TELEPHONE DATA SYSTEMS INC DE

Telephone and Data Systems, Inc. (TDS) provides high-quality communications services to customers with 4.4 million retail wireless connections and 1.1 million broadband, video and voice connections at December 31, 2024. TDS conducts wireless operations through its majority-owned subsidiary, United States Cellular Corporation (UScellular). As of December 31, 2024, TDS owned 83% of the combined total of the outstanding Common Shares and Series A Common Shares of UScellular and controlled 96% of the combined voting power of both classes of UScellular common stock. TDS provides broadband, video, voice and wireless services through its wholly-owned subsidiary TDS Telecommunications LLC (TDS Telecom). TDS Common Shares trade under the ticker symbol “TDS” on the New York Stock Exchange (NYSE). UScellular Common Shares trade on the NYSE under the ticker symbol “USM.”

Under listing standards of the NYSE, TDS is a “controlled company” as such term is defined by the NYSE. TDS is a controlled company because over 50% of the voting power for the election of a majority of the directors of TDS is held by the trustees of the TDS Voting Trust.

During the second quarter of 2024, TDS and UScellular modified their reporting structure due to the planned disposal of the UScellular wireless operations and, as a result, disaggregated the UScellular operations into two reportable segments – Wireless and Towers. TDS has three reportable segments: UScellular Wireless, UScellular Towers and TDS Telecom. TDS operations also include the operations of its wholly-owned subsidiary Suttle-Straus, Inc. (Suttle-Straus). TDS' wholly-owned hosted and managed services (HMS) subsidiary, which operated under the OneNeck IT Solutions brand was sold to a third-party on September 3, 2024. See Note 7 — Divestitures in the Notes to Consolidated Financial Statements for additional information. HMS' and Suttle-Straus’ financial results were not significant to TDS’ operations. All of TDS' segments operate entirely in the United States. See Note 20 — Business Segment Information in the Notes to Consolidated Financial Statements for additional information about TDS' segments.

UScellular OPERATIONS

General

UScellular provides wireless telecommunications services to customers with 4.4 million retail connections in portions of 21 states collectively representing a total population of 33 million. UScellular operates in two reportable segments – Wireless and Towers. All of its wireless operating markets are in the United States.

Operating Strategy, Recent Developments and Community Focus

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 community focus.

UScellular operates a regional wireless network. UScellular’s interests in wireless spectrum licenses include both direct interests whereby UScellular is the licensee and investment interests in entities which are licensees; together, these direct and investment interests involve operating and non-operating wireless spectrum licenses covering portions of 30 states and a total population of approximately 51 million as of December 31, 2024.

UScellular owns and operates towers which support UScellular's wireless network. UScellular also leases space on its owned towers to other wireless service providers. As of December 31, 2024, UScellular owned 4,409 towers with 2,444 third-party colocations.

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 adjustments, 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 purchase price includes $100 million contingent on the satisfaction of certain financial and operational metrics. The purchase price also includes $400 million allocated to certain wireless spectrum licenses held by entities in which UScellular is a non-controlling limited partner. The closing with respect to these wireless spectrum licenses is contingent upon UScellular's purchase, which is pending receipt of regulatory approval, of the remaining equity in the entities that UScellular does not currently own. The Securities Purchase Agreement also contemplates, among other things, a Short-Term Spectrum Manager Lease Agreement and Short-Term Spectrum Manager Sublease Agreements that will become effective at the closing date, which provide T-Mobile with an exclusive license to use certain UScellular spectrum assets and leases at no cost for up to one-year for the sole purpose of providing continued, uninterrupted service to customers. The sale of the wireless business to T-Mobile is 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 December 31, 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.

On November 6, 2024, UScellular, and certain subsidiaries of UScellular, entered into a License Purchase Agreement (AT&T 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 and agreed to grant AT&T certain rights to lease and sub-lease such licenses prior to the transaction close for total proceeds of $1,018 million, subject to certain purchase price adjustments. As of December 31, 2024, the book value of the wireless spectrum licenses to be sold was$859 million. The transaction is subject to regulatory approval and other customary closing conditions and substantially all of the licenses subject to the transaction are contingent on the closing of the T-Mobile transaction. The purchase price includes $232 million allocated to certain wireless spectrum licenses that are held by an entity in which UScellular is a non-controlling limited partner. The closing with respect to these wireless spectrum licenses is contingent upon UScellular's purchase, which is pending receipt of regulatory approval, of the remaining equity in the entity that UScellular does not currently own.

