Key Details

• Transaction date and price: 2026-07-14, 328 shares withheld at $72.01/share (total $23,619).
• Transaction code: F (payment of exercise price or tax liability — tax withholding on vested RSUs).
• Footnotes: F1 — shares withheld to satisfy tax withholding upon RSU vesting; this is not a sale by the reporting person. F2 — the amount reported includes shares subject to unvested RSUs.
• Shares owned after transaction: Not specified in the Form 4 filing.
• Filing timeliness: Reported on 2026-07-14 (period of report 2026-07-14), i.e., timely as filed.

Context

• This was a routine tax-withholding transaction related to RSU vesting (a cashless withholding), which reduces the number of shares delivered to the insider to cover taxes and does not necessarily indicate a change in the insider’s view of the company.
• For retail investors, purchases or open-market sales are often more indicative of sentiment; tax withholdings on vesting are standard administrative events.
