FOR IMMEDIATE RELEASE

LSB INDUSTRIES, INC. REPORTS OPERATING RESULTS

FOR THE 2016 FOURTH QUARTER

OKLAHOMA CITY, Oklahoma…February 27, 2017… LSB Industries, Inc. (NYSE: LXU) (“LSB” or the “Company”) today announced results for the fourth quarter and full year ended December 31, 2016.

Fourth Quarter Highlights

“Our results for the fourth quarter of 2016 showed sequential improvement despite downtime that carried over from the third quarter related to previously disclosed issues,” stated Daniel Greenwell, LSB’s President and CEO. “Our financial performance during the period is reflective of efforts in 2016 to increase our production and improve on-stream rates at our three primary facilities, coupled with the incremental output from the new ammonia plant at El Dorado.”

“Our Cherokee and Pryor ammonia plants operated at on-stream rates of approximately 100% and 97%, respectively, for November and December, and both plants operated at an on-stream rate of 98% or better for the past four months. We expect this to continue throughout 2017.”

“El Dorado’s ammonia on-stream rate continues to improve with the fourth quarter of 2016 increasing over third quarter of 2016. We continued this trend into the first quarter of 2017 with on-stream rates for the first two months of 2017 increasing to 84%. We are very encouraged by the performance of our new plant as it is consistently producing at rates in excess of 1,300 tons per day which is a meaningful increase over the plant’s nameplate capacity of 1,150 tons per day. With respect to the previously disclosed issue with El Dorado’s primary nitric acid plant’s nitrous oxide abatement vessel, we completed the bypass system in mid-December and it has been operating at full rates since that time. The design of a new nitrous oxide abatement vessel is underway and we expect a new vessel to be installed and operational by the second quarter of 2018; the end date of our temporary permit.”

Mr. Greenwell continued, “Selling prices for our agricultural products remained substantially lower than the prior year fourth quarter, however late in the quarter, we did see some improvement in selling prices ahead of the spring planting season. We’ve seen that strong trend continue into the first quarter of 2017 and we expect this seasonal uplift to persist throughout the spring planting season. Still, we are anticipating selling prices of agriculture products to remain low relative to the past several years due to the new ammonia production and capacity upgrades that recently started operations or are expected to come online over the next few quarters. However, by late 2017 or early 2018, we anticipate a more sustained strengthening of pricing as the domestic and export markets absorb the new production volume.”

“Demand for our agricultural products for spring applications has been strong, with the UAN production capacity at both our Pryor and Cherokee facilities sold out through the end of April and May, respectively. Additionally, our previously outlined strategy to increase sales of high density ammonium nitrate (HDAN) is working. Sales of HDAN were up significantly in the fourth quarter versus the same period last year and we currently have a significant HDAN order book running into the second quarter of 2017. We anticipate this trend will continue and we plan to position product in our storage facilities later this year in anticipation of further growth in HDAN demand in 2018. Finally, demand for the nitric acid and ammonia for industrial markets has been increasing and we expect it will continue to rise, reflecting the ongoing moderate improvement in the U.S. economy.”

Mr. Greenwell concluded, “Overall, we are optimistic about the prospects for material year-over-year performance improvement in 2017. We’ve achieved our previously articulated SG&A savings objectives by reducing corporate overhead by more than $6 million, and believe that we can extract a similar amount of cost at the plant level over the course of this year. The refinancing actions we completed in the third quarter of 2016 provided us with increased financial flexibility and will result in a meaningful reduction in full year interest expense for the current year versus last. These factors, combined with our expectation that our facilities can sustain their current rates of production give us confidence in our ability to deliver a substantial year-over-year improvement in financial results for 2017.”

Financial Position and Capital Additions

As of December 31, 2016, our total cash position was $60.0 million. Additionally, we had approximately $35.6 million of borrowing availability under the Working Capital Revolver.

Total long-term debt, including the current portion was $420.2 million at December 31, 2016 compared to $520.4 million at December 31, 2015. In July 2016, we received net cash proceeds of approximately $351 million from the sale of the Climate Control Business (an additional $7 million of proceeds was received in October 2016). In September 2016, holders of our Senior Secured Notes agreed to allow us to redeem a portion of the Series E Redeemable Preferred and to redeem a portion of the Senior Secured Notes and all of the 12%

Senior Secured Notes. In September 2016, we used $80 million to redeem a portion of the Series E Redeemable Preferred (including accumulated dividends and participation rights value). The aggregate liquidation value of the Series E Redeemable Preferred at December 31, 2016, inclusive of accrued dividends of $22.0 million, was $161.8 million.

In October 2016, we used approximately $107 million to redeem $50 million of the 7.75% Senior Secured Notes and all $50 million of the 12% Senior Secured Notes (including accrued interest and the redemption prices). At December 31, 2016, we had $375 million of Senior Secured Notes at 8.5% and approximately $53 million of other debt outstanding. We expect annual interest going forward, on the current level of debt to be between $33 million and $35 million.

Our Working Capital Revolver Loan was undrawn at December 31, 2016. Borrowing availability, which is tied to eligible accounts receivable and inventories, was approximately $35.6 million at December 31, 2016. As a result of the sale of our Climate Control Business, in January 2017, we entered into an amended and restated loan and security agreement (“The Amendment”) with Wells Fargo Capital Finance, LLC reducing our total revolver commitments from $100 million to $50 million and extending the maturity date of the Working Capital Revolver Loan to January 17, 2022, with a springing earlier maturity date (the “Springing Maturity Date”) that is 90 days prior to August 1, 2019 (the maturity date our “Senior Secured Notes”), to the extent the Senior Secured Notes are not refinanced or repaid prior to the Springing Maturity Date.

Interest expense, net of capitalized interest, for the fourth quarter of 2016 was $9.8 million compared to $0.9 million for the same period in 2015. The capitalization of interest related to capital additions made to the El Dorado Facility ceased when the Facility’s new ammonia plant went into service in May 2016.

Capital additions were approximately $11.3 million in the fourth quarter of 2016. Planned capital additions for the first quarter of 2017, are estimated to be approximately $8 million. For the full year of 2017, total capital additions which are related to maintaining and enhancing safety and reliability at our facilities are expected to be between $30 million and $35 million. With the finalization of the El Dorado expansion and the sale of the Climate Control Business, we expect depreciation and amortization to be between $65 million and $70 million for 2017.

Volume Outlook

Our outlook for sales volumes for the full year of 2017 is as follows:

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 (loss) plus interest expense, loss on extinguishment of debt, provision for impairment, depreciation, depletion and amortization of property plant and equipment (which includes amortization of other assets and excludes interest included in amortization), less benefit for income taxes and income from discontinued operations, net of taxes. 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 (loss) to EBITDA for the periods indicated.

Non-GAAP Reconciliation (continued)

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

Adjusted operating loss, adjusted EBITDA, adjusted net loss from continuing operations applicable to common stock and adjusted loss from continuing operations per diluted share are reported to show the impact of a one-time consulting fee, start-up/commissioning costs, impairment of long-lived assets and goodwill, certain fair market value adjustments, severance, non-cash stock based compensation, non-cash (gain) 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 loss, EBITDA, net loss from continuing operations applicable to common stock and diluted loss per common share from continuing operations, are appropriate to provide additional information to investors about certain items. The following tables provide reconciliations of operating loss, EBITDA, net loss from continuing operations applicable to common stock and diluted loss from continuing operations per common share excluding the impact of the supplementary adjustments.
