Context

• This was a straightforward share sale (transaction code S). Sales by directors can be routine (diversification, taxes, planned sales) and do not necessarily signal negative views; purchases generally carry more informational weight. The fractional share quantity (12,190.833) may reflect the mechanics of how the shares were disposed but the filing gives no reason for the sale.
