How to Normalize EBITDA Across Disclosed Precedent Transactions

A precedent multiple means something only if the EBITDA in the denominator is measured the same way as the EBITDA of every other transaction in the set. In practice it almost never is. Two deals in the same sector, same year, and same size band can produce materially different multiples because one used as-reported EBITDA and the other used an adjusted figure that stripped out restructuring charges, owner compensation above market, and operating lease costs capitalized under the accounting standard that applied to that deal.

Normalization is the process of making those EBITDA figures comparable. It is not a creative exercise — it is a discipline of reading disclosures carefully, applying adjustments consistently, and recording what was changed and why. An analyst who normalizes selectively, applying favorable adjustments to some transactions and not others, produces a range that will not survive challenge.

What “adjusted EBITDA” means in practice

EBITDA is not a term defined by GAAP or IFRS. It is a practitioner shorthand for earnings before interest, taxes, depreciation, and amortization — derived from a company’s income statement but not the same as any line on it. Because it is not standardized, every company and every deal party can calculate it differently.

A disclosed “adjusted EBITDA” in a press release or fairness opinion adds a further layer: the reporting party has removed items they judge to be non-representative of the business’s ongoing earnings capacity. The SEC’s non-GAAP guidance requires that publicly traded companies explain and reconcile every adjustment in their disclosures; those reconciliation tables are the starting point for understanding what the reported EBITDA figure actually contains.

For a precedent set, the normalization question has two parts. First: what adjustments, if any, did the deal parties apply to the target’s EBITDA to arrive at the multiple stated in the announcement? Second: are those adjustments consistent with what you applied to every other transaction in the set? If the answers are different, you have not built a comparable set.

The most common adjustments

Non-recurring items

Non-recurring items are the most frequently disclosed category of EBITDA adjustment. They include restructuring and reorganization charges, legal settlements and litigation costs, executive severance, impairment losses, one-time transaction bonuses, and gains or losses on asset disposals.

The principle for including or excluding a non-recurring item is whether it is representative of the business’s normalized earnings power. A restructuring charge that occurred once in the last five years is a reasonable candidate for exclusion. A company that reports “restructuring charges” in every period is, by definition, running a business that includes restructuring as an ongoing cost — and that cost belongs in the EBITDA used to set the multiple.

When a press release or proxy statement discloses the adjustment, record it. When it does not, do not infer it. An undisclosed adjustment is not comparable to a disclosed one, and including it without documentation makes your set harder to defend than if you had used the as-reported figure throughout.

Owner and management compensation adjustments

Private company targets frequently have owner compensation that differs materially from what a professional management team would be paid. A founder drawing below-market salary produces EBITDA that overstates normalized earnings once the company changes hands. A founder drawing above-market salary has the opposite effect.

These adjustments matter most for privately held or owner-managed targets, which appear in many precedent sets for mid-market and small-cap transactions. The adjustment is conceptually straightforward — replace the disclosed compensation with a market-rate estimate — but in practice it requires knowing both the founder’s actual compensation (not always disclosed) and what market rate for that role looks like in that geography and sector. When a fairness opinion discloses an owner-compensation adjustment, use it. When neither the company nor the transaction documents disclose founder compensation, the adjustment cannot be made from public sources, and you should record that the EBITDA is as reported rather than normalized for owner compensation.

IFRS 3 and its US GAAP equivalent require that acquisition-related costs — advisory fees, legal fees, due diligence expenses — be expensed in the period incurred rather than capitalized into the deal price. That means a company being sold will often report elevated SG&A in the period of the transaction as these costs flow through the income statement.

For a target’s LTM EBITDA calculated from the period ending at or near announcement, deal costs may be depressing the reported figure. Whether to add them back depends on disclosure: if the fairness opinion or press release explicitly identifies deal costs in a reconciliation, add them back consistently across the set. If they are not itemized, you may not be able to distinguish them from other SG&A movements without access to detailed management accounts.

Lease treatment under IFRS 16 and ASC 842

This is the least visible but often most significant source of EBITDA inconsistency across a precedent set that spans deals before and after 2019.

IFRS 16 (effective for periods beginning January 1, 2019) and ASC 842 (effective for most US public companies in fiscal years beginning December 15, 2018) require that operating leases be capitalized on the balance sheet. The practical effect on EBITDA: lease payments that were previously recorded as an operating expense (reducing EBITDA) are now split into a depreciation component (excluded from EBITDA) and an interest component (excluded from EBITDA). For a company with significant lease obligations — retail, logistics, healthcare facilities, restaurant chains — the EBITDA boost from this reclassification can be material, often 10–30% for lease-intensive businesses.

