publicly release the results of any revision to these forward-looking statements, except as required by law. Additionally, we
may provide information that is not necessarily material for SEC reporting purposes but that is informed by various ESG
standards and frameworks (including standards for the measurement of underlying data), internal controls, and assumptions or
third-party information that are still evolving and subject to change. Our disclosures based on any standards may change due to
revisions in framework requirements, availability of information, changes in our business or applicable governmental policies,

PART I.

Item 1. Business

Business Overview and Strategy

Un-carrier Strategy

We are America’s supercharged Un-carrier. Through our Un-carrier strategy, we have disrupted the wireless communications
services industry by actively engaging with and listening to our customers and focusing on eliminating their existing pain
points. 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 customer experience focus,
consistently leading the wireless industry in customer care by delivering award-winning customer experience with our “Team
of Experts,” which drives our record-high customer satisfaction levels while enabling operational efficiencies.

With America’s largest, fastest, most reliable and most awarded 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 “layer cake” of spectrum provides an unmatched 5G 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). Our layer cake 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.

Our Operations

As of December 31, 2022, we provide wireless communications services to 113.6 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 and Metro by T-Mobile, through our owned and operated retail stores, as well
as through our websites (www.t-mobile.com and www.metrobyt-mobile.com), T-Mobile app, 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 mobile 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 Magenta Max, which allows customers to subscribe for wireless communications
services separately from the purchase of a device. This plan includes unlimited talk, text and data on our network, 5G access at
no extra cost, scam protection features and more. We also offer an Essentials rate plan for customers who want the basics at a
lower price point, as well as specific rate plans to qualifying customers, including Business, Military and Veterans, First
Responder, and Unlimited 55+.

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”). For certain existing
customers, devices are leased over an initial period of up to 18 months and may be upgraded when eligibility requirements are
met.

5

In addition to our mobile wireless communications services, we offer High Speed Internet, which is a fixed wireless product
that utilizes the excess capacity of our nationwide 5G network. Our fixed wireless product is available to millions of domestic
households, providing an alternative to traditional landline internet service providers and expanding access to many people who
have historically had only one choice or no access to traditional home broadband. 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, advertising and wireline communication services to domestic and international customers. In
September 2022, we entered into an agreement for the sale of the Wireline Business. See Note 16 – Wireline for additional
information.

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, tablets, wearables, DIGITS and other connected devices; and

Prepaid customers generally pay for wireless communications services, including High Speed Internet, in advance. Our
prepaid customers include customers of T-Mobile and Metro by T-Mobile.

Our customer base includes consumers as well as business customers, who are provided services under the T-Mobile for
Business brand.

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 2022, our service revenues generated by providing wireless
communications services by customer category were:

•

•

•

75% Postpaid customers;

16% Prepaid customers; and

9% Wholesale and other services.

Substantially all of our revenues for the years ended December 31, 2022, 2021 and 2020, were earned in the United States,
including Puerto Rico and the U.S. Virgin Islands.

Network Strategy

Utilizing our multi-layer 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 reliable and most awarded 5G network.

The Merger greatly enhanced our spectrum position. Integration of the spectrum and network assets acquired in the Merger is
expected to continue through 2023. Our integration strategy includes deploying the acquired spectrum on the combined network
assets to supplement capacity, migrating Sprint customers to our network and optimizing the combined assets by
decommissioning redundant sites. As of December 31, 2022, we have decommissioned substantially all targeted Sprint macro
sites. As a result of the Merger, we have achieved, and expect to continue to achieve, significant synergies and cost reductions
by eliminating redundancies within our network, as well as through other business processes and operations.

6

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, or expected to control based on previously announced auction results, an average of 388 MHz of
combined low- and mid-band spectrum nationwide as of December 31, 2022. This spectrum is comprised of:

•

•

•

•

•

•

•

•

An average of 38 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 40 MHz in the 1700 MHz AWS band;

An average of 66 MHz in the 1900 MHz PCS band;

An average of 181 MHz in the 2.5 GHz band;

An average of 12 MHz in the 3.45 GHz band; and

An average of 27 MHz in the C-band.

• We controlled an average of 1,157 GHz of combined mmWave spectrum licenses.

•

•

•

In January 2022, the FCC announced that we were the winning bidder of 199 licenses in Auction 110 (mid-band
spectrum) for an aggregate purchase price of $2.9 billion. On May 4, 2022, the FCC issued to us the licenses won in
Auction 110.

In August 2022, we entered into license purchase agreements pursuant to which we will acquire spectrum in the 600
MHz band in exchange for total cash consideration of $3.5 billion. See Note 6 – Goodwill, Spectrum License
Transactions and Other Intangible Assets for additional details.

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. The timing of when the licenses will be issued will be determined by
the FCC after all post-auction procedures have been completed.

• We plan to evaluate future spectrum purchases in future auctions and in the secondary market to further augment our

current spectrum position.

•

As of December 31, 2022, we had equipment deployed on approximately 79,000 macro cell sites and 41,000 small
cell/distributed antenna system sites across our network.

5G Leadership

Our 5G network is America’s largest, fastest, most reliable and most awarded:

•

•

As of December 31, 2022, our Ultra Capacity 5G utilizing mid-band and mmWave spectrum covers 263 million
people.

As of December 31, 2022, our total 5G coverage, including low-band spectrum, covers 325 million people, reaching
98% of Americans.

Competition

The wireless communications services industry is highly 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 competitors include other
national carriers, such as AT&T Inc. (“AT&T”) and Verizon Communications, Inc. (“Verizon”). In addition, our competitors
include numerous smaller and regional carriers, MVNOs, including Comcast Corporation, Charter Communications, Inc.,
Altice USA, Inc. and DISH, 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.
Competitive factors within the wireless communications services industry 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 aggressive pricing or offer bundled services as a
potential source of differentiation.

Human Capital

Employees

As of December 31, 2022, we employed approximately 71,000 full-time and part-time employees, including network, retail,
administrative and customer support functions.

Attraction and Retention

We employ a highly skilled workforce within a broad range of functions. Substantially all of our employees are located
throughout the United States, including Puerto Rico, to serve our nationwide network and retail operations. Our headquarters
are located in Bellevue, Washington, and Overland Park, Kansas.

We attract and retain our workforce through a dynamic and inclusive culture and by providing a comprehensive set of benefits,
including:

•

•

•
•

•

•

•

•

•

•

Competitive medical, dental and vision benefits;

Family-building benefits designed to meet the diverse needs of our employees, including IVF and IUI, adoption and
surrogacy benefits;

Annual stock grants to all full-time and part-time employees and a discounted Employee Stock Purchase Program;
A 401(k) Savings Plan;

Nationwide minimum pay of at least $20 per hour to all full-time and part-time employees;

LiveMagenta: a custom-branded program for employee engagement and well-being, including free access to life
coaches, financial coaches and tools for healthy living;

Access to personal health advocates offering independent guidance;

A generous paid time off program, including paid family leave;

Tuition assistance for all full-time and part-time employees, including full tuition partnerships with multiple schools;
and

A matching program for employee donations and volunteering.

Training and Development

Career growth and development is foundational to T-Mobile’s culture and success. We want to deliver the best experiences
from the best teams, and one way we do that is by offering an array of development programs and resources to build diverse
talent and empower our people to succeed through every step of their career. It is all easily accessible on our Magenta
University site, which is our one-stop shop for all things career development and learning. The online learning portal is
designed to 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 diversity, equity and inclusion (“DE&I”) - Promote inclusive habits and behaviors, enhance belonging and
connectedness, and advocate for equitable opportunities.

Diversity, Equity and Inclusion

DE&I have always been a part of the Un-carrier culture, and we are committed to having DE&I touch every aspect of our
future. Our Equity in Action Plan is a five-year plan that spans the values we live by, how we invest in and provide
opportunities for our employees, how we select the suppliers we do business with and how we advocate for our communities.

8

For our employees, we have established six DE&I Employee Resource Groups and four sub-affinity groups that have helped us
establish and maintain a culture of inclusion. Currently, we have over 45 DE&I chapters across the nation that help spearhead
volunteer opportunities, events and meaningful conversation with employees at a local level. Our DE&I Employee Resource
Groups include the following:

•

Accessibility Community at T-Mobile;

• Multicultural Alliance;

•

•

•

Asia Pacific & Allies Network;

Black Empowerment Network;

Indigenous Peoples Network;

• Magenta Latinx Network;

• Multigenerational Network;

•

•

Pride;

Veterans & Allies Network; and

• Women & Allies Network.

As part of T-Mobile’s Equity In Action Plan and Promises, we have established an External Diversity and Inclusion Council in
connection with our civil rights memorandum of understanding. The council includes civil rights leaders representing a wide
range of underrepresented communities. Together with T-Mobile, the council will help identify ways to improve our efforts in
focus areas such as corporate governance, workforce recruitment and retention, procurement, entrepreneurship, philanthropy
and community investment. Since April 2020, we have achieved a significant portion of the Equity In Action Promises.

As DE&I are instrumental to our culture and values, we are also on a mission to create fair and equitable opportunities for all
suppliers, including veteran-owned, disability-owned, woman-owned, minority-owned, LGBT-owned and small and
disadvantaged businesses. We have implemented a Supplier Diversity Category Management Strategy for our network
technology procurement organization to help identify opportunities and develop actionable targets for progress on this topic.

Environmental Sustainability

Reducing Carbon Footprint

We are working to reduce the impact of our operations on the climate by setting carbon reduction goals that are aligned with
science and investing in renewable energy. We are reducing our carbon footprint through several initiatives, including:

•

•

•

•

Setting a science-based net-zero target for 2040 that includes Scope 1, 2 and 3 emissions;

Investing in renewable energy, as evidenced by our RE100 pledge, a global initiative that unites businesses committed
to 100% renewable electricity. We first met this goal in 2021 and then again in 2022 by matching our electricity usage
with renewable energy credits acquired through a variety of sources, including through our engagement in Virtual
Power Purchasing Agreements and a Green Direct tariff agreement with nine clean energy providers for expected
annual provision of approximately 3.5 million megawatt hours of renewable electricity;

Continuously testing and evaluating new, efficient equipment for our facilities, including switch stations, cell sites,
retail stores and customer experience centers to reduce energy consumption; and

Promoting the circular economy through our device reuse and recycle program, which collects millions of devices for
reuse, resale, and recycling annually.

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 full 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.

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, disabilities access, privacy and cybersecurity, 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. A change in these policies could affect spectrum resources and competition among us and other
carriers.

Congress and the FCC have imposed limitations on foreign ownership of CMRS licensees that exceed 20% direct ownership or
25% indirect ownership through an entity controlling the licensee. The FCC has ruled that higher levels of indirect foreign
ownership, even up to 100%, are presumptively consistent with the public interest, but must be reviewed and approved.
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 up to 95% of their capacity 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. On April 27, 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

10

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

In addition, 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 have 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 are inconsistent with the FCC’s federal deregulatory approach. 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 RIF Order and be preempted; court challenges to some state enactments are pending.

While most states pursuing net neutrality legislation are largely seeking to codify the repealed federal rules, there are
differences in some states, notably California, which has passed separate privacy and net neutrality legislation, Colorado,
Connecticut, Utah and Virginia, which have passed privacy laws; and New York, which 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. State authority over wireless broadband services will remain unsettled until final action
by the courts 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 adversely affected by any of these risks.

Risks Related to Our Business and the Wireless Industry

Competition, industry consolidation, and changes in the market for wireless communications services and other forms
of connectivity could negatively affect our ability to attract and retain customers and adversely affect our business,
financial condition and operating results.

We have multiple competitors that possess either more or different access to wireless assets, and yet we compete for customers
based principally on service/device offerings, price, network coverage, speed and quality, and customer service. We expect the
wireless industry’s customer growth rate to moderate over time in comparison with historical growth rates, leading to ongoing
competition for customers. We also expect that our customers’ appetite for data services will place increasing demands on
wireless service providers. This competition and increasing demands for data services will continue to put pressure on pricing
and margins as companies, including us, compete for a relatively fixed pool of customers with an ever-expanding variety of

11

products and services. Our ability to compete will depend upon, among other things, continued absolute and relative
improvement in network quality, capacity and customer service, effective marketing and selling of products and services,
innovation, and attractive pricing, all of which will involve significant expenses.

We face increased competition from other service providers in the connectivity sector from within and outside of the wireless
industry, including from cable, fiber and satellite providers, as industry sectors converge. Cable companies such as Comcast,
Charter, and Altice are diversifying outside cable, voice and broadband services to also offer wireless services. Fiber companies
such as Lumen Technologies and Windstream have announced plans for fiber buildouts, often supported by government
funding. We expect DISH, which has already acquired several MVNOs, to build a wireless network and offer competitive
postpaid and prepaid wireless service plans. Verizon and AT&T have refocused on connectivity services, including fiber builds
and deployment of next generation wireless technology, and we expect both companies to increase competitive pressure,
including by expanding partnerships and offerings. These factors could make it more difficult for us to continue to attract and
retain customers, by adversely affecting our competitive position and ability to grow, including affecting our fixed wireless
High Speed Internet growth plans, which could have a material adverse effect on our business, financial condition, and
operating results.

We have seen, and continue to expect, additional joint ventures, mergers, acquisitions, and strategic alliances in the converged
connectivity sector, which could result in larger competitors competing for a limited number of customers. Further
consolidation could negatively impact our businesses, including wholesale. For example, we have experienced and will
continue to experience declining revenues from our wholesale business as Verizon migrates legacy TracFone customers off the
T-Mobile network and DISH services more of its Boost Mobile customers with their standalone network. Our competitors may
also enter into exclusive handset, device, or content arrangements, execute pervasive advertising and marketing campaigns, or
otherwise improve their cost position relative to ours, making it more difficult for us to compete and negatively impacting our
business. In addition, refusal of our competitors and partners to provide critical access to resources and inputs, such as roaming
and/or backhaul services to us, on reasonable terms could negatively impact our business.

We have experienced criminal cyberattacks and could in the future be further harmed by disruption, data loss or other
security breaches, whether directly or indirectly through third parties.

Our business involves the receipt, storage, and transmission of confidential information about our customers, such as sensitive
personal, account and payment card 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”). We are subject to persistent cyberattacks and threats to our networks,
systems, and supply chain from a variety of bad actors, many of whom attempt to gain access to and compromise Confidential
Information by exploiting bugs, errors, misconfigurations or other vulnerabilities in our networks and other systems (including
purchased and third-party systems) or by engaging in credential harvesting or social engineering. In some cases, these bad
actors may obtain unauthorized access to Confidential Information utilizing credentials taken from our customers, employees,
or third parties. Other bad actors aim to cause serious operational disruptions to our business or networks through other means,
such as through ransomware or distributed denial of services attacks.

Cyberattacks against companies like ours have increased in frequency and potential harm over time, and the methods used to
gain unauthorized access constantly evolve, making it increasingly difficult to anticipate, prevent, and/or detect incidents
successfully in every instance. They are perpetrated by a variety of groups and persons, including state-sponsored parties,
malicious actors, employees, contractors, or other unrelated third parties. Some of these persons reside in jurisdictions where
law enforcement measures to address such attacks are ineffective or unavailable, and such attacks may even be perpetrated by
or at the behest of foreign governments.

