FOR IMMEDIATE RELEASE

LSB INDUSTRIES, INC. REPORTS CONTINUED IMPROVEMENT IN RESULTS

FOR THE 2014 SECOND QUARTER

OKLAHOMA CITY, Oklahoma… August 8, 2014… LSB Industries, Inc. (“LSB”) (NYSE: LXU) today announced results for the second quarter ended June 30, 2014.

Financial Highlights of Second Quarter 2014 Compared to Second Quarter 2013

Jack Golsen, LSB’s Board Chairman and CEO, stated, “We delivered an increase in profitability as a result of improved performance by our Chemical Business, despite a drop in average sales prices. Our investments and work to achieve greater reliability at our Pryor Facility are beginning to pay off as the facility produced ammonia at an acceptable rate of approximately 650 tons per day. At our El Dorado Facility, we remain on schedule and on budget with our two expansion projects, which we expect to generate material incremental operating profit starting in 2016. Results in our Climate Control Business were below what we know we are capable of achieving, as the decline in both sales and profits was reflective of lower order intake during late 2013 and early 2014 resulting in part due to the severe winter weather that affected business activity across much of the U.S. However, second quarter Climate Control bookings and backlog rose significantly, reaching their highest levels since the third quarter of 2008, which points to higher segment sales and profitability for the balance of the year compared to the first half of this year. Overall, with our Chemical facilities operating at consistent production rates and our Climate Control backlog at a multi-year high and despite planned turnarounds in the third quarter, we expect improved results for the second half of 2014, compared to the second half of 2013 when excluding the effect of insurance recoveries.”

Financial Position and Capital Expenditures

As of June 30, 2014, our total cash and investments were $389.1 million, including cash, cash equivalents, and short-term investments as well as noncurrent restricted cash, cash equivalents and investments designated for capital projects.

Total long-term debt was $460.3 million at June 30, 2014 compared to $463.0 million at December 31, 2013 and our $100 million Working Capital Revolver Loan remains undrawn. Interest expense, net of capitalized interest, for the second quarter of 2014 was $5.7 million compared to $0.5 million for the same period in 2013 reflecting the issuance of $425 million of the 7.75% Senior Secured Notes in August 2013.

Capital expenditures were $61.8 million in the second quarter of 2014, including $40.9 million relating to the expansion projects at our El Dorado Facility, which include a 1,150 ton per day anhydrous ammonia production plant; a new 1,100 ton per day 65% strength nitric acid plant and concentrator; and other support infrastructure. Planned capital expenditures for the remainder of 2014 and for 2015 are estimated to range from $392 million to $515 million, including $274 million to $344 million remaining for the El Dorado expansion projects.

Industry Perspective / Outlook

Barry Golsen, LSB’s President and COO stated, “In our Chemical Business, the fundamentals for the nitrogen fertilizers we produce continue to be positive. Gross margins per ton sold in the first half of 2014, continue to be strong but were lower than the prior year, due in part to a spike in natural gas feedstock costs during the winter and early spring. Natural gas prices have moderated in recent weeks, a trend, that if sustained, would be a benefit to our Chemical Business profitability in the second half. Last year’s corn harvest improved significantly from the previous year, resulting in a higher stock-to-use ratio and lower forward corn prices, and is shaping up to be very much the same this year. As a result, corn prices have declined substantially from approximately $7.00 per bushel a year ago to slightly below $4.00 currently. If corn prices continue to remain low this could put pressure on farmers to consider planting alternatives to corn. However, industry consensus is that approximately 90 million acres of corn will be planted in 2015, despite the current lower corn prices, all benefitting our agricultural chemical business. Industrial products remain a significant part of our Chemical Business and we are pleased to see that growth is forecast for the next few years for the industries we serve.

“In our Climate Control Business, leading indicators point to solid growth in commercial and institutional construction, as well as residential housing starts, over the next three years. However, the rate of recovery in the commercial and institutional sectors, which typically account for more than 80% of our Climate Control Business sales, is still lower than previously anticipated. We continue to anticipate an improvement in all the major vertical markets that we serve, especially lodging, multi-family housing and education, and we are beginning to see increased demand, as evidenced by our strong order levels in the second quarter and into July. However, we are also seeing equipment delivery schedules delayed, due to project construction schedule changes. More specifically to our business, in aggregate, we expect our Climate Control Business sales to increase in the second half of 2014 compared to the second half of 2013 due to higher sales of LSB branded products. This is despite the previously announced loss of the Carrier heat pump business. Finally, in advance of a more widespread recovery, we have been investing in our Climate Control operations, implementing operating efficiency measures such as LEAN, which we expect to result in improved profitability as volume increases.”

Mr. Golsen concluded, “In summary, we see favorable dynamics emerging for both our Chemical and Climate Control end markets. Our focus remains on solid execution across all of our facilities and investing to enhance the economics of our operations in order to drive sales and profit growth and increased value for shareholders in years to come.”

Non-GAAP Reconciliation

(unaudited)

This news release includes the measure “EBITDA,” which is deemed a “non-GAAP financial measure” under the rules of the Securities and Exchange Commission, including Regulation G. This non-GAAP measure is calculated using GAAP amounts in our consolidated financial statements. EBITDA has limitations and should not be considered in isolation or as a substitute for net income, operating income, cash flow from operations or other consolidated income or cash flow data prepared in accordance with GAAP. Because not all companies use identical calculations, this presentation of EBITDA may not be comparable to a similarly titled measure of other companies.

EBITDA Reconciliations

EBITDA is defined as net income plus interest expense, depreciation, depletion and amortization of property plant and equipment, amortization of other assets, less interest included in amortization, plus provision for income taxes plus loss from discontinued operations. We believe that certain investors consider EBITDA a useful means of measuring our ability to meet our debt service obligations and evaluating our financial performance. The following table provides a reconciliation of net income to EBITDA for the periods indicated.

Note: Please refer to the Company’s Form 10-Q for the quarter ended June 30, 2014 for discussions concerning significant items that impacted the periods shown above.
