What it means
Start with EBITDA, which strips out financing costs, tax and non-cash charges to give a rough proxy for operating cash generation. Adjusted EBITDA goes one step further and removes items that are not expected to recur, such as a legal settlement, redundancy costs or the expense of a failed acquisition.
The aim is a number that represents a normal year. The adjustments matter most when a company is being sold, because valuations are frequently expressed as a multiple of adjusted EBITDA.
Adding back $500,000 of genuinely one-off cost at a six times multiple raises the headline price by $3,000,000, which is why buyers scrutinise every add-back line. Owner-managed businesses generate a particular family of adjustments, usually called normalisation.
If the founder pays herself $400,000 where a hired manager would cost $200,000, the excess is added back because the buyer will not carry that cost. The same applies to a partner's car, private travel or rent charged above market rate on a building the owner also owns.
The catch is that adjusted EBITDA is not defined by any accounting standard, so every party calculates it differently. Sellers add back generously, buyers reject items they think will recur, and lenders write their own definition into the loan agreement so that covenant tests cannot be gamed.
Always ask whose definition you are looking at. The most reliable warning sign is a recurring one-off.
A business that has adjusted out restructuring costs in each of the last four years is not removing noise, it is hiding a cost of doing business. A quality of earnings review exists largely to separate the two.
In practice
Real-world examples
Example 1
A founder preparing to sell a distribution business lists $420,000 of add-backs covering her above-market salary, a family member on the payroll and the cost of a discontinued product launch. The buyer accepts the salary and payroll items but rejects the product launch, arguing that a business of that type launches products regularly.
Example 2
A private lender sets a covenant requiring net debt to stay below three times adjusted EBITDA, and writes a closed list of permitted add-backs into the facility agreement. When the borrower tries to add back a warranty provision that is not on the list, the test is calculated without it.
Example 3
A board reviews monthly results where a $180,000 insurance recovery has flattered profit. Management presents adjusted EBITDA excluding the recovery so the directors can see that underlying trading actually softened, and the sales plan is revised accordingly.
Think of it
Adjusted EBITDA is like looking at your car's fuel efficiency on a smooth highway. You remove the temporary drag caused by driving through a sudden mudslide so you can measure how the engine normally performs.
Formula
Calculation
Adjusted EBITDA = net income + interest + tax + depreciation + amortisation + non-recurring or non-operating adjustments.
A specialist packaging company reports net income of $1,200,000, interest of $300,000, tax of $400,000 and depreciation and amortisation of $600,000.
EBITDA = $1,200,000 + $300,000 + $400,000 + $600,000 = $2,500,000.
During the year it also incurred a one-off legal settlement of $250,000, paid the founder $150,000 more than a market-rate managing director would cost, and spent $100,000 relocating a plant.
Total adjustments = $250,000 + $150,000 + $100,000 = $500,000.
Adjusted EBITDA = $2,500,000 + $500,000 = $3,000,000.
At a six times multiple the business is valued on adjusted EBITDA at $18,000,000, against $15,000,000 on unadjusted EBITDA, so the add-backs are worth $3,000,000 of headline price if the buyer accepts them.Case study
Seen in the real world
Merrow Fabrication is an invented company used here as an illustrative example of how add-backs are negotiated. Its owner took the business to market showing adjusted EBITDA of $3,000,000 against reported EBITDA of $2,500,000, expecting a price near six times, or $18,000,000.
The buyer's quality of earnings review accepted the $150,000 owner salary normalisation and the $100,000 plant relocation, both clearly one-off, but challenged the $250,000 legal settlement because Merrow had settled a similar claim in two of the previous four years. On the buyer's view adjusted EBITDA was $2,750,000, and at six times the price fell to $16,500,000.
The parties settled the fictional gap with structure rather than argument. Merrow accepted $16,500,000 at completion plus an earn-out payable if no comparable claim arose within two years. The wider lesson is that an add-back only holds if you can show why the cost will not appear again.
Watch out
Common mistakes
- Treating adjusted EBITDA as cash flow. It ignores working capital movements, capital expenditure, interest and tax, all of which consume real cash before anything reaches the owner.
- Adding back the same cost year after year. A restructuring charge that appears every year is a normal operating cost, and buyers will strip it straight back out.
- Assuming everyone uses the same definition. There is no accounting standard for it, so a lender's covenant definition and a seller's marketing definition can differ by hundreds of thousands of dollars.
Questions
People also ask
Why do buyers care so much about the add-backs?
Because valuations are set as a multiple of the figure, so every dollar of accepted add-back is multiplied several times over in the price.
Is adjusted EBITDA allowed in published accounts?
It is a non-standard measure, so it can be presented alongside statutory figures with a reconciliation, but it cannot replace reported profit in the primary statements.
What evidence supports an add-back?
Contracts, board minutes, invoices and comparable market salary data all help, and an add-back with no documentation is usually the first one a buyer removes.
