EBITDA
Definition
EBITDA stands for Earnings Before Interest, Taxes, Depreciation, and Amortization. It is a non-GAAP financial metric that measures a company's operating performance by removing the effects of financing decisions, accounting policies, and tax environments. It offers a useful, albeit incomplete, view of a company's core operating profitability.
Origins
The term EBITDA emerged in the 1980s during the rise of leveraged buyouts (LBOs). It became popular among investment bankers and private equity firms to assess the ability of a company to service debt, by isolating cash-generating potential before financial and non-cash costs.

Usage
EBITDA is used by:
-
Investors and analysts to compare companies across industries.
-
Private equity firms to assess acquisition targets.
-
Lenders and rating agencies for debt capacity analysis.
-
Corporate management to evaluate operating performance.
How EBITDA Works
EBITDA removes non-operational and non-cash items:
-
Interest: Reflects capital structure, not operations.
-
Taxes: Affected by location and tax strategies.
-
Depreciation & Amortization (D&A): Non-cash accounting expenses tied to past investments.
By adding back these costs, EBITDA presents a measure of earnings generated from core operations, though it is not a direct measure of operational cash flow as it excludes changes in working capital.
Key Takeaway
-
EBITDA isolates operating performance from financing and accounting decisions.
-
It is a non-GAAP measure, meaning it is not required or standardized under IFRS or US GAAP.
-
EBITDA is widely used in valuation (EV/EBITDA) and leverage ratios.
-
It can be manipulated if companies selectively adjust or exclude certain costs.

Types & Variations
1. Adjusted EBITDA
-
Excludes non-recurring, irregular, or one-time expenses/income.
-
Common adjustments: stock-based compensation, restructuring charges, legal settlements.
2. EBITDA Margin
-
Expresses EBITDA as a percentage of revenue.
-
Useful for comparing profitability across companies or over time.
3. Normalized EBITDA
-
Adjusted for seasonality or cyclical trends to reflect sustainable earnings.
-
Used in M&A and DCF models.

Forecasting: EBITDA is projected in financial models to build valuation, assess performance, and guide decisions.
Nuances & Complexities
-
Not Cash Flow: EBITDA excludes capital expenditures, which can be significant in capital-intensive industries.
-
Excludes Working Capital Changes: It doesn’t account for changes in receivables, payables, and inventory.
-
Non-Standardized: No consistent method; companies may report EBITDA differently.
-
Overuse Warning: Analysts should also review operating cash flow and net income for a complete picture.

Real-World Applications
Example 1: EV/EBITDA Valuation
Company A has:
-
EBITDA = $25M
-
Enterprise Value = $250M
-
EV/EBITDA = 10×
This multiple is used to compare with industry peers or acquisition targets.
Example 2: Leveraged Buyout (LBO)
Private equity uses EBITDA to estimate how much debt the company can carry, often targeting Net Debt/EBITDA ratios of 3× to 5×.
Example 3: Earnings Normalization
A company with one-time restructuring costs adds them back to present adjusted EBITDA for a more accurate picture of recurring profitability.
