Array reports second quarter 2025 results

CHICAGO (August 11, 2025) — Array Digital Infrastructure, Inc. (NYSE:USM) reported total operating revenues of $916 million for the second quarter of 2025, versus $927 million for the same period one year ago. Service revenues totaled $736 million, versus $743 million for the same period one year ago. Net income attributable to Array shareholders and related diluted earnings per share were $31 million and $0.36, respectively, for the second quarter of 2025 compared to $17 million and $0.20, respectively, in the same period one year ago.
Recent Highlights*
•On August 1, 2025, Array completed the sale of its wireless operations and select spectrum assets to T-Mobile for total consideration of $4.3 billion which includes a combination of cash and assumed debt
•Declared a $23.00 per share special dividend payable on August 19, 2025
•Third-party tower revenues increased 12%
•Pending AT&T and Verizon spectrum transactions are expected to close in 2H 2025 and Q3 2026, respectively, subject to receipt of regulatory approvals and satisfaction of closing conditions

* Comparisons are 2Q’24 to 2Q’25 unless otherwise noted

“I am pleased that we have successfully closed the T-Mobile deal and have declared a special dividend in connection with the transaction,” said Doug Chambers, Array interim President and CEO. “As a tower company with 4,400 towers and a new Master License Agreement with T-Mobile, Array has strength and stability from its current tower revenue stream, along with an excellent opportunity to grow colocations and revenues, and to expand margins over time. Our non-controlling investment interests also continue to generate significant cash flow. Further, I look forward to closing our announced spectrum transactions and continuing to work toward opportunistically monetizing our remaining spectrum."

Pending previously announced transactions
On October 17, 2024, the company entered into a License Purchase Agreement with Verizon Communications, Inc. (Verizon) to sell certain AWS, Cellular and PCS wireless spectrum licenses, subject to receipt of regulatory approvals, and agreed to grant Verizon certain rights to lease such licenses prior to the transaction close. Additionally, Array also entered into agreements with Nsight Spectrum, LLC and Nex-Tech Wireless, LLC for the sale of select spectrum licenses.

On November 6, 2024, the company also entered into a License Purchase Agreement with New Cingular Wireless PCS, LLC (AT&T), a subsidiary of AT&T Inc. to sell certain 3.45 GHz and 700 MHz wireless spectrum licenses, subject to receipt of regulatory approvals, and agreed to grant AT&T certain rights to lease and sub-lease such licenses prior to the transaction close.

1Average Revenue Per User (ARPU) - metric is calculated by dividing a revenue base by an average number of connections and by the number of months in the period. These revenue bases and connection populations are shown below:
•Postpaid ARPU consists of total postpaid service revenues and postpaid connections.
•Prepaid ARPU consists of total prepaid service revenues and prepaid connections.
2Average Revenue Per Account (ARPA) - metric is calculated by dividing total postpaid service revenues by the average number of postpaid accounts and by the number of months in the period.
3Handset upgrade rate calculated as total handset upgrade transactions divided by average postpaid handset connections.
4Churn rate represents the percentage of the connections that disconnect service each month. These rates represent the average monthly churn rate for each respective period.
5Market penetration is calculated by dividing the number of retail wireless connections at the end of the period by the total estimated population of consolidated operating markets. The methodology for the calculation was updated in the second quarter of 2025 and prior periods were revised to reflect this change.
6Represents instances where a third-party wireless carrier rents or leases space on a company-owned tower.
7Average number of tenants that lease space on company-owned towers, measured on a per-tower basis.

EBITDA, Adjusted EBITDA and Adjusted OIBDA Reconciliations
(Unaudited)

EBITDA, Adjusted EBITDA and Adjusted OIBDA are defined as net income adjusted for the items set forth in the reconciliations below. EBITDA, Adjusted EBITDA and Adjusted OIBDA are not measures of financial performance under Generally Accepted Accounting Principles in the United States (GAAP) and should not be considered as alternatives to Net income or Cash flows from operating activities, as indicators of cash flows or as measures of liquidity. Array does not intend to imply that any such items set forth in the reconciliations below are infrequent or unusual; such items may occur in the future. Management uses Adjusted EBITDA and Adjusted OIBDA as measurements of profitability, and therefore reconciliations to Net income are deemed appropriate. Management believes Adjusted EBITDA and Adjusted OIBDA are useful measures of Array’s operating results before significant recurring non-cash charges, nonrecurring expenses, gains and losses, and other items as presented below as they provide additional relevant and useful information to investors and other users of Array’s financial data in evaluating the effectiveness of its operations and underlying business trends in a manner that is consistent with management’s evaluation of business performance. Adjusted EBITDA shows adjusted earnings before interest, taxes, depreciation, amortization and accretion, gains and losses, and expenses related to the strategic alternatives review of Array while Adjusted OIBDA reduces this measure further to exclude Equity in earnings of unconsolidated entities and Interest and dividend income in order to more effectively show the performance of operating activities excluding investment activities. The following tables reconcile EBITDA, Adjusted EBITDA and Adjusted OIBDA to the corresponding GAAP measure, Net income, Income before income taxes and/or Operating income. Income and expense items below Operating income are not provided at the individual segment level for Array Wireless and Array Towers; therefore, the reconciliations begin with EBITDA and the most directly comparable GAAP measure is Operating income rather than Net income at the segment level.
