Pentair (PNR) FY2025 results: revenue $4.2 billion, up 2.3% on the year

Pentair is an Irish public limited company formed in 2014 and tax resident in the U.K., and it designs, manufactures and sells products that move, treat and filter water for residential, commercial and industrial users. It is the successor to Pentair Ltd., a Swiss corporation formed in 2012, and to Pentair, Inc., a Minnesota corporation formed in 1966. Its registered principal office is in Twickenham, London, and its United States management office is in Golden Valley, Minnesota. Through 2025 it reported three segments: Flow, Water Solutions and Pool.

Flow

Flow designs, manufactures and sells fluid treatment and pump products and systems, among them pressure vessels, gas recovery solutions, membrane bioreactors, wastewater reuse systems, advanced membrane filtration, separation systems, specialty insertion valves, line stop fittings and installation equipment, water disposal, water supply, fluid transfer, turbine and solid handling pumps, and agricultural spray nozzles. Applications run from fluid delivery, ion exchange and desalination through food and beverage, separation for the oil and gas industry, and residential and municipal wells to water treatment, pressure boosting, fire suppression, flood control and crop spray. In 2025 the residential and irrigation flow businesses, which sell pumps for homes and agriculture, were approximately 36% of Flow sales, the commercial and infrastructure businesses selling larger pumps for fire suppression, water supply, wastewater and flood control were approximately 30%, and the industrial solutions business covering industrial process and air filtration and sustainable gas was approximately 34%. Brand names include Pentair Flow, Aurora, Berkeley, Codeline, Fairbanks-Nijhuis, Haffmans, Hydromatic, Hypro, Jung Pumpen, Myers, Sta-Rite, Shurflo, Südmo and X-Flow.

Water Solutions

Water Solutions designs, manufactures and sells commercial and residential water treatment products and systems, including pressure tanks, control valves, activated carbon products, commercial ice machines, conventional filtration products and point-of-entry and point-of-use treatment systems. They go into whole home water filtration, drinking water filtration and water softening, and into commercial water management and filtration in foodservice operations. In 2025 the commercial business was approximately 66% of the segment's sales and the residential business approximately 34%. Brand names include Pentair Water Solutions, Everpure, Fleck, Manitowoc Ice, Pentek and RainSoft.

Pool

Pool designs, manufactures and sells a complete line of energy-efficient residential and commercial pool equipment and accessories: pumps, filters, heaters, lights, automatic controls, chlorinators, automatic cleaners, maintenance equipment and pool accessories, used in pool maintenance, repair, renovation, service, construction and aquaculture. Its brand names are Pentair Pool, Kreepy Krauly, Pleatco and Sta-Rite. One customer in the Pool business represented approximately 18% of consolidated net sales in 2025 and approximately 15% in 2024. End-user demand follows warm weather trends and has historically been at seasonal highs from April to August, a spike the company partly smooths with advance sale early buy programmes carrying extended payment terms or additional discounts.

The 2026 reshuffle

From 1 January 2026 the residential and irrigation flow business moved out of Flow and into Water Solutions, taking with it fluid transfer pumps, agricultural spray nozzles and certain water disposal and water supply pumps, along with the Berkeley, Hypro, Jung Pumpen, Sta-Rite and Shurflo brands. Flow therefore no longer serves wholesale and retail distribution customers in residential or agricultural markets, and the weather-driven seasonality moves with the business into Water Solutions. The Pool segment is unchanged, and the filing states that the change does not alter the competitive landscape of either segment.

Hydra-Stop, LLC, which makes specialty insertion valves, line stop fittings and installation equipment, was bought on 17 September 2025 for $292.1 million in cash net of cash acquired, inside the Flow segment; G & F Manufacturing, LLC, which makes and services pool heat pumps, was bought in December 2024 for $116.0 million in cash net of cash acquired, made up of $108.0 million upfront and a contingent earn-out tied to defined operating results in the following two years. The principal manufacturing materials are mild steel, stainless steel, electronic components including drives and motors, plastics such as resins, fiberglass and epoxies, metals and paint, all bought on the open market, and some finished goods are purchased for resale. At 31 December 2025 there were approximately 9,000 employees worldwide, approximately 49% of them in the U.S., a small portion of those unionised, and employees in certain countries outside the United States, primarily in Europe, are represented by a union, works council or employee association.
