Earnouts: How They Work, When to Accept Them, and When to Fight
An earnout is how buyers pay you for a business they are not fully sure is worth what you are asking. It sounds like a compromise. In practice, it is a mechanism that transfers risk from the buyer to you — and then puts the buyer in charge of the variables that determine whether you get paid.
Earnouts are contingent consideration structures: a portion of the purchase price is deferred and paid only if the business hits specified performance targets after the sale. They are common in deals where the buyer and seller disagree on value — typically because the seller's projections show accelerating growth and the buyer is skeptical. Earnouts let both parties say they agreed on price while actually deferring the argument about what the business is worth into the post-close period, when the buyer controls the business and its accounting.
Understanding earnout mechanics before you negotiate them is essential. The difference between an earnout you can actually earn and one that looks good on paper but gets engineered away is almost entirely in the drafting.
What every seller needs to understand about earnout structure and risk:
- Buyers love earnouts for the same reasons sellers should be cautious about them. From the buyer's perspective, an earnout reduces upfront capital at risk, aligns the seller's incentives to stay engaged post-close, and creates a mechanism to pay less if the seller's optimistic projections do not materialize. From the seller's perspective, you are being asked to take credit risk on the buyer's willingness and ability to operate the business in a way that generates the targets — while no longer being the one making that call. Those interests are structurally in conflict.
- Revenue-based earnouts are generally better for sellers than EBITDA-based earnouts. EBITDA is an accounting construct that the buyer, post-close, controls. They can accelerate expenses, reallocate corporate overhead to your former entity, hire additional staff that reduces EBITDA, or change accounting policies in ways that compress the EBITDA line without affecting their overall performance. Revenue is harder to manipulate — it requires customers not to pay, which is a different set of decisions. When you must accept an earnout, push for revenue-based measurement with clear, narrow definitions of what counts as revenue for earnout purposes.
- The accounting control problem is the central earnout risk. Once the deal closes, the buyer controls the books. They decide how to allocate costs, when to recognize revenue, whether to invest in the business or harvest it, and how to structure intercompany transactions if your former business becomes a subsidiary. Each of those decisions affects EBITDA. Even buyers acting in good faith routinely make post-close operating decisions that reduce EBITDA in ways the earnout accounting captures — and those reductions cost you money. Buyers acting in bad faith have even more tools. The only protection is to define every term precisely and negotiate audit rights that let you verify the numbers independently.
- Earnout disputes are common and expensive. Studies of earnout-heavy M&A deals consistently show that a large minority end in formal disputes — either through contractual arbitration mechanisms, earnout audit exercises, or litigation. The disputes usually center on accounting treatment of specific items (was that a capital expense or an operating expense?), definition of the earnout metric (does revenue include returns? intercompany billings?), or buyer interference with the earnout period (did the buyer's decisions reduce performance?). The legal costs of an earnout dispute routinely run six figures and can exceed what the earnout was worth. Negotiate the definition and dispute resolution mechanism as carefully as the dollar amount.
- Clawback provisions and working capital adjustments compound the earnout risk. Some deals include both an earnout and a post-close working capital true-up. If actual closing working capital is below the peg, the seller pays back a portion of the upfront consideration. If earnout targets are missed, deferred consideration is not paid. A seller can end up with a lower upfront payment due to working capital adjustment and zero earnout payment due to missed targets — both on the same deal. Understanding all the moving parts in the economic waterfall of the purchase agreement, not just the headline number, is essential before signing.
- When an earnout actually makes sense for sellers. If your business genuinely has a pipeline of identified, contracted revenue that has not yet recognized but is highly likely to close — a signed government contract not yet earning, a new product launch with committed pre-orders — an earnout on that specific defined revenue is a reasonable bridge. The earnout period should be short (12 to 18 months maximum), the target should be based on events largely outside buyer control, and the measurement should be binary or mechanical rather than accounting-dependent. The cleaner the definition, the safer the earnout.
- Negotiating earnout mechanics is a separate skill from negotiating price. The earnout period (longer is riskier for sellers), the measurement metric (accounting-based vs. operational), the baseline (what counts as the starting point), the cap (maximum earnout payout), the acceleration provisions (what happens if the buyer sells again before the earnout expires), and the audit rights all deserve the same negotiating attention as the upfront consideration. Sellers who focus exclusively on the headline number and accept standard buyer-friendly language on the earnout mechanics often end up collecting 40 cents on every dollar the LOI implied.
- The best earnout protection is a smaller earnout. Pushing to minimize the earnout as a percentage of total consideration, front-loading more consideration at closing, and accepting a lower headline number in exchange for a cleaner deal structure is often the superior outcome. A deal at 4x EBITDA all-cash is frequently better than a deal at 5x EBITDA with a 20% earnout — because the 4x deal is certain and the 5x deal is subject to four years of execution risk, accounting disputes, and buyer control.
What it costs to accept earnout terms without understanding the mechanics: deferred consideration that never materializes, dispute costs that eat the earnout value, and years of post-close entanglement with a buyer who has no incentive to help you hit your targets.
What it earns you to negotiate earnouts carefully: earnout metrics you can actually influence, audit rights that keep the buyer honest, and a deal structure where the number in the LOI is the number you actually collect.
