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: Yulin Long, Stephen Quance and Rene Casis

During the period, Steve Rossi left the fund’s management team, while Yulin Long and Stephen Quance joined.

Performance Review

American Century Low Volatility ETF returned 11.96% on both a market price and net asset value (NAV) basis for the 12-month period ended August 31, 2023. For the same period, the S&P 500 Index, the fund’s benchmark index, returned 15.94%. The fund’s NAV and market price returns reflect fees and operating expenses, while the index return does not.

Following a tumultuous 2022 and early 2023, the markets embraced a Goldilocks scenario. U.S. economic strength surprised to the upside, albeit on lowered expectations, and inflation moderated. Some economists abandoned their recession calls in favor of soft landing expectations.

Despite weaker fundamentals, broad equity indices delivered strong gains for the reporting period. Larger-capitalization technology companies rose significantly, particularly those perceived to benefit from the artificial intelligence theme. Other sectors and smaller-capitalization companies did not advance as much. Markets remained resilient even after several regional banks shuttered in March and early April. Quick government intervention staved off a broader market contagion. Nevertheless, many viewed the bank crisis as an impetus for the Federal Reserve to end its rate-hike campaign. This prompted equity markets to rally through July, when stocks declined amid worries about rates remaining higher for longer than expected.

Low-Volatility Focus Weighed on Relative Performance

The fund’s focus on lower-volatility equities in a period of strong stock gains largely explain the fund’s underperformance. Such strategies have historically done well relative to the broader market when stocks fall, but lag when stocks rally. Large-capitalization growth stocks performed best in the reporting period followed by select economically sensitive sectors; more defensive market segments lagged.

For example, within the index, information technology, communication services and the cyclical industrials sectors were the only sectors to outperform the broader index. Meanwhile, more defensive sectors, such as utilities and real estate declined outright, while consumer staples rose but significantly underperformed the overall index.

Positioning within the information technology sector detracted most from performance on a relative basis, particularly among semiconductors and semiconductor equipment companies. These stocks benefited from investor demand for companies related to artificial intelligence. Elsewhere in the sector, selection and allocation decisions among software and computers and peripherals companies detracted from relative results. Positioning in the industrials sector also detracted, led by our holdings among machinery and commercial services and supplies companies.

At the other end of the spectrum, our stock selection and allocation decisions contributed the most to relative performance in the consumer discretionary sector. It helped to avoid the volatile automobiles industry. Positioning in the broadline retail and hotels, restaurants and leisure industries also contributed to performance. Stock selection among chemicals companies also was positive, making materials stocks another source of relative strength.

Portfolio Commentary

Portfolio Managers: Rene Casis and Hitesh Patel

Performance Review

American Century Quality Convertible Securities ETF returned 2.46% on a market price basis for the 12-month period ended August 31, 2023. On a net asset value (NAV) basis, the fund returned 2.56%. For the same period, the ICE BofA Convertible Index, the fund’s benchmark index, returned 3.77%. The fund’s NAV and market price returns reflect fees and operating expenses, while the index return does not.

Following a tumultuous 2022 and early 2023, the markets embraced a Goldilocks scenario. U.S. economic strength surprised to the upside, albeit on lowered expectations, and inflation moderated. Some economists abandoned their recession calls in favor of soft landing expectations.

Despite weaker fundamentals, broad equity indices delivered strong gains for the reporting period. Larger-capitalization technology companies rose significantly, particularly those perceived to benefit from the artificial intelligence theme. Other sectors and smaller-capitalization companies did not advance as much. Markets remained resilient even after several regional banks shuttered in March and early April. Quick government intervention staved off a broader market contagion. Nevertheless, many viewed the bank crisis as an impetus for the Federal Reserve (Fed) to end its rate-hike campaign. This prompted yields to decline and equity markets to rally. But the Fed continued to tighten, and yields resumed their upward march through period-end.

Additionally, stronger-than-expected second-quarter earnings further supported equity gains. Credit spreads remained at very tight levels even as default expectations rose.

Defensive Positioning, Quality Focus Weighed on Relative Performance

The fund's cautious positioning primarily drove the fund’s underperformance. In the face of aggressively tighter monetary policy, we expected deteriorating economic fundamentals and lower corporate earnings. Accordingly, we favored a more defensive posture. However, upside surprises in growth and moderating inflation fueled a rally among risk assets. Generally, growth outperformed value factors for the reporting period, and cyclical sectors performed better than defensive sectors.

For example, within the index, more defensive sectors, such as utilities and consumer staples, underperformed the overall index results. We held overweight positions versus the index in those sectors.

