Fund Summary: Nationwide Bailard Cognitive Value Fund (cont.)
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 283.03% of the average value of its portfolio.
Principal Investment Strategies
The Fund will, under normal market conditions, invest its assets primarily in common stocks of small-cap value companies that are within a market capitalization range that is similar, although not identical, to the market capitalization range of those companies found in the Russell 2000® Value Index. Under normal market conditions, the Fund may invest up to 25% of the Fund’s net assets in common stocks of micro-cap companies whose market capitalization, measured at the time of purchase, is $300 million or less. There is no minimum market capitalization limit for the companies in which the Fund may invest. The Fund’s subadviser seeks to add value to the Fund’s portfolio through stock selection while maintaining a risk profile that is appropriate relative to the Russell 2000® Value Index. The subadviser uses both quantitative and qualitative techniques to identify stocks it believes are currently undervalued by the market but which still have good fundamentals.
As part of the portfolio management of the Fund, the subadviser employs Behavioral Finance techniques in an attempt to capitalize on investors’ behavioral biases and cognitive errors that can result in securities being mispriced. Behavioral Finance is the study of why people do not always behave in an economically rational manner. Economic irrationality typically arises from investors maximizing personal benefit (not wealth), emotional investing, heuristic biases (e.g., “trial and error” or “rule of thumb” biases) and cognitive errors. The subadviser attempts to exploit investors’ biases and errors that it believes to be recurring and predictable, and to minimize its own susceptibility to these same biases and errors. In addition to evaluating traditional risk measures, the subadviser assesses the risk profiles of environmental, social and governance (“ESG”) factors on companies in which the Fund may invest. The subadviser’s assessment is based on a proprietary scoring matrix to rate each company in the investable universe based on its potential exposure to ESG risk factors. Companies that the subadviser perceives as having high levels of ESG risk and/or significant negative externalities associated with their products or services may
be excluded from investment consideration. At times the subadviser emphasizes certain industries or sectors. The Fund may invest up to 25% of its net assets in U.S. dollar-denominated stocks of foreign companies.
The Fund may also 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 stock 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 and social unrest) 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.
Smaller company risk – smaller companies are usually less stable in price and less liquid than larger, more established companies. Smaller companies are more vulnerable than larger companies to adverse business and economic developments and may have more limited resources. Therefore, they generally involve greater risk.
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.
Micro-cap risk – investing in micro-cap companies involves greater risk than investing in small-, medium- or large- capitalization companies because the stocks of micro-cap companies tend to have greater price volatility and less
3

Fund Summary: Nationwide Bailard Cognitive Value Fund (cont.)
liquidity than the stocks of larger companies. In addition, micro-cap companies tend to have smaller financial resources, less information available, more limited business lines and more geographic area concentration.
Value style risk – value investing carries the risk that the market will not recognize a security’s intrinsic value for a long time or that a stock judged to be undervalued actually is appropriately priced. In addition, value stocks as a group sometimes are out of favor and underperform the overall equity market for long periods while the market concentrates on other types of stocks, such as “growth” stocks.
Behavioral Finance techniques risk – the criteria used in implementing Behavioral Finance techniques and the weight placed on those criteria may not be predictive of a security’s value, and the effectiveness of the criteria can change over time. There can be no guarantee that the subadviser will be successful in applying Behavioral Finance techniques to successfully predict investor behavior to exploit stock price anomalies, and the Fund may underperform funds that do not employ such techniques.
Foreign securities risk – foreign securities often are more volatile, harder to price and less liquid than U.S. securities.
Environmental, Social and Governance investing risk – the risk that, because the Fund’s ESG strategy will select or exclude securities of certain issuers for reasons other than investment performance, the Fund’s performance will differ from or underperform compared to funds that do not utilize an ESG investing strategy. ESG investing is qualitative and subjective by nature, and there is no guarantee that the factors utilized by the Fund’s subadviser or any judgment exercised by the subadviser will reflect the opinions of any particular investor.
Portfolio turnover risk – a higher portfolio turnover rate increases transaction costs, may adversely impact the Fund’s performance, and may result in higher taxes when Fund shares are held in a taxable account.
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 Fund has adopted the historical performance of the HighMark Cognitive Value Fund, a former series of HighMark Funds (the “Predecessor Fund”) as the result of a reorganization in which the Fund acquired all of the assets, subject to the liabilities, of the Predecessor Fund on September 16, 2013. The returns presented for periods prior to September 16, 2013 reflect the performance of the Predecessor Fund. At the time of the reorganization, the
Fund and the Predecessor Fund had substantially similar investment goals and strategies.
The following bar chart and table can help you evaluate the Fund’s potential risks. The bar chart shows how the Fund’s annual total returns have varied from year to year. The table compares the Fund’s average annual total returns to the returns of a broad-based securities index. Remember, however, that past performance (before and after taxes) is not necessarily indicative of how the Fund will perform in the future. Updated performance information is available at no cost by visiting nationwide.com/mutualfunds or by calling 800-848-0920.
Sales charges are not reflected in the bar chart, and if those charges were included, returns would be less than those shown.

