Press release from the issuing company

Tuesday, January 29th, 2013

Georgia Gulf Corporation today announced that the pending merger with PPG’s commodity chemicals business has been completed, creating Axiall Corporation, effective immediately. The company will trade on the New York Stock Exchange under the ticker symbol AXLL beginning January 29.

“This merger of two industry-leading organizations creates an integrated chemicals and building products company well positioned to benefit from North America’s natural gas cost advantage as well as the recovery of the U.S. housing market,” said Paul Carrico, president and chief executive officer.

“I want to congratulate and thank the employees of both organizations,” Carrico said. “Some were directly involved in helping to complete this merger, and many others provided indirect support by ensuring that we operated our businesses safely and effectively throughout this process. In both cases, they played a vital role in the successful creation of Axiall.”
