The Riverside Company has sold portfolio company DuBois Chemicals to Aurora Capital Group. Harris Williams acted as the exclusive financial advisor to DuBois in the transaction. DuBois provides chemical solutions for metal cutting, cleaning and surface finishing applications, serving the industrial, transportation, pulp & paper and water treatment end markets. Riverside acquired the company in 2008 alongside a minority investment from New Canaan Funding. During its four-year hold period with the firm, total sales rose by 105% and EBITDA by 221%. The firm sponsored four add-on acquisitions for the company and improved its pricing strategies and sales and marketing approach. The deal marked Riverside's 14th exit of the year.
