Earn-out and Price Adjustment Mechanisms in M&A
How earn-outs and price adjustment mechanisms work in M&A deals, and what FDD analysts need to understand about their structure and risks.
Earn-outs and price adjustment mechanisms are used when buyers and sellers cannot agree on value at signing. They are common in deals where future performance is uncertain, or where the seller believes the business is worth more than the buyer is willing to pay upfront. As a TS analyst, you will encounter earn-out provisions in SPAs and may be involved in calculating them post-closing.
What Is an Earn-Out?
An earn-out is a contingent component of the deal price that the seller receives only if the business meets agreed performance targets after closing. It defers part of the consideration and aligns seller incentives with post-closing business performance.
Typical Structure
- Earn-out period: Usually one to three years post-closing
- Performance metric: Typically EBITDA, revenue, or a sector-specific KPI
- Cap and floor: Maximum and minimum amounts the seller can earn
- Payment timing: Annual or at the end of the earn-out period
Example
A company is sold for a base price of €30m, with an earn-out of up to €5m if EBITDA exceeds €5m in the first year post-closing. If EBITDA reaches €4.5m, the earn-out may be zero. If it reaches €6m, the full €5m is paid.
Why Earn-Outs Are Contentious
Earn-outs frequently lead to post-closing disputes because:
- The buyer now controls the business and can influence the reported EBITDA
- Cost allocations, management decisions and accounting policies can all affect the metric
- Sellers often feel the buyer is managing the business in a way that minimises the earn-out
TS advisers are sometimes appointed post-closing to calculate earn-out payments and resolve disputes — a lucrative service line.
Price Adjustment Mechanisms
Separate from earn-outs, price adjustment mechanisms correct the deal price based on balance sheet items at closing:
Completion Accounts Adjustment
As described in the locked-box vs. completion accounts framework: if net debt or NWC at closing differs from the agreed reference figures, the price adjusts accordingly.
NWC Peg
If NWC at closing is €1m above target, the seller receives an extra €1m. If it is €1m below target, the buyer deducts €1m from consideration.
Net Debt True-Up
If net debt is higher than estimated at signing, the equity value falls and the buyer pays less.
The FDD Analyst's Role
In deals with earn-out provisions, the TS team may be asked to:
- Review the accounting policies used to calculate the earn-out metric
- Prepare or review earn-out calculations annually during the earn-out period
- Provide an independent assessment if disputes arise
- Advise on the earn-out definition to ensure it is unambiguous in the SPA
Key Risks to Flag in Due Diligence
- Ambiguity in the metric definition: "EBITDA" in an earn-out must be precisely defined in the SPA, including how adjustments are calculated.
- Buyer influence post-closing: The FDD team should flag whether management has significant discretion over the earn-out metric.
- Accounting flexibility: If the earn-out uses EBITDA and the company has judgment-heavy accounting items, the risk of manipulation increases.
Conclusion
Earn-outs and price adjustments are deal engineering tools with significant accounting and valuation implications. A TS analyst who understands them deeply can add real value in transactions and post-closing work.
