Expense Example [Table Text Block]

The following table demonstrates the projected dollar amount of cumulative expenses we would pay out of net assets and that you would indirectly bear over various periods with respect to a hypothetical investment in our common stock. In calculating the following expense amounts, we have assumed we have issued $1.75 billion in 5.50% Preferred Stock paying dividends of 5.50% per annum, in addition to our $0.15 billion of 5.35% Preferred Stock paying dividends of 5.35% per annum, we have borrowed $1.6 billion available under our line of credit, in addition to our other indebtedness of $1.9 billion, and that our annual operating expenses would remain at the levels set forth in the table above and that we would pay the costs shown in the table above.


	1 Year		3 Years		5 Years		10 Years
Ongoing Preferred Stock Offerings(1) - You would pay the following expenses on a $1,000 investment in shares of our common stock, assuming a 5% annual return on our portfolio*	$	171	$	388	$	572	$	919
Ongoing Preferred Stock Offerings(1) - You would pay the following expenses on a $1,000 investment in shares of our common stock, assuming a 5% annual return on our portfolio**	$	180	$	410	$	601	$	949

* Assumes that we will not realize any capital gains computed net of all realized capital losses and unrealized capital depreciation on our portfolio.

** Assumes no unrealized capital depreciation or realized capital losses and 5% annual return on our portfolio resulting entirely from net realized capital gains (and therefore subject to the capital gains incentive fee).

While the example assumes, as required by the SEC, a 5% annual return on our portfolio, our performance will vary and may result in a return greater or less than 5%. The income incentive fee under our Investment Advisory Agreement with Prospect Capital Management is unlikely to be material assuming a 5% annual return on our portfolio and is not included in the example. If we achieve sufficient returns on our portfolio, including through the realization of capital gains, to trigger an incentive fee of a material amount, our distributions to our common stockholders and our expenses would likely be higher. In addition, while the example assumes reinvestment of all dividends and other distributions at NAV, common stockholders that participate in our common stock dividend reinvestment plan will receive a number of shares of our common stock determined by dividing the total dollar amount of the distribution payable to a participant by 95% of the market price per share of our common stock at the close of trading on the valuation date for the distribution.

This example and the expenses in the table above should not be considered a representation of our future expenses. Actual expenses (including the cost of debt, if any, and other expenses) may be greater or less than those shown.

(1) Includes up to a 7.0% selling commission on the $25.00 per share (the “Stated Value”) paid by the Company and a dealer manager fee equal to 3.0% of the Stated Value paid by the Company. Reductions in selling commissions will be reflected in reduced public offering prices as described in the “Plan of Distribution” section of the applicable prospectus supplement and the net proceeds to us will not be impacted by such reductions; therefore, we will bear a reduction in net proceeds to us up to 7.0% of the Stated Value on all A Shares although the selling commission compensation paid by us to our dealer manager may represent less than 7.0% of the Stated Value. We may, through the Holder Optional Conversion Fee, recoup a portion of the Sales Load if stockholders exercise a Holder Optional Conversion (as defined in the prospectus supplement relating to the applicable offering) of their Preferred Stock prior to the 5-year anniversary of the original issue date. The Holder Optional Conversion Fee is 9.00% of the maximum public offering price disclosed herein prior to the first anniversary of the issuance of such Preferred Stock, 8.00% of the maximum public offering price disclosed herein on or after the first anniversary but prior to the second anniversary, 7.00% of the maximum public offering price disclosed herein on or after the second anniversary but prior to the third anniversary, 6.00% of the maximum public offering price disclosed herein on or after the third anniversary but prior to the fourth anniversary, 5.00% of the maximum public offering price disclosed herein on or after the fourth anniversary but prior to the fifth anniversary and 0.00% on or after the fifth anniversary.

(2) Includes a dealer manager fee equal to 3.0% of the Stated Value paid by the Company.

(3) Includes up to a 4.875% selling commission on the $25.00 per share (the “Stated Value”) paid by the Company and a dealer manager fee equal to 0.125% of the Stated Value paid by the Company. For the AA1 Shares we may, through the Holder Optional Conversion Fee, recoup a portion of the Sales Load if stockholders exercise a Holder Optional Conversion (as defined in the prospectus supplement relating to the applicable offering) of their Preferred Stock prior to the 5-year anniversary of the original issue date. The Holder Optional Conversion Fee is 9.00% of the maximum public offering price disclosed herein prior to the first anniversary of the issuance of such Preferred Stock, 8.00% of the maximum public offering price disclosed herein on or after the first anniversary but prior to the second anniversary, 7.00% of the maximum public offering price disclosed herein on or after the second anniversary but prior to the third anniversary, 6.00% of the maximum public offering price disclosed herein on or after the third anniversary but prior to the fourth anniversary, 5.00% of the maximum public offering price disclosed herein on or after the fourth anniversary but prior to the fifth anniversary and 0.00% on or after the fifth anniversary.

(4) The selling commission and dealer manager fee, when combined with organization and offering expenses (including due diligence expenses and fees for establishing servicing arrangements for new stockholder accounts), are not expected to exceed 11.5% of the gross offering proceeds. Our Board of Directors may, in its discretion, authorize the Company to incur underwriting and other offering expenses in excess of 11.5% of the gross offering proceeds. In no event will the combined selling commission, dealer manager fee and offering expenses exceed FINRA’s limit on underwriting and other offering expenses.

