Pentair (PNR) is under pressure after a sharp earnings warning tied to its Pool segment, a cut to second quarter and full year 2026 guidance, and the abrupt departure of its recently appointed CFO.

The sharp guidance cut and CFO change have come on top of an already weak run for Pentair, with the share price down 37.7% year to date and the 1 year total shareholder return also declining 37.8%. However, the 3 and 5 year total shareholder returns are slightly positive.

After a single day drop that wiped nearly a fifth off Pentair’s market value, the stock now trades at roughly a 29% discount to analyst targets and about a 32% gap to intrinsic estimates. Is the market’s caution overdone, or fair?

Most Popular Narrative: 35.1% Undervalued

With Pentair last closing at $65.69 against a widely followed fair value estimate of $101.17, the gap between price and narrative is wide and very clear.

Pentair is expected to benefit from growing momentum in longer-cycle infrastructure and industrial water projects, supported by accelerating municipal and industrial investments in water reuse, filtration, and flow solutions; this should drive more resilient multi-year revenue growth beyond near-term residential softness.

Want to see how a steady growth path, rising margins, and a higher future earnings multiple all combine into that fair value? The narrative spells out the revenue glide path, profit lift, and valuation reset that need to line up for Pentair to justify that price tag. Curious which assumptions really carry the model and which just fine tune it? The full story joins those dots.

Result: Fair Value of $101.17 (UNDERVALUED)

However, Pentair’s residential exposure and reliance on recent price increases could still pressure volumes and margins if housing activity stays weak or competitors push back on pricing.
