Your Fund’s Performance at a Glance

• For the 12 months ended October 31, 2023, Vanguard Explorer Fund returned –2.33% for Investor Shares and –2.24% for Admiral Shares. The fund held up better than its benchmark, the Russell 2500 Growth Index, which returned –4.80%.

• Early on, inflation continued to ease amid ongoing interest rate hikes by the Federal Reserve. Unexpected resilience in the labor market and consumer spending helped dial back expectations of a sustained recession, but the prospect of higher interest rates for longer and heightened geopolitical tensions weighed on market sentiment toward the close of the period.

• Growth stocks outperformed their value counterparts and large-capitalization stocks outpaced small- and mid-caps.

• Six of the fund’s 11 sectors contributed to performance. Health care, industrials, and energy produced the strongest results. Consumer discretionary and consumer staples were the biggest detractors.

Advisors’ Report

For the 12 months ended October 31, 2023, Vanguard Explorer Fund returned –2.33% for Investor Shares and –2.24% for Admiral Shares. It held up better than its benchmark, the Russell 2500 Growth Index, which returned –4.80%.

Your fund is managed by five independent advisors, a strategy that enhances its diversification by providing exposure to distinct yet complementary investment approaches. It’s not uncommon for different advisors to have different views about individual securities or the broader investment environment.

The table on page 6 lists the advisors, the amount and percentage of fund assets each manages, and brief descriptions of their investment strategies.

The advisors have provided the following assessment of the investment environment during the past 12 months and the notable successes and shortfalls in their portfolios. These comments were prepared on November 14, 2023.

Director and Equity Portfolio Manager

During the year ended October 31, 2023, small-capitalization stocks posted negative results, as measured by the Russell 2000 Index, and underperformed large-cap stocks, as measured by the Standard & Poor’s 500 Index.

Our stock selection in health care, communication services, and industrials contributed to relative returns, while selection in utilities and information technology hurt results. Our underweights to health care and energy and an overweight to industrials added to performance, while our underweight to information technology detracted.

Builders FirstSource, a manufacturer and supplier of building materials, was a top relative contributor during the period. Shares of Builders FirstSource ended the period higher, driven by better-than-expected results in the manufactured products and windows, doors, and millwork segments. Bumble, an online dating application operator, was the top relative detractor. Shares fell after the company struggled with competitive intensity/saturation concerns in the industry and recent management turnover.

We remain excited about the holdings in the portfolio and are confident that individual company fundamentals will be the key driver of returns over the long term, with the market ultimately rewarding those with high-quality management teams, competitive differentiation, and strong balance sheets.

Persistent inflation, higher interest rates, and economic uncertainty contributed to a complicated and challenging market environment. While economic data have generally been surprisingly strong, there were signs of stress in the system, initially in the banking industry. Toward the end of the period, the Federal Reserve seemed to pause on rate hikes, but market dynamics shifted long-term rates higher. Companies, consumers, and even the federal government are starting to feel the impact of the higher debt costs.

Our concerns about the impact of inflation and higher rates were largely justified. We have been and continue to be positioned for slower economic growth and more stress in the system. We eliminated our exposure to banks last year, and this year we have a conservative stance on consumer spending.

Higher interest rates and the uncertain and rapidly changing environment have caused a great deal of dispersion across the market—creating real winners and real losers. Our focus on quality growth companies has led to success across most of the portfolio. Technology stocks stood out even more, as we have been able to capitalize on some of the changes brought about by advancements in artificial intelligence.

We believe there is significant risk of a recession, but we worry more about the policy response to a recession. If the Fed or the administration intervenes too quickly, there is risk of another bout of inflation. We see continued opportunity for selective stock-picking with a bias

toward secular-growth companies with clean balance sheets.

At the beginning of the period, inflation eased off multidecade highs amid the Fed’s interest rate hikes. Unexpected resilience in labor markets and consumer spending helped lower expectations of a sustained recession in the U.S., but the prospect of higher rates for longer and heightened geopolitical tensions weighed on market sentiment toward the end of the period.

