Sterling Infrastructure (STRL) investor relations material

Market Demand, Project Pipeline, and Strategic Overview

• No slowdowns or cancellations in advanced facility projects, with multi-year forward visibility and increasing project scale, including campuses exceeding 10,000 acres.

• Capacity constraints are anticipated, prompting longer-term planning, alliance agreements with hyperscalers, and extensive pre-construction investment.

• Even if new work stopped, existing projects would provide at least five to seven years of backlog.

• Focus on high-margin growth, strategic market expansion, and disciplined project selection, with robust balance sheet and strong cash flow supporting future growth.

• Multi-year investment trends drive growth across E-Infrastructure, Transportation, and Building Solutions, with strong demand in data centers, semiconductor, and e-commerce infrastructure.

Labor and Resource Challenges

• Labor shortages, especially for electricians, are a significant bottleneck, with a four-year window before new journeymen enter the workforce.

• Modular and prefabrication strategies are being expanded to offset labor constraints, saving 15%-20% in cost and labor.

• Higher wages and longer project durations are attracting electricians from smaller firms, but this may deplete the pool for smaller businesses.

• Immigration reform is seen as necessary to address skilled labor shortages.

• Labor fungibility means all advanced facility types will compete for the same skilled trades, intensifying competition.

Business Model, Backlog, and Project Selection

• Projects are phased, reducing risk and allowing for pricing adjustments, but much future work is not reflected in reported backlog.

• Selectivity in project acceptance is high, focusing on margin growth and cash flow, with willingness to shift between end markets.

• Backlog reached $4.3 billion as of June 30, 2026, with combined backlog visibility to $5.6 billion and strong bid activity continuing.

• Operating cash flow exceeded $1.7 billion since the beginning of 2023, providing flexibility for growth investments.

• 100% completion rate on projects once started, with recent expansion into new campuses.
