Exhibit 99.1
1. Condensed half-year consolidated financial statements
Notes to the condensed half-year consolidated financial statements as of June 30, 2025
(Unaudited(1))
Introduction
Sanofi, together with its subsidiaries (collectively “Sanofi”, “the Group” or “the Company”), is a global healthcare leader engaged in the research, development and marketing of therapeutic solutions focused on patient needs.
Sanofi is listed in Paris (Euronext: SAN) and New York (Nasdaq: SNY).
The condensed consolidated financial statements for the six months ended June 30, 2025 were reviewed by the Sanofi Board of Directors at the Board meeting on July 30, 2025.
A/ Basis of preparation of the half-year financial statements and accounting policies
A.1. International financial reporting standards (IFRS)
The half-year consolidated financial statements have been prepared and presented in condensed format in accordance with IAS 34 (Interim Financial Reporting). The accompanying notes therefore relate to significant events and transactions of the period, and should be read in conjunction with the consolidated financial statements for the year ended December 31, 2024.
The accounting policies used in the preparation of the consolidated financial statements as of June 30, 2025 comply with international financial reporting standards (IFRS) as endorsed by the European Union and as issued by the International Accounting Standards Board (IASB). IFRS as endorsed by the European Union as of June 30, 2025 are available via the following web link:
https://www.efrag.org/Endorsement
The accounting policies applied effective January 1, 2025 are identical to those presented in the consolidated financial statements for the year ended December 31, 2024.
On August 15, 2023, the IASB issued "Lack of Exchangeability", an amendment to IAS 21 (The Effects of Changes in Foreign Exchange Rates), relating to how to determine the exchange rate when a currency is not exchangeable. The amendment became applicable on January 1, 2025, and does not have a material impact on the Sanofi financial statements.
In its 2025 half-year financial statements, Sanofi has used an average effective tax rate that takes into account the Pillar Two top-up tax applicable from January 1, 2024. The effective tax rate also includes a one-off impact from the 2024 component of the exceptional contribution in respect of French corporate income taxes (see Note B.19.).
A.2. Use of estimates and judgments
The preparation of financial statements requires management to make reasonable estimates and assumptions based on information available at the date the financial statements are finalized. Those estimates and assumptions may affect the reported amounts of assets, liabilities, revenues and expenses in the financial statements, and disclosures of contingent assets and contingent liabilities as of the date of the review of the financial statements. Examples of estimates and assumptions include:
•amounts deducted from sales for projected sales returns, chargeback incentives, rebates and price reductions;
•impairment of property, plant and equipment and intangible assets;
•the valuation of goodwill and the valuation and useful life of acquired intangible assets;
•the measurement of contingent consideration receivable in connection with asset divestments and of contingent consideration payable;
•the measurement of financial assets and financial liabilities at amortized cost;
•the amount of post-employment benefit obligations;
•the amount of liabilities or provisions for restructuring, litigation, tax risks relating to corporate income taxes, and environmental risks; and
•the amount of deferred tax assets resulting from tax losses available for carry-forward and deductible temporary differences.
Actual results could differ from these estimates.
For half-year financial reporting purposes, and as allowed under IAS 34, Sanofi has determined income tax expense on the basis of an estimate of the effective tax rate for the full financial year. That rate is applied to business operating income plus financial income and minus financial expenses, and before (i) the share of profit/loss of investments accounted for using the equity method and (ii) net income attributable to non-controlling interests. The estimated full-year effective tax rate is based on the tax rates that will be applicable to projected pre-tax profits or losses arising in the various tax jurisdictions in which Sanofi operates.
(1) These unaudited condensed half year consolidated financial statements as of June 30, 2025 should be read in conjunction with Sanofi’s audited consolidated financial statements as of December 31, 2024.

In 2025, Sanofi continues to account for subsidiaries based in Venezuela using the full consolidation method, on the basis that the criteria for control as specified in IFRS 10 (Consolidated Financial Statements) are still met. The contribution of the Venezuelan subsidiaries to the consolidated financial statements is immaterial.
In Argentina, the cumulative rate of inflation over the last three years is in excess of 100%, based on a combination of indices used to measure inflation in that country. Consequently, Sanofi has (since July 1, 2018) treated Argentina as a hyperinflationary economy and has applied IAS 29. The impact of the resulting restatements is immaterial at Sanofi group level.
In Turkey, the cumulative rate of inflation over the last three years is in excess of 100%, based on a combination of indices used to measure inflation in that country. Consequently, Sanofi has (since January 1, 2022) treated Turkey as a hyperinflationary economy and has applied IAS 29. The impact of the resulting restatements is immaterial at Sanofi group level.
A.5. Fair value of financial instruments
Under IFRS 13 (Fair Value Measurement) and IFRS 7 (Financial Instruments: Disclosures), fair value measurements must be classified using a hierarchy based on the inputs used to measure the fair value of the instrument. This hierarchy has three levels:
•Level 1: quoted prices in active markets for identical assets or liabilities (without modification or repackaging);
•Level 2: quoted prices in active markets for similar assets or liabilities, or valuation techniques in which all important inputs are derived from observable market data; and
•Level 3: valuation techniques in which not all important inputs are derived from observable market data.

The fair value of contingent consideration receivable is determined by adjusting the contingent consideration at the end of the reporting period using the method described in Note D.7.3. to the consolidated financial statements for the year ended December 31, 2024.

B.6. Long-term loans and advances and other non-current receivables Amortized cost N/A N/A The amortized cost of long-term loans and advances and other non-current receivables at the end of the reporting period is not materially different from their fair value.

Financial liabilities
Amortized cost (a)
N/A N/A In the case of financial liabilities with a maturity of less than 3 months, amortized cost is regarded as an acceptable approximation of fair value as reported in the notes to the consolidated financial statements.
For financial liabilities with a maturity of more than 3 months, fair value as reported in the notes to the consolidated financial statements is determined either by reference to quoted market prices at the end of the reporting period (quoted instruments) or by discounting the future cash flows based on observable market data at the end of the reporting period (unquoted instruments).
For financial liabilities based on variable payments such as royalties, fair value is determined on the basis of discounted cash flow projections.
B.9. Lease liabilities Amortized cost N/A N/A Future lease payments are discounted using the incremental borrowing rate.

A.6. New pronouncements issued by the IASB and applicable from 2026
On April 9, 2024, the IASB issued IFRS 18 (Presentation and Disclosure in Financial Statements), applicable from January 1, 2027 (subject to endorsement by the European Union). An impact assessment is currently under way. Sanofi will not early adopt this new standard.
On May 30, 2024, the IASB issued amendments to IFRS 9 and IFRS 7 relating to the classification and measurement of financial instruments, applicable no earlier than January 1, 2026. Sanofi does not expect any material impact, and will not early adopt these amendments.
On July 18, 2024, the IASB issued Volume 11 of “Annual Improvements to IFRS”, applicable from January 1, 2026. Sanofi does not expect any material impact from those improvements to various standards, which are essentially in the nature of clarifications, and will not early adopt them.
On December 18, 2024, the IASB issued "Contracts referencing nature-dependent electricity", amendments to IFRS 9 and IFRS 7, applicable from January 1, 2026. The amendments clarify the application of the ‘own use’ exemption to Power Purchase Agreements (PPAs) with physical delivery of renewable electricity, and modify the hedge accounting requirements for contracts without physical delivery (VPPAs). Sanofi does not expect any material impact and will not early adopt these amendments. Renewable energy purchase contracts entered into by Sanofi as of December 31, 2024 are described in Note D.21. to the consolidated financial statements included in the 2024 Form 20-F for the year ended December 31, 2024 (the “2024 20-F”).

B/ Significant information for the first half of 2025
B.1. Significant transactions for the first half of 2025
B.1.1. Opella - Loss of control and equity interest in OPAL JV Co
On April 30, 2025, Sanofi and CD&R closed the Opella transaction following the signature of the share purchase agreement (SPA) on February 18, 2025. Sanofi retains a significant shareholding in Opella, through a 48.2% equity interest in OPAL JV Co (formed in Luxembourg), which indirectly holds 100% of Opella. Bpifrance owns a 1.8% equity interest, and is represented on Opella’s Board.
Completion of the deal resulted in the loss of control of Opella by Sanofi and the derecognition of Opella’s assets and liabilities. This resulted in a net gain of €2.7 billion, reported within the line item Net income from discontinued operations in the consolidated income statement. The proceeds from the divestment of Opella, determined on the basis of a €16 billion enterprise value, reflected the estimated share price. That price is subject to adjustments following finalization of the Opella completion accounts, expected at the earliest in the fourth quarter of 2025.
As of the closing date of the transaction, the carrying amount of Opella’s assets and liabilities in the Sanofi consolidated balance sheet was €11.3 billion.
The gain took into account the following components: (i) a reclassification of unrealized foreign exchange losses amounting to €0.5 billion associated with Opella operations, in accordance with IAS 21 (“The Effects of Changes in Foreign Exchange Rates”); (ii) recognition of the retained 48.2% equity interest in OPAL JV Co (over which Sanofi exercises significant influence as defined in IAS 28 “Investments in Associates and Joint Ventures”), reported within the balance sheet line item Investments accounted for using the equity method at an amount of €3.2 billion (representing the fair value of the equity interest at the date of initial recognition in accordance with IFRS 10 and included in the estimated share price, plus capitalized transaction costs); and (iii) other items, mainly comprising compensation as agreed under the separation agreements.
The Opella transaction generated a net cash inflow of €10.7 billion, presented within the line item Net cash inflow from the Opella transaction in the statement of cash flows.
As a reminder, on October 21, 2024, Sanofi and CD&R entered into exclusive negotiations for the transfer of a controlling interest in Opella. As of December 31, 2024, completion of the transaction was considered highly probable. In accordance with the classification and presentation requirements of IFRS 5 (see Note B.7. to the consolidated financial statements for the year ended December 31, 2024), all assets of Opella and all liabilities directly related to those assets were classified from October 21, 2024 in the line items Assets held for sale and Liabilities related to assets held for sale, respectively, in the consolidated balance sheet (see Notes D.8. and D.36. to the consolidated financial statements for the year ended December 31, 2024). Opella (formerly known as Consumer Healthcare) constituted an operating segment of Sanofi until October 21, 2024 (see Note D.35., "Segment Information" to the consolidated financial statements for the year ended December 31, 2024). Consequently, Opella met the definition of a discontinued operation under IFRS 5 (see Note B.7. to the consolidated financial statements for the year ended December 31, 2024), as a result of which the net income from that business was presented separately within the line item Net income from discontinued operations in the consolidated income statement. This presentation in a separate income statement line item applied to operations for the year ended December 31, 2024, and on a consistent basis for the comparative periods presented. The cash flows arising from operating, investing and financing activities of the Opella business were also presented in separate line items in the consolidated statements of cash flows for the year ended December 31, 2024 and for the comparative periods presented.

