     Goldman Sachs Momentum Builder® Focus ER Index

    

The Goldman Sachs Momentum Builder® Focus ER Index (the index) measures the performance of a “base index” and non-interest bearing cash positions subject to certain deductions, as described in further detail below. On each index business day, exposure to the base index will be reduced and exposure to the non-interest bearing cash positions increased if (i) the realized volatility of the base index exceeds a volatility control limit of 5% (we refer to the base index, after applying this volatility control limit, as the “volatility controlled index”) or (ii) the volatility controlled index has exhibited negative price momentum.

The base index is composed of underlying assets, which consist of (i) nine underlying indices, potentially providing exposure to the following asset classes: focused U.S. equities; other developed market equities; developed market fixed income; emerging market equities; and commodities; and (ii) a money market position that accrues interest at a rate equal to the federal funds rate (the “return-based money market position”). The base index rebalances on each index business day based on historical returns of the underlying assets, subject to a limitation on realized volatility (which is separate from the volatility control mechanism described in the paragraph above) and minimum and maximum weights for the underlying assets and asset classes. As a result of the rebalancing, the base index may include as few as 2 underlying assets (including the return-based money market position) and may never include some of the underlying indices or asset classes.

The daily base index return is subject to a deduction equal to the return on the federal funds rate and, in addition, the entire index is subject to a deduction of 0.65% per annum (accruing daily).

The net effect of the deduction for the federal funds rate on the base index and the 0.65% deduction on the full index means that any aggregate exposure to the return-based money market position or the non-interest bearing cash positions will reduce the index performance on a pro rata basis by 0.65%. A very significant portion of the index has been, and may be in the future, allocated to the return-based money market position and the non-interest bearing cash positions.

     Historical Information and Hypothetical Data

    

     The following chart and table provide a comparison between the index (using historical information and hypothetical data, as explained below) and certain asset classes (in each case, represented by a benchmark ETF or a benchmark index, which are distinct from the asset classes in which the 10 underlying assets have been categorized for purposes of this index) from January 1, 2021 to July 1, 2026.

Your investment in securities linked to the index involves certain risks. See “Selected Risk Factors” on page S-4 to read about investment risks relating to such securities.

Neither the Securities and Exchange Commission nor any other regulatory body has approved or disapproved of these securities or passed upon the accuracy or adequacy of this index supplement addendum, the applicable pricing supplement, the applicable product supplement, if any, the accompanying MOBU Focus ER index supplement, the accompanying prospectus supplement or the accompanying prospectus. Any representation to the contrary is a criminal offense.

The securities are not bank deposits and are not insured by the Federal Deposit Insurance Corporation or any other governmental agency, nor are they obligations of, or guaranteed by, a bank.

Benchmark ETF data and benchmark index data is based on the historical levels of the benchmark ETFs and benchmark indices, respectively. The historical index information from January 12, 2021 (the index launch date) to July 1, 2026 reflects the actual performance of the index. (In the chart, this historical index information can be found to the right of the vertical solid line marker.) The hypothetical index data from January 1, 2021 to January 11, 2021 is based on the historical levels of the eligible underlying assets, using the same methodology that is used to calculate the index. As a result, the above chart and table do not reflect the global financial crisis which began in 2008, which had a materially negative impact on certain of the benchmark ETFs, benchmark indices and eligible underlying assets and would have had a materially negative impact on the index. Please also note that the benchmark ETFs and benchmark indices that are used to represent asset classes for purposes of the above table and chart may not be eligible underlying assets for purposes of the index and in some cases differ from the eligible underlying assets that are used to represent asset classes with the same or similar titles for purposes of the index. You should not take the historical index information, hypothetical index data or historical benchmark ETF and benchmark index data as an indication of the future performance of the index.

     Monthly Performance Since January 2021

    

The following chart sets forth hypothetical and historical monthly index performance data during the period from January 1, 2021 to June 30, 2026 based on the historical index information and hypothetical index data previously supplied above. You should not take the historical index information or hypothetical index data as an indication of the future performance of the index.