Although it’s important to understand how overall performance is affected by such macroeconomic factors, our approach to investing focuses on several key characteristics, including high quality—healthy balance sheets and steady cash-flow generation; effective management decisions—sound investment policies that favor internal over external funding; consistent earnings growth—ability to grow earnings year after year; strong market sentiment—market confirmation of our view; reasonable valuation—shares that are not overpriced; and defensive characteristics—evaluation of heavily shorted stocks that can signal concerns over future company prospects.

Using these six themes, we generate a daily composite stock ranking. We then monitor our portfolio based on that

3

ranking and adjust when appropriate to maximize expected returns while minimizing exposure to risks that our research indicates don’t improve returns.

After extensive research, we enhanced our stock-selection model in February with an artificial-intelligence-driven component applied to each of our six themes. This AI approach relies on a proprietary deep-neural net architecture developed in-house to preserve the fundamentals-driven approach we espouse, while making our selection process sensitive to changing economic and market conditions.

The AI forecasts are blended with our traditional scores to generate an ensemble of daily stock rankings. We then follow our standard approach of monitoring the portfolio based on those rankings and adjust when appropriate. In addition, to properly assess the decisions of the model, we developed a suite of AI interpretability tools that allow us to understand the drivers of the stock scores.

For the 12 months ended October 31, 2023, our defensive, management decisions, market sentiments, quality, and valuation models contributed to our relative performance, while our growth model slightly detracted. Our positions in eight of 11 industry sectors boosted relative performance. The strongest sector results were in industrials, health care, and energy. Our positions in financials, real estate, and consumer staples detracted.

At the stock level, top contributors included overweight positions in Axcelis Technologies, Jabil, and Manhattan Associates in information technology and e.l.f. Beauty in consumer staples, as well as an underweight to Novocure in health care. Overweights to Karyopharm Therapeutics and Nevro in health care and underweights to MarketAxess in financials as well as Penumbra and Prometheus Biosciences in health care detracted the most.

As 2022 ended, investor pessimism was high, given recession fears and uncertainty about inflation and the terminal interest rate. Throughout the first half of 2023, sentiment improved as inflation and corporate earnings data came in better than expected, giving investors more confidence in a “soft landing” for the economy. However, this optimism dissipated as the Fed’s persistent “higher-for-longer” narrative influenced expectations for a materially higher 10-year U.S. Treasury yield, which rose as high as 5% in October, putting pressure on growth equities.

Over the 12 months, the largest sector contributors were industrials and health

4

care, largely because of company-specific drivers. The weakest sector was consumer discretionary; portfolio holdings Etsy, Leslie’s, and National Vision were all affected by difficult pandemic comparisons and diminished consumer spending.

Top contributors to relative performance were Vertiv, which improved its supply chain and price/cost spread, while data center trends remained strong; XPO, which took market share and benefited from the promise of improving margins under a new CEO; and Horizon Therapeutics, which was acquired by Amgen.

Despite the uncertain trajectory of growth and rising interest rates, which have presented our companies with many challenges, we are confident in our management teams’ ability to navigate them.

Amid indications that the Fed’s aggressive rate hike campaign was effectively cooling inflation without upending the U.S. economy, equity markets performance was mixed during the 12-month period.

Both consumer and producer price inflation decelerated considerably during the period—to the point where central bank policymakers unanimously agreed to stand pat on their key lending rate late in the period. The pause capped a run of 11 straight hikes dating back to March 2022, although Fed Chair Jerome Powell said that more increases were possible.

Over the 12 months under review, the largest contributors to our portfolio were online car auction company ACV Auctions and footwear company Skechers USA. Top detractors included health care equipment company QuidelOrtho and application software firm Consensus Cloud Solutions.

Although consumer spending has been stable and resilient, we are beginning to see signs of incremental softness that could lead to a broader slowdown. Against this backdrop, we expect volatility to remain elevated as investors react to shifting dynamics in an uncertain environment. While cognizant of the risks in such challenging conditions, we remain poised to take advantage of any market weakness and contraction in multiples by adding to holdings and building positions in new names when valuations decline to attractive levels. We remain focused on companies that have resilient business models capable of executing well in a higher rate environment.