B.1.2. Acquisition of Dren-0201, Inc.
On May 27, 2025, Sanofi announced the completion of the acquisition of 100% of Dren-0201, Inc., adding SAR448501 (formerly DR-0201) to Sanofi’s immunology pipeline. DR-0201, now named SAR448501, has shown robust B-cell depletion in pre-clinical and early clinical studies. This potential first-in-class targeted bispecific myeloid cell engager targets and engages specific tissue-resident and trafficking myeloid cells to induce deep B-cell depletion via targeted phagocytosis. Recent pre-clinical and early clinical study data in autoimmune diseases suggest that deep B-cell depletion has the potential to reset the adaptive immune system, leading to sustained treatment-free remission in patients with refractory B-cell mediated autoimmune diseases such as lupus, where significant unmet medical needs remain.
The transaction did not meet the criteria for a business combination under IFRS 3, and consequently was accounted for as an acquisition of a group of assets.
The acquisition price was $600 million. Of that amount (plus acquisition-related costs), $562 million was allocated to in-process development in respect of SAR448501, and recognized within Other intangible assets in accordance with IAS 38. The difference between that amount and the acquisition price corresponds to the other assets acquired and liabilities assumed in the transaction.
In addition, potential future payments totalling $1.3 billion contingent on attainment of certain development and launch milestones have been recognized as off balance sheet commitments. These milestones will be added to the value of the SAR448501 intangible asset if and when attained.
The impact of this acquisition, as reflected within the line item Acquisitions of consolidated undertakings and investments accounted for using the equity method in the consolidated statement of cash flows, is a net cash outflow of $602 million.
B.1.3. Agreed transactions expected to be finalized in the second half of 2025
Acquisition of Vigil Neuroscience, Inc.
On May 22, 2025, Sanofi announced that it had entered into an agreement to acquire Vigil Neuroscience, Inc. (“Vigil”), a publicly traded clinical-stage biotechnology company focused on developing novel therapies for neurodegenerative diseases. This acquisition in neurology, one of Sanofi’s four strategic disease areas, enhances Sanofi’s early-stage pipeline and includes VG-3927, which will be evaluated in a phase 2 clinical study in Alzheimer’s disease. VG-3927 is an oral small molecule TREM2 agonist. Activating TREM2 is expected to enhance the neuroprotective function of microglia in Alzheimer’s disease.
Under the terms of a share purchase agreement (including the exclusive right of first negotiation for an exclusive license to VG-3927 or for transfer of the rights to research, develop, manufacture, and commercialize VG-3927) entered into by Sanofi and Vigil in June 2024 for an amount of $40 million, Sanofi already held an equity interest in Vigil Neuroscience, Inc., representing approximately 12% of Vigil’s share capital. That equity interest was remeasured at market value as at June 30, 2025 through Other comprehensive income.
VGL101, Vigil’s second molecule program, is not being acquired by Sanofi.
Sanofi will acquire all outstanding common shares of Vigil for $8.00 per share in cash at closing. Based on $8.00 per share, the total equity value of Vigil represents approximately $470 million (on a fully diluted basis).
In addition, Vigil’s shareholders will receive one non-transferable and non-tradeable contractual contingent value right (CVR) per Vigil share entitling the holder to receive a deferred cash payment of $2.00, contingent upon the first commercial sales of VG-3927.
The acquisition is expected to close in the third quarter of 2025 subject to closing conditions.
Acquisition of Blueprint Medicines Corporation
On June 2, 2025, Sanofi and Blueprint Medicines Corporation (Blueprint), a US-based, publicly traded biopharmaceutical company specializing in systemic mastocytosis (SM), a rare immunological disease, and other KIT-driven diseases, entered into an agreement under which Sanofi agreed to acquire Blueprint.
The acquisition included a rare immunology disease medicine, Ayvakit/Ayvakyt (avapritinib), approved in the US and the EU, and a promising advanced and early-stage immunology pipeline. Blueprint’s established presence among allergists, dermatologists, and immunologists is expected to enhance Sanofi’s growing immunology pipeline.
Under the terms of the acquisition, Sanofi agreed to pay $129.00 per share in cash at closing, representing an equity value of approximately $9.1 billion for 100% of the shares. Blueprint shareholders also received one non-tradable contractual contingent value right (CVR) per share which entitles the holder to receive two potential milestone payments of $2.00 and $4.00 per CVR on the attainment of future development and regulatory milestones within the applicable milestone period, respectively, for BLU-808. The total equity value of the transaction, including potential CVR payments, represents approximately $9.5 billion on a fully diluted basis.
In July 2025, Sanofi obtained control of Blueprint after all tender offer and merger conditions had been met.

A total of 171,150 shares were issued in the first half of 2025 as a result of the exercise of Sanofi stock subscription options.
In addition, 2,682,051 shares vested under Sanofi restricted share plans during the first half of 2025, of which 1,156,205 were fulfilled by issuance of new shares and 1,525,846 by allotment of existing shares free of charge.
B.8.2. Repurchase of Sanofi shares
On April 30, 2024, the Annual General Meeting of Sanofi shareholders authorized a share repurchase program for a period of 18 months. Under that program, Sanofi repurchased 39,344,633 of its own shares during the first half of 2025 for a total amount of €3,988 million.
During the meeting of the Board of Directors on January 29, 2025, the Board authorized Sanofi to repurchase the Company's shares, for an amount not exceeding €5 billion, under the terms and conditions set by the General Meeting of April 30, 2024 in its 19th resolution. As part of this authorization, Sanofi entered into a share buyback agreement with its historical shareholder L'Oréal on February 2, 2025 for the acquisition of 2.34% of Sanofi’s share capital, equivalent to 29,556,650 shares, for a total amount of approximately €3 billion, representing a price of €101.50 per share. The conclusion of that agreement was approved by the Board of Directors on the same day prior to the signing of the agreement, and in accordance with the procedure set forth in Articles L. 225-38 et seq. of the French Commercial Code.
On April 30, 2025, the Annual General Meeting of Sanofi shareholders authorized a share repurchase program for a period of 18 months. Sanofi did not use that authorization during the first half of 2025.
B.8.3. Reduction in share capital
During the first half of 2025, treasury shares amounting to €3,868 million were cancelled further to decisions taken by the Sanofi Board of Directors on March 13, 2025 and April 23, 2025.

i.March 2025: a bond issue of €1.5 billion in two tranches:
• €850 million of floating-rate bonds maturing March 2027, with quarterly coupons and bearing interest at an annual rate of 3-month Euribor plus 30 basis points; and
• €650 million of fixed-rate bonds maturing March 2031, with annual coupons and bearing interest at an annual rate of 2.750%.
ii.June 2025: a bond issue of €1.5 billion in two tranches:
• €750 million of fixed-rate bonds maturing June 2029, with annual coupons and bearing interest at an annual rate of 2.625%; and
• €750 million of fixed-rate bonds maturing June 2032, with annual coupons and bearing interest at an annual rate of 3.000%.
Two bond issues were redeemed in 2025:
i.the €1 billion fixed-rate bond issue from April 2020, which was redeemed at maturity on April 1, 2025; and
ii.the €850 million fixed-rate bond issue from April 2022, which was redeemed at maturity on April 6, 2025.
As of June 30, 2025, Sanofi had two syndicated credit facilities linked to social and environmental criteria in place to manage its liquidity in connection with current operations:
i.a syndicated credit facility of €4 billion, drawable in euros and US dollars and expiring on December 6, 2027, for which no further extension options are available; and
ii.a syndicated credit facility of €4 billion, drawable in euros and US dollars and expiring on March 6, 2030, for which no further extension options are available.
As of June 30, 2025, neither facility was drawn down.
Sanofi also has two short-term debt programs:
i.a €6 billion Negotiable European Commercial Paper program in France; and
ii.a $10 billion Commercial Paper program in the United States.
During the first half of 2025:
i.the average drawdown under the US Commercial Paper program was $2.63 billion; and
ii.the average drawdown under the Negotiable European Commercial Paper program in France was €0.02 billion.
The financing in place as of June 30, 2025 at the level of the holding company (which manages most of Sanofi’s financing needs centrally) is not subject to any financial covenants, and contains no clauses linking credit spreads or fees to the credit rating.
B.9.2. Market value of net debt
The market value of Sanofi’s debt, net of cash and cash equivalents and derivatives and excluding accrued interest, is as follows:

The above positions mainly hedge material foreign currency cash flows arising after the end of the reporting period in relation to transactions carried out during the six months ended June 30, 2025 and recognized in the balance sheet at that date. Gains and losses on hedging instruments (forward contracts) are calculated and recognized in parallel with the recognition of gains and losses on the hedged items. Due to this hedging relationship, the commercial foreign exchange difference on those items (hedging instruments and hedged transactions) will be immaterial in the second half of 2025.
B.10.2. Currency and interest rate derivatives used to manage financial exposure
The cash pooling arrangements for foreign subsidiaries outside the eurozone, and some of Sanofi’s financing activities, expose certain Sanofi entities to financial foreign exchange risk (i.e. the risk of changes in the value of loans and borrowings denominated in a currency other than the functional currency of the lender or borrower).
That foreign exchange exposure is hedged using derivative instruments (currency swaps or forward contracts) that alter the currency split of Sanofi’s debt once those instruments are taken into account.
The table below shows financial currency hedging instruments in place as of June 30, 2025. The notional amount is translated into euros at the relevant closing exchange rate.

As of June 30, 2025, the fair value of the swaps was an asset of €5 million, with €18 million debited to Other comprehensive income under the cost of hedging accounting treatment.

(b)Includes forward sales with a notional amount of $3,615 million expiring in 2025, designated as a hedge of Sanofi’s net investment in Bioverativ. As of June 30, 2025, the fair value of these forward contracts represented an asset of €77 million; the opposite entry was recognized in Other comprehensive income, with the impact on financial income and expense being immaterial.
(c)    Includes forward purchases with a notional amount of $1,000 million expiring in 2025, designated as a fair value hedge of the exposure of $1,000 million of bond issues to fluctuations in the EUR/USD spot rate. As of June 30, 2025, the fair value of these contracts represented a liability of €25 million, with €0 million credited to Other comprehensive income to recognize the hedging cost.

To optimize the cost of debt or reduce the volatility of debt, Sanofi uses derivative instruments (interest rate swaps and cross currency swaps) to alter the fixed/floating rate split of its net debt.

(b    Amounts mainly reported within the income statement line item “Fair value remeasurement of contingent consideration”.
As of June 30, 2025, Liabilities related to business combinations and to non-controlling interests mainly comprised the contingent consideration liability towards Shire Human Genetic Therapies Inc. (Shire) arising from Sanofi's acquisition of Translate Bio in September 2021. The fair value of the Shire liability is determined by applying the contractual terms to development and sales projections that are weighted to reflect the probability of success, and discounted. The liability was measured at €563 million as of June 30, 2025, compared with €568 million as of December 31, 2024. If the discount rate were to fall by one percentage point, the fair value of the Shire liability would increase by approximately 10%.
The MSD contingent consideration liability arising from the 2016 acquisition of the Sanofi Pasteur activities carried on within the former Sanofi Pasteur MSD joint venture was extinguished during 2024 in accordance with the contractual terms. Sanofi has no further liability in respect of this contingent consideration following settlement of the milestone linked to 2024 sales.

Given the method used to calculate royalties payable, an increase or decrease in sales forecasts would lead to a proportionate change in the amount of the liability. The nominal value of payments estimated to be due within more than one year but less than five years is €1,027 million; the nominal value of payments estimated to be due after more than five years is €2,293 million.

Provisions for pensions and other post-employment benefits
For an analysis of the sensitivity of obligations in respect of pensions and other employee benefits as of December 31, 2024, and of the assumptions used as of that date, see Note D.19.1. to the consolidated financial statements for the year ended December 31, 2024.
The principal assumptions used (in particular, discount and inflation rates) and the market value of plan assets for the eurozone, the United States and the United Kingdom were reviewed as of June 30, 2025 to take into account changes during the first half of the year.
During the first half of 2025, Sanofi completed a further buy-in (amounting to €101 million) to cover the remaining uninsured liabilities arising under the main defined benefit pension scheme in the United Kingdom. Consequently, all scheme members are now fully insured as a result of buy-in transactions, except for liabilities rising from guaranteed minimum pension equalization (as described in Note D.19.1. to the consolidated financial statements for the year ended December 31, 2024).
Actuarial gains and losses arising on pensions and other post-employment benefits and recognized in equity are as follows (amounts reported before tax):

