If P/E is the metric everyone quotes, EV/EBITDA is the one professional analysts often trust more — because it fixes P/E's biggest blind spot: debt.
The problem EV/EBITDA solves
P/E only looks at equity value (share price) against equity earnings (profit after interest and taxes). But two companies can have the exact same P/E while one funds itself with almost no debt and the other is loaded with it. P/E can't see that difference — EV/EBITDA can.
Breaking down the formula
Enterprise Value (EV) = market cap + total debt − cash
This is the true cost to acquire the whole business, not just its shares — because whoever buys the company also inherits its debt (a cost) and gets its cash (an offset). It's a more complete price tag than market cap alone.
EBITDA = Earnings Before Interest, Taxes, Depreciation, and Amortization
This approximates the cash-generating power of the core business, stripped of financing decisions (interest expense depends on how much debt a company chose to take on — not how good the business is) and non-cash accounting items (depreciation/amortization).
EV/EBITDA = Enterprise Value ÷ EBITDA
Why this matters in practice
Imagine two companies with identical share prices and identical net income — same P/E. Company A has no debt. Company B has $2 billion in debt. On P/E, they look equally "expensive." On EV/EBITDA, Company B looks noticeably more expensive, because its enterprise value includes that $2 billion an acquirer would have to absorb.
This is exactly why EV/EBITDA is the standard metric in M&A and private equity — it's the number that reflects what it'd actually cost to buy the whole company, debt included.
When it's especially useful
- Capital-intensive industries (manufacturing, telecom, energy) where depreciation is large and distorts net income.
- Comparing companies with different capital structures — one debt-heavy, one debt-light.
- Cross-border comparisons, since it strips out tax-rate differences between countries.
Its own limitation
EBITDA ignores capital expenditure — the real cash a company has to keep spending on equipment, facilities, or infrastructure just to keep the business running. A company can have great EBITDA and still burn cash if it needs constant heavy capex to stay competitive. That's why Investingg AI's research pairs EV/EBITDA with free cash flow yield, not either metric alone.
