Actionable Insight • Neutral

The CFO's sale is a routine cashless exercise (strike $8.90 vs. market $66.35) and likely pre-planned. Director buying provides a modest counter-signal. Monitor next 8-K or earnings for any fundamental change — the selling alone does not warrant action at 0.13% of market cap.

Executive Summary

The CFO's sale is a cashless exercise (option strike $8.90) and likely routine, but the $10.3M total insider selling over a week is notable at 0.13% of market cap.