B.13. Off balance sheet commitments
Off balance sheet commitments to third parties as of December 31, 2024 are presented in Note D.21.1. to the consolidated financial statements for the year ended December 31, 2024.
The principal commitments entered into, amended or discontinued during the period are described below:
•In April 2025, Sanofi entered into a license and collaboration agreement with Earendil Labs for two bispecific antibodies in the field of autoimmune and inflammatory bowel diseases: HXN-1002 (targeting α4β7 and TL1A for potential treatment of moderate to severe ulcerative colitis and Crohn's disease) and HXN-1003 (targeting TL1A and IL23 for potential treatment of colitis and skin inflammation). Under the terms of the agreement, Earendil Labs received an upfront payment of $125 million, is eligible to receive up to a total of $1.7 billion in development and commercial milestone payments, and is eligible to receive tiered royalties on product sales.
As of June 30, 2025, Sanofi has not entered into any material new long-term renewable energy contract agreements as part of its sustainability strategy. The main existing agreements are presented in Note D.21.1. to the consolidated financial statements in the 2024 Form 20-F.
B.14. Litigation and arbitration proceedings
Sanofi and its affiliates are involved in litigation, arbitration and other legal proceedings. These proceedings typically are related to product liability claims, intellectual property rights (particularly claims against generic companies seeking to limit the patent protection of Sanofi products), competition law and trade practices, commercial claims, employment and wrongful discharge claims, tax assessment claims, waste disposal and pollution claims, and claims under warranties or indemnification arrangements relating to business divestitures.
The matters discussed below constitute the most significant developments since publication of the financial statements for the year ended December 31, 2024.
B.14.1. Products
Zantac product litigation in the US
As regards the ongoing Zantac product litigation in the US, the Separation Agreement (see Notes D.1 and D.22 to the consolidated financial statements in the 2024 Form 20-F) entered into between Sanofi and Opella specifies that Sanofi will indemnify the Opella group in respect of liabilities relating to (i) the commercialization of any Zantac branded products (i.e. products containing ranitidine as their active pharmaceutical ingredient) prior to closing, and (ii) all personal injury claims resulting from the manufacturing or handling of Zantac prior to closing.
In April 2025, Sanofi reached several settlement deals that in total resolve a majority of the Delaware State Court consolidated litigation. In addition, in May 2025, Sanofi reached settlements with the City of Baltimore and the New Mexico Attorney General, amicably resolving both those matters. Other cases are pending in various state courts.
On July 10, 2025, the Delaware Supreme Court unanimously reversed the Superior Court’s denial of Defendants’ Daubert motion based on the lack of reliability of plaintiff’s experts on causation and remanded its findings back to the Superior Court for proceedings consistent with the rulings in the opinion.
It is not possible, at this stage, to assess with certainty the outcome of these lawsuits.
Talc product litigation in the US
As of June 30, 2025, Sanofi was named as a defendant in approximately 900 ongoing product liability actions. To date, no cases have proceeded to trial.
It is not possible, at this stage, to assess with certainty the outcome of these lawsuits.
B.14.2. Patents
Praluent (alirocumab)-related Amgen patent litigation in Europe
Regarding Amgen’s EP 3 666 797, in April 2025, the Opposition Division of the European Patent Office ruled in Amgen’s favor and decided to maintain the patent as granted. Sanofi has appealed this decision to the Technical Board of Appeals of the European Patent Office, and the appeal hearing is scheduled for April 2026.
Plavix (clopidogrel) Litigation (Commonwealth) Litigation in Australia
This matter has been finalized with no possibility of appeal. The matter is closed.
B.14.3. Other litigation
Plavix (clopidogrel) - Attorney General action in Hawaii
In May 2025, the parties agreed to settle the Hawaii action, with Sanofi US to pay $350 million pursuant to its settlement agreement and Bristol-Myers Squibb to pay $350 million pursuant to its separate settlement agreement. The appeal and the underlying case were dismissed pursuant to the settlement. This matter is closed.

1. Condensed half-year consolidated financial statements
Plavix (clopidogrel)-related litigation in France
In the claim filed by the Caisse Nationale d’Assurance Maladie – CNAM (French Social Security), hearings were held in June 2025.
340B drug pricing program in the US
In the action filed by Sanofi against the Department of Health and Human Services (HHS), the Health Resources and Services Administration (HRSA) and their respective administrators, following a joint hearing held on April 29, 2025 in Sanofi’s case and the similar cases filed by Eli Lilly, Bristol Myers Squibb, Novartis, and Kalderos, the district court held on May 15, 2025 that, although Section 340B does not categorically prohibit the use of manufacturer rebates, it does not allow HRSA to require preapproval of a manufacturer rebate program.
The district court also held that HRSA’s letter determining that Sanofi would violate Section 340B if it launched its Credit (rebate) Model was arbitrary and capricious and remanded the Sanofi matter back to HRSA for further consideration. Eli Lilly, Bristol Myers Squibb, Novartis, and Kalderos appealed the district court’s decision to the Circuit Court. Those appeals, along with a similar appeal by Johnson & Johnson, have been expedited and consolidated.
ADR Proceedings in the US
In June 2025, Sanofi received notice that Hudson Headwaters Health Network (Hudson Headwaters) had filed a petition for monetary relief against Sanofi before the HRSA ADR (Administrative Dispute Resolution) Panel. Hudson Headwaters alleges that Sanofi has violated Section 340B by allowing only one contract pharmacy to be selected and utilized per covered entity, if the covered entity does not have an in-house pharmacy capable of dispensing its drug. Hudson Headwaters alleges that this Sanofi policy is an “overcharge” under Section 340B.
State Litigation in the US
In lawsuits filed by PhRMA and certain other manufacturers challenging a contract pharmacy law passed by the State of Mississippi, the court denied for each of the plaintiffs their preliminary injunctions in their respective lawsuits. The plaintiffs appealed the denials of the preliminary injunction motions.
Various other challenges to similar state laws have been filed by PhRMA and/or certain manufacturers in a number of other states, including in Colorado, Kansas, Louisiana, Maryland, Minnesota, Missouri, Nebraska, North Dakota, Oklahoma, Tennessee, Utah, South Dakota, and Vermont.
B.15. Other operating income and expenses
Other operating income amounted to €533 million in the first half of 2025 (versus €563 million in the first half of 2024), and Other operating expenses to €2,476 million (versus € 1,977 million in the first half of 2024).
Figures for the 2024 comparative period have been re-presented on a consistent basis to reflect the classification of Opella as a discontinued operation.
The main items included in Other operating income were: in the first half of 2025, (i) income from pharmaceutical partners of €87 million (versus €121 million in the first half of 2024), of which €70 million came from Regeneron (versus €96 million in the first half of 2024, see table below) and (ii) gains on disposals of assets and operations of €344 million, primarily on divestments of non strategic products (versus €319 million in the first half of 2024).
Other operating expenses for the first half of 2025 included €2,331 million of expenses related to Regeneron (compared with €1,841 million in the first half of 2024), as shown in the table below.
(€ million) June 30, 2025 (6 months) June 30, 2024 (6 months)

Restructuring and similar costs decreased by €630 million between June 30, 2024 and June 30, 2025. In the first half of 2024, restructuring and similar costs mainly comprised the impacts of (i) the renewal of the Job Management and Career Paths (GEPP) program in France to cover the 2024-2026 period, including scope extensions in the job profiles affected by transformations and (ii) a voluntary redundancy program announced in 2024 in connection with the reorganization of R&D operations to make Sanofi a leader in immunology.
B.17. Other gains and losses, and litigation
For the first half of 2025, Other gains and losses, and litigation is a charge of €57 million, mainly related to major litigation. That compares with a charge of €450 million in the first half of 2024, mainly comprising a provision recognized in respect of the litigation related to Plavix (clopidogrel) in the US state of Hawaii.

B.19. Income tax expense
Sanofi has elected for tax consolidations in a number of countries, principally France, Germany, the United Kingdom and the United States.
The table below shows the allocation of income tax expense between current and deferred taxes:
(€ million) June 30, 2025 (6 months)
June 30, 2024
   (6 months) (a)
Current taxes (1,202) (1,108)
Deferred taxes 491  729 
Total (711) (379)
Income before tax and investments accounted for using the equity method 3,582  2,462 
(a) Figures for the 2024 comparative period have been re-presented on a consistent basis to reflect the classification of Opella as a discontinued operation.

The difference between the effective tax rate (on income before tax and investments accounted for using the equity method) and the standard corporate income tax rate applicable in France is explained as follows:
(as a percentage)
June 30, 2025 (6 months)(b)
June 30, 2024 (6 months)(a)(b)
Standard tax rate applicable in France 25.8  25.8

(1.0) 2.8 
Effective tax rate 19.8  15.4 
(a)Figures for the 2024 comparative period have been re-presented on a consistent basis to reflect the classification of Opella as a discontinued operation.
(b)Rate calculated on the basis of the estimated effective tax rate for the full financial year (see Note A.2.).
(c)The difference between the French tax rate and tax rates applicable to foreign subsidiaries reflects the fact that Sanofi has operations in many countries, most of which have lower tax rates than France.
The 2024 component of the temporary exceptional corporate income tax contribution, introduced under the 2025 French Finance Bill, is included in the
tax charge but excluded from the calculation of the annual average effective tax rate in accordance with IAS 34.
(d)For the six months ended June 30, 2025, this line includes a tax expense of €17 million, representing the estimated impact of Pillar Two based on Sanofi’s current understanding of Pillar Two rules, and €52 million for the six months ended June 30, 2024.

B.21. Segment information
The segment information presented by Sanofi consists of a single operating segment: Biopharma.
The Biopharma operating segment comprises commercial operations and research, development and production activities relating to the Specialty Care, General Medicines and Vaccines franchises plus support and corporate functions, for all geographical territories. It also includes revenues generated from the manufacture of Consumer Healthcare products invoiced to Opella, which constitutes a related party with effect from the deconsolidation date (April 30, 2025). Those revenues, which before that date represented intragroup transactions classified within continuing operations, are presented within Other Revenues in the income statement. The Biopharma operating segment also includes the purchase price of Biopharma products manufactured by Opella.
The “Other” category comprises primarily, but not exclusively, Consumer Healthcare activities not transferred on the effective date of loss of control of Opella. These are primarily (i) hospital sales of Opella products in China, the transfer of which will be finalized no earlier than 2028; (ii) sales made by the dedicated entity Opella Russie, of which Sanofi continues to hold the capital (Sanofi is continuing to distribute Opella products in Russian territory under a distribution agreement signed in connection with the separation, the parties reserving the right to discuss the transfer of that entity during the term of the distribution agreement); and (iii) sales of the Gold Bond product range, which are continuing in the United States through the retained subsidiary Gold Bond LLC (holder of the associated worldwide property rights).
B.21.1. Segment results
Sanofi reports segment results on the basis of “Business operating income”. This indicator is used internally by Sanofi’s chief operating decision maker to measure the performance of the operating segment and to allocate resources.
“Business operating income” is derived from Operating income, adjusted as follows:
•amortization and impairment losses charged against intangible assets (other than software and other rights of an industrial or operational nature), are eliminated;
•fair value remeasurements of contingent consideration relating to business combinations (IFRS 3) or business divestments, and presented within the line item Fair value remeasurement of contingent consideration, are eliminated;
•expenses arising from the remeasurement of inventories following business combinations (IFRS 3) or acquisitions of groups of assets that do not constitute a business within the meaning of paragraph 2b of IFRS 3, are eliminated;
•amounts reported within the line items Restructuring costs and similar items are eliminated;
•other gains and losses (including gains and losses on major divestments), presented within the line item Other gains and losses, and litigation, are eliminated;
•other costs and provisions related to litigation, presented within the line item Other gains and losses, and litigation, are eliminated;
•the share of profits/losses from investments accounted for using the equity method is added, to the extent that this relates to joint ventures and associates with which Sanofi has a strategic alliance; and
•the portion attributable to non-controlling interests related to continuing operations and excluding the effects of the above reconciliation items, is deducted.

