Hagens Berman expands Pentair securities class period to March 2025

By Atlas Watchline Staff · Legal · September 3, 2026

Hagens Berman says investors in Pentair plc have until Oct. 2, 2026, to seek lead-plaintiff status in an expanded securities fraud class action.

Hagens Berman Sobol Shapiro LLP said on Sept. 3, 2026, that investors in Pentair plc are being notified about an expanded securities fraud class action and a lead-plaintiff deadline of Oct. 2, 2026.

The firm said the proposed class period now runs from March 11, 2025, through July 14, 2026. It had previously been stated as April 28, 2026, through July 14, 2026.

According to the notice, the lawsuit alleges that Pentair and certain top executives made materially false and misleading statements and omitted adverse information about the company’s financial health, channel inventory and internal controls. The notice does not set out Pentair’s response.

Hagens Berman said the alleged stock inflation ended after the market closed on July 14, 2026, when Pentair pre-announced preliminary second-quarter 2026 results. The notice says those results fell below consensus estimates and revealed operational headwinds.

The firm said Pentair’s stock fell 15% in one session, losing $11.35 to close at $64.33 on July 15, 2026.

Reed Kathrein is identified in the notice as the Hagens Berman partner leading the investigation. The notice also says investors who purchased or acquired Pentair common stock between March 11, 2025, and July 14, 2026, and suffered significant financial losses may ask the court to appoint them lead plaintiff by Oct. 2, 2026.

Hagens Berman also included contact information for investors and referenced the SEC whistleblower program, saying awards may total up to 30% of successful SEC recoveries.

Investors who believe they qualify would need to seek lead-plaintiff status by Oct. 2, 2026, under the notice.
