Earn-Out

A deal structure in which part of an acquisition price is paid later, contingent on the acquired business hitting agreed performance targets. A bridge across a valuation gap, built out of deferred disagreement.

Buyer and seller could not agree what the business is worth, so they agreed to let the next two years decide. The disagreement did not go away. It moved into the contract, where it compounds.

The mechanics

An earn-out makes a portion of the purchase price conditional on post-completion performance, typically revenue, EBITDA or defined milestones measured over one to three years. The seller receives the deferred payment only if the targets are met; the definitions, measurement rules and governance rights are set out in the sale agreement.

Bridging a valuation gap, deferring a disagreement

Earn-outs exist because the seller believes a growth story the buyer will not pay for up front. As a preparation question for the deal decision, the structure cuts both ways. It reduces the buyer's risk of overpaying for projections, but it also constrains the buyer's freedom after completion: integrating the business, changing its sales model or moving its people can all be argued to have damaged the earn-out, and sale agreements increasingly oblige the buyer to run the business in ways that protect it. An acquirer whose deal logic depends on rapid integration and whose price structure depends on an earn-out has signed two contradictory plans.

Disputes the structure invites

  • Targets measured on metrics the seller no longer controls once the buyer owns the P&L.
  • Accounting policy changes after completion that move the measured number without moving the business.
  • Integration frozen for the earn-out period, deferring the synergies the price assumed.
  • Founders managing to the earn-out formula rather than to the long-term health of the business.

The earn-out defers the disagreement. It does not resolve it.
