Earn-outs appear in many sales of owner-led companies. A portion of the purchase price is paid later, conditional on the business reaching agreed targets after closing. For buyers, an earn-out shares the risk of an optimistic forecast. For sellers, it can unlock a higher total price than a buyer would pay upfront.
Earn-outs can work well. They can also become the most contentious part of a transaction, long after the champagne is finished. The difference usually lies in how carefully they are designed.
Why earn-outs exist
Earn-outs usually solve one of three problems:
- A valuation gap. The seller believes in growth the buyer is not yet willing to pay for.
- Owner dependency. The buyer wants the seller to stay engaged during a transition.
- Uncertainty. A large contract, a new product or a recovering market makes the near future hard to predict.
If none of these applies, an earn-out may not be needed. It is reasonable to ask a buyer why they are proposing one.
The core trade-off
Every euro or franc moved into an earn-out is a euro or franc you may not receive. It depends on future performance under someone else's ownership. A higher headline price with a large earn-out is not necessarily better than a lower price paid in full at closing. Owners should compare offers on a risk-adjusted basis, considering how likely the targets are and how much control they will have over reaching them.
Design questions that matter
What is measured?
Revenue is simple to measure but can encourage growth at any cost. Profit-based measures, such as EBITDA, reflect quality but are exposed to decisions the buyer makes on costs, allocations and integration. Gross profit, customer retention or specific milestones can be alternatives. The best metric is one that is clearly defined and hard to influence through accounting choices.
Over what period?
Shorter periods reduce uncertainty for the seller. Longer periods give buyers more protection. Most owners prefer a period short enough that the business still resembles the one they sold.
How are targets set?
Targets should be grounded in the plan the buyer used to value the business. If the buyer believes the forecast enough to pay for it, they should be comfortable linking the earn-out to it.
All or nothing, or sliding scale?
A cliff structure, where missing a target by a small margin means receiving nothing, creates tension. A sliding scale, with partial payment for partial achievement, is generally fairer and reduces disputes.
What about integration?
If the buyer plans to merge your company into theirs, measuring standalone performance becomes difficult. Agree in advance how the business will be run and accounted for during the earn-out period, or consider whether an earn-out is suitable at all.
Protections sellers commonly seek
The specific terms are a matter for your legal advisers, but owners typically discuss:
- Clear accounting definitions, ideally with worked examples
- Commitments on how the business will be operated during the period
- Restrictions on changes that would distort the measured result
- Information rights so the seller can follow progress
- Acceleration if the business is sold again or materially restructured
- A defined mechanism for resolving disagreements
None of these removes risk entirely, and each needs to be drafted carefully. Legal and tax advice is essential, as the treatment of deferred consideration differs between jurisdictions.
Common mistakes
- Focusing on the headline number. The upfront payment is what is certain.
- Accepting vague definitions. Ambiguity in the agreement becomes conflict in the third year.
- Agreeing to targets you do not control. If the buyer controls pricing, staffing and investment, your influence is limited.
- Underestimating the personal cost. Working towards an earn-out under a new owner can be demanding, especially when priorities diverge.
Alternatives worth considering
Depending on the situation, other tools can bridge a gap with less friction: a vendor loan, a retained minority stake, a deferred fixed payment, or simply a smaller earn-out combined with a stronger upfront offer generated by a more competitive process.
Running the earn-out period well
Once an earn-out is agreed, the way both sides behave during the measurement period matters as much as the drafting. Owners who manage it well tend to:
- Agree a simple reporting format with the buyer at the start, so results are visible monthly rather than discovered at the end
- Raise concerns early and in writing if decisions seem likely to affect the measured result
- Keep a record of key decisions and their reasons
- Maintain a constructive relationship with the new management, even when priorities differ
Buyers, for their part, benefit from a motivated former owner. A respectful, transparent earn-out period usually produces better results for everyone than one conducted at arm's length.
How LXN works with owners
We help owners evaluate offers on what they are likely to receive, not just what is written in the headline, and negotiate structures that are clear and fair. Our hands-on work before a sale often reduces the need for an earn-out in the first place, by addressing the risks that make buyers ask for one.
