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:

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 53% of the average value of its portfolio.
Principal Investment Strategies of the Fund
Under normal market conditions, the Fund will invest at least 80% of its net assets, including any borrowings for investment purposes, in securities of “small-cap” companies, and in derivatives and other instruments that have economic characteristics similar to such securities. The Fund considers a small-cap company to be one that has a market capitalization within the range of market capitalizations of the companies included in the Russell
1        Invesco Main Street Small Cap Fund®
invesco.com/usO-MSS-SUMPRO-1
2000® Index during the most recent 11-month period (based on month-end data) plus the most recent data during the current month. A company’s market capitalization is the value of its outstanding stock.
The Fund primarily invests in common stock but may also invest in other types of securities such as real estate investment trusts (“REITs”) or other securities that are consistent with its investment objective.
Although the Fund mainly invests in U.S. companies, it can invest in securities issued by companies or governments in any country; however, it does not currently intend to invest substantially in foreign securities.
The portfolio managers use fundamental research to select securities for the Fund’s portfolio. 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, competitive strength and prospects, industry position, and business model and management strength. Industry outlook, market trends and general economic conditions may also be considered.
The Fund aims to maintain a broad diversification across all major economic sectors. In constructing the portfolio, the Fund seeks to limit exposure to so-called “top-down” or “macro” risks, such as overall stock market movements, economic cycles, and interest rate or currency fluctuations. Instead, the portfolio managers seek to add value by selecting individual securities that they believe have superior company-specific fundamental attributes or relative valuations that they expect to outperform their industry and sector peers. This is commonly referred to as a “bottom-up” approach to portfolio construction.
The portfolio managers consider, among other things, stock rankings, benchmark weightings and capitalization outlooks in determining security weightings for individual issuers.
The portfolio managers might sell a security if, among other things, the price is approaching their price target, if the company’s competitive position has deteriorated or the company’s management has performed poorly, or if they have identified more attractive investment prospects.
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. These market conditions may include real or perceived adverse economic conditions, changes in trade regulation or economic sanctions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability and uncertainty, natural or environmental disasters, widespread disease or other public health issues, war, military conflict, acts of terrorism, economic crisis or adverse investor sentiment generally, among others. Certain changes in the U.S. economy in particular, such as when the U.S. economy weakens or when its financial markets decline, may have a material adverse effect on global financial markets as a whole, and on the securities to which the Fund has exposure. Increasingly strained relations between the U.S. and foreign countries, including as a result of economic sanctions and tariffs, may also adversely affect U.S. issuers, as well as non-U.S. issuers.
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 Risk. 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.
REIT Risk/Real Estate Risk. Investments in real estate related instruments may be adversely affected by economic, legal, cultural, environmental or technological factors that affect property values, rents or occupancies. Shares of real estate related companies, which tend to be small- and mid-cap companies, may be more volatile and less liquid than larger companies. If a real estate related company defaults on certain types of debt obligations held by the Fund, the Fund may acquire real estate directly, which involves additional risks such as environmental liabilities; difficulty in valuing and selling the real estate; and economic or regulatory changes.
Foreign Investment Risk. Investments in the securities of non-U.S. issuers involve risks beyond those associated with investments in U.S. securities. Foreign securities may have relatively low market liquidity, greater market volatility, decreased publicly available information and less reliable financial information about issuers, and inconsistent and potentially less stringent accounting, auditing and financial reporting requirements and standards of practice, including recordkeeping standards, comparable to those applicable to domestic issuers. Foreign securities also are subject to the risks of possible seizure, expropriation, nationalization, political or social instability, changes in economic or taxation policies or other adverse political or economic developments (in which the Fund could lose its entire investments in a certain market) and the difficulty of enforcing obligations in other countries, including the possible adoption of foreign governmental
2        Invesco Main Street Small Cap Fund®
invesco.com/usO-MSS-SUMPRO-1
restrictions such as exchange controls. Investments in foreign securities also may be subject to dividend withholding or confiscatory taxes, currency blockage and/or transfer restrictions and higher transactional costs. To the extent the Fund invests in securities denominated in foreign currencies, fluctuations in the value of the U.S. dollar relative to the values of other currencies may adversely affect investments in foreign securities and may negatively impact the Fund’s returns, unless the Fund has hedged its foreign currency exposure. Currency exchange rates may fluctuate significantly over short periods of time. Currency hedging strategies, if used, may not always be successful. Foreign companies generally may be subject to less stringent regulations than U.S. companies, including financial reporting requirements and auditing and accounting controls, and may therefore be more susceptible to fraud or corruption. There may be less public information available about foreign companies than U.S. companies, making it difficult to evaluate those foreign companies. From time to time, certain companies in which the Fund invests may operate in, or have dealings with, countries subject to sanctions or embargoes imposed by the U.S. government and the United Nations and/or in countries the U.S. government identified as state sponsors of terrorism. One or more of these companies may be subject to constraints under U.S. law or regulations that could negatively affect the company’s performance. Additionally, one or more of these companies could suffer damage to its reputation if the market identifies it as a company that invests or deals with countries that the U.S. government identifies as state sponsors of terrorism or is subject to sanctions.
Valuation Risk. The price the Fund could receive upon the sale of a portfolio investment may differ from the Fund’s valuation of the investment, particularly for investments that trade in thin or volatile markets or that are valued using a fair valuation methodology. Financial information related to securities of non-U.S. issuers may be less reliable than information related to securities of U.S. issuers, which may make it difficult to obtain a current price for a non-U.S. security held by the Fund. When market quotations are not readily available for Fund investments, those investments are fair valued by the Adviser. There are multiple methods that can be used to fair value a portfolio investment and such methods may involve more subjectivity than the use of market quotations. The value established for an investment through fair valuation may be different from what would be produced if the investment had been valued using market quotations. In addition, there is no assurance that the Fund could sell a portfolio investment at any time for the value ascribed to it for purposes of calculating the Fund’s net asset value, and it is possible that the Fund could incur a loss because an investment is sold at a discount to its ascribed value. The ability to value investments may also be impacted by technological issues and/or errors by pricing services or other third-party service providers.
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. There can be no guarantee that the Adviser's investment techniques or investment decisions will produce the desired results. 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 Small 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 measure of market performance and an
additional index 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, Class R, Class Y and Class I shares of the predecessor fund. Class A, Class C, Class R, Class Y and Class I shares of the predecessor fund were reorganized into Class A, Class C, Class R, Class Y and Class R6 shares, respectively, of the Fund after the close of business on May 24, 2019. Class A, Class C, Class R, Class Y and Class R6 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.
All Fund performance shown assumes the reinvestment of dividends and capital gains and the effect of the Fund’s expenses.
Updated performance information is available on the Fund’s website at www.invesco.com/us.

