Mammoth Energy Services, Inc. Announces First Quarter 2021 Operational and Financial Results


OKLAHOMA CITY, April 29, 2021 (GLOBE NEWSWIRE) -- Mammoth Energy Services, Inc. (“Mammoth” or the “Company”) (NASDAQ: TUSK) today reported financial and operational results for the first quarter ended March 31, 2021.

Financial Overview for the First Quarter 2021:

Total revenue was $66.8 million for the three months ended March 31, 2021, down 22% from $85.1 million for the three months ended December 31, 2020 and down 31% from $97.4 million for the three months ended March 31, 2020.

Net loss for the three months ended March 31, 2021 was $12.4 million, or $0.27 per fully diluted share, as compared to a net loss of $11.9 million, or $0.26 per fully diluted share, for the three months ended December 31, 2020 and a net loss of $84.0 million, or $1.85 per fully diluted share, for the three months ended March 31, 2020.

Adjusted EBITDA (as defined and reconciled below) was $6.4 million for the three months ended March 31, 2021, as compared to $7.5 million for the three months ended December 31, 2020 and $13.5 million for the three months ended March 31, 2020.

Arty Straehla, Chief Executive Officer of Mammoth commented, “The first quarter of 2021 came in as expected as restoration work on the Gulf Coast came to an end and our infrastructure work moderated slightly. Bidding opportunities for both traditional transmission and distribution work as well as renewable work has increased significantly over the past several months. We expect this increase in bidding opportunities to continue to increase in the coming years as the new administration advances its infrastructure bill to rebuild a broad array of the nation's infrastructure assets. The roughly $2 trillion plan includes several areas in which our teams have expertise, including modernization of the electric grid and a shift to renewables.”

Explanatory Note Regarding Financial Information

The financial information contained in this release should be read in conjunction with the financial information contained in Mammoth’s Annual Reports filed on Form 10-K with the Securities and Exchange Commission (“SEC”), Quarterly Reports on Form 10-Q, Current Reports on Form 8-K and other filings with the SEC.

The Company's Chief Executive Officer and Chief Financial Officer comprise the Company's Chief Operating Decision Maker function (“CODM”). Segment information is prepared on the same basis that the CODM manages the segments, evaluates the segment financial statements and makes key operating and resource utilization decisions. Segment evaluation is determined on a quantitative basis based on a function of operating income (loss) less impairment expense as well as a qualitative basis, such as nature of the product and service offerings and types of customers.

As of March 31, 2021, the Company’s four reportable segments include infrastructure services (“Infrastructure”), well completion services (“Well Completion”), natural sand proppant services (“Sand”) and drilling services (“Drilling”). Prior to the fourth quarter of 2020, the Company included Barracuda Logistics LLC (“Barracuda”) in its Well Completion segment, Cobra Aviation Services LLC (“Cobra Aviation”), Air Rescue Systems Corporation (“ARS”) and Leopard Aviation LLC (“Leopard”) in its Infrastructure segment and Mako Acquisitions LLC (“Mako”) in its Drilling segment. Based on its assessment of FASB ASC 280, Segment Reporting, guidance at December 31, 2020, the Company changed its presentation in 2020 to move Barracuda to the Sand segment and Cobra Aviation, ARS, Leopard and Mako to the reconciling column titled “All Other”. Additionally, Mammoth changed the name of its pressure pumping segment to the well completion segment during the fourth quarter of 2020. The results for the three months ended March 31, 2020 have been retroactively adjusted to reflect these changes.

MAMMOTH ENERGY SERVICES, INC.
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, impairment of goodwill, impairment of other long-lived assets, 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 interest on trade accounts receivable) 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 Loss and Adjusted Loss per Share

Adjusted net loss and adjusted basic and diluted loss 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 and adjusted loss per share should not be considered in isolation or as a substitute for net loss and 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 loss and adjusted loss per share to the GAAP financial measures of net loss and loss per share for the periods specified.
