MAIN Main Street Capital

Main Street is a principal investment firm that primarily provides long-term debt and equity capital to lower middle market companies and debt capital to middle market companies. Main Street's portfolio investments are typically made to support management buyouts, recapitalizations, growth financings, refinancings and acquisitions of companies that operate in diverse industry sectors. Main Street seeks to partner with entrepreneurs, business owners and management teams and generally provides 'one stop' financing alternatives within its lower middle market portfolio. Main Street's lower middle market companies generally have annual revenues between $10 million and $150 million. Main Street's middle market debt investments are made in businesses that are generally larger in size than its lower middle market portfolio companies. Main Street, through its wholly owned portfolio company MSC Adviser I, LLC ('MSC Adviser'), also maintains an asset management business through which it manages investments for third parties. MSC Adviser is registered as an investment adviser under the Investment Advisers Act of 1940.
