Item 4.01 Changes in Registrant’s Certifying Accountant.
(a) Dismissal of Independent Registered Public Accounting Firm.
On February 27, 2025, the Audit Committee of the Board of Directors (the “Audit Committee”) of Oil States International, Inc. (the “Company”) dismissed Ernst & Young LLP (“EY”) as the Company’s independent registered public accounting firm.
During the Company’s two most recent fiscal years ended December 31, 2024 and December 31, 2023 and during the subsequent interim period from January 1, 2025 through February 27, 2025, (i) there were no disagreements with EY on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedures that, if not resolved to EY’s satisfaction, would have caused EY to make reference to the subject matter of the disagreement in connection with its reports and (ii) there were no “reportable events” as defined in Item 304(a)(1)(v) of Regulation S-K.
The audit reports of EY on the consolidated financial statements of the Company for each of the two most recent fiscal years ended December 31, 2024 and December 31, 2023 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.
In accordance with Item 304(a)(3) of Regulation S-K, the Company provided EY with a copy of this Current Report on Form 8-K prior to its filing with the Securities and Exchange Commission (“SEC”) and requested that EY furnish it with a letter addressed to the SEC stating whether it agrees with the above statements in this Item 4.01(a). A copy of EY’s letter, dated March 4, 2025, is filed as Exhibit 16.1 to this Current Report on Form 8-K.
(b) Appointment of New Independent Registered Public Accounting Firm.
On February 27, 2025, the Audit Committee approved the engagement of Deloitte & Touche LLP (“Deloitte”) as its new independent registered public accounting firm. Deloitte’s appointment will be for the Company’s fiscal year ending December 31, 2025, and related interim periods.
During the Company’s two most recent fiscal years ended December 31, 2024 and December 31, 2023, and for the subsequent interim period through February 27, 2025, neither the Company nor anyone on its behalf consulted Deloitte regarding (i) the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on the consolidated financial statements of the Company, in connection with which neither a written report nor oral advice was provided to the Company that Deloitte concluded was an important factor considered by the Company in reaching a decision as to the 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 described in Item 304(a)(1)(v) of Regulation S-K.
