Key Details

• Transaction date and price: 2026-06-12 — 365 shares @ $276.64 each (total $100,974).
• Filing: Form 4 filed 2026-06-16 (filed within the standard two-business-day reporting window).
• Shares owned after transaction: Not specified in the provided details.
• Footnote: Sale was made pursuant to a Rule 10b5-1 trading plan adopted August 12, 2025 to cover the insider’s estimated tax obligations related to restricted stock unit vesting.

Context
Sales under 10b5-1 plans are often pre-arranged and used for routine needs such as tax withholding on vested awards; they do not necessarily signal a change in the insider’s view of the company. The transaction size (~$101k) is modest and appears tied to tax obligations per the filing footnote.
