EV/EBITDA vs P/E: Which Valuation Multiple Should You Trust?

P/E (Price to Earnings) is the most commonly cited valuation multiple, but it has a significant blind spot: it completely ignores debt. EV/EBITDA fixes this by valuing the whole business, not just the equity portion.

What P/E leaves out

P/E compares a company's share price to its earnings per share — but earnings are calculated after interest payments on debt are already subtracted. Two companies with identical operating performance but very different debt loads can show very different P/E ratios, purely because of how much interest expense each pays — not because their underlying businesses differ in quality.

What EV/EBITDA measures instead

Enterprise Value (EV) = Market Cap + Total Debt − Cash. This represents the theoretical full cost to acquire the entire company, debt included, since a buyer would need to pay off existing debt as part of any acquisition. EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortization) strips out the effects of financing and accounting choices, focusing purely on operating performance.

Comparing EV to EBITDA gives a valuation multiple that's comparable across companies with very different capital structures — a heavily indebted company and a debt-free one become directly comparable in a way P/E can't achieve.

A scenario where this matters

Two companies generate identical operating profit. Company A has no debt; Company B is heavily leveraged and pays substantial interest expense, reducing its net earnings and inflating its P/E ratio relative to Company A — even though their underlying businesses perform identically. EV/EBITDA would correctly show both companies trading at similar multiples, revealing that the P/E difference was purely a financing artifact, not a reflection of business quality.

When P/E is still useful

P/E remains simple, widely available, and intuitive, and works reasonably well for comparing similarly-capitalized companies within the same industry. It's a fine quick screening tool — the key is knowing its blind spot and reaching for EV/EBITDA specifically when comparing companies with meaningfully different debt levels.

Industry matters for interpreting either multiple

Capital-intensive industries (utilities, telecom) typically trade at different baseline EV/EBITDA multiples than asset-light industries (software, services) — always compare multiples within the same industry, never across unrelated sectors.
