Fund Summary Information

Federated Hermes International Growth Fund (the “Fund”)

RISK/RETURN SUMMARY: INVESTMENT OBJECTIVE

The Fund’s investment objective seeks to provide long-term capital appreciation. The objective may be changed by the Fund’s Board of Trustees (the “Trustees”) without shareholder approval.

Management Fee	0.75%	0.75%
Distribution (12b-1) Fee	0.00%1	0.75%
Other Expenses2	0.70%	0.70%

Fee Waivers and/or Expense Reimbursements3	(0.35)%	(0.35)%
Total Annual Fund Operating Expenses After Fee Waivers and/or Expense Reimbursements	1.10%	1.85%

The Fund has adopted a Distribution (12b-1) Plan for its Class A Shares pursuant to which the A class

of the Fund may incur and pay a Distribution (12b-1) Fee of up to a maximum of 0.05%. No such fee

is currently incurred and paid by the A class of the Fund. The A class of the Fund will not incur and

pay such a Distribution (12b-1) Fee until such time as approved by the Trustees.

Other Expenses are based on estimated amounts for the current fiscal year.

The Adviser and certain of its affiliates on their own initiative have agreed to waive certain amounts

of their respective fees and/or reimburse expenses. Effective August 1, 2026, total annual fund

operating expenses (excluding acquired fund fees and expenses, tax reclaim recovery expenses,

interest expense, extraordinary expenses and proxy-related expenses, if any) paid by the Fund’s A

and C classes (after the voluntary waivers and/or reimbursements) will not exceed 1.10% and 1.85%

(the “Fee Limit”), respectively, up to but not including the later of (the “Termination Date”):

(a) August 1, 2027; or (b) the date of the Fund’s next effective Prospectus. While the Adviser and its

affiliates currently do not anticipate terminating or increasing these arrangements prior to the

Termination Date, these arrangements may only be terminated or the Fee Limit increased prior to the

Termination Date with the approval of the Trustees.

Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds.

The Example assumes that you invest $10,000 for the time periods indicated and then redeem all of your Shares at the end of those periods. Expenses assuming no redemption are also shown. The Example also assumes that your investment has a 5% return each year and that operating expenses remain the same. The Example does not reflect sales charges (loads) on reinvested dividends. If these sales charges (loads) were included, your costs would be higher. Although your actual costs and returns may be higher or lower, based on these assumptions your costs would be:

Share Class	1 Year	3 Years	5 Years	10 Years
A:
Expenses assuming redemption	$689	$983	$1,299	$2,190
Expenses assuming no redemption	$689	$983	$1,299	$2,190
C:
Expenses assuming redemption	$323	$688	$1,180	$2,344
Expenses assuming no redemption	$223	$688	$1,180	$2,344

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 30% of the average value of its portfolio.

RISK/RETURN SUMMARY: INVESTMENTS, RISKS and PERFORMANCE

What are the Fund’s Main Investment Strategies?

The Fund pursues its investment objective to provide long-term capital appreciation by investing primarily in a portfolio of equity securities that are tied economically to a number of countries throughout the world and typically invests in three or more countries outside of the United States (U.S.). The Fund has broad discretion to invest in equity securities of any market capitalization and issuers located or doing business throughout the world, including in both developed and developing or emerging markets. However, the Fund principally invests in companies with a market capitalization in excess of $500 million, and the Fund does not expect to make additional investments in developing or emerging markets if it would cause the Fund to have a greater than 10% overweight position to developing or emerging markets as compared to the exposure of the MSCI ACWI ex Growth USA Index to such markets. The Fund may make significant investments (e.g., more than 25% of the Fund’s portfolio) in issuers located or doing business in a single country.

The Fund’s investments in equity securities may include, for example, common stocks, American Depositary Receipts or other U.S. listings of foreign common stocks. The Fund may use closed-end funds and derivative instruments to gain broad exposure to markets and/or a particular index. Derivative instruments include, but are not limited to, financial futures, as well as currency futures and currency forward contracts. For example, the Fund may use derivative contracts to increase or decrease the portfolio’s exposure to the investment(s) underlying the derivative instruments in an attempt to benefit from changes in the value of the underlying investment(s), to obtain premiums from the sale of derivative contracts, to realize gains from trading a derivative contract or to hedge against potential losses. There can be no assurance that the Fund’s use of derivatives contracts will work as intended.

Federated Global Investment Management Corp.’s (the “Adviser”) investment process seeks to identify companies with robust and sustainable growth rates, high-quality balance sheets, and management teams with clearly defined growth strategies. In allocating the Fund’s assets, the Adviser also incorporates information on the economic and financial market conditions within each country. The Adviser’s proprietary quantitative model drives country allocation, while individual stocks are selected through a qualitative process that incorporates a multi-factor approach to find companies with sustainable growth characteristics. The Adviser seeks to control risk by seeking diversification across sectors and using both fundamental and statistical models to evaluate potential volatility. The Adviser’s portfolio construction process seeks to combine the best investment candidates within the Adviser’s recommended framework of country allocations.

