Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy, hold and sell shares of the Fund.

The table and Examples below do not reflect any transaction fees that may be charged by financial intermediaries or commissions that a shareholder may be required to pay directly to its financial intermediary when buying or selling Class Y or Class R6 shares. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $100,000 in the Invesco Funds. More information about these and other discounts is available from your financial professional and in the section "Shareholder Account Information - Initial Sales Charges (Class A Shares Only)" on page A-3 of the prospectus and the section "Purchase, Redemption and Pricing of Shares-Purchase and Redemption of Shares" on page L-1 of the statement of additional information (SAI).

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

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. This Example does not include commissions and/or other forms of compensation that investors may pay on transactions in Class Y and Class R6 shares. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain equal to the Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement in the first year and the Total Annual Fund Operating Expenses thereafter.

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

	1 Year	3 Years	5 Years	10 Years
Class A	$497	$684	$887	$1,472
Class C	$252	$505	$882	$1,741
Class Y	$50	$192	$346	$795
Class R6	$50	$175	$310	$706

You would pay the following expenses if you did not redeem your shares:

	1 Year	3 Years	5 Years	10 Years
Class A	$497	$684	$887	$1,472
Class C	$152	$505	$882	$1,741
Class Y	$50	$192	$346	$795
Class R6	$50	$175	$310	$706

Portfolio Turnover. The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 46% of the average value of its portfolio.

Principal Investment Strategies of the Fund

Under normal market conditions, and as a fundamental policy, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in securities the income from which, in the opinion of counsel to the issuer of each security, is exempt from regular federal individual income tax. The policy stated in the foregoing sentence may not be changed without shareholder approval of a majority of the Fund's outstanding voting securities, as defined in the Investment Company Act of 1940, as amended (1940 Act). In complying with this 80% investment requirement, the Fund may invest in derivatives and other instruments that have economic characteristics similar to the Fund's direct investments that are counted toward the 80% investment requirement.

Under normal market conditions, Invesco Advisers, Inc. (Invesco or the Adviser) seeks to achieve the Fund's investment objective by investing at least 80% of the Fund's net assets in investment grade municipal securities. Investment grade securities are: (i) securities rated BBB- or higher by S&P Global Ratings (S&P) or Baa3 or higher by Moody's Investors Service, Inc. (Moody's) or an equivalent rating by another nationally recognized statistical rating organization (NRSRO), (ii) securities with comparable short-term NRSRO ratings, or (iii) unrated securities determined by the Adviser to be of comparable quality, each at the time of purchase. If two or more NRSROs have assigned different ratings to a security, the Adviser uses the highest rating assigned.

Municipal securities include debt obligations of states, territories or possessions of the United States and the District of Columbia and their political subdivisions, agencies and instrumentalities, the interest on which is exempt from federal income tax at the time of issuance, in the opinion of bond counsel or other counsel to the issuers of such securities. The Fund can invest in municipal securities of any duration or maturity.

The Fund seeks to invest primarily in municipal securities issued by issuers involved in projects or technologies with high potential positive environmental impact, as determined by the Adviser using its proprietary evaluation system, in areas such as land, water and energy conservation. Generally, the Adviser views projects or technologies with high potential positive environmental impact to include opportunities likely to result in lower emissions, environmental conservation, environmental rehabilitation, increased use or creation of renewable energy, increased sustainability, or other positive environmental outcomes. These high potential opportunities are identified by the Adviser through a proprietary review process that takes into account published information about the issuer and its programs and policies, along with issue-level data, including issuer-level reviews that rely on the purpose/use of proceeds statement and source of funding, as described further below.

Shareholders will be provided with 60 days' notice of any strategy change resulting in consideration of environmental focused criteria no longer being material to the Fund's principal investment strategy.

The principal types of municipal debt securities purchased by the Fund are revenue obligations and general obligations. To meet its investment objective, the Fund invests in different types of general obligation and revenue obligation securities, including fixed and variable rate securities, municipal notes, variable rate demand notes, municipal leases, custodial receipts, and participation certificates. The Fund may also invest in other types of municipal securities.

