Indianapolis-based Celadon Group’s Celadon Trucking Services subsidiary has agreed to acquire Warren-based Rock Leasing Inc. in northeast Indiana and Wadley, Alabama-based Kelly Logistics Inc.

Acquisition of the two trucking companies will expand Celadon’s footprint and add temperature-controlled service to its specialties, according to a report in the Indianapolis Business Journal. Terms of the deal were not disclosed.

Rock Leasing is a leading provider of temperature-controlled shipments in the Midwest. Celadon plans to maintain Rock’s 20-acre leasing facility in Huntington County, IN, that includes 150,000 sq. ft. of warehouse space. Kelly Logistics offers dedicated customer spotting and shuttle services in the Southeast.

“Based on previous acquisitions, we believe we can actually enhance that service through upgraded equipment, advanced technology, additional assets available for dispatch, and an industry leading safety record,” Celadon CEO Paul Will said in a prepared statement.

Celadon has made more than a dozen acquisitions in as many years — typically small, privately held carriers.

Last week Celadon Group Inc. said it plans to build a $5.25 million driver-training center and add 182 workers to its 633-employee Indianapolis work force by 2016, according to the Indianapolis Business Journal report.
