Read MoreHide Full Article
Key Takeaways
STRL's E-Infrastructure revenue rose 18%, with adjusted margins expanding over 600 bps to reach 23%.
AI-fueled data centers now make up 65% of STRL's e-infrastructure backlog, driving execution momentum.
STRL posted 29% EPS growth and ended Q1 with a $1.2B backlog and nearly $2B in future-phase visibility.
Sterling Infrastructure, Inc. (STRL - Free Report) is capitalizing on a powerful surge in e-infrastructure demand, delivering a standout first quarter in 2025. The company reported an 18% year-over-year revenue increase in its E-Infrastructure Solutions segment, with adjusted operating income surging 61% and margins expanding by more than 600 basis points to 23%. This growth is largely fueled by rising investments in AI-driven data centers, which now make up more than 65% of Sterling’s e-infrastructure backlog. Strong project execution and the ability to finish mission-critical projects ahead of schedule have helped Sterling deepen relationships with large customers, reinforcing its competitive position.
On the financial front, Sterling posted adjusted earnings per share (EPS) of $1.63, up 29% year over year, and adjusted EBITDA rose 31% to $80 million. The company ended the quarter with a record $1.2 billion in e-infrastructure backlog and future-phase visibility nearing $2 billion, a milestone reflecting both demand strength and Sterling’s execution capabilities. Sterling’s exposure to onshoring trends, such as semiconductor and biopharma facility construction, further amplifies its growth runway. The company’s phase-by-phase pricing model also minimizes risk from raw material and fuel cost fluctuations, helping preserve margins even amid volatility.
Looking ahead, management expects mid-to-high teens revenue growth for the E-Infrastructure segment in 2025, with adjusted operating margins continuing in the mid-20% range. Backed by structural trends in AI, e-commerce, and digital infrastructure, Sterling appears well-positioned to sustain its upward trajectory as the e-infrastructure boom gains speed.
How Sterling Competes in the Infrastructure Boom
As Sterling rides the e-infrastructure wave, it faces competition from peers also targeting high-growth sectors like data centers, semiconductors, and transportation buildouts. Two notable players in this space are Quanta Services (PWR - Free Report) and EMCOR Group (EME - Free Report) .
Quanta Services, a leader in specialty contracting for power and infrastructure, has aggressively expanded into data center development and grid modernization. With deep expertise in electric power and network systems, Quanta Services is benefiting from rising AI energy needs and utility-scale connectivity, areas that overlap increasingly with Sterling’s growth zones.
EMCOR, on the other hand, brings strong capabilities in mechanical and electrical construction, particularly in mission-critical environments like health care, semiconductor fabs, and advanced manufacturing. EMCOR’s emphasis on integrated infrastructure solutions mirrors Sterling’s push into turnkey E-Infrastructure projects.
While Sterling boasts superior margins and backlog momentum, both Quanta Services and EMCOR offer broader national footprints and diversified customer bases, keeping competitive pressure intense in this expanding market.
