UNITED STATES CELLULAR CORP

The following discussion and analysis compares United States Cellular Corporation’s (UScellular) financial results for the three and nine months ended September 30, 2024, to the three and nine months ended September 30, 2023. It should be read in conjunction with UScellular’s interim consolidated financial statements and notes included herein, and with the description of UScellular’s business, its audited consolidated financial statements and Management's Discussion and Analysis of Financial Condition and Results of Operations (MD&A) included in UScellular’s Annual Report on Form 10-K (Form 10-K) for the year ended December 31, 2023. Certain numbers included herein are rounded to millions for ease of presentation; however, certain calculated amounts and percentages are determined using the unrounded numbers.

During the second quarter of 2024, UScellular modified its reporting structure due to the planned disposal of its wireless operations and, as a result, disaggregated its operations into two reportable segments – Wireless and Towers. This presentation reflects how UScellular's chief operating decision maker allocates resources and evaluates operating performance following this strategic shift. Prior periods have been updated to conform to the new reportable segments. See Note 13 — Business Segment Information in the Notes to Consolidated Financial Statements for additional information.

The accounting policies of UScellular conform to accounting principles generally accepted in the United States of America (GAAP).

UScellular Mission and Strategy

UScellular’s mission is to connect its customers to what matters most to them. This includes providing exceptional wireless communication services which enhance consumers’ lives, increase the competitiveness of local businesses, and improve the efficiency of government operations in the markets UScellular serves.

UScellular's strategy is to attract and retain customers by providing a high-quality network, outstanding customer service, and competitive devices, plans and pricing - all provided with a local community focus. Strategic efforts include:

▪UScellular offers economical and competitively priced service plans and devices to its customers and is focused on increasing revenues from sales of related products such as device protection plans and from services such as fixed wireless home internet. In addition, UScellular is focused on expanding its solutions available to business and government customers.

▪UScellular continues to enhance its network capabilities, including by deploying 5G technology to help address customers’ growing demand for data services and create opportunities for new services requiring high speed and reliability as well as low latency. In 2019-2023, UScellular focused on 5G coverage and predominantly used low-band spectrum to launch 5G services in portions of substantially all of its markets. During 2023 and 2024, UScellular has focused on deploying 5G over its mid-band spectrum, largely overlapping areas already covered with low-band 5G service to enhance speed and capacity for UScellular’s mobility and fixed wireless services. Investments in the next several years are expected to be focused on continued mid-band spectrum deployment to enhance speed and capacity needs, building on the existing 5G coverage across UScellular’s footprint.

▪UScellular seeks to grow revenue in its Towers segment primarily through increasing third-party colocations on existing towers through providing unique tower locations, attractive terms and streamlined implementation to third-party wireless operators.

Announced Transactions and Strategic Alternatives Review

On August 4, 2023, TDS and UScellular announced that the Boards of Directors of both companies decided to initiate a process to explore a range of strategic alternatives for UScellular. On May 28, 2024, UScellular announced that its Board of Directors unanimously approved the execution of a Securities Purchase Agreement (Securities Purchase Agreement) by and among TDS, UScellular, T-Mobile US, Inc. (T-Mobile) and USCC Wireless Holdings, LLC, pursuant to which, among other things, UScellular agreed to sell its wireless operations and select spectrum assets to T-Mobile for a purchase price, subject to adjustment as specified in the Securities Purchase Agreement, of $4,400 million, which is payable in a combination of cash and the assumption of up to approximately $2,000 million in debt. The Securities Purchase Agreement also contemplates, among other things, a Short-Term Spectrum Manager Lease Agreement that will become effective at the closing date, which provides T-Mobile with an exclusive license to use certain UScellular spectrum assets at no cost for up to one-year for the purpose of providing continued, uninterrupted service to customers. The transactions are expected to close in mid-2025, subject to the receipt of regulatory approvals and the satisfaction of customary closing conditions.

On October 17, 2024, UScellular, and certain subsidiaries of UScellular, entered into a License Purchase Agreement (Verizon 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 for total proceeds of $1,000 million. As of September 30, 2024, the book value of the wireless spectrum licenses to be sold was $586 million. The transaction is subject to regulatory approval and other customary closing conditions, and is contingent on the closing of the T-Mobile transaction and the termination of the T-Mobile Short-Term Spectrum Manager Lease Agreement.

The strategic alternatives review process is ongoing as UScellular seeks to opportunistically monetize its spectrum assets that are not subject to the Securities Purchase Agreement or the Verizon Purchase Agreement.

UScellular incurred third-party expenses related to the announced transactions and strategic alternatives review of $7 million and $28 million for the three and nine months ended September 30, 2024, respectively, and $3 million for both the three and nine months ended September 30, 2023.

Significant Financial Matter

Net loss attributable to UScellular shareholders was $79 million and $44 million for the three and nine months ended September 30, 2024, respectively. Such net losses include a non-cash charge related to the impairment of certain wireless spectrum licenses in the amount of $136 million ($102 million, net of tax impacts), which was recorded during the three months ended September 30, 2024. The conclusion that this impairment was required was made in connection with the review and preparation of the September 30, 2024 financial statements. See Note 8 — Intangible Assets for a detailed discussion regarding this impairment. Refer to Supplemental Information to Non-GAAP Financial Measures within this MD&A for a reconciliation of the wireless spectrum license impairment, net of tax.
