Earnout in a Business Sale: What Buyers and Sellers Should Define Before Closing

A buyer and seller can agree that a business has strong future potential while disagreeing about how much of that potential should be paid for today.

An earnout is one way transactions sometimes bridge that gap.

Instead of paying the entire amount at closing, part of the purchase consideration becomes payable only if the acquired business meets specified future performance conditions.

Earnouts can solve valuation disagreements, but they can also create difficult post-closing disputes if the terms are vague.

The legal, tax, and accounting consequences are transaction-specific. Buyers and sellers should obtain qualified professional advice before agreeing to an earnout.

What Is an Earnout?

An earnout is contingent purchase consideration based on future performance or another agreed milestone.

The payment may depend on measures such as:

• Revenue
• EBITDA or another earnings measure
• Gross profit
• Customer retention
• Specific contracts
• Operational milestones

Why Do Buyers Use Earnouts?

A buyer may believe the seller’s future projections are possible but be unwilling to pay for them entirely at closing.

An earnout can shift part of that risk back to the seller.

Why Would a Seller Accept an Earnout?

A seller may believe the business will perform strongly after closing and may accept contingent consideration in order to:

• Bridge a valuation gap
• Support a higher total potential purchase price
• Complete a deal that otherwise might not close

The seller should still distinguish between guaranteed cash at closing and contingent future value.

1. Define the Performance Metric Precisely

“Profit” can mean many things.

If the earnout depends on earnings, the agreement should define exactly how earnings are calculated.

Questions may include:

• Which expenses are included?
• How are corporate overhead charges treated?
• How are owner or management salaries treated?
• How are one-time expenses handled?
• What accounting principles apply?

2. Revenue-Based Earnouts Can Be Simpler—but Still Need Rules

Revenue may appear easier to measure than profit.

But questions can still arise around:

• Returns
• Credits
• Intercompany sales
• Bundled products
• Revenue recognition

3. Establish the Measurement Period

The earnout may operate for one year, several years, or another negotiated period.

A longer period can increase the seller’s potential upside while also extending uncertainty.

4. Define Payment Timing

The agreement should state when performance is measured and when earned amounts become payable.

For example, payment may occur after annual financial statements are completed and any dispute period expires.

5. Understand Who Controls the Business After Closing

This is one of the most important issues.

The buyer generally controls the company after closing, yet the seller’s earnout may depend on how the buyer operates it.

That creates potential tension.

6. Address Operating Covenants Carefully

A seller may seek protections against actions that could intentionally or unintentionally reduce the earnout.

The buyer may resist restrictions that prevent normal business decisions.

The agreement may address issues such as:

• Budgeting
• Customer allocation
• Product changes
• Business integration
• Expense allocation

7. Define the Seller’s Post-Closing Role

The seller may remain as:

• Employee
• Consultant
• Advisor
• Transition executive

The role should be coordinated with the earnout so the parties understand what responsibility the seller has for achieving the targets.

8. Consider What Happens if the Seller Leaves Early

If the seller resigns, is terminated, becomes disabled, or dies, the agreement should explain whether the earnout changes.

The answer should not be left to assumption.

9. Address Business Integration

A strategic buyer may integrate the acquired company into a larger organization.

That can make standalone performance difficult to measure.

If an earnout depends on the acquired company’s results, the agreement should anticipate integration where possible.

10. Define Access to Financial Information

The seller may need sufficient information to verify the earnout calculation.

The agreement can address reporting and review rights while protecting the buyer’s broader confidential information.

11. Create a Dispute Process

Earnout calculations can produce disagreements.

The agreement may establish:

• Notice procedures
• Review periods
• Negotiation requirements
• Independent accountant procedures
• Other dispute mechanisms

12. Consider Caps, Thresholds, and Maximum Payments

An earnout may provide:

• A maximum amount
• A minimum performance threshold
• Graduated payments
• All-or-nothing milestones

The economics should be modeled before closing.

13. What Happens if the Buyer Resells the Business?

The buyer may sell the acquired company before the earnout period ends.

The agreement should address whether a later sale:

• Accelerates payment
• Terminates the earnout
• Transfers the obligation
• Has another negotiated effect

14. Earnout Is Different From Seller Financing

A seller note generally creates a payment obligation under agreed financing terms.

An earnout depends on future performance or another condition.

A transaction can include both.

15. Earnout Is Also Different From Escrow

Escrow generally holds consideration that has already been negotiated but remains subject to claims or release conditions.

An earnout typically represents additional consideration that becomes payable only if defined future requirements are satisfied.

Tax Treatment Requires Professional Review

Contingent purchase consideration can create complex tax consequences.

The structure, payment timing, employment relationship, and asset or equity treatment can all matter.

Tax advice should be obtained before final terms are accepted.

Sellers Should Value the Earnout Conservatively

A headline purchase price that includes a large earnout should not be viewed the same as cash received at closing.

Sellers should distinguish among:

• Cash at closing
• Seller financing
• Escrow
• Earnout
• Other contingent amounts

Define the Earnout Before Closing

An earnout can be useful when the parties genuinely disagree about future performance.

It becomes dangerous when broad phrases such as “seller receives additional payment if the company performs well” are left without precise definitions.

Transaction counsel can help buyers and sellers address metrics, accounting, control, seller involvement, information rights, dispute procedures, and payment mechanics before the purchase agreement is signed.

Frequently Asked Questions

What is an earnout in a business sale?

An earnout is contingent purchase consideration that becomes payable if the acquired business meets specified future performance or milestone requirements.

Is an earnout guaranteed money for the seller?

No. Payment depends on the conditions defined in the purchase agreement, so sellers should distinguish earnout value from cash received at closing.

What should an earnout agreement define?

It should clearly address the performance metric, calculation method, measurement period, operating assumptions, seller role, reporting, payment timing, and dispute procedures.

Earnouts can bridge valuation differences, but the performance metric, calculation rules, operating control, and payment process should be defined precisely.
