Context
The sale was executed under a pre-arranged 10b5-1 plan, which is a common mechanism for insiders to sell shares according to a set schedule and can limit the implication of opportunistic timing. The mention of RSUs describes the nature of some holdings and their vesting through 2029; this does not alter the fact that the reported transaction was a sale. For full holdings, vesting schedules, and plan details, consult the complete Form 4 filing (Accession 0002075704-26-000009).
