Editorial update, October 3, 2026: The manufacturing example below is hypothetical. Its multiples are illustrative assumptions. The comparison and image caption have been clarified; no completed sale is being reported. The customer-concentration guideline has also been clarified to reflect my M&A experience and variation among buyers.
There's a concept in business valuation that most owners only encounter once during their own sale process, when it's too late to do much about it.
It's called owner dependency risk: the risk that earnings or operations weaken when the owner leaves. The hypothetical example below shows how a lower assumed multiple changes the valuation arithmetic.
It has nothing to do with revenue growth. Nothing to do with profitability. It's about what happens to the business when the owner is no longer in it.
How Buyers Actually Think About Risk
When a buyer's team enters a diligence process, they're building a mental model of the business without its current owner. Every discovery they make either strengthens or weakens that model.
They're asking specific questions:
- Which customer relationships are personal to the owner versus institutional to the business?
- Who makes operational decisions when the owner is unavailable?
- Are key processes documented, or do they exist in people's heads?
- Are supplier terms formalized, or do they depend on a personal relationship?
- Would revenue hold if the owner transitioned out over 90 days?
None of these questions appear on a P&L. But every answer influences the multiple.
The Valuation Math
Here is a hypothetical illustration, not a completed transaction.
Assume a manufacturing business has $1.2 million in adjusted EBITDA. For this example, use an assumed multiple range of 4.5–5.5x, implying a value of $5.4 million to $6.6 million. These multiples are illustrative assumptions, not a sourced market range or an appraisal.
Suppose a buyer reviewing this hypothetical business identifies three concerns:
1. Two customers representing 35% of revenue have buying relationships tied directly to the owner
2. The operations manager defers most decisions to the owner rather than acting independently
3. Key supplier agreements are informal no documented terms, no backup contacts
In this scenario, the business remains profitable, but those concerns could make a buyer less confident that its earnings will continue after the owner leaves.
Now assume the buyer applies a 3.5x multiple. The implied value would be $4.2 million, which is $1.2 million to $2.4 million below the assumed 4.5–5.5x range. Compared with exactly 5x ($6 million), the difference is $1.8 million. This illustrates sensitivity to the multiple; it does not measure a typical owner-dependence discount.
The Three Dimensions That Matter Most
Buyers evaluate stability across several dimensions. The three that most commonly compress multiples in the lower middle market:
1. Customer concentration and relationship ownership
In my M&A experience, buyers often begin to look more closely when a single customer accounts for roughly 15–20% of revenue. There is no fixed cutoff; the level of concern varies by buyer. Contract terms, the durability of the relationship, and whether it depends on the departing owner also matter. A relationship held by the business can reduce owner-dependence risk, but it does not eliminate the risk of losing the customer.

The distinction is measurable. It shows up in who the customer calls, who attends their reviews, and whether the relationship survives the owner's absence.
2. Management independence
A management team that decides is different from a management team that executes. The question isn't whether your people are capable; it's whether they have the authority, the information, and the track record of making decisions without the owner in the room.
Buyers test this during reference calls and interviews. A pattern of deferred decisions is one of the clearest signals of owner dependency.
3. Process documentation
Documented processes don't add value by themselves. What they do is reduce the risk that value walks out the door when the owner does. The businesses that command premium multiples have operating procedures, not just experienced employees.
The test is simple: could a capable person join your business and run a critical process without asking the departing owner how it works?
Why This Matters Before You're Ready to Sell
The owner dependency discount isn't only a sale problem. It's a leverage problem, a financing problem, and a personal freedom problem.
Businesses with high owner dependency are harder to finance because lenders see the same risk buyers do. They're harder to step back from because the owner becomes the single point of failure for revenue. And they're harder to grow because the owner's time becomes the constraint.
The owners who command the best outcomes whether they're selling, recapitalizing, or simply reducing their workload are the ones who addressed structural stability before the market forced their hand.
That work takes 18–36 months to show up credibly in a business. It's not a pre-sale checklist. It's an operating decision.
A Framework for Self-Assessment
Before engaging any outside process, it helps to answer these honestly:-
- What percentage of your revenue depends on relationships the owner personally holds?-
- In the last 90 days, how many significant decisions were made without the owner's direct input?
- If you listed your critical operating processes, what percentage have documented procedures?-
- What is your largest single customer as a percentage of revenue, and is that relationship owner-held or business-held?
These four questions won't give you a valuation. But they'll tell you where your structural work needs to start.
The Bottom Line
Owner dependency is one of the most common and most correctable sources of value loss in lower middle market businesses. It doesn't announce itself. It accumulates quietly over years of an owner solving things faster than anyone else could.
The good news: it's fixable. The qualifier: it takes time, and it takes starting before you need to.
