What Is an Earnout in a Business Sale? Guide
When a buyer and founder disagree about what a business will be worth after closing, the deal does not always have to stop there. An earnout can bridge part of that gap, but it also transfers some payment risk into the post-close period, when the buyer may control the business and its reporting.
What is an earnout in a business sale? It is contingent deferred consideration: part of the seller's payment is held back and becomes payable only if agreed performance targets or other milestones are met after closing. The target may involve revenue, EBITDA, another KPI, or a defined non-financial result. An earnout is not the same as rollover equity, an escrow or indemnity holdback, or ordinary employment compensation.
For a founder-led seller, the headline purchase price is only one part of the analysis. The definition, measurement rules, operating constraints, reporting rights, payment timing, and dispute process can determine whether the contingent amount is realistic and collectible. Those issues should be evaluated alongside the broader business sale process and deal terms.
What Is an Earnout in a Business Sale?
An earnout is contingent deferred consideration: part of the seller's purchase price is paid after closing only if the acquired business meets agreed post-closing performance conditions. It lets a buyer and seller bridge a valuation gap when they have different expectations about the company's future results, rather than forcing either side to accept the other's forecast in full.
In practice, the buyer pays an upfront amount at closing and commits to potential additional payments tied to specified revenue, EBITDA, or other operational targets during a defined period. The earnout terms should identify the performance measure and how it will be determined. The parties may also need to address how business decisions and accounting treatment affect the measurement. These are negotiated deal terms, not universal features of every sale. For a broader view of where structure and negotiation fit, see the business sale process and deal terms.
How an earnout differs from other post-closing arrangements
- Rollover equity:
The seller reinvests part of the proceeds into an ownership interest in the buyer or continuing business. Its value depends on that equity investment, not simply on a defined performance-based payment.
- Escrow or an indemnity holdback:
Funds are withheld to support specified representations, warranties, or indemnity obligations. This is risk protection for potential claims, not additional consideration earned by reaching operating targets.
- Employment compensation:
Salary, bonus, or other pay is compensation for services. An earnout is purchase-price consideration tied to the agreed transaction conditions, although poorly separated terms can create legal or tax complications.
The key question is therefore not just whether more money may be paid later. It is what event or performance measure makes that payment due, how the measure will be calculated, and whether the agreement clearly separates purchase price from ownership, claim protection, and compensation.
Why Buyers and Sellers Use Earnouts
Buyers and sellers may approach the same earnout from opposite sides of a transaction. A seller may believe the business will achieve stronger results than the buyer is willing to value at closing. The buyer may see that future performance as uncertain and prefer to pay additional consideration only if agreed conditions are met. In that sense, an earnout can bridge a valuation gap while allocating some performance risk after closing. It is not a guaranteed payment or a universal feature of a business sale.
For owners evaluating a possible transaction, the proposed earnout should be considered alongside the broader sell-side process and deal terms. The headline purchase price alone does not show how much value is certain at closing, how much depends on future performance, or who controls the decisions that affect the measurement.

Buyers may use an earnout to:
Defer part of the consideration until the acquired business reaches agreed performance levels, providing some protection if projected results do not materialize.
Align the seller's expectations about future performance with the buyer's willingness to pay for that performance.
Encourage continuity and focus during a defined post-close period when the seller remains involved or has useful operating knowledge.
Manage uncertainty without treating an optimistic forecast as guaranteed value at closing.
Sellers may accept an earnout to:
Preserve the opportunity to receive additional consideration when the business performs as the seller expects.
Address a gap between the seller's valuation and the buyer's initial offer without ending negotiations immediately.
Demonstrate confidence in the business's prospects, provided the targets and measurement rules are realistic and clear.
Support a transition in which the seller's knowledge helps protect customer relationships, employees, or operations after closing.
The alignment can weaken when the buyer controls spending, staffing, pricing, or other decisions that influence the earnout metric. A buyer might invest in additional staff, reducing short-term profit while pursuing a longer-term gain. Conversely, an earnout can encourage short-term choices, such as reducing marketing spending or margins to improve the measured result. These competing incentives should be addressed in the agreement rather than assumed away.
How Earnout Metrics and Payments Are Structured
The metric is the engine of an earnout. The purchase agreement should state precisely what is measured, during which period, and how the result translates into a payment. Revenue may be useful when sales growth is the central objective. EBITDA may be more relevant when profitability matters. Other KPIs or operational milestones can apply when the value-creating event is customer retention, a technical achievement, market acceptance, or regulatory approval.
