Earnout timing can change the result
The length and start date of an earnout affect both probability and control.
Two earnouts with the same target and maximum payout can have very different values if their measurement periods differ.
A short period may reduce exposure to the buyer’s long-term decisions, but it can make the result unusually sensitive to closing timing, seasonality, delayed orders, or a temporary disruption. A long period may smooth those effects, yet it also extends the seller’s dependence on an organization the seller no longer controls.
Define exactly when measurement begins. Does the period start at closing, the next calendar month, or the beginning of a fiscal year? How is a partial month treated? If the company has a seasonal cycle, a stub period can distort the comparison with historical performance.
The agreement should also state whether targets are annual, cumulative, or tested separately in each period. A cumulative structure may allow one strong year to offset another weak year. Separate annual tests can create a missed payment even when total performance over the full term exceeds plan.
Consider events that interrupt the original plan. What happens if the buyer resells the company, combines it with another division, discontinues a product, terminates the seller, or changes the reporting calendar? Acceleration, deemed achievement, or an alternative calculation may be appropriate in defined circumstances.
Timing is not a drafting detail. It determines which operating events count and how long the seller remains exposed to them.
