Belimo’s AI Cooling Demand Fuels a 20% Sales Beat as Guidance Holds Steady

Belimo Holding AG shares fell 5% on Monday even though the Swiss maker of HVAC valves, actuators and sensors beat nearly every first-half estimate on the sheet. Sales hit CHF676 million, up 20.5% from a year earlier and 4% above analyst consensus. Data center customers, racing to keep AI servers from overheating, drove the fastest growth Belimo has logged from any single industry it serves.

Belimo held its full-year targets unchanged anyway. Jefferies now says that stance leaves both the company’s own guidance and the broader analyst consensus positioned for an upgrade.

Sales, Profit and Margin All Clear the Bar

The headline numbers left little room for debate. Revenue of CHF676 million beat the CHF650 million consensus by roughly 4%, and it grew 29.6% in local currency once foreign exchange swings are stripped out. Currency alone cut 9 percentage points off that number as the franc strengthened against the currencies Belimo bills abroad; volume added 22 points and price added 7.

• CHF 676 million in first-half sales, up 20.5% year over year and 4% above analyst consensus.
• CHF 152.5 million in EBIT, up 19% year over year and 7% ahead of consensus.
• 77% growth in sales to data center customers, versus 10% for every other vertical combined.
• CHF 10.15 earnings per share, up 23% year over year.

Earnings before interest and taxes came in at CHF152.5 million, up 19% and about 7% above what analysts expected. The EBIT margin slipped to 22.5% (22.4% stripping out a one-off item) from 22.8% a year earlier, but still cleared the 22% consensus estimate. Jefferies analysts pinned the dip on inventory effects and currency, calling the outcome “much better than initially feared.”

Cash generation lagged the profit line. Operating cash flow fell 10% to CHF84 million, and free cash flow dropped 42% to CHF54 million. Earnings per share still climbed 23% to CHF10.15.

Belimo posts its full semiannual and annual disclosures on a set schedule, and the coming interim filing should show whether that cash flow gap closes.

The Data Center Line Is Growing Four Times Faster

Data center customers bought 77% more from Belimo in the first half than a year earlier, according to Jefferies estimates, versus just 10% growth from every other end market combined. That single vertical is now doing more to move Belimo’s growth rate than the rest of the HVAC business put together.

The demand looks structural, not seasonal. The global market for data center liquid cooling equipment was worth roughly $6 billion in 2026 and is on pace to reach $27.1 billion by 2035, according to Global Market Insights, as AI training racks pack in more power per square foot than air cooling alone can dissipate. Belimo’s control valves and actuators regulate flow inside the chilled-water loops that carry that heat away, a mechanical layer of the AI buildout that rarely comes up on a chip earnings call.

Geography tells the same story. Asia-Pacific revenue jumped 45% (58% in local currency), the fastest of Belimo’s three regions, ahead of the Americas at 22% and EMEA at 11%. Jefferies said EMEA’s slower pace still included an 11% contribution from data centers alongside steady retrofit demand and modest growth in non-residential construction.

Control Valves Carry the Growth

Belimo splits its business into three product lines, and one of them is doing most of the heavy lifting. Control Valves, the company’s largest segment, generated CHF389 million in revenue, up 37% year over year and 48% in local currency. Sensors & Meters grew 30%. Damper Actuators, the oldest and most commoditized line, rose just 1%.

The split lines up with where data centers actually spend. Chilled-water cooling loops lean on control valves to regulate flow to each rack row, which is likely why that segment is absorbing most of the vertical’s growth while damper actuators, tied more to conventional building ventilation, barely moved.

Why Did a Beat Send the Shares Down 5%?

Belimo shares fell because the stock already carried a lot of good news into Monday. Jefferies had cut it to Hold a month earlier on valuation grounds alone, even while raising its price target, and an unchanged guidance range after such a strong quarter reads to some traders as caution rather than confidence.

1. Early June 2026: Belimo shares extend a multi-month rally that pushes the stock toward record levels on the SIX Swiss Exchange.
2. June 22, 2026: Jefferies cuts Belimo to Hold from Buy, lifting its price target to CHF1,035 from CHF1,013, citing a valuation near historic peaks.
3. July 20, 2026: Belimo reports first-half sales of CHF676 million and profit above every estimate; shares fall 5% anyway.

Jefferies made that valuation call while the stock traded at 36 times forward earnings, versus one- and three-year peaks of 41 and 43 times. The brokerage expected most data center volume to already be baked into consensus. “We continue to like the story but don’t see room for further multiple expansion given normalising earnings growth towards low teens going forward,” Jefferies analysts wrote at the time.

That pace, 29.6% in local currency this half, is roughly double the mid-teens growth rate management still guides for the full year and well above the 16% consensus expects. That gap is exactly why Jefferies sees room for both to move higher.

Guidance That Still Has Room to Climb

Belimo kept its full-year target at mid-teens organic growth and a margin above 20%, versus consensus estimates of 16% growth and a 21.6% margin. Management expects growth to slow in the second half as comparisons get tougher and earlier price increases roll off the year-over-year math.

Consensus already bakes in an 11% second-half growth rate and a 20.6% margin. Jefferies analysts called those numbers “very conservative,” a view that lines up with how far the first half ran ahead of both the guidance and the Street’s models.

Belimo’s annual report has landed every February for years, most recently on February 23, 2026. Investors now have until then to see whether the mechanical side of the AI buildout keeps outrunning the guidance built around it.

Frequently Asked Questions

What Does Belimo Actually Make?

Belimo makes actuators, control valves and sensors that regulate heating, ventilation, air conditioning and data center cooling systems. Founded in 1975 and based in Hinwil, Switzerland, the company trades on the SIX Swiss Exchange under the ticker BEAN.

How Big Is the Market for Data Center Cooling Equipment?

Cloud providers are the fastest-growing buyers of that equipment, expanding at a roughly 29.5% compound annual rate as AWS, Microsoft Azure and Google Cloud pour money into AI-ready infrastructure, according to Persistence Market Research’s tracker of cloud cooling spending. Enterprises still hold the largest overall share of the market today.

Is Belimo Stock Still Expensive After the Drop?

Roughly, yes. Before Monday’s decline the stock traded near 36 times forward earnings, according to Jefferies; a 5% drop would put that closer to the mid-30s, still above its own longer-run average and not far below the one-year peak of 41 times. The stock has gotten cheaper, not cheap.
