Key Financial Metrics (Fiscal Year 2025)

Material Changes vs. Prior Period

• Revenue Growth: Consolidated revenue increased $115.8 million, driven by higher construction management revenues, increased demand for energy efficiency/electrification services, and incremental revenue from acquisitions (Enica, APG, Alpha).
• Margin Expansion: Gross margin improved to 37.5% from 35.8% in 2024 due to a favorable mix of revenues and cost controls. Operating margin rose to 6.5% from 5.5%.
• Profitability Surge: Net income more than doubled to $52.6 million. This was driven by higher operating income and a significant tax benefit of $12.6 million (effective tax benefit rate of 31.4%), compared to a tax expense of $4.1 million in 2024. The tax benefit was largely due to discrete items including stock compensation deductions and energy-efficiency building deductions.
• Acquisitions: Completed three acquisitions in FY2025: Alternative Power Generation, Inc. (APG), Alpha Inspections, Inc., and Compass Municipal Advisors, LLC. These contributed $30.4 million in revenue and $3.4 million in operating income.
• Debt Restructuring: Entered into an Amended and Restated Credit Agreement in May 2025, extending maturity to 2030 and increasing the Revolving Credit Facility to $100 million. The company paid down its prior credit agreement and currently has $48.8 million outstanding on a Term Loan.

Guidance, Outlook, and Risks

Outlook & Commentary: Management expects continued growth driven by the transformation of the energy and infrastructure environments, including electrification, AI data center load growth, and climate change adaptation. The company maintains a strategy of organic expansion and strategic acquisitions.

Key Risks:

• Customer Concentration: Top 10 customers accounted for 50.7% of revenue. Two customers (Clark County School District and Southern California Edison) accounted for 23.2% of consolidated revenue in FY2025.
• Contract Termination: Most contracts allow clients to terminate for convenience, creating uncertainty in backlog realization.
• Fixed-Price Risks: 47% of revenue is from fixed-price contracts, exposing the company to cost overruns, supply chain constraints, and labor shortages.
• Regulatory Dependence: Demand is heavily influenced by state and local utility regulations and government budgets.
• Acquisition Integration: Risks associated with integrating recent acquisitions and realizing expected synergies.

Investor Verification Checklist

• Tax Rate Sustainability: Verify the sustainability of the 31.4% effective tax benefit rate, which was driven by discrete items (stock comp windfalls and Section 179D deductions) that may not recur at the same magnitude.
• Customer Concentration: Monitor the status of contracts with Clark County School District and Southern California Edison, which represent a significant portion of revenue.
• Backlog Realization: Assess the quality of the $1.0 billion backlog, noting that a portion is subject to termination for convenience and may not be fully realized.
• Acquisition Performance: Track the financial performance of APG, Alpha, and Compass to ensure they meet earn-out targets and integration goals.
• Debt Covenants: Confirm continued compliance with the new Credit Agreement covenants (Net Leverage Ratio and Fixed Charge Coverage Ratio).
