TDS leans into fiber and towers, but the market remains unconvinced
Record fiber address delivery and Array's spectrum windfall weren't enough to reverse a 27% drawdown — legacy revenue pressure and an open tender cloud the story.

Transformation in motion
Telephone & Data Systems (TDS) headlined its Q2 2026 report with record fiber service address delivery — 66,000 addresses, up more than 2.5x year-over-year — and a flurry of spectrum monetization at its tower subsidiary Array Digital Infrastructure. Yet the market remains skeptical: the stock sits 27% below its February high, dragged by persistent legacy revenue stream declines at the legacy telecom business and an open tender to acquire the remaining ~18% of Array.
The transformation is stark: total revenue fell 73% year-over-year to $309M, largely a function of the sale of the former UScellular wireless operations. But within that shrinkage, there are clear growth vectors. TDS Telecom delivered a record pace of fiber builds, powered by the federal E ACAM market program, while Array grew cash site rental revenue 65% year-over-year (ex-DISH) and lifted its margin guidance.
“We believe the cost of maintaining that spectrum by building it out is very reasonable relative to the overall value of it.” — Anthony Carlson, Array President & CEO
Fiber: building faster, still bleeding legacy
Ken Dixon, TDS Telecom President, cited “the strongest first half delivery in company history” — Kenneth Dixon, Executive or Senior Management (likely COO or similar) based on operational updates · 2026-08-07 with ~106,000 fiber service addresses added. Management raised the full-year build target to 250–300k addresses and increased capital expenditure guidance to $625–675M. The company is leveraging E-ACAM subsidies to push fiber into rural copper markets, converting legacy customers and adding new ones.
But the legacy tail persists. “residential fiber revenue growth of 13% in the quarter” — Kristina Bothfeld, Senior Finance Executive (likely CFO or similar) involved in financial guidance and reporting · 2026-08-07 is helping offset copper and cable declines, but overall telecom revenue guidance was lowered due to those pressures. The result: Total revenue fell to $309M from $1.15B a year ago, while free cash flow turned deeply negative as build capital ramps.
Array: monetizing the balance sheet
Array’s tower business is gaining traction. The tenancy ratio improved to 0.98, and the company closed $1.2B of spectrum sales with T-Mobile and Verizon in the quarter, monetizing ~70% of its non-C-band holdings. Management raised OIBDA and adjusted EBITDA guidance, citing higher T-Mobile interim revenue and lower operating expenses. “cash site rental revenue increase 65% versus Q2 of last year” — Anthony Carlson, Executive focused on tower operations and spectrum monetization (likely CEO or President) · 2026-08-07 demonstrates the underlying growth.
With the C-band still in hand, Array is in no rush. “We have no specific process update,” but the posture is opportunistic. The balance sheet is solid—Effective net cash stands at $698M, up 119% year-over-year—and the company has ample room to fund its growth.
Capital allocation overhang
The biggest overhang is the pending TDS offer to acquire Array’s minority interest. TDS is restricted from buying back its own stock while the offer is outstanding. “We were not in the market for our share buyback program,” — Vicki Villacrez, Senior Executive involved in M&A and financial strategy (likely CFO or similar) · 2026-08-07 said Vicki Villacrez, adding that the $520M authorization remains. This restraint was flagged in prior calls: “We are not going to comment on any impact or implications of the offer on the table” — Vicki L. Villacrez, Executive · 2026-05-08 — a message the company has repeated quarter after quarter.
The market’s drawdown likely reflects uncertainty around the deal’s terms and the combined company’s future. Investors want proof that the fiber build yields margin expansion and that Array’s spectrum windfall is not a one-off.
Investment take
TDS is in the midst of a deliberate pivot from legacy wireless and copper to a fiber-first telecom and a pure-play tower company. The execution so far is commendable—record build pace, strong tower tenancy, and a fortified balance sheet. But the legacy revenue pressure and the capital intensity of the fiber build are weighing on near-term profitability. The stock’s 27% drawdown reflects that tension.
The next catalysts are the resolution of the Array tender, continued E-ACAM delivery, and evidence that legacy declines are being offset by fiber and tower growth. If the transformation continues on this trajectory, the current pessimism may prove overdone—but the market is demanding more proof.