(5) The selling commission and dealer manager fee, when combined with organization and offering expenses (including due diligence expenses), are not expected to exceed 6.0% of the gross offering proceeds. Our Board of Directors may, in its discretion, authorize the Company to incur underwriting and other offering expenses in excess of 6.0% of the gross offering proceeds. In no event will the combined selling commission, dealer manager fee and offering expenses exceed FINRA’s limit on underwriting and other offering expenses.

(6) The expenses of the Preferred DRIP are included in “other expenses.” See “Capitalization” in the applicable prospectus supplement.

(7) Our base management fee is 2% of our gross assets (which include any amount borrowed, i.e., total assets without deduction for any liabilities, including any borrowed amounts for non-investment purposes, for which purpose we have not and have no intention of borrowing). Although no plans are in place to borrow the full amount under our line of credit, assuming that we borrowed $1.6 billion, the 2% management fee of gross assets equals approximately 4.79% of net assets.

(8) Based on our net investment income and realized capital gains, less realized and unrealized capital losses, earned on our portfolio for the year ended September 30, 2022, all of which consisted of an income incentive fee. This historical amount has been adjusted to reflect the issuance of 70,187,000 shares of 5.50% Preferred Stock. The capital gain incentive fee is paid without regard to pre-incentive fee income. For a more detailed discussion of the calculation of the two-part incentive fee, see “Management Services-Investment Advisory Agreement” in the applicable prospectus.

(9) As of September 30, 2022, we had $1.9 billion outstanding of Unsecured Notes (as defined below) in various maturities, ranging from March 15, 2023 to March 15, 2052, and interest rates, ranging from 1.50% to 6.625%, some of which are convertible into shares of the Company’s common stock at various conversion rates.

(10) “Other expenses” are based on estimated amounts for the current fiscal year. The amount shown above represents annualized expenses during our year ended September 30, 2022 representing all of our estimated recurring operating expenses (except fees and expenses reported in other items of this table) that are deducted from our operating income and reflected as expenses in our Statement of Operations. The estimate of our overhead expenses, including payments under an administration agreement with Prospect Administration, or the Administration Agreement is based on our projected allocable portion of overhead and other expenses incurred by Prospect Administration in performing its obligations under the Administration Agreement. See “Business-Management Services-Administration Agreement” in the applicable prospectus.

(11) If all 70,187,000 shares of 5.50% Preferred Stock were converted into common stock and assuming all the Series A1 and Series AA1 Preferred Stock pay a Holder Optional Conversion Fee of 9.00% of the maximum public offering price disclosed within the applicable prospectus supplement and are converted at a conversion rate based on the 5-day VWAP of our common stock on September 30, 2022, which was $6.57, then management fees would be 3.30%, incentive fees payable under our Investment Advisory Agreement would be 1.54%, total advisory fees would be 4.84%, total interest expenses would be 3.03%, other expenses would be 0.68%, and total annual expenses would be 8.55% of net assets attributable to our common stock. The actual 5-day VWAP of our common stock on a conversion date may be more or less than $6.57, which may result in fees that are higher or lower than those described herein. These figures are based on the same assumptions described in the other notes to this fee table.

(12) Based on the 5.50% per annum dividend rate applicable to the A1 Shares, M1 Shares, M2 Shares, AA1 Shares, MM1 Shares, and A2 Shares. Also based on the 5.35% per annum dividend rate applicable to the A Shares. Other series of preferred stock, including other series of preferred stock being sold in different offerings, may bear different annual dividend rates. No dividend will be paid on shares of Preferred Stock after they have been converted to shares of common stock.

(13) The indirect expenses associated with the Company’s investments in collateralized loan obligations are not included in the fee table presentation, but if such expenses were included in the fee table presentation then the Company’s total annual expenses would have been 12.99%, or 15.69% after dividends on Preferred Stock.

Purpose of Fee Table , Note [Text Block]

The following tables are intended to assist you in understanding the costs and expenses that an investor in shares of common stock will bear directly or indirectly. We caution you that some of the percentages indicated in the table below are estimates and may vary. These tables are based on our assets and common stock outstanding as of September 30, 2022, except that we assume that we have issued $1.75 billion in 5.50% Preferred Stock paying dividends of 5.50% per annum, in addition to our $0.15 billion of 5.35% Preferred Stock paying dividends of 5.35% per annum, and that we have borrowed $1.6 billion under our credit facility, which is the maximum amount available under the credit facility with the current levels of other debt, in addition to our other indebtedness of $1.9 billion. Except where the context suggests otherwise, any reference to fees or expenses paid by “you” or “us” or that “we” will pay fees or expenses, the Company will pay such fees and expenses out of our net assets and, consequently, you will indirectly bear such fees or expenses as an investor in the Company’s common stock. However, you will not be required to deliver any money or otherwise bear personal liability or responsibility for such fees or expenses.

General Description of Registrant [Abstract]

Investment Objectives and Practices [Text Block]

Our investment objective is to generate both current income and long-term capital appreciation through debt and equity investments. We invest primarily in senior and subordinated secured debt and equity of private companies in need of capital for acquisitions, divestitures, growth, development, recapitalizations and other purposes. We work with the management teams or financial sponsors to seek investments with historical cash flows, asset collateral or contracted pro-forma cash flows.

