The days to maturity for WAL is the lower of the stated maturity date or next demand feature date. WAL reflects how a portfolio would react to deteriorating credit (widening spreads) or tightening liquidity conditions.

Notes to Financial Statements

February 28, 2022

(Unaudited)

NOTE 1–Significant Accounting Policies

AIM Treasurer’s Series Trust (Invesco Treasurer’s Series Trust) (the “Trust”) is registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as an open-end series diversified management investment company. The Trust is organized as a Delaware statutory trust. The Funds covered in this report are Invesco Premier Portfolio and Invesco Premier U.S. Government Money Portfolio (collectively, the “Funds”). The assets, liabilities and operations of each portfolio are accounted for separately. Information presented in these financial statements pertains only to the Funds. Matters affecting each Fund or class will be voted on exclusively by the shareholders of such portfolio or class.

Invesco Premier Portfolio’s investment objective is to provide current income consistent with preservation of capital and liquidity. Invesco Premier U.S. Government Money Portfolio’s investment objective is a high level of current income consistent with the preservation of capital and the maintenance of liquidity.

Invesco Premier Portfolio currently consists of six classes of shares: Investor Class, Institutional Class, Private Investment Class, Personal Investment Class, Reserve Class and Resource Class. Invesco Premier U.S. Government Money Portfolio currently consists of two classes of shares: Investor Class and Institutional Class. Investor Class shares of the Funds are available only to certain investors. Each class of shares is sold at net asset value.

Each Fund is an investment company and accordingly follows the investment company accounting and reporting guidance in accordance with Financial Accounting Standards Board Accounting Standards Codification Topic 946, Financial Services — Investment Companies.

Invesco Premier Portfolio, a “retail money market fund” as defined in Rule 2a-7 under the 1940 Act, and Invesco Premier U.S. Government Portfolio, a “government money market fund” as defined in Rule 2a-7 under the 1940 Act, seek to maintain a stable or constant NAV of $1.00 per share using an amortized cost method of valuation.

“Retail money market funds” are required to adopt policies and procedures reasonably designed to limit investments in the Fund to accounts beneficially owned by natural persons. “Government money market funds” are required to invest at least 99.5% of their total assets in cash, Government Securities (as defined in the 1940 Act), and/or repurchase agreements collateralized fully by cash or Government Securities.

Invesco Premier Portfolio may impose a fee upon the sale of shares or may temporarily suspend the ability to sell shares if the Fund’s liquidity falls below required minimums or because of market conditions or other factors. The Board of Trustees has elected not to subject Invesco Premier U.S. Government Portfolio to liquidity fee and redemption gate requirements at this time, as permitted by Rule 2a-7.

The following is a summary of the significant accounting policies followed by the Funds in the preparation of their financial statements.

A. Security Valuations - Each Fund’s securities are recorded on the basis of amortized cost which approximates value as permitted by Rule 2a-7 under the 1940 Act. This method values a security at its cost on the date of purchase and, thereafter, assumes a constant amortization to maturity of any premiums or accretion of any discounts.

Because of the inherent uncertainties of valuation, the values reflected in the financial statements may materially differ from the value received upon actual sale of those investments.

Each Fund may invest in securities that are subject to interest rate risk, meaning the risk that the prices will generally fall as interest rates rise and, conversely, the prices will generally rise as interest rates fall. Specific securities differ in their sensitivity to changes in interest rates depending on their individual characteristics. Changes in interest rates may result in increased market volatility, which may affect the value and/ or liquidity of certain of each Fund’s investments.

B. Securities Transactions and Investment Income - Securities transactions are accounted for on a trade date basis. Realized gains or losses on sales are computed on the basis of specific identification of the securities sold. Interest income (net of withholding tax, if any) is recorded on the accrual basis from settlement date and includes coupon interest and amortization of premium and accretion of discount on debt securities as applicable.

The Funds may periodically participate in litigation related to each Fund’s investments. As such, the Funds may receive proceeds from litigation settlements involving each Fund’s investments. Any proceeds received are included in the Statements of Operations as realized gain (loss) for investments no longer held and as unrealized gain (loss) for investments still held.

Brokerage commissions and mark ups are considered transaction costs and are recorded as an increase to the cost basis of securities purchased and/or a reduction of proceeds on a sale of securities. Such transaction costs are included in the determination of net realized gain (loss) from investment securities reported in the Statements of Operations and the Statements of Changes in Net Assets and the net realized gains (losses) on securities per share in the Financial Highlights. Transaction costs are included in the calculation of each Fund’s net asset value and, accordingly, they reduce each Fund’s total returns. These transaction costs are not considered operating expenses and are not reflected in net investment income reported in the Statements of Operations and the Statements of Changes in Net Assets, or the net investment income per share and the ratios of expenses and net investment income reported in the Financial Highlights, nor are they limited by any expense limitation arrangements between the Funds and the investment adviser.

The Funds allocate realized capital gains and losses to a class based on the relative net assets of each class. The Funds allocate income to a class based on the relative value of the settled shares of each class.

C. Country Determination - For the purposes of making investment selection decisions and presentation in the Schedule of Investments, the investment adviser may determine the country in which an issuer is located and/or credit risk exposure based on various factors. These factors include the laws of the country under which the issuer is organized, where the issuer maintains a principal office, the country in which the issuer derives 50% or more of its total revenues and the country that has the primary market for the issuer’s securities, as well as other criteria. Among the other criteria that may be evaluated for making this determination are the country in which the issuer maintains 50% or more of its assets, the type of security, financial guarantees and enhancements, the nature of the collateral and the sponsor organization. Country of issuer and/or credit risk exposure has been determined to be the United States of America, unless otherwise noted.

D. Distributions - It is the policy of the Funds to declare dividends from net investment income daily and pay dividends on the first business day of the following month. Each Fund generally distributes net realized capital gain (including net short-term capital gain), if any, annually.

16 AIM Treasurer’s Series Trust (Invesco Treasurer’s Series Trust)

E. Federal Income Taxes - The Funds intend to comply with the requirements of Subchapter M of the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), necessary to qualify as a regulated investment company and to distribute substantially all of the Funds’ taxable earnings to shareholders. As such, the Funds will not be subject to federal income taxes on otherwise taxable income (including net realized capital gain) that is distributed to shareholders. Therefore, no provision for federal income taxes is recorded in the financial statements.

The Funds recognize the tax benefits of uncertain tax positions only when the position is more likely than not to be sustained. Management has analyzed each Fund’s uncertain tax positions and concluded that no liability for unrecognized tax benefits should be recorded related to uncertain tax positions. Management is not aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will change materially in the next 12 months.

Each Fund files tax returns in the U.S. Federal jurisdiction and certain other jurisdictions. Generally, each Fund is subject to examinations by such taxing authorities for up to three years after the filing of the return for the tax period.

F. Expenses - Fees provided for under the Rule 12b-1 plan of a particular class of each Fund and which are directly attributable to that class are charged to the operations of such class. All other expenses are allocated among the classes based on relative net assets.

G. Accounting Estimates - The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period including estimates and assumptions related to taxation. Actual results could differ from those estimates by a significant amount. In addition, each Fund monitors for material events or transactions that may occur or become known after the period-end date and before the date the financial statements are released to print.

H. Indemnifications - Under the Trust’s organizational documents, each Trustee, officer, employee or other agent of the Trust is indemnified against certain liabilities that may arise out of the performance of their duties to the Funds. Additionally, in the normal course of business, the Funds enter into contracts, including each Fund’s servicing agreements, that contain a variety of indemnification clauses. Each Fund’s maximum exposure under these arrangements is unknown as this would involve future claims that may be made against such Fund that have not yet occurred. The risk of material loss as a result of such indemnification claims is considered remote.

I. Repurchase Agreements - The Funds may enter into repurchase agreements. Collateral on repurchase agreements, including each Fund’s pro-rata interest in joint repurchase agreements, is taken into possession by such Funds upon entering into the repurchase agreement. Collateral consisting of U.S. Government Securities and U.S. Government Sponsored Agency Securities is marked to market daily to ensure its market value is at least 102% of the sales price of the repurchase agreement. Collateral consisting of non-government securities is marked to market daily to ensure its market value is at least 105% of the sales price of the repurchase agreement. The investments in some repurchase agreements, pursuant to procedures approved by the Board of Trustees, are through participation with other mutual funds, private accounts and certain non-registered investment companies managed by the investment advisor or its affiliates (“Joint repurchase agreements”). The principal amount of the repurchase agreement is equal to the value at period-end. If the seller of a repurchase agreement fails to repurchase the security in accordance with the terms of the agreement, the Funds might incur expenses in enforcing their rights, and could experience losses, including a decline in the value of the collateral and loss of income.

J. Other Risks - Investments in obligations issued by agencies and instrumentalities of the U.S. Government may vary in the level of support they receive from the government. The government may choose not to provide financial support to government sponsored agencies or instrumentalities if it is not legally obligated to do so. In this case, if the issuer defaulted, the Funds may not be able to recover its investment in such issuer from the U.S. Government. Additionally, from time to time, uncertainty regarding the status of negotiations in the U.S. Government to increase the statutory debt limit, commonly called the “debt ceiling”, could increase the risk that the U.S. Government may default on payments on certain U.S. Government securities, cause the credit rating of the U.S. Government to be downgraded, increase volatility in the stock and bond markets, result in higher interest rates, reduce prices of U.S. Treasury securities, and/or increase the costs of various kinds of debt. If a U.S. Government-sponsored entity is negatively impacted by legislative or regulatory action, is unable to meet its obligations, or its creditworthiness declines, the performance of each Fund that holds securities of that entity will be adversely impacted.

The effect on performance from investing in securities issued or guaranteed by companies in the banking and financial services industries will depend to a greater extent on the overall condition of those industries. Financial services companies are highly dependent on the supply of short-term financing. The value of securities of issuers in the banking and financial services industry can be sensitive to changes in government regulation and interest rates and to economic downturns in the United States and abroad.

U.S. dollar-denominated securities carrying foreign credit exposure may be affected by unfavorable political, economic or governmental developments that could affect payments of principal and interest.

K. COVID-19 Risk - The COVID-19 strain of coronavirus has resulted in instances of market closures and dislocations, extreme volatility, liquidity constraints and increased trading costs. Efforts to contain its spread have resulted in travel restrictions, disruptions of healthcare systems, business operations (including business closures) and supply chains, layoffs, lower consumer demand and employee availability, and defaults and credit downgrades, among other significant economic impacts that have disrupted global economic activity across many industries. Such economic impacts may exacerbate other pre-existing political, social and economic risks locally or globally and cause general concern and uncertainty.

The full economic impact and ongoing effects of COVID-19 (or other future epidemics or pandemics) at the macro-level and on individual businesses are unpredictable and may result in significant and prolonged effects on the Funds’ performance.

NOTE 2–Advisory Fees and Other Fees Paid to Affiliates

The Trust has entered into a master investment advisory agreement with Invesco Advisers, Inc. (the “Adviser” or “Invesco”). Under the terms of the investment advisory agreement, each Fund accrues daily and pays monthly an advisory fee to the Adviser at an annual rate of 0.25% of such Fund’s average daily net assets. Pursuant to the master investment advisory agreement, the Adviser bears all expenses incurred by each Fund in connection with its operations, except for (1) interest, taxes and extraordinary items such as litigation costs; (2) brokers’ commissions, issue and transfer taxes, and other costs chargeable to each Fund in connection with securities transactions to which such Fund is a party or in connection with securities owned by such Fund; and (3) other expenditures which are capitalized in accordance with generally accepted accounting principles applicable to investment companies.

17 AIM Treasurer’s Series Trust (Invesco Treasurer’s Series Trust)

Under the terms of a master sub-advisory agreement between the Adviser to Invesco Premier Portfolio and each of Invesco Asset Management Deutschland GmbH, Invesco Asset Management Limited, Invesco Asset Management (Japan) Limited, Invesco Hong Kong Limited, Inc., Invesco Senior Secured Management, Inc. and Invesco Canada Ltd. and separate sub-advisory agreements with Invesco Capital Management LLC and Invesco Asset Management (India) Private Limited (collectively, the “Affiliated Sub-Advisers”) the Adviser, not the Fund, will pay 40% of the fees paid to the Adviser to any such Affiliated Sub-Adviser(s) that provide(s) discretionary investment management services to the Fund based on the percentage of assets allocated to such Sub-Adviser(s).

The Adviser has contractually agreed, through at least December 31, 2022, to waive advisory fees equal to 0.07% of the average daily net assets of Invesco Premier Portfolio and Invesco Premier U.S. Government Money Portfolio.

For the six months ended February 28, 2022, the Adviser waived advisory fees and/or reimbursed Fund expenses in the following amounts:

Invesco Premier Portfolio	$	394,901
Invesco Premier U.S. Government Money Portfolio		1,935,730

Further, Invesco and/or Invesco Distributors, Inc. (“IDI”) voluntarily waived fees and/or reimbursed expenses in order to increase the yields of each Fund. Voluntary fee waivers and/or reimbursements may be modified or discontinued at any time upon consultation with the Board of Trustees without further notice to investors. Voluntary fee waivers for the six months ended February 28, 2022 are shown below:

			Private	Personal
			Investment	Investment	Reserve	Resource
	Fund Level		Class	Class	Class	Class
Invesco Premier Portfolio	$	45,340	$187	$22,229	$45	$	2,447
Invesco Premier U.S. Government Money Portfolio		2,728,901	-	-	-		-

The Trust has entered into a master administrative services agreement with Invesco to provide accounting services to each Fund. The Trust has also entered into a transfer agency and service agreement with Invesco Investment Services, Inc. (“IIS”) to provide transfer agency and shareholder services to each Fund. Invesco and IIS do not charge the Funds any fees under these agreements. Also, Invesco has entered into a sub-administration agreement whereby The Bank of New York Mellon (“BNY Mellon”) serves as fund accountant and provides certain administrative services to the Funds. Pursuant to a custody agreement with the Trust on behalf of the Funds, BNY Mellon also serves as the Funds’ custodian.

The Trust has entered into master distribution agreements with IDI to serve as the distributor for the Investor Class, Institutional Class, Personal Investment Class, Private Investment Class, Reserve Class and Resource Class shares. The Trust has adopted plans pursuant to Rule 12b-1 under the 1940 Act with respect to Invesco Premier Portfolio’s Personal Investment Class, Private Investment Class, Reserve Class and Resource Class shares (collectively, the “Plans”). The Fund, pursuant to the Plans, pays IDI compensation at the annual rate of 0.55% of the Fund’s average daily net assets of Personal Investment Class shares, 0.30% of the average daily net assets of Private Investment Class shares, 0.87% of the average daily net assets of Reserve Class shares and 0.16% of the average daily net assets of Resource Class shares. The fees are accrued daily and paid monthly. Of the Plan payments, up to 0.25% of the average daily net assets of each class of shares may be paid to furnish continuing personal shareholder services to customers who purchase and own shares of such class. Any amounts not paid as a service fee under the Plans would constitute an asset-based sales charge. Rules of the Financial Industry Regulatory Authority (“FINRA”) impose a cap on the total sales charges, including asset-based sales charges, that may be paid by any class of shares of the Fund. For the six months ended February 28, 2022, expenses incurred under the plans are shown in the Statement of Operations as Distribution fees.

