Context

• RSUs are a form of equity compensation that convert to shares upon vesting; this is a compensation grant rather than an open-market purchase or sale and does not, by itself, indicate a buy/sell signal.
• The award includes standard vesting and change-of-control provisions; the filing does not state whether shares will be sold at vesting or held.
