Array has investments in three companies in the state of Iowa. On August 1, 2025, in three separate transactions, these entities sold their wireless operations to T-Mobile. Array recognized $33 million of equity income and received $42 million of distributions in the third quarter of 2025 related to these three transactions.

Certain Array investments in Verizon wireless operating companies were subject to Verizon's prepaid lease transaction with Vertical Bridge. Array received distributions from these investments in the aggregate amount of $25 million in the first half of 2025 related to this transaction.

Prior period adjustments made by the managers of certain investee entities had the impact of reducing distributions from investee operations in 2025.

In the first quarter 2026, equity income was elevated due to prior-period adjustments recorded by the managers of certain investee entities. Regarding distributions, certain entities distribute cash only twice per year, resulting in an uneven distribution pattern throughout the year.

Cash Expenses

Total cash expenses represent total operating expenses as shown in the Consolidated Statement of Operations Highlights in the TDS and Array SEC Forms 8-K, less depreciation, amortization and accretion and gain/losses.

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 on slides 25 through 27. 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. TDS and Array do not intend to imply that any such items set forth in the reconciliations on slides 25 through 27 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 TDS' and Array's operating results before significant recurring non-cash charges, nonrecurring expenses, gains and losses, and other items as presented above as it provides additional relevant and useful information to investors and other users of TDS' and 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. The tables on slides 25 through 27 reconcile EBITDA, Adjusted EBITDA and Adjusted OIBDA to the corresponding GAAP measure, Net income or Income before income taxes. Additional information and reconciliations related to Non-GAAP financial measures for December 31, 2025, can be found on TDS' and Array's websites at investors.tdsinc.com and investors.arrayinc.com.

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 on slide 28. 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 table on slide 28 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.
