When would you recommend an earn-out, and what are the risks?
A core M&A Advisory interview question — asked in analyst and associate interviews across IB, PE, and the Big 4.
THE SHORT ANSWER
Recommend an earn-out when buyer and seller genuinely disagree on future performance and a structure can bridge the gap: high-growth or unproven businesses, founder-/management-dependent companies where you want to keep them invested and incentivized post-close, or where a specific milestone (a contract, a product launch, a regulatory approval) drives value. It defers part of the price, conditioned on the target hitting agreed metrics, shifting performance risk to the seller and aligning them with the forecast they're selling on. The risks are real and well-documented: a large share of earn-outs end in dispute, usually over measurement — how 'EBITDA'/revenue is defined and calculated post-close, how the buyer runs the business (integration, accounting changes, investment decisions that the seller claims suppressed the metric), and control. So draft precisely: define the metric and accounting basis, protect the seller's ability to hit it (covenants on how the business is run), set a clear measurement period and cap, and specify dispute resolution. Use it to bridge a value gap, not to paper over a fundamental disagreement.
WHAT INTERVIEWERS LISTEN FOR
- ✓Use to bridge a future-performance gap; keep founders incentivized
- ✓Defers price on agreed metrics; shifts performance risk to seller
- ✓Risk: ~30%+ end in disputes over metric definition/business conduct
- ✓Draft precisely: metric/accounting basis, run-the-business covenants, period, cap, dispute resolution
COMMON MISTAKES
- ✗Vague metric definition inviting disputes
- ✗No protection on how the buyer runs the business
- ✗Using it to mask fundamental disagreement
