Beginning on January 1, 2021, as permitted by regulations adopted by the Securities and Exchange Commission, paper copies of the Fund's shareholder reports will no longer be sent by mail, unless you specifically request paper copies of the reports from the Fund or from your financial intermediary, such as a broker-dealer or bank. Instead, the reports will be made available on the Fund's website, and you will be notified by mail each time a report is posted and provided with a website link to access the report.

If you already elected to receive shareholder reports electronically, you will not be affected by this change and you need not take any action. You may elect to receive shareholder reports and other communications from the Fund electronically by contacting your financial intermediary (such as a broker-dealer or bank) or, if you are a direct investor, by enrolling at invesco.com/edelivery.

You may elect to receive all future reports in paper free of charge. If you invest through a financial intermediary, you can contact your financial intermediary to request that you continue to receive paper copies of your shareholder reports. If you invest directly with the Fund, you can call (800) 959-4246 to let the Fund know you wish to continue receiving paper copies of your shareholder reports. Your election to receive reports in paper will apply to all funds held with your financial intermediary or all funds held with the fund complex if you invest directly with the Fund.

This report must be accompanied or preceded by a currently effective Fund prospectus, which contains more complete information, including fees and expenses. Investors should read it carefully before investing.

Unless otherwise stated, information presented in this report is as of February 29, 2020, and is based on total net assets. Unless otherwise stated, all data provided by Invesco.

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 secu- rity's percentage of net assets. The days to maturity for WAL is the lower of the stated maturity date or next demand fea- ture date. WAL reflects how a portfolio would react to deteriorating credit (widening spreads) or tightening liquidity conditions.

Letters to Shareholders

Dear Fellow Shareholders:

As independent chair of the Invesco Funds Board, I can assure you that the members of the Board are strong advocates for the interests of investors in Invesco's mutual funds. We work hard to repre- sent your interests through oversight of the quality of the investment management services your funds receive and other matters important to your investment. This includes but is not limited

to: monitoring how the portfolio management teams of the Invesco funds are performing in light of changing economic and market conditions; assessing each portfolio management team's investment performance within the context of the investment strategy described in the fund's prospectus; and monitoring for potential conflicts of interests that may impact the nature of the services that your funds receive.

We believe one of the most important services we provide our fund shareholders is the annual review of the funds' advisory and sub-advisory contracts with Invesco Advisers and its affiliates. This review is required by the Investment Company Act of 1940 and focuses on the nature and quality of the services Invesco provides as the adviser to the Invesco funds and the reasonableness of the fees that it charges for those services. Each year, we spend months carefully reviewing information received from Invesco and a variety of independent sources, such as performance and fee data prepared by Lipper Inc. (a subsidiary of Broadridge Financial Solutions, Inc.), an independent, third-party firm widely recognized as a leader in its field. We also meet with our independent legal counsel and other independent advisers to review and help us assess the information that we have received. Our goal is to assure that you receive quality investment management services for a rea- sonable fee.

On behalf of the Board, we look forward to continuing to represent your interests and serving your needs.

Sincerely,

Bruce L. Crockett

Independent Chair

Invesco Funds Board of Trustees

Dear Shareholders:

This semiannual report covers the six-month reporting period ended February 29, 2020. As always, we thank you for investing with us. By investing in a combination of short-term securities and securi- ties with slightly longer maturities, each Fund continued to preserve safety of principal and maintain a relatively high level of liquidity while offering competitive returns.

After raising interest rates multiple times in 2018, the US Federal Reserve (the Fed) adopted a more accommodative monetary policy during 2019. During the six-month reporting period, the Fed cut the federal funds rate by 0.25% in September and October 2019, respectively. This left the fed- eral funds target range at 1.50% to 1.75% at the end of the reporting period. In the beginning of 2020, markets saw an increase in volatility as a result of the impact of the Coronavirus (COVID-19). This has caused the outlook for the Fed to shift from a neutral policy during 2020 to a higher possi-

bility of several rate cuts. Rate cuts by the Fed would likely cause yields on government money market funds to decrease as a result.

One of the major developments impacting money market funds and the money market industry during the reporting period was the volatility in the short-term funding markets. October 2019, the Fed directed the Federal Reserve Bank of New York Trading Desk (the Desk) to purchase $60 billion per month in short-term Treasury Bills at least into the second quarter of 2020 to maintain sufficient reserve balances. This resulted in the flattening of the US Treasury curve and the stabilization of the repur- chase agreement operations (repo) markets.

