FedEx has elected not to renew one of its contracts with Amazon for their Express overnight and two-day service.

“FedEx has made the strategic decision to not renew the FedEx Express US domestic contract with, Inc. as we focus on serving the broader e-commerce market,” the company said in a Friday statement.

Of note, the decision “does not impact any existing contracts between and other FedEx business units or relating to international services,” according to the release.
