President’s Letter

Dear Investor:

Thank you for reviewing this annual report for the period ended August 31, 2023. Annual reports help convey important information about fund returns, including market factors that affected performance. For additional investment insights, please visit americancentury.com.

Stocks Rebounded, Bonds Struggled

Asset class returns, particularly for U.S. and global stocks, improved dramatically compared with the previous fiscal year. The bounce back occurred despite ongoing volatility, rising interest rates and Fitch Ratings’ first-ever downgrade of U.S. debt.

Investor expectations for the Federal Reserve (Fed) to conclude its rate-hike campaign partly fueled the optimism. Inflation’s steady slowdown, mounting recession worries and a series of U.S. regional bank failures prompted investors to regularly recalibrate their monetary policy outlooks. However, with inflation still higher than central bank targets, the Fed and its developed markets peers continued to raise interest rates.

After pausing in June, the Fed resumed its tightening campaign in July, raising rates to a range of 5.25% to 5.5%, a 22-year high. Citing still-higher-than-target inflation and still-strong economic data, policymakers left their future policy options open. Inflation remained even higher in the eurozone and the U.K., prompting central bankers there to steadily raise interest rates. Government bond yields soared, including the benchmark 10-year Treasury yield, which surged to a 16-year high late in the period.

Despite the inflation and rate backdrops, better-than-expected corporate earnings helped the S&P 500 Index return 15.94% for the 12-month period. Non-U.S. developed markets stocks delivered modestly higher returns, while emerging markets stocks gained only 1.25%. Meanwhile, amid elevated inflation and sharply higher Treasury yields, most U.S. bond and other rate-sensitive sectors declined, though not as much as in the prior fiscal year. Exceptions included corporate and municipal bonds, which delivered modest gains.

Remaining Diligent in Uncertain Times

We expect market volatility to linger as investors navigate a complex environment of persistent inflation, tighter financial conditions, banking industry turbulence and recession risk. In addition, increasingly tense geopolitical considerations complicate the market backdrop.

We appreciate your confidence in us during these extraordinary times. American Century Investments has a long history of helping clients weather unpredictable and volatile markets, and we’re confident we will continue to meet today’s challenges.

Sincerely,

Portfolio Commentary

Portfolio Managers: Keith Lee, Michael Li, Henry He and Rene Casis

Performance Review

American Century Focused Dynamic Growth ETF returned 16.55% on a market price basis for its fiscal year ended August 31, 2023. On a net asset value (NAV) basis, the fund returned 16.70%. For the same time period, the Russell 1000 Growth Index, the fund’s benchmark, returned 21.94%. The fund’s NAV and market price returns reflect fees and operating expenses, while the index return does not.

Information Technology Stocks Detracted From Relative Performance

Our positioning in the information technology sector hampered performance, especially in the software industry. BILL Holdings, a provider of software for back-office functions, lagged despite strong revenue and improving earnings. Investors appeared to be more concerned about economic weakness hampering growth in the near term. Keysight Technologies manufactures test and measurement instruments for use in communications, networking and electronics applications. It posted mixed results with revenues and earnings that beat expectations, but new orders that lagged. The company also issued disappointing guidance. Cybersecurity firm Okta’s stock fell despite reporting better-than-expected revenues and earnings, in addition to substantial margin expansion. We would attribute the stock’s decline largely to disappointing forward guidance.

Other significant detractors included Paylocity Holding. This provider of cloud-based software for human resources and back-office functions reported better-than-expected revenue and earnings, but the stock lagged on profit-taking after strong performance. Tesla’s stock fell sharply in 2022 on concerns about softening demand and potential production disruptions in China amid protests over the country’s zero-COVID-19 policy. Although the electric vehicle maker rebounded in 2023, it ended the period as a notable detractor.

Energy Benefited Performance

Performance in the energy sector was led by Cactus. The company designs and manufactures wellheads and pressure control systems differentiated by their safety and efficiency. The stock rose after management announced a stock buyback program and offered strong forward guidance.

Elsewhere, NVIDIA was a top contributor. The chipmaker’s growth was driven by its data center business, which reflects the demand for computing power required for artificial intelligence applications. Intuitive Surgical’s stock rose as the maker of robotic surgical systems benefited from much better-than-expected procedure growth using its da Vinci system. Sales also remained strong given that a new system is on the horizon. Regeneron Pharmaceuticals was a top contributor. The biotechnology company outperformed, aided by Food and Drug Administration approval of a heavier dose treatment of Eylea, its drug for wet age-related macular degeneration. Unlike its original treatment, this heavier dose will not lose patent protection next year. The stock of Westinghouse Air Brake Technologies rose, aided by the strong results of its freight rail segment. Westinghouse Air Brake makes products for locomotives, freight cars and other transit vehicles, addressing safety improvement in mass transit markets.

