Earn-Outs in M&A

A Flexible Way to Bridge Valuation Gaps Without Delaying the Deal

In many M&A transactions, the hardest part of the negotiation is not finding a buyer or aligning on strategy. It is agreeing on what the business is worth today versus what it could be worth tomorrow.

Sellers often believe the future growth of their company should be reflected in the purchase price. Buyers, on the other hand, prefer to pay based on current financial performance and proven results.

When those perspectives collide, deals can stall.

One solution that frequently keeps transactions moving forward is an earn-out structure. When designed correctly, an earn-out allows both sides to move forward with confidence by sharing in the future upside of the business.

But like many M&A tools, earn-outs are powerful only when structured carefully.

In this guide, we break down how earn-outs work, when they make sense, and how business owners can evaluate whether one is truly beneficial in their situation.

What Is an Earn-Out?

An earn-out is a portion of the purchase price that is paid after the closing of a transaction, based on how the business performs over a defined period of time.

Rather than receiving the full sale price upfront, part of the payment is tied to the company achieving specific financial or operational milestones.

A simplified example might look like this:

Purchase Structure

• $20 million paid at closing• Up to $5 million additional earn-out over the next 1–3 years• Payments triggered if the company hits agreed-upon revenue or EBITDA targets

If the company meets or exceeds those performance benchmarks, the seller receives the full earn-out payment. If results fall short, the payout may be reduced or eliminated.

From the buyer’s perspective, this structure reduces risk.From the seller’s perspective, it creates an opportunity to capture value that may not yet be reflected in the company’s current financials.

Why Earn-Outs Exist in M&A Deals

Earn-outs are most commonly used when there is a valuation gap between the buyer and seller.

This happens more often than many founders expect.

A seller might believe their business is about to enter a period of strong growth. Perhaps they have:

• A new product launch approaching• A major contract about to close• Expansion into a new geography• A recently built sales pipeline that has not yet converted into revenue

The buyer may recognize the potential but still hesitate to pay fully for something that has not happened yet.

Earn-outs allow the deal to move forward without forcing either side to abandon their view of the business’s value.

Instead of debating the future, both parties agree to measure it.

When Earn-Outs Make Strategic Sense

Earn-outs are not appropriate for every deal. However, they can be extremely effective in certain situations.

At Vermilion Rock, we typically see earn-outs used successfully when several of the following conditions exist.

1. There Is a Clear Valuation Gap

If the buyer and seller are relatively close in price but cannot fully bridge the gap, an earn-out can unlock the transaction.

Instead of delaying the deal for another year of financial results, both sides agree to tie part of the value to future performance.

2. The Seller Plans to Stay Involved

Earn-outs work best when the seller remains active in the business after closing.

This might include roles such as:

• CEO or operating executive• Strategic advisor• Division leader for a product or geography

When the seller has real influence over the company’s performance, the earn-out structure becomes much more balanced.

3. Growth Catalysts Are Already in Motion

Some companies are on the verge of major milestones that simply have not yet appeared in historical financial statements.

Examples include:

• Launching a new product line• Entering a high-growth market• Expanding manufacturing capacity• Securing a large customer contract

In these cases, an earn-out allows sellers to participate in the value created by those upcoming catalysts.

4. Both Parties Want to Move Quickly

Sometimes the timing of a transaction matters more than squeezing out every dollar of immediate value.

Owners may want to:

• Reduce personal risk• Diversify wealth• Bring in strategic resources for growth• Begin succession planning

Earn-outs can help move the deal forward today while still capturing some of the future upside.

Common Earn-Out Structures

Earn-outs are usually tied to objective performance metrics that both parties can measure clearly.

The most common benchmarks include:

Revenue Targets

Payments triggered when the business reaches specific revenue thresholds.

This approach is common in high-growth companies where top-line expansion is the primary focus.

EBITDA or Profit Milestones

Many buyers prefer earn-outs based on profitability rather than revenue alone.

This ensures that growth is occurring alongside sustainable margins.

Customer or Contract Retention

In industries where long-term contracts drive value, earn-outs may depend on retaining key clients.

For example:

• Maintaining enterprise contracts• Renewing subscription customers• Preserving long-term supply agreements

Operational or Product Milestones

In some cases, earn-outs are tied to strategic objectives rather than pure financial metrics.

Examples might include:

• Launching a new product successfully• Expanding into a new market• Completing a major infrastructure investment

The most successful earn-outs rely on metrics that are clearly defined, objectively measurable, and difficult to manipulate.

The Risks of Earn-Outs

Despite their benefits, earn-outs can introduce complexity and potential conflict if they are poorly structured.

Some of the most common challenges include:

Misaligned Incentives

If the buyer changes strategy after the acquisition, the actions needed to hit earn-out targets may no longer be prioritized.

Limited Seller Control

If the seller is no longer involved in the business, their ability to influence performance may be limited.

Accounting Disputes

Even small differences in accounting treatment can affect whether earn-out thresholds are technically met.

Unrealistic Targets

Sometimes earn-out goals are overly optimistic, making it unlikely the seller will ever receive the additional payments.

These risks do not mean earn-outs should be avoided entirely. They simply reinforce the importance of clear structure and thoughtful negotiation.

How to Protect Yourself in an Earn-Out Agreement

If an earn-out is part of your deal structure, several safeguards can improve the likelihood of a successful outcome.

Define Metrics Clearly

All performance benchmarks should be precisely defined.

Avoid ambiguous language around revenue recognition, expense allocation, or accounting adjustments.

Establish Transparent Reporting

The agreement should specify:

• How performance will be measured• How often results will be reported• Who verifies the calculations

Ensure Reasonable Targets

Earn-out thresholds should reflect realistic business performance, not aggressive projections used during negotiations.

Align Operational Control

If the earn-out depends on company performance, the seller should ideally retain some influence over the areas that determine success.

Work With Experienced Advisors

Earn-outs involve financial, operational, and legal considerations.

An experienced M&A advisor and legal team can help ensure the structure protects your interests while keeping the deal attractive to buyers.

The Bottom Line

Earn-outs can be an effective tool for unlocking transactions that might otherwise stall during valuation negotiations.

When structured properly, they allow buyers and sellers to:

• Bridge valuation gaps• Align incentives around future growth• Share in the upside of the business• Move forward with a transaction without waiting years for financial results to catch up

However, the success of an earn-out depends heavily on clear terms, reasonable expectations, and aligned incentives between both parties.
