TDS (TDS) Q1 2026: Fiber Addresses Triple, Array Site Rental Revenue Jumps 64%

2026-05-08 | By EarningsIQ Research

TDS’s Q1 2026 marked a pivotal acceleration in fiber expansion and operational transformation, while Array’s tower business delivered robust site rental revenue gains and navigated legacy headwinds. The proposed full Array acquisition signals a strategic move to simplify structure and unlock capital flexibility, with both segments focused on margin improvement and disciplined investment as the year unfolds.

Summary

• Fiber Build Velocity Surges: TDS Telecom delivered a record first quarter in fiber address construction, nearly tripling YoY.
• Array Tower Revenue Accelerates: Site rental revenue climbed sharply, offsetting Dish non-payment and legacy cost drag.
• Strategic Simplification in Motion: Proposed Array buyout aims to streamline governance and enhance capital allocation agility.

Business Overview

TDS Inc. operates as a diversified telecommunications company with two principal segments: TDS Telecom, a regional broadband provider focused on expanding its fiber network to residential and business customers, and Array Digital Infrastructure, a tower infrastructure and spectrum monetization business. TDS Telecom generates revenue through broadband, video, and voice services, while Array’s income is driven by tower site rentals, spectrum sales, and partnership distributions. Fiber and tower infrastructure are the key growth engines, as legacy copper and cable revenue streams decline.

Performance Analysis

TDS Telecom reported a 3% decline in total operating revenues for Q1 2026, or 1% excluding divestitures, as strong fiber revenue growth and customer additions offset legacy copper and cable attrition. Fiber service address delivery nearly tripled YoY to 40,000, marking the highest first-quarter build in company history and bringing fiber to 58% of the total footprint. Residential fiber net adds rose 32% YoY, while fiber revenue increased 13%, helping to counteract a 10% drop in cable revenue and ongoing copper decline. Operational transformation initiatives, including system upgrades and process simplification, contributed to a 3% reduction in cash expenses.

Array Digital Infrastructure saw cash site rental revenue surge 64% year-over-year when normalized for Dish impact, with tenancy ratios improving sequentially. The tower business continues to benefit from the T-Mobile master lease agreement (MLA), while also managing the transition away from Dish Wireless, which ceased payments and was fully reserved against. Spectrum monetization progressed, with significant transactions closed or pending with T-Mobile and Verizon, and additional C-band assets positioned for future sale. However, legacy wind-down costs and property expense reclassification weighed on margins, with further cost takeout expected over time.

• Fiber Expansion Outpaces Legacy Decline: Fiber revenue growth now offsets most legacy losses, but total residential revenue still declined $5 million YoY due to divestitures and video attachment erosion.
• Operational Efficiency Gains: Transformation initiatives, including billing and field force modernization, are delivering early cost savings and improved customer experience.
• Array Monetization Momentum: Nearly 70% of spectrum holdings are now monetized or under contract, with further upside from C-band assets and partnership distributions.

Capital expenditures increased to $126 million in the quarter, reflecting the accelerated fiber build and internal construction investments. Both segments are executing against unchanged 2026 guidance, but TDS Telecom expects to trend toward the lower end of its revenue range due to persistent legacy headwinds.

Executive Commentary

Strategic Positioning

1. Fiber-Centric Transformation

TDS Telecom is aggressively shifting its business model to fiber, with 1.1 million addresses now served and 79% of its footprint gig-capable. The company is prioritizing contiguous market expansion, clustering, and copper-to-fiber conversions to drive scale and operational leverage.

2. Tower Platform Optimization

Array’s focus is on maximizing tenancy and cash flow from its existing tower portfolio, rather than pursuing new builds at unattractive economics. The company is also targeting cost reduction through land ownership initiatives and transitioning legacy operations to a leaner, tower-focused structure.

3. Spectrum Monetization and Capital Allocation

Array continues to opportunistically monetize spectrum, with major deals closed or pending and a disciplined approach to C-band sales. TDS’s acquisition proposal for Array aims to eliminate duplicative costs, enhance liquidity, and enable more flexible capital deployment across towers and fiber.

