Quanta Services, Inc. PWR shares have declined 11.7% in the past three months, even as the company delivered faster earnings growth, record backlog and a higher 2026 outlook.
The pullback sharpens the investment debate. Quanta’s operating momentum supports the bull case, but its premium valuation and execution demands leave little room for disappointment.
PWR’s Fundamentals Defy the Recent Decline
Second-quarter 2026 revenues increased 41.1% year over year to $9.56 billion. Adjusted earnings rose 71% to $4.24 per share, exceeding the Zacks Consensus Estimate by 28.9%, while revenues topped the consensus mark by 12.1%.

Profitability improved across both operating segments. Electric Infrastructure Solutions revenues rose 43.6%, while Underground Utility and Infrastructure Solutions revenues increased 30.7%. Those results show that the recent stock weakness has occurred despite broad operating gains.
Quanta’s Backlog Supports Multiyear Visibility
Total backlog reached a record $53.4 billion at June 30, 2026, up from $48.5 billion at March 31. Remaining performance obligations increased to $33.6 billion, giving Quanta substantial visibility into future work.
Several large transmission and generation programs remain outside backlog while engineering, permitting and pre-construction activities continue. Their eventual inclusion could extend the opportunity, although the timing of awards may make quarterly bookings uneven.
PWR’s Raised Outlook Strengthens the Bull Case
Quanta raised its 2026 revenue guidance to $39.3-$39.7 billion from $34.7-$35.2 billion. Adjusted earnings guidance increased to $16.45-$16.95 per share from $13.55-$14.25.
The revision reflects first-half execution, better second-half visibility and expected contributions from recent acquisitions. Phalcon, Enerfab, Percheron and PSD are expected to add $1.2-$1.4 billion of 2026 revenues and $120-$140 million of adjusted EBITDA.
Quanta’s Premium Valuation Raises the Stakes
PWR trades at 44.1X forward 12-month earnings, above the Zacks sub-industry’s 27.6X, the sector’s 20.6X and the S&P 500’s 20.8X. That premium implies investors are already paying for sustained growth and reliable execution.
MasTec, Inc. MTZ offers exposure to communications, power delivery, clean-energy and pipeline infrastructure, while EMCOR Group, Inc. EME provides electrical and mechanical construction services. Both are relevant comparisons because Quanta’s valuation also exceeds their forward multiples cited in the peer analysis.
PWR’s Risks Could Prolong the Weakness
Permitting, environmental reviews, right-of-way work and regulated utility approvals can delay project starts and shift revenue timing. Quanta must also recruit and train enough craft-skilled workers to support larger programs expected to enter the field in coming years.
Fixed-price contracts can pressure margins when labor, materials or schedules move against estimates. Working-capital swings may also affect cash conversion, while the integration of four recently acquired businesses adds execution and organizational complexity.
PWR’s Growth Signals Favor Selective Optimism
The pullback makes PWR more debatable as an entry point, but not automatically inexpensive. Record backlog, raised guidance and faster earnings growth support selective optimism, while the valuation premium argues for discipline.
PWR currently carries a Zacks Rank #1 (Strong Buy), along with a Growth Score of A, Momentum Score of B and VGM Score of B. Those readings support its near-term earnings and growth profile. Still, the Value Score of F confirms that valuation remains the central restraint, even after the recent decline. You can see the complete list of today’s Zacks #1 Rank stocks here.