Portfolio Commentary

Portfolio Managers: Kevin Toney, Michael Liss, Brian Woglom, Philip Sundell, Adam Krenn and Rene Casis

Phillip Davidson stepped down as a portfolio manager of Focused Large Cap Value ETF on December 31, 2022, and retired from American Century Investments on March 31, 2023.

Performance Summary

American Century Focused Large Cap Value ETF returned 9.49% on a market price basis over the 12-month period ending August 31, 2023. On a net asset value (NAV) basis, the fund returned 9.42%. The fund’s benchmark, the Russell 1000 Value Index, returned 8.59% during the same period. The fund’s market price and NAV returns reflect operating expenses, while the index’s return does not.

Financials and Health Care Were Areas of Strength

Security selection in the financials sector helped performance relative to the benchmark, particularly in the banking industry. Positions in the financial services and insurance industries also aided results, including insurance broker Marsh & McLennan Cos. Its shares advanced after the company announced better-than-expected financial results and expanded the scope of its cost-cutting program.

Our choice of investments in the health care sector was also beneficial, including our decision to avoid Pfizer. Shares of Pfizer were pressured by the cost of its Seagen acquisition and uncertainty about whether the deal will be approved. Also, demand for Pfizer’s COVID-19 vaccine and oral treatment subsided.

Other top contributors included TotalEnergies and nVent Electric. Shares of TotalEnergies, an integrated energy company, were buoyed by supportive oil and gas prices. Also, the company provided a strategic update that was well received by investors. Electrical equipment supplier nVent Electric was another top contributor. Its shares rose after strong pricing power helped the company deliver solid earnings results. nVent Electric also completed its acquisition of ECM Industries, which could potentially bolster future sales growth.

Communication Services and Industrials Detracted

Security selection and an underweight in the communication services sector hindered results. Notably, lack of exposure to Meta Platforms detracted. Shares of this technology conglomerate benefited from cost-cutting efforts and the company’s investments in artificial intelligence. We did not own the stock because our analysis showed that its risk/reward profile was less attractive than other names.

Stock selection in the industrials sector, coupled with the portfolio’s underweight in the sector relative to the benchmark, also hurt performance. Industrials holding RTX was a key detractor. Shares of this aerospace and defense company declined after the company announced the need for accelerated inspections on a metal disc in its aircraft engines. We view this as a transitory issue.

Truist Financial, a large regional bank, was another key detractor. The failure of two mid-capitalization banks in early 2023 led investors to worry about the broader banking system, leading to market volatility and pressuring shares of Truist and many other banks. Truist also reported lower-than-expected financial results, driven by a decline in net interest income and higher costs.

Shareholder Fee Examples

Fund shareholders may incur two types of costs: (1) transaction costs, including brokerage commissions paid on purchases and sales of fund shares; and (2) ongoing costs, including management fees and other fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in your fund and to compare these costs with the ongoing cost of investing in other funds.

The example is based on an investment of $1,000 made at the beginning of the period and held for the entire period from March 1, 2023 to August 31, 2023.

Actual Expenses

The table provides information about actual account values and actual expenses for each fund. You may use the information, together with the amount you invested, to estimate the expenses that you paid over the period. First, identify the fund you own. Then simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number under the heading “Expenses Paid During Period” to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes

The table also provides information about hypothetical account values and hypothetical expenses based on the actual expense ratio of your fund and an assumed rate of return of 5% per year before expenses, which is not the actual return of a fund. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in your fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as brokerage commissions paid on purchases and sales of fund shares. Therefore, the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

Annualized expense ratio reflects actual expenses, including any applicable fee waivers or expense reimbursements and excluding any acquired fund fees and expenses.

Notes to Financial Statements

AUGUST 31, 2023

1. Organization

American Century ETF Trust (the trust) was registered as a Delaware statutory trust in 2017 and is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company. American Century Focused Dynamic Growth ETF (Focused Dynamic Growth ETF) and American Century Focused Large Cap Value ETF (Focused Large Cap Value ETF) (collectively, the funds) are two funds in a series issued by the trust. Each fund's investment objective is to seek long-term capital growth. Shares of each fund are listed for trading on the Cboe BZX Exchange, Inc.

