Earn-Out Structures Explained: How Indiana Sellers Actually Get Paid

Most sellers hear “earn-out” and think upside. Buyers hear “earn-out” and think risk transfer. That gap is where a lot of Indiana owners lose six figures.

In plain English, an earn out business sale means part of your price is not really purchase price on closing day. It is contingent consideration paid later if the business hits a target the buyer and seller negotiated in advance. Sometimes that target is fair. Often it is a polite way of saying the buyer does not want to pay your full number in cash.

That matters because Indiana still has real buyer depth. The latest Census QuickFacts county business counts available as of April 11, 2026 show Marion County with 24,248 employer establishments and 544,147 employees in 2023, Hamilton County with 10,446 and 165,539, Allen County with 9,696 and 190,285, and Elkhart County with 5,211 and 136,199. Good companies in those markets still attract multiple buyer types. They do not all attract the same structure, and earn-outs show up most often where transfer risk, financing limits, or customer concentration are still unresolved.

Debt cost is part of the story too. As of April 11, 2026, the Federal Reserve’s H.15 release showed bank prime at 6.75%. On standard SBA 7(a) acquisition debt above $350,000, SBA’s current ceiling remains prime plus 3.0%, or 9.75%. When debt is that expensive, buyers get more creative with structure. Some of that creativity is legitimate. Some of it is just delayed price reduction dressed up as alignment. If you need the broader sale sequence first, start with the 2026 ultimate seller guide.

At Midwest Business Brokers, we work in the $1 million to $10 million band, where the Double Lehman Scale keeps fee math transparent but where structure still decides the seller’s real outcome. On a $5.8 million deal, the Double Lehman fee is $316,000. If an earn-out shifts $900,000 of price out of closing and only half of it ever gets paid, the structure costs the seller $450,000. That is why serious sellers should spend less time admiring the headline number and more time asking how they actually get paid.

What an Earn-Out Is (And What Sellers Really Sign Up For)

An earn-out is contingent purchase price. It is not escrow. It is not a seller note. It is not a working-capital true-up. It is money the buyer only pays if the business hits a defined post-closing result.

That sounds harmless until you unpack who controls the result. In an all-cash closing, the seller’s main concern is whether the wire arrives and whether the purchase agreement exposes too much through reps, warranties, or working capital. In an earn-out structure, the seller is also betting on the buyer’s operating decisions, accounting choices, and willingness to report fairly after the seller no longer controls the company.

Take a representative $4.6 million Indiana deal. The buyer offers $3.7 million at close, a $250,000 escrow, a $200,000 seller note, and a $450,000 earn-out tied to the first two post-close years. The seller tells friends he sold for $4.6 million. What he actually did was close at $3.7 million, finance part of the purchase himself, leave part of the price exposed to indemnity claims, and put almost 10% of the consideration at risk on future performance.

What the seller is really signing up for

• Delayed payment. Part of the agreed value is no longer cash at closing.
• Performance risk. If the business misses the trigger, the seller does not get paid.
• Accounting risk. If the metric is EBITDA or margin, definitions suddenly matter more than the headline number.
• Control risk. The seller may be judged on a result the buyer materially influences after closing.

That is why the earn out agreement cannot be written like a summary paragraph in the LOI. It needs definitions, formulas, reporting deadlines, dispute mechanics, operating covenants, and examples. If the buyer says “we will work out the details later,” what they usually mean is “we want the leverage first and the precision later.”

If that math has not been pressure-tested against the real value of the business, get a Professional Valuation Assessment before you let a buyer define the contingent piece for you. Sellers get in trouble when they negotiate contingent price before they know the cash price the market would support.

When Earn-Outs Appear in Indiana Deals vs When They Should Not

No one publishes a clean statewide earn-out percentage for Indiana private company sales. The best available market studies are national. SRS Acquiom’s most recent private-target deal-terms study said one-third of private-target deals carried an earn-out. The ABA’s 2025 private-target deal points study, which skews larger and more traditional middle-market, showed 18% earn-out usage in that sample. Indiana lower-middle-market deals tend to land somewhere between those numbers, with a wide spread by industry, buyer type, and financing structure.

