Earnouts are one of the most misunderstood and most contentious elements of any M&A transaction. For founders, they represent an opportunity to capture additional value beyond the closing price — provided the business hits agreed targets after the sale. For buyers, they are a risk management tool that bridges valuation gaps and aligns seller incentives with post-closing performance.
In practice, earnouts are significantly more complex than either party anticipates at the term sheet stage. Understanding the mechanics, the risks, and the negotiating points before you agree to one is essential.
WHAT IS AN EARNOUT?
An earnout is a contingent payment mechanism in which part of the purchase price is paid after closing, conditional on the business achieving specified financial or operational targets over a defined period. A typical earnout might be structured as: $10 million at closing, plus up to $5 million over two years if the business achieves agreed revenue or EBITDA targets.
Earnouts are most commonly proposed by buyers when there is a valuation gap — when the seller's expectations exceed what the buyer is willing to pay based on current financial performance. The earnout defers a portion of the valuation risk to the seller.
WHEN EARNOUTS MAKE SENSE — AND WHEN THEY DO NOT
Earnouts make sense when the business has genuine near-term growth catalysts that are not yet reflected in historical financial performance — a new product about to launch, a large contract recently signed, or a market expansion underway. In these cases, the earnout allows the seller to capture the value of growth that the buyer is not willing to pay for upfront.
Earnouts make less sense when the seller is exiting operationally. If you are stepping back from day-to-day management at closing, your ability to influence the earnout outcome diminishes significantly. A buyer who makes post-closing decisions that negatively affect revenue — changing pricing, cutting the sales team, or pivoting the product — can destroy an earnout without breaching its terms.
In cross-border transactions, earnouts add an additional layer of complexity. Currency fluctuations, different accounting standards in the operating jurisdiction, and regulatory changes can all affect the earnout calculation in ways that have nothing to do with business performance.
THE MOST IMPORTANT EARNOUT NEGOTIATING POINTS
The metric. Revenue-based earnouts are simpler and easier for sellers to influence than EBITDA-based earnouts. EBITDA can be affected by cost allocation decisions the buyer controls — overhead charges, management fees, and shared service allocations. If the earnout is EBITDA-based, cap the buyer's ability to allocate costs to the earnout-period business.
The measurement period. Shorter is better for sellers. A two-year earnout is preferable to a three or four year earnout. The longer the period, the more opportunity for the buyer to make decisions that affect the outcome.
Operating covenants. The most important protection in any earnout agreement is a set of operating covenants that restrict the buyer's ability to make decisions that negatively affect earnout performance. These should include restrictions on changing the sales team, altering pricing materially, reducing the marketing budget, or redirecting customers to other parts of the buyer's business.
Acceleration provisions. Negotiate for acceleration of the earnout if the buyer exits the business, takes it private, or sells it during the earnout period. Without acceleration, a change of control during the earnout period can leave the seller with no recourse.
THE REALITY OF EARNOUT DISPUTES
Earnout disputes are among the most common and most expensive forms of post-closing M&A litigation. The fundamental problem is that buyer and seller have conflicting interests during the earnout period — the buyer is managing the business for their long-term objectives, while the seller is managing for short-term earnout metrics.
The best protection against earnout disputes is precise drafting of the earnout agreement — clear definitions of every metric, clear accounting policies for measurement, and clear dispute resolution mechanisms. This requires an experienced M&A attorney and a financial advisor who understands how the numbers will be calculated.
CONCLUSION
Earnouts can be the right structure in the right situation. They can also be a mechanism through which sellers receive significantly less than the headline price suggests. Negotiate them carefully, with experienced advisors, and with a clear understanding of what you can and cannot control after closing.
