Pomerantz says class action filed against Pentair over July guidance cut

By Atlas Watchline Staff · Legal · August 13, 2026

Pomerantz LLP said a class action has been filed against Pentair plc over claims tied to the company’s July 14, 2026 earnings update and revised outlook.

Pomerantz LLP said on Aug. 13 that a class action lawsuit has been filed against Pentair plc and certain officers and/or directors, with a lead-plaintiff deadline of Oct. 2, 2026.

The investor alert concerns Pentair’s July 14, 2026 press release, which said preliminary second-quarter results and full-year guidance had changed sharply. Pomerantz said the case concerns whether Pentair engaged in securities fraud or other unlawful business practices.

According to the alert, Pentair said second-quarter sales were expected to be about $930 million, down 17% from prior guidance of about 1% growth. Pentair attributed that change mainly to the adverse impact of Pool channel inventory.

The notice also said Pentair expected earnings per diluted share from continuing operations to be about $0.80, compared with prior guidance of $1.39 to $1.42. Adjusted earnings per share were expected to be about $1.12, versus prior guidance of $1.47 to $1.50. Pentair attributed those changes to the adverse impact of Pool channel inventory and the positive impact of IEEPA refunds.

For full-year 2026, Pentair said sales were expected to be down about 4% to 7%, compared with prior guidance of up 2% to 4%. The company said the change was mostly due to destocking in the Pool channel and right sizing of channel inventory ahead of the 2027 pool season.

The July 14 release also announced the departure of Chief Financial Officer Nicholas Brazis, who was leaving to pursue another opportunity at a private company, according to the alert.

Pomerantz said the stock fell $11.35, or 15%, to close at $64.33 on July 15, 2026 after the news.

The notice said investors who purchased or otherwise acquired Pentair securities during the class period can seek appointment as lead plaintiff by Oct. 2. It identified Danielle Peyton as the contact for inquiries and said email requests should include a mailing address, telephone number and share count.
