Quanta Services
Summary
What they do:
Largest specialty infrastructure services company in the US — builds and maintains electrical transmission lines, substations, renewable energy interconnections, and data center electrical systems. The only contractor that can build the entire power delivery chain from generation source to data center interior.
Why they matter:
Data centers can't operate without power infrastructure. Quanta builds the transmission lines that bring utility power to the site, the substations that step it down, and the electrical systems inside the building. With $44B backlog (+27.5% YoY) and data centers as the fastest-growing segment, Quanta is the picks-and-shovels play on the data center power bottleneck.
Recent performance:
FY2025 revenue $28.5B (+20% YoY, record). Q4 revenue $7.84B (+19.7%). FY2026 guided $33.25-33.75B (+17-18% YoY) with EPS $12.65-13.35. Backlog $44B. Stock ~$590, near all-time high. Market cap ~$90B.
Our Verdict
The largest electrical contractor in America with the unique ability to build every layer of power infrastructure from utility grid to server rack — record $44B backlog and 20%+ EPS growth guidance confirm the data center power supercycle is translating directly into Quanta's order book.

When a hyperscaler decides to build a 500MW data center campus, the first constraint isn't computing hardware — it's power. Can the local grid deliver 500MW? If not, who builds the new transmission line? Who constructs the substation? Who wires the interior of the data center? Quanta Services does all three.
Quanta is the largest specialty infrastructure services company in North America, operating in three segments: Electric Power (~55% of revenue) builds and maintains transmission lines, substations, and distribution networks for utilities. Renewable Energy (~25%) builds wind farms, solar installations, and the transmission interconnection that connects them to the grid. Underground Utility and Infrastructure (~20%) handles gas, telecommunications, and industrial infrastructure.
The company's unique competitive position is vertical integration across the power delivery chain. Competitors like MYR Group (MYRG) focus on specific segments (T&D or C&I). MasTec (MTZ) and Pike Electric compete in selected areas. But Quanta is the only contractor with the workforce, equipment, and project management capability to handle a full-scope data center power project: building the 345kV transmission line from the utility, constructing the step-down substation on site, running the medium-voltage distribution inside the campus, and wiring every server room.
Quanta is headquartered in Houston, Texas, with approximately 52,000 employees (including 30,000+ specialized linemen and electricians). The company operates from over 400 locations across North America. FY2025 was a record year: revenue $28.5B (+20%), adjusted EBITDA $2.9B (record), adjusted EPS $10.75 (+20%). The $44B backlog — up 27.5% YoY — provides roughly 18 months of revenue visibility.
Data centers currently represent approximately 10% of revenue but are the fastest-growing component of backlog. Management has described data center-related demand as "unprecedented" and expects the segment to grow to 15-20% of revenue over the coming years as hyperscaler construction accelerates.
FY2026 guidance is aggressive: revenue $33.25-33.75B (+17-18%), adjusted EPS $12.65-13.35 (+18-24%). This implies continued acceleration in both organic growth and acquisition-driven expansion.

The Catch
Quanta Services is a services business trading at 46x forward earnings — a valuation typically reserved for asset-light technology companies, not labor-intensive infrastructure contractors with 5-7% operating margins. The $44B backlog is impressive but the margin on that backlog is narrow — electrician wage inflation of 6-8% annually can compress profitability on fixed-price contracts bid months earlier. Data centers are the fastest-growing backlog segment but still only ~10% of revenue — Quanta is primarily a utility contractor, not an AI company. And the stock's near-all-time-high price leaves no room for execution missteps, cost overruns, or cyclical moderation in utility spending.
If They Win
If data center power construction grows from 10% to 25%+ of revenue, grid modernization spending from IRA/IIJA sustains through 2030, renewable energy interconnection provides a third growth vector, operating margins expand toward 8%+ as project mix improves, and Quanta maintains its labor advantage as the constraint that limits competition, then Quanta becomes the general contractor of the AI power grid — the company that builds every mile of transmission line, every substation, and every data center electrical system that powers the AI economy. Revenue compounds to $45B+ by 2028, margins expand as data center work (higher ASP, better margins) grows as share of mix, and the current $90B market cap looks reasonable against $4B+ annual earnings power.
