TDS at Citi’s 2025 Conference: Fiber Focus and Spectrum Sales

Telephone and Data Systems (TDS) and its now-separate subsidiary Array Digital Infrastructure outlined ambitious growth and capital return strategies at Citi's 2025 TMT Conference. Array, established as the fifth-largest tower company, expects $1 billion spectrum sales each to AT&T and Verizon, with proceeds funding special dividends, alongside a projected 50% increase in cash revenues from T-Mobile colocations. Meanwhile, TDS Telecom plans to double its fiber footprint to 1.8 million addresses in five years, supported by its EACAM program and new mobile offering, anticipating rising capital expenditures before achieving positive free cash flow. Both companies are prioritizing operational efficiencies, including AI integration, to drive margin improvement and enhance shareholder value through their respective strategic transformations.

Analysis

Telephone and Data Systems (TDS) is executing a significant strategic pivot, bifurcating its operations into two distinct entities: a high-growth fiber company, TDS Telecom, and a value-oriented tower operator, Array Digital Infrastructure. Array is positioned for substantial near-term capital returns, underpinned by two pending $1 billion spectrum sales to AT&T and Verizon, with proceeds earmarked for special dividends. The AT&T sale is anticipated to close by year-end 2025, pending FCC approval. Operationally, Array's colocation revenue grew 12% in Q2, and it projects cash revenues will increase by approximately 50% following the integration of 2,015 committed colocations from T-Mobile. The company's transition to standard tower company reporting metrics, such as AFFO and adjusted EBITDA, in Q3 will be critical for peer valuation, though investors must account for temporary wind-down and start-up costs.

Contrasting this, TDS Telecom presents a long-term, capex-intensive growth story. The company plans to double its fiber footprint to 1.8 million addresses within five years, accelerating from 150,000 new addresses this year to 200,000 next year. This expansion, supported by a $90 million annual revenue stream from the EACAM program, will drive an increase in capital expenditures and a near-term drag on free cash flow. However, the consolidated TDS entity maintains a low leverage ratio of approximately 1.5x, providing significant balance sheet flexibility for this buildout and potential synergistic M&A. Management anticipates meaningful long-term margin improvement driven by the efficiency of its fiber network and the launch of its TDS Mobile MVNO, which is designed to reduce customer churn, while dismissing fixed wireless and satellite as material long-term threats.

Key Decisions for Investors

• Investors should evaluate the company as a sum-of-the-parts story, weighing Array's near-term shareholder returns from spectrum sales against TDS Telecom's long-term, capital-intensive fiber growth narrative.
• Monitor for the successful FCC approval and closing of Array's $1 billion spectrum sale to AT&T by year-end, as this is the primary catalyst for an anticipated special dividend.
• For TDS Telecom, the key focus should be on execution of its fiber buildout, tracking progress towards its 1.8 million address goal and penetration rates, while accepting a period of elevated capex and suppressed free cash flow.
• The upcoming Q3 earnings call will be a crucial event, providing the first clear look at Array's performance with tower-specific metrics like AFFO and offering updated guidance on TDS Telecom's accelerated investment plans.
