Due diligence
What to Look For
Practical guidance from hundreds of real acquisition conversations.
Customer Mix and Concentration
- Ask for a revenue breakdown by end market and by customer.
- Shops serving automotive, aerospace, defense, and industrial customers are far more resilient than those dependent on a single industry.
- If one customer makes up more than 20 percent of revenue, dig into the relationship history, contract terms, and how many contacts you have at that account.
- Diversification across industries and across contacts within those industries is what gives you real confidence that the business holds up through a slow period in any one sector.
Equipment Condition and Maintenance History
- Ask for a full equipment list with age, hours, maintenance logs, and any recent repairs or rebuilds.
- Condition matters more than age — a well-maintained CNC with documented service history is more valuable than a newer machine with no records.
- Ask which machines are still supported with parts and whether any critical equipment is approaching end of life.
Certifications and Approved Vendor Status
- Ask which certifications the business holds, when each was last audited, and which customers specifically require those credentials.
- ISO 9001 or AS9100 certifications and positions on aerospace or defense approved vendor lists take years to earn and create genuine lock-in with customers who require them.
- Certifications that are current and well-maintained are meaningful value drivers and not easy to replicate.
Shop Leadership Independence
- Ask who runs the shop on a day when the owner is not there.
- A shop floor supervisor who handles quoting, scheduling, and quality sign-off without the owner is what separates an operational business from an owner-dependent one.
- The answer tells you a lot about what a transition would actually look like and how much operational continuity you can count on from day one.
