Context
This filing reflects institutional selling by a reported 10% owner via a trustee-held position, rather than an executive or director trade. Sales by large shareholders can be routine (rebalancing or liquidity needs) and do not by themselves indicate company performance. The filing discloses a weighted-average price and a range; the filer offers to provide a per-price breakdown to the issuer or SEC upon request.
