolio and/or the level of Fund distributions made to Common Shareholders. There is no assurance that a hedging strategy, if used, will be successful.

Moreover, currency hedging techniques may be unavailable with respect to emerging market currencies. As a result, the Fund’s investments in foreign currency-denominated, and especially emerging market-currency denominated, securities may reduce the returns of the Fund.

Cyber Security Risk

As the use of technology has become more prevalent in the course of business, the Fund is potentially more susceptible to operational and information security risks resulting from breaches in cyber security. A breach in cyber security refers to both intentional and unintentional cyber events from outside threat actors or internal resources that may, among other things, cause the Fund to lose proprietary information, suffer data corruption and/or destruction, lose operational capacity, result in the unauthorized release or other misuse of confidential information, or otherwise disrupt normal business operations. Cyber security breaches may involve unauthorized access to the Fund’s digital information systems (e.g., through “hacking” or malicious software coding), and may come from multiple sources, including outside attacks such as denial-of-service attacks (i.e., efforts to make network services unavailable to intended users) or cyber extortion, including exfiltration of data held for ransom and/or “ransomware” attacks that renders systems inoperable until ransom is paid, or insider actions. In addition, cyber security breaches involving the Fund’s third party service providers (including but not limited to advisers, sub-advisers, administrators, transfer agents, custodians, vendors, suppliers, distributors and other third parties), trading counterparties or issuers in which the Fund invests can also subject the Fund to many of the same risks associated with direct cyber security breaches or extortion of company data. Moreover, cyber security breaches involving trading counterparties or issuers in which the Fund invests could adversely impact such counterparties or issuers and cause the Fund’s investments to lose value. In addition, work-from-home arrangements by the Fund, the Investment Manager or their service providers could increase all of the above risks, create additional data and information accessibility concerns, and make the Fund, the Investment Manager or their service providers susceptible to operational disruptions, any of which could adversely impact their operations.

Cyber security failures or breaches may result in financial losses to the Fund and its shareholders. These failures or breaches may also result in disruptions to business operations, potentially resulting in financial losses; interference with the Fund’s ability to calculate its NAV, process shareholder transactions or otherwise transact business with shareholders; impediments to trading; violations of applicable privacy and other laws; regulatory fines; penalties; third party claims in litigation; reputational damage; reimbursement or other compensation costs; additional compliance and cyber security risk management costs and other adverse consequences. In addition, substantial costs may be incurred in order to prevent any cyber incidents in the future.

Like with operational risk in general, the Fund has established business continuity plans and risk management systems designed to reduce the risks associated with cyber security. However, there are

158 PIMCO CLOSED-END FUNDS

(Unaudited)

inherent limitations in these plans and systems, including that certain risks may not have been identified, in large part because different or unknown threats may emerge in the future. As such, there is no guarantee that such efforts will succeed, especially because the Fund does not directly control the cyber security systems of issuers in which the Fund may invest, trading counterparties or third party service providers to the Fund. Such entities have experienced cyber attacks and other attempts to gain unauthorized access to systems from time to time, and there is no guarantee that efforts to prevent or mitigate the effects of such attacks or other attempts to gain unauthorized access will be successful. There is also a risk that cyber security breaches may not be detected. The Fund and its shareholders may suffer losses as a result of a cyber security breach related to the Fund, its service providers, trading counterparties or the issuers in which the Fund invests.

Debt Securities Risk

Debt securities are generally subject to the risks described below and further herein:

Issuer risk.  The value of debt securities may decline for a number of reasons that directly relate to the issuer, such as management performance, financial leverage, reduced demand for the issuer’s goods and services, historical and prospective earnings of the issuer and the value of the assets of the issuer.

Interest rate risk.  The market value of debt securities changes in response to interest rate changes and other factors. Interest rate risk is the risk that prices of debt securities will increase as interest rates fall and decrease as interest rates rise, which would be reflected in the Fund’s NAV. The Fund may lose money if short-term or long-term interest rates rise sharply in a manner not anticipated by the Fund’s management. Moreover, because rates on certain floating rate debt securities typically reset only periodically, changes in prevailing interest rates (and particularly sudden and significant changes) can be expected to cause some fluctuations in the NAV of the Fund to the extent that it invests in floating rate debt securities.

Prepayment risk.  During periods of declining interest rates, borrowers may prepay principal. This may force the Fund to reinvest in lower yielding securities, resulting in a possible decline in the Fund’s income and distributions.

Credit risk.  Credit risk is the risk that one or more debt securities in the Fund’s portfolio will decline in price or fail to pay interest or principal when due because the issuer of the security experiences a decline in its financial status. Credit risk is increased when a portfolio security is downgraded or the perceived creditworthiness of the issuer deteriorates.

Reinvestment risk.  Reinvestment risk is the risk that income from the Fund’s portfolio will decline if the Fund invests the proceeds from matured, traded or called fixed income securities at market interest rates that are below the portfolio’s current earnings rate.

Duration and maturity risk.  The Fund may seek to adjust the duration or maturity of its investments in debt securities based on its assessment of current and projected market conditions. The Fund may incur costs in seeking to adjust the average duration or maturity of its portfolio of debt securities. There can be no assurances that the Fund’s assessment of current and projected market conditions will be correct or that any strategy to adjust duration or maturity will be successful.

In addition, from time to time, uncertainty regarding the status of negotiations in the U.S. government to increase the statutory debt ceiling could impact the creditworthiness of the United States and could impact the liquidity and value of U.S. Government and other securities and ultimately the Fund.

Derivatives Risk

The Fund may, but is not required to, utilize a variety of derivative instruments (both long and short positions) for investment or risk management purposes. Derivatives are financial contracts whose value depends on, or is derived from, the value of an underlying asset, reference rate or index. For example, the Fund may use derivative instruments for purposes of increasing liquidity, providing efficient portfolio management, broadening investment opportunities (including taking short or negative positions), implementing a tax or cash management strategy, gaining exposure to a particular security or segment of the market, modifying the effective duration of the Fund’s portfolio investments and/or enhancing total return.

The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. Derivatives and other similar instruments (referred to collectively as “derivatives”), which may increase market exposure are subject to a number of risks including leverage risk, liquidity risk (which may be heightened for highly customized derivatives), interest rate risk, market risk, counterparty (including credit) risk, operational risk (such as documentation issues, settlement issues and systems failures), legal risk (such as insufficient documentation, insufficient capacity or authority of a counterparty, and issues with the legality or enforceability of a contract), counterparty risk, tax risk and management risk, as well as risks arising from changes in applicable requirements, risks arising from margin requirements and risks arising from mispricing or valuation complexity. They also involve the risk that changes in the value of a derivative instrument may not correlate perfectly with the underlying asset, rate or index. By investing in a

ANNUAL REPORT | JUNE 30, 2023 159

Principal Risks of the Funds (Cont.)

derivative instrument, the Fund could lose more than the initial amount invested, and derivatives may increase the volatility of the Fund, especially in unusual or extreme market conditions. Certain derivatives have the potential for unlimited loss, regardless of the size of the initial investment. The 1940 Act and related rules no longer require asset segregation for derivatives transactions, however asset segregation and posting of collateral may still be utilized for risk management or other purposes. The Fund may be required to hold additional cash or sell other investments in order to obtain cash to close out a position and changes in the value of a derivative may also create margin delivery or settlement payment obligations for the Fund. Also, suitable derivative transactions may not be available in all circumstances and there can be no assurance that the Fund will engage in these transactions to reduce exposure to other risks when that would be beneficial or that, if used, such strategies will be successful. The Fund’s use of derivatives may increase or accelerate the amount of taxes payable by Common Shareholders.

Over-the-counter (“OTC”) derivatives are also subject to the risk that a counterparty to the transaction will not fulfill its contractual obligations to the other party, as many of the protections afforded to centrally cleared derivative transactions might not be available for OTC derivatives. The primary credit risk on derivatives that are exchange-traded or traded through a central clearing counterparty resides with the Fund’s clearing broker, or the clearinghouse itself.

Participation in the markets for derivative instruments involves investment risks and transaction costs to which the Fund may not be subject absent the use of these strategies. The skills needed to successfully execute derivative strategies may be different from those needed for other types of transactions. If the Fund incorrectly forecasts the value and/or creditworthiness of securities, currencies, interest rates, counterparties or other economic factors involved in a derivative transaction, the Fund might have been in a better position if the Fund had not entered into such derivative transaction. In evaluating the risks and contractual obligations associated with particular derivative instruments, it is important to consider that certain derivative transactions may be modified or terminated only by mutual consent of the Fund and its counterparty.

Therefore, it may not be possible for the Fund to modify, terminate, or offset the Fund’s obligations or the Fund’s exposure to the risks associated with a derivative transaction prior to its scheduled termination or maturity date, which may create a possibility of increased volatility and/or decreased liquidity to the Fund. Hedges are sometimes subject to imperfect matching between the derivative and the underlying instrument, and there can be no assurance that the Fund’s hedging transactions will be effective. In such case, the Fund may lose money.

Because the markets for certain derivative instruments (including markets located in foreign countries) are relatively new and still developing, appropriate derivative transactions may not be available in all circumstances for risk management or other purposes. Upon the expiration of a particular contract, the Fund may wish to retain the Fund’s position in the derivative instrument by entering into a similar contract but may be unable to do so if the counterparty to the original contract is unwilling to enter into the new contract and no other appropriate counterparty can be found. When such markets are unavailable, the Fund will be subject to increased liquidity and investment risk.

The Fund may enter into opposite sides of interest rate swap and other derivatives for the principal purpose of generating distributable gains on the one side (characterized as ordinary income for tax purposes) that are not part of the Fund’s duration or yield curve management strategies (“paired swap transactions”), and with a substantial possibility that the Fund will experience a corresponding capital loss and decline in NAV with respect to the opposite side transaction (to the extent it does not have corresponding offsetting capital gains). Consequently, Common Shareholders may receive distributions and owe tax on amounts that are effectively a taxable return of the shareholder’s investment in the Fund, at a time when their investment in the Fund has declined in value, which tax may be at ordinary income rates. The tax treatment of certain derivatives in which the Fund invests may be unclear and thus subject to recharacterization. Any recharacterization of payments made or received by the Fund pursuant to derivatives potentially could affect the amount, timing or character of Fund distributions. In addition, the tax treatment of such investment strategies may be changed by regulation or otherwise.

When a derivative is used as a hedge against a position that the Fund holds, any loss generated by the derivative generally should be substantially offset by gains on the hedged investment, and vice versa. Although hedging can reduce or eliminate losses, it can also reduce or eliminate gains. Hedges are sometimes subject to imperfect matching between the derivative and the underlying instrument, and there can be no assurance that the Fund’s hedging transactions will be effective. The regulation of the derivatives markets has increased over the past several years, and additional future regulation of the derivatives markets may make derivatives more costly, may limit the availability or reduce the liquidity of derivatives, or may otherwise adversely affect the value or performance of derivatives. Any such adverse future developments could impair the effectiveness or raise the costs of the Fund’s derivative transactions, impede the employment of the Fund’s derivatives strategies, or adversely affect the Fund’s performance.

160 PIMCO CLOSED-END FUNDS

Distressed and Defaulted Securities Risk

Investments in the securities of financially distressed issuers involve substantial risks, including the risk of default. Distressed securities generally trade significantly below “par” or full value because investments in such securities and debt of distressed issuers or issuers in default are considered speculative and involve substantial risks in addition to the risks of investing in high-yield bonds. Such investments may be in default at the time of investment. In addition, these securities may fluctuate more in price, and are typically less liquid. The Fund also will be subject to significant uncertainty as to when, and in what manner, and for what value obligations evidenced by securities of financially distressed issuers will eventually be satisfied. Defaulted obligations might be repaid only after lengthy workout or bankruptcy proceedings, during which the issuer might not make any interest or other payments. In any such proceeding relating to a defaulted obligation, the Fund may lose its entire investment or may be required to accept cash or securities with a value substantially less than its original investment. Moreover, any securities received by the Fund upon completion of a workout or bankruptcy proceeding may be less liquid, speculative or restricted as to resale. Similarly, if the Fund participates in negotiations with respect to any exchange offer or plan of reorganization with respect to the securities of a distressed issuer, the Fund may be restricted from disposing of such securities. To the extent that the Fund becomes involved in such proceedings, the Fund may have a more active participation in the affairs of the issuer than that assumed generally by an investor. The Fund may incur additional expenses to the extent it is required to seek recovery upon a default in the payment of principal or interest on its portfolio holdings.

Also among the risks inherent in investments in a troubled issuer is that it frequently may be difficult to obtain information as to the true financial condition of such issuer. PIMCO’s judgments about the credit quality of a financially distressed issuer and the relative value of its securities may prove to be wrong.

Distribution Rate Risk

Although the Fund may seek to maintain level distributions, the Fund’s distribution rates may be affected by numerous factors, including but not limited to changes in realized and projected market returns, fluctuations in market interest rates, Fund performance, and other factors. There can be no assurance that a change in market conditions or other factors will not result in a change in the Fund’s distribution rate or that the rate will be sustainable in the future.

For instance, during periods of low or declining interest rates, the Fund’s distributable income and dividend levels may decline for many reasons. For example, the Fund may have to deploy uninvested assets (whether from sales of Fund shares, proceeds from matured, traded or called debt obligations or other sources) in new, lower yielding

instruments. Additionally, payments from certain instruments that may be held by the Fund (such as variable and floating rate securities) may be negatively impacted by declining interest rates, which may also lead to a decline in the Fund’s distributable income and dividend levels.

Emerging Markets Risk

Foreign (non U.S.) investment risk may be particularly high to the extent that the Fund invests in securities of issuers based in or doing business in emerging market countries or invests in securities denominated in the currencies of emerging market countries. Investing in securities of issuers based in or doing business in emerging markets entails all of the risks of investing in foreign securities noted above, but to a heightened degree.

Investments in emerging market countries pose a greater degree of systemic risk (i.e., the risk of a cascading collapse of multiple institutions within a country, and even multiple national economies). The inter-relatedness of economic and financial institutions within and among emerging market economies has deepened over the years, with the effect that institutional failures and/or economic difficulties that are of initially limited scope may spread throughout a country, a region or all or most emerging market countries. This may undermine any attempt by the Fund to reduce risk through geographic diversification of its portfolio.

There is a heightened possibility of imposition of withholding taxes on interest or dividend income generated from emerging market securities. Governments of emerging market countries may engage in confiscatory taxation or expropriation of income and/or assets to raise revenues or to pursue a domestic political agenda. In the past, emerging market countries have nationalized assets, companies and even entire sectors, including the assets of foreign investors, with inadequate or no compensation to the prior owners. There can be no assurance that the Fund will not suffer a loss of any or all of its investments, or interest or dividends thereon, due to adverse fiscal or other policy changes in emerging market countries.

There is also a greater risk that an emerging market government may take action that impedes or prevents the Fund from taking income and/or capital gains earned in the local currency and converting into U.S. dollars (i.e., “repatriating” local currency investments or profits). Certain emerging market countries have sought to maintain foreign exchange reserves and/or address the economic volatility and dislocations caused by the large international capital flows by controlling or restricting the conversion of the local currency into other currencies. This risk tends to become more acute when economic conditions otherwise worsen. There can be no assurance that if the Fund earns income or capital gains in an emerging market currency or PIMCO otherwise seeks to withdraw the Fund’s investments from a

ANNUAL REPORT | JUNE 30, 2023 161

Principal Risks of the Funds (Cont.)

given emerging market country, capital controls imposed by such country will not prevent, or cause significant expense, or delay in, doing so.

Bankruptcy law and creditor reorganization processes may differ substantially from those in the United States, resulting in greater uncertainty as to the rights of creditors, the enforceability of such rights, reorganization timing and the classification, seniority and treatment of claims. In certain emerging market countries, although bankruptcy laws have been enacted, the process for reorganization remains highly uncertain. In addition, it may be impossible to seek legal redress against an issuer that is a sovereign state.

Emerging market countries typically have less established legal, accounting, recordkeeping and financial reporting systems than those in more developed markets, which may reduce the scope or quality of financial information available to investors. Governments in emerging market countries are often less stable and more likely to take extra-legal action with respect to companies, industries, assets, or foreign ownership than those in more developed markets. Moreover, it can be more difficult for investors to bring litigation or enforce judgments against issuers in emerging markets or for U.S. regulators to bring enforcement actions against such issuers. The Fund may also be subject to emerging markets risk if it invests in derivatives or other securities or instruments whose value or return are related to the value or returns of emerging markets securities.

Other heightened risks associated with emerging markets investments include without limitation (i) risks due to less social, political and economic stability; (ii) the smaller size of the market for such securities and a lower volume of trading, resulting in a lack of liquidity and in price volatility; (iii) certain national policies which may restrict the Fund’s investment opportunities, including sanctions and restrictions on investing in issuers or industries deemed sensitive to relevant national interests and requirements that government approval be obtained prior to investment by foreign persons; (iv) certain national policies that may restrict the Fund’s repatriation of investment income, capital or the proceeds of sales of securities, including temporary restrictions on foreign capital remittances; (v) the lack of uniform accounting and auditing standards and/or standards that may be significantly different from the standards required in the United States; (vi) less publicly available financial and other information regarding issuers; (vii) potential difficulties in enforcing contractual obligations; and (viii) higher rates of inflation, higher interest rates and other economic concerns. The Fund may invest to a substantial extent in emerging market securities that are denominated in local currencies, subjecting the Fund to a greater degree of foreign currency risk. Also, investing in emerging market countries may entail purchases of securities of issuers that are insolvent, bankrupt or otherwise of

questionable ability to satisfy their payment obligations as they become due, subjecting the Fund to a greater amount of credit risk and/or high yield risk. The economy of some emerging markets may be particularly exposed to or affected by a certain industry or sector, and therefore issuers and/or securities of such emerging markets may be more affected by the performance of such industries or sectors.

Equity Securities and Related Market Risk

The market price of common stocks and other equity securities may go up or down, sometimes rapidly or unpredictably. Equity securities may decline in value due to factors affecting equity securities markets generally, particular industries represented in those markets, or the issuer itself. The values of equity securities may decline due to real or perceived adverse economic conditions, changes in the general outlook for corporate earnings, changes in interest or currency rates, adverse changes to credit markets or adverse investor sentiment generally. They may also decline due to labor shortages or increased production costs and competitive conditions within an industry. Equity securities generally have greater price volatility than bonds and other debt securities.

Different types of equity securities provide different voting and dividend rights and priority in the event of the bankruptcy and/or insolvency of the issuer. In addition to common stock, equity securities may include preferred securities, convertible securities and warrants. Equity securities other than common stock are subject to many of the same risks as common stock, although possibly to different degrees. The risks of equity securities are generally magnified in the case of equity investments in distressed companies.

Focused Investment Risk

To the extent that the Fund focuses its investments in a particular sector, it may be susceptible to loss due to adverse developments affecting that sector, including (but not limited to): governmental regulation; inflation; rising interest rates; cost increases in raw materials, fuel and other operating expenses; technological innovations that may render existing products and equipment obsolete; competition from new entrants; high research and development costs; increased costs associated with compliance with environmental or other governmental regulations; and other economic, business or political developments specific to that sector. Furthermore, the Fund may invest a substantial portion of its assets in companies in related sectors that may share common characteristics, are often subject to similar business risks and regulatory burdens, and whose securities may react similarly to the types of developments described above, which will subject the Fund to greater risk. The Fund also will be subject to focused investment risk to the extent that it invests a substantial portion of its assets in a particular issuer, market, asset class, country or geographic region.

162 PIMCO CLOSED-END FUNDS

(Unaudited)

Foreign (Non-U.S.) Investment Risk

Foreign (non-U.S.) securities may experience more rapid and extreme changes in value than securities of U.S. issuers or securities that trade exclusively in U.S. markets. The securities markets of many foreign countries are relatively small, with a limited number of companies representing a small number of industries. Additionally, issuers of foreign (non-U.S.) securities are usually not subject to the same degree of regulation as U.S. issuers. Reporting, accounting, auditing and custody standards of foreign countries differ, in some cases significantly, from U.S. standards. Global economies and financial markets are becoming increasingly interconnected, and conditions and events in one country, region or financial market may adversely impact issuers in a different country, region or financial market. Foreign (non-U.S.) market trading hours, clearance and settlement procedures, and holiday schedules may limit the Fund’s ability to buy and sell securities. Investments in foreign (non-U.S.) markets may also be adversely affected by governmental actions such as the imposition of capital controls, nationalization of companies or industries, expropriation of assets or the imposition of punitive taxes. The governments of certain countries may prohibit or impose substantial restrictions on foreign (non-U.S.) investing in their capital markets or in certain sectors or industries. In addition, a foreign (non-U.S.) government may limit or cause delay in the convertibility or repatriation of its currency which would adversely affect the U.S. dollar value and/or liquidity of investments denominated in that currency. Certain foreign (non-U.S.) investments may become less liquid in response to market developments or adverse investor perceptions, or become illiquid after purchase by the Fund, particularly during periods of market turmoil. A reduction in trading in securities of issuers located in countries whose economies are heavily dependent upon trading with key partners may have an adverse impact on a Fund’s investments.

Also, nationalization, expropriation or confiscatory taxation, unstable governments, decreased market liquidity, currency blockage, market disruptions, political changes, security suspensions or diplomatic developments or the imposition of sanctions or other similar measures could adversely affect the Fund’s investments in a foreign (non-U.S.) country. In the event of nationalization, expropriation or other confiscation, the Fund could lose its entire investment in foreign (non-U.S.) securities. The type and severity of sanctions and other similar measures, including counter sanctions and other retaliatory actions, that may be imposed could vary broadly in scope, and their impact is difficult to ascertain. These types of measures may include, but are not limited to, banning a sanctioned country or certain persons or entities associated with such country from global payment systems that facilitate cross-border payments, restricting the settlement of securities transactions by certain investors, and freezing the assets of

particular countries, entities or persons. The imposition of sanctions and other similar measures could, among other things, result in a decline in the value and/or liquidity of securities issued by the sanctioned country or companies located in or economically tied to the sanctioned country, downgrades in the credit ratings of the sanctioned country’s securities or those of companies located in or economically tied to the sanctioned country, currency devaluation or volatility, and increased market volatility and disruption in the sanctioned country and throughout the world. Sanctions and other similar measures could directly or indirectly limit or prevent a Fund from buying and selling securities (in the sanctioned country and other markets), significantly delay or prevent the settlement of securities transactions, and adversely impact a Fund’s liquidity and performance. Adverse conditions in a certain region can adversely affect securities of other countries whose economies appear to be unrelated. To the extent that the Fund invests a significant portion of its assets in a specific geographic region or in securities denominated in a particular foreign (non-U.S.) currency, the Fund will generally have more exposure to regional economic risks, including weather emergencies and natural disasters, associated with foreign (non-U.S.) investments. Foreign (non-U.S.) securities may also be less liquid (particularly during market closures due to local holidays or other reasons) and more difficult to value than securities of U.S. issuers.

The Fund may invest in securities and instruments that are economically tied to Russia. Investments in Russia are subject to various risks such as, but not limited to political, economic, legal, market and currency risks. The risks include uncertain political and economic policies, short term market volatility, poor accounting standards, corruption and crime, an inadequate regulatory system, regional armed conflict and unpredictable taxation. Investments in Russia are particularly subject to the risk that further economic sanctions, export and import controls, and other similar measures may be imposed by the United States and/or other countries. Other similar measures may include, but are not limited to, banning or expanding bans on Russia or certain persons or entities associated with Russia from global payment systems that facilitate cross-border payments, restricting the settlement of securities transactions by certain investors, and freezing Russian assets or those of particular countries, entities or persons with ties to Russia (e.g. Belarus). Such sanctions and other similar measures — which may impact companies in many sectors, including energy, financial services, technology, accounting, quantum computing, shipping, aviation, metals and mining, defense, architecture, engineering, construction, manufacturing and transportation, among others — and Russia’s countermeasures may negatively impact the Fund’s performance and/or ability to achieve its investment objectives. For example, certain investments may be prohibited and/or existing investments

ANNUAL REPORT | JUNE 30, 2023 163

Principal Risks of the Funds (Cont.)

may become illiquid (e.g., in the event that transacting in certain existing investments is prohibited, securities markets close, or market participants cease transacting in certain investments in light of geopolitical events, sanctions or related considerations), which could render any such securities held by the Fund unmarketable for an indefinite period of time and/or cause the Fund to sell portfolio holdings at a disadvantageous time or price or to continue to hold investments that the Fund no longer seeks to hold. In addition, such sanctions or other similar measures, and the Russian government’s response, could result in a downgrade of Russia’s credit rating or of securities of issuers located in or economically tied to Russia, devaluation of Russia’s currency and/or increased volatility with respect to Russian securities and the ruble. Moreover, disruptions caused by Russian military action or other actions (including cyberattacks, espionage or other asymmetric measures) or resulting actual or threatened responses to such activity may impact Russia’s economy and Russian and other issuers of securities in which the Fund is invested. Such resulting actual or threatened responses may include, but are not limited to, purchasing and financing restrictions, withdrawal of financial intermediaries, boycotts or changes in consumer or purchaser preferences, sanctions, export and import controls, tariffs or cyberattacks on the Russian government, Russian companies or Russian individuals, including politicians. Any actions by Russia made in response to such sanctions or retaliatory measures could further impair the value and liquidity of Fund investments. Sanctions and other similar measures have resulted in defaults on debt obligations by certain corporate issuers and the Russian Federation that could lead to cross-defaults or cross-accelerations on other obligations of these issuers.

The Russian securities market is characterized by limited volume of trading, resulting in difficulty in obtaining accurate prices and trading. These issues can be magnified as a result of sanctions and other similar measures that may be imposed and the Russian government’s response. The Russian securities market, as compared to U.S. markets, has significant price volatility, less liquidity, a smaller market capitalization and a smaller number of traded securities. There may be little publicly available information about issuers. Settlement, clearing and registration of securities transactions are subject to risks. Prior to the implementation of the National Settlement Depository (“NSD”), a recognized central securities depository, there was no central registration system for equity share registration in Russia, and registration was carried out by either the issuers themselves or by registrars located throughout Russia. Title to Russian equities held through the NSD is now based on the records of the NSD and not the registrars. Although the implementation of the NSD has enhanced the efficiency and transparency of the Russian securities market, issues resulting in loss can still occur. In addition, sanctions by the European

Union against the NSD, as well as the potential for sanctions by other governments, could make it more difficult to conduct or confirm transactions involving Russian securities. Ownership of securities issued by Russian companies that are not held through depositories such as the NSD may be recorded by companies themselves and by registrars. In such cases, the risk is increased that the Fund could lose ownership rights through fraud, negligence or oversight. While applicable Russian regulations impose liability on registrars for losses resulting from their errors, it may be difficult for the Fund to enforce any rights it may have against the registrar or issuer of the securities in the event of loss of share registration. In addition, issuers and registrars are still prominent in the validation and approval of documentation requirements for corporate action processing in Russia. Because the documentation requirements and approval criteria vary between registrars and issuers, there remain unclear and inconsistent market standards in the Russian market with respect to the completion and submission of corporate action elections. In addition, sanctions or Russian countermeasures may prohibit or limit a Fund’s ability to participate in corporate actions, and therefore require the Fund to forego voting on or receiving funds that would otherwise be beneficial to the Fund. To the extent that the Fund suffers a loss relating to title or corporate actions relating to its portfolio securities, it may be difficult for the Fund to enforce its rights or otherwise remedy the loss. Russian securities laws may not recognize foreign nominee accounts held with a custodian bank, and therefore the custodian may be considered the ultimate owner of securities they hold for their clients. Adverse currency exchange rates are a risk and there may be a lack of available currency hedging instruments. Investments in Russia may be subject to the risk of nationalization or expropriation of assets. Oil, natural gas, metals, minerals and timber account for a significant portion of Russia’s exports, leaving the country vulnerable to swings in world prices and to sanctions or other actions that may be directed at the Russian economy as a whole or at Russian oil, natural gas, metals, minerals or timber industries.

High Yield Securities Risk

To the extent that the Fund invests in high yield securities and unrated securities of similar credit quality (commonly known as “high yield securities” or “junk bonds”), the Fund may be subject to greater levels of credit risk, call risk and liquidity risk than funds that do not invest in such securities, which could have a negative effect on the NAV and market price of the Fund’s Common Shares or Common Share dividends. These securities are considered predominantly speculative with respect to an issuer’s continuing ability to make principal and interest payments, and may be more volatile than other types of securities. An economic downturn or individual corporate developments could adversely affect the market for these securities and reduce the Fund’s ability to sell these securities at an advantageous time or price. The Fund may purchase

164 PIMCO CLOSED-END FUNDS

(Unaudited)

distressed securities that are in default or the issuers of which are in bankruptcy, which involve heightened risks.

High yield securities structured as zero-coupon bonds or pay-in-kind securities tend to be especially volatile as they are particularly sensitive to downward pricing pressures from rising interest rates or widening spreads and may require the Fund to make taxable distributions of imputed income without receiving the actual cash currency. Issuers of high yield securities may have the right to “call” or redeem the issue prior to maturity, which may result in the Fund having to reinvest the proceeds in other high yield securities or similar instruments that may pay lower interest rates. The Fund may also be subject to greater levels of liquidity risk than funds that do not invest in high yield securities. Consequently, transactions in high yield securities may involve greater costs than transactions in more actively traded securities. A lack of publicly-available information, irregular trading activity and wide bid/ask spreads among other factors, may, in certain circumstances, make high yield debt more difficult to sell at an advantageous time or price than other types of securities or instruments. These factors may result in the Fund being unable to realize full value for these securities and/or may result in the Fund not receiving the proceeds from a sale of a high yield security for an extended period after such sale, each of which could result in losses to the Fund. Because of the risks involved in investing in high yield securities, an investment in the Fund should be considered speculative.

In general, lower rated debt securities carry a greater degree of risk that the issuer will lose its ability to make interest and principal payments, which could have a negative effect on the Fund. Securities of below investment grade quality are regarded as having predominantly speculative characteristics with respect to capacity to pay interest and repay principal and are commonly referred to as “high yield” securities or “junk bonds.” High yield securities involve a greater risk of default and their prices are generally more volatile and sensitive to actual or perceived negative developments. Debt securities in the lowest investment grade category also may be considered to possess some speculative characteristics by certain rating agencies. The Fund may purchase stressed or distressed securities that are in default or the issuers of which are in bankruptcy, which involve heightened risks.

An economic downturn could severely affect the ability of issuers (particularly those that are highly leveraged) to service or repay their debt obligations. Lower-rated securities are generally less liquid than higher-rated securities, which may have an adverse effect on the Fund’s ability to dispose of them. For example, under adverse market or economic conditions, the secondary market for below investment grade securities could contract further, independent of any specific adverse changes in the condition of a particular issuer, and certain

securities in the Fund’s portfolio may become illiquid or less liquid. As a result, the Fund could find it more difficult to sell these securities or may be able to sell these securities only at prices lower than if such securities were widely traded. To the extent the Fund focuses on below investment grade debt obligations, PIMCO’s capabilities in analyzing credit quality and associated risks will be particularly important, and there can be no assurance that PIMCO will be successful in this regard. Due to the risks involved in investing in high yield securities, an investment in the Fund should be considered speculative.

The Fund’s credit quality policies apply only at the time a security is purchased, and the Fund is not required to dispose of a security in the event that a rating agency or PIMCO downgrades its assessment of the credit characteristics of a particular issue. In determining whether to retain or sell such a security, PIMCO may consider factors including, but not limited to, PIMCO’s assessment of the credit quality of the issuer of such security, the price at which such security could be sold and the rating, if any, assigned to such security by other rating agencies. Analysis of creditworthiness may be more complex for issuers of high yield securities than for issuers of higher quality debt securities.

Inflation/Deflation Risk

Inflation risk is the risk that the value of assets or income from the Fund’s investments will be worth less in the future as inflation decreases the value of payments at future dates. As inflation increases, the real value of the Fund’s portfolio could decline. Inflation has increased and it cannot be predicted when, if, or the degree to which it may decline. Deflation risk is the risk that prices throughout the economy decline over time. Deflation may have an adverse effect on the creditworthiness of issuers and may make issuer default more likely, which may result in a decline in the value of the Fund’s portfolio and Common Shares.

Inflation-Indexed Security Risk

Inflation-indexed debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the value of an inflation-indexed security, including Treasury Inflation-Protected Securities (“TIPS”), tends to decrease when real interest rates increase and can increase when real interest rates decrease. Thus generally, during periods of rising inflation, the value of inflation-indexed securities will tend to increase and during periods of deflation, their value will tend to decrease. Interest payments on inflation-indexed securities are unpredictable and will fluctuate as the principal and interest are adjusted for inflation. There can be no assurance that the inflation index used (i.e., the Consumer Price Index (“CPI”)), which is calculated and published by a third-party, will accurately measure the real rate of inflation in the prices of goods and services. Increases in the principal value of TIPS

ANNUAL REPORT | JUNE 30, 2023 165

Principal Risks of the Funds (Cont.)

due to inflation are considered taxable ordinary income for the amount of the increase in the calendar year. Any increase in the principal amount of an inflation-indexed debt security will be considered taxable ordinary income, even though the Fund will not receive the principal until maturity. Additionally, a CPI swap can potentially lose value if the realized rate of inflation over the life of the swap is less than the fixed market implied inflation rate (fixed breakeven rate) that the investor agrees to pay at the initiation of the swap. With municipal inflation-indexed securities, the inflation adjustment is integrated into the coupon payment, which is federally tax exempt (and may be state tax exempt). For municipal inflation-indexed securities, there is no adjustment to the principal value. Because municipal inflation-indexed securities are a small component of the municipal bond market, they may be less liquid than conventional municipal bonds.

Interest Rate Risk

Interest rate risk is the risk that fixed income securities and other instruments in the Fund’s portfolio will fluctuate in value because of a change in interest rates. For example, as nominal interest rates rise, the value of certain fixed income securities held by the Fund is likely to decrease. A nominal interest rate can be described as the sum of a real interest rate and an expected inflation rate. Interest rate changes can be sudden and unpredictable, and the Fund may lose money as a result of movements in interest rates. The Fund may not be able to effectively hedge against changes in interest rates or may choose not to do so for cost or other reasons.

A wide variety of factors can cause interest rates or yields of U.S. Treasury securities (or yields of other types of bonds) to rise, including but not limited to central bank monetary policies, changing inflation or real growth rates, general economic conditions, increasing bond issuances or reduced market demand for low yielding investments. Risks associated with rising interest rates are heightened under current market conditions given that the U.S. Federal Reserve (the “Federal Reserve”) has raised interest rates from historically low levels. In addition, changes in monetary policy may exacerbate the risks associated with changing interest rates. Further, in market environments where interest rates are rising, issuers may be less willing or able to make principal and interest payments on fixed-income investments when due.

Further, fixed income securities with longer durations tend to be more sensitive to changes in interest rates, usually making them more volatile. Duration is a measure used to determine the sensitivity of a security’s price to changes in interest rates that incorporates a security’s yield, coupon, final maturity and call features, among other characteristics. Duration is useful primarily as a measure of the sensitivity of a fixed income security’s market price to interest rate (i.e., yield) movements. All other things remaining equal, for each one

percentage point increase in interest rates, the value of a portfolio of fixed income investments would generally be expected to decline by one percent for every year of the portfolio’s average duration above zero. For example, the value of a portfolio of fixed income securities with an average duration of eight years would generally be expected to decline by approximately 8% if interest rates rose by one percentage point.

Variable and floating rate securities may decline in value if their interest rates do not rise as much, or as quickly, as interest rates in general. Conversely, floating rate securities will not generally increase in value if interest rates decline. Inverse floating rate securities may decrease in value if interest rates increase. Inverse floating rate securities may also exhibit greater price volatility than a fixed rate obligation with similar credit quality. When the Fund holds variable or floating rate securities, a decrease (or, in the case of inverse floating rate securities, an increase) in market interest rates will adversely affect the income received from such securities and the NAV of the Fund’s shares.

During periods of very low or negative interest rates, the Fund may be unable to maintain positive returns. Very low or negative interest rates may magnify interest rate risk. Changing interest rates, including rates that fall below zero, may have unpredictable effects on markets, may result in heightened market volatility and may detract from Fund performance to the extent the Fund is exposed to such interest rates.

Measures such as average duration may not accurately reflect the true interest rate sensitivity of the Fund. This is especially the case if the Fund consists of securities with widely varying durations. Therefore, if the Fund has an average duration that suggests a certain level of interest rate risk, the Fund may in fact be subject to greater interest rate risk than the average would suggest. This risk is greater to the extent the Fund uses leverage or derivatives in connection with the management of the Fund.

Convexity is an additional measure used to understand a security’s or Fund’s interest rate sensitivity. Convexity measures the rate of change of duration in response to changes in interest rates. With respect to a security’s price, a larger convexity (positive or negative) may imply more dramatic price changes in response to changing interest rates. Convexity may be positive or negative. Negative convexity implies that interest rate increases result in increased duration, meaning increased sensitivity in prices in response to rising interest rates. Thus, securities with negative convexity, which may include bonds with traditional call features and certain mortgage-backed securities, may experience greater losses in periods of rising interest rates. Accordingly, if the Fund holds such securities, the Fund may be subject to a greater risk of losses in periods of rising interest rates.

(Unaudited)

Rising interest rates may result in a decline in value of the Fund’s fixed income investments and in periods of volatility. Also, when interest rates rise, issuers are less likely to refinance existing debt securities, causing the average life of such securities to extend. Further, while U.S. bond markets have steadily grown over the past three decades, dealer “market making” ability has remained relatively stagnant. As a result, dealer inventories of certain types of bonds and similar instruments, which provide a core indication of the ability of financial intermediaries to “make markets,” are at or near historic lows in relation to market size. Because market makers provide stability to a market through their intermediary services, a significant reduction in dealer inventories could potentially lead to decreased liquidity and increased volatility in the fixed income markets. Such issues may be exacerbated during periods of economic uncertainty. All of these factors, collectively and/or individually, could cause the Fund to lose value.

Issuer Risk

The value of a security may decline for a number of reasons that directly relate to the issuer, such as management performance, major litigation, investigations or other controversies, changes in financial condition or credit rating, changes in government regulations affecting the issuer or its competitive environment and strategic initiatives such as mergers, acquisitions or dispositions and the market response to any such initiatives, financial leverage or reduced demand for the issuer’s goods or services, as well as the historical and prospective earnings of the issuer and the value of its assets. A change in the financial condition of a single issuer may affect securities markets as a whole. These risks can apply to the Common Shares issued by the Fund and to the issuers of securities and other instruments in which the Fund invests.

Leverage Risk

The Fund’s use of leverage, if any, creates the opportunity for increased Common Share net income, but also creates special risks for Common Shareholders. To the extent used, there is no assurance that the Fund’s leveraging strategies will be successful. Leverage is a speculative technique that may expose the Fund to greater risk and increased costs. The Fund’s assets attributable to leverage, if any, will be invested in accordance with the Fund’s investment objectives and policies. Interest expense payable by the Fund with respect to derivatives and other forms of leverage, and dividends payable with respect to preferred shares outstanding, if any, will generally be based on shorter-term interest rates that would be periodically reset. So long as the Fund’s portfolio investments provide a higher rate of return (net of applicable Fund expenses) than the interest expenses and other costs to the Fund of such leverage, the investment of the proceeds thereof will generate more income than will be needed to pay the costs of the leverage. If so, and all other things being equal, the excess

may be used to pay higher dividends to Common Shareholders than if the Fund were not so leveraged. If, however, shorter-term interest rates rise relative to the rate of return on the Fund’s portfolio, the interest and other costs to the Fund of leverage could exceed the rate of return on the debt obligations and other investments held by the Fund, thereby reducing return to Common Shareholders. Leveraging transactions pursued by the Fund may increase its duration and sensitivity to interest rate movements. In addition, fees and expenses of any form of leverage used by the Fund will be borne entirely by the Common Shareholders (and not by preferred shareholders, if any) and will reduce the investment return of the Common Shares. Therefore, there can be no assurance that the Fund’s use of leverage will result in a higher yield on the Common Shares, and it may result in losses. In addition, any preferred shares issued by the Fund are expected to pay cumulative dividends, which may tend to increase leverage risk. Leverage creates several major types of risks for Common Shareholders, including:

∎  the likelihood of greater volatility of NAV and market price of Common Shares, and of the investment return to Common Shareholders, than a comparable portfolio without leverage;

∎  the possibility either that Common Share dividends will fall if the interest and other costs of leverage rise, or that dividends paid on Common Shares will fluctuate because such costs vary over time; and

∎  the effects of leverage in a declining market or a rising interest rate environment, as leverage is likely to cause a greater decline in the NAV of the Common Shares than if the Fund were not leveraged.

In addition, the counterparties to the Fund’s leveraging transactions and any preferred shareholders of the Fund will have priority of payment over the Fund’s Common Shareholders.

Reverse repurchase agreements involve the risks that the interest income earned on the investment of the proceeds will be less than the interest expense and Fund expenses associated with the repurchase agreement, that the market value of the securities sold by the Fund may decline below the price at which the Fund is obligated to repurchase such securities and that the securities may not be returned to the Fund. There is no assurance that reverse repurchase agreements can be successfully employed. Dollar roll transactions involve the risk that the market value of the securities the Fund is required to purchase may decline below the agreed upon repurchase price of those securities. Successful use of dollar rolls may depend upon the Investment Manager’s ability to correctly predict interest rates and prepayments. There is no assurance that dollar rolls can be successfully employed. In connection with reverse repurchase agreements and dollar rolls, the Fund will also be subject to counterparty risk with

Principal Risks of the Funds (Cont.)

respect to the purchaser of the securities. If the broker/dealer to whom the Fund sells securities becomes insolvent, the Fund’s right to purchase or repurchase securities may be restricted.

The Fund may engage in total return swaps, reverse repurchases, loans of portfolio securities, short sales and when-issued, delayed delivery and forward commitment transactions, credit default swaps, basis swaps and other swap agreements, purchases or sales of futures and forward contracts (including foreign currency exchange contracts), call and put options or other derivatives. The Fund’s use of such transactions gives rise to associated leverage risks described above, and may adversely affect the Fund’s income, distributions and total returns to Common Shareholders. To the extent that any offsetting positions do not behave in relation to one another as expected, the Fund may perform as if it is leveraged through use of these derivative strategies.

Any total return swaps, reverse repurchases, loans of portfolio securities, short sales and when-issued, delayed delivery and forward commitment transactions, credit default swaps, basis swaps and other swap agreements, purchases or sales of futures and forward contracts (including foreign currency exchange contracts), call and put options or other derivatives by the Fund or counterparties to the Fund’s other leveraging transactions, if any, would have seniority over the Fund’s Common Shares.

In addition to preferred shares, the Fund may engage in other transactions that may give rise to a form of leverage including, among others loans of portfolio securities, short sales and when-issued, delayed delivery and forward commitment transactions, credit default swaps, reverse repurchases, or other derivatives. The Fund’s use of such transactions gives rise to associated leverage risks described above, and may adversely affect the Fund’s income, distributions and total returns to Common Shareholders. The Fund may offset derivatives positions against one another or against other assets to manage effective market exposure resulting from derivatives in portfolio. To the extent that any offsetting positions do not behave in relation to one another as expected, the Fund may perform as if it is leveraged through use of these derivative strategies. See “Use of Leverage.”

The Fund is required to satisfy certain regulatory and rating agency asset coverage requirements in connection with its use of preferred shares. Accordingly, any decline in the net asset value of the Fund’s investments could result in the risk that the Fund will fail to meet its asset coverage requirements for any such preferred shares or the risk of the Preferred Shares being downgraded by a rating agency. In an extreme case, the Fund’s current investment income might not be sufficient to meet the dividend requirements on any preferred shares outstanding. In order to address these types of events, the Fund might

need to liquidate investments in order to fund a redemption of some or all of preferred shares. Liquidations at times of adverse economic conditions may result in a loss to the Fund. At other times, these liquidations may result in gain at the Fund level and thus in additional taxable distributions to Common Shareholders. See “Tax Matters” for more information. Any preferred shares of portfolio securities, short sales and when-issued, delayed delivery and forward commitment transactions, credit default swaps, reverse repurchases, or other derivatives by the Fund or counterparties to the Fund’s other leveraging transactions, if any, would have, seniority over the Fund’s Common Shares.

When the Fund issues preferred shares, the Fund pays (and the Common Shareholders bear) all costs and expenses relating to the issuance and ongoing maintenance of preferred shares. In addition, holders of any preferred shares issued by the Fund would have complete priority over Common Shareholders in the distribution of the Fund’s assets. Furthermore, preferred shareholders, voting separately as a single class, have the right to elect two members of the Board at all times and to elect a majority of the trustees in the event two full years’ dividends on the preferred shares are unpaid, and also have separate class voting rights on certain matters. Accordingly, preferred shareholders may have interests that differ from those of Common Shareholders, and may at times have disproportionate influence over the Fund’s affairs.

Because the fees received by the Investment Manager may increase depending on the types of leverage utilized by the Fund,1 the Investment Manager has a financial incentive for the Fund to use certain forms of leverage, which may create a conflict of interest between the Investment Manager, on the one hand, and the Common Shareholders, on the other hand.

Liquidity Risk

Liquidity risk exists when particular investments are difficult to purchase or sell. Illiquid investments are investments that the Fund reasonably expects cannot be sold or disposed of in current market conditions in seven calendar days or less without the sale or disposition significantly changing the market value of the investment. Illiquid investments may become harder to value, especially in changing markets. The Fund’s investments in illiquid investments may reduce the returns of the Fund because it may be unable to sell the illiquid investments at an advantageous time or price or possibly require the Fund to dispose of other investments at unfavorable times or prices in order to satisfy its obligations, which could prevent the Fund from taking advantage of other investment opportunities. Additionally, the market for certain investments may become illiquid under adverse market or economic conditions independent of any specific adverse changes in the conditions of a particular issuer. Bond

markets have consistently grown over the past three decades while the capacity for traditional dealer counterparties to engage in fixed income trading has not kept pace and in some cases has decreased. As a result, dealer inventories of corporate bonds, which provide a core indication of the ability of financial intermediaries to “make markets,” are at or near historic lows in relation to market size. Because market makers seek to provide stability to a market through their intermediary services, the significant reduction in dealer inventories could potentially lead to decreased liquidity and increased volatility in the fixed income markets. Such issues may be exacerbated during periods of economic uncertainty.

In such cases, the Fund, due to regulatory limitations on investments in illiquid investments and the difficulty in purchasing and selling such securities or instruments, may be unable to achieve its desired level of exposure to a certain sector. To the extent that the Fund’s principal investment strategies involve securities of companies with smaller market capitalizations, foreign (non-U.S.) securities, Rule 144A securities, illiquid sectors of fixed income securities, derivatives or securities with substantial market and/or credit risk, the Fund will tend to have the greatest exposure to liquidity risk.

Further, fixed income securities with longer durations until maturity face heightened levels of liquidity risk as compared to fixed income securities with shorter durations until maturity. The risks associated with illiquid instruments may be particularly acute in situations in which the Fund’s operations require cash (such as in connection with repurchase offers) and could result in the Fund borrowing to meet its short-term needs or incurring losses on the sale of illiquid instruments. It may also be the case that other market participants may be attempting to liquidate fixed income holdings at the same time as the Fund, causing increased supply in the market and contributing to liquidity risk and downward pricing pressure.

Liquidity risk also refers to the risk that the Fund may be required to hold additional cash or sell other investments in order to obtain cash to close out derivatives or meet the liquidity demands that derivatives can create to make payments of margin, collateral, or settlement payments to counterparties. The Fund may have to sell a security at a disadvantageous time or price to meet such obligations.

The current direction of governments and regulators may have the effect of reducing market liquidity, market resiliency and money supply, such as through higher rates, tighter financial regulations and proposals related to open-end fund liquidity that may prevent mutual funds and exchange-traded funds from participating in certain markets.

Loans and Other Indebtedness; Loan Participations and Assignments Risk

Loan interests may take the form of (i) direct interests acquired during a primary distribution or (ii) assignments of, novations of or participations in all or a portion of a loan acquired in secondary markets. In addition to credit risk and interest rate risk, the Fund’s exposure to loan interests may be subject to additional risks. For example, purchasers of loans and other forms of direct indebtedness depend primarily upon the creditworthiness of the borrower for payment of principal and interest. Loans are subject to the risk that scheduled interest or principal payments will not be made in a timely manner or at all, either of which may adversely affect the value of the loan. If the Fund does not receive scheduled interest or principal payments on such indebtedness, the Fund’s share price and yield could be adversely affected. Loans that are fully secured may offer the Fund more protection than an unsecured loan in the event of non-payment of scheduled interest or principal if the Fund is able to access and monetize the collateral. However, the collateral underlying a loan, if any, may be unavailable or insufficient to satisfy a borrower’s obligation. If the Fund becomes owner, whole or in part, of any collateral after a loan is foreclosed, the Fund may incur costs associated with owning and/or monetizing its ownership of the collateral.

Moreover, the purchaser of an assignment typically succeeds to all the rights and obligations under the loan agreement with the same rights and obligations as the assigning lender. Assignments may, however, be arranged through private negotiations between potential assignees and potential assignors, and the rights and obligations acquired by the purchaser of an assignment may differ from, and be more limited than, those held by the assigning lender.

Investments in loans through a purchase of a loan, loan origination or a direct assignment of a financial institution’s interests with respect to a loan may involve additional risks to the Fund. For example, if a loan is foreclosed, the Fund could become owner, in whole or in part, of any collateral, which could include, among other assets, real estate or other real or personal property, and would bear the costs and liabilities associated with owning and holding or disposing of the collateral. The purchaser of an assignment typically succeeds to all the rights and obligations under the loan agreement with the same rights and obligations as the assigning lender. Assignments may, however, be arranged through private negotiations between potential assignees and potential assignors, and the rights and obligations acquired by the purchaser of an assignment may differ from, and be more limited than, those held by the assigning lender.

ANNUAL REPORT | JUNE 30, 2023 169

Principal Risks of the Funds (Cont.)

In connection with purchasing loan participations, the Fund generally will have no right to enforce compliance by the borrower with the terms of the loan agreement relating to the loan, nor any rights of set-off against the borrower, and the Fund may not directly benefit from any collateral supporting the loan in which it has purchased the loan participation. As a result, the Fund will be subject to the credit risk of both the borrower and the lender that is selling the participation. In the event of the insolvency of the lender selling a participation, the Fund may be treated as a general creditor of the lender and may not benefit from any set-off between the lender and the borrower. Certain loan participations may be structured in a manner designed to prevent purchasers of participations from being subject to the credit risk of the lender, but even under such a structure, in the event of the lender’s insolvency, the lender’s servicing of the participation may be delayed and the assignability of the participation impaired.

The Fund may have difficulty disposing of loans and loan participations. Because there is no liquid market for many such investments, the Fund anticipates that such investments could be sold only to a limited number of institutional investors. The lack of a liquid secondary market may have an adverse impact on the value of such investments and the Fund’s ability to dispose of particular loans and loan participations when that would be desirable, including in response to a specific economic event such as a deterioration in the creditworthiness of the borrower. The lack of a liquid secondary market for loans and loan participations also may make it more difficult for the Fund to assign a value to these securities for purposes of valuing the Fund’s portfolio.

Investments in loans may include participations in bridge loans, which are loans taken out by borrowers for a short period (typically less than one year) pending arrangement of more permanent financing through, for example, the issuance of bonds, frequently high yield bonds issued for the purpose of acquisitions.

Investments in loans may include acquisitions of, or participation in, delayed funding loans and revolving credit facilities. These commitments may have the effect of requiring the Fund to increase its investment in a borrower at a time when it might not otherwise decide to do so (including at a time when the company’s financial condition makes it unlikely that such amounts will be repaid). Delayed funding loans and revolving credit facilities may be subject to restrictions on transfer, and only limited opportunities may exist to resell such instruments. As a result, a Fund may be unable to sell such investments at an opportune time or may have to resell them at less than fair market value. Further, the Fund may need to hold liquid assets in order to provide funding for these types of commitments, meaning the Fund may not be able to invest in other

attractive investments, or the Fund may need to liquidate existing assets in order to provide such funding.

To the extent the Fund invests in loans, including bank loans, the Fund may be subject to greater levels of credit risk, call risk, settlement risk and liquidity risk. These instruments are considered predominantly speculative with respect to an issuer’s continuing ability to make principal and interest payments and may be more volatile than other types of securities. The Fund may also be subject to greater levels of liquidity risk than funds that do not invest in loans. In addition, the loans in which the Fund invests may not be listed on any exchange and a secondary market for such loans may be comparatively illiquid relative to markets for other more liquid fixed income securities. Consequently, transactions in loans may involve greater costs than transactions in more actively traded securities. In connection with certain loan transactions, transaction costs that are borne by the Fund may include the expenses of third parties that are retained to assist with reviewing and conducting diligence, negotiating, structuring and servicing a loan transaction, and/or providing other services in connection therewith. Furthermore, the Fund may incur such costs in connection with loan transactions that are pursued by the Fund but not ultimately consummated (so-called “broken deal costs”).

Restrictions on transfers in loan agreements, a lack of publicly available information, irregular trading activity and wide bid/ask spreads, among other factors, may, in certain circumstances, make loans more difficult to sell at an advantageous time or price than other types of securities or instruments. These factors may result in the Fund being unable to realize full value for the loans and/or may result in the Fund not receiving the proceeds from a sale of a loan for an extended period after such sale, each of which could result in losses to the Fund. Some loans may have extended trade settlement periods, including settlement periods of greater than seven days, which may result in cash not being immediately available to the Fund. If an issuer of a loan prepays or redeems the loan prior to maturity, the Fund may have to reinvest the proceeds in other loans or similar instruments that may pay lower interest rates. Because of the risks involved in investing in loans, an investment in the Fund should be considered speculative.

The Fund’s investments in subordinated and unsecured loans generally are subject to similar risks as those associated with investments in secured loans. Subordinated or unsecured loans are lower in priority of payment to secured loans and are subject to the additional risk that the cash flow of the borrower and property securing the loan or debt, if any, may be insufficient to meet scheduled payments after giving effect to the senior secured obligations of the borrower. This risk is generally higher for subordinated unsecured loans or debt, which are not backed by a security interest in any specific collateral. Subordinated and unsecured loans generally have greater price

170 PIMCO CLOSED-END FUNDS

(Unaudited)

volatility than secured loans and may be less liquid. There is also a possibility that originators will not be able to sell participations in subordinated or unsecured loans, which would create greater credit risk exposure for the holders of such loans. Subordinate and unsecured loans share the same risks as other below investment grade securities.

There may be less readily available information about most loans and the underlying borrowers than is the case for many other types of securities. Loans may be issued by borrowers that are not subject to SEC reporting requirements and therefore may not be required to file reports with the SEC or may file reports that are not required to comply with SEC form requirements. In addition, such borrowers may be subject to a less stringent liability disclosure regime than companies subject to SEC reporting requirements. Loans may not be considered “securities,” and purchasers, such as the Fund, therefore may not be entitled to rely on the anti-fraud protections of the federal securities laws. Because there is limited public information available regarding loan investments, the Fund is particularly dependent on the analytical abilities of the Fund’s portfolio managers.

Economic exposure to loan interests through the use of derivative transactions may involve greater risks than if the Fund had invested in the loan interest directly during a primary distribution or through assignments of, novations of or participations in a loan acquired in secondary markets since, in addition to the risks described above, certain derivative transactions may be subject to leverage risk and greater illiquidity risk, counterparty risk, valuation risk and other risks.

Management Risk

The Fund is subject to management risk because it is an actively managed investment portfolio. PIMCO and each individual portfolio manager will apply investment techniques and risk analysis in making investment decisions for the Fund, but there can be no guarantee that these decisions will produce the desired results. Certain securities or other instruments in which the Fund seeks to invest may not be available in the quantities desired. In addition, regulatory restrictions, actual or potential conflicts of interest or other considerations may cause PIMCO to restrict or prohibit participation in certain investments. In such circumstances, PIMCO or the individual portfolio managers may determine to purchase other securities or instruments as substitutes. Such substitute securities or instruments may not perform as intended, which could result in losses to the Fund. To the extent the Fund employs strategies targeting perceived pricing inefficiencies, arbitrage strategies or similar strategies, it is subject to the risk that the pricing or valuation of the securities and instruments involved in such strategies may change unexpectedly, which may result in reduced returns or losses to the Fund. Additionally, actual or potential conflicts of interest, legislative, regulatory, or tax restrictions, policies or developments may affect the investment techniques

available to PIMCO and each individual portfolio manager in connection with managing the Fund and may also adversely affect the ability of the Fund to achieve its investment objectives. There also can be no assurance that all of the personnel of PIMCO will continue to be associated with PIMCO for any length of time. The loss of services of one or more key employees of PIMCO could have an adverse impact on the Fund’s ability to realize its investment objectives.

In addition, the Fund may rely on various third-party sources to calculate its NAV. As a result, the Fund is subject to certain operational risks associated with reliance on service providers and service providers’ data sources. In particular, errors or systems failures and other technological issues may adversely impact the Fund’s calculations of its NAV, and such NAV calculation issues may result in inaccurately calculated NAVs, delays in NAV calculation and/or the inability to calculate NAVs over extended periods. The Fund may be unable to recover any losses associated with such failures.

Market Discount Risk

The price of the Fund’s Common Shares will fluctuate with market conditions and other factors. If you sell your Common Shares, the price received may be more or less than your original investment. The Common Shares are designed for long-term investors and should not be treated as trading vehicles. Shares of closed-end management investment companies frequently trade at a discount from their NAV.

Market Disruptions Risk

The Fund is subject to investment and operational risks associated with financial, economic and other global market developments and disruptions, including those arising from war, terrorism, market manipulation, government interventions, defaults and shutdowns, political changes or diplomatic developments, public health emergencies (such as the spread of infectious diseases, pandemics and epidemics) and natural/environmental disasters, which can all negatively impact the securities markets, interest rates, auctions, secondary trading, ratings, credit risk, inflation, deflation, other factors relating to the Fund’s investments or the Investment Manager’s operations and the value of an investment in the Fund, its distributions and its returns. These events can also impair the technology and other operational systems upon which the Fund’s service providers, including PIMCO as the Fund’s investment adviser, rely, and could otherwise disrupt the Fund’s service providers’ ability to fulfill their obligations to the Fund. Furthermore, events involving limited liquidity, defaults, non-performance or other adverse developments that affect financial institutions or the financial services industry generally, or concerns or rumors about any events of these kinds or other similar risks, have in the past and may in the future lead to market-wide liquidity problems.

ANNUAL REPORT | JUNE 30, 2023 171

Principal Risks of the Funds (Cont.)

Market Risk

The market price of securities owned by the Fund may go up or down, sometimes rapidly or unpredictably. Securities may decline in value due to factors affecting securities markets generally or particular industries or issuers represented in the securities markets. The value of a security may decline due to general market conditions that are not specifically related to a particular company, such as real or perceived adverse economic conditions, changes in the general outlook for corporate earnings, changes in interest or currency rates, adverse changes to credit markets or adverse investor sentiment generally. The value of a security may also decline due to factors that affect a particular industry or industries, such as labor shortages or increased production costs and competitive conditions within an industry. During a general downturn in the securities markets, multiple asset classes may decline in value simultaneously. Equity securities generally have greater price volatility than fixed income securities. Credit ratings downgrades may also negatively affect securities held by the Fund. Even when markets perform well, there is no assurance that the investments held by the Fund will increase in value along with the broader market.

In addition, market risk includes the risk that geopolitical and other events will disrupt the economy on a national or global level. For instance, war, terrorism, social unrest, recessions, supply chain disruptions, market manipulation, government defaults, government shutdowns, political changes, diplomatic developments or the imposition of sanctions and other similar measures, public health emergencies (such as the spread of infectious diseases, pandemics and epidemics) and natural/environmental disasters can all negatively impact the securities markets, which could cause the Fund to lose value. These events could reduce consumer demand or economic output, result in market closures, changes in interest rates, inflation/deflation, travel restrictions or quarantines, and significantly adversely impact the economy. The current contentious domestic political environment, as well as political and diplomatic events within the United States and abroad, such as presidential elections in the U.S. or abroad or the U.S. government’s inability at times to agree on a long-term budget and deficit reduction plan, has in the past resulted, and may in the future result, in a government shutdown or otherwise adversely affect the U.S. regulatory landscape, the general market environment and/or investor sentiment, which could have an adverse impact on the Fund’s investments and operations. Additional and/or prolonged U.S. federal government shutdowns may affect investor and consumer confidence and may adversely impact financial markets and the broader economy, perhaps suddenly and to a significant degree. Governmental and quasi-governmental authorities and regulators throughout the world have previously responded to serious economic disruptions with a variety of significant fiscal and monetary policy changes, including but not limited to, direct capital infusions into

companies, new monetary programs and dramatically lower interest rates. An unexpected or sudden reversal of these policies, or the ineffectiveness of these policies, could increase volatility in securities markets, which could adversely affect the Fund’s investments. Any market disruptions could also prevent the Fund from executing advantageous investment decisions in a timely manner. Funds that have focused their investments in a region enduring geopolitical market disruption will face higher risks of loss. Thus, investors should closely monitor current market conditions to determine whether the Fund meets their individual financial needs and tolerance for risk.

