As part of our postal industry practice, we annually compile a list of the Top 150 USPS suppliers based on data received under the Freedom of Information Act.

In FY 2017, USPS spent $13.9 billion on outside purchases and rental payments, an increase of $181 million over last year.  The biggest increase went to the top 10 USPS suppliers. That group received a total of $3.9 billion, up $400 million from last year and accounting for 28 percent of the Postal Service’s total spend. The Top 150 suppliers received $9.2 billion, about two-thirds of the agency’s total spend. Only 81 suppliers collected revenues exceeding $25 million in 2017.

As it has since 2002, Federal Express Corporation lands atop the list, this year with $1.61 billion in revenues—about a $68 million drop from its 2016 earnings. FedEx carries package and letter mail for the Postal Service. FedEx’s air cargo network contract with the Postal Service has been extended several times, and the latest extension takes it to September 29, 2024.

Federal Express Corporation was the U.S. Postal Service’s largest contractor in fiscal year 2013. The next largest USPS supplier was EnergyUnited, which provides consolidated telecommunication and energy billing services. Military air mail transportation provider Kalitta Air was third. Six of the Postal Service’s top 10 suppliers served the agency’s transportation needs. The Top 150 USPS supplier list is compiled annually by David P. Hendel, a partner in Husch Blackwell LLP’s Government Contracts practice group who focuses on Postal Service contracting matters.