About Your Fund’s Expenses

As a shareholder of the fund, you incur ongoing costs, which include costs for portfolio management, administrative services, and shareholder reports (like this one), among others. Operating expenses, which are deducted from a fund’s gross income, directly reduce the investment return of the fund.

A fund’s expenses are expressed as a percentage of its average net assets. This figure is known as the expense ratio. The following examples are intended to help you understand the ongoing costs (in dollars) of investing in your fund and to compare these costs with those of other mutual funds. The examples are based on an investment of $1,000 made at the beginning of the period shown and held for the entire period.

The accompanying table illustrates your fund’s costs in two ways:

• Based on actual fund return. This section helps you to estimate the actual expenses that you paid over the period. The ”Ending Account Value“ shown is derived from the fund‘s actual return, and the third column shows the dollar amount that would have been paid by an investor who started with $1,000 in the fund. You may use the information here, together with the amount you invested, to estimate the expenses that you paid over the period.

To do so, simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number given for your fund under the heading ”Expenses Paid During Period.“

• Based on hypothetical 5% yearly return. This section is intended to help you compare your fund‘s costs with those of other mutual funds. It assumes that the fund had a yearly return of 5% before expenses, but that the expense ratio is unchanged. In this case—because the return used is not the fund’s actual return—the results do not apply to your investment. The example is useful in making comparisons because the Securities and Exchange Commission requires all mutual funds to calculate expenses based on a 5% return. You can assess your fund’s costs by comparing this hypothetical example with the hypothetical examples that appear in shareholder reports of other funds.

Note that the expenses shown in the table are meant to highlight and help you compare ongoing costs only and do not reflect transaction costs incurred by the fund for buying and selling securities. Further, the expenses do not include any purchase, redemption, or account service fees described in the fund prospectus. If such fees were applied to your account, your costs would be higher. Your fund does not carry a “sales load.”

The calculations assume no shares were bought or sold during the period. Your actual costs may have been higher or lower, depending on the amount of your investment and the timing of any purchases or redemptions.

You can find more information about the fund’s expenses, including annual expense ratios, in the Financial Statements section of this report. For additional information on operating expenses and other shareholder costs, please refer to your fund’s current prospectus.

Explorer Fund
Investor Shares	$1,000.00	$1,022.94	$2.29

The calculations are based on expenses incurred in the most recent six-month period. The fund’s annualized six-month expense ratios for that period are 0.45% for Investor Shares and 0.34% for Admiral Shares. The dollar amounts shown as “Expenses Paid” are equal to the annualized expense ratio multiplied by the average account value over the period, multiplied by the number of days in the most recent six-month period, then divided by the number of days in the most recent 12-month period (184/365).

Explorer Fund

Notes to Financial Statements

Vanguard Explorer Fund is registered under the Investment Company Act of 1940 as an open-end investment company, or mutual fund. The fund offers two classes of shares: Investor Shares and Admiral Shares. Each of the share classes has different eligibility and minimum purchase requirements, and is designed for different types of investors.

A. The following significant accounting policies conform to generally accepted accounting principles for U.S. investment companies. The fund consistently follows such policies in preparing its financial statements.

1. Security Valuation: Securities are valued as of the close of trading on the New York Stock Exchange (generally 4 p.m., Eastern time) on the valuation date. Equity securities are valued at the latest quoted sales prices or official closing prices taken from the primary market in which each security trades; such securities not traded on the valuation date are valued at the mean of the latest quoted bid and asked prices. Securities for which market quotations are not readily available, or whose values have been affected by events occurring before the fund’s pricing time but after the close of the securities’ primary markets, are valued by methods deemed by the valuation designee to represent fair value and subject to oversight by the board of trustees. These procedures include obtaining quotations from an independent pricing service, monitoring news to identify significant market- or security-specific events, and evaluating changes in the values of foreign market proxies (for example, ADRs, futures contracts, or exchange-traded funds), between the time the foreign markets close and the fund’s pricing time. When fair-value pricing is employed, the prices of securities used by a fund to calculate its net asset value may differ from quoted or published prices for the same securities. Investments in Vanguard Market Liquidity Fund are valued at that fund's net asset value. Other temporary cash investments are valued using the latest bid prices or using valuations based on a matrix system (which considers such factors as security prices, yields, maturities, and ratings), both as furnished by independent pricing services.