2. Significant Accounting Policies

The following is a summary of significant accounting policies consistently followed by the funds in preparation of their financial statements. Each fund is an investment company and follows accounting and reporting guidance in accordance with accounting principles generally accepted in the United States of America. This may require management to make certain estimates and assumptions at the date of the financial statements. Actual results could differ from these estimates. Management evaluated the impact of events or transactions occurring through the date the financial statements were issued that would merit recognition or disclosure.

Investment Valuations — The funds determine the fair value of their investments and compute their net asset value (NAV) per share at the close of regular trading (usually 4 p.m. Eastern time) on the New York Stock Exchange (NYSE) on each day the NYSE is open. The value of investments of the funds are determined by American Century Investment Management, Inc. (ACIM) (the investment advisor), as the valuation designee, pursuant to its valuation policies and procedures. The Board of Trustees oversees the valuation designee and reviews its valuation policies and procedures at least annually. 

Equity securities that are listed or traded on a domestic securities exchange are valued at the last reported sales price or at the official closing price as provided by the exchange. Equity securities traded on foreign securities exchanges are generally valued at the closing price of such securities on the exchange where primarily traded or at the close of the NYSE, if that is earlier. If no last sales price is reported, or if local convention or regulation so provides, the mean of the latest bid and asked prices may be used. Securities traded over-the-counter are valued at the mean of the latest bid and asked prices, the last sales price, or the official closing price.

Open-end management investment companies are valued at the reported NAV per share.

If the valuation designee determines that the market price for a portfolio security is not readily available or is believed by the valuation designee to be unreliable, such security is valued at fair value as determined in good faith by the valuation designee, in accordance with its policies and procedures. Circumstances that may cause the funds to determine that market quotations are not available or reliable include, but are not limited to: when there is a significant event subsequent to the market quotation; trading in a security has been halted during the trading day; or trading in a security is insufficient or did not take place due to a closure or holiday.

The valuation designee monitors for significant events occurring after the close of an investment’s primary exchange but before each fund’s NAV per share is determined. Significant events may include, but are not limited to: corporate announcements and transactions; regulatory news, governmental action and political unrest that could impact a specific investment or an investment sector; or armed conflicts, natural disasters and similar events that could affect investments in a specific country or region. The valuation designee also monitors for significant fluctuations between domestic and foreign markets, as evidenced by the U.S. market or such other indicators that it deems appropriate. The valuation designee may apply a model-derived factor to the closing price of equity securities traded on foreign securities exchanges. The factor is based on observable market data as provided by an independent pricing service.

Security Transactions — Security transactions are accounted for as of the trade date. Net realized gains and losses are determined on the identified cost basis, which is also used for federal income tax purposes.

17


Investment Income — Dividend income less foreign taxes withheld, if any, is recorded as of the ex-dividend date. Distributions received on securities that represent a return of capital or long-term capital gain are recorded as a reduction of cost of investments and/or as a realized gain. The funds may estimate the components of distributions received that may be considered nontaxable distributions or long-term capital gain distributions for income tax purposes. Interest income is recorded on the accrual basis and includes accretion of discounts and amortization of premiums. Securities lending income is net of fees and rebates earned by the lending agent for its services.

Income Tax Status — It is each fund's policy to distribute substantially all net investment income and net realized gains to shareholders and to otherwise qualify as a regulated investment company under provisions of the Internal Revenue Code. Accordingly, no provision has been made for income taxes. The funds file U.S. federal, state, local and non-U.S. tax returns as applicable. The funds' tax returns are subject to examination by the relevant taxing authority until expiration of the applicable statute of limitations, which is generally three years from the date of filing but can be longer in certain jurisdictions. At this time, management believes there are no uncertain tax positions which, based on their technical merit, would not be sustained upon examination and for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly change in the next twelve months.

Distributions to Shareholders — Distributions from net investment income, if any, are generally declared and paid quarterly. Distributions from net realized gains, if any, are generally declared and paid annually.

Indemnifications — Under the trust’s organizational documents, its officers and trustees are indemnified against certain liabilities arising out of the performance of their duties to the funds. In addition, in the normal course of business, the funds enter into contracts that provide general indemnifications. The maximum exposure under these arrangements is unknown as this would involve future claims that may be made against a fund. The risk of material loss from such claims is considered by management to be remote.

