DermatologistsStart with the economic purpose and the complete price
Ask what disagreement the earnout is intended to resolve. A buyer may believe recent earnings include temporary strength, while an owner may expect new capacity, staffing, or service lines to raise future earnings. An earnout can connect some payment to that uncertain performance. If the proposal instead uses a contingent payment to defer an amount both sides already agree is owed, it may function as seller financing under another name. The distinction matters because performance risk, collection risk, and ordinary deferred payment risk need different protections.
Write the purchase price in components: cash payable at closing, any escrow or holdback, assumed liabilities, seller financing, and each earnout tranche. Record the conditions, dates or periods, and maximum amount for every component. A stated maximum is not equivalent to expected value. If the buyer says the seller can receive an additional $1 million, ask what outcomes make that amount likely and what makes it impossible. Treat rollover equity, consulting compensation, transition payments, and noncompete consideration separately, since they may carry different tax, service, or performance conditions.
Compare offers using consistent assumptions. A proposal with a higher contingent ceiling may be less valuable than a lower offer paid in cash if its threshold is demanding, its measurement is buyer-controlled, or its payment is delayed and unsecured. Include the practical cost of remaining involved, financing a transition, or waiting through disputes. The seller should understand which value depends on future operations and which value is fixed and collectible at closing. That framing keeps negotiations focused on economics instead of allowing a large maximum number to dominate the discussion.
Define the metric and payout threshold
The metric should be a formula that a finance professional can reproduce from identified records. If the earnout uses earnings, define the accounting basis and specify treatment of owner compensation, rent, management fees, shared services, acquisitions, one-time expenses, and accounting policy changes. If it uses collections or revenue, define recognition, refunds, credits, bad debt, bundled services, and timing of deposits. A phrase such as "adjusted EBITDA" is incomplete unless the agreement lists permitted adjustments and identifies who determines them.
Set a measurement period with clear start and end points, a responsible recordkeeper, and rules for partial periods. Decide how to handle a closing during a month, a billing lag after period-end, seasonal fluctuations, and a transaction that closes shortly before an unusually strong or weak quarter. If the metric is measured across several years, specify whether each period stands alone or whether losses and excess performance carry forward. A single cumulative test can reward sustained performance differently from annual tests, and both differ from a test that pays only on the final period.
A threshold defines when payment begins. State whether payment is zero below a floor, increases in steps, or rises in a straight line between the floor and cap. Include a worked formula in the contract, with examples that test the floor, the exact threshold, values between the threshold and cap, and the maximum. Avoid relying on a verbal description such as "seller receives 30 percent of growth." It leaves open the baseline, whether the percentage applies to dollars or margin, whether there is a cap, and whether the buyer can offset another period's shortfall.
Specify rounding and currency treatment, and say whether the calculation uses accrual or cash accounting. Define the baseline period using the same policies that will apply during the earnout. If an unusual event requires an adjustment, identify it by category and describe the evidence needed. An adjustment should not be permitted merely because a result looks unusual after the fact. Detailed definitions reduce arguments at the exact point when the parties may have different incentives.
Map the operating decisions that can change the result
The buyer may take control of scheduling, staffing, pricing, marketing, purchasing, payer or vendor relationships, service mix, and accounting after closing. Each decision can move the earnout metric even when the practice's underlying demand is unchanged. For example, a buyer can shift a shared expense into the acquired practice, direct opportunities to another location, or change the allocation of central support costs. Before accepting the metric, list decisions likely to affect it and identify which party will control each one.
Some decisions are ordinary integration choices. Others can directly impair the measured business. The agreement can require consistent accounting methods, commercially reasonable allocation of shared expenses, and a stated policy for charging central costs. It can require that revenue attributable to the acquired operations remain included even if the buyer moves it to another entity or location. If the buyer combines the practice with another business, specify how the original operations will be tracked and what records will permit a calculation. Avoid broad promises that the buyer must operate the business solely to maximize the earnout, since they may be impractical and difficult to enforce.
