Levi & Korsinsky Reminds Pentair plc Investors of the Pending Class Action Lawsuit With a Lead Plaintiff Deadline of October 2, 2026 - PNR

Important Notice Regarding Alleged Pool Channel Destocking Misrepresentations: Pentair's Pool segment allegedly absorbed roughly $250 million in lost sales and $155 million in lost income while investors were told full year sales would rise.

NEW YORK, Aug. 26, 2026 /PRNewswire/ -- Levi & Korsinsky, LLP notifies investors in Pentair plc (NYSE: PNR) that a class action lawsuit has been filed on behalf of shareholders who purchased securities between April 28, 2026 and July 14, 2026. Find out if you could qualify to recover your losses. You may also contact Joseph E. Levi, Esq. at [email protected] or (212) 363-7500.

The complaint alleges that Pool channel destocking reduced Pool segment sales by approximately $250 million and Pool segment income by approximately $155 million for full year 2026, with roughly $170 million of the sales impact and $105 million of the income impact landing in the second quarter alone. Full year 2026 sales guidance was revised to down approximately 4 percent to 7 percent from up 2 percent to 4 percent.

The Alleged Pool Channel Destocking Problem

Pentair's Pool segment sells energy-efficient pool equipment and accessories through a distribution channel, and in fiscal 2025 that segment accounted for approximately 37 percent of net sales and 46 percent of reportable income. According to the lawsuit, significant destocking was already occurring in that channel during the Class Period, meaning distributors were drawing down existing inventory rather than placing new orders. The lawsuit contends investors were not told this was happening while the Company continued to project growth.

How the Alleged Destocking Affected Reported Guidance

On July 14, 2026, after the market closed, Pentair issued preliminary second quarter 2026 results and revised full year guidance, attributing the shortfall largely to destocking of inventory in the Pool channel and right sizing of channel inventory in preparation for the 2027 pool season. Full year GAAP EPS guidance was cut to approximately $3.90 to $4.10 from $4.83 to $4.93, and full year adjusted EPS guidance was cut to approximately $4.60 to $4.80 from $5.30 to $5.40.

Key Pool Channel Destocking Allegations for Shareholders

• The complaint alleges the Company failed to disclose that significant destocking of inventory was occurring in the Pool channel.
• As a result, the lawsuit contends, sales and operating income were adversely affected in ways not communicated to the market.
• The lawsuit alleges positive statements about the Company's business, operations, and prospects were therefore materially misleading or lacked a reasonable basis.
• Full year 2026 Pool segment sales were estimated to be reduced by approximately $250 million from the destocking.
• Full year 2026 Pool segment income was estimated to be reduced by approximately $155 million.
• Inventory statements in the Form 10-Q for the period ended March 31, 2026 are challenged in the action.

"This case presents important questions about inventory and channel disclosure obligations in the water solutions sector, particularly where a single segment allegedly generated a $155 million income impact that shareholders learned about only after the fact," -- Joseph E. Levi, Esq.

Q: Who is eligible to join the PNR investor lawsuit?A: Investors who purchased PNR stock or securities between April 28, 2026 and July 14, 2026 and suffered financial losses may be eligible. Eligibility is based on purchase date and documented losses, not on whether you still hold the shares.

Q: What is a lead plaintiff and why does it matter?A: A lead plaintiff is the investor appointed by the court to represent the entire class.

Applications to serve as lead plaintiff must be filed by October 2, 2026.

Q: What if I already sold my PNR shares, can I still recover losses?A: Yes. Eligibility is based on when you purchased, not whether you still hold the shares. Investors who bought during the Class Period and sold at a loss may still be eligible to participate.
