Fees and Expenses

This table describes the fees and expenses that you may pay if you buy, hold, and sell shares of the Fund. Sales charges and other expenses that may be imposed by variable insurance contracts are not included. If these charges were reflected, the expenses listed below would be higher. See the variable insurance contract prospectus, which may impose sales charges and other additional contract-level expenses.

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

	Class I Shares	Class II Shares
Management Fees	0.60%	0.60%
Distribution and/or Service (12b-1) Fees	None	0.25%
Other Expenses	0.22%	0.07%
Total Annual Fund Operating Expenses	0.82%	0.92%
Fee Waiver/Expense Reimbursement(1)	(0.05)%	(0.05)%
Total Annual Fund Operating Expenses After Fee Waiver/Expense Reimbursement	0.77%	0.87%

(1) Nationwide Variable Insurance Trust (the “Trust”) and Nationwide Fund Advisors (the “Adviser”) have entered into a written contract waiving 0.055% of the management fee to which the

Adviser would otherwise be entitled until April 30, 2027. The written contract may be changed or eliminated only with the consent of the Board of Trustees of the Trust.

Example

This Example is intended to help you to compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example, however, does not include charges that are imposed by variable insurance contracts. If these charges were reflected, the expenses listed below would be higher.

This Example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your shares at the end of those time periods. It assumes a 5% return each year and no change in expenses, and any expense limitation or fee waivers that may apply for the periods indicated above under “Fees and Expenses.” Although your actual costs may be higher or lower, based on these assumptions your costs would be:

	1 Year	3 Years	5 Years	10 Years
Class I Shares	$79	$257	$450	$1,009
Class II Shares	89	288	504	1,127

NVIT Jacobs Levy Large Cap Core Fund

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. 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 89.97% of the average value of its portfolio.

Principal Investment Strategies

Under normal circumstances, the Fund invests at least 80% of its net assets in equity securities issued by large capitalization companies. For these purposes, equity securities represent an ownership interest in an issuer, and large capitalization companies are those with market capitalizations similar to those of companies included in the S&P 500® Index. Equity securities in which the Fund invests are primarily common stock. The Fund may also invest in equity securities of companies that are located outside the United States.

The subadviser invests in stocks using a dynamic, multidimensional investment process that combines human insight and intuition, finance and behavioral theory, and quantitative and statistical techniques. The subadviser’s security evaluation process focuses on modeling a large number of stocks and proprietary factors, using financial statements, security analyst forecasts, corporate management signals, economic releases, and security prices. This investment approach is intended to seek diversification across market inefficiencies, securities, industries, and sectors, while managing known risk exposures relative to the S&P 500® Index. The range of models is designed to allow the portfolio to be diversified across exposures to numerous potential opportunities. Nevertheless, the Fund may invest in any economic sector and, at times, emphasize one or more particular industries or sectors.

The subadviser generally considers selling a stock when the return prediction generated by its models, adjusted for risk and expected transaction costs, is notably surpassed by another stock’s return prediction. Partial sales may occur when the subadviser’s investment process determines that these transactions could benefit portfolio performance or when, as a result of market action, a position has grown to a size that impinges on portfolio risk or liquidity limitations. Sales may also occur under special circumstances; for example, if a company agrees to be acquired, and trades as a merger arbitrage situation, its stock may be sold. Sales can be triggered when necessary valuation data are no longer available; for example, if all security analysts drop coverage of a stock, the position may be sold. Also, a position may be trimmed or closed as a result of the subadviser's compliance monitoring process if, for example, a security or sector weight exceeds a relevant guideline. The Fund may engage in active and frequent trading of portfolio securities.

Principal Risks

The Fund cannot guarantee that it will achieve its investment objective.

As with any fund, the value of the Fund’s investments—and therefore, the value of Fund shares—may fluctuate. These changes may occur because of:

Equity securities risk – stock markets are volatile. The price of an equity security fluctuates based on changes in a company’s financial condition and overall market and economic conditions.

Market risk – the risk that one or more markets in which the Fund invests will go down in value, including the possibility that the markets will go down sharply and unpredictably. This occurs due to numerous factors, including interest rates, the outlook for corporate profits, the health of the national and world economies, and the fluctuation of other securities markets around the world. These risks may be magnified if certain social, political, economic and other conditions and events (such as natural disasters, epidemics and pandemics, terrorism, conflicts, trade disputes and social unrest or rapid technological developments such as artificial intelligence) adversely interrupt the global economy.

