Due Diligence Checklist for Acquiring a Transportation Business

What every buyer must verify before closing on a trucking, freight, or last-mile delivery company in the lower middle market.

Find Transportation Acquisition Targets

Acquiring a transportation business requires evaluating hard assets, regulatory standing, and workforce stability simultaneously. Fleet condition, DOT safety ratings, and customer concentration are the three factors most likely to surface material deal risk in trucking acquisitions under $5M revenue.

Transportation Due Diligence Phases

01

Phase 1: Financial & Revenue Quality

Assess the sustainability and quality of earnings before valuing the business or structuring an offer.

Normalize 3 Years of Financial Statementscritical

Recast owner compensation, personal vehicle expenses, and discretionary costs to calculate true EBITDA. Verify accrual-basis accounting and reconcile with tax returns.

Analyze Customer Concentrationcritical

Identify revenue by client. Flag any single customer exceeding 25–30% of total revenue. Request contract terms, renewal history, and rate escalation clauses.

Review Fuel Surcharge and Freight Rate Mechanismsimportant

Confirm whether fuel surcharges are contractually passed through to customers. Assess rate lock-in periods and margin compression risk during fuel price spikes.

02

Phase 2: Regulatory & Compliance Review

Verify the company's standing with FMCSA, DOT, and relevant state regulators before proceeding to LOI or final diligence.

Pull DOT Safety Rating and CSA Scorescritical

Obtain current FMCSA safety rating and review all seven CSA Behavior Analysis categories. Unresolved violations or a Conditional/Unsatisfactory rating are serious red flags.

Audit Insurance History and Open Claimscritical

Request 5 years of loss runs from current carrier. Identify open cargo, liability, or workers' comp claims that could transfer as undisclosed liabilities post-close.

Review Driver Classification and CDL Complianceimportant

Confirm all drivers hold valid CDLs with proper endorsements. Identify independent contractor arrangements that may not meet IRS or DOL classification standards.

03

Phase 3: Fleet & Operational Assessment

Evaluate the physical asset base, dispatch infrastructure, and operational dependencies before finalizing deal structure.

Conduct Full Fleet Inspection and Capex Analysiscritical

Verify age, mileage, and maintenance history for every unit. Estimate near-term replacement costs for trucks exceeding 7 years or 500K miles to model true acquisition cost.

Assess Dispatch Systems and SOPsimportant

Determine whether routing, dispatch, and customer communication rely on documented systems or solely on the owner. Undocumented processes increase transition and retention risk.

Review Driver Roster Stability and Turnover Historyimportant

Request 2-year driver turnover data. High churn signals cultural or compensation problems that could destabilize operations immediately post-acquisition.

Transportation-Specific Due Diligence Items

  • Verify IFTA fuel tax filings and state apportioned registration compliance for all jurisdictions the fleet operates in.
  • Confirm ELD mandate compliance across the entire fleet and review HOS violation history in the FMCSA portal.
  • Assess whether any dedicated lane agreements or freight contracts contain change-of-control clauses that could trigger renegotiation at close.
  • Review any hazmat, refrigerated, or specialized equipment certifications required to service key accounts and confirm transferability.
  • Obtain a title search and UCC lien report on all fleet assets to identify existing equipment financing obligations that affect net asset value.

Frequently Asked Questions

What EBITDA multiple should I expect to pay for a small trucking company?

Lower middle market transportation businesses typically trade at 3x–5.5x EBITDA. Cleaner DOT records, modern fleets, and diversified customer contracts support multiples at the higher end of that range.

Can I use an SBA loan to acquire a transportation business?

Yes. SBA 7(a) loans are commonly used for trucking acquisitions. Lenders will scrutinize fleet collateral value, DOT compliance history, and customer contract stability when underwriting transportation deals.

What is the biggest due diligence risk in buying a freight or trucking company?

Customer concentration and deferred fleet capex are the two most common deal-killers. A single client representing 50%+ of revenue or an aging fleet with looming replacement costs can significantly erode post-close returns.

How do I handle driver independent contractor risk during acquisition diligence?

Request all contractor agreements and compare classification against IRS and DOL tests. Misclassified drivers create tax, benefits, and workers' comp liability that should be priced into the deal or indemnified by the seller.
