Goldman Sachs Core Fixed Income Fund – Service Shares

Before you invest, you may want to review the Goldman Sachs Core Fixed Income Fund (the “Fund”) Prospectus, which contains more information about the Fund and its risks. You can find the Fund’s Prospectus, reports to shareholders and other information about the Fund online at dfinview.com/GoldmanSachs. You can also get this information at no cost by calling 800-621-2550 or by sending an e-mail request to gs-funds-document-requests@gs.com. The Fund’s Prospectus and Statement of Additional Information (“SAI”), both dated April 30, 2026, are incorporated by reference into this Summary Prospectus.

Investment Objective

The Goldman Sachs Core Fixed Income Fund (the “Fund”) seeks a total return consisting of capital appreciation and income.

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy, hold and sell Service Shares of the Fund. This table does not reflect the fees and expenses associated with any variable annuity contract or variable life insurance policy that uses the Fund as an investment option. Had those fees and expenses been included, overall fees and expenses would be higher.

Annual Fund Operating Expenses

(expenses that you pay each year as a percentage of the value of your investment)

Management Fees	0.40%
Distribution and Service (12b-1) Fees	0.25%
Other Expenses	0.19%
Acquired (Underlying) Fund Fees and Expenses	0.01%
Total Annual Fund Operating Expenses1	0.85%
Fee Waiver and Expense Limitation2	(0.18)%
Total Annual Fund Operating Expenses After Fee Waiver and Expense Limitation1	0.67%

The “Total Annual Fund Operating Expenses” and “Total Annual Fund Operating Expenses After Fee Waiver and Expense Limitation” do not correlate to the ratios of net and total expenses to average net assets provided in the Financial Highlights, which reflect the operating expenses of the Fund and do not include “Acquired (Underlying) Fund Fees and Expenses.”

The Investment Adviser has agreed to (i) waive a portion of its management fee in an amount equal to any management fees it earns as an investment adviser to the affiliated funds in which the Fund invests, and (ii) reduce or limit “Other Expenses” (excluding acquired fund fees and expenses, transfer agency fees and expenses, taxes, interest, brokerage fees, expenses of shareholder meetings, litigation and indemnification, and extraordinary expenses) equal on an annualized basis to 0.004% of the Fund’s average daily net assets. These arrangements will remain in effect through at least April 30, 2027, and prior to such date the Investment Adviser may not terminate the arrangement without the approval of the Board of Trustees.

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. This Example does not reflect the fees and expenses associated with any variable annuity contract or variable life insurance policy that uses the Fund as an investment option. Had those fees and expenses been included, the costs shown below would be higher. The Example assumes that you invest $10,000 in Service Shares of the Fund for the time periods indicated and then redeem all of your Service 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
Service Shares	$68	$253	$454	$1,032

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. 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 December 31, 2025 was 574% of the average value of its portfolio.

2 Summary Prospectus — Goldman Sachs Core Fixed Income Fund – Service Shares

Principal Strategy

The Fund invests, under normal circumstances, at least 80% of its net assets plus any borrowings for investment purposes (measured at the time of purchase) (“Net Assets”) in core fixed income securities. Fixed income securities include securities issued or guaranteed by the U.S. government, its agencies, instrumentalities or sponsored enterprises (“U.S. Government Securities”), including agency issued adjustable rate and fixed rate mortgage-backed securities or other mortgage-related securities (“Agency Mortgage-Backed Securities”), corporate debt securities, privately issued adjustable rate and fixed rate mortgage-backed securities or other mortgage-related securities (“Private Mortgage-Backed Securities” and, together with Agency Mortgage-Backed Securities, “Mortgage-Backed Securities”) and asset-backed securities (including collateralized loan obligations). The Fund may also invest in custodial receipts, fixed income securities issued by or on behalf of states, territories, and possessions of the United States (including the District of Columbia) (“Municipal Securities”) and convertible securities. Core fixed income securities are fixed income securities that are rated investment grade (i.e., securities rated BBB-, Baa3 or higher by a nationally recognized statistical rating organization (“NRSRO”) or, if unrated, determined by the Investment Adviser to be of comparable credit quality).

