Those sections or portions of the registrant’s Notice of Annual Meeting of Shareholders and Proxy Statement (Proxy Statement) to be filed prior to April 29, 2024, for the 2024 Annual Meeting of Shareholders scheduled to be held May 21, 2024, are herein incorporated by reference into Parts II and III of this report.

United States Cellular Corporation (UScellular) provides wireless telecommunications services to customers with 4.6 million retail connections in portions of 21 states collectively representing a total population of 32 million. UScellular operates in one reportable segment, and all of its wireless operating markets are in the United States. UScellular is a majority-owned subsidiary of Telephone and Data Systems, Inc. As of December 31, 2023, TDS owns 83% of UScellular’s Common Shares, has the voting power to elect all of the directors of UScellular and controls 96% of the voting power in matters other than the election of directors of UScellular.

The map below highlights UScellular’s areas of operations.

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, 2023.

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. At this time, UScellular cannot predict the ultimate outcome of such process or estimate the potential impact of such process on the financial statements.

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, and investment interests. Additionally, UScellular may be engaged in negotiations related to wireless spectrum, including participation in Federal Communications Commission (FCC) auctions. The FCC has historically conducted auctions through which additional spectrum is made available for the provision of wireless services. Historically, UScellular has participated in certain FCC auctions both directly and indirectly through its limited partnership interests.

UScellular offers various service plans with nationwide coverage tailored to the needs of customers. Depending on those needs, service plans may include features related to, among other items: unlimited or metered voice and data; high-definition video features; the ability to use a device as a Wi-Fi hotspot; international voice, text, and data; and varying data rates depending on the plan and usage on that plan. Service offerings vary from time to time based on customer needs, technology changes and market conditions - and may be provided as standard plans or as part of limited time promotional offers.

UScellular offers home and business internet throughout the footprint via fixed wireless access. Options include an in-home self-installed device, a self-installation device mounted on the external side of a window, and externally-mounted professionally-installed equipment with an internal router. In addition to selling direct to businesses and residential homes, UScellular works with several municipalities to bring broadband internet to underserved communities.

UScellular offers advanced wireless solutions to consumers and business and government customers including an expansive suite of connected Internet of things (IoT) solutions and software applications across the categories of monitor and control (e.g., sensors and cameras), business automation/operations (e.g., e-forms, office solutions), communication (e.g., enterprise messaging, primary and back-up internet connectivity for business continuity), fleet and asset management, smart water solutions, private cellular networks (PCN) and custom, bespoke end-to-end IoT solutions et al. The business organization also offers a suite of professional and managed services. Lastly, for first responders, UScellular offers a suite of critical connectivity solutions that includes Wireless Priority Services (WPS) and Quality Priority and Preemption (QPP) options. UScellular intends to continue to further enhance these offerings in 2024 and beyond.

UScellular also offers services that enable customers to replace or repair their devices, including the Device Protection+ program, which provides as soon as next-day delivery of a replacement device for damaged, lost and stolen devices, and AppleCare services for Apple iOS customers. UScellular's Device Protection+ Advanced program also includes local or on-demand repair for eligible devices. In addition, UScellular offers a Trade-In program through which UScellular buys customers' used equipment.

UScellular purchases devices and accessory products from a number of original equipment manufacturers and distributors. UScellular manages relationships with its suppliers to ensure its customers have access to the industry's latest devices, to obtain best possible pricing, and to identify opportunities for promotional support from its suppliers. UScellular contracts with third-party providers for the majority of its product warehousing, distribution and direct customer fulfillment activities. UScellular also contracts with third-party providers for its device service programs.

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

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 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.

To expand its retail presence, UScellular also maintains a relationship with a large national retailer, selling postpaid and prepaid devices.

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, including 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, price, brand, size of area covered, 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.

5G technology helps address customers’ growing demand for data services and enhances 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. UScellular's initial 5G deployment has predominantly used low-band spectrum to launch 5G services in portions of substantially all its markets. During 2023, UScellular continued to invest in 5G with a focus on deployment of mid-band spectrum, which will largely overlap portions of areas already covered with low-band 5G service. 5G service deployed over mid-band spectrum will further enhance speed and capacity for UScellular's mobility and fixed wireless services.

UScellular also operates a VoLTE network, 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.

As a result of its continued investment and modernization of its network, UScellular decommissioned its third-generation (3G) CDMA network in the first quarter of 2024.

UScellular’s 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.

Reference is made to Item 7 of this Form 10-K under “Regulatory Matters” for information regarding any other significant recent developments and proposals relating to regulatory matters.

Competition in the wireless industry is intense and is expected to remain intense in the future due to multiple factors such as increasing market penetration, introduction of new products, new competitors, increasing promotional aggressiveness and changing prices. There is competition in service plan pricing; handsets and other devices; promotional discounts; network quality, coverage, speed and technologies, including 5G technology; distribution; new entrants; bundled services and products, such as content; and other categories. In particular, wireless competition includes aggressive service plan and device pricing, including pricing for unlimited plans, which could result in switching activity and churn and limit UScellular's ability to monetize future growth in data usage. In addition, competition based on network speed may increase as customer demand for higher speeds increases. These competitive factors have resulted in losses of retail connections and UScellular anticipates that they will continue to do so. Similarly, these competitive pressures have caused the prices for services and products to decline and the costs to compete to increase and UScellular anticipates that they will continue to do so.

UScellular’s competitors include national or global telecommunications and cable wireless companies that are larger than UScellular, possess greater financial and other resources, possess more extensive coverage areas and more spectrum within their coverage areas, and market other services with their communications services that UScellular does not offer. UScellular and its competitors are actively marketing their deployment of 5G and, as a result, are raising consumer awareness of the technology. If UScellular cannot keep pace with its competitors in deploying 5G or other comparable offerings, or if UScellular's deployment of 5G technology does not result in significant incremental revenues, UScellular's financial condition, results of operations and ability to do business could continue to be adversely affected. In addition, new technologies, services and products that are more commercially effective than the technologies, services and products offered by UScellular may be developed and create new sources of competition. Further, new technologies may be proprietary such that UScellular is not able to adopt such technologies. There can be no assurance that UScellular will be able to compete successfully in this environment. 

Sources of competition to UScellular’s business typically include at least four competing wireless telecommunications service providers across UScellular's service area, wireline telecommunications service providers, cable wireless companies, resellers (including MVNOs), and providers of alternative telecommunications services. In particular, competition from cable wireless companies has increased in recent periods, as they have continued to expand their presence in the wireless industry and have offered more competitive pricing. Many of UScellular’s wireless competitors and other competitors have substantially greater financial, technical, marketing, sales, purchasing and distribution resources than UScellular.

Competition in the tower industry is also challenging, as UScellular competes with public and private tower companies, wireless carrier tower alliances, private equity sponsored tower companies, and owners of non-communications sites such as utility towers, rooftop structures, water towers, and other alternative structures. Many of these competitors are larger than UScellular, have greater financial and other resources, have more advantageous tower locations than UScellular, have greater capacity on their towers, and have more scale and coverage nationwide than UScellular – such factors could result in an inability to acquire or build additional towers, difficulty in leasing tower space, or cause lease revenue to decline in the future.

UScellular’s service revenues include roaming revenues related to the use of UScellular’s network by other carriers’ customers who travel within UScellular’s coverage areas. Changes in FCC rules or actions, industry practices or the network footprints of carriers could have an adverse effect on UScellular’s roaming revenues. For example, the expansion of other carriers' network coverage in UScellular's footprint and/or lower roaming rates with other carriers could continue to decrease future roaming revenues for UScellular.

Similarly, UScellular's customers can access another carrier’s network automatically only if the other carrier allows UScellular's customers to roam on its network. UScellular relies on roaming agreements with other carriers to provide roaming capability to its customers and expand its product offerings in areas of the U.S. and internationally outside of its service areas and to improve coverage within selected areas of UScellular's network footprint. Although UScellular has entered into roaming agreements with national carriers, there is no assurance that UScellular will be able to maintain these agreements and/or enter into new agreements with other carriers to provide roaming services or that it will be able to do so on reasonable or cost-effective terms.

Some competitors may be able to obtain lower roaming rates than UScellular is able to obtain because they have larger data usage or call volumes or may be able to reduce roaming charges by providing service principally over their own networks. In addition, the quality and availability of services that a wireless carrier delivers to a UScellular customer while roaming may be inferior or limited in comparison to the service UScellular provides. UScellular’s rate of adoption of new technologies, such as those enabling high-speed data and voice services, could affect its ability to enter into or maintain roaming agreements with other carriers. In addition, UScellular’s wireless technology may not be compatible with technologies used by other carriers, which may limit the ability of UScellular to enter into voice or data roaming agreements with such other carriers. Carriers whose customers roam on UScellular’s network could switch their business to new operators, limit their high-speed usage or move traffic to their own networks. Changes in roaming usage patterns, rates for roaming usage, or roaming relationships with other carriers could continue to have an adverse effect on UScellular’s roaming revenues and/or expenses.