We currently have four primary strategies that guide our origination of investment opportunities: (1) lending to companies, including companies controlled by private equity sponsors and not controlled by private equity sponsors, and including both directly-originated loans and syndicated loans, (2) lending to companies and purchasing controlling equity positions in such companies, including both operating companies and financial services companies, (3) purchasing controlling equity positions and lending to real estate companies, and (4) investing in structured credit. We may also invest in other strategies and opportunities from time to time that we view as attractive. We continue to evaluate other origination strategies in the ordinary course of business with no specific top-down allocation to any single origination strategy.

Lending to Companies - We make directly-originated, agented loans to companies, including companies which are controlled by private equity sponsors and companies that are not controlled by private equity sponsors (such as companies that are controlled by the management team, the founder, a family or public shareholders). This debt can take the form of first lien, second lien, unitranche or unsecured loans. These loans typically have equity subordinate to our loan position. We may also purchase selected equity co-investments in such companies. In addition to directly-originated, agented loans, we also invest in senior and secured loans syndicated loans and high yield bonds that have been sold to a club or syndicate of buyers, both in the primary and secondary markets. These investments are often purchased with a long term, buy-and-hold outlook, and we often look to provide significant input to the transaction by providing anchoring orders. Historically, this strategy has comprised approximately 40%-60% of our portfolio.

Lending to Companies and Purchasing Controlling Equity Positions in Such Companies - This strategy involves purchasing senior and secured yield-producing debt and controlling equity positions in operating companies across various industries. We believe this strategy provides enhanced certainty of closure to sellers and the opportunity for management to continue on in their current roles. These investments are often structured in tax-efficient partnerships, enhancing returns. Historically, this strategy has comprised approximately 15%-25% of our portfolio.

Purchasing Controlling Equity Positions and Lending to Real Estate Companies - We purchase debt and controlling equity positions in tax-efficient real estate investment trusts (“REIT” or “REITs”). The real estate investments of National Property REIT Corp. (“NPRC”) are in various classes of developed and occupied real estate properties that generate current yields, including multi-family properties, and student housing. NPRC seeks to identify properties that have historically significant occupancy rates and recurring cash flow generation. NPRC generally co-invests with established and experienced property management teams that manage such properties after acquisition. Additionally, NPRC makes investments in rated secured structured notes (primarily debt of structured credit). NPRC also purchases loans originated by certain consumer loan facilitators. It purchases each loan in its entirety (i.e., a “whole loan”). The borrowers are consumers, and the loans are typically serviced by the facilitators of the loans. Historically, this overall investment strategy has comprised approximately 10%-20% of our business.

Investing in Structured Credit - We make investments in structured credit, often taking a significant position in subordinated structured notes (equity) and rated secured structured notes (debt). The underlying portfolio of each structured credit investment is diversified across approximately 100 to 200 broadly syndicated loans and does not have direct exposure to real estate, mortgages, or consumer-based credit assets. The structured credit portfolios in which we invest are managed by established collateral management teams with many years of experience in the industry. Historically, this overall strategy has comprised approximately 10%-20% of our portfolio.

We invest primarily in first and second lien secured loans and unsecured debt, which in some cases includes an equity component. First and second lien secured loans generally are senior debt instruments that rank ahead of unsecured debt of a given portfolio company. These loans also have the benefit of security interests on the assets of the portfolio company, which may rank ahead of or be junior to other security interests. Our investments in structured credit are subordinated to senior loans and are generally unsecured. We invest in debt and equity positions of structured credit which are a form of securitization in which the cash flows of a portfolio of loans are pooled and passed on to different classes of owners in various tranches. Our structured credit investments are derived from portfolios of corporate debt securities which are generally risk rated from BB to B.

We hold many of our control investments in a two-tier structure consisting of a holding company and one or more related operating companies for tax purposes. These holding companies serve various business purposes including concentration of management teams, optimization of third-party borrowing costs, improvement of supplier, customer, and insurance terms, and enhancement of co-investments by the management teams. In these cases, our investment, which is generally equity in the holding company, the holding company’s equity investment in the operating company and any debt from us directly to the operating company structure represents our total exposure for the investment. As of September 30, 2022, as shown in our Consolidated Schedule of Investments, the cost basis and fair value of our investments in controlled companies was $2,786,356 and $3,444,478, respectively. This structure gives rise to several of the risks described in our public documents and highlighted elsewhere in this Quarterly Report. We consolidate all wholly owned and substantially wholly owned holding companies formed by us for the purpose of holding our controlled investments in operating companies. There is no significant effect of consolidating these holding companies as they hold minimal assets other than their investments in the controlled operating companies. Investment company accounting prohibits the consolidation of any operating companies.

Long Term Debt [Table Text Block]

Capitalization

Our investment activities are capital intensive and the availability and cost of capital is a critical component of our business. We capitalize our business with a combination of debt and equity. Our debt as of September 30, 2022 consists of: a Revolving Credit Facility availing us of the ability to borrow debt subject to borrowing base determinations; Convertible Notes which we issued in March 2019; Public Notes which we issued in March 2013, October 2018, January 2021, May 2021 and September 2021; and Prospect Capital InterNotes® which we issue from time to time. As of September 30, 2022, our equity capital is comprised of common and preferred equity.

We may from time to time seek to cancel or purchase our outstanding debt through cash purchases and/or exchanges, in open market purchases, privately negotiated transactions or otherwise. The amounts involved may be material. In addition, we may from time to time enter into additional debt facilities, increase the size of existing facilities or issue additional debt securities, including secured debt, unsecured debt and/or debt securities convertible into common stock. Any such purchases or exchanges of outstanding debt would be subject to prevailing market conditions, our liquidity requirements, contractual and regulatory restrictions and other factors.