Under normal market conditions, the Fund may invest up to 20% of its net assets in municipal securities below investment grade. These types of securities are commonly referred to as junk bonds. With respect to such investments, the Fund has not established any limit on the percentage of its portfolio that may be invested in securities in any one rating category.

The Fund may invest all or a substantial portion of its assets in municipal securities that are subject to the federal alternative minimum tax.

The Fund may invest more than 25% of its net assets in a segment of the municipal securities market with similar characteristics if the Adviser determines that the yields available from obligations in a particular segment justify the additional risks of a larger investment in such segment. The Fund may not, however, invest more than 25% of its net assets in industrial development revenue bonds issued for companies in the same industry.

The Fund may invest in securities that are subject to resale restrictions such as those contained in Rule 144A promulgated under the Securities Act of 1933, as amended. The Fund's investments may include securities that do not produce immediate cash income, such as zero coupon securities and payment-in-kind securities.

The Fund may purchase and sell securities on a when-issued and delayed delivery basis, which means that the Fund buys or sells a security with payment and delivery taking place in the future.

The Fund can invest in inverse floating rate municipal obligations issued in connection with tender option bond programs to generate leverage.

The Fund can invest in derivative instruments, including futures contracts and swap contracts. The Fund can use futures contracts, including interest rate futures, to reduce exposure to interest rate changes and to manage duration. The Fund can use swap contracts, including interest rate swaps, to hedge its exposure to interest rates, but may not enter into interest rate swaps with respect to more than 25% of its total assets.

The Fund can borrow money to purchase additional securities, another form of leverage. Although the amount of borrowing will vary from time to time, the amount of leveraging from borrowings will not exceed one-third of the Fund's total assets.

The Adviser actively manages the Fund's portfolio and adjusts the average maturity of portfolio investments based upon its expectations regarding the direction of interest rates and other economic factors. The Adviser seeks to identify those securities that it believes entail reasonable credit risk considered in relation to the Fund's investment policies.

In selecting securities that meet the Fund's environmental criteria, the Adviser uses a proprietary process to evaluate municipal securities in different sectors based on pre-determined environmental and sustainability factors by applying a review based on an investment's potential for positive environmental impact.

The Adviser evaluates the following for a particular bond issue to determine whether investments meet the Fund's standards for high potential positive environmental impact. Securities held by the Fund, other than municipal securities, are not evaluated under the Adviser's proprietary evaluation system.

The approach described above emphasizes investment opportunities related to energy efficiency, renewable energy (including solar, wind, geothermal, and hydropower), energy storage and related technologies and programs, mass transit, carbon sink conservation, carbon capture technologies (those that prevent carbon dioxide from entering the atmosphere), investments in issuers with positive environmental performance records based on metrics determined by the Adviser, and other projects or technologies intended to minimize man-made impacts on climate. The Adviser generally views projects or technologies with high potential positive environmental impact to include opportunities likely to result in lower emissions, environmental conservation, environmental rehabilitation, increased use or creation of renewable energy, increased sustainability, or other positive environmental outcomes which is determined by the Adviser's analysis of the issuer profile, use of proceeds and source of funding. The Adviser generally seeks to exclude investments that do not meet the standards for high potential positive environmental impact, subject to certain limited exceptions deemed appropriate in the Adviser's discretion and consistent with its evaluation process.

The Adviser also uses its extensive research capabilities to assess potential investments and considers several factors, including general market and economic conditions and interest rate, credit and prepayment risks. Each security is subjected to an in-depth credit analysis to evaluate the level of risk it presents. Issuers and investments that are ultimately deemed appropriate to meet the Fund's standards for high potential positive environmental impact are monitored on an ongoing basis and reviewed periodically to ensure that they continue to meet those standards. Decisions to purchase or sell securities are determined by the portfolio managers that factor in economic and credit-related fundamentals, potential for positive environmental impact, market supply and demand, market dislocations and situation-specific opportunities. The purchase or sale of securities may be related to a decision to alter the Fund's macro risk exposure (such as duration, yield curve positioning and sector exposure), a need to limit or reduce the Fund's exposure to a particular security or issuer, degradation of an issuer's credit quality or potential for positive environmental impact, or general liquidity needs of the Fund. The potential for realization of capital gains or losses resulting from possible changes in interest rates will not be a major consideration and frequency of portfolio turnover generally will not be a limiting factor if the Adviser considers it advantageous to purchase or sell securities.

