Context

This is a performance-based compensation award (not an open-market buy or sale). No cash was exchanged and no shares were immediately issued — the RSUs are contingent and subject to future vesting conditions (including continued service). Such awards are common for executives and do not by themselves indicate a buy or sell signal.
