One Rock Capital Partners and minority co-investor Babson Capital Management have acquired Summit Research Labs from MVC Capital. Based in Huguenot, NY, Summit manufactures active ingredients used in antiperspirants. About half of the company's revenues stream from customized formulations developed for specific customers. As part of the sale, MVC provided Summit with a $22 million second lien loan. Prior to the closing of the sale, MVC also purchased Summit's spray drying business, which will now operate as a standalone company.
