Earn-Out Agreements: How Earn-Outs Work When Selling a Business in the UK

An earn-out agreement is a deal structure in which part of the business sale price is deferred and paid to the seller over a period of time after completion, based on the future financial performance of the business. Earn-outs are one of the most commonly misunderstood and most hotly debated deal structures in business sales. For buyers they reduce the risk of overpaying for a business whose future performance is uncertain. For sellers they offer the potential to achieve a higher total consideration than a buyer would be willing to pay upfront, at the cost of performance risk and a continued connection to the business after sale. This guide explains how earn-outs work in UK business sales, when they are appropriate and what sellers need to understand before accepting one.

How Does an Earn-Out Work?

In a typical earn-out structure, the total sale price is split into two components. The first is the upfront payment, paid to the seller on completion of the legal transfer. The second is the earn-out, a deferred payment calculated by reference to the business achieving agreed financial targets over an agreed period after completion, typically one to three years. If the business meets or exceeds the targets, the seller receives the full earn-out. If it falls short, the earn-out payment is reduced proportionally or in some cases forfeited entirely depending on the specific terms negotiated.

For example, a buyer might offer a total consideration of one million pounds structured as seven hundred thousand pounds on completion plus up to three hundred thousand pounds in earn-out payments over two years, payable if the business achieves agreed annual profit targets. The seller receives the upfront element regardless of future performance. The earn-out element is contingent on the business continuing to perform at or above the agreed benchmark.

When Are Earn-Outs Used in Business Sales?

Earn-outs are most commonly used when there is a valuation gap between buyer and seller that cannot be bridged by negotiation on the upfront price alone. This typically occurs where the buyer is concerned that historical performance may not be sustained under new ownership, where the business is in a growth phase and the seller is seeking a premium valuation that reflects projected future performance, or where the business has significant customer concentration or key person dependency that the buyer wants to see resolved before committing to full payment.

Earn-outs are also used where the seller is expected to remain involved in the business post-completion in an operational or commercial capacity and the buyer wants to align the seller's financial interest with the continued performance of the business during the transition period.

Earn-Out Risks for Sellers

Earn-outs carry significant risks for sellers that must be understood and carefully mitigated through the legal documentation before completion. The most significant risk is that the buyer controls the business after completion and can make decisions that materially affect the earn-out calculation, including changing pricing, reducing marketing spend, reallocating overhead costs, integrating the business into a larger group or changing the accounting policies used to calculate profit. Without robust legal protections, a seller can find that the earn-out target is technically missed for reasons entirely within the buyer's control.

Other risks include the cost and complexity of monitoring and enforcing earn-out provisions, the difficulty of working alongside a new owner during the earn-out period, and the tax treatment of earn-out payments, which in some structures may be treated as employment income rather than capital gains, significantly affecting the net amount received.

How to Protect Yourself in an Earn-Out Agreement

If you agree to an earn-out, the legal documentation must include robust protections covering how profit is calculated and by whom, restrictions on the buyer's ability to make decisions that could artificially depress the earn-out metric, a clear dispute resolution mechanism, regular reporting obligations from the buyer, and explicit confirmation of the tax treatment of each earn-out payment. Always instruct a solicitor experienced in business acquisitions to negotiate and draft the earn-out provisions before you sign any binding agreement.

The upfront element of the total consideration should always be sufficient on its own to represent a fair outcome even if the earn-out is never paid. Never structure a deal where the upfront payment alone would leave you materially undercompensated for the business you have built.

Should You Accept an Earn-Out?

Whether to accept an earn-out depends on your specific circumstances. An earn-out may be worth accepting if the upfront element alone is a fair price for the business at its current level of performance, if you are willing and able to remain involved in the business during the earn-out period, if the earn-out targets are genuinely achievable and within your influence, and if the legal documentation provides robust protections. An earn-out should be rejected or heavily negotiated if the upfront element alone does not represent fair value, if you want a clean break from the business on completion, or if the earn-out targets are set at a level that makes them speculative rather than achievable.