In addition, we routinely provide certain Confidential Information to third-party providers whose products and services are used
in our business operations, including as part of our IT systems, such as cloud services. These third-party providers have
experienced in the past, and will continue to experience in the future, cyberattacks that involve attempts to obtain unauthorized
access to our Confidential Information and/or to create operational disruptions that could adversely affect our business, and
these providers also face other security challenges common to all parties that collect and process information.

In August 2021, we disclosed that our systems were subject to a criminal cyberattack that compromised certain data of millions
of our current customers, former customers, and prospective customers, including, in some instances, social security numbers,
names, addresses, dates of birth and driver’s license/identification numbers. With the assistance of outside cybersecurity
experts, we located and closed the unauthorized access to our systems and identified current, former, and prospective customers
whose information was impacted and notified them, consistent with state and federal requirements. We have incurred certain
cyberattack-related expenses, including costs to remediate the attack, provide additional customer support and enhance

12

customer protection, and expect to incur additional expense in future periods resulting from the attack. For more information,
see “Recent Cyberattacks” in the Overview section of our Management’s Discussion and Analysis of Financial Condition and
Results of Operations. As a result of the August 2021 cyberattack, we are subject to numerous claims, lawsuits and regulatory
inquiries, the ongoing costs of which may be material, and we may be subject to further regulatory inquiries and private
litigation. For more information, see “– Contingencies and Litigation – Litigation and Regulatory Matters” in Note 19 –
Commitments and Contingencies of the Notes to the Consolidated Financial Statements.

In January 2023, we disclosed that a bad actor was obtaining data through a single Application Programming Interface (“API”)
without authorization. Based on our investigation to date, the impacted API is only able to provide a limited set of customer
account data, including name, billing address, email, phone number, date of birth, T-Mobile account number and information
such as the number of lines on the account and plan features. The result from our investigation to date indicates that the bad
actor(s) obtained data from this API for approximately 37 million current postpaid and prepaid customer accounts, though many
of these accounts did not include the full data set. We believe that the bad actor first retrieved data through the impacted API
starting on or around November 25, 2022. We continue to investigate the incident and have notified individuals whose
information was impacted consistent with state and federal requirements.

As a result of the August 2021 cyberattack and the January 2023 cyberattack, we may incur significant costs or experience
other material financial impacts, which may not be covered by, or may exceed the coverage limits of, our cyber liability
insurance, and such costs and impacts may have a material adverse effect on our business, reputation, financial condition, cash
flows and operating results.

In addition to the recent cyberattacks, we have experienced other unrelated immaterial incidents involving unauthorized access
to certain Confidential Information. Typically, these incidents have involved attempts to commit fraud by taking control of a
customer’s phone line, often by using compromised credentials. In other cases, the incidents have involved unauthorized access
to certain of our customers’ private information, including credit card information, financial data, social security numbers or
passwords, and to certain of our intellectual property.

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. 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. 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 know or assess the effectiveness of all of our providers’ systems
and controls at all times. We cannot provide any assurances that actions taken by us, or our third-party providers, 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. 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 are unable to take advantage of technological developments on a timely basis, we may experience a decline in
demand for our services or face challenges in implementing or evolving our business strategy.

Significant technological changes continue to impact our industry. In order to grow and remain competitive, we will need to
adapt to changes in available technology, continually invest in our network, increase network capacity, enhance our existing
offerings, and introduce new offerings to meet our current and potential customers’ changing service demands. Enhancing our
network, including the ongoing deployment of our 5G network, is subject to risks related to equipment changes and the
migration of customers from older technologies. Negative public perception of, and regulations regarding, the perceived health
risks relating to 5G networks could undermine market acceptance of our 5G services. Adopting new and sophisticated
technologies may result in implementation issues, such as scheduling and supplier delays, unexpected or increased costs,
technological constraints, regulatory permitting issues, customer dissatisfaction, and other issues that could cause delays in
launching new technological capabilities, which in turn could result in significant costs or reduce the anticipated benefits of the
upgrades. If our new services fail to retain or gain acceptance in the marketplace or if costs associated with these services are
higher than anticipated, this could have a material adverse effect on our business, brand, financial condition, and operating
results.

13

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 qualified personnel, or maintain our corporate culture.

The market for highly skilled workers and leaders is extremely competitive. We believe our future success depends in
substantial part on our ability to recruit, hire, motivate, develop, and retain talented personnel for all areas of our organization,
including our CEO and the other members of our senior leadership team. Doing so may be difficult due to many factors,
including fluctuations in economic and industry conditions, changes to U.S. immigration policy, competitors’ hiring and remote
working policies and practices, employee intolerance for the significant changes within, and demands on, our Company and our
industry, and the effectiveness of our compensation programs. If key employees depart or we are unable to recruit successfully,
our business could be negatively impacted. Further, inflationary cost pressures may increase our costs, including employee
compensation, and lead to increased employee attrition to the extent our compensation does not keep up with inflation,
particularly if our competitors’ compensation does.

In addition, certain members of our senior leadership team, including our CEO have term employment agreements with us. Our
inability to extend the terms of these employment agreements or to replace these members of our senior leadership team at the
end of their terms with qualified and capable successors could hinder our strategic planning and execution.

In addition, the new hybrid work model introduced during the global COVID-19 pandemic (the “Pandemic”) required T-Mobile
to change and evolve our company culture. As our culture continues to evolve, we may experience adverse impacts on our
ability to attract, retain and motivate key personnel, as existing and prospective employees may experience uncertainty about
their future roles with us. If key employees depart, our business could be negatively impacted. We may incur significant costs
in identifying, hiring and replacing employees, and we may lose significant expertise and talent. As a result, we may not be able
to meet our business plan, and our business, financial condition and operating results may be materially adversely affected.

System failures and business disruptions may prevent us from providing reliable service, which could materially
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 and
support our service offerings. System, network, or infrastructure failures resulting from a number of causes may prevent us
from providing reliable service. 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 and 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;

chronic changes in physical conditions, 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;

human error, such as responding to deceptive communications or unintentionally executing malicious code;

unauthorized access to our IT and business systems or to our network and critical infrastructure and those of our
suppliers and other providers;

supplier failures or delays; and

system failures or outages of our business systems or communications network.

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 deploy spectrum to expand and deepen our 5G coverage, maintain our quality of service, meet increasing
customer demands, and deploy new technologies. In order to expand and differentiate from our competitors, we will continue to
actively seek to make additional investment in spectrum, which could be significant.

14

The continued interest in, and acquisition of, spectrum by existing carriers and others, including speculators, may reduce our
ability to acquire and/or increase the cost of acquiring spectrum in the secondary market, including leasing, or purchasing
additional spectrum in the 2.5 GHz band, or negatively impact our ability to gain access to spectrum through other means,
including government auctions. Additionally, increased interest from third parties in acquiring spectrum may make it difficult to
renew leases of some of our existing 2.5 GHz spectrum holdings in the future. Additionally, the FCC may not be able to
provide sufficient additional spectrum to auction or we may be unable to secure the spectrum necessary to maintain or enhance
our competitive position in any auction we may elect to participate in or in the secondary market, on favorable terms or at all.
Any return on our investment in spectrum depends on our ability to attract additional customers and to provide additional
services and usage to existing customers.

The FCC, or other government entities, may impose conditions on the acquisition and use of new wireless broadband mobile
spectrum that may negatively impact our ability to obtain spectrum economically or in appropriate configurations or coverage
areas.

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 adversely affected.

We are modernizing our billing system architecture for our customers. As part of this strategy, we are converting
Sprint’s legacy customers onto T-Mobile’s billing platforms. As a result, we will operate and maintain multiple billing
systems until such conversion is completed. Any unanticipated difficulties, disruption, or significant delays in either of
these efforts could have adverse operational, financial, and reputational effects on our business.

We are currently operating and maintaining multiple billing systems and supporting platforms. We expect to continue to do so
until successful conversion of Sprint’s legacy customers to T-Mobile’s existing billing platforms. We may encounter
unanticipated difficulties or experience delays in the ongoing integration efforts with respect to billing, causing major system or
business disruptions. In addition, we or our supporting vendors may experience errors, cyber-attacks or other operational
disruptions that could negatively impact us and over which we may have limited control. Interruptions and/or failure of these
billing systems could disrupt our operations and impact our ability to provide or bill for our services, retain customers, attract
new customers, or negatively impact overall customer experience. Any occurrence of the foregoing could cause material
adverse effects on our operations and financial condition, and/or material weaknesses in our internal control over financial
reporting and reputational damage.

The challenges in satisfying the large number of Government Commitments in the required time frames and the
significant cumulative cost incurred in tracking, monitoring, and complying with them over multiple years could
continue to adversely impact our business, financial condition, and operating results.

In connection with the regulatory proceedings and approvals required to close the Transactions, we agreed to fulfill various
Government Commitments. These Government Commitments include, among other things, extensive 5G network build-out
commitments, obligations to deliver 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. Other Government Commitments relate to national
security, pricing and availability of rate plans, employment, substantial monetary contributions to support several different
organizations, and implementation of diversity, equity and inclusion initiatives. Most Government Commitments have specified
time frames for compliance and reporting, and we continue to focus on taking the actions required to fulfill them. Any failure to
fulfill our obligations under these Government Commitments in a timely manner could result in substantial fines, penalties, or
other legal and administrative actions and/or reputational harm.

We expect to continue incurring significant costs, expenses, and fees to track, monitor, comply with and fulfill our obligations
under these Government Commitments over a number of years. In addition, abiding by the Government Commitments may
divert our management’s time and energy away from other business operations and could force us to make business decisions
we would not otherwise make and forego taking actions that might be beneficial to the Company. The challenges in continuing
to satisfy the large number of Government Commitments in the required time frames and the cost incurred in tracking,
monitoring, and complying with them could also adversely impact our business, financial condition and operating results and
hinder our ability to effectively compete.

15

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 instability
caused by the war in Ukraine, and other macro-economic 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, and wholesale partners or MVNOs,
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.

Our business may be adversely impacted if we are not able to successfully manage the ongoing commercial and
transition services arrangements entered into in connection with the Prepaid Transaction and known or unknown
liabilities arising in connection therewith.

In connection with the closing of the Prepaid Transaction, we and DISH entered into certain commercial and transition services
arrangements, including a Master Network Services Agreement (the “MNSA”) and a license purchase agreement (the “DISH
License Purchase Agreement”). Pursuant to the MNSA, DISH will receive network services from the Company for a period of
seven years. As set forth in the MNSA, the Company will provide DISH, among other things, (a) legacy network services for
certain Boost Mobile prepaid end users on the Sprint network, (b) T-Mobile network services for certain end users that have
been migrated to the T-Mobile network or provisioned on the T-Mobile network by or on behalf of DISH and (c) infrastructure
mobile network operator services to assist in the access and integration of the DISH network. Pursuant to the DISH License
Purchase Agreement, DISH has agreed to purchase all of Sprint’s 800 MHz spectrum (approximately 13.5 MHz of nationwide
spectrum) for a total of approximately $3.6 billion in a transaction to be completed, subject to certain additional closing
conditions, following an application for FCC approval to be filed three years following the closing of the Merger; provided,
however, that if DISH breaches the DISH License Purchase agreement prior to the closing or fails to deliver the purchase price
following the satisfaction or waiver of all closing conditions, DISH’s sole liability will be to pay us a fee of approximately $72
million. In such instance, T-Mobile is required, unless otherwise approved under the Consent Decree, to conduct an auction of
all of Sprint’s 800 MHz spectrum under the terms set forth in the Consent Decree, but would not be required to divest such
spectrum for an amount less than $3.6 billion. The parties are required to file an application for the transfer by April 1, 2023.
The covered spectrum sale must occur within the later of three years after the closing of the Prepaid Transaction and five days
after receipt of the approval from the FCC of the application.

Failure to successfully manage these ongoing commercial and transition services arrangements entered into in connection with
the Prepaid Transaction and liabilities arising in connection therewith may result in material unanticipated problems, including
diversion of management time and energy, significant expenses and liabilities. There may also be other potential adverse
consequences and unforeseen increased expenses, or liabilities associated with the Prepaid Transaction, the occurrence of which
could materially impact our business, financial condition, liquidity, and operating results. In addition, there may be an increase
in competition from DISH and other third parties that DISH may enter into commercial agreements with, who are significantly
larger and with greater resources and scale advantages as compared to us. Such increased competition may result in our loss of
customers and other business relationships.

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

We may pursue acquisitions of, investments in 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

16

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 and business practices of the
company involved in any such transaction with our business;

difficulties in effectively integrating the financial and operational systems of the business involved in any such
transaction into (or supplanting such systems with) our financial and operational reporting infrastructure and internal
control framework in an effective and timely manner;

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.

For any or all of these reasons, as well as unknown risks, acquisitions, divestitures, investments, or mergers may have a
material adverse effect on our business, financial condition and operating results.

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, 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, and public health crises such as the 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.

We may not fully realize the synergy benefits from the Transactions in the expected time frame.

Our ability to realize the expected benefits from the Merger will depend on our ability to integrate the two businesses in a
manner that facilitates growth opportunities and achieves the projected cost savings. Although we have completed a number of
integration activities, we continue the process and may incur additional expenses as a result of challenges in combining
operations such as:

17

•

•

•

•

•

difficulties in integrating operations and systems, including intellectual property and communications systems,
administrative and information technology infrastructure, and supplier and vendor arrangements;

difficulties in operating and maintaining multiple billing and related support systems until conversion is completed;

difficulties in managing the expanded operations of a significantly larger and more complex company;

compliance with Government Commitments relating to national security; and

other potential adverse consequences and unforeseen increased expenses or liabilities associated with the Transactions.

Risks Related to Our Indebtedness

Our substantial level of indebtedness could adversely affect our business flexibility, 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
also reduce funds available for capital expenditures, any board-approved share repurchases and other activities. Those impacts
may put us at a competitive disadvantage relative to other companies with lower debt levels. Further, we may need to 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, including our ability to achieve the expected benefits of the
Transactions. 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 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.

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.

The agreements governing our indebtedness and other financings include restrictive covenants that limit our operating
flexibility.

The agreements governing our indebtedness and other financings impose operating and financial restrictions. These restrictions,
subject in certain cases to customary baskets, exceptions and maintenance and incurrence-based financial tests, together with
our debt service obligations, may limit our ability to engage in transactions and pursue strategic business opportunities. These
restrictions could limit our ability to obtain debt financing, refinance or pay principal on our outstanding indebtedness,
complete acquisitions for cash or indebtedness or react to business, economic, market and industry conditions and other
changes in our operating environment or the economy. Any future indebtedness that we incur may contain similar or more
restrictive covenants. Any failure to comply with the restrictions of our debt agreements may result in an event of default under
these agreements, which in turn may result in defaults or acceleration of obligations under these and other agreements, giving
our lenders the right to terminate the commitments they had made or the right to require us to repay all amounts then

18

outstanding plus any interest, fees, penalties, or premiums. An event of default may also compel us to sell certain assets
securing indebtedness under certain of these agreements.

Credit rating downgrades and/or inability to access debt markets could adversely affect our business, cash flows,
financial condition, and operating results.

