Mammoth Energy Services, Inc. Announces

First Quarter 2024 Operational and Financial Results

OKLAHOMA CITY - May 2, 2024 - Mammoth Energy Services, Inc. (“Mammoth” or the “Company”) (NASDAQ: TUSK) today reported financial and operational results for the first quarter ended March 31, 2024.

Financial Overview for the First Quarter 2024:

Total revenue was $43.2 million for the first quarter of 2024 compared to $116.3 million for the same quarter of 2023 and $52.8 million for the fourth quarter of 2023.

Net loss for the first quarter of 2024 was $11.8 million, or $0.25 loss per diluted share, compared to net income of $8.4 million, or $0.17 per diluted share, for the same quarter of 2023 and net loss of $6.0 million, or $0.12 loss per diluted share, for the fourth quarter of 2023.

Adjusted EBITDA (as defined and reconciled below) was $4.5 million for the first quarter of 2024, compared to $30.7 million for the same quarter of 2023 and $10.5 million for the fourth quarter of 2023.

Arty Straehla, Chief Executive Officer of Mammoth commented, “Our results were challenged in the first quarter as activity softness persisted into the first few months of 2024, especially in the natural gas basins in which we operate, which negatively impacted our Well Completion Services division and other oilfield services. This softness resulted primarily from lower energy prices, particularly natural gas, that have caused operators to delay completions activity until later in the year, reducing demand for our services. The first quarter also experienced milder weather than historical trends would have indicated, and this resulted in less storm-related work for our Infrastructure Services business. We continue to prudently assess and manage our costs to more accurately reflect the activity levels of our customers, and as a result, we are proactively lowering our 2024 capex guidance to $9 million, representing a $6 million decrease from our prior guidance.

“As we look ahead to the remainder of 2024, we believe that our first quarter results will serve as the low-water mark for the year. We have improved visibility and expect that we will benefit from increased activity levels later this year. We enter the second quarter with an undrawn revolver and cash on the balance sheet, and we believe Mammoth is well positioned to capitalize on near-term opportunities in the market as well as the increased demand that we anticipate in the second half of the year.

“So far this year, PREPA paid an aggregate of $64 million with respect to our accounts receivable, of which we retained $9.6 million and the remaining $54.4 million was paid to SPCP Group to satisfy, in full, Mammoth’s and Cobra’s obligations under the previously reported financing arrangement with SPCP Group. These payments enhanced our liquidity position and strengthened the Company. However, the amounts paid to date only represent a portion of the outstanding PREPA receivable. Mammoth, through Cobra, is still owed approximately $349 million in principal and associated interest for work that was completed over five years ago.” concluded Straehla.

Well Completion Services

Mammoth’s well completion services division contributed revenue (inclusive of inter-segment revenue) of $8.3 million on 380 stages for the first quarter of 2024, compared to $67.3 million on 2,018 stages for the same quarter

of 2023 and $16.1 million on 669 stages for the fourth quarter of 2023. On average, 0.6 of the Company’s fleets were active for the first quarter of 2024 compared to an average utilization of 3.6 fleets during the same quarter of 2023 and 0.9 fleets during the fourth quarter of 2023.

Infrastructure Services

Mammoth’s infrastructure services division contributed revenue of $25.0 million for the first quarter of 2024 compared to $28.3 million for the same quarter of 2023 and $27.2 million for the fourth quarter of 2023. Average crew count was 75 crews during the first quarter of 2024 compared to 88 crews during the same quarter of 2023 and 78 crews during the fourth quarter of 2024.

Natural Sand Proppant Services

Mammoth’s natural sand proppant services division contributed revenue (inclusive of inter-segment revenue) of $4.3 million for the first quarter of 2024 compared to $12.5 million for the same quarter of 2023 and $4.5 million for the fourth quarter of 2023. In the first quarter of 2024, the Company sold approximately 146,000 tons of sand at an average sales price of $24.38 per ton compared to sales of approximately 391,000 tons of sand at an average sales price of $31.02 per ton during the same quarter of 2023. In the fourth quarter of 2023, sales were approximately 104,000 tons of sand at an average price of $23.62 per ton. Additionally, during the fourth quarter of 2023, the Company recognized shortfall revenue of approximately $2.0 million.

Drilling Services

Mammoth’s drilling services division contributed revenue (inclusive of inter-segment revenue) of $0.5 million for the first quarter of 2024 compared to $1.4 million for the same quarter of 2023 and $0.6 million for the fourth quarter of 2023. The decrease in drilling services revenue is primarily attributable to decreased utilization for our directional drilling business.

Other Services

Mammoth’s other services, including aviation, equipment rentals, remote accommodations and equipment manufacturing, contributed revenue (inclusive of inter-segment revenue) of $6.2 million for the first quarter of 2024 compared to $7.5 million for the same quarter of 2023 and $4.9 million for the fourth quarter of 2023.

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):
