Key takeaways
- An earnout makes part of the purchase price contingent on the business achieving defined results after closing, such as revenue, gross profit or EBITDA targets.
- Earnouts help bridge valuation gaps when buyers and sellers disagree about future performance, but they are a leading source of post-closing disputes.
- The most important protections are a precise metric definition, clear accounting rules, operating covenants, and a defined dispute resolution process.
- For financial reporting, buyers generally record earnouts at fair value on the acquisition date under ASC 805, typically using probability-weighted or simulation methods.
- The tax treatment of earnout payments depends on how they are structured. Payments tied to continued employment risk being treated as compensation rather than purchase price.
The seller believes the business is about to take off. A new product line is ramping, a major customer contract is nearly signed, and the pipeline has never been stronger. The buyer sees risk: the new product is unproven, the contract isn’t signed, and the pipeline is just a pipeline.
One way to close that gap is an earnout: the buyer pays a base price at closing and agrees to pay more later if the business performs.
Earnouts can be the difference between a deal and no deal. But they also put buyer and seller in an awkward position: the seller’s payout depends on a business the buyer now controls. This article explains how to structure an earnout that both sides can live with, and how earnouts are valued.
What an earnout is
An earnout is contingent consideration: additional purchase price payable if specified conditions are met after closing.
Example
- Base price at closing: $8,000,000
- Earnout: up to 2, 000, 000 * *,payableifrevenueinthesecondfullyearafterclosingreaches * *12,000,000, with a partial payment of 1, 000, 000 * * ifrevenuereaches * *11,000,000.
If the business hits $12 million, the seller receives $10 million in total. If it falls short of $11 million, the seller receives $8 million.
Why buyers and sellers use earnouts
- Bridging a valuation gap. The seller values the company on projected growth; the buyer values it on historical results. The earnout pays for growth only if it materializes.
- Managing uncertainty. Pending contracts, regulatory approvals, product launches or recoveries from a downturn are hard to price at closing.
- Financing. An earnout defers part of the price, reducing the cash the buyer needs at closing.
- Retention and alignment. Where sellers stay on to run the business, an earnout aligns incentives, though this creates tax and accounting issues discussed below.
Choosing the right metric
The metric is the heart of the earnout. Each option has trade-offs:
| Metric | Advantages | Risks |
|---|---|---|
| Revenue | Simple, harder to manipulate through cost allocations | Buyer may pursue unprofitable revenue or shift sales; seller may chase low-margin sales |
| Gross profit | Captures pricing and direct costs | Requires clear cost-of-sales definitions |
| EBITDA / net income | Closest to value creation | Most exposed to disputes over overhead allocations, integration costs and accounting choices |
| Non-financial milestones | Clear, binary (e.g., FDA approval, contract signed) | All-or-nothing outcomes; definitions of “achieved” can still be disputed |
Many practitioners favor revenue or gross profit for sellers who will no longer control costs, and EBITDA where the seller will continue managing operations and the business remains a separate unit.
Structure: the terms that matter
Measurement period
Earnouts commonly run one to three years. Longer periods increase uncertainty and the chance of disputes as the business integrates with the buyer.
Payment formula
- All-or-nothing (“cliff”): simple but creates sharp incentives at the threshold.
- Tiered: partial payments at different levels.
- Linear: a percentage of results above a baseline, up to a cap.
Caps and floors
A cap limits the buyer’s maximum payment. A floor (or minimum payment) gives the seller some certainty.
Catch-up and carry-forward provisions
A catch-up allows a seller who misses a year-one target to earn that payment if cumulative results over two years meet the combined target.
Accounting principles
Specify that the metric will be calculated using GAAP applied consistently with the seller’s historical practices, and address specific items: – treatment of integration costs and buyer corporate overhead allocations; – intercompany pricing if the business sells to or buys from the buyer’s affiliates; – acquisitions made by the business during the earnout period; and – transaction costs and purchase accounting adjustments.
An illustrative calculation, using historical figures, attached to the agreement, can prevent many disputes.
Operating covenants
This is often the most heavily negotiated area. Sellers typically seek covenants that the buyer will: – operate the business consistently with past practice; – maintain it as a separate unit with separate books; – provide adequate capital and staffing; – not divert customers, products or opportunities to affiliates; and – not take actions intended to reduce the earnout.
Buyers resist covenants that restrict their ability to run the business they bought. A common compromise is a covenant not to take actions with the primary purpose of avoiding or reducing the earnout, combined with specific affirmative commitments.