Credit ratings impact the cost and availability of future borrowings and, as a result, cost of capital. Our current ratings reflect
each rating agency’s opinion of our financial strength, operating performance, and ability to meet our debt obligations. Our
capital structure and business model are reliant on continued access to debt markets. Each rating agency reviews our ratings
periodically, and there can be no assurance that such ratings will be maintained in the future. A downgrade in our corporate
rating and/or our issued debt ratings could impact our ability to access debt markets and adversely affect our business, cash
flows, financial condition, and operating results.

Risks Related to Legal and Regulatory Matters

Failure to maintain effective internal controls in accordance with Section 404 of the Sarbanes-Oxley Act could result in
a loss of investor confidence regarding our financial statements and reputational damage.

Under Section 404 of the Sarbanes-Oxley Act, we, along with our independent registered public accounting firm, are required
to report on the effectiveness of our internal control over financial reporting. There can be no assurance that remediation of any
material weaknesses that may be identified would be completed in a timely manner or that the remedial measures will prevent
other control deficiencies or material weaknesses. 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 may experience negative
impacts to our business financial condition or operating results, which would restrict our ability to access the capital markets,
require the expenditure of significant resources to correct the weaknesses or deficiencies, subject us to fines, penalties,
investigations, or judgments, harm our reputation, or otherwise cause a decline in trading price of our stock and investor
confidence.

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, 911 services, 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, 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. As an example, we recently won spectrum licenses in the so-called “C band” to
support our continued rollout of 5G technology and services. There have been concerns raised that use of this spectrum by
wireless carriers for 5G deployment could interfere with the altimeters in certain aircraft, and there is an ongoing discussion
between the industry, the FCC, and the FAA as to whether and how 5G operations should be limited around airports.
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 regulations, 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. For example, in response to the
Pandemic, the California Public Utilities Commission adopted a resolution providing a moratorium on customer disconnects
and late fees for certain California customers facing financial hardship. Additionally, in 2015 and 2016, the FCC established net
neutrality and privacy regimes that applied to our operations. Both sets of rules potentially subjected some of our initiatives and
practices to more burdensome requirements and heightened scrutiny by federal and state regulators, the public, edge providers,

19

and private litigants regarding whether such initiatives or practices are compliant. While the FCC rules were largely rolled back
in December 2017, the current FCC updated transparency obligations to require nutrition-style broadband label disclosures
effective potentially in 2023 that could prompt regulatory inquiries, and the FCC could decide to establish new net neutrality
requirements. In addition, some states and other jurisdictions have enacted laws in these areas (including, for example,
California and other states’ net neutrality laws, the CCPA and CPRA as discussed below) and others are considering enacting
similar laws. It also is uncertain what rules may be promulgated under the current administration (e.g., the FTC has discussed
promulgating privacy rules), perpetuating the risk and uncertainty regarding the regulatory environment and compliance around
these issues.

In addition, states are increasingly focused on the quality of service and support that wireless communications service providers
provide to their customers and several states have proposed or enacted new and potentially burdensome regulations in this area.
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.

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 and data protection may result in increased costs, legal claims,
fines against us, or reputational damage.

In January 2020, the California Consumer Privacy Act (the “CCPA”) became effective, creating new data privacy rights for
California residents and new compliance obligations for us and industry in general, in addition to private rights of action for
certain types of data breaches. Moreover, new privacy laws are being developed and/or enacted in many jurisdictions, for
example, in Colorado, Utah, Connecticut, Virginia, and in California, where the California Privacy Rights Act (“CPRA”)
(which modifies the CCPA) recently became effective. 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.

We have incurred and will continue to incur significant implementation costs to ensure compliance with the CCPA, the CPRA,
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, CPRA, 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.

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. 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.

In connection with the Transactions, we became subject to a number of legal proceedings, including a putative shareholder class
action and derivative lawsuit and a putative antitrust class action. For more information, see “– Contingencies and Litigation –
Litigation and Regulatory Matters” in Note 19 – Commitments and Contingencies of the Notes to the Consolidated Financial
Statements. It is possible that stockholders of T-Mobile and/or Sprint may file additional putative class action lawsuits or
shareholder derivative actions against the Company and the legacy T-Mobile board of directors and/or the legacy Sprint board
of directors. Among other remedies, these stockholders could seek damages. The outcome of any litigation is uncertain and any
such potential lawsuits could result in substantial costs and may be costly and distracting to management.

Additionally, on April 1, 2020, in connection with the closing of the Merger, we assumed the contingencies and litigation
matters of Sprint. Those matters include a wide variety of disputes, claims, government agency investigations and enforcement

20

actions and other proceedings. Unfavorable resolution of these matters could require making additional reimbursements and
paying additional fines and penalties.

On February 28, 2020, we received a Notice of Apparent Liability for Forfeiture and Admonishment from the FCC, which
proposed a penalty against us for allegedly violating Section 222 of the Communications Act and the FCC’s regulations
governing the privacy of customer information. We recorded an accrual for an estimated payment amount as of March 31,
2020, which is included in Accounts payable and accrued liabilities on our Consolidated Balance Sheets.

As a result of the August 2021 cyberattack, we are subject to numerous lawsuits, including consolidated class action lawsuits
seeking unspecified monetary damages, mass consumer arbitrations, a shareholder derivative lawsuit and inquiries by various
government agencies, law enforcement and other governmental authorities, and we may be subject to further regulatory
inquiries and private litigation. We are cooperating fully with regulators and vigorously defending against the class actions and
other lawsuits. On July 22, 2022, we entered into an agreement to settle the consolidated class action lawsuit. On July 26, 2022,
we received preliminary approval of the proposed settlement, which remains subject to final court approval. The court
conducted a final approval hearing on January 20, 2023, and we await a ruling from the court. If approved by the court, under
the terms of the proposed settlement, we would pay an aggregate of $350 million to fund claims submitted by class members,
the legal fees of plaintiffs’ counsel and the costs of administering the settlement. We would also commit to an aggregate
incremental spend of $150 million for data security and related technology in 2022 and 2023. In connection with the proposed
class action settlement and other settlements of separate consumer claims that have been previously completed or are currently
pending, we recorded a total pre-tax charge of approximately $400 million during the three months ended June 30, 2022. In
light of the inherent uncertainties involved in such matters and based on the information currently available to us, 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. In addition, in connection with the
January 2023 cyberattack, we have received notices of consumer class actions and regulatory inquires, to which we will
respond to in due course. Ongoing legal and other costs related to these proceedings and inquiries, as well as any potential
future proceedings and inquiries related to the August 2021 cyberattack and the January 2023 cyberattack, may be substantial,
and losses associated with any adverse judgments, settlements, penalties or other resolutions of such proceedings and inquiries
could be significant and have a material adverse impact on our business, reputation, financial condition, cash flows and
operating results.

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.

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.

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, JUMP! On Demand or other leasing programs, such as those acquired in the
Merger, has expanded 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.

21

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.

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 and in the context of our merger with Sprint. 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 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.

22

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 is a party to the SoftBank Proxy Agreement (as defined in Note 14 – SoftBank Equity Transaction to the Consolidated
Financial Statements). In addition, on June 22, 2020, DT, Claure Mobile LLC (“CM LLC”), and Marcelo Claure entered into a
Proxy, Lock-up and ROFR Agreement (the “Claure Proxy Agreement” and together with the SoftBank Proxy Agreement, the
“Proxy Agreements”). Pursuant to the Proxy Agreements, at any meeting of our stockholders, the shares of our common stock
beneficially owned by SoftBank or CM LLC will be voted in the manner as directed by DT. In addition, DT holds direct and
indirect call options that give DT the right to acquire up to approximately 35 million shares of our common stock held by
SoftBank.

Accordingly, 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 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 27, 2022 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.

23

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, DT and SoftBank 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 or SoftBank. 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.

We cannot guarantee that our 2022 Stock Repurchase Program will be fully consummated or that our 2022 Stock
Repurchase Program will enhance long-term stockholder value.

Our Board of Directors has authorized our 2022 Stock Repurchase Program for up to $14.0 billion of the Company’s common
stock through September 30, 2023, with $3.0 billion spent by the Company on share repurchases as of December 31, 2022, and
an additional $2.1 billion spent by the Company from January 1, 2023 through February 10, 2023. Any additional share
repurchases will depend upon, among other factors, our cash balances and potential future capital requirements, our results of
operations and financial condition, our ability to access capital markets, our priorities for the use of cash for other purposes, the
price of our common stock, and other factors that we may deem relevant.

The existence of the 2022 Stock Repurchase Program could cause our stock price, in certain cases, to be higher or lower than it
otherwise would be and could potentially reduce the market liquidity or have other unintended consequences for our stock. We
can provide no assurance that we will repurchase shares of our common stock at favorable prices, if at all. Although the
program is intended to enhance long-term stockholder value, there is no assurance it will do so.

In addition, the 2022 Stock Repurchase Program does not obligate the Company to acquire any particular amount of common
stock. The 2022 Stock Repurchase Program may be suspended or discontinued, or the amount to be spent by the Company to
repurchase shares could be reduced, at any time at the Company’s discretion. Any decision to reduce or discontinue
repurchasing shares of our common stock pursuant to our 2022 Stock Repurchase Program could cause the market price for our
common stock to decline and may negatively impact our reputation and investor confidence in us.

Item 5. Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity
Securities

Market Information

Our common stock is traded on the NASDAQ Global Select Market under the symbol “TMUS.” We are included within the
S&P 500 in the Wireless Telecommunication Services GICS (Global Industry Classification Standard) Sub-Industry index. As
of January 31, 2023, there were 15,719 registered stockholders of record of our common stock, but we estimate the total
number of stockholders to be much higher as a number of our shares are held by brokers or dealers for their customers in street
name.

We have never paid or declared any cash dividends on our common stock, and we do not intend to declare or pay any cash
dividends on our common stock in the foreseeable future. We currently intend to use future earnings, if any, to invest in our
business and for general corporate purposes, including the continued build-out of our 5G network, expansion of our business,
the integration of T-Mobile’s and Sprint’s businesses, and share repurchases as appropriate. Therefore, we do not anticipate
paying any cash dividends on our common stock in the foreseeable future; capital appreciation, if any, of our common stock
will be the sole source of potential gain.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Overview

The objectives of our Management’s Discussion and Analysis of Financial Condition and Results of Operations (“MD&A”) are
to provide users of our consolidated financial statements with the following:

•

•

•

A narrative explanation from the perspective of management of our financial condition, results of operations, cash
flows, liquidity and certain other factors that may affect future results;

Context to the consolidated financial statements; and

Information that allows assessment of the likelihood that past performance is indicative of future performance.

Our MD&A is provided as a supplement to, and should be read together with, our audited consolidated financial statements as
of December 31, 2022 and 2021, and for each of the three years in the period ended December 31, 2022, included in Part II,
Item 8 of this Form 10-K. Except as expressly stated, the financial condition and results of operations discussed throughout our
MD&A are those of T-Mobile US, Inc. and its consolidated subsidiaries.

Sprint Merger, Network Integration and Decommissioning Activities

Transaction Overview

On April 1, 2020, we completed the Merger with Sprint, a communications company offering a comprehensive range of
wireless and wireline communications products and services. As a result, Sprint and its subsidiaries became wholly owned
consolidated subsidiaries of T-Mobile.

The Merger has altered the size and scope of our operations, impacting our assets, liabilities, obligations, capital requirements
and performance measures. As a combined company, we have been able to enhance the breadth and depth of our nationwide 5G
network, accelerate innovation, increase competition in the U.S. wireless and broadband industries and achieve significant
synergies and cost reductions by eliminating redundancies within the combined network as well as other business processes and
operations.

For more information regarding our Business Combination Agreement, see Note 2 – Business Combinations of the Notes to the
Consolidated Financial Statements.

Merger-Related Costs

Merger-related costs associated with the Merger and acquisitions of affiliates generally include:

•

•

•

Integration costs to achieve efficiencies in network, retail, information technology and back office operations, migrate
customers to the T-Mobile network and billing systems and the impact of legal matters assumed as part of the Merger;

Restructuring costs, including severance, store rationalization and network decommissioning; and

Transaction costs, including legal and professional services related to the completion of the transactions.

Restructuring costs are disclosed in Note 20 – Restructuring Costs of the Notes to the Consolidated Financial Statements.
Merger-related costs have been excluded from our calculations of Adjusted EBITDA and Core Adjusted EBITDA, which are
non-GAAP financial measures, as we do not consider these costs to be reflective of our ongoing operating performance. See
“Adjusted EBITDA and Core Adjusted EBITDA” in the “Performance Measures” section of this MD&A. Net cash payments
for Merger-related costs, including payments related to our restructuring plan, are included in Net cash provided by operating
activities on our Consolidated Statements of Cash Flows.

We expect to incur substantially all of the remaining projected Merger-related costs of approximately $1.0 billion, excluding
capital expenditures, by the end of 2023, with the cash expenditure for the Merger-related costs extending beyond 2023.

We are evaluating additional restructuring initiatives which are dependent on consultations and negotiation with certain
counterparties and the expected impact on our business operations, which could affect the amount or timing of the restructuring
costs and related payments. We expect our principal sources of funding to be sufficient to meet our liquidity requirements and
anticipated payments associated with the restructuring initiatives.

Network Integration

As of December 31, 2022, we have decommissioned substantially all Sprint macro sites targeted for shut down. Our integration
and decommissioning initiatives also included the acceleration or termination of certain of our operating and financing leases
for cell sites, switch sites and network equipment. To achieve Merger synergies in network costs, we continue to perform
rationalization activities to identify duplicative networks, backhaul services and other agreements, in addition to
decommissioning certain small cell sites and distributed antenna systems.

To allow for the realization of these synergies associated with network integration, we retired certain legacy networks,
including the legacy Sprint CDMA network in the second quarter and the legacy Sprint LTE network in the third quarter of
2022. Customers impacted by the decommissioning of these networks have been excluded from our customer base and postpaid
account base. See the “Performance Measures” section of this MD&A for more details.

Restructuring

Upon the close of the Merger, we began implementing restructuring initiatives to realize cost efficiencies from the Merger. The
major activities associated with the restructuring initiatives to date include:

•

•

•

Contract termination costs associated with rationalization of retail stores, distribution channels, duplicative network
and backhaul services and other agreements;

Severance costs associated with the reduction of redundant processes and functions; and

The decommissioning of certain small cell sites and distributed antenna systems to achieve Merger synergies in
network costs.

For more information regarding our restructuring activities, see Note 20 – Restructuring Costs of the Notes to the Consolidated
Financial Statements.

29

Anticipated Merger Synergies

As a result of our ongoing restructuring and integration activities, we expect to realize Merger synergies by eliminating
redundancies within our combined network (see “Network Integration” above) as well as other business processes and
operations (see “Restructuring” above). For full-year 2023, we expect Merger synergies from Selling, general and
administrative expense reductions of $2.5 billion to $2.7 billion, Cost of service expense reductions of $3.1 billion to $3.2
billion and avoided network expenses of $1.6 billion.

