Georgia Gulf Announces Results of Special Shareholder Meeting

Atlanta, Georgia, September 17, 2009 — Georgia Gulf Corporation (NYSE: GGC) announced the results of a special meeting of its shareholders held today. Shareholders approved an amendment to the Company’s charter increasing the number of authorized shares of common stock to 100 million.  As previously disclosed, this amendment has caused the 30.2 million shares of convertible preferred stock issued by the Company in its recently completed debt exchange to automatically convert to common shares on a one-for-one basis.  The Company now has approximately 33.0 million common shares outstanding, compared to approximately 2.7 million prior to today’s shareholder approval.

In addition, shareholders approved a new equity incentive plan for the issuance of equity awards for up to 3.033 million shares of the Company’s common shares to Company employees.

“The results of today’s special meeting of shareholders represent the final step in the successful completion of our debt exchange, which reduced Georgia Gulf’s debt by more than 50 percent and cut our annual interest expense by almost $70 million.  We are pleased that we were able to work with our investors to provide Georgia Gulf the financial flexibility to weather current economic conditions and to provide a solid foundation for growth. With our new capital structure, valuable asset base and skilled and dedicated employees, we are a strong business partner positioned for the long term in our chemicals and building products businesses,” commented Paul Carrico, Georgia Gulf’s President and CEO.
