L’Oréal, Sanofi’s largest shareholder, has committed to a lock-up period of 1 year following the settlement of the Distribution, i.e., May 10, 2022

Paris, April 1, 2022. Sanofi announced today that the French Autorité des marchés financiers (AMF) has approved the listing prospectus prepared by EUROAPI in connection with the intended listing of its shares on the regulated market of Euronext Paris.

On March 17^th, 2022, Sanofi’s Board of Directors unanimously decided to submit for approval to its shareholders the proposed distribution in kind (the “Distribution”) of EUROAPI shares, via an additional extraordinary dividend, exclusively in kind, in addition to the previously proposed €3.33 cash dividend per Sanofi share. The Distribution relates to circa 58% of the share capital and voting rights of EUROAPI. In connection with the proposed Distribution, EPIC Bpifrance has agreed to purchase 12% of EUROAPI shares¹ from Sanofi, which confirmed its intention to hold circa 30% of the share capital and voting rights of the company after the Distribution.

The Distribution by Sanofi to its shareholders of EUROAPI shares in the form of an additional extraordinary dividend, exclusively in kind, is subject to the shareholders’ approval at Sanofi’s May 3, 2022 Ordinary and Extraordinary Shareholders’ Meeting.

Subject to certain customary exceptions, the following lock-up periods have been agreed:

• 2 years for Sanofi and EPIC Bpifrance following the settlement and delivery of the EUROAPI shares to be sold to EPIC Bpifrance; and

• 1 year for L’Oréal, Sanofi’s largest shareholder and for Karl Rotthier, CEO of the Company, following the settlement of the Distribution.

Main features of the Distribution are as follows:

• The Distribution ratio will be one (1) EUROAPI share per twenty three (23) Sanofi shares. No fractional EUROAPI shares will be issued. Any right to receive a fractional share will not be tradable or transferable. Consequently, when the amount of the Distribution to which a Sanofi shareholder is entitled does not correspond to a whole number of EUROAPI shares (i.e., less than twenty three (23) or a multiple of twenty three (23) Sanofi shares), the shareholder will receive the immediately lower number of EUROAPI shares, plus a cash payment for the whole of the balance arising from the price at which EUROAPI shares corresponding to fractional shares were sold. Each financial intermediary will sell the shares corresponding to the fractional shares of its entitled clients. As a result, the amount of the cash balance may vary depending on the shareholder’s financial intermediary;

¹ EPIC Bpifrance has agreed to purchase 12% in EUROAPI shares from Sanofi for up to €150 million, with the acquisition price to be determined based upon the thirty day volume weighted average trading price (“VWAP”) of EUROAPI’s shares on Euronext Paris, starting on the first day of trading.

• The technical reference price of EUROAPI shares is expected to be announced on May 5, 2022 by Euronext Paris after market close;

• The admission to trading of the EUROAPI shares and the ex-date (détachement) of the Distribution will occur at 9.00 am (CET) on May 6, 2022;

• The record date (the date on which positions are closed) for Sanofi shares to be eligible to the Distribution is scheduled on May 9, 2022;

• Payment of the Distribution (delivery and book-entry of the allocated EUROAPI shares) will take place on May 10, 2022.

Following the Distribution and the purchase of 12% of EUROAPI shares by EPIC Bpifrance, the Sanofi group will no longer control EUROAPI, resulting in a slightly accretive impact on Sanofi 2022 business operating income (BOI) margin².

Documents related to Sanofi shareholders’ meeting will be made available on April 11, 2022 on the Sanofi dedicated web page.

Investors are invited to read EUROAPI’s press release, issued concurrently and available on EUROAPI’s website announcing the AMF’s approval of its prospectus, and the listing prospectus in order to fully understand the potential risks and rewards associated with any decision to invest in EUROAPI shares. EUROAPI draws attention to the risk factors contained in Chapter 3 and Section 22.2 of the listing prospectus.
