FOR IMMEDIATE RELEASE

LSB INDUSTRIES, INC. REPORTS OPERATING RESULTS

FOR THE 2016 SECOND QUARTER

OKLAHOMA CITY, Oklahoma…August 8, 2016… LSB Industries, Inc. (NYSE: LXU) (“LSB” or the “Company”) today announced results from continuing operations of the chemical business for the second quarter ended June 30, 2016.

Second Quarter Highlights

“We achieved two major milestones during the second quarter that make us very optimistic about our Company’s future,” stated Daniel Greenwell, LSB’s President and CEO. “First, we completed and brought online the new 375,000 tons per year ammonia plant at our El Dorado Facility. With the addition of ammonia production, El Dorado’s financial performance should improve in the second half of 2016 as a result of significantly lower feedstock costs, along with a greater overall volume of ammonia to upgrade to other products and to sell as part of our previously announced ammonia offtake agreement. Secondly, we closed the sale of our Climate Control Business to NIBE Industrier AB for $364 million which will allow us to deleverage, reduce our overall cost of capital and focus on improving the financial and operational performance of our Chemical Business.”

“Turning to our second quarter 2016 financial performance, results for our chemical operations declined relative to the prior year quarter due largely to lower selling prices for our agricultural products and El Dorado ammonia plant start-up costs. While the spring nitrogen fertilizer application was strong resulting in robust demand for our fertilizer products, pricing in the second quarter was relatively low compared to the last several years due to lower commodity prices for grains and anticipated capacity expansions for nitrogen fertilizer facilities throughout the U.S.”

“Our industrial end markets remain solid given the continued gradual improvement in the U.S. economy. However, we do not anticipate meaningful recovery of sales to mining customers. Clearly, tough times

continue for coal mining companies in the U.S., both from commodity price and regulatory standpoints, with little relief in sight. As a result, we are working on shifting the capacity at El Dorado previously used to make LDAN for mining applications towards HDAN for agricultural use in order to fully leverage our new ammonia plant at that facility. We do however, see LDAN as an important market for us to continue to serve.”

“In addition to our accomplishments at El Dorado, we were very pleased with the performance of our other facilities during the second quarter. Our Pryor Facility has made significant improvements as we achieved an ammonia on-stream rate of 96% for the three-month period compared to 92% in the first quarter of 2016 and 86% in the second quarter of 2015. Our Cherokee Facility continues to run very well with an ammonia on-stream rate of 100% for the period compared to 96% in the first quarter of 2016 and 94% in the second quarter of 2015. We expect continued consistent production for the balance of 2016 post our turnarounds at Pryor and Cherokee, as we continue our focus on the further implementation of enhanced reliability programs at all of our facilities.”

With respect to sales of Industrial, Mining and Other Chemical Products, the following table indicates the volumes sold of our major products:

Financial Position and Capital Additions

As of June 30, 2016, our total cash and investments were $22.8 million.

Capital additions were approximately $46.4 million in the second quarter of 2016, including $40.8 million relating to the expansion projects at our El Dorado Facility. Planned capital additions for the remainder of 2016, in the aggregate, are estimated to be in the range of $25 million to $30 million. Beginning in 2017, annual maintenance capital additions for our facilities are expected to be between $40 million to $50 million. In addition, we expect to incur approximately $8 million in total turnaround expenses at our Cherokee and Pryor facilities during the third quarter 2016. With the finalization of the El Dorado expansion and the sale of the Climate Control Business, we expect consolidated depreciation and amortization to be $60 million to $65 million in 2016 and $70 million to $75 million in 2017.

Total long-term debt, including the current portion was $559.6 million at June 30, 2016 compared to $520.4 million at December 31, 2015. Borrowings on our Working Capital Revolver Loan, included in the current portion at June 30, 2016 were $30.9 million. Borrowing availability, which is tied in to eligible accounts receivable and inventories, was $38 million at June 30, 2016. However, upon closing of the sale of our Climate Control Business, on July 1, 2016, the full outstanding balance on our revolver was repaid. Based on remaining chemical related accounts receivable and inventories, our borrowing availability after repayment of the $30.9 million remained at approximately $38 million. Interest expense, net of capitalized interest, for the second quarter of 2016 was $6.4 million compared to $2.2 million for the same period in 2015. The capitalization of interest related to investments in the El Dorado ammonia plant ceased when the plant went into service in May 2016, resulting in an increase in interest expense during the quarter. Annual interest going forward, on the current level of debt should be approximately $45 million.

The aggregate liquidation value of preferred stock was $227.3 million, inclusive of accrued dividends at June 30, 2016 of $17.3 million. On April 1, 2016 we successfully refinanced our $12 million promissory note related to our Marcellus Shale assets. Furthermore, we received the remaining $5 million in financing related to the El Dorado ammonia storage tank in May 2016.

Non-GAAP Reconciliation

This news release includes certain “non-GAAP financial measures” under the rules of the Securities and Exchange Commission, including Regulation G. These non-GAAP measures are calculated using GAAP amounts in our consolidated financial statements.

EBITDA Reconciliation

EBITDA is defined as net income plus interest expense, depreciation, depletion and amortization of property plant and equipment (which includes amortization of other assets and excludes interest included in amortization), plus provision for income taxes less income 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. 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. The following table provides a reconciliation of net income to EBITDA for the periods indicated.

Non-GAAP Reconciliation (continued)

Adjusted Operating Income, EBITDA, Adjusted Net Income (Loss) from continuing operations applicable to Common Stock and Adjusted Income (Loss) from continuing operations per Diluted Share

Adjusted operating income, adjusted EBITDA, adjusted net income (loss) from continuing operations applicable to common stock and adjusted income (loss) from continuing operations per diluted share are reported to show the impact of a one-time consulting fee, start-up/commissioning costs, certain fair market value adjustments, non-cash stock based compensation, non-cash loss on disposal of property, plant, and equipment, Delaware unclaimed property liability, and life insurance recovery. We believe that the inclusion of supplementary adjustments to operating income, EBITDA, net income (loss) from continuing operations applicable to common stock and diluted income per common share from continuing operations, are appropriate to provide additional information to investors about certain items. The following tables provide reconciliations of operating income (loss), EBITDA, net income (loss) from continuing operations applicable to common stock and diluted income (loss) from continuing operations per common share excluding the impact of the supplementary adjustments.

Agricultural Sales Price Reconciliation

The following table provides a reconciliation of total agricultural sales as reported under GAAP in our consolidated financial statement reconciled to “net back” sales which is calculated as sales less freight expenses. We believe this provides a relevant industry comparison among our peer group.
