The tables below describe the fees and expenses that you may pay, directly and indirectly, to invest in the Fund. You may qualify for sales charge discounts if you and your immediate family invest, or agree to invest in the future, at least $50,000 in one or more USAA Mutual Funds or Victory Funds. More information about these and other discounts is available in Purchases on page of the Fund's Prospectus, in Appendix A – Variations in Sales Charge Reductions and Waivers Available Through Certain Intermediaries, and from your investment professional.

Expenses after Reimbursement

aThe management fee (which is equal to an annualized rate of 0.75% of the Fund's average daily net assets) may fluctuate (increase or decrease by up to +/- 0.06% of the average nets assets of the Fund) based on the Fund's performance relative to the Lipper Global Funds Index measured over a rolling 36-month period. See Fund Management section for a description of the performance adjustment.

bThe expense information in the table has been restated to reflect current fees.

cVictory Capital Management Inc. (the "Adviser") has contractually agreed to waive its management fee and/or reimburse expenses so that the total annual operating expenses (excluding acquired fund fees and expenses, interest, taxes, brokerage commissions, capitalized expenses, and other extraordinary

expenses) do not exceed an annual rate of 1.09% of the Fund Shares, 1.00% of the Institutional Shares, and 1.35% of the Class A shares (formerly, Adviser Shares), through at least September 30, 2021. The Adviser is permitted to recoup advisory fees waived and expenses reimbursed for up to three years after the fiscal year in which the waiver or reimbursement took place, subject to the lesser of any operating expense limits in effect at the time of: (a) the original waiver or expense reimbursement; or (b) the recoupment, after giving effect to the recoupment amount. The amount of any waivers or reimbursements and the amount of any recoupment is calculated without regard to the impact of any performance adjustment to the Fund's management fee. This agreement may only be terminated by the Fund's Board of Trustees.

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. The Example also assumes that your investment has a 5% return each year, the Fund's operating expenses remain the same, and the expense limitation agreement for each class of shares is not continued beyond its expiration date. The Example does not reflect sales charges (loads) on reinvested dividends and other distributions. If these sales charges (loads) were included, your costs would be higher. 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
Fund Shares	$111	$347	$	601	$1,329
Inst. Shares	$102	$350	$	618	$1,384
Class A	$705	$998	$1,313		$2,202

Portfolio Turnover

The Fund pays transaction costs, including 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 shares of the Fund are held in a taxable account. These costs, which are not reflected in the Annual Fund Operating Expenses or in the Example, affect the Fund's performance.

For the most recent fiscal year, the Fund's portfolio turnover rate was 103% of the average value of its whole portfolio.

PRINCIPAL INVESTMENT STRATEGY

The Fund's principal investment strategy is to invest its assets primarily in equity securities of both foreign (including emerging markets) and domestic issuers. Under normal circumstances, the Fund expects to invest at least 40% of its assets in foreign securities (unless market conditions are not deemed favorable by Fund management, in which case the Fund would invest at least 30% of its assets in foreign securities). The "equity securities" in which the Fund principally invests are common stocks, depositary receipts, preferred stocks, securities convertible into common stocks, and securities that carry the right to buy common stocks.

The Fund normally invests its assets in investments that are tied economically to a number of countries throughout the world. A significant portion of the Fund's assets are in the securities of issuers organized or located outside the United States, whose

2

primary listing exchange for securities is located outside the United States, or whose largest amount of revenues or profits are derived from countries outside the United States. Under normal market conditions, the Fund's investments will be diversified in at least three countries, one of which is the United States, and may include developed and emerging market countries. The Fund may invest a significant percentage of its assets in securities of issuers in a single country, a small number of countries, or a particular geographic region.

The Fund uses a combination of quantitative analysis as well as an active bottom-up investment approach to buying and selling investments. A quantitative process is used to systematically evaluate an issuer's valuation, price and earnings momentum, earnings quality, and other factors also may be considered. Investments are also selected based on fundamental analysis of individual issuers and their potential in light of their financial condition and market, economic, political, and regulatory conditions. Factors considered may include analysis of an issuer's earnings, cash flows, competitive position, and management ability.

