Solvay today announced the future Board of Directors of SOLVAY, effective upon completion of the planned separation of Solvay into two companies – SOLVAY and SYENSQO – which is on track to be completed in December 2023.

Nicolas Boël, Chairman of Solvay’s Board of Directors, said, “Ensuring we have the right Board in place to guide SOLVAY’s strategy and oversee its ambitious goals was a top priority when we embarked on the separation project in 2022. We are building on the successful transformation led by Dr. Ilham Kadri as CEO of the Group – and I want to solemnly thank her for her accomplishments. The Directors we are announcing today collectively possess the experience, leadership, independence and diversity needed to help SOLVAY build on its solid foundations to enter into a new era of sustainable value creation. Guiding a 160-year-old business into a carbon-neutral world is an exciting task, and we are confident that we have the right board and right team to do so, enabling SOLVAY to deliver sustainable value for all generations to come.”

Pierre Gurdjian, Incoming Chair of the SOLVAY Board of Directors, said, “I am honored to take on the role of Board Chair at this historic new beginning for SOLVAY. I want to thank Nicolas Boël, who was instrumental in the Group’s successful journey during his twelve-year tenure as Chairman. Together with my fellow directors, we look forward to working closely with Philippe Kehren  and the leadership team to build an essential chemicals leader across attractive and resilient end markets. Megatrends such as renewable energy, resource efficiency, sustainable resources and demographics will give SOLVAY compelling opportunities to enhance value through expansion and consolidation. My fellow directors are accomplished leaders with reputations for overseeing organizations focused on operational excellence, and together we will leverage our deep understanding of SOLVAY’s people, customers and strategy to help guide the company into the future.”
