FOR IMMEDIATE RELEASE

LSB INDUSTRIES, INC. REPORTS RESULTS FOR THE

2012 THIRD QUARTER AND EXPECTS AN IMPROVED 2012 FOURTH QUARTER

OKLAHOMA CITY, Oklahoma…November 6, 2012… LSB Industries, Inc. (NYSE: LXU) announced today results for the third quarter ended September 30, 2012.

Third Quarter 2012 Financial Highlights Compared to Third Quarter 2011:

Discussion of Third Quarter of 2012:

The $5.6 million increase in consolidated sales includes a $7.4 million or 7.2% increase in Chemical Business sales and a $3.8 million or 5.3% decrease in Climate Control Business sales.

For the third quarter of 2012, Chemical Business sales volumes and operating income were adversely affected by certain ongoing issues at two of its facilities as summarized below.

During the third quarter of 2012, the Pryor, Oklahoma plant, (the “Pryor Facility”) experienced problems with the ammonia conversion process at its primary ammonia plant. As a result, third quarter total production was only 50% of the targeted production rate. We estimate that the Pryor Facility’s third quarter operating income was at least $14 million lower than it would have been had ammonia production been at or near targeted levels, based upon the selling price of ammonia and urea ammonium nitrate (“UAN”) during the quarter. We believe this condition will continue until the ammonia converter is replaced in early 2013. However, as of the date of this report, the Pryor Facility’s ammonia production has stabilized at approximately 80% of our targeted production rate.

As previously reported, the El Dorado, Arkansas plant (the “El Dorado Facility”) was damaged on May 15, 2012 when a reactor in its 98% concentration nitric acid plant (“DSN” plant) exploded. As a result, the production at the El Dorado Facility for the third quarter of 2012 was lower than otherwise would have been expected resulting in lost absorption and gross profit margins. In addition, in order to satisfy certain customer product requirements, nitric acid and sulfuric acid were purchased on the open market and resold at a negative gross profit margin. We estimate that the combined negative impact to operating profit resulting from lost sales, lost profits and extra expenses for the third quarter was at least $9 million. We expect this situation to continue, but to a lesser degree when the sulfuric acid plant is brought back into production during the fourth quarter. Our insurance policy provides business interruption coverage, which we believe will cover most of these lost profits and extra expenses. We believe that the first installment of business interruption proceeds will be received no earlier than the first quarter of 2013.

Our Climate Control Business operating income for the third quarter of 2012 was $6.9 million, or $1.9 million lower than the same period of 2011, primarily the result of lower sales of our residential products and to a lesser extent, reduced gross margins on commercial/institutional products due to product mix, discounting and operating inefficiencies related to the lower sales volumes.

First Nine Months 2012 Financial Highlights Compared to First Nine Months 2011:

The $8.0 million decrease in sales included a $14.3 million decrease for the Climate Control Business offset by a $2.7 million increase in Chemical Business and a $3.6 million increase in Other sales. The decrease in consolidated operating income was primarily the result of decreases in the Chemical Business operating income of $11.9 million and $6.4 million in the Climate Control Businesses.

Third Quarter Chemical Business Overview:

Sales for the Chemical Business were $110.2 million, an increase of $7.4 million compared to the same period in 2011, which included a $3.1 million increase in agricultural products sales, a $2.2 million increase in industrial acids and other product sales, and a $2.1 million increase in mining products sales. Agricultural sales dollars increased due primarily to the impact of product mix change from UAN to agricultural grade AN and ammonia. However, agricultural sales in both the third quarters of 2012 and 2011 were lower than otherwise would have been realized due to the unplanned downtime and reduced ammonia production at the Pryor Facility in both quarters, and lower volumes at our Cherokee, Alabama facility (the “Cherokee Facility”) due to an extended planned Turnaround during the 2012 quarter. The increase in industrial acids and other sales in dollars was primarily due to our ability to pass through higher raw material cost of ammonia to our contractual customers.

The Chemical Business operating income for the third quarter of 2012 was $7.5 million or approximately $0.4 million higher than the same period of 2011.

Third Quarter Climate Control Business Overview:

Our Climate Control sales for the third quarter of 2012 were $68.0 million, or $3.8 million below the same period in 2011, and includes a $5.0 million decrease in geothermal and water source heat pump sales and a $0.2 million decrease in hydronic fan coil sales, partially offset by a $1.4 million increase in other HVAC sales attributable to higher sales in our custom air handlers. From a market sector perspective, the net decrease includes a $3.3 million decrease in residential sales and a $0.5 million decrease in commercial/institutional product sales. Generally, we believe the overall decline can be attributed to lower consumer confidence in the economy resulting in lower discretionary spending on non-essential energy saving improvements, including geothermal technology products, which have a higher initial cost and longer payback time frame due to the current relatively low natural gas prices.

