Granite Construction Incorporated (GVA) | The Buildout — AI Infrastructure

The Verdict

Granite Construction is a vertically integrated civil contractor and construction-materials producer. It builds and rehabilitates roads, bridges, rail lines, airports, marine ports, and water infrastructure, and it produces the aggregates and asphalt that go into that work. Its role in the AI buildout is downstream: it performs the civil site development — earthwork, grading, concrete, and utilities — for data centers, along with the water and power generation infrastructure those sites require. Its Materials segment supplies aggregates and asphalt into the same construction. Granite is not an AI compute, hardware, or cooling supplier; it is one of the contractors that prepares the ground a data center is built on.

Earnings Beat

Granite's Q2 2026 revenue rose 29% year over year to $1.5 billion, with gross margin of 16.4%. The reported result was a GAAP net loss of $278 million, or $(6.36) per diluted share, driven by a $360 million non-operating loss on convertible-debt transactions; adjusted net income was $101 million. First-half operating cash flow reached $142 million versus $5 million a year earlier.

Management tone: Across the two calls, management's tone shifted from raising the current year to raising the framework beyond it. On the Q1 2026 call they raised FY2026 revenue, adjusted EBITDA margin, and SG&A guidance and described a 'fantastic start' for Materials. On the Q2 2026 call they raised FY2026 revenue again, introduced a higher 2027 organic growth expectation, and moved the data center topic from an ambition to a quantified CAP line. The Materials discussion became more measured against an 800 bps margin decline, which management attributed to weather and one-time plant costs. On capital structure, the tone moved to a materially de-risked balance sheet after the $600M notes and the convert retirement.

Management Guidance

For FY2026, management guides revenue of $5.3B–$5.5B, reflecting about 12% organic growth and about 10% growth from acquired companies at the midpoint. Adjusted EBITDA margin, SG&A at 8.25%–8.75% of revenue, the adjusted effective tax rate in the mid-20s, and CapEx of $140M–$160M are unchanged from the prior guide. The operating cash flow target was raised to 11% of revenue. For FY2027, management raised its organic revenue growth expectation to above 10% from 6%–8% and has pointed toward a 13.5% adjusted EBITDA margin target, stated on the Q1 call and reaffirmed broadly in Q2.

Trajectory

Revenue is accelerating on the audited data. Q2 2026 revenue was $1.5B, up 29% year over year and about 60% from the prior quarter, on a record $7.4B CAP and acquisitions. Gross margin compressed to 16.4% from 17.7% a year earlier: Construction held roughly flat against a difficult comparison, while Materials fell 800 bps on severe Southeast weather and quarry development costs. As-reported EBITDA was $172.6M, or 11.9% of revenue, against $138.8M and 12.3% a year earlier. Operating cash flow swung to $142M in the first half of 2026 from $5M a year earlier.

The Model

The model projects FY+1 revenue of $5,500M and EBITDA of $605M (11.0%), and FY+2 revenue of $6,250M and EBITDA of $762M (12.2%). The near-term anchor is the record CAP and two consecutive guidance raises, with FY+1 revenue at the top of management's $5.3B–$5.5B range. The FY+2 step-up implies continued CAP conversion, data center growth toward the ~10%-of-revenue target, and margin expansion from Materials recovery and a richer federal and mission-critical mix.

Projections are the median of 5 independent model runs. The model’s revenue sits 10.3% above analyst consensus.

For FY2026, management guides revenue of $5.3B–$5.5B, reflecting about 12% organic growth and about 10% growth from acquired companies at the midpoint. Adjusted EBITDA margin, SG&A at 8.25%–8.75% of revenue, the adjusted effective tax rate in the mid-20s, and CapEx of $140M–$160M are unchanged from the prior guide. The operating cash flow target was raised to 11% of revenue. For FY2027, management raised its organic revenue growth expectation to above 10% from 6%–8% and has pointed toward a 13.5% adjusted EBITDA margin target, stated on the Q1 call and reaffirmed broadly in Q2.

What Could Go Right — and Wrong

Looking Ahead

Over the next twelve months, the questions are whether the record CAP converts to revenue as guided, whether the data center line keeps compounding toward management's target of around 10% or better of annual revenue, and whether Materials margins recover in the second half of 2026. Management also points to $200M–$400M of 2026 acquisition spend and a few more deals in Q3/Q4 2026, and to the Q3 2026 mechanics of the $270M debt-discount amortization and an expected reduction of about 2 million adjusted diluted shares. On policy, the IIJA expiry in September 2026 and the BA250 draft are the swing factors for the public-transportation core.

The Company

Granite Construction describes itself in its FY2025 10-K as one of the largest diversified, vertically integrated civil contractors and construction materials producers in the United States. It builds and rehabilitates roads, pavement, bridges, rail lines, airports, marine ports, dams, reservoirs, and water infrastructure, and takes on complex site development, mining, solar, battery storage, and other power-related work. Its Materials segment produces aggregates, asphalt concrete, liquid asphalt, and recycled materials, both for its own construction projects and for sale to third parties. For the AI buildout, the relevant work is civil site development and the water and power generation infrastructure data centers need.

It operates two reporting segments, Construction and Materials, and describes itself as vertically integrated: the Materials arm feeds its own jobs. The 10-K's quarry table lists 34 quarries in California, 1 in Kentucky, and 81 across other states and provinces, giving it local aggregates reserves that cannot be economically shipped long distances. Its customers run from state and local DOTs to federal agencies, Class I railroads, water utilities, and private developers. Its data center experience is concentrated in its home markets, primarily the Pacific Northwest and Nevada.

Business Segments

Competitive Landscape

Granite competes in two arenas. In aggregates and construction materials, a competitor's filing names it alongside Amrize, Cemex, CRH, Eagle Materials, Heidelberg Materials, Martin Marietta, Construction Partners, and Vulcan Materials. In data center civil work, the wiring file lists heavy-civil and specialty contractors including Knife River, Sterling Infrastructure, Primoris, MYR Group, Quanta, MasTec, EMCOR, Orion, and Southland, most of them inferred rather than documented. The verified competitive watch is Knife River, a documented competitor that describes itself as a 'preferred materials vendor for a data center and hyperscaler,' is working 21 data centers, and entered Granite's Utah home market through the Morgan Asphalt acquisition — the same market as Granite's Kenny Sain deal. Granite's own framing leans on its owned aggregates reserves and 'home-market crew optionality' as the differentiator.

Supply Chain

Granite sits between equipment, materials, and trade suppliers and a customer base of state DOTs, federal agencies, and private developers. No supplied neighbor transcript mentions Granite by name; the closest verified read-through is competitor Knife River.
