United Parcel Service

RANK43

Big Brown continued its reign as America’s leading delivery business even as it slipped two spots, to No. 43, on this year’s list. UPS's revenues rose 3.1%, to $74.1 billion, in 2019, keeping it ahead of perennial rival FedEx. But another threat looms. While FedEx cut ties with Amazon, UPS has hitched its signature brown wagons to the retailer-rocket ship, relying on it for growth. Still unclear is how that alliance will fare as Amazon doubles down on a delivery network of its own. Though UPS will benefit from increasing demand for store-to-door package service amid the coronavirus pandemic, the shipper's new CEO, Carol Tomé, will have to keep an eye on what may turn out to be a tricky coopetition arrangement with mighty Amazon.