Certain officers and trustees of the Trust are officers and directors of the Adviser, IIS and/or IDI.

NOTE 3–Additional Valuation Information

GAAP defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date, under current market conditions. GAAP establishes a hierarchy that prioritizes the inputs to valuation methods, giving the highest priority to readily available unadjusted quoted prices in an active market for identical assets (Level 1) and the lowest priority to significant unobservable inputs (Level 3), generally when market prices are not readily available or are unreliable. Based on the valuation inputs, the securities or other investments are tiered into one of three levels. Changes in valuation methods may result in transfers in or out of an investment’s assigned level:

Level 1	– Prices are determined using quoted prices in an active market for identical assets.
Level 2	– Prices are determined using other significant observable inputs. Observable inputs are inputs that other market participants may use in pricing a security. These may include quoted prices for similar securities, interest rates, prepayment speeds, credit risk, yield curves, loss severities, default rates, discount rates, volatilities and others.
Level 3	– Prices are determined using significant unobservable inputs. In situations where quoted prices or observable inputs are unavailable (for example, when there is little or no market activity for an investment at the end of the period), unobservable inputs may be used. Unobservable inputs reflect each Fund’s own assumptions about the factors market participants would use in determining fair value of the securities or instruments and would be based on the best available information.

As of February 28, 2022, all of the securities in each Fund were valued based on Level 2 inputs (see the Schedule of Investments for security categories). The level assigned to the securities valuations may not be an indication of the risk or liquidity associated with investing in those securities. Because of the inherent uncertainties of valuation, the values reflected in the financial statements may materially differ from the value received upon actual sale of those investments.

NOTE 4–Security Transactions with Affiliated Funds

Each Fund is permitted to purchase or sell securities from or to certain other Invesco Funds under specified conditions outlined in procedures adopted by the Board of Trustees of the Trust. The procedures have been designed to ensure that any purchase or sale of securities by each Fund from or to another fund or portfolio that is or could be considered an affiliate by virtue of having a common investment adviser (or affiliated investment

18 AIM Treasurer’s Series Trust (Invesco Treasurer’s Series Trust)

advisers), common Trustees and/or common officers complies with Rule 17a-7 of the 1940 Act. Further, as defined under the procedures, each transaction is effected at the current market price. For the six months ended February 28, 2022, each Fund engaged in transactions with affiliates as listed below:

	Securities Purchases	Securities Sales	Net Realized Gains
Invesco Premier Portfolio	$115,591,084	$84,848,987	$-

NOTE 5–Trustees’ and Officers’ Fees and Benefits

Remuneration is paid to certain Trustees and Officers of the Trust. Trustees have the option to defer their compensation. Those Trustees who defer compensation have the option to select various Invesco Funds in which their deferral accounts shall be deemed to be invested.

    Certain current Trustees were eligible to participate in a retirement plan that provided for benefits to be paid upon retirement to Trustees over a period of time based on the number of years of service. The Funds may have certain former Trustees that also participate in a retirement plan and receive benefits under such plan. Each Fund’s allocable portion of the remuneration paid to the Trustees, including its allocable portion of the fees and benefits of the deferred compensation plan and retirement plan are paid by Invesco and not by the Trust.

NOTE 6–Cash Balances

The Funds are permitted to temporarily overdraft or leave balances in their accounts with BNY Mellon, the custodian bank. Such balances, if any at period-end, are shown in the Statements of Assets and Liabilities under the payable caption Amount due custodian. To compensate BNY Mellon or the Funds for such activity, the Funds may either (1) pay to or receive from BNY Mellon compensation at a rate agreed upon by BNY Mellon and Invesco, not to exceed the contractually agreed upon rate; or (2) leave funds or overdraft funds as a compensating balance in the account so BNY Mellon or the Funds can be compensated for use of funds.

NOTE 7–Tax Information

The amount and character of income and gains to be distributed are determined in accordance with income tax regulations, which may differ from GAAP. Reclassifications are made to each Fund’s capital accounts to reflect income and gains available for distribution (or available capital loss carryforward) under income tax regulations. The tax character of distributions paid during the year and the tax components of net assets will be reported at each Fund’s fiscal year-end.

Capital loss carryforward is calculated and reported as of a specific date. Results of transactions and other activity after that date may affect the amount of capital loss carryforward actually available for the Funds to utilize. The ability to utilize capital loss carryforwards in the future may be limited under the Internal Revenue Code and related regulations based on the results of future transactions.

The Funds did not have any capital loss carryforward as of August 31, 2021.

Calculating your ongoing Fund expenses

Example

As a shareholder in the Investor Class, you incur ongoing costs, such as management fees. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Funds and to compare these costs with ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period September 1, 2021 through February 28, 2022.

Actual expenses

The table below provides information about actual account values and actual expenses. You may use the information in this table, together with the amount you invested, to estimate the expenses that you paid over the period. 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 in the table under the heading entitled “Actual Expenses Paid During Period” to estimate the expenses you paid on your account during this period.

Hypothetical example for comparison purposes

The table below also provides information about hypothetical account values and hypothetical expenses based on each Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not each Fund’s actual return.

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 the Funds 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. Therefore, the hypothetical information is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds.

		ACTUAL		HYPOTHETICAL (5% annual return before expenses)
	Beginning	Ending	Expenses	Ending	Expenses	Annualized
	Account Value	Account Value	Paid During	Account Value	Paid During	Expense

¹  The actual ending account value is based on the actual total return of the Funds for the period September 1, 2021 through February 28, 2022, after actual expenses and will differ from the hypothetical ending account value which is based on each Fund’s expense ratio and a hypothetical annual return of 5% before expenses.

²  Expenses are equal to each Fund’s annualized expense ratio as indicated above multiplied by the average account value over the period, multiplied by 181/365 to reflect the most recent fiscal half year.

Notes to Financial Statements

February 28, 2022

(Unaudited)

NOTE 1–Significant Accounting Policies

AIM Treasurer’s Series Trust (Invesco Treasurer’s Series Trust) (the “Trust”) is registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as an open-end series diversified management investment company. The Trust is organized as a Delaware statutory trust. The Funds covered in this report are Invesco Premier Portfolio and Invesco Premier U.S. Government Money Portfolio (collectively, the “Funds”). The assets, liabilities and operations of each portfolio are accounted for separately. Information presented in these financial statements pertains only to the Funds. Matters affecting each Fund or class will be voted on exclusively by the shareholders of such portfolio or class.

    Invesco Premier Portfolio’s investment objective is to provide current income consistent with preservation of capital and liquidity. Invesco Premier U.S. Government Money Portfolio’s investment objective is a high level of current income consistent with the preservation of capital and the maintenance of liquidity.

    Invesco Premier Portfolio currently consists of six classes of shares: Investor Class, Institutional Class, Private Investment Class, Personal Investment Class, Reserve Class and Resource Class. Invesco Premier U.S. Government Money Portfolio currently consists of two classes of shares: Investor Class and Institutional Class. Investor Class shares of the Funds are available only to certain investors. Each class of shares is sold at net asset value.

    Each Fund is an investment company and accordingly follows the investment company accounting and reporting guidance in accordance with Financial Accounting Standards Board Accounting Standards Codification Topic 946, Financial Services – Investment Companies.

    Invesco Premier Portfolio, a “retail money market fund” as defined in Rule 2a-7 under the 1940 Act, and Invesco Premier U.S. Government Portfolio, a “government money market fund” as defined in Rule 2a-7 under the 1940 Act, seek to maintain a stable or constant NAV of $1.00 per share using an amortized cost method of valuation.

    “Retail money market funds” are required to adopt policies and procedures reasonably designed to limit investments in the Fund to accounts beneficially owned by natural persons. “Government money market funds” are required to invest at least 99.5% of their total assets in cash, Government Securities (as defined in the 1940 Act), and/or repurchase agreements collateralized fully by cash or Government Securities.

    Invesco Premier Portfolio may impose a fee upon the sale of shares or may temporarily suspend the ability to sell shares if the Fund’s liquidity falls below required minimums or because of market conditions or other factors. The Board of Trustees has elected not to subject Invesco Premier U.S. Government Portfolio to liquidity fee and redemption gate requirements at this time, as permitted by Rule 2a-7.

    The following is a summary of the significant accounting policies followed by the Funds in the preparation of their financial statements.

A. Security Valuations – Each Fund’s securities are recorded on the basis of amortized cost which approximates value as permitted by Rule 2a-7 under the 1940 Act. This method values a security at its cost on the date of purchase and, thereafter, assumes a constant amortization to maturity of any premiums or accretion of any discounts.

Because of the inherent uncertainties of valuation, the values reflected in the financial statements may materially differ from the value received upon actual sale of those investments.

Each Fund may invest in securities that are subject to interest rate risk, meaning the risk that the prices will generally fall as interest rates rise and, conversely, the prices will generally rise as interest rates fall. Specific securities differ in their sensitivity to changes in interest rates depending on their individual characteristics. Changes in interest rates may result in increased market volatility, which may affect the value and/ or liquidity of certain of each Fund’s investments.

B. Securities Transactions and Investment Income – Securities transactions are accounted for on a trade date basis. Realized gains or losses on sales are computed on the basis of specific identification of the securities sold. Interest income (net of withholding tax, if any) is recorded on the accrual basis from settlement date and includes coupon interest and amortization of premium and accretion of discount on debt securities as applicable.

The Funds may periodically participate in litigation related to each Fund’s investments. As such, the Funds may receive proceeds from litigation settlements involving each Fund’s investments. Any proceeds received are included in the Statements of Operations as realized gain (loss) for investments no longer held and as unrealized gain (loss) for investments still held.

Brokerage commissions and mark ups are considered transaction costs and are recorded as an increase to the cost basis of securities purchased and/or a reduction of proceeds on a sale of securities. Such transaction costs are included in the determination of net realized gain (loss) from investment securities reported in the Statements of Operations and the Statements of Changes in Net Assets and the net realized gains (losses) on securities per share in the Financial Highlights. Transaction costs are included in the calculation of each Fund’s net asset value and, accordingly, they reduce each Fund’s total returns. These transaction costs are not considered operating expenses and are not reflected in net investment income reported in the Statements of Operations and the Statements of Changes in Net Assets, or the net investment income per share and the ratios of expenses and net investment income reported in the Financial Highlights, nor are they limited by any expense limitation arrangements between the Funds and the investment adviser.

The Funds allocate realized capital gains and losses to a class based on the relative net assets of each class. The Funds allocate income to a class based on the relative value of the settled shares of each class.

C. Country Determination - For the purposes of making investment selection decisions and presentation in the Schedule of Investments, the investment adviser may determine the country in which an issuer is located and/or credit risk exposure based on various factors. These factors include the laws of the country under which the issuer is organized, where the issuer maintains a principal office, the country in which the issuer derives 50% or more of its total revenues and the country that has the primary market for the issuer’s securities, as well as other criteria. Among the other criteria that may be evaluated for making this determination are the country in which the issuer maintains 50% or more of its assets, the type of security, financial guarantees and enhancements, the nature of the collateral and the sponsor organization. Country of issuer and/or credit risk exposure has been determined to be the United States of America, unless otherwise noted.

D. Distributions - It is the policy of the Funds to declare dividends from net investment income daily and pay dividends on the first business day of the following month. Each Fund generally distributes net realized capital gain (including net short-term capital gain), if any, annually.

16 AIM Treasurer’s Series Trust (Invesco Treasurer’s Series Trust)

E. Federal Income Taxes – The Funds intend to comply with the requirements of Subchapter M of the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), necessary to qualify as a regulated investment company and to distribute substantially all of the Funds’ taxable earnings to shareholders. As such, the Funds will not be subject to federal income taxes on otherwise taxable income (including net realized capital gain) that is distributed to shareholders. Therefore, no provision for federal income taxes is recorded in the financial statements.

The Funds recognize the tax benefits of uncertain tax positions only when the position is more likely than not to be sustained. Management has analyzed each Fund’s uncertain tax positions and concluded that no liability for unrecognized tax benefits should be recorded related to uncertain tax positions. Management is not aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will change materially in the next 12 months.

Each Fund files tax returns in the U.S. Federal jurisdiction and certain other jurisdictions. Generally, each Fund is subject to examinations by such taxing authorities for up to three years after the filing of the return for the tax period.

F. Expenses – Fees provided for under the Rule 12b-1 plan of a particular class of each Fund and which are directly attributable to that class are charged to the operations of such class. All other expenses are allocated among the classes based on relative net assets.

G. Accounting Estimates – The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period including estimates and assumptions related to taxation. Actual results could differ from those estimates by a significant amount. In addition, each Fund monitors for material events or transactions that may occur or become known after the period-end date and before the date the financial statements are released to print.

H. Indemnifications – Under the Trust’s organizational documents, each Trustee, officer, employee or other agent of the Trust is indemnified against certain liabilities that may arise out of the performance of their duties to the Funds. Additionally, in the normal course of business, the Funds enter into contracts, including each Fund’s servicing agreements, that contain a variety of indemnification clauses. Each Fund’s maximum exposure under these arrangements is unknown as this would involve future claims that may be made against such Fund that have not yet occurred. The risk of material loss as a result of such indemnification claims is considered remote.

I. Repurchase Agreements – The Funds may enter into repurchase agreements. Collateral on repurchase agreements, including each Fund’s pro-rata interest in joint repurchase agreements, is taken into possession by such Funds upon entering into the repurchase agreement. Collateral consisting of U.S. Government Securities and U.S. Government Sponsored Agency Securities is marked to market daily to ensure its market value is at least 102% of the sales price of the repurchase agreement. Collateral consisting of non-government securities is marked to market daily to ensure its market value is at least 105% of the sales price of the repurchase agreement. The investments in some repurchase agreements, pursuant to procedures approved by the Board of Trustees, are through participation with other mutual funds, private accounts and certain non-registered investment companies managed by the investment advisor or its affiliates (“Joint repurchase agreements”). The principal amount of the repurchase agreement is equal to the value at period-end. If the seller of a repurchase agreement fails to repurchase the security in accordance with the terms of the agreement, the Funds might incur expenses in enforcing their rights, and could experience losses, including a decline in the value of the collateral and loss of income.

J. Other Risks – Investments in obligations issued by agencies and instrumentalities of the U.S. Government may vary in the level of support they receive from the government. The government may choose not to provide financial support to government sponsored agencies or instrumentalities if it is not legally obligated to do so. In this case, if the issuer defaulted, the Funds may not be able to recover its investment in such issuer from the U.S. Government. Additionally, from time to time, uncertainty regarding the status of negotiations in the U.S. Government to increase the statutory debt limit, commonly called the “debt ceiling”, could increase the risk that the U.S. Government may default on payments on certain U.S. Government securities, cause the credit rating of the U.S. Government to be downgraded, increase volatility in the stock and bond markets, result in higher interest rates, reduce prices of U.S. Treasury securities, and/or increase the costs of various kinds of debt. If a U.S. Government-sponsored entity is negatively impacted by legislative or regulatory action, is unable to meet its obligations, or its creditworthiness declines, the performance of each Fund that holds securities of that entity will be adversely impacted.

