SLB vs WHD: Which Is the Better Buy in 2026?

Same yardstick, side by side (as of September 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.

The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. SLB and WHD share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.

This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined SLB and WHD exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker. Walnut is not an investment adviser.

SLB (formerly Schlumberger) is a multinational oilfield services and energy technology company founded in France in 1926 and now incorporated in Curacao, with principal offices in Paris, Houston, London, and The Hague. It operates across four divisions: Well Construction, Reservoir Performance, Production Systems, and a newly reported standalone Digital division, providing services that span the full upstream oil and gas lifecycle from seismic imaging and reservoir characterization through drilling, completions, and production optimization, as well as emerging capabilities in carbon capture, geothermal, and AI-powered data platforms. The company operates in more than 120 countries and employs people of more than 140 nationalities, giving it the broadest international footprint in its sector. In July 2025 SLB closed its acquisition of ChampionX in an all-stock deal valued at approximately $7.75 billion, its largest purchase since Cameron International, adding production chemistry and artificial lift capabilities. CEO Olivier Le Peuch, who joined the company in 1987 as an electrical engineer and has held the top role since August 2019, has led a deliberate pivot toward platform-based digital solutions and energy transition technologies, culminating in the 2022 rebrand from Schlumberger to SLB.

Cactus, Inc. designs, manufactures, sells, and rents pressure control and spoolable pipe technologies for the oil and gas industry. It reports in two segments: Pressure Control, which sells wellhead and pressure control equipment under the Cactus Wellhead brand along with field installation and service, and Spoolable Technologies, which supplies FlexSteel spoolable pipe and fittings for moving oil, gas, and water. The company was founded in 2011 and primarily serves US onshore basins, with a growing footprint in Australia, Canada, the Middle East, and other international markets.

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

• SLB drivers: International Upstream Spending Cycle; Digital Division as a High-Margin Growth Engine.
• WHD drivers: International expansion via the Baker Hughes JV; Spoolable pipe (FlexSteel) diversification.

A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: The primary risk is oil price volatility: decisions by OPEC+ on production quotas directly influence the capital expenditure budgets of SLB's E&P clients, and a sustained decline in crude prices could quickly reverse the international spending cycle that underpins the bull case. For WHD, cactus is highly cyclical and its results move with oil and gas prices and customer drilling and completion budgets, so a downturn in the US land rig count would pressure both volumes and pricing.

Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick SLB if you believe its drivers more; WHD if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the SLB and WHD guides.

SLB. SLB's full-year 2025 revenue of approximately $35.7 billion reflects modest single-digit growth over fiscal 2024's $36.3 billion, with margins under modest pressure as international activity moderated and the ChampionX integration costs flowed through. The trailing P/E of roughly 17x to 22x is broadly in line with SLB's five-year average and represents a meaningful discount to the company's 10-year historical average, which some analysts interpret as a valuation opportunity if the digital re-rating thesis plays out. Operating margin weakened to approximately 11.9% on a GAAP basis in the most recent reported period, underscoring that the earnings quality story depends heavily on the pace of Digital division scaling and ChampionX synergy realization.

WHD. Cactus trades at a roughly market-level earnings multiple for an oilfield equipment specialist, with the newly consolidated international JV lifting revenue while lowering the blended margin (Q1 2026 adjusted EBITDA margin fell to about 25.8 percent from 32.7 percent). Reported net income to common was distorted by a large non-controlling-interest accretion charge, so adjusted EBITDA and free cash flow are the cleaner lenses. Figures are approximate and vary by source and reporting date.

Headline figures (approximate, 2026-06-27): SLB shows revenue (fy 2025) ~$35.7 billion, revenue (q1 2026) ~$8.72 billion, adjusted ebitda margin (h1 2025) ~23.9%, diluted eps (ttm, dec 2025) ~$2.26 (GAAP); WHD shows revenue (ttm) ~$1.1B, q1 2026 revenue ~$388M, q1 2026 adjusted ebitda ~$100M, market cap ~$3.7B to $4.4B.

SLB and WHD are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme.
