Mammoth Energy Services, Inc. Announces
Third Quarter 2023 Operational and Financial Results


OKLAHOMA CITY - November 9, 2023 - Mammoth Energy Services, Inc. (“Mammoth” or the “Company”) (NASDAQ: TUSK) today reported financial and operational results for the third quarter ended September 30, 2023.

Financial Overview for the Third Quarter 2023:

Total revenue was $65.0 million for the third quarter of 2023 compared to $107.2 million for the same quarter last year and $75.4 million for the second quarter of 2023.

Net loss for the third quarter of 2023 was $1.1 million, or $0.02 loss per diluted share, compared to net income of $7.7 million, or $0.16 per diluted share, for the same quarter last year and net loss of $4.5 million, or $0.09 loss per diluted share, for the second quarter of 2023.

Adjusted EBITDA (as defined and reconciled below) was $13.4 million for the third quarter of 2023, compared to $29.8 million for the same quarter last year and $16.4 million for the second quarter of 2023.

Arty Straehla, Chief Executive Officer of Mammoth commented, “We are pleased to have announced that we entered into a new revolving credit facility agreement and a new term loan agreement, which refinanced, in full, Mammoth’s indebtedness outstanding under our previous revolving credit facility. We believe these new agreements will provide Mammoth with a strong base of liquidity for years to come.

“Third quarter results, as expected, were challenged by the persistence of demand and activity pressures, in particular in natural gas basins, that negatively impacted our pressure pumping fleet utilization, thus impacting our overall performance. These market pressures that began earlier this year are largely attributable to commodity price fluctuations and delayed customer schedules. In response, we continue to closely manage our costs. Despite the softness we’ve experienced this year, we are now seeing encouraging signs of increasing activity and customer planning for 2024. We are also pleased with the improving line of sight for the next few quarters, and we expect an improvement in frac fleet counts in 2024.”

Straehla added, “During and subsequent to the end of the third quarter, we were pleased to have received $11.4 million from PREPA, bringing the total payments received this year from PREPA to $22.2 million. While this only represents a portion of what is still owed to us for the work completed by our subsidiary Cobra, we continue to pursue payment of the outstanding amounts owed by PREPA, including the associated interest that has accrued and is continuing to accrue.”

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, impairment of goodwill, gains on disposal of assets, net, stock based compensation, interest expense, 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):
