"FedEx has made the strategic decision to not renew the FedEx Express US domestic contract with Amazon.com, 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 Amazon.com and other FedEx business units or relating to international services," according to the release. 

Amazon constituted less than 1.3% of FedEx's revenue for the 12-month period ended December 31, 2018. 

In February, shares of UPS and FedEx took a hit after Amazon announced the launch of a "Shipping with Amazon" service that will entail picking up packages from businesses and shipping them to consumers, according to the Wall Street Journal, which cited unnamed sources familiar with the matter (ie AMZN's comms department).
