Array Digital Infrastructure (AD) Q1 2026: Tower Site Rental Revenue Jumps 64% as Monetization, Fiber Expansion Accelerate

2026-05-08 | By EarningsIQ Research

Array Digital Infrastructure’s tower business delivered a 64% cash site rental revenue surge, offsetting legacy revenue declines and anchoring a period of structural transformation. TDS advanced its fiber-centric pivot with record address builds and a disciplined M&A approach, while both units navigated ongoing cost transformation and monetization of spectrum assets. Investors face a pivotal moment as TDS seeks to consolidate Array, aiming for long-term capital structure simplification and operational leverage.

Summary

• Tower Revenue Acceleration: Site rental growth and tenancy gains highlight Array’s operational leverage post-spin.
• Fiber Build Velocity: TDS Telecom’s record address delivery and net adds reinforce the fiber-centric pivot.
• Strategic Consolidation: TDS’s proposal to acquire Array targets cost and governance simplification for long-term value.

Business Overview

Array Digital Infrastructure (AD) operates two primary businesses: tower infrastructure, which generates recurring revenue through site rentals to wireless carriers, and spectrum monetization, involving the sale or lease of wireless spectrum licenses. Parent company TDS also owns TDS Telecom, a regional broadband provider focused on fiber network expansion and legacy cable/copper operations. Revenue streams are split between recurring infrastructure leasing and telecom subscriber services, with a growing emphasis on fiber and tower assets as legacy revenue streams decline.

Performance Analysis

Array’s tower business delivered a standout quarter, with cash site rental revenue up 64% year-over-year, driven by T-Mobile’s master lease agreement (MLA) and sequential tenancy growth after normalizing for the DISH contract dispute. Spectrum monetization continued with major transactions closing or pending, including sales to T-Mobile and Verizon, supporting substantial special dividends and future capital flexibility. The company’s guidance for tower revenue, EBITDA, and capex remains unchanged, but management flagged ongoing uncertainty tied to T-Mobile’s integration and interim site terminations.

TDS Telecom executed record fiber expansion, delivering 40,000 new marketable fiber addresses, nearly tripling last year’s first quarter pace. Residential fiber net adds rose 32% year-over-year, offsetting legacy copper and cable declines. However, total operating revenue declined 3% (or 1% excluding divestitures), as legacy revenue pressures outpaced fiber growth. Operating expenses fell 3% due to transformation initiatives, but adjusted EBITDA also dipped 3% given the revenue mix shift and investments in build capacity.

• Tower Revenue Outperformance: Array’s site rental revenue growth outpaced legacy headwinds, validating the tower-focused model post-spin.
• Fiber Build Execution: TDS’s record fiber address delivery and sales momentum signal operational scale and market opportunity.
• Legacy Drag and Cost Discipline: Declines in copper and cable revenue continue, but cost transformation and targeted M&A aim to stabilize and offset these trends.

Strategic capital allocation and operational discipline are now central to both businesses, as recurring tower and fiber revenues scale and legacy drag is methodically reduced.

Executive Commentary

Strategic Positioning

1. Tower Monetization and Tenancy Optimization

Array is laser-focused on maximizing tower asset utilization, driving sequential tenancy gains (excluding DISH) and robust application volumes. Management is actively working to reduce negative cash flow assets through ground lease optimization and selective decommissioning, with a multi-year plan to improve tower cash flow margins.

2. Fiber-Centric Transformation at TDS Telecom

TDS is aggressively scaling its fiber footprint, with 1.1 million service addresses now representing 58% of the total base and 79% gig-capable. The company’s clustering and edge-out strategies target adjacent markets for expansion, prioritizing high-return builds and operational synergies. The Granite State Communications acquisition adds 11,000 contiguous fiber addresses, reinforcing this approach.

3. Spectrum Monetization and Capital Reallocation

Spectrum sales remain a key capital unlock, with roughly 70% of holdings monetized or under contract. Special dividends and asset sales provide liquidity for reinvestment in core fiber and tower operations. Management continues to view C-band spectrum as a valuable long-term asset, with no urgency to sell below fair value.