To the extent that other carriers expand their networks in UScellular’s service areas, the roaming arrangements between UScellular and these other carriers could become less strategic for them. That is, these other carriers will have fewer or less extensive geographic areas where roaming services are required by their customers and, as a result, the roaming arrangements could become less critical to serving their customer base. This presents a risk to UScellular in that, to the extent UScellular is not able to enter into economically viable roaming arrangements with these other carriers, this could impact UScellular’s ability to service its customers in geographic areas where UScellular does not have its own network.

UScellular’s business is highly technical and competition for skilled talent in the wireless industry is intense. Due to competition, limited supply, and/or rising wage levels for qualified management, technical, sales and other personnel, there can be no assurance that UScellular will be able to continue to attract and/or retain people of outstanding potential for the development of its business. In addition, a person's expectation of an in-office, remote or hybrid working model could negatively affect talent acquisition and retention. The loss of existing key personnel due to competition, wage levels and/or retirements, the failure to recruit highly skilled and diverse personnel in a timely and cost-effective manner, the inability to foster and maintain a diverse and inclusive work environment, or failure to maintain its commitment to environmental and social responsibility could have an adverse effect on UScellular’s business, financial condition or results of operations.

The market for highly skilled leaders in the wireless industry also is extremely competitive. The future success of UScellular and its business depends in substantial part on UScellular’s ability to recruit, hire, motivate, develop, and retain talented and highly skilled leaders for all areas of its organization. The loss of any of UScellular’s key leaders could have an adverse effect on its business, financial condition or results of operations. Effective succession planning is also important to UScellular’s long-term success. Failure to ensure effective transfer of knowledge and smooth transition involving key employees could also adversely affect UScellular’s business, financial condition and results of operations.

UScellular has smaller scale efficiencies compared to larger competitors. UScellular may be unable to compete successfully with larger companies that have substantially greater financial, technical, marketing, sales, purchasing and distribution resources or that offer more services than UScellular, which could adversely affect UScellular’s revenues and costs of doing business. Specifically, UScellular’s smaller scale relative to most of its competitors could have the following impacts, among others:

UScellular’s business depends on access to content for data and access to new wireless devices being developed by vendors. UScellular’s ability to obtain such access depends in part on other parties. If UScellular is unable to obtain timely access to new content or wireless devices being developed by vendors, its business, financial condition or results of operations could be adversely affected.

Changes in any of several factors could have an adverse effect on UScellular’s business, financial condition or results of operations. These factors include, but are not limited to:

UScellular’s business depends on the ability to use portions of the radio spectrum licensed by the FCC. UScellular could fail to obtain access to sufficient spectrum capacity, including spectrum needed to support 5G and future technologies, in new or existing markets, whether through FCC auctions or other transactions, to meet the anticipated spectrum requirements associated with increased demand for existing services, especially increases in customer demand for data services and network speed, and to enable deployment of next-generation services. UScellular believes that this increased demand for data services and network speed reflects a trend that will continue for the foreseeable future. Data usage, including usage under unlimited plans, could exceed current forecasts resulting in a need for increased investment in spectrum or other network components. UScellular could fail to accurately forecast its future spectrum requirements considering changes in plan offerings, customer usage patterns, spectrum build-out and technology requirements and the expanded demands of new services. Such a failure could have an adverse impact on the quality of UScellular’s services or UScellular’s ability to roll out such future services in some markets, could require that UScellular curtail existing services to make spectrum available for next-generation services, or UScellular could be effectively capped in increasing market share. As spectrum constrained providers gain customers, they use up their network capacity. Since they lack spectrum, they can respond to demand only by adding cell sites, which is capital intensive, adds fixed operating costs, is limited by zoning considerations, and ultimately may not be cost effective. Further, a spectrum constrained provider will generally not be able to achieve the data speeds that other competitors with more spectrum are able to provide.

UScellular may acquire access to spectrum through a number of alternatives, including acquisitions, exchanges and participation in spectrum auctions. UScellular may participate in spectrum auctions conducted by the FCC in the future. As required by law, the FCC has conducted auctions for wireless spectrum licenses to use some parts of the radio spectrum. The decision to conduct auctions, and the determination of what spectrum frequencies will be made available for auction and the determination of geographic size of wireless spectrum licenses, are made by the FCC pursuant to laws that it administers. The FCC currently does not have authority to conduct spectrum auctions. The FCC may not be able to allocate spectrum sufficient to meet the demands of all those wishing to obtain wireless spectrum licenses for new market entry or to expand their spectrum holdings to meet the expanding demand for data services or to address other spectrum constraints. Due to factors such as geographic size of wireless spectrum licenses and auction bidders that may raise prices beyond acceptable levels, UScellular may not be successful in FCC auctions in obtaining access to the spectrum that it believes is necessary to implement its business and technology strategies.

Access to wireless spectrum licenses won in FCC auctions may not be available on a timely basis. Such access is dependent upon the FCC actually granting wireless spectrum licenses won, which can be rescinded or delayed for various reasons, including but not limited to exceeding spectrum ownership and attribution limits, and safety concerns due to interference with other spectrum bands. Furthermore, newly licensed spectrum may not be available for immediate use since the radio operations of incumbent users, including in some cases government agencies, may need to be relocated to other portions of the radio spectrum, and/or the newly licensed spectrum may be subject to sharing and coordination obligations. UScellular also may seek to acquire radio spectrum through purchases and exchanges with other spectrum licensees. However, UScellular may not be able to acquire sufficient spectrum through these types of transactions, and UScellular may not be able to complete any of these transactions on favorable terms.

The telecommunications industry is experiencing significant changes in technologies and services expected by customers, as evidenced by evolving industry standards, ongoing improvements in the capacity and quality of digital technology, shorter development cycles for new services and products, and enhancements and changes in end-user requirements and preferences. Advances in technology could change the amount of tower space needed by wireless companies. Further, fixed-mobile bundled services that combine wireline broadband services with mobile services represent a competitive threat. If the trend toward bundling continues, UScellular is at a competitive disadvantage compared to larger competitors, including cable companies, the national wireless carriers and other potential large new entrants with much greater financial and other resources in adapting to such bundling. Future technological changes or advancements may enable other wireless technologies to equal or exceed UScellular’s current levels of service and render its system infrastructure obsolete. UScellular may not be able to respond to such changes and implement new technology on a timely or cost-effective basis, which could reduce its revenues or increase its costs of doing business.

UScellular is deploying 5G technology in its network and has launched commercial 5G services in portions of substantially all of its markets. The continued deployment of 5G technology will require substantial additional investments in UScellular's wireless networks to remain competitive in the industry. Transition to 5G or other new technologies involves significant time, cost and risk, and anticipated products and revenues may not be realized. Furthermore, the wireless business experiences rapid technology changes and new services and products. If UScellular fails to effectively deploy new wireless technologies, services or products on a timely basis, this could have an adverse impact on UScellular’s business, financial condition and results of operations.

Furthermore, it is not certain that UScellular’s investments in various new, unproven technologies and the related service and product offerings will be effective. The markets for some of these services, products and solutions may still be emerging and the overall potential for these markets, including revenues to be realized, may be uncertain. If customer demand for these new services, products and solutions does not develop as expected, UScellular’s business, financial condition or results of operations could be adversely affected.

As part of UScellular’s operating strategy, UScellular from time to time may be engaged in the acquisition, divestiture or exchange of companies, businesses, strategic properties, wireless spectrum or other assets. UScellular may change the markets in which it operates and the services that it provides through such acquisitions, divestitures and/or exchanges. In general, UScellular may not disclose the negotiation of such transactions until a definitive agreement has been reached.

These transactions commonly involve a number of risks, including:

No assurance can be given that UScellular will be successful with respect to its acquisition, divestiture or exchange strategies or initiatives.

UScellular’s business plan includes significant construction activities and enhancements to its network, support and other systems and infrastructure. Additionally, the deployment of new wireless technologies, including 5G, will require substantial investments in UScellular's wireless network. As UScellular deploys, expands and enhances its network, it may need to acquire additional spectrum. Also, as UScellular continues to build out and enhance its network, UScellular must, among other things, continue to:

Any difficulties encountered in completing these activities, as well as problems in vendor equipment availability, labor availability, inflation or other pressures on costs, technical resources, system performance or system adequacy, could delay implementation and deployment of new technologies, delay expansion of operations and product capabilities in new or existing markets or result in increased costs. Failure to successfully deploy new technologies, including 5G, and/or build-out and enhance UScellular’s network, support facilities and other systems and infrastructure in a cost-effective manner, and in a manner that satisfies consumers' expectations for quality and coverage, could have an adverse effect on UScellular’s business, business prospects, financial condition or results of operations.

