Fund Summary Information

Federated Hermes Intermediate Corporate Bond Fund (the "Fund")

RISK/RETURN SUMMARY: INVESTMENT OBJECTIVE

The Fund's investment objective is to provide current income.

RISK/RETURN SUMMARY: FEES AND EXPENSES

This table describes the fees and expenses that you may pay if you buy, hold and sell the Fund's Institutional Shares (IS), Service Shares (SS) and Class R6 Shares (R6). You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the tables and examples below.

	IS	SS	R6
Management Fee	0.44%	0.44%	0.44%
Distribution (12b-1) Fee	None	0.25%	None
Other Expenses	0.52%	0.50%	0.18%
Total Annual Fund Operating Expenses	0.96%	1.19%	0.62%

Total Annual Fund Operating Expenses After Fee Waivers and/or Expense Reimbursements	0.52%	0.77%	0.46%

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 or hold all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that 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
IS	$98	$306	$531	$1,178
SS	$121	$378	$654	$1,443
R6	$63	$199	$346	$774

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 27% of the average value of its portfolio.

RISK/RETURN SUMMARY: INVESTMENTS, RISKS and PERFORMANCE

What are the Fund's Main Investment Strategies?

The Fund invests in a diversified portfolio of investment-grade, fixed-income securities consisting primarily of corporate debt securities, U.S. government mortgage-backed securities, and U.S. Treasury and agency securities. The Fund's investment adviser (the "Adviser") seeks to enhance the Fund's performance by allocating relatively more of its portfolio to the security type that the Adviser expects to offer the best balance between current income and risk. Some of the corporate debt securities in which the Fund invests are considered to be "foreign securities," which are securities of issuers based outside of the United States. The foreign securities in which the Fund invests will be predominately denominated in U.S. dollars. Investment-grade securities are rated in one of the four highest categories (BBB or higher) by a nationally recognized statistical rating organization (NRSRO), or if unrated, of comparable quality as determined by the Adviser. The Fund may invest in derivative contracts (such as, for example, futures contracts) and/or hybrid instruments to implement elements of its investment strategy. For example, the Fund may use derivative contracts or hybrid instruments to increase or decrease the portfolio's exposure to the investment(s) underlying the derivative contract or hybrid instrument in an attempt to benefit from changes in the value of the underlying investment(s). There can be no assurance that the Fund's use of derivative contracts or hybrid instruments will work as intended. Derivative

investments made by the Fund are included within the Fund's 80% policy (as described below) and are calculated at market value. Consistent with the Fund's benchmark, the Fund may, from time to time, have larger allocations to certain broad market sectors in attempting to achieve its investment objective.

The Fund intends to invest in the securities of U.S. government-sponsored entities (GSEs), including GSE securities that are not backed by the full faith and credit of the U.S. government, such as those issued by the Federal Home Loan Mortgage Corporation, the Federal National Mortgage Association and the Federal Home Loan Bank System. These entities are, however, supported through federal subsidies, loans or other benefits. The Fund may also invest in GSE securities that are supported by the full faith and credit of the U.S. government, such as those issued by the Government National Mortgage Association. Finally, to a lesser extent, the Fund may invest in certain GSE securities that have no explicit financial support, but which are regarded as having implied support because the federal government sponsors their activities.

Although the value of the Fund's Shares will fluctuate, the Adviser will seek to manage the magnitude of fluctuation by limiting, under normal market conditions, the Fund's dollar-weighted average maturity to between three and ten years and dollar-weighted average duration to between three and seven years. Maturity reflects the time until a fixed-income security becomes payable. Duration measures the price sensitivity of a fixed-income security to changes in interest rates.

The Fund will invest its assets so that at least 80% of its net assets (plus any borrowings for investment purposes) are invested in corporate fixed-income investments. The Fund will notify shareholders at least 60 days in advance of any change in this investment policy.

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:

■ 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.

■ 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.

■ Liquidity Risk. The fixed-income securities in which the Fund invests may be less readily marketable and may be subject to greater fluctuation in price than other securities. Liquidity risk also refers to the possibility that the Fund may not be able to sell a security or close out a derivative contract when it wants to. If this happens, the Fund could incur losses.

■ Risk of Foreign Investing. Because the Fund invests in securities issued by foreign companies and national governments, 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.

■ Call Risk. The Fund's performance may be adversely affected by the possibility that an issuer of a security held by the Fund may redeem the security prior to maturity at a price below its current market value.

■ Prepayment and Extension Risk. When homeowners prepay their mortgages in response to lower interest rates, the Fund will be required to reinvest the proceeds at the lower interest rates available. Also, when interest rates fall, the price of mortgage-backed securities may not rise to as great an extent as that of other fixed-income securities. When interest rates rise, homeowners are less likely to prepay their mortgages. A decreased rate of prepayments lengthens the expected maturity of a mortgage-backed security, and the price of mortgage-backed securities may decrease more than the price of other fixed-income securities.

■ Leverage Risk. Leverage risk is created when an investment exposes the Fund to a level of risk that exceeds the amount invested. Changes in the value of such an investment magnify the Fund's risk of loss and potential for gain.

■ Risk of Investing in Derivative Contracts and Hybrid Instruments. Derivative contracts and hybrid instruments 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 and instruments 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 and hybrid instruments may also involve other risks described in this Prospectus, such as interest rate, credit, liquidity and leverage risks.

■ 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.

■ Mortgage-Backed Securities (MBS) Risk. A rise in interest rates may cause the value of MBS held by the Fund to decline. Certain MBS issued by GSEs are not backed by the full faith and credit of the U.S. government. A non-agency MBS is subject to the risk that the value of such security will decline, because the security is not issued or guaranteed as to principal or interest by the U.S. government or a GSE. These securities may have exposure to borrowers with weakened credit histories, increasing the potential for default (subprime risk). The Fund's investments in collateralized mortgage obligations (CMOs) may entail greater market, prepayment and liquidity risks than other MBS. The liquidity of non-agency MBS and CMOs may also vary dramatically over time.

■ Sector Risk. Because the Fund may allocate relatively more assets to certain industry sectors than others, the Fund's performance may be more susceptible to any developments which affect those sectors emphasized by the Fund.

■ Technology Risk. The Adviser uses various technologies in managing the Fund, consistent with its investment objective(s) 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.

The 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 bar chart and performance table below reflect historical performance data for the Fund and 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 for each class 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 three-month period from January 1, 2026 to March 31, 2026, was (0.21)%.

Within the periods shown in the bar chart, the Fund's IS class highest quarterly return was 7.85% (quarter ended June 30, 2020). Its lowest quarterly return was (5.05)% (quarter ended March 31, 2022).

Average Annual Total Return Table

The Fund's R6 class commenced operations on July 1, 2024. For the periods prior to the commencement of operations of the R6 class, the R6 class performance information shown below is for the Fund's IS class. The performance of the Fund's IS class has not been adjusted to reflect the expenses applicable to the R6 class since the R6 class has a lower expense ratio than the expense ratio of the IS class. The Fund's R6 class would have annual returns substantially similar to those of the IS class because the shares are invested in the same portfolio of securities and the annual returns would differ only to the extent that the classes do not have the same expenses. In addition to Return Before Taxes, Return After Taxes is shown for the Fund's IS class to illustrate the effect of federal taxes on Fund returns. After-tax returns are shown only for the IS class, and after-tax returns for the SS and R6 classes will differ from those shown for the IS 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 or other tax-advantaged investment plan.
