The stock has outperformed some other players, including AECOM (ACM - Free Report) , Fluor Corporation (FLR - Free Report) and KBR, Inc. (KBR - Free Report) . In the past three months, AECOM and KBR have rallied 7.6% and 8%, respectively, while Fluor has gained 6.5%. Let us take a closer look at the factors shaping Sterling stock’s prospects.
Sterling continues to benefit from rising demand for mission-critical construction projects. The company’s E-Infrastructure Solutions segment is seeing strong activity from data centers, manufacturing facilities and semiconductor developments, which require extensive site development and electrical infrastructure.
This momentum supported strong quarterly results. E-Infrastructure revenues increased 123% year over year in the fourth quarter, including 67% organic growth. Data center construction remained the primary growth driver as hyperscalers and technology companies accelerated infrastructure investments. With projects becoming larger and spanning longer development timelines, Sterling appears well positioned to capitalize on sustained demand across mission-critical markets.
Sterling Entered 2026 With a Strong Backlog Position
Sterling entered 2026 with a significantly stronger backlog, providing clear visibility into future revenues. Signed backlog totaled $3 billion at year-end 2025, reflecting a 78% increase from the prior year. When combined with unsigned awards of $301 million and more than $1 billion of future phase opportunities, the company now has visibility into a potential work pool approaching $4.5 billion.
Much of this future phase work is tied to projects already underway with existing customers. As these projects progress, additional work packages are expected to be released, providing steady revenue opportunities. With strong project visibility and a deep pipeline of mission-critical work, Sterling appears well positioned to sustain growth in the coming years.
Data Center Expansion Strengthens Sterling’s Growth Platform
Rising investments in digital infrastructure remain a major growth catalyst for Sterling. The company highlighted that data center developments are becoming significantly larger, often evolving into multi-building campuses that require extensive infrastructure development.
These projects demand significant site preparation, utilities and electrical work, areas where Sterling has strong execution capabilities. The company is also expanding its presence in key data center markets such as Texas and the Southeast. As hyperscale operators continue to expand computing capacity and artificial intelligence infrastructure, data center construction is expected to remain a key driver of Sterling’s long-term growth.
Sterling’s Transportation Solutions segment continues to benefit from steady infrastructure activity and healthy project awards. In the fourth quarter, the business delivered solid performance supported by strong bidding activity and the conversion of previously unsigned projects into signed contracts.
The company ended the quarter with a Transportation Solutions backlog of $1.1 billion, reflecting an 81% year-over-year increase. The growth was driven by strong award activity and the conversion of previously unsigned backlog into signed contracts. Looking ahead, management expects continued bid activity as the current federal infrastructure funding cycle runs through September 2026.
With more than two years of backlog already built and steady demand in core markets such as the Rocky Mountain region, the Transportation Solutions segment is expected to remain a stable contributor to Sterling’s growth. Management expects Transportation Solutions revenues to grow in the low to mid-single-digit range in 2026, along with continued margin expansion.
