PART I.

Item 1. Business

Business Overview and Strategy

Un-carrier Strategy

As America’s supercharged Un-carrier, we have disrupted the wireless communications services industry by actively engaging with and listening to our customers and focusing on eliminating their pain points. Our customers benefit from what we believe is an unmatched combination of value and network quality, unwavering focus on offering them the best possible service experience and undisputable drive for disruptive innovation in wireless and beyond. This includes providing added value and what we believe is an exceptional experience while implementing signature Un-carrier initiatives that have changed the wireless industry. We ended annual service contracts, overages, unpredictable international roaming fees and data buckets, among other things. We are inspired by a relentless focus on customer experience, consistently delivering award-winning customer experience, which drives our customer satisfaction levels while enabling operational efficiencies.

With what we believe is America’s largest, fastest, most awarded and most advanced 5G network, the Un-carrier strives to offer customers unrivaled coverage and capacity where they live, work and travel. We believe our network is the foundation of our success and powers everything we do. Our dense and multi-layer network provides an unmatched 5G and overall network experience to our customers, which consists of our foundational layer of low-band, our mid-band and our millimeter-wave (“mmWave”) spectrum licenses (see “Spectrum Position” below). This multilayer portfolio of spectrum broadens and deepens our nationwide 5G network, enabling accelerated innovation and increased competition in the U.S. wireless and broadband industries.

We continue to expand the footprint and improve the quality of our network, enabling us to provide what we believe are outstanding wireless experiences for customers who should not have to compromise on quality and value. Our network allows us to deliver new, innovative products and services, such as our High Speed Internet fixed wireless product, with the same customer experience focus and industry-disrupting mindset that we have adopted in our attempt to redefine the wireless communications services industry in the United States in the customers’ favor.

As part of our relentless, customer-first focus, we are transforming into an AI-enabled, data-informed, digital-first organization to continue delivering differentiated experiences to our customers. Leveraging the latest AI technology and digital capabilities, we are pioneering new approaches to serving customers with a platform to better anticipate and proactively solve their issues, offering personalized self-service options and taking authorized actions on their behalf, while simultaneously creating large-format customer experience stores for customers looking for an immersive experience, and increasing investment in domestic customer care. Our comprehensive T-Life app will further allow us to tap into customer preferences and radically simplify customer experiences in the future.

Our Operations

As of December 31, 2024, we provide wireless communications services to 129.5 million postpaid and prepaid customers and generate revenue by providing affordable wireless communications services to these customers, as well as a wide selection of wireless devices and accessories. We also provide wholesale wireless services to various partners, who then offer the services for sale to their customers. Our most significant expenses relate to operating and expanding our network, providing a full range of devices, acquiring and retaining high-quality customers and compensating employees. We provide services, devices and accessories across our flagship brands, T-Mobile, Metro by T-Mobile and Mint Mobile, through our T-Mobile and Metro by T-Mobile owned and operated retail stores, as well as through our websites (www.t-mobile.com, www.metrobyt-mobile.com and www.mintmobile.com), T-Mobile, Metro by T-Mobile and Mint Mobile apps, customer care channels and through national retailers. In addition, we sell devices to dealers and other third-party distributors for resale through independent third-party retail outlets and a variety of third-party websites. The information on our websites is not part of this Form 10-K. See Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations for additional information.

Services and Products

We provide wireless communications services through a variety of service plan options. We also offer for sale to customers a wide selection of wireless devices, including smartphones, wearables, tablets, home broadband routers and other mobile communication devices that are manufactured by various suppliers.

Our most popular service plan offering is Go5G Plus, which includes unlimited talk, text and data on our network, 5G access at no extra cost, scam protection features, access to the same device offers as new customers and more. We also offer an Essentials rate plan for customers who want the basics at a lower price point, specific rate plans to qualifying customers, including Military and Veterans, First Responder and 55+, as well as Go5G and Go5G Next plans to deliver a full suite of plans that provide customers the features that meet their lifestyle and daily needs.

At the time of device purchase, qualified customers can finance all or a portion of the individual device or accessory purchase price over an installment period, generally of 24 months, using an equipment installment plan (“EIP”).

In addition to our wireless communications services, we offer High Speed Internet, which includes a fixed wireless product that utilizes the excess capacity of our nationwide 5G network. Our fixed wireless product is available to tens of millions of domestic households where we currently have excess network capacity, providing, for some consumers, an alternative to traditional landline internet or broadband service providers and expanding access to and choice for some consumers. With our High Speed Internet plan, customers can access the internet without worrying about annual service contracts, data overages or hidden fees.

We also provide products and services that are complementary to our wireless communications services, including device protection, financial services and advertising.

Customers

We provide wireless communications services to a variety of customers needing connectivity, but focus primarily on two categories of customers:

Postpaid customers generally are qualified to pay after receiving wireless communications services utilizing phones, High Speed Internet modems, mobile internet devices (including tablets and hotspots), wearables, DIGITS and other connected devices (including SyncUP and internet of things (“IoT”)). We serve consumers as well as business customers, who are provided services under the T-Mobile for Business brand.
Prepaid customers generally pay for wireless communications services in advance. We serve prepaid customers under the T-Mobile, Metro by T-Mobile, Mint Mobile and Ultra Mobile brands.

We provide Machine-to-Machine (“M2M”) and Mobile Virtual Network Operator (“MVNO”) customers access to our network. This access and the customer relationship are managed by wholesale partners, with whom we have commercial agreements permitting them to sell services utilizing our network.

We generate the majority of our service revenues by providing wireless communications services to postpaid and prepaid customers. Our ability to attract and retain postpaid and prepaid customers is important to our business in the generation of service revenues, equipment revenues and other revenues. In 2024, our service revenues generated by providing wireless communications services by customer category were:

79% Postpaid customers;
16% Prepaid customers; and
5% Wholesale and other services.

Substantially all of our revenues for the years ended December 31, 2024, 2023 and 2022, were earned in the United States, including Puerto Rico and the U.S. Virgin Islands.

Network Strategy

Utilizing our multilayer spectrum portfolio, our mission is to become “Famous for Network.” We have deployed low-band, mid-band and mmWave spectrum dedicated for 5G across our dense and broad network to create what we believe is America’s largest, fastest, most awarded and most advanced 5G network.

We believe our spectrum position and focus on technology leadership will continue to drive network differentiation. Our innovative Customer-Driven Coverage (“CDC”) approach to network investments, and leadership in deploying the latest network technologies including Massive Multiple-input/multiple-out (“Massive MIMO”), Voice over New Radio (“VoNR”), four-carrier and higher order aggregation, dynamic network slicing and the U.S.’s first broad deployment of 5G Advanced, are

enabled by our scaled nationwide 5G standalone network. We are also part of an alliance working to bring Radio Access Network (“RAN”) and AI innovation closer together to deliver transformational network experiences in the future.

Spectrum Position

We provide wireless communications services utilizing low-band spectrum licenses covering our 600 MHz and 700 MHz spectrum, mid-band spectrum licenses, such as Advanced Wireless Services (“AWS”), Personal Communications Services (“PCS”) and 2.5 GHz spectrum, and mmWave spectrum.

We controlled an average of 394 MHz of combined low- and mid-band spectrum nationwide as of December 31, 2024. This spectrum is comprised of:
An average of 41 MHz in the 600 MHz band;
An average of 10 MHz in the 700 MHz band;
An average of 14 MHz in the 800 MHz band;
An average of 41 MHz in the 1700 MHz AWS band;
An average of 66 MHz in the 1900 MHz PCS band;
An average of 184 MHz in the 2.5 GHz band;
An average of 11 MHz in the 3.45 GHz band; and
An average of 27 MHz in the C-band.
We controlled an average of 1,033 GHz of combined mmWave spectrum licenses.
In September 2023, we entered into a License Purchase Agreement with Comcast Corporation and its affiliate, Comcast OTR1, LLC (together with Comcast Corporation, “Comcast”) pursuant to which we will acquire spectrum in the 600 MHz band in exchange for total cash consideration of between $1.2 billion and $3.3 billion. On January 13, 2025, we and Comcast entered into an amendment to the License Purchase Agreement pursuant to which we will acquire additional spectrum. Subsequent to the amendment, the total cash consideration for the transaction is between $1.2 billion and $3.4 billion. See Note 7 – Goodwill, Spectrum License Transactions and Other Intangible Assets of the Notes to the Consolidated Financial Statements for additional details.
We plan to evaluate future spectrum purchases in future auctions and secondary market opportunities to further augment or refine our current spectrum position.
As of December 31, 2024, we had equipment deployed on approximately 82,000 macro cell sites and 52,000 small cell/distributed antenna system sites across our network.

Competition

The wireless communications services industry remains competitive. We are the second largest provider of wireless communications services in the U.S. as measured by our total postpaid and prepaid customers. Our wireless communications services competitors include other carriers, such as AT&T Inc. (“AT&T”), Verizon Communications, Inc. (“Verizon”), and DISH Network Corporation (“DISH”) as it continues to grow its network. In addition, our competitors include numerous smaller and regional providers, including Comcast Corporation, Charter Communications, Inc., Cox Communications, Inc., and Altice USA, Inc., many of which offer no-contract, postpaid and prepaid service plans. Competitors also include providers who offer similar communication services, such as voice, messaging and data services, using alternative technologies. In addition to our wireless communications services, our High Speed Internet service competes against other broadband providers, including traditional wireline solutions, such as Cable, DSL and Fiber broadband providers, and fixed wireless solutions, including AT&T and Verizon’s fixed wireless products, and Satellite Internet providers. Competitive factors within the wireless communications services and broadband industries include pricing, market saturation, service and product offerings, customer experience, network investment and quality, development and deployment of technologies and regulatory changes. Some of our competitors have shown a willingness to use discounted pricing or offer bundled services as a potential source of differentiation. 

Human Capital

Employees

As of December 31, 2024, we employed approximately 70,000 full-time and part-time employees, including network, retail, administrative and customer support functions.

We put employees in the driver’s seat and give them access to mentoring, training, videos, books, job search and interview tips, and much more.

By strategically investing in the following three key areas of career development and learning, we are developing our talent now and for the future.

Evolve skills and careers – Learn every day, champion relentless improvement, develop critical skills, explore career possibilities, and build the desired career;
Advance leadership expertise – Build critical leadership capabilities, enable leadership growth at all levels, and develop skills to lead in the future; and
Champion belonging and inclusion – Promote inclusive habits and behaviors and enhance belonging and connectedness.

Belonging and Inclusion

Our diversity, equity and inclusion efforts are focused on fostering a workplace that helps us better serve our customers and communities across the nation. We aim to create an environment where employees feel included, valued and empowered, contributing to a stronger, more connected business. T-Mobile has an inclusive hiring process that seeks diverse talent to be candidates for employment, but all of our hiring decisions continue to be based solely on merit.

Employee Resource Groups (ERGs)

Many of our employees participate in one of six Employee Resource Groups (ERGs) and their sub-groups, which are instrumental in promoting connection. Each of these groups is open to any and all employees, and there are 38 chapters nationwide that organize volunteer opportunities and local events.

Women & Allies Network.

These groups offer immersive experiences, mentorship programs, networking opportunities, and community service projects. They are designed to help participants grow as professionals and community leaders.

External Diversity Councils

In partnership with civil rights organizations, we had previously established two External Diversity and Inclusion Councils. These councils offered guidance for our efforts in areas like workforce recruitment, procurement, community investment, and corporate governance. The work with these external councils concluded as planned after a successful 5-year collaboration and the councils have been dissolved.

Suppliers

T-Mobile considers a broad range of suppliers, including those that are veteran-owned, disability-owned, woman-owned, minority-owned, and LGBT-owned, and we include small and large businesses of all kinds in our procurement processes. Purchases and contracts are awarded based on the best qualified and most competitive suppliers to enable T-Mobile’s success.

Environmental Sustainability

Efficiencies and Reducing Our Carbon Footprint

We are actively working to identify efficiencies in our energy usage and reduce our environmental impact by:

Pursuing a science-based net-zero emissions target for 2040, covering Scope 1, 2, and 3 emissions;
Investing in renewable energy, meeting our RE100 pledge since 2021, through initiatives such as Virtual Power Purchasing Agreements and clean energy projects producing over 3.4 million megawatt hours annually;
Enhancing energy efficiency in our facilities, including retail stores, data centers, and cell sites; and
Promoting a circular economy through a robust device reuse and recycling program.

Responsible Sourcing

We believe our suppliers are a valuable extension of our business and corporate values. Our Supplier Code of Conduct outlines expectations around ethical business practices for our suppliers. We require our suppliers to operate in compliance with the laws, rules, regulations and ethical standards of the countries in which they operate or provide products or services. We expect our suppliers to share our commitment to ethical conduct and environmentally responsible business practices while they conduct business with or on behalf of us. Our Responsible Sourcing Policy further outlines T-Mobile’s expectations in this area.

We employ a third-party risk management (“TPRM”) process to screen for anti-corruption, global sanctions, human rights and environmental risks before engaging with a supplier. Our TPRM process also continuously monitors current suppliers for policy violations and risks.

Regulation

The FCC regulates many key aspects of our business, including licensing, construction, the operation and use of our network, modifications of our network, control and ownership of our licenses and authorizations, the sale, transfer and acquisition of certain licenses, domestic roaming arrangements and interconnection agreements, pursuant to its authority under the Communications Act of 1934, as amended (“Communications Act”). The FCC has a number of complex requirements that affect our operations and pending proceedings regarding additional or modified requirements that could increase our costs or diminish our revenues. For example, the FCC has rules regarding provision of 911, 988 and E-911 services, porting telephone numbers, interconnection, roaming, internet openness or net neutrality, robocalling/robotexting, disabilities access, privacy and cybersecurity, digital discrimination, consumer protection and the universal service and Lifeline programs. Many of these and other issues are being considered in ongoing proceedings, and we cannot predict whether or how such actions will affect our business, financial condition or operating results. Our ability to provide services and generate revenues could be harmed by adverse regulatory action or changes to existing laws and regulations. In addition, regulation of companies that offer competing services can impact our business indirectly.

Except for operations in certain unlicensed frequency bands, wireless communications services providers generally must be licensed by the FCC to provide communications services at specified spectrum frequencies within specified geographic areas and must comply with the rules and policies governing the use of the spectrum as adopted by the FCC. The FCC issues each license for a fixed period of time, typically 10-15 years depending on the particular licenses. While the FCC has generally renewed licenses given to operating companies like us, the FCC has authority both to revoke a license for cause and to deny a license renewal if a renewal is not in the public interest. Furthermore, we could be subject to fines, forfeitures and other penalties for failure to comply with FCC regulations, even if any such noncompliance was unintentional. In extreme cases, penalties can include revocation of our licenses. The loss of any licenses, or any related fines or forfeitures, could adversely affect our business, results of operations and financial condition. In addition, the FCC retains the right to modify rules related to use of licensed spectrum, which could impact T-Mobile’s ability to provide services.

Additionally, Congress’s and the FCC’s allocation of additional spectrum for broadband commercial mobile radio service (“CMRS”), which includes cellular, PCS and other wireless services, could significantly increase and intensify competition. We cannot assess the impact that any developments that may occur in the U.S. economy or any future spectrum allocations by the FCC may have on license values. FCC spectrum auctions and other market developments may adversely affect the market value of our licenses or our competitive position in the future. A significant decline in the value of our licenses could adversely affect our financial condition and results of operations. In addition, the FCC periodically reviews its policies on how to evaluate carriers’ spectrum holdings in the context of spectrum transactions or acquisitions. Most recently, for example, in September 2023, the FCC sought public comment on whether it should initiate a rulemaking proceeding to consider changes to its mobile spectrum rules and policies. A change in these rules and policies could affect our access to additional spectrum resources and competition among us and other carriers.

Congress and the FCC have imposed limitations on foreign ownership of CMRS licensees. Direct foreign ownership in the licensee of more than 20% is prohibited. Indirect foreign ownership of more than 25% through an entity controlling the licensee must be reviewed and approved by the FCC as not inconsistent with the public interest. Consistent with that established policy, the FCC has issued a declaratory ruling authorizing up to 100% ownership of our Company by DT.

For our Educational Broadband Service (“EBS”) licenses in the 2.5 GHz band, FCC rules previously limited eligibility to hold EBS licenses to accredited educational institutions and certain governmental, religious and nonprofit entities, while permitting those license holders to lease their licenses to commercial providers for non-educational purposes. Therefore, we have historically accessed EBS spectrum primarily through long-term leasing arrangements with EBS license holders. Our EBS spectrum leases typically have an initial term equal to the remaining term of the EBS license, with an option to renew the lease for additional terms, for a total lease term of up to 30 years. In April 2020, the FCC lifted the restriction on who can hold EBS licenses and the 30-year limitation on lease duration, among other changes. The elimination of these restrictions allows current license holders to sell their licenses, including to T-Mobile. While a majority of our leases have contractual provisions enabling us to match offers, we may be forced to compete with others to purchase 2.5 GHz licenses on the secondary market and expend additional capital earlier than we may have anticipated. T-Mobile has started to acquire some of these EBS licenses, but we continue to lease spectrum in this band and expect that to be the case for some time.

While the Communications Act generally preempts state and local governments from regulating the entry of, or the rates charged by, wireless communications services providers, certain state and local governments regulate other terms and conditions of wireless service, including billing, termination of service arrangements and the imposition of early termination fees, advertising, network outages, the use of devices while driving, service mapping, protection of consumer information, zoning and land use. Notwithstanding this federal preemption, several states are considering or have passed laws or regulations
11

Table of Contents
that could potentially set prices, minimum performance standards and/or restrictions on service discontinuation that could impact our business in those states.

For example, following the FCC’s adoption of the 2017 Restoring Internet Freedom (“RIF”) Order reclassifying broadband internet access services as non-common carrier “information services,” a number of states sought to impose state-specific net neutrality, rate-setting, and privacy requirements on providers’ broadband services. The FCC’s RIF Order expressly preempted such state efforts, which were inconsistent with the FCC’s federal deregulatory approach at that time. In 2019, however, the DC Circuit issued a ruling largely upholding the RIF Order but also vacating the portion of the ruling broadly preempting state/local measures regulating broadband services. The court left open the prospect that particular state laws could still unlawfully conflict with the FCC’s RIF Order and be preempted. In the meantime, the FCC sought to repeal the RIF Order through its adoption of the 2024 Open Internet Order, though the latter was struck down by a federal court of appeals in January 2025.

While most states pursuing net neutrality legislation sought to codify the federal rules repealed by the RIF Order, there are differences in some states. For example, California has passed separate privacy and net neutrality legislation, while many others have passed privacy laws, and New York has passed a broadband rate-setting law. There are also efforts within Congress to pass federal legislation to codify uniform federal privacy and net neutrality requirements. Ensuring the preemption of separate state requirements, including the California laws, is critical to this effort. If not preempted or rescinded, separate state requirements will impose significant business costs and could also result in increased litigation costs and enforcement risks. A number of states also subject wireless service providers to registration requirements. State authority over wireless broadband services will likely remain unsettled unless resolved by the courts, the FCC or Congress.

