FY26 outlook (per Q4 2025 call, 2026-02-03)

Management noted continued confidence in business model and end markets, customer obsession, innovation, operational excellence, sustainability.

Key risks

Pool installed base + new construction cycle. Pool segment depends on installed base service + replacement + new pool construction. Multi-year housing cycle dynamics affect new pool builds.

Residential water consumer cycle. Flow + Water Solutions residential exposure to consumer spending + housing dynamics.

Foodservice / commercial cycle. Water Solutions has meaningful foodservice + commercial exposure. Multi-year cycle dynamics matter (Q4 -10% reflects soft foodservice).

Multi-region competitive landscape. Watts Water, Xylem, Rexnord, IDEX, Mueller Water, A.O. Smith, Whirlpool, Generac, Hayward, others compete in subsets.

Manitowoc ICE + Everpure brand dynamics. Brand portfolio + product innovation cycle critical.

Steel + commodity costs. Pumps + filtration products sensitive to steel + copper + plastics raw materials.

FX volatility. Multi-region revenue exposes Pentair to FX translation.

M&A pipeline + integration. Future portfolio actions carry integration risk.

Pricing sustainability. Multi-year pricing power requires continued value-based pricing + operational excellence.

Channel + dealer relationships. Pool + residential channel concentrated in dealer + distributor relationships.

PFAS + regulatory tailwinds. PFAS regulation drives water filtration demand; multi-year regulatory + technology evolution.

Labor + manufacturing efficiency. Multi-year manufacturing labor environment + automation execution.

Cybersecurity + IoT. Smart pool + connected products create cybersecurity exposure.

Climate + drought / flood dynamics. Water industry impacted by climate + drought + flood events (positive demand driver in some cases).

Talent retention. Engineering + manufacturing talent.

Bottom line

Pentair FY25 is the multi-segment margin expansion + record adj EPS year: revenue $4.18B (+2%); op income $858M (+7%); NI $654M (+5%); GAAP EPS $3.96 (+6%); adj EPS $5.25 (record). FCF $746M (+8%, record). Q4 2025: 5% sales growth, 15th consecutive Q margin expansion; adj op profit +9%; ROS +90bp to 24.7%; adj EPS $1.18 (+9%). Pool: Q4 +11% / FY +9%; ROS 33.8% (record). Flow: Q4 sales +9% / segment income +22%; FY ROS 23.3%. Water Solutions: Q4 -10% / FY -6%; ROS 23.9%. Strategic residential consolidation effective 2026. 60th anniversary; approach Dividend King status. PFAS Everpure + Manitowoc ICE Neo launches. Buyback $225M (+50%); dividend $164M (+8%); total debt $1.64B (-7%).

FY26 guide: adj EPS $5.25-$5.40 (+8% midpoint); sales growth 3-4%; adj op income +5-8%; FCF ~100% of NI; Q1 adj EPS $1.15-$1.18; Q1 sales +1-2%; Q1 op income +2-5%.

The risks are real — Pool installed base + new construction cycle, residential water consumer cycle, foodservice / commercial cycle, multi-region competitive landscape (Watts Water, Xylem, Rexnord, IDEX, Mueller Water, A.O. Smith, Whirlpool, Generac, Hayward), Manitowoc ICE + Everpure brand dynamics, steel + commodity costs, FX volatility, M&A pipeline + integration, pricing sustainability, channel + dealer relationships, PFAS + regulatory tailwinds, labor + manufacturing efficiency, cybersecurity + IoT, climate + drought / flood dynamics, talent retention.

But the structural thesis (leading water + flow solutions provider + residential + commercial + industrial multi-segment + Pool segment 33.8% ROS record + 15th consecutive Q margin expansion + record FY25 sales / adj operating income / ROS / adj EPS / FCF $746M + 60th anniversary approaching Dividend King + residential consolidation 2026 + PFAS Everpure + Manitowoc ICE Neo product launches + multi-year deleveraging + buyback +50%) is intact and FY25 confirms.

Quality multi-segment water + flow solutions compounder mid-cycle, with multi-year margin expansion + Pool + Flow + Water Solutions diversification + residential consolidation + product innovation + Dividend King trajectory + multi-year capital return acceleration. The 15th consecutive Q margin expansion + Q4 ROS 24.7% + Pool record 33.8% ROS + record FCF $746M + adj EPS $5.25 record + buyback +50% + multi-year deleveraging + FY26 +8% adj EPS + sales +3-4% + 100% FCF conversion creates one of the cleaner water + flow solutions compounding setups for investors seeking exposure to water industry secular tailwinds + Pool installed base + Pentair brand + Dividend King + capital return + PFAS regulation tailwind. The conservative FY26 framework + 15-quarter margin streak + product innovation + residential consolidation + multi-year capital return provides multiple paths to outperformance over a multi-year horizon. Pool cycle + residential consumer + foodservice + commodity + competitive landscape remain ongoing risks, but the multi-segment diversification + margin expansion track record + Pool moat + brand strength + dividend track record support continued compounding through cycles.
