Founded in 1979, AIT is a Chicago, based provider of transportation management services. The target specializes in air and sea freight, ground distribution, warehouse management, intermodal and third party logistics. AIT serves a variety of markets such as the government, life sciences, perishables, residential delivery and retail logistics sectors.

“Over the past 35 years, AIT has developed a sterling reputation in transportation and logistics, a core area of specialization at Quad-C,” states Quad-C partner Tom Hickey. “We are excited to assist AIT and support the company’s next stage of expansion.” Financial terms of the investment were not disclosed.

Quad-C, based in Charlottesville, Virginia, backs companies generating $75 million to $400 million in revenue. The middle-market private equity firm has invested more than $3.9 billion in capital across all funds since its start in 1989.

Quad-C raised its ninth investment fund in March, securing approximately $1.1 billion in capital commitments. The firm has made numerous deals in the past, including: the purchase of carpet manufacturer Stanton Carpet Corp. from Norwest Equity Partners; the completed acquisition of Rainbow Early Education Holding LLC from Spire Capital Partners; and the backing of Inmark Packaging.
