Context

• NPEH, LLC is a 10% owner (institutional entity), not an individual executive; sales by large shareholders can be for portfolio or liquidity reasons and do not necessarily signal company outlook.
• These were open-market sales (code S) — routine dispositions are common and, unlike purchases, are less often interpreted as a bullish signal by investors.
