Earn-Out
An earn-out is a portion of the purchase price that a buyer pays only if the acquired business hits agreed performance targets after closing, most often revenue, gross profit, or EBITDA measured annually over one to three years. Earn-outs bridge a valuation gap when a buyer will not pay at closing for growth the seller is projecting, and they pay nothing at all if the target is missed.

How an earn-out is structured
An earn-out is seven decisions, and each one is a place the structure fails in practice: the metric, the measurement period, the payout curve, the cap, the payment timing, the buyer's right of setoff, and the mechanics for calculating and disputing the number.
Two of those carry more weight than sellers expect. Setoff lets a buyer apply an unresolved indemnity claim against a payment the seller has already earned. And an earn-out that is not secured is an unsecured claim against a buyer whose balance sheet the seller has no visibility into once the closing is done.
- Metric: revenue, gross profit, EBITDA, or a defined milestone — with the accounting policies used to compute it fixed in the agreement, not left to the buyer's post-close judgment.
- Period: one to three annual measurement periods, occasionally with a cumulative catch-up so a strong second year can recover a missed first year.
- Curve: a cliff (nothing below target, full payment at or above it), a linear band between a floor and a ceiling, or stepped tiers.
- Cap: a stated maximum, and whether unearned amounts roll forward.
- Payment timing: typically 30 to 90 days after the period-end financials are finalized.
- Setoff: whether the buyer may reduce an earn-out payment by the amount of an unresolved indemnity claim.
- Dispute resolution: an independent accounting firm acting as expert rather than arbitrator, with a defined scope and cost allocation.
A worked example
A business sells for $8,000,000 of total consideration against trailing EBITDA of $1,600,000 at closing — 5.0x — split into $6,500,000 cash at closing and up to $1,500,000 of earn-out across two annual periods, $750,000 per period.
The curve for each period: nothing is paid if EBITDA for the period is below $1,400,000; the full $750,000 is paid at $1,800,000 or above; between those two figures the payment scales linearly.
Year one EBITDA comes in at $1,650,000. The payment is 750,000 × (1,650,000 − 1,400,000) ÷ (1,800,000 − 1,400,000) = 750,000 × 250,000 ÷ 400,000 = 750,000 × 0.625 = $468,750.
Year two EBITDA is $1,850,000, above the ceiling, so the payment is the full $750,000.
Total earn-out paid: 468,750 + 750,000 = $1,218,750 of the $1,500,000 available. Total consideration actually received: 6,500,000 + 1,218,750 = $7,718,750 against a headline price of $8,000,000 — 96.5% of the number both parties quoted.
That is a good outcome. The instructive version is the year where EBITDA lands at $1,395,000, five thousand dollars below the floor, and the payment is zero. A cliff of that shape converts a $5,000 accounting judgment — whether a bonus accrual belongs in the period, say — into a $750,000 dispute. Linear bands and cumulative catch-ups exist to defuse exactly that.
Choosing the metric: revenue, gross profit, or EBITDA
The further down the income statement the metric sits, the more the buyer controls it. That single sentence explains most earn-out negotiations.
Revenue is the seller's preferred metric because it is the hardest to manipulate and the easiest to verify. Its weakness is that a seller can hit a revenue target with unprofitable work, so buyers resist it unless margin is structurally stable.
EBITDA is the buyer's preferred metric and the most litigated. After closing, the buyer decides how much corporate overhead to allocate, whether to raise wages, whether to fund a sales hire that depresses this year's earnings, and how to account for integration costs. Every one of those is legitimate management judgment, and every one of them reduces the seller's payment. Where EBITDA is the metric, the agreement has to define it as a formula with named inclusions and exclusions rather than as 'EBITDA determined in accordance with the buyer's accounting policies'.
Gross profit is the usual compromise in lower-middle-market deals: harder to game than revenue, far less exposed to buyer discretion than EBITDA, and computable from data both sides can see.
In Main Street and lower-middle-market transactions, earn-outs typically represent 10% to 25% of total consideration over a one-to-three-year term. Above roughly a third of the price, the structure stops bridging a valuation gap and starts transferring the business's operating risk to a seller who no longer runs it.
