What Private Equity Buyers Look at in a Machine Shop Beyond EBITDA
Kalk Solutions Editorial
TL;DR
EBITDA sets the starting point, but the multiple depends on risk. When buying a machine shop, private equity checks customer concentration, owner dependence, how new business is generated, quality of systems and data, workforce depth, equipment age and certifications. Shops that can show a documented pipeline, diversified customers and a team that runs without the owner usually attract more buyers and better terms.
Quick answers
- What do private equity buyers look for in a machine shop?
- Beyond EBITDA: customer diversification, revenue that does not depend on the owner, a repeatable way to win new customers, clean financial and operating data, a capable management team, certifications, and the condition of equipment.
- How is a machine shop valued?
- Usually as a multiple of adjusted EBITDA. The multiple rises or falls based on risk factors like concentration, owner dependence, growth potential and systems.
- What lowers the value of a machine shop?
- One customer above 25 to 30% of revenue, an owner who holds all key relationships, no documented sales process, aging equipment, and messy data.
If you are thinking about selling a machine shop, you have probably heard "it all comes down to EBITDA." EBITDA is the starting point. The multiple applied to it is decided by risk, and that is where most owners leave money on the table.
This is general information, not financial or legal advice. Talk to an M&A advisor and accountant for your situation.
How buyers think about value
Atomic answer: value is roughly adjusted EBITDA times a multiple. The multiple reflects how confident the buyer is that earnings will continue and grow after you leave.
Two shops with the same EBITDA can receive very different offers. The difference is in the items below.
The 8 things PE buyers check beyond EBITDA
1. Customer concentration
One customer above 25 to 30% is a red flag. See customer concentration risk.
2. Owner dependence
Do customers buy from the company or from you? See your shop runs on the owner's phone contacts.
3. How new business is won
Buyers want a repeatable engine, not luck. A documented pipeline and inbound RFQs are strong evidence. Read how a documented sales pipeline increases what your business sells for.
4. Systems and data
Can you produce job costing, on-time delivery, quote win rate and margin by customer? Shops running on spreadsheets and memory struggle in due diligence. See ERP for small manufacturers.
5. Management depth
Is there a production manager, quality manager and estimator who can run the shop?
6. Workforce
Skilled machinist retention, training programs, age profile and wage competitiveness.
7. Equipment and capacity
Age, maintenance records, utilization and room to grow.
8. Certifications and industries
AS9100, ISO 13485, ITAR registration and IATF open doors to sticky, higher-margin work, and are attractive to platform buyers.

Questions about this topic
How early should I prepare to sell?
Ideally three to five years. Many value drivers, like customer diversification and a second-level management team, take time to build.
Do PE firms care about my website?
Indirectly. They care whether the business can win new customers without the owner. A website that generates RFQs is evidence of that.
What is an add-on acquisition?
When a PE-backed platform company buys smaller shops to add capabilities or regions. Many $5M to $30M machine shops are bought this way.