Securities Lending — Securities are lent to qualified financial institutions and brokers. State Street Bank & Trust Co. serves as securities lending agent to the funds pursuant to a Securities Lending Agreement. The lending of securities exposes the funds to risks such as: the borrowers may fail to return the loaned securities, the borrowers may not be able to provide additional collateral, the funds may experience delays in recovery of the loaned securities or delays in access to collateral, or the funds may experience losses related to the investment collateral. To minimize certain risks, loan counterparties pledge collateral in the form of cash and/or securities. The lending agent has agreed to indemnify the funds in the case of default of any securities borrowed. Cash collateral received is invested in the State Street Navigator Securities Lending Government Money Market Portfolio, a money market mutual fund registered under the 1940 Act. The loans may also be secured by U.S. government securities in an amount at least equal to the market value of the securities loaned, plus accrued interest and dividends, determined on a daily basis and adjusted accordingly. By lending securities, the funds seek to increase their net investment income through the receipt of interest and fees. Such income is reflected separately within the Statements of Operations. The value of loaned securities and related collateral outstanding at period end, if any, are shown on a gross basis within the Schedules of Investments and Statements of Assets and Liabilities.

The following table reflects a breakdown of transactions accounted for as secured borrowings, the gross obligation by the type of collateral pledged, and the remaining contractual maturity of those transactions as of August 31, 2023.

3. Fees and Transactions with Related Parties

Certain officers and trustees of the trust are also officers and/or directors of American Century Companies, Inc. (ACC). The trust's investment advisor, ACIM, and the trust’s administrator, American Century Services, LLC, are wholly owned, directly or indirectly, by ACC. Various funds issued by American Century Strategic Asset Allocations, Inc. own, in aggregate, 36% and 32% of the shares of Focused Dynamic Growth ETF and Focused Large Cap Value ETF, respectively. Related parties do not invest in the funds for the purpose of exercising management or control.

Management Fees — The trust has entered into a management agreement with ACIM, under which ACIM provides the funds with investment advisory and management services in exchange for a single, unified management fee (the fee). The agreement provides that ACIM will pay all expenses of managing and operating the funds, except brokerage and other transaction fees and expenses relating to the acquisition and disposition of portfolio securities, acquired fund fees and expenses, interest, taxes, litigation expenses and extraordinary expenses. The fee is computed and accrued daily based on the daily net assets of each fund and paid monthly in arrears. 

The annual management fee for each fund is as follows:
Annual Management Fee
Focused Dynamic Growth ETF 0.45%
Focused Large Cap Value ETF 0.42%

Interfund Transactions — The funds may enter into security transactions with other American Century Investments funds and other client accounts of the investment advisor, in accordance with the 1940 Act rules and procedures adopted by the Board of Trustees. The rules and procedures require, among other things, that these transactions be effected at the independent current market price of the security. There were no interfund transactions during the period.

4. Investment Transactions

Purchases and sales of investment securities, excluding short-term investments and in kind transactions, for the period ended August 31, 2023 were as follows:
Focused Dynamic
Growth ETF
Focused Large
Cap Value ETF
Purchases $80,623,884 $110,546,653
Sales $57,717,540 $91,158,680

Securities received or delivered in kind through subscriptions and redemptions and in kind net realized gain (loss) for the period ended August 31, 2023 were as follows:
In kind
Subscriptions
In kind
Redemptions

Net Realized

Focused Dynamic Growth ETF $6,196,114 $1,320,137
Focused Large Cap Value ETF $1,161,995 $29,514,480 $5,445,302
*Net realized gain (loss) on in kind transactions are not considered taxable for federal income tax purposes.

5. Capital Share Transactions

Each fund’s 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). Each fund issues and redeems shares at their NAV only in aggregations of a specified number of shares (a creation unit) generally in exchange for a designated portfolio of securities and/or cash (including any portion of such securities for which cash may be substituted). Authorized participants may be required to pay an additional variable charge to cover certain brokerage, tax, foreign exchange, execution, market impact and other costs and expenses related to the execution of trades resulting from creation unit transactions. Such variable charges, if any, are included in other capital within the Statements of Changes in Net Assets.

19


6. Fair Value Measurements

The funds' investment valuation process is based on several considerations and may use multiple inputs to determine the fair value of the investments held by the funds. In conformity with accounting principles generally accepted in the United States of America, the inputs used to determine a valuation are classified into three broad levels. 

• Level 1 valuation inputs consist of unadjusted quoted prices in an active market for identical investments.

• Level 2 valuation inputs consist of direct or indirect observable market data (including quoted prices for comparable investments, evaluations of subsequent market events, interest rates, prepayment speeds, credit risk, etc.). These inputs also consist of quoted prices for identical investments initially expressed in local currencies that are adjusted through translation into U.S. dollars. 

• Level 3 valuation inputs consist of unobservable data (including a fund’s own assumptions).

