On February 19, 2026, the reporting person filed a Form 4 (the "Original Form 4") which inadvertently reported in the second row of Table I an incorrect amount of shares of common stock withheld to satisfy the reporting person's tax liability due to a clerical error. The corrected amount of securities withheld to satisfy the reporting person's tax liability was 2,960 shares. | Due to immaterial clerical rounding errors, the reporting person's Original Form 4 inadvertently reported an incorrect total amount of securities directly beneficially owned by the reporting person and mistakenly indicated an incorrect amount of unvested restricted stock units owned. The corrected amount of securities beneficially owned by the reporting person is 266,975, of which 44,640 shares represent unvested restricted stock units.
