Explanation of Responses:
1. These shares were sold by the Reporting Person to cover tax withholding obligations in connection with the vesting of restricted stock units ("RSUs").
2. Represents a performance-based stock option previously granted to the Reporting Person by the Issuer on April 23, 2024 for an aggregate of 54,472 post-split shares (or 140,000 pre-split shares) of Common Stock, which is subject to annual performance-based vesting conditions for each of the fiscal years ending December 31, 2024, 2025, 2026, and 2027. The performance metrics for the 2024 fiscal year were not satisfied, resulting in the automatic cancellation of that portion of the award. On March 10, 2026, the Board of Directors determined that the performance metrics were partially satisfied for the 2025 fiscal year and approved the vesting of the option as to 3,500 post-split shares.
3. The stock option is fully vested as of March 15, 2026 and is currently exercisable.
