What is earnout?

An earnout is a contractual agreement in an acquisition where a portion of the purchase price is contingent on the acquired business achieving specific financial or operational milestones after the sale.

For buyers and founders looking to sell, understanding earnouts is critical because they bridge valuation gaps and incentivize seller cooperation post-acquisition. Buyers often propose earnouts when there's uncertainty about future performance, or when a significant portion of the business value is tied to intangible assets or the seller's continued involvement. For sellers, an earnout can mean a higher total payout, but it also ties a significant part of their proceeds to future performance metrics, effectively keeping them 'in the game' longer.

Earnouts are typically structured around clear, measurable targets like revenue, EBITDA, SDE, or customer retention over a specified period, often 1-3 years. The key is to define these metrics precisely within the asset purchase agreement or stock purchase agreement to avoid disputes. A common misconception is that an earnout guarantees a higher sale price; rather, it often shifts risk from the buyer to the seller, and poor post-acquisition performance can result in a smaller-than-anticipated final payout. Buyers must also consider how their operational changes might impact the seller's ability to hit earnout targets, which can lead to friction.

The 2026 market sees earnouts as increasingly common for main street and lower-middle market deals, especially for businesses with strong growth trajectories or those heavily reliant on the founder's personal sales and relationships. For founders validating startup ideas, an earnout structure can sometimes be an attractive exit path if their growth projections are ambitious but not yet fully realized. It allows them to demonstrate future value rather than selling purely on historical SDE or EBITDA multiples where their growth might not be fully reflected. Due diligence is essential to identify if an earnout is suitable, and robust legal documentation is paramount for both parties to protect their interests.

Worked example

A founder of a niche e-commerce brand selling for $1.5 million agrees to an earnout. The buyer pays $1 million upfront, with an additional $500,000 contingent on the brand achieving $2 million in gross revenue within 18 months, or 20% year-over-year SDE growth in the first post-acquisition year. If the brand hits these targets, the founder gets the full $500,000; otherwise, the payout is pro-rated or forfeited. This incentivizes the founder to assist with the transition and ensures continued strong performance.

Frequently asked questions

What are common earnout metrics?

Common earnout metrics include gross revenue, net profit, EBITDA, SDE (Seller's Discretionary Earnings), customer retention rates, or achieving specific product development milestones. The choice of metric depends heavily on the business type and what drives its value.

How can I protect myself as a seller with an earnout clause?

As a seller, protect yourself by negotiating clear, measurable, and achievable targets, defining operational covenants (e.g., buyer can't change pricing or marketing in ways that hinder targets), and potentially including a 'run-rate' or 'change of control' clause for unforeseen events. Legal counsel is essential.

From a buyer's perspective, what are the risks of an earnout?

For buyers, risks include potential disputes over target achievement, the seller's continued influence or reduced cooperation after closing, and complex accounting/reporting requirements. It's crucial to have very precise, unambiguous language in the earnout agreement to mitigate these.

Can earnouts be used in all types of business sales?

While common, earnouts are most practical in businesses where future performance is predictable or heavily influenced by the seller's continued involvement. They are less common in distressed sales or situations where the buyer plans immediate, radical operational changes that would invalidate historical performance as a baseline.
