Business Context and Reporting Period
Company: Mammoth Energy Services, Inc. (TUSK)
Filing Type: Form 10-Q (Unaudited)
Period: Quarter and nine months ended September 30, 2025
Overview: Mammoth provides rental, infrastructure, natural sand proppant, accommodation, and drilling services to the oil, natural gas, and utility industries.

Material Changes vs. Prior Period
- Revenue Decline: Q3 2025 revenue decreased 13% year-over-year, driven by a 45% drop in natural sand proppant revenue (due to lower volumes and pricing) and a 21% decline in accommodation services (lower utilization). This was partially offset by growth in rental services (+27%) and drilling services (+44%).
- Impairment Charges: The Company recognized a $31.7 million impairment of long-lived assets in the nine months ended September 30, 2025, related to natural sand proppant assets reclassified as held for sale.
- Discontinued Operations: The Company recorded a net loss of $0.6 million from discontinued operations in Q3 2025, compared to a $15.2 million loss in Q3 2024. For the nine months, discontinued operations generated $45.0 million in net income, primarily due to gains on the sale of infrastructure and pressure pumping assets.
- Cost Structure: Selling, general, and administrative (SG&A) expenses decreased significantly in 2025 compared to 2024, as the prior year included a massive $89.2 million charge related to the PREPA settlement agreement.
- Liquidity Improvement: Cash and cash equivalents increased to $98.2 million from $60.8 million at year-end 2024, bolstered by proceeds from asset sales and the release of restricted cash collateral in October 2025.
Guidance, Outlook, and Risks
- Q4 2025 Outlook: Management expects an Adjusted EBITDA loss from continuing operations of $2.0 million to $3.0 million. Cash outflow from discontinued operations is expected to range from $1.0 million to $2.0 million.
- Capital Expenditures: Full-year 2025 capital expenditures are estimated at approximately $45.5 million, primarily focused on aviation and equipment rental expansion.
- PREPA Settlement: As of September 30, 2025, the Puerto Rico Electric Power Authority (PREPA) owes the Company $20.0 million, payable within seven days of the effective date of PREPA's bankruptcy plan. A $18.4 million letter of credit securing this obligation was released in October 2025, returning $19.3 million in cash collateral to the Company.
- Key Risks:
- Commodity Volatility: Oil and natural gas prices and OPEC+ actions directly impact customer capital expenditures and demand for proppant and drilling services.
- Customer Concentration: Significant receivables remain tied to specific customers, including the outstanding PREPA balance.
- Legal Proceedings: Ongoing litigation regarding construction excise taxes in Puerto Rico and other matters could result in additional liabilities.
- Asset Disposal: The Company is actively marketing natural sand proppant assets; delays in sale could impact liquidity and asset valuation.
Investor Verification Checklist
- PREPA Payment Status: Verify the timeline for the remaining $20.0 million payment from PREPA and the status of their bankruptcy plan of adjustment.
- Asset Sales Progress: Monitor the sale of natural sand proppant assets (Piranha Proppant) and drilling rigs currently classified as "held for sale."
- Proppant Segment Viability: Assess the sustainability of the natural sand proppant segment given the 45% revenue drop in Q3 and the $31.7 million impairment charge.
- Capital Allocation: Review the execution of the $45.5 million capital expenditure plan, specifically the expansion of the aviation rental fleet.
- Debt Covenants: Confirm continued compliance with the revolving credit facility covenants, particularly the fixed charge coverage ratio, though no financial covenant period was in effect as of the filing date.
