Explanation of responses

Remarks

The original Form 4, filed on July 20, 2026, is being amended to correct the ownership total in Table I, Column 5 to reflect 12,211 shares beneficially owned by the Reporting Person following the reported transaction and correct the vesting periods of the grant of restricted stock. The original Form 4 understated the ownership total in Table I, Column 5 by 1,055 shares due to an administrative error. In addition, the original Form 4 erroneously indicated that the shares of restricted stock would vest in equal installments on each of the first three anniversaries of July 16, 2026, when, as reported in this amendment, the shares of restricted stock vest on each of the first three anniversaries of December 13, 2024, such that 100% of the shares of restricted stock granted shall be fully vested on December 13, 2027.
