Press release Regulated information

Brussels, Belgium – November 16, 2023 - 8:30 CET

Today, Syensqo SA/NV (“Syensqo” or the “Company”) announced that the Belgian Financial Services and Markets Authority has approved the prospectus relating to the admission to listing and trading of its shares on the regulated markets of Euronext in Brussels and Paris (the “Prospectus”), in connection with the previously announced planned separation of Solvay SA/NV (“Solvay”) into two independent listed companies – SOLVAY and SYENSQO – by way of a partial demerger of Solvay.

Subject to approval by Solvay’s shareholders at the extraordinary general meeting convened for December 8, 2023, Syensqo expects to become an independent listed company and its shares to commence trading on an ‘as-if-and-when-delivered’ basis on Euronext Brussels and Euronext Paris under ticker “SYENS” at market open at 9:00 a.m. CET on December 11, 2023.

The Prospectus comprises a registration document, dated June 29, 2023, together with a supplement to the registration document, a securities note and a summary of the prospectus, each dated November 15, 2023. Each constituent document of the Prospectus is available on the websites of Syensqo (www.syensqo.com/en/investors/spinoff/documents) and Solvay (www.solvay.com). The Prospectus will be notified to the French Financial Markets Authority (Autorité des marchés financiers) under the EU passporting regime.

Important legal information

The contemplated separation of Solvay and the Admission are subject to general market conditions and customary closing conditions, including the approval by Solvay’s shareholders at an extraordinary general meeting expected to be held on December 8, 2023 (or on a subsequent date to be announced by Solvay and the Company), of the contemplated partial demerger of Solvay (the “Partial Demerger”). The Company will keep the market informed, if and when appropriate, in accordance with applicable laws and regulations.

This press release is not a prospectus or other offering document for the purposes of Regulation (EU) 2017/1129 of June 14, 2017 (as amended, the “Prospectus Regulation”) or Regulation (EU) 2017/1129 as it forms part of UK domestic law by virtue of the European Union (Withdrawal) Act 2018, as amended (the “UK Prospectus Regulation”), and the allocation of shares of Syensqo to Solvay’s shareholders as part of the contemplated Partial Demerger is expected to be carried out in circumstances that do not constitute “an offer to the public” within the meaning of the Prospectus Regulation or the UK Prospectus Regulation.
