DALLAS (September 16, 2026) - Celanese Corporation (NYSE: CE), a global chemical and specialty materials company, today announced that Luis Fernandez-Moreno has been elected to the Company’s Board of Directors. A seasoned public and private company director, Mr. Fernandez-Moreno, 64, currently serves on the boards of Ingevity Corporation, a global specialty materials company, where he has been a director since 2016 and served as interim President and CEO from October 2024 to April 2025, and Select Water Solutions, a provider of sustainable water and chemical solutions to the energy industry. He brings over 40 years of experience and leadership in the performance materials, specialty ingredients and coatings industries across North America, Latin America and Europe.
