Invesco Advisers, Inc.

Unless Invesco continues the fee waiver agreement, it will terminate on December 31, 2024. During its term, the fee waiver agreement cannot be terminated or amended to increase the expense limit without approval of the Board of Trustees.

Example. This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain equal to the Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement in the first year and the Total Annual Fund Operating Expenses thereafter.

Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

Unless Invesco continues the fee waiver agreement, it will terminate on December 31, 2024. During its term, the fee waiver agreement cannot be terminated or amended to increase the expense limit without approval of the Board of Trustees.

Principal Investment Strategies of the Fund

The Fund invests in high-quality U.S. dollar denominated obligations with maturities of 60 calendar days or less, including: (i) securities issued by the U.S. government or its agencies; (ii) certificates of deposit and time deposits from U.S. or foreign banks; (iii) repurchase agreements; (iv) commercial paper; and (v) municipal securities.

The Fund may engage in repurchase agreement transactions that are collateralized by cash or government securities. In addition, it may engage in repurchase agreement transactions that are collateralized by nongovernment securities such as equity securities and fixed income securities that are rated investment grade and below investment grade by nationally recognized statistical rating organizations or unrated securities of comparable quality.

The Fund is a money market fund that rounds the Fund’s current net asset value (NAV) per share to a minimum of the fourth decimal place. Although the Fund is a money market fund, the NAV of the Fund’s shares “floats,” fluctuating with changes in the values of the Fund’s portfolio securities.

The Fund invests in conformity with U.S. Securities and Exchange Commission (SEC) rules and regulation requirements for money market funds for the quality, maturity, diversification and liquidity of investments. The Fund invests only in U.S. dollar-denominated securities maturing within 60 calendar days of the date of purchase, with certain exceptions permitted by applicable regulations. The Fund maintains a dollar-weighted average portfolio maturity of no more than 60 calendar days, and a dollar-weighted average life to maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a-7 under the Investment Company Act of 1940, as amended (Rule 2a-7), of no more than 60 calendar days. The Fund will limit investments to those securities that are Eligible Securities as defined by applicable regulations at the time of purchase. Eligible Securities are (i) Government Securities, (ii) shares of other money market funds, or (iii) securities determined to present minimal credit risks by Invesco Advisers, Inc. (Invesco or the Adviser) pursuant to guidelines approved by the Fund's Board of Trustees (the Board). Government Security generally means any securities issued or guaranteed as to principal or interest by the United States, or by a person controlled or supervised by and acting as an instrumentality of the government of the United States.

The Fund may invest in U.S. dollar-denominated foreign securities. Some of the Fund’s investments, although U.S. dollar-denominated, may be subject to foreign credit exposure.

The Fund may also invest in daily and weekly variable-rate demand notes.

The Fund may invest in securities that are subject to resale restrictions such as those contained in Rule 144A promulgated under the Securities Act of 1933, as amended.

In selecting securities for the Fund’s portfolio, the portfolio managers focus on securities that offer safety, liquidity, and a competitive yield.

Principal Risks of Investing in the Fund

As with any mutual fund investment, loss of money is a risk of investing. An investment in the Fund is not a bank account and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The risks associated with an investment in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are:

Money Market Fund Risk. You could lose money by investing in the Fund. Because the share price of the Fund will fluctuate, when you sell your shares they may be worth more or less than what you originally paid for them. The Fund may impose a fee upon the sale of your shares. Effective October 2, 2024, the Fund generally must impose a fee when net sales of Fund shares exceed certain levels. The Fund’s sponsor is not required to reimburse the Fund for losses, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial support to the Fund at any time, including during periods of market stress. The credit quality of the Fund’s holdings can change rapidly in certain markets, and the default of a single holding could have an adverse impact on the Fund’s share price. The Fund’s share price can also be negatively affected during periods of high redemption pressures, illiquid markets, and/or significant market volatility. Furthermore, the SEC recently adopted amendments to money market fund regulations that, when fully implemented, could impact the Fund’s operations, performance, yields and operating expenses.

Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a timely manner. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.

Changing Fixed Income Market Conditions Risk. Increases in the federal funds and equivalent foreign rates or other changes to monetary policy or regulatory actions may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. It is difficult to predict the impact of interest rate changes on various markets. In addition, decreases in fixed income dealer market-making capacity may also potentially lead to heightened volatility and reduced liquidity in the fixed income markets. As a result, the value of the Fund’s investments and share price may decline. Changes in central bank policies could also result in higher than normal

Principal Investment Strategies of the Fund

The Fund primarily invests its assets in U.S. Treasury Obligations backed by full faith and credit of the U.S. government maturing within 397 calendar days of the date of purchase, with certain exceptions permitted by applicable regulations, and repurchase agreements fully collateralized by U.S. Treasury Obligations.

