Pentair (PNR) Cuts Guidance On Pool Weakness As Its Valuation Case Gets Retested

Pentair trims guidance and explains what changed in its pool business

Pentair (PNR) cut its second quarter 2026 and full year 2026 guidance, pointing to weaker pool sales, a sharper pool channel inventory reset, and pressure from higher interest rates and inflation.

The company now expects second quarter sales of about $930 million, operating income of roughly $165 million and diluted EPS from continuing operations near $0.80, all below its earlier outlook.

For the full year 2026, Pentair is guiding sales to be down about 4% to 7% instead of previously guided growth, with operating income from continuing operations expected to be down roughly 1% to 6%.

Management also lowered its full year GAAP diluted EPS outlook to a range of $3.90 to $4.10 and identified pool channel destocking and inventory right sizing ahead of the 2027 pool season as key drivers.
