US transport and logistics provider Roadrunner Transportation Systems is continuing its recent run of acquisitions with the announcement this week that it is buying Active Aero Group, the expedited air and ground cargo provider, for $115m. The transaction is expected to close by the end of Roadrunner’s 2014 third quarter, subject to conditions.

“As we have indicated, the ability to provide air and ground expedited services to meet customers’ total transportation needs has been a key strategic objective for Roadrunner,” said Mark DiBlasi , president and CEO of Roadrunner. “Active Aero’s strong position in the marketplace is based upon the high quality of its service offering and personnel and its unique blend of expedited services. As a result, we believe Active Aero represents an ideal match with our strategy and an excellent platform for growth in expedited services globally.”

Active Aero reported total revenues of approximately $265m for the 12 months ending June 30, 2014. In March this year it was recognised as one of GM’s suppliers of the year.

Last month Roadrunner paid $13m for Integrated Services (ISI), an Indiana-based regional logistics provider focused on warehousing and transport services for the automotive industry.

That followed the acquisition of Rich Logistics in March this year for $48m, the same month in which it bought Unitrans International for $55.5m.
