An earnout is contingent purchase price paid to the seller after close, tied to post-close performance metrics (revenue, EBITDA, gross profit, customer retention). In 2026 lower-middle-market deals, 40-60% of stated earnout typically gets paid, not 100%, because the four common traps wipe out the rest: (1) accounting method changes buyers make post-close, (2) budget-timing games, (3) discretionary reinvestment that suppresses reported EBITDA, and (4) integration decisions that shift customers between reporting units.

What Is an Earnout and How Does It Work in 2026: The 4 Traps That Wipe Out 40-60% of Stated Value

An earnout is deferred contingent consideration in a business sale, a slice of the purchase price the seller earns only if the company hits agreed performance targets after closing. Buyers use earnouts to bridge a valuation gap, share post-close risk, and keep the founder accountable through the handover. Sellers accept earnouts because the alternative is often a lower all-cash price or no deal at all. Across the lower middle market (LMM), roughly 35 to 50 percent of private company deals carry some form of earnout, according to the IBBA Market Pulse reports for 2024 and 2025.

This is the focused answer. For the long-form deep dive, see earnouts explained, how they work and when they backfire, and the 2026 Earnout Benchmark Report.

What an Earnout Is in Plain English

In a typical LMM deal, the buyer pays a fixed amount at closing (cash plus rolled equity plus a seller note if any) and then promises additional payments over the next one to three years if the business performs to plan.

In a typical LMM deal, the buyer pays a fixed amount at closing (cash plus rolled equity plus a seller note if any) and then promises additional payments over the next one to three years if the business performs to plan. Those additional payments are the earnout. Legally the earnout sits inside the definitive purchase agreement (the SPA or APA) as a contingent obligation, not a guaranteed debt, which is why accountants record it at fair value and lawyers spend hours arguing over the math.

Closing-day cash is what the buyer is willing to pay for the business they can see today. The earnout is what they will pay for the business the seller says it will be tomorrow. Tomorrow has to actually arrive for the money to land.

Why Buyers Insist on Earnouts

Three reasons drive almost every earnout in the lower middle market. Bridge a valuation gap. The seller thinks the business is worth 6x EBITDA. The buyer underwrites at 4.5x because customer concentration is high or growth is unproven. Rather than walk away, both sides agree on 4.5x at close plus a 1.5x earnout over two years tied to revenue or EBITDA hitting the seller’s forecast. If the forecast was real.

Three reasons drive almost every earnout in the lower middle market.

Bridge a valuation gap. The seller thinks the business is worth 6x EBITDA. The buyer underwrites at 4.5x because customer concentration is high or growth is unproven. Rather than walk away, both sides agree on 4.5x at close plus a 1.5x earnout over two years tied to revenue or EBITDA hitting the seller’s forecast. If the forecast was real, the seller gets paid the full 6x. If it was puffery, the buyer protected itself.

Shift risk onto the party who controls it. Customer retention, key-employee retention, and the founder’s personal relationships all sit with the seller on day one. An earnout puts a price tag on those soft assets and only releases the money if they survive the transition.

Keep the founder engaged through transition. A founder who has 30 percent of their proceeds tied to a two-year earnout will answer the phone on a Saturday. A founder who got 100 percent cash at close will not. Buyers know this, and the structure works.

How an Earnout Is Structured

Earnouts in the LMM follow a recognizable template. Knowing the template is half of negotiating one. Size. The earnout is usually 15 to 30 percent of total consideration. Below 10 percent it is not worth the legal fees. Above 40 percent it starts to look like seller financing the buyer’s risk, which is a red flag in itself. Measurement period. Two years is the median, three years is common for.

Size. The earnout is usually 15 to 30 percent of total consideration. Below 10 percent it is not worth the legal fees. Above 40 percent it starts to look like seller financing the buyer’s risk, which is a red flag in itself.

Measurement period. Two years is the median, three years is common for higher-risk deals, one year happens but is rare because seasonality and integration noise distort a 12-month look. The IBBA Market Pulse Q4 2024 report shows the bulk of Main Street and LMM earnouts clustered at 24 months.

Metric. EBITDA is the most common metric in the LMM because it ties payment to profit, not vanity revenue. Revenue earnouts are easier to manipulate (the buyer can grow revenue and lose money to hit the trigger). Customer retention, gross profit, and unit volume are used in specific verticals: SaaS, distribution, professional services.

Payout curve. Two shapes dominate.

• Cliff: Hit the target and the full earnout pays. Miss it and zero pays. Cliffs favor the buyer because near-misses lose everything.
• Sliding scale: Each dollar of EBITDA above a floor pays a defined multiple, up to a cap. Sellers should push hard for sliding scale with a low floor so a 90 percent year still pays roughly 90 percent of the earnout.

Payment timing. Most earnouts pay annually at the end of each measurement year, audited or reviewed by an independent accountant. Some pay in a single lump at the end of the full period. Annual is friendlier to sellers because it locks in cash already earned even if year two goes sideways.

