Hub Group is expanding its refrigerated intermodal capabilities by acquiring the intermodal assets of Marten Intermodal. This move makes Hub Group the second largest provider of temperature-controlled intermodal solutions in North America, according to the company.

Temperature-controlled intermodal transportation gives shippers reliable service and lower costs than over-the-road temperature-controlled transportation, Hub Group noted.

In an investor presentation, the company said Hub Group’s refrigerated intermodal volume has outperformed through the cyclical downturn and reflects healthy shipper demand.

In addition, refrigerated intermodal pricing and margin per load are higher than non-temperature-controlled equipment, and Hub Group’s full refrigerated fleet is currently in service.

Hub Group's Deal With Marten

Marten Transport has operated its Intermodal business since 2005 and serves over 100 customers. It provides refrigerated intermodal service to a diversified group of shippers in food and beverage end markets, without significant overlap with Hub Group.

The acquisition includes approximately 1,200 refrigerated containers.

“We are excited to more than double Hub Group’s temperature-controlled container fleet and leverage our existing intermodal network to serve Marten Intermodal’s customers,” said Phil Yeager, Hub Group’s president and CEO, in a release.

The company said it expects operational synergies through additional scale and network density, and cross-sell opportunities with additional refrigerated customers across business lines.

Marten Intermodal generated $51.5 million of revenue over the trailing 12 months ended June 30, 2025

The transaction is structured as an asset purchase of certain intermodal equipment and contracts from Marten Transport Ltd. for $51.8 million in cash and is expected to close by the end of the third quarter, subject to certain customary closing conditions.
