Quanta Services

Quanta delivered strong second-quarter results well above guidance, with sales rising 41% year over year to $9.56 billion. It raised its 2026 revenue guidance by 13% at the midpoint, now implying around 40% growth, and lifted diluted EPS guidance to $11.41-$11.92, a 23% increase at the midpoint.

Why it matters: Quanta is benefiting from a sharp increase in electric infrastructure investment as AI-related data centers drive unprecedented growth in power demand. This surge in spending is pushing project demand ahead of available contractor capacity, creating unusually favorable conditions for growth and profitability. Near-term demand remains robust, with 12-month backlog increasing more than 15% from the prior quarter. However, we are less certain about how long this pace can continue, as low barriers to entry should attract additional capacity, and infrastructure investment could also moderate if AI-related power demand falls short of current expectations. Profitability was also strong this quarter, with diluted earnings per share rising 95% year over year to $2.96. Capacity constraints are allowing Quanta to be more selective about the projects it pursues and secure better pricing and contract terms, but we expect margin expansion to slow as industry capacity catches up with demand.

The bottom line: We are slightly increasing our fair value estimate for no-moat Quanta Services to $410 per share from $400, to account for stronger near-term growth, but our long-term outlook remains unchanged. Shares appear significantly overvalued as we believe the market is pricing in an overly long duration of today’s favorable operating conditions. Several risk factors could materially affect Quanta’s long-term performance, including how quickly industry capacity responds to demand, the duration of AI-related investment, and regulatory barriers that could slow data center development. These risks underpin our Very High Uncertainty Rating.

We are increasing our fair value estimate for Quanta Services to $410 per share from $400 to account for stronger near-term growth, but our long-term outlook remains unchanged. Our revised valuation implies a fiscal 2026 forward EV/EBITDA multiple of around 16.3 times and forward P/E multiple of 24.7 times.

We forecast the electric segment to remain Quanta’s primary growth engine, with revenue growing at a 20% compounded annual rate over the next five years before slowing to a low-double-digit pace over the following five years. We forecast operating margins to expand by 120 basis points during the first five years, with limited improvement thereafter. We believe Quanta sits at the intersection of three massive, converging trends-grid modernization, rising electricity demand, and renewable energy buildout-and is well positioned to benefit given its craft-skilled workforce and scale. Electrification should gradually lift power consumption as electricity replaces natural gas in heating and other end uses, while manufacturing reshoring in semiconductors, advanced manufacturing, and heavy industry will require substantial new power infrastructure and high-capacity grid connections. We view data centers as the most significant incremental source of demand, as accelerating AI adoption and rising computing intensity materially increase their electricity requirements. Continued renewable energy development should provide an additional tailwind, as wind, solar, and battery projects are often located far from demand centers and require new transmission infrastructure to connect them to the grid. As utilities accommodate these sources while maintaining reliability, we expect continued investment in transmission lines, substations, and broader grid infrastructure.

The underground utility and infrastructure segment is expected to remain the smaller, and gradually shrinking, portion of Quanta’s business, reflecting stronger growth opportunities in the electric segment. That said, the business should continue to benefit from natural gas utility modernization programs aimed at replacing aging cast iron, bare steel, and legacy plastic infrastructure to improve safety and reliability.

Quanta’s shares have rallied sharply in recent years as investors have increasingly viewed the company as a primary beneficiary of AI-driven data center investment and accelerating electricity demand. At the current share price, we believe the market is pricing in a prolonged period of strong revenue growth in the range of high teens to low 20s and aggressive margin expansion. Despite the current environment, we see considerable uncertainty around Quanta’s long-term revenue growth and backlog conversion. The industry has relatively low barriers to entry, particularly for smaller and less complex projects. As end market demand expands, new entrants and regional contractors may add capacity and compete for incremental work. This makes it difficult to determine how much of the broader spending opportunity will ultimately translate into maintained backlog growth for Quanta. If demand moderates or industry capacity expands too quickly, competition could intensify, pressuring both project awards and margins. As a result, we believe current end-market strength does not necessarily support the level of long-term growth implied by consensus expectations.

