Enterprise value answers a more complete question than market cap alone — not "what is the equity worth" but "what would it actually cost to acquire this whole company, debt included."
The Formula and Purpose
Enterprise value = market capitalization + total debt − cash and cash equivalents. An acquirer buying a company would need to real-world take on its debt and would offset that cost with its cash reserves — EV captures both, where market cap alone captures neither. Two companies with identical market caps can have very different EVs if one carries heavy debt and thin cash reserves while the other is debt-free with a large cash pile.
EV/EBITDA (enterprise value divided by earnings before interest, taxes, depreciation, and amortization) is a common valuation multiple precisely because it neutralizes differences in capital structure — making it a fairer comparison tool than P/E when comparing companies with meaningfully different debt levels.
Someone Comparing Two Similarly-Sized Companies by Market Cap: Check enterprise value too — debt and cash differences can mean very different acquisition costs despite similar market caps.
Someone Evaluating a Company With Heavy Debt: EV captures that debt burden explicitly — market cap alone would understate the company's true cost to acquire.
Use Enterprise Value the Way
- Calculate EV alongside market cap for any company carrying meaningful debt.
- Use EV/EBITDA when comparing companies with different capital structures.
- Don't rely on market cap alone to judge a company's true acquisition cost.
