Oklahoma City’s Mammoth Energy Services says it is switching accounting firms.
In a filing with the Securities and Exchange Commission, the energy company announced “the dismissal” of Grant Thornton LLP as the firm’s independent registered public accounting firm and hired Deloitte & Touche LLP.
Grant Thornton was informed of the decision on March 10 and Mammoth’s SEC filing stated that during the company’s two most recent fiscal years “there no disagreements with Grant Thornton on any matter of accounting principles or practice, financial statement disclosure or auditing scope.”
