---

(a) 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 0.83% for Class A Shares and 0.58% for Class I Shares through January
31, 2027. Prior to January 31, 2027, 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.

#### 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:

---

| | | | | | |
|:---|:---|:---|:---|:---|:---|
| **Class**  | **Share Status** | **1 Year** | **3 Years** | **5 Years** | **10 Years** |
| Class A  | Sold or Held | $357 | $602 | $865 | $1617 |
| Class I  | Sold or Held | $59 | $255 | $467 | $1078 |

---

#### 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 35% of the average value of its portfolio.

#### Investments, Risks and Performance

#### Principal Investment Strategies
The fund seeks to generate current income exempt from federal income taxes by investing in a diversified portfolio with municipal bonds of varying maturities. The management team focuses on higher quality tax-exempt municipal bonds, gauging the value of a security by issue type, credit quality, and bond structure; however, the fund may invest up to 20% of its net assets in below investment grade tax-exempt municipal bonds. Below investment grade tax-exempt municipal bonds are considered high-yield/high-risk fixed income securities (so-called "junk bonds").

Under normal circumstances, as a matter of fundamental policy, the fund invests at least 80% of its assets in municipal bonds, the income from which is exempt from federal income taxes. The portion of the fund's assets not invested in tax-exempt securities may be invested in taxable fixed income securities. Income from these taxable investments may be subject to federal, state, and local taxes.

#### 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 or specific municipalities 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.

> ***Credit Risk:*** If the issuer of a debt instrument fails to pay interest or principal in a timely manner, or negative perceptions exist in the market of the issuer's ability to make such payments, the price of the security may decline.

> ***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.

> ***Municipal Securities Risk:*** Events negatively impacting a municipality, municipal security, or the municipal bond market in general, may cause the fund to decrease in value, perhaps significantly.

> ***High-Yield/High-Risk Fixed Income Securities (Junk Bonds) Risk:*** There is a greater risk of issuer default, less liquidity, and increased price volatility related to high-yield/high-risk securities than investment grade securities, and high-yield/high-risk securities are generally considered to be speculative.

> ***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.

> ***Income Risk:*** Income received from the fund may vary widely over the short- and long-term and/or be less than anticipated if the proceeds from maturing securities in the fund are reinvested in lower-yielding securities.

> ***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.

> ***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. The effects of taxable gains resulting from large redemptions of fund shares would particularly impact non-redeeming shareholders who do not hold their fund shares in a tax-advantaged or tax-exempt vehicle. Such large shareholder redemptions, which may occur rapidly or unexpectedly, may cause a fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the fund's NAV and liquidity. In addition, a large redemption could result in the fund's current expenses being allocated over a smaller asset base, leading to an increase in the fund's expense ratio.

> ***Tax-Exempt Securities Risk:*** Tax-exempt securities may not provide a higher after-tax return than taxable securities, and/or the tax-exempt status may be lost or limited.

> ***Tax Liability Risk:*** Noncompliant conduct by a municipal bond issuer, or certain adverse interpretations or actions by a government or tax authority, could cause interest from a security to become taxable, possibly retroactively, subjecting shareholders to increased tax liability.

#### Performance Information
The Virtus Seix Tax-Exempt Bond Fund, a series of Virtus Opportunities Trust ("Successor Fund"), is the successor of the Virtus Tax-Exempt Bond Fund, a series of Virtus Insight Trust ("Predecessor Fund"), resulting from a reorganization of the Predecessor Fund with and into the Successor Fund on September 23, 2016. The Predecessor Fund and the Successor Fund have identical investment objectives and strategies. The Successor Fund has adopted the past performance of the Predecessor Fund as its own. Therefore, the performance tables below include the performance of the shares of the Predecessor Fund prior to the Successor Fund's commencement date.

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 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 and more narrowly-based benchmark that reflect the market sectors in which the fund invests.

The Bloomberg Municipal Bond Index is a market capitalization-weighted index that measures the long-term tax-exempt bond market. The index is calculated on a total return basis. The index is unmanaged and not available for direct investment.

The ICE BofA 1-22 Year US Municipal Securities Index is a subset of the ICE BofA US Municipal Securities Index including all securities with a remaining term to final maturity less than 22 years, calculated on a total return basis. 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.

#### Management
The fund's investment adviser is Virtus Investment Advisers, LLC (formerly known as Virtus Investment Advisers, Inc.) ("VIA").

The fund's subadviser is Seix Investment Advisors ("Seix"), an operating division of Virtus Fixed Income Advisers, LLC, an affiliate of VIA.

#### Portfolio Management
The following individual is primarily responsible for the day-to-day management of the fund's portfolio.

> ***Dusty Self,*** Managing Director and Senior Portfolio Manager of Seix. Ms. Self has managed the fund since June 2022.

 $2,500, generally

 $100 for Individual Retirement Accounts (IRAs), systematic purchase or exchange accounts

 No minimum for defined contribution plans, asset-based fee programs, profit-sharing plans or employee benefit plans.

 $100, generally

 No minimum for defined contribution plans, asset-based fee programs, profit-sharing plans or employee benefit plans.

For Class I Shares, the minimum initial purchase is $100,000; there is no minimum for additional purchases.

The minimums may be reduced or waived in some circumstances. In general, you may buy or sell shares of the fund by mail or telephone on any business day. You also may buy and sell shares through a financial professional, broker-dealer or other financial intermediary.

#### Taxes
Distributions of net investment income attributed to the tax-exempt interest earned by the fund and designated as "exempt-interest dividends" will be exempt from the federal income tax. Such net investment income attributable to "private activity" bonds (other than private activity bonds issued in 2009 or 2010) may be a preference item for purposes of the federal alternative minimum tax. Income exempt from federal tax may be subject to state and local income tax. The fund may invest a portion of its assets in securities that generate income that is not exempt from federal or state income tax.

#### 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 broker-dealer or other intermediary and your financial professional to recommend the fund over another investment. Ask your financial professional or visit your financial intermediary's website for more information.
