Pentair shares fall 10.44% after hours as Water Solutions segment sales drop 10% in Q4, dragging full-year revenue down 6%.

Pentair fell 10.44% in after-hours trading following a sharp sales decline in its Water Solutions segment, which reported a 10% year-over-year drop in Q4 sales and a 6% annual decline. The earnings report highlighted weaker demand in this key division, with ROS contracting 60 basis points in Q4 and 3% core sales declines. Analysts cited concerns over margin pressures and growth sustainability, compounded by downgrades from TD Cowen and Barclays. While the company announced leadership changes and a dividend increase, the immediate trigger was the disappointing Water Solutions performance, which overshadowed broader 5% revenue growth and strong Pool segment results.
