THIS MONTH'S FOCUS
An Earnout Is Not a Seller Note
An earnout is not a seller note. It is not a holdback, a clawback, or a generic way to make the buyer feel better about what they might discover after close. An earnout is a specific tool for a specific situation: the seller still has meaningful influence over the outcome being measured.
An earnout can make sense when the current owner is staying involved for a defined transition period, especially when the buyer is relying on that owner's customer relationships, operating judgment, sales leadership, customer demand, or technical knowledge. It can also make sense alongside rollover equity, where the seller remains economically exposed to the future value of the business rather than walking away with all cash at close.
The structure becomes fragile when the seller is no longer involved in the drivers being measured, or when the metric is tied to factors outside the seller's practical influence. In lower middle market M&A, the question is not whether contingent consideration is fair. The question is whether the person being asked to earn the money can still affect the business after close.
But if the seller is not involved in the customer, demand, or operating drivers being measured, the earnout becomes something else. It asks the seller to bet on factors they may no longer influence. It asks the buyer to accept the risk that the seller's pre-close story was incomplete. And it gives both sides a clean narrative for why the other side is responsible when the number is missed.
That is not alignment. That is a dispute waiting for a calendar date.
The Earnout Is Viable When the Seller Can Still Affect the Result
There are deals where an earnout is exactly the right tool.
The founder is staying for two years to transition customer relationships. The owner remains president of the acquired business while the buyer professionalizes finance, systems, and reporting around them. Or the seller steps out of day-to-day management but remains in a consulting or advisory role, helping retain key accounts, transfer relationships, maintain customer confidence, and support demand continuity through the ownership change. The seller's relationships with a handful of large customers are central to the transfer of value. The buyer needs to know that revenue will not disappear the moment the wire clears.
In that fact pattern, an earnout can create real alignment. The seller has a role. The seller has access. The seller can influence the outcome. If the metric is tied to customer retention, revenue from named accounts, renewal activity, qualified introductions, sales pipeline transfer, customer demand stability, a transition milestone, or a defined operating handoff, the earnout is not just a deferred price argument. It is a compensation mechanism for successful transition.
Rollover equity can work for similar reasons, although it is a different instrument. The seller is not merely waiting to be paid on a short-term metric. The seller remains invested in the future enterprise value of the business. That can be powerful when the seller is genuinely aligned with the buyer's plan and understands the rights, liquidity, and governance attached to the rolled stake.
The common thread is influence. If the seller can still help create the outcome, contingent consideration may be a useful structure.
The Problem Starts When the Metric Leaves the Seller's Influence
The structure becomes fragile when the seller exits the relevant workstream and the buyer controls the operating environment.
After close, the buyer decides how to staff the business, how to price, how to manage customers, what systems to implement, which expenses to allocate, whether to replace managers, whether to integrate the company into a platform, and how much capital to invest. Those decisions may be entirely reasonable. They may also move the earnout metric.
That is why EBITDA earnouts are so fragile. EBITDA is not a natural fact. It is a managed number. Revenue can be affected by pricing decisions, customer transition quality, salesforce changes, service levels, and the buyer's integration approach. Gross margin can be affected by sourcing, inventory, freight, labor, and allocation rules. The seller may say the buyer mismanaged the business. The buyer may say the seller overstated the durability of the business. Both may believe they are right.
The deeper issue is disclosure. Lower middle market businesses often carry risks that do not show up cleanly in a quality of earnings report or management presentation. A key customer is more fragile than the seller suggested. A sales relationship sits with the owner, not the company. A margin profile depends on vendor favors that are not contractual. A process works because one employee has been quietly holding it together for twelve years. Deferred maintenance, undocumented pricing exceptions, weak controls, customer concentration, and employee dependency often become visible only after the buyer is inside the business.
When those issues surface, a traditional earnout does not balance the risk well. It turns the buyer's post-close discovery problem into a fight over whether the seller would have earned additional money if the buyer had run the business differently.
A Seller Note Can Be a Better Risk-Sharing Tool
If the concern is hidden downside, a seller note may be a cleaner structure than an earnout.
A seller note starts from a different premise. The seller is financing part of the purchase price. The buyer owes that amount over time, subject to the agreed terms. If the parties want to share specific post-close risks, the note can include defined reductions, offsets, holdbacks, or clawback-style mechanics tied to objective outcomes.
