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 December 29, 2020, are incorporated by reference into this Summary Prospectus.

It is our intention that beginning on January 1, 2021, paper copies of the Fund’s annual and semi-annual shareholder reports will not be sent by mail, unless you specifically request paper copies of the reports from the Fund or from your financial intermediary. Instead, the reports will be made available on a website, and you will be notified by mail each time a report is posted and provided with a website link to access the report.

If you already elected to receive shareholder reports electronically, you will not be affected by this change and you need not take any action. At any time, you may elect to receive reports and certain communications from the Fund electronically by calling the toll-free number below or by contacting your financial intermediary.

You may elect to receive all future shareholder reports in paper free of charge. If you hold shares of the Fund directly with the Fund’s transfer agent, you can inform the transfer agent that you wish to receive paper copies of reports by calling toll-free 800-621-2550. If you hold shares of the Fund through a financial intermediary, please contact your financial intermediary to make this election. Your election to receive reports in paper will apply to all Goldman Sachs Funds held in your account if you invest through your financial intermediary or all Goldman Sachs Funds held with the Fund’s transfer agent if you invest directly with the transfer agent.

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 Select Shares of the Fund for the time periods indicated and then redeem all of your Select 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. 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
Select Shares	$22	$68	$118	$268

Principal Strategy

The Fund pursues its investment objective by investing only in “government securities,” as such term is defined in or interpreted under the Investment Company Act of 1940, as amended (“Investment Company Act”), and repurchase agreements collateralized by such securities. “Government securities” generally are securities issued or guaranteed by the United States or certain U.S. government agencies or instrumentalities (“U.S. Government Securities”).

The Fund intends to be a “government money market fund,” as such term is defined in or interpreted under Rule 2a-7 under the Investment Company Act. “Government money market funds” are money market funds that invest at least 99.5% of their total assets in cash, U.S. Government Securities, and/or repurchase agreements that are collateralized fully by cash or U.S. Government Securities. “Government money market funds” are exempt from requirements that permit money market funds to impose a “liquidity fee” and/or “redemption gate” that temporarily restricts redemptions. As a “government money market fund,” the Fund values its securities using the amortized cost method. The Fund seeks to maintain a stable net asset value (“NAV”) of $1.00 per share.

Under Rule 2a-7, the Fund may invest only in U.S. dollar-denominated securities that meet certain risk-limiting conditions relating to portfolio quality, maturity and liquidity.

Principal Risks of the Fund

You could lose money by investing in the Fund. Although the Fund seeks to preserve the value of your investment at $1.00 per share, it cannot guarantee it will do so. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not expect that the sponsor will provide financial support to the Fund at any time. 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. The Fund's principal risks are presented below in alphabetical order, and not in the order of importance or potential exposure.

Credit/Default Risk.  An issuer or guarantor of a security held by the Fund, or a bank or other financial institution that has entered into a repurchase agreement with 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 NAV.

Interest Rate Risk.  When interest rates increase, the Fund’s yield will tend to be lower than prevailing market rates, and the market value of its investments will generally decline. The risks associated with changing interest rates may have unpredictable effects on the markets and the Fund’s investments. A low or negative interest rate environment poses additional risks to the Fund, because low or negative yields on the Fund’s portfolio holdings may have an adverse impact on the Fund’s ability to provide a positive yield to its shareholders, pay expenses out of current income, or, at times, maintain a stable $1.00 share price and/or achieve its investment objective. Fluctuations in interest rates may also affect the liquidity of the Fund’s investments.

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 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. The liquidity of portfolio securities can deteriorate rapidly due to credit events affecting issuers or guarantors, such as a credit rating downgrade, or due to general market conditions or a lack of willing buyers. An inability to sell one or more portfolio positions, or selling such positions at an unfavorable time and/or under unfavorable conditions, can adversely affect the Fund’s ability to maintain a stable $1.00 share price. 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, an unusually high volume of redemption requests, or other reasons. 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 money market and other fixed income mutual funds may be higher than normal, potentially causing increased supply in the market due to selling activity.

Market Risk. The market value of the securities in which the Fund invests may go up or down in response to the prospects of individual companies, particular sectors or governments and/or general economic conditions throughout the world due to increasingly interconnected global economies and financial markets. Events such as war, acts of terrorism, social unrest, natural disasters, the spread of infectious illness or other public health threats could also significantly impact the Fund and its investments.

Stable NAV Risk.  The Fund may not be able to maintain a stable $1.00 share price at all times. If any money market fund that intends to maintain a stable NAV fails to do so (or if there is a perceived threat of such a failure), other such money market funds, including the Fund, could be subject to increased redemption activity, which could adversely affect the Fund’s NAV. Shareholders of the Fund should not rely on or expect the Investment Adviser or an affiliate to purchase distressed

assets from the Fund, make capital infusions into the Fund, enter into capital support agreements with the Fund or take other actions to help the Fund maintain a stable $1.00 share price.

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. Certain U.S. Government Securities, including securities issued by the Federal National Mortgage Association (“Fannie Mae”), Federal Home Loan Mortgage Corporation (“Freddie Mac”) and 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

Generally, Select Shares may be purchased only 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”) that have agreed to provide certain administration services to their customers who are the beneficial owners of Select Shares. The minimum initial investment requirement imposed upon Intermediaries for the purchase of Select Shares is generally $10 million, and there is no minimum imposed upon additional investments. Intermediaries may, however, impose a minimum amount for initial and additional investments in Select Shares, and may establish other requirements such as a minimum account balance.

Investments in the Investor Funds^SM are limited to accounts beneficially owned by natural persons.

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 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. Ask your salesperson or visit your Intermediary’s website for more information.
