An earnout clause in a business sale is a provision that ties a portion of the purchase price to the future performance of the business after closing. When a buyer and seller disagree on what the business is worth today, an earnout bridges that gap by making some of the consideration contingent on what the business does tomorrow. In the lower middle market, earnouts show up fairly regularly, and it’s not unusual to receive an offer that includes one. What matters is whether this particular earnout is structured in a way that makes sense for your situation.
Most sellers who accept an earnout focus their attention on the headline number. If the deal is structured as $13.5M at close plus $1.5M in earnout over two years, the seller naturally tends to think of it as a $15M deal. But the earnout portion is not deferred payment. It is contingent payment. Those are different things. So, before you and your advisors negotiate the clause’s finer points, you need to address two questions. They’re not necessarily legal questions; they are business questions. And they can make all the difference in what happens next.
Question One: Is It Measurable?
The first question to ask about any earnout is whether the performance metric it is tied to can be measured clearly, consistently, and without ambiguity. This seems like it should be straightforward, but it’s where a significant number of earnout disputes begin.
Revenue is generally the cleaner metric. A dollar of revenue is a dollar of revenue. EBITDA (earnings before interest, taxes, depreciation, and amortization) is a more complex target because it is affected by decisions the buyer makes after closing: how overhead gets allocated, what expenses get charged to the business, how integration costs are treated. If your earnout is tied to an EBITDA target, you need a clear, written definition of exactly how that figure will be calculated, who calculates it, and what accounting standards apply. Without that definition locked down, the same business performance can produce two very different numbers, depending on who does the math.
The same logic applies to other metrics. Gross profit, customer retention rates, new contract signings, and project completions can all serve as earnout triggers. Each one carries its own measurement questions. Who tracks it? What counts and what does not? What happens if the buyer changes the product mix, the pricing structure, or the customer segmentation after closing in ways that affect the number?
A well-structured earnout clause specifies the metric, the measurement methodology, the accounting standards to be applied, and a process for resolving disputes about the calculation. Before you sign, you and your M&A advisor should be able to read the earnout clause and answer, without any guesswork, exactly how the payout will be calculated at the end of each measurement period. If the answer requires interpretation, the clause needs more specificity.
Question Two: Is It Achievable?
The second question can be harder to answer, but it’s just as important, because even if the metric is perfectly measurable, the earnout only pays if the business hits the target. So the real question is: after closing, who controls the decisions that determine whether you hit it?
When you sell your business, operational control transfers to the buyer. They set the budget. They make hiring decisions. They determine pricing strategy. They decide how aggressively to pursue new customers and which existing customers to prioritize. They choose whether and how to integrate your operation into their existing structure. All of those decisions affect the performance metrics your earnout is tied to.
If you plan to stay on after closing, you may feel confident that you can still drive the results. And you may be right. But your authority to make the decisions that drive those results is not the same as it was when you owned the business. The buyer is under no obligation to run the company the way you would run it. In the majority of deals, the buyer retains broad discretion over the operational decisions that determine whether the seller gets paid.
This is not a reason to reject every earnout, but it is a reason to be specific about what the buyer is and is not committing to. The achievability question requires you to think through a realistic scenario: given what you know about this buyer, their integration plans, and their priorities, is there a credible path to hitting the target under their management? If the answer depends on the buyer making choices that serve your earnout rather than their broader business interests, you should weigh that very carefully.
Your M&A advisor can help you pressure-test this. A buyer who is serious about the earnout being achievable should be willing to have a direct conversation about what post-closing operational decisions could affect the metric and how those decisions will be made. That conversation, and what the buyer is willing to commit to in writing, tells you a great deal about the realistic value of the earnout on the table.
How the Two Questions Work Together
Measurability and achievability are related but distinct. An earnout can be perfectly measurable and still be very difficult to achieve if the buyer controls the levers. It can be tied to a metric you are confident you can hit, but if the measurement methodology is vague, the payout becomes a negotiation rather than a calculation.
