What is an earnout?
An earnout is contingent consideration in an acquisition. The buyer pays an upfront amount at closing and promises additional payments if the business meets defined targets after closing. It is used when buyer and seller disagree on value, or when the future depends on something that cannot yet be proven.
An M&A advisor sees earnouts most often in lower-middle-market deals where the seller expects growth the buyer will not pay for in advance.
How does an earnout work?
- The parties agree an upfront price and a contingent amount.
- They pick a metric: revenue, gross profit, EBITDA, bookings, or a non-financial milestone.
- They set the measurement period, often one to three years, and whether targets are cumulative or annual.
- They write the accounting rules: which policies apply, what is excluded, how acquired revenue is treated.
- After each period the buyer prepares a statement, the seller reviews it, and disputes go to a named accountant or to the courts.
Terms vary widely, and the purchase agreement controls. This is general information, not legal, tax or financial advice. Confirm with your own counsel and tax adviser before acting.
Which metrics are used, and what goes wrong?
| Metric | Why parties pick it | Where disputes start |
|---|---|---|
| Revenue | Hard to manipulate, simple to audit | Buyer shifts customers to other entities; discounting |
| Gross profit | Aligns with margin quality | Cost allocation between old and new business |
| EBITDA | Reflects real profitability | Integration costs, management fees, owner pay |
| Bookings or backlog | Fits subscription and project firms | Definition of a booking; cancellations |
| Milestones | Fits product or licensing events | Whether the milestone was reasonably achieved |
Common disputes concern the buyer's operating freedom, accounting consistency, and one-off items. Sellers often ask for covenants to operate the business in good faith, while buyers resist limits on running their own company.
Earnout vs seller note
| Feature | Earnout | Seller note |
|---|---|---|
| Payment depends on performance | Yes | No, it is a debt owed |
| Seller bears business risk | Yes | Mostly buyer credit risk |
| Measurement disputes | Frequent | Rare |
| Typical use | Valuation gap | Financing gap |
Why does an earnout matter for a data license?
The collision is simple: a one-time license payment lands in the same income statement the earnout is measured on. Whether it counts is a drafting choice, and it is easy to leave unwritten.
Illustrative: a fictional IT services firm is sold with an earnout on year-two EBITDA. In year one the new owner licenses the firm's archived support tickets and project records through SourceX. The seller argues the one-time payment lifts EBITDA; the buyer argues it is non-recurring and should be excluded. With no clause, both readings are arguable and the accountant named in the agreement decides.
Settle it in the purchase agreement, in the metric definition, before anyone signs a licensing deal. A data license is typically exclusive for AI training for an agreed term, which is also why the buyer may want a say.
Checklist for the earnout definition
- Does the metric include or exclude one-time license proceeds?
- Who owns the right to license the company's records after closing?
- Does the buyer need the seller's consent, or the reverse, to sign a license during the earnout period?
- Is a license that is exclusive for AI training allowed under the operating covenants?
- Which accounting policies apply to license income, and who prepares the statement?
What this means for a referral partner
Partners introduce companies and share basic fit information only. A company mid-sale should involve its own deal counsel before anything else. Nothing is binding until the company agrees price and terms with SourceX and signs, and the licensing payment is made to the company, not deducted for the partner.
Partners earn 25% of the eligible platform fees SourceX actually collects, capped at $100,000 cumulative per referred company, paid only after the buyer pays and SourceX receives its fee. No reward is guaranteed. Read the program terms and check your own professional rules first.
