Key Takeaways
- The earnout metric definition must be as precise as a revenue recognition policy in an audited financial statement. A broad reference to "EBITDA" or "revenue" without further specification is a guaranteed dispute at measurement time.
- The accounting standard used to measure the earnout metric must be specified at signing. Whether GAAP or the seller's historical methodology applies determines the outcome of every edge case at measurement time.
- Operational covenants protecting the seller during the earn period must be negotiated before signing. A buyer who integrates the acquired business, changes pricing, or reallocates customers post-close can reduce the earnout metric without any legal claim by the seller unless specific covenants prohibit those changes.
- Acceleration clauses and a defined dispute resolution mechanism must be included in the APA before signing. Negotiating either after closing is not possible.
An earnout is a deferred purchase price mechanism that bridges the valuation gap between what a seller believes the business is worth and what a buyer is willing to pay at closing. The buyer pays a base amount at close and an additional amount post-closing if the business hits agreed performance targets. The structure is common in small business acquisitions where the seller's forward projections are optimistic and the buyer cannot verify them with a short due diligence period.
In theory, earnouts align incentives and make deals possible that could not otherwise close. In practice, they generate significant post-closing disputes when the APA does not specify every element of the earnout with precision. Nearly every earnout dispute is traceable to a provision that was vague or missing at signing. This checklist covers what the APA must spell out before the deal closes. For what happens when disputes arise despite good drafting, see our guide on earnout dispute resolution.
Metric Definition: How Specific Is Specific Enough
The earnout metric definition needs to be as precise as the revenue recognition policy in an audited financial statement. For revenue-based earnouts, the definition should specify: (1) when revenue is recognized (at delivery, at invoice, at cash receipt); (2) how customer credits, returns, and allowances are treated; (3) whether intercompany revenue is included or excluded; and (4) the treatment of deferred revenue from contracts signed before or during the earn period.
For EBITDA-based earnouts, the definition must address: add-backs and exclusions by category (not just "one-time items," which is itself ambiguous); allocation of shared costs between the acquired business and the buyer's other operations; treatment of capex versus operating expenditure; and whether management fees, intercompany charges, or consulting fees paid to the buyer or its affiliates are included in the expense base.
Revenue vs. EBITDA: Relative Drafting Complexity
Accounting Standard: The Two-Sentence Fix That Prevents the Most Common Dispute
A business acquired from a founder who maintained cash-basis books will be measured differently when the buyer applies accrual GAAP. Revenue recognition timing changes. Expense accruals appear. The period-end snapshots look different even if the underlying cash flows are identical.
The APA must specify whether the earnout metric is calculated on the seller's historical accounting basis, on GAAP, or on a defined hybrid methodology. It must also require that the same standard be applied consistently throughout the earn period, regardless of changes the buyer makes to the acquired business's accounting practices post-closing. Two sentences in the APA resolve what is otherwise a guaranteed dispute the first time the buyer runs a year-end close under a different accounting system.
Post-Close Operational Covenants: Protecting the Earnout During the Earn Period
The earnout covenants are the seller's primary protection against buyer decisions that reduce the earnout metric during the earn period. These are affirmative and negative obligations that restrict the buyer's operational discretion. Sellers should negotiate for, at minimum, the following covenants in every earnout deal:
- Sufficient funding obligation: The buyer must provide the acquired business with adequate resources, including working capital, personnel, and marketing budget, to operate at historical levels during the earn period.
- No diversion of opportunities: The buyer cannot redirect customers, contracts, or business opportunities from the acquired entity to a related entity if doing so reduces the earnout metric.
- Preservation of business identity: The buyer cannot dissolve, merge, or substantially restructure the acquired entity without seller consent during the earn period.
- Key management continuity: If the seller is remaining post-close in an operating role, the buyer cannot terminate the seller's involvement in a way that damages the business's performance and the resulting earnout metric.
- Intercompany pricing at arm's length: Any transactions between the acquired business and the buyer's other entities must be priced at fair market value and cannot be used to shift revenue or costs in a way that affects the earnout calculation.
Buyers often resist specific covenants as constraining legitimate business judgment. The negotiation trades buyer flexibility against seller payment certainty. When the earnout represents more than 20 percent of total deal value, sellers have stronger grounds to insist on detailed operational covenants.

