What Should Sellers Negotiate Before Accepting an Earnout?

Start with the economic metric, not the headline payout

An earnout should begin with a precise statement of what creates a payment. Common measures include revenue, gross profit, EBITDA, customer retention, product milestones, or a specified transaction event. The term should identify the measurement period, threshold, payment curve, caps, floors, and whether results are measured annually, cumulatively, or by separate tranche. Avoid a formula that depends on undefined phrases such as normal operations, commercially reasonable efforts, or customary expenses unless the agreement explains how those phrases will be tested.

Ask whether the metric tracks the value you are being asked to leave behind. A revenue target may be affected by pricing and product mix. EBITDA may be affected by overhead allocations, acquisition costs, executive compensation, intercompany charges, and accounting changes. A milestone may depend on a regulator, customer, or third party that neither side controls. The negotiation should identify which variables are within the buyer's control and what happens when an outside event prevents a fair measurement.

Define accounting rules and preserve consistency

The calculation section should state the accounting principles, policies, exclusions, and adjustments that apply. If the metric is EBITDA, define each add-back and deduction instead of assuming the parties share one definition. State how one-time items, new locations, discontinued operations, acquisitions, foreign exchange, allocation of corporate costs, and changes in accounting methods are treated. A seller should also ask whether the buyer must keep books for the acquired business separately enough to reproduce the calculation.

The IRS describes a contingent payment sale as one in which the total selling price cannot be determined by the end of the sale year, including a business sale tied to future profits. It says different rules may apply to the contract price and gross profit percentage, and business-sale allocations can affect reporting. [1] That is a tax framework, not a conclusion about your transaction. Have a qualified tax adviser review the purchase-price allocation, payment characterization, withholding, and reporting consequences before signing.

Negotiate operating covenants and control limits

A buyer usually needs flexibility to run the acquired business, but an unrestricted right to redirect sales, costs, staff, customers, or investment can make the earnout illusory. Negotiate a balanced operating covenant that identifies prohibited conduct, required cooperation, and commercially reasonable protections for the measurement. Possible subjects include moving revenue between entities, changing pricing or credit terms, diverting leads, stopping a product, changing sales compensation, loading shared costs, or combining the business with another operation.

Do not assume a general promise to operate in good faith answers every scenario. The agreement can specify notice rights, a process for resolving proposed changes, and an adjustment method when the buyer takes an action that materially affects the formula. It can also define which decisions remain solely with the buyer. The goal is not to freeze the business. It is to make the economic bargain measurable when the buyer's post-closing control changes the inputs.

Secure records, reports, and review rights

A workable earnout gives the seller enough information to test the calculation without turning the seller into the operator. Negotiate the report contents, delivery date, supporting schedules, access to relevant books and records, and the people who can answer questions. Specify whether the seller may use an independent accountant or other representative, subject to reasonable confidentiality requirements. Identify the source-of-truth records, such as the general ledger, customer reports, invoices, contract data, and allocation schedules.

A filed earnout agreement illustrates why these mechanics matter: the buyer delivered a report tied to audited financial statements, described the EBITDA computation, allowed questions to be raised with accountants and employees, and imposed a written objection deadline. [2] That agreement is transaction-specific, so it should be used as a checklist rather than copied as a universal term. Ask for enough time to review the data and for a process that does not make silence an accidental waiver.

Set deadlines, objections, and the dispute ladder

The agreement should state when the buyer must calculate and pay, when the seller may object, what an objection must contain, and what happens next. A useful process separates informal questions from a formal objection, then provides a short good-faith negotiation period and an independent accounting or expert review for unresolved calculation disputes. Define the expert's authority, permitted evidence, confidentiality, decision deadline, allocation of fees, and whether the decision is final except for defined errors or misconduct.

The dispute process should match the dispute. An accounting expert may be appropriate for a formula application, while a court or arbitrator may be needed for broader contractual conduct. One SEC-filed agreement limited the expert's review to disputed items and required a written determination based on the agreement's standards. [3] Negotiate whether the expert may choose any number or only an amount within the parties' submitted ranges, and preserve claims for fraud or intentional misconduct where applicable under the governing law.

Address payment protection and set-off

An earned amount is different from a collectible amount. Negotiate payment timing, interest on late payments if appropriate, escrow or credit support where justified, and the effect of an indemnity claim. If the buyer can set off alleged losses against an earnout, require written notice, a defined claim process, limits on withholding, and payment of any undisputed balance. Clarify what happens if financial statements are later restated and whether a repayment obligation has a time limit.

Set-off language can materially change risk. A filed agreement permitted withholding against an earnout for specified indemnity claims and later payment of any remaining balance after final resolution. [2] Another filed agreement included advance notice before set-off against contingent consideration and described how shortfalls would be paid after the earnout determination. [3] These examples show issues to negotiate, not rights that automatically apply to every seller.

Coordinate tax, accounting, and employment terms

Earnouts can touch more than the purchase agreement. The purchase-price allocation, installment reporting, interest, withholding, and characterization of payments should be reviewed with tax advisers. The accounting treatment can also depend on the exact arrangement and the buyer's reporting framework. FASB's 2025 guidance includes an example of an earnout based on EBITDA tied to products using an acquired patent, while analyzing whether a contract falls within a derivatives scope exception. [4] That example does not decide the accounting for your deal.

If the seller will remain employed or consulting after closing, separate compensation terms from purchase-price terms carefully. Conditions tied to continued service may create different tax, accounting, or legal consequences than a payment based only on ownership value. Employment, restrictive covenant, intellectual property, and indemnity provisions should be reviewed together so that a dispute under one document does not unexpectedly eliminate or delay the contingent payment.

Use a controlled implementation workflow

Before signing, create a one-page earnout schedule that maps each definition to a source record, owner, calculation step, review date, and escalation path. Have the seller's deal lead compare the schedule to the draft agreement line by line. Have the buyer's finance owner confirm that the proposed data can actually be produced from the ledger and operating systems. Run a dry calculation using illustrative data, label assumptions, and test boundary cases such as a result just below a threshold, a partial period, a restatement, a new business line, and a disputed cost allocation.

If software or AI is used to organize the workflow, keep it user-operated. The accountable finance or deal owner should approve the source records, permissions, formula version, and final report. Check extracted figures against the ledger and signed agreement, restrict access to confidential deal materials, and stop the pilot if records cannot be traced, calculations disagree, or reviewers cannot explain the output. No tool should send notices, negotiate terms, approve a payment, or disclose information without a human decision.