Invesco Global Liquidity is part of Invesco Ltd., one of the world's largest independent asset management companies. Invesco Global Liquidity takes a long-term approach to short-term investing. Our unrelenting focus on preservation of capital, daily liquid- ity and competitive yield is implemented through repeatable, time-tested processes.

Again, thank you for investing with us.

Sincerely,

Andrew Schlossberg

Head of the Americas,

Senior Managing Director, Invesco Ltd.

Notes to Financial Statements

February 29, 2020 (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, Invesco Premier U.S. Government Money Portfolio and Invesco Premier Tax-Exempt 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 Tax-Exempt Portfolio's investment objective is to provide tax-exempt income consistent with preservation of capital and 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 and Invesco Premier Tax-Exempt Portfolio currently consist of two classes of shares: Investor Class and Institutional Class. Investor Class shares of the Fund are offered only to certain grandfathered 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 Tax-Exempt Portfolio, an "institutional money market fund", prices and transacts in its shares at a floating net asset value ("NAV") reflecting the current market-based values of its portfolio securities, except as otherwise generally permitted for securities with remaining maturities of 60 days or less, which are valued at amortized cost. Rules and regulations also require Invesco Premier Tax-Exempt Portfolio to round its NAV to four decimal places (e.g., $1.0000).

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 and Invesco Premier Tax-Exempt 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 — Invesco Premier Tax-Exempt Portfolio's securities are fair valued using an evaluated quote provided by an independent pricing service approved by the Board of Trustees. Evaluated quotes provided by the pricing service may be determined without exclusive reliance on quoted prices, and may reflect appropriate factors such as institution-size trading in similar groups of securities, market information from brokers and dealers, developments related to specific securities, yield (for debt obligations), quality, type of issue, coupon rate (for debt obligations), maturity (for debt obligations), individual trading characteristics and other market data. Pricing services generally value debt obligations assuming orderly transactions of institutional round lot size, but a fund may hold or transact in the same securities in smaller, odd lot sizes. Odd lots often trade at lower prices than institutional round lots. Debt obligations are subject to interest rate and credit risks. In addition, all debt obligations involve some risk of default with respect to interest and/or principal payments.

Securities for which market quotations are not readily available or became unreliable are valued at fair value as determined in good faith by or under the supervision of the Trust's officers following procedures approved by the Board of Trustees. Issuer specific events, market trends, bid/ asked quotes of brokers and information providers and other market data may be reviewed in the course of making a good faith determination of a security's fair value.

Invesco Premier Portfolio and Invesco Premier U.S. Government Portfolio'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. Bond premiums and discounts are amortized and/or accreted over the lives of the respective securities.

The Funds may periodically participate in litigation related to each Fund's investments. As such, the Funds may receive proceeds from litigation settlements. 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.

23	AIM Treasurer's Series Trust (Invesco Treasurer's Series Trust)

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.

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.

In addition, Invesco Premier Tax-Exempt Portfolio intends to invest in such municipal securities to allow it to qualify to pay shareholders "exempt interest dividends", as defined in the Internal Revenue Code.

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.

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.

The value of, payment of interest on, repayment of principal for and the ability to sell a municipal security may be affected by constitutional amendments, legislative enactments, executive orders, administrative regulations, voter initiatives and the economics of the regions in which the issuers are located.

24	AIM Treasurer's Series Trust (Invesco Treasurer's Series Trust)

Since many municipal securities are issued to finance similar projects, especially those relating to education, health care, transportation and utilities, conditions in those sectors can affect the overall municipal securities market and each Fund's investments in municipal securities.

There is some risk that a portion or all of the interest received from certain tax-free municipal securities could become taxable as a result of determinations by the Internal Revenue Service.

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.

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.

Under the terms of a master sub-advisory agreement between the Adviser to each Fund other than Invesco Premier U.S. Government Money 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, for Invesco Premier Portfolio and Invesco Premier Tax-Exempt Portfolio, 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 Funds, 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 each Fund based on the percentage of assets allocated to such Sub-Adviser(s).

The Adviser has contractually agreed, through at least December 31, 2020, 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. In addition, the Adviser has contractually agreed, through at least December 31, 2020, to waive advisory fees equal to 0.05% of the average daily net assets of Invesco Premier Tax-Exempt Portfolio.

For the six-month period ended February 29, 2020, the Adviser waived advisory fees and/or reimbursed Fund expenses in the following amounts:

Invesco Premier Portfolio	$ 627,650
Invesco Premier U.S. Government Money Portfolio	3,229,317
Invesco Premier Tax-Exempt Portfolio	20,790

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 custodian and fund accountant and provides certain administrative services to the Funds.

