The withholding consisted of 16,266 shares (valued at $64.53 each, $1,049,645) and 3,851 shares (valued at $64.53 each, $248,505), for a combined value of about $1,298,150.
- These transactions are reported with code F, meaning shares were surrendered/withheld to cover tax liabilities — not an open-market sale initiated by the insider.
Key Details
- Transaction date: 2026-02-27. Form 4 filed: 2026-03-03 (filed 4 days after the transaction; Form 4s are generally due within 2 business days, so this appears late).
- Prices: $64.53 per share for both withholdings.
- Shares withheld: 16,266 (PSU withholding) + 3,851 (RSU withholding) = 20,117 shares; total value ≈ $1,298,150.
- Footnotes: F1 = shares withheld to pay tax on vested Performance Share Units from the 2023–2025 cycle; F2 = shares withheld to pay tax on vested Restricted Share Units from the 2023–2025 cycle.
- Shares owned after transaction: not specified in the provided filing.
Context
- This is a routine tax-withholding transaction tied to vesting of equity awards (PSUs and RSUs). Such withholdings are common and do not necessarily signal insider sentiment about the company's stock — they simply satisfy payroll/tax obligations.
- These were not open-market sales or option exercises for cash; the company withheld shares (a “sell to cover” type action) to satisfy taxes.