Historically, we have funded a portion of our cash needs through borrowings from banks, issuances of senior securities, including secured, unsecured and convertible debt securities, or issuances of common equity. For flexibility, we maintain a universal shelf registration statement that allows for the public offering and sale of our debt securities, common stock, preferred stock, subscription rights, and warrants and units to purchase such securities up to an indeterminate amount. We may from time to time issue securities pursuant to the shelf registration statement or otherwise pursuant to private offerings. The issuance of debt or equity securities will depend on future market conditions, funding needs and other factors and there can be no assurance that any such issuance will occur or be successful.

Each of our Convertible Notes, Public Notes and Prospect Capital InterNotes® (collectively, our “Unsecured Notes”) are our general, unsecured obligations and rank equal in right of payment with all of our existing and future unsecured indebtedness and will be senior in right of payment to any of our subordinated indebtedness that may be issued in the future. The Unsecured Notes are effectively subordinated to our existing secured indebtedness, such as our credit facility, and future secured indebtedness to the extent of the value of the assets securing such indebtedness and structurally subordinated to any existing and future liabilities and other indebtedness of any of our subsidiaries.

Risks Relating to Our Investments

Investments in covenant-lite loans may expose us to different and increased risks.

Although we generally expect the transaction documentation of some portion of our investments to include covenants and other structural protections, a significant portion of our investments may be composed of so-called “covenant-lite loans.” Generally, covenant-lite loans do not have certain maintenance covenants that would require the issuer to maintain debt service or other financial ratios. Ownership of covenant-lite loans may expose us to different risks, including with respect to liquidity, price volatility and ability to restructure loans, than is the case with loans that have financial maintenance covenants. As a result, our exposure to losses from these loans may be increased. In addition, in the current economic environment, the market prices of covenant-lite loans may be depressed.

Securities Risk [Member]

General Description of Registrant [Abstract]

Risk [Text Block]

Senior securities, including debt and preferred equity, expose us to additional risks, including the typical risks associated with leverage and could adversely affect our business, financial condition and results of operations.

We use our revolving credit facility to leverage our portfolio and we expect in the future to borrow from and issue senior debt securities to banks and other lenders and may securitize certain of our portfolio investments. We also have the Unsecured Notes outstanding and have launched a convertible preferred share offering program, which are forms of leverage and are senior in payment rights to our common stock.

Business development companies are generally able to issue senior securities such that their asset coverage, as defined in the 1940 Act, equals at least 200% of gross assets less all liabilities and indebtedness not represented by senior securities, after each issuance of senior securities. In March 2018, the Small Business Credit Availability Act added Section 61(a)(2) to the 1940 Act, a successor provision to Section 61(a)(1) referenced therein, which reduces the asset coverage requirement applicable to business development companies from 200% to 150% so long as the business development company meets certain disclosure requirements and obtains certain approvals. On May 5, 2020, the Company's stockholders voted to approve the application of the reduced asset coverage requirements in Section 61(a)(2) to the Company effective as of May 6, 2020. As a result of the stockholder approval, effective May 6, 2020, the asset coverage ratio under the 1940 Act applicable to the Company decreased to 150% from 200%. In other words, under the 1940 Act, the Company is now able to borrow $2 for investment purposes for every $1 of investor equity, as opposed to borrowing $1 for investment purposes for every $1 of investor equity. As a result, the Company will be able to incur additional indebtedness in the future and investors in the Company may face increased investment risk. In addition, the Company’s management fee payable to the Investment Adviser is based on the Company's average adjusted gross assets, which includes leverage and, as a result, if the Company incurs additional leverage, management fees paid to the Investment Adviser would increase.

With certain limited exceptions, as a BDC, we are only allowed to borrow amounts or otherwise issue senior securities such that our asset coverage, as defined in the 1940 Act, is at least 150% after such borrowing or other issuance. The amount of leverage

that we employ will depend on the Investment Adviser’s and our Board of Directors’ assessment of market conditions and other factors at the time of any proposed borrowing. There is no assurance that a leveraging strategy will be successful. Leverage involves risks and special considerations for stockholders, any of which could adversely affect our business, financial condition and results of operations, including the following:

•A likelihood of greater volatility in the net asset value and market price of our common stock;

•Diminished operating flexibility as a result of asset coverage or investment portfolio composition requirements required by lenders or investors that are more stringent than those imposed by the 1940 Act;

•The possibility that investments will have to be liquidated at less than full value or at inopportune times to comply with debt covenants or to pay interest or dividends on the leverage;

•Increased operating expenses due to the cost of leverage, including issuance and servicing costs;

•Convertible or exchangeable securities, such as the Convertible Notes outstanding or those issued in the future (including the Preferred Stock (as defined herein)) may have rights, preferences and privileges more favorable than those of our common stock including, the case of the Preferred Stock, the statutory right under the 1940 Act to vote, as a separate class, on the election of two of our directors and approval of certain fundamental transactions in certain circumstances;

•Subordination to lenders’ superior claims on our assets as a result of which lenders will be able to receive proceeds available in the case of our liquidation before any proceeds will be distributed to our stockholders;

•Difficulty meeting our payment and other obligations under the Unsecured Notes and our other outstanding debt or preferred equity;

•The occurrence of an event of default if we fail to comply with the financial and/or other restrictive covenants contained in our debt agreements, including the credit agreement and each indenture governing the Unsecured Notes, which event of default could result in all or some of our debt becoming immediately due and payable;

•Reduced availability of our cash flow to fund investments, acquisitions and other general corporate purposes, and limiting our ability to obtain additional financing for these purposes;

•The risk of increased sensitivity to interest rate increases on our indebtedness with variable interest rates, including borrowings under our amended senior credit facility; and

•Reduced flexibility in planning for, or reacting to, and increasing our vulnerability to, changes in our business, the industry in which we operate and the general economy.

