Key Details

• Transaction date: 2026-03-31; price per share: $77.95; total value: $3,450,769.
• Transaction code: F — payment of exercise price or tax withholding (shares surrendered/withheld).
• Filing date: Form 4 filed 2026-04-02; no late-filing flag indicated in the report.
• Shares owned after transaction: Not stated in the provided filing excerpt — check the full Form 4 for updated holdings.
• This was not an open‑market sale (shares were withheld to cover taxes), so it’s a routine disposition tied to option exercise/vesting.

Context

• Withholding shares to cover taxes (or exercise costs) is common after option exercises and is generally considered administrative rather than a directional bet on the stock. It does not necessarily signal insider sentiment; look for open‑market purchases or multiple transactions for clearer signals.