Wireline

Previously, the operation of the legacy Sprint CDMA and LTE wireless networks was supported by the legacy Sprint Wireline
network. During the second quarter of 2022, we retired the legacy Sprint CDMA network and began the orderly shut-down of
the LTE network, which was completed during the third quarter. As a result of these actions during the second quarter of 2022,
we determined that the retirement of the legacy Sprint CDMA and LTE wireless networks triggered the need to assess the
Wireline long-lived assets for impairment, as these assets no longer support our wireless network and the associated customers
and cash flows in a significant manner. The results of this assessment indicated that certain Wireline long-lived assets were
impaired, and as a result, we recorded non-cash impairment expense of $477 million related to Wireline Property and
equipment, Operating lease right-of-use assets and Other intangible assets for the year ended December 31, 2022, all of which
relates to the impairment recognized during the three months ended June 30, 2022. We continue to provide Wireline services to
existing Wireline customers as of December 31, 2022.

For more information regarding this non-cash impairment, see Note 16 – Wireline of the Notes to the Consolidated Financial
Statements.

On September 6, 2022, we entered into the Wireline Sale Agreement to sell the Wireline Business for a total purchase price of
$1. In addition, at the consummation of the Wireline Transaction, we will enter into an agreement for IP transit services for
$700 million. Subject to the satisfaction or waiver of certain conditions and the other terms and conditions of the Wireline Sale
Agreement, the Wireline Transaction is expected to close mid-year 2023. As a result of the Wireline Sale Agreement and
related anticipated Wireline Transaction, we concluded that the Wireline Business met the held for sale criteria upon entering
into the Wireline Sale Agreement. As such, the assets and liabilities of the Wireline Business disposal group are classified as
held for sale and presented within Other current assets and Other current liabilities on our Consolidated Balance Sheets as of
December 31, 2022. In connection with the expected sale of the Wireline Business and classification of related assets and
liabilities as held for sale, we recognized a pre-tax loss of $1.1 billion during the year ended December 31, 2022, which is
included within Loss on disposal group held for sale on our Consolidated Statements of Comprehensive Income. The fair value
of the Wireline Business disposal group, less costs to sell, will be reassessed during each subsequent reporting period it remains
classified as held for sale, and any remeasurement to the lower of carrying amount or fair value less costs to sell will be
reported as an adjustment to the Loss on disposal group held for sale.

For more information regarding the Wireline Sale Agreement, see Note 16 – Wireline of the Notes to the Consolidated
Financial Statements.

Recent Cyberattacks

In August 2021, we were subject to a criminal cyberattack involving unauthorized access to T-Mobile’s systems. As a result of
the attack, we are subject to numerous arbitration demands and lawsuits, including class action lawsuits, and regulatory
inquiries as described in Note 19 – Commitments and Contingencies of the Notes to the Consolidated Financial Statements.

In connection with the proposed class action settlement and the separate settlements reached with a number of consumers, we
recorded a total pre-tax charge of approximately $400 million during the three months ended June 30, 2022. We expect to
continue to incur additional expenses in future periods, including costs to remediate the attack, resolve inquiries by various
government authorities, provide additional customer support and enhance customer protection, only some of which may be
covered and reimbursable by insurance. In addition to the committed aggregate incremental spend of $150 million for data
security and related technology in 2022 and 2023 under the proposed settlement agreement, we intend to allocate substantial
additional resources towards cybersecurity initiatives over the next several years.

During the year ended December 31, 2022, we recognized $100 million in reimbursements from insurance carriers for costs
incurred related to the August 2021 cyberattack. We are pursuing additional reimbursements from insurance carriers for costs
incurred related to the August 2021 cyberattack.

30

In January 2023, we disclosed that a bad actor was obtaining data through a single Application Programming Interface (“API”)
without authorization. Based on our investigation to date, the impacted API is only able to provide a limited set of customer
account data, including name, billing address, email, phone number, date of birth, T-Mobile account number and information
such as the number of lines on the account and plan features. The result from our investigation to date indicates that the bad
actor(s) obtained data from this API for approximately 37 million current postpaid and prepaid customer accounts, though many
of these accounts did not include the full data set. We believe that the bad actor first retrieved data through the impacted API
starting on or around November 25, 2022. We continue to investigate the incident and have notified individuals whose
information was impacted consistent with state and federal requirements.

We will respond to litigation and regulatory inquiries in connection with this incident 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
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.

Additionally, following the August 2021 cyberattack, we commenced a substantial multi-year investment working with leading
external cybersecurity experts to enhance our cybersecurity capabilities and transform our approach to cybersecurity. While we
have made progress to date, we plan to continue to make substantial investments to strengthen our cybersecurity program in
future periods.

Revenue Trends

In 2023, we expect Service revenues to continue to grow, primarily due to continued postpaid account and customer growth as
well as Postpaid Average Revenue per Account (“postpaid ARPA”) growth driven by the execution of our strategy to
continuously deepen our account relationships, including growth in High Speed Internet. We expect the increase in postpaid
service revenues to be partially offset by a decrease in Wholesale and other service revenues, primarily driven by the sale of the
Wireline business, which is expected to close mid-2023, the migration by Verizon of legacy TracFone customers off of the T-
Mobile network and as DISH services more of its Boost customers with their standalone network. We also expect lower lease
revenues as a result of the continued strategic shift in device financing from leasing to EIP.

Operating Expense Trends

In 2023, we expect Total operating expenses to decrease, primarily due to continued synergy realization benefiting Cost of
services and Selling, general and administrative expense as well as a significant decrease in Merger-related costs from $5.0
billion in 2022 to approximately $1.0 billion expected in 2023 as the majority of our integration activities have been completed.

We further expect a decrease in operating expenses, primarily Cost of services, associated with serving Wireline customers
driven by the sale of the Wireline business which is expected to close mid-2023. The trend of decreasing depreciation on leased
devices is expected to continue as a result of the continued strategic shift in device financing from leasing to EIP.

Macroeconomic Trends

Macroeconomic trends may result in adverse impacts on our business, and we continue to monitor these potential impacts,
including potential economic recession, changes in the Federal Reserve’s monetary policy, as well as geopolitical risks,
including the war in Ukraine. Such scenarios and uncertainties may affect, among others, expected credit loss activity as well as
certain fair value estimates.

To date, price inflation has not had a significant impact on our operations as we have fixed rates established through long-term
contracts for many of our most significant costs, including tower agreements and backhaul contracts. Similarly, our exposure to
the impact of rising interest rates is limited, primarily to any new debt issuances or draws on our revolving credit facility, as
interest is paid on our Senior Notes at a fixed rate. We continue to monitor the impact of these trends on the payment
performance of our customers.

Inflation Reduction Act

On August 16, 2022, President Biden signed the Inflation Reduction Act of 2022 (“IRA”) into law. The IRA includes several
changes to existing tax law, including a minimum tax on adjusted financial statement income of applicable corporations and an
excise tax on certain corporate stock buybacks. The tax provisions included in the IRA are generally effective beginning
January 1, 2023, and had no significant impact to the 2022 consolidated financial statements. Management does not expect the
IRA to have a significant impact on our operating results or cash flows in 2023, and we continue to review the IRA tax
provisions to assess impacts to our future consolidated financial statements.

The following discussion and analysis is for the year ended December 31, 2022, compared to the same period in 2021 unless
otherwise stated. For a discussion and analysis of the year ended December 31, 2021, compared to the same period in 2020,
please refer to Management’s Discussion and Analysis of Financial Condition and Results of Operations included in Part II,
Item 7 of our Annual Report on Form 10-K for the year ended December 31, 2021, filed with the SEC on February 11, 2022.

Total revenues decreased $547 million, or 1%. The components of these changes are discussed below.

Postpaid revenues increased $3.4 billion, or 8%, primarily from:

•

•

Higher average postpaid accounts; and

Higher postpaid ARPA. See “Postpaid ARPA” in the “Performance Measures” section of this MD&A.

Prepaid revenues increased $124 million, or 1%, primarily from higher average prepaid customers.

Wholesale and other service revenues decreased $527 million, or 9%, primarily from:

•

•

Lower advertising, MVNO and Wireline revenues; partially offset by

Higher Lifeline revenues.

Equipment revenues decreased $3.6 billion, or 17%, primarily from:

•

•

A decrease of $1.9 billion in lease revenues and a decrease of $599 million in customer purchases of leased devices
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; and

A decrease of $787 million in device sales revenue, excluding purchased leased devices, primarily from:

•

•

•

A decrease in the number of devices sold primarily driven by lower prepaid sales, partially offset by higher
upgrade volume for Sprint customers to facilitate their migration to the T-Mobile network;

Slightly lower average revenue per device sold, primarily driven by higher promotions, which included
promotions for Sprint customers to facilitate their migration to the T-Mobile network; and

An increase in contra-revenue primarily driven by higher imputed interest rates on EIPs, which is recognized
in Other revenues over the device financing term.

Other revenues increased $96 million, or 9%, primarily from:

•

Higher interest income driven by higher imputed interest rates on EIPs which is recognized over the device financing
term.

Total operating expenses decreased $198 million. The components of this change are discussed below.

Cost of services, exclusive of depreciation and amortization, increased $732 million, or 5%, primarily from:

•

•

•

An increase of $1.7 billion in Merger-related costs related to network decommissioning and integration costs; and

Higher site costs related to the continued build-out of our nationwide 5G network; partially offset by

Higher realized Merger synergies.

Cost of equipment sales, exclusive of depreciation and amortization, decreased $1.1 billion, or 5%, primarily from:

•

•

A decrease of $964 million in customer purchases of leased devices, 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; and
A decrease of $503 million in device cost of equipment sales, excluding purchased leased devices, primarily from:

•

•

A decrease in the number of devices sold primarily driven by lower prepaid sales, partially offset by higher
upgrade volume for Sprint customers to facilitate their migration to the T-Mobile network; partially offset by

Slightly higher average cost per device sold due to an increase in the high-end device mix; partially offset by

•

Higher device insurance claims and warranty fulfillment expense.

33

•

Cost of equipment sales for the year ended December 31, 2022, included $1.5 billion of Merger-related costs,
primarily to facilitate the migration of Sprint customers to the T-Mobile network, compared to $1.0 billion for the year
ended December 31, 2021.

Selling, general and administrative expenses increased $1.4 billion, or 7%, primarily from:

•

•

•

•

•

•

An increase of $773 million in bad debt expense and losses from sales of receivables, driven by higher receivable
balances, as well as normalization relative to muted Pandemic levels in 2021 and estimated potential future
macroeconomic impacts;

Higher legal-related expenses, net of recoveries, including $400 million recognized in June 2022 for the settlement of
certain litigation associated with the August 2021 cyberattack, partially offset by $100 million in reimbursements from
insurance carriers received in 2022 associated with the August 2021 cyberattack; and

Higher costs related to outsourced functions; partially offset by

Higher realized Merger synergies and lower Merger-related costs; and

Gains from the sale of certain IP addresses held by the Wireline Business.

Selling, general and administrative expenses for the year ended December 31, 2022, included $775 million of Merger-
related costs, primarily related to integration, restructuring and legal-related expenses, partially offset by $333 million

related costs for the year ended December 31, 2021.

Impairment expense was $477 million for the year ended December 31, 2022, due to the non-cash impairment of certain
Wireline Property and equipment, Operating lease right-of-use assets and Other intangible assets. See Note 16 - Wireline of the
Notes to the Consolidated Financial Statements for additional information. There was no impairment expense for the year ended
December 31, 2021.

•

Lower average debt outstanding and a lower average effective interest rate due to the retirement of higher interest rate
debt and the issuance of a lower gross principal amount of lower interest rate debt; offset by

Lower capitalized interest related to the deployment of our 600 MHz spectrum.

Guarantor Financial Information

In connection with our Merger with Sprint, we assumed certain registered debt to third parties issued by Sprint, Sprint
Communications LLC, formerly known as Sprint Communications, Inc. (“Sprint Communications”) and Sprint Capital
Corporation (collectively, the “Sprint Issuers”). As of December 31, 2022, all the registered debt to third parties issued by
Sprint Communications had matured and Sprint Communications no longer has any such debt outstanding.

Pursuant to the applicable indentures and supplemental indentures, the Senior Notes to affiliates and third parties issued by T-
Mobile USA, Inc. and the Sprint Issuers (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 merge, consolidate or
sell, or otherwise dispose of, substantially all of their assets.

Performance Measures

In managing our business and assessing financial performance, we supplement the information provided by our consolidated
financial statements with other operating or statistical data and non-GAAP financial measures. These operating and financial
measures are utilized by our management to evaluate our operating performance and, in certain cases, our ability to meet

36

liquidity requirements. Although companies in the wireless industry may not define each of these measures in precisely the
same way, we believe that these measures facilitate comparisons with other companies in the wireless industry on key operating
and financial measures.

Total Postpaid Accounts

A postpaid account is generally defined as a billing account number that generates revenue. Postpaid accounts generally consist
of customers that are qualified for postpaid service utilizing phones, High Speed Internet, tablets, wearables, DIGITS or other
connected devices, where they generally pay after receiving service.

In connection with the closing of the Merger, we refined our definition of wholesale customers, resulting in the reclassification of certain postpaid and
prepaid reseller customers to wholesale customers. Starting with the three months ended March 31, 2020, we discontinued reporting wholesale customers
to focus on postpaid and prepaid customers and wholesale revenues, which we consider more relevant than the number of wholesale customers given the
expansion of M2M and IoT products.

(2) Prepaid customers with a device installment billing plan historically included as Sprint postpaid customers have been reclassified to prepaid customers to

align with T-Mobile policy.

(3) Customers associated with the Sprint wireless prepaid and Boost Mobile brands that were divested on July 1, 2020, have been excluded from our reported

customers.

(4) Customers who have rate plans with monthly recurring charges which are considered insignificant have been excluded from our reported customers.
(5) Customers with postpaid phone rate plans without a phone (e.g., non-phone devices) have been reclassified from postpaid phone to postpaid other

customers to align with T-Mobile policy.

(6) Certain Sprint customers subject to collection activity for an extended period of time have been excluded from our reported customers to align with T-

Mobile policy.

(7) Miscellaneous insignificant adjustments to align with T-Mobile policy.

Total net customer additions increased 920,000, or 16%, primarily from:

•

•

•

Higher postpaid other net customer additions, primarily due to an increase in postpaid High Speed Internet net
customer additions and other connected devices, partially offset by lower net additions from mobile internet devices;
and

Higher postpaid phone net customer additions, primarily due to lower churn, partially offset by lower gross additions
driven by industry switching activity normalizing closer to pre-Pandemic levels; partially offset by

Lower prepaid net customer additions associated with the continued industry shift to postpaid plans, partially offset by
the introduction of our prepaid High Speed Internet offering and lower churn.

39

•

High Speed Internet net customer additions included in postpaid other net customer additions were 1,764,000 and
546,000 for the years ended December 31, 2022 and 2021, respectively. High Speed Internet net customer additions
included in prepaid net customer additions were 236,000 for the year ended December 31, 2022. Our prepaid High
Speed Internet launch was in the first quarter of 2022. Therefore, there were no prepaid High Speed Internet net
customer additions for the year ended December 31, 2021.

Churn

Churn represents the number of customers whose service was disconnected as a percentage of the average number of customers
during the specified period further divided by the number of months in the period. The number of customers whose service was
disconnected is presented net of customers that subsequently had their service restored within a certain period of time and
excludes customers who received service for less than a certain minimum period of time. We believe that churn provides
management, investors and analysts with useful information to evaluate customer retention and loyalty.

