**Investment Objective**

The Fund seeks to track the investment results of an index composed of the broad U.S. Treasury bond market.

**Fees and Expenses**

The following tables describe the fees and expenses you may pay if you buy, hold, and sell shares of the Fund. **You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the tables and example below.**

**Shareholder Fees**

(Fees paid directly from your investment)

 <br> <u> Transaction Fee on Purchases and Sales </u> <u> None\* </u> <br> Transaction Fee on Reinvested Dividends None\*

\*

None through Vanguard (Broker fees vary)

**Annual Fund Operating Expenses**

(Expenses that you pay each year as a percentage of the value of your investment)

---

| | |
|:---|:---|
| Management Fees | 0.00<br> %<br>|
| 12b-1 Distribution Fee |  |
| Other Expenses | 0.03<br> %<br>|
| Total Annual Fund Operating Expenses<sup>1</sup> <br>| 0.03<br> %<br>|

---

The expense information shown in the table reflects estimated amounts for the current fiscal year.

Example

The following example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. It illustrates the hypothetical expenses that you would incur over various periods if you were to invest $10,000 in the Fund's shares. This example assumes that the Fund provides a return of 5% each year and that total annual fund operating expenses remain as stated in the preceding table. You would incur these hypothetical expenses whether or not you were to sell your shares at the end of the given period. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

---

| | |
|:---|:---|
| 1 Year | 3 Years |
| $3 | $10 |

---

------

This example does not include the brokerage commissions that you may pay to buy and sell shares of the Fund.

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in more taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the previous expense example, reduce the Fund's performance. The Fund has no operating history and therefore has no portfolio turnover information.

**Principal Investment Strategies**

The Fund seeks to track the investment results of the Bloomberg U.S. Treasury Total Return Unhedged USD Index (the Index), which measures the performance of U.S. dollar denominated sovereign debt publicly issued by the U.S. government in its domestic market.

The Fund invests by sampling the Index, meaning that it holds a range of securities that, in the aggregate, approximates the full Index in terms of key risk factors and other characteristics. Under normal circumstances, the Fund will generally invest all, but at least 80%, of its net assets (plus any borrowings for investment purposes) in the securities comprising the Index and in securities that the advisor determines have economic characteristics that are substantially identical to the economic characteristics of the securities that comprise the Index. The Fund maintains a dollar-weighted average maturity consistent with that of the Index. As of May 31, 2025, the dollar-weighted average maturity of the Index was 7.6 years.

**Principal Risks**

An investment in the Fund could lose money over short or long periods of time. You should expect the Fund's share price and total return to fluctuate within a wide range. The Fund is subject to the following risks, which could affect the Fund's performance, and the level of risk may vary based on market conditions:

• *Interest rate risk*, which is the chance that bond prices overall will decline because of rising interest rates.

• *Income risk*, which is the chance that a Fund's income will decline because of falling interest rates. A fund's income declines when interest rates fall because the fund then must invest new cash flow and cash from maturing bonds in lower- yielding bonds. Income risk is generally high for short-term bond funds and

------

moderate for intermediate-term bond funds, so investors should expect the Fund's monthly income to fluctuate accordingly.

• *Income fluctuations*. The Fund's quarterly income distributions are likely to fluctuate considerably more than the income distributions of a typical bond fund. In fact, under certain conditions, the Fund may not have any income to distribute. Income fluctuations associated with changes in interest rates are expected to be low; however, income fluctuations associated with changes in inflation are expected to be high.

• *Indexing risks.* The Fund is subject to risks associated with index investing. Because the Fund generally seeks to track the performance of its target index regardless of how that index is performing, the Fund's performance may be lower than it would be if the Fund were actively managed. Additionally, because the Fund does not hold all of the securities included in its target index, it is subject to the risk that the representative sample of securities selected by the advisor will, in the aggregate, vary from the investment profile of its full target index. The performance of the Fund's investments, in the aggregate, may not match the investment performance of its target index. This risk, known as tracking error risk, may be heightened during times of increased market volatility or under other unusual market conditions. The Fund also could be negatively impacted by changes to the target index made by the index provider or by errors made by the index provider. Any gains, losses, or costs associated with or resulting from an error made by the index provider will generally be borne by the Fund and, as a result, the Fund's shareholders.

Because the Fund is an exchange-traded fund (ETF) and the Fund's shares are traded on an exchange, the Fund is subject to additional risks:

• The Fund's ETF Shares are listed for trading on NYSE Arca and are bought and sold on the secondary market at market prices. Although it is expected that the market price of an ETF Share typically will approximate its net asset value (NAV), there may be times when the market price and the NAV differ significantly. Thus, you may pay more or less than NAV when you buy ETF Shares on the secondary market, and you may receive more or less than NAV when you sell those shares.

• Although the Fund's ETF Shares are listed for trading on NYSE Arca, it is possible that an active trading market may not be maintained.

• Trading of the Fund's ETF Shares may be halted by the activation of individual or marketwide trading halts (which halt trading for a specific period of time when the price of a particular security or overall market prices decline by a specified percentage). Trading of the Fund's ETF Shares may also be halted if (1) the shares are delisted from NYSE Arca without first being listed on another

------

exchange or (2) NYSE Arca officials determine that such action is appropriate in the interest of a fair and orderly market or for the protection of investors.

**An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.**

**Annual Total Returns**

This is the Fund's initial prospectus, so it does not contain performance data.

**Investment Advisor**

The Vanguard Group, Inc. (Vanguard)

Portfolio Manager

Joshua C. Barrickman, CFA, Principal of Vanguard and co-head of Vanguard's Fixed Income Indexing Americas. He has managed the Fund since its inception in July 2025.

**Purchase and Sale of Fund Shares**

ETF Shares may only be bought and sold in the secondary market through a brokerage firm. The price you pay or receive for ETF Shares will be the prevailing market price, which may be more (premium) or less (discount) than the NAV of the shares. The brokerage firm may charge you a commission to execute the transaction. Unless imposed by your brokerage firm, there is no minimum dollar amount you must invest and no minimum number of shares you must buy. ETF Shares of the Fund cannot be directly purchased from or redeemed with the Fund, except by certain authorized broker-dealers. These broker-dealers may purchase and redeem ETF Shares only in large blocks (Creation Units), typically in exchange for baskets of securities.

An investor may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase ETF Shares (bid) and the lowest price a seller is willing to accept for ETF Shares (ask) when buying or selling shares in the secondary market (bid-ask spread). Recent information, including information on the Fund's NAV, market price, premiums and discounts, and bid-ask spreads, is available online at *vanguard.com.*

**Tax Information**

The Fund's distributions may be taxable as ordinary income or capital gains. If you are investing through a tax-advantaged account, such as an IRA or an employer-sponsored retirement or savings plan, special tax rules apply. You should consult your own tax advisor with respect to any particular U.S. or non-U.S. tax consequences of your investment in the Fund.

**Payments to Financial Intermediaries**

The Fund and its investment advisor do not pay financial intermediaries for sales of Fund shares.
