The withholding was recorded as a disposition valued at $8,393,477 (28,184 shares × $297.81) on March 10, 2026. This is a tax-withholding event (transaction code F), not an open-market sale.

Key Details

• Transaction date and price: March 10, 2026 — 28,184 shares at $297.81 per share (total $8,393,477).
• Transaction type: F — shares withheld by the issuer to pay taxes upon vesting of restricted stock (routine tax withholding).
• Shares owned after transaction: Not specified in the filing.
• Filing: Report filed March 12, 2026 for the March 10 transaction; appears to be timely (filed within the typical two-business-day window).
• Notable footnotes:

  • F2–F4: Some shares are held through affiliated entities and a family trust; the reporting person disclaims beneficial ownership of certain holdings except to the extent of any pecuniary interest.

Context

• Tax-withholding dispositions on vested restricted stock are routine and do not necessarily indicate the insider is selling additional shares or expressing a market view. This was a cashless action by the company to satisfy tax obligations rather than a discretionary sale.
