Cash, debt and capacity: Year-end cash was $205.2 million. Total debt was $44.2 million, including $44.1 million of notes to former owners; there were no revolving-facility borrowings. The $850 million facility had $779.8 million available after $70.2 million of letters of credit, and expires in July 2027. The company reported compliance with its financial covenants.
Balance-sheet items: Total assets were $3.306 billion and stockholders’ equity was $1.278 billion. Current liabilities included $909.5 million of billings in excess of costs and deferred revenue, up from $548.3 million a year earlier. Receivables included a $107.1 million federal tax refund claim, which had not been received by year-end.
Backlog: $5.157 billion at year-end, up 26.9% year over year. Management expects to recognize approximately 65%–75% of remaining performance obligations over the next 12 months; backlog may be adjusted or cancelled and is not a guarantee of revenue or profit.
Material changes and notable items
- Same-store revenue rose 22.5%; acquisitions contributed a further 3.3% to revenue growth. Growth was especially strong in technology and manufacturing, including data centers and chip plants.
- Gross margin improved with higher volume, stronger project execution and improved electrical margins; growth in lower-margin modular construction partly offset the increase. SG&A rose 17.4% in dollars but declined as a share of revenue, from 11.8% to 11.0%.
- Net income benefited from operating growth but was partly offset by $23.6 million of expense from remeasurement of contingent earn-out obligations, versus $4.8 million in 2022. The 2023 effective tax rate was 16.7%, compared with a 2022 tax benefit and negative 4.3% effective rate, chiefly reflecting tax-credit and tax-settlement items.
- Operating cash flow benefited from higher pretax income, project billing timing and increased payables. The company cautioned that advance-payment benefits reverse as related project costs are incurred.
- 2023 acquisitions included Eldeco, an electrical contractor, and DECCO, a mechanical and plumbing contractor. Two additional acquisitions, Summit Industrial Construction and J&S Mechanical Contractors, closed February 1, 2024; management estimated annualized revenue contributions of approximately $375–$400 million and $145–$160 million, respectively.
- A $6.8 million pretax gain from legal developments and settlements was recorded in Q1 2023. The filing also reports a $5.1 million net gain from legal matters in 2022.
Outlook, risks and contingencies
Management expects supportive industry conditions, particularly for industrial and technology customers, to continue in 2024 and anticipates “solid earnings and cash flow,” citing advance bookings and a pipeline of opportunities. This is qualitative outlook, not quantified earnings guidance. Management expects labor cost and availability pressures to persist through 2024, while supply constraints and delivery delays are expected to continue abating.
Key risks include economic and construction-cycle weakness, competitive pricing, skilled-labor availability and cost, material price and supply disruptions, fixed-price project overruns, customer payment delays, and changes in estimates under cost-to-cost revenue accounting. The auditor identified contract cost-to-complete estimates as a critical audit matter. Other exposures include reliance on surety bonding, self-insured claims, cybersecurity threats, interest-rate risk if facility borrowings resume, and potential goodwill impairment. Management said unresolved legal matters were not material after recorded accruals, but outcomes may differ from estimates.
The financial statements received an unqualified audit opinion. Management and the auditor concluded internal control over financial reporting was effective, but Eldeco and DECCO—together 5.2% of total assets and 2.5% of revenue—were excluded from management’s year-end internal-control assessment because integration was incomplete.
Important facts for investors to verify
- Whether the strong backlog converts to profitable revenue, including project cancellations, margin trends and execution on large contracts.
- Collection timing and eventual receipt of the $107.1 million federal tax refund, alongside receivables growth and customer concentration (one customer represented 14% of 2023 revenue).
- 2024 labor and material availability, project cost estimates, and whether cash flow remains strong as advance billings are spent on project work.
- Acquisition integration, earn-out obligations and the expected contribution from the two February 2024 acquisitions.
- Potential effects of legal, self-insurance, surety and tax contingencies, and continued effectiveness of controls as acquired businesses are integrated.
*Free cash flow is a non-GAAP measure defined by the company as operating cash flow less property and equipment purchases plus sale proceeds.