The strategic alternatives review process is ongoing as UScellular works toward closing the transactions signed during 2024, including the T-Mobile, Verizon and AT&T transactions and continues to seek to opportunistically monetize its spectrum assets that are not subject to the Securities Purchase Agreement, the Verizon Purchase Agreement, or the AT&T Purchase Agreement.

As part of its business development strategy, UScellular may periodically be engaged in negotiations relating to strategic partnerships and/or the acquisition, exchange or disposition of companies, strategic properties, spectrum licenses and/or investment interests.

UScellular has a longstanding commitment to supporting its local communities through donations and volunteerism. UScellular focuses its Corporate Social Responsibility program on addressing gaps in STEM (Science, Technology, Engineering and Math) education and connecting tomorrow’s innovators with the resources they need today to help shape their future opportunities. UScellular serves its local communities through exclusive partnerships with acclaimed national nonprofit partners. In 2024, UScellular continued exploring ways to leverage its assets, brand, partnerships, and resources to close the digital divide with a focus on helping to ensure youth in its markets have reliable and fast internet access in school and at home through the After School Access Project. In addition, UScellular continues to participate in the TDS Environmental, Social and Governance (ESG) program. UScellular believes in serving as a good steward of the environment and enacting governance practices that align with its corporate values and commitment to its customers, associates, communities and shareholders.

UScellular contracts with third-party providers for its product warehousing, distribution and direct customer fulfillment activities. UScellular also contracts with third-party providers for its device service programs.

Seasonality. Seasonality in operating expenses may cause operating income to vary from quarter to quarter. UScellular’s operating expenses tend to be higher in the fourth quarter due to increased marketing and promotional activities during the holiday season.

Sales and Distribution Channels

UScellular supports a multi-faceted distribution program, including retail sales, direct sales, telesales, ecommerce, and indirect sales including resellers, independent agents and a third-party national retailer.

Company retail store locations are designed to market wireless services and products to the consumer and small business segments in a setting familiar to these types of customers. Direct sales representatives and the indirect channel sell traditional wireless services as well as IoT and other specialized products and solutions to medium and large-sized businesses and governmental entities. Additionally, the telesales and ecommerce channels enable customers to purchase services and devices via phone and online, respectively.

UScellular has relationships with exclusive and non-exclusive agents (collectively “agents”), which are independent businesses that obtain and service customers for UScellular on a commission basis. UScellular’s agents are generally in the business of selling wireless devices, wireless service plans and other related products to consumer and business and government customers. UScellular provides support and training to its agents to increase customer satisfaction and to ensure a consistent customer experience.

UScellular also maintains a relationship with a large national retailer, selling postpaid and prepaid devices and similar to the agents, this national retailer obtains and services UScellular postpaid and prepaid customers on a commission basis.

Competition

The wireless telecommunication industry is highly competitive. UScellular competes directly with several wireless service providers in each of its markets. In general, there are at least four competitors across UScellular's service area, including to a varying degree: the national wireless companies - Verizon Communications Inc., AT&T Inc., T-Mobile US, Inc., and Dish Network Corporation, cable wireless, which predominantly includes Comcast Corporation and Charter Communications, Inc., and mobile virtual network operators (MVNOs). In addition, UScellular competes with other companies that use alternative communication technology and services to provide similar services and products.

Since each of these competitors has access to comparable technology and facilities, competition among wireless service providers for customers is principally on the basis of types of services and products offered, price, brand, network quality, network speed and responsiveness of customer service. Types of services and products include non–wireless related services such as content offerings that are bundled with wireless services.

Network

Network Technology. Wireless telecommunication systems transmit voice and data signals over networks of radio towers using radio spectrum licensed by the FCC. Access to local, regional, national and worldwide telecommunications networks is provided through system interconnections. A high-quality network, supported by continued investments in that network, is an important factor for UScellular to remain competitive.

