**Investment Objective**

The fund seeks long-term capital appreciation.

**Fees and Expenses**

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

---

| | |
|:---|:---|
| **Annual Fund Operating Expenses** (expenses that you pay each year as a percentage of the value of your investment) | **Annual Fund Operating Expenses** (expenses that you pay each year as a percentage of the value of your investment) |
| Management Fee | 0.05% |
| Other Expenses | 0.00% |
| Acquired Fund Fees and Expenses | 0.20% |
| Total Annual Fund Operating Expenses | 0.25% |
| Fee Waiver<sup>1</sup> | 0.02% |
| Total Annual Fund Operating Expenses After Waiver | 0.23% |

---

<sup>1</sup>*&nbsp;&nbsp;&nbsp;&nbsp;The advisor has agreed to waive 0.02 percentage points of the fund's management fee. The advisor expects this waiver to continue until <br>December 31, 2026 and cannot terminate it prior to such date without the approval of the Board of Trustees.*

**Example**

The example below is intended to help you compare the costs of investing in the fund with the costs of investing in other funds. The example assumes that you invest $10,000 in the fund for the time periods indicated and then redeem all of your shares at the end of those periods, that you earn a 5% return each year, and that the fund's operating expenses remain the same, except that it reflects the rate and duration of any fee waivers noted in the table above. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

---

| | | | |
|:---|:---|:---|:---|
| *1 year* | *3 years* | *5 years* | *10 years* |
| $24 | $79 | $139 | $317 |

---

------

**Portfolio Turnover**

The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in 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 fund's performance. During the most recent fiscal year, the fund's portfolio turnover rate was 0% of the average value of its portfolio.

**Principal Investment Strategies**

Avantis All Equity Markets ETF is a "fund of funds," meaning that it seeks to achieve its objective by investing in other Avantis exchange-traded funds (ETFs) (collectively, the underlying funds). The underlying funds represent a broadly diversified basket of equity securities that seek to overweight securities that are expected to have higher returns or better risk characteristics than a passive, market-cap weighted index.

The following table indicates the fund's target weight and range for allocation among the fund's major asset classes and shows the underlying funds that comprise each asset class. This information is as of the date of this prospectus.

---

Under normal market conditions, the fund will invest at least 80% of its assets in equity ETFs. The managers will strategically allocate to the underlying funds across geographies and investment styles to achieve the desired allocation. The U.S. vs. non-U.S. allocations across geographies will be predicated on each region's relative market capitalization with a home bias toward the U.S. The portfolio managers regularly review the fund's allocations to determine whether rebalancing is appropriate. To better balance risks in changing market environments and control costs and tax realizations, the portfolio managers may allocate within the target range in light of prevailing market conditions and relative performance. We reserve the right to modify the target ranges and underlying funds from time to time should circumstances warrant a change.

The fund is an actively managed exchange-traded fund (ETF) that does not seek to replicate the performance of a specified index. The portfolio managers continually analyze market and financial data to make buy, sell, and hold decisions.

**Principal Risks**

**• Allocation Risk —** The fund's performance and risks depend in part on the managers' skill in selecting and weighting the underlying funds, and implementing any deviations from the target range. The managers' evaluations and assumptions regarding asset classes or underlying funds may differ from actual market conditions.

**• Fund of Funds Risks —** The fund's performance and risks reflect the performance and risks of the underlying funds in which it invests. The fund's investment in other funds advised by American Century Investments may create a conflict of interest for the fund's advisor.

**• Equity Securities Risk —** The underlying funds invest in equity securities. The value of equity securities, may fluctuate due to changes in investor perception of a specific issuer, changes in the general condition of the stock market, or occurrences of

------

political or economic events that affect equity issuers and the market. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase.

**• Foreign Securities Risk —** Some of the underlying funds invest in foreign securities. Foreign securities are generally riskier than U.S. securities. Political events (such as civil unrest, national elections and imposition of exchange controls), social and economic events (such as labor strikes and rising inflation), and natural disasters occurring in a country where the fund invests could cause the fund's investments in that country to experience gains or losses. Securities of foreign issuers may be less liquid, more volatile and harder to value than U.S. securities.

**• Emerging Market Risk —** Some of the underlying funds invest in emerging markets securities. Investing in emerging market countries generally is riskier than investing in foreign developed countries. Emerging market countries may have unstable governments, economies that are subject to sudden change, and significant volatility in their financial markets. These countries also may lack the legal, business and social framework to support securities markets. Additionally, certain jurisdictions do not provide the Public Company Accounting Oversight Board (PCAOB) with sufficient access to inspect audit work papers and practices, or otherwise do not cooperate with U.S. regulators, potentially exposing investors in U.S. capital markets to significant risks.

**• ETF Risk —** ETF shares are based on market price rather than net asset value (NAV), as a result, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). The fund may also incur brokerage commissions, as well as the cost of the bid/ask spread, when purchase or selling ETF shares.

