Victory Mid-Cap Core Growth Fund Summary

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 shown and then sell or continue to 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. The amounts shown reflect any fee waiver/expense reimbursement in place through its expiration date. After eight years, Class C shares of the Fund generally will convert automatically to Class A shares of the Fund. The example for Class C shares reflects the conversion to Class A shares after eight years. 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
Class A	$696	$952	$1,227	$2,010
Class C	$315	$950	$1,707	$3,183
Class R6	$89	$278	$482	$1,073
Class Y	$101	$315	$547	$1,213

The following example makes the same assumptions as the example above, except that it assumes you do not sell your Class C shares at the end of the period. 

	1 Year	3 Years	5 Years	10 Years
Class C	$215	$950	$1,707	$3,183

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.

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. For the most recent fiscal year, the Fund's portfolio turnover rate was 100% of the average value of its portfolio.

Principal Investment Strategy

Under normal circumstances, the Fund invests at least 80% of its net assets (plus the amount of borrowings, if any, for investment purposes) in equity securities of mid-capitalization companies.

Mid-capitalization companies are those companies with market capitalizations within the range of companies included in the S&P MidCap 400® Index ($1.8 billion to $44.9 billion as of September 30, 2026) or within the range of companies included in the Russell Midcap® Index ($1.8 billion to $123.3 billion as of September 30, 2026). The size of companies in an index changes with market conditions and the composition of the index.

The Adviser employs a quantitative investment process that identifies equity securities of companies across mid-cap companies. The Adviser uses a disciplined approach that combines value, momentum, quality, and growth factors to construct a diversified portfolio.

The Adviser's quantitative methodology looks at investment fundamentals to evaluate potential investments from a broad universe of securities. The quantitative analysis focuses on, among other things:

The Adviser's quantitative approach is designed to diversify the Fund's holdings and optimize risk-adjusted returns. The Adviser attempts to manage portfolio risks by limiting exposure to particular industry sectors and stocks of individual issuers.

The Fund generally will sell portfolio holdings when quantitative factors signal that a stock's value is likely to deteriorate materially, when more attractive opportunities are identified, or to manage risks within identified parameters.

Although the Fund will be invested primarily in domestic securities, up to 10% of the Fund's assets may be invested in foreign securities, including depositary receipts such as American Depositary Receipts ("ADRs") and Global Depositary Receipts ("GDRs").

Principal Risks

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

Equity Securities 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 in the United States or abroad. A company's earnings or dividends may not increase as expected (or may decline) because of poor management, competitive pressures, reliance on particular suppliers or geographical regions, labor problems or shortages, corporate restructurings, fraudulent disclosures, man-made or natural disasters, military confrontations or wars, terrorism, public health crises, or other events, conditions, and factors. Price changes may be temporary or last for extended periods. Equity securities have the lowest priority, and the greatest risk, with respect to dividends and any liquidation payments in the event of an issuer's bankruptcy.

General Market Risk - Overall market risks may affect the value of the Fund. Domestic and international factors such as political events, war, terrorism, trade disputes, inflation rates, interest rate levels, and other fiscal and monetary policy changes; cybersecurity incidents, pandemics, and other public health crises; imposition of tariffs; sanctions against a particular foreign country, its nationals, businesses, or industries; and related geopolitical events, as well as environmental disasters such as earthquakes, fires, and floods, or other catastrophes, may add to instability in global economies and markets generally, and may lead to increased market volatility. Global economies and financial markets are highly interconnected, which increases the possibility that conditions in one

Victory Mid-Cap Core Growth Fund Summary

country or region might adversely affect issuers in another country or region. The impact of these and other factors may be short-term or may last for extended periods.

Mid-Capitalization Stock Risk - Mid-sized companies may be subject to a number of risks not associated with larger, more established companies, potentially making their stock prices more volatile and increasing the risk of loss.

Foreign Securities Risk - Foreign securities (including depositary receipts) are subject to political, regulatory, and economic risks not present in domestic investments. Foreign securities could be affected by factors not present in the United States, including expropriation, confiscation of property, and difficulties in enforcing contracts. Compared to U.S. companies, there generally is less publicly available information about foreign companies and there may be less governmental regulation and supervision of foreign companies. Foreign securities generally experience more volatility than their domestic counterparts. Depositary receipts may have additional risks, including creditworthiness of the depositary bank and the risk of an illiquid market. In addition, to the extent investments are made in a limited number of countries, events in those countries will have a more significant impact on the Fund. Fluctuations in the exchange rates between the U.S. dollar and foreign currencies, currency exchange control regulations, and restrictions or prohibitions on the repatriation of foreign currencies may negatively affect an investment. Dividends and interest received by the Fund and capital gains recognized by the Fund may give rise to withholding and other taxes imposed by foreign countries and may decrease the Fund's return.

