Context

• This filing shows option exercises followed by an immediate open-market sale of the 16,452 shares on 8/3 (commonly a cash-out after exercise). The remaining 5,644 exercised shares reported on 8/4 were not sold in this filing and may be held. Sales under a 10b5-1 plan are pre-arranged and are often routine (tax planning, diversification, liquidity) rather than an ad hoc signal about company prospects.
