Machine Shop for Sale: What Buyers Get Wrong

Most people who look at a machine shop for sale are thinking about the equipment.

They see a Haas vertical machining center, a CNC lathe, a full floor of tooling, and they assume the value is in the iron. It is not. The value is in the contracts, the operator base, and whether the shop can survive the owner walking out the door.

Get that wrong and you have bought yourself an expensive collection of depreciating machines. Here is what a serious buyer actually needs to know before making an offer on a machine shop.

Why Machine Shops Are Worth a Hard Look

Manufacturing businesses, and machine shops specifically, are some of the better acquisition targets in the $500K to $5M range. The reasons are straightforward.

They have real assets. Equipment appraises at tangible value, which makes SBA lenders more comfortable with the deal. In most business acquisitions, you are buying goodwill and cash flow. A machine shop gives you hard collateral on top of that.

They also have recurring revenue from established customers. A shop that has been supplying aerospace components or medical device parts to the same three customers for eight years has genuine switching costs on the buyer’s side. Re-qualifying a new supplier is expensive and carries quality risk. Nobody changes suppliers unless they have to.

And skilled machinists are hard to find. A shop with a stable team of experienced operators is worth more than its revenue suggests, because replacing those people in the current labor environment is genuinely difficult.

The catch is that these same strengths create specific risks. We will get to those.

Run the Debt Service Math First

Before you fall in love with a shop, run a quick back-of-envelope debt service check.

A standard SBA 7(a) acquisition loan runs 10 years. At current rates, rough monthly debt service on a $1M loan is somewhere around $11,000 to $12,000 per month, or $132,000 to $144,000 annually. Scale that to whatever acquisition price you are looking at.

Our minimum target is 2x debt service coverage ratio (DSCR). The floor is 1.5x, and anything at 1.25x is dangerous territory regardless of what the broker tells you.

Here is the part most buyers miss: SDE, as presented on a broker listing, is almost always inflated. The add-backs are generous, the adjustments are seller-friendly, and the number is designed to make the deal look good. We discount SDE by 15% to 50% depending on the quality of the financials, then use that discounted figure as the real cash flow input for DSCR analysis. If the discounted number does not clear 2x, the deal does not work at the listed price.

Say you are looking at a machine shop listed at $1.8M. Annual debt service on $1.62M (the SBA portion after 10% equity injection) would be roughly $190,000 to $210,000. The broker says SDE is $350,000. After a 20% discount for questionable add-backs, you are working with $280,000. That puts your DSCR at about 1.4x. Not enough. You either negotiate the price down or you walk.

Most buyers skip this step and fall into diligence before confirming the math. Do not do that.

The Equipment Valuation Problem

This is where machine shop acquisitions get complicated relative to service businesses.

Equipment appraisals matter, but not in the way most buyers assume. The question is not what the machines are worth at auction. The question is whether the equipment is appropriate for the type of work the shop currently does, and whether it is maintained well enough to keep doing it.

A 15-year-old Mazak with deferred maintenance and worn tooling holders is not an asset. It is a liability disguised as a line item on a balance sheet.

When we evaluate a machine shop for a client, we look at three things on the equipment side.

Age and maintenance records. CNC machines that have been properly maintained and have documented service histories are worth closer to their appraised value. Machines that have been run hard with no records get discounted heavily in our models.

Capacity utilization. If the shop is running two shifts and the machines are at 85% capacity, growth is constrained without adding equipment. If they are at 40% capacity, there is room to grow revenue without capital expenditure. Big difference.

Technology fit. A shop with older manual mills and lathes competing for work against newer shops running 5-axis CNC is in a structurally weaker position. That needs to be priced in.

Your equipment appraisal should be done by a certified machinery and equipment appraiser (CMEA) who actually knows manufacturing. Not a generalist who values dental practices and machine shops with the same spreadsheet. The difference matters.

Owner Concentration: The Risk That Kills These Deals

Worth putting this up front because it shows up more often than any other single issue.

A machine shop where the owner is the primary customer relationship manager, the primary estimator, and the person who personally oversees quality control is not a sellable business. It is a job that happens to have employees.

When you are evaluating a machine shop for sale, ask these questions directly:

Who handles customer quotes and estimating? If the answer is the owner, that is a red flag. Estimating is a specialized skill, and losing the person who does it means you lose the ability to price new work.
Who are the top three customers, and what percentage of revenue do they represent? Anything over 40% from a single customer is a concentration risk. SBA lenders will flag this, and they are right to.
Do customers have contracts or is the relationship informal? Informal relationships that exist because the owner golfs with the purchasing manager at a key account are worth nothing after the sale.
How long has the management team been in place? A shop with a general manager and production supervisor who have been there 5 or more years is dramatically more transferable than one where the owner runs everything directly.

Owner concentration is not an automatic deal-killer. But it changes the price and it changes the transition structure. A seller who runs everything and is willing to stay on for 12 months is a different proposition from one who stays 30 days.

Price that difference in accordingly.

