Insights

Insider Transactions Analyst

TL;DR: Director exercised 1,502 options and sold the resulting shares under a 10b5-1 plan on 10/07/2025.

The director exercised vested stock options at an exercise price of $87.87 to acquire 1,502 shares and then sold those shares in two tranches at weighted average prices of $89.24 and $90.01. The sales were carried out under a written Rule 10b5-1 plan adopted on 03/07/2025, which provides an affirmative defense against insider trading claims if properly structured.

The main dependency is the documented 10b5-1 plan timing and execution; the filing includes statements that the sales were pursuant to that plan. Investors may note the near-term liquidity event reduced direct holdings to 22,803 shares; this is a routine insider monetization rather than a change in control or compensation structure.
