Market cap or enterprise value: what should you look at?

2026-07-25 · By Lubin Danilo, founder of Lubin Investment

Market capitalization (share price multiplied by the number of shares) ignores a company's debt and cash. Enterprise value corrects for this by adding net debt. Two companies with the same market cap can therefore cost very different amounts to buy outright, depending on what they owe or hold in cash.

Two ways to answer "how much is this company worth"

Market capitalization is the number most often quoted when talking about a public company: it is simply the share price multiplied by the total number of shares outstanding. It is the price you would theoretically pay today to buy up every share of the company on the market. It is a simple, immediate figure, and the one that appears prominently on most financial sites.

But this figure ignores a detail that can change everything: if you actually bought the entire company, you would not just inherit its shares, you would also inherit everything it owes and everything it holds in cash. Enterprise value (often abbreviated EV) corrects for this: it adds to market capitalization the company's net debt, meaning its total debt minus its available cash. If a company owes more than it holds in cash, its enterprise value exceeds its market cap. If it holds more cash than debt, the opposite happens: its enterprise value is lower than its market cap, because a buyer could in theory use that excess cash to pay back part of what they just spent.

Real example: when cash melts away the real bill (Garmin)

Garmin, the maker of GPS devices and smartwatches, has a market capitalization of roughly $45.6 billion. But its balance sheet carries only $165 million in total debt, a nearly negligible sum, against $2.28 billion in available cash. Its net debt is therefore negative: the company holds, in pure cash, about $2.1 billion more than it owes.

In practice, if you bought Garmin outright for $45.6 billion, you would immediately recover that net cash cushion sitting in the company's accounts, which brings the real cost of the deal down to roughly $43.5 billion once that cash is used to reimburse part of the purchase. That is exactly what enterprise value measures: it is LOWER than market cap, because Garmin holds far more cash than debt. This is a situation often seen at mature companies that generate a lot of free cash flow (the money left over after expenses AND investments) without a large need to borrow to fund growth.

Real example: when debt weighs more than the cash on hand (IBM)

IBM illustrates the opposite case. Its market capitalization sits around $201.3 billion, but its balance sheet carries $64.6 billion in total debt against just $13.6 billion in available cash, a net debt of roughly $51 billion. This debt largely comes from financing its operations (IT leasing offered to customers, a legacy of numerous acquisitions) and its multi-billion dollar, multi-year bet on quantum computing.

If you bought IBM outright for $201.3 billion, you would immediately inherit that $51 billion in net debt to repay or assume, which brings the real cost of the deal to roughly $252 billion once that debt is accounted for. Here, enterprise value is HIGHER than market cap, by about 25%. This is not necessarily a problem (debt that funds a profitable activity or a strategic investment is not a warning sign in itself, see my article on debt in my method), but it is a real cost that market capitalization alone never shows.

Why this matters in practice when judging a valuation

Most valuation ratios you come across (the P/E, the P/FCF I use in my method) are calculated with market capitalization in the numerator. They therefore compare the price paid by SHAREHOLDERS to earnings or cash generated, without accounting for what the company otherwise owes creditors. Two companies with exactly the same P/FCF can therefore represent very different risks if one carries massive net debt and the other a net cash cushion: the one with net cash has, in a sense, an extra margin of safety (it could repay its debt instantly if needed, or simply has none), while the one with high net debt must generate enough cash every year to meet its obligations before even thinking about rewarding shareholders.

This is exactly why other ratios, such as EV/EBITDA, deliberately use enterprise value rather than market capitalization in the numerator: they aim to answer a slightly different question, closer to 'what would it really cost to buy this entire company, debt included', rather than 'what are shareholders paying today'. Both angles are useful, but answer two distinct questions, and conflating them can distort a comparison between two companies in the same sector with very different balance sheet structures.

How I use this distinction in my method

In my quality framework, I never settle for the headline P/FCF without first checking what the balance sheet carries: a net debt to free cash flow ratio (how many years of cash it would take to fully repay net debt) is one of my criteria, precisely because it fills in information that market capitalization alone never provides. A company like Garmin, with its net cash position, starts with a margin of safety that the P/FCF alone never reveals. A company like IBM, with tens of billions in net debt, deserves that you FIRST understand what that debt is for (funding a profitable activity, a strategic bet, or simple historical accumulation) before judging whether the headline price is reasonable. Neither market cap alone, nor enterprise value alone, tells the whole story: it is comparing the two, and understanding the gap between them, that provides the real information. You can dig into how this reasoning applies to a concrete multiple in my article on EV/EBITDA, why rising debt is not automatically a problem in my article on debt in my method, and my full methodology.

Market capitalization = share price × number of shares. This is what it would theoretically cost to buy up every outstanding share on the market.
Enterprise value (EV) = market capitalization + net debt (total debt minus available cash). It measures the real cost of buying the ENTIRE company, debt included.
Net cash example (Garmin): market cap $45.6B, negative net debt of about $2.1B ($165M debt versus $2.28B cash) → enterprise value LOWER than market cap, roughly $43.5B.
High net debt example (IBM): market cap $201.3B, net debt of about $51B ($64.6B debt versus $13.6B cash) → enterprise value HIGHER than market cap, roughly $252B (+25%).
Why it matters: P/FCF and P/E use market cap (what shareholders pay), while EV/EBITDA uses enterprise value (the total buyout cost, debt included). Two companies with the same P/FCF can carry very different risk depending on their net cash or net debt position.

FAQ

What is the difference between market capitalization and enterprise value?

Market capitalization is the share price multiplied by the number of shares. Enterprise value adds net debt (total debt minus available cash), to measure the real cost of buying the entire company, debt included.

Why is Garmin's enterprise value lower than its market capitalization?

Garmin carries only $165 million in total debt against $2.28 billion in available cash, a negative net debt of about $2.1 billion. This excess net cash pushes enterprise value below market capitalization.

Why does IBM's enterprise value exceed its market capitalization by 25%?

IBM carries $64.6 billion in total debt against just $13.6 billion in available cash, a net debt of roughly $51 billion. A buyer acquiring IBM outright would inherit this net debt, which pushes the real cost above the headline market cap.

Should you use market cap or enterprise value to judge a stock's price?

Both are useful but answer different questions: P/FCF or P/E (based on market cap) measure what shareholders pay; EV/EBITDA (based on enterprise value) measures the total buyout cost, debt included. Comparing the two helps spot whether a company carries net debt or net cash that changes the real risk.

Is high net debt always a negative signal?

No, not automatically: debt that funds a profitable activity or a strategic investment can be reasonable. What matters is checking what that debt is for before judging whether the price shown by market capitalization alone is truly reasonable.

And spotting the best stocks was just as time-consuming, even with my own well-defined checklist. So I put my software development background to work to build this software, base my investment strategy on its results, and share it with people who share the same passion as me.