In addition, the Federal Trade Commission (“FTC”) and other federal agencies have jurisdiction over some consumer protection matters and the elimination and prevention of anticompetitive business practices with respect to the provision of non-common carrier services. Further, the FCC and the Federal Aviation Administration regulate the siting, lighting and construction of transmitter towers and antennae. Tower siting and construction are also subject to state and local zoning, as well as federal statutes regarding environmental and historic preservation. The future costs to comply with all relevant regulations are, to some extent, unknown, and changes to regulations, or the applicability of regulations, could result in higher operating and capital expenses, or reduced revenues in the future.

Item 1A. Risk Factors

In addition to the other information contained in this Form 10-K, the following risk factors should be considered carefully in evaluating T-Mobile. Our business, financial condition, liquidity, or operating results, as well as the price of our common stock and other securities, could be materially and adversely affected by any of these risks.

Risks Related to Our Business

We operate in a highly competitive industry. If we are unable to attract and retain customers, our business, financial condition, and operating results would be negatively affected.

The wireless communications services industry is highly competitive. As the industry reaches saturation, competition in all market segments, including prepaid, postpaid, enterprise and government customers will likely further intensify, putting pressure on pricing and/or margins for us and all our competitors. Our ability to attract and retain customers will depend on multiple factors, such as network quality and capacity, customer service excellence, effective marketing strategies, competitive pricing, compelling value propositions, and distribution and logistics capabilities. Additionally, targeted marketing approaches for diverse customer segments, coupled with continuous innovation in products and services, are essential for retaining and

Table of Contents
expanding our customer base. If we are unable to successfully differentiate our services from our competitors, it would adversely affect our competitive position and ability to grow our business.

We have seen and expect to continue to see intense competition in all market segments from traditional Mobile Network Operators (“MNOs”), such as AT&T and Verizon, who have each invested heavily in spectrum, their wireless networks, and services and device promotions, and DISH, as it continues to build out its wireless network and roll out services. Numerous other regional MNOs and MVNOs offering wireless services may also compete with us in some markets, including cable providers, such as Comcast, Charter, Cox, and Altice, as they continue to diversify their offerings to include wireless services offered under MVNO agreements. As new products and services emerge, we may also be forced to compete against non-traditional competitors from outside of the wireless communications services industry, such as satellite providers, offering similar connectivity services using alternative technologies.

In the market for broadband services, traditional cable providers, AT&T, Verizon, and other players such as satellite and fiber providers, all compete for customers. To complement our fixed wireless service, we have agreed to enter into joint venture agreements aimed at establishing a robust fiber wireline network in certain geographic regions that we believe will complement our fixed wireless services in those areas. However, these partnerships also involve inherent risks. See “Any acquisition, divestiture, investment, joint venture or merger may subject us to significant risks, any of which may harm our business” for further discussions of such risks.

If we are unable to compete effectively in attracting and retaining customers in markets where we operate, it could negatively impact our business, financial condition, and operating results.

We have experienced criminal cyberattacks and may experience disruption, data loss and other security breaches, whether directly or indirectly through third parties whose products and services we rely on in operating our business.

Our business involves the receipt, storage, and transmission of confidential information about our customers, such as sensitive personal, account and payment information, confidential information about our employees and suppliers, and other sensitive information about our Company, such as our business plans, transactions, financial information, and intellectual property (collectively, “Confidential Information”). Additionally, to offer services to our customers and operate our business, we utilize several applications and systems, including those we own and operate, such as our wireless network, as well as others provided to us by third parties, such as cloud service providers and SaaS companies (collectively, “Systems”).

We are subject to persistent cyberattacks and threats to our business from bad actors seeking to gain unauthorized access to Confidential Information and compromise Systems to undermine availability or integrity. They are perpetrated by a variety of groups and persons, including nation state-sponsored parties, malicious actors, employees, contractors, or other unrelated third parties. Some actors reside in jurisdictions where law enforcement measures to address such attacks are ineffective or unavailable.

Cyberattacks against companies like ours are increasing in frequency and scope of potential harm over time, and the methods used to gain unauthorized access constantly evolve, making it increasingly difficult to anticipate, prevent, and detect incidents successfully in every instance. In some cases, these bad actors exploit bugs, errors, misconfigurations or other vulnerabilities in our Systems to obtain Confidential Information. In other cases, these bad actors obtain unauthorized access to Confidential Information by exploiting insider access or utilizing log in credentials taken from our customers, employees, or third-party providers through credential harvesting, social engineering or other means. Other bad actors aim to cause serious operational disruptions to our business and Systems through ransomware or distributed denial of services attacks.

Although we regularly work to identify, track and remedy any security vulnerabilities, given the complex nature of our Systems and the tools that are available to us, we may be unable to identify vulnerabilities in a timely manner, or to apply patches or compensating measures that address such vulnerabilities, before bad actors can exploit them. The exploitation of a security vulnerability before patches or measures are applied could materially compromise Confidential Information and Systems.

In addition, we routinely rely upon third-party providers whose products and services are used in our business. These third-party providers have experienced, and will continue to experience cyberattacks that involve attempts to expose our Confidential Information and/or to create operational risk that could materially and adversely affect our business, and these providers also face other security challenges common to all parties that collect and process information. Additionally, our Systems include components from third parties or fourth parties we do not control and may have compromises, defects, flaws, or design errors unknown to us.

Table of Contents
As a result of the previously disclosed cyberattacks in August 2021 and January 2023, we incurred significant costs in connection with, among other things, responding to and resolving mass arbitration claims, multiple class action lawsuits and an FCC investigation. For more information on the foregoing, see “– Contingencies and Litigation – Litigation and Regulatory Matters” in Note 18 – Commitments and Contingencies of the Notes to the Consolidated Financial Statements.

In addition to the August 2021 cyberattack and the January 2023 cyberattack, we have experienced unrelated non-material incidents involving unauthorized access to certain Confidential Information and Systems. Typically, these incidents have involved attempts to commit fraud by taking control of a customer’s phone line, often by exploiting insider access or using compromised credentials. In other cases, the incidents have involved unauthorized access to certain of our customers’ private information, including payment information, financial data, social security numbers or passwords, and our intellectual property. Some of these incidents have occurred at third-party providers, including third parties who provide us with various Systems and others who sell our products and services through retail locations or take care of our customers.

In November 2024, it was publicly reported that a nation-state actor called “Salt Typhoon” successfully infiltrated the telecommunications networks of certain of our competitors to obtain information on their customers. While we have no evidence that any of our Systems or Confidential Information were impacted in any significant way, we may face similar attempts in the future.

Our procedures and safeguards to prevent unauthorized access to Confidential Information and to defend against cyberattacks seeking to disrupt our operations must be continually evaluated and enhanced to address the ever-evolving threat landscape and changing cybersecurity regulations, including while we adapt complex digital transformation efforts. These preventative actions require the investment of significant resources and management time and attention. Additionally, we do not have control of the cybersecurity systems, breach prevention, and response protocols of our third-party providers, including through our cybersecurity programs or policies. While T-Mobile may have contractual rights to assess the effectiveness of many of our providers’ systems and protocols, we do not have the means to always know or assess the effectiveness of all of our providers’ systems and controls. We cannot provide any assurances that actions taken by us, or our third-party providers, including through our cybersecurity programs or policies, will adequately repel a significant cyberattack or prevent or substantially mitigate the impacts of cybersecurity breaches or misuses of Confidential Information, unauthorized access to our networks or Systems or exploits against third-party environments, or that we, or our third-party providers, will be able to effectively identify, investigate, and remediate such incidents in a timely manner or at all. We expect to continue to be the target of cyberattacks, given the nature of our business, and we expect the same with respect to our third-party providers. We also expect that threat actors will continue to gain sophistication including in the use of tools and techniques (such as AI) that are specifically designed to circumvent security controls, evade detection, and obfuscate forensic evidence, making it more challenging for us to identify, investigate and recover from future cyberattacks in a timely and effective manner. In addition, we have acquired and continue to acquire companies with cybersecurity vulnerabilities or unsophisticated security measures, which exposes us to significant cybersecurity, operational, and financial risks. If we fail to protect Confidential Information or to prevent operational disruptions from future cyberattacks, there may be a material adverse effect on our business, reputation, financial condition, cash flows, and operating results.

If we fail to timely adopt and effectively deploy emerging network technologies, our competitive position could erode, which may adversely affect our business, financial condition, and operating results.

Our competitive advantage and reputation depend on our ability to provide industry-leading network coverage, speed, and reliability. While we have established a leadership position in 5G, the communications industry evolves rapidly, and emerging technologies – such as AI-driven Radio Access Networks (“AI-RAN”) and the potential transition to 6G – may redefine network standards and increase customer expectations. To stay ahead, we are investing in strategic collaborations with third parties, such as AI-RAN partnerships, to develop technologies that are intended to advance our network capabilities. Despite these efforts, we may encounter technical challenges, regulatory hurdles, supply chain constraints, or unexpected delays in developing and deploying new network technologies. If we fail to anticipate market trends, efficiently integrate innovative solutions into our network, or maintain the quality and reliability of our network, our market share and competitive standing could erode, adversely impacting our business and operating results.

If we fail to effectively execute our digital transformation and drive customer and employee adoption of emerging technologies, our competitive position and financial performance could be materially harmed.

We are engaged in complex digital transformation efforts intended to streamline operations, enhance customer experience, and improve our overall competitiveness. These initiatives involve integrating emerging and rapidly evolving technologies, reconfiguring internal processes, and implementing advanced data analytics and AI-driven tools, including those developed through our partnerships with a number of third-party providers. The successful execution of our planned transformation is
14

Table of Contents
subject to significant uncertainties. For example, we may face challenges in harmonizing complex system architectures, integrating new platforms with legacy infrastructure, and managing large volumes of data from disparate sources. We must also maintain rigorous data security and privacy safeguards, ensure our AI-driven solutions comply with evolving regulatory standards, and mitigate potential issues such as algorithmic bias or unintended operational disruptions. Additionally, implementing these digital solutions often requires substantial capital and operational expenditures, extensive employee training, specialized skill sets that may be difficult to source, and close coordination with multiple third-party vendors and partners. If we fail to execute these initiatives effectively, our ability to realize the intended benefits of digital transformation may be compromised. Even if we successfully deploy these capabilities, customer adoption and employee acceptance may be slower than anticipated, diminishing the expected improvements to efficiency, service quality, or revenue generation. This could materially and adversely affect our competitive position, financial performance, and brand reputation.

We rely on highly skilled personnel throughout all levels of our business. Our business could be harmed if we are unable to retain or motivate key personnel, hire a sufficient number of qualified new personnel, or maintain our corporate culture.

Our future success depends in substantial part on our ability to attract, recruit, hire, motivate, develop, and retain talented personnel possessing the qualifications, experiences, capabilities and skills we need for all areas of our organization, including our CEO and members of our senior leadership team. Succession planning to ensure effective transfer of knowledge and a seamless transition when key personnel depart is also important to our long-term success. Additionally, as we continue to make significant investments in new technologies and new business areas, we are increasingly dependent on being able to hire and retain technically skilled employees, including those with expertise in AI and machine learning.

Both external factors, such as fluctuations in economic and industry conditions, changes in U.S. immigration policies, regulatory changes, political forces and the competitive landscape, and internal factors, such as employee tolerance for changes in our corporate culture, organizational changes, limited remote working opportunities, and our compensation programs, may impact our ability to effectively manage our workforce. Further, employee compensation and benefit costs may increase due to inflationary pressures, and if our compensation does not keep up with inflation or that of our competitors’, we may see increased employee dissatisfaction and departures or difficulty in recruiting new employees. If key employees depart or we are unable to recruit and integrate new employees successfully, our business could be negatively impacted.

System failures and business disruptions may prevent us from providing reliable service, which could materially and adversely affect our reputation and financial condition.

We rely upon systems and networks – those of third-party suppliers and other providers, in addition to our own – to provide services to our customers. System, network, or infrastructure failures resulting from one of several potential causes may prevent us from providing reliable service or otherwise operate our business. Examples of these risks include:

physical damage, power surges or outages, equipment failure, or other service disruptions with respect to both our wireless and wireline networks, including those resulting from severe weather, storms, earthquakes, floods, hurricanes, wildfires and other natural disasters, which may occur more frequently or with greater intensity as a result of global climate change, public health crises, terrorist attacks, political instability and volatility and acts of war;
human error due to factors such as poor change management or policy compliance;
risks to our access to and use of reliable energy and water;
hardware or software failures or outages of our business systems or communications network;
supplier failures or delays; and
shifts in physical conditions due to climate change, such as sea-level rise or changes in temperature or precipitation patterns, which may impact the operating conditions of our infrastructure or other infrastructure we rely on.

Such events could cause us to lose customers and revenue, incur expenses, suffer reputational damage, and subject us to fines, penalties, adverse actions or judgments, litigation, or governmental investigations. Remediation costs could include liability for information loss, costs of repairing infrastructure and systems, and/or costs of incentives offered to customers. Our insurance may not cover or may not be adequate to fully reimburse us for costs and losses associated with such events, and such events may also impact the availability of insurance at costs and other terms we find acceptable for future events.

The scarcity and cost of additional wireless spectrum, and regulations relating to spectrum use, may adversely affect our business, financial condition, and operating results.

We continue to acquire and deploy new spectrum to expand and deepen our 5G coverage, maintain our quality of service, meet increasing or changing customer demands, and deploy new technologies. In order to expand and differentiate our services from our competitors, we will continue to actively seek to make additional investments in new spectrum, which could be significant. However, we may be unable to secure the additional spectrum necessary to maintain or enhance our competitive position on favorable terms or at all.

The continued interest in acquiring spectrum by existing carriers and others, including speculators, may reduce our ability to acquire or renew spectrum holdings (such as 2.5Ghz), and/or increase the cost of spectrum that is made available in the secondary markets and government auctions. Additionally, the FCC may be unable to make sufficient additional spectrum available for auction to meet the demand from all interested parties. As a result, any such spectrum that is made available at auction may be subject to heightened competition and priced beyond levels we are able or willing to pay.

Even if new spectrum becomes available to us, the FCC or other government entities may impose conditions on the acquisition and use of such spectrum, such as the configuration or geographic areas in which the spectrum may be deployed. These conditions may substantially increase the costs we incur or negatively affect the value of the spectrum to our business.
If we cannot acquire needed spectrum from the government or otherwise, if competitors acquire spectrum that will allow them to provide services competitive with our services, or if we cannot deploy services over acquired spectrum on a timely basis without burdensome conditions, at reasonable cost, and while maintaining network quality levels, our ability to attract and retain customers and our business, financial condition and operating results could be materially and adversely affected.

Any acquisition, divestiture, investment, joint venture or merger may subject us to significant risks, any of which may harm our business.

We may pursue acquisitions of, investments in, or joint ventures or mergers with, other companies, or the acquisition of technologies, services, products or other assets that we believe would complement or expand our business. We may also elect to divest some of our assets to third parties. Some of these potential transactions could be significant relative to the size of our business and operations. Any such transaction would involve a number of risks and could present financial, managerial and operational challenges, including:

diversion of management attention from running our existing business;
increased costs to integrate the networks, spectrum, technology, personnel, customer base, distributors and business partners and business practices of the company involved in any such transaction with our business;
increased interest expense and leverage or limits on other uses of cash;
potential loss of talent during integration due to differences in culture, locations, or other factors;
difficulties in effectively integrating the financial, operational and sustainability systems of the business involved in any such transaction into (or supplanting such systems with) our financial, operational and sustainability reporting infrastructure and internal control framework in an effective and timely manner;
risks of entering markets in which the Company has no or limited experience and where competitors have stronger market positions;
potential exposure to material liabilities not discovered in the due diligence process or as a result of any litigation arising in connection with any such transaction;
significant transaction-related expenses in connection with any such transaction, whether consummated or not;
risks related to our ability to obtain any required regulatory approvals necessary to consummate any such transaction; and
any business, technology, service, or product involved in any such transaction may significantly under-perform relative to our expectations, and we may not achieve the benefits we expect from the transaction, which could, among other things, also result in a write-down of goodwill and other intangible assets associated with such transaction.

We have entered into joint venture agreements aimed at establishing a robust fiber broadband network that complements our fixed wireless services. Once closed, differences in views among the joint venture participants may result in delayed decisions or disputes. Operating through joint ventures in which we do not hold a majority ownership interest results in us having limited control over many decisions made with respect to the businesses of the joint ventures. We also cannot control the actions of our joint venture partners. These joint ventures may not be subject to the same requirements regarding internal controls and internal
16

Table of Contents
control over financial reporting that we follow. As a result, internal control problems may arise with respect to these joint ventures. Any of these risks could have a material adverse effect on our business, financial condition and results of operations and could also affect our reputation.

Additionally, in connection with our merger (the “Merger”) with Sprint Corporation (“Sprint”) and related transactions, including the acquisition by DISH of certain prepaid wireless business (the “Prepaid Transaction” and, collectively, the “Transactions”), we agreed to fulfill various government commitments (the “Government Commitments”), including, among others, extensive 5G network build-out, delivering high-speed wireless services to the vast majority of Americans and marketing our in-home fixed wireless product to households where spectrum capacity is sufficient, as well as commitments related to national security, pricing and availability of rate plans. These Government Commitments materially increased our compliance obligations and could result in additional expenses and/or penalties in the future. In connection with the Prepaid Transaction, we and DISH entered into certain arrangements, including a Master Network Services Agreement (the “MNSA”), pursuant to which we provide DISH, for a period of seven years, network services for certain end users and infrastructure mobile network operator services to assist in the access and integration of the DISH network.

Any failure to fulfill our obligations under the Government Commitments and the MNSA in a timely manner could result in substantial fines, penalties, or other legal and administrative actions, liabilities, and reputational harm.

Economic, political and market conditions may adversely affect our business, financial condition, and operating results.

Our business, financial condition, and operating results are sensitive to changes in general economic conditions, including interest rates, consumer credit conditions, consumer debt levels, consumer confidence, unemployment rates, economic growth, energy costs, rates of inflation (or concerns about deflation), supply chain disruptions, impacts of current geopolitical conflict or instability, such as the Ukraine-Russia and Israel-Hamas wars and further escalations thereof, and other macroeconomic factors.

The wireless industry, broadly, is dependent on population growth, as a result, we expect the wireless industry’s customer growth rate to be moderate in comparison with historical growth rates, leading to ongoing competition for customers. In addition, the Government Commitments place certain limitations on our ability to increase prices, which limits our ability to pass along growing costs to customers. Rising prices for goods, services, and labor due to inflation could adversely impact our margins and/or growth.

Our services and device financing plans are available to a broad customer base, a significant segment of which may be vulnerable to weak economic conditions, particularly our subprime customers. We may have greater difficulty in gaining new customers within this segment, and existing customers may be more likely to terminate service and default on device financing plans due to an inability to pay.

Weak economic and credit conditions may also adversely impact our suppliers, dealers, wholesale partners or MVNOs, and enterprise and government customers, some of which may file for bankruptcy, or may experience cash flow or liquidity problems, or may be unable to obtain or refinance credit such that they may no longer be able to operate. Any of these could adversely impact our ability to distribute, market, or sell our products and services.

If we do not successfully deliver new products and services, we may not realize our intended growth targets or generate the expected returns from our business, adversely affecting our financial condition, and operating results.

