## Overview

Array Digital Infrastructure, Inc. is a U.S.-based tower infrastructure company that earns revenue by leasing space on its communications towers and by providing related ancillary services. The company owns 4,450 towers across 19 states and describes itself as the fifth largest tower owner and operator of shared wireless communications infrastructure in the United States. Its portfolio supports 5G and other wireless deployments, and Array’s history as a former wireless carrier gives it operating insight into tenant needs and site economics. As of December 31, 2025, Array is also an 82.0%-owned subsidiary of Telephone and Data Systems, Inc. The company’s business has shifted away from providing wireless communication services, which were disposed of on August 1, 2025, leaving Array focused on tower colocation and spectrum monetization.

## Customers

Array’s core customers are wireless network operators that lease tower space to place antennas and other equipment on its sites. The company specifically highlights Verizon, AT&T, and especially T-Mobile as major tenants, and it also serves DISH Wireless under a contractual arrangement. Beyond large carriers, Array targets internet service providers, government and public safety agencies, broadcast and media companies, and other businesses that need elevated communications sites. Customer demand is driven by mobile data growth, 5G build-outs, spectrum deployment, and the need for additional coverage in rural, suburban, and urban areas. Because a substantial portion of revenue comes from a small number of tenants, customer concentration is a defining feature of the business model.

- **Large wireless carriers** (primary) — Lease tower space for macro network equipment and drive most of Array’s site rental demand, especially T-Mobile.
- **DISH Wireless** (primary) — Uses Array tower sites under a contractual commitment, but has disputed some obligations and missed certain payments.
- **Internet service providers** (secondary) — Buy tower access to extend broadband and wireless coverage where elevated sites improve network reach.
- **Government and public safety** (secondary) — Lease tower space for mission-critical communications coverage and resilience.
- **Broadcast and media** (secondary) — Use tower locations for transmission infrastructure and signal distribution.

- Large wireless carriers such as T-Mobile, Verizon, and AT&T
- DISH Wireless under a long-term lease commitment
- Internet service providers needing tower access for network expansion
- Government and public safety agencies using tower sites for communications
- Broadcast and media companies requiring elevated transmission locations
- Other businesses that need colocation on existing tower infrastructure

## Geography

Array’s business is concentrated in the United States, where it owns 4,450 towers across 19 states. Its tower portfolio includes attractive rural, suburban, and urban locations, and the company emphasizes that more than one-third of its towers have no competing structure within a two-mile radius. Geography matters because tower economics depend on local coverage gaps, population density, and the ability to add tenants to existing sites. The company also manages ground leases and site rights at the tower level, so local property terms directly affect margins and long-term site control. No country-level revenue disclosure was provided in the excerpts, so the geographic profile is best understood as U.S.-only operating exposure.

- **United States** (100%) — Tower ownership and operations are U.S.-based; no separate revenue geography table was provided.

- Operations are concentrated in the United States
- Tower portfolio spans 19 states
- Rural, suburban, and urban sites support different tenancy economics
- More than one-third of towers have no competing structure within two miles
- Local ground lease terms affect site economics and renewal risk
- No country-level revenue split was disclosed in the excerpts

## Strategy

Array’s strategy is to increase colocation on its existing tower portfolio, which is the main lever for revenue growth because incremental tenants can be added with limited new capital. The company is also focused on optimizing ground leases by purchasing ground interests and renewing leases ahead of expiration, which should improve long-term site economics. A major near-term priority is executing the T-Mobile MLA, including committed site lease agreements, interim leases, and additional tenancy opportunities beyond the minimum commitment. Array is also evaluating towers without tenants to determine whether they can be leased, restructured, or ultimately divested or decommissioned. More broadly, the company is repositioning itself as a pure-play digital infrastructure owner after exiting wireless services, while also seeking to monetize retained spectrum assets.

- **Grow colocation on existing towers** (short-term) — Additional tenants can be added to existing sites, improving revenue density and returns without requiring large new tower construction.
- **Complete T-Mobile MLA execution** (short-term) — The MLA provides a large, long-duration revenue base and is central to near-term site rental growth.
- **Optimize ground lease economics** (medium-term) — Ground rent is a major operating cost, so better site control can protect margins and reduce renewal risk.
- **Unlock value from towers without tenants** (medium-term) — Underutilized towers may still have leasing potential or alternative monetization value.

