Class/Ticker: V/VEEVX; I/VEEIX

Before you invest, you may want to review the Fund's prospectus, which contains more information about the Fund and its risks. You can find the Fund's Prospectus and other information about the Fund, including the Statement of Additional Information (SAI) and most recent reports to shareholders (when available), at no cost online at https://docs.venerable.com/#/venerable-variable-insurance-trust.

Investment Objective

The Venerable International Index Fund (the "Fund") seeks to replicate the performance of a benchmark index that measures the investment return of international developed markets stocks as closely as possible before the deduction of Fund expenses.

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy, hold, and sell shares of the Fund. You may pay other fees and expenses such as fees and expenses imposed under your variable annuity contracts or variable life insurance policies ("Variable Contract"), which are not reflected in the tables and examples below. If these fees or expenses were included in the table, the Fund's expenses would be higher. For more information on these charges, please refer to the documents governing your Variable Contract.

Annual Fund Operating Expenses

(expenses that you pay each year as a percentage of the value of your investment)

¹​ Based on estimated amounts for the current fiscal year.

²​ Until September 12, 2027, Venerable Investment Advisers, LLC (the "Adviser"), the distributor, and certain financial intermediaries have contractually agreed to waive all or a portion of fees (including management fee, administrative services fee, and/or distribution and/or service fee (12b-1 Fee), as applicable) and/or reimburse other operating expenses to the extent necessary to limit total annual operating expenses (excluding interest expenses, short sale expenses, taxes, brokerage commissions, and extraordinary expenses such as litigation expenses) to 0.70% for Class V shares and 0.46% for Class I shares. Termination or modification of these obligations prior to September 12, 2027, requires approval by the Fund's Board of Trustees (the "Board"). To the extent these obligations terminate or are modified, the Fund's total annual operating expenses may increase.

³​ Differs from the ratios of expenses to average net assets in the Financial Highlights section of the Prospectus due to rounding.

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 does not reflect expenses and charges which are, or may be, imposed under your Variable Contract. If the example were to reflect the deduction of such charges, the costs shown would be greater. 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. The example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. The example reflects the Fund's contractual fee waivers and reimbursement obligations only for the term of the fee waivers and reimbursement obligations. Although your actual costs and returns might 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 may indicate higher transaction costs. These costs, which are not reflected in the annual fund operating expenses or in the example above, affect the Fund's performance. During the period September 5, 2025 through December 31, 2025, the Fund's portfolio turnover rate was 5% of the average value of its portfolio.

Principal Investment Strategy

The Fund invests, under normal circumstances, at least 80% of its net assets (plus borrowings for investment purposes) in companies that are included in a benchmark index that measures the investment return of international developed market stocks. Typically, the actual percentage is considerably higher. The Fund uses an index-based investment approach designed to track the MSCI EAFE Index (the "Index"), a widely recognized benchmark of non-U.S. stock performance.

The Adviser has engaged Russell Investment Management, LLC ("RIM") to provide the day-to-day management of the Fund's portfolio pursuant to investment guidelines provided by the Adviser.

The Fund generally seeks to replicate the performance of the Index by giving approximately the same weight to a given security as the Index does. However, under extraordinary circumstances, the Fund may at times hold securities not included in the Index or may not hold securities in the same proportions as the Index (for example, as a result of corporate actions with respect to securities included in the Index (such as mergers and spin-offs), legal restrictions that apply to the Fund but not to the Index (such as diversification requirements), or liquidity considerations with respect to a security or extraordinary circumstances (such as if trading in a security has been halted)). The Fund may sell securities that are represented in the Index in anticipation of their removal from the Index or buy securities that are not yet represented in the Index in anticipation of their addition to the Index.

The Fund pursues a strategy of being fully invested by exposing its cash to the performance of the Index by purchasing index swaps and index futures contracts, which are derivatives. The Fund may enter into spot and forward currency contracts to facilitate settlement of securities transactions, which also are derivatives. The Fund may at times seek to protect a portion of its investments against adverse currency exchange rate changes by purchasing forward currency contracts.

The Fund may concentrate its investments (i.e., hold more than 25% of its total assets) in an industry or group of industries to the extent that the Index is so concentrated.

As of the date of this Prospectus, a significant portion of the Index consisted of securities of companies in the financials sector.