For example, the amount we may borrow under our revolving credit facility is determined, in part, by the fair value of our investments. If the fair value of our investments declines, we may be forced to sell investments at a loss to maintain compliance with our borrowing limits. Other debt facilities we may enter into in the future may contain similar provisions. Any such forced sales would reduce our net asset value and also make it difficult for the net asset value to recover. The Investment Adviser and our Board of Directors in their best judgment nevertheless may determine to use leverage if they expect that the benefits to our stockholders of maintaining the leveraged position will outweigh the risks.

•In addition, our ability to meet our payment and other obligations of the Preferred Stock, the Unsecured Notes and our credit facility depends on our ability to generate significant cash flow in the future. This, to some extent, is subject to general economic, financial, competitive, legislative and regulatory factors as well as other factors that are beyond our control. We cannot provide assurance that our business will generate cash flow from operations, or that future borrowings will be available to us under our existing credit facility or otherwise, in an amount sufficient to enable us to meet our payment obligations under the Preferred Stock, the Unsecured Notes and our other debt and to fund other liquidity needs. If we are not able to generate sufficient cash flow to service our debt and preferred equity obligations, we may need to refinance or restructure our debt or preferred equity, including the Unsecured Notes, sell assets, reduce or delay capital investments, or seek to raise additional capital. If we are unable to implement one or more of these alternatives, we may not be able to meet our payment obligations under the Preferred Stock, the Unsecured Notes and our other debt.

Revolving Credit Facility

On May 15, 2007, we formed our wholly owned subsidiary, Prospect Capital Funding LLC (“PCF”), a Delaware limited liability company and a bankruptcy remote special purpose entity, which holds certain of our portfolio loan investments that are used as collateral for the revolving credit facility at PCF. Since origination of the revolving credit facility, we have renegotiated the terms and extended the commitments of the revolving credit facility several times. Most recently, effective September 15, 2022, we completed an extension and upsizing of the revolving credit facility (the “2022 Facility” or the “Revolving Credit Facility”). The lenders have extended commitments of $1,634,000 as of September 30, 2022. The 2022 Facility includes an accordion feature which allows commitments to be increased up to $2,000,000 in the aggregate. The extension and upsizing of the Revolving Credit Facility extends the maturity date to September 15, 2027 and the revolving period through September 15, 2026, followed by an additional one-year amortization period, with distributions allowed to Prospect after the completion of the revolving period. During such one-year amortization period, all principal payments on the pledged assets will be applied to reduce the balance. At the end of the one-year amortization period, the remaining balance will become due.

As of September 30, 2022 and June 30, 2022, we had $659,623 and $660,536, respectively, available to us for borrowing under the Revolving Credit Facility, net of $799,851 and $839,464 outstanding borrowings as of the respective balance sheet dates. Refer to Note 4. Revolving Credit Facility within our consolidated financial statements for additional details.

On October 30, 2020, and amended on February 18, 2022, we entered into a Dealer Manager Agreement with InspereX LLC, pursuant to which InspereX LLC has agreed to serve as the Company’s agent and dealer manager for the Company’s offering of up to 10,000,000 shares, par value $0.001 per share, of preferred stock, with a liquidation preference of $25.00 per share. Such preferred stock will initially be issued in multiple series, including the 5.50% Series AA1 Preferred Stock (the “Series AA1 Preferred Stock”) and the 5.50% Series MM1 Preferred Stock (the “Series MM1 Preferred Stock” and together with the Series M1 Preferred Stock and the Series M2 Preferred Stock, the “Series M Preferred Stock”). In connection with such offering, on October 30, 2020 and February 17, 2022, we filed Articles Supplementary with the SDAT, reclassifying and designating an additional 40,000,000 shares of the Company’s authorized and unissued shares of common stock into shares of preferred stock as Convertible Preferred Stock. On May 19, 2021, we entered into an Underwriting Agreement with UBS Securities LLC, relating to the offer and sale of 187,000 shares, par value $0.001 per share, of 5.50% Series A2 Preferred Stock, with a liquidation preference of $25.00 per share (the “Series A2 Preferred Stock”, and together with the Series A1 Preferred Stock, Series M1 Preferred Stock, Series M2 Preferred Stock, Series AA1 Preferred Stock, and Series MM1 Preferred Stock, the “5.50% Preferred Stock”). The issuance of the Series A2 Preferred Stock settled on May 26, 2021. In connection with such offering, on May 19, 2021, we filed Articles Supplementary with the SDAT, reclassifying and designating an additional 1,000,000 shares of the Company’s authorized and unissued shares of common stock into shares of preferred stock as Convertible Preferred Stock.

In connection with the offerings of the 5.50% Preferred Stock, we adopted and amended, respectively, a preferred stock dividend reinvestment plan (the “Preferred Stock Plan” or the “Preferred Stock DRIP”), pursuant to which holders of the 5.50% Preferred Stock will have dividends on their 5.50% Preferred Stock automatically reinvested in additional shares of such 5.50% Preferred Stock at a price per share of $25.00, if they elect.

