Summary

• SLB has agreed to buy thermal-management specialist Kelvion in a transaction worth about $4.1bn including assumed debt.
• Kelvion expects data centres to provide more than half of its 2026 revenue as AI systems drive higher thermal loads.
• Cooling is becoming a strategic infrastructure market as spending on AI spreads into engineering, power, construction, and industrial equipment.

SLB has agreed to buy thermal-management specialist Kelvion in a transaction worth about $4.1 billion including assumed debt, giving the energy-technology group a much larger position in the cooling systems required around increasingly dense AI computing infrastructure.

SLB will pay approximately $3.4 billion in cash and assume around $700 million of debt. The transaction is subject to regulatory approvals and other closing conditions and is expected to complete during the first half of 2027.

Kelvion already earns a substantial portion of its revenue from data centres. SLB expects the company to generate between $2.3 billion and $2.4 billion during 2026, with data-centre customers contributing between $1.2 billion and $1.3 billion as the largest and fastest-growing part of the business.

Those numbers put a valuation on an engineering layer that used to sit well behind processors and servers in discussions about computing infrastructure. Higher-density AI systems produce more heat inside each rack, forcing operators to rethink how cooling is designed, installed, maintained, and integrated with electrical systems.

Cooling moves from support system to deal thesis

Liquid cooling is becoming more common in high-performance installations because conventional air cooling becomes harder to use as thermal loads rise. That shift has consequences throughout a data centre, from pipes and heat exchangers to pumps, facility design, redundancy, maintenance, and the power required to operate the cooling system itself.

Techopia examined those pressures in AI cooling becomes a fluid problem, where infrastructure suppliers were already adapting products around hotter computing hardware. Kelvion gives SLB an established portfolio of heat-exchange technology at the point when that specialist engineering is moving deeper into mainstream data-centre design.

SLB itself has entered the market from outside conventional enterprise technology. Its historical expertise lies in energy, engineering, complex industrial systems, and large physical projects, but the company has been building a Data Center Solutions operation spanning modular infrastructure, offsite manufacturing, engineering, and related services.

The acquisition broadens that strategy from building facilities towards supplying technology inside their thermal systems. SLB expects its existing data-centre operation and Kelvion together to generate more than $2 billion of data-centre revenue and around $300 million of adjusted EBITDA on a pro-forma basis in 2026.

AI spending spreads through industrial supply chains

The deal illustrates how the AI investment cycle is moving into sectors that would not normally be categorised as software or semiconductor businesses. Electrical-equipment manufacturers, cooling companies, engineering contractors, utilities, property developers, and construction specialists are increasingly exposed to decisions made by cloud groups and AI infrastructure operators.

That creates opportunities for industrial suppliers while tying part of their growth to a market whose future buildout remains uncertain. Announced data-centre capacity can be delayed by grid connections, planning, financing, equipment shortages, customer demand, and changes in the economics of AI workloads long before completed buildings start generating revenue.

SLB is nevertheless attaching ambitious growth targets to the combination. It wants the enlarged data-centre business to produce between $4.5 billion and $5 billion of revenue and $700 million to $800 million of adjusted EBITDA during 2028, while expecting approximately $120 million of annual EBITDA synergies within three years.

The transaction value reflects those expectations. SLB estimates the price at roughly 11 times Kelvion’s forecast 2026 EBITDA before synergies and around 8.5 times once anticipated savings and additional revenue are included.

Kelvion also operates outside computing, supplying thermal-management technology to energy and industrial customers. That diversification reduces dependence on a single infrastructure cycle, although data centres provide much of the immediate growth rationale for SLB’s acquisition.

Integration will now determine whether the engineering logic produces the financial returns built into the purchase price. SLB has to combine a large acquired industrial business with its developing data-centre operation while customers themselves are adapting to new generations of accelerators, cooling architectures, and facility designs.

Even before the deal closes, however, it demonstrates where part of the value created by AI infrastructure is migrating. The competitive bottleneck is no longer confined to obtaining chips; getting heat away from those chips reliably enough to keep them running has become valuable enough to support a multibillion-dollar acquisition.
