Earnouts: Structuring Them to Minimize Risk
There’s a point in almost every M&A negotiation where the buyer leans back, folds their hands, and says something like, “We can get to your number… but we’ll need an earnout.”
If you’ve never been through a sale before, that might sound harmless—even encouraging. A path to closing. A way to bridge a gap. A vote of confidence in the future.
But if you’ve lived enough deal cycles, you know exactly what that sentence means:
We’re no longer negotiating the past.
We’re negotiating the future—and the future is where the risk lives.
Earnouts are one of the most misunderstood parts of the M&A process. Some founders see them as a carrot. Others see them as a trap. The truth sits somewhere in the middle: an earnout is simply a tool. Not inherently good, not inherently bad. Like any tool, it either protects value or destroys it depending on how it’s wielded.
When I sold Pepperjam, earnouts weren’t just a negotiating mechanism—they became a strategy. In fact, the willingness to restructure value into performance-based compensation led to one of the most profitable outcomes of my entire career. It’s a story I share often on the Legacy Advisors Podcast (https://legacyadvisors.io/podcast/) because it illustrates something foundational about M&A: the founders who win aren’t the ones who avoid complexity; they’re the ones who understand it.
And that’s why I wrote The Entrepreneur’s Exit Playbook (https://amzn.to/4n6Djb8)—to give founders clarity when the deal stops being clean and starts being human.
Let’s talk about how to structure an earnout so it doesn’t feel like a gamble, a penalty, or a hostage situation, but rather a strategic bridge to a better exit.
Why Earnouts Exist in the First Place
Founders typically hate earnouts. Buyers typically love them. And both sides have reason.
Buyers use earnouts to derisk what they don’t fully believe yet:
future growth, customer retention, margin stability, or scalability beyond the founder’s involvement. They want the business to prove itself post-close.
Founders resist earnouts because they’ve already lived the growth and proven the potential. They know how hard they’ve pushed to get to this point. And they don’t want a future they can’t fully control to determine the final value of the transaction.
The tension is natural.
But the presence of an earnout doesn’t mean your deal is weak.
It means your deal is complex.
And complexity is manageable—if you structure it intentionally.
Rule #1: Earnouts Should Measure What the Founder Can Actually Influence
This is where most founders accidentally trap themselves. They agree to earnouts based on metrics they no longer control: EBITDA under a new cost structure. Revenue under a new sales organization. Customer churn after the buyer changes pricing. Integration efficiency. Supplier terms the founder never negotiated.
Here’s the truth:
Earnouts fail when they measure outcomes influenced more by the buyer than the seller.
If you’re staying on for a transition period—6 months, 12 months, maybe longer—you need metrics tied to your stewardship, not to the company’s new identity post-acquisition.
In The Entrepreneur’s Exit Playbook, I stress that founders must negotiate for metrics that follow a single principle: alignment without dependency. You want the buyer aligned with the outcome but not in control of the outcome.
So what does that look like?
Revenue is often safer than EBITDA.
Gross profit is often safer than net profit.
Customer retention is safer than margin expansion.
Volume milestones are safer than integration milestones.
Anything that requires the buyer to “run the business well” is too risky.
Anything that allows the business to run naturally is safer.
Rule #2: Long Earnouts Kill Deals—Short Earnouts Protect Value
Buyers will always push for multi-year earnouts. It’s safer, it’s slower, and it mirrors their investment horizon. But long earnouts trap founders in limbo—not fully in, not fully out, not fully free.
Earnouts should be as short as possible.
Twelve to eighteen months is the sweet spot.
Anything longer begins to border on employment disguised as M&A.
A long earnout is also where resentment grows. Culture shifts. Integration friction. Operational changes. Turnover. All of these dynamics erode the founder’s ability to hit targets they set under a very different set of assumptions.
Ed and I talk about this all the time on the Legacy Advisors Podcast: rarely does a founder feel more trapped than when they’re two years into a three-year earnout, working harder than ever, even though they’ve already technically “sold the company.”
Short earnouts reduce stress, reduce variables, and give you a clean finish line.
Rule #3: Earnouts Should Reward the Upside—Not Replace the Base Price
Here’s where founders lose millions:
They allow buyers to shift too much of the purchase price into an earnout.
An earnout should be the second bite of the apple, not the apple itself.
If an earnout represents 10–25% of your total valuation, the risk is manageable.
If it’s 40–60%, you’re not selling your company—you’re refinancing your future.
Earnouts must be structured as performance bonuses, not baseline valuation drivers.
This is why the LOI is so critical. As I’ve said repeatedly in The Entrepreneur’s Exit Playbook and on the podcast, the LOI is where deals are won or lost. If you let a buyer push too much value into the earnout at the LOI stage, the final agreement will only tighten the noose.
Your base valuation should stand on its own merit.
Your earnout should be icing—not scaffolding.
Rule #4: Tie Earnouts to Clear, Auditable Numbers
Ambiguity is the enemy of earnouts.
If the buyer can interpret the metric two different ways, you will only hear the version that pays you less.
Every successful earnout shares one trait: it uses numbers that are clean, mechanical, and verifiable by a third party.
Examples of clear metrics:
• Revenue specifically from Product Line A
• Gross profit from existing customer cohort
• Number of units shipped
• New logos within a fixed ICP
• Specific milestones tied to expansion or retention
Examples of dangerous metrics:
• EBITDA under new cost structure
• “Synergy savings”
• “Integration milestones”
• “Cross-selling impact”
• Anything that requires subjective allocation of expenses
The clearer the math, the safer your outcome.
Rule #5: Get Your Earnout Paid Quarterly, Not Annually
One of the most practical pieces of advice I give founders is this:
Get paid early and get paid often.