Tax Information
The Fund’s distributions are taxable, and generally will be taxed as ordinary income, capital gains, or some combination of both, unless you are investing through a tax-advantaged arrangement, such as a 401(k) plan or an individual retirement account, in which case your distributions may be taxed as ordinary income when withdrawn from the tax-advantaged account.
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 salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.

Fund Summary: Nationwide Bailard Technology & Science Fund (cont.)
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 20.23% of the average value of its portfolio.
Principal Investment Strategies
The Fund will, under normal market conditions, invest its assets primarily in common stocks located in the United States and abroad that the subadviser believes have superior sales and earnings growth potential, but at a reasonable price. It is expected that, under normal market conditions, the Fund will invest at least 80% of its net assets in established companies in the technology and science sectors, including in the semiconductor, semiconductor equipment, hardware, software, information technology services, communications equipment, social media, biotechnology, healthcare, financial technology, and interactive media sectors, and may invest in other sectors if determined by the Fund’s subadviser to be in the Fund’s best interests. The Fund may also invest up to 25% of its net assets in U.S. dollar denominated stocks of foreign companies located in both developed and emerging markets.
Using a combination of qualitative and quantitative techniques, the Fund’s subadviser seeks to identify those securities it believes offer superior sales and earnings growth prospects at a reasonable valuation. The subadviser seeks to add value to the Fund’s portfolio through stock selection. In addition to evaluating traditional risk measures, the subadviser assesses the risk profiles of environmental, social and governance (“ESG”) factors on companies in which the Fund may invest. The subadviser's assessment is based on a proprietary scoring matrix to rate each company in the investable universe based on its potential exposure to ESG risk factors. Companies that the subadviser perceives as having high levels of ESG risk and/or significant negative externalities associated with their products or services may be excluded from investment consideration. The subadviser may also consider market indices and its own estimates of competitor portfolio weightings in managing the Fund’s portfolio.
The Fund may also invest opportunistically in initial public offerings (“IPOs”) and in securities of new public companies that have had their IPO within the last six months and that the subadviser finds attractive. The subadviser seeks investment opportunities to penetrate new and existing
markets specifically within the technology, biotechnology and other growth industries. In looking at particular companies, the subadviser evaluates the scope of business of a company and its competitive landscape, as well as its management team’s experience.
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 stock 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 and social unrest) 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.
Growth style risk – growth stocks are generally more sensitive to market movements than other types of stocks primarily because their stock prices are based heavily on future expectations. If the subadviser’s assessment of the prospects for a company’s growth is wrong, or if the subadviser’s judgment of how other investors will value the company’s growth is wrong, then the Fund will suffer a loss as the price of the company’s stock may fall or not approach the value that the subadviser has placed on it. In addition, growth stocks as a group sometimes are out of favor and underperform the overall equity market for long periods while the market concentrates on other types of stocks, such as “value” stocks.
Sector risk – investments in particular industries or sectors may be more volatile than the overall stock market. Because the Fund’s investment universe consists of securities in the semiconductor, semiconductor equipment, hardware, software, information technology services,
7

Fund Summary: Nationwide Bailard Technology & Science Fund (cont.)
communications equipment, social media, biotechnology and interactive media sectors, the Fund has a heavy weighting in these sectors.
The Fund’s investments in technology and science related sectors expose the Fund to risks associated with economic conditions in the technology and science markets to a greater extent than funds that do not invest heavily in these sectors. Due to intense global competition, a less diversified product line and other factors, companies that develop and/or rely on technology are often highly sensitive to downswings in the economy. Such companies may also experience volatile swings in demand for their products and services due to changing economic conditions, rapid technological advances and shorter product lifespans.
Initial public offering risk – availability of IPOs may be limited and the Fund may not be able to buy any shares at the offering price, or may not be able to buy as many shares at the offering price as it would like, which may adversely impact Fund performance. Further, IPO prices often are subject to greater and more unpredictable price changes than more established stocks.
New public company risk – the risks associated with investing in new public companies include small size, limited financial resources and operating history, dependence on a limited number of products and markets and lack of management depth.
Foreign securities risk – foreign securities often are more volatile, harder to price and less liquid than U.S. securities.
Emerging markets risk – emerging markets are riskier than more developed markets because they tend to develop unevenly and may never fully develop. Investments in emerging markets are considered speculative. Emerging markets are more likely to experience hyperinflation and currency devaluations, which adversely affect returns to U.S. investors. In addition, many emerging securities markets have far lower trading volumes and less liquidity than developed markets. Since these markets are smaller than developed markets, they may be more likely to suffer sharp and frequent price changes or long-term price depression because of adverse publicity, investor perceptions or the actions of a few large investors. Practices in relation to settlement of securities transactions in emerging markets involve higher risks than those in developed markets, in part because the Fund will need to use brokers and counterparties that are less well capitalized, and custody and registration of assets in some countries are unreliable compared to developed markets. Companies in emerging market countries generally are subject to less stringent financial reporting, accounting and auditing standards than companies in more developed countries. In addition, information about such companies may be less available and reliable. Many emerging markets also have
histories of political instability and abrupt changes in policies, and the ability to bring and enforce actions may be limited. Certain emerging markets also face other significant internal or external risks, including the risk of war, nationalization of assets, unexpected market closures and ethnic, religious and racial conflicts.
Environmental, Social and Governance investing risk – the risk that, because the Fund’s ESG strategy will select or exclude securities of certain issuers for reasons other than investment performance, the Fund’s performance will differ from or underperform compared to funds that do not utilize an ESG investing strategy. ESG investing is qualitative and subjective by nature, and there is no guarantee that the factors utilized by the Fund’s subadviser or any judgment exercised by the subadviser will reflect the opinions of any particular investor.
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.

