On October 19, 2021, we acquired 100% of the equity interests of Choptank Transport, LLC (“Choptank”). Total consideration for the transaction was $127.6 million in cash and the settlement of accounts receivable due from Choptank of $0.3 million. In connection with the acquisition, we granted approximately $22 million of restricted stock to Choptank's owners and senior management team, which is subject to certain vesting conditions.

The acquisition of Choptank enhanced our refrigerated trucking transportation solutions offering and complemented our growing fleet of refrigerated intermodal containers. Choptank has developed a proprietary technology platform that we will leverage to enhance our truck brokerage service line.