Postpaid Average Revenue Per Account

Postpaid ARPA represents the average monthly postpaid service revenue earned per account. Postpaid ARPA is calculated as
Postpaid revenues for the specified period divided by the average number of postpaid accounts during the period, further
divided by the number of months in the period. We believe postpaid ARPA provides management, investors and analysts with
useful information to assess and evaluate our postpaid service revenue realization and assist in forecasting our future postpaid
service revenues on a per account basis. We consider postpaid ARPA to be indicative of our revenue growth potential given the
increase in the average number of postpaid phone customers per account and increases in postpaid other customers, including
High Speed Internet, tablets, wearables, DIGITS or other connected devices.

The following table sets forth our operating measure ARPA:

An increase in High Speed Internet only accounts and increased promotional activity, including growth in rate plans
for specific customer cohorts such as Business, Military, and First Responder.

Average Revenue Per User

Average Revenue per User (“ARPU”) represents the average monthly service revenue earned per customer. ARPU is calculated
as service revenues for the specified period divided by the average number of customers during the period, further divided by
the number of months in the period. We believe ARPU provides management, investors and analysts with useful information to
assess and evaluate our service revenue per customer and assist in forecasting our future service revenues generated from our
customer base. Postpaid phone ARPU excludes postpaid other customers and related revenues, which include High Speed
Internet, tablets, wearables, DIGITS and other connected devices.

Adjusted EBITDA and Core Adjusted EBITDA

Adjusted EBITDA represents earnings before Interest expense, net of Interest income, Income tax expense, Depreciation and
amortization, stock-based compensation and certain income and expenses not reflective of our ongoing operating performance.
Core Adjusted EBITDA represents Adjusted EBITDA less device lease revenues. Adjusted EBITDA margin represents
Adjusted EBITDA divided by Service revenues. Core Adjusted EBITDA margin represents Core Adjusted EBITDA divided by
Service revenues.

Adjusted EBITDA, Adjusted EBITDA margin, Core Adjusted EBITDA and Core Adjusted EBITDA margin are non-GAAP
financial measures utilized by our management to monitor the financial performance of our operations. We historically used
Adjusted EBITDA and we currently use Core Adjusted EBITDA internally as a measure to evaluate and compensate our
personnel and management for their performance. We use Adjusted EBITDA and Core Adjusted EBITDA as benchmarks to
evaluate our operating performance in comparison to our competitors. Management believes analysts and investors use
Adjusted EBITDA and Core Adjusted EBITDA as supplemental measures to evaluate overall operating performance and to
facilitate comparisons with other wireless communications services companies because they are indicative of our ongoing

41

operating performance and trends by excluding the impact of interest expense from financing, non-cash depreciation and
amortization from capital investments, stock-based compensation, Merger-related costs, including network decommissioning
costs, impairment expense, losses on disposal groups held for sale and certain legal-related recoveries and expenses, as well as
other special income and expenses which are not reflective of our core business activities. Management believes analysts and
investors use Core Adjusted EBITDA because it normalizes for the transition in the Company’s device financing strategy, by
excluding the impact of device lease revenues from Adjusted EBITDA, to align with the exclusion of the related depreciation
expense on leased devices from Adjusted EBITDA. Adjusted EBITDA, Adjusted EBITDA margin, Core Adjusted EBITDA
and Core Adjusted EBITDA margin have limitations as analytical tools and should not be considered in isolation or as
substitutes for income from operations, net income or any other measure of financial performance reported in accordance with
GAAP.

The following table illustrates the calculation of Adjusted EBITDA and Core Adjusted EBITDA and reconciles Adjusted
EBITDA and Core Adjusted EBITDA to Net income, which we consider to be the most directly comparable GAAP financial
measure:

(1) Following the Prepaid Transaction starting on July 1, 2020, we provide MVNO services to DISH. We have included the operating income from April 1,
2020 through June 30, 2020, in our determination of Adjusted EBITDA to reflect contributions of the Prepaid Business that were replaced by the MVNO
Agreement beginning on July 1, 2020 in order to enable management, analysts and investors to better assess ongoing operating performance and trends.

(2) Stock-based compensation includes payroll tax impacts and may not agree with stock-based compensation expense on the consolidated financial

statements. Additionally, certain stock-based compensation expenses associated with the Transactions have been included in Merger-related costs.

(3) Legal-related expenses, net, consists of the settlement of certain litigation associated with the August 2021 cyberattack and is presented net of insurance

recoveries.

(4) Other, net, primarily consists of certain severance, restructuring and other expenses and income, including gains from the sale of IP addresses, not directly
attributable to the Merger which are not reflective of T-Mobile’s core business activities (“special items”), and are, therefore, excluded from Adjusted
EBITDA and Core Adjusted EBITDA.

NM - Not meaningful

Core Adjusted EBITDA increased $2.8 billion, or 12%, for the year ended December 31, 2022. The components comprising
Core Adjusted EBITDA are discussed further above.

42

The increase was primarily due to:

•

•

•

•

•

Higher Total service revenues;

Lower Cost of equipment sales, excluding Merger-related costs; and

Lower Cost of services, excluding Merger-related costs; partially offset by

Lower Equipment revenues, excluding lease revenues; and

Higher Selling, general and administrative expenses, excluding Merger-related costs, certain legal-related expenses,
net of recoveries, and other special items, such as gains from the sale of IP addresses.

Adjusted EBITDA increased $897 million, or 3%, for the year ended December 31, 2022, primarily due to the fluctuations in
Core Adjusted EBITDA, discussed above, partially offset by lower lease revenues, which decreased $1.9 billion for the year
ended December 31, 2022.

Liquidity and Capital Resources

Our principal sources of liquidity are our cash and cash equivalents and cash generated from operations, proceeds from issuance
of debt, financing leases, the sale of certain receivables and the Revolving Credit Facility (as defined below). Further, the
incurrence of additional indebtedness may inhibit our ability to incur new debt in the future to finance our business strategy
under the terms governing our existing and future indebtedness.

Operating Activities

Net cash provided by operating activities increased $2.9 billion, or 21%, primarily from:

•

•

•

A $4.1 billion decrease in net cash outflows from changes in working capital, primarily due to lower use of cash from
Short- and long-term operating lease liabilities, including the impact of a $1.0 billion advance rent payment related to
the modification of one of our master lease agreements during the year ended December 31, 2021, EIP receivables,
Other current and long-term liabilities and Inventories, partially offset by higher use of cash from Accounts receivable;
partially offset by

A $1.2 billion decrease in Net income, adjusted for non-cash income and expense.

Net cash provided by operating activities includes the impact of $3.4 billion and $2.2 billion in net payments for
Merger-related costs for the years ended December 31, 2022 and 2021, respectively.

Investing Activities

Net cash used in investing activities decreased $7.0 billion or 36%. The use of cash was primarily from:

•

•

•

$14.0 billion in Purchases of property and equipment, including capitalized interest, from the accelerated build-out of
our nationwide 5G network, including from network integration related to the Merger; and

$3.3 billion in Purchases of spectrum licenses and other intangible assets, including deposits, primarily due to $2.8
billion paid for spectrum licenses won at the conclusion of Auction 110 in February 2022 and $304 million paid in
total for spectrum licenses won at the conclusion of Auction 108 in September 2022; partially offset by

$4.8 billion in Proceeds related to beneficial interests in securitization transactions.

43

Financing Activities

Net cash used in financing activities was $6.5 billion for the year ended December 31, 2022, compared to net cash provided by
financing activities of $1.7 billion for the year ended December 31, 2021. The use of cash was primarily from:

•

•

•

•

•

$5.6 billion in Repayments of long-term debt;
$3.0 billion in Repurchases of common stock;

$1.2 billion in Repayments of financing lease obligations; and

$243 million in Tax withholdings on share-based awards; partially offset by

$3.7 billion in Proceeds from issuance of long-term debt.

Cash and Cash Equivalents

As of December 31, 2022, our Cash and cash equivalents were $4.5 billion compared to $6.6 billion at December 31, 2021.

Free Cash Flow

Free Cash Flow represents Net cash provided by operating activities less cash payments for Purchases of property and
equipment, including Proceeds from sales of tower sites and Proceeds related to beneficial interests in securitization
transactions and less Cash payments for debt prepayment or debt extinguishment costs. Free Cash Flow is a non-GAAP
financial measure utilized by management, investors and analysts of our financial information to evaluate cash available to pay
debt, repurchase shares and provide further investment in the business.

In 2022 and 2021, we received proceeds from the sale of tower sites of $9 million and $40 million, respectively, which are
included in Proceeds from sales of tower sites within Net cash used in investing activities on our Consolidated Statements of
Cash Flows. As these proceeds were from the sale of fixed assets and are used by management to assess cash available for
capital expenditures during the year, we determined the proceeds are relevant for the calculation of Free Cash Flow and
included them in the table below. Other proceeds from the sale of fixed assets for the periods presented are not significant. We
have presented the impact of the sales in the table below, which reconciles Free Cash Flow and Free Cash Flow, excluding
gross payments for the settlement of interest rate swaps, to Net cash provided by operating activities, which we consider to be
the most directly comparable GAAP financial measure.

Free Cash Flow increased $2.0 billion, or 36%. The increase was primarily impacted by the following:

•

•

•

•

Higher Net cash provided by operating activities, as described above; and

Higher Proceeds related to beneficial interests in securitization transactions, which were offset in Net cash provided by
operating activities; partially offset by

Higher Cash purchases of property and equipment, including capitalized interest.

Free Cash Flow includes $3.4 billion and $2.2 billion in net payments for Merger-related costs for the years ended
December 31, 2022 and 2021, respectively.

During the years ended December 31, 2022 and 2021, there were no significant net cash proceeds from securitization.

44

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, 2022, there was no outstanding balance under the Revolving Credit Facility. See Note 8 - Debt of the
Notes to the Consolidated Financial Statements for more information regarding the Revolving Credit Facility.

Debt Financing

As of December 31, 2022, our total debt and financing lease liabilities were $74.5 billion, excluding our tower obligations, of
which $66.8 billion was classified as long-term debt and $1.4 billion was classified as long-term financing lease liabilities.

During the year ended December 31, 2022, we issued long-term debt for net proceeds of $3.7 billion and repaid short- and long-
term debt with an aggregate principal amount of $5.6 billion.

Subsequent to December 31, 2022, on February 9, 2023, we issued $1.0 billion of 4.950% Senior Notes due 2028, $1.3 billion
of 5.050% Senior Notes due 2033 and $750 million of 5.650% Senior Notes due 2053.

For more information regarding our debt financing transactions, see Note 8 – Debt of the Notes to the Consolidated Financial
Statements.

Spectrum Auctions

In March 2021, the FCC announced that we were the winning bidder of 142 licenses in Auction 107 (C-band spectrum) for an
aggregate purchase price of $9.3 billion, excluding relocation costs. We expect to incur an additional $767 million in fixed
relocation costs, which will be paid through 2024.

In January 2022, the FCC announced that we were the winning bidder of 199 licenses in Auction 110 (3.45 GHz spectrum) for
an aggregate purchase price of $2.9 billion. At the inception of Auction 110 in September 2021, we deposited $100 million. We
paid the FCC the remaining $2.8 billion for the licenses won in the auction in February 2022.

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 the 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. Our receipt of these licenses was still
awaiting FCC final approval of the auction results as of December 31, 2022.

For more information regarding our spectrum licenses, see Note 6 – 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 in exchange for total cash consideration of $3.5 billion. The closing of this purchase
was still awaiting FCC final approval as of December 31, 2022.

For more information regarding our License Purchase Agreements, see Note 6 – Goodwill, Spectrum License Transactions and
Other Intangible Assets 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, 2022, we derecognized net receivables of $2.4 billion upon
sale through these arrangements.

For more information regarding these off-balance sheet arrangements, see Note 4 – Sales of Certain Receivables of the Notes to
the Consolidated Financial Statements.

45

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, or for the refinancing of
existing long-term debt on an opportunistic basis. Excluding liquidity that could be needed for spectrum acquisitions, 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 the execution of our
integration plan.

We determine future liquidity requirements for operations, capital expenditures and share repurchases 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 are also expected to incur substantial restructuring expenses in connection
with integrating and coordinating T-Mobile’s and Sprint’s businesses, operations, policies and procedures. See “Restructuring”
in this MD&A. While we have assumed that a certain level of Merger-related expenses will be incurred, factors beyond our
control, including required consultation and negotiation with certain counterparties, could affect the total amount or the timing
of these expenses. These expenses could exceed the costs historically borne by us and adversely affect our financial condition
and results of operations. There are a number of additional risks and uncertainties, including those due to the impact of the
Pandemic, 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, 2022.

Financing Lease Facilities

We have entered into 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, 2022, we have committed to $7.5 billion of
financing leases under these financing lease facilities, of which $1.2 billion was executed during the year ended December 31,
2022. We expect to enter into up to an additional $1.2 billion in financing lease commitments during the year ending December
31, 2023.

Capital Expenditures

Our liquidity requirements have been driven primarily by capital expenditures for spectrum licenses, the construction,
expansion and upgrading of our network infrastructure and the integration of the networks, spectrum, technology, personnel and
customer base of T-Mobile and Sprint. Property and equipment capital expenditures primarily relate to the integration of our
network and spectrum licenses, including acquired Sprint PCS and 2.5 GHz spectrum licenses, as we build out our nationwide
5G network. We expect a reduction in capital expenditures related to these efforts following 2022. Future capital expenditure
requirements will include the deployment of our recently acquired C-band and 3.45 GHz spectrum licenses.

For more information regarding our spectrum licenses, see Note 6 – Goodwill, Spectrum License Transactions and Other
Intangible Assets of the Notes to the Consolidated Financial Statements.

Stockholder Returns

We have never declared or paid any cash dividends on our common stock, and we do not intend to declare or pay any cash
dividends on our common stock in the foreseeable future.

On September 8, 2022, our Board of Directors authorized our 2022 Stock Repurchase Program for up to $14.0 billion of our
common stock through September 30, 2023. During the year ended December 31, 2022, we repurchased shares of our common
stock for a total purchase price of $3.0 billion, all of which were purchased under the 2022 Stock Repurchase Program and
occurred during the period from September 8, 2022, through December 31, 2022. As of December 31, 2022, we had up to
$11.0 billion remaining under the 2022 Stock Repurchase Program.

46

Subsequent to December 31, 2022, from January 1, 2023, through February 10, 2023, we repurchased additional shares of our
common stock for a total purchase price of $2.1 billion. As of February 10, 2023, we had up to $8.9 billion remaining under the
2022 Stock Repurchase Program.

For additional information regarding the 2022 Stock Repurchase Program, see Note 15 – Repurchases of Common Stock of the
Notes to the Consolidated Financial Statements.

Contractual Obligations

In connection with the regulatory approvals of the Transactions, we made commitments to various state and federal agencies,
including the U.S. Department of Justice and FCC.

For more information regarding these commitments, see Note 19 – Commitments and Contingencies of the Notes to the
Consolidated Financial Statements.