The Fund may also engage in forward foreign currency transactions for both hedging and non-hedging purposes. The Fund also intends to invest in derivatives, including (but not limited to) interest rate futures, interest rate swaps and credit default swaps, which are used primarily to hedge the Fund’s portfolio risks, manage the Fund’s duration and/or gain exposure to certain fixed income securities or indices. The Fund may gain exposure to Agency Mortgage-Backed Securities through several methods, including by utilizing to-be-announced (“TBA”) agreements in Agency Mortgage-Backed Securities or through the use of reverse repurchase agreements. TBA agreements for Agency Mortgage-Backed Securities are standardized contracts for future delivery of fixed-rate mortgage pass-through securities in which the exact mortgage pools to be delivered are not specified until shortly before settlement. A reverse repurchase agreement enables the Fund to gain exposure to specified pools of Agency Mortgage-Backed Securities by purchasing them on a forward settling basis and using the proceeds of the reverse repurchase agreement to settle the trade.

The Fund may implement short positions and may do so by using swaps, options or futures, TBA agreements in Agency Mortgage-Backed Securities, or through short sales of any instrument that the Fund may purchase for investment. For example, the Fund may enter into a futures contract pursuant to which it agrees to sell an asset (that it does not currently own) at a specified price at a specified point in the future. This gives the Fund a short position with respect to that asset. The Fund may utilize short positions to implement macro views on securities valuations, long term views on relative value or short term views on security mispricings, as well as any other views the Investment Adviser deems appropriate. For example, the Fund may enter into a TBA agreement to sell an Agency Mortgage-Backed Security that it believes will underperform. The Fund will benefit from a short position to the extent the asset decreases in value (and will be harmed to the extent the asset increases in value) between the time it enters into the futures contract and the agreed date of sale. Alternatively, the Fund may sell an instrument (e.g., a bond, or a futures contract) it does not own in anticipation of a decline in the market value of the instrument, and then borrow the instrument to make delivery to the buyer. In these transactions, the Fund is obligated to replace the instrument borrowed by purchasing it at the market price at the time of replacement.

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 investments in non-U.S. dollar denominated obligations (hedged or unhedged against currency risk) will not exceed 25% of its total assets measured at the time of purchase (“Total Assets”), and 10% of the Fund’s Total Assets may be invested in sovereign and corporate debt securities and other instruments of issuers in emerging market countries (“emerging countries debt”). Additionally, exposure to non-U.S. currencies (unhedged against currency risk) will not exceed 25% of the Fund’s Total Assets.

The Fund may invest in fixed income securities rated at least BBB– or Baa3 at the time of purchase. Securities will either be rated by an NRSRO or, if unrated, determined by the Investment Adviser to be of comparable credit quality.

The Fund’s target duration range under normal interest rate conditions is expected to approximate that of the Bloomberg U.S. Aggregate Bond Index (the “Index”) plus or minus one year, and over the last five years ended February 28, 2026, the duration of the Index has ranged between 5.79 and 6.78 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 Investment Adviser employs a fundamental investment process that may integrate environmental, social and governance (“ESG”) factors alongside traditional fundamental factors. No one factor or consideration is determinative in the fundamental investment process.

The Investment Adviser measures the Fund's performance against the Bloomberg U.S. Aggregate Bond Index.

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 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.

