The Audit Committee (the "Committee") of the Board of Directors of LSB Industries, Inc. (the "Company") conducted a competitive selection process to determine the Company's independent registered public accounting firm for the fiscal year ending December 31, 2026. The Committee invited several public accounting firms to participate in this process, including Ernst & Young LLP ("EY"), the Company's independent registered public accounting firm for the fiscal year ended December 31, 2025.

As a result of this process, following the review and evaluation of proposals from participating firms, on March 4, 2026, the Committee approved the engagement of PricewaterhouseCoopers LLP ("PwC") as the Company's independent registered public accounting firm for the fiscal year ending December 31, 2026, subject to completion of PwC's standard client acceptance procedures and execution of an engagement letter. On the same date, the Committee approved the dismissal of EY as the Company's independent registered public accounting firm, effective immediately, and informed EY of such dismissal.

The reports of EY on the Company's consolidated financial statements for the fiscal years ended December 31, 2025 and 2024 did not contain an adverse opinion or a disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope or accounting principles.

During the fiscal years ended December 31, 2025 and 2024, and the subsequent interim period through March 4, 2026, (i) there were no disagreements, as defined in Item 304(a)(1)(iv) of Regulation S-K, with EY on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of EY, would have caused EY to make reference to the subject matter of the disagreements in connection with EY's reports on the Company's consolidated financial statements for such period and (ii) there were no "reportable events," as defined in Item 304(a)(1)(v) of Regulation S-K.

The Company provided EY with a copy of the disclosures in this Current Report on Form 8-K and requested that EY furnish the Company with a letter addressed to the Securities and Exchange Commission stating whether or not it agrees with the Company's statements herein. A copy of such letter, which is dated March 5, 2026, is attached as Exhibit 16.1 to this Current Report on Form 8-K.

During the fiscal years ended December 31, 2025 and 2024, and the subsequent interim period through March 4, 2026, neither the Company nor anyone acting on the Company's behalf consulted with PwC regarding (i) the application of accounting principles to any specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on the Company's consolidated financial statements, and neither a written report nor oral advice was provided to the Company that PwC concluded was an important factor considered by the Company in reaching a decision as to any accounting, auditing or financial reporting issue or (ii) any matter that was either the subject of a "disagreement," as defined in Item 304(a)(1)(iv) of Regulation S-K, or a "reportable event," as defined in Item 304(a)(1)(v) of Regulation S-K.