     Composition Weightings

    

As of July 1, 2026, the following chart sets forth the weighting of each eligible base index underlying asset in the base index as of July 1, 2026 and the hypothetical and historical average percentage weightings of the eligible base index underlying assets, the highest percentage weightings of the eligible base index underlying assets and the percentage of index business days with positive weightings for the eligible base index underlying assets in the base index from January 1, 2021 to July 1, 2026 (the period for which eligible base index underlying assets is available). This data reflects the same historical information and hypothetical data as in the previous tables. You should not take the historical information or hypothetical data as an indication of the future performance of the index.


Eligible Base Index Underlying Asset	Weighting (as of July 1, 2026)	Average Weighting	Highest Weighting	Percentage of Index Business Days When Eligible Base Index Underlying Asset is Included as a Base Index Underlying Asset
US Equity Futures Rolling Strategy Index	12.99%	17.11%	30.00%	99.45%
US Technology Equity Futures Rolling Strategy Series Q Total Return Index	7.03%	4.35%	20.00%	64.97%

     Eligible Base Index Underlying Assets 

    

The following is a list of the eligible base index underlying assets for the index, including the related base index asset classes, base index asset class minimum and maximum weights and base index underlying asset minimum and maximum weights.


Base Index Asset Class	Base Index Asset Class Minimum Weight	Base Index Asset Class Maximum Weight	Eligible Base Index Underlying Asset	Ticker	Base Index Underlying Asset Minimum Weight	Base Index Underlying Asset Maximum Weight
Focused US Equities	20%	50%	US Equity Futures Rolling Strategy Index	FRSIUSE	0%**	30%
Focused US Equities	20%	50%	US Technology Equity Futures Rolling Strategy Series Q Total Return Index	GSISNQET	0%**	30%
Other Developed Market Equities	0%	50%	European Equity Futures Rolling Strategy Index	FRSIEUE	0%	30%

Commodities	0%	25%	Bloomberg Gold Subindex Total Return	BCOMGCTR	0%	25%
Cash Equivalent	0%	80%*	Return-Based Money Market Position	N/A	0%	80%*

* The base index asset class maximum weight and base index underlying asset maximum weight applicable to the Cash Equivalent in the table only apply to the return-based money market position in the base index, and not the deleverage cash position or the momentum risk control cash position (which are outside of the base index). As a result of the volatility control and momentum risk control adjustment features, the index may allocate nearly its entire exposure to hypothetical cash positions.

** Although the underlying asset weight of each of the US Large-Cap Equities (US Equity Futures Rolling Strategy Index) and US Technology Equities (US Technology Equity Futures Rolling Strategy Series Q Total Return Index) may be as low as 0%, their minimum combined weight must equal at least 20%.

     Selected Risk Factors

    

An investment in securities linked to the index is subject to the risks described below as well as the risks and considerations described in the accompanying MOBU Focus ER index supplement no. 13, the applicable pricing supplement, the applicable product supplement, if any, the accompanying prospectus supplement and the accompanying prospectus. The following risk factors are discussed in greater detail in the applicable pricing supplement and the accompanying MOBU Focus ER index supplement no. 13.

