What Array Digital Infrastructure does

Array Digital Infrastructure, Inc. (NYSE: AD) is a U.S. owner and operator of shared wireless communications infrastructure, formed in 2025 as a spin-off of the tower assets of United States Cellular Corporation (UScellular). The company owns and operates a portfolio of more than 4,400 cell towers across 19 states, including a deliberate concentration in rural and underserved markets, and is headquartered in Chicago, Illinois. Array is the fourth largest public tower company in the United States according to Inside Towers and is a majority-owned subsidiary of Telephone and Data Systems, Inc. (NYSE: TDS).

The company's core offering is shared tower infrastructure — physical sites that wireless carriers, government agencies, municipalities, wireless internet service providers, broadband providers, and utility providers lease for equipment colocation, including 5G and other wireless technologies. Supporting products include a self-service Tower Locator web tool that lets prospective tenants identify candidate sites, an online application portal for lease inquiries, and pre-negotiated Master Lease Agreements that streamline tenant onboarding with major wireless carriers. Revenue is generated primarily through recurring, multi-year tower lease rentals under a subscription-style model; pricing is quote-based and not publicly disclosed.

Array sells through an enterprise field sales motion led by a dedicated Senior Director of Tower Sales & Business, supplemented by direct email inquiry and industry event participation (e.g., Connect (X)). The company is in the early stages of operating as a standalone public entity — Anthony Carlson was appointed President and CEO in November 2025 — with strategic priorities centered on tenancy growth, new colocation applications, closing pending spectrum transactions with T-Mobile, and expanding public-sector and broadband tenant relationships.

Emerging players

• Phoenix Tower International: Phoenix Tower owns and operates ~25,000 towers across the Americas and Caribbean. It is comparable to Array as a growth-oriented, multi-region tower operator competing for carrier build-to-suit mandates.
• Uniti Group: Uniti Group is a US-focused communications infrastructure REIT operating towers and fiber assets. While more fiber-weighted than Array, it shares the carrier-tower tenant model and is a relevant adjacent comparable for infrastructure investors.
• Helios Towers plc: Helios Towers operates ~14,000 sites across Africa and the Middle East. It is comparable to Array as a growth-stage, multi-country tower operator reliant on carrier colocation economics.

Broad incumbents

• DigitalBridge Group: DigitalBridge is a leading digital infrastructure investment firm with tower, data center and fiber assets. It is a broader incumbent in the same communications infrastructure asset class as Array and a potential capital partner.
• Cellnex Telecom: Cellnex is Europe's largest tower operator with 100,000+ sites across Europe. It shares the same shared-infrastructure colocation business model as Array but operates in a different geography, making it a broad incumbent comparable.

Direct peers

• Vertical Bridge Holdings: Vertical Bridge is the largest private US tower company with 20,000+ owned and master-leased sites. It competes head-to-head with Array for carrier colocation, government/public-safety, and broadband tenants.
• American Tower Corporation: American Tower is the largest publicly traded tower company globally with 220,000+ communications sites. It is the most direct comparable to Array in business model (shared wireless infrastructure colocation) and customer base (the same major US wireless carriers).
• Crown Castle Inc. Crown Castle owns approximately 40,000 US cell towers and a fiber business serving the same wireless carrier customers as Array. Mike Smith, Array's Senior Director of Tower Sales, spent 20+ years at Crown Castle, underscoring operational comparability.
• SBA Communications Corporation: SBA Communications operates ~30,000 tower sites across the Americas and Africa, sharing Array's pure-play tower REIT-like model and carrier tenant base. Coleman Prewitt, Array's Senior Director of Legal, spent 15 years at SBA in M&A and Associate General Counsel roles.

Regional players

• Telesites S.A.B. de C.V. Telesites is one of the largest tower operators in Mexico, with assets spun out of América Móvil. It mirrors Array's recent spin-off origin and shared-infrastructure business model but is geographically concentrated in Mexico.
