Investment Objective

The investment objective of the Dimensional Ultrashort Fixed Income ETF (the "Ultrashort Fixed Income ETF" or "Portfolio") is to seek to maximize total returns. Total return is comprised of income and capital appreciation.

Fees and Expenses of the Portfolio

**This table describes the fees and expenses you may pay if you buy, hold or sell shares of the Portfolio. You may also incur usual and customary brokerage commissions when buying or selling shares of the Portfolio, which are not reflected in the table or Example that follows.**

---

| | |
|:---|:---|
| **Shareholder Fees (fees paid directly from your investment): None** |  |
| **Annual Fund Operating Expenses (expenses that you pay each <br>year as a percentage of the value of your investment)** |  |
| Management Fee | **0.12%** |
| Other Expenses | **0.02%** |
| Recovery of Previously Waived Fees<sup>1</sup> | **0.01%** |
| Total Annual Fund Operating Expenses | **0.15%** |

---

<sup>1</sup> Dimensional Fund Advisors LP (the "Advisor") has agreed to waive certain fees and in certain instances, assume certain expenses of the Portfolio. The Fee Waiver and/or Expense Assumption Agreement for the Portfolio will remain in effect through February 28, 2027, and may only be terminated by the Trust's Board of Trustees prior to that date. Under certain circumstances, the Advisor retains the right to seek reimbursement for any fees previously waived and/or expenses previously assumed up to thirty-six months after such fee waiver and/or expense assumption.

#### EXAMPLE
This Example is meant to help you compare the cost of investing in the Portfolio with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Portfolio for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Portfolio's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs whether you sell or hold your shares would be:

#### PORTFOLIO TURNOVER
A fund generally pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the Example, affect the Portfolio's performance. During the most recent fiscal year, the Portfolio's portfolio turnover rate was 33% of the average value of its investment portfolio.

Principal Investment Strategies

The Ultrashort Fixed Income ETF seeks to achieve its investment objective by generally investing in a universe of investment grade fixed income securities that typically mature in one year or less from the date of settlement. The Portfolio may, however, take a large position in securities maturing within two years from the date of settlement when higher yields are available. The Portfolio invests in U.S. government obligations, U.S. government agency obligations, dollar-denominated obligations of foreign issuers issued in the U.S., securities of domestic or foreign issuers denominated in U.S. dollars but not trading in the U.S., foreign government and agency obligations, bank obligations, including U.S. subsidiaries and branches of foreign banks, corporate obligations, commercial paper, repurchase agreements, money market funds and obligations of supranational organizations. As a non-fundamental policy, under normal circumstances, the Portfolio will invest at least 80% of its net assets in fixed income securities.

The Portfolio will maintain a weighted average effective maturity that will not exceed one year. The effective maturity adjusts the stated final maturity of a fixed income security for an actual or expected event such as a call, put, tender, mandatory early redemption, pre-refunding, coupon or interest rate reset, or other similar event. In making purchase decisions, if the expected term premium is greater for longer-term securities in the eligible maturity range, Dimensional Fund Advisors LP (the "Advisor") will focus investment in the longer-term area, otherwise, the Portfolio will focus investment in the shorter-term area of the eligible maturity range.

The fixed income securities in which the Portfolio invests are considered investment grade at the time of purchase (e.g., rated AAA to BBB- by S&P Global Ratings ("S&P") or Fitch Ratings Ltd. ("Fitch") or Aaa to Baa3 by Moody's Ratings ("Moody's"). The Portfolio principally invests in certificates of deposit, commercial paper, bankers' acceptances, notes and bonds. In addition, the Portfolio is authorized to invest more than 25% of its total assets in U.S. Treasury bonds, bills and notes, and obligations of federal agencies and instrumentalities.

The Portfolio may purchase or sell futures contracts and options on futures contracts, to hedge its interest rate exposure or for non-hedging purposes, such as a substitute for direct investment or to increase or decrease market exposure based on actual or expected cash inflows to or outflows from the Portfolio.

