Something prompted Mammoth Energy Services to drop a national accounting firm and go with another.
Mammoth’s Audit Committee of the Board of Directors approved dismissal of Deloitte & Touche LLP as the firm’s independent registered public accounting firm. It informed Deloitte of the dismissal on May 13. A company statement indicated there were no disagreements with Deloitte on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedures following the most recent fiscal year. It also stated there were no “reportable events” and the Deloitte audit report for the year “did not contain an adverse opinion or a disclaimer of opinion.”
The Audit Committee approved the engagement of Carr, Riggs & Ingram, L.L.C. (“CRI”) as its new independent registered public accounting firm. CRI’s appointment will be for the Company’s fiscal year ending December 31, 2026, and related interim periods. Mammoth said it had no contact with CRI over the past two fiscal years to influence any decision.
Mammoth is preparing to hold its annual in person meeting of stockholders on June 25 and one of the items to be considered is the ratification of the appointment of Carr, Riggs & Ingram, L.L.C. as the company’s independent registered public accounting firm for the fiscal year ending December 31, 2026.
