Sterling's Digital Infrastructure Expansion Surges Forward: Are Data Centers Ready to Meet the Demand?

Sterling Infrastructure’s Rapid Expansion

Sterling Infrastructure, Inc. (STRL) has seen remarkable growth, especially within its E-Infrastructure Solutions division, which is benefiting from the surging demand in the data center sector. In the fourth quarter of 2025, revenue from E-Infrastructure soared by 123% compared to the previous year. For the entire year, the segment’s revenue climbed 59%, with organic growth accounting for 40%. This robust performance highlights Sterling’s strategic emphasis on high-priority projects, including data centers, semiconductor plants, and advanced manufacturing facilities.

The division’s backlog of signed contracts reached unprecedented levels, up 79% from the end of 2024. A major driver behind this was the acquisition of CEC Facilities Group in September 2025, which alone contributed $129.1 million to Sterling’s fourth-quarter revenue. CEC’s own fourth-quarter revenue increased 21% year-over-year. The acquisition also boosted Sterling’s backlog, adding about $488.9 million in signed contracts and $715.2 million in total backlog, which includes both signed and unsigned deals.

Leadership at Sterling sees the current environment as part of a long-term infrastructure expansion, fueled by hyperscale cloud providers and the growing need for AI-driven computing. Sterling is broadening its reach into fast-growing areas like Texas and the Pacific Northwest, while enhancing its electrical capabilities through acquisitions and modular construction. For 2026, the company has set an ambitious target for E-Infrastructure revenue growth of at least 40%, supported by a combined pipeline of signed, unsigned, and future phased projects exceeding $3 billion.

As data center projects become more extensive and complex, Sterling’s integrated approach—combining site development, electrical work, and infrastructure expertise—positions it to secure a larger share of these essential builds. The main challenge ahead is whether the pace of data center development will remain strong enough to sustain Sterling’s rapid growth in E-Infrastructure.

Competitive Landscape

Sterling competes in the infrastructure construction sector alongside major players like MasTec, Inc. (MTZ) and EMCOR Group, Inc. (EME).

• MasTec is a diversified engineering and construction firm with significant involvement in communications, power delivery, and energy infrastructure. The company supports data center expansion through transmission, distribution, and fiber deployment, ensuring power and connectivity. Its broad portfolio and scale help maintain steady project flow during periods of increased infrastructure investment.
• EMCOR specializes in electrical and mechanical construction and services, with substantial exposure to mission-critical facilities such as data centers, semiconductor plants, life sciences, and energy infrastructure. While data centers are a key growth area for EMCOR, they are just one part of its diverse commercial and industrial market presence.
