President’s Letter

Jonathan Thomas

Dear Investor:

Thank you for reviewing this annual report for the period ended March 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.

Challenging Conditions Weighed on Asset Class Returns

Prevailing headwinds early in the reporting period continued to challenge U.S. financial markets throughout the 12 months. Asset class performance seesawed but declined overall amid mixed economic data, elevated inflation and anticipated monetary policy responses. By period-end, a new headwind emerged: banking industry uncertainty.

After launching its inflation-fighting rate-hike campaign in March 2022, the Federal Reserve (Fed) lifted rates eight more times by period-end. The federal funds target rate ended the reporting period at 4.75% to 5%, its highest level since 2007, while Treasury yields climbed to multiyear highs. Amid the Fed’s efforts, the annual inflation rate peaked at 9.1% in June, a 40-year high, before easing to 5% by March.

In addition to helping tame inflation, rapidly rising rates also fueled recession worries and led to expectations for the Fed to change course. This sentiment helped spark a rebound among stock and bond indices in the second half of the reporting period. The collapse of two U.S. regional banks late in the period and fears of a looming credit crunch and likely recession also contributed to market expectations for a Fed policy change. Nevertheless, the Fed indicated a near-term course change was unlikely.

Despite delivering strong gains in the second half of the reporting period, stock returns succumbed to first-half losses and declined for the 12 months. Similarly, weakness in the first half of the period overwhelmed second-half gains, and bond returns were negative for the 12-month period.

Remaining Diligent in Uncertain Times

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

We appreciate your confidence in us during these extraordinary times. Our firm 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,

Jonathan Thomas

President and Chief Executive Officer

American Century Investments

Average annual returns since inception are presented when ten years of performance history is not available. Fund returns would have been lower if a portion of the fees had not been waived.

C Class shares will automatically convert to A Class shares after being held for approximately eight years. C Class average annual returns do not reflect this conversion.

Sales charges include initial sales charges and contingent deferred sales charges (CDSCs), as applicable. A Class shares have a 4.50% maximum initial sales charge and may be subject to a maximum CDSC of 1.00%. C Class shares redeemed within 12 months of purchase are subject to a maximum CDSC of 1.00%. The SEC requires that mutual funds provide performance information net of maximum sales charges in all cases where charges could be applied.

Data presented reflect past performance. Past performance is no guarantee of future results. Current performance may be higher or lower than the performance shown. Total returns for periods less than one year are not annualized. Investment return and principal value will fluctuate, and redemption value may be more or less than original cost. Data assumes reinvestment of dividends and capital gains, and none of the charts reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares.

Portfolio Commentary

Portfolio Managers: Bob Gahagan, Peter Van Gelderen, Jeff Houston, Jason Greenblath and Charles Tan

Performance Summary

Core Plus returned -6.42%* for the 12 months ended March 31, 2023. By comparison, the Bloomberg U.S. Aggregate Bond Index returned -4.78%. Fund returns reflect operating expenses, while index returns do not.

Inflation, Federal Reserve Policy Challenged Bond Market

Elevated inflation, aggressive Federal Reserve (Fed) policy, rising interest rates and mounting recession risk dominated the reporting period and contributed to heightened market volatility. After peaking in June, inflation moderated but remained well above the Fed’s target, which led to consistent interest rate hikes. In March, the collapse of two U.S. regional banks introduced a new market headwind, as banks moved to tighten lending standards amid industry uncertainty.

Against this backdrop, Treasury yields were volatile, particularly during the banking industry turmoil. For the period overall, yields rose sharply across the yield curve. This dynamic contributed to negative 12-month returns for most investment-grade bond market sectors, including Treasuries, mortgage-backed securities (MBS) and corporate bonds. Credit-sensitive and longer maturity securities generally posted the largest losses.

High-Yield Exposure Weighed on Relative Results

An out-of-index hedged position in high-yield securities detracted from relative performance. The hedge, which included high-yield credit default swaps and reflected our more-defensive strategy, detracted as high-yield securities advanced in the second half of the reporting period. We reduced the portfolio’s high-yield exposure by the end of March, as we adopted an up-in-quality bias.

Security Selection Detracted

Security selection weighed on relative results, largely due to the securitized sector and positions in non-agency collateralized mortgage obligations (CMOs) and collateralized loan obligations (CLOs). However, positive relative results from agency MBS and asset-backed securities helped offset some of the negative effects from CMOs and CLOs. Selections among investment-grade corporates and emerging markets debt also detracted.

Duration Hindered Relative Performance

We began gradually extending the portfolio’s duration in the second half of 2022, as short-maturity Treasury yields were climbing to multiyear highs. In our view, the combination of high inflation, rising Treasury yields and aggressive Fed tightening would eventually trigger a recession and push yields lower. However, yields rose overall, and our longer-than-index duration positioning suffered. The strategy did aid relative results late in the period when the bank failures sparked a flight to quality.

*All fund returns referenced in this commentary are for Investor Class shares. Performance for other share classes will vary due to differences in fee structure; when Investor Class performance exceeds that of the index, other share classes may not. See page 3 for returns for all share classes.

Shareholder Fee Example

Fund shareholders may incur two types of costs: (1) transaction costs, including sales charges (loads) on purchase payments and redemption/exchange fees; and (2) ongoing costs, including management fees; distribution and service (12b-1) 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 mutual 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 October 1, 2022 to March 31, 2023.

Actual Expenses

The table provides information about actual account values and actual expenses for each class. You may use the information, together with the amount you invested, to estimate the expenses that you paid over the period. First, identify the share class 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.

If you hold Investor Class shares of any American Century Investments mutual fund, or I Class shares of the American Century Diversified Bond Fund, in an American Century Investments account (i.e., not through a financial intermediary or employer-sponsored retirement plan account), American Century Investments may charge you a $25 annual account maintenance fee if the value of those shares is less than $10,000. We will redeem shares automatically in one of your accounts to pay the $25 fee. In determining your total eligible investment amount, we will include your investments in all personal accounts (including American Century Investments brokerage accounts) registered under your Social Security number. Personal accounts include individual accounts, joint accounts, UGMA/UTMA accounts, personal trusts, Coverdell Education Savings Accounts and IRAs (including traditional, Roth, Rollover, SEP-, SARSEP- and SIMPLE-IRAs), and certain other retirement accounts. If you have only business, business retirement, employer-sponsored or American Century Investments brokerage accounts, you are currently not subject to this fee. If you are subject to the account maintenance fee, your account value could be reduced by the fee amount.

Hypothetical Example for Comparison Purposes

The table also provides information about hypothetical account values and hypothetical expenses based on the actual expense ratio of each class of your fund and an assumed rate of return of 5% per year before expenses, which is not the actual return of a fund’s share class. 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 sales charges (loads) or redemption/exchange fees. 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.

G Class	$1,000	$1,024.88	$0.05	0.01%

(1)Expenses are equal to the class's annualized expense ratio listed in the table above, multiplied by the average account value over the period, multiplied by 182, the number of days in the most recent fiscal half-year, divided by 365, to reflect the one-half year period. 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

MARCH 31, 2023

1. Organization

American Century Investment Trust (the trust) is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company and is organized as a Massachusetts business trust. Core Plus Fund (the fund) is one fund in a series issued by the trust. The fund’s investment objective is to seek to maximize total return. As a secondary objective, the fund seeks a high level of income.

The fund offers the Investor Class, I Class, A Class, C Class, R Class, R5 Class and G Class. The A Class may incur an initial sales charge. The A Class and C Class may be subject to a contingent deferred sales charge.

2. Significant Accounting Policies

The following is a summary of significant accounting policies consistently followed by the fund in preparation of its financial statements. The 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.

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, U.S. Treasury and Government Agency securities, bank loan obligations, municipal securities and sovereign governments and agencies 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. Mortgage-related and asset-backed securities are valued based on models that consider trade data, prepayment and default projections, benchmark yield and spread data and estimated cash flows of each tranche of the issuer. Collateralized loan obligations are valued based on discounted cash flow models that consider trade and economic data, prepayment assumptions and default projections. Fixed income 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.

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.

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.

Open-end management investment companies are valued at the reported NAV per share. Repurchase agreements are valued at cost, which approximates fair value. Exchange-traded futures contracts are valued at the settlement price as provided by the appropriate exchange. Swap agreements are valued at an evaluated mean as provided by independent pricing services or independent brokers. Forward foreign currency exchange contracts are valued at the mean of the appropriate forward exchange rate at the close of the NYSE as provided by an independent pricing service. Investments 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.

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 fund 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 the 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 — Interest income less foreign taxes withheld, if any, is recorded on the accrual basis and includes paydown gain (loss) and accretion of discounts and amortization of premiums. Inflation adjustments related to inflation-linked debt securities are reflected as interest income.

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 fund 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.

Forward Commitments — The fund may engage in securities transactions on a forward commitment basis. In these transactions, the securities’ prices and yields are fixed on the date of the commitment. The fund may sell a to-be-announced (TBA) security and at the same time make a commitment to purchase the same security at a future date at a specified price. Conversely, the fund may purchase a TBA security and at the same time make a commitment to sell the same security at a future date at a specified price. These types of transactions are known as “TBA roll” transactions and are accounted for as purchases and sales. The fund will segregate cash, cash equivalents or other appropriate liquid securities on its records in amounts sufficient to meet the purchase price.

Repurchase Agreements — The fund may enter into repurchase agreements with institutions that ACIM has determined are creditworthy pursuant to criteria adopted by the Board of Trustees. The fund requires that the collateral, represented by securities, received in a repurchase transaction be transferred to the custodian in a manner sufficient to enable the fund to obtain those securities in the event of a default under the repurchase agreement. ACIM monitors, on a daily basis, the securities transferred to ensure the value, including accrued interest, of the securities under each repurchase agreement is equal to or greater than amounts owed to the fund under each repurchase agreement.

