What it means
Market capitalisation tells you what the equity is worth, but it ignores how the company is financed. Two companies could have identical market capitalisations of $500 million, yet one has no debt and $100 million of cash, while the other has $300 million of debt and no cash.
An acquirer buying the first company effectively also acquires $100 million of cash it can immediately use or distribute, while an acquirer of the second must also take on $300 million of debt obligations. Enterprise value adjusts for exactly this difference, making the two companies properly comparable on the value of their underlying operations.
The logic runs like this: an acquirer buying all the equity would need to pay off existing debt (or assume it, which is economically similar), so debt is added to market capitalisation. At the same time, any cash sitting on the balance sheet effectively reduces the net cost of the acquisition, since the acquirer could immediately use that cash to help fund the purchase or pay down the newly assumed debt, so cash is subtracted.
Enterprise value is the standard denominator-neutral value used across valuation multiples such as EV/EBITDA, EV/Revenue and EV/Free Cash Flow, precisely because those multiples compare the value of the whole operating business against a measure of operating performance that is also unaffected by financing structure. Using market capitalisation instead of enterprise value in these multiples would unfairly penalise companies that use more cash and reward companies that carry more debt, even if their underlying operations are identical.
A more complete formula also adds minority interest and preferred stock, since these represent additional claims on the business beyond common equity, though for many straightforward comparisons the simplified market capitalisation, debt and cash version is sufficient.
In practice
Real-world examples.
Example
A heavily indebted airline can have an enterprise value far above its market capitalisation, since its substantial debt load adds much more than its modest cash balance subtracts.
Example
A cash-rich technology company with little or no debt can have an enterprise value noticeably below its market capitalisation, because its large cash pile is subtracted with nothing offsetting it.
Example
Two retailers with the same market capitalisation of $2 billion can have very different enterprise values, one at $2.3 billion because of debt from store expansion, the other at $1.7 billion because it holds a large cash reserve.
Think of it
“Enterprise value is like the real price of a house including the mortgage you'd assume. Market cap is just the equity; EV includes the full cost to own it.
Formula
Calculation
Enterprise Value = Market Capitalisation + Total Debt minus Cash and Cash Equivalents
Worked example. A mid-sized manufacturer has 20 million shares outstanding trading at $45 per share, total debt of $180 million, and cash and equivalents of $60 million.
Market capitalisation = 20,000,000 x $45 = $900,000,000
Enterprise value = $900,000,000 + $180,000,000 minus $60,000,000 = $1,020,000,000
Although the equity is valued at $900 million, an acquirer looking to buy the whole business would effectively need to account for $1.02 billion once the company's debt and cash position are factored in. If the company instead had no debt and $200 million of cash, its enterprise value would be $900,000,000 + $0 minus $200,000,000 = $700,000,000, a very different figure despite an identical market capitalisation.Case study
Seen in the real world.
An investor comparing two grocery chains for a potential investment found their price-to-earnings ratios nearly identical, suggesting similar valuations. Digging into enterprise value told a different story. Chain A had a market capitalisation of $4 billion, debt of $2.5 billion from an aggressive store expansion programme, and only $200 million of cash, giving an enterprise value of $6.3 billion.
Chain B had the same $4 billion market capitalisation, but just $400 million of debt and $900 million of cash, giving an enterprise value of $3.5 billion. On an EV/EBITDA basis, Chain B was trading at a noticeably cheaper multiple than Chain A despite their identical price-to-earnings ratios and market capitalisations, because Chain A's higher debt burden was invisible in the simple equity-based comparison. The investor concluded that Chain B represented better value once the true cost of acquiring the whole business, debt included, was taken into account.
Watch out
Common mistakes.
- Using market capitalisation and enterprise value interchangeably. They answer different questions, equity value versus whole-business value, and mixing them up leads to comparing companies on an unequal basis.
- Forgetting to subtract cash, which overstates enterprise value and can make a cash-rich company look more expensive relative to its operating performance than it really is.
- Ignoring minority interest and preferred stock in more complex company structures, understating true enterprise value for companies that have these additional claims.
Questions
People also ask.
Can enterprise value be negative?
Yes, though rarely. It happens when a company's cash exceeds its market capitalisation plus debt, implying the market values the operating business at less than its net cash position.
Why is enterprise value used instead of market capitalisation in valuation multiples?
Because it neutralises differences in capital structure, letting analysts compare the value of operating businesses on a like-for-like basis regardless of how much debt or cash each one carries.
Does enterprise value change if a company takes on more debt without changing anything else?
Yes. All else equal, additional debt increases enterprise value, since it represents an additional claim an acquirer would need to account for.
