Context

• These sales were routine disposition transactions under a pre‑arranged 10b5‑1 plan to satisfy tax obligations related to RSUs; such planned sales are common and do not by themselves indicate a change in company outlook.
• Purchases generally carry more weight for signaling insider conviction; this report documents routine insider selling tied to equity compensation.
