When a buyer and seller cannot agree on price, earn-outs often appear as the solution. In theory, they bridge the valuation gap: the seller gets a higher total price if the business performs as expected, and the buyer limits downside risk by tying part of the payment to actual results. In practice, earn-outs are more complicated and more dangerous for sellers than they appear on the surface. Here is what you need to understand before you agree to one.

What Is an Earn-Out?

An earn-out is a portion of the purchase price that is not paid at closing. Instead, it is paid out over a defined period, typically one to three years, contingent on the business hitting agreed-upon performance targets after the sale. The buyer takes ownership at closing and pays the base purchase price. The earn-out portion is held back and released only if the targets are met.

Example: A buyer offers .5 million for a business, but the seller believes it is worth million based on growth projections. The two parties agree to .5 million at closing plus up to 00,000 in earn-out payments over two years, tied to the business hitting 00,000 in annual revenue each year.

If the business hits those numbers, the seller collects the full million total. If it does not, the seller walks away with .5 million and no additional payment.

When Are Earn-Outs Used?

Earn-outs typically show up in three scenarios:

Valuation disagreement. The buyer and seller have genuinely different views on what the business is worth. The earn-out lets both sides bet on their own projections without deadlocking.

Uncertain future revenue. If a significant portion of the business’s value comes from contracts not yet signed, products not yet launched, or customer relationships that depend on the seller staying involved, a buyer will want future performance to validate the price.

Seller price maximization. Some sellers push for earn-outs because they believe the business will outperform and want upside participation after closing. This is the most optimistic version and is also where sellers often get disappointed.

How Earn-Out Targets Are Structured

The specific metric used as the earn-out target matters enormously. Common structures include:

Revenue Targets

Simple and easy to measure. The business must hit a gross revenue threshold each year. Sellers generally prefer revenue targets because they are harder for a buyer to manipulate. Buyers push back because revenue can be high while profits are low.

EBITDA Targets

Earnings before interest, taxes, depreciation, and amortization. More closely tied to actual profitability. The problem: EBITDA is easier to manipulate. A buyer who controls operations post-close can increase expenses, reallocate overhead, or change accounting policies in ways that suppress EBITDA and reduce earn-out payments.

Customer Retention or Milestone Targets

Sometimes used when the business’s value is concentrated in specific relationships or contracts. For example: retaining a named client, completing a product launch, or hitting a subscriber count. These can work well when the milestone is specific, binary, and verifiable.

The Real Risks for Sellers

Most earn-out disputes end badly for sellers. Here is why:

The buyer controls the business. Once you sell and hand over operations, you have limited ability to influence whether earn-out targets are hit. The buyer can choose to invest heavily in growth, or they can cut costs aggressively, focus resources on other priorities, or simply let the business stagnate. Unless your earn-out agreement includes operating covenants that restrict these behaviors, you are largely at the buyer’s mercy.

Accounting manipulation is common. Especially with EBITDA-based earn-outs, buyers who also control the books have many levers available. Management fees charged to the entity, allocation of overhead from a parent company, or changes in depreciation policy can all reduce the reported metric without changing the underlying business performance.

Legal disputes are expensive and slow. A significant number of earn-out agreements end in litigation or arbitration. The legal costs alone can eat up a substantial portion of the disputed amount, and resolution can take years.

How to Protect Yourself as a Seller

If an earn-out is unavoidable, negotiate hard on these protections:

Use narrow, objective metrics. Revenue is better than EBITDA. Specific customer contracts or milestones are better still. The harder a metric is to manipulate, the safer it is for you.

Keep the earn-out period short. One to two years maximum. The longer the period, the more can go wrong and the less leverage you have.

Include operating covenants. The buyer should be contractually required to operate the business in ordinary course, maintain adequate staffing and marketing spend, and avoid actions specifically designed to suppress the earn-out metric.

Demand audit rights. You need the contractual right to audit the financial records used to calculate your earn-out. Without this, you have no way to verify the numbers are accurate.

Negotiate strong reps and warranties. Solid representations and warranties from the buyer about the business’s operations post-close provide a legal foundation if disputes arise.

The Honest Take

Earn-outs favor buyers in the vast majority of cases. Sellers who accept large earn-out components in lieu of upfront cash often collect less than they expected, go through a contentious dispute process, and end up wishing they had taken a lower all-cash offer at closing.

The best strategy as a seller: push for maximum cash at closing and minimize the earn-out component. If an earn-out is necessary to close the deal, treat it as a bonus rather than a core part of your retirement plan. Anything you actually receive beyond the base price is upside. Structure your life around the guaranteed number, not the projected one.
