Total Annual Fund Operating Expenses After Fee Waivers and/or Expense Reimbursements	1.33%	0.60%	0.83%

The Fund has adopted a Distribution (12b-1) Plan for its SS class pursuant to which the SS 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 SS class of the Fund. The SS class of the Fund will not incur and

pay such a Distribution (12b-1) Fee until such time as approved by the Fund’s Board of Trustees

(the “Trustees”).

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 April 1, 2026, total annual fund

operating expenses (excluding acquired fund fees and expenses, interest expense, extraordinary

expenses and proxy-related expenses, if any) paid by the Fund’s R, IS and SS classes (after the

voluntary waivers and/or reimbursements) will not exceed 1.33%, 0.60% and 0.83% (the “Fee Limit”),

respectively, up to but not including the later of (the “Termination Date”): (a) April 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 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
R	$158	$490	$845	$1,845
IS	$113	$353	$612	$1,352
SS	$116	$362	$628	$1,386

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 55% of the average value of its portfolio.

RISK/RETURN SUMMARY: INVESTMENTS, RISKS and PERFORMANCE

What are the Fund’s Main Investment Strategies?

The Fund is intended to provide returns consistent with investments in short-to-intermediate term obligations of the U.S. government and its agencies and instrumentalities. The Fund’s overall strategy is generally to invest in a portfolio consisting of U.S. Treasury securities and U.S. government agency securities such that the Fund’s average effective maturity is not less than two years and not more than five years. The Fund may also use derivative contracts and/or hybrid instruments to implement elements of its strategies, particularly to manage duration and hedge against potential losses. The Fund buys and sells portfolio securities based primarily on the market outlook and analysis of how securities may perform under different market conditions. Federated Investment Management Company, the Fund’s investment adviser (the “Adviser”), evaluates the Fund’s investment strategy by comparing the performance and

composition of the Fund’s portfolio to the performance and composition of ICE BofA 3-5 Year US Treasury Index, an index composed of U.S. Treasury notes and bonds with maturities greater than or equal to three years and less than five years. 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.

U.S. government securities also may be offered on a delayed delivery basis. The Fund will enter into delayed delivery transactions, including when-issued transactions, in order to participate in these offerings or trade these securities. The Fund may also seek to increase its income by lending its portfolio securities.

Certain of the government securities in which the Fund invests 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 (“Freddie Mac”), the Federal National Mortgage Association (“Fannie Mae”) 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 government 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 (“Ginnie Mae”). Finally, the Fund may invest in certain government securities that have no explicit financial support, but which are regarded as having implied support because the federal government sponsors their activities.

The Fund invests in overnight repurchase agreements or money market funds in order to maintain sufficient cash to pay for daily net redemptions and portfolio transactions.

The Fund may also purchase U.S. Treasury Inflation-Protected Securities. The value of inflation-protected securities is subject to the effects of changes in market interest rates caused by factors other than inflation (“real interest rates”). If interest rates rise due to reasons other than inflation, the Fund’s investment in these securities may not be protected to the extent that the increase is not reflected in the security’s inflation measure. Generally, when real interest rates rise, the value of inflation-protected securities will fall and the Fund’s value may decline as a result of this exposure to these securities. Significant risk occurs when interest rates rise and inflation declines.

The Fund may invest in government mortgage-backed securities. The government mortgage-backed securities in which the Fund may invest are government mortgage-backed securities such as those issued by Ginnie Mae, Fannie Mae and Freddie Mac.

The Fund will invest its assets so that at least 80% of its net assets (plus any borrowings for investment purposes) are invested in U.S. government 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.

■ Liquidity Risk. Trading opportunities are more limited for fixed-income securities that have not received any credit ratings, have received ratings below investment grade or are not widely held. These features may make it more difficult to sell or buy a security at a favorable price or time. Consequently, the Fund may have to accept a lower price to sell a security, sell other securities to raise cash or give up an investment opportunity, any of which could have a negative effect on the Fund’s performance. Infrequent trading of securities may also lead to an increase in their price volatility. 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 will be required to continue to hold the security or keep the position open, and the Fund could incur losses. Over-the-counter (OTC) derivative contracts generally carry greater liquidity risk than exchange-traded contracts.

■ 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, sanctions and terrorism), legislative changes, industry or economic trends and developments, 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.

■ Leverage Risk. Leverage risk is created when an investment, which includes, for example, an investment in a derivative contract, 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. Investments can have these same results if their returns are based on a multiple of a specified index, security or other benchmark.

■ 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 of Investing in Inflation-Protected Securities. The value of inflation-protected securities is subject to the effects of changes in market interest rates caused by factors other than inflation (“real interest rates”). If interest rates rise due to reasons other than inflation, the Fund’s investment in these securities may not be protected to the extent that the increase is not reflected in the security’s inflation measure. Generally, when real interest rates rise, the value of inflation-protected securities will fall and the Fund’s value may decline as a result of this exposure to these securities. The greatest risk occurs when interest rates rise and inflation declines.

■ 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 when interest rates rise.

■ 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.

■ Mortgage-Backed Securities Risk. Mortgage-backed securities (MBS) have unique risks. A rise in interest rates may cause the value of MBS held by the Fund to decline. MBS are subject to the risk that payments made on a security will not be made when due. Certain MBS issued by U.S. government-sponsored enterprises are not backed by the full faith and credit of the U.S. government.

■ 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.

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.

Within the periods shown in the bar chart, the Fund’s IS class highest quarterly return was 4.92% (quarter ended March 31, 2020). Its lowest quarterly return was (4.36)% (quarter ended March 31, 2022).

Average Annual Total Return Table

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 IS class, and after-tax returns for R and SS classes will differ from those shown for 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.