Recently, there have been inflationary price movements. As such, fixed income securities markets may experience heightened levels of interest rate, volatility and liquidity risk. As discussed more under “Interest Rate Risk,” the Federal Reserve has begun to raise interest rates from historically low levels and has signaled an intention to continue to do so. Any additional interest rate increases in the future could cause the value of any Fund, such as the Fund, that invests in fixed income securities to decrease.

Although interest rates have significantly increased since 2022 through the date of this report, the prices of real estate-related assets generally have not decreased as much as may be expected based on historical correlations between interest rates and prices of real estate-related assets. This presents an increased risk of a correction or severe downturn in real estate-related asset prices, which could adversely impact the value of other investments as well (such as loans, securitized debt and other fixed income securities). This risk is particularly present with respect to commercial real estate-related asset prices, and the value of other investments with a connection to the commercial real estate sector. As examples of the current risks faced by real estate-related assets: tenant vacancy rates, tenant turnover and tenant concentration have increased; owners of real estate have faced headwinds, delinquencies and difficulties in collecting rents and other payments (which increases the risk of owners being unable to pay or otherwise defaulting on their own borrowings and obligations); property values have declined; inflation, upkeep costs and other expenses have increased; and rents have declined for many properties.

Exchanges and securities markets may close early, close late or issue trading halts on specific securities, which may result in, among other things, the Fund being unable to buy or sell certain securities or financial instruments at an advantageous time or accurately price its portfolio investments.

Mortgage-Related and Other Asset-Backed Instruments Risk

The mortgage-related assets in which the Fund may invest include, but are not limited to, any security, instrument or other asset that is

172 PIMCO CLOSED-END FUNDS

(Unaudited)

related to U.S. or non-U.S. mortgages, including those issued by private originators or issuers, or issued or guaranteed as to principal or interest by the U.S. government or its agencies or instrumentalities or by non-U.S. governments or authorities, such as, without limitation, assets representing interests in, collateralized or backed by, or whose values are determined in whole or in part by reference to any number of mortgages or pools of mortgages or the payment experience of such mortgages or pools of mortgages, including REMICs, which could include Re-REMICs, mortgage pass-through securities, inverse floaters, CMOs, CLOs, multiclass pass-through securities, private mortgage pass-through securities, stripped mortgage securities (generally interest-only and principal-only securities), mortgage-related asset backed securities and mortgage-related loans (including through participations, assignments, originations and whole loans), including commercial and residential mortgage loans. Exposures to mortgage-related assets through derivatives or other financial instruments will be considered investments in mortgage-related assets.

The Fund may also invest in other types of ABS, including CDOs, CBOs and CLOs and other similarly structured securities.

Mortgage-related and other asset-backed instruments represent interests in “pools” of mortgages or other assets such as consumer loans or receivables held in trust and often involve risks that are different from or possibly more acute than risks associated with other types of debt instruments. Generally, rising interest rates tend to extend the duration of fixed rate mortgage-related assets, making them more sensitive to changes in interest rates. Compared to other fixed income investments with similar maturity and credit, mortgage-related securities may increase in value to a lesser extent when interest rates decline and may decline in value to a similar or greater extent when interest rates rise. As a result, in a period of rising interest rates, the Fund may exhibit additional volatility since individual mortgage holders are less likely to exercise prepayment options, thereby putting additional downward pressure on the value of these securities and potentially causing the Fund to lose money. This is known as extension risk. Mortgage-backed securities can be highly sensitive to rising interest rates, such that even small movements can cause the Fund to lose value. Mortgage-backed securities, and in particular those not backed by a government guarantee, are subject to credit risk. When interest rates decline, borrowers may pay off their mortgages sooner than expected. This can reduce the returns of the Fund because the Fund may have to reinvest that money at the lower prevailing interest rates. The Fund’s investments in other asset-backed instruments are subject to risks similar to those associated with mortgage-related assets, as well as additional risks associated with the nature of the assets and the servicing of those assets. Payment of principal and

interest on asset-backed instruments may be largely dependent upon the cash flows generated by the assets backing the instruments, and asset-backed instruments may not have the benefit of any security interest in the related assets.

Subordinate mortgage-backed or asset-backed instruments are paid interest only to the extent that there are funds available to make payments. To the extent the collateral pool includes a large percentage of delinquent loans, there is a risk that interest payments on subordinate mortgage-backed or asset-backed instruments will not be fully paid.

There are multiple tranches of mortgage-backed and asset-backed instruments, offering investors various maturity and credit risk characteristics. Tranches are categorized as senior, mezzanine, and subordinated/equity or “first loss,” according to their degree of risk. The most senior tranche of a mortgage-backed or asset-backed instrument has the greatest collateralization and pays the lowest interest rate. If there are defaults or the collateral otherwise underperforms, scheduled payments to senior tranches take precedence over those of mezzanine tranches, and scheduled payments to mezzanine tranches take precedence over those to subordinated/equity tranches. Lower tranches represent lower degrees of credit quality and pay higher interest rates intended to compensate for the attendant risks. The return on the lower tranches is especially sensitive to the rate of defaults in the collateral pool. The lowest tranche (i.e., the “equity” or “residual” tranche) specifically receives the residual interest payments (i.e., money that is left over after the higher tranches have been paid and expenses of the issuing entities have been paid) rather than a fixed interest rate. The Fund may also invest in the residual or equity tranches of mortgage-related and other asset-backed instruments, which may be referred to as subordinate mortgage-backed or asset-backed instruments and interest-only mortgage-backed or asset-backed instruments. The Fund expects that investments in subordinate mortgage-backed and other asset-backed instruments will be subject to risks arising from delinquencies and foreclosures, thereby exposing its investment portfolio to potential losses. The Fund expects that investments in the lowest tranche of or subordinate mortgage-backed and other asset-backed instruments will be subject to the greatest risks of losing part or all of their values, which could arise from delinquencies and foreclosures, thereby exposing the Fund’s investment portfolio to potential losses. Subordinate securities of mortgage-backed and other asset-backed instruments are also subject to greater credit risk than those mortgage-backed or other asset-backed instruments that are more highly rated.

The mortgage markets in the United States and in various foreign countries have experienced extreme difficulties in the past that

ANNUAL REPORT | JUNE 30, 2023 173

Principal Risks of the Funds (Cont.)

adversely affected the performance and market value of certain of the Fund’s mortgage-related investments. Delinquencies and losses on residential and commercial mortgage loans (especially subprime and second-lien mortgage loans) may increase, and a decline in or flattening of housing and other real property values may exacerbate such delinquencies and losses. In addition, reduced investor demand for mortgage loans and mortgage-related securities and increased investor yield requirements have caused limited liquidity in the secondary market for mortgage-related securities, which can adversely affect the market value of mortgage-related securities. It is possible that such limited liquidity in such secondary markets could continue or worsen.

With respect to risk retention tranches (i.e., eligible residual interests initially held by the sponsors of CMBS and other eligible securitizations pursuant to the U.S. Risk Retention Rules), a third-party purchaser, such as the Fund, must hold its retained interest, unhedged, for at least five year following the closing of the CMBS transaction, after which it is entitled to transfer its interest in the securitization to another person that meets the requirements for a third-party purchaser. Even after the required holding period has expired, due to the generally illiquid nature of such investments, no assurance can be given as to what, if any, exit strategies will ultimately be available for any given position.

In addition, there is limited guidance on the application of the Final U.S. Risk Retention Rules to specific securitization structures. There can be no assurance that the applicable federal agencies charged with the implementation of the Final U.S. Risk Retention Rules (the FDIC, the Comptroller of the Currency, the Federal Reserve Board, the SEC, the Department of Housing and Urban Development, and the Federal Housing Finance Agency) could not take positions in the future that differ from the interpretation of such rules taken or embodied in such securitizations, or that the Final U.S. Risk Retention Rules will not change.

Furthermore, in situations where the Fund invests in risk retention tranches of securitizations structured by third parties, the Fund may be required to execute one or more letters or other agreements, the exact form and nature of which will vary (each, a “Risk Retention Agreement”) under which it will make certain undertakings designed to ensure such securitization complies with the U.S. Risk Retention Rules. Such Risk Retention Agreements may include a variety of representations, warranties, covenants and other indemnities, each of which may run to various transaction parties. If the Fund breaches any undertakings in any Risk Retention Agreement, it will be exposed to claims by the other parties thereto, including for any losses incurred as a result of such breach, which could be significant and exceed the value of the Fund’s investments.

Mortgage-Related Derivative Instruments Risk

The Fund may engage in derivative transactions related to mortgage-backed securities, including purchasing and selling exchange-listed and OTC put and call options, futures and forwards on mortgages and mortgage-backed securities. The Fund may also invest in mortgage-backed securities credit default swaps, which include swaps the reference obligation for which is a mortgage-backed security or related index, such as the CMBX Index (a tradeable index referencing a basket of commercial mortgage-backed securities), the TRX Index (a tradeable index referencing total return swaps based on commercial mortgage-backed securities) or the ABX (a tradeable index referencing a basket of sub-prime mortgage-backed securities). The Fund may invest in newly developed mortgage related derivatives that may hereafter become available.

Derivative mortgage-backed securities (such as principal-only (“POs”), interest-only (“IOs”) or inverse floating rate securities) are particularly exposed to call and extension risks. Small changes in mortgage prepayments can significantly impact the cash flows and the market value of these derivative instruments. In general, the risk of faster than anticipated prepayments adversely affects IOs, super floaters and premium priced mortgage-backed securities. The risk of slower than anticipated prepayments generally affects POs, floating-rate securities subject to interest rate caps, support tranches and discount priced mortgage-backed securities. In addition, particular derivative instruments may be leveraged such that their exposure (i.e., price sensitivity) to interest rate and/or prepayment risk is magnified.

Mortgage-related derivative instruments involve risks associated with mortgage-related and other asset-backed instruments, privately-issued mortgage-related securities, the mortgage market, the real estate industry, derivatives and credit default swaps.

Operational Risk

An investment in the Fund, like any fund, can involve operational risks arising from factors such as processing errors, human errors, inadequate or failed internal or external processes, failures in systems and technology, changes in personnel and errors caused by third-party service providers. The occurrence of any of these failures, errors or breaches could result in a loss of information, regulatory scrutiny, reputational damage or other events, any of which could have a material adverse effect on the Fund. While the Fund seeks to minimize such events through controls and oversight, there may still be failures that could cause losses to the Fund.

Other Investment Companies Risk

When investing in an investment company, the Fund will generally bear its ratable share of that investment company’s expenses and would remain subject to payment of the Fund’s management fees and other expenses with respect to assets so invested. Common Shareholders

174 PIMCO CLOSED-END FUNDS

(Unaudited)

would therefore be subject to duplicative expenses to the extent the Fund invests in other investment companies. In addition, the securities of other investment companies may also be leveraged and will therefore be subject to same leverage risks.

Platform Risk

The Alt Lending ABS in which the Fund may invest are typically not listed on any securities exchange and not registered under the Securities Act. In addition, the Fund anticipates that these instruments may only be sold to a limited number of investors and may have a limited or non-existent secondary market. Accordingly, the Fund currently expects that certain of the investments it may make in Alt Lending ABS will face heightened levels of liquidity risk. Although currently there is generally no reliable, active secondary market for certain Alt Lending ABS, a secondary market for these Alt Lending ABS may develop. If the Fund purchases Alt Lending ABS on an alternative lending platform, the Fund will have the right to receive principal and interest payments due on loans underlying the Alt Lending ABS only if the platform servicing the loans receives the borrower’s payments on such loans and passes such payments through to the Fund. If a borrower is unable or fails to make payments on a loan for any reason, the Fund may be greatly limited in its ability to recover any outstanding principal or interest due, as (among other reasons) the Fund may not have direct recourse against the borrower or may otherwise be limited in its ability to directly enforce its rights under the loan, whether through the borrower or the platform through which such loan was originated, the loan may be unsecured or under-collateralized and/or it may be impracticable to commence a legal proceeding against the defaulting borrower.

The Fund may have limited knowledge about the underlying loans and is dependent upon the platform for information regarding underlying loans. Although PIMCO may conduct diligence on the platforms, the Fund generally does not have the ability to independently verify the information provided by the platforms, other than payment information regarding loans underlying the Alt Lending ABS owned by the Fund, which the Fund observes directly as payments are received. With respect to Alt Lending ABS that the Fund purchases in the secondary market (i.e., not directly from an alternative lending platform), the Fund may not perform the same level of diligence on such platform or at all. The Fund may not review the particular characteristics of the loans collateralizing an Alt Lending ABS, but rather negotiate in advance with platforms the general criteria of the underlying loans. As a result, the Fund is dependent on the platforms’ ability to collect, verify and provide information to the Fund about each loan and borrower.

The Fund relies on the borrower’s credit information, which is provided by the platforms. However, such information may be out of date,

incomplete or inaccurate and may, therefore, not accurately reflect the borrower’s actual creditworthiness. Platforms may not have an obligation to update borrower information, and, therefore, the Fund may not be aware of any impairment in a borrower’s creditworthiness subsequent to the making of a particular loan. The platforms’ credit decisions and scoring models may be based on algorithms that could potentially contain programming or other errors or prove to be ineffective or otherwise flawed. This could adversely affect loan pricing data and approval processes and could cause loans to be mispriced or misclassified, which could ultimately have a negative impact on the Fund’s performance.

In addition, the underlying loans, in some cases, may be affected by the success of the platforms through which they are facilitated.

Therefore, disruptions in the businesses of such platforms may also negatively impact the value of the Fund’s investments. In addition, disruption in the business of a platform could limit or eliminate the ability of the Fund to invest in loans originated by that platform, and therefore the Fund could lose some or all of the benefit of its diligence effort with respect to that platform.

Platforms are for-profit businesses that, as a general matter, generate revenue by collecting fees on funded loans from borrowers and by assessing a loan servicing fee on investors, which may be a fixed annual amount or a percentage of the loan or amounts collected. This business could be disrupted in multiple ways; for example, a platform could file for bankruptcy or a platform might suffer reputational harm from negative publicity about the platform or alternative lending more generally and the loss of investor confidence in the event that a loan facilitated through the platform is not repaid and the investor loses money on its investment. Many platforms and/or their affiliates have incurred operating losses since their inception and may continue to incur net losses in the future, particularly as their businesses grow and they incur additional operating expenses. Platforms may also be forced to defend legal action taken by regulators or governmental bodies. Alternative lending is a newer industry operating in an evolving legal environment. Platforms may be subject to risk of litigation alleging violations of law and/or regulations, including, for example, consumer protection laws, whether in the U.S. or in foreign jurisdictions. Platforms may be unsuccessful in defending against such lawsuits or other actions and, in addition to the costs incurred in fighting any such actions, platforms may be required to pay money in connection with the judgments, settlements or fines or may be forced to modify the terms of its borrower loans, which could cause the platform to realize a loss or receive a lower return on a loan than originally anticipated. Platforms may also be parties to litigation or other legal action in an attempt to protect or enforce their rights or those of affiliates, including intellectual property rights, and may incur similar costs in

ANNUAL REPORT | JUNE 30, 2023 175

Principal Risks of the Funds (Cont.)

connection with any such efforts. The Fund’s investments in Alt Lending ABS may expose the Fund to the credit risk of the issuer. Generally, such instruments are unsecured obligations of the issuer; an issuer that becomes subject to bankruptcy proceedings may be unable to make full and timely payments on its obligations to the Fund, even if the payments on the underlying loan or loans continue to be made timely and in full. In addition, when the Fund owns Alt Lending ABS, the Fund and its custodian generally does not have a contractual relationship with, or personally identifiable information regarding, individual borrowers, so the Fund will not be able to enforce underlying loans directly against borrowers and may not be able to appoint an alternative servicing agent in the event that a platform or third-party servicer, as applicable, ceases to service the underlying loans. Therefore, the Fund is more dependent on the platform for servicing than if the Fund had owned whole loans through the platform. Where such interests are secured, the Fund relies on the platform to perfect the Fund’s security interest. In addition, there may be a delay between the time the Fund commits to purchase an instrument issued by a platform, its affiliate or a special purpose entity sponsored by the platform or its affiliate and the issuance of such instrument and, during such delay, the funds committed to such an investment will not earn interest on the investment nor will they be available for investment in other alternative lending-related instruments, which will reduce the effective rate of return on the investment. The Fund’s investments in Alt Lending ABS may be illiquid.

Portfolio Turnover Risk

The Investment Manager manages the Fund without regard generally to restrictions on portfolio turnover. The use of futures contracts and other derivative instruments with relatively short maturities may tend to exaggerate the portfolio turnover rate for the Fund. Trading in fixed income securities does not generally involve the payment of brokerage commissions but does involve indirect transaction costs. The use of futures contracts and other derivative instruments may involve the payment of commissions to futures commission merchants or other intermediaries. Higher portfolio turnover involves correspondingly greater expenses to the Fund, including brokerage commissions or dealer mark-ups and other transaction costs on the sale of securities and reinvestments in other securities. The higher the rate of portfolio turnover of the Fund, the higher these transaction costs borne by the Fund generally will be. Such sales may result in realization of taxable capital gains (including short-term capital gains, which are generally taxed to shareholders at ordinary income tax rates when distributed net of short-term capital losses and net long-term capital losses) and may adversely impact the Fund’s after-tax returns.

Potential Conflicts of Interest Risk — Allocation of Investment Opportunities

The Investment Manager and its affiliates are involved worldwide with a broad spectrum of financial services and asset management activities and may engage in the ordinary course of business in activities in which their interests or the interests of their clients may conflict with those of the Fund. The Investment Manager may provide investment management services to other funds and discretionary managed accounts that follow an investment program similar to that of the Fund. Subject to the requirements of the 1940 Act, the Investment Manager intends to engage in such activities and may receive compensation from third parties for its services. The results of the Fund’s investment activities may differ from those of the Fund’s affiliates, or another account managed by the Investment Manager or its affiliates, and it is possible that the Fund could sustain losses during periods in which one or more of the Fund’s affiliates and/or other accounts managed by the Investment Manager or its affiliates, including proprietary accounts, achieve profits on their trading.

Preferred Securities Risk

In addition to equity securities risk, credit risk and possibly high yield risk, investment in preferred securities involves certain other risks. Certain preferred securities contain provisions that allow an issuer under certain conditions to skip or defer distributions. If the Fund owns a preferred security that is deferring its distribution, the Fund may be required to include the amount of the deferred distribution in its taxable income for tax purposes although it does not currently receive such amount in cash. In order to receive the special treatment accorded to regulated investment companies and their shareholders under the Internal Revenue Code of 1986, as amended (the “Code”) and to avoid U.S. federal income and/or excise taxes at the Fund level, the Fund may be required to distribute this income to shareholders in the tax year in which the income is recognized (without a corresponding receipt of cash). Therefore, the Fund may be required to pay out as an income distribution in any such tax year an amount greater than the total amount of cash income the Fund actually received and to sell portfolio securities, including at potentially disadvantageous times or prices, to obtain cash needed for these income distributions. Preferred securities often are subject to legal provisions that allow for redemption in the event of certain tax or legal changes or at the issuer’s call. In the event of redemption, the Fund may not be able to reinvest the proceeds at comparable rates of return. Preferred securities are subordinated to bonds and other debt securities in an issuer’s capital structure in terms of priority for corporate income and liquidation payments, and therefore will be subject to greater credit risk than those debt securities. Preferred securities may trade less frequently and in a more limited volume and may be subject to more abrupt or erratic price movements than many other securities.

176 PIMCO CLOSED-END FUNDS

(Unaudited)

Additional Risks Associated with the Fund’s Preferred Shares

Although the Fund’s ARPS ordinarily would pay dividends at rates set at periodic auctions, the weekly auctions for the ARPS (and auctions for similar preferred shares issued by closed-end funds in the U.S.) have failed since 2008. The dividend rates on the ARPS since that time have been paid, and the Fund expects that they will continue to be paid for the foreseeable future, at the “maximum applicable rate” under the Fund’s Bylaws (i.e., the greater of a multiple of or a spread plus a reference rate). An increase in market interest rates generally, therefore, could increase substantially the dividend rate required to be paid by the Fund to the holders of ARPS, which would increase the costs associated with the Fund’s leverage and reduce the Fund’s net income available for distribution to Common Shareholders. In addition, the multiple or spread used to calculate the maximum applicable rate is based in part on the credit rating assigned to the ARPS by the applicable rating agency(ies), with the multiple or spread generally increasing as the rating declines. The Fund’s ARPS rating has previously been downgraded and the ARPS could be subject to further ratings downgrades in the future, possibly resulting in further increases to the maximum applicable rate.

Therefore, it is possible that a substantial rise in market interest rates and/or further ratings downgrades of the ARPS could, by reducing income available for distribution to the Common Shareholders and otherwise detracting from the Fund’s investment performance, make the Fund’s continued use of Preferred Shares for leverage purposes less attractive than such use is currently considered to be. In such case, the Fund may elect to redeem some or all of the Preferred Shares outstanding, which may require it to dispose of investments at inopportune times and to incur losses on such dispositions. Such dispositions may adversely affect the Fund’s investment performance generally, and the resultant loss of leverage may materially and adversely affect the Fund’s investment returns to Common Shareholders. The Fund has previously been required to redeem a portion of its ARPS due to market dislocations that caused the value of the Fund’s portfolio securities and related asset coverage to decline and could be required to do so again in the future.

The Fund is also subject to certain asset coverage tests associated with the rating agencies that rate the ARPS. Failure by the Fund to maintain the asset coverages (or to cure such failure in a timely manner) may require the Fund to redeem ARPS. Failure to satisfy ratings agency asset coverage tests or other guidelines could also result in the applicable ratings agency downgrading its then-current ratings on the ARPS, as described above. Moreover, the rating agency guidelines impose restrictions or limitations on the Fund’s use of certain financial instruments or investment techniques that the Fund might otherwise utilize in order to achieve its investment objective, which may adversely affect the Fund’s investment performance. Rating agency

guidelines may be modified by the rating agencies in the future and such modifications may make such guidelines substantially more restrictive or otherwise result in downgrades, which could further negatively affect the Fund’s investment performance.

As discussed further in “Notes to Financial Statements — Auction-Rate Preferred Shares”, on December 4, 2020, Fitch published revised ratings criteria relating to closed-end fund obligations, including preferred shares, which effectively result in a rating cap of “A” for the Fund. Following the close of business on April 30, 2021, Fitch downgraded its rating of the Fund’s ARPS from “AA” to “A” pursuant to the revised ratings methodology and related new rating caps. With respect to PIMCO Corporate & Income Strategy Fund, under the Fund’s Bylaws, the April 2021 Fitch downgrade resulted in an increase in the multiple used to calculate the maximum applicable rate from 150% to 160%, thereby increasing the dividend rate payable to the Fund’s ARPS holders and increasing the expenses to the Common Shareholders associated with the Fund’s leverage. In December 2022, Moody’s downgraded its rating of the PCN ARPS, PFL ARPS and PFN ARPs from “Aa3” to “A1,” stating that the downgrades occurred because of, among other matters, trends in each respective Fund’s risk-adjusted asset coverage metrics and the evolution of its sector exposures. With respect to each of PIMCO Income Strategy Fund and PIMCO Income Strategy Fund II, under each Fund’s Bylaws, the April 2021 Fitch downgrade resulted in an increase in the dividend rate multiplier from 1.50 to 2.00, which could increase the dividend rate payable to each Fund’s ARPS holders should the maximum dividend rate be determined via the multiplier in lieu of the spread noted above (the maximum dividend rate is based on the greater of a multiple of or a spread plus a reference rate) and, thereby, increase the expenses to Common Shareholders associated with the Fund’s leverage.

Privacy and Data Security Risk

The Gramm-Leach-Bliley Act (“GLBA”) and other laws limit the disclosure of certain non-public personal information about a consumer to non- affiliated third parties and require financial institutions to disclose certain privacy policies and practices with respect to information sharing with both affiliates and non- affiliated third parties. Many states and a number of non-U.S. jurisdictions have enacted privacy and data security laws requiring safeguards on the privacy and security of consumers’ personally identifiable information. Other laws deal with obligations to safeguard and dispose of private information in a manner designed to avoid its dissemination. Privacy rules adopted by the U.S. Federal Trade Commission and SEC implement GLBA and other requirements and govern the disclosure of consumer financial information by certain financial institutions, ranging from banks to private investment funds. U.S. platforms following certain models generally are required to have privacy policies that conform to these GLBA and other requirements. In addition, such

ANNUAL REPORT | JUNE 30, 2023 177

Principal Risks of the Funds (Cont.)

platforms typically have policies and procedures intended to maintain platform participants’ personal information securely and dispose of it properly.

The Fund generally does not intend to obtain or hold borrowers’ non-public personal information, and the Fund has implemented procedures designed to prevent the disclosure of borrowers’ non-public personal information to the Fund. However, service providers to the Fund, or its direct or indirect fully-owned subsidiaries, including their custodians and the platforms acting as loan servicers for the Fund or its direct or indirect fully-owned subsidiaries, may obtain, hold or process such information. The Fund cannot guarantee the security of non-public personal information in the possession of such a service provider and cannot guarantee that service providers have been and will continue to comply with the GLBA, other data security and privacy laws and any other related regulatory requirements. Violations of the GLBA and other laws could subject the Fund to litigation and/or fines, penalties or other regulatory action, which, individually or in the aggregate, could have an adverse effect on the Fund. The Fund may also face regulations related to privacy and data security in the other jurisdictions in which the Fund invests.

Private Placements and Restricted Securities Risk

A private placement involves the sale of securities that have not been registered under the 1933 Act, or relevant provisions of applicable non-U.S. law, to certain institutional and qualified individual purchasers, such as the Fund. In addition to the general risks to which all securities are subject, securities received in a private placement generally are subject to strict restrictions on resale, and there may be no liquid secondary market or ready purchaser for such securities. Therefore, the Fund may be unable to dispose of such securities when it desires to do so, or at the most favorable time or price. Private placements may also raise valuation risks.

Restricted securities are often purchased at a discount from the market price of unrestricted securities of the same issuer reflecting the fact that such securities may not be readily marketable without some time delay. Such securities are often more difficult to value and the sale of such securities often requires more time and results in higher brokerage charges or dealer discounts and other selling expenses than does the sale of securities trading on national securities exchanges or in the over-the-counter markets. Until the Fund can sell such securities into the public markets, its holdings may be less liquid and any sales will need to be made pursuant to an exemption under the Securities Act.

Privately Issued Mortgage-Related Securities Risk

There are no direct or indirect government or agency guarantees of payments in pools created by non-governmental issuers. Privately-issued mortgage-related securities are also not subject to the same

underwriting requirements for the underlying mortgages that are applicable to those mortgage-related securities that have a government or government-sponsored entity guarantee.

Privately-issued mortgage-related securities are not traded on an exchange and there may be a limited market for the securities, especially when there is a perceived weakness in the mortgage and real estate market sectors. Without an active trading market, mortgage-related securities held in the Fund’s portfolio may be particularly difficult to value because of the complexities involved in assessing the value of the underlying mortgage loans.

Real Estate Risk

To the extent that the Fund invests in real estate investments, including investments in equity or debt securities issued by private and public REITs, real estate operating companies (“REOCs”), private or public real estate-related loans and real estate-linked derivative instruments, it will be subject to the risks associated with owning real estate and with the real estate industry generally. These risks include, but are not limited to: the burdens of ownership of real property; general and local economic conditions (such as an oversupply of space or a reduction in demand for space); the supply and demand for properties (including competition based on rental rates); energy and supply shortages; fluctuations in average occupancy and room rates; the attractiveness, type and location of the properties and changes in the relative popularity of commercial properties as an investment; the financial condition and resources of tenants, buyers and sellers of properties; increased mortgage defaults; the quality of maintenance, insurance and management services; changes in the availability of debt financing which may render the sale or refinancing of properties difficult or impracticable; changes in building, environmental and other laws and/or regulations (including those governing usage and improvements), fiscal policies and zoning laws; changes in real property tax rates; changes in interest rates and the availability of mortgage funds which may render the sale or refinancing of properties difficult or impracticable; changes in operating costs and expenses; energy and supply shortages; uninsured losses or delays from casualties or condemnation; negative developments in the economy that depress travel or leasing activity; environmental liabilities; contingent liabilities on disposition of assets; uninsured or uninsurable casualties; acts of God, including earthquakes, hurricanes and other natural disasters; social unrest and civil disturbances, epidemics, pandemics or other public crises; terrorist attacks and war; risks and operating problems arising out of the presence of certain construction materials, structural or property level latent defects, work stoppages, shortages of labor, strikes, union relations and contracts, fluctuating prices and supply of labor and/or other labor-related factor; and other factors which are beyond the control of PIMCO and its affiliates.

(Unaudited)

In addition, the Fund’s investments will be subject to various risks which could cause fluctuations in occupancy, rental rates, operating income and expenses or which could render the sale or financing of its properties difficult or unattractive. For example, following the termination or expiration of a tenant’s lease, there may be a period of time before receiving rental payments under a replacement lease. During that period, the Fund would continue to bear fixed expenses such as interest, real estate taxes, maintenance and other operating expenses. In addition, declining economic conditions may impair the ability to attract replacement tenants and achieve rental rates equal to or greater than the rents paid under previous leases. Increased competition for tenants may require capital improvements to properties which would not have otherwise been planned.

Ultimately, to the extent it is not possible to renew leases or re-let space as leases expire, decreased cash flow from tenants will result, which could adversely impact the Fund’s operating results.

Real estate values have historically been cyclical. As the general economy grows, demand for real estate increases and occupancies and rents may increase. As occupancies and rents increase, property values increase, and new development occurs. As development may occur, occupancies, rents and property values may decline. Because leases are usually entered into for long periods and development activities often require extended times to complete, the real estate value cycle often lags the general business cycle. Because of this cycle, real estate companies may incur large swings in their profits and the prices of their securities. Developments following the onset of COVID-19 have adversely impacted certain commercial real estate markets, causing the deferral of mortgage payments, renegotiated commercial mortgage loans, commercial real estate vacancies or outright mortgage defaults, and potential acceleration of macro trends such as work from home and online shopping which may negatively impact certain industries, such as brick-and-mortar retail.

The total returns available from investments in real estate generally depend on the amount of income and capital appreciation generated by the related properties. The performance of real estate, and thereby the Fund, will be reduced by any related expenses, such as expenses paid directly at the property level and other expenses that are capitalized or otherwise embedded into the cost basis of the real estate.

Separately, certain service providers to the Fund and/or its subsidiaries, as applicable, with respect to its real state or real estate-related investments are expected to be, or are owned by, employed by, or otherwise related to, PIMCO, Allianz SE, their affiliates and/or their respective employees, consultants and other personnel. PIMCO may, in its sole discretion, determine to provide, or engage or recommend an

affiliate of PIMCO to provide, certain services to the Fund, instead of engaging or recommending one or more third parties to provide such services. Subject to the governance requirements of a particular fund and applicable law, PIMCO or its affiliates, as applicable, will receive compensation in connection with the provision of such services. As a result, PIMCO faces a conflict of interest when selecting or recommending service providers for the Fund. Fees paid to an affiliated service provider will be determined in PIMCO’s commercially reasonable discretion. Although PIMCO has adopted various policies and procedures intended to mitigate or otherwise manage conflicts of interest with respect to affiliated service providers, there can be no guarantee that such policies and procedures (which may be modified or terminated at any time in PIMCO’s sole discretion) will be successful.

Regulation S Securities Risk

Regulation S securities are offered through off-shore (non-U.S.) offerings without registration with the SEC pursuant to Regulation S of the Securities Act. Because Regulation S securities are subject to legal or contractual restrictions on resale, Regulation S securities may be considered illiquid. Furthermore, because Regulation S securities are generally less liquid than registered securities, a Fund may take longer to liquidate these positions than would be the case for publicly traded securities. Although Regulation S securities may be resold in privately negotiated transactions, the price realized from these sales could be less than off-shore transactions or in those originally paid by the Fund. Further, companies whose securities are not publicly traded may not be subject to the disclosure and other investor protection requirements that would be applicable if their securities were publicly traded. Accordingly, Regulation S securities may involve a high degree of business and financial risk and may result in substantial losses.

Regulatory Changes Risk

Financial entities, such as investment companies and investment advisers, are generally subject to extensive government regulation and intervention. Government regulation and/or intervention may change the way the Fund is regulated, affect the expenses incurred directly by the Fund and the value of its investments, and limit and /or preclude the Fund’s ability to achieve its investment objective. Government regulation may change frequently and may have significant adverse consequences. The Fund and the Investment Manager have historically been eligible for exemptions from certain regulations. However, there is no assurance that the Fund and the Investment Manager will continue to be eligible for such exemptions. Actions by governmental entities may also impact certain instruments in which the Fund invests.

Moreover, government regulation may have unpredictable and unintended effects. Legislative or regulatory actions to address

ANNUAL REPORT | JUNE 30, 2023 179

Principal Risks of the Funds (Cont.)

perceived liquidity or other issues in fixed income markets generally, or in particular markets such as the municipal securities market, may alter or impair the Fund’s ability to pursue its investment objectives or utilize certain investment strategies and techniques.

Regulatory Risk — Commodity Pool Operator

The CFTC has adopted regulations that subject registered investment companies and their investment advisers to regulation by the CFTC if the registered investment company invests more than a prescribed level of its liquidation value in futures, options on futures or commodities, swaps, or other financial instruments regulated under the CEA and the rules thereunder (“commodity interests”), or if the Fund markets itself as providing investment exposure to such instruments. The Investment Manager is registered with the CFTC as a CPO. However, with respect to the Fund, the Investment Manager has claimed an exclusion from registration as a CPO pursuant to CFTC Rule 4.5. For the Investment Manager to remain eligible for this exclusion, the Fund must comply with certain limitations, including limits on its ability to use any commodity interests and limits on the manner in which the Fund holds out its use of such commodity interests. These limitations may restrict the Fund’s ability to pursue its investment objectives and strategies, increase the costs of implementing its strategies, result in higher expenses for the Fund, and/or adversely affect the Fund’s total return. To the extent the Fund becomes ineligible for this exclusion from CFTC regulation, the Fund may consider steps in order to continue to qualify for exemption from CFTC regulation, or may determine to operate subject to CFTC regulation.

Regulatory Risk — LIBOR

Certain instruments in which the Fund may invest have relied or continue in some fashion upon the London Interbank Offered Rate (“LIBOR”). LIBOR was traditionally an average interest rate, determined by the ICE Benchmark Administration, that banks charge one another for the use of short-term money. On March 5, 2021, the Financial Conduct Authority (“FCA”), the United Kingdom’s financial regulatory body and regulator of LIBOR, publicly announced that all U.S. Dollar LIBOR settings will either cease to be provided by any administrator or will no longer be representative (i) immediately after December 31, 2021 for one-week and two-month U.S. Dollar LIBOR settings and (ii) immediately after June 30, 2023 for the remaining U.S. Dollar LIBOR settings. As of January 1, 2022, as a result of supervisory guidance from U.S. regulators, U.S. regulated entities have generally ceased entering into new LIBOR contracts with limited exceptions. Publication of all Japanese yen and the one- and six-month sterling LIBOR settings have ceased, and while publication of the three-month Sterling LIBOR setting will continue through at least the end of March 2024 on the basis of a changed methodology (known as “synthetic LIBOR”), this rate has been designated by the FCA as unrepresentative of the underlying market that it seeks to

measure and is solely available for use in legacy transactions. Certain bank-sponsored committees in other jurisdictions, including Europe, the United Kingdom, Japan and Switzerland, have selected alternative reference rates denominated in other currencies. Although the transition process away from LIBOR for many instruments has been completed, some LIBOR use is continuing and there are potential effects related to the transition away from LIBOR or continued use of LIBOR on the Fund, or on certain instruments in which the Fund invests, which can be difficult to ascertain, and may vary depending on factors that include, but are not limited to: (i) existing fallback or termination provisions in individual contracts and (ii) whether, how, and when industry participants adopt new reference rates for affected instruments. So-called “tough legacy” contracts have LIBOR interest rate provisions with no fallback provisions contemplating a permanent discontinuation of LIBOR, inadequate fallback provisions or fallback provisions which may not effectively result in a transition away from LIBOR prior to LIBOR’s planned replacement date. On March 15, 2022, the Adjustable Interest Rate (LIBOR) Act was signed into law. This law provides a statutory fallback mechanism on a nationwide basis to replace LIBOR with a benchmark rate that is selected by the Board of Governors of the Federal Reserve System based on the Secured Overnight Financing Rate (“SOFR”) for tough legacy contracts. On February 27, 2023, the Federal Reserve System’s final rule in connection with this law became effective, establishing benchmark replacements based on SOFR and Term SOFR (a forward-looking measurement of market expectations of SOFR implied from certain derivatives markets) for applicable tough legacy contracts governed by U.S. law. In addition, the FCA has announced that it will require the publication of synthetic LIBOR for the one-month, three-month and six-month U.S. Dollar LIBOR settings after June 30, 2023 through at least September 30, 2024. Certain of the Fund’s investments may involve individual tough legacy contracts which may be subject to the Adjustable Interest Rate (LIBOR) Act or synthetic LIBOR and no assurances can be given that these measures will have had the intended effects. Moreover, certain aspects of the transition from LIBOR have relied or will continue to rely on the actions of third-party market participants, such as clearing houses, trustees, administrative agents, asset servicers and certain service providers; PIMCO cannot guarantee the performance of such market participants and any failure on the part of such market participants to manage their part of the LIBOR transition could impact the Fund. The transition of investments from LIBOR to a replacement rate as a result of amendment, application of existing fallbacks, statutory requirements or otherwise may also result in a reduction in the value of certain instruments held by the Fund or a reduction in the effectiveness of related Fund transactions such as hedges. In addition, an instrument’s transition to a replacement rate could result in variations in the reported yields of the Fund that holds such instrument. Any such

180 PIMCO CLOSED-END FUNDS

(Unaudited)

effects of the transition away from LIBOR, as well as other unforeseen effects, could result in losses to the Fund.

Reinvestment Risk

Income from the Fund’s portfolio will decline if and when the Fund invests the proceeds from matured, traded or called debt obligations at market interest rates that are below the portfolio’s current earnings rate. For instance, during periods of declining interest rates, an issuer of debt obligations may exercise an option to redeem securities prior to maturity, forcing the Fund to invest in lower-yielding securities. The Fund also may choose to sell higher yielding portfolio securities and to purchase lower yielding securities to achieve greater portfolio diversification, because the portfolio managers believe the current holdings are overvalued or for other investment-related reasons. A decline in income received by the Fund from its investments is likely to have a negative effect on dividend levels and the market price, NAV and/or overall return of the Common Shares.

REIT Risk

REITs are pooled investment vehicles that own, and usually operate, income-producing real estate. Some REITs also finance real estate. If a REIT meets certain requirements, including distributing to shareholders substantially all of its taxable income (other than net capital gains), then it is not typically taxed on the income distributed to shareholders. Therefore, REITs may pay higher dividends than other issuers.

REITs can be divided into three basic types: Equity REITs, Mortgage REITs and Hybrid REITs. Equity REITs invest the majority of their assets directly in real property. They derive their income primarily from rents received and any profits on the sale of their properties. Mortgage REITs invest the majority of their assets in real estate mortgages and derive most of their income from mortgage interest payments. As its name suggests, Hybrid REITs combine characteristics of both Equity REITs and Mortgage REITs.

An investment in a REIT, or in a real estate linked derivative instrument linked to the value of a REIT, is subject to the risks that impact the value of the underlying properties of the REIT. These risks include loss to casualty or condemnation, and changes in supply and demand, interest rates, zoning laws, regulatory limitations on rents, property taxes and operating expenses. Other factors that may adversely affect REITs include poor performance by management of the REIT, changes to the tax laws, or failure by the REIT to qualify for favorable tax treatment. The securities of REITs involve greater risks than those associated with larger, more established companies and may be subject to more abrupt or erratic price movements because of interest rate changes, economic conditions and other factors. For example, the value of these securities may decline when interest rates rise and will also be affected by the real estate market and by the

management or development of the underlying properties. The underlying properties may be subject to mortgage loans, which may also be subject to the risks of default. REITs are also subject to default by borrowers and self-liquidation, and are heavily dependent on cash flow. Some REITs lack diversification because they invest in a limited number of properties, a narrow geographic area, or a single type of property. Mortgage REITs may be impacted by the quality of the credit extended.

Repurchase Agreements Risk

The Fund may enter into repurchase agreements, in which the Fund purchases a security from a bank or broker-dealer, which agrees to repurchase the security at the Fund’s cost plus interest within a specified time. If the party agreeing to repurchase should default, the Fund would seek to sell the securities which it holds. This could involve procedural costs or delays in addition to a loss on the securities if their value should fall below their repurchase price. Repurchase agreements may be or become illiquid. These events could also trigger adverse tax consequences for the Fund.

Risk Retention Investment Risk

The Fund may invest in risk retention tranches of commercial mortgage-backed securities (“CMBS”) or other eligible securitizations, if any (“risk retention tranches”), which are eligible residual interests held by the sponsors of such securitizations pursuant to the final rules implementing the credit risk retention requirements of Section 941 of the Dodd-Frank Act (the “U.S. Risk Retention Rules”). In the case of CMBS transactions, for example, the U.S. Risk Retention Rules permit all or a portion of the retained credit risk associated with certain securitizations (i.e., retained risk) to be held by an unaffiliated “third party purchaser,” such as the Fund, if, among other requirements, the third-party purchaser holds its retained interest, unhedged, for at least five years following the closing of the CMBS transaction, after which it is entitled to transfer its interest in the securitization to another person that meets the requirements for a third-party purchaser. Even after the required holding period has expired, due to the generally illiquid nature of such investments, no assurance can be given as to what, if any, exit strategies will ultimately be available for any given position.

In addition, there is limited guidance on the application of the final U.S. Risk Retention Rules to specific securitization structures. There can be no assurance that the applicable federal agencies charged with the implementation of the final U.S. Risk Retention Rules (the Federal Deposit Insurance Corporation, the Comptroller of the Currency, the Federal Reserve Board, the SEC, the Department of Housing and Urban Development, and the Federal Housing Finance Agency) could not take positions in the future that differ from the interpretation of such rules taken or embodied in such securitizations, or that the final U.S. Risk Retention Rules will not change.

ANNUAL REPORT | JUNE 30, 2023 181

Principal Risks of the Funds (Cont.)

Furthermore, in situations where the Fund invests in risk retention tranches of securitizations structured by third parties, the Fund may be required to execute one or more letters or other agreements, the exact form and nature of which will vary (each, a “Risk Retention Agreement”) under which it will make certain undertakings designed to ensure such securitization complies with the U.S. Risk Retention Rules. Such Risk Retention Agreements may include a variety of representations, warranties, covenants and other indemnities, each of which may run to various transaction parties. If the Fund breaches any undertakings in any Risk Retention Agreement, it will be exposed to claims by the other parties thereto, including for any losses incurred as a result of such breach, which could be significant and exceed the value of the Fund’s investments.

Securities Lending Risk

For the purpose of achieving income, the Fund may lend its portfolio securities to brokers, dealers, and other financial institutions provided a number of conditions are satisfied, including that the loan is fully collateralized. When the Fund lends portfolio securities, its investment performance will continue to reflect changes in the value of the securities loaned, and the Fund will also receive a fee or interest on the collateral. Securities lending involves the risk of loss of rights in the collateral or delay in recovery of the collateral if the borrower fails to return the security loaned or becomes insolvent. The Fund may pay lending fees to a party arranging the loan. Cash collateral received by the Fund in securities lending transactions may be invested in short-term liquid fixed income instruments or in money market or short-term mutual funds, or similar investment vehicles, including affiliated money market or short-term mutual funds. The Fund bears the risk of such investments.

Senior Debt Risk

The Fund may be subject to greater levels of credit risk than funds that do not invest in below investment grade senior debt. The Fund may also be subject to greater levels of liquidity risk than funds that do not invest in senior debt. Restrictions on transfers in loan agreements, a lack of publicly available information and other factors may, in certain instances, make senior debt more difficult to sell at an advantageous time or price than other types of securities or instruments. Additionally, if the issuer of senior debt prepays, the Fund will have to consider reinvesting the proceeds in other senior debt or similar instruments that may pay lower interest rates.

Short Exposure Risk

The Fund’s short sales and short positions, if any, are subject to special risks. A short sale involves the sale by the Fund of a security that it does not own with the hope of purchasing the same security at a later date at a lower price. The Fund may also enter into a short position through a forward commitment or a short derivative position

through a futures contract or swap agreement. If the price of the security or derivative has increased during this time, then the Fund will incur a loss equal to the increase in price from the time that the short sale was entered into plus any transaction costs (i.e., premiums and interest) paid to the broker-dealer to borrow securities. Therefore, short sales involve the risk that losses may be exaggerated, potentially losing more money than the actual cost of the investment. By contrast, a loss on a long position arises from decreases in the value of the security and is limited by the fact that a security’s value cannot decrease below zero.

By investing the proceeds received from selling securities short, the Fund could be deemed to be employing a form of leverage, which creates special risks. The use of leverage may increase the Fund’s exposure to long security positions and make any change in the Fund’s NAV greater than it would be without the use of leverage. This could result in increased volatility of returns. There is no guarantee that any leveraging strategy the Fund employs will be successful during any period in which it is employed.

In times of unusual or adverse market, economic, regulatory or political conditions, the Fund may not be able, fully or partially, to implement its short selling strategy. Periods of unusual or adverse market, economic, regulatory or political conditions generally may exist for long periods of time. Also, there is the risk that the third party to the short sale or short position will not fulfill its contractual obligations, causing a loss to the Fund.

Special Purpose Acquisition Companies (“SPACs”) Risk

The Fund may invest in securities of SPACs or similar special purpose entities that pool funds to seek potential acquisition opportunities. Unless and until an acquisition is completed, a SPAC generally invests its assets (less a portion retained to cover expenses) in US government securities, money market securities or holds cash; if an acquisition that meets the requirements for the SPAC is not completed within a pre-established period of time, the invested funds are returned to the entity’s shareholders unless shareholders approve alternative options. Because SPACs and similar entities are in essence blank check companies without operating history or ongoing business other than seeking acquisitions, the value of their securities is particularly dependent on the ability of the entity’s management to identify and complete a profitable acquisition. A SPAC’s structure may result in significant dilution of a stockholder’s share value immediately upon the completion of a business combination due to, among other reasons, interests held by the SPAC sponsor, conversion of warrants into additional shares, shares issued in connection with a business combination and/or certain embedded costs. There is no guarantee that the SPACs in which the Fund invests will complete an acquisition or that any acquisitions that are completed will be profitable. Some

182 PIMCO CLOSED-END FUNDS

(Unaudited)

SPACs may pursue acquisitions only within certain industries or regions, which may increase the volatility of their prices. In addition, these securities, which are typically traded in the over-the-counter market, may be considered illiquid and/or be subject to restrictions on resale.

Smaller Company Risk

The general risks associated with debt instruments or equity securities are particularly pronounced for securities issued by companies with small market capitalizations. Small capitalization companies involve certain special risks. They are more likely than larger companies to have limited product lines, markets or financial resources, or to depend on a small, inexperienced management group. Securities of smaller companies may trade less frequently and in lesser volume than more widely held securities and their values may fluctuate more sharply than other securities. They may also have limited liquidity. These securities may therefore be more vulnerable to adverse developments than securities of larger companies, and the Fund may have difficulty purchasing or selling securities positions in smaller companies at prevailing market prices. Also, there may be less publicly available information about smaller companies or less market interest in their securities as compared to larger companies. Companies with medium-sized market capitalizations may have risks similar to those of smaller companies.

Sovereign Debt Risk

In addition to the other risks applicable to debt investments, sovereign debt may decline in value as a result of default or other adverse credit event resulting from an issuer’s inability or unwillingness to make principal or interest payments in a timely fashion. A sovereign entity’s failure to make timely payments on its debt can result from many factors, including, without limitation, insufficient foreign (non-U.S.) currency reserves or an inability to sufficiently manage fluctuations in relative currency valuations, an inability or unwillingness to satisfy the demands of creditors and/or relevant supranational entities regarding debt service or economic reforms, the size of the debt burden relative to economic output and tax revenues, cash flow difficulties, and other political and social considerations. The risk of loss to the Fund in the event of a sovereign debt default or other adverse credit event is heightened by the unlikelihood of any formal recourse or means to enforce its rights as a holder of the sovereign debt. In addition, sovereign debt restructurings, which may be shaped by entities and factors beyond the Fund’s control, may result in a loss in value of the Fund’s sovereign debt holdings.

Structured Investments Risk

Holders of structured products, including structured notes, credit-linked notes and other types of structured products, bear the risks of the underlying investments, index or reference obligation and are

subject to counterparty risk. The Fund may have the right to receive payments only from the structured product, and generally does not have direct rights against the issuer or the entity that sold the assets to be securitized. While certain structured products enable the investor to acquire interests in a pool of securities without the brokerage and other expenses associated with directly holding the same securities, investors in structured products generally pay their share of the structured product’s administrative and other expenses. Although it is difficult to predict whether the prices of indices and securities underlying structured products will rise or fall, these prices (and, therefore, the prices of structured products) are generally influenced by the same types of political and economic events that affect issuers of securities and capital markets generally. If the issuer of a structured product uses shorter term financing to purchase longer term securities, the issuer may be forced to sell its securities at below market prices if it experiences difficulty in obtaining such financing, which may adversely affect the value of the structured products owned by the Fund. Structured products generally entail risks associated with derivative instruments.

Subprime Risk

Loans, and debt instruments collateralized by loans (including Alt Lending ABS), acquired by the Fund may be subprime in quality, or may become subprime in quality. Although there is no specific legal or market definition of “subprime,” subprime loans are generally understood to refer to loans made to borrowers that display poor credit histories and other characteristics that correlate with a higher default risk. Accordingly, subprime loans, and debt instruments secured by such loans (including Alt Lending ABS), have speculative characteristics and are subject to heightened risks, including the risk of nonpayment of interest or repayment of principal, and the risks associated with investments in high yield securities. In addition, these instruments could be subject to increased regulatory scrutiny. The Fund is not restricted by any particular borrower credit risk criteria and/or qualifications when acquiring loans or debt instruments collateralized by loans.

Subsidiary Risk

To the extent the Fund invests through one or more of its subsidiaries, the Fund would be exposed to the risks associated with such subsidiary’s investments. Such subsidiaries would likely not be registered as investment companies under the 1940 Act and therefore would not be subject to all of the investor protections of the 1940 Act. Changes in the laws of the United States and/or the jurisdiction in which a subsidiary is organized could result in the inability of the Fund and/or the subsidiary to operate as intended and could adversely affect the Fund.

ANNUAL REPORT | JUNE 30, 2023 183

Principal Risks of the Funds (Cont.)

Synthetic Convertible Securities Risk

Synthetic convertible securities involve the combination of separate securities that possess the two principal characteristics of a traditional convertible security (i.e., an income-producing component and a right to acquire an equity security). Synthetic convertible securities are often achieved, in part, through investments in warrants or options to buy common stock (or options on a stock index), and therefore are subject to the risks associated with derivatives. The value of a synthetic convertible security will respond differently to market fluctuations than a traditional convertible security because a synthetic convertible is composed of two or more separate securities or instruments, each with its own market value. Because the convertible component is typically achieved by investing in warrants or options to buy common stock at a certain exercise price, or options on a stock index, synthetic convertible securities are subject to the risks associated with derivatives. In addition, if the value of the underlying common stock or the level of the index involved in the convertible component falls below the exercise price of the warrant or option, the warrant or option may lose all value.

Tax Risk

The Fund has elected to be treated as a “regulated investment company” (a “RIC”) under the Code and intends each year to qualify and be eligible to be treated as such, so that it generally will not be subject to U.S. federal income tax on its net investment income or net short-term or long-term capital gains, that are distributed (or deemed distributed, as described below) to shareholders. In order to qualify and be eligible for such treatment, the Fund must meet certain asset diversification tests, derive at least 90% of its gross income for such year from certain types of qualifying income, and distribute to its shareholders at least 90% of its “investment company taxable income” as that term is defined in the Code (which includes, among other things, dividends, taxable interest and the excess of any net short-term capital gains over net long-term capital losses, as reduced by certain deductible expenses).

The Fund’s investment strategy will potentially be limited by its intention to continue qualifying for treatment as a RIC, and can limit the Fund’s ability to continue qualifying as such. The tax treatment of certain of the Fund’s investments under one or more of the qualification or distribution tests applicable to regulated investment companies is uncertain. An adverse determination or future guidance by the IRS or a change in law might affect the Fund’s ability to qualify or be eligible for treatment as a RIC. Income and gains from certain of a Fund’s activities may not constitute qualifying income to a RIC for purposes of the 90% gross income test. If a Fund were to treat income or gain from a particular investment or activity as qualifying income and the income or gain were later determined not to constitute qualifying income and, together with any other nonqualifying income,

caused the Fund’s nonqualifying income to exceed 10% of its gross income in any taxable year, the Fund would fail to qualify as a RIC unless it is eligible to and does pay a tax at the Fund level.

If, in any year, the Fund were to fail to qualify for treatment as a RIC under the Code and were ineligible to or did not otherwise cure such failure, the Fund would be subject to tax on its taxable income at corporate rates and, when such income is distributed, shareholders would be subject to further tax on such distributions to the extent of the Fund’s current or accumulated earnings and profits.

U.S. Government Securities Risk

Certain U.S. Government Securities such as U.S. Treasury bills, notes and bonds and mortgage-related securities guaranteed by the GNMA, are supported by the full faith and credit of the United States; others, such as those of Federal Home Loan Banks (“FHLBs”) or the Federal Home Loan Mortgage Corporation (“FHLMC”), are supported by the right of the issuer to borrow from the U.S. Treasury; others, such as those of the FNMA, are supported by the discretionary authority of the U.S. Government to purchase the agency’s obligations; and still others are supported only by the credit of the agency, instrumentality or corporation. U.S. government securities are subject to market risk, interest rate risk and credit risk. Although legislation has been enacted to support certain government sponsored entities, including the FHLBs, FHLMC and FNMA, there is no assurance that the obligations of such entities will be satisfied in full, or that such obligations will not decrease in value or default. It is difficult, if not impossible, to predict the future political, regulatory or economic changes that could impact the government sponsored entities and the values of their related securities or obligations. In addition, certain governmental entities, including FNMA and FHLMC, have been subject to regulatory scrutiny regarding their accounting policies and practices and other concerns that may result in legislation, changes in regulatory oversight and/or other consequences that could adversely affect the credit quality, availability or investment character of securities issued by these entities. Yields available from U.S. Government debt securities are generally lower than the yields available from such other securities. The values of U.S. Government Securities change as interest rates fluctuate.

Periodically, uncertainty regarding the status of negotiations in the U.S. government to increase the statutory debt ceiling could increase the risk that the U.S. government may default on payments on certain U.S. government securities, cause the credit rating of the U.S. government to be downgraded, increase volatility in the stock and bond markets, result in higher interest rates, reduce prices of U.S. Treasury and other securities, and/or increase the costs of various kinds of debt. If a government-sponsored entity is negatively impacted by legislative or regulatory action (or lack thereof), is unable to meet

184 PIMCO CLOSED-END FUNDS

(Unaudited)

its obligations, or its creditworthiness declines, the performance of a fund that holds securities of the entity will be adversely impacted.

Valuation Risk

Certain securities in which the Fund invests may be less liquid and more difficult to value than other types of securities. Investments for which market quotations are not readily available are valued at fair value as determined in good faith pursuant to Rule 2a-5 under the 1940 Act. Fair value pricing may require subjective determinations about the value of a security or other asset. As a result, there can be no assurance that fair value pricing will result in adjustments to the prices of securities or other assets or that fair value pricing will reflect actual market value, and it is possible that the fair value determined for a security or other asset will be materially different from quoted or published prices, from the prices used by others for the same security or other asset and/or from the value that actually could be or is realized upon the sale of that security or other asset.

Zero-Coupon Bond, Step-Ups and Payment-In-Kind Securities Risk

The market prices of zero-coupon, step-ups and payment-in-kind securities are generally more volatile than the prices of securities that pay interest periodically and in cash and are likely to respond to changes in interest rates to a greater degree than other types of debt securities with similar maturities and credit quality. Because zero-coupon securities bear no interest, their prices are especially volatile. And because zero-coupon bondholders do not receive interest payments, the prices of zero-coupon securities generally fall more dramatically than those of bonds that pay interest on a current basis when interest rates rise. The market for zero-coupon and payment-in-kind securities may suffer decreased liquidity. In addition, as these securities may not pay cash interest, the Fund’s investment exposure to these securities and their risks, including credit risk, will increase during the time these securities are held in the Fund’s portfolio. Further, to maintain its qualification for treatment as a RIC and to avoid Fund-level U.S. federal income and/or excise taxes, the Fund is required to distribute to its shareholders any income it is deemed to have received in respect of such investments, notwithstanding that cash has not been received currently, and the value of paid-in-kind interest. Consequently, the Fund may have to dispose of portfolio securities under disadvantageous circumstances to generate the cash or may have to leverage itself by borrowing the cash to satisfy this distribution requirement. The required distributions, if any, would result in an increase in the Fund’s exposure to these securities. Zero coupon bonds, step-ups and payment-in-kind securities allow an issuer to avoid or delay the need to generate cash to meet current interest payments and, as a result, may involve greater credit risk than bonds that pay interest currently or in cash. The Fund would be required to distribute the income on these instruments as it

accrues, even though the Fund will not receive the income on a current basis or in cash. Thus, the Fund may sell other investments, including when it may not be advisable to do so, to make income distributions to its shareholders.

Use of Derivatives

A Fund may use derivative instruments for other purposes, including to seek to increase liquidity, provide efficient portfolio management, broaden investment opportunities (including taking short or negative positions), implement a tax or cash management strategy, gain exposure to a particular security or segment of the market, modify the effective duration of the Fund’s portfolio investments and/or enhance total return.

ANNUAL REPORT | JUNE 30, 2023 185

Risk Management Strategies1 (Unaudited)

A Fund may (but is not required to) use various investment strategies to attempt to hedge exposure to reduce the risk of price fluctuations of its portfolio securities, the risk of loss, and to preserve capital. Derivatives strategies and instruments that a Fund may use include, among others, reverse repurchase agreements; interest rate swaps; total return swaps; credit default swaps; basis swaps; other types of swap agreements or options thereon; dollar rolls; futures and forward contracts (including foreign currency exchange contracts); short sales; options on financial futures; options based on either an index of municipal securities or taxable debt securities whose prices, PIMCO believes, correlate with the prices of the Fund’s investments; other derivative transactions; loans of portfolio securities and when-issued, delayed delivery and forward commitment transactions. Income earned by a Fund from its hedging and related transactions may be subject to one or more special U.S. federal income tax rules that can affect the amount, timing and/or character of distributions to holders of the Fund’s Common Shares. For instance, many hedging activities will be treated as capital gain and, if not offset by net realized capital loss, will be distributed to shareholders in taxable distributions. If effectively used, hedging strategies will offset in varying percentages losses incurred on a Fund’s investments due to adverse interest rate changes. There is no assurance that these hedging strategies will be available at any time or that PIMCO will determine to use them for a Fund or, if used, that the strategies will be successful. PIMCO may determine not to engage in hedging strategies or to do so only in unusual circumstances or market conditions. In addition, a Fund may be subject to certain restrictions on its use of hedging strategies imposed by guidelines of one or more ratings agencies that may issue ratings on any preferred shares issued by the Fund.

A Fund may take certain actions if short-term interest rates increase or market conditions otherwise change (or the Fund anticipates such an increase or change) and the Fund’s leverage begins (or is expected) to adversely affect holders of its Common Shares. In order to attempt to offset such a negative impact of leverage on holders of Common Shares, a Fund may shorten the average maturity or duration of its investment portfolio (by investing in short-term, high quality securities or implementing certain hedging strategies). Should a Fund issue preferred shares, the Fund also may attempt to reduce leverage by redeeming or otherwise purchasing preferred shares or by reducing any holdings in other instruments that create leverage. The success of any such attempt to limit leverage risk depends on PIMCO’s ability to accurately predict interest rate or other market changes. Because of the difficulty of making such predictions, a Fund may not be successful in managing its interest rate exposure in the manner described above.

In addition, each Fund has adopted certain investment limitations designed to limit investment risk. See “Fundamental Investment Restrictions” below for a description of these limitations.

Effects of Leverage1 (Unaudited)

The following table is furnished in response to requirements of the SEC. It is designed to illustrate the effects of leverage through the use of senior securities, as that term is defined under Section 18 of the 1940 Act, on Common Share total return, assuming investment portfolio total returns (consisting of income and changes in the value of investments held in a Fund’s portfolio) of -10%, -5%, 0%, 5% and 10%. The table below reflects each Fund’s continued use of reverse repurchase agreements as of June 30, 2023 as a percentage of total managed assets (including assets attributable to such leverage), the estimated annual effective interest expense rate payable by the Fund on such instruments (based on market conditions as of June 30, 2023, and the annual return that the Fund’s portfolio must experience (net of expenses) in order to cover such costs of the reverse repurchase agreements based on such estimated annual effective interest expense rate. The information below does not reflect any Fund’s use of certain other forms of economic leverage achieved through the use of other

instruments or transactions not considered to be senior securities under the 1940 Act, such as covered credit default swaps or other derivative instruments.

