"As I look forward, our priorities remain the same – support the T-Mobile integration, grow colocation revenue, optimize our ground leases, and monetize our remaining spectrum,” Carlson continued.

Pending transactions

Subsequent to the August 1, 2025 close of the sale of wireless operations, Array 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 customary 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 and agreed to grant Verizon certain rights to lease such licenses prior to the transaction close. The transaction is expected to close in the second or third quarter of 2026, subject to regulatory approval and other customary closing conditions, and the termination of the T-Mobile Short-Term Spectrum Manager Lease Agreement.

2026 Estimated Results

Array's current estimates of full-year 2026 results are shown below. Such estimates represent management’s view as of February 20, 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 tables reconcile EBITDA, Adjusted EBITDA, and Adjusted OIBDA to the corresponding GAAP measures, Net income (loss) from continuing operations or Income (loss) 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 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.

EBITDA, Adjusted EBITDA, Adjusted OIBDA and AFCF Reconciliations (Unaudited) EBITDA, Adjusted EBITDA and Adjusted OIBDA The following tables reconcile EBITDA, Adjusted EBITDA and Adjusted OIBDA to the corresponding GAAP measure, Net income (loss) from continuing operations 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 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. Array modified its AFCF metric for the three months ended December 31, 2025 to adjust for cash taxes paid in the quarter, which management believes best reflects cash generated from operations and investments. Under the modified presentation, the comparative calculation of AFCF for the three months ended September 30, 2025 would have been $63.4 million.