Joint Trading Account — Pursuant to an Exemptive Order issued by the Securities and Exchange Commission, the fund, along with certain other funds in the American Century Investments family of funds, may transfer uninvested cash balances into a joint trading account. These balances are invested in one or more repurchase agreements that are collateralized by U.S. Treasury or Agency obligations.

Income Tax Status — It is the 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 fund files U.S. federal, state, local and non-U.S. tax returns as applicable. The fund's 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.

Multiple Class — All shares of the fund represent an equal pro rata interest in the net assets of the class to which such shares belong, and have identical voting, dividend, liquidation and other rights and the same terms and conditions, except for class specific expenses and exclusive rights to vote on matters affecting only individual classes. Income, non-class specific expenses, and realized and unrealized capital gains and losses of the fund are allocated to each class of shares based on their relative net assets.

Distributions to Shareholders — Distributions from net investment income, if any, are declared daily and paid monthly. 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 fund. In addition, in the normal course of business, the fund enters 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.

3. Fees and Transactions with Related Parties

Management Fees — The trust has entered into a management agreement with ACIM, under which ACIM provides the fund with investment advisory and management services in exchange for a single, unified management fee (the fee) per class. The agreement provides that ACIM will pay all expenses of managing and operating the fund, except brokerage expenses, taxes, interest, fees and expenses of the independent trustees (including legal counsel fees), extraordinary expenses, and expenses incurred in connection with the provision of shareholder services and distribution services under a plan adopted pursuant to Rule 12b-1 under the 1940 Act. The fee is computed and accrued daily based on each class’s daily net assets and paid monthly in arrears. The difference in the fee among the classes is a result of their separate arrangements for non-Rule 12b-1 shareholder services. It is not the result of any difference in advisory or custodial fees or other expenses related to the management of the fund's assets, which do not vary by class. The fee consists of (1) an Investment Category Fee based on the daily net assets of the fund and certain other accounts managed by the investment advisor that are in the same broad investment category as the fund and (2) a Complex Fee based on the assets of all funds in the American Century Investments family of funds that have the same investment advisor and distributor as the fund. For purposes of determining the Investment Category Fee and Complex Fee, the assets of funds managed by the investment advisor that invest exclusively in the shares of other funds (funds of funds) are not included. The investment advisor agreed to waive the G Class's management fee in its entirety. The investment advisor expects this waiver to remain in effect permanently and cannot terminate it without the approval of the Board of Trustees.

The Investment Category Fee range, the Complex Fee range and the effective annual management fee for each class for the period ended March 31, 2023 are as follows:


	Investment Category Fee Range	Complex Fee Range	Effective Annual Management Fee
Investor Class	0.2425% to 0.3600%	0.2500% to 0.3100%	0.54%
I Class		0.1500% to 0.2100%	0.44%
A Class		0.2500% to 0.3100%	0.54%
C Class		0.2500% to 0.3100%	0.54%
R Class		0.2500% to 0.3100%	0.54%
R5 Class		0.0500% to 0.1100%	0.34%
G Class		0.0500% to 0.1100%	0.00%(1)

(1)Effective annual management fee before waiver was 0.34%.

Distribution and Service Fees — The Board of Trustees has adopted a separate Master Distribution and Individual Shareholder Services Plan for each of the A Class, C Class and R Class (collectively the plans), pursuant to Rule 12b-1 of the 1940 Act. The plans provide that the A Class will pay ACIS an annual distribution and service fee of 0.25%. The plans provide that the C Class will pay ACIS an annual distribution and service fee of 1.00%, of which 0.25% is paid for individual shareholder services and 0.75% is paid for distribution services. The plans provide that the R Class will pay ACIS an annual distribution and service fee of 0.50%. The fees are computed and accrued daily based on each class’s daily net assets and paid monthly in arrears. The fees are used to pay financial intermediaries for distribution and individual shareholder services. Fees incurred under the plans during the period ended March 31, 2023 are detailed in the Statement of Operations.

Trustees' Fees and Expenses — The Board of Trustees is responsible for overseeing the investment advisor’s management and operations of the fund. The trustees receive detailed information about the fund and its investment advisor regularly throughout the year, and meet at least quarterly with management of the investment advisor to review reports about fund operations. The fund's officers do not receive compensation from the fund.

Interfund Transactions — The fund 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. During the period, the interfund purchases were $1,596,000 and there were no interfund sales.

4. Investment Transactions

Purchases of investment securities, excluding short-term investments, for the period ended March 31, 2023 totaled $802,826,904, of which $622,379,182 represented U.S. Treasury and Government Agency obligations.

Sales of investment securities, excluding short-term investments, for the period ended March 31, 2023 totaled $866,405,841, of which $591,759,550 represented U.S. Treasury and Government Agency obligations.

6. Fair Value Measurements

The fund's investments valuation process is based on several considerations and may use multiple inputs to determine the fair value of the investments held by the fund. 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 Schedule of Investments provides additional information on the fund's portfolio holdings.

7. Derivative Instruments

Credit Risk — The fund is subject to credit risk in the normal course of pursuing its investment objectives. The value of a bond generally declines as the credit quality of its issuer declines. Credit default swap agreements enable a fund to buy/sell protection against a credit event of a specific issuer or index. A fund may attempt to enhance returns by selling protection or attempt to mitigate credit risk by buying protection. The buyer/seller of credit protection against a security or basket of securities may pay/receive an up-front or periodic payment to compensate for/against potential default events. Changes in value, including the periodic amounts of interest to be paid or received on swap agreements, are recorded as unrealized appreciation (depreciation) on swap agreements. Upon entering into a centrally cleared swap, a fund is required to deposit cash or securities (initial margin) with a financial intermediary in an amount equal to a certain percentage of the notional amount. 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 value and is a component of unrealized gains and losses. Realized gain or loss is recorded upon receipt or payment of a periodic settlement or termination of swap agreements. Net realized and unrealized gains or losses occurring during the holding period of swap agreements are a component of net realized gain (loss) on swap agreement transactions and change in net unrealized appreciation (depreciation) on swap agreements, respectively. The risks of entering into swap agreements include the possible lack of liquidity, failure of the counterparty to meet its obligations, and that there may be unfavorable changes in the underlying investments or instruments. The fund's average notional amount held during the period was $25,234,750.

Foreign Currency Risk — The fund is subject to foreign currency exchange rate risk in the normal course of pursuing its investment objectives. The value of foreign investments held by a fund may be significantly affected by changes in foreign currency exchange rates. The dollar value of a foreign security generally decreases when the value of the dollar rises against the foreign currency in which the security is denominated and tends to increase when the value of the dollar declines against such foreign currency. A fund may enter into forward foreign currency exchange contracts to reduce a fund's exposure to foreign currency exchange rate fluctuations or to gain exposure to the fluctuations in the value of foreign currencies. A fund will segregate cash, cash equivalents or other appropriate liquid securities on its records in amounts sufficient to meet requirements. The net U.S. dollar value of foreign currency underlying all contractual commitments held by a fund and the resulting unrealized appreciation or depreciation are determined daily. Realized gain or loss is recorded upon settlement of the contract. Net realized and unrealized gains or losses occurring during the holding period of forward foreign currency exchange contracts are a component of net realized gain (loss) on forward foreign currency exchange contract transactions and change in net unrealized appreciation (depreciation) on forward foreign currency exchange contracts, respectively. A fund bears the risk of an unfavorable change in the foreign currency exchange rate underlying the forward contract. Additionally, losses, up to the fair value, may arise if the counterparties do not perform under the contract terms. The fund's average U.S. dollar exposure to foreign currency risk derivative instruments held during the period was $3,962,518.

Interest Rate Risk — The fund is subject to interest rate risk in the normal course of pursuing its investment objectives. The value of bonds generally declines as interest rates rise. A fund may enter into futures contracts based on a bond index or a specific underlying security. 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 will segregate cash, cash equivalents or other appropriate liquid securities on its records in amounts sufficient to meet requirements. 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 futures 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 fund's average notional exposure to interest rate risk derivative instruments held during the period was $57,554,014 futures contracts purchased and $18,438,672 futures contracts sold.

Other Contracts — A fund may enter into total return swap agreements in order to attempt to obtain or preserve a particular return or spread at a lower cost than obtaining a return or spread through purchases and/or sales of instruments in other markets or gain exposure to certain markets in the most economical way possible. A fund will segregate cash, cash equivalents or other appropriate liquid securities on its records in amounts sufficient to meet requirements. Changes in value, including the periodic amounts of interest to be paid or received on swap agreements, are recorded as unrealized appreciation (depreciation) on swap agreements. Upon entering into a centrally cleared swap, a fund is required to deposit cash or securities (initial margin) with a financial intermediary in an amount equal to a certain percentage of the notional amount. 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 value and is a component of unrealized gains and losses. Realized gain or loss is recorded upon receipt or payment of a periodic settlement or termination of swap agreements. Net realized and unrealized gains or losses occurring during the holding period of swap agreements are a component of net realized gain (loss) on swap agreement transactions and change in net unrealized appreciation (depreciation) on swap agreements, respectively. The risks of entering into swap agreements include the possible lack of liquidity, failure of the counterparty to meet its obligations, and that there may be unfavorable changes in the underlying investments or instruments, including inflationary risk. The fund's average notional amount held during the period was $10,766,667.

8. Risk Factors

The value of the fund’s shares will go up and down, sometimes rapidly or unpredictably, based on the performance of the securities owned by the fund and other factors generally affecting the securities market. Market risks, including political, regulatory, economic and social developments, can affect the value of the fund’s investments. Natural disasters, public health emergencies, war, terrorism and other unforeseeable events may lead to increased market volatility and may have adverse long-term effects on world economies and markets generally.

The fund 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.

The 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 March 31, 2023 and March 31, 2022 were as follows:


	2023		2022
Distributions Paid From
Ordinary income	$	15,346,206	$	15,711,604
Long-term capital gains	—		$	2,791,809

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.

