How many companies does ups own?

As of my last update in October 2023, UPS (United Parcel Service) operates several subsidiaries and owns various companies to enhance its logistics and delivery services. Notably, it owns UPS Airlines, UPS Freight, and several other specialized logistics and supply chain management companies. However, the exact number of companies under its ownership can vary due to acquisitions and divestitures, so it's best to refer to their latest financial reports for the most accurate count.
