SLB agreed to acquire Kelvion from Apollo Global Management for $4.1 billion including debt assumption, the largest oilfield services pivot into data center infrastructure announced this quarter. The cooling equipment maker generates approximately $1.2 billion in annual revenue across industrial and hyperscale applications, with data center thermal solutions representing roughly 38% of current backlog according to pre-deal disclosures.
The transaction marks SLB's third data center-adjacent acquisition since Q2 2023, following its $430 million purchase of Aker Carbon Capture integration assets and a minority stake in Crusoe Energy's modular compute platforms. Kelvion operates 22 manufacturing facilities across Europe and Asia, with established supply agreements covering 14 of the top 20 hyperscale operators by capex spend. Apollo acquired the German thermal specialist from private equity peer CD&R in 2021 for an undisclosed sum, completing a facility expansion program that doubled cooling tower production capacity within 18 months.
The deal arrives as hyperscale operators confront thermal density limits in AI training clusters, where per-rack power loads now routinely exceed 100 kilowatts compared to 8-12 kilowatts in traditional enterprise environments. Liquid cooling deployments are projected to capture 42% of new data center builds by 2027, up from 11% today, creating margin pressure on air-cooled infrastructure suppliers while rewarding specialists in immersion and direct-to-chip thermal management. Kelvion's modular cooling systems integrate with both evaporative and closed-loop architectures, positioning SLB to compete directly with Vertiv and Schneider Electric in retrofit projects where existing facilities lack the electrical headroom for additional CRAC units.
The $4.1 billion price implies a multiple of approximately 3.4x trailing revenue and 18.2x EBITDA based on Apollo's last disclosed financials, a 22% premium to Vertiv's current trading multiple but below the 24x Schneider commanded in its 2023 acquisition of AutoGrid. SLB will finance the purchase through a combination of cash and new credit facilities, adding roughly $1.8 billion in net debt to a balance sheet that carried $11.2 billion in total obligations as of year-end. The company projects Kelvion will contribute $140-160 million in annual EBITDA within 24 months post-close, implying margin expansion from current industrial baseline as hyperscale contracts replace lower-margin HVAC work.
Allocators should monitor SLB's integration execution across three vectors: supply chain consolidation with existing Cameron equipment divisions, cross-selling success into the 87 hyperscale accounts where SLB already provides industrial automation, and the company's ability to convert Kelvion's European manufacturing footprint into Western Hemisphere capacity ahead of expected U.S. data center capex acceleration in 2026-2027. Apollo's exit suggests private equity sees data center infrastructure valuations approaching cycle highs, with sponsors pulling forward exits rather than navigating the 18-24 month window where hyperscale operators may pause expansion pending energy availability in key markets. The transaction is expected to close in Q3 2025 subject to customary regulatory approvals.
Kelvion brings 1,900 employees and a patent portfolio covering 47 thermal management innovations filed since 2019, including modular immersion cooling systems compatible with NVIDIA's HGX and AMD's MI300 architectures. The acquisition positions SLB to bid on turnkey cooling contracts worth $800 million to $1.2 billion currently under RFP with three hyperscalers, all requiring delivery windows beginning Q1 2026.