2. Foreign Currency: Securities and other assets and liabilities denominated in foreign currencies are translated into U.S. dollars using exchange rates obtained from an independent third party as of the fund’s pricing time on the valuation date. Realized gains (losses) and unrealized appreciation (depreciation) on investment securities include the effects of changes in exchange rates since the securities were purchased, combined with the effects of changes in security prices. Fluctuations in the value of other assets and liabilities resulting from changes in exchange rates are recorded as unrealized foreign currency gains (losses) until the assets or liabilities are settled in cash, at which time they are recorded as realized foreign currency gains (losses).

3. Repurchase Agreements: The fund enters into repurchase agreements with institutional counterparties. Securities pledged as collateral to the fund under repurchase agreements are held by a custodian bank until the agreements mature, and in the absence of a default, such collateral cannot be repledged, resold, or rehypothecated. Each agreement requires that the market value of the collateral be sufficient to cover payments of interest and principal. The fund further mitigates its counterparty risk by entering into repurchase agreements only with a diverse group of prequalified counterparties, monitoring their financial strength, and entering into master repurchase agreements with its counterparties. The master repurchase agreements provide that, in the event of a counterparty's default (including bankruptcy), the fund may terminate any repurchase agreements with that counterparty, determine the net amount owed, and sell or retain the collateral up to the net amount owed to the fund. Such action may be subject to legal proceedings, which may delay or limit the disposition of collateral.

4. Futures Contracts: The fund uses index futures contracts to a limited extent, with the objective of maintaining full exposure to the stock market while maintaining liquidity. The fund may purchase or sell futures contracts to achieve a desired level of investment, whether to accommodate portfolio turnover or cash flows from capital share transactions. The primary risks associated with the use of futures contracts are imperfect correlation between changes in market values of stocks held by the fund and the prices of futures contracts, and the possibility of an illiquid market. Counterparty risk involving futures is mitigated because a regulated clearinghouse is the counterparty instead of the clearing broker. To further mitigate counterparty risk, the fund trades futures contracts on an exchange, monitors the financial strength of its clearing brokers and clearinghouse, and has entered into clearing agreements with its clearing brokers. The clearinghouse imposes initial margin requirements to secure the fund’s performance and requires daily settlement of variation margin representing changes in the market value of each contract. Any securities pledged as initial margin for open contracts are noted in the Schedule of Investments.

Futures contracts are valued at their quoted daily settlement prices. The notional amounts of the contracts are not recorded in the Statement of Assets and Liabilities. Fluctuations in the value of the contracts are recorded in the Statement of Assets and Liabilities as an asset (liability) and in the Statement of Operations as unrealized appreciation (depreciation) until the contracts are closed, when they are recorded as realized gains (losses) on futures contracts.

During the year ended October 31, 2023, the fund’s average investments in long and short futures contracts represented 2% and 0% of net assets, respectively, based on the average of the notional amounts at each quarter-end during the period.

5. Federal Income Taxes: The fund intends to continue to qualify as a regulated investment company and distribute virtually all of its taxable income. The fund’s tax returns are open to examination by the relevant tax authorities until expiration of the applicable statute of limitations, which is generally three years after the filing of the tax return. Management has analyzed the fund’s tax positions taken for all open federal and state income tax years, and has concluded that no provision for income tax is required in the fund’s financial statements.

6. Distributions: Distributions to shareholders are recorded on the ex-dividend date. Distributions are determined on a tax basis at the fiscal year-end and may differ from net investment income and realized capital gains for financial reporting purposes.