We don’t think Quanta Services has an economic moat. While we view the company as a leading specialty contractor in electric transmission and distribution and renewable energy services, we do not believe these advantages translate into returns on invested capital being consistently above its weighted average cost of capital. The industry remains fragmented and highly competitive, with historically volatile profitability and the potential for meaningful losses on individual projects, making it difficult for firms to generate attractive returns across the cycle.

We believe most engineering and construction firms lack economic moats due to intense competition, meaningful customer bargaining power, and the relatively standardized nature of many projects. Barriers to entry are generally low across several of the markets in which they operate, allowing adequately capitalized firms with technical expertise to compete. In addition, E&C firms face cyclical demand and execution-related risks, including labor shortages, delays in regulatory approvals, and weather-related disruptions. During end market upcycles, E&C firms can generate excess returns, but these returns are often cyclical and tend to fade as demand normalizes. While we view Quanta as more insulated from large project risk than many peers (given only about 15% of revenue is tied to large projects) many of these broader industry dynamics still apply.

The electric segment provides E&C services for electric transmission and distribution networks, substations, power generation facilities, and large load centers, alongside a smaller renewable energy business. Through a combination of acquisitions and organic growth, Quanta has built a nationwide footprint and has become the largest provider of T&D contracting services in the United States. We estimate Quanta captures roughly 10% of relevant utility spending. The renewable energy business largely consists of the company’s 2021 acquisition of Blattner Company, a leading EPC contractor for wind and solar projects. Blattner ranked as the top solar contractor in the US in 2025, having installed more than 10,000 megawatts of solar capacity.

Despite Quanta’s leading market position, we do not believe its electric segment warrants a moat. A significant portion of revenue is derived from “base” activities, including distribution line maintenance and repair, routine transmission and substation maintenance, and emergency storm restoration work. While these services are essential to grid reliability, they are generally not highly specialized and are competed for among a broad set of contractors. As a result, the market remains highly competitive, with utilities retaining the ability to switch providers with limited friction and contractors often functioning as price takers in a bid-driven environment.

There are certain areas of Quanta’s business that we view as potentially more moatworthy due to higher technical complexity and financial requirements. For example, large scale transmission projects, such as 765 kv transmission line construction, require specialized expertise and skilled labor, creating higher barriers to entry than Quanta’s base activities. Similarly, wind projects within the renewable business tend to involve greater complexity that can make bidding less competitive. In these markets, reputation and execution track records matter more, as the cost of disruptions or unscheduled downtime can far outweigh potential savings from selecting a lower cost contractor. As a result, customers may place greater emphasis on an E&C firm’s proven performance when awarding projects. However, these businesses represent only a small portion of Quanta’s operating profit, limiting their impact on the overall business.

Quanta’s underground and infrastructure segment serves customers across gas utility, oil and gas pipeline, and industrial markets. The majority of the work in this segment consists of smaller ticket activities such as gas utility system modernization, repair, and maintenance, as management has increasingly strayed away from larger pipeline projects. Much of this work is also not highly specialized and is competed for among a broad set of contractors, limiting pricing power. So, we do not believe the segment possesses a moat.

We are also concerned about the risk of material value destruction from cost overruns on fixed-price contracts for both the segments. While these contracts often carry higher margins, they also transfer the burden of unforeseen inflation, wage pressures, supply chain disruptions, labor shortages, subcontractor underperformance, weather-related disruptions, or execution delays to the E&C firm, creating the potential for significant margin erosion. Although management has since taken a more disciplined approach to project selection and risk underwriting, the company’s fixed-price contract mix has increased over the past five years. We therefore continue to view fixed-price work as an area of elevated risk, where isolated execution issues, cost overruns, or legal disputes could meaningfully pressure profitability.

Quanta is well positioned to benefit from end market tailwinds, including grid modernization, transmission buildout, and rising load growth from data centers.

The company’s sizable backlog provides strong revenue visibility in the near to medium term.

Quanta has used disciplined acquisitions to expand its addressable market and deepen exposure to faster growing end markets.

AI and data center demand may not translate into maintained growth if new entrants increase competition, permitting delays slow project execution, or electricity demand falls short of current expectations.

Ongoing shortages of skilled labor, particularly linemen and electricians, could increase costs and limit project execution capacity.

Quanta’s acquisitive growth strategy introduces execution and integration risk if deals fail to deliver expected synergies or operational benefits.
