As detailed below, the complaint alleges that the Company and its executives violated federal securities laws by making false and/or misleading statements and/or failing to disclose that: (1) that there was significant destocking of inventory in the Pool channel; (2) that, as a result, the Company's sales and operating income were adversely affected; and (3) that, as a result of the foregoing, Defendants' positive statements about the Company's business, operations, and prospects were materially misleading and/or lacked a reasonable basis.

On July 14, 2026, after the market closed, Pentair released its preliminary second quarter 2026 financial results, disclosing that "the [C]ompany estimates that the destocking of inventory in the Pool channel negatively impacted Pool segment sales by approximately $170 million and Pool segment income by approximately $105 million."

As a result, second quarter 2026 sales were expected to be "down 17 percent versus the prior guide of approximately 1 percent" and full year 2026 "[s]ales are expected to be down approximately 4 percent to 7 percent versus prior guide of up 2 percent to 4 percent[.]"

The Company also announced the departure of its Chief Financial Officer, effective immediately.

On this news, Pentair's stock price fell $11.35, or 15%, to close at $64.33 per share on July 15, 2026, on unusually heavy trading volume.

The court-appointed lead plaintiff is the investor with the largest financial interest in the relief sought by the class who is adequate and typical of class members who directs and oversees the litigation on behalf of the putative class.

Any member of the putative class may move the Court to serve as lead plaintiff through counsel of their choice, or may choose to do nothing and remain an absent class member.

Your ability to share in any recovery is not affected by the decision to serve as a lead plaintiff or not.