7. Securities Lending: To earn additional income, the fund lends its securities to qualified institutional borrowers. Security loans are subject to termination by the fund at any time, and are required to be secured at all times by collateral in an amount at least equal to the market value of securities loaned. Daily market fluctuations could cause the value of loaned securities to be more or less than the value of the collateral received. When this occurs, the collateral is adjusted and settled before the opening of the market on the next business day. The fund further mitigates its counterparty risk by entering into securities lending transactions only with a diverse group of prequalified counterparties, monitoring their financial strength, and entering into master securities lending agreements with its counterparties. The master securities lending agreements provide that, in the event of a counterparty’s default (including bankruptcy), the fund may terminate any loans with that borrower, determine the net amount owed, and sell or retain the collateral up to the net amount owed to the fund; however, such actions may be subject to legal proceedings. While collateral mitigates counterparty risk, in the event of a default, the fund may experience delays and costs in recovering the securities loaned. The fund invests cash collateral received in Vanguard Market Liquidity Fund, and records a liability in the Statement of Assets and Liabilities

for the return of the collateral, during the period the securities are on loan. Collateral investments in Vanguard Market Liquidity Fund are subject to market appreciation or depreciation. Securities lending income represents fees charged to borrowers plus income earned on invested cash collateral, less expenses associated with the loan. During the term of the loan, the fund is entitled to all distributions made on or in respect of the loaned securities.

8. Credit Facilities and Interfund Lending Program: The fund and certain other funds managed by The Vanguard Group ("Vanguard") participate in a $4.3 billion committed credit facility provided by a syndicate of lenders pursuant to a credit agreement and an uncommitted credit facility provided by Vanguard. Both facilities may be renewed annually. Each fund is individually liable for its borrowings, if any, under the credit facilities. Borrowings may be utilized for temporary or emergency purposes and are subject to the fund’s regulatory and contractual borrowing restrictions. With respect to the committed credit facility, the participating funds are charged administrative fees and an annual commitment fee of 0.10% of the undrawn committed amount of the facility, which are allocated to the funds based on a method approved by the fund’s board of trustees and included in Management and Administrative expenses on the fund’s Statement of Operations. Any borrowings under either facility bear interest at an agreed-upon spread plus the higher of the federal funds effective rate, the overnight bank funding rate, or the Daily Simple Secured Overnight Financing Rate inclusive of an additional agreed-upon spread. However, borrowings under the uncommitted credit facility may bear interest based upon an alternate rate agreed to by the fund and Vanguard.

In accordance with an exemptive order (the “Order”) from the SEC, the fund may participate in a joint lending and borrowing program that allows registered open-end Vanguard funds to borrow money from and lend money to each other for temporary or emergency purposes (the “Interfund Lending Program”), subject to compliance with the terms and conditions of the Order, and to the extent permitted by the fund’s investment objective and investment policies. Interfund loans and borrowings normally extend overnight but can have a maximum duration of seven days. Loans may be called on one business day’s notice. The interest rate to be charged is governed by the conditions of the Order and internal procedures adopted by the board of trustees. The board of trustees is responsible for overseeing the Interfund Lending Program. 

For the year ended October 31, 2023, the fund did not utilize the credit facilities or the Interfund Lending Program.

9. Other: Dividend income is recorded on the ex-dividend date. Non-cash dividends included in income, if any, are recorded at the fair value of the securities received. Interest income includes income distributions received from Vanguard Market Liquidity Fund and is accrued daily. Premiums and discounts on debt securities are amortized and accreted, respectively, to interest income over the lives of the respective securities, except for premiums on certain callable debt securities that are amortized to the earliest call date. Security transactions are accounted for on the date securities are bought or sold. Costs used to determine realized gains (losses) on the sale of investment securities are those of the specific securities sold.

