What is the difference between enterprise value and equity value, and when should I use EV-based multiples instead of price-based ones?

Enterprise value (EV) and equity value (market cap) represent different claims on a company. Understanding the distinction is fundamental to proper valuation.

Equity Value (Market Cap):

Market Cap = Share Price x Shares Outstanding

This represents the value of equity holders' claim on the company. It's the residual after all debt and other obligations are satisfied.

Enterprise Value (EV):

EV = Market Cap + Total Debt + Preferred Stock + Minority Interest - Cash

This represents the total value of the operating business — the cost to acquire the entire firm, including taking on its debt but getting its cash.

Why EV/EBITDA Is Better for Cross-Company Comparison:

Consider two identical companies:

Based on P/E, Bramblewood looks 'cheaper' (9.1x vs. 12.0x). But this is an illusion — the lower P/E simply reflects higher financial leverage reducing net income. EV/EBITDA correctly shows both companies are valued identically at the operating level.

The Matching Principle:

Use EV-based multiples with metrics before interest payments:

• EV / EBITDA
• EV / EBIT
• EV / Revenue
• EV / Invested Capital

Use price-based multiples with metrics after interest (available to equity):

• P / E (Earnings = after interest and taxes)
• P / B (Book equity = after deducting debt)
• P / CF (Cash flow to equity = after debt service)

Common EV Calculation Mistakes:

1. Forgetting to add minority interest
2. Using gross debt instead of net debt (or vice versa — be consistent)
3. Including operating leases in some comparisons but not others
4. Not adjusting for excess cash vs. operating cash

Exam tip: If the exam gives you market cap, debt, and cash, you should be able to compute EV instantly. Also remember that EV/EBITDA is the preferred multiple for M&A analysis because acquirers buy the whole business (equity + debt). A common question tests whether mixing EV with a post-interest metric (like EV/Net Income) is a valuation error.