In practice, earn-outs show up in Indiana for five predictable reasons. First, the seller’s price expectation is above what the lender will finance. Second, the owner is still the chief rainmaker, operator, or relationship holder. Third, one or two customers still represent too much of revenue. Fourth, the business sits in a cyclical lane where one year’s performance can swing hard with local conditions. Fifth, the buyer is a first-time acquirer or searcher leaning heavily on debt and looking for a way to bridge the gap without writing more equity.

The county mix matters here. The latest QuickFacts employment change data available as of April 11, 2026 shows Elkhart County’s 2023 employment down 5.0% year over year, while Allen was up 2.2%, Marion 1.7%, and Hamilton 0.8%. Buyers know that. An Elkhart supplier tied to RV or transportation demand is more likely to get an EBITDA or named-customer earn-out than a well-diversified Hamilton County professional-services firm with recurring revenue and stable margins.

Earn-outs should appear far less often when the business already looks like a company rather than a job. If the target has documented reporting, management depth, diversified customers, and a buyer field with real competition, the seller should be asking why the buyer needs contingent price at all. A strong Indianapolis B2B services company with 88% recurring revenue and no customer over 10% should not accept a large earn-out just because one buyer says it is “market.”

Financing pressure is the other obvious trigger. If the structure only works because the buyer’s lender will not support full cash at close, read our breakdown of the SBA 7(a) acquisition loan. And remember that most of this leverage gets set earlier than sellers think. The letter of intent is where structure starts hardening, which is why sellers should understand how LOI structure terms lock in later risk before they sign exclusivity.

The Three Most Common Earn-Out Structures in 2026 M&A

In 2026 M&A, I see three earn-out structures repeatedly in $1 million to $10 million Indiana deals. They are not equally good. They are not equally dangerous. And they do not belong on the same types of businesses.

Revenue-based earn-outs are the cleanest when the seller’s real risk is account transfer, not profitability. Think a Fort Wayne janitorial platform buying a smaller route business or an Indianapolis HVAC buyer worried about the maintenance base renewing after the owner leaves. Revenue is easier to measure than EBITDA, but only if the agreement defines price changes, discounts, account movement, and returns.

EBITDA-based earn-outs are the most common and the most abused. They fit when the company is already marketed on EBITDA and the seller is being asked to stand behind sustainable profit, not just top-line volume. They also create the most fights because buyers can change staffing, marketing, ERP costs, corporate allocations, and reserve methodology. If the business is not already being thought about in true company-level earnings terms, this is often the wrong structure.

Customer-retention earn-outs work best when the buyer is buying a book of revenue and wants to know whether the named revenue stays. Accounting practices, route businesses, specialized B2B services, and companies with one or two outsized accounts fit here. These deals pay when the accounts transfer cleanly. They fail when the agreement measures customer count instead of revenue, or when the buyer changes service levels and then says attrition was the seller’s fault.

There is a simple rule I use with sellers. In this size range, the safest earn-out band is usually 10% to 20% of total consideration. When the contingent piece creeps past 25%, the seller is no longer using the earn-out as a bridge. The seller is financing the buyer’s uncertainty.

Performance Triggers: Revenue, EBITDA, Customer Retention, Other Metrics

The best trigger is the one most closely tied to the actual transfer risk in the deal. Sellers get hurt when the metric does not match the reason the buyer wanted contingent price in the first place.

Revenue can work, but only if the buyer cannot manipulate it easily

Revenue is attractive because everyone understands it and it is harder to fake than “adjusted EBITDA as determined by buyer.” If the real issue is whether customers stay, revenue from a named customer list is usually more seller-friendly than a broad company-wide profitability target. But revenue still gets distorted if the buyer changes pricing, bundles services differently, moves invoices to a sister company, or changes credit terms in a way that hurts collections.

When I accept a revenue trigger, I want named accounts, a defined measurement method, and explicit language on what happens if the buyer changes prices or service levels. “Revenue of the acquired business” is too loose. “Revenue from the customer schedule attached as Exhibit B, measured under the company’s pre-close revenue-recognition practice” is at least a real sentence.