5G technology helps address customers’ growing demand for data services and enhanced services, including high-speed fixed wireless home internet services, requiring high speed and reliability as well as low latency. UScellular supports mobility and fixed wireless services through a combination of low-band, mid-band and high-band spectrum. 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. As of December 31, 2024, mid-band spectrum is deployed on sites that covered nearly 50% of data and voice traffic.

UScellular also operates a 4G LTE network including VoLTE technology, which allows customers to utilize a 4G LTE enabled mobile device for voice and data services, including high-definition voice and simultaneous voice and data sessions.

UScellular decommissioned its third-generation (3G) CDMA network in the first quarter of 2024.

Roaming. Inter-carrier roaming agreements are negotiated between wireless operators to enable customers to use wireless services outside of their home service area. UScellular has entered into roaming agreements with a number of wireless companies so that it can offer its customers nationwide services, including 4G LTE, VoLTE and 5G, as well as a variety of international roaming options.

Towers. UScellular owns and leases cell towers to provide service to its customers throughout its footprint. UScellular receives tower rental revenues when another carrier leases tower space on a UScellular owned tower. As of December 31, 2024, there were 7,010 cell sites in service of which UScellular owned 4,409.

TDS TELECOM OPERATIONS

General

TDS Telecom provides communications services to 1.1 million connections in 31 states through its high-quality fiber, coaxial and copper networks. TDS Telecom operates in one reportable segment, and its operating markets are located in a mix of small to mid-sized urban, suburban and rural communities throughout the United States.

Operating Strategy and Community Focus

TDS Telecom invests in high-quality networks, services and products, with the constant focus on delivering outstanding customer service. Through its investments, TDS Telecom intends to improve its broadband services and extend its footprint. TDS Telecom intends to augment that broadband growth by bundling with video, voice, wireless and other value-added services. TDS Telecom seeks to be the preferred broadband provider by offering fiber-rich networks, high-quality products and services, and a seamless customer experience.

A key strategic initiative for TDS Telecom is investing in fiber to provide broadband speeds of up to 8 Gigabits per second (Gbps). Fiber builds allow TDS Telecom to deliver more robust residential and commercial products in its markets that have historically utilized copper technologies and to target attractive, growing markets to increase its total footprint. In 2024, TDS Telecom continued to expand its footprint through fiber investments in Wisconsin and the Pacific Northwest. TDS Telecom may seek to grow its operations through additional investments in fiber and through the acquisition of and/or partnership with businesses that support and complement its existing markets or by creating entirely new clusters of markets in attractive locations. To optimize its portfolio, TDS is exploring opportunities to divest certain markets.

TDS Telecom believes that being a good corporate citizen is fundamental to its long-term success. TDS Telecom is committed to growing with its communities and meeting the needs of customers through great products and services, sponsorships, fundraising, and volunteering. TDS Telecom serves its local communities by financially supporting local projects to serve those in need and by providing TDS Telecom associates with paid time off each year to volunteer. TDS Telecom believes serving its local communities through donations and volunteerism aligns with its corporate values and commitments to its customers, associates, and communities.

Technology

TDS Telecom continues to upgrade and enhance its networks by utilizing various technologies to improve levels of performance and provide additional speed and security to increase value for its customers. The TDS network consists of a highly reliable IP-based broadband network to facilitate the integration of broadband, video and voice services.

In order to provide IP-based services, TDS Telecom has developed and deployed an inter-regional data routing infrastructure using owned and leased fiber capacity which allows it to leverage its 400-gigabit core network. This configuration, along with the continued development of an IP network that interconnects substantially all the existing service territories, provides redundancy and allows for next generation IP service offerings.

TDS Telecom utilizes centralized monitoring and management of its core network to reduce costs and improve service reliability. TDS Telecom continues to standardize equipment and processes to increase efficiency in maintaining its network. Network standardization has aided TDS Telecom in operating its 24-hours-a-day/7-days-per-week Network Management Centers, which continuously monitor the network to proactively identify, minimize, and correct network faults prior to any customer impact.

