Key Takeaways
- A dental practice sale earnout ties part of the purchase price to post-close performance targets, which shifts risk to the seller after control transfers to the buyer.
- EBITDA-based earnouts can be heavily influenced by buyer-controlled overhead allocations, while collections or revenue metrics are generally harder to suppress.
- Pro-rata payout structures with defined floors and cumulative catch-up can protect sellers more effectively than all-or-nothing thresholds that wipe out the earnout on a near-miss.
- Clear operating covenants, monthly reporting, audit rights, and narrow definitions of termination “cause” can be essential to prevent buyers from suppressing earnout metrics.
- McLerran & Associates offers sell-side guidance on structuring and negotiating dental practice earnouts to help practice owners improve their outcomes.

Why The Earnout Clause Often Drives Your Real Sale Proceeds
The earnout clause is often the most misunderstood and most negotiable part of a DSO or private-equity term sheet. Many owners focus on the headline number and treat the earnout as a formality. That approach can leave significant money on the table.
Industry data on private-target deals indicates that just over half of deals containing an earnout see any payout at all, and blended across every earnout dollar at stake, including deals that pay nothing, sellers collect only a fraction of the contingent amount. The gap between the headline and the realized number usually traces back to clause language the seller did not negotiate.
A practice owner sells once in a lifetime. A DSO negotiates deals every week. That information gap is real, and the earnout clause is often where it quietly causes the most damage.
What A Dental Practice Sale Earnout Is And Why DSOs Use It
An earnout bridges the gap between the seller’s asking valuation and the buyer’s willingness to pay it. In DSO and private-equity affiliations, the deal typically blends three forms of consideration: cash at close, equity (held at the joint-venture level or the holding-company level), and an earnout. A substantial portion of a DSO deal can be paid in equity rather than cash, with an earnout layered on top.
The buyer’s rationale is straightforward. Earnouts transfer integration and performance risk to the seller, and they let the buyer headline a higher total number than it would pay all cash. That higher headline is what the seller is trading for, but the trade only works when the clause is drafted so the contingent portion is realistically collectible.
The core tension is that after closing, the buyer controls the levers that produce the earnout metric. Overhead, scheduling, and payer strategy all sit with the buyer, while the seller lives inside a measurement system administered by the other side for 3 to 5 years.
Earnouts are less common in doctor-to-doctor walk-away sales, where the seller typically works back only about 4–8 weeks. They are more common in DSO affiliations, where a 5-year working agreement is typical and the earnout period usually sits inside that employment window.
Earnout Structure: Cash At Close, Contingent Consideration, And Measurement Periods
Dental practice earnouts commonly defer a meaningful portion of the purchase price. That portion is paid only if the practice hits agreed targets over a measurement period. Measurement periods typically run 12 to 36 months, and many deals use shorter 12- to 24-month windows.
The earnout is one piece of total consideration and should be evaluated alongside cash at close, equity structure, and post-close compensation. The measurement period also interacts directly with the working agreement. In DSO deals, the earnout period typically sits inside the employment period, which creates specific risks if the seller’s role changes or employment ends before the measurement period concludes.
Equity held at the joint-venture level typically provides distributions and a higher floor but a lower ceiling. Equity held at the holding-company level usually offers no distributions but a higher ceiling that can multiply several times over at a future recapitalization. The earnout is separate from both and works best when modeled alongside them across 3-, 5-, 7-, and 10-year horizons to create a realistic after-tax comparison.
What To Ask For: A written schedule showing total consideration by year, by structure, and by tax treatment.
What To Refuse: An earnout defined only as a percentage of “total consideration” without a clear dollar floor or a defined metric.

Metric Selection: EBITDA Vs. Collections Vs. Revenue In A Dental Practice Earnout
Once the measurement period is set, the next question is what the earnout actually measures, and that choice can shape how easily the buyer can influence the outcome. Metric selection is often the most consequential earnout negotiation decision.
EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortization, a measure of operating profitability) aligns with how DSOs value practices. It is also the most manipulable metric because the buyer controls corporate overhead allocation, marketing spend, staffing levels, and patient scheduling after close.
Corporate allocations on collections can add substantial expense, reducing measured EBITDA and cutting an earnout to zero, even when the practice’s collections and underlying operations remain unchanged. In that situation, the practice performed, but the clause did not protect the seller.
Additional dental-specific EBITDA manipulation tactics can include replacing visiting specialist arrangements with platform specialists (shifting compensation and supplies onto the practice’s P&L), routing high-margin procedures to sister locations, and scheduling facility renovations during the measurement year.
A collections-based earnout target is generally harder for a buyer to manipulate through accounting discretion because management fees and overhead allocations do not affect collections, although it still remains exposed to payer mix changes, fee schedule reductions, and marketing cuts. Revenue usually cannot be suppressed without damaging the acquired asset and is verifiable from billing records, while EBITDA is exposed to group overhead allocations, management fees, and integration costs at the buyer’s discretion.
What To Ask For: A defined EBITDA calculation with a fixed add-back schedule, a cap on corporate overhead allocation stated as a percentage of collections, and a requirement that marketing spend and staffing be maintained at pre-close levels. If the buyer insists on EBITDA, attach a worked sample calculation as an exhibit using real trailing-12-month numbers.
What To Refuse: An earnout based on “EBITDA as determined by the buyer” or “EBITDA calculated in accordance with the buyer’s accounting policies” without defined exclusions.
Pro-Rata, Tiered, And All-Or-Nothing Payout Structures
The payout structure determines what happens when a seller misses an earnout target by a small margin, and most earnout agreements leave that situation unresolved in the buyer’s favor.
Under an all-or-nothing threshold, if the practice hits 99% of the target, the seller receives zero. Sliding-scale or tiered payout structures can produce fewer disputes than binary cliff structures because there is no single all-or-nothing cliff to argue over. All-or-nothing structures are typically the most seller-hostile approach.
A pro-rata structure pays the seller a proportional amount based on the percentage of the target achieved. Example clause language to request: “If the Earnout EBITDA for the applicable Earnout Year is less than the Target EBITDA but greater than 80% of the Target EBITDA, the Earnout Payment shall equal the Earnout Maximum multiplied by a fraction, the numerator of which is the actual Earnout EBITDA and the denominator of which is the Target EBITDA.”
Tiered structures pay higher percentages as the practice exceeds the target, rewarding upside without creating a cliff. Sellers often benefit from pro-rata earnout payments with cumulative catch-up, so a weak year followed by strong years can still produce payment.
What To Ask For: Pro-rata payout with a defined floor and cumulative measurement so a strong year can recover a weak one.
What To Refuse: All-or-nothing thresholds and any structure where a single missed month or quarter eliminates the entire earnout.

Operating Covenants: Preventing The Buyer From Suppressing The Earnout Metric
After closing, the buyer runs the practice and its decisions determine whether the seller gets paid. Written operating covenants, which are contractual commitments governing how the buyer will run the business during the measurement period, give the seller recourse when buyer choices suppress the metric.
A DSO can reduce an EBITDA-based earnout by cutting marketing spend, reducing staffing or hygiene hours, reallocating patients to other locations, changing the fee schedule, delaying equipment purchases, or allocating corporate overhead to the practice. Each of those levers is a candidate for a specific covenant, such as commitments to maintain staffing, marketing spend, or capital investment, and restrictions on diverting revenue or key employees away from the acquired business.
Employment agreement termination clauses allowing the DSO to terminate “without cause” can forfeit earnout payments mid-payment period. These protections work best when negotiated before signing the letter of intent. The seller’s role, schedule, and clinical autonomy should be defined in the employment agreement so the buyer cannot materially change the seller’s ability to produce.
What To Ask For: Written operating covenants with specific dollar or percentage floors for marketing spend and staffing ratios, a cap on corporate overhead allocation, no reallocation of patients outside the practice without consent, and a remedy if the buyer breaches, such as earnout acceleration or payment at target.