The effect on performance from investing in securities issued or guaranteed by companies in the banking and financial services industries will depend to a greater extent on the overall condition of those industries. Financial services companies are highly dependent on the supply of short-term financing. The value of securities of issuers in the banking and financial services industry can be sensitive to changes in government regulation and interest rates and to economic downturns in the United States and abroad.

U.S. dollar-denominated securities carrying foreign credit exposure may be affected by unfavorable political, economic or governmental developments that could affect payments of principal and interest.

K. COVID-19 Risk – The COVID-19 strain of coronavirus has resulted in instances of market closures and dislocations, extreme volatility, liquidity constraints and increased trading costs. Efforts to contain its spread have resulted in travel restrictions, disruptions of healthcare systems, business operations (including business closures) and supply chains, layoffs, lower consumer demand and employee availability, and defaults and credit downgrades, among other significant economic impacts that have disrupted global economic activity across many industries. Such economic impacts may exacerbate other pre-existing political, social and economic risks locally or globally and cause general concern and uncertainty.

The full economic impact and ongoing effects of COVID-19 (or other future epidemics or pandemics) at the macro-level and on individual businesses are unpredictable and may result in significant and prolonged effects on the Funds’ performance.

NOTE 2–Advisory Fees and Other Fees Paid to Affiliates

The Trust has entered into a master investment advisory agreement with Invesco Advisers, Inc. (the “Adviser” or “Invesco”). Under the terms of the investment advisory agreement, each Fund accrues daily and pays monthly an advisory fee to the Adviser at an annual rate of 0.25% of such Fund’s average daily net assets. Pursuant to the master investment advisory agreement, the Adviser bears all expenses incurred by each Fund in connection with its operations, except for (1) interest, taxes and extraordinary items such as litigation costs; (2) brokers’ commissions, issue and transfer taxes, and other costs chargeable to each Fund in connection with securities transactions to which such Fund is a party or in connection with securities owned by such Fund; and (3) other expenditures which are capitalized in accordance with generally accepted accounting principles applicable to investment companies.

17 AIM Treasurer’s Series Trust (Invesco Treasurer’s Series Trust)

    Under the terms of a master sub-advisory agreement between the Adviser to Invesco Premier Portfolio and each of Invesco Asset Management Deutschland GmbH, Invesco Asset Management Limited, Invesco Asset Management (Japan) Limited, Invesco Hong Kong Limited, Inc., Invesco Senior Secured Management, Inc. and Invesco Canada Ltd. and separate sub-advisory agreements with Invesco Capital Management LLC and Invesco Asset Management (India) Private Limited (collectively, the “Affiliated Sub-Advisers”) the Adviser, not the Fund, will pay 40% of the fees paid to the Adviser to any such Affiliated Sub-Adviser(s) that provide(s) discretionary investment management services to the Fund based on the percentage of assets allocated to such Sub-Adviser(s).

    The Adviser has contractually agreed, through at least December 31, 2022, to waive advisory fees equal to 0.07% of the average daily net assets of Invesco Premier Portfolio and Invesco Premier U.S. Government Money Portfolio.

    For the six months ended February 28, 2022, the Adviser waived advisory fees and/or reimbursed Fund expenses in the following amounts:

Invesco Premier Portfolio	$	394,901
Invesco Premier U.S. Government Money Portfolio		1,935,730

    Further, Invesco and/or Invesco Distributors, Inc. (“IDI”) voluntarily waived fees and/or reimbursed expenses in order to increase the yields of each Fund. Voluntary fee waivers and/or reimbursements may be modified or discontinued at any time upon consultation with the Board of Trustees without further notice to investors. Voluntary fee waivers for the six months ended February 28, 2022 are shown below:

				Private			Personal
				Investment			Investment			Reserve			Resource
	Fund Level			Class			Class			Class			Class
Invesco Premier Portfolio		$	45,340		$	187		$	22,229		$	45		$	2,447
Invesco Premier U.S. Government Money Portfolio			2,728,901			-			-			-			-

    The Trust has entered into a master administrative services agreement with Invesco to provide accounting services to each Fund. The Trust has also entered into a transfer agency and service agreement with Invesco Investment Services, Inc. (“IIS”) to provide transfer agency and shareholder services to each Fund. Invesco and IIS do not charge the Funds any fees under these agreements. Also, Invesco has entered into a sub-administration agreement whereby The Bank of New York Mellon (“BNY Mellon”) serves as fund accountant and provides certain administrative services to the Funds. Pursuant to a custody agreement with the Trust on behalf of the Funds, BNY Mellon also serves as the Funds’ custodian.

    The Trust has entered into master distribution agreements with IDI to serve as the distributor for the Investor Class, Institutional Class, Personal Investment Class, Private Investment Class, Reserve Class and Resource Class shares. The Trust has adopted plans pursuant to Rule 12b-1 under the 1940 Act with respect to Invesco Premier Portfolio’s Personal Investment Class, Private Investment Class, Reserve Class and Resource Class shares (collectively, the “Plans”). The Fund, pursuant to the Plans, pays IDI compensation at the annual rate of 0.55% of the Fund’s average daily net assets of Personal Investment Class shares, 0.30% of the average daily net assets of Private Investment Class shares, 0.87% of the average daily net assets of Reserve Class shares and 0.16% of the average daily net assets of Resource Class shares. The fees are accrued daily and paid monthly. Of the Plan payments, up to 0.25% of the average daily net assets of each class of shares may be paid to furnish continuing personal shareholder services to customers who purchase and own shares of such class. Any amounts not paid as a service fee under the Plans would constitute an asset-based sales charge. Rules of the Financial Industry Regulatory Authority (“FINRA”) impose a cap on the total sales charges, including asset-based sales charges, that may be paid by any class of shares of the Fund. For the six months ended February 28, 2022, expenses incurred under the plans are shown in the Statement of Operations as Distribution fees.

    Certain officers and trustees of the Trust are officers and directors of the Adviser, IIS and/or IDI.

NOTE 3–Additional Valuation Information

GAAP defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date, under current market conditions. GAAP establishes a hierarchy that prioritizes the inputs to valuation methods, giving the highest priority to readily available unadjusted quoted prices in an active market for identical assets (Level 1) and the lowest priority to significant unobservable inputs (Level 3), generally when market prices are not readily available or are unreliable. Based on the valuation inputs, the securities or other investments are tiered into one of three levels. Changes in valuation methods may result in transfers in or out of an investment’s assigned level:

Level 1 – Prices are determined using quoted prices in an active market for identical assets.

Level 2 – Prices are determined using other significant observable inputs. Observable inputs are inputs that other market participants may use in pricing a security. These may include quoted prices for similar securities, interest rates, prepayment speeds, credit risk, yield curves, loss severities, default rates, discount rates, volatilities and others.

Level 3 – Prices are determined using significant unobservable inputs. In situations where quoted prices or observable inputs are unavailable (for example, when there is little or no market activity for an investment at the end of the period), unobservable inputs may be used. Unobservable inputs reflect each Fund’s own assumptions about the factors market participants would use in determining fair value of the securities or instruments and would be based on the best available information.

    As of February 28, 2022, all of the securities in each Fund were valued based on Level 2 inputs (see the Schedule of Investments for security categories). The level assigned to the securities valuations may not be an indication of the risk or liquidity associated with investing in those securities. Because of the inherent uncertainties of valuation, the values reflected in the financial statements may materially differ from the value received upon actual sale of those investments.

NOTE 4–Security Transactions with Affiliated Funds

Each Fund is permitted to purchase or sell securities from or to certain other Invesco Funds under specified conditions outlined in procedures adopted by the Board of Trustees of the Trust. The procedures have been designed to ensure that any purchase or sale of securities by each Fund from or to another fund or portfolio that is or could be considered an affiliate by virtue of having a common investment adviser (or affiliated investment

18 AIM Treasurer’s Series Trust (Invesco Treasurer’s Series Trust)

advisers), common Trustees and/or common officers complies with Rule 17a-7 of the 1940 Act. Further, as defined under the procedures, each transaction is effected at the current market price. For the six months ended February 28, 2022, each Fund engaged in transactions with affiliates as listed below:

	Securities Purchases			Securities Sales			Net Realized Gains
Invesco Premier Portfolio		$	115,591,084		$	84,848,987		$	-

NOTE 5–Trustees’ and Officers’ Fees and Benefits

Remuneration is paid to certain Trustees and Officers of the Trust. Trustees have the option to defer their compensation. Those Trustees who defer compensation have the option to select various Invesco Funds in which their deferral accounts shall be deemed to be invested.

    Certain current Trustees were eligible to participate in a retirement plan that provided for benefits to be paid upon retirement to Trustees over a period of time based on the number of years of service. The Funds may have certain former Trustees that also participate in a retirement plan and receive benefits under such plan. Each Fund’s allocable portion of the remuneration paid to the Trustees, including its allocable portion of the fees and benefits of the deferred compensation plan and retirement plan are paid by Invesco and not by the Trust.

NOTE 6–Cash Balances

The Funds are permitted to temporarily overdraft or leave balances in their accounts with BNY Mellon, the custodian bank. Such balances, if any at period-end, are shown in the Statements of Assets and Liabilities under the payable caption Amount due custodian. To compensate BNY Mellon or the Funds for such activity, the Funds may either (1) pay to or receive from BNY Mellon compensation at a rate agreed upon by BNY Mellon and Invesco, not to exceed the contractually agreed upon rate; or (2) leave funds or overdraft funds as a compensating balance in the account so BNY Mellon or the Funds can be compensated for use of funds.

NOTE 7–Tax Information

The amount and character of income and gains to be distributed are determined in accordance with income tax regulations, which may differ from GAAP. Reclassifications are made to each Fund’s capital accounts to reflect income and gains available for distribution (or available capital loss carryforward) under income tax regulations. The tax character of distributions paid during the year and the tax components of net assets will be reported at each Fund’s fiscal year-end.

    Capital loss carryforward is calculated and reported as of a specific date.

Calculating your ongoing Fund expenses

Example

As a shareholder in the Institutional Class, you incur ongoing costs, such as management fees. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Funds and to compare these costs with ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period September 1, 2021 through February 28, 2022.

Actual expenses

The table below provides information about actual account values and actual expenses. You may use the information in this table, together with the amount you invested, to estimate the expenses that you paid over the period. 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 in the table under the heading entitled “Actual Expenses Paid During Period” to estimate the expenses you paid on your account during this period.

Hypothetical example for comparison purposes

The table below also provides information about hypothetical account values and hypothetical expenses based on each Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not each Fund’s actual return.

    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 the Funds 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. Therefore, the hypothetical information is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds.

		ACTUAL		HYPOTHETICAL (5% annual return before expenses)
Institutional Class	Beginning     Account Value     (09/01/21)	Ending             Account Value              (02/28/22)1	Expenses         Paid During         Period2	Ending     Account Value     (02/28/22)	Expenses     Paid During     Period2	Annualized     Expense     Ratio
Invesco Premier Portfolio	$1,000.00	$1,000.10	$0.84	$1,023.95	$0.85	0.17%
Invesco Premier U.S. Government Money Portfolio	1,000.00	1,000.10	0.40	1,024.40	0.40	0.08

¹  The actual ending account value is based on the actual total return of the Funds for the period September 1, 2021 through February 28, 2022, after actual expenses and will differ from the hypothetical ending account value which is based on each Fund’s expense ratio and a hypothetical annual return of 5% before expenses.

²  Expenses are equal to each Fund’s annualized expense ratio as indicated above multiplied by the average account value over the period, multiplied by 181/365 to reflect the most recent fiscal half year.

The days to maturity for WAM is the lower of the stated maturity date or next interest rate reset date. WAM reflects how a portfolio would react to interest rate changes.
Weighted average life (WAL) is an average of all the maturities of all securities held in the portfolio, weighted by each security’s percentage of net assets. The days to maturity for WAL is the lower of the stated maturity date or next demand feature date. WAL reflects how a portfolio would react to deteriorating credit (widening spreads) or tightening liquidity conditions.

Notes to Financial Statements

February 28, 2022

(Unaudited)

NOTE 1–Significant Accounting Policies

Invesco Premier Portfolio (the “Fund”) is a series of AIM Treasurer’s Series Trust (Invesco Treasurer’s Series Trust) (the “Trust”). The Trust is a Delaware statutory trust registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as an open-end series management investment company consisting of two separate portfolios and authorized to issue an unlimited number of shares of beneficial interest. The assets, liabilities and operations of the portfolio are accounted for separately. Information presented in these financial statements pertains only to the Fund. Matters affecting the portfolio or class will be voted on exclusively by the shareholders of such portfolio or class.

The Fund’s investment objective is to provide current income consistent with preservation of capital and liquidity.

The Fund currently consists of six classes of shares: Investor Class, Institutional Class, Private Investment Class, Personal Investment Class, Reserve Class and Resource Class. Investor Class shares of the Fund are available only to certain investors. Each class of shares is sold at net asset value.

The Fund is an investment company and accordingly follows the investment company accounting and reporting guidance in accordance with Financial Accounting Standards Board Accounting Standards Codification Topic 946, Financial Services – Investment Companies.

The Fund is a “retail money market fund” as defined in Rule 2a-7 under the 1940 Act, and seeks to maintain a stable or constant NAV of $1.00 per share using an amortized cost method of valuation. “Retail money market funds” are required to adopt policies and procedures reasonably designed to limit investments in the Fund to accounts beneficially owned by natural persons.

The Fund may impose a fee upon the sale of shares or may temporarily suspend the ability to sell shares if the Fund’s liquidity falls below required minimums or because of market conditions or other factors.

The following is a summary of the significant accounting policies followed by the Fund in the preparation of their financial statements.

A. Security Valuations – The Fund’s securities are recorded on the basis of amortized cost which approximates value as permitted by Rule 2a-7 under the 1940 Act. This method values a security at its cost on the date of purchase and, thereafter, assumes a constant amortization to maturity of any premiums or accretion of any discounts.

Because of the inherent uncertainties of valuation, the values reflected in the financial statements may materially differ from the value received upon actual sale of those investments.

The Fund may invest in securities that are subject to interest rate risk, meaning the risk that the prices will generally fall as interest rates rise and, conversely, the prices will generally rise as interest rates fall. Specific securities differ in their sensitivity to changes in interest rates depending on their individual characteristics. Changes in interest rates may result in increased market volatility, which may affect the value and/or liquidity of certain Fund investments.

B. Securities Transactions and Investment Income – Securities transactions are accounted for on a trade date basis. Realized gains or losses on sales are computed on the basis of specific identification of the securities sold. Interest income (net of withholding tax, if any) is recorded on the accrual basis from settlement date and includes coupon interest and amortization of premium and accretion of discount on debt securities as applicable.

The Fund may periodically participate in litigation related to the Fund’s investments. As such, the Fund may receive proceeds from litigation settlements involving each Fund’s investments. Any proceeds received are included in the Statements of Operations as realized gain (loss) for investments no longer held and as unrealized gain (loss) for investments still held.

Brokerage commissions and mark ups are considered transaction costs and are recorded as an increase to the cost basis of securities purchased and/or a reduction of proceeds on a sale of securities. Such transaction costs are included in the determination of net realized gain (loss) from investment securities reported in the Statement of Operations and the Statement of Changes in Net Assets and the net realized gains (losses) on securities per share in the Financial Highlights. Transaction costs are included in the calculation of the Fund’s net asset value and, accordingly, they reduce the Fund’s total returns. These transaction costs are not considered operating expenses and are not reflected in net investment income reported in the Statement of Operations and the Statement of Changes in Net Assets, or the net investment income per share and the ratios of expenses and net investment income reported in the Financial Highlights, nor are they limited by any expense limitation arrangements between the Fund and the investment adviser.