Each class of shares has equal rights as to assets and earnings, except that each class separately bears certain class-specific expenses related to maintenance of shareholder accounts (included in Management and Administrative expenses) and shareholder reporting. Marketing and distribution expenses are allocated to each class of shares based on a method approved by the board of trustees. Income, other non-class-specific expenses, and gains and losses on investments are allocated to each class of shares based on its relative net assets.

B. The investment advisory firms Wellington Management Company llp, Stephens Investment Management Group, LLC, ClearBridge Investments, LLC, and ArrowMark Colorado Holdings, LLC, each provide investment advisory services to a portion of the fund for a fee calculated at an annual percentage rate of average net assets managed by the advisor. The basic fees of Wellington Management Company llp and ClearBridge Investments, LLC, are subject to quarterly adjustments based on performance relative to the Russell 2500 Growth Index for the preceding three years. The basic fees of Stephens Investment Management Group, LLC, and ArrowMark Colorado Holdings, LLC, are subject to quarterly adjustments based on performance relative to the Russell 2500 Growth Index for the preceding five years.

Vanguard provides investment advisory services to a portion of the fund as described below; the fund paid Vanguard advisory fees of $847,000 for the year ended October 31, 2023.

For the year ended October 31, 2023, the aggregate investment advisory fee paid to all advisors represented an effective annual basic rate of 0.17% of the fund’s average net assets, before a net increase of $8,107,000 (0.04%) based on performance.

C. In accordance with the terms of a Funds' Service Agreement (the “FSA”) between Vanguard and the fund, Vanguard furnishes to the fund investment advisory, corporate management, administrative, marketing, and distribution services at Vanguard’s cost of operations (as defined by the FSA). These costs of operations are allocated to the fund based on methods and guidelines approved by the board of trustees and are generally settled twice a month.

Upon the request of Vanguard, the fund may invest up to 0.40% of its net assets as capital in Vanguard. At October 31, 2023, the fund had contributed to Vanguard capital in the amount of $671,000, representing less than 0.01% of the fund’s net assets and 0.27% of Vanguard’s capital received pursuant to the FSA. The fund’s trustees and officers are also directors and employees, respectively, of Vanguard.

D.

The fund has asked its investment advisors to direct certain security trades, subject to obtaining the best price and execution, to brokers who have agreed to rebate to the fund part of the commissions generated. Such rebates are used solely to reduce the fund’s management and administrative expenses. For the year ended October 31, 2023, these arrangements reduced the fund’s expenses by $33,000 (an annual rate of less than 0.01% of average net assets).

E.

Various inputs may be used to determine the value of the fund’s investments and derivatives. These inputs are summarized in three broad levels for financial statement purposes. The inputs or methodologies used to value securities are not necessarily an indication of the risk associated with investing in those securities.

Level 1—Quoted prices in active markets for identical securities.

Level 2—Other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.).

Level 3—Significant unobservable inputs (including the fund’s own assumptions used to determine the fair value of investments). Any investments and derivatives valued with significant unobservable inputs are noted on the Schedule of Investments.

29

Explorer Fund

The following table summarizes the market value of the fund’s investments and derivatives as of October 31, 2023, based on the inputs used to value them:

1 Includes cumulative appreciation (depreciation) on futures contracts and centrally cleared swaps, if any, as reported in the Schedule of Investments. Only current day’s variation margin is reported within the Statement of Assets and Liabilities.

F. Permanent differences between book-basis and tax-basis components of net assets are reclassified among capital accounts in the financial statements to reflect their tax character. These reclassifications have no effect on net assets or net asset value per share. As of period end, permanent differences primarily attributable to the accounting for applicable distributions in connection with fund share redemptions were reclassified between the following accounts:

	Amount ($000)
Paid-in Capital	719
Total Distributable Earnings (Loss)	(719)

Temporary differences between book-basis and tax-basis components of total distributable earnings (loss) arise when certain items of income, gain, or loss are recognized in different periods for financial statement and tax purposes; these differences will reverse at some time in the future. The differences are primarily related to the deferral of losses from wash sales; and the recognition of unrealized gains or losses from certain derivative contracts. As of period end, the tax-basis components of total distributable earnings (loss) are detailed in the table as follows:

	Amount ($000)
Undistributed Ordinary Income	115,987
Undistributed Long-Term Gains	37,647
Net Unrealized Gains (Losses)	855,808
Capital Loss Carryforwards	—
Qualified Late-Year Losses	—
Other Temporary Differences	—
Total	1,009,442

G. During the year ended October 31, 2023, the fund purchased $7,489,874,000 of investment securities and sold $7,894,792,000 of investment securities, other than temporary cash investments.

