Distribution and/or Service (12b-1) Fees reflect actual fees as of the Fund's most recent fiscal year end.

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 the same.

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	658$	886$	1,133$	1,838$
Class C	291$	591$	1,016$	2,003$
Class R	140$	437$	755$	1,657$
Class Y	90$	281$	488$	1,084$
Class R5	82$	255$	444$	990$
Class R6	82$	255$	444$	990$

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

	1 Year	3 Years	5 Years	10 Years
Class A	658$	886$	1,133$	1,838$
Class C	191$	591$	1,016$	2,003$
Class R	140$	437$	755$	1,657$
Class Y	90$	281$	488$	1,084$
Class R5	82$	255$	444$	990$
Class R6	82$	255$	444$	990$

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 28% of the average value of its portfolio.

Principal Investment Strategies of the Fund

The Fund invests primarily in common stock of U.S. companies of any market capitalization size. The Fund may also invest in securities of foreign issuers.

While the process may change over time or vary in particular cases, in general the selection process currently uses a fundamental approach in analyzing issuers on factors such as a company’s financial performance, company strength and prospects, industry position, and business model and

1        Invesco Main Street All Cap Fund®

invesco.com/usO-MSA-SUMPRO-1  

management strength. Industry outlook, market trends and general economic conditions may also be considered. The portfolio is constructed and regularly monitored based upon several analytical tools, including quantitative investment models. Quantitative models are used as part of the idea generation process to rank securities within each sector to identify potential buy and sell candidates for further fundamental analysis.

The Fund aims to maintain a diversified portfolio across major economic sectors by applying investment parameters for both sector and position size. The portfolio also includes both growth and value stocks. The portfolio managers may sell a security if the stock price is approaching its target; if there has been a deterioration in the company’s competitive position or poor execution by the company’s management; or if more attractive alter-native investment ideas have been identified.

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 which 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, 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.

Investing in Stocks Risk. The value of the Fund’s portfolio may be affected by changes in the stock markets. Stock markets may experience significant short-term volatility and may fall or rise sharply at times. Adverse events in any part of the equity or fixed-income markets may have unexpected negative effects on other market segments. Different stock markets may behave differently from each other and U.S. stock markets may move in the opposite direction from one or more foreign stock markets.

The prices of individual stocks generally do not all move in the same direction at the same time. However, individual stock prices tend to go up and down more dramatically than those of certain other types of investments, such as bonds. A variety of factors can negatively affect the price of a particular company’s stock. These factors may include, but are not limited to: poor earnings reports, a loss of customers, litigation against the company, general unfavorable performance of the company’s sector or industry, or changes in government regulations affecting the company or its industry. To the extent that securities of a particular type are emphasized (for example foreign stocks, stocks of small- or mid-cap companies, growth or value stocks, or stocks of companies in a particular industry), fund share values may fluctuate more in response to events affecting the market for those types of securities.

Small- and Mid-Capitalization Companies Risks. Investing in securities of small- and mid-capitalization companies involves greater risk than customarily is associated with investing in larger, more established companies. Stocks of small- and mid-capitalization companies tend to be more vulnerable to changing market conditions, may have little or no operating history or track record of success, and may have more limited product lines and markets, less experienced management and fewer financial resources than larger companies. These companies’ securities may be more volatile and less liquid than those of more established companies.

They may be more sensitive to changes in a company’s earnings expectations and may experience more abrupt and erratic price movements. Smaller companies’ securities often trade in lower volumes and in many instances, are traded over-the-counter or on a regional securities exchange, where the frequency and volume of trading is substantially less than is typical for securities of larger companies traded on national securities exchanges. Therefore, the securities of smaller companies may be subject to wider price fluctuations and it might be harder for the Fund to dispose of its holdings at an acceptable price when it wants to sell them. Since small- and mid-cap companies typically reinvest a high proportion of their earnings in their business, they may not pay dividends for some time, particularly if they are newer companies. It may take a substantial period of time to realize a gain on an investment in a small- or mid-cap company, if any gain is realized at all. The Fund measures the market capitalization of an issuer at the time of investment.

