When should I use EV/EBITDA instead of P/E for equity valuation?

EV/EBITDA and P/E are both valuation multiples, but they measure different things and are appropriate in different situations.

Fundamental Difference:

• P/E = Price per share / Earnings per share → equity value to equity holders' income
• EV/EBITDA = Enterprise Value / EBITDA → total firm value (equity + debt - cash) to pre-interest, pre-tax, pre-depreciation earnings

Use P/E When:

• Companies have similar capital structures (leverage levels)
• Earnings are positive and relatively stable
• Comparing equity-only returns to shareholders
• The industry has low capital intensity (tech, services, consumer brands)

Use EV/EBITDA When:

• Companies have different leverage levels — EV/EBITDA neutralizes the effect of debt because EBITDA is before interest
• Earnings are negative but EBITDA is positive (common in turnarounds, high-growth firms)
• Capital-intensive industries where depreciation policies distort P/E (telecom, utilities, airlines, real estate)
• Cross-border comparisons where different tax regimes make net income incomparable
• Evaluating takeover targets (acquirers buy the whole enterprise, not just equity)

Practical Framework:

Industry Conventions:

• Telecom / Infrastructure: EV/EBITDA (heavy depreciation, different leverage)
• Banking / Financial: P/E (or P/B) — EBITDA is meaningless for financial firms because interest is an operating cost
• Tech / SaaS: EV/Revenue or EV/EBITDA for pre-profit companies, P/E for profitable ones
• Real Estate: P/FFO (Funds from Operations) — a REIT-specific variant

Key Limitation of EV/EBITDA: It ignores capex. Two companies with identical EBITDA but vastly different maintenance capex requirements are not equally valuable. This is why some analysts prefer EV/EBIT or EV/FCFF.

Exam tip: If the question mentions companies in the same industry but with different debt levels, EV/EBITDA is almost always the better choice. If the question mentions negative earnings, P/E is undefined and EV/EBITDA is the way to go.