The consumer discretionary and technology sectors led the index’s positive performance, as expectations for more moderate Fed tightening propelled their underlying equity prices higher. Unprofitable technology companies, many of which the fund did not own, rallied sharply as investors began to expect the Fed to pause its rate-hike cycle. While many low-quality companies posted outsized market gains, the fund did benefit from security selection in the technology sector. Certain software, cybersecurity and IT services companies advanced during periods when the market focused on valuations and rewarded more stable cash flow-generating businesses.

The fund's underweight positions in consumer discretionary companies with more cyclical earnings also weighed on relative results. These companies, including cruise lines, specialty retailers and real estate firms, rallied on stronger-than-expected consumer spending.

Portfolio Commentary

Portfolio Managers: Rene Casis and Will Enderle

Paul Jo no longer serves as a portfolio manager for the American Century Quality Diversified International ETF.

Performance Review

For the 12 months ended August 31, 2023, American Century Quality Diversified International ETF returned 18.78% on a market price basis. On a net asset value (NAV) basis, the fund returned 18.67%.

Non-U.S. equities, as measured by the MSCI World ex USA Index (world index), rose during the reporting period. The world index, which is an unmanaged index generally representative of the performance of large- and mid-capitalization non-U.S. equities, returned 16.45%. The fund’s outperformance versus the world index was largely due to the different compositions of the fund and the world index.

Relatively consistent outperformance of value stocks versus growth in non-U.S. developed markets helped the fund’s performance. Inflation cooled in many regions with aggressive interest rate hiking by central banks. Value stocks continued to benefit as investors remained cautious of a global economic slowdown, and the fund’s dynamic allocation was positioned in favor of value for much of the period.

From a sector perspective, financials and utilities gave the largest boost to performance versus the world index, while real estate and consumer discretionary also contributed. Conversely, materials and information technology holdings were the largest detractors from the fund’s relative performance followed by holdings in the industrials sector.

Within financials, rising interest rates in many of the world’s economies were a positive development for the banking industry, and the fund benefited from positioning within the group by holding some of the stronger-performing banks and avoiding key underperforming names in the world index. It was a similar story among insurers, as portfolio positioning within that industry also supported relative returns. Within the utilities sector, it was providers of electric and multi-utilities which contributed most notably. The portfolio’s underweighting of real estate companies compared to the world index helped its relative performance as rising interest rates were a headwind for the sector during the period. Within the consumer discretionary sector, it was holdings in automobiles manufacturers, which gave the biggest lift to relative returns. The most notable name in the group was performance automaker, Ferrari NV.

On the downside, holdings in the metals and mining industry weighed on returns as inflation cooled in many of the world’s economies during the period, posing a more challenging environment for the group. Within the information technology sector, positions in semiconductors and semiconductor equipment companies detracted most from the fund’s relative performance versus the world index.

Portfolio Commentary

Portfolio Managers: Rene Casis and Hitesh Patel

Performance Review

American Century Quality Preferred ETF returned 2.62% on a market price basis for the 12-month period ended August 31, 2023. On a net asset value (NAV) basis, the fund returned 2.96%. For the same period, the ICE Exchange-Listed Preferred & Hybrid Securities Index, the fund’s benchmark, returned -0.52%. The fund’s NAV and market price returns reflect fees and operating expenses, while the index return does not.

While equities staged an impressive rally over the 12-month period, preferred securities failed to keep pace. Higher bond yields and banking industry weakness weighed heavily on preferred securities. During this period, investors generally favored $1,000 par value institutional preferred securities over $25 par value exchange-listed preferreds. Securities with variable coupons outperformed fixed-rate securities amid higher rates.

Defensive Positioning, Duration Management, Security Selection Aided Performance

Overall, the fund’s defensive posture, shorter duration versus the index and security selection accounted for the fund’s outperformance versus the index. Against the backdrop of slowing growth and high inflation, the fund’s focus on quality issuers was a strong contributor to relative performance.

The fund’s short duration versus the index contributed to relative performance as the two-year Treasury yield rose 1.4 percentage points over the reporting period.

Security selection, notably in the financials sector, also lifted relative performance during the fiscal year. Due to our cautious market outlook, the fund was allocated to less-cyclical industries within financials and emphasized large, diversified banks over small regional lenders. This strategy helped the fund avoid large drawdowns early in 2023, when smaller banks faced a liquidity crunch.

Portfolio Commentary

Portfolio Managers: Rene Casis and Will Enderle

Portfolio manager Paul Jo left the investment team in April 2023, and portfolio manager Peruvemba Satish left the team in May 2023.

Performance Review

American Century U.S. Quality Growth ETF returned 16.95% on a market price basis for the 12 months ended August 31, 2023. On a net asset value (NAV) basis, the fund returned 16.96%.