Sector Focus Risk - To the extent the Fund focuses on one or more sectors, such as the financials sector, market or economic factors impacting those sectors could have a significant effect on the value of the Fund's investments and could make the Fund's performance more volatile.

Investment Style Risk - Different types of investment styles, for example growth or value, tend to perform differently and shift into and out of favor with investors depending on changes in market and economic sentiment and conditions. As a result, the Fund's performance may at times be worse than the performance of other mutual funds that invest more broadly or that have different investment styles.

Liquidity Risk - Lack of a ready market or restrictions on resale may limit the ability of the Fund to dispose of certain holdings quickly or at prices that represent true market value in the judgment of the Adviser. In addition, the Fund, by itself or together with other accounts managed by the Adviser, may hold a position in an investment that is large relative to the typical trading volume for that investment, which can make it difficult for the Fund to dispose of the position at an advantageous time or price. Illiquid investments and relatively less-liquid investments may also be difficult to value. Liquidity risk may also refer to the risk that the Fund may not be able to pay redemption proceeds within the allowable time period because of unusual market conditions, unusually high volume of redemptions, or other reasons. To meet redemption requests or to raise cash to pursue other investment opportunities, the Fund may be forced to sell investments at an unfavorable time and/or under unfavorable conditions, which may adversely affect the Fund.

Large Shareholder Risk - Certain large shareholders, including other funds advised by the Adviser, may from time to time own a substantial amount of the Fund's shares. The actions by one shareholder

Victory Mid-Cap Core Growth Fund Summary

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, and/or accelerate the realization of taxable income and cause the Fund to make taxable distributions to its shareholders earlier than the Fund otherwise would have. In addition, under certain circumstances, non-redeeming shareholders may be treated as receiving a disproportionately large taxable distribution during or with respect to such tax year. To the extent a larger shareholder 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.

Management Risk - The portfolio managers may not execute the Fund's principal investment strategy effectively.

You may lose money by investing in the Fund. There is no guarantee that the Fund will achieve its objective. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

By itself, the Fund does not constitute a complete investment plan and should be considered a long-term investment for investors who can afford to weather changes in the value of their investment.

Investment Performance

The bar chart and table that follow are intended to help you understand some of the risks of investing in the Fund. The bar chart shows you how the Fund's calendar year performance has varied over the past 10 years. The table compares the Fund's average annual total returns of the Fund's share classes, including applicable maximum sales charges, over the same period to one or more broad measures of market performance. The S&P 500® Index serves as the Fund's regulatory broad-based securities market index. We assume reinvestment of dividends and distributions.

Performance data for the classes varies based on differences in their fee and expense structures and reflects any expense limitations in effect during the periods shown. The Fund's investment team changed on November 1, 2025. The Fund's past performance (before and after taxes) does not necessarily indicate how the Fund will perform in the future. Updated performance information is available on the Fund's website at vcm.com.

After-tax returns use the historical highest individual federal marginal income tax rates and do not reflect the effect 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 (including before taxes). 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. Actual after-tax returns depend on your tax situation and may differ from those shown. After-tax returns shown are not relevant if you own your Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts. After-tax returns are shown for only one share class. The after-tax returns for other classes will vary.

Purchase and Sale of Fund Shares 

Investment Minimums	Class A	Class C	Class R6	Class Y
Minimum Initial Investment	$2,500	$2,500	None	$1,000,000
Minimum Subsequent Investments	$50	$50	None	None

For Class A and Class C 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.

You may redeem your shares on any day the Fund is open for business. Redemption requests may be made by telephone (with prior appropriate approval) or by mail.

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's distributions may be taxable whether you receive them in cash, additional shares of the Fund, or you reinvest them in shares of another Victory Fund, and may be taxed as ordinary income or capital gains, unless you are investing through a tax-deferred arrangement, such as a 401(k) plan or an individual retirement account. Taxes may be imposed on withdrawals from tax-deferred arrangements.

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 and 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 financial intermediary and its financial advisor to recommend the Fund over another investment. Ask your financial advisor or visit your financial intermediary's website for more information.
