Mammoth Energy Services, Inc. Announces
Second Quarter 2020 Operational and Financial Results


OKLAHOMA CITY, OKLAHOMA, July 30, 2020 - Mammoth Energy Services, Inc. (“Mammoth” or the “Company”) (NASDAQ: TUSK) today reported financial and operational results for the second quarter ended June 30, 2020.

Financial Highlights for the Second Quarter 2020:

Total revenue was $60.1 million for the three months ended June 30, 2020, down 38% from $97.4 million for the three months ended March 31, 2020 and down 67% from $181.8 million for the three months ended June 30, 2019.

Net loss for the three months ended June 30, 2020 was $15.2 million, or $0.33 per fully diluted share, as compared to net loss of $84.0 million, or $1.85 per fully diluted share, for the three months ended March 31, 2020 and net loss of $10.9 million, or $0.24 per fully diluted share, for the three months ended June 30, 2019.

Adjusted EBITDA (as defined and reconciled below) was $6.9 million for the three months ended June 30, 2020, as compared to $13.5 million for the three months ended March 31, 2020 and $8.6 million for the three months ended June 30, 2019.

Arty Straehla, Mammoth's Chief Executive Officer, stated, “The second quarter of 2020 saw the release of a very important report prepared by the Rand Corporation for the U.S. Department of Homeland Security. The report was prepared at the request of the Federal Emergency Management Agency to assess the reasonableness of our subsidiary Cobra’s Master Service Agreement with the Puerto Rico Electric Power Authority (“PREPA”) for repairs to PREPA's electrical grid following Hurricane Maria. This detailed 77-page report found, among other things, that the selection of Cobra was reasonable, that PREPA adhered to procurement statutes and policies in awarding the contract to Cobra and that Cobra’s rates were reasonable. We believe these are important data points as we continue to pursue payment from PREPA for the quality work performed by our team.”

“In looking at our financial results, it is clear that our infrastructure services segment has turned a corner with gross margin increasing to 17% during the second quarter of 2020 and Adjusted EBITDA in this segment growing nearly 50% quarter-over-quarter for the last two consecutive quarters. The initiatives taken by our infrastructure management team have laid a solid foundation for growth.”

“While the oilfield portion of our service offerings have experienced significant challenges as of late given the current industry and macroeconomic environment, we continue to maintain our oilfield equipment and plan to be ready to ramp up our service lines once demand returns,” concluded Straehla.

Infrastructure Services

Mammoth's infrastructure services division contributed revenue of $30.6 million for the three months ended June 30, 2020, an increase of 19% from $25.7 million for the three months ended March 31, 2020 and a decrease of 27% from $41.8 million for the three months ended June 30, 2019.

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, impairment of goodwill, impairment of other long-lived assets, acquisition related 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) 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):

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

Adjusted net (loss) income and adjusted basic and diluted (loss) earnings per share are supplemental non-GAAP financial measures that are used by management to evaluate the Company's operating and financial performance. 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 (loss) income and adjusted (loss) earnings per share should not be considered in isolation or as a substitute for net (loss) income and (loss) earnings 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 (loss) income and adjusted (loss) earnings per share to the GAAP financial measures of net (loss) income and (loss) earnings per share for the periods specified.