A/ Significant events of the first half of 2025
A.1. First-half overview
During the first half of 2025, Sanofi continued to implement its growth and innovation strategy, focused on launching major innovations, reallocating resources and developing cutting-edge R&D. Significant events connected with the implementation of this strategy are described below (for additional information on developments related to Research and Development see also section "A.2. Research and Development").
During the meeting of the Board of Directors on January 29, 2025, the Board authorized Sanofi to repurchase the Company's shares, for an amount not exceeding €5 billion, under the terms and conditions set by the General Meeting of April 30, 2024 in its 19th resolution. As part of this authorization, Sanofi entered into a share buyback agreement with its historical shareholder L'Oréal on February 2, 2025 for the acquisition of 2.34% of Sanofi’s share capital, equivalent to 29,556,650 shares, for a total amount of approximately €3 billion, representing a price of €101.50 per share. The conclusion of that agreement was approved by the Board of Directors on the same day prior to the signing of the agreement, and in accordance with the procedure set forth in Articles L. 225-38 et seq. of the French Commercial Code. In addition, on February 6, 2025 Sanofi entered into a mandate with an investment services provider to repurchase its own shares for a maximum amount of €2 billion, between February 7, 2025 and December 31, 2025.
As part of the Euro Medium Term Note program, Sanofi carried out two bond issues in the first half of 2025. On March 5, a first issue of €1.5 billion was completed, comprising €850 million of floating-rate bonds (3-month Euribor + 0.300%) maturing in March 2027, and €650 million of fixed-rate bonds (2.750% per annum) maturing in March 2031. On June 17, a second issue of €1.5 billion was completed, consisting of two tranches of €750 million each: one at a fixed rate of 2.625% per annum) maturing in June 2029, and the other at a fixed rate of 3.000% per annum maturing in June 2032. Sanofi will use the net proceeds from the issuance of these bonds for general corporate purposes.
On April 30, 2025, Sanofi announced the completion of the transaction with Clayton, Dubilier & Rice (CD&R) relating to Sanofi’s consumer healthcare business, Opella. Sanofi retains a 48.2% equity interest in OPAL JV Co, which indirectly holds 100% of Opella.. Bpifrance holds a minority stake of 1.8% and will be represented on Opella’s Board. As a result of the transaction, Sanofi has recognized a net gain of €2.7 billion, reported within the line item Net income from discontinued operations in the consolidated income statement. Sanofi has received total net cash proceeds of €10.7 billion, presented within the line item Net cash inflow from the Opella transaction in the statement of cash flows.
On May 22, 2025, Sanofi announced that it had entered into an agreement to acquire Vigil Neuroscience, Inc. (“Vigil”), a US-based publicly traded clinical-stage biotechnology company focused on developing novel therapies for neurodegenerative diseases. This acquisition in neurology enhances Sanofi’s early-stage pipeline and includes VG-3927, an oral small molecule TREM2 agonist currently in development for Alzheimer’s disease. Sanofi had previously invested $40 million in June 2024, including a pre-emptive right to VG-3927. Sanofi will acquire all outstanding common shares of Vigil for $8 per share in cash at closing. Based on $8.00 per share, the total equity value of Vigil represents approximately $470 million (on a fully diluted basis). Closing of the transaction is expected in the third quarter of 2025 subject to conditions customary for such a transaction, including the approval of holders of a majority of the outstanding shares of Vigil common stock; the expiration or termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976; and other customary conditions.
On May 27, 2025, Sanofi announced the completion of the acquisition of DR-0201, a targeted bispecific antibody developed by Dren Bio, Inc., a privately held clinical-stage biopharmaceutical company. The definitive agreement was signed on March 19, 2025. DR-0201, now named SAR448501, engages myeloid cells for robust B-cell depletion, as demonstrated in preclinical and early clinical studies. Under the merger agreement, Sanofi acquired Dren-0201, a subsidiary of Dren Bio, for an upfront payment of $600 million, supplemented by potential milestone payments of up to $1.3 billion contingent upon attainment of development and commercialization milestones.
On June 2, 2025, Sanofi and Blueprint Medicines Corporation (Blueprint), a US-based, publicly traded biopharmaceutical company specializing in systemic mastocytosis (SM), a rare immunological disease, and other KIT-driven diseases, entered into an agreement under which Sanofi agreed to acquire Blueprint.
The acquisition included a rare immunology disease medicine, Ayvakit/Ayvakyt (avapritinib), approved in the US and the EU, and a promising advanced and early-stage immunology pipeline. Blueprint’s established presence among allergists, dermatologists, and immunologists is expected to enhance Sanofi’s growing immunology pipeline.
Under the terms of the acquisition, Sanofi agreed to pay $129.00 per share in cash at closing, representing an equity value of approximately $9.1 billion for 100% of the shares. Blueprint shareholders also received one non-tradable contractual contingent value right (CVR) per share which entitles the holder to receive two potential milestone payments of $2.00 and $4.00 per CVR on the attainment of future development and regulatory milestones within the applicable milestone period, respectively, for BLU-808. The total equity value of the transaction, including potential CVR payments, represents approximately $9.5 billion on a fully diluted basis. In July 2025, Sanofi obtained control of Blueprint after all tender offer and merger conditions had been met.

Earnings per share was €4.74 for the first half of 2025, versus €1.80 for the first half of 2024. Business net income(2) was €4,152 million, up 7.6% on the first half of 2024, while business earnings per share (business EPS(2)) was €3.39, 9.7% up on the first half of 2024.
A.2. Research and development
During the first half of 2025, Sanofi maintained its R&D efforts with the aim of improving quality of life for people around the globe by developing innovative vaccines and medicines.
Progress made in R&D during the period is described in detail below, and an update on the R&D pipeline is presented in Section G/ of this half-year management report.
Immunology
Dupixent (dupilumab)
After evaluation under priority review by the US Food and Drug Administration (FDA), Dupixent was approved for the treatment of adult patients with bullous pemphigoid (BP), a chronic, debilitating, and relapsing skin disease with underlying type-2 inflammation that typically occurs in an elderly population. The approval is based on data from the pivotal ADEPT phase 2/3 study that evaluated the efficacy and safety of Dupixent compared to placebo in adults with moderate-to-severe BP. Additional regulatory applications are under review around the world, including in the European Union (EU), Japan, and China.
Dupixent was granted marketing and manufacturing authorization in Japan for the treatment of chronic obstructive pulmonary disease (COPD) in adults whose disease is not adequately controlled with existing therapy. The approval in Japan was based on data from the BOREAS phase 3 study.
itepekimab (IL33 mAb)
The AERIFY-1 phase 3 study evaluating itepekimab in former smokers with inadequately controlled chronic obstructive pulmonary disease (COPD) met the primary endpoint of a statistically significant reduction in moderate or severe acute exacerbations compared to placebo of 27% at week 52, a clinically meaningful benefit. With a reduction of only 2% at week 52, the AERIFY-2 phase 3 study did not meet the same primary endpoint. In the studies, patients were randomized to receive itepekimab every two weeks, every four weeks, or placebo, which was added to inhaled triple or double standard-of-care therapy. The safety of itepekimab was consistent across the studies, and adverse events were generally comparable between treatment and placebo groups. Sanofi and Regeneron are reviewing the data, including the apparent loss of benefit in AERIFY-2, and will discuss with regulatory authorities to evaluate next steps.
The CEREN 1 and CEREN 2 phase 3 studies of two dose regimens of itepekimab compared with placebo as add-on therapy to intranasal corticosteroids in patients with inadequately controlled CRSwNP commenced dosing the first patients.
amlitelimab (CD40 mAb)
The COAST 1 and SHORE phase 3 studies, part of the OCEANA study program in atopic dermatitis (AD), have completed patient recruitment ahead of schedule. Patient recruitment proceeded efficiently, providing an opportunity to optimize the overall sample sizes and robustness of the studies. The OCEANA program is anticipated to read out in 2025 (initial data) and 2026 (full data) and will provide the foundation for potential regulatory submissions.
Rezurock (belumosudil)
Based on a pre-specified interim analysis, a decision was made to discontinue the ROCKnrol-1 phase 3 study evaluating belumosudil in first-line chronic graft-versus-host disease. No major safety concerns were identified.
riliprubart (C1s mAb)
The US FDA granted orphan drug designation to riliprubart for the treatment of antibody-mediated rejection (AMR) in solid organ transplantation. This designation reflects Sanofi’s commitment to addressing a critical unmet need in transplant medicine, where AMR remains a significant challenge with no FDA-approved treatments available.
Rare diseases
Qfitlia (fitusiran)
The US FDA approved Qfitlia, the first antithrombin (AT)-lowering medicine for routine prophylaxis to prevent or reduce the frequency of bleeding episodes in adult and pediatric patients (aged 12 or older) with hemophilia A or B with or without factor VIII or IX inhibitors. The approval is based on data from the ATLAS phase 3 studies that demonstrated clinically meaningful bleed protection as measured by annualized bleeding rates across hemophilia patients with or without inhibitors. In conjunction with

the Qfitlia approval, the FDA also cleared Siemens Healthineers’ INNOVANCE® AT assay as a companion diagnostic for Qfitlia to measure AT levels. The medicine is also under regulatory review in China.
Cerezyme (imiglucerase)
The US FDA accepted for review the submission of a supplemental biologics license application (sBLA) for Cerezyme to treat patients with Gaucher disease type 3 (GD3), with no age limitation, for patients with GD1 and GD3. The FDA decision is expected in the first quarter of 2026.
rilzabrutinib (BTK inhibitor)
The US FDA granted orphan drug designation to rilzabrutinib, a novel, advanced, oral, reversible Bruton's tyrosine kinase (BTK) inhibitor that works via multi-immune modulation to target a reduction in vaso-occlusive crises (which may occur via inflammation), in sickle cell disease.
Neurology
tolebrutinib (BTK inhibitor)
The US FDA is evaluating under priority review the regulatory submission of tolebrutinib, the submission of which was accepted in the first half 2025, to treat non-relapsing secondary progressive multiple sclerosis (nrSPMS) and to slow disability accumulation independent of relapse activity. The FDA decision is expected before the end of 2025. A regulatory submission has also been accepted and is under review in the EU. The positive results from the HERCULES phase 3 study that form the basis for these regulatory submissions were published in the New England Journal of Medicine (NEJM) in April 2025. As part of the ongoing regulatory review, discussions with the FDA and the EMA are continuing with respect to efficacy and safety, including liver safety, from the clinical studies.
riliprubart (C1s mAb)
In Japan, riliprubart was granted orphan drug designation for people with chronic inflammatory demyelinating polyneuropathy (CIDP). Despite available therapies, many CIDP patients are left with residual symptoms, including weakness, numbness, and fatigue that can lead to long-term morbidity and diminished quality of life. Approximately 30% of people with CIDP do not respond to standard therapies. The orphan drug designation is granted to medicines that address rare medical diseases or conditions with unmet medical needs. There are currently approximately 4,000 people diagnosed with CIDP in Japan.
Oncology
Sarclisa (isatuximab)
Following the adoption of a positive opinion by the European Medicines Agency’s Committee for Medicinal Products for Human Use (CHMP), Sarclisa in combination with the standard-of-care regimen bortezomib, lenalidomide, and dexamethasone (VRd) was approved in January in the EU for the treatment of adult patients with newly diagnosed multiple myeloma ineligible for autologous stem cell transplant (NDMM, TI). Sarclisa in combination with VRd was also approved in Japan and China for the treatment of adult patients with NDMM, TI. These approvals are based on data from the IMROZ phase 3 study.
In January, Sarclisa in combination with pomalidomide and dexamethasone was approved in China for the treatment of adult patients with MM who have received at least one prior line of therapy, including lenalidomide and a proteasome inhibitor. This approval is based on results from the pivotal ICARIA-MM phase 3 study, using the China-based IsaFiRsT real-world study as bridging data.
Following the positive opinion by the CHMP, Sarclisa in combination with VRd was approved in the EU for the induction treatment of adult patients with NDMM who are eligible for autologous stem cell transplant. The positive CHMP opinion was based on part one results from the two-part, double-randomized, German-speaking Myeloma Multicenter Group (GMMG)-HD7 study.
Results from the IRAKLIA phase 3 study demonstrated that Sarclisa administered at a fixed dose subcutaneously (SC) via an on-body delivery system in combination with pomalidomide and dexamethasone (Pd) met its co-primary endpoints of non-inferior objective response rate and observed concentration before dosing at steady state compared to intravenous Sarclisa administered at a weight-based dose in combination with Pd in patients with relapsed or refractory (R/R) MM. These results will be the basis for regulatory submissions in the US and in the EU in 2025. Additional studies evaluating Sarclisa SC formulations across different combinations and lines of therapy are ongoing.
Vaccines
MenQuadfi (meningitis, six weeks+)
In May, the US FDA updated MenQuadfi’s approval, which now includes active immunization in children aged six weeks to 23 months for the prevention of invasive meningococcal disease caused by Neisseria meningitidis serogroups A, C, W, and Y.