EBITDA belongs only where EBITDA already belongs

EBITDA is appropriate when the business already trades and operates like an EBITDA story. That means management depth, real monthly reporting, and a company that does not need the owner’s personal labor to make the number. If you are still unclear on whether your company belongs in that category, read SDE vs EBITDA explained. Sellers who do not know which earnings language fits their company almost always accept the wrong trigger.

The danger is obvious. EBITDA looks objective until the buyer starts deciding what counts as overhead, what counts as integration cost, what gets reserved, what gets capitalized, and what gets pushed through the P&L. If the trigger is EBITDA, the accounting exhibit has to be nearly as important as the earn-out dollar itself.

Customer retention is often better than customer count

If the buyer is worried about whether key accounts stay, measure that directly. I prefer revenue-weighted retention from named customers, not raw client count. Losing ten small accounts and keeping the three largest ones is not the same economic outcome as losing one large account and keeping ten small ones. Yet sloppy earn-outs treat both cases the same.

This is where many sellers make a quiet mistake. They agree that “80% client retention” sounds fair, but the agreement never says whether that means by client count, by revenue, by gross profit, or by some weighted average. That is not a drafting detail. That is the earn-out.

Other metrics only work when they solve a specific problem

Gross profit, units shipped, backlog conversion, same-store sales, and renewal percentages all show up in the market. Some are legitimate. Most are dangerous unless the reason is obvious. If the company has a commodity pass-through element that distorts revenue, gross profit may be better. If the business is a niche manufacturer with predictable unit economics, units shipped may be fair. But unusual metrics should exist because they isolate the transfer risk, not because the buyer found a clever spreadsheet.

The clean seller-side question is simple: if this target is missed, will both parties agree it reflects real underperformance rather than measurement games? If the answer is no, the trigger is wrong.

Earn-Out Measurement Periods: Why One Year Is Usually Wrong

One year sounds neat. It also gets a lot of sellers into trouble. Most Indiana companies are not so smooth that one post-close year tells you what really transferred.

Seasonality is the first problem. Close an HVAC business in late fall, a landscaping company in December, a school-service business in summer, or an Elkhart manufacturer during an inventory correction, and a single 12-month period can capture more timing noise than true transfer performance. The seller ends up betting on the close date almost as much as the business.

Integration lag is the second problem. Buyers change systems, reporting, personnel, and sometimes branding in the first 90 to 180 days. Those changes may be reasonable for the buyer. They still distort the earn-out. A one-year period on a business that needs six months just to settle into the buyer’s platform is not a clean measurement period. It is a compressed experiment.

Take a representative Allen County HVAC company sold on November 1 with a $400,000 revenue-based earn-out for the “first full year after closing.” The buyer spends the first quarter re-routing technicians, changing dispatch software, and retraining office staff. By the time cooling season arrives, the business is still digesting the changeover. Miss the target by 4% and the seller learns too late that the earn-out measured integration quality as much as customer transfer.

What usually works better

• 18 to 24 months split into two tranches instead of one all-or-nothing test.
• Quarterly or semiannual reporting so the seller can see trouble before the deadline passes.
• Cumulative catch-up language so a slow first period can be fixed by a strong second period.
• Seasonal normalization or a close-date adjustment if the business has obvious annual swings.
• Linear payout formulas instead of cliff triggers that wipe out the entire payment for a minor shortfall.

One year is acceptable only when the transfer risk shows up quickly and cleanly, such as a named-account retention test on a tight customer list. Even then, I still prefer staged reporting and proportional payout. Sellers should not lose a full six-figure tranche because the metric landed at 79% instead of 80%.

Who Runs the Business During the Earn-Out Period

Most earn out M&A fights are control fights disguised as accounting fights. The seller says the buyer ran the business poorly. The buyer says the seller missed the target. Usually both sides are really arguing about who had the wheel.

If the buyer controls pricing, staffing, inventory, capital spending, marketing, customer assignment, and vendor strategy, then the seller needs operating covenants. Without them, the seller is being judged on a result the buyer can materially influence. That is not alignment. That is dependence.

