Sanofi U.S. Group Savings Plan

Morristown, New Jersey

Opinion on the Financial Statements

We have audited the accompanying statements of net assets available for benefits of the Sanofi U.S. Group Savings Plan (the “Plan”) as of December 31, 2024 and 2023, and the related statements of changes in net assets available for benefits for the years then ended, and the related notes (collectively referred to as the financial statements). In our opinion, the financial statements present fairly, in all material respects, the net assets available for benefits of the Plan as of December 31, 2024 and 2023, and the changes in net assets available for benefits for the years then ended, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements are the responsibility of the Plan’s management. Our responsibility is to express an opinion on the Plan’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Plan in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Plan is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Plan’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Supplemental Information

The supplemental information in the accompanying schedule of assets (held at end of year) as of December 31, 2024 has been subjected to audit procedures performed in conjunction with the audit of the Plan’s financial statements. The supplemental information is the responsibility of the Plan’s management. Our audit procedures included determining whether the supplemental information reconciles to the financial statements or the underlying accounting and other records, as applicable, and performing procedures to test the completeness and accuracy of the information presented in the supplemental information. In forming our opinion on the supplemental information, we evaluated whether the supplemental information, including its form and content, is presented in conformity with the Department of Labor’s Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. In our opinion, the supplemental information is fairly stated, in all material respects, in relation to the financial statements as a whole.

We have served as the Plan’s auditor since 2013.

Notes to the Financial Statements 

December 31, 2024 and 2023

The following description of the Sanofi U.S. Group Savings Plan (the “Plan”) provides only general information. Participants should refer to the Plan document for a more complete description of the Plan’s provisions.

Plan Description – The Plan is a defined contribution plan that covers substantially all employees of Sanofi U.S. Inc.; Sanofi U.S. LLC; Sanofi Pasteur Inc.; and Sanofi Genzyme (the “Company”), as they meet the prescribed eligibility requirements. All employees are eligible to participate in the Plan beginning on the first day of employment. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 (“ERISA”).

Plan Merger – Effective December 1, 2023, certain participant account balances of the Trinet 401(k) plan, sponsored by ProventionBio Inc., were transferred into the Plan. As a result of the transfer the Plan received total assets of $9,648,885, which are included within the Transfer in line on the Statement of Net Assets Available for Benefits.

Master Trust – Effective April 1, 2012, Sanofi U.S. LLC, Sanofi Pasteur Inc., Sanofi-Aventis Puerto Rico Inc. and T. Rowe Price Trust Company entered into an amended and restated Master Trust Agreement, and the Sanofi-Aventis U.S. Savings Master Trust was renamed the Sanofi U.S. Group Savings Master Trust (the “Master Trust”) to serve as the funding vehicle for the Plan. Accordingly, the assets of the Plan are maintained, for investment and administrative purposes only, on a commingled basis with the assets of the other plan within the employer’s parent company. The investments included within the Master Trust consist of equities, fixed income, mutual funds, common collective trusts, synthetic guaranteed investment contracts, and separate account contracts. The portion of assets, net earnings, gains and/or losses, and administrative expenses allocable to each plan is based upon the relationship of the plan’s interest in the Master Trust to the total interest of all plans in the Master Trust (Note 3).

Trustee and Recordkeeper – T. Rowe Price Trust Company is the Plan’s trustee (the “Trustee”). The Trustee is party to the Master Trust Agreement discussed above which governs and maintains the Plan’s commingled assets, as well as a general trust agreement for all other Plan operations. T. Rowe Price Retirement Plan Services Inc. is the Plan’s recordkeeper (Note 5).

Plan Administration – The Sanofi-Aventis U.S. Administrative Committee (the “Committee” or “Plan Administrator”), as appointed by the Sanofi-Aventis U.S. Pension Committee, is responsible for the general administration of the Plan. The Board of Directors has appointed the Trustee with the responsibility for the administration of the Master Trust Agreement and the management of the assets.