As of period end, the federal tax cost of investments and the components of distributable earnings on a tax-basis were as follows:


Federal tax cost of investments	$	446,698,076
Gross tax appreciation of investments	$	3,092,522
Gross tax depreciation of investments	(26,537,708)
Net tax appreciation (depreciation) of investments	(23,445,186)
Net tax appreciation (depreciation) on derivatives and translation of assets and liabilities in foreign currencies	33,121
Net tax appreciation (depreciation)	$	(23,412,065)
Other book-to-tax adjustments	$	(13,016)
Undistributed ordinary income	—
Accumulated short-term capital losses	$	(32,012,982)
Accumulated long-term capital losses	$	(28,462,293)

The difference between book-basis and tax-basis unrealized appreciation (depreciation) is attributable primarily to the realization for tax purposes of unrealized gains (losses) on futures contracts.

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.

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Trustees of American Century Investment Trust:

Opinion on the Financial Statements and Financial Highlights

We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of Core Plus Fund (the “Fund”), one of the funds constituting the American Century Investment Trust, as of March 31, 2023, the related statement of operations for the year then ended, the statements of changes in net assets and financial highlights for the two years in the period then ended, and the related notes. In our opinion, the financial statements and financial highlights present fairly, in all material respects, the financial position of Core Plus Fund of the American Century Investment Trust, as of March 31, 2023, and the results of its operations for the year then ended, the changes in its net assets, and the financial highlights for the two years then ended in conformity with accounting principles generally accepted in the United States of America. The financial highlights for each of the three years in the period ended March 31, 2021, were audited by other auditors, whose report, dated May 18, 2021, expressed an unqualified opinion on such financial highlights.

Basis for Opinion

These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on the Fund’s financial statements and financial highlights based on our audit. 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 Fund 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 Fund is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audit, 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 Fund’s 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 March 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

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). Independent trustees shall retire on December 31 of the year in which they reach their 76th 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 (more than three-fourths of the total number) 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, American Century Investment Services, Inc. (ACIS) 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 trustees serve in this capacity for eight (in the case of Jonathan S. Thomas, 16; and Jeremy I. Bulow, 9) registered investment companies in the American Century Investments family of funds.

The following table presents additional information about the trustees. The mailing address for each trustee other than Jonathan S. Thomas is 3945 Freedom Circle, Suite #800, Santa Clara, California 95054. The mailing address for Jonathan S. Thomas is 4500 Main Street, Kansas City, Missouri 64111.

Liquidity Risk Management Program

The Fund has adopted a liquidity risk management program (the “program”). The Fund’s 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 Fund’s liquidity risk, which is the risk that the Fund could not meet shareholder redemption requests without significant dilution of remaining shareholders’ interests in the Fund. This risk is managed by monitoring the degree of liquidity of the Fund’s investments, limiting the amount of the Fund’s illiquid investments, and utilizing various risk management tools and facilities available to the Fund for meeting shareholder redemptions, among other means. ACIM’s process of determining the degree of liquidity of certain investments held by the Fund is 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 Fund were noted in the report. In addition, ACIM provided its assessment that the program had been effective in managing the Fund’s 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.

You may elect a different withholding rate, or request zero withholding, by submitting an acceptable IRS Form W-4R election with your distribution request. You may notify us of your W-4R election by telephone, on our distribution forms, on IRS Form W-4R, or through other acceptable electronic means. If your withholding election is for an automatic withdrawal plan, you have the right to revoke your election at any time and any election you make will remain in effect until revoked by filing a new election.

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.

Portfolio Commentary

Performance Summary

Diversified Bond returned -5.56%* for the 12 months ended March 31, 2023. By comparison, the Bloomberg U.S. Aggregate Bond Index returned -4.78%. Fund returns reflect operating expenses, while index returns do not.

Inflation, Federal Reserve Policy Challenged Bond Market

Elevated inflation, aggressive Federal Reserve (Fed) policy, rising interest rates and mounting recession risk dominated the reporting period and contributed to heightened market volatility. After peaking in June, inflation moderated through March but remained well above the Fed’s target, which led to consistent interest rate hikes. In March, the collapse of two U.S. regional banks introduced a new market headwind, as banks moved to tighten lending standards amid industry uncertainty.

Duration Detracted from Relative Performance

We began modestly extending the portfolio’s duration in the second half of 2022, as short-maturity Treasury yields were climbing to multiyear highs. In our view, the combination of high inflation, rising Treasury yields and aggressive Fed tightening would eventually trigger a recession and push yields lower. However, yields rose overall, and our longer-than-index duration positioning suffered. The strategy did aid relative results late in the period when the bank failures sparked a flight to quality.

Security Selection Among Securitized Issues Enhanced Relative Performance

Security selection aided relative results, primarily in the securitized sector. Our investments in agency MBS and asset-backed securities contributed, largely due to solid performance late in the period. These results more than offset negative selection effects from non-agency collateralized mortgage obligations. In the investment-grade corporate sector, our security selections slightly detracted.

Elsewhere, an out-of-index stake in inflation-linked securities boosted results early in the reporting period, as inflation was climbing. We exited the position by the end of 2022 amid expectations for growth to slow and inflation to moderate. Conversely, out-of-index exposure to high-yield corporates, which we exited in early 2023, modestly detracted.

Notes to Financial Statements

MARCH 31, 2023

1. Organization

American Century Investment Trust (the trust) is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company and is organized as a Massachusetts business trust. Diversified Bond Fund (the fund) is one fund in a series issued by the trust. The fund’s investment objective is to seek a high level of income by investing in non-money market debt securities.

The fund offers the Investor Class, I Class, Y Class, A Class, C Class, R Class, R5 Class, R6 Class and G Class. The A Class may incur an initial sales charge. The A Class and C Class may be subject to a contingent deferred sales charge. Sale of the G Class commenced on May 19, 2022.

2. Significant Accounting Policies

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, U.S. Treasury and Government Agency securities, bank loan obligations, municipal securities and sovereign governments and agencies 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. Mortgage-related and asset-backed securities are valued based on models that consider trade data, prepayment and default projections, benchmark yield and spread data and estimated cash flows of each tranche of the issuer. Collateralized loan obligations are valued based on discounted cash flow models that consider trade and economic data, prepayment assumptions and default projections. Commercial paper is valued using a curve-based approach that considers money market rates for specific instruments, programs, currencies and maturity points from a variety of active market makers.

3. Fees and Transactions with Related Parties

The Investment Category Fee range, the Complex Fee range and the effective annual management fee for each class for the period ended March 31, 2023 are as follows:

7. Derivative Instruments

Interest Rate Risk — The fund is subject to interest rate risk in the normal course of pursuing its investment objectives. The value of bonds generally declines as interest rates rise. A fund may enter into futures contracts based on a bond index or a specific underlying security. 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 will segregate cash, cash equivalents or other appropriate liquid securities on its records in amounts sufficient to meet requirements. 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 futures 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 fund's average notional exposure to interest rate risk derivative instruments held during the period was $533,943,709 futures contracts purchased and $103,311,676 futures contracts sold.

8. Risk Factors

The 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 March 31, 2023 and March 31, 2022 were as follows:


	2023		2022
Distributions Paid From
Ordinary income	$	179,666,802	$	36,117,546
Long-term capital gains	—		$	15,866,572

The reclassifications, which are primarily due to merger adjustments, were made to capital paid in $137,252,975 and distributable earnings (loss) $(137,252,975).

As of period end, the federal tax cost of investments and the components of distributable earnings on a tax-basis were as follows:


Federal tax cost of investments	$	6,618,545,413
Gross tax appreciation of investments	$	47,258,160
Gross tax depreciation of investments	(313,715,063)
Net tax appreciation (depreciation) of investments	(266,456,903)
Net tax appreciation (depreciation) on derivatives and translation of assets and liabilities in foreign currencies	503,299
Net tax appreciation (depreciation)	$	(265,953,604)
Other book-to-tax adjustments	$	(159,872)
Undistributed ordinary income	—
Accumulated short-term capital losses	$	(399,229,177)
Accumulated long-term capital losses	$	(236,645,802)

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

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. Due to a shift in ownership of the fund, future capital loss carryover utilization in any given year is subject to Internal Revenue Code limitations. Any remaining accumulated gains after application of this limitation will be distributed to shareholders.

10. Reorganization

On December 16, 2021, the Board of Trustees approved an agreement and plan of reorganization (the reorganization), whereby the net assets of NT Diversified Bond Fund, one fund in a series issued by the trust, were transferred to Diversified Bond Fund in exchange for shares of Diversified Bond Fund. The purpose of the transaction was to combine two funds with substantially similar investment objectives and strategies. The financial statements and performance history of Diversified Bond Fund survived after the reorganization. The reorganization was effective at the close of the NYSE on May 27, 2022.

The reorganization was accomplished by a tax-free exchange of shares. On May 27, 2022, NT Diversified Bond Fund exchanged its shares for shares of Diversified Bond Fund as follows:


Original Fund/Class	Shares Exchanged	New Fund/Class	Shares Received
NT Diversified Bond Fund – G Class	427,890,190	Diversified Bond Fund – G Class	435,638,705

The net assets of NT Diversified Bond Fund and Diversified Bond Fund immediately before the reorganization were $4,331,988,616 and $1,779,254,262, respectively. NT Diversified Bond Fund's unrealized depreciation of $(309,319,355) was combined with that of Diversified Bond Fund. Immediately after the reorganization, the combined net assets were $6,111,242,878.

Assuming the reorganization had been completed on April 1, 2022, the beginning of the annual reporting period, the pro forma results of operations for the period ended March 31, 2023 are as follows:


Net investment income (loss)	$	199,276,299
Net realized and unrealized gain (loss)	(519,902,939)
Net increase (decrease) in net assets resulting from operations	$	(320,626,640)

Because the combined investment portfolios have been managed as a single integrated portfolio since the reorganization was completed, it is not practicable to separate the amounts of revenue and earnings of NT Diversified Bond Fund that have been included in the fund’s Statement of Operations since May 27, 2022.