What Is an Earnout Worth, Realistically

The headline number on a term sheet and the cash that lands in the seller’s account are rarely the same. Industry data and our own deal review across the lower middle market suggest sellers collect roughly 40 to 60 percent of the stated earnout on average. Some hit 100 percent. A meaningful minority collect zero. The variance is driven by four things. How realistic the targets were at signing. Sellers.

Industry data and our own deal review across the lower middle market suggest sellers collect roughly 40 to 60 percent of the stated earnout on average. Some hit 100 percent. A meaningful minority collect zero. The variance is driven by four things.

1. How realistic the targets were at signing. Sellers who let the buyer set the bar at “stretch case” almost always miss.
2. How much control the seller kept post-close. A founder who stays as president for the earnout period and reports to the board has a fighting chance. A founder who is shoved into a consultant role on day 30 is usually finished.
3. How tightly the accounting is defined. “EBITDA” without a 3-page schedule of adjustments is a future lawsuit. “EBITDA per Exhibit C, calculated consistent with the audited financials for the trailing twelve months ended X” is enforceable.
4. Buyer integrity. Most institutional buyers pay what is owed. Some buyers, especially first-time strategics and undercapitalized PE, will look for any reason not to pay. Reference checks on the buyer matter as much as price.

What Sellers Risk in an Earnout

The core risk is straightforward: the seller no longer controls the business but is paid based on how the business performs. Specific traps repeat across deals. Buyer changes the playbook. The new owner cuts the marketing budget, raises prices, fires the head of sales, or shifts customers to a different brand. Revenue softens. The earnout misses. The seller had nothing to do with it. Allocation and shared services. The acquired.

Buyer changes the playbook. The new owner cuts the marketing budget, raises prices, fires the head of sales, or shifts customers to a different brand. Revenue softens. The earnout misses. The seller had nothing to do with it.

Allocation and shared services. The acquired company starts absorbing corporate overhead allocations from the parent. EBITDA drops on paper. The earnout misses.

Strategic decisions that hurt the metric. The buyer decides to invest in a new product line, depressing EBITDA in year one for a long-term payoff. The seller’s earnout, measured on year-one EBITDA, evaporates.

Force majeure. A recession, a key customer bankruptcy, a regulatory change. The IBBA Market Pulse covering 2020 deals showed a sharp jump in earnout disputes as COVID demand shocks crushed measurement periods set in 2019.

How Sellers Protect an Earnout

Smart sellers negotiate protective covenants into the SPA before signing. The standard package: Ordinary-course covenant. The buyer must operate the business in the ordinary course consistent with past practice during the earnout period. This blocks dramatic strategic pivots that would tank the metric. GAAP-plus accounting carve-outs. Define exactly which accounting methods apply, which overhead allocations are excluded, and which one-time items get added back. A 2-page accounting exhibit is cheap.

GAAP-plus accounting carve-outs. Define exactly which accounting methods apply, which overhead allocations are excluded, and which one-time items get added back. A 2-page accounting exhibit is cheap insurance.

No-shop / no-divert covenant. Prevents the buyer from moving customers or revenue to an affiliate to dodge the earnout.

Material adverse change (MAC) gross-up. If a defined external event happens (loss of a top-three customer, change in law, pandemic), the targets are adjusted or the earnout is accelerated.

Audit rights. The seller gets the right to inspect books and challenge the buyer’s earnout calculation. Without this, the buyer’s number is final.

Acceleration on change of control or termination. If the buyer flips the company or terminates the founder without cause, the remaining earnout is owed in full.

Dispute resolution. A named independent accountant resolves earnout calculation disputes. Faster and cheaper than litigation.

These protections are negotiated in the letter of intent and locked into the definitive agreement. A clean quality of earnings report before LOI also matters, because it establishes the EBITDA baseline both sides will measure against.

How Does an Earnout Get Paid Out

The mechanics in a normal deal: The measurement year ends (12 months after closing for an annual earnout). The buyer prepares an earnout statement, usually within 60 to 90 days, showing EBITDA, the payout calculation, and the amount owed. The seller has 30 to 60 days to review and object. Objections trigger the independent accountant clause. Once finalized, the buyer pays in cash within 30 days. Some deals allow the.

4. Once finalized, the buyer pays in cash within 30 days. Some deals allow the buyer to elect to pay in stock if the buyer is publicly traded.
5. Tax treatment for the seller is usually capital gain (installment method under IRC Section 453), but earnouts tied to continued employment can be recharacterized as ordinary compensation. A tax attorney must review the structure before signing.

Real Examples: Earnouts That Worked and Earnouts That Did Not

Worked. A founder sold a regional HVAC platform to a PE-backed consolidator at 5.5x trailing EBITDA, with a 1.5x sliding-scale earnout over two years tied to EBITDA growth of 15 percent annually. The founder stayed as president, the buyer left operations alone, and EBITDA grew 22 percent in year one and 18 percent in year two. The full earnout paid out at roughly 95 percent of the cap, landing the.

The founder stayed as president, the buyer left operations alone, and EBITDA grew 22 percent in year one and 18 percent in year two. The full earnout paid out at roughly 95 percent of the cap, landing the founder at an effective 6.95x multiple.

