The investment objective of the Dimensional Core Fixed Income ETF (the “Core Fixed Income ETF” or “Portfolio”) is to seek to maximize total returns from the universe of eligible investments. Total return is comprised of income and capital appreciation.

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.

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. The costs for the Portfolio reflect the net expenses of the Portfolio that result from the contractual expense waiver in the first year only. Although your actual costs may be higher or lower, based on these assumptions your costs whether you redeem or hold your shares would be:

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 39% of the average value of its investment portfolio.

The Core Fixed Income ETF will seek to achieve its investment objective through exposure to a broad portfolio of U.S. and foreign investment grade fixed income securities. The Portfolio may invest in obligations issued or guaranteed by the U.S. and foreign governments, their agencies and instrumentalities, including mortgage-backed securities, corporate debt obligations, bank obligations, commercial paper, repurchase agreements, money market funds, securities of domestic or foreign issuers denominated in U.S. dollars but not trading in the United States, and obligations of supranational organizations. The Portfolio may purchase or sell mortgage-backed securities on a delayed delivery or forward commitment basis through the “to-be-announced” (TBA) market. As a non-fundamental policy, under normal circumstances, at least 80% of the Portfolio’s net assets will be invested in fixed income securities considered to be investment grade quality.

The Portfolio will be managed with a view to capturing expected credit premiums and expected term premiums. The term “expected credit premium” means the expected incremental return on investment for holding obligations considered to have greater credit risk than direct obligations of the U.S. Treasury, and “expected term premium” means the expected relative return on investment for holding securities having longer-term maturities as compared to shorter-term maturities. In managing the Portfolio, the Advisor will increase or decrease investment exposure to intermediate-term securities depending on the expected term premium and also increase or decrease investment exposure to non-government securities depending on the expected credit premium.

The Portfolio may invest in fixed income securities 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 Investor’s Service, Inc. (“Moody’s”)). The Portfolio may invest with an emphasis on debt securities rated A+ to BBB- by S&P or Fitch or A1 to Baa3 by Moody’s. The Portfolio will increase or decrease investment exposure to lower-rated investment grade securities (i.e., those rated A+ to BBB- by S&P or Fitch or A1 to Baa3 by Moody’s) depending on the expected credit premium. 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 primarily invests in securities that mature within twenty years from the date of settlement, but may, as in the case of mortgage-backed securities, invest in securities with longer maturities. Under normal circumstances, the Portfolio will generally maintain a weighted average duration of no more than one quarter year greater than, and no less than one year below, the weighted average duration of the Bloomberg U.S. Aggregate Bond Index, which was approximately 6.24 years as of December 31, 2023. From time to time, the Portfolio may deviate from this duration range when the Advisor determines it to be appropriate under the circumstances. Duration is a measure of the sensitivity of a security’s price to changes in interest rates. The longer a security’s duration, the more sensitive it will be to changes in interest rates.

The Portfolio’s investments may include securities denominated in foreign currencies. The Portfolio intends to hedge foreign currency exposure to attempt to protect against uncertainty in the level of future foreign currency rates. The Portfolio may enter into foreign currency forward contracts to hedge against fluctuations in currency exchange rates or to transfer balances from one currency to another. The Portfolio also may enter into credit default swaps on issuers or indices to buy or sell credit protection to hedge its credit exposure; gain market or issuer exposure without owning the underlying securities; or increase the Portfolio’s total return. The Portfolio may purchase or sell futures contracts and options on futures contracts, to hedge its currency exposure or 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.

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

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.

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.

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.

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). The Portfolio hedges foreign currency risk.

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.

Mortgage-Backed Securities Risk: Mortgage-backed securities represent interests in “pools” of mortgages and often involve risks that are different from or potentially more significant than risks associated with other types of debt instruments. Mortgage securities differ from typical debt securities in that principal is not paid back at maturity, but rather periodically over the life of the security. A fund may receive unscheduled payments of principal due to voluntary prepayments, refinancings or foreclosures on the underlying mortgage loans. When interest rates decline, borrowers may pay off their mortgages sooner than expected. This can reduce the returns of a fund because it may have to reinvest that money at the lower prevailing interest rates. As a result, mortgage securities may be less effective than some other types of debt securities as a means of securing long-term interest rates and may have less potential for capital appreciation during periods of falling interest rates. Conversely, in a period of rising interest rates, a fund may exhibit additional volatility since rising interest rates tend to extend the duration of fixed rate mortgage-related securities, making them more sensitive to changes in interest rates. As interest rates rise mortgage

borrowers are less likely to exercise prepayment options, which may reduce the value of these securities and potentially cause a fund to lose money. This is known as extension risk.

Derivatives Risk: Derivatives are instruments, such as swaps, futures contracts, and options thereon, and foreign currency forward contracts, 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. In regard to currency hedging, it is generally not possible to precisely match the foreign currency exposure of such foreign currency forward contracts to the value of the securities involved due to fluctuations in the market values of such securities and cash flows into and out of a fund between the date a foreign currency forward contract is entered into and the date it expires. 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 the risk of improper valuation. Changes in the 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. Additional risks are associated with the use of swaps including counterparty and credit risk (the risk that the other party to a swap agreement will not fulfill its contractual obligations, whether because of bankruptcy or other default) and liquidity risk (the possible lack of a secondary market for the swap agreement). Credit risk increases when a fund is the seller of swaps and counterparty risk increases when the fund is a buyer of swaps. In addition, where a fund is the seller of swaps, it may be required to liquidate portfolio securities at inopportune times in order to meet payment obligations. Swaps may be illiquid or difficult to value.

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 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.