Risks of Growth Investing. If a growth company’s earnings or stock price fails to increase as anticipated, or if its business plans do not produce the expected results, the value of its securities may decline sharply. Growth companies may be newer or smaller companies that may experience greater stock price fluctuations and risks of loss than larger, more established companies. Newer growth companies tend to retain a large part of their earnings for research, development or investments in capital assets. Therefore, they may not pay any dividends for some time. Growth investing has gone in and out of favor during past market cycles and is likely to continue to do so. During periods when growth investing is out of favor or when markets are unstable, it may be more difficult to sell growth company securities at an acceptable price. Growth stocks may also be more volatile than other securities because of investor speculation.

Risks of Value Investing. Value investing entails the risk that if the market does not recognize that a selected security is undervalued, the prices of that security might not appreciate as anticipated. A value approach could also result in fewer investments that increase rapidly during times of market gains and could cause a fund to underperform funds that use a growth or non-value approach to investing. Value investing has gone in and out of favor during past market cycles and when value investing is out of favor or when markets are unstable, the securities of “value” companies may underperform the securities of “growth” companies.

Industry and Sector Focus. The Fund may from time to time have a significant amount of its assets invested in a particular industry or sector. The prices of stocks of issuers in a particular industry or sector may go up and down in response to changes in economic conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than others. To the extent that the Fund has a significant amount of its assets invested in a particular industry or sector, its share values may fluctuate in response to events affecting that industry or sector. To some extent that risk may be limited by the Fund’s policy of not concentrating its investments in any one industry.

Risks of Foreign Investing. Foreign securities are subject to special risks. Securities traded in foreign markets may be less liquid and more volatile than those traded in U.S. markets. Foreign issuers are usually not subject to the same accounting and disclosure requirements that U.S. companies are subject to, which may make it difficult for the Fund to evaluate a foreign company’s operations or financial condition. A change in the value of a foreign currency against the U.S. dollar will result in a change in the U.S. dollar value of investments denominated in that foreign currency and in the value of any income or distributions the Fund may receive on those investments. The value of foreign investments may be affected by exchange control regulations, foreign taxes, higher transaction and other costs, delays in the settlement of transactions, changes in economic or monetary policy in the United States or abroad, expropriation or nationalization of a company’s assets, or other political and economic factors. In addition, due to the inter-relationship of global economies and financial markets, changes in political and economic factors in one country or region could adversely affect conditions in another country or region.

2        Invesco Main Street All Cap Fund®

Investments in foreign securities may also expose the Fund to time-zone arbitrage risk. Foreign securities may trade on weekends or other days when the Fund does not price its shares. As a result, the value of the Fund’s net assets may change on days when you will not be able to purchase or redeem the Fund’s shares. At times, the Fund may emphasize investments in a particular country or region and may be subject to greater risks from adverse events that occur in that country or region. Foreign securities and foreign currencies held in foreign banks and securities depositories may be subject to only limited or no regulatory oversight.

Risks of Quantitative Models. The portfolio managers use quantitative models as part of the idea generation process. Quantitative models are based upon many factors that measure individual securities relative to each other. Such models, which can be adversely affected by errors or imperfections in the factors or the data on which measurements are based, any technical issues with construction or implementation of the model, or a failure to perform as expected, may not always identify securities that perform well in the future.

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 Main Street All Cap 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 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-based securities market benchmark. 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, Class R and Class Y  shares of the predecessor fund. Class A, Class C, Class R and Class Y  shares of the predecessor fund were reorganized into Class A, Class C, Class R and Class Y shares, respectively, of the Fund after the close of business on May 24, 2019. Class A, Class C, Class R and Class Y shares’ returns of the Fund will be different from the returns of the predecessor fund as they have different expenses. Class R5 and Class R6 shares’ returns of the Fund will be different from Class A shares’ returns of the Fund and the predecessor fund as they have different expenses. Performance for Class A shares has been restated to reflect the Fund’s applicable sales charge.

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 generally are taxable to you as ordinary income, capital gains, or some combination of both, unless you are investing through a tax-advantaged arrangement, such as a 401(k) plan, 529 college savings plan or individual retirement account. Any distributions from a 401(k) plan or individual retirement account may be taxed as ordinary income when withdrawn from such plan or account.

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.
