EBITDA Adjustments: Which Add-Backs Are Legitimate and Which Will Kill Your Deal

Every business for sale comes with a list of adjustments. The seller — or their broker — has taken the reported EBITDA and added back expenses to make earnings look higher. On paper the business earns $700K. After adjustments, the "adjusted EBITDA" is $1.1M. That $400K difference can move the purchase price by $1–2M.

Some of those adjustments are legitimate. Some are not. The problem is that sellers and buyers rarely agree on which is which — and the quality of earnings process is where it gets sorted out.

What EBITDA Adjustments Are and Why They Exist

EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortization) is the most common valuation metric for businesses in the $1M–$30M range. Multiply EBITDA by 3x, 4x, or 5x and you have a purchase price.

The problem: the EBITDA reported on a seller's P&L is almost never the right number to use. Owner-operated businesses run personal expenses through the company, pay the owner non-market compensation, and have one-time items that inflate or deflate earnings in any given year.

EBITDA adjustments — also called add-backs or normalizations — are changes made to reported EBITDA to better reflect what the business actually earns under normal conditions, going forward, under new ownership.

A legitimately adjusted EBITDA answers: what would this business earn if it were run by a professional owner-operator, excluding one-time events?

That number is what drives valuation. And it's what a quality of earnings report is designed to verify.

The Four Main Categories of EBITDA Adjustments

1. Owner Compensation Normalization

This is the most common adjustment and usually the largest.

Most business owners don't pay themselves a market-rate salary. Some pay themselves too much — running their lifestyle through payroll. Some pay themselves too little to minimize taxes. Either way, the reported compensation doesn't represent what the role actually costs a new owner.

The adjustment: replace the owner's actual total compensation with what a market-rate replacement would earn.

Real example: A $4.5M revenue HVAC company where the owner takes a $480K salary. A qualified GM to replace the operational function would cost $130K–$160K. The add-back is $320K–$350K — which changes the valuation by nearly $1M at a 3x multiple.

This adjustment almost always holds up. The debate is whether the replacement cost is accurate. If the owner runs all customer relationships, handles estimating, and manages the crew — a $130K GM doesn't cover the full replacement cost. A proper adjustment accounts for every function the owner performs.

2. Personal Expenses Run Through the Business

Owner-operated businesses routinely run personal expenses through the company: personal vehicles, family meals, travel, cell phones, health insurance, club memberships, home office expenses.

These are add-backs when they represent genuine personal consumption with no business purpose.

Real example: A distribution company with $52K/year in vehicle expenses. After reviewing the underlying schedules, two of the three vehicles on the books are personal — a pickup truck used mostly for personal trips and a leased SUV in the owner's wife's name. Add-back: $38K. The remaining $14K covers a delivery van with legitimate business use.

What buyers get wrong: accepting the add-back without documentation. A QoE provider should pull supporting schedules, verify against bank statements, and confirm which expenses are genuinely personal. "The broker says it's personal" is not an analysis.

3. One-Time and Non-Recurring Items

These are expenses (or income) that occurred in the historical period but won't happen again under new ownership.

Legitimate one-time add-backs: - Legal fees from a specific, resolved dispute - Moving costs from a one-time facility relocation - Costs from a system implementation now complete - Severance for an employee whose position was eliminated

Questionable "one-time" add-backs: - Legal fees for a business with litigation every year — just different cases - Equipment repairs described as non-recurring on a building with years of deferred maintenance - Marketing spend labeled non-recurring with no explanation of why it won't recur - "COVID impact" revenue adjustments without contracted evidence to support them

The test: can you point to a specific, documented event — and is there a clear reason it won't happen again? If the answer requires speculation, the add-back shouldn't hold.

4. Run-Rate Adjustments for Known Changes

These are adjustments for changes that have already happened but aren't yet fully reflected in the trailing twelve months.

A new hire started six months ago at $90K/year. The TTM P&L only shows six months of that salary. A run-rate adjustment adds the missing six months of expense — which reduces normalized EBITDA, not increases it.

A seller just moved to a cheaper facility. Rent dropped from $14K/month to $9K/month three months ago. The run-rate adjustment removes the old, higher rent from the normalized view.

These adjustments cut both ways. A QoE provider should look for run-rate changes that hurt normalized earnings just as carefully as they look for ones that help.

How EBITDA Adjustments Get Abused

Sellers and brokers have every incentive to maximize the add-back list. Some adjustments are legitimate. Some are not. Here's where deals most often break down.

Double-counting owner compensation. The owner takes a $260K salary, $120K in distributions, and $55K in personal vehicle expenses. The broker normalizes the salary to $120K, but also adds back the distributions and vehicles separately. Some of this overlaps — total owner compensation should be assessed as a whole, not as three independent line items.

"One-time" expenses that appear every year. We see this regularly. Add-back of $35K in legal fees described as one-time. Three years of bank statements show legal expenses every year, just for different matters. That pattern isn't one-time — it's a recurring cost of doing business.

Add-backs that defer real costs. A company adds back $80K in equipment maintenance as "non-recurring capital." But the equipment hasn't been serviced in three years and the deferred maintenance becomes the buyer's problem at close. You'll spend it. It just won't appear in the diligence period.

Revenue add-backs with no documentation. "We would have earned $300K more if not for the supply chain disruption." Without a signed contract or a specific, verifiable customer opportunity, this is a forecast dressed up as an adjustment.

What a QoE Does to the Add-Back List

A proper quality of earnings analysis doesn't accept the seller's adjustments — it builds its own from scratch.

That means pulling the P&L and bank statements and identifying every material expense line, asking for documentation on every add-back claimed, testing revenue against deposits to catch recognition issues, and building a normalized EBITDA schedule where every line is supported.

What to Do Before Your Deal Closes

1. Get the seller's add-back schedule before you go under LOI. Every broker's package includes adjustments. Ask for a detailed schedule with documentation for each line item before you submit an offer. 2. Request 24–36 months of bank statements. This is the ground truth. Don't accept a P&L without bank statements to cross-reference. 3. Flag anything described as "one-time" without a specific, documented event behind it. 4. Engage a QoE provider early. The QoE findings inform the working capital peg, the purchase price, and the reps and warranties. Waiting until after the purchase agreement is signed means you've lost your leverage to renegotiate.

Bedrock runs buy-side QoE engagements for deals in the $1M–$40M range. Typical turnaround is 2–4 weeks. Talk to us before you go under LOI.