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 classes. 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-month period ended February 29, 2020, 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.

25	AIM Treasurer's Series Trust (Invesco Treasurer's Series Trust)

As of February 29, 2020, 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 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-month period ended February 29, 2020, each Fund engaged in transactions with affiliates as listed below:

	Securities Purchases	Securities Sales	Net Realized Gains
Invesco Premier Portfolio	$86,957,327	$70,568,338	$-

Invesco Premier Tax-Exempt Portfolio	17,442,973	39,811,770	-

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 had a capital loss carryforward as of August 31, 2019, as follows:

	Not Subject to
Fund	Expiration	Total*
Invesco Premier U.S. Government Money Portfolio	$3,507	$3,507
Invesco Premier Tax-Exempt Portfolio	3,793	3,793

*Capital loss carryforwards are reduced for limitations, if any, to the extent required by the Internal Revenue Code and may be further limited depending upon a variety of factors, including the realization of net unrealized gains or losses as of the date of any reorganization.

NOTE 8—Investment Transactions

The aggregate cost and the net unrealized appreciation (depreciation) of investments for tax purposes are as follows:

		At February 29, 2020
				Net
				Unrealized
	Federal	Unrealized	Unrealized	Appreciation
	Tax Cost*	Appreciation	(Depreciation)	(Depreciation)
Invesco Premier Tax-Exempt Portfolio	$69,108,769	$117	$(1,066)	$(949)

*For Invesco Premier Portfolio, Invesco Premier U.S. Government Money Portfolio and Invesco Premier Tax-Exempt Portfolio, cost of investments are the same for tax and financial reporting purposes.

NOTE 10—Subsequent Event

During the first quarter of 2020, the World Health Organization declared the coronavirus (COVID-19) to be a public health emergency. COVID-19 has led to increased short-term market volatility and may have adverse long-term effects on U.S. and world economies and markets in general. COVID-19 may adversely impact the Funds' ability to achieve their investment objectives. Because of the uncertainties on valuation, the global economy and business operations, values reflected in these financial statements may materially differ from the value received upon actual sales of those investments.

The Coronavirus Aid, Relief, and Economic Security Act, commonly referred to as the "CARES Act," was signed into law on March 27, 2020 by President Trump. The Adviser is assessing the components of the Act, and the impacts to the Funds should be immaterial.

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, 2019 through February 29, 2020.

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.

1The actual ending account value is based on the actual total return of the Funds for the period September 1, 2019 through February 29, 2020, 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.

2Expenses are equal to each Fund's annualized expense ratio as indicated above multiplied by the average account value over the period, multiplied by 182/366 to reflect the most recent fiscal half year.

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, 2019 through February 29, 2020.

Actual expenses

Notes to Financial Statements

February 29, 2020 (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 three separate portfolios, the 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 offered only to certain grandfathered 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.

The Fund may periodically participate in litigation related to the Fund's investments. As such, the Fund may receive proceeds from litigation settlements. 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.

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

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

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.

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 - 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 Fund may not be able to recover its investment in such issuer from the U.S. Government.

There is some risk that a portion or all of the interest received from certain tax-free municipal securities could become taxable as a result of determinations by the Internal Revenue Service.

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, 2020, to waive advisory fees equal to 0.07% of the average daily net assets of the Fund.

For the six months ended February 29, 2020, the Adviser waived advisory fees of $627,650.

14	AIM Treasurer's Series Trust (Invesco Treasurer's Series Trust)

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 custodian and fund accountant and provides certain administrative services to the Fund.

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 the class of shares may be paid to furnish continuing personal shareholder services to customers who purchase and own shares of such classes. 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 29, 2020, 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

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

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 29, 2020, 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 29, 2020, the Fund engaged in securities purchases of $86,957,327 and securities sales of $70,568,338, which did not result in any net realized gains (losses).

NOTE 5—Trustees' and Officers' Fees and Benefits

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.

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.

15	AIM Treasurer's Series Trust (Invesco Treasurer's Series Trust)

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, 2019.

NOTE 9—Subsequent Event

During the first quarter of 2020, the World Health Organization declared the coronavirus (COVID-19) to be a public health emergency. COVID-19 has led to increased short-term market volatility and may have adverse long-term effects on U.S. and world economies and markets in general. COVID-19 may adversely impact the Fund's ability to achieve its investment objective. Because of the uncertainties on valuation, the global economy and business operations, values reflected in these financial statements may materially differ from the value received upon actual sales of those investments.

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, 2019 through February 29, 2020.

Actual expenses

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.

