Jacobs Solutions Inc. (J) | The Buildout — AI Infrastructure

The Verdict

Jacobs is a professional-services firm that designs and program-manages physical infrastructure — data centers, semiconductor fabs, water treatment plants, transmission lines and highways — but does not own the assets. In the AI build-out it sits on the design and delivery side: it engineers the data centers that house AI compute, the semiconductor facilities that supply the chips, and the power and water systems those sites require. The client's balance sheet carries the capital, and Jacobs' role is to turn that capital commitment into a functioning facility on schedule. Its revenue therefore depends on how quickly customers convert announced spending into awarded engineering scope.

Earnings Beat

Jacobs reported a record Q3 FY2026, with adjusted net revenue growth of more than 8% year over year, all organic. Adjusted EPS was $1.84, up about 14%, the sixth straight quarter of double-digit adjusted EPS growth. Adjusted EBITDA rose 17% year over year at a 15.2% margin, 109 basis points better than a year ago. The Infrastructure & Advanced Facilities segment set a quarterly record at nearly $2.1B of net revenue, up 10%. Consolidated backlog reached $29B, up 27%, and management said the direct AI build-out is now 11% of adjusted net revenue.

Management tone: Between the Q2 and Q3 FY2026 calls, management's guidance posture stayed the same — a third consecutive raise — while the disclosures around it changed. Backlog growth accelerated from $27B, up 22%, to $29B, up 27%. Management hardened its AI sizing to a single figure with a stated sequential gain and extended pipeline visibility from 6–9 months to 2–3 years. It delivered its leverage target a quarter early and raised its capital-return floor. Against that, it named three soft spots without prompting — PA Consulting's U.K. disruption, the persisting environmental headwind, and a temporary Middle East pause — and deferred the FY2027 growth algorithm to the next call.

Management Guidance

On the Q3 FY2026 call management raised FY26 adjusted net revenue growth to 9.5%–10%, narrowed the adjusted EBITDA margin range to 14.7%–14.8%, raised adjusted EPS to $7.20–$7.30, and lifted the adjusted free cash flow margin forecast to 8%. For Q4 FY2026 specifically it guided adjusted EBITDA margin to approximately 16%, net revenue growth of approximately 14% (the extra week accounts for about 6%–7%, so normalized growth is about 8%), a tax rate of roughly 27.5%, and quarterly free cash flow of approximately $150 million. Management deferred the FY2027 growth algorithm to the next call, anchoring only to growth 'at least in line with the long-term average,' and said FY2027 free cash flow margin guidance would come in FY2027.

Trajectory

Adjusted net revenue growth has held above 8% year over year, and the business carries a record $29B backlog, up 27% year over year, at trailing-twelve-month book-to-bill of 1.4x gross and 1.2x net. Adjusted EBITDA margin has stepped up every quarter of FY2026 — 13.4%, then 14.1%, then 15.2% — with about 16% guided for Q4. Management attributes the expansion to operating leverage, global delivery, commercial models and PA cost synergies, not to AI mix, which it says helps more in FY2027 and beyond. Two offsets show in the reported numbers: Water & Environmental grew only a little more than 1% in Q3, and PA Consulting's revenue was flattish. The consolidated gross margin and GAAP operating lines are distorted by pass-through revenue, which carries near-zero margin, and by a large one-time restructuring and transaction charge in Q2 FY2026 — so the adjusted figures are the cleaner read on the underlying trend.

The Model

The model projects FY+1 revenue of $10,397M and EBITDA of $1,539M, a 14.8% margin, and FY+2 revenue of $11,281M and EBITDA of $1,749M, a 15.5% margin. Dispersion across the five runs behind those medians is wide. The near term is anchored by the record backlog and the Q4 guideposts management has already given — roughly 16% adjusted EBITDA margin on approximately 14% net revenue growth, about 8% normalized. FY+2 depends on the deferred FY2027 growth algorithm converting the data-center and semiconductor pipeline into revenue, on PA Consulting returning to growth, and on Water & Environmental inflecting.

Projections are the median of 5 independent model runs. The model’s revenue sits 4.3% above analyst consensus.

