When you buy a house with a mortgage, the real cost isn't just your down payment — it's the full price, debt and all.
Enterprise value applies the same logic to companies. It is what an acquirer actually pays, not just the equity slice.
Market cap only captures what existing shareholders are owed. EV captures the entire capital structure — equity plus all obligations minus available cash.
The formula#
Enterprise Value = Market Cap + Total Debt − Cash & EquivalentsAdd the equity value, add the debt you'd inherit, subtract the cash you'd receive. The result is the economic cost of owning the entire business — the number that drives every real M&A negotiation.
What the market looks like right now#
Across 5,362 US-listed stocks with a reported enterprise value, the median sits at $1.3B.
The median EV runs higher than the median market cap because most companies carry more debt than cash — adding net debt to equity pushes the total cost above the equity price for the majority of businesses.
Only 96 companies have an enterprise value above $200.0B, meaning their combined equity and debt makes them genuinely mega-scale. At the bottom, 1,708 companies fall below $300M in total acquisition value.
Microsoft: when EV moves in both directions#
Microsoft Corporation (MSFT) has an enterprise value of $2.92T. MSFT carries significant long-term debt from acquisitions and also holds tens of billions in cash — the two roughly offset, which is why EV and market cap sit close together.
That balance rarely holds when you look at the targets MSFT acquires. When Microsoft closed the Activision Blizzard deal in 2023 for a headline equity price of $68.7 billion, Activision held approximately $4.4 billion in net cash. The enterprise value of the deal was closer to $64.3 billion — nearly $4 billion below the equity price.
Flip the direction and you get the Twitter acquisition — $44B equity, $3.5B net debt, $47.5B EV. EV was higher than the reported price.
Both cases are the same math: EV is what you actually pay when you own the debt and the cash. Sometimes that's more than market cap. Sometimes less. Always different.
Where enterprise value breaks#
Stale balance sheet data. EV is only as current as the debt and cash figures. If a company just closed a $10B debt issuance or sold a subsidiary, the reported EV may lag by a quarter. Always check when balance sheet data was last reported.
Off-balance-sheet obligations. Operating leases, pension deficits, and contingent liabilities often don't appear in the debt figure. For capital-intensive sectors like retail and airlines, these can be substantial.
Cash isn't always reachable. A company with $20B in cash held overseas may face tax friction to repatriate it. Cash stranded in subsidiaries isn't always as useful as it looks in the formula.
Preferred stock and minority interests. Strictly, EV should add preferred stock and minority interests. Most screeners simplify — check what's included when comparing across data providers.
How to use it#
- Replace market cap with EV when comparing across capital structures. A manufacturer with heavy debt and a software company with no debt are incomparable using market cap alone. EV levels the field.
- Use EV as the numerator in valuation multiples. EV/EBITDA and EV/Revenue are more reliable than P/E for capital-intensive industries. The denominator should be an income line available to all capital providers — not just equity holders.
- Check EV relative to net debt. If EV is 5× market cap, the company's debt load dominates the total value. That amplifies the upside if it deleverages — and the downside if earnings fall.
- Pair with free cash flow. An EV/FCF below 20 on a quality business is often more meaningful than a headline P/E, because free cash flow is what actually services and eventually retires the debt in the EV calculation.
Bottom line#
Enterprise value is the honest price of a business. Market cap is just the equity portion of the bill.
When two companies look similar on market cap but one is funded by debt and the other by equity, they are not priced the same. EV makes the comparison honest.
Every serious valuation starts with EV — not because market cap is wrong, but because it is incomplete.
