Earn-out structure

Link a defined part of consideration to measurable post-completion performance while controlling calculation, conduct, reporting, payment and dispute risk.

Quick answer

An earn-out is contingent purchase consideration payable after completion if specified performance conditions are met. The agreement defines the metric, baseline or threshold, rate, period, cap, accounting rules, business-conduct obligations, information access, calculation statements, objections and settlement. Earn-outs can bridge valuation expectations, while creating exposure to post-completion decisions and measurement disputes.

Use the worked example

Meaning and transaction use

An SEC-filed asset purchase agreement provides annual earn-out payments as stated percentages of post-completion revenue and identifies the measurement periods and payment treatment. [S1]

A separate SEC-filed earn-out agreement addresses product identification, bundled-revenue allocation, quarterly calculation statements and annual payment timing. [S2]

Proposed control method: define every input and permitted adjustment, model scenarios, assign operating covenants and reporting responsibilities, and retain an auditable bridge from source systems to each earn-out statement.

Worked example

Illustrative revenue earn-out only. Assume eligible revenue of 20.0 million, a 15.0 million threshold, a 10% rate on excess revenue and a 1.0 million cap. Ignore taxes, currency and prior-period carry-forward.

Eligible revenueGiven20.0m
Revenue above threshold20.0 - 15.05.0m
Uncapped payment5.0 x 10%0.5m
Contractual capGiven1.0m
Illustrative earn-out paymentMinimum of 0.5 and 1.00.5m

The illustrative payment is 0.5 million because the calculated amount is below the cap. The executed agreement determines eligible revenue and all adjustments.

Proposed transaction review process

Allocate post-closing control

Set business-conduct obligations, information rights, reporting, audit access and decision boundaries.

Calculate and resolve

Prepare statements from controlled data, manage objections and settle under the agreed timetable.

Evidence checklist

Common errors to check

  • Using an undefined metric or changing accounting policies during the period.
  • Ignoring how integration or product bundling changes measurement.
  • Setting a cap without testing realistic performance scenarios.
  • Leaving information rights and dispute deadlines unclear.

Model the earn-out

Bring the valuation cases, operating forecast and proposed contingent terms to an earn-out review. Test the metric, control rights, reporting path and dispute mechanics across realistic scenarios.