The strongest earnout structure for a seller is one where both questions have clear answers: the metric is defined with enough precision that there is no room for dispute about the number, and the post-closing operating environment gives you a realistic path to hitting it. When both conditions are present, an earnout can be a legitimate way to capture value that a buyer is not yet willing to pay upfront. When one or both conditions are absent, the earnout carries much more risk.
This is also why the earnout conversation belongs in the advisory stage, not just the legal drafting stage. Your transaction attorney will handle the clause language. But before you get there, the business question is whether the structure makes sense for your situation. If you are confident in the business’s trajectory and the buyer’s intentions, an earnout may be reasonable. If you have doubts about either, a higher upfront price at a lower headline number may serve you better than contingent consideration that depends on decisions you will no longer control. Understanding how different deal structures compare is part of making that judgment well.
What to Bring to Your Advisor Conversation
If you have an offer in hand that includes an earnout, come to the advisory conversation prepared to answer two sets of questions.
On measurability: What is the specific metric? How is it defined in the offer? Who calculates it, and under what accounting standards? What happens if you and the buyer disagree on the number?
On achievability: What operational decisions post-closing will most directly affect the metric? Who makes those decisions after closing? What has the buyer said, explicitly or implicitly, about how they intend to run the business? Are you staying on, and if so, in what capacity and with what authority?
You and your M&A advisor should start working through these questions together before legal drafting begins. The clause language matters. But the business logic underneath it is foundational to the conversation. If you are evaluating an offer and want a second set of eyes on the structure, a conversation with our team is a reasonable next step. There is no obligation, and you will leave with a clearer picture of what is on the table.
The goal is to understand exactly what you are agreeing to, and to make sure the structure gives you a legitimate opportunity to earn what the offer implies. Two questions get you most of the way there: Is it measurable? Is it achievable? If you can answer both with confidence, you are in a much stronger position to decide what to do next.
Frequently Asked Questions
An earnout clause is a provision in a business sale agreement that ties a portion of the purchase price to the future performance of the business after closing. If the business hits agreed-upon targets during the earnout period, the seller receives additional payment beyond the amount paid at closing. Earnouts are common in middle-market transactions when a buyer and seller have different views on what the business is currently worth.
In a typical structure, the buyer pays a portion of the agreed price at closing and holds back a defined amount, payable over one to three years if the business meets specific performance targets. The targets are usually tied to revenue, EBITDA, or another agreed metric. The seller often stays involved in the business during the earnout period, though the degree of operational authority varies significantly by deal.
Revenue and EBITDA are the most common earnout metrics in private company transactions. Revenue is generally simpler to measure and less subject to accounting interpretation. EBITDA is more complex because it can be affected by post-closing decisions the buyer makes about overhead allocation, integration costs, and expense treatment. Other metrics, such as gross profit, customer retention, or contract milestones, appear in deals where they more directly reflect the value the seller is being asked to deliver.
Earnout disputes are among the more frequent sources of post-closing litigation in private M&A transactions. Disputes typically center on how the metric is calculated, whether the buyer honored any operating commitments made during negotiation, and whether specific post-closing decisions were made in good faith. It’s also important to consider how much trust was built during the sale. This is difficult to measure, but your advisor can help ascertain it by running a process. Examining trustworthiness throughout the sale process, clearly defining metrics, and including well-drafted measurement provisions reduce the likelihood of disputes, but they do not eliminate the risk entirely.
Ask the buyer directly how they intend to run the business during the earnout period, what integration plans they have, and what decisions they anticipate making that could affect the performance metric. Ask whether they are willing to commit in writing to any operating standards during the earnout period. Their willingness to have that conversation, and what they are prepared to put in the agreement, tells you a great deal about how seriously they view the earnout as an obligation rather than an option.
Yes, and in some situations that is the better outcome for the seller. An earnout converts a valuation disagreement today into a performance question tomorrow, under the buyer’s management. If you are confident in the business’s trajectory and concerned about the buyer’s post-closing intentions, negotiating for more cash at close with a reduced valuation may provide more certain value than accepting contingent consideration tied to targets you no longer fully control. This tradeoff is worth working through carefully with your M&A advisor before you respond to any offer that includes an earnout.
