Crown Castle Inc.

What they do

Crown Castle owns, operates and leases roughly 40,000 towers and other structures such as rooftops across the U.S., providing space or capacity to wireless tenants under long-term lease, license, sublease and service agreements. Site rental revenues were 96% of second quarter 2026 consolidated net revenues, and the vast majority of that revenue is recurring under long-term contracts. Its largest tenants are T-Mobile, AT&T and Verizon Wireless, which together accounted for approximately 90% of 2025 site rental revenues. As an ancillary business it also provides site development services such as site acquisition, engineering and zoning and permitting.

Revenue drivers

• Towers site rental — The sole reportable segment after the Fiber Business was reclassified to discontinued operations; site rental revenues represented 95% of 2025 net revenues and 96% of second quarter 2026 consolidated net revenues.
• Tenant additions on existing towers — Adding or modifying tenant equipment on existing towers is the stated core driver of growth, producing high incremental returns because of low incremental operating costs.
• U.S. tower footprint concentration — Approximately 56% of towers are in the 50 largest U.S. basic trading areas and 71% in the 100 largest, with a presence in each of the top 100 BTAs.
• Site development services — Ancillary pre-construction services for existing or new tenant equipment installations, including site acquisition, architectural and engineering, and zoning and permitting.

Recent performance

The Strategic Fiber Transaction closed on May 1, 2026, with Crown Castle receiving aggregate net cash proceeds of $8.4 billion, or the $8.5 billion gross contractual purchase price less $124 million of preliminary purchase price adjustments. The Fiber Business is reported as discontinued operations for all periods presented, including a $280 million loss from disposal of discontinued operations in the second quarter of 2026 and $625 million for the six months then ended. Recent quarterly revenue declined sequentially from $60 million at 2025-09-30 to $53 million, $49 million and $41 million at 2026-06-30. As of June 30, 2026, total assets were $21.51 billion, total liabilities were $24.78 billion and shareholder equity was negative $3.27 billion. Long-term debt was $24.34 billion at December 31, 2025.

Strategy

Management states its strategy is to create long-term stockholder value by growing cash flows from the existing tower portfolio, returning a meaningful portion of operating cash flow to stockholders through dividends and share repurchases, and investing capital efficiently to grow cash flows and long-term dividends per share. The company frames the U.S. as the most attractive tower market with the greatest long-term growth potential, and says its towers offer an efficient, cost-effective solution for wireless tenants expanding coverage and capacity. Capital investment has historically included constructing and acquiring new towers and acquiring land interests. Pending the fiber sale, Crown Castle continues to operate the divested businesses under the Strategic Fiber Agreement until closing. The company operates as a REIT for U.S. federal income tax purposes.

Risks

• Tenant concentration — T-Mobile, AT&T and Verizon Wireless collectively accounted for approximately 90% of 2025 site rental revenues, so loss, consolidation or financial instability of any one of them could materially decrease revenues.
• Dependence on network investment — The business depends on demand for data and on tenants' network investment, and a reduction in the amount or a change in the mix of that investment may reduce demand for Crown Castle's towers.
• DISH default and termination — The 10-K references a notice of default and termination delivered to DISH Wireless L.L.C., and the $23.7 billion of expected future tenant contract cash inflows as of December 31, 2025 is stated exclusive of amounts owed from DISH.
• Land and rights retention — Failure to retain rights to communications infrastructure, including the land under towers, could adversely affect the business; roughly 60% of towers Adjusted Site Rental Gross Margin comes from towers on leased, subleased, managed or licensed land.

Outlook

The 10-K includes a full year 2026 outlook and plans, and the second quarter 2026 supplemental package presents an outlook for full year 2026 plus outlooks for components of changes in site rental revenues and interest expense. Management's forward-looking items also cover demand for towers, the impact of the Sprint cancellations and DISH terminations, and proceeds from the fiber sale. The supplemental package reflects the company operating as a single towers segment following the May 1, 2026 close.
