J vs STN: Which Is the Better Buy in 2026?

Same yardstick, side by side (as of August 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.

Reading it: STN is the cheaper of the two on forward earnings, but cheaper is not the same as better. Pair the valuation with growth (how far the forward P/E sits below the trailing P/E) and risk (beta) before you decide.

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. J and STN 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 J and STN 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.

Jacobs Solutions Inc. (NYSE: J) is a Dallas-based professional services firm of roughly ~47,000 people that designs, plans and manages large physical assets: water and wastewater systems, highways and transit, semiconductor fabs, pharmaceutical plants, power and grid infrastructure, and increasingly data centers. It reports in two segments. Infrastructure & Advanced Facilities is the bulk of it, generating ~$3.75 billion of gross revenue in the June 2026 quarter, of which ~$2.09 billion was adjusted net revenue after stripping pass-through costs, at a segment operating margin near ~12.8%. PA Consulting, the UK-based strategy and innovation consultancy, is much smaller at ~$330 million of quarterly revenue but far richer, running near ~22% segment operating margin. Jacobs completed the purchase of the remaining PA Consulting shares on March 20, 2026 for aggregate initial consideration of about ~£1.21 billion, taking ownership from roughly 71% to full.

Stantec sells professional services, not products. Roughly 32,000 engineers, architects, scientists and planners bill time on projects across five business lines: Water, Environmental Services, Infrastructure, Buildings, and Energy & Resources, reported in three geographic segments (United States, Canada and Global). The work is unglamorous and specific: designing water and wastewater treatment upgrades, transit and highway projects, hospitals, semiconductor and advanced-manufacturing plants, permitting and remediation studies. Clients skew public sector, so revenue follows municipal, state, provincial and national capital programs. Recent examples show the shape of it: Stantec was named a preferred bidder as a primary designer on the multibillion-pound Scottish Water investment program, and in May 2026 joined a joint venture to deliver Greater Western Water's infrastructure program in Australia.

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

• J drivers: Backlog is growing faster than revenue; The AI build-out has reached the engineering layer.
• STN drivers: Water and wastewater capital cycles; Record backlog converting to billable hours.

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 headline growth rate is flattered by pass-through revenue, which nearly doubled the gap between gross and net revenue growth in the June quarter, so a mix shift toward construction-heavy work can inflate revenue while adding nothing to profit. For STN, public budgets are the demand curve here, so a funding freeze, an election-driven pause or a slower federal appropriations cycle in the United States shows up as delayed starts and lower utilization.

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 J if you believe its drivers more; STN 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 J and STN guides.

J. At about ~$145 a share the market capitalization is roughly ~$16.9 billion, which is close to ~20 times the midpoint of guided adjusted EPS and near ~48 times trailing GAAP EPS. That spread is not an accounting curiosity: it reflects ~$402.9 million of restructuring and transaction charges booked in the first nine months of fiscal 2026, ~$105.5 million of intangible amortization, and a temporarily elevated tax rate from the PA Consulting purchase. Adjusted EBITDA guidance of ~14.7% to ~14.8% on adjusted net revenue implies roughly ~$1.4 billion, putting enterprise value near ~14 times that figure.

STN. Stantec reports in Canadian dollars while trading in US dollars on the NYSE, so screener figures often mix currencies and should be checked against the company's own releases. The 2026 guide of ~8.5% to ~11.5% net revenue growth with ~17.6% to ~18.2% adjusted EBITDA margin was reaffirmed alongside Q1 results in May 2026. A ~23x trailing multiple against a 52-week range of roughly $66 to $114 shows most of the past year's move came from the multiple, not from the earnings line.

Headline figures (approximate, August 2026): J shows revenue (ttm, gross) ~$14.2B, adjusted net revenue (9m fy2026) ~$7.0B, FY guide ~9.5% to 10% growth, adjusted eps (fy2026 guidance) ~$7.20 to ~$7.30, gaap eps (ttm) ~$2.86; STN shows net revenue (fy2025) ~C$6.5 billion, up ~10.7%, adjusted ebitda (fy2025) ~C$1.14 billion, ~17.6% margin, q1 2026 adjusted eps ~C$1.33, up ~14.7%, contract backlog ~C$9.0 billion, up ~13.2% y/y.

J and STN 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. Walnut can show your combined J and STN exposure against your real portfolio. It is not an investment adviser.
