Here's How Much You'd Have If You Invested $1000 in Quanta Services a Decade Ago

For most investors, how much a stock's price changes over time is important. Not only can it impact your investment portfolio, but it can also help you compare investment results across sectors and industries.

The fear of missing out, or FOMO, also plays a factor in investing, especially with particular tech giants, as well as popular consumer-facing stocks.

What if you'd invested in Quanta Services (PWR) ten years ago? It may not have been easy to hold on to PWR for all that time, but if you did, how much would your investment be worth today?

Quanta Services' Business In-Depth

With that in mind, let's take a look at Quanta Services' main business drivers.

Quanta Services, Inc. is a leading provider of specialty contracting and infrastructure solutions for the electric and gas utility, power generation, large load center, manufacturing, communications, pipeline and energy industries. Quanta has operations in the United States, Canada, Australia and other selected international markets.

Starting from the first quarter of 2025, Quanta reports results under two reportable segments: Electric Infrastructure Solutions and Underground Utility and Infrastructure Solutions. The move highlights efficient allocation of resources and better management of the strategies and comprehensive solutions for its growing and increasingly converging addressable markets.

Electric Infrastructure Solutions segment (accounting for 80.8% of total 2025 revenues): This segment is the amalgamation of the previously reported Electric Power Infrastructure Solutions and the Renewable Energy Infrastructure Solutions segments. This new segment indulges in comprehensive services for the electric power, renewable energy, technology and communications markets. A few of its core services include the design, procurement, new construction, upgrade and repair and maintenance services for electric power transmission and distribution infrastructure; solar and hydropower generation facilities and battery storage facilities; and installation of “smart grid” technologies on electric power networks.

Underground Utility and Infrastructure Solutions segment (19.2%): This segment provides solutions to customers involved in the transportation of natural gas, oil and other pipeline products. Services include design, installation, repair and maintenance of oil and gas transmission and distribution systems, and related trenching and directional boring services. Also, this segment provides pipeline protection services, high-pressure and critical-path turnaround services to the downstream and midstream energy markets. 

Bottom Line

Putting together a successful investment portfolio takes a combination of research, patience, and a little bit of risk. For Quanta Services, if you bought shares a decade ago, you're likely feeling really good about your investment today.

Analysts are anticipating more upside for PWR.

Quanta reported second-quarter 2026 results, with adjusted earnings and revenues exceeding the Zacks Consensus Estimate. Both the top and bottom lines improved year over year by 41.1% and 71.0%, respectively. Its prospects are supported by rising utility and large-load spending on grid, substation and generation infrastructure. Growing electricity demand from data centers, electrification and grid modernization is driving sustained investment in power generation and mission-critical infrastructure. Record backlog and remaining performance obligations strengthen visibility, while recent acquisitions broaden electrical, mechanical, fabrication and front-end capabilities. Higher cash generation and raised 2026 guidance reinforce momentum. Shares have outperformed the industry in the year-to-date period.

Over the past four weeks, shares have rallied 6.62%, and there have been 8 higher earnings estimate revisions in the past two months for fiscal 2026 compared to none lower. The consensus estimate has moved up as well.