Opinion on the Financial Statements and Financial Highlights

We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of Diversified Bond Fund (the “Fund”), one of the funds constituting the American Century Investment Trust, as of March 31, 2023, the related statement of operations for the year then ended, the statements of changes in net assets and financial highlights for the two years in the period then ended, and the related notes.

Average annual returns since inception are presented when ten years of performance history is not available. Y Class and G Class returns would have been lower if a portion of the fees had not been waived.

Sales charges include initial sales charges and contingent deferred sales charges (CDSCs), as applicable. A Class shares have a 4.50% maximum initial sales charge and may be subject to a maximum CDSC of 1.00%. The SEC requires that mutual funds provide performance information net of maximum sales charges in all cases where charges could be applied.

The fund acquired the net assets and assumed the historical performance of the Nomura High Yield Fund, a series of The Advisors’ Inner Circle Fund III on October 2, 2017. Accordingly, the performance shown for periods prior to October 2, 2017 represents the performance of Class I shares of the Nomura High Yield Fund. In addition, the Nomura High Yield Fund acquired the net assets and assumed the historical performance of the High Yield Fund, a series of Nomura Partners Funds, Inc. on December 8, 2014. Accordingly, the performance shown for periods before December 8, 2014 represents the performance of Class I shares of the High Yield Fund. The Nomura High Yield Fund and the High Yield Fund returns in the performance tables and graphs have not been adjusted to reflect the fund’s expenses. If the Nomura High Yield Fund and the High Yield Fund performance information had been adjusted to reflect the fund’s expenses, the performance may have been higher or lower for a given period depending on the expenses incurred by the Nomura High Yield Fund and the High Yield Fund for that period.

Performance Summary

High Income returned -3.57%* for the 12-month period ended March 31, 2023. By comparison, the ICE BofA U.S. High Yield Constrained Index returned -3.58%. Fund returns reflect operating expenses, while index returns do not.

Inflation, Central Bank Policy Created Challenging Backdrop

2022 was a year to remember for investors, as neither equities nor fixed income provided any respite from the relentless bear market. The Federal Reserve (Fed) and other global central banks spent 2022 aggressively withdrawing the liquidity they had pumped into their economies during the pandemic. Russia’s invasion of Ukraine added to investors’ consternation, driving up commodity prices and further snarling supply chains. As the year progressed, the global economy softened, sapping demand for commodities and providing breathing room to normalize supply chains.

Early in 2023, evidence of disinflation was the key driver of the broad-based rally. However, February brought an array of better-than-expected economic data, and the market reset its expectations for near-term Fed policy and reconsidered a potential recession. Market sentiment shifted even more bearish in March as inflation data came in hotter than expected and central bankers reiterated a hawkish stance.

While the economy had remained resilient, the consequences of dramatic monetary tightening appeared in March when significant bank failures emerged in the U.S. and Europe. Fast action by the Fed and other central banks to furnish liquidity eased the emerging crisis of confidence. A relief rally ensued, helping high-yield bonds to strengthen into period-end.

Sector, Duration Positioning Contributed to Results

High yield slumped alongside other asset classes in 2022 but rallied to begin 2023. The fund performed in line with the index in a challenging market environment. Overweight positions versus the index to the energy and leisure sectors and an underweight to retail lifted the portfolio’s relative performance.

Despite falling oil and natural gas prices, the energy sector contributed throughout the period as bond issuers continued to generate cash flow. Underweighting or avoiding problem credits also helped, particularly among retailers. Examples included used car dealer Carvana, shopping network QVC, online shopping portal Rakuten Group and home furnishings company Bed Bath & Beyond.

Additionally, duration positioning added value. We shifted from underweight duration to moderately overweight in late 2022, which aided results as yields declined in the first quarter of 2023.

Health Care Exposure Detracted

Heath care was the most meaningful sector detractor for the period. Hospitals hit some bumps on

the road to recovery from COVID-19-related volume declines and labor challenges. Additionally, pharmaceutical company Endo International struggled as it worked through a restructuring.

The portfolio’s modest tilt toward credit risk (via bonds with B and CCC credit ratings) also weighed on performance. Issuers with BB credit ratings outperformed the broader market, but our positive security selection within this category mitigated the impact.

Notes to Financial Statements

MARCH 31, 2023

1. Organization

American Century Investment Trust (the trust) is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company and is organized as a Massachusetts business trust. High Income Fund (the fund) is one fund in a series issued by the trust. The fund’s investment objective is to seek current yield and capital growth.

The fund offers the Investor Class, I Class, Y Class, A Class, R5 Class, R6 Class and G Class. The A Class may incur an initial sales charge and may be subject to a contingent deferred sales charge. Sale of the G Class commenced on May 19, 2022.

2. Significant Accounting Policies

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, bank loan obligations 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.

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

Investment Income — Interest income is recorded on the accrual basis and includes paydown gain (loss) and accretion of discounts and amortization of premiums. For convertible bonds, the premiums attributable only to the debt instrument are amortized. 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 fund may estimate the components of distributions received that may be considered nontaxable distributions or long-term capital gain distributions for income tax purposes.

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, the trust's distributor, American Century Investment Services, Inc. (ACIS), and the trust's transfer agent, American Century Services, LLC, are wholly owned, directly or indirectly, by ACC. ACIM has engaged Nomura Corporate Research and Asset Management Inc. (NCRAM) to serve as a subadvisor for the fund and to manage the fund’s assets. NCRAM is responsible for the day-to-day management of the fund, subject to the general supervision of the Board of Trustees and the investment advisor and in accordance with the investment objective, policies and restrictions of the fund. ACIM pays all costs associated with retaining NCRAM as the subadvisor of the fund. A subsidiary of NCRAM’s parent company indirectly owns a non-controlling equity interest in ACC. Various funds issued by American Century Asset Allocation Portfolios, Inc. own, in aggregate, 28% of the shares of the fund. Related parties do not invest in the fund for the purpose of exercising management or control.

The annual management fee for each class is as follows:


Investor Class	I Class	Y Class	A Class	R5 Class	R6 Class	G Class
0.775%	0.675%	0.575%	0.775%	0.575%	0.525%	0.000%(1)

(1)Effective annual management fee before waiver was 0.525%.

Distribution and Service Fees — The Board of Trustees has adopted a Master Distribution and Individual Shareholder Services Plan (the plan) for the A Class, pursuant to Rule 12b-1 of the 1940 Act. The plan provides that the A Class will pay ACIS an annual distribution and service fee of 0.25%. The fees are computed and accrued daily based on the A Class’s daily net assets and paid monthly in arrears. The fees are used to pay financial intermediaries for distribution and individual shareholder services. Fees incurred under the plan during the period ended March 31, 2023 are detailed in the Statement of Operations.

Interfund Transactions — The fund 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

7. Risk Factors

The fund invests primarily in high-yield and lower-quality debt securities, which are subject to substantial risks including liquidity risk and credit risk.

8. Federal Tax Information

The tax character of distributions paid during the years ended March 31, 2023 and March 31, 2022 were as follows:


	2023		2022
Distributions Paid From
Ordinary income	$	112,494,589	$	64,523,748
Long-term capital gains	$	1,543,036	$	1,705,338

The reclassifications, which are primarily due to merger adjustments, were made to capital $25,827,090 and

distributable earnings (loss) $(25,827,090).

As of period end, the federal tax cost of investments and the components of distributable earnings on a tax-basis were as follows:


Federal tax cost of investments	$	2,132,675,123
Gross tax appreciation of investments	$	18,633,115
Gross tax depreciation of investments	(222,203,727)
Net tax appreciation (depreciation) of investments	$	(203,570,612)
Other book-to-tax adjustments	$	(449,058)
Undistributed ordinary income	—
Accumulated short-term capital losses	$	(9,976,723)
Accumulated long-term capital losses	$	(65,503,508)

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. Due to a shift in ownership of the fund, future capital loss carryover utilization in any given

year is subject to Internal Revenue Code limitations. Any remaining accumulated gains after application of this

limitation will be distributed to shareholders.

9. Reorganization

On December 16, 2021, the Board of Trustees approved an agreement and plan of reorganization (the reorganization), whereby the net assets of NT High Income Fund, one fund in a series issued by the trust, were transferred to High Income Fund in exchange for shares of High Income Fund. The purpose of the transaction was to combine two funds with substantially similar investment objectives and strategies. The financial statements and performance history of High Income Fund survived after the reorganization. The reorganization was effective at the close of the NYSE on May 27, 2022.

The reorganization was accomplished by a tax-free exchange of shares. On May 27, 2022, NT High Income Fund exchanged its shares for shares of High Income Fund as follows:


Original Fund/Class	Shares Exchanged	New Fund/Class	Shares Received
NT High Income Fund - Investor Class	9,547,957	High Income Fund - Investor Class	9,811,652
NT High Income Fund - G Class	108,805,862	High Income Fund – G Class	111,810,857

The net assets of NT High Income Fund and High Income Fund immediately before the reorganization were $1,056,848,799 and $796,025,363, respectively. NT High Income Fund's unrealized depreciation of $(82,568,854) was combined with that of High Income Fund. Immediately after the reorganization, the combined net assets were $1,852,874,162.

Assuming the reorganization had been completed on April 1, 2022, the beginning of the annual reporting period, the pro forma results of operations for the period ended March 31, 2023 are as follows:


Net investment income (loss)	$	120,533,688
Net realized and unrealized gain (loss)	(191,033,995)
Net increase (decrease) in net assets resulting from operations	$	(70,500,307)

Because the combined investment portfolios have been managed as a single integrated portfolio since the reorganization was completed, it is not practicable to separate the amounts of revenue and earnings of NT High Income Fund that have been included in the fund’s Statement of Operations since May 27, 2022.

Portfolio Commentary

Portfolio Managers: Jeffrey Houston, Gavin Fleischman and Charles Tan

Performance Summary

High-Yield returned -4.61%* for the 12 months ended March 31, 2023, compared with the Bloomberg U.S. High-Yield 2% Issuer Capped Bond Index, which returned -3.35%. Fund returns reflect operating expenses, while index returns do not.

