What is adjusted EBITDA?

Adjusted EBITDA is reported EBITDA recast to reflect what the business sustainably earns under normal ownership. It starts from EBITDA and applies a set of adjustments — add-backs for costs that won't recur, and deductions for costs the business has been under-spending on — to arrive at a normalized run-rate figure.

The purpose is to strip out distortions that don't reflect ongoing operations: a one-time legal settlement, the founder's above-market salary, severance from a restructuring, transaction fees, a discontinued product line. A buyer doesn't want to pay a multiple on earnings that were depressed or inflated by items they'll never see again.

Because private companies are typically priced as a multiple of adjusted EBITDA, this is frequently the single most negotiated number in a deal. Unlike statutory EBITDA, adjusted EBITDA is not defined by accounting standards — every adjustment is a judgment call, and each one is contested by the other side of the table.

How adjusted EBITDA is built

The construction runs through a bridge from reported earnings to a defensible run-rate.

  1. Start from EBITDA. Operating income plus depreciation and amortization, before any normalization.
  2. Add back non-recurring items. Genuinely one-time costs — litigation, restructuring, transaction expenses — that won't repeat under the new owner.
  3. Normalize owner-specific items. Adjust above- or below-market owner compensation, related-party rent, and personal expenses run through the business to an arm's-length level.
  4. Apply pro-forma and run-rate effects. The annualized impact of recent price changes, contract wins or losses, and acquisitions, so the figure reflects the go-forward business.
  5. Subtract understated costs. Add back the cost of investments the company has deferred — the deductions that a rigorous analysis insists on, not just the favorable add-backs.

Where adjusted EBITDA gets abused

Because there is no rulebook, adjusted EBITDA is the easiest figure in a deal to inflate. Sellers have an incentive to classify recurring costs as "one-time," to add back aggressive synergies, or to annualize the best quarter rather than a representative period.

This is precisely why buyers commission a quality-of-earnings study to test each add-back line by line. A credible adjusted EBITDA is one where every adjustment can be defended with evidence — and where the deductions for under-spending are taken as seriously as the add-backs. The gap between a seller's adjusted EBITDA and a buyer's is often where the price negotiation actually happens.

Frequently asked.

5 questions
01 What's the difference between EBITDA and adjusted EBITDA?

EBITDA is a defined calculation: earnings before interest, taxes, depreciation, and amortization. Adjusted EBITDA layers discretionary normalizations on top — add-backs for non-recurring and owner-specific items — to estimate sustainable run-rate earnings.

EBITDA is mechanical; adjusted EBITDA is a set of judgments, which is why it is negotiated rather than simply computed.

02 Why are add-backs controversial?

Because each one increases EBITDA, and price is a multiple of EBITDA. A seller has every incentive to characterize recurring costs as one-time. Buyers push back through quality-of-earnings diligence, scrutinizing whether each add-back is genuinely non-recurring.

The contest matters: at a 10x multiple, every dollar of accepted add-back adds ten dollars to enterprise value.

03 Are there standard rules for adjusted EBITDA?

No. Adjusted EBITDA is a non-GAAP measure with no prescribed definition, which is exactly why two parties can produce very different figures for the same company. Credibility comes from documentation — each adjustment supported by evidence — not from a standard.

04 Is adjusted EBITDA the same as pro-forma EBITDA?

They overlap heavily and the terms are often used interchangeably. "Pro-forma" emphasizes run-rate and acquisition effects — what the combined or annualized business would have earned — while "adjusted" emphasizes normalizing add-backs. In practice a full adjusted EBITDA bridge usually includes pro-forma elements.

05 Does the add-back schedule survive after close?

It should, but too often it doesn't. The adjusted EBITDA bridge defines the earnings the price was built on, yet once the deal closes the schedule frequently disappears into a static file, leaving the new owner unable to test whether the normalized number is actually holding.

Keeping the add-back schedule live and reconciled against post-close actuals — so each assumed adjustment can be checked against reality — is part of what VectorShift preserves after the data room shuts down.