What To Refuse: “Buyer shall operate the practice in the ordinary course” without defined floors, specific cost categories, or enforceable remedies.
Audit, Reporting, And Dispute-Resolution Rights
Operating covenants only matter if the seller can confirm the buyer is honoring them. A seller cannot negotiate an earnout they cannot verify, so information rights become central.
Sellers can request monthly practice-level P&Ls delivered on a defined schedule, the right to audit the earnout calculation, and a named independent accountant to resolve disputes, because by year two the buyer representative who negotiated the deal may have changed jobs.
Monthly reporting should include the practice P&L, the EBITDA calculation with add-backs itemized, collections and production reports, and patient retention metrics. A provision requiring the buyer to maintain separate books and records for the acquired business during the earnout period can be a valuable safeguard for sellers.
The audit right should specify that the seller may audit the buyer’s calculation of the earnout metric, with the cost of the audit borne by the buyer if the audit reveals an underpayment above a defined threshold. A well-drafted earnout dispute-resolution waterfall runs on a defined timeline. The buyer delivers the calculation within 60 to 90 days of the measurement period ending. The seller then has 30 to 60 days to object with specifics. The parties negotiate in good faith for a set window. Unresolved disputes go to a jointly selected independent accountant whose decision is binding.
What To Ask For: Monthly reporting within 30 days of each period, an annual audit right, and a 30–60 day dispute-resolution timeline with an independent accountant using baseball arbitration, where the accountant chooses between the buyer’s number and the seller’s.
What To Refuse: Annual reporting only, no audit right, and dispute resolution that requires litigation as the first step.

Employment-Termination And Practice-Resale Triggers
Employment and resale triggers often create gaps in standard DSO earnout documents. The agreement needs to address what happens to the earnout if the buyer terminates the seller’s employment, if the seller resigns, or if the buyer sells the practice before the earnout period ends.
Termination Without Cause
The earnout can be structured to accelerate or be paid at target when termination occurs without cause. Cause should be limited to serious misconduct such as fraud, breach, or gross misconduct. Termination without cause can trigger either pro-rata payment or a presumption that the applicable targets were satisfied.
Termination For Cause
“Cause” should be defined narrowly and specifically. A broad definition gives the buyer a mechanism to eliminate the earnout. For-cause termination protection usually defines “cause” to include fraud, felony conviction, gross negligence, willful misconduct, or material uncured breach of the employment agreement, and excludes generic “underperformance” or “strategic fit.”
Resignation For Good Reason
“Good reason” can be defined to include material changes to the seller’s role, schedule, compensation, or clinical autonomy. That definition supports the seller if the buyer materially changes the working arrangement.
Practice Resale
A well-drafted earnout may accelerate upon sale or transfer of all or substantially all of the business, a buyer change of control without written successor assumption, material breach of operating covenants, or termination without cause of a protected key employee. With a majority of earnout deals (75% per the ABA 2023 study) excluding acceleration if the buyer sells the acquired business, a private-equity buyer can acquire the practice, hold for a period, sell to another buyer at a higher multiple, and the seller’s earnout can disappear because the new owner has no contractual obligation under the original agreement.
What To Ask For: Acceleration on termination without cause or resignation for good reason, a narrow definition of cause with a notice-and-cure period, and survival or acceleration on resale with written successor assumption.
What To Refuse: A broad definition of cause and any structure where the earnout is forfeited if the seller’s employment ends for any reason.
How Dental Practice Earnout Payments Are Taxed
The tax treatment of earnout payments is a key question in a dental-specific context and can be worth hundreds of thousands of dollars.
The core distinction is that earnout payments structured as purchase-price proceeds are generally treated as capital gain, while earnout payments structured as compensation for services are treated as ordinary income and may be subject to payroll taxes. The difference between the long-term capital gains rate and the top ordinary income bracket can be substantial on a multi-million-dollar earnout.