Each series of 5.50% Preferred Stock ranks (with respect to the payment of dividends and rights upon liquidation, dissolution or winding up) (a) senior to our common stock, (b) on parity with each other series of our preferred stock, and (c) junior to our existing and future secured and unsecured indebtedness. See Note 8, Fair Value and Maturity of Debt Outstanding for further discussion on our senior securities.

At any time prior to the listing of the 5.50% Preferred Stock on a national securities exchange, shares of the 5.50% Preferred Stock are convertible, at the option of the holder of the 5.50% Preferred Stock (the “Holder Optional Conversion”). We will settle any Holder Optional Conversion by paying or delivering, as the case may be, (A) any portion of the Settlement Amount

(as defined below) that we elect to pay in cash and (B) a number of shares of our common stock at a conversion rate equal to (1) (a) the Settlement Amount, minus (b) any portion of the Settlement Amount that we elect to pay in cash, divided by (2) the arithmetic average of the daily volume weighted average price of shares of our common stock over each of the five consecutive trading days ending on the Holder Conversion Exercise Date (such arithmetic average, the “5-day VWAP”). For the Series A1 Preferred Stock, the Series AA1 Preferred Stock, and the Series A2 Preferred Stock, “Settlement Amount” means (A) $25.00 per share (the “Stated Value”), plus (B) unpaid dividends accrued to, but not including, the Holder Conversion Exercise Date, minus (C) the applicable 5.50% Holder Optional Conversion Fee for the respective Holder Conversion Deadline. For the Series M Preferred Stock, “Settlement Amount” means (A) the Stated Value, plus (B) unpaid dividends accrued to, but not including, the Holder Conversion Exercise Date, minus (C) the applicable Series M Clawback, if any. “Series M Clawback”, if applicable, means an amount equal to the aggregate amount of all dividends, whether paid or accrued, on such share of Series M Stock in the three full months prior to the Holder Conversion Exercise Date. Subject to certain limited exceptions, we will not pay any portion of the Settlement Amount in cash (other than cash in lieu of fractional shares of our common stock) until the five year anniversary of the date on which a share of 5.50% Preferred Stock has been issued. Beginning on the five year anniversary of the date on which a share of 5.50% Preferred Stock is issued, we may elect to settle all or a portion of any Holder Optional Conversion in cash without limitation or restriction. The right of holders to convert a share of 5.50% Preferred Stock will terminate upon the listing of such share on a national securities exchange.

Subject to certain limited exceptions allowing earlier redemption, beginning on the earlier of the five year anniversary of the date on which a share of 5.50% Preferred Stock has been issued, or, for listed shares of 5.50% Preferred Stock, five years from the earliest date on which any series that has been listed was first issued (the earlier of such dates, the “Redemption Eligibility Date”), such share of 5.50% Preferred Stock may be redeemed at any time or from time to time at our option (the “Issuer Optional Redemption”), at a redemption price of 100% of the Stated Value of the shares of 5.50% Preferred Stock to be redeemed plus unpaid dividends accrued to, but not including, the date fixed for redemption.

Subject to certain limitations, each share of 5.50% Preferred Stock may be converted at our option (the “Issuer Optional Conversion”). We will settle any Issuer Optional Conversion by paying or delivering, as the case may be, (A) any portion of the IOC Settlement Amount (as defined below) that we elect to pay in cash and (B) a number of shares of our common stock at a conversion rate equal to (1) (a) the IOC Settlement Amount, minus (b) any portion of the IOC Settlement Amount that we elect to pay in cash, divided by (2) the 5-day VWAP, subject to our ability to obtain or maintain any stockholder approval that may be required under the 1940 Act to permit us to sell our common stock below net asset value if the 5-day VWAP represents a discount to our net asset value per share of common stock. For the 5.50% Preferred Stock, “IOC Settlement Amount” means (A) the Stated Value, plus (B) unpaid dividends accrued to, but not including, the date fixed for conversion. In connection with an Issuer Optional Conversion, we will use commercially reasonable efforts to obtain or maintain any stockholder approval that may be required under the 1940 Act to permit us to sell our common stock below net asset value. If we do not have or obtain any required stockholder approval under the 1940 Act to sell our common stock below net asset value and the 5-day VWAP is at a discount to our net asset value per share of common stock, we will settle any conversions in connection with an Issuer Optional Conversion by paying or delivering, as the case may be, (A) any portion of the IOC Settlement Amount that we elect to pay in cash and (B) a number of shares of our common stock at a conversion rate equal to (1) (a) the IOC Settlement Amount, minus (b) any portion of the IOC Settlement Amount that we elect to pay in cash, divided by (2) the NAV per share of common stock at the close of business on the business day immediately preceding the date of conversion. We will not pay any portion of the IOC Settlement Amount from an Issuer Optional Conversion in cash (other than cash in lieu of fractional shares of our common stock) until the Redemption Eligibility Date. Beginning on the Redemption Eligibility Date, we may elect to settle any Issuer Optional Conversion in cash without limitation or restriction. In the event that we exercise an Issuer Optional Conversion with respect to any shares of 5.50% Preferred Stock, the holder of such 5.50% Preferred Stock may instead elect a Holder Optional Conversion with respect to such 5.50% Preferred Stock provided that the date of conversion for such Holder Optional Conversion would occur prior to the date of conversion for an Issuer Optional Conversion.

