2 Summary Prospectus — Goldman Sachs High Yield Floating Rate Fund

Expense 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 in Class A, Class C, Institutional, Investor, Class R and/or Class R6 Shares of the Fund for the time periods indicated and then redeem all of your Class A, Class C, Institutional, Investor, Class R and/or Class R6 Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same (except that the Example incorporates any applicable fee waiver and/or expense limitation arrangements for only the first year). Although your actual costs may be higher or lower, based on these assumptions your costs would be:

	1 Year	3 Years	5 Years	10 Years
Class A Shares	$327	$553	$797	$1,497
Class C Shares	$280	$568	$981	$2,133
Institutional Shares	$76	$237	$411	$918
Investor Shares	$79	$257	$450	$1,009
Class R Shares	$129	$413	$719	$1,586
Class R6 Shares	$75	$233	$406	$906

Portfolio Turnover

The Fund pays transaction costs when it buys and sells securities or instruments (i.e., “turns over” its portfolio). A high rate of portfolio turnover may result in increased transaction costs, which must be borne by the Fund and its shareholders, and is also likely to result in higher short-term capital gains for taxable shareholders. These costs are not reflected in the annual fund operating expenses or in the expense example above, but are reflected in the Fund’s performance. The Fund’s portfolio turnover rate for the fiscal year ended March 31, 2026 was 53% of the average value of its portfolio.

Principal Strategy

The Fund invests, under normal circumstances, at least 80% of its net assets plus any borrowings for investment purposes (“Net Assets”) in domestic or foreign floating rate loans and other floating or variable rate obligations rated below investment grade. Non-investment grade obligations are those rated BB+, Ba1 or below by a nationally recognized statistical rating organization (“NRSRO”), or, if unrated, determined by the Investment Adviser to be of comparable credit quality, and are commonly referred to as “junk bonds.”

The Fund’s investments in floating and variable rate obligations may include, without limitation, senior secured loans (including assignments and participations), second lien loans, senior unsecured and subordinated loans, senior and subordinated corporate debt obligations (such as bonds, debentures, notes and commercial paper), debt issued by governments, their agencies and instrumentalities, and debt issued by central banks. The Fund may invest indirectly in loans by purchasing participations or sub-participations from financial institutions. Participations and sub-participations represent the right to receive a portion of the principal of, and all of the interest relating to such portion of, the applicable loan. The Fund expects to invest principally in the U.S. loan market and, to a lesser extent, in the European loan market. The Fund may also invest in other loan markets, although it does not currently intend to do so.

Under normal conditions, the Fund may invest up to 20% of its Net Assets in fixed income instruments, of any credit rating, including fixed rate corporate bonds, government bonds, convertible debt obligations, and mezzanine fixed income instruments. The Fund may also invest in floating or variable rate instruments that are rated investment grade and in preferred stock, repurchase agreements and cash securities.

The Fund may also invest in derivative instruments. Derivatives are instruments that have a value based on another instrument, exchange rate or index. The Fund’s investments in derivatives may include credit default swaps on credit and loan indices, forward contracts and total return swaps, among others. The Fund may use currency management techniques, such as forward foreign currency contracts, for hedging or non-hedging purposes. The Fund may invest in interest rate futures and swaps to manage the portfolio’s duration. Derivatives that provide exposure to floating or variable rate loans or obligations rated below investment grade are counted towards the Fund’s 80% policy.

The Fund may also seek to obtain exposure to fixed income investments through investments in affiliated or unaffiliated investment companies, including exchange-traded funds (“ETFs”).

The Fund’s target duration range under normal interest rate conditions is expected to approximate that of the S&P UBS Leveraged Loan Index (Total Return, USD, Unhedged), plus or minus one year, and over the last five years ended June 30, 2026, the duration of this index has ranged between 0.01 and 0.19 years. The Fund’s investments in floating rate obligations will generally have short to intermediate maturities (approximately 4-7 years). “Duration” is a measure of a debt security’s price sensitivity to changes in interest rates. The longer the duration of the Fund (or an individual debt security), the more sensitive its market price to changes in interest rates. For example, if market interest rates increase by 1%, the market price of a debt security with a positive duration of 3 years will generally decrease by approximately 3%. Conversely, a 1% decline in market interest rates will generally result in an increase of approximately 3% of that security’s market price.

