Mammoth Energy Services, Inc. reported results for the quarter ended June 30, 2025 showing a net income of $8.848 million for the quarter and $8.311 million for the six months, driven largely by discontinued operations related to the sale of its transmission, distribution and substation businesses and hydraulic fracturing equipment. Continuing operations recorded an operating loss of $36.4 million for the quarter and a net loss from continuing operations of $35.693 million, reflecting an impairment charge of $31.7 million related to natural sand proppant assets.
The company completed a T&D divestiture for aggregate proceeds of $108.7 million and sold hydraulic fracturing equipment for $15.0 million, classifying those businesses as discontinued operations. Cash and restricted cash increased to $157.3 million of continuing operations at June 30, 2025, the revolving credit facility was undrawn with $67.5 million borrowing capacity, and total equity was $262.0 million. The company maintains a large allowance for expected credit losses of $170.983 million related to prior receivable matters.
Mammoth Energy Services, Inc. filed a current report to share that it has released its operational and financial results for the second quarter ended June 30, 2025. The company issued a press release on August 8, 2025, which is included as Exhibit 99.1 to this report. The press release contains the detailed second quarter 2025 results and related commentary from management.
The company notes that the information in this results release, including Exhibit 99.1, is being furnished rather than filed under securities laws, meaning it is not automatically incorporated into registration statements unless specifically referenced.
Mammoth Energy Services, Inc. (NASDAQ: TUSK) filed an 8-K announcing the sale of all hydraulic fracturing equipment held by subsidiaries Stingray Pressure Pumping LLC and Mammoth Equipment Leasing LLC to MGB Manufacturing, LLC for $15.0 million in cash. The divested assets belong to the Company’s Well Completion segment and the transaction closed concurrently with the signing of the Equipment Purchase Agreement on 16 June 2025. Piper Sandler & Co. acted as exclusive advisor.
Because the carrying value of goodwill related to the hydraulic fracturing business now exceeds fair value, Mammoth expects to record a non-cash impairment charge of $7.7-$9.2 million in Q2 2025.
The Company also referenced its previously disclosed T&D Transaction—the April 2025 divestiture of three transmission & distribution subsidiaries—and filed unaudited pro forma condensed consolidated financial statements (Exhibit 99.1) reflecting both divestitures.
Key implications for investors:
- Immediate liquidity boost of $15 million.
- Streamlining of portfolio away from capital-intensive pressure pumping operations.
- Expected goodwill impairment nearly offsets transaction proceeds, pressuring near-term earnings but non-cash in nature.
- Future revenue and EBITDA from hydraulic fracturing will cease unless replaced by new lines or acquisitions.