The Fund utilizes an active trading approach. The Adviser may choose to sell a holding when, for example, in the Adviser’s view, it no longer represents an attractive investment or to take advantage of what it considers to be a better investment opportunity.

Under normal circumstances, the Fund will invest its assets so that at least 80% of its net assets (plus any borrowings for investment purposes) are invested in growth investments. Growth investments are defined as securities that are either within the MSCI ACWI ex USA Growth Index or with earnings growth characteristics within the range of companies in the MSCI ACWI ex USA Growth Index.

What are the Main Risks of Investing in the Fund?

All mutual funds take investment risks. Therefore, it is possible to lose money by investing in the Fund. The primary factors that may reduce the Fund’s returns include:

■ Stock Market Risk. The value of equity securities in the Fund’s portfolio will fluctuate and, as a result, the Fund’s Share price may decline suddenly or over a sustained period of time. Declines in value can occur because of events relating to an issuer of a particular security resulting in a decline in the price of a particular portfolio holding, shareholder redemptions, or events relating to the broader stock market or economy, including changes in interest rates, industry or economic trends, monetary policy changes, market volatility and liquidity, or other adverse effects, which could negatively impact the Fund’s performance. Information publicly available about an issuer, whether from the issuer’s financial statements or other disclosures or from third parties, or information available to some but not all market participants, also can affect the price of an issuer’s shares in the market. The Adviser and its affiliated investment advisers, as well as third party advisers, also may manage other funds and accounts that use similar investment strategies, and invest in similar securities, as the Fund, and investments in certain securities by multiple funds and accounts, including those managed by the Adviser and its affiliates, could impact the availability of suitable securities and cause a capacity constraint associated with the Fund’s investment strategy and could cause the Fund to be closed entirely or partially to new investment by all or certain shareholders.

■ Small-Cap Company Risk. The Fund may invest in small capitalization (or “small-cap”) companies. Small-cap companies may have less liquid stock, a more volatile share price, unproven track records, a limited product or service base, and limited access to capital. The above factors could make small-cap companies more likely to fail than larger companies, and increase the volatility of the Fund’s portfolio, performance and Share price.

■ Mid-Cap Company Risk. The Fund may invest in mid-capitalization (or “mid-cap”) companies. Mid-cap companies often have narrower markets, limited managerial and financial resources, more volatile performance and greater risk of failure, compared to larger, more established companies. These factors could increase the volatility of the Fund’s portfolio, performance and Share price.

■ Focused Investment Risk. To the extent that the Fund focuses its investments in the securities of a particular issuer or companies in a particular country, group of countries, region, market, industry, group of

industries, sector, or asset class, the Fund’s exposure to various risks may be heightened, including price volatility and adverse economic, market, political, or regulatory occurrences affecting that issuer, country, group of countries, region, market, industry, group of industries, sector, or asset class.

■ Large Shareholder Risk. A significant percentage of the Fund’s shares may be owned or controlled by a large shareholder, such as other funds or accounts, including those of which the Adviser or an affiliate of the Adviser may have investment discretion. Accordingly, the Fund can be subject to the potential for large scale inflows and outflows as a result of purchases and redemptions made by significant shareholders. These inflows and outflows could be significant and, if frequently occurring, could negatively affect the Fund’s net asset value and performance and could cause the Fund to buy or sell securities at inopportune times in order to meet purchase or redemption requests. Investments in the Fund by other investment companies also can create conflicts of interests for the Adviser to the Fund and the investment adviser to the acquiring fund. For example, a conflict of interest can arise due to the possibility that the investment adviser to the acquiring fund could make a decision to redeem the acquiring fund’s investment in the Fund. In the case of an investment by an affiliated fund, a conflict of interest can arise if, because of the acquiring fund’s investment in the Fund, the Fund is able to garner more assets from third-party investors, thereby growing the Fund and increasing the management fees received by the Adviser, which could also be the investment adviser to the acquiring fund.

■ Risk Related to the Economy. The value of the Fund’s portfolio may decline in tandem with a drop in the overall value of the markets in which the Fund invests and/or other markets. Global economic, political and financial conditions, including geopolitical and other events (e.g., wars, tensions, sanctions and terrorism), legislative changes or shifts in fiscal or monetary policy or reform, industry or economic trends and developments, grid congestion or capacity constraints, natural disasters or public health risks, such as epidemics or pandemics, may, from time to time, and for varying periods of time, have a significant effect on the economies of many nations, including the U.S., and financial markets generally and cause the Fund to experience volatility, illiquidity, loss of value, shareholder redemptions, and/or other potentially adverse effects.

