EBITDA Add-Backs: 6 Rules to Test a Seller's Numbers Before You Pay for Them

In April 2018, WeWork went to the bond market to raise $500 million. Its filings showed a net loss of $933.5 million for 2017. They also showed a number the company called "community adjusted EBITDA": a profit of $233.1 million. To get there, WeWork added back not only interest, taxes, depreciation and amortization, but marketing, general and administrative costs, and design and development spending. Adam Cohen, founder of the research firm Covenant Review, said he had never seen the phrase in his life.

WeWork is the extreme case, but the habit is everywhere. Every seller of a private business arrives with a list of adjustments that turn reported profit into "adjusted EBITDA," and every buyer pays a multiple of whatever number survives. In an acquisition, the add-back schedule is not a footnote: it is the price. At a 6x multiple, every $100,000 of add-backs you accept adds $600,000 to what you pay.

Here are the six rules I use to decide which add-backs are real, and how a quality of earnings review protects the buyer from paying for profits that were never there.

Why add-backs decide the deal

S&P Global Ratings has studied this for years. In its early review of leveraged deals, reported by Institutional Investor in 2018, actual EBITDA came in 29 percent below company projections for 2016 deals and 34 percent below for 2017 deals. Add-backs made up 47 percent of projected EBITDA in leveraged buyouts, and S&P has kept finding that the larger the add-backs at closing, the bigger the miss afterwards.

Lenders pay for this too. A 2022 working paper from the Federal Reserve Bank of St. Louis, by Miguel Faria-e-Castro and co-authors, found that loans whose covenants allowed more EBITDA add-backs were more likely to become delinquent, default or be downgraded.

A buyer who accepts the seller's adjusted EBITDA without testing it is not buying a business: he is buying the seller's opinion of it. I wrote about the warning signs in the nine red flags that should stop a deal. An add-back mountain was number two on that list. This article is how to climb it.

Rule 1: Rebuild EBITDA from the bank statements up

Start with cash, not with the seller's spreadsheet. Match reported revenue to bank deposits month by month, and reported costs to payments out.

• Revenue that does not reach the bank is a question, not a profit: unpaid invoices, related-party sales, or revenue booked early.
• Costs that leave the bank but never reach the income statement often sit on the balance sheet as "prepaid" or "capitalized" items.
• Cash basis versus accrual. Many small companies keep cash books. Convert them to accrual before you compare years, or seasonality will look like growth.

If you cannot tie EBITDA to the bank account, you do not know what you are buying. Everything else in this list depends on this step.

Rule 2: A one-time cost has to happen one time

The most common add-back is the "non-recurring" expense: a lawsuit, a consultant, a system migration, a bad debt. Some are real. The test is simple: look at five years, not one.

If an "exceptional" cost appears in three of the last five years, it is a cost of doing business. A company that has a lawsuit every year has a legal budget. A company that "refurbishes equipment" every year has maintenance capex. Price it in.

Rule 3: Normalize the owner, in both directions

Owner add-backs are legitimate when they are real: a family car, a salary well above market, a relative on payroll who does no work. Sellers rarely mention the other direction.

• An owner paid below market is a hidden cost. If the founder earns $95,000 doing a job you will have to fill at $240,000, EBITDA must go down by the difference.
• Unpaid family labor is the same. In family businesses, a spouse or child often runs the office for nothing. Someone will have to be paid.
• Related-party rent must be reset to market, up or down, and only if you will really pay market rent after closing.

Normalization is symmetric: a seller who adds back the boat must also deduct the salary he never paid himself.

Rule 4: Treat projected savings as a negotiation, not as earnings

"Run-rate" add-backs claim profit that has not happened yet: a price increase announced last month, a supplier contract to be renegotiated, staff cuts planned after closing.

Pay for savings already achieved; negotiate an earn-out for savings promised. If the seller is confident, the earn-out costs him nothing. I explained how to build that bridge in how to structure an acquisition with earn-outs and seller notes.

Rule 5: Check what the add-backs did to working capital and capex

EBITDA can be lifted without any add-back at all. A seller who delays supplier payments, cuts inventory below safe levels or skips maintenance for two years shows a better final year. The bill arrives after you sign.

• Compare days of receivables, payables and inventory across three years. A sudden improvement in the sale year deserves a question.
• Compare capex to depreciation. Years of capex well below depreciation means the assets are aging and you will be paying to catch up.
• Make sure the working capital peg reflects a normal level, not the squeezed one. I covered that in the six rules for the working capital peg.

Profit that was borrowed from the balance sheet has to be repaid by the new owner.

Rule 6: Commission your own quality of earnings, and price on your number

A quality of earnings (QoE) report is an accounting review, usually by an independent firm, that tests whether the earnings are real, recurring and supported by cash. It is not an audit: it does not sign off on the financial statements, it challenges the adjustments.

Practitioner estimates suggest that buy-side reviews commonly reject 10 to 30 percent of the add-backs a seller proposes, according to a 2026 guide from Papermark. For a small or mid-sized deal, a QoE often costs from around $25,000, which is almost always cheaper than one bad add-back multiplied by the price.

Price the deal on the EBITDA your own advisors can defend, then let the seller argue up from there, never down from his. A sell-side QoE from the seller is useful, but it was paid for by the side that wants a higher number.

How we apply it

Across eight business verticals and more than a century of family ownership since 1890, the deals I am happiest about are the ones where we argued hardest over a spreadsheet before we signed. The add-backs we rejected were never a reason to walk away. The ones we accepted without testing were usually the reason a deal disappointed.

Key Takeaways

• The add-back schedule is the price: at 6x, every $100,000 accepted adds $600,000 to what you pay.
• Rebuild EBITDA from the bank statements, not from the seller's adjusted figure.
• A cost that recurs is not one-time: look at five years before accepting "exceptional" items.
• Normalize the owner both ways: below-market pay and unpaid family labor reduce EBITDA.
• Pay for savings achieved, earn out savings promised.
• Watch working capital and capex: a squeezed final year inflates EBITDA.
• Commission your own quality of earnings and price on the number your advisors defend.

Frequently Asked Questions

Does EBITDA include add-backs?

Reported EBITDA does not. Add-backs are adjustments a seller or analyst applies to reported EBITDA to show "adjusted" or "normalized" EBITDA, the figure most private company deals are priced on. That is why every add-back has to be tested: it moves the price directly.

What is an add-back to EBITDA?

An add-back is an expense removed from the income statement because it is considered non-recurring, discretionary or unrelated to the business going forward. Typical examples are one-time legal costs, owner perks, above-market owner salaries and transaction fees. A legitimate add-back is documented, truly non-recurring and will not have to be paid by the new owner.

How do you calculate quality of earnings?

A quality of earnings review starts from reported EBITDA, tests each proposed adjustment against invoices, contracts and bank records, and adds its own adjustments where the seller missed costs. It also reconciles earnings with cash flow and analyzes working capital trends. The result is an adjusted EBITDA that the buyer can defend and price on.

Is a quality of earnings report the same as an audit?

No. An audit gives an opinion on whether the financial statements follow accounting standards. A quality of earnings report asks a different question: whether the earnings are sustainable and what a buyer should pay for. Many audited companies still need a QoE before a sale.

Before You Sign

Take the add-back schedule of the next business you look at and ask one question of every line: would I bet my own money that this cost disappears the day after closing? Every line where the answer is no belongs back in EBITDA.