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 will continue to be met.

Premium/Discount Risk: The net asset value (“NAV”) of a fund 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 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.

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.

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.

Operational Risk: Operational risks include human error, changes in personnel, system changes, faults in communication, and failures in systems, technology, or processes. 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.

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 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.

The investment objective of the Dimensional Short-Duration Fixed Income ETF (the “Short-Duration Fixed Income ETF” or “Portfolio”) is to maximize total returns from the universe of fixed income securities in which the Portfolio invests. Total return is comprised of income and capital appreciation.

The Short-Duration Fixed Income ETF will seek to achieve its investment objective through exposure to a broad portfolio of U.S. and foreign corporate debt securities with an investment grade rating. In addition, the Portfolio may invest in obligations issued or guaranteed by the U.S. and foreign governments, their agencies and instrumentalities, including mortgage-backed securities, bank obligations, commercial paper, repurchase agreements, money market funds, corporate debt obligations having investment grade ratings, securities of domestic or foreign issuers denominated in U.S. dollars but not trading in the United States, and obligations of supranational organizations. As a non-fundamental policy, under normal circumstances, at least 80% of the Portfolio’s net assets will be invested in fixed income securities considered to be investment grade quality.

The Portfolio will increase or decrease investment exposure to lower-rated investment grade securities (i.e., those rated A+ to BBB- by S&P or Fitch or A1 to Baa3 by Moody’s) depending on the expected credit premium. The Advisor expects that the Portfolio will primarily invest in the obligations of issuers that are in developed countries.

The Portfolio primarily invests in securities that mature within five years from the date of settlement. Under normal circumstances, the Portfolio will generally maintain a weighted average duration of no more than one half year greater than, and no less than one year below, the weighted average duration of the ICE BofA 1-5 Year US Corporate & Government Index, which was approximately 2.56 years as of December 31, 2023. In making these purchase decisions, if the expected term premium is greater for longer-term securities in the eligible maturity range, the Advisor will focus on investment in the longer-term area, otherwise, the Portfolio will focus its investment in the shorter-term area of the eligible maturity range. Duration is a measure of the sensitivity of a security’s price to changes in interest rates. The longer a security’s duration, the more sensitive it will be to changes in interest rates.

The investment objective of the Dimensional Inflation-Protected Securities ETF (the “Inflation-Protected ETF” or “Portfolio”) is to provide inflation protection and earn current income consistent with inflation-protected securities.

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.

This Example is meant to help you compare the cost of investing in the Portfolio with the cost of investing in other funds.

During the most recent fiscal year, the Portfolio's portfolio turnover rate was 9% of the average value of its investment portfolio.

The Inflation-Protected ETF will seek to achieve its investment objective by investing in a universe of inflation-protected securities that are structured to provide returns linked to the rate of inflation over the long-term. The

Portfolio ordinarily invests in inflation-protected securities issued by the U.S. Government and its agencies and instrumentalities and the credit quality of such inflation-protected securities will be that of such applicable U.S. Government, agency or instrumentality issuer.

As a non-fundamental policy, under normal circumstances, at least 80% of the Portfolio’s net assets will be invested in inflation-protected securities. Inflation-protected securities (also known as inflation-indexed securities) are securities whose principal and/or interest payments are adjusted for inflation, unlike conventional debt securities that make fixed principal and interest payments. Inflation-protected securities include Treasury Inflation-Protected Securities (“TIPS”), which are securities issued by the U.S. Treasury. The principal value of TIPS is adjusted for inflation (payable at maturity) and the semi-annual interest payments by TIPS equal a fixed percentage of the inflation-adjusted principal amount. These inflation adjustments are based upon the Consumer Price Index for Urban Consumers (CPI-U). The original principal value of TIPS is guaranteed. At maturity, TIPS are redeemed at the greater of their inflation-adjusted principal or par amount at original issue. Other types of inflation-protected securities may use other methods to adjust for inflation and other measures of inflation. In addition, inflation-protected securities issued by entities other than the U.S. Treasury may not provide a guarantee of principal value at maturity.

Generally, the Portfolio will purchase inflation-protected securities with maturities between five and twenty years from the date of settlement, although at times, the Portfolio may purchase securities outside of this range. Under normal circumstances, when determining its duration, the Portfolio will consider an average duration similar to the Bloomberg U.S. TIPS Index, which was approximately 6.57 years as of December 31, 2023. Duration is a measure of the sensitivity of a security’s price to changes in interest rates. The longer a security’s duration, the more sensitive it will be to changes in interest rates.

The Portfolio is authorized to invest more than 25% of its total assets in U.S. Treasury bonds, bills and notes and obligations of U.S. government agencies and instrumentalities. The Portfolio may also invest in money market funds. The Portfolio will not shift the maturity of its investments in anticipation of interest rate movements.

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.

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

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.

Inflation-Protected Securities Tax Risk: Any increase in the principal amount of an inflation-protected security may be included for tax purposes in a fund’s gross income, even though no cash attributable to such gross income has been received by a fund. In such event, a fund may be required to make annual gross distributions to shareholders that exceed the cash it has otherwise received. In order to pay such distributions, a fund may be required to raise cash by selling its investments. The sale of such investments could result in capital gains to a fund and additional capital gain

distributions to shareholders. In addition, adjustments during the taxable year for deflation to an inflation-indexed bond held by a fund may cause amounts previously distributed to shareholders in the taxable year as income to be characterized as a return of capital, which could increase or decrease a fund’s ordinary income distributions to shareholders, and may cause some of a fund’s distributed income to be classified as a return of capital.

