Proxy Statement

An important message from CEO Salim Ramji

Dear fellow shareholder,

On behalf of the Board of Trustees, I’m pleased to announce that Vanguard Financials Index Fund and Vanguard Health Care Index Fund (each, a “Fund,” and collectively, the “Funds”) will hold a virtual Joint Special Meeting of Shareholders on October 21, 2025. All shareholders who own shares of either Fund as of the record date of August 26, 2025, have an opportunity to vote. I urge you to review the proxy materials carefully and then vote online, by phone, by mail, or by attending the virtual shareholder meeting.

The purpose of this Proxy Statement is to present a proposal for each Fund to approve changing its classification from “diversified” to “nondiversified” and the elimination of each Fund’s related fundamental investment restriction. The Board of Trustees considered relevant factors, including the potential impact of the proposal on each Fund and its risk profile, the recommendation from each Fund’s investment advisor, and the estimated costs associated with seeking shareholder approval of each proposal. The Board of Trustees believes that reclassifying each Fund as nondiversified is in the best interests of each Fund and its shareholders because it will allow each Fund’s portfolio managers to directly track each Fund’s benchmark index without incurring additional expenses, thus allowing for potentially better investment performance.

The Board of Trustees recommends that shareholders of each Fund vote “FOR” the proposal for their Fund.

Please read the proxy materials and cast your vote promptly. Your vote matters. Thank you for taking the time to participate in this important process.

Sincerely,

Salim Ramji

Chief Executive Officer [________]

Information about the Proposals and Voting

On what am I being asked to vote and how will it affect my Fund?

Shareholders of Vanguard Financials Index Fund and Vanguard Health Care Index Fund (each, a “Fund,” and collectively, the “Funds”) are being asked to approve changing each Fund’s classification from a diversified fund to a nondiversified fund, as defined under the Investment Company Act of 1940, as amended ( the “1940 Act”), and the elimination of each Fund’s related fundamental investment restriction. which provides that, with respect to 75% of its total assets, a Fund will not purchase securities of any issuer, if as a result, more than 5% of its total assets would be invested in that issuer’s securities or purchase more than 10% of the outstanding voting securities of a single issuer (other than U.S. government securities and securities of other investment companies).

Vanguard and the Board of Trustees of each Fund believe these changes will enable each Fund’s portfolio managers to more efficiently and effectively manage each Fund in pursuing its investment objective to track its respective benchmark index and potentially result in better investment performance. If shareholders approve the reclassification of each Fund as a nondiversified fund, each Fund’s fundamental investment restriction regarding the diversification of its investments will be eliminated. Each Fund’s investment objective, strategy, and other investment policies will remain unchanged. However, each Fund will be subject to the additional risk of being nondiversified as a nondiversified fund typically presents a heightened degree of investment risk due to its ability to make more concentrated investments.

Who gets to vote?

Any person who owned shares of a Fund as of the record date of August 26, 2025, even if that person sold those shares after the record date, gets to vote on the proposal for that Fund.

Why am I being asked to vote?

As a shareholder, it is your right to vote on certain matters concerning your funds. If many shareholders choose not to vote, a Fund might not receive enough votes to reach quorum and conduct its Joint Special Meeting of Shareholders on October 21, 2025 (the “Meeting”). If quorum cannot be reached for a Fund, the Fund will have to adjourn the Meeting and send additional communications to shareholders to try to get more votes - a process that would result in additional costs for the Fund and thus for you as a Fund shareholder.

How do I vote?

You can vote your shares using one of the following methods:

•Online, by visiting the website provided on your proxy card or email notification.

•By phone, by calling the toll-free phone number on your proxy card or on the website provided in the proxy materials.

•By mail, by signing and dating the enclosed proxy card.

•By attending the virtual Meeting, which is to be held on Tuesday, October 21, 2025, at 11:00a.m., Eastern Time.

You are urged to vote as soon as possible to ensure that your Fund receives enough votes to reach quorum, which is required to hold the Meeting.

You are encouraged to vote online or by phone using the voting control number that appears on your proxy card or email notification. Votes may also be submitted during the Meeting. In most instances, shareholders may vote up until voting closes at the Meeting. If your shares are held through a brokerage account, bank, or other holder of record (each, an “intermediary”), your intermediary may request that

voting instructions are received in advance of the Meeting and provide additional information related to voting. All shares represented by valid proxies received on a timely basis prior to the tallying of the votes at the Meeting, regardless of the way they were provided, will be voted. Please contact your intermediary for additional information related to voting.

How do I sign the proxy card if I am voting by mail?

