The Riverside Co. has sold Long Beach, California-based MNX Global Logistics to Audax Private Equity. MNX is a leading provider of time-critical logistics services for sensitive, high-value goods. The company offers a portfolio of expedited shipping, supply chain management and freight services across a comprehensive global network. Riverside bought the company in 2012 to help the management team grow its high-touch transportation services platform. MNX’s sales more than doubled during Riverside’s hold, utilizing Riverside’s investment and operational teams. “MNX had incredible potential when we first partnered with them,” Riverside Managing Partner Suzy Kriscunas said in a statement. “Over the course of our hold, we enjoyed working closely with the management team to expand MNX’s service offering and global footprint.” Riverside complemented existing growth by executing two add-on acquisitions in international markets. Singapore-based Aero Express Logistics enhanced MNX’s offering for aerospace customers in the Asia-Pacific region while Melbourne-based Logical Freight Solutions furthered the company’s specialized capabilities for global health care and life sciences customers. Working with Kriscunas on the transaction for Riverside were fellow partners Peter Tsang and Drew Flanigan, as well as Operating Partner Steve Stubitz, Senior Associate Fei Ren and Associate Cord Walker. BB&T Capital Markets and Jones Day advised Riverside on the transaction.
