How Should Founders Structure an Earnout in an Acquisition?

Earnouts are one of the most misunderstood — and most dangerous — elements of any acquisition deal. Most founders walk into negotiations treating the earnout as a number to haggle over. The more important question is whether to accept one at all.

The Core Problem: Earnouts Transfer Risk Back to the Founder

Buyers love earnouts precisely because they work in the buyer's favor. The moment you hand over the keys, you lose the operational leverage that made those numbers achievable in the first place. Control shifts. Costs get loaded. Leadership changes. And suddenly the targets you agreed to are nearly impossible to hit.

One experienced operator who had sold a company put it bluntly: "Earnouts are almost always set up to fail. Anecdotally, and through having worked on a lot of these deals, nine out of ten earnouts fail completely."

That pattern is consistent with what surfaces repeatedly in founder exit post-mortems.

Rule 1: Push Hard for Maximum Cash at Close

Every dollar sitting in an earnout is a dollar you may never collect. Before debating earnout structure, exhaust every option to convert that deferred consideration into upfront cash.

• Buyers propose earnouts to reduce their risk — that is their function
• The founder's job is to price that risk into the upfront number instead
• If a buyer won't move on cash at close, that tells you something about their confidence in the business they're acquiring

Rule 2: Cap the Earnout Below 20–25% of Total Deal Value

Once an earnout climbs above roughly 20–25% of total deal value, it stops functioning as upside and starts representing core deal value you are unlikely to receive.

That is the trap. A founder who believes they are selling for $20M but has $8M in earnout has not sold for $20M. They have sold for $12M with a lottery ticket attached.

"Every dollar in the earnout is a dollar you might never collect. Buyers know this. That's why they love earnouts — they shift risk back to you the moment you hand over the keys."

Rule 3: Tie Metrics to Things You Can Actually Control Post-Close

The choice of earnout metric matters as much as the number itself.

Why Revenue Beats EBITDA

• EBITDA is easy for a buyer to manipulate by loading in new overhead, shared-services allocations, or management fees
• If the buyer installs their own leadership and restructures the cost base, your EBITDA target becomes fiction almost immediately
• Revenue or gross margin dollars are harder to manipulate and more directly tied to what the acquired team actually drives

Questions to ask before accepting any metric:

• Who controls pricing decisions after close?
• Who controls headcount and cost allocation?
• Will acquired customers be migrated to the buyer's platform or contracts?
• Does the buyer have the right to redirect sales resources?

If the honest answer to any of these undermines your ability to hit the target, negotiate the metric or negotiate it out.

Rule 4: Get Secured Creditor Status in Writing

This is the clause most founders never think to ask for — and the most expensive omission.

One founder hit 100% of his earnout targets on a significant deal. The buyer simply could not pay. Because he was an unsecured creditor, he had no legal priority over other obligations. He ultimately had to buy his own company back at a steep discount.

Hitting your targets and still not getting paid is not a theoretical risk. It happens.

What to do:

• Require that earnout obligations are secured against specific assets
• Have your M&A attorney document creditor status explicitly in the purchase agreement
• Do not assume goodwill or a strong relationship provides any protection at all

Rule 5: Ask the Buyer for References From Founders Who Received Earnouts

Before signing, ask the buyer to connect you with two or three founders from prior acquisitions who had earnouts and actually collected them in full.

A buyer with a track record of honoring earnouts will be able to produce names quickly. A buyer who cannot — or who deflects — has given you a meaningful signal.

This one ask costs you nothing and filters for a very specific kind of counterparty risk.

The Bottom Line on Earnout Structure

The right earnout structure starts with minimizing how much of your deal lives in an earnout at all. If you cannot avoid deferred consideration, the negotiation is about control, metrics, security, and counterparty track record — not just the dollar figure on the term sheet.