You must sign your name exactly as it appears on the enclosed proxy card. Unless your account preferences provide alternative instructions, either owner of a joint account may sign the proxy card or form but the signature must match the name exactly as it appears on the proxy card or form.

Who is Broadridge Financial Solutions Inc.?

Broadridge Financial Solutions Inc. (“Broadridge”) is a third-party proxy vendor that has been engaged to solicit shareholders and collect and tabulate proxy votes.

If your shares are held through an intermediary, such as a brokerage account, bank, or other holder of record, you will need to request a legal proxy from the intermediary (“Legal Proxy”) to receive access to the Meeting, which serves as proof of your proxy power and reflects your holdings. The intermediary will then provide the shareholder with a control number. We note that obtaining a legal proxy may take several days. Requests for registration should be received no later than 5:00 p.m., Easten Time, on Monday, October 20, 2025. Once shareholders have obtained a new control number, they must visit www.viewproxy.com/vanguard/broadridgevsm/ and submit their name and newly issued control number in order to register to participate in and vote at the Meeting.

PART I

An Overview of the Proposals

Shareholders of Vanguard Financials Index Fund and Vanguard Health Care Index Fund are being asked to vote on the proposal for their Fund set forth below. Only shareholders of record as of August 26, 2025, are entitled to vote on the proposal for their Fund.

As discussed in detail below, Vanguard and the Board of Trustees of each Fund believe that the proposals, if approved by shareholders, will enable each Fund’s portfolio managers to more efficiently and effectively manage each Fund in pursuing its investment objective to track its respective benchmark index. Each Fund’s current diversification limits are constraining the Fund’s ability to invest in index constituents directly in the same proportion as their respective benchmark index, which have become increasingly concentrated in a small number of issuers and are currently nondiversified. This has resulted in the Funds using indirect means, such as derivative instruments, to gain exposure to index constituents in order to track their respective benchmark index. If the proposals are approved, the Funds would be able to invest directly in benchmark index constituents without these constraints. This would enable the Funds to more efficiently track their respective benchmark index and allow for potentially better investment performance.

PART II

Details on the Proposals

Each Fund is currently classified as “diversified” within the meaning of the 1940 Act. As a diversified fund, each Fund is limited in its ownership of securities of any single issuer (also referred to as a "holding"). The Board has recommended that shareholders approve reclassifying each Fund from "diversified" to "nondiversified," as defined under the 1940 Act, to allow the Funds’ portfolio managers to more effectively track each Fund’s benchmark index. Under the 1940 Act, a change to a Fund's diversification status from diversified to nondiversified requires shareholder approval.

Relatedly, if a fund is classified as diversified then it is required to adopt a fundamental investment restriction to invest in accordance with that classification. Accordingly, each Fund currently has a fundamental policy to invest as a diversified fund. If shareholders approve changing a Fund's status from diversified to nondiversified, then the Fund's related fundamental policy will be eliminated.

What's the difference between diversified funds and nondiversified funds?

Under the 1940 Act, a mutual fund or exchange-traded fund (“ETF”) is classified as diversified or nondiversified. This classification governs a fund’s ownership limitations of securities of issuers. Each Fund currently operates as a diversified fund and therefore must operate in compliance with the 1940 Act diversification requirements. “Diversified” under the 1940 Act means that, with respect to 75% of its total assets, a Fund will not invest more than 5% of its total assets in the securities of a single issuer or own more than 10% of the outstanding voting securities of a single issuer (other than U.S. government securities and securities of other investment companies). In other words, a diversified fund may not invest more than 5% of its assets in an issuer, if, in the aggregate, the investments equal to 5% or more in an issuer amount to more than 25% of the fund’s total assets.

A nondiversified fund is a fund that is not required to meet the 1940 Act diversification requirements described above. Therefore, diversified funds are subject to stricter percentage limits on the amount of assets that can be invested in any one issuer. Changing the Funds' status to nondiversified would allow the Funds to directly track their benchmark indexes, which are each currently concentrated in a fewer number of issuers.

How will changing the Funds' diversification status under the 1940 Act benefit the Funds?

As described in each Fund’s prospectus, each Fund employs an indexing investment approach designed to track the performance of its benchmark index. Vanguard Financials Index Fund seeks to track the performance of the MSCI US Investable Market Index (IMI)/Financials 25/50 and Vanguard Health Care Index Fund seeks to track the performance of the MSCI US Investable Market Index (IMI)/Health Care 25/50 (each, a “Benchmark Index,” and collectively, the “Benchmark Indexes”). Each Fund’s Benchmark Index has increasingly become concentrated in a smaller number of issuers and is currently nondiversified, causing each Fund’s classification as diversified to limit its ability to effectively track its Benchmark Index. To maintain compliance with 1940 Act diversification requirements, each Fund has sought exposure to certain securities in its Benchmark Index indirectly, including through the use of derivatives, in furtherance of its investment objective to track its Benchmark Index.

