Adjusted EBITDA

Formula

Reported, adjusted and pro forma EBITDA

Reported EBITDA is computed from the financial statements. Adjusted EBITDA normalises it for items judged not to represent ongoing performance. Pro forma EBITDA restates the period as if acquisitions made during it had been owned throughout and as if identified cost actions had taken full effect. In leveraged finance the term "covenant EBITDA" refers to the version a credit agreement defines for its financial covenants and debt baskets. These are different numbers for the same company and period, and a leverage or valuation multiple is meaningless until the EBITDA behind it is identified.

Common add-back categories

• Non-recurring items: litigation, restructuring and severance, transaction costs, one-off consulting projects. The test is whether similar costs recur; restructuring that happens every year is a cost of the business.
• Owner and related-party normalisation: owner pay above or below a market-rate replacement, personal expenses, related-party rent or supply at non-market terms. These can reduce EBITDA as well as increase it.
• Stock-based compensation: non-cash and often added back in leveraged finance, although it is an economic cost borne by shareholders through dilution.
• Pro forma acquisitions: pre-ownership earnings of businesses acquired during the period.
• Cost-saving actions taken: the annualised effect of actions already completed, such as headcount reductions or renegotiated contracts, that only partly show in the period.
• Cost-saving actions to be taken and run-rate synergies: expected savings from actions not yet completed, including run-rate synergies from combining acquired businesses. These rest most on judgement and least on evidence.
• Other items: sponsor monitoring fees, non-cash gains and losses, and similar items, depending on the definition.

Why buyers and lenders scrutinise adjustments

Price is commonly set as a multiple of EBITDA (see EV/EBITDA multiple), so each unit of adjustment is worth the multiple in enterprise value. Leverage, interest cover and covenant headroom are measured on the credit agreement's definition, so generous add-backs make the same debt look less risky and leave less real cushion before a maintenance covenant is breached; covenant headroom measured on adjusted EBITDA can overstate how far earnings can fall. Credit agreements commonly cap pro forma cost savings and synergies, as a percentage of EBITDA or a fixed amount, and require the underlying actions to be taken or the savings realised within a set period, often with an officer's certification. Caps, look-forward periods and certification vary widely between agreements and over the credit cycle, and some agreements have no cap. The same definitions drive incurrence covenants and the size of debt baskets.

Testing an add-back

Diligence providers and lenders ask the same questions of each adjustment: Is there documentary evidence for the amount? Has a similar item occurred in prior years? Is the cash cost still being paid? Would a new owner have to incur the cost anyway? For cost savings, has the action been taken, and do monthly results show the run-rate? For acquisitions, are the acquired figures audited or reviewed, and on the same accounting basis? A quality of earnings report records the answers and produces a diligence-adjusted EBITDA alongside management's figure.

Adjusted EBITDA in reporting and valuation

Sponsors report adjusted EBITDA for portfolio companies to LPs and use it in valuation. When a mark is built from comparable-company multiples, the multiple and the EBITDA it is applied to must be defined consistently: applying a peer multiple computed on reported EBITDA to a target's pro forma EBITDA overstates value. In a value bridge, using adjusted EBITDA at exit and reported EBITDA at entry overstates earnings growth. Public companies that present adjusted EBITDA are subject to securities-regulator rules on non-GAAP measures. In the US, a registrant that publicly discloses a non-GAAP financial measure must also present the most directly comparable GAAP measure and a reconciliation between the two (Regulation G, 17 CFR 244.100(a)). In the EU, the European Securities and Markets Authority (ESMA) guidelines on alternative performance measures, which give EBITDA as an example, call for a reconciliation to the most directly reconcilable line item, subtotal or total in the financial statements.

Worked examples

Examples are illustrative; figures are not market data.

Not the same as

• EBITDA: EBITDA is computed from the financial statements; adjusted EBITDA applies judgement-based or contract-defined adjustments to it.
• Quality of Earnings (QoE): The quality of earnings (QoE) report is the diligence analysis that tests management's adjusted EBITDA and produces a diligence-adjusted figure.
• Debt-to-EBITDA (Leverage Multiple): Debt-to-EBITDA is a leverage ratio; its meaning depends on which EBITDA, reported, adjusted or covenant, sits in the denominator.

Common mistakes

• Comparing leverage multiples across deals without checking whether EBITDA is reported, adjusted or pro forma.
• Adding back "non-recurring" costs that recur every year.
• Counting run-rate synergies for actions not yet taken without a time limit or evidence.
• Applying a peer EV/EBITDA multiple computed on reported EBITDA to a target's pro forma EBITDA.
• Adding back the owner's entire compensation rather than the excess over a market-rate replacement.

Edge cases

• Deductions matter as much as add-backs: below-market owner pay, one-off gains and standalone costs in a carve-out all reduce EBITDA.
• Covenant EBITDA can exceed the diligence-adjusted figure, because the credit agreement may permit broader pro forma adjustments than the diligence provider accepted.
• Lease accounting differs between frameworks. Under IFRS 16 a lessee presents depreciation of the right-of-use asset and interest on the lease liability (paragraph 49), both outside EBITDA, except for short-term and low-value leases it elects to expense (paragraphs 5 and 6); under US GAAP an operating lease gives a single lease cost recognised on a generally straight-line basis (ASC 842-20-25-6). EBITDA figures being compared can therefore be before or after lease costs.
