Main Street Capital (MAIN) is a business development company, or BDC. All BDCs are basically middle market lenders, which means they lend or take equity stakes in the 200,000 or so subprime businesses that generate about a third of the U.S. economy.

The firm deals mostly with lower middle market companies that have annual revenue between $10 million and $150 million and EBITDA ranging from $3 million to $20 million.
