On October 27, 2026, a company that gets about 30% of its sales from the pool industry had its best trading day in more than six years. Pentair( NYSE:PNR ) rose 12.80% (+$7.07) to $62.29 and then traded at $62.70 after hours, which put its market value at $9.94 billion. This is a water treatment company, even though the name sounds like an under-the-radar airline business.
The stock hadn't posted a larger one-day gain since March 24, 2020, when it jumped about 18% to $27.01 from $22.85. Headlines described Pentair as a company that helps cool AI data centers. The word "AI" does not appear in either the release or the earnings call, though, and Pentair gave no figure for data center revenue.
What Pentair Reported on October 27
Third-quarter sales came in at $976 million, down 4%, and core sales fell 5%. Adjusted EPS was $1.18, down from $1.24 a year earlier. It still beat the $1.07 consensus and Pentair's own guidance of $1.05 to $1.08, with about $8 million of tariff refunds helping.
Pool sales dropped 18% to $291.5 million. Chief executive John Stauch said, "The pool channel inventory realignment is now complete."
That matters because destocking (dealers selling from their shelves instead of reordering) held Pentair's sales below actual pool demand, but with destocking over, orders can rise even if pool demand stays flat.

Where the Data Center Pitch Comes From
The data center angle comes from Taco Group Holdings, a $1.4 billion hydronics deal that closed on October 1. Hydronic systems use pumps, valves, and heat exchangers to move heated or chilled water through a building, and data centers use them too.
Stauch discussed Taco. He said, "increases our exposure to attractive end markets, including HVAC, data centers, and related infrastructure development." He estimated Taco's 2026 sales at about $560 million, up around 23%, and expects 2027 sales above $620 million.
Pentair did not say how much of Taco's business is data centers. All of Taco together is still small next to Pentair's $4.176 billion in 2025 revenue.
Water Solutions sales rose 1% to $421.9 million, but segment income grew 16%. Flow sales rose 4% to $262.5 million, and its income grew 15%.
When income grows that much faster than sales, pricing and cost control are usually the cause. Those gains tend to be more durable than sentiment. Pentair also confirmed its full-year adjusted EPS center of about $4.70.
However, debt can limit the company. Pentair paid for Taco with $1.4 billion of term loans at about 5.25%, so it has less room for buybacks while it pays that debt down. A new finance chief, Bob Hau, starts on November 1.
After the jump, the stock is still about 44% below its 52-week high of $110.90. The stock is also below the $64.33 close it hit after a 15% drop on a guidance cut on July 15, 2026.
What to Watch Next for PNR Stock
The case for Pentair rests on the pool recovery and the margin gains, and until the company reports data center sales, the AI label likely deserves little weight in the valuation.
The $0.27 quarterly dividend, payable on November 6, 2026, gives shareholders income ahead of the 2027 outlook.
For data center exposure that a company actually reports, Vertiv( NYSE:VRT ) offers clearer disclosure. Its second-quarter organic sales rose 18%, and it linked that growth directly to hyperscale data center deployments.
The trigger to check is Pentair's 2027 guidance, due in February. If the stock closes back below $55.22, its pre-jump close, the market will likely have treated this as a relief rally.