The Fund allocates realized capital gains and losses to a class based on the relative net assets of the class. The Fund allocates income to a class based on the relative value of the settled shares of the class.

C. Country Determination – For the purposes of making investment selection decisions and presentation in the Schedule of Investments, the investment adviser may determine the country in which an issuer is located and/or credit risk exposure based on various factors. These factors include the laws of the country under which the issuer is organized, where the issuer maintains a principal office, the country in which the issuer derives 50% or more of its total revenues and the country that has the primary market for the issuer’s securities, as well as other criteria. Among the other criteria that may be evaluated for making this determination are the country in which the issuer maintains 50% or more of its assets, the type of security, financial guarantees and enhancements, the nature of the collateral and the sponsor organization. Country of issuer and/or credit risk exposure has been determined to be the United States of America, unless otherwise noted.

D. Distributions – It is the policy of the Fund to declare dividends from net investment income daily and pay dividends on the first business day of the following month. The Fund generally distributes net realized capital gain (including net short-term capital gain), if any, annually.

E. Federal Income Taxes – The Fund intends to comply with the requirements of Subchapter M of the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), necessary to qualify as a regulated investment company and to distribute substantially all of the Fund’s taxable earnings to shareholders. As such, the Fund will not be subject to federal income taxes on otherwise taxable income (including net realized capital gain) that is distributed to shareholders. Therefore, no provision for federal income taxes is recorded in the financial statements.

The Fund recognizes the tax benefits of uncertain tax positions only when the position is more likely than not to be sustained. Management has analyzed the Fund’s uncertain tax positions and concluded that no liability for unrecognized tax benefits should be recorded related to uncertain tax positions. Management is not aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will change materially in the next 12 months.

11 AIM Treasurer’s Series Trust (Invesco Treasurer’s Series Trust)

The Fund files tax returns in the U.S. Federal jurisdiction and certain other jurisdictions. Generally, the Fund is subject to examinations by such taxing authorities for up to three years after the filing of the return for the tax period.

F. Expenses – Fees provided for under the Rule 12b-1 plan of a particular class of the Fund and which are directly attributable to that class are charged to the operations of such class. All other expenses are allocated among the classes based on relative net assets.

G. Accounting Estimates – The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period including estimates and assumptions related to taxation. Actual results could differ from those estimates by a significant amount. In addition, the Fund monitors for material events or transactions that may occur or become known after the period-end date and before the date the financial statements are released to print.

H. Indemnifications – Under the Trust’s organizational documents, each Trustee, officer, employee or other agent of the Trust is indemnified against certain liabilities that may arise out of the performance of their duties to the Fund. Additionally, in the normal course of business, the Fund enters into contracts, including the Fund’s servicing agreements, that contain a variety of indemnification clauses. The Fund’s maximum exposure under these arrangements is unknown as this would involve future claims that may be made against such Fund that have not yet occurred. The risk of material loss as a result of such indemnification claims is considered remote.

I. Repurchase Agreements – The Fund may enter into repurchase agreements. Collateral on repurchase agreements, including the Fund’s pro-rata interest in joint repurchase agreements, is taken into possession by the Fund upon entering into the repurchase agreement. Collateral consisting of U.S. Government Securities and U.S. Government Sponsored Agency Securities is marked to market daily to ensure its market value is at least 102% of the sales price of the repurchase agreement. Collateral consisting of non-government securities is marked to market daily to ensure its market value is at least 105% of the sales price of the repurchase agreement. The investments in some repurchase agreements, pursuant to procedures approved by the Board of Trustees, are through participation with other mutual funds, private accounts and certain non-registered investment companies managed by the investment advisor or its affiliates (“Joint repurchase agreements”). The principal amount of the repurchase agreement is equal to the value at period-end. If the seller of a repurchase agreement fails to repurchase the security in accordance with the terms of the agreement, the Fund might incur expenses in enforcing its rights, and could experience losses, including a decline in the value of the collateral and loss of income.

J. Other Risks – The effect on performance from investing in securities issued or guaranteed by companies in the banking and financial services industries will depend to a greater extent on the overall condition of those industries. Financial services companies are highly dependent on the supply of short-term financing. The value of securities of issuers in the banking and financial services industry can be sensitive to changes in government regulation and interest rates and to economic downturns in the United States and abroad.

U.S. dollar-denominated securities carrying foreign credit exposure may be affected by unfavorable political, economic or governmental developments that could affect payments of principal and interest.

K. COVID-19 Risk – The COVID-19 strain of coronavirus has resulted in instances of market closures and dislocations, extreme volatility, liquidity constraints and increased trading costs. Efforts to contain its spread have resulted in travel restrictions, disruptions of healthcare systems, business operations (including business closures) and supply chains, layoffs, lower consumer demand and employee availability, and defaults and credit downgrades, among other significant economic impacts that have disrupted global economic activity across many industries. Such economic impacts may exacerbate other pre-existing political, social and economic risks locally or globally and cause general concern and uncertainty.

The full economic impact and ongoing effects of COVID-19 (or other future epidemics or pandemics) at the macro-level and on individual businesses are unpredictable and may result in significant and prolonged effects on the Fund’s performance.

NOTE 2–Advisory Fees and Other Fees Paid to Affiliates

The Trust has entered into a master investment advisory agreement with Invesco Advisers, Inc. (the “Adviser” or “Invesco”). Under the terms of the investment advisory agreement, the Fund accrues daily and pays monthly an advisory fee to the Adviser at an annual rate of 0.25% of the Fund’s average daily net assets. Pursuant to the master investment advisory agreement, the Adviser bears all expenses incurred by the Fund in connection with its operations, except for (1) interest, taxes and extraordinary items such as litigation costs; (2) brokers’ commissions, issue and transfer taxes, and other costs chargeable to the Fund in connection with securities transactions to which the Fund is a party or in connection with securities owned by the Fund; and (3) other expenditures which are capitalized in accordance with generally accepted accounting principles applicable to investment companies.

Under the terms of a master sub-advisory agreement between the Adviser to the Fund and each of Invesco Asset Management Deutschland GmbH, Invesco Asset Management Limited, Invesco Asset Management (Japan) Limited, Invesco Hong Kong Limited, Inc., Invesco Senior Secured Management, Inc. and Invesco Canada Ltd. and separate sub-advisory agreements with Invesco Capital Management LLC and Invesco Asset Management (India) Private Limited (collectively, the “Affiliated Sub-Advisers”) the Adviser, not the Fund, will pay 40% of the fees paid to the Adviser to any such Affiliated Sub-Adviser(s) that provide(s) discretionary investment management services to the Fund based on the percentage of assets allocated to such Sub-Adviser(s).

The Adviser has contractually agreed, through at least December 31, 2022, to waive advisory fees equal to 0.07% of the average daily net assets of the Fund.

For the six months ended February 28, 2022, the Adviser waived advisory fees and/or reimbursed Fund expenses in the following amounts:

Invesco Premier Portfolio $ 394,901

12 AIM Treasurer’s Series Trust (Invesco Treasurer’s Series Trust)

Further, Invesco and/or Invesco Distributors, Inc. (“IDI”) voluntarily waived fees and/or reimbursed expenses in order to increase the yields of the Fund. Voluntary fee waivers and/or reimbursements may be modified or discontinued at any time upon consultation with the Board of Trustees without further    notice to investors. Voluntary fee waivers for the six months ended February 28, 2022 are shown below:

		Private	Personal
		Investment	Investment	Reserve	Resource
	Fund Level	Class	Class	Class	Class
Invesco Premier Portfolio	$45,340	$187	$22,229	$45	$2,447

The Trust has entered into a master administrative services agreement with Invesco to provide accounting services to the Fund. The Trust has also entered into a transfer agency and service agreement with Invesco Investment Services, Inc. (“IIS”) to provide transfer agency and shareholder services to the Fund. Invesco and IIS do not charge the Fund any fees under these agreements. Also, Invesco has entered into a sub-administration agreement whereby The Bank of New York Mellon (“BNY Mellon”) serves as fund accountant and provides certain administrative services to the Fund. Pursuant to a custody agreement with the Trust on behalf of the Fund, BNY Mellon also serves as the Fund’s custodian.

The Trust has entered into master distribution agreements with IDI to serve as the distributor for the Investor Class, Institutional Class, Personal Investment Class, Private Investment Class, Reserve Class and Resource Class shares. The Trust has adopted plans pursuant to Rule 12b-1 under the 1940 Act with respect to the Fund’s Personal Investment Class, Private Investment Class, Reserve Class and Resource Class shares (collectively, the “Plans”). The Fund, pursuant to the Plans, pays IDI compensation at the annual rate of 0.55% of the Fund’s average daily net assets of Personal Investment Class shares, 0.30% of the average daily net assets of Private Investment Class shares, 0.87% of the average daily net assets of Reserve Class shares and 0.16% of the average daily net assets of Resource Class shares. The fees are accrued daily and paid monthly. Of the Plan payments, up to 0.25% of the average daily net assets of each class of shares may be paid to furnish continuing personal shareholder services to customers who purchase and own shares of such class. Any amounts not paid as a service fee under the Plans would constitute an asset-based sales charge. Rules of the Financial Industry Regulatory Authority (“FINRA”) impose a cap on the total sales charges, including asset-based sales charges, that may be paid by any class of shares of the Fund. For the six months ended February 28, 2022, expenses incurred under the plans are shown in the Statement of Operations as Distribution fees.

Certain officers and trustees of the Trust are officers and directors of the Adviser, IIS and/or IDI.

NOTE 3–Additional Valuation Information

GAAP defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date, under current market conditions. GAAP establishes a hierarchy that prioritizes the inputs to valuation methods, giving the highest priority to readily available unadjusted quoted prices in an active market for identical assets (Level 1) and the lowest priority to significant unobservable inputs (Level 3), generally when market prices are not readily available or are unreliable. Based on the valuation inputs, the securities or other investments are tiered into one of three levels. Changes in valuation methods may result in transfers in or out of an investment’s assigned level:

Level 1 –	Prices are determined using quoted prices in an active market for identical assets.
Level 2 –	Prices are determined using other significant observable inputs. Observable inputs are inputs that other market participants may use in pricing a security. These may include quoted prices for similar securities, interest rates, prepayment speeds, credit risk, yield curves, loss severities, default rates, discount rates, volatilities and others.
Level 3 –	Prices are determined using significant unobservable inputs. In situations where quoted prices or observable inputs are unavailable (for example, when there is little or no market activity for an investment at the end of the period), unobservable inputs may be used. Unobservable inputs reflect the Fund’s own assumptions about the factors market participants would use in determining fair value of the securities or instruments and would be based on the best available information.

As of February 28, 2022, all of the securities in the Fund were valued based on Level 2 inputs (see the Schedule of Investments for security categories). The level assigned to the securities valuations may not be an indication of the risk or liquidity associated with investing in those securities. Because of the inherent uncertainties of valuation, the values reflected in the financial statements may materially differ from the value received upon actual sale of those investments.

NOTE 4–Security Transactions with Affiliated Funds

The Fund is permitted to purchase or sell securities from or to certain other Invesco Funds under specified conditions outlined in procedures adopted by the Board of Trustees of the Trust. The procedures have been designed to ensure that any purchase or sale of securities by the Fund from or to another fund or portfolio that is or could be considered an affiliate by virtue of having a common investment adviser (or affiliated investment advisers), common Trustees and/or common officers complies with Rule 17a-7 of the 1940 Act. Further, as defined under the procedures, each transaction is effected at the current market price. Pursuant to these procedures, for the six months ended February 28, 2022, the Fund engaged in securities purchases of $115,591,084 and securities sales of $84,848,987, which did not result in any net realized gains (losses).

NOTE 5–Trustees’ and Officers’ Fees and Benefits

Remuneration is paid to certain Trustees and Officers of the Trust. Trustees have the option to defer their compensation. Those Trustees who defer compensation have the option to select various Invesco Funds in which their deferral accounts shall be deemed to be invested.

Certain current Trustees were eligible to participate in a retirement plan that provided for benefits to be paid upon retirement to Trustees over a period of time based on the number of years of service. The Fund may have certain former Trustees that also participate in a retirement plan and receive benefits under such plan. The Fund’s allocable portion of the remuneration paid to the Trustees, including its allocable portion of the fees and benefits of the deferred compensation plan and retirement plan are paid by Invesco and not by the Trust.

13 AIM Treasurer’s Series Trust (Invesco Treasurer’s Series Trust)

NOTE 6–Cash Balances

The Fund is permitted to temporarily overdraft or leave balances in its account with BNY Mellon, the custodian bank. Such balances, if any at period-end, are shown in the Statement of Assets and Liabilities under the payable caption Amount due custodian. To compensate BNY Mellon or the Fund for such activity, the Fund may either (1) pay to or receive from BNY Mellon compensation at a rate agreed upon by BNY Mellon and Invesco, not to exceed the contractually agreed upon rate; or (2) leave funds or overdraft funds as a compensating balance in the account so BNY Mellon or the Fund can be compensated for use of funds.

NOTE 7–Tax Information

The amount and character of income and gains to be distributed are determined in accordance with income tax regulations, which may differ from GAAP. Reclassifications are made to the Fund’s capital accounts to reflect income and gains available for distribution (or available capital loss carryforward) under income tax regulations. The tax character of distributions paid during the year and the tax components of net assets will be reported at the Fund’s fiscal year-end.

Capital loss carryforward is calculated and reported as of a specific date. Results of transactions and other activity after that date may affect the amount of capital loss carryforward actually available for the Fund to utilize. The ability to utilize capital loss carryforwards in the future may be limited under the Internal Revenue Code and related regulations based on the results of future transactions.

The Fund did not have any capital loss carryforward as of August 31, 2021.

^(a)  There are entities that are record owners of more than 5% of the outstanding shares of the Fund and in the aggregate own 71% of the outstanding shares of the Fund. IDI has an agreement with these entities to sell Fund shares. The Fund, Invesco and/or Invesco affiliates may make payments to these entities, which are considered to be related to the Fund, for providing services to the Fund, Invesco and/or Invesco affiliates including but not limited to services such as securities brokerage, distribution, third party record keeping and account servicing.

Calculating your ongoing Fund expenses

Example

As a shareholder in the Resource Class, you incur ongoing costs, including management fees, distribution and/or service (12b-1) fees and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period September 1, 2021 through February 28, 2022.

Actual expenses

The table below provides information about actual account values and actual expenses. You may use the information in this table, together with the amount you invested, to estimate the expenses that you paid over the period. 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 in the table under the heading entitled “Actual Expenses Paid During Period” to estimate the expenses you paid on your account during this period.

Hypothetical example for comparison purposes

The table below also provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return.

    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 the 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 transaction costs, such as sales charges (loads) on purchase payments or contingent deferred sales charges on redemptions, if any. Therefore, the hypothetical information 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 transaction costs were included, your costs would have been higher.

