Earnouts: Bridging a Price Gap Without Overpaying

Short answer: An earnout pays the seller part of the price later, and only if the business earns it. Used well, it converts an argument about the future into a wager both sides can sign: the seller who believes the forecast gets paid when it comes true, and the buyer stops paying today for growth that has not happened. Used badly, it is the most litigated instrument in small M&A. And on an SBA-financed complete purchase it is barred outright, which most buyers learn at underwriting instead of before the LOI. The craft is knowing when an earnout is the right bridge, how to build one that cannot be gamed, and what to use when the rules take it off the table.

What the earnout is actually for

Every stuck negotiation at this size has the same shape: the seller prices the business on what it is about to do, the buyer prices it on what it has done. The earnout resolves that gap honestly. Part of the price, commonly 10 to 30 percent of total consideration, is deferred and tied to defined performance. If the seller's story is true, they collect. If it is not, the buyer did not pay for it. That honesty is why an earnout is also a diagnostic: a seller who refuses any performance linkage is telling you something about their own forecast.

Restraint matters, though. Even among large private deals, earnouts appear in fewer than one in five and have been declining, so the instrument is a targeted answer to a specific value gap, usually one tied to a named risk like customer concentration or a hot growth claim, not a default term in every offer.

Building one that does not end in court

Earnout disputes are almost never about bad faith. They are about ambiguity, and they are predictable at signing. The first rule is to measure what the seller can influence and the parties cannot argue about. Revenue and gross-profit targets are cleaner and less litigated than EBITDA targets, because EBITDA invites fights over allocated overhead and the buyer's post-close investments. Retention-based earnouts, keyed to named customers staying, are cleaner still when concentration is the risk being bridged.

The second rule is to write the mechanics like you expect the dispute: define the metric to the accounting policy, set the measurement periods and the cap, decide now what happens if the buyer sells or reorganizes the company mid-earnout, and name who calculates and how disagreements resolve. The third rule is to keep the operating covenant light but real: the seller needs assurance you will not starve the business to dodge the target, and you need freedom to run the company you just bought.

The SBA hard stop, and the mirror that is allowed

On an SBA complete change of ownership, seller earnouts are prohibited, full stop. Contingent future payment to the seller retains a seller interest in the business, and the change-of-ownership rules require it be struck from the agreement. What the SOP expressly permits is the mirror image: a buyer rebate, where the seller refunds part of the price if the business misses defined targets, applied first to pay down the loan. Same honesty about the forecast, opposite direction of payment. The related instrument is the forgivable seller note, where a slice of the seller note is forgiven if performance falls short, documented as a price reduction.

So the sequencing matters: decide the financing path first, then pick the bridge the path permits. A deal that genuinely cannot close without a true seller earnout is a deal that belongs on conventional debt or private credit, and knowing that before the LOI is Deal Structure work, not a closing-week discovery.
