Acquisition

Paris, April 7, 2015

Saint-Gobain extends the date of validity of its agreement with the Burkard family relating to the sale of the shares of Schenker-Winkler Holding

Saint-Gobain and the Burkard family have decided to amend their agreement relating to the sale of the shares of Schenker-Winkler Holding (SWH) that holds a controlling stake in Sika and to extend the date of validity of their agreement until 30 June 2016. At such date, Saint-Gobain will have an option to extend the agreement.

Saint-Gobain and the Burkard family have also adapted their agreement to take into account shares of Sika previously held directly by the Burkard family that have recently been sold by it to SWH, as well as additional shares purchased by SWH. As the family does not own any shares in Sika, there is no group formed by the Burkard family and Saint-Gobain as per the Swiss stock exchange rules.

Under no circumstance can Saint-Gobain be forced to purchase the shares of SWH if its stake in Sika would not represent the majority of the voting rights or if such acquisition would trigger the obligation to launch a mandatory offer to all Sika shareholders.
