OKLAHOMA CITY, Oklahoma…March 8, 2010… LSB Industries, Inc. (NYSE: LXU) announced today results for the fourth quarter ended December 31, 2009. These results include $5.0 million of expenses related to the start-up of the chemical plant in Pryor, Oklahoma ("Pryor Facility").

Net sales were $115.3 million, a 35.8% decline from $179.5 million;

Operating income was $2.5 million compared to $1.8 million;

Net income was $38,000 compared to $3.6 million;

Net income applicable to common shareholders was $38,000 compared to $3.6 million;

Diluted earnings per common share were less than $0.01 compared $0.16.

Year 2009 Financial Highlights Compared to Year 2008:

Net sales were $531.8 million, a 29.0% decline from $749.0 million;

Operating income was $40.7 million compared to $59.2 million;

Net income was $21.6 million compared to $36.5 million;

Net income applicable to common shareholders decreased to $21.3 million from $36.2 million;

Diluted earnings per common share were $0.96 compared to $1.58.

Discussion of Fourth Quarter of 2009:

The $64.2 million decline in fourth quarter net sales includes a decrease of $21.4 million in our Climate Control Business and a decrease of approximately $41.1 million in our Chemical Business.

Consolidated operating income was $2.5 million compared to $1.8 million in 2008.

Operating income for the Climate Control Business was $5.6 million, a 30% decline from 2008 primarily primarily as a result of a 26.3% decline in net sales.

The Chemical Business reported an operating loss of $0.4 million in the fourth quarter of 2009, which included $5.0 million of start-up expenses for the Pryor Facility; in the fourth quarter of 2008, the Chemical Business incurred an operating loss of $3.1 million, which included Pryor Facility start-up expenses of $1.0 million. Excluding the Pryor Facility start-up expenses from both quarters, the Chemical Business’ operating income was $6.7 million higher compared to 2008 due to a number of factors including:

The timing of planned major maintenance ($3.7 million),

Reduced losses on natural gas and anhydrous ammonia hedge contracts ($3.2 million),

2008 firm sales commitments settled in the fourth quarter of 2009, resulting in higher gross profit compared to then current market prices ($1.4 million),

Other plant variances and efficiencies ($1.6 million),

Partially offset by lower gross profit on agricultural product sales ($3.2 million).

Although our consolidated operating income for the fourth quarter 2009 increased, net income decreased to $38,000 from $3.6 million for the same period of 2008. This decrease was primarily due to non-operating items in the 2008 fourth quarter, including a $5.5 million pre-tax gain from the repurchase of a portion of the Company’s subordinated debentures partially offset by a $3.1 million loss included in interest expense relating to interest rate contracts used as economic hedges. Additionally, income taxes for the 2008 fourth quarter included a benefit of $1.0 million compared to a $0.9 million provision for the 2009 fourth quarter.

Discussion of the Year 2009:

The sales decrease of approximately $217.2 million includes a decrease of $45.2 million in our Climate Control Business and a decrease of $166.3 million in our Chemical Business. Operating income for 2009 included approximately $17.2 million of start-up expenses associated with the Pryor Facility. Expenses associated with maintaining the Pryor Facility were $2.4 million in 2008.

Interest expense was $6.7 million for 2009 compared to $11.4 million for 2008, a decrease of approximately $4.7 million primarily due to $2.0 million of reduced losses associated with our interest rate contracts, a decrease of $1.6 million from the repurchase of the 2007 Debentures and a decrease of $1.1 million due declines in the LIBOR interest rates on our $50.0 million secured term loan.

Pre-tax income in 2009 includes a gain of $1.8 million from the extinguishment of debt as a result of acquiring $11.1 million of our 2007 Debentures at discounts to face value. The prior year includes a $5.5 million gain from acquiring $19.5 million of these debentures at discounts to face value.

Climate Control Business:

Net sales for the Climate Control Business for the fourth quarter 2009 totaled $59.7 million, a 26.3% decrease from the fourth quarter of 2008 due primarily to reduced construction activity. The segment’s operating income was $5.6 million for 2009 as compared to $7.9 million for 2008, with the decline primarily attributable to lower sales.