The level classification is based on the lowest level input that is significant to the fair valuation measurement. The valuation inputs are not necessarily an indication of the risks associated with investing in these securities or other financial instruments.

As of period end, the funds' investment securities were classified as Level 1. The Schedules of Investments provide additional information on the funds' portfolio holdings.

7. Risk Factors

The value of the funds’ shares will go up and down, sometimes rapidly or unpredictably, based on the performance of the securities owned by the funds and other factors generally affecting the securities market. Market risks, including political, regulatory, economic and social developments, can affect the value of the funds’ 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.

There are certain risks involved in investing in foreign securities. These risks include those resulting from 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. Securities of foreign issuers may be less liquid and more volatile. Investing a significant portion of assets in one country or region may accentuate these risks.

8. Federal Tax Information

The tax character of distributions paid during the years ended August 31, 2023 and August 31, 2022 were as follows:
2023 2022
Distributions Paid From: Distributions Paid From:
Ordinary
Income
Long-term
Capital Gains
Ordinary
Income
Long-term
Capital Gains
Focused Dynamic Growth ETF
Focused Large Cap Value ETF $ 5,093,109 $ 5,924,440 $ 9,198,604 $ 517,559

The book-basis character of distributions made during the year from net investment income or net realized gains may differ from their ultimate characterization for federal income tax purposes. These differences reflect the differing character of certain income items and net realized gains and losses for financial statement and tax purposes, and may result in reclassification among certain capital accounts on the financial statements.

The reclassifications for Focused Dynamic Growth ETF and Focused Large Cap Value ETF, which are primarily due to in kind transactions, were made to capital paid in $970,542 and $5,380,997 and distributable earnings (loss) $(970,542) and $(5,380,997), respectively.


20


As of period end, the federal tax cost of investments and the components of distributable earnings on a tax-basis were as follows:
Focused Dynamic Growth ETF Focused Large Cap Value ETF
Federal tax cost of investments $ 154,541,569  $ 201,455,704 
Gross tax appreciation of investments $ 34,452,586  $ 25,537,574 
Gross tax depreciation of investments (8,882,123) (7,451,900)
Net tax appreciation (depreciation) of investments $ 25,570,463  $ 18,085,674 
Undistributed ordinary income —  $ 1,070,849 
Accumulated short-term capital losses $ (11,806,850) — 
Accumulated long-term capital losses $ (12,670,199) — 
Late-year ordinary loss deferral $ (89,505) — 
Post-October capital loss deferral —  $ (987,314)

The difference between book-basis and tax-basis unrealized appreciation (depreciation) is attributable primarily to the tax deferral of losses on wash sales.

Accumulated capital losses represent net capital loss carryovers that may be used to offset future realized capital gains for federal income tax purposes. The capital loss carryovers may be carried forward for an unlimited period. Future capital loss carryover utilization in any given year may be subject to Internal Revenue Code limitations.

Loss deferrals represent certain qualified losses that the funds have elected to treat as having been incurred in the following fiscal year for federal income tax purposes.

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Trustees of American Century ETF Trust

Opinion on the Financial Statements and Financial Highlights

We have audited the accompanying statements of assets and liabilities, including the schedules of investments, of American Century Focused Dynamic Growth ETF and American Century Focused Large Cap Value ETF (the “Funds”), two of the funds constituting the American Century ETF Trust, as of August 31, 2023, the related statements of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the three years in the period then ended and from March 31, 2020 (fund inception) through August 31, 2020, and the related notes. In our opinion, the financial statements and financial highlights present fairly, in all material respects, the financial position of each of the Funds as of August 31, 2023, and the results of their operations for the year then ended, the changes in their net assets for each of the two years in the period then ended, and the financial highlights for each of the three years in the period then ended and from March 31, 2020 (fund inception) through August 31, 2020, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements and financial highlights are the responsibility of the Funds’ management. Our responsibility is to express an opinion on the Funds’ financial statements and financial highlights based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Funds in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement, whether due to error or fraud. The Funds are not required to have, nor were we engaged to perform, an audit of their internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Funds’ internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements and financial highlights, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements and financial highlights. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements and financial highlights. Our procedures included confirmation of securities owned as of August 31, 2023, by correspondence with the custodian and brokers; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