Inflation-Protected Securities Interest Rate Risk: Inflation-protected securities may react differently from other fixed income securities to changes in interest rates. Because interest rates on inflation-protected securities are adjusted for inflation, the values of these securities are not materially affected by inflation expectations. Therefore, the value of inflation-protected securities are anticipated to change in response to changes in “real” interest rates, which represent nominal (stated) interest rates reduced by the expected impact of inflation. Generally, the value of an inflation-protected security will fall when real interest rates rise and will rise when real interest rates fall.

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.

Risks of Investing for Inflation Protection: Because the interest and/or principal payments on an inflation-protected security are adjusted periodically for changes in inflation, the income distributed by a fund investing in such securities may be irregular. Although the U.S. Treasury guarantees to pay at maturity at least the original face value of any inflation-protected securities the Treasury issues, other issuers may not offer the same guarantee. Inflation-protected securities are not protected against deflation. As a result, in a period of deflation, the principal and income of inflation-protected securities held by a fund will decline and the fund may suffer a loss during such periods. While inflation-protected securities are expected to be protected from long-term inflationary trends, short-term increases in inflation may lead to a decline in the value of a fund holding such securities. For example, if interest rates rise due to reasons other than inflation, a fund’s investment in these securities may not be protected to the extent that the increase is not reflected in the securities’ inflation measures. In addition, positive adjustments to principal generally will result in taxable income to a fund at the time of such adjustments (which generally would be distributed by the fund as part of its taxable dividends), even though the principal amount is not paid until maturity. The current market value of inflation-protected securities is not guaranteed and will fluctuate.

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.

Derivatives Risk: Derivatives are instruments, such as futures contracts, and options thereon, whose value is derived from that of other assets, rates or indices. 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 the risk of improper valuation. Changes in the 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 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.

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 will continue to be met.

Premium/Discount Risk: The net asset value (“NAV”) of a fund 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 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.

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.

Operational Risk: Operational risks include human error, changes in personnel, system changes, faults in communication, and failures in systems, technology, or processes. 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.

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 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.

The investment objective of the Dimensional Global Core Plus Fixed Income ETF (the “Global Core Plus Fixed Income ETF” or “Portfolio”) is to seek to maximize total returns. Total return is comprised of income and capital appreciation.

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.

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. The costs for the Portfolio reflect the net expenses of the Portfolio that result from the contractual expense waiver in the first year only. Although your actual costs may be higher or lower, based on these assumptions your costs whether you redeem or hold your shares would be:

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 Portfolio 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. Because the Portfolio is new, information about portfolio turnover rate is not yet available.

The Global Core Plus Fixed Income ETF seeks to achieve its investment objective by investing in a universe of U.S. and foreign debt securities. The Portfolio may invest in obligations issued or guaranteed by the U.S. and foreign governments, their agencies and instrumentalities, including mortgage-backed securities, corporate debt obligations, bank obligations, commercial paper, repurchase agreements, money market funds, securities of domestic or foreign issuers denominated in U.S. dollars but not trading in the United States, and obligations of supranational organizations. The Portfolio may purchase or sell mortgage-backed securities on a delayed delivery or forward commitment basis through the “to-be-announced” (TBA) market. At the present time, the Advisor expects that the Portfolio will primarily invest in the obligations of issuers that are in developed countries. However, the Advisor may invest in issuers located in other countries as well, which may include emerging markets. The Advisor selects the Portfolio's foreign country and currency compositions based on an evaluation of various factors, including, but not limited to, relative interest rates and exchange rates.

The Portfolio may invest in fixed income securities 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 Investor’s Service, Inc. (“Moody’s”)) and in lower-rated (i.e., below investment grade, also known as “junk” bonds) fixed income securities. The Portfolio may invest with an emphasis on fixed income securities rated A+ to BBB- by S&P or Fitch or A1 to Baa3 by Moody’s. The Portfolio will be managed with a view to capturing expected credit premiums and expected term premiums. The term “expected credit premium” means the expected incremental return on investment for holding obligations considered to have greater credit risk than direct obligations of the U.S. Treasury, and “expected term premium” means the expected relative return on investment for holding securities having longer-term maturities as compared to shorter-term maturities. In managing the Portfolio, the Advisor will increase or decrease investment exposure to intermediate-term securities depending on the expected term premium and also increase or decrease investment exposure to lower-rated investment grade securities (i.e., those rated A+ to BBB- by S&P or Fitch or A1 to Baa3 by Moody’s) depending on the expected credit premium.

The Portfolio primarily invests in securities that mature within twenty years from the date of settlement, but may, as in the case of mortgage-backed securities, invest in securities with longer maturities. Under normal circumstances, the Portfolio will generally maintain a weighted average duration of no more than one half year greater than, and no less than one year below, the weighted average duration of the Bloomberg Global Aggregate Bond Index (hedged to USD), which was approximately 6.70 years as of December 31, 2023. From time to time, the Portfolio may deviate from this duration range when the Advisor determines it to be appropriate under the circumstances. Duration is a measure of the sensitivity of a security’s price to changes in interest rates. The longer a security’s duration, the more sensitive it will be to changes in interest rates. 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 intends to invest its assets to gain exposure to at least three different countries, including the United States. Under normal circumstances, the Portfolio invests at least 30% of its net assets in non-U.S. issuers. As of the date of the Prospectus, the Portfolio invests approximately 45% of its net assets in U.S. issuers. This percentage will change due to market conditions. An issuer may be considered to be of a country if it is organized under the laws of, maintains its principal place of business in, has at least 50% of its assets or derives at least 50% of its operating income in, or is a government, government agency, instrumentality or central bank of, that country. As a non-fundamental policy, under normal circumstances, the Portfolio will invest at least 80% of its net assets in fixed income securities.

