- Withheld share sale price: $47.94 per share; withheld-share proceeds ≈ $331,026.
- Net increase in shares held by Rogers from this event: +9,207 shares.
- Footnotes: Withheld shares satisfy the reporting person’s tax withholding obligations; the issuer pays the taxes on the reporting person’s behalf (see F1, F2). RSUs were from 2024 and 2025 grant dates and vest in three equal annual installments (see F3, F4).
- Filing timing: appears timely (filed within the two-business-day Form 4 window).
Context
- This was a vesting/conversion of RSUs with shares withheld for tax obligations (a common cashless-withholding method), not an open-market sale or purchase that signals trading intent.
- For retail investors, award vesting and employer tax withholding are routine and reflect compensation mechanics rather than a direct insider market view.