■ Greater China Risk. Although larger and/or more established than many emerging markets, the markets of the Greater China region function in many ways as emerging markets, and carry the high levels of risks associated with emerging markets. Investments in the Greater China region may be subject to the risks associated with trading on less-developed trading markets, in addition to risks associated with the Chinese government’s substantial control over the Chinese economy and possible negative repercussions from such authority, acute political risks resulting from China’s relationship with Taiwan or Hong Kong, restrictions on monetary repatriation, and/or other adverse government actions, which could likely have a significant adverse

impact on the value and liquidity of the Fund’s investments in the Greater China region. As export-driven economies, the economies of countries in the Greater China region are affected by developments in the economies of and relations with their principal trading partners. The implementation of more stringent tariffs or trade restrictions on Chinese exports by the U.S. government or other foreign governments, or even the threat of these actions, could have a negative impact on the Chinese economy and the Fund’s investments. In addition, the risk of sanctions or restrictions on certain Chinese issuers and their securities by the U.S. government or other governments may impact investments in such securities, and the Fund may be forced to sell such restricted securities and incur a loss as a result.

■ Risk of Foreign Investing. The foreign markets in which the Fund invests may be subject to economic or political conditions which are less favorable than those of the United States and may lack financial reporting standards or regulatory requirements comparable to those applicable to U.S. companies.

■ Risk of Investing in Depositary Receipts and Domestically Traded Securities of Foreign Issuers. Because the Fund may invest in American Depositary Receipts and other domestically traded securities of foreign companies, whether in the United States or in foreign local markets, the Fund’s Share price may be more affected by foreign economic and political conditions, taxation policies and accounting and auditing standards than would otherwise be the case.

■ Currency Risk. Exchange rates for currencies fluctuate daily. Accordingly, the Fund may experience increased volatility with respect to the value of its Shares and its returns as a result of its exposure to foreign currencies through direct holdings of such currencies or holdings of non-U.S. dollar-denominated securities.

■ European Union and Eurozone Related Risk. A number of countries in the European Union (EU), including certain countries within the EU that have adopted the euro (Eurozone), have experienced, and may continue to experience, severe economic and financial difficulties. Additional countries within the EU may also fall subject to such difficulties. These events could negatively affect the value and liquidity of the Fund’s investments in euro-denominated securities and derivatives contracts, securities of issuers located in the EU or with significant exposure to EU issuers or countries.

■ Risk of Investing in Emerging Market Countries. Securities issued or traded in emerging markets generally entail greater risks than securities issued or traded in developed markets. Securities markets within emerging market countries may experience low or non-existent trading volume, resulting in a lack of liquidity and increased volatility in prices for such securities. Political and economic structures in emerging market countries generally lack the social, political and economic stability of developed countries, which may affect the value of the Fund’s investments in these countries. There may be less publicly available information about issuers in emerging markets than would be available about issuers in more developed

capital markets, and such issuers may not be subject to accounting, auditing, and financial reporting standards comparable to those to which U.S. companies are subject.

■ Risk Related to Investing for Growth. Due to their relatively high valuations, growth stocks are typically more volatile than value stocks. For instance, the price of a growth stock may experience a larger decline on a forecast of lower earnings, a negative fundamental development, or an adverse market development. Further, growth stocks may not pay dividends or may pay lower dividends than value stocks. This means they depend more on price changes for returns and may be more adversely affected in a down market compared to value stocks that pay higher dividends.

■ Liquidity Risk. The securities in which the Fund invests may be less readily marketable and may be subject to greater fluctuation in price than other securities.

■ Interest Rate Risk. Prices of fixed-income securities generally fall when interest rates rise. The longer the duration of a fixed-income security, the more susceptible it is to interest rate risk. Recent and potential future changes in monetary policy made by central banks and/or their governments are likely to affect the level of interest rates.

■ Custodial Services and Related Investment Costs. Custodial services and other costs relating to investment in international securities markets generally are more expensive due to differing settlement and clearance procedures than those of the United States.

■ Risk of Investing in Derivative Contracts. Derivative contracts involve risks different from, or possibly greater than, risks associated with investing directly in securities and other traditional investments. Specific risk issues related to the use of such contracts include valuation and tax issues, increased potential for losses and/or costs to the Fund and a potential reduction in gains to the Fund. Each of these issues is described in greater detail in this Prospectus. Derivative contracts may also involve other risks described in this Prospectus, such as stock market, interest rate, credit, currency and liquidity risks.

■ Issuer Credit Risk. It is possible that interest or principal on securities will not be paid when due. Such non-payment or default may reduce the value of the Fund’s portfolio holdings, its share price and its performance.

■ Counterparty Risk. Counterparty risk includes the possibility that a party to a transaction involving the Fund will fail to meet its obligations. This could cause the Fund to lose money or to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategy.