Acceleration
Sellers often negotiate for the earnout to accelerate (become payable in full or at a set amount) if the buyer sells the business, terminates the seller without cause, materially breaches the covenants, or integrates the business so that the metric can no longer be measured.
Information rights and dispute resolution
The seller should receive periodic reports and access to books and records supporting the calculation. Disputes over calculations are often sent to an independent accountant, while disputes over covenants may go to arbitration or court.
Set-off rights
Buyers frequently seek the right to offset indemnification claims against earnout payments. Sellers should limit set-off to finally determined claims.
How earnouts are valued
Earnouts have value even before they are earned, and that value matters for several reasons: negotiating the deal, evaluating competing offers, financial reporting, and in some cases fairness or solvency analyses (see our article on fairness and solvency opinions).
Financial reporting: ASC 805
Under ASC 805, Business Combinations, a buyer reporting under U.S. GAAP generally must recognize contingent consideration at fair value on the acquisition date as part of the purchase price. If the earnout is classified as a liability (as most cash earnouts are), it is remeasured to fair value each reporting period, with changes recorded in earnings until it is settled. Equity-classified contingent consideration generally is not remeasured.
These remeasurements can create earnings volatility for the buyer and interact with goodwill and impairment testing, discussed in our article on goodwill impairment testing for private companies.
Valuation methods
Scenario-based (probability-weighted) method. For simpler or milestone-based earnouts, the analyst estimates the probability of each outcome and discounts the expected payment.
Using the earlier example, payable at the end of year two:
| Outcome | Payment | Probability | Weighted |
|---|---|---|---|
| Revenue ≥ $12M | $2,000,000 | 40% | $800,000 |
| $11M ≤ Revenue < $12M | $1,000,000 | 30% | $300,000 |
| Revenue < $11M | $0 | 30% | $0 |
| Expected payment | $1,100,000 |
Discounting 1.1millionfortwoyearsata * * 15832,000**.
So the seller’s “up to 10million” dealhasanexpectedpresentvaluecloserto * *8.8 million**, before considering the buyer’s credit risk.
Option pricing and Monte Carlo simulation. For earnouts based on financial metrics with nonlinear payoffs, such as tiers, caps, thresholds and multi-year catch-ups, analysts often use Monte Carlo simulation or option-pricing techniques. These model a range of possible outcomes, typically in a risk-neutral framework, and account for the volatility of the metric, the payoff structure and the buyer’s credit risk.
Key inputs
- management projections and their reliability;
- volatility of the underlying metric;
- correlation with market risk;
- time to payment; and
- counterparty (buyer) credit risk.
Tax considerations
Tax treatment depends heavily on structure and should be planned with tax advisors before signing.
- Purchase price vs. compensation. If earnout payments are conditioned on the seller remaining employed, they risk being treated as compensation (ordinary income to the seller, deductible to the buyer) rather than purchase price (often capital gain). The same feature generally causes the payments to be treated as post-combination compensation expense, not purchase consideration, for financial reporting.
- Installment method. Sellers may be able to report gain on earnout payments under the installment method as payments are received, subject to specific rules for contingent payment sales.
- Imputed interest. A portion of deferred payments may be treated as interest.
- Deal structure. Whether the deal is an asset or stock sale affects how earnout payments are allocated and taxed. See our article on asset sale vs. stock sale and purchase price allocation.
Tips for sellers
- Value the earnout realistically. Treat it as worth less than its face value, and negotiate the base price accordingly.
- Prefer simple, objective metrics you can monitor.
- Negotiate strong covenants, information rights and acceleration triggers.
- Avoid tying payments to employment unless that is the intent.
- Consider the buyer’s ability to pay and seek security if appropriate.
Tips for buyers
- Keep definitions tight and attach illustrative calculations.
- Preserve operational flexibility while making reasonable commitments.
- Plan for the accounting, including fair value measurement and remeasurement.
- Align earnout metrics with your integration plan so you are not forced to choose between integration and measurability.
Frequently asked questions
They are common in private-company transactions, particularly in sectors with high growth uncertainty such as technology and life sciences, and when buyers and sellers disagree about projections.
It varies widely by deal. Earnouts are usually a minority of total consideration, but can be significant where uncertainty is high.
Buyers control post-closing operations, which creates risk for sellers. Clear definitions, covenants and dispute processes reduce that risk.
Under ASC 805, contingent consideration is generally recognized at fair value at acquisition; liability-classified earnouts are remeasured each reporting period through earnings.
The bottom line
An earnout can unlock a deal that would otherwise fail, but only if it is carefully defined, realistically valued and supported by protections both sides understand. Treat the earnout as a negotiated financial instrument, not a promise.
