Investment Objective

The Fund seeks capital growth by investing in common stocks. Income is a secondary objective.

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.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Management Fees	0.72%
Other Expenses	0.11%
Total Annual Fund Operating Expenses	0.83%
Fee Waivers and/or Expense Reimbursements1	0.16%
Total Annual Fund Operating Expenses After Fee Waivers and/or Expense Reimbursements1	0.67%

The Fund’s investment adviser, The Variable Annuity Life Insurance Company (“VALIC”), has contractually agreed to waive its advisory fee until September 30, 2027, so that the advisory fee payable by the Fund to VALIC equals 0.59% on the first $250 million of the Fund’s average daily net assets, 0.56% on the next $250 million of the Fund’s average daily net assets, 0.51% on the next $500 million of the Fund’s average daily net assets and 0.46% on average daily net assets over $1 billion. 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.

Expense 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 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 remain the same (except that the Example incorporates any applicable fee waiver and/or expense limitation arrangements for only the first year). The Example does not reflect charges imposed by the Variable Contract. If the separate account 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
$68	$249	$445	$1,011

Portfolio Turnover

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 95% of the average value of its portfolio.

Principal Investment Strategies of the Fund

Under normal circumstances, the Fund will invest at least 80% of its net assets in dividend paying securities of value companies.For purposes of the Fund’s 80% investment policy, a company is considered to be a value company if it: (i) issues securities that are presented in a third-party value-style index or that are classified as a value company by a third-party vendor; or (ii) meets a relevant equity market measurement in at least one “value metric” similar to those commonly used by third-party index providers or third-party vendors in value classifications, such as earnings growth, price-to-earnings or sales growth, among others.

The Fund seeks to achieve its objective by investing primarily in a diversified portfolio of equity securities including common stock, preferred stock and convertible securities. The Fund may invest in securities of companies with any market capitalization, but will generally focus on large cap securities. The Fund may invest up to 25% of its net assets in equity securities of foreign issuers, either directly or through depositary receipts. The foreign issuers in which the Fund may invest include issuers that are organized outside the United States and conduct their operations in the United States and other countries and other foreign issuers with market capitalizations generally of at least $10 billion.

In selecting portfolio securities, one of the Subadvisers will generally employ a value-oriented analysis, but may purchase equity securities based on a growth-oriented analysis when such securities pay dividends or the Subadviser believes such securities have particularly good prospects for capital appreciation. The other Subadviser typically emphasizes dividend paying equity securities with a focus placed upon current dividend levels as well as dividend growth over time and looks for potential for capital appreciation, sound or improving balance sheets and effective management teams that exhibit a desire to earn consistent returns for shareholders.

The Fund may also invest in non convertible preferred stock, securities of other investment companies and of real estate investment trusts (“REITs”), warrants and rights.

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 a subadviser 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.

Dividend-paying Stocks Risk. The Fund’s emphasis on dividend-paying stocks could cause the Fund to underperform similar funds that invest without consideration of a company’s track record of paying dividends. There is no guarantee that the issuers of the stocks held by the Fund will declare dividends in the future or that, if dividends are declared, they will remain at their current levels or increase over time. Dividend-paying stocks may not participate in a broad market advance to the same degree as other stocks, and a sharp rise in interest rates or economic downturn could cause a company to unexpectedly reduce or eliminate its dividend.

Equity Securities Risk. The Fund invests principally in equity securities and is therefore 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.

Value Style Risk. Generally, “value” stocks are stocks of companies that are considered to be currently undervalued in the marketplace. The assessment that a particular security is undervalued in relation to the company’s fundamental economic value may prove incorrect, and the price of the company’s stock may fall or may not approach the value that has been attributed to it.

Growth Style Risk. Generally, “growth” stocks are stocks of companies that 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.

Convertible Securities Risk. Convertible security values may be affected by market interest rates, issuer defaults and underlying common stock values; security values may fall if market interest rates rise and rise if market interest rates fall. Additionally, an issuer may have the right to buy back the securities at a time unfavorable to the Fund.