We continue to expand our offerings beyond traditional wireless services to include High Speed Internet (including fiber broadband), advertising technology and services, and specialized network solutions, such as network slicing for first responders (T-Priority) and 5G advanced network solutions (ANS) for enterprises. These new ventures require significant capital, expertise, and operational support, and their success depends on factors we cannot fully control or predict. Increased competition, technical challenges, security concerns, operational complexities, or shifting regulatory landscapes could delay product rollouts, inflate costs, or limit adoption rates. Additionally, entering new markets or lines of business may expose us to unfamiliar regulatory requirements, compliance challenges, or damage existing customer relationships. Should these new products and services fail to gain traction, generate expected returns, or deliver value to customers, we could incur substantial expenses without offsetting revenue gains, adversely affecting our business, financial condition, and operating results.

17

Table of Contents
We rely on third parties to provide products and services for the operation of our business, and the failure or inability of such parties to provide these products or services could adversely affect our business, financial condition, and operating results.

We have a diverse set of suppliers to help us develop, maintain, and troubleshoot products and services such as wireless and wireline network components, software development services, and billing and customer service support. However, in certain areas such as, billing services, voice, and data communications transport services, wireless or wireline network infrastructure equipment, handsets, other devices, back-office processes and payment processing, there are a limited number of suppliers who can provide adequate support for us, which decreases our flexibility to switch to alternative third parties. Unexpected termination of our arrangement with any of these suppliers or difficulties in renewing our commercial arrangements with them could have a material and adverse effect on our business operations.

Our suppliers are also subject to their own risks, including, but not limited to, cybersecurity, economic, financial and credit conditions, labor force disruptions, geopolitical tensions, disruptions in global supply chain and the risks of natural catastrophic events (such as earthquakes, floods, hurricanes, storms, heatwaves and fires), energy shortages, power outages, equipment failures, terrorist attacks or other hostile acts, and public health crises, such as the COVID-19 pandemic, which may result in performance below the levels required by their contracts. Our business could be severely disrupted if critical suppliers or service providers fail to comply with their contracts or if we experience delays or service degradation during any transition to a new outsourcing provider or other supplier or if we are required to replace the supplied products or services with those from another source, especially if the replacement becomes necessary on short notice. Any such disruptions could have a material adverse effect on our business, financial condition, and operating results.

Further, some of our suppliers may provide services from outside of the United States, which carries additional regulatory and legal obligations. We rely on suppliers to provide us with contractual assurances and to disclose accurate information regarding risks associated with their provision of products or services in accordance with our policies and standards, including our Supplier Code of Conduct and our third-party risk management practices. The failure of our suppliers to comply with our expectations and policies could expose us to additional legal and litigation risks and lead to unexpected contract terminations.

Additionally, we rely on third-party technology partners on various projects and developments. If any of our third-party technology partners terminate or reduce their relationships with us or suspend, limit, or cease their operations, we may not be able to complete such initiatives or achieve the intended results from the partnerships, and our business, reputation, financial condition and results of operations may suffer.

Sociopolitical volatility and polarization may adversely affect our business operations and reputation.

The current sociopolitical environment is characterized by deep complexity, volatility, and polarization on various social and political issues. The increasing intersection of technology and politics has led to rapid and unpredictable shifts in public sentiment. Social media and digital platforms have amplified the voices of various stakeholders, creating the potential for swift change in public opinion and stronger reactions to corporate actions. As a company that sells products and services across the nation to millions of customers, these dynamics increase the risk of potential reputational damage, boycotts, and shifts in consumer behavior that could adversely affect our brand, sales and profitability. Our ability to respond effectively, sensitively, and authentically to the expectations and concerns of our customers, employees, and other stakeholders is key to mitigating these risks. If we are unable to manage these challenges effectively, there may be adverse impacts to our business, reputation, financial condition, and operating results.

Additionally, we are subject to emerging and evolving regulatory requirements and frameworks regarding environmental, social and governance matters, including potential new or revised disclosure rules proposed by the SEC and recently enacted or proposed legislation in jurisdictions such as California. The ultimate scope of these regulations may change as they are finalized, and they may not be uniform across jurisdictions. Meeting these obligations may require significant investments of time, capital, and personnel.

Risks Related to Our Indebtedness

Our substantial level of indebtedness could adversely affect our business flexibility and ability to service our debt, and increase our borrowing costs.

We have, and we expect that we will continue to have, a substantial amount of debt. Our substantial level of indebtedness could have the effect of, among other things, reducing our flexibility in responding to changing business, economic, market and industry conditions and increasing the amount of cash required to service our debt. In addition, this level of indebtedness may
18

Table of Contents
also reduce funds available for capital expenditures, any Board-approved share repurchases, dividends or other activities. Those impacts may put us at a competitive disadvantage relative to other companies with lower debt levels. Further, we may incur substantial additional indebtedness in the future, subject to the restrictions contained in our debt instruments, if any, which could increase the risks associated with our capital structure.

Our ability to service our substantial debt obligations will depend on future performance, which will be affected by business, economic, market and industry conditions and other factors. There is no guarantee that we will be able to generate sufficient cash flow to service our debt obligations when due. If we are unable to meet such obligations or fail to comply with the financial and other restrictive covenants contained in the agreements governing such debt obligations, we may be required to refinance all or part of our debt, sell important strategic assets at unfavorable prices or make additional borrowings. We may not be able to, at any given time, refinance our debt, sell assets, or make additional borrowings on commercially reasonable terms or at all, which could have a material adverse effect on our business, financial condition, and operating results.

Changes in credit market conditions and other factors could adversely affect our ability to raise debt favorably.

Instability in the global financial markets, inflation, policies of various governmental and regulatory agencies, including changes in monetary policy and interest rates, and other general economic conditions could lead to volatility in the credit and equity markets. This volatility could limit our access to the capital markets, leading to higher borrowing costs or, in some cases, the inability to obtain financing on terms that are acceptable to us or at all. Further, deterioration in our operating performance may lead to a decrease in our credit ratings, which could also impact our ability to access the debt capital markets at rates favorable or acceptable to us.

In addition, any hedging agreements we may enter into to limit our exposure to interest rate increases or foreign currency fluctuations may not offer complete protection from these risks or may be unsuccessful, and consequently may effectively increase the interest rate we pay on our debt or the exchange rate with respect to any debt we may incur in a foreign currency, and any portion not subject to such hedging agreements would have full exposure to interest rate increases or foreign currency fluctuations, as applicable. If any financial institutions that are parties to our hedging agreements were to default on their payment obligations to us, declare bankruptcy or become insolvent, we would be unhedged against the underlying exposures. Any posting of collateral by us under our hedging agreements and the modification or termination of any of our hedging agreements could negatively impact our liquidity or other financial metrics. Any of these risks could have a material adverse effect on our business, financial condition, and operating results.

Risks Related to Legal and Regulatory Matters

Failure to maintain effective internal control over financial reporting could impair our compliance with Section 404 of the Sarbanes-Oxley Act, which could lead to material misstatements in our financial statements and adversely affect our operations and reputation.

We rely on robust internal controls to provide reasonable assurance regarding the reliability of our financial information and the preparation of our financial statements. These controls include, among other things, properly designed processes, clear policies and procedures, competent personnel, effective oversight functions, and reliable information systems that facilitate the collection, processing, and communication of financial data. As we continue to refine and improve our systems to align with our evolving business needs, there is no assurance that these improvements will be implemented without delays or disruptions. A failure or significant delay in updating our systems, or a failure to effectively integrate new systems with existing processes, could compromise the effectiveness of our internal controls. If our internal controls are not effectively designed or properly implemented, or if changes to our business processes or organizational structure outpace our internal controls’ ability to adapt, we could experience material weaknesses or other deficiencies.

Any material weaknesses or other control deficiencies that may arise in the future could require significant time and resources to remediate. If we are unable to remediate material weaknesses in internal control over financial reporting, then our ability to analyze, record and report financial information free of material misstatements, to prepare financial statements within the time periods specified by the rules and forms of the SEC and otherwise to comply with the requirements of Section 404 of the Sarbanes-Oxley Act would be negatively impacted. As a result, we could face legal fines and penalties, diminished investor confidence, and adverse impacts on our access to the capital markets, potentially resulting in a decline in our stock price and harm to our reputation.

Changes in regulations or in the regulatory framework under which we operate could adversely affect our business, financial condition, and operating results.

We are subject to regulatory oversight by various federal, state, and local agencies, as well as judicial review and actions, on issues related to the wireless industry that include, but are not limited to, roaming, interconnection, spectrum allocation and licensing, facilities siting, pole attachments, intercarrier compensation, Universal Service Fund (“USF”), 911 services, robocalling/robotexting, consumer protection, consumer privacy, and cybersecurity. We are also subject to regulations in connection with other aspects of our business, including device financing and insurance activities.

The FCC regulates the licensing, construction, modification, operation, ownership, sale, and interconnection of wireless communications systems, as do some state and local regulatory agencies. In particular, the FCC imposes significant regulation on licensees of wireless spectrum with respect to how radio spectrum is used by licensees or at what power levels, the nature of the services that licensees may offer and how the services may be offered, and the resolution of issues of interference between operators in the same or adjacent spectrum bands. Changes necessary to resolve interference issues or concerns may have a significant impact on our ability to fully utilize our spectrum. Additionally, the FTC and other federal and state agencies have asserted that they have jurisdiction over some consumer protection matters, and the elimination and prevention of anticompetitive business practices with respect to the provision of wireless products and services.

We cannot assure that the FCC or any other federal, state, or local agencies will not adopt or change regulations, change or discontinue existing programs, implement new programs, or take enforcement or other actions that would adversely affect our business, impose new costs, or require changes in current or planned operations, including timing of the shutdown of legacy technologies.

We also face potential investigations by, and inquiries from or actions by state public utility commissions. We also cannot assure that Congress will not amend the Communications Act, from which the FCC obtains its authority, and which serves to limit state authority, or enact other legislation in a manner that could be adverse to our business.

Further, government funded programs may be discontinued due to ongoing legal challenges to the FCC’s funding mechanism, which could result in the reduction in subsidies for low-income customers and the associated revenue.

Failure to comply with applicable regulations could have a material adverse effect on our business, financial condition, and operating results. We could be subject to fines, forfeitures, and other penalties (including, in extreme cases, revocation of our spectrum licenses) for failure to comply with the FCC or other governmental regulations, even if any such noncompliance was unintentional. The loss of any licenses, or any related fines or forfeitures, could adversely affect our business, financial condition, and operating results.

Laws and regulations relating to the handling of privacy, data protection and AI may result in increased costs, legal claims, fines against us, or reputational damage.

Since 2020, more than a dozen states have enacted new, comprehensive privacy laws that create new data privacy rights for residents of those states and new compliance obligations for us and the industry in general, in addition to private rights of action for certain types of data breaches. These include the California Consumer Privacy Act (“CCPA”) and similar laws in other states. Pending legislation in a number of other states would create similar laws elsewhere. All of these new privacy laws and others that we expect to be developed and enacted going forward will impose additional data protection obligations and potential liability on companies such as ours doing business in those states. Further, privacy laws also limit our ability to collect and use personal information.

We have incurred and will continue to incur significant implementation costs to ensure compliance with the CCPA, new privacy laws in other states, and their related regulations, including managing the complexity of laws that vary from state to state. Both federal and state governments are considering additional privacy laws and regulations which, if passed, could further impact our business, strategies, offerings, and initiatives and cause us to incur further costs. Any actual or perceived failure to comply with the CCPA, other data privacy laws or regulations, or related contractual or other obligations, or any perceived privacy rights violation, could lead to investigations, claims, and proceedings by governmental entities and private parties, damages for contract breaches, and other significant costs, penalties, and other liabilities, as well as harm to our reputation and market position.

AI-related laws and regulations continue to remain uncertain and may vary from jurisdiction to jurisdiction. Our obligations to comply with the evolving legal and regulatory landscape may require us to incur significant additional costs or limit our ability to incorporate certain AI capabilities into our business operations or product offerings. As we integrate AI technologies into our
20

Table of Contents
business, we must navigate varying regulations that could impact our operations and product development. Failure to comply with these regulations could result in fines, penalties, or restrictions on our use of AI, which could adversely affect our business.

Unfavorable outcomes of legal proceedings may adversely affect our business, reputation, financial condition, cash flows and operating results.

We and our affiliates are involved in various disputes, governmental and/or regulatory inspections, investigations and proceedings, mass arbitrations and litigation matters. For more information, see “– Contingencies and Litigation – Litigation and Regulatory Matters” in Note 18 – Commitments and Contingencies of the Notes to the Consolidated Financial Statements.

In addition, we, along with equipment manufacturers and other carriers, are subject to current and potential future lawsuits alleging adverse health effects arising from the use of wireless handsets or from wireless transmission equipment such as cell towers. In addition, the FCC has from time to time gathered data regarding wireless device emissions, and its assessment of the risks associated with using wireless devices may evolve based on its findings. Any of these allegations or changes in risk assessments could result in customers purchasing fewer devices and wireless services, could result in significant legal and regulatory liability, and could have a material adverse effect on our business, reputation, financial condition, cash flows and operating results.

Such legal proceedings can be complex, costly, and highly disruptive to our business operations by diverting the attention and energy of management and other key personnel. The assessment of the outcome of legal proceedings, including our potential liability, if any, is a highly subjective process that requires judgments about future events that are not within our control. The amounts ultimately received or paid upon settlement or pursuant to final judgment, order or decree may differ materially from amounts accrued in our financial statements. In addition, litigation or similar proceedings could impose restraints on our current or future manner of doing business. Such potential outcomes including judgments, awards, settlements or orders could have a material adverse effect on our business, reputation, financial condition, cash flows and operating results.

Our business may be adversely impacted if we are not able to protect our intellectual property rights or if we infringe on the intellectual property rights of others.

We rely on a variety of intellectual property assets, including patents, copyrights, trademarks, and domains, to maintain our competitiveness. If we are unable to protect our intellectual property due to factors such as changes in US intellectual property laws, the value of our intellectual property may become impaired, which may adversely impact our business and financial results.

Additionally, we have faced and will continue to face various litigations alleging that our products or services infringe patents or other intellectual property of third parties, including potential litigation arising from our use of AI. If successful, these litigations could result in an award of financial compensation, including damages or royalties, business disruptions, reputational harm, or an order requiring that we cease offering, selling, and using the relevant products, equipment, services, and network functions. Defending against such litigation is not only costly and time-consuming, but it may also be disruptive to our business operations and divert resources and attention. Furthermore, the outcomes of these litigations are inherently uncertain.

Our suppliers and vendors also have and will continue to face intellectual property litigation related to the technology used in the products, equipment, and services they provide to us. If successful, such litigation against our suppliers and vendors might impact their ability to continue to provide the relevant products, equipment, and services to us.

We offer regulated financial services products. These products expose us to a wide variety of state and federal regulations.

The financing of devices, such as through our EIP, impact our regulatory compliance obligations. Failure to remain compliant with applicable regulations may increase our risk exposure in the following areas:

consumer complaints and potential examinations or enforcement actions by federal and state regulatory agencies, including, but not limited to, the Consumer Financial Protection Bureau, state attorneys general, the FCC and the FTC; and
regulatory fines, penalties, enforcement actions, civil litigation, and/or class action lawsuits. Failure to comply with applicable regulations and the realization of any of these risks could have a material adverse effect on our business, financial condition, and operating results.

Table of Contents
Our business may be impacted by new or amended tax laws or regulations or administrative interpretations and judicial decisions affecting the scope or application of tax laws or regulations.

In connection with the products and services we sell, we calculate, collect, and remit various federal, state, and local taxes, fees and regulatory charges (“tax” or “taxes”) to numerous federal, state and local governmental authorities, including federal and state USF contributions and common carrier regulatory charges and public safety fees. As many of our service plans offer taxes and fees inclusive, our business results could be adversely impacted by increases in taxes and fees. In addition, we incur and pay state and local transaction taxes and fees on purchases of goods and services used in our business.

Tax laws are dynamic and subject to change as new laws are passed and new interpretations of the laws are issued or applied. In many cases, the application of existing, newly enacted or amended tax laws may be uncertain and subject to different interpretations, especially when evaluated against new technologies and telecommunications services, such as broadband internet access and cloud-related services. Legislative changes, administrative interpretations and judicial decisions affecting the scope or application of tax laws could also impact revenue reported and taxes due on tax inclusive plans. Additionally, failure to comply with any of the tax laws could subject us to additional taxes, fines, penalties, or other adverse actions.

In the event that federal, state, and/or local municipalities were to significantly increase taxes and regulatory or public safety charges on our network, operations, or services, or seek to impose new taxes or charges, it could have a material adverse effect on our business, financial condition, and operating results.

Our wireless licenses are subject to renewal and may be revoked in the event that we violate applicable laws.

Our existing wireless licenses are subject to renewal upon the expiration of the period for which they are granted. Our licenses have been granted with an expectation of renewal, and the FCC generally has approved our license renewal applications. However, the Communications Act provides that licenses may be revoked for cause and license renewal applications denied if the FCC determines that a renewal would not serve the public interest. If we fail to timely file to renew any wireless license or fail to meet any regulatory requirements for renewal, including construction and substantial service requirements, we could be denied a license renewal. Many of our wireless licenses are subject to interim or final construction requirements, and there is no guarantee that the FCC will find our construction, or the construction of prior licensees, sufficient to meet the build-out or renewal requirements. Accordingly, we cannot assure that the FCC will renew our wireless licenses upon their expiration. If any of our wireless licenses were to be revoked or not renewed upon expiration, we would not be permitted to provide services under that license, which could have a material adverse effect on our business, financial condition, and operating results.

Risks Related to Ownership of Our Common Stock

Our Certificate of Incorporation designates the Court of Chancery of the State of Delaware as the sole and exclusive forum for certain actions and proceedings, which could limit the ability of our stockholders to obtain a judicial forum of their choice for disputes with the Company or its directors, officers or employees.

Our Certificate of Incorporation provides that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware shall be the sole and exclusive forum for (i) any derivative action or proceeding brought on behalf of the Company, (ii) any action asserting a claim of breach of a fiduciary duty owed by any director, officer or employee of the Company to the Company or its stockholders, (iii) any action asserting a claim arising pursuant to any provision of the General Corporation Law of the State of Delaware, the Certificate of Incorporation or the Company's bylaws or (iv) any other action asserting a claim arising under, in connection with, and governed by the internal affairs doctrine. This choice of forum provision does not waive our compliance with our obligations under the federal securities laws and the rules and regulations thereunder. Moreover, the provision does not apply to suits brought to enforce a duty or liability created by the Exchange Act or by the Securities Act of 1933, as amended.

This choice of forum provision may increase costs to bring a claim, discourage claims or limit a stockholder's ability to bring a claim in a judicial forum that the stockholder finds favorable for disputes with the Company or its directors, officers or employees, which may discourage such lawsuits against the Company and its directors, officers and employees, even though an action, if successful, might benefit our stockholders. Alternatively, if a court were to find the choice of forum provision to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such matters in other jurisdictions, which could increase our costs of litigation and adversely affect our business and financial condition.

DT controls a majority of the voting power of our common stock and the T-Mobile trademarks we utilize in our business and may have interests that differ from the interests of our other stockholders.

