What Happened?

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

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.

The Company also reduced its full-year 2026 guidance. Pentair now expects 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.

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.”

On this news, Pentair’s stock price fell $11.35, or approximately 15%, to close at $64.33 per share on July 15, 2026.
