Main Street Capital is a company that lends money and invests in small and medium-sized businesses across the United States. These businesses are often too small to borrow from big banks or sell stock on public markets, so they turn to firms like Main Street for funding. Main Street provides both loans and equity investments, meaning it can own a piece of the companies it backs.

Main Street makes money by collecting interest on its loans and earning returns when its portfolio companies grow or are sold. It is structured as a Business Development Company, or BDC, which requires it to pay out most of its income to shareholders as dividends. With a market cap near $4.8 billion, it is one of the largest BDCs in the country, and its internally managed structure keeps costs lower than many competitors. The main risk is that an economic slowdown could cause small businesses in its portfolio to struggle to repay their loans.