The Portfolio may lend its portfolio securities to generate additional income.

The Portfolio is an actively managed exchange-traded fund and does not seek to replicate the performance of a specific index and may have a higher degree of portfolio turnover than such index funds.

Principal Risks

Because the value of your investment in the Portfolio will fluctuate, there is the risk that you will lose money. An investment in the Portfolio is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The following is a description of principal risks of investing in the Portfolio.

***Market Risk:*** Even a long-term investment approach cannot guarantee a profit. Economic, market, environmental, political, and issuer-specific conditions and events will cause the value of securities, and a fund that owns them, to rise or fall.

***Foreign Securities and Currencies Risk:*** Foreign securities prices may decline or fluctuate because of: (a) economic or political actions of foreign governments, and/or (b) less regulated or liquid securities markets. Investors holding these securities may also be exposed to foreign currency risk (the possibility that foreign currency will fluctuate in value against the U.S. dollar or that a foreign government will convert, or be forced to convert, its currency to another currency, changing its value against the U.S. dollar).

Foreign issuers may not be subject to uniform accounting, auditing and financial reporting standards and there may be less reliable and publicly available financial and other information about such issuers, as compared to U.S. issuers. A fund may have greater difficulty voting proxies, exercising shareholder rights, securing dividends and/or interest and obtaining information regarding corporate actions on a timely basis, pursuing legal remedies, and obtaining judgments with respect to foreign investments in foreign courts than with respect to domestic issuers in U.S. courts.

***Foreign Government Debt Risk****:* The risk that: (a) the governmental entity that controls the repayment of government debt may not be willing or able to repay the principal and/or to pay the interest when it becomes due, due to factors such as political considerations, the relative size of the governmental entity's debt position in relation to the economy, cash flow problems, insufficient foreign currency reserves, the failure to put in place economic reforms required by the International Monetary Fund or other multilateral agencies, and/or other national economic factors; (b) governments may default on their debt securities, which may require holders of such securities to participate in debt rescheduling; and (c) there is no legal or bankruptcy process by which defaulted government debt may be collected in whole or in part.

***Income Risk:*** Income risk is the risk that falling interest rates will cause a fund's income to decline because, among other reasons, the proceeds from maturing short-term securities in its portfolio may be reinvested in lower-yielding securities.

***Interest Rate Risk:*** Fixed income securities are subject to interest rate risk because the prices of fixed income securities tend to move in the opposite direction of interest rates. When interest rates rise, fixed income security prices fall. During periods of very low or negative interest rates, a fund may be subject to a greater risk of rising interest rates. When interest rates fall, fixed income security prices rise. In general, fixed income securities with longer maturities are more sensitive to changes in interest rates.

***Credit Risk:*** Credit risk is the risk that the issuer of a security may be unable to make interest payments and/or repay principal when due. A downgrade to an issuer's credit rating or a perceived change in an issuer's financial strength may affect a security's value, and thus, impact the performance of a fund holding such securities. Government agency obligations have different levels of credit support and, therefore, different degrees of credit risk. Securities issued by agencies and instrumentalities of the U.S. Government that are supported by the full faith and credit of the United States, such as the Federal Housing Administration and Ginnie Mae, present little credit risk. Other securities issued by agencies and instrumentalities sponsored by the U.S. Government, that are supported only by the issuer's right to borrow from the U.S. Treasury, subject to certain limitations, and securities issued by agencies and instrumentalities sponsored by the U.S. Government that are sponsored by the credit of the issuing agencies, such as Freddie Mac and Fannie Mae, are subject to a greater degree of credit risk. U.S. government agency securities issued or guaranteed by the credit of the agency may still involve a risk of non-payment of principal and/or interest.

***Call Risk****:* Call risk is the risk that during periods of falling interest rates, an issuer will call or repay a higher-yielding fixed income security before its maturity date, forcing a fund to reinvest in fixed income securities with lower interest rates than the original obligations.

