The business in plain English
Pentair plc makes equipment that moves, filters and treats water. Its products range from pool pumps, heaters and automatic cleaners to home water softeners, commercial ice machines and large pumps for fire suppression, wastewater and flood control. It earns money by designing and manufacturing this equipment. Most of it reaches customers through wholesale and retail distributors, and some goes directly to end users and equipment makers. Revenue was $4.18 billion in fiscal 2025, which ended December 31, 2025.
Pentair reported three segments for fiscal 2025. Pool brought in 37.3% of sales, with brands such as Pentair Pool, Kreepy Krauly and Sta-Rite. Flow brought in 37.2%. It makes pumps and filtration systems under names such as Myers, Aurora and Fairbanks-Nijhuis. Water Solutions brought in 25.4% from home and commercial water treatment, under brands such as Everpure, Fleck and Manitowoc Ice. The United States supplied 70.4% of sales, developing markets 12.2% and Western Europe 11.9%.
One Pool customer accounted for about 18% of total sales in 2025, up from 15% in 2024. Demand is seasonal and peaks from roughly April to August, when warm weather lifts pool and water-supply purchases. From January 1, 2026, Pentair moved its residential and irrigation pump business from Flow into Water Solutions. On that basis, 2025 sales were $1.61 billion for Water Solutions and $1.00 billion for Flow.

What could go wrong
- Heavy reliance on one pool customer. A single Pool customer made up about 18% of Pentair's total sales in 2025, up from 15% in 2024. Losing it, or a cut or delay in its orders, could hurt results.
- Weather swings sales up and down. Pool and water-supply demand peaks from about April to August. Cool temperatures, heavy flooding or drought can hurt sales. Pentair offers discounts and longer payment terms to pull some orders earlier.
- Irish shares bring tax quirks. Pentair is incorporated in Ireland with U.K. tax residency. Share transfers may face Irish stamp duty, gifted or inherited shares may face Irish capital acquisitions tax, and tax-law changes could raise its tax rate.
- Acquisitions and goodwill could backfire. Pentair grows partly through acquisitions, such as Hydra-Stop for $292.1 million in 2025. Deals can disappoint. Goodwill, the premium paid over the value of acquired assets, is significant and could be written down.
- Debt far exceeds cash on hand. As of September 30, 2026, Pentair had about $1.48 billion of debt and $74 million of cash and investments. More borrowing, loan covenants (limits set by lenders), credit downgrades or higher rates could squeeze profits.
- Housing slowdowns, tariffs and price wars. Sales depend on housing, commercial real estate, foodservice and industrial spending. Tariffs and inflation can raise costs. In downturns, prices tend to fall as rivals compete harder.

For income and retirement investors
Pentair has raised its dividend per share for at least six straight years, from $0.76 in fiscal 2020 to $1.00 in fiscal 2025, about 5.6% a year. In fiscal 2025, dividends used 25.1% of earnings and 22% of free cash flow (cash left after paying for operations and new equipment), which leaves a cushion. The yield was 1.68% as of October 28, 2026. From fiscal 2021 to 2025, Pentair paid $733.4 million in dividends and spent $575 million repurchasing its own shares. Its share count fell 3.3% between December 2021 and September 2026.
Downturns have hit the shares hard. They lost 54.8% in the 2008 financial crisis and needed 13.5 months after the March 2009 low to recover. They fell 48.7% in the 2020 COVID crash and 42.9% in the 2022 bear market, recovering in 4.6 and 9.6 months. As of October 28, 2026, they were down 37.3% year to date. A single stock carries more risk than a diversified fund.
Questions investors ask
How does Pentair make money?
Pentair makes money by designing and manufacturing water equipment, which it supplies mostly through wholesale and retail distributors. In fiscal 2025, which ended December 31, 2025, revenue was $4.18 billion and net income was $653.8 million, or 15.7% of revenue. Pool equipment such as pumps, heaters and automatic cleaners brought in 37.3% of sales. Flow, which makes pumps and filtration systems for homes, farms, businesses and industry, brought in 37.2%. Water Solutions, including softeners, filters and commercial ice machines, brought in 25.4%.
Does Pentair raise its dividend every year?
Yes, so far. Pentair has raised its dividend per share for at least six straight years, from $0.76 in fiscal 2020 to $1.00 in fiscal 2025, about 5.6% a year. The payout is modest. Dividends used 25.1% of fiscal 2025 earnings and 22% of free cash flow, which is the cash left after operating costs and equipment spending. The yield was 1.68% as of October 28, 2026. Past increases do not guarantee future ones.
How much has Pentair stock fallen?
Sharply. As of October 28, 2026, Pentair shares were down 37.3% year to date and 40% over the prior 12 months, though they gained 22.4% in the week before that date. Business results also slipped. In the quarter ended September 30, 2026, revenue fell 4.5% and net income fell 21.3% from a year earlier. At that price the shares traded at about 16.3 times fiscal 2025 earnings, a measure called the price-to-earnings ratio.
Is Pentair an American or an Irish company?
It is legally Irish, but most of its business is American. Pentair plc is an Irish public limited company formed in 2014 and is managed from the U.K. for tax purposes. Its U.S. management office is in Golden Valley, Minnesota. Its roots trace to Pentair, Inc., a Minnesota company formed in 1966, and 70.4% of fiscal 2025 sales came from the United States. Because of the Irish structure, share transfers may be subject to Irish stamp duty, and gifted or inherited shares could face Irish capital acquisitions tax.
Which ETFs hold Pentair stock?
Pentair appears in 187 ETFs. Funds focused on water and environmental infrastructure give it the largest weights. Invesco Global Water ETF (PIO) held about 7.6% in Pentair, Global X Clean Water ETF (AQWA) about 7.4% and iShares Environmental Infrastructure and Industrials ETF (EFRA) about 5.3%. Invesco Water Resources ETF (PHO) and First Trust Water ETF (FIW) each held under 4%. Weights change over time. A fund spreads risk across many companies, but a water fund still bets on one theme.
