Array updates 2026 guidance

CHICAGO (August 7, 2026) — Array Digital Infrastructure, Inc. (NYSE:AD) reported second quarter operating results.

“Array continues to make nice progress executing across our 2026 priorities,” said Anthony Carlson, President and CEO. “The organization remains laser-focused on optimizing our tower operations - as evidenced by our sequential tower tenancy growth. And we continue to monetize our remaining spectrum assets as well as support T-Mobile’s integration.”

Highlights*

•Optimizing tower operations

◦Site rental revenues grew 95% year over year

◦Delivered consecutive quarter over quarter tower tenancy growth •Continuing to close pending sales of wireless spectrum ◦Closed on sale of certain 700 MHz wireless spectrum licenses for total proceeds of $74.8 million on May 5, 2026 ◦Closed on sale of certain 600 MHz wireless spectrum licenses for total proceeds of $86.4 million on May 12, 2026 ◦Closed on sale of certain cellular and other spectrum licenses for total proceeds of $1 billion on June 1, 2026 ◦Issued special dividend of $11 per common share on June 25, 2026 •Updated 2026 Guidance ◦Narrowed Revenue range to $205 million - $215 million on higher interim site revenue ◦Increased Adjusted EBITDA range to $220 million - $235 million ◦Capital expenditures range remains unchanged at $25 million - $35 million * Comparisons are 2Q’25 to 2Q’26 unless otherwise noted.

Array reported total operating revenues from continuing operations of $54.1 million for the second quarter of 2026, versus $28.5 million for the same period one year ago. Net income attributable to Array shareholders and diluted earnings per share from continuing operations were $333.8 million and $3.86, respectively, for the second quarter of 2026 compared to $14.8 million and $0.17, respectively, in the same period one year ago.

Pending transactions

Subsequent to the August 1, 2025 close of the sale of wireless operations, Array reached additional agreements with T-Mobile for the sale of additional spectrum. A significant portion of these closed in May 2026 with approximately $30 million related to 600 MHz and 700 MHz licenses remaining. These additional transactions are expected to close yet in 2026, subject to regulatory approval and customary closing conditions.

DISH Wireless

In September 2025, Array received a letter from DISH Wireless claiming that its obligations under its Master Lease Agreement with Array were excused due to actions taken by the FCC and subsequent agreements to sell spectrum assets. Beginning in the first quarter of 2026, Array no longer recognizes revenue in connection with DISH. In June 2026, DISH Wireless and other DISH entities filed for bankruptcy and Array is monitoring those proceedings.

Recent Development

On May 7, 2026, TDS delivered to the Array Board of Directors a letter setting forth a non-binding proposal to acquire all of the outstanding Array Common Shares that are not owned by TDS (the “Array Proposal”). A special committee of independent and disinterested directors of the Array Board of Directors has been formed to evaluate this proposal. For additional information on the Array Proposal, see TDS’ Current Report on Form 8-K, filed with the U.S. Securities and Exchange Commission on May 8, 2026.

2026 Estimated Results

Array’s current estimates of full-year 2026 results are shown below. Such estimates represent management’s view as of August 7, 2026 and should not be assumed to be current as of any future date. Array undertakes no duty to update such estimates, whether as a result of new information, future events, or otherwise. There can be no assurance that final results will not differ materially from estimated results.

The following table reconciles EBITDA, Adjusted EBITDA and Adjusted OIBDA to the corresponding GAAP measures, Net income from continuing operations or Income before income taxes. In providing 2026 estimated results, Array has not completed the below reconciliation to Net income because it does not provide guidance for income taxes. Although potentially significant, Array believes that the impact of income taxes cannot be reasonably predicted; therefore, Array is unable to provide such guidance.

Numbers may not foot due to rounding.

1EBITDA, Adjusted EBITDA and Adjusted OIBDA are defined as net income from continuing operations adjusted for the items set forth in the reconciliation above. 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 reconciliation above 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 above 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 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.

1Represents instances where a third-party leases space on a company-owned tower. Includes T-Mobile MLA committed site minimum of 2,015. Excludes Interim Sites whereby T-Mobile is leasing up to 1,800 sites for a period of up to 30 months subject to the terms and conditions of the MLA. As of March 31, 2026, the Number of colocations and the Tower tenancy rate exclude DISH Wireless due to the low probability of fulfilling its lease commitments.

2Calculated as total number of colocations divided by total number of towers. Includes T-Mobile MLA committed site minimum of 2,015. Excludes Interim Sites whereby T-Mobile is leasing up to 1,800 sites for a period of up to 30 months subject to the terms and conditions of the MLA. As of March 31, 2026, the Number of colocations and the Tower tenancy rate exclude DISH Wireless due to the low probability of fulfilling its lease commitments. Normalized to exclude DISH, tenancy ratios would have been 0.95 and 0.94 for December 31, 2025 and September 30, 2025, respectively.

EBITDA, Adjusted EBITDA, Adjusted OIBDA and AFCF Reconciliations (Unaudited) EBITDA, Adjusted EBITDA and Adjusted OIBDA The following table reconciles EBITDA, Adjusted EBITDA and Adjusted OIBDA to the corresponding GAAP measure, Net income from continuing operations and Income 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 its noncontrolling investment interests. The following table reconciles AFCF to the corresponding GAAP measure, Net income from continuing operations. This measure is presented following the sale of Array's wireless operations to T-Mobile on August 1, 2025, at which time the primary business operations for Array changed from providing wireless communications services to a standalone tower company.
