Is Pentair stock undervalued?

TickerWorth's fair-value range for Pentair plc (PNR) is $56.78 – $113.44 against a market price of $52.47. Priced below our range. We publish a range here, not one number, so we do not call it over- or undervalued. This is a model estimate, not investment advice.

Pentair (PNR) DCF valuation and fair value

Our fair-value range for Pentair plc (PNR) is $56.78 – $113.44, built on a 9.6% discount rate (WACC) and 2.5% terminal growth. It blends our discounted-cash-flow model with other valuation lenses. Every assumption is listed on this page with its source.

What growth is priced into Pentair stock?

Today's price implies revenue growth of −0.1% a year for 5 years; our model assumes 2.1% a year on average over the same horizon. This is a reverse DCF: it holds our cash-flow model's other inputs and solves for the revenue growth that makes the model equal today's price of $52.47. A model estimate, not investment advice.

Where the numbers come from

Hand-researched model

What the modeller flagged

CYCLICAL FLAG FIRES ON PURPOSE. Year 1 is -5.5% revenue growth because that is management's guidance midpoint; any negative forecast year makes the site treat Pentair as a cyclical and publish the fair value as a RANGE rather than a point. That is the honest label for a company in a pool-channel inventory trough: the point estimate leans heavily on Year 2's rebound, which is management's plan, not a fact.
THE 2027 REBOUND IS THE WHOLE STORY. Management's call framing (Pool ~$1,250M in 2026 -> ~$1,450M in 2027, i.e. back to sell-through) is the anchor for Year 2's +6%. If dealers stay cautious through the 2027 season and Pool only recovers half of that, Year 2 is ~+3.5% and the value falls ~$1.4/share — small on its own, because the margin path matters more than one year's volume; if Pool sell-through itself is shrinking (the release cites higher rates and inflation), the margin assumption fails too and the loss compounds.
TERMINAL VALUE IS ~72% OF ENTERPRISE VALUE — high but below the 75% danger line, because a ~9.6% WACC discounts the far future hard.
YEAR-1 FCF vs REPORTED: the model's 2026 unlevered FCF (~$721M) is close to FY2025's reported $748.4M despite the down year, because falling revenue releases working capital. Treat Year 1 as flattered by that release; Year 2 gives it back.
IEEPA TARIFF REFUNDS (~$35-50M in 2026) sit inside the Year-1 margin and will not recur; restructuring/transformation (~$87M in 2026) is about double normal. They roughly offset in 2026, and Years 2-5 assume neither the refund nor the elevated restructuring.
SBC (~$37M in FY2025, 0.9% of revenue) stays expensed inside GAAP operating income; the dilution is captured by the weighted-diluted count — and that count is falling because Pentair buys back more than it issues.

Why PNR gets a range, not one number

At a recent price of $52.47, Pentair plc (PNR) sits below every lens we ran: our valuation lenses put the business somewhere between $56.78 and $113.44 per share. For a cyclical we value through the cycle we publish a range only (peer multiples and our researched mid-cycle DCF): where in the cycle the business sits decides where in that range it lands, and a single figure would claim we know that precisely. This is an educational model, not a price target or a recommendation.

Read the full reasoning

The valuation discounts Pentair plc's projected free cash flows at a weighted-average cost of capital (WACC) of 9.6%, with a long-run terminal growth rate of 2.5%. About 72% of the enterprise value comes from the terminal value — the portion beyond the explicit forecast window — which is typical for a stable, cash-generative business and a reminder that small changes in the discount rate or terminal growth assumption swing the intrinsic value meaningfully.

Running the DCF in reverse — solving for the growth the current price already assumes — the market is implying roughly -0.1% annual revenue growth for PNR. Our base case instead compounds to about 2.1% a year over the same forecast, so the market is pricing in slower growth than our base case. The reverse-DCF is a quick sanity check: it reframes 'is this stock cheap?' as 'do I believe the growth the price requires?' rather than arguing over a single point estimate of fair value.

Sensitivity matters more than any single number. Across a reasonable band of discount-rate assumptions, PNR's modeled DCF value ranges from about $40.96 to $89.64 per share. If that range still sits below today's price, the market is optimistic relative to the model across the whole band; if it brackets the price, the stock is roughly fairly valued on our assumptions. Use the interactive slider to see exactly where your own cost-of-capital view lands.

How to read this page: the DCF fair value is what Pentair plc would be worth if its cash flows grow as modeled and are discounted at the stated WACC. The assumptions table shows every input and its source; the reverse-DCF shows what the market believes; the sensitivity band shows how fragile the answer is. None of this is investment advice — it is a transparent, auditable framework for forming your own view of PNR's intrinsic value. Figures update as new filings and prices come in.

Terminal growthESTIMATEAssumption — house default: House default 2.5% (roughly long-run nominal GDP), kept for comparability. Not generous for Pentair: replacement and repair is the majority of pool-equipment demand on a large installed base, and water treatment has a secular tailwind. But it is not conservative either against a company whose revenue was flat from 2023 to 2025. A 2.0% rate takes ~$3.5/share off. Must stay well below the ~9.6% WACC.	2.5%	ESTIMATEAssumption — house default: House default 2.5% (roughly long-run nominal GDP), kept for comparability.
