Stantec Inc. (STN) | The Buildout — AI Infrastructure

The Verdict

Stantec is a global design and engineering firm. Its teams plan, design and manage infrastructure projects — data centers, water and wastewater plants, transit lines, and energy and resource facilities. In the AI build-out its role is derivative rather than direct: it does not build or own compute, but its Buildings group designs the hyperscale campuses and semiconductor plants that AI workloads run in, and its Water business covers the cooling and process water those sites need. It sells professional services, not hardware or assets, so its economics depend on billable people, project pricing and utilization.

Earnings Beat

Stantec reported revenue of $1,254.4M in its fiscal second quarter of 2026, with a gross margin of 54.5% and EBITDA of $246.4M, a 19.6% EBITDA margin. On the company's adjusted basis the quarter set a record Q2 adjusted EBITDA margin of 18.7%, up 90 basis points year over year. Growth remained acquisition-led: 3.7% organic against 7.1% from acquisitions, primarily the Page purchase, and project margins — which the CFO calls the spine of the bottom line — came in at 54.5% of net revenue, up 30 basis points.

Management tone: Management's tone was confident on margins and backlog and direct about the U.S. shortfall. Against the Q1 2026 call, the U.S. message shifted from expected organic acceleration across all five business verticals to flat, organic guidance was lowered while the margin outlook was raised, and confidence moved to the Global segment, which the CFO described as being in a high-single-digit environment for several quarters to come. Management volunteered negatives rather than waiting to be asked: it said Q2 organic was probably underreported by a smidge because of the way the company does things, and that the margin guide embeds some conservatism.

Management Guidance

For FY2026 management guides net revenue growth of 8.5% to 11.5%, an adjusted EBITDA margin of 17.8% to 18.3% (raised and narrowed from 17.6%-18.2%), adjusted EPS growth of 15% to 18%, and organic net revenue growth in the mid-single-digit range, lowered from mid-to-high single digit. By geography, the U.S. and Canada are guided to mid-single-digit organic growth and Global to high single-digit, with Canada's growth led by Water, Buildings and Environmental Services. Guidance excludes additional acquisitions. Management attributed the gap between roughly 80 bps of H1 margin expansion and about 15 bps implied for the full year to H2 workforce timing, and said the guide carries a little conservatism.

Trajectory

The profit line has been the stronger of the two stories. Adjusted EBITDA margin expanded year over year for roughly seven consecutive quarters, reaching a record-for-a-second-quarter 18.7% in Q2 2026, and the trailing-12-month margin is 18%. Project margins, which management calls the spine that drives the bottom line, were 54.5% of net revenue, up 30 basis points. The top line has been more mixed: acquisition growth has been running roughly double organic growth through 2026, at 7.1% against 3.7% in Q2, with Page the main contributor. Backlog has compounded to a record, about 13 months of work, growing 17.5% year over year and 7% organically. Management guides to slower organic growth and a moderating pace of margin expansion in the second half, because converting backlog requires adding people.

The Model

The model projects FY+1 revenue of $6,050M and EBITDA of $1,092M, an 18.05% margin, rising to FY+2 revenue of $6,625M and EBITDA of $1,226M, an 18.5% margin. The near term is anchored on record backlog, about 13 months of work, and on the mid-single-digit organic growth management guides for FY2026 alongside acquisition contributions. FY+2 assumes the margin trend continues past the 17.8%-18.3% range guided for FY2026, which depends on the hiring planned to convert backlog not stalling utilization.

What Could Go Right — and Wrong

Looking Ahead

Over the next 12 months the tests are specific and dated. Management has said U.S. organic growth should accelerate in the second half, with Page moving into the organic line in Q3 2026 and Canada guided to mid-single-digit organic growth led by Water and Buildings. The CEO transition takes effect October 1, 2026, and the December 2026 Investor Day is where management is expected to address the project-margin ceiling and set the next multi-year plan. Policy runs on its own calendar: the IIJA new-award window closes in September 2026, and reauthorization is expected only after the midterms and into early 2027. Management also said it expects more M&A over the next 12 months than in the last 12.

The Company

Stantec is a global design and engineering firm. The FY2025 40-F describes it as 'a global leader in sustainable engineering, architecture, and environmental consulting,' whose professionals deliver the expertise communities need to manage aging infrastructure, demographic change and the energy transition. It works across five business lines — Infrastructure, Environmental Services, Water, Buildings and Energy & Resources. For the AI build-out the relevant pieces are Buildings, where teams design hyperscale data centers, semiconductor plants and advanced manufacturing, and Water, which covers cooling and process water bundled into those projects plus municipal and industrial treatment. It is a services firm, not an owner-operator: the 40-F lists no plants, and every infrastructure item the company discusses is work it designs, engineers, manages or advises on.

Operations are reported through three segments — Canada, the United States and Global — which the 40-F describes as the company's operating and reportable segments for its consulting services. Growth is run through a mix of acquisitions and hiring: the company closed the Page acquisition, added Niche, a 200-person Australian engineering and environmental consultancy, effective July 31, 2026, and built its India global delivery center to roughly 2,000 people ahead of a year-end goal, with a second office in Pune and plans to expand to other cities. It funds this at 1.3x net debt to adjusted EBITDA, inside a stated internal target range of 1x to 2x.

Business Segments

Competitive Landscape

The competitive set is a group of global engineering and consulting majors. Jacobs, Tetra Tech, Parsons and Legence each name Stantec as a competitor in their own filings. Management's argument is that clients are consolidating work into larger, more integrated programs awarded to a smaller group of providers, so the bidder set on the biggest jobs narrows to what management calls the big majors, which it says allows some pricing power in a number of instances. Management also describes the industry as fragmented, estimating the largest U.S. firm at only 6% to 8% market penetration.

Supply Chain

Stantec sits in the design and engineering layer of infrastructure projects rather than in materials or equipment supply. Its wiring map lists four generic suppliers with no quotes, none of which appear to be project-specific relationships. No neighbor transcript in the material mentions Stantec by name.