		ACTUAL		HYPOTHETICAL (5% annual return before expenses)
Resource Class	Beginning Account Value (09/01/21)	Ending Account Value (02/28/22)1	Expenses Paid During Period2	Ending Account Value (02/28/22)	Expenses Paid During Period2	Annualized Expense Ratio
Invesco Premier Portfolio	$1,000.00	$1,000.10	$0.84	$1,023.95	$0.85	0.17%

¹  The actual ending account value is based on the actual total return of the Fund for the period September 1, 2021 through February 28, 2022, after actual expenses and will differ from the hypothetical ending account value which is based on the Fund’s expense ratio and a hypothetical annual return of 5% before expenses.

²  Expenses are equal to the Fund’s annualized expense ratio as indicated above multiplied by the average account value over the period, multiplied by 181/365 to reflect the most recent fiscal half year.

Weighted average maturity (WAM) is an average of the maturities of all securities held in the portfolio, weighted by each security’s percentage of net assets. The days to maturity for WAM is the lower of the stated maturity date or next interest rate reset date. WAM reflects how a portfolio would react to interest rate changes.
Weighted average life (WAL) is an average of all the maturities of all securities held in the portfolio, weighted by each security’s percentage of net assets. The days to maturity for WAL is the lower of the stated maturity date or next demand feature date. WAL reflects how a portfolio would react to deteriorating credit (widening spreads) or tightening liquidity conditions.

Notes to Financial Statements

February 28, 2022

(Unaudited)

NOTE 1–Significant Accounting Policies

Invesco Premier Portfolio (the “Fund”) is a series of AIM Treasurer’s Series Trust (Invesco Treasurer’s Series Trust) (the “Trust”). The Trust is a Delaware statutory trust registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as an open-end series management investment company consisting of two separate portfolios and authorized to issue an unlimited number of shares of beneficial interest. The assets, liabilities and operations of the portfolio are accounted for separately. Information presented in these financial statements pertains only to the Fund. Matters affecting the portfolio or class will be voted on exclusively by the shareholders of such portfolio or class.

The Fund’s investment objective is to provide current income consistent with preservation of capital and liquidity.

The Fund currently consists of six classes of shares: Investor Class, Institutional Class, Private Investment Class, Personal Investment Class, Reserve Class and Resource Class. Investor Class shares of the Fund are available only to certain investors. Each class of shares is sold at net asset value.

The Fund is an investment company and accordingly follows the investment company accounting and reporting guidance in accordance with Financial Accounting Standards Board Accounting Standards Codification Topic 946, Financial Services – Investment Companies.

The Fund is a “retail money market fund” as defined in Rule 2a-7 under the 1940 Act, and seeks to maintain a stable or constant NAV of $1.00 per share using an amortized cost method of valuation. “Retail money market funds” are required to adopt policies and procedures reasonably designed to limit investments in the Fund to accounts beneficially owned by natural persons.

The Fund may impose a fee upon the sale of shares or may temporarily suspend the ability to sell shares if the Fund’s liquidity falls below required minimums or because of market conditions or other factors.

The following is a summary of the significant accounting policies followed by the Fund in the preparation of their financial statements.

A. Security Valuations – The Fund’s securities are recorded on the basis of amortized cost which approximates value as permitted by Rule 2a-7 under the 1940 Act. This method values a security at its cost on the date of purchase and, thereafter, assumes a constant amortization to maturity of any premiums or accretion of any discounts.

Because of the inherent uncertainties of valuation, the values reflected in the financial statements may materially differ from the value received upon actual sale of those investments.

The Fund may invest in securities that are subject to interest rate risk, meaning the risk that the prices will generally fall as interest rates rise and, conversely, the prices will generally rise as interest rates fall. Specific securities differ in their sensitivity to changes in interest rates depending on their individual characteristics. Changes in interest rates may result in increased market volatility, which may affect the value and/or liquidity of certain Fund investments.

B. Securities Transactions and Investment Income – Securities transactions are accounted for on a trade date basis. Realized gains or losses on sales are computed on the basis of specific identification of the securities sold. Interest income (net of withholding tax, if any) is recorded on the accrual basis from settlement date and includes coupon interest and amortization of premium and accretion of discount on debt securities as applicable.

The Fund may periodically participate in litigation related to the Fund’s investments. As such, the Fund may receive proceeds from litigation settlements involving each Fund’s investments. Any proceeds received are included in the Statements of Operations as realized gain (loss) for investments no longer held and as unrealized gain (loss) for investments still held.

Brokerage commissions and mark ups are considered transaction costs and are recorded as an increase to the cost basis of securities purchased and/or a reduction of proceeds on a sale of securities. Such transaction costs are included in the determination of net realized gain (loss) from investment securities reported in the Statement of Operations and the Statement of Changes in Net Assets and the net realized gains (losses) on securities per share in the Financial Highlights. Transaction costs are included in the calculation of the Fund’s net asset value and, accordingly, they reduce the Fund’s total returns. These transaction costs are not considered operating expenses and are not reflected in net investment income reported in the Statement of Operations and the Statement of Changes in Net Assets, or the net investment income per share and the ratios of expenses and net investment income reported in the Financial Highlights, nor are they limited by any expense limitation arrangements between the Fund and the investment adviser.

The Fund allocates realized capital gains and losses to a class based on the relative net assets of the class. The Fund allocates income to a class based on the relative value of the settled shares of the class.

C. Country Determination – For the purposes of making investment selection decisions and presentation in the Schedule of Investments, the investment adviser may determine the country in which an issuer is located and/or credit risk exposure based on various factors. These factors include the laws of the country under which the issuer is organized, where the issuer maintains a principal office, the country in which the issuer derives 50% or more of its total revenues and the country that has the primary market for the issuer’s securities, as well as other criteria. Among the other criteria that may be evaluated for making this determination are the country in which the issuer maintains 50% or more of its assets, the type of security, financial guarantees and enhancements, the nature of the collateral and the sponsor organization. Country of issuer and/or credit risk exposure has been determined to be the United States of America, unless otherwise noted.

D. Distributions – It is the policy of the Fund to declare dividends from net investment income daily and pay dividends on the first business day of the following month. The Fund generally distributes net realized capital gain (including net short-term capital gain), if any, annually.

E. Federal Income Taxes – The Fund intends to comply with the requirements of Subchapter M of the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), necessary to qualify as a regulated investment company and to distribute substantially all of the Fund’s taxable earnings to shareholders. As such, the Fund will not be subject to federal income taxes on otherwise taxable income (including net realized capital gain) that is distributed to shareholders. Therefore, no provision for federal income taxes is recorded in the financial statements.

The Fund recognizes the tax benefits of uncertain tax positions only when the position is more likely than not to be sustained. Management has analyzed the Fund’s uncertain tax positions and concluded that no liability for unrecognized tax benefits should be recorded related to uncertain tax positions. Management is not aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will change materially in the next 12 months.

11 AIM Treasurer’s Series Trust (Invesco Treasurer’s Series Trust)

The Fund files tax returns in the U.S. Federal jurisdiction and certain other jurisdictions. Generally, the Fund is subject to examinations by such taxing authorities for up to three years after the filing of the return for the tax period.

F. Expenses – Fees provided for under the Rule 12b-1 plan of a particular class of the Fund and which are directly attributable to that class are charged to the operations of such class. All other expenses are allocated among the classes based on relative net assets.

G. Accounting Estimates – The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period including estimates and assumptions related to taxation. Actual results could differ from those estimates by a significant amount. In addition, the Fund monitors for material events or transactions that may occur or become known after the period-end date and before the date the financial statements are released to print.

H. Indemnifications – Under the Trust’s organizational documents, each Trustee, officer, employee or other agent of the Trust is indemnified against certain liabilities that may arise out of the performance of their duties to the Fund. Additionally, in the normal course of business, the Fund enters into contracts, including the Fund’s servicing agreements, that contain a variety of indemnification clauses. The Fund’s maximum exposure under these arrangements is unknown as this would involve future claims that may be made against such Fund that have not yet occurred. The risk of material loss as a result of such indemnification claims is considered remote.

I. Repurchase Agreements – The Fund may enter into repurchase agreements. Collateral on repurchase agreements, including the Fund’s pro-rata interest in joint repurchase agreements, is taken into possession by the Fund upon entering into the repurchase agreement. Collateral consisting of U.S. Government Securities and U.S. Government Sponsored Agency Securities is marked to market daily to ensure its market value is at least 102% of the sales price of the repurchase agreement. Collateral consisting of non-government securities is marked to market daily to ensure its market value is at least 105% of the sales price of the repurchase agreement. The investments in some repurchase agreements, pursuant to procedures approved by the Board of Trustees, are through participation with other mutual funds, private accounts and certain non-registered investment companies managed by the investment advisor or its affiliates (“Joint repurchase agreements”). The principal amount of the repurchase agreement is equal to the value at period-end. If the seller of a repurchase agreement fails to repurchase the security in accordance with the terms of the agreement, the Fund might incur expenses in enforcing its rights, and could experience losses, including a decline in the value of the collateral and loss of income.

J. Other Risks – The effect on performance from investing in securities issued or guaranteed by companies in the banking and financial services industries will depend to a greater extent on the overall condition of those industries. Financial services companies are highly dependent on the supply of short-term financing. The value of securities of issuers in the banking and financial services industry can be sensitive to changes in government regulation and interest rates and to economic downturns in the United States and abroad.

U.S. dollar-denominated securities carrying foreign credit exposure may be affected by unfavorable political, economic or governmental developments that could affect payments of principal and interest.

K. COVID-19 Risk – The COVID-19 strain of coronavirus has resulted in instances of market closures and dislocations, extreme volatility, liquidity constraints and increased trading costs. Efforts to contain its spread have resulted in travel restrictions, disruptions of healthcare systems, business operations (including business closures) and supply chains, layoffs, lower consumer demand and employee availability, and defaults and credit downgrades, among other significant economic impacts that have disrupted global economic activity across many industries. Such economic impacts may exacerbate other pre-existing political, social and economic risks locally or globally and cause general concern and uncertainty.

The full economic impact and ongoing effects of COVID-19 (or other future epidemics or pandemics) at the macro-level and on individual businesses are unpredictable and may result in significant and prolonged effects on the Fund’s performance.

NOTE 2–Advisory Fees and Other Fees Paid to Affiliates

The Trust has entered into a master investment advisory agreement with Invesco Advisers, Inc. (the “Adviser” or “Invesco”). Under the terms of the investment advisory agreement, the Fund accrues daily and pays monthly an advisory fee to the Adviser at an annual rate of 0.25% of the Fund’s average daily net assets. Pursuant to the master investment advisory agreement, the Adviser bears all expenses incurred by the Fund in connection with its operations, except for (1) interest, taxes and extraordinary items such as litigation costs; (2) brokers’ commissions, issue and transfer taxes, and other costs chargeable to the Fund in connection with securities transactions to which the Fund is a party or in connection with securities owned by the Fund; and (3) other expenditures which are capitalized in accordance with generally accepted accounting principles applicable to investment companies.

Under the terms of a master sub-advisory agreement between the Adviser to the Fund and each of Invesco Asset Management Deutschland GmbH, Invesco Asset Management Limited, Invesco Asset Management (Japan) Limited, Invesco Hong Kong Limited, Inc., Invesco Senior Secured Management, Inc. and Invesco Canada Ltd. and separate sub-advisory agreements with Invesco Capital Management LLC and Invesco Asset Management (India) Private Limited (collectively, the “Affiliated Sub-Advisers”) the Adviser, not the Fund, will pay 40% of the fees paid to the Adviser to any such Affiliated Sub-Adviser(s) that provide(s) discretionary investment management services to the Fund based on the percentage of assets allocated to such Sub-Adviser(s).

The Adviser has contractually agreed, through at least December 31, 2022, to waive advisory fees equal to 0.07% of the average daily net assets of the Fund.

For the six months ended February 28, 2022, the Adviser waived advisory fees and/or reimbursed Fund expenses in the following amounts:

Invesco Premier Portfolio $ 394,901

12 AIM Treasurer’s Series Trust (Invesco Treasurer’s Series Trust)

Further, Invesco and/or Invesco Distributors, Inc. (“IDI”) voluntarily waived fees and/or reimbursed expenses in order to increase the yields of the Fund. Voluntary fee waivers and/or reimbursements may be modified or discontinued at any time upon consultation with the Board of Trustees without further    notice to investors. Voluntary fee waivers for the six months ended February 28, 2022 are shown below:

		Private	Personal
		Investment	Investment	Reserve	Resource
	Fund Level	Class	Class	Class	Class
Invesco Premier Portfolio	$45,340	$187	$22,229	$45	$2,447

The Trust has entered into a master administrative services agreement with Invesco to provide accounting services to the Fund. The Trust has also entered into a transfer agency and service agreement with Invesco Investment Services, Inc. (“IIS”) to provide transfer agency and shareholder services to the Fund. Invesco and IIS do not charge the Fund any fees under these agreements. Also, Invesco has entered into a sub-administration agreement whereby The Bank of New York Mellon (“BNY Mellon”) serves as fund accountant and provides certain administrative services to the Fund. Pursuant to a custody agreement with the Trust on behalf of the Fund, BNY Mellon also serves as the Fund’s custodian.

The Trust has entered into master distribution agreements with IDI to serve as the distributor for the Investor Class, Institutional Class, Personal Investment Class, Private Investment Class, Reserve Class and Resource Class shares. The Trust has adopted plans pursuant to Rule 12b-1 under the 1940 Act with respect to the Fund’s Personal Investment Class, Private Investment Class, Reserve Class and Resource Class shares (collectively, the “Plans”). The Fund, pursuant to the Plans, pays IDI compensation at the annual rate of 0.55% of the Fund’s average daily net assets of Personal Investment Class shares, 0.30% of the average daily net assets of Private Investment Class shares, 0.87% of the average daily net assets of Reserve Class shares and 0.16% of the average daily net assets of Resource Class shares. The fees are accrued daily and paid monthly. Of the Plan payments, up to 0.25% of the average daily net assets of each class of shares may be paid to furnish continuing personal shareholder services to customers who purchase and own shares of such class. Any amounts not paid as a service fee under the Plans would constitute an asset-based sales charge. Rules of the Financial Industry Regulatory Authority (“FINRA”) impose a cap on the total sales charges, including asset-based sales charges, that may be paid by any class of shares of the Fund. For the six months ended February 28, 2022, expenses incurred under the plans are shown in the Statement of Operations as Distribution fees.

Certain officers and trustees of the Trust are officers and directors of the Adviser, IIS and/or IDI.

NOTE 3–Additional Valuation Information

GAAP defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date, under current market conditions. GAAP establishes a hierarchy that prioritizes the inputs to valuation methods, giving the highest priority to readily available unadjusted quoted prices in an active market for identical assets (Level 1) and the lowest priority to significant unobservable inputs (Level 3), generally when market prices are not readily available or are unreliable. Based on the valuation inputs, the securities or other investments are tiered into one of three levels. Changes in valuation methods may result in transfers in or out of an investment’s assigned level:

Level 1 –	Prices are determined using quoted prices in an active market for identical assets.
Level 2 –	Prices are determined using other significant observable inputs. Observable inputs are inputs that other market participants may use in pricing a security. These may include quoted prices for similar securities, interest rates, prepayment speeds, credit risk, yield curves, loss severities, default rates, discount rates, volatilities and others.
Level 3 –	Prices are determined using significant unobservable inputs. In situations where quoted prices or observable inputs are unavailable (for example, when there is little or no market activity for an investment at the end of the period), unobservable inputs may be used. Unobservable inputs reflect the Fund’s own assumptions about the factors market participants would use in determining fair value of the securities or instruments and would be based on the best available information.

