How Earnout Confirmation Works
The process generally begins when the relevant measurement period ends. The buyer or designated party prepares a calculation using the accounting records and other evidence specified in the transaction agreement. The seller may then review the calculation and supporting information before accepting the result or raising a formal dispute.
- Measurement period closes: The contractual period for assessing performance ends.
- Performance data is compiled: Financial and operational records are collected according to the agreement.
- Earnout calculation is prepared: Actual performance is compared with the agreed targets and calculation methodology.
- Supporting evidence is reviewed: Relevant statements, reports, schedules, and source records are examined.
- Amount is confirmed: The parties approve the payable amount or follow the contractual dispute process.
Key Information Used for Confirmation
An Earnout Confirmation should be supported by evidence that directly corresponds to the contractual performance conditions. Financial measures may require income statements, revenue schedules, general ledger records, customer reports, or other accounting data.
Non-financial conditions may require customer records, product development documentation, regulatory approvals, signed contracts, or operational reports. The appropriate evidence depends on the earnout's design and the definitions established in the purchase agreement.
For example, if an agreement provides an additional $2 million when revenue reaches $10 million during a specified period, the confirmation should demonstrate both the qualifying revenue figure and the calculation used to determine the resulting payment.
Earnout Confirmation and Transaction Controls
Clear documentation is important because earnout calculations can affect the final economics of an acquisition. The confirmation should show how contractual definitions were applied, which accounting policies were used, and how adjustments or exceptional transactions were treated.
Finance teams may establish review procedures similar to other transaction-documentation workflows. A Receipt Confirmation verifies that goods or services have been received, while an Earnout Confirmation verifies that contractual performance requirements have been met for additional acquisition consideration.
Maintaining source records and calculation schedules also creates a clear audit trail for management, accounting teams, external advisers, and other authorized reviewers.
Earnout Confirmation vs Other Confirmations
An Earnout Confirmation has a different purpose from an Order Confirmation, which generally verifies the details of an order between a buyer and seller. An earnout confirmation instead relates to post-transaction performance and contingent purchase consideration.
Similarly, a Delivery Confirmation generally establishes that goods or services have been delivered or received according to an underlying transaction. Earnout confirmation evaluates whether defined acquisition-performance conditions have been achieved and whether an additional payment should be recognized or made.
These distinctions matter because each confirmation supports a different financial or operational event and relies on different underlying evidence.
Worked Example
Suppose a buyer acquires a business and agrees to pay a base purchase price plus an earnout of up to $3 million. The agreement states that $1 million is payable when annual revenue reaches $8 million, $2 million at $10 million, and $3 million at $12 million.
At the end of the measurement period, the financial records show qualifying revenue of $10 million. After applying the contractual definitions and reviewing the supporting records, the confirmed earnout is $2 million.
The confirmation should document the $10 million revenue result, the applicable threshold, any permitted adjustments, and the resulting $2 million payment obligation.
Best Practices for Earnout Confirmation
- Use the exact performance definitions and accounting rules stated in the acquisition agreement.
- Retain source records supporting every material component of the calculation.
- Document adjustments, exclusions, assumptions, and management judgments.
- Assign responsibility for preparing, reviewing, and approving the calculation.
- Observe contractual notice periods and dispute-resolution procedures.
- Maintain the final calculation and confirmation as part of the transaction records.
Consistent confirmation procedures help both parties understand how the contractual earnout provisions were applied and provide a defensible basis for the final payment determination and related financial reporting.
Summary
Earnout Confirmation verifies whether the performance conditions in an acquisition agreement have been achieved and establishes the additional consideration payable to the seller. It combines contractual definitions with financial or operational evidence, calculation schedules, and review procedures. A well-documented confirmation supports accurate payment determination, transaction records, and financial reporting.