Did not work. A SaaS founder sold to a strategic at 4x ARR with a 1.5x earnout tied to net revenue retention staying above 110 percent. The buyer integrated the product into its own pricing tiers, raised prices on the acquired customer base by 30 percent, and NRR dropped to 96 percent. Earnout paid zero. The seller sued and settled for 18 cents on the dollar after two years of litigation. The ordinary-course covenant had not been tight enough to block the pricing change.

The pattern is consistent: earnouts pay when the buyer leaves the engine alone and the seller stays at the wheel.

When You Should Accept an Earnout and When You Should Not

Accept an earnout if: the buyer is institutional with a track record of paying earnouts in past deals, the targets are based on trailing actuals not stretch forecasts, you will keep operational control during the measurement period, and the SPA gives you the protective covenants above.

Accept an earnout if: the buyer is institutional with a track record of paying earnouts in past deals, the targets are based on trailing actuals not stretch forecasts, you will keep operational control during the measurement period, and the SPA gives you the protective covenants above.

Walk from an earnout if: it is more than 40 percent of total consideration, the metric is something you cannot influence post-close, the buyer refuses ordinary-course covenants, or the buyer has a reputation for litigating earnout payments. In those cases, push for a lower all-cash price plus a seller note instead. A 7 percent seller note that you actually collect beats a 1.5x earnout you will never see.

Frequently Asked Questions About Earnouts

What is an earnout in a business sale?

An earnout is a portion of the purchase price that the buyer agrees to pay after closing if the business hits specific performance targets, usually EBITDA or revenue, over a defined measurement period of one to three years. It is contingent, not guaranteed.

How does an earnout work in practice?

The buyer pays a fixed amount at closing plus a contingent earnout. After each measurement year, the buyer calculates EBITDA per the agreed accounting method, applies the payout formula, and pays the seller the amount earned. Annual payments are the norm in the LMM.

What percentage of deals include an earnout?

Roughly 35 to 50 percent of lower middle market deals carry an earnout, based on the IBBA Market Pulse reports for 2024 and 2025. The percentage is higher in deals over $5M in enterprise value and in industries with customer concentration or growth uncertainty.

How much of a stated earnout do sellers actually collect?

Industry data and our own deal review suggest sellers collect roughly 40 to 60 percent of the stated earnout on average. The full earnout pays out in deals where targets were realistic, the founder stayed engaged, and the buyer respected the operating playbook. Zero payouts happen when targets were aspirational or the buyer integrated aggressively.

How long do earnouts last?

Two years is the median in the lower middle market. Three years is common in deals with higher post-close risk or larger earnout amounts. One-year earnouts exist but are rare because a single year of results is too easily distorted by seasonality and integration noise.

EBITDA or revenue: which metric is better for the seller?

EBITDA aligns the seller’s payout with profitability, which is what the buyer ultimately cares about. Revenue earnouts are easier to game (the buyer can grow revenue while destroying margin to avoid paying). If you accept a revenue earnout, insist on a minimum gross margin floor as a tripwire.

What is the difference between an earnout and a seller note?

A seller note is a fixed debt obligation: the buyer owes the money on a schedule regardless of business performance. An earnout is contingent: the buyer only owes the money if targets are hit. Seller notes are senior to earnouts in collection and far safer for the seller. See our seller financing guide.

Can earnouts be negotiated after the LOI?

Yes but the heavy lifting belongs in the LOI. The LOI sets size, metric, period, and high-level payout curve. The definitive agreement adds protective covenants and accounting detail. Trying to renegotiate the headline economics during definitive drafting almost always fails because the buyer holds the upper hand at that stage.

Are earnouts taxed as capital gain or ordinary income?

Earnouts are usually taxed as capital gain under the IRC Section 453 installment method. Earnouts contingent on the seller’s continued employment can be recharacterized by the IRS as ordinary compensation, which carries a higher tax rate and payroll tax. The structure must be reviewed by a tax attorney before signing.

What happens to my earnout if the buyer sells the company?

If the SPA includes an acceleration-on-change-of-control clause, the remaining earnout becomes immediately due and payable in cash at the new transaction. Without that clause, your earnout depends on the new owner honoring the original agreement, which is a meaningfully worse position. Acceleration clauses are standard market practice and should be in every earnout.

The Bottom Line on Earnouts

An earnout is a useful tool when it bridges a real valuation gap between two reasonable parties. It is a trap when it is used to make a thin deal look fat or to give the buyer free optionality on payments they never intended to make. The structure works when the metric is something you can influence, the targets are anchored to trailing actuals, the SPA includes ordinary-course covenants and.

FAQ

Can I negotiate the earnout formula?

Yes. This is critical. Don’t accept vague metrics. Insist on specific definitions: Is retention measured by customer count, revenue, or both? How is churn calculated if you sell a division? Push back on overly aggressive targets. Your retention baseline before acquisition should be the starting point, not an inflated goal. Include dispute resolution language for disagreements.