***Derivatives Risk:*** Derivatives are instruments, such as futures contracts, and options thereon, whose value is derived from that of other assets, rates or indices. Derivatives can be used for hedging (attempting to reduce risk by offsetting one investment position with another) or non-hedging purposes. Hedging with derivatives may increase expenses, and there is no guarantee that a hedging strategy will work. While hedging can reduce or eliminate losses, it can also reduce or eliminate gains or cause losses if the market moves in a manner different from that anticipated by a fund or if the cost of the derivative outweighs the benefit of the hedge. The use of derivatives for non-hedging purposes may be considered to carry more risk than other types of investments. When a fund uses derivatives, the fund will be directly exposed to the risks of those derivatives. Derivative instruments are subject to a number of risks including counterparty, settlement, liquidity, interest rate, market, credit and management risks, as well as difficulties with respect to valuation. Changes in the

<br> Dimensional Ultrashort Fixed Income ETF 5

------

value of a derivative may not correlate perfectly with the underlying asset, rate or index, and a fund could lose more than the principal amount invested.

***Liquidity Risk:*** Liquidity risk exists when particular portfolio investments are difficult to purchase or sell. To the extent that a fund holds illiquid investments, the fund's performance may be reduced due to an inability to sell the investments at opportune prices or times. Liquid portfolio investments may become illiquid or less liquid after purchase by a fund due to low trading volume, adverse investor perceptions, credit tightening and/or other market developments. Liquidity risk includes the risk that a fund will experience significant net redemptions at a time when it cannot find willing buyers for its portfolio securities or can only sell its portfolio securities at a material loss or at increased costs. Liquidity risk can be more pronounced in periods of market turmoil or in situations where ownership of shares of a fund are concentrated in one or a few investors. Investments that are illiquid or that trade in lower volumes may be more difficult to value.

***Securities Lending Risk:*** Securities lending involves the risk that the borrower may fail to return the securities in a timely manner or at all. As a result, a fund may lose money and there may be a delay in recovering the loaned securities. A fund could also lose money if it does not recover the securities and/or the value of the collateral falls, including the value of investments made with cash collateral. Securities lending also may have certain adverse tax consequences.

***Market Trading Risk:*** Active trading markets for a fund's shares may not be developed or maintained by market makers or authorized participants. Authorized participants are not obligated to make a market in a fund's shares or to submit purchase or redemption orders for creation units, which may widen bid-ask spreads. Trading in shares on an exchange may be halted in certain circumstances. There can be no assurance that the requirements of the listing exchange necessary to maintain the listing of a fund's shares will continue to be met. Additionally, in stressed market conditions, the market for a fund's shares may become less liquid in response to deteriorating liquidity in the markets for the fund's portfolio holdings, which may cause a significant variance in the market price of a fund's shares and their underlying value as well as an increase in a fund's shares' bid-ask spread.

***International Closed Market Trading Risk:*** To the extent that the underlying securities held by a fund trade on an exchange that is closed when the securities exchange on which a fund's shares list and trade is open, there may be market uncertainty about the stale security pricing (i.e., the last quote from its closed foreign market) resulting in premiums or discounts to NAV that may be greater than those experienced by other ETFs.

***Premium/Discount Risk:*** The net asset value ("NAV") of a fund's shares and the value of your investment may fluctuate. Disruptions to creations and redemptions or the market price of a fund's holdings, the existence of extreme market volatility or potential lack of an active trading market for shares may widen bid-ask spreads and result in shares trading at a significant premium or discount to NAV. If a shareholder

<br> 6 Dimensional Fund Advisors

------

purchases shares at a time when the market price is at a premium to the NAV or sells shares at a time when the market price is at a discount to the NAV, the shareholder may sustain losses.

***Operational Risk:*** Operational risks include human error, changes in personnel, system changes, faults in communication, and failures in systems, technology, or processes, and the use of artificial intelligence and machine learning ("AI"). Various operational events or circumstances are outside a fund's or its advisor's control, including instances at third parties. A fund and its advisor seek to reduce these operational risks through controls and procedures. However, measures that seek to reduce these operational risks through controls and procedures may not address every possible risk and may be inadequate to address these risks.

