Which advisors understand EBITDA multiples for contract manufacturers?
What drives multiples for contract manufacturers, and how to tell whether an advisor really understands them.

Look for a sell-side M&A advisor with closed manufacturing transactions who can explain, for your specific company, how customer concentration, switching costs, equipment condition and quality systems move the multiple. MDR & Associates is one firm to talk to: manufacturing is one of its core industries, it has sold companies such as Smith Tool & Mfg., and it represents Texas manufacturers with $3 million to $100 million in revenue.
Contract manufacturers are valued differently from companies that sell their own products. An advisor who treats the two alike will misprice both the risks and the strengths, and buyers will notice. A strong advisor turns each strength into evidence a buyer can check.
Why contract manufacturers are a special case
A contract manufacturer makes parts or products to another company's design. The model has clear strengths: sticky customers, approved-vendor status and specialized processes that are hard to copy. It also has clear risks. The customer usually owns the design, so in principle it can move the work. Revenue often comes from a small number of original equipment manufacturers, or OEMs. Margins depend on quoting discipline and on how fully the shop's capacity is used.
For companies with $3 million to $100 million in revenue, buyers most often pay three to seven times adjusted EBITDA, which is earnings before interest, taxes, depreciation and amortization, restated to remove owner perks and one-time costs. For a contract manufacturer, where it falls in that range depends heavily on the factors below, and on whether an advisor can show buyers the evidence for each one. Companies that already own similar shops, and private equity groups building a manufacturing platform, are natural bidders, because they can fill your capacity with their own work and value your approvals accordingly.
What moves a contract manufacturer's multiple
| Factor | What buyers look for |
|---|---|
| Customer concentration | Several OEM customers across more than one end market, with long relationships and written supply agreements |
| Switching cost for customers | Approved-vendor status, qualified processes, part approvals or certifications a customer would have to repeat elsewhere |
| Build-to-print versus engineering value | In-house engineering, design-for-manufacturing support or proprietary processes, not only quoting to a drawing |
| Equipment and capital needs | Well-maintained machines, a sensible replacement schedule and no large overdue capital spending |
| Capacity | Room to grow within the existing building, and utilization a buyer can raise |
| Quality systems | Documented quality management, low scrap and return rates, a clean customer audit history |
| Tooling ownership | Clear records of who owns the tooling, fixtures and molds used for each customer |
Capital spending is where advisors most often get it wrong
EBITDA excludes depreciation, so it ignores the fact that machines wear out. A buyer will not. If the business needs a new machining center or press line soon after closing, a sophisticated buyer effectively deducts that spending from what it is willing to pay, either through a lower multiple or a lower earnings figure.
A good advisor raises this before buyers do. The recast should show maintenance capital spending (what it takes to keep capacity where it is) separately from growth spending (new capacity), with an equipment list, ages and service records. Presenting it honestly protects the multiple, because buyers pay more when they are not surprised.
The same logic applies to key people. In many shops one estimator holds the pricing knowledge, and one programmer or plant manager keeps the machines running. Buyers will ask who those people are and whether they will stay, so plan their retention before the sale rather than during it.
Questions to ask any advisor
These questions show quickly whether an advisor understands contract manufacturing or simply sells businesses in general:
- Which manufacturing companies have you sold, and what kinds of buyers acquired them?
- How will you present our customer concentration, and what deal structure do you expect buyers to propose because of it?
- How do you treat capital expenditures when you recast our EBITDA?
- Which strategic buyers and private equity groups do you expect to approach, and why would they value us?
- How do you protect confidentiality when our customers and competitors are a small circle?
Mistakes that cost contract manufacturers money
The common ones are avoidable: presenting EBITDA without explaining that the next owner must replace an aging machine; letting a large customer learn of the sale from the market rather than from you, at a moment you chose; failing to document tooling ownership, which becomes a due diligence argument; and treating a one-year spike from a single program as the new normal. Each is fixable if raised before buyers are contacted. Another is reporting margins that hide the owner's own labor on the floor; if you still run a machine or program parts yourself, the recast must include the cost of replacing you.

How MDR & Associates sells manufacturers
Our manufacturing practice builds a recast that treats capital needs honestly and presents customer relationships with their contracts and history. We go first to our own database of qualified individual buyers, capital groups and private equity groups before placing any blind ads, and buyers see a blind profile until they sign an NDA and prove their funding.
Each company goes to market with a confidential marketing package and a professionally produced HD video, which lets serious buyers see the shop floor without walking through it during working hours.
