List of Publicly Traded Micro-Cap Pharmaceutical Companies Listed on Major U.S. Exchanges

This list includes very small-sized pharmaceutical companies with market capitalizations under 300 million dollars. In the world of investing these are referred to as micro-cap stocks. We update this page at the start of every month so it is possible that during the course of a month a company’s market cap might go above 300 million. We have also separated out companies with a market cap less than 50 million dollars and these companies can be found below the micro-cap stock list.
