Remarks
The original Form 4, filed on September 1, 2026, is being amended to restate the Date of Earliest Transaction as September 1, 2026, and clarify the vesting periods of the grant of restricted stock. The original Form 4 erroneously indicated that the Date of Earliest Transaction was December 13, 2024, when, as reported in this amendment, the Date of Earliest Transaction was September 1, 2026.