After-tax returns are not relevant to investors in tax-advantaged arrangements, such as individual retirement accounts, 401(k) plans or certain other employer-sponsored retirement plans.
Historical performance for Class A, Class C, Class M and Institutional Service Class shares is based on the previous performance of Class A, Class C, Class M and Fiduciary Class Shares, respectively, of the Predecessor Fund.
The inception date for Class R6 shares is September 18, 2013. Therefore, pre-inception historical performance of Class R6 shares is based on the previous performance of the Predecessor Fund’s Fiduciary Class Shares. Performance for Class R6 shares has not been adjusted to reflect that share class’s lower expenses than those of the Predecessor Fund’s Fiduciary Class Shares.

Nationwide Mutual Funds (the “Trust”) and Nationwide Fund Advisors (the “Adviser”) have entered into a written contract limiting annual fund operating expenses to 0.66% until at least February 29, 2024. Under the expense limitation agreement, the level to which operating expenses are limited applies to all share classes, excluding any taxes, interest, brokerage commissions, Rule 12b-1 fees, acquired fund fees and expenses, short-sale dividend expenses, administrative services fees, other expenses which are capitalized in accordance with generally accepted accounting principles and expenses incurred by the Fund in connection with any merger or reorganization, and may exclude other nonroutine expenses not incurred in the ordinary course of the Fund’s business. The expense limitation agreement may be changed or eliminated only with the consent of the Board of Trustees of the Trust. The Adviser may request and receive reimbursement from the Fund for advisory fees waived or other expenses reimbursed by the Adviser pursuant to the expense limitation agreement at a date not to exceed three years from the date in which the corresponding waiver or reimbursement to the Fund was made. However, no reimbursement may be made unless: (i) the Fund’s assets exceed $100 million and (ii) the total annual expense ratio of the class making such reimbursement is no higher than the amount of the expense limitation that was in place at the time the Adviser waived the fees or reimbursed the expenses and does not cause the expense ratio to exceed the current expense limitation. Reimbursement by the Fund of amounts previously waived or reimbursed by the Adviser is not permitted except as provided for in the expense limitation agreement.

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 77.47% of the average value of its portfolio.
Principal Investment Strategies
The Fund seeks to provide investors with total return, consisting of capital appreciation and/or income, by outperforming the Russell 1000® Value Index over a full market cycle while maintaining a similar level of market risk as the index. To achieve this goal, the Fund’s subadviser seeks to identify and construct the most optimal portfolio that targets an equity-like level of volatility by allocating assets among equity securities, money market instruments, futures contracts the value of which are derived from the performance of equity indexes and U.S. Treasury bonds (which are government-issued fixed income securities), and options on equity index and U.S. Treasury bond futures. Futures and options are derivatives and expose the Fund to leverage. In addition, the Fund may write (sell) covered call options to enhance returns and/or to limit volatility. Investors in the Fund should have a long-term perspective and be able to tolerate potentially sharp declines in value.
The Fund invests, under normal circumstances, at least 80% of its net assets in equity securities, primarily common stocks. Equity securities also may include preferred stocks, convertible securities and derivatives the value of which are linked to equity securities. The Fund also may invest up to 20% of its net assets in equity securities of foreign companies, which are companies organized under the laws of countries other than the United States. Although the Fund typically invests in seasoned issuers, it may, depending on the appropriateness to the Fund's strategy
and availability in the marketplace, purchase securities of companies in initial public offerings (IPOs) or shortly thereafter, which can be subject to greater volatility than seasoned issuers.
The subadviser’s investment process is designed to provide investors with investment exposure to sector weightings and risk characteristics generally similar to those of the Russell 1000® Value Index, although the Fund may emphasize one or more particular sectors at times.
The Fund’s subadviser employs a value style of investing, focusing on dividend-paying stocks and other investments and investment techniques that provide income. The subadviser identifies potential investments through extensive quantitative and fundamental analysis, using a bottom-up approach that emphasizes three key factors:
Value: quantitative screens track traditional measures, such as price-to-earnings, price-to-book and price-to-sales ratios, which are analyzed and compared against the market;
Sound business fundamentals: a company's balance sheet and income data are examined to determine the company's financial history; and
Positive business momentum: a company's earnings and forecast changes are analyzed and sales and earnings trends are reviewed to determine the company's financial condition or the presence of a catalyst that will trigger a price increase near- to mid-term.
Money market instruments primarily serve as “cover” for the Fund’s derivatives positions, although the subadviser also at times allocates assets to money market instruments in order to hedge against equity market risk. Money market instruments are high-quality short-term debt securities issued by governments and corporations. The Fund obtains exposure to U.S. Treasury bonds by purchasing futures contracts on U.S. Treasury bonds included in the Bloomberg U.S. Long Treasury Index. The Fund also may purchase options on U.S. Treasury bond futures contracts. The Fund uses U.S. Treasury bond futures and options to hedge against equity market risks. It is possible, however, that the Fund could lose money on both its equity investments and its bond exposures at the same time.
In determining what the subadviser believes to be the optimal allocation among equities, U.S. Treasury bonds and money market instruments, the subadviser uses estimates of future returns and volatility. When the subadviser believes that equity markets appear favorable, it uses leverage generated by futures and options to increase the Fund’s equity exposure. When equity markets appear to be unfavorable, the subadviser reduces the Fund’s equity exposure through the use of equity index futures and related options. It also may allocate assets to U.S. Treasury bond futures and related options and/or money market
12

