You may qualify for sales charge discounts in Class A Shares if you and your family invest, or agree to invest in the future, at least $50,000 in Virtus Funds.More information on these and other discounts is available: (i) from your financial professional or other financial intermediary; (ii) under “Sales Charges” on page 84 of the fund’s prospectus; and (iii) with respect to purchase of shares through specific intermediaries, in Appendix A to the fund’s prospectus, entitled “Intermediary Sales Charge Discounts and Waivers.”

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 or continued to hold them. The example also assumes that your investment has a 5% return each year and that the fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Class	Share Status	1 Year	3 Years	5 Years	10 Years
Class A	Sold or Held	$670	$925	$1,199	$1,978
Class C	Sold	$304	$630	$1,083	$2,338
	Held	$204	$630	$1,083	$2,338
Class I	Sold or Held	$101	$315	$547	$1,213
Class R6	Sold or Held	$92	$287	$498	$1,108

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. During the most recent fiscal year, the fund’s portfolio turnover rate was 7% of the average value of its portfolio.

Investments, Risks and Performance

Principal Investment Strategies

The fund pursues long-term capital appreciation in the small and medium market capitalization sectors while seeking to incur less risk than the small- and mid-cap markets. The fund invests in a select group of small and mid-market capitalization companies believed by the subadviser to be undervalued relative to their future growth potential. The investment strategy emphasizes companies the subadviser believes to have a sustainable competitive advantage, strong management and low financial risk and to be able to grow over market cycles. Although the fund invests primarily in U.S. companies, it may invest in foreign securities and depositary receipts.

Under normal circumstances, the fund invests at least 80% of its assets in common stocks of small and medium market capitalization companies. As of the date of this Prospectus, the fund’s subadviser considers small and medium market capitalization companies for this purpose to be those companies that, at the time of initial purchase, have market capitalizations within the range of companies included in the Russell 2500^TM Index on a rolling three-year basis. On this basis, as of September 30, 2024, the total market capitalization range of companies included in the Russell 2500^TM Index over the past three years was $43,500 to $56.5 billion. Generally, the fund invests in approximately 25 to 35 securities at any given time.

Principal Risks

The fund may not achieve its objective(s), and it is not intended to be a complete investment program. The value of the fund’s investments that supports your share value may decrease. If between the time you purchase shares and the time you sell shares the value of the fund’s investments decreases, you will lose money. Investment values can decrease for a number of reasons. Conditions affecting the overall economy, specific industries or companies in which the fund invests can be worse than expected, and investments may fail to perform as the subadviser expects. As a result, the value of your shares may decrease. Purchase and redemption activities by fund shareholders may impact the management of the fund and its ability to achieve its investment objective(s). The principal risks of investing in the fund are identified below.

>Equity Securities Risk:The value of the stocks held by the fund may be negatively affected by the financial market, industries in which the fund invests, or issuer-specific events. Focus on a particular style or in small or medium-sized companies may enhance that risk.

>Sector Focused Investing Risk: Events negatively affecting a particular market sector in which the fund focuses its investments may cause the value of the fund’s shares to decrease, perhaps significantly.

>Focused Investment Risk (Technology-Related Risk): To the extent the fund focuses its investments on a limited number of issuers, sectors, industries or geographic regions, it may be subject to increased risk and volatility. Risks affecting companies in the technology sector include competition from new and existing companies, limited operating histories and management experience, patent and other intellectual property considerations and the commercial non-viability or rapid obsolescence of equipment, products or services.

>Limited Number of Investments Risk: Because the fund may have a limited number of securities, it may be more susceptible to factors adversely affecting its securities than a fund with a greater number of securities.

>Market Volatility Risk: The value of the securities in the fund may go up or down in response to the prospects of individual companies and/or general economic conditions. Price changes may be short- or long-term. Local, regional or global events such as war or military conflict (e.g., Russia’s invasion of Ukraine), acts of terrorism, the spread of infectious illness or other public health issue, recessions, or other events could have a significant impact on the fund and its investments, including hampering the ability of the fund’s portfolio manager(s) to invest the fund’s assets as intended.

>Depositary Receipts Risk: Investments in foreign companies through depositary receipts may expose the fund to the same risks as direct investments in securities of foreign issuers.

>Foreign Investing Risk: Investing in foreign securities subjects the fund to additional risks such as increased volatility; currency fluctuations; less liquidity; less publicly available information about the foreign investment; and political, regulatory, economic, and market risk.

>Currency Rate Risk: Fluctuations in the exchange rates between the U.S. dollar and foreign currencies may negatively affect the value of the fund’s shares.

>Redemption Risk: One or more large shareholders or groups of shareholders may redeem their holdings in the fund, resulting in an adverse impact on remaining shareholders in the fund by causing the fund to take actions it would not otherwise have taken.

>Small and Medium Market Capitalization Companies Risk: The fund’s investments in small and medium market capitalization companies may increase the volatility and risk of loss to the fund, as compared with investments in larger, more established companies.
