Explanation of Responses:

Id Content
F1 This Form 4 amendment is being filed to correct the number of stock appreciation rights awarded to the Reporting Person on February 13, 2024. The original Form 4 filed on February 16, 2024 inadvertently reported the number of stock appreciation rights awarded as 475,831 due to an administrative error.
F2 The Stock Appreciation Right will vest and become exercisable in equal annual installments (rounding down to the nearest whole share, except for the last installment) on the first, second, and third anniversaries of February 13, 2024, subject to the Reporting Person remaining an employee of the Issuer through and including each applicable vesting date.