Fund Summary: Nationwide BNY Mellon Disciplined Value Fund (cont.)
instruments. By combining equity securities, futures on stock indexes and U.S. Treasury bonds, call options and money market instruments in varying amounts, the subadviser adjusts the Fund’s overall equity exposure within a range of 80%–150% of the Fund’s net assets. “Equity exposure” for purposes of this range refers to exposure that may be broader than the definition of “equity securities” for purposes of the Fund's 80% policy, as described above. The subadviser regularly reviews the Fund's investments and will consider selling an investment when the subadviser believes such investment is no longer attractive as a result of price appreciation or a change in risk profile, or because other available investments are considered to be more attractive.
The Fund is designed for investors seeking total return consisting of capital appreciation and/or income, by investing in a portfolio of equity and debt securities, and derivatives with investment characteristics similar to equity and debt securities, in order to achieve enhanced equity returns while maintaining a level of volatility risk that is similar to the Russell 1000® Value Index.
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.
Leverage risk – leverage risk is a direct risk of investing in the Fund. Leverage is investment exposure that exceeds the initial amount invested. Derivatives and other transactions that give rise to leverage may cause the Fund’s performance to be more volatile than if the Fund had not been leveraged. Leveraging also may require that the Fund liquidate portfolio securities when it may not be advantageous to do so to satisfy its obligations. Certain derivatives provide the potential for investment gain or loss that may be several times greater than the change in the value of an underlying security, asset, interest rate, index or currency, resulting in the potential for a loss that may be substantially greater than the amount invested. Some leveraged investments have the potential for unlimited loss, regardless of the size of the initial investment.
Derivatives risk – derivatives may be volatile and may involve significant risks. The underlying security, measure or other instrument on which a derivative is based, or the derivative itself, may not perform as expected. Futures contracts and options on futures contracts typically involve
leverage, which means that their use can significantly magnify the effect of price movements of the underlying securities or reference measures, disproportionately increasing the Fund’s losses and reducing the Fund’s opportunities for gains. Some of these derivatives have the potential for unlimited loss, including a loss that may be greater than the amount invested. Certain futures contracts and related options may be illiquid, making it difficult to close out an unfavorable position. Finally, the Fund's use of derivatives may cause a Fund to realize higher amounts of short-term capital gains (generally taxed at ordinary income tax rates) than if the Fund had not used such instruments.
Futures – the prices of futures contracts typically are more volatile than those of stocks and bonds. Small movements in the values of the assets or measures of underlying futures contracts can cause disproportionately larger losses to the Fund. While futures may be more liquid than other types of derivatives, they may experience periods when they are less liquid than stocks, bonds or other investments.
Options – purchasing and selling options are highly specialized activities and entail greater-than-ordinary investment risks. The ability to close out positions in exchange-traded options depends on the existence of a liquid market. Options that expire unexercised have no value.
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 stock 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 and social unrest) 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.
Strategy risk – the subadviser’s strategy may cause the Fund to experience above-average short-term volatility. Accordingly, the Fund may be appropriate for investors who have a long investment time horizon and who seek long-term total return while accepting the possibility of significant short-term, or even long-term, 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
13