Nuvaxovid (COVID-19)
Sanofi’s collaboration partner Novavax, Inc. announced that the US FDA had approved the biologics license application (BLA) for Nuvaxovid for active immunization to prevent coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in adults aged 65 years and older and individuals aged 12 through 64 years who have at least one underlying condition that puts them at high risk for severe outcomes from COVID-19 (e.g. asthma, cancer, diabetes, obesity, smoking). Nuvaxovid has been available for use in the US under Emergency Use Authorization since July 2022 and has full market approvals in the EU, UK and other countries. Under a May 2024 agreement, Sanofi has a co-exclusive license to co-commercialize Nuvaxovid in most countries worldwide and a sole license to Nuvaxovid for use in combination with Sanofi’s flu vaccines, currently in phase 1 clinical studies.
SP0087 (rabies)
The phase 3 study of the vero cell vaccine for the prevention of rabies read out positively on safety and immunogenicity. It is intended for use as a vaccine, and as a booster after two to three years. This study and previous studies support a US regulatory submission for prevention of rabies before and after exposure in all populations in the second half of 2025.
SP0282 (E. coli sepsis)
In February, a scheduled review of the E.mbrace phase 3 study conducted by an independent data monitoring committee (IDMC) determined that Sanofi’s and Johnson & Johnson’s vaccine candidate for extraintestinal pathogenic E. coli was not sufficiently effective at preventing invasive E. coli disease (IED) compared to placebo. No safety signals related to the vaccine candidate were identified and, throughout the study, investigators ensured that participants who developed IED received prompt treatment and care. As a result of the IDMC’s determination, the E.mbrace study was discontinued.
SP0218 (yellow fever)
A vaccine candidate is in development to prevent yellow fever infection in populations aged nine months and older. A phase 3 study in adults has commenced dosing the first patient.
A.3. Other significant events
A.3.1 Corporate governance
The Combined General Shareholders’ Meeting of Sanofi was held on April 30, 2025 at the Palais des Congrès in Paris, and was chaired by Frédéric Oudéa.

B/ Progress on implementation of the corporate social responsibility strategy
Introducing AIR: Sanofi's updated sustainability strategy
Building on a foundation in corporate social responsibility, Sanofi is introducing an updated sustainability strategy focused on the critical nexus between health and the environment. The AIR strategy addresses three key dimensions:
•Access to healthcare: expanding sustainable and equitable access to care programs for conditions impacted by environmental challenges, with initial focus on respiratory health and diabetes;
•Environmental impact: reducing the environmental impact of Sanofi’s medicines and vaccines and activities across the value chain while adapting to climate- and nature-related changes, with the ambition to reach Net Zero greenhouse gas emissions by 2045; and
•Resilience of healthcare systems: transforming the delivery of care through treatments and collective efforts that reduce the environmental footprint of healthcare systems.
This strategic focus recognizes that 70% of Sanofi’s medicine and vaccine portfolio, and more than 75% of Sanofi’s pipeline, target diseases that are impacted by climate and environmental challenges. It also puts Sanofi in a position to make a meaningful difference through access to care programs and actions to reduce the environmental footprint of healthcare. In these ways, Sanofi can help break the vicious circle between environmental degradation and declining human health.
Reducing the environmental footprint of healthcare: from ambition to results
With 3.6 billion people living in areas sensitive to climate change globally(1), Sanofi aims to reduce the environmental footprint of its medicines and vaccines via an eco-design approach, spanning the entire lifecycle - from raw materials, manufacturing, device and packaging, all the way to distribution, patient use, and end of life.
Starting in 2025, all new medicines and vaccines are adopting an eco-design approach, and by 2030, so will Sanofi’s 20 top sellers. Leveraging a science-based life cycle assessment methodology(2) and its own ISO-compliant eco-design digital intelligence tool, Sanofi has already achieved results in some of its top-selling medicines and vaccines:
•For Dupixent(3), the carbon footprint was reduced by 53%, water use cut by 62% and resource depletion reduced by 30%, by optimizing the active ingredient manufacturing process with the partner Regeneron.
•For Toujeo(3), 27% carbon footprint reduction, 11% water savings, and 18% resource reduction were achieved through improved manufacturing, packaging, and device production.
•For Hexaxim(3), production and packaging were also optimized, resulting in 17% lower carbon footprint, 19% less water use, and 6% fewer resources used.
All measures were compared to the previous generation of those medicines and vaccines. These improvements demonstrate our commitment to reducing environmental impact across ours product range.
Decarbonizing patient care pathways
The healthcare sector generates approximately 5% of global greenhouse gas emissions, with about half of that attributable to the patient care pathway(4). As a key player, Sanofi has the capacity to lead efforts to reduce emissions related to the patient journey.
Sanofi is intensifying its efforts to generate and analyze data that examine how its treatments can help decarbonize patient care pathways. Sanofi has already identified several ways to reduce environmental impact across patient care such as prioritizing prevention, optimizing treatments, and improving care settings.
In a recent study conducted in Spain using real-world evidence, Sanofi demonstrated the positive environmental impact of the all-infant 2023-2024 immunization program against RSV with Beyfortus(5). With immunization coverage exceeding 90% for in-season births and approaching 90% for out-of-season births(6), RSV prevention contributed to lower greenhouse gas emissions through reduced healthcare system utilization and decreased patient transportation, as evidenced by fewer visits to primary care physicians, emergency rooms, and specialists, as well as reduced hospitalizations. The program reduced RSV-related CO2 emissions by 47% compared to the previous year’s standard of care, equivalent to 4.9 kilotons of CO2.

C/ Events subsequent to June 30, 2025
The main events related to research and development that occurred between the end of the reporting period and the date on which the condensed consolidated financial statements were reviewed by the Board of Directors are described in section 'A.2. Research and Development'.
On July 22, 2025, Sanofi announced that it had entered into an agreement to acquire Vicebio Ltd (“Vicebio”), a privately held biotechnology company headquartered in London, UK. The acquisition brings to Sanofi an early-stage combination vaccine candidate for respiratory syncytial virus (RSV) and human metapneumovirus (hMPV), both respiratory viruses, and expands Sanofi’s capabilities in vaccine design and development with Vicebio’s ‘Molecular Clamp’ technology. Under the terms of the agreement, Sanofi would acquire all of Vicebio’s share capital for a total upfront payment of $1.15 billion, with potential milestone payments of up to $450 million based on development and regulatory achievements. The transaction is expected to close in the fourth quarter of 2025, subject to customary closing conditions, including receipt of regulatory approvals.

Exhibit 99.2
2. Half-year management report
D.1. Segment information
D.1.1. Operating segments
In accordance with IFRS 8 (Operating Segments), the segment information reported by Sanofi is prepared on the basis of internal management data provided to our Chief Executive Officer, who is the chief operating decision maker of Sanofi. The performance of the single operating segment is monitored individually using internal reports and common indicators. The operating segment disclosures required under IFRS 8 are provided in Note B.21. to our condensed half-year consolidated financial statements.
The segment information presented by Sanofi consists of a single operating segment: Biopharma.
The Biopharma operating segment comprises commercial operations and research, development and production activities relating to the Specialty Care, General Medicines and Vaccines franchises plus support and corporate functions, for all geographical territories. It also includes revenues generated from the manufacture of Consumer Healthcare products invoiced to Opella, which constitutes a related party with effect from the deconsolidation date (April 30, 2025). Those revenues, which before that date represented intragroup transactions classified within continuing operations, are presented within Other Revenues in the income statement. The Biopharma operating segment also includes the purchase price of Biopharma products manufactured by Opella.
The “Other” category comprises primarily, but not exclusively, Consumer Healthcare activities not transferred on the effective date of loss of control of Opella. These are primarily (i) hospital sales of Opella products in China, the transfer of which will be finalized no earlier than 2028; (ii) sales made by the dedicated entity Opella Russie, of which Sanofi continues to hold the capital (Sanofi is continuing to distribute Opella products in Russian territory under a distribution agreement signed in connection with the separation, the parties reserving the right to discuss the transfer of that entity during the term of the distribution agreement); and (iii) sales of the Gold Bond product range, which are continuing in the United States through the retained subsidiary Gold Bond LLC (holder of the associated worldwide property rights).
D.1.2. Business operating income
We report segment results on the basis of “Business operating income”. This indicator is used internally by Sanofi’s chief operating decision maker to measure the performance of the operating segment and to allocate resources. For a definition of “Business operating income”, and a reconciliation between that indicator and Income before tax and investments accounted for using the equity method, refer to Note B.21.1. to our condensed half-year consolidated financial statements.
In the first half of 2025, “Business operating income” amounted to €5,363 million (versus €4,938 million for the first half of 2024), while “Business operating income margin” was 27.0% (versus 26.9% for the first half of 2024). “Business operating income margin” is a non-IFRS financial measure that we define as the ratio of “Business net income” to our consolidated net sales.
Because our “Business operating income” and “Business operating income margin” are not standardized measures, they may not be directly comparable with the non-IFRS financial measures of other companies using the same or similar non-IFRS financial measures. Despite the use of non-IFRS measures by management in setting goals and measuring performance, these are non-IFRS measures that have no standardized meaning prescribed by IFRS.
D.2. Business net income (non-IFRS financial measure)
Net income attributable to equity holders of Sanofi for the first half of 2025 was to €5,812 million, 157.9% higher than the first half of 2024 (€2,246 million). “Business net income” for the first half of 2025 amounted to €4,152 million, 7.6% up on the first half of 2024 (€3,859 million). That represents 20.9% of net sales, versus 21.0% for the first half of 2024.
We also report “Business earnings per share” (business EPS), a non-IFRS financial measure which we define as business net income divided by the weighted average number of shares outstanding.
Business EPS was €3.39 for the first half of 2025, 9.7% up on the 2024 first-half figure of €3.09, based on an average number of shares outstanding of 1,225.5 million for the first half of 2025 and 1,249.4 million for the first half of 2024.

SANOFI     HALF-YEAR FINANCIAL REPORT 2025

Exhibit 99.2
2. Half-year management report
We define “Business net income” as Net income attributable to equity holders of Sanofi determined under IFRS, excluding the following items:
•net income from discontinued operations, including Opella;
•amortization and impairment losses charged against intangible assets (other than software and other rights of an industrial or operational nature);
•fair value remeasurements of contingent consideration relating to business combinations (IFRS 3), or to divestments of operations meeting the definition of a business;
•expenses arising from the remeasurement of inventories following business combinations (IFRS 3) or acquisitions of groups of assets that do not constitute a business within the meaning of paragraph 2b of IFRS 3;
•restructuring costs and similar items (presented within the line item Restructuring costs and similar items);
•other gains and losses (including gains and losses on major divestments), presented within the line item Other gains and losses, and litigation;
•other costs and provisions related to litigation (presented within the line item Other gains and losses, and litigation);
•(income)/expenses related to financial liabilities accounted for at amortized cost and subject to periodic remeasurement in accordance with paragraph B5.4.6 of IFRS 9 (Financial Instruments);
•tax effects related to the items listed above as well as effects of major tax disputes;
•the share of profits/losses from investments accounted for using the equity method, except for joint ventures and associates with which Sanofi has a strategic alliance; and
•the portion attributable to non-controlling interests of the items listed above.

(c)    The monitoring of impairment indicators for other intangible assets led to the recognition of impairment losses of€210 million in the first half of 2025 linked to research and development projects.
For the six months ended June 30, 2024, this line corresponds to a net reversal of impairment losses amounting to €371 million, mainly due to an increase in the expected recoverable amounts of certain marketed products and other rights in the Biopharma segment.
(d)    For the first half of 2025, Other gains and losses, and litigation is a charge of €57 million, mainly related to major litigation. That compares with a charge of €450 million in the first half of 2024, mainly comprising a provision recognized in respect of the litigation related to Plavix (clopidogrel) in the US state of Hawaii.
(e)    This line corresponds to the financial expense arising from remeasurement of the financial liability recognized in the balance sheet to reflect estimated future royalties on sales of Beyfortus in the United States.
(f)    In the first half of 2024, this line mainly comprised an impairment loss taken against the equity interest in EUROAPI, based on the quoted market price: €2.89 as of June 30, 2025, €2.55 as of June 30, 2024.
(g) Corresponds to the reconciliation between basic earnings per share (IFRS) and business earnings per share (non-IFRS): sum total of reconciling items divided by the weighted average number of shares outstanding.
SANOFI     HALF-YEAR FINANCIAL REPORT 2025