DT controls a majority of the voting power of our common stock and therefore we are a “controlled company,” as defined in the NASDAQ Stock Market LLC (“NASDAQ”) listing rules, and we are not subject to NASDAQ requirements that would otherwise require us to have a majority of independent directors, a nominating committee composed solely of independent directors or a compensation committee composed solely of independent directors. Accordingly, our stockholders will not be afforded the same protections as stockholders of other NASDAQ-listed companies generally receive with respect to corporate governance for so long as we rely on these exemptions from the corporate governance requirements.

In addition, pursuant to our Certificate of Incorporation and the Second Amended and Restated Stockholders’ Agreement, as long as DT beneficially owns 30% or more of our outstanding common stock, we are restricted from taking certain actions without DT’s prior written consent, including (i) incurring indebtedness above certain levels based on a specified debt to cash flow ratio, (ii) taking any action that would cause a default under any instrument evidencing indebtedness involving DT or its affiliates, (iii) acquiring or disposing of assets or entering into mergers or similar acquisitions in excess of $1.0 billion, (iv) changing the size of our Board of Directors, (v) subject to certain exceptions, issuing equity of 10% or more of the then-outstanding shares of our common stock, or issuing equity to redeem debt held by DT, (vi) repurchasing or redeeming equity securities or making any extraordinary or in-kind dividend other than on a pro rata basis, or (vii) making certain changes involving our CEO. We are also restricted from amending our Certificate of Incorporation and bylaws in any manner that could adversely affect DT’s rights under the Second Amended and Restated Stockholders’ Agreement for as long as DT beneficially owns 5% or more of our outstanding common stock. These restrictions could prevent us from taking actions that our Board of Directors might otherwise determine are in the best interests of the Company and our stockholders, or that may be in the best interests of our other stockholders.

DT effectively has control over all matters submitted to our stockholders for approval, including the election or removal of directors, changes to our Certificate of Incorporation, a sale or merger of our Company and other transactions requiring stockholder approval under Delaware law. DT’s controlling interest may have the effect of making it more difficult for a third party to acquire, or discouraging a third party from seeking to acquire, the Company and DT, as the controlling stockholder, may have strategic, financial, or other interests different from those of our other stockholders, including as the holder of a portion of our debt and as the counterparty in a number of commercial arrangements, and may make decisions adverse to the interests of our other stockholders.

In addition, we license certain trademarks from DT, including the right to use the trademark “T-Mobile” as a name for the Company and our flagship brand under a trademark license agreement, as amended, with DT. As described in more detail in our Proxy Statement on Schedule 14A filed with the SEC on April 24, 2024 under the heading “Transactions with Related Persons and Approval,” we are obligated to pay DT a royalty in an amount equal to 0.25% (the “royalty rate”) of the net revenue (as defined in the trademark license) generated by products and services sold by the Company under the licensed trademarks subject to a cap of $80 million per calendar year through December 31, 2028. We and DT are obligated to negotiate a new trademark license when (i) DT has 50% or less of the voting power of the outstanding shares of capital stock of the Company or (ii) any third party owns or controls, directly or indirectly, 50% or more of the voting power of the outstanding shares of capital stock of the Company, or otherwise has the power to direct or cause the direction of the management and policies of the Company. If we and DT fail to agree on a new trademark license, either we or DT may terminate the trademark license and such termination shall be effective, in the case of clause (i) above, on the third anniversary after a notice of termination and, in the case of clause (ii) above, on the second anniversary after a notice of termination. A further increase in the royalty rate or termination of the trademark license could have a material adverse effect on our business, financial condition, and operating results.

We cannot guarantee that our current and future stockholder return programs will be fully utilized or that they will enhance long-term stockholder value.

Our Board of Directors has authorized, and may from time to time authorize, stockholder return programs, consisting of repurchases of shares of our common stock, the payment of cash dividends, or both. The specific timing and amount of any share repurchases and any dividend payments under any stockholder return program will depend on prevailing share prices, general economic and market conditions, Company performance and other considerations, such as whether the Company determines that there are other uses for the funds currently authorized for the program that would be more advantageous for our business. In addition, the specific timing and amount of any dividend payments are subject to declaration on future dates by the Board of Directors in its sole discretion.

23

Table of Contents
Any stockholder return program could impact our cash flows and affect the trading price of our common stock and increase volatility. We cannot guarantee that any stockholder return program will be fully consummated or that it will enhance long-term stockholder value. Our current and future stockholder return programs do not, and will not, obligate the Company to acquire any particular amount of common stock or to declare and pay any particular amount of dividends, and any program may be suspended or discontinued at any time at the Company’s discretion. Any announcement of termination of any program may result in a decrease in the price of our common stock.

Future sales of our common stock by DT and SoftBank and foreign ownership limitations by the FCC could have a negative impact on our stock price and decrease the value of our stock.

We cannot predict the effect, if any, that market sales of shares of our common stock by DT or SoftBank will have on the prevailing trading price of our common stock. Sales of a substantial number of shares of our common stock could cause our stock price to decline.

We and DT are parties to the Second Amended and Restated Stockholders’ Agreement pursuant to which DT is free to transfer its shares in public sales without notice, as long as such transactions would not result in a third party owning more than 30% of the outstanding shares of our common stock. If a transfer were to exceed the 30% threshold, it would be prohibited unless the transfer were approved by our Board of Directors, or the transferee were to make a binding offer to purchase all of the other outstanding shares on the same price and terms. The Second Amended and Restated Stockholders’ Agreement does not otherwise impose any other restrictions on the sales of common stock by DT. Moreover, the Second Amended and Restated Stockholders’ Agreement generally requires us to cooperate with DT to facilitate the resale of our common stock or debt securities held by DT under shelf registration statements we have filed.

The sale of shares of our common stock by DT or SoftBank (other than in transactions involving the purchase of all of our outstanding shares) could significantly increase the number of shares available in the market, which could cause a decrease in our stock price. In addition, even if DT or SoftBank does not sell a large number of their shares into the market, their rights to transfer a large number of shares into the market could depress our stock price.

Furthermore, under existing law, no more than 20% of an FCC licensee’s capital stock may be directly owned, or no more than 25% indirectly owned, or voted by non-U.S. citizens or their representatives, by a foreign government or its representatives or by a foreign corporation. If an FCC licensee is controlled by another entity, up to 25% of that entity’s capital stock may be owned or voted by non-U.S. citizens or their representatives, by a foreign government or its representatives or by a foreign corporation. Foreign ownership above the 25% holding company level may be allowed if the FCC finds such higher levels consistent with the public interest. The FCC has ruled that higher levels of foreign ownership, even up to 100%, are presumptively consistent with the public interest with respect to investors from certain nations. If our foreign ownership by previously unapproved foreign parties were to exceed the permitted level without further FCC authorization, the FCC could subject us to a range of penalties, including an order for us to divest the foreign ownership in part, fines, license revocation or denials of license renewals. If ownership of our common stock by an unapproved foreign entity were to become subject to such limitations, or if any ownership of our common stock violates any other rule or regulation of the FCC applicable to us, our Certificate of Incorporation provides for certain redemption provisions at a pre-determined price which may be less than fair market value. These limitations and our Certificate of Incorporation may limit our ability to attract additional equity financing outside the United States and decrease the value of our common stock.

Table of Contents

Cyber risk management is a core component of the Company's governance structure. We utilize the National Institute of Standards and Technology’s Cybersecurity Framework as a guide in cyber risk management to identify, assess, and assist the CSO in managing cybersecurity risks. Cyber risk management encompasses partnerships among teams that are responsible for cyber governance, prevention, detection, and remediation activities within the Company’s cybersecurity environment. As part of our cyber risk management efforts, we conduct periodic reviews and collaborate with enterprise-wide risk assessments to assess and manage cybersecurity risks. Our cybersecurity team also provides enterprise-wide cybersecurity training for employees to continuously improve our mitigation against human-driven vulnerabilities.

Our management also conducts a quarterly enterprise-wide risk assessment that considers a wide spectrum of risks facing the Company, including cybersecurity. Through these quarterly risk assessments, management informs the Audit Committee on the cyber risk landscape facing the Company and the Company’s preparedness to manage such risk. The enterprise-wide risk assessment is a top-down risk assessment that leverages the assessments performed by cyber risk management.


The Company engages top-tier external cyber security firms, as needed, leveraging their expertise as part of our ongoing effort to evaluate and enhance our cybersecurity program. They help with cyber defense capabilities (including staff enhancement of certain functions) and transformation to mitigate associated threats, reduce risk, enhance our cybersecurity posture, and meet the Company's evolving needs.


Our third-party risk management program includes processes for identifying and managing material cybersecurity risks arising from third-party providers. Our third-party risk management program actively engages with the enterprise-wide risk assessment process and partners with cyber risk management to report relevant risks to the NCG Committee, the Audit Committee and our internal Enterprise Risk & Compliance Committee. Our third-party risk management program includes cybersecurity as an aspect of its risk assessment of third parties with the objective that key risks are identified and addressed. Moreover, the program also considers risks associated with certain fourth parties, entities that are partners or subcontractors of our direct third-party vendors, through assessments carried out by our third-party service providers.

Cybersecurity Incident Impact

For additional details regarding the impact of both cybersecurity incidents, see Note 18 – Commitments and Contingencies of the Notes to the Consolidated Financial Statements.

Prepaid revenues increased $632 million, or 6%, primarily from:

Higher average prepaid customers, primarily from the prepaid customers acquired through the Ka’ena Acquisition; partially offset by
Lower prepaid ARPU. See “Prepaid ARPU” in the “Performance Measures” section of this MD&A.

Wholesale and other service revenues decreased $1.3 billion, or 28%, primarily from:

Lower MVNO revenues, including the impact from the Ka’ena Acquisition, and lower DISH and TracFone MVNO revenue;
Lower Affordable Connectivity Program and Lifeline revenues; and
Lower Wireline revenues due to the sale of the Wireline Business on May 1, 2023.

A decrease of $231 million in device sales revenue, excluding purchased leased devices, primarily from:
A net decrease in the total number of devices sold, driven by lower Assurance Wireless and prepaid devices, partially offset by higher postpaid devices; partially offset by
Higher average revenue per device sold, net of promotions, primarily driven by an increase in the high-end phone mix; and
A decrease of $219 million in lease revenues, primarily due to a lower number of customer devices under lease as a result of the continued strategic shift in device financing from leasing to EIP.

Other revenues decreased $220 million, or 19%, primarily from the transition of certain device recovery programs from external sources to in-house processing, resulting in a change in presentation from Other revenues to Equipment revenues.

Total operating expenses decreased $902 million, or 1%. The components of this change are discussed below.

Cost of services, exclusive of depreciation and amortization, decreased $884 million, or 8%, primarily from:

A decrease of $472 million in Merger-related costs related to network decommissioning and integration;

$321 million of severance and related costs associated with the August 2023 workforce reduction recognized in the prior year;
$202 million of gains associated with the closing of certain spectrum exchange transactions and $105 million of legal-related insurance recoveries recognized during the year ended December 31, 2024; and

Guarantor Financial Information

Pursuant to the applicable indentures and supplemental indentures, the Senior Notes to affiliates and third parties issued by T-Mobile USA, Inc., Sprint and Sprint Capital Corporation (collectively, the “Issuers”) are fully and unconditionally guaranteed, jointly and severally, on a senior unsecured basis by T-Mobile (“Parent”) and certain of Parent’s 100% owned subsidiaries (“Guarantor Subsidiaries”).

The guarantees of the Guarantor Subsidiaries are subject to release in limited circumstances only upon the occurrence of certain customary conditions. Generally, the guarantees of the Guarantor Subsidiaries with respect to the Senior Notes issued by T-Mobile USA, Inc. (other than $3.5 billion in principal amount of Senior Notes issued in 2017 and 2018) and the credit agreement entered into by T-Mobile USA, Inc. will be automatically and unconditionally released if, immediately following such release and any concurrent releases of other guarantees, the aggregate principal amount of indebtedness of non-guarantor subsidiaries (other than certain specified subsidiaries) would not exceed $2.0 billion. The indentures, supplemental indentures and credit agreements governing the long-term debt contain covenants that, among other things, limit the ability of the Issuers or borrowers and the Guarantor Subsidiaries to incur more debt, create liens or other encumbrances, and to merge, consolidate or sell, or otherwise dispose of, substantially all of their assets.

Basis of Presentation

Adjusted Free Cash Flow increased $3.4 billion, or 25%, for the year ended December 31, 2024, primarily from:

Higher Net cash provided by operating activities, as described above; and
Lower Cash purchases of property and equipment, including capitalized interest, driven by increased capital efficiencies from accelerated investments in our nationwide 5G network in previous years; partially offset by
Lower Proceeds related to beneficial interests in securitization transactions, which were offset in Net cash provided by operating activities.
Adjusted Free Cash Flow includes the impact of $767 million and $2.0 billion for the years ended December 31, 2024 and 2023, respectively, in net payments for Merger-related costs.

During the years ended December 31, 2024 and 2023, there were no significant net cash proceeds from securitization.

On October 22, 2024, we executed amendments (the “Pledge Amendments”) to the EIP Sale Arrangement and the Service Receivable Sale Arrangement (as discussed in Note 5 – Sales of Certain Receivables of the Notes to the Consolidated Financial Statements). Following the effective date of the Pledge Amendments of November 1, 2024, all cash proceeds associated with the sale of such receivables, a portion of which, prior to November 1, 2024, were recognized as Proceeds related to beneficial interests in securitization transactions within Net cash used in investing activities on our Consolidated Statements of Cash Flows, were recognized as operating cash flows. The Pledge Amendments did not have a net impact on Adjusted Free Cash Flow.

Borrowing Capacity

We maintain a revolving credit facility (the “Revolving Credit Facility”) with an aggregate commitment amount of $7.5 billion. As of December 31, 2024, there was no outstanding balance under the Revolving Credit Facility.

We maintain an unsecured short-term commercial paper program with the ability to borrow up to $2.0 billion from time to time. This program supplements our other available external financing arrangements and proceeds are expected to be used for general corporate purposes. As of December 31, 2024, there was no outstanding balance under this program.

Debt Financing

As of December 31, 2024, our total debt and financing lease liabilities were $80.6 billion, excluding our tower obligations, of which $74.2 billion was classified as long-term debt and $1.2 billion was classified as long-term financing lease liabilities.

During the year ended December 31, 2024, we issued long-term debt for net proceeds of $8.6 billion and repaid short-term debt with an aggregate principal amount of $5.1 billion.

For more information regarding our debt financing transactions, see Note 9 – Debt of the Notes to the Consolidated Financial Statements.

Spectrum Auctions

In September 2022, the FCC announced that we were the winning bidder of 7,156 licenses in Auction 108 (2.5 GHz spectrum) for an aggregate price of $304 million. At inception of Auction 108 in June 2022, we deposited $65 million. We paid the FCC the remaining $239 million for the licenses won in the auction in September 2022. On February 29, 2024, the FCC issued to us the licenses won in Auction 108, and substantially all of these licenses were deployed in March 2024.

For more information regarding our spectrum licenses, see Note 7 – Goodwill, Spectrum License Transactions and Other Intangible Assets of the Notes to the Consolidated Financial Statements.

License Purchase Agreements

On August 8, 2022, we entered into License Purchase Agreements to acquire spectrum in the 600 MHz band from Channel 51 License Co LLC and LB License Co, LLC (together with Channel 51 License Co LLC, the “Sellers”) in exchange for total cash consideration of $3.5 billion. On March 30, 2023, we and the Sellers entered into Amended and Restated License Purchase Agreements, pursuant to which we and the Sellers agreed to bifurcate the transaction into two tranches of licenses, with the closings on the acquisitions of certain licenses in Chicago, Dallas and New Orleans being deferred in order to potentially expedite the regulatory approval process for the remainder of the licenses. Subsequently, on August 25, 2023, we and the Sellers entered into Amendments No. 1 to the Amended and Restated License Purchase Agreements, whereby we deferred the closings of certain additional licenses in Chicago and Dallas into the second closing tranche. Together, the licenses with closings deferred into the second closing tranche represent approximately $1.1 billion of the aggregate $3.5 billion cash consideration.

The FCC approved the purchase of the first tranche on December 29, 2023. The first tranche closed on June 24, 2024, and the associated payment of $2.4 billion was made on August 5, 2024.

The FCC approved the purchase of the Dallas licenses included in the second tranche on October 22, 2024. The purchase of the Dallas licenses closed on December 6, 2024, and the associated payment of $541 million was made on the same day.

We anticipate that the remaining deferred licenses from the second tranche of $604 million will close in 2025.

The parties have agreed that each of the closings will occur within 180 days after the receipt of the applicable required regulatory approvals, and payment of each portion of the aggregate $3.5 billion purchase price will occur no later than 40 days after the date of each respective closing.

On September 12, 2023, we entered into a License Purchase Agreement with Comcast pursuant to which we will acquire spectrum in the 600 MHz band from Comcast in exchange for total cash consideration of between $1.2 billion and $3.3 billion, subject to an application for FCC approval. The licenses are subject to an exclusive leasing arrangement between us and Comcast entered into contemporaneously with the License Purchase Agreement. On January 13, 2025, we and Comcast entered into an amendment to the License Purchase Agreement pursuant to which we will acquire additional spectrum. Subsequent to the amendment, the total cash consideration for the transaction is between $1.2 billion and $3.4 billion. We anticipate the closing will occur in the first half of 2028.

On September 10, 2024, we entered into a License Purchase Agreement with N77 License Co LLC (“Buyer”), pursuant to which Buyer has the option to purchase all or a portion of our remaining 3.45 GHz spectrum licenses in exchange for a range of cash consideration, with the specific licenses sold to be determined based upon the amount of committed financing raised by Buyer. As of December 31, 2024 and 2023, the licenses subject to the License Purchase Agreement were held at cost of $2.7 billion in Spectrum licenses on our Consolidated Balance Sheets. We maintain the right to terminate the License Purchase

Agreement no later than February 7, 2025, as we did not receive written notice of committed financing as of December 9, 2024, from the Buyer at or above a certain target level of cash consideration. If we do not terminate the License Purchase Agreement, the transaction is subject to FCC approval.

Acquisition of Ka’ena Corporation

On the Acquisition Date, we completed the Ka’ena Acquisition. The total purchase price is variable, dependent upon specified performance indicators of Ka’ena, and consists of an upfront payment on the Acquisition Date and an earnout payable on August 1, 2026. On the Acquisition Date and in satisfaction of the upfront payment, we transferred $420 million in cash and 3,264,952 shares of T-Mobile common stock valued at $536 million as determined based on its closing market price on April 30, 2024, for a total payment fair value of $956 million. The amount of the upfront payment was subject to customary adjustments and as a result of such adjustments, $17 million of the upfront payment was returned to T-Mobile during the fourth quarter of 2024, which resulted in a commensurate increase in the maximum payable in satisfaction of the earnout.

Based on the adjusted amount paid upfront, up to an additional $420 million in future cash and T-Mobile common stock is payable in satisfaction of the earnout, dependent upon Ka’ena’s achievement of specified performance indicators.

For more information regarding the Ka’ena Acquisition, see Note 2 – Business Combinations of the Notes to the Consolidated Financial Statements.