Fund Summary: Nationwide BNY Mellon Disciplined Value Fund (cont.)
other factors, such as changes in the exchange rates between the U.S. dollar and the currencies in which the securities are traded.
Value style risk – value investing carries the risk that the market will not recognize a security’s intrinsic value for a long time or that a stock judged to be undervalued actually is appropriately priced. In addition, value stocks as a group sometimes are out of favor and underperform the overall equity market for long periods while the market concentrates on other types of stocks, such as “growth” stocks.
Dividend-paying stock risk – there is no guarantee that the issuers of the stocks held by the Fund will declare dividends in the future or that, if dividends are declared, they will remain at their current levels or increase over time. The Fund’s emphasis on dividend-paying stocks could cause the Fund to underperform similar funds that invest without consideration of a company’s track record of paying dividends or ability to pay dividends in the future. Dividend-paying stocks may not participate in a broad market advance to the same degree as other stocks, and a sharp rise in interest rates or economic downturn could cause a company to unexpectedly reduce or eliminate its dividend.
Convertible securities risk - the values of convertible securities typically fall when interest rates rise and increase when interest rates fall. The prices of convertible securities with longer maturities tend to be more volatile than those with shorter maturities. Value also tends to change whenever the market value of the underlying common or preferred stock fluctuates. The Fund will lose money if the issuer of a convertible security is unable to meet its financial obligations.
Preferred stock risk – a preferred stock may decline in price, or fail to pay dividends when expected, because the issuer experiences a decline in its financial status. Preferred stocks often behave like debt securities, but have a lower payment priority than the issuer’s bonds or other debt securities. Therefore, they are subject to greater credit risk than those of debt securities. Preferred stocks also may be significantly less liquid than many other securities, such as corporate debt or common stock.
Initial public offering risk – availability of IPOs may be limited and the Fund may not be able to buy any shares at the offering price, or may not be able to buy as many shares at the offering price as it would like, which may adversely impact Fund performance. Further, IPO prices often are subject to greater and more unpredictable price changes than more established stocks.
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.
Fixed-income securities risk – investments in fixed-income securities, such as bonds, subject the Fund to interest rate risk, credit risk and prepayment and call risk, which may affect the value of your investment. Interest rate risk is the risk that the value of fixed-income securities will decline when interest rates rise. Prices of longer-term securities generally change more in response to interest rate changes than prices of shorter-term securities. To the extent the Fund invests a substantial portion of its assets in debt securities with longer-term maturities, rising interest rates are more likely to cause periods of increased volatility and redemptions, and may cause the value of the Fund’s investments to decline significantly. The Federal Reserve Board has begun to raise interest rates after a period of historic lows. The interest earned on the Fund's investments in fixed-income securities may decline when prevailing interest rates fall. Declines in interest rates increase the likelihood that debt obligations will be pre-paid, which, in turn, increases these risks. The Fund is subject to the risk that the income generated by its investments in fixed-income securities will not keep pace with inflation. Recent and potential future changes in government policy may affect interest rates.
Credit risk is the risk that the issuer of a bond may default if it is unable to pay interest or principal when due. If an issuer defaults, the Fund will lose money. Changes in a bond issuer’s credit rating or the market’s perceptions of an issuer’s creditworthiness also may affect the value of a bond. Prepayment and call risk is the risk that certain debt securities will be paid off by the issuer more quickly than anticipated. If this occurs, the Fund may be required to invest the proceeds in securities with lower yields.
Liquidity risk – when there is little or no active trading market for specific types of securities or instruments, it can become more difficult to sell the securities or instruments at or near their perceived value. An inability to sell a portfolio position can adversely affect the Fund's value or prevent the Fund from being able to take advantage of other investment opportunities. Liquidity risk also includes the risk that the Fund will experience significant net redemptions of its shares at a time when it cannot find willing buyers for its portfolio securities or instruments or can sell its portfolio securities or instruments only at a material loss. To meet redemption requests, the Fund may be forced to sell other securities or instruments that are more liquid, but at unfavorable times and conditions.
14

Fund Summary: Nationwide BNY Mellon Disciplined Value Fund (cont.)
Cash position risk – the Fund may hold significant positions in cash or money market instruments . A larger amount of such holdings could cause the Fund to miss investment opportunities presented during periods of rising market prices.
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.
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 Fund's performance prior to December 21, 2020 reflects returns pursuant to different principal investment strategies. If the Fund's current strategies had been in place during the prior period, the performance information shown would have been different.
The Fund has adopted the historical performance of the BNY Mellon Disciplined Stock Fund, a former series of BNY Mellon Investment Funds IV, Inc. (the “Predecessor Fund”) as the result of a reorganization in which the Fund acquired all of the assets, subject to liabilities, of the Predecessor Fund on December 16, 2019. The returns presented for periods prior to December 16, 2019 reflect the performance of the Predecessor Fund. At the time of the reorganization, the Fund and the Predecessor Fund had similar investment goals, although the Fund and the Predecessor Fund had different investment objectives. Further, while the Fund and the Predecessor Fund shared some investment strategies and policies, certain of the Fund's investment strategies and policies were different from those of the Predecessor Fund.
The following bar chart and table can help you evaluate the Fund’s potential risks. The bar chart shows how the Fund’s annual total returns have varied from year to year. These returns do not reflect the impact of sales charges. If sales charges were included, the annual total returns would be lower than those shown. The table compares the Fund’s average annual total returns to the returns of a broad-based securities index. Remember, however, that past performance (before and after taxes) is not necessarily indicative of how the Fund will perform in the future. Updated performance information is available at no cost by visiting nationwide.com/mutualfunds or by calling 800-848-0920. Sales charges are not reflected in the bar chart, and if those charges were included, returns would be less than those shown.

Nationwide Mutual Funds (the “Trust”) and Nationwide Fund Advisors (the “Adviser”) have entered into a written contract limiting annual fund operating expenses to 0.50% until at least February 29, 2024. Under the expense limitation agreement, the level to which operating expenses are limited applies to all share classes, excluding any taxes, interest, brokerage commissions, Rule 12b-1 fees, acquired fund fees and expenses, short-sale dividend expenses, administrative services fees, other expenses which are capitalized in accordance with generally accepted accounting principles and expenses incurred by the Fund in connection with any merger or reorganization, and may exclude other nonroutine expenses not incurred in the ordinary course of the Fund’s business. The expense limitation agreement may be changed or eliminated only with the consent of the Board of Trustees of the Trust. The Adviser may request and receive reimbursement from the Fund for advisory fees waived or other expenses reimbursed by the Adviser pursuant to the expense limitation agreement at a date not to exceed three years from the date in which the corresponding waiver or reimbursement to the Fund was made. However, no reimbursement may be made unless: (i) the Fund’s assets exceed $100 million and (ii) the total annual expense ratio of the class making such reimbursement is no higher than the amount of the expense limitation that was in place at the time the Adviser waived the fees or reimbursed the expenses and does not cause the expense ratio to exceed the current expense limitation. Reimbursement by the Fund of amounts previously waived or reimbursed by the Adviser is not permitted except as provided for in the expense limitation agreement.