Management

The Board of Trustees
The individuals listed below serve as trustees of the funds. Each trustee will continue to serve in this capacity until death, retirement, resignation or removal from office. The board has adopted a mandatory retirement age for trustees who are not “interested persons,” as that term is defined in the Investment Company Act (independent trustees). Trustees who are not also officers of the trust shall retire on December 31st of the year in which they reach their 75th birthday.
Jonathan S. Thomas is an “interested person” because he currently serves as President and Chief Executive Officer of American Century Companies, Inc. (ACC), the parent company of American Century Investment Management, Inc. (ACIM or the advisor). The other trustees are independent. They are not employees, directors or officers of, and have no financial interest in, ACC or any of its wholly owned, direct or indirect, subsidiaries, including ACIM and American Century Services, LLC (ACS), and they do not have any other affiliations, positions or relationships that would cause them to be considered “interested persons” under the Investment Company Act. The following trustees also serve in this capacity for a number of other registered investment companies in the American Century Investments family of funds: Jonathan S. Thomas, 15; Jeremy I. Bulow, 8; and Stephen E. Yates, 7.

Approval of Management Agreement

At a meeting held on June 21, 2023, the Funds’ Board of Trustees (the "Board") unanimously approved the renewal of the management agreement pursuant to which American Century Investment Management, Inc. (the “Advisor”) acts as the investment advisor for each of the Funds. Under the Investment Company Act of 1940 (the “Investment Company Act”), contracts for investment advisory services are required to be reviewed, evaluated, and approved by a majority of a fund’s Trustees, including a majority of the independent Trustees.

Prior to its consideration of the management agreement renewal, the Trustees requested and reviewed extensive data and information compiled by the Advisor and certain independent data providers concerning the Funds. This review was in addition to the oversight and evaluation undertaken by the Board and its Audit Committee on a continual basis and the information received was supplemental to the extensive information that the Board and its Audit Committee receive and consider over time.

In connection with its consideration of the management agreement renewal, the Board’s review and evaluation of the services provided by the Advisor included, but was not limited to

the nature, extent, and quality of investment management, shareholder services, distribution services, and other services provided to the Funds;
the wide range of programs and services the Advisor and other service providers provide to the Funds and their shareholders on a routine and non-routine basis;
the Funds’ investment performance compared to appropriate benchmarks and/or peer groups of other funds with similar investment objectives and strategies;
the cost of owning the Funds compared to the cost of owning similarly-managed funds;
the Advisor’s compliance policies, procedures, and regulatory experience and those of certain other service providers;
the Advisor’s strategic plans, generally, and with respect to areas of heightened regulatory interest in the mutual fund industry and certain recent geopolitical and other issues;
the Advisor’s business continuity plans, vendor management practices, and information security practices;
the cost of services provided to the Funds, the profitability of the Funds to the Advisor, and the Advisor’s financial results of operation;
possible economies of scale associated with the Advisor’s management of the Funds;
any collateral benefits derived by the Advisor from the management of the Funds;
fees and expenses associated with any investment by the Funds in other funds;
payments to intermediaries by the Funds and the Advisor and services provided by intermediaries in connection therewith; and
services provided and charges to the Advisor’s other investment management clients.

The independent Trustees met separately in private sessions to discuss the renewal and to review and discuss the information provided in response to their request. The independent Trustees also held active discussions with the Advisor regarding the renewal of the management agreement. The independent Trustees had the benefit of the advice of their independent counsel throughout the process.

Factors Considered

The Trustees considered all of the information provided by the Advisor, the independent data providers, and independent counsel in connection with the approval. They determined that the information was sufficient for them to evaluate the management agreement for the Funds. In connection with their review, the Trustees did not identify any single factor as being all-important or controlling, and each Trustee may have attributed different levels of importance to different factors.
27


In deciding to renew the management agreement, the Board based its decision on a number of factors, including without limitation the following:

Nature, Extent and Quality of Services — Generally. Under each Fund’s management agreement, the Advisor is responsible for providing or arranging for all services necessary for the operation of each Fund. The Board noted that the Advisor provides or arranges at its own expense a wide variety of services which include the following:

constructing and designing each Fund
portfolio research and security selection
initial capitalization/funding
securities trading
Fund administration
custody of Fund assets
daily valuation of each Fund’s portfolio
liquidity monitoring and management
risk management, including information security
shareholder servicing and transfer agency, including shareholder confirmations, recordkeeping, and communications
legal services (except the independent Trustees’ counsel)
regulatory and portfolio compliance
financial reporting
marketing and distribution (except amounts paid by each Fund under Rule 12b-1 plans)

