Cooper's 2026 fourth-quarter forecasts missed Wall Street's targets

Cooper, a medical-device company, released its Q3 numbers yesterday, reporting adjusted earnings of $1.15 per share. While that beat estimates, it missed estimates on its top-line, reporting $1.07 billion in sales.

The real issue was the company's Q4 earnings forecast of $1.05 per share to $1.09 per share, which came in well below Wall Street's $1.19 estimate.
