Main Street Capital Corporation was founded in 1997. The Company is an investment firm focused on providing customized debt and equity financing to lower middle market "LMM" companies and debt capital to middle market "Middle Market" companies. Its portfolio investments are typically made to support management buyouts, recapitalizations, growth financings, refinancings and acquisitions of companies that operate in diverse industry sectors. It seeks to partner with entrepreneurs, business owners and management teams and generally provide "one stop" financing alternatives within the Company's LMM portfolio. The Company invests in secured debt investments, equity investments, warrants and other securities of LMM companies based in the United States and in secured debt investments of Middle Market companies generally headquartered in the United States. In addition to its LMM investment strategy, the Company pursues investments in Middle Market companies. Its Middle Market portfolio investments consist of direct investments in or secondary purchases of interest-bearing debt securities in privately held companies that are generally larger in size than the LMM companies included in the Company's LMM portfolio. Its Middle Market portfolio debt investments are generally secured by either a first or second priority lien on the assets of the Company and typically have an expected duration of between three and five years. The Company competes for investments with a number of investment funds, including private equity funds, mezzanine funds, BDCs, and SBICs, as well as traditional financial services companies such as commercial banks and other sources of financing.
