Earn-out

An earn-out is a portion of the purchase price paid only if the business hits agreed targets after closing. It is used to bridge disagreement about what a business is worth: the seller believes the earnings will continue, the buyer is not certain, and the earn-out lets the outcome decide.

Reviewed

Earn-outs are common where a business has a short track record, a recent spike in earnings, concentrated customers, or heavy owner involvement — anywhere a buyer’s doubt is specific rather than general.

Why they generate disputes

The seller no longer controls the business but their payment depends on how it performs. A buyer who changes pricing, cuts marketing, absorbs the business into a larger group, or reallocates overhead can reduce the measured result without any bad faith at all. Most earn-out disputes are about measurement, not honesty.

What a well-drafted earn-out fixes in advance

  • The exact metric — revenue is harder to manipulate than profit, and easier to verify
  • The measurement period, and who prepares the statements
  • What the buyer may and may not change during the period
  • The seller’s access to records to verify the calculation
  • How a dispute is resolved, and by whom
