Context

• This was an outright sale of existing shares rather than an exercise of options or receipt of an award. Sales by directors can be routine (e.g., portfolio rebalancing or trust/estate needs); the filing alone does not explain motivation. Purchases tend to be more directly interpreted as insider bullishness.
