Context
RSU grants are compensation awards that convert into shares only when they vest; they carry vesting conditions and may be forfeited on departure. A sale executed under a 10b5-1 plan is a pre-arranged trade and is generally treated as routine rather than an ad-hoc sell signal. This filing records a routine disposal and a contemporaneous compensation grant — factual events rather than statements of intent.
