Is Sterling the Silent Winner of America's Digital Infrastructure?

Key Takeaways
STRL's Q2 revenues rose 21% to $614.5M, with adjusted EPS up 41% to $2.69 on expanding margins.
Data centers now make up 62% of STRL's E-Infrastructure backlog, with segment revenues more than doubling.
STRL's $2B backlog and CEC acquisition boost its position as a full-service digital infrastructure partner.
Sterling Infrastructure, Inc. (STRL - Free Report) is quietly carving out a commanding role in the buildout of America’s digital backbone. The company’s second-quarter 2025 results highlighted this shift, with revenues rising 21% year over year to $614.5 million, well above expectations. Adjusted EPS surged 41% to $2.69, and margins expanded meaningfully as Sterling capitalized on mission-critical projects.
The story lies in Sterling’s E-Infrastructure Solutions segment, where demand from data centers and e-commerce facilities has exploded. Data centers now account for 62% of E-Infrastructure backlog, with revenues from that market more than doubling year over year. This concentration reflects the surge in AI, cloud and semiconductor-related investment, where speed and reliability are paramount — areas where Sterling’s project execution provides a competitive edge.
A strong $2 billion backlog, including $1.2 billion in E-Infrastructure, gives multiyear visibility. Further, the pending acquisition of CEC Facilities Group will add electrical and mechanical capabilities, strengthening Sterling’s ability to deliver end-to-end solutions. This positions the company not just as a contractor, but as a strategic partner in complex facility development.
Macro trends also favor Sterling. Rising capital expenditures by hyperscale tech firms, a pipeline of semiconductor plants and accelerating e-commerce buildouts all align with Sterling’s core strengths. Near-term housing headwinds remain a drag on its Building Solutions arm, but the company’s diversified portfolio reduces that risk.
In the race to modernize digital infrastructure, Sterling may not make headlines like the tech giants, but it’s emerging as a silent winner — one with consistent execution, expanding margins and an enviable growth runway.
Competitors in the Digital Infrastructure Race
While Sterling is making strides in data centers and e-infrastructure, it competes with industry heavyweights such as Quanta Services (PWR - Free Report) and MasTec (MTZ - Free Report) . Both Quanta Services and MasTec are well-positioned in the digital and clean energy buildout, giving them strong footholds in overlapping markets.
Quanta Services brings scale and expertise in utility and grid modernization, a critical complement to the power-hungry data centers driving demand. Quanta Services has repeatedly highlighted its role in transmission and electrification, which dovetails with Sterling’s data-center-centric growth.
MasTec continues to expand aggressively into telecommunications and renewable infrastructure. MasTec benefits from large projects in fiber and clean energy, but it is also competing for capital flowing into digital infrastructure. Like Sterling, MasTec leverages its ability to execute complex, multi-phase projects with speed and efficiency.
Together, Quanta Services and MasTec not only underline the competitive intensity Sterling must navigate but also validate the scale of opportunity in America’s digital transformation.
