Key Details

Transaction date: March 16, 2026; filing date: March 18, 2026 (Form 4 filed timely).
Price per share: $297.80.
Shares disposed: 36, 40, and 273 (total 349 shares); total proceeds ≈ $103,932.
Shares owned after transaction: not specified in the provided filing summary.
Footnotes: Dispositions represent tax withholding on vested deferred stock awards granted March 14, 2024 and March 14, 2025, and withholding for RSUs purchased under the issuer’s Management Stock Purchase Plan on March 15, 2023. These withholdings are mandatory under the grant/MSPP terms and are coded as F (tax withholding) on Form 4.
Transaction code meaning: F indicates shares were withheld/disposed to cover tax withholding — not a discretionary open-market sale.

Context

Withholding or sell-to-cover of shares on vesting is a common administrative action and does not necessarily indicate the insider’s view on the company’s prospects. For retail investors, purchases by insiders tend to be more informative than mandatory tax-withhold disposals.
