Key Details

  • Transaction date: 2026-05-22
  • Transaction type/code: F — payment of tax liability (shares withheld) in connection with vesting of restricted stock
  • Shares withheld/disposed: 1,898 at $133.00 each = $252,434
  • Footnote F1: confirms these shares were withheld to satisfy the reporting person’s tax obligations on vesting. The filing includes additional footnotes describing various trust holdings (F2–F8) for the reporting person and family.
  • Shares owned after transaction: not specified in the provided excerpt of the filing.
  • Filing date: 2026-05-27 — this appears to be after the typical two-business-day Form 4 filing window for a 2026-05-22 transaction, so the filing may be late.

Context
This was a tax-withholding disposal related to restricted stock vesting (i.e., shares withheld to cover taxes), not an open-market sale. Such withholdings are routine and do not necessarily indicate the insider’s view on the company’s prospects.
