Factors Likely to Shape STRL’s Q3 Performance

Sterling is likely to have maintained its growth momentum in the third quarter of 2025. The company continues to benefit from its focus on high-margin markets, such as data centers, e-commerce distribution and manufacturing facilities. Expansion into new geographies and steady transportation activity are expected to have supported growth during the quarter. Strategic acquisitions, including CEC Facilities Group, are expected to have strengthened service capabilities and customer reach. A healthy project pipeline and a strong backlog are likely to have provided multi-year visibility.

Segment-wise, E-Infrastructure Solutions (which accounted for 51% of second-quarter 2025 revenues) is expected to have remained the key growth driver in the to-be-reported quarter. The segment is likely to have benefited from robust demand in data center development, driven by ongoing AI and digital transformation trends. Expansion into new markets such as Texas and early activity in the Northwest are expected to have supported growth. 

Rising e-commerce distribution and manufacturing projects might have added further momentum. The segment is also likely to have gained from consistent bid activity and visibility into multi-phase projects. The Zacks consensus Estimate for E-infrastructure Solutions revenues for the to-be-reported quarter is pegged at $349 million, up from $264 million reported a year ago.

The Transportation Solutions segment (which accounted for 32% of total second-quarter 2025 revenues) is expected to have delivered steady performance in the third quarter. Growth is likely to have been supported by solid backlog levels and sustained federal funding under the IIJA program. Continued demand in key markets, including the Rocky Mountain and Arizona regions, might have driven activity. 

The planned downsizing of low-bid heavy highway operations in Texas is expected to have moderated revenues but supported margin improvement through a more profitable mix. The consensus mark for Transportation Solutions revenues is pegged at $170 million, reflecting a decrease of 25.1% year over year.

Sterling’s Building Solutions segment (which accounted for 17% of total second-quarter 2025 revenues) is expected to have faced mixed conditions in the to-be-reported quarter. Elevated mortgage rates and affordability pressures might have continued to weigh on residential demand. However, steady construction activity in key markets such as Dallas, Fort Worth, Houston and Phoenix is expected to have supported volumes. 

The company’s efforts toward service diversification and operational discipline are likely to have offset part of the softness in the housing market. The consensus mark for Building Solutions revenues is pegged at $96 million, implying a decrease of 6.8% year over year.
    
From the margin perspective, Sterling is expected to have benefited from its growing mix of large-scale, complex projects. Execution efficiency and a disciplined approach to project selection are likely to have supported higher profitability. The company’s continued shift toward mission-critical infrastructure work, especially in the data center and industrial markets, is expected to have contributed to margin resilience in the quarter.
