Pentair shares were sharply lower ahead of the opening bell after the water treatment and solutions company lowered its second-quarter and full-year sales guidance, citing declining sales in its pool segment.

In premarket trading in New York, the shares dropped 23% to $58. As of Tuesday's close, the stock had already fallen more than 25% this year.

Pentair said it now expects second-quarter sales of $930 million, where it previously forecast growth of 1%.

For 2026, the company now projects sales will decline 4% to 7%. It had guided for sales to increase by between 2% and 4%. It recorded revenue of $4.18 billion last year, according to FactSet.

Pentair said it has appointed Bob Fishman as interim chief financial officer after finance chief Nicholas Brazis resigned to pursue an opportunity at a private company. Fishman was the company's CFO from 2020 to March of this year before resigning.
