“During 2024, we made significant progress on the strategic review of alternatives at UScellular,” said Walter C. D. Carlson, TDS President and CEO. “And as part of our mission to provide outstanding communication services to our customers, both business units invested in their high-quality networks. UScellular continued to deploy its mid-band spectrum to enhance speed and capacity while TDS Telecom grew its footprint and delivered 129,000 new marketable fiber service addresses.
“In 2025, TDS Telecom will continue its ongoing fiber expansion and the FCC’s Enhanced Alternative Connect America Cost Model program and intends to bring a fiber-rich network to over 150,000 new marketable service addresses throughout the country. And while UScellular works toward a successful close on the sale of its wireless operations and spectrum transactions, UScellular remains focused on its operational priorities and growing its tower business.”
Announced Transactions
On May 24, 2024, TDS and UScellular entered into a Securities Purchase Agreement to sell UScellular's wireless operations and select spectrum assets to T-Mobile US, Inc. (T-Mobile). The transaction is expected to close in mid-2025, subject to regulatory approval and the satisfaction of customary closing conditions.
On October 17, 2024, UScellular, and certain subsidiaries of UScellular, entered into a License Purchase Agreement with Verizon Communications, Inc. (Verizon) to sell certain AWS, Cellular and PCS wireless spectrum licenses, subject to receipt of regulatory approvals, and agreed to grant Verizon certain rights to lease such licenses prior to the transaction close. Additionally, UScellular also entered into agreements with Nsight Spectrum, LLC and Nex-Tech Wireless, LLC for the sale of select spectrum licenses.
On November 6, 2024, UScellular, and certain subsidiaries of UScellular, entered into a License Purchase Agreement with New Cingular Wireless PCS, LLC (AT&T), a subsidiary of AT&T, Inc. to sell certain 3.45 GHz and 700 MHz wireless spectrum licenses, subject to receipt of regulatory approvals, and agreed to grant AT&T certain rights to lease and sub-lease such licenses prior to the transaction close.
Due to the pending transaction with T-Mobile, UScellular is not providing 2025 financial guidance.

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 February 21, 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.

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. Additional information and reconciliations related to Non-GAAP financial measures for December 31, 2024, can be found on TDS' website at investors.tdsinc.com.

1First quarter 2024 connections were adjusted to remove subscribers that could no longer access the UScellular network due to the CDMA shutdown. This resulted in 11,000 and 2,000 subscribers removed from the postpaid and prepaid base, respectively, that are not included in Net additions (losses) for the quarter.
2Average 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.
3Average 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.
4Handset upgrade rate calculated as total handset upgrade transactions divided by average postpaid handset connections.
5Churn rate represents the percentage of the connections that disconnect service each month. These rates represent the average monthly churn rate for each respective period.
6Fourth quarter 2023 Prepaid ARPU excludes a $6 million reduction of prepaid revenue related to an adjustment to correct a prior period error recorded in the fourth quarter of 2023.
7Market penetration is calculated by dividing the number of wireless connections at the end of the period by the total estimated population of consolidated operating markets.

EBITDA, Adjusted EBITDA and Adjusted OIBDA

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