What Happened

Key Details

  • Transaction date: 2026-03-16; Filing date: 2026-03-18 (timely Form 4 filing).
  • Price: $207.93 per share; Total value: ~$109,163.
  • Transaction code: F — shares withheld to cover tax liabilities on vested RSUs (see footnote F1).
  • Shares owned after the transaction: not specified in the provided filing excerpt.
  • Relevant footnote: F1 — "Shares withheld to cover applicable tax obligations relating to the vesting of restricted stock units."

Context

  • This was a tax-withholding disposition tied to RSU vesting, commonly done by companies to satisfy withholding tax obligations; it does not necessarily indicate the insider is selling shares for cash or signaling a view on the stock.
  • For retail investors, purchase transactions usually carry more informational weight about insider sentiment; withholding disposals are routine administrative actions.
