Before I sold my company, I had breakfast with the CEO of a multi-billion-dollar building materials distributor. He brought up earnout insurance. I had never heard of it. He told me it was late in the game but worth exploring.
So I looked into it. Earnout insurance is real, and most sellers have never heard of it.
When I bring it up, most sellers want to know three things: what it costs, how you get it, and when it's worth a look.
What it is
The people who sell it call it contingent risk insurance. When it covers deferred purchase price, you'll also hear earnout insurance or contingent purchase price insurance. It sits in the same transactional-risk family as reps and warranties (R&W) insurance, but it's a different policy with different underwriters.
The key point for sellers: "earnout insurance" can mean two very different policies.
| Policy | What it protects against | Availability |
|---|---|---|
| Payment protection | You hit the target and the buyer doesn't pay because of insolvency, refusal, or a covenant breach | Easier to get, cheaper to buy |
| Performance protection | The business misses the target and the earnout never triggers | Rarely offered; very expensive when it is |
Most sellers want performance protection. The market mostly sells payment protection. Insurers will take on a buyer's credit risk or a dispute over a milestone you clearly met. They almost never insure your post-close EBITDA, because that depends on decisions they can't see or control.
Why payment risk is real
The PE firm isn't always the one who owes you. In a lot of deals, the earnout is owed by the portfolio company the PE firm bought, not by the PE fund. If that company runs out of cash, the fund has no legal duty to pay you unless it signed a guarantee.
- You don't need a bankruptcy to lose the payment. If the company breaks a loan term, the lender can freeze the earnout. That happens more often than outright default.
- The risk builds over the earnout period. At about 2% a year, a three-year earnout carries roughly a 5–6% chance of default. Counting lender freezes, my guess is closer to 8–10%.
- If the company fails, you're near the back of the line. Senior lenders get paid first, and in a bankruptcy an unsecured earnout often recovers little.
A real-world example
Insured earnout claims almost never become public because the policies and claims are confidential. The best-known public case shows exactly the risk sellers are trying to cover.
When Johnson & Johnson bought Auris Health in 2019, a large part of the price was an earnout tied to FDA milestones. After closing, J&J folded Auris's robotics platform into a competing internal program and never paid the earnout. The former Auris stockholders had to take J&J to court to get paid. They won in the Delaware Court of Chancery, and in January 2026 the Delaware Supreme Court upheld the core of that ruling.
The sellers won, but it took more than five years of litigation. That's the risk earnout insurance is meant to transfer. It also shows the limit: an insurer would have fought over whether the buyer's conduct was covered or was a permitted business decision.
What it costs
Price depends on which risk you're insuring. Expect a single upfront premium plus fees, with a minimum premium that hurts small deals most.
| Coverage | Typical premium | Other costs |
|---|---|---|
| Payment protection (buyer default, non-payment) | About 2–4% of the earnout amount, per one market overview | Underwriting fee, broker fee, retention of about 0.5–1% of deal value |
| Contingent risk in general (litigation, tax, regulatory) | 8–15% of the limit purchased, per WTW | Taxes on top; terms written for each risk |
| Performance-linked coverage on a small earnout | Can reach 30–40% of the limit in premium or collateral | Often declined outright |
Why small deals don't work: Carriers set minimum premiums, commonly quoted at $50,000 to $150,000 or more. On a $1M earnout, the minimum premium alone is 5–15% before fees. Add performance risk and pricing climbs much higher. At that level, you're better off negotiating the earnout itself.
Treat any published rate as a starting point. Every policy is custom, and pricing comes from a broker indication on your actual deal.
How to get it
What underwriters want to see:
- An earnout large enough to justify the minimum premium, generally $500,000 or more
- Objective milestones such as revenue, signed contracts, or regulatory approvals
- Tight accounting definitions and buyer covenants not to undermine the earnout
- A track record for the metric you're being measured on
What they exclude: targets the business simply misses, operational changes the purchase agreement allows the buyer to make, subjective or EBITDA-heavy metrics, and seller fraud.
When it's worth a look
If the earnout is large, the metric is clean, and your main worry is getting paid, call a broker. If not, save the fee.
| Factor | Worth pricing | Probably skip it |
|---|---|---|
| Earnout size | $3M or more | Under about $1M |
| Metric | Revenue, contract wins, approvals | EBITDA, margin, anything the buyer controls |
| Your real worry | Buyer can't or won't pay | Business might miss the number |
| Buyer | Leveraged, thinly capitalized, or offshore | Well-capitalized strategic |
| Agreement | Tight definitions, operating covenants, audit rights | Loose "reasonable efforts" language |
Most lower-middle-market earnouts land in the right-hand column.
What to do instead
When insurance isn't worth it, protect the earnout in the purchase agreement. These protections usually cost less and cover more.
- Escrow or holdback: Part of the earnout is set aside at close and released when milestones hit.
- Parent guarantee or letter of credit: Someone creditworthy stands behind the buyer's payment obligation.
- Operating covenants: Limits on what the buyer can change during the earnout, such as pricing, headcount, or integration.
- Clear definitions: Spell out the accounting and give examples of how the metric is calculated.
- Independent accountant: A neutral third party calculates the number or settles disputes.
- Acceleration triggers: The full earnout pays out if the buyer sells the business, breaches a covenant, or terminates you without cause.
- Shorter, simpler earnouts: Fewer years and one metric leave less room for a dispute.
