Quanta Services (PWR)

Electrical infrastructure construction (Quanta) — builds the grid + data-center power

AI exposure 17% — derived from reported segment revenue, not asserted.

Where it sits

Physical Infrastructure → Grid Infrastructure Contractors · figures rebased to Q2 2026, reported 2026-07-30

Build/upgrade electric transmission, distribution, substations, renewable interconnect… leads 2 businesses in this sub-tier that together are 100% of revenue, so Grid Infrastructure Contractors is effectively the whole company rather than one leg of it.

Reported segments

• Electric Infrastructure Solutions — 75% of revenue
• Underground Utility & Infrastructure — 25% of revenue

Quanta Services (~$25B FY2025; FY2026 guided $39.3-39.7B) — infrastructure construction. Electric Infrastructure ~75% (build/upgrade transmission/distribution/substations + renewable interconnect = primary B2 Grid Contractors; building the grid for data-center power demand) + Underground ~25%. Data-center work now 15-20% of the business per management (Q2 2026), self-performing 80-90% of data-center balance-of-plant as integrated EPC. Primary B2 Grid Infrastructure Contractors. Builds the power backbone for AI data centers; competes EME/MYRG; serves utilities + hyperscalers.

How the 17% is built

• Electric Infrastructure Solutions — 75% of revenue × 22% AI-driven (disclosed). Mgmt Q2 2026 call: data-center work is 15-20% of total revenue, effectively all of it substation/transmission/interconnect scope sitting in this segment; 22% here reconciles to the midpoint of that disclosed range on the spine's 75/25 mix. Record $53B backlog, $43.8B of it Electric
• Underground Utility & Infrastructure — 25% of revenue × 3% AI-driven (estimate). Estimate, unchanged. Pipeline and broadband construction has minimal direct data-center linkage; held nominal so the rows reconcile to the disclosed 15-20% company figure

Investment read

Moat. The largest skilled-crew pool in electrical infrastructure — 85,000+ employees, ~15,500 added in 2026, an 80-85% self-perform rate, ~$250M/yr of training — plus integrated EPC that self-performs 80-90% of a data center's balance of plant, including in-house transformer manufacturing. Scale in a scarce input rather than a structural barrier: rivals hire into the same labor market.

Bottleneck / pricing power. Modest pricing power by any absolute standard — Q2 2026 adj. EBITDA margin of ~11.5% is a company record and already above the 10-11% 2030 target band, which is roughly the ceiling bid contracting delivers even with crews allocated. Scarcity shows up as volume, not price: record $53B backlog versus ~$35B a year earlier.

Role in the AI stack. The grid + data-center-power construction layer — crew scale is the edge.
