Amendment Description LSB Industries, Inc. (the “Company”) is filing this Amendment No. 1 (this “Amendment No. 1”) to its Annual Report on Form 10-K for the fiscal year ended December 31, 2021, which was originally filed with the Securities and Exchange Commission (“SEC”) on February 24, 2022 (the “Original Form 10-K”) as an exhibits-only filing that updates, amends and supplements Part IV, Item 15 of the Original Form 10-K for the purpose of filing certain exhibits that were inadvertently omitted from the Original Form 10-K and removing certain exhibits that are no longer required to be included therein that were inadvertently included in the Original Form 10-K. In addition, as required by Rule 12b-15 under the Securities and Exchange Act of 1934, as amended, this Amendment No. 1 includes new Exhibits 31.1 and 31.2, certifications of our Principal Executive Officer and Principal Financial Officer, pursuant to Section 302 of the Sarbanes-Oxley Act of 2002, and new Exhibits 32.1 and 32.2, certifications of our Principal Executive Officer and Principal Financial Officer, pursuant to Section 906 of the Sarbanes-Oxley Act of 2002. This Amendment No.1 does not affect any other parts of, or exhibits to, the Original Form 10-K, and those unaffected parts or exhibits are not included in this Amendment No. 1. Except as expressly stated in this Amendment No. 1, the Original Form 10-K continues to speak as of the date of the original filing of the Original Form 10-K, and the Company has not updated the disclosure contained in this Amendment No. 1 to reflect events that have occurred since the filing of the Original Form 10-K. Accordingly, this Amendment No. 1 must be read in conjunction with the Company’s other filings made with the SEC subsequent to the filing of the Original Form 10-K, including amendments to those filings, if any.