Because many of the Portfolio’s investments may be denominated in foreign currencies, the Portfolio may enter into foreign currency forward contracts to attempt to protect against uncertainty in the level of future foreign currency rates, to hedge against fluctuations in currency exchange rates or to transfer balances from one currency to another. The Portfolio also may enter into credit default swaps on issuers or indices to buy or sell credit protection to hedge its credit exposure; gain market or issuer exposure without owning the underlying securities; or increase the Portfolio’s total return. The Portfolio may purchase or sell futures contracts and options on futures contracts, to hedge its interest rate or currency exposure or for non-hedging purposes, such as a substitute for direct investment or to increase or decrease market exposure, including adjustments 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.

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

Emerging Markets Risk: Numerous emerging market countries have a history of, and continue to experience serious, and potentially continuing, economic and political problems. Stock markets in many emerging market countries are relatively small, expensive to trade in and generally have higher risks than those in developed markets. Securities in emerging markets also may be less liquid than those in developed markets and foreigners are often limited in their ability to invest in, and withdraw assets from, these markets. Additional restrictions may be imposed under other conditions. Frontier market countries generally have smaller economies or less developed capital markets and, as a result, the risks of investing in emerging market countries are magnified in frontier market countries.

China Investments Risk: There are special risks associated with investments in China and Taiwan, which are considered emerging market countries by the Advisor. The Chinese government has implemented significant economic reforms in order to liberalize trade policy, promote foreign investment in the economy, reduce government control of the economy and develop market mechanisms. But there can be no assurance that these reforms will continue or that they will be effective. Despite reforms and privatizations of companies in certain sectors, the Chinese government still exercises substantial influence over many aspects of the private sector and may own or control many companies. The Chinese government continues to maintain a major role in economic policy making and investing in China involves risks of losses due to expropriation, nationalization, confiscation of assets and property, and the imposition of restrictions on foreign investments and on repatriation of capital invested.

A reduction in spending on Chinese products and services or the institution of additional tariffs or other trade barriers, including as a result of heightened trade tensions between China and the United States may also have an adverse impact on the Chinese economy. In addition, investments in Taiwan could be adversely affected by its political and economic relationship with China. Certain securities issued by companies located or operating in China, such as China A-shares, are also subject to trading restrictions, quota limitations and less market liquidity, which could pose risks to a fund investing in such securities. In addition, investments in special structures that utilize contractual arrangements to provide exposure to certain Chinese companies, known as variable interest entities (“VIEs”), that operate in sectors in which China restricts and/or prohibits foreign investments may present additional risks. The Chinese government’s acceptance of the VIE structure is evolving. It is uncertain whether Chinese officials and regulators will withdraw their acceptance of the structure generally, or with respect to certain industries, or whether Chinese courts or arbitration bodies would decline to enforce the contractual rights of foreign investors, each of which would likely have significant, detrimental, and possibly permanent losses on the value of such investments.

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.

High Yield Risk: Securities rated below investment grade may be subject to greater interest rate, credit, and liquidity risks than investment grade securities. Fixed income securities that are below investment grade involve high credit risk and are considered speculative. Below investment grade fixed income securities may also fluctuate in value more than higher quality fixed income securities and, during periods of market volatility, may be more difficult to sell at the time and price a fund desires.

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. Credit risk is greater for fixed income securities with ratings below investment grade (e.g., BB+ or below by S&P or Fitch or Ba1 or below by Moody’s). Fixed income securities that are below investment grade involve high credit risk and are considered speculative. Below investment grade fixed income securities may also fluctuate in value more than higher quality fixed income securities and, during periods of market volatility, may be more difficult to sell at the time and price the Portfolio desires.

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.

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). The Portfolio hedges foreign currency risk.

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.

Mortgage-Backed Securities Risk: Mortgage-backed securities represent interests in “pools” of mortgages and often involve risks that are different from or potentially more significant than risks associated with other types of debt instruments. Mortgage securities differ from typical debt securities in that principal is not paid back at maturity, but rather periodically over the life of the security. A fund may receive unscheduled payments of principal due to voluntary prepayments, refinancings or foreclosures on the underlying mortgage loans. When interest rates decline, borrowers may pay off their mortgages sooner than expected. This can reduce the returns of a fund because it may have to reinvest that money at the lower prevailing interest rates. As a result, mortgage securities may be less effective than some other types of debt securities as a means of securing long-term interest rates and may have less potential for capital appreciation during periods of falling interest rates. Conversely, in a period of rising interest rates, a fund may exhibit additional volatility since rising interest rates tend to extend the duration of fixed rate mortgage-related securities, making them more sensitive to changes in interest rates. As interest rates rise mortgage borrowers are less likely to exercise prepayment options, which may reduce the value of these securities and potentially cause a fund to lose money. This is known as extension risk.

Derivatives Risk: Derivatives are instruments, such as swaps, futures contracts, and options thereon, and foreign currency forward contracts, 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. In regard to currency hedging, it is generally not possible to precisely match the foreign currency exposure of such foreign currency forward contracts to the value of the securities involved due to fluctuations in the market values of such securities and cash flows into and out of a fund between the date a foreign currency forward contract is entered into and the date it expires. 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 the risk of improper valuation. Changes in the 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. Additional risks are associated with the use of swaps including counterparty and credit risk (the risk that the other party to a swap agreement will not fulfill its contractual obligations, whether because of bankruptcy or other default) and liquidity risk (the possible lack of a secondary market for the swap agreement). Credit risk increases when a fund is the seller of swaps and counterparty risk increases when the fund is a buyer of swaps. In addition, where a fund is the seller of swaps, it may be required to liquidate portfolio securities at inopportune times in order to meet payment obligations. Swaps may be illiquid or difficult to value.