Our Climate Control operating income for the third quarter of 2012 was $6.9 million, or $1.9 million lower than the same period of 2011 primarily the result of lower sales of our residential products, and to a lesser extent reduced gross margins on commercial/institutional products due to product mix, discounting and operating inefficiencies related to lower sales volumes.

Bookings of new product orders were $65.6 million in the third quarter of 2012 compared to $66.8 million for the second quarter of 2012; and $65.7 million for the third quarter of 2011. At September 30, 2012, the backlog of confirmed customer product orders was $51.3 million compared to $50.2 million at June 30, 2012.

CEO’s Remarks:

Jack Golsen, LSB’s Board Chairman and CEO stated, “Continued problems with the ammonia converter at Pryor’s main ammonia plant have prevented us from reaching optimum production rates. However, as of the date of this report, the Pryor Facility’s ammonia production has stabilized at approximately 80% of our targeted production rate of 600 tons per day. Additionally, market prices for ammonia have increased. If these trends continue through year-end, the increase in production and pricing should offset most of Pryor’s lost margin experienced during the third quarter. Our plan at Pryor includes replacing the ammonia converter and making other modifications in early 2013 that should allow us to achieve our targeted rates.”

Mr. Golsen further remarked, “To replace the lost production capacity resulting from the loss of the DSN plant, our current plan is to construct a separate nitric acid plant and to install a separate nitric acid concentrator plant at the El Dorado Facility. We expect to complete these projects by mid-2015. The three regular nitric acid plants at the El Dorado Facility that were damaged on May 15, 2012 when the DSN plant exploded are back in production. Repairs should be completed on the El Dorado Facility’s sulfuric acid plant during the fourth quarter, at which time sulfuric acid production should restart. In addition, our Cherokee Facility was down for a planned Turnaround in the third quarter which resulted in 31 days of lost UAN production. The current plan is for the Cherokee Facility to be in full production during the fourth quarter.”

Mr. Golsen concluded, “We remain optimistic about the prospects for our agrochemical business, as most market indicators point to positive supply and demand fundamentals for the types of nitrogen fertilizer products we produce and sell. Whereas the current markets for our climate control products remain soft, our business is well positioned to take advantage of the economic recovery when it occurs. The 2012 third quarter was not an indicative reporting period, and we expect a much improved fourth quarter 2012 and a further improvement in 2013.”

Balance Sheet

Mr. Golsen noted, “At September 30, 2012, stockholders’ equity was $342 million and our long-term debt to equity ratio was 0.2 to 1.”

Natural Gas Hedge Working Interest

As previously announced, we recently acquired a working interest in certain Marcellus Shale natural gas properties located in Wyoming County, PA for $49 million. The purpose of this transaction is to provide us with a hedge against potential inflation in natural gas prices for a portion of our chemical plants’ feedstock requirements, specifically for the production of nitrogen products such as anhydrous ammonia and UAN. The reserves associated with this investment equate to approximately 20% of our natural gas requirements for the next eight years and carry a present value cost of an estimated $2.30 per mcf, including development and operating costs.

Notes to Unaudited Financial Highlights

Nine Months and Three Months Ended September 30, 2012 and 2011

For the first nine months of 2012, we believe the cumulative adverse impact to operating income due to the planned and unplanned downtime and reduced production at the Pryor Facility was an estimated $38 million (of which $14 million related to the third quarter of 2012) including lost absorption and gross profit.

El Dorado Facility—On May 15, 2012, the El Dorado Facility suffered significant damage when a reactor in its DSN plant exploded. As a result, the DSN plant was severely damaged and several other plants and infrastructure within the El Dorado Facility sustained various degrees of damage. Due to the extensive damage, the DSN plant is not being repaired, but will be replaced with a new 65% nitric acid plant and a nitric acid concentrator plant. The project to construct these new plants is currently expected to be completed by mid-2015. Of the three other remaining nitric acid plants, which account for approximately 80% of the nitric acid production capacity at the facility, one was restarted in June, another was restarted in July and the remaining nitric acid plant was restarted in August. The sulfuric acid plant also sustained significant damage and is expected to restart before the end of 2012.

We believe the cumulative adverse impact to operating income for the unplanned downtime at the El Dorado Facility was approximately $16 million for the first nine months of 2012 (of which $9 million related to the third quarter of 2012) including lost absorption and gross profit margins.
