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.