Reclassifying each Fund as nondiversified would enable the Funds to directly own the desired amount of Benchmark Index constituents and therefore track their Benchmark Indexes more efficiently, thus reducing the need to gain exposure to Benchmark Index constituents indirectly, including through

derivatives, which entails additional costs and risks to the Funds. This change will also better align the Funds to funds in their peer groups, many of which are classified as nondiversified.

The Board considered Vanguard's recommendation to change the status of each Fund to nondiversified under the 1940 Act and the elimination of each Fund’s related fundamental policy. The Board considered relevant factors, including the potential impact of the proposals on the Funds and their risk profiles, Vanguard’s recommendation and belief that the proposals would benefit Fund shareholders, and the estimated costs associated with seeking shareholder approval of the proposals. The Board believes reclassifying the Funds as nondiversified is in the best interests of the Funds and their shareholders because it will allow the Funds’ portfolio managers to more efficiently track the Funds’ Benchmark Indexes, thus allowing for potentially better investment performance.

Following consideration of these matters, the Board unanimously approved the proposed change to reclassify each Fund as nondiversified and the elimination of each Fund’s related fundamental policy. It is anticipated that, if each of the proposals are approved by shareholders, each Fund’s diversification status will change and each Fund’s related fundamental policy will be eliminated shortly after the Meeting.

What will be the impact to a Fund’s risk profile if the proposal is approved?

The proposals will give each Fund the ability to invest a greater percentage of its assets in the obligations or securities of a smaller number of issuers or any one issuer as compared to a diversified fund. However, shareholders should note that if the change to each Fund’s classification from “diversified” to “non- diversified” is approved, each Fund’s risk profile may increase. Specifically, because a “nondiversified” fund may invest a greater percentage of its assets in a smaller group of issuers or any one issuer as compared to a diversified fund, the investment return of a nondiversified fund typically is more dependent upon the performance of a smaller number of issuers or any one issuer than that of a diversified fund.

A nondiversified fund is therefore more susceptible to adverse developments affecting any single issuer held in its portfolio than a diversified fund.

Are there other diversification requirements that will still apply to each Fund if it becomes nondiversified under the 1940 Act?

Yes. Although each Fund would no longer be subject to the 1940 Act diversification requirements, if shareholders approve the proposal for a Fund, the Fund will continue to be subject to federal tax diversification restrictions of Subchapter M of the Internal Revenue Code of 1986, as amended (the "IRC"). The IRC contains diversification requirements for mutual funds. These diversification requirements are frequently referred to as the "tax diversification requirements." Funds must satisfy two diversification tests under the IRC. First, at least 50% of the value of the fund's total assets must consist of cash, cash items, government securities, securities of other regulated investment companies (e.g., mutual funds), and investments in other securities that, with respect to any one issuer, represent neither (i) more than 5% of the assets of the fund, nor (ii) more than 10% of the voting securities of the issuer. Second, no more than 25% of the value of the fund's assets may be invested in (i) the securities of any one issuer (other than government securities or the securities of other regulated investment companies), (ii) the securities (other than the securities of other regulated investment companies) of two or more issuers that the fund controls and are engaged in similar trades or businesses, or (iii) the securities of one or more qualified publicly traded partnerships.

What happens if shareholders of a Fund do not approve the proposal for that Fund?

PART III

More on Proxy Voting and the Shareholder Meeting

Votes Needed to Approve Each Proposal

Shareholders of each Fund will vote separately on the proposal for their respective Fund. For a proposal to pass for a Fund, it must be approved by the lesser of (1) 67% or more of the Fund's voting securities present at the Meeting—if the holders of more than 50% of the Fund's outstanding voting shares are in virtual attendance at the meeting or represented by proxy, or (2) more than 50% of the Fund's outstanding voting securities.

Proxy Solicitation Methods

The Funds will solicit shareholder proxies in a variety of ways. All shareholders who are entitled to vote will receive these proxy materials electronically or in paper, depending on the shareholder’s delivery preferences. Broadridge has been engaged to assist in the solicitation of proxies for the Meeting. In addition, Broadridge and employees, officers, or agents of the Funds, Vanguard, or its affiliates may solicit shareholder proxies in person, online, by phone, by mail, or by email.

Proxy Solicitation Costs

Each Fund will pay all costs of soliciting proxies from its shareholders, including costs relating to the printing, mailing, and tabulation of proxies. The Funds currently estimate Broadridge’s solicitation costs to be approximately $2.5 million - $3.5 million and each Fund will pay its proportionate share of the costs in accordance with a fixed formula based on the number of shareholders of each Fund.These costs are estimates based on currently available information and are subject to change. By voting immediately, you can help your Fund avoid the considerable expense of additional proxy solicitations.