There are three common post-close operating models. In the first, the buyer takes over immediately and the seller becomes available only for introductions. In the second, the seller stays in an operating role for six to twelve months. In the third, the seller stays as a consultant or transition executive while the buyer runs the platform. None of those is automatically wrong. They just require different earn-out protections.

Control points that need to be written, not assumed

• Whether the buyer must maintain reasonable staffing and working capital for the acquired business.
• Whether named customers can be reassigned to another affiliate or branch.
• Whether the buyer can materially change pricing, commission plans, or service standards during the earn-out period.
• What reports the seller receives, how often, and in what format.
• Whether the seller has inspection rights, meeting rights, or access to the general ledger supporting the calculation.
• What happens if the buyer terminates the seller without cause before the earn-out period ends.

If the seller stays on, define the job with the same precision you would use for a management hire. Hours, duties, reporting line, compensation, bonus treatment, and what counts as cause all matter. Sellers lose leverage when the buyer can fire them, claim transition support was inadequate, and keep the earn-out at the same time.

If the seller does not stay on, the metric should be even more objective. A seller who is no longer in the building should not be measured on subjective “successful integration” language or broad profitability tests that depend on buyer choices.

The Accounting Gotchas That Reduce Earn-Out Payments

This is where sellers usually discover that “GAAP” is not a complete answer. It is a starting point. The real issue is whether the earn-out is measured under GAAP, the company’s historical practices, a negotiated worksheet, or some buyer-defined adjusted version. Those are very different worlds.

Recent private-target deal-terms data has shown more buyers and sellers moving toward worksheet-style accounting instructions rather than vague “GAAP consistent with past practice” language. That is happening for a reason. Broad accounting language creates room for post-close interpretation, and post-close interpretation usually favors the party who controls the books.

The line items that move the goalposts most often

• Bad debt reserves. A buyer can get more conservative after closing and reduce EBITDA without changing collections reality.
• Inventory or warranty reserves. Especially in manufacturing and equipment-heavy deals, one change in reserve methodology can wipe out a tranche.
• Corporate overhead allocations. Shared HR, IT, finance, or executive costs suddenly appear after closing and depress the target.
• Revenue cut-off and deferred revenue. Timing changes can move sales or profit between periods.
• Integration costs. ERP onboarding, consultant fees, rebranding, or training costs get pushed through the business being measured.
• Capital expenditure versus expense treatment. The buyer books something as current expense and the seller watches EBITDA miss by the same amount.

Here is a representative miss. The earn-out target is $750,000 of EBITDA. The business finishes the year apparently close enough. Then the buyer books $60,000 of corporate IT allocation, increases bad-debt reserves by $45,000, records $35,000 of integration consulting cost, and changes inventory-obsolescence methodology by another $25,000. The seller thought the company was within striking distance. On paper, the target is now missed by $115,000.

That does not mean EBITDA triggers are impossible. It means the earn-out needs an exhibit that states exactly what is included, excluded, and calculated. If the definition says “EBITDA consistent with the company’s pre-close practices” but the buyer now runs a different chart of accounts, you do not have enough protection.

The seller-side fix is simple in concept and tedious in execution: attach the worksheet, define the ledger lines, ban specific allocations or one-time integration costs, require consistency with pre-close revenue-recognition and reserve practices unless a listed exception applies, and give disputes to an independent accountant rather than pure buyer discretion.

Escrow, Holdback, and Earn-Out: How They Combine or Conflict

Sellers often lump these together because all three delay or threaten payment. They are not the same thing. Escrow usually backs reps and warranties. A holdback is fixed money paid later after some cleanup item or short transition period. An earn-out is contingent consideration tied to performance. Confusing those buckets makes sellers accept more aggregate risk than they realize.

The real problem is stacking. Suppose a buyer offers $5.0 million, but the structure is 8% escrow, 7% holdback, and 15% earn-out. Suddenly 30% of the stated price is not in the seller’s account at closing. Add debt payoff, taxes, fees, and working-capital delivery, and the cash the seller actually controls on day one can be dramatically lower than expected.