Employee Contributions – The Plan has an auto-enrollment feature whereby a participant is automatically enrolled in the Plan to make pre-tax contributions at 6% of eligible compensation unless the participant affirmatively opts out within a 30-day period from their date of hire. In addition, the Plan adopted an automatic election escalator feature whereby participants who were automatically enrolled will have their deferral rate increased each year by 1% until their deferral rate reaches 10%, unless the participant elects out of this treatment as prescribed by the Plan document. Eligible participants are allowed to contribute up to 75% of their eligible compensation as either pre-tax contributions, Roth contributions, or any combination of pre-tax and Roth contributions, and up to 10% in non-Roth after-tax contributions. Contributions are subject to certain Internal Revenue Code (“IRC”) limitations. IRC limitations for pre-tax and Roth contributions were $23,000 for 2024 and $22,500 for 2023. Employees 50 years old or older may make an additional catch-up contribution of up to $7,500 for both 2024 and 2023.

Notes to the Financial Statements 

December 31, 2024 and 2023

Plan participants may make a direct or indirect rollover contribution to the Plan from a former employer’s tax qualified plan. Participants can also rollover IRA distributions (excluding minimum required distributions and nondeductible contributions).

The Plan was amended effective October 1, 2018, to prohibit any further investment into the Company Stock Fund including future contributions, reallocations or transfers of existing account balances, dividends on Company Stock held in the Company Stock Fund, and loan repayments.

Employer Matching Contributions – The Company matching contribution is 150% of the pre-tax and/or Roth contributions for all participants, up to 6% of eligible compensation.

Participant Accounts – Each participant’s account is credited with the participants’ contributions, Company matching contributions, and Plan earnings. Participant accounts are charged with an allocation of administrative expenses and Plan losses. Allocations are based on participant earnings, account balances, or specific participant transactions, as defined. The benefit to which a participant is entitled is the benefit that can be provided from the participant’s vested account.

Upon enrollment into the Plan a participant may direct employee contributions into any of the Plan’s investment options. Participants may change their investment options at any time. If a participant does not make investment elections their contributions are defaulted to the age-appropriate target date fund within the year the participant would reach age 65. Company contributions are allocated in the same manner as that of the participant’s elective contributions.

Vesting – Effective April 1, 2012, all eligible employees hired on or before March 31, 2012 became 100% vested in their Company matching contribution account. Employees hired on or after April 1, 2012 will be 100% vested in their Company matching contribution account after two years of service. Participants are always 100% vested in their pre-tax, catch up, and after-tax contribution accounts (contributions and related earnings). Prior to April 1, 2012, employees who were participants on or before December 31, 2005 were 100% vested in their Company matching contribution account (contribution and related earnings), and employees hired on or after January 1, 2006 were 100% vested in their Company matching contribution account after three years of service.

Notes Receivable from Participants – Plan participants may borrow from $1,000 up to a maximum equal to the lesser of 50% of the value of their vested account balance or $50,000 less their highest outstanding loan balance in the preceding 12 months, subject to certain limitations described in the Plan document. Loans bear interest at a rate commensurate with the prevailing market rate, as determined by the Company. Currently, interest rates associated with participant loans range from 3.25% to 9.50%. Principal and interest are paid ratably though payroll deductions generally over a term of up to five years. A participant may not have more than two loans outstanding at any point in time. Extended terms of up to 15 years are available should the loan relate to the purchase of a primary residence.

Payment of Benefits – Plan participants who leave the Company as a result of death, disability, retirement, or termination may choose one or a combination of the following distribution methods: 1) receive the entire amount of their vested account balance in one lump-sum payment; 2) receive a partial distribution of the vested account balance; 3) receive the distribution in the form of recurring annual installments over a period of between three and fifteen years; 4) or, a combination of these methods. If a participant dies, the participant’s designated beneficiary will receive the payments.

In-service withdrawals are available in certain limited circumstances, as defined by the Plan.

