Pentair plc investors who bought securities between April 28, 2026 and July 14, 2026 have until October 2, 2026 to seek appointment as lead plaintiff (the investor who directs the case) in a proposed class action, Glancy Prongay Wolke & Rotter LLP said. The lawsuit follows Pentair's July 14, 2026 preliminary second-quarter results, which said inventory destocking (retailers and distributors reducing stock) in the Pool channel cut Pool segment sales by about $170 million and segment income by about $105 million. Pentair then said second-quarter 2026 sales were expected to be down 17% versus a prior guide of about 1%, while full-year 2026 sales were expected to fall about 4% to 7% versus a prior guide of up 2% to 4%. The company also announced the immediate departure of its Chief Financial Officer. Pentair shares fell $11.35, or 15%, to close at $64.33 on July 15, 2026, on unusually heavy volume. The complaint alleges investors were not told about significant Pool channel destocking and its effect on sales and operating income, leaving earlier positive statements about the business, operations and prospects materially misleading or without a reasonable basis.
