Fiber upside, tower risks, messy structure
- TDS changed shape after selling its wireless operations to T-Mobile on August 1, 2025.
- The main operating business is now TDS Telecom, which sells broadband, video, and voice service.
- Array owns 4,452 towers and spectrum licenses, including remaining spectrum not yet sold.
- TDS has proposed buying the public Array shares it does not own, using 0.86 TDS shares for each Array share.
- The story depends on fiber execution, closing the $1.0 billion Verizon spectrum sale, and resolving the DISH dispute.
A cleaner company, not yet simple
TDS is no longer the same company investors followed before 2025. After Array sold its wireless operations to T-Mobile, TDS became a holding company with two main pieces: TDS Telecom, a fiber-focused broadband provider, and Array, a tower and spectrum owner that TDS still does not fully own.
The bull case is that the pieces are easier to value now. TDS Telecom added 40,000 marketable fiber addresses in Q1 2026, its highest Q1 fiber build volume, and residential fiber net additions rose 32% year over year. Array has towers, spectrum, and a pending $1.0 billion spectrum sale to Verizon that could add more cash.
The bear case is that the cleanup is complicated. TDS proposed to buy the remaining public shares of Array at 0.86 TDS shares for each Array share, assuming Array pays a $10.40 special dividend first. That could simplify the structure, but the offer is non-binding and a special committee is reviewing it.
Finn's view is cautious because a lot must go right. The fiber build is real, but the stock still carries transaction risk, tenant concentration, a live DISH payment dispute, and uncertainty around how much cash the remaining spectrum will fetch.
Broadband cash and asset sales
TDS Telecom makes money by selling internet, video, voice, and related services to homes and businesses. The key push is fiber, which can offer faster internet and better service than older copper networks. Fiber growth is meant to offset declines in legacy voice, video, and copper services.
Array makes money by leasing space on its towers to wireless carriers and other tenants. As of March 31, 2026, Array owned 4,452 towers in 19 states and reported a tower tenancy rate of 0.96, excluding DISH Wireless because collection was viewed as unlikely.
Array also holds spectrum licenses. Spectrum is the right to use certain airwaves for wireless service. Some licenses are already under sale agreements, including the pending Verizon deal, while other remaining spectrum, mainly C-Band, still needs a buyer or another plan.
The model breaks if fiber spending does not turn into profitable customers, if spectrum sales are delayed or priced below hopes, or if major tower tenants do not pay. DISH has failed to make required payments since December 2023, so Array moved to cash-basis revenue recognition for that customer.
What TDS sells and owns
Residential fiber broadband
This is TDS Telecom's main growth push. In Q1 2026, residential fiber net additions were 10,900, up 32% year over year.
Legacy broadband, video, and voice
These services still bring in revenue, but many parts are shrinking. TDS Telecom reported total residential connections down 4% year over year in Q1 2026.
Commercial and wholesale wireline services
TDS Telecom sells business internet, voice, video, carrier access, and support-backed rural services. In Q1 2026, commercial and wholesale revenue both declined from the prior year.
Array tower leasing
Array leases tower space to carriers and other users. T-Mobile is now a key long-term tenant, which helps revenue but also raises customer concentration risk.
Spectrum licenses
Array holds licenses that can be sold or leased. The AT&T spectrum sale closed in January 2026 for $1.018 billion, while the Verizon sale is still expected to bring $1.0 billion if it closes.
Granite State Communications acquisition
TDS Telecom agreed to buy Granite State Communications in New Hampshire. The deal is expected to add about 11,000 fiber service addresses and close in Q3 2026.
Now a two-piece story
Mix is based on Q1 2026 continuing operating revenue from TDS's Form 10-Q. TDS Telecom was the largest revenue piece, while Array grew sharply after the tower agreement with T-Mobile, but Array revenue is concentrated.
What could go wrong
Array buyout stalls
High impact · Medium oddsTDS's proposal to buy the public Array shares is non-binding. A special committee is reviewing it, and there is no guarantee the deal is accepted or completed. A long process could keep investors focused on structure instead of operating results.
Verizon spectrum sale delayed
High impact · Medium oddsArray still expects the Verizon spectrum sale to bring $1.0 billion, but the deal needs regulatory approval and other closing steps. If it is delayed or fails, cash for debt reduction, investment, or shareholder returns could arrive later than hoped.
DISH payment dispute becomes permanent
Medium impact · High oddsDISH Wireless has not made required payments since December 2023. Array has stopped recognizing DISH revenue unless cash is received, and DISH site rental revenue was $6.5 million in 2025. The dollars are not huge for TDS as a whole, but the dispute shows that tower cash flows are not risk-free.
Fiber spend fails to pay back
High impact · Medium oddsTDS Telecom is spending heavily to build fiber. Q1 2026 capital expenditures at TDS Telecom were $126.0 million, more than double the prior year period. If new fiber homes do not convert into profitable customers, growth could consume cash instead of creating value.
Tower tenant concentration
Medium impact · Medium oddsT-Mobile is now a major tenant for Array after the wireless sale and tower lease agreement. That gives Array a long-term anchor, but it also means one customer can have a large effect on tower revenue. Interim tower leases can also be canceled by T-Mobile on a tower-by-tower basis.
In one breath
What does TDS do after selling UScellular's wireless business?
TDS now owns TDS Telecom and most of Array Digital Infrastructure. TDS Telecom sells broadband, video, and voice services, while Array owns towers and spectrum licenses.
What is Array Digital Infrastructure?
Array is the renamed former UScellular entity after the wireless operations were sold. It now leases tower space, holds spectrum licenses, and owns noncontrolling interests in some wireless-related companies.
Why does the Array buyout proposal matter?
TDS already owns most of Array, but public investors still own a minority stake. Buying the rest could make the company easier to understand and manage, but the proposal is not binding and may not close.
What is the biggest near-term catalyst for TDS stock?
The clearest near-term catalysts are progress on the Array buyout proposal and closing the $1.0 billion Verizon spectrum sale. A resolution of the DISH dispute would also help investor confidence in Array's tower revenue.