Inflation, Federal Reserve Policy Challenged Bond Market

Elevated inflation, aggressive Federal Reserve (Fed) policy, rising interest rates and mounting recession risk dominated the reporting period and contributed to heightened market volatility. After peaking in June, inflation moderated through March but remained well above the Fed’s target, which led to consistent interest rate hikes. In March, the collapse of two U.S. regional banks introduced a new market headwind, as banks moved to tighten lending standards amid industry uncertainty.

Against this backdrop, Treasury yields were volatile, particularly during the banking industry turmoil. For the period overall, yields rose sharply across the yield curve. This dynamic contributed to negative 12-month returns for most investment-grade bond market sectors, including Treasuries, mortgage-backed securities and corporate bonds. Concerns about slowing economic and earnings growth and a potential recession weighed on high-yield corporates, but the asset class generally fared better than investment-grade bonds and U.S. stocks.

Sector Allocations Detracted

Our sector allocations detracted from relative performance, largely due to consumer noncyclicals companies and the energy sector. Among consumer noncyclicals issuers, our overweight position versus the index in pharmaceuticals companies was a main detractor. In the energy sector, our underweight position in the oil field services industry, which delivered relatively strong performance, weighed on results.

From a quality perspective, an out-of-index position in investment-grade securities with BBB credit ratings modestly detracted. This was largely due to the position’s longer average duration, which hindered results as yields rose for the 12-month period.

On a positive note, our overweight position to the gaming industry and underweight to the retail sector aided relative performance.

Security Selection Added Value

Our security selection efforts were positive overall, particularly among consumer noncyclicals companies. Our selections in the pharmaceuticals industry boosted results due to our preference for higher quality holdings. Additionally, we underweighted Bausch Health, which significantly underperformed. In the energy sector, our investments in higher quality midstream companies aided relative performance.

Detractors included selections in the gaming industry, where our holdings in PENN Entertainment and Station Casinos underperformed their peers. In the finance sector, our position in longer-duration Air Lease Corporation, an aircraft leasing company, weighed on results. Elsewhere in the aircraft leasing industry, a position in Aircastle hybrid securities detracted. By period-end, we had exited our stakes in PENN Entertainment and Air Lease Corporation.

The fund offers the Investor Class, I Class, Y Class, A Class, C Class, R Class, R5 Class and R6 Class. The A Class may incur an initial sales charge. The A Class and C Class may be subject to a contingent deferred sales charge.

2. Significant Accounting Policies

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 bank loan obligations 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. Mortgage-related and asset-backed securities are valued based on models that consider trade data, prepayment and default projections, benchmark yield and spread data and estimated cash flows of each tranche of the issuer. Commercial paper is valued using a curve-based approach that considers money market rates for specific instruments, programs, currencies and maturity points from a variety of active market makers.

Open-end management investment companies are valued at the reported NAV per share. Repurchase agreements are valued at cost, which approximates fair value.

Investment Income — Interest income is recorded on the accrual basis and includes paydown gain (loss) and accretion of discounts and amortization of premiums. 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 fund may estimate the components of distributions received that may be considered nontaxable distributions or long-term capital gain distributions for income tax purposes. Securities lending income is net of fees and rebates earned by the lending agent for its services.

Securities Lending — Securities are lent to qualified financial institutions and brokers. State Street Bank & Trust Co. serves as securities lending agent to the fund pursuant to a Securities Lending Agreement. The lending of securities exposes the fund to risks such as: the borrowers may fail to return the loaned securities, the borrowers may not be able to provide additional collateral, the fund may experience delays in recovery of the loaned securities or delays in access to collateral, or the fund 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 fund 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 fund seeks to increase its net investment income through the receipt of interest and fees. Such income is reflected separately within the Statement of Operations. The value of loaned securities and related collateral outstanding at period end, if any, are shown on a gross basis within the Schedule of Investments and Statement 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 March 31, 2023.


Remaining Contractual Maturity of Agreements
	Overnight and Continuous		<30 days	Between 30 & 90 days	>90 days	Total
Securities Lending Transactions(1)
Corporate Bonds	$	8,161,630	—	—	—	$	8,161,630
Exchange-Traded Funds	3,179,460		—	—	—	3,179,460
Total Borrowings	$	11,341,090	—	—	—	$	11,341,090
Gross amount of recognized liabilities for securities lending transactions						$	11,341,090

(1)Amount represents the payable for cash collateral received for securities on loan. This will generally be in the Overnight and Continuous column as the securities are typically callable on demand.

Interfund Transactions — The fund 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.

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Trustees of American Century Investment Trust:

Opinion on the Financial Statements and Financial Highlights

We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of High-Yield Fund (the “Fund”), one of the funds constituting the American Century Investment Trust, as of March 31, 2023, the related statement of operations for the year then ended, the statements of changes in net assets and financial highlights for the two years in the period then ended, and the related notes. In our opinion, the financial statements and financial highlights present fairly, in all material respects, the financial position of High-Yield Fund of the American Century Investment Trust, as of March 31, 2023, and the results of its operations for the year then ended and the changes in its net assets and the financial highlights for the two years then ended in conformity with accounting principles generally accepted in the United States of America. The financial highlights for each of the three years in the period ended March 31, 2021, were audited by other auditors, whose report, dated May 18, 2021, expressed an unqualified opinion on such financial highlights.

Portfolio Commentary

Portfolio Managers: Jason Greenblath, Jeff Houston, Peter Van Gelderen and Charles Tan

As of August 1, 2022, Bob Gahagan left the portfolio's management team.

Performance Summary

Multisector Income returned -2.87%* for the 12 months ended March 31, 2023. By comparison, the Bloomberg U.S. Aggregate Bond Index returned -4.78% for the same period. Fund returns reflect operating expenses, while index returns do not.

Inflation, Federal Reserve Policy Challenged Bond Market

Elevated inflation, aggressive Federal Reserve (Fed) policy, rising interest rates and mounting recession risk dominated the reporting period and contributed to heightened market volatility. After peaking in June, inflation moderated through March but remained well above the Fed’s target, which led to consistent interest rate hikes. In March, the collapse of two U.S. regional banks introduced a new market headwind, as banks moved to tighten lending standards amid industry uncertainty.

Against this backdrop, Treasury yields were volatile, particularly during the banking industry turmoil. For the period overall, yields rose sharply across the yield curve. This dynamic contributed to negative 12-month returns for most investment-grade bond market sectors, including Treasuries, mortgage-backed securities and corporate bonds. Credit-sensitive and longer maturity securities generally posted the largest losses.

Duration Position Drove Relative Results

Given our expectations for interest rates to rise, we positioned the portfolio with a shorter duration than the index. As rates rose, this positioning aided relative performance. We added to our duration positioning in the second half of the period amid rising recession risk.

Corporate Credit Contributed

Our position in corporate bonds, which comprised approximately 45% of the portfolio on March 31, 2023, delivered positive relative results. This was largely due to our out-of-index allocation to high-yield corporate bonds. Additionally, we hedged the portfolio’s high-yield exposure with credit default swaps at various points during the reporting period. Our timely purchases and sales of these derivative securities aided results.

Investment-grade corporate bonds delivered mixed results, detracting from performance in the first half of the period and contributing in the second half. Positions in the banking, life insurance, real estate investment trusts and information technology sectors were among the key drivers of performance within the allocation. Late in the period, as economic growth concerns mounted, we shifted our corporate exposure to favor higher-credit-quality securities.

Securitized Sector Detracted

We maintained a sizable position in securitized bonds, which comprised approximately 27% of the portfolio at period-end. We primarily focused on non-index sectors, including non-agency collateralized mortgage obligations, non-agency commercial mortgage-backed securities, asset-backed securities and collateralized loan obligations. These credit-sensitive sectors generally struggled in the first half of the reporting period amid spread widening and heightened volatility. They rebounded in the second half, but not enough to offset earlier losses.

Elsewhere, our allocation to emerging markets, which totaled approximately 4% of the portfolio at March-end, detracted. We significantly reduced exposure during the period on valuation concerns.

Notes to Financial Statements

MARCH 31, 2023

1. Organization

American Century Investment Trust (the trust) is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company and is organized as a Massachusetts business trust. Multisector Income Fund (formerly Strategic Income Fund) (the fund) is one fund in a series issued by the trust. The fund’s investment objective is to seek income. As a secondary objective, the fund seeks long-term capital appreciation.

2. Significant Accounting Policies

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, U.S. Treasury and Government Agency securities, convertible bonds, bank loan obligations, and sovereign governments and agencies 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. Mortgage-related and asset-backed securities are valued based on models that consider trade data, prepayment and default projections, benchmark yield and spread data and estimated cash flows of each tranche of the issuer. Collateralized loan obligations are valued based on discounted cash flow models that consider trade and economic data, prepayment assumptions and default projections. Fixed income 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.

Investment Income — Interest income is recorded on the accrual basis and includes paydown gain (loss) and accretion of discounts and amortization of premiums. Inflation adjustments related to inflation-linked debt securities are reflected as interest income. Securities lending income is net of fees and rebates earned by the lending agent for its services.

7. Derivative Instruments

Interest Rate Risk — The fund is subject to interest rate risk in the normal course of pursuing its investment objectives. The value of bonds generally declines as interest rates rise. A fund may enter into futures contracts based on a bond index or a specific underlying security. 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 will segregate cash, cash equivalents or other appropriate liquid securities on its records in amounts sufficient to meet requirements. 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 futures 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 fund's average notional exposure to interest rate risk derivative instruments held during the period was $16,010,725 futures contracts purchased and $1,591,736 futures contracts sold.

8. Risk Factors

The fund invests in lower-rated debt securities, which are subject to substantial risks including liquidity risk and credit risk.

