Plexus Capital, a growth capital provider to lower-middle-market companies, has raised $150 million in private capital from its limited partners for its Plexus Fund III. Pending final SBA approval, this private capital will be combined with leverage from the SBA in the same amount for total available investment capital of $300 million for the fund. Based in North Carolina, Plexus invests across a broad range of industries and typically in privately-held, U.S.-based businesses. The firm most often funds growth, acquisitions, leveraged buyouts, management buyouts and stock repurchases.
