The price reported in Column 4 is a weighted average price. These shares were sold in multiple transactions at prices ranging from $10.00 to $10.01, inclusive. The reporting person undertakes to provide to LSB Industries, Inc. (the "Issuer"), any security holder of the Issuer, or the staff of the Securities and Exchange Commission (the "SEC"), upon request, full information regarding the number of shares sold at each separate price within the range set forth in this footnote. The sales of shares of common stock reported on this Form 4 were effected pursuant to 10b5-1 trading plans adopted by the Irrevocable Family Trusts (defined below) on September 4, 2025.; These shares are held by separate irrevocable trusts established for the benefit of the reporting person and the reporting person's children and grandchildren (collectively, the "Irrevocable Family Trusts"), of which the reporting person is the trustee. The amount shown is the aggregate number of shares held in the Irrevocable Family Trusts. No single Irrevocable Family Trust has more than one beneficiary. Because the reporting person is trustee of the Irrevocable Family Trusts, of which the beneficiaries are either the reporting person or his children or grandchildren, the reporting person is deemed to have a pecuniary interest in the Issuer's common stock held by the Irrevocable Family Trusts, pursuant to Rule 16a-8(b)(2)(ii).
