XPO Logistics specializes in third party logistics (3PL) but doesn't own any ships, planes, or trucks. Customers' freight is transported throughout the US by independent contractors, who give the company's expedited freight forwarding unit access to a fleet of vehicles that includes cargo vans, trucks, and tractor-trailers. XPO offers domestic and international freight forwarding services as well as truckload freight brokerage service to more than 50,000 customers across the US, Canada, Mexico, Asia, and Europe. The company has experienced massive revenue growth over the years due to acquisitions.
