Due Diligence
EBITDA Add-Backs: Which Ones Hold Up in Diligence?
By Will McCurdy, CPA · April 7, 2026 · 5 min read
Seller hands me a schedule of EBITDA add-backs totaling $385K. That bumps adjusted EBITDA from $480K to $820K.
"These are all legitimate," the broker says.
I pull the general ledger. Start checking line by line. Two hours later, $265K of those add-backs are gone. At a 4x multiple, that's $1.06 million off the purchase price.
The broker stops returning my calls for a few days after that.
Add-backs exist in every deal. The question is whether each one is real, recurring, and defensible. Your lender will test them. Your QoE provider will test them. And if you skip that step, your bank account will test them for you.
What an add-back is
An expense the seller incurred that a new owner won't. Added back to earnings because it doesn't represent the ongoing cost of running the business.
Legitimate: The seller paid his wife $80K as an office manager. She didn't work there. That's an add-back. You won't have that expense.
Not legitimate: The seller spent $120K on marketing and calls it "discretionary." Revenue dropped 15% the year they cut it. That's not discretionary. That's the cost of maintaining revenue.
The difference between those two is $200K in purchase price at a 4x multiple.
Add-backs that hold up
Owner compensation above market
Owner pays himself $350K. A replacement GM costs $150K. The $200K difference is a legitimate add-back. Most common and least controversial adjustment.
The catch: you need a defensible market comp for the replacement salary. "I'll just work harder" isn't a comp. Your lender wants to see what it costs to hire someone.
Personal expenses through the business
Country club memberships. Personal vehicles. Family cell phone plans. Owner's health insurance. Personal travel coded as business travel.
Real add-backs if they're personal and go away with the seller.
The catch: they need documentation. "The seller told us $30K was personal travel" isn't enough. The QoE provider will pull credit card statements and categorize each expense.
One-time legal or professional fees
A lawsuit settlement. A one-time consulting project. Legal fees for the owner's divorce that ran through the business. These won't recur.
The catch: "one-time" is the most abused phrase in deal-making. If the business had one-time expenses three years running, they're not one-time. They're a pattern.
Rent above or below market
Seller owns the building and charges the business $8K/month. Market rate is $5K. The $3K/month difference ($36K/year) is an add-back because you'll negotiate a market-rate lease.
This cuts both ways. If the seller charges below-market rent and the lease doesn't transfer, your costs go UP post-close.
Add-backs that don't survive
"Discretionary" marketing
Seller spent $150K on marketing and calls it optional. But the business is a home services company where every lead comes from Google Ads.
Cut the marketing and revenue falls off a cliff.
We see this often. If the expense is required to maintain revenue, it's not an add-back.
Deferred maintenance and capex
Seller hasn't replaced equipment in five years. Adding back depreciation on assets that are past their useful life. But those assets need replacement. That's your problem now.
This isn't an add-back. It's a hidden liability. The QoE should flag deferred capex.
"Non-recurring" revenue dips
Revenue dropped $200K due to "COVID" or "supply chain" or "one bad quarter." The seller adds it back as if normal revenue is $200K higher.
You can't add back revenue that didn't happen. If the business recovered, the trailing twelve months show it. If it didn't, the seller is inflating earnings.
Understaffing
Seller ran the business with three people. A properly staffed operation needs five. That missing payroll cost never hit the P&L, so EBITDA looks better than it should. In your model, you need to burden for two additional hires.
Related party transactions at off-market rates
Seller's brother provides materials "at cost." Sister-in-law does the bookkeeping for free.
A proper QoE normalizes these to market rates. That means adjusting EBITDA downward, not upward. It's a hidden cost, not a savings. You'll pay market rate for both.
How to evaluate any add-back
Three questions. Every time.
Is it documented? Not "the seller told us." Receipts, invoices, bank statements, tax returns. If it can't be traced to a document, it doesn't survive diligence.
Does it go away? The seller's car payment goes away. The marketing spend that generates leads does not. Think about what happens to revenue if you remove the expense.
Is it one-time or a pattern? One lawsuit in five years is one-time. Legal fees every year is a cost of doing business. Look at the full history, not just the trailing twelve months.
What the QoE does with add-backs
A Quality of Earnings report doesn't take the seller's schedule at face value. It:
Reconstructs adjusted EBITDA from the general ledger, bank statements, and tax returns.
Tests each claimed add-back against supporting documentation.
Identifies add-backs the seller missed. Both positive (expenses that should be added back) and negative (hidden costs the seller left out).
Builds the adjustment bridge showing reported to adjusted earnings with every line item explained.
The result is a defensible EBITDA number your lender will accept, your attorney will rely on, and you can use to negotiate.
The dollar impact
Here's a pattern we see all the time:
Seller's Add-Back — Amount — QoE Finding
Owner salary — $180K — Market comp supports $150K replacement. $30K adjustment.
Wife on payroll (no-show) — $75K — Confirmed
"One-time" marketing campaign — $60K — Rejected. Similar spend every year
"Discretionary" travel — $40K — $15K personal, $25K business development. Adjustment is $15K
Deferred equipment replacement — $30K — Rejected. Buyer will need to spend this
Seller's total add-backs — $385K
QoE-confirmed add-backs — $120K
Gap — $265K
At a 4x multiple, that $265K gap is $1.06 million in purchase price. That's what the QoE saves you.
Before you sign
Don't accept the seller's add-back schedule as fact. It's a starting position, not a conclusion.
Get a QoE. The cost of a QoE report is a fraction of one bad add-back at a 4x multiple.
Negotiate off the adjusted number. The QoE gives you the evidence to renegotiate. Not from emotion. From documentation.
