Business value comes down to two inputs: adjusted EBITDA and a multiple. Owners tend to focus on the multiple, since the business and its industry are what fuel it.
What matters more in an actual transaction is adjusted EBITDA, and how that number holds up under scrutiny during a quality of earnings analysis.
At a basic level, EBITDA, or earnings before interest, taxes, depreciation, and amortization, is meant to reflect operating profitability. But in practice, standard EBITDA is rarely the number a deal is based on.
Instead, deals are valued on normalized EBITDA, after a full financial analysis identifies what the business actually earns on a sustainable basis. Adjusted EBITDA is a proxy for baseline cash flow, and it is the one starting point every buyer applies regardless of company or industry.
That’s where a quality of earnings report becomes critical. It turns reported financial performance into something buyers and investors can rely on. QoE doesn’t just confirm earnings. In many deals, it changes what the business is believed to earn in the first place. And once that number changes, valuation follows.
Why Adjusted EBITDA Drives Valuation
Most transactions are priced using an EBITDA multiple or broader valuation multiple.
That means enterprise value is directly tied to adjusted earnings, not raw financial statements.
The process looks simple:
Adjusted EBITDA × multiple = valuation
But in reality, each part of that equation depends on interpretation.
The same business can produce different outcomes depending on how earnings are normalized, which is why business valuation is heavily influenced by the adjustments identified during QoE.
How QoE Changes EBITDA (and the Deal)
A QoE analysis reshapes numbers. Typical EBITDA adjustments include:
- removing non-recurring expenses like litigation expenses or one-time legal fees
- normalizing owner compensation and personal expenses run through the business
- adjusting related-party arrangements to market, most often rent paid to an entity the owner controls or services provided by an affiliate
- reflecting run-rate and pro forma effects such as a completed acquisition, a signed price increase, or a headcount change made partway through the period
- removing non-cash charges that sit inside operating expenses, such as impairments, write-offs, and straight-line rent adjustments
- correcting accounting basis issues such as cash-to-accrual conversion, revenue cutoff, and reserve adequacy, which can move EBITDA more than any other category in middle-market deals
These are often referred to as add-backs, but not all add-backs are accepted equally.
The result is a clearer view of:
- true operating performance
- underlying financial health
- sustainable earnings power
This is where many owners first see a gap between perceived and actual earnings.
Small Changes to EBITDA Create Large Changes in Value
Once adjustments start changing EBITDA, they change the entire negotiation.
For example:
- A $300K increase in adjusted EBITDA at a 6x multiple → increases valuation by $1.8M
- A $300K decrease → removes $1.8M from the deal
That’s why even routine adjustments can have outsized impact.
This is also where many businesses lose value before they even get to negotiation. Patterns like aggressive add-backs or weak accounting policies often show up under scrutiny.
Why Buyers and Sellers Interpret Adjustments Differently
Adjustments aren’t just technical. Sellers are trying to defend earnings. Buyers are trying to discount them. The final EBITDA number is usually somewhere in between.
From a sell-side perspective
Adjustments are used to:
- reflect the true earning power of the business
- remove costs that won’t continue
- present normalized EBITDA as strongly as possible
From a buy-side perspective
Adjustments are evaluated to:
- confirm sustainability
- reduce risk
- challenge assumptions that may inflate value
That’s where tension builds.
The same adjustment can be read two ways depending on which side of the table you sit on, whether it is tied to operating expenses, owner discretionary spend, or the timing of revenue recognition.
Where Deals Are Actually Negotiated
Most people assume negotiation happens at the multiple when, in reality, it usually happens at the earnings level first.
Buyers are less concerned with debating whether a company is worth a 5x or 6x EBITDA multiple if they don’t trust the underlying number.
Instead, they:
- reduce or reject add-backs
- question assumptions in the EBITDA calculation
- dig deeper into financial reporting
By the time you get to final valuation, the number has already moved.
This is often where issues that impact business value surface in real time, not because they weren’t there, but because they weren’t identified early.
EBITDA Is Not the Only Place Value Moves
Adjusted EBITDA sets the headline price. Two other diligence findings change what actually gets wired at closing, and sellers rarely see either one coming.
The first is the net working capital peg. Buyers set a target based on a trailing average, and any shortfall against that target comes out of proceeds dollar for dollar. A seller who has been managing cash by stretching payables through the sale process funds that behavior back at closing.
The second is debt-like items. Accrued vacation, deferred revenue, unpaid bonuses, deferred maintenance, and unfunded obligations get treated as debt and reduce equity value. None of them appear on a debt schedule.
A deal can absorb a downward EBITDA adjustment. Losing at the peg and on debt-like items at the same time is harder, because both land after the multiple has already been agreed.
The Compounding Effect of Multiple Adjustments
One adjustment rarely determines the outcome of a deal. It’s the accumulation that matters.
When multiple adjustments stack:
- earnings shift
- confidence shifts
- perceived financial health shifts
And in many cases:
- buyer confidence declines
- diligence expands
- deal timelines extend
Count alone is not the signal. A well-run business can carry eight documented adjustments and clear diligence without friction. A business with two aggressive owner add-backs and an unexplained revenue cutoff will not. What buyers weigh is size relative to reported EBITDA, how well each adjustment is supported, and whether the pattern suggests the accounting was managed toward a number.
This is especially true when financial analysts or investment bankers start probing deeper into inconsistencies across reporting periods.
What starts as a technical adjustment often becomes a credibility issue.
Why Preparation Drives Value More Than Adjustments
By the time a seller enters diligence, most historical numbers are already set. At that point, the focus shifts from fixing to explaining. By preparing early:
- policies align with industry standards
- normalization is clear and documented
- financial performance tells a consistent story
If not, sellers are forced to defend numbers under pressure.
The seller who prepares well is not the one with the cleanest add-back schedule. It is the one who can explain every number without reaching for a file. Buyers discount what they cannot follow, and the discount is always larger than the adjustment would have been.
Understanding what can still be improved, and what cannot, is a critical part of that process.
The Bottom Line: Earnings Determine Everything
At the end of the process, valuation comes down to a two-part question:
What does this business actually earn, and will that continue?
QoE is how to get to the answer.
Once adjusted EBITDA changes, everything else follows:
- valuation
- deal structure
- negotiation leverage
If you don’t understand how adjusted EBITDA impacts your earnings going in, you’re going to figure it out during diligence, and that is usually when value starts to come off (or deals fall apart).
Final Thoughts
Having sat on both sides of this, running a company toward a sale and then running diligence on companies like it, the pattern holds. Owners consistently overestimate how well their numbers explain themselves.
You can understand how this works, but until you see how your own numbers hold up under diligence, you don’t really know what you have. Talk with our Transaction Advisory team about your QoE readiness by scheduling a call below.
