Context

• “Sell‑to‑cover” means shares were sold to satisfy tax withholding obligations tied to RSU vesting; these are routine and commonly do not signal a change in insider sentiment. A 10b5‑1 plan allows insiders to execute pre‑arranged trades and also indicates the trades were at least partly pre‑scheduled. For retail investors, such administrative sales are generally less informative about management’s view of the company than voluntary open‑market purchases.
