A seller signs his deal on a Thursday. The headline number is good, better than he expected, and by the weekend he has told his wife, his accountant, and two friends what the company “sold for.” That number becomes the story of his career. It is also, very often, a number he will never fully see.
Because somewhere in the structure of that deal, a large slice of the price was not paid at closing. It was promised, conditionally, depending on what the business does over the next two or three years. That slice is the earnout, and it is the single most misunderstood part of an M&A transaction for first-time sellers. People skim it during negotiation, when energy is focused on the big multiple and the lawyers are arguing about warranties. Then they read it very carefully two years later, when the money has not arrived and they finally want to understand why.
Let us read it carefully now instead, while it can still be changed.
1. What an Earnout Really Is, and Why the Buyer Loves It
An earnout is part of the purchase price that the buyer agrees to pay later, but only if the business hits agreed targets after the deal closes. Maybe forty percent of the total is paid upfront and the rest is spread over two or three years, released in pieces as the company delivers certain revenue or profit numbers.
From the buyer’s side this is a beautiful instrument, and you should understand why, because his reasons tell you exactly where his worries are. An earnout shifts risk from him onto you. If he is nervous that your projections are optimistic, that your clients might leave when you do, that the business leans too heavily on you personally, he does not have to argue about it. He simply moves more of the price into the earnout and lets the future settle the question. If the business performs, he pays. If it does not, he keeps the money and he was right to be cautious.
This is the part most sellers miss. The size of your earnout is a thermometer. A small earnout and a big upfront payment means the buyer believes in the business as it stands. A large earnout means he has doubts he is making you carry. The more dependent on you the company looks, or the more concentrated your clients, the more he will push into the conditional part. (This is one more reason to fix founder-dependency and client concentration long before you sell. We wrote about both, the one-client risk being the most obvious.)
2. The Trap in Plain Sight: Measured on What You No Longer Control
Here is the contradiction that sits at the heart of every earnout, and it is almost comic once you see it.
The day after closing, the buyer owns the company. He runs it. He decides where to invest, how to allocate costs, which clients to chase, whether to integrate your team into his, whether to change the pricing, whether to move your work onto his platform. You, meanwhile, are being paid based on numbers that all of those decisions affect. You are responsible for the result and you no longer hold the controls. Is like being told your bonus depends on the score of a match you are not allowed to play in.
Most of the time this is not even malicious. The buyer is simply running his business the way he thinks is best for the whole group, and your earnout is a small consideration inside a much bigger picture. He decides to push your biggest client toward a different service line that sits in another company he owns. Good for the group, bad for your earnout metric. He loads central management fees onto your P&L. Reasonable from his accounting view, fatal to your profit target. No villain required. The structure does the damage on its own.
So the central question of any earnout is not “what are the targets.” It is “who controls the levers that move the targets, and what stops them from being moved against me.” If the contract does not answer that, the targets are decoration.
3. Revenue or EBITDA: The Metric Is the Whole Game
What the earnout is measured on decides who has the advantage before a single number is calculated.
Revenue targets favor the seller. Revenue is hard for the buyer to manipulate, you can see it, it is what it is. If your earnout pays on revenue, the buyer cannot quietly shrink your number by allocating costs to your books. The trade is that revenue says nothing about profitability, so buyers resist pure revenue earnouts unless they are confident.
EBITDA or net profit targets favor the buyer, heavily, and this is where sellers get hurt. Profit is the bottom of the P&L, and the buyer controls almost everything between the top line and the bottom. Management fees, shared service charges, the cost of integrating your team, allocation of overhead, investment decisions, all of it lands above the profit line and all of it is in his hands. A seller who agrees to an EBITDA earnout without ironclad rules about how that EBITDA is calculated has effectively handed the buyer a dial he can turn down.
Gross profit, or a clearly defined contribution margin, often sits in a sensible middle. Whatever the metric, the definition matters more than the label. “EBITDA” means nothing until the contract specifies exactly which costs are in, which are out, which accounting policies apply, and whether the buyer can introduce new charges during the earnout period. I have seen deals where the whole fight, two years later, was about the meaning of one word that nobody pinned down at signing.
