TDS

Telephone and Data Systems, Inc.

A company behind two U.S. telecom businesses: TDS Telecom delivers fiber broadband, video, voice, and wireless to more than a million connections in 30 states, while Array ranks among the nation's largest tower operators, leasing thousands of towers to T-Mobile, AT&T, and Verizon. In 2025, Array sold its wireless operations to T-Mobile and signed deals to sell more spectrum to Verizon and AT&T. TDS is a 'controlled company,' with the TDS Voting Trust holding most of its voting power.