Principal Risks of Investing in the Fund

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

Market Risk. The market values of the Fund's investments, and therefore the value of the Fund's shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund's investments may go up or down due to general market conditions that are not specifically related to the particular issuer, such as real or perceived adverse economic conditions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability, natural or environmental disasters, widespread disease or other public health issues, war, military conflict, acts of terrorism or adverse investor sentiment generally. During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.

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

Municipal Securities Risk. The risk of a municipal obligation generally depends on the financial and credit status of the issuer. Constitutional amendments, legislative enactments, executive orders, administrative regulations, voter initiatives, and the issuer's regional economic conditions may affect the municipal security's value, interest payments, repayment of principal and the Fund's ability to sell the security. Failure of a municipal security issuer to comply with applicable tax requirements may make income paid thereon taxable, resulting in a decline in the security's value. In addition, there could be changes in applicable tax laws or tax treatments that reduce or eliminate the current federal income tax exemption on municipal securities or otherwise adversely affect the current federal or state tax status of municipal securities.

Municipal Issuer Focus Risk. The municipal issuers in which the Fund invests may be located in the same geographic area or may pay their interest obligations from revenue of similar projects, such as hospitals, airports, utility systems and housing finance agencies. This may make the Fund's investments more susceptible to similar social, economic, political or regulatory occurrences, making the Fund more susceptible to experience a drop in its share price than if the Fund had been more diversified across issuers that did not have similar characteristics.

Environmental Focus Criteria Risk. Because the Fund evaluates environmental focus factors to assess and exclude certain investments for non-financial reasons, it may forego some market opportunities available to funds that do not use these factors. The securities of issuers that meet the Fund's criteria for high potential positive environmental impact may underperform similar issuers that do not meet that criteria or may

underperform the market as a whole. As a result, the Fund may underperform funds that do not screen or score issuers based on environmental focus factors or funds that use a different environmental focus evaluation methodology. Information used by the Fund to evaluate such factors may not be readily available, complete or accurate, which could negatively impact the Fund's ability to apply its methodology, which in turn could negatively impact the Fund's performance. In addition, the Fund's assessment of an issuer, based on the issuer's level of involvement in a particular industry or the issuer's potential for positive environmental impact, may differ from that of other funds or an investor. As a result, the issuers in the Fund's portfolio may not reflect the beliefs or values of any particular investor and may not be deemed to exhibit positive or favorable environmental focus characteristics if different metrics were used to evaluate them. Issuers who the Adviser believes will have a positive environmental impact, may not have the impact anticipated by the Adviser's analysis and could be considered as having a high environmental risk profile.

Changing Fixed Income Market Conditions Risk. The current low interest rate environment was created in part by the Federal Reserve Board (FRB) and certain foreign central banks keeping the federal funds and equivalent foreign rates near historical lows. Increases in the federal funds and equivalent foreign rates may expose fixed income markets to heightened volatility and reduced liquidity for certain fixed income investments, particularly those with longer maturities. In addition, decreases in fixed income dealer market-making capacity may also potentially lead to heightened volatility and reduced liquidity in the fixed income markets. As a result, the value of the Fund's investments and share price may decline. Changes in central bank policies could also result in higher than normal shareholder redemptions, which could potentially increase portfolio turnover and the Fund's transaction costs.

Medium- and Lower-Grade Municipal Securities Risk. Medium- and lower-grade municipal securities generally involve more volatility and greater risks, including credit, market, liquidity and management risks, than higher-grade securities. Furthermore, many issuers of medium- and lower-grade securities choose not to have a rating assigned to their obligations. As such, the Fund's portfolio may consist of a higher portion of unrated securities than an investment company investing solely in higher-grade securities. Unrated securities may not be as attractive to as many buyers as are rated securities, which may have the effect of limiting the Fund's ability to sell such securities at the desired price.

