Construction Company Due Diligence: Financial Analysis for M&A Transactions
Construction companies challenge standard diligence frameworks. Revenue recognition depends on cost-to-complete estimates. Earnings are project-driven and lumpy. The balance sheet includes over-billings and under-billings that require careful interpretation.
For transaction services teams, construction diligence demands project-level analysis. Consolidated financial statements obscure the performance of individual projects, which is where the real risk sits.
Project-Level Revenue Analysis
Revenue recognition in construction typically follows the percentage-of-completion method, now governed by ASC 606's over-time recognition criteria. The key inputs are contract value and estimated total cost.
Cost-to-complete estimates. These are management's projections of remaining costs on open projects. The accuracy of these estimates directly determines reported revenue and gross margin. Test estimates by comparing historical cost-to-complete projections to actual outcomes.
Change orders. Approved, pending, and disputed change orders affect contract value. Assess whether pending change orders are included in revenue recognition. Unapproved change orders that are recognized in revenue represent risk.
Claims. Amounts the contractor seeks from the customer for additional work or delays. Claims recognition in revenue is aggressive and should be scrutinized.
Backlog adjustments. Contracts can be modified, terminated, or delayed. The diligence team must assess backlog quality, not just backlog size.
Each open project should be reviewed individually. A single problem project can wipe out the margin on the entire portfolio.
Backlog Quality
Backlog represents contracted but unperformed work. It is the primary indicator of future revenue, but its quality varies:
Contractual status. Signed contracts, letters of intent, and verbal agreements have different levels of certainty. Assess how the target classifies backlog.
Margin composition. Backlog weighted by expected margin reveals the profitability of future work. A growing backlog with declining margins is a warning signal.
Customer quality. Assess the creditworthiness of customers in the backlog. Construction disputes often result in payment delays or withholding.
Execution risk. Large, complex projects carry higher execution risk. Labor availability, supply chain disruptions, and weather can affect timelines and costs.
Burn rate. How quickly the backlog is being converted to revenue. Declining burn rates suggest project delays or scope reduction.
Balance Sheet Considerations
Construction balance sheets include items that require specialized analysis:
Over-billings and under-billings. Over-billings (billings in excess of costs and estimated earnings) represent cash received for unperformed work. Under-billings (costs and estimated earnings in excess of billings) represent work performed but not yet billed. The net position and trending reveal cash flow dynamics and revenue recognition aggressiveness.
Retention receivables. Amounts withheld by customers until project completion. Assess aging, collectibility, and the typical retention percentage.
Equipment and fleet. Construction companies own significant heavy equipment. Assess age, condition, utilization, and the maintenance vs. replacement capex split.
Working capital volatility. Construction working capital is highly variable. Large projects create timing differences in receivables, payables, and billings. The net working capital target must account for project-driven seasonality and volatility.
Bonding and Insurance
Surety bonding capacity is a competitive advantage and a constraint:
Bonding program. Assess the target's aggregate bonding capacity, single project limits, and relationship with surety providers. Change of ownership can trigger bonding reviews.
Bonding utilization. Current utilization relative to capacity. High utilization limits the ability to bid on new projects.
Insurance program. General liability, workers' compensation, professional liability (for design-build), and builder's risk. Review loss history, experience modification rates, and insurance costs relative to revenue.
Claims history. Outstanding claims, litigation, and dispute resolution proceedings. Construction disputes are common and can be material. The diligence team should assess each material claim individually.
Subcontractor and Labor Analysis
Construction companies depend on subcontractors and skilled labor:
Subcontractor reliance. The percentage of revenue subcontracted vs. self-performed. Heavy subcontractor reliance compresses margins but reduces fixed costs.
Labor availability. Access to skilled trades in the target's geographic markets. Labor shortages increase costs and delay projects.
Union relationships. Collective bargaining agreements, prevailing wage requirements, and benefit obligations. These affect cost structures and operational flexibility.
EBITDA Normalization
Construction EBITDA normalization requires sector-specific adjustments:
- Fade adjustments for unsustainable margins on completed projects
- Normalization for project-level gains or losses
- Equipment ownership cost adjustments (owned vs. rented fleet economics)
- Owner compensation adjustments for privately-held contractors
These adjustments should be cross-referenced with the EBITDA adjustments guide framework and supported by detailed project-level analysis. Effective normalization depends on accessing granular project data, which makes ERP data extraction particularly important in construction transactions.
Construction due diligence is project diligence. The deal team that analyzes the business at the project level, rather than relying on consolidated financials, delivers the most accurate assessment of earnings quality and deal risk.
