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, that the fund’s operating expenses remain the same and that the expense reimbursement agreement remains in place for the contractual period. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

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 22% of the average value of its portfolio.

Principal Investment Strategies

The fund will invest in securities of issuers located throughout the world. Under normal circumstances, the fund will invest at least 80% of its assets in equity securities of issuers organized, headquartered or doing a substantial amount of business outside the U.S.

As of the date of this prospectus, the fund’s subadviser, Sustainable Growth Advisers, LP (“SGA”), considers an issuer that has at least 50% of its assets or derives at least 50% of its revenue from business outside the U.S. as doing a substantial amount of business outside the U.S. SGA uses an investment process to identify companies that it believes have a high degree of predictability, strong profitability and above average earnings and cash flow growth. SGA selects investments for the fund’s portfolio that it believes have superior long-term earnings prospects and attractive valuation. The fund’s equity investments may include common stocks, preferred stocks, securities convertible into or exchangeable for common stocks, and depositary receipts. The fund may invest in companies of all market capitalizations. The fund will allocate its assets among various regions and countries, including emerging markets. From time to time, the fund may have a significant portion of its assets invested in the securities of companies in only a few countries or regions. Although the fund seeks investments across a number of sectors, from time to time, the fund may have significant positions in particular sectors.

SGA will sell a portfolio holding when it believes the security’s fundamentals deteriorate, its valuation is no longer attractive, or a better investment opportunity arises.

Risk [Text Block]

Principal Risks

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.

Risk Lose Money [Member]

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.

Equity Securities Risk

> 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.

Foreign Investing Risk

> 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.

Emerging Market Risk

> Emerging Market Risk: Emerging markets securities may be more volatile, or more greatly affected by negative conditions, than those of their counterparts in more established foreign markets. Such securities may also be subject to Sanctions Risk.

Sanctions Risk

> Sanctions Risk: The imposition of sanctions and other similar measures could cause a decline in the value and/or liquidity of securities issued by or tied to the sanctioned country and increase market volatility and disruption in the sanctioned country and throughout the world. Sanctions and other similar measures could limit or prevent the fund from buying and selling securities (in the sanctioned country and other markets), significantly delay or prevent the settlement of transactions, and negatively impact the fund’s liquidity and performance.

Sector Focused Investing 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.

Market Volatility Risk

> 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), geopolitical risk, acts of terrorism, the spread of infectious illness or other public health issue, recessions, tariffs and other restrictions on trade, or the threat or potential of one or more such events and developments, 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.

Limited Number of Investments Risk

> 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.

Currency Rate 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.

Depositary Receipts Risk

> 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.

Convertible Securities Risk

> Convertible Securities Risk: The value of a convertible security may decline as interest rates rise and/or vary with fluctuations in the market value of the underlying securities. The security may be called for redemption at a time and/or price unfavorable to the fund.

Geographic Concentration Risk

> Geographic Concentration Risk: A fund that focuses its investments in a particular geographic location will be sensitive to financial, economic, political and other events negatively affecting that location and may cause the value of the fund to decrease, perhaps significantly.

Growth Stocks Risk

> Growth Stocks Risk: The fund’s investments in growth stocks may be more volatile than investments in other types of stocks, or may perform differently from the market as a whole and from other types of stocks.

Large Market Capitalization Companies Risk

> Large Market Capitalization Companies Risk: The value of investments in larger companies may not rise as much as smaller companies, or larger companies may be unable to respond quickly to competitive challenges, such as changes in technology and consumer tastes.

Preferred Stocks Risk

> Preferred Stocks Risk: Preferred stocks may decline in price, fail to pay dividends when expected, or be illiquid.

Redemption Risk

> 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

> 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.

Performance Information

The bar chart and table below provide some indication of the potential risks of investing in the fund. The fund’s past performance, before and after taxes, is not necessarily an indication of how the fund will perform in the future.

The bar chart shows changes in the fund’s and Predecessor Fund’s performance from year to year over a 10-year period. The table shows how the fund’s and Predecessor Fund’s average annual returns compare to those of a broad-based securities market index. Updated performance information is available at virtus.com or by calling 800-243-1574.

Performance for Class C Shares is not shown here as Class C Shares did not begin operations until March 11, 2024 and therefore had no performance for the periods shown.

The MSCI All Country World ex USA Index (net) is a free float-adjusted market capitalization-weighted index that measures equity performance of developed and emerging markets, excluding the United States. The index is calculated on a total return basis with net dividends reinvested. The index is unmanaged and not available for direct investment.

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. After-tax returns are shown only for Class I Shares; after-tax returns for other classes will vary. Actual after-tax returns depend on the investor’s tax situation and may differ from those shown. After-tax returns are not relevant to investors who hold fund shares in tax-deferred accounts or to shares held by non-taxable entities. In certain cases, the Return After Taxes on Distributions and Sale of Fund Shares for a period may be higher than other return figures for the same period. This will occur when a capital loss is realized upon the sale of fund shares and provides an assumed tax benefit that increases the return.

[1] The deferred sales charge is imposed on Class C Shares redeemed during the first year only.

[1] Estimated for current fiscal year, as annualized.

[2] The fund’s investment adviser has contractually agreed to limit the fund’s total operating expenses (excluding certain expenses, such as front-end or contingent deferred sales charges, taxes, leverage and borrowing expenses (such as commitment, amendment and renewal expenses on credit or redemption facilities), interest, brokerage commissions, expenses incurred in connection with any merger or reorganization, unusual or infrequently occurring expenses (such as litigation), acquired fund fees and expenses, and dividend expenses, if any) so that such expenses do not exceed 1.30% for Class A Shares, 2.05% for Class C Shares, 1.05% for Class I Shares and 0.95% for Class R6 Shares through April 30, 2026. Prior to April 30, 2026, only the fund’s Board may modify or terminate the expense limitation agreement. Following the contractual period, the adviser may discontinue these expense reimbursement arrangements at any time. Under certain conditions, the adviser may recapture operating expenses reimbursed and/or fees waived under these arrangements for a period of three years following the date such waiver or reimbursement occurred, provided that the recapture does not cause the fund to exceed its expense limit in effect at the time of the waiver or reimbursement, and any in effect at the time of recapture, after repayment is taken into account.