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 2.29% of the average value of its portfolio.
Principal Investment Strategies
The Fund seeks to provide investors with long-term growth of capital by outperforming the S&P 500® Index over a full market cycle while maintaining a similar level of market risk as the index. To achieve this goal, the Fund’s subadviser seeks to identify and construct the most optimal portfolio that targets an equity-like level of volatility by allocating assets among equity securities, money market instruments, futures contracts the value of which are derived from the performance of equity indexes and U.S. Treasury bonds (which are government-issued fixed income securities), and options on equity index and bond futures contracts. Futures and options are derivatives and may expose the Fund to leverage. Investors in the Fund should have a long-term perspective and be able to tolerate potentially sharp declines in value.
Equity securities that the Fund buys primarily are common stocks of companies that are included in the S&P 500 Index. With respect to the Fund's portion that invests directly in equity securities, the Fund generally invests in all 500 stocks in the S&P 500 Index in proportion to their weightings in the index. Money market instruments serve primarily as cover for the Fund’s derivatives positions, although the
subadviser also at times allocates assets to money market instruments in order to hedge against equity market risk. Money market instruments are high-quality short-term debt securities issued by governments and corporations. The Fund obtains exposure to U.S. Treasury bonds by purchasing futures contracts on U.S. Treasury bonds included in the Bloomberg U.S. Long Treasury Index. The Fund also may purchase options on U.S. Treasury bond futures contracts. The Fund uses Treasury bond futures and options to hedge against equity market risks. It is possible, however, that the Fund will lose money on both its equity investments and its bond exposures at the same time. Under normal circumstances, the Fund invests at least 80% of its net assets in securities of U.S. issuers or derivatives the value of which are linked to securities of U.S. issuers.
In determining what the subadviser believes to be the optimal allocation among equities, U.S. Treasury bonds and money market instruments, the subadviser uses estimates of future returns and volatility. When the subadviser believes that equity markets appear favorable, it uses leverage generated by futures and options to increase the Fund’s equity exposure. When equity markets appear to be unfavorable, the subadviser reduces the Fund’s equity exposure through the use of equity index futures and related options. It also may allocate assets to U.S. Treasury bond futures and related options and/or money market instruments. By combining equity securities, futures on stock indexes and U.S. Treasury bonds, call options and money market instruments in varying amounts, the subadviser adjusts the Fund’s overall equity exposure within a range of 50%–150% of the Fund’s net assets. The subadviser regularly reviews the Fund's investments and will consider selling an investment when the subadviser believes such investment is no longer attractive as a result of price appreciation or a change in risk profile, or because other available investments are considered to be more attractive.
The Fund is designed for investors seeking growth of capital by investing in a portfolio of equity and debt securities, and derivatives with investment characteristics similar to equity and debt securities, in order to achieve enhanced equity returns while maintaining a level of volatility risk that is similar to the S&P 500 Index
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:
18

Fund Summary: Nationwide BNY Mellon Dynamic U.S. Core Fund (cont.)
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.
Leverage risk – leverage risk is a direct risk of investing in the Fund. Leverage is investment exposure that exceeds the initial amount invested. Derivatives and other transactions that give rise to leverage may cause the Fund’s performance to be more volatile than if the Fund had not been leveraged. Leveraging also may require that the Fund liquidate portfolio securities when it may not be advantageous to do so to satisfy its obligations. Certain derivatives provide the potential for investment gain or loss that may be several times greater than the change in the value of an underlying security, asset, interest rate, index or currency, resulting in the potential for a loss that may be substantially greater than the amount invested. Some leveraged investments have the potential for unlimited loss, regardless of the size of the initial investment.
Derivatives risk – derivatives may be volatile and may involve significant risks. The underlying security, measure or other instrument on which a derivative is based, or the derivative itself, may not perform as expected. Futures contracts and options on futures contracts typically involve leverage, which means that their use can significantly magnify the effect of price movements of the underlying securities or reference measures, disproportionately increasing the Fund’s losses and reducing the Fund’s opportunities for gains. Some of these derivatives have the potential for unlimited loss, including a loss that may be greater than the amount invested. Certain futures contracts and related options may be illiquid, making it difficult to close out an unfavorable position. Finally, the Fund's use of derivatives may cause a Fund to realize higher amounts of short-term capital gains (generally taxed at ordinary income tax rates) than if the Fund had not used such instruments.
Futures – the prices of futures contracts typically are more volatile than those of stocks and bonds. Small movements in the values of the assets or measures of underlying futures contracts can cause disproportionately larger losses to the Fund. While futures may be more liquid than other types of derivatives, they may experience periods when they are less liquid than stocks, bonds or other investments.
Options – purchasing and selling options are highly specialized activities and entail greater-than-ordinary investment risks. The ability to close out positions in exchange-traded options depends on the existence of a liquid market. Options that expire unexercised have no value.
Fixed-income securities risk – investments in fixed-income securities, such as bonds or other investments with debt-like characteristics (e.g., futures contracts the value of which are derived from the performance of bond indexes), subject the Fund to interest rate risk, credit risk and prepayment and call risk, which may affect the value of your investment. Interest rate risk is the risk that the value of fixed-income securities will decline when interest rates rise. Prices of longer-term securities generally change more in response to interest rate changes than prices of shorter-term securities. To the extent the Fund invests a substantial portion of its assets in debt securities with longer-term maturities, rising interest rates are more likely to cause periods of increased volatility and redemptions, and may cause the value of the Fund’s investments to decline significantly. The Federal Reserve Board has begun to raise interest rates after a period of historic lows. The interest earned on the Fund's investments in fixed-income securities may decline when prevailing interest rates fall. Declines in interest rates increase the likelihood that debt obligations will be pre-paid, which, in turn, increases these risks. The Fund is subject to the risk that the income generated by its investments in fixed-income securities will not keep pace with inflation. Recent and potential future changes in government policy may affect interest rates.
Credit risk is the risk that the issuer of a bond may default if it is unable to pay interest or principal when due. If an issuer defaults, the Fund will lose money. Changes in a bond issuer’s credit rating or the market’s perceptions of an issuer’s creditworthiness also may affect the value of a bond. Prepayment and call risk is the risk that certain debt securities will be paid off by the issuer more quickly than anticipated. If this occurs, the Fund may be required to invest the proceeds in securities with lower yields.
Cash position risk – the Fund may hold significant positions in cash or money market instruments . A larger amount of such holdings could cause the Fund to miss investment opportunities presented during periods of rising market prices.
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 stock 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 and social unrest) adversely interrupt the global economy.
19

