LSB INDUSTRIES INC

Amendment to Second Amended and Restated Bylaws

On December 17, 2024, the Board of Directors approved an amendment (the “Bylaws Amendment”) to the Second Amended and Restated Bylaws of the Company, effective as of such date. The Bylaws Amendment modified the provision relating to the removal of directors by removing the conditions for which cause for removal would be deemed to exist.

Prior to the Bylaws Amendment, the then-existing bylaws provided that cause for removal of a director would be deemed to exist only if the director being removed had been convicted of a felony by a court of competent jurisdiction or had been adjudged by a court of competent jurisdiction to be liable for intentional misconduct or knowing violation of law in the performance of such director’s duty to the Company and, in each case, such adjudication was no longer subject to direct appeal.

A copy of the Second Amended and Restated Bylaws, as amended by the Bylaws Amendment, is attached to this Annual Report on Form 10-K as Exhibit 3(ii).1.
