Could Sterling Infrastructure Become The US AI Data Center Buildout’s Biggest Winner?

The first phase of the artificial intelligence boom belonged to semiconductor innovators and early movers, but the second phase could provide a chance for the firms powering the AI technological buildout to shine. 

Just a glance at the scale of investments in AI can provide a glimpse into how lucrative the rollout of data centers throughout the United States will be for the firms involved in their construction and infrastructure. 

Market commentary suggests that anything between $4 trillion and $8 trillion of total capital investment will be poured into the artificial landscape over the next five years. 

What’s more is that UN researchers have forecasted that annual power demand from data centers is set to double to 945 TWh by 2030, an output that’s similar to that of the whole of Japan. The projections indicate that AI will account for 40% of the total figure. 

Given that Sterling Infrastructure (STRL) handles the physical preparation, utilities, and foundations for the construction of massive hyperscale data centers, the stock is likely to come increasingly into the spotlight throughout the AI buildout. 

Having already more than doubled in value in 2026 alone, there appears to be more to come from STRL, and the e-infrastructure stock’s market capitalization of $21 billion may prove to be cheap by the time its $5.2 billion backlog is addressed. 

Delivering the AI Infrastructure Boom

There appears to be no sign of Sterling Infrastructure’s AI-powered market rally slowing down. The company’s Q1 2026 earnings of $3.59 per share blitzed the Zacks Consensus Estimate of $2.29, while more than doubling its EPS of $1.63 from a year ago. 

The earnings surprise weighs in at +56.91%, and forecasts show that there’s likely to be plenty more growth ahead as data center buildouts begin to gather momentum. 

Demand for data centers doesn’t appear to be slowing down any time soon, with revenues surging 92% year over year over the first quarter of 2026, while adjusted EBITDA more than doubled as margins reached a record 20%. 

Critically, revenues climbed 174% on E-infrastructure as a result of strong hyperscale data center demand, semiconductor-related awards, and expanding multi-year customer programs.

As a result, Sterling Infrastructure’s backlog reached $5.2 billion, with more than $5 billion of visibility within E-infrastructure alone. 

Raised Guidance

Critically, Sterling Infrastructure appears to be on a roll. Along with its exceptionally strong Q1 report, the firm issued new full-year guidance that anticipates full-year sales to reach between $3.7 billion and $3.8 billion, a target range that far exceeds the average analyst estimate’s call for sales at $3.14 billion for the same period. 

Adjusted earnings per share have also been projected to be between $18.4 and $19.05, surpassing the average Wall Street target’s call for adjusted earnings of $13.83 per share for the year. 

One key support for Sterling’s continued growth is the fact that the AI boom is not only contributing to the firm’s massive backlog but also boosting its own operations. 

The construction landscape as a whole has benefited from artificial intelligence innovations, particularly in the quality of project management software available to firms for better efficiency and deadline management at scale. 

Sterling’s Q1 performance and considerably more optimistic forward guidance have reshaped the performance outlook for the stock, and it’s been one of the biggest contributors to the fresh wave of investor optimism that’s driving its growth on Wall Street. 

Possible Headwinds

However, it’s also worth investors noting that the stock’s price-to-earnings (P/E) ratio of 60.91x is exceptionally speculative and is likely to depend on the best-case scenario of the company addressing its sizeable order backlog in order to achieve its potential. 

Should a new competitor emerge to handle the US AI infrastructure buildout, or should the ongoing artificial intelligence boom begin to show signs of scaled-back ambitions due to new economic or geopolitical headwinds, there’s a danger that the stock will become particularly vulnerable. 

Another risk to keep in mind is the sheer scale of the E-infrastrucutre ambitions of Sterling’s clients. This could mean that the stock will be undermined by any scale-backs, cancellations, or schedule shifts throughout these multi-year projects. 

Is Sterling a Buy? 

As the artificial intelligence boom continues to enter its second phase, more stocks that are intrinsically linked to its infrastructural buildout are likely to embark on a period of growth on Wall Street. 

With a backlog of $5.2 billion already, Sterling Infrastructure is in a strong position to benefit from the AI buildout, and we can expect the stock to continue on its growth trajectory just so long as the artificial intelligence boom sustains its momentum. 

Although risks surrounding the sky-high P/E of the stock and the scale of the orders it’s set to cover could lead to headwinds should setbacks occur, Sterling has plenty of room to grow exponentially if it maintains the lion’s share of US AI infrastructure orders looking ahead.