The assumed investment portfolio returns in the table below are hypothetical figures and are not necessarily indicative of the investment portfolio returns experienced or expected to be experienced by the Fund. Your actual returns may be greater or less than those appearing below. In addition, actual borrowing expenses associated with reverse repurchase agreements (or dollar rolls or borrowings, if any) used by the Fund may vary frequently and may be significantly higher or lower than the rate used for the example below.

The information below does not reflect a Fund’s use of certain other forms of economic leverage achieved through the use of other instruments or transactions not considered to be senior securities under the 1940 Act, such as total return swaps or other derivative instruments.

Common Share total return is composed of two elements — the distributions paid by a Fund to holders of Common Shares (the amount of which is largely determined by the net investment income of the Fund after paying dividend payments on Preferred Shares and expenses on any forms of leverage outstanding) and gains or losses on the value of the securities and other instruments the Fund owns. As required by SEC rules, the table assumes that a Fund is more likely to suffer capital losses than to enjoy capital appreciation. For example, to assume a portfolio total return of 0%, a Fund must assume that the income it receives on its investments is entirely offset by losses in the value of those investments. This table reflects hypothetical performance of a Fund’s portfolio and not the actual performance of the Fund’s Common Shares, the value of which is determined by market forces and other factors.

Should a Fund elect to add additional leverage to its portfolio, any benefits of such additional leverage cannot be fully achieved until the proceeds resulting from the use of such leverage have been received by the Fund and invested in accordance with the Fund’s investment objectives and policies. As noted above, a Fund’s willingness to use additional leverage, and the extent to which leverage is used at any time, will depend on many factors, including, among other things, PIMCO’s assessment of the yield curve environment, interest rate trends, market conditions and other factors.

Other Information Regarding Investment Restrictions

From time to time, a Fund may voluntarily participate in actions (for example, rights offerings, conversion privileges, exchange offers, credit event settlements, etc.) where the issuer or counterparty offers securities or instruments to holders or counterparties, such as the Fund, and the acquisition is determined to be beneficial to Fund shareholders (“Voluntary Action”). Notwithstanding any percentage investment limitation listed under this “Investment Restrictions” section or any percentage investment limitation of the 1940 Act or rules thereunder, if a Fund has the opportunity to acquire a permitted security or instrument through a Voluntary Action, and the Fund will exceed a percentage investment limitation following the acquisition, it will not constitute a violation if, prior to the receipt of the securities or instruments and after announcement of the offering, the Fund sells an offsetting amount of assets that are subject to the investment limitation in question at a price at least equal to the value of the securities or instruments to be acquired.

Unless otherwise indicated, all percentage limitations on Fund investments (as stated herein) that are not: (i) specifically included in this “Investment Restrictions” section; or (ii) imposed by the 1940 Act, rules thereunder, the Code or related regulations (the “Elective Investment Restrictions”), will apply only at the time of investment unless the acquisition is a Voluntary Action. The percentage limitations and absolute prohibitions with respect to Elective Investment Restrictions are not applicable to the Fund’s acquisition of securities or instruments through a Voluntary Action.

A Fund may engage in roll-timing strategies where the Fund seeks to extend the expiration or maturity of a position, such as a forward contract, futures contract or to-be-announced (“TBA”) transaction, on an underlying asset by closing out the position before expiration and contemporaneously opening a new position with respect to the same underlying asset that has substantially similar terms except for a later expiration date. Such “rolls” enable the Fund to maintain continuous investment exposure to an underlying asset beyond the expiration of

190 PIMCO CLOSED-END FUNDS

(Unaudited)

the initial position without delivery of the underlying asset. Similarly, as certain standardized swap agreements transition from OTC trading to mandatory exchange-trading and clearing due to the implementation of Dodd-Frank Act regulatory requirements, the Fund may “roll” an existing OTC swap agreement by closing out the position before expiration and contemporaneously entering into a new exchange-traded and cleared swap agreement on the same underlying asset with substantially similar terms except for a later expiration date. These types of new positions opened contemporaneous with the closing of an existing position on the same underlying asset with substantially similar terms are collectively referred to as “Roll Transactions.” Elective Investment Restrictions (defined in the preceding paragraph), which normally apply at the time of investment, do not apply to Roll Transactions (although Elective Investment Restrictions will apply to the Fund’s entry into the initial position). In addition and notwithstanding the foregoing, for purposes of this policy, those Non-Fundamental Investment Restrictions that are considered Elective Investment Restrictions for purposes of the policy on Voluntary Actions (described in the preceding paragraph) are also Elective Investment Restrictions for purposes of this policy on Roll Transactions. The Fund will test for compliance with Elective Investment Restrictions at the time of the Fund’s initial entry into a position, but the percentage limitations and absolute prohibitions set forth in the Elective Investment Restrictions are not applicable to the Fund’s subsequent acquisition of securities or instruments through a Roll Transaction.

194 PIMCO CLOSED-END FUNDS

Approval of Investment Management Agreements (Unaudited)

PTY, PCN, PHK, PFL, PFN

The Investment Company Act of 1940, as amended (the “1940 Act”), requires that the Board of Trustees (the “Board” or the “Trustees”), including a majority of the Trustees who are not “interested persons,” as that term is defined in the 1940 Act (the “Independent Trustees”), of each of PIMCO Corporate & Income Opportunity Fund (“PTY”), PIMCO Corporate & Income Strategy Fund (“PCN”), PIMCO High Income Fund (“PHK”), PIMCO Income Strategy Fund (“PFL”), and PIMCO Income Strategy Fund II (“PFN”) (each, a “Fund” and, collectively, the “Funds”), voting separately, annually approve the continuation of the Investment Management Agreement between each Fund and Pacific Investment Management Company LLC (“PIMCO”) (each, an “Agreement” and, collectively, the “Agreements”). At an in-person meeting held on June 14, 2023 (the “Approval Meeting”), the Board, including the Independent Trustees, considered and unanimously approved the continuation of each Agreement for an additional one-year period commencing on August 1, 2023.

In addition to the Approval Meeting, the Contracts Committee (the “Committee”) and the Performance Committee of the Board held a joint meeting on May 19, 2023 to discuss materials provided by PIMCO in connection with the Trustees’ review of the Agreements. The annual contract review process also involved multiple discussions and meetings with members of the Committee and the full Committee (the Approval Meeting, together with such discussions and meetings, the “Contract Renewal Meetings”). Throughout the process, the Independent Trustees received legal advice from independent legal counsel that is experienced in 1940 Act matters and independent of PIMCO (“Independent Counsel”), and with whom they met separately from PIMCO during the Contract Renewal Meetings. Representatives from PIMCO attended portions of the Contract Renewal Meetings and responded to questions from the Independent Trustees. The Committee also received and reviewed a memorandum from Independent Counsel regarding the Trustees’ responsibilities in considering each Agreement and the fees paid thereunder.

In connection with their deliberations regarding the proposed continuation of the Agreements, the Board, including the Independent Trustees, considered such information and factors as they believed, in light of the legal advice furnished to them and their own business judgment, to reasonably be necessary to evaluate the terms of the Agreements. The Trustees also considered the nature, quality and extent of the various investment management, administrative and other services performed by PIMCO under the Agreements.

In evaluating each Agreement, the Board, including the Independent Trustees, reviewed extensive materials provided by PIMCO in response to questions, inclusive of follow-up inquiries, submitted by the Independent Trustees and Independent Counsel. The Board also met

with senior representatives of PIMCO regarding its personnel, operations, and estimated profitability as they relate to the Funds. The Trustees also considered the broad range of information relevant to the annual contract review that is provided to the Board (including its various standing committees) at meetings throughout the year, including reports on investment performance based on net asset value (“NAV”), market value (both absolute and compared against its Broadridge Performance Universe (as defined below)) and distribution yield, use of leverage (if applicable), information regarding share price premiums and/or discounts, risks, and other portfolio information, including any use of derivatives, as well as periodic reports on, among other matters, pricing and valuation, quality and cost of portfolio trade execution, compliance, and shareholder and other services provided by PIMCO and its affiliates. To assist with their review, the Trustees reviewed summaries prepared by PIMCO that analyzed each Fund based on a number of factors, including fees/expenses, performance, distribution yield, and risk-based factors, as of December 31, 2022. They also considered, among other information, performance based on NAV and market value, investment objective and strategy, portfolio managers, assets under management, outstanding leverage, share price premium and/or discount information, annual fund operating expenses, total expense ratio and management fee comparisons between each Fund and its Broadridge Expense Group (as defined below), and estimated profitability to PIMCO from its relationship with each Fund. In considering the Broadridge Performance Universe and Broadridge Expense Group (both as defined below), the Trustees requested that PIMCO comment on whether the peer funds selected for each Fund by Broadridge Financial Solutions, Inc. (“Broadridge”) provided an appropriate comparison, and if not, whether PIMCO believes another peer group would provide a more appropriate comparison.

The Trustees’ conclusions as to the continuation of each Agreement were based on a comprehensive consideration of all information provided to the Trustees during the Contract Renewal Meetings and throughout the year and were not the result of any single factor. Some of the factors that figured particularly in the Trustees’ deliberations are described below, although individual Trustees may have evaluated the information presented differently from one another, attributing different weights to various factors. The Trustees evaluated information available to them on a Fund-by-Fund basis, and their determinations were made separately in respect of each Fund.

Nature, Extent and Quality of Services

As part of their review, the Trustees received and considered descriptions of various functions performed by PIMCO for the Funds, such as portfolio management, compliance monitoring, portfolio trading practices, and oversight of third-party service providers. They also considered information regarding the overall organization and business functions of PIMCO, including, without limitation, information

ANNUAL REPORT | JUNE 30, 2023 195

Approval of Investment Management Agreements (Cont.)

regarding senior management, portfolio managers and other personnel providing investment management, administrative, and/or other services, and general corporate ownership and business operations unrelated to the Funds. The Trustees examined PIMCO’s abilities to provide high-quality investment management and other services to the Funds, noting PIMCO’s long history and experience in managing closed-end funds, such as the Funds, including experience monitoring discounts and premiums and complying with New York Stock Exchange (NYSE) requirements. Among other information, the Trustees considered the investment philosophy and research and decision-making processes of PIMCO; the experience of key advisory personnel of PIMCO responsible for portfolio management of the Funds; information regarding the Funds’ use of leverage; the ability of PIMCO to attract and retain capable personnel; the background and capabilities of the senior management and staff of PIMCO; the general process or philosophy for determining employee compensation; and the operational infrastructure, including technology and systems and cybersecurity measures, of PIMCO.

In addition, the Trustees noted the extensive range of services that PIMCO provides to the Funds beyond investment management services. In this regard, the Trustees reviewed the extent and quality of PIMCO’s services with respect to regulatory compliance and its ability to comply with the investment policies of the Funds; the compliance programs and risk controls of PIMCO (including the implementation of new policies and programs); the specific contractual obligations of PIMCO pursuant to the Agreements; the nature, extent, and quality of the supervisory and administrative services PIMCO is responsible for providing to the Funds; PIMCO’s risk management function; the time and resources PIMCO expends monitoring the leverage employed by the Funds, including the covenants and restrictions imposed by certain forms of leverage such as the Funds’ preferred shares; and conditions that might affect PIMCO’s ability to provide high-quality services to the Funds in the future under the Agreements, including, but not limited to, PIMCO’s financial condition and operational stability. The Trustees also took into account the entrepreneurial, business and other risks that PIMCO has undertaken as investment manager and sponsor of the Funds. Specifically, the Trustees considered that PIMCO’s responsibilities include continual management of investment, operational, enterprise, legal, regulatory, and compliance risks as they relate to the Funds. The Trustees also noted PIMCO’s activities under its contractual obligation to coordinate, oversee and supervise the Funds’ various outside service providers, including its negotiation of certain service providers’ fees and its due diligence and evaluation of service providers’ infrastructure, cybersecurity programs, compliance programs, and business continuity programs, among other matters. The Trustees also considered PIMCO’s ongoing development of its own infrastructure and information technology, including its proprietary software and applications, to support the Funds through, among other things, cybersecurity, business continuity planning, and risk management.

After their review and deliberations, the Trustees concluded that the nature, extent and quality of the overall services provided by PIMCO under each Agreement were appropriate.

Fee and Expense Information

In assessing the reasonableness of each Fund’s fees and expenses under its Agreement, the Trustees requested and considered, among other information, the Fund’s management fee and its total expenses as a percentage of average net assets attributable to common shares and as a percentage of average total managed assets (including assets attributable both to common shares and specified leverage outstanding), in comparison to the management fees and other expenses of a group of industry peer funds identified by Broadridge as pursuing investment strategies with classifications/objectives similar to the Fund (for each Fund, its “Broadridge Expense Group”) as well as of a broader universe of peer funds identified by Broadridge (for each Fund, its “Broadridge Expense Universe”). In each case, the total expense ratio information was provided both inclusive and exclusive of interest and borrowing expenses. The Fund-specific fee and expense results discussed below were prepared and provided by Broadridge and were not independently verified by the Trustees. The Trustees noted that only leveraged closed-end funds were considered for inclusion in the Broadridge Expense Groups and Broadridge Expense Universes.

The Trustees considered information regarding the investment performance and fees for other funds and accounts managed by PIMCO, if any, including funds and accounts with comparable investment programs and/or principal investment strategies to those of the Funds, as well as certain other funds requested by the Trustees with broadly similar strategies and/or investment types. The Trustees considered information provided by PIMCO indicating that, in comparison to certain other products managed by PIMCO, including any open-end funds and exchange-traded funds with broadly similar strategies and/or investment types, there are additional portfolio management challenges in managing closed-end funds such as the Funds. For example, the challenges associated with managing closed-end funds may include investing in non-traditional and less liquid holdings, a greater use of leverage, issues relating to trading on a national securities exchange and managing a fund’s dividend practices. In addition, the Independent Trustees considered information provided by PIMCO as to the generally broader and more extensive services provided to the Funds in comparison to those provided to private funds or institutional or separate accounts; the higher demands placed on PIMCO to provide considerable shareholder services due to the volume of investors; the greater entrepreneurial, enterprise, and reputational risk in managing registered closed-end funds; and the expenses, and impact on PIMCO, associated with the more extensive regulatory and compliance requirements to which the Funds are subject

196 PIMCO CLOSED-END FUNDS

(Unaudited)

in comparison to private funds or institutional or separate accounts. The Trustees were advised by PIMCO that, in light of these additional challenges and additional services, different pricing structures between closed-end funds and other products managed by PIMCO are to be expected, and that comparisons of pricing structures across these products may not always be apt comparisons, even where other products have comparable investment objectives and strategies to those of the Funds.

The Trustees also took into account that the Funds have preferred shares outstanding and use other forms of leverage, such as by the use of reverse repurchase agreements, which increases the amount of management fees payable by each Fund under its Agreement (because each Fund’s fees are calculated either based on net assets, including assets attributable to preferred shares outstanding, or based on total managed assets, including assets attributable to preferred shares and certain other forms of leverage outstanding). In this regard, the Trustees took into account that PIMCO has a financial incentive for the Funds to use or continue to use leverage on which management fees are charged, which may create a conflict of interest between PIMCO, on one hand, and the Funds’ common shareholders, on the other. Therefore, the Trustees noted that the total fees paid by each Fund to PIMCO under the Fund’s unified fee arrangement would therefore vary more with increases and decreases in leverage than under a non-unified fee arrangement, all other things being equal. The Trustees considered information provided by PIMCO and related presentations as to why each Fund’s use of leverage continues to be appropriate and in the best interests of the respective Fund under current market conditions. The Trustees noted that each quarter they receive information from PIMCO comparing the recent, historical and projected costs of each Fund’s existing leverage arrangements against other available financing options, as well as information relating to PIMCO’s views regarding economic or other risks of maintaining those leverage arrangements and/or replacing them with alternate forms of financing. The Trustees also considered PIMCO’s representation that it will use leverage for the Funds solely as it determines to be in the best interests of the Funds from an investment perspective and without regard to the level of compensation PIMCO receives.

The Trustees noted that, for each of PFL and PFN the contractual and actual management fee rates for the Fund under its unified fee arrangement were above the median contractual and actual management fees of the other funds in its Broadridge Expense Group, calculated both on average net assets and on average total managed assets. For each of PCN and PHK, the contractual management fee rate for the Fund under its unified fee arrangement was above the median contractual management fees of other funds in its Broadridge Expense Group, calculated both on average net assets and on average total managed assets, while the actual management fee rate for the Fund

under its unified fee arrangement was above the median actual management fees of the other funds in its Broadridge Expense Group calculated on average total managed assets and below the median actual management fees of the other funds in its Broadridge Expense Group calculated on average net assets. For PTY, the contractual management fee rate for the Fund under its unified fee arrangement was at the median contractual management fees of other funds in its Broadridge Expense Group, calculated both on average net assets and on average total managed assets, while the actual management fee rate for the Fund under its unified fee arrangement was at the median actual management fees of the other funds in its Broadridge Expense Group calculated on total managed assets and below the median actual management fees of the other funds in its Broadridge Expense Group calculated on average net assets. In this regard, the Trustees took into account that each Fund’s unified fee arrangement covers substantially all of the Fund’s operating fees and expenses (“Operating Expenses”), and therefore, all other things being equal, would tend to be higher than the contractual management fee rates of other funds in the Broadridge Expense Group, which generally do not have a unified fee structure and instead incur Operating Expenses directly and in addition to the management fee. The Trustees determined that a comparison of each Fund’s total expense ratio with the total expense ratios of its Broadridge Expense Group would generally provide more meaningful comparisons than comparing contractual and actual management fee rates in isolation.

In this regard, the Trustees noted PIMCO’s view that the unified fee arrangements have benefited and will continue to benefit common shareholders because they provide an expense structure (including Operating Expenses) that is essentially fixed for the duration of the contractual period as a percentage of either NAV, including daily net assets attributable to outstanding preferred shares of the Fund (as in the case of PTY, PCN, and PHK), or total managed assets, including any assets attributable to any outstanding preferred shares or other forms of leverage of the Fund minus accrued liabilities other than liabilities representing leverage (as in the case of PFL and PFN), as applicable, making it more predictable under ordinary circumstances in comparison to other fee and expense structures, under which the Funds’ Operating Expenses (including certain third-party fees and expenses) could vary significantly over time. The Trustees also considered that the unified fee arrangements generally insulate the Funds and common shareholders from increases in applicable third-party and certain other expenses because PIMCO, rather than the Funds, would bear the risk of such increases (though the Trustees also noted that PIMCO would benefit from any reductions in such expenses).

Performance Information

Fund-specific comparative performance results for the Funds reviewed by the Trustees are discussed below. With respect to investment performance, the Trustees considered information regarding each Fund’s performance based on NAV and market value, as applicable, net of the Fund’s fees and expenses, both on an absolute basis and relative to the performance of its Broadridge Performance Universe (as defined below). The Trustees requested information provided by Broadridge regarding the investment performance of a broad universe of funds within the same investment classification/category that Broadridge determined are comparable to those of each Fund (for each Fund, its “Broadridge Performance Universe”). The comparative performance information was prepared and provided by Broadridge and was not independently verified by the Trustees. The Trustees also considered information regarding the Funds’ comparative yields and risk-adjusted returns. The Trustees recognized that the performance data reflects a snapshot of a period as of a particular date and that selecting a different performance period could produce significantly different results. They further acknowledged that long-term performance could be impacted by even one period of significant outperformance or underperformance. The Trustees considered information from PIMCO regarding the risks undertaken by each Fund, including the use of leverage, and PIMCO’s management and oversight of the Fund’s risk profile, including in instances where the Fund outperformed its Broadridge Performance Universe. For those Funds that the Board identified as having underperformed their Performance Universe to an extent, or over a period of time, that the Board felt warranted additional inquiry, the Board discussed with PIMCO each such Fund’s performance, potential reasons for the relative performance, and, if necessary, steps that PIMCO had taken, or intended to take, to improve performance.

In addition, the Trustees considered matters bearing on the Funds and their advisory arrangements at their meetings throughout the year, including a review of performance data at each regular meeting (by both the Board and its Performance Committee).

Profitability, Economies of Scale, and Fall-out Benefits

The Trustees considered estimated profitability analyses provided by PIMCO, which included, among other information, (i) PIMCO’s estimated pre- and post-distribution operating margin for each Fund, as well as PIMCO’s aggregate estimated pre- and post-distribution operating margin from all of the closed-end funds advised by PIMCO, including the Funds (collectively, the “Estimated Margins”), in each case for the one-year period ended December 31, 2022; and (ii) where applicable, a year-over-year comparison of PIMCO’s Estimated Margins for the one-year periods ended December 31, 2022 and December 31, 2021. The Trustees also took into account explanations from PIMCO

regarding how certain of PIMCO’s corporate and shared expenses were allocated among the Funds and other funds and accounts managed by PIMCO for purposes of developing profitability estimates. Based on the profitability analyses provided by PIMCO, the Trustees determined, taking into account the various assumptions made, that such profitability did not appear to be excessive.

The Trustees also considered information regarding possible economies of scale in the operation of the Funds, including in connection with at-the-market offerings conducted by the Funds. The Trustees noted that the Funds do not currently have any breakpoints in their management fees. The Trustees considered that, as closed-end investment companies, the Funds do not continually offer new shares to raise additional assets (as does a typical open-end investment company), but may raise additional assets through follow-on offerings (including at-the-market offerings) and dividend reinvestments and may also experience asset growth through investment performance and/or the increased use of leverage. The Trustees noted PIMCO’s assertion that it may share the benefits of potential economies of scale, if any, with the Funds and their shareholders in a number of ways, including investing in portfolio and trade operations management, firm technology and cybersecurity measures, middle and back office support, legal and compliance, and fund administration logistics; senior management supervision and governance of those services; and the enhancement of services provided to the Funds in return for fees paid. The Trustees also considered that the unified fee arrangements provide inherent economies of scale because a Fund maintains competitive fixed unified fees even if the particular Fund’s assets decline and/or operating costs increase. The Trustees further considered that, in contrast, breakpoints may be used as a proxy for charging higher fees on lower asset levels and that when a fund’s assets decline, breakpoints may reverse, which causes expense ratios to increase. The Trustees also considered that, unlike the Funds’ unified fee arrangements, funds with “pass through” administrative fee

structures may experience increased expense ratios when fixed dollar fees are charged against declining fund assets. The Trustees also considered that the unified fee arrangements protect shareholders, during the contractual period, from a rise in operating costs that may result from, among other things, PIMCO’s investments in various business enhancements and infrastructure. The Trustees noted that PIMCO has made extensive investments in these areas.

Additionally, the Trustees considered so-called “fall-out benefits” to PIMCO, such as reputational value derived from serving as investment manager to the Funds and research, statistical and quotation services that PIMCO may receive from broker-dealers executing the Funds’ portfolio transactions on an agency basis.

198 PIMCO CLOSED-END FUNDS

(Unaudited)

Fund-by-Fund Analysis

With regard to the investment performance of each Fund and the fees charged to each Fund, the Board considered the following information. With respect to performance quintile rankings for a Fund compared to its Broadridge Performance Universe, the first quintile represents the highest (best) performance and the fifth quintile represents the lowest performance. The Board considered each Fund’s performance and fees in light of the limitations inherent in the methodology for determining such comparative groups.

PTY

With respect to the Fund’s common share total return performance (based on NAV) relative to its respective Broadridge Performance Universe, the Trustees noted that the Fund had third quintile performance for the one-year period, second quintile performance for the three-year period and first quintile performance for the five- and ten-year periods ended December 31, 2022.

The Trustees noted that the Fund’s total expense ratio (including interest and borrowing expenses) calculated on both average total managed assets and average net assets was below the median total expense ratio (including interest and borrowing expenses) of the funds in its Broadridge Expense Group and Broadridge Expense Universe. The Trustees noted that the Fund’s total expense ratio (excluding interest and borrowing expenses) calculated on both average total managed assets and average net assets was below the median total expense ratio (excluding interest and borrowing expenses) of the funds in its Broadridge Expense Group and Broadridge Expense Universe.

PCN

With respect to the Fund’s common share total return performance (based on NAV) relative to its respective Broadridge Performance Universe, the Trustees noted that the Fund had third quintile performance for the one- and three-year periods and second quintile performance for the five- and ten-year periods ended December 31, 2022.

The Trustees noted that the Fund’s total expense ratio (including interest and borrowing expenses) calculated on both average total managed assets and average net assets was below the median total expense ratio (including interest and borrowing expenses) of the funds in its Broadridge Expense Group and Broadridge Expense Universe.

Privacy Policy1 (Unaudited)

The Funds2,3 consider customer privacy to be a fundamental aspect of their relationships with shareholders and are committed to maintaining the confidentiality, integrity and security of their current, prospective and former shareholders’ non-public personal information. The Funds have developed policies that are designed to protect this confidentiality, while allowing shareholder needs to be served.

OBTAINING NON-PUBLIC PERSONAL INFORMATION

In the course of providing shareholders with products and services, the Funds and certain service providers to the Funds, such as the Funds’ investment advisers or sub-advisers (“Advisers”), may obtain non-public personal information about shareholders, which may come from sources such as account applications and other forms, from other written, electronic or verbal correspondence, from shareholder transactions, from a shareholder’s brokerage or financial advisory firm, financial professional or consultant, and/or from information captured on applicable websites.

RESPECTING YOUR PRIVACY

As a matter of policy, the Funds do not disclose any non-public personal information provided by shareholders or gathered by the Funds to non-affiliated third parties, except as required or permitted by law or as necessary for such third parties to perform their agreements with respect to the Funds. As is common in the industry, non-affiliated companies may from time to time be used to provide certain services, such as preparing and mailing prospectuses, reports, account statements and other information, conducting research on shareholder satisfaction and gathering shareholder proxies. The Funds or their affiliates may also retain non-affiliated companies to market Fund shares or products which use Fund shares and enter into joint marketing arrangements with them and other companies. These companies may have access to a shareholder’s personal and account information, but are permitted to use this information solely to provide the specific service or as otherwise permitted by law. In most cases, the shareholders will be clients of a third party, but the Funds may also provide a shareholder’s personal and account information to the shareholder’s respective brokerage or financial advisory firm and/or financial professional or consultant.

SHARING INFORMATION WITH THIRD PARTIES

The Funds reserve the right to disclose or report personal or account information to non-affiliated third parties in limited circumstances where the Funds believe in good faith that disclosure is required under law, to cooperate with regulators or law enforcement authorities, to protect their rights or property, or upon reasonable request by any Fund in which a shareholder has invested. In addition, the Funds may disclose information about a shareholder or a shareholder’s accounts to a non-affiliated third party at the shareholder’s request or with the consent of the shareholder.

SHARING INFORMATION WITH AFFILIATES

The Funds may share shareholder information with their affiliates in connection with servicing shareholders’ accounts, and subject to applicable law may provide shareholders with information about products and services that the Funds or their Advisers, distributors or their affiliates (“Service Affiliates”) believe may be of interest to such shareholders. The information that the Funds may share may include, for example, a shareholder’s participation in the Funds or in other investment programs sponsored by a Service Affiliate, a shareholder’s ownership of certain types of accounts (such as IRAs), information about the Funds’ experiences or transactions with a shareholder, information captured on applicable websites, or other data about a shareholder’s accounts, subject to applicable law. The Funds’ Service Affiliates, in turn, are not permitted to share shareholder information with non-affiliated entities, except as required or permitted by law.

PROCEDURES TO SAFEGUARD PRIVATE INFORMATION

The Funds take seriously the obligation to safeguard shareholder non-public personal information. In addition to this policy, the Funds have implemented procedures that are designed to restrict access to a shareholder’s non-public personal information to internal personnel who need to know that information to perform their jobs, such as servicing shareholder accounts or notifying shareholders of new products or services. Physical, electronic and procedural safeguards are in place to guard a shareholder’s non-public personal information.

INFORMATION COLLECTED FROM WEBSITES

The Funds or their service providers and partners may collect information from shareholders via websites they maintain. The information collected via websites maintained by the Funds or their service providers includes client non-public personal information.

CHANGES TO THE PRIVACY POLICY

From time to time, the Funds may update or revise this privacy policy. If there are changes to the terms of this privacy policy, documents containing the revised policy on the relevant website will be updated.

1 Amended as of June 25, 2020.

2 PIMCO Investments LLC (“PI”) serves as the Funds’ distributor and does not provide brokerage services or any financial advice to investors in the Funds solely because it distributes the Funds. This Privacy Policy applies to the activities of PI to the extent that PI regularly effects or engages in transactions with or for a shareholder of a series of a Trust who is the record owner of such shares. For purposes of this Privacy Policy, references to “the Funds” shall include PI when acting in this capacity.

3 When distributing this Policy, a Fund may combine the distribution with any similar distribution of its investment adviser’s privacy policy. The distributed, combined, policy may be written in the first person (i.e. by using “we” instead of “the Funds”).

(e) Pre-approval policies and procedures

(1) The Registrant’s Audit Oversight Committee has adopted pre-approval policies and procedures (the “Procedures”) to govern the Audit Oversight Committee’s pre-approval of (i) all audit services and permissible non-audit services to be provided to the Registrant by its independent accountant, and (ii) all permissible non-audit services to be provided by such independent accountant to the Registrant’s investment adviser and to any entity controlling, controlled by, or under common control with the investment adviser that provides ongoing services to the Registrant (collectively, the “Service Affiliates”) if the services provided directly relate to the Registrant’s operations and financial reporting. In accordance with the Procedures, the Audit Oversight Committee is responsible for the engagement of the independent accountant to certify the Registrant’s financial statements for each fiscal year. With respect to the pre-approval of non-audit services provided to the Registrant and its Service Affiliates, the Procedures provide that the Audit Oversight Committee may annually pre-approve a list of types or categories of non-audit services that may be provided to the Registrant or its Service Affiliates, or the Audit Oversight Committee may pre-approve such services on a project-by-project basis as they arise. Unless a type of service has received general pre-approval, it will require specific pre-approval by the Audit Oversight Committee if it is to be provided by the independent accountant. The Procedures also permit the Audit Oversight Committee to delegate authority to one or more of its members to pre-approve any proposed non-audit services that have not been previously pre-approved by the Audit Oversight Committee, subject to the ratification by the full Audit Oversight Committee no later than its next scheduled meeting.

(2) With respect to the services described in paragraphs (b) through (d) of this Item 4, no amount was approved by the Audit Oversight Committee pursuant to paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X.

(f) Not applicable.

(h) The Registrant’s Audit Oversight Committee has considered whether the provision of non-audit services that were rendered to the Registrant’s investment adviser, and any entity controlling, controlled by, or under common control with the investment adviser that provides ongoing services to the Registrant which were not pre-approved (not requiring pre-approval) is compatible with maintaining the principal accountant’s independence.

(i) Not applicable.

(j) Not applicable.

Item 6. Schedule of Investments.

The information required by this Item 6 is included as part of the annual report to shareholders filed under Item 1 of this Form N-CSR.

Item 7. Disclosure of Proxy Voting Policies and Procedures for Closed-End Management Investment Companies.

Policy Statement: The proxy voting policy is intended to foster PIMCO’s compliance with its fiduciary obligations and applicable law; the policy applies to any voting or consent rights with respect to securities held in accounts over which PIMCO has discretionary voting authority. The Policy is designed in a manner reasonably expected to ensure that voting and consent rights are exercised in the best interests of PIMCO’s clients.

Overview: PIMCO has adopted a written proxy voting¹ policy (“Proxy Policy”) as required by Rule 206(4)-6 under the Advisers Act. As a general matter, when PIMCO has proxy voting authority, PIMCO has a fiduciary obligation to monitor corporate events and to take appropriate action on client proxies that come to its attention. Each proxy is voted on a case-by-case basis, taking into account relevant facts and circumstances. When considering client proxies, PIMCO may determine not to vote a proxy in limited circumstances.

Equity Securities.² PIMCO has retained an Industry Service Provider (“ISP”) to provide research and voting recommendations for proxies relating to equity securities in accordance with the ISP’s guidelines. By following the guidelines of an independent third party, PIMCO seeks to mitigate potential conflicts of interest PIMCO may have with respect to proxies covered by the ISP. PIMCO will follow the recommendations of the ISP unless: (i) the ISP does not provide a voting recommendation; or (ii) a portfolio manager decides to override the ISP’s voting recommendation. In either such case as described above, the Legal and Compliance department will review the proxy to determine whether a material conflict of interest, or the appearance of one, exists.

Fixed Income Securities. Fixed income securities can be processed as proxy ballots or corporate action-consents⁴ at the discretion of the issuer/ custodian. When processed as proxy ballots, the ISP generally does not provide a voting recommendation and their role is limited to election processing and recordkeeping. When processed as corporate action-consents, the Legal and Compliance department will review all election forms to determine whether a conflict of interest, or the appearance of one, exists with respect to the PM’s consent election. PIMCO’s Credit Research and Portfolio Management Groups are responsible for issuing recommendations on how to vote proxy ballots and corporation action-consents with respect to fixed income securities.

Resolution of potential/identified conflicts of interest. The Proxy Policy permits PIMCO to seek to resolve material conflicts of interest by pursuing any one of several courses of action. With respect to material conflicts of interest between PIMCO and a client account, the Proxy Policy permits PIMCO to either: (i) convene a working group to assess and resolve the conflict (the “Proxy Working Group”); or (ii) vote in accordance with protocols previously established by the Proxy Policy, the Proxy Working Group and/or other relevant procedures approved by PIMCO’s Legal and Compliance department with respect to specific types of conflicts.

PIMCO will supervise and periodically review its proxy voting activities and the implementation of the Proxy Policy.

Sub-Adviser Engagement: As an investment manager, PIMCO may exercise its discretion to engage a Sub-Adviser to provide portfolio management services to the Fund. Consistent with its management responsibilities, the Sub-Adviser would assume the authority for voting proxies on behalf of PIMCO for the Fund. Sub-Advisers may utilize third parties to perform certain services related to their portfolio management responsibilities. As a fiduciary, PIMCO will maintain oversight of the investment management responsibilities (which may include proxy voting) performed by the Sub-Adviser and contracted third parties.

¹ Proxies generally describe corporate action consent rights (relative to fixed income securities) and proxy voting ballots (relative to fixed income or equity securities) as determined by the issuer or custodian.

² The term “Equity Securities” means common and preferred stock, including common and preferred shares issued by investment companies; it does not include debt securities convertible into equity securities.

³ Voting or consent rights shall not include matters which are primarily decisions to buy or sell investments, such as tender offers, exchange offers, conversions, put options, redemptions, and Dutch auctions.

Item 8. Portfolio Managers of Closed-End Management Investment Companies.

(a)(1)

As of August 31, 2023, the following individuals have primary responsibility for the day-to-day management of the PIMCO High Income Fund (the “Fund”):

Alfred T. Murata

Mr. Murata has been a portfolio manager of the Fund since September 2014. Mr. Murata is a managing director in the Newport Beach office and a portfolio manager on the mortgage credit team. Prior to joining PIMCO in 2001, he researched and implemented exotic equity and interest rate derivatives at Nikko Financial Technologies.

Mohit Mittal

Mr. Mittal has been a portfolio manager of the Fund since September 2014. Mr. Mittal is a managing director and portfolio manager in the Newport Beach office. He manages investment grade credit, total return and unconstrained bond portfolios and is a member of the Americas Portfolio Committee. Previously, he was a specialist on PIMCO’s interest rates and derivatives desk.

(a)(2)

The following summarizes information regarding each of the accounts, excluding the Fund, managed by the Portfolio Managers as of June 30, 2023, including accounts managed by a team, committee, or other group that includes a Portfolio Manager. Unless mentioned otherwise, the advisory fee charged for managing each of the accounts listed below is not based on performance.

	Registered Investment Companies		Other Pooled Investment Vehicles		Other Accounts
Portfolio Manager	#	AUM($million)	#	AUM($million)	#	AUM($million)
Alfred T. Murata1	21	$168,029.86	22	$45,379.20	5	$1,014.08
Mohit Mittal2	30	$97,287.67	26	$36,183.15	157	$87,612.71

¹Of these Other Pooled Investment Vehicles,   5     accounts totaling   $9,569.39       million in assets pay(s) an advisory fee that is based in part on the performance of the accounts.

²Of these Other Pooled Investment Vehicles,   4     accounts totaling   $4,908.28 million in assets pay(s) an advisory fee that is based in part on the performance of the accounts. Of these Other Accounts,   12     accounts totaling   $2,975.46     million in assets pay(s) an advisory fee that is based in part on the performance of the accounts.

From time to time, potential and actual conflicts of interest may arise between a portfolio manager’s management of the investments of the Fund, on the one hand, and the management of other accounts, on the other. Potential and actual conflicts of interest may also arise as a result of PIMCO’s other business activities and PIMCO’s possession of material non-public information (“MNPI”) about an issuer. Other accounts managed by a portfolio manager might have similar investment objectives or strategies as the Fund, track the same index the Fund tracks or otherwise hold, purchase, or sell securities that are eligible to be held, purchased or sold by the Fund. The other accounts might also have different investment objectives or strategies than the Fund. Investors should be aware that investments made by the Fund and the results achieved by the Fund at any given time are not expected to be the same as those made by other funds for which PIMCO acts as investment adviser, including funds with names, investment objectives and policies, and/or portfolio management teams, similar to the Fund. This may be attributable to a wide variety of factors, including, but not limited to, the use of a different strategy or portfolio management team, when a particular fund commenced operations or the size of a particular fund, in each case as compared to other similar funds. Potential and actual conflicts of interest may also arise as a result of PIMCO serving as investment adviser to accounts that invest in the Fund or to accounts in which the Fund invests. In this case, such conflicts of interest could in theory give rise to incentives for PIMCO to, among other things, vote proxies, purchase or redeem shares of the underlying account, or take other actions with respect to the underlying account, in a manner beneficial to the investing account and/or PIMCO but detrimental to the underlying account. Such conflicts of interest could similarly in theory give rise to incentives for PIMCO to, among other things, vote proxies or purchase or redeem shares of the underlying account, or take other actions with respect to the underlying account, in a manner beneficial to the underlying account and/or PIMCO and that may or may not be detrimental to the investing account. For example, even if there is a fee waiver or reimbursement in place relating to the Fund’s investment in an underlying account, or relating to an investing account’s investment in the Fund, this will not necessarily eliminate all conflicts of interest, as PIMCO could nevertheless have a financial incentive to favor

investments in PIMCO-affiliated funds and managers (for example, to increase the assets under management of PIMCO or a fund, product or line of business, or otherwise provide support to, certain funds, products or lines of business), which could also impact the manner in which certain transaction fees are set. Conversely, PIMCO’s duties to the Fund, as well as regulatory or other limitations applicable to the Fund, may affect the courses of action available to PIMCO-advised accounts (including the Fund) that invest in the Fund in a manner that is detrimental to such investing accounts. In addition, regulatory restrictions, actual or potential conflicts of interest or other considerations may cause PIMCO to restrict or prohibit participation in certain investments.

Because PIMCO is affiliated with Allianz SE, a large multi-national financial institution (together with its affiliates, “Allianz”), conflicts similar to those described below may occur between the Fund or other accounts managed by PIMCO and PIMCO’s affiliates or accounts managed by those affiliates. Those affiliates (or their clients), which generally operate autonomously from PIMCO, may take actions that are adverse to the Fund or other accounts managed by PIMCO. In many cases, PIMCO will not be in a position to mitigate those actions or address those conflicts, which could adversely affect the performance of the Fund or other accounts managed by PIMCO (each, a “Client,” and collectively, the “Clients”). In addition, because certain Clients are affiliates of PIMCO or have investors who are affiliates or employees of PIMCO, PIMCO may have incentives to resolve conflicts of interest in favor of these Clients over other Clients.

Knowledge and Timing of Fund Trades. A potential conflict of interest may arise as a result of a portfolio manager’s day-to-day management of the Fund. Because of their positions with the Fund, the portfolio managers know the size, timing and possible market impact of the Fund’s trades. It is theoretically possible that the portfolio managers could use this information to the advantage of other accounts they manage and to the possible detriment of the Fund.

Cross Trades. A potential conflict of interest may arise in instances where the Fund buys an instrument from a Client or sells an instrument to a Client (each, a “cross trade”). Such conflicts of interest may arise, among other reasons, as a result of PIMCO representing the interests of both the buying party and the selling party in the cross trade or because the price at which the instrument is bought or sold through a cross trade may not be as favorable as the price that might have been obtained had the trade been executed in the open market. PIMCO effects cross trades when appropriate pursuant to procedures adopted under applicable rules and SEC guidance. Among other things, such procedures require that the cross trade is consistent with the respective investment policies and investment restrictions of both parties and is in the best interests of both the buying and selling accounts.

Investment Opportunities. A potential conflict of interest may arise as a result of a portfolio manager’s management of a number of accounts with varying investment guidelines. Often, an investment opportunity may be suitable for one or more Clients, but may not be available in sufficient quantities for all accounts to participate fully. PIMCO has adopted policies and procedures reasonably designed to allocate investment opportunities on a fair and equitable basis over time. In addition, regulatory issues applicable to PIMCO or one or more Clients may result in certain Clients not receiving securities that may otherwise be appropriate for them.

PIMCO seeks to allocate orders across eligible Client accounts with similar investment guidelines and investment styles fairly and equitably, taking into consideration relevant factors including, among others, applicable investment restrictions and guidelines, including regulatory restrictions; Client account-specific investment objectives, restrictions and other Client instructions, as applicable; risk tolerances; amounts of available cash; the need to rebalance a Client account’s portfolio (e.g., due to investor contributions and redemptions); whether the allocation would result in a Client account receiving a trivial amount or an amount below the established minimum quantity; regulatory requirements; the origin of the investment; the bases for an issuer’s allocation to PIMCO; and other Client account-specific factors. As part of PIMCO’s trade allocation process, portions of new fixed income investment opportunities are distributed among Client account categories where the relevant portfolio managers seek to participate in the investment. Those portions are then further allocated among the Client accounts within such categories pursuant to PIMCO’s trade allocation policy. Portfolio managers managing quantitative strategies and specialized accounts, such as those focused on international securities, mortgage-backed securities, bank loans, or other specialized asset classes, will likely receive an increased distribution of new fixed income investment opportunities where the investment involves a quantitative strategy or specialized asset class that matches the investment objective or focus of the Client account category. PIMCO seeks to allocate fixed income investments to Client accounts with the general purpose of maintaining consistent concentrations across similar accounts and achieving, as nearly as possible, portfolio characteristic parity among such accounts. Client accounts furthest from achieving portfolio characteristic parity typically receive priority in allocations. With respect to an order to buy or sell an equity security in the secondary market, PIMCO seeks to allocate the order across Client accounts with similar investment guidelines and investment styles fairly and equitably over time, taking into consideration the relevant factors discussed above.

Any particular allocation decision among Client accounts may be more or less advantageous to any one Client or group of Clients, and certain allocations will, to the extent consistent with PIMCO’s fiduciary obligations, deviate from a pro rata basis among Clients in order to address for example, differences in legal, tax, regulatory, risk management, concentration, exposure, Client guideline limitations and/or mandate or strategy considerations for the relevant Clients. PIMCO may determine that an investment opportunity or particular purchases or sales are appropriate for one or more Clients, but not appropriate for other Clients, or are appropriate or suitable for, or available to, Clients but in different sizes, terms, or timing than is appropriate or suitable for other Clients. For example, some Clients have higher risk tolerances than other Clients, such as private funds, which, in turn, allows PIMCO to allocate a wider variety and/or greater percentage of certain types of investments (which may or may not outperform other types of investments) to such Clients. Further, the respective risk tolerances of different types of Clients may change over time as market conditions change. Those Clients receiving an increased allocation as a result of the effect of their respective risk tolerance may be Clients that pay higher investment management fees or that pay incentive fees. In addition, certain Client account categories focusing on certain types of investments or asset classes will be given priority in new issue distribution and allocation with respect to the investments or asset classes that are the focus of their investment mandate. PIMCO may also take into account the bases for an issuer’s allocation to PIMCO, for example, by giving priority allocations to Client accounts holding existing positions in the issuer’s debt if the issuer’s allocation to PIMCO is based on such holdings. Legal, contractual, or regulatory issues and/or related expenses applicable to PIMCO or one or more Clients may result in certain Clients not receiving securities that may otherwise be appropriate for them or may result in PIMCO selling securities out of Client accounts even if it might otherwise be beneficial to continue to hold them. Additional factors that are taken into account in the distribution and allocation of investment opportunities to Client accounts include, without limitation: ability to utilize leverage and risk tolerance of the Client account; the amount of discretion and trade authority given to PIMCO by the Client; availability of other similar investment opportunities; the Client account’s investment horizon and objectives; hedging, cash and liquidity needs of the portfolio; minimum increments and lot sizes; and underlying benchmark factors. Given all of the foregoing factors, the amount, timing, structuring, or terms of an investment by a Client, including the Fund, may differ from, and performance may be lower than, investments and performance of other Clients, including those that may provide greater fees or other compensation (including performance-based fees or allocations) to PIMCO. PIMCO has also adopted additional procedures to complement the general trade allocation policy that are designed to address potential conflicts of interest due to the side-by-side management of the Fund and certain pooled investment vehicles, including investment opportunity allocation issues.

From time to time, PIMCO may take an investment position or action for one or more Clients that may be different from, or inconsistent with, an action or position taken for one or more other Clients having similar or differing investment objectives. These positions and actions may adversely impact, or in some instances may benefit, one or more affected Clients (including Clients that are PIMCO affiliates) in which PIMCO has an interest, or which pays PIMCO higher fees or a performance fee. For example, a Client may buy a security and another Client may establish a short position in that same security. The subsequent short sale may result in a decrease in the price of the security that the other Client holds. Similarly, transactions or investments by one or more Clients may have the effect of diluting or otherwise disadvantaging the values, prices or investment strategies of another Client.

When PIMCO implements for one Client a portfolio decision or strategy ahead of, or contemporaneously with, similar portfolio decisions or strategies of another Client, market impact, liquidity constraints or other factors could result in one or more Clients receiving less favorable trading results, the costs of implementing such portfolio decisions or strategies could be increased or such Clients could otherwise be disadvantaged. On the other hand, potential conflicts may also arise because portfolio decisions regarding a Client may benefit other Clients. For example, the sale of a long position or establishment of a short position for a Client may decrease the price of the same security sold short by (and therefore benefit) other Clients, and the purchase of a security or covering of a short position in a security for a Client may increase the price of the same security held by (and therefore benefit) other Clients.

Under certain circumstances, a Client may invest in a transaction in which one or more other Clients are expected to participate, or already have made or will seek to make, an investment. In addition, to the extent permitted by applicable law, a Client may also engage in investment transactions that may result in other Clients being relieved of obligations, or that may cause other Clients to divest certain investments (e.g., a Client may make a loan to, or directly or indirectly acquire securities or indebtedness of, a company that uses the proceeds to refinance or reorganize its capital structure, which could result in repayment of debt held by another Client). Such Clients (or groups of Clients) may have conflicting interests and objectives in connection with such investments, including with respect to views on the operations or activities of the issuer involved, the targeted returns from the investment and the timeframe for, and method of, exiting the investment. When making such investments, PIMCO may do so in a way that favors one Client over another Client, even if both Clients are investing in the same security at the same time. Certain Clients may invest on a “parallel” basis (i.e., proportionately in all transactions at substantially the same time and on substantially the same terms and conditions). In addition, other accounts may expect to

invest in many of the same types of investments as another account. However, there may be investments in which one or more of such accounts does not invest (or invests on different terms or on a non-pro rata basis) due to factors such as legal, tax, regulatory, business, contractual or other similar considerations or due to the provisions of a Client’s governing documents. Decisions as to the allocation of investment opportunities among such Clients present numerous conflicts of interest, which may not be resolved in a manner that is favorable to a Client’s interests. To the extent an investment is not allocated pro rata among such entities, a Client could incur a disproportionate amount of income or loss related to such investment relative to such other Client.

In addition, Clients may invest alongside one another in the same underlying investments or otherwise pursuant to a substantially similar investment strategy as one or more other Clients. In such cases, certain Clients may have preferential liquidity and information rights relative to other Clients holding the same investments, with the result that such Clients will be able to withdraw/redeem their interests in underlying investments in priority to Clients who may have more limited access to information or more restrictive withdrawal/redemption rights. Clients with more limited information rights or more restrictive liquidity may therefore be adversely affected in the event of a downturn in the markets.

Further, potential conflicts may be inherent in PIMCO’s use of multiple strategies. For example, conflicts will arise in cases where different Clients invest in different parts of an issuer’s capital structure, including circumstances in which one or more Clients may own private securities or obligations of an issuer and other Clients may own or seek to acquire private securities of the same issuer. For example, a Client may acquire a loan, loan participation or a loan assignment of a particular borrower in which one or more other Clients have an equity investment, or may invest in senior debt obligations of an issuer for one Client and junior debt obligations or equity of the same issuer for another Client. PIMCO may also, for example, direct a Client to invest in a tranche of a structured finance vehicle, such as a CLO or CDO, where PIMCO is also, at the same or different time, directing another Client to make investments in a different tranche of the same vehicle, which tranche’s interests may be adverse to other tranches.

PIMCO may also cause a Client to purchase from, or sell assets to, an entity, such as a structured finance vehicle, in which other Clients may have an interest, potentially in a manner that will have an adverse effect on the other Clients. There may also be conflicts where, for example, a Client holds certain debt or equity securities of an issuer, and that same issuer has issued other debt, equity or other instruments that are owned by other Clients or by an entity, such as a structured finance vehicle, in which other Clients have an interest.

In each of the situations described above, PIMCO may take actions with respect to the assets held by one Client that are adverse to the other Clients, for example, by foreclosing on loans, by putting an issuer into default, or by exercising rights to purchase or sell to an issuer, causing an issuer to take actions adverse to certain classes of securities, or otherwise. In negotiating the terms and conditions of any such investments, or any subsequent amendments or waivers or taking any other actions, PIMCO may find that the interests of a Client and the interests of one or more other Clients could conflict. In these situations, decisions over items such as whether to make the investment or take an action, proxy voting, corporate reorganization, how to exit an investment, or bankruptcy or similar matters (including, for example, whether to trigger an event of default or the terms of any workout) may result in conflicts of interest. Similarly, if an issuer in which a Client and one or more other Clients directly or indirectly hold different classes of securities (or other assets, instruments or obligations issued by such issuer or underlying investments of such issuer) encounters financial problems, decisions over the terms of any workout will raise conflicts of interests (including, for example, conflicts over proposed waivers and amendments to debt covenants). For example, a debt holder may be better served by a liquidation of the issuer in which it may be paid in full, whereas an equity or junior bond holder might prefer a reorganization that holds the potential to create value for the equity holders. In some cases PIMCO may refrain from taking certain actions or making certain investments on behalf of Clients in order to avoid or mitigate certain conflicts of interest or to prevent adverse regulatory or other effects on PIMCO, or may sell investments for certain Clients (in each case potentially disadvantaging the Clients on whose behalf the actions are not taken, investments not made, or investments sold). In other cases, PIMCO may not refrain from taking actions or making investments on behalf of certain Clients that have the potential to disadvantage other Clients. In addition, PIMCO may take actions or refrain from taking actions in order to mitigate legal risks to PIMCO or its affiliates or its Clients even if disadvantageous to a Client’s account. Moreover, a Client may invest in a transaction in which one or more other Clients are expected to participate, or already have made or will seek to make, an investment.

Additionally, certain conflicts may exist with respect to portfolio managers who make investment decisions on behalf of several different types of Clients. Such portfolio managers may have an incentive to allocate trades, time or resources to certain Clients, including those Clients who pay higher investment management fees or that pay incentive fees or allocations, over other Clients. These conflicts may be heightened with respect to portfolio managers who are eligible to receive a performance allocation under certain circumstances as part of their compensation.

From time to time, PIMCO personnel may come into possession of MNPI which, if disclosed, might affect an investor’s decision to buy, sell or hold a security. Should a PIMCO employee come into possession of MNPI with respect to an issuer, he or she generally will be prohibited from communicating such information to, or using such information for the benefit of, Clients, which could limit the ability of Clients to buy, sell or hold certain investments, thereby limiting the investment opportunities or exit strategies available to Clients. In addition, holdings in the securities or other instruments of an issuer by PIMCO or its affiliates may affect the ability of a Client to make certain acquisitions of or enter into certain transactions with such issuer. PIMCO has no obligation or responsibility to disclose such information to, or use such information for the benefit of, any person (including Clients).

PIMCO maintains one or more restricted lists of companies whose securities are subject to certain trading prohibitions due to PIMCO’s business activities. PIMCO may restrict trading in an issuer’s securities if the issuer is on a restricted list or if PIMCO has MNPI about that issuer. In some situations, PIMCO may restrict Clients from trading in a particular issuer’s securities in order to allow PIMCO to receive MNPI on behalf of other Clients. A Client may be unable to buy or sell certain securities until the restriction is lifted, which could disadvantage the Client. PIMCO may also be restricted from making (or divesting of) investments in respect of some Clients but not others. In some cases PIMCO may not initiate or recommend certain types of transactions, or may otherwise restrict or limit its advice relating to certain securities if a security is restricted due to MNPI or if PIMCO is seeking to limit receipt of MNPI.

PIMCO may conduct litigation or engage in other legal actions on behalf of one or more Clients. In such cases, Clients may be required to bear certain fees, costs, expenses and liabilities associated with the litigation. Other Clients that are or were investors in, or otherwise involved with, the subject investments may or may not (depending on the circumstances) be parties to such litigation actions, with the result that certain Clients may participate in litigation actions in which not all Clients with similar investments may participate, and such nonparticipating Clients may benefit from the results of such litigation actions without bearing or otherwise being subject to the associated fees, costs, expenses and liabilities. PIMCO, for example, typically does not pursue legal claims on behalf of its separate accounts. Furthermore, in certain situations, litigation or other legal actions pursued by PIMCO on behalf of a Client may be brought against or be otherwise adverse to a portfolio company or other investment held by a Client.

Co-Investments. The 1940 Act imposes significant limits on co-investment with affiliates of the Fund. PIMCO has received exemptive relief from the SEC that permits the Fund to, among other things, co-invest with certain affiliates. Co-investment transactions may give rise to conflicts of interest or perceived conflicts of interest among the Fund and its affiliates. If granted, the exemptive order will impose certain conditions that may limit or restrict the Fund’s ability to participate in an investment or participate in an investment to a lesser extent. An inability to receive the desired allocation to potential investments may affect the Fund’s ability to achieve the desired investment returns. In the event investment opportunities are allocated among the Fund and its affiliates pursuant to co-investment exemptive relief, the Fund may not be able to structure its investment portfolio in the manner desired. Although PIMCO will endeavor to allocate investment opportunities in a fair and equitable manner, the Fund will generally not be permitted to co-invest in any issuer in which a fund managed by PIMCO or any of its downstream affiliates (other than the Fund and its downstream affiliates) currently has an investment. However, the Fund would be able to co-invest with funds managed by PIMCO or any of its downstream affiliates, subject to compliance with existing regulatory guidance, applicable regulations and its allocation procedures. Pursuant to co-investment exemptive relief, the Fund will be able to invest in opportunities in which PIMCO and/or its affiliates has an investment, and PIMCO and/or its affiliates will be able to invest in opportunities in which the Fund has made an investment. From time to time, the Fund and its affiliates may make investments at different levels of an issuer’s capital structure or otherwise in different classes of an issuer’s securities. Such investments inherently give rise to conflicts of interest or perceived conflicts of interest between or among the various classes of securities that may be held by such entities. PIMCO has adopted procedures governing the co-investment in securities acquired in private placements with certain clients of PIMCO.

The foregoing is not a complete list of conflicts to which PIMCO or Clients may be subject. PIMCO seeks to review conflicts on a case-by-case basis as they arise. Any review will take into consideration the interests of the relevant Clients, the circumstances giving rise to the conflict, applicable PIMCO policies and procedures, and applicable laws. Clients (and investors in the Fund) should be aware that conflicts will not necessarily be resolved in favor of their interests and may in fact be resolved in a manner adverse to their interests. PIMCO will attempt to resolve such matters fairly, but even so, matters may be resolved in favor of other Clients which pay PIMCO higher fees or performance fees or in which PIMCO or its affiliates have a significant proprietary interest. There can be no assurance that any actual or potential conflicts of interest will not result in a particular Client or group of Clients receiving less favorable investment terms in or returns from certain investments than if such conflicts of interest did not exist.

Conflicts like those described above may also occur between Clients, on the one hand, and PIMCO or its affiliates, on the other. These conflicts will not always be resolved in favor of the Client. In addition, because PIMCO is affiliated with Allianz, a large multi-national financial institution, conflicts similar to those described above may occur between clients of PIMCO and PIMCO’s affiliates or accounts managed by those affiliates. Those affiliates (or their clients), which generally operate autonomously from PIMCO, may take actions that are adverse to PIMCO’s Clients. In many cases, PIMCO will have limited or no ability to mitigate those actions or address those conflicts, which could adversely affect Client performance. In addition, certain regulatory or internal restrictions may prohibit PIMCO from using certain brokers or investing in certain companies (even if such companies are not affiliated with Allianz) because of the applicability of certain laws and regulations or internal Allianz policies applicable to PIMCO, Allianz SE or their affiliates. An account’s willingness to negotiate terms or take actions with respect to an investment may also be, directly or indirectly, constrained or otherwise impacted to the extent Allianz SE, PIMCO, and/or their affiliates, directors, partners, managers, members, officers or personnel are also invested therein or otherwise have a connection to the subject investment (e.g., serving as a trustee or board member thereof).

Certain service providers to the Fund are expected to be owned by or otherwise related to or affiliated with a Client, and in certain cases, such service providers are expected to be, or are owned by, employed by, or otherwise related to, PIMCO, Allianz SE, their affiliates and/or their respective employees, consultants and other personnel. PIMCO may, in its sole discretion, determine to provide, or engage or recommend an affiliate of PIMCO to provide, certain services to the Fund, instead of engaging or recommending one or more third parties to provide such services. Subject to the governance requirements of a particular fund and applicable law, PIMCO or its affiliates, as applicable, will receive compensation in connection with the provision of such services. As a result, PIMCO faces a conflict of interest when selecting or recommending service providers for the Fund. Fees paid to an affiliated service provider will be determined in PIMCO’s commercially reasonable discretion, taking into account the relevant facts and circumstances, and consistent with PIMCO’s responsibilities. Although PIMCO has adopted various policies and procedures intended to mitigate or otherwise manage conflicts of interest with respect to affiliated service providers, there can be no guarantee that such policies and procedures (which may be modified or terminated at any time in PIMCO’s sole discretion) will be successful.

Performance Fees. A portfolio manager may advise certain accounts with respect to which the advisory fee is based entirely or partially on performance. Performance fee arrangements may create a conflict of interest for the portfolio manager in that the portfolio manager may have an incentive to allocate the investment opportunities that he or she believes might be the most profitable to such other accounts instead of allocating them to the Fund. PIMCO has adopted policies and procedures reasonably designed to allocate investment opportunities between the Fund and such other accounts on a fair and equitable basis over time.

As of June 30, 2023, the following explains the compensation structure of the individuals who have primary responsibility for day-to-day portfolio management of the Fund:

Portfolio Manager Compensation

PIMCO and its affiliates’ approach to compensation seeks to provide professionals with a compensation process that is driven by values of collaboration, openness, responsibility and excellence.

Generally, compensation packages consist of three components. The compensation program for portfolio managers is designed to align with clients’ interests, emphasizing each portfolio manager’s ability to generate long-term investment success for clients, among other factors. A portfolio manager’s compensation is not based solely on the performance of the Fund or any other account managed by that portfolio manager:

Base Salary – Base salary is determined based on core job responsibilities, positions/levels and market factors. Base salary levels are reviewed annually, when there is a significant change in job responsibilities or position, or when there is a significant change in market levels.

Variable Compensation – In addition to a base salary, portfolio managers have a variable component of their compensation, which is based on a combination of individual and company performance and includes both qualitative and quantitative factors. The following non-exhaustive list of qualitative and quantitative factors is considered when determining total compensation for portfolio managers:

•           Performance measured over a variety of longer- and shorter-term periods, including 5-year, 4-year, 3-year, 2-year and 1-year dollar-weighted and account-weighted, pre-tax total and risk-adjusted investment performance as judged against the applicable benchmarks (which may include internal investment performance-related benchmarks) for each account managed by a portfolio manager (including the Fund) and relative to applicable industry peer groups; and

•           Amount and nature of assets managed by the portfolio manager.

The variable compensation component of an employee’s compensation may include a deferred component. The deferred portion will generally be subject to vesting and may appreciate or depreciate based on the performance of PIMCO and/or its affiliates. PIMCO’s Long-Term Incentive Plan provides participants with deferred cash awards that appreciate or depreciate based on PIMCO’s operating earnings over a rolling three-year period.

Portfolio managers who are Managing Directors of PIMCO receive compensation from a non-qualified profit sharing plan consisting of a portion of PIMCO’s net profits. Portfolio managers who are Managing Directors receive an amount determined by the Compensation Committee, based upon an individual’s overall contribution to the firm.

I.         Covered Officers/Purpose of the Code

This Code of Ethics (this “Code”) pursuant to Section 406 of the Sarbanes-Oxley Act of 2002 has been adopted by the Funds and, except as provided in Section VI below, applies to each Fund’s Principal Executive Officer, Principal Financial Officer and Principal Accounting Officer (the “Covered Persons”). Each Covered Person is identified in Exhibit A.)