Performance shown on or prior to the inception date is that of the predecessor fund's Class A shares at net asset value and includes the 12b-1 fees applicable to that class. Although invested in the same portfolio of securities, Class R5 shares' returns of the Fund will be different from Class A shares' returns of the predecessor fund as they have different expenses.
After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor's tax situation and may differ from those shown, and after-tax returns shown are not relevant to investors who hold their Fund shares through tax-advantaged arrangements, such as 401(k) plans, 529 college savings plans or individual retirement accounts. After-tax returns are shown for Class A shares only and after-tax returns for other classes will vary.

Class R5 shares of the Fund are offered only to grandfathered investors. With respect to Class R5 and Class R6 shares, there is no minimum initial investment for Employer Sponsored Retirement and Benefit Plans investing through a retirement platform that administers at least $2.5 billion in retirement plan assets. All other Employer Sponsored Retirement and Benefit Plans must meet a minimum initial investment of at least $1 million in each Fund in which it invests.
For all other institutional investors purchasing Class R5 or Class R6 shares, the minimum initial investment in each share class is $1 million, unless such investment is made by (i) an investment company, as defined under the Investment Company Act of 1940, as amended (1940 Act), that is part of a family of investment companies which own in the aggregate at least $100 million in securities, or (ii) an account established with a 529 college savings plan managed by Invesco, in which case there is no minimum initial investment.
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.
