OKLAHOMA CITY, May 11, 2026 /PRNewswire/ -- Mammoth Energy Services, Inc. (NASDAQ: TUSK) ("Mammoth" or the "Company") today reported financial and operational results for the first quarter ended March 31, 2026.

Mark Layton, Chief Financial Officer of Mammoth commented, "The first quarter is a meaningful step forward for Mammoth and reflects the work we've been doing over the past several quarters to reposition the business. We've simplified the portfolio, allocated capital towards high returns businesses, and taken meaningful cost out of the structure — and we're starting to see that come through in the results.

Aviation continues to perform well and is providing a more stable earnings base, and across the rest of the platform we're seeing clear signs of improvement as the operational changes we made coming out of the fourth quarter begin to take hold.

Our balance sheet remains a real point of strength. We ended the quarter debt-free with approximately $125 million of cash, cash equivalents and marketable securities, which gives us flexibility both to invest in the business and return capital to shareholders. During the quarter, we began executing on our share repurchase program for the first time since it was authorized, and we expect to remain opportunistic going forward.

Based on the progress we're seeing, we are raising our 2026 outlook, including now expecting to reach full-year Adjusted EBITDA positive in 2026. There's still work to do, but the business is moving in the right direction and we're focused on continuing to execute."

RECONCILIATION OF NON-GAAP FINANCIAL MEASURES

Adjusted EBITDA from Continuing Operations

Adjusted EBITDA from continuing operations is a supplemental non-GAAP financial measure that is used by management and external users of our financial statements, such as industry analysts, investors, lenders and rating agencies. We define Adjusted EBITDA from continuing operations as net income (loss) from continuing operations before depreciation, depletion, amortization and accretion, gains on disposal of assets, net, stock based compensation, interest income, net, inclusive of related parties, unrealized gain on marketable securities, net, other expense, net (which is comprised of interest on trade accounts receivable and certain legal expenses) and provision for income taxes, further adjusted to add back interest on trade accounts receivable. We exclude the items listed above from net income (loss) from continuing operations in arriving at Adjusted EBITDA from continuing operations because these amounts can vary substantially from company to company within our industries depending upon accounting methods and book values of assets, capital structures and the method by which the assets were acquired. Adjusted EBITDA from continuing operations should not be considered as an alternative to, or more meaningful than, net income (loss) from continuing operations or cash flows from operating activities as determined in accordance with GAAP or as an indicator of our operating performance or liquidity. Certain items excluded from Adjusted EBITDA from continuing operations 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 historical costs of depreciable assets, none of which are components of Adjusted EBITDA from continuing operations. Our computations of Adjusted EBITDA from continuing operations may not be comparable to other similarly titled measures of other companies. We believe that Adjusted EBITDA from continuing operations is a widely followed measure of operating performance and may also be used by investors to measure our ability to meet debt service requirements.

The following tables provide a reconciliation of Adjusted EBITDA from continuing operations to net income (loss) from continuing operations, the most directly comparable GAAP financial measure for the specified periods (in thousands):
