Mammoth Energy Services, Inc. files its annual report describing an integrated services portfolio spanning rental equipment, infrastructure, natural sand proppant, accommodations and directional drilling across key North American basins and fiber markets.
The company highlights a transformative settlement with Puerto Rico Electric Power Authority giving subsidiary Cobra an allowed administrative expense claim of $170.0 million plus $18.4 million of previously withheld FEMA funds, with a first installment of $150.0 million received in October 2024 and a subsequent $18.4 million payment later that month.
To reflect this settlement, Mammoth recorded a non-cash pre-tax charge of $170.7 million in 2024 to reduce its PREPA receivable from $359.1 million to the expected recovery. The company also completed four divestitures in 2025, including sales of infrastructure, hydraulic fracturing equipment and an engineering business for cash proceeds such as $108.7 million, $15.0 million and approximately $30.0 million, which are reported as discontinued operations.
Management reports a narrowed focus on rental, infrastructure, sand proppant, accommodations and drilling, with an emphasis on capital efficiency and cross-selling. As of December 31, 2025, Mammoth reports no outstanding debt and unrestricted cash of $102.0 million. Non-affiliate equity market value was approximately $70.7 million as of June 30, 2025, and common shares outstanding were 48,358,315 as of March 3, 2026.