High Yield Debt Securities (Junk Bond) Risk. Investments in high yield debt securities ("junk bonds") and other lower-rated securities will subject the Fund to substantial risk of loss. These securities are considered to be speculative with respect to the issuer's ability to pay interest and principal when due, are more susceptible to default or decline in market value and are less liquid than investment grade debt securities. Prices of high yield debt securities tend to be very volatile.

Alternative Minimum Tax Risk. All or a portion of the Fund's otherwise tax-exempt income may be taxable to those shareholders subject to the federal alternative minimum tax.

Liquidity Risk. The Fund may be unable to sell illiquid investments at the time or price it desires and, as a result, could lose its entire investment in such investments. Liquid securities can become illiquid during periods of market stress. If a significant amount of the Fund's securities become illiquid, the Fund may not be able to timely pay redemption proceeds and may need to sell securities at significantly reduced prices.

Zero Coupon or Pay-In-Kind Securities Risk. The value, interest rates, and liquidity of non-cash paying instruments, such as zero coupon and pay-in-kind securities, are subject to greater fluctuation than other types of securities. The higher yields and interest rates on pay-in-kind securities reflect the payment deferral and increased credit risk associated with such instruments and that such investments may represent a higher credit risk than loans that periodically pay interest.

When-Issued, Delayed Delivery and Forward Commitment Risks.When-issued and delayed delivery transactions subject the Fund to market risk because the value or yield of a security at delivery may be more or less than the purchase price or yield generally available when delivery occurs, and counterparty risk because the Fund relies on the buyer or seller, as the case may be, to consummate the transaction. These transactions also have a leveraging effect on the Fund because the Fund commits to purchase securities that it does not have to pay for until a later date, which increases the Fund's overall investment exposure and, as a result, its volatility.

Variable-Rate Demand Notes Risk. The absence of an active secondary market for certain variable and floating rate notes could make it difficult to dispose of these instruments, which could result in a loss.

Inverse Floating Rate Obligations Risk. The price of inverse floating rate obligations (inverse floaters) is expected to decline when interest rates rise, and generally will decline further than the price of a bond with a similar maturity. The price of inverse floaters is typically more volatile than the price of bonds with similar maturities. These risks can be particularly high if leverage is used in the formula that determines the interest payable by the inverse floater. Leverage may make the Fund's returns more volatile and increase the risk of loss; and the value of, and income earned on, an inverse floater that has a higher degree of leverage are more likely to be eliminated entirely under adverse market conditions. Additionally, these securities may lose some or all of their principal and, in some cases, the Fund could lose money in excess of its investment.

Borrowing and Leverage Risk. The Fund can borrow up to one-third of the value of its total assets (including the amount borrowed) from banks, as permitted by the Investment Company Act of 1940. It can use those borrowings for a number of purposes, including for purchasing securities, which can create "leverage." In that case, changes in the value of the Fund's investments will have a larger effect on its share price than if it did not borrow. Borrowing results in interest payments to the lenders and related expenses. Borrowing for investment purposes might reduce the Fund's return if the yield on the securities purchased is less than those borrowing costs. The Fund may also borrow to meet redemption obligations, for temporary and emergency purposes, or to unwind or contribute to trusts in connection with the Fund's investment in inverse floaters (instruments also involving the use of leverage), as described in this prospectus. The Fund currently participates in a line of credit with certain other Invesco Funds for its borrowing.

Taxability Risk. The Fund's investments in municipal securities rely on the opinion of the issuer's bond counsel that the interest paid on those securities will not be subject to federal income tax. Tax opinions are generally provided at the time the municipal security is initially issued. However, tax opinions are not binding on the Internal Revenue Service or any court, and after the Fund buys a security, the Internal Revenue Service or a court may determine that a bond issued as tax-exempt should in fact be taxable and the Fund's dividends with respect to that bond might be subject to federal income tax. In addition, income from tax-exempt municipal securities could be declared taxable because of unfavorable changes in tax laws, adverse interpretations by the Internal Revenue Service or a court, or the non-compliant conduct of a bond issuer.