This Code has been adopted for the purpose of promoting:

• honest and ethical conduct, including the ethical handling of actual or apparent conflicts of interest between personal and professional relationships;

• full, fair, accurate, timely and understandable disclosure in reports and documents that a Fund files with, or submits to, the Securities and Exchange Commission (“SEC”) and in other public communications made by a Fund;

• compliance with applicable laws and governmental rules and regulations;

• the prompt internal reporting of violations of the Code to an appropriate person or persons identified in the Code; and

• accountability for adherence to the Code.

Each Covered Person should adhere to a high standard of business ethics and should be sensitive to situations that may give rise to conflicts of interest or the appearance thereof.

¹          The listed entities which are open-end investment companies are known as the “Trusts,” the listed entities which are publicly-traded closed-end investment companies are known as the “Closed-End Funds,” the listed entities which are closed-end investment companies operating as “interval” funds pursuant to Rule 23c-3 under the 1940 Act are known as the “Interval Funds”, and the listed entities which are business development companies are known as the “BDCs.” The Trusts’ respective series, the Closed-End Funds, the Interval Funds and the BDC are referred to herein as the “Funds.” References to “Trustees” include Directors, as applicable.

Sarbanes-Oxley Code of Ethics

II.         Covered Persons Should Handle Ethically Any Actual or Apparent Conflicts of Interest

Overview. A “conflict of interest” occurs when a Covered Person’s private interest interferes with the interests of, or his service to, the relevant Fund. For example, a conflict of interest would arise if a Covered Person, or a member of the Covered Person’s family, receives improper personal benefits as a result of the Covered Person’s position with the relevant Fund.

Certain conflicts of interest arise out of the relationships between Covered Persons and the relevant Fund and already are subject to conflict of interest provisions and procedures in the Investment Company Act of 1940, as amended (including the regulations thereunder, the “1940 Act”) and the Investment Advisers Act of 1940, as amended (including the regulations thereunder, the “Investment Advisers Act”) and other applicable laws. Indeed, conflicts of interest are endemic for registered management investment companies and those conflicts are both substantially and procedurally dealt with under the 1940 Act. For example, Covered Persons may not engage in certain transactions with a Fund because of their status as “affiliated persons” of such Fund. The compliance program of each Fund and the compliance programs of its investment adviser, principal underwriter (with respect to the Trusts) and administrator (each a “PIMCO-Affiliated Service Provider” and, collectively, the “PIMCO-Affiliated Service Providers”²) are reasonably designed to prevent, or identify and correct, violations of many of those provisions, although they are not designed to provide absolute assurance as to those matters. This Code does not, and is not intended to, repeat or replace these programs and procedures, and such conflicts fall outside of the parameters of this Code. See also Section V of this Code.

Although typically not presenting an opportunity for improper personal benefit, conflicts arise from, or as a result of, the contractual relationship between a Fund and its applicable PIMCO-Affiliated Service Providers of which the Covered Persons are also officers or employees. As a result, this Code recognizes that the Covered Persons will, in the normal course of their duties (whether for the Funds or for a PIMCO-Affiliated Service Provider, or for both), be involved in establishing policies and implementing decisions that will have different effects on the PIMCO- Affiliated Service Providers and the Funds. The participation of the Covered Persons in such activities is inherent in the contractual relationships between the Funds and their applicable PIMCO-Affiliated Service Providers and is consistent with the performance by the Covered Persons of their duties as officers of the relevant Fund. Thus, if performed in conformity with the provisions of the 1940 Act, the Investment Advisers Act, other applicable law and the relevant Fund’s constitutional documents, such activities will be deemed to have been handled ethically. Frequently, the 1940 Act establishes, as a mechanism for dealing with conflicts, requirements that such potential conflicts be disclosed to and approved by the Trustees of a Fund who are not “interested persons” of such Fund under the 1940 Act. In addition, it is recognized by each Fund’s Board of Trustees that the Covered Persons may also be officers or employees of one or more other investment companies covered by this or other codes and that such service, by itself, does not give rise to a conflict of interest.

²          Each PIMCO-Affiliated Service Provider is identified in Exhibit B.

Sarbanes-Oxley Code of Ethics

Other conflicts of interest are covered by the Code, even if such conflicts of interest are not the subject of provisions of the 1940 Act and the Investment Advisers Act. The following list provides examples of conflicts of interest under the Code, but Covered Persons should bear in mind that these examples are not exhaustive. The overarching principle is that the personal interest of a Covered Person should not be placed improperly before the interest of the relevant Fund, unless the personal interest is disclosed to and reviewed by other officers of such Fund or such Fund’s Chief Compliance Officer (“CCO”).

*        *        *         *

Each Covered Person must not:

• use his personal influence or personal relationships to improperly influence investment decisions or financial reporting by the relevant Fund whereby the Covered Person would benefit personally to the detriment of such Fund;

• cause the relevant Fund to take action, or fail to take action, for the individual personal benefit of the Covered Person rather than the benefit of such Fund; or

• retaliate against any other Covered Person or any employee of the Funds or their PIMCO-Affiliated Service Providers for reports of potential violations that are made in good faith.

There are some conflict of interest situations that should always be submitted for review by the President of the relevant Fund (or, with respect to activities of the President, by the Chairman of the relevant Fund or, if the same person holds the titles of President and Chairman, by the Fund’s CCO). These conflict of interest situations are listed below:

• service on the board of directors or governing board of a publicly traded entity;

• knowing acceptance of any investment opportunity or of any material gift or gratuity from any person or entity that does business, or desires to do business, with the relevant Fund. For these purposes, material gifts do not include (i) gifts from a single giver so long as their aggregate annual value does not exceed the equivalent of $100.00; (ii) attending business meals, business related conferences, sporting events and other entertainment events at the expense of a giver, so long as the expense is reasonable³ and both the Covered Person and the giver are present⁴; or (iii) gifts or meals/conferences/events received from the Covered Person’s employer;

³          Whether an entertainment expense is “reasonable” will vary depending on the circumstances. For example, under proposed FINRA (NASD) guidance (Proposed IM 3060, SEC Release No. 34-55765, May 15, 2007), generally, a business entertainment event that is so lavish or extensive in nature that an attendee would likely feel compelled to direct business to the sponsor of the event, or a business entertainment event that is intended or designed to cause, or would be reasonably judged to have the likely effect of causing the attendee to act in a manner that is inconsistent with the best interests of a Fund would be unreasonable per se.

⁴          In the event a Covered Person is a registered representative of the Funds’ principal underwriter, the aggregate annual gift value from a single giver shall not exceed $100.00 as required by the rules of FINRA.

Sarbanes-Oxley Code of Ethics

• any ownership interest in, or any consulting or employment relationship with, any entities doing business with the relevant Fund, other than a PIMCO-Affiliated Service Provider or an affiliate of a PIMCO-Affiliated Service Provider.⁵ This restriction shall not apply to or otherwise limit the ownership of publicly traded securities of such entities doing business with the relevant Fund so long as the Covered Person’s ownership does not exceed more than 2% of the outstanding securities of the relevant class; or

• knowingly have a direct or indirect financial interest in commissions, transaction charges or spreads paid by the relevant Fund for effecting portfolio transactions or for selling or redeeming shares of a Fund other than an interest arising from the Covered Person’s employment. This restriction shall not apply to or otherwise limit the direct or indirect ownership of publicly traded securities of any such company so long as the Covered Person’s ownership does not exceed more than 2% of the particular class of security outstanding.

III.       Disclosure and Compliance

• No Covered Person should knowingly misrepresent, or cause others to misrepresent, facts about the relevant Fund to others, whether within or outside such Fund, including to such Fund’s Board of Trustees and auditors, and to governmental regulators and self-regulatory organizations;

• each Covered Person should, to the extent appropriate within his area of responsibility, consult with other officers and employees of the Funds, applicable PIMCO Affiliated Service Providers, other service providers, or with counsel to the Funds with the goal of promoting full, fair, accurate, timely and understandable disclosure in the registration statements or periodic reports that the Funds file with, or submit to, the SEC (which, for sake of clarity, does not include any sales literature, omitting prospectuses, or “tombstone” advertising prepared by the relevant Fund’s principal underwriter(s)); and

• it is the responsibility of each Covered Person to promote compliance with the standards and restrictions imposed by applicable laws, rules and regulations.

However, PIMCO employees and PIMCO Investments LLC registered representatives are subject to the respective firm’s internal policies on accepting gifts and entertainment and must abide by the limitations imposed by such policies.

⁵         For purposes of the Code, an “affiliate” of a Service Provider is (a) any natural person or entity directly or indirectly owning, controlling, or holding with power to vote, 5% or more of the outstanding voting securities of the Service Provider; (b) any natural person or entity 5% or more of whose outstanding voting securities are directly or indirectly owned by, controlled, or held with power to vote, by the Service Provider; (c) any person directly or indirectly controlling, controlled by, or under common control with, the Service Provider; or (d) any officer, director, partner, copartner, or employee of the Service Provider.

IV.       Reporting and Accountability

Each Covered Person must:

• upon adoption of the Code (or thereafter as applicable, upon becoming a Covered Person), affirm in writing to the relevant Fund that he has received, read, and understood the Code;

• annually thereafter affirm to the relevant Fund that he has complied with the requirements of the Code by completing the Annual Certification of Compliance attached hereto as Exhibit C;

• provide full and fair responses to all questions asked in any Trustee and Officer Questionnaire provided by the relevant Fund as well as with respect to any supplemental request for information; and

• notify the President of the relevant Fund promptly if he or she is convinced to a moral certainty that there has been a material violation of this Code (with respect to violations by a President, the Covered Person shall report to the Chairman of the relevant Fund or, if the same person holds the titles of President and Chairman, to the Fund’s CCO).

The President of each Fund is responsible for applying this Code to specific situations in which questions are presented under it and, in consultation with the Fund’s CCO, has the authority to interpret this Code in any particular situation. However, any reviews sought by the President will be considered by the Chairman of the relevant Fund or, if the same person holds the titles of President and Chairman, by the Fund’s CCO.

The Funds will follow these procedures in investigating and enforcing this Code:

• the President will take all appropriate action to investigate any potential material violations reported to him, which actions may include the use of internal or external counsel, accountants or other personnel;

• if, after such investigation, the President believes that no material violation has occurred, the President is not required to take any further action;

• any matter that the President believes is a material violation will be reported to the applicable Fund’s CCO;

• if the CCO concurs that a material violation has occurred, it will inform and make a recommendation to the Fund’s Board of Trustees, which will consider appropriate action, which may include review of, and appropriate modifications to applicable policies and procedures; notification to appropriate personnel of a PIMCO-Affiliated Service Provider or its board; or a recommendation to dismiss the Covered Person; and

A Fund’s CCO or Board of Trustees may grant waivers under this Code, as each deems appropriate.

V.          Public Disclosure of Changes and Waivers

Any changes to this Code will, to the extent required by the SEC’s rules, be disclosed on the Fund’s website or in the Fund’s N-CSR. Any waivers under this Code relating to a Covered Person will, to the extent required by the SEC’s rules, be disclosed on the Fund’s website or in the Fund’s N-CSR.

VI.        Other Policies and Procedures

This Code shall be the sole code of ethics adopted by the Funds for purposes of Section 406 of the Sarbanes-Oxley Act and the rules and forms applicable to registered investment companies thereunder. Insofar as other policies or procedures of the Funds or the Funds’ PIMCO-Affiliated Service Providers govern or purport to govern the behavior or activities of the Covered Persons who are subject to this Code, they are superseded by this Code to the extent that they conflict with the provisions of this Code. The Funds’ and their PIMCO-Affiliated Service Providers’ codes of ethics under Rule 17j-1 under the 1940 Act and the PIMCO-Affiliated Service Providers’ more detailed compliance policies and procedures are separate requirements applying to the Covered Persons and others, and are not part of this Code.

This Code will not be interpreted or applied in any manner that would violate the legal rights of any Covered Person as an employee under applicable law. For example, nothing in this Code or the Exhibits attached hereto prohibits or in any way restricts any Covered Person from reporting possible violations of law or regulation to, otherwise communicating directly with, cooperating with or providing information to any governmental or regulatory body or any self-regulatory organization or making other disclosures that are protected under applicable law or regulations of the SEC or any other governmental or regulatory body or self-regulatory organization. A Covered Person does not need prior authorization of PIMCO, a Fund or a PIMCO-Affiliated Service Provider before taking any such action and is not required to inform PIMCO, a Fund or a PIMCO-Affiliated Service Provider if he or she chooses to take such action.

VII.       Amendments

Any material amendments to this Code must be approved or ratified by a majority vote of the Board of Trustees.

VIII.     Confidentiality

All reports and records prepared or maintained pursuant to this Code will be considered confidential and shall be maintained and protected accordingly. Except as otherwise required by law or this Code, such matters shall not be disclosed to anyone except as permitted by the Board of Trustees.

Annual Fund Operating Expenses

	Percentage of Net Assets Attributable to Common Shares (reflecting leverage attributable to ARPS and reverse repurchase agreements)
Management Fees(1)		0.83%
Dividend Cost on Preferred Shares(2)		0.71%
Interest Payments on Borrowed Funds(3)		1.78%
Other Expenses(4)		0.09%
Total Annual Fund Operating Expenses(5)		3.41%

1.  Management fees include fees payable to the Investment Manager for advisory services and for supervisory, administrative and other services. The Fund pays for the advisory, supervisory and administrative services it requires under what is essentially an all-in fee structure. Pursuant to an investment management agreement, PIMCO is paid a Management Fee of 0.76% of the Fund’s average daily net assets (including

daily net assets attributable to any preferred shares of the Fund that may be outstanding). The Fund (and not PIMCO) will be responsible for certain fees and expenses which are, reflected in the table above, that are not covered by the management fee under the investment management agreement. Please see Note 9, Fees and Expenses in the Notes to Financial Statements for an explanation of the management fee.

2.  Reflects the Fund’s outstanding Preferred Shares averaged over the fiscal year ended June 30, 2023, which represented 6.60% of the Fund’s total average managed assets (including the liquidation preference of outstanding Preferred Shares and assets attributable to reverse repurchase agreements), at an estimated annual dividend rate to the Fund of 8.11% (based on the weighted average Preferred Share dividend rate during the fiscal year ended June 30, 2023) and assumes the Fund will continue to pay Preferred Share dividends at the “maximum applicable rate” called for under the Fund’s Bylaws due to the ongoing failure of auctions for the ARPS. The actual dividend rate paid on the ARPS will vary over time in accordance with variations in market interest rates.

3.  Reflects the Fund’s use of leverage in the form of reverse repurchase agreements averaged over the fiscal year ended June 30, 2023, which represented 18.64% of the Fund’s total average managed assets (including assets attributable to reverse repurchase agreements), at an annual interest rate cost to the Fund of 3.44%, which is the weighted average interest rate cost during the fiscal year ended June 30, 2023. The actual amount of interest expense borne by the Fund will vary over time in accordance with the level of the Fund’s use of reverse repurchase agreements, dollar rolls and/or borrowings and variations in market interest rates. Borrowing expense is required to be treated as an expense of the Fund for accounting purposes. Any associated income or gains (or losses) realized from leverage obtained through such instruments is not reflected in the Annual Fund Operating Expenses table above, but would be reflected in the Fund’s performance results.

4.  Other expenses are estimated for the Fund’s fiscal year ending June 30, 2024.

5.  “Dividend Cost on Preferred Shares”, including distributions on Preferred Shares, and “Interest Payments on Borrowed Funds” are borne by the Fund separately from management fees paid to PIMCO. Excluding these expenses, Total Annual Fund Operating Expenses are 0.92%. Excluding only distributions on Preferred Shares of 0.71%, Total Annual Fund Operating Expenses are 2.70%.

Expense Example [Table Text Block]

Example

The following example illustrates the expenses that you would pay on a $1,000 investment in Common Shares of the Fund, assuming (1) that the Fund’s net assets do not increase or decrease, (2) that the Fund incurs total annual expenses of 3.41% of net assets attributable to Common Shares in years 1 through 10 (assuming assets attributable to Preferred Shares and reverse repurchase agreements representing 25.24% of the Fund’s total managed assets) and (3) a 5% annual return(1):

	1 Year		3 Years		5 Years		10 Years
Total Expenses Incurred	$	34	$	105	$	177	$	369

1  The example above should not be considered a representation of future expenses. Actual expenses may be higher or lower than those shown. The example assumes that the estimated Interest Payments on Borrowed Funds, Dividend Cost on Preferred Shares and Other Expenses set forth in the Annual Fund Operating Expenses table are accurate, that the rate listed under Total Annual Fund Operating Expenses remains the same each year and that all dividends and distributions are reinvested at NAV. Actual expenses may be greater or less than those assumed. Moreover, the Fund’s actual rate of return may be greater or less than the hypothetical 5% annual return shown in the example. The example does not include commissions or estimated offering expenses, which would cause the expenses shown in the example to increase.

Purpose of Fee Table , Note [Text Block]

The following table is intended to assist investors in understanding the fees and expenses (annualized) that an investor in Common Shares of the Fund would bear, directly or indirectly, as a result of an offering. The table reflects the use of leverage attributable to the Fund’s outstanding Preferred Shares and reverse repurchase agreements averaged over the fiscal year ended June 30, 2023 in an amount equal to 25.24% of the Fund’s total average managed assets (including assets attributable to such leverage), and shows Fund expenses as a percentage of net assets attributable to Common Shares. The percentage above does not reflect the Fund’s use of other forms of economic leverage, such as credit default swaps or other derivative instruments. The table and example below are based on the Fund’s capital structure as of June 30, 2023. The extent of the Fund’s assets attributable to leverage following an offering, and the Fund’s associated expenses, are likely to vary (perhaps significantly) from these assumptions.

Basis of Transaction Fees, Note [Text Block]

as a percentage of offering price

Other Expenses, Note [Text Block]

Other expenses are estimated for the Fund’s fiscal year ending June 30, 2024.

Management Fee not based on Net Assets, Note [Text Block]

Management fees include fees payable to the Investment Manager for advisory services and for supervisory, administrative and other services. The Fund pays for the advisory, supervisory and administrative services it requires under what is essentially an all-in fee structure. Pursuant to an investment management agreement, PIMCO is paid a Management Fee of 0.76% of the Fund’s average daily net assets (including

daily net assets attributable to any preferred shares of the Fund that may be outstanding). The Fund (and not PIMCO) will be responsible for certain fees and expenses which are, reflected in the table above, that are not covered by the management fee under the investment management agreement. Please see Note 9, Fees and Expenses in the Notes to Financial Statements for an explanation of the management fee.

Investment Objectives and Practices [Text Block]

The Funds’ Investment Objectives and Strategies

Unless otherwise noted, the information in this section is as of June 30, 2023.

The term “invest” includes both direct investing and indirect investing and the term “investments” includes both direct investments and indirect investments. For example, a Fund may invest indirectly by investing in derivatives or through wholly-owned subsidiaries (“Subsidiaries”), if applicable. The allocation of a Fund’s assets to a Subsidiary, if applicable, will vary over time and will likely not include all of the different types of investments described herein at any given time.

PIMCO High Income Fund (“PHK”)

The Fund’s primary investment objective is to seek high current income, with capital appreciation as a secondary objective.

The Fund seeks to achieve its investment objectives by utilizing a dynamic asset allocation strategy among multiple fixed income sectors in the global credit markets, which may include corporate debt (including, among other things, fixed-, variable- and floating-rate bonds, loans (including, but not limited to, bank and/or other syndicated loans and non-syndicated (private direct) loans), convertible securities and stressed debt securities issued by U.S. or foreign (non-U.S.) corporations or other business entities, including emerging market issuers), mortgage-related and other asset-backed securities, government and sovereign debt, taxable municipal bonds and other fixed-, variable- and floating-rate income-producing securities of U.S. and foreign issuers, including emerging market issuers. Aiming to identify securities that provide high current income and/or capital appreciation, the Fund focuses on duration management, credit quality analysis, risk management techniques and broad diversification among issuers, industries and sectors as well as other risk management techniques designed to manage default risk. The Fund may invest in investment grade debt securities and below investment grade debt securities (commonly referred to as “high yield” securities or “junk bonds”), including securities of stressed, distressed and defaulted issuers. The Fund cannot assure you that it will achieve its investment objectives, and you could lose all of your investment in the Fund.

Portfolio Management Strategies

Dynamic Allocation Strategy.  In managing the Fund, the Fund’s investment manager, PIMCO, employs an active approach to allocation among multiple fixed income sectors based on, among other things, market conditions, valuation assessments, economic outlook, credit market trends and other economic factors. With PIMCO’s macroeconomic analysis as the basis for top-down investment decisions, including geographic and credit sector emphasis, PIMCO manages the Fund with a focus on seeking income generating investment ideas across multiple fixed income sectors, with an emphasis on seeking opportunities in developed and emerging global credit markets. PIMCO may choose to focus on particular countries/regions, asset classes, industries and sectors to the exclusion of others at any time and from time to time based on market conditions and other factors. The relative value assessment within fixed income sectors draws on PIMCO’s regional and sector specialist insights. The Fund will observe various investment guidelines as summarized below.

Investment Selection Strategies.  Once the Fund’s top-down, portfolio positioning decisions have been made as described above, PIMCO selects particular investments for the Fund by employing a bottom-up, disciplined credit approach which is driven by fundamental, independent research within each sector/asset class represented in the Fund, with a focus on identifying securities and other instruments with solid and/or improving fundamentals.

PIMCO utilizes strategies that focus on credit quality analysis, duration management and other risk management techniques. PIMCO attempts to identify, through fundamental research driven by independent credit analysis and proprietary analytical tools, debt obligations and other income-producing securities that provide current income and/or opportunities for capital appreciation based on its analysis of the issuer’s credit characteristics and the position of the security in the issuer’s capital structure.

Consideration of yield is only one component of the portfolio managers’ approach in managing the Fund. PIMCO also attempts to identify investments that may appreciate in value based on PIMCO’s assessment of the issuer’s credit characteristics, forecast for interest rates and outlook for particular countries/regions, currencies, industries, sectors and the global economy and bond markets generally.

Credit Quality.  The Fund may invest in debt instruments that are, at the time of purchase, rated below investment grade, or that are unrated but determined by PIMCO to be of comparable quality. The Fund will not normally invest more than 20% of its total assets in debt instruments, other than mortgage-related and other asset-backed securities, that are, at the time of purchase, rated CCC or lower by S&P and Fitch and Caa1 or lower by Moody’s, or that are unrated but determined by PIMCO to be of comparable quality. The Fund may

invest without limit in mortgage-related and other asset-backed securities regardless of rating (i.e., of any credit quality). Subject to this 20% restriction, the Fund may invest any portion of its assets (or none) in issuers of any credit quality (including bonds in the lowest ratings categories). For purposes of applying the foregoing policies, in the case of securities with split ratings (i.e., a security receiving two different ratings from two different rating agencies), the Fund will apply the higher of the applicable ratings. Subject to the aforementioned investment restrictions, the Fund may invest in securities of stressed issuers, which include securities at risk of being in default as to the repayment of principal and/or interest at the time of acquisition by the Fund or that are rated in the lower rating categories by one or more nationally recognized statistical rating organizations (for example, Ca or lower by Moody’s or CC or lower by S&P or Fitch) or, if unrated, are determined by PIMCO to be of comparable quality. Debt instruments of below investment grade quality are regarded as having predominantly speculative characteristics with respect to capacity to pay interest and to repay principal, and are commonly referred to as “high yield” securities or “junk bonds.” Debt instruments in the lowest investment grade category also may be considered to possess some speculative characteristics. The Fund may, for hedging, investment or leveraging purposes, make use of credit default swaps, which are contracts whereby one party makes periodic payments to a counterparty in exchange for the right to receive from the counterparty a payment equal to the par (or other agreed-upon) value of a referenced debt obligation in the event of a default or other credit event by the issuer of the debt obligation.

Independent Credit Analysis.  PIMCO relies primarily on its own analysis of the credit quality and risks associated with individual debt instruments considered for the Fund, rather than relying exclusively on rating agencies or third-party research. The Fund’s portfolio managers utilize this information in an attempt to manage credit risk and/or to identify issuers, industries or sectors that are undervalued and/or offer attractive yields relative to PIMCO’s assessment of their credit characteristics. This aspect of PIMCO’s capabilities will be particularly important to the extent that the Fund invests in high yield securities and in securities of emerging market issuers.

Duration Management.  It is expected that the Fund normally will have a short to intermediate average portfolio duration (i.e., within a zero to eight year (0 to 8) range), as calculated by PIMCO, although it may be shorter or longer at any time or from time to time depending on market conditions and other factors. While the Fund seeks to maintain a short to intermediate average portfolio duration, there is no limit on the maturity or duration of any individual security in which the Fund may invest. Duration is a measure used to determine the sensitivity of a security’s price to changes in interest rates. The Fund’s

duration strategy may entail maintaining a negative average portfolio duration from time to time, meaning the portfolio would tend to increase in value in response to an increase in interest rates. If the Fund has a negative average portfolio duration, a 1% increase in interest rates would tend to correspond to a 1% increase in the value of the Fund’s debt portfolio for every year of negative duration. A negative average portfolio duration would potentially benefit the portfolio in an environment of rising market interest rates, but would generally adversely impact the portfolio in an environment of falling or neutral market interest rates. The Fund may use various derivatives strategies to manage (increase or decrease) the dollar-weighted average effective duration of the Fund’s portfolio. PIMCO may also utilize certain strategies, including without limitation investments in structured notes or interest rate futures contracts or swap, cap, floor or collar transactions, for the purpose of reducing the interest rate sensitivity of the Fund’s portfolio, although there is no assurance that it will do so or that such strategies will be successful.

Risk Factors [Table Text Block]

Principal Risks of the Funds (Unaudited)

The factors that are most likely to have a material effect on a particular Fund’s portfolio as a whole are called “principal risks.” Each Fund is subject to the principal risks indicated below, as applicable, whether through direct investments, investments by a subsidiary (if applicable) or derivative positions. Each Fund may be subject to additional risks other than those described below because the types of investments made by a Fund can change over time.

Anti-Takeover Provisions

The Fund’s Amended and Restated Agreement and Declaration of Trust (the “Declaration of Trust”), as applicable, includes provisions that could limit the ability of other entities or persons to acquire control of the Fund or to convert the Fund to open-end status. These provisions in the Declaration of Trust could have the effect of depriving the holders (“Common Shareholders”) of the Fund’s common shares of beneficial interest (“Common Shares”) of opportunities to sell their Common Shares at a premium over the then-current market price of the Common Shares or at NAV.

Asset Allocation Risk

The Fund’s investment performance depends upon how its assets are allocated and reallocated. A principal risk of investing in the Fund is that PIMCO may make less than optimal or poor asset allocation decisions. PIMCO employs an active approach to allocation among multiple fixed-income sectors, but there is no guarantee that such allocation techniques will produce the desired results. It is possible that PIMCO will focus on an investment that performs poorly or underperforms other investments under various market conditions. You could lose money on your investment in the Fund as a result of these allocation decisions.

Call Risk

Call risk refers to the possibility that an issuer may exercise its right to redeem a fixed income security earlier than expected (a call). Issuers may call outstanding securities prior to their maturity for a number of reasons (e.g., declining interest rates, changes in credit spreads and improvements in the issuer’s credit quality). If an issuer calls a security in which the Fund has invested, the Fund may not recoup the full amount of its initial investment and may be forced to reinvest in lower-yielding securities, securities with greater credit risks or securities with other, less favorable features.

Certain Affiliations

Certain broker-dealers may be considered to be affiliated persons of the Fund and/or the Investment Manager due to their possible affiliations with Allianz SE, the ultimate parent of the Investment Manager, or another Allianz entity. Allianz Asset Management of America LP merged with Allianz Asset Management of America LLC (“Allianz Asset Management”), with the latter being the surviving entity, effective January 1, 2023. Following the merger, Allianz Asset

Management is PIMCO LLC’s managing member and direct parent entity. Absent an exemption from the SEC or other regulatory relief, the Fund is generally precluded from effecting certain principal transactions with affiliated brokers, and its ability to purchase securities being underwritten by an affiliated broker or a syndicate including an affiliated broker, or to utilize affiliated brokers for agency transactions, is subject to restrictions. This could limit the Fund’s ability to engage in securities transactions and take advantage of market opportunities.

The Fund has received exemptive relief from the SEC that, to the extent the Fund relies on such relief, permits it to (among other things) co-invest with certain other persons, including certain affiliates of the Investment Manager and certain public or private funds managed by the Investment Manager and its affiliates, subject to certain terms and conditions. The exemptive relief from the SEC with respect to co-investments imposes extensive conditions on any co-investments made in reliance on such relief.

Collateralized Bond Obligations, Collateralized Loan Obligations and Collateralized Debt Obligations Risk

CBOs, CLOs and CDOs may charge management fees and administrative expenses. For CBOs, CLOs and CDOs, the cash flows from the trust are split into two or more portions, called tranches, varying in risk and yield. The riskiest portion is the equity tranche which generally bears losses in connection with the first defaults, if any, on the bonds or loans in the trust. A senior tranche from a CLO, CBO and CDO trust typically has higher credit ratings and lower yields than the underlying securities. CLO, CBO and CDO tranches, even senior ones, can experience substantial losses due to actual defaults, increased sensitivity to defaults due to collateral default and disappearance of protecting tranches, market anticipation of defaults and aversion to CLO, CBO or other CDO securities. The risks of an investment in a CLO, CBO or other CDO depend largely on the type of the collateral securities and the class/tranche of the instrument in which the Fund invests. Normally, CLOs, CBOs and other CDOs are privately offered and sold, and thus are not registered under the securities laws. Investments in CLOs, CBOs and CDOs may be or become illiquid. In addition to the normal risks associated with debt instruments (e.g., interest rate risk and credit risk), CLOs, CBOs and CDOs carry additional risks including, but not limited to: (i) the possibility that distributions from the collateral will not be adequate to make interest or other payments; (ii) the risk that the quality of the collateral may decline in value or default; (iii) the risk that the Fund may invest in CBOs, CLOs or other CDOs that are subordinate to other classes; and (iv) the risk that the complex structure of the security may not be fully understood at the time of investment and may produce disputes with the issuer or others and may produce unexpected investment results.

Confidential Information Access Risk

In managing the Fund (and other PIMCO clients), PIMCO may from time to time have the opportunity to receive material, non-public information (“Confidential Information”) about the issuers of certain investments, including, without limitation, senior floating rate loans, other loans and related investments being considered for acquisition by the Fund or held in the Fund’s portfolio. For example, an issuer of privately placed loans considered by the Fund may offer to provide PIMCO with financial information and related documentation regarding the issuer that is not publicly available. Pursuant to applicable policies and procedures, PIMCO may (but is not required to) seek to avoid receipt of Confidential Information from the issuer so as to avoid possible restrictions on its ability to purchase and sell investments on behalf of the Fund and other clients to which such Confidential Information relates. In such circumstances, the Fund (and other PIMCO clients) may be disadvantaged in comparison to other investors, including with respect to the price the Fund pays or receives when it buys or sells an investment. Further, PIMCO’s and the Fund’s abilities to assess the desirability of proposed consents, waivers or amendments with respect to certain investments may be compromised if they are not privy to available Confidential Information. PIMCO may also determine to receive such Confidential Information in certain circumstances under its applicable policies and procedures. If PIMCO intentionally or unintentionally comes into possession of Confidential Information, it may be unable, potentially for a substantial period of time, to purchase or sell investments to which such Confidential Information relates.

Contingent Convertible Securities Risk

Contingent convertible securities (“CoCos”) have no stated maturity, have fully discretionary coupons and are typically issued in the form of subordinated debt instruments. CoCos generally either convert into equity or have their principal written down (including potentially to zero) upon the occurrence of certain triggering events (“triggers”) linked to regulatory capital thresholds or regulatory actions relating to the issuer’s continued viability. As a result, an investment by the Fund in CoCos is subject to the risk that coupon (i.e., interest) payments may be cancelled by the issuer or a regulatory authority in order to help the issuer absorb losses and the risk of total loss. An investment by the Fund in CoCos is also subject to the risk that, in the event of the liquidation, dissolution or winding-up of an issuer prior to a trigger event, the Fund’s rights and claims will generally rank junior to the claims of holders of the issuer’s other debt obligations and CoCos may also be treated as junior to an issuer’s other obligations and securities. In addition, if CoCos held by the Fund are converted into the issuer’s underlying equity securities following a trigger event, the Fund’s holding may be further subordinated due to the conversion from a debt to equity instrument. Further, the value of an investment in CoCos is unpredictable and will be

influenced by many factors and risks, including interest rate risk, credit risk, market risk and liquidity risk. An investment by the Fund in CoCos may result in losses to the Fund.

Convertible Securities Risk

The market values of convertible securities may decline as interest rates increase and, conversely, may increase as interest rates decline. A convertible security’s market value, however, tends to reflect the market price of the common stock of the issuing company when that stock price approaches or is greater than the convertible security’s “conversion price.” The conversion price is defined as the predetermined price at which the convertible security could be exchanged for the associated stock. As the market price of the underlying common stock declines, the price of the convertible security tends to be influenced more by the yield of the convertible security. Thus, it may not decline in price to the same extent as the underlying common stock. In the event of a liquidation of the issuing company, holders of convertible securities may be paid before the company’s common stockholders but after holders of any senior debt obligations of the company. Consequently, the issuer’s convertible securities generally entail less risk than its common stock but more risk than its other debt obligations. Convertible securities are often rated below investment grade or not rated.

Counterparty Risk

The Fund will be subject to credit risk with respect to the counterparties to the derivative contracts and other instruments entered into by the Fund or held by special purpose or structured vehicles in which the Fund invests. In the event that the Fund enters into a derivative transaction with a counterparty that subsequently becomes insolvent or becomes the subject of a bankruptcy case, the derivative transaction may be terminated in accordance with its terms and the Fund’s ability to realize its rights under the derivative instrument and its ability to distribute the proceeds could be adversely affected. If a counterparty becomes bankrupt or otherwise fails to perform its obligations under a derivative contract due to financial difficulties, the Fund may experience significant delays in obtaining any recovery (including recovery of any collateral it has provided to the counterparty) in a dissolution, assignment for the benefit of creditors, liquidation, winding-up, bankruptcy or other analogous proceeding. In addition, in the event of the insolvency of a counterparty to a derivative transaction, the derivative transaction would typically be terminated at its fair market value. If the Fund is owed this fair market value in the termination of the derivative transaction and its claim is unsecured, the Fund will be treated as a general creditor of such counterparty and will not have any claim with respect to any underlying security or asset. The Fund may obtain only a limited recovery or may obtain no recovery in such circumstances. While the

Fund may seek to manage its counterparty risk by transacting with a number of counterparties, concerns about the solvency of, or a default by, one large market participant could lead to significant impairment of liquidity and other adverse consequences for other counterparties.

“Covenant-Lite” Obligations Risk

Covenant-lite obligations contain fewer maintenance covenants than other obligations, or no maintenance covenants, and may not include terms that allow the lender to monitor the performance of the borrower and declare a default if certain criteria are breached. Covenant-lite loans may carry more risk than traditional loans as they allow individuals and corporations to engage in activities that would otherwise be difficult or impossible under a covenant-heavy loan agreement. In the event of default, covenant-lite loans may exhibit diminished recovery values as the lender may not have the opportunity to negotiate with the borrower prior to default.

Credit Default Swaps Risk

Credit default swap agreements may involve greater risks than if the Fund had invested in the reference obligation directly since, in addition to general market risks, credit default swaps are subject to leverage risk, illiquidity risk, counterparty risk and credit risk. A buyer generally also will lose its investment and recover nothing should no credit event occur and the swap is held to its termination date. If a credit event were to occur, the value of any deliverable obligation received by the seller (if any), coupled with the upfront or periodic payments previously received, may be less than the full notional value it pays to the buyer, resulting in a loss of value to the seller. When the Fund acts as a seller of a credit default swap, it is exposed to many of the same risks of leverage described herein. As the seller, the Fund would receive a stream of payments over the term of the swap agreement provided that no event of default has occurred with respect to the referenced debt obligation upon which the swap is based. The Fund would effectively add leverage to its portfolio because, if a default occurs, the stream of payments may stop and, in addition to its total net assets, the Fund would be subject to investment exposure on the notional amount of the swap.

Although the Fund may seek to realize gains by selling credit default swaps that increase in value, to realize gains on selling credit default swaps, an active secondary market for such instruments must exist or the Fund must otherwise be able to close out these transactions at advantageous times. In addition to the risk of losses described above, if no such secondary market exists or the Fund is otherwise unable to close out these transactions at advantageous times, selling credit default swaps may not be profitable for the Fund.

The market for credit default swaps has become more volatile as the creditworthiness of certain counterparties has been questioned and/or

downgraded. The Fund will be subject to credit risk with respect to the counterparties to the credit default swap contract (whether a clearing corporation or another third party). If a counterparty’s credit becomes significantly impaired, multiple requests for collateral posting in a short period of time could increase the risk that the Fund may not receive adequate collateral. The Fund may exit its obligations under a credit default swap only by terminating the contract and paying applicable breakage fees, or by entering into an offsetting credit default swap position, which may cause the Fund to incur more losses.

Credit Risk

The Fund could lose money if the issuer or guarantor of a fixed income security (including a security purchased with securities lending collateral), or the counterparty to a derivatives contract, repurchase agreement or a loan of portfolio securities is unable or unwilling, or is perceived (whether by market participants, rating agencies, pricing services or otherwise) as unable or unwilling, to make timely principal and/or interest payments or to otherwise honor its obligations. The risk that such issuer, guarantor or counterparty is less willing or able to do so is heightened in market environments where interest rates are rising. The downgrade of the credit of a security held by the Fund may decrease its value. Measures such as average credit quality may not accurately reflect the true credit risk of the Fund. This is especially the case if the Fund consists of securities with widely varying credit ratings. Securities are subject to varying degrees of credit risk, which are often reflected in credit ratings. Credit risk is greater to the extent the Fund uses leverage or derivatives. Rising or high interest rates may deteriorate the credit quality of an issuer or counterparty, particularly if an issuer or counterparty faces challenges rolling or refinancing its obligations.

CSDR Related Risk

The European Union has adopted a settlement discipline regime under Regulation (EU) No 909/2014 and the Settlement Discipline RTS as they may be modified from time to time (“CSDR”), which will have phased compliance dates. It aims to reduce the number of settlement fails that occur in EEA central securities depositories (“CSDs”) and address settlement fails where they occur. The key elements of the regime are: (i) mandatory buy-ins — if a settlement fail continues for a specified period of time after the intended settlement date, a buy-in process must be initiated to effect the settlement; (ii) cash penalties — EEA CSDs are required to impose cash penalties on participants that cause settlement fails and distribute these to receiving participants; and (iii) allocations and confirmations — EEA investment firms are required to take measures to prevent settlement fails, including putting in place arrangements with their professional clients to communicate securities allocations and transaction confirmations. These requirements apply to transactions in transferable securities (e.g., shares and bonds), money market instruments, units in funds

and emission allowances that are to be settled via an EEA CSD and, in the case of cash penalties and buy-in requirements only, are admitted to trading or traded on an EEA trading venue or cleared by an EEA central counterparty. If the Fund enters into in-scope transactions, the CSDR settlement discipline regime may result in increased operational and compliance costs being borne directly or indirectly by the Fund. CSDR may also affect liquidity and increase trading costs associated with relevant securities. If in-scope transactions are subject to additional expenses and penalties as a consequence of the CSDR settlement discipline regime, such expenses and penalties may be charged to the relevant Fund.

Currency Risk

If the Fund invests directly in foreign (non-U.S.) currencies or in securities that trade in, and receive revenues in, foreign (non-U.S.) currencies, or in derivatives or other instruments that provide exposure to foreign (non-U.S.) currencies, it will be subject to the risk that those currencies will decline in value relative to the U.S. dollar, or, in the case of hedging positions, that the U.S. dollar will decline in value relative to the currency being hedged. Although the Fund may attempt to hedge its currency exposure into the U.S. dollar, it may not be successful in reducing the effects of currency fluctuations. The Fund may also hedge from one foreign currency to another. In addition, the Fund’s use of currency hedging may not be successful and the use of such strategies may lower the Fund’s potential returns.

Investments denominated in foreign (non-U.S.) currencies or that trade in and receive revenues in, foreign (non-U.S.) currencies, derivatives or other instruments that provide exposure to foreign (non-U.S.) currencies, are subject to the risk that those currencies will decline in value relative to the U.S. dollar, or, in the case of hedging positions, that the U.S. dollar will decline in value relative to the currency being hedged.

Currency rates in foreign (non-U.S.) countries may fluctuate significantly over short periods of time for a number of reasons, including changes in interest rates, rates of inflation, balance of payments and governmental surpluses or deficits, intervention (or the failure to intervene) by U.S. or foreign (non-U.S.) governments, central banks or supranational entities such as the International Monetary Fund, or by the imposition of currency controls or other political developments in the United States or abroad. These fluctuations may have a significant adverse impact on the value of the Fund’s portfolio and/or the level of Fund distributions made to Common Shareholders. There is no assurance that a hedging strategy, if used, will be successful.

Moreover, currency hedging techniques may be unavailable with respect to emerging market currencies. As a result, the Fund’s investments in foreign currency-denominated, and especially emerging market-currency denominated, securities may reduce the returns of the Fund.

Cyber Security Risk

As the use of technology has become more prevalent in the course of business, the Fund is potentially more susceptible to operational and information security risks resulting from breaches in cyber security. A breach in cyber security refers to both intentional and unintentional cyber events from outside threat actors or internal resources that may, among other things, cause the Fund to lose proprietary information, suffer data corruption and/or destruction, lose operational capacity, result in the unauthorized release or other misuse of confidential information, or otherwise disrupt normal business operations. Cyber security breaches may involve unauthorized access to the Fund’s digital information systems (e.g., through “hacking” or malicious software coding), and may come from multiple sources, including outside attacks such as denial-of-service attacks (i.e., efforts to make network services unavailable to intended users) or cyber extortion, including exfiltration of data held for ransom and/or “ransomware” attacks that renders systems inoperable until ransom is paid, or insider actions. In addition, cyber security breaches involving the Fund’s third party service providers (including but not limited to advisers, sub-advisers, administrators, transfer agents, custodians, vendors, suppliers, distributors and other third parties), trading counterparties or issuers in which the Fund invests can also subject the Fund to many of the same risks associated with direct cyber security breaches or extortion of company data. Moreover, cyber security breaches involving trading counterparties or issuers in which the Fund invests could adversely impact such counterparties or issuers and cause the Fund’s investments to lose value. In addition, work-from-home arrangements by the Fund, the Investment Manager or their service providers could increase all of the above risks, create additional data and information accessibility concerns, and make the Fund, the Investment Manager or their service providers susceptible to operational disruptions, any of which could adversely impact their operations.

Cyber security failures or breaches may result in financial losses to the Fund and its shareholders. These failures or breaches may also result in disruptions to business operations, potentially resulting in financial losses; interference with the Fund’s ability to calculate its NAV, process shareholder transactions or otherwise transact business with shareholders; impediments to trading; violations of applicable privacy and other laws; regulatory fines; penalties; third party claims in litigation; reputational damage; reimbursement or other compensation costs; additional compliance and cyber security risk management costs and other adverse consequences. In addition, substantial costs may be incurred in order to prevent any cyber incidents in the future.

Like with operational risk in general, the Fund has established business continuity plans and risk management systems designed to reduce the risks associated with cyber security. However, there are

inherent limitations in these plans and systems, including that certain risks may not have been identified, in large part because different or unknown threats may emerge in the future. As such, there is no guarantee that such efforts will succeed, especially because the Fund does not directly control the cyber security systems of issuers in which the Fund may invest, trading counterparties or third party service providers to the Fund. Such entities have experienced cyber attacks and other attempts to gain unauthorized access to systems from time to time, and there is no guarantee that efforts to prevent or mitigate the effects of such attacks or other attempts to gain unauthorized access will be successful. There is also a risk that cyber security breaches may not be detected. The Fund and its shareholders may suffer losses as a result of a cyber security breach related to the Fund, its service providers, trading counterparties or the issuers in which the Fund invests.

Debt Securities Risk

Debt securities are generally subject to the risks described below and further herein:

Issuer risk.  The value of debt securities may decline for a number of reasons that directly relate to the issuer, such as management performance, financial leverage, reduced demand for the issuer’s goods and services, historical and prospective earnings of the issuer and the value of the assets of the issuer.

Interest rate risk.  The market value of debt securities changes in response to interest rate changes and other factors. Interest rate risk is the risk that prices of debt securities will increase as interest rates fall and decrease as interest rates rise, which would be reflected in the Fund’s NAV. The Fund may lose money if short-term or long-term interest rates rise sharply in a manner not anticipated by the Fund’s management. Moreover, because rates on certain floating rate debt securities typically reset only periodically, changes in prevailing interest rates (and particularly sudden and significant changes) can be expected to cause some fluctuations in the NAV of the Fund to the extent that it invests in floating rate debt securities.

Prepayment risk.  During periods of declining interest rates, borrowers may prepay principal. This may force the Fund to reinvest in lower yielding securities, resulting in a possible decline in the Fund’s income and distributions.

Credit risk.  Credit risk is the risk that one or more debt securities in the Fund’s portfolio will decline in price or fail to pay interest or principal when due because the issuer of the security experiences a decline in its financial status. Credit risk is increased when a portfolio security is downgraded or the perceived creditworthiness of the issuer deteriorates.

Reinvestment risk.  Reinvestment risk is the risk that income from the Fund’s portfolio will decline if the Fund invests the proceeds from matured, traded or called fixed income securities at market interest rates that are below the portfolio’s current earnings rate.

Duration and maturity risk.  The Fund may seek to adjust the duration or maturity of its investments in debt securities based on its assessment of current and projected market conditions. The Fund may incur costs in seeking to adjust the average duration or maturity of its portfolio of debt securities. There can be no assurances that the Fund’s assessment of current and projected market conditions will be correct or that any strategy to adjust duration or maturity will be successful.

In addition, from time to time, uncertainty regarding the status of negotiations in the U.S. government to increase the statutory debt ceiling could impact the creditworthiness of the United States and could impact the liquidity and value of U.S. Government and other securities and ultimately the Fund.

Derivatives Risk

The Fund may, but is not required to, utilize a variety of derivative instruments (both long and short positions) for investment or risk management purposes. Derivatives are financial contracts whose value depends on, or is derived from, the value of an underlying asset, reference rate or index. For example, the Fund may use derivative instruments for purposes of increasing liquidity, providing efficient portfolio management, broadening investment opportunities (including taking short or negative positions), implementing a tax or cash management strategy, gaining exposure to a particular security or segment of the market, modifying the effective duration of the Fund’s portfolio investments and/or enhancing total return.

The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. Derivatives and other similar instruments (referred to collectively as “derivatives”), which may increase market exposure are subject to a number of risks including leverage risk, liquidity risk (which may be heightened for highly customized derivatives), interest rate risk, market risk, counterparty (including credit) risk, operational risk (such as documentation issues, settlement issues and systems failures), legal risk (such as insufficient documentation, insufficient capacity or authority of a counterparty, and issues with the legality or enforceability of a contract), counterparty risk, tax risk and management risk, as well as risks arising from changes in applicable requirements, risks arising from margin requirements and risks arising from mispricing or valuation complexity. They also involve the risk that changes in the value of a derivative instrument may not correlate perfectly with the underlying asset, rate or index. By investing in a

derivative instrument, the Fund could lose more than the initial amount invested, and derivatives may increase the volatility of the Fund, especially in unusual or extreme market conditions. Certain derivatives have the potential for unlimited loss, regardless of the size of the initial investment. The 1940 Act and related rules no longer require asset segregation for derivatives transactions, however asset segregation and posting of collateral may still be utilized for risk management or other purposes. The Fund may be required to hold additional cash or sell other investments in order to obtain cash to close out a position and changes in the value of a derivative may also create margin delivery or settlement payment obligations for the Fund. Also, suitable derivative transactions may not be available in all circumstances and there can be no assurance that the Fund will engage in these transactions to reduce exposure to other risks when that would be beneficial or that, if used, such strategies will be successful. The Fund’s use of derivatives may increase or accelerate the amount of taxes payable by Common Shareholders.

Over-the-counter (“OTC”) derivatives are also subject to the risk that a counterparty to the transaction will not fulfill its contractual obligations to the other party, as many of the protections afforded to centrally cleared derivative transactions might not be available for OTC derivatives. The primary credit risk on derivatives that are exchange-traded or traded through a central clearing counterparty resides with the Fund’s clearing broker, or the clearinghouse itself.

Participation in the markets for derivative instruments involves investment risks and transaction costs to which the Fund may not be subject absent the use of these strategies. The skills needed to successfully execute derivative strategies may be different from those needed for other types of transactions. If the Fund incorrectly forecasts the value and/or creditworthiness of securities, currencies, interest rates, counterparties or other economic factors involved in a derivative transaction, the Fund might have been in a better position if the Fund had not entered into such derivative transaction. In evaluating the risks and contractual obligations associated with particular derivative instruments, it is important to consider that certain derivative transactions may be modified or terminated only by mutual consent of the Fund and its counterparty.

Therefore, it may not be possible for the Fund to modify, terminate, or offset the Fund’s obligations or the Fund’s exposure to the risks associated with a derivative transaction prior to its scheduled termination or maturity date, which may create a possibility of increased volatility and/or decreased liquidity to the Fund. Hedges are sometimes subject to imperfect matching between the derivative and the underlying instrument, and there can be no assurance that the Fund’s hedging transactions will be effective. In such case, the Fund may lose money.

Because the markets for certain derivative instruments (including markets located in foreign countries) are relatively new and still developing, appropriate derivative transactions may not be available in all circumstances for risk management or other purposes. Upon the expiration of a particular contract, the Fund may wish to retain the Fund’s position in the derivative instrument by entering into a similar contract but may be unable to do so if the counterparty to the original contract is unwilling to enter into the new contract and no other appropriate counterparty can be found. When such markets are unavailable, the Fund will be subject to increased liquidity and investment risk.

The Fund may enter into opposite sides of interest rate swap and other derivatives for the principal purpose of generating distributable gains on the one side (characterized as ordinary income for tax purposes) that are not part of the Fund’s duration or yield curve management strategies (“paired swap transactions”), and with a substantial possibility that the Fund will experience a corresponding capital loss and decline in NAV with respect to the opposite side transaction (to the extent it does not have corresponding offsetting capital gains). Consequently, Common Shareholders may receive distributions and owe tax on amounts that are effectively a taxable return of the shareholder’s investment in the Fund, at a time when their investment in the Fund has declined in value, which tax may be at ordinary income rates. The tax treatment of certain derivatives in which the Fund invests may be unclear and thus subject to recharacterization. Any recharacterization of payments made or received by the Fund pursuant to derivatives potentially could affect the amount, timing or character of Fund distributions. In addition, the tax treatment of such investment strategies may be changed by regulation or otherwise.

When a derivative is used as a hedge against a position that the Fund holds, any loss generated by the derivative generally should be substantially offset by gains on the hedged investment, and vice versa. Although hedging can reduce or eliminate losses, it can also reduce or eliminate gains. Hedges are sometimes subject to imperfect matching between the derivative and the underlying instrument, and there can be no assurance that the Fund’s hedging transactions will be effective. The regulation of the derivatives markets has increased over the past several years, and additional future regulation of the derivatives markets may make derivatives more costly, may limit the availability or reduce the liquidity of derivatives, or may otherwise adversely affect the value or performance of derivatives. Any such adverse future developments could impair the effectiveness or raise the costs of the Fund’s derivative transactions, impede the employment of the Fund’s derivatives strategies, or adversely affect the Fund’s performance.

Distressed and Defaulted Securities Risk

Investments in the securities of financially distressed issuers involve substantial risks, including the risk of default. Distressed securities generally trade significantly below “par” or full value because investments in such securities and debt of distressed issuers or issuers in default are considered speculative and involve substantial risks in addition to the risks of investing in high-yield bonds. Such investments may be in default at the time of investment. In addition, these securities may fluctuate more in price, and are typically less liquid. The Fund also will be subject to significant uncertainty as to when, and in what manner, and for what value obligations evidenced by securities of financially distressed issuers will eventually be satisfied. Defaulted obligations might be repaid only after lengthy workout or bankruptcy proceedings, during which the issuer might not make any interest or other payments. In any such proceeding relating to a defaulted obligation, the Fund may lose its entire investment or may be required to accept cash or securities with a value substantially less than its original investment. Moreover, any securities received by the Fund upon completion of a workout or bankruptcy proceeding may be less liquid, speculative or restricted as to resale. Similarly, if the Fund participates in negotiations with respect to any exchange offer or plan of reorganization with respect to the securities of a distressed issuer, the Fund may be restricted from disposing of such securities. To the extent that the Fund becomes involved in such proceedings, the Fund may have a more active participation in the affairs of the issuer than that assumed generally by an investor. The Fund may incur additional expenses to the extent it is required to seek recovery upon a default in the payment of principal or interest on its portfolio holdings.

Also among the risks inherent in investments in a troubled issuer is that it frequently may be difficult to obtain information as to the true financial condition of such issuer. PIMCO’s judgments about the credit quality of a financially distressed issuer and the relative value of its securities may prove to be wrong.

Distribution Rate Risk

Although the Fund may seek to maintain level distributions, the Fund’s distribution rates may be affected by numerous factors, including but not limited to changes in realized and projected market returns, fluctuations in market interest rates, Fund performance, and other factors. There can be no assurance that a change in market conditions or other factors will not result in a change in the Fund’s distribution rate or that the rate will be sustainable in the future.

For instance, during periods of low or declining interest rates, the Fund’s distributable income and dividend levels may decline for many reasons. For example, the Fund may have to deploy uninvested assets (whether from sales of Fund shares, proceeds from matured, traded or called debt obligations or other sources) in new, lower yielding

instruments. Additionally, payments from certain instruments that may be held by the Fund (such as variable and floating rate securities) may be negatively impacted by declining interest rates, which may also lead to a decline in the Fund’s distributable income and dividend levels.

Emerging Markets Risk

Foreign (non U.S.) investment risk may be particularly high to the extent that the Fund invests in securities of issuers based in or doing business in emerging market countries or invests in securities denominated in the currencies of emerging market countries. Investing in securities of issuers based in or doing business in emerging markets entails all of the risks of investing in foreign securities noted above, but to a heightened degree.

Investments in emerging market countries pose a greater degree of systemic risk (i.e., the risk of a cascading collapse of multiple institutions within a country, and even multiple national economies). The inter-relatedness of economic and financial institutions within and among emerging market economies has deepened over the years, with the effect that institutional failures and/or economic difficulties that are of initially limited scope may spread throughout a country, a region or all or most emerging market countries. This may undermine any attempt by the Fund to reduce risk through geographic diversification of its portfolio.

There is a heightened possibility of imposition of withholding taxes on interest or dividend income generated from emerging market securities. Governments of emerging market countries may engage in confiscatory taxation or expropriation of income and/or assets to raise revenues or to pursue a domestic political agenda. In the past, emerging market countries have nationalized assets, companies and even entire sectors, including the assets of foreign investors, with inadequate or no compensation to the prior owners. There can be no assurance that the Fund will not suffer a loss of any or all of its investments, or interest or dividends thereon, due to adverse fiscal or other policy changes in emerging market countries.

There is also a greater risk that an emerging market government may take action that impedes or prevents the Fund from taking income and/or capital gains earned in the local currency and converting into U.S. dollars (i.e., “repatriating” local currency investments or profits). Certain emerging market countries have sought to maintain foreign exchange reserves and/or address the economic volatility and dislocations caused by the large international capital flows by controlling or restricting the conversion of the local currency into other currencies. This risk tends to become more acute when economic conditions otherwise worsen. There can be no assurance that if the Fund earns income or capital gains in an emerging market currency or PIMCO otherwise seeks to withdraw the Fund’s investments from a

given emerging market country, capital controls imposed by such country will not prevent, or cause significant expense, or delay in, doing so.

Bankruptcy law and creditor reorganization processes may differ substantially from those in the United States, resulting in greater uncertainty as to the rights of creditors, the enforceability of such rights, reorganization timing and the classification, seniority and treatment of claims. In certain emerging market countries, although bankruptcy laws have been enacted, the process for reorganization remains highly uncertain. In addition, it may be impossible to seek legal redress against an issuer that is a sovereign state.

Emerging market countries typically have less established legal, accounting, recordkeeping and financial reporting systems than those in more developed markets, which may reduce the scope or quality of financial information available to investors. Governments in emerging market countries are often less stable and more likely to take extra-legal action with respect to companies, industries, assets, or foreign ownership than those in more developed markets. Moreover, it can be more difficult for investors to bring litigation or enforce judgments against issuers in emerging markets or for U.S. regulators to bring enforcement actions against such issuers. The Fund may also be subject to emerging markets risk if it invests in derivatives or other securities or instruments whose value or return are related to the value or returns of emerging markets securities.

Other heightened risks associated with emerging markets investments include without limitation (i) risks due to less social, political and economic stability; (ii) the smaller size of the market for such securities and a lower volume of trading, resulting in a lack of liquidity and in price volatility; (iii) certain national policies which may restrict the Fund’s investment opportunities, including sanctions and restrictions on investing in issuers or industries deemed sensitive to relevant national interests and requirements that government approval be obtained prior to investment by foreign persons; (iv) certain national policies that may restrict the Fund’s repatriation of investment income, capital or the proceeds of sales of securities, including temporary restrictions on foreign capital remittances; (v) the lack of uniform accounting and auditing standards and/or standards that may be significantly different from the standards required in the United States; (vi) less publicly available financial and other information regarding issuers; (vii) potential difficulties in enforcing contractual obligations; and (viii) higher rates of inflation, higher interest rates and other economic concerns. The Fund may invest to a substantial extent in emerging market securities that are denominated in local currencies, subjecting the Fund to a greater degree of foreign currency risk. Also, investing in emerging market countries may entail purchases of securities of issuers that are insolvent, bankrupt or otherwise of

questionable ability to satisfy their payment obligations as they become due, subjecting the Fund to a greater amount of credit risk and/or high yield risk. The economy of some emerging markets may be particularly exposed to or affected by a certain industry or sector, and therefore issuers and/or securities of such emerging markets may be more affected by the performance of such industries or sectors.

Equity Securities and Related Market Risk

The market price of common stocks and other equity securities may go up or down, sometimes rapidly or unpredictably. Equity securities may decline in value due to factors affecting equity securities markets generally, particular industries represented in those markets, or the issuer itself. The values of equity securities may decline due to real or perceived adverse economic conditions, changes in the general outlook for corporate earnings, changes in interest or currency rates, adverse changes to credit markets or adverse investor sentiment generally. They may also decline due to labor shortages or increased production costs and competitive conditions within an industry. Equity securities generally have greater price volatility than bonds and other debt securities.

Different types of equity securities provide different voting and dividend rights and priority in the event of the bankruptcy and/or insolvency of the issuer. In addition to common stock, equity securities may include preferred securities, convertible securities and warrants. Equity securities other than common stock are subject to many of the same risks as common stock, although possibly to different degrees. The risks of equity securities are generally magnified in the case of equity investments in distressed companies.

Focused Investment Risk

To the extent that the Fund focuses its investments in a particular sector, it may be susceptible to loss due to adverse developments affecting that sector, including (but not limited to): governmental regulation; inflation; rising interest rates; cost increases in raw materials, fuel and other operating expenses; technological innovations that may render existing products and equipment obsolete; competition from new entrants; high research and development costs; increased costs associated with compliance with environmental or other governmental regulations; and other economic, business or political developments specific to that sector. Furthermore, the Fund may invest a substantial portion of its assets in companies in related sectors that may share common characteristics, are often subject to similar business risks and regulatory burdens, and whose securities may react similarly to the types of developments described above, which will subject the Fund to greater risk. The Fund also will be subject to focused investment risk to the extent that it invests a substantial portion of its assets in a particular issuer, market, asset class, country or geographic region.

Foreign (Non-U.S.) Investment Risk

Foreign (non-U.S.) securities may experience more rapid and extreme changes in value than securities of U.S. issuers or securities that trade exclusively in U.S. markets. The securities markets of many foreign countries are relatively small, with a limited number of companies representing a small number of industries. Additionally, issuers of foreign (non-U.S.) securities are usually not subject to the same degree of regulation as U.S. issuers. Reporting, accounting, auditing and custody standards of foreign countries differ, in some cases significantly, from U.S. standards. Global economies and financial markets are becoming increasingly interconnected, and conditions and events in one country, region or financial market may adversely impact issuers in a different country, region or financial market. Foreign (non-U.S.) market trading hours, clearance and settlement procedures, and holiday schedules may limit the Fund’s ability to buy and sell securities. Investments in foreign (non-U.S.) markets may also be adversely affected by governmental actions such as the imposition of capital controls, nationalization of companies or industries, expropriation of assets or the imposition of punitive taxes. The governments of certain countries may prohibit or impose substantial restrictions on foreign (non-U.S.) investing in their capital markets or in certain sectors or industries. In addition, a foreign (non-U.S.) government may limit or cause delay in the convertibility or repatriation of its currency which would adversely affect the U.S. dollar value and/or liquidity of investments denominated in that currency. Certain foreign (non-U.S.) investments may become less liquid in response to market developments or adverse investor perceptions, or become illiquid after purchase by the Fund, particularly during periods of market turmoil. A reduction in trading in securities of issuers located in countries whose economies are heavily dependent upon trading with key partners may have an adverse impact on a Fund’s investments.