Lumos Joint Venture

On April 24, 2024, we entered into a definitive agreement with Fund VI to establish a joint venture between us and Fund VI to acquire Lumos from EQT’s predecessor fund, EQT Infrastructure III. The arrangement is expected to close in the first half of 2025, subject to customary closing conditions and regulatory approvals. At closing, we expect to invest approximately $950 million in the joint venture to acquire a 50% equity interest and all existing Lumos fiber customers. The funds invested by us will be used to fund future fiber builds. In addition, pursuant to the definitive agreement, we expect to make an additional capital contribution of approximately $500 million in 2027 or 2028 under the existing business plan.

For more information regarding the Lumos joint venture, see Note 3 – Joint Ventures of the Notes to the Consolidated Financial Statements.

Acquisition of UScellular Wireless Operations

On May 24, 2024, we entered into a securities purchase agreement with UScellular pursuant to which, among other things, we will acquire substantially all of UScellular’s wireless operations and select spectrum assets for an aggregate purchase price of approximately $4.4 billion, payable in cash and the assumption of up to $2.0 billion of debt through an exchange offer to be made to certain UScellular debtholders prior to closing. To the extent any debtholders do not participate in the exchange, their bonds will continue as obligations of UScellular, and the cash portion of the purchase price will be correspondingly increased. The transaction is expected to close in mid-2025, subject to customary closing conditions and receipt of certain regulatory approvals.

Following the closing of the transaction, UScellular will retain ownership of its other spectrum, as well as its towers. Subject to the closing of the transaction, we will enter into a 15-year master license agreement to lease space on at least 2,100 towers being retained and to extend our tenancy term on approximately 600 towers where we are already leasing space from UScellular for 15 years post-closing. We estimate the incremental future minimum lease payments associated with the master license agreement will be $1.4 billion over 15 years post-closing.

Metronet Joint Venture

On July 18, 2024, we entered into a definitive agreement with KKR to establish a joint venture to acquire Metronet. This arrangement is expected to close in 2025, subject to customary closing conditions and regulatory approvals. At closing, we expect to invest approximately $4.9 billion in the joint venture to acquire a 50% equity interest and all existing residential fiber customers, as well as funding the joint venture. We do not anticipate making further capital contributions following the closing under the existing business plan.

For more information regarding the Metronet joint venture, see Note 3 – Joint Ventures of the Notes to the Consolidated Financial Statements.

Acquisition of Vistar Media Inc.

On December 20, 2024, we entered into an agreement and plan of merger for the acquisition of 100% of the outstanding capital stock of Vistar Media Inc., for a purchase price of approximately $625 million. The purchase price is subject to certain agreed-upon working capital and other adjustments. The acquisition is subject to certain customary closing conditions, including certain regulatory approvals, and is expected to close in the first quarter of 2025.

For more information regarding the acquisition of Vistar Media Inc., see Note 2 – Business Combinations of the Notes to the Consolidated Financial Statements.

Off-Balance Sheet Arrangements

We have arrangements, as amended from time to time, to sell certain EIP accounts receivable and service accounts receivable on a revolving basis as a source of liquidity. As of December 31, 2024, we derecognized net receivables of $1.6 billion upon sale through these arrangements.

For more information regarding these off-balance sheet arrangements, see Note 5 – Sales of Certain Receivables of the Notes to the Consolidated Financial Statements.

Future Sources and Uses of Liquidity

We may seek additional sources of liquidity, including through the issuance of additional debt, to continue to opportunistically acquire spectrum licenses or other long-lived assets in private party transactions, repurchase shares, pay dividends or for the refinancing of existing long-term debt on an opportunistic basis. Excluding liquidity that could be needed for acquisitions of businesses, spectrum and other long-lived assets, or for any potential stockholder returns, we expect our principal sources of funding to be sufficient to meet our anticipated liquidity needs for business operations for the next 12 months, as well as our longer-term liquidity needs. Our intended use of any such funds is for general corporate purposes, including for capital expenditures, spectrum purchases, opportunistic investments and acquisitions, redemption of debt, tower obligations, share repurchases, and dividend payments.

We determine future liquidity requirements for operations, capital expenditures, share repurchases and dividend payments based in large part upon projected financial and operating performance, and opportunities to acquire additional spectrum or repurchase shares. We regularly review and update these projections for changes in current and projected financial and operating results, general economic conditions, the competitive landscape and other factors. We have incurred, and will incur, substantial expenses to comply with the Government Commitments, and we have incurred all of the remaining restructuring and integration costs associated with the Merger, with the cash expenditures for the Merger-related costs extending beyond 2024. There are a number of additional risks and uncertainties that could cause our financial and operating results and capital requirements to differ materially from our projections, which could cause future liquidity to differ materially from our assessment.

The indentures, supplemental indentures and credit agreements governing our long-term debt to affiliates and third parties, excluding financing leases, contain covenants that, among other things, limit the ability of the Issuers or borrowers and the Guarantor Subsidiaries to incur more debt, create liens or other encumbrances, and merge, consolidate or sell, or otherwise dispose of, substantially all of their assets. We were in compliance with all restrictive debt covenants as of December 31, 2024.

Financing Lease Facilities

We have uncommitted financing lease facilities with certain third parties that provide us with the ability to enter into financing leases for network equipment and services. As of December 31, 2024, we have entered into $9.9 billion of financing leases under these financing lease facilities, of which $1.2 billion was executed during the year ended December 31, 2024. We expect to enter into up to a total of $1.2 billion in financing lease commitments during the year ending December 31, 2025.

Capital Expenditures

Our liquidity requirements for capital expenditures have been driven primarily by capital expenditures for spectrum licenses, the construction, expansion and upgrading of our network infrastructure, the integration of the networks, spectrum, technology, personnel and customer base of T-Mobile and Sprint, which is substantially complete, and investments in information technology platforms. We expect to maintain our investment in capital expenditures related to these efforts in 2025 compared to

2024, as we continue to build out our nationwide 5G network and our digital transformation. Future capital expenditure requirements will be primarily driven by the deployment of acquired spectrum licenses.

For more information regarding our spectrum licenses, see Note 7 – Goodwill, Spectrum License Transactions and Other Intangible Assets of the Notes to the Consolidated Financial Statements.

Stockholder Returns

On September 6, 2023, our Board of Directors authorized our 2023-2024 Stockholder Return Program of up to $19.0 billion that ran from October 1, 2023, through December 31, 2024. The 2023-2024 Stockholder Return Program consisted of repurchases of shares of our common stock and the payment of cash dividends.

During the year ended December 31, 2024, we repurchased 59,376,922 shares of our common stock at an average price per share of $187.07 for a total purchase price of $11.1 billion, all of which were purchased under the 2023-2024 Stockholder Return Program.

During the year ended December 31, 2024, we paid an aggregate of $3.3 billion, in cash dividends to our stockholders, which was presented within Net cash used in financing activities on our Consolidated Statements of Cash Flows.

On December 13, 2024, we announced that our Board of Directors authorized our 2025 Stockholder Return Program of up to $14.0 billion that will run through December 31, 2025. The 2025 Stockholder Return Program is expected to consist of additional repurchases of shares of our common stock and the payment of cash dividends. The declaration and payment of all dividends is subject to the discretion of our Board of Directors and will depend on financial and legal requirements and other considerations. The amount available under the 2025 Stockholder Return Program for share repurchases will be reduced by the amount of any cash dividends declared and paid by us.

The 2025 Stockholder Return Program is the next step consistent with the Company’s capital allocation framework outlined at its recent Capital Markets Day. As discussed at Capital Markets Day, the Company expects its business plan to support approximately $80.0 billion in investments and capital returns between September 18, 2024, and the end of 2027. The Company currently plans to allocate such funds as follows:

Up to $50.0 billion for share repurchases and cash dividends, which includes the 2025 Stockholder Return Program;
Approximately $19.5 billion in a discretionary and flexible envelope for potential activities, which may include de-levering, investments in our core business, strategic investments, and/or additional capital returns to stockholders beyond the $50.0 billion initial allocation; and
Approximately $10.5 billion to complete pending transactions. See Note 2 - Business Combinations, Note 3 - Joint Ventures and Note 7 – Goodwill, Spectrum License Transactions and Other Intangible Assets for additional information.

On November 21, 2024, our Board of Directors declared a cash dividend of $0.88 per share on our issued and outstanding common stock, which will be paid on March 13, 2025, to stockholders of record as of the close of business on February 28, 2025.

As of December 31, 2024, $1.0 billion for dividends payable is presented within Other current liabilities on our Consolidated Balance Sheets.

Subsequent to December 31, 2024, from January 1, 2025, through January 24, 2025, we repurchased 2,855,113 shares of our common stock at an average price per share of $216.03 for a total purchase price of $617 million under the 2025 Stockholder Return Program. As of January 24, 2025, we had up to $13.4 billion remaining under the 2025 Stockholder Return Program for repurchases of shares and quarterly dividends through December 31, 2025.

For additional information regarding the 2023-2024 Stockholder Return Program and the 2025 Stockholder Return Program, see Note 15 – Stockholder Return Programs of the Notes to the Consolidated Financial Statements.

See Note 2 – Business Combinations of the Notes to the Consolidated Financial Statements for further information.
(6)On April 24, 2024, we entered into a definitive agreement with Fund VI to establish a joint venture between us and Fund VI to acquire Lumos.

Table of Contents

Certain commitments and obligations are included in the table based on the year of required payment or an estimate of the year of payment. Other long-term liabilities have been omitted from the table above due to the uncertainty of the timing of payments, combined with the lack of historical trends to predict future payments.

The purchase obligations reflected in the table above are primarily commitments to purchase spectrum licenses, wireless devices, network services, equipment, software, marketing sponsorship agreements and other items in the ordinary course of business. These amounts do not represent our entire anticipated purchases in the future but represent only those items for which we are contractually committed. Where we are committed to make a minimum payment to the supplier regardless of whether we take delivery, we have included only that minimum payment as a purchase obligation. The acquisition of spectrum licenses is subject to regulatory approval and other customary closing conditions.

Related Party Transactions

We have related party transactions associated with DT, SoftBank or their respective affiliates in the ordinary course of business, including intercompany servicing and licensing.

As of January 24, 2025, DT and SoftBank held, directly or indirectly, approximately 51.5% and 7.5%, respectively, of the outstanding T-Mobile common stock, with the remaining approximately 41.0% of the outstanding T-Mobile common stock held by other stockholders. As a result of the Proxy, Lock-Up and ROFR Agreement, dated April 1, 2020, by and between DT and SoftBank, DT has voting control, as of January 24, 2025, over approximately 58.7% of the outstanding T-Mobile common stock.

Disclosure of Iranian Activities under Section 13(r) of the Exchange Act

Section 219 of the Iran Threat Reduction and the Syria Human Rights Act of 2012 added Section 13(r) to the Exchange Act. Section 13(r) requires an issuer to disclose in its annual or quarterly reports, as applicable, whether it or any of its affiliates knowingly engaged in certain activities, transactions or dealings relating to Iran or with designated natural persons or entities involved in terrorism or the proliferation of weapons of mass destruction. Disclosure is required even where the activities, transactions or dealings are conducted outside the U.S. by non-U.S. affiliates in compliance with applicable law, and whether or not the activities are sanctionable under U.S. law.

As of the date of this report, we are not aware of any activity, transaction or dealing by us or any of our affiliates for the year ended December 31, 2024, that requires disclosure in this report under Section 13(r) of the Exchange Act, except as set forth below with respect to affiliates that we do not control and that are our affiliates solely due to their common control with either DT or SoftBank. We have relied upon DT and SoftBank for information regarding their respective activities, transactions and dealings.

DT, through certain of its non-U.S. subsidiaries, is party to roaming and interconnect agreements with the following mobile and fixed line telecommunication providers in Iran, some of which are or may be government-controlled entities: Irancell Telecommunications Services Company, Telecommunication Kish Company, Mobile Telecommunication Company of Iran, and Telecommunication Infrastructure Company of Iran. In addition, during the year ended December 31, 2024, DT, through certain of its non-U.S. subsidiaries, provided basic telecommunications services to five customers in Germany identified on the Specially Designated Nationals and Blocked Persons List maintained by the U.S. Department of Treasury’s Office of Foreign Assets Control: Bank Melli, Europäisch-Iranische Handelsbank, CPG Engineering & Commercial Services GmbH, Golgohar Trade and Technology GmbH and International Trade and Industrial Technology ITRITEC GmbH. These services have been terminated or are in the process of being terminated. For the year ended December 31, 2024, gross revenues of all DT affiliates generated by roaming and interconnection traffic and telecommunications services with the Iranian parties identified herein were less than $0.1 million, and the estimated net profits were less than $0.1 million.

In addition, DT, through certain of its non-U.S. subsidiaries that operate a fixed-line network in their respective European home countries (in particular, Germany), provides telecommunications services in the ordinary course of business to the Embassy of Iran in those European countries. Gross revenues and net profits recorded from these activities for the year ended December 31, 2024, were less than $0.1 million. We understand that DT intends to continue these activities.

Separately, SoftBank, through one of its non-U.S. subsidiaries, provides roaming services in Iran through Irancell Telecommunications Services Company. During the year ended December 31, 2024, SoftBank had no gross revenues from such services, and no net profit was generated. We understand that the SoftBank subsidiary intends to continue such services. This subsidiary also provides telecommunications services in the ordinary course of business to accounts affiliated with the Embassy of Iran in Japan. During the year ended December 31, 2024, SoftBank estimates that gross revenues and net profit

generated by such services were both under $0.1 million. We understand that the SoftBank subsidiary is obligated under contract and intends to continue such services.

In addition, SoftBank, through one of its non-U.S. indirect subsidiaries, provides office supplies to the Embassy of Iran in Japan. SoftBank estimates that gross revenues and net profit generated by such services during the year ended December 31, 2024, were both under $0.1 million. We understand that the SoftBank subsidiary intends to continue such activities.

Critical Accounting Estimates

Our significant accounting policies are fundamental to understanding our results of operations and financial condition as they require that we use estimates and assumptions that may affect the value of our assets or liabilities and financial results. See Note 1 – Summary of Significant Accounting Policies of the Notes to the Consolidated Financial Statements for further information.

Two of these policies, discussed below, relate to critical estimates because they require management to make difficult, subjective and complex judgments about matters that are inherently uncertain and because it is likely that materially different amounts would be reported under different conditions or using different assumptions. Actual results could differ from those estimates.

Management and the Audit Committee of the Board of Directors have reviewed and approved the accounting policies associated with these critical estimates.

Depreciation

Our property and equipment balance represents a significant component of our consolidated assets. We record property and equipment at cost, and we generally depreciate property and equipment on a straight-line basis over the estimated useful life of the assets. If all other factors were to remain unchanged, we expect that a one-year increase in the useful lives of our in-service property and equipment would have resulted in a decrease of approximately $3.2 billion in our 2024 depreciation expense and that a one-year decrease in the useful life would have resulted in an increase of approximately $4.6 billion in our 2024 depreciation expense.

See Note 1 – Summary of Significant Accounting Policies and Note 6 – Property and Equipment of the Notes to the Consolidated Financial Statements for information regarding depreciation of assets, including management’s underlying estimates of useful lives.

Income Taxes

We account for uncertainty in income taxes recognized in the financial statements in accordance with the accounting guidance for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. We assess whether it is more likely than not that a tax position will be sustained upon examination based on the technical merits of the position and adjust the unrecognized tax benefits in light of changes in facts and circumstances, such as changes in tax law, interactions with taxing authorities and developments in case law.

The income tax laws of the jurisdictions in which we operate are complex and subject to different interpretations by management and the relevant government taxing authorities. In establishing a provision for income tax expense, we must make judgments about the application of these inherently complex tax laws. We must also make estimates about when in the future certain items will affect taxable income in the various tax jurisdictions. Our interpretations may be subjected to review during examination by taxing authorities and disputes may arise over the respective tax positions. We attempt to resolve these disputes during the tax examination and audit process and ultimately through the court system when applicable.

We monitor relevant tax authorities and revise our estimate of accrued income taxes due to changes in income tax laws and their interpretation by the courts and regulatory authorities on a quarterly basis. Revisions of our estimate of accrued income taxes also may result from our own income tax planning and from the resolution of income tax controversies. Such revisions in our estimates may be material to our Income tax expense for any given quarter.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

We are exposed to economic risks in the normal course of business, primarily from changes in interest rates, including changes in investment yields and changes in spreads due to credit risk and other factors. These risks, along with other business risks, impact our cost of capital. Our policy is to manage exposure related to fluctuations in interest rates in order to manage capital costs, control financial risks and maintain financial flexibility over the long term. We have established interest rate risk limits that are closely monitored by measuring interest rate sensitivities of our debt portfolio. As of December 31, 2024, we held €2.0 billion in EUR-denominated Senior Notes, which are subject to foreign currency exchange rate fluctuations. We have entered into cross-currency swap agreements that qualify and have been designated as fair value hedges of our EUR-denominated debt, mitigating our exposure to foreign currency transaction gains and losses. We do not foresee significant changes in the strategies used to manage market risk in the near future.

Certain potential sources of financing available to us, including our Revolving Credit Facility, bear interest that is indexed to a benchmark rate plus a fixed margin. As of December 31, 2024, we did not have outstanding balances under these facilities. See Note 9 – Debt of the Notes to the Consolidated Financial Statements for additional information.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of T-Mobile US, Inc.

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of T-Mobile US, Inc. and subsidiaries (the "Company") as of December 31, 2024 and 2023, the related consolidated statements of comprehensive income, stockholders' equity, and cash flows, for each of the three years in the period ended December 31, 2024, and the related notes (collectively referred to as the "consolidated financial statements"). We also have audited the Company’s internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2024 and 2023, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2024, in conformity with accounting principles generally accepted in the United States of America. Also, in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control — Integrated Framework (2013) issued by COSO.

Basis for Opinions

The Company’s management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the Management’s Annual Report on Internal Control over Financial Reporting included in Item 9A. Our responsibility is to express an opinion on the Company’s consolidated financial statements and an opinion on the Company’s internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures to respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
53

Index for Notes to the Consolidated Financial Statements
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current-period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Revenues – Refer to Notes 1 and 11 to the consolidated financial statements

Critical Audit Matter Description

The Company generates revenues from providing wireless communications services and selling devices and accessories to customers. The processing and recording of service revenues related to monthly wireless services billings is highly automated and is based on contractual terms with customers. Equipment revenues related to device and accessory sales are typically recognized at a point in time when control of the device or accessory is transferred to the customer or dealer. The Company’s service and equipment revenues consist of a significant volume of low-dollar transactions accumulated from multiple systems and databases.

