What is an earnout and how does it affect your sale price?

An earnout is a portion of the sale price that gets paid after closing, based on whether the business hits specific performance targets. Instead of receiving all your money at closing, you receive a base amount at close and additional payments later if the business performs the way you told the buyer it would. The earnout is the buyer’s way of saying, “We’ll pay more if it turns out to be as good as you say.”

When buyers propose earnouts

Earnouts usually come up when there’s a gap between what the buyer is willing to pay today and what you believe the business is worth. That gap often exists for a specific reason. Revenue may be growing fast and the buyer isn’t sure the trend will hold. A major customer relationship may feel uncertain to the buyer. Or the recent performance looks strong but the history is inconsistent.

In those situations, the buyer is willing to pay a higher price, just not all of it upfront. The earnout shifts some of the risk back to you. If the performance continues, you get paid. If it doesn’t, the buyer paid less than you hoped.

How earnouts are structured

A typical earnout agreement looks something like this: if the business generates at least $X in revenue (or adjusted EBITDA) in the 12 months after closing, the seller receives an additional $Y. The target, the metric, the measurement period, and the payment amount are all negotiated.

Earnout periods most commonly run 12 to 36 months. Longer periods mean more time for things to go wrong, and more time during which you have no control over the business. The metric matters too. Gross revenue is harder for a buyer to manipulate than EBITDA, because EBITDA can be reduced by new expenses the buyer chooses to add after closing.

The risks sellers routinely underestimate

Here is the core problem with earnouts: after closing, you no longer control the business. The buyer does. If they change the pricing structure, stop selling a product line, restructure the sales team, or shift the business toward a different customer segment, revenue may fall. And if revenue falls, you don’t collect.

Disputes over whether targets were hit are common. The calculation methodology needs to be defined precisely in the purchase agreement, down to the specific accounting treatment for every line item. Vague language that seemed reasonable during negotiation becomes a source of conflict when real money is on the line.

Some earnouts never pay out, not because the business failed, but because the buyer made decisions that changed the trajectory. An owner who expected a $500,000 earnout collects nothing and has limited legal recourse if the contract language permitted those decisions.

When earnouts can actually work

Earnouts are not always a bad deal. They can work well under specific conditions.

The most important factor is whether you stay involved after closing in a meaningful management role. If you’re running the business or staying closely involved in sales, you have direct influence over whether the targets get hit. The risk drops substantially compared to walking away on day one.

The metric also matters. Gross revenue is the most seller-friendly earnout metric because it’s transparent and hard for the buyer to game. EBITDA-based earnouts give the buyer more room to manage the outcome through expense decisions.

Finally, the buyer’s track record matters. A buyer who has acquired businesses before and consistently honored earnout payments is a very different situation from a first-time buyer or a private equity firm known for post-close restructuring.

What to do before you sign an earnout

Have your attorney review every line of the earnout terms before you sign the letter of intent. The earnout structure is often introduced in the LOI, and once you’re in an exclusivity period with one buyer, your leverage to renegotiate those terms is limited.

Define the metric precisely. Define what counts as revenue or EBITDA for purposes of the earnout calculation. Define what business decisions require your consent during the earnout period. Define the payment schedule and what happens if the buyer disputes the calculation.

An earnout that is poorly defined in the contract is a promise, not a payment.

Common questions owners ask

What's the difference between an earnout and a seller's note?

A seller's note is a fixed obligation. The buyer owes you the agreed amount regardless of how the business performs, similar to a loan. An earnout is contingent, you only get paid if the business hits specific targets. Seller's notes are more predictable because the payment doesn't depend on the buyer's future decisions. An earnout can pay more if the business does well, but it can also pay nothing if the buyer changes direction after closing.

Can I negotiate to limit my earnout exposure?

Yes. Several approaches reduce risk. Push to use gross revenue as the earnout metric instead of EBITDA or net profit, since revenue is harder for a buyer to manipulate. Negotiate a shorter earnout period, one year is better than three. Include protective covenants requiring the buyer to run the business in a way that gives you a fair chance to hit the targets. Have your attorney define the calculation methodology precisely in the purchase agreement. Every vague term in an earnout eventually becomes a dispute.

How common are earnout disputes?

More common than most sellers expect. Studies of mid-market transactions suggest that a meaningful portion of earnouts result in disputes, often because the contract language didn't define the calculation clearly enough or because the buyer made post-close decisions that affected performance. The risk rises when EBITDA is the metric (easier to manage through expense decisions) and when the buyer has a history of post-close integration changes. Reference checks on the buyer before signing matter more than most sellers realize.