Metric selection should connect to the parties' agreed view of value, not simply use the easiest number to report. Sellers should also understand how the metric relates to the business valuation and deal structure. The agreement should address thresholds, caps, and whether performance is measured on a straight-line basis, in tiers, or only after a minimum level is reached. A threshold can mean that performance below the agreed level produces no earnout, while a cap limits the maximum payable amount.
Common earnout design choices
Design element | What it controls | Question to resolve |
Performance metric | Revenue, EBITDA, another KPI, or an operational milestone | What result best reflects the value being transferred? |
Measurement period | The time window in which performance counts | Is the result measured annually, cumulatively, or by milestone date? |
Threshold and cap | When payment begins and where the obligation ends | What happens below the threshold, and what is the maximum payment? |
Reporting and payment | How results are delivered, reviewed, and paid | When does the buyer provide the statement, and when is payment due? |
The measurement period is part of the economics and should be set according to the transaction's goals, the metric being measured, and the parties' negotiated risk allocation. Payment is often made after the relevant period once the metric is calculated. The agreement should identify reporting deadlines, supporting records, review rights, and the process for challenging a calculation. It should also explain the accounting policies used for revenue, EBITDA, or other measures, since changes in classification or treatment can alter the result.
For a concrete example, an SEC-filed agreement sets annual revenue measurements and requires an earnout statement within ninety days after each fiscal year. It includes annual and aggregate caps and provides a process involving an independent CPA or arbitrator if the parties cannot resolve a dispute: SEC-filed earnout agreement. This is an example of drafting detail, not a universal template. The parties should tailor the formula, reporting obligations, and payment timing to the transaction and obtain appropriate professional advice.
What Should an Earnout Agreement Define?
An earnout should be drafted so both parties can tell, before closing, how performance will be measured and what happens when the business changes. The purchase agreement should do more than state a target. It should reduce room for conflicting interpretations while recognizing that the buyer will operate the company after the sale.
Define the metric and accounting rules
Start with the performance measure: revenue, EBITDA, another KPI, or a defined operational milestone. Then define every material term used in the formula. If the metric is revenue, address items such as recognized sales, returns, credits, acquisitions, and discontinued operations when relevant to the deal. If it is profit or EBITDA, specify the accounting policies, adjustments, allocations, and treatment of extraordinary items that apply. The parties can use established accounting standards, but the agreement should identify which rules control if the buyer's and seller's normal practices differ. This is a negotiation point, not a universal drafting formula. Negotiating terms in the LOI can help establish the commercial framework before detailed drafting.
Set the opening position and operating expectations
The opening balance sheet matters because errors in that starting position can affect earnings measured during the earnout period. Decide whether the parties may review or amend it, and whether it should align with completion accounts. The agreement should also address operating covenants: for example, how the buyer may change budgets, pricing, staffing, shared costs, customers, or accounting systems. These provisions need to balance the buyer's authority to run the business with a seller's legitimate concern that avoidable changes could affect the metric.
Build a reporting and review process
Specify the measurement periods, reporting deadline, supporting records, payment date, and the seller's access to relevant information. A filed SEC agreement illustrates the level of detail parties sometimes use: it provides for an earnout statement after each fiscal year, annual measurement, and a defined post-closing revenue measure. It is an example of drafting, not a universal template. Review the SEC-filed agreement for that illustration.
Plan for disagreements and a change of control
Include a notice and objection process, deadlines for exchanging calculations, and a neutral decision-maker if the parties cannot agree. Some agreements use an independent CPA or arbitrator for calculation disputes. Also discuss what happens if the buyer resells the company before the earnout ends. The parties may negotiate acceleration or another treatment, but neither approach is automatic. Because these provisions affect legal rights, accounting interpretation, and transaction risk, sellers should involve M&A legal counsel for sellers before accepting final language.
What Are the Risks of an Earnout for a Seller?
An earnout can bridge a valuation gap, but it also leaves part of the seller's consideration dependent on events after closing. That uncertainty matters because the buyer typically controls the business during the measurement period, while the seller may still be evaluated against targets shaped by decisions the seller no longer controls.
Performance can miss the target for reasons beyond the seller's control
Revenue, EBITDA, retention, or another agreed milestone may fall short even when the seller believes the business is fundamentally healthy. A buyer may change pricing, staffing, marketing, integration plans, or investment priorities. For example, hiring additional staff can reduce short-term profit while supporting a longer-term gain, which may affect an earnout tied to near-term profitability. The agreement should therefore address how operational decisions are made and how their effects are measured.
