LSB INDUSTRIES, INC. REPORTS RESULTS

FOR THE 2014 THIRD QUARTER

Provides Chemical Business Product Volume Guidance for 2014 Fourth Quarter

OKLAHOMA CITY, Oklahoma…November 7, 2014… LSB Industries, Inc. (“LSB”) (NYSE: LXU) today announced results for the third quarter ended September 30, 2014.

Financial Highlights of Third Quarter 2014 Compared to Third Quarter 2013

Jack Golsen, LSB’s Board Chairman and CEO, stated, “As anticipated, results for our seasonally weak third quarter were impacted by a planned extended turnaround at our Cherokee Facility and, to a lesser extent, the pull forward of planned maintenance at our Pryor and El Dorado Facilities.

“The turnaround at the Cherokee Facility was approximately 7 days longer than we had initially budgeted. However, we completed the work necessary to enable us to transition the facility to a two-year turnaround cycle, an initiative that we expect to ultimately translate into stronger operating profit and cash flow for our Chemical Business. The Cherokee Facility resumed ammonia production at the end of August and since then, has produced steadily at an average rate of approximately 500 tons per day. We expect to sustain this production level for the balance of the fourth quarter of 2014 and for 2015 as we do not have a scheduled turnaround at the Cherokee Facility until 2016.

“The maintenance at the Pryor Facility was the continuation of the extensive work we have been doing to bolster the plant’s reliability. With ammonia, urea and UAN production having run close to targeted levels since early September, we can confidently say that Pryor is in its best condition to achieve consistent production since we brought the facility online in late 2010. In fact, we anticipate full year 2014 ammonia production of approximately 165,000-175,000 tons at Pryor, nearly double that of 2013, and expect continued improvement in 2015.

“At our El Dorado Facility, we performed certain maintenance on our sulfuric acid plant that was originally scheduled for 2015. Our expansion projects underway to install a new ammonia plant, and restore and enhance nitric acid capacity, remain on budget and schedule. As we have previously discussed, El Dorado purchases ammonia as its primary feedstock, versus producing its own ammonia using natural gas, as is the case with our Pryor and Cherokee Facilities. This results in a cost disadvantage for El Dorado, a condition that we expect to persist until the ammonia plant is operational in the first quarter of 2016. Once ammonia production is underway, we forecast substantial incremental operating profit from the El Dorado Facility.”

Mr. Golsen continued, “Climate Control results were essentially in-line with the 2013 third quarter, but were up materially on a sequential basis as our shipment volumes recovered from a drop in order activity caused by the severe winter weather that impacted much of the U.S. in late 2013 and early 2014. Third quarter segment bookings remained robust and we entered the final quarter of the year with our highest backlog since November 2008, reflecting continued improvement in the commercial and institutional markets we serve. With ample plant capacity to support significant volume growth and stronger overhead absorption, combined with the operational efficiency measures we have been implementing, including LEAN, we should see margin expansion in this business as sales increase.”

“As we move toward year-end,” Mr. Golsen concluded, “We feel well positioned to deliver growth in both of our businesses in 2015 and 2016.”

Financial Position and Capital Expenditures

As of September 30, 2014, our total cash and investments were $311.1 million, including short-term investments as well as noncurrent restricted cash and investments designated for capital projects.

Total long-term debt was $459.4 million at September 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 third quarter of 2014 was $5.1 million compared to $5.4 million for the same period in 2013.

Capital expenditures were $70.8 million in the third quarter of 2014, including $50.0 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 2015, in the aggregate, are estimated to range from $388 million to $458 million, including $280 million to $315 million remaining for the El Dorado expansion projects.

Industry Perspective / Outlook

Barry Golsen, LSB’s President and COO stated, “The demand environment for nitrogen fertilizers remains solid. Last year’s corn harvest improved significantly from the previous year, and this year’s harvest is shaping up to be very strong as well, resulting in a higher stock-to-use ratio and lower forward corn prices. Corn prices have declined substantially from approximately $7.00 per bushel a year ago to approximately $3.70 per bushel currently. If corn prices continue to remain low, farmers may consider planting alternatives to corn. However, since yields per acre reached all-time highs in 2014, the farmers’ revenue per acre is not down proportionately. So despite the current lower corn prices, industry consensus points to between 86 and 88 million acres of corn to be planted in 2015, similar to this past year all benefitting our agricultural chemical business.

“With respect to our mining products, in March 2014 we announced that we had elected to not renew our exclusive agreement with Orica when the term ends in April 2015 to enable us to freely sell industrial grade ammonium nitrate (AN) to the commercial explosives market. Since that time, we have executed cost-plus contracts to supply approximately half of the annual 240,000 tons of AN previously committed to Orica, and we are pursuing similar agreements for the balance of the volume under the current Orica contract.

“Regarding our other industrial products which remain a significant part of our Chemical Business, we are encouraged that growth is forecast for the next few years for the industries we serve, particularly given the strong customer relationships we have in these end markets.

“In our Climate Control Business, leading indicators point to solid growth in commercial and institutional construction over the next three years. Notably, the September Architectural Billings Index was positive for the fifth consecutive month, reaching 2007 levels. After experiencing strong year-over-year order growth in the second and third quarters, and into October, we are seeing continued improvement in most of the major vertical markets that we serve, especially lodging, multi-family housing and education. In the near-term, we expect our fourth quarter 2014 Climate Control Business sales to exceed those of last year’s fourth quarter, which we see continuing into 2015.”

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.”

The Company’s outlook for sales volume for the fourth quarter of 2014 in its Chemical Business is as follows:

Note: Agricultural anhydrous ammonia sales exclude approximately 5,000 to 10,000 tons of intercompany sales.

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.
