Understanding Earn-Outs and Deferred Payments

In many UK business sales, the full purchase price is not paid on completion day. Instead, a portion of the consideration is deferred — paid after completion either on a fixed schedule or contingent on the business achieving specified performance targets.

Deferred Consideration

Deferred consideration is a fixed amount paid on agreed future dates, regardless of business performance. For example, 70% of the price paid on completion with the remaining 30% paid in two equal instalments at 12 and 24 months. The amount is certain; only the timing is deferred.

Earn-Outs

An earn-out is a portion of the purchase price that is contingent on the business achieving specified performance targets after completion. The seller only receives the earn-out payments if the agreed metrics are met. This creates a direct link between the seller's payout and the business's post-sale performance.

Earn-outs are commonly used when:

• Buyer and seller disagree on valuation — the earn-out bridges the gap
• The business is growing rapidly and the seller wants to capture future value
• The buyer needs the seller to remain involved to ensure continuity
• Funding constraints prevent the buyer from paying the full price upfront

A typical earn-out structure defines several key elements:

Performance Metrics

The most common metrics used in UK earn-outs are:

• Revenue: Simple to measure but can be manipulated through pricing or customer acquisition strategies
• EBITDA: Measures profitability but is affected by cost allocation decisions the buyer controls
• Gross profit: A middle ground — less susceptible to overhead manipulation than EBITDA
• Specific milestones: Contract wins, product launches, or customer retention targets

Typical Structures

• Duration: Most earn-outs run for 1-3 years. Longer periods increase uncertainty and risk for the seller
• Payment mechanics: Annual or semi-annual payments based on audited results against agreed targets
• Threshold vs sliding scale: Some earn-outs pay nothing below a minimum threshold; others increase proportionally with performance
• Caps and floors: Maximum and minimum payment levels provide certainty for both parties

The complexity of earn-out structures varies enormously. Simple, clearly defined structures with objective measurement criteria tend to work best. Overly complex arrangements create disputes and damage the post-sale relationship.

Advantages for Sellers

• Potential to achieve a higher total price than a pure cash deal
• Participation in future upside if the business continues to grow
• Can make the deal acceptable to a buyer who cannot fund the full price upfront
• Demonstrates confidence in the business's future performance

Risks for Sellers

• Loss of control: After completion, the buyer controls the business. Their decisions on investment, pricing, staffing, and strategy directly affect your earn-out
• Accounting manipulation: Buyers may allocate costs to the earn-out entity or make accounting adjustments that reduce reported performance
• Strategic changes: The buyer may prioritise long-term investment over short-term profitability, depressing earn-out metrics
• Integration disruption: Post-acquisition restructuring can temporarily reduce performance
• Counterparty risk: If the buyer's business fails, your earn-out payments may be at risk

For Buyers

Earn-outs reduce upfront risk and align the seller's incentives with business performance. However, they can create management challenges, restrict operational flexibility, and lead to disputes that damage the acquired business.

If you agree to an earn-out, robust legal protections are essential:

• Clear, objective metrics: Define exactly how performance will be measured, what accounting policies apply, and who prepares the calculations
• Operating covenants: Restrict the buyer from taking actions that could artificially depress earn-out performance — such as loading costs into the earn-out entity, diverting revenue, or underinvesting
• Ordinary course provisions: Require the buyer to operate the business in the ordinary course and not make material changes without your consent during the earn-out period
• Independent verification: Require earn-out calculations to be verified by independent accountants
• Dispute resolution: Include a clear mechanism (expert determination or arbitration) for resolving disagreements about earn-out calculations
• Information rights: Ensure you have the right to access financial information and management accounts throughout the earn-out period
• Security: Consider requiring the buyer to provide security for earn-out payments (parent company guarantee, escrow, or charge over assets)

Your solicitor should draft these protections into the SPA. Do not rely on verbal assurances from the buyer — if it is not in the contract, it does not exist.

Tax Treatment of Earn-Outs

The tax treatment of earn-out payments in the UK depends on how they are structured:

• Capital treatment: If the earn-out is structured as additional consideration for shares, payments are typically subject to Capital Gains Tax. Business Asset Disposal Relief may apply if conditions are met
• Income treatment: If earn-out payments are linked to the seller's continued employment or services, HMRC may treat them as employment income subject to income tax and National Insurance — a significantly worse outcome
• Ascertainable vs unascertainable: If the total consideration is ascertainable at completion (e.g., a fixed maximum), CGT is calculated on the full amount at completion. If unascertainable, the Marren v Ingles principle applies and each earn-out payment is a separate disposal

Specialist tax advice is essential before agreeing any earn-out structure. The difference between capital and income treatment can be enormous.

Alternatives to Earn-Outs

If you are uncomfortable with the risks of an earn-out, consider these alternatives:

• Higher cash at completion: Accept a lower total price in exchange for certainty — cash today is worth more than a promise of cash tomorrow
• Deferred consideration: Fixed payments on agreed dates, not contingent on performance. Lower risk than earn-outs
• Vendor loan notes: Structured debt from the buyer with agreed interest rates and repayment schedules, potentially with security
• Equity rollover: Retain a minority stake in the business and participate in future value creation alongside the buyer
• Retention payments: Separate consultancy or employment arrangements that compensate you for ongoing involvement without linking to business performance

The right structure depends on your risk appetite, tax position, and confidence in the buyer's ability to grow the business. At VAMOS, we advise sellers on the optimal deal structure to maximise value whilst managing risk. Book a confidential discussion to explore your options.
