Mammoth Energy Services, Inc. Announces
Fourth Quarter and Full Year 2022 Operational and Financial Results
Q4 Revenue Up 80% and Full Year Revenue Up 58%


OKLAHOMA CITY - February 23, 2023 - Mammoth Energy Services, Inc. (“Mammoth” or the “Company”) (NASDAQ: TUSK) today reported financial and operational results for the fourth quarter and full year ended December 31, 2022.

Financial Overview for the Fourth Quarter and Full Year 2022:

Fourth quarter 2022 total revenue was $102.9 million, an increase of 80% compared to $57.2 million for the same quarter of 2021. Total revenue for the full year of 2022 was $362.1 million, an increase of 58% compared to $229.0 million in 2021.

Net income for the fourth quarter of 2022 was $4.8 million, or $0.10 per share, compared to a net loss of $13.3 million, or a $0.28 loss per share, for the same quarter of 2021. Net loss for the full year of 2022 was $0.6 million, or $0.01 per fully diluted share, compared to net loss of $101.4 million, or $2.18 per fully diluted share for 2021.

Adjusted EBITDA (as defined and reconciled below) was $24.1 million for the fourth quarter of 2022, an increase of 40% compared to $17.2 million for the same quarter of 2021. Adjusted EBITDA increased to $86.1 million for the the full year of 2022 compared to ($11.6) million for 2021. During the fourth quarter of 2022, Mammoth recognized bad debt expense of $3.5 million due to a previously disclosed legal settlement. Excluding this expense, adjusted EBITDA would have been $27.6 million for the fourth quarter of 2022 and $89.6 million for the full year 2022.

Arty Straehla, Chief Executive Officer of Mammoth commented, “We are pleased to report significant revenue and Adjusted EBITDA growth in the fourth quarter and for the full year. This growth was driven by strong market demand for our services and enhanced execution by our teams. Despite adverse weather during the quarter and continued supply chain constraints that impacted productivity, I am proud of the hard work and perseverance displayed by our talented teams throughout our organization. Our Well Completion Services division continues to improve performance, generating strong growth as the macro demand in the pressure pumping industry remains robust. We exited 2022 with four of our six pressure pumping spreads operating, and we added a fifth spread into operations in January of 2023. In addition, we have plans to upgrade our sixth spread to Tier 4, dual fuel and put it into operation in the second half of 2023 and upgrade two existing spreads to Tier 2, dual fuel, subject to both market conditions and supply chain constraints. This would give us a total of four dual fuel fleets. In our Infrastructure Services division, operational improvements, team performance and higher utilization of crews and equipment continue to drive enhanced results. There is a healthy bidding and pricing environment for infrastructure projects throughout our footprint supported by the historic federal investment in our Nation’s infrastructure through the Infrastructure Investment and Jobs Act. Our sand business also continues to maintain strong demand and we are pleased with our team’s performance. As we reported last November, we entered into two strategic sand supply agreements at attractive pricing that are providing a solid foundation for predictable cash flow in our natural sand proppant division. We believe all of our business segments are performing well in high demand environments despite the continued daily challenges presented by supply chain constraints, which we expect to persist through at least the first half of 2023, inflation and higher labor costs. We are bullish on the future of Mammoth and intend to


continue to focus on improving operational efficiencies across our business segments and driving financial performance to enhance value for our shareholders.”

Commenting further, Straehla said, “As we continue to vigorously pursue payment from the Puerto Rico Electric Power Authority (“PREPA”), last month we reported that two important Determination Memorandums from the Federal Emergency Management Agency (“FEMA”) released late last year affirmed the work we completed on the island and that the majority of the costs were eligible for reimbursement. In a January Joint Status Report filed in PREPA’s bankruptcy case, PREPA indicated that subject to approximately $21.5 million in offsets asserted by PREPA, approximately $99.2 million in FEMA funding would be available to PREPA for our outstanding invoices. Both the November and December 2022 Determination Memorandums can be found on our website. In addition, we have sought and obtained bipartisan help from Senate and Congressional members in pursuit of collecting the over $379 million outstanding receivable from PREPA as the Company continues to pursue multiple avenues to collect the money owed from PREPA.”

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 income (loss) before depreciation, depletion, amortization and accretion expense, gains on disposal of assets, net, impairment of goodwill, impairment of other long-lived assets, public offering costs, 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):

Adjusted Net Income (Loss) and Adjusted Earnings (Loss) per Share

Adjusted net income (loss) and adjusted basic and diluted earnings (loss) per share are supplemental non-GAAP financial measures that are used by management to evaluate the Company’s operating and financial performance. Mammoth defines adjusted net income (loss) as net income (loss) before impairment of goodwill and impairment of other long-lived assets. Mammoth defines adjusted basic and diluted earnings (loss) per share as earnings (loss) per share before the effects of impairment of goodwill and impairment of other long-lived assets. Management believes these measures provide meaningful information about the Company’s performance by excluding certain non-cash charges, such as impairment of goodwill and impairment of other long-lived assets, that may not be indicative of the Company’s ongoing operating results. Adjusted net income (loss) and adjusted earnings (loss) per share should not be considered in isolation or as a substitute for net income (loss) and earnings (loss) per share prepared in accordance with GAAP and may not be comparable to other similarly titled measures of other companies. The following tables provide a reconciliation of adjusted net income (loss) and adjusted earnings (loss) per share to the GAAP financial measures of net income (loss) and earnings (loss) per share for the periods specified.