The Fund is classified as a diversified investment company, as defined in the Investment Company Act of 1940, as amended (the "1940 Act"). However, the Fund may become non-diversified under the 1940 Act without the approval of shareholders solely as a result of change in relative market capitalization or index weighting of one or more constituents of the Index. A non-diversified fund generally invests a greater portion of its assets in a limited number of issuers relative to a diversified fund. The Fund may be non-diversified for an indefinite period.

Principal Risks of Investing

As with all mutual funds, an investor is subject to the risk that his or her investment could lose money. In addition to this risk, the Fund is subject to the principal risks described below.

• Equity Securities Risk. The value of equity securities will rise and fall in response to the activities of the company that issued them, general market conditions and/or economic conditions.

• Non-U.S. Securities Risk. Non-U.S. securities have risks relating to political, economic, social, and regulatory conditions in foreign countries. Non-U.S. securities may also be subject to risk of loss because of more or less foreign government regulation, less public information and less stringent investor protections and disclosure standard. In addition, the value of non-U.S. securities may be subject to foreign tax laws including withholding taxes, which may reduce the net amount available for distribution to the Fund's shareholders.

• Currency Risk. Non-U.S. securities that trade in, and receive revenues in, non-U.S. currencies are subject to the risk that those currencies will decline in value relative to the U.S. dollar or, in the case of hedging positions, that the U.S. dollar will decline in value relative to the currency being hedged. As a result, investments in non-U.S. dollar-denominated securities and currencies may reduce the returns of the Fund.

• Financial Markets Risk. Global economies and financial markets are increasingly interconnected and conditions (including volatility and instability) and events (including natural disasters, pandemics, and epidemics) in one country, region or financial market may adversely impact issuers in a different country, region, or financial market. In addition, governmental and quasi-governmental organizations have taken a

number of unprecedented actions designed to support the markets. Such events and conditions may adversely affect the value of the Fund's securities, result in greater market or liquidity risk or cause difficulty valuing the Fund's portfolio instruments or achieving the Fund's objective.

• Derivatives Risk. Investments in a derivative instrument could lose more than the initial amount invested. Compared to conventional securities, derivatives can be more sensitive to changes in interest rates or to sudden fluctuations in market prices and thus the Fund's losses may be greater if it invests in derivatives than if it invests only in conventional securities. The use of derivative instruments involves risks different from, and possibly greater than, the risks associated with investing directly in equity or fixed income securities, currencies, or other instruments. Derivatives are generally subject to a number of risks such as leveraging risk, liquidity risk (the risk that the investment cannot be sold quickly), market risk, credit risk, default risk, counterparty risk (the risk that the other party in an agreement will fail to perform its obligations), management risk, operational risk, and legal risk. Certain of these risks do not apply to derivative instruments entered into for hedging or cash equitization, certain cleared derivative instruments, and written options contracts. Derivatives also involve the risk of mispricing or improper valuation and the risk that changes in the value of the derivative instrument may not correlate exactly with the change in the value of the underlying asset, rate, or index.

• Index-Based Investing Risk. The Fund uses an index replication strategy to seek to purchase the securities in an index (the "reference index") in order to track the reference index's performance. The Fund will generally hold constituent securities of the reference index regardless of the current or projected performance of a specific security or a particular industry or market sector. Maintaining investments in securities regardless of the performance of individual securities or market conditions could cause the Fund's return to be lower than if the Fund employed a fundamental investment approach to security selection. Additionally, index-based strategies are subject to "tracking error" risk, which is the risk that the performance of the Fund will differ from the performance of the reference index it seeks to track due to differences in security holdings, operating expenses, transaction costs, cash flows and operational inefficiencies.

• Depositary Receipts Risk. Depositary receipts (including American Depositary Receipts and Global Depositary Receipts) are securities traded on a local stock exchange that represent securities issued by a foreign publicly-listed company. Depositary receipts are generally subject to the same risks of investing in the foreign securities they evidence or into which they may be converted.

• Financials Sector Risk. To the extent that the Fund invests significantly in the financials sector, the Fund may be susceptible to adverse economic or regulatory occurrences affecting the financials sector, including with respect to U.S. and foreign banks, broker-dealers, insurance companies, finance companies (e.g., automobile finance) and related asset-backed securities. These developments may affect the value of the Fund's investments more than if the Fund was not invested to such a degree in this sector. Companies in the financials sector may be particularly susceptible to factors such as interest rate, fiscal, regulatory and monetary policy changes.

• Currency Trading Risk. Currency trading strategies may involve instruments that have volatile prices, are illiquid or less liquid or create economic leverage. Forward currency contracts are subject to the risk that, should forward prices increase, a loss will be incurred to the extent that the price of the currency agreed to be purchased exceeds the price of the currency agreed to be sold.

