Context

• This was a grant/award (an acquisition of a derivative interest), not a sale. Derivative grants (options or RSUs) confer the right to receive shares over time and do not represent immediate sale proceeds or open-market buying. Such grants are commonly used for director compensation and should be interpreted as part of pay, not necessarily a direct buy/sell signal.