While these terms are often used interchangeably in the investment industry, for purposes of the Fund, the portfolio managers primarily focus on integrating sustainable investing, responsible investing, or environmental, social, and governance ("ESG") analysis (collectively referred to as "sustainable investing"), which generally is understood to entail incorporating financially material ESG considerations into the investment process in order to seek better risk-adjusted returns. Such considerations can include, for example, environmental implications, such as a company's commitment to reducing carbon emissions, adoption of corporate cultural policies that promote employee inclusion and diversity, fair labor practices, measures to protect privacy and data security, and responsible supply chain management. The portfolio managers evaluate these non-financial factors alongside more traditional financial, macroeconomic, and other qualitative indicators in an effort to enhance performance, manage investment risks, and identify emerging investment risks or investment opportunities. In arriving at an investment decision, an investment team can take into account a variety of information from industry sources, independent research, company disclosures, and discussions with a company's management regarding the company's commitment and position, relative to other companies being evaluated, about sustainable investing issues and applies its experienced, qualitative judgment to this information and other available fundamental factors. Third-party ESG ratings can be considered as a consideration in an investment team's investment process; however, such ratings are only one factor considered as it relates to a company's sustainability initiatives and no rating is definitive in making an investment decision. Furthermore, a team may disagree with the analysis provided by third party research. Sustainable investing principles and considerations are not an exclusive factor, but rather an additional inclusive consideration to an investment team's process. The sustainable investing factors considered, the types of information used, and the integration of those factors and information into the investment process varies by investment team.

PRINCIPAL RISKS

The Fund's investments are subject to the following principal risks:

Stock Market Risk – Overall stock market risks may affect the value of the Fund. Domestic and international factors such as political events, war, trade disputes, interest rate levels and other fiscal and monetary policy changes, pandemics and other public health crises, and related geopolitical events, as well as environmental disasters such as earthquakes, fires, and floods, may add to instability in world economies and markets generally. The impact of these and other factors may be short- term or may last for extended periods.

Equity Risk – The value of the equity securities in which the Fund invests may decline in response to developments affecting individual companies and/or general economic conditions. A company's earnings or dividends may not increase as expected due to poor management decisions, competitive pressures, breakthroughs in technology, reliance on suppliers, labor problems or shortages, corporate restructurings, fraudulent disclosures, natural disasters, military confrontations, war, terrorism, public health crises, or other events, conditions, and factors. Price changes may be temporary or last for extended periods.

Foreign Securities Risk – Foreign markets can be more volatile than the U.S. market due to increased risks of adverse issuer, political, regulatory, market, or economic developments and can perform differently from the U.S. market.

Emerging Markets Risk – Foreign securities risk can be particularly heightened because investments in emerging market countries generally are more volatile than investments in developed markets. Emerging market countries are less economically diverse and mature than more developed countries and tend to be politically less stable.

Geographic Risk – The Fund's performance could be closely tied to the market, currency, economic, political, regulatory, geopolitical, or other conditions and developments in the countries or regions in which the Fund invests. As such, the Fund's performance could be more volatile than the performance of more geographically diversified funds.

Sustainable Investing Policy Risk – The portfolio managers' integration of responsible investing or ESG considerations may result in the Fund forgoing some market opportunities available to funds that do not apply such considerations. Responsible investing considerations may be linked to long-term rather than short-term returns. Third-party information and data used by a portfolio manager might be incorrect or only take into account one of many ESG-related components of portfolio companies.

Large Shareholders Risk – The actions by one shareholder or multiple shareholders may have an impact on the Fund and, therefore, indirectly on other shareholders. Shareholder purchase and redemption activity may affect the per share amount of the Fund's distributions of its net investment income and net realized capital gains, if any, thereby affecting the tax burden on the Fund's shareholders subject to federal income tax. To the extent a larger shareholder (including, for example, an Affiliated Fund that operates as a fund-of-funds or 529 college savings plan) is permitted to invest in the Fund, the Fund may experience large inflows or outflows of cash from time to time. This activity could magnify these adverse effects on the Fund.

