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.   *Prior to the close of business on May 24, 2019, the Fund’s name was Oppenheimer Rochester AMT-Free Municipal Fund.

Performance quoted is past performance and cannot guarantee comparable future results; current performance may be lower or higher. Visit invesco.com for the most recent month-end performance. Performance figures reflect reinvested distributions and changes in net asset value (NAV). Investment return and principal value will vary so that you may have a gain or a loss when you sell shares. Fund returns include changes in share price, reinvested distributions and a 4.25% maximum applicable sales charge except where “without sales charge” is indicated. As the result of a reorganization after the close of business on May 24, 2019, the returns of the Fund for periods on or prior to May 24, 2019 reflect performance of the Oppenheimer predecessor fund. Share class returns will differ from those of the predecessor fund as they have different expenses. Returns for periods of less than one year are not annualized. Returns do not consider capital gains or income taxes on an individual’s investment. See Fund prospectus and summary prospectus for more information on share classes and sales charges. Fund literature is available at invesco.com.

Performance quoted is past performance and cannot guarantee comparable future results; current performance may be lower or higher. Visit invesco.com for the most recent month-end performance. Performance figures reflect reinvested distributions and changes in net asset value (NAV). Investment return and principal value will vary so that you may have a gain or a loss when you sell shares. Performance shown at NAV does not include the applicable front-end sales charge, which would have reduced the performance. The current maximum initial sales charge for Class A shares is 4.25%, and the contingent deferred sales charge for Class C shares is 1% for the 1-year period. Class Y and Class R6 shares have no sales charge; therefore, performance is at NAV. Effective after the close of business on May 24, 2019, 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. Class R6 shares’ performance shown prior to the inception date is that of the predecessor fund’s Class A shares at NAV and includes the 12b-1 fees applicable to Class A shares. Class A shares’ performance reflects any applicable fee waivers and/or expense reimbursements. Returns shown for Class A, Class C, Class Y, and Class R6 shares are blended returns of the predecessor fund and the Fund. Share class returns will differ from those of the predecessor fund because of different expenses. See Fund prospectuses and summary prospectuses for more information on share classes, sales charges and new fee agreements, if any. Fund literature is available at invesco.com

The Fund’s performance is compared to the performance of the Bloomberg Barclays Municipal Bond Index, which is an index of a broad range of investment-grade municipal bonds that measures the performance of the general municipal bond market. The Fund’s performance is also compared to the U.S. Consumer Price Index, a non-securities index that measures changes in the inflation rate. Indices are unmanaged, and an investment cannot be made into an index. While index comparisons may be useful to provide a benchmark for the Fund’s performance, it must be noted that the Fund’s investments are not limited to the investments comprising the indices. Index performance includes reinvestment of income, but does not reflect transaction costs, fees, expenses or taxes. Index performance is shown for illustrative purposes only as a benchmark for the Fund’s performance and does not predict or depict performance of the Fund. The Fund’s performance reflects the effects of the Fund’s business and operating expenses.

Distribution yields for Class A shares are based on dividends of $0.022 for the 28-day accrual period ended July 23, 2019. The yield without sales charge for Class A shares is calculated by dividing annualized dividends by the Class A net asset value (NAV) on July 23, 2019; for the yield with charge, the denominator is the Class A maximum offering price on that date. Distribution yields for Class C and Y are annualized based on dividends of $0.0176 and $0.0234, respectively, for the 28-day accrual period ended July 23, 2019 and on the corresponding net asset values on that date.

Standardized yield is based on an SEC-standardized formula designed to approximate the Fund’s annualized hypothetical current income from securities less expenses for the 30-day period ended July 31, 2019 and that date’s maximum offering price (for Class A shares) or net asset value (for all other share classes). Each result is compounded semiannually and annualized. Falling share prices artificially increase yields. The unsubsidized standardized yield is computed under an SEC-standardized formula based on net income earned for the 30-day period ended July 31, 2019. The calculation excludes any expense reimbursements and thus may result in a lower yield.

Taxable equivalent yield is based on the standardized yield and the top 2019 federal tax rate of 40.8%. Calculations factor in the 3.8% tax on unearned income under the Patient Protection and Affordable Care Act, as applicable. A portion of the Fund’s distributions may be subject to tax; capital gains distributions are taxable as capital gains. Tax treatments of the Fund’s distributions and capital gains may vary by state; Invesco does not offer tax advice. Please consult your tax adviser for information regarding your own personal tax situation. This Report must be preceded or accompanied by a Fund prospectus.

Investments in tobacco settlement bonds, which are backed by the proceeds a state or territory receives from the 1998 national litigation settlement with tobacco manufacturers, may be vulnerable to economic and/or legislative events that affect issuers in a particular municipal market sector. Annual payments by MSA-participating manufacturers, for example, hinge on many factors, including annual domestic cigarette shipments, inflation and the relative market share of non-participating manufacturers. To date, we believe consumption figures remain within an acceptable range of the assumptions used to structure MSA bonds. Future MSA payments could be reduced if consumption were to fall more rapidly than originally forecast.

Before investing, investors should carefully read the prospectus and/or summary prospectus and carefully consider the investment objectives, risks, charges and expenses. For this and more complete information about the fund(s), investors should ask their advisors for a prospectus/summary prospectus or visit invesco. com/fundprospectus.

Shares of Invesco funds are not deposits or obligations of any bank, are not guaranteed by any bank, are not insured by the FDIC or any other agency, and involve investment risks, including the possible loss of the principal amount invested.

Fund Expenses

Fund Expenses. As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, which may include sales charges (loads) on purchase payments and/or contingent deferred sales charges on redemptions; and (2) ongoing costs, including management fees; distribution and service fees; and other Fund expenses. These examples are intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The examples are based on an investment of $1,000.00 invested at the beginning of the period and held for the entire 6-month period ended August 31, 2019.

Actual Expenses. The first section of the table provides information about actual account values and actual expenses. You may use the information in this section for the class of shares you hold, together with the amount you invested, to estimate the expense that you paid over the period. Simply divide your account value by $1,000.00 (for example, an $8,600.00 account value divided by $1,000.00 = 8.60), then multiply the result by the number in the first section under the heading entitled “Expenses Paid During 6 Months Ended August 31, 2019” to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes. The second section of the table provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio for each class of shares, and an assumed rate of return of 5% per year for each class 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 for the class of shares you hold with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as front-end or contingent deferred sales charges (loads). Therefore, the “hypothetical” section of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

1. Actual expenses paid for Class A, C and Y are equal to the Fund’s annualized expense ratio for that class, multiplied by the average account value over the period, multiplied by 184/366 (to reflect the one-half year period). Actual expenses paid for Class R6 are equal to the Fund’s annualized expense ratio for that class, multiplied by the average account value over the period, multiplied by 99/366 to reflect the period from after the close of business on May 24, 2019 (inception of offering) to August 31, 2019.

2. Hypothetical expenses paid for all classes are equal to the Fund’s annualized expense ratio for that class, multiplied by the average account value over the period, multiplied by 184/366 (to reflect the one-half year period).

Those annualized expense ratios, excluding indirect expenses from affiliated funds, based on the 6-month period ended August 31, 2019 for Classes A, C and Y and for the period from after the close of business on May 24, 2019 (inception of offering) to August 31, 2019 for Class R6 are as follows:
