• Shares sold: 12,000; total proceeds ≈ $3,240,972.

Context

• This was an open-market sale — a routine insider disposition that does not, by itself, indicate a change in the company’s prospects. The filing does not show this was part of a trading plan (e.g., 10b5-1) nor an option exercise followed by an immediate sale.
• For retail investors: pay attention to aggregate insider activity and timing, but interpret single sales cautiously; purchases are generally more indicative of insider confidence than routine sales.