UScellular has relationships with independent agents and third-party national retailers who market UScellular services.

UScellular depends upon certain vendors to provide it with equipment, services and content that meet its quality and cost requirements on a timely basis to continue its network construction and upgrades, and to operate its business. UScellular depends upon certain vendors to provide it with wireless devices that meet its quality and cost requirements on a timely basis to support sales. UScellular does not have operational or financial control over such key suppliers and has limited influence with respect to the manner in which these key suppliers conduct their businesses. Further, key suppliers may experience supply chain challenges beyond their control that result in difficulties providing the services and products typically requested by UScellular on a timely basis. If these key suppliers (i) experience product availability shortages, (ii) require extended lead times to fulfill orders, (iii) experience financial difficulties or file for bankruptcy or experience other operational difficulties or (iv) deem UScellular non-strategic and do not develop or sell services and products to UScellular, particularly where technical requirements differ from those of larger companies, they may not provide equipment, services or content to UScellular on a timely basis, or at all, or they may otherwise fail to honor their obligations to UScellular. Furthermore, consolidation among key suppliers may result in less competition, higher prices, the discontinuation of equipment and/or services typically purchased by UScellular or the discontinuation of support for equipment owned by UScellular.

Operation of UScellular’s supply chain and management of its device inventory and network equipment require accurate forecasting of customer growth and demand. If overall demand for wireless devices or the mix of demand for wireless devices is significantly different than UScellular’s expectations, UScellular could face inadequate or excess supplies of particular models of wireless devices. This could result in lost sales opportunities or an excess supply of device inventory or network equipment that may need to be written down, depreciated, or disposed of for a loss. If network equipment is not available or requires extended lead times due to supply chain challenges, or if overall demand for wireless services or the mix of demand for wireless services is significantly different than UScellular’s expectations, UScellular may not be able to adequately maintain a network that supports customer demand. Further, UScellular's supply chain could be disrupted unexpectedly by raw material shortages, wars, natural disasters, disease or other factors. Supply chain disruptions may result in limited component availability, constraints on certain devices, extended lead times, delayed construction and additional uncertainty.

Also, UScellular has other arrangements with third parties, including arrangements pursuant to which UScellular outsources certain support functions to third-party vendors. Operational problems associated with such functions, including any failure by the vendor to provide the required level of service under the outsourcing arrangements, including possible cyber-attacks or other breaches of network or information technology security, data protection or privacy, could have adverse effects on UScellular’s business, financial condition or results of operations.

UScellular relies extensively on its telecommunication networks and information technologies to operate and manage its business, process transactions and summarize and report results. These networks and technologies are subject to obsolescence and, consequently, must be upgraded, replaced and/or otherwise enhanced over time. Enhancements must be more flexible and dependable than ever before. All of this is capital intensive and challenging.

The increased provision of data services has introduced significant demands on UScellular’s network and also has increased complexities related to network management, which creates an increased level of risk related to quality of service and data speeds. This is due to the fact that many customers increasingly rely on data communications to execute and validate transactions. As a result, redundancy and geographical diversity of UScellular’s network facilities are critical to providing uninterrupted service. Also, the speed of repair and maintenance procedures in the event of network interruptions is critical to maintaining customer satisfaction. UScellular’s ability to maintain high-quality, uninterrupted service to its customers is critical, particularly given the increasingly competitive environment and customers’ ability to choose other service providers. 

In addition, UScellular’s networks and information technologies and the networks and information technologies of vendors on which UScellular relies are subject to damage or interruption due to various events, including power outages, computer, network and telecommunications failures, computer viruses, security breaches, hackers and other cyber security risks, catastrophic events, natural disasters, severe weather, adverse climate changes, errors or unauthorized actions by employees and vendors, flawed conversion of systems, disruptive technologies and technology changes. 

UScellular operates a capital-intensive business. Historically, UScellular has used internally-generated funds and also has obtained substantial funds from external sources for general corporate purposes. In the past, UScellular’s existing cash and investment balances, funds available under its financing agreements, and cash flows from operating and certain investing and financing activities, including sales of assets or businesses, provided sufficient liquidity and financial flexibility for UScellular to meet its normal day-to-day operating needs and debt service requirements, to finance the build-out and enhancement of markets and to fund wireless spectrum license acquisitions. There is no assurance that this will be the case in the future. It may be necessary from time to time to increase the amount of permissible borrowings under its financing agreements, to put in place new credit agreements, or to obtain other forms of financing to fund potential expenditures. UScellular’s liquidity would be adversely affected if, among other things, cash flows from operations significantly decline, UScellular is unable to obtain short or long-term financing on acceptable terms, UScellular is not able to comply with certain debt covenants or UScellular is unsuccessful in negotiating related consents, waivers, or amendments, interest rates increase, UScellular makes significant spectrum license purchases, UScellular makes significant capital investments, UScellular makes significant business acquisitions, the Los Angeles SMSA Limited Partnership (LA Partnership) and other minority-owned partnerships discontinue or significantly reduce distributions compared to historical levels, or Federal USF and/or other regulatory support payments decline. UScellular's liquidity may also be adversely affected by changes in the liquidity of TDS that impact TDS' or UScellular's ability to comply with certain debt covenants or if TDS or UScellular is unsuccessful in negotiating related consents, waivers, or amendments. These or other developments at TDS may negatively affect UScellular's ability to obtain short or long-term financing on acceptable terms or obtain favorable terms and conditions from third-party vendors.

UScellular’s credit rating currently is sub-investment grade. UScellular has incurred negative free cash flow (defined as Cash flows from operating activities less Cash paid for additions to property, plant and equipment and less Cash paid for software license agreements) at times in the past and this could occur in the future. UScellular may require substantial additional capital for, among other uses, acquisitions of providers of telecommunications services or products, spectrum license or system acquisitions, capital expenditures, the repurchase of shares, or making additional investments. There can be no assurance that sufficient funds will continue to be available to UScellular or its subsidiaries on terms or at prices acceptable to UScellular. Insufficient cash flows from operating activities, changes in UScellular's credit ratings, defaults of the terms of debt or credit agreements, uncertainty of access to capital, deterioration in the capital markets, reduced regulatory capital at banks which in turn limits their ability to lend, other changes in the performance of UScellular or in market conditions or other factors could limit or restrict the availability of financing on terms and prices acceptable to UScellular, which could require UScellular to reduce its acquisition, capital expenditure and business development programs, reduce the acquisition and development of wireless spectrum licenses, divest assets and/or reduce or cease share repurchases. UScellular cannot provide assurance that circumstances that could have a material adverse effect on its liquidity or capital resources will not occur.

TDS’ credit rating from nationally recognized credit agencies may impact UScellular’s credit rating as, given UScellular’s ownership structure, the rating agencies often consider rating actions related to TDS and UScellular in tandem. To the extent that TDS' credit rating is downgraded, it may adversely affect UScellular's credit rating, which could result in the impacts described above.

UScellular has a significant amount of indebtedness and may need to incur additional indebtedness. UScellular’s level of indebtedness could have important consequences. For example, it (i) may limit UScellular’s ability to obtain additional financing for working capital, capital expenditures or general corporate purposes, particularly if the ratings assigned to its debt securities by rating organizations are revised downward; (ii) will require UScellular to dedicate a substantial portion of its cash flow from operations to the payment of interest and principal on its debt, thereby reducing the funds available to UScellular for other purposes including expansion through acquisitions, capital expenditures, acquisition of wireless spectrum licenses, marketing spending and expansion of its business; and (iii) may limit UScellular’s flexibility to adjust to changing business and market conditions and make UScellular more vulnerable to a downturn in general economic conditions as compared to UScellular’s competitors. UScellular’s ability to make scheduled payments on its indebtedness or to refinance it will depend on its financial and operating performance which, in turn, is subject to prevailing economic and competitive conditions and other factors beyond its control. A substantial portion of UScellular's debt is subject to variable interest rates, which has increased interest expense in recent periods and UScellular will continue to be vulnerable to unfavorable changes in market interest rates.

