According to the Stanford GSB 2024 Search Fund Study, the median search fund acquisition closes at approximately 7.0x EBITDA. That number only means something if the EBITDA figure it's multiplied against is real. Most of the time, it isn't. Not entirely.
Sellers present adjusted EBITDA: a number that adds back expenses they claim are non-recurring, non-operational, or owner-specific. At the lower middle market, adjusted EBITDA routinely runs 20-50% above reported EBITDA. Every dollar in that gap is real money at closing. On a $5M deal priced at 6.5x, $200,000 of unsupported add-backs equals $1.3M in purchase price you shouldn't be paying.
Your job as the buyer: evaluate each add-back line by line. Some are valid. Some are inflated. Some are fiction. Treating them as a package is how operators overpay.
What an add-back actually is
An add-back is an adjustment to net income intended to show what the business earns for a normalized owner-operator. The logic is straightforward. Small business owners run personal expenses through the company. They pay themselves above or below market. They have one-time costs that distort the trend line. Strip those out, and you see the actual earning power.
That's the valid case. The problem is that add-backs have become negotiating positions. Sellers and their brokers push the number up. Your Quality of Earnings (QoE) firm pushes it back down. The final adjusted EBITDA lands somewhere in the middle. According to BDO's QoE methodology data, a professional QoE review typically identifies 10-30% of claimed add-backs as unsupported or overstated.
Understand the framework before you open the seller's schedule. There are three categories of adjustment.
One: Pro-forma items. Costs the seller says won't repeat post-close because the business or ownership structure will change. Two: Corrections of errors or timing. Accounting adjustments that normalize revenue or expense recognition. Three: Non-recurring transactions. Genuine one-time events that distort the normal run-rate.
Each category has legitimate entries. Each also gets abused.
Add-backs buyers consistently accept
The following twelve categories clear scrutiny in most institutional deals, provided they're properly documented.
1. Excess owner compensation. The single largest add-back in most small business acquisitions. If the owner pays themselves $450,000 in a role that would cost $200,000 to replace with a market-rate CEO, the $250,000 difference is a valid add-back. Reverse this if the owner is dramatically underpaid relative to their function. A founder pulling $80,000 while serving as CEO, head of sales, and de facto CFO may require $300,000 or more in replacement costs. That's a negative adjustment that reduces your EBITDA number.
2. Owner perks. Personal vehicles, country club memberships, personal travel, family health insurance beyond market norms. Document each item with specifics.
3. One-time professional fees. Legal fees for settled litigation, accounting fees for a one-time restatement, consulting fees for a specific project that ended. The key word is "one-time." If the legal expenses are ongoing, they're an operating cost.
4. Related-party rent above market. Owner-occupied real estate leased back to the company at above-market rates. Normalize to the market rate and add back the premium.
5. Family wages above market. Compensation paid to family members beyond what an unrelated employee in the same role would earn.
6. Severance. One-time severance payments to former employees that are documented, complete, and won't recur.
7. M&A transaction costs. Legal, accounting, and advisory fees tied to the current sale process or a prior transaction. These don't represent ongoing business costs.
8. Asset write-downs. Non-cash impairments of inventory or assets with appropriate documentation.
9. Settled litigation. Payments on cases that are fully resolved with no ongoing exposure. Confirm with legal diligence that there are no related claims outstanding.
10. Discontinued operations. A product line, location, or division the seller has formally exited, with supporting documentation showing the exit is complete.
11. Accelerated depreciation. Non-cash D&A charges on operating assets. Accepted in approximately 89% of QoE engagements reviewed under BDO's methodology. Amortization of acquired intangibles from a prior acquisition is different. You will carry that same amortization burden post-close, so treat it carefully.
12. Deferred capex normalization. Capital expenditures the seller has delayed that a new owner will need to make. This one cuts both ways. If the seller has underspent on maintenance, you're buying into a capital call.
Add-backs buyers reject
Three categories fail almost every institutional QoE review.
Future-savings add-backs. Costs the seller claims you will eliminate after acquisition because of your scale, different structure, or anticipated operational changes. Removing the seller's redundant back-office software because you have your own is a future savings event, not a current cost the business is bearing. Your equity upside on that call doesn't belong in the seller's adjusted EBITDA. It belongs on your model's upside case. Future-savings add-backs are consistently rejected by institutional buyers.
Undocumented personal expenses. The seller says there are personal expenses run through the company but can't produce receipts, credit card statements, or accounting classifications. No documentation, no add-back.
Ongoing operational costs presented as one-time. A recurring software subscription the seller used once, marketing spend that drove revenue during the period, or staffing costs for a function that will continue post-close. If the cost recurs in the normal operation of the business, it stays in EBITDA.
