PNR INVESTORS: Robbins Geller Rudman & Dowd LLP Files Class Action Lawsuit Against Pentair plc and Announces Opportunity for Investors with Substantial Losses to Lead Class Action Lawsuit Before October 2, 2026 Deadline

The law firm of Robbins Geller Rudman & Dowd LLP announces that purchasers of Pentair plc (NYSE: PNR) ordinary shares between March 11, 2025 and July 14, 2026, both dates inclusive (the "Class Period"), have until October 2, 2026 to seek appointment as lead plaintiff of the Pentair class action lawsuit.

The Pentair class action lawsuit charges Pentair as well as certain of Pentair's top current and former executive officers with violations of the Securities Exchange Act of 1934.

Pentair is a global manufacturer of water solution products.

The Pentair class action lawsuit alleges defendants throughout the Class Period made false and/or misleading statements and/or failed to disclose that: (i) Pentair's 80/20 program had failed to improve Pentair's business and operations and had instead materially impaired Pentair's longstanding commercial relationships, alienated its customers, and created widespread customer dissatisfaction, particularly within Pentair's Pool segment; (ii) Pentair was losing business and market share, as a significant portion of its Pool customers had turned to competitors in response to Pentair's 80/20 program initiatives, which had more than offset any purported benefits to Pentair's business and financial results as a result of the implementation of the 80/20 program; (iii) Pentair's implementation of the 80/20 program had caused certain of its remaining Pool customers to buy inventory in excess of their current needs in advance of future price increases, cannibalizing Pentair's future sales; (iv) Pentair's remaining Pool customers had received rebates at rates above historical norms, which had artificially inflated Pentair's sales and revenue in the short-term at the expense of future periods; and (v) as a result of the above, Pentair was acutely exposed to material, undisclosed risks of significant financial and operational harms as a result of Pentair's implementation of its 80/20 program.

Then, on April 28, 2026, Pentair announced results for its first fiscal quarter ending March 31, 2026, revealing that Pentair had cut its annual net sales guidance for Pool to a range of 1% to 3% net sales growth.

During the related earnings call, defendant Nicholas J. Brazis further revealed that the downward revision reflected the need of channel partners to "reduce purchases in Q2 and Q3" in light of "sell-through dynamics" experienced in the first quarter.
