**Mammoth Energy Services, Inc. Announces** 

**Third Quarter 2025 Operational and Financial Results**

OKLAHOMA CITY, OK – October 31, 2025 – Mammoth Energy Services, Inc. (NASDAQ: TUSK) ("Mammoth" or the "Company") today reported financial and operational results for the third quarter ended September 30, 2025.

Mark Layton, Chief Financial Officer of Mammoth commented, "Mammoth continued to make meaningful progress this quarter in advancing our transformation and strengthening the foundation of the Company. During the quarter, we completed the divestiture of our Piranha assets within the Sand segment — another deliberate step in pruning the portfolio and exiting lower-return assets — while continuing to deploy capital in our aviation platform, which remains a high-return and scalable growth area for Mammoth. These actions reflect our disciplined approach to building a leaner, more efficient organization centered on consistent cash generation and long-term value creation.

"We closed the quarter with approximately $153.4 million in total liquidity and no debt, providing us with exceptional financial flexibility to navigate market conditions and pursue opportunities that align with our return thresholds. With this balance sheet strength and continued focus on operational execution, we believe Mammoth is well-positioned to build durable value and deliver sustainable performance through cycles."

**Financial Overview for the Third Quarter 2025:**

Total revenue from continuing operations was $14.8 million for the third quarter of 2025 compared to $17.1 million for the third quarter of 2024 and $16.4 million for the second quarter of 2025.

Net loss from continuing operations for the third quarter of 2025 was $12.1 million, or $0.25 per diluted share, compared to $8.9 million, or $0.18 per diluted share, for the third quarter of 2024 and $35.7 million, or $0.74 per diluted share, for the second quarter of 2025.

Adjusted EBITDA from continuing operations (as defined and reconciled in the tables below) was ($4.4) million for the third quarter of 2025, compared to ($2.9) million for the third quarter of 2024 and ($2.8) million for the second quarter of 2025.

**Infrastructure Services**

Mammoth's infrastructure services segment contributed revenue of $4.8 million for the third quarter of 2025 compared to $4.4 million for the third quarter of 2024 and $5.4 million for the second quarter of 2025. The increase in revenue was primarily due to an increase in fiber optic activity.

**Rental Services**

Mammoth's rental services segment contributed revenue (inclusive of inter-segment revenue) of $2.8 million for the third quarter of 2025 compared to $2.2 million for the third quarter of 2024 and $3.1 million for the second quarter of 2025. The average number of pieces of equipment rented to customers was 286 for the third quarter of 2025 compared to 249 during the third quarter of 2024 and 296 during the second quarter of 2025. Additionally, during the second quarter of 2025, the Company expanded its aviation rental offerings, which contributed to the increased revenue.

Mammoth's natural sand proppant services segment contributed revenue of $2.7 million for the third quarter of 2025 compared to $4.9 million for the third quarter of 2024 and $5.4 million for the second quarter of 2025. In the third quarter of 2025, the Company sold approximately 122,000 tons of sand at an average sales price of $18.26 per ton compared to sales of approximately 163,000 tons of sand at an average sales price of $22.89 per ton during the third quarter of 2024. In the second quarter of 2025, sales were approximately 242,000 tons of sand at an average price of $21.41 per ton.

**Accommodation Services**

Mammoth's accommodation services segment contributed revenue of $2.3 million for the third quarter of 2025 compared to $2.9 million for the third quarter of 2024 and $1.8 million for the second quarter of 2025.

**Drilling Services**

Mammoth's drilling services division contributed revenue of $2.3 million for the third quarter of 2025 compared to $1.6 million for the third quarter of 2024 and $0.7 million for the second quarter of 2025. The increase in drilling services revenue for the third quarter of 2025 compared to the second quarter of 2025 is primarily attributable to an increase in utilization.

Selling, general and administrative ("SG&A") expense was $5.2 million for the third quarter of 2025 compared to $6.8 million for the third quarter of 2024 and $5.3 million for the second quarter of 2025. The decrease is primarily due to a decrease in legal fees.

RECONCILIATION OF NON-GAAP FINANCIAL MEASURES

**Adjusted EBITDA**

Adjusted EBITDA is a supplemental non-GAAP financial measure that is used by management and external users of the Company's financial statements, such as industry analysts, investors, lenders and rating agencies. Mammoth defines Adjusted EBITDA as net income or loss from continuing operations before depreciation, depletion, amortization and accretion, gains on disposal of assets, net, impairment of long-lived assets, stock based compensation, interest (income) expense and financing charges, other expense, net (which is comprised of interest on trade accounts receivable and certain legal expenses) and (benefit) provision for income taxes, further adjusted to add back interest on trade accounts receivable. The Company excludes the items listed above from net (loss) income from continuing operations in arriving at Adjusted EBITDA because these amounts can vary substantially from company to company within the energy service industry depending upon accounting methods and book values of assets, capital structures and the method by which the assets were acquired. Adjusted EBITDA should not be considered as an alternative to, or more meaningful than, net (loss) income from continuing operations or cash flows from operating activities as determined in accordance with GAAP or as an indicator of Mammoth's operating performance or liquidity. Certain items excluded from Adjusted EBITDA are significant components in understanding and assessing a company's financial performance, such as a company's cost of capital and tax structure, as well as the historical costs of depreciable assets. Mammoth's computations of Adjusted EBITDA may not be comparable to other similarly titled measures of other companies. The Company believes that Adjusted EBITDA is a widely followed measure of operating performance and may also be used by investors to measure its ability to meet debt service requirements.

The following table provides a reconciliation of Adjusted EBITDA to net loss from continuing operations, the most directly comparable GAAP financial measure (in thousands):
