Item 4.01 Changes in Registrant's Certifying Accountant.
On December 1, 2023, upon the completion of a comprehensive selection process, Compass Minerals International, Inc. (the “Company”), at the direction of the Board of Directors of the Company (the “Board”), dismissed its current independent registered public accounting firm, Ernst & Young LLP (“Ernst & Young”).
Ernst & Young’s reports on the Company’s consolidated financial statements for the fiscal years ended September 30, 2022 and September 30, 2023, do not contain any adverse opinion or disclaimer of opinion, and they are not qualified or modified as to uncertainty, audit scope, or accounting principles.
During the fiscal years ended September 30, 2022 and September 30, 2023 and the subsequent interim period through December 1, 2023, there were (i) no disagreements with Ernst & Young on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, any of which, if not resolved to Ernst & Young’s satisfaction, would have caused it to make reference to the subject matter of any such disagreement in connection with its reports for such years and (ii) no “reportable events” requiring disclosure pursuant to paragraph (a)(1)(v) of Item 304 of Regulation S-K, except concerning the material weaknesses in the Company’s internal control over financial reporting disclosed in Item 4 of the Company’s Quarterly Reports on Form 10-Q for the quarterly periods ended December 31, 2022, March 31, 2023 and June 30, 2023, and reported in Item 9A of the Company’s Annual Report on Form 10-K for the fiscal year ended September 30, 2022.
In accordance with Item 304(a)(3) of Regulation S-K, the Company has provided Ernst & Young a copy of the disclosures it is making in this Current Report on Form 8-K prior to filing with the SEC and requested that Ernst & Young furnish the Company with a letter addressed to the SEC stating whether or not Ernst & Young agrees with the above statements. A copy of that letter, dated December 7, 2023, is filed as Exhibit 16.1 to this Current Report on Form 8-K.
On December 6, 2023, at the direction of the Board, the Company engaged KPMG LLP, (“KPMG”) as the Company’s new independent registered public accounting firm. KPMG’s appointment is for the Company’s fiscal year ending September 30, 2024, and related interim periods.
During the fiscal years ended September 30, 2022, and September 30, 2023, and the subsequent interim period through December 6, 2023, neither the Company nor anyone on its behalf has consulted with KPMG regarding (i) the application of accounting principles to a specific transaction, either completed or proposed, or the type of audit opinion that might be rendered on the Company’s financial statements, where either a written report or oral advice was provided to the Company that KPMG concluded was an important factor considered by the Company in reaching a decision as to the accounting, auditing or financial reporting issue, (ii) any matter that was the subject of a disagreement within the meaning of Item 304(a)(1)(iv) of Regulation S-K and the related instructions to item 304 of Regulation S-K or (iii) any reportable event within the meaning of Item 304(a)(1)(v) of Regulation S-K.
