SLB agreed Monday to acquire Kelvion from Apollo Global Management for $3.4 billion in cash, not including debt. The thermal management provider—German-domiciled, 3,500 employees across 60 locations—generates approximately $1.2 billion in annual revenue from heat exchangers, cooling towers, and liquid-to-air systems. Apollo bought Kelvion in 2015 for roughly $750 million through a syndicate including Triton Partners, marking a 4.5x gross return before debt adjustments.
SLB's statement positions the deal as "expanding its role across data center infrastructure," language that signals permanent allocation shift rather than cyclical bet. The company entered data center cooling in 2023 through its Neothermal and ChampionX integration, which combined generated $340 million in thermal revenue last year. Kelvion adds $1.2 billion immediately, creating a $1.5 billion thermal platform before cross-sell. SLB's total 2025 revenue was $33.1 billion, meaning this acquisition moves data center exposure from 1% to roughly 4.5% of consolidated sales in a single stroke.
The timing reflects three converging forces. First, hyperscale and AI data center buildout now requires 15-25 megawatts per facility versus 5-8 megawatts in legacy enterprise hosting, with cooling accounting for 40% of total capital expenditure in liquid-cooled GPU clusters. Second, oilfield services margin compression continues—SLB's Q4 2025 EBITDA margin was 21.3%, down 180 basis points year-over-year despite flat rig counts. Third, Apollo is rotating private equity capital out of industrials and into credit strategies; the firm raised $45 billion for its opportunistic credit fund in Q1 2026 and has sold $8.2 billion in portfolio companies this year, most into strategic hands.
Kelvion's customer base includes BMW, BASF, and Dow Chemical—process industries with mature contracts and predictable replacement cycles. SLB gains immediate access to 12 hyperscalers through Kelvion's existing data center segment, which grew 47% in 2025 and now represents 18% of Kelvion's revenue. The acquisition also brings 230 thermal engineers, a talent base SLB cannot hire at speed in a market where liquid cooling specialists command $240,000-$320,000 total compensation in the U.S. and Germany.
Operators should track three items. SLB's investor call is scheduled for September 9, where management will detail expected $150-$200 million in cost synergies and outline the integration of Kelvion's European manufacturing into SLB's subsea and surface equipment supply chain. Second, watch for SLB's revised 2027 guidance in the thermal segment; consensus currently models $420 million excluding this deal, and the reset will indicate whether SLB views data center as 15% or 25% of total revenue by 2030. Third, Apollo's remaining energy exposure—particularly its $1.8 billion stake in Williams Companies and minority position in Venture Global LNG—may come to market if the firm continues de-risking commodity-linked assets.
The deal closes Q4 2026 subject to German and U.S. antitrust clearance. SLB will fund the purchase through $2.1 billion in cash and $1.3 billion in new term debt, raising net leverage from 0.6x to approximately 1.1x EBITDA. The company has $4.7 billion in undrawn revolver capacity and generated $5.3 billion in free cash flow over the trailing twelve months, leaving the balance sheet unextended even if oil prices soften below $70 Brent through year-end.
The takeaway
SLB shifts $3.4 billion into thermal infrastructure, moving data center exposure to 4.5% of revenue and validating cooling as the new energy services margin pool.

Your next customer won't visit your website. Their AI will.
AI assistants have quietly taken over the first step of buying — they answer from catalogs they can read and shortlist whoever can actually ship. Two questions now decide whether you exist to that buyer: can a machine read your catalog, and can you fulfill the order. Most brands fail one or both and never find out why the orders went elsewhere. The winners of this shift aren't the loudest. They're the most readable. Build for the machine that's about to do the shopping.
