What Is Enterprise Value?

📋 What you're given

You're in an interview and the interviewer asks: "Why don't we just use market capitalization to value a company? What's missing, and how would you bridge from market cap to Enterprise Value?"

1. Task Overview

Task: explain why market capitalization alone is an incomplete measure of a company's value, and demonstrate how to bridge from market cap to Enterprise Value using a real example.

Step 1: Given Data — Two Companies, Same EBITDA

Both companies generate the same operating profit, but their capital structures are very different.

Line Item	Company A	Company B
Market Capitalization	$800m	$950m
Total Debt	$300m	$50m
Cash & Equivalents	$50m	$100m
Minority Interest	$20m	$0m
EBITDA	$150m	$150m

Step 2: Enterprise Value

Show Enterprise Value Formula

Enterprise Value = Market Capitalization + Total Debt + Minority Interest − Cash & Equivalents

Using this formula, compute Enterprise Value for both Company A and Company B.

Step 3: EV/EBITDA Multiple

Show EV/EBITDA Formula

EV/EBITDA = Enterprise Value / EBITDA

Using this formula, compute the EV/EBITDA multiple for both companies and compare it to what market cap alone would suggest.

💡 Model answer

Try answering out loud first — then reveal the model answer and compare.

Step 1: Enterprise Value

Enterprise Value = Market Cap + Total Debt + Minority Interest − Cash

Line Item	Company A	Company B
Market Capitalization	$800m	$950m
+ Total Debt	$300m	$50m
+ Minority Interest	$20m	$0m
− Cash & Equivalents	($50m)	($100m)
Enterprise Value	$1,070.0m	$900.0m

Enterprise Value represents the price a buyer would have to pay to acquire the entire operating business free and clear of its financing structure — it captures both what the equity holders own (market cap) and what the debt holders are owed, net of the cash sitting on the balance sheet that could immediately retire some of that debt. Because it strips out how the company happens to be financed, it puts businesses with different capital structures on a comparable footing.

Step 2: EV/EBITDA Multiple

EV/EBITDA = Enterprise Value / EBITDA

Company A: $1,070.0m / $150.0m = 7.1x

Company B: $900.0m / $150.0m = 6.0x

Looking only at market cap, Company B appears to be worth more ($950m vs. $800m). But once debt and cash are factored in, Company A is actually the more expensive business on an operating basis — it trades at a higher EV/EBITDA multiple. That's the core reason interviewers push on this: market cap only tells you what the equity is worth, and equity value shrinks or grows mechanically depending on how much debt a company carries. EV/EBITDA is capital-structure-neutral, which is why it's the standard multiple for comparing companies with different leverage profiles, such as in comparable company analysis or precedent transactions.

Final Results

Company A Enterprise Value: $1,070.0m (7.1x EBITDA)
Company B Enterprise Value: $900.0m (6.0x EBITDA)

This EV bridge is the starting point for nearly every valuation method that follows — comparable company analysis, precedent transactions, and DCF all produce an Enterprise Value first, which then has to be bridged back down to Equity Value to arrive at a price per share.

Would you like to walk through the reverse bridge — going from Enterprise Value back to an implied share price?

⚠️ Common mistakes

Comparing companies on market cap or P/E without adjusting for differences in leverage — this ignores how much of the business is actually funded by debt.
Forgetting to subtract cash in the EV bridge, which overstates Enterprise Value and the resulting multiple.
Confusing Enterprise Value with Equity Value — EV values the whole operating business, Equity Value only the shareholders' claim on it.
Ignoring minority interest and preferred stock when a company has non-wholly-owned subsidiaries, which understates Enterprise Value.
Assuming a higher market cap always means a "bigger" or "pricier" business, without checking the EV-based multiple first.