Notes to the Financial Statements 

December 31, 2024 and 2023

Forfeitures – Forfeited non-vested accounts may be used to pay administrative expenses and/or off-set the amount of employer contributions, which are to be paid to the Plan. At December 31, 2024 and 2023, non-vested forfeited account balances totaled approximately $6,472,791 and $4,946,711, respectively. During the years ended December 31, 2024 and 2023, forfeited amounts of $14,365 and $1,797, respectively, were used to off-set employer matching contributions. During 2025, forfeitures of $7,740,917 were used to off-set the 2024 employer true up matching contribution to the Plan and during 2024, forfeitures of $6,450,000 were used to off-set the 2023 employer true up matching contribution to the Plan.

Administrative Budget – T. Rowe Price (“TRP”) will provide the Plan with funding for an administrative budget of $3.75 per participant quarterly ($15.00 annually), based on the total number of terminated participants, beneficiaries, and alternative payees with a balance in the Plan as of the last business day of each calendar quarter. The administrative budget shall be calculated on a quarterly basis after the end of each quarter and established as an account in the trust in accordance with directions provided by the Company. The administrative budget may be used to pay certain administrative expenses of the Plan, as directed by the Plan's named fiduciary, as defined in Section 402(a)(2) of ERISA. Any amounts credited to the administrative budget and not used in the year so credited shall be allocated as determined by the named fiduciary. For the Plan years 2024 and 2023, TRP contributed $268,129 and $378,158, respectively, to the Plan’s administrative budget account. During 2024 and 2023, the Plan used $167,064 and $254,195, respectively, of the administrative budget to off-set Plan expenses. In addition, during 2024 and 2023, amounts totaling $-0- and $395,431, respectively, were allocated to participant accounts. As of December 31, 2024 and 2023, the balances of the administrative budget accounts were $200,147 and $87,909, respectively. Included within the year end balances are revenue sharing contribution receivables of $50,632 for 2024 and $50,749 for 2023 and amounts payable (included in accrued administrative expenses) from the administrative budget account of $96,500 for both years.

Basis of Accounting – The financial statements of the Plan have been prepared in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP).

Use of Estimates – The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and changes therein, and disclosure of contingent assets and liabilities. Actual results could differ from those estimates.

Investment Valuation – For investment and administrative purposes the Plan’s assets are held within the custody of the Master Trust. The Plan’s investment in the Master Trust represents the Plan’s interest in the net assets of the Master Trust. The Plan’s interest in the Master Trust is stated at fair value, except for fully benefit-responsive investment contracts (“FBRICs”) which are reported at contract value, and is based on the beginning of year value of the Plan’s interest in the trust plus actual contributions and allocated investment income or loss less actual distributions and allocated administrative expenses.

The Stable Value Fund (see Note 3) is a FBRIC and is therefore measured at contract value. Contract value is the relevant measurement attribute for that portion of the net assets available for benefits of a defined contribution plan attributable to fully benefit-responsive investment contracts because contract value is the amount participants would receive if they were to initiate permitted transactions under the terms of the plan.

Sanofi U.S. Group Savings Plan

Notes to the Financial Statements 

December 31, 2024 and 2023

Notes Receivable from Participants – Notes receivable from participants represent loans recorded at their unpaid principal balance plus accrued interest. Interest income generated on the notes receivable is recorded when earned. Related fees are recorded as administrative expenses and are expensed when they are incurred. The loans are secured by the vested balance in the participant accounts. If a participant ceases to make loan repayments and the Plan Administrator deems the participant loan to be in default based on Plan provisions, the participant loan balance is reduced and a benefit payment is recorded.

Payment of Benefits – Benefit payments to participants are recorded when paid.

Fees and Administrative Expenses − All external third-party expenses and internal expenses relating to the administration of the Master Trust and managing the funds established thereunder are borne by the participating plans, unless they are paid by the Company. Brokerage commissions, transfer taxes and other charges incurred in connection with the purchase and sale of securities are paid out of the funds to which such charges are attributable.

