This is general information, not investment advice.
You'll see "EBITDA" in nearly every earnings release. It's worth knowing what it reveals — and what it hides.
What it stands for
EBITDA = Earnings Before Interest, Taxes, Depreciation, and Amortization. In plain terms: what a company earns from its core operations before the effects of how it's financed, where it's taxed, and how accountants spread asset costs over time. The Corporate Finance Institute describes it as a gauge of "core profitability from operations."
How it's calculated
Two routes to the same number: start from net income and add back interest, taxes, depreciation and amortization; or take operating income and add back depreciation and amortization. The idea is to isolate the cash-generating engine before financing and accounting choices.
What each add-back removes
- Interest — the cost of debt; stripping it out compares firms as if they had the same capital structure.
- Taxes — vary by country and circumstance; removing them aids cross-border comparison.
- Depreciation — an accounting charge that spreads the cost of a physical asset (a factory, trucks) over its life. No cash leaves the door in the year it's booked, but it reduces reported profit.
- Amortization — the same idea for intangible assets (patents, brands, acquired customer relationships).
Why it's used
EBITDA lets you compare the operating performance of companies with very different debt loads, tax situations and capital-spending histories. It anchors a common valuation shorthand — the EV/EBITDA multiple (enterprise value ÷ EBITDA) — used in M&A and public markets because it's capital-structure neutral. It also appears in debt covenants: lenders often cap a borrower's net-debt-to-EBITDA ratio, so treasurers watch it closely.
The criticism — and it's serious
Warren Buffett and Charlie Munger have argued for decades that EBITDA misleads. The add-backs, they note, are real costs, not free passes. Depreciation is the prime target: a factory or fleet wears out and must eventually be replaced with real cash — Buffett, in a Berkshire shareholder letter, asked whether managers think "the tooth fairy pays for capital expenditures." Munger was blunter, calling EBITDA "bullshit earnings" and "horror squared" — the second horror being that business schools taught it after, in his telling, investment bankers invented it to make deals look better, as widely reported.
A second issue is adjusted EBITDA, which isn't defined by accounting standards (GAAP) and has no fixed formula. Companies can add back stock-based pay, "restructuring" charges (that somehow recur yearly), litigation costs and more — making a struggling business look operationally sound. Because it's non-GAAP, the burden falls on the reader to reconstruct reality.
EBITDA vs. free cash flow vs. net income
Net income is the GAAP bottom line after everything. Free cash flow subtracts capital spending from operating cash flow — the cash a business actually throws off after maintaining its assets, which Buffett considers the more honest measure. EBITDA sits between: more comparable across companies than net income, but less honest about cash than free cash flow. The gap between EBITDA and free cash flow is widest in exactly the capital-heavy industries — airlines, telecoms, energy, chip fabs — where EBITDA is most quoted.
Where it works, and where it fails
EBITDA is most useful comparing similarly-financed businesses or for a quick cross-border valuation screen. It's most dangerous for capital-intensive companies whose assets genuinely wear out, and for heavily indebted firms where interest is a dominant, real cost. There, ignoring depreciation and interest isn't simplification — it's misrepresentation.
What to watch in an earnings report
When a company touts EBITDA — especially adjusted EBITDA — ask: what exactly was added back, and is it truly one-off? How big is the gap between EBITDA and free cash flow? And how much debt is there, so that ignoring interest flatters the picture? EBITDA is a useful first screen. It is a poor final answer.