Given the large volume of low-dollar service and equipment revenue transactions which are initiated, accumulated, and recorded in multiple systems and databases, auditing service and equipment revenues was complex and challenging due to the extent of audit effort required and the need for professionals with expertise in information technology (IT) to identify, evaluate, and test the Company’s systems, databases, automated controls, and system interface controls.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to the Company’s service and equipment revenue transactions included the following, among others:
With the assistance of our IT specialists, we:
Identified the relevant systems and databases used to process service and equipment revenue transactions and tested the relevant IT controls over each of those systems and databases.
Performed testing of automated business controls and system interface controls within service and equipment revenues.
We tested internal controls in the revenue accounting processes, including those in place to (a) establish revenue recognition accounting policies for promotional offers, (b) record revenue and the related promotional offers in accordance with the established accounting policies and (c) reconcile the various systems to the Company’s general ledger.
We created data visualizations to evaluate recorded service and equipment revenue and trends in the related subscriber data.
For a selection of wholesale service revenue and equipment revenue transactions, we compared the amounts recognized to contractual agreements or other source documents and tested the mathematical accuracy of the recorded revenue.
We developed an expectation of postpaid and prepaid service revenue amounts using historical service revenue and subscriber information and compared it to the recorded amount.
We tested the accuracy and completeness of the subscriber information used in our audit procedures by selecting a sample of the subscriber information and for those selections agreeing the selected subscriber information to supporting documentation.

months, using an EIP. EIP receivables are presented on our Consolidated Balance Sheets at their amortized cost basis (i.e., the receivables’ UPB as adjusted for any written-off amounts due to impairment and unamortized discounts), net of the allowance for credit losses. At the time of an installment sale, we impute a discount for interest if the term exceeds 12 months as there is no stated rate of interest on the receivables. The receivables are recorded at their present value, which is determined by discounting expected future cash payments at the imputed interest rate. This adjustment results in a discount or reduction in the transaction price of the contract with a customer, which is allocated to the performance obligations of the arrangement such as Service and Equipment revenues on our Consolidated Statements of Comprehensive Income. The imputed discount rate reflects a current market interest rate and includes a component for estimated credit risk underlying the EIP receivable, reflecting the

years; however, the FCC has granted license renewals routinely and at a nominal cost. The spectrum licenses acquired expire at various dates and we believe we will be able to meet all requirements necessary to secure renewal of our spectrum licenses at a nominal cost. Moreover, we determined that there are currently no legal, regulatory, contractual, competitive, economic or other factors that limit the useful lives of our spectrum licenses. The utility of radio frequency spectrum does not diminish while activated on our network nor does it otherwise deteriorate over time. Therefore, we determined the spectrum licenses should be treated as indefinite-lived intangible assets.

At times, we enter into agreements to sell or exchange spectrum licenses. Upon entering into a sale or exchange arrangement, if the transaction has been deemed to have commercial substance and the spectrum licenses meet the held for sale criteria, the licenses are classified as held for sale at their carrying value, as adjusted for any impairment recognized, included in Other current assets or Other assets on our Consolidated Balance Sheets until approval and completion of the sale or an exchange. Upon closing of the transaction, spectrum licenses acquired as part of an exchange of nonmonetary assets are recorded at fair value and the difference between the fair value of the spectrum licenses obtained, carrying value of the spectrum licenses transferred and cash paid, if any, is recognized as a gain or loss on disposal of spectrum licenses included in Selling, general and administrative expenses on our Consolidated Statements of Comprehensive Income. Our fair value estimates of spectrum licenses are based on information for which there is little or no observable market data. If the transaction lacks commercial substance or the fair value is not measurable, the acquired spectrum licenses are recorded at our carrying value of the spectrum assets transferred or exchanged.

We have lease agreements (the “Agreements”) with various educational and non-profit institutions that provide us with the right to use Federal Communications Commission (“FCC”) spectrum licenses (known as “Educational Broadband Services” or “EBS” spectrum) in the 2.5 GHz band. The Agreements are typically for terms of five to years with automatic renewal provisions, bringing the total term of the Agreements up to years. A majority of the Agreements include a right of first refusal to acquire, lease or otherwise use the license at the end of the automatic renewal periods.

Leased FCC spectrum licenses are recorded as executory contracts, and contractual lease payments are recognized on a straight-line basis over the remaining term of the arrangement, including renewals, and are presented in Cost of services on our Consolidated Statements of Comprehensive Income.

The spectrum licenses we hold plus the spectrum leases enhance the overall value of our spectrum licenses as the collective value is higher than the value of individual bands of spectrum within a specific geography. This value is derived from the ability to provide wireless service to customers across large geographic areas and maintain the same or similar wireless connectivity quality. This enhanced value from combining owned and leased spectrum licenses is referred to as an aggregation premium.

The aggregation premium is a component of the overall fair value of our owned FCC spectrum licenses.

 billion of euro (“EUR”) denominated debt. T-Mobile’s functional currency is the U.S. dollar (“USD”). Each period, we convert activity and balances in EUR into USD using average exchange rates for the period for income statement amounts and using end-of-period or spot exchange rates for assets and liabilities. We record transaction gains and losses resulting from the conversion of transaction currency to functional currency as a component of Other income (expense), net on our Consolidated Statements of Comprehensive Income.


. However, promotional EIP bill credits offered to a customer on an equipment sale that are paid over time and are contingent on the customer maintaining a service contract may result in an extended service contract based on whether a substantive penalty is deemed to exist.

Revenue is recorded net of costs paid to a third party for performance obligations where we facilitate an arrangement for the other party to transfer goods or services to our customer (i.e., when we are acting as an agent). For example, performance obligations relating to services provided by third-party content providers where we neither control a right to the content provider’s service nor control the underlying service itself are presented net.

Consideration payable to a customer is treated as a reduction of the total transaction price, unless the payment is in exchange for a distinct good or service, such as certain commissions paid to dealers, in which case the payment is treated as a purchase of that distinct good or service.

 million, $ million and $ million, respectively, of USF fees on a gross basis.

We have made an accounting policy election to exclude from the measurement of the transaction price all taxes assessed to the customer by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction and collected by us from a customer on behalf of the taxing agency (e.g., sales, use, value added, and some excise taxes).

Equipment Revenues

We generate equipment revenues from the sale of mobile communication devices and accessories. Equipment revenues related to device and accessory sales are typically recognized at a point in time when control of the device or accessory is transferred to the customer or dealer. We have elected to account for shipping and handling activities that occur after control of the related good transfers as fulfillment activities, as opposed to performance obligations. We estimate variable consideration (e.g., device returns or certain payments to indirect dealers) primarily based on historical experience. Equipment sales for which we determine it is not probable that we will collect substantially all of the transaction price are generally recorded as payments are received. Our assessment of collectibility considers contract terms such as down payments that reduce our exposure to credit risk.

We offer certain customers the option to pay for devices and accessories in installments using an EIP. This financing option is provided at a stated interest of and is typically over a -month period. We recognize as a reduction of the total transaction price the effects of a financing component in contracts via the imputation of interest when customers purchase their devices and accessories on an EIP, including those financing components that are not considered to be significant to the contract. However, we have elected the practical expedient of not recognizing the effects of a significant financing component for contracts where we expect, at contract inception, that the period between the transfer of a performance obligation to a customer and the customer’s payment for that performance obligation will be one year or less.

Imputed Interest on EIP Receivables

For EIP with a duration greater than one year, we record the effects of financing via the imputation of interest. This is performed on all such EIP receivables regardless as to whether or not the financing is considered to be significant. The imputation of interest results in a discount of the EIP receivable, thereby adjusting the transaction price of the contract with the customer, which is then allocated to the performance obligations of the arrangement.

Judgment is required to determine the imputed interest rate. For EIP sales, the imputed rate used to adjust the transaction price reflects current market interest rates, including the estimated credit risk of the underlying customers. Customer credit behavior is inherently uncertain. See “Receivables and Related Allowance for Credit Losses” above, for additional discussion on how we assess credit risk.

Contract Balances

Generally, our devices and service plans are available at standard prices, which are maintained on price lists and published on our website and/or within our retail stores.

For contracts that involve more than one product or service that are identified as separate performance obligations, the transaction price is allocated to the performance obligations based on their relative standalone selling prices. The standalone selling price is the price at which we would sell the good or service separately, on a standalone basis, to similar customers in similar circumstances.

A contract asset is recorded when revenue is recognized in advance of our right to receive consideration (i.e., we must perform additional services in order to receive consideration). Amounts are recorded as receivables when our right to consideration is unconditional.

When consideration is received, or we have an unconditional right to consideration in advance of delivery of goods or services, a contract liability is recorded. The transaction price can include non-refundable upfront fees, which are allocated to the identifiable performance obligations.

months.

For capitalized contract costs, determining the amortization period over which such costs are recognized as well as assessing the indicators of impairment requires judgment. Prepaid commissions are expensed as incurred as their estimated period of benefit does not extend beyond 12 months. Commissions paid upon device upgrade are not capitalized if the remaining customer contract is less than one year.

See Note 11 – Revenue from Contracts with Customers for further information.

Wireline Business

On September 6, 2022, Sprint Communications LLC, a Kansas limited liability company and wholly owned subsidiary of the Company (“Sprint Communications”), Sprint LLC, a Delaware limited liability company and wholly owned subsidiary of the Company, and Cogent Infrastructure, Inc., a Delaware corporation (the “Buyer”) and a wholly owned subsidiary of Cogent Communications Holdings, Inc., entered into a Membership Interest Purchase Agreement (the “Wireline Sale Agreement”), pursuant to which Cogent Infrastructure, Inc. agreed to acquire the U.S. long-haul fiber network and operations (including the non-U.S. extensions thereof) of Sprint Communications and its subsidiaries (the “Wireline Business”). Such transactions contemplated by the Wireline Sale Agreement are collectively referred to as the “Wireline Transaction.” On May 1, 2023, Cogent Infrastructure, Inc. and the Company completed the Wireline Transaction.

Under the terms of the Wireline Sale Agreement, the Company agreed to make payments pursuant to an IP transit services agreement totaling $ million, consisting of (i) $ million in equal monthly installments during the first year after the closing and (ii) $ million in equal monthly installments over the subsequent months.

The present value of the $ million liability for fees payable for IP transit services was recognized and treated as part of the consideration exchanged with the Buyer to complete the disposal transaction, as there is a remote likelihood we will use any more than a de minimis amount of the services under the IP transit services agreement. Therefore, we concluded the cash payment obligations under the IP transit services agreement were part of the consideration paid to the Buyer to facilitate the sale of the Wireline Business, and therefore, included in measuring the fair value less costs to sell of the Wireline Business disposal group. As of December 31, 2024 and 2023, $ million and $ million of the liability associated with the IP transit services agreement, including accrued interest, is presented within Other current liabilities, respectively, and $ million and $ million of this liability, including accrued interest, is presented within Other long-term liabilities, respectively, on our Consolidated Balance Sheets.

During the year ended December 31, 2022, we recognized a pre-tax loss of $ billion within (Gain) loss on disposal group held for sale and a non-cash expense of $ million within Impairment expense on our Consolidated Statements of Comprehensive Income related to the disposition of the Wireline Business.

 billion of our common stock through September 30, 2023 (the “2022 Stock Repurchase Program”). On September 6, 2023, our Board of Directors authorized a stockholder return program of up to $ billion through December 31, 2024 (the “2023-2024 Stockholder Return Program”). The 2023-2024 Stockholder Return Program consisted of additional repurchases of shares of our common stock and the payment of cash dividends. On December 13, 2024, we announced that our Board of Directors authorized our 2025 Stockholder Return Program of up to $ billion that will run through December 31, 2025 (“2025 Stockholder Return Program”). The 2025 Stockholder Return Program is expected to consist of additional repurchases of shares of our common stock and the payment of cash dividends. The amount available under the 2025 Stockholder Return Program for share repurchases will be reduced by the amount of any cash dividends declared and paid by us.

The cost of repurchased shares, including equity reacquisition costs and related taxes, is included in Treasury stock on our Consolidated Balance Sheets. We accrue the cost of repurchased shares and exclude such shares from the calculation of basic and diluted earnings per share, as of the trade date. We recognize a liability for share repurchases which have not settled and for which cash has not been paid in Other current liabilities on our Consolidated Balance Sheets. Cash payments to reacquire our shares, including equity reacquisition costs and related taxes, are included in Repurchases of common stock on our Consolidated Statements of Cash Flows.

% of the outstanding equity of Ka’ena Corporation and its subsidiaries, including, among others, Mint Mobile LLC (collectively, “Ka’ena”), for a maximum purchase price of $ billion to be paid out % in cash and % in shares of T-Mobile common stock (the “Ka’ena Acquisition”). On March 13, 2024, we entered into Amendment No. 1 to the Merger and Unit Purchase Agreement, which amended, among other things, certain mechanics of the payment of the purchase consideration for the Ka’ena Acquisition, which resulted in a nominal increase in the percentage of cash compared to shares of T-Mobile common stock to be paid out as part of the total purchase price.

Upon the completion of certain customary closing conditions, including the receipt of certain regulatory approvals, on May 1, 2024 (the “Acquisition Date”), we completed the Ka’ena Acquisition, and as a result, Ka’ena became a wholly owned subsidiary of T-Mobile. Concurrently and as agreed upon through the Merger and Unit Purchase Agreement, T-Mobile and Ka’ena entered into certain separate transactions, including the effective settlement of the preexisting wholesale arrangement between T-Mobile and Ka’ena and agreements with certain of the sellers to provide services to T-Mobile during the post-acquisition period.

Ka’ena is a provider of prepaid mobile services in the U.S. through its primary brands, Mint Mobile and Ultra Mobile, and also offers a selection of wireless devices, including handsets and other mobile communication devices. Prior to the Ka’ena Acquisition, Ka’ena was a wholesale partner of the Company for which we recognized service revenues within Wholesale and other service revenues on our Consolidated Statements of Comprehensive Income, and for which Ka’ena incurred related expenses for the use of our network. On the Acquisition Date, this relationship was effectively terminated, and the Company acquired Ka’ena’s prepaid customer relationships and began to recognize service revenues associated with these customers within Prepaid revenues and operating expenses primarily within Selling, general and administrative expenses on our Consolidated Statements of Comprehensive Income subsequent to the Acquisition Date. The Ka’ena Acquisition enhances the Company’s position as a leading prepaid wireless carrier by diversifying our brand identities, enhancing our distribution footprint and preserving the value of our relationship with Ka’ena through its acquisition, including the acquisition of its prepaid customer relationships.

The financial results of Ka’ena from the Acquisition Date through December 31, 2024, were not material to our Consolidated Statements of Comprehensive Income, nor were they material to our prior period consolidated results on a pro forma basis. Costs related to the Ka’ena Acquisition were not material to our Consolidated Statements of Comprehensive Income.

Consideration Transferred

In accordance with the terms of the Merger and Unit Purchase Agreement, the total purchase price is variable, dependent upon specified performance indicators of Ka’ena, and consists of an upfront payment on the Acquisition Date and an earnout payable on August 1, 2026.

On the Acquisition Date and in satisfaction of the upfront payment, we transferred $ million in cash and shares of T-Mobile common stock valued at $ million as determined based on its closing market price on April 30, 2024, for a total

Index for Notes to the Consolidated Financial Statements
 million. An additional amount of the upfront payment payable to certain sellers was deferred and may be paid through January 2026. As of the Acquisition Date, we recognized a liability of $ million for the fair value of this deferred amount, which is included in the fair value of consideration transferred in the Ka’ena Acquisition. Furthermore, a portion of the upfront payment made on the Acquisition Date was for the settlement of the preexisting wholesale relationship with Ka’ena and excluded from the fair value of consideration transferred in the Ka’ena Acquisition. The amount of the upfront payment was subject to customary adjustments and as a result of such adjustments, $ million of the upfront payment was returned to T-Mobile during the fourth quarter of 2024, which resulted in a commensurate increase in the maximum amount payable in satisfaction of the earnout.

Based on the amount of the adjusted upfront payment, up to an additional $ million in future cash and T-Mobile common stock is payable in satisfaction of the earnout, dependent upon Ka’ena’s achievement of specified performance indicators.

$ million of the potential earnout amount is payment for the acquired Ka’ena business, and we recognized a liability of $ million for the fair value of such contingent consideration. This liability is adjusted to fair value at each future reporting date until settled, with a corresponding offset recorded to Selling, general and administrative expenses on our Consolidated Statements of Comprehensive Income.
$ million of the potential earnout amount is payment for services to be provided to T-Mobile by certain of the sellers during the post-acquisition period, as well as the replacement of equity awards of certain Ka’ena employees. We recognize expenses as such services are provided during the post-acquisition period within Selling, general and administrative expenses on our Consolidated Statements of Comprehensive Income, with a corresponding offset to Other current liabilities and Other long-term liabilities on our Consolidated Balance Sheets.

Fair value of cash paid to Ka’ena stockholders related to the adjusted upfront payment 
Fair value of contingent consideration

Total fair value of consideration exchanged$ 

The fair value of contingent consideration related to the earnout was estimated using the income approach, a probability-weighted discounted cash flow model, whereby a Monte Carlo simulation method estimated the probability of different outcomes. This fair value measurement is based on significant inputs not observable in the market and, therefore, represents a Level 3 measurement as defined in ASC 820. The key assumptions in applying the income approach for the contingent consideration include forecasted Ka’ena financial information, primarily revenue, marketing costs and customer metrics, the probability of achieving the forecasted financial information and the discount rate.

As of December 31, 2024, $ million of liabilities for contingent consideration and $ million of liabilities for post-acquisition services were presented within Other long-term liabilities on our Consolidated Balance Sheets.

Fair Value of Assets Acquired and Liabilities Assumed

We have accounted for the Ka’ena Acquisition as a business combination. The identifiable assets acquired and liabilities assumed from Ka’ena were recorded at their provisionally assigned fair values as of the Acquisition Date and consolidated with those of T-Mobile. Assigning fair values to the assets acquired and liabilities assumed at the Acquisition Date requires the use of judgment regarding estimates and assumptions. For the provisionally assigned fair values of the assets acquired and liabilities assumed, we used the cost and income approaches.

Intangible Assets

Goodwill with a provisionally assigned value of $ million represents the excess of the consideration transferred over the fair values of assets acquired and liabilities assumed. The provisionally assigned goodwill recognized includes expected growth in customers and service revenues to be achieved from the operations of the combined company, the assembled workforce of Ka’ena and intangible assets that do not qualify for separate recognition. Of the total provisionally assigned amount of goodwill resulting from the Ka’ena Acquisition of $ million, the preliminary amount deductible for tax purposes is $ million. All of the goodwill acquired is allocated to the Wireless reporting unit.

Other intangible assets acquired primarily include $ million of customer relationships with an estimated weighted-average useful life of , $ million of tradenames with an estimated weighted-average useful life of and $ million of other intangible assets with an estimated weighted-average useful life of . The customer relationships are being amortized using the sum-of-the-years digits method over their estimated useful lives, and the tradenames are being amortized on a straight-line basis over their estimated useful lives.

The preliminary fair value of customer relationships was estimated using the income approach. This fair value measurement is based on significant inputs not observable in the market, and, therefore, represents a Level 3 measurement as defined in ASC 820. The key assumptions in applying the income approach include forecasted subscriber churn rates, revenue over an estimated period of time, the discount rate and estimated income taxes.

