Key Details

  • Transaction dates/prices:
    • Mar 10, 2026: Grant of 14,970 RSUs (value $0 reported for grant entry; see footnotes for vesting schedule).
    • Mar 10, 2026: Converted/exercised 7,978 and 4,027 derivative shares (records show $0 for the derivative disposition entries).
    • Mar 11, 2026: Converted/exercised 4,971 derivative shares.
    • Tax-withholding share disposals (company withheld shares to cover taxes): 3,140 @ $48.60 ($152,604); 1,585 @ $48.60 ($77,031); 1,957 @ $48.56 ($95,032).
  • Total withheld shares: 6,682; total withholding value: ~$324,667.
  • Shares owned after the transactions: Not specified in the provided filing excerpt.
  • Footnotes: F1–F6 explain these are restricted stock units that convert to one share per vested RSU; F2 confirms shares were withheld to satisfy tax obligations; F3–F6 list prior RSU grants (2023–2025) that vest in annual installments and likely supplied vested shares.
  • Filing: Report filed Mar 12, 2026 for transactions through Mar 11, 2026 — appears timely (Form 4s are generally due within two business days).

Context
These entries reflect vesting/conversion of RSUs (derivative conversion, transaction code M) and the routine withholding of shares to cover tax obligations (transaction code F). This is not an open-market sale; withheld shares are a common cashless way to pay taxes when RSUs vest and do not by themselves indicate a change in insider sentiment.
