Sanofi launches 2026 global employee stock purchase plan

Paris, June 4, 2026. Sanofi’s global employee shareholder plan, Action 2026, opens on June 9, 2026, to around 75,000 employees in 52 countries. Now in its 12th year, the program demonstrates the ongoing commitment of Sanofi and its Board of Directors to involve employees in the company’s growth and results. In 2025 alone, more than 31,000 Sanofi employees - 44% of the total workforce, chose to invest in the company through the program. Today, nearly 90,000 current or former Sanofi employees are shareholders, and hold approximately 2.93% of its capital.

"The growing participation in our global employee share purchase plan speaks for itself: our employees believe in Sanofi's transformation and are proud to be part of it. This trust is our greatest asset to accelerate the execution of our strategy and maintain our success in the biopharmaceutical sector.” Belén Garijo, Chief Executive Officer

From June 9-29, 2026, employees will be offered shares at a subscription price of €59.87, which is equal to a 20% discount on the average of the 20 opening prices of Sanofi shares from May 6 to June 2, 2026. For every five shares subscribed, employees will be offered one free matching share (up to a maximum of four matching shares per employee). Every eligible employee may purchase up to 1,500 Sanofi shares within the legal limit (maximum payment amount may not exceed 25% of their gross annual salary, minus any voluntary contributions already made in employee savings schemes, such as the Company savings plan and/or the Group savings plan and/or the Group retirement savings plan (PERCO) — voluntary contributions to the separate PERCOL are not concerned by this limit) during 2026.

Detailed conditions

An eligibility condition of three months employment by the closing date of the offer period will apply. Eligible staff will be able to subscribe for shares from June 9, 2026 (inclusive) to June 29, 2026 (inclusive). The issue is expected to be completed and the delivery of the securities carried out by the end of July 2026. The number of shares offered is limited to 9,816,701 shares.

The new shares, including the matching shares (the "Shares"), will be subscribed (or delivered) either directly or through the intermediary of employee mutual funds ("FCPE"), depending on the regulations and/or tax regime applicable in the various countries of residence of those eligible for the capital increase. The Shares will be fully fungible with the existing ordinary shares comprising the share capital of Sanofi and will be entitled to dividends as from their issuance.

The voting rights attached to the subscribed Shares will be exercised directly by the employees.

Shares and the corresponding FCPE units subscribed, in France, within the framework of the Sanofi Group savings plan must be held for a period of approximately five years, i.e., until May 31, 2031, except upon the occurrence of an early release event provided for under Article R. 3324-22 of the French Labor Code. For shares subscribed outside of France within the framework of the Sanofi International group shareholding plan, this period could be shortened to three years, i.e., until May 31, 2029, depending on the legal and tax implications that may arise in the subscriber's country.

Admission of the Shares to trading on the Euronext Paris market (ISIN Code: FR0000120578) on the same line as the existing shares will be requested as soon as possible after the completion of the capital increase.