The Fund’s investments are selected using a bottom-up analysis that incorporates fundamental research, a focus on market conditions and pricing trends, quantitative research, and news or market events. As part of the Investment Adviser’s fundamental investment process, the Investment Adviser may integrate environmental, social and governance (“ESG”) factors alongside traditional fundamental factors. The selection of individual investments is based on the overall risk and return profile of the investment taking into account liquidity, structural complexity, cash flow uncertainty and downside potential. Research analysts and portfolio managers systematically assess portfolio positions, taking into consideration, among other factors, broader macroeconomic conditions and industry and company-specific financial performance and outlook. Based upon this analysis, the Investment Adviser will sell positions determined to be overvalued and reposition the portfolio in more attractive investment opportunities on a relative basis given the current climate. No one factor or consideration is determinative in the fundamental investment process.

The Investment Adviser measures the Fund’s performance against the S&P UBS Leveraged Loan Index (Total Return, USD, Unhedged).

Principal Risks of the Fund

Loss of money is a risk of investing in the Fund. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (“FDIC”) or any government agency. The Fund should not be relied upon as a complete investment program. There can be no assurance that the Fund will achieve its investment objective. Investments in the Fund

3 Summary Prospectus — Goldman Sachs High Yield Floating Rate Fund

involve substantial risks which prospective investors should consider carefully before investing. The Fund's principal risks are presented below in alphabetical order, and not in the order of importance or potential exposure.

Conflict of Interest Risk. Affiliates of the Investment Adviser may participate in the primary and secondary market for loan obligations. Because of limitations imposed by applicable law, the presence of the Investment Adviser’s affiliates in the loan obligations market may restrict the Fund’s ability to acquire some loan obligations or affect the timing or price of such acquisitions. Also, because the Investment Adviser may wish to invest in the publicly traded securities of a borrower, it may not have access to material non-public information regarding the borrower to which other lenders have access.

Credit/Default Risk. An issuer or guarantor of fixed income securities or instruments held by the Fund (which may have low credit ratings) may default on its obligation to pay interest and repay principal or default on any other obligation. Additionally, the credit quality of securities or instruments may deteriorate rapidly, which may impair the Fund’s liquidity and cause significant deterioration in net asset value (“NAV”). These risks are heightened in market environments where interest rates are rising as well as in connection with the Fund’s investments in non-investment grade fixed income securities.

Currency Risk. Indirect and direct exposure to foreign currencies subjects the Fund to the risk that those currencies will decline in value relative to the U.S. dollar, which would cause a decline in the U.S. value of the holdings of the Fund. Currency rates in foreign countries may fluctuate significantly over short periods of time for a number of reasons, including changes in interest rates and the imposition of currency controls or other political, economic and tax developments in the U.S. or abroad. To the extent the Fund seeks exposure to foreign currencies through foreign currency contracts and related transactions, the Fund becomes particularly susceptible to foreign currency value fluctuations, which may be sudden and significant, and investment decisions tied to currency markets. In addition, these investments are subject to the risks associated with derivatives and hedging and the impact on the Fund of fluctuations in the value of currencies may be magnified.

Derivatives Risk. The Fund's use of credit default swaps, total return swaps, futures, forwards and other derivative instruments may result in losses, including due to adverse market movements. These instruments, which may pose risks in addition to and greater than those associated with investing directly in securities, currencies or other assets and instruments, may increase market exposure and be illiquid or less liquid, volatile, difficult to price and leveraged so that small changes in the value of the underlying assets or instruments may produce disproportionate losses to the Fund. Certain derivatives are also subject to counterparty risk, which is the risk that the other party in the transaction will not fulfill its contractual obligations. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with investments in more traditional securities and instruments.

Floating and Variable Rate Obligations Risk. For floating and variable rate obligations, there may be a lag between an actual change in the underlying interest rate benchmark and the reset time for an interest payment of such an obligation, which could harm or benefit the Fund, depending on the interest rate environment or other circumstances. In a rising interest rate environment, for example, a floating or variable rate obligation that does not reset immediately would prevent the Fund from taking full advantage of rising interest rates in a timely manner.

However, in a declining interest rate environment, the Fund may benefit from a lag due to an obligation’s interest rate payment not being immediately impacted by a decline in interest rates.