Preferred Stock Risk. Unlike common stock, preferred stock generally pays a fixed dividend from a company’s earnings and may have a preference over common stock on the distribution of a company’s assets in the event of bankruptcy or liquidation. Preferred stockholders’ liquidation rights are subordinate to the company’s debt holders and creditors. If interest rates rise, the fixed dividend on preferred stocks may be less attractive and the price of preferred stocks may decline. Preferred stockholders typically do not have voting rights.

Income Producing Stock Availability Risk. Income producing common stock meeting the Fund’s investment criteria may not be widely available and/or may be highly concentrated in only a few market sectors, thus limiting the ability of the Fund to produce current income while remaining fully diversified.

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. 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.

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 social, political or economic developments here or abroad, changes in

investor psychology, technological disruptions, or heavy institutional selling and other conditions or events (including, for example, military confrontations, war, terrorism, trade wars, 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.

Mid-Cap Company Risk. Investing in mid-cap companies carries the risk that due to current market conditions these companies may be out of favor with investors. Stocks of mid-cap companies may be more volatile than those of larger companies due to, among other reasons, narrower product lines, more limited financial resources and fewer experienced managers.

Small-Cap Company Risk. Investing in small-cap companies carries the risk that due to current market conditions these companies may be out of favor with investors. Small companies often are in the early stages of development with limited product lines, markets, or financial resources and managements lacking depth and experience, which may cause their stock prices to be more volatile than those of larger companies. Small company stocks may be less liquid yet subject to abrupt or erratic price movements. It may take a substantial period of time before the Fund realizes a gain on an investment in a small-cap company, if it realizes any gain at all.

Foreign Investment Risk. Investment in foreign securities involves risks due to several factors, such as illiquidity, the lack of public information, changes in the exchange rates between foreign currencies and the U.S. dollar, unfavorable political, social and legal developments, or economic and financial instability. Foreign companies are not subject to the U.S. accounting and financial reporting standards and may have riskier settlement procedures. U.S. investments that are denominated in foreign currencies or that are traded in foreign markets, or securities of U.S. companies that have significant foreign operations may be subject to foreign investment risk.

Depositary Receipts Risk.Depositary receipts are generally subject to the same risks as the foreign securities that they evidence or into which they may be converted. Depositary receipts may or may not be jointly sponsored by the underlying issuer. The issuers of unsponsored depositary receipts are not obligated to disclose information that is considered material in the United States. Therefore, there may be less information available regarding the issuers and there may not be a correlation between such information and the market value of the depositary receipts. Certain depositary

receipts are not listed on an exchange and therefore may be considered to be illiquid securities.

Warrants and Rights Risk. Warrants and rights can provide a greater potential for profit or loss than an equivalent investment in the underlying security. Warrants and rights have no voting rights, pay no dividends and have no rights with respect to the assets of the issuer other than a purchase option. Prices of warrants and rights do not necessarily move in tandem with the prices of the underlying securities and therefore are highly volatile and speculative investments. Warrants and rights may lack a liquid secondary market for resale. If a warrant or right held by the Fund is not exercised by the date of its expiration, the Fund would lose the entire purchase price of the warrant or right.

Real Estate Investment Trusts Risk. REITs are trusts that invest primarily in commercial real estate, residential real estate or real estate related loans. The value of an interest in a REIT may be affected by the value and the cash flows of the properties owned or the quality of the mortgages held by the REIT. The performance of a REIT depends on current economic conditions and the types of real property in which it invests and how well the property is managed. If a REIT concentrates its investments in a geographic region or property type, changes in underlying real estate values may have an exaggerated effect on the value of the REIT.

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 below bar chart and table illustrate the risks of investing in the Fund by showing changes in the Fund’s performance from calendar year to calendar year and comparing the Fund’s average annual returns to those of the S&P 500® Index (a broad-based securities market index) and the Russell 1000® Value Index, which is relevant to the Fund because it has characteristics similar to the Fund’s investment strategies. Fees and expenses incurred at the contract level are not reflected in the bar chart or table. If these amounts were reflected, returns would be less than those shown. Of course, past performance of the 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.
