Event Summary

Multiple law firms, including Bronstein, Gewirtz & Grossman, LLC, Pomerantz LLP, Hagens Berman, Kaplan Fox & Kilsheimer, Schall Brown & Schwartz LLP, Glancy Prongay & Murray, and Rosen Law Firm, have filed or announced securities fraud class action lawsuits against Pentair plc (NYSE: PNR) and certain officers. The lawsuits allege that during the Class Period from April 28, 2026 to July 14, 2026, Pentair made materially false and misleading statements and failed to disclose significant destocking of inventory in its Pool channel, which adversely affected sales and operating income. On July 14, 2026, Pentair pre-announced preliminary second-quarter 2026 results that fell far below expectations, including sales of approximately $930 million versus prior guidance of $1.14 billion, and slashed its full-year 2026 guidance. The company also announced the immediate departure of CFO Nicholas Brazis after only four months in the role. Following these disclosures, Pentair's stock price fell 15% on July 15, 2026, closing at $64.33 per share. Investors who purchased Pentair securities during the Class Period have until October 2, 2026, to seek lead plaintiff status.