Also, nationalization, expropriation or confiscatory taxation, unstable governments, decreased market liquidity, currency blockage, market disruptions, political changes, security suspensions or diplomatic developments or the imposition of sanctions or other similar measures could adversely affect the Fund’s investments in a foreign (non-U.S.) country. In the event of nationalization, expropriation or other confiscation, the Fund could lose its entire investment in foreign (non-U.S.) securities. The type and severity of sanctions and other similar measures, including counter sanctions and other retaliatory actions, that may be imposed could vary broadly in scope, and their impact is difficult to ascertain. These types of measures may include, but are not limited to, banning a sanctioned country or certain persons or entities associated with such country from global payment systems that facilitate cross-border payments, restricting the settlement of securities transactions by certain investors, and freezing the assets of

particular countries, entities or persons. The imposition of sanctions and other similar measures could, among other things, result in a decline in the value and/or liquidity of securities issued by the sanctioned country or companies located in or economically tied to the sanctioned country, downgrades in the credit ratings of the sanctioned country’s securities or those of companies located in or economically tied to the sanctioned country, currency devaluation or volatility, and increased market volatility and disruption in the sanctioned country and throughout the world. Sanctions and other similar measures could directly or indirectly limit or prevent a Fund from buying and selling securities (in the sanctioned country and other markets), significantly delay or prevent the settlement of securities transactions, and adversely impact a Fund’s liquidity and performance. Adverse conditions in a certain region can adversely affect securities of other countries whose economies appear to be unrelated. To the extent that the Fund invests a significant portion of its assets in a specific geographic region or in securities denominated in a particular foreign (non-U.S.) currency, the Fund will generally have more exposure to regional economic risks, including weather emergencies and natural disasters, associated with foreign (non-U.S.) investments. Foreign (non-U.S.) securities may also be less liquid (particularly during market closures due to local holidays or other reasons) and more difficult to value than securities of U.S. issuers.

The Fund may invest in securities and instruments that are economically tied to Russia. Investments in Russia are subject to various risks such as, but not limited to political, economic, legal, market and currency risks. The risks include uncertain political and economic policies, short term market volatility, poor accounting standards, corruption and crime, an inadequate regulatory system, regional armed conflict and unpredictable taxation. Investments in Russia are particularly subject to the risk that further economic sanctions, export and import controls, and other similar measures may be imposed by the United States and/or other countries. Other similar measures may include, but are not limited to, banning or expanding bans on Russia or certain persons or entities associated with Russia from global payment systems that facilitate cross-border payments, restricting the settlement of securities transactions by certain investors, and freezing Russian assets or those of particular countries, entities or persons with ties to Russia (e.g. Belarus). Such sanctions and other similar measures — which may impact companies in many sectors, including energy, financial services, technology, accounting, quantum computing, shipping, aviation, metals and mining, defense, architecture, engineering, construction, manufacturing and transportation, among others — and Russia’s countermeasures may negatively impact the Fund’s performance and/or ability to achieve its investment objectives. For example, certain investments may be prohibited and/or existing investments

may become illiquid (e.g., in the event that transacting in certain existing investments is prohibited, securities markets close, or market participants cease transacting in certain investments in light of geopolitical events, sanctions or related considerations), which could render any such securities held by the Fund unmarketable for an indefinite period of time and/or cause the Fund to sell portfolio holdings at a disadvantageous time or price or to continue to hold investments that the Fund no longer seeks to hold. In addition, such sanctions or other similar measures, and the Russian government’s response, could result in a downgrade of Russia’s credit rating or of securities of issuers located in or economically tied to Russia, devaluation of Russia’s currency and/or increased volatility with respect to Russian securities and the ruble. Moreover, disruptions caused by Russian military action or other actions (including cyberattacks, espionage or other asymmetric measures) or resulting actual or threatened responses to such activity may impact Russia’s economy and Russian and other issuers of securities in which the Fund is invested. Such resulting actual or threatened responses may include, but are not limited to, purchasing and financing restrictions, withdrawal of financial intermediaries, boycotts or changes in consumer or purchaser preferences, sanctions, export and import controls, tariffs or cyberattacks on the Russian government, Russian companies or Russian individuals, including politicians. Any actions by Russia made in response to such sanctions or retaliatory measures could further impair the value and liquidity of Fund investments. Sanctions and other similar measures have resulted in defaults on debt obligations by certain corporate issuers and the Russian Federation that could lead to cross-defaults or cross-accelerations on other obligations of these issuers.

The Russian securities market is characterized by limited volume of trading, resulting in difficulty in obtaining accurate prices and trading. These issues can be magnified as a result of sanctions and other similar measures that may be imposed and the Russian government’s response. The Russian securities market, as compared to U.S. markets, has significant price volatility, less liquidity, a smaller market capitalization and a smaller number of traded securities. There may be little publicly available information about issuers. Settlement, clearing and registration of securities transactions are subject to risks. Prior to the implementation of the National Settlement Depository (“NSD”), a recognized central securities depository, there was no central registration system for equity share registration in Russia, and registration was carried out by either the issuers themselves or by registrars located throughout Russia. Title to Russian equities held through the NSD is now based on the records of the NSD and not the registrars. Although the implementation of the NSD has enhanced the efficiency and transparency of the Russian securities market, issues resulting in loss can still occur. In addition, sanctions by the European

Union against the NSD, as well as the potential for sanctions by other governments, could make it more difficult to conduct or confirm transactions involving Russian securities. Ownership of securities issued by Russian companies that are not held through depositories such as the NSD may be recorded by companies themselves and by registrars. In such cases, the risk is increased that the Fund could lose ownership rights through fraud, negligence or oversight. While applicable Russian regulations impose liability on registrars for losses resulting from their errors, it may be difficult for the Fund to enforce any rights it may have against the registrar or issuer of the securities in the event of loss of share registration. In addition, issuers and registrars are still prominent in the validation and approval of documentation requirements for corporate action processing in Russia. Because the documentation requirements and approval criteria vary between registrars and issuers, there remain unclear and inconsistent market standards in the Russian market with respect to the completion and submission of corporate action elections. In addition, sanctions or Russian countermeasures may prohibit or limit a Fund’s ability to participate in corporate actions, and therefore require the Fund to forego voting on or receiving funds that would otherwise be beneficial to the Fund. To the extent that the Fund suffers a loss relating to title or corporate actions relating to its portfolio securities, it may be difficult for the Fund to enforce its rights or otherwise remedy the loss. Russian securities laws may not recognize foreign nominee accounts held with a custodian bank, and therefore the custodian may be considered the ultimate owner of securities they hold for their clients. Adverse currency exchange rates are a risk and there may be a lack of available currency hedging instruments. Investments in Russia may be subject to the risk of nationalization or expropriation of assets. Oil, natural gas, metals, minerals and timber account for a significant portion of Russia’s exports, leaving the country vulnerable to swings in world prices and to sanctions or other actions that may be directed at the Russian economy as a whole or at Russian oil, natural gas, metals, minerals or timber industries.

High Yield Securities Risk

To the extent that the Fund invests in high yield securities and unrated securities of similar credit quality (commonly known as “high yield securities” or “junk bonds”), the Fund may be subject to greater levels of credit risk, call risk and liquidity risk than funds that do not invest in such securities, which could have a negative effect on the NAV and market price of the Fund’s Common Shares or Common Share dividends. These securities are considered predominantly speculative with respect to an issuer’s continuing ability to make principal and interest payments, and may be more volatile than other types of securities. An economic downturn or individual corporate developments could adversely affect the market for these securities and reduce the Fund’s ability to sell these securities at an advantageous time or price. The Fund may purchase

distressed securities that are in default or the issuers of which are in bankruptcy, which involve heightened risks.

High yield securities structured as zero-coupon bonds or pay-in-kind securities tend to be especially volatile as they are particularly sensitive to downward pricing pressures from rising interest rates or widening spreads and may require the Fund to make taxable distributions of imputed income without receiving the actual cash currency. Issuers of high yield securities may have the right to “call” or redeem the issue prior to maturity, which may result in the Fund having to reinvest the proceeds in other high yield securities or similar instruments that may pay lower interest rates. The Fund may also be subject to greater levels of liquidity risk than funds that do not invest in high yield securities. Consequently, transactions in high yield securities may involve greater costs than transactions in more actively traded securities. A lack of publicly-available information, irregular trading activity and wide bid/ask spreads among other factors, may, in certain circumstances, make high yield debt more difficult to sell at an advantageous time or price than other types of securities or instruments. These factors may result in the Fund being unable to realize full value for these securities and/or may result in the Fund not receiving the proceeds from a sale of a high yield security for an extended period after such sale, each of which could result in losses to the Fund. Because of the risks involved in investing in high yield securities, an investment in the Fund should be considered speculative.

In general, lower rated debt securities carry a greater degree of risk that the issuer will lose its ability to make interest and principal payments, which could have a negative effect on the Fund. Securities of below investment grade quality are regarded as having predominantly speculative characteristics with respect to capacity to pay interest and repay principal and are commonly referred to as “high yield” securities or “junk bonds.” High yield securities involve a greater risk of default and their prices are generally more volatile and sensitive to actual or perceived negative developments. Debt securities in the lowest investment grade category also may be considered to possess some speculative characteristics by certain rating agencies. The Fund may purchase stressed or distressed securities that are in default or the issuers of which are in bankruptcy, which involve heightened risks.

An economic downturn could severely affect the ability of issuers (particularly those that are highly leveraged) to service or repay their debt obligations. Lower-rated securities are generally less liquid than higher-rated securities, which may have an adverse effect on the Fund’s ability to dispose of them. For example, under adverse market or economic conditions, the secondary market for below investment grade securities could contract further, independent of any specific adverse changes in the condition of a particular issuer, and certain

securities in the Fund’s portfolio may become illiquid or less liquid. As a result, the Fund could find it more difficult to sell these securities or may be able to sell these securities only at prices lower than if such securities were widely traded. To the extent the Fund focuses on below investment grade debt obligations, PIMCO’s capabilities in analyzing credit quality and associated risks will be particularly important, and there can be no assurance that PIMCO will be successful in this regard. Due to the risks involved in investing in high yield securities, an investment in the Fund should be considered speculative.

The Fund’s credit quality policies apply only at the time a security is purchased, and the Fund is not required to dispose of a security in the event that a rating agency or PIMCO downgrades its assessment of the credit characteristics of a particular issue. In determining whether to retain or sell such a security, PIMCO may consider factors including, but not limited to, PIMCO’s assessment of the credit quality of the issuer of such security, the price at which such security could be sold and the rating, if any, assigned to such security by other rating agencies. Analysis of creditworthiness may be more complex for issuers of high yield securities than for issuers of higher quality debt securities.

Inflation/Deflation Risk

Inflation risk is the risk that the value of assets or income from the Fund’s investments will be worth less in the future as inflation decreases the value of payments at future dates. As inflation increases, the real value of the Fund’s portfolio could decline. Inflation has increased and it cannot be predicted when, if, or the degree to which it may decline. Deflation risk is the risk that prices throughout the economy decline over time. Deflation may have an adverse effect on the creditworthiness of issuers and may make issuer default more likely, which may result in a decline in the value of the Fund’s portfolio and Common Shares.

Inflation-Indexed Security Risk

Inflation-indexed debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the value of an inflation-indexed security, including Treasury Inflation-Protected Securities (“TIPS”), tends to decrease when real interest rates increase and can increase when real interest rates decrease. Thus generally, during periods of rising inflation, the value of inflation-indexed securities will tend to increase and during periods of deflation, their value will tend to decrease. Interest payments on inflation-indexed securities are unpredictable and will fluctuate as the principal and interest are adjusted for inflation. There can be no assurance that the inflation index used (i.e., the Consumer Price Index (“CPI”)), which is calculated and published by a third-party, will accurately measure the real rate of inflation in the prices of goods and services. Increases in the principal value of TIPS

due to inflation are considered taxable ordinary income for the amount of the increase in the calendar year. Any increase in the principal amount of an inflation-indexed debt security will be considered taxable ordinary income, even though the Fund will not receive the principal until maturity. Additionally, a CPI swap can potentially lose value if the realized rate of inflation over the life of the swap is less than the fixed market implied inflation rate (fixed breakeven rate) that the investor agrees to pay at the initiation of the swap. With municipal inflation-indexed securities, the inflation adjustment is integrated into the coupon payment, which is federally tax exempt (and may be state tax exempt). For municipal inflation-indexed securities, there is no adjustment to the principal value. Because municipal inflation-indexed securities are a small component of the municipal bond market, they may be less liquid than conventional municipal bonds.

Interest Rate Risk

Interest rate risk is the risk that fixed income securities and other instruments in the Fund’s portfolio will fluctuate in value because of a change in interest rates. For example, as nominal interest rates rise, the value of certain fixed income securities held by the Fund is likely to decrease. A nominal interest rate can be described as the sum of a real interest rate and an expected inflation rate. Interest rate changes can be sudden and unpredictable, and the Fund may lose money as a result of movements in interest rates. The Fund may not be able to effectively hedge against changes in interest rates or may choose not to do so for cost or other reasons.

A wide variety of factors can cause interest rates or yields of U.S. Treasury securities (or yields of other types of bonds) to rise, including but not limited to central bank monetary policies, changing inflation or real growth rates, general economic conditions, increasing bond issuances or reduced market demand for low yielding investments. Risks associated with rising interest rates are heightened under current market conditions given that the U.S. Federal Reserve (the “Federal Reserve”) has raised interest rates from historically low levels. In addition, changes in monetary policy may exacerbate the risks associated with changing interest rates. Further, in market environments where interest rates are rising, issuers may be less willing or able to make principal and interest payments on fixed-income investments when due.

Further, fixed income securities with longer durations tend to be more sensitive to changes in interest rates, usually making them more volatile. Duration is a measure used to determine the sensitivity of a security’s price to changes in interest rates that incorporates a security’s yield, coupon, final maturity and call features, among other characteristics. Duration is useful primarily as a measure of the sensitivity of a fixed income security’s market price to interest rate (i.e., yield) movements. All other things remaining equal, for each one

percentage point increase in interest rates, the value of a portfolio of fixed income investments would generally be expected to decline by one percent for every year of the portfolio’s average duration above zero. For example, the value of a portfolio of fixed income securities with an average duration of eight years would generally be expected to decline by approximately 8% if interest rates rose by one percentage point.

Variable and floating rate securities may decline in value if their interest rates do not rise as much, or as quickly, as interest rates in general. Conversely, floating rate securities will not generally increase in value if interest rates decline. Inverse floating rate securities may decrease in value if interest rates increase. Inverse floating rate securities may also exhibit greater price volatility than a fixed rate obligation with similar credit quality. When the Fund holds variable or floating rate securities, a decrease (or, in the case of inverse floating rate securities, an increase) in market interest rates will adversely affect the income received from such securities and the NAV of the Fund’s shares.

During periods of very low or negative interest rates, the Fund may be unable to maintain positive returns. Very low or negative interest rates may magnify interest rate risk. Changing interest rates, including rates that fall below zero, may have unpredictable effects on markets, may result in heightened market volatility and may detract from Fund performance to the extent the Fund is exposed to such interest rates.

Measures such as average duration may not accurately reflect the true interest rate sensitivity of the Fund. This is especially the case if the Fund consists of securities with widely varying durations. Therefore, if the Fund has an average duration that suggests a certain level of interest rate risk, the Fund may in fact be subject to greater interest rate risk than the average would suggest. This risk is greater to the extent the Fund uses leverage or derivatives in connection with the management of the Fund.

Convexity is an additional measure used to understand a security’s or Fund’s interest rate sensitivity. Convexity measures the rate of change of duration in response to changes in interest rates. With respect to a security’s price, a larger convexity (positive or negative) may imply more dramatic price changes in response to changing interest rates. Convexity may be positive or negative. Negative convexity implies that interest rate increases result in increased duration, meaning increased sensitivity in prices in response to rising interest rates. Thus, securities with negative convexity, which may include bonds with traditional call features and certain mortgage-backed securities, may experience greater losses in periods of rising interest rates. Accordingly, if the Fund holds such securities, the Fund may be subject to a greater risk of losses in periods of rising interest rates.

Rising interest rates may result in a decline in value of the Fund’s fixed income investments and in periods of volatility. Also, when interest rates rise, issuers are less likely to refinance existing debt securities, causing the average life of such securities to extend. Further, while U.S. bond markets have steadily grown over the past three decades, dealer “market making” ability has remained relatively stagnant. As a result, dealer inventories of certain types of bonds and similar instruments, which provide a core indication of the ability of financial intermediaries to “make markets,” are at or near historic lows in relation to market size. Because market makers provide stability to a market through their intermediary services, a significant reduction in dealer inventories could potentially lead to decreased liquidity and increased volatility in the fixed income markets. Such issues may be exacerbated during periods of economic uncertainty. All of these factors, collectively and/or individually, could cause the Fund to lose value.

Issuer Risk

The value of a security may decline for a number of reasons that directly relate to the issuer, such as management performance, major litigation, investigations or other controversies, changes in financial condition or credit rating, changes in government regulations affecting the issuer or its competitive environment and strategic initiatives such as mergers, acquisitions or dispositions and the market response to any such initiatives, financial leverage or reduced demand for the issuer’s goods or services, as well as the historical and prospective earnings of the issuer and the value of its assets. A change in the financial condition of a single issuer may affect securities markets as a whole. These risks can apply to the Common Shares issued by the Fund and to the issuers of securities and other instruments in which the Fund invests.

Leverage Risk

The Fund’s use of leverage, if any, creates the opportunity for increased Common Share net income, but also creates special risks for Common Shareholders. To the extent used, there is no assurance that the Fund’s leveraging strategies will be successful. Leverage is a speculative technique that may expose the Fund to greater risk and increased costs. The Fund’s assets attributable to leverage, if any, will be invested in accordance with the Fund’s investment objectives and policies. Interest expense payable by the Fund with respect to derivatives and other forms of leverage, and dividends payable with respect to preferred shares outstanding, if any, will generally be based on shorter-term interest rates that would be periodically reset. So long as the Fund’s portfolio investments provide a higher rate of return (net of applicable Fund expenses) than the interest expenses and other costs to the Fund of such leverage, the investment of the proceeds thereof will generate more income than will be needed to pay the costs of the leverage. If so, and all other things being equal, the excess

may be used to pay higher dividends to Common Shareholders than if the Fund were not so leveraged. If, however, shorter-term interest rates rise relative to the rate of return on the Fund’s portfolio, the interest and other costs to the Fund of leverage could exceed the rate of return on the debt obligations and other investments held by the Fund, thereby reducing return to Common Shareholders. Leveraging transactions pursued by the Fund may increase its duration and sensitivity to interest rate movements. In addition, fees and expenses of any form of leverage used by the Fund will be borne entirely by the Common Shareholders (and not by preferred shareholders, if any) and will reduce the investment return of the Common Shares. Therefore, there can be no assurance that the Fund’s use of leverage will result in a higher yield on the Common Shares, and it may result in losses. In addition, any preferred shares issued by the Fund are expected to pay cumulative dividends, which may tend to increase leverage risk. Leverage creates several major types of risks for Common Shareholders, including:

∎  the likelihood of greater volatility of NAV and market price of Common Shares, and of the investment return to Common Shareholders, than a comparable portfolio without leverage;

∎  the possibility either that Common Share dividends will fall if the interest and other costs of leverage rise, or that dividends paid on Common Shares will fluctuate because such costs vary over time; and

∎  the effects of leverage in a declining market or a rising interest rate environment, as leverage is likely to cause a greater decline in the NAV of the Common Shares than if the Fund were not leveraged.

In addition, the counterparties to the Fund’s leveraging transactions and any preferred shareholders of the Fund will have priority of payment over the Fund’s Common Shareholders.

Reverse repurchase agreements involve the risks that the interest income earned on the investment of the proceeds will be less than the interest expense and Fund expenses associated with the repurchase agreement, that the market value of the securities sold by the Fund may decline below the price at which the Fund is obligated to repurchase such securities and that the securities may not be returned to the Fund. There is no assurance that reverse repurchase agreements can be successfully employed. Dollar roll transactions involve the risk that the market value of the securities the Fund is required to purchase may decline below the agreed upon repurchase price of those securities. Successful use of dollar rolls may depend upon the Investment Manager’s ability to correctly predict interest rates and prepayments. There is no assurance that dollar rolls can be successfully employed. In connection with reverse repurchase agreements and dollar rolls, the Fund will also be subject to counterparty risk with

respect to the purchaser of the securities. If the broker/dealer to whom the Fund sells securities becomes insolvent, the Fund’s right to purchase or repurchase securities may be restricted.

The Fund may engage in total return swaps, reverse repurchases, loans of portfolio securities, short sales and when-issued, delayed delivery and forward commitment transactions, credit default swaps, basis swaps and other swap agreements, purchases or sales of futures and forward contracts (including foreign currency exchange contracts), call and put options or other derivatives. The Fund’s use of such transactions gives rise to associated leverage risks described above, and may adversely affect the Fund’s income, distributions and total returns to Common Shareholders. To the extent that any offsetting positions do not behave in relation to one another as expected, the Fund may perform as if it is leveraged through use of these derivative strategies.

Any total return swaps, reverse repurchases, loans of portfolio securities, short sales and when-issued, delayed delivery and forward commitment transactions, credit default swaps, basis swaps and other swap agreements, purchases or sales of futures and forward contracts (including foreign currency exchange contracts), call and put options or other derivatives by the Fund or counterparties to the Fund’s other leveraging transactions, if any, would have seniority over the Fund’s Common Shares.

In addition to preferred shares, the Fund may engage in other transactions that may give rise to a form of leverage including, among others loans of portfolio securities, short sales and when-issued, delayed delivery and forward commitment transactions, credit default swaps, reverse repurchases, or other derivatives. The Fund’s use of such transactions gives rise to associated leverage risks described above, and may adversely affect the Fund’s income, distributions and total returns to Common Shareholders. The Fund may offset derivatives positions against one another or against other assets to manage effective market exposure resulting from derivatives in portfolio. To the extent that any offsetting positions do not behave in relation to one another as expected, the Fund may perform as if it is leveraged through use of these derivative strategies. See “Use of Leverage.”

The Fund is required to satisfy certain regulatory and rating agency asset coverage requirements in connection with its use of preferred shares. Accordingly, any decline in the net asset value of the Fund’s investments could result in the risk that the Fund will fail to meet its asset coverage requirements for any such preferred shares or the risk of the Preferred Shares being downgraded by a rating agency. In an extreme case, the Fund’s current investment income might not be sufficient to meet the dividend requirements on any preferred shares outstanding. In order to address these types of events, the Fund might

need to liquidate investments in order to fund a redemption of some or all of preferred shares. Liquidations at times of adverse economic conditions may result in a loss to the Fund. At other times, these liquidations may result in gain at the Fund level and thus in additional taxable distributions to Common Shareholders. See “Tax Matters” for more information. Any preferred shares of portfolio securities, short sales and when-issued, delayed delivery and forward commitment transactions, credit default swaps, reverse repurchases, or other derivatives by the Fund or counterparties to the Fund’s other leveraging transactions, if any, would have, seniority over the Fund’s Common Shares.

When the Fund issues preferred shares, the Fund pays (and the Common Shareholders bear) all costs and expenses relating to the issuance and ongoing maintenance of preferred shares. In addition, holders of any preferred shares issued by the Fund would have complete priority over Common Shareholders in the distribution of the Fund’s assets. Furthermore, preferred shareholders, voting separately as a single class, have the right to elect two members of the Board at all times and to elect a majority of the trustees in the event two full years’ dividends on the preferred shares are unpaid, and also have separate class voting rights on certain matters. Accordingly, preferred shareholders may have interests that differ from those of Common Shareholders, and may at times have disproportionate influence over the Fund’s affairs.

Because the fees received by the Investment Manager may increase depending on the types of leverage utilized by the Fund,1 the Investment Manager has a financial incentive for the Fund to use certain forms of leverage, which may create a conflict of interest between the Investment Manager, on the one hand, and the Common Shareholders, on the other hand.

Liquidity Risk

Liquidity risk exists when particular investments are difficult to purchase or sell. Illiquid investments are investments that the Fund reasonably expects cannot be sold or disposed of in current market conditions in seven calendar days or less without the sale or disposition significantly changing the market value of the investment. Illiquid investments may become harder to value, especially in changing markets. The Fund’s investments in illiquid investments may reduce the returns of the Fund because it may be unable to sell the illiquid investments at an advantageous time or price or possibly require the Fund to dispose of other investments at unfavorable times or prices in order to satisfy its obligations, which could prevent the Fund from taking advantage of other investment opportunities. Additionally, the market for certain investments may become illiquid under adverse market or economic conditions independent of any specific adverse changes in the conditions of a particular issuer. Bond

markets have consistently grown over the past three decades while the capacity for traditional dealer counterparties to engage in fixed income trading has not kept pace and in some cases has decreased. As a result, dealer inventories of corporate bonds, which provide a core indication of the ability of financial intermediaries to “make markets,” are at or near historic lows in relation to market size. Because market makers seek to provide stability to a market through their intermediary services, the significant reduction in dealer inventories could potentially lead to decreased liquidity and increased volatility in the fixed income markets. Such issues may be exacerbated during periods of economic uncertainty.

In such cases, the Fund, due to regulatory limitations on investments in illiquid investments and the difficulty in purchasing and selling such securities or instruments, may be unable to achieve its desired level of exposure to a certain sector. To the extent that the Fund’s principal investment strategies involve securities of companies with smaller market capitalizations, foreign (non-U.S.) securities, Rule 144A securities, illiquid sectors of fixed income securities, derivatives or securities with substantial market and/or credit risk, the Fund will tend to have the greatest exposure to liquidity risk.

Further, fixed income securities with longer durations until maturity face heightened levels of liquidity risk as compared to fixed income securities with shorter durations until maturity. The risks associated with illiquid instruments may be particularly acute in situations in which the Fund’s operations require cash (such as in connection with repurchase offers) and could result in the Fund borrowing to meet its short-term needs or incurring losses on the sale of illiquid instruments. It may also be the case that other market participants may be attempting to liquidate fixed income holdings at the same time as the Fund, causing increased supply in the market and contributing to liquidity risk and downward pricing pressure.

Liquidity risk also refers to the risk that the Fund may be required to hold additional cash or sell other investments in order to obtain cash to close out derivatives or meet the liquidity demands that derivatives can create to make payments of margin, collateral, or settlement payments to counterparties. The Fund may have to sell a security at a disadvantageous time or price to meet such obligations.

The current direction of governments and regulators may have the effect of reducing market liquidity, market resiliency and money supply, such as through higher rates, tighter financial regulations and proposals related to open-end fund liquidity that may prevent mutual funds and exchange-traded funds from participating in certain markets.

Loans and Other Indebtedness; Loan Participations and Assignments Risk

Loan interests may take the form of (i) direct interests acquired during a primary distribution or (ii) assignments of, novations of or participations in all or a portion of a loan acquired in secondary markets. In addition to credit risk and interest rate risk, the Fund’s exposure to loan interests may be subject to additional risks. For example, purchasers of loans and other forms of direct indebtedness depend primarily upon the creditworthiness of the borrower for payment of principal and interest. Loans are subject to the risk that scheduled interest or principal payments will not be made in a timely manner or at all, either of which may adversely affect the value of the loan. If the Fund does not receive scheduled interest or principal payments on such indebtedness, the Fund’s share price and yield could be adversely affected. Loans that are fully secured may offer the Fund more protection than an unsecured loan in the event of non-payment of scheduled interest or principal if the Fund is able to access and monetize the collateral. However, the collateral underlying a loan, if any, may be unavailable or insufficient to satisfy a borrower’s obligation. If the Fund becomes owner, whole or in part, of any collateral after a loan is foreclosed, the Fund may incur costs associated with owning and/or monetizing its ownership of the collateral.

Moreover, the purchaser of an assignment typically succeeds to all the rights and obligations under the loan agreement with the same rights and obligations as the assigning lender. Assignments may, however, be arranged through private negotiations between potential assignees and potential assignors, and the rights and obligations acquired by the purchaser of an assignment may differ from, and be more limited than, those held by the assigning lender.

Investments in loans through a purchase of a loan, loan origination or a direct assignment of a financial institution’s interests with respect to a loan may involve additional risks to the Fund. For example, if a loan is foreclosed, the Fund could become owner, in whole or in part, of any collateral, which could include, among other assets, real estate or other real or personal property, and would bear the costs and liabilities associated with owning and holding or disposing of the collateral. The purchaser of an assignment typically succeeds to all the rights and obligations under the loan agreement with the same rights and obligations as the assigning lender. Assignments may, however, be arranged through private negotiations between potential assignees and potential assignors, and the rights and obligations acquired by the purchaser of an assignment may differ from, and be more limited than, those held by the assigning lender.

In connection with purchasing loan participations, the Fund generally will have no right to enforce compliance by the borrower with the terms of the loan agreement relating to the loan, nor any rights of set-off against the borrower, and the Fund may not directly benefit from any collateral supporting the loan in which it has purchased the loan participation. As a result, the Fund will be subject to the credit risk of both the borrower and the lender that is selling the participation. In the event of the insolvency of the lender selling a participation, the Fund may be treated as a general creditor of the lender and may not benefit from any set-off between the lender and the borrower. Certain loan participations may be structured in a manner designed to prevent purchasers of participations from being subject to the credit risk of the lender, but even under such a structure, in the event of the lender’s insolvency, the lender’s servicing of the participation may be delayed and the assignability of the participation impaired.

The Fund may have difficulty disposing of loans and loan participations. Because there is no liquid market for many such investments, the Fund anticipates that such investments could be sold only to a limited number of institutional investors. The lack of a liquid secondary market may have an adverse impact on the value of such investments and the Fund’s ability to dispose of particular loans and loan participations when that would be desirable, including in response to a specific economic event such as a deterioration in the creditworthiness of the borrower. The lack of a liquid secondary market for loans and loan participations also may make it more difficult for the Fund to assign a value to these securities for purposes of valuing the Fund’s portfolio.

Investments in loans may include participations in bridge loans, which are loans taken out by borrowers for a short period (typically less than one year) pending arrangement of more permanent financing through, for example, the issuance of bonds, frequently high yield bonds issued for the purpose of acquisitions.

Investments in loans may include acquisitions of, or participation in, delayed funding loans and revolving credit facilities. These commitments may have the effect of requiring the Fund to increase its investment in a borrower at a time when it might not otherwise decide to do so (including at a time when the company’s financial condition makes it unlikely that such amounts will be repaid). Delayed funding loans and revolving credit facilities may be subject to restrictions on transfer, and only limited opportunities may exist to resell such instruments. As a result, a Fund may be unable to sell such investments at an opportune time or may have to resell them at less than fair market value. Further, the Fund may need to hold liquid assets in order to provide funding for these types of commitments, meaning the Fund may not be able to invest in other

attractive investments, or the Fund may need to liquidate existing assets in order to provide such funding.

To the extent the Fund invests in loans, including bank loans, the Fund may be subject to greater levels of credit risk, call risk, settlement risk and liquidity risk. These instruments are considered predominantly speculative with respect to an issuer’s continuing ability to make principal and interest payments and may be more volatile than other types of securities. The Fund may also be subject to greater levels of liquidity risk than funds that do not invest in loans. In addition, the loans in which the Fund invests may not be listed on any exchange and a secondary market for such loans may be comparatively illiquid relative to markets for other more liquid fixed income securities. Consequently, transactions in loans may involve greater costs than transactions in more actively traded securities. In connection with certain loan transactions, transaction costs that are borne by the Fund may include the expenses of third parties that are retained to assist with reviewing and conducting diligence, negotiating, structuring and servicing a loan transaction, and/or providing other services in connection therewith. Furthermore, the Fund may incur such costs in connection with loan transactions that are pursued by the Fund but not ultimately consummated (so-called “broken deal costs”).

Restrictions on transfers in loan agreements, a lack of publicly available information, irregular trading activity and wide bid/ask spreads, among other factors, may, in certain circumstances, make loans more difficult to sell at an advantageous time or price than other types of securities or instruments. These factors may result in the Fund being unable to realize full value for the loans and/or may result in the Fund not receiving the proceeds from a sale of a loan for an extended period after such sale, each of which could result in losses to the Fund. Some loans may have extended trade settlement periods, including settlement periods of greater than seven days, which may result in cash not being immediately available to the Fund. If an issuer of a loan prepays or redeems the loan prior to maturity, the Fund may have to reinvest the proceeds in other loans or similar instruments that may pay lower interest rates. Because of the risks involved in investing in loans, an investment in the Fund should be considered speculative.

The Fund’s investments in subordinated and unsecured loans generally are subject to similar risks as those associated with investments in secured loans. Subordinated or unsecured loans are lower in priority of payment to secured loans and are subject to the additional risk that the cash flow of the borrower and property securing the loan or debt, if any, may be insufficient to meet scheduled payments after giving effect to the senior secured obligations of the borrower. This risk is generally higher for subordinated unsecured loans or debt, which are not backed by a security interest in any specific collateral. Subordinated and unsecured loans generally have greater price

volatility than secured loans and may be less liquid. There is also a possibility that originators will not be able to sell participations in subordinated or unsecured loans, which would create greater credit risk exposure for the holders of such loans. Subordinate and unsecured loans share the same risks as other below investment grade securities.

There may be less readily available information about most loans and the underlying borrowers than is the case for many other types of securities. Loans may be issued by borrowers that are not subject to SEC reporting requirements and therefore may not be required to file reports with the SEC or may file reports that are not required to comply with SEC form requirements. In addition, such borrowers may be subject to a less stringent liability disclosure regime than companies subject to SEC reporting requirements. Loans may not be considered “securities,” and purchasers, such as the Fund, therefore may not be entitled to rely on the anti-fraud protections of the federal securities laws. Because there is limited public information available regarding loan investments, the Fund is particularly dependent on the analytical abilities of the Fund’s portfolio managers.

Economic exposure to loan interests through the use of derivative transactions may involve greater risks than if the Fund had invested in the loan interest directly during a primary distribution or through assignments of, novations of or participations in a loan acquired in secondary markets since, in addition to the risks described above, certain derivative transactions may be subject to leverage risk and greater illiquidity risk, counterparty risk, valuation risk and other risks.

Management Risk

The Fund is subject to management risk because it is an actively managed investment portfolio. PIMCO and each individual portfolio manager will apply investment techniques and risk analysis in making investment decisions for the Fund, but there can be no guarantee that these decisions will produce the desired results. Certain securities or other instruments in which the Fund seeks to invest may not be available in the quantities desired. In addition, regulatory restrictions, actual or potential conflicts of interest or other considerations may cause PIMCO to restrict or prohibit participation in certain investments. In such circumstances, PIMCO or the individual portfolio managers may determine to purchase other securities or instruments as substitutes. Such substitute securities or instruments may not perform as intended, which could result in losses to the Fund. To the extent the Fund employs strategies targeting perceived pricing inefficiencies, arbitrage strategies or similar strategies, it is subject to the risk that the pricing or valuation of the securities and instruments involved in such strategies may change unexpectedly, which may result in reduced returns or losses to the Fund. Additionally, actual or potential conflicts of interest, legislative, regulatory, or tax restrictions, policies or developments may affect the investment techniques

available to PIMCO and each individual portfolio manager in connection with managing the Fund and may also adversely affect the ability of the Fund to achieve its investment objectives. There also can be no assurance that all of the personnel of PIMCO will continue to be associated with PIMCO for any length of time. The loss of services of one or more key employees of PIMCO could have an adverse impact on the Fund’s ability to realize its investment objectives.

In addition, the Fund may rely on various third-party sources to calculate its NAV. As a result, the Fund is subject to certain operational risks associated with reliance on service providers and service providers’ data sources. In particular, errors or systems failures and other technological issues may adversely impact the Fund’s calculations of its NAV, and such NAV calculation issues may result in inaccurately calculated NAVs, delays in NAV calculation and/or the inability to calculate NAVs over extended periods. The Fund may be unable to recover any losses associated with such failures.

Market Discount Risk

The price of the Fund’s Common Shares will fluctuate with market conditions and other factors. If you sell your Common Shares, the price received may be more or less than your original investment. The Common Shares are designed for long-term investors and should not be treated as trading vehicles. Shares of closed-end management investment companies frequently trade at a discount from their NAV.

Market Disruptions Risk

The Fund is subject to investment and operational risks associated with financial, economic and other global market developments and disruptions, including those arising from war, terrorism, market manipulation, government interventions, defaults and shutdowns, political changes or diplomatic developments, public health emergencies (such as the spread of infectious diseases, pandemics and epidemics) and natural/environmental disasters, which can all negatively impact the securities markets, interest rates, auctions, secondary trading, ratings, credit risk, inflation, deflation, other factors relating to the Fund’s investments or the Investment Manager’s operations and the value of an investment in the Fund, its distributions and its returns. These events can also impair the technology and other operational systems upon which the Fund’s service providers, including PIMCO as the Fund’s investment adviser, rely, and could otherwise disrupt the Fund’s service providers’ ability to fulfill their obligations to the Fund. Furthermore, events involving limited liquidity, defaults, non-performance or other adverse developments that affect financial institutions or the financial services industry generally, or concerns or rumors about any events of these kinds or other similar risks, have in the past and may in the future lead to market-wide liquidity problems.

Market Risk

The market price of securities owned by the Fund may go up or down, sometimes rapidly or unpredictably. Securities may decline in value due to factors affecting securities markets generally or particular industries or issuers represented in the securities markets. The value of a security may decline due to general market conditions that are not specifically related to a particular company, such as real or perceived adverse economic conditions, changes in the general outlook for corporate earnings, changes in interest or currency rates, adverse changes to credit markets or adverse investor sentiment generally. The value of a security may also decline due to factors that affect a particular industry or industries, such as labor shortages or increased production costs and competitive conditions within an industry. During a general downturn in the securities markets, multiple asset classes may decline in value simultaneously. Equity securities generally have greater price volatility than fixed income securities. Credit ratings downgrades may also negatively affect securities held by the Fund. Even when markets perform well, there is no assurance that the investments held by the Fund will increase in value along with the broader market.

In addition, market risk includes the risk that geopolitical and other events will disrupt the economy on a national or global level. For instance, war, terrorism, social unrest, recessions, supply chain disruptions, market manipulation, government defaults, government shutdowns, political changes, diplomatic developments or the imposition of sanctions and other similar measures, public health emergencies (such as the spread of infectious diseases, pandemics and epidemics) and natural/environmental disasters can all negatively impact the securities markets, which could cause the Fund to lose value. These events could reduce consumer demand or economic output, result in market closures, changes in interest rates, inflation/deflation, travel restrictions or quarantines, and significantly adversely impact the economy. The current contentious domestic political environment, as well as political and diplomatic events within the United States and abroad, such as presidential elections in the U.S. or abroad or the U.S. government’s inability at times to agree on a long-term budget and deficit reduction plan, has in the past resulted, and may in the future result, in a government shutdown or otherwise adversely affect the U.S. regulatory landscape, the general market environment and/or investor sentiment, which could have an adverse impact on the Fund’s investments and operations. Additional and/or prolonged U.S. federal government shutdowns may affect investor and consumer confidence and may adversely impact financial markets and the broader economy, perhaps suddenly and to a significant degree. Governmental and quasi-governmental authorities and regulators throughout the world have previously responded to serious economic disruptions with a variety of significant fiscal and monetary policy changes, including but not limited to, direct capital infusions into

companies, new monetary programs and dramatically lower interest rates. An unexpected or sudden reversal of these policies, or the ineffectiveness of these policies, could increase volatility in securities markets, which could adversely affect the Fund’s investments. Any market disruptions could also prevent the Fund from executing advantageous investment decisions in a timely manner. Funds that have focused their investments in a region enduring geopolitical market disruption will face higher risks of loss. Thus, investors should closely monitor current market conditions to determine whether the Fund meets their individual financial needs and tolerance for risk.

Recently, there have been inflationary price movements. As such, fixed income securities markets may experience heightened levels of interest rate, volatility and liquidity risk. As discussed more under “Interest Rate Risk,” the Federal Reserve has begun to raise interest rates from historically low levels and has signaled an intention to continue to do so. Any additional interest rate increases in the future could cause the value of any Fund, such as the Fund, that invests in fixed income securities to decrease.

Although interest rates have significantly increased since 2022 through the date of this report, the prices of real estate-related assets generally have not decreased as much as may be expected based on historical correlations between interest rates and prices of real estate-related assets. This presents an increased risk of a correction or severe downturn in real estate-related asset prices, which could adversely impact the value of other investments as well (such as loans, securitized debt and other fixed income securities). This risk is particularly present with respect to commercial real estate-related asset prices, and the value of other investments with a connection to the commercial real estate sector. As examples of the current risks faced by real estate-related assets: tenant vacancy rates, tenant turnover and tenant concentration have increased; owners of real estate have faced headwinds, delinquencies and difficulties in collecting rents and other payments (which increases the risk of owners being unable to pay or otherwise defaulting on their own borrowings and obligations); property values have declined; inflation, upkeep costs and other expenses have increased; and rents have declined for many properties.

Exchanges and securities markets may close early, close late or issue trading halts on specific securities, which may result in, among other things, the Fund being unable to buy or sell certain securities or financial instruments at an advantageous time or accurately price its portfolio investments.

Mortgage-Related and Other Asset-Backed Instruments Risk

The mortgage-related assets in which the Fund may invest include, but are not limited to, any security, instrument or other asset that is

related to U.S. or non-U.S. mortgages, including those issued by private originators or issuers, or issued or guaranteed as to principal or interest by the U.S. government or its agencies or instrumentalities or by non-U.S. governments or authorities, such as, without limitation, assets representing interests in, collateralized or backed by, or whose values are determined in whole or in part by reference to any number of mortgages or pools of mortgages or the payment experience of such mortgages or pools of mortgages, including REMICs, which could include Re-REMICs, mortgage pass-through securities, inverse floaters, CMOs, CLOs, multiclass pass-through securities, private mortgage pass-through securities, stripped mortgage securities (generally interest-only and principal-only securities), mortgage-related asset backed securities and mortgage-related loans (including through participations, assignments, originations and whole loans), including commercial and residential mortgage loans. Exposures to mortgage-related assets through derivatives or other financial instruments will be considered investments in mortgage-related assets.

The Fund may also invest in other types of ABS, including CDOs, CBOs and CLOs and other similarly structured securities.

Mortgage-related and other asset-backed instruments represent interests in “pools” of mortgages or other assets such as consumer loans or receivables held in trust and often involve risks that are different from or possibly more acute than risks associated with other types of debt instruments. Generally, rising interest rates tend to extend the duration of fixed rate mortgage-related assets, making them more sensitive to changes in interest rates. Compared to other fixed income investments with similar maturity and credit, mortgage-related securities may increase in value to a lesser extent when interest rates decline and may decline in value to a similar or greater extent when interest rates rise. As a result, in a period of rising interest rates, the Fund may exhibit additional volatility since individual mortgage holders are less likely to exercise prepayment options, thereby putting additional downward pressure on the value of these securities and potentially causing the Fund to lose money. This is known as extension risk. Mortgage-backed securities can be highly sensitive to rising interest rates, such that even small movements can cause the Fund to lose value. Mortgage-backed securities, and in particular those not backed by a government guarantee, are subject to credit risk. When interest rates decline, borrowers may pay off their mortgages sooner than expected. This can reduce the returns of the Fund because the Fund may have to reinvest that money at the lower prevailing interest rates. The Fund’s investments in other asset-backed instruments are subject to risks similar to those associated with mortgage-related assets, as well as additional risks associated with the nature of the assets and the servicing of those assets. Payment of principal and

interest on asset-backed instruments may be largely dependent upon the cash flows generated by the assets backing the instruments, and asset-backed instruments may not have the benefit of any security interest in the related assets.

Subordinate mortgage-backed or asset-backed instruments are paid interest only to the extent that there are funds available to make payments. To the extent the collateral pool includes a large percentage of delinquent loans, there is a risk that interest payments on subordinate mortgage-backed or asset-backed instruments will not be fully paid.

There are multiple tranches of mortgage-backed and asset-backed instruments, offering investors various maturity and credit risk characteristics. Tranches are categorized as senior, mezzanine, and subordinated/equity or “first loss,” according to their degree of risk. The most senior tranche of a mortgage-backed or asset-backed instrument has the greatest collateralization and pays the lowest interest rate. If there are defaults or the collateral otherwise underperforms, scheduled payments to senior tranches take precedence over those of mezzanine tranches, and scheduled payments to mezzanine tranches take precedence over those to subordinated/equity tranches. Lower tranches represent lower degrees of credit quality and pay higher interest rates intended to compensate for the attendant risks. The return on the lower tranches is especially sensitive to the rate of defaults in the collateral pool. The lowest tranche (i.e., the “equity” or “residual” tranche) specifically receives the residual interest payments (i.e., money that is left over after the higher tranches have been paid and expenses of the issuing entities have been paid) rather than a fixed interest rate. The Fund may also invest in the residual or equity tranches of mortgage-related and other asset-backed instruments, which may be referred to as subordinate mortgage-backed or asset-backed instruments and interest-only mortgage-backed or asset-backed instruments. The Fund expects that investments in subordinate mortgage-backed and other asset-backed instruments will be subject to risks arising from delinquencies and foreclosures, thereby exposing its investment portfolio to potential losses. The Fund expects that investments in the lowest tranche of or subordinate mortgage-backed and other asset-backed instruments will be subject to the greatest risks of losing part or all of their values, which could arise from delinquencies and foreclosures, thereby exposing the Fund’s investment portfolio to potential losses. Subordinate securities of mortgage-backed and other asset-backed instruments are also subject to greater credit risk than those mortgage-backed or other asset-backed instruments that are more highly rated.

The mortgage markets in the United States and in various foreign countries have experienced extreme difficulties in the past that

adversely affected the performance and market value of certain of the Fund’s mortgage-related investments. Delinquencies and losses on residential and commercial mortgage loans (especially subprime and second-lien mortgage loans) may increase, and a decline in or flattening of housing and other real property values may exacerbate such delinquencies and losses. In addition, reduced investor demand for mortgage loans and mortgage-related securities and increased investor yield requirements have caused limited liquidity in the secondary market for mortgage-related securities, which can adversely affect the market value of mortgage-related securities. It is possible that such limited liquidity in such secondary markets could continue or worsen.

With respect to risk retention tranches (i.e., eligible residual interests initially held by the sponsors of CMBS and other eligible securitizations pursuant to the U.S. Risk Retention Rules), a third-party purchaser, such as the Fund, must hold its retained interest, unhedged, for at least five year following the closing of the CMBS transaction, after which it is entitled to transfer its interest in the securitization to another person that meets the requirements for a third-party purchaser. Even after the required holding period has expired, due to the generally illiquid nature of such investments, no assurance can be given as to what, if any, exit strategies will ultimately be available for any given position.

In addition, there is limited guidance on the application of the Final U.S. Risk Retention Rules to specific securitization structures. There can be no assurance that the applicable federal agencies charged with the implementation of the Final U.S. Risk Retention Rules (the FDIC, the Comptroller of the Currency, the Federal Reserve Board, the SEC, the Department of Housing and Urban Development, and the Federal Housing Finance Agency) could not take positions in the future that differ from the interpretation of such rules taken or embodied in such securitizations, or that the Final U.S. Risk Retention Rules will not change.

Furthermore, in situations where the Fund invests in risk retention tranches of securitizations structured by third parties, the Fund may be required to execute one or more letters or other agreements, the exact form and nature of which will vary (each, a “Risk Retention Agreement”) under which it will make certain undertakings designed to ensure such securitization complies with the U.S. Risk Retention Rules. Such Risk Retention Agreements may include a variety of representations, warranties, covenants and other indemnities, each of which may run to various transaction parties. If the Fund breaches any undertakings in any Risk Retention Agreement, it will be exposed to claims by the other parties thereto, including for any losses incurred as a result of such breach, which could be significant and exceed the value of the Fund’s investments.

Mortgage-Related Derivative Instruments Risk

The Fund may engage in derivative transactions related to mortgage-backed securities, including purchasing and selling exchange-listed and OTC put and call options, futures and forwards on mortgages and mortgage-backed securities. The Fund may also invest in mortgage-backed securities credit default swaps, which include swaps the reference obligation for which is a mortgage-backed security or related index, such as the CMBX Index (a tradeable index referencing a basket of commercial mortgage-backed securities), the TRX Index (a tradeable index referencing total return swaps based on commercial mortgage-backed securities) or the ABX (a tradeable index referencing a basket of sub-prime mortgage-backed securities). The Fund may invest in newly developed mortgage related derivatives that may hereafter become available.

Derivative mortgage-backed securities (such as principal-only (“POs”), interest-only (“IOs”) or inverse floating rate securities) are particularly exposed to call and extension risks. Small changes in mortgage prepayments can significantly impact the cash flows and the market value of these derivative instruments. In general, the risk of faster than anticipated prepayments adversely affects IOs, super floaters and premium priced mortgage-backed securities. The risk of slower than anticipated prepayments generally affects POs, floating-rate securities subject to interest rate caps, support tranches and discount priced mortgage-backed securities. In addition, particular derivative instruments may be leveraged such that their exposure (i.e., price sensitivity) to interest rate and/or prepayment risk is magnified.

Mortgage-related derivative instruments involve risks associated with mortgage-related and other asset-backed instruments, privately-issued mortgage-related securities, the mortgage market, the real estate industry, derivatives and credit default swaps.

Operational Risk

An investment in the Fund, like any fund, can involve operational risks arising from factors such as processing errors, human errors, inadequate or failed internal or external processes, failures in systems and technology, changes in personnel and errors caused by third-party service providers. The occurrence of any of these failures, errors or breaches could result in a loss of information, regulatory scrutiny, reputational damage or other events, any of which could have a material adverse effect on the Fund. While the Fund seeks to minimize such events through controls and oversight, there may still be failures that could cause losses to the Fund.

Other Investment Companies Risk

When investing in an investment company, the Fund will generally bear its ratable share of that investment company’s expenses and would remain subject to payment of the Fund’s management fees and other expenses with respect to assets so invested. Common Shareholders

would therefore be subject to duplicative expenses to the extent the Fund invests in other investment companies. In addition, the securities of other investment companies may also be leveraged and will therefore be subject to same leverage risks.

Platform Risk

The Alt Lending ABS in which the Fund may invest are typically not listed on any securities exchange and not registered under the Securities Act. In addition, the Fund anticipates that these instruments may only be sold to a limited number of investors and may have a limited or non-existent secondary market. Accordingly, the Fund currently expects that certain of the investments it may make in Alt Lending ABS will face heightened levels of liquidity risk. Although currently there is generally no reliable, active secondary market for certain Alt Lending ABS, a secondary market for these Alt Lending ABS may develop. If the Fund purchases Alt Lending ABS on an alternative lending platform, the Fund will have the right to receive principal and interest payments due on loans underlying the Alt Lending ABS only if the platform servicing the loans receives the borrower’s payments on such loans and passes such payments through to the Fund. If a borrower is unable or fails to make payments on a loan for any reason, the Fund may be greatly limited in its ability to recover any outstanding principal or interest due, as (among other reasons) the Fund may not have direct recourse against the borrower or may otherwise be limited in its ability to directly enforce its rights under the loan, whether through the borrower or the platform through which such loan was originated, the loan may be unsecured or under-collateralized and/or it may be impracticable to commence a legal proceeding against the defaulting borrower.

The Fund may have limited knowledge about the underlying loans and is dependent upon the platform for information regarding underlying loans. Although PIMCO may conduct diligence on the platforms, the Fund generally does not have the ability to independently verify the information provided by the platforms, other than payment information regarding loans underlying the Alt Lending ABS owned by the Fund, which the Fund observes directly as payments are received. With respect to Alt Lending ABS that the Fund purchases in the secondary market (i.e., not directly from an alternative lending platform), the Fund may not perform the same level of diligence on such platform or at all. The Fund may not review the particular characteristics of the loans collateralizing an Alt Lending ABS, but rather negotiate in advance with platforms the general criteria of the underlying loans. As a result, the Fund is dependent on the platforms’ ability to collect, verify and provide information to the Fund about each loan and borrower.

The Fund relies on the borrower’s credit information, which is provided by the platforms. However, such information may be out of date,

incomplete or inaccurate and may, therefore, not accurately reflect the borrower’s actual creditworthiness. Platforms may not have an obligation to update borrower information, and, therefore, the Fund may not be aware of any impairment in a borrower’s creditworthiness subsequent to the making of a particular loan. The platforms’ credit decisions and scoring models may be based on algorithms that could potentially contain programming or other errors or prove to be ineffective or otherwise flawed. This could adversely affect loan pricing data and approval processes and could cause loans to be mispriced or misclassified, which could ultimately have a negative impact on the Fund’s performance.

In addition, the underlying loans, in some cases, may be affected by the success of the platforms through which they are facilitated.

Therefore, disruptions in the businesses of such platforms may also negatively impact the value of the Fund’s investments. In addition, disruption in the business of a platform could limit or eliminate the ability of the Fund to invest in loans originated by that platform, and therefore the Fund could lose some or all of the benefit of its diligence effort with respect to that platform.

Platforms are for-profit businesses that, as a general matter, generate revenue by collecting fees on funded loans from borrowers and by assessing a loan servicing fee on investors, which may be a fixed annual amount or a percentage of the loan or amounts collected. This business could be disrupted in multiple ways; for example, a platform could file for bankruptcy or a platform might suffer reputational harm from negative publicity about the platform or alternative lending more generally and the loss of investor confidence in the event that a loan facilitated through the platform is not repaid and the investor loses money on its investment. Many platforms and/or their affiliates have incurred operating losses since their inception and may continue to incur net losses in the future, particularly as their businesses grow and they incur additional operating expenses. Platforms may also be forced to defend legal action taken by regulators or governmental bodies. Alternative lending is a newer industry operating in an evolving legal environment. Platforms may be subject to risk of litigation alleging violations of law and/or regulations, including, for example, consumer protection laws, whether in the U.S. or in foreign jurisdictions. Platforms may be unsuccessful in defending against such lawsuits or other actions and, in addition to the costs incurred in fighting any such actions, platforms may be required to pay money in connection with the judgments, settlements or fines or may be forced to modify the terms of its borrower loans, which could cause the platform to realize a loss or receive a lower return on a loan than originally anticipated. Platforms may also be parties to litigation or other legal action in an attempt to protect or enforce their rights or those of affiliates, including intellectual property rights, and may incur similar costs in

connection with any such efforts. The Fund’s investments in Alt Lending ABS may expose the Fund to the credit risk of the issuer. Generally, such instruments are unsecured obligations of the issuer; an issuer that becomes subject to bankruptcy proceedings may be unable to make full and timely payments on its obligations to the Fund, even if the payments on the underlying loan or loans continue to be made timely and in full. In addition, when the Fund owns Alt Lending ABS, the Fund and its custodian generally does not have a contractual relationship with, or personally identifiable information regarding, individual borrowers, so the Fund will not be able to enforce underlying loans directly against borrowers and may not be able to appoint an alternative servicing agent in the event that a platform or third-party servicer, as applicable, ceases to service the underlying loans. Therefore, the Fund is more dependent on the platform for servicing than if the Fund had owned whole loans through the platform. Where such interests are secured, the Fund relies on the platform to perfect the Fund’s security interest. In addition, there may be a delay between the time the Fund commits to purchase an instrument issued by a platform, its affiliate or a special purpose entity sponsored by the platform or its affiliate and the issuance of such instrument and, during such delay, the funds committed to such an investment will not earn interest on the investment nor will they be available for investment in other alternative lending-related instruments, which will reduce the effective rate of return on the investment. The Fund’s investments in Alt Lending ABS may be illiquid.

Portfolio Turnover Risk

The Investment Manager manages the Fund without regard generally to restrictions on portfolio turnover. The use of futures contracts and other derivative instruments with relatively short maturities may tend to exaggerate the portfolio turnover rate for the Fund. Trading in fixed income securities does not generally involve the payment of brokerage commissions but does involve indirect transaction costs. The use of futures contracts and other derivative instruments may involve the payment of commissions to futures commission merchants or other intermediaries. Higher portfolio turnover involves correspondingly greater expenses to the Fund, including brokerage commissions or dealer mark-ups and other transaction costs on the sale of securities and reinvestments in other securities. The higher the rate of portfolio turnover of the Fund, the higher these transaction costs borne by the Fund generally will be. Such sales may result in realization of taxable capital gains (including short-term capital gains, which are generally taxed to shareholders at ordinary income tax rates when distributed net of short-term capital losses and net long-term capital losses) and may adversely impact the Fund’s after-tax returns.

Potential Conflicts of Interest Risk — Allocation of Investment Opportunities

The Investment Manager and its affiliates are involved worldwide with a broad spectrum of financial services and asset management activities and may engage in the ordinary course of business in activities in which their interests or the interests of their clients may conflict with those of the Fund. The Investment Manager may provide investment management services to other funds and discretionary managed accounts that follow an investment program similar to that of the Fund. Subject to the requirements of the 1940 Act, the Investment Manager intends to engage in such activities and may receive compensation from third parties for its services. The results of the Fund’s investment activities may differ from those of the Fund’s affiliates, or another account managed by the Investment Manager or its affiliates, and it is possible that the Fund could sustain losses during periods in which one or more of the Fund’s affiliates and/or other accounts managed by the Investment Manager or its affiliates, including proprietary accounts, achieve profits on their trading.

Preferred Securities Risk

In addition to equity securities risk, credit risk and possibly high yield risk, investment in preferred securities involves certain other risks. Certain preferred securities contain provisions that allow an issuer under certain conditions to skip or defer distributions. If the Fund owns a preferred security that is deferring its distribution, the Fund may be required to include the amount of the deferred distribution in its taxable income for tax purposes although it does not currently receive such amount in cash. In order to receive the special treatment accorded to regulated investment companies and their shareholders under the Internal Revenue Code of 1986, as amended (the “Code”) and to avoid U.S. federal income and/or excise taxes at the Fund level, the Fund may be required to distribute this income to shareholders in the tax year in which the income is recognized (without a corresponding receipt of cash). Therefore, the Fund may be required to pay out as an income distribution in any such tax year an amount greater than the total amount of cash income the Fund actually received and to sell portfolio securities, including at potentially disadvantageous times or prices, to obtain cash needed for these income distributions. Preferred securities often are subject to legal provisions that allow for redemption in the event of certain tax or legal changes or at the issuer’s call. In the event of redemption, the Fund may not be able to reinvest the proceeds at comparable rates of return. Preferred securities are subordinated to bonds and other debt securities in an issuer’s capital structure in terms of priority for corporate income and liquidation payments, and therefore will be subject to greater credit risk than those debt securities. Preferred securities may trade less frequently and in a more limited volume and may be subject to more abrupt or erratic price movements than many other securities.

Additional Risks Associated with the Fund’s Preferred Shares

Although the Fund’s ARPS ordinarily would pay dividends at rates set at periodic auctions, the weekly auctions for the ARPS (and auctions for similar preferred shares issued by closed-end funds in the U.S.) have failed since 2008. The dividend rates on the ARPS since that time have been paid, and the Fund expects that they will continue to be paid for the foreseeable future, at the “maximum applicable rate” under the Fund’s Bylaws (i.e., the greater of a multiple of or a spread plus a reference rate). An increase in market interest rates generally, therefore, could increase substantially the dividend rate required to be paid by the Fund to the holders of ARPS, which would increase the costs associated with the Fund’s leverage and reduce the Fund’s net income available for distribution to Common Shareholders. In addition, the multiple or spread used to calculate the maximum applicable rate is based in part on the credit rating assigned to the ARPS by the applicable rating agency(ies), with the multiple or spread generally increasing as the rating declines. The Fund’s ARPS rating has previously been downgraded and the ARPS could be subject to further ratings downgrades in the future, possibly resulting in further increases to the maximum applicable rate.

Therefore, it is possible that a substantial rise in market interest rates and/or further ratings downgrades of the ARPS could, by reducing income available for distribution to the Common Shareholders and otherwise detracting from the Fund’s investment performance, make the Fund’s continued use of Preferred Shares for leverage purposes less attractive than such use is currently considered to be. In such case, the Fund may elect to redeem some or all of the Preferred Shares outstanding, which may require it to dispose of investments at inopportune times and to incur losses on such dispositions. Such dispositions may adversely affect the Fund’s investment performance generally, and the resultant loss of leverage may materially and adversely affect the Fund’s investment returns to Common Shareholders. The Fund has previously been required to redeem a portion of its ARPS due to market dislocations that caused the value of the Fund’s portfolio securities and related asset coverage to decline and could be required to do so again in the future.

The Fund is also subject to certain asset coverage tests associated with the rating agencies that rate the ARPS. Failure by the Fund to maintain the asset coverages (or to cure such failure in a timely manner) may require the Fund to redeem ARPS. Failure to satisfy ratings agency asset coverage tests or other guidelines could also result in the applicable ratings agency downgrading its then-current ratings on the ARPS, as described above. Moreover, the rating agency guidelines impose restrictions or limitations on the Fund’s use of certain financial instruments or investment techniques that the Fund might otherwise utilize in order to achieve its investment objective, which may adversely affect the Fund’s investment performance. Rating agency

guidelines may be modified by the rating agencies in the future and such modifications may make such guidelines substantially more restrictive or otherwise result in downgrades, which could further negatively affect the Fund’s investment performance.