Exhibit 99.2
2. Half-year management report
The most significant reconciling items between “Business net income” and Net income attributable to equity holders of Sanofi relate to (i) the purchase accounting effects of our acquisitions of groups of assets and business combinations, particularly the amortization and impairment of intangible assets (other than software and other rights of an industrial or operational nature); (ii) the impacts of restructuring actions or transactions regarded as non-recurring, where the amounts involved are particularly significant; (iii) the remeasurements recognized through profit or loss in respect of (a) amounts receivable in respect of business divestments and accounted for at fair value, (b) liabilities arising from business combinations (IFRS 3) and accounted for at fair value, (c) liabilities accounted for at amortized cost and subject to periodic remeasurement under IFRS 9; and (iv) the net income from discontinued operations, including Opella. We believe that excluding those impacts enhances an investor’s understanding of our underlying economic performance, because it gives a better representation of our recurring operating performance.
We believe that eliminating charges related to the purchase accounting effects (particularly amortization and impairment of some intangible assets) enhances comparability of our ongoing operating performance relative to our peers. Those intangible assets (principally rights relating to research and development, technology platforms and commercialization of products) are accounted for in accordance with IAS 38 (Intangible Assets) and IFRS 3 (Business Combinations).
We also believe that eliminating the other effects of business combinations (such as the incremental cost of sales arising from the workdown of acquired inventories remeasured at fair value in business combinations) gives a better understanding of our recurring operating performance.
Eliminating restructuring costs and similar items enhances comparability with our peers because those costs are incurred in connection with reorganization and transformation Company’s programs, integration or separation as part of material deals.
We believe that eliminating the effects of transactions that we regard as non-recurring and that involve particularly significant amounts (such as major gains and losses on disposals, and costs and provisions associated with major litigation and other major non-recurring items) improves comparability from one period to the next.
Finally, remeasurements recognized in profit or loss during the period in respect of (i) assets or liabilities accounted for at fair value and recognized in the balance sheet in connection with business acquisitions or divestments or (ii) liabilities accounted for at amortized cost and subject to periodic remeasurement, generally determined on the basis of revised sales forecasts, are not reflective of our operating performance.
In addition to the items mentioned above relating to our continuing operations, “Business net income” excludes net income from the Opella discontinued operation, the results of which have been presented separately in the consolidated income statement since October 2024 (comparative figures have been re-presented on a consistent basis). Under IFRS 5 (Non-Current Assets Held for Sale and Discontinued Operations), a discontinued operation is defined as a component of an entity that has been disposed of or is classified as held for sale, and represents a separate major line of business. With effect from October 2024, “Business net income” from continuing operations is used by management to measure Sanofi’s financial performance on an ongoing basis. We believe that providing a performance measure aligned with our management approach is useful for investors and analysts.
We remind investors, however, that “Business net income” should not be considered in isolation from, or as a substitute for, Net income attributable to equity holders of Sanofi reported in accordance with IFRS. In addition, we strongly encourage investors and potential investors not to rely on any single financial measure but to review our financial statements, including the notes thereto, carefully and in their entirety.
We compensate for the material limitations described above by using “Business net income” only to supplement our IFRS financial reporting and by ensuring that our disclosures provide sufficient information for a full understanding of all adjustments included in “Business net income.”
Because our “Business net income” and “Business EPS” are not standardized measures, they may not be directly comparable with the non-IFRS financial measures of other companies using the same or similar non-IFRS financial measures.

D.3. Net sales
Net sales for the first half of 2025 amounted to €19,889 million, 8.3% higher than in the first half of 2024. Exchange rate fluctuations had a negative effect of 1.6 percentage points overall, due mainly to adverse trends in the euro exchange rate against the US dollar, Brazilian real and Mexican peso. At constant exchange rates (CER, see definition below), net sales rose by 9.9%, driven mainly by strong performances for Dupixent, ALTUVIIIO and Beyfortus. Divestments and medicines/portfolio streamlining had a negative impact of 0.4 percentage points on sales growth.

When we refer to changes in our net sales at constant exchange rates (CER), that means we have excluded the effect of exchange rates by recalculating net sales for the relevant period using the exchange rates that were used for the previous period, with the exception of countries treated as hyperinflationary economies under IAS 29 (i.e. Argentina and Turkey, see Note A.4 to our condensed half-year consolidated financial statements).

D.3.3. Biopharma segment
In the first half of 2025, revenue from the Biopharma business (see “Chapter D.1. Segment Information” for detailed segment information) was €19,889 million, up 8.3% on a reported basis and 9.9% at constant exchange rates (CER), driven by Dupixent and new launches.
Comments on the performances of our major Biopharma segment products are provided below.
New pharma launches
ALTUVIIIO (hemophilia A) generated sales of €542 million in the first half of 2025, primarily in the United States, driven by continued patient switches from older plasma-derived and recombinant factor medicines and to a lesser extent from non-factor treatments. Sales in the Rest of the World region, at €86 million, benefited from the launch in Japan and sales of supplies to Sanof'’s collaboration partner Sobi in Europe. Sales of the hemophilia A franchise (ALTUVIIIO + Eloctate) reached €683 million (+45% CER versus the first half of 2024), due to the strong commercial performance of ALTUVIIIO.
Nexviazyme/Nexviadyme (Pompe disease) sales reached €387 million, up 21.6% CER, driven by Europe (+38.9% CER) and the United States (+13.2% CER at €195 million) where all eligible/non-pediatric patients have converted from Myozyme/Lumizyme. Sales of the Pompe disease franchise (Nexviazyme/Nexviadyme and Myozyme/Lumizyme combined) reached €668 million, down 3.3% CER. Nexviazyme/Nexviadyme sales now represent 58% of the Pompe disease franchise.
Over the same period, sales of Sarclisa (multiple myeloma) reached €276 million, up 22.5% CER, driven by increased use in the front-line setting and market share gains globally.
Sales of Rezurock (chronic graft-versus-host disease, third line) reached €263 million in the first half, up 28.0% CER, driven by the United States (+18.1% CER) and by a significant increase in volumes in Europe (€23 million) and the Rest of the World (€20 million).
Sales of Cablivi (acquired thrombotic thrombocytopenic purpura) reached €136 million (+20.4% CER) in the first half, driven by an increase in the number of patients identified for this treatment (aided by artificial intelligence in the United States), and by launches in Europe and the Rest of the World.
Sales of Xenpozyme (acid sphingomyelinase deficiency) were €110 million in the first half, up 54.2% CER, reflecting an increase in the number of patients identified for this treatment across all regions.
Sales of Tzield (delayed onset of type 1 diabetes) reached €29 million (+38.1% CER) with sales benefiting from ongoing investment in education and progress in screening.
Qfitlia (hemophilia A and B) received marketing authorization in the United States on March 28, 2025, with sales in the first half of 2025 amounting to €1 million.
Immunology
Dupixent generated net sales of €7,312 million in the first half of 2025, up 19.1% on a reported basis and 20.7% at constant exchange rates. Global sales were driven by increased use in all approved indications, including atopic dermatitis, asthma, chronic rhinosinusitis with nasal polyposis, eosinophilic esophagitis, prurigo nodularis and chronic spontaneous urticaria, plus emerging use in COPD and bullous pemphigoid. In the United States, sales of Dupixent reached €5,283 million in the first half of 2025, driven by volume across all established and newly approved indications. In Europe, the product’s net sales for the first half of 2025 totaled €944 million, up 22.3% CER, reflecting strong momentum in all approved indications. In the Rest of the World region, Dupixent posted net sales of €1,085 million (+19.2% CER).
Other main medicines
Lantus sales were €876 million (+17.7% CER) in the first half of 2025. In the United States, sales were up 47.8% CER, benefiting from windfall sales due to the unavailability of competing medicines. In the Rest of the World region, sales were up 9.9% CER; conversely, sales in Europe decreased by 14.9% CER.
Toujeo sales rose by 10.3% CER to €692 million, driven by the Rest of the World region (+17.4% CER), where the product continued to increase its share of the buoyant basal insulin market.
Sales of the Fabry disease treatment Fabrazyme reached €525 million in the first half of 2025 (+1.0% CER), reflecting slight growth in the number of patients.
Plavix sales were up 1.9% CER at €473 million, reflecting volume growth in the Rest of the World region offset by volume-based procurement in China.
Lovenox sales decreased by 11.0% CER to €447 million, mainly as a result of the impact from biosimilar competition in Europe.
Cerezyme sales decreased by 8.6% CER to €363 million, due to the absence of inflationary pressure in 2025 and the cessation of treatment by some patients. Sales for the Gaucher disease franchise (Cerezyme and Cerdelga) were €539 million, down 5.8% CER.
In the first half of 2025, sales of Alprolix amounted to €305 million, up 13.7% CER, driven by the Rest of the Word region and the United States.
Sales of Myozyme/Lumizyme decreased by 24.8% CER in the first half of 2025 to €275 million, due to the ongoing shift to Nexviazyme/Nexviadyme as mentioned above.

First-half net sales of Praluent reached €267 million, an increase of 8.5% CER driven by higher sales in Europe, partly offset by lower sales in the Rest of the World region.
Thymoglobulin sales rose by 2.4% CER in the first half of 2025 to €248 million, driven by the Rest of the World region.
Cerdelga sales were €166 million, up 1.2% CER, reflecting continued growth in Europe but a decline in sales in the United States.
Eloctate posted sales of €135 million in the first half of 2025, down 28.8% CER, reflecting switches to ALTUVIIIO.
Sales of Aubagio were down 33.0% CER at €138 million, in line with the loss of exclusivity in the United States and Europe in 2023. Aubagio sales are expected to continue to decline.
Vaccines
In the first half of 2025, Vaccines sales were up 9.5% on a reported basis and 10.9% CER at €2,540 million, driven by expansion of Beyfortus into new markets.
Sales of Polio/Pertussis/Hib (PPH) Vaccines, including Boosters, rose by 2.4% CER to €1,361 million, primarily driven by demand for boosters to re-vaccinate adolescents and adults and by pediatric combos in the United States and international markets.
Meningitis, Travel and Endemics Vaccines sales increased by 5.5% CER to €609 million, reflecting a favorable ordering pattern in meningitis in the United States and the Rest of the World region, partly offset by phasing of travel and endemics vaccines.
Beyfortus sales reached €356 million, driven by additional sales in the Northern Hemisphere, in particular Germany. In the Rest of the World region, sales were driven by the roll-out in Japan and Brazil, and by expansion in Australia. Beyfortus is routinely protecting babies in more than 25 countries.
Sales of Influenza Vaccines reached €214 million, up 15.4% CER, due to one-offs from late-season immunizations in the US and Europe, while sales in the Rest of the World region decreased by 21.8% CER due to increased competition.
D.3.4. Net sales by geographical region

Figures for the 2024 comparative period have been re-presented on a consistent basis to reflect the classification of Opella as a discontinued operation, forming the basis for the percentage change data calculated in the above table.

In the first half of 2025, net sales in the United States reached €9,535 million, up 15.0% on a reported basis and 16.4% at constant exchange rates, driven strong growth for Dupixent, pharma launches and a temporary increase in demand for Lantus, although sales of some legacy medicines were lower. Vaccines sales were broadly stable, though Beyfortus sales decreased.
In Europe, 2025 first-half net sales rose by 1.8% both on a reported basis and at constant exchange rates, to €4,144 million. Growth was driven by Dupixent and launches, partially offset by lower sales of other main medicines and vaccines.
In the Rest of the World region, first-half net sales were up 3.6% on a reported basis and 6.4% at constant exchange rates at €6,210 million, driven mainly by Dupixent, Beyfortus, pharma launches, insulins, and PPH and booster vaccines, while other medicines and flu vaccines declined. Sales in China were down 1.3% on a reported basis but up 0.1% CER at €1,388 million, and were generally impacted by the declining market and by lower prices as a result of the renewed national reimbursement drug list and volume-based procurement.

D.4. Other income statement items
D.4.1. Other revenues
Other revenues decreased by 5.0% to €1,452 million in the first half of 2025 (versus €1,529 million in the first half of 2024).
The Other revenues line item includes VaxServe sales of non-Sanofi products, amounting to €842 million (versus €854 million in 2024). In addition, Other revenues includes sales of Opella products in markets retained by Sanofi (€206 million); sales to Opella (€61 million); royalties (€68 million); and sales of other services/manufacturing services (€275 million).
D.4.2. Gross profit
Gross profit for the first half of 2025 was €15,460 million, versus €13,923 million for the first half of 2024, a rise of 11.0%, driven by a portfolio shift towards specialty care and an enhanced product mix. Gross margin (the ratio of gross profit to net sales) also increased, reaching 77.7% in the first half of 2025 (versus 75.9% in the first half of 2024).
D.4.3. Research and development expenses
Research and development expenses (R&D expenses) in the first half of 2025 totaled €3,717 million (versus €3,335 million in the first half of 2024). The increase is explained mainly by (i) a one-time reimbursement in the first half of 2024 (the comparative period) for past ALTUVIIIO development, and (ii) wind-down costs for the discontinued E. coli sepsis vaccine candidate.
R&D expenses represent 18.7% of net sales, compared with 18.2% in the first half of 2024, and a year-on-year increase of 11.5%.
D.4.4. Selling and general expenses
Selling and general expenses amounted to €4,506 million in the first half of 2025 (22.7% of net sales), versus €4,303 million in the first half of 2024 (23.4% of net sales). The overall increase of 4.7% reflects continued support for launches and newer medicines in specialty care and vaccines.
The ratio of selling and general expenses to net sales was 0.8 of a percentage point lower than in the first half of 2024.
D.4.5. Other operating income and expenses
In the first half of 2025, Other operating income amounted to €533 million, slightly lower than in the first half of 2024, and Other operating expenses increased to €2,476 million (versus €1,977 million in the first half of 2024).
Overall, other operating income and expenses represented a net expense of €1,943 million in the first half of 2025, compared with a net expense of €1,414 million in the first half of 2024.

