CORPORATE GOVERNANCE AND BOARD COMPOSITION

Company to Add Five New Independent Directors: Xxxxx Xxxxxxx,

Xxxxxx Xxxxxx, Xxxxxx Xxxxxxx, Xxxxxxx Xxxxxx and Xxxx Xxxxx

Announces Intention to Separate Chemicals and Climate Control Businesses

and to Explore MLP Structure for Chemicals Business Following Completion of El Dorado Facility Expansion in 2016, Subject to Market Conditions and Board Approval

New Lead Independent Director Appointed and Independent Board Committee

to Oversee Search for President of Chemicals Business

OKLAHOMA CITY – April 27, 2015 – LSB Industries, Inc. (NYSE: LXU) (“LSB” or “the Company”), a manufacturer of chemical products for the agricultural, mining and industrial markets and a leading manufacturer of commercial and residential climate control products, today announced that it has elected Xxxxx X. Massimo, Xxxxxx X. Xxxxxx, Xxxxxxx Xxxxxx, Xxxxxx X. Xxxxxxx and Xxxx X. Xxxxx to its Board of Directors. These five new independent directors, as well as incumbent directors Xxxxxxx Xxxxxxx and Xxxxx Xxxxxx, will stand for re-election to LSB’s Board of Directors at the Company’s 2015 Annual Meeting of Stockholders. Messrs. Massimo and Xxxxxx will fill the vacancies created by the resignations, effective today, of Xxxx Xxxxxxx and Xxxxxx Xxxxx.

If re-elected by LSB’s stockholders at the 2015 Annual Meeting, Xx. Xxxxxxx and Messrs. Roedel, Sanders, Golsen and White will have terms expiring at the 2018 Annual Meeting and Messrs. Massimo and Xxxxxx will join the class of directors with terms expiring at the 2017 Annual Meeting. With these appointments, the LSB Board will expand to 13 directors, 11 of whom are independent and 9 of whom were appointed in the last 24 months.

“We are pleased to have reached this agreement with Starboard on the composition of the Board,” said Xxxxx Xxxxxx, Chief Executive Officer of LSB. “On behalf of the entire Board, I would like to thank Xxxx Xxxxxxx and Xxxxxx Xxxxx for their dedicated service and contributions to the Board and LSB. We look forward to working with the new independent directors.”

Xx. Xxxxxx continued, “We remain committed to enhancing stockholder value, and we believe the improvements we are making to increase capacity and upgrade facilities will position LSB for enhanced growth and profitability. We are therefore pleased to announce our intention, once our El Dorado facility expansion projects have been completed and brought online in 2016, to the extent market conditions allow and subject to Board approval, to separate the Company’s Chemicals business from its Climate Control business and to explore an MLP structure for the Chemicals business.”

In connection with today’s announcement, LSB has entered into an agreement with Starboard Value LP (“Starboard”), which beneficially owns approximately 7.6% of the Company’s outstanding shares. Under the agreement, Starboard has agreed, among other things, not to solicit proxies or participate in any “withhold” campaign in connection with the 2015 Annual Meeting and to vote its shares in support of all of the Company’s director nominees. Starboard has also agreed to vote all of its shares in accordance with the Board’s recommendation with respect to the Company’s say-on-pay proposal, subject to the recommendation of Institutional Shareholder Services.

In addition, the responsibilities of the Strategic Committee of the Board, which was formed in June 2014, will be expanded to include an evaluation of Company’s corporate governance and management structure, related party transactions and any other governance practices of the Company deemed appropriate by the Strategic Committee. The Strategic Committee will make recommendations to the Board based on its findings, and the Company intends to announce the Board’s decisions with respect to these recommendations concurrent with its second quarter 2015 earnings release.

The Company also agreed to form an independent Board Committee to oversee the Company’s previously announced executive search for a President of the Chemicals business; this committee will consist of Messrs. Xxxxxx X. Greenwell, Sanders, Xxxxxx and White. As previously announced the company is working with executive search firm Xxxxxxx Xxxxxx to assist in the search.

The Company also announced that Xx. Xxxxxxxxx was elected Lead Independent Director.

Xxxx Xxxxx, CEO of Starboard, stated, “We are pleased that we have been able to continue to work constructively with LSB to reach this agreement, and we look forward to meaningful value creation. We believe that strengthening the Board with highly experienced and independent directors will support the Company in executing on its plans to drive sales growth and profitability for the benefit of all shareholders. Xxxxx Xxxxxxx, Xxxxxx Xxxxxx, and Xxxx Xxxxx bring substantial experience in the Chemicals and Fertilizer industries, which should help LSB as it continues its progress in turning around and significantly expanding this business.