***Cyber Security Risk:*** A fund and its service providers' use of internet, technology and information systems may expose the fund to potential risks linked to cyber security breaches of those technological or information systems. Cyber security breaches, amongst other things, could allow an unauthorized party to gain access to proprietary information, customer data, or fund assets, or cause the fund and/or its service providers to suffer data corruption or lose operational functionality.

Performance

The bar chart and table immediately following illustrate the variability of the Portfolio's returns and are meant to provide some indication of the risks of investing in the Portfolio. The bar chart shows the changes in the Portfolio's performance from year to year. The table illustrates how annualized returns for certain periods, both before and after taxes, compare with those of a broad measure of market performance. The table also includes the performance of an additional index with a similar investment universe as the Portfolio. The Portfolio's past performance (before and after taxes) is not an indication of future results. Updated performance information for the Portfolio can be obtained by visiting https://www.dimensional.com/us-en/funds.

The after-tax returns presented in the table for the Portfolio are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor's tax situation and may differ from those shown in the table. In addition, the after-tax returns shown are not relevant to investors who hold shares of the Portfolio through tax-advantaged arrangements, such as 401(k) plans or individual retirement accounts.

Investment Advisor/Portfolio Management

Dimensional Fund Advisors LP serves as the investment advisor for the Portfolio. Dimensional Fund Advisors Ltd. and DFA Australia Limited serve as the sub-advisors for the Portfolio. The following individuals are responsible for leading the day-to-day management of the Portfolio:

• **Ryan C. Haselton**, Vice President and Senior Portfolio Manager of the Advisor, has been a portfolio manager of the Portfolio since inception (2023).

• **Joseph F. Kolerich**, Head of Fixed Income, Americas, member of the Investment Committee, Vice President, and Senior Portfolio Manager of the Advisor, has been a portfolio manager of the Portfolio since inception (2023).

• **David A. Plecha,** Global Head of Fixed Income Portfolio Management, member of the Investment Committee, Vice President, and Senior Portfolio Manager of the Advisor, has been a portfolio manager of the Portfolio since inception (2023).

Purchase and Sale of Fund Shares

The Portfolio issues (or redeems) shares at NAV only to certain financial institutions that have entered into agreements with the Portfolio's distributor in large aggregated blocks known as "Creation Units." A Creation Unit of the Portfolio consists of 50,000 shares. Creation Units are generally issued (or redeemed) in exchange for cash or in-kind for securities and a specified amount of cash that the Portfolio specifies each day at the NAV next determined after receipt of an order.

Individual Portfolio shares may only be purchased and sold on NYSE Arca, Inc., other national securities exchanges, electronic crossing networks and other alternative trading systems through your broker-dealer at market prices. An investor may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase shares (bid) and the lowest price a seller is willing to accept for shares (ask) when buying or selling shares in the secondary market (the "bid-ask spread"). Because Portfolio shares trade at market prices rather than at NAV, Portfolio shares may trade at a price less than (discount) or greater than (premium) the Portfolio's NAV. Recent information, including information on the Portfolio's NAV, market price, premiums and discounts, and bid-ask spreads, is available on the Portfolio's website at https://www.dimensional.com/us-en/funds.

Tax Information

The dividends and distributions you receive from the Portfolio are taxable and generally will be taxed as ordinary income, capital gains, or some combination of both, unless you are investing through a tax-advantaged arrangement, such as a 401(k) plan or an individual retirement account, in which case distributions may be taxed as ordinary income when withdrawn from the plan or account.

Payments to Financial Intermediaries

If you purchase the Portfolio through a broker-dealer or other financial intermediary (such as a bank), the Portfolio and its related companies may pay the intermediary for the sale of the Portfolio shares and/or related services. These payments may create a conflict of interest by influencing the financial intermediary to recommend the Portfolio over another investment. Ask your financial advisor or visit your financial intermediary's website for more information.