Certain floating and variable rate obligations have an interest rate floor feature, which prevents the interest rate payable by the security from dropping below a specified level as compared to a reference interest rate (the “reference rate”), such as the Secured Overnight Financing Rate (“SOFR”), a term SOFR rate published by CME Group Benchmark Administration Limited (CBA) calculated using certain derivatives markets (“Term SOFR”) or another rate determined using SOFR values. Such a floor protects the Fund from losses resulting from a decrease in the reference rate below the specified level. However, if the reference rate is below the floor, there will be a lag between a rise in the reference rate and a rise in the interest rate payable by the obligation, and the Fund may not benefit from increasing interest rates for a significant amount of time.

Foreign Risk. Foreign securities may be subject to risk of loss because of more or less foreign government regulation; less public information; less stringent investor protections; less stringent accounting, corporate governance, financial reporting and disclosure standards; and less economic, political and social stability in the countries in which the Fund invests. The imposition of sanctions, exchange controls (including repatriation restrictions), confiscations, trade restrictions (including tariffs) and other government restrictions by the United States and other governments, or from problems in share registration, settlement or custody, may also result in losses. The type and severity of sanctions and other similar measures, including counter sanctions and other retaliatory actions, that may be imposed could vary broadly in scope, and their impact is impossible to predict. For example, the imposition of sanctions and other similar measures could, among other things, cause a decline in the value and/or liquidity of securities issued by the sanctioned country or companies located in or economically tied to the sanctioned country and increase market volatility and disruption in the sanctioned country and throughout the world. Sanctions and other similar measures could limit or prevent the Fund from buying and selling securities (in the sanctioned country and other markets), significantly delay or prevent the settlement of securities transactions, and significantly impact the Fund’s liquidity and performance. Foreign risk also involves the risk of negative foreign currency rate fluctuations, which may cause the value of securities denominated in such foreign currency (or other instruments through which the Fund has exposure to foreign currencies) to decline in value. Currency exchange rates may fluctuate significantly over short periods of time.

Interest Rate Risk. When interest rates increase, fixed income securities or instruments held by the Fund will generally decline in value. Long-term fixed income securities or instruments will normally have more price volatility because of this risk than short-term fixed income securities or instruments. Changing interest rates may have unpredictable effects on the markets, may result in heightened market volatility and may detract from Fund performance. In addition, changes in monetary policy may exacerbate the risks associated with changing interest rates. Funds with longer average portfolio durations will generally be more sensitive to changes in interest rates than funds with a shorter average portfolio duration. Fluctuations in interest rates may also affect the liquidity of fixed income securities and instruments held by the Fund.

Large Shareholder Transactions Risk. The Fund may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Fund. Such large shareholder redemptions, which may occur rapidly or unexpectedly, may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund's NAV and liquidity.

4 Summary Prospectus — Goldman Sachs High Yield Floating Rate Fund

Similarly, large Fund share purchases may adversely affect the Fund's performance to the extent that the Fund is delayed in investing new cash or otherwise maintains a larger cash position than it ordinarily would. These transactions may also accelerate the realization of taxable income to shareholders if such sales of investments resulted in gains, and may also increase transaction costs. In addition, a large redemption could result in the Fund's current expenses being allocated over a smaller asset base, leading to an increase in the Fund's expense ratio.

Liquidity Risk. The Fund may make investments that are illiquid or that may become less liquid in response to market developments or adverse investor perceptions. Illiquid investments may be more difficult to value. Liquidity risk may also refer to the risk that the Fund will not be able to pay redemption proceeds within the allowable time period because of unusual market conditions, declining prices of the securities sold, an unusually high volume of redemption requests or other reasons. To meet redemption requests, the Fund may be forced to sell investments, at an unfavorable time and/or under unfavorable conditions. Liquidity risk may be the result of, among other things, the reduced number and capacity of traditional market participants to make a market in fixed income securities or the lack of an active market. The potential for liquidity risk may be magnified by a rising interest rate environment or other circumstances where investor redemptions from fixed income funds may be higher than normal, potentially causing increased supply in the market due to selling activity. Redemptions by large shareholders may have a negative impact on the Fund’s liquidity.

