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


OKLAHOMA CITY - April 27, 2023 - Mammoth Energy Services, Inc. (“Mammoth” or the “Company”) (NASDAQ: TUSK) today reported financial and operational results for the first quarter ended March 31, 2023.

Financial Overview for the First Quarter 2023:

Total revenue was $116.3 million for the first quarter of 2023, an increase of 87% compared to $62.3 million for the same quarter of 2022 and an increase of 13% compared to $102.9 million for the fourth quarter of 2022.

Net income for the first quarter of 2023 was $8.4 million, or $0.17 per diluted share, compared to a net loss of $14.8 million, or a $0.32 loss per share, for the same quarter of 2022 and net income of $4.8 million, or $0.10 per share, for the fourth quarter of 2022.

Adjusted EBITDA (as defined and reconciled below) was $30.7 million for the first quarter of 2023, an increase of 230% compared to $9.3 million for the same quarter of 2022 and an increase of 27% compared to $24.1 million for the fourth quarter of 2022.

Arty Straehla, Chief Executive Officer of Mammoth commented, “Our first quarter performance was in line with our expectations, contributing to significant year-over-year growth in revenue, net income and Adjusted EBITDA. Our talented and hard-working teams throughout the organization continue to manage through a challenging economic environment for our customers, especially related to supply chain constraints that persist in many of our business segments. Our Well Completion Services division generated strong growth in the quarter, however, the oil field services markets that we serve are now being negatively impacted by lower commodity prices, in particular natural gas prices, which are restricting utilization of our well completion services and capacity growth. Natural gas prices have been cut nearly in half since the end of 2022, which is resulting in a reduction in completions activity across the industry, particularly in the northeast where we have a concentration of frac fleets. While we remain bullish long-term on natural gas, in the near-term, the lower commodity prices are reducing activity and leading to more calendar white space, which we expect is likely to reduce near-term utilization in our well completion segment as we adjust to market conditions. As we continue to work with our customers to keep as many fleets active as we can, we are also utilizing our extensive experience to manage our assets and the variable costs in this segment as we adjust to market conditions. We now plan to significantly reduce our capital expenditures for the year to approximately $24 million.”

Commenting further, Straehla said, “In our Infrastructure Services division, we experienced strong year-over-year revenue and profitability growth due to operational improvements, team performance and higher utilization of crews and equipment. The bidding and pricing environment for infrastructure services throughout our footprint continue to be robust, with added opportunities expected from the Infrastructure Investment and Jobs Act (IIJA). This business segment, that has grown organically, we believe will be a key growth driver for Mammoth over the long term and I’m pleased with its continual progress. In addition, the sand business also grew in the quarter compared to last year, and we are pleased with our team’s performance. Mammoth has a diverse portfolio of assets and businesses across several dynamic market segments that we believe possess an ability to adapt quickly to evolving market conditions.



Our experienced team remains focused on managing this portfolio efficiently and effectively to create long-term value for all of our stakeholders.”

Well Completion Services
Mammoth’s well completion services division contributed revenue (inclusive of inter-segment revenue) of $67.3 million on 2,018 stages for the first quarter of 2023, compared to $23.9 million on 699 stages for the same quarter of 2022 and $51.4 million on 1,837 stages for the fourth quarter of 2022. On average, 3.6 of the Company’s fleets were active for the first quarter of 2023 compared to an average utilization of 1.6 fleets during the same quarter of 2022 and 3.4 fleets during the fourth quarter of 2022.

Infrastructure Services
Mammoth’s infrastructure services division contributed revenue of $28.3 million for the first quarter of 2023 compared to $23.0 million for the same quarter of 2022 and $29.6 million for the fourth quarter of 2022. Average crew count was 88 crews during the first quarter of 2023 compared to 85 crews during the same quarter of 2022 and 93 crews during the fourth quarter of 2022.

Natural Sand Proppant Services
Mammoth’s natural sand proppant services division contributed revenue (inclusive of inter-segment revenue) of $12.5 million for the first quarter of 2023 compared to $9.2 million for the same quarter of 2022 and $13.8 million for the fourth quarter of 2022. In the first quarter of 2023, the Company sold approximately 391,000 tons of sand at an average sales price of $31.02 per ton compared to sales of approximately 329,000 tons of sand at an average sales price of $21.44 per ton during the same quarter of 2022. In the fourth quarter of 2022, sales were approximately 366,000 tons of sand at an average price of $29.80 per ton.

Drilling Services
Mammoth’s drilling services division contributed revenue (inclusive of inter-segment revenue) of $1.8 million for the first quarter of 2023 compared to $2.9 million for the same quarter of 2022 and $2.4 million for the fourth quarter of 2022. 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 $7.0 million for the first quarter of 2023 compared to $4.7 million for the same quarter of 2022 and $6.4 million for the fourth quarter of 2022. The increase in revenue is primarily due to improved utilization for our equipment rental and remote accommodations businesses.

Selling, General and Administrative Expenses
Selling, general and administrative (“SG&A”) expenses were $8.4 million for the first quarter of 2023 compared to $8.7 million for the same quarter of 2022 and $13.0 million for the fourth quarter of 2022.

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 income (loss) before depreciation, depletion, amortization and accretion expense, 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 income (loss) 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 income (loss) 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 income (loss) on a consolidated basis and for each of the Company’s segments (in thousands):