• **Small- and Mid-Cap Stock Risks —** Stocks of smaller companies may be more volatile than larger-company stocks. Smaller companies may have limited financial resources, product lines and markets, and their securities may trade less frequently and in more limited volumes than the securities of larger companies, which could lead to higher transaction costs. To the extent an underlying fund invests in these companies, it may take on more risk.

• **Cash Transactions Risk —** The fund may effect its creations and redemptions for cash, rather than for in-kind securities. Therefore, it may be required to sell portfolio securities and subsequently recognize gains on such sales that the fund might not have recognized if it were to distribute portfolio securities in-kind. As such, investments in fund shares may be less tax-efficient than an investment in an ETF that distributes portfolio securities entirely in-kind. Cash transactions may have to be carried out over several days if the securities market is relatively illiquid and may involve considerable brokerage fees and taxes. Brokerage fees and taxes will be higher than if the fund sold and redeemed shares in-kind.

**• Style Risk —** If at any time the market is not favoring the fund's investment style, the fund's gains may not be as big as, or its losses may be bigger than, those of other equity funds using different investment styles.

**• Market Trading Risk —** The fund faces numerous market trading risks, including the potential lack of an active market for fund shares, losses from trading in secondary markets, periods of high volatility and disruption in the creation and/or redemption process of the fund. Any of these factors, among others, may lead to the fund's shares trading at a premium or discount to NAV. Thus, you may pay more (or less) than NAV when you buy shares of the fund in the secondary market, and you may receive less (or more) than NAV when you sell those shares in the secondary market. The portfolio managers cannot predict whether shares will trade above (premium), below (discount) or at NAV.

**• Market Risk —** The value of the fund's shares will go up and down based on the performance of the underlying funds in which it invests. The value of the underlying funds' shares will, in turn, fluctuate based on the performance of the companies whose securities they own and other factors generally affecting the securities market. Market risks, including political, regulatory, economic and social developments, can affect the value of the fund's investments. Natural disasters, public health emergencies, war, terrorism and other unforeseeable events may lead to increased market volatility and may have adverse long-term effects on world economies and markets generally.

**• Real Estate Investing Risk —** If an underlying fund invests in real estate, it may be subject to many of the same risks as a direct investment in real estate. These risks include changes in economic conditions, interest rates, property values, property tax increases, overbuilding and increased competition, environmental contamination, zoning and natural disasters. This is due to the fact that the value of the fund's investments may be affected by the value of the real estate owned by the companies in which it invests. To the extent the fund invests in companies that make loans to real estate companies, the fund also may be subject to interest rate risk and credit risk.

**• Authorized Participant Concentration Risk —** Only an authorized participant may engage in creation or redemption transactions directly with the fund. The fund may have a limited number of institutions that act as authorized participants. To the extent that these institutions exit the business or are unable to proceed with creation and/or redemption orders with respect to the fund and no other authorized participant is able to step forward to process creation and/or redemption orders, fund shares may trade at a discount to net asset value (NAV) and possibly face trading halts and/or delisting. This risk may be more pronounced in volatile markets, potentially where there are significant redemptions in ETFs generally.

**• Price Volatility Risk —** The value of the fund's shares may fluctuate significantly in the short term.

------

**• Principal Loss Risk —** At any given time your shares may be worth less than the price you paid for them. In other words, it is possible to lose money by investing in the fund.

An investment in the fund is not a bank deposit, and it is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency.

After-tax returns 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. After-tax returns are not relevant to investors who hold their fund shares through tax-deferred arrangements, such as 401(k) plans or IRAs.

**Portfolio Management**

**Investment Advisor**

American Century Investment Management, Inc.

**Portfolio Managers**

**Eduardo Repetto,** Chief Investment Officer of Avantis Investors, has been a member of the team that manages the fund since its inception.

**Mitchell Firestein,** Senior Portfolio Manager, has been a member of the team that manages the fund since its inception.

**Daniel Ong,** Senior Portfolio Manager, has been a member of the team that manages the fund since its inception.

**Ted Randall,** Senior Portfolio Manager, has been a member of the team that manages the fund since its inception.

**Matthew Dubin**, Portfolio Manager, has been a member of the team that manages the fund since its inception.

**Purchase and Sale of Fund Shares**

The fund is an ETF. Fund shares may only be bought and sold in a secondary market through a broker-dealer at a market price. Because ETF shares trade at market prices rather than NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). An investor may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase shares of the fund (bid) and the lowest price a seller is willing to accept for shares of the fund (ask) when buying or selling shares in the secondary market (bid-ask spread). Investors can find information on the fund's NAV, market price, premiums and discounts, and bid-ask spread at avantisinvestors.com.

**Tax Information**

Fund distributions are generally taxable as ordinary income or capital gains, unless you are investing through a tax-deferred account such as a 401(k) or individual retirement account (in which case you may be taxed upon withdrawal of your investment from such account).

**Payments to Broker-Dealers and Other Financial Intermediaries**

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