Sterling Infrastructure, Inc. (STRL - Free Report) is gaining from robust data center–related site development and mission-critical projects, which are operated through its E-Infrastructure Solutions segment. These projects comparatively carry structurally higher margins due to their complexity, tighter timelines and the premium customers place on execution certainty. During the third quarter of 2025, revenues from the data center market grew year over year by a whopping 125%, with the E-Infrastructure segment’s revenues increasing 58% (including the CEC acquisition).
Management has emphasized that Sterling’s project selection discipline and focus on negotiated or repeat-customer work, rather than low-bid contracts, are central to protecting margins even as volumes rise. Besides, the company is additionally benefiting from standardized processes, strong cost controls and experienced project teams that limit rework and schedule overruns. This execution advantage has allowed STRL to scale revenues while still expanding margins, rather than facing the typical dilution that accompanies rapid growth in construction.
Notably, the CEC acquisition, closed in the third quarter of 2025, is catalyzing Sterling’s growth prospects as this buyout expands its electrical capabilities that complement site development work, increasing self-perform content and cross-selling opportunities, both of which are margin-accretive over time.
Although a large project scale can introduce complexity, labor availability constraints and competitive intensity in data center infrastructure, STRL’s strong visibility in high-margin end markets and efficient execution are encouraging for the near and long-term growth. Thus, it can be highlighted that Sterling appears well-positioned to defend margins near the 25% level in the upcoming period.