That is why sellers should negotiate the entire delayed-consideration stack, not each piece in isolation. If the buyer insists on a meaningful earn-out, escrow usually needs to shrink. If the holdback is large, the earn-out should be narrow and objective. If the buyer wants all three at once, the seller should hear that for what it is: the buyer wants to keep leverage after closing.

The Double Lehman math is useful here. On a $5.0 million sale, Midwest Business Brokers’ Double Lehman fee is $300,000. If the buyer stacks a $400,000 earn-out on top of $400,000 of escrow and holdback risk, the delayed piece is already more than twice that fee. Sellers obsess over success fees and then casually agree to delayed-collection structures that are far more expensive.

What to Do If the Buyer Misses an Earn-Out Target

First, do not treat the buyer’s email summary as the calculation. Read the contract, the exhibits, and the definition section. Many sellers react to the conclusion before they reconstruct the formula. That is backwards.

1. Check the notice deadlines. Many earn-out agreements require the seller to object within a short window. Miss that deadline and the buyer’s statement may become final by default.
2. Freeze the data. Request the full calculation, supporting schedules, ledger detail, customer reports, and any operating reports the agreement entitles you to inspect.
3. Rebuild the metric under the contract language. Have your CPA or transaction accountant calculate the result the way the agreement actually defines it, not the way the buyer summarized it.
4. Test for buyer-caused misses. Compare staffing, pricing, allocations, customer movement, and operating decisions against any covenants in the agreement.
5. Use the dispute mechanism quickly. Most good agreements point accounting disputes to an independent accountant and covenant disputes to court or arbitration. Use the correct lane.
6. Decide early whether the right answer is enforcement, settlement, or amendment. Some misses should be fought. Some should be converted into a fixed payment or extended measurement period before the relationship gets poisoned.

Not every missed target is bad faith. Some earn-outs fail because the performance really was not there. But sellers get hurt when they assume the buyer’s first calculation is neutral, or when they wait until the objection period is gone before involving counsel and a CPA.

If you are already in that window, Schedule Your Confidential Consultation. Earn-out disputes are rarely solved by broad outrage. They are solved by contract language, accounting reconstruction, and speed.

Earn-Out Mistakes That Cost Indiana Sellers 20%+ of Deal Value

The biggest seller mistake is simple: treating the earn-out as upside instead of as risk-adjusted deferred price. Once you make that mental error, every other drafting mistake gets easier for the buyer to win.

Indiana tax mechanics matter too. The Indiana individual adjusted gross income tax rate for 2026 is 2.95%. County rates still vary materially. Effective January 1, 2026, Allen County is 1.59%, Hamilton County is 1.10%, Marion County is 2.02%, and Elkhart County is 2.00%. If your earn-out is paid in later tax years, split between consideration buckets, or tied to consulting or compensation language, your net proceeds model changes. Federal treatment depends on allocation and installment-sale rules, which is exactly why your CPA should model the whole waterfall before you sign.

Seller-side earn-out checklist before signing

• Keep the contingent piece modest. Once more than 20% to 25% of price is at risk, assume you are financing the buyer’s uncertainty.
• Do not accept an EBITDA earn-out without a line-by-line accounting exhibit.
• Avoid cliff triggers where missing a target by one point wipes out the full payment.
• Use 18 to 24 months for seasonal or cyclical companies instead of a single 12-month test.
• If customer transfer is the real issue, use named-account revenue or revenue-weighted retention rather than vague company-wide metrics.
• Write operating covenants around staffing, pricing, working capital, and account movement if the buyer controls the business.
• Protect against buyer-caused attrition, buyer overhead allocations, and post-close integration expenses.
• Do not let indemnity escrow, holdback, and earn-out stack without negotiating them together.
• Require acceleration or a fair alternative if the buyer sells the business again during the earn-out period.
• Compare the contingent offer to the lower all-cash offer on after-tax, after-fee, after-debt-payoff math, not on headline price.

Most owners do not need a lecture on theory. They need a seller-side answer to one question: if this buyer misses the earn-out, how much of my stated sale price was ever real? That is the question to ask before the LOI, before exclusivity, and definitely before closing.