Customers, Services and Products

Residential. TDS Telecom residential customer operations provide high-speed broadband, video, voice and wireless services. These services are bundled at competitive prices to encourage cross-selling within the customer base and to attract and retain customers.

•Broadband: TDS Telecom offers reliable high-speed internet connections and whole-home Wi-Fi through fiber-rich networks. In certain non-fiber markets, TDS Telecom has deployed fiber-to-the-node and copper-based vectoring/pair bonding technology to increase data speeds reaching up to 100 Mbps.

Competition

TDS Telecom faces broadband, video, voice and wireless competition from wireline providers, cable providers, fiber overbuilders, VoIP providers, satellite providers, wireless providers and providers using other emerging technologies.

TDS Telecom continues to improve the efficiency of its cost structure to enhance its ability to compete with price-based initiatives from competitors. In addition to price, TDS Telecom competes based on a variety of factors including the reliability of its network, faster broadband speeds, the diversity and range of its product offerings and its focus on outstanding customer service.

TDS — REGULATION

TDS’ operations are subject to federal, state and local regulation. Key regulatory considerations are discussed below.

The construction, operation and transfer of wireless systems in the United States are regulated to varying degrees by the FCC pursuant to the Communications Act of 1934, as amended (Communications Act). The FCC currently does not require wireless carriers to comply with a number of statutory provisions otherwise applicable to common carriers that provide, originate or terminate interstate or international telecommunications. However, the FCC has enacted regulations governing construction and operation of wireless systems, licensing (including renewal of wireless spectrum licenses) and technical standards for the provision of wireless services under the Communications Act.

Wireless spectrum licenses segmented by geographic areas are granted by the FCC. The completion of acquisitions, involving the transfer of control of all or a portion of a wireless system, requires prior FCC approval. The FCC determines on a case-by-case basis whether an acquisition of wireless spectrum licenses is in the public interest. Wireless spectrum licenses are granted generally for a ten-year term or, in some cases, for a twelve-year or fifteen-year term. The FCC establishes the standards for conducting comparative renewal proceedings between a wireless license holder seeking renewal of its license and challengers filing competing applications. All of UScellular’s wireless spectrum licenses for which it applied for renewal since 1995 have been renewed. UScellular expects to continue to meet the criteria of the FCC’s license renewal process.

As part of its data services, UScellular provides internet access. Such internet access services may be subject to different regulatory requirements than other wireless services.

Although the Communications Act generally pre-empts state and local governments from regulating the entry of, or the rates charged by wireless carriers, certain state and local governments regulate other terms and conditions of wireless services, including billing, termination of service arrangements, imposition of early termination fees, advertising, network outages, the use of handsets while driving, zoning, land use, privacy, data security and consumer protection. Further, the Federal Aviation Administration also regulates the siting, lighting and construction of transmitter towers and antennae.

TDS Telecom

The FCC generally exercises jurisdiction over all facilities of, and services offered by, TDS Telecom’s Incumbent Local Exchange Carriers (ILEC) as telecommunications common carriers, to the extent they provide, originate or terminate interstate or international telecommunications. State public utility commissions generally exercise jurisdiction over intrastate telecommunications facilities and services. In addition, the ILECs are subject to various other state and local laws, including laws relating to privacy, data security and consumer protection.

The Communications Act requires, among other things, that telecommunications common carriers offer interstate services when requested at just and reasonable rates at terms and conditions that are non-discriminatory. Maximum rates for regulated interstate services are prescribed by the FCC. In many states, local rates paid by end user customers and intrastate access charges paid by carriers continue to be subject to state commission approval. The FCC regulations also cover matters such as technical operations, administrative requirements, consumer protection, access by people with disabilities, customer privacy and content.

TDS Telecom’s other operations are subject to similar but reduced regulation compared to ILECs.

Providing video services requires TDS Telecom to obtain franchises from state or local governmental authorities to occupy public rights of way with network facilities. These franchises are nonexclusive and typically limited in time, contain various conditions and limitations, and provide for the payment of fees to the local authority, determined generally as a standard percentage of revenues. TDS Telecom expects to continue to meet the criteria of the state or local government authorities' franchise renewal process.
