Key Financial Metrics

Material Changes vs. Prior Period

• Revenue Growth: Revenue increased 50.3% in Q2 2026 and 53.1% for the six months ended June 30, 2026, compared to the prior year. Growth was driven by a 43.8% same-store increase and acquisitions (R.C. Hunt Electric, Feyen-Zylstra, Meisner Electric, and Right Way Plumbing).
• Margin Expansion: Gross margin improved from 23.5% to 25.9% in Q2, and operating margin expanded from 13.8% to 17.1%. This was attributed to improved execution, favorable change orders, and revenue leverage over SG&A expenses.
• Segment Performance: The Electrical segment saw an 81.2% revenue increase in Q2, while the Mechanical segment grew 40.2%. Both segments benefited significantly from demand in the technology sector, particularly data centers.
• Cash Flow: Net cash provided by operating activities surged to $1.53 billion for the six months ended June 30, 2026, compared to $164.5 million in the prior year period, driven by higher earnings and timing of billings/payments.
• Acquisitions: Completed the acquisition of R.C. Hunt Electric in May 2026 for a preliminary price of $206.0 million.

Guidance, Outlook, and Risks

• Outlook: Management expects high ongoing demand and solid earnings for the remainder of 2026, particularly in manufacturing and technology sectors. They anticipate continued labor cost increases and intermittent supply chain shortages.
• Backlog: Backlog increased 73.1% year-over-year to $14.06 billion. The company expects to recognize 65-75% of remaining performance obligations over the next 12 months.
• Liquidity: The company maintains a $1.10 billion revolving credit facility with $1.01 billion available as of June 30, 2026. No borrowings were outstanding on the facility at period end.
• Risks: Key risks include labor shortages, material cost inflation, supply chain delays, potential economic downturns affecting construction activity, and the ability to successfully integrate acquisitions. The company is self-insured for significant liabilities, creating exposure to loss estimates.
• Tax Matters: The effective tax rate for the six months ended June 30, 2026, was 22.5%, impacted by state taxes and R&D credits. A $29.8 million tax refund was received in July 2026 related to prior years.

Investor Verification Checklist

• Backlog Conversion: Verify the rate at which the record $14.06 billion backlog converts to revenue in subsequent quarters, given the 65-75% recognition expectation.
• Margin Sustainability: Monitor whether the improved gross and operating margins (25.9% and 17.1% respectively) can be sustained amidst rising labor costs and supply chain pressures.
• Technology Sector Exposure: Assess the concentration risk in the technology sector (58.7% of Q2 revenue), specifically regarding data center projects, and potential volatility in this end-market.
• Acquisition Integration: Track the financial performance and integration progress of recent acquisitions (Hunt, Feyen-Zylstra, Meisner) to ensure they meet earn-out targets and contribute to organic growth.
• Working Capital Management: Review the significant increase in "Billings in excess of costs" ($3.23 billion) and receivables to ensure cash collection remains robust as project volumes scale.
