Mammoth Energy Services, Inc. Announces
Third Quarter 2024 Operational and Financial Results


OKLAHOMA CITY - November 1, 2024 - Mammoth Energy Services, Inc. (NASDAQ: TUSK) (“Mammoth” or the “Company”) today reported financial and operational results for the third quarter ended September 30, 2024.

Arty Straehla, Chief Executive Officer of Mammoth commented, “Softness across our Well Completion Services markets appeared to have bottomed in the third quarter, and we expect a rebound in the fourth quarter. More importantly, we were pleased to have recently received a total of $168.4 million of the $188.4 million owed to our subsidiary through the Settlement Agreement with the Puerto Rico Electric Power Authority, or PREPA. We are now debt free and have plans to invest in both our Infrastructure Services and Well Completion Services divisions over the next year. In Infrastructure Services, we will be investing in additional crews and our engineering services capabilities to better serve our customers. In our Well Completion Services division, we will be upgrading pressure pumping equipment to more efficient dual fuel Tier 4 technology. We believe this investment positions us to capitalize on rising demand as markets are anticipated to improve later next year. Now that we are debt free and have significant capital to invest into our businesses, we believe we have an excellent platform to increase shareholder value.”

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 (loss) income before depreciation, depletion, amortization and accretion expense, gains on disposal of assets, net, impairment of goodwill, stock based compensation, interest expense and financing charges, net, other (income) expense, net (which is comprised of interest on trade accounts receivable and certain legal expenses) and provision (benefit) for income taxes, further adjusted to add back interest on trade accounts receivable. The Company excludes the items listed above from net (loss) income 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 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 historic 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 tables provide a reconciliation of Adjusted EBITDA to the GAAP financial measure of net (loss) income on a consolidated basis and for each of the Company’s segments (in thousands):
