Context

• RSUs are a form of equity compensation that convert to shares upon vesting; they are not an open-market purchase or sale and do not necessarily signal immediate bullish or bearish sentiment. Taxes are typically due when RSUs vest (or upon delivery, depending on plan elections). For retail investors, awards to directors are common as part of compensation and should be considered alongside other insider transactions and company fundamentals.
