Incentive Plans
2024 Omnibus Incentive Plan

The Company has reserved 13.0 million shares of Common Stock for issuance pursuant to the 2024 Omnibus Incentive Plan (the “2024 Incentive Plan”), and the maximum number of units that may be issued pursuant to the vesting of incentive awards under the 2024 Incentive Plan is 13.0 million units, subject to certain adjustments. Each unit represents the right to receive one share of Common Stock. The 2024 Incentive Plan authorizes the awards of several types of equity compensation including stock options, restricted stock units (“RSU”), stock appreciation rights, performance awards (“PRSU”) and other stock-based compensation.
Restricted Stock Units

RSUs outstanding at December 31, 2025 generally vest 33⅓% annually over three years from date of grant and are dependent upon continued employment. Non-employee board of director grants generally vest one year after the date of grant or on the date of the annual stockholders’ meeting following the date of grant, whichever date occurs first. As RSU vest, the units will be settled in shares of common stock based on a one-to-one ratio.
Performance Restricted Stock Units

PRSU outstanding at December 31, 2025 generally vest upon achievement of key non-financial or non-stock dependent performance metrics as detailed in the grant agreement and are also dependent upon continued employment. As PRSU vest, the units will be settled in shares of common stock based on a one-to-one ratio.
USARE LLC Incentive Plan

USARE LLC issued incentive units under the Amended and Restated Incentive Plan dated May 1, 2020 and the Second Amended and Restated Equity Incentive Plan dated August 26, 2022 and amended November 2, 2022 and February 10, 2024 (the “Legacy Incentive Plan”). The incentive units were intended to constitute “profit interests” within the meaning of the U.S. Internal Revenue Service (“IRS”) Revenue Procedures 93-27 and 2001-43 (or the corresponding requirements of any subsequent guidance promulgated by the IRS or other applicable law). The rights and preferences of the incentive units were defined in the respective incentive unit agreements. The Company did not forfeit or grant any new incentive units under the Legacy Incentive Plan as of the closing date of the Merger. In addition, the Legacy Incentive Plan is closed and no new grants will be awarded under this plan.
Fair Value Assumptions
Restricted Stock Unit. The fair value of RSU granted to employees is based on the Company’s common stock price on the date of grant.
Performance Restricted Stock Unit. The fair value of PRSU granted to employees is based on the Company’s common stock price on the date of grant.
Incentive Units. USARE LLC utilized an independent valuation company to estimate the fair value of the underlying equity units into which the incentive units granted under the Legacy Incentive Plan would be converted. During the year ended December 31, 2024, the Company then used this valuation in a Black-Scholes pricing model to determine the fair value of the incentive units granted. The Black-Scholes pricing method is considered to be a Level 3 fair value measurement requiring highly judgmental assumptions including expected volatility. The expected volatility was estimated by taking the average historical price volatility for industry peers, consisting of several public companies in its industry which are either similar in size, stage of life cycle, or financial leverage, over a period equivalent to the expected term of the awards. USARE LLC recognized the associated costs across the vesting period using the straight-line method. All outstanding and unvested incentive units under the Legacy Incentive Plan vested upon the closing of the Merger and unrecognized equity-based compensation expense of incentive units vested on that date of $0.2 million was recognized in the Consolidated Statements of Operations and Comprehensive Loss for the year ended December 31, 2025.
The assumptions used in determining the fair value of incentive units are as follows. The Company did not grant any incentive units in fiscal year 2025.

Vesting Period of Incentive Units. USARE LLC utilized different vesting periods, generally ranging from 1 year to 5 years, depending on the specifics of the grant. If there is a change in control, unless otherwise expressly provided in the participant’s award agreement, the units will become 100% vested and any restrictions and limitations applicable to the participant’s incentive units shall lapse and such incentive units shall become fully transferable.

If any of the units are forfeited prior to vesting, USARE LLC reversed the associated compensation cost during the period in which the forfeiture occurs.

Conversion of Incentive Units. Upon Closing of the Merger, all outstanding incentive units were considered fully vested and converted into approximately 4.55 million shares of Common Stock using the treasury method of accounting on a cashless exercise basis and an exchange conversion ratio of approximately 0.204 shares of Common Stock for a share of common stock of USARE LLC.
