F2 · balance_after: On February 1, 2024, the reporting person filed a Form 4 which inadvertently reported that, following his exercise of an option and sale of the underlying stock, he no longer owned any stock options exercisable at $28.99. In fact, as reported in this amendment, the reporting person still owned 102,766 options following his exercise. The reporting person subsequently exercised his remaining 102,766 stock options as reported in a Form 4 amendment filed on February 23, 2024 and a Form 4 filed on February 28, 2024 but incorrectly reported remaining balances of such stock options following this original error. Therefore, this amendment also effectively corrects the subsequent incorrect reporting in his subsequent Form 4s of the stock options owned following his subsequent stock option exercises.