As discussed further in “Notes to Financial Statements — Auction-Rate Preferred Shares”, on December 4, 2020, Fitch published revised ratings criteria relating to closed-end fund obligations, including preferred shares, which effectively result in a rating cap of “A” for the Fund. Following the close of business on April 30, 2021, Fitch downgraded its rating of the Fund’s ARPS from “AA” to “A” pursuant to the revised ratings methodology and related new rating caps. With respect to PIMCO Corporate & Income Strategy Fund, under the Fund’s Bylaws, the April 2021 Fitch downgrade resulted in an increase in the multiple used to calculate the maximum applicable rate from 150% to 160%, thereby increasing the dividend rate payable to the Fund’s ARPS holders and increasing the expenses to the Common Shareholders associated with the Fund’s leverage. In December 2022, Moody’s downgraded its rating of the PCN ARPS, PFL ARPS and PFN ARPs from “Aa3” to “A1,” stating that the downgrades occurred because of, among other matters, trends in each respective Fund’s risk-adjusted asset coverage metrics and the evolution of its sector exposures. With respect to each of PIMCO Income Strategy Fund and PIMCO Income Strategy Fund II, under each Fund’s Bylaws, the April 2021 Fitch downgrade resulted in an increase in the dividend rate multiplier from 1.50 to 2.00, which could increase the dividend rate payable to each Fund’s ARPS holders should the maximum dividend rate be determined via the multiplier in lieu of the spread noted above (the maximum dividend rate is based on the greater of a multiple of or a spread plus a reference rate) and, thereby, increase the expenses to Common Shareholders associated with the Fund’s leverage.

Privacy and Data Security Risk

The Gramm-Leach-Bliley Act (“GLBA”) and other laws limit the disclosure of certain non-public personal information about a consumer to non- affiliated third parties and require financial institutions to disclose certain privacy policies and practices with respect to information sharing with both affiliates and non- affiliated third parties. Many states and a number of non-U.S. jurisdictions have enacted privacy and data security laws requiring safeguards on the privacy and security of consumers’ personally identifiable information. Other laws deal with obligations to safeguard and dispose of private information in a manner designed to avoid its dissemination. Privacy rules adopted by the U.S. Federal Trade Commission and SEC implement GLBA and other requirements and govern the disclosure of consumer financial information by certain financial institutions, ranging from banks to private investment funds. U.S. platforms following certain models generally are required to have privacy policies that conform to these GLBA and other requirements. In addition, such

platforms typically have policies and procedures intended to maintain platform participants’ personal information securely and dispose of it properly.

The Fund generally does not intend to obtain or hold borrowers’ non-public personal information, and the Fund has implemented procedures designed to prevent the disclosure of borrowers’ non-public personal information to the Fund. However, service providers to the Fund, or its direct or indirect fully-owned subsidiaries, including their custodians and the platforms acting as loan servicers for the Fund or its direct or indirect fully-owned subsidiaries, may obtain, hold or process such information. The Fund cannot guarantee the security of non-public personal information in the possession of such a service provider and cannot guarantee that service providers have been and will continue to comply with the GLBA, other data security and privacy laws and any other related regulatory requirements. Violations of the GLBA and other laws could subject the Fund to litigation and/or fines, penalties or other regulatory action, which, individually or in the aggregate, could have an adverse effect on the Fund. The Fund may also face regulations related to privacy and data security in the other jurisdictions in which the Fund invests.

Private Placements and Restricted Securities Risk

A private placement involves the sale of securities that have not been registered under the 1933 Act, or relevant provisions of applicable non-U.S. law, to certain institutional and qualified individual purchasers, such as the Fund. In addition to the general risks to which all securities are subject, securities received in a private placement generally are subject to strict restrictions on resale, and there may be no liquid secondary market or ready purchaser for such securities. Therefore, the Fund may be unable to dispose of such securities when it desires to do so, or at the most favorable time or price. Private placements may also raise valuation risks.

Restricted securities are often purchased at a discount from the market price of unrestricted securities of the same issuer reflecting the fact that such securities may not be readily marketable without some time delay. Such securities are often more difficult to value and the sale of such securities often requires more time and results in higher brokerage charges or dealer discounts and other selling expenses than does the sale of securities trading on national securities exchanges or in the over-the-counter markets. Until the Fund can sell such securities into the public markets, its holdings may be less liquid and any sales will need to be made pursuant to an exemption under the Securities Act.

Privately Issued Mortgage-Related Securities Risk

There are no direct or indirect government or agency guarantees of payments in pools created by non-governmental issuers. Privately-issued mortgage-related securities are also not subject to the same

underwriting requirements for the underlying mortgages that are applicable to those mortgage-related securities that have a government or government-sponsored entity guarantee.

Privately-issued mortgage-related securities are not traded on an exchange and there may be a limited market for the securities, especially when there is a perceived weakness in the mortgage and real estate market sectors. Without an active trading market, mortgage-related securities held in the Fund’s portfolio may be particularly difficult to value because of the complexities involved in assessing the value of the underlying mortgage loans.

Real Estate Risk

To the extent that the Fund invests in real estate investments, including investments in equity or debt securities issued by private and public REITs, real estate operating companies (“REOCs”), private or public real estate-related loans and real estate-linked derivative instruments, it will be subject to the risks associated with owning real estate and with the real estate industry generally. These risks include, but are not limited to: the burdens of ownership of real property; general and local economic conditions (such as an oversupply of space or a reduction in demand for space); the supply and demand for properties (including competition based on rental rates); energy and supply shortages; fluctuations in average occupancy and room rates; the attractiveness, type and location of the properties and changes in the relative popularity of commercial properties as an investment; the financial condition and resources of tenants, buyers and sellers of properties; increased mortgage defaults; the quality of maintenance, insurance and management services; changes in the availability of debt financing which may render the sale or refinancing of properties difficult or impracticable; changes in building, environmental and other laws and/or regulations (including those governing usage and improvements), fiscal policies and zoning laws; changes in real property tax rates; changes in interest rates and the availability of mortgage funds which may render the sale or refinancing of properties difficult or impracticable; changes in operating costs and expenses; energy and supply shortages; uninsured losses or delays from casualties or condemnation; negative developments in the economy that depress travel or leasing activity; environmental liabilities; contingent liabilities on disposition of assets; uninsured or uninsurable casualties; acts of God, including earthquakes, hurricanes and other natural disasters; social unrest and civil disturbances, epidemics, pandemics or other public crises; terrorist attacks and war; risks and operating problems arising out of the presence of certain construction materials, structural or property level latent defects, work stoppages, shortages of labor, strikes, union relations and contracts, fluctuating prices and supply of labor and/or other labor-related factor; and other factors which are beyond the control of PIMCO and its affiliates.

In addition, the Fund’s investments will be subject to various risks which could cause fluctuations in occupancy, rental rates, operating income and expenses or which could render the sale or financing of its properties difficult or unattractive. For example, following the termination or expiration of a tenant’s lease, there may be a period of time before receiving rental payments under a replacement lease. During that period, the Fund would continue to bear fixed expenses such as interest, real estate taxes, maintenance and other operating expenses. In addition, declining economic conditions may impair the ability to attract replacement tenants and achieve rental rates equal to or greater than the rents paid under previous leases. Increased competition for tenants may require capital improvements to properties which would not have otherwise been planned.

Ultimately, to the extent it is not possible to renew leases or re-let space as leases expire, decreased cash flow from tenants will result, which could adversely impact the Fund’s operating results.

Real estate values have historically been cyclical. As the general economy grows, demand for real estate increases and occupancies and rents may increase. As occupancies and rents increase, property values increase, and new development occurs. As development may occur, occupancies, rents and property values may decline. Because leases are usually entered into for long periods and development activities often require extended times to complete, the real estate value cycle often lags the general business cycle. Because of this cycle, real estate companies may incur large swings in their profits and the prices of their securities. Developments following the onset of COVID-19 have adversely impacted certain commercial real estate markets, causing the deferral of mortgage payments, renegotiated commercial mortgage loans, commercial real estate vacancies or outright mortgage defaults, and potential acceleration of macro trends such as work from home and online shopping which may negatively impact certain industries, such as brick-and-mortar retail.

The total returns available from investments in real estate generally depend on the amount of income and capital appreciation generated by the related properties. The performance of real estate, and thereby the Fund, will be reduced by any related expenses, such as expenses paid directly at the property level and other expenses that are capitalized or otherwise embedded into the cost basis of the real estate.

Separately, certain service providers to the Fund and/or its subsidiaries, as applicable, with respect to its real state or real estate-related investments are expected to be, or are owned by, employed by, or otherwise related to, PIMCO, Allianz SE, their affiliates and/or their respective employees, consultants and other personnel. PIMCO may, in its sole discretion, determine to provide, or engage or recommend an

affiliate of PIMCO to provide, certain services to the Fund, instead of engaging or recommending one or more third parties to provide such services. Subject to the governance requirements of a particular fund and applicable law, PIMCO or its affiliates, as applicable, will receive compensation in connection with the provision of such services. As a result, PIMCO faces a conflict of interest when selecting or recommending service providers for the Fund. Fees paid to an affiliated service provider will be determined in PIMCO’s commercially reasonable discretion. Although PIMCO has adopted various policies and procedures intended to mitigate or otherwise manage conflicts of interest with respect to affiliated service providers, there can be no guarantee that such policies and procedures (which may be modified or terminated at any time in PIMCO’s sole discretion) will be successful.

Regulation S Securities Risk

Regulation S securities are offered through off-shore (non-U.S.) offerings without registration with the SEC pursuant to Regulation S of the Securities Act. Because Regulation S securities are subject to legal or contractual restrictions on resale, Regulation S securities may be considered illiquid. Furthermore, because Regulation S securities are generally less liquid than registered securities, a Fund may take longer to liquidate these positions than would be the case for publicly traded securities. Although Regulation S securities may be resold in privately negotiated transactions, the price realized from these sales could be less than off-shore transactions or in those originally paid by the Fund. Further, companies whose securities are not publicly traded may not be subject to the disclosure and other investor protection requirements that would be applicable if their securities were publicly traded. Accordingly, Regulation S securities may involve a high degree of business and financial risk and may result in substantial losses.

Regulatory Changes Risk

Financial entities, such as investment companies and investment advisers, are generally subject to extensive government regulation and intervention. Government regulation and/or intervention may change the way the Fund is regulated, affect the expenses incurred directly by the Fund and the value of its investments, and limit and /or preclude the Fund’s ability to achieve its investment objective. Government regulation may change frequently and may have significant adverse consequences. The Fund and the Investment Manager have historically been eligible for exemptions from certain regulations. However, there is no assurance that the Fund and the Investment Manager will continue to be eligible for such exemptions. Actions by governmental entities may also impact certain instruments in which the Fund invests.

Moreover, government regulation may have unpredictable and unintended effects. Legislative or regulatory actions to address

perceived liquidity or other issues in fixed income markets generally, or in particular markets such as the municipal securities market, may alter or impair the Fund’s ability to pursue its investment objectives or utilize certain investment strategies and techniques.

Regulatory Risk — Commodity Pool Operator

The CFTC has adopted regulations that subject registered investment companies and their investment advisers to regulation by the CFTC if the registered investment company invests more than a prescribed level of its liquidation value in futures, options on futures or commodities, swaps, or other financial instruments regulated under the CEA and the rules thereunder (“commodity interests”), or if the Fund markets itself as providing investment exposure to such instruments. The Investment Manager is registered with the CFTC as a CPO. However, with respect to the Fund, the Investment Manager has claimed an exclusion from registration as a CPO pursuant to CFTC Rule 4.5. For the Investment Manager to remain eligible for this exclusion, the Fund must comply with certain limitations, including limits on its ability to use any commodity interests and limits on the manner in which the Fund holds out its use of such commodity interests. These limitations may restrict the Fund’s ability to pursue its investment objectives and strategies, increase the costs of implementing its strategies, result in higher expenses for the Fund, and/or adversely affect the Fund’s total return. To the extent the Fund becomes ineligible for this exclusion from CFTC regulation, the Fund may consider steps in order to continue to qualify for exemption from CFTC regulation, or may determine to operate subject to CFTC regulation.

Regulatory Risk — LIBOR

Certain instruments in which the Fund may invest have relied or continue in some fashion upon the London Interbank Offered Rate (“LIBOR”). LIBOR was traditionally an average interest rate, determined by the ICE Benchmark Administration, that banks charge one another for the use of short-term money. On March 5, 2021, the Financial Conduct Authority (“FCA”), the United Kingdom’s financial regulatory body and regulator of LIBOR, publicly announced that all U.S. Dollar LIBOR settings will either cease to be provided by any administrator or will no longer be representative (i) immediately after December 31, 2021 for one-week and two-month U.S. Dollar LIBOR settings and (ii) immediately after June 30, 2023 for the remaining U.S. Dollar LIBOR settings. As of January 1, 2022, as a result of supervisory guidance from U.S. regulators, U.S. regulated entities have generally ceased entering into new LIBOR contracts with limited exceptions. Publication of all Japanese yen and the one- and six-month sterling LIBOR settings have ceased, and while publication of the three-month Sterling LIBOR setting will continue through at least the end of March 2024 on the basis of a changed methodology (known as “synthetic LIBOR”), this rate has been designated by the FCA as unrepresentative of the underlying market that it seeks to

measure and is solely available for use in legacy transactions. Certain bank-sponsored committees in other jurisdictions, including Europe, the United Kingdom, Japan and Switzerland, have selected alternative reference rates denominated in other currencies. Although the transition process away from LIBOR for many instruments has been completed, some LIBOR use is continuing and there are potential effects related to the transition away from LIBOR or continued use of LIBOR on the Fund, or on certain instruments in which the Fund invests, which can be difficult to ascertain, and may vary depending on factors that include, but are not limited to: (i) existing fallback or termination provisions in individual contracts and (ii) whether, how, and when industry participants adopt new reference rates for affected instruments. So-called “tough legacy” contracts have LIBOR interest rate provisions with no fallback provisions contemplating a permanent discontinuation of LIBOR, inadequate fallback provisions or fallback provisions which may not effectively result in a transition away from LIBOR prior to LIBOR’s planned replacement date. On March 15, 2022, the Adjustable Interest Rate (LIBOR) Act was signed into law. This law provides a statutory fallback mechanism on a nationwide basis to replace LIBOR with a benchmark rate that is selected by the Board of Governors of the Federal Reserve System based on the Secured Overnight Financing Rate (“SOFR”) for tough legacy contracts. On February 27, 2023, the Federal Reserve System’s final rule in connection with this law became effective, establishing benchmark replacements based on SOFR and Term SOFR (a forward-looking measurement of market expectations of SOFR implied from certain derivatives markets) for applicable tough legacy contracts governed by U.S. law. In addition, the FCA has announced that it will require the publication of synthetic LIBOR for the one-month, three-month and six-month U.S. Dollar LIBOR settings after June 30, 2023 through at least September 30, 2024. Certain of the Fund’s investments may involve individual tough legacy contracts which may be subject to the Adjustable Interest Rate (LIBOR) Act or synthetic LIBOR and no assurances can be given that these measures will have had the intended effects. Moreover, certain aspects of the transition from LIBOR have relied or will continue to rely on the actions of third-party market participants, such as clearing houses, trustees, administrative agents, asset servicers and certain service providers; PIMCO cannot guarantee the performance of such market participants and any failure on the part of such market participants to manage their part of the LIBOR transition could impact the Fund. The transition of investments from LIBOR to a replacement rate as a result of amendment, application of existing fallbacks, statutory requirements or otherwise may also result in a reduction in the value of certain instruments held by the Fund or a reduction in the effectiveness of related Fund transactions such as hedges. In addition, an instrument’s transition to a replacement rate could result in variations in the reported yields of the Fund that holds such instrument. Any such

effects of the transition away from LIBOR, as well as other unforeseen effects, could result in losses to the Fund.

Reinvestment Risk

Income from the Fund’s portfolio will decline if and when the Fund invests the proceeds from matured, traded or called debt obligations at market interest rates that are below the portfolio’s current earnings rate. For instance, during periods of declining interest rates, an issuer of debt obligations may exercise an option to redeem securities prior to maturity, forcing the Fund to invest in lower-yielding securities. The Fund also may choose to sell higher yielding portfolio securities and to purchase lower yielding securities to achieve greater portfolio diversification, because the portfolio managers believe the current holdings are overvalued or for other investment-related reasons. A decline in income received by the Fund from its investments is likely to have a negative effect on dividend levels and the market price, NAV and/or overall return of the Common Shares.

REIT Risk

REITs are pooled investment vehicles that own, and usually operate, income-producing real estate. Some REITs also finance real estate. If a REIT meets certain requirements, including distributing to shareholders substantially all of its taxable income (other than net capital gains), then it is not typically taxed on the income distributed to shareholders. Therefore, REITs may pay higher dividends than other issuers.

REITs can be divided into three basic types: Equity REITs, Mortgage REITs and Hybrid REITs. Equity REITs invest the majority of their assets directly in real property. They derive their income primarily from rents received and any profits on the sale of their properties. Mortgage REITs invest the majority of their assets in real estate mortgages and derive most of their income from mortgage interest payments. As its name suggests, Hybrid REITs combine characteristics of both Equity REITs and Mortgage REITs.

An investment in a REIT, or in a real estate linked derivative instrument linked to the value of a REIT, is subject to the risks that impact the value of the underlying properties of the REIT. These risks include loss to casualty or condemnation, and changes in supply and demand, interest rates, zoning laws, regulatory limitations on rents, property taxes and operating expenses. Other factors that may adversely affect REITs include poor performance by management of the REIT, changes to the tax laws, or failure by the REIT to qualify for favorable tax treatment. The securities of REITs involve greater risks than those associated with larger, more established companies and may be subject to more abrupt or erratic price movements because of interest rate changes, economic conditions and other factors. For example, the value of these securities may decline when interest rates rise and will also be affected by the real estate market and by the

management or development of the underlying properties. The underlying properties may be subject to mortgage loans, which may also be subject to the risks of default. REITs are also subject to default by borrowers and self-liquidation, and are heavily dependent on cash flow. Some REITs lack diversification because they invest in a limited number of properties, a narrow geographic area, or a single type of property. Mortgage REITs may be impacted by the quality of the credit extended.

Repurchase Agreements Risk

The Fund may enter into repurchase agreements, in which the Fund purchases a security from a bank or broker-dealer, which agrees to repurchase the security at the Fund’s cost plus interest within a specified time. If the party agreeing to repurchase should default, the Fund would seek to sell the securities which it holds. This could involve procedural costs or delays in addition to a loss on the securities if their value should fall below their repurchase price. Repurchase agreements may be or become illiquid. These events could also trigger adverse tax consequences for the Fund.

Risk Retention Investment Risk

The Fund may invest in risk retention tranches of commercial mortgage-backed securities (“CMBS”) or other eligible securitizations, if any (“risk retention tranches”), which are eligible residual interests held by the sponsors of such securitizations pursuant to the final rules implementing the credit risk retention requirements of Section 941 of the Dodd-Frank Act (the “U.S. Risk Retention Rules”). In the case of CMBS transactions, for example, the U.S. Risk Retention Rules permit all or a portion of the retained credit risk associated with certain securitizations (i.e., retained risk) to be held by an unaffiliated “third party purchaser,” such as the Fund, if, among other requirements, the third-party purchaser holds its retained interest, unhedged, for at least five years following the closing of the CMBS transaction, after which it is entitled to transfer its interest in the securitization to another person that meets the requirements for a third-party purchaser. Even after the required holding period has expired, due to the generally illiquid nature of such investments, no assurance can be given as to what, if any, exit strategies will ultimately be available for any given position.

In addition, there is limited guidance on the application of the final U.S. Risk Retention Rules to specific securitization structures. There can be no assurance that the applicable federal agencies charged with the implementation of the final U.S. Risk Retention Rules (the Federal Deposit Insurance Corporation, the Comptroller of the Currency, the Federal Reserve Board, the SEC, the Department of Housing and Urban Development, and the Federal Housing Finance Agency) could not take positions in the future that differ from the interpretation of such rules taken or embodied in such securitizations, or that the final U.S. Risk Retention Rules will not change.

Furthermore, in situations where the Fund invests in risk retention tranches of securitizations structured by third parties, the Fund may be required to execute one or more letters or other agreements, the exact form and nature of which will vary (each, a “Risk Retention Agreement”) under which it will make certain undertakings designed to ensure such securitization complies with the U.S. Risk Retention Rules. Such Risk Retention Agreements may include a variety of representations, warranties, covenants and other indemnities, each of which may run to various transaction parties. If the Fund breaches any undertakings in any Risk Retention Agreement, it will be exposed to claims by the other parties thereto, including for any losses incurred as a result of such breach, which could be significant and exceed the value of the Fund’s investments.

Securities Lending Risk

For the purpose of achieving income, the Fund may lend its portfolio securities to brokers, dealers, and other financial institutions provided a number of conditions are satisfied, including that the loan is fully collateralized. When the Fund lends portfolio securities, its investment performance will continue to reflect changes in the value of the securities loaned, and the Fund will also receive a fee or interest on the collateral. Securities lending involves the risk of loss of rights in the collateral or delay in recovery of the collateral if the borrower fails to return the security loaned or becomes insolvent. The Fund may pay lending fees to a party arranging the loan. Cash collateral received by the Fund in securities lending transactions may be invested in short-term liquid fixed income instruments or in money market or short-term mutual funds, or similar investment vehicles, including affiliated money market or short-term mutual funds. The Fund bears the risk of such investments.

Senior Debt Risk

The Fund may be subject to greater levels of credit risk than funds that do not invest in below investment grade senior debt. The Fund may also be subject to greater levels of liquidity risk than funds that do not invest in senior debt. Restrictions on transfers in loan agreements, a lack of publicly available information and other factors may, in certain instances, make senior debt more difficult to sell at an advantageous time or price than other types of securities or instruments. Additionally, if the issuer of senior debt prepays, the Fund will have to consider reinvesting the proceeds in other senior debt or similar instruments that may pay lower interest rates.

Short Exposure Risk

The Fund’s short sales and short positions, if any, are subject to special risks. A short sale involves the sale by the Fund of a security that it does not own with the hope of purchasing the same security at a later date at a lower price. The Fund may also enter into a short position through a forward commitment or a short derivative position

through a futures contract or swap agreement. If the price of the security or derivative has increased during this time, then the Fund will incur a loss equal to the increase in price from the time that the short sale was entered into plus any transaction costs (i.e., premiums and interest) paid to the broker-dealer to borrow securities. Therefore, short sales involve the risk that losses may be exaggerated, potentially losing more money than the actual cost of the investment. By contrast, a loss on a long position arises from decreases in the value of the security and is limited by the fact that a security’s value cannot decrease below zero.

By investing the proceeds received from selling securities short, the Fund could be deemed to be employing a form of leverage, which creates special risks. The use of leverage may increase the Fund’s exposure to long security positions and make any change in the Fund’s NAV greater than it would be without the use of leverage. This could result in increased volatility of returns. There is no guarantee that any leveraging strategy the Fund employs will be successful during any period in which it is employed.

In times of unusual or adverse market, economic, regulatory or political conditions, the Fund may not be able, fully or partially, to implement its short selling strategy. Periods of unusual or adverse market, economic, regulatory or political conditions generally may exist for long periods of time. Also, there is the risk that the third party to the short sale or short position will not fulfill its contractual obligations, causing a loss to the Fund.

Special Purpose Acquisition Companies (“SPACs”) Risk

The Fund may invest in securities of SPACs or similar special purpose entities that pool funds to seek potential acquisition opportunities. Unless and until an acquisition is completed, a SPAC generally invests its assets (less a portion retained to cover expenses) in US government securities, money market securities or holds cash; if an acquisition that meets the requirements for the SPAC is not completed within a pre-established period of time, the invested funds are returned to the entity’s shareholders unless shareholders approve alternative options. Because SPACs and similar entities are in essence blank check companies without operating history or ongoing business other than seeking acquisitions, the value of their securities is particularly dependent on the ability of the entity’s management to identify and complete a profitable acquisition. A SPAC’s structure may result in significant dilution of a stockholder’s share value immediately upon the completion of a business combination due to, among other reasons, interests held by the SPAC sponsor, conversion of warrants into additional shares, shares issued in connection with a business combination and/or certain embedded costs. There is no guarantee that the SPACs in which the Fund invests will complete an acquisition or that any acquisitions that are completed will be profitable. Some

SPACs may pursue acquisitions only within certain industries or regions, which may increase the volatility of their prices. In addition, these securities, which are typically traded in the over-the-counter market, may be considered illiquid and/or be subject to restrictions on resale.

Smaller Company Risk

The general risks associated with debt instruments or equity securities are particularly pronounced for securities issued by companies with small market capitalizations. Small capitalization companies involve certain special risks. They are more likely than larger companies to have limited product lines, markets or financial resources, or to depend on a small, inexperienced management group. Securities of smaller companies may trade less frequently and in lesser volume than more widely held securities and their values may fluctuate more sharply than other securities. They may also have limited liquidity. These securities may therefore be more vulnerable to adverse developments than securities of larger companies, and the Fund may have difficulty purchasing or selling securities positions in smaller companies at prevailing market prices. Also, there may be less publicly available information about smaller companies or less market interest in their securities as compared to larger companies. Companies with medium-sized market capitalizations may have risks similar to those of smaller companies.

Sovereign Debt Risk

In addition to the other risks applicable to debt investments, sovereign debt may decline in value as a result of default or other adverse credit event resulting from an issuer’s inability or unwillingness to make principal or interest payments in a timely fashion. A sovereign entity’s failure to make timely payments on its debt can result from many factors, including, without limitation, insufficient foreign (non-U.S.) currency reserves or an inability to sufficiently manage fluctuations in relative currency valuations, an inability or unwillingness to satisfy the demands of creditors and/or relevant supranational entities regarding debt service or economic reforms, the size of the debt burden relative to economic output and tax revenues, cash flow difficulties, and other political and social considerations. The risk of loss to the Fund in the event of a sovereign debt default or other adverse credit event is heightened by the unlikelihood of any formal recourse or means to enforce its rights as a holder of the sovereign debt. In addition, sovereign debt restructurings, which may be shaped by entities and factors beyond the Fund’s control, may result in a loss in value of the Fund’s sovereign debt holdings.

Structured Investments Risk

Holders of structured products, including structured notes, credit-linked notes and other types of structured products, bear the risks of the underlying investments, index or reference obligation and are

subject to counterparty risk. The Fund may have the right to receive payments only from the structured product, and generally does not have direct rights against the issuer or the entity that sold the assets to be securitized. While certain structured products enable the investor to acquire interests in a pool of securities without the brokerage and other expenses associated with directly holding the same securities, investors in structured products generally pay their share of the structured product’s administrative and other expenses. Although it is difficult to predict whether the prices of indices and securities underlying structured products will rise or fall, these prices (and, therefore, the prices of structured products) are generally influenced by the same types of political and economic events that affect issuers of securities and capital markets generally. If the issuer of a structured product uses shorter term financing to purchase longer term securities, the issuer may be forced to sell its securities at below market prices if it experiences difficulty in obtaining such financing, which may adversely affect the value of the structured products owned by the Fund. Structured products generally entail risks associated with derivative instruments.

Subprime Risk

Loans, and debt instruments collateralized by loans (including Alt Lending ABS), acquired by the Fund may be subprime in quality, or may become subprime in quality. Although there is no specific legal or market definition of “subprime,” subprime loans are generally understood to refer to loans made to borrowers that display poor credit histories and other characteristics that correlate with a higher default risk. Accordingly, subprime loans, and debt instruments secured by such loans (including Alt Lending ABS), have speculative characteristics and are subject to heightened risks, including the risk of nonpayment of interest or repayment of principal, and the risks associated with investments in high yield securities. In addition, these instruments could be subject to increased regulatory scrutiny. The Fund is not restricted by any particular borrower credit risk criteria and/or qualifications when acquiring loans or debt instruments collateralized by loans.

Subsidiary Risk

To the extent the Fund invests through one or more of its subsidiaries, the Fund would be exposed to the risks associated with such subsidiary’s investments. Such subsidiaries would likely not be registered as investment companies under the 1940 Act and therefore would not be subject to all of the investor protections of the 1940 Act. Changes in the laws of the United States and/or the jurisdiction in which a subsidiary is organized could result in the inability of the Fund and/or the subsidiary to operate as intended and could adversely affect the Fund.

Synthetic Convertible Securities Risk

Synthetic convertible securities involve the combination of separate securities that possess the two principal characteristics of a traditional convertible security (i.e., an income-producing component and a right to acquire an equity security). Synthetic convertible securities are often achieved, in part, through investments in warrants or options to buy common stock (or options on a stock index), and therefore are subject to the risks associated with derivatives. The value of a synthetic convertible security will respond differently to market fluctuations than a traditional convertible security because a synthetic convertible is composed of two or more separate securities or instruments, each with its own market value. Because the convertible component is typically achieved by investing in warrants or options to buy common stock at a certain exercise price, or options on a stock index, synthetic convertible securities are subject to the risks associated with derivatives. In addition, if the value of the underlying common stock or the level of the index involved in the convertible component falls below the exercise price of the warrant or option, the warrant or option may lose all value.

Tax Risk

The Fund has elected to be treated as a “regulated investment company” (a “RIC”) under the Code and intends each year to qualify and be eligible to be treated as such, so that it generally will not be subject to U.S. federal income tax on its net investment income or net short-term or long-term capital gains, that are distributed (or deemed distributed, as described below) to shareholders. In order to qualify and be eligible for such treatment, the Fund must meet certain asset diversification tests, derive at least 90% of its gross income for such year from certain types of qualifying income, and distribute to its shareholders at least 90% of its “investment company taxable income” as that term is defined in the Code (which includes, among other things, dividends, taxable interest and the excess of any net short-term capital gains over net long-term capital losses, as reduced by certain deductible expenses).

The Fund’s investment strategy will potentially be limited by its intention to continue qualifying for treatment as a RIC, and can limit the Fund’s ability to continue qualifying as such. The tax treatment of certain of the Fund’s investments under one or more of the qualification or distribution tests applicable to regulated investment companies is uncertain. An adverse determination or future guidance by the IRS or a change in law might affect the Fund’s ability to qualify or be eligible for treatment as a RIC. Income and gains from certain of a Fund’s activities may not constitute qualifying income to a RIC for purposes of the 90% gross income test. If a Fund were to treat income or gain from a particular investment or activity as qualifying income and the income or gain were later determined not to constitute qualifying income and, together with any other nonqualifying income,

caused the Fund’s nonqualifying income to exceed 10% of its gross income in any taxable year, the Fund would fail to qualify as a RIC unless it is eligible to and does pay a tax at the Fund level.

If, in any year, the Fund were to fail to qualify for treatment as a RIC under the Code and were ineligible to or did not otherwise cure such failure, the Fund would be subject to tax on its taxable income at corporate rates and, when such income is distributed, shareholders would be subject to further tax on such distributions to the extent of the Fund’s current or accumulated earnings and profits.

U.S. Government Securities Risk

Certain U.S. Government Securities such as U.S. Treasury bills, notes and bonds and mortgage-related securities guaranteed by the GNMA, are supported by the full faith and credit of the United States; others, such as those of Federal Home Loan Banks (“FHLBs”) or the Federal Home Loan Mortgage Corporation (“FHLMC”), are supported by the right of the issuer to borrow from the U.S. Treasury; others, such as those of the FNMA, are supported by the discretionary authority of the U.S. Government to purchase the agency’s obligations; and still others are supported only by the credit of the agency, instrumentality or corporation. U.S. government securities are subject to market risk, interest rate risk and credit risk. Although legislation has been enacted to support certain government sponsored entities, including the FHLBs, FHLMC and FNMA, there is no assurance that the obligations of such entities will be satisfied in full, or that such obligations will not decrease in value or default. It is difficult, if not impossible, to predict the future political, regulatory or economic changes that could impact the government sponsored entities and the values of their related securities or obligations. In addition, certain governmental entities, including FNMA and FHLMC, have been subject to regulatory scrutiny regarding their accounting policies and practices and other concerns that may result in legislation, changes in regulatory oversight and/or other consequences that could adversely affect the credit quality, availability or investment character of securities issued by these entities. Yields available from U.S. Government debt securities are generally lower than the yields available from such other securities. The values of U.S. Government Securities change as interest rates fluctuate.

Periodically, uncertainty regarding the status of negotiations in the U.S. government to increase the statutory debt ceiling could increase the risk that the U.S. government may default on payments on certain U.S. government securities, cause the credit rating of the U.S. government to be downgraded, increase volatility in the stock and bond markets, result in higher interest rates, reduce prices of U.S. Treasury and other securities, and/or increase the costs of various kinds of debt. If a government-sponsored entity is negatively impacted by legislative or regulatory action (or lack thereof), is unable to meet

its obligations, or its creditworthiness declines, the performance of a fund that holds securities of the entity will be adversely impacted.

Valuation Risk

Certain securities in which the Fund invests may be less liquid and more difficult to value than other types of securities. Investments for which market quotations are not readily available are valued at fair value as determined in good faith pursuant to Rule 2a-5 under the 1940 Act. Fair value pricing may require subjective determinations about the value of a security or other asset. As a result, there can be no assurance that fair value pricing will result in adjustments to the prices of securities or other assets or that fair value pricing will reflect actual market value, and it is possible that the fair value determined for a security or other asset will be materially different from quoted or published prices, from the prices used by others for the same security or other asset and/or from the value that actually could be or is realized upon the sale of that security or other asset.

Zero-Coupon Bond, Step-Ups and Payment-In-Kind Securities Risk

The market prices of zero-coupon, step-ups and payment-in-kind securities are generally more volatile than the prices of securities that pay interest periodically and in cash and are likely to respond to changes in interest rates to a greater degree than other types of debt securities with similar maturities and credit quality. Because zero-coupon securities bear no interest, their prices are especially volatile. And because zero-coupon bondholders do not receive interest payments, the prices of zero-coupon securities generally fall more dramatically than those of bonds that pay interest on a current basis when interest rates rise. The market for zero-coupon and payment-in-kind securities may suffer decreased liquidity. In addition, as these securities may not pay cash interest, the Fund’s investment exposure to these securities and their risks, including credit risk, will increase during the time these securities are held in the Fund’s portfolio. Further, to maintain its qualification for treatment as a RIC and to avoid Fund-level U.S. federal income and/or excise taxes, the Fund is required to distribute to its shareholders any income it is deemed to have received in respect of such investments, notwithstanding that cash has not been received currently, and the value of paid-in-kind interest. Consequently, the Fund may have to dispose of portfolio securities under disadvantageous circumstances to generate the cash or may have to leverage itself by borrowing the cash to satisfy this distribution requirement. The required distributions, if any, would result in an increase in the Fund’s exposure to these securities. Zero coupon bonds, step-ups and payment-in-kind securities allow an issuer to avoid or delay the need to generate cash to meet current interest payments and, as a result, may involve greater credit risk than bonds that pay interest currently or in cash. The Fund would be required to distribute the income on these instruments as it

accrues, even though the Fund will not receive the income on a current basis or in cash. Thus, the Fund may sell other investments, including when it may not be advisable to do so, to make income distributions to its shareholders.

Use of Derivatives

A Fund may use derivative instruments for other purposes, including to seek to increase liquidity, provide efficient portfolio management, broaden investment opportunities (including taking short or negative positions), implement a tax or cash management strategy, gain exposure to a particular security or segment of the market, modify the effective duration of the Fund’s portfolio investments and/or enhance total return.

A Fund may (but is not required to) use various investment strategies to attempt to hedge exposure to reduce the risk of price fluctuations of its portfolio securities, the risk of loss, and to preserve capital. Derivatives strategies and instruments that a Fund may use include, among others, reverse repurchase agreements; interest rate swaps; total return swaps; credit default swaps; basis swaps; other types of swap agreements or options thereon; dollar rolls; futures and forward contracts (including foreign currency exchange contracts); short sales; options on financial futures; options based on either an index of municipal securities or taxable debt securities whose prices, PIMCO believes, correlate with the prices of the Fund’s investments; other derivative transactions; loans of portfolio securities and when-issued, delayed delivery and forward commitment transactions. Income earned by a Fund from its hedging and related transactions may be subject to one or more special U.S. federal income tax rules that can affect the amount, timing and/or character of distributions to holders of the Fund’s Common Shares. For instance, many hedging activities will be treated as capital gain and, if not offset by net realized capital loss, will be distributed to shareholders in taxable distributions. If effectively used, hedging strategies will offset in varying percentages losses incurred on a Fund’s investments due to adverse interest rate changes. There is no assurance that these hedging strategies will be available at any time or that PIMCO will determine to use them for a Fund or, if used, that the strategies will be successful. PIMCO may determine not to engage in hedging strategies or to do so only in unusual circumstances or market conditions. In addition, a Fund may be subject to certain restrictions on its use of hedging strategies imposed by guidelines of one or more ratings agencies that may issue ratings on any preferred shares issued by the Fund.

A Fund may take certain actions if short-term interest rates increase or market conditions otherwise change (or the Fund anticipates such an increase or change) and the Fund’s leverage begins (or is expected) to adversely affect holders of its Common Shares. In order to attempt to offset such a negative impact of leverage on holders of Common Shares, a Fund may shorten the average maturity or duration of its investment portfolio (by investing in short-term, high quality securities or implementing certain hedging strategies). Should a Fund issue preferred shares, the Fund also may attempt to reduce leverage by redeeming or otherwise purchasing preferred shares or by reducing any holdings in other instruments that create leverage. The success of any such attempt to limit leverage risk depends on PIMCO’s ability to accurately predict interest rate or other market changes. Because of the difficulty of making such predictions, a Fund may not be successful in managing its interest rate exposure in the manner described above.

In addition, each Fund has adopted certain investment limitations designed to limit investment risk. See “Fundamental Investment Restrictions” below for a description of these limitations.

Effects of Leverage [Text Block]

Effects of Leverage1 (Unaudited)

The following table is furnished in response to requirements of the SEC. It is designed to illustrate the effects of leverage through the use of senior securities, as that term is defined under Section 18 of the 1940 Act, on Common Share total return, assuming investment portfolio total returns (consisting of income and changes in the value of investments held in a Fund’s portfolio) of -10%, -5%, 0%, 5% and 10%. The table below reflects each Fund’s continued use of reverse repurchase agreements as of June 30, 2023 as a percentage of total managed assets (including assets attributable to such leverage), the estimated annual effective interest expense rate payable by the Fund on such instruments (based on market conditions as of June 30, 2023, and the annual return that the Fund’s portfolio must experience (net of expenses) in order to cover such costs of the reverse repurchase agreements based on such estimated annual effective interest expense rate. The information below does not reflect any Fund’s use of certain other forms of economic leverage achieved through the use of other

instruments or transactions not considered to be senior securities under the 1940 Act, such as covered credit default swaps or other derivative instruments.

The assumed investment portfolio returns in the table below are hypothetical figures and are not necessarily indicative of the investment portfolio returns experienced or expected to be experienced by the Fund. Your actual returns may be greater or less than those appearing below. In addition, actual borrowing expenses associated with reverse repurchase agreements (or dollar rolls or borrowings, if any) used by the Fund may vary frequently and may be significantly higher or lower than the rate used for the example below.

The information below does not reflect a Fund’s use of certain other forms of economic leverage achieved through the use of other instruments or transactions not considered to be senior securities under the 1940 Act, such as total return swaps or other derivative instruments.

Common Share total return is composed of two elements — the distributions paid by a Fund to holders of Common Shares (the amount of which is largely determined by the net investment income of the Fund after paying dividend payments on Preferred Shares and expenses on any forms of leverage outstanding) and gains or losses on the value of the securities and other instruments the Fund owns. As required by SEC rules, the table assumes that a Fund is more likely to suffer capital losses than to enjoy capital appreciation. For example, to assume a portfolio total return of 0%, a Fund must assume that the income it receives on its investments is entirely offset by losses in the value of those investments. This table reflects hypothetical performance of a Fund’s portfolio and not the actual performance of the Fund’s Common Shares, the value of which is determined by market forces and other factors.

Should a Fund elect to add additional leverage to its portfolio, any benefits of such additional leverage cannot be fully achieved until the proceeds resulting from the use of such leverage have been received by the Fund and invested in accordance with the Fund’s investment objectives and policies. As noted above, a Fund’s willingness to use additional leverage, and the extent to which leverage is used at any time, will depend on many factors, including, among other things, PIMCO’s assessment of the yield curve environment, interest rate trends, market conditions and other factors.

Anti-Takeover Provisions

The Fund’s Amended and Restated Agreement and Declaration of Trust (the “Declaration of Trust”), as applicable, includes provisions that could limit the ability of other entities or persons to acquire control of the Fund or to convert the Fund to open-end status. These provisions in the Declaration of Trust could have the effect of depriving the holders (“Common Shareholders”) of the Fund’s common shares of beneficial interest (“Common Shares”) of opportunities to sell their Common Shares at a premium over the then-current market price of the Common Shares or at NAV.

Asset Allocation Risk [Member]

General Description of Registrant [Abstract]

Risk [Text Block]

Asset Allocation Risk

The Fund’s investment performance depends upon how its assets are allocated and reallocated. A principal risk of investing in the Fund is that PIMCO may make less than optimal or poor asset allocation decisions. PIMCO employs an active approach to allocation among multiple fixed-income sectors, but there is no guarantee that such allocation techniques will produce the desired results. It is possible that PIMCO will focus on an investment that performs poorly or underperforms other investments under various market conditions. You could lose money on your investment in the Fund as a result of these allocation decisions.

Call Risk [Member]

General Description of Registrant [Abstract]

Risk [Text Block]

Call Risk

Call risk refers to the possibility that an issuer may exercise its right to redeem a fixed income security earlier than expected (a call). Issuers may call outstanding securities prior to their maturity for a number of reasons (e.g., declining interest rates, changes in credit spreads and improvements in the issuer’s credit quality). If an issuer calls a security in which the Fund has invested, the Fund may not recoup the full amount of its initial investment and may be forced to reinvest in lower-yielding securities, securities with greater credit risks or securities with other, less favorable features.

Certain Affiliations [Member]

General Description of Registrant [Abstract]

Risk [Text Block]

Certain Affiliations

Certain broker-dealers may be considered to be affiliated persons of the Fund and/or the Investment Manager due to their possible affiliations with Allianz SE, the ultimate parent of the Investment Manager, or another Allianz entity. Allianz Asset Management of America LP merged with Allianz Asset Management of America LLC (“Allianz Asset Management”), with the latter being the surviving entity, effective January 1, 2023. Following the merger, Allianz Asset

Management is PIMCO LLC’s managing member and direct parent entity. Absent an exemption from the SEC or other regulatory relief, the Fund is generally precluded from effecting certain principal transactions with affiliated brokers, and its ability to purchase securities being underwritten by an affiliated broker or a syndicate including an affiliated broker, or to utilize affiliated brokers for agency transactions, is subject to restrictions. This could limit the Fund’s ability to engage in securities transactions and take advantage of market opportunities.

The Fund has received exemptive relief from the SEC that, to the extent the Fund relies on such relief, permits it to (among other things) co-invest with certain other persons, including certain affiliates of the Investment Manager and certain public or private funds managed by the Investment Manager and its affiliates, subject to certain terms and conditions. The exemptive relief from the SEC with respect to co-investments imposes extensive conditions on any co-investments made in reliance on such relief.

Collateralized Bond Obligations, Collateralized Loan Obligations and Collateralized Debt Obligations Risk [Member]

General Description of Registrant [Abstract]

Risk [Text Block]

Collateralized Bond Obligations, Collateralized Loan Obligations and Collateralized Debt Obligations Risk

CBOs, CLOs and CDOs may charge management fees and administrative expenses. For CBOs, CLOs and CDOs, the cash flows from the trust are split into two or more portions, called tranches, varying in risk and yield. The riskiest portion is the equity tranche which generally bears losses in connection with the first defaults, if any, on the bonds or loans in the trust. A senior tranche from a CLO, CBO and CDO trust typically has higher credit ratings and lower yields than the underlying securities. CLO, CBO and CDO tranches, even senior ones, can experience substantial losses due to actual defaults, increased sensitivity to defaults due to collateral default and disappearance of protecting tranches, market anticipation of defaults and aversion to CLO, CBO or other CDO securities. The risks of an investment in a CLO, CBO or other CDO depend largely on the type of the collateral securities and the class/tranche of the instrument in which the Fund invests. Normally, CLOs, CBOs and other CDOs are privately offered and sold, and thus are not registered under the securities laws. Investments in CLOs, CBOs and CDOs may be or become illiquid. In addition to the normal risks associated with debt instruments (e.g., interest rate risk and credit risk), CLOs, CBOs and CDOs carry additional risks including, but not limited to: (i) the possibility that distributions from the collateral will not be adequate to make interest or other payments; (ii) the risk that the quality of the collateral may decline in value or default; (iii) the risk that the Fund may invest in CBOs, CLOs or other CDOs that are subordinate to other classes; and (iv) the risk that the complex structure of the security may not be fully understood at the time of investment and may produce disputes with the issuer or others and may produce unexpected investment results.

Confidential Information Access Risk [Member]

General Description of Registrant [Abstract]

Risk [Text Block]

Confidential Information Access Risk

In managing the Fund (and other PIMCO clients), PIMCO may from time to time have the opportunity to receive material, non-public information (“Confidential Information”) about the issuers of certain investments, including, without limitation, senior floating rate loans, other loans and related investments being considered for acquisition by the Fund or held in the Fund’s portfolio. For example, an issuer of privately placed loans considered by the Fund may offer to provide PIMCO with financial information and related documentation regarding the issuer that is not publicly available. Pursuant to applicable policies and procedures, PIMCO may (but is not required to) seek to avoid receipt of Confidential Information from the issuer so as to avoid possible restrictions on its ability to purchase and sell investments on behalf of the Fund and other clients to which such Confidential Information relates. In such circumstances, the Fund (and other PIMCO clients) may be disadvantaged in comparison to other investors, including with respect to the price the Fund pays or receives when it buys or sells an investment. Further, PIMCO’s and the Fund’s abilities to assess the desirability of proposed consents, waivers or amendments with respect to certain investments may be compromised if they are not privy to available Confidential Information. PIMCO may also determine to receive such Confidential Information in certain circumstances under its applicable policies and procedures. If PIMCO intentionally or unintentionally comes into possession of Confidential Information, it may be unable, potentially for a substantial period of time, to purchase or sell investments to which such Confidential Information relates.

Contingent Convertible Securities Risk [Member]

General Description of Registrant [Abstract]

Risk [Text Block]

Contingent Convertible Securities Risk

Contingent convertible securities (“CoCos”) have no stated maturity, have fully discretionary coupons and are typically issued in the form of subordinated debt instruments. CoCos generally either convert into equity or have their principal written down (including potentially to zero) upon the occurrence of certain triggering events (“triggers”) linked to regulatory capital thresholds or regulatory actions relating to the issuer’s continued viability. As a result, an investment by the Fund in CoCos is subject to the risk that coupon (i.e., interest) payments may be cancelled by the issuer or a regulatory authority in order to help the issuer absorb losses and the risk of total loss. An investment by the Fund in CoCos is also subject to the risk that, in the event of the liquidation, dissolution or winding-up of an issuer prior to a trigger event, the Fund’s rights and claims will generally rank junior to the claims of holders of the issuer’s other debt obligations and CoCos may also be treated as junior to an issuer’s other obligations and securities. In addition, if CoCos held by the Fund are converted into the issuer’s underlying equity securities following a trigger event, the Fund’s holding may be further subordinated due to the conversion from a debt to equity instrument. Further, the value of an investment in CoCos is unpredictable and will be

influenced by many factors and risks, including interest rate risk, credit risk, market risk and liquidity risk. An investment by the Fund in CoCos may result in losses to the Fund.

Convertible Securities Risk [Member]

General Description of Registrant [Abstract]

Risk [Text Block]

Convertible Securities Risk

The market values of convertible securities may decline as interest rates increase and, conversely, may increase as interest rates decline. A convertible security’s market value, however, tends to reflect the market price of the common stock of the issuing company when that stock price approaches or is greater than the convertible security’s “conversion price.” The conversion price is defined as the predetermined price at which the convertible security could be exchanged for the associated stock. As the market price of the underlying common stock declines, the price of the convertible security tends to be influenced more by the yield of the convertible security. Thus, it may not decline in price to the same extent as the underlying common stock. In the event of a liquidation of the issuing company, holders of convertible securities may be paid before the company’s common stockholders but after holders of any senior debt obligations of the company. Consequently, the issuer’s convertible securities generally entail less risk than its common stock but more risk than its other debt obligations. Convertible securities are often rated below investment grade or not rated.

Counterparty Risk [Member]

General Description of Registrant [Abstract]

Risk [Text Block]

Counterparty Risk

The Fund will be subject to credit risk with respect to the counterparties to the derivative contracts and other instruments entered into by the Fund or held by special purpose or structured vehicles in which the Fund invests. In the event that the Fund enters into a derivative transaction with a counterparty that subsequently becomes insolvent or becomes the subject of a bankruptcy case, the derivative transaction may be terminated in accordance with its terms and the Fund’s ability to realize its rights under the derivative instrument and its ability to distribute the proceeds could be adversely affected. If a counterparty becomes bankrupt or otherwise fails to perform its obligations under a derivative contract due to financial difficulties, the Fund may experience significant delays in obtaining any recovery (including recovery of any collateral it has provided to the counterparty) in a dissolution, assignment for the benefit of creditors, liquidation, winding-up, bankruptcy or other analogous proceeding. In addition, in the event of the insolvency of a counterparty to a derivative transaction, the derivative transaction would typically be terminated at its fair market value. If the Fund is owed this fair market value in the termination of the derivative transaction and its claim is unsecured, the Fund will be treated as a general creditor of such counterparty and will not have any claim with respect to any underlying security or asset. The Fund may obtain only a limited recovery or may obtain no recovery in such circumstances. While the

Fund may seek to manage its counterparty risk by transacting with a number of counterparties, concerns about the solvency of, or a default by, one large market participant could lead to significant impairment of liquidity and other adverse consequences for other counterparties.

CovenantLite Obligations Risk [Member]

General Description of Registrant [Abstract]

Risk [Text Block]

“Covenant-Lite” Obligations Risk

Covenant-lite obligations contain fewer maintenance covenants than other obligations, or no maintenance covenants, and may not include terms that allow the lender to monitor the performance of the borrower and declare a default if certain criteria are breached. Covenant-lite loans may carry more risk than traditional loans as they allow individuals and corporations to engage in activities that would otherwise be difficult or impossible under a covenant-heavy loan agreement. In the event of default, covenant-lite loans may exhibit diminished recovery values as the lender may not have the opportunity to negotiate with the borrower prior to default.

Credit Default Swaps Risk [Member]

General Description of Registrant [Abstract]

Risk [Text Block]

Credit Default Swaps Risk

Credit default swap agreements may involve greater risks than if the Fund had invested in the reference obligation directly since, in addition to general market risks, credit default swaps are subject to leverage risk, illiquidity risk, counterparty risk and credit risk. A buyer generally also will lose its investment and recover nothing should no credit event occur and the swap is held to its termination date. If a credit event were to occur, the value of any deliverable obligation received by the seller (if any), coupled with the upfront or periodic payments previously received, may be less than the full notional value it pays to the buyer, resulting in a loss of value to the seller. When the Fund acts as a seller of a credit default swap, it is exposed to many of the same risks of leverage described herein. As the seller, the Fund would receive a stream of payments over the term of the swap agreement provided that no event of default has occurred with respect to the referenced debt obligation upon which the swap is based. The Fund would effectively add leverage to its portfolio because, if a default occurs, the stream of payments may stop and, in addition to its total net assets, the Fund would be subject to investment exposure on the notional amount of the swap.

Although the Fund may seek to realize gains by selling credit default swaps that increase in value, to realize gains on selling credit default swaps, an active secondary market for such instruments must exist or the Fund must otherwise be able to close out these transactions at advantageous times. In addition to the risk of losses described above, if no such secondary market exists or the Fund is otherwise unable to close out these transactions at advantageous times, selling credit default swaps may not be profitable for the Fund.

The market for credit default swaps has become more volatile as the creditworthiness of certain counterparties has been questioned and/or

downgraded. The Fund will be subject to credit risk with respect to the counterparties to the credit default swap contract (whether a clearing corporation or another third party). If a counterparty’s credit becomes significantly impaired, multiple requests for collateral posting in a short period of time could increase the risk that the Fund may not receive adequate collateral. The Fund may exit its obligations under a credit default swap only by terminating the contract and paying applicable breakage fees, or by entering into an offsetting credit default swap position, which may cause the Fund to incur more losses.

Credit Risk [Member]

General Description of Registrant [Abstract]

Risk [Text Block]

Credit Risk

The Fund could lose money if the issuer or guarantor of a fixed income security (including a security purchased with securities lending collateral), or the counterparty to a derivatives contract, repurchase agreement or a loan of portfolio securities is unable or unwilling, or is perceived (whether by market participants, rating agencies, pricing services or otherwise) as unable or unwilling, to make timely principal and/or interest payments or to otherwise honor its obligations. The risk that such issuer, guarantor or counterparty is less willing or able to do so is heightened in market environments where interest rates are rising. The downgrade of the credit of a security held by the Fund may decrease its value. Measures such as average credit quality may not accurately reflect the true credit risk of the Fund. This is especially the case if the Fund consists of securities with widely varying credit ratings. Securities are subject to varying degrees of credit risk, which are often reflected in credit ratings. Credit risk is greater to the extent the Fund uses leverage or derivatives. Rising or high interest rates may deteriorate the credit quality of an issuer or counterparty, particularly if an issuer or counterparty faces challenges rolling or refinancing its obligations.

CSDR Related Risk [Member]

General Description of Registrant [Abstract]

Risk [Text Block]

CSDR Related Risk

The European Union has adopted a settlement discipline regime under Regulation (EU) No 909/2014 and the Settlement Discipline RTS as they may be modified from time to time (“CSDR”), which will have phased compliance dates. It aims to reduce the number of settlement fails that occur in EEA central securities depositories (“CSDs”) and address settlement fails where they occur. The key elements of the regime are: (i) mandatory buy-ins — if a settlement fail continues for a specified period of time after the intended settlement date, a buy-in process must be initiated to effect the settlement; (ii) cash penalties — EEA CSDs are required to impose cash penalties on participants that cause settlement fails and distribute these to receiving participants; and (iii) allocations and confirmations — EEA investment firms are required to take measures to prevent settlement fails, including putting in place arrangements with their professional clients to communicate securities allocations and transaction confirmations. These requirements apply to transactions in transferable securities (e.g., shares and bonds), money market instruments, units in funds

and emission allowances that are to be settled via an EEA CSD and, in the case of cash penalties and buy-in requirements only, are admitted to trading or traded on an EEA trading venue or cleared by an EEA central counterparty. If the Fund enters into in-scope transactions, the CSDR settlement discipline regime may result in increased operational and compliance costs being borne directly or indirectly by the Fund. CSDR may also affect liquidity and increase trading costs associated with relevant securities. If in-scope transactions are subject to additional expenses and penalties as a consequence of the CSDR settlement discipline regime, such expenses and penalties may be charged to the relevant Fund.

Currency Risk [Member]

General Description of Registrant [Abstract]

Currency Risk

If the Fund invests directly in foreign (non-U.S.) currencies or in securities that trade in, and receive revenues in, foreign (non-U.S.) currencies, or in derivatives or other instruments that provide exposure to foreign (non-U.S.) currencies, it will be subject to the risk that those currencies will decline in value relative to the U.S. dollar, or, in the case of hedging positions, that the U.S. dollar will decline in value relative to the currency being hedged. Although the Fund may attempt to hedge its currency exposure into the U.S. dollar, it may not be successful in reducing the effects of currency fluctuations. The Fund may also hedge from one foreign currency to another. In addition, the Fund’s use of currency hedging may not be successful and the use of such strategies may lower the Fund’s potential returns.

Investments denominated in foreign (non-U.S.) currencies or that trade in and receive revenues in, foreign (non-U.S.) currencies, derivatives or other instruments that provide exposure to foreign (non-U.S.) currencies, are subject to the risk that those currencies will decline in value relative to the U.S. dollar, or, in the case of hedging positions, that the U.S. dollar will decline in value relative to the currency being hedged.

Currency rates in foreign (non-U.S.) countries may fluctuate significantly over short periods of time for a number of reasons, including changes in interest rates, rates of inflation, balance of payments and governmental surpluses or deficits, intervention (or the failure to intervene) by U.S. or foreign (non-U.S.) governments, central banks or supranational entities such as the International Monetary Fund, or by the imposition of currency controls or other political developments in the United States or abroad. These fluctuations may have a significant adverse impact on the value of the Fund’s portfolio and/or the level of Fund distributions made to Common Shareholders. There is no assurance that a hedging strategy, if used, will be successful.

Moreover, currency hedging techniques may be unavailable with respect to emerging market currencies. As a result, the Fund’s investments in foreign currency-denominated, and especially emerging market-currency denominated, securities may reduce the returns of the Fund.

Cyber Security Risk [Member]

General Description of Registrant [Abstract]

Risk [Text Block]

Cyber Security Risk

As the use of technology has become more prevalent in the course of business, the Fund is potentially more susceptible to operational and information security risks resulting from breaches in cyber security. A breach in cyber security refers to both intentional and unintentional cyber events from outside threat actors or internal resources that may, among other things, cause the Fund to lose proprietary information, suffer data corruption and/or destruction, lose operational capacity, result in the unauthorized release or other misuse of confidential information, or otherwise disrupt normal business operations. Cyber security breaches may involve unauthorized access to the Fund’s digital information systems (e.g., through “hacking” or malicious software coding), and may come from multiple sources, including outside attacks such as denial-of-service attacks (i.e., efforts to make network services unavailable to intended users) or cyber extortion, including exfiltration of data held for ransom and/or “ransomware” attacks that renders systems inoperable until ransom is paid, or insider actions. In addition, cyber security breaches involving the Fund’s third party service providers (including but not limited to advisers, sub-advisers, administrators, transfer agents, custodians, vendors, suppliers, distributors and other third parties), trading counterparties or issuers in which the Fund invests can also subject the Fund to many of the same risks associated with direct cyber security breaches or extortion of company data. Moreover, cyber security breaches involving trading counterparties or issuers in which the Fund invests could adversely impact such counterparties or issuers and cause the Fund’s investments to lose value. In addition, work-from-home arrangements by the Fund, the Investment Manager or their service providers could increase all of the above risks, create additional data and information accessibility concerns, and make the Fund, the Investment Manager or their service providers susceptible to operational disruptions, any of which could adversely impact their operations.

Cyber security failures or breaches may result in financial losses to the Fund and its shareholders. These failures or breaches may also result in disruptions to business operations, potentially resulting in financial losses; interference with the Fund’s ability to calculate its NAV, process shareholder transactions or otherwise transact business with shareholders; impediments to trading; violations of applicable privacy and other laws; regulatory fines; penalties; third party claims in litigation; reputational damage; reimbursement or other compensation costs; additional compliance and cyber security risk management costs and other adverse consequences. In addition, substantial costs may be incurred in order to prevent any cyber incidents in the future.

Like with operational risk in general, the Fund has established business continuity plans and risk management systems designed to reduce the risks associated with cyber security. However, there are

inherent limitations in these plans and systems, including that certain risks may not have been identified, in large part because different or unknown threats may emerge in the future. As such, there is no guarantee that such efforts will succeed, especially because the Fund does not directly control the cyber security systems of issuers in which the Fund may invest, trading counterparties or third party service providers to the Fund. Such entities have experienced cyber attacks and other attempts to gain unauthorized access to systems from time to time, and there is no guarantee that efforts to prevent or mitigate the effects of such attacks or other attempts to gain unauthorized access will be successful. There is also a risk that cyber security breaches may not be detected. The Fund and its shareholders may suffer losses as a result of a cyber security breach related to the Fund, its service providers, trading counterparties or the issuers in which the Fund invests.

Debt Securities Risk [Member]

General Description of Registrant [Abstract]

Risk [Text Block]

Debt Securities Risk

Debt securities are generally subject to the risks described below and further herein:

Issuer risk.  The value of debt securities may decline for a number of reasons that directly relate to the issuer, such as management performance, financial leverage, reduced demand for the issuer’s goods and services, historical and prospective earnings of the issuer and the value of the assets of the issuer.

Interest rate risk.  The market value of debt securities changes in response to interest rate changes and other factors. Interest rate risk is the risk that prices of debt securities will increase as interest rates fall and decrease as interest rates rise, which would be reflected in the Fund’s NAV. The Fund may lose money if short-term or long-term interest rates rise sharply in a manner not anticipated by the Fund’s management. Moreover, because rates on certain floating rate debt securities typically reset only periodically, changes in prevailing interest rates (and particularly sudden and significant changes) can be expected to cause some fluctuations in the NAV of the Fund to the extent that it invests in floating rate debt securities.

Prepayment risk.  During periods of declining interest rates, borrowers may prepay principal. This may force the Fund to reinvest in lower yielding securities, resulting in a possible decline in the Fund’s income and distributions.

Credit risk.  Credit risk is the risk that one or more debt securities in the Fund’s portfolio will decline in price or fail to pay interest or principal when due because the issuer of the security experiences a decline in its financial status. Credit risk is increased when a portfolio security is downgraded or the perceived creditworthiness of the issuer deteriorates.

