MTZ vs PWR
Which Stock Would AI Choose? MasTec (MTZ) vs. Quanta Services (PWR) Stock Comparison
Key Takeaways
- Same theme, different scale: Both MTZ and PWR are infrastructure contractors leveraged to grid modernization, electrification, and AI-driven data-center demand, but Quanta Services operates at roughly twice MasTec's revenue scale.
- Momentum gap: Quanta Services has delivered stronger recent relative performance, while MasTec's shares have pulled back despite record results.
- Growth vs. stability: MasTec is growing revenue and adjusted earnings faster, while Quanta offers more consistent cash generation and a larger backlog.
- Segment contrast: MasTec's Communications segment is a near-term drag, whereas Quanta's Electric segment is its dominant growth engine.
- Valuation divergence: Quanta trades at a materially higher earnings multiple than MasTec, reflecting its stronger market positioning and steadier execution.
Introduction
Investors tracking the infrastructure and power-construction sector frequently weigh MTZ against PWR. Both companies sit at the center of durable spending trends — aging grid replacement, renewable interconnection, electrification, and the rapid buildout of data centers powering artificial intelligence — yet their business mixes, financial profiles, and recent stock behavior differ meaningfully. This stock comparison examines their relative performance, growth drivers, and market positioning. It is most relevant to growth-oriented investors, sector allocators, and traders seeking to understand how two direct peers stack up in the current market environment without taking a one-sided view of either name.
MTZ Overview and Recent Performance
MasTec, Inc. is a North American infrastructure engineering and construction company focused on communications, energy, utility, power delivery, clean energy, and pipeline projects. In recent market activity, the stock has shown a mixed trajectory: shares advanced strongly earlier in the period before pulling back over recent months, reflecting a more volatile pattern than some peers.
The underlying business, however, has performed well. In its most recent reported quarter, MasTec posted record revenue growth above 23% year over year and raised its full-year guidance for revenue, adjusted EBITDA (earnings before interest, taxes, depreciation, and amortization), and adjusted earnings per share. Its 18-month backlog reached a record level, up roughly 30% year over year. The July 2026 acquisition of The Superior Group, an electrical contractor serving data centers, further deepens its mission-critical exposure.
Offsetting these strengths, MasTec's Communications segment has been a notable weak spot, with declining segment earnings and margin contraction tied to lower wireless revenue and wireline project deferrals. Negative free cash flow and elevated net debt have also drawn scrutiny, even as management points to improving second-half cash generation.
PWR Overview and Recent Performance
Quanta Services, Inc. is a leading specialty contractor providing integrated infrastructure solutions across electric power, pipeline, industrial, and communications markets. Its recent stock performance has been comparatively strong, with shares advancing substantially on a year-to-date basis even after a modest pullback in recent months.
Quanta's fundamentals have supported that performance. In its most recent quarter, it reported record revenues and adjusted earnings per share, with growth exceeding 25% at the top line. Total backlog reached a record of approximately $48.5 billion, and management raised full-year expectations across revenue, adjusted EBITDA, and adjusted diluted earnings per share. The company completed several acquisitions in late 2025, including electrical and transmission-focused businesses, strengthening its craft-skilled platform.
Quanta's "Compounding Model" and its positioning across converging utility, generation, and large-load markets — which management estimates as a roughly $2.4 trillion total addressable market through 2030 — underpin its long-term outlook. Analysts have maintained a broadly constructive stance, with a consensus Strong Buy rating and steadily rising price targets.

Head-to-Head Comparison
Although both companies are infrastructure contractors, their profiles diverge in several ways. Business model: Quanta is more concentrated in electric power and utility infrastructure, while MasTec maintains a broader mix spanning communications, clean energy, pipelines, and power delivery. Growth drivers: MasTec is expanding faster on a percentage basis, with full-year revenue and adjusted EPS guidance implying growth near 27% and 42%, respectively; Quanta is growing from a much larger base but at a comparatively lower rate. Momentum: Quanta has shown steadier relative performance, whereas MasTec has been more volatile. Risk factors: MasTec faces segment-specific headwinds in Communications and negative free cash flow, while Quanta carries a premium valuation that leaves less room for disappointment. Market sentiment: Quanta holds a Strong Buy consensus, while MasTec's analyst sentiment is more mixed following its Communications softness.
Tickeron AI Verdict
Based on observable factors, Tickeron's AI would likely favor PWR in the current environment. Quanta Services combines more consistent trend behavior, a record backlog, steadier free cash flow generation, and stronger analyst sentiment — qualities that typically align with higher-probability trend continuation. MasTec's faster growth and lower valuation are genuine merits, but its Communications drag, negative free cash flow, and choppier recent price action introduce greater uncertainty. This is a probabilistic assessment of relative positioning rather than a forecast, and it could shift as new earnings data and market conditions emerge.

Long-Term Analysis
It is best to consider a long-term outlook for a ticker by using Fundamental Analysis (FA) ratings. The rating of 1 to 100, where 1 is best and 100 is worst, is divided into thirds. The first third (a green rating of 1-33) indicates that the ticker is undervalued; the second third (a grey number between 34 and 66) means that the ticker is valued fairly; and the last third (red number of 67 to 100) reflects that the ticker is overvalued. We use an FA Score to show how many ratings show the ticker to be undervalued (green) or overvalued (red).
MTZ’s FA Score shows that 0 FA rating(s) are green while PWR’s FA Score has 3 green FA rating(s).
- MTZ’s FA Score: 0 green, 5 red.
- PWR’s FA Score: 3 green, 2 red.
Short-Term Analysis
It is best to consider a short-term outlook for a ticker by using Technical Analysis (TA) indicators. We use Odds of Success as the percentage of outcomes which confirm successful trade signals in the past.
If the Odds of Success (the likelihood of the continuation of a trend) for each indicator are greater than 50%, then the generated signal is confirmed. A green percentage from 90% to 51% indicates that the ticker is in a bullish trend. A red percentage from 90% - 51% indicates that the ticker is in a bearish trend. All grey percentages are below 50% and are considered not to confirm the trend signal.
MTZ’s TA Score shows that 5 TA indicator(s) are bullish while PWR’s TA Score has 6 bullish TA indicator(s).
