Sterling Infrastructure, Inc.

What they do

Sterling builds large-scale site development and mission-critical electrical work for data centers, semiconductor fabs, manufacturing and distribution facilities through its E-Infrastructure segment. Its Transportation segment performs highway, road, bridge, airport, port, rail and storm drainage work, while Building Solutions pours residential and commercial concrete foundations, parking structures and elevated slabs and provides plumbing and survey services. The company operates primarily in the Southern, Northeastern, Mid-Atlantic and Rocky Mountain regions and the Pacific Islands.

Revenue drivers

• E-Infrastructure Solutions — Site development and mission-critical electrical services for data centers, semiconductor, manufacturing and power projects; the growth engine, with revenue up 192% in Q2 2026 and mission-critical work at 92% of segment backlog.
• Transportation Solutions — Highway, bridge, airport, port, rail and drainage work; revenue declined 20% year-over-year in Q2 2026 as resources were reallocated to E-Infrastructure, while segment adjusted operating income rose 8%.
• Building Solutions — Residential and commercial concrete foundations, parking structures, elevated slabs, plumbing and surveys; revenue fell 1% and adjusted operating income fell 11% in Q2 2026 on flat homebuilder activity.

Recent performance

Q2 2026 revenue was $1.17 billion, up 90% year-over-year, with acquisitions CEC and Stone Ridge contributing $250.8 million. Net income rose 120% to $155.8 million, or $5.00 diluted EPS, and adjusted diluted EPS was $5.80. EBITDA increased 101% to $233.6 million and adjusted EBITDA rose 104% to $256.7 million. Six-month operating cash flow was $328.0 million, and cash stood at $464.5 million at June 30, 2026. Backlog of $4.33 billion was up 116%, or 50% organically; combined backlog of $5.62 billion was up 150%.

Strategy

Sterling's stated strategy since 2016 has been to solidify its base through better risk assessment and bid discipline, grow higher-margin products and services, expand into adjacent markets, and build a platform for acquisitions. It has shifted away from low-bid heavy highway work, which fell from about 79% of total revenue in 2016 to 9% at December 31, 2025, and is winding down its Texas heavy highway business by 2026. The company is concentrating on large, time-sensitive mission-critical projects, including CEC's electrical services, and on acquisitions such as CEC and Stone Ridge.

Risks

• End-market concentration — Mission-critical projects including data centers, manufacturing and semiconductor facilities represented 92% of E-Infrastructure backlog at Q2 2026, concentrating exposure in a narrow set of end markets.
• Housing weakness — Building Solutions revenue and profit declined in Q2 2026, and management expects housing affordability pressures to keep market conditions challenging through 2026.
• Fixed-price and estimate risk — The company's over-time revenue recognition and bidding depend on cost estimates that can be affected by site conditions, contract modifications, materials, fuel, subcontractor and labor costs, and tariffs.
• Customer and cyclicality risk — Sterling depends on a limited number of significant customers and operates in a cyclical construction industry subject to economic downturns, government funding changes and interest rate fluctuations.

Outlook

Management raised full-year 2026 guidance after record Q2 results and cited a pipeline of high-probability future phase work exceeding $1.4 billion. It said signed backlog, unsigned awards and future phase opportunities give visibility into a total addressable pool of more than $7.0 billion, up more than $2.5 billion since year-end 2025. The company expects continued multi-year growth in E-Infrastructure while transportation resources shift toward that segment, and it expects Building Solutions market conditions to remain challenging through 2026.