As of February 28, 2022, all of the securities in the Fund were valued based on Level 2 inputs (see the Schedule of Investments for security categories). The level assigned to the securities valuations may not be an indication of the risk or liquidity associated with investing in those securities. Because of the inherent uncertainties of valuation, the values reflected in the financial statements may materially differ from the value received upon actual sale of those investments.

NOTE 4–Security Transactions with Affiliated Funds

The Fund is permitted to purchase or sell securities from or to certain other Invesco Funds under specified conditions outlined in procedures adopted by the Board of Trustees of the Trust. The procedures have been designed to ensure that any purchase or sale of securities by the Fund from or to another fund or portfolio that is or could be considered an affiliate by virtue of having a common investment adviser (or affiliated investment advisers), common Trustees and/or common officers complies with Rule 17a-7 of the 1940 Act. Further, as defined under the procedures, each transaction is effected at the current market price. Pursuant to these procedures, for the six months ended February 28, 2022, the Fund engaged in securities purchases of $115,591,084 and securities sales of $84,848,987, which did not result in any net realized gains (losses).

NOTE 5–Trustees’ and Officers’ Fees and Benefits

Remuneration is paid to certain Trustees and Officers of the Trust. Trustees have the option to defer their compensation. Those Trustees who defer compensation have the option to select various Invesco Funds in which their deferral accounts shall be deemed to be invested.

Certain current Trustees were eligible to participate in a retirement plan that provided for benefits to be paid upon retirement to Trustees over a period of time based on the number of years of service. The Fund may have certain former Trustees that also participate in a retirement plan and receive benefits under such plan. The Fund’s allocable portion of the remuneration paid to the Trustees, including its allocable portion of the fees and benefits of the deferred compensation plan and retirement plan are paid by Invesco and not by the Trust.

13 AIM Treasurer’s Series Trust (Invesco Treasurer’s Series Trust)

NOTE 6–Cash Balances

The Fund is permitted to temporarily overdraft or leave balances in its account with BNY Mellon, the custodian bank. Such balances, if any at period-end, are shown in the Statement of Assets and Liabilities under the payable caption Amount due custodian. To compensate BNY Mellon or the Fund for such activity, the Fund may either (1) pay to or receive from BNY Mellon compensation at a rate agreed upon by BNY Mellon and Invesco, not to exceed the contractually agreed upon rate; or (2) leave funds or overdraft funds as a compensating balance in the account so BNY Mellon or the Fund can be compensated for use of funds.

NOTE 7–Tax Information

The amount and character of income and gains to be distributed are determined in accordance with income tax regulations, which may differ from GAAP. Reclassifications are made to the Fund’s capital accounts to reflect income and gains available for distribution (or available capital loss carryforward) under income tax regulations. The tax character of distributions paid during the year and the tax components of net assets will be reported at the Fund’s fiscal year-end.

Capital loss carryforward is calculated and reported as of a specific date. Results of transactions and other activity after that date may affect the amount of capital loss carryforward actually available for the Fund to utilize. The ability to utilize capital loss carryforwards in the future may be limited under the Internal Revenue Code and related regulations based on the results of future transactions.

The Fund did not have any capital loss carryforward as of August 31, 2021.

Calculating your ongoing Fund expenses

Example

As a shareholder in the Private Investment Class, you incur ongoing costs, including management fees, distribution and/or service (12b-1) fees and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period September 1, 2021 through February 28, 2022.

Actual expenses

The table below provides information about actual account values and actual expenses. You may use the information in this table, together with the amount you invested, to estimate the expenses that you paid over the period. 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 in the table under the heading entitled “Actual Expenses Paid During Period” to estimate the expenses you paid on your account during this period.

Hypothetical example for comparison purposes

The table below also provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return.

    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 the 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 transaction costs, such as sales charges (loads) on purchase payments or contingent deferred sales charges on redemptions, if any. Therefore, the hypothetical information 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 transaction costs were included, your costs would have been higher.

		ACTUAL		HYPOTHETICAL (5% annual return before expenses)
Private Investment   Class	Beginning Account Value (09/01/21)	Ending Account Value (02/28/22)1	Expenses Paid During Period2	Ending Account Value (02/28/22)	Expenses Paid During Period2	Annualized   Expense   Ratio
Invesco Premier Portfolio	$1,000.00	$1,000.10	$0.84	$1,023.95	$0.85	0.17%

¹  The actual ending account value is based on the actual total return of the Fund for the period September 1, 2021 through February 28, 2022, after actual expenses and will differ from the hypothetical ending account value which is based on the Fund’s expense ratio and a hypothetical annual return of 5% before expenses.

²  Expenses are equal to the Fund’s annualized expense ratio as indicated above multiplied by the average account value over the period, multiplied by 181/365 to reflect the most recent fiscal half year.

Weighted average life (WAL) is an average of all the maturities of all securities held in the portfolio, weighted by each security’s percentage of net assets. The days to maturity for WAL is the lower of the stated maturity date or next demand feature date. WAL reflects how a portfolio would react to deteriorating credit (widening spreads) or tightening liquidity conditions.

Notes to Financial Statements

February 28, 2022

(Unaudited)

NOTE 1–Significant Accounting Policies

Invesco Premier Portfolio (the “Fund”) is a series of AIM Treasurer’s Series Trust (Invesco Treasurer’s Series Trust) (the “Trust”). The Trust is a Delaware statutory trust registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as an open-end series management investment company consisting of two separate portfolios and authorized to issue an unlimited number of shares of beneficial interest. The assets, liabilities and operations of the portfolio are accounted for separately. Information presented in these financial statements pertains only to the Fund. Matters affecting the portfolio or class will be voted on exclusively by the shareholders of such portfolio or class.

The Fund’s investment objective is to provide current income consistent with preservation of capital and liquidity.

The Fund currently consists of six classes of shares: Investor Class, Institutional Class, Private Investment Class, Personal Investment Class, Reserve Class and Resource Class. Investor Class shares of the Fund are available only to certain investors. Each class of shares is sold at net asset value.

The Fund is an investment company and accordingly follows the investment company accounting and reporting guidance in accordance with Financial Accounting Standards Board Accounting Standards Codification Topic 946, Financial Services – Investment Companies.

The Fund is a “retail money market fund” as defined in Rule 2a-7 under the 1940 Act, and seeks to maintain a stable or constant NAV of $1.00 per share using an amortized cost method of valuation. “Retail money market funds” are required to adopt policies and procedures reasonably designed to limit investments in the Fund to accounts beneficially owned by natural persons.

The Fund may impose a fee upon the sale of shares or may temporarily suspend the ability to sell shares if the Fund’s liquidity falls below required minimums or because of market conditions or other factors.

The following is a summary of the significant accounting policies followed by the Fund in the preparation of their financial statements.

A. Security Valuations – The Fund’s securities are recorded on the basis of amortized cost which approximates value as permitted by Rule 2a-7 under the 1940 Act. This method values a security at its cost on the date of purchase and, thereafter, assumes a constant amortization to maturity of any premiums or accretion of any discounts.

Because of the inherent uncertainties of valuation, the values reflected in the financial statements may materially differ from the value received upon actual sale of those investments.

The Fund may invest in securities that are subject to interest rate risk, meaning the risk that the prices will generally fall as interest rates rise and, conversely, the prices will generally rise as interest rates fall. Specific securities differ in their sensitivity to changes in interest rates depending on their individual characteristics. Changes in interest rates may result in increased market volatility, which may affect the value and/or liquidity of certain Fund investments.

B. Securities Transactions and Investment Income — Securities transactions are accounted for on a trade date basis. Realized gains or losses on sales are computed on the basis of specific identification of the securities sold. Interest income (net of withholding tax, if any) is recorded on the accrual basis from settlement date and includes coupon interest and amortization of premium and accretion of discount on debt securities as applicable.

The Fund may periodically participate in litigation related to the Fund’s investments. As such, the Fund may receive proceeds from litigation settlements involving each Fund’s investments. Any proceeds received are included in the Statements of Operations as realized gain (loss) for investments no longer held and as unrealized gain (loss) for investments still held.

Brokerage commissions and mark ups are considered transaction costs and are recorded as an increase to the cost basis of securities purchased and/or a reduction of proceeds on a sale of securities. Such transaction costs are included in the determination of net realized gain (loss) from investment securities reported in the Statement of Operations and the Statement of Changes in Net Assets and the net realized gains (losses) on securities per share in the Financial Highlights. Transaction costs are included in the calculation of the Fund’s net asset value and, accordingly, they reduce the Fund’s total returns. These transaction costs are not considered operating expenses and are not reflected in net investment income reported in the Statement of Operations and the Statement of Changes in Net Assets, or the net investment income per share and the ratios of expenses and net investment income reported in the Financial Highlights, nor are they limited by any expense limitation arrangements between the Fund and the investment adviser.

The Fund allocates realized capital gains and losses to a class based on the relative net assets of the class. The Fund allocates income to a class based on the relative value of the settled shares of the class.

C. Country Determination – For the purposes of making investment selection decisions and presentation in the Schedule of Investments, the investment adviser may determine the country in which an issuer is located and/or credit risk exposure based on various factors. These factors include the laws of the country under which the issuer is organized, where the issuer maintains a principal office, the country in which the issuer derives 50% or more of its total revenues and the country that has the primary market for the issuer’s securities, as well as other criteria. Among the other criteria that may be evaluated for making this determination are the country in which the issuer maintains 50% or more of its assets, the type of security, financial guarantees and enhancements, the nature of the collateral and the sponsor organization. Country of issuer and/or credit risk exposure has been determined to be the United States of America, unless otherwise noted.

D. Distributions – It is the policy of the Fund to declare dividends from net investment income daily and pay dividends on the first business day of the following month. The Fund generally distributes net realized capital gain (including net short-term capital gain), if any, annually.

E. Federal Income Taxes – The Fund intends to comply with the requirements of Subchapter M of the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), necessary to qualify as a regulated investment company and to distribute substantially all of the Fund’s taxable earnings to shareholders. As such, the Fund will not be subject to federal income taxes on otherwise taxable income (including net realized capital gain) that is distributed to shareholders. Therefore, no provision for federal income taxes is recorded in the financial statements.

The Fund recognizes the tax benefits of uncertain tax positions only when the position is more likely than not to be sustained. Management has analyzed the Fund’s uncertain tax positions and concluded that no liability for unrecognized tax benefits should be recorded related to uncertain tax positions. Management is not aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will change materially in the next 12 months.

11 AIM Treasurer’s Series Trust (Invesco Treasurer’s Series Trust)

The Fund files tax returns in the U.S. Federal jurisdiction and certain other jurisdictions. Generally, the Fund is subject to examinations by such taxing authorities for up to three years after the filing of the return for the tax period.

F. Expenses - Fees provided for under the Rule 12b-1 plan of a particular class of the Fund and which are directly attributable to that class are charged to the operations of such class. All other expenses are allocated among the classes based on relative net assets.

G. Accounting Estimates - The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period including estimates and assumptions related to taxation. Actual results could differ from those estimates by a significant amount. In addition, the Fund monitors for material events or transactions that may occur or become known after the period-end date and before the date the financial statements are released to print.

H. Indemnifications - Under the Trust’s organizational documents, each Trustee, officer, employee or other agent of the Trust is indemnified against certain liabilities that may arise out of the performance of their duties to the Fund. Additionally, in the normal course of business, the Fund enters into contracts, including the Fund’s servicing agreements, that contain a variety of indemnification clauses. The Fund’s maximum exposure under these arrangements is unknown as this would involve future claims that may be made against such Fund that have not yet occurred. The risk of material loss as a result of such indemnification claims is considered remote.

I. Repurchase Agreements - The Fund may enter into repurchase agreements. Collateral on repurchase agreements, including the Fund’s pro-rata interest in joint repurchase agreements, is taken into possession by the Fund upon entering into the repurchase agreement. Collateral consisting of U.S. Government Securities and U.S. Government Sponsored Agency Securities is marked to market daily to ensure its market value is at least 102% of the sales price of the repurchase agreement. Collateral consisting of non-government securities is marked to market daily to ensure its market value is at least 105% of the sales price of the repurchase agreement. The investments in some repurchase agreements, pursuant to procedures approved by the Board of Trustees, are through participation with other mutual funds, private accounts and certain non-registered investment companies managed by the investment advisor or its affiliates (“Joint repurchase agreements”). The principal amount of the repurchase agreement is equal to the value at period-end. If the seller of a repurchase agreement fails to repurchase the security in accordance with the terms of the agreement, the Fund might incur expenses in enforcing its rights, and could experience losses, including a decline in the value of the collateral and loss of income.

J. Other Risks - The effect on performance from investing in securities issued or guaranteed by companies in the banking and financial services industries will depend to a greater extent on the overall condition of those industries. Financial services companies are highly dependent on the supply of short-term financing. The value of securities of issuers in the banking and financial services industry can be sensitive to changes in government regulation and interest rates and to economic downturns in the United States and abroad.

U.S. dollar-denominated securities carrying foreign credit exposure may be affected by unfavorable political, economic or governmental developments that could affect payments of principal and interest.

K. COVID-19 Risk - The COVID-19 strain of coronavirus has resulted in instances of market closures and dislocations, extreme volatility, liquidity constraints and increased trading costs. Efforts to contain its spread have resulted in travel restrictions, disruptions of healthcare systems, business operations (including business closures) and supply chains, layoffs, lower consumer demand and employee availability, and defaults and credit downgrades, among other significant economic impacts that have disrupted global economic activity across many industries. Such economic impacts may exacerbate other pre-existing political, social and economic risks locally or globally and cause general concern and uncertainty.

The full economic impact and ongoing effects of COVID-19 (or other future epidemics or pandemics) at the macro-level and on individual businesses are unpredictable and may result in significant and prolonged effects on the Fund’s performance.

NOTE 2–Advisory Fees and Other Fees Paid to Affiliates

The Trust has entered into a master investment advisory agreement with Invesco Advisers, Inc. (the “Adviser” or “Invesco”). Under the terms of the investment advisory agreement, the Fund accrues daily and pays monthly an advisory fee to the Adviser at an annual rate of 0.25% of the Fund’s average daily net assets. Pursuant to the master investment advisory agreement, the Adviser bears all expenses incurred by the Fund in connection with its operations, except for (1) interest, taxes and extraordinary items such as litigation costs; (2) brokers’ commissions, issue and transfer taxes, and other costs chargeable to the Fund in connection with securities transactions to which the Fund is a party or in connection with securities owned by the Fund; and (3) other expenditures which are capitalized in accordance with generally accepted accounting principles applicable to investment companies.

