Context

• Because Briseno acquired shares by exercising options and sold the same number of shares the same day, this appears to be a cashless exercise (exercise followed by immediate sale) rather than a market purchase indicating added bullish exposure. This is a common way for insiders to realize option value; it is factual reporting of transactions, not a statement of confidence or opinion about the company.