■ Quantitative Modeling Risk. The Fund employs quantitative models as a management technique. These models examine multiple economic factors using various proprietary and third-party data. The results generated by quantitative analysis may perform differently than expected and may

negatively affect Fund performance for various reasons (for example, human judgment, data imprecision, software or other technology malfunctions, or programming inaccuracies).

■ Exchange-Traded Funds Risk. An investment in an ETF generally presents the same primary risks as an investment in a conventional fund (i.e., one that is not exchange traded) that has the same investment objectives, strategies and policies. The price of an ETF can fluctuate up or down, and the Fund could lose money investing in an ETF if the prices of the securities owned by the ETF go down.

■ Technology Risk. The Adviser uses various technologies in managing the Fund consistent with its investment objective and strategy described in this Prospectus. For example, proprietary and third-party data and systems are utilized to support decision making for the Fund. Data imprecision, software or other technology malfunctions, programming inaccuracies and similar circumstances may impair the performance of these systems, which may negatively affect Fund performance.

Shares offered by this Prospectus are not deposits or obligations of any bank, are not endorsed or guaranteed by any bank and are not insured or guaranteed by the U.S. government, the Federal Deposit Insurance Corporation, the Federal Reserve Board or any other government agency.

Performance: Bar Chart and Table

Risk/Return Bar Chart

The Fund is the legal entity successor to the PNC International Growth Fund (“Predecessor Fund”), a portfolio of PNC Funds, pursuant to a tax-free reorganization that took place on November 15, 2019. Pursuant to the reorganization, the Fund is the legal entity survivor and the Predecessor Fund is the accounting and tax survivor of the reorganization. Accordingly, the performance information, including information on fees and expenses and financial information provided in this prospectus for periods prior to the reorganization (the Fund’s commencement of investment operations) is historical information for the Predecessor Fund. The Predecessor Fund was managed by the same portfolio management team as the Fund, had an identical investment objective and substantially identical strategies, policies, and restrictions. Given the above, unless specifically stated otherwise, subsequent references in this section to the Fund should be read to include the Predecessor Fund.

The Fund’s A and C classes have not yet commenced operations. The Fund currently offers two other classes of shares: Institutional Shares (“IS class”) and Class R6 Shares. For periods prior to the reorganization (the Fund’s commencement of investment operations), the performance of the Fund’s IS class is the historical performance of the Predecessor Fund’s I class. For the periods prior to the commencement of operations of the A and C classes, the performance information shown below is for the Fund’s IS class. The performance of the IS class has not been adjusted to reflect the expenses

applicable to the A or C class. The performance has been adjusted to reflect the differences in sale charges and deferred sales charges applicable to A class and C class. The A, C and IS classes are invested in the same portfolio of securities and the annual returns will differ only to the extent that the classes do not have the same expenses or sales loads. It is anticipated that the expense ratios of the A and C classes will be higher than the expense ratio of the IS class; accordingly, the actual performance of the A and C classes is anticipated to be lower than the performance of the IS class.

The bar chart and performance table below are intended to help you analyze the Fund’s investment risks in light of its historical returns. The bar chart shows the variability of the Fund’s IS class total returns on a calendar year-by-year basis. The Average Annual Total Return table shows returns averaged over the stated periods, and includes comparative performance information with a broad-based securities market index. The Fund’s performance is also compared to a secondary index to show how the Fund’s performance compares with the returns of an index with similar investments. The Fund’s performance will fluctuate, and past performance (before and after taxes) is not necessarily an indication of future results. Updated performance information for the Fund is available under the “Products” section at FederatedHermes.com/us or by calling 1-800-341-7400.

The Fund’s IS class total return for the six-month period from January 1, 2026 to June 30, 2026, was 17.18%.

Within the periods shown in the bar chart, the Fund’s IS class highest quarterly return was 31.97% (quarter ended June 30, 2020). Its lowest quarterly return was (18.97)% (quarter ended March 31, 2020).

Average Annual Total Return Table

The Fund’s A and C classes have not yet commenced operations. The A and C class performance information shown below is for the Fund’s IS class as described above. In addition to Return Before Taxes, Return After Taxes is shown for the Funds A class to illustrate the effect of federal taxes on Fund returns. After-tax returns are shown only for A class, and after-tax returns for the C class will differ from those shown for A class. Actual after-tax returns depend on each investor’s personal tax situation, and are likely to differ from those shown. After-tax returns are calculated using a standard set of assumptions. The stated returns assume the highest historical federal income and capital gains tax rates. These after-tax returns do not reflect the effect of any applicable state and local taxes. After-tax returns are not relevant to investors holding Shares through a 401(k) plan, an Individual Retirement Account (IRA) or other tax-advantaged investment plans.