Risks and Uncertainties – The Plan provides for various investment options representing varied combinations of stocks, bonds, fixed income securities, mutual funds and other investment securities. Investment securities are exposed to various risks, such as interest rate, market volatility and credit risks. Due to the level of risk associated with certain investment securities, it is at least reasonably possible that changes in the values of investment securities will occur in the near term and that such changes could materially affect participants’ account balances and the amounts reported in the Statement of Net Assets available for Benefits.

The Master Trust comprises the investment assets of the Plan and the Sanofi Puerto Rico Group Savings Plan. Certain investment assets of the Master Trust, related earnings (losses), and expenses are allocated to all the plans that participate in the Master Trust based upon the total of each individual participant’s share of the Master Trust.

At December 31, 2024 and 2023, the Plan’s interest in the Master Trust was approximately 99% of the total trust.

The following tables present the investments and other assets and changes in net assets of the Sanofi U.S. Group Savings Master Trust, and the Plan, as of and for the years December 31, 2024 and 2023:

Investment Valuation and Income Recognition – The investments of the Master Trust are reported at fair value, except for the Stable Value Fund which is a FBRIC and is required to be reported at contract value. Purchases and sales of investments within the Master Trust are recorded on the trade-date basis (the day the order to buy or sell is executed). Interest income is recorded on the accrual basis, and dividend income is recorded on the ex-dividend date.

Fair Value Measurements – The accounting guidance defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (i.e., an exit price). The fair value hierarchy prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets and liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The three levels of the fair value hierarchy are described below:

Sanofi U.S. Group Savings Plan

Notes to the Financial Statements 

December 31, 2024 and 2023

Level 1: Inputs to the valuation methodology are unadjusted quoted prices for identical assets or liabilities in active markets that the Plan has the ability to access.

Level 2: Inputs to the valuation methodology include:

If the asset or liability has a specified (contractual) term, the Level 2 input must be observable for substantially the full term of the asset or liability.

Level 3: Inputs to the valuation methodology are unobservable and significant to the fair value measurement. Level 3 inputs include management’s own assumption about the assumptions that market participants would use in pricing the asset or liability (including assumptions about risk).

The asset’s or liability’s fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. The valuation technique used needs to maximize the use of observable inputs and minimize the use of unobservable inputs.

Following is a description of the valuation methodologies used for assets measured at fair value. There have been no changes in the methodologies used at December 31, 2024 and 2023. All of the Plan’s assets are invested in the Master Trust.

Self-Directed Brokerage Accounts – These accounts consist of over-the-counter publicly traded mutual funds that are valued using quoted market prices of the underlying investments as reported in the active market in which the mutual funds are traded. They are classified within Level 1 of the valuation hierarchy.

Common Collective Trust Funds – These funds are investment vehicles consisting of target date funds, index funds, international equity and fixed income funds, and a U.S. Treasury money market trust. Units held in common collective trust funds are valued at the net asset value (“NAV”) as a practical expedient as determined by the issuer based on the current fair values of the underlying assets of the fund. Investments that use NAV as a practical expedient to measure fair value have not been classified in the fair value hierarchy in accordance with Accounting Standards Codification (“ASC”) Subtopic 820-10.

Separately Managed Accounts – These investments are individually managed investment accounts that are managed by various investment advisors. The underlying investments of the accounts include domestic equities including Company stock, corporate and governmental fixed income securities, and short-term investments. The units held of separately managed accounts are valued at the NAV, as a practical expedient, as determined by the issuers based on the current fair values of the underlying assets of the separately managed accounts, including any receivables or payables applicable to the fund. Investments that use NAV as a practical expedient to measure fair value have not been classified in the fair value hierarchy in accordance with ASC Subtopic 820-10.

