Remarks:

This Form 4/A amends the Form 4 filed on February 4, 2026 to correct the transaction code reported for the disposition of shares withheld to satisfy tax withholding obligations in connection with the vesting of restricted stock units. The original filing incorrectly reported the transaction using code "S." The transaction is hereby corrected to reflect code "F," as the shares were withheld by the Issuer to satisfy tax withholding obligations and are exempt pursuant to Rule 16b-3(e) under the Securities Exchange Act of 1934. The Form 4 is otherwise unchanged.