Annual earnouts pack too much risk into a single measurement. A bad quarter, an unexpected economic shift, a staffing issue, a delayed vendor order—one event can erase twelve months of work.
Quarterly calculations distribute the risk.
They also keep everyone honest.
On the podcast, Ed often jokes that an annual earnout is the equivalent of a slot machine—“Come back next year and find out if you hit your number.” Quarterly earnouts feel more like a paycheck: predictable, incremental, and less tied to the whims of a single reporting period.
Rule #6: Earnouts Must Survive Founder Off-Ramps
What happens if:
You get sick?
Your spouse gets sick?
You step away earlier than expected?
The buyer reorganizes your role?
You get terminated without cause?
Your earnout should survive you.
A well-structured earnout is not employment-based—it is performance-based. If the company hits the numbers, you get paid, regardless of whether you’re still in the seat.
Founders make the mistake of believing buyers will “do the right thing.”
Buyers will do what the contract says.
Structure protects you from good intentions.
What Earnouts Reveal About a Deal
Earnouts reveal more about the deal than they resolve.
If a buyer wants an earnout because they’re derisking a genuine uncertainty—market volatility, seasonality, customer concentration—that’s healthy and honest.
If a buyer wants an earnout because they’re trying to reprice the deal through the back door, that’s a red flag.
Earnouts are X-rays. They expose motivations.
And if you listen closely enough, they tell you the truth about the buyer long before diligence does.
The Earnout That Changed My Life
I didn’t love the idea of restructuring parts of my Pepperjam exit into performance-based payments. But I felt confident in what we were building. I believed in the momentum. And most importantly, I understood the buyer’s psychology.
When eBay acquired GSI and the stock surged by more than 50%, the portion of compensation tied to future performance paid off in a way no one could have predicted.
That experience shaped a belief I still carry:
An earnout isn’t a burden if it’s built with intelligence, leverage, and foresight.
A well-designed earnout isn’t a risk—it’s an instrument of upside.
Find the Right Partner to Help Sell Your Business

Frequently Asked Questions About Earnouts and Founder Risk
1. Are earnouts something founders should avoid altogether, or can they actually benefit the seller?
Most founders assume earnouts are traps, and to be fair, they can be—when structured poorly. But not all earnouts are punitive. In fact, in The Entrepreneur’s Exit Playbook, I describe how the earnout tied to my Pepperjam exit turned into one of the most profitable outcomes of my career because the structure aligned perfectly with how the business naturally performed. Earnouts can protect you from buyers who want to discount the business unfairly, and they can unlock upside you’d never get in an all-cash deal. On the Legacy Advisors Podcast, Ed and I often say: earnouts aren’t good or bad—they’re tools. The key is ensuring the metrics are clean, the time frame is short, and the founder’s influence over the outcome is real. With the right structure, an earnout becomes leverage, not liability.
2. What’s the biggest mistake founders make when negotiating an earnout?
The biggest mistake is allowing the buyer to tie the earnout to metrics the founder can’t control—usually EBITDA, margin improvements, or integration milestones. Once the buyer takes over, they control spending, staffing, pricing, and operations. They can unintentionally (or intentionally) tank your ability to hit the earnout. In The Entrepreneur’s Exit Playbook, I call this the “illusion of influence”—founders think they’re still driving the business post-close, but structurally they aren’t. On the podcast, we talk often about the dangers of accepting earnouts tied to profitability instead of revenue or gross profit. The mistake isn’t agreeing to an earnout; the mistake is agreeing to an earnout you can’t meaningfully impact. If you can’t influence the metric, you shouldn’t agree to the metric.
3. How do I know if an earnout percentage is reasonable for my deal?
A healthy earnout is typically a small supplement to your base valuation—something in the 10–25% range. When earnouts climb beyond 30–40%, the deal stops being a sale and starts becoming a gamble. I’ve seen buyers try to shove 50–60% of value into an earnout, which is almost always a red flag. In The Entrepreneur’s Exit Playbook, I stress that the base price should stand on its own. The earnout should be the upside—not the foundation. On the Legacy Advisors Podcast, Ed and I regularly tell founders that too large an earnout signals either misaligned expectations or a buyer who isn’t fully confident in the numbers. A reasonable percentage is one that feels like a reward—not a hostage situation—and still allows you to walk away with certainty and dignity.
4. What protections should founders negotiate to make an earnout enforceable and fair?
Earnouts only work when the rules are clear, objective, and insulated from manipulation. That means you need protections around accounting methods, buyer interference, reporting frequency, and what happens if the buyer reorganizes the business. In The Entrepreneur’s Exit Playbook, I outline why quarterly measurement is often safer than annual—it reduces the risk of one bad quarter derailing the entire earnout. You also need clarity on how revenue is attributed, how expenses are allocated, and what happens if you’re terminated without cause. On the podcast, Ed and I emphasize that earnouts should survive the founder. In other words, even if you step away or the buyer shifts roles internally, the earnout should still pay if the business hits the numbers. Structure eliminates ambiguity, and ambiguity is where earnouts go to die.
5. How do earnouts impact founder psychology after the sale?
Earnouts create a strange emotional state: you’ve sold your company, but you’re not done yet. Many founders describe it as living in two worlds—part owner, part employee, part outsider looking in. It’s why short earnouts (12–18 months) are almost always healthier than long ones. In The Entrepreneur’s Exit Playbook, I explain that long earnouts often lead to resentment because the founder’s identity is tied to goals they no longer fully control. On the Legacy Advisors Podcast, Ed and I talk about “earnout fatigue”—the grinding sense that you’re working on borrowed time. Well-structured earnouts reduce that emotional burden by aligning incentives, shortening the window, and creating transparency. The psychological impact is real, but when the structure is right, the earnout becomes a motivating runway rather than a draining obligation.