The fund purchased securities from and sold securities to other funds or accounts managed by its investment advisors or their affiliates, in accordance with procedures adopted by the board of trustees in compliance with Rule 17a-7 of the Investment Company Act of 1940. For the year ended October 31, 2023, such purchases were $5,020,000 and sales were $25,722,000, resulting in net realized gain of $124,000; these amounts, other than temporary cash investments, are included in the purchases and sales of investment securities noted above.

I. Certain of the fund’s investments are in companies that are considered to be affiliated companies of the fund because the fund owns more than 5% of the outstanding voting securities of the company or the issuer is another member of The Vanguard Group. Transactions during the period in securities of these companies were as follows:

1	Not applicable—at October 31, 2022, the issuer was not an affiliated company of the fund.
2	Not applicable—purchases and sales are for temporary cash investment purposes.
3	Not applicable—at October 31, 2023, the security was still held, but the issuer was no longer an affiliated company of the fund.

J. Significant market disruptions, such as those caused by pandemics (e.g., COVID-19 pandemic), natural or environmental disasters, war (e.g., Russia’s invasion of Ukraine), acts of terrorism, or other events, can adversely affect local and global markets and normal market operations. Any such disruptions could have an adverse impact on the value of the fund’s investments and fund performance.

To the extent the fund’s investment portfolio reflects concentration in a particular market, industry, sector, country or asset class, the fund may be adversely affected by the performance of these concentrations and may be subject to increased price volatility and other risks.

The use of derivatives may expose the fund to various risks. Derivatives can be highly volatile, and any initial investment is generally small relative to the notional amount so that transactions may be leveraged in terms of market exposure. A relatively small market movement may have a potentially larger impact on derivatives than on standard securities. Leveraged derivatives positions can, therefore, increase volatility. Additional information regarding the fund’s use of derivative(s) and the specific risks associated is described under significant accounting policies.

We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of Vanguard Explorer Fund (the "Fund") as of October 31, 2023, the related statement of operationsfor the year ended October 31, 2023, the statement of changes in net assets for each of the two years in the period ended October 31, 2023, including the related notes,and the financial highlights for each of the five years in the period ended October 31, 2023 (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Fund as of October 31, 2023, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period ended October 31, 2023 and the financial highlights for each of the five years in the period ended October 31, 2023 in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements are the responsibility of the Fund’s management. Our responsibility is to express an opinion on the Fund’s 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 Fund 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 October 31, 2023 by correspondence with the custodian, transfer agent and brokers; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

The People Who Govern Your Fund

The trustees of your mutual fund are there to see that the fund is operated and managed in your best interests since, as a shareholder, you are a part owner of the fund. Your fund’s trustees also serve on the board of directors of The Vanguard Group, Inc., which is owned by the Vanguard funds and provides services to them. 

A majority of Vanguard’s board members are independent, meaning that they have no affiliation with Vanguard or the funds they oversee, apart from the sizable personal investments they have made as private individuals. The independent board members have distinguished backgrounds in business, academia, and public service. Each of the trustees and executive officers oversees 205 Vanguard funds.

Information for each trustee and executive officer of the fund appears below. That information, as well as the Vanguard fund count, is as of the date on the cover of this fund report. The mailing address of the trustees and officers is P.O. Box 876, Valley Forge, PA 19482. More information about the trustees is in the Statement of Additional Information, which can be obtained, without charge, by contacting Vanguard at 800-662-7447, or online at vanguard.com.
