Context RSUs are forward-looking compensation: they do not represent immediately transferable shares until they vest. Such grants are routine executive compensation and do not by themselves indicate a buy or sell signal. The long-delayed vesting (years 6–8) ties pay to multi-year retention and performance conditions rather than short-term trading.