UScellular’s revolving credit agreement, term loan agreement, export credit financing agreement and receivables securitization agreement require UScellular to comply with certain affirmative and negative covenants, including certain financial covenants. Depending on the actual financial performance of UScellular, there is a risk that UScellular could fail to satisfy the required financial covenants. This risk has increased with UScellular's recent financial and operating performance. If UScellular breaches a financial or other covenant of any of these agreements, it would result in a default under that agreement, and could involve a cross-default under other debt instruments. This could in turn cause the affected lenders to accelerate the repayment of principal and accrued interest on any outstanding debt under such agreements and, if they choose, terminate the agreement. If appropriate, UScellular may request an amendment to one or more credit agreements to adjust financial covenants to provide additional financial flexibility to UScellular, and may also seek other changes to such agreements. There is no assurance that the lenders will agree to any amendments. If the lenders agree to amendments, this may result in additional payments or higher interest rates payable to the lenders and/or additional restrictions. Restrictions with such debt instruments may limit UScellular’s operating and financial flexibility.

As a result, UScellular’s level of indebtedness, restrictions contained in debt instruments and/or possible breaches of covenants, defaults, and acceleration of indebtedness could have an adverse effect on UScellular’s business, financial condition, revenues, results of operations and cash flows.

The U.S. wireless telecommunications industry is facing significant change and an uncertain operating environment. UScellular’s focus on the U.S. wireless telecommunications industry, together with its sub-scale position relative to larger competitors with greater resources within the industry, may represent increased risk for investors due to the lack of diversification. This could have an adverse effect on UScellular’s ability to attain and sustain long-term, profitable revenue growth and could have an adverse effect on its business, financial condition or results of operations.

UScellular has significant investments in entities that it does not control, including equity investments and interests in certain variable interest entities. UScellular’s interests in such entities do not provide UScellular with control over the business strategy, financial goals, network build-out plans or other operational aspects of these entities. UScellular cannot provide assurance that these entities will operate in a manner that will increase or maintain the value of UScellular’s investments, that UScellular’s proportionate share of income from these investments will continue at the current level in the future or that UScellular will not incur losses from the holding of such investments. Losses in the values of such investments or a reduction in income from these investments could adversely affect UScellular’s financial condition or results of operations. In addition, certain investments have historically contributed significant cash flows to UScellular and a reduction or suspension of such cash flows could adversely affect UScellular’s financial condition.

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. This comprehensive process could result in a diversion of management's attention from UScellular's existing business; a failure to achieve financial and operating objectives; the failure to retain key personnel, customers, business partners or contracts; and volatility in UScellular's stock price. In addition, this process has already resulted in the incurrence of significant expense - this is expected to continue. It is possible that any outcomes of the strategic alternatives review could change the composition of UScellular's long-lived assets, how UScellular may derive cash flows from these assets and may result in uncertainty related to asset recoverability. This may impact UScellular's asset groups for purposes of assessing wireless spectrum licenses and/or property, plant and equipment for impairment and may require in the near term an impairment assessment to be performed which may result in an impairment. There can be no assurance that such comprehensive process will result in any strategic alternative of any kind being successfully identified or completed or that the process or any outcomes of the process will not have an adverse impact on UScellular's business or financial statements.

UScellular’s operations are subject to varying degrees of regulation by the FCC, state public utility commissions and other federal, state and local regulatory agencies and legislative bodies. Various regulatory agencies and legislative bodies could implement different policies with respect to many federal laws and regulations, including but not limited to changes to fiscal and tax policies, trade policies, tariffs on import goods and climate change. New or amended regulatory requirements could increase UScellular’s costs and divert resources from other initiatives. Adverse decisions, increased regulation, or changes to existing regulation by regulatory bodies could negatively impact UScellular’s operations by, among other things, restricting energy consumption or access to grid electricity, permitting greater competition or limiting UScellular’s ability to engage in certain sales or marketing activities, or retention and recruitment of skilled resources. New regulatory mandates or enforcement may require unexpected or increased capital expenditures, lost revenues, higher operating expenses or other changes. Court decisions and rulemakings could have a substantial impact on UScellular’s operations, including rulemakings on broadband access to the internet, intercarrier access compensation, state and federal support funding and court decisions regarding the FCC's universal service fund program or, more broadly, the scope of authority of the federal agencies that regulate UScellular. Litigation and different objectives among federal and state regulators could create uncertainty and delay UScellular’s ability to respond to new regulations. Further, wireless spectrum licenses are subject to renewal by the FCC and could be revoked in the event of a violation of applicable laws or regulatory requirements. Also, although FCC rules relating to net neutrality have been repealed, on October 19, 2023, the FCC adopted a draft Notice of Proposed Rulemaking (NPRM) that proposes to reinstate such rules and reclassify broadband internet access service as a telecommunications service under Title II of the Communications Act of 1934. In the interim, some state legislators and regulators are seeking to or have already enacted state net neutrality laws and regulations, and it is unclear whether more states will seek to do so now that the FCC has announced its intent to reinstate net neutrality rules. Interpretation and application of these rules and of rules relating to other recent NPRMs issued by the FCC (for example, with respect to digital discrimination), including conflicts between federal and state laws, may result in additional costs for compliance and may limit opportunities to derive profits from certain business practices or resources.

UScellular attempts to timely and fully comply with all regulatory requirements. However, UScellular is unable to predict the future actions of the various legislative and regulatory bodies that govern UScellular, and such actions could have adverse effects on UScellular’s business.

Telecommunications companies may be designated by states, or in some cases by the FCC, as an Eligible Telecommunications Carrier (ETC) to receive universal service support payments if they provide specified services in “high-cost” areas. UScellular has been designated as an ETC in certain states and received $92 million in high-cost support for service to high-cost areas in 2023. While there is uncertainty, UScellular expects that regulatory support payments will likely decline in future periods, and there is no assurance that UScellular will qualify for future regulatory support programs. If regulatory support is discontinued or reduced from current levels, or if receipt of future regulatory support is contingent upon making certain network-related expenditures, this could have an adverse effect on UScellular’s business, financial condition or operating results and cash flows. Adding to this uncertainty are a series of court cases challenging the constitutionality of the universal service fund program that establishes and administers these regulatory support payments.

Telecommunications providers pay a variety of surcharges and fees on their gross revenues from interstate and intrastate services, including USF fees and common carrier regulatory fees. The division of services between interstate services and intrastate services, including the divisions associated with Federal USF fees, is a matter of interpretation and in the future may be contested by the FCC or state authorities. The FCC in the future also may change the basis on which Federal USF fees are charged. The Federal government and many states also apply transaction-based taxes to sales of telecommunications services and products and to purchases of telecommunications services from various carriers. In addition, state regulators and local governments have imposed and may continue to impose various surcharges, taxes and fees on telecommunications services. The applicability of these surcharges and fees to UScellular’s services is uncertain in many cases and jurisdictions may contest whether UScellular has assessed and remitted those monies correctly. Periodically, state and federal regulators may increase or change the surcharges and fees UScellular currently pays. In some instances, UScellular passes through these charges to its customers. However, Congress, the FCC, state regulatory agencies or state legislatures may limit the ability to pass through transaction-based tax liabilities, regulatory surcharges and regulatory fees imposed on UScellular to customers. UScellular may or may not be able to recover some or all of those taxes from its customers and the amount of taxes may deter demand for its services or increase its cost to provide service. 

UScellular is regularly involved in a number of legal and policy proceedings before the FCC and various state and federal courts. Such legal and policy proceedings can be complex, costly, protracted and highly disruptive to business operations by diverting the attention and energies of management and other key personnel.

The assessment of legal and policy proceedings is a highly subjective process that requires judgments about future events. Additionally, amounts ultimately received or paid upon settlement or resolution of litigation and other contingencies may differ materially from amounts accrued in the financial statements. Depending on a range of factors, these or similar proceedings could impose restraints on UScellular’s current or future manner of doing business.

Media reports and certain professional studies have suggested that certain potentially harmful emissions from devices or network equipment, including but not limited to radio frequencies emitted by wireless signals, may cause harmful health or environmental consequences, including cancer, tumors or otherwise harmful impacts, and may interfere with various electronic medical devices, including hearing aids and pacemakers. There may also be safety concerns related to frequencies used by wireless devices interfering with frequencies used by other industries, including but not limited to, the concerns of the Federal Aviation Administration regarding potential interference of 5G deployment with altimeters used by aircraft, which could impact deployment of certain wireless spectrum. UScellular is a party to and may in the future be a party to lawsuits against wireless carriers and other parties claiming damages for alleged health effects, including cancer or tumors, arising from wireless phones, radio frequency transmitters, or harmful emissions from network equipment. Concerns over radio frequency emissions may discourage use of wireless devices or expose UScellular to potential litigation. In addition, the FCC or other regulatory authorities may adopt regulations in response to concerns about radio frequency or harmful network equipment emissions. Any resulting decrease in demand for wireless services, costs of litigation and damage awards or regulation could have an adverse effect on UScellular’s business, financial condition or results of operations.

In addition, some studies have indicated that some aspects of using a wireless device while driving may impair a driver's attention in certain circumstances, making accidents more likely. These concerns could lead to potential litigation relating to accidents, deaths or serious bodily injuries.