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 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.

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 will continue to be met.

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 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 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. 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.

The Global ex US Core Fixed Income ETF seeks its investment objective by investing primarily in a universe of foreign debt securities. The Portfolio may invest in obligations issued or guaranteed by foreign governments, their agencies and instrumentalities, corporate debt obligations, bank obligations, commercial paper, repurchase agreements, money market funds, and obligations of supranational organizations. At the present time, the Advisor expects that the Portfolio will primarily invest in the obligations of issuers that are in developed countries. However, the Advisor may invest in issuers located in other countries as well, which may include emerging markets. The Advisor selects the Portfolio’s foreign country and currency compositions based on an evaluation of various factors, including, but not limited to, relative interest rates and exchange rates.

The Portfolio may invest in fixed income securities 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 Investor's Service, Inc. ("Moody's")). The Portfolio may invest with an emphasis on fixed income securities rated A+ to BBB- by S&P or Fitch or A1 to Baa3 by Moody's. The Portfolio will be managed with a view to capturing expected credit premiums and expected term premiums.

The Portfolio intends to invest its assets to gain exposure to at least three different countries, excluding the United States. As a non-fundamental policy, under normal circumstances, the Portfolio will invest at least 80% of its net assets in fixed income securities.

Generally, the Portfolio will purchase fixed income securities that mature within twenty years from the date of settlement. Under normal circumstances, the Portfolio will generally maintain a weighted average duration of no more than one half year greater than, and no less than one year below, the weighted average duration of the Bloomberg Global Aggregate ex-USD Bond Index (Hedged to USD), which was approximately 7.16 years as of December 31, 2023. From time to time, the Portfolio may deviate from this duration range when the Advisor determines it to be appropriate under the circumstances. Duration is a measure of the sensitivity of a security’s price to changes in interest rates. The longer a security’s duration, the more sensitive it will be to changes in interest rates.

Because many of the Portfolio’s investments may be denominated in foreign currencies, the Portfolio may enter into foreign currency forward contracts to attempt to protect against uncertainty in the level of future foreign currency rates, to hedge against fluctuations in currency exchange rates or to transfer balances from one currency to another. The Portfolio also may enter into credit default swaps on issuers or indices to buy or sell credit protection to hedge its credit exposure; gain market or issuer exposure without owning the underlying securities; or increase the Portfolio's total return. The Portfolio may purchase or sell futures contracts and options on futures contracts, to hedge its interest rate or currency exposure or for non-hedging purposes, such as a substitute for direct investment or to increase or decrease market exposure, including adjustments 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.

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

Emerging Markets Risk: Numerous emerging market countries have a history of, and continue to experience serious, and potentially continuing, economic and political problems. Stock markets in many emerging market countries are relatively small, expensive to trade in and generally have higher risks than those in developed markets. Securities in emerging markets also may be less liquid than those in developed markets and foreigners are often limited in their ability to invest in, and withdraw assets from, these markets. Additional restrictions may be imposed under other conditions. Frontier market countries generally have smaller economies or less developed capital markets and, as a result, the risks of investing in emerging market countries are magnified in frontier market countries.

China Investments Risk: There are special risks associated with investments in China and Taiwan, which are considered emerging market countries by the Advisor. The Chinese government has implemented significant economic reforms in order to liberalize trade policy, promote foreign investment in the economy, reduce government control of the economy and develop market mechanisms. But there can be no assurance that these reforms will continue or that they will be effective. Despite reforms and privatizations of companies in certain sectors, the Chinese government still exercises substantial influence over many aspects of the private sector and may own or control many companies. The Chinese government continues to maintain a major role in economic policy making and investing in China involves risks of losses due to expropriation, nationalization, confiscation of assets and property, and the imposition of restrictions on foreign investments and on repatriation of capital invested.

A reduction in spending on Chinese products and services or the institution of additional tariffs or other trade barriers, including as a result of heightened trade tensions between China and the United States may also have an adverse impact on the Chinese economy. In addition, investments in Taiwan could be adversely affected by its political and economic relationship with China. Certain securities issued by companies located or operating in China, such as China A-shares, are also subject to trading restrictions, quota limitations and less market liquidity, which could pose risks to a fund investing in such securities. In addition, investments in special structures that utilize contractual arrangements to provide exposure to certain Chinese companies, known as variable interest entities (“VIEs”), that operate in sectors in which China restricts and/or prohibits foreign investments may present additional risks. The Chinese government’s acceptance of the VIE structure is evolving. It is uncertain whether Chinese officials and regulators will withdraw their acceptance of the structure generally, or with respect to certain industries, or whether Chinese courts or arbitration bodies would decline to enforce the contractual rights of foreign investors, each of which would likely have significant, detrimental, and possibly permanent losses on the value of such investments.

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, including a governmental entity, 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 a fund’s performance.

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.

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). The Portfolio hedges foreign currency risk.

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.

Derivatives Risk: Derivatives are instruments, such as swaps, futures contracts, and options thereon, and foreign currency forward contracts, 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. In regard to currency hedging, it is generally not possible to precisely match the foreign currency exposure of such foreign currency forward contracts to the value of the securities involved due to fluctuations in the market values of such securities and cash flows into and out of a fund between the date a foreign currency forward contract is entered into and the date it expires. 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 the risk of improper valuation. Changes in the 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. Additional risks are associated with the use of swaps including counterparty and credit risk (the risk that the other party to a swap agreement will not fulfill its contractual obligations, whether because of bankruptcy or other default) and liquidity risk (the possible lack of a secondary market for the swap agreement). Credit risk increases when a fund is the seller of swaps and counterparty risk increases when the fund is a buyer of swaps. In addition, where a fund is the seller of swaps, it may be required to liquidate portfolio securities at inopportune times in order to meet payment obligations. Swaps may be illiquid or difficult to value.

