Earnouts: How to Structure Them So You Actually Get Paid

Almost every founder who signs an earnout believes they will hit the targets. Most don’t. Some of that is the unpredictability of running a business under new ownership. A lot of it is the structure of the earnout itself: targets that were never realistic, definitions that gave the buyer too much control, and the absence of protections that would have made the contingent payment something you could actually count on. If a buyer asks you to take part of your purchase price as an earnout, you are not powerless. You just need to negotiate the document as if you assume you will fight over every dollar of it, because eventually you might.

Why Earnouts Get Negotiated in the First Place

Earnouts exist because the buyer and the seller disagree about the future. The seller believes the trajectory of the business justifies a higher multiple. The buyer is not willing to pay for performance they have not seen. An earnout bridges the gap by tying part of the payment to results the seller projected. It is, at its best, a fair way to share risk. At its worst, it is a way for buyers to discount the headline price by twenty or thirty percent and never pay the difference.

Pick Milestones That Actually Hold Up

The single most important choice in an earnout is what you measure. Revenue is usually a better metric than EBITDA, because EBITDA is calculated by the buyer’s accountants and is subject to accounting judgments that you no longer control. If the buyer insists on EBITDA, push for a fixed methodology in the agreement: specific addbacks, specific allocation rules for shared corporate costs, no changes in accounting policy without seller consent.

Non-financial milestones, such as customer retention targets or product launches, can be even more dangerous. They sound objective, but they depend entirely on the buyer’s execution. If the milestone is launching a product, who controls the engineering team? If it is retaining a customer, who owns the customer relationship?

Who Runs the Company Determines Whether You Get Paid

The most important earnout protection is operational control. If you are staying on as CEO of the acquired business with the same authority you had before, your earnout has a fighting chance. If you are being moved into a non-operational role, or if the buyer has the right to integrate the business into theirs, the earnout is largely out of your hands.

At minimum, you should have written commitments about who has hiring authority for the business, who can change pricing, who can shut down or sell off product lines, and what the marketing and R&D budgets will be during the earnout period. The agreement should require the buyer to operate the business consistent with past practice unless you agree otherwise.

Anti-Manipulation Covenants

Even with operational control, you need explicit anti-manipulation protections. The buyer should agree not to take actions whose primary purpose is to reduce the earnout payment. Examples to spell out: no accelerating expenses into the measurement period, no deferring revenue past it, no diverting customers to affiliated businesses, no charging the acquired business above-market intercompany fees.

These are not theoretical risks. Litigation over earnout manipulation is one of the most common kinds of post-closing M&A litigation. The clearer the contractual standard, the less you have to litigate over what the buyer actually intended.

Acceleration Triggers

Build in events that accelerate the earnout to its full value. The standard list includes a change of control of the buyer, termination of your employment without cause, a material breach of the operating covenants, and the sale or shutdown of the acquired business line. Without these triggers, a buyer can dismantle the business or fire you and you lose the earnout entirely.

Consider also a true-up mechanism. If the earnout is measured over three years and you miss the first year’s target by a small margin but exceed the second year’s target by a large margin, you should be able to recoup the missed payment through cumulative performance.

Tax Treatment Matters as Much as the Structure

Earnout payments are typically taxed as ordinary income or imputed interest, not as capital gains on the original sale. That tax delta can be material. A seller who collects a one-million-dollar earnout payment over three years can pay fifteen to twenty percent more in federal tax than they would have on an equivalent up-front payment. The fix is to negotiate the earnout as additional purchase consideration with imputed interest at the applicable federal rate, not as bonus or compensation. Document the intent in the agreement, and have your accountant model the after-tax outcome before you sign so that you understand what the real number actually is to you.

Dispute Resolution Mechanics

Earnout disputes are common, and they are expensive. Build in a structured dispute resolution mechanism that does not start with full litigation. A typical structure: the seller has the right to inspect the books and records supporting the earnout calculation within sixty days of the buyer’s certificate, disputed amounts are submitted to an independent accounting firm for binding determination, and the prevailing party recovers fees. Without this structure, every dispute becomes a lawsuit, and every lawsuit takes two to four years.

Earnouts Are Not Free Money

If you are tempted to accept an earnout because the headline number sounds good, run the math both ways. What is the deal worth if you collect every dollar of the earnout? What is it worth if you collect none of it? If the answer to the second question is materially below what you would accept as an all-cash deal, the earnout is not a bonus on top of the price. It is a discount the buyer is hoping you won’t fully realize.