Collateralized Loan Obligations Risk. The Fund may invest in collateralized loan obligations (“CLOs”) and other similarly structured investments. A CLO is an asset-backed security whose underlying collateral is a pool of loans, which may include, among others, domestic and foreign floating rate and fixed rate senior secured loans, senior unsecured loans, and subordinate corporate loans, including loans that may be rated below investment grade or equivalent unrated loans. In addition to the normal risks associated with loan- and credit-related securities discussed elsewhere in the Prospectus (e.g., loan-related investments risk, interest rate risk and default risk), investments in CLOs carry additional risks including, but not limited to, the risk that: (i) distributions from the collateral may not be adequate to make interest or other payments; (ii) the quality of the collateral may decline in value or default; (iii) the Fund may invest in tranches of CLOs that are

3 Summary Prospectus — Goldman Sachs Core Fixed Income Fund – Service Shares

subordinate to other tranches; (iv) the structure and complexity of the transaction and the legal documents could lead to disputes among investors regarding the characterization of proceeds; and (v) the CLO’s manager may perform poorly.

CLOs issue classes or “tranches” that offer various maturity, risk and yield characteristics. Losses caused by defaults on underlying assets are borne first by the holders of subordinate tranches. Despite the protection from subordinate tranches, more senior tranches of CLOs can experience losses due to actual defaults, increased sensitivity to defaults due to collateral default and disappearance of more subordinate tranches, market anticipation of defaults, as well as aversion to CLO securities as a class. The Fund’s investments in CLOs primarily consist of investment grade tranches.

Credit/Default Risk. An issuer or guarantor of fixed income securities or instruments held by the Fund may default on its obligation to pay interest and repay principal or default on any other obligation. Additionally, the credit quality of securities 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.

Derivatives Risk. The Fund's use of options, forwards, interest rate futures, interest rate swaps, credit default swaps 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 and Emerging Countries 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 exchange 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. These risks are more pronounced in connection with the Fund’s investments in securities of issuers located in, or otherwise economically tied to, emerging countries.

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 yield and 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. 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 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.

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,

4 Summary Prospectus — Goldman Sachs Core Fixed Income Fund – Service Shares

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.

Mortgage-Backed and Other Asset-Backed Securities Risk. Mortgage-related and other asset-backed securities are subject to credit/default, interest rate and certain additional risks, including “extension risk” (i.e., in periods of rising interest rates, issuers may pay principal later than expected) and “prepayment risk” (i.e., in periods of declining interest rates, issuers may pay principal more quickly than expected, causing the Fund to reinvest proceeds at lower prevailing interest rates). Due to these risks, asset-backed securities may become more volatile in certain interest rate environments. Mortgage-backed securities offered by non-governmental issuers are subject to other risks as well, including failures of private insurers to meet their obligations and unexpectedly high rates of default on the mortgages backing the securities, particularly during periods of rising interest rates. Other asset-backed securities are subject to risks similar to those associated with mortgage-backed securities, as well as risks associated with the nature and servicing of the assets backing the securities. Asset-backed securities may not have the benefit of a security interest in collateral comparable to that of mortgage assets, resulting in additional credit risk.

The Fund may gain exposure to Agency Mortgage-Backed Securities by utilizing TBA agreements. TBA agreements involve the risk that the other party to the transaction will not meet its obligation. If this occurs, the Fund could lose the opportunity to obtain a price or yield that it considers advantageous. In such circumstances, the Fund may not be able to secure an alternative investment with comparable terms. TBA agreements may give rise to a form of leverage. The Fund’s use of TBA agreements may also result in a higher portfolio turnover rate and/or increased capital gains for the Fund.

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.

Portfolio Turnover Rate Risk. A high rate of portfolio turnover may involve correspondingly greater expenses which must be borne by the Fund and its shareholders.

Reverse Repurchase Agreements Risk. Reverse repurchase agreements are a form of secured borrowing and subject the Fund to the risks associated with leverage, including exposure to potential gains and losses in excess of the amount invested. Reverse repurchase agreements involve the risk that the investment return earned by the Fund (from the investment of the proceeds) will be less than the interest expense of the transaction, that the market value of the securities sold by the Fund will decline below the price the Fund is obligated to pay to repurchase the securities, and that the other party may fail to return the securities in a timely manner or at all.

