"The chlorovinyls business performed well following a period of lost production at the beginning of the fourth quarter of 2005 due to Hurricane Rita," said Ed Schmitt, Chairman, President and CEO, Georgia Gulf Corporation. "Limited production and low indus try inventories resulted in higher sales prices for vinyl resins, vinyl compounds and caustic soda. Our aromatics business experienced an operating loss for the fourth quarter due to weak demand in some end-use markets, increased Asian capacity and plant downtime.

"As for the first quarter of 2006, we expect the aromatics business to improve from the fourth quarter of 2005 but to continue to struggle overall. However, we are more optimistic that our chlorovinyls business will continue to perform well, as projections for high operating rates, good demand and declining natural gas prices should allow for continued improvement."

Fourth quarter 2005 net income of $18.7 million declined compared to third quarter 2005 net income of $27.9 million or $.82 per diluted share on sales of $525.2 million. The decline reflects overall higher raw materials and energy costs and lower sales volumes, which more than offset increased sales prices for vinyl resins, vinyl compounds and caustic soda.

For the year ended December 31, 2005, the Company had record sales of $2.3 billion, which is a 3 percent increase compared to 2004 sales of $2.2 billion. Net income of $95.5 million or $2.79 per diluted share declined compared to net income of $105.9 million or $3.17 per diluted share for 2004. This decline in net income was due to lower sales volumes for all products primarily as a result of the chloralkali plant turnaround in the second quarter of 2005 as well as Hurricanes Katrina and Rita in the third and fourth quarters of 2005. The negative impact of the chloralkali plant planned turnaround and an unplanned outage in the second quarter was about $.50 per diluted share and the negative impact associated with Hurricanes Katrina and Rita during the third and fourth quarters was approximately $.45 per diluted share. The effective tax rate for 2005 decreased to 32.9% from 36.5% in 2004 due to the favorable impact of changes in state tax apportionment rules and tax deductions created by the American Jobs Creation Act of 2004.

Chlorovinyls

Georgia Gulf's chlorovinyls business provided strong fourth quarter operating income of $54.5 million, an increase of 57 percent compared to fourth quarter of 2004 operating income of $34.7 million and an increase of 3 percent compared to the third quarter of 2005 operating income of $53.1 million. These improvements compared to both the fourth quarter of 2004 and third quarter of 2005 were due to increased sales prices for vinyl resins, vinyl compounds and caustic soda as supply remained tight and industry inventories were at historically low levels for a significant portion of the fourth quarter following outages caused by Hurricane Rita. These increased sales prices more than offset lower chlorovinyls sales volumes and higher raw materials and energy costs.

For the full year ended December 31, 2005, chlorovinyls operating income increased to $202.6 million from $165.9 million, an increase of 22 percent, compared to the full year 2004. This was a result of higher sales prices for all products outpacing higher raw materials and energy costs and lower sales volumes, as well as the adverse impacts of the Company's chloralkali planned turnaround and unplanned outage in the second quarter of 2005 and the hurricanes in the third and fourth quarters of 2005.

Aromatics

Georgia Gulf's aromatics business had an operating loss of $14.1 million for the fourth quarter of 2005 compared to operating income of 13.2 million for the fourth quarter of 2004 and declined compared to the operating loss of $1.9 million for the third quarter of 2005. The fourth quarter 2005 decrease compared to the fourth quarter of 2004 reflects significantly lower sales volumes and sales prices for all products as a result of hurricane-related lost production, decreased demand in certain end -use markets such as polycarbonates and increased Asian capacity.

Comparing the fourth quarter of 2005 to the third quarter of 2005, the decrease in operating income is a result of lower sales volumes for all products, which were not offset by slightly higher sales prices and lower benzene costs.

For the year ended December 31, 2005, the aromatics operating loss of $10.5 million represented a significant decrease compared to operating income of $50.6 million in the full year 2004. This decline is the result of significantly lower sales volumes for all aromatics products as a result of decreased demand, specifically in end -use markets such as polycarbonates, start-ups of additional Asian capacity, which resulted in reduced export opportunities, as well as fewer opportunistic cumene sales. In addition, the decline was also attributable to lost production in the third and fourth quarters of 2005 due to Hurricanes Katrina and Rita and raw materials costs increases. All of these factors more than offset higher sales prices for all aromatics products.
