Mammoth Energy Services, Inc. Announces Strong
Second Quarter 2022 Operational and Financial Results

Significant Increases in Q2 Revenue, Net Income and Adjusted EBITDA

OKLAHOMA CITY - July 28, 2022 - Mammoth Energy Services, Inc. (“Mammoth” or the “Company”) (NASDAQ: TUSK) today reported strong financial and operational results for the second quarter ended June 30, 2022.

Financial Overview for the Second Quarter 2022:

Total revenue was $89.7 million for the second quarter of 2022, as compared to $47.4 million for the same quarter last year and $62.3 million for the first quarter of 2022.

Net income for the second quarter of 2022 was $1.7 million, or $0.04 per share, as compared to a net loss of $34.8 million, or a $0.75 loss per share, for the same quarter last year, and a net loss of $14.8 million, or a $0.32 loss per share, for the first quarter of 2022.

Adjusted EBITDA (as defined and reconciled below) was $23.0 million for the second quarter of 2022, as compared to ($3.3) million for the same quarter last year and $9.3 million for the first quarter of 2022.

Arty Straehla, Chief Executive Officer of Mammoth commented, “Our significant second quarter growth in revenue, net income and Adjusted EBITDA resulted from substantial gains in Infrastructure Services, Well Completion Services and our Sand business. In our Infrastructure Services division, we have continued to add crews since the first quarter to just over 100 crews currently, and we expect to add additional crews in the coming weeks in preparation for the seasonal storm restoration services anticipated in the third and fourth quarters. Our Well Completion Services division posted the strongest quarter we've seen since mid-2019 resulting from the robust macro demand that the pressure pumping industry is experiencing. We currently have four pressure pumping spreads operating, which have full schedules through the end of the year, and we expect to add a fifth spread sometime in the fourth quarter. Our Sand business is also experiencing strong demand, as well as increased pricing, which we believe will continue to improve into the back half of the year and into 2023. I am proud of our team’s continued commitment and hard work to push through the challenges we have faced over the last few years and am confident that we are well equipped to build on the improvements we have made this quarter.”

On average, 3.5 of the Company’s fleets were active for the second quarter of 2022, compared to an average utilization of 0.9 fleets during the same


quarter last year and 1.6 fleets during the first quarter of 2022. As of July 26, 2022, Mammoth was operating four of its six pressure pumping fleets and currently expects to activate a fifth fleet in the fourth quarter. Looking to 2023, the Company plans to activate its sixth fleet in the first quarter of 2023, and has plans to acquire or build a new Tier 4, dual-fuel fleet for a total of seven fleets by year-end 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 income (loss) before depreciation, depletion, amortization and accretion expense, public offering costs, stock based compensation, interest expense, net, other (income) expense, net (which is comprised of the (gain) or loss on disposal of long-lived assets, 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):
