Pentair PNR is a pure-play water company manufacturing a wide range of sustainable water solutions, including energy-efficient swimming pool pumps, filtration solutions, and commercial and industrial pumps. Pentair’s business is organised into three segments: pool, water solutions, and flow. The company benefits from a large installed base of equipment, and over 75% of its products are replacement.

Pentair’s stock has plunged by over 40% year to date amid concerns about the pool business. Although pool faces significant near-term headwinds, we believe that the market is pricing in a worst-case scenario, making shares attractive for investors with a long-term horizon.

Second-quarter pool core sales plummeted by 42% year over year, mostly due to a $170 million channel inventory destocking impact. Management expects channel inventory levels to normalize by the end of the third quarter, positioning pool to return to growth in 2027. We expect pool to return to normalised growth in the midsingle digits once channel inventory levels normalise.

We believe the market is missing Pentair’s long-term growth runway. When the housing outlook improves, we expect growing housing starts to translate into higher new pool construction as well as higher adoption of pool automation, significantly increasing the dollar content per pool pad.

Business strategy and outlook

In 2022, Pentair acquired Manitowoc Ice from Welbilt for roughly $1.6 billion. Manitowoc Ice is a leading producer of commercial ice makers, with roughly 50% market share of cubed ice machines sold in the US. From a strategic perspective, we believe that the acquisition will complement Pentair’s existing commercial water solutions portfolio and bolster its presence in the foodservice industry.

Pool has faced significant headwinds in 2026 due to the inventory correction in the channel as well as some aftermarket share losses on older pool pads, but we forecast the segment to return to a more normalized revenue growth rate in 2027 and beyond as we expect it to capitalize on opportunities in pool automation.

In the long run, we expect Pentair to increase revenue at a mid-single-digit clip, fueled by opportunities in pool and water solutions. Furthermore, we are encouraged by Pentair’s margin expansion since the Manitowoc Ice acquisition. Management’s long-term targets include delivering mid-single-digit revenue growth and roughly 300-basis-point operating margin expansion from 2025 levels by 2028.

Bulls say

  • Pentair is a pure-play water company poised to benefit from demand for sustainable and energy-efficient water solutions.
  • The pool business continues to deliver solid revenue growth, consistent market share gains, and lucrative operating margins.
  • Pentair’s transformation initiatives have continued to drive strong margin expansion in recent years.

Bears say

  • Growth has been relatively sluggish and may remain elusive in the flow segment.
  • Persistent strength in the US dollar could make Pentair more susceptible to offshore competition.
  • Cost inflation could be a headwind in the short run.

Star Rating: Our one- to five-star ratings are guideposts to a broad audience and individuals must consider their own specific investment goals, risk tolerance, and several other factors. A five-star rating means our analysts think the current market price likely represents an excessively pessimistic outlook and that beyond fair risk-adjusted returns are likely over a long timeframe. A one-star rating means our analysts think the market is pricing in an excessively optimistic outlook, limiting upside potential and leaving the investor exposed to capital loss.

Fair Value: Morningstar’s Fair Value estimate results from a detailed projection of a company’s future cash flows, resulting from our analysts’ independent primary research. Price To Fair Value measures the current market price against estimated Fair Value. If a company’s stock trades at $100 and our analysts believe it is worth $200, the price to fair value ratio would be 0.5. A Price to Fair Value over 1 suggests the share is overvalued.

Moat Rating: An economic moat is a structural feature that allows a firm to sustain excess profits over a long period. Companies with a narrow moat are those we believe are more likely than not to sustain excess returns for at least a decade. For wide-moat companies, we have high confidence that excess returns will persist for 10 years and are likely to persist at least 20 years. To learn more about how to identify companies with an economic moat, read this article by Mark LaMonica.

Uncertainty Rating: Morningstar’s Uncertainty Rating is designed to capture the range of potential outcomes for a company. An investor can think of this as the underlying risk of the business. For higher risk businesses with wider ranges of potential outcomes an investor should consider a larger margin of safety or difference between the estimate of what a share is worth and how much an investor pays. This rating is used to assign the margin of safety required before investing, which in turn explicitly drives our stock star rating system. The Uncertainty Rating is aimed at identifying the confidence we should have in assigning a fair value estimate for a stock. Read more about business risk and margin of safety here.
