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.

The Fund’s investment adviser, The Variable Annuity Life Insurance Company (“VALIC”), has contractually agreed to waive its advisory fee until September 30, 2022, so that the advisory fee payable by the Fund to VALIC equals 0.53% on the first $500 million of the Fund’s average daily net assets and 0.505% on average daily net assets over $500 million. This agreement may be modified or discontinued prior to such time only with the approval of the Board of Directors of VALIC Company I (“VC I”), including a majority of the directors who are not “interested persons” of VC I as defined in the Investment Company Act of 1940, as amended.

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 fee waivers 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
$69		$265		$477		$1,088

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.

During the most recent fiscal year, the Fund’s portfolio turnover rate was 20% of the average value of its portfolio.

Principal Investment Strategies of the Fund

The Fund seeks to achieve a higher risk-adjusted performance than the Russell 1000^® Index (the “Index”)

- 1 -

over the long term through a proprietary selection process employed by the Fund’s Subadviser. The Fund primarily invests in common stock of U.S. large capitalization companies included in the Index. As of June 30, 2021, the median market capitalization of a company in the Index was approximately $15.2 billion and the dollar-weighted average capitalization of the companies in the Index was approximately $481.6 billion. The size of the companies in the Index changes with market conditions and the composition of the Index.

The Subadviser uses a rules-based methodology that emphasizes quantitatively-based stock selection and portfolio construction and efficient implementation. The Fund seeks to capture common sources of active equity returns, including the following factors: value (i.e., how attractively a stock is priced relative to its “fundamentals,” such as book value and free cash flow), momentum (i.e., whether a company’s share price is trending up or down), quality (i.e., profitability) and low volatility (i.e., a relatively low degree of fluctuation in a company’s share price over time). The Subadviser seeks to capitalize on the low correlations in returns across these factors by diversifying exposure to securities selected based on such factors. The Subadviser may, in its discretion, make changes to its quantitative techniques, or use other quantitative techniques that are based on the Subadviser’s proprietary research.

The Subadviser constructs the Fund’s portfolio by investing in the securities comprising the Index and adjusting the relative weight of each security based on the security’s attractiveness when evaluated based on the factors as described above, subject to the Fund being constrained to long-only positions. Based on the Subadviser’s process, the Fund expects that its portfolio will be overweight with respect to certain securities (i.e., the Fund will hold a greater percentage of those securities than the Index) and underweight with respect to others (i.e., the Fund will hold a lesser percentage of those securities than the Index), and that such weightings may change over time. The percentage of the Fund’s portfolio exposed to any single security will vary from time to time as the weightings of the securities within the Fund change. The degree to which components of the Fund represent certain sectors or industries may change over time.

The Subadviser will rebalance the Fund’s portfolio according to the process set forth above on a quarterly basis, and it generally employs a strategy to continue to hold securities between quarterly rebalancings, even if there are adverse developments concerning a particular security, an industry, the economy or the stock market generally. The Subadviser may reduce the position size of

a security or sell the security during quarterly rebalancings if the security no longer has favorable scores in one or more of the four factors.

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.

Disciplined Strategy Risk. The Fund will generally not deviate from its strategy, even during adverse market, economic, political, or other conditions (except to the extent necessary to comply with federal tax laws or other applicable laws). If the Fund is committed to a strategy that is unsuccessful, the Fund will not meet its investment goal. Because the Fund generally will not use certain techniques available to other mutual funds to reduce stock market exposure, the Fund may be more susceptible to general market declines than other mutual funds.

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.

Factor-Based Investing Risk. There can be no assurance that the multi-factor selection process employed by the subadviser will enhance performance. Exposure to investment style factors may detract from performance in some market environments, which may continue for prolonged periods.

- 2 -

Large-Cap Companies Risk. Large-cap companies tend to go in and out of favor based on market and economic conditions and tend to be less volatile than companies with smaller market capitalizations. In exchange for this potentially lower risk, the Fund’s value may not rise as much as the value of funds that emphasize smaller capitalization companies. Larger, more established companies may be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes. Larger companies also may not be able to attain the high growth rate of successful smaller companies, particularly during extended periods of economic expansion.

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

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

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.
