Context
The cash purchase is a direct acquisition by a company insider and may be viewed by investors as a stronger signal of personal conviction than standard equity compensation. The RSU grants are typical director compensation and vest over time, so they do not immediately add tradable shares until vested. This summary is factual and does not infer motives.
