Telephone And Data Systems — Key Risks
TDS Has Sold Its Core Wireless Business and Is Now Winding Down a Much Smaller Operation
TDS completed the sale of its primary wireless business (operated under the name "Array") to T-Mobile on August 1, 2025. What remains is a significantly smaller company — mostly cell towers, some wireless spectrum licenses, and minority stakes in certain wireless companies. This dramatic shrinkage brings major restructuring costs, severance payments, advisory fees, and uncertain decommissioning expenses for towers that T-Mobile chooses not to keep using.
Array's Tower Business Is Now Almost Entirely Dependent on T-Mobile
After the T-Mobile deal closed, Array signed a Master Lease Agreement (MLA) under which T-Mobile commits to lease space on Array towers for a minimum of 15 years. That sounds stable, but it also means Array's tower revenues are now overwhelmingly tied to one customer. If T-Mobile fails to meet its lease obligations, Array — and by extension TDS — would be severely impacted with very little diversification to fall back on.
Pending Spectrum Sales to Verizon and T-Mobile Could Fall Apart
Array is in the process of selling wireless spectrum licenses (the radio frequencies used to transmit data) to both Verizon and T-Mobile. These deals require regulatory approval and other conditions to close. If they don't go through, TDS loses the expected cash proceeds needed to pay down debt or return capital to shareholders. Worse, Array still holds spectrum with FCC build-out requirements it hasn't fully met — meaning it could face penalties or even license forfeiture if it can't find a buyer or a carrier to operate the spectrum on its behalf.
DISH Wireless Is Disputing Its Lease Obligations to Array
In September 2025, DISH Wireless sent Array a letter claiming its payment obligations under its Master Lease Agreement are excused due to FCC actions and spectrum sale agreements. This is a direct revenue threat — if DISH successfully avoids its contractual commitments, Array collects less tower lease income than expected.
TDS's Wireline Business Faces an Expensive Fiber Build With Execution Risk
TDS's remaining core operating business, TDS Telecom, is spending heavily to build out fiber broadband networks. This requires permits, third-party contractors, utility access, and precise project management. Supply chain disruptions, labor shortages, and cost overruns are all real risks. Delays could weaken TDS's competitive position in its markets and force write-offs of already-deployed capital.
Government Funding That Supports TDS Telecom Could Be Reduced or Eliminated
TDS Telecom receives meaningful financial support from programs like the Connect America Fund (CAF) and related FCC programs to build networks in rural "high cost" areas. These programs come with build-out deadlines and compliance requirements. If TDS misses those requirements, it faces penalties and loss of support payments. There is also no guarantee these programs continue at current funding levels, which would directly harm TDS Telecom's economics in rural markets.
A Voting Trust Controls TDS and Limits Outside Investors' Influence
A TDS Voting Trust — which holds most of the high-vote Series A Common Shares (10 votes per share) — controls approximately 56.7% of general voting power and elects a majority of the board. This structure makes a takeover or activist pressure essentially impossible without the trust's cooperation. The trust is set to expire in June 2035. For ordinary shareholders, this means limited ability to influence company direction or benefit from a potential acquisition premium.
