FedEx Corp.’s retreat from handling packages for Amazon.com Inc. signals that the lines are being drawn in the battle over surging e-commerce shipments.
The end of two delivery contracts with Amazon means FedEx will have to make up for the lost sales by extending a push to serve other customers such as Walmart Inc. Amazon will have to rely more on United Parcel Service Inc. and the U.S. Postal Service as it seeks to fulfill a pledge for next-day delivery to top customers -- and build out its own shipping network.
