How Earnouts Work in Agency Acquisitions

An earnout ties part of your payout to future performance. Here's how they're typically structured, why buyers use them, and what to watch for as a seller.
An earnout is a piece of your total deal value that's contingent on the business hitting specific performance targets after close, instead of paid entirely at closing. Buyers use them constantly in agency deals, and understanding the mechanics protects you far better than accepting the structure because it's common.
Why buyers use earnouts
An earnout reduces the buyer's risk on future performance and, done well, aligns both sides around the same outcome. If a seller is confident the business will keep performing, an earnout should feel like upside, not a discount. If a seller is less confident, the earnout is the mechanism a buyer uses to bridge that gap instead of just lowering the headline price.
I'd rather sellers think of an earnout as a growth incentive tied to a story you both believe, not a consolation prize for a lower cash number at close.
What typically gets tied to an earnout
Revenue retention or growth targets, EBITDA thresholds, and sometimes client retention on specifically named accounts if concentration was a known risk factor in the deal. The metric matters enormously: vague or poorly defined metrics are where earnout disputes come from later.
What to watch for as a seller
Check whether the metrics are within your influence after close, or depend on decisions the buyer now controls (staffing, budget, service changes) that you no longer have authority over. An earnout tied to a metric you can't influence post-close is a much riskier structure than one tied to something substantially in your control.
How this connects to client concentration and founder dependence
If your agency had meaningful client concentration or founder dependence going into the deal, expect the buyer to lean harder on earnout structure to manage those risks, with retention targets tied to your top clients, for example. This is one more reason to fix those factors before you sell, rather than during negotiation. It gives you more leverage over the final structure.
Common mistakes
Sellers focus entirely on the headline price and underweight how much of it is contingent, and on what. A deal that looks larger on paper can be substantially smaller in practice if a meaningful share is earnout tied to metrics outside your control.
Earnout terms are specific to the transaction and the jurisdiction. Have your own M&A attorney review any structure before you rely on it.
Frequently Asked Questions
Is an earnout a sign the buyer doesn't trust me?
Not necessarily. Earnouts are standard practice in agency M&A, used to bridge normal uncertainty about future performance, not exclusively as a red flag about the seller.
Can I negotiate the metrics in an earnout?
Yes, and you should. The metrics themselves, and how much control you retain over the factors that drive them, matter as much as the headline earnout amount.
What happens if I don't hit the earnout targets?
It depends entirely on how the agreement is written. Some structures pro-rate partial achievement, others are all-or-nothing at a threshold. Your attorney should review this detail closely before you sign.
Should I ever refuse a deal with an earnout?
Not automatically. A well-structured earnout tied to metrics you can genuinely influence can be a legitimate part of a strong deal. Be more cautious of one tied to factors you won't control post-close.