The note does not do that work automatically. The reduction right has to be negotiated into the documents, tied to defined facts, and protected against buyer-created underperformance. Otherwise a seller note is simply deferred purchase price with credit risk, not a risk-sharing mechanism.
That is different from asking the seller to earn upside in a business they no longer influence. The buyer is not saying, "You get paid more if we hit a number." The buyer is saying, "We will pay this deferred portion unless specific risks that were part of the deal thesis fail to hold."
The distinction matters.
For example, if the seller represented that key customers were stable, part of the note could be tied to retention of named customers over a defined period. If the business depends on recurring revenue, the note could step down if revenue from identified accounts falls below a stated threshold for reasons not caused by the buyer's own conduct. If the seller is transitioning relationships, the note can be tied to completed introductions, customer acknowledgments, renewal activity, or other evidence that the relationship actually transferred.
The same logic can apply to receivables, backlog conversion, warranty claims, margin leakage, or other specific risks. The point is not to punish the seller for ordinary business volatility. The point is to keep both sides honest about the assumptions embedded in the purchase price.
The Metric Has to Match the Risk
The worst structure is a broad earnout metric used to solve a narrow trust problem.
If the buyer is worried about customer concentration, use a customer-retention mechanism. If the buyer is worried about collectability, address receivables. If the buyer is worried about backlog quality, test conversion. If the buyer is worried that the owner personally owns the relationships, define the advisory or transition obligations and measure whether those relationships actually moved.
Do not use EBITDA as a catch-all substitute for unfinished diligence. EBITDA is too exposed to buyer-controlled decisions. It creates room for both parties to argue about what would have happened in a world no one can prove.
The same caution applies to seller notes. A performance-adjusted seller note only works if the adjustment is specific, measurable, and protected against buyer manipulation. The buyer should not be able to intentionally starve the business and reduce the note. The seller should not receive full payment if the deal was priced on customer relationships, backlog, or margin quality that did not actually survive close.
That is the balance. Protect the buyer from undisclosed or misunderstood risk. Protect the seller from being penalized for buyer decisions outside the seller's control.
The Better Deal Structure Question
The question is not, "How do we bridge the valuation gap?"
The better question is, "Which party can influence the risk after close?"
If the seller stays involved and can influence performance, an earnout may be the right answer. If the seller rolls equity and remains aligned with the next chapter, rollover may be part of the answer. But if the seller is not involved in the customer, demand, or operating drivers being measured, and the buyer is worried about what they will discover after close, the cleaner answer may be a seller note with clearly defined adjustment rights.
In lower middle market M&A, structure should follow influence and control. Earnouts are for seller-influenced upside. Seller notes and holdbacks are for buyer-protected downside. Confusing the two is how a purchase price compromise becomes a post-close dispute.
KEY FRAMEWORK - M&A DEAL STRUCTURE
The Influence-Based Deal Structure Test
A structured way to decide whether an earnout, seller note, rollover equity, or holdback actually matches the risk being allocated.
Seller involvement: Will the seller have an operating, consulting, or advisory role after close, with real influence over the metric? If yes, an earnout may be viable. If no, be careful.
Risk source: Is the buyer trying to pay for upside that the seller can help create, or protect against downside that may be discovered after close? Those are different problems.
Metric controllability: Can the metric be moved by buyer decisions on pricing, staffing, integration, accounting, or capital investment? If yes, avoid broad EBITDA-based earnouts and consider customer-specific transition metrics instead.
Seller note mechanics: If the seller is financing part of the purchase price, define any reductions, offsets, or clawbacks around specific risks such as customer retention, receivables, backlog conversion, margin leakage, customer demand erosion, or transition failures.
Rollover alignment: If the seller rolls equity, confirm the seller understands governance, liquidity, rights, dilution, and the buyer's value creation plan. Rollover is not the same as cash deferred with interest.
Dispute protection: Define data access, measurement periods, buyer conduct standards, caps, cure rights, and dispute resolution before close.
The core principle: Structure should follow influence and control. Use earnouts for seller-influenced upside. Use seller notes, holdbacks, and defined adjustment rights for buyer-protected downside.
