<br> Summary Prospectus April 28, 2026 <br> <u>Virtus Newfleet Multi-Sector Intermediate Bond Series — Class A Shares</u>

This Summary Prospectus is intended for use in connection with a variable life insurance policy or a variable annuity contract and is not intended for use by other investors.<br>Before you invest, you may want to review the Series' prospectus, which contains more information about the Series and its risks. You can find the Series' prospectus, shareholder reports, statement of additional information (SAI), and other information about the Series online at www.virtus.com/investor-resources/variable-insurance-fund-documents. The Series' prospectus and SAI, both dated April 28, 2026 are incorporated by reference into this Summary Prospectus.<br>

#### Investment Objective
The Series has an investment objective of long-term total return.

#### Fees and Expenses
The following table describes the fees and expenses you may pay if you buy, hold and sell shares of the Virtus Newfleet Multi-Sector Intermediate Bond Series. The table does not include any fees or sales charges imposed under the variable contracts for which the Series is an investment option. If they were included, your costs would be higher.

---

| | |
|:---|:---|
| **Shareholder Fees *(fees paid directly from your investment)*** | **Class A** |
| Shareholder Fees |  |
| **Annual Series Operating Expenses *(expenses that you pay each year as a percentage of the value of your investment)*** | **Class A** |
| Management Fees | 0.50% |
| Distribution and/or Service (12b-1) Fees | 0.25% |
| Other Expenses | 0.23% |
| Total Annual Series Operating Expenses | 0.98% |
| Less: Fee Waiver and/or Expense Reimbursement<sup>(a)</sup> | (0.04)% |
| Total Annual Series Operating Expenses After Fee Waiver and/or Expense Reimbursement<sup>(a)</sup> | 0.94% |

---

(a) The Series' investment adviser has contractually
agreed to limit the Series' total annual operating expenses (excluding certain expenses, such as front-end
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 0.94% through
April 30, 2027. Prior to April 30, 2027, only the Series' Board may modify or terminate the expense limitation
agreement. Following the contractual period, the adviser may discontinue these expense reimbursement
arrangements at any time. 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 Series 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 Series with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Series for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year, that the Series' total operating expenses remain the same and that the expense reimbursement arrangement remains in place for the contractual period. The example does not reflect variable contract fees and charges, and if it did, the costs shown would be higher. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

---

| | | | | |
|:---|:---|:---|:---|:---|
| **Class** | **1 Year** | **3 Years** | **5 Years** | **10 Years** |
| Class A  | $96 | $308 | $538 | $1198 |

---

#### Portfolio Turnover
The Series 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. These costs, which are not reflected in Annual Series Operating Expenses or in the Example, affect the Series' performance. During the most recent fiscal year, the Series' portfolio turnover rate was 59% of the average value of its portfolio.

#### Investments, Risks and Performance

#### Principal Investment Strategies
The Series seeks to generate a competitive total return, inclusive of a high level of current income, by applying extensive credit research and a time-tested approach to capitalize on opportunities across undervalued sectors of the bond market. The Series seeks diversification across the full fixed income universe as described below in order to increase return potential and reduce risk.

------

Under normal circumstances, the Series invests at least 80% of its assets in fixed income securities. For purposes of this policy, indirect exposure to fixed income securities through investment in mutual funds and exchange-traded funds (ETFs) that invest in such securities will be considered to be investments by the Series in fixed income securities. Mutual funds and ETFs in which the Series invests may include affiliated funds that are also managed by the Series' subadviser. The Series seeks to achieve its objective by investing in a diversified portfolio of primarily intermediate-term bonds having a dollar-weighted average duration of between three and ten years and that are in one of the following market sectors:

 Securities issued or guaranteed as to principal and interest by the U.S. Government, its agencies, authorities or instrumentalities. Sectors include U.S. Treasuries and Agency Debentures;

 Collateralized mortgage obligations ("CMOs"), real estate mortgage investment conduits ("REMICs") and other pass-through securities, including those issued or guaranteed as to principal and interest by the U.S. Government, its agencies, authorities or instrumentalities. Sectors include Asset-backed Securities (ABS), Commercial Mortgage-Backed Securities (CMBS), Non-agency Residential Mortgage-Backed Securities (RMBS), and Agency Residential Mortgage-Backed Securities (MBS);

 Debt instruments issued by foreign issuers, including foreign governments and their political subdivisions and issuers located in emerging markets. Sectors include Emerging Markets Sovereign High Yield, Emerging Markets Sovereign Investment Grade, Emerging Markets Local Currency, Emerging Markets Corporates and Euro High Yield;

 Investment grade securities (primarily of U.S. issuers, secondarily of non-U.S. issuers), which are securities with credit ratings within the four highest rating categories of a nationally recognized statistical rating organization, including short-term securities. Sectors include Investment Grade Corporates, Municipals, and Taxable Municipals; and

 High-yield debt instruments (so-called "junk bonds"), including bank loans (which are generally floating-rate loans). Sectors include High Yield Corporates and Bank Loans, including both secured loans and "covenant lite" loans which have few or no financial maintenance covenants that would require a borrower to maintain certain financial metrics.

The Series may invest in all or some of these sectors.

The Series may use derivative instruments to increase or hedge (decrease) investment exposure to various fixed income sectors and instruments, including, but not limited to, swaps, futures contracts and currency forwards.

The Series manages duration utilizing a duration neutral strategy.

#### Principal Risks
The Series may not achieve its objective(s), and it is not intended to be a complete investment program. The value of the Series' 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 Series' 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 Series 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 separate accounts of participating insurance companies may impact the management of the Series and its ability to achieve its investment objective(s). The principal risks of investing in the Series 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.