Short Position Risk. The Fund may enter into a short position through a futures contract, an option or swap agreement or through short sales of any instrument that the Fund may purchase for investment. Taking short positions involves leverage of the Fund’s assets and presents various risks. If the value of the underlying instrument or market in which the Fund has taken a short position increases, then the Fund will incur a loss equal to the increase in value from the time that the short position was entered into plus any related interest payments or other fees. Taking short positions involves the risk that losses may be disproportionate,

may exceed the amount invested and may be unlimited. To the extent that the Fund uses the proceeds it receives from a short position to take additional long positions, the risks associated with the short position, including leverage risks, may be heightened, because doing so increases the exposure of the Fund to the markets and therefore could magnify changes to the Fund’s NAV.

Tax Diversification Risk. The Fund intends to meet the diversification requirements that are applicable to insurance company separate accounts under Subchapter L of the Internal Revenue Code of 1986, as amended (the “Code”) (the “Diversification Requirements”). In order for the Fund to qualify for “look through” treatment under the Diversification Requirements, Fund shares must be sold only to persons permitted to hold shares, directly or indirectly (each, a “Permitted Investor”), under Section 817 of the Code and Treasury Regulation 1.817-5(f), as supplemented by published rulings and procedures issued thereunder by the Internal Revenue Service (“IRS”). To the extent an investor in Fund shares no longer qualifies as a Permitted Investor, and such investor fails to restore its status as a Permitted Investor or obtain a waiver or closing agreement with respect to such failure from the IRS, the Fund may no longer qualify for “look through” treatment. Therefore, in testing compliance with the Diversification Requirements, an investor in the Fund, such as, for example, an insurance company separate account, no longer would be able to look through the Fund to its underlying investments. Instead, the Fund would be considered a single investment for purposes of the Diversification Requirements.

A failure to satisfy the Diversification Requirements (whether resulting from investors in Fund shares or otherwise) could have significant adverse tax consequences for variable contract owners whose contract values are determined by investment in the Fund. See “Taxation” in the Statement of Additional Information (the “SAI”) for more information.

U.S. Government Securities Risk. The U.S. government may not provide financial support to U.S. government agencies, instrumentalities or sponsored enterprises if it is not obligated to do so by law. U.S. Government Securities issued by the Federal National Mortgage Association (“Fannie Mae”), Federal Home Loan Mortgage Corporation (“Freddie Mac”) and the Federal Home Loan Banks, are neither issued nor guaranteed by the U.S. Treasury and, therefore, are not backed by the full faith and credit of the United States. The maximum potential liability of the issuers of some U.S. Government Securities held by the Fund may greatly exceed their current resources, including any legal right to support from the U.S. Treasury. It is possible that issuers of U.S. Government Securities will not have the funds to meet their payment obligations in the future.

Buying and Selling Fund Shares

Fund shares are not sold directly to the public. Fund shares may be purchased and redeemed by separate accounts that fund variable annuity and variable life insurance contracts issued by participating insurance companies and other qualified purchasers. Orders received from separate accounts and other qualified purchasers to purchase or redeem Fund shares are effected on business days. Individual investors may purchase or redeem Fund shares indirectly through variable annuity contracts and variable life insurance policies offered through the separate accounts.

Tax Information

Provided that the Fund and separate accounts investing in the Fund satisfy applicable tax requirements, the Fund will not be subject to federal tax. Special tax rules apply to life insurance companies, variable annuity contracts and variable life insurance contracts. For information on federal income taxation of owners of variable annuity or variable life insurance contracts, see the prospectus for the applicable contract.

Payments to Broker-Dealers and

Other Financial Intermediaries

The Fund and/or its related companies may pay participating insurance companies and securities dealers for the sale of Fund shares and related services. These payments may create a conflict of interest by influencing the insurance company and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your insurance company’s website for more information.