Under the terms of a master sub-advisory agreement between the Adviser to the Fund and each of Invesco Asset Management Deutschland GmbH, Invesco Asset Management Limited, Invesco Asset Management (Japan) Limited, Invesco Hong Kong Limited, Inc., Invesco Senior Secured Management, Inc. and Invesco Canada Ltd. and separate sub-advisory agreements with Invesco Capital Management LLC and Invesco Asset Management (India) Private Limited (collectively, the “Affiliated Sub-Advisers”) the Adviser, not the Fund, will pay 40% of the fees paid to the Adviser to any such Affiliated Sub-Adviser(s) that provide(s) discretionary investment management services to the Fund based on the percentage of assets allocated to such Sub-Adviser(s).

The Adviser has contractually agreed, through at least December 31, 2022, to waive advisory fees equal to 0.07% of the average daily net assets of the Fund.

For the six months ended February 28, 2022, the Adviser waived advisory fees and/or reimbursed Fund expenses in the following amounts:

Invesco Premier Portfolio $ 394,901

12 AIM Treasurer’s Series Trust (Invesco Treasurer’s Series Trust)

Further, Invesco and/or Invesco Distributors, Inc. (“IDI”) voluntarily waived fees and/or reimbursed expenses in order to increase the yields of the Fund. Voluntary fee waivers and/or reimbursements may be modified or discontinued at any time upon consultation with the Board of Trustees without further notice to investors. Voluntary fee waivers for the six months ended February 28, 2022 are shown below:

	Fund Level	Private Investment Class	Personal Investment Class	Reserve Class	Resource Class
Invesco Premier Portfolio	$45,340	$187	$22,229	$45	$2,447

The Trust has entered into a master administrative services agreement with Invesco to provide accounting services to the Fund. The Trust has also entered into a transfer agency and service agreement with Invesco Investment Services, Inc. (“IIS”) to provide transfer agency and shareholder services to the Fund. Invesco and IIS do not charge the Fund any fees under these agreements. Also, Invesco has entered into a sub-administration agreement whereby The Bank of New York Mellon (“BNY Mellon”) serves as fund accountant and provides certain administrative services to the Fund. Pursuant to a custody agreement with the Trust on behalf of the Fund, BNY Mellon also serves as the Fund’s custodian.

The Trust has entered into master distribution agreements with IDI to serve as the distributor for the Investor Class, Institutional Class, Personal Investment Class, Private Investment Class, Reserve Class and Resource Class shares. The Trust has adopted plans pursuant to Rule 12b-1 under the 1940 Act with respect to the Fund’s Personal Investment Class, Private Investment Class, Reserve Class and Resource Class shares (collectively, the “Plans”). The Fund, pursuant to the Plans, pays IDI compensation at the annual rate of 0.55% of the Fund’s average daily net assets of Personal Investment Class shares, 0.30% of the average daily net assets of Private Investment Class shares, 0.87% of the average daily net assets of Reserve Class shares and 0.16% of the average daily net assets of Resource Class shares. The fees are accrued daily and paid monthly. Of the Plan payments, up to 0.25% of the average daily net assets of each class of shares may be paid to furnish continuing personal shareholder services to customers who purchase and own shares of such class. Any amounts not paid as a service fee under the Plans would constitute an asset-based sales charge. Rules of the Financial Industry Regulatory Authority (“FINRA”) impose a cap on the total sales charges, including asset-based sales charges, that may be paid by any class of shares of the Fund. For the six months ended February 28, 2022, expenses incurred under the plans are shown in the Statement of Operations as Distribution fees.

Certain officers and trustees of the Trust are officers and directors of the Adviser, IIS and/or IDI.

NOTE 3–Additional Valuation Information

GAAP defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date, under current market conditions. GAAP establishes a hierarchy that prioritizes the inputs to valuation methods, giving the highest priority to readily available unadjusted quoted prices in an active market for identical assets (Level 1) and the lowest priority to significant unobservable inputs (Level 3), generally when market prices are not readily available or are unreliable. Based on the valuation inputs, the securities or other investments are tiered into one of three levels. Changes in valuation methods may result in transfers in or out of an investment’s assigned level:

Level 1 –	Prices are determined using quoted prices in an active market for identical assets.
Level 2 –	Prices are determined using other significant observable inputs. Observable inputs are inputs that other market participants may use in pricing a security. These may include quoted prices for similar securities, interest rates, prepayment speeds, credit risk, yield curves, loss severities, default rates, discount rates, volatilities and others.
Level 3 –	Prices are determined using significant unobservable inputs. In situations where quoted prices or observable inputs are unavailable (for example, when there is little or no market activity for an investment at the end of the period), unobservable inputs may be used. Unobservable inputs reflect the Fund’s own assumptions about the factors market participants would use in determining fair value of the securities or instruments and would be based on the best available information.

As of February 28, 2022, all of the securities in the Fund were valued based on Level 2 inputs (see the Schedule of Investments for security categories). The level assigned to the securities valuations may not be an indication of the risk or liquidity associated with investing in those securities. Because of the inherent uncertainties of valuation, the values reflected in the financial statements may materially differ from the value received upon actual sale of those investments.

NOTE 4–Security Transactions with Affiliated Funds

The Fund is permitted to purchase or sell securities from or to certain other Invesco Funds under specified conditions outlined in procedures adopted by the Board of Trustees of the Trust. The procedures have been designed to ensure that any purchase or sale of securities by the Fund from or to another fund or portfolio that is or could be considered an affiliate by virtue of having a common investment adviser (or affiliated investment advisers), common Trustees and/or common officers complies with Rule 17a-7 of the 1940 Act. Further, as defined under the procedures, each transaction is effected at the current market price. Pursuant to these procedures, for the six months ended February 28, 2022, the Fund engaged in securities purchases of $115,591,084 and securities sales of $84,848,987, which did not result in any net realized gains (losses).

NOTE 5–Trustees’ and Officers’ Fees and Benefits

Remuneration is paid to certain Trustees and Officers of the Trust. Trustees have the option to defer their compensation. Those Trustees who defer compensation have the option to select various Invesco Funds in which their deferral accounts shall be deemed to be invested.

Certain current Trustees were eligible to participate in a retirement plan that provided for benefits to be paid upon retirement to Trustees over a period of time based on the number of years of service. The Fund may have certain former Trustees that also participate in a retirement plan and receive benefits under such plan. The Fund’s allocable portion of the remuneration paid to the Trustees, including its allocable portion of the fees and benefits of the deferred compensation plan and retirement plan are paid by Invesco and not by the Trust.

13 AIM Treasurer’s Series Trust (Invesco Treasurer’s Series Trust)

NOTE 6–Cash Balances

The Fund is permitted to temporarily overdraft or leave balances in its account with BNY Mellon, the custodian bank. Such balances, if any at period-end, are shown in the Statement of Assets and Liabilities under the payable caption Amount due custodian. To compensate BNY Mellon or the Fund for such activity, the Fund may either (1) pay to or receive from BNY Mellon compensation at a rate agreed upon by BNY Mellon and Invesco, not to exceed the contractually agreed upon rate; or (2) leave funds or overdraft funds as a compensating balance in the account so BNY Mellon or the Fund can be compensated for use of funds.

NOTE 7–Tax Information

The amount and character of income and gains to be distributed are determined in accordance with income tax regulations, which may differ from GAAP. Reclassifications are made to the Fund’s capital accounts to reflect income and gains available for distribution (or available capital loss carryforward) under income tax regulations. The tax character of distributions paid during the year and the tax components of net assets will be reported at the Fund’s fiscal year-end.

Capital loss carryforward is calculated and reported as of a specific date. Results of transactions and other activity after that date may affect the amount of capital loss carryforward actually available for the Fund to utilize. The ability to utilize capital loss carryforwards in the future may be limited under the Internal Revenue Code and related regulations based on the results of future transactions.

The Fund did not have any capital loss carryforward as of August 31, 2021.

Calculating your ongoing Fund expenses

Example

As a shareholder in the Personal Investment Class, you incur ongoing costs, including management fees, distribution and/or service (12b-1) fees and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period September 1, 2021 through February 28, 2022.

Actual expenses

The table below provides information about actual account values and actual expenses. You may use the information in this table, together with the amount you invested, to estimate the expenses that you paid over the period. 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 in the table under the heading entitled “Actual Expenses Paid During Period” to estimate the expenses you paid on your account during this period.

Hypothetical example for comparison purposes

The table below also provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return.

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 the 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 transaction costs, such as sales charges (loads) on purchase payments or contingent deferred sales charges on redemptions, if any. Therefore, the hypothetical information 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 transaction costs were included, your costs would have been higher.

		ACTUAL		HYPOTHETICAL (5% annual return before expenses)
Personal Investment   Class	Beginning Account Value (09/01/21)	Ending Account Value (02/28/22)1	Expenses Paid During Period2	Ending Account Value (02/28/22)	Expenses Paid During Period2	Annualized Expense Ratio
Invesco Premier Portfolio	$1,000.00	$1,000.10	$0.84	$1,023.95	$0.85	0.17%

¹  The actual ending account value is based on the actual total return of the Fund for the period September 1, 2021 through February 28, 2022, after actual expenses and will differ from the hypothetical ending account value which is based on the Fund’s expense ratio and a hypothetical annual return of 5% before expenses.

²  Expenses are equal to the Fund’s annualized expense ratio as indicated above multiplied by the average account value over the period, multiplied by 181/365 to reflect the most recent fiscal half year.

Weighted average maturity (WAM) is an average of the maturities of all securities held in the portfolio, weighted by each security’s percentage of net assets. The days to maturity for WAM is the lower of the stated maturity date or next interest rate reset date. WAM reflects how a portfolio would react to interest rate changes.     Weighted average life (WAL) is an average of all the maturities of all securities held in the portfolio, weighted by each security’s percentage of net assets. The days to maturity for WAL is the lower of the stated maturity date or next demand feature date. WAL reflects how a portfolio would react to deteriorating credit (widening spreads) or tightening liquidity conditions.

You could lose money by investing in the Fund. Although the Fund seeks to preserve your investment at $1.00 per share, it cannot guarantee it will do so. The Fund may impose a fee upon the sale of your shares or may temporarily suspend your ability to sell shares if the Fund’s liquidity falls below the 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.

Notes to Financial Statements

February 28, 2022

(Unaudited)

NOTE 1–Significant Accounting Policies

Invesco Premier Portfolio (the “Fund”) is a series of AIM Treasurer’s Series Trust (Invesco Treasurer’s Series Trust) (the “Trust”). The Trust is a Delaware statutory trust registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as an open-end series management investment company consisting of two separate portfolios and authorized to issue an unlimited number of shares of beneficial interest. The assets, liabilities and operations of the portfolio are accounted for separately. Information presented in these financial statements pertains only to the Fund. Matters affecting the portfolio or class will be voted on exclusively by the shareholders of such portfolio or class.

The Fund’s investment objective is to provide current income consistent with preservation of capital and liquidity.

The Fund currently consists of six classes of shares: Investor Class, Institutional Class, Private Investment Class, Personal Investment Class, Reserve Class and Resource Class. Investor Class shares of the Fund are available only to certain investors. Each class of shares is sold at net asset value.

The Fund is an investment company and accordingly follows the investment company accounting and reporting guidance in accordance with Financial Accounting Standards Board Accounting Standards Codification Topic 946, Financial Services – Investment Companies.

The Fund is a “retail money market fund” as defined in Rule 2a-7 under the 1940 Act, and seeks to maintain a stable or constant NAV of $1.00 per share using an amortized cost method of valuation. “Retail money market funds” are required to adopt policies and procedures reasonably designed to limit investments in the Fund to accounts beneficially owned by natural persons.

The Fund may impose a fee upon the sale of shares or may temporarily suspend the ability to sell shares if the Fund’s liquidity falls below required minimums or because of market conditions or other factors.

The following is a summary of the significant accounting policies followed by the Fund in the preparation of their financial statements.

A. Security Valuations – The Fund’s securities are recorded on the basis of amortized cost which approximates value as permitted by Rule 2a-7 under the 1940 Act. This method values a security at its cost on the date of purchase and, thereafter, assumes a constant amortization to maturity of any premiums or accretion of any discounts.

Because of the inherent uncertainties of valuation, the values reflected in the financial statements may materially differ from the value received upon actual sale of those investments.

The Fund may invest in securities that are subject to interest rate risk, meaning the risk that the prices will generally fall as interest rates rise and, conversely, the prices will generally rise as interest rates fall. Specific securities differ in their sensitivity to changes in interest rates depending on their individual characteristics. Changes in interest rates may result in increased market volatility, which may affect the value and/or liquidity of certain Fund investments.

B. Securities Transactions and Investment Income – Securities transactions are accounted for on a trade date basis. Realized gains or losses on sales are computed on the basis of specific identification of the securities sold. Interest income (net of withholding tax, if any) is recorded on the accrual basis from settlement date and includes coupon interest and amortization of premium and accretion of discount on debt securities as applicable.

The Fund may periodically participate in litigation related to the Fund’s investments. As such, the Fund may receive proceeds from litigation settlements involving each Fund’s investments. Any proceeds received are included in the Statements of Operations as realized gain (loss) for investments no longer held and as unrealized gain (loss) for investments still held.

Brokerage commissions and mark ups are considered transaction costs and are recorded as an increase to the cost basis of securities purchased and/or a reduction of proceeds on a sale of securities. Such transaction costs are included in the determination of net realized gain (loss) from investment securities reported in the Statement of Operations and the Statement of Changes in Net Assets and the net realized gains (losses) on securities per share in the Financial Highlights. Transaction costs are included in the calculation of the Fund’s net asset value and, accordingly, they reduce the Fund’s total returns. These transaction costs are not considered operating expenses and are not reflected in net investment income reported in the Statement of Operations and the Statement of Changes in Net Assets, or the net investment income per share and the ratios of expenses and net investment income reported in the Financial Highlights, nor are they limited by any expense limitation arrangements between the Fund and the investment adviser.

The Fund allocates realized capital gains and losses to a class based on the relative net assets of the class. The Fund allocates income to a class based on the relative value of the settled shares of the class.

C. Country Determination - For the purposes of making investment selection decisions and presentation in the Schedule of Investments, the investment adviser may determine the country in which an issuer is located and/or credit risk exposure based on various factors. These factors include the laws of the country under which the issuer is organized, where the issuer maintains a principal office, the country in which the issuer derives 50% or more of its total revenues and the country that has the primary market for the issuer’s securities, as well as other criteria. Among the other criteria that may be evaluated for making this determination are the country in which the issuer maintains 50% or more of its assets, the type of security, financial guarantees and enhancements, the nature of the collateral and the sponsor organization. Country of issuer and/or credit risk exposure has been determined to be the United States of America, unless otherwise noted.

D. Distributions - It is the policy of the Fund to declare dividends from net investment income daily and pay dividends on the first business day of the following month. The Fund generally distributes net realized capital gain (including net short-term capital gain), if any, annually.

E. Federal Income Taxes – The Fund intends to comply with the requirements of Subchapter M of the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), necessary to qualify as a regulated investment company and to distribute substantially all of the Fund’s taxable earnings to shareholders. As such, the Fund will not be subject to federal income taxes on otherwise taxable income (including net realized capital gain) that is distributed to shareholders. Therefore, no provision for federal income taxes is recorded in the financial statements.

The Fund recognizes the tax benefits of uncertain tax positions only when the position is more likely than not to be sustained. Management has analyzed the Fund’s uncertain tax positions and concluded that no liability for unrecognized tax benefits should be recorded related to uncertain tax positions. Management is not aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will change materially in the next 12 months.

