Form 144 — notice of proposed sale of securities
Actionable Insight • Neutral

Monitor for the actual sale on Form 4 to confirm execution. The $2.7M sale is modest relative to the $2.2B market cap and follows recent insider selling patterns. No immediate price catalyst — treat as routine portfolio diversification by an officer.
