    Soft market conditions in Building Solutionsnear term (2026)

    Q4 revenue declined 9%; FY25 revenue declined 6%; FY26 revenue expected to decline high single to low double digits.

    Mitigation: Diversified portfolio and strategy to focus on growth in high-margin end markets. Opportunity for share gain coming out of a down cycle.

    Affordability challenges impacting home demand2026

    Building Solutions revenue decline

    Mitigation: Key geographies (Dallas Fort Worth, Houston, Phoenix) expected to see population growth driving new home demand. Expect to pick up market share coming out of the downturn.

    Residential market inventory post-turnaroundafter market turnaround

    3-4 months of inventory on the ground

    Mitigation: Acknowledged as a factor that will delay new builds even after market conditions improve.

    Texas E-Infrastructure Awards

    Q1 2026
    CurrentActively working and winning jobs
    TargetAnnouncement of 'very nice awards'

    Why it matters

    Confirms successful geographic expansion and integration of CEC, driving E-Infrastructure growth in a key market.

    I think in the first half of this year, we're going to be able to talk about some very nice awards that take place in Texas.

    Q&A highlights

    10

    Transportation backlog was stronger than expected. Were there any large awards or notable call-outs?

    No single large project, but consistent good bid activity. Only 50-60% of the current funding cycle has been spent, and projects continue to be let. The end of the funding cycle is not a 'toggle switch'; extensions adjusted for inflation are common.

    “Nothing in particular. There wasn't one big giant project or anything. I think what people tend to get confused with is even though we're coming to the end of a funding cycle, only about 50% to 60% of the total funding has been spent.”

    Detailed Narrative

    01

    E-Infrastructure Growth & Expansion

    Sterling's E-Infrastructure segment demonstrated robust performance, with Q4 revenue growing 123%, including 67% organic growth, primarily driven by the data center market. The Rocky Mountain site development operation, focused on mission-critical work, grew over 150% year-over-year. The company is actively pursuing geographic expansion, particularly into Texas and the Pacific Northwest, pulled by customer demand for larger, longer-duration mission-critical projects.

    02

    Texas Market Focus

    The Texas market is a significant growth area, described as "on fire," with substantial opportunities for both electrical and site development services. The CEC acquisition is performing well, with its Q4 revenue increasing 21% year-over-year. Sterling is strategically attacking the Texas market from both East (Dallas/Houston corridor) and West (using Rocky Mountain resources) and is seeking strategic acquisitions within the state to enhance assets, resources, and capacity.

    03

    Backlog & Pipeline Strength

    The company ended Q4 FY25 with a record signed backlog of $3 billion, representing a 78% increase year-over-year (50% on a same-store basis). When combined with $301 million in unsigned awards and over $1 billion in future phase opportunities, Sterling has visibility into approximately $4.5 billion of work. Mission-critical projects, including data centers, large manufacturing, and semiconductors, constitute 84% of the E-Infrastructure signed backlog.

    04

    Semiconductor & Manufacturing Outlook

    Sterling anticipates a significant wave of mega projects in the semiconductor and manufacturing sectors later in the decade, with some awards expected in 2026. These projects are considerably larger than typical data center jobs, with semiconductor plants potentially spanning 7-10 years and total scopes approaching $1 billion. The company notes a 3-5 year lead time from announcement to groundbreaking for such facilities due to permitting and equipment procurement.

    05

    Modular Construction & AI Adoption

    To enhance productivity and margins, Sterling is tripling the size of CEC's modular build facility to over 300,000 square feet, enabling more prefabrication of components like exterior piping, conduit, duct banks, and cabinets. Additionally, the company is actively leveraging AI in its operations, with 6 projects underway. Initial pilots demonstrated a 15-20% increase in project manager capacity, improving efficiency, effectiveness, quality, and safety.

    06

    Residential Market Headwinds

    The Building Solutions segment continues to face challenges due to affordability issues impacting new home demand. Full year 2025 revenue declined 6%, and Q4 revenue was down 9% with adjusted operating margins at 10%. Management expects these soft market conditions to persist, projecting a high single to low double-digit revenue decline for Building Solutions in 2026, with margins remaining in the low double digits.
