Knight-Swift is the largest truckload carrier in the US, with a diversified transportation offering. Pro forma for the U.S. Xpress deal, about 82% of revenue derives from Knight's asset-based trucking business, with full truckload (for-hire dry van, refrigerated, and dedicated contract) making up 69% and less than truckload at 13%. Truck brokerage and other asset-light logistics services make up 9% of revenue, with intermodal near 6%. Knight's intermodal operations use the Class I railroads for the underlying movement of its shipping containers and include drayage (regional trucking services to and from inland intermodal ramps/terminals). The remainder of revenue reflects services offered to shippers and third-party truckers, including equipment maintenance and leasing.