Derivatives Risk. The value of a derivative instrument depends largely on (and is derived from) the value of an underlying security, currency, commodity, interest rate, index or other asset (each referred to as an underlying asset). In addition to risks relating to the underlying assets, the use of derivatives may include other, possibly greater, risks, including counterparty, leverage and liquidity risks. Counterparty risk is the risk that the counterparty to the derivative contract will default on its obligation to pay the Fund the amount owed or otherwise perform under the derivative contract. Derivatives create leverage risk because they do not require payment up front equal to the economic exposure created by holding a position in the derivative. As a result, an adverse change in the value of the underlying asset could result in the Fund sustaining a loss that is substantially greater than the amount invested in the derivative or the

anticipated value of the underlying asset, which may make the Fund's returns more volatile and increase the risk of loss. Derivative instruments may also be less liquid than more traditional investments and the Fund may be unable to sell or close out its derivative positions at a desirable time or price. This risk may be more acute under adverse market conditions, during which the Fund may be most in need of liquidating its derivative positions. Derivatives may also be harder to value, less tax efficient and subject to changing government regulation that could impact the Fund's ability to use certain derivatives or their cost. Derivatives strategies may not always be successful. For example, derivatives used for hedging or to gain or limit exposure to a particular market segment may not provide the expected benefits, particularly during adverse market conditions.

Financial Markets Regulatory Risk. Policy changes by the U.S. government or its regulatory agencies and political events within the U.S. and abroad may, among other things, affect investor and consumer confidence and increase volatility in the financial markets, perhaps suddenly and to a significant degree, which may adversely impact the Fund's operations, universe of potential investment options, and return potential.

Management Risk. The Fund is actively managed and depends heavily on the Adviser's judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund's portfolio. The Fund could experience losses if these judgments prove to be incorrect. Additionally, legislative, regulatory, or tax developments may adversely affect management of the Fund and, therefore, the ability of the Fund to achieve its investment objective.

Performance Information

The bar chart and performance table provide an indication of the risks of investing in the Fund. The Fund has adopted the performance of the Oppenheimer Municipal Fund (the predecessor fund) as the result of a reorganization of the predecessor fund into the Fund, which was consummated after the close of business on May 24, 2019 (the "Reorganization"). Prior to September 4, 2020, the Fund employed a different investment strategy, and prior to October 15, 2018, the predecessor fund employed a different investment strategy. Therefore, the performance shown for periods prior to September 4, 2020 may have differed had the Fund's current investment strategy been in effect. Prior to the Reorganization, the Fund had not yet commenced operations. The bar chart shows changes in the performance of the predecessor fund and the Fund from year to year as of December 31. The performance table compares the predecessor fund's and the Fund's performance to that of a broad measure of market performance and another benchmark with characteristics relevant to the Fund. The Fund's (and the predecessor fund's) past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future.

The returns shown for periods ending on or prior to May 24, 2019 are those of the Class A, Class C and Class Y shares of the predecessor fund. Class A, Class C and Class Y shares of the predecessor fund were reorganized into Class A, Class C and Class Y shares, respectively, of the Fund after the close of business on May 24, 2019. Class A, Class C and Class Y shares' returns of the Fund will be different from the returns of the predecessor fund as they have different expenses. Performance for Class A shares has been restated to reflect the Fund's applicable sales charge.

Fund performance reflects any applicable fee waivers and expense reimbursements. Performance returns would be lower without applicable fee waivers and expense reimbursements.

Updated performance information is available on the Fund's website at www.invesco.com/us.

There are no minimum investment amounts for Class R6 shares held through retail omnibus accounts maintained by an intermediary, such as a broker, that (i) generally charges an asset-based fee or commission in addition to those described in this prospectus, and (ii) maintains Class R6 shares and makes them available to retail investors.

Tax Information

The Fund's distributions primarily are exempt from regular federal income tax. All or a portion of these distributions, however, may be subject to the federal alternative minimum tax and state and local taxes. The Fund also may make distributions that are taxable to you as ordinary income or capital gains.

Payments to Broker-Dealers and Other Financial Intermediaries

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