Pentair plc (PNR) Earnings: Q3 2026 Results

The quarter ended September 30, 2026 and Pentair published the results on October 27, 2026. Revenue and diluted EPS are shown against Q3 2025, the same quarter a year earlier, which takes seasonal swings out of the comparison. Pentair reports EPS two ways: GAAP, under the accounting rules every US filer follows, and adjusted, which leaves out items the company considers outside its operating results. The release reconciles the two, and when they diverge, the reconciliation says why.

• Effective January 1, 2026, Pentair moved its legacy residential and irrigation flow business from the Flow segment into Water Solutions and recast prior periods, so the year-ago segment figures here differ from those in the Q3 2025 release. Total net sales are unchanged.
• EPS figures are from continuing operations. Pentair's Q3 2026 results include approximately $8 million of IEEPA tariff refunds.
• Pentair acquired Taco Group Holdings on October 1, 2026, after the quarter ended, for $1.425 billion. Its sales start in Q4 2026.

How Pentair splits revenue in its own release, under its own labels, for Q3 2026 against Q3 2025. Indented lines are parts of the line above them.

• Pentair's Flow revenue was $263 million in Q3 2026, up 4% from $251 million in Q3 2025, 27% of total revenue.
• Pentair's Water Solutions revenue was $422 million in Q3 2026, up 1% from $416 million in Q3 2025, 43% of total revenue.
• Pentair's Pool revenue was $292 million in Q3 2026, down 18% from $354 million in Q3 2025, 30% of total revenue.
• Pentair's Corporate and other revenue was $0.5 million in Q3 2026, up 25% from $0.4 million in Q3 2025, under 1% of total revenue.

Segment lines are the figures writers cite most often, because they show where the growth in a quarter came from. Companies redraw their segments from time to time and restate the prior year to match, so a year-ago figure here can differ from the one printed a year ago. When that has happened, the note above says so.

From the earnings release

• Q3 2026 (this page), reported Oct 27, 2026

Pentair's net sales were $976.4 million in Q3 2026, down 4 percent from $1,022.0 million, and core sales, which exclude currency, acquisitions and divestitures, fell 5 percent. Pentair reports three segments: Water Solutions was the largest at $421.9 million, Pool brought in $291.5 million and Flow $262.5 million. (Pentair Q3 2026 release, Oct 27, 2026)

Pool drove the decline. Pool sales fell 18 percent to $291.5 million from $354.3 million, which Pentair said reflected the completion of an inventory realignment with its major channel partners. Its 10-Q says the destocking was more pronounced than previously estimated, that business conditions worsened with higher interest rates and inflation, and that the destocking was complete as of September 30, 2026. Channel exposure is concentrated: Pentair's largest customer represented approximately 18% of consolidated net sales in 2025, and no other customer exceeded 10%. (Pentair Q3 2026 release, Oct 27, 2026; Pentair Form 10-Q, Q3 2026, Oct 27, 2026; Pentair Form 10-K, 2025, Feb 24, 2026)

Across Pentair, volume subtracted 9.0% from sales and price added 3.5%. Flow sales rose 4 percent, with 1 percent core growth and the rest mainly from the Hydra-Stop acquisition completed in Q3 2025. Water Solutions sales rose 1 percent. By vertical, residential sales fell to $483.3 million from $568.3 million, while commercial rose to $295.2 million from $257.6 million and industrial was $197.9 million. (Pentair Form 10-Q, Q3 2026, Oct 27, 2026; Pentair Q3 2026 release, Oct 27, 2026)

The U.S. accounted for $676.9 million of Pentair's Q3 2026 net sales, Western Europe $116.8 million, developing markets (primarily China, Latin America, the Middle East and Southeast Asia) $117.5 million and other developed markets $65.2 million. On October 1, 2026 Pentair bought Taco Group Holdings, a maker of hydronic and water-driven products for the HVAC, plumbing and industrial sectors, for $1.425 billion; it joins the Water Solutions segment. (Pentair Form 10-Q, Q3 2026, Oct 27, 2026)