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 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.

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 will continue to be met.

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 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 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. 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 information is not available for the Portfolio because it has not yet completed a full calendar year of operations. Updated performance information for the Portfolio can be obtained in the future by visiting https://www.dimensional.com/us-en/funds.

The investment objective of the Dimensional Global Credit ETF (the “Global Credit ETF” or “Portfolio”) is to seek to maximize total returns. Total return is comprised of income and capital appreciation.

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.

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. The costs for the Portfolio reflect the net expenses of the Portfolio that result from the contractual expense waiver in the first year only. Although your actual costs may be higher or lower, based on these assumptions your costs whether you redeem or hold your shares would be:

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 Portfolio 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. Because the Portfolio is new, information about portfolio turnover rate is not yet available.

The Global Credit ETF seeks to maximize total returns primarily from a universe of U.S. and foreign corporate debt securities that mature within twenty years from the date of settlement. In addition, the Portfolio may invest in obligations issued or guaranteed by the U.S. and foreign governments, their agencies and instrumentalities, bank obligations, commercial paper, repurchase agreements, money market funds, obligations of other domestic and foreign issuers, securities of domestic or foreign issuers denominated in U.S. dollars but not trading in the United States, and obligations of supranational organizations. The Advisor expects that the Portfolio will primarily invest in the obligations of issuers that are in developed countries. The Advisor selects the Portfolio's foreign country and currency compositions based on an evaluation of various factors, including, but not limited to, relative interest rates and exchange rates.

The Portfolio intends to invest its assets to gain exposure to at least three different countries, including the United States. Under normal circumstances, the Portfolio invests at least 30% of its net assets in non-U.S. issuers. As of the date of the Prospectus, the Portfolio invests approximately 62% of its net assets in U.S. issuers. This percentage will change due to market conditions. An issuer may be considered to be of a country if it is organized under the laws of, maintains its principal place of business in, has at least 50% of its assets or derives at least 50% of its operating income in, or is a government, government agency, instrumentality, or central bank of, that country. As a non-fundamental policy, under normal circumstances, the Portfolio will invest at least 80% of its net assets in debt securities.

The Portfolio generally emphasizes investments in debt securities rated A+ to BBB- by S&P Global Ratings (“S&P”) or Fitch Ratings Ltd. (“Fitch”) or A1 to Baa3 by Moody’s Investor’s Service, Inc. (“Moody’s”). The Portfolio may also invest in higher-rated investment grade securities (i.e., those rated AAA to AA- by S&P or Fitch or Aaa to Aa3 by Moody’s) and/or below-investment grade securities (i.e., those rated below BBB- by S&P or Fitch or below Baa3 by Moody’s) depending on the expected credit premium.

Under normal circumstances, the Portfolio will generally maintain a weighted average duration of no more than one half year greater than, and no less than one year below, the weighted average duration of the Bloomberg Global Aggregate Credit Bond Index (Hedged to USD), which was approximately 6.07 years as of December 31, 2023. From time to time, the Portfolio may deviate from this duration range when the Advisor determines it to be appropriate under the circumstances. Duration is a measure of the sensitivity of a security’s price to changes in interest rates. The longer a security’s duration, the more sensitive it will be to changes in interest rates.

The Portfolio’s investments may include foreign securities denominated in foreign currencies. The Portfolio intends to hedge foreign currency exposure to attempt to protect against uncertainty in the level of future foreign currency rates. The Portfolio may enter into foreign currency forward contracts to hedge against fluctuations in currency exchange rates or to transfer balances from one currency to another. The Portfolio also may enter into credit default swaps on issuers or indices to buy or sell credit protection to hedge its credit exposure; gain market or issuer exposure without owning the underlying securities; or increase the Portfolio’s total return. The Portfolio may purchase or sell futures contracts and options on futures contracts, to hedge its currency exposure or 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.

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

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.

High Yield Risk: Securities rated below investment grade may be subject to greater interest rate, credit, and liquidity risks than investment grade securities. Fixed income securities that are below investment grade involve high credit risk and are considered speculative. Below investment grade fixed income securities may also fluctuate in value more than higher quality fixed income securities and, during periods of market volatility, may be more difficult to sell at the time and price a fund desires.

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. Credit risk is greater for fixed income securities with ratings below investment grade (e.g., BB+ or below by S&P or Fitch or Ba1 or below by Moody’s). Fixed income securities that are below investment grade involve high credit risk and are considered speculative. Below investment grade fixed income securities may also fluctuate in value more than higher quality fixed income securities and, during periods of market volatility, may be more difficult to sell at the time and price the Portfolio desires.

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.

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). The Portfolio hedges foreign currency risk.

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.

Derivatives Risk: Derivatives are instruments, such as swaps, futures contracts, and options thereon, and foreign currency forward contracts, 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. In regard to currency hedging, it is generally not possible to precisely match the foreign currency exposure of such foreign currency forward contracts to the value of the securities involved due to fluctuations in the market values of such securities and cash flows into and out of a fund between the date a foreign currency forward contract is entered into and the date it expires. 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 the risk of improper valuation. Changes in the 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. Additional risks are associated with the use of swaps including counterparty and credit risk (the risk that the other party to a swap agreement will not fulfill its contractual obligations, whether because of bankruptcy or other default) and liquidity risk (the possible lack of a secondary market for the swap agreement). Credit risk increases when a fund is the seller of swaps and counterparty risk increases when the fund is a buyer of swaps. In addition, where a fund is the seller of swaps, it may be required to liquidate portfolio securities at inopportune times in order to meet payment obligations. Swaps may be illiquid or difficult to value.

