Context

As a 10% owner, these sales are large and likely reflect holdings managed through trusts/entities rather than routine employee trades; such sales are common for estate planning, diversification, or liquidity and do not by themselves indicate company performance expectations. Purchases typically carry more direct signaling value than open-market sales.