11 AIM Treasurer’s Series Trust (Invesco Treasurer’s Series Trust)

The Fund files tax returns in the U.S. Federal jurisdiction and certain other jurisdictions. Generally, the Fund is subject to examinations by such taxing authorities for up to three years after the filing of the return for the tax period.

F. Expenses - Fees provided for under the Rule 12b-1 plan of a particular class of the Fund and which are directly attributable to that class are charged to the operations of such class. All other expenses are allocated among the classes based on relative net assets.

G. Accounting Estimates - The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period including estimates and assumptions related to taxation. Actual results could differ from those estimates by a significant amount. In addition, the Fund monitors for material events or transactions that may occur or become known after the period-end date and before the date the financial statements are released to print.

H. Indemnifications - Under the Trust’s organizational documents, each Trustee, officer, employee or other agent of the Trust is indemnified against certain liabilities that may arise out of the performance of their duties to the Fund. Additionally, in the normal course of business, the Fund enters into contracts, including the Fund’s servicing agreements, that contain a variety of indemnification clauses. The Fund’s maximum exposure under these arrangements is unknown as this would involve future claims that may be made against such Fund that have not yet occurred. The risk of material loss as a result of such indemnification claims is considered remote.

I. Repurchase Agreements - The Fund may enter into repurchase agreements. Collateral on repurchase agreements, including the Fund’s pro-rata interest in joint repurchase agreements, is taken into possession by the Fund upon entering into the repurchase agreement. Collateral consisting of U.S. Government Securities and U.S. Government Sponsored Agency Securities is marked to market daily to ensure its market value is at least 102% of the sales price of the repurchase agreement. Collateral consisting of non-government securities is marked to market daily to ensure its market value is at least 105% of the sales price of the repurchase agreement. The investments in some repurchase agreements, pursuant to procedures approved by the Board of Trustees, are through participation with other mutual funds, private accounts and certain non-registered investment companies managed by the investment advisor or its affiliates (“Joint repurchase agreements”). The principal amount of the repurchase agreement is equal to the value at period-end. If the seller of a repurchase agreement fails to repurchase the security in accordance with the terms of the agreement, the Fund might incur expenses in enforcing its rights, and could experience losses, including a decline in the value of the collateral and loss of income.

J. Other Risks - The effect on performance from investing in securities issued or guaranteed by companies in the banking and financial services industries will depend to a greater extent on the overall condition of those industries. Financial services companies are highly dependent on the supply of short-term financing. The value of securities of issuers in the banking and financial services industry can be sensitive to changes in government regulation and interest rates and to economic downturns in the United States and abroad.

U.S. dollar-denominated securities carrying foreign credit exposure may be affected by unfavorable political, economic or governmental developments that could affect payments of principal and interest.

K. COVID-19 Risk - The COVID-19 strain of coronavirus has resulted in instances of market closures and dislocations, extreme volatility, liquidity constraints and increased trading costs. Efforts to contain its spread have resulted in travel restrictions, disruptions of healthcare systems, business operations (including business closures) and supply chains, layoffs, lower consumer demand and employee availability, and defaults and credit downgrades, among other significant economic impacts that have disrupted global economic activity across many industries. Such economic impacts may exacerbate other pre-existing political, social and economic risks locally or globally and cause general concern and uncertainty.

    The full economic impact and ongoing effects of COVID-19 (or other future epidemics or pandemics) at the macro-level and on individual businesses are unpredictable and may result in significant and prolonged effects on the Fund’s performance.

NOTE 2–Advisory Fees and Other Fees Paid to Affiliates

The Trust has entered into a master investment advisory agreement with Invesco Advisers, Inc. (the “Adviser” or “Invesco”). Under the terms of the investment advisory agreement, the Fund accrues daily and pays monthly an advisory fee to the Adviser at an annual rate of 0.25% of the Fund’s average daily net assets. Pursuant to the master investment advisory agreement, the Adviser bears all expenses incurred by the Fund in connection with its operations, except for (1) interest, taxes and extraordinary items such as litigation costs; (2) brokers’ commissions, issue and transfer taxes, and other costs chargeable to the Fund in connection with securities transactions to which the Fund is a party or in connection with securities owned by the Fund; and (3) other expenditures which are capitalized in accordance with generally accepted accounting principles applicable to investment companies.

Under the terms of a master sub-advisory agreement between the Adviser to the Fund and each of Invesco Asset Management Deutschland GmbH, Invesco Asset Management Limited, Invesco Asset Management (Japan) Limited, Invesco Hong Kong Limited, Inc., Invesco Senior Secured Management, Inc. and Invesco Canada Ltd. and separate sub-advisory agreements with Invesco Capital Management LLC and Invesco Asset Management (India) Private Limited (collectively, the “Affiliated Sub-Advisers”) the Adviser, not the Fund, will pay 40% of the fees paid to the Adviser to any such Affiliated Sub-Adviser(s) that provide(s) discretionary investment management services to the Fund based on the percentage of assets allocated to such Sub-Adviser(s).

The Adviser has contractually agreed, through at least December 31, 2022, to waive advisory fees equal to 0.07% of the average daily net assets of the Fund.

For the six months ended February 28, 2022, the Adviser waived advisory fees and/or reimbursed Fund expenses in the following amounts:

Invesco Premier Portfolio $394,901

12 AIM Treasurer’s Series Trust (Invesco Treasurer’s Series Trust)

Further, Invesco and/or Invesco Distributors, Inc. (“IDI”) voluntarily waived fees and/or reimbursed expenses in order to increase the yields of the Fund. Voluntary fee waivers and/or reimbursements may be modified or discontinued at any time upon consultation with the Board of Trustees without further notice to investors. Voluntary fee waivers for the six months ended February 28, 2022 are shown below:

		Private	Personal
		Investment	Investment	Reserve	Resource
	Fund Level	Class	Class	Class	Class
Invesco Premier Portfolio	$45,340	$187	$22,229	$45	$2,447

The Trust has entered into a master administrative services agreement with Invesco to provide accounting services to the Fund. The Trust has also entered into a transfer agency and service agreement with Invesco Investment Services, Inc. (“IIS”) to provide transfer agency and shareholder services to the Fund. Invesco and IIS do not charge the Fund any fees under these agreements. Also, Invesco has entered into a sub-administration agreement whereby The Bank of New York Mellon (“BNY Mellon”) serves as fund accountant and provides certain administrative services to the Fund. Pursuant to a custody agreement with the Trust on behalf of the Fund, BNY Mellon also serves as the Fund’s custodian.

The Trust has entered into master distribution agreements with IDI to serve as the distributor for the Investor Class, Institutional Class, Personal Investment Class, Private Investment Class, Reserve Class and Resource Class shares. The Trust has adopted plans pursuant to Rule 12b-1 under the 1940 Act with respect to the Fund’s Personal Investment Class, Private Investment Class, Reserve Class and Resource Class shares (collectively, the “Plans”). The Fund, pursuant to the Plans, pays IDI compensation at the annual rate of 0.55% of the Fund’s average daily net assets of Personal Investment Class shares, 0.30% of the average daily net assets of Private Investment Class shares, 0.87% of the average daily net assets of Reserve Class shares and 0.16% of the average daily net assets of Resource Class shares. The fees are accrued daily and paid monthly. Of the Plan payments, up to 0.25% of the average daily net assets of each class of shares may be paid to furnish continuing personal shareholder services to customers who purchase and own shares of such class. Any amounts not paid as a service fee under the Plans would constitute an asset-based sales charge. Rules of the Financial Industry Regulatory Authority (“FINRA”) impose a cap on the total sales charges, including asset-based sales charges, that may be paid by any class of shares of the Fund. For the six months ended February 28, 2022, expenses incurred under the plans are shown in the Statement of Operations as Distribution fees.

Certain officers and trustees of the Trust are officers and directors of the Adviser, IIS and/or IDI.

NOTE 3–Additional Valuation Information

GAAP defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date, under current market conditions. GAAP establishes a hierarchy that prioritizes the inputs to valuation methods, giving the highest priority to readily available unadjusted quoted prices in an active market for identical assets (Level 1) and the lowest priority to significant unobservable inputs (Level 3), generally when market prices are not readily available or are unreliable. Based on the valuation inputs, the securities or other investments are tiered into one of three levels. Changes in valuation methods may result in transfers in or out of an investment’s assigned level:

Level 1 –	Prices are determined using quoted prices in an active market for identical assets.
Level 2 –	Prices are determined using other significant observable inputs. Observable inputs are inputs that other market participants may use in pricing a security. These may include quoted prices for similar securities, interest rates, prepayment speeds, credit risk, yield curves, loss severities, default rates, discount rates, volatilities and others.
Level 3 –	Prices are determined using significant unobservable inputs. In situations where quoted prices or observable inputs are unavailable (for example, when there is little or no market activity for an investment at the end of the period), unobservable inputs may be used. Unobservable inputs reflect the Fund’s own assumptions about the factors market participants would use in determining fair value of the securities or instruments and would be based on the best available information.

As of February 28, 2022, all of the securities in the Fund were valued based on Level 2 inputs (see the Schedule of Investments for security categories). The level assigned to the securities valuations may not be an indication of the risk or liquidity associated with investing in those securities. Because of the inherent uncertainties of valuation, the values reflected in the financial statements may materially differ from the value received upon actual sale of those investments.

NOTE 4–Security Transactions with Affiliated Funds

The Fund is permitted to purchase or sell securities from or to certain other Invesco Funds under specified conditions outlined in procedures adopted by the Board of Trustees of the Trust. The procedures have been designed to ensure that any purchase or sale of securities by the Fund from or to another fund or portfolio that is or could be considered an affiliate by virtue of having a common investment adviser (or affiliated investment advisers), common Trustees and/or common officers complies with Rule 17a-7 of the 1940 Act. Further, as defined under the procedures, each transaction is effected at the current market price. Pursuant to these procedures, for the six months ended February 28, 2022, the Fund engaged in securities purchases of $115,591,084 and securities sales of $84,848,987, which did not result in any net realized gains (losses).

NOTE 5–Trustees’ and Officers’ Fees and Benefits

Remuneration is paid to certain Trustees and Officers of the Trust. Trustees have the option to defer their compensation. Those Trustees who defer compensation have the option to select various Invesco Funds in which their deferral accounts shall be deemed to be invested.

Certain current Trustees were eligible to participate in a retirement plan that provided for benefits to be paid upon retirement to Trustees over a period of time based on the number of years of service. The Fund may have certain former Trustees that also participate in a retirement plan and receive benefits under such plan. The Fund’s allocable portion of the remuneration paid to the Trustees, including its allocable portion of the fees and benefits of the deferred compensation plan and retirement plan are paid by Invesco and not by the Trust.

13 AIM Treasurer’s Series Trust (Invesco Treasurer’s Series Trust)

NOTE 6–Cash Balances

The Fund is permitted to temporarily overdraft or leave balances in its account with BNY Mellon, the custodian bank. Such balances, if any at period-end, are shown in the Statement of Assets and Liabilities under the payable caption Amount due custodian. To compensate BNY Mellon or the Fund for such activity, the Fund may either (1) pay to or receive from BNY Mellon compensation at a rate agreed upon by BNY Mellon and Invesco, not to exceed the contractually agreed upon rate; or (2) leave funds or overdraft funds as a compensating balance in the account so BNY Mellon or the Fund can be compensated for use of funds.

NOTE 7–Tax Information

The amount and character of income and gains to be distributed are determined in accordance with income tax regulations, which may differ from GAAP. Reclassifications are made to the Fund’s capital accounts to reflect income and gains available for distribution (or available capital loss carryforward) under income tax regulations. The tax character of distributions paid during the year and the tax components of net assets will be reported at the Fund’s fiscal year-end.

Capital loss carryforward is calculated and reported as of a specific date. Results of transactions and other activity after that date may affect the amount of capital loss carryforward actually available for the Fund to utilize. The ability to utilize capital loss carryforwards in the future may be limited under the Internal Revenue Code and related regulations based on the results of future transactions.

The Fund did not have any capital loss carryforward as of August 31, 2021.

^(a)  There are entities that are record owners of more than 5% of the outstanding shares of the Fund and in the aggregate own 71% of the outstanding shares of the Fund. IDI has an agreement with these entities to sell Fund shares. The Fund, Invesco and/or Invesco affiliates may make payments to these entities, which are considered to be related to the Fund, for providing services to the Fund, Invesco and/or Invesco affiliates including but not limited to services such as securities brokerage, distribution, third party record keeping and account servicing. The Fund has no knowledge as to whether all or any portion of the shares owned of record by these entities are also owned beneficially.

Calculating your ongoing Fund expenses

Example

As a shareholder in the Reserve Class, you incur ongoing costs, including management fees, distribution and/or service (12b-1) fees and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period September 1, 2021 through February 28, 2022.

Actual expenses

The table below provides information about actual account values and actual expenses. You may use the information in this table, together with the amount you invested, to estimate the expenses that you paid over the period. 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 in the table under the heading entitled “Actual Expenses Paid During Period” to estimate the expenses you paid on your account during this period.

Hypothetical example for comparison purposes

The table below also provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return.

    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 the 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 transaction costs, such as sales charges (loads) on purchase payments or contingent deferred sales charges on redemptions, if any. Therefore, the hypothetical information 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 transaction costs were included, your costs would have been higher.

		ACTUAL		HYPOTHETICAL (5% annual return before expenses)
	Beginning	Ending	Expenses	Ending	Expenses	Annualized
	Account Value	Account Value	Paid During	Account Value	Paid During	Expense
Reserve Class	(09/01/21)	(02/28/22)1	Period2	(02/28/22)	Period2	Ratio
Invesco Premier	$1,000.00	$1,000.10	$0.84	$1,023.95	$0.85	0.17%
Portfolio

¹  The actual ending account value is based on the actual total return of the Fund for the period September 1, 2021 through February 28, 2022, after actual expenses and will differ from the hypothetical ending account value which is based on the Fund’s expense ratio and a hypothetical annual return of 5% before expenses.

²  Expenses are equal to the Fund’s annualized expense ratio as indicated above multiplied by the average account value over the period, multiplied by 181/365 to reflect the most recent fiscal half year.

(a) As of April 19, 2022, an evaluation was performed under the supervision and with the participation of the officers of the Registrant, including the Principal Executive Officer (“PEO”) and Principal Financial Officer (“PFO”), to assess the effectiveness of the Registrant’s disclosure controls and procedures, as that term is defined in Rule 30a-3(c) under the Investment Company Act of 1940 (“Act”), as amended. Based on that evaluation, the Registrant’s officers, including the PEO and PFO, concluded that, as of April 19, 2022, the Registrant’s disclosure controls and procedures were reasonably designed so as to ensure: (1) that information required to be disclosed by the Registrant on Form N-CSR is recorded, processed, summarized and reported within the time periods specified by the rules and forms of the Securities and Exchange Commission; and (2) that material information relating to the Registrant is made known to the PEO and PFO as appropriate to allow timely decisions regarding required disclosure.

(b) There have been no changes in the Registrant’s internal control over financial reporting (as defined in Rule 30a-3(d) under the Act) that occurred during the period covered by this report that have materially affected, or are reasonably likely to materially affect, the Registrant’s internal control over financial reporting.
