Insights

Insider Transactions Specialist

Insider sold more shares than exercised under a pre-established 10b5-1 plan.

The Form 4 shows a contemporaneous exercise of 2,000 options at $101.64 and a sale of 3,000 shares at $274.36 on 10/01/2025. Both moves are reported as executed under a Rule 10b5-1 plan adopted 2/19/2025, which documents a predefined trading schedule and can limit questions about opportunistic timing.

This pattern — exercising options and selling a larger parcel — is a common liquidity and tax-management activity for executives. The remaining beneficial ownership of 86,745 shares remains material for tracking insider alignment with shareholders.
