SLB bets $4.1bn on Kelvion as data-center cooling becomes a new growth engine

SLB Limited is making one of its clearest moves yet beyond traditional oilfield services, agreeing to acquire thermal-management specialist Kelvion in a transaction valued at approximately $4.1 billion as artificial intelligence drives unprecedented investment in data-center infrastructure. SLB will pay approximately $3.4 billion in cash and assume around $700 million of Kelvion debt, acquiring the company from Apollo-managed funds and minority owner Triton. Kelvion is expected to generate between $2.3 billion and $2.4 billion of revenue in 2026, including as much as $1.3 billion from data centers, its largest and fastest-growing market. The acquisition could therefore give SLB immediate scale in a market where cooling, power management and infrastructure efficiency are becoming critical constraints on AI expansion. Investors responded positively, pushing SLB shares sharply higher on August 31 as the market increasingly viewed the deal as a diversification opportunity rather than simply another industrial acquisition.

The transaction also provides unusually clear financial targets. SLB expects Kelvion to generate adjusted EBITDA of approximately $350 million to $400 million this year and values the acquisition at roughly 11 times expected 2026 EBITDA before synergies. Including the anticipated benefits from integration, the multiple falls to around 8.5 times EBITDA, while management expects the acquisition to increase both earnings per share and free cash flow per share during the first 12 months after closing.

SLB’s $4.1 billion Kelvion acquisition dramatically expands its exposure to AI infrastructure

The strategic centerpiece of the transaction is Kelvion’s position in thermal management. Data centers require enormous amounts of electricity, but converting that power into computing capacity also generates substantial heat, making cooling infrastructure increasingly important as artificial intelligence workloads increase rack density and overall thermal loads.

Kelvion has more than a century of experience developing heat-exchange and thermal-management technologies for industrial and energy applications. Its portfolio includes technologies used for heat rejection, air cooling, liquid cooling and other thermal systems required across data centers and complex industrial operations.

The company’s exposure to data centers has expanded rapidly under Apollo-managed funds. Data-center revenue is expected to reach between $1.2 billion and $1.3 billion during 2026, representing more than half of Kelvion’s anticipated total revenue and establishing the segment as its largest and fastest-growing end market.

That growth explains why SLB is willing to commit billions of dollars to a business outside its traditional oilfield-services identity. Chief Executive Officer Olivier Le Peuch indicated that management views artificial intelligence as driving an exceptionally large infrastructure investment cycle and believes Kelvion can accelerate SLB’s transformation into a broader industrial technology supplier for data-center customers.

The combination is expected to more than double the revenue opportunity available to SLB for every gigawatt of data-center capacity delivered. By combining Kelvion’s thermal-management technology with SLB’s engineering, modular manufacturing, offsite construction and digital capabilities, the company intends to offer customers a larger share of the infrastructure required to build and operate high-density computing facilities.

That approach reflects a wider shift occurring across industrial companies as data-center operators seek suppliers capable of addressing multiple infrastructure constraints simultaneously. Access to computing chips remains crucial, but access to electricity, cooling equipment, grid connections and reliable construction capacity increasingly determines how quickly new AI infrastructure can actually become operational.

Kelvion could help SLB build a data-center business approaching $5 billion of annual revenue

SLB has provided aggressive growth targets for the combined operation, giving investors a clearer benchmark for evaluating whether the acquisition creates sufficient value. SLB and Kelvion are expected to generate more than $2 billion of combined pro forma data-center revenue during 2026, with approximately $300 million of adjusted EBITDA. By 2028, SLB is targeting between $4.5 billion and $5 billion of annual revenue from its combined data-center solutions business and adjusted EBITDA of between $700 million and $800 million.

Reaching those targets would mean more than doubling data-center revenue over roughly two years, placing the business among SLB’s more significant growth platforms. It would also reduce the company’s dependence on upstream oil and gas spending, which remains exposed to commodity prices, producer capital budgets and regional drilling cycles.

Reuters reported that SLB is pursuing the expansion partly as traditional drilling-service demand moderates, making data-center infrastructure an increasingly important diversification opportunity. The acquisition does not represent an exit from oil and gas, but it broadens the company’s addressable market into infrastructure benefiting from AI-related capital expenditure rather than primarily hydrocarbon production.

The financial rationale also relies on integration benefits. SLB expects approximately $120 million of annual EBITDA synergies within three years of completing the acquisition, generated through a combination of cost efficiencies and incremental revenue opportunities.

