Market cap
Market capitalization (market cap) is the total market value of a company's outstanding shares, calculated as: Market Cap = Share Price times Total Shares Outstanding. It represents the aggregate price the public market places on the equity of a company at a point in time. Market cap is used to classify companies by size -- typically micro-cap, small-cap, mid-cap, and large-cap -- and is a commonly cited measure of a public company's scale. However, market cap reflects only equity value and ignores debt; enterprise value (market cap plus net debt) is the more complete measure of total company value and the standard basis for acquisition pricing and EBITDA multiples.
Problem & Application
A publicly traded campground REIT has 20 million shares outstanding trading at $25 per share, giving a market cap of $500 million. The REIT also carries $300 million in mortgage debt and holds $50 million in cash, so its enterprise value is $500M + $300M - $50M = $750 million. If the REIT's EBITDA is $75 million, the EV/EBITDA multiple is 10x -- a figure acquirers use to benchmark against comparable transactions. A private campground portfolio being sold would reference this multiple to anchor its own valuation expectations. Market cap alone would imply a 6.7x equity multiple, which understates total acquisition cost and leads to mispriced deals if not adjusted for the debt that transfers with the business.
In Short
Market cap is a useful indicator for valuing companies, but it should be used alongside other financial metrics for comprehensive evaluation.