Loan-Related Investments Risk. In addition to risks generally associated with debt investments (e.g., interest rate risk and default risk), loan-related investments such as loan participations and assignments are subject to other risks. Although a loan obligation may be fully collateralized at the time of acquisition, the collateral may decline in value, be or become illiquid or less liquid, or lose all or substantially all of its value subsequent to investment. Many loan investments are subject to legal or contractual restrictions on resale and certain loan investments may be or become illiquid or less liquid and more difficult to value, particularly in the event of a downgrade of the loan or the borrower. There is less readily available, reliable information about most loan investments than is the case for many other types of securities. Substantial increases in interest rates may cause an increase in loan obligation defaults. With respect to loan participations, the Fund may not always have direct recourse against a borrower if the borrower fails to pay scheduled principal and/or interest; may be subject to greater delays, expenses and risks than if the Fund had purchased a direct obligation of the borrower; and may be regarded as the creditor of the agent lender or counterparty (rather than the borrower), subjecting the Fund to the creditworthiness of that lender as well. Investors in loans, such as the Fund, may not be entitled to rely on the anti-fraud protections of the federal securities laws, although they may be entitled to certain contractual remedies.

The market for loan obligations may be subject to irregular trading activity, wide bid/ask spreads and extended trade settlement periods. Because transactions in many loans are subject to extended trade settlement periods, the Fund may not receive the proceeds from the sale of a loan for a period after the sale. As a result, sale proceeds related to the sale of loans may not be available to make additional investments or to meet the Fund's redemption obligations for a period after the sale of the loans, and, as a result, the Fund may have to sell other investments or engage in borrowing transactions, such as borrowing from its credit facility, if necessary to raise cash to meet its obligations. During periods of heightened redemption activity or distressed market conditions, the Fund may seek to obtain expedited trade settlement, which will generally incur additional costs (although expedited trade settlement will not always be available).

Senior loans hold the most senior position in the capital structure of a business entity, and are typically secured with specific collateral, but are nevertheless usually rated below investment grade. Because second lien loans are subordinated or unsecured and thus lower in priority of payment to senior loans, they are subject to the additional risk that the cash flow of the borrower and property securing the loan or debt, if any, may be insufficient to meet scheduled payments after giving effect to the senior secured obligations of the borrower. Second lien loans generally have greater price volatility than senior loans and may be less liquid. Generally, loans have the benefit of restrictive covenants that limit the ability of the borrower to further encumber its assets or impose other obligations. To the extent a loan does not have certain covenants (or has less restrictive covenants), an investment in the loan will be particularly sensitive to the risks associated with loan investments.

Market Risk. The value of the securities in which the Fund invests may go up or down in response to the prospects of individual companies, particular sectors, governments or countries and/or general economic conditions throughout the world due to increasingly interconnected global economies and financial markets. Events such as war, military conflict, geopolitical disputes, acts of terrorism, social or political unrest, natural disasters, recessions, inflation, rapid interest rate changes, supply chain disruptions, tariffs and other restrictions on trade, sanctions or the spread of infectious illness or other public health threats, or the threat or potential of one or more such events and developments, could also significantly impact the Fund and its investments.

Non-Investment Grade Fixed Income Securities Risk. Non-investment grade fixed income securities and unrated securities of comparable credit quality (commonly known as “junk bonds”) are considered speculative and are subject to the increased risk of an issuer’s inability to meet principal and interest payment obligations. These securities may be subject to greater price volatility due to such factors as specific issuer developments, interest rate sensitivity, negative perceptions of the junk bond markets generally and less liquidity.

Other Investment Companies Risk. By investing in other investment companies (including ETFs) indirectly through the Fund, investors will incur a proportionate share of the expenses of the other investment companies held by the Fund (including operating costs and investment management fees) in addition to the fees regularly borne by the Fund. In addition, the Fund will be affected by the investment policies, practices and performance of such investment companies in direct proportion to the amount of assets the Fund invests therein. To the extent the Fund invests in ETFs, the Fund will invest only in ETFs sponsored by GSAM or its affiliates, unless GSAM determines, in its sole discretion, that no affiliated ETF is available to provide the desired exposure (for example, by sector, industry, credit quality, or duration). GSAM will consider investing in an unaffiliated ETF on behalf of the Fund only where no affiliated ETF is available to provide the desired exposure. For investments in affiliated ETFs, GSAM has agreed to waive a portion of its management fees in an amount equal to any management fees it earns as the investment adviser to the affiliated ETFs.

