Share-Based Payment Arrangement [Abstract] |
Equity Based Compensation | Equity Based Compensation During June 2026, all outstanding Specified Member and Non-Employee Member awards were settled through the transfer of shares of Mammoth common stock by the majority equity holder of MEH Sub. As a result, all rights under the awards were cancelled and extinguished. The Company recognized equity based compensation expense of approximately $0.5 million during the three and six months ended June 30, 2026, with a corresponding capital contribution recorded in equity. No unrecognized compensation cost remained as of June 30, 2026. Stock Based Compensation On April 29, 2024, the board of directors of Mammoth adopted the Mammoth Energy Services, Inc. 2024 Equity Incentive Plan (the “2024 Plan”). The 2024 Plan authorizes the Company’s board of directors or the compensation committee of the Company’s board of directors to grant restricted stock, restricted stock units, stock appreciation rights, stock options and performance awards. There are a maximum of 1.9 million shares of common stock reserved for issuance under the 2024 Plan, of which 1.9 million shares of common stock remain available for future grants under the 2024 Plan at June 30, 2026. Restricted Stock Units The fair value of restricted stock unit awards was determined based on the fair market value of the Company’s common stock on the date of the grant. This value is amortized over the vesting period. At June 30, 2026, there was no unrecognized compensation cost. No shares vested during the three and six months ended June 30, 2026. The total fair value of shares vested was $0.5 million and $0.6 million during the three and six months ended June 30, 2025, respectively. Included in “selling, general and administrative” on the unaudited condensed consolidated statements of operations and comprehensive income (loss) is stock based compensation expense of $0.2 million and $0.4 million for the three and six months ended June 30, 2025, respectively.
