How Earnouts Work in Optometry Practice Sales
When you first see an offer for your optometry practice that includes an earnout the offer price can look incredible. It feels like a massive win because someone is finally putting a real dollar value on all those years of hard work. We are talking about the late nights and the stress of paying staff when the schedule was thin and the money you constantly spent on new equipment just to stay competitive. But then you look closer at the fine print and the reality sets in. Well you realize the buyer isn't just handing you a check for the full amount and letting you walk away today. Instead they are paying you a part of it at the closing table and the rest is "earned" over the next one to three years. That second part, the earnout, is basically just a performance bonus. And that is where the real decision begins.
At DVMElite, we have sat across from plenty of owners who were thrilled about the total value of their deal only to realize later that a big part of their money was not actually guaranteed. Look, earnouts are not always bad and they are often just a way to build a deal but that structure determines whether your retirement feels like a clean break or a period of total uncertainty.
The bottom line is this: If you do not know exactly what triggers that earnout payment you are not really evaluating the deal. You are just guessing and you are basically betting on your ability to hit someone else's targets while you are no longer the one in total control.
The Emotional Reality of the "Second Number"
Selling an optometry practice is one of the most important financial decisions you will ever make. It is not just a business transaction because it represents decades of work and responsibility and leadership that most people outside the profession will never fully understand. When an offer comes in we often see owners focus on the "offer number" because it feels like a win. If you built a practice from $500,000 to $2 million that $2 million figure is your validation but an earnout changes the nature of that validation.
If $500,000 of that $2 million is tied to an earnout you haven't actually "sold" the practice for $2 million yet. You have sold it for $1.5 million with a promise of more later if things go perfectly. This creates a psychological weight. You might find yourself still checking the daily appointment book or worrying about a piece of equipment breaking even though you are supposed to be "retired" or moving into a less stressful role. We have seen that the tension of an earnout is often more exhausting than the work of running the practice itself.
Why Do Buyers Push for Earnouts?
It is important to understand that buyers are not necessarily trying to trick you. In the world of optometry and veterinary practice acquisitions buyers use earnouts to bridge the valuation gap. This usually happens when you believe your practice is worth more than what the buyer’s math shows today. They might say they believe in the future of the clinic but they want you to prove it.
Buyers are mostly worried about goodwill. In optometry your reputation and your patient relationships are the most valuable assets you own. A buyer is terrified that the moment you leave 20% of your patients will follow you or simply stop coming because the "doctor they liked" is gone. The earnout is their insurance policy. It ensures that you stay motivated to transition those relationships to the new owner. It is a safety move for them but here is the catch because what protects the buyer often creates a risk for you. If you do not look at the structure carefully you are the one paying for their peace of mind.
The Danger of Metric Manipulation
This is where things get technical and where a lot of owners get burned. An earnout is only as good as the math used to calculate it. Most earnouts are tied to one of two things: Gross Revenue or EBITDA (Net Profit).
If your earnout is tied to Gross Revenue it is generally safer for you. Revenue is hard to hide and hard to manipulate. If the practice brings in $1 million in fees it is $1 million. However many corporate buyers prefer to tie earnouts to EBITDA. This is much riskier for the seller. Once you sell the practice you are no longer the one making the spending decisions. The new owner might decide to hire three more staff members or launch a massive expensive marketing campaign. Those expenses might be great for the long-term health of the clinic but they will lower the net profit in the short term. If your earnout is tied to profit those new expenses could literally eat your retirement money before you ever see it.
We have seen situations where the practice was busier than ever but the owner didn't get their earnings because the buyer’s corporate overhead or new spending wiped out the profit on paper. You have to be incredibly careful about how profit is defined in your contract.
The Problem of Control
The biggest frustration we hear from owners in an earnout period is the loss of control. You are still working in the clinic but you are no longer the boss. If the new owner decides to change the software you hate or stop taking an insurance plan that you know is profitable you might not have the power to stop them. Yet those decisions directly affect whether you hit your earnout targets.
This is why we tell owners that an earnout is essentially a partnership. You are staying in business with the person who just bought you. If you don't trust their management style or their vision for the clinic, staying on for a three-year earnout can feel like being trapped. You are basically betting on your ability to hit someone else's targets while they are the ones holding the steering wheel.
Tax Implications You Cannot Ignore
There is also the tax side of things which most people do not think about until April of the following year. How that earnout is structured in the Purchase Price Allocation changes how much you actually keep. If the earnout is treated as additional purchase price it might qualify for capital gains rates. But if the IRS views it as compensation for future services it could be taxed at much higher ordinary income rates.
Furthermore the timing of these payments matters for your cash flow. If you are receiving payments over one to three years the tax treatment depends on whether installment sale rules apply. If planned carefully you can spread those taxes out as the checks arrive. But if it is not structured correctly you might find yourself owing taxes on the full value of the deal before you have even collected all the money from the buyer. Paying tax on income you have not yet received creates unnecessary pressure at a stage when you are trying to simplify your life.
Entity Structure and State Taxes
Your entity structure (S-Corp, LLC, or C-Corp) also changes how an earnout hits your bank account. In some cases especially with C-corporations there is a risk of double taxation. The corporation pays tax on the gain and then you pay tax again when you take the money out as a distribution and you cannot forget about state taxes. Federal analysis alone is not enough because state income tax adds another layer of cost depending on where your practice is located. A proper review needs to include both federal and state exposure so you understand the full picture. We have seen owners in high-tax states get a shocker of a bill because they didn't realize how their specific state treats deferred earnout payments.
How to Protect Yourself
If you are looking at an offer with an earnout today there are three things you must do to protect your legacy:
Negotiate for Gross Revenue: Whenever possible avoid EBITDA-based earnouts. Tying the money to the top line revenue protects you from the buyer’s spending habits.
Define Exclusions : Ensure the contract states that certain expenses (like the buyer’s corporate travel or legal fees) cannot be charged against your practice’s profit during the earnout period.
Get an Acceleration Clause: This is vital. If the buyer sells the company again or fires you without cause during the earnout period the full amount should become due immediately. You should not lose your money because the buyer changed their mind.
Conclusion
The purchase price is only the starting point because what truly determines your outcome is how the transaction is structured and how the value is allocated. Two practice owners can sell for nearly identical amounts and walk away with very different results simply because one evaluated the earnout and tax implications early and the other focused only on the headline number.
You spent decades building your optometry practice and your exit should reflect that same level of thought. Careful planning ensures that the financial outcome aligns with the years you invested into growing your clinic.