(3) The minimum commitment for certain obligations is based on termination penalties that could be paid to exit the contracts. Termination penalties are

included in the above table as payments due as of the earliest we could exit the contract, typically in less than one year. For certain contracts that include
fixed volume purchase commitments and fixed prices for various products, the purchase obligations are calculated using fixed volumes and contractually
fixed prices for the products that are expected to be purchased. This table does not include open purchase orders as of December 31, 2022 under normal
business purposes. See Note 19 – Commitments and Contingencies of the Notes to the Consolidated Financial Statements for further information.

(4) 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 $3.5 billion. The agreements remain subject to regulatory approval and the purchase price of
$3.5 billion is excluded from our reported purchase obligations above.

(5) Spectrum lease agreements are typically for five to 10 years with automatic renewal provisions, bringing the total term of the agreements up to 30 years.

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 or its affiliates in the ordinary course of business, including
intercompany servicing and licensing.

As of February 10, 2023, DT and SoftBank held, directly or indirectly, approximately 49.6% and 3.3%, respectively, of the
outstanding T-Mobile common stock, with the remaining approximately 47.1% 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 and the Proxy, Lock-Up and ROFR Agreement, dated June 22, 2020, by and among DT, Claure Mobile LLC, and
Marcelo Claure, DT has voting control, as of February 10, 2023, over approximately 53.3% 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, 2022, 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:
Telecommunication Kish Company, Mobile Telecommunication Company of Iran, and Telecommunication Infrastructure
Company of Iran. In addition, during the year ended December 31, 2022, DT, through certain of its non-U.S. subsidiaries,
provided basic telecommunications services to four 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 and Golgohar Trade and Technology
GmbH. These services have been terminated or are in the process of being terminated. For the year ended December 31, 2022,
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, 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, 2022, 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, 2022, 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 revenue and net profit generated by such services during the year ended December 31,
2022, 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, exclusive of leased devices, would have resulted in a decrease of approximately $3.1 billion in our
2022 depreciation expense and that a one-year decrease in the useful life would have resulted in an increase of approximately
$4.0 billion in our 2022 depreciation expense.

See Note 1 – Summary of Significant Accounting Policies and Note 5 – 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

Deferred tax assets and liabilities are recognized based on temporary differences between the financial statement and tax bases
of assets and liabilities using enacted tax rates expected to be in effect when these differences are realized. A valuation
allowance is recorded when it is more likely than not that some portion or all of a deferred tax asset will not be realized. The
ultimate realization of a deferred tax asset depends on the ability to generate sufficient taxable income of the appropriate
character and in the appropriate taxing jurisdictions within the carryforward periods available.

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.

Accounting Pronouncements Not Yet Adopted

For information regarding recently issued accounting standards, see Note 1 – Summary of Significant Accounting Policies of
the Notes to the Consolidated Financial Statements.

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. 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, 2022, we did not have outstanding balances under these facilities. See
Note 8 – Debt of the Notes to the Consolidated Financial Statements for additional information.

Item 8. Financial Statements and Supplementary Data

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 sheet of T-Mobile US, Inc. and subsidiaries (the "Company") as of
December 31, 2022, the related consolidated statements of comprehensive income, stockholders' equity, and cash flows, for the
year ended December 31, 2022, 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, 2022, 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, 2022, and the results of its operations and its cash flows for the year ended
December 31, 2022, 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,
2022, 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 audit 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 audit 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.

51

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 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 10 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 wireless communications services 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 wireless 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 wireless communications services and equipment revenue transactions which are initiated,
accumulated, and recorded in multiple systems and databases, auditing 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 revenue transactions included the following, among others:

• With the assistance of our IT specialists, we:

•

•

Identified the relevant systems and databases used to process 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 wireless
communications services 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 revenue and trends in the related subscriber data.

•

For a selection of 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.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheet of T-Mobile US, Inc. and its subsidiaries (the “Company”) as of
December 31, 2021, and the related consolidated statements of comprehensive income, of stockholders’ equity and of cash
flows for each of the two years in the period ended December 31, 2021, including the related notes (collectively referred to as
the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material
respects, the financial position of the Company as of December 31, 2021, and the results of its operations and its cash flows for
each of the two years in the period ended December 31, 2021 in conformity with accounting principles generally accepted in the
United States of America.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express

T-Mobile US, Inc.
Notes to the Consolidated Financial Statements

Note 1 – Summary of Significant Accounting Policies

Description of Business

T-Mobile US, Inc. (“T-Mobile,” “we,” “our,” “us” or the “Company”), together with its consolidated subsidiaries, is a leading
provider of mobile communications services, including voice, messaging and data, under its flagship brands, T-Mobile and
Metro™ by T-Mobile ("Metro by T-Mobile"), in the United States, Puerto Rico and the U.S. Virgin Islands. Substantially all of
our revenues were earned in, and substantially all of our long-lived assets are located in, the U.S., Puerto Rico and the U.S.
Virgin Islands. We provide mobile communications services primarily using our 4G Long Term Evolution (“LTE”) network
and our 5G technology network. We also offer a wide selection of wireless devices, including handsets, tablets and other mobile
communication devices, and accessories for sale, as well as financing through equipment installment plans (“EIP”) and leasing
through JUMP! On Demand. We also provide reinsurance for device insurance policies and extended warranty contracts
offered to our mobile communications customers. In addition to our wireless communications services, we offer fast and
reliable High Speed Internet utilizing our nationwide 5G network.

Basis of Presentation

The accompanying consolidated financial statements include the balances and results of operations of T-Mobile and our
consolidated subsidiaries. We consolidate majority-owned subsidiaries over which we exercise control, as well as variable
interest entities (“VIEs”) where we are deemed to be the primary beneficiary and VIEs, which cannot be deconsolidated, such
as those related to Tower obligations. Intercompany transactions and balances have been eliminated in consolidation. We
operate as a single operating segment.

The preparation of financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires
our management to make estimates and assumptions which affect our consolidated financial statements and accompanying
notes. Estimates are based on historical experience, where applicable, and other assumptions which our management believes
are reasonable under the circumstances, including, but not limited to, the valuation of assets acquired and liabilities assumed
through our merger (the “Merger”) with Sprint Corporation (“Sprint”) and through our acquisitions of affiliates and the
potential impacts arising from macroeconomic trends. These estimates are inherently subject to judgment and actual results
could differ from those estimates.

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 the Buyer will 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.”

The assets and liabilities of the Wireline Business disposal group are classified as held for sale and presented within Other
current assets and Other current liabilities on our Consolidated Balance Sheets as of December 31, 2022. The fair value of the
Wireline Business disposal group, less costs to sell, will be reassessed during each reporting period it remains classified as held
for sale, and any remeasurement to the lower of carrying amount or fair value less costs to sell will be reported as an adjustment
included within Loss on disposal group held for sale on our Consolidated Statements of Comprehensive Income. Unless
otherwise specified, the amounts and information presented in the Notes to the Consolidated Financial Statements include assets
and liabilities that have been reclassified as held for sale as of December 31, 2022.

Business Combinations

Assets acquired and liabilities assumed as part of a business combination are generally recorded at their fair value at the date of
acquisition. The excess of purchase price over the fair value of assets acquired and liabilities assumed is recorded as goodwill.
Determining fair value of identifiable assets, particularly intangibles, and liabilities acquired requires management to make
estimates, which are based on all available information and in some cases assumptions with respect to the timing and amount of
future revenues and expenses associated with an asset or liability. See Note 2 – Business Combinations for further discussion of
the Merger between T-Mobile and Sprint and the acquisition of the wireless telecommunications assets (the “Wireless Assets”)
of Shenandoah Personal Communications Company LLC (“Shentel”) used to provide Sprint PCS’s wireless mobility

59

communications network products in certain parts of Maryland, North Carolina, Virginia, West Virginia Kentucky, Ohio and
Pennsylvania.

Cash and Cash Equivalents

Cash equivalents consist of highly liquid money market funds and U.S. Treasury securities with remaining maturities of three
months or less at the date of purchase.

Receivables and Related Allowance for Credit Losses

Accounts Receivable

Accounts receivable balances are predominantly comprised of amounts currently due from customers (e.g., for wireless
communications services and monthly device lease payments), device insurance administrators, wholesale partners, other
carriers and third-party retail channels. Accounts receivable are presented on our Consolidated Balance Sheets at their
amortized cost basis (i.e., the receivables’ unpaid principal balance (“UPB”) as adjusted for any written-off amounts relating to
impairment), net of the allowance for credit losses. We have an arrangement to sell certain of our customer service accounts
receivable on a revolving basis, which are treated as sales of financial assets.

Equipment Installment Plan Receivables

We offer certain customers the option to pay for their devices and other purchases in installments, generally over a period of 24
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 is predominately comprised of the estimated credit risk underlying the EIP receivable,
reflecting the estimated credit worthiness of the customer. The imputed discount on receivables is amortized over the financed
installment term using the effective interest method and recognized as Other revenues on our Consolidated Statements of
Comprehensive Income.

The current portion of the EIP receivables is included in Equipment installment plan receivables, net and the long-term portion
of the EIP receivables is included in Equipment installment plan receivables due after one year, net on our Consolidated
Balance Sheets. We have an arrangement to sell certain EIP receivables on a revolving basis, which are treated as sales of
financial assets. See Note 4 – Sales of Certain Receivables for further information. Additionally, certain of our EIP receivables
included on our Consolidated Balance Sheets secure our asset-backed notes (“ABS Notes”). See Note 8 – Debt for further
information.

Allowance for Credit Losses

We maintain an allowance for credit losses by applying an expected credit loss model. Each period, management assesses the
appropriateness of the level of allowance for credit losses by considering credit risk inherent within each portfolio segment as
of period end. Each portfolio segment is comprised of pools of receivables that are evaluated collectively based on similar risk
characteristics. Our allowance levels consider estimated credit risk over the contractual life of the receivables and are
influenced by receivable volumes, receivable delinquency status, historical loss experience and other conditions that affect loss
expectations, such as changes in credit and collections policies and forecasts of macroeconomic conditions. While we attribute
portions of the allowance to our respective accounts receivable and EIP portfolio segments, the entire allowance is available to
credit losses related to the total receivable portfolio.

We consider a receivable past due and delinquent when a customer has not paid us by the contractually specified payment due
date. Account balances are written off against the allowance for credit losses if collection efforts are unsuccessful and the
receivable balance is deemed uncollectible (customer default), based on factors such as customer credit ratings as well as the
length of time the amounts are past due.

If there is a deterioration of our customers’ financial condition or if future actual default rates on receivables in general
differ from those currently anticipated, we will adjust our allowance for credit losses accordingly.

60

Inventories

Inventories consist primarily of wireless devices and accessories, which are valued at the lower of cost or net realizable value.
Cost is determined using standard cost, which approximates average cost. Shipping and handling costs paid to wireless device
and accessories vendors as well as costs to refurbish used devices are included in the standard cost of inventory. Net realizable
value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of disposal and
transportation. We record inventory write-downs to net realizable value for obsolete and slow-moving items based on inventory
turnover trends and historical experience.

Deferred Purchase Price Assets

In connection with the sales of certain service and EIP accounts receivable pursuant to the sale arrangements, we have deferred
purchase price assets measured at fair value that are based on a discounted cash flow model using unobservable Level 3 inputs,
including estimated customer default rates and credit worthiness. See Note 4 – Sales of Certain Receivables for further
information.

Long-Lived Assets

Long-lived assets include assets that do not have indefinite lives, such as property and equipment and certain intangible assets.
Substantially all of our long-lived assets are located in the U.S., including Puerto Rico and the U.S. Virgin Islands. We assess
potential impairments to our long-lived assets when events or changes in circumstances indicate the carrying amount of the
asset may not be recoverable. If any indicators of impairment are present, we test recoverability. The carrying value of a long-
lived asset or asset group is not recoverable if the carrying value exceeds the sum of the estimated undiscounted future cash
flows expected to be generated from the use and eventual disposition of the asset or asset group. If the estimated undiscounted
future cash flows do not exceed the asset or asset group’s carrying amount, then an impairment loss is recorded, measured as
the amount by which the carrying amount of a long-lived asset or asset group exceeds its estimated fair value.

During the second quarter of 2022, we determined that the retirement of the legacy Sprint CDMA and LTE wireless networks
triggered the need to separately assess the Wireline long-lived asset group for impairment and the results of this assessment
indicated that certain Wireline long-lived assets were impaired. See Note 16 - Wireline for further information.

Property and Equipment

Property and equipment consists of buildings and equipment, wireless communications systems, leasehold improvements,
capitalized software, leased wireless devices and construction in progress. Buildings and equipment include certain network
server equipment. Wireless communications systems include assets to operate our wireless network and information technology
data centers, including tower assets, leasehold improvements and asset retirement costs. Leasehold improvements include asset
improvements other than those related to the wireless network.

Property and equipment are recorded at cost less accumulated depreciation and impairments, if any, in Property and equipment,
net on our Consolidated Balance Sheets. We generally depreciate property and equipment over the period the property and
equipment provide economic benefit using the straight-line method. Depreciable life studies are performed periodically to
confirm the appropriateness of depreciable lives for certain categories of property and equipment. These studies take into
account actual usage, physical wear and tear, replacement history and assumptions about technology evolution. When these
factors indicate the useful life of an asset is different from the previous assessment, the remaining book value is depreciated
prospectively over the adjusted remaining estimated useful life. Leasehold improvements are depreciated over the shorter of
their estimated useful lives or the related lease term.

Costs of major replacements and improvements are capitalized. Repair and maintenance expenditures which do not enhance or
extend the asset’s useful life are charged to operating expenses as incurred. Construction costs, labor and overhead incurred in
the expansion or enhancement of our wireless network are capitalized. Capitalization commences with pre-construction period
administrative and technical activities, which include obtaining zoning approvals and building permits, and ceases at the point
at which the asset is ready for its intended use. We capitalize interest associated with the acquisition or construction of certain
property and equipment. Capitalized interest is reported as a reduction in interest expense and depreciated over the useful life of
the related assets.

We record an asset retirement obligation for the estimated fair value of legal obligations associated with the retirement of
tangible long-lived assets and a corresponding increase in the carrying amount of the related asset in the period in which the

61

obligation is incurred. In periods subsequent to initial measurement, we recognize changes in the liability resulting from the
passage of time and revisions to either the timing or the amount of the original estimate. Over time, the liability is accreted to its
present value and the capitalized cost is depreciated over the estimated useful life of the asset. Our obligations relate primarily
to certain legal obligations to remediate leased property on which our network infrastructure and administrative assets are
located.

We capitalize certain costs incurred in connection with developing or acquiring internal use software. Capitalization of software
costs commences once the final selection of the specific software solution has been made and management authorizes and
commits to funding the software project and ceases once the project is ready for its intended use. Capitalized software costs are
included in Property and equipment, net on our Consolidated Balance Sheets and are amortized on a straight-line basis over the
estimated useful life of the asset. Costs incurred during the preliminary project stage, as well as maintenance and training costs,
are expensed as incurred.

Device Leases

Through the Merger, we acquired device lease contracts in which Sprint is the lessor (the “Sprint Flex Lease Program”),
substantially all of which are classified as operating leases, as well as the associated fixed assets (i.e., the leased devices). These
leased devices were recorded as fixed assets at their acquisition date fair value and presented within Property and equipment,
net on our Consolidated Balance Sheets. Beginning in 2021, we discontinued offering the Sprint Flex lease program and are
shifting customer device financing to EIP plans.

