FedEx is ending its ground delivery partnership with Amazon, FedEx said on Wednesday, news that comes as Amazon moves to expand its own delivery network.

“This change is consistent with our strategy to focus on the broader e-commerce market, which the recent announcements related to our FedEx Ground network have us positioned extraordinarily well to do,” FedEx said in a statement.

{mosads}Reuters reported that FedEx was ending its contract with Amazon for small-package ground deliveries following its decision not to renew its cargo delivery contract with Amazon. 

Amazon, meanwhile, has been expanding its delivery fleet of vans, trucks and planes. The online retail giant made up less than 1.3 percent of FedEx’s revenue last year, according to Reuters. 

“We are constantly innovating to improve the carrier experience and sometimes that means reevaluating our carrier relationships,” Amazon said in a statement. “FedEx has been a great partner over the years and we appreciate all their work delivering packages to our customers.”
