In Q3 2025, Sterling Infrastructure’s Transportation Solutions segment posted a 10% revenue gain and 40% growth in adjusted operating profit, lifting margins 335 basis points to 15.6%. The unit ended the quarter with a $733 million backlog (up 23%) and sees 13.5%–14% operating margins for 2025.
1. Strong Third-Quarter Margin Rebound
Sterling’s Transportation Solutions segment delivered a 10% year-over-year revenue increase in Q3 2025, while adjusted operating profit rose 40%, driving margins up 335 basis points to 15.6%. This performance reflects improved execution and a shift toward higher-margin technical and design-build projects.
2. Structural Shift in Project Mix
Management is winding down its low-bid heavy-highway business in Texas, which has slightly reduced near-term backlog but is expected to enhance profitability as lower-margin contracts complete by mid-2026. At the same time, disciplined project selection, portfolio optimization and experienced teams are limiting rework and schedule overruns.
3. Backlog Growth and Outlook
The segment closed Q3 with a $733 million backlog, up 23% year-over-year, providing over two years of revenue visibility. Sterling forecasts full-year Transportation operating margins of 13.5%–14% for 2025, up from 9.6% in 2024, positioning the business for more stable, profitable growth if federal infrastructure funding continues as planned.