• Industry Concentration Risk. To the extent the Index (and therefore, the Fund) concentrates its investments in one or more industries, the Fund will carry much greater risk of adverse developments in those industries than a fund that invests in a wide variety of industries.

• Non-Diversification Risk. To the extent the Fund becomes non-diversified, the Fund may invest a relatively high percentage of its assets in a limited number of issuers. Therefore, when the Fund is non-diversified, the Fund's performance may be more vulnerable to changes in the market value of a single issuer or group of issuers and more susceptible to risks associated with a single economic, political or regulatory occurrence than when the Fund's invested assets are diversified.

• Impact of Large Redemptions (Including Possible Fund Liquidation) Risk. The Fund is used as an investment by certain funds of funds and may have a large percentage of its shares owned by such funds. Large redemption activity could result in the Fund incurring additional costs and being forced to sell portfolio securities at a loss to meet redemptions. Large redemptions may also result in increased expense

ratios, higher levels of realized capital gains or losses with respect to the Fund's portfolio securities, higher Fund cash levels, higher brokerage commissions and other transaction costs, among other negative consequences such as reduced liquidity in the Fund's portfolio. As a result, large redemption activity could adversely affect the Fund's ability to conduct its investment program which, in turn, could adversely impact the Fund's performance or may result in the Fund no longer remaining at an economically viable size, in which case the Fund may cease operations.

An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Performance Information

Performance information is not provided because the Fund did not complete one full calendar year of operations as of the date of this Prospectus. Once the Fund has completed a full calendar year of operations, a bar chart and table will be included that will provide some indication of the risks of investing in the Fund by comparing the Fund's return to a broad measure of market performance.

Investment Adviser

The Adviser serves as the investment adviser to the Fund.

Sub-Adviser

RIM serves as discretionary investment sub-adviser to the Fund.

Portfolio Managers

The individual members of the team jointly and primarily responsible for the day-to-day management of the Fund are:

Purchase and Sale of Fund Shares

Shares of the Fund are not offered directly to the public. Purchase and sale of shares may be made only by separate accounts of insurance companies serving as investment options under Variable Contracts. Please refer to the prospectus for the appropriate Variable Contract for information on how to direct investments in, or sale from, an investment option corresponding to the Fund and any fees that may apply. Participating insurance companies and certain other designated organizations are authorized to receive purchase orders on the Fund's behalf.

Shares of the Fund also may be sold directly to other investment companies.

Tax Information

Distributions made by the Fund to a Variable Contract, and exchanges and redemptions of Fund shares made by a Variable Contract, ordinarily do not cause the corresponding contract holder or plan participant to recognize income or gain for federal income tax purposes. See the prospectus for the appropriate Variable Contract for information regarding the federal income tax treatment of the distributions to your Variable Contract and the holders of the Variable Contracts.

Payments to Insurance Companies and Other Financial Intermediaries

Class V shares and Class I shares of the Fund may be offered as investment options in Variable Contracts issued by affiliated and non-affiliated insurance companies. Fees derived from a Fund's Distribution Plan (if applicable) may be paid to insurance companies, broker-dealers, and other financial intermediaries for selling the Fund's shares to the clients of the insurance companies, broker-dealers, or other financial intermediaries. See "Distribution Plan."

In addition, the Adviser or its affiliated entities, out of their own resources and without additional cost to the Fund or its shareholders, may pay additional compensation to these insurance companies, broker-dealers, or other financial intermediaries. Payments of such additional compensation may provide an incentive for insurance companies to make the Fund available through Variable Contracts over other mutual funds or products. As of the date of this Prospectus, the Adviser and its affiliated entities have not entered into any such arrangements.

The Adviser and its affiliated entities may also share their profits with affiliated insurance companies or other affiliated entities through inter-company payments. The sharing of such profits may provide an incentive for affiliated insurance companies to make the Fund available through Variable Contracts over other mutual funds or products. As of the date of this Prospectus, the Adviser intends to share all of its profits with affiliated insurance companies.

The insurance companies issuing Variable Contracts may also pay fees to third parties in connection with distribution of the Variable Contracts and for services provided to Contract Owners. Neither the Fund, the Adviser, nor the Fund's distributor are parties to these arrangements. Contract Owners should consult the prospectus and statement of additional information for their Variable Contracts for a discussion of these payments and should consult with their agent or broker.
