PNR INVESTOR ALERT: Hagens Berman Notifies Pentair plc Investors of Securities Fraud Class Action Lawsuit and Upcoming Deadline

Investors in Pentair plc ( NYSE: PNR ) are alerted 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.

The expanded class period is March 11, 2025 – July 14, 2026. The lead plaintiff deadline is October 2, 2026.

The lawsuit alleges that beginning on March 11, 2025, Pentair plc and certain executives made materially false and misleading statements and omitted critical adverse operational information regarding the company'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, and that 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 complaint alleges that the artificial inflation in Pentair shares ended abruptly on July 14, 2026, after the market closed, when Pentair pre-announced preliminary second-quarter 2026 financial results that fell substantially below consensus estimates. The disclosures revealed massive revenue misses, with sales expected to be approximately $930 million 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.

Pentair also 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. 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.

The firm is closely examining the timing of these disclosures, the sudden departure of the CFO, and the severe impact of channel destocking on Pentair's financial health.

Investors who purchased or acquired Pentair common stock between March 11, 2025, and July 14, 2026, and suffered significant financial losses, have until October 2, 2026, to ask the court to appoint them as lead plaintiff.