The covenants that decide whether an earn-out ever pays
Sellers routinely assume the buyer carries a general obligation to try. Delaware, the governing law of choice for most US M&A, reads the implied covenant of good faith and fair dealing narrowly. In Winshall v. Viacom International (Del. 2013), the Delaware Supreme Court declined to use the implied covenant to require a buyer to take steps that would have increased the sellers' earn-out, reasoning that the covenant fills genuine gaps in a contract rather than supplying a protection the parties could have bargained for and did not.
The consequence is practical rather than philosophical: whatever a seller needs the buyer to do, or not do, has to be written into the agreement.
The covenants worth negotiating for are these: operate the acquired business in the ordinary course consistent with past practice; maintain separate books and records for the earn-out period so the metric is computable at all; no allocation of buyer corporate overhead, management fees, or acquisition costs into the metric; no reduction of sales headcount or marketing spend below a stated floor; no transfer of the acquired business's customers or product lines to an affiliate; a seller right to receive the supporting calculation and inspect the records behind it; and acceleration of the remaining earn-out if the buyer resells the business or terminates the seller without cause during the earn-out period.
Where the seller will not be running the business post-close, an earn-out is worth materially less than its face value. It is a bet on someone else's execution, measured by someone else's accounting.
Earn-out, seller note, escrow, and rollover equity
Four instruments defer part of the price, and they are not interchangeable.
An earn-out is contingent on future performance and can pay zero. The seller carries the risk of the business's results after closing.
A seller note is debt: a fixed principal and interest schedule the buyer owes unconditionally, subject only to setoff rights and to whatever subordination the senior lender demands. The seller's risk is the buyer's credit, not the business's performance. Trading an earn-out for a seller note of the same face value moves the seller from performance risk to credit risk, which is almost always the better side of that trade.
An escrow or holdback is money the seller has already earned, held by a third party against indemnification claims for a defined survival period and released automatically if no claim is made. The seller's risk is the accuracy of their own representations.
Rollover equity is the seller reinvesting: keeping a minority stake in the acquired company and getting paid on the next sale. The seller's risk is the buyer's entire plan, over a longer horizon, with less control than any of the above and no scheduled liquidity.
Ranked by seller risk, from lowest: escrow, seller note, earn-out, rollover.
Tax treatment
Earn-out taxation is a structuring question with real dollars in it. What follows is the general US federal framework; how it applies to any particular earn-out turns on that deal's own terms, and it belongs in front of a transaction tax advisor before the letter of intent is signed rather than after.
Earn-out payments generally fall under the installment sale rules of Internal Revenue Code section 453, so gain is recognized as payments are received rather than entirely at closing, unless the seller affirmatively elects out. Contingent payments with a stated maximum selling price and a fixed period have their own basis-recovery mechanics under the section 453 regulations, which is one reason a capped, fixed-term earn-out is administratively simpler than an open-ended one.
A portion of each deferred payment is recharacterized as interest under the imputed interest rules of sections 483 and 1274, and taxed as ordinary income rather than capital gain. A seller comparing an earn-out to cash at closing on a pre-tax basis is overstating the earn-out.
The trap that costs the most: an earn-out conditioned on the seller's continued employment can be recharacterized as compensation for services rather than purchase price — ordinary income to the seller, subject to payroll taxes, and deductible to the buyer. Payment mechanics that look like a bonus plan invite that treatment. Where the intent is purchase price, earn-outs are conventionally structured to be payable to the selling shareholders in proportion to their equity and to survive the seller's departure.
What is market, and when to refuse one
The ABA's Private Target Mergers and Acquisitions Deal Points Study is the standard reference for what is market in private US deals, and recent editions have reported earn-outs in a minority of surveyed transactions — on the order of one in four to one in three. Those surveyed deals skew considerably larger than Main Street transactions, so treat the figure as an upper bound on frequency rather than a benchmark to match.
Earn-outs make sense in a narrow set of cases: recent growth a buyer genuinely cannot underwrite, revenue concentrated in a contract that has not yet renewed, a product or location launched too recently to have a track record, or a seller staying on with real operational control.
They make less sense when the business is stable and the gap is simply that the parties disagree about the multiple. There the earn-out is not resolving uncertainty, it is postponing a negotiation — to a period when the seller has no leverage, no control, and limited visibility into the numbers that decide the payment. A slightly lower certain price is frequently worth more than a higher contingent one.