Fund Summary: Nationwide BNY Mellon Dynamic U.S. Core Fund (cont.)
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.
Strategy risk – the subadviser’s strategy may cause the Fund to experience above-average short-term volatility. Accordingly, the Fund may be appropriate for investors who have a long investment time horizon and who seek long-term capital growth while accepting the possibility of significant short-term, or even long-term, losses.
Index strategy risk – the portion of the Fund that invests directly in equity securities does not use defensive strategies or attempt to reduce its exposure to poor performing securities. Further, correlation between such portion’s performance and that of the index is likely to be negatively affected by the Fund’s expenses, changes in the composition of the index, and the timing of purchase and redemption of Fund shares.
Liquidity risk – when there is little or no active trading market for specific types of securities or instruments, it can become more difficult to sell the securities or instruments at or near their perceived value. An inability to sell a portfolio position can adversely affect the Fund's value or prevent the Fund from being able to take advantage of other investment opportunities. Liquidity risk also includes the risk that the Fund will experience significant net redemptions of its shares at a time when it cannot find willing buyers for its portfolio securities or instruments or can sell its portfolio securities or instruments only at a material loss. To meet redemption requests, the Fund may be forced to sell other securities or instruments that are more liquid, but at unfavorable times and conditions.
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.

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 53.21% of the average value of its portfolio.
Principal Investment Strategies
The Fund invests in a diversified portfolio of common stocks to produce an overall blended equity portfolio consisting of various types of stocks that the subadviser believes offer the potential for capital growth and/or dividend income. Most of the stocks in which the Fund invests are issued by large-capitalization companies. The Fund considers large-capitalization companies to be those companies with market capitalizations of more than $5 billion. Some of these companies may be located outside of the United States. The Fund makes market capitalization determinations with respect to a security at the time it purchases such security.
In managing the Fund, the subadviser allocates the Fund’s assets across a variety of industries, selecting companies in each industry based on the research of a team of global industry analysts. The Fund typically seeks to maintain representation in each major industry represented by broad-based, large-cap U.S. equity indices.
The subadviser employs a “bottom-up” approach to selecting securities, emphasizing those that it believes to represent above-average potential for total return, based on fundamental research and analysis. Fundamental analysis of a company typically involves the assessment of a variety of factors, and may include the company’s business environment, management quality, balance sheet, income statement, anticipated earnings, revenues and dividends, and environmental, social and/or governance (ESG) factors. The subadviser seeks to develop a portfolio that is broadly diversified across issuers, sectors, industries and styles. The Fund’s portfolio therefore will include stocks that are considered to be either growth stocks or value stocks. Because the subadviser’s process is driven primarily by individual stock selection, the overall portfolio’s yield, price-to-earnings ratio, price-to-book ratio, growth rate and other
characteristics will vary over time and, at any given time, the Fund may emphasize either growth stocks or value stocks. The subadviser may sell a security when it believes that a significant change in the company’s business fundamentals exists, it has become overvalued in terms of earnings, assets or growth prospects, or in order to take advantage of more attractive alternatives.
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 stock 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 and social unrest) 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.
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.
Dividend-paying stock risk – there is no guarantee that the issuers of the stocks held by the Fund will declare dividends in the future or that, if dividends are declared, they will remain at their current levels or increase over time.
Growth style risk – growth stocks are generally more sensitive to market movements than other types of stocks primarily because their stock prices are based heavily on future expectations. If the subadviser’s assessment of the prospects for a company’s growth is wrong, or if the subadviser’s judgment of how other investors will value the company’s growth is wrong, then the Fund will suffer a loss
23

Fund Summary: Nationwide Fund (cont.)
as the price of the company’s stock may fall or not approach the value that the subadviser has placed on it. In addition, growth stocks as a group sometimes are out of favor and underperform the overall equity market for long periods while the market concentrates on other types of stocks, such as “value” stocks.
Value style risk – value investing carries the risk that the market will not recognize a security’s intrinsic value for a long time or that a stock judged to be undervalued actually is appropriately priced. In addition, value stocks as a group sometimes are out of favor and underperform the overall equity market for long periods while the market concentrates on other types of stocks, such as “growth” stocks.
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.

