Earn-Out

An earn-out is a structure where part of the purchase price is paid only if the acquired company hits defined performance targets after closing.

Plain definition

What it means.

An earn-out is a deferred portion of purchase price contingent on post-closing performance. The seller receives a portion at closing and earns the remainder over a defined measurement period if the business hits the agreed targets.

Earn-outs commonly tie to revenue, EBITDA, gross margin, customer retention, or product milestones. The measurement period typically runs one to three years. The structure exists to bridge valuation gaps between buyer and seller, especially when the seller is more confident in the trajectory than the buyer is willing to pay for upfront.

An earn-out is the part of the deal that pays the seller for what happens after they no longer fully control the outcome.

What goes wrong

The failure pattern this term exists to prevent.

The metric the buyer can shape

The earn-out is tied to EBITDA. The buyer integrates the company, allocates corporate overhead, recognizes revenue under different rules, and the EBITDA number stops resembling the standalone business. The earn-out target was reasonable on the standalone forecast and unreachable inside the buyer's reporting structure.

The control that disappeared at closing

The seller stays on through the earn-out period. The seller no longer makes the hiring decisions, the pricing decisions, or the investment decisions. The seller is now responsible for hitting the targets but does not run the levers that drive them.

The cap that clipped the upside

The earn-out has a cap at 110 percent of the base target. The business outperforms by 30 percent. The seller hits the cap and stops being paid for the rest of the over-performance. The buyer keeps the remainder. The cap was a small line in the term sheet.

The dispute that dragged for years

The earn-out target is a number the parties calculate differently. The seller calculates one number. The buyer calculates another. The contract requires arbitration. By the time it lands, the seller has already moved on to other things.

Founder questions

The questions people actually ask.

How is an earn-out structured? An earn-out splits purchase price into a closing payment and a contingent payment tied to defined post-closing performance. The contingent portion is measured against revenue, EBITDA, customer retention, or specific milestones over a measurement period of typically one to three years.

Why do buyers and sellers use earn-outs? Earn-outs bridge valuation gaps. The seller is more confident in the trajectory. The buyer is unwilling to pay for that confidence upfront. The earn-out shifts a portion of the price to be paid only if the trajectory plays out, sharing risk between the two sides.

What are the most common earn-out disputes? Disputes typically arise over how the metric is calculated post-closing, how integration costs are allocated, whether the buyer has run the business to hit or to miss the target, and whether the seller had the authority needed to pursue the targets. Most earn-out disputes resolve in arbitration or settlement.

How can a seller protect an earn-out at the negotiation stage? Define the metric narrowly and based on the standalone business. Carve out integration effects from the calculation. Preserve operating authority for the seller during the measurement period. Avoid metrics the buyer can change unilaterally. Include a defined dispute resolution path with reasonable timing.

Bigger picture

Where this fits in the structure.

Related structure Escrow Holdback

Earn-out is purchase price paid forward if performance hits. Escrow is purchase price held back if claims arrive. The seller often carries both at closing.

Liquidation preference shapes what a closing payment actually pays. Earn-out shapes how much closing payment there is to begin with.

The operating-side framing of when the offer math, including the earn-out, does not actually work for the seller.

If an earn-out is being negotiated and the metric, the cap, or the post-closing control structure is on the table, that is a different conversation.
