Key Takeaways:
- Quanta Services is the largest specialty contractor in the U.S., building and maintaining the electric power infrastructure, natural gas pipelines, and telecom networks that AI data centers and modern utilities depend on.
- PWR stock could reasonably reach around $929 per share by late 2028, based on our valuation assumptions.
- This implies a total return of around 19% from today’s price of $780, with a 6.8% annualized return over the next 2.6 years.
What Happened?
Quanta Services (PWR) has been one of the standout performers in the market over the past 12 months. The stock surged 127% in that period, fueled by the explosive growth in AI data center construction and the resulting surge in U.S. power grid investment.
Q1 fiscal 2026 results were well above expectations, with adjusted EPS of $2.68 versus the $2.06 analyst estimate. Revenue reached $7.9 billion for the quarter, and diluted EPS grew 51% year over year.
Management raised its 2026 profit forecast, directly citing robust demand from AI data centers driving urgent electricity grid upgrades. The company also hosted a major investor day in March 2026, where it unveiled long-term financial targets and growth plans.
Quanta was also awarded a $1.7 billion share of the Grain Belt Express transmission line project, one of the largest power infrastructure contracts in recent years. Analysts from Bernstein, Mizuho, BMO, and Citi all raised their price targets following the strong results.
Quanta’s core business serves utility companies building and upgrading electrical transmission and distribution infrastructure across North America. It also builds renewable energy interconnections, data center power supply networks, and natural gas pipelines.
The AI boom has created urgent new demand for power infrastructure, and Quanta is one of the few companies large enough to execute these projects at scale. Its market capitalization has now grown to around $117 billion.
However, the stock now sits near its 52-week high of $789, and the consensus analyst price target of $748 is actually slightly below the current price. That tells investors the stock may already reflect near-term expectations in full.
Here’s why Quanta Services stock could still deliver additional gains through 2028 as the multi-year power infrastructure spending cycle remains intact.
What the Model Says for PWR Stock
We analyzed the upside potential for Quanta Services stock based on the multi-year buildout of U.S. power grid infrastructure, robust AI data center electricity demand, and Quanta’s dominant position as the largest specialty electrical contractor in North America.
Based on estimates of around 17% annual revenue growth, 7% operating margins, and a normalized P/E multiple of 41.1x, the model projects Quanta Services stock could rise from $780 to around $929 per share.
That would be a 19% total return, or a 6.8% annualized return over the next 2.6 years.
Our Valuation Assumptions
TIKR’s Valuation Model lets you plug in your own assumptions for a company’s revenue growth, operating margins, and P/E multiple, and calculates the stock’s expected returns.
Here’s what we used for PWR stock:
1. Revenue Growth: 16.8%
Quanta’s Q1 fiscal 2026 revenue reached $7.9 billion, and diluted EPS grew 51% year over year. Management raised its full year 2026 profit forecast immediately after the quarter, citing AI data center demand as the primary growth driver.
The company also secured a $1.7 billion share of the Grain Belt Express transmission line contract, and demand from utilities, renewable energy developers, and AI hyperscalers continues to grow rapidly. Quanta also unveiled long-term financial targets at its March 2026 investor day, pointing to continued strong growth ahead.
Based on analysts’ consensus estimates, we used around 17% annual revenue growth. This reflects Quanta’s strong execution track record and the multi-year infrastructure spending cycle driven by AI adoption and the broader U.S. energy transition.
2. Operating Margins: 7%
Quanta’s LTM gross margin is 15.1%, and its LTM EBIT margin is 5.6%. These margins are lower than those of software companies but are consistent with a labor-intensive specialty services business with strong contract pricing power.
The company has consistently improved margins by shifting to larger, more complex, and higher-margin projects. As AI infrastructure spending ramps and Quanta’s project mix continues to shift upmarket, further margin improvement looks achievable.
Based on analysts’ consensus estimates, we used 7% operating margins. This reflects modest improvement from current LTM EBIT levels as revenue scales and the project mix tilts toward larger infrastructure programs.
3. Exit P/E Multiple: 41.1x
Quanta currently trades at an NTM P/E of 54x, which reflects investor enthusiasm for the AI infrastructure buildout. That multiple has expanded sharply as the stock surged 127% over the past 12 months.
The exit P/E of 41.1x assumes some compression as the stock’s valuation normalizes after its historic run. But it still reflects a premium multiple, consistent with Quanta’s market leadership and the quality of its long-term contract backlog.
Based on analysts’ consensus estimates, we used a 41.1x exit P/E multiple. This reflects a moderate pullback from current elevated levels, but still prices Quanta as a premier infrastructure company benefiting from a generational spending cycle.

What Happens If Things Go Better or Worse?
Different scenarios for PWR stock through 2030 show varied outcomes based on AI data center power demand and U.S. grid investment levels (these are estimates, not guaranteed returns):
- Low Case: AI power demand moderates and project backlogs soften, with around 12% revenue CAGR → around 7% annual returns
- Mid Case: AI infrastructure investment stays robust, and grid upgrade spending accelerates further, with around 13% revenue CAGR → around 11% annual returns
- High Case: Power demand significantly exceeds forecasts, and Quanta wins major new multi-billion contracts, with around 14% revenue CAGR → around 14% annual returns
Going forward, Quanta Services is well-positioned to benefit from what appears to be a generational upgrade cycle in U.S. power infrastructure driven by AI and the energy transition. The long-term mid case projects around 11% annual returns through 2030, which is modestly attractive given Quanta’s dominant market position.
But investors should be aware that the stock already trades near its all-time high, and the consensus analyst target now sits slightly below the current price.
