Two companies can have the same stock-market value while carrying very different amounts of debt and cash. Market capitalisation and enterprise value help describe that difference, but they should not be treated as interchangeable price tags.
Begin with the equity
Market capitalisation is the share price multiplied by the number of outstanding shares. In a fictional example, a company with ten million shares priced at 20 currency units has a market capitalisation of 200 million. This describes the market value of its equity at that price and share count.
A simplified enterprise-value calculation adds debt to market capitalisation and subtracts cash. If the same fictional company has 60 million in debt and 15 million in cash, the simplified result is 245 million. Real calculations can also include preferred equity, non-controlling interests and other adjustments, depending on the definition used.
CFA Institute’s reading on price and enterprise-value multiples distinguishes equity-based measures from measures relating to the enterprise’s broader capital. That distinction helps explain why the numerator and denominator of a valuation ratio must belong together.
Keep the dates and definitions aligned
A current share price paired with an old share count can produce a misleading calculation. Debt and cash usually come from a financial statement with its own reporting date. Note those dates rather than presenting the result as if every input were measured simultaneously.
When comparing data providers, inspect their methodology. A difference may reflect treatment of leases, restricted cash or other items rather than an arithmetic mistake. Do not quietly mix one provider’s enterprise value with another provider’s differently adjusted earnings figure.
Use the number to ask a better question
Neither measure tells you by itself whether a share is attractive. The fictional calculation is a way to understand the categories, not an investment recommendation. Before interpreting a multiple, ask what obligations and resources are included and whether the comparison companies are sufficiently alike.
