Add-backs: where deals are won and lost.
The multiple gets the attention. The earnings figure it multiplies is where the real negotiation happens.

From Reported EBITDA to Adjusted EBITDA
Normalization estimates sustainable earnings. It does not maximize a number.
$2.0M
Reported EBITDA
+$150K
Nonrecurring legal expense
+$200K
Excess owner compensation
+$100K
One-time facility move
−$50K
Nonrecurring insurance recovery
−$200K
Required replacement management cost
$2.2M
Indicative adjusted EBITDA
$2.0M + $150K + $200K + $100K − $50K − $200K = $2.2M
Potentially supportable
- Clearly nonrecurring
- Documented
- Directly identifiable
- Consistent with how the buyer will operate
Frequently challenged
- Vague one-time costs
- Recurring expenses relabeled
- Unsupported synergies
- Deferred maintenance
- Missing replacement costs
Every adjustment should be documented. Buyers may reject some or all proposed add-backs.
Figures are illustrative. A quality of earnings review applies professional standards and specific procedures that this summary does not replicate.
Reported earnings describe the business as the owner chose to run it. Adjusted earnings describe the business as a buyer would own it. Normalization is the disciplined path between the two, and every dollar of accepted adjustment is worth several dollars of price at typical multiples. That arithmetic is exactly why buyers scrutinize add-backs so hard.
What generally survives diligence
Owner compensation above a market wage for the role, clearly personal expenses run through the business, true one-time items with paper behind them (a lawsuit settled, a flood repaired, a one-off consulting project), and rent adjustments where the owner also owns the building and charges above or below market. The pattern: specific, documented, and genuinely non-recurring.
What gets rejected
Vague categories like miscellaneous or other. Recurring expenses relabeled as one-time for the third consecutive year. Growth spending recast as an add-back, as if the future revenue arrives free. Owner compensation added back entirely when someone still has to do the owner’s job. And optimistic pro-forma synergies presented as if they were history.
The credibility effect
Add-backs are also a signaling exercise. A tight schedule of five documented adjustments makes a buyer comfortable. A list of twenty aggressive ones invites a quality-of-earnings review that reprices the whole deal, because once one adjustment collapses, every number gets a second look. It is usually better to present fewer, stronger adjustments and hold marginal ones in reserve.
Prepare it before someone else does
In any process of consequence, the buyer commissions a quality-of-earnings report. Sellers who build their own normalization schedule first, with documentation attached, control the conversation. Sellers who improvise add-backs in a data room watch their EBITDA get negotiated downward in real time.
Before the buyer’s accountants
A seller-side earnings review changes the process
Normalizing earnings before going to market is among the highest-return preparation work a seller can do.
