Sterling Infrastructure, Inc. STRL delivered a strong second quarter of 2026, with adjusted earnings and revenues topping the Zacks Consensus Estimate and increasing sharply year over year. Results were driven by outsized growth in E-Infrastructure Solutions, supported by strong organic execution and contributions from the CEC and Stone Ridge acquisitions.
Transportation Solutions revenues declined as Sterling accelerated the reallocation of resources toward higher-margin E-Infrastructure opportunities. Meanwhile, Building Solutions remained pressured by relatively flat homebuilder activity and continued housing affordability challenges.

Q2 Segmental Discussion of Sterling
E-Infrastructure Solutions was the primary growth engine, with segment revenues, which accounted for 78% of total revenues, jumping to $905 million from $310.4 million in the year-ago quarter. Management attributed the performance to strong results across organic and acquired operations. The legacy site development business generated 111% revenue growth, reflecting expansion across all regions, while CEC’s electrical services revenues increased 140% from the pre-acquisition second quarter.

E-Infrastructure signed backlog rose 165% year over year, with mission-critical projects, including data centers, manufacturing and semiconductor facilities, representing 92% of segment backlog.
Transportation Solutions revenues, which represented 13% of total revenues, declined to $156.7 million from $196.8 million. The decrease reflected Sterling’s ongoing shift of resources from transportation projects toward higher-margin E-Infrastructure opportunities.

Building Solutions remained the softer spot. Revenues, which accounted for 9% of total revenues, slipped to $106.5 million from $107.3 million. Adjusted operating income declined to $10.5 million from $11.8 million as relatively flat homebuilder activity and affordability pressures weighed on performance.
