The Fund seeks long-term capital appreciation by investing primarily in a broadly diversified portfolio of stocks and other equity securities of U.S. companies.

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 the example below do not reflect the separate account fees charged in the variable annuity or variable life insurance policy (“Variable Contracts”) in which the Fund is offered. If separate account fees were shown, the Fund’s annual operating expenses would be higher. Please see your Variable Contract prospectus for more details on the separate account fees.

Management Fees	0.55%
Other Expenses	0.20%
Total Annual Fund Operating Expenses	0.75%
Fee Waivers and/or Expense Reimbursements1	0.15%
Total Annual Fund Operating Expenses After Fee Waivers and/or Expense Reimbursements1	0.60%

Pursuant to an Expense Limitation Agreement, The Variable Annuity Life Insurance Company (“VALIC”) has contractually agreed to reimburse the expenses of the Fund until September 30, 2022, so that the Fund’s Total Annual Fund Operating Expenses After Fee Waivers and/or Expense Reimbursements do not exceed 0.60%. For purposes of the Expense Limitation Agreement, “Total Annual Fund Operating Expenses” shall not include extraordinary expenses (i.e., expenses that are unusual in nature and infrequent in occurrence, such as litigation), or acquired fund fees and expenses, brokerage commissions and other transactional expenses relating to the purchase and sale of portfolio securities, interest, taxes and

governmental fees, and other expenses not incurred in the ordinary course of the Fund’s business. This agreement will be renewed annually for one-year terms unless terminated by the Board of Directors of VALIC Company I prior to any such renewal.

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 or hold all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses include expense reimbursements for year one. The Example does not reflect charges imposed by the Variable Contract. If the Variable Contract fees were reflected, the expenses would be higher. See the Variable Contract prospectus for information on such charges. Although your actual costs may be higher or lower, based on these assumptions and the net expenses shown in the fee table, your costs would be:

1 Year		3 Years		5 Years		10 Years
$61		$225		$402		$916

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance.

As a result of a reorganization which occurred on May 24, 2021 (the “Reorganization”), the Fund acquired all of the assets and liabilities of the Capital Appreciation Fund (the “Predecessor Fund”), a series of VALIC Company II. During the fiscal year ended August 31, 2020, the portfolio

turnover rate of the Predecessor Fund was 62% of the average value of its portfolio. During the fiscal period September 1, 2020 to May 31, 2021, the portfolio turnover rate of the Predecessor Fund and the Fund was 27% (not annualized) of the average value of the portfolio.

Principal Investment Strategies of the Fund

The Fund invests in equity securities of large-sized U.S. companies similar in size, at the time of purchase, to those within the Russell 1000^® Growth Index. As of May 7, 2021, the largest stock by market capitalization in the Russell 1000^® Growth Index was approximately $2.2 trillion and the median was $17.8 billion. The subadviser selects stocks using a unique, growth-oriented approach, focusing on high quality companies with sustainable earnings growth that are available at reasonable prices, which combines the use of proprietary analytical tools and the qualitative judgments of the investment team. In general, the subadviser believes companies that are undervalued relative to their fundamentals and exhibit improving investor interest outperform the market over full market cycles. As a result, the subadviser’s investment process begins by using tools to rank stocks based on expected returns, construct preliminary portfolios with the use of fundamental factors, and manage risk. All purchases and sales of portfolio securities, however, are subjected ultimately to the investment team’s qualitative judgments developed from their cumulative investment experience. The entire process is designed to focus on company fundamentals through both quantitative and qualitative analysis to balance return generation with risk management. Although the Fund typically invests in common stocks of domestic companies, the Fund may occasionally invest in the equity securities of foreign issuers (up to a maximum of 20% of total assets).

In order to generate additional income, the Fund may lend portfolio securities to broker-dealers and other financial institutions provided that the value of the loaned securities does not exceed 30% of the Fund’s total assets. These loans earn income for the Fund and are collateralized by cash and securities issued or guaranteed by the U.S. Government or its agencies or instrumentalities.

Principal Risks of Investing in the Fund

As with any mutual fund, there can be no assurance that the Fund’s investment objective will be met or that the net return on an investment in the Fund will exceed what could have been obtained through other investment or savings vehicles. Shares of the Fund are not bank deposits and are not guaranteed or insured by any bank, government entity or the Federal Deposit Insurance Corporation. If the

value of the assets of the Fund goes down, you could lose money.

The following is a summary of the principal risks of investing in the Fund.

Management Risk. The investment style or strategy used by the Fund may fail to produce the intended result. A subadviser’s assessment of a particular security or company may prove incorrect, resulting in losses or underperformance.

Equity Securities Risk. The Fund’s investments in equity securities are subject to the risk that stock prices will fall and may underperform other asset classes. Individual stock prices fluctuate from day-to-day and may decline significantly. The prices of individual stocks may be negatively affected by poor company results or other factors affecting individual prices, as well as industry and/or economic trends and developments affecting industries or the securities market as a whole.