For the same time period, the fund lagged market-capitalization-weighted growth strategies, as measured by the Russell 1000 Growth Index (growth index). The growth index is an unmanaged index generally representative of the performance of U.S. large-capitalization growth stocks. The fund’s underperformance versus the growth index was largely due to the different compositions of the fund and the growth index. The fund’s returns also reflect fees and operating expenses, while the index return does not.

From a broad perspective, stock selection in the information technology sector helped drive underperformance versus the growth index. Within information technology, stock selection among semiconductors and semiconductor equipment companies detracted, although an overweight allocation to the industry mitigated some of that weakness. On the positive side, an underweight allocation to consumer staples was beneficial, as was stock selection in the sector.

The fund’s allocation closed the fiscal year with a 65% weight in stable growth and 35% weight in high growth. Allocations are rebalanced monthly, based on a strategy informed by recent risk-adjusted performance.

Portfolio Commentary

Portfolio Managers: Rene Casis and Will Enderle

Portfolio manager Paul Jo left the investment team in April 2023, and portfolio manager Peruvemba Satish left the team in May 2023.

Performance Review

American Century U.S. Quality Value ETF returned 10.37% on a market price basis for the 12-month period ended August 31, 2023. On a net asset value (NAV) basis, the fund returned 10.40%.

For the same time period, the Russell 1000 Value Index (value index), a market-capitalization index, returned 8.59%. The value index is an unmanaged index generally representative of the performance of U.S. large-capitalization value stocks. The fund’s performance versus the value index was largely attributable to the different compositions of the fund and the value index. The fund’s returns also reflect fees and operating expenses, while the index return does not.

From a broad perspective, the fund’s stock selection in the health care sector helped drive outperformance relative to the value index, especially in the health care providers and services industry. Utilities also benefited performance through an underweight allocation versus the index and stock choices. Stock selection in consumer staples and an overweight allocation to the sector detracted from relative performance.

The fund’s allocation closed the 12-month period with an 80% allocation to value and a 20% allocation to income. Over the course of the year, the allocation to value was as high as 80% and as low as 35%. Allocations are rebalanced monthly, based on a strategy informed by recent risk-adjusted performance.

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.

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 Low Volatility ETF (Low Volatility ETF), American Century Quality Convertible Securities ETF (Quality Convertible Securities ETF), American Century Quality Diversified International ETF (Quality Diversified International ETF), American Century Quality Preferred ETF (Quality Preferred ETF), American Century U.S. Quality Growth ETF (formerly American Century STOXX® U.S. Quality Growth ETF) (U.S. Quality Growth ETF) and American Century U.S. Quality Value ETF (formerly American Century STOXX® U.S. Quality Value ETF) (U.S. Quality Value ETF) are six funds in a series issued by the trust.

Quality Diversified International ETF, U.S. Quality Growth ETF and U.S. Quality Value ETF's investment objectives are to seek to provide investment results that closely correspond, before fees and expenses, to the performance of each fund's underlying index. Shares of Low Volatility ETF, Quality Diversified International ETF, U.S. Quality Growth ETF and U.S. Quality Value ETF are listed for trading on the NYSE Arca, Inc. Shares of Quality Convertible Securities ETF and Quality Preferred ETF 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. Equity securities initially expressed in local currencies are translated into U.S. dollars at the mean of the appropriate currency exchange rate at the close of the NYSE as provided by an independent pricing service.

Fixed income securities are valued at the evaluated mean as provided by independent pricing services or at the mean of the most recent bid and asked prices as provided by investment dealers. Corporate bonds and convertible bonds are valued using market models that consider trade data, quotations from dealers and active market makers, relevant yield curve and spread data, creditworthiness, trade data or market information on comparable securities, and other relevant security specific information.

Hybrid securities are valued at the evaluated mean as provided by independent pricing services or at the mean of the most recent bid and asked prices as provided by investment dealers. Preferred stocks and convertible preferred stocks with perpetual maturities are valued using market models that consider trade data, quotations from dealers and active market makers, relevant yield curve and spread data, creditworthiness, trade data or market information on comparable securities, and other relevant security specific information.
69


Open-end management investment companies are valued at the reported NAV per share. Exchange-traded futures contracts are valued at the settlement price as provided by the appropriate exchange.

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.

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. For convertible bonds, the premiums attributable only to the debt instrument are amortized. Securities lending income is net of fees and rebates earned by the lending agent for its services.

Foreign Currency Translations — All assets and liabilities initially expressed in foreign currencies are translated into U.S. dollars at prevailing exchange rates at period end. The funds may enter into spot foreign currency exchange contracts to facilitate transactions denominated in a foreign currency. Purchases and sales of investment securities, dividend and interest income, spot foreign currency exchange contracts, and expenses are translated at the rates of exchange prevailing on the respective dates of such transactions. Net realized and unrealized foreign currency exchange gains or losses related to investment securities are a component of net realized gain (loss) on investment transactions and change in net unrealized appreciation (depreciation) on investments, respectively.

