Context

• This is a compensation grant (RSUs) to a director — not a market purchase or sale. RSUs do not represent voting shares until they vest and are converted into actual shares; they may be subject to taxes or withholding when they vest. Such awards are routine as part of director compensation and do not, by themselves, indicate buying or selling sentiment.
