Brussels, Belgium, June 17, 2015 ---In accordance with the applicable regulation (Article 11, §1 of the Belgian law of December 14, 2005, as modified by the law of December 21, 2013), Solvay must sell the outstanding Solvay bearer (non-dematerialized) shares on the market. Currently 33,099 shares (ISIN code: BE 0003470755) or 0.04% of the total issued equity, have not yet been converted into either dematerialized shares or registered shares.

Holders still have the possibility to convert their bearer shares until July 17, 2015, at the latest. This can be done by depositing them at any BNP Paribas Fortis agency in Belgium. All remaining bearer shares will be sold by Solvay on the Euronext Brussels stock exchange within a period of 3 months post the deadline of June 17, 2015. After deduction of incurred costs, the proceeds of this sale will be deposited at the Belgian Deposit and Consignment Office, where holders can still claim the reimbursement of their bearer shares, after deduction of the penalties as described in the law, as from January 1, 2016 until December 31, 2024.

The dematerialization process does not modify the capital of Solvay SA which is represented today by 84,701,133 shares.
