TDS Q2: 15,000 Fiber Adds Help, but 6% Revenue Slide Keeps the Stock in the Balance

Q2 results improved, but the recurring engine still looks weak

TDS posted Q2 diluted EPS of $2.24, but that result was significantly supported by a $409.8 million spectrum-sale gain at Array. Management was clear that the swing to profit mainly reflected that one-time gain rather than recurring operations. The headline number looked strong; the underlying business did not.

That changes the scorecard. Array has now completed transactions to monetize virtually all of its spectrum outside of the C-Band, so future results will have to rely more on recurring business performance. Bulls can still point to cash site rental revenue up 65% at Array and argue the fiber build deserves time. Bears have the cleaner near-term argument: telecom revenues still fell, and legacy declines continued to offset fiber gains.

Without the spectrum windfall, the real test is recurring demand, pricing, and cash conversion. If the core businesses cannot hold up on their own, the stock is still carrying old strength into a new phase.

TDS Telecom's fiber build is scaling, but demand still has to justify the spend

The key question is not whether TDS is laying fiber. It is whether the expanding footprint is converting into customers quickly enough to support the investment.

The footprint is getting bigger

TDS Telecom added approximately 66,000 marketable fiber service addresses in the quarter. Management also highlighted that Q1 and Q2 represented the strongest first half in company history for fiber delivery. That shows the buildout is moving with purpose.

Customer adds are improving, which matters

TDS reported 15,100 residential fiber net additions, up 47% year over year. Residential revenue per connection also increased 1% year over year. Those figures suggest demand is improving rather than simply following the pipe.

The catch remains the broader income statement

This is still not a clean recovery story. Quarterly Capital expenditures (TDS Telecom): totaled $179 million in the quarter, and broader results showed accelerated fiber construction significantly pressured free cash flow. At the same time, TDS Telecom experienced a 6% revenue decline and an operating loss as legacy service erosion offset fiber gains. So the central debate remains unresolved: customer growth is becoming more credible, but it has not yet fully offset legacy decay and the cash cost of expansion.

What would confirm the story

• Residential fiber net adds stay near or above 15,100.
• Revenue per connection remains stable or improves.
• Fiber growth continues to offset legacy declines rather than merely slow them.

What would still fail the test

• Telecom revenue keeps falling while construction spending stays elevated.
• Cash flow remains pressured without faster customer conversion.
• The company adds addresses faster than it adds paying customers.

Array remains the clearer operating strength

Array is the part of the business that currently looks most like a standard infrastructure growth story. It operates over 4,400 cell towers, and its cash site rental revenue up 65% year over year points to healthy tenant demand. Management also raised Array's full-year adjusted OIBDA and adjusted EBITDA guidance, reinforcing that the tower business is not just stabilizing but improving.

Why Array matters more now

Array has now completed transactions to monetize virtually all of its spectrum outside of the C-Band, and that activity helped the quarter's financial results. The company also pointed to substantial cash inflows and special dividends. That is helpful in the short term, but it also raises the importance of what comes next: can Array keep creating value through operations and cash generation once the easiest spectrum deals are done?

Where the debate remains

This is still not a fully simple story. Array's operating strength is real, but investors still have to weigh the impact of the non-binding proposal was made for TDS to acquire all outstanding Array shares not already owned. Structure and ownership clarity matter because they affect how much of Array's value can be credited to repeatable performance versus one-time simplification.

What decides the next move for TDS stock

The stock now sits between two narratives. If recurring performance improves, it can start to look like patient compounding. If not, the market may keep treating it as a collection of assets helped by one-time gains and ongoing restructuring.

What would support a re-rating

• Fiber adds and footprint growth turn into steadier recurring revenue.
• Array keeps building operating value after the major spectrum monetizations.
• The company shows that spending on expansion does not keep drowning the cash story.

What would keep the stock stuck

• Telecom revenue and profitability continue to weaken.
• Cash flow stays pressured for multiple quarters.
• The Array ownership debate remains unresolved.

If the operating follow-through shows up, patience could pay off. If not, the stock may remain trapped between short-term cash events and a longer-term recovery that still needs proof.