4. Operational Discipline and M&A

TDS is maintaining a disciplined approach to M&A, targeting small, accretive, fiber-rich tuck-ins like Granite State Communications, which add scale and support clustering strategies in adjacent markets without overextending capital commitments.

5. Customer Experience and Sales Execution

Investments in sales leadership, digital channels, and door-to-door distribution are driving improved fiber penetration, with pre-sales velocity in the low 20% range and expanding multi-dwelling unit (MDU) capabilities highlighted as future growth levers.

Key Considerations

This quarter underscores TDS’s dual-track strategy: scaling fiber to offset legacy declines while extracting value from tower and spectrum assets through disciplined execution and capital allocation. The proposed Array buyout is a structural pivot with long-term implications for governance and investment flexibility.

Key Considerations:

• Build Velocity as a Leading Indicator: Record fiber address delivery and robust construction pipeline are critical to future revenue growth and margin expansion.
• Legacy Drag Remains Material: Copper and cable declines continue to pressure top-line results, requiring sustained fiber outperformance and operational cost takeout.
• Array’s Tower Economics Improve: Ex-Dish, tenancy and site rental revenue trends are positive, but full margin normalization depends on further cost reduction and lease-up.
• Capital Allocation Flexibility: The proposed Array merger, if completed, would streamline structure and potentially unlock shareholder value, but execution risk and regulatory approvals remain.
• Spectrum and Partnership Optionality: C-band and partnership stakes provide future monetization levers, though timing and valuation are uncertain.

Risks

Persistent legacy revenue erosion, especially in copper and cable, remains a structural headwind until fiber penetration fully offsets declines. Execution risk in large-scale fiber deployment, including construction delays or cost overruns, could impact targets. Array faces uncertainties in further spectrum monetization, tenant churn, and ongoing Dish non-payment litigation, while the proposed merger’s success hinges on regulatory and shareholder approvals. Competitive intensity in broadband and tower markets, as well as emerging satellite threats, could pressure future growth and returns.

Forward Outlook

For Q2 2026, TDS reaffirmed guidance:

• TDS Telecom total revenues: $1.015B to $1.055B, trending toward lower half due to legacy headwinds
• Adjusted EBITDA: $310M to $350M
• Capital expenditures: $550M to $600M, supporting 200,000 to 250,000 new fiber addresses

For full-year 2026, Array’s guidance is unchanged:

• Total operating revenue, adjusted EBITDA, and OIDDA: Wide ranges maintained due to MLA and interim site timing

Management emphasized continued operational transformation, robust fiber construction pipeline, and cost discipline as key drivers for achieving these goals.

• Fiber build progress and customer conversion rates will be closely monitored
• Array’s focus on tower optimization and spectrum monetization remains central to margin improvement

Takeaways

TDS is executing a multi-year pivot to fiber and streamlined infrastructure ownership, with early signs of operating leverage and capital discipline. Investors should monitor build velocity, margin trends, and the outcome of the Array merger proposal as key drivers of long-term value realization.

• Fiber is now the engine of growth: With 58% of the footprint fibered and accelerating net adds, TDS is structurally shifting its revenue base.
• Array’s tower cash flow is stabilizing post-Dish: Site rental revenue growth and tenancy gains provide a foundation for future margin expansion.
• Merger execution and spectrum sales are the next catalysts: Successful integration and monetization will shape capital allocation and shareholder returns.

Conclusion

TDS’s Q1 2026 results highlight decisive progress in fiber expansion and tower monetization, but also reinforce the need for continued operational execution as legacy declines and integration complexities persist. The strategic simplification through the Array proposal and disciplined capital deployment position TDS for a more focused, growth-oriented future, contingent on sustained fiber momentum and successful transaction closure.

Industry Read-Through

TDS’s fiber build acceleration and Array’s tower revenue surge reflect broader industry trends of legacy-to-fiber transformation and tower cash flow optimization. Operators with contiguous market strategies and disciplined capital allocation are better positioned to offset legacy drag and compete against cable and satellite entrants. Array’s spectrum monetization and partnership cash flows provide a playbook for other infrastructure owners facing similar asset transition phases. The focus on lean operations, cost takeout, and digital sales channels is increasingly vital for regional broadband and tower players navigating competitive and technological disruption.
