Context
Sales under a pre‑arranged Rule 10b5‑1 plan are common for insiders and are typically automatic rather than timed to material nonpublic information. The RSU grant is standard executive/director compensation and will only convert to shares upon vesting; these two events (grant and planned sales) should be viewed as separate actions recorded the same day.
