Earnout
 
In mergers and acquisitions (M&A), an "Earnout" is a pricing mechanism where part of the acquisition price is linked to the post-acquisition performance of the target company.

For buyers, it helps reduce uncertainty and risk; for sellers, it provides the opportunity to receive a higher total consideration if the business performs well. In other words, it bridges valuation gaps and allows risk-sharing between both parties.

This article explains the basics of Earnouts, how they are calculated, their pros and cons, and key points to watch out for when implementing them.
What Is an Earnout?
 
An Earnout is an arrangement in an M&A contract where part of the acquisition consideration is conditional on the future performance of the target company. In addition to the upfront payment made at closing, the buyer pays additional consideration only if the company meets pre-agreed targets, such as revenue, operating profit, or EBITDA.

Unlike a lump-sum payment, an Earnout is structured as contingent consideration, paid in installments based on measurable performance. The specifics—targets, formulas, and payment triggers—are clearly defined in the Earnout clause of the M&A agreement.
Why Are Earnouts Used?
 
In M&A deals, buyers aim to mitigate risk while sellers want to maximize valuation. This often leads to a gap in perception.

Earnouts help bridge this gap by tying additional payments to the achievement of financial metrics.
They are particularly useful in situations such as:
  • Start-ups with limited current results but high growth potential.
  • Biotech or technology firms, where success depends on uncertain milestones like regulatory approval.
  • Cross-border M&A, where market outlooks may differ between parties.

While Earnouts have been widely used in the U.S., adoption in Taiwan and Japan have been more limited. However, their use is increasing, especially in cross-border transactions.
How to Structure an Earnout: Metrics, Duration, and Payment
 
Performance Metrics
Common metrics include financial indicators such as revenue, operating profit, or EBITDA. In certain industries, non-financial KPIs such as user growth or new drug approvals may be used instead.

Calculation Methods
Earnouts can be designed in various ways, including:
  • Threshold model: profit-sharing of the portion that surpassed the target.
  • Tiered model: payments vary depending on different performance brackets.
  • Milestone model: fixed amounts are paid upon achieving specific goals, such as product launches.

Duration
The Earnout period usually ranges from 1 to 3 years. Longer periods risk being distorted by external market conditions, while shorter periods may not fully capture the company's potential. Around three years is considered a practical balance.

Payment Amounts
Final amounts and formulas are determined through negotiation, factoring in valuation gaps, risk allocation, and both parties's financial needs. Furthermore, it is common practice to set an upper limit (cap) on earnout amounts to limit the buyer's payment risk.
Pros and Cons of Using Earnouts
 
Benefits for Buyers
  • Reduces upfront cash burden by splitting payments.
  • Minimizes risk of overpayment if the business underperforms.
  • Distributes uncertainty between buyer and seller, helping deals close more smoothly.

Benefits for Sellers
  • Provides the chance to receive higher consideration if performance targets are achieved.
  • Allows future growth potential to be reflected in the transaction value.
  • Motivates owners who remain involved post-acquisition, as hitting targets results in extra rewards.

Drawbacks for Buyers
  • If performance greatly exceeds expectations, total payments may exceed initial estimates.
  • Monitoring and verifying performance increases integration (PMI) complexity and resource use.
  • Disputes may arise over accounting standards or definitions of metrics, potentially leading to litigation.

Drawbacks for Sellers
  • Consideration is received in installments, not in one lump sum.
  • If targets are missed, no additional payments are made.
  • Control shifts to the buyer after closing, meaning changes in strategy could impact performance outcomes.
Key Points to Consider When Implementing an Earnout
 
1. Clarity in Contract Terms
Performance indicators, calculation formulas, and payment triggers must be clearly defined to avoid ambiguity and disputes.

2. Balanced KPI Design
Avoid short-term profit bias by including a mix of financial and non-financial KPIs.

3. Reasonable Duration
Generally no more than three years to minimize exposure to external factors.

4. Resale Restrictions
Contracts may include clauses preventing the buyer from reselling the business during the Earnout period.

5. Expert Involvement
Because of accounting and tax complexities, it's essential to consult accountants and tax advisors during negotiations and drafting.
Conclusion
Earnouts play the role of both a risk-sharing mechanism and a valuation bridge in M&A transactions. They help buyers avoid overpayment while allowing sellers to capture future upside. At the same time, they introduce complexity in design, accounting, and contract negotiations.

For business owners considering Earnouts, success depends on:
  • Transparent and precise contract terms.
  • Realistic KPI and duration settings.
  • Guidance from experienced M&A, accounting, and tax professionals.

With careful planning, Earnouts can turn valuation disputes into win-win outcomes and pave the way for successful M&A deals.