Growth Style Risk. Generally, “growth” stocks are stocks of companies that a subadviser believes have anticipated earnings ranging from steady to accelerated growth. Many investors buy growth stocks because of anticipated superior earnings growth, but earnings disappointments often result in sharp price declines. Growth companies usually invest a high portion of earnings in their own businesses so their stocks may lack the dividends that can cushion share prices in a down market. In addition, the value of growth stocks may be more sensitive to changes in current or expected earnings than the value of other stocks, because growth stocks trade at higher prices relative to current earnings.

Large-Cap Companies Risk. Investing primarily in large-cap companies carries the risk that due to current market conditions these companies may be out of favor with investors. Large-cap companies may be unable to respond quickly to new competitive challenges or attain the high growth rate of successful smaller companies.

Market Risk. The Fund’s share price can fall because of weakness in the broad market, a particular industry, or specific holdings or due to adverse political or economic developments here or abroad, changes in investor psychology, or heavy institutional selling and other conditions or events (including, for example, military confrontations, war, terrorism, disease/virus, outbreaks and epidemics). The prices of individual securities may fluctuate, sometimes dramatically, from day to day. The prices of stocks and other equity securities tend to be more volatile than those of fixed-income securities.

The coronavirus pandemic and the related governmental and public responses have had and may continue to have an impact on the Fund’s investments and net asset value and have led and may continue to lead to increased market volatility and the potential for illiquidity in certain classes of securities and sectors of the market. Preventative or protective actions that governments may take in respect of pandemic or epidemic diseases may result in periods of business disruption, business closures, inability to obtain raw materials, supplies and component parts, and reduced or disrupted operations for the issuers in which the Fund invests. Government intervention in markets may impact interest rates, market volatility and security pricing. The occurrence, reoccurrence and pendency of such diseases could adversely affect the economies (including through changes in business activity and increased unemployment) and financial markets either in specific countries or worldwide.

Securities Lending Risk. Engaging in securities lending could increase the market and credit risk for Fund investments. The Fund may lose money if it does not recover borrowed securities, the value of the collateral falls, or the value of investments made with cash collateral declines. The Fund’s loans will be collateralized by securities issued or guaranteed by the U.S. Government or its agencies and instrumentalities, which subjects the Fund to the credit risk of the U.S. Government or the issuing federal agency or instrumentality. If the value of either the cash collateral or the Fund’s investments of the cash collateral falls below the amount owed to a borrower, the Fund also may incur losses that exceed the amount it earned on lending the security. Securities lending also involves the risks of delay in receiving additional collateral or possible loss of rights in the collateral if the borrower fails. Another risk of securities lending is the risk that the loaned portfolio securities may not be available to the Fund on a timely basis and the Fund may therefore lose the opportunity to sell the securities at a desirable price.

Performance Information

The returns presented for the Fund reflect the performance of the Predecessor Fund. The Fund adopted the performance of the Predecessor Fund as a result of the Reorganization on May 24, 2021. The Fund had not yet commenced operations prior to the Reorganization. The performance information below is based on the performance of the Predecessor Fund for periods prior to

the date of the Reorganization. The Fund and the Predecessor Fund had the same investment objectives, strategies and portfolio management team as of the date of the Reorganization.

If these amounts were reflected, returns would be less than those shown. Of course, past performance of the Predecessor Fund is not necessarily an indication of how the Fund will perform in the future.

Purchases and Sales of Fund Shares

Shares of the Funds may only be purchased or redeemed through Variable Contracts offered by the separate accounts of VALIC or other participating life insurance companies and through qualifying retirement plans (“Plans”) and IRAs. Shares of each Fund may be

purchased and redeemed each day the New York Stock Exchange is open, at the Fund’s net asset value determined after receipt of a request in good order.

The Funds do not have any initial or subsequent investment minimums. However, your insurance company may impose investment or account value minimums. The prospectus (or other offering document) for your Variable Contract contains additional information about purchases and redemptions of the Funds’ shares.

Tax Information

A Fund will not be subject to U.S. federal income tax so long as it qualifies as a regulated investment company and distributes its income and gains each year to its shareholders. However, contractholders may be subject to federal income tax (and a federal Medicare tax of 3.8% that applies to net income, including taxable annuity payments, if applicable) upon withdrawal from a Variable Contract. Contractholders should consult the prospectus (or other offering document) for the Variable Contract for additional information regarding taxation.

Payments to Broker-Dealers and
Other Financial Intermediaries

The Funds are not sold directly to the general public but instead are offered to registered and unregistered separate accounts of VALIC and its affiliates and to Plans and IRAs. The Funds and their related companies may make payments to the sponsoring insurance company or its affiliates for recordkeeping and distribution. These payments may create a conflict of interest as they may be a factor that the insurance company considers in including the Funds as underlying investment options in a variable contract. Visit your sponsoring insurance company’s website for more information.