Despite a 26.3% decrease in sales, Climate Control’s gross profit was down only 16.7% or $4.1 million, as the gross margin improved to 33.9% for the fourth quarter of 2009 compared to 30.0% in the fourth quarter of 2008, despite lower factory overhead absorption stemming from a decline in unit sales volumes. The improvement in gross margin was primarily related to product mix, a $0.4 million gain on copper futures contracts as compared to a $0.6 million loss in 2008, as well as to efficiency improvements in our fan coil manufacturing operation and our engineering and construction services businesses.

Bookings of new product orders during the fourth quarter were $48.5 million compared to $59.1 million in the fourth quarter of 2008 and $49.1 million for the third quarter of 2009. Lower bookings were primarily due to lower levels of commercial construction activity caused by the recession. At December 31, 2009, the backlog of confirmed customer product orders was $32.2 million compared to $39.4 million at September 30, 2009 and $68.5 million at December 31, 2008.

Chemical Business:

Net sales for the Chemical Business for the fourth quarter 2009 were $53.7 million, or 43.3% below 2008. The decrease is primarily attributable to steep declines in commodity prices including the selling prices for our products accompanied by significantly lower raw material feedstock costs and lower tons sold in our mining markets.

The Pryor Facility project to begin production of anhydrous ammonia and UAN is still underway despite numerous delays. In January 2010, we began production of anhydrous ammonia, which is the initial feedstock for the production of UAN, but at production rates lower than our targeted rates. We are continuing to produce and store anhydrous ammonia while we are activating the Urea plant. The start-up of the Urea plant has encountered delays, due to extended lead times to refurbish certain major equipment items, resulting in significant increases in our previous estimates of the start-up costs. When we reach sustained targeted production rates of UAN, we will issue an announcement. For 2009, we incurred approximately $17.2 million of expenses primarily consisting of start-up costs. Currently, the Pryor Facility monthly operating start-up costs, prior to production of UAN at sustained targeted rates, are approximately $1.6 million in addition to variable costs such as natural gas and electricity.

CEO’s Remarks:

Jack Golsen, LSB’s Board Chairman and CEO stated: "Excluding the start-up costs of the Pryor Facility incurred during the fourth quarter, both our Chemical and Climate Control businesses operated profitably in a very challenging economy."

Mr. Golsen went on to say, "Due to current economic conditions, especially in the commercial construction sector, product orders and sales in our Climate Control Business have declined. Once the economy turns, we look forward to a resumption of growth in this business. We have seen some initial positive effects from the tax benefit provisions for geothermal heat pumps, which are part of the federal economic stimulus package, but these gains have been more than offset by the effects of the recession. We are continuously developing and introducing new green products, and we are investing in programs that we expect will stimulate the growth of our Climate Control Business."

He continued, "With respect to our Chemical Business, signs point to improvement in 2010 in all of its markets. We are especially pleased to see UAN pricing firming following a period of low prices. Looking ahead, the outlook is good for grain and crop production and fertilizer required to support them, including UAN. Despite the delays, we remain confident that the Pryor Facility will be a valuable asset for LSB once it is fully operational. We estimate that our all-in costs to refurbish the Pryor Facility are a fraction of the cost to construct a new plant with comparable capacities."

Discussing LSB’s financial condition, Mr. Golsen noted, "During the fourth quarter, we continued to strengthen our balance sheet, by reducing long-term debt, and increasing cash. During the fourth quarter, we purchased $1.0 million face value of our Debentures that are due in 2012 in a negotiated transaction at a discount from face value bringing our total purchases of our Debentures during 2009 to $11.1 million face value. As a result of these and prior acquisitions of these Debentures, only $29.4 million remained outstanding at December 31, 2009.

"While we look forward to an economic recovery, we have and will continue to invest in the areas that we believe have long-term strategic growth potential for LSB."
