Additionally, we are delighted that Ken Dixon, CEO of TDS Telecom, has joined the organization at a pivotal time for our fiber business.

2025 Estimated Results
TDS’ current estimates of full-year 2025 results for TDS Telecom are shown below. Such estimates represent management’s view as of August 11, 2025 and should not be assumed to be current as of any future date. TDS 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.

Array is not providing 2025 financial guidance.

The following tables reconcile EBITDA, Adjusted EBITDA and Adjusted OIBDA to the corresponding GAAP measures, Net income or Income before income taxes. In providing 2025 estimated results, TDS has not completed the below reconciliation to Net income because it does not provide guidance for income taxes. Although potentially significant, TDS believes that the impact of income taxes cannot be reasonably predicted; therefore, TDS is unable to provide such guidance.

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. TDS 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 TDS’ 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 TDS’ 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. The table above reconciles EBITDA, Adjusted EBITDA and Adjusted OIBDA to the corresponding GAAP measure, Net income or Income before income taxes.

1Average Revenue Per User (ARPU) - metric is calculated by dividing a revenue base by an average number of connections and by the number of months in the period. These revenue bases and connection populations are shown below:
•Postpaid ARPU consists of total postpaid service revenues and postpaid connections.
•Prepaid ARPU consists of total prepaid service revenues and prepaid connections.
2Average Revenue Per Account (ARPA) - metric is calculated by dividing total postpaid service revenues by the average number of postpaid accounts and by the number of months in the period.
3Handset upgrade rate calculated as total handset upgrade transactions divided by average postpaid handset connections.
4Churn rate represents the percentage of the connections that disconnect service each month. These rates represent the average monthly churn rate for each respective period.
5Market penetration is calculated by dividing the number of retail wireless connections at the end of the period by the total estimated population of consolidated operating markets. The methodology for the calculation was updated in the second quarter of 2025 and prior periods were revised to reflect this change.
6Represents instances where a third-party wireless carrier rents or leases space on a company-owned tower.
7Average number of tenants that lease space on company-owned towers, measured on a per-tower basis.

EBITDA, Adjusted EBITDA and Adjusted OIBDA
(Unaudited)

The following table reconciles EBITDA, Adjusted EBITDA and Adjusted OIBDA to the corresponding GAAP measures, Net income and Income before income taxes. Income and expense items below Operating income are not provided at the individual segment level for Array Wireless and Array Towers; therefore, the reconciliations begin with EBITDA and the most directly comparable GAAP measure is Operating income rather than Net income at the segment level.