4. Cost Transformation and Operational Efficiency

Both businesses are executing on cost-reduction roadmaps, with TDS targeting $100 million in run-rate savings by 2028. Early benefits are flowing through, though much will be offset by inflation and reinvestment in growth. Array’s focus on land ownership and maintenance cost reduction aims to structurally improve tower margins.

5. Corporate Simplification and Strategic M&A

TDS’s proposal to acquire Array’s minority shares would eliminate duplicative costs, streamline governance, and increase capital flexibility. The deal structure is designed to be tax-efficient and maintain exposure to both tower and fiber growth for current Array shareholders. TDS’s M&A strategy remains focused on small, accretive, fiber-centric tuck-ins that support clustering and operational leverage.

Key Considerations

This quarter marked an inflection in operational execution, with Array’s tower model delivering scale and TDS Telecom’s fiber pivot gaining momentum. The proposed consolidation of Array under TDS’s umbrella is a pivotal move to unlock synergies and long-term value, but also introduces governance and integration complexity.

Key Considerations:

• Monetization Pipeline: Spectrum transactions and special dividends continue to drive near-term capital availability and shareholder returns.
• Fiber Growth vs. Legacy Drag: Fiber revenue is scaling, but legacy cable and copper declines remain a headwind; execution on address builds and sales conversion is critical.
• Cost Transformation Impact: Early cost savings are visible, but much of the $100 million target will be reinvested or offset by inflation as the footprint expands.
• Governance and Integration Risks: The TDS-Array consolidation proposal must navigate special committee review, shareholder approval, and integration of two distinct business models.
• Market Positioning: Both businesses are positioning for secular fiber and tower demand, but face competition, technology shifts, and evolving carrier strategies.

Risks

Key risks include ongoing legacy revenue attrition, especially in copper and cable, which could outpace fiber growth if execution falters. Array’s tower revenue is exposed to carrier consolidation, contract disputes (as with DISH), and site churn from T-Mobile integration. The proposed TDS-Array merger introduces approval and integration risk, while spectrum monetization is subject to regulatory and market timing uncertainty. Competitive intensity in both fiber and tower markets, as well as emerging satellite technologies, could pressure future growth and margins.

Forward Outlook

For Q2 2026, the company guided to:

• Unchanged tower and telecom revenue, EBITDA, and capex ranges
• 200,000–250,000 new fiber service addresses targeted for full-year 2026

For full-year 2026, management maintained guidance:

• Telecom revenue: $1.015–$1.055 billion; Adjusted EBITDA: $310–$350 million; Capex: $550–$600 million

Management highlighted several factors that will shape results:

• Legacy headwinds in copper and cable markets guiding toward the lower end of revenue range
• Continued cost transformation and efficiency gains expected to support margins

Takeaways

Investors should track execution on fiber build velocity, tenancy gains in the tower portfolio, and the pace of spectrum monetization as the primary levers for value creation. The proposed TDS-Array consolidation is a structural pivot, with potential for cost and capital synergies but also integration and approval hurdles.

• Fiber and Tower Execution: Operational momentum in fiber builds and tower tenancy is critical to offsetting legacy drag and capitalizing on secular growth.
• Capital Flexibility: Spectrum monetization and special dividends provide near-term liquidity, but long-term value depends on recurring revenue scaling and margin improvement.
• Strategic Clarity: The consolidation proposal, if completed, could simplify the capital structure and unlock new avenues for capital allocation and operational leverage.

Conclusion

Array and TDS Telecom are both executing on transformation roadmaps, with tower revenue and fiber build velocity as clear bright spots. The pending consolidation proposal is a major strategic swing, with the potential to accelerate simplification and capital deployment if executed successfully.

Industry Read-Through

Array’s tower revenue acceleration and tenancy gains signal continued carrier demand for neutral-host infrastructure, even as legacy contracts unwind and wireless consolidation reshapes the landscape. TDS’s fiber-centric growth strategy and clustering M&A approach reflect broader industry trends toward regional scale and operational leverage in broadband, with legacy cable and copper declines reinforcing the urgency of transformation. Spectrum monetization remains a key capital lever for infrastructure players, but regulatory timing and asset scarcity will continue to influence deal flow and valuation across the sector. Investors in both fiber and tower assets should monitor execution on build velocity, tenancy optimization, and capital recycling as core drivers of long-term value.