UScellular faces possible effects of industry litigation relating to patents, other intellectual property or otherwise, that may restrict UScellular’s access to devices or network equipment critical to providing services to customers. If technology that UScellular uses in products or services were determined by a court to infringe a patent or other intellectual property right held by another person, UScellular could be precluded from using that technology and could be required to pay significant monetary damages. UScellular also may be required to pay significant royalties to such person to continue to use such technology in the future. The successful enforcement of any intellectual property rights, or UScellular’s inability to negotiate a license for such rights on acceptable terms, could force UScellular to cease using the relevant technology and offering services incorporating the technology. Any litigation to determine the validity of claims that UScellular’s products or services infringe or may infringe intellectual property rights of another, regardless of their merit or resolution, could be costly and divert the effort and attention of UScellular’s management and technical personnel. Regardless of the merits of any specific claim, UScellular cannot give assurance that it would prevail in litigation because of the complex technical issues and inherent uncertainties in intellectual property litigation. Although UScellular generally seeks to obtain indemnification agreements from vendors that provide it with technology, there can be no assurance that any claim of infringement will be covered by an indemnity or that UScellular will be able to recover all or any of its losses and costs under any available indemnity agreements. Any claims of infringement of intellectual property and proprietary rights of others could prevent UScellular from using necessary technology to provide its services or subject UScellular to expensive intellectual property litigation or monetary penalties.

TDS owns over 80% of the combined shares outstanding of both classes of common stock of UScellular, including a majority of the outstanding Common Shares and 100% of the Series A Common Shares, and controls 96% of their combined voting power. As a result, TDS is effectively able to elect all of UScellular’s thirteen directors and otherwise control the management and operations of UScellular. Seven of the thirteen directors of UScellular are also directors of TDS and/or executive officers of TDS and/or UScellular. Directors and officers of TDS who are also directors or officers of UScellular, and TDS as UScellular’s controlling shareholder, are in positions involving the possibility of conflicts of interest with respect to certain transactions concerning UScellular. When the interests of TDS and UScellular diverge, TDS may exercise its influence in its own best interests.

UScellular and TDS have entered into contractual arrangements governing certain transactions and relationships between them. Some of these agreements were executed prior to the initial public offering of UScellular’s Common Shares and were not the result of arm’s-length negotiations. Accordingly, there is no assurance that the terms and conditions of these agreements are as favorable to UScellular as could have been obtained from unaffiliated third parties. See “Certain Relationships and Related Transactions” in this Form 10-K.

Conflicts of interest may arise between TDS and UScellular when faced with decisions that could have different implications for UScellular and TDS, including technology decisions, financial decisions, the payment of distributions by UScellular, agreements or transactions between TDS and UScellular, business activities and other matters. TDS also may take action that favors its other businesses and the interests of its shareholders over UScellular’s wireless business and the interests of UScellular shareholders and debt holders. Because TDS controls UScellular, conflicts of interest could be resolved in a manner adverse to UScellular and its other shareholders or its debt holders.

The UScellular Restated Certificate of Incorporation provides that, so long as not less than 500,000 Series A Common Shares are outstanding, UScellular, without the written consent of TDS, shall not, directly or indirectly own, invest or otherwise have an interest in, lease, operate or manage any business other than a business engaged solely in the construction of, the ownership of interests in and/or the management of wireless telephone systems. This limitation on the scope of UScellular’s potential business could hurt the growth of UScellular’s business. This restriction would preclude UScellular from pursuing attractive related or unrelated business opportunities unless TDS consents in writing. TDS has no obligation to consent to any business opportunities proposed by UScellular and may withhold its consent in its own best interests.

The control of UScellular by TDS may tend to deter non-negotiated tender offers or other efforts to obtain control of UScellular and thereby deprive shareholders of opportunities to sell shares at prices higher than those prevailing in the market.

The UScellular Restated Certificate of Incorporation also contains provisions which may serve to discourage or make more difficult a change in control of UScellular without the support of TDS or without meeting various other conditions. In particular, the authorization of multiple classes of capital stock with different voting rights could prevent shareholders from profiting from an increase in the market value of their shares as a result of a change in control of UScellular by delaying or preventing such change in control.

The UScellular Restated Certificate of Incorporation also authorizes the UScellular Board of Directors to designate and issue Preferred Shares in one or more classes or series from time to time. Generally, no further action or authorization by the shareholders is necessary prior to the designation or issuance of the additional Preferred Shares authorized pursuant to the UScellular Restated Certificate of Incorporation unless applicable laws or regulations would require such approval in a given instance. Such Preferred Shares could be issued in circumstances that would serve to preserve TDS’ control of UScellular.

The provisions of the UScellular Restated Certificate of Incorporation and the existence of different classes of capital stock and voting rights could result in the exclusion of UScellular Common Shares from certain major stock indices at some point in the future, unless UScellular is grandfathered by such stock indices or qualifies for some other exception.

UScellular experiences cyber-attacks of varying degrees on a regular basis. These include cyber-attacks intended to wrongfully obtain private and valuable information, or cause other types of malicious events, including denial of service attacks which may cause UScellular's services to be disrupted or unavailable to customers. The increased number of associates working remotely increases risks associated with data handling and vulnerability management. The rapid evolution and increased adoption of artificial intelligence technologies may intensify UScellular's cybersecurity risk. UScellular maintains administrative, technical and physical controls, as well as other preventative actions, to reduce the risk of security breaches. Although to date UScellular has not discovered a material security breach, these efforts may be insufficient to prevent a material security breach stemming from future cyber-attacks including ransomware. If UScellular’s or its vendors’ networks and information technology are not adequately adapted to changes in technology or are damaged or fail to function properly, and/or if UScellular’s or its vendors’ security is breached or otherwise compromised, UScellular could suffer adverse consequences, including theft, destruction or other loss of critical and private data, including customer and/or employee data, interruptions or delays in its operations, inaccurate billings, inaccurate financial reporting, and significant costs to remedy the problems. If UScellular’s or its vendors’ systems become unavailable or suffer a security breach of customer or other data, UScellular may be required to expend significant resources and take various actions to address the problems, including notification under data privacy laws and regulations, may be subject to fines, sanctions and litigation, and its reputation and operating results could be adversely affected. UScellular continues to experience denial of service attacks. Although UScellular has implemented and continues to enhance its protection and recovery measures in response to such attacks, these efforts may be insufficient to prevent a material denial of service attack in the future. See Item 1C. Cybersecurity of this Form 10-K for additional information.

Disruptions in the credit and financial markets, declines in consumer confidence, increases in unemployment, declines in economic growth, increased tariffs on import goods, sudden increases in inflation and uncertainty about corporate earnings could have a significant negative impact on the U.S. and global financial and credit markets and the overall economy. Such events could have an adverse impact on financial institutions resulting in limited access to capital and credit for many companies. Furthermore, economic uncertainties make it very difficult to accurately forecast and plan future business activities. Changes in economic conditions, changes in financial markets, changes in U.S. trade policies, deterioration in the capital markets or other factors could have an adverse effect on UScellular’s business, financial condition, revenues, results of operations and cash flows.

None.

UScellular’s Information Technology Security leaders are responsible for assessing and managing cybersecurity risks. Management has a depth of cybersecurity experience focused on increasing the organization's resilience to security threats and stays current on new developments through continuing education and monitoring of the cybersecurity landscape. The UScellular environment is monitored for potential security threats and security events are investigated and acted on to minimize potential risk to the environment.

The full Board of Directors engages in oversight of UScellular's cybersecurity risks. The Board of Directors receives regular updates from management on technology and security updates and UScellular’s assessment of cybersecurity threats and mitigation plans. The UScellular Audit Committee oversees the processes over internal controls and financial reporting that includes controls and procedures that are designed to ensure that significant cybersecurity incidents are communicated to both senior management and the Audit Committee. Cybersecurity is also discussed with the Technology Advisory Group of the Board of Directors as warranted, at least on an annual basis.

As of December 31, 2023, UScellular’s gross investment in property, plant and equipment was $9,560 million.

UScellular is involved or may be involved from time to time in legal proceedings before the FCC, other regulatory authorities, and/or various state and federal courts. If UScellular believes that a loss arising from such legal proceedings is probable and can be reasonably estimated, an amount is accrued in the financial statements for the estimated loss. If only a range of loss can be determined, the best estimate within that range is accrued; if none of the estimates within that range is better than another, the low end of the range is accrued. The assessment of the expected outcomes of legal proceedings is a highly subjective process that requires judgments about future events. The legal proceedings are reviewed at least quarterly to determine the adequacy of accruals and related financial statement disclosures. The ultimate outcomes of legal proceedings could differ materially from amounts accrued in the financial statements. See Note 13 — Commitments and Contingencies in the Notes to Consolidated Financial Statements for further information.

