Context RSUs are a contractual right to receive shares upon vesting; they do not represent immediate cash proceeds or open‑market buying/selling. Such grants are common executive compensation and do not by themselves indicate a buy/sell market signal. The derivative RSUs will convert to shares according to the stated vesting schedule; no immediate sale or exercise was reported.