Investment Management Services. The nature of the investment management services provided to the Funds is quite complex and allows Fund shareholders access to professional money management, instant diversification of their investments, and liquidity. In evaluating investment performance, the Board expects the Advisor to manage each Fund in accordance with its investment objectives and principal investment strategies. Further, the Trustees recognize that the Advisor has an obligation to monitor trading activities, and in particular to seek the best execution of fund trades, and to evaluate the use of and payment for research. In providing these services, the Advisor utilizes teams of investment professionals who require extensive information technology, research, training, compliance, and other systems to conduct their business. The Board provides oversight of the investment performance process. It regularly reviews investment performance information for each Fund, together with comparative information for appropriate benchmarks over different time horizons. The Trustees also review investment performance information during the management agreement renewal process. If performance concerns are identified, the Board discusses with the Advisor the reasons for such results and any actions being taken to improve performance. The performance for American Century Focused Large Cap Value ETF was above its benchmark for the one-year period reviewed by the Board. The performance for American Century Focused Dynamic Growth ETF was below its benchmark for the one-year period reviewed by the Board. The Board found the investment management services provided by the Advisor to each Fund to be satisfactory and consistent with the management agreement.

Shareholder and Other Services. Under the management agreement, the Advisor provides or arranges for a comprehensive package of services to the Funds. The Board, directly and through its Audit Committee, regularly reviews reports and evaluations of such services at its regular meetings. These reports include, but are not limited to, information regarding the operational efficiency and accuracy of the shareholder and transfer agency services provided, staffing levels, shareholder satisfaction, technology support (including information security), new products and services offered to Fund shareholders, securities trading activities, portfolio valuation services, auditing services, and legal and operational compliance activities. The Board found the services provided by the Advisor to each Fund under the management agreement to be competitive and of high quality.

Costs of Services and Profitability. The Advisor provides detailed information concerning its cost of providing various services to the Funds, its profitability in managing each Fund (pre- and
28


post-distribution), and its financial results of operation. The Trustees have reviewed with the Advisor the methodology used to prepare this financial information. This information is considered in evaluating the Advisor’s financial condition, its ability to continue to provide services under the management agreement, and the reasonableness of the terms of the current management agreement. The Board concluded that the Advisor’s profits were reasonable in light of the services provided to the Funds.

Ethics. The Board generally considers the Advisor’s commitment to providing quality services to the Funds and to conducting its business ethically. They noted that the Advisor’s practices generally meet or exceed industry best practices.

Economies of Scale. The Board also reviewed information provided by the Advisor regarding the possible existence of economies of scale in connection with the management of each Fund. The Board concluded that economies of scale are difficult to measure and predict with precision, especially on a fund-by-fund basis. The Board concluded that the Advisor is sharing economies of scale, to the extent they exist, through its fee structure and through reinvestment in its business, infrastructure, investment capabilities and initiatives to provide shareholders additional content and services.

Comparison to Other Funds’ Fees. The management agreement provides that each Fund pays the Advisor a single, all-inclusive (or unified) management fee for providing all services necessary for the management and operation of the Fund, other than brokerage and other transaction fees and expenses relating to acquisition and disposition of portfolio securities, acquired fund fees and expenses, taxes, interest, extraordinary expenses, fund litigation expenses, expenses incurred in connection with the provision of shareholder services and distribution services under a plan adopted pursuant to Investment Company Act Rule 12b-1, and, for certain funds, fees and expenses of the Fund’s independent Trustees (including their independent legal counsel). Under the unified fee structure, the Advisor is responsible for providing investment advisory, custody, audit, administrative, compliance, recordkeeping, marketing and shareholder services, or arranging and supervising third parties to provide such services. The Board believes the unified fee structure is a benefit to Fund shareholders because it clearly discloses to shareholders the cost of owning Fund shares, and, since the unified fee cannot be increased without a vote of Fund shareholders, it shifts to the Advisor the risk of increased costs of operating the Fund and provides a direct incentive to minimize administrative inefficiencies. Part of the Board’s analysis of fee levels involves reviewing certain evaluative data compiled by an independent provider comparing the Fund’s unified fee to the total expense ratios of its peers. The unified fee charged to shareholders of American Century Focused Dynamic Growth ETF and American Century Focused Large Cap Value ETF was below the median of the total expense ratios of each Fund’s peer expense universe and was within the range of its peer expense group. The Board concluded that the management fee paid by each Fund to the Advisor under its management agreement is reasonable in light of the services provided to the Fund.

Comparison to Fees and Services Provided to Other Clients of the Advisor. The Board also requested and received information from the Advisor concerning the nature of the services, fees, costs, and profitability of its advisory services to funds or other advisory clients managed similarly to the Funds. They observed that these varying types of client accounts require different services and involve different regulatory and entrepreneurial risks than the management of the Funds. The Board analyzed this information and concluded that the fees charged and services provided to the Funds were reasonable by comparison.

