Context

• NPEH is a 10% owner (institutional/entity), not necessarily an executive; such institutional sales can be portfolio-management actions and do not necessarily reflect insider views on company prospects.
• These were straight sales (transaction code S) in multiple open-market trades — not option exercises, awards, or gifts.