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 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.

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 will continue to be met.

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 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 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. 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.

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 period September 26, 2023 to October 31, 2023, the Portfolio's portfolio turnover rate was 0% of the average value of its investment portfolio.

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 maturity that will not exceed one year. In making purchase decisions, if the expected term premium is greater for longer-term securities in the eligible maturity range, 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 Investor’s Service, Inc. (“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.

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 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.

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 will continue to be met.

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 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 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. 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.

The investment objective of the Dimensional National Municipal Bond ETF (the “Municipal Bond ETF” or “Portfolio”) is to seek to provide current income that is expected to be exempt from federal personal income tax.

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.

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. The costs for the Portfolio reflect the net expenses of the Portfolio that result from the contractual expense waiver in the first year only. Although your actual costs may be higher or lower, based on these assumptions your costs whether you redeem or hold your shares would be:

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 9% of the average value of its investment portfolio.

The Municipal Bond ETF will seek to achieve its investment objective by investing primarily in a universe of investment grade municipal securities, the interest on which is exempt from regular federal income tax. Municipal

securities in which the Portfolio may invest include, among others, revenue bonds, general obligation bonds, industrial development bonds, municipal lease obligations, commercial paper, variable rate demand obligations and other instruments (including participation interests in such securities) issued by or on behalf of the states, territories and possessions of the United States (including the District of Columbia) and their political subdivisions, agencies and instrumentalities. The interest on the municipal securities purchased by the Portfolio, in the opinion of bond counsel for the issuers and under current tax law, is exempt from federal income tax (i.e., excludable from gross income for individuals for federal income tax purposes but not necessarily exempt from state or local taxes). As a fundamental investment policy, under normal market conditions, the Portfolio will invest at least 80% of its net assets in municipal securities that pay interest exempt from federal income tax. The Portfolio does not currently intend to invest its assets in municipal securities whose interest is subject to the federal alternative minimum tax.

Under normal circumstances, the Portfolio will generally maintain a weighted average duration of no more than one half year greater, and no less than one year below, the average duration of the S&P Intermediate Term National AMT-Free Municipal Bond Index, which was approximately 3.86 years as of December 31, 2023. In making purchase decisions, if the expected term premium is greater for longer-term securities, the Advisor will focus investment in longer-term securities, otherwise, the Portfolio will focus investment in shorter-term securities. If a security has been redeemed by the issuer at a date prior to the stated final maturity date for the purposes of the above duration restriction, the early redemption date shall be considered the maturity date regardless of the stated final maturity. Duration is a measure of the sensitivity of a security’s price to changes in interest rates. The longer a security’s duration, the more sensitive it will be to changes in interest rates.

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 Investor’s Service, Inc. (“Moody’s”) or an equivalent rating assigned by another nationally recognized statistical rating organization, or that are unrated but have been determined by the Advisor to be of comparable quality). Municipal securities are often issued to obtain funds for various public purposes, including the construction of a wide range of public facilities, such as bridges, highways, housing, hospitals, mass transportation facilities, schools, streets and public utilities, such as water and sewer works. Municipal securities include municipal leases, certificates of participation, municipal obligation components and municipal custody receipts. The Portfolio may invest more than 25% of its assets in municipal securities issued to finance projects in a particular segment of the bond market including, but not limited to, health care, housing, education, utilities, and transportation. The Portfolio also may invest more than 25% of its assets in industrial development bonds.

The Portfolio may (1) purchase certain municipal securities that are insured, (2) invest in municipal securities secured by mortgages on single-family homes and multi-family projects, (3) invest in pre-refunded municipal securities, (4) purchase tax-exempt municipal securities on a “when-issued” basis, and (5) use fixed income related futures and options contracts, credit default swaps and interest rate swaps to hedge against changes in interest rates. The Portfolio may also invest in exchange-traded funds (ETFs) to gain exposure to the municipal bond market pending investment in municipal bonds. The Portfolio may also invest in money market funds. The Portfolio also 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 or outflows from the Portfolio.

Although the Portfolio attempts to invest all of its assets in tax-exempt securities, it is possible, although not anticipated, that a portion of its assets may be invested in securities that pay taxable interest, including interest that may be subject to the federal alternative minimum tax. These investments could generate taxable income for shareholders.

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.

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

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, including a governmental entity, 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. The ability of a municipal securities issuer to make payments could be affected by litigation, legislation or other political events or the bankruptcy of the issuer.

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.

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.

Tax Liability Risk: Tax liability risk is the risk that distributions by a fund become taxable to shareholders due to noncompliant conduct by a municipal bond issuer, unfavorable changes in federal or state tax laws, or adverse interpretations of tax laws by the Internal Revenue Service or state tax authorities or other factors. Such adverse interpretations or actions could cause interest from a security to become taxable, possibly retroactively, subjecting shareholders to increased tax liability. In addition, such adverse interpretations or actions could cause the value of a security, and therefore, the value of a fund’s shares, to decline.

Municipal Securities Risk: The risk of a municipal security generally depends on the financial and credit status of the issuer. Municipal securities can be significantly affected by political, regulatory or economic changes, including changes made in the law after issuance of the securities, as well as uncertainties in the municipal market related to taxation, legislative changes or the rights of municipal security holders, including in connection with an issuer’s insolvency.

