Chief Quality & Operations Officer Karen A. Foster sells 97,423 shares (46.2% of holdings) for $1,962,998.45 in 2 transactions.

Karen A. Foster, Chief Quality and Operations Officer, executed 2 separate sales totaling 97,423 shares for $1,962,998.45, reducing her holdings from 210,665 shares to 113,242 shares—a 46.2% reduction in her stake. The sales occurred at a blended average price of $20.15, which is 1.3% above the current price of $19.90 but 30.9% below the 52-week high of $28.79, indicating the stock has declined substantially from recent highs. This is a material reduction in insider ownership by a C-suite executive during a period when the company is trading at a compressed valuation (P/E of 76.54) against mixed fundamentals: while annual revenue growth is solid at 17.0%, the company was unprofitable over its most recent full fiscal year and the stock has fallen 11.3% in the past 30 days and 19.6% over 90 days. The magnitude of the sale—nearly half her holdings liquidated in two transactions over four days—represents a significant shift in insider exposure to the company.
