The headline number is bigger than the founder expected. Then the structure page arrives: 45 percent of the price is payable over three years if the business hits targets the buyer will measure, inside a company the buyer will run. The offer is not the headline. The offer is the wire at closing plus a bet on someone else’s management.
What is an earnout and why do buyers offer them?
An earnout is a portion of the purchase price paid only if the business hits agreed targets after closing, usually measured over 1 to 3 years. The buyer pays part of the price at the wire and promises the rest against future performance.
Buyers favor earnouts because earnouts transfer performance risk to the seller. If the business underperforms after the buyer takes control, the buyer’s effective price falls automatically, with no renegotiation required.
Earnouts also let the buyer fund the purchase from the target’s own results. Revenue the founder’s team generates after closing pays the founder’s own deferred consideration, which limits the buyer’s capital at risk to the cash at close.
When 30 to 60 percent or more of the headline sits in an earnout, the structure is doing the pricing. Windsor Drake’s guide to handling an inbound offer treats a heavy earnout as a valuation signal rather than a bonus.
How should a founder value an earnout offer?
Cash at close is the price. The earnout is at-risk upside controlled by the counterparty, and a founder should decide whether to sell as if the earnout pays zero. A founder who would refuse the deal at the cash-at-close number should refuse the deal.
Control is the whole analysis. After closing, the buyer owns the business and sets every budget that drives the earnout metric, while the founder holds a contract claim on numbers the founder no longer produces.
Serial acquirers use heavy earnouts to widen The Proprietary Discount, the gap between what an unbanked bilateral deal pays and what a competitive process clears. That gap runs 15 to 25 percent of enterprise value, and Windsor Drake tracks it in The Windsor Drake Proprietary Discount Index. Competitive pressure converts earnout into cash at close faster than any drafting argument.
Which mechanics decide whether an earnout pays?
The metric decides most outcomes. A revenue metric is safer for the seller than an EBITDA metric because the buyer controls costs after closing, and allocated overhead or new integration expense can erase EBITDA without a single lost customer.
Operating control comes next. The buyer that sets pricing and headcount for the acquired unit effectively sets the earnout result, which is why written operating covenants matter more than the target number itself.
Integration moves the metric on its own. Migrating customers to the buyer’s platform or folding the sales team into a larger organization changes revenue attribution, and an earnout without attribution rules pays whatever the buyer’s accounting says.
Two more terms decide the edge cases. Acceleration determines what happens if the buyer resells the business or terminates the founder during the earnout period. The dispute forum determines whether a disagreement means an independent accountant on an expedited schedule or litigation measured in years.
What are standard earnout terms in lower-middle-market tech?
Horizons run 1 to 3 years. Shorter horizons favor the seller because integration noise compounds over time and every additional year adds buyer decisions the seller cannot control.
Revenue or bookings metrics for the acquired product line are the seller-safe standard in software deals. EBITDA earnouts appear in buyer paper because EBITDA is the number the buyer can manage downward through cost allocation.
Whether earnout structure is even worth accepting depends on the buyer set. Windsor Drake’s analysis of whether a founder needs a banker covers how a single bilateral buyer keeps structure heavy while competing bidders shift consideration toward cash.
Which earnout terms should a founder negotiate?
Cap the earnout share first. Every point moved from earnout to cash at close is worth more than any improvement in earnout mechanics, because certain money beats contingent money at the same nominal amount.
| Earnout term | Seller-favorable form | Buyer-favorable form to resist |
|---|---|---|
| Metric | Revenue or bookings of the acquired product line, with written attribution rules | EBITDA or net income after allocated corporate overhead |
| Horizon | 1 to 2 years | 3 or more years spanning deep integration |
| Payout curve | Linear payout from a low floor, with partial credit for partial performance | All-or-nothing cliff at a single target |
| Operating control | Written covenants keeping the seller running the unit on a protected budget | “Sole discretion” language for the buyer’s operation of the business |
| Acceleration | Full acceleration on resale of the business or termination of the founder without cause | No acceleration; the earnout dies quietly on a change of control |
| Reporting and disputes | Quarterly metric statements, seller audit rights, independent accountant resolution | Annual buyer-prepared statements with the buyer’s calculation final |
How does the LOI lock the earnout in?
The letter of intent is where earnout mechanics get fixed or lost. An LOI that leaves the earnout at “terms to be agreed” hands the drafting to the buyer during exclusivity, after the founder has stopped talking to other buyers. Standard exclusivity asks run 30 to 90 days, and one in three signed LOIs fails to close on original terms. Windsor Drake’s guide to the letter of intent covers what must be written before signing: metric definition, payout curve, operating covenants, audit rights, and acceleration triggers.
How does an advisor change the earnout?
Competition converts structure into cash. When two or more qualified buyers bid, earnout share falls and cash at close rises, because heavy structure is how a buyer wins a deal it is underpaying for. Windsor Drake processes reach 40 to 80 qualified buyers, and a process alongside a live offer takes 4 to 6 months.
The fee math favors the check. Success fees run 4 to 6 percent below 10 million dollars of enterprise value and 2 to 4 percent between 10 and 50 million, detailed in what an M&A advisor costs, against a structure that puts a third or more of the headline at risk.
A founder holding an earnout-heavy offer can test the structure against the market without losing the buyer. Windsor Drake’s Approach Response engagement runs that competitive check alongside a live offer in 4 to 6 months.
Questions founders ask
Is a revenue or EBITDA earnout better for the seller?
Revenue. The buyer controls costs after closing, so allocated overhead or integration expense can erase an EBITDA target without any loss of customers. A revenue or bookings metric with written attribution rules is the seller-safe structure.
How should a founder value an offer that is half earnout?
At the cash at close. The earnout is at-risk upside controlled by the buyer after closing, and the decision to sell should hold even if the earnout pays zero.
What happens to the earnout if the buyer sells the company again?
Without an acceleration clause, the earnout can die on resale because the new owner never agreed to the targets. Sellers should require full acceleration on resale of the business or on termination of the founder without cause.
Can earnout terms be fixed after the LOI is signed?
Negotiating power drops sharply at signature because exclusivity removes competition. One in three signed LOIs fails to close on original terms, so the metric, the operating covenants, and the acceleration triggers belong in the LOI itself.
Why do buyers offer earnouts instead of more cash?
Earnouts transfer performance risk to the seller and let the buyer fund part of the price from the target’s own post-closing results. Both effects lower the buyer’s real price without lowering the headline.
Who controls the business during the earnout period?
The buyer, by default. After closing the buyer sets budgets, pricing, and staffing for the acquired unit, which is why written operating covenants and seller audit rights decide whether an earnout is real consideration or a discount in disguise.