Those revenue synergies could be particularly important because SLB already has capabilities in modular infrastructure and engineering that can potentially be combined with Kelvion’s cooling technologies. Rather than selling standalone components, the combined group could pursue larger integrated contracts and capture more revenue from each data-center development.

Management expects the transaction to close during the first half of 2027, subject to regulatory approvals and customary conditions. The timing gives SLB several quarters to prepare integration plans while data-center operators continue increasing spending on power-intensive AI infrastructure.

Kelvion adds energy-transition and industrial exposure beyond the data-center cooling market

Although data centers dominate the investment narrative, Kelvion also provides SLB with exposure to several markets closely related to its existing energy-transition strategy. Kelvion supplies thermal-management technologies used in heat pumps, renewable energy projects, carbon capture systems and industrial processing. These applications depend on many of the same engineering principles required for data-center cooling, creating potential overlap with SLB’s existing efforts to expand into lower-carbon energy technologies.

That diversification could prove useful if data-center infrastructure spending eventually moderates. Kelvion would not leave SLB dependent on a single AI-related customer base because its equipment is also used across traditional energy and industrial markets where efficiency and heat management remain essential.

Apollo’s relatively short ownership period also highlights how quickly Kelvion’s strategic positioning has changed. Apollo-managed funds agreed to acquire a majority interest in Kelvion from Triton in August 2025, while Triton retained a minority stake. Apollo subsequently increased the company’s investment and strategic focus on data centers before agreeing to sell the entire business to SLB roughly a year later.

The sale therefore demonstrates how rapidly private-equity and strategic buyers are assigning greater value to businesses positioned around AI infrastructure. Cooling equipment may once have been viewed primarily as conventional industrial machinery, but rising computing density has transformed thermal management into a critical component of data-center economics.

For SLB, the transaction also extends a broader strategy already visible before the Kelvion announcement. In July, the company announced a strategic alliance with Liberty Energy focused on data-center infrastructure and power solutions, indicating that management had already identified the sector as a priority growth market. Kelvion significantly accelerates that strategy by bringing an established revenue base, manufacturing footprint, engineering workforce and customer relationships into SLB rather than requiring the company to build an equivalent thermal-management operation organically.

SLB stock rally suggests investors support the shift toward data-center infrastructure

The initial stock-market reaction was notably positive for an acquisition of this size. SLB shares rose about 3.8% following the announcement, according to Reuters, despite the company agreeing to deploy approximately $3.4 billion of cash and assume another $700 million of debt.

The shares also reached a new 52-week high of $58.86 during August 31 trading. SLB had already been performing strongly before the transaction, with the stock up roughly 51% year to date and almost 60% over the preceding 12 months when the new high was reached.

That reaction is important because acquiring companies frequently experience share-price weakness when investors question purchase prices, integration risks or increased leverage. In this case, the market appears initially more focused on Kelvion’s growth exposure and the potential for SLB to participate more directly in the AI infrastructure spending cycle.

SLB has also attempted to address concerns about balance-sheet pressure. Management expects net debt to adjusted EBITDA to remain within its previously stated through-cycle ceiling of 1.5 times following the transaction, preserving what it describes as a strong investment-grade balance sheet.

The company additionally reaffirmed plans to return more than $4 billion to shareholders during 2026 through dividends and share repurchases. SLB expects shareholder distributions during 2027 to be at least consistent with the 2026 level, although formal targets will be determined during the annual planning process.

Those commitments help explain why the acquisition has not immediately triggered major capital-return concerns. Investors are effectively being told that SLB believes it can finance Kelvion, preserve reasonable leverage and continue substantial distributions while building a new growth business.

The central risk is execution. SLB must integrate a large industrial manufacturer, achieve projected synergies and nearly double its combined data-center business within a relatively short period if it is to reach the upper end of its 2028 targets. A slowdown in AI capital expenditure or delays in data-center construction could also affect those projections.

Yet the strategic direction is increasingly clear. SLB is using capabilities developed across energy engineering, manufacturing and large-scale infrastructure to move into markets where electricity and thermal management have become essential to the next wave of computing investment. Kelvion gives the company immediate scale in one of the most constrained parts of that ecosystem.

If the 2028 targets are achieved, the $4.1 billion acquisition could ultimately be viewed less as diversification away from oilfield services and more as the creation of a second major infrastructure growth platform. The strong initial share-price response suggests investors are currently willing to give SLB that opportunity.