4. The Clauses That Decide Whether the Money Ever Arrives
This is the section to read twice. A handful of clauses, buried in the middle of the agreement, decide whether your earnout is real money or wishful thinking.
Operating covenants. The contract should commit the buyer to run the business in a consistent, normal way during the earnout period, and in good faith, and not to take deliberate actions that reduce the earnout. Without this, everything in section two is free for him to do.
Cost allocation rules. The agreement must say what costs can and cannot be charged to your business during the period. No new management fees, no dumping of group overhead, no intercompany charges invented after the fact. This single clause protects more earnout money than any other.
Set-off rights. Many contracts let the buyer deduct from your earnout any claims he has against you, for example a breach of warranty. So a dispute about something completely separate can swallow the earnout you actually earned. You want this limited and ring-fenced.
Acceleration on change of control. If the buyer sells the company again, or gets bought himself, during your earnout period, what happens to your money? Without an acceleration clause, your earnout can evaporate or fall into the hands of a new owner who never agreed to it. You want it to crystallize and pay out if control changes.
And then the measurement itself. Who calculates the numbers, on what timetable, what happens if you disagree, is there an independent expert to break a deadlock. The buyer’s finance team preparing the numbers with no review process is not a comfortable place to be when several hundred thousand euros depend on the result.
5. What Happens to the Earnout If You Leave
Most earnouts assume you stay and keep working, which ties the conditional money to your continued presence. This is the link between the earnout and the question of staying involved after the sale, something we treated on its own in Selling Your LSP Without Walking Away.
The danger is in the “what if.” What if you want to leave early. What if you fall ill. What if the buyer fires you, or makes your life unpleasant enough that you go. In a badly written deal, leaving for any reason can forfeit the unpaid earnout, which hands the buyer a quiet incentive to push you out before the money is due. The contract needs to separate the “good leaver” from the “bad leaver,” and to protect your earnout if you depart for reasons that are not your fault. Death, incapacity, termination without cause, these should not wipe out money the business actually earned.
This is also where the post-merger integration period gets dangerous, the same year-two fragility we described in The Post-Merger Integration Trap. The earnout window and the most unstable phase of the integration are usually the same two years. Plan for that overlap.
6. How to Negotiate One That Actually Pays Out
A few principles, learned mostly from watching them be ignored.
Push for the largest upfront payment you can, and treat everything beyond it as a maybe. The cleanest protection against a bad earnout is simply having less of your price exposed to it.
Prefer metrics you can see and the buyer cannot easily move. Revenue or gross profit over net EBITDA, wherever you can win that argument. Define every term, leave nothing to “we will work it out later,” because later is when you have lost all your leverage.
Insist on the operating and cost-allocation covenants from section four. These are not nice-to-have. They are the difference between an earnout and a story.
Ask for a floor, not only a cap. Buyers love to cap the upside. Fewer sellers think to negotiate a minimum, a guaranteed portion that pays regardless, in exchange for accepting the cap. And get the whole thing modeled by someone who does this for a living, with the bad scenarios run, not only the happy one the buyer’s spreadsheet shows you. The number that matters is the one you collect in the pessimistic case, becuase that is the case the structure is designed to produce when things drift.
7. The Honest Way to Think About the Number
An earnout is a bet on the future performance of a company you have just stopped controlling, with the odds written by the person on the other side of the table. Sometimes it pays in full and everybody is happy. Often it pays in part. Sometimes it pays nothing, and the seller spends the difference in legal fees trying to prove bad faith, which is hard to prove by design.
So when you tell people what your company “sold for,” be honest with yourself about which number you mean. The headline, or the part that was actually guaranteed. The mature way to enter a deal is to decide whether the upfront payment alone is a price you can live with. If the answer is yes, the earnout is upside and you can fight for it from a calm place. If the answer is no, and you are relying on the earnout to make the deal acceptable, you are not really selling on the terms you think you are. You are accepting the buyer’s doubts and hoping they were wrong.
Read it carefully now. The version of you two years from now will be grateful, or at least less angry.