Sanofi U.S. Group Savings Plan

Notes to the Financial Statements 

December 31, 2024 and 2023

Company stock held within a separately managed account is valued at the closing price reported on the active market on which the individual securities are traded. This investment is classified within Level 1 of the valuation hierarchy.

The methods described above may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, while the Plan believes its valuation methods are appropriate and consistent with ASC 820 guidance, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date.

The availability of observable market data is monitored to assess the appropriate classification of financial instruments within the fair value hierarchy. Changes in economic conditions or model-based valuation techniques may require the transfer of financial instruments from one fair value level to another. In such instances, the transfer is reported at the end of the reporting period.

The following tables set forth by level, within the fair value hierarchy, the Master Trust assets at fair value as of December 31, 2024 and 2023:

Investments Measured at NAV – The following tables summarize investments for which fair value is measured using the net asset value per share practical expedient as of December 31, 2024 and 2023. There are no participating redemption restrictions for these investments; the redemption notice period is applicable only to the Master Trust.

Sanofi U.S. Group Savings Plan

Notes to the Financial Statements 

December 31, 2024 and 2023

Fully Benefit-Responsive investment Contracts (“FBRIC”) – The Master Trust entered into fully benefit-responsive investment contracts in the Stable Value Fund that invest primarily in investment contracts issued by high-quality insurance companies and banks as rated by T. Rowe Price Associates, Inc. These contracts meet the fully benefit-responsive contract criteria and therefore are reported at contract value. Contract value is the relevant measure for FBRICs because this is the amount received by participants if they were to initiate permitted transactions under the terms of the Plan. These are interest bearing contracts in which the principal and interest are guaranteed by the issuing companies. Contract value represents contributions made to the investment contracts plus earnings, less participant withdrawals and administrative expenses.

The Stable Value Fund invests in synthetic guaranteed investment contracts (“SICs”) and separate account contracts. For investments in SICs, the Master Trust owns the underlying investments, whereas for investments in the separate account contracts, the Master Trust receives title to the annuity contract, but not the direct title to the assets in the separate account. SICs and separate account contracts are generally backed by fixed income assets. The underlying investments wrapped within the SICs and separate account contracts are managed by third party fixed income managers and include securities diversified across the broad fixed income market, such as, but not limited to, corporate bonds, mortgage related securities, government bonds, asset-backed securities, cash, and cash equivalents.

SICs, backed by underlying assets, are designed to provide principal protection and accrued interest over a specified period of time through benefit-responsive wrapper contracts issued by a third party assuming that the underlying assets meet the requirements of the SIC. Separate account contracts are investment contracts invested in insurance company separate accounts established for the sole benefit of the Stable Value Fund included within the Master Trust. SICs and separate account contracts are wrapped by the financially responsible insurance company.

Sanofi U.S. Group Savings Plan

Notes to the Financial Statements 

December 31, 2024 and 2023

The issuers of the SICs and separate account contracts are contractually obligated to repay the principal and a specified interest rate that is guaranteed to the Master Trust. The fund deposits a lump sum with the issuer and receives a guaranteed interest rate for a specified time. There are currently no reserves against contract values for credit risk of the contract issuers or otherwise and do not permit the insurance companies to terminate the agreement prior to the scheduled maturity date. Each contract is subject to early termination penalties that may be significant.

The crediting rates for SICs and separate account contracts are periodically reset during the year and are based on the performance of the contract’s underlying assets. Interest is accrued on either a simple interest or fully compounded basis and paid either periodically or at the end of the contract term. The average crediting rate for the investment contracts was 3.39% and 3.16% for 2024 and 2023, respectively.

Certain events could limit the ability of the Master Trust to transact at contract value with the issuer. Such events include the following: (i) amendments to the Plan documents (including complete or partial plan termination or merger with another plan); (ii) changes to the Plan’s prohibition on competing investment options or deletion of equity wash provisions; (iii) bankruptcy of the Plan sponsor or other plan sponsor events (e.g. divestures or spin-offs of a subsidiary) which cause a significant withdrawal from the Plan or (iv) the failure of the trust to qualify for exemption from federal income taxes or any required prohibited transaction exemption under ERISA. The Plan Administrator does not believe that the occurrence of any such event, which would limit the Plan’s ability to transact at contract value with participants, is probable.