Portfolio Turnover Risk – The frequent changes in the allocation of the Fund's portfolio holdings may result in higher portfolio turnover. When the Fund engages in active and frequent trading, the Fund will pay more brokerage

3

commissions than it would if it did not actively and frequently trade. In addition, the Fund may have a higher proportion of capital gains and a potentially lower return than a fund that does not actively and frequently trade.

Any investment involves risk, and there is no assurance that the Fund's objective will be achieved. By itself, the Fund does not constitute a complete investment plan. As you consider an investment in the Fund, you also should take into account your tolerance for the daily fluctuations of the financial markets and whether you can afford to leave your money in the Fund for long periods of time to ride out down periods. As with other mutual funds, losing money is a risk of investing in the Fund.

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 government agency.

PERFORMANCE

The following bar chart and table are intended to help you understand some of the risks of investing in the Fund. The Fund has three classes of shares: Fund Shares, Institutional Shares, and Class A shares. The bar chart illustrates the Fund Shares class' volatility by showing how performance has varied from year to year for each full calendar year over the past 10 years. The table shows how the average annual total returns of the share classes for the periods indicated compared to those of the Fund's benchmark index and an additional index of funds with similar investment objectives and is representative of the Fund's prior principal investment strategy. Performance reflects any expense limitations in effect during the periods shown.

Performance data for the classes varies based on differences in their fee and expense structures. Remember, historical performance (before and after taxes) does not necessarily indicate what will happen in the future. The Fund's most current performance information is available on the Fund's website at usaa.com (effective on or about November 6, 2020, performance information may be found at vcm.com) or by calling (800) 235-8396. Effective June 29, 2020, the Fund's Adviser Shares were redesignated Class A shares, subject to a front-end sales load and different fees and expenses. Performance of the Class A shares, therefore, is that of the Adviser Shares and has been restated to reflect the sales load

applicable to Class A shares but not any difference in the fees and expenses.

Highest Quarter Return	14.61%	March 31, 2019
Lowest Quarter Return	-18.02%	September 30, 2011

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. In certain situations, the return after taxes on distributions and sale of fund shares may be higher than the other return amounts. A higher after-tax return may result when a capital loss occurs upon redemption and translates into an assumed tax deduction that benefits the shareholder. The actual after-tax returns depend on your tax situation and may differ from those shown. If you hold your shares through a tax-deferred arrangement, such as an individual retirement account ("IRA") or 401(k) plan, the after- tax returns shown in the table are not relevant to you. Please note that after-tax returns are shown only for the Fund Shares and may differ for each share class.

You may purchase or sell Fund Shares any business day through the vcm.com website or by telephone at (800) 235- 8396. You also may purchase or sell Fund Shares through certain other financial intermediaries. If you have opened an account directly with the Fund, you also may purchase and sell Fund Shares by mail at P.O. Box 182593, Columbus, OH 43210-2593.

Institutional Shares are not offered for sale directly to the general public. The Fund reserves the right to waive or lower purchase minimums in certain circumstances.

For Class A shares a $1,000 minimum initial purchase amount and a $50 minimum subsequent purchase amount apply for Individual Retirement Accounts ("IRAs"), gift/transfer to minor accounts, and purchases through automatic investment plans.

Certain broker-dealers and other financial intermediaries (such as a bank) may establish higher or lower minimum initial and subsequent investment amounts to which you may be subject if you invest through them.

When you buy and redeem shares, the Fund will price your transaction at the next-determined net asset value ("NAV") after the Fund receives your request in good order, which means that your request contains all the required documentation, and that all documents contain required signatures or signature guarantees from a financial institution.

TAX INFORMATION

The Fund intends to make distributions that generally will be taxed to you as ordinary income or long-term capital gains, unless you are a tax-exempt investor or you invest through an IRA, 401(k) plan, or other tax-deferred account (in which case you may be taxed later, upon withdrawal of your investment from such account).

PAYMENTS TO BROKER- DEALERS AND OTHER FINANCIAL INTERMEDIARIES

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund and its related companies may pay the intermediary for the sale of such shares and certain servicing and administrative functions. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your financial adviser to recommend the Fund over another investment. Ask your financial adviser or visit your financial intermediary's website for more information.
