Array reports third quarter 2025 results CHICAGO (November 7, 2025) — Array Digital Infrastructure, Inc. (NYSE:AD) reported total operating revenues from continuing operations of $47.1 million for the third quarter of 2025, versus $25.7 million for the same period one year ago. Net income (loss) attributable to Array shareholders and related diluted earnings (loss) per share from continuing operations were $108.8 million and $1.25, respectively, for the third quarter of 2025 compared to $(95.9) million and $(1.12), respectively, in the same period one year ago. Recent Highlights* • Closed on the sale of wireless operations and select spectrum assets to T-Mobile on August 1, 2025 • Paid a $23 per share special dividend on August 19, 2025 • Commenced T-Mobile MLA on August 1, 2025, helping to drive a 68% increase in Site rental revenues, excluding non- cash amortization • Entered into additional spectrum sales expected to result in aggregate proceeds of $178 million • Announced appointment of Anthony Carlson as President and CEO effective November 16, 2025 * Comparisons are 3Q’24 to 3Q’25 unless otherwise noted “We are off to a great start as an independent tower company,” said Doug Chambers, Array Interim President and CEO. “The new T-Mobile MLA commenced on August 1, and the team has been doing an outstanding job on the implementation effort. This new MLA drove a 68 percent year-over-year increase in Site rental revenue, excluding non-cash amortization. We have also made great progress monetizing our spectrum as we entered into additional agreements to sell our remaining spectrum and have now closed or signed agreements to monetize 70 percent of our spectrum portfolio.” Pending transactions Subsequent to the August 1, 2025 close of the sale of wireless operations, Array has reached additional agreements with T-Mobile for 700 MHz spectrum licenses, AWS and a portion of the 600 MHz put/call totaling $178 million in aggregate expected proceeds, subject to closing conditions and regulatory approvals. On October 17, 2024, Array, and certain subsidiaries of Array, 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. On November 6, 2024, Array, and certain subsidiaries of Array, 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. Leadership Transition at Array As separately announced, Anthony Carlson will become President and CEO of Array on November 16, succeeding Interim President and CEO Doug Chambers. “Now that we have Array established as a standalone tower company, we are ready to announce its next step in leadership, selecting Anthony Carlson to be Array’s President and CEO,” said Walter Carlson, Chairman of the Array Board of Directors. “Anthony’s substantial and increasing responsibilities at UScellular and TDS Telecom over the past six years provide him with the right foundation to lead Array’s growing tower business and provide strategic vision to its operations.” See separately issued announcement on November 7, 2025 for more information on our leadership transition. 1

Array Digital Infrastructure, Inc. EBITDA, Adjusted EBITDA, Adjusted OIBDA and AFCF Reconciliations (Unaudited) EBITDA, Adjusted EBITDA and Adjusted OIBDA 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 (loss) and Income (loss) before income taxes.

Adjusted Free Cash Flow (AFCF) AFCF is a non-GAAP measure defined as Net income from continuing operations adjusted for the items set forth in the reconciliation below. AFCF is not a measure of financial performance under GAAP and should not be considered as an alternative to Net income from continuing operations or as an indicator of cash flows. Management believes AFCF is a useful measure of Array’s cash generated from operations and investments. The following table reconciles AFCF to the corresponding GAAP measure, Net income from continuing operations. This measure will only be presented prospectively as following the sale of Array's wireless operations to T-Mobile on August 1, 2025, the primary business operations for Array changed from providing wireless communications services to a standalone tower company. In addition, Array continues to own noncontrolling interests in investments that earn significant income, and generate significant cash flows. Three Months EndedSeptember 30, 2025 (Dollars in thousands) Net income from continuing operations (GAAP) $ 109,920 Add back or deduct: Deferred income taxes (80,572) Short-term imputed spectrum lease income (30,413) Amortization of deferred debt charges 274 Equity in earnings of unconsolidated entities (69,811) Distributions from unconsolidated entities 61,794 (Gain) loss on license sales and exchanges, net (1,323) (Gain) loss on asset disposals, net 707 Loss on impairment of licenses 47,679 Depreciation, amortization and accretion 11,868 Expenses related to strategic alternatives review 489 Straight line and other non-cash revenue adjustments (3,872) Straight line expense adjustment 1,559 Maintenance and other capital expenditures (2,374) Adjusted Free Cash Flow from continuing operations (Non-GAAP) $ 45,925 10
