COMPLAINT ALLEGATION SUMMARY:
Pentair sells various water solutions, such as filtration, supply pumps, and treatment products. Pentair operates through three segments: Flow, Water Solutions, and Pool.

The complaints allege that, throughout the Class Period, Defendants made materially false and/or misleading statements, as well as failed to disclose material facts about the company’s business, operations, and prospects. Specifically, Defendants misrepresented and/or failed to disclose that: (1) the Pool segment was experiencing significant destocking of inventory; (2) the destocking adversely affected the company’s sales and operating income; and (3) as a result of the foregoing, Defendants’ statements about the company’s business, operations, and prospects were materially false and misleading and/or lacked a reasonable basis at all relevant times.

WHY DID PENTAIR’S STOCK DROP?
On July 14, 2026, Pentair released its preliminary second quarter 2026 financial results, revealing that the inventory destocking in the Pool segment “negatively impacted Pool segment sales by approximately $170 million and Pool segment income by approximately $105 million.” As a result, second quarter sales were expected to decline by 17%, compared to 1% from the prior guidance. On this news, the price of Pentair’s stock fell 15%.

THE LEAD PLAINTIFF PROCESS:
The Private Securities Litigation Reform Act of 1995 permits any investor who purchased or acquired Pentair securities during the Class Period to seek appointment as lead plaintiff in the Pentair class action lawsuits. A lead plaintiff is a representative party that acts on behalf of other class members in directing the litigation. In order to be appointed lead plaintiff, the Court must determine that the class member’s claim is typical of the claims of other class members, and that the class member will adequately represent the class. Your ability to share in any recovery is not, however, affected by the decision whether or not to serve as a lead plaintiff. Filling out the online form above or communicating with any counsel is not necessary to participate or share in any recovery achieved in this case. Any member of the purported class may move the court to serve as a lead plaintiff through counsel of his/her choice, or may choose to do nothing and remain an inactive class member.