Not applicable.

UScellular's Common Shares are listed on the New York Stock Exchange under the symbol "USM." As of January 31, 2024, the last trading day of the month, UScellular's Common Shares were held by 224 record owners. All of the Series A Common Shares were held by TDS. No public trading market exists for the Series A Common Shares. The Series A Common Shares are convertible on a share-for-share basis into Common Shares.

UScellular has not paid any cash dividends in recent periods and currently intends to retain all earnings for use in UScellular’s business. UScellular cannot predict whether the outcome of the ongoing process to explore a range of strategic alternatives that UScellular and TDS announced on August 4, 2023 or other factors would impact such intention.

The comparison above assumes $100.00 invested at the close of trading on the last trading day of 2018, in UScellular Common Shares, S&P 500 Index and the Dow Jones U.S. Telecommunications Index.

In November 2009, UScellular announced by Form 8-K that the Board of Directors of UScellular authorized the repurchase of up to 1,300,000 Common Shares on an annual basis beginning in 2009 and continuing each year thereafter, on a cumulative basis. In December 2016, the UScellular Board of Directors amended this authorization to provide that, beginning on January 1, 2017, the authorized repurchase amount with respect to a particular year will be any amount from zero to 1,300,000 Common Shares, as determined by the Pricing Committee of the Board of Directors, and that if the Pricing Committee did not specify an amount for any year, such amount would be zero for such year. The Pricing Committee has not specified any increase in the authorization since that time. The Pricing Committee also was authorized to decrease the cumulative amount of the authorization at any time, but has not taken any action to do so at this time. The authorization provides that share repurchases will be made pursuant to open market purchases, block purchases, private purchases, or otherwise, depending on market prices and other conditions. This authorization does not have an expiration date. UScellular did not determine to terminate the foregoing Common Share repurchase program, as amended, or cease making further purchases thereunder, during the fourth quarter of 2023.

UScellular owns, operates, and invests in wireless markets throughout the United States. UScellular is an 83%-owned subsidiary of Telephone and Data Systems, Inc. (TDS).

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:

On August 4, 2023, TDS and UScellular announced that the Boards of Directors of both companies have decided to initiate a process to explore a range of strategic alternatives for UScellular. During 2023, UScellular incurred third-party expenses of $8 million related to the strategic alternatives review. At this time, UScellular cannot predict the ultimate outcome of such process or estimate the potential impact of such process on the financial statements.

The following is a list of definitions of certain industry terms that are used throughout this document:

Total postpaid handset net losses increased in 2023 due primarily to lower gross additions resulting from aggressive industry-wide competition.

Total postpaid connected device net additions increased in 2023 due primarily to higher demand for fixed wireless home internet as well as decreases in tablet and mobile hotspot churn.

Postpaid ARPU increased in 2023 due to favorable plan and product offering mix and an increase in device protection plan revenues, partially offset by an increase in promotional discounts.

Postpaid ARPA was relatively flat in 2023 due to the impacts to Postpaid ARPU, offset by a decrease in the number of connections per account.

Retail service revenues decreased in 2023 primarily as a result of a decrease in average postpaid and prepaid connections, partially offset by an increase in Postpaid ARPU as previously discussed in the Operational Overview section.

Inbound roaming revenues decreased in 2023, primarily driven by lower data revenues resulting from lower rates.

Equipment sales revenues decreased in 2023, due primarily to a decline in smartphone upgrades and gross additions, partially offset by a higher average price of new smartphone sales.

Wireless service providers have been aggressive promotionally and on price to attract and retain customers. This includes both traditional carriers and cable companies operating as mobile virtual network operators (MVNOs). UScellular expects promotional aggressiveness by traditional carriers and pricing pressures from cable companies to continue into the foreseeable future. Operating revenues and Operating income have been negatively impacted in current and prior periods, and may be negatively impacted in future periods, by competitive promotional offers to new and existing customers.

Total operating expenses in 2023 include $9 million of severance and related expenses associated with a reduction in workforce that was recorded in the first quarter of 2023. These severance expenses are included in System operations expenses and Selling, general and administrative expenses.

System operations expenses decreased in 2023, due primarily to decreases in roaming and customer usage expenses, partially offset by an increase in maintenance, utility, and cell site expenses. The decrease in roaming expense was driven by a decrease in roaming rates partially offset by an increase in usage.

Cost of equipment sold decreased in 2023, due primarily to a decline in smartphone upgrades and gross additions, partially offset by a higher average cost per unit sold.

Selling, general and administrative expenses decreased in 2023, due primarily to decreases in bad debts expense, commissions, facilities and employee-related expenses, partially offset by an increase in advertising expenses as well as $8 million of expenses related to the strategic alternatives review.

Depreciation, amortization and accretion expenses decreased in 2023 due primarily to enhancements that extended the useful life of a software platform.

Interest expense increased in 2023 due primarily to interest rate increases on variable rate debt. See Market Risk for additional information regarding maturities of long-term debt and weighted average interest rates.

Income tax expense increased in 2023 due primarily to the increase in Income before income taxes.

See Note 5 — Income Taxes in the Notes to Consolidated Financial Statements for additional information.

UScellular operates a capital-intensive business. In the past, UScellular’s existing cash and investment balances, funds available under its financing agreements, and cash flows from operating and certain investing and financing activities, including sales of assets or businesses, provided sufficient liquidity and financial flexibility for UScellular to meet its day-to-day operating needs and debt service requirements, to finance the build-out and enhancement of markets and to fund wireless spectrum license acquisitions. There is no assurance that this will be the case in the future. UScellular has incurred negative free cash flow at times in past periods, and this could occur in future periods.

UScellular believes that existing cash and investment balances, funds available under its financing agreements, its ability to obtain future external financing, potential dispositions and expected cash flows from operating and investing activities will provide sufficient liquidity for UScellular to meet its day-to-day operating needs and debt service requirements. UScellular may require substantial additional funding for, among other uses, capital expenditures, acquisitions of providers of wireless telecommunications services, wireless spectrum license acquisitions, agreements to purchase goods or services, leases, repurchases of shares, or making additional investments. It may be necessary from time to time to increase the size of its existing credit facilities, to amend existing or put in place new credit agreements, to obtain other forms of financing, issue equity securities, or to divest assets in order to fund potential expenditures. UScellular will continue to monitor the rapidly changing business and market conditions and is taking and intends to take appropriate actions, as necessary, to meet its liquidity needs.

Cash and cash equivalents include cash and money market investments. The primary objective of UScellular's Cash and cash equivalents investment activities is to preserve principal.

In addition to Cash and cash equivalents, UScellular had available undrawn borrowing capacity (taking into account debt covenant restrictions) from the following debt facilities at December 31, 2023. See the Financing section below for further details.

UScellular has an unsecured revolving credit agreement with a maximum borrowing capacity of $300 million. Amounts under the revolving credit agreement may be borrowed, repaid and reborrowed from time to time until maturity in July 2026. As of December 31, 2023, there were no outstanding borrowings under the revolving credit agreement, and UScellular’s unused borrowing capacity was $300 million.

UScellular has term loan agreements with maximum borrowing capacities of $800 million. The maturity dates for the term loan agreements range from July 2026 to July 2031. As of December 31, 2023, UScellular has borrowed the full amount available under the agreements and the outstanding borrowings were $783 million.

UScellular has a $150 million term loan credit facility with Export Development Canada to finance (or refinance) imported equipment, including equipment purchased prior to entering the term loan facility agreement. The maturity date for the agreement is January 2027. As of December 31, 2023, UScellular has borrowed the full amount available under the agreement.

UScellular, through its subsidiaries, has a receivables securitization agreement that permits securitized borrowings using its equipment installment plan receivables. In September 2023, UScellular amended the agreement to extend the maturity date to September 2025. Amounts under the agreement may be borrowed, repaid and reborrowed from time to time until maturity. Unless the agreement is amended to extend the maturity date, repayments based on receivable collections commence in October 2025. During 2023, UScellular borrowed $315 million and repaid $440 million under the agreement. As of December 31, 2023, the outstanding borrowings under the agreement were $150 million and the unused borrowing capacity was $300 million, subject to sufficient collateral to satisfy the asset borrowing base provisions of the agreement. 

In January 2024, UScellular repaid $50 million under the agreement.

UScellular, through a subsidiary (the repo subsidiary), had a repurchase agreement to borrow up to $200 million, subject to the availability of eligible equipment installment plan receivables and the agreement of the lender. In January 2023, UScellular amended the repurchase agreement to extend the expiration date to January 2024. During 2023, the repo subsidiary repaid $60 million under the repurchase agreement. As of December 31, 2023, there were no outstanding borrowings under the repurchase agreement and the unused borrowing capacity was $200 million, which was restricted from being borrowed due to covenants within the TDS and UScellular credit agreements that limit secured borrowings on an enterprise-wide basis.