     Risks Related to the Index
▪The Index Measures the Performance of the Underlying Assets on an Excess Return Basis Less the Deduction Rate
▪Your Investment in the Securities May Be Subject to Concentration Risks. The assets underlying an eligible underlying asset may represent a particular market or commodity sector, a particular geographic region or some other sector or asset class. As a result, your investment in the securities may be concentrated in a single sector or asset class even though there are maximum weights for each base index underlying asset and each base index asset class.
▪You May Not Have Exposure to One or More of the Eligible Underlying Assets During the Term of the Securities
▪The Weight of Each Underlying Asset in the Base Index Reflects the Average of the Average of the Weights of Such Underlying Asset Over Three Look-Back Periods and Over the Weight Averaging Period
▪The Index May Not Successfully Capture Price Momentum
▪Base Index Asset Class Maximum Weights May in Many Cases Prevent All of the Eligible Base Index Underlying Assets in a Base Index Asset Class From Being Included in the Base Index at Their Base Index Underlying Asset Maximum Weights
▪The Index’s Exposure to the Performance of Underlying Indices May Be Limited by Deleveraging and the Weight and Volatility Constraints
▪The Lower Performance of One Underlying Asset May Offset an Increase in the Other Underlying Assets
▪Because Historical Returns and Realized Volatility Are Measured on an Aggregate Basis, the Index Could Include Eligible Underlying Assets With a High Realized Volatility and Could Exclude Eligible Underlying Assets With a High Historical Return
▪Correlation of Performances Among the Underlying Assets May Reduce the Performance of the Index
▪The Index May Have a Very Substantial Allocation to Hypothetical Cash Positions and Other Potentially Low-Yielding Assets on Any or All Days During the Term of the Securities
▪The Index’s Momentum Risk Control Adjustment Mechanism May Not Work as Intended and May Limit Returns
▪Base Index Allocations May Be Affected by the Methodology Algorithm
 
 

      

      
▪The Eligible Underlying Indices are Linked to Futures Strategies
▪Certain Eligible Underlying Assets are Subject to an Internal Currency Hedge, Which May Not be Effective
▪The Index May Perform Poorly During Periods Characterized by Increased Short-Term Volatility
▪Index Market Disruption Events Could Affect the Level of the Index on Any Date
▪The Index Has a Limited Operating History
▪The Historical Levels of the Notional Interest Rate Are Not an Indication of the Future Levels of the Notional Interest Rate
▪The Policies of the Index Sponsor, Index Committee and Index Calculation Agent, and Changes That Affect the Index or the Underlying Indices, Could Affect the Amount Payable on Your Securities and Their Market Value
▪The Index Calculation Agent Will Have Authority to Make Determinations that Could Affect the Value of Your Securities and the Amount You Receive at Maturity. The Goldman Sachs Group, Inc. Owns a Non-Controlling Interest in the Index Calculation Agent
▪As Index Sponsor, GS&Co. Can Replace the Index Calculation Agent at Any Time
▪The Index Calculation Agent Can Resign Upon Notification to the Index Sponsor
Additional Risks Related to the Eligible Underlying Indices
Risks related to eligible underlying indices comprised of futures contracts (including the US Equity Futures Rolling Strategy Index, the US Technology Equity Futures Rolling Strategy Series Q Total Return Index, the European Equity Futures Rolling Strategy Index, the Japanese Equity Futures Rolling Strategy Index, the US Government Bond Futures Rolling Strategy Index, the European Government Bond Futures Rolling Strategy Index, the Japanese Government Bond Futures Rolling Strategy Index, the Emerging Markets Equity Futures Rolling Strategy Index and the Bloomberg Gold Subindex Total Return)
▪Suspension or Disruptions of Market Trading in Futures Contracts Included in an Eligible Underlying Index May Adversely Affect the Level of the Index
▪Linking to a Futures Contract is Different From Linking to the Applicable Reference Equity Index or the Spot Price of the Applicable Physical Commodity
▪Negative Roll Yields Will Adversely Affect the Level of an Eligible Underlying Index Over Time and Therefore the Level of the Index

As a result, each such eligible underlying index is concentrated in the performance of bonds issued by a single issuer and having the same general tenor and terms.
Risks related to the US Technology Equity Futures Rolling Strategy Series Q Total Return Index
▪As Compared to Other Index Sponsors, Nasdaq, Inc. Retains Significant Control and Discretionary Decision-Making Over the Nasdaq-100 Index®, Which May Have an Adverse Effect on the Level of the Nasdaq-100 Index® and on Your Securities