On July 12, 2021, we entered into an underwriting agreement by and among us, Prospect Capital Management L.P., Prospect Administration LLC, and Morgan Stanley & Co. LLC, RBC Capital Markets, LLC and UBS Securities LLC, as representatives of the underwriters, relating to the offer and sale of 6,000,000 shares, or $150,000 in aggregate liquidation preference, of our 5.35% Series A Fixed Rate Cumulative Perpetual Preferred Stock, par value $0.001 per share (the “Series A Preferred Stock” or “5.35% Preferred Stock”), at a public offering price of $25.00 per share. Pursuant to the Underwriting Agreement, we also granted the underwriters a 30-day option to purchase up to an additional 900,000 shares of Series A Preferred Stock solely to cover over-allotments. The offer settled on July 19, 2021, and no additional shares of the Series A Preferred Stock were issued pursuant to the option. In connection with such offering, on July 15, 2021, we filed Articles Supplementary with SDAT, reclassifying and designating 6,900,000 shares of the Company’s authorized and unissued shares of Common Stock into shares of Series A Preferred Stock.

The Series A Preferred Stock ranks (with respect to the payment of dividends and rights upon liquidation, dissolution or winding up) (a) senior to our common stock, (b) on parity with each other series of our preferred stock, and (c) junior to our existing and future secured and unsecured indebtedness. See Note 8, Fair Value and Maturity of Debt Outstanding for further discussion on our senior securities.

Subject to certain limited exceptions allowing earlier redemption, at any time after the close of business on July 19, 2026 (any such date, an “Optional Redemption Date”), at our sole option, we may redeem the Series A Preferred Stock in whole or, from time to time, in part, out of funds legally available for such redemption, at a price per share equal to the liquidation preference of $25.00 per share, plus an amount equal to all unpaid dividends on such shares (whether or not earned or declared, but excluding interest thereon) accumulated up to, but excluding, the date fixed for redemption. We may also redeem the Series A Preferred Stock at any time, in whole or, from time to time, in part, including prior to the Optional Redemption Date, pro rata, based on liquidation preference, with all other series of our then outstanding preferred stock, in the event that our Board determines to redeem any series of our preferred stock, in whole or, from time to time, in part, because such redemption is deemed necessary by the Board to comply with the asset coverage requirements of the 1940 Act or for us to maintain RIC status.

In the event of a Change of Control Triggering Event (as defined below), we may, at our option, exercise our special optional redemption right to redeem the Series A Preferred Stock, in whole or in part, within 120 days after the first date on which such Change of Control Triggering Event has occurred by paying the liquidation preference, plus an amount equal to all unpaid dividends on such shares (whether or not earned or declared, but excluding interest thereon) accumulated up to, but excluding, the date fixed for such redemption. To the extent that we exercise our optional redemption right or our special optional redemption right relating to the Series A Preferred Stock, the holders of Series A Preferred Stock will not be permitted to exercise the conversion right described below in respect of their shares called for redemption.

Except to the extent that we have elected to exercise our optional redemption right or our special optional redemption right by providing notice of redemption prior to the Change of Control Conversion Date (as defined below), upon the occurrence of a Change of Control Triggering Event, each holder of Series A Preferred Stock will have the right to convert some or all of the Series A Preferred Stock held by such holder on the Change of Control Conversion Date into a number of our shares of common stock per Series A Preferred Stock to be converted equal to the lesser of:

•the quotient obtained by dividing (i) the sum of the Liquidation Preference per share plus an amount equal to all unpaid dividends thereon (whether or not earned or declared, but excluding interest thereon) accumulated up to, but excluding, the Change of Control Conversion Date (unless the Change of Control Conversion Date is after a Record Date for a Series A Preferred Stock dividend payment and prior to the corresponding Series A Preferred Stock dividend payment date, in which case no additional amount for such accrued and unpaid dividends will be included in this sum) by (ii) the Common Stock Price (as defined below); and

•6.03865, subject to certain adjustments,

subject, in each case, to provisions for the receipt of alternative consideration upon conversion as described in the applicable prospectus supplement.

If we have provided or provide a redemption notice with respect to some or all of the Series A Preferred Stock, holders of any Series A Preferred Stock that we have called for redemption will not be permitted to exercise their Change of Control Conversion Right in respect of any of their Series A Preferred Stock that have been called for redemption, and any Series A Preferred Stock subsequently called for redemption that have been tendered for conversion will be redeemed on the applicable date of redemption instead of converted on the Change of Control Conversion Date.

For purposes of the foregoing discussion of a redemption upon the occurrence of a Change of Control Triggering Event, the following definitions are applicable:

“Change of Control Triggering Event” means the occurrence of any of the following:

•the direct or indirect sale, lease, transfer, conveyance or other disposition (other than by way of merger or consolidation and other than an Excluded Transaction) in one or a series of related transactions, of all or substantially all of the assets of the Company and its Controlled Subsidiaries taken as a whole to any “person” or “group” (as those terms are used in Section 13(d)(3) of the Exchange Act) (other than to any Permitted Holders); provided that, for the avoidance of doubt, a pledge of assets pursuant to any of our secured debt instruments or the secured debt instruments of our Controlled Subsidiaries shall not be deemed to be any such sale, lease, transfer, conveyance or disposition; or

•the consummation of any transaction (including, without limitation, any merger or consolidation and other than an Excluded Transaction) the result of which is that any “person” or “group” (as those terms are used in Section 13(d)(3) of the Exchange Act) (other than any Permitted Holders) becomes the “beneficial owner” (as defined in Rules 13d-3 and 13d-5 under the Exchange Act), directly or indirectly, of more than 50% of our outstanding Voting Stock, measured by voting power rather than number of shares.

