Key Details

• Transaction date: February 18, 2026 (Form 4 filed Feb 20, 2026).
• Primary conversion: 8,591 shares @ $314.12 = $2,698,605 (reported as conversion/exercise of derivative).

• Notable footnotes: These shares resulted from PSUs granted Mar 1, 2023 under the 2023 LTI Plan (issued at 100% of target and vested after the three‑year performance period). Phantom shares represent rights to receive stock or cash per plan terms.
• Filing timeliness: Form 4 was filed two days after the Feb 18 transactions (not indicated as late).

Context

• This was compensation-related (vesting/conversion of performance awards), not an open-market buy or a voluntary sale; shares were withheld to satisfy tax obligations and some were deferred into phantom stock. Such transactions are routine for executive compensation and do not necessarily signal a change in insider sentiment.