Acceleration: What the APA Must Include for a Business Sale During the Earn Period
Without an acceleration clause, a buyer who acquires a business with an earnout and then sells that business to a third party within the earnout window has no obligation to make earnout payments that were not yet earned. The seller's earnout claim against the original buyer may be meaningless if the original buyer no longer controls the business, and the new buyer has no obligation to the original seller absent an assumption of the earnout.
An acceleration clause solves this by treating a change of control of the buyer or a sale of the acquired business as a triggering event that makes the full remaining earnout immediately payable. Sellers should negotiate acceleration on two triggers: a sale of the acquired business to a third party, and a change of control of the buyer itself (in case the buyer is acquired and the new owner has different operational plans).
Buyers resist broad acceleration clauses because they can create material contingent liabilities in the buyer's own future transactions. The negotiated middle ground is often a partial acceleration, where a portion of the remaining earnout is paid immediately upon a qualifying event, with the remainder continuing on the original schedule under the new owner's control.
Dispute Resolution: What the APA Must Specify Before Signing
The earnout dispute resolution mechanism is almost as important as the metric definition. The APA should specify a two-step process: a good faith negotiation period (typically 30 to 60 days) followed by binding resolution by an independent accountant or accounting firm for measurement disputes. Non-measurement disputes, typically those involving alleged covenant breaches, should go to arbitration or litigation under a separately specified forum.
The APA must specify: who pays for the independent accountant (commonly allocated based on the outcome or split equally); the selection process if the parties cannot agree on a firm; the standard of review (the accountant resolves accounting disputes, not legal disputes about the scope of the earnout definition); the timeline from dispute notice to final determination; and whether the accountant's determination is final and binding or subject to limited appeal.

Frequently Asked Questions
What must the APA specify about the earnout metric?
The APA must define the earnout metric with the same precision used in audited financial statements. For revenue-based earnouts, the definition must specify when revenue is recognized, how returns and allowances are treated, whether intercompany revenue is included or excluded, and how deferred revenue is handled. For EBITDA-based earnouts, the definition must address add-backs and exclusions by category, allocation of shared costs from the buyer's other operations, treatment of capex versus operating expenditure, and whether management fees or intercompany charges are included. A broad reference to "EBITDA as customarily calculated" is not sufficient and will produce a dispute at measurement time.
Which accounting standard applies to an earnout metric?
The APA must specify whether the earnout metric is calculated using GAAP, the seller's historical accounting methodology, or a hybrid standard defined in the APA itself. If this is not specified, the buyer may switch from the seller's cash-basis accounting to accrual GAAP post-closing, which changes revenue recognition timing and expense accruals even if underlying cash flows are identical. Two sentences in the APA specifying the applicable accounting standard and requiring consistent application throughout the earn period prevent the most common accounting-standards disputes in earnout calculations.
What operational covenants should a seller require in an earnout APA?
Sellers should require, at minimum: a sufficient funding obligation requiring the buyer to provide adequate working capital and personnel during the earn period; a prohibition on diverting customers or business opportunities from the acquired entity to related entities; a preservation covenant preventing the buyer from dissolving or substantially restructuring the acquired business without seller consent; a key management continuity provision if the seller remains post-close; and an arm's-length pricing requirement for intercompany transactions that could shift costs and affect the earnout metric. Without these covenants, the buyer retains broad discretion to make operational decisions that reduce the earnout metric without any legal claim by the seller.
What is an acceleration clause and when should it be included in an earnout?
An acceleration clause provides that the full remaining earnout amount becomes immediately payable upon a specified triggering event, typically a sale of the acquired business to a third party or a change of control of the buyer. Without an acceleration clause, a buyer who sells the acquired business during the earn period may eliminate future earnout obligations if the new owner does not assume them. Sellers should negotiate acceleration on two triggers: a sale of the acquired business and a change of control of the buyer itself. Buyers typically accept partial acceleration as a compromise, where a portion of the remaining earnout is paid immediately with the balance continuing on the original schedule.
How should the APA define the earnout dispute resolution process?
The APA should specify a two-step dispute resolution mechanism: a good faith negotiation period, typically 30 to 60 days from the date a party delivers a dispute notice, followed by binding resolution by an independent accountant for measurement disputes and arbitration or litigation for covenant disputes. The APA must also specify the accountant selection process if the parties cannot agree, the standard of review, the timeline from dispute notice to final determination, the allocation of fees, and whether the accountant's determination is final and binding. A well-drafted dispute resolution mechanism keeps earnout disputes out of court and resolves accounting questions on the merits rather than through litigation leverage.