Buyers and sellers often have opposing tax incentives. A seller usually prefers the earnout treated as part of the purchase price, which points toward capital-gain treatment. A buyer may prefer a structure that preserves broader deductions or shifts more of the economics into compensation-like treatment, which points toward ordinary income that is deductible to the buyer.
The IRS looks at economic substance, not just contract labels. An earnout conditioned on continued employment, forfeited on departure, and sized by job function or prior wages points toward compensation taxed as ordinary income. An earnout tied to the business’s own performance, paid pro rata according to ownership interests, and continuing even if the seller leaves or dies supports purchase-price and capital-gain treatment.
If the earnout is tied to continued employment, the IRS may treat it as compensation regardless of how the contract labels it. If an earnout payment is characterized as compensation, it may in some circumstances trigger deferred compensation rules under Internal Revenue Code Section 409A, which can lead to severe adverse consequences for the seller.
Also, a portion of each earnout payment may be recharacterized as ordinary interest income under imputed interest rules, regardless of what the contract states about interest. This is a common audit trigger that a dental-specific M&A tax advisor can address in the agreement’s drafting.
What To Ask For: Explicit language that earnout payments are purchase-price proceeds, a separate market-rate employment agreement for any post-close services, and a tax advisor who specializes in dental M&A before signing.
What To Refuse: Earnout language that ties payment to continued employment without addressing tax treatment, and any structure where the earnout formula tracks the seller’s personal performance rather than the business’s standalone results.

Earnout Vs. All-Cash Dental Practice Sale: When To Accept Contingent Consideration
An earnout can make sense when the buyer is well-backed and well-run, the metric is collections-based or supported by strong operating covenants, the pro-rata structure protects against near-misses, and the total consideration, including cash, earnout, and equity, is materially higher than an all-cash offer. An earnout can also be workable when it bridges a genuine growth-story gap on seller-protective terms, the period is 12 to 24 months, the metric is revenue, and an operating covenant caps integration interference during the measurement window.
Walking away can be prudent when the earnout is all-or-nothing, when the metric is buyer-determined EBITDA with no operating covenants, when the buyer has a history of post-close disputes, or when the earnout represents a large share of total consideration and the seller cannot verify the metric. Advisors in healthcare practice sales suggest keeping an earnout to 20% or less of deal value, and accepting more only when there is no equity rollover.
The highest headline number does not always translate into the strongest outcome. The more useful comparison is after-tax cash across time horizons, which is what a multi-year, multi-structure financial forecast can provide. A revenue-based earnout over 18 months with a standalone covenant can be worth more than an EBITDA earnout over 3 years, even when the headline number appears smaller.
What To Ask For: A side-by-side comparison of all-cash, cash-plus-earnout, and cash-plus-equity structures over 3-, 5-, 7-, and 10-year horizons, with after-tax proceeds modeled for each.
What To Refuse: Any deal where the earnout is more than a modest share of total consideration and the seller has no audit rights or operating covenants.

Why McLerran & Associates Is A Helpful Sell-Side Advisor For Earnout Negotiations
McLerran & Associates is a dental-specific sell-side M&A advisory and brokerage firm. It is one of the few that runs both private-buyer and DSO transitions in roughly equal measure. The firm has evaluated thousands of dental practices and completed many successful practice sales. Its team of former investment bankers, practice-finance lenders, DSO buyers, CPAs, and advisors brings over 100 years of collective dental-industry experience.
On earnout negotiations specifically, McLerran’s approach starts with a CPA-led, diligence-grade EBITDA analysis completed before the deal goes to market. That preparation helps the number that anchors the earnout hold up under buyer scrutiny and reduces the risk of a re-trade in diligence. From that foundation, the firm runs a structured, auction-like bid process, typically 45–60 days and generating multiple offers, which can create competitive tension so buyers move contingent dollars toward cash at close.