Quorum

Quorum must be achieved for the Meeting to occur. This means that more than thirty-three and one-third percent (33 1/3%) of the total combined net asset value of a Fund's shares must be represented at the Meeting—either in virtual attendance at the Meeting or by proxy. All returned proxies count toward a quorum, regardless of how they are voted ("For," "Against," or "Abstain"). The Funds will count abstentions and broker non-votes toward establishing a quorum, but against the approval of the proposals. (A broker non-vote is a proxy received from a broker who holds fund shares on behalf of an investor, but who does not have discretionary power to vote the shares on the investor's behalf, indicating that the broker has not received instructions from the investor on the matter at issue.) Because the proposals may be considered non-routine, it is expected that broker-dealers, in the absence of specific authorization from their customers, will not have discretionary authority to vote any shares held beneficially by their customers and therefore there are unlikely to be any broker non-votes at the Meeting. Signed and dated proxy cards returned to Vanguard without a choice indicated as to a proposal shall be voted "For" the proposal. Approval of the proposals is discussed above in "Votes Needed to Approve Each Proposal."

Virtual Meeting

The Meeting will be held in a virtual format only. You are invited to attend the Meeting by visiting www.viewproxy.com/vanguard/broadridgevsm/ . You will be required to enter your name, your email address, and the control number found on the proxy card or email notification you received. If your shares are held through an intermediary, you will need to request a Legal Proxy from the intermediary to receive access to the Meeting. You must submit the Legal Proxy along with your name and email address to Broadridge. Shareholders may submit questions online prior to the Meeting at www.viewproxy.com/vanguard/broadridgevsm/ . Questions may be submitted in advance of the Meeting to Broadridge no later than 8:00a.m. Eastern Time on Monday, October 20, 2025. Shareholders will also have an opportunity to submit questions and comments during the Meeting via a questions pane. The questions pane will not be visible to other attendees and will be monitored for questions and comments

that relate to the proposals included in this Proxy Statement. The submission of questions and comments does not guarantee that any of them will be addressed during the Meeting.

Adjournment

The Meeting may be adjourned by a Fund’s Board, chief executive officer, or president, or chair of the Meeting, one or more times for any reason (without shareholder vote), including the failure of a quorum to be present at the Meeting. No shareholder vote is required for adjournment. The Meeting may be adjourned for one Fund regardless of whether action has been taken on the proposal with respect to the other Fund. No notice of adjournment of the Meeting to another time or place need be given to the shareholders if such time and place (including that the Meeting will be held by remote communication) are announced at the Meeting at which the adjournment is taken, or notice is given to persons present at the Meeting. Any adjourned Meeting may be held at such time and place, or virtually, as applicable, as determined by a Fund’s Board, chief executive officer, or president, or chair of the Meeting, in the Board’s or such person’s sole discretion. Any business that might have been transacted at the original Meeting may be transacted at any adjourned Meeting. If quorum is present with respect to a Fund, the chair of the Meeting may, but shall not be required to, cause a vote to be taken with respect to the proposal for such Fund, which vote can be certified as final and effective notwithstanding the adjournment of the Meeting with respect to the other Fund. The shareholders of record entitled to vote at such adjourned Meeting shall be the shareholder on the original record date, unless the Board establishes a new record date.

Postponement

Prior to the Meeting, a Fund’s Board, chief executive officer, or president, or chair of the Meeting, may postpone the Meeting one or more times for any reason by giving notice to each shareholder entitled to vote at the Meeting so postponed of the time and place at which such Meeting will be held. Notice shall be given not fewer than two days (or such other number of days as the Board shall determine in its sole discretion) before the date of such Meeting and otherwise in accordance with a Fund’s by-laws.

Revoking Your Proxy

Your last vote is the one that counts. Therefore, you can revoke a prior proxy simply by voting again- online, with your proxy card, or by phone. You can also revoke a prior proxy by writing to the Funds’ secretary at the following address: Tonya Robinson, The Vanguard Group, Inc., P.O. Box 876, Valley Forge, PA 19482, or by voting at the Meeting. You may revoke your proxy at any time until the announcement that voting has closed at the Meeting.

Shareholder Proposals

Any shareholder proposals to be included in a proxy statement for a Fund’s next shareholder meeting must be received by the Fund within a reasonable period before the Fund begins to print and mail its proxy statement for that meeting. Timely submission of a proposal does not guarantee that such proposal will be included in a proxy statement.