Payments to Intermediaries. The Trustees also requested and received a description of payments made to intermediaries by each Fund and the Advisor and services provided in response thereto. These payments could include various payments made by each Fund or the Advisor to different types of intermediaries and recordkeepers for distribution and service activities provided for each Fund. The Trustees reviewed such information and received representations from the Advisor that all such payments by the Advisor were made from the Advisor’s resources and reasonable profits.
29



Collateral or “Fall-Out” Benefits Derived by the Advisor. The Board considered the possible existence of collateral benefits the Advisor may receive as a result of its relationship with the Funds. They concluded that the Advisor’s primary business is managing funds and it generally does not use fund or shareholder information to generate profits in other lines of business, and therefore does not derive any significant collateral benefits from them. The Board noted that additional assets from other clients may offer the Advisor some benefit from increased leverage with prospective clients, service providers, and counterparties. The Board also determined that the Advisor is able to provide investment management services to certain clients other than the Funds, at least in part, due to its existing infrastructure built to serve the fund complex. The Board concluded that appropriate allocation methodologies had been employed to assign resources and the cost of those resources to these other clients.

Existing Relationship. The Board also considered whether there was any reason for not continuing the existing arrangement with the Advisor. In this regard, the Board was mindful of the potential disruptions of the Funds’ operations and various risks, uncertainties, and other effects that could occur as a result of a decision not to continue such relationship. In particular, the Board recognized that most shareholders have invested in each Fund on the strength of the Advisor’s industry standing and reputation and in the expectation that the Advisor will have a continuing role in providing advisory services to each Fund.

Conclusion of the Trustees. As a result of this process, the Board, including all of the independent Trustees, taking into account all of the factors discussed above and the information provided by the Advisor and others in connection with its review and received over time, determined that the terms of the management agreement are fair and reasonable and that the management fee charged to each Fund is fair in light of the services provided and that the investment management agreement between each Fund and the Advisor should be renewed for an additional one-year period.

Liquidity Risk Management Program

The Funds have adopted a liquidity risk management program (the “program”). The Funds' Board of Trustees (the "Board") has designated American Century Investment Management, Inc. (“ACIM”) as the administrator of the program. Personnel of ACIM or its affiliates, including members of ACIM’s Investment Oversight Committee who are members of ACIM’s Investment Management and Global Analytics departments, conduct the day-to-day operation of the program pursuant to the program.

Under the program, ACIM manages the Funds' liquidity risk, which is the risk that the Funds could not meet shareholder redemption requests without significant dilution of remaining shareholders’ interests in the Funds. This risk is managed by monitoring the degree of liquidity of the Funds' investments, limiting the amount of the Funds' illiquid investments, and utilizing various risk management tools and facilities available to the Funds for meeting shareholder redemptions, among other means. ACIM’s process of determining the degree of liquidity of certain investments held by the Funds are supported by a third-party liquidity assessment vendor.

The Board reviewed a report prepared by ACIM regarding the operation and effectiveness of the program for the period January 1, 2022 through December 31, 2022. No significant liquidity events impacting the Funds were noted in the report. In addition, ACIM provided its assessment that the program had been effective in managing the Funds' liquidity risk.

Additional Information
 
Retirement Account Information
 
As required by law, distributions you receive from certain retirement accounts are subject to federal income tax withholding at the IRS default rate of 10%.* Tax will be withheld on the total amount withdrawn even though you may be receiving amounts that are not subject to withholding, such as nondeductible contributions. In such case, excess amounts of withholding could occur. You may adjust your withholding election so that a greater or lesser amount will be withheld.
Remember, even if you elect not to have income tax withheld, you are liable for paying income tax on the taxable portion of your withdrawal. If you elect not to have income tax withheld or you don’t have enough income tax withheld, you may be responsible for payment of estimated tax. You may incur penalties under the estimated tax rules if your withholding and estimated tax payments are not sufficient. You can reduce or defer the income tax on a distribution by directly or indirectly rolling such distribution over to another IRA or eligible plan. You should consult your tax advisor for additional information.
State tax will be withheld according to state regulations if, at the time of your distribution, your tax residency is within one of the mandatory withholding states.
*Some 403(b), 457 and qualified retirement plan distributions may be subject to 20% mandatory withholding, as they are subject to special tax and withholding rules.  Your plan administrator or plan sponsor is required to provide you with a special tax notice explaining those rules at the time you request a distribution.  If applicable, federal and/or state taxes may be withheld from your distribution amount.
