Key Details

• Transaction date: February 17, 2026 (reported Feb 19, 2026) — filing appears timely (within the two-business-day Form 4 window).
• Transaction type: Sale (code S); total shares sold = 4,849; total proceeds ≈ $600,327.
• Price ranges (per footnotes): sales executed across prices from $122.10 to $126.34; several entries show weighted-average prices with full breakdowns available on request (Footnotes F2–F5).
• Reason: Footnote F1 states these were automatic "sell-to-cover" sales to satisfy tax withholding on vested restricted stock units (RSUs), not discretionary trades by the reporting person.
• Shares owned after transaction: not specified in the summary provided.

Context
These were tax-withholding (sell-to-cover) sales tied to RSU vesting, which are routine and generally do not signal insider sentiment about the company. The Form 4 footnotes commit to provide transaction-level price details on request if needed.
