Fair Value models

Price $72.03 · Downside -14.0%
Model ⓘEach model values the company its own way (discounted cash flow, earnings, assets, dividends). The fair value above starts from their evidence-weighted blend, not from a single model. In cyclical trough or peak years, after dilution or a stock split it is adjusted afterwards, so it can sit above or below the models. Based on fiscal year 2025 figures (about 10 months old). Earnings retained since then ($2.28 per share) are deliberately not added.Bear ⓘBear = the cautious scenario: the same model computed with conservative anchors (lower growth, margins and valuation multiples). Together with Bull it frames a plausible valuation range, not a price target.BaseBull ⓘBull = the optimistic scenario: the same model computed with favourable anchors (higher growth, margins and valuation multiples). Together with Bear it frames a plausible valuation range, not a price target. If a model's bull case is above four times its base value, the table shows that limit with a > sign (like the overall Bull above): beyond it no assumption holds.Coverage ⓘCoverage = how well-backed THIS model's estimate is for this stock (0–100): how complete and reliable its input data are, and how well the model fits the company. The final Fair Value is an evidence-weighted blend, so better-evidenced models count more. Green ≥70, amber 50–69, grey below 50.

Growth Quality ⓘGrowth is valuable only when reinvestment earns attractive returns (Aswath Damodaran): sustainable growth depends on return on capital, reinvestment and efficiency.

What shareholders gained per year (last 5 years) ⓘWhat the business itself delivers per year: earnings growth per share plus the dividend yield. This is what you get IF the market keeps valuing the stock the same way: it contains no assumption about the market changing its mind. Computed per share, so buybacks count and a merger does not pass as growth. For a company that pays no dividend it is pure earnings growth per share. Period: earnings growth per share as CAGR over the last 5 reported fiscal years (annual statements), plus the current dividend yield. The start value is the median of the three years around the start, so a single crisis year (a pandemic or a write-down) does not distort the rate.

Growth Forecast
Little optimism in the price
The price assumes about as much growth as the company has delivered so far and less than analysts expect.
What the price assumes ⓘThis turns our valuation around: instead of asking what the share is worth, it asks what growth the current price requires. It uses the cash the company keeps after all spending (free cash flow), the same discount rate as our models, five years of growth, then slowing evenly to 2 % a year by year ten. Compared with the analysts' sales forecasts extended to the same five years (at least three analysts, for context only, it does not enter the Fair Value): within 3 percentage points counts as "in line" (amber), below that little optimism (green), above that a lot of optimism (red).
+6.3%
Yearly growth needed for the next five years to justify today's price.
What forecasts expect ⓘAnalysts publish sales forecasts for the next two fiscal years. For the years after that, growth slows evenly to 2 % a year by year ten (2 % is the long-run rate our models use). Projected years are marked as such.
+11.4%
Yearly sales growth analysts expect, extended to five years.
After inflation (USA: IMF forecast 2.4% a year to 2030, 3.1% from 2016 to 2025) that is about +3.9% a year for the price and +8.8% for the forecasts.
News mood ⓘNews mood, the average tone of recent news (95 articles), rated against how stocks are usually covered. 🚀 Hype = unusually upbeat · 🙂 Positive = above average · 😐 Neutral = typical · 🙁 Negative = below average · 😨 Very negative = unusually downbeat. It reflects the tone of coverage, not our valuation.Neutral
Recent news coverage is roughly neutral, about typical for how stocks are covered.
AI conclusion: The expanded portfolio via the Taco acquisition strengthens exposure to hydronic systems and data centers, yet thin public evidence limits confirmation of any durable advantage.
Main risk: Named competitors such as Xylem in industrial water systems and Hayward or Fluidra in pool equipment could capture market share or force price reductions in Pentair's key pool and flow segments.
Bull case: Pentair could leverage the Taco acquisition and data-center cooling demand to expand cross-selling in commercial hydronics while using efficiency innovations to differentiate from rivals and reduce debt through strong cash generation.
Bear case: Persistent competition from Xylem, Hayward and Fluidra combined with integration challenges and higher leverage could erode margins in pool and water segments and limit Pentair's ability to invest or deleverage effectively.
Pentair closed its acquisition of Taco Group Holdings on October 1, broadening exposure to hydronic systems and data center infrastructure beyond its traditional pool focus. With channel destocking now complete, the pool segment could stabilize, but the company must still navigate softer demand there while integrating the new business. Our models see it as overvalued. Will the expanded portfolio drive more growth than the pool recovery can deliver on its own?

What is a reverse DCF?
A reverse DCF turns the usual calculation around. Instead of deriving a value from assumptions, it takes today's price as given and asks: what free-cash-flow growth would a company have to deliver for exactly this price to be fair? The result is not a forecast but the expectation already priced in. For Pentair PLC that is +6.3 % per year a year over ten years, using the same discount rate (9.3 %) and the same formula as our fair value.
