Acquisition of Chryso 1.6 After signing an agreement on May 20, 2021, Saint-Gobain completed its acquisition of Chryso on September 29, 2021 from funds advised by the global private equity firm Cinven. Chryso is a leading global player on the construction chemicals market, providing comprehensive additive solutions for sustainable construction, helping to significantly reduce the carbon footprint of concrete. The company employs 1,300 people and generates approximately €400 million in annual sales and around €85 million in Ebitda. The enterprise value of just over €1 billion represents a multiple of 12.0x Chryso’s last 12 months’ Ebitda of €85 million and a multiple of 7.6x post run-rate synergies of €50 million in year 5. 1.7 On December 6, 2021, Saint-Gobain and GCP Applied Technologies announced that they had entered into a definitive agreement pursuant to which Saint-Gobain will acquire all of the outstanding shares of GCP for USD 32.00 per share, in cash, in a transaction valued at approximately USD 2.3 billion (approximately €2.0 billion). This acquisition is a decisive step in establishing Saint-Gobain’s leading position worldwide in construction chemicals with total sales of more than €4 billion (up from €3 billion previously), and furthers the Group’s strategy as worldwide leader in light and sustainable construction. The agreed-upon price represents a multiple (before synergies) of approximately 13.2x GCP’s estimated 2022 adjusted Ebitda of USD 170 million, a multiple of 8.8x Ebitda post run-rate synergies of USD 85 million, and a premium of 39% above the volume-weighted average price per GCP share for the 30 unaffected trading days ended November 30, 2021. The transaction was unanimously approved by the Boards of Directors of both Saint-Gobain and GCP Applied Technologies. Saint-Gobain has obtained undertakings from Starboard and Standard Investments (formerly known as 40North/Standard Industries), to vote their respective stakes of 8.9% and 24.2% in favor of the transaction. Closing of the transaction is subject to GCP shareholders’ approval, antitrust approvals and satisfaction of other customary closing conditions; it is expected to close by year-end 2022.