Consider whether the seller will remain employed or provide transition services. If continued services are required to earn payment, define those obligations separately from performance conditions, including how payment is treated if the buyer ends the arrangement, changes the seller's duties, or the seller cannot continue for a specified reason. A seller should not assume a business-performance earnout will be paid if the agreement actually makes it conditional on continued employment. Similarly, buyer discretion to close a location, change branding, or discontinue a service can make a revenue-based target unreachable unless the contract addresses those possibilities.
Ask for a written operating covenant that protects measurement integrity without freezing normal business decisions. Possible provisions include no diversion of included revenue, consistent expense allocation, maintenance of books sufficient to calculate the metric, notice before a material reorganization, and an agreed method for allocating results after a transfer. These protections should state remedies for breach, such as restoring the calculation, extending the period, or paying a defined amount. A promise without a measurable remedy may be hard to use when a disputed decision has already changed the result.
Request three payout illustrations
Require the buyer to show three scenarios, each using the exact proposed definition: a low case, a target case and a high case. Each example should show the baseline, operating assumptions, calculated metric, threshold, payout formula, cap plus payment date. Ask for a bridge from the practice's historical results to each scenario. The bridge should identify changes in volume, pricing, staffing, expenses, shared costs, and service mix. This makes the earnout understandable to the owner and exposes assumptions that a headline projection conceals.
Here is an illustrative example. Assume an illustrative one-year earnout uses adjusted operating earnings above an illustrative $2.0 million threshold, pays 40 percent of the excess, and is capped at an illustrative $600,000. Assume, solely for illustration, that the calculation uses the same accounting rules in all cases and includes no other offsets. In an illustrative low case of $1.8 million, the metric falls below the floor and the payment is zero. At an illustrative target of $2.5 million, excess earnings are $500,000; 40 percent produces an illustrative payment of $200,000. In an illustrative high case of $3.8 million, excess earnings are $1.8 million; 40 percent would produce $720,000, so the illustrative cap limits payment to $600,000. These numbers describe mechanics only, not a prediction or a market benchmark.
Ask the buyer to rerun examples when a key assumption changes. For the same illustrative formula, shifting shared costs by $100,000 could reduce the target-case metric to $2.4 million and lower the payout to an illustrative $160,000. A threshold increase or a cap reduction also changes the outcome even if the operating forecast remains unchanged. Scenario tables can reveal a steep cliff where a small miss eliminates payment, or a cap that makes extra performance valuable primarily to the buyer. If the formula pays in steps, ask for cases just below and above every step.
Discuss probability as well as arithmetic. The owner can use internal operating data and professional advisers to assess whether the scenarios are credible, but should keep the assumptions separate from contractual guarantees. Ask what must be true to reach the target, which factors are under buyer control, and how much cushion exists for ordinary disruptions. A target case based on perfect staffing, immediate integration, and no collection delays may be a poor basis for valuing contingent consideration. The purpose of the scenarios is to stress-test the formula, not to make the buyer promise a forecast.
Set reporting and payment rules
The agreement should establish recurring reports during the measurement period, not merely a calculation delivered after the seller has lost practical visibility. Specify report frequency, contents, delivery deadlines, and named contacts. Useful information may include the metric calculation, supporting ledger detail, adjustments, and a comparison with the agreed baseline. Reporting lets the seller spot a classification issue while records are available and allows the parties to correct a misunderstanding before it compounds.
Define access to supporting books and records, subject to sensible confidentiality and security rules. State whether the seller or a qualified representative can inspect relevant records, ask questions, and receive reasonable copies. The right should extend to records held by an affiliate or central finance team when those records affect the calculation. Set retention requirements that cover the full review and dispute period. A calculation right without access to underlying records provides little ability to verify the result.
Create a calculation and objection timetable. For example, the buyer may deliver a statement within a set number of days after period-end, the seller may have a stated review window, and the parties may have a negotiation period before referring unresolved accounting items to an independent accountant. Specify the accountant's scope, how the parties divide fees, whether the decision is binding, and how the accountant handles items outside the submitted dispute. The accountant should apply the contract definitions instead of invent new business terms. Include a process for preserving disputed amounts while the review proceeds.
