F1 The Reporting Person is amending his Form 4 filed December 19, 2025, to add automatic "sell-to-cover" transactions related to the payment of withholding tax obligations pursuant to the Issuer's policy for tax withholdings associated with Restricted Stock Unit vesting events. The sales occurred over a three-day period (December 18, 19 and 22, 2025) and were processed by the Company's stock plan administrator. The Reporting Person did not initiate the sales and had no control over the timing of the sales. The sales were not reported by the Company's stock plan administrator to the Reporting Person until December 22, 2025.
F2 Reported transaction is an automatically-triggered "sell-to-cover" transaction related to the payment of withholding tax obligations pursuant to the Issuer's policy for tax withholdings associated with Restricted Stock Unit vesting events. The Reporting Person did not initiate the sale.
F3 Each Restricted Stock Unit represents a contingent right to receive one share of the Issuer's Common Stock upon vesting.
