Everyone wants to talk about the chips. Quanta Services would like a word about the wires.

Quanta Services (NYSE: PWR), a Houston-based infrastructure contractor, reported record quarterly revenue of $9.56 billion for the second quarter of 2026, up 41.1% from the same period a year earlier. The result lands as Big Tech's data center spending is pegged at $735 billion — a framing highlighted by The Motley Fool — and every one of those facilities requires substantial volumes of electricity delivered reliably. Before a single model trains or a single query runs, that power has to move across high-voltage lines and through substations — precisely the work contractors like Quanta are hired to perform.

The Numbers Behind the Surge

The quarterly figure was not a one-off spike. Trailing twelve-month revenue through June 2026 reached $32.91 billion, a 26.3% increase year over year. Full-year 2025 revenue came in at $28.48 billion, up 20.3% from 2024.

Management raised its 2026 revenue guidance to a range of $39.3 billion to $39.7 billion. That forecast leans on a record backlog of $53.4 billion at the end of the second quarter — the value of contracted work not yet completed, and a standard gauge of future revenue for engineering and construction firms.

There is also a broader runway. Quanta's research findings point to a 25% increase in transmission pipeline growth, bringing that figure to $170 billion.

Why a Contractor Is Suddenly a Growth Story

Quanta's core business is electric power transmission and distribution. The company builds and maintains the lines, substations, and related infrastructure that carry electricity from where it is generated to where it is used. Electric infrastructure solutions represent the bulk of its activity.

Alongside traditional utility clients, Quanta now works with hyperscale data center operators — the giant cloud and AI companies building facilities that consume electricity on an industrial scale. For those operators, grid connection is a prerequisite: no matter how advanced the hardware inside, a data center does nothing until power reaches the building.

Wall Street has taken notice. Bernstein upgraded Quanta to Outperform on September 24, 2026, with a price target of $775. The stock has recently traded in a range of $640 to660.

Bernstein's case centers on Quanta's self-performing model, meaning the company deploys its own skilled workforce rather than farming jobs out to subcontractors. Quanta self-performs on 80-85% of its projects. That structure gives the company direct control over how work is scheduled and executed — a detail that carries weight when utility and data center clients are racing to bring new capacity online.

What the Backlog Means for the Grid and for Investors

The most important number here may be the backlog rather than the revenue. A $53.4 billion book of signed work gives Quanta visibility that many growth companies would envy, and it explains why management felt comfortable lifting guidance. It also offers a window into where the physical grid work is headed: converting that signed work into completed projects is how new transmission lines, substations, and related infrastructure actually get built.

Visibility is not the same as certainty, however. Backlog can shift if customers delay projects, if permitting drags, or if the economics of data center buildouts change. Quanta's current momentum is closely linked to the capital spending plans of a small group of very large technology companies, plus utilities racing to keep up with them.

With shares trading in the $640 to $660 range, Bernstein's $775 target suggests the firm sees room above that level.

What to watch next: whether Quanta can convert its backlog into revenue on schedule, whether the 2026 guidance range holds or moves again, and whether hyperscalers keep their data center budgets on the current trajectory.
