How Should a DSO Evaluate Provider Dependency?

DentalDex · Acquisition underwriting · 3 min read · Methodology

Provider dependency measures how much practice revenue depends on one dentist, usually the selling owner, and therefore how much revenue could be at risk if that provider reduces production or leaves. It is the factor most likely to turn a good acquisition into a bad one, and the one most often under-weighted at IOI because the teaser shows total collections, not who produced them.

The metric

Owner dependency = owner's doctor production ÷ total doctor production, excluding hygiene.

Total doctor production of $2M with owner production of $1.5M gives owner dependency of 75%. The same practice with the owner at $600K is 30%. Same EBITDA, very different risk.

Reading the number

Owner dependency	What it usually means	Structural response
Under 40%	Practice runs on a provider team; owner is one of several	Standard structure; premium multiple justified
40–60%	Owner is the lead producer but not the practice	Standard structure with a 2-year transition; confirm associate retention
60–75%	Practice is the owner plus support	Longer employment term, retention bonus, part of price in earn-out tied to production
Over 75%	You are buying the owner's schedule	Price on post-owner EBITDA, 3+ year term, or pass unless you can recruit into the market

Dependency is not automatically a deal killer

A high-dependency practice can still be attractive when the seller remains several years, strong associates exist, the recruiting market is favorable, demand exceeds current capacity, or the DSO has proven recruiting infrastructure. The key is pricing the risk and solving the transition, not pretending the number is lower than it is.

Evaluate more than the percentage

The same 75% can hide two very different practices.

• What the owner produces. A GP doing crowns, fillings and hygiene exams is replaceable with a general associate in most markets. A GP whose 75% is implants, full-arch and sedation cases is not; that production leaves with the skill set.
• How the owner produces it. 75% on three clinical days means the practice is under-scheduled and an associate can absorb volume. 75% on five long days means the owner is the capacity.
• Who the patients think they see. Ask the front desk how often patients request the owner by name. Ask what happened to the schedule the last time the owner took two weeks off.
• How the associate got there. An associate producing 25% after eight months is ramping. One producing 25% after four years is capped, either by the schedule or by the owner keeping the good cases.
• Local recruiting. In a metro with a dental school, a 70% owner is a 12-month problem. In a rural county, it is a 3-year one.

Worked example

Practice: $2.4M collections, $580K EBITDA, owner produces $1.45M of $1.85M doctor production (78%). One associate at $400K, three years' tenure. Owner is 61, willing to stay 3 years. Hygiene strong at 30%.

Base case at 5.5x: $3.19M. The dependency-adjusted view:

• Year 1–3 with owner producing: EBITDA holds.
• Year 4, owner gone, replaced by an associate at 30% of production: replacement cost is roughly $435K against $1.45M of production, but a new associate typically ramps to 70–80% of the departing owner's production in year one. Modeled year-4 EBITDA falls to roughly $350K–$420K before recruiting cost.

A buyer who prices this at 5.5x on $580K is paying for three years of the owner's production and hoping. A buyer who prices it at 5.0x with $400K in a year-3 earn-out tied to associate production growth has aligned the seller with the transition and protected the year-4 number.

Link structure to risk

Provider risk should show up in the structure, not just the multiple:

• Employment term long enough to recruit and ramp a replacement, plus a year.
• Earn-out tied to the metric you are worried about, usually associate or total production rather than EBITDA, which the seller no longer controls.
• Retention incentives for the existing associate, agreed before closing.
• Replacement plan with a named recruiter and a budget, in the integration plan before LOI.

What to record

At IOI, LOI and close, record owner dependency, associate count and tenure, and the employment term agreed. Twelve months after close, record actual production by provider. That comparison across your portfolio is the only reliable way to learn how much a point of dependency is really worth in your markets.
