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."