Acquisition of UScellular Wireless Operations

On May 24, 2024, we entered into a securities purchase agreement with United States Cellular Corporation (“UScellular”), Telephone and Data Systems, Inc., and USCC Wireless Holdings, LLC, pursuant to which, among other things, we will acquire substantially all of UScellular’s wireless operations and select AWS, PCS, 600 MHz, 700 MHz and other spectrum assets for an aggregate purchase price of approximately $ billion, payable in cash and the assumption of up to $ billion of debt through an exchange offer to be made to certain UScellular debtholders prior to closing. To the extent any debtholders do not participate in the exchange, their bonds will continue as obligations of UScellular, and the cash portion of the purchase price will be correspondingly increased. The transaction is expected to close in mid-2025, subject to customary closing conditions and receipt of certain regulatory approvals. Upon closing of the transaction, we expect to account for the UScellular transaction as a business combination and to consolidate the acquired operations.

Acquisition of Vistar Media Inc.

On December 20, 2024, we entered into an agreement and plan of merger for the acquisition of % of the outstanding capital stock of Vistar Media Inc., a provider of technology solutions for digital-out-of-home advertisements, for a purchase price of approximately $ million. The purchase price is subject to certain agreed-upon working capital and other adjustments. The acquisition is subject to certain customary closing conditions, including certain regulatory approvals, and is expected to close in the first quarter of 2025.

In addition, pursuant to the definitive agreement, we expect to make an additional capital contribution of approximately $ million in 2027 or 2028 under the existing business plan.

On July 18, 2024, we entered into a definitive agreement with KKR & Co. Inc. (“KKR”) to establish a joint venture to acquire Metronet Holdings, LLC and certain of its affiliates (collectively, “Metronet”), a fiber-to-the-home platform. This arrangement is expected to close in 2025, subject to customary closing conditions and regulatory approvals. At closing, we expect to invest approximately $ billion in the joint venture to acquire a % equity interest and all existing residential fiber customers, as well as funding the joint venture. We do not anticipate making further capital contributions following the closing under the existing business plan.

Upon closing of the transactions, we expect to account for the Lumos and Metronet joint ventures under the equity method of accounting and recognize service revenues for the acquired Lumos and Metronet fiber customers and wholesale costs paid to the joint ventures for network access within Cost of services on our Consolidated Statements of Comprehensive Income.

portfolio segments: accounts receivable and equipment installment plan receivables.

Accounts Receivable Portfolio Segment

Accounts receivable balances are predominately comprised of amounts currently due from customers (e.g., for wireless communications services), device insurance administrators, wholesale partners, other carriers and third-party retail channels.

We estimate credit losses associated with our accounts receivable portfolio segment using an expected credit loss model, which utilizes an aging schedule methodology based on historical information and is adjusted for asset-specific considerations, current economic conditions and reasonable and supportable forecasts.

customer classes of “Prime” and “Subprime.” Prime customer receivables are those with lower credit risk, and Subprime customer receivables are those with higher credit risk. Customers may be required to make a down payment on their equipment purchases if their assessed credit risk exceeds established underwriting thresholds. In addition, certain customers within the Subprime category may be required to pay a deposit.

To determine a customer’s credit profile and assist in determining their credit class, we use a proprietary credit scoring model that measures the credit quality of a customer leveraging several factors, such as credit bureau information and consumer credit risk scores, as well as service and device plan characteristics.

EIP receivables had a combined weighted-average effective interest rate of % and % as of December 31, 2024 and 2023, respectively.

Off-Balance-Sheet Credit Exposures

We do not have material off-balance-sheet credit exposures as of December 31, 2024. In connection with the sales of certain service accounts receivable and EIP receivables pursuant to the sale arrangements, we provide guarantees of credit performance (prior to November 1, 2024, this was deferred purchase price assets) included on our Consolidated Balance Sheets measured at fair value that are based on a discounted cash flow model using Level 3 inputs, including estimated customer default rates and credit worthiness, dilutions and recoveries.

 billion. Sales of EIP receivables occur daily and are settled on a monthly basis.

In connection with this EIP Sale Arrangement, we formed a wholly owned subsidiary, which qualifies as a bankruptcy remote entity (the “EIP BRE”). Pursuant to the EIP Sale Arrangement, selected receivables are transferred to the EIP BRE. The EIP BRE then sells the receivables to a non-consolidated and unaffiliated third-party entity over which we do not exercise any level of control, nor does the third-party entity qualify as a VIE.

Variable Interest Entity

We determined that the EIP BRE is a VIE, as its equity investment at risk lacks the obligation to absorb a certain portion of its expected losses. We have a variable interest in the EIP BRE and have determined that we are the primary beneficiary based on our ability to direct the activities that most significantly impact the EIP BRE’s economic performance. Those activities include selecting which receivables are transferred into the EIP BRE and sold in the EIP Sale Arrangement and funding of the EIP BRE. Additionally, our equity interest in the EIP BRE obligates us to absorb losses and gives us the right to receive benefits from the EIP BRE that could potentially be significant to the EIP BRE. Accordingly, we include the balances and results of operations of the EIP BRE in our consolidated financial statements.

 $ Other assets  Other current liabilities  Other long-term liabilities  

In addition, the EIP BRE is a separate legal entity with its own separate creditors who will be entitled, prior to any liquidation of the EIP BRE, to be satisfied prior to any value in the EIP BRE becoming available to us. Accordingly, the assets of the EIP BRE may not be used to settle our general obligations, and creditors of the EIP BRE have no recourse to our general credit.

Sales of Service Accounts Receivable

Overview of the Transaction

In 2014, we entered into an arrangement to sell certain service accounts receivable on a revolving basis (the “Service Receivable Sale Arrangement”). The maximum funding commitment of the Service Receivable Sale Arrangement is $ million, and the facility expires in February 2025. As of both December 31, 2024 and 2023, the Service Receivable Sale Arrangement provided funding of $ million. Sales of receivables occur daily and are settled on a monthly basis. The receivables consist of service charges currently due from customers and are short-term in nature.

In connection with the Service Receivable Sale Arrangement, we formed a wholly owned subsidiary, which qualifies as a bankruptcy remote entity, to sell service accounts receivable (the “Service BRE”).

Pursuant to the amended Service Receivable Sale Arrangement, selected receivables are transferred to the Service BRE. The Service BRE then sells the receivables to a non-consolidated and unaffiliated third-party entity over which we do not exercise any level of control and which does not qualify as a VIE.

Variable Interest Entity

We determined that the Service BRE is a VIE, as its equity investment at risk lacks the obligation to absorb a certain portion of expected losses. We have a variable interest in the Service BRE and have determined that we are the primary beneficiary based on our ability to direct the activities that most significantly impact the Service BRE’s economic performance. Those activities include selecting which receivables are transferred into the Service BRE and sold in the Service Receivable Sale Arrangement and funding the Service BRE. Additionally, our equity interest in the Service BRE obligates us to absorb losses and gives us the right to receive benefits from the Service BRE that could potentially be significant to the Service BRE. Accordingly, we include the balances and results of operations of the Service BRE in our consolidated financial statements.

 $ Other current liabilities  

In addition, the Service BRE is a separate legal entity with its own separate creditors who will be entitled, prior to any liquidation of the Service BRE, to be satisfied prior to any value in the Service BRE becoming available to us. Accordingly, the assets of the Service BRE may not be used to settle our general obligations, and creditors of the Service BRE have no recourse to our general credit.

Sales of Receivables

The transfers of service accounts receivable and EIP receivables to the non-consolidated entities are accounted for as sales of financial assets. Once identified for sale, the receivable is recorded at the lower of cost or fair value. Upon sale, we derecognize the net carrying amount of the receivables.

We recognized the cash proceeds received upon sale in Net cash provided by operating activities on our Consolidated Statements of Cash Flows.

On October 22, 2024, we executed an amendment to the EIP Sale Arrangement and an amendment to the Service Receivable Sale Arrangement (together, the “Pledge Amendments”). Prior to the effective date of the Pledge Amendments, the credit enhancement feature of each of the EIP Sale Arrangement and the Service Receivable Sale Arrangement was in the form of a deferred purchase price. Pursuant to the Pledge Amendments, effective on November 1, 2024, the credit enhancement feature of each arrangement is replaced by a recourse guarantee liability, which is collateralized by pledged but unsold receivables. On November 1, 2024, we re-recognized $ million of gross service accounts receivables and $ million of gross EIP receivables.

Prior to the effective date of the Pledge Amendments, cash proceeds related to beneficial interests in securitization transactions in the form of the deferred purchase price were presented within Net cash used in investing activities on our Consolidated Statements of Cash Flows. Following the effective date of the Pledge Amendments, all cash proceeds associated with sold receivables are recognized within Net cash provided by operating activities on our Consolidated Statements of Cash Flows.

The recourse guarantee, and prior to the effective date of the Pledge Amendments, the deferred purchase price, represents a financial instrument that is primarily tied to the creditworthiness of our customers. At inception, we elected to measure the recourse guarantee liabilities at fair value with changes in fair value included in Selling, general and administrative expenses on our Consolidated Statements of Comprehensive Income. The fair value of the recourse guarantee liabilities is determined based on a discounted cash flow model which uses primarily Level 3 inputs, including customer default rates. As of December 31, 2024, our recourse guarantee liabilities related to the sales of service receivables and EIP receivables was $ million, as collateralized by $ million of gross service receivables and $ million of gross EIP receivables pledged but unsold, which represent our maximum exposure under the recourse guarantee. As of December 31, 2023, our deferred purchase price assets related to the sales of service receivables and EIP receivables was $ million.

Goodwill Impairment Assessment

Certain non-financial assets, including goodwill and indefinite-lived intangible assets such as Spectrum licenses, are not required to be measured at fair value on a recurring basis and are reported at carrying value. However, these assets are required to be assessed for impairment when events or circumstances indicate that carrying value may not be recoverable, and at least annually for goodwill and indefinite-lived intangible assets. The nonrecurring measurements of the fair value of these assets, for which observable market information may be limited, are classified within Level 3 of the fair value hierarchy. In the event an impairment is required, the asset is adjusted to its estimated fair value using market-based assumptions, to the extent they are available, as well as other assumptions that may require significant judgment.

For our annual assessment of the wireless reporting unit, we employed a qualitative approach. The fair value of the wireless reporting unit was estimated using a market approach, which is based on market capitalization. In addition to performing an assessment under the market approach we also considered any events or change in circumstances that occurred, noting no indication that the fair value of the wireless reporting unit may be below its carrying amount at December 31, 2024.

Spectrum Auctions

In January 2022, the FCC announced that we were the winning bidder of licenses in Auction 110 (3.45 GHz spectrum) for an aggregate purchase price of $ billion.

In September 2022, the FCC announced that we were the winning bidder of licenses in Auction 108 (2.5 GHz spectrum) for an aggregate price of $ million. At inception of Auction 108 in June 2022, we deposited $ million. We paid the FCC the remaining $ million for the licenses won in the auction in September 2022. On February 29, 2024, the FCC issued to us the licenses won in Auction 108, and substantially all of these licenses were deployed in March 2024. The licenses are included in Spectrum licenses on our Consolidated Balance Sheets as of December 31, 2024.

Spectrum Exchange Transactions

During the year ended December 31, 2024, we recognized non-cash spectrum license acquisitions associated with the closing of certain spectrum exchange transactions of $ billion, including $ million associated with the closing of an agreement with a third party for the exchange of certain of our 39 GHz spectrum licenses for certain of their 24 GHz spectrum license on October 15, 2024.

During the year ended December 31, 2024, we recognized gains associated with the closing of certain spectrum exchange transactions of $ million, including a $ million gain associated with the closing of an agreement with a third party for the exchange of certain of our 39 GHz spectrum licenses for certain of their 24 GHz spectrum license on October 15, 2024, as a reduction to Selling, general and administrative expenses on our Consolidated Statements of Comprehensive Income. There were gains or losses associated with spectrum exchange transactions during the years ended December 31, 2023 and 2022.

License Purchase Agreements

DISH Network Corporation

On July 1, 2020, we and DISH Network Corporation (“DISH”) entered into a License Purchase Agreement (the “DISH License Purchase Agreement”) pursuant to which DISH agreed to purchase certain 800 MHz spectrum licenses for a total of approximately $ billion. On October 15, 2023, we and DISH entered into an amendment (the “LPA Amendment”) to the DISH License Purchase Agreement pursuant to which, among other things, the parties agreed that (1) DISH will pay us a $ million non-refundable extension fee (in lieu of the approximately $ million termination fee that had previously been agreed to), (2) the closing for the purchase of the spectrum licenses by DISH will occur no later than April 1, 2024, (3) if DISH has not purchased the spectrum licenses by such date for any reason (including failure to receive the required FCC approval prior to such date), then the DISH License Purchase Agreement will automatically terminate, and we will retain the $ million extension fee, (4) if DISH does purchase the spectrum by April 1, 2024, the $ million extension fee will be credited against the $ billion purchase price, and (5) we are permitted to commence auction of the spectrum prior to April 1, 2024 at our discretion (and subject to DISH’s purchase right). The LPA Amendment was approved by the Court and became effective on October 23, 2023. On October 25, 2023, we received a payment of $ million from DISH for the extension fee and recorded a corresponding liability within Other current liabilities on our Consolidated Balance Sheets.

DISH did not purchase the 800 MHz spectrum by April 1, 2024. As such, we recognized a gain for the $ million extension fee previously paid by DISH during the year ended December 31, 2024, within Selling, general and administrative expenses on our Consolidated Statements of Comprehensive Income and relieved the liability that was initially recorded upon receipt of the

 billion. The licenses will be acquired without any associated networks and are currently being utilized by us through exclusive leasing arrangements with the Sellers.

On March 30, 2023, we and the Sellers entered into Amended and Restated License Purchase Agreements pursuant to which we and the Sellers agreed to separate the transaction into tranches of licenses, with the closings on the acquisitions of certain licenses in Chicago, Dallas and New Orleans being deferred in order to potentially expedite the regulatory approval process for the remainder of the licenses. Subsequently, on August 25, 2023, we and the Sellers entered into Amendments No. 1 to the Amended and Restated License Purchase Agreements, which deferred the closings of certain additional licenses in Chicago and Dallas into the second closing tranche. Together, the licenses with closings deferred into the second closing tranche represent $ billion of the aggregate $ billion cash consideration. The licenses being acquired by us, and the total consideration being paid for the licenses, remain the same under the original License Purchase Agreements and subsequent amendments.

The FCC approved the purchase of the first tranche on December 29, 2023. The first tranche closed on June 24, 2024, and the associated payment of $ billion was made on August 5, 2024.

The FCC approved the purchase of the Dallas licenses included in the second tranche on October 22, 2024. The purchase of the Dallas licenses closed on December 6, 2024, and the associated payment of $ million was made on the same day.

We anticipate that the remaining deferred licenses from the second tranche of $ million will close in 2025.

The parties have agreed that each of the closings will occur within days after the receipt of the applicable required regulatory approvals, and payment of each portion of the aggregate $ billion purchase price will occur no later than days after the date of each respective closing.

Comcast Corporation

On September 12, 2023, we entered into a License Purchase Agreement with Comcast Corporation and its affiliate, Comcast OTR1, LLC (together with Comcast Corporation, “Comcast”), pursuant to which we will acquire spectrum in the 600 MHz band from Comcast in exchange for total cash consideration of between $ billion and $ billion, subject to an application for FCC approval. The licenses will be acquired without any associated networks. We anticipate the closing will occur in the first half of 2028.

The final purchase price will be determined, in the aggregate and on a per license basis, based on the set of licenses subject to the License Purchase Agreement at the time the parties make required transfer filings with the FCC. Prior to the time of such filings, Comcast has the right to remove any or all of a certain specified subset of the licenses, totaling $ billion (the “Optional Sale Licenses”), from the License Purchase Agreement. The removal of any Optional Sale Licenses would reduce the final purchase price by the assigned value of each such license, from the maximum purchase price of $ billion.

The licenses are subject to an exclusive leasing arrangement between us and Comcast, which were entered into contemporaneously with the License Purchase Agreement. If Comcast elects to remove an Optional Sale License from the License Purchase Agreement, the associated lease for such Optional Sale License will terminate, but no sooner than from the date of the License Purchase Agreement (with us having a minimum period of time after any such termination to cease transmitting on such license’s associated spectrum).

On January 13, 2025, we and Comcast entered into an amendment to the License Purchase Agreement pursuant to which we will acquire additional spectrum. Subsequent to the amendment, the total cash consideration for the transaction is between $ billion and $ billion.

 billion in Spectrum licenses on our Consolidated Balance Sheets. We maintain the right to terminate the License Purchase Agreement no later than February 7, 2025, as we did not receive written notice of committed financing as of December 9, 2024, from the Buyer at or above a certain target level of cash consideration. The transaction is subject to FCC approval. We do not expect the transaction to have a material impact on our Consolidated Statements of Comprehensive Income.

Impairment Assessment

For our assessment of Spectrum license impairment, we employed a qualitative approach. No events or change in circumstances have occurred that indicate the fair value of the Spectrum licenses may be below its carrying amount at December 31, 2024.

 billion to USD borrowings, with the same maturities of five, eight and years. The swaps qualify and have been designated as fair value hedges of our EUR-denominated debt, mitigating our exposure to foreign currency transaction gains and losses.

Accordingly, all changes in the fair value of the swaps will be initially recorded through Accumulated other comprehensive loss on our Consolidated Balance Sheets and reclassified to earnings in an amount that exactly offsets the periodic transaction gain or loss on remeasuring the debt, such that there will be no earnings volatility due to changes in foreign-currency exchange rates. Transaction gains or losses on remeasuring the EUR-denominated debt, as well as the offsetting swap amounts, are recorded within Other income (expense), net on our Consolidated Statements of Comprehensive Income.

Changes in the fair value of the swaps may be different from the current period transaction gain or loss on remeasurement of the debt, in which case the difference will remain in Accumulated other comprehensive loss on our Consolidated Balance Sheets. These differences generally represent credit or liquidity risk, referred to as a basis spread, and the time value of money (“excluded components”). The value of the excluded components is recognized in earnings using a systematic and rational method by accruing the current-period swap settlements into Interest expense, net, on our Consolidated Statements of Comprehensive Income. If an amount remains in Accumulated other comprehensive loss on our Consolidated Balance Sheets upon settlement of the derivative, those amounts will be reclassified to earnings at that time.

Recourse Guarantee Liabilities and Deferred Purchase Price Assets

In connection with the sales of certain service and EIP accounts receivable, we have recourse guarantee liabilities, and prior to the effective date of the Pledge Amendments, deferred purchase price assets, measured at fair value on a recurring basis that are based on a discounted cash flow model using unobservable Level 3 inputs, including estimated customer default rates and credit worthiness, dilutions and recoveries. See Note 5 – Sales of Certain Receivables for further information.

The carrying amount of our recourse guarantee liabilities was $ million as of December 31, 2024. The carrying amount of our deferred purchase price assets was $ million as of December 31, 2023. Both of which are included on our Consolidated Balance Sheets for the periods indicated.

Debt

The fair values of our Senior Notes and spectrum-backed Senior Secured Notes to third parties were determined based on quoted market prices in active markets. Accordingly, our Senior Notes and spectrum-backed Senior Secured Notes to third parties were classified as Level 1 within the fair value hierarchy. The fair value of our Senior Notes to affiliates was determined based on market interest rates of instruments with similar terms and maturities. Accordingly, our Senior Notes to affiliates were classified as Level 2 within the fair value hierarchy. The fair value of our Senior Notes to third parties (EUR-denominated) and asset-backed notes (“ABS Notes”) was primarily based on quoted prices in inactive markets for identical instruments and observable changes in market interest rates, both of which are Level 2 inputs. Accordingly, our Senior Notes to third parties (EUR-denominated) and ABS Notes were classified as Level 2 within the fair value hierarchy.

