Cooper Companies shares fell $9.31, or 14.6%, to a 52-week closing low of $54.17 after CooperVision disclosed U.S. channel inventory reductions, a roughly $30 million quarterly revenue shortfall versus Wall Street consensus and weaker organic-growth guidance. The company cut its fiscal 2026 CooperVision organic-growth outlook to 1%-2%, with third-quarter growth expected to decline 1% at the midpoint and fourth-quarter growth guided to negative 2% to flat. Hagens Berman and Levi & Korsinsky are separately investigating whether Cooper adequately disclosed sales practices, growth assumptions and inventory conditions; CooperVision represented roughly 67% of Cooper's fiscal 2025 consolidated sales.