- Increase colocation on existing towers to grow cash flow with limited new build cost
- Execute the T-Mobile MLA and convert committed sites into long-term revenue
- Add incremental tenants above contractual minimums through dedicated sales coverage
- Optimize ground leases through purchases and early renewals
- Evaluate towers without tenants for leasing, rationalization, divestiture, or decommissioning
- Monetize retained spectrum opportunistically
- Operate as a focused tower company after exiting wireless services

## Risks

Array is exposed to customer concentration risk because a substantial portion of revenue comes from a small number of wireless tenants, especially T-Mobile, Verizon, AT&T, and DISH Wireless. If carriers reduce network spending, consolidate, share spectrum, or shift investment away from tower-based infrastructure, demand for leasing space could weaken. The company also faces contract and credit risk from DISH Wireless, which has disputed obligations and missed certain payments, creating uncertainty around future collections. Operationally, ground rent escalation can outpace colocation rent escalation, compressing margins over time, while cyberattacks, denial-of-service events, and technology failures could disrupt operations and damage customer trust. More broadly, the tower industry is sensitive to 5G deployment timing, FCC spectrum activity, and the possibility that new technologies or 6G use cases reduce the need for traditional towers.

- **Customer concentration** [high] — A small number of large wireless carriers account for a substantial portion of revenue, so any spending cut or contract loss would quickly affect site rental income.
- **DISH Wireless contract dispute and nonpayment** [high] — DISH has claimed obligations are excused and has failed to make certain payments, creating collection and legal uncertainty.
- **Ground lease escalation** [medium] — Ground rent is the largest operating cost and many leases have fixed escalators that may rise faster than tower rent.
- **Cybersecurity incidents** [medium] — A breach or denial-of-service attack could interrupt operations, expose data, and create remediation and litigation costs.
- **Technology substitution** [medium] — New network architectures, spectrum sharing, or 6G deployment patterns could reduce tower demand over time.

- High tenant concentration, especially dependence on T-Mobile
- DISH Wireless payment dispute and contract enforcement uncertainty
- Carrier consolidation or lower capex reducing tower demand
- Ground rent inflation exceeding colocation rent escalators
- Cybersecurity and denial-of-service attacks on IT and operations
- Technology shifts that reduce the need for tower-based infrastructure
- Regulatory and spectrum deployment delays affecting carrier investment

## Accounting

Array’s reported results are heavily affected by lease accounting and the timing of site rental revenue recognition under long-term customer agreements. The T-Mobile MLA creates meaningful quarter-to-quarter variability because interim leases are temporary and management expects some of that revenue to decline as cancellations occur, while the long-term lease commitments extend revenue visibility. Ground leases and tower colocation contracts often include fixed annual escalators, so the spread between revenue escalators and ground rent escalators is an important accounting and economic assumption for margin analysis. The company also carries retained spectrum and evaluates it for monetization and impairment risk, which can create judgment-heavy valuation outcomes if expected sale proceeds or use changes. In addition, decommissioning costs, asset retirement obligations, and other deferred liabilities require estimates that can materially affect reported liabilities and future expense recognition.

- **Lease revenue recognition under MLAs** — Affects site rental revenue timing and comparability across periods
- **Ground lease and colocation escalators** — Affects operating margin and cash flow analysis
- **Spectrum valuation and impairment** — Affects asset carrying values and non-cash charges
- **Asset retirement obligations and decommissioning costs** — Affects liabilities, expense recognition, and balance sheet estimates

- Long-term lease revenue recognition affects timing of site rental income
- T-Mobile MLA interim leases can create temporary revenue spikes and later declines
- Fixed annual escalators on both tenant leases and ground leases affect margin trends
- Retained spectrum requires valuation and possible impairment judgments
- Asset retirement obligations and decommissioning estimates affect liabilities and expense
- Discontinued operations from the wireless services exit affect comparability across periods
