Explanation of Responses:

Id	Content
F1	On July 15, 2025, the Company granted Mr. Stinchcomb 2,400,000 restricted stock units (RSUs) with tandem dividend equivalent rights under the 2020 Omnibus Incentive Plan. Each RSU represents the right to receive one share of common stock. The RSUs granted are performance-based, subject to the Company achieving certain stock price or financial performance goals. All vesting is subject to continued employment on the applicable vesting date and any RSUs not earned during the term of Mr. Stinchcomb's employment agreement ("Agreement") will be cancelled. The dividend equivalents rights entitle Mr. Stinchcomb to payout of dividends accrued on each unvested RSU to the extent such RSUs vest and are distributed under the Agreement.
F2	On March 10, 2026, the Board determined that the Company met the second performance condition of the award by achieving 40% revenue growth and 35% adjusted free cash flow growth for the full year 2025 compared to 2024, and thereby triggering the vesting of the second tranche of the Award, or 600,000 RSUs.
F3	Represents the withholding of shares of the Company's common stock for tax purposes in connection with the vesting of restricted stock units previously granted