How SBA 7(a) Financing Works on a Machine Shop Deal

The SBA 7(a) loan is the right tool for most machine shop acquisitions in the $500K to $5M range.

You bring 10% equity injection. The SBA loan covers the rest, up to $5M. On a $2M acquisition, that means $200K out of pocket and $1.8M financed. The loan term for business acquisitions is 10 years. Real estate, if the property is included, can extend to 25 years.

That real estate piece matters for machine shops because many of them own their building. If real estate is part of the deal, you may be able to split the financing (one note for the business, one for the property), which changes the debt service math significantly.

Seller notes are common in manufacturing deals. In our experience, the right structure is a 10-year full standby note at 0% interest. We achieve that structure on more than 90% of our deals. A standby seller note does not count against debt service during the SBA loan term, which means it does not hurt your DSCR calculation during underwriting. That is a material advantage.

The SBA does require the seller note to be on full standby if it is being excluded from the DSCR calculation, so this has to be structured correctly from the start. Your lender needs to know this is the plan before you get to the term sheet stage.

Side note: do not forget working capital. You need 2 to 6 months of operating expenses set aside, separate from the acquisition price. Machine shops have real carrying costs (raw materials, tooling, payroll for machinists) and you cannot run thin on cash in the first 90 days. Some buyers build this into the SBA loan. Others fund it separately. Either way, it is non-negotiable. Plan for it in your total out-of-pocket number from day one.

So that covers the structure. Now here is what a good deal actually looks like in practice.

Say you are looking at a precision CNC shop doing $3.2M in revenue with $520K in broker-listed SDE. The owner has been there 22 years and wants out. The shop has three long-term employees, including a shop foreman who has run daily operations for nine years.

Listed at $1.95M. Roughly 3.75x SDE. Fair, not cheap.

But remember, SDE needs to be discounted. After reviewing tax returns and running proof of cash (where bank deposits are matched against reported revenue, line by line), the real adjusted cash flow comes in around $440K. Still solid. Debt service on $1.755M at 10-year SBA terms is roughly $205,000 annually. DSCR on the discounted number comes in at about 2.15x. That clears our 2x target.

Owner concentration check: the foreman handles scheduling and quality. An office manager handles invoicing and vendor relations. The owner’s primary role is customer development with two anchor accounts. You negotiate 12 months of seller transition, structured as post-close consulting. The top customer is contacted during diligence and confirms they plan to continue.

Equipment: 7 CNC machines ranging from 3 to 11 years old. All have service records. Utilization at 65%. Room to grow without new capex.

That is a deal worth pursuing. It will not be easy to close, but the structure makes sense.

Frequently Asked Questions

Is a machine shop a good business to buy with an SBA loan?

Machine shops are generally strong candidates for SBA 7(a) financing. They have tangible equipment that serves as collateral, established cash flows, and recurring customer relationships. The main hurdles are verifying real cash flow (not just the broker’s SDE figure), managing owner concentration risk, and ensuring equipment is appraised by a qualified CMEA. When the discounted numbers clear a 2x DSCR, lenders are typically receptive.

How much do I need to put down to buy a machine shop?

SBA 7(a) loans require a minimum 10% equity injection on business acquisitions. On a $1.5M machine shop, that is $150,000 out of pocket. That equity can come from personal savings, a 401(k) rollover via a ROBS structure, or a home equity line, among other sources. The SBA finances the remaining 90%, up to a $5M maximum loan amount. Budget separately for working capital.

What is a fair multiple for a machine shop acquisition?

Most machine shops in the $500K to $5M acquisition range sell for 2.5x to 4x SDE, depending on customer concentration, equipment condition, revenue stability, and transferability of key relationships. Shops with high customer concentration, aging equipment, or heavy owner dependence should be priced toward the lower end. Shops with contracts, modern equipment, and stable management command higher multiples.

How do I evaluate the equipment in a machine shop I want to buy?

Hire a certified machinery and equipment appraiser (CMEA) with manufacturing experience. They will assess fair market value, replacement cost, and whether the equipment is appropriate for the work the shop currently does. Look at maintenance records, capacity utilization, and how modern the technology is relative to the shop’s competitive position. Equipment run without documentation or maintenance should be discounted in your offer price.

What happens to customer contracts when a machine shop is sold?

Most machine shop customer relationships are informal. There is typically no legal obligation for a customer to continue buying after a change of ownership. During due diligence, contact key customers directly (with the seller’s permission) to confirm their intent to continue. Long-term purchase agreements or master supply agreements, if they exist, should be reviewed by your attorney to confirm they are assignable to the new owner.

Ready to Evaluate a Machine Shop Acquisition?

Buying a machine shop is one of the better paths to acquiring a real, asset-backed business with defensible cash flow. It is also more technically complex to evaluate than a service business, which means the buyers who do their homework have a significant advantage over those who rely on the broker’s deck.

Regalis Capital works with buyers pursuing manufacturing acquisitions, including machine shops. We review more than 120 deals per week, run the financial analysis, negotiate deal terms, and manage the SBA process from first contact to close.
