What Is The Lawsuit About?

The lawsuit has been filed on behalf of investors who purchased securities during the period of March 11, 2025 and July 14, 2026, inclusive (“the Class Period”). The lawsuit alleges that Pentair made materially false and/or misleading statements and failed to disclose to investors: (i) that there was significant destocking of inventory in the Pool channel; and (ii) as a result, the Company’s sales and operating income were adversely affected.

On February 3, 2026, Pentair announced its fourth quarter and full year 2026 financial results, revealing that Pentair’s net sales were on track to grow only 1% to 2% for its first fiscal quarter of 2026, missing analyst consensus estimates by tens of millions of dollars. During the related earnings call, Pentair disclosed that net sales growth in its critical Pool business had been flat. Pentair concurrently announced that the Company’s Chief Transformation Officer & Chief Supply Officer, Steve Pilla, was departing. On this news, Pentair’s stock price fell $10.72, or over 10%, to close at $94.79 per share on February 3, 2026.

Then, on April 28, 2026, Pentair announced its first quarter 2026 financial results, revealing that the Company had cut its annual net sales guidance for Pool to a range of 1% to 3% net sales growth. During the related earnings call, CFO Nicholas J. Brazis further revealed that the downward revision reflected the need of channel partners to “reduce purchases in Q2 and Q3” in light of “sell-through dynamics” experienced in the first quarter. On this news, Pentair’s stock price fell $11.43, or more than 12%, to close at $ 80.84 per share on April 29, 2026.

On July 14, 2026, Pentair released its preliminary second quarter 2026 financial results, revealing that “the [Company] 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 previous guide of up approximately 1 percent,” and full year 2026 sales were expected to be “down approximately 4 percent to 7 percent versus previous guide of up 2 percent to 4 percent.” The Company explained that second quarter performance “was impacted by a decline in Pool sales largely attributed to a more pronounced inventory realignment with major channel partners than previously estimated and worsening business conditions, including higher interest rates and inflation.” 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.