Reinvestment risk.  Reinvestment risk is the risk that income from the Fund’s portfolio will decline if the Fund invests the proceeds from matured, traded or called fixed income securities at market interest rates that are below the portfolio’s current earnings rate.

Duration and maturity risk.  The Fund may seek to adjust the duration or maturity of its investments in debt securities based on its assessment of current and projected market conditions. The Fund may incur costs in seeking to adjust the average duration or maturity of its portfolio of debt securities. There can be no assurances that the Fund’s assessment of current and projected market conditions will be correct or that any strategy to adjust duration or maturity will be successful.

In addition, from time to time, uncertainty regarding the status of negotiations in the U.S. government to increase the statutory debt ceiling could impact the creditworthiness of the United States and could impact the liquidity and value of U.S. Government and other securities and ultimately the Fund.

Derivatives Risk [Member]

General Description of Registrant [Abstract]

Risk [Text Block]

Derivatives Risk

The Fund may, but is not required to, utilize a variety of derivative instruments (both long and short positions) for investment or risk management purposes. Derivatives are financial contracts whose value depends on, or is derived from, the value of an underlying asset, reference rate or index. For example, the Fund may use derivative instruments for purposes of increasing liquidity, providing efficient portfolio management, broadening investment opportunities (including taking short or negative positions), implementing a tax or cash management strategy, gaining exposure to a particular security or segment of the market, modifying the effective duration of the Fund’s portfolio investments and/or enhancing total return.

The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. Derivatives and other similar instruments (referred to collectively as “derivatives”), which may increase market exposure are subject to a number of risks including leverage risk, liquidity risk (which may be heightened for highly customized derivatives), interest rate risk, market risk, counterparty (including credit) risk, operational risk (such as documentation issues, settlement issues and systems failures), legal risk (such as insufficient documentation, insufficient capacity or authority of a counterparty, and issues with the legality or enforceability of a contract), counterparty risk, tax risk and management risk, as well as risks arising from changes in applicable requirements, risks arising from margin requirements and risks arising from mispricing or valuation complexity. They also involve the risk that changes in the value of a derivative instrument may not correlate perfectly with the underlying asset, rate or index. By investing in a

derivative instrument, the Fund could lose more than the initial amount invested, and derivatives may increase the volatility of the Fund, especially in unusual or extreme market conditions. Certain derivatives have the potential for unlimited loss, regardless of the size of the initial investment. The 1940 Act and related rules no longer require asset segregation for derivatives transactions, however asset segregation and posting of collateral may still be utilized for risk management or other purposes. The Fund may be required to hold additional cash or sell other investments in order to obtain cash to close out a position and changes in the value of a derivative may also create margin delivery or settlement payment obligations for the Fund. Also, suitable derivative transactions may not be available in all circumstances and there can be no assurance that the Fund will engage in these transactions to reduce exposure to other risks when that would be beneficial or that, if used, such strategies will be successful. The Fund’s use of derivatives may increase or accelerate the amount of taxes payable by Common Shareholders.

Over-the-counter (“OTC”) derivatives are also subject to the risk that a counterparty to the transaction will not fulfill its contractual obligations to the other party, as many of the protections afforded to centrally cleared derivative transactions might not be available for OTC derivatives. The primary credit risk on derivatives that are exchange-traded or traded through a central clearing counterparty resides with the Fund’s clearing broker, or the clearinghouse itself.

Participation in the markets for derivative instruments involves investment risks and transaction costs to which the Fund may not be subject absent the use of these strategies. The skills needed to successfully execute derivative strategies may be different from those needed for other types of transactions. If the Fund incorrectly forecasts the value and/or creditworthiness of securities, currencies, interest rates, counterparties or other economic factors involved in a derivative transaction, the Fund might have been in a better position if the Fund had not entered into such derivative transaction. In evaluating the risks and contractual obligations associated with particular derivative instruments, it is important to consider that certain derivative transactions may be modified or terminated only by mutual consent of the Fund and its counterparty.

Therefore, it may not be possible for the Fund to modify, terminate, or offset the Fund’s obligations or the Fund’s exposure to the risks associated with a derivative transaction prior to its scheduled termination or maturity date, which may create a possibility of increased volatility and/or decreased liquidity to the Fund. Hedges are sometimes subject to imperfect matching between the derivative and the underlying instrument, and there can be no assurance that the Fund’s hedging transactions will be effective. In such case, the Fund may lose money.

Because the markets for certain derivative instruments (including markets located in foreign countries) are relatively new and still developing, appropriate derivative transactions may not be available in all circumstances for risk management or other purposes. Upon the expiration of a particular contract, the Fund may wish to retain the Fund’s position in the derivative instrument by entering into a similar contract but may be unable to do so if the counterparty to the original contract is unwilling to enter into the new contract and no other appropriate counterparty can be found. When such markets are unavailable, the Fund will be subject to increased liquidity and investment risk.

The Fund may enter into opposite sides of interest rate swap and other derivatives for the principal purpose of generating distributable gains on the one side (characterized as ordinary income for tax purposes) that are not part of the Fund’s duration or yield curve management strategies (“paired swap transactions”), and with a substantial possibility that the Fund will experience a corresponding capital loss and decline in NAV with respect to the opposite side transaction (to the extent it does not have corresponding offsetting capital gains). Consequently, Common Shareholders may receive distributions and owe tax on amounts that are effectively a taxable return of the shareholder’s investment in the Fund, at a time when their investment in the Fund has declined in value, which tax may be at ordinary income rates. The tax treatment of certain derivatives in which the Fund invests may be unclear and thus subject to recharacterization. Any recharacterization of payments made or received by the Fund pursuant to derivatives potentially could affect the amount, timing or character of Fund distributions. In addition, the tax treatment of such investment strategies may be changed by regulation or otherwise.

When a derivative is used as a hedge against a position that the Fund holds, any loss generated by the derivative generally should be substantially offset by gains on the hedged investment, and vice versa. Although hedging can reduce or eliminate losses, it can also reduce or eliminate gains. Hedges are sometimes subject to imperfect matching between the derivative and the underlying instrument, and there can be no assurance that the Fund’s hedging transactions will be effective. The regulation of the derivatives markets has increased over the past several years, and additional future regulation of the derivatives markets may make derivatives more costly, may limit the availability or reduce the liquidity of derivatives, or may otherwise adversely affect the value or performance of derivatives. Any such adverse future developments could impair the effectiveness or raise the costs of the Fund’s derivative transactions, impede the employment of the Fund’s derivatives strategies, or adversely affect the Fund’s performance.

Distressed and Defaulted Securities Risk [Member]

General Description of Registrant [Abstract]

Risk [Text Block]

Distressed and Defaulted Securities Risk

Investments in the securities of financially distressed issuers involve substantial risks, including the risk of default. Distressed securities generally trade significantly below “par” or full value because investments in such securities and debt of distressed issuers or issuers in default are considered speculative and involve substantial risks in addition to the risks of investing in high-yield bonds. Such investments may be in default at the time of investment. In addition, these securities may fluctuate more in price, and are typically less liquid. The Fund also will be subject to significant uncertainty as to when, and in what manner, and for what value obligations evidenced by securities of financially distressed issuers will eventually be satisfied. Defaulted obligations might be repaid only after lengthy workout or bankruptcy proceedings, during which the issuer might not make any interest or other payments. In any such proceeding relating to a defaulted obligation, the Fund may lose its entire investment or may be required to accept cash or securities with a value substantially less than its original investment. Moreover, any securities received by the Fund upon completion of a workout or bankruptcy proceeding may be less liquid, speculative or restricted as to resale. Similarly, if the Fund participates in negotiations with respect to any exchange offer or plan of reorganization with respect to the securities of a distressed issuer, the Fund may be restricted from disposing of such securities. To the extent that the Fund becomes involved in such proceedings, the Fund may have a more active participation in the affairs of the issuer than that assumed generally by an investor. The Fund may incur additional expenses to the extent it is required to seek recovery upon a default in the payment of principal or interest on its portfolio holdings.

Also among the risks inherent in investments in a troubled issuer is that it frequently may be difficult to obtain information as to the true financial condition of such issuer. PIMCO’s judgments about the credit quality of a financially distressed issuer and the relative value of its securities may prove to be wrong.

Emerging Markets Risk [Member]

General Description of Registrant [Abstract]

Risk [Text Block]

Emerging Markets Risk

Foreign (non U.S.) investment risk may be particularly high to the extent that the Fund invests in securities of issuers based in or doing business in emerging market countries or invests in securities denominated in the currencies of emerging market countries. Investing in securities of issuers based in or doing business in emerging markets entails all of the risks of investing in foreign securities noted above, but to a heightened degree.

Investments in emerging market countries pose a greater degree of systemic risk (i.e., the risk of a cascading collapse of multiple institutions within a country, and even multiple national economies). The inter-relatedness of economic and financial institutions within and among emerging market economies has deepened over the years, with the effect that institutional failures and/or economic difficulties that are of initially limited scope may spread throughout a country, a region or all or most emerging market countries. This may undermine any attempt by the Fund to reduce risk through geographic diversification of its portfolio.

There is a heightened possibility of imposition of withholding taxes on interest or dividend income generated from emerging market securities. Governments of emerging market countries may engage in confiscatory taxation or expropriation of income and/or assets to raise revenues or to pursue a domestic political agenda. In the past, emerging market countries have nationalized assets, companies and even entire sectors, including the assets of foreign investors, with inadequate or no compensation to the prior owners. There can be no assurance that the Fund will not suffer a loss of any or all of its investments, or interest or dividends thereon, due to adverse fiscal or other policy changes in emerging market countries.

There is also a greater risk that an emerging market government may take action that impedes or prevents the Fund from taking income and/or capital gains earned in the local currency and converting into U.S. dollars (i.e., “repatriating” local currency investments or profits). Certain emerging market countries have sought to maintain foreign exchange reserves and/or address the economic volatility and dislocations caused by the large international capital flows by controlling or restricting the conversion of the local currency into other currencies. This risk tends to become more acute when economic conditions otherwise worsen. There can be no assurance that if the Fund earns income or capital gains in an emerging market currency or PIMCO otherwise seeks to withdraw the Fund’s investments from a

given emerging market country, capital controls imposed by such country will not prevent, or cause significant expense, or delay in, doing so.

Bankruptcy law and creditor reorganization processes may differ substantially from those in the United States, resulting in greater uncertainty as to the rights of creditors, the enforceability of such rights, reorganization timing and the classification, seniority and treatment of claims. In certain emerging market countries, although bankruptcy laws have been enacted, the process for reorganization remains highly uncertain. In addition, it may be impossible to seek legal redress against an issuer that is a sovereign state.

Emerging market countries typically have less established legal, accounting, recordkeeping and financial reporting systems than those in more developed markets, which may reduce the scope or quality of financial information available to investors. Governments in emerging market countries are often less stable and more likely to take extra-legal action with respect to companies, industries, assets, or foreign ownership than those in more developed markets. Moreover, it can be more difficult for investors to bring litigation or enforce judgments against issuers in emerging markets or for U.S. regulators to bring enforcement actions against such issuers. The Fund may also be subject to emerging markets risk if it invests in derivatives or other securities or instruments whose value or return are related to the value or returns of emerging markets securities.

Other heightened risks associated with emerging markets investments include without limitation (i) risks due to less social, political and economic stability; (ii) the smaller size of the market for such securities and a lower volume of trading, resulting in a lack of liquidity and in price volatility; (iii) certain national policies which may restrict the Fund’s investment opportunities, including sanctions and restrictions on investing in issuers or industries deemed sensitive to relevant national interests and requirements that government approval be obtained prior to investment by foreign persons; (iv) certain national policies that may restrict the Fund’s repatriation of investment income, capital or the proceeds of sales of securities, including temporary restrictions on foreign capital remittances; (v) the lack of uniform accounting and auditing standards and/or standards that may be significantly different from the standards required in the United States; (vi) less publicly available financial and other information regarding issuers; (vii) potential difficulties in enforcing contractual obligations; and (viii) higher rates of inflation, higher interest rates and other economic concerns. The Fund may invest to a substantial extent in emerging market securities that are denominated in local currencies, subjecting the Fund to a greater degree of foreign currency risk. Also, investing in emerging market countries may entail purchases of securities of issuers that are insolvent, bankrupt or otherwise of

questionable ability to satisfy their payment obligations as they become due, subjecting the Fund to a greater amount of credit risk and/or high yield risk. The economy of some emerging markets may be particularly exposed to or affected by a certain industry or sector, and therefore issuers and/or securities of such emerging markets may be more affected by the performance of such industries or sectors.

Distribution Rate Risk [Member]

General Description of Registrant [Abstract]

Risk [Text Block]

Distribution Rate Risk

Although the Fund may seek to maintain level distributions, the Fund’s distribution rates may be affected by numerous factors, including but not limited to changes in realized and projected market returns, fluctuations in market interest rates, Fund performance, and other factors. There can be no assurance that a change in market conditions or other factors will not result in a change in the Fund’s distribution rate or that the rate will be sustainable in the future.

For instance, during periods of low or declining interest rates, the Fund’s distributable income and dividend levels may decline for many reasons. For example, the Fund may have to deploy uninvested assets (whether from sales of Fund shares, proceeds from matured, traded or called debt obligations or other sources) in new, lower yielding

instruments. Additionally, payments from certain instruments that may be held by the Fund (such as variable and floating rate securities) may be negatively impacted by declining interest rates, which may also lead to a decline in the Fund’s distributable income and dividend levels.

Equity Securities and Related Market Risk [Member]

General Description of Registrant [Abstract]

Risk [Text Block]

Equity Securities and Related Market Risk

The market price of common stocks and other equity securities may go up or down, sometimes rapidly or unpredictably. Equity securities may decline in value due to factors affecting equity securities markets generally, particular industries represented in those markets, or the issuer itself. The values of equity securities may decline due to real or perceived adverse economic conditions, changes in the general outlook for corporate earnings, changes in interest or currency rates, adverse changes to credit markets or adverse investor sentiment generally. They may also decline due to labor shortages or increased production costs and competitive conditions within an industry. Equity securities generally have greater price volatility than bonds and other debt securities.

Different types of equity securities provide different voting and dividend rights and priority in the event of the bankruptcy and/or insolvency of the issuer. In addition to common stock, equity securities may include preferred securities, convertible securities and warrants. Equity securities other than common stock are subject to many of the same risks as common stock, although possibly to different degrees. The risks of equity securities are generally magnified in the case of equity investments in distressed companies.

Focused Investment Risk [Member]

General Description of Registrant [Abstract]

Risk [Text Block]

Focused Investment Risk

To the extent that the Fund focuses its investments in a particular sector, it may be susceptible to loss due to adverse developments affecting that sector, including (but not limited to): governmental regulation; inflation; rising interest rates; cost increases in raw materials, fuel and other operating expenses; technological innovations that may render existing products and equipment obsolete; competition from new entrants; high research and development costs; increased costs associated with compliance with environmental or other governmental regulations; and other economic, business or political developments specific to that sector. Furthermore, the Fund may invest a substantial portion of its assets in companies in related sectors that may share common characteristics, are often subject to similar business risks and regulatory burdens, and whose securities may react similarly to the types of developments described above, which will subject the Fund to greater risk. The Fund also will be subject to focused investment risk to the extent that it invests a substantial portion of its assets in a particular issuer, market, asset class, country or geographic region.

Foreign (NonU.S.) Investment Risk [Member]

General Description of Registrant [Abstract]

Risk [Text Block]

Foreign (Non-U.S.) Investment Risk

Foreign (non-U.S.) securities may experience more rapid and extreme changes in value than securities of U.S. issuers or securities that trade exclusively in U.S. markets. The securities markets of many foreign countries are relatively small, with a limited number of companies representing a small number of industries. Additionally, issuers of foreign (non-U.S.) securities are usually not subject to the same degree of regulation as U.S. issuers. Reporting, accounting, auditing and custody standards of foreign countries differ, in some cases significantly, from U.S. standards. Global economies and financial markets are becoming increasingly interconnected, and conditions and events in one country, region or financial market may adversely impact issuers in a different country, region or financial market. Foreign (non-U.S.) market trading hours, clearance and settlement procedures, and holiday schedules may limit the Fund’s ability to buy and sell securities. Investments in foreign (non-U.S.) markets may also be adversely affected by governmental actions such as the imposition of capital controls, nationalization of companies or industries, expropriation of assets or the imposition of punitive taxes. The governments of certain countries may prohibit or impose substantial restrictions on foreign (non-U.S.) investing in their capital markets or in certain sectors or industries. In addition, a foreign (non-U.S.) government may limit or cause delay in the convertibility or repatriation of its currency which would adversely affect the U.S. dollar value and/or liquidity of investments denominated in that currency. Certain foreign (non-U.S.) investments may become less liquid in response to market developments or adverse investor perceptions, or become illiquid after purchase by the Fund, particularly during periods of market turmoil. A reduction in trading in securities of issuers located in countries whose economies are heavily dependent upon trading with key partners may have an adverse impact on a Fund’s investments.

Also, nationalization, expropriation or confiscatory taxation, unstable governments, decreased market liquidity, currency blockage, market disruptions, political changes, security suspensions or diplomatic developments or the imposition of sanctions or other similar measures could adversely affect the Fund’s investments in a foreign (non-U.S.) country. In the event of nationalization, expropriation or other confiscation, the Fund could lose its entire investment in foreign (non-U.S.) securities. The type and severity of sanctions and other similar measures, including counter sanctions and other retaliatory actions, that may be imposed could vary broadly in scope, and their impact is difficult to ascertain. These types of measures may include, but are not limited to, banning a sanctioned country or certain persons or entities associated with such country from global payment systems that facilitate cross-border payments, restricting the settlement of securities transactions by certain investors, and freezing the assets of

particular countries, entities or persons. The imposition of sanctions and other similar measures could, among other things, result in a decline in the value and/or liquidity of securities issued by the sanctioned country or companies located in or economically tied to the sanctioned country, downgrades in the credit ratings of the sanctioned country’s securities or those of companies located in or economically tied to the sanctioned country, currency devaluation or volatility, and increased market volatility and disruption in the sanctioned country and throughout the world. Sanctions and other similar measures could directly or indirectly limit or prevent a Fund from buying and selling securities (in the sanctioned country and other markets), significantly delay or prevent the settlement of securities transactions, and adversely impact a Fund’s liquidity and performance. Adverse conditions in a certain region can adversely affect securities of other countries whose economies appear to be unrelated. To the extent that the Fund invests a significant portion of its assets in a specific geographic region or in securities denominated in a particular foreign (non-U.S.) currency, the Fund will generally have more exposure to regional economic risks, including weather emergencies and natural disasters, associated with foreign (non-U.S.) investments. Foreign (non-U.S.) securities may also be less liquid (particularly during market closures due to local holidays or other reasons) and more difficult to value than securities of U.S. issuers.

The Fund may invest in securities and instruments that are economically tied to Russia. Investments in Russia are subject to various risks such as, but not limited to political, economic, legal, market and currency risks. The risks include uncertain political and economic policies, short term market volatility, poor accounting standards, corruption and crime, an inadequate regulatory system, regional armed conflict and unpredictable taxation. Investments in Russia are particularly subject to the risk that further economic sanctions, export and import controls, and other similar measures may be imposed by the United States and/or other countries. Other similar measures may include, but are not limited to, banning or expanding bans on Russia or certain persons or entities associated with Russia from global payment systems that facilitate cross-border payments, restricting the settlement of securities transactions by certain investors, and freezing Russian assets or those of particular countries, entities or persons with ties to Russia (e.g. Belarus). Such sanctions and other similar measures — which may impact companies in many sectors, including energy, financial services, technology, accounting, quantum computing, shipping, aviation, metals and mining, defense, architecture, engineering, construction, manufacturing and transportation, among others — and Russia’s countermeasures may negatively impact the Fund’s performance and/or ability to achieve its investment objectives. For example, certain investments may be prohibited and/or existing investments

may become illiquid (e.g., in the event that transacting in certain existing investments is prohibited, securities markets close, or market participants cease transacting in certain investments in light of geopolitical events, sanctions or related considerations), which could render any such securities held by the Fund unmarketable for an indefinite period of time and/or cause the Fund to sell portfolio holdings at a disadvantageous time or price or to continue to hold investments that the Fund no longer seeks to hold. In addition, such sanctions or other similar measures, and the Russian government’s response, could result in a downgrade of Russia’s credit rating or of securities of issuers located in or economically tied to Russia, devaluation of Russia’s currency and/or increased volatility with respect to Russian securities and the ruble. Moreover, disruptions caused by Russian military action or other actions (including cyberattacks, espionage or other asymmetric measures) or resulting actual or threatened responses to such activity may impact Russia’s economy and Russian and other issuers of securities in which the Fund is invested. Such resulting actual or threatened responses may include, but are not limited to, purchasing and financing restrictions, withdrawal of financial intermediaries, boycotts or changes in consumer or purchaser preferences, sanctions, export and import controls, tariffs or cyberattacks on the Russian government, Russian companies or Russian individuals, including politicians. Any actions by Russia made in response to such sanctions or retaliatory measures could further impair the value and liquidity of Fund investments. Sanctions and other similar measures have resulted in defaults on debt obligations by certain corporate issuers and the Russian Federation that could lead to cross-defaults or cross-accelerations on other obligations of these issuers.

The Russian securities market is characterized by limited volume of trading, resulting in difficulty in obtaining accurate prices and trading. These issues can be magnified as a result of sanctions and other similar measures that may be imposed and the Russian government’s response. The Russian securities market, as compared to U.S. markets, has significant price volatility, less liquidity, a smaller market capitalization and a smaller number of traded securities. There may be little publicly available information about issuers. Settlement, clearing and registration of securities transactions are subject to risks. Prior to the implementation of the National Settlement Depository (“NSD”), a recognized central securities depository, there was no central registration system for equity share registration in Russia, and registration was carried out by either the issuers themselves or by registrars located throughout Russia. Title to Russian equities held through the NSD is now based on the records of the NSD and not the registrars. Although the implementation of the NSD has enhanced the efficiency and transparency of the Russian securities market, issues resulting in loss can still occur. In addition, sanctions by the European

Union against the NSD, as well as the potential for sanctions by other governments, could make it more difficult to conduct or confirm transactions involving Russian securities. Ownership of securities issued by Russian companies that are not held through depositories such as the NSD may be recorded by companies themselves and by registrars. In such cases, the risk is increased that the Fund could lose ownership rights through fraud, negligence or oversight. While applicable Russian regulations impose liability on registrars for losses resulting from their errors, it may be difficult for the Fund to enforce any rights it may have against the registrar or issuer of the securities in the event of loss of share registration. In addition, issuers and registrars are still prominent in the validation and approval of documentation requirements for corporate action processing in Russia. Because the documentation requirements and approval criteria vary between registrars and issuers, there remain unclear and inconsistent market standards in the Russian market with respect to the completion and submission of corporate action elections. In addition, sanctions or Russian countermeasures may prohibit or limit a Fund’s ability to participate in corporate actions, and therefore require the Fund to forego voting on or receiving funds that would otherwise be beneficial to the Fund. To the extent that the Fund suffers a loss relating to title or corporate actions relating to its portfolio securities, it may be difficult for the Fund to enforce its rights or otherwise remedy the loss. Russian securities laws may not recognize foreign nominee accounts held with a custodian bank, and therefore the custodian may be considered the ultimate owner of securities they hold for their clients. Adverse currency exchange rates are a risk and there may be a lack of available currency hedging instruments. Investments in Russia may be subject to the risk of nationalization or expropriation of assets. Oil, natural gas, metals, minerals and timber account for a significant portion of Russia’s exports, leaving the country vulnerable to swings in world prices and to sanctions or other actions that may be directed at the Russian economy as a whole or at Russian oil, natural gas, metals, minerals or timber industries.

High Yield Securities Risk [Member]

General Description of Registrant [Abstract]

Risk [Text Block]

High Yield Securities Risk

To the extent that the Fund invests in high yield securities and unrated securities of similar credit quality (commonly known as “high yield securities” or “junk bonds”), the Fund may be subject to greater levels of credit risk, call risk and liquidity risk than funds that do not invest in such securities, which could have a negative effect on the NAV and market price of the Fund’s Common Shares or Common Share dividends. These securities are considered predominantly speculative with respect to an issuer’s continuing ability to make principal and interest payments, and may be more volatile than other types of securities. An economic downturn or individual corporate developments could adversely affect the market for these securities and reduce the Fund’s ability to sell these securities at an advantageous time or price. The Fund may purchase

distressed securities that are in default or the issuers of which are in bankruptcy, which involve heightened risks.

High yield securities structured as zero-coupon bonds or pay-in-kind securities tend to be especially volatile as they are particularly sensitive to downward pricing pressures from rising interest rates or widening spreads and may require the Fund to make taxable distributions of imputed income without receiving the actual cash currency. Issuers of high yield securities may have the right to “call” or redeem the issue prior to maturity, which may result in the Fund having to reinvest the proceeds in other high yield securities or similar instruments that may pay lower interest rates. The Fund may also be subject to greater levels of liquidity risk than funds that do not invest in high yield securities. Consequently, transactions in high yield securities may involve greater costs than transactions in more actively traded securities. A lack of publicly-available information, irregular trading activity and wide bid/ask spreads among other factors, may, in certain circumstances, make high yield debt more difficult to sell at an advantageous time or price than other types of securities or instruments. These factors may result in the Fund being unable to realize full value for these securities and/or may result in the Fund not receiving the proceeds from a sale of a high yield security for an extended period after such sale, each of which could result in losses to the Fund. Because of the risks involved in investing in high yield securities, an investment in the Fund should be considered speculative.

In general, lower rated debt securities carry a greater degree of risk that the issuer will lose its ability to make interest and principal payments, which could have a negative effect on the Fund. Securities of below investment grade quality are regarded as having predominantly speculative characteristics with respect to capacity to pay interest and repay principal and are commonly referred to as “high yield” securities or “junk bonds.” High yield securities involve a greater risk of default and their prices are generally more volatile and sensitive to actual or perceived negative developments. Debt securities in the lowest investment grade category also may be considered to possess some speculative characteristics by certain rating agencies. The Fund may purchase stressed or distressed securities that are in default or the issuers of which are in bankruptcy, which involve heightened risks.

An economic downturn could severely affect the ability of issuers (particularly those that are highly leveraged) to service or repay their debt obligations. Lower-rated securities are generally less liquid than higher-rated securities, which may have an adverse effect on the Fund’s ability to dispose of them. For example, under adverse market or economic conditions, the secondary market for below investment grade securities could contract further, independent of any specific adverse changes in the condition of a particular issuer, and certain

securities in the Fund’s portfolio may become illiquid or less liquid. As a result, the Fund could find it more difficult to sell these securities or may be able to sell these securities only at prices lower than if such securities were widely traded. To the extent the Fund focuses on below investment grade debt obligations, PIMCO’s capabilities in analyzing credit quality and associated risks will be particularly important, and there can be no assurance that PIMCO will be successful in this regard. Due to the risks involved in investing in high yield securities, an investment in the Fund should be considered speculative.

The Fund’s credit quality policies apply only at the time a security is purchased, and the Fund is not required to dispose of a security in the event that a rating agency or PIMCO downgrades its assessment of the credit characteristics of a particular issue. In determining whether to retain or sell such a security, PIMCO may consider factors including, but not limited to, PIMCO’s assessment of the credit quality of the issuer of such security, the price at which such security could be sold and the rating, if any, assigned to such security by other rating agencies. Analysis of creditworthiness may be more complex for issuers of high yield securities than for issuers of higher quality debt securities.

Risk [Text Block]

Inflation/Deflation Risk

Inflation risk is the risk that the value of assets or income from the Fund’s investments will be worth less in the future as inflation decreases the value of payments at future dates. As inflation increases, the real value of the Fund’s portfolio could decline. Inflation has increased and it cannot be predicted when, if, or the degree to which it may decline. Deflation risk is the risk that prices throughout the economy decline over time. Deflation may have an adverse effect on the creditworthiness of issuers and may make issuer default more likely, which may result in a decline in the value of the Fund’s portfolio and Common Shares.

InflationIndexed Security Risk [Member]

General Description of Registrant [Abstract]

Risk [Text Block]

Inflation-Indexed Security Risk

Inflation-indexed debt securities are subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). In general, the value of an inflation-indexed security, including Treasury Inflation-Protected Securities (“TIPS”), tends to decrease when real interest rates increase and can increase when real interest rates decrease. Thus generally, during periods of rising inflation, the value of inflation-indexed securities will tend to increase and during periods of deflation, their value will tend to decrease. Interest payments on inflation-indexed securities are unpredictable and will fluctuate as the principal and interest are adjusted for inflation. There can be no assurance that the inflation index used (i.e., the Consumer Price Index (“CPI”)), which is calculated and published by a third-party, will accurately measure the real rate of inflation in the prices of goods and services. Increases in the principal value of TIPS

due to inflation are considered taxable ordinary income for the amount of the increase in the calendar year. Any increase in the principal amount of an inflation-indexed debt security will be considered taxable ordinary income, even though the Fund will not receive the principal until maturity. Additionally, a CPI swap can potentially lose value if the realized rate of inflation over the life of the swap is less than the fixed market implied inflation rate (fixed breakeven rate) that the investor agrees to pay at the initiation of the swap. With municipal inflation-indexed securities, the inflation adjustment is integrated into the coupon payment, which is federally tax exempt (and may be state tax exempt). For municipal inflation-indexed securities, there is no adjustment to the principal value. Because municipal inflation-indexed securities are a small component of the municipal bond market, they may be less liquid than conventional municipal bonds.

Issuer Risk [Member]

General Description of Registrant [Abstract]

Risk [Text Block]

Issuer Risk

The value of a security may decline for a number of reasons that directly relate to the issuer, such as management performance, major litigation, investigations or other controversies, changes in financial condition or credit rating, changes in government regulations affecting the issuer or its competitive environment and strategic initiatives such as mergers, acquisitions or dispositions and the market response to any such initiatives, financial leverage or reduced demand for the issuer’s goods or services, as well as the historical and prospective earnings of the issuer and the value of its assets. A change in the financial condition of a single issuer may affect securities markets as a whole. These risks can apply to the Common Shares issued by the Fund and to the issuers of securities and other instruments in which the Fund invests.

Leverage Risk [Member]

General Description of Registrant [Abstract]

Risk [Text Block]

Leverage Risk

The Fund’s use of leverage, if any, creates the opportunity for increased Common Share net income, but also creates special risks for Common Shareholders. To the extent used, there is no assurance that the Fund’s leveraging strategies will be successful. Leverage is a speculative technique that may expose the Fund to greater risk and increased costs. The Fund’s assets attributable to leverage, if any, will be invested in accordance with the Fund’s investment objectives and policies. Interest expense payable by the Fund with respect to derivatives and other forms of leverage, and dividends payable with respect to preferred shares outstanding, if any, will generally be based on shorter-term interest rates that would be periodically reset. So long as the Fund’s portfolio investments provide a higher rate of return (net of applicable Fund expenses) than the interest expenses and other costs to the Fund of such leverage, the investment of the proceeds thereof will generate more income than will be needed to pay the costs of the leverage. If so, and all other things being equal, the excess

may be used to pay higher dividends to Common Shareholders than if the Fund were not so leveraged. If, however, shorter-term interest rates rise relative to the rate of return on the Fund’s portfolio, the interest and other costs to the Fund of leverage could exceed the rate of return on the debt obligations and other investments held by the Fund, thereby reducing return to Common Shareholders. Leveraging transactions pursued by the Fund may increase its duration and sensitivity to interest rate movements. In addition, fees and expenses of any form of leverage used by the Fund will be borne entirely by the Common Shareholders (and not by preferred shareholders, if any) and will reduce the investment return of the Common Shares. Therefore, there can be no assurance that the Fund’s use of leverage will result in a higher yield on the Common Shares, and it may result in losses. In addition, any preferred shares issued by the Fund are expected to pay cumulative dividends, which may tend to increase leverage risk. Leverage creates several major types of risks for Common Shareholders, including:

∎  the likelihood of greater volatility of NAV and market price of Common Shares, and of the investment return to Common Shareholders, than a comparable portfolio without leverage;

∎  the possibility either that Common Share dividends will fall if the interest and other costs of leverage rise, or that dividends paid on Common Shares will fluctuate because such costs vary over time; and

∎  the effects of leverage in a declining market or a rising interest rate environment, as leverage is likely to cause a greater decline in the NAV of the Common Shares than if the Fund were not leveraged.

In addition, the counterparties to the Fund’s leveraging transactions and any preferred shareholders of the Fund will have priority of payment over the Fund’s Common Shareholders.

Reverse repurchase agreements involve the risks that the interest income earned on the investment of the proceeds will be less than the interest expense and Fund expenses associated with the repurchase agreement, that the market value of the securities sold by the Fund may decline below the price at which the Fund is obligated to repurchase such securities and that the securities may not be returned to the Fund. There is no assurance that reverse repurchase agreements can be successfully employed. Dollar roll transactions involve the risk that the market value of the securities the Fund is required to purchase may decline below the agreed upon repurchase price of those securities. Successful use of dollar rolls may depend upon the Investment Manager’s ability to correctly predict interest rates and prepayments. There is no assurance that dollar rolls can be successfully employed. In connection with reverse repurchase agreements and dollar rolls, the Fund will also be subject to counterparty risk with

respect to the purchaser of the securities. If the broker/dealer to whom the Fund sells securities becomes insolvent, the Fund’s right to purchase or repurchase securities may be restricted.

The Fund may engage in total return swaps, reverse repurchases, loans of portfolio securities, short sales and when-issued, delayed delivery and forward commitment transactions, credit default swaps, basis swaps and other swap agreements, purchases or sales of futures and forward contracts (including foreign currency exchange contracts), call and put options or other derivatives. The Fund’s use of such transactions gives rise to associated leverage risks described above, and may adversely affect the Fund’s income, distributions and total returns to Common Shareholders. To the extent that any offsetting positions do not behave in relation to one another as expected, the Fund may perform as if it is leveraged through use of these derivative strategies.

Any total return swaps, reverse repurchases, loans of portfolio securities, short sales and when-issued, delayed delivery and forward commitment transactions, credit default swaps, basis swaps and other swap agreements, purchases or sales of futures and forward contracts (including foreign currency exchange contracts), call and put options or other derivatives by the Fund or counterparties to the Fund’s other leveraging transactions, if any, would have seniority over the Fund’s Common Shares.

In addition to preferred shares, the Fund may engage in other transactions that may give rise to a form of leverage including, among others loans of portfolio securities, short sales and when-issued, delayed delivery and forward commitment transactions, credit default swaps, reverse repurchases, or other derivatives. The Fund’s use of such transactions gives rise to associated leverage risks described above, and may adversely affect the Fund’s income, distributions and total returns to Common Shareholders. The Fund may offset derivatives positions against one another or against other assets to manage effective market exposure resulting from derivatives in portfolio. To the extent that any offsetting positions do not behave in relation to one another as expected, the Fund may perform as if it is leveraged through use of these derivative strategies. See “Use of Leverage.”

The Fund is required to satisfy certain regulatory and rating agency asset coverage requirements in connection with its use of preferred shares. Accordingly, any decline in the net asset value of the Fund’s investments could result in the risk that the Fund will fail to meet its asset coverage requirements for any such preferred shares or the risk of the Preferred Shares being downgraded by a rating agency. In an extreme case, the Fund’s current investment income might not be sufficient to meet the dividend requirements on any preferred shares outstanding. In order to address these types of events, the Fund might

need to liquidate investments in order to fund a redemption of some or all of preferred shares. Liquidations at times of adverse economic conditions may result in a loss to the Fund. At other times, these liquidations may result in gain at the Fund level and thus in additional taxable distributions to Common Shareholders. See “Tax Matters” for more information. Any preferred shares of portfolio securities, short sales and when-issued, delayed delivery and forward commitment transactions, credit default swaps, reverse repurchases, or other derivatives by the Fund or counterparties to the Fund’s other leveraging transactions, if any, would have, seniority over the Fund’s Common Shares.

When the Fund issues preferred shares, the Fund pays (and the Common Shareholders bear) all costs and expenses relating to the issuance and ongoing maintenance of preferred shares. In addition, holders of any preferred shares issued by the Fund would have complete priority over Common Shareholders in the distribution of the Fund’s assets. Furthermore, preferred shareholders, voting separately as a single class, have the right to elect two members of the Board at all times and to elect a majority of the trustees in the event two full years’ dividends on the preferred shares are unpaid, and also have separate class voting rights on certain matters. Accordingly, preferred shareholders may have interests that differ from those of Common Shareholders, and may at times have disproportionate influence over the Fund’s affairs.

Because the fees received by the Investment Manager may increase depending on the types of leverage utilized by the Fund,1 the Investment Manager has a financial incentive for the Fund to use certain forms of leverage, which may create a conflict of interest between the Investment Manager, on the one hand, and the Common Shareholders, on the other hand.

Liquidity Risk [Member]

General Description of Registrant [Abstract]

Risk [Text Block]

Liquidity Risk

Liquidity risk exists when particular investments are difficult to purchase or sell. Illiquid investments are investments that the Fund reasonably expects cannot be sold or disposed of in current market conditions in seven calendar days or less without the sale or disposition significantly changing the market value of the investment. Illiquid investments may become harder to value, especially in changing markets. The Fund’s investments in illiquid investments may reduce the returns of the Fund because it may be unable to sell the illiquid investments at an advantageous time or price or possibly require the Fund to dispose of other investments at unfavorable times or prices in order to satisfy its obligations, which could prevent the Fund from taking advantage of other investment opportunities. Additionally, the market for certain investments may become illiquid under adverse market or economic conditions independent of any specific adverse changes in the conditions of a particular issuer. Bond

markets have consistently grown over the past three decades while the capacity for traditional dealer counterparties to engage in fixed income trading has not kept pace and in some cases has decreased. As a result, dealer inventories of corporate bonds, which provide a core indication of the ability of financial intermediaries to “make markets,” are at or near historic lows in relation to market size. Because market makers seek to provide stability to a market through their intermediary services, the significant reduction in dealer inventories could potentially lead to decreased liquidity and increased volatility in the fixed income markets. Such issues may be exacerbated during periods of economic uncertainty.

In such cases, the Fund, due to regulatory limitations on investments in illiquid investments and the difficulty in purchasing and selling such securities or instruments, may be unable to achieve its desired level of exposure to a certain sector. To the extent that the Fund’s principal investment strategies involve securities of companies with smaller market capitalizations, foreign (non-U.S.) securities, Rule 144A securities, illiquid sectors of fixed income securities, derivatives or securities with substantial market and/or credit risk, the Fund will tend to have the greatest exposure to liquidity risk.

Further, fixed income securities with longer durations until maturity face heightened levels of liquidity risk as compared to fixed income securities with shorter durations until maturity. The risks associated with illiquid instruments may be particularly acute in situations in which the Fund’s operations require cash (such as in connection with repurchase offers) and could result in the Fund borrowing to meet its short-term needs or incurring losses on the sale of illiquid instruments. It may also be the case that other market participants may be attempting to liquidate fixed income holdings at the same time as the Fund, causing increased supply in the market and contributing to liquidity risk and downward pricing pressure.

Liquidity risk also refers to the risk that the Fund may be required to hold additional cash or sell other investments in order to obtain cash to close out derivatives or meet the liquidity demands that derivatives can create to make payments of margin, collateral, or settlement payments to counterparties. The Fund may have to sell a security at a disadvantageous time or price to meet such obligations.

The current direction of governments and regulators may have the effect of reducing market liquidity, market resiliency and money supply, such as through higher rates, tighter financial regulations and proposals related to open-end fund liquidity that may prevent mutual funds and exchange-traded funds from participating in certain markets.

Loans and Other Indebtedness Loan Participations and Assignments Risk [Member]

General Description of Registrant [Abstract]

Risk [Text Block]

Loans and Other Indebtedness; Loan Participations and Assignments Risk

Loan interests may take the form of (i) direct interests acquired during a primary distribution or (ii) assignments of, novations of or participations in all or a portion of a loan acquired in secondary markets. In addition to credit risk and interest rate risk, the Fund’s exposure to loan interests may be subject to additional risks. For example, purchasers of loans and other forms of direct indebtedness depend primarily upon the creditworthiness of the borrower for payment of principal and interest. Loans are subject to the risk that scheduled interest or principal payments will not be made in a timely manner or at all, either of which may adversely affect the value of the loan. If the Fund does not receive scheduled interest or principal payments on such indebtedness, the Fund’s share price and yield could be adversely affected. Loans that are fully secured may offer the Fund more protection than an unsecured loan in the event of non-payment of scheduled interest or principal if the Fund is able to access and monetize the collateral. However, the collateral underlying a loan, if any, may be unavailable or insufficient to satisfy a borrower’s obligation. If the Fund becomes owner, whole or in part, of any collateral after a loan is foreclosed, the Fund may incur costs associated with owning and/or monetizing its ownership of the collateral.

Moreover, the purchaser of an assignment typically succeeds to all the rights and obligations under the loan agreement with the same rights and obligations as the assigning lender. Assignments may, however, be arranged through private negotiations between potential assignees and potential assignors, and the rights and obligations acquired by the purchaser of an assignment may differ from, and be more limited than, those held by the assigning lender.

Investments in loans through a purchase of a loan, loan origination or a direct assignment of a financial institution’s interests with respect to a loan may involve additional risks to the Fund. For example, if a loan is foreclosed, the Fund could become owner, in whole or in part, of any collateral, which could include, among other assets, real estate or other real or personal property, and would bear the costs and liabilities associated with owning and holding or disposing of the collateral. The purchaser of an assignment typically succeeds to all the rights and obligations under the loan agreement with the same rights and obligations as the assigning lender. Assignments may, however, be arranged through private negotiations between potential assignees and potential assignors, and the rights and obligations acquired by the purchaser of an assignment may differ from, and be more limited than, those held by the assigning lender.

In connection with purchasing loan participations, the Fund generally will have no right to enforce compliance by the borrower with the terms of the loan agreement relating to the loan, nor any rights of set-off against the borrower, and the Fund may not directly benefit from any collateral supporting the loan in which it has purchased the loan participation. As a result, the Fund will be subject to the credit risk of both the borrower and the lender that is selling the participation. In the event of the insolvency of the lender selling a participation, the Fund may be treated as a general creditor of the lender and may not benefit from any set-off between the lender and the borrower. Certain loan participations may be structured in a manner designed to prevent purchasers of participations from being subject to the credit risk of the lender, but even under such a structure, in the event of the lender’s insolvency, the lender’s servicing of the participation may be delayed and the assignability of the participation impaired.

The Fund may have difficulty disposing of loans and loan participations. Because there is no liquid market for many such investments, the Fund anticipates that such investments could be sold only to a limited number of institutional investors. The lack of a liquid secondary market may have an adverse impact on the value of such investments and the Fund’s ability to dispose of particular loans and loan participations when that would be desirable, including in response to a specific economic event such as a deterioration in the creditworthiness of the borrower. The lack of a liquid secondary market for loans and loan participations also may make it more difficult for the Fund to assign a value to these securities for purposes of valuing the Fund’s portfolio.

Investments in loans may include participations in bridge loans, which are loans taken out by borrowers for a short period (typically less than one year) pending arrangement of more permanent financing through, for example, the issuance of bonds, frequently high yield bonds issued for the purpose of acquisitions.

Investments in loans may include acquisitions of, or participation in, delayed funding loans and revolving credit facilities. These commitments may have the effect of requiring the Fund to increase its investment in a borrower at a time when it might not otherwise decide to do so (including at a time when the company’s financial condition makes it unlikely that such amounts will be repaid). Delayed funding loans and revolving credit facilities may be subject to restrictions on transfer, and only limited opportunities may exist to resell such instruments. As a result, a Fund may be unable to sell such investments at an opportune time or may have to resell them at less than fair market value. Further, the Fund may need to hold liquid assets in order to provide funding for these types of commitments, meaning the Fund may not be able to invest in other

attractive investments, or the Fund may need to liquidate existing assets in order to provide such funding.

To the extent the Fund invests in loans, including bank loans, the Fund may be subject to greater levels of credit risk, call risk, settlement risk and liquidity risk. These instruments are considered predominantly speculative with respect to an issuer’s continuing ability to make principal and interest payments and may be more volatile than other types of securities. The Fund may also be subject to greater levels of liquidity risk than funds that do not invest in loans. In addition, the loans in which the Fund invests may not be listed on any exchange and a secondary market for such loans may be comparatively illiquid relative to markets for other more liquid fixed income securities. Consequently, transactions in loans may involve greater costs than transactions in more actively traded securities. In connection with certain loan transactions, transaction costs that are borne by the Fund may include the expenses of third parties that are retained to assist with reviewing and conducting diligence, negotiating, structuring and servicing a loan transaction, and/or providing other services in connection therewith. Furthermore, the Fund may incur such costs in connection with loan transactions that are pursued by the Fund but not ultimately consummated (so-called “broken deal costs”).

Restrictions on transfers in loan agreements, a lack of publicly available information, irregular trading activity and wide bid/ask spreads, among other factors, may, in certain circumstances, make loans more difficult to sell at an advantageous time or price than other types of securities or instruments. These factors may result in the Fund being unable to realize full value for the loans and/or may result in the Fund not receiving the proceeds from a sale of a loan for an extended period after such sale, each of which could result in losses to the Fund. Some loans may have extended trade settlement periods, including settlement periods of greater than seven days, which may result in cash not being immediately available to the Fund. If an issuer of a loan prepays or redeems the loan prior to maturity, the Fund may have to reinvest the proceeds in other loans or similar instruments that may pay lower interest rates. Because of the risks involved in investing in loans, an investment in the Fund should be considered speculative.

The Fund’s investments in subordinated and unsecured loans generally are subject to similar risks as those associated with investments in secured loans. Subordinated or unsecured loans are lower in priority of payment to secured loans and are subject to the additional risk that the cash flow of the borrower and property securing the loan or debt, if any, may be insufficient to meet scheduled payments after giving effect to the senior secured obligations of the borrower. This risk is generally higher for subordinated unsecured loans or debt, which are not backed by a security interest in any specific collateral. Subordinated and unsecured loans generally have greater price

volatility than secured loans and may be less liquid. There is also a possibility that originators will not be able to sell participations in subordinated or unsecured loans, which would create greater credit risk exposure for the holders of such loans. Subordinate and unsecured loans share the same risks as other below investment grade securities.

There may be less readily available information about most loans and the underlying borrowers than is the case for many other types of securities. Loans may be issued by borrowers that are not subject to SEC reporting requirements and therefore may not be required to file reports with the SEC or may file reports that are not required to comply with SEC form requirements. In addition, such borrowers may be subject to a less stringent liability disclosure regime than companies subject to SEC reporting requirements. Loans may not be considered “securities,” and purchasers, such as the Fund, therefore may not be entitled to rely on the anti-fraud protections of the federal securities laws. Because there is limited public information available regarding loan investments, the Fund is particularly dependent on the analytical abilities of the Fund’s portfolio managers.

Economic exposure to loan interests through the use of derivative transactions may involve greater risks than if the Fund had invested in the loan interest directly during a primary distribution or through assignments of, novations of or participations in a loan acquired in secondary markets since, in addition to the risks described above, certain derivative transactions may be subject to leverage risk and greater illiquidity risk, counterparty risk, valuation risk and other risks.

Management Risk [Member]

General Description of Registrant [Abstract]

Risk [Text Block]

Management Risk

The Fund is subject to management risk because it is an actively managed investment portfolio. PIMCO and each individual portfolio manager will apply investment techniques and risk analysis in making investment decisions for the Fund, but there can be no guarantee that these decisions will produce the desired results. Certain securities or other instruments in which the Fund seeks to invest may not be available in the quantities desired. In addition, regulatory restrictions, actual or potential conflicts of interest or other considerations may cause PIMCO to restrict or prohibit participation in certain investments. In such circumstances, PIMCO or the individual portfolio managers may determine to purchase other securities or instruments as substitutes. Such substitute securities or instruments may not perform as intended, which could result in losses to the Fund. To the extent the Fund employs strategies targeting perceived pricing inefficiencies, arbitrage strategies or similar strategies, it is subject to the risk that the pricing or valuation of the securities and instruments involved in such strategies may change unexpectedly, which may result in reduced returns or losses to the Fund. Additionally, actual or potential conflicts of interest, legislative, regulatory, or tax restrictions, policies or developments may affect the investment techniques

available to PIMCO and each individual portfolio manager in connection with managing the Fund and may also adversely affect the ability of the Fund to achieve its investment objectives. There also can be no assurance that all of the personnel of PIMCO will continue to be associated with PIMCO for any length of time. The loss of services of one or more key employees of PIMCO could have an adverse impact on the Fund’s ability to realize its investment objectives.

In addition, the Fund may rely on various third-party sources to calculate its NAV. As a result, the Fund is subject to certain operational risks associated with reliance on service providers and service providers’ data sources. In particular, errors or systems failures and other technological issues may adversely impact the Fund’s calculations of its NAV, and such NAV calculation issues may result in inaccurately calculated NAVs, delays in NAV calculation and/or the inability to calculate NAVs over extended periods. The Fund may be unable to recover any losses associated with such failures.

Market Discount Risk

The price of the Fund’s Common Shares will fluctuate with market conditions and other factors. If you sell your Common Shares, the price received may be more or less than your original investment. The Common Shares are designed for long-term investors and should not be treated as trading vehicles. Shares of closed-end management investment companies frequently trade at a discount from their NAV.

Market Disruptions Risk [Member]

General Description of Registrant [Abstract]

Risk [Text Block]

Market Disruptions Risk

The Fund is subject to investment and operational risks associated with financial, economic and other global market developments and disruptions, including those arising from war, terrorism, market manipulation, government interventions, defaults and shutdowns, political changes or diplomatic developments, public health emergencies (such as the spread of infectious diseases, pandemics and epidemics) and natural/environmental disasters, which can all negatively impact the securities markets, interest rates, auctions, secondary trading, ratings, credit risk, inflation, deflation, other factors relating to the Fund’s investments or the Investment Manager’s operations and the value of an investment in the Fund, its distributions and its returns. These events can also impair the technology and other operational systems upon which the Fund’s service providers, including PIMCO as the Fund’s investment adviser, rely, and could otherwise disrupt the Fund’s service providers’ ability to fulfill their obligations to the Fund. Furthermore, events involving limited liquidity, defaults, non-performance or other adverse developments that affect financial institutions or the financial services industry generally, or concerns or rumors about any events of these kinds or other similar risks, have in the past and may in the future lead to market-wide liquidity problems.

Market Risk [Member]

General Description of Registrant [Abstract]

Risk [Text Block]

Market Risk

The market price of securities owned by the Fund may go up or down, sometimes rapidly or unpredictably. Securities may decline in value due to factors affecting securities markets generally or particular industries or issuers represented in the securities markets. The value of a security may decline due to general market conditions that are not specifically related to a particular company, such as real or perceived adverse economic conditions, changes in the general outlook for corporate earnings, changes in interest or currency rates, adverse changes to credit markets or adverse investor sentiment generally. The value of a security may also decline due to factors that affect a particular industry or industries, such as labor shortages or increased production costs and competitive conditions within an industry. During a general downturn in the securities markets, multiple asset classes may decline in value simultaneously. Equity securities generally have greater price volatility than fixed income securities. Credit ratings downgrades may also negatively affect securities held by the Fund. Even when markets perform well, there is no assurance that the investments held by the Fund will increase in value along with the broader market.

In addition, market risk includes the risk that geopolitical and other events will disrupt the economy on a national or global level. For instance, war, terrorism, social unrest, recessions, supply chain disruptions, market manipulation, government defaults, government shutdowns, political changes, diplomatic developments or the imposition of sanctions and other similar measures, public health emergencies (such as the spread of infectious diseases, pandemics and epidemics) and natural/environmental disasters can all negatively impact the securities markets, which could cause the Fund to lose value. These events could reduce consumer demand or economic output, result in market closures, changes in interest rates, inflation/deflation, travel restrictions or quarantines, and significantly adversely impact the economy. The current contentious domestic political environment, as well as political and diplomatic events within the United States and abroad, such as presidential elections in the U.S. or abroad or the U.S. government’s inability at times to agree on a long-term budget and deficit reduction plan, has in the past resulted, and may in the future result, in a government shutdown or otherwise adversely affect the U.S. regulatory landscape, the general market environment and/or investor sentiment, which could have an adverse impact on the Fund’s investments and operations. Additional and/or prolonged U.S. federal government shutdowns may affect investor and consumer confidence and may adversely impact financial markets and the broader economy, perhaps suddenly and to a significant degree. Governmental and quasi-governmental authorities and regulators throughout the world have previously responded to serious economic disruptions with a variety of significant fiscal and monetary policy changes, including but not limited to, direct capital infusions into

companies, new monetary programs and dramatically lower interest rates. An unexpected or sudden reversal of these policies, or the ineffectiveness of these policies, could increase volatility in securities markets, which could adversely affect the Fund’s investments. Any market disruptions could also prevent the Fund from executing advantageous investment decisions in a timely manner. Funds that have focused their investments in a region enduring geopolitical market disruption will face higher risks of loss. Thus, investors should closely monitor current market conditions to determine whether the Fund meets their individual financial needs and tolerance for risk.

Recently, there have been inflationary price movements. As such, fixed income securities markets may experience heightened levels of interest rate, volatility and liquidity risk. As discussed more under “Interest Rate Risk,” the Federal Reserve has begun to raise interest rates from historically low levels and has signaled an intention to continue to do so. Any additional interest rate increases in the future could cause the value of any Fund, such as the Fund, that invests in fixed income securities to decrease.

Although interest rates have significantly increased since 2022 through the date of this report, the prices of real estate-related assets generally have not decreased as much as may be expected based on historical correlations between interest rates and prices of real estate-related assets. This presents an increased risk of a correction or severe downturn in real estate-related asset prices, which could adversely impact the value of other investments as well (such as loans, securitized debt and other fixed income securities). This risk is particularly present with respect to commercial real estate-related asset prices, and the value of other investments with a connection to the commercial real estate sector. As examples of the current risks faced by real estate-related assets: tenant vacancy rates, tenant turnover and tenant concentration have increased; owners of real estate have faced headwinds, delinquencies and difficulties in collecting rents and other payments (which increases the risk of owners being unable to pay or otherwise defaulting on their own borrowings and obligations); property values have declined; inflation, upkeep costs and other expenses have increased; and rents have declined for many properties.

Exchanges and securities markets may close early, close late or issue trading halts on specific securities, which may result in, among other things, the Fund being unable to buy or sell certain securities or financial instruments at an advantageous time or accurately price its portfolio investments.

MortgageRelated and Other AssetBacked Instruments Risk [Member]

General Description of Registrant [Abstract]

Risk [Text Block]

Mortgage-Related and Other Asset-Backed Instruments Risk

The mortgage-related assets in which the Fund may invest include, but are not limited to, any security, instrument or other asset that is

related to U.S. or non-U.S. mortgages, including those issued by private originators or issuers, or issued or guaranteed as to principal or interest by the U.S. government or its agencies or instrumentalities or by non-U.S. governments or authorities, such as, without limitation, assets representing interests in, collateralized or backed by, or whose values are determined in whole or in part by reference to any number of mortgages or pools of mortgages or the payment experience of such mortgages or pools of mortgages, including REMICs, which could include Re-REMICs, mortgage pass-through securities, inverse floaters, CMOs, CLOs, multiclass pass-through securities, private mortgage pass-through securities, stripped mortgage securities (generally interest-only and principal-only securities), mortgage-related asset backed securities and mortgage-related loans (including through participations, assignments, originations and whole loans), including commercial and residential mortgage loans. Exposures to mortgage-related assets through derivatives or other financial instruments will be considered investments in mortgage-related assets.

The Fund may also invest in other types of ABS, including CDOs, CBOs and CLOs and other similarly structured securities.

Mortgage-related and other asset-backed instruments represent interests in “pools” of mortgages or other assets such as consumer loans or receivables held in trust and often involve risks that are different from or possibly more acute than risks associated with other types of debt instruments. Generally, rising interest rates tend to extend the duration of fixed rate mortgage-related assets, making them more sensitive to changes in interest rates. Compared to other fixed income investments with similar maturity and credit, mortgage-related securities may increase in value to a lesser extent when interest rates decline and may decline in value to a similar or greater extent when interest rates rise. As a result, in a period of rising interest rates, the Fund may exhibit additional volatility since individual mortgage holders are less likely to exercise prepayment options, thereby putting additional downward pressure on the value of these securities and potentially causing the Fund to lose money. This is known as extension risk. Mortgage-backed securities can be highly sensitive to rising interest rates, such that even small movements can cause the Fund to lose value. Mortgage-backed securities, and in particular those not backed by a government guarantee, are subject to credit risk. When interest rates decline, borrowers may pay off their mortgages sooner than expected. This can reduce the returns of the Fund because the Fund may have to reinvest that money at the lower prevailing interest rates. The Fund’s investments in other asset-backed instruments are subject to risks similar to those associated with mortgage-related assets, as well as additional risks associated with the nature of the assets and the servicing of those assets. Payment of principal and

interest on asset-backed instruments may be largely dependent upon the cash flows generated by the assets backing the instruments, and asset-backed instruments may not have the benefit of any security interest in the related assets.

Subordinate mortgage-backed or asset-backed instruments are paid interest only to the extent that there are funds available to make payments. To the extent the collateral pool includes a large percentage of delinquent loans, there is a risk that interest payments on subordinate mortgage-backed or asset-backed instruments will not be fully paid.

There are multiple tranches of mortgage-backed and asset-backed instruments, offering investors various maturity and credit risk characteristics. Tranches are categorized as senior, mezzanine, and subordinated/equity or “first loss,” according to their degree of risk. The most senior tranche of a mortgage-backed or asset-backed instrument has the greatest collateralization and pays the lowest interest rate. If there are defaults or the collateral otherwise underperforms, scheduled payments to senior tranches take precedence over those of mezzanine tranches, and scheduled payments to mezzanine tranches take precedence over those to subordinated/equity tranches. Lower tranches represent lower degrees of credit quality and pay higher interest rates intended to compensate for the attendant risks. The return on the lower tranches is especially sensitive to the rate of defaults in the collateral pool. The lowest tranche (i.e., the “equity” or “residual” tranche) specifically receives the residual interest payments (i.e., money that is left over after the higher tranches have been paid and expenses of the issuing entities have been paid) rather than a fixed interest rate. The Fund may also invest in the residual or equity tranches of mortgage-related and other asset-backed instruments, which may be referred to as subordinate mortgage-backed or asset-backed instruments and interest-only mortgage-backed or asset-backed instruments. The Fund expects that investments in subordinate mortgage-backed and other asset-backed instruments will be subject to risks arising from delinquencies and foreclosures, thereby exposing its investment portfolio to potential losses. The Fund expects that investments in the lowest tranche of or subordinate mortgage-backed and other asset-backed instruments will be subject to the greatest risks of losing part or all of their values, which could arise from delinquencies and foreclosures, thereby exposing the Fund’s investment portfolio to potential losses. Subordinate securities of mortgage-backed and other asset-backed instruments are also subject to greater credit risk than those mortgage-backed or other asset-backed instruments that are more highly rated.

The mortgage markets in the United States and in various foreign countries have experienced extreme difficulties in the past that

adversely affected the performance and market value of certain of the Fund’s mortgage-related investments. Delinquencies and losses on residential and commercial mortgage loans (especially subprime and second-lien mortgage loans) may increase, and a decline in or flattening of housing and other real property values may exacerbate such delinquencies and losses. In addition, reduced investor demand for mortgage loans and mortgage-related securities and increased investor yield requirements have caused limited liquidity in the secondary market for mortgage-related securities, which can adversely affect the market value of mortgage-related securities. It is possible that such limited liquidity in such secondary markets could continue or worsen.

With respect to risk retention tranches (i.e., eligible residual interests initially held by the sponsors of CMBS and other eligible securitizations pursuant to the U.S. Risk Retention Rules), a third-party purchaser, such as the Fund, must hold its retained interest, unhedged, for at least five year following the closing of the CMBS transaction, after which it is entitled to transfer its interest in the securitization to another person that meets the requirements for a third-party purchaser. Even after the required holding period has expired, due to the generally illiquid nature of such investments, no assurance can be given as to what, if any, exit strategies will ultimately be available for any given position.

In addition, there is limited guidance on the application of the Final U.S. Risk Retention Rules to specific securitization structures. There can be no assurance that the applicable federal agencies charged with the implementation of the Final U.S. Risk Retention Rules (the FDIC, the Comptroller of the Currency, the Federal Reserve Board, the SEC, the Department of Housing and Urban Development, and the Federal Housing Finance Agency) could not take positions in the future that differ from the interpretation of such rules taken or embodied in such securitizations, or that the Final U.S. Risk Retention Rules will not change.

Furthermore, in situations where the Fund invests in risk retention tranches of securitizations structured by third parties, the Fund may be required to execute one or more letters or other agreements, the exact form and nature of which will vary (each, a “Risk Retention Agreement”) under which it will make certain undertakings designed to ensure such securitization complies with the U.S. Risk Retention Rules. Such Risk Retention Agreements may include a variety of representations, warranties, covenants and other indemnities, each of which may run to various transaction parties. If the Fund breaches any undertakings in any Risk Retention Agreement, it will be exposed to claims by the other parties thereto, including for any losses incurred as a result of such breach, which could be significant and exceed the value of the Fund’s investments.

