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


OKLAHOMA CITY - August 9, 2024 - Mammoth Energy Services, Inc. (“Mammoth” or the “Company”) (NASDAQ: TUSK) today reported financial and operational results for the second quarter ended June 30, 2024.

Financial Overview for the Second Quarter 2024:
Total revenue was $51.5 million for the second quarter of 2024 compared to $43.2 million for the first quarter of 2024.

Net loss for the second quarter of 2024 was $156.0 million, or $3.25 loss per diluted share, compared to net loss of $11.8 million, or $0.25 loss per diluted share, for the first quarter of 2024.

Adjusted EBITDA (as defined and reconciled below) was ($160.7) million for the second quarter of 2024 compared to $4.5 million for the first quarter of 2024. During the second quarter of 2024, the Company recognized expense of $170.7 million related to the settlement between Mammoth’s subsidiary Cobra Acquisitions LLC (“Cobra”) and the Puerto Rico Electric Power Authority (“PREPA”). Excluding this non-recurring expense and interest income previously accrued on the receivable with PREPA, Adjusted EBITDA would have been ($0.3) million for the second quarter of 2024 compared to ($6.0) million for the first quarter of 2024.

Settlement Agreement
As previously announced, on July 22, 2024, Mammoth’s subsidiary Cobra entered into a release and settlement agreement to settle all outstanding matters between Cobra and PREPA (the “Settlement Agreement”). As a result of the Settlement Agreement, the Company expects to receive $188.4 million in total settlement proceeds. During the second quarter of 2024, the Company recorded a non-cash, pre-tax charge of approximately $170.7 million, of which $89.2 million was charged to credit loss expense, which is included in “selling, general and administrative” and $81.5 million was charged to interest on delinquent accounts receivable, which is included in “other income, net” in relation to the Settlement Agreement.

Arty Straehla, Chief Executive Officer of Mammoth commented, “We are pleased to report sequential improvement in our second quarter results, compared to the first quarter, despite continued challenges that persist due to industry activity softness, especially in the natural gas basins that we operate, constraining our Well Completion Services division and other oilfield services. Our Infrastructure Services business continues to perform well and is demonstrating growth both sequentially and year over year. As we enter the second half of the year, our teams across the organization remain focused on efficient and effective cost management to align with the activity levels of our customers. We enter the second half of the year with an undrawn revolver and cash on the balance sheet, as well as a recently announced resolution with PREPA. With the anticipated collection of the PREPA receivable as a result of the Settlement Agreement, we believe Mammoth will be better positioned to capitalize on improved market fundamentals we anticipate in 2025.

“We look forward to receiving the PREPA settlement proceeds and plan to use a portion of the $188.4 million to pay off our term credit facility, which had a balance of approximately $49.3 million as of June 30, 2024. The remaining amount of approximately $139.1 million will be cash on our balance sheet to be used to invest back into our business and for general corporate purposes,” concluded Straehla.

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, 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):