Other operating income and expenses (net) also includes gains on divestments of assets and operations totalling €344 million, mainly related to portfolio rationalization (versus €319 million for the first half of 2024).
D.4.6. Amortization of intangible assets
Amortization charged against intangible assets in the first half of 2025 amounted to €777 million, versus €898 million in the first half of 2024. This decrease was mainly driven by intangible assets reaching the end of their amortization periods.

D.4.7. Impairment of intangible assets
The monitoring of impairment indicators for other intangible assets led to the recognition of impairment losses of €210 million in the first half of 2025 linked to research and development projects.
In the first half of 2024, the results of impairment tests on other intangible assets led to a net reversal of impairment losses amounting to €371 million recognized in connection with the divestments of the ProXTen technology platform and of the marketed product Enjaymo, for which some related assets had been subject to impairment losses in previous years.
D.4.8. Fair value remeasurement of contingent consideration
Fair value remeasurements of contingent consideration assets and liabilities relating to business combinations (recognized in accordance with IFRS 3) represented a net expense of €61 million in the first half of 2025, versus a net expense of €66 million in the first half of 2024.
D.4.9. Restructuring costs and similar items
Restructuring costs and similar items amounted to a charge of €430 million in the first half of 2025, compared with a charge of €1,060 million in the first half of 2024.
Restructuring and similar costs decreased by €630 million between June 30, 2024 and June 30, 2025. In the first half of 2024, restructuring and similar costs mainly comprised the impacts of (i) the renewal of the Job Management and Career Paths (GEPP) program in France to cover the 2024-2026 period, including scope extensions in the job profiles affected by transformations and (ii) a voluntary redundancy program announced in 2024 in connection with the reorganization of R&D operations to make Sanofi a leader in immunology.
D.4.10. Other gains and losses, and litigation
For the first half of 2025, Other gains and losses, and litigation is a charge of €57 million, mainly related to major litigation. That compares with a charge of €450 million in the first half of 2024, mainly comprising a provision recognized in respect of the litigation related to Plavix (clopidogrel) in the US state of Hawaii.
D.4.11. Operating income
Operating income amounted to €3,759 million in the first half of 2025, versus €2,768 million in the first half of 2024. The year-on-year change was mainly due to the increase in Gross profit.
D.4.12. Financial income and expenses
Net financial expenses were €177 million in the first half of 2025, €129 million lower than the 2024 first-half figure of €306 million. The 2025 first-half figure includes a financial expense of €50 million (€176 million for the first half of 2024) in respect of the remeasurement of the liability recorded in the balance sheet for estimated future royalties on Beyfortus sales in the US.
Our cost of net debt (see the definition in Section D.7., “Consolidated balance sheet” below) was €57 million in the first half of 2025, compared with €67 million in the first half of 2024.
D.4.13. Income before tax and investments accounted for using the equity method
Income before tax and investments accounted for using the equity method for the first half of 2025 was €3,582 million, versus €2,462 million for the first half of 2024.
D.4.14. Income tax expense
Income tax expense totaled €711 million in the first half of 2025, versus €379 million in the first half of 2024, giving an effective tax rate (based on consolidated net income) of 19.8%, versus 15.4% in the first half of 2024. The increase in income tax expense was mainly due to a year-on-year decrease in restructuring costs relating to severance plans announced in the first half of 2025 and to Sanofi’s ongoing transformation projects (€113 million in the first half of 2025, versus €343 million in the first half of 2024). This was partly offset by a rise in the tax effects of amortization and impairment of intangible assets (€173 million in the first half of 2025, versus €48 million in the first half of 2024).
The effective tax rate on our “Business net income”(1) is a non-IFRS financial measure. It is calculated on the basis of business operating income, minus net financial expenses and before (i) the share of profit/loss from investments accounted for using the equity method and (ii) net income attributable to non-controlling interests. We believe the presentation of this measure, used by our management, is also useful for investors as it provides a mean of analyzing the effective tax cost of our current business activities. It should not be seen as a substitute for the effective tax rate based on consolidated net income.
When calculated on business net income, our effective tax rate was 21.0% in the first half of 2025, compared with 20.0% in the first half of 2024 and 19.8% for 2024 as a whole. The main factors in this year-on-year change were (i) the impact of the OECD Pillar Two model rules, which aim to ensure that large multinationals pay a minimum level of tax on the income arising in each jurisdiction where they operate; and (ii) the full effect of the 2024 portion of the temporary exceptional corporate income tax

D.4.16. Net income from continuing operations
Net income from continuing operations amounted to €2,956 million in the first half of 2025, compared with €2,061 million in the first half of 2024.
D.4.17. Net income from discontinued operations
Due to (i) the classification of Opella's assets and liabilities as held for sale since the announcement on October 21, 2024 of the opening of exclusive negotiations with CD&R for the transfer of those assets and liabilities and (ii) the assessment that Opella qualifies as a principal line of business within the meaning of IFRS 5, the net income or loss of Opella is presented in a separate line item, Net income from discontinued operations (see Notes B.1. and B.22. to our condensed half-year consolidated financial statements).
In the first half of 2025, Net income from discontinued operations amounted to €2,881 million, reflecting the net income of Opella until the date of loss of control and also including a net gain of €2,693 million resulting from the divestment of Opella as of the date of loss of control.
In the first half of 2024, Net income from discontinued operations amounted to € 202 million.
D.4.18. Net income
Net income amounted to €5,837 million in the first half of 2025, including a gain of €2,693 million on the divestment of Opella, versus €2,263 million in the first half of 2024.
D.4.19. Net income attributable to non-controlling interests
Net income attributable to non-controlling interests for the first half of 2025 was €25 million, against €17 million for the first half of 2024.
D.4.20. Net income attributable to equity holders of Sanofi
Net income attributable to equity holders of Sanofi amounted to €5,812 million in the first half of 2025, versus €2,246 million in the first half of 2024.
Basic earnings per share (EPS) was €4.74, compared with €1.80 for the first half of 2024, based on an average number of shares outstanding of 1,225.5 million for the first half of 2025 and 1,249.4 million for the first half of 2024. Diluted earnings per share was €4.72, versus €1.79 for the first half of 2024, based on an average number of shares after dilution of 1,230.7 million for the first half of 2025 and 1,253.8 million for the first half of 2024.
D.5. Segment results
In the first half of 2025, our “Business operating income” (see Note B.21.1. to our condensed half-year consolidated financial statements for a definition and further details) was €5,363 million, versus €4,938 million for the first half of 2024, an increase of 8.6%. Our “Business operating income margin” was 27.0% (versus 26.9% for the first half of 2024).

(b)For the six months ended June 30, 2025, this amount includes €(667) million in respect of cash and cash equivalents held by Opella as of April 30, 2025.

Net cash provided by/(used in) continuing operating activities represented a net cash inflow of €3,367 million in the first half of 2025, against €1,238 million in the first half of 2024.
Operating cash flow before changes in working capital for the first half of 2025 was €3,980 million, versus €3,608 million in the first half of 2024.
Working capital requirements decreased by €613 million in the first half of 2025, versus a decrease of €2,370 million in the first half of 2024; the year-on-year change mainly reflects a reduction in provisions for rebates in the United States as a consequence of the reduction in the list price of Lantus from January 1, 2024.
Net cash provided by/(used in) continuing investing activities represented a net cash outflow of €1,979 million in the first half of 2025, including the impact of the acquisition of Dren-0201, Inc. for $602 million (see Note B.1.2. to our condensed half-year consolidated financial statements). That compares with a net cash outflow of €3,355 million in the first half of 2024, resulting mainly from the acquisition of Inhibrx, Inc. for $2,035 million.
Acquisitions of property, plant and equipment and intangible assets totaled €1,420 million, versus €1,804 million in the first half of 2024. There were €845 million of acquisitions of property, plant and equipment (versus €882 million in the first half of 2024), corresponding primarily to investments in industrial facilities. Acquisitions of intangible assets (€575 million, versus €922 million in the first half of 2024) mainly comprised contractual payments for intangible rights, primarily under license and collaboration agreements.
After-tax proceeds from disposals (excluding disposals of consolidated entities and investments in joint ventures and associates) amounted to €434 million in the first half of 2025, compared with €516 million for the first half of 2024, and related mainly to divestments of assets and operations relating to portfolio streamlining and to disposals of equity and debt instruments.
Net cash provided by/(used in) continuing financing activities represented a net cash outflow of €4,441 million in the first half of 2025, compared with a net inflow of €92 million in the first half of 2024. The 2025 first-half figure includes (i) the dividend payout to our shareholders of €4,772 million (versus €4,704 million in the first half of 2024); (ii) €4,332 million of net external debt contracted (versus net external debt contracted of €5,102 million in the first half of 2024); (iii) movements in Sanofi’s share capital, including purchases of treasury shares and the related tax effects (€4,003 million, versus €302 million in the first half of 2024); and (iv) share capital increases of €29 million (compared with €21 million in the first half of 2024).
The net change in cash and cash equivalents in the first half of 2025 was an increase of €7,918 million, compared with a decrease of €1,915 million in the first half of 2024.
“Free cash flow” is a non-IFRS financial measure which is reviewed by our management, and which we believe provides useful information to measure the net cash generated from the Company’s operations that is available for strategic investments(1) (net of divestments(1)), for debt repayment, and for payments to shareholders. “Free cash flow” is determined from business net income(2) after adding back (in the case of expenses and losses) or deducting (in the case of income and gains) the following

Total assets were €124,959 million as of June 30, 2025, versus €132,798 million as of December 31, 2024, representing a decrease of €7,839 million.
Net debt was €5,102 million as of June 30, 2025, versus €8,772 million as of December 31, 2024. We believe the presentation of this non-IFRS financial measure, which is reviewed by our management, provides useful information to measure our overall liquidity and capital resources. We define “net debt” as (i) the sum total of short-term debt, long-term debt, and interest rate derivatives and currency derivatives used to manage debt, minus (ii) the sum total of cash and cash equivalents and interest rate derivatives and currency derivatives used to manage cash and cash equivalents.

(a)Net debt does not include lease liabilities, which amounted to €1,776 million as of June 30, 2025 and €1,906 million as of December 31, 2024.
To assess our financing risk, we use the “gearing ratio”, another non-IFRS financial measure. This ratio (which we define as the ratio of net debt to total equity) rose from 11.3% as of December 31, 2024 to 7.3% as of June 30, 2025. Analyses of our debt as of June 30, 2025 and December 31, 2024 are provided in Note B.9. to our condensed half-year consolidated financial statements.
Because our “net debt” and “gearing ratio” are not standardized measures, they may not be directly comparable with the non-IFRS financial measures of other companies using the same or similar non-IFRS financial measures. Despite the use of non-IFRS measures by management in setting goals and measuring performance, these measures have no standardized meaning prescribed by IFRS.
We expect that the future cash flows generated by our operating activities will be sufficient to repay our debt. The financing arrangements in place as of June 30, 2025 at the Sanofi parent company level are not subject to covenants regarding financial ratios and do not contain any clauses linking credit spreads or fees to Sanofi’s credit rating.