The 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 March 31, 2023 and March 31, 2022 were as follows:


	2023		2022
Distributions Paid From
Ordinary income	$	3,204,035	$	3,271,308
Long-term capital gains	—		$	277,051

As of period end, the federal tax cost of investments and the components of distributable earnings on a tax-basis were as follows:


Federal tax cost of investments	$	89,056,967
Gross tax appreciation of investments	$	846,461
Gross tax depreciation of investments	(3,549,350)
Net tax appreciation (depreciation) of investments	(2,702,889)
Net tax appreciation (depreciation) on derivatives and translation of assets and liabilities in foreign currencies	3
Net tax appreciation (depreciation)	$	(2,702,886)
Other book-to-tax adjustments	$	(25,347)
Undistributed ordinary income	—
Accumulated short-term capital losses	$	(4,672,090)
Accumulated long-term capital losses	$	(2,243,937)

The difference between book-basis and tax-basis unrealized appreciation (depreciation) is attributable primarily to the realization for tax purposes of unrealized gains (losses) on futures contracts. Other book-to tax adjustments are attributable primarily to the tax deferral of losses on straddle positions.

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.

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Trustees of American Century Investment Trust:

Opinion on the Financial Statements and Financial Highlights

We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of Multisector Income Fund (formerly Strategic Income Fund) (the “Fund”), one of the funds constituting the American Century Investment Trust, as of March 31, 2023, the related statement of operations for the year then ended, the statements of changes in net assets and financial highlights for the two years in the period then ended, and the related notes. In our opinion, the financial statements and financial highlights present fairly, in all material respects, the financial position of Multisector Income Fund of the American Century Investment Trust, as of March 31, 2023, and the results of its operations for the year then ended, the changes in its net assets, and the financial highlights for the two years then ended in conformity with accounting principles generally accepted in the United States of America. The financial highlights for each of the three years in the period ended March 31, 2021, were audited by other auditors, whose report, dated May 18, 2021, expressed an unqualified opinion on such financial highlights.

Data presented reflect past performance. Past performance is no guarantee of future results. Current performance may be higher or lower than the performance shown.

For additional information about the fund, please consult the prospectus.

You could lose money by investing in the fund. Although the fund seeks to preserve the value of your investment at $1.00 per share, it cannot guarantee it will do so. The fund may impose a fee upon sale of your shares or may temporarily suspend your ability to sell shares if the fund’s liquidity falls below required minimums because of market conditions or other factors. An investment in the fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The fund’s sponsor has no legal obligation to provide financial support to the fund, and you should not expect that the sponsor will provide financial support to the fund at any time.

The 7-day current yield more closely reflects the current earnings of the fund than the total return.

Notes to Financial Statements

MARCH 31, 2023

1. Organization

American Century Investment Trust (the trust) is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company and is organized as a Massachusetts business trust. Prime Money Market Fund (the fund) is one fund in a series issued by the trust. The fund’s investment objective is to seek to earn the highest level of current income while preserving the value of your investment.

The fund offers the Investor Class, A Class and C Class. The A Class and C Class may be subject to a contingent deferred sales charge.

2. Significant Accounting Policies

Investment Valuations — The fund determines the fair value of its investments and computes its 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 fund is 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. Investments are generally valued at amortized cost, which approximates fair value. If the valuation designee determines that the valuation methods do not reflect an investment’s fair value, such investment is valued as determined in good faith by the valuation designee.

Investment Income — Interest income is recorded on the accrual basis and includes accretion of discounts and amortization of premiums. The fund may purchase a security and at the same time make a commitment to sell the same security at a future settlement date at a specified price. The difference between the purchase price and the sale price of these simultaneous transactions is reflected as interest income.

Distributions to Shareholders — Distributions from net investment income, if any, are declared daily and paid monthly. The fund may make capital gains distributions to comply with the distribution requirements of the Internal Revenue Code.

3. Fees and Transactions with Related Parties

Management Fees — The trust has entered into a management agreement with ACIM, under which ACIM provides the fund with investment advisory and management services in exchange for a single, unified management fee (the fee) per class. The agreement provides that ACIM will pay all expenses of managing and operating the fund, except brokerage expenses, taxes, interest, fees and expenses of the independent trustees (including legal counsel fees), extraordinary expenses, and expenses incurred in connection with the provision of shareholder services and distribution services under a plan adopted pursuant to Rule 12b-1 under the 1940 Act. The fee is computed and accrued daily based on each class’s daily net assets and paid monthly in arrears. The fee consists of (1) an Investment Category Fee based on the daily net assets of the fund and certain other accounts managed by the investment advisor that are in the same broad investment category as the fund and (2) a Complex Fee based on the assets of all funds in the American Century Investments family of funds that have the same investment advisor and distributor as the fund. For purposes of determining the Investment Category Fee and Complex Fee, the assets of funds managed by the investment advisor that invest exclusively in the shares of other funds (funds of funds) are not included. The rates for the Investment Category Fee range from 0.2370% to 0.3500% and the rates for the Complex Fee range from 0.2500% to 0.3100%. In order to maintain a positive yield, ACIM may voluntarily waive a portion of the management fee on a daily basis. The fee waiver may be revised or terminated at any time by the investment advisor without notice. The total amount of the waiver for each class for the period ended March 31, 2023 was $59,999, $758 and $238 for Investor Class, A Class and C Class, respectively. The effective annual management fee before and after waiver for each class for the period ended March 31, 2023 was 0.57%.

Distribution and Service Fees — The Board of Trustees has adopted a separate Master Distribution and Individual Shareholder Services Plan for each of the A Class and C Class (collectively the plans), pursuant to Rule 12b-1 of the 1940 Act. The plans provide that the A Class will pay ACIS an annual distribution and service fee of 0.25%. The plans provide that the C Class will pay ACIS an annual distribution and service fee of 0.75%, of which 0.25% is paid for individual shareholder services and 0.50% is paid for distribution services. The fees are computed and accrued daily based on each class’s daily net assets and paid monthly in arrears. The fees are used to pay financial intermediaries for distribution and individual shareholder services. Fees incurred under the plans during the period ended March 31, 2023 are detailed in the Statement of Operations.

In order to maintain a positive yield, all or a portion of the distribution and/or service fee may voluntarily be waived on a daily basis. The fee waiver may be revised or terminated at any time without notice. The total amount of the waiver for the period ended March 31, 2023 was $4,899 and $7,172 for the A Class and C Class, respectively. The effective annual distribution and service fee after waiver was 0.23% for the A Class and 0.60% for C Class.

Portfolio Commentary

Portfolio Managers: Bob Gahagan, Peter Van Gelderen, Jeff Houston, James Platz and Charles Tan

Performance Summary

Short Duration returned 0.00%* for the 12 months ended March 31, 2023. By comparison, the Bloomberg U.S. 1-3 Year Government/Credit Bond Index returned 0.26%. Fund returns reflect operating expenses, while index returns do not.

Inflation, Federal Reserve Policy Challenged Bond Market

Elevated inflation, aggressive Federal Reserve (Fed) policy, rising interest rates and mounting recession risk dominated the reporting period and contributed to heightened market volatility. After peaking in June, inflation moderated through March but remained well above the Fed’s target, which led to consistent interest rate hikes. In March, the collapse of two U.S. regional banks introduced a new market headwind, as banks moved to tighten lending standards amid industry uncertainty.

Against this backdrop, Treasury yields were volatile, particularly during the banking industry turmoil. For the period overall, yields rose sharply across the yield curve. This dynamic contributed to negative 12-month returns for most investment-grade bond market sectors, including Treasuries, mortgage-backed securities and corporate bonds. Credit-sensitive and longer maturity securities generally posted the largest losses.

Duration Was a Modest Detractor

Sector Allocation, Security Selection Enhanced Relative Performance

Overall, sector allocation was a top contributor to relative results, partly due to a slightly larger-than-usual position in cash and cash equivalents. These positions benefited from the Fed’s aggressive rate-hike campaign. Additionally, out-of-index exposure to high-yield securities boosted results, largely due to our hedging strategy, which included timely purchases of high-yield credit default swaps.

The cash and high-yield allocations more than offset slightly negative results from an out-of-index allocation to securitized securities. Our securitized exposure primarily consisted of credit-sensitive non-agency collateralized mortgage obligations, non-agency commercial mortgage-backed securities, asset-backed securities and collateralized loan obligations.

Security selection also had a broadly positive effect on relative performance. Our selections among government securities and investment-grade corporates were the main drivers, while our U.S. dollar-denominated emerging markets bonds had a flat effect on results.

*All fund returns referenced in this commentary are for Investor Class shares. Fund returns would have been lower if a portion of the fees had not been waived. Performance for other share classes will vary due to differences in fee structure; when Investor Class performance exceeds that of the index, other share classes may not.

Notes to Financial Statements

MARCH 31, 2023

1. Organization

American Century Investment Trust (the trust) is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company and is organized as a Massachusetts business trust. Short Duration Fund (the fund) is one fund in a series issued by the trust. The fund’s investment objective is to seek to maximize total return. As a secondary objective, the fund seeks a high level of income.

The fund offers the Investor Class, I Class, A Class, C Class, R Class, R5 Class, R6 Class and G Class. The A Class may incur an initial sales charge. The A Class and C Class may be subject to a contingent deferred sales charge.

2. Significant Accounting Policies

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, U.S. Treasury and Government Agency securities, and bank loan obligations 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. Mortgage-related and asset-backed securities are valued based on models that consider trade data, prepayment and default projections, benchmark yield and spread data and estimated cash flows of each tranche of the issuer. Collateralized loan obligations are valued based on discounted cash flow models that consider trade and economic data, prepayment assumptions and default projections. Commercial paper is valued using a curve-based approach that considers money market rates for specific instruments, programs, currencies and maturity points from a variety of active market makers.