Participant-directed redemptions have no restrictions; however, the Plan is required to provide a one-year redemption notice to liquidate its entire interest in the fund.

The following represents the disaggregation of contract value between types of investment contracts held by the Master Trust for the FBRIC at December 31, 2024 and 2023:

The Internal Revenue Service (“IRS”) has determined and informed the Company by a letter dated July 24, 2015, that the Plan and related trust are designed in accordance with applicable sections of the IRC. In December 2016, the IRS began publishing a Required Amendments List for individually designed plans that specifies changes in qualification requirements. The list is published annually and requires plans to be amended for each item on the list, as applicable, to retain the Plan’s tax exempt status. The Plan has been amended since receiving the determination letter, however, the Plan Administrator and the Plan’s tax counsel believe that the Plan is designed, and is currently being operated, in compliance with the applicable requirements of the IRC and, therefore, believe that the Plan is qualified, and the related trust is tax-exempt.

Sanofi U.S. Group Savings Plan

Notes to the Financial Statements 

December 31, 2024 and 2023

Accounting principles generally accepted in the United States of America require Plan management to evaluate tax positions taken by the Plan and recognize a tax liability if the organization has taken an uncertain position that more likely than not would not be sustained upon examination by the applicable taxing authorities. The Plan is subject to routine audits by taxing jurisdictions; however, there are currently no audits for any tax periods in progress.

Certain Master Trust investments are shares of mutual funds managed by T. Rowe Price Trust Company, the trustee of the Plan. T. Rowe Price Retirement Plan Services Inc. is the recordkeeper of the Plan. Therefore, these transactions qualify as party-in-interest transactions.

The Master Trust invests in shares of the parent company, Sanofi, through the Sanofi-US ADR Fund (the “fund”); therefore, these transactions qualify as party-in-interest transactions. As of October 5, 2018, the “fund” was transitioned to individual share accounting at the direction of the Plan sponsor.

During the year ended December 31, 2024, the Master Trust made purchases of $-0-, sales of approximately $4,146,229, realized gains of $40,279, and dividend income of $1,631,140 earned from the investment in the Company’s common stock. The total shares and market value of the company stock held by the Master Trust at December 31, 2024 were 881,132 and $42,496,960, respectively. During the year ended December 31, 2023, the Master Trust made purchases of $-0-, sales of approximately $4,993,336, realized gains of $421,926, and dividend income of $1,712,492 earned from the investment in the Company’s common stock. The total shares and market value of the company stock held by the Master Trust at December 31, 2023 were 1,020,355 and $50,742,243, respectively.

Certain administrative fees have been paid through a revenue sharing agreement with T. Rowe Price Retirement Plan Services Inc. rather than direct payments and qualify as party-in-interest transactions.

In addition, certain Plan participants borrowed from the Plan. As of December 31, 2024 and 2023, the outstanding loans of the Plan participants were $44,961,037 and $43,087,391, respectively (refer to Note 1 for applicable interest rates). Loans to participants also qualify as party-in-interest transactions.

All of the above transactions are not considered prohibited transactions pursuant to the prohibited transaction rules of the Department of Labor and Section 408 of ERISA.

Although it has not expressed any intent to do so, the Company has the right under the Plan to discontinue its contributions at any time and to terminate the Plan subject to the provisions of ERISA. Upon such termination of the Plan, the interest of each participant in the trust fund will be distributed to such participant or his or her beneficiary at the time prescribed by the Plan terms and the Code. In the event of Plan termination, participants would become 100% vested in their employer contributions.

Plan management has evaluated all subsequent events through June 27, 2025, the date the financial statements were issued.

No significant subsequent events were noted.