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 monthly for Quality Convertible Securities ETF and Quality Preferred ETF. Distributions from net investment income, if any, are generally declared and paid quarterly for Low Volatility ETF, U.S. Quality Growth ETF and U.S. Quality Value ETF. Distributions from net investment income, if any, are generally declared and paid semiannually for Quality Diversified International ETF. Distributions from net realized gains, if any, are generally declared and paid annually for all funds. 

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.
70


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.

*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.

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.

The following is a summary of the level classifications as of period end. The Schedules of Investments provide additional information on the funds' portfolio holdings.

7. Derivative Instruments

Equity Price Risk — The funds are subject to equity price risk in the normal course of pursuing their investment objectives. A fund may enter into futures contracts based on an equity index in order to manage its exposure to changes in market conditions. A fund may purchase futures contracts to gain exposure to increases in market value or sell futures contracts to protect against a decline in market value. Upon entering into a futures contract, a fund is required to deposit either cash or securities in an amount equal to a certain percentage of the contract value (initial margin). A fund may incur charges or earn income on cash deposit balances, which are reflected in interest expenses or interest income, respectively. Subsequent payments (variation margin) are made or received daily, in cash, by a fund. The variation margin is equal to the daily change in the contract value and is recorded as unrealized gains and losses. A fund recognizes a realized gain or loss when the contract is closed or expires. Net realized and unrealized gains or losses occurring during the holding period of futures contracts are a component of net realized gain (loss) on futures contract transactions and change in net unrealized appreciation (depreciation) on futures contracts, respectively. One of the risks of entering into futures contracts is the possibility that the change in value of the contract may not correlate with the changes in value of the underlying securities.

The funds' average notional exposure to equity price risk derivative instruments held during the period were as follows:

8. 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.

The funds may invest in instruments that have variable or floating coupon rates based on the London Interbank Offered Rate (LIBOR). LIBOR is a benchmark interest rate intended to be representative of the rate at which certain major international banks lend to one another over short-terms. Financial institutions have started the process of phasing out LIBOR and the transition process to a replacement rate may lead to increased volatility or illiquidity in markets for instruments that rely on LIBOR. This could result in a change to the value of such instruments or a change in the cost of temporary borrowing for the fund.

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 in emerging markets or a significant portion of assets in one country or region may accentuate these risks.

75


Quality Diversified International ETF, U.S. Quality Growth ETF and U.S. Quality Value ETF are not actively managed and do not attempt to take defensive positions under any market conditions, including declining markets. Therefore, the funds generally will not buy or sell securities unless they are added or removed from their respective indexes, even if the security is underperforming. If the funds' respective indexes have high portfolio turnover, the funds may also have high portfolio turnover.

A fund's investment process may result in high portfolio turnover, which could mean high transaction costs, affecting both performance and capital gains tax liabilities to investors.

9. 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
Low Volatility ETF $ 128,357  —  $ 98,904  — 
Quality Convertible Securities ETF $ 618,718  —  $ 478,670  — 
Quality Diversified International ETF $ 7,274,680  —  $ 6,315,055  — 
Quality Preferred ETF $ 1,587,293  —  $ 961,361  — 
U.S. Quality Growth ETF $ 1,839,795  —  $ 911,250  — 
U.S. Quality Value ETF $ 5,272,570  —  $ 4,592,625  — 

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, which are primarily due to in kind transactions, were as follows:
Low Volatility ETF Quality Convertible
Securities ETF
Quality Diversified

Accumulated long-term capital losses $ (954,241) $ (7,585,177) $ (6,693,951)

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

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.

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.

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.
88


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 Low Volatility ETF, American Century Quality Convertible Securities ETF, and American Century Quality Preferred ETF was above each Fund’s respective benchmark for the one-year period reviewed by the Board. The performance for American Century Quality Diversified International ETF, American Century U.S. Quality Growth ETF, and American Century U.S. Quality Value ETF was below each Fund ’s respective benchmark for the one- and three-year periods 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.
89



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 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 Low Volatility ETF, American Century Quality Diversified International ETF, American Century U.S. Quality Growth ETF, and American Century U.S. Quality 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 unified fee charged to shareholders of American Century Low Volatility ETF, American Century Quality Diversified International ETF, American Century U.S. Quality Growth ETF, and American Century U.S. Quality 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 unified fee charged to shareholders of American Century Quality Convertible Securities ETF and American Century Quality Preferred ETF was the lowest of the total expense ratios of each Fund's respective peer expense universe and 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
90


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.

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.

91


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.

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.