Although we have determined the estimated fair values using available market information and commonly accepted valuation methodologies, judgment was required in interpreting market data to develop fair value estimates for the Senior Notes to third parties (EUR-denominated), Senior Notes to affiliates and ABS Notes. The fair value estimates were based on information available as of December 31, 2024 and 2023. As such, our estimates are not necessarily indicative of the amount we could realize in a current market exchange.

Our effective interest rate, excluding the impact of derivatives and capitalized interest, was approximately % and % on weighted-average debt outstanding of $ billion and $ billion for the years ended December 31, 2024 and 2023, respectively. The weighted-average debt outstanding was calculated by applying an average of the monthly ending balances of total short-term and long-term debt to third parties and short-term and long-term debt to affiliates, net of unamortized premiums, discounts, debt issuance costs and consent fees.

Senior Notes

The Senior Notes are guaranteed on a senior unsecured basis by the Company and certain of our consolidated subsidiaries. They are redeemable at our discretion, in whole or in part, at any time. The redemption price is calculated by reference to the date on which such notes are redeemed and generally includes a premium that steps down gradually as the Senior Notes approach their par call date, on or after which they are redeemable at par. The amount of time by which the par call date precedes the maturity date of the respective series of Senior Notes varies from to .

We maintain a revolving credit facility (the “Revolving Credit Facility”) with an aggregate commitment amount of $ billion, including a letter of credit sub-facility of up to $ billion and a swingline loan sub-facility of up to $ million. As of December 31, 2024 and 2023, we did have an outstanding balance under the Revolving Credit Facility.

Asset-backed Notes

In connection with issuing the ABS Notes, we formed a wholly owned subsidiary, which qualifies as a bankruptcy remote entity (the “ABS BRE”), and a trust (the “ABS Trust” and together with the ABS BRE, the “ABS Entities”), in which the ABS BRE holds a residual interest. The ABS BRE’s residual interest in the ABS Trust represents the rights to all funds not needed to make required payments on the ABS Notes and other related payments and expenses.

Under the terms of the ABS Notes, our wholly owned subsidiary, T-Mobile Financial LLC (“FinCo”), and certain of our other wholly owned subsidiaries (collectively, the “Originators”) transfer EIP receivables to the ABS BRE, which in turn transfers such receivables to the ABS Trust, which issued the ABS Notes. The Class A senior ABS Notes have an expected weighted average life of approximately years. Under the terms of the transaction, there is a revolving period during which we may transfer additional receivables to the ABS Entities as collections on the receivables are received. The EIP receivables transferred to the ABS Entities and related assets, consisting primarily of restricted cash, will only be available for payment of the ABS Notes and expenses related thereto, payments to the Originators in respect of additional transfers of device payment plan agreement receivables, and other obligations arising from our ABS Notes transactions, and will not be available to pay our other obligations until the associated ABS Notes and related obligations are satisfied. The third-party investors in the Class A senior ABS Notes have legal recourse only to the assets of the ABS Trust securing the ABS Notes and do not have any recourse to T-Mobile with respect to the payment of principal and interest. The receivables transferred to the ABS Trust will only be available for payment of the ABS Notes and other obligations arising from the transaction and will not be available to pay any obligations or claims of T-Mobile’s creditors.

Under a parent support agreement, T-Mobile has agreed to guarantee the performance of the obligations of FinCo, which will continue to service the receivables, and the other T-Mobile entities participating in the transaction. However, T-Mobile does not guarantee any principal or interest on the ABS Notes or any payments on the underlying EIP receivables.

Cash collections on the EIP receivables are required at certain specified times to be placed into segregated accounts. Deposits to the segregated accounts are considered restricted cash and are included in Other current assets on our Consolidated Balance Sheets.

As of December 31, 2024, $ billion of our ABS Notes were secured in total by $ billion of gross EIP receivables and future collections on such receivables. Our ABS Notes and the assets securing this debt are included on our Consolidated Balance Sheets.

The net benefit associated with the Pension Plan is included in Other income (expense), net on our Consolidated Statements of Comprehensive Income.

Investments of the Pension Plan are measured at fair value on a recurring basis, which is determined using quoted market prices or estimated fair values. As of December 31, 2024, % of the investment portfolio was valued at quoted prices in active markets for identical assets, % was valued using quoted prices for similar assets in active or inactive markets, or other observable inputs, and % was valued using unobservable inputs that are supported by little or no market activity. As of December 31, 2023, % of the investment portfolio was valued at quoted prices in active markets for identical assets, % was valued using quoted prices for similar assets in active or inactive markets, or other observable inputs, and % was valued using unobservable inputs that are supported by little or no market activity, the majority of which used the net asset value per share (or its equivalent) as a practical expedient to measure the fair value.

The fair values of our Pension Plan assets and certain other postretirement benefit plan assets in aggregate were $ million and $ billion as of December 31, 2024 and 2023, respectively. Our accumulated benefit obligations in aggregate were $ million and $ billion as of December 31, 2024 and 2023, respectively. As a result, the plans were underfunded by approximately $ million and $ million as of December 31, 2024 and 2023, respectively, and were recorded in Other long-term liabilities on our Consolidated Balance Sheets. In determining our pension obligation for the years ended December 31, 2024 and 2023, we used a weighted-average discount rate of % and %, respectively.

During the years ended December 31, 2024 and 2023, we made contributions of $ million and $ million, respectively, to the benefit plans. We expect to make contributions to the Plan of $ million through the year ending December 31, 2025.

Future benefits expected to be paid are approximately $ million for the 12-month period ending December 31, 2025, $ million in total for both of the 12-month periods ending December 31, 2026 and 2027, $ million in total for both of the 12-month periods ending December 31, 2028 and 2029, and $ million in total thereafter.

Employee Retirement Savings Plan

We sponsor retirement savings plans for the majority of our employees under Section 401(k) of the Internal Revenue Code and similar plans. The plans allow employees to contribute a portion of their pre-tax and post-tax income in accordance with specified guidelines. The plans provide that we match a percentage of employee contributions up to certain limits. Employer matching contributions were $ million, $ million and $ million for the years ended December 31, 2024, 2023 and 2022, respectively.

As of December 31, 2024, we have tax effected federal net operating loss (“NOL”) carryforwards of $ billion, state NOL carryforwards of $ billion and foreign NOL carryforwards of $ million, expiring through 2044. Federal and certain state NOLs of $ billion generated in and after 2018 do not expire. As of December 31, 2024, our tax effected federal, state and foreign NOL carryforwards for financial reporting purposes were approximately $ million, $ million and $ million, respectively, less than our NOL carryforwards for federal, state and foreign income tax purposes, due to unrecognized tax benefits of the same amount. The unrecognized tax benefit amounts exclude offsetting tax effects of $ million in other jurisdictions.

As of December 31, 2024, we have research and development, corporate alternative minimum tax and other general business credit carryforwards with a combined value of $ million for federal income tax purposes, an immaterial amount of which begins to expire in 2039.

As of December 31, 2024, 2023 and 2022, our valuation allowance was $ million, $ million and $ million, respectively. The change from December 31, 2023 to December 31, 2024 primarily related to a reduction in the valuation allowance against federal and state deferred tax assets resulting from a change in expected utilization of accumulated capital losses. The change from December 31, 2022 to December 31, 2023 primarily related to a reduction in the valuation allowance against deferred tax assets in certain state jurisdictions resulting from expiration of the related state tax attributes.

We file income tax returns in the U.S. federal jurisdiction and in various state and foreign jurisdictions. We are currently under examination by various states. Management does not believe the resolution of any of the audits will result in a material change to our financial condition, results of operations or cash flows. The IRS has concluded audits of certain of our federal tax returns, most recently the 2020 tax year; however, NOL and other carryforwards for certain prior periods remain open for examination. U.S. federal, state and foreign examination for years prior to 2005 are generally closed.

These amounts are not reflective of our entire anticipated purchases under the related agreements but are determined based on the non-cancelable quantities or termination amounts to which we are contractually obligated.

On April 24, 2024, we entered into a definitive agreement with a fund operated by EQT, Fund VI, to establish a joint venture between us and Fund VI to acquire Lumos, a fiber-to-the-home platform, from EQT’s predecessor fund, EQT Infrastructure III. At closing, we expect to invest approximately $ million in the joint venture to acquire a % equity interest and all existing Lumos fiber customers. The funds invested by us will be used by the joint venture to fund future fiber builds. In addition, pursuant to the definitive agreement, we expect to make an additional capital contribution of approximately $ million in 2027 or 2028 under the existing business plan. The agreement remains subject to regulatory approval, and the estimated purchase price is excluded from our reported purchase commitments above. See Note 3 – Joint Ventures for additional details.

On May 24, 2024, we entered into a securities purchase agreement with UScellular, Telephone and Data Systems, Inc., and USCC Wireless Holdings, LLC, pursuant to which, among other things, we will acquire substantially all of UScellular’s wireless operations and select spectrum assets for an aggregate purchase price of approximately $ billion, payable in cash and the assumption of up to $ billion of debt through an exchange offer to be made to certain UScellular debtholders prior to closing. To the extent any debtholders do not participate in the exchange, their bonds will continue as obligations of UScellular, and the cash portion of the purchase price will be correspondingly increased. Following the closing of the transaction, we will enter into a master license agreement and estimate the incremental future minimum lease payments will be $ billion over years post-closing. The securities purchase agreement remains subject to regulatory approval. The estimated purchase price and incremental minimum lease payments are excluded from our reported purchase commitments above. See Note 2 – Business Combinations for additional details.

On December 20, 2024, we entered into an agreement and plan of merger for the acquisition of % of the outstanding capital stock of Vistar Media Inc., for a purchase price of approximately $ million. The agreement remains subject to certain regulatory approvals, and the estimated purchase price is excluded from our reported purchase commitments above. See Note 2 – Business Combinations for additional details.

Spectrum

We lease spectrum from various parties. These leases include service obligations to the lessors. Certain spectrum leases provide for minimum lease payments, additional charges, renewal options and escalation clauses. Leased spectrum agreements have varying expiration terms that generally extend through 2050. We expect that all renewal periods in our spectrum leases will be exercised by us. Certain spectrum leases also include purchase options and right-of-first refusal clauses in which we are provided the opportunity to exercise our purchase option if the lessor receives a purchase offer from a third party. The purchase of the leased spectrum is at our option and, therefore, the option price is not included in the commitments below.

Our spectrum lease and service credit commitments, including renewal periods, are approximately $ million for the 12-month period ending December 31, 2025, $ million in total for both of the 12-month periods ending December 31, 2026 and 2027, $ million in total for both of the 12-month periods ending December 31, 2028 and 2029, and $ billion in total thereafter.

On August 8, 2022, we entered into License Purchase Agreements to acquire spectrum in the 600 MHz band from Channel 51 License Co LLC and LB License Co, LLC in exchange for total cash consideration of $ billion. The first tranche closed on June 24, 2024, and the associated payment of $ billion was made on August 5, 2024. The purchase of the Dallas licenses closed on December 6, 2024, and the associated payment of $ million was made on the same day. The remaining deferred licenses from the second tranche of $ million remain subject to regulatory approval and are excluded from our reported purchase commitments above. See Note 7 – Goodwill, Spectrum License Transactions and Other Intangible Assets for additional details.

On September 12, 2023, we entered into a License Purchase Agreement with Comcast pursuant to which we will acquire spectrum in the 600 MHz band from Comcast in exchange for total cash consideration of between $ billion and $ billion, subject to an application for FCC approval. The licenses are subject to an exclusive leasing arrangement between us and Comcast entered into contemporaneously with the License Purchase Agreement. On January 13, 2025, we and Comcast entered into an amendment to the License Purchase Agreement pursuant to which we will acquire additional spectrum. Subsequent to the amendment, the total cash consideration for the transaction is between $ billion and $ billion. The agreement remains subject to an application for FCC approval and is excluded from our reported purchase commitments above. See Note 7 – Goodwill, Spectrum License Transactions and Other Intangible Assets for additional details.

Merger Commitments

In connection with the regulatory proceedings and approvals of the Merger pursuant to the Business Combination Agreement with Sprint and the other parties named therein (as amended, the “Business Combination Agreement”) and the other transactions contemplated by the Business Combination Agreement (collectively, the “Transactions”), we have commitments and other obligations to various state and federal agencies and certain nongovernmental organizations, including pursuant to the Consent Decree agreed to by us, DT, Sprint, SoftBank and DISH and entered by the U.S. District Court for the District of Columbia, and the FCC’s memorandum opinion and order approving our applications for approval of the Merger. These commitments and obligations include, among other things, extensive 5G network build-out commitments, obligations to deliver high-speed wireless services to the vast majority of Americans, including Americans residing in rural areas, and the marketing of an in-home broadband product where spectrum capacity is available. Other commitments relate to national security, pricing, service, employment and support of diversity initiatives. Many of the commitments specify time frames for compliance and reporting. Failure to fulfill our obligations and commitments in a timely manner could result in substantial fines, penalties, or other legal and administrative actions.

 million to fund claims submitted by class members, the legal fees of plaintiffs’ counsel and the costs of administering the settlement. As required under the terms of the settlement, we have spent an aggregate of $ million for data security and related technology in 2022 and 2023. The settlement provides a full release of all claims arising out of the August 2021 cyberattack by class members who did not opt out, against all defendants, including us, our subsidiaries and affiliates, and our directors and officers. The settlement contains no admission of liability, wrongdoing or responsibility by any of the defendants.

We anticipate that this settlement of the class action, along with other settlements of separate consumer claims that have been previously completed or are currently pending, will resolve substantially all of the claims brought to date by our current, former and prospective customers who were impacted by the 2021 cyberattack. In connection with the class action settlement and the separate settlements, we recorded a total pre-tax charge of approximately $ million in the second quarter of 2022. During the years ended December 31, 2024, 2023 and 2022, we recognized $ million, $ million and $ million, respectively, in reimbursements from insurance carriers for costs incurred related to the August 2021 cyberattack, which is included as a reduction to Selling, general and administrative expenses on our Consolidated Statements of Comprehensive Income.

In addition, in September 2022, a purported Company shareholder filed a derivative action in the Delaware Court of Chancery under the caption Harper v. Sievert et al., Case No. 2022-0819-SG, against our current directors and certain of our former directors, alleging claims for breach of fiduciary duty relating to the Company’s cybersecurity practices. We are also named as a nominal defendant in the lawsuit. On May 31, 2024, the court issued an opinion dismissing the plaintiff’s complaint in its entirety. The plaintiff has appealed that decision. We are unable at this time to predict the potential outcome of this lawsuit or whether we may be subject to further private litigation.

We have also received inquiries and contested legal proceedings from various government agencies, law enforcement and other governmental authorities related to the August 2021 cyberattack, which could result in substantial fines or penalties. We reached an agreement with the FCC, which was announced on September 30, 2024, to resolve one of those inquiries. We will continue to cooperate fully with the other agencies and regulators inquiring about the matter with an aim to resolve all of these matters. While we hope to resolve them in the near term, we cannot predict the timing or outcome of any of these matters or whether we may be subject to further regulatory inquiries, investigations, or enforcement actions.

In light of the inherent uncertainties involved in such matters, and based on the information currently available to us, in addition to the previously recorded pre-tax charge of approximately $ million noted above, we believe it is reasonably possible that we could incur additional losses associated with these proceedings and inquiries, and we will continue to evaluate information as it becomes known and will record an estimate for losses at the time or times when it is both probable that a loss has been incurred and the amount of the loss is reasonably estimable. Ongoing legal and other costs related to these proceedings and inquiries, as well as any potential future actions, may be substantial, and losses associated with any adverse judgments, settlements, penalties or other resolutions of such proceedings and inquiries could be material to our business, reputation, financial condition, cash flows and operating results.

On June 17, 2022, plaintiffs filed a putative antitrust class action complaint in the Northern District of Illinois, Dale et al. v. Deutsche Telekom AG, et al., Case No. 1:22-cv-03189, against DT, T-Mobile, and SoftBank, alleging that the Merger violated the antitrust laws and harmed competition in the U.S. retail cell service market. Plaintiffs seek injunctive relief and trebled monetary damages on behalf of a purported class of AT&T and Verizon customers whom plaintiffs allege paid artificially inflated prices due to the Merger. We are vigorously defending this lawsuit, but we are unable to predict the potential outcome.

We believe that the bad actor first retrieved data through the impacted API starting on or around November 25, 2022. We have notified individuals whose information was impacted consistent with state and federal requirements.

In connection with the January 2023 cyberattack, we became subject to consumer class actions and regulatory inquiries, to which we will continue to respond in due course and may incur significant expenses. However, we cannot predict the timing or outcome of any of these potential matters or whether we may be subject to additional legal proceedings, claims, regulatory inquiries, investigations, or enforcement actions. In addition, we are unable to predict the full impact of this incident on customer behavior in the future, including whether a change in our customers’ behavior could negatively impact our results of operations on an ongoing basis, although we presently do not expect that it will have a material effect on our operations.

Item 9A. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) designed to ensure information required to be disclosed in our reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Our disclosure controls are also designed to ensure that information required to be disclosed in the reports we file or submit under the Exchange Act is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure.

Under the supervision and with the participation of our management, including our Chief Executive Officer and our Chief Financial Officer, we carried out an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of the end of the period covered by this Form 10-K.

The certifications required by Section 302 of the Sarbanes-Oxley Act of 2002 are filed as exhibits 31.1 and 31.2, respectively, to this Form 10-K.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting, as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act, during our most recently completed fiscal quarter that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. We are currently preparing to implement a new global enterprise resource planning (“ERP”) system, which will replace many of our operating and financial systems. The ERP system is designed to accurately maintain our financial records, support integrated billing, supply chain and other operational functionality, facilitate data analysis and accelerate information reporting to our management team related to the operation of the business. The implementation is expected to occur in phases over the next several years.

As the phased implementation of the new ERP system continues, we could have changes to our processes and procedures which, in turn, could result in changes to our internal control over financial reporting. As such changes occur, we will evaluate quarterly whether such changes materially affect our internal control over financial reporting.

Management’s Annual Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of our financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. Internal control over financial reporting includes maintaining records that in reasonable detail accurately and fairly reflect our transactions, providing reasonable assurance that transactions are recorded as necessary for preparation of our financial statements in accordance with generally accepted accounting principles, providing reasonable assurance that receipts and expenditures are made in accordance with management authorization, and providing reasonable assurance that unauthorized acquisition, use or disposition of company assets that could have a material effect on our financial statements would be prevented or detected on a timely basis. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with policies and procedures may deteriorate.

Management conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework and criteria established in Internal Control – Integrated Framework (2013), issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this evaluation, management concluded that our internal control over financial reporting was effective as of December 31, 2024.

The effectiveness of our internal control over financial reporting as of December 31, 2024 has been audited by Deloitte & Touche LLP, an independent registered public accounting firm, as stated in their report herein.
