Explanation of Responses:

( 1 )This Form 3/A is being filed to correct the number of shares of common stock and Performance Restricted Stock Units ("PRSU") reported in Tables I and II, respectively, of the original Form 3 filed on October 3, 2025. Table I inadvertently reported 40,336 shares of common stock beneficially owned by the reporting person instead of the 51,330 shares reported herein. Table II inadvertently omitted 16,491 PRSUs granted to the reporting person on August 26, 2025, reported herein. ( 2 )Each PRSU represents a right to receive one share of issuer common stock, with the total number of units reflecting the number that are eligible to be earned at target-level performance achievement. Upon achievement of the maximum level of the applicable performance criteria, the reporting person may become eligible to earn 200% of the target number of units. ( 3 )The PRSUs were granted on December 23, 2024. The number reported reflects the unvested PRSUs remaining under such grant. The PRSUs will vest only to the extent the specified financial performance criteria are achieved and subject to the reporting person's continued service with the issuer, as follows (i) 50% of the earned award vested on August 31, 2025 (ii) 30% of the earned award will vest on August 31, 2026 and (iii) 20% of the earned award will vest on August 31, 2027. ( 4 )The PRSUs were granted on August 26, 2025. The PRSUs will vest only to the extent the specified financial performance criteria are achieved and subject to the reporting person's continued service with the issuer, as follows: (i) 34% of the earned award will vest on September 10, 2026 (ii) 33% of the earned award will vest on September 10, 2027 and (iii) 33% of the earned award will vest on September 10, 2028.
