Market capitalisation is the price of all shares: share price times diluted shares outstanding. Enterprise value adds debt and subtracts cash, estimating what it would cost to buy the whole business outright. Market cap is what the equity costs; enterprise value is what the company costs.
The arithmetic, and why it exists
Enterprise value is market cap plus total debt, minus cash and equivalents. The logic is an acquisition: buy every share and you also inherit the debt, which you must repay, and you gain the cash, which you can use to offset the price.
Two companies with identical operations and identical market caps are not equally priced if one carries $5B of debt and the other $5B of net cash. On market cap they look the same. On enterprise value they differ by $10B, and the second is dramatically cheaper.
Which one you should be using
Enterprise value for comparing companies. Any multiple built to compare two businesses should use it, because it neutralises financing decisions. This is why EV/EBITDA is more useful than P/E when the two companies carry different debt loads.
Market cap for what you own. Your claim is on the equity, so market cap is the right denominator for per-share figures and for questions about size, index inclusion and liquidity. The float matters here too, since market cap counts shares that may never trade.
When the gap is the story
Enterprise value far above market cap means heavy net debt, and the equity is the thin slice above a large obligation. Small changes in operating performance swing the equity violently, which is leverage working in both directions. Check interest coverage before anything else.
Enterprise value well below market cap means net cash. The business is cheaper than the share price suggests, and the question becomes what management intends to do with the money. Cash earning nothing while ROIC is high is a wasted opportunity, and it is a capital allocation question rather than a valuation one.
The mistakes worth avoiding
Do not treat a low enterprise value as automatically cheap. A company with negative enterprise value, where cash exceeds market cap plus debt, is usually a business the market expects to burn that cash.
And do not mix the two across a ratio. Dividing enterprise value by net income is meaningless, because the numerator covers all capital providers and the denominator is after interest has already been paid to the lenders. Pair enterprise value with EBIT, EBITDA or free cash flow, and market cap with earnings.