A precedent set that includes deals before and after this accounting change will mix two different EBITDA definitions unless you adjust for it. The options are:

Restate pre-standard EBITDA to include the lease capitalization effect. For each pre-2019 deal, identify the disclosed operating lease commitments, estimate the on-balance-sheet right-of-use asset and liability using an appropriate discount rate, and remove the operating lease payment from operating expenses. This is technically correct but requires detailed disclosure that may not be available for every target.

Restate post-standard EBITDA to exclude the lease capitalization benefit. Add the implied depreciation-equivalent of the lease back into EBITDA for post-2019 deals, effectively reverting to the pre-standard treatment. Some data terminals now label this as “EBITDAR” (earnings before interest, taxes, depreciation, amortization, and rent) and calculate it consistently across periods.

Flag the standard transition in your table. If adjustment is not practical, label each transaction with the applicable accounting standard period and note the potential magnitude of the difference. A reader can then apply their own judgment about how much weight to place on cross-period comparisons. What you cannot do is present a pre-2019 multiple and a post-2019 multiple as comparable without acknowledging the accounting difference.

Pro-forma adjustments for acquired revenues and cost savings

A target that completed an acquisition of its own shortly before the deal announcement may report LTM EBITDA that does not yet reflect a full year of contribution from the acquired business. Deal parties frequently present a “pro-forma” or “run-rate” EBITDA that annualizes the acquired operations, sometimes combined with estimated cost synergies.

Pro-forma adjustments are legitimate for understanding the economics of the combination, but they introduce estimation risk: the annualized revenue projection may not reflect integration costs, customer attrition, or execution risk. For your precedent set, record whether the EBITDA used in the multiple is the target’s standalone reported figure or a pro-forma number, and whether that pro-forma figure is disclosed in the deal documents or is the analyst’s own estimate. Do not substitute a pro-forma EBITDA for a reported one without disclosing the substitution.

How to find disclosed adjustments

The most reliable sources for normalized EBITDA disclosures are:

Press releases and earnings materials. A deal announcement that cites a specific EBITDA figure often reconciles it in an appendix or separate table. This is especially common for US transactions where the SEC requires non-GAAP reconciliations in press releases filed on Form 8-K. Read the full filing, not just the headline paragraph.

Proxy statements and fairness opinions (Schedule 14A or equivalent). The financial analysis section of a proxy will identify the financial metrics used by the acquirer’s and target’s advisers. When an investment bank presents precedent transactions in its fairness opinion, it will typically footnote which EBITDA figure it used and whether adjustments were applied. This is the most reliable source for understanding how practitioners who negotiated the deal defined the denominator.

Tender offer documents and scheme documents. UK scheme documents, Australian scheme implementation deeds, and US tender offer documents filed on Schedule TO often contain a detailed financial analysis from the independent expert or the board’s financial adviser that specifies the adjusted EBITDA used to arrive at the stated multiple.

Regulatory filings. For US public companies, annual reports on Form 10-K and quarterly reports on Form 10-Q contain EBITDA reconciliation tables in the earnings management discussion sections for companies that regularly report adjusted EBITDA as a performance metric. These filings are the source of truth for multi-period EBITDA calculations.

When none of these sources discloses the specific adjustments applied, you are working with an unverified multiple. Record it as such: “Multiple as stated in announcement; adjustment basis not disclosed.” That note does not disqualify the transaction from the set, but it tells the reader what level of verification was possible.

Applying adjustments consistently

The principle of consistency is more important than the specific adjustments you choose. A set where every transaction uses as-reported EBITDA is more defensible than a set where some transactions use adjusted EBITDA and others use reported EBITDA without clear labeling.

Before constructing your set, decide your normalization policy:

Will you use reported EBITDA, adjusted EBITDA where disclosed, or calculate your own adjustments?
How will you handle the IFRS 16 / ASC 842 transition for cross-period sets?
Will you adjust for owner compensation for private targets? If so, what market-rate benchmark?
How will you handle transactions where the adjustment basis is not disclosed?

Document those decisions at the top of the analysis. A counterparty can then argue with your policy rather than searching for inconsistency in the numbers, which produces a narrower and more productive disagreement.

What to record for each transaction

For every EBITDA figure in a precedent set, your records should capture:

the EBITDA in absolute terms and currency, with the financial period end date;
whether the figure is as reported in financial statements or adjusted, and if adjusted, what was adjusted and by how much;
whether the adjusted figure was disclosed by the deal parties or calculated by the analyst;
the source of the figure (press release, proxy, fairness opinion, annual report, calculated);
the accounting standard applicable to the period (pre/post IFRS 16 / ASC 842 for lease-intensive sectors);
any pro-forma adjustment for acquired revenues, and whether that adjustment was disclosed or estimated.

This documentation makes the set auditable. It also means that if a reviewer challenges a specific multiple, you can produce the source document and walk through the arithmetic. That is a tractable discussion. An undocumented adjustment that someone disputes has no resolution path.
