Explanation of Responses:

( 1 )The award is subject to time-based vesting restrictions. The restrictions will lapse in equal parts on February 3, 2026 and February 3, 2027. ( 2 )Each Performance Share Unit ("PSU") represents the contingent right to receive one share of the Issuer's common stock based on certain vesting conditions. ( 3 )The number of PSUs that will vest and the number of shares of Issuer's common stock that will be awarded, if any, is contingent on the Issuer's cumulative Adjusted EBITDA for the Arcadia Products segment as compared to cumulative target Adjusted EBITDA achieved over the two year period from 2025 through 2026, with potential to earn a number of shares of common stock between 0% and 200% of the number of target PSUs awarded. This PSU award will cliff vest, if at all, on February 3, 2027, based on the performance period ending December 31, 2026.

Remarks: The original Form 4, filed on February 27, 2025, is being amended by this Form 4 amendment solely to correct an administrative error on the part of the Issuer, which misreported the vesting dates now correctly reported in Notes 1 and 3 above.

Reminder: Report on a separate line for each class of securities beneficially owned directly or indirectly.