Tax Information
The Fund’s distributions are taxable, and generally will be taxed as ordinary income, capital gains, or some combination of both, unless you are investing through a tax-advantaged arrangement, such as a 401(k) plan or an individual retirement account, in which case your distributions may be taxed as ordinary income when withdrawn from the tax-advantaged account.
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 salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.

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 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:

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
26

Fund Summary: Nationwide Geneva Mid Cap Growth Fund (cont.)
the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 10.71% of the average value of its portfolio.
Principal Investment Strategies
The Fund invests, under normal market conditions, in common stocks of publicly traded companies that the subadviser believes demonstrate, at the time of a stock’s purchase, strong growth characteristics such as a leadership position in the relevant industry, a sustainable advantage, strong earnings growth potential and experienced management.
The Fund’s investment focus is on U.S. companies whose market capitalization is generally within the market capitalization range of the companies represented in the Russell Midcap® Growth Index at time of purchase (“mid-cap growth companies”), although the Fund may invest in companies outside this range. Under normal circumstances, the Fund invests at least 80% of its net assets in mid-cap growth companies. The Fund makes market capitalization determinations with respect to a security at the time of purchase of such security. Because the Fund may continue to hold a security whose market capitalization increases or decreases, a substantial portion of the Fund’s holdings can have market capitalizations outside the range of the Russell Midcap® Growth Index at any given time. In selecting growth stocks for the Fund, the subadviser emphasizes a “bottom-up” fundamental analysis (i.e., developing an understanding of the specific company through research, meetings with management and analysis of the company’s financial statements and public disclosures). The subadviser’s “bottom-up” approach is supplemented by “top-down” considerations (i.e., reviewing general economic conditions and analyzing their effect on various industries). At times the subadviser emphasizes one or more industries or sectors.
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 stock 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 and social unrest) 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.
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.
Growth style risk – growth stocks are generally more sensitive to market movements than other types of stocks primarily because their stock prices are based heavily on future expectations. If the subadviser’s assessment of the prospects for a company’s growth is wrong, or if the subadviser’s judgment of how other investors will value the company’s growth is wrong, then the Fund will suffer a loss as the price of the company’s stock may fall or not approach the value that the subadviser has placed on it. In addition, growth stocks as a group sometimes are out of favor and underperform the overall equity market for long periods while the market concentrates on other types of stocks, such as “value” stocks.
Mid-cap risk – medium-sized companies are usually less stable in price and less liquid than larger, more established companies. Therefore, they generally involve greater risk.
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 Fund has adopted the historical performance of the HighMark Geneva Mid Cap Growth Fund, a former series of HighMark Funds (the “Predecessor Fund”) as the result of a reorganization in which the Fund acquired all of the assets, subject to the liabilities, of the Predecessor Fund on September 16, 2013. The returns presented for periods prior to September 16, 2013 reflect the performance of the Predecessor Fund. At the time of the reorganization, the Fund and the Predecessor Fund had substantially similar investment goals and strategies.

Fund Summary: Nationwide Geneva Mid Cap Growth Fund (cont.)
The following bar chart and table can help you evaluate the Fund’s potential risks. The bar chart shows how the Fund’s annual total returns have varied from year to year. The table compares the Fund’s average annual total returns to the returns of a broad-based securities index. Remember, however, that past performance (before and after taxes) is not necessarily indicative of how the Fund will perform in the future. Updated performance information is available at no cost by visiting nationwide.com/mutualfunds or by calling 800-848-0920.
Sales charges are not reflected in the bar chart, and if those charges were included, returns would be less than those shown.

(Years Ended December 31,)
Highest Quarter:

2Q 2020
Lowest Quarter:

2Q 2022
After-tax returns are shown for Class A shares only and will vary for other classes. After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect state and local taxes. Your actual after-tax return depends on your personal tax situation and may differ from what is shown here. After-tax returns are not relevant to investors in tax-advantaged arrangements, such as individual retirement accounts, 401(k) plans or certain other employer-sponsored retirement plans.
Historical performance for Class A, Class C and Institutional Service Class shares is based on the previous performance of Class A, Class C and Fiduciary Class Shares, respectively, of the Predecessor Fund.
The inception date for Class R6 shares is September 18, 2013. Therefore, pre-inception historical performance of Class R6 shares is based on the previous performance of the Predecessor Fund’s Fiduciary Class Shares. Performance for Class R6 shares has not been adjusted to reflect that share class’s lower expenses than those of the Predecessor Fund’s Fiduciary Class Shares.
