SLB Stock Surged With Its Sector, But Its Fastest-Growing Line Was Not Drilling

The business line that had the least to do with drilling budgets was the one management kept naming, quarters before the price caught up.

SLB (SLB) has gained about 64% over the past year, against 20% for the S&P 500, and sits just below its 52-week high. A move that size usually reads as a surprise. This one should not have: in the quarters before it began, the company was already reporting which parts of the business were growing fastest, and they were not the drilling parts.

Hyperscalers Showed Up In The January 2025 Disclosures

Alongside its 2024 results in January 2025, the company described a growing exposure to data center infrastructure solutions, sold to hyperscalers. That activity and its low-carbon work together brought in more than $850 million during 2024. Where the data center piece sat mattered more than its size: in North America, where SLB expected oil and gas activity to fall on lower announced US land capital spending, data center revenue was already growing rapidly, supporting growth outside the core business.

A Slowdown On Top, Signed Contracts Underneath

The reported trend pointed the other way: as of fiscal Q2 2025, trailing-twelve-month revenue was up just 0.9% year over year, against an average of 13.1% a year over the prior three fiscal years. Underneath that deceleration, SLB said on its April 2025 first-quarter call that two years of engagement with the hyperscalers it already worked with on digital had turned into contract awards for manufacturing services and modular cooling units, fulfilled from a plant in Louisiana. That work, with carbon capture, geothermal and critical minerals, was on pace to pass $1 billion in 2025. The data center line, sold to hyperscalers, is a different proposition from the Trefis High Quality Portfolio, which does not depend on the handful of largest technology names to produce its returns.

By July 2026 Management Was Guiding The Data Center Line To A Run Rate

Those early disclosures stopped being a footnote with the second-quarter 2026 results on July 24, 2026. Data Center Solutions revenue rose 33% sequentially and 80% year over year, and management now expects that line alone to exit 2027 at an annualized run rate above $2 billion, with backlog already in place to cover it. That run rate is still small: a full year of it would not reach the roughly $9 billion SLB booked in the June 2026 quarter alone. The scope is widening: on July 14, 2026, SLB agreed to an alliance with Liberty Energy for modular infrastructure and integrated power generation, and the work now includes design, engineering, and system integration.

Legible In Advance, Just Not On The Timing

So were the signs actionable? Partly. The direction was legible, and the company said so plainly before the price moved. The timing was not. Over the same window, BKR returned 41.5%, HAL 66.0% and FTI 108.1%, against SLB’s own 63.7%, so SLB landed mid-pack in a sector that re-rated as a whole, helped by long-cycle final investment decisions that third-party reports expect to rise roughly 30% year on year in 2026.

What matters now is the gap between a chart that has already run and an outlook still pointing higher: management has guided fourth-quarter 2026 revenue above $10 billion, a guide it says remains dependent on conditions. Sorting one from the other is what a guidance-driven momentum screen is built to do.

Reading The Signs Early Is Not The Same As Sizing The Bet

Reading one company’s disclosures closely is a skill, and it is not a portfolio. Deciding what you hold and how much of it, by rule rather than by conviction, is the part that compounds. That portfolio has a track record of outpacing the three major indices – the S&P 500, S&P Mid-cap, and Russell 2000.