Accounting rules and reporting can create disputes
Small differences in accounting policies, adjustments, the opening balance sheet, or the treatment of shared costs can change the measured result. A dispute can also consume attention during the earnout period and damage performance while the parties are still relying on one another. That is why accounting rules and operating terms deserve careful drafting.
Incentives and employment conditions need separate analysis
An earnout may encourage short-term decisions, such as reducing marketing or margins to improve a near-term metric, even when those choices weaken longer-term value. Some agreements also connect payment to continued employment or service. That condition is not the same as a performance condition, and it can affect both the seller's practical control and the legal or tax treatment. Treatment depends on the facts and jurisdiction, so qualified legal and tax advisers should review the language.
Finally, an earnout is not rollover equity or a holdback. Rollover equity gives the seller an ownership interest in the buyer or continuing business; an earnout is contingent additional consideration tied to agreed performance. An escrow or indemnity holdback generally reserves part of the purchase price for specified claims, rather than rewarding post-closing results. Keeping those mechanisms distinct helps a seller compare payment certainty, control, upside, and risk before accepting the structure.
Where Does an Earnout Fit in the M&A Process?
An earnout is not a separate stage of a business sale. It is a contingent deal term that develops alongside valuation, negotiation, documentation, and post-closing measurement. The earlier both parties identify the issue, the easier it is to test whether the proposed metric and operating assumptions are workable.
Valuation and exit readiness:
Begin by assessing whether the seller's expectations and the buyer's view of future performance differ. An earnout may help bridge that gap, but it should be evaluated alongside the broader valuation and deal structure. Owners can use this
to organize readiness questions before marketing begins.
- Confidential marketing materials and buyer outreach:
The seller's financial information, growth assumptions, and operational story appear in confidential buyer materials. Those materials may inform earnout discussions, but a preliminary indication is not a completed earnout formula. Buyer conversations help reveal which future milestones are credible and measurable.
Letter of intent:
If the parties are considering contingent consideration, the LOI should address the principal economics and commercial intent, including the metric, measurement period, control assumptions, and payment framework. This is the point to
, while recognizing that detailed drafting remains ahead.
- Diligence and definitive agreement:
During diligence, the parties test the forecast, opening financial position, reporting data, and proposed accounting rules. The definitive agreement then specifies how performance is calculated, reported, reviewed, and disputed. It should also address events such as a change in control or an early end to the measurement period.
Closing and post-close measurement:
At closing, the earnout becomes part of the binding transaction documents, but it is not necessarily payable then. After closing, the buyer operates the business and the agreed measurement process determines whether a payment is due. For a differentiated sector example, review these
; healthcare transactions may involve additional applicable requirements. The broad process remains the same: define the terms carefully, document the baseline, and measure performance under the agreement.
Frequently Asked Questions
How does an earnout agreement work?
An earnout agreement makes part of the purchase consideration contingent on specified results after closing. It should define the metric or milestone, measurement period, reporting method, payment date, caps or thresholds, and how disagreements will be resolved. The buyer operates the acquired business, while the agreement sets the rules for measuring whether additional consideration is due.
What is a typical earnout percentage?
There is no universal earnout percentage. The amount depends on the valuation gap, how measurable the target is, the buyer's control after closing, the seller's continuing role, and the parties' risk tolerance. Instead of relying on a market percentage, compare the proposed contingent amount with the total consideration and test whether the targets are realistically achievable under the buyer's planned operating decisions.
Is an earnout considered debt?
An earnout is generally contingent purchase consideration, not automatically a fixed debt obligation. Whether a particular payment is treated as debt, contingent consideration, compensation, or another category can depend on the transaction documents, payment terms, accounting framework, and facts. The parties should have transaction counsel and accounting advisers review the structure rather than assume one classification applies everywhere.
Are earnouts taxed as capital gains?
Tax treatment is not automatic. An earnout may be analyzed differently depending on the jurisdiction, the sale structure, the connection between payment and employment, and whether the amount is contingent or fixed. Sellers should ask qualified tax advisers to review the purchase agreement and their individual circumstances before signing, because an answer that fits one transaction or jurisdiction may not fit another.
What are examples of earnout structures?
Common structures tie additional consideration to financial measures such as revenue or EBITDA, operating milestones, or a combination of targets over a defined period. A well-drafted structure also explains accounting policies, reporting access, buyer operating obligations, payment timing, and dispute procedures. The right design depends on what the seller can influence and what the buyer can measure consistently after closing.
