PENTAIR PLC CLASS ACTION LAWSUITS - COMPLAINT ALLEGATION SUMMARY: Pentair sells various water solutions, such as filtration, supply pumps, and treatment products. Pentair operates through three segments: Flow, Water Solutions, and Pool. The complaints allege that, throughout the Class Period, Defendants made materially false and/or misleading statements, as well as failed to disclose material facts about the company's business, operations, and prospects. Specifically, Defendants misrepresented and/or failed to disclose that: (1) the Pool segment was experiencing significant destocking of inventory; (2) the destocking adversely affected the company's sales and operating income; and (3) as a result of the foregoing, Defendants' statements about the company's business, operations, and prospects were materially false and misleading and/or lacked a reasonable basis at all relevant times. Why did Pentair's Stock Drop? On July 14, 2026, Pentair released its preliminary second quarter 2026 financial results, revealing that the inventory destocking in the Pool segment "negatively impacted Pool segment sales by approximately $170 million and Pool segment income by approximately $105 million." As a result, second quarter sales were expected to decline by 17%, compared to 1% from the prior guidance. On this news, the price of Pentair's stock fell 15%.

PNR alert: Hagens Berman notifies Pentair plc (NYSE: PNR) Investors of Expanded Class Period in new securities class action lawsuit and upcoming Lead Plaintiff Deadline. Aug 14, 2026, 20:30 ET SAN FRANCISCO, Aug. 14, 2026 /PRNewswire/ - Hagens Berman Sobol Shapiro LLP alerts investors in Pentair plc (NYSE: PNR) that a securities fraud class action lawsuit filed against the company has been expanded to cover an earlier class period. Investors who suffered substantial losses are urged to submit their losses now. CASE DETAILS Expanded Class Period: March 11, 2025 - July 14, 2026 (Previously April 28, 2026 - July 14, 2026) Lead Plaintiff Deadline: Oct. 2, 2026 Contact Hagens Berman: Visit www.hbsslaw.com/cases/pentair, email [email protected], or call (844) 916-0895 ALLEGED MISCONDUCT & EXPANDED CLASS PERIOD The new class action lawsuit alleges that beginning on March 11, 2025, Pentair plc and certain of its top executives made a series of materially false and misleading statements and omitted critical adverse operational information regarding Pentair's financial health, channel inventory, and internal controls. Specifically, the lawsuit alleges Defendants failed to disclose that: * Pentair was experiencing severe, undisclosed channel inventory destocking - particularly within its core Pool segment. * The company engaged in unsustainable channel-loading and sales practices with distributors to artificially inflate short-term financial metrics. * As a result, Pentair's positive statements regarding its business, full-year financial guidance, and operating income lacked a reasonable basis. THE DISCLOSURE & MARKET REACTION The complaint alleges that the artificial inflation in Pentair shares came to an abrupt end on July 14, 2026, after the market closed, when Pentair shocked investors by pre-announcing preliminary second-quarter 2026 financial results that fell substantially below consensus estimates. The disclosures revealed severe operational headwinds: * Massive Revenue Miss: Sales were expected to be approximately $930 million - a drastic miss against prior forecasts of $1.14 billion. The company disclosed that inventory destocking in the Pool channel negatively impacted Pool segment sales by approximately $170 million and income by approximately $105 million. * Full-Year Guidance Slashed: Pentair dramatically cut its full-year 2026 outlook, reversing earlier projections. Full-year sales were projected to be down approximately 4% to 7%, compared to prior guidance of up 2% to 4% growth. * Abrupt CFO Departure: Compounding the shock, Pentair announced the immediate departure of its Chief Financial Officer, Nicholas Brazis, after serving in the role for only four months, raising questions regarding internal controls and financial reporting. Following these disclosures, Pentair's stock price plummeted 15% in a single session - losing $11.35 per share to close at $64.33 on unusually heavy trading volume on July 15, 2026. "We are closely examining the timing of these disclosures, the sudden departure of the CFO after only four months, and the severe impact of channel destocking on Pentair's financial health," said Reed Kathrein, the Hagens Berman partner leading the firm's investigation of the alleged claims. What Affected PNR Investors Should Do If you purchased or acquired Pentair common stock between March 11, 2025, and July 14, 2026, and suffered significant financial losses, you have until October 2, 2026, to ask the court to appoint you as lead plaintiff.
