What Is an Earnout in M&A and How Does It Work?
When a buyer and seller cannot agree on what a business is worth, they do not always walk away from the table. Instead, they often reach for a mechanism that lets both sides share the risk of getting valuation right over time. That mechanism is an earnout in M&A, one of the most useful and most misunderstood tools in any deal negotiation. For business owners considering a sale, understanding how an earnout in M&A works can mean the difference between leaving money on the table and structuring a deal that reflects your company’s real potential.
What Is an Earnout in M&A?
An earnout in M&A, formally called contingent consideration, is a structure where the buyer pays an agreed upfront amount at closing and then makes additional payments to the seller later, but only if the business hits specific post-closing targets. Those targets can be financial, like reaching a defined revenue figure or EBITDA level, or non-financial, like securing a regulatory approval or winning a key customer. The earnout in M&A bridges the gap between what a seller believes the business is worth and what a buyer is willing to pay upfront given uncertainty about future results.
Why Earnouts Come into Play
Earnouts appear most often when there is a meaningful valuation gap between buyer and seller. Sellers navigating an earnout in M&A in fast-growing sectors such as technology, healthcare, and startups often have strong conviction that performance will improve after the deal closes. Buyers prefer to pay for results they can already see on paper, not projections they are being asked to trust. The earnout in M&A resolves this by tying part of the purchase price to actual post-acquisition performance. An earnout in M&A is also more common in private company transactions, where financial disclosures are less standardized and information gaps between parties tend to be wider.
How Earnout Milestones Are Structured
The earnout in M&A can be designed in several ways depending on the business and what both sides care about most. Revenue milestones are the most widely used, where additional consideration is paid if the business crosses defined revenue thresholds over a set period, typically one to three years after closing. EBITDA-based milestones follow the same logic but measure profitability rather than top-line growth. Non-financial milestones are common in pharma or technology deals, where a patent grant, product launch, or key personnel retention may matter more than short-term numbers.
The seller’s role during the earnout period matters too. In many structures, the founder stays on actively, directly influencing whether targets are met. In others, the seller’s involvement is limited, making them dependent on the buyer running the business in a way that supports milestone achievement.
Benefits and Risks of an Earnout in M&A
For sellers, an earnout in M&A creates the opportunity to earn more than a buyer would agree to upfront if the business performs as expected, and can significantly increase total deal value. For buyers, the earnout in M&A reduces upfront risk and aligns the seller’s interests with post-deal performance, which is especially valuable when the founding team stays involved.
That said, earnouts carry real risk for sellers. Once the deal closes, the buyer controls daily decisions that directly affect whether milestones get hit. Disputes over earnout calculations are among the most common sources of post-deal friction. Sellers must pay close attention to how milestones are defined, who controls the relevant decisions, and what protections are built into the agreement.
Key Takeaways for Business Owners
Before agreeing to an earnout in M&A, keep the following in mind.
- Ensure milestones are specific, measurable, and not subject to the buyer’s unilateral discretion.
- Understand which operating decisions will affect your targets post-closing.
- Get independent legal and advisory support to review the earnout structure before signing.
- Consider the earnout in M&A period length, since longer windows increase uncertainty for sellers.
- Clarify what happens if targets are partially met, not just fully hit or missed.
