The fund seeks a high level of current income with lower volatility than the broader high yield market.

The tables below illustrate the fees and expenses that you may pay if you buy, hold and sell shares of the fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the tables and examples below. 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 59 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.”

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 54% of the average value of its portfolio.

The fund seeks to achieve its investment objective by normally investing at least 80% of its net assets (plus borrowings made for investment purposes) in debt securities issued by public and private companies, which are rated below investment grade (rated Ba or below by Moody’s or BB or below by S&P or Fitch, or if unrated, determined by the

fund’s subadviser to be of comparable quality) (sometimes referred to as “high-yield securities” or “junk bonds”), while maintaining an average duration of less than three years, and in derivatives and other synthetic instruments that have economic characteristics similar to such debt securities. Derivatives transactions may have the effect of either magnifying or limiting the fund’s gains and losses. To illustrate the effects of changes in interest rates on a portfolio with a similar average duration, generally, a portfolio with an average duration of three years would be expected to fall approximately 3% if interest rates rose by one percentage point.

The fund may invest up to 20% of its assets in bank loans. The fund may invest up to 20% of its assets in non-U.S. securities, which will typically be U.S. dollar-denominated but may also include securities denominated in non-U.S. currencies. The fund will invest less than 10% of its net assets in securities rated CCC or below by Standard and Poor’s.

The fund invests in high yield securities and bank loans, seeking to generate investment income while protecting from adverse market conditions and prioritizing capital preservation.

The portfolio managers apply a disciplined investment approach, making use of fundamental research, to construct a portfolio for investment. The subadviser uses an investment process that focuses on adding value through issue selection, sector/industry selection and opportunistic trading. The fund will generally overweight those sectors and industries where the subadviser identifies well-valued companies whose business profiles are viewed to be improving. In selecting specific debt instruments for investment, the portfolio managers may look to such factors as the issuer’s creditworthiness, the investment’s yield in relation to its credit quality and the investment’s relative value in relation to the high yield market. The portfolio managers seek to construct a portfolio with lower volatility than the broader high yield market in part through the fund’s approach to duration and credit quality. The portfolio managers may sell a security for a variety of reasons, such as to invest in a company offering superior investment opportunities.

The fund may utilize foreign currency exchange contracts, options, stock index futures contracts, warrants and other derivative instruments. Although the fund did not invest significantly in derivative instruments as of the most recent fiscal year end, it may do so at any time.

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 current subadviser commenced providing services for the fund in July 2022 and therefore the returns shown in the table for periods prior to that date reflect the performance of other investment professionals.

The bar chart shows changes in the fund’s performance from year to year over a 10-year period. The table shows how the fund’s average annual returns compare to those of a broad-based securities market index and a style-specific index that reflects the market sectors in which the fund invests.

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 (in alphabetical order after the first six risks).

> Debt Instruments Risk: Debt instruments are subject to greater levels of credit and liquidity risk, may be speculative and may decline in value due to changes in interest rates or an issuer’s or counterparty’s deterioration or default.

> 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.

> Interest Rate Risk: The values of debt instruments may rise or fall in response to changes in interest rates, and this risk may be enhanced for securities with longer maturities.

> Bank Loan Risk: In addition to the risks typically associated with high-yield/high-risk fixed income securities, bank loans may be unsecured or not fully collateralized, may be subject to restrictions on resale, may be less liquid and may trade infrequently on the secondary market. Bank loans settle on a delayed basis; thus, sale proceeds may not be available to meet redemptions for a substantial period of time after the sale of the loan.

> Counterparty Risk: There is risk that a party upon whom the fund relies to complete a transaction will default.

> Derivatives Risk: Derivatives and other similar instruments (collectively referred to in this section as “derivatives”) may include, among other things, futures, options, forwards and swap agreements and may be used in order to hedge portfolio risks, create leverage or attempt to increase returns. Investments in derivatives may result in increased volatility and the fund may incur a loss greater than its principal investment.

> 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.

> Liquidity Risk: Certain securities may be substantially less liquid than many other securities, such as U.S. Government securities or common stocks. To the extent the fund invests in less liquid securities or the level of liquidity in a particular market is constrained, the lack of an active market for investments may cause delay in disposition or force a sale below fair value.

> Prepayment/Call Risk: Issuers may prepay or call their fixed rate obligations when interest rates fall, forcing the fund to reinvest in obligations with lower interest rates and the fund may not benefit fully from the increase in value that other fixed income investments experience when interest rates decline.

> 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.

> U.S. Government Securities Risk: U.S. Government securities may be subject to price fluctuations. An agency may default on an obligation not backed by the full faith and credit of the United States. Any guarantee on U.S. government securities does not apply to the value of the fund’s shares.