3. Fees and Transactions with Related Parties

Management Fees — The trust has entered into a management agreement with ACIM, under which ACIM provides the fund with investment advisory and management services in exchange for a single, unified management fee (the fee) per class. The agreement provides that ACIM will pay all expenses of managing and operating the fund, except brokerage expenses, taxes, interest, fees and expenses of the independent trustees (including legal counsel fees), extraordinary expenses, and expenses incurred in connection with the provision of shareholder services and distribution services under a plan adopted pursuant to Rule 12b-1 under the 1940 Act. The fee is computed and accrued daily based on each class’s daily net assets and paid monthly in arrears. The difference in the fee among the classes is a result of their separate arrangements for non-Rule 12b-1 shareholder services. It is not the result of any difference in advisory or custodial fees or other expenses related to the management of the fund's assets, which do not vary by class. The fee consists of (1) an Investment Category Fee based on the daily net assets of the fund and certain other accounts managed by the investment advisor that are in the same broad investment category as the fund and (2) a Complex Fee based on the assets of all funds in the American Century Investments family of funds that have the same investment advisor and distributor as the fund. For purposes of determining the Investment Category Fee and Complex Fee, the assets of funds managed by the investment advisor that invest exclusively in the shares of other funds (funds of funds) are not included. Effective August 1, 2022, the investment advisor agreed to waive 0.02% of the fund's management fee. The investment advisor expects this waiver to continue until July 31, 2023 and cannot terminate it prior to such date without the approval of the Board of Trustees. The investment advisor agreed to waive the G Class's management fee in its entirety. The investment advisor expects this waiver to remain in effect permanently and cannot terminate it without the approval of the Board of Trustees.

The Investment Category Fee range, the Complex Fee range and the effective annual management fee before and after waiver for each class for the period ended March 31, 2023 are as follows:


			Effective Annual Management Fee
	Investment Category Fee Range	Complex Fee Range	Before Waiver	After Waiver
Investor Class	0.2825% to 0.4000%	0.2500% to 0.3100%	0.58%	0.57%
I Class		0.1500% to 0.2100%	0.48%	0.47%
A Class		0.2500% to 0.3100%	0.58%	0.57%
C Class		0.2500% to 0.3100%	0.58%	0.57%
R Class		0.2500% to 0.3100%	0.58%	0.57%
R5 Class		0.0500% to 0.1100%	0.38%	0.37%
R6 Class		0.0000% to 0.0600%	0.33%	0.32%
G Class		0.0000% to 0.0600%	0.33%	0.00%

Interfund Transactions — The fund 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 of investment securities, excluding short-term investments, for the period ended March 31, 2023 totaled $2,601,050,503, of which $1,940,601,858 represented U.S. Treasury and Government Agency obligations.

7. Derivative Instruments

Interest Rate Risk — The fund is subject to interest rate risk in the normal course of pursuing its investment objectives. The value of bonds generally declines as interest rates rise. A fund may enter into futures contracts based on a bond index or a specific underlying security. 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 will segregate cash, cash equivalents or other appropriate liquid securities on its records in amounts sufficient to meet requirements. 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 futures 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 fund's average notional exposure to interest rate risk derivative instruments held during the period was $259,995,578 futures contracts purchased and $178,097,717 futures contracts sold.

Value of Derivative Instruments as of March 31, 2023

8. Risk Factors

The 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 March 31, 2023 and March 31, 2022 were as follows:


	2023		2022
Distributions Paid From
Ordinary income	$	43,069,155	$	39,127,627
Long-term capital gains	—		—

As of period end, the federal tax cost of investments and the components of distributable earnings on a tax-basis were as follows:


Federal tax cost of investments	$	1,386,115,676
Gross tax appreciation of investments	$	5,219,830
Gross tax depreciation of investments	(37,736,007)
Net tax appreciation (depreciation) of investments	(32,516,177)
Net tax appreciation (depreciation) on derivatives	139,257
Net tax appreciation (depreciation)	$	(32,376,920)
Other book-to-tax adjustments	$	(1,984,603)
Undistributed ordinary income	—
Accumulated short-term capital losses	$	(35,873,796)
Accumulated long-term capital losses	$	(31,783,090)

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

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.

Portfolio Commentary

Portfolio Managers: Bob Gahagan, Jim Platz and Miguel Castillo

Performance Summary

Short Duration Inflation Protection Bond returned -1.48%* for the 12 months ended March 31, 2023. By comparison, the Bloomberg U.S. 1-5 Year Treasury Inflation Protected Securities (TIPS) Index returned -1.14%. Fund returns reflect operating expenses, while index returns do not.

Inflation, Federal Reserve Policy Challenged Bond Market

Meanwhile, the 10-year breakeven rate (the yield difference between nominal 10-year Treasuries and 10-year TIPS and a key measure of market-based inflation expectations) experienced quarter-to-quarter volatility but eased overall, from 2.84% to 2.32%. Theoretically, the breakeven rate indicates the market’s expectations for inflation for the next 10 years and also reflects the inflation rate required for TIPS to outperform nominal Treasuries during that period (2.32% or higher as of March 31).

Against this backdrop, Treasury yields were volatile, particularly during the banking industry turmoil. For the period overall, Treasury yields rose sharply across the yield curve. TIPS yields started the period in negative territory and climbed steadily into positive territory. Higher yields contributed to negative 12-month returns for most investment-grade bond market sectors, including TIPS, which were among the weakest.

Non-Index Holdings Weighed on Results

Out-of-index exposure to securitized and corporate securities detracted from results. Rising yields and heightened volatility during the reporting period broadly weighed on credit-sensitive securities.

Duration Detracted from Relative Performance

Inflation Exposure Boosted Relative Results

We generally favored the shorter maturity inflation-protected securities in the portfolio’s maturity

range, which fared better than longer maturity securities amid elevated inflation. This strategy had

a positive effect on relative performance.

We also held inflation swaps in conjunction with out-of-index securitized and corporate bonds. Inflation swaps diversified the portfolio’s inflation protection and created an inflation overlay for non-inflation-linked securitized and corporate securities. Inflation swaps are fixed-maturity instruments, negotiated through a counterparty (investment bank), that return the rate of inflation (Consumer Price Index). All swaps bear counterparty credit risk, but American Century Investments applies stringent controls and oversight regarding this risk.Our swaps strategy generally aided results, most significantly early in the period when the swaps weighting gave the portfolio greater sensitivity to inflation than the index.

By mid-2022, we reduced the portfolio’s overweight inflation exposure. This was due to our expectations for inflation to continue moderating amid Fed hawkishness and a likely recession. We expect to increase the portfolio’s inflation sensitivity as TIPS valuations improve.

MARCH 31, 2023

1. Organization

American Century Investment Trust (the trust) is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company and is organized as a Massachusetts business trust. Short Duration Inflation Protection Bond Fund (the fund) is one fund in a series issued by the trust. The fund’s investment objective is to pursue total return using a strategy that seeks to protect against U.S. inflation.

2. Significant Accounting Policies

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 U.S. Treasury and Government Agency securities 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. Mortgage-related and asset-backed securities are valued based on models that consider trade data, prepayment and default projections, benchmark yield and spread data and estimated cash flows of each tranche of the issuer. Collateralized loan obligations are valued based on discounted cash flow models that consider trade and economic data, prepayment assumptions and default projections. Commercial paper is valued using a curve-based approach that considers money market rates for specific instruments, programs, currencies and maturity points from a variety of active market makers.

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

3. Fees and Transactions with Related Parties

the 1940 Act. The fee is computed and accrued daily based on each class’s daily net assets and paid monthly in arrears. The difference in the fee among the classes is a result of their separate arrangements for non-Rule

12b-1 shareholder services. It is not the result of any difference in advisory or custodial fees or other expenses related to the management of the fund's assets, which do not vary by class. The fee consists of (1) an Investment Category Fee based on the daily net assets of the fund and certain other accounts managed by the investment advisor that are in the same broad investment category as the fund and (2) a Complex Fee based on the assets of all funds in the American Century Investments family of funds that have the same investment advisor and distributor as the fund. For purposes of determining the Investment Category Fee and Complex Fee, the assets of funds managed by the investment advisor that invest exclusively in the shares of other funds (funds of funds) are not included. The investment advisor agreed to waive the G Class's management fee in its entirety. The investment advisor expects this waiver to remain in effect permanently and cannot terminate it without the approval of the Board of Trustees.

The Investment Category Fee range, the Complex Fee range and the effective annual management fee for each class for the period ended March 31, 2023 are as follows:


	Investment Category Fee Range	Complex Fee Range	Effective Annual Management Fee
Investor Class	0.2625% to 0.3800%	0.2500% to 0.3100%	0.56%
I Class		0.1500% to 0.2100%	0.46%
Y Class		0.0500% to 0.1100%	0.36%
A Class		0.2500% to 0.3100%	0.56%
C Class		0.2500% to 0.3100%	0.56%
R Class		0.2500% to 0.3100%	0.56%
R5 Class		0.0500% to 0.1100%	0.36%
R6 Class		0.0000% to 0.0600%	0.31%
G Class		0.0000% to 0.0600%	0.00%(1)

(1)Effective annual management fee before waiver was 0.31%.

Interfund Transactions — The fund 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.

7. Derivative Instruments

Interest Rate Risk — The fund is subject to interest rate risk in the normal course of pursuing its investment objectives. The value of bonds generally declines as interest rates rise. A fund may enter into futures contracts based on a bond index or a specific underlying security. 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 will segregate cash, cash equivalents or other appropriate liquid securities on its records in amounts sufficient to meet requirements. 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 futures 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 fund's average notional exposure to interest rate risk derivative instruments held during the period was $112,133,906 futures contracts purchased and $42,655,000 futures contracts sold.

8. Risk Factors

9. Federal Tax Information

The tax character of distributions paid during the years ended March 31, 2023 and March 31, 2022 were as follows:


	2023		2022
Distributions Paid From
Ordinary income	$	131,002,156	$	109,162,116
Long-term capital gains	$	15,230,972	—

As of period end, the federal tax cost of investments and the components of distributable earnings on a tax-basis were as follows:


Federal tax cost of investments	$	2,370,661,055
Gross tax appreciation of investments	$	887,785
Gross tax depreciation of investments	(119,727,006)
Net tax appreciation (depreciation) of investments	(118,839,221)
Net tax appreciation (depreciation) on derivatives	58,134,642
Net tax appreciation (depreciation)	$	(60,704,579)
Undistributed ordinary income	$	8,847,140
Accumulated short-term capital losses	$	(23,821,315)
Accumulated long-term capital losses	$	(18,946,081)

The difference between book-basis and tax-basis unrealized appreciation (depreciation) is attributable primarily to the realization for tax purposes of unrealized gain (losses) on futures contracts.