Municipal Project-Specific Risk: A fund may be more sensitive to adverse economic, business or political developments if it invests a substantial portion of its assets in municipal securities that finance similar types of projects in a segment of the municipal bond market (such as education, health care, housing, education, utilities or transportation) or industrial development bonds. A change that affects one project in a particular segment of the market, such as proposed legislation on the financing of the project, a shortage of the materials needed for the project, or a declining need for the project, would likely affect all similar projects, thereby increasing market risk.

Derivatives Risk: Derivatives are instruments, such as swaps, 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, liquidity, interest rate, market, credit and management risks, as well as the risk of improper valuation. Changes in the 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. Additional risks are associated with the use of swaps including counterparty and credit risk (the risk that the other party to a swap agreement will not fulfill its contractual obligations, whether because of bankruptcy or other default) and liquidity risk (the possible lack of a secondary market for the swap agreement). Credit risk increases when a fund is the seller of swaps and counterparty risk increases when the fund is a buyer of swaps. In addition, where a fund is the seller of swaps, it may

be required to liquidate portfolio securities at inopportune times in order to meet payment obligations. Swaps may be illiquid or difficult to value. Additionally, payments made or received by a fund under such derivatives may increase the amount of distributions taxable to you as ordinary income, increase or decrease the amount of capital gain distributions to you and/or decrease the amount available for distribution to you as exempt-interest dividends.

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 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.

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 will continue to be met.

Premium/Discount Risk: The net asset value (“NAV”) of a fund 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 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. 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.

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.

The investment objective of the Dimensional California Municipal Bond ETF (the “California Municipal Bond ETF” or “Portfolio”) is to seek to provide current income that is expected to be exempt from federal personal income tax and California state personal income taxes.

The California Municipal Bond ETF will seek to achieve its investment objective by investing primarily in a universe of investment grade municipal securities, the interest on which is exempt from regular federal income tax and the state personal income tax of California. Municipal securities in which the Portfolio may invest include, among others, revenue bonds, general obligation bonds, industrial development bonds, municipal lease obligations, commercial paper, variable rate demand obligations and other instruments (including participation interests in such securities) issued by or on behalf of California state or local governments and their agencies, instrumentalities, and regional government authorities. The interest on the municipal securities purchased by the Portfolio, in the opinion of bond counsel for the issuers and under current tax law, is exempt from California and federal personal income taxes (i.e., excludable from gross income for individuals for California and federal income tax purposes).

The Portfolio does not currently intend to invest its assets in municipal securities whose interest is subject to the federal alternative minimum tax.

Under normal circumstances, the Portfolio will generally maintain a weighted average duration of no more than one half year greater than, and no less than one year below, the average duration of the S&P Intermediate Term California AMT-Free Municipal Bond Index, which was approximately 3.91 years as of December 31, 2023. In making purchase decisions, if the expected term premium is greater for longer-term securities, the Advisor will focus investment in longer-term securities, otherwise, the Portfolio will focus investment in shorter-term securities.

The Portfolio is primarily designed for investment by California taxpayers.

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

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.

The ability of a municipal securities issuer to make payments could be affected by litigation, legislation or other political events or the bankruptcy of the issuer.

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.

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.

Tax Liability Risk: Tax liability risk is the risk that distributions by a fund become taxable to shareholders due to noncompliant conduct by a municipal bond issuer, unfavorable changes in federal or state tax laws, or adverse interpretations of tax laws by the Internal Revenue Service or state tax authorities or other factors. Such adverse interpretations or actions could cause interest from a security to become taxable, possibly retroactively, subjecting shareholders to increased tax liability. In addition, such adverse interpretations or actions could cause the value of a security, and therefore, the value of a fund’s shares, to decline.

Municipal Securities Risk: The risk of a municipal security generally depends on the financial and credit status of the issuer. Municipal securities can be significantly affected by political, regulatory or economic changes, including changes made in the law after issuance of the securities, as well as uncertainties in the municipal market related to taxation, legislative changes or the rights of municipal security holders, including in connection with an issuer’s insolvency.

Municipal Project-Specific Risk: A fund may be more sensitive to adverse economic, business or political developments if it invests a substantial portion of its assets in municipal securities that finance similar types of projects in a segment of the municipal bond market (such as education, health care, housing, education, utilities or transportation) or industrial development bonds. A change that affects one project in a particular segment of the market, such as proposed legislation on the financing of the project, a shortage of the materials needed for the project, or a declining need for the project, would likely affect all similar projects, thereby increasing market risk.

State-Specific Risk: A fund that focuses its investments primarily in California municipal securities will be highly sensitive to events affecting the fiscal stability of the State of California and its agencies, municipalities, authorities and other instrumentalities that issue securities. Having a significant percentage of its assets invested in the securities of fewer issuers, particularly obligations of government issuers of a single state, could result in greater credit risk exposure to a smaller number of issuers due to economic, regulatory or political problems in California.

These issues may include economic or political policy changes, tax base erosion, unfunded pension and healthcare liabilities, state constitutional limits on tax increases, budget deficits and other financial difficulties, and changes in the credit ratings assigned to municipal issuers of California. Also, to the extent that a fund makes significant investments in securities issued to finance projects in a particular segment of the California municipal securities market such focused investment may cause the value of the fund’s shares to change more than the value of shares of funds that invest more broadly. These risks are disclosed in more detail in the Portfolio’s Statement of Additional Information.

Derivatives Risk: Derivatives are instruments, such as swaps, futures contracts, and options thereon, whose value is derived from that of other assets, rates or indices.