Payment terms deserve the same precision as the formula. State when an undisputed amount is due, how interest applies to late payments, whether amounts are paid in cash, and what security, if any, supports the obligation. Determine whether the buyer may set off indemnity claims, debt, or alleged breaches against an earnout. Broad unilateral offset rights can turn an otherwise earned payment into bargaining power in a separate disagreement. If offsets are allowed, define the permitted categories, notice requirements and evidence. Set a process for disputed claims. Consider treatment on resale, restructuring, insolvency, or a transfer of the acquired operations.
Compare expected value with certain cash
Use a simple comparison instead of treating the earnout's maximum as equivalent to cash. Estimate several outcomes and assign probabilities only as working assumptions, not as promised results. For each case, calculate the payment under the legal formula, then account for the delay until payment, the chance of dispute or nonpayment, and any direct costs of meeting the conditions. A financial adviser can help model present value and tax treatment; counsel can review enforceability and drafting. Those questions may vary by transaction and jurisdiction.
Compare alternatives the buyer might offer: a larger fixed amount at closing, a smaller earnout with a lower threshold, an escrow with a defined release, or a seller note with clear repayment terms. Each shifts a different risk. Cash provides execution certainty but may be lower; an earnout preserves upside but exposes the seller to post-closing decisions and measurement; a note creates credit risk and repayment timing concerns. Show the amount, payment timing and conditions, plus source of risk side by side.
Execution certainty has economic value. A buyer with financing, approvals, and a credible closing plan may provide a more reliable fixed payment than a buyer offering a higher contingent ceiling whose transaction itself remains uncertain. Evaluate whether the buyer has resources to pay the earnout, whether the obligation survives a sale or reorganization, and whether payment depends on the buyer's continued operation of the acquired business. A contingent promise from a thinly capitalized entity may be worth less than its formula suggests. Guarantees, security, or parent liability can improve collectability, but each must be negotiated and documented.
Keep the earnout separate from headline valuation when communicating internally. Track guaranteed proceeds, contingent proceeds under each scenario, and amounts at risk from operating control or collection. Do not count the same value twice through an earnout, rollover equity projection, and a seller's estimate of future employment compensation. This disciplined comparison helps the owner decide whether the proposal compensates fairly for the risk and continued attention it requires.
Avoid common mistakes and negotiate a usable agreement
A frequent mistake is accepting a broad metric with a persuasive label. "Revenue," "profit" and "adjusted earnings" can all change with the definitions. Spell out allocations and timing, plus accounting treatment. Another is focusing on the maximum while ignoring the floor and cap, or the likelihood of reaching each payout band. A third is agreeing to buyer control without reporting rights or rules that preserve a way to calculate what the acquired practice produced.
Owners can also overlook employment conditions, offsets, integration plans, or the effect of a later sale. They may assume a buyer's forecast is a contractual commitment, or accept a one-time calculation without access to source records. Some sellers negotiate a detailed formula but leave the dispute mechanism vague, so an argument over a small accounting item can delay the entire payment. Others agree that a buyer can make "reasonable" allocations without defining a method, documentation, or review process.
Before signing, give advisers the purchase agreement, earnout schedule, financial model and definitions, plus any employment or transition documents for a coordinated review. Ask transaction counsel and a tax adviser to evaluate the terms in the context of the full deal. Confirm that each negotiated protection appears in the operative agreement and that cross-references, timelines plus formulas agree. A spreadsheet or presentation may explain the business understanding, but it does not replace the signed contract.
Action checklist
Before accepting an earnout proposal, the owner should be able to answer the following questions in plain language:
- What exact metric is measured, which records govern it, and how are adjustments defined?
- What is the baseline, measurement period, threshold, payout curve, and maximum payment?
- Which buyer decisions can change the metric, and what rules preserve fair measurement?
- Do low, target plus high examples use the actual proposed formula and show assumptions?
- What reports, record access, review windows, and independent dispute process are available?
- When is an undisputed payment due, what offsets are allowed, and what protects collection?
- How does the contingent amount compare with cash and other fixed or deferred consideration?
- Have transaction counsel and tax advisers reviewed the complete agreement and related documents?
If any answer depends on an informal assurance, revise the documents before relying on it. A workable earnout gives both sides a shared method to measure performance, a practical way to check the calculation, and a payment obligation that remains meaningful after control of the practice changes hands.
