CHICAGO (November 6, 2026) — Array Digital Infrastructure, Inc. (NYSE:AD) reported third quarter operating results.

“As Array marks its first year as a tower company, we continue to make meaningful progress against our 2026 strategic priorities,” said Anthony Carlson, President and CEO. “Our team remains intensely focused on maximizing the value of our tower portfolio by driving tenant growth and enhancing operational efficiency. These efforts are strengthening the earnings power of our assets and positioning the company for long-term value creation."

Highlights*

•Optimizing tower operations

◦Site rental revenues grew 14% year over year

◦Delivered consecutive quarter-over-quarter colocation growth •Continuing to close pending sales of wireless spectrum ◦Received regulatory approval for remaining pending transactions in October, closings remain subject to FCC finality and other customary closing conditions •Reaffirming 2026 financial guidance * Comparisons are 3Q’25 to 3Q’26 unless otherwise noted.

Array reported total operating revenues from continuing operations of $53.9 million for the third quarter of 2026, versus $47.1 million for the same period one year ago. Net income attributable to Array shareholders and diluted earnings per share from continuing operations were $69.6 million and $0.81, respectively, for the third quarter of 2026 compared to $108.8 million and $1.25, respectively, in the same period one year ago.

Pending transactions

Subsequent to the August 1, 2025 close of the sale of its wireless operations, Array reached additional agreements with T-Mobile for the sale of spectrum. A significant portion of these closed in May 2026 with approximately $30 million related to 600 MHz and 700 MHz licenses remaining. These remaining transactions received regulatory approval on October 7, 2026 and are expected to close in 2026, subject to FCC finality and other customary closing conditions.

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”). On September 1, 2026, TDS announced that it is no longer pursuing the Array Proposal. For additional information, see TDS' Current Report on Form 8-K filed with the U.S. Securities and Exchange Commission on September 2, 2026.

2026 Estimated Results

Array’s current estimates of full-year 2026 results are shown below. Such estimates represent management’s view as of November 6, 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, expenses related to strategic alternatives review, 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, expenses related to the strategic alternatives review and short-term imputed spectrum lease income, 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.

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.

1Substantially all of the cash paid for income taxes are related to the sale of various wireless spectrum licenses in 2026.