Notwithstanding the foregoing, the consummation of any of the transactions referred to in the bullet points above will not be deemed a Change of Control Triggering Event if we or the acquiring or surviving consolidated entity has or continues to have a class of common securities (or ADRs representing such securities) listed on the NYSE, the NYSE American or NASDAQ, or

listed or quoted on an exchange or quotation system that is a successor to the NYSE, the NYSE American or NASDAQ, or is otherwise listed or quoted on a national securities exchange.

The “Change of Control Conversion Date” is the date the shares of Series A Preferred Stock are to be converted, which will be a business day selected by us that is no fewer than 20 days nor more than 35 days after the date on which we provide the notice described above to the holders of Series A Preferred Stock.

The “Common Stock Price” will be (i) if the consideration to be received in the Change of Control Triggering Event by the holders of our common stock is solely cash, the amount of cash consideration per share of our common stock or (ii) if the consideration to be received in the Change of Control Triggering Event by holders of our common stock is other than solely cash (x) the average of the closing sale prices per share of our common stock (or, if no closing sale price is reported, the average of the closing bid and ask prices or, if more than one in either case, the average of the average closing bid and the average closing ask prices) for the ten consecutive trading days immediately preceding, but not including, the effective date of the Change of Control Triggering Event as reported on the principal U.S. securities exchange on which our common stock is then traded, or (y) the average of the last quoted bid prices for our common stock in the over-the-counter market as reported by OTC Markets Group Inc. or similar organization for the ten consecutive trading days immediately preceding, but not including, the effective date of the Change of Control Triggering Event, if our common stock is not then listed for trading on a U.S. securities exchange.

“Controlled Subsidiary” means any of our subsidiaries, 50% or more of the outstanding equity interests of which are owned by us and our direct or indirect subsidiaries and of which we possess, directly or indirectly, the power to direct or cause the direction of the management or policies, whether through the ownership of voting equity interests, by agreement or otherwise.

“Excluded Transaction” means (i) any transaction that does not result in any reclassification, conversion, exchange or cancellation of all or substantially all of the outstanding shares of our Voting Stock; (ii) any changes resulting from a subdivision or combination or a change solely in par value; (iii) any transaction where the shares of our Voting Stock outstanding immediately prior to such transaction constitute, or are converted into or exchanged for, a majority of the Voting Stock of the surviving “person” (as that term is used in Section 13(d)(3) of the Exchange Act) or any direct or indirect parent company of the surviving “person” (as that term is used in Section 13(d)(3) of the Exchange Act) immediately after giving effect to such transaction; (iv) any transaction if (A) we become a direct or indirect wholly-owned subsidiary of a holding company and (B)(1) the direct or indirect holders of the Voting Stock of such holding company immediately following that transaction are substantially the same as the holders of our Voting Stock immediately prior to that transaction or (2) immediately following that transaction no “person” (as that term is used in Section 13(d)(3) of the Exchange Act) is the beneficial owner, directly or indirectly, of more than 50% of the Voting Stock of such holding company; or (v) any transaction primarily for the purpose of changing our jurisdiction of incorporation or form of organization.

“Permitted Holders” means (i) us, (ii) one or more of our Controlled Subsidiaries and (iii) Prospect Capital Management or any affiliate of Prospect Capital Management that is organized under the laws of a jurisdiction located in the United States of America and in the business of managing or advising clients.

“Voting Stocks” as applied to stock of any person, means shares, interests, participations or other equivalents in the equity interest (however designated) in such person having ordinary voting power for the election of the directors (or the equivalent) of such person, other than shares, interests, participations or other equivalents having such power only by reason of the occurrence of a contingency.

Except as provided above in connection with a Change of Control Triggering Event, the Series A Preferred Stock is not convertible into or exchangeable for any other securities or property.

For so long as the Series A Preferred Stock is outstanding, we will not exercise any option we have to convert any other series of our outstanding preferred stock to common stock, including the Issuer Optional Conversion, or any other security ranking junior to such preferred stock. As a result, and in accordance with ASC 480, we have presented both our 5.50% Preferred Stock and Series A Preferred Stock within temporary equity on our Consolidated Statement of Assets and Liabilities as of September 30, 2022.

Common Stock

Our common stockholders’ equity accounts as of September 30, 2022 and June 30, 2022 reflect cumulative shares issued, net of shares repurchased, as of those respective dates. Our common stock has been issued through public offerings, a registered direct offering, the exercise of over-allotment options on the part of the underwriters, our dividend reinvestment plan and in connection with the acquisition of certain controlled portfolio companies and in connection with our 5.50% Preferred Stock Holder Optional Conversion and Optional Redemption Following Death of a Holder. When our common stock is issued, the related offering expenses have been charged against paid-in capital in excess of par. All underwriting fees and offering expenses were borne by us.

We did not repurchase any shares of our common stock for the three months ended September 30, 2022 or September 30, 2021.

On June 10, 2022, at a special meeting of stockholders, our stockholders authorized us to sell shares of our common stock (during the next 12 months) at a price or prices below our net asset value per share at the time of sale in one or more offerings, subject to certain conditions as set forth in the proxy statement relating to the special meeting (including that the number of shares sold on any given date does not exceed 25% of its outstanding common stock immediately prior to such sale).