Our leasing programs (“Leasing Programs”), which include JUMP! On Demand and the Sprint Flex Lease Program, allow
customers to lease a device (handset or tablet) generally over an initial period of 18 months and upgrade the device with a new
device when eligibility requirements are met. We depreciate leased devices to their estimated residual value, on a group basis,
using the straight-line method over the estimated useful life of the device. The estimated useful life reflects the period for which
we estimate the group of leased devices will provide utility to us, which may be longer than the initial lease term based on
customer options in the Sprint Flex Lease program to renew the lease on a month-to-month basis after the initial lease term
concludes. In determining the estimated useful life, we consider the lease term (e.g., 18 months and month-to-month renewal
options for the Sprint Flex Lease Program), trade-in activity and write-offs for lost and stolen devices. Lost and stolen devices
are incorporated into the estimates of depreciation expense and recognized as an adjustment to accumulated depreciation when
the loss event occurs. Our policy of using the group method of depreciation has been applied to acquired leased devices as well
as leases originated subsequent to the Merger. Acquired leased devices are grouped based on the age of the device. Revenues
associated with the leased devices, net of lease incentives, are generally recognized on a straight-line basis over the lease term.

For arrangements in which we are the lessor of devices, we separate lease and non-lease components.

Upon device upgrade or at lease end, customers in the JUMP! On Demand lease program must return or purchase their device,
and customers in the Sprint Flex Lease Program have the option to return or purchase their device or to renew their lease on a
month-to-month basis. The purchase price of the device is established at lease commencement and is based on the type of
device leased and any down payment made. The Leasing Programs do not contain any residual value guarantees or variable
lease payments, and there are no restrictions or covenants imposed by these leases. Returned devices, including those received
upon device upgrade, are transferred from Property and equipment, net to Inventory on our Consolidated Balance Sheets and
are valued at the lower of cost or net realizable value, with any write-down recognized as Cost of equipment sales on our
Consolidated Statements of Comprehensive Income.

Other Intangible Assets

Intangible assets that do not have indefinite useful lives are amortized over their estimated useful lives.

Through the Merger, we acquired 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 (Educational Broadband
Services or “EBS spectrum”) in the 2.5 GHz band. In addition to the Agreements with educational institutions and private
owners who hold the licenses, we also acquired direct ownership of spectrum licenses previously acquired by Sprint through
government auctions or other acquisitions.

The Agreements with educational and certain non-profit institutions are typically for terms of five to 10 years with automatic
renewal provisions, bringing the total term of the Agreements up to 30 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.

62

Leased FCC spectrum licenses are recorded as executory contracts whereby, as a result of business combination accounting, an
intangible asset or liability is recorded reflecting the extent to which contractual terms are favorable or unfavorable to current
market rates. These intangible assets or liabilities are amortized over the estimated remaining useful life of the lease
agreements. Contractual lease payments are recognized on a straight-line basis over the remaining term of the arrangement,
including renewals, and are presented in Costs of services on our Consolidated Statements of Comprehensive Income.

Customer lists and the Sprint trade name are amortized using the sum-of-the-years digits method over the period in which the
asset is expected to contribute to future cash flows. Reacquired rights are amortized on a straight-line basis over the remaining
term of the Management Agreement (as defined in Note 2 – Business Combinations), which represents the period of expected
economic benefit. The remaining finite-lived intangible assets are amortized using the straight-line method.

Goodwill and Indefinite-Lived Intangible Assets

Goodwill

Goodwill consists of the excess of the purchase price over the fair value of identifiable net assets acquired in a business
combination and is assigned to our one reporting unit: wireless.

Spectrum Licenses

Spectrum licenses are carried at costs incurred to acquire the spectrum licenses and the costs to prepare the spectrum licenses
for their intended use, such as costs to clear acquired spectrum licenses. The FCC issues spectrum licenses which provide us
with the exclusive right to utilize designated radio frequency spectrum within specific geographic service areas to provide
wireless communications services. Spectrum licenses are issued for a fixed period of time, typically up to 15 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 the arrangement, if the transaction
has been deemed to have commercial substance, spectrum licenses are reviewed for impairment. The licenses are transferred at
their carrying value, as adjusted for any impairment recognized, to assets held for sale, which is included in Other current assets
on our Consolidated Balance Sheets until approval and completion of the exchange or sale. 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.

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, which are recorded as
indefinite-lived intangible assets.

Impairment

We assess the carrying value of our goodwill and other indefinite-lived intangible assets, such as our spectrum license portfolio,
for potential impairment annually as of December 31 or more frequently, if events or changes in circumstances indicate such
assets might be impaired.

We test goodwill on a reporting unit basis by comparing the estimated fair value of the reporting unit to its book value. If the
fair value exceeds the book value, then no impairment is measured. As of December 31, 2022, we have identified one reporting

63

unit for which discrete financial information is available and results are regularly reviewed by management: wireless. The
wireless reporting unit consists of all the assets and liabilities of T-Mobile US, Inc.

When assessing goodwill for impairment we may elect to first perform a qualitative assessment to determine if the quantitative
impairment test is necessary. If we do not perform a qualitative assessment, or if the qualitative assessment indicates it is more
likely than not that the fair value of a reporting unit is less than its carrying amount, we perform a quantitative test. We
recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however,
the loss recognized would not exceed the total amount of goodwill allocated to that reporting unit. In 2022, we employed a
qualitative approach to assess the wireless reporting unit. The fair value of the wireless reporting unit is determined using a
market approach, which is based on market capitalization. We recognize market capitalization is subject to volatility and will
monitor changes in market capitalization to determine whether declines, if any, necessitate an interim impairment review. In the
event market capitalization does decline below its book value, we will consider the length, severity and reasons for the decline
when assessing whether potential impairment exists, including considering whether a control premium should be added to the
market capitalization. We believe short-term fluctuations in share price may not necessarily reflect the underlying aggregate fair
value. No events or change in circumstances have occurred that indicate the fair value of the wireless reporting unit may be
below its carrying amount at December 31, 2022.

We test our spectrum licenses for impairment on an aggregate basis, consistent with our management of the overall business at
a national level. We may elect to first perform a qualitative assessment to determine whether it is more likely than not that the
fair value of an intangible asset is less than its carrying value. If we do not perform the qualitative assessment, or if the
qualitative assessment indicates it is more likely than not that the fair value of the intangible asset is less than its carrying
amount, we calculate the estimated fair value of the intangible asset. If the estimated fair value of the spectrum licenses is lower
than their carrying amount, an impairment loss is recognized for the difference. In 2022, we employed the qualitative method.

We estimate fair value of spectrum licenses using the Greenfield methodology. The Greenfield methodology values the
spectrum licenses by calculating the cash flow generating potential of a hypothetical start-up company that goes into business
with no assets except for the asset to be valued (in this case, spectrum licenses) and makes investments required to build an
operation comparable to current use. The value of the spectrum licenses can be considered as equal to the present value of the
cash flows of this hypothetical start-up company. We base the assumptions underlying the Greenfield methodology on a
combination of market participant data and our historical results, trends and business plans. Future cash flows in the Greenfield
methodology are based on estimates and assumptions of market participant revenues, EBITDA margin, network build-out
period and a long-term growth rate for a market participant. The cash flows are discounted using a weighted-average cost of
capital. No events or change in circumstances have occurred that indicate the fair value of the Spectrum licenses may be below
their carrying amount at December 31, 2022.

The valuation approaches utilized to estimate fair value for the purposes of the impairment tests of goodwill and spectrum
licenses require the use of assumptions and estimates, which involve a degree of uncertainty. If actual results or future
expectations are not consistent with the assumptions used in our estimate of fair value, it may result in the recording of
significant impairment charges on goodwill or spectrum licenses. The most significant assumptions within the valuation models
are the discount rate, revenues, EBITDA margins, capital expenditures and long-term growth rate.

For more information regarding our impairment assessments, see Note 1 – Summary of Significant Accounting Policies and
Note 6 – Goodwill, Spectrum License Transactions and Other Intangible Assets of the Notes to the Consolidated Financial
Statements.

Fair Value Measurements

We carry certain assets and liabilities at fair value. Fair value is defined as an exit price, representing the amount that would be
received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement
date. The three-tier hierarchy for inputs used in measuring fair value, which prioritizes the inputs based on the observability as
of the measurement date, is as follows:

Level 1
Level 2
Level 3

Quoted prices in active markets for identical assets or liabilities;
Observable inputs other than the quoted prices in active markets for identical assets and liabilities; and
Unobservable inputs for which there is little or no market data, which require us to develop assumptions of what
market participants would use in pricing the asset or liability.

64

Assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value
measurement. Our assessment of the significance of a particular input to the fair value measurement requires judgment and may
affect the placement of assets and liabilities being measured within the fair value hierarchy.

The carrying values of Cash and cash equivalents, Accounts receivable, Accounts receivable from affiliates and Accounts
payable and accrued liabilities approximate fair value due to the short-term maturities of these instruments. The carrying values
of EIP receivables approximate fair value as the receivables are recorded at their present value using an imputed interest rate.
With the exception of certain long-term fixed-rate debt, there were no financial instruments with a carrying value materially
different from their fair value. See Note 7 – Fair Value Measurements for a comparison of the carrying values and fair values of
our short-term and long-term debt.

Derivative Financial Instruments

Derivative financial instruments are recognized as either assets or liabilities and are measured at fair value. We do not use
derivatives for trading or speculative purposes.

For derivative instruments designated as cash flow hedges associated with forecasted debt issuances, changes in fair value are
reported as a component of Accumulated other comprehensive loss until reclassified into Interest expense, net in the same
period the hedged transaction affects earnings. Unrealized gains on derivatives designated in qualifying cash flow hedge
relationships are recorded at fair value as assets, and unrealized losses are recorded at fair value as liabilities.

We did not have any significant derivative instruments outstanding as of December 31, 2022 or 2021.

Revenue Recognition

We primarily generate our revenue from providing wireless communications services and selling or leasing devices and
accessories to customers. Our contracts with customers may involve more than one performance obligation, which include
wireless services, wireless devices or a combination thereof, and we allocate the transaction price between each performance
obligation based on its relative standalone selling price.

Wireless Communications Services Revenue

We generate our wireless communications services revenues from providing access to, and usage of, our wireless
communications network. Service revenues also include revenues earned for providing premium services to customers, such as
device insurance services. Service contracts are billed monthly either in advance or arrears, or are prepaid. Generally, service
revenue is recognized as we satisfy our performance obligation to transfer service to our customers. We typically satisfy our
stand-ready performance obligations, including unlimited wireless services, evenly over the contract term. For usage-based and
prepaid wireless services, we satisfy our performance obligations when services are rendered.

The enforceable duration of our contracts with customers is typically one month. 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 another party for performance obligations where we arrange for the other party to
transfer goods or services to the 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 because we are acting as an agent.

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.

Federal Universal Service Fund (“USF”) and state USF are assessed by various governmental authorities in connection with the
services we provide to our customers and are included in Cost of services. When we separately bill and collect these regulatory
fees from customers, they are recorded gross in Total service revenues on our Consolidated Statements of Comprehensive
Income. For the years ended December 31, 2022, 2021 and 2020, we recorded approximately $185 million, $216 million and
$267 million, respectively, of USF fees on a gross basis.

65

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

Wireline Revenue

Performance obligations related to our Wireline customers include the provision of domestic and international data
communications services. Wireline revenues are included in Other service revenues on our Consolidated Statements of
Comprehensive Income.

Equipment Revenues

We generate equipment revenues from the sale or lease 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 instead of assessing such activities as performance obligations. We estimate
variable consideration (e.g., device returns or certain payments to indirect dealers) primarily based on historical experience.
Equipment sales not probable of collection 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. Generally, we recognize
as a reduction of the total transaction price the effects of a financing component in contracts where customers purchase their
devices and accessories on an EIP with a term of more than one year, 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.

Our Leasing Programs allow customers to lease a device over a period of up to 18 months and upgrade the device with a new
device when eligibility requirements are met. To date, substantially all of our leased wireless devices are accounted for as
operating leases and estimated contract consideration is allocated between lease and non-lease elements (such as service and
equipment performance obligations) based on the relative standalone selling price of each performance obligation in the
contract. Lease revenues are recorded as equipment revenues and recognized as earned on a straight-line basis over the lease
term. Lease revenues on contracts not probable of collection are limited to the amount of payments received. See “Property and
Equipment” above for further information.

Imputed Interest on EIP Receivables

For EIP greater than 12 months, we record the effects of financing on all EIP receivables regardless of 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.

For transactions where we recognize a significant financing component, judgment is required to determine the discount rate.
For EIP sales, the discount rate used to adjust the transaction price primarily reflects current market interest rates and the
estimated credit risk of the customer. Customer credit behavior is inherently uncertain. See “Receivables and Allowance for
Credit Losses” above, for additional discussion on how we assess credit risk.

For receivables associated with an end service customer in which the sale of the device was not directly to the end customer
(sell-in model or devices sourced directly from OEM), the effect of imputing interest is recognized as a reduction to service
revenue over the service contract period. In these transactions, the provision of wireless communications services is the only
performance obligation as the device sale was recognized when transferred to the dealer.

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.

66

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 to a customer and is most commonly evidenced
by the price at which we sell that good or service separately in similar circumstances and to similar customers.

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.

Contract assets are included in Other current assets and Other assets and contract liabilities are included in Deferred revenue on
our Consolidated Balance Sheets. See Note 10 – Revenue from Contracts with Customers for further information.

Contract Modifications

Our service contracts allow customers to frequently modify their contracts without incurring penalties, in many cases. Each
time a contract is modified, we evaluate the change in scope or price of the contract to determine if the modification should be
treated as a separate contract, as if there is a termination of the existing contract and creation of a new contract, or if the
modification should be considered a change associated with the existing contract. We typically do not have significant impacts
from contract modifications.

Contract Costs

We incur certain incremental costs to obtain a contract that we expect to recover, such as sales commissions. We record an asset
when these incremental costs to obtain a contract are incurred and amortize them on a systematic basis that is consistent with
the transfer to the customer of the goods or services to which the asset relates.

We capitalize postpaid sales commissions for service activation as costs to acquire a contract and amortize them on a straight-
line basis over the estimated period of benefit, currently 24 months. For capitalized contract costs, determining the amortization
period over which such costs are recognized as well as assessing the indicators of impairment may require 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. Commissions paid when
the customer has a lease are treated as initial direct costs and recognized over the lease term.

Incremental costs to obtain equipment contracts (e.g., commissions paid on device and accessory sales) are recognized when the
equipment is transferred to the customer. See Note 10 – Revenue from Contracts with Customers for further information.

Leases

Cell Site, Retail Store and Office Facility Leases

We are a lessee for non-cancelable operating and financing leases for cell sites, switch sites, retail stores, network equipment,
office facilities and dark fiber. We recognize a right-of-use asset and lease liability for operating leases based on the net present
value of future minimum lease payments. The right-of-use asset for an operating lease is based on the lease liability. Lease
expense is recognized on a straight-line basis over the non-cancelable lease term and renewal periods that are considered
reasonably certain.