The repurchase agreement expired in January 2024.

The revolving credit agreement, term loan agreements, export credit financing agreement and receivables securitization agreement require UScellular to comply with certain affirmative and negative covenants, which include certain financial covenants that may restrict the borrowing capacity available. In March 2023, the agreements were amended to require UScellular to maintain the Consolidated Leverage Ratio as of the end of any fiscal quarter at a level not to exceed the following: 4.25 to 1.00 from January 1, 2023 through March 31, 2024; 4.00 to 1.00 from April 1, 2024 through March 31, 2025; 3.75 to 1.00 from April 1, 2025 and thereafter. UScellular is also required to maintain the Consolidated Interest Coverage Ratio at a level not lower than 3.00 to 1.00 as of the end of any fiscal quarter. UScellular believes that it was in compliance as of December 31, 2023 with all such financial covenants. 

UScellular believes that it was in compliance as of December 31, 2023, with all covenants and other requirements set forth in the UScellular long-term debt indentures. UScellular has not failed to make nor does it expect to fail to make any scheduled payment of principal or interest under such indentures.

UScellular has an effective shelf registration statement on Form S-3 to issue senior or subordinated debt securities, preferred shares and depositary shares. The proceeds from any such issuance may be used for general corporate purposes, including the possible reduction of other short-term or long-term debt; spectrum purchases; capital expenditures; acquisition, construction and development programs; working capital; additional investments in subsidiaries; or the repurchase of shares. The ability of UScellular to complete an offering pursuant to such shelf registration statement is subject to market conditions and other factors at the time.

UScellular, at its discretion, may from time to time seek to retire or purchase its outstanding debt through cash purchases and/or exchanges for other securities, in open market purchases, privately negotiated transactions, tender offers, exchange offers or otherwise. Such repurchases or exchanges, if any, will depend on prevailing market conditions, liquidity requirements, contractual restrictions and other factors. The amounts involved may be material.

Refer to Market Risk — Long-Term Debt for additional information regarding required principal payments and the weighted average interest rates related to UScellular’s Long-term debt.

See Note 12 — Debt in the Notes to Consolidated Financial Statements for additional information related to the financing agreements.

In certain circumstances, UScellular’s interest cost on its various agreements may be subject to increase if its current credit ratings from nationally recognized credit rating agencies are lowered, and may be subject to decrease if the ratings are raised. UScellular’s agreements do not cease to be available nor do the maturity dates accelerate solely as a result of a downgrade in credit rating. However, a downgrade in UScellular’s credit rating or TDS' credit rating could adversely affect UScellular's ability to renew the agreements, obtain consents, waivers, or amendments, or obtain access to other credit agreements in the future.

UScellular is rated as a sub-investment grade issuer. The UScellular issuer credit ratings as of December 31, 2023, and the dates such ratings were re-affirmed were as follows:

Following the announcement on August 4, 2023 related to the review of strategic alternatives for UScellular, Standard & Poor's placed the BB issuer credit rating for UScellular on CreditWatch with developing implications. Per the release, this action reflects the potential for a higher or lower rating depending on the outcome of the strategic alternatives review. Further, Standard & Poor's indicated they expect to resolve the CreditWatch placement once they have sufficient information following the conclusion of the strategic review process. At the same time, Moody's issued a release indicating that UScellular's Ba1 issuer credit rating is not immediately impacted given the uncertainty around potential outcomes. Fitch Ratings did not issue a public statement.

The discussion below is intended to highlight some of the significant cash outlays expected during 2024 and beyond and to highlight the spending incurred in current and prior years for these items. This discussion does not include cash required to fund normal operations, and is not a comprehensive list of capital requirements. Significant cash requirements that are not routine or in the normal course of business could arise from time to time.

UScellular makes substantial investments to acquire, construct and upgrade wireless telecommunications networks and facilities to remain competitive and as a basis for creating long-term value for shareholders. In recent years, rapid changes in technology and new opportunities (such as 5G and VoLTE technology) have required substantial investments in potentially revenue‑enhancing and cost-saving upgrades of UScellular’s networks to remain competitive; this is expected to continue in 2024 and future years with the continued deployment of 5G technology.

UScellular intends to finance its capital expenditures for 2024 using primarily Cash flows from operating activities, existing cash balances and, as required, additional debt financing from its existing agreements and/or other forms of available financing.

UScellular may be engaged in negotiations (subject to all applicable regulations) relating to the acquisition, divestiture or exchange of companies, properties, assets, or wireless spectrum licenses (including pursuant to FCC auctions). In general, UScellular may not disclose such transactions until there is a definitive agreement.

UScellular will require capital for future spending on existing contractual obligations, including long-term debt obligations; lease commitments; commitments for device purchases, network facilities and transport services; agreements for software licensing; long-term marketing programs; commitments for wireless spectrum licenses acquired through FCC auctions; and other agreements to purchase goods or services.

UScellular consolidates certain “variable interest entities” as defined under GAAP. See Note 14 — Variable Interest Entities in the Notes to Consolidated Financial Statements for additional information related to these variable interest entities. UScellular may elect to make additional capital contributions and/or advances to these variable interest entities in future periods to fund their operations.

Depending on its future financial performance, construction, development and acquisition programs, and available sources of financing, UScellular may not have sufficient liquidity or capital resources to make share repurchases. Therefore, there is no assurance that UScellular will make any share repurchases in the future.

For additional information related to the current repurchase authorization, see Note 16 — Common Shareholders’ Equity in the Notes to Consolidated Financial Statements.

UScellular operates a capital‑intensive business. UScellular makes substantial investments to acquire wireless spectrum licenses and properties and to construct and upgrade wireless telecommunications networks and facilities with a goal of creating long-term value for shareholders. In recent years, rapid changes in technology and new opportunities have required substantial investments in potentially revenue‑enhancing and cost-saving upgrades to UScellular’s networks. Revenues from certain of these investments are long-term and in some cases are uncertain. To meet its cash-flow needs, UScellular may need to delay or reduce certain investments or sell assets. Refer to Liquidity and Capital Resources within this MD&A for additional information. Cash flows may fluctuate from quarter to quarter and year to year due to seasonality, timing and other factors. The following discussion summarizes UScellular’s cash flow activities in 2023 and 2022.

UScellular’s Cash, cash equivalents and restricted cash decreased $129 million. Net cash provided by operating activities was $866 million due to net income of $58 million adjusted for non-cash items of $693 million and distributions received from unconsolidated entities of $150 million including $69 million in distributions from the LA Partnership. This was partially offset by changes in working capital items which decreased net cash by $35 million. The working capital changes were primarily driven by the timing of vendor payments, partially offset by reduced inventory balances.

Cash flows used for investing activities were $721 million, which included payments for property, plant and equipment of $608 million and payments for wireless spectrum licenses of $130 million.

Cash flows used for financing activities were $274 million, due primarily to repayments of $440 million on the receivables securitization agreement, a $60 million repayment on the EIP receivables repurchase agreement and cash paid for software license agreements of $66 million, partially offset by $315 million borrowed under the receivables securitization agreement.

UScellular’s Cash, cash equivalents and restricted cash increased $109 million. Net cash provided by operating activities was $832 million due to net income of $35 million adjusted for non-cash items of $761 million and distributions received from unconsolidated entities of $145 million including $59 million in distributions from the LA Partnership. This was partially offset by changes in working capital items which decreased net cash by $109 million. The working capital changes were primarily influenced by an increase in receivable and inventory balances, partially offset by a federal income tax refund of $123 million received during the first quarter of 2022. The increase in receivables was driven by a high volume of equipment upgrades due to promotional activities and a longer contract term for equipment installment plans.

Cash flows used for investing activities were $1,179 million, which included payments for property, plant and equipment of $602 million and payments for wireless spectrum licenses of $585 million. Cash payments for property, plant and equipment are lower than the total capital expenditures in 2022 due primarily to future obligations of certain software license agreements that are recorded as current year capital expenditures but are paid over time.

Cash flows provided by financing activities were $456 million, due primarily to $500 million borrowed under the term loan facilities, $150 million borrowed under the export credit financing agreement, $110 million borrowed under the EIP receivables repurchase agreement, $75 million borrowed under the revolving credit agreement, and $75 million borrowed under the receivables securitization agreement. These were partially offset by $250 million of repayments on the receivables securitization agreement, a $75 million repayment on the revolving credit agreement, a $50 million repayment on the EIP receivables repurchase agreement, the repurchase of $43 million of Common Shares and cash paid for software license agreements of $22 million.