Pentair's diluted EPS from continuing operations was $0.91 in Q3 2026, against $1.12, and its adjusted EPS was $1.18, against $1.24. The $0.27 gap comes from adjustments Pentair excludes: $11.4 million of restructuring and other costs, $16.1 million of transformation costs, $15.1 million of intangible amortization, $3.4 million of deal-related costs and $4.9 million of bridge financing fees for the Taco deal, less related income tax adjustments. (Pentair Q3 2026 release, Oct 27, 2026)

Operating income fell 15 percent to $195.9 million, a return on sales of 20.1%. Adjusted operating income was $242 million, with adjusted return on sales of 24.8 percent. Segment margins moved apart: Pool's return on sales fell 820 basis points to 24.6%, while Water Solutions rose 370 basis points to 28.7% and Flow 250 basis points to 26.2%. Results include approximately $8 million of IEEPA tariff refunds. (Pentair Q3 2026 release, Oct 27, 2026)

Net interest expense rose to $21.7 million from $14.4 million and the effective tax rate was 16.3%, against 15.0%. Diluted shares fell to 160.3 million from 165.1 million: Pentair repurchased 4.0 million shares for $350.0 million in the first nine months of 2026 and had $650.0 million left under its authorization. The quarterly dividend rose to $0.27 per share from $0.25, the 50th consecutive year Pentair has raised it. (Pentair Q3 2026 release, Oct 27, 2026; Pentair Form 10-Q, Q3 2026, Oct 27, 2026)

Diluted EPS divides net income by the weighted average number of shares outstanding in the quarter, plus the shares that options and other equity awards could add. Buybacks shrink that count and lift EPS for the same profit; share issuance and stock awards enlarge it.

Pentair gives quarterly and full-year EPS and sales guidance in its release. It now expects full-year 2026 GAAP EPS from continuing operations of approximately $3.76 and adjusted EPS of approximately $4.70, the midpoint of its previous range, with sales down approximately 3 percent on a reported basis. That guidance includes the right-sizing of pool channel inventory and the Taco acquisition. (Pentair Q3 2026 release, Oct 27, 2026)

For Q4 2026 Pentair guided GAAP EPS of approximately $1.07, adjusted EPS of approximately $1.15, and reported sales up approximately 7 percent to 9 percent from Q4 2025, when it reported net sales of $1,020.5 million and adjusted EPS of $1.18. (Pentair Q3 2026 release, Oct 27, 2026)

A consensus figure is the average of the models published by the analysts who cover Pentair, collected by a data provider and revised up to the day of the report. A quarter that lands above it says how expectations were set as much as how the business did, and the share price on the day also reflects the guidance and the lines no consensus covers.

The consensus figures on this page are Yahoo Finance's, as pulled on the date shown. Each comes with the number of analysts behind it; the smaller that number, the more one revised estimate can move the average.

The figures below are the ones Pentair's own release and filings put weight on for Q3 2026, with the latest reported value for each.

What the quarter means for a holding is a separate question from what it reported. The case for and against owning PNR is on is PNR a buy or a sell?, what analysts expect next is on the PNR forecast, and what the company does is on the Pentair plc (PNR) stock page.

Every number on this page can be traced to a document Pentair published. Checking one takes a couple of minutes, and it is worth doing before you quote a figure anywhere.

• The results release is the document linked in the source line above. Companies publish it on their investor relations site at the moment results go out, and it carries the headline tables: revenue, operating income, net income and EPS for the quarter and the year-ago quarter.
• The same release is filed with the SEC as Exhibit 99.1 to a Form 8-K under Item 2.02, usually on the day of the report. The SEC copy does not change after the fact, which makes it the safer thing to link when you cite a number.
• The quarterly report (Form 10-Q) follows within a few weeks and carries the full financial statements, the segment note and management's discussion of what changed. The fourth quarter is covered by the annual report (Form 10-K) instead.
• Restated comparisons are flagged in the notes on this page. When a company redraws its segments or changes how it adjusts EPS, it restates the year-ago column, so the year-ago figure in a new release can differ from the one printed a year ago. This page always uses the comparison in the newer release, because that is the like-for-like one.
