Corporate Governance Expert

TL;DR: Transactions are routine equity compensation mechanics: RSU vesting tax withholding and exercised options delivered to reporting person.

The filing documents routine equity plan activity: RSUs granted on three separate dates and vesting schedules are referenced; withheld shares satisfied tax obligations under Rule 16b-3(e). The exercised stock options had a $0.686 exercise price and were fully vested as of 12/31/2024 per the footnotes.