Accounts receivable, other decreased $33 million due primarily to the collection of vendor credits from original equipment manufacturers.

Accounts payable, trade decreased $103 million due primarily to the timing of vendor invoice payments related to inventory.

Other current liabilities decreased $181 million due primarily to the payment of Auction 107 relocation fees and repayments on the EIP receivables repurchase agreement.

UScellular prepares its consolidated financial statements in accordance with GAAP. UScellular’s significant accounting policies are discussed in detail in Note 1 — Summary of Significant Accounting Policies, Note 2 — Revenue Recognition and Note 10 — Leases in the Notes to Consolidated Financial Statements.

Management believes the application of the following critical accounting policies and the estimates required by such application reflect its most significant judgments and estimates used in the preparation of UScellular’s consolidated financial statements.

Wireless spectrum licenses represent a significant component of UScellular’s consolidated assets. Wireless spectrum licenses are considered to be indefinite-lived assets, and therefore are not amortized but are tested at least annually for impairment. Significant negative events, such as changes in any of the assumptions described below as well as decreases in forecasted cash flows, could result in an impairment. Wireless spectrum licenses are tested for impairment at the level of reporting referred to as a unit of accounting.

For purposes of its impairment test, UScellular has one unit of accounting. UScellular performed a quantitative impairment assessment in 2023 and a qualitative impairment assessment in 2022.

In 2023, a market approach was used to value the wireless spectrum license portfolio. The wireless spectrum licenses were pooled by band, and a range of values was established using industry benchmarks, FCC auction data, and precedent transactions. The midpoint of the range was established as the point estimate for the value of each band, and the sum of the band values was used as the point estimate value of UScellular's wireless spectrum license unit of accounting. Based on this valuation, the fair value of the wireless spectrum licenses exceeded the respective carrying value by 17% and there was no impairment of wireless spectrum licenses.

In 2022, UScellular considered several qualitative factors, including analyst estimates of wireless spectrum license values, recent spectrum auction results, UScellular and other market participant transactions, and other industry and market factors. Based on these assessments, UScellular concluded that it was more likely than not that the fair value of the unit of accounting exceeded its carrying value. Therefore, no quantitative impairment evaluation was completed.

See Note 7 — Intangible Assets in the Notes to Consolidated Financial Statements for information related to wireless spectrum licenses activity in 2023 and 2022.

UScellular is included in a consolidated federal income tax return with other members of the TDS consolidated group. TDS and UScellular are parties to a Tax Allocation Agreement which provides that UScellular and its subsidiaries be included with the TDS affiliated group in a consolidated federal income tax return and in state income or franchise tax returns in certain situations. For financial statement purposes, UScellular and its subsidiaries calculate their income, income tax and credits as if they comprised a separate affiliated group. Under the Tax Allocation Agreement between TDS and UScellular, UScellular remits its applicable income tax payments to TDS, and receives applicable tax refunds from TDS, consistent with when such payments would be paid or received if UScellular and its subsidiaries were a separate affiliated group.

The amounts of income tax assets and liabilities, the related income tax provision and the amount of unrecognized tax benefits are critical accounting estimates because such amounts are significant to UScellular’s financial condition and results of operations.

The preparation of the consolidated financial statements requires UScellular to calculate a provision for income taxes. This process involves estimating the actual current income tax liability together with assessing temporary differences resulting from the different treatment of items for tax purposes. These temporary differences result in deferred income tax assets and liabilities which are included on a net basis in UScellular’s Consolidated Balance Sheet. UScellular must then assess the likelihood that deferred income tax assets will be realized based on future taxable income and, to the extent management believes that realization is not likely, establish a valuation allowance. Management’s judgment is required in determining the provision for income taxes, deferred income tax assets and liabilities and any valuation allowance that is established for deferred income tax assets.

UScellular recognizes the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are measured based on management’s judgment as to the possible outcome that has a greater than 50% cumulative likelihood of being realized upon ultimate resolution. 

On October 27, 2020, the FCC adopted rules creating the 5G Fund for Rural America, which will distribute up to $9 billion over ten years to bring 5G wireless broadband connectivity to rural America. The 5G Fund will be implemented through a two-phase competitive process, using multiround auctions to award support. The winning bidders will be required to meet certain minimum speed requirements and interim and final deployment milestones. The order provides that the 5G Fund be in lieu of the previously proposed fund (the Phase II Connect America Mobility Fund) for the development of 4G LTE. The order also provides that over time a growing percentage of the legacy support a carrier receives must be used for 5G deployment. On September 22, 2023, the FCC adopted a Further Notice of Proposed Rulemaking (FNPRM) to continue implementation of the 5G Fund. The FCC sought comment on, among other things, the definition of areas eligible for 5G Fund support, adjustment factors and metrics used to identify winning bids, and the potential inclusion of cybersecurity and supply chain management requirements for those receiving 5G Fund support.

UScellular cannot predict at this time when the 5G Fund auction will occur, when the phase down period for its existing legacy support from the Federal USF will commence, or whether the 5G Fund auction will provide opportunities to UScellular to offset any loss in existing support.

On March 2, 2020, the FCC released a Public Notice establishing procedures for an auction offering wireless spectrum licenses in the 3.5 GHz band (Auction 105). On September 2, 2020, the FCC announced by way of public notice that UScellular was the provisional winning bidder for 243 wireless spectrum licenses for a purchase price of $14 million. On July 15, 2022, the FCC released a Consent Decree related to its spectrum aggregation and ownership attribution rules in which UScellular agreed to relinquish its rights to 27 wireless spectrum licenses awarded in Auction 105 and subsequently received a full refund of $2 million. The remaining 216 wireless spectrum licenses were granted by the FCC on July 26, 2022.

On August 7, 2020, the FCC released a Public Notice establishing procedures for an auction offering wireless spectrum licenses in the 3.7-3.98 GHz bands (Auction 107). On February 24, 2021, the FCC announced by way of public notice that UScellular was the provisional winning bidder for 254 wireless spectrum licenses for $1,283 million. UScellular paid $30 million of this amount in 2020 and the remainder in March 2021. The wireless spectrum licenses from Auction 107 were granted by the FCC in July 2021. Additionally, UScellular was obligated to pay approximately $179 million in total from 2021 through 2025 related to relocation costs and accelerated relocation incentive payments. Such additional costs were accrued and capitalized at the time the licenses were granted, and are adjusted as necessary as the estimated obligation changes. UScellular paid $122 million, $8 million and $36 million related to the additional costs for the years ended December 31, 2023, 2022 and 2021, respectively. UScellular received full access to the spectrum in the third quarter of 2023.

On June 9, 2021, the FCC released a Public Notice establishing procedures for an auction offering wireless spectrum licenses in the 3.45-3.55 GHz band (Auction 110). On January 14, 2022, the FCC announced by way of public notice that UScellular was the provisional winning bidder for 380 wireless spectrum licenses for $580 million. UScellular paid $20 million of this amount in 2021 and the remainder in the first quarter of 2022. The wireless spectrum licenses from Auction 110 were granted by the FCC on May 4, 2022.

On March 21, 2022, the FCC released a Public Notice establishing procedures for an auction offering wireless spectrum licenses in the 2.5 GHz band (Auction 108). On September 1, 2022, the FCC announced by way of public notice that UScellular was the provisional winning bidder for 34 wireless spectrum licenses for $3 million. The wireless spectrum licenses from Auction 108 were granted by the FCC on December 1, 2022.

As of December 31, 2023, approximately 70% of UScellular's long-term debt was in fixed-rate senior notes and approximately 30% in variable-rate debt. Fluctuations in market interest rates can lead to volatility in the fair value of fixed-rate notes and interest expense on variable-rate debt.

At December 31, 2023 and 2022, the estimated fair value of long-term debt obligations, excluding lease obligations, the current portion of such long-term debt and debt financing costs, was $2,611 million and $2,502 million, respectively, and the book value was $3,099 million and $3,244 million, respectively. See Note 3 — Fair Value Measurements in the Notes to Consolidated Financial Statements for additional information.

UScellular sometimes uses information derived from consolidated financial information but not presented in its financial statements prepared in accordance with GAAP to evaluate the performance of its business. Certain of these measures are considered “non-GAAP financial measures” under U.S. Securities and Exchange Commission Rules. Specifically, UScellular has referred to the following measures in this Form 10-K Report:

Following are explanations of each of these measures:

EBITDA, Adjusted EBITDA and Adjusted OIBDA are defined as Net income adjusted for the items set forth in the reconciliation below. EBITDA, Adjusted EBITDA and Adjusted OIBDA are not measures of financial performance under 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. UScellular does not intend to imply that any such items set forth in the reconciliation below are non-recurring, infrequent or unusual; such items may occur in the future.