MortgageRelated Derivative Instruments Risk [Member]

Risk [Text Block]

Mortgage-Related Derivative Instruments Risk

The Fund may engage in derivative transactions related to mortgage-backed securities, including purchasing and selling exchange-listed and OTC put and call options, futures and forwards on mortgages and mortgage-backed securities. The Fund may also invest in mortgage-backed securities credit default swaps, which include swaps the reference obligation for which is a mortgage-backed security or related index, such as the CMBX Index (a tradeable index referencing a basket of commercial mortgage-backed securities), the TRX Index (a tradeable index referencing total return swaps based on commercial mortgage-backed securities) or the ABX (a tradeable index referencing a basket of sub-prime mortgage-backed securities). The Fund may invest in newly developed mortgage related derivatives that may hereafter become available.

Derivative mortgage-backed securities (such as principal-only (“POs”), interest-only (“IOs”) or inverse floating rate securities) are particularly exposed to call and extension risks. Small changes in mortgage prepayments can significantly impact the cash flows and the market value of these derivative instruments. In general, the risk of faster than anticipated prepayments adversely affects IOs, super floaters and premium priced mortgage-backed securities. The risk of slower than anticipated prepayments generally affects POs, floating-rate securities subject to interest rate caps, support tranches and discount priced mortgage-backed securities. In addition, particular derivative instruments may be leveraged such that their exposure (i.e., price sensitivity) to interest rate and/or prepayment risk is magnified.

Mortgage-related derivative instruments involve risks associated with mortgage-related and other asset-backed instruments, privately-issued mortgage-related securities, the mortgage market, the real estate industry, derivatives and credit default swaps.

Operational Risk

An investment in the Fund, like any fund, can involve operational risks arising from factors such as processing errors, human errors, inadequate or failed internal or external processes, failures in systems and technology, changes in personnel and errors caused by third-party service providers. The occurrence of any of these failures, errors or breaches could result in a loss of information, regulatory scrutiny, reputational damage or other events, any of which could have a material adverse effect on the Fund. While the Fund seeks to minimize such events through controls and oversight, there may still be failures that could cause losses to the Fund.

Other Investment Companies Risk [Member]

Other Investment Companies Risk

When investing in an investment company, the Fund will generally bear its ratable share of that investment company’s expenses and would remain subject to payment of the Fund’s management fees and other expenses with respect to assets so invested. Common Shareholders

would therefore be subject to duplicative expenses to the extent the Fund invests in other investment companies. In addition, the securities of other investment companies may also be leveraged and will therefore be subject to same leverage risks.

Platform Risk [Member]

General Description of Registrant [Abstract]

Risk [Text Block]

Platform Risk

The Alt Lending ABS in which the Fund may invest are typically not listed on any securities exchange and not registered under the Securities Act. In addition, the Fund anticipates that these instruments may only be sold to a limited number of investors and may have a limited or non-existent secondary market. Accordingly, the Fund currently expects that certain of the investments it may make in Alt Lending ABS will face heightened levels of liquidity risk. Although currently there is generally no reliable, active secondary market for certain Alt Lending ABS, a secondary market for these Alt Lending ABS may develop. If the Fund purchases Alt Lending ABS on an alternative lending platform, the Fund will have the right to receive principal and interest payments due on loans underlying the Alt Lending ABS only if the platform servicing the loans receives the borrower’s payments on such loans and passes such payments through to the Fund. If a borrower is unable or fails to make payments on a loan for any reason, the Fund may be greatly limited in its ability to recover any outstanding principal or interest due, as (among other reasons) the Fund may not have direct recourse against the borrower or may otherwise be limited in its ability to directly enforce its rights under the loan, whether through the borrower or the platform through which such loan was originated, the loan may be unsecured or under-collateralized and/or it may be impracticable to commence a legal proceeding against the defaulting borrower.

The Fund may have limited knowledge about the underlying loans and is dependent upon the platform for information regarding underlying loans. Although PIMCO may conduct diligence on the platforms, the Fund generally does not have the ability to independently verify the information provided by the platforms, other than payment information regarding loans underlying the Alt Lending ABS owned by the Fund, which the Fund observes directly as payments are received. With respect to Alt Lending ABS that the Fund purchases in the secondary market (i.e., not directly from an alternative lending platform), the Fund may not perform the same level of diligence on such platform or at all. The Fund may not review the particular characteristics of the loans collateralizing an Alt Lending ABS, but rather negotiate in advance with platforms the general criteria of the underlying loans. As a result, the Fund is dependent on the platforms’ ability to collect, verify and provide information to the Fund about each loan and borrower.

The Fund relies on the borrower’s credit information, which is provided by the platforms. However, such information may be out of date,

incomplete or inaccurate and may, therefore, not accurately reflect the borrower’s actual creditworthiness. Platforms may not have an obligation to update borrower information, and, therefore, the Fund may not be aware of any impairment in a borrower’s creditworthiness subsequent to the making of a particular loan. The platforms’ credit decisions and scoring models may be based on algorithms that could potentially contain programming or other errors or prove to be ineffective or otherwise flawed. This could adversely affect loan pricing data and approval processes and could cause loans to be mispriced or misclassified, which could ultimately have a negative impact on the Fund’s performance.

In addition, the underlying loans, in some cases, may be affected by the success of the platforms through which they are facilitated.

Therefore, disruptions in the businesses of such platforms may also negatively impact the value of the Fund’s investments. In addition, disruption in the business of a platform could limit or eliminate the ability of the Fund to invest in loans originated by that platform, and therefore the Fund could lose some or all of the benefit of its diligence effort with respect to that platform.

Platforms are for-profit businesses that, as a general matter, generate revenue by collecting fees on funded loans from borrowers and by assessing a loan servicing fee on investors, which may be a fixed annual amount or a percentage of the loan or amounts collected. This business could be disrupted in multiple ways; for example, a platform could file for bankruptcy or a platform might suffer reputational harm from negative publicity about the platform or alternative lending more generally and the loss of investor confidence in the event that a loan facilitated through the platform is not repaid and the investor loses money on its investment. Many platforms and/or their affiliates have incurred operating losses since their inception and may continue to incur net losses in the future, particularly as their businesses grow and they incur additional operating expenses. Platforms may also be forced to defend legal action taken by regulators or governmental bodies. Alternative lending is a newer industry operating in an evolving legal environment. Platforms may be subject to risk of litigation alleging violations of law and/or regulations, including, for example, consumer protection laws, whether in the U.S. or in foreign jurisdictions. Platforms may be unsuccessful in defending against such lawsuits or other actions and, in addition to the costs incurred in fighting any such actions, platforms may be required to pay money in connection with the judgments, settlements or fines or may be forced to modify the terms of its borrower loans, which could cause the platform to realize a loss or receive a lower return on a loan than originally anticipated. Platforms may also be parties to litigation or other legal action in an attempt to protect or enforce their rights or those of affiliates, including intellectual property rights, and may incur similar costs in

connection with any such efforts. The Fund’s investments in Alt Lending ABS may expose the Fund to the credit risk of the issuer. Generally, such instruments are unsecured obligations of the issuer; an issuer that becomes subject to bankruptcy proceedings may be unable to make full and timely payments on its obligations to the Fund, even if the payments on the underlying loan or loans continue to be made timely and in full. In addition, when the Fund owns Alt Lending ABS, the Fund and its custodian generally does not have a contractual relationship with, or personally identifiable information regarding, individual borrowers, so the Fund will not be able to enforce underlying loans directly against borrowers and may not be able to appoint an alternative servicing agent in the event that a platform or third-party servicer, as applicable, ceases to service the underlying loans. Therefore, the Fund is more dependent on the platform for servicing than if the Fund had owned whole loans through the platform. Where such interests are secured, the Fund relies on the platform to perfect the Fund’s security interest. In addition, there may be a delay between the time the Fund commits to purchase an instrument issued by a platform, its affiliate or a special purpose entity sponsored by the platform or its affiliate and the issuance of such instrument and, during such delay, the funds committed to such an investment will not earn interest on the investment nor will they be available for investment in other alternative lending-related instruments, which will reduce the effective rate of return on the investment. The Fund’s investments in Alt Lending ABS may be illiquid.

Portfolio Turnover Risk [Member]

General Description of Registrant [Abstract]

Risk [Text Block]

Portfolio Turnover Risk

The Investment Manager manages the Fund without regard generally to restrictions on portfolio turnover. The use of futures contracts and other derivative instruments with relatively short maturities may tend to exaggerate the portfolio turnover rate for the Fund. Trading in fixed income securities does not generally involve the payment of brokerage commissions but does involve indirect transaction costs. The use of futures contracts and other derivative instruments may involve the payment of commissions to futures commission merchants or other intermediaries. Higher portfolio turnover involves correspondingly greater expenses to the Fund, including brokerage commissions or dealer mark-ups and other transaction costs on the sale of securities and reinvestments in other securities. The higher the rate of portfolio turnover of the Fund, the higher these transaction costs borne by the Fund generally will be. Such sales may result in realization of taxable capital gains (including short-term capital gains, which are generally taxed to shareholders at ordinary income tax rates when distributed net of short-term capital losses and net long-term capital losses) and may adversely impact the Fund’s after-tax returns.

Potential Conflicts of Interest Risk — Allocation of Investment Opportunities

The Investment Manager and its affiliates are involved worldwide with a broad spectrum of financial services and asset management activities and may engage in the ordinary course of business in activities in which their interests or the interests of their clients may conflict with those of the Fund. The Investment Manager may provide investment management services to other funds and discretionary managed accounts that follow an investment program similar to that of the Fund. Subject to the requirements of the 1940 Act, the Investment Manager intends to engage in such activities and may receive compensation from third parties for its services. The results of the Fund’s investment activities may differ from those of the Fund’s affiliates, or another account managed by the Investment Manager or its affiliates, and it is possible that the Fund could sustain losses during periods in which one or more of the Fund’s affiliates and/or other accounts managed by the Investment Manager or its affiliates, including proprietary accounts, achieve profits on their trading.

Preferred Securities Risk [Member]

General Description of Registrant [Abstract]

Risk [Text Block]

Preferred Securities Risk

In addition to equity securities risk, credit risk and possibly high yield risk, investment in preferred securities involves certain other risks. Certain preferred securities contain provisions that allow an issuer under certain conditions to skip or defer distributions. If the Fund owns a preferred security that is deferring its distribution, the Fund may be required to include the amount of the deferred distribution in its taxable income for tax purposes although it does not currently receive such amount in cash. In order to receive the special treatment accorded to regulated investment companies and their shareholders under the Internal Revenue Code of 1986, as amended (the “Code”) and to avoid U.S. federal income and/or excise taxes at the Fund level, the Fund may be required to distribute this income to shareholders in the tax year in which the income is recognized (without a corresponding receipt of cash). Therefore, the Fund may be required to pay out as an income distribution in any such tax year an amount greater than the total amount of cash income the Fund actually received and to sell portfolio securities, including at potentially disadvantageous times or prices, to obtain cash needed for these income distributions. Preferred securities often are subject to legal provisions that allow for redemption in the event of certain tax or legal changes or at the issuer’s call. In the event of redemption, the Fund may not be able to reinvest the proceeds at comparable rates of return. Preferred securities are subordinated to bonds and other debt securities in an issuer’s capital structure in terms of priority for corporate income and liquidation payments, and therefore will be subject to greater credit risk than those debt securities. Preferred securities may trade less frequently and in a more limited volume and may be subject to more abrupt or erratic price movements than many other securities.

Additional Risks Associated with the Funds Preferred Shares [Member]

General Description of Registrant [Abstract]

Risk [Text Block]

Additional Risks Associated with the Fund’s Preferred Shares

Although the Fund’s ARPS ordinarily would pay dividends at rates set at periodic auctions, the weekly auctions for the ARPS (and auctions for similar preferred shares issued by closed-end funds in the U.S.) have failed since 2008. The dividend rates on the ARPS since that time have been paid, and the Fund expects that they will continue to be paid for the foreseeable future, at the “maximum applicable rate” under the Fund’s Bylaws (i.e., the greater of a multiple of or a spread plus a reference rate). An increase in market interest rates generally, therefore, could increase substantially the dividend rate required to be paid by the Fund to the holders of ARPS, which would increase the costs associated with the Fund’s leverage and reduce the Fund’s net income available for distribution to Common Shareholders. In addition, the multiple or spread used to calculate the maximum applicable rate is based in part on the credit rating assigned to the ARPS by the applicable rating agency(ies), with the multiple or spread generally increasing as the rating declines. The Fund’s ARPS rating has previously been downgraded and the ARPS could be subject to further ratings downgrades in the future, possibly resulting in further increases to the maximum applicable rate.

Therefore, it is possible that a substantial rise in market interest rates and/or further ratings downgrades of the ARPS could, by reducing income available for distribution to the Common Shareholders and otherwise detracting from the Fund’s investment performance, make the Fund’s continued use of Preferred Shares for leverage purposes less attractive than such use is currently considered to be. In such case, the Fund may elect to redeem some or all of the Preferred Shares outstanding, which may require it to dispose of investments at inopportune times and to incur losses on such dispositions. Such dispositions may adversely affect the Fund’s investment performance generally, and the resultant loss of leverage may materially and adversely affect the Fund’s investment returns to Common Shareholders. The Fund has previously been required to redeem a portion of its ARPS due to market dislocations that caused the value of the Fund’s portfolio securities and related asset coverage to decline and could be required to do so again in the future.

The Fund is also subject to certain asset coverage tests associated with the rating agencies that rate the ARPS. Failure by the Fund to maintain the asset coverages (or to cure such failure in a timely manner) may require the Fund to redeem ARPS. Failure to satisfy ratings agency asset coverage tests or other guidelines could also result in the applicable ratings agency downgrading its then-current ratings on the ARPS, as described above. Moreover, the rating agency guidelines impose restrictions or limitations on the Fund’s use of certain financial instruments or investment techniques that the Fund might otherwise utilize in order to achieve its investment objective, which may adversely affect the Fund’s investment performance. Rating agency

guidelines may be modified by the rating agencies in the future and such modifications may make such guidelines substantially more restrictive or otherwise result in downgrades, which could further negatively affect the Fund’s investment performance.

As discussed further in “Notes to Financial Statements — Auction-Rate Preferred Shares”, on December 4, 2020, Fitch published revised ratings criteria relating to closed-end fund obligations, including preferred shares, which effectively result in a rating cap of “A” for the Fund. Following the close of business on April 30, 2021, Fitch downgraded its rating of the Fund’s ARPS from “AA” to “A” pursuant to the revised ratings methodology and related new rating caps. With respect to PIMCO Corporate & Income Strategy Fund, under the Fund’s Bylaws, the April 2021 Fitch downgrade resulted in an increase in the multiple used to calculate the maximum applicable rate from 150% to 160%, thereby increasing the dividend rate payable to the Fund’s ARPS holders and increasing the expenses to the Common Shareholders associated with the Fund’s leverage. In December 2022, Moody’s downgraded its rating of the PCN ARPS, PFL ARPS and PFN ARPs from “Aa3” to “A1,” stating that the downgrades occurred because of, among other matters, trends in each respective Fund’s risk-adjusted asset coverage metrics and the evolution of its sector exposures. With respect to each of PIMCO Income Strategy Fund and PIMCO Income Strategy Fund II, under each Fund’s Bylaws, the April 2021 Fitch downgrade resulted in an increase in the dividend rate multiplier from 1.50 to 2.00, which could increase the dividend rate payable to each Fund’s ARPS holders should the maximum dividend rate be determined via the multiplier in lieu of the spread noted above (the maximum dividend rate is based on the greater of a multiple of or a spread plus a reference rate) and, thereby, increase the expenses to Common Shareholders associated with the Fund’s leverage.

Privacy and Data Security Risk [Member]

General Description of Registrant [Abstract]

Risk [Text Block]

Privacy and Data Security Risk

The Gramm-Leach-Bliley Act (“GLBA”) and other laws limit the disclosure of certain non-public personal information about a consumer to non- affiliated third parties and require financial institutions to disclose certain privacy policies and practices with respect to information sharing with both affiliates and non- affiliated third parties. Many states and a number of non-U.S. jurisdictions have enacted privacy and data security laws requiring safeguards on the privacy and security of consumers’ personally identifiable information. Other laws deal with obligations to safeguard and dispose of private information in a manner designed to avoid its dissemination. Privacy rules adopted by the U.S. Federal Trade Commission and SEC implement GLBA and other requirements and govern the disclosure of consumer financial information by certain financial institutions, ranging from banks to private investment funds. U.S. platforms following certain models generally are required to have privacy policies that conform to these GLBA and other requirements. In addition, such

platforms typically have policies and procedures intended to maintain platform participants’ personal information securely and dispose of it properly.

The Fund generally does not intend to obtain or hold borrowers’ non-public personal information, and the Fund has implemented procedures designed to prevent the disclosure of borrowers’ non-public personal information to the Fund. However, service providers to the Fund, or its direct or indirect fully-owned subsidiaries, including their custodians and the platforms acting as loan servicers for the Fund or its direct or indirect fully-owned subsidiaries, may obtain, hold or process such information. The Fund cannot guarantee the security of non-public personal information in the possession of such a service provider and cannot guarantee that service providers have been and will continue to comply with the GLBA, other data security and privacy laws and any other related regulatory requirements. Violations of the GLBA and other laws could subject the Fund to litigation and/or fines, penalties or other regulatory action, which, individually or in the aggregate, could have an adverse effect on the Fund. The Fund may also face regulations related to privacy and data security in the other jurisdictions in which the Fund invests.

Private Placements and Restricted Securities Risk [Member]

General Description of Registrant [Abstract]

Risk [Text Block]

Private Placements and Restricted Securities Risk

A private placement involves the sale of securities that have not been registered under the 1933 Act, or relevant provisions of applicable non-U.S. law, to certain institutional and qualified individual purchasers, such as the Fund. In addition to the general risks to which all securities are subject, securities received in a private placement generally are subject to strict restrictions on resale, and there may be no liquid secondary market or ready purchaser for such securities. Therefore, the Fund may be unable to dispose of such securities when it desires to do so, or at the most favorable time or price. Private placements may also raise valuation risks.

Restricted securities are often purchased at a discount from the market price of unrestricted securities of the same issuer reflecting the fact that such securities may not be readily marketable without some time delay. Such securities are often more difficult to value and the sale of such securities often requires more time and results in higher brokerage charges or dealer discounts and other selling expenses than does the sale of securities trading on national securities exchanges or in the over-the-counter markets. Until the Fund can sell such securities into the public markets, its holdings may be less liquid and any sales will need to be made pursuant to an exemption under the Securities Act.

Real Estate Risk [Member]

General Description of Registrant [Abstract]

Risk [Text Block]

Real Estate Risk

To the extent that the Fund invests in real estate investments, including investments in equity or debt securities issued by private and public REITs, real estate operating companies (“REOCs”), private or public real estate-related loans and real estate-linked derivative instruments, it will be subject to the risks associated with owning real estate and with the real estate industry generally. These risks include, but are not limited to: the burdens of ownership of real property; general and local economic conditions (such as an oversupply of space or a reduction in demand for space); the supply and demand for properties (including competition based on rental rates); energy and supply shortages; fluctuations in average occupancy and room rates; the attractiveness, type and location of the properties and changes in the relative popularity of commercial properties as an investment; the financial condition and resources of tenants, buyers and sellers of properties; increased mortgage defaults; the quality of maintenance, insurance and management services; changes in the availability of debt financing which may render the sale or refinancing of properties difficult or impracticable; changes in building, environmental and other laws and/or regulations (including those governing usage and improvements), fiscal policies and zoning laws; changes in real property tax rates; changes in interest rates and the availability of mortgage funds which may render the sale or refinancing of properties difficult or impracticable; changes in operating costs and expenses; energy and supply shortages; uninsured losses or delays from casualties or condemnation; negative developments in the economy that depress travel or leasing activity; environmental liabilities; contingent liabilities on disposition of assets; uninsured or uninsurable casualties; acts of God, including earthquakes, hurricanes and other natural disasters; social unrest and civil disturbances, epidemics, pandemics or other public crises; terrorist attacks and war; risks and operating problems arising out of the presence of certain construction materials, structural or property level latent defects, work stoppages, shortages of labor, strikes, union relations and contracts, fluctuating prices and supply of labor and/or other labor-related factor; and other factors which are beyond the control of PIMCO and its affiliates.

In addition, the Fund’s investments will be subject to various risks which could cause fluctuations in occupancy, rental rates, operating income and expenses or which could render the sale or financing of its properties difficult or unattractive. For example, following the termination or expiration of a tenant’s lease, there may be a period of time before receiving rental payments under a replacement lease. During that period, the Fund would continue to bear fixed expenses such as interest, real estate taxes, maintenance and other operating expenses. In addition, declining economic conditions may impair the ability to attract replacement tenants and achieve rental rates equal to or greater than the rents paid under previous leases. Increased competition for tenants may require capital improvements to properties which would not have otherwise been planned.

Ultimately, to the extent it is not possible to renew leases or re-let space as leases expire, decreased cash flow from tenants will result, which could adversely impact the Fund’s operating results.

Real estate values have historically been cyclical. As the general economy grows, demand for real estate increases and occupancies and rents may increase. As occupancies and rents increase, property values increase, and new development occurs. As development may occur, occupancies, rents and property values may decline. Because leases are usually entered into for long periods and development activities often require extended times to complete, the real estate value cycle often lags the general business cycle. Because of this cycle, real estate companies may incur large swings in their profits and the prices of their securities. Developments following the onset of COVID-19 have adversely impacted certain commercial real estate markets, causing the deferral of mortgage payments, renegotiated commercial mortgage loans, commercial real estate vacancies or outright mortgage defaults, and potential acceleration of macro trends such as work from home and online shopping which may negatively impact certain industries, such as brick-and-mortar retail.

The total returns available from investments in real estate generally depend on the amount of income and capital appreciation generated by the related properties. The performance of real estate, and thereby the Fund, will be reduced by any related expenses, such as expenses paid directly at the property level and other expenses that are capitalized or otherwise embedded into the cost basis of the real estate.

Separately, certain service providers to the Fund and/or its subsidiaries, as applicable, with respect to its real state or real estate-related investments are expected to be, or are owned by, employed by, or otherwise related to, PIMCO, Allianz SE, their affiliates and/or their respective employees, consultants and other personnel. PIMCO may, in its sole discretion, determine to provide, or engage or recommend an

affiliate of PIMCO to provide, certain services to the Fund, instead of engaging or recommending one or more third parties to provide such services. Subject to the governance requirements of a particular fund and applicable law, PIMCO or its affiliates, as applicable, will receive compensation in connection with the provision of such services. As a result, PIMCO faces a conflict of interest when selecting or recommending service providers for the Fund. Fees paid to an affiliated service provider will be determined in PIMCO’s commercially reasonable discretion. Although PIMCO has adopted various policies and procedures intended to mitigate or otherwise manage conflicts of interest with respect to affiliated service providers, there can be no guarantee that such policies and procedures (which may be modified or terminated at any time in PIMCO’s sole discretion) will be successful.

Privately Issued Mortgage-Related Securities Risk

There are no direct or indirect government or agency guarantees of payments in pools created by non-governmental issuers. Privately-issued mortgage-related securities are also not subject to the same

underwriting requirements for the underlying mortgages that are applicable to those mortgage-related securities that have a government or government-sponsored entity guarantee.

Privately-issued mortgage-related securities are not traded on an exchange and there may be a limited market for the securities, especially when there is a perceived weakness in the mortgage and real estate market sectors. Without an active trading market, mortgage-related securities held in the Fund’s portfolio may be particularly difficult to value because of the complexities involved in assessing the value of the underlying mortgage loans.

Regulation S Securities Risk [Member]

General Description of Registrant [Abstract]

Risk [Text Block]

Regulation S Securities Risk

Regulation S securities are offered through off-shore (non-U.S.) offerings without registration with the SEC pursuant to Regulation S of the Securities Act. Because Regulation S securities are subject to legal or contractual restrictions on resale, Regulation S securities may be considered illiquid. Furthermore, because Regulation S securities are generally less liquid than registered securities, a Fund may take longer to liquidate these positions than would be the case for publicly traded securities. Although Regulation S securities may be resold in privately negotiated transactions, the price realized from these sales could be less than off-shore transactions or in those originally paid by the Fund. Further, companies whose securities are not publicly traded may not be subject to the disclosure and other investor protection requirements that would be applicable if their securities were publicly traded. Accordingly, Regulation S securities may involve a high degree of business and financial risk and may result in substantial losses.

Regulatory Changes Risk [Member]

Risk [Text Block]

Regulatory Changes Risk

Financial entities, such as investment companies and investment advisers, are generally subject to extensive government regulation and intervention. Government regulation and/or intervention may change the way the Fund is regulated, affect the expenses incurred directly by the Fund and the value of its investments, and limit and /or preclude the Fund’s ability to achieve its investment objective. Government regulation may change frequently and may have significant adverse consequences. The Fund and the Investment Manager have historically been eligible for exemptions from certain regulations. However, there is no assurance that the Fund and the Investment Manager will continue to be eligible for such exemptions. Actions by governmental entities may also impact certain instruments in which the Fund invests.

Moreover, government regulation may have unpredictable and unintended effects. Legislative or regulatory actions to address

perceived liquidity or other issues in fixed income markets generally, or in particular markets such as the municipal securities market, may alter or impair the Fund’s ability to pursue its investment objectives or utilize certain investment strategies and techniques.

Regulatory Risk — Commodity Pool Operator

The CFTC has adopted regulations that subject registered investment companies and their investment advisers to regulation by the CFTC if the registered investment company invests more than a prescribed level of its liquidation value in futures, options on futures or commodities, swaps, or other financial instruments regulated under the CEA and the rules thereunder (“commodity interests”), or if the Fund markets itself as providing investment exposure to such instruments. The Investment Manager is registered with the CFTC as a CPO. However, with respect to the Fund, the Investment Manager has claimed an exclusion from registration as a CPO pursuant to CFTC Rule 4.5. For the Investment Manager to remain eligible for this exclusion, the Fund must comply with certain limitations, including limits on its ability to use any commodity interests and limits on the manner in which the Fund holds out its use of such commodity interests. These limitations may restrict the Fund’s ability to pursue its investment objectives and strategies, increase the costs of implementing its strategies, result in higher expenses for the Fund, and/or adversely affect the Fund’s total return. To the extent the Fund becomes ineligible for this exclusion from CFTC regulation, the Fund may consider steps in order to continue to qualify for exemption from CFTC regulation, or may determine to operate subject to CFTC regulation.

Regulatory Risk LIBOR [Member]

General Description of Registrant [Abstract]

Risk [Text Block]

Regulatory Risk — LIBOR

Certain instruments in which the Fund may invest have relied or continue in some fashion upon the London Interbank Offered Rate (“LIBOR”). LIBOR was traditionally an average interest rate, determined by the ICE Benchmark Administration, that banks charge one another for the use of short-term money. On March 5, 2021, the Financial Conduct Authority (“FCA”), the United Kingdom’s financial regulatory body and regulator of LIBOR, publicly announced that all U.S. Dollar LIBOR settings will either cease to be provided by any administrator or will no longer be representative (i) immediately after December 31, 2021 for one-week and two-month U.S. Dollar LIBOR settings and (ii) immediately after June 30, 2023 for the remaining U.S. Dollar LIBOR settings. As of January 1, 2022, as a result of supervisory guidance from U.S. regulators, U.S. regulated entities have generally ceased entering into new LIBOR contracts with limited exceptions. Publication of all Japanese yen and the one- and six-month sterling LIBOR settings have ceased, and while publication of the three-month Sterling LIBOR setting will continue through at least the end of March 2024 on the basis of a changed methodology (known as “synthetic LIBOR”), this rate has been designated by the FCA as unrepresentative of the underlying market that it seeks to

measure and is solely available for use in legacy transactions. Certain bank-sponsored committees in other jurisdictions, including Europe, the United Kingdom, Japan and Switzerland, have selected alternative reference rates denominated in other currencies. Although the transition process away from LIBOR for many instruments has been completed, some LIBOR use is continuing and there are potential effects related to the transition away from LIBOR or continued use of LIBOR on the Fund, or on certain instruments in which the Fund invests, which can be difficult to ascertain, and may vary depending on factors that include, but are not limited to: (i) existing fallback or termination provisions in individual contracts and (ii) whether, how, and when industry participants adopt new reference rates for affected instruments. So-called “tough legacy” contracts have LIBOR interest rate provisions with no fallback provisions contemplating a permanent discontinuation of LIBOR, inadequate fallback provisions or fallback provisions which may not effectively result in a transition away from LIBOR prior to LIBOR’s planned replacement date. On March 15, 2022, the Adjustable Interest Rate (LIBOR) Act was signed into law. This law provides a statutory fallback mechanism on a nationwide basis to replace LIBOR with a benchmark rate that is selected by the Board of Governors of the Federal Reserve System based on the Secured Overnight Financing Rate (“SOFR”) for tough legacy contracts. On February 27, 2023, the Federal Reserve System’s final rule in connection with this law became effective, establishing benchmark replacements based on SOFR and Term SOFR (a forward-looking measurement of market expectations of SOFR implied from certain derivatives markets) for applicable tough legacy contracts governed by U.S. law. In addition, the FCA has announced that it will require the publication of synthetic LIBOR for the one-month, three-month and six-month U.S. Dollar LIBOR settings after June 30, 2023 through at least September 30, 2024. Certain of the Fund’s investments may involve individual tough legacy contracts which may be subject to the Adjustable Interest Rate (LIBOR) Act or synthetic LIBOR and no assurances can be given that these measures will have had the intended effects. Moreover, certain aspects of the transition from LIBOR have relied or will continue to rely on the actions of third-party market participants, such as clearing houses, trustees, administrative agents, asset servicers and certain service providers; PIMCO cannot guarantee the performance of such market participants and any failure on the part of such market participants to manage their part of the LIBOR transition could impact the Fund. The transition of investments from LIBOR to a replacement rate as a result of amendment, application of existing fallbacks, statutory requirements or otherwise may also result in a reduction in the value of certain instruments held by the Fund or a reduction in the effectiveness of related Fund transactions such as hedges. In addition, an instrument’s transition to a replacement rate could result in variations in the reported yields of the Fund that holds such instrument. Any such

effects of the transition away from LIBOR, as well as other unforeseen effects, could result in losses to the Fund.

Reinvestment Risk [Member]

General Description of Registrant [Abstract]

Risk [Text Block]

Reinvestment Risk

Income from the Fund’s portfolio will decline if and when the Fund invests the proceeds from matured, traded or called debt obligations at market interest rates that are below the portfolio’s current earnings rate. For instance, during periods of declining interest rates, an issuer of debt obligations may exercise an option to redeem securities prior to maturity, forcing the Fund to invest in lower-yielding securities. The Fund also may choose to sell higher yielding portfolio securities and to purchase lower yielding securities to achieve greater portfolio diversification, because the portfolio managers believe the current holdings are overvalued or for other investment-related reasons. A decline in income received by the Fund from its investments is likely to have a negative effect on dividend levels and the market price, NAV and/or overall return of the Common Shares.

REIT Risk [Member]

General Description of Registrant [Abstract]

Risk [Text Block]

REIT Risk

REITs are pooled investment vehicles that own, and usually operate, income-producing real estate. Some REITs also finance real estate. If a REIT meets certain requirements, including distributing to shareholders substantially all of its taxable income (other than net capital gains), then it is not typically taxed on the income distributed to shareholders. Therefore, REITs may pay higher dividends than other issuers.

REITs can be divided into three basic types: Equity REITs, Mortgage REITs and Hybrid REITs. Equity REITs invest the majority of their assets directly in real property. They derive their income primarily from rents received and any profits on the sale of their properties. Mortgage REITs invest the majority of their assets in real estate mortgages and derive most of their income from mortgage interest payments. As its name suggests, Hybrid REITs combine characteristics of both Equity REITs and Mortgage REITs.

An investment in a REIT, or in a real estate linked derivative instrument linked to the value of a REIT, is subject to the risks that impact the value of the underlying properties of the REIT. These risks include loss to casualty or condemnation, and changes in supply and demand, interest rates, zoning laws, regulatory limitations on rents, property taxes and operating expenses. Other factors that may adversely affect REITs include poor performance by management of the REIT, changes to the tax laws, or failure by the REIT to qualify for favorable tax treatment. The securities of REITs involve greater risks than those associated with larger, more established companies and may be subject to more abrupt or erratic price movements because of interest rate changes, economic conditions and other factors. For example, the value of these securities may decline when interest rates rise and will also be affected by the real estate market and by the

management or development of the underlying properties. The underlying properties may be subject to mortgage loans, which may also be subject to the risks of default. REITs are also subject to default by borrowers and self-liquidation, and are heavily dependent on cash flow. Some REITs lack diversification because they invest in a limited number of properties, a narrow geographic area, or a single type of property. Mortgage REITs may be impacted by the quality of the credit extended.

Repurchase Agreements Risk [Member]

General Description of Registrant [Abstract]

Risk [Text Block]

Repurchase Agreements Risk

The Fund may enter into repurchase agreements, in which the Fund purchases a security from a bank or broker-dealer, which agrees to repurchase the security at the Fund’s cost plus interest within a specified time. If the party agreeing to repurchase should default, the Fund would seek to sell the securities which it holds. This could involve procedural costs or delays in addition to a loss on the securities if their value should fall below their repurchase price. Repurchase agreements may be or become illiquid. These events could also trigger adverse tax consequences for the Fund.

Risk Retention Investment Risk [Member]

General Description of Registrant [Abstract]

Risk [Text Block]

Risk Retention Investment Risk

The Fund may invest in risk retention tranches of commercial mortgage-backed securities (“CMBS”) or other eligible securitizations, if any (“risk retention tranches”), which are eligible residual interests held by the sponsors of such securitizations pursuant to the final rules implementing the credit risk retention requirements of Section 941 of the Dodd-Frank Act (the “U.S. Risk Retention Rules”). In the case of CMBS transactions, for example, the U.S. Risk Retention Rules permit all or a portion of the retained credit risk associated with certain securitizations (i.e., retained risk) to be held by an unaffiliated “third party purchaser,” such as the Fund, if, among other requirements, the third-party purchaser holds its retained interest, unhedged, for at least five years following the closing of the CMBS transaction, after which it is entitled to transfer its interest in the securitization to another person that meets the requirements for a third-party purchaser. Even after the required holding period has expired, due to the generally illiquid nature of such investments, no assurance can be given as to what, if any, exit strategies will ultimately be available for any given position.

In addition, there is limited guidance on the application of the final U.S. Risk Retention Rules to specific securitization structures. There can be no assurance that the applicable federal agencies charged with the implementation of the final U.S. Risk Retention Rules (the Federal Deposit Insurance Corporation, the Comptroller of the Currency, the Federal Reserve Board, the SEC, the Department of Housing and Urban Development, and the Federal Housing Finance Agency) could not take positions in the future that differ from the interpretation of such rules taken or embodied in such securitizations, or that the final U.S. Risk Retention Rules will not change.

Furthermore, in situations where the Fund invests in risk retention tranches of securitizations structured by third parties, the Fund may be required to execute one or more letters or other agreements, the exact form and nature of which will vary (each, a “Risk Retention Agreement”) under which it will make certain undertakings designed to ensure such securitization complies with the U.S. Risk Retention Rules. Such Risk Retention Agreements may include a variety of representations, warranties, covenants and other indemnities, each of which may run to various transaction parties. If the Fund breaches any undertakings in any Risk Retention Agreement, it will be exposed to claims by the other parties thereto, including for any losses incurred as a result of such breach, which could be significant and exceed the value of the Fund’s investments.

Securities Lending Risk [Member]

General Description of Registrant [Abstract]

Risk [Text Block]

Securities Lending Risk

For the purpose of achieving income, the Fund may lend its portfolio securities to brokers, dealers, and other financial institutions provided a number of conditions are satisfied, including that the loan is fully collateralized. When the Fund lends portfolio securities, its investment performance will continue to reflect changes in the value of the securities loaned, and the Fund will also receive a fee or interest on the collateral. Securities lending involves the risk of loss of rights in the collateral or delay in recovery of the collateral if the borrower fails to return the security loaned or becomes insolvent. The Fund may pay lending fees to a party arranging the loan. Cash collateral received by the Fund in securities lending transactions may be invested in short-term liquid fixed income instruments or in money market or short-term mutual funds, or similar investment vehicles, including affiliated money market or short-term mutual funds. The Fund bears the risk of such investments.

Senior Debt Risk [Member]

General Description of Registrant [Abstract]

Risk [Text Block]

Senior Debt Risk

The Fund may be subject to greater levels of credit risk than funds that do not invest in below investment grade senior debt. The Fund may also be subject to greater levels of liquidity risk than funds that do not invest in senior debt. Restrictions on transfers in loan agreements, a lack of publicly available information and other factors may, in certain instances, make senior debt more difficult to sell at an advantageous time or price than other types of securities or instruments. Additionally, if the issuer of senior debt prepays, the Fund will have to consider reinvesting the proceeds in other senior debt or similar instruments that may pay lower interest rates.

Short Exposure Risk [Member]

General Description of Registrant [Abstract]

Risk [Text Block]

Short Exposure Risk

The Fund’s short sales and short positions, if any, are subject to special risks. A short sale involves the sale by the Fund of a security that it does not own with the hope of purchasing the same security at a later date at a lower price. The Fund may also enter into a short position through a forward commitment or a short derivative position

through a futures contract or swap agreement. If the price of the security or derivative has increased during this time, then the Fund will incur a loss equal to the increase in price from the time that the short sale was entered into plus any transaction costs (i.e., premiums and interest) paid to the broker-dealer to borrow securities. Therefore, short sales involve the risk that losses may be exaggerated, potentially losing more money than the actual cost of the investment. By contrast, a loss on a long position arises from decreases in the value of the security and is limited by the fact that a security’s value cannot decrease below zero.

By investing the proceeds received from selling securities short, the Fund could be deemed to be employing a form of leverage, which creates special risks. The use of leverage may increase the Fund’s exposure to long security positions and make any change in the Fund’s NAV greater than it would be without the use of leverage. This could result in increased volatility of returns. There is no guarantee that any leveraging strategy the Fund employs will be successful during any period in which it is employed.

In times of unusual or adverse market, economic, regulatory or political conditions, the Fund may not be able, fully or partially, to implement its short selling strategy. Periods of unusual or adverse market, economic, regulatory or political conditions generally may exist for long periods of time. Also, there is the risk that the third party to the short sale or short position will not fulfill its contractual obligations, causing a loss to the Fund.

Special Purpose Acquisition Companies (SPACs) Risk [Member]

General Description of Registrant [Abstract]

Risk [Text Block]

Special Purpose Acquisition Companies (“SPACs”) Risk

The Fund may invest in securities of SPACs or similar special purpose entities that pool funds to seek potential acquisition opportunities. Unless and until an acquisition is completed, a SPAC generally invests its assets (less a portion retained to cover expenses) in US government securities, money market securities or holds cash; if an acquisition that meets the requirements for the SPAC is not completed within a pre-established period of time, the invested funds are returned to the entity’s shareholders unless shareholders approve alternative options. Because SPACs and similar entities are in essence blank check companies without operating history or ongoing business other than seeking acquisitions, the value of their securities is particularly dependent on the ability of the entity’s management to identify and complete a profitable acquisition. A SPAC’s structure may result in significant dilution of a stockholder’s share value immediately upon the completion of a business combination due to, among other reasons, interests held by the SPAC sponsor, conversion of warrants into additional shares, shares issued in connection with a business combination and/or certain embedded costs. There is no guarantee that the SPACs in which the Fund invests will complete an acquisition or that any acquisitions that are completed will be profitable. Some

SPACs may pursue acquisitions only within certain industries or regions, which may increase the volatility of their prices. In addition, these securities, which are typically traded in the over-the-counter market, may be considered illiquid and/or be subject to restrictions on resale.

Smaller Company Risk [Member]

General Description of Registrant [Abstract]

Risk [Text Block]

Smaller Company Risk

The general risks associated with debt instruments or equity securities are particularly pronounced for securities issued by companies with small market capitalizations. Small capitalization companies involve certain special risks. They are more likely than larger companies to have limited product lines, markets or financial resources, or to depend on a small, inexperienced management group. Securities of smaller companies may trade less frequently and in lesser volume than more widely held securities and their values may fluctuate more sharply than other securities. They may also have limited liquidity. These securities may therefore be more vulnerable to adverse developments than securities of larger companies, and the Fund may have difficulty purchasing or selling securities positions in smaller companies at prevailing market prices. Also, there may be less publicly available information about smaller companies or less market interest in their securities as compared to larger companies. Companies with medium-sized market capitalizations may have risks similar to those of smaller companies.

Sovereign Debt Risk [Member]

General Description of Registrant [Abstract]

Risk [Text Block]

Sovereign Debt Risk

In addition to the other risks applicable to debt investments, sovereign debt may decline in value as a result of default or other adverse credit event resulting from an issuer’s inability or unwillingness to make principal or interest payments in a timely fashion. A sovereign entity’s failure to make timely payments on its debt can result from many factors, including, without limitation, insufficient foreign (non-U.S.) currency reserves or an inability to sufficiently manage fluctuations in relative currency valuations, an inability or unwillingness to satisfy the demands of creditors and/or relevant supranational entities regarding debt service or economic reforms, the size of the debt burden relative to economic output and tax revenues, cash flow difficulties, and other political and social considerations. The risk of loss to the Fund in the event of a sovereign debt default or other adverse credit event is heightened by the unlikelihood of any formal recourse or means to enforce its rights as a holder of the sovereign debt. In addition, sovereign debt restructurings, which may be shaped by entities and factors beyond the Fund’s control, may result in a loss in value of the Fund’s sovereign debt holdings.

Structured Investments Risk [Member]

General Description of Registrant [Abstract]

Risk [Text Block]

Structured Investments Risk

Holders of structured products, including structured notes, credit-linked notes and other types of structured products, bear the risks of the underlying investments, index or reference obligation and are

subject to counterparty risk. The Fund may have the right to receive payments only from the structured product, and generally does not have direct rights against the issuer or the entity that sold the assets to be securitized. While certain structured products enable the investor to acquire interests in a pool of securities without the brokerage and other expenses associated with directly holding the same securities, investors in structured products generally pay their share of the structured product’s administrative and other expenses. Although it is difficult to predict whether the prices of indices and securities underlying structured products will rise or fall, these prices (and, therefore, the prices of structured products) are generally influenced by the same types of political and economic events that affect issuers of securities and capital markets generally. If the issuer of a structured product uses shorter term financing to purchase longer term securities, the issuer may be forced to sell its securities at below market prices if it experiences difficulty in obtaining such financing, which may adversely affect the value of the structured products owned by the Fund. Structured products generally entail risks associated with derivative instruments.

Subprime Risk [Member]

General Description of Registrant [Abstract]

Risk [Text Block]

Subprime Risk

Loans, and debt instruments collateralized by loans (including Alt Lending ABS), acquired by the Fund may be subprime in quality, or may become subprime in quality. Although there is no specific legal or market definition of “subprime,” subprime loans are generally understood to refer to loans made to borrowers that display poor credit histories and other characteristics that correlate with a higher default risk. Accordingly, subprime loans, and debt instruments secured by such loans (including Alt Lending ABS), have speculative characteristics and are subject to heightened risks, including the risk of nonpayment of interest or repayment of principal, and the risks associated with investments in high yield securities. In addition, these instruments could be subject to increased regulatory scrutiny. The Fund is not restricted by any particular borrower credit risk criteria and/or qualifications when acquiring loans or debt instruments collateralized by loans.

Subsidiary Risk [Member]

General Description of Registrant [Abstract]

Risk [Text Block]

Subsidiary Risk

To the extent the Fund invests through one or more of its subsidiaries, the Fund would be exposed to the risks associated with such subsidiary’s investments. Such subsidiaries would likely not be registered as investment companies under the 1940 Act and therefore would not be subject to all of the investor protections of the 1940 Act. Changes in the laws of the United States and/or the jurisdiction in which a subsidiary is organized could result in the inability of the Fund and/or the subsidiary to operate as intended and could adversely affect the Fund.

Synthetic Convertible Securities Risk [Member]

General Description of Registrant [Abstract]

Risk [Text Block]

Synthetic Convertible Securities Risk

Synthetic convertible securities involve the combination of separate securities that possess the two principal characteristics of a traditional convertible security (i.e., an income-producing component and a right to acquire an equity security). Synthetic convertible securities are often achieved, in part, through investments in warrants or options to buy common stock (or options on a stock index), and therefore are subject to the risks associated with derivatives. The value of a synthetic convertible security will respond differently to market fluctuations than a traditional convertible security because a synthetic convertible is composed of two or more separate securities or instruments, each with its own market value. Because the convertible component is typically achieved by investing in warrants or options to buy common stock at a certain exercise price, or options on a stock index, synthetic convertible securities are subject to the risks associated with derivatives. In addition, if the value of the underlying common stock or the level of the index involved in the convertible component falls below the exercise price of the warrant or option, the warrant or option may lose all value.

Tax Risk [Member]

General Description of Registrant [Abstract]

Risk [Text Block]

Tax Risk

The Fund has elected to be treated as a “regulated investment company” (a “RIC”) under the Code and intends each year to qualify and be eligible to be treated as such, so that it generally will not be subject to U.S. federal income tax on its net investment income or net short-term or long-term capital gains, that are distributed (or deemed distributed, as described below) to shareholders. In order to qualify and be eligible for such treatment, the Fund must meet certain asset diversification tests, derive at least 90% of its gross income for such year from certain types of qualifying income, and distribute to its shareholders at least 90% of its “investment company taxable income” as that term is defined in the Code (which includes, among other things, dividends, taxable interest and the excess of any net short-term capital gains over net long-term capital losses, as reduced by certain deductible expenses).

The Fund’s investment strategy will potentially be limited by its intention to continue qualifying for treatment as a RIC, and can limit the Fund’s ability to continue qualifying as such. The tax treatment of certain of the Fund’s investments under one or more of the qualification or distribution tests applicable to regulated investment companies is uncertain. An adverse determination or future guidance by the IRS or a change in law might affect the Fund’s ability to qualify or be eligible for treatment as a RIC. Income and gains from certain of a Fund’s activities may not constitute qualifying income to a RIC for purposes of the 90% gross income test. If a Fund were to treat income or gain from a particular investment or activity as qualifying income and the income or gain were later determined not to constitute qualifying income and, together with any other nonqualifying income,

caused the Fund’s nonqualifying income to exceed 10% of its gross income in any taxable year, the Fund would fail to qualify as a RIC unless it is eligible to and does pay a tax at the Fund level.

If, in any year, the Fund were to fail to qualify for treatment as a RIC under the Code and were ineligible to or did not otherwise cure such failure, the Fund would be subject to tax on its taxable income at corporate rates and, when such income is distributed, shareholders would be subject to further tax on such distributions to the extent of the Fund’s current or accumulated earnings and profits.

U.S. Government Securities Risk [Member]

General Description of Registrant [Abstract]

Risk [Text Block]

U.S. Government Securities Risk

Certain U.S. Government Securities such as U.S. Treasury bills, notes and bonds and mortgage-related securities guaranteed by the GNMA, are supported by the full faith and credit of the United States; others, such as those of Federal Home Loan Banks (“FHLBs”) or the Federal Home Loan Mortgage Corporation (“FHLMC”), are supported by the right of the issuer to borrow from the U.S. Treasury; others, such as those of the FNMA, are supported by the discretionary authority of the U.S. Government to purchase the agency’s obligations; and still others are supported only by the credit of the agency, instrumentality or corporation. U.S. government securities are subject to market risk, interest rate risk and credit risk. Although legislation has been enacted to support certain government sponsored entities, including the FHLBs, FHLMC and FNMA, there is no assurance that the obligations of such entities will be satisfied in full, or that such obligations will not decrease in value or default. It is difficult, if not impossible, to predict the future political, regulatory or economic changes that could impact the government sponsored entities and the values of their related securities or obligations. In addition, certain governmental entities, including FNMA and FHLMC, have been subject to regulatory scrutiny regarding their accounting policies and practices and other concerns that may result in legislation, changes in regulatory oversight and/or other consequences that could adversely affect the credit quality, availability or investment character of securities issued by these entities. Yields available from U.S. Government debt securities are generally lower than the yields available from such other securities. The values of U.S. Government Securities change as interest rates fluctuate.

Periodically, uncertainty regarding the status of negotiations in the U.S. government to increase the statutory debt ceiling could increase the risk that the U.S. government may default on payments on certain U.S. government securities, cause the credit rating of the U.S. government to be downgraded, increase volatility in the stock and bond markets, result in higher interest rates, reduce prices of U.S. Treasury and other securities, and/or increase the costs of various kinds of debt. If a government-sponsored entity is negatively impacted by legislative or regulatory action (or lack thereof), is unable to meet

its obligations, or its creditworthiness declines, the performance of a fund that holds securities of the entity will be adversely impacted.

Valuation Risk [Member]

General Description of Registrant [Abstract]

Risk [Text Block]

Valuation Risk

Certain securities in which the Fund invests may be less liquid and more difficult to value than other types of securities. Investments for which market quotations are not readily available are valued at fair value as determined in good faith pursuant to Rule 2a-5 under the 1940 Act. Fair value pricing may require subjective determinations about the value of a security or other asset. As a result, there can be no assurance that fair value pricing will result in adjustments to the prices of securities or other assets or that fair value pricing will reflect actual market value, and it is possible that the fair value determined for a security or other asset will be materially different from quoted or published prices, from the prices used by others for the same security or other asset and/or from the value that actually could be or is realized upon the sale of that security or other asset.

ZeroCoupon Bond, StepUps and PaymentInKind Securities Risk [Member]

General Description of Registrant [Abstract]

Risk [Text Block]

Zero-Coupon Bond, Step-Ups and Payment-In-Kind Securities Risk

The market prices of zero-coupon, step-ups and payment-in-kind securities are generally more volatile than the prices of securities that pay interest periodically and in cash and are likely to respond to changes in interest rates to a greater degree than other types of debt securities with similar maturities and credit quality. Because zero-coupon securities bear no interest, their prices are especially volatile. And because zero-coupon bondholders do not receive interest payments, the prices of zero-coupon securities generally fall more dramatically than those of bonds that pay interest on a current basis when interest rates rise. The market for zero-coupon and payment-in-kind securities may suffer decreased liquidity. In addition, as these securities may not pay cash interest, the Fund’s investment exposure to these securities and their risks, including credit risk, will increase during the time these securities are held in the Fund’s portfolio. Further, to maintain its qualification for treatment as a RIC and to avoid Fund-level U.S. federal income and/or excise taxes, the Fund is required to distribute to its shareholders any income it is deemed to have received in respect of such investments, notwithstanding that cash has not been received currently, and the value of paid-in-kind interest. Consequently, the Fund may have to dispose of portfolio securities under disadvantageous circumstances to generate the cash or may have to leverage itself by borrowing the cash to satisfy this distribution requirement. The required distributions, if any, would result in an increase in the Fund’s exposure to these securities. Zero coupon bonds, step-ups and payment-in-kind securities allow an issuer to avoid or delay the need to generate cash to meet current interest payments and, as a result, may involve greater credit risk than bonds that pay interest currently or in cash. The Fund would be required to distribute the income on these instruments as it

accrues, even though the Fund will not receive the income on a current basis or in cash. Thus, the Fund may sell other investments, including when it may not be advisable to do so, to make income distributions to its shareholders.

Interest Rate Risk [Member]

General Description of Registrant [Abstract]

Risk [Text Block]

Interest Rate Risk

Interest rate risk is the risk that fixed income securities and other instruments in the Fund’s portfolio will fluctuate in value because of a change in interest rates. For example, as nominal interest rates rise, the value of certain fixed income securities held by the Fund is likely to decrease. A nominal interest rate can be described as the sum of a real interest rate and an expected inflation rate. Interest rate changes can be sudden and unpredictable, and the Fund may lose money as a result of movements in interest rates. The Fund may not be able to effectively hedge against changes in interest rates or may choose not to do so for cost or other reasons.

A wide variety of factors can cause interest rates or yields of U.S. Treasury securities (or yields of other types of bonds) to rise, including but not limited to central bank monetary policies, changing inflation or real growth rates, general economic conditions, increasing bond issuances or reduced market demand for low yielding investments. Risks associated with rising interest rates are heightened under current market conditions given that the U.S. Federal Reserve (the “Federal Reserve”) has raised interest rates from historically low levels. In addition, changes in monetary policy may exacerbate the risks associated with changing interest rates. Further, in market environments where interest rates are rising, issuers may be less willing or able to make principal and interest payments on fixed-income investments when due.

Further, fixed income securities with longer durations tend to be more sensitive to changes in interest rates, usually making them more volatile. Duration is a measure used to determine the sensitivity of a security’s price to changes in interest rates that incorporates a security’s yield, coupon, final maturity and call features, among other characteristics. Duration is useful primarily as a measure of the sensitivity of a fixed income security’s market price to interest rate (i.e., yield) movements. All other things remaining equal, for each one

percentage point increase in interest rates, the value of a portfolio of fixed income investments would generally be expected to decline by one percent for every year of the portfolio’s average duration above zero. For example, the value of a portfolio of fixed income securities with an average duration of eight years would generally be expected to decline by approximately 8% if interest rates rose by one percentage point.

Variable and floating rate securities may decline in value if their interest rates do not rise as much, or as quickly, as interest rates in general. Conversely, floating rate securities will not generally increase in value if interest rates decline. Inverse floating rate securities may decrease in value if interest rates increase. Inverse floating rate securities may also exhibit greater price volatility than a fixed rate obligation with similar credit quality. When the Fund holds variable or floating rate securities, a decrease (or, in the case of inverse floating rate securities, an increase) in market interest rates will adversely affect the income received from such securities and the NAV of the Fund’s shares.

During periods of very low or negative interest rates, the Fund may be unable to maintain positive returns. Very low or negative interest rates may magnify interest rate risk. Changing interest rates, including rates that fall below zero, may have unpredictable effects on markets, may result in heightened market volatility and may detract from Fund performance to the extent the Fund is exposed to such interest rates.

Measures such as average duration may not accurately reflect the true interest rate sensitivity of the Fund. This is especially the case if the Fund consists of securities with widely varying durations. Therefore, if the Fund has an average duration that suggests a certain level of interest rate risk, the Fund may in fact be subject to greater interest rate risk than the average would suggest. This risk is greater to the extent the Fund uses leverage or derivatives in connection with the management of the Fund.

Convexity is an additional measure used to understand a security’s or Fund’s interest rate sensitivity. Convexity measures the rate of change of duration in response to changes in interest rates. With respect to a security’s price, a larger convexity (positive or negative) may imply more dramatic price changes in response to changing interest rates. Convexity may be positive or negative. Negative convexity implies that interest rate increases result in increased duration, meaning increased sensitivity in prices in response to rising interest rates. Thus, securities with negative convexity, which may include bonds with traditional call features and certain mortgage-backed securities, may experience greater losses in periods of rising interest rates. Accordingly, if the Fund holds such securities, the Fund may be subject to a greater risk of losses in periods of rising interest rates.

Rising interest rates may result in a decline in value of the Fund’s fixed income investments and in periods of volatility. Also, when interest rates rise, issuers are less likely to refinance existing debt securities, causing the average life of such securities to extend. Further, while U.S. bond markets have steadily grown over the past three decades, dealer “market making” ability has remained relatively stagnant. As a result, dealer inventories of certain types of bonds and similar instruments, which provide a core indication of the ability of financial intermediaries to “make markets,” are at or near historic lows in relation to market size. Because market makers provide stability to a market through their intermediary services, a significant reduction in dealer inventories could potentially lead to decreased liquidity and increased volatility in the fixed income markets. Such issues may be exacerbated during periods of economic uncertainty. All of these factors, collectively and/or individually, could cause the Fund to lose value.

[1] In the event that the Common Shares to which this relates are sold to or through underwriters or dealer managers, a corresponding supplement will disclose the applicable sale load and/or commission.

[2] You will pay broker chargers if you direct your broker or the plan agent to sell your Common Shares that you acquired pursuant to a dividend reinvestment plan. You may also pay a pro rata share of brokerage commissions incurred in connection with open market purchase pursuant to the Fund’s Dividend Reinvestment Plan.

[3] The related supplement will disclose the estimated amount of offering expense, the offering price and the offering expenses borne by the Fund and indirectly by all of its Common Shareholders as a percentage of the offering price.

[4] Management fees include fees payable to the Investment Manager for advisory services and for supervisory, administrative and other services. The Fund pays for the advisory, supervisory and administrative services it requires under what is essentially an all-in fee structure. Pursuant to an investment management agreement, PIMCO is paid a Management Fee of 0.76% of the Fund’s average daily net assets (including daily net assets attributable to any preferred shares of the Fund that may be outstanding). The Fund (and not PIMCO) will be responsible for certain fees and expenses which are, reflected in the table above, that are not covered by the management fee under the investment management agreement. Please see Note 9, Fees and Expenses in the Notes to Financial Statements for an explanation of the management fee.

[5] Reflects the Fund’s use of leverage in the form of reverse repurchase agreements averaged over the fiscal year ended June 30, 2023, which represented 18.64% of the Fund’s total average managed assets (including assets attributable to reverse repurchase agreements), at an annual interest rate cost to the Fund of 3.44%, which is the weighted average interest rate cost during the fiscal year ended June 30, 2023. The actual amount of interest expense borne by the Fund will vary over time in accordance with the level of the Fund’s use of reverse repurchase agreements, dollar rolls and/or borrowings and variations in market interest rates. Borrowing expense is required to be treated as an expense of the Fund for accounting purposes. Any associated income or gains (or losses) realized from leverage obtained through such instruments is not reflected in the Annual Fund Operating Expenses table above, but would be reflected in the Fund’s performance results.

[6] Reflects the Fund’s outstanding Preferred Shares averaged over the fiscal year ended June 30, 2023, which represented 6.60% of the Fund’s total average managed assets (including the liquidation preference of outstanding Preferred Shares and assets attributable to reverse repurchase agreements), at an estimated annual dividend rate to the Fund of 8.11% (based on the weighted average Preferred Share dividend rate during the fiscal year ended June 30, 2023) and assumes the Fund will continue to pay Preferred Share dividends at the “maximum applicable rate” called for under the Fund’s Bylaws due to the ongoing failure of auctions for the ARPS. The actual dividend rate paid on the ARPS will vary over time in accordance with variations in market interest rates.

[7] Other expenses are estimated for the Fund’s fiscal year ending June 30, 2024.

[8] “Dividend Cost on Preferred Shares”, including distributions on Preferred Shares, and “Interest Payments on Borrowed Funds” are borne by the Fund separately from management fees paid to PIMCO. Excluding these expenses, Total Annual Fund Operating Expenses are 0.92%. Excluding only distributions on Preferred Shares of 0.71%, Total Annual Fund Operating Expenses are 2.70%.

[9] The example above should not be considered a representation of future expenses. Actual expenses may be higher or lower than those shown. The example assumes that the estimated Interest Payments on Borrowed Funds, Dividend Cost on Preferred Shares and Other Expenses set forth in the Annual Fund Operating Expenses table are accurate, that the rate listed under Total Annual Fund Operating Expenses remains the same each year and that all dividends and distributions are reinvested at NAV. Actual expenses may be greater or less than those assumed. Moreover, the Fund’s actual rate of return may be greater or less than the hypothetical 5% annual return shown in the example. The example does not include commissions or estimated offering expenses, which would cause the expenses shown in the example to increase.

[10] Unaudited. Information is presented in conformance with annual reporting requirements for funds that have filed a registration statement pursuant to General Instruction A.2 of Form N-2 (“Short Form N-2”).

[11] Fiscal year end changed from July 31st to June 30th.

[12] “Asset Coverage per Preferred Share” means the ratio that the value of the total assets of the Fund, less all liabilities and indebtedness not represented by ARPS, bears to the aggregate of the involuntary liquidation preference of ARPS, expressed as a dollar amount per ARPS.

[13] “Involuntary Liquidating Preference“ means the amount to which a holder of ARPS would be entitled upon the involuntary liquidation of the Fund in preference to the Common Shareholders, expressed as a dollar amount per Preferred Share.

[14] Such prices reflect inter-dealer prices, without retail mark-up, mark-down or commission and may not represent actual transactions.

[15] Effective April 1, 2022, the end of the Fund’s Fiscal year changed from July 31 to June 30.

[16] Performance quoted represents past performance. Past performance is not a guarantee or a reliable indicator of future results. Current performance may be lower or higher than performance shown. Investment return and the principal value of an investment will fluctuate. Returns shown do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the sale of Fund shares. Total return, market price, NAV, market price distribution rate, and NAV distribution rate will fluctuate with changes in market conditions. The NAV presented may differ from the NAV reported for the same period in other Fund materials. Performance current to the most recent month-end is available at www.pimco.com or via (844) 33-PIMCO. Performance is calculated assuming all dividends and distributions are reinvested at prices obtained under the Fund’s dividend reinvestment plan. Performance does not reflect any brokerage commissions in connection with the purchase or sale of Fund shares. Performance of an index is shown in light of a requirement by the Securities and Exchange Commission that the performance of an appropriate broad-based securities market index be disclosed. However, the Fund is not managed to an index nor should the index be viewed as a “benchmark” for the Fund’s performance. The index is not intended to be indicative of the Fund’s investment strategies, portfolio components or past or future performance. Please see Additional Information Regarding the Funds for a description of the Fund’s principal investment strategies.
