FedEx pioneered overnight delivery in 1973 and remains the world's largest express package provider. In fiscal 2025, the firm's Federal Express segment—which houses the core package delivery operations—made up 86% of total revenue, with 10% coming from FedEx Freight, its asset-based less-than-truckload shipping segment.

FedEx acquired Dutch parcel delivery firm TNT Express in 2016, boosting its presence across Europe. TNT was previously the fourth-largest global parcel delivery provider.