Portfolio

1The actual ending account value is based on the actual total return of the Fund for the period September 1, 2019 through February 29, 2020, 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.

2Expenses are equal to the Fund's annualized expense ratio as indicated above multiplied by the average account value over the period, multiplied by 182/366 to reflect the most recent fiscal half year.

Notes to Financial Statements

February 29, 2020 (Unaudited)

NOTE 1—Significant Accounting Policies

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

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

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.

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.

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

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.

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.

There is some risk that a portion or all of the interest received from certain tax-free municipal securities could become taxable as a result of determinations by the Internal Revenue Service.

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.

The Adviser has contractually agreed, through at least December 31, 2020, to waive advisory fees equal to 0.07% of the average daily net assets of the Fund.

For the six months ended February 29, 2020, the Adviser waived advisory fees of $627,650.

14	AIM Treasurer's Series Trust (Invesco Treasurer's Series Trust)

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 the class of shares may be paid to furnish continuing personal shareholder services to customers who purchase and own shares of such classes. 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 29, 2020, 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

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

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.

NOTE 4—Security Transactions with Affiliated Funds

NOTE 5—Trustees' and Officers' Fees and Benefits

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.

NOTE 6—Cash Balances

15	AIM Treasurer's Series Trust (Invesco Treasurer's Series Trust)

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, 2019.

NOTE 9—Subsequent Event

During the first quarter of 2020, the World Health Organization declared the coronavirus (COVID-19) to be a public health emergency. COVID-19 has led to increased short-term market volatility and may have adverse long-term effects on U.S. and world economies and markets in general. COVID-19 may adversely impact the Fund's ability to achieve its investment objective. Because of the uncertainties on valuation, the global economy and business operations, values reflected in these financial statements may materially differ from the value received upon actual sales of those investments.

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, 2019 through February 29, 2020.

Actual expenses

Hypothetical example for comparison purposes

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.

					HYPOTHETICAL
			ACTUAL		(5% annual return before expenses)

	Beginning	Ending		Expenses	Ending	Expenses	Annualized
Private Investment	Account Value	Account Value		Paid During	Account Value	Paid During	Expense

Invesco Premier	$1,000.00	$1,007.70		$2.40	$1,022.48	$2.41	0.48%
Portfolio

1The actual ending account value is based on the actual total return of the Fund for the period September 1, 2019 through February 29, 2020, 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.

Notes to Financial Statements

February 29, 2020 (Unaudited)

NOTE 1—Significant Accounting Policies

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

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

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.

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.

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

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.

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.

There is some risk that a portion or all of the interest received from certain tax-free municipal securities could become taxable as a result of determinations by the Internal Revenue Service.

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.

The Adviser has contractually agreed, through at least December 31, 2020, to waive advisory fees equal to 0.07% of the average daily net assets of the Fund.

For the six months ended February 29, 2020, the Adviser waived advisory fees of $627,650.

14	AIM Treasurer's Series Trust (Invesco Treasurer's Series Trust)

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 the class of shares may be paid to furnish continuing personal shareholder services to customers who purchase and own shares of such classes. 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 29, 2020, 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

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

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.

NOTE 4—Security Transactions with Affiliated Funds

NOTE 5—Trustees' and Officers' Fees and Benefits

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.

NOTE 6—Cash Balances

15	AIM Treasurer's Series Trust (Invesco Treasurer's Series Trust)

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, 2019.

NOTE 9—Subsequent Event

During the first quarter of 2020, the World Health Organization declared the coronavirus (COVID-19) to be a public health emergency. COVID-19 has led to increased short-term market volatility and may have adverse long-term effects on U.S. and world economies and markets in general. COVID-19 may adversely impact the Fund's ability to achieve its investment objective. Because of the uncertainties on valuation, the global economy and business operations, values reflected in these financial statements may materially differ from the value received upon actual sales of those investments.

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, 2019 through February 29, 2020.

Actual expenses

Hypothetical example for comparison purposes

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.

					HYPOTHETICAL
			ACTUAL		(5% annual return before expenses)

	Beginning	Ending		Expenses	Ending	Expenses	Annualized
Personal Investment	Account Value	Account Value		Paid During	Account Value	Paid During	Expense
Class	(09/01/19)	(02/29/20)1		Period2	(02/29/20)	Period2	Ratio
Invesco Premier	$1,000.00	$1,006.50		$3.64	$1,021.23	$3.67	0.73%
Portfolio

1The actual ending account value is based on the actual total return of the Fund for the period September 1, 2019 through February 29, 2020, 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.