Selection risk – the risk that the securities selected by the Fund’s subadviser will underperform the markets, the relevant indexes or the securities selected by other funds with similar investment objectives and investment strategies.

Quantitative analysis strategy risk – the success of the Fund's investment strategy depends in part on the effectiveness of the subadviser's quantitative tools for screening securities. These strategies may incorporate factors that are not predictive of a security's value. Additionally, a previously successful strategy may become outdated or inaccurate, possibly resulting in losses.

Foreign securities risk – foreign securities often are more volatile, harder to price and less liquid than U.S. securities. The prices of foreign securities may be further affected by other factors, such as changes in the exchange rates between the U.S. dollar and the currencies in which the securities are traded.

Sector risk – investments in particular industries or sectors may be more volatile than the overall stock market. Therefore, if the Fund emphasizes one or more industries or economic sectors, it will be more susceptible to financial, market or economic events affecting the particular issuers and industries participating in such sectors than funds that do not emphasize particular industries or sectors.

Model and data risk – the Fund’s subadviser relies heavily on quantitative models and information and data supplied or made available by third parties (“Models and Data”). Models and Data are used to construct sets of transactions and investments and, to provide risk management insights.

When Models and Data prove to be incorrect or incomplete, including because data is stale, missing or unavailable, any decisions made in reliance thereon expose the Fund to potential risks. Some of the models used by the subadviser for the Fund are predictive in nature. The use of predictive models has inherent risks. Because predictive models are usually constructed based on historical data supplied by third parties, the success of relying on such models depends heavily on the accuracy and reliability of the supplied historical data. The Fund bears the risk that the quantitative models used by the subadviser will not be successful in selecting companies for investment or in determining the weighting of investment positions that will enable the Fund to achieve its investment objective.

All models rely on correct data inputs. If incorrect data is entered into even a well-founded model, the resulting information will be incorrect. However, even if data is inputted correctly, “model prices” will often differ substantially from market prices.

The Fund is unlikely to be successful unless the assumptions underlying the models are realistic and either remain realistic and relevant in the future or are adjusted to account for changes in the overall market environment. If such assumptions are inaccurate or become inaccurate and are not promptly adjusted, it is likely that profitable trading signals will not be generated, and major losses may result.

The subadviser, in its sole discretion, will continue to test, evaluate and add new models, which may result in the modification of existing models from time to time. There can be no assurance that model modifications will enable the Fund to achieve its investment objective.

Portfolio turnover risk – a higher portfolio turnover rate increases transaction costs and may adversely impact the Fund’s performance.

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

Performance

The following bar chart and table provide some indication of the risks of investing in the Fund. The bar chart shows the volatility or variability of the Fund’s annual total returns over time and shows that Fund performance can change from year to year. The table shows the Fund’s average annual total returns for certain time periods compared to the returns of a broad-based securities market index. Remember, however, that past performance is not necessarily an indication of how the Fund will perform in the future. The returns shown in the bar chart and table do not include charges that will be imposed by variable insurance contracts. If these amounts were reflected, returns would be less than those shown.

The Fund's performance prior to February 21, 2023, reflects returns pursuant to a different subadviser. If the Fund's current subadviser had been in place for the prior period, the performance information shown would have been different.

Tax Information

The dividends and distributions paid by the Fund to the insurance company separate accounts will consist of ordinary income, capital gains, or some combination of both. Because shares of the Fund must be purchased through separate accounts used to fund variable insurance contracts, such dividends and distributions will be exempt from current taxation by contract holders if left to accumulate within a separate account. Consult the variable insurance contract prospectus for additional tax information.

Payments to Broker-Dealers and Other Financial Intermediaries

This Fund is only offered as an underlying investment option for variable insurance contracts. The Fund and its related companies may make payments to the sponsoring insurance companies (or their affiliates) for distribution and/or other services, and to broker-dealers and other financial intermediaries that distribute the variable insurance contracts. These payments may create a conflict of interest by influencing the insurance companies to include the Fund as an underlying investment option in the variable insurance contracts, and by influencing the broker-dealers and other financial intermediaries to distribute variable insurance contracts that include the Fund as an underlying investment option over other variable insurance contracts or to otherwise recommend the selection of the Fund as an underlying investment option by contract owners instead of other funds that also may be available investment options. The prospectus (or other offering document) for your variable insurance contract may contain additional information about these payments.
