SLB agreed to acquire Kelvion, a German thermal management company, for $4.1 billion in cash. The transaction moves the oilfield services company—formerly Schlumberger—into industrial-scale cooling systems as hyperscalers push data center capacity past existing thermal limits. Kelvion manufactures heat exchangers and cooling towers for industrial clients. SLB will repurpose that capability for rack-level thermal management.
The acquisition completes SLB's pivot toward infrastructure that began with its $430 million purchase of Aker Carbon Capture in 2022 and its $2.4 billion formation of the Nebula joint venture with Aker and Doosan in 2023. Kelvion adds 3,800 employees and manufacturing footprint across 17 countries. SLB expects the deal to close in Q3 2025 after regulatory clearance in Germany and the EU. The company will integrate Kelvion's liquid cooling patents with its own subsea pressure management systems, which already handle thermal loads in deepwater drilling operations at depths exceeding 10,000 feet.
This matters because energy companies are repositioning balance sheets around power infrastructure faster than most allocators anticipated. SLB's capex toward non-hydrocarbon revenue streams now exceeds $6 billion over two years. The company disclosed in its Q4 2024 earnings that data center and industrial transition projects represented 9% of total revenue, up from 3% in 2022. Kelvion's order book includes contracts with European hyperscalers and pharmaceutical manufacturers, which SLB can leverage through its existing relationships with Middle Eastern sovereign wealth funds building greenfield data center capacity in Saudi Arabia and the UAE. The thermal management market for AI-optimized data centers is projected to reach $12 billion by 2027, with liquid cooling systems—Kelvion's core product—capturing 38% of new installations as rack power density exceeds 40 kilowatts per unit.
The deal also signals that traditional energy companies view AI infrastructure as a hedge against demand volatility in hydrocarbons. SLB's reserve replacement ratio has declined from 112% in 2019 to 87% in 2024, and the company has shifted $18 billion in assets toward services that benefit from electrification and digitalization. Kelvion's EBITDA margin of 14% is lower than SLB's core drilling margin of 22%, but the cooling business carries no commodity price exposure and operates on multi-year service agreements with contractual escalators tied to installation growth rather than oil benchmarks.
Operators and allocators should monitor SLB's ability to cross-sell Kelvion's thermal systems into its existing Middle Eastern contracts, particularly the $3.2 billion Saudi Aramco digitalization program announced in late 2024. Watch for integration updates in SLB's Q2 2025 earnings, expected in late July. The company has not disclosed whether it will retain Kelvion's pharmaceutical and chemical cooling contracts or divest them to focus exclusively on data center capacity. Regulatory filings in Germany are due by mid-May, and any competition concerns from the European Commission would surface by early June.
SLB's pre-announcement stock price was $42.18. The company is funding the acquisition with cash on hand and a $1.8 billion credit facility arranged through JPMorgan and BNP Paribas. Kelvion's revenue for 2024 was $1.1 billion, implying SLB paid 3.7x sales for a business that serves the fastest-growing segment of industrial infrastructure.