McLerran evaluates DSO and private-equity buyers like investments and has blacklisted buyers known for poor post-close environments. That screening can reduce the risk of an earnout being suppressed by a poorly run buyer. The firm’s multi-year, multi-structure financial forecasting models cash, equity, and earnout outcomes across 3-, 5-, 7-, and 10-year horizons, including conservative recapitalization assumptions, so the seller can compare after-tax proceeds across deal structures rather than relying on headline numbers.
McLerran’s transaction experience compares favorably to broader industry norms, and clients often achieve higher valuations than owners who sell on their own. The firm is sell-side only and does not represent buyers, so its incentives remain aligned with the seller in every earnout negotiation.
McLerran operates nationally, with regional offices led by Justin Klingshim in Cleveland, Matt Sutton in Atlanta, Andrew Kobylski in Northern Virginia, Steven Au in Los Angeles, and Brian Carroll in Phoenix covering the Mountain West. Owners who have not yet decided whether to sell can attend the McLerran M&A Summit (October 29–30, 2026) to learn about deal structures, EBITDA, and the DSO landscape before committing, and to receive a complimentary practice valuation.

FAQ: Dental Practice Sale Earnout Questions
What Is A Dental Practice Sale Earnout?
A dental practice sale earnout is a contractual provision that makes a portion of the purchase price contingent on the practice hitting specific performance targets after closing. In a typical DSO or private-equity deal, a significant portion of consideration is paid at close and a smaller portion is contingent on post-close performance over a defined measurement period. The seller loses operational control at closing but still depends on the buyer’s decisions to receive the contingent portion, which is why the clause language, rather than the headline number, often determines what the owner actually walks away with.
What Percentage Of A Dental Practice Sale Is Typically Paid As An Earnout?
The earnout portion is commonly a meaningful share of total consideration, with the remainder paid as cash at close and, in many DSO deals, equity. The percentage can vary with the buyer type, the practice’s financial profile, and the seller’s willingness to accept contingent consideration. Platform private-equity acquisitions may structure a smaller earnout percentage alongside a larger equity rollover, while add-on DSO acquisitions commonly use earnouts to bridge seller-buyer valuation gaps, typically at 10–25% of purchase price over 12–36 months. Add-on earnouts tend to be shorter, with 2-year production-milestone structures common, and are often tied to retention or protection metrics. Longer 3-plus-year earnouts appear more often in platform deals. The earnout should be evaluated alongside cash at close, equity structure, and post-close compensation to understand the full economic picture.
What Happens If You Miss A Dental Practice Earnout Target?
The outcome depends on the payout structure in the agreement. Under an all-or-nothing structure, a near-miss, even 99% of target, can mean zero payout. Under a pro-rata structure, the seller receives a proportional payout based on the percentage of the target achieved. Under a tiered structure, the seller may receive partial payment above a floor and full payment at or above target. Under a pro-rata structure with a floor, a near-miss still pays a proportional amount, and cumulative measurement can allow a strong year to offset a weaker one. See the payout-structure section above for specific examples.
EBITDA Vs. Collections: Which Is Better For A Dental Practice Earnout?
Collections-based earnouts are generally harder for a buyer to manipulate through accounting discretion because management fees and overhead allocations do not affect collections. EBITDA-based earnouts align with how DSOs value practices but can be influenced by buyer-controlled overhead allocation, marketing spend, staffing, and patient scheduling after close. A buyer can suppress measured EBITDA without changing clinical production or collections by allocating corporate overhead to the practice, replacing visiting specialist arrangements with platform specialists, or routing high-margin procedures to sister locations. If the buyer insists on EBITDA, the seller can request a fixed add-back schedule, a cap on corporate overhead allocation, and operating covenants maintaining pre-close staffing and marketing levels.
How Are Dental Practice Earnout Payments Taxed?
Earnout payments are generally taxed as capital gain when structured as purchase-price proceeds and as ordinary income when structured as compensation for services. The IRS focuses on economic substance rather than contract labels, so an earnout tied to continued employment may be taxed as compensation even if the agreement describes it as purchase price. See the tax section above for the main factors that can influence this distinction.
