Context
A 10b5‑1 selling plan indicates these sales were pre‑arranged trades (often used to avoid questions about timing), not necessarily a real‑time signal about the director’s view. The RSU award represents a contingent right to receive shares in the future if vesting conditions are met; it is not an immediate cash purchase. Sales are informational but less indicative of positive sentiment than purchases; no options were exercised and no gifts were reported in this filing.
