An acquisition-style valuation multiple: Enterprise Value (market cap + net debt) divided by operating earnings before accounting adjustments. Compares companies fairly regardless of their capital structure.
(Market Cap + Net Debt) / EBITDAUnlike P/E, this metric accounts for debt — two companies with identical operations but different leverage will show similar EV/EBITDA. Low vs history suggests the total business is modestly priced.
- EBITDA ignores capital expenditure. For asset-heavy businesses (airlines, mining, utilities), this understates the real cost — use EV/EBIT or EV/FCF instead.
- Large acquisitions temporarily spike net debt and can distort the ratio for 1–2 years during integration.