Other key movements in the balance sheet are described below.
Total equity was €70,279 million as of June 30, 2025, versus €77,857 million as of December 31, 2024. The net change reflects the following principal factors:
•an increase representing our net income for the first half of 2025 (€5,837 million);
•an decrease of €5,203 million due to currency translation differences arising on the financial statements of foreign subsidiaries, mainly due to movements in the US dollar;
•a decrease representing the dividend payout to our shareholders of €4,772 million; and
•the repurchase by Sanofi of 39,344,633 of its own shares during the first half of 2025 for a total amount of €3,988 million, plus €15 million of related tax payments.
As of June 30, 2025 we held 10.66 million of our own shares, recorded as a deduction from equity and representing 0.868% of our share capital.
Goodwill and Other intangible assets (€60,714 million in total) decreased by €5,299 million, due mainly to the impact of exchange rates and particularly to the fluctuation in the US dollar.
Investments accounted for using the equity method (€3,563 million) increased by €3,247 million. This increase primarily results from Sanofi retaining a 48.2% equity interest in OPAL JV Co following the loss of control of Opella, with CD&R holding 50% and Bpifrance holding 1.8%. For further details, please refer to Note B.1. to our condensed half-year consolidated financial statements.
Other non-current assets (€4,109 million) increased by €356 million.
Net deferred tax assets were €6,293 million as of June 30, 2025, compared with €6,166 million as of December 31, 2024, an increase of €127 million.
Non-current provisions and other non-current liabilities (€7,116 million) fell by €980 million relative to December 31, 2024. This reduction is mainly due to foreign exchange impacts (€522 million), and to the settlement reached on the litigation related to Plavix (clopidogrel) in the US state of Hawaii (see Note B.14. to our condensed half-year consolidated financial statements).
Liabilities related to business combinations and to non-controlling interests (€564 million) decreased by €77 million.

E/ Risk factors and related party transactions
E.1. Risk factors
The main risk factors to which Sanofi is exposed are described in the 2024 Form 20-F for the year ended December 31, 2024, filed with the US Securities and Exchange Commission on February 13, 2025(1).
The risk “Completion of the separation of Opella is subject to conditions that may not be satisfied and we may fail to realize any or all of the anticipated benefits of the separation and/or face unintended adverse impacts on our business” is replaced by the risk “We may fail to realize any or all of the anticipated benefits of the separation of Opella and/or face unintended adverse impacts on our business”, and should be read as follows:
“On April 30, 2025, we announced that the Opella transaction had been completed. Completion of the separation, for which we have incurred and are expected to incur significant costs, may not achieve the expected benefits in full or in part and there is no guarantee as to the timing of when or if any such benefits may be realized. The success of the transaction and its expected benefits will depend on several factors, including many factors outside of our control, and a number of assumptions that may prove incorrect.
Further to the separation, we may face a number of challenges relating to the implementation of the separation and to operating without the Opella business. There may be adverse financial, operational, regulatory, consumer, patient and reputational implications if we fail (either wholly or in part) to meet such challenges. Such adverse implications could impact our financial condition, results of operations and/or prospects. For example, since the separation our business is smaller and less diversified than previously, and is more susceptible to adverse developments in the remaining business and markets in which we operate. Accordingly, should any part of our remaining business underperform, this could have a greater adverse impact on our results or financial condition following separation than would have been the case prior to the separation. In addition, post-separation we have greater relative exposure to the global pharmaceuticals and vaccines markets and the associated risks and will no longer benefit from exposure to the Consumer Healthcare market we had prior to separation from the Opella business; this change makes us more reliant on R&D processes (see "—Several factors may hinder or delay Sanofi's research and development efforts to renew Sanofi's portfolio of medicines and vaccines" in Item 3.D. of the 2024 Form 20-F). There is a risk that the anticipated benefits of the separation may not be realized as expected.
The process of separating Opella from our remaining operations may be complex, time-consuming, and resource-intensive, and will require the separation of previously shared systems, processes, and infrastructure, which could result in unanticipated costs, delays, or ongoing operational inefficiencies. In connection with the divestiture, we are required to provide transitional services to Opella, which will require further resources and could expose us to additional liabilities.
Finally, as we retain a holding in Opella of 48.2% with veto rights only on certain matters, we will not control operational decisions and Opella's success will depend on its ability to retain talent and skilled professionals and take advantage of the opportunities that lie ahead in its segment. Therefore, our remaining holding in Opella may fall in value if Opella's strategy does not deliver the expected benefits.”
The risk “Our largest shareholder owns a significant percentage of the share capital and voting rights of Sanofi” is modified and should now be read as follows:
“Following the buy-back we made of a block of shares from L'Oréal in February 2025, and after cancellation on March 13, 2025 of said shares, as of June 30, 2025 L’Oréal held 7.23% of Sanofi's share capital and 13.12% of Sanofi's effective voting rights (excluding treasury shares). Individuals linked to L'Oréal currently serve on Sanofi's Board of Directors. For as long as L'Oréal retains its interest in our share capital and voting rights, it will remain in a position to exert influence in the appointment of directors and officers of Sanofi and in other corporate actions that require shareholder approval.”
Any of those risks, and others that we may not yet have identified, could materialize during the second half of 2025 or during subsequent periods, and could cause actual results to differ materially from those described elsewhere in this report.
E.2. Related party transactions
Our principal related parties are defined in Note D.33. to our consolidated financial statements included in the 2024 Form 20-F (page F-92)(1).
Note B.5. to our condensed half-year consolidated financial statements provides a description of the main transactions and balances for the six months ended June 30, 2025 with equity-accounted entities that qualify as related parties.
Sanofi did not enter into any transactions with key management personnel during the first half of 2025.
Financial relations with the Group’s principal shareholders fall within the ordinary course of business and were immaterial in the first half of 2025.

F/ Outlook
In 2025, net sales are anticipated to grow by a high single-digit percentage at CER(1) (previously mid-to-high single-digit). Sanofi confirms the expectation of a strong business earnings per share(2) (business EPS) rebound with growth at a low double-digit percentage at CER (before share buybacks), and now including all expenses from newly acquired businesses.
Sanofi intends to complete its €5 billion share buyback program in 2025 of which 80.3% has been completed to date.
Applying average July 2025 exchange rates, the currency impact on 2025 business EPS is expected to be around -6%.
Full-year business net income(1) for 2024 was €8,912 million, resulting in business earnings per share of €7.12.

This guidance was prepared on a basis comparable with that used to prepare our historical financial information, and in accordance with Sanofi accounting policies. It was also prepared on the basis of assumptions established by Sanofi and its subsidiaries, including but not limited to:
•trends in the competitive environment, in terms of innovative products and launches of generics;
•respect for our intellectual property rights;
•progress on our research and development programs;
•the impact of, and progress on, our operating cost containment policy;
•trends in exchange rates and interest rates;
•integration of the contribution from acquisitions; and
•the average number of shares outstanding.
Some of the above information, estimates and assumptions are derived from or rely on, in full or in part, judgments and decisions made by Sanofi management which may change or be amended in future.

Forward-looking statements
This document contains forward-looking statements as defined in the US Private Securities Litigation Reform Act of 1995, as amended. Forward-looking statements are statements that are not historical facts. These statements include projections and estimates and their underlying assumptions, statements regarding plans, objectives, intentions, and expectations with respect to future financial results, events, operations, services, product development and potential, and statements regarding future performance. Words such as “believe”, “anticipate”, “can”, “contemplate”, “could”, “plan”, “expect”, “intend”, “is designed to”, “may”, “might”, “plan”, “potential”, “objective” “target”, “estimate”, “project”, “predict”, “forecast”, “ambition”, “guideline”, “should”, “will”, “estimates”, “plans” or the negative of these and similar expressions are intended to identify forward-looking statements but are not the exclusive means of identifying such statements. Forward-looking statements are generally identified by the words “expects”, “anticipates”, “may”, “is considering”, “believes”, “intends”, “envisages”, “aims”, “plans”, “is designed to”, “could”, “forecasts”, “predicts”, “potential”, “objective”, “estimates”, “projects”, “is programming”, “is likely to” and “wants” or the negative thereof, and similar expressions. Although Sanofi’s management believes that the expectations reflected in such forward-looking statements are reasonable, investors are cautioned that forward-looking information and statements are subject to various risks and uncertainties, many of which are difficult to predict and generally beyond the control of Sanofi, that could cause actual results and developments to differ materially from those expressed in, or implied or projected by, the forward-looking information and statements.
These risks and uncertainties include among other things, the uncertainties inherent in research and development, future clinical data and analysis, including post marketing, decisions by regulatory authorities, such as the FDA or the EMA, regarding whether and when to approve any drug, device or biological application that may be filed for any such product candidates as well as their decisions regarding labelling and other matters that could affect the availability or commercial potential of such product candidates, the fact that product candidates if approved may not be commercially successful, the future approval and commercial success of therapeutic alternatives, Sanofi’s ability to benefit from external growth opportunities, to complete related transactions and/or obtain regulatory clearances, risks associated with intellectual property and any related pending or future litigation and the ultimate outcome of such litigation, trends in exchange rates and prevailing interest rates, volatile economic and market conditions, cost containment initiatives and subsequent changes thereto, and the impact that global crisis may have on us, our customers, suppliers, vendors, and other business partners, and the financial condition of any one of them, as well as on our employees and on the global economy as a whole. The risks and uncertainties also include the uncertainties discussed or identified in the public filings with the U.S. Securities and Exchange Commission (SEC) and the French Autorité des marchés financiers (AMF) made by Sanofi, including those listed under “Risk Factors” and “Cautionary Statement Regarding Forward-Looking Statements” in Sanofi’s Annual Report on Form 20-F for the year ended December 31, 2024. For an update on litigation, refer to Note B.14. “Legal and arbitration proceedings” to our condensed half-year consolidated financial statements for the six months ended June 30, 2025, and to section “A.3.2. Legal and arbitration proceedings”, and section “E/ Risk factors and related party transactions”, of this half-year management report.
With respect to any sustainability or environmental, social and governance (ESG)-related information contained herein, in light of the significant uncertainties inherent in such statements and other related information contained herein, investors should not regard these statements as a representation or warranty by Sanofi or any other person that Sanofi will achieve its goals, objectives, aspirations, metrics, plans or targets in any specified time frame or at all, including with respect to ESG and sustainability matters, and such statements and other information are dependent on future market factors, such as customer demand, continued technological progress, policy support and timely rule-making or continuation of government incentives and funding, and are forward-looking statements. Sanofi’s ability to achieve goals, objectives, aspirations, metrics, plans or targets in any specified time frame or at all, including with respect to ESG and sustainability matters, is subject to other conditions and considerations, both within and outside Sanofi’s control, that may affect its ability to meet such goals, objectives, aspirations, metrics, plans or targets, and/or put in place the initiatives required to meet them. Such conditions and considerations include but are not limited to the risk factors described above. In addition, historical, current, and forward-looking environmental and other ESG or sustainability-related statements may be based on standards for measuring progress that are still developing, internal controls and processes that continue to evolve, and assumptions that are subject to change in the future, including future laws and rulemaking. Sanofi plans to continue to evaluate its goals, objectives, aspirations, metrics, plans and targets and its approach to them and may make adjustments as it deems necessary in light of such considerations.
Other than as required by applicable law, Sanofi does not undertake any obligation to update or revise any forward-looking information or statements.

3. Statutory auditors’ review report on the half-yearly financial information
Period from January 1 to June 30, 2025
To the Shareholders,
In compliance with the assignment entrusted to us by your Annual General Meetings and in accordance with the requirements of article L. 451-1-2 III of the French Monetary and Financial Code (Code monétaire et financier), we hereby report to you on:
•the review of the accompanying (condensed) half-yearly consolidated financial statements of Sanofi, for the period from January 1, 2025 to June 30, 2025;
•the verification of the information presented in the half-yearly management report.
These condensed half-yearly consolidated financial statements are the responsibility of the Board of Directors. Our role is to express a conclusion on these financial statements based on our review.
1.   Conclusion on the financial statements
We conducted our review in accordance with professional standards applicable in France.
A review of interim financial information consists of making inquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures. A review is substantially less in scope than an audit conducted in accordance with professional standards applicable in France and consequently does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion.
Based on our review, nothing has come to our attention that causes us to believe that the accompanying condensed half-yearly consolidated financial statements are not prepared, in all material respects, in accordance with IAS 34 – standard of the IFRSs as adopted by the European Union applicable to interim financial information.
2.   Specific verification
We have also verified the information presented in the half-yearly management report on the condensed half-yearly consolidated financial statements subject to our review.
We have no matters to report as to its fair presentation and consistency with the condensed half-yearly consolidated financial statements.
