- Margin Expansion: Gross margin improved significantly to 23.3% in Q2 2025 from 19.3% in Q2 2024, driven by higher volume in E-Infrastructure and improved project mix.

- Transportation: Revenue down 15.5% reported, but up 23.9% excluding RHB; Operating margin improved to 13.2%.
- Building Solutions: Revenue down 1.4% due to residential market slowdown; Operating margin declined to 9.2%.

Growth is expected in E-Infrastructure (data centers/manufacturing) and Transportation (federal funding), while Building Solutions faces near-term headwinds from housing affordability.

Investor Verification Checklist
- RHB Deconsolidation Impact: Verify the specific impact of removing RHB revenue ($73.9M in Q2) on year-over-year growth calculations to assess true organic performance.
- CEC Acquisition Financing: Confirm the funding sources for the $450M cash portion of the CEC acquisition and its impact on future leverage ratios.
- Building Solutions Trend: Monitor the duration of the residential market slowdown and its effect on the Building Solutions segment margin.
- Contract Estimates: Review the $42M (Q2) and $72M (YTD) revenue increases from changes in contract estimates to ensure they are sustainable and not one-time adjustments.
- Debt Covenants: Confirm continued compliance with the amended credit facility covenants, particularly regarding leverage and interest coverage.
