• WTS +2.14%

On August 5, Watts Water Technologies (NYSE:WTS) reported second quarter results showing net sales of $763 million, up 19% on a reported basis and 12% organically compared to the same quarter of 2025. Diluted earnings per share climbed to $3.53, up 17% year over year, while adjusted diluted EPS reached $3.66, up 18%. It was the company's best quarter yet by nearly every top-line measure, and management used the results to raise its full year 2026 outlook. But underneath the headline numbers, profitability told a more complicated story.

Data Centers Carry The Growth

The plumbing, heating and water quality manufacturer leaned hard on one theme this quarter: data centers. Higher volume tied to data center demand showed up across every region Watts operates in, and it was the primary driver behind the 12% organic sales growth for the quarter ended June 28. The Americas segment, by far the company's largest, posted sales of $585 million, up 17% on a reported basis and 12% organically, with acquisitions adding another $28 million. Europe grew sales 12% to $125 million and expanded segment margin by 160 basis points on favorable pricing and productivity gains.

The standout was APMEA, where sales jumped 57% on a reported basis and 31% organically, fueled by data center growth in China, with segment margin up 100 basis points. On the strength of the first half, Watts raised its full-year sales growth outlook to a range of 14% to 17% reported, or 8% to 11% organically, and lifted its adjusted operating margin outlook by 20 to 80 basis points. The company also raised its quarterly dividend to $0.63 per share from $0.52 a year earlier and kept buying back stock, spending $4.1 million to repurchase roughly 13,000 shares during the quarter.

Margins Take A Quiet Hit

For all the top-line momentum, profitability moved the other direction. Operating margin fell 80 basis points to 20.2%, and adjusted operating margin slipped 60 basis points to 21.0%, driven by acquisition dilution, inflation and tariffs, and a difficult comparison against a one-time tariff-related price and cost benefit that boosted results a year earlier. The Americas segment, which carries most of the company's earnings power, saw its margin drop 150 basis points for the same reasons. Restructuring charges also rose, adding further pressure to the operating line.

Free cash flow for the first six months of 2026 fell to $98 million from $105 million a year earlier, as higher accounts receivable, increased inventory tied to tariffs and strategic stockpiling, and higher capital expenditures outweighed the gain in net income. Watts also flagged that its full-year outlook assumes no change in the impact from the Middle East conflict, which has already weighed on the Middle East portion of APMEA sales and added cost headwinds there, and that any future tariff refunds will be treated as a special item rather than folded into adjusted results.

Wall Street's Read On Watts

Hedge fund ownership of Watts climbed to 44 funds in the most recent quarter from 40 previously, which points to institutions building rather than trimming positions. Short interest sits at just 3.93% of the float, a level that suggests little organized skepticism is betting against the stock right now. At the same time, shares trade at a forward P/E of 25.25 as of September 4, a multiple that assumes a good deal of the data center growth story keeps playing out. That combination suggests that the market has largely bought into the growth narrative and left little room for disappointment.

Where The Story Goes Next

Watts delivered its strongest quarter on record and gave investors a raised outlook to go with it, but the margin erosion in its largest segment is worth watching. The bulls have data center demand across three continents and a raised full-year forecast working in their favor. The bears can point to shrinking free cash flow and tariff-driven cost pressure that management itself expects to persist. For the growth story to keep justifying the current multiple, that data center momentum needs to eventually show up in margins rather than just the top line.
