Georgia Gulf Reports Third Quarter 2011 Financial Results

ATLANTA— November 2, 2011 — Georgia Gulf Corporation (NYSE: GGC) today announced financial results for its third quarter ended September 30, 2011.

The company reported net sales of $929.6 million for the third quarter of 2011, 23 percent higher than the net sales of $758.0 million reported for the third quarter of 2010.  Georgia Gulf reported net income of $34.4 million, or $0.99 per diluted share, for the third quarter of 2011, compared to net income of $25.0 million, or $0.72 per diluted share, for the same quarter of the previous year.  Net income for the third quarter of 2011 was positively impacted by an $8.1 million release of tax reserves related to Royal Group prior to its acquisition by Georgia Gulf in 2006.

“Our operating income of $126.6 million in the first three quarters of 2011 was 57 percent higher than the same period in 2010,” said Paul Carrico, president and chief executive officer.  “Earlier this year we increased our adjusted EBITDA guidance based on an expectation that global macroeconomic conditions would improve.  However, North American building and construction markets remain sluggish, and the softness in the global economy has continued to pressure margins and export demand for our products into the fourth quarter of 2011.  Additionally, falling benzene and propylene prices caused inventory write-downs in our aromatics segment that further reduced earnings.

“With this backdrop, we are revising our guidance to $245-255 million of adjusted EBITDA in 2011, which is the bottom half of our original guidance in 2011.  This is an 18 to 22 percent improvement over our performance in 2010,” Carrico said. “In addition, our strong cash generation will allow us to reduce long term debt by approximately $82 million in 2011.

“Longer term, we are confident that our integrated chemicals and building products business is well positioned to take advantage of the eventual recovery in the economy and housing, as well as the continued competitive advantage that comes from our access to low-cost, domestic natural gas,” Carrico said.

Chlorovinyls

In the Chlorovinyls segment, third quarter 2011 net sales increased to $347.2 million from $316.7 million during the third quarter of 2010. The segment posted operating income of $46.3 million, compared to operating income of $46.1 million for the same quarter in the prior year.  The increase in net sales and operating income was primarily due to higher caustic soda and vinyl resin sales prices compared to the third quarter of 2010, mostly offset by lower sales volumes.

Building Products

In the Building Products segment, net sales were $262.5 million for the third quarter of 2011, increasing 18 percent (14 percent on a constant currency basis) compared to $222.9 million recorded for the same quarter in the prior year.  This sales increase was primarily driven by the benefit of the sales volumes resulting from the Exterior Portfolio acquisition in February 2011.  The segment’s operating income was $14.3 million for the third quarter of 2011, compared to $5.6 million of operating income during the same quarter of the prior year. The increase in operating income was primarily due to improved conversion costs, the addition of Exterior Portfolio and lower selling, general and administrative costs, offset in part, by higher raw material costs and a less favorable geographic and product sales mix.

Aromatics

In the Aromatics segment, net sales increased to $319.9 million for the third quarter of 2011 from $218.4 million during the third quarter of 2010. The increase was primarily due to higher sales prices and sales volumes.  During the third quarter of 2011, the segment recorded operating income of $1.7 million, compared to operating income of $12.1 million during the same quarter in 2010. The decrease in operating income was primarily due to a $9.3 million inventory write-down driven by a sharp decline in benzene and propylene prices in late September and early October.  This inventory write-down more than offset the benefit of higher sales prices, higher phenol and acetone sales volumes, and higher operating rates.

Liquidity and Debt Reduction

As of September 30, 2011, the company had $45.3 million of cash on hand as well as $247.9 million of borrowing capacity available under its asset-backed loan (ABL) facility.  As of the end of the third quarter of 2011, liquidity had increased by approximately $78 million compared to the end of the second quarter of 2011 primarily due to the seasonal decrease in working capital needs of the business and operating income.

On October 20, 2011 Georgia Gulf redeemed all $41.9 million of its outstanding 2016 10.75 percent senior subordinated notes.  This is in addition to the $22.2 million balance of its 2013 and 2014 senior notes that were redeemed in early April, 2011.  Georgia Gulf expects to repay an $18.2 million note by the end of the year, for a total long term debt reduction of $82.3 million in 2011.

Safe Harbor

This news release contains forward-looking statements subject to the “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995 and other federal securities laws.  These forward looking statements relate to, among other things, our sales and adjusted EBITDA guidance for 2011, and expectations of future results.   Forward-looking statements are based on management’s assumptions regarding, among other things, general economic and industry-specific business conditions, as well as the execution of our business strategy, and actual results may be materially different.  Risks and uncertainties inherent in these assumptions include, but are not limited to, uncertainties regarding future prices for our products,  industry capacity levels for our products, raw materials and energy costs and availability, feedstock availability and prices, changes in governmental and environmental regulations, the adoption of new laws or regulations that may make it more difficult or expensive to operate our businesses or manufacture our products, our ability to generate sufficient cash flows from our business, future economic conditions in the specific industries to which our products are sold, global economic conditions, the effectiveness of certain previously disclosed and recently implemented changes to our internal control over financial reporting, our ability to successfully integrate and execute our business plans for acquisitions and other factors discussed in the Securities and Exchange Commission filings of Georgia Gulf Corporation from time to time, including our Annual Report on Form 10-K for the year ended December 31, 2010 and subsequent quarterly reports on Form 10-Q.

Use of Non-GAAP Measures

Georgia Gulf supplements its financial statements prepared in accordance with Generally Accepted Accounting Principles (GAAP) with adjusted EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortization, as well as cash and non-cash restructuring charges and certain other charges, if any, related to financial restructuring and business improvement initiatives, gains on substantial modification of debt and sales of certain assets, certain purchase accounting and certain non-income tax reserve adjustments, and goodwill, intangibles, and other long-lived asset impairments) because investors commonly use adjusted EBITDA as a main component of valuation analysis of cyclical companies such as Georgia Gulf.  Adjusted EBITDA is not a measurement of financial performance under GAAP and should not be considered as an alternative to net income as a measure of performance or to cash provided by operating activities as a measure of liquidity. In addition, our calculation of adjusted EBITDA may be different from the calculation used by other companies and, therefore, comparability may be limited.

A reconciliation of 2011 adjusted EBITDA guidance to 2011 net income determined in accordance with GAAP is included in the table below.
