Over the course of Main Street's investment, the Company acquired five additional businesses, opened four greenfield locations, and invested heavily in its rental fleet to drive double-digit annual organic growth.  Main Street's debt investment was refinanced in February 2020, while Main Street maintained its equity ownership in the Company.
