Transportation and technology companies dominate the top 10 spots on the list of the Top U.S. Postal Service Suppliers for FY 2015.  Federal Express Corporation again tops the list, a position it has held since 2002. Overall, the Postal Service spent $12.5 billion on outside purchases, about half of it on transportation.

FedEx, now in the third year of a seven-year air cargo network contract, received nearly $1.4 billion in revenue, a 3 percent drop from last year. Package giant United Parcel Service is also among the agency’s top suppliers, earning $154 million in postal revenues and moving up from No. 12 to No. 11.

Other transportation-related companies in the top 10 include trucking company Salmon Companies, Inc. (No. 4, $229 million); Victory Packaging, logistics and distribution services provider for ReadyPost and other packaging supplies programs (No. 5, $212 million); commercial airline United Airlines, Inc.

Not far behind are trucking company Eagle Express Lines, Inc., No. 12 ($140 million); cargo airline Kalitta Air, LLC, No. 15 ($97 million); and commercial airline Delta Air Lines, Inc., No. 16 ($93 million).

Technology-related companies on the list start with EnergyUnited Electric Membership Corporation, which provides telecommunication and energy billing services. EnergyUnited is again the Postal Service’s second-largest supplier with $440 million in revenue, most of which is paid out to other companies. At No. 3 is Honeywell International, Inc., which received $273 million under its contract to provide 225,000 Mobile Delivery Devices (MDD). Letter carriers use the MDD to scan mail and packages.

HP Enterprise Services, LLC, a provider of computer equipment, ranks No. 7 with $192 million in revenue, about $20 million more than last year. Accenture Federal Services, which provides enterprise technology and consulting services to the agency, is ranked No. 8 with $188 million. International Business Machines Corporation (IBM) and AT&T Corporation again placed in the Top 20. EMC Corporation, which recently won a Postal Service contract to provide information storage and management services, has already cracked the Top 20 with $81 million in postal revenue.

Rounding out the Top 10 with $159 million in revenue is Northrop Grumman Corporation, which operates the Postal Service’s central repair facility in Topeka, Kansas.