The Fund is a Government Money Market Fund, as defined by Rule 2a-7 under the Investment Company Act of 1940, as amended (Rule 2a-7), that seeks to maintain a stable price of $1.00 per share by using the amortized cost method to value portfolio securities and rounding the share value to the nearest cent. The Fund invests at least 99.5% of its total assets in cash, Government Securities, and repurchase agreements collateralized by cash or Government Securities. Government Security generally means any securities issued or guaranteed as to principal or interest by the United States, or by a person controlled or supervised by and acting as an instrumentality of the government of the United States. The Fund considers repurchase agreements with the Federal Reserve Bank of New York to be U.S. government securities for purposes of the Fund’s investment policies.

The Fund’s sponsor is not required to reimburse the Fund for losses, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial support to the Fund or maintain the Fund’s $1.00 share price at any time, including during periods of market stress.

(Invesco or the Adviser) has contractually agreed to waive advisory fees and/or reimburse expenses to the extent necessary to limit Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement (excluding certain items discussed in the SAI) of Cash Management Class shares to 0.26%, of the Fund's average daily net assets (the “expense limit”). Unless Invesco continues the fee waiver agreement, it will terminate on December 31, 2024. During its term, the fee waiver agreement cannot be terminated or amended to increase the expense limit without approval of the Board of Trustees.

Example. This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain equal to the Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement in the first year and the Total Annual Fund Operating Expenses thereafter.

Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

 

	1 Year	3 Years	5 Years	10 Years
Cash Management Class	$27	$88	$155	$354

Principal Investment Strategies of the Fund

The Fund primarily invests its assets in U.S. Treasury Obligations backed by full faith and credit of the U.S. government maturing within 397 calendar days of the date of purchase, with certain exceptions permitted by applicable regulations.

The Fund also seeks to distribute dividends that are exempt from state and local taxation in many states.

The Fund is a Government Money Market Fund, as defined by Rule 2a-7 under the Investment Company Act of 1940, as amended (Rule 2a-7), that seeks to maintain a stable price of $1.00 per share by using the amortized cost method to value portfolio securities and rounding the share value to the nearest cent. The Fund invests at least 99.5% of its total assets in cash and Government Securities. Government Security generally means any securities issued or guaranteed as to principal or interest by the United States, or by a person controlled or supervised by and acting as an instrumentality of the government of the United States.

The Fund invests in conformity with U.S. Securities and Exchange Commission (SEC) rules and regulation requirements for money market funds for the quality, maturity, diversification and liquidity of investments.

Principal Risks of Investing in the Fund

As with any mutual fund investment, loss of money is a risk of investing. An investment in the Fund is not a bank account and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The risks associated with an investment in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are:

Money Market Fund Risk. You could lose money 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 share price of money market funds can fall below the $1.00 share price. The Fund’s sponsor is not required to reimburse the Fund for losses, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial support to the Fund or maintain the Fund’s $1.00 share price at any time, including during periods of market stress. The credit quality of the Fund’s holdings can change rapidly in certain markets, and the default of a single holding could have an adverse impact on the Fund’s share price. The Fund’s share price can also be negatively affected during periods of high redemption pressures, illiquid markets, and/or significant market volatility. Furthermore, the SEC recently adopted amendments to money market fund regulations that, when fully implemented, could impact the Fund’s operations, performance, yields and operating expenses.

Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a timely manner. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The Adviser’s credit analysis may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.

Changing Fixed Income Market Conditions Risk. Increases in the federal funds and equivalent foreign rates or other changes to monetary policy or regulatory actions may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. It is difficult to predict the impact of interest rate changes on various markets. In addition, decreases in fixed

Performance Information

The bar chart and performance table provide an indication of the risks of investing in the Fund. The bar chart shows changes in the performance of the Fund from year to year as of December 31. The Fund's past performance is not necessarily an indication of its future performance. Fund performance reflects any applicable fee waivers and expense reimbursements. Performance returns would be lower without applicable fee waivers and expense reimbursements. Updated performance information is available on the Fund's website at www.invesco.com/us.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund, the Fund’s distributor or its related companies may pay the intermediary for the sale of Fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson or financial adviser to recommend the Fund over another investment.