Owner compensation: where most deals get complicated
The owner compensation add-back deserves its own treatment because it's the most variable and the most negotiated.
Start with market data, not the seller's claims. Pull comparable compensation benchmarks for the CEO role in the relevant industry and geography. The Economic Research Institute (ERI) Salary Assessor, Radford, and industry association surveys are defensible sources. Get two or three data points. Your QoE firm will do this independently; make sure your number and theirs are in the same range before you present it to the seller.
Model the full role, not just the title. A founder who handles sales, operations, HR, and technology may require three separate hires to replace. Count all of it.
Watch for owners who present their salary as the entire add-back, then separately claim personal expenses. Those two buckets overlap. Vehicles, club memberships, and personal travel that are already in the compensation package shouldn't also appear in the owner perks line. Double-counting is a common mistake in seller-prepared schedules, and it's not always intentional.
Building your position: the bridge table
When you disagree with an add-back, the professional way to handle it is with a documented bridge table. Present: seller-stated EBITDA, each contested add-back with your accept/reject/partial position and the supporting rationale, and your adjusted EBITDA at the bottom.
This does two things. It shows the seller you've done the work, not just an arbitrary price cut. It forces each contested item into a factual dispute, which is solvable with documentation. A seller with a legitimate add-back can produce the documents. A seller who cannot produce documents is asking you to accept an unverified upward adjustment to the price you'll pay at closing.
Bring your QoE firm's written position on each contested item to that conversation. When the dispute is between the buyer's opinion and the QoE firm's independent analysis, the QoE firm's position carries. That's why you hired them.
The QoE as the arbitration layer
A Quality of Earnings report costs $15,000 to $50,000 depending on deal size and complexity. For any deal with $1M or more in seller-claimed EBITDA and add-backs exceeding $100,000, it's the highest-ROI diligence investment you'll make.
Engage the QoE provider immediately after LOI. Don't wait until late-stage diligence. Your senior lender will require a validated EBITDA for underwriting. The final purchase price negotiation will reference the QoE number. Getting it early gives you time to work through disputed items before you're in a compressed timeline with a financing contingency expiring.
For larger deals, consider commissioning a sell-side QoE before going to market if you're on the sell side. Sellers who run sell-side QoE typically face 80% fewer add-back disputes during buyer-side diligence, according to CT Acquisitions transaction data. That typically translates to higher LOI prices and cleaner closings.
The pattern is the same every time
Deal structure in lower middle market acquisitions doesn't change much from target to target. The players change. The industries change. The specific line items change. But the add-back negotiation follows the same pattern: seller presents an inflated number, QoE validates or rejects each line, buyer and seller negotiate on the disputed middle.
Your edge is preparation. Know the 12 categories before you open the seller's schedule. Know which three categories fail every QoE review. Know how to build the bridge table. When you sit down with a seller's adjusted EBITDA, you're not reading a document. You're running a pattern recognition exercise.
EOD operators don't approach an unknown device with optimism. They approach it with methodology. The add-back schedule deserves the same treatment. Identify each component. Assess what's real. Clear the ones that don't belong. Make the call on valuation only after you've done the work.

Frequently Asked Questions
What categories of add-backs do institutional buyers consistently reject?
Three categories fail almost every institutional quality-of-earnings review. Future-savings add-backs claim costs the buyer will eliminate post-acquisition, but those belong in the buyer's upside model, not the seller's adjusted EBITDA. Undocumented personal expenses with no receipts or accounting classifications also get rejected. Ongoing operational costs presented as one-time items are the third category.
What is the owner compensation add-back and why does it require close scrutiny?
The excess owner compensation add-back covers the gap between what the owner pays themselves and what a market-rate replacement CEO would cost. It is the largest add-back in most small business acquisitions. A founder pulling $80,000 while also serving as head of sales and de facto CFO may require $300,000 or more in replacement costs, which is a negative adjustment that reduces EBITDA.
When should a buyer engage a Quality of Earnings firm, and what does it cost?
Engage the QoE provider immediately after LOI, not in late-stage diligence. A QoE report costs $15,000 to $50,000 depending on deal size and complexity. For any deal with $1 million or more in seller-claimed EBITDA and add-backs exceeding $100,000, it is the highest-ROI diligence investment available.
How much of sellers' claimed add-backs does a professional QoE review typically find unsupported?
A professional QoE review typically identifies 10% to 30% of claimed add-backs as unsupported or overstated, according to BDO's QoE methodology data. At the median search fund multiple of approximately 7.0x EBITDA, even modest unsupported add-backs represent significant dollar amounts at closing.
