Mark C. Rohr Assumes Chairman and CEO Roles at Celanese Corporation

Celanese Corporation (NYSE: CE), a global technology and specialty materials company and Fortune 500 company, announced today that Mark C. Rohr has assumed the roles of chairman and chief executive officer. Rohr was named by the Celanese Board of Directors in November 2011 to succeed David Weidman, who officially retired today.

“This is a tremendous time to be part of the Celanese team,” said Rohr. “I’m eager to work with these talented employees to create more value for customers and shareholders alike.”

Before assuming his new roles, Rohr visited Celanese sites and customers around the world including Asia, Europe and the Middle East. He will continue engaging with customers and other key stakeholders through aggressive outreach including a corporate blog, mobile applications and new website to be introduced later this year.

“Celanese is well-positioned to leverage our global capabilities against growth goals and translate our chemistry into solutions that add value,” said Rohr.

Rohr, a member of Celanese’s Board of Directors since 2007, previously held the positions of chief executive officer and chairman of Albermarle Corporation, as well as executive chairman of its Board. He will be based at Celanese’s corporate headquarters in Dallas, Texas.
