Insights

Corporate Governance Analyst

TL;DR: Officer sold 1,000 shares under a pre-existing 10b5-1 plan adopted 03/20/2025.

The sale of 1,000 shares at $338.08 is documented as a planned transaction under a Rule 10b5-1 trading plan, which typically means the timing and price were set by a pre-authorized instruction rather than a discretionary decision by the officer on the transaction date. The filing reports residual beneficial ownership of 65,121.526 shares, showing continued exposure to the issuer's equity.

Reliance on a 10b5-1 plan reduces regulatory uncertainty for the officer but investors may monitor further scheduled trades or updates to the plan. Watch for any future Form 4s that change the plan terms or disclose additional scheduled dispositions within the next 12 months.
