Context

• This is a compensation grant for a director, not an open-market purchase or sale. It represents potential future ownership if the option vests and is exercised; it does not immediately increase outstanding common shares until exercised (i.e., may lead to dilution later).
• Such grants are common as director compensation; they are informational about compensation and potential future insider ownership rather than a direct bullish or bearish trading signal.