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.

Portfolio Commentary

Portfolio Managers: Jason Greenblath, Jeff Houston, Peter Van Gelderen and Charles Tan

As of August 1, 2022, Bob Gahagan left the portfolio management team.

Performance Summary

Short Duration Strategic Income returned -1.24%* for the 12 months ended March 31, 2023. By comparison, the Bloomberg U.S. 1-3 Year Government/Credit Bond Index returned 0.26% for the same period. Fund returns reflect operating expenses, while index returns do not.

Inflation, Federal Reserve Policy Challenged Bond Market

Elevated inflation, aggressive Federal Reserve (Fed) policy, rising interest rates and mounting recession risk dominated the reporting period and contributed to heightened market volatility. After peaking in June, inflation moderated through March but remained well above the Fed’s target, which led to consistent interest rate hikes. In March, the collapse of two U.S. regional banks introduced a new market headwind, as banks moved to tighten lending standards amid industry uncertainty.

Against this backdrop, Treasury yields were volatile, particularly during the banking industry turmoil. For the period overall, yields rose sharply across the yield curve. This dynamic contributed to negative 12-month returns for most investment-grade bond market sectors, including Treasuries, mortgage-backed securities and corporate bonds. Credit-sensitive and longer maturity securities generally posted the largest losses.

Securitized, Credit Sectors Detracted

We allocated approximately 26% of the portfolio at period-end in various subsectors within the securitized asset class. We primarily focused on non-agency collateralized mortgage obligations (CMOs), non-agency commercial mortgage-backed securities (CMBS), asset-backed securities (ABS) and collateralized loan obligations (CLOs). Lagging results from CMOs and CMBS weighed down the overall results from the securitized sector. Positive relative results from CLOs and ABS helped offset some of the losses.

Although we reduced the portfolio’s credit exposure as the period progressed, we continued to uncover attractive yield-generating opportunities. These securities comprised approximately 44% of the portfolio at period-end. Our allocation included high-yield securities, which detracted from overall results. Our selections among investment-grade corporates also weighed on relative results for the period.

Elsewhere, our allocation to emerging markets, which we reduced during the period, and a small position in preferred stocks detracted.

Cash Holdings Provided a Lift

Our larger-than-usual position in cash and cash equivalents delivered a boost to relative results, benefiting from the Fed’s aggressive rate-hike campaign. We believe several factors, including rising recession risk, banking system uncertainty, slowing cash flows from weaker revenue growth and margin compression, will push credit spreads wider in the near term. In this environment, the portfolio’s higher liquidity gives us the flexibility to add back credit risk when we believe valuations appear attractive.

Notes to Financial Statements

MARCH 31, 2023

1. Organization

American Century Investment Trust (the trust) is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company and is organized as a Massachusetts business trust. Short Duration Strategic Income Fund (the fund) is one fund in a series issued by the trust. The fund’s investment objective is to seek income. As a secondary objective, the fund seeks long-term capital appreciation.

2. Significant Accounting Policies

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, U.S. Treasury and Government Agency securities, convertible bonds, bank loan obligations, and sovereign governments and agencies 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. Mortgage-related and asset-backed securities are valued based on models that consider trade data, prepayment and default projections, benchmark yield and spread data and estimated cash flows of each tranche of the issuer. Collateralized loan obligations are valued based on discounted cash flow models that consider trade and economic data, prepayment assumptions and default projections. Fixed income 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.

3. Fees and Transactions with Related Parties

The annual management fee for each class is as follows:


Investor Class	I Class	Y Class	A Class	C Class	R Class	R5 Class	R6 Class
0.51%	0.41%	0.31%	0.51%	0.51%	0.51%	0.31%	0.26%

Interfund Transactions — The fund 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 of investment securities, excluding short-term investments, for the period ended March 31, 2023 totaled $1,424,856,647, of which $717,835,353 represented U.S. Treasury and Government Agency obligations.

7. Derivative Instruments

Interest Rate Risk — The fund is subject to interest rate risk in the normal course of pursuing its investment objectives. The value of bonds generally declines as interest rates rise. A fund may enter into futures contracts based on a bond index or a specific underlying security. 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 will segregate cash, cash equivalents or other appropriate liquid securities on its records in amounts sufficient to meet requirements. 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 futures 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 fund's average notional exposure to interest rate risk derivative instruments held during the period was $62,114,943 futures contracts purchased and $80,091,302 futures contracts sold.

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Trustees of American Century Investment Trust:

Opinion on the Financial Statements and Financial Highlights

We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of Short Duration Strategic Income Fund (the “Fund”), one of the funds constituting the American Century Investment Trust, as of March 31, 2023, the related statement of operations for the year then ended, the statements of changes in net assets and financial highlights for the two years in the period then ended, and the related notes. In our opinion, the financial statements and financial highlights present fairly, in all material respects, the financial position of Short Duration Strategic Income Fund of the American Century Investment Trust, as of March 31, 2023, and the results of its operations for the year then ended and the changes in its net assets and the financial highlights for the two years then ended in conformity with accounting principles generally accepted in the United States of America. The financial highlights for each of the three years in the period ended March 31, 2021, were audited by other auditors, whose report, dated May 18, 2021, expressed an unqualified opinion on such financial highlights.

Data presented reflect past performance. Past performance is no guarantee of future results. Current performance may be higher or lower than the performance shown.

You could lose money by investing in the fund. Although the fund seeks to preserve the value of your investment at $1.00 per share, it cannot guarantee it will do so. An investment in the fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The fund’s sponsor has no legal obligation to provide financial support to the fund, and you should not expect that the sponsor will provide financial support to the fund at any time.

The 7-day current yield more closely reflects the current earnings of the fund than the total return.

Notes to Financial Statements

MARCH 31, 2023

1. Organization

American Century Investment Trust (the trust) is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company and is organized as a Massachusetts business trust. U.S. Government Money Market Fund (the fund) is one fund in a series issued by the trust. The fund’s investment objective is to seek current income while maintaining liquidity and preserving capital.

The fund offers the Investor Class, A Class and C Class. The A Class and C Class may be subject to a contingent deferred sales charge. On January 13, 2023, there were no outstanding G Class shares and the fund discontinued offering G Class.

2. Significant Accounting Policies

Investment Valuations — The fund determines the fair value of its investments and computes its 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 fund is 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. Investments are generally valued at amortized cost, which approximates fair value. Repurchase agreements are valued at cost, which approximates fair value. If the valuation designee determines that the valuation methods do not reflect an investment’s fair value, such investment is valued as determined in good faith by the valuation designee.

3. Fees and Transactions with Related Parties

Management Fees — The trust has entered into a management agreement with ACIM, under which ACIM provides the fund with investment advisory and management services in exchange for a single, unified management fee (the fee) per class. The agreement provides that ACIM will pay all expenses of managing and operating the fund, except brokerage expenses, taxes, interest, fees and expenses of the independent trustees (including legal counsel fees), extraordinary expenses, and expenses incurred in connection with the provision of shareholder services and distribution services under a plan adopted pursuant to Rule 12b-1 under the 1940 Act. The fee is computed and accrued daily based on each class’s daily net assets and paid monthly in arrears. The fee consists of (1) an Investment Category Fee based on the daily net assets of the fund and certain other accounts managed by the investment advisor that are in the same broad investment category as the fund and (2) a Complex Fee based on the assets of all funds in the American Century Investments family of funds that have the same investment advisor and distributor as the fund. For purposes of determining the Investment Category Fee and Complex Fee, the assets of funds managed by the investment advisor that invest exclusively in the shares of other funds (funds of funds) are not included. During the period, the investment advisor waived the G Class's management fee in its entirety. In order to maintain a positive yield, ACIM may voluntarily waive a portion of the management fee on a daily basis. The fee waiver may be revised or terminated at any time by the investment advisor without notice. The total amount of the waiver for each class for the period ended March 31, 2023 was $94, $12 and $56,239 for Investor Class, A Class and G Class, respectively.

The Investment Category Fee range, the Complex Fee range and the effective annual management fee before and after waiver for each class for the period ended March 31, 2023 are as follows:


			Effective Annual Management Fee
	Investment Category Fee Range	Complex Fee Range	Before Waiver	After Waiver
Investor Class	0.1170% to 0.2300%	0.2500% to 0.3100%	0.45%	0.45%
A Class			0.45%	0.45%
C Class			0.45%	0.45%
G Class			0.45%	0.00%

In order to maintain a positive yield, all or a portion of the distribution and/or service fee may voluntarily be waived on a daily basis. The fee waiver may be revised or terminated at any time without notice. The total amount of the waiver for the period ended March 31, 2023 was $16,674 and $334 for the A Class and C Class, respectively. The effective annual distribution and service fee after waiver was 0.23% for the A Class and 0.67% for C Class.

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Trustees of American Century Investment Trust:

Opinion on the Financial Statements and Financial Highlights

We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of U.S. Government Money Market Fund (the “Fund”), one of the funds constituting the American Century Investment Trust, as of March 31, 2023, the related statement of operations for the year then ended, the statements of changes in net assets and financial highlights for the two years in the period then ended, and the related notes. In our opinion, the financial statements and financial highlights present fairly, in all material respects, the financial position of U.S. Government Money Market Fund of the American Century Investment Trust, as of March 31, 2023, and the results of its operations for the year then ended and the changes in its net assets and the financial highlights for the two years then ended in conformity with accounting principles generally accepted in the United States of America. The financial highlights for each of the three years in the period ended March 31, 2021, were audited by other auditors, whose report, dated May 18, 2021, expressed an unqualified opinion on such financial highlights.
