Telephone and Data Systems, Inc (TDS) Stock Price & How to Invest

Telephone and Data Systems is a holding company that has spent the last two years dismantling and rebuilding itself. Its wireless business, UScellular, sold its operations and a large slice of spectrum to T-Mobile in a deal worth roughly $4.4 billion that closed in August 2025. What survived the sale is the infrastructure: about 4,400 cell towers, now housed in a separately listed entity called Array Digital Infrastructure, in which TDS holds roughly 81.9% of the equity and about 95.9% of the voting power. Alongside that sits TDS Telecom, the wireline segment, which passed one million marketable fiber service addresses and is building toward a target of about 2.1 million by 2028. Total revenue from continuing operations was roughly $309 million in the second quarter of 2026, with TDS Telecom contributing about $248 million of it.

The investment picture is a two-engine story. Engine one is fiber: TDS Telecom is spending heavily (2026 capital expenditure guidance around $625 million) to convert copper territories and expand into new markets, with residential fiber revenue growing roughly 13% while legacy copper and divested territories shrink the reported top line. Engine two is towers: Array signed a 15-year master license agreement with T-Mobile covering a minimum of 2,015 incremental towers plus an extension on roughly 600 where T-Mobile already sits, which turns the buyer of the wireless business into the anchor tenant of the tower business. Sale proceeds pushed net leverage below roughly 3.0x EBITDA and funded large one-time distributions. In May 2026 TDS proposed acquiring the Array shares it does not already own at an exchange ratio of 0.86 TDS shares per Array share, assuming Array first pays a dividend of about $10.40 per share, and Array's board formed a special committee to evaluate it. That proposal is currently the single biggest swing factor in the TDS structure.

Fiber is a capital-intensive business competing directly against cable incumbents and fixed wireless access from the same national carriers TDS now leases towers to, and overbuilt markets can see subscriber economics deteriorate quickly. Legacy copper and previously divested territories continue to shrink the reported top line, so headline revenue can fall even while the fiber business grows. Array's revenue is heavily concentrated in a single anchor tenant, which means the tower stream is only as durable as T-Mobile's network plans and the contract terms. The proposed Array buy-in is non-binding and subject to a special committee, so the exchange ratio can move, the deal can fail, or minority holders can litigate. TDS is also controlled through a voting-trust structure that gives insiders about 95.9% of Array's votes and comparable control at the parent, which limits outside shareholder influence over exactly these related-party decisions.

We give no verdict on Telephone and Data Systems, Inc. Both cases are real, which is why the question is contested at all, so here is the strongest version of each.

The case for buying. Fiber penetration, not fiber passings. TDS Telecom crossed one million marketable fiber service addresses and raised its 2026 delivery guidance to roughly 250,000 to 300,000 new addresses.

The case against. Fiber is a capital-intensive business competing directly against cable incumbents and fixed wireless access from the same national carriers TDS now leases towers to, and overbuilt markets can see subscriber economics deteriorate quickly.

A simple financial snapshot. These are approximations and refresh quarterly; for current figures see Telephone and Data Systems, Inc's investor relations page or your broker.

• Market cap: ~$4.1B
• Revenue (TTM, continuing ops): ~$1.2B
• Q2 2026 revenue: ~$309M (vs ~$299M a year earlier)
• Q2 2026 diluted EPS (continuing ops): ~$2.24
• Net leverage: ~below 3.0x EBITDA
• Dividend yield (trailing): ~0.45%

Reported revenue understates the fiber growth rate because divested territories and declining copper lines sit in the same line item. The Q2 2026 earnings figure is not a clean run rate either, since post-transaction accounting and one-time items dominate it. Analysts generally value TDS on a sum of the parts: a fiber network valued per passing or per subscriber, plus a tower portfolio valued on contracted rent multiples, less debt and the Array minority interest.

Other names that sit close to TDS: same theme, named as a direct competitor, or held beside it in the same funds. Each entry says which. Worth a look if you are thinking about diversification within a thesis rather than concentration on one ticker.

There are three common ways to get TDS exposure. Buy shares (or fractional shares) directly at any major broker. Hold an ETF that includes it, which spreads the position across many companies. Or build it into a focused thematic portfolio, so TDS sits alongside other stocks that express the same thesis.

Walnut takes the portfolio route. Describe a thesis where TDS fits (for example “AI infrastructure” or “dividend-growth large-caps”) and the AI proposes 5 to 6 constituents with target weights. You review the plan and fund it through your own broker when you're ready.

Post-transaction TDS is a fiber builder wrapped around a tower company, so the stock tracks fiber penetration economics and how the Array minority buy-in gets settled.

Whether TDS is worth buying today depends more on your time horizon and what you already hold than on any single call. We walk through valuation, what would have to go right, and the risks in is TDS a buy or a sell?, and where the stock could go from here in the TDS stock forecast.
