PR Newswire

Fri, Mar 7, 2025, 6:00 AM 16 min read

Phil Lancaster, Chief Executive Officer of Mammoth commented, "There were signs of improvement in our results for the fourth quarter. Despite typical seasonality and budget exhaustion, we experienced increased utilization which helped drive sequential improvement. Although we expect 2025 activity to be relatively steady, we have line of sight for potential upside performance compared to 2024 driven by incremental natural gas-related demand, which may further contribute to improved financial results. While these tailwinds may not materialize until later this year, we are seeing elevated activity from our customers that will lead to additional utilization improvements in the first quarter.

"Looking ahead, we expect to continue building upon our recent positive momentum in 2025. Our focus will be on operational execution, efficiency and unlocking value within our business. We have a debt-free balance sheet with approximately $86 million in cash today (inclusive of $21 million restricted cash) that we plan to strategically utilize to make accretive investments for future growth in Mammoth. We believe there are numerous opportunities to unlock value for our shareholders, and we look forward to sharing these developments with you in the coming quarters."

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 (loss) income before depreciation, depletion, amortization and accretion expense, gains on disposal of assets, net, impairment of goodwill, stock based compensation, interest expense and financing charges, 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 (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 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. Mammoth defines adjusted net loss as net loss before impairment of goodwill. Mammoth defines adjusted basic and diluted loss per share as 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 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.
