Pentair Announces Preliminary Financial Results, Reduces Full-Year Financial Guidance & Reports CFO’s Departure

On July 14, 2026, Pentair announced preliminary financial results for the second quarter of 2026, substantially reduced its full-year financial guidance, and announced the departure of its Chief Financial Officer.

Pentair disclosed that it expected second-quarter sales of approximately $930 million, representing a decline of approximately 17%, compared with the Company’s prior expectation of approximately 1% sales growth. Pentair also disclosed that second-quarter adjusted earnings per share were expected to be approximately $1.12, substantially below the Company’s previous guidance of between $1.47 and $1.50 per share.

Pentair further reduced its full-year 2026 guidance, expecting annual sales to decline approximately 4% to 7% compared with its prior forecast for sales growth of approximately 2% to 4%. Pentair also reduced its expected adjusted earnings per share to between $4.60 and $4.80, compared with its previous guidance of between $5.30 and $5.40 per share.

Following these disclosures, the price of Pentair common stock declined sharply trading down more than 15% during intraday trading on July 15, 2026. 

Class Action Filed on Behalf of Pentair Investors

On August 3, 2026, a class action lawsuit alleging violations of federal securities laws was filed against Pentair on behalf of persons and entities that purchased or otherwise acquired Pentair securities between April 28, 2026 and July 14, 2026, inclusive (the “Class Period”).

According to the complaint, throughout the Class Period, the Pentair Defendants allegedly made materially false and/or misleading statements and failed to disclose material adverse facts concerning the Company’s business, operations, and prospects. Allegedly, the Pentair Defendants failed to disclose that significant inventory destocking in the Pool channel was adversely affecting the Company’s sales and operating income. As a result, the complaint alleges that Defendants’ positive statements about Pentair’s business, operations, and prospects were materially misleading and/or lacked a reasonable basis.

New Class Action Expands the Pentair Class Period

On August 12, 2026, a securities class action lawsuit was filed against Pentair on behalf of investors who purchased Pentair ordinary shares between March 11, 2025 and July 14, 2026, both dates inclusive (“Expanded Class Period”).

According to the complaint, the Defendants allegedly made materially false and misleading statements concerning the implementation and performance of Pentair’s “80/20” sales program. The complaint alleges that the program impaired longstanding commercial relationships, caused widespread customer dissatisfaction, and led customers—particularly within Pentair’s Pool segment—to move business to competitors.

The complaint further alleges that the Defendants failed to disclose that certain Pool customers purchased inventory beyond their current needs ahead of anticipated price increases and received rebates above historical norms. These practices allegedly inflated short-term sales and revenue at the expense of future periods and exposed Pentair to undisclosed operational and financial risks.

On July 14, 2026, Pentair disclosed that customer destocking had reduced second-quarter Pool segment net sales by approximately $170 million. The complaint alleges that, as the relevant information was revealed, Pentair ordinary shares declined more than 40% from their Class Period high, causing investors substantial financial losses.