Performance

The bar chart and table below provide an indication of the risks of investing in the Fund by showing: (a) changes in the performance of the Fund’s Class A Shares from year to year; and (b) how the average annual total returns of the Fund’s Class A, Class C, Institutional, Investor, Class R and Class R6 Shares compare to those of a regulatorily required broad-based securities market index (Bloomberg U.S. Aggregate Bond Index) (the “Regulatory Benchmark”) and the S&P UBS Leveraged Loan Index (Total Return, USD, Unhedged) (the

5 Summary Prospectus — Goldman Sachs High Yield Floating Rate Fund

“Performance Benchmark”). The Performance Benchmark is generally more representative of the market sectors and/or types of investments in which the Fund invests or to which the Fund has exposure and which the Investment Adviser uses to measure the Fund’s performance. The Fund has included in the table below the performance of the Regulatory Benchmark, which represents a broader measure of market performance, to comply with regulatory requirements. For additional information about these benchmark indices, please see “Additional Performance and Benchmark Information” on page 49 of the Prospectus. The Fund’s past performance, before and after taxes, is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available at no additional cost at am.gs.com or by calling the appropriate phone number on the back cover of the Prospectus.

The bar chart (including “Best Quarter” and “Worst Quarter” information) does not reflect the sales loads applicable to Class A Shares. If the sales loads were reflected, returns would be less. Performance reflects applicable fee waivers and/or expense limitations in effect during the periods shown.

Benchmark returns do not reflect any deductions for fees or expenses.

Class C Shares automatically convert into Class A Shares eight years after the purchase date. The since inception performance for Class C Shares does not reflect the conversion to Class A Shares after the first eight years of performance.

Class R6 Shares commenced operations on November 30, 2017. Prior to that date, the performance of Class R6 Shares shown in the table above is that of Institutional Shares. Performance has not been adjusted to reflect the lower expenses of Class R6 Shares. Class R6 Shares would have had higher returns because: (i) Institutional Shares and Class R6 Shares represent interests in the same portfolio of securities; and (ii) Class R6 Shares have lower expenses.

The after-tax returns are for Class A Shares only. The after-tax returns for Class C, Institutional, Investor and Class R6 Shares, and returns for Class R Shares (which are offered exclusively to employee benefit plans), will vary. After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. In addition, the after-tax returns shown are not relevant to investors who hold Fund shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts.

CFA, Managing Director, Co-Head of Leveraged Credit, has managed the Fund since 2026; and Alex Karam, Managing Director, Head of Bank Loans, has managed the Fund since 2026.

Buying and Selling Fund Shares

The minimum initial investment for Class A and Class C Shares is, generally, $1,000. The minimum initial investment for Institutional Shares is, generally, $1,000,000 for individual or certain institutional investors alone or in combination with other assets under the management of the Investment Adviser and its affiliates. There is no minimum for initial purchases of Investor, Class R and Class R6 Shares, except for certain institutional investors who purchase Class R6 Shares directly with the Fund’s transfer agent for which the minimum initial investment is $5,000,000. Those share classes with a minimum initial investment requirement do not impose it on certain employee benefit plans, and Institutional Shares do not impose it on certain investment advisers investing on behalf of other accounts.

The minimum subsequent investment for Class A and Class C shareholders is $50, except for certain employee benefit plans, for which there is no minimum. There is no minimum subsequent investment for Institutional, Investor, Class R or Class R6 shareholders.

You may purchase and redeem (sell) shares of the Fund on any business day through certain intermediaries that have a relationship with Goldman Sachs & Co. LLC (“Goldman Sachs”), including banks, trust companies, brokers, registered investment advisers and other financial institutions (“Intermediaries”).

Tax Information

The Fund’s distributions are taxable, and will be taxed as ordinary income or capital gains, unless you are investing through a tax-deferred arrangement, such as a 401(k) plan or an individual retirement account. Investments made through tax-deferred arrangements may become taxable upon withdrawal from such arrangements.

Payments to Broker-Dealers and

Other Financial Intermediaries

If you purchase shares of the Fund through an intermediary, the Fund and/or 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 intermediary and your salesperson to recommend the Fund over another investment.