On the Q3 FY2026 call management raised FY26 adjusted net revenue growth to 9.5%–10%, narrowed the adjusted EBITDA margin range to 14.7%–14.8%, raised adjusted EPS to $7.20–$7.30, and lifted the adjusted free cash flow margin forecast to 8%. For Q4 FY2026 specifically it guided adjusted EBITDA margin to approximately 16%, net revenue growth of approximately 14% (the extra week accounts for about 6%–7%, so normalized growth is about 8%), a tax rate of roughly 27.5%, and quarterly free cash flow of approximately $150 million. Management deferred the FY2027 growth algorithm to the next call, anchoring only to growth 'at least in line with the long-term average,' and said FY2027 free cash flow margin guidance would come in FY2027.

What Could Go Right — and Wrong

Looking Ahead

Over the next 12 months the calendar is anchored by the Q4 FY2026 call, where FY2026 actuals, a fourth consecutive bookings print and the deferred FY2027 growth algorithm all land together. Two segment recoveries are on a near-term clock: PA Consulting's Q4 sequential revenue growth and the Water & Environmental inflection management says is 'right in front of us.' Further out, the Hut 8 Beacon Point campus targets initial energization in 2027, semiconductor pipeline growth is framed as extending into 2027, and PA's at least $20M of annual cost synergies are timed to FY2027. IIJA funding flows carry a possible extension going into December, with only about 50% spent.

The Company

Jacobs is a global professional-services firm. Its 10-K describes end-to-end capabilities from advisory and consulting through design, program delivery and lifecycle management, across advanced manufacturing, cities and places, energy, environmental, life sciences, transportation and water. In plain terms it sells engineering labor, design and program management: it draws the plans for a data center, a semiconductor fab, a water treatment plant, a transmission line or a highway, and increasingly runs the delivery program on the owner's behalf — but the client owns the asset and the client's balance sheet carries the capital. Its AI linkage runs through data center design, engineering, program management and EPCM; semiconductor facility design and engineering; power and transmission infrastructure; and water and environmental infrastructure for data centers. On the PA Consulting side it also provides AI and digital advisory. The 10-K profile cites a global team of approximately 43,000; the Q3 FY2026 call references more than 47,000 employees.

Jacobs reports two segments: Infrastructure & Advanced Facilities, or I&AF, and PA Consulting. On the Q2 FY2026 filing, I&AF was about 85% of adjusted net revenue and PA about 15%, and all pass-through revenue sits in I&AF — one reason the two carry very different margin profiles. The company is asset-light: management says about 1% of revenue is CapEx, with properties primarily office space in the United States, United Kingdom, Australia, India, Canada, Poland and the United Arab Emirates. The structure changed recently and substantially. Jacobs completed the Separation Transaction on September 27, 2024, selling its Critical Mission Solutions and Cyber & Intelligence businesses to Amentum, and closed the PA Consulting Transaction on March 20, 2026, buying the remaining share capital of PA, of which it previously held about 71%.

Business Segments

Competitive Landscape

Jacobs competes across three groups, as its 10-K lists them: engineering-consulting peers such as AECOM, Tetra Tech, WSP, Arcadis, Mott MacDonald, Stantec and Parsons; construction-program peers such as Bechtel, Fluor, Mace and AtkinsRealis; and strategy and consulting firms such as Accenture, Capgemini, Deloitte, KPMG, PwC, Bain and McKinsey — the last group being the competitive set for PA. The evidence for Jacobs' position is specific rather than general: a repeat sole-source EPCM award from Hut 8, a two-decade engineer-of-record relationship with Intel, a 40-year U.S. Navy partnership, and relationships with semiconductor manufacturers spanning over 50 years. ENR has ranked Jacobs the #1 design firm, a position the source says it has held seven times in eight years, plus #1 data center firm and #1 in aviation.

Supply Chain

Jacobs is a services layer with minimal self-performed physical scope, and its 10-K names third-party dependence as a risk. Hut 8's Tier 1 model pairs American Electric Power on power, Vertiv on equipment and Jacobs on EPCM. Only Hut 8 names Jacobs back by name.