> ***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.

> ***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.

> ***Foreign Investing Risk:*** Investing in foreign securities subjects the Series 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 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:*** 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 Series from buying and selling securities (in the sanctioned country and other markets), significantly delay or prevent the settlement of transactions, and negatively impact the Series' liquidity and performance.

> ***Mortgage-Backed and Asset-Backed Securities Risk:*** Changes in interest rates may cause both extension and prepayment risks for mortgage-backed and asset-backed securities. These securities are also subject to risks associated with the non-repayment of underlying collateral, including losses to the Series.

> ***Market Volatility Risk:*** The value of the securities in the Series 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

2<br>

------

restrictions on trade, or the threat or potential of one or more such events and developments, could have a significant impact on the Series and its investments, including hampering the ability of the Series' portfolio manager(s) to invest the Series' assets as intended.

> ***Affiliated Fund and ETF Risk:*** The Series' subadviser may select and substitute affiliated and/or unaffiliated mutual funds and/or exchange-traded funds (ETFs), which may create a conflict of interest because the subadviser or its affiliate(s) may receive fees from affiliated funds and/or ETFs, some of which pay the subadviser or its affiliate(s) more than others.

> ***Covenant Lite Loans Risk:*** The lack of financial maintenance covenants in covenant lite loans increases the risk that the fund will experience difficulty or delays in enforcing its rights on its holdings of such loans, which may result in losses, especially during a downturn in the credit cycle.

> ***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 Series may incur a loss greater than its principal investment.

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

#### > Long-Term Maturities/Durations Risk: Debt instruments with longer maturities or durations may experience greater price fluctuations than instruments having shorter maturities or durations.
> ***Municipal Securities Risk:*** Events negatively impacting a municipality, municipal security, or the municipal bond market in general, may cause the Series to decrease in value, perhaps significantly.

> ***Mutual Fund and ETF Investing Risk:*** The Series will be indirectly affected by factors, risks and performance specific to any other mutual fund and/or exchange-traded fund (ETF) ("underlying fund") in which it invests. Further, the net asset value per share of each underlying fund will include the effect of any fees and expenses of the underlying fund, so the Series' investment in such underlying funds will cause the Series to indirectly bear its proportionate share of such fees and expenses, which are reflected in the Series' Fees and Expenses table as "Acquired Fund Fees and Expenses" if they are estimated to amount to at least 0.01% of the Series' total net assets.

> ***Prepayment/Call Risk:*** Issuers may prepay or call their fixed rate obligations when interest rates fall, forcing the Series to reinvest in obligations with lower interest rates and the Series 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 Series, resulting in an adverse impact on remaining shareholders in the Series by causing the Series to take actions it would not otherwise have taken. The effects of taxable gains resulting from large redemptions of Series shares would particularly impact non-redeeming shareholders who do not hold their Series shares in a tax-advantaged or tax-exempt vehicle. Such large shareholder redemptions, which may occur rapidly or unexpectedly, may cause a Series to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Series' NAV and liquidity. In addition, a large redemption could result in the Series' current expenses being allocated over a smaller asset base, leading to an increase in the Series' expense ratio.

> ***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 Series' shares.

#### Performance Information
The following bar chart and table provide some indication of the risks of investing in the Series. The bar chart shows changes in the Series' performance from year to year over a 10-year period. The Series' past performance is not necessarily an indication of how the Series will perform in the future. The table shows how the Series' average annual returns compare to those of a broad-based securities market index. The Series' returns in the chart and table do not reflect the deduction of any separate account or variable contract charges. The returns would have been less than those shown if such charges were deducted. Updated performance information is available at virtus.com or by calling 800-367-5877.

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

The Series' subadviser is Newfleet Asset Management ("Newfleet"), 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 Series' portfolio.

> ***David L. Albrycht, CFA,*** Newfleet Division President and Chief Investment Officer and Senior Portfolio Manager at Newfleet, has managed the Series since 1998.

> ***Benjamin Caron, CFA,*** Senior Managing Director and Portfolio Manager at Newfleet, has managed the Series since May 2025.

#### Purchase and Sale of Series Shares
The Series does not offer its shares to the general public. The Series currently offers shares only to the separate accounts of participating insurance companies. Virtus Variable Insurance Trust (the "Trust"), of which the Series is a separate investment portfolio, has entered into an agreement with the insurance company sponsor of each separate account (participation agreement) setting forth the terms and conditions pursuant to which the insurance company will purchase and redeem shares of the Series. For information concerning the purchase of units of the separate accounts, see the variable contract prospectus.

#### Tax Information
Since the separate accounts are the only shareholders of the Series, no discussion is included herein as to the federal income tax consequences at the shareholder level. For information concerning the federal income tax consequences to the purchasers of variable contracts, see the variable contract prospectus which describes the particular separate account and variable contract.

#### Payments to Insurance Companies and Other Financial Intermediaries
Series shares are generally available only through intermediaries, i.e., the separate accounts. The Series (and/or its related companies) may pay the insurance companies (and/or their related companies) for distribution and/or other services; some of the payments may, in turn, go to broker-dealers and other financial intermediaries. For example, the Series may make payments for sub-transfer agency services to one or more of the insurance companies. Such payments may create a conflict of interest for an intermediary by influencing the intermediary's investment recommendations, or be a factor in the insurance company's decision to include the Series as an underlying investment option in a variable contract. Ask your salesperson or review your variable contract prospectus for more information.