In addition, we have financing leases for certain network equipment. We recognize a right-of-use asset and lease liability for
financing leases based on the net present value of future minimum lease payments. The right-of-use asset for a finance lease is
based on the lease liability. Expense for our financing leases is comprised of the amortization expense associated with the right-
of-use asset and interest expense recognized based on the effective interest method.

We consider several factors in assessing whether renewal periods are reasonably certain of being exercised, including the
continued maturation of our nationwide network, technological advances within the telecommunications industry and the
availability of alternative sites. We have concluded we are not reasonably certain to exercise the options to extend or terminate
our leases. Therefore, as of the lease commencement date, our lease terms generally do not include these options. We include
options to extend or terminate a lease when we are reasonably certain that we will exercise that option.

67

In determining the discount rate used to measure the right-of-use asset and lease liability, we use rates implicit in the lease, or if
not readily available, we use our incremental borrowing rate. Our incremental borrowing rate is based on an estimated secured
rate comprised of a risk-free rate plus a credit spread as secured by our assets. Determining a credit spread as secured by our
assets may require significant judgment.

Certain of our lease agreements include rental payments based on changes in the consumer price index (“CPI”). Lease liabilities
are not remeasured as a result of changes in the CPI; instead, changes in the CPI are treated as variable lease payments and are
excluded from the measurement of the right-of-use asset and lease liability. These payments are recognized in the period in
which the related obligation is incurred. Our lease agreements do not contain any material residual value guarantees or material
restrictive covenants.

Generally, we elected the practical expedient to not separate lease and non-lease components in arrangements where we are the
lessee. For arrangements in which we are the lessor of wireless handset devices, we did not elect this practical expedient. We
did not elect the short-term lease recognition exemption; as such, leases with terms shorter than 12 months are included as a
right-of-use asset and lease liability.

Rental revenues and expenses associated with co-location tower sites are presented on a net basis under Topic 842. See Note 18
– Leases for further information.

Cell Tower Monetization Transactions

In 2012, we entered into a prepaid master lease arrangement in which we as the lessor provided the rights to utilize tower sites
and we leased back space on certain of those towers. Prior to the Merger, Sprint entered into a similar lease-out and leaseback
arrangement that we assumed in the Merger.

These arrangements are treated as failed sale leasebacks in which the proceeds received are reported as a financing obligation.
The principal payments on the tower obligations are included in Other, net within Net cash provided by (used in) financing
activities on our Consolidated Statements of Cash Flows. Our historical tower site asset costs are reported in Property and
equipment, net on our Consolidated Balance Sheets and are depreciated. See Note 9 – Tower Obligations for further
information.

Sprint Retirement Pension Plan

Through the Merger, we acquired the assets and assumed the liabilities associated with the Sprint Retirement Pension Plan (the
“Pension Plan”), which is a defined benefit pension plan providing post-retirement benefits to certain employees. As of
December 31, 2005, the Pension Plan was amended to freeze benefit plan accruals for participants.

The investments in the Pension Plan are measured at fair value on a recurring basis each quarter using quoted market prices or
the net asset value per share as a practical expedient. The projected benefit obligations associated with the Pension Plan are
determined based on actuarial models utilizing mortality tables and discount rates applied to the expected benefit term. See
Note 11 – Employee Compensation and Benefit Plans for further information on the Pension Plan.

Advertising Expense

We expense the cost of advertising and other promotional expenditures to market our services and products as incurred. For the
years ended December 31, 2022, 2021 and 2020, advertising expenses included in Selling, general and administrative expenses
on our Consolidated Statements of Comprehensive Income were $2.3 billion, $2.2 billion and $1.8 billion, respectively.

Income Taxes

Deferred tax assets and liabilities are recognized based on temporary differences between the consolidated financial statements
and tax bases of assets and liabilities using enacted tax rates expected to be in effect when these differences are realized. A
valuation allowance is recorded when it is more likely than not that some portion or all of a deferred tax asset will not be
realized. The ultimate realization of a deferred tax asset depends on the ability to generate sufficient taxable income of the
appropriate character and in the appropriate taxing jurisdictions within the carryforward periods available.

We account for uncertainty in income taxes recognized on our consolidated 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

68

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.

Other Comprehensive Income (Loss)

Other comprehensive income (loss) consists of adjustments, net of tax, related to reclassification of loss from cash flow hedges,
foreign currency translation and pension and other postretirement benefits. This is reported in Accumulated other
comprehensive loss as a separate component of stockholders’ equity until realized in earnings.

Stock-Based Compensation

Stock-based compensation expense for stock awards, which include restricted stock units (“RSUs”) and performance-based
restricted stock units (“PRSUs”), is measured at fair value on the grant date and recognized as expense, net of expected
forfeitures, over the related service period. The fair value of stock awards is based on the closing price of our common stock on
the date of grant. RSUs are recognized as expense using the straight-line method. PRSUs are recognized as expense following a
graded vesting schedule with their performance re-assessed and updated on a quarterly basis, or more frequently as changes in
facts and circumstances warrant.

Share Repurchases

On September 8, 2022, our Board of Directors authorized a stock repurchase program for up to $14.0 billion of our common
stock through September 30, 2023 (the “2022 Stock Repurchase Program”). The cost of repurchased shares, including equity
reacquisition costs, 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, are included in
Repurchases of common stock on our Consolidated Statements of Cash Flows. See Note 15 - Repurchases of Common Stock
for more information about our 2022 Stock Repurchase Program.

Earnings Per Share

Basic earnings per share is computed by dividing Net income attributable to common stockholders by the weighted-average
number of common shares outstanding for the period. Diluted earnings per share is computed by giving effect to all potentially
dilutive common shares outstanding during the period. Potentially dilutive common shares consist of outstanding stock options,
RSUs and PRSUs, calculated using the treasury stock method. See Note 17 – Earnings Per Share for further information.

Variable Interest Entities

VIEs are entities that lack sufficient equity to permit the entity to finance its activities without additional subordinated financial
support from other parties, have equity investors that do not have the ability to make significant decisions relating to the entity's
operations through voting rights, do not have the obligation to absorb the expected losses or do not have the right to receive the
residual returns of the entity. The most common type of VIE is a special purpose entity (“SPE”). SPEs are commonly used in
securitization transactions in order to isolate certain assets and distribute the cash flows from those assets to investors. SPEs are
generally structured to insulate investors from claims on the SPEs’ assets by creditors of other entities, including the creditors
of the seller of the assets, these SPEs are commonly referred to as being bankruptcy remote.

The primary beneficiary is required to consolidate the assets and liabilities of the VIE. The primary beneficiary is the party
which has both the power to direct the activities of an entity that most significantly impact the VIE's economic performance,
and through its interests in the VIE, the obligation to absorb losses or the right to receive benefits from the VIE which could
potentially be significant to the VIE. We consolidate VIEs when we are deemed to be the primary beneficiary or when the VIE
cannot be deconsolidated. See Note 4 – Sales of Certain Receivables, Note 8 – Debt and Note 9 – Tower Obligations for further
information.

In assessing which party is the primary beneficiary, all the facts and circumstances are considered, including each party’s role in
establishing the VIE and its ongoing rights and responsibilities. This assessment includes, first, identifying the activities that
most significantly impact the VIE’s economic performance; and second, identifying which party, if any, has power over those
activities. In general, the parties that make the most significant decisions affecting the VIE (such as asset managers and

69

servicers) or have the right to unilaterally remove those decision-makers are deemed to have the power to direct the activities of
a VIE.

Device Purchases Cash Flow Presentation

We classify all device purchases, whether acquired for sale or lease, as operating cash outflows as our predominant strategy is
to sell devices to customers rather than lease them. See Note 21 – Additional Financial Information for disclosures of Leased
devices transferred from inventory to property and equipment and Returned leased devices transferred from property and
equipment to inventory.

Accounting Pronouncements Adopted During the Current Year

Reference Rate Reform

In March 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2020-04,
“Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting,” and has
since modified the standard with ASU 2021-01, “Reference Rate Reform (Topic 848): Scope” and ASU 2022-06, “Reference
Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848” (together, the “reference rate reform standard”). The
reference rate reform standard provides temporary optional expedients and allows for certain exceptions to applying existing
GAAP for contract modifications and hedging relationships, subject to meeting certain criteria, that reference LIBOR or another
reference rate expected to be discontinued as a result of reference rate reform. The reference rate reform standard is available
for adoption through December 31, 2024, and the optional expedients for contract modifications must be elected for all
arrangements within a given Accounting Standards Codification (“ASC”) Topic or Industry Subtopic. As of January 1, 2022,
we have elected to apply the practical expedients provided by the reference rate reform standard for all ASC Topics and
Industry Subtopics related to eligible contract modifications as they occur. This election did not have a material impact on our
consolidated financial statements for the year ended December 31, 2022, and the impact of applying the election to future
eligible contract modifications that occur through December 31, 2024, is also not expected to be material.

Contract Assets and Contract Liabilities Acquired in a Business Combination

In October 2021, the FASB issued ASU 2021-08, “Business Combinations (Topic 805): Accounting for Contract Assets and
Contract Liabilities from Contracts with Customers.” The standard amends ASC 805 such that contract assets and contract
liabilities acquired in a business combination are added to the list of exceptions to the recognition and measurement principles
such that they are recognized and measured in accordance with ASC 606. As of January 1, 2022, we have elected to adopt this
standard, and it will be applied prospectively to all business combinations occurring after this date.

Accounting Pronouncements Not Yet Adopted

Troubled Debt Restructurings and Vintage Disclosures

In March 2022, the FASB issued ASU 2022-02, “Financial Instruments—Credit Losses (Topic 326): Troubled Debt
Restructurings and Vintage Disclosures.” The standard eliminates the accounting guidance within ASC 310-40 for troubled
debt restructurings by creditors while enhancing disclosure requirements for certain loan refinancings and restructurings by
creditors when a borrower is experiencing financial difficulty. Additionally, for public business entities, the standard requires
disclosure of current-period gross write-offs by year of origination for financing receivables and net investments in leases
within the scope of ASC 326-20. The standard will become effective for us beginning January 1, 2023, and will be applied
prospectively, with an option for modified retrospective application for provisions related to recognition and measurement of
troubled debt restructurings. Early adoption is permitted for us at any time. We plan to adopt the standard when it becomes
effective for us beginning January 1, 2023. We expect the adoption of the standard to impact our disclosure of current period
write-offs for certain receivables, but do not expect other updates in the standard to have a material impact on our consolidated
financial statements.

Note 2 – Business Combinations

Business Combination Agreement and Amendments

On April 29, 2018, we entered into a Business Combination Agreement with Sprint and the other parties named therein (as
amended, the “Business Combination Agreement”) for the Merger. The Business Combination Agreement was subsequently
amended to provide that, following the closing of the Merger and the other transactions contemplated by the Business
Combination Agreement (collectively, the “Transactions”), SoftBank would indemnify us against certain specified matters and
the loss of value arising out of, or resulting from, cessation of access to spectrum under certain circumstances and subject to
certain limitations and qualifications.

On February 20, 2020, T-Mobile, SoftBank and Deutsche Telekom AG (“DT”) entered into a letter agreement (the “Letter
Agreement”). Pursuant to the Letter Agreement, SoftBank agreed to cause its applicable affiliates to surrender to T-Mobile, for
no additional consideration, an aggregate of 48,751,557 shares of T-Mobile common stock (such number of shares, the
“SoftBank Specified Shares Amount”), effective immediately following the Effective Time (as defined in the Business
Combination Agreement), making SoftBank’s exchange ratio 11.31 shares of Sprint common stock for each share of T-Mobile
common stock. This resulted in an effective exchange ratio of approximately 11.00 shares of Sprint common stock for each
share of T-Mobile common stock immediately following the closing of the Merger, an increase from the originally agreed 9.75
shares. Sprint stockholders, other than SoftBank, received the original fixed exchange ratio of 0.10256 shares of T-Mobile
common stock for each share of Sprint common stock, or the equivalent of approximately 9.75 shares of Sprint common stock
for each share of T-Mobile common stock.

The Letter Agreement requires T-Mobile to issue to SoftBank 48,751,557 shares of T-Mobile common stock, subject to the
terms and conditions set forth in the Letter Agreement, for no additional consideration, if certain conditions are met. The
issuance of these shares is contingent on the trailing 45-day volume-weighted average price per share of T-Mobile common
stock on the NASDAQ Global Select Market being equal to or greater than $150.00, at any time during the period commencing
on April 1, 2022 and ending on December 31, 2025. If the threshold price is not met, then none of the SoftBank Specified
Shares Amount will be issued.

Closing of Sprint Merger

On April 1, 2020, we completed the Merger, and as a result, Sprint and its subsidiaries became wholly owned consolidated
subsidiaries of T-Mobile. Sprint was the fourth-largest telecommunications company in the U.S., offering a comprehensive
range of wireless and wireline communication products and services. As a combined company, we have been able to rapidly
launch a broad and deep nationwide 5G network, accelerate innovation, increase competition in the U.S. wireless and
broadband industries and achieve significant synergies and cost reductions by eliminating redundancies within the combined
network as well as other business processes and operations.

Upon completion of the Merger, each share of Sprint common stock was exchanged for 0.10256 shares of T-Mobile common
stock, or 9.75 shares of Sprint common stock for each share of T-Mobile common stock. After adjustments, including the
holdback of the SoftBank Specified Shares Amount and fractional shares, we issued 373,396,310 shares of T-Mobile common
stock to Sprint stockholders. The fair value of the T-Mobile common stock provided in exchange for Sprint common stock was
approximately $31.3 billion.

Additional components of consideration included the repayment of certain of Sprint’s debt, replacement of equity awards
attributable to pre-combination services, contingent consideration and a cash payment received from SoftBank for certain
reimbursed Merger expenses.

Immediately following the closing of the Merger and the surrender of the SoftBank Specified Shares Amount, pursuant to the
Letter Agreement described above, DT and SoftBank held, directly or indirectly, approximately 43.6% and 24.7%, respectively,
of the outstanding T-Mobile common stock, with the remaining approximately 31.7% of the outstanding T-Mobile common
stock held by other stockholders. See Note 14 – SoftBank Equity Transaction for ownership details as of December 31, 2022.

equity-based awards that relates to services performed by the employee prior to the acquisition date is included within consideration transferred, and
includes stock options, restricted stock units and performance-based restricted stock units.

(3) Represents the cash consideration paid concurrent with the close of the Merger to retire certain Sprint debt, as required by change in control provisions of

the debt, plus interest and prepayment penalties.

(4) Represents the fair value of the SoftBank Specified Shares Amount contingent consideration that may be issued as set forth in the Letter Agreement.
(5) Represents receipt of a cash payment from SoftBank for certain reimbursed Merger expenses.

The SoftBank Specified Shares Amount was determined to be contingent consideration with an acquisition-date fair value of
$1.9 billion. We estimated the fair value using the income approach, a probability-weighted discounted cash flow model,
whereby a Monte Carlo simulation method estimated the probability of different outcomes as the likelihood of achieving the
45-day volume-weighted average price threshold is not easily predicted. 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: Fair Value
Measurement. The key assumptions in applying the income approach include the estimated future share-price volatility, which
was based on historical market trends and the estimated future performance of T-Mobile.

The maximum amount of contingent consideration that could be issued to SoftBank has an estimated value of $7.3 billion,
based on SoftBank Specified Shares Amount of 48,751,557 multiplied by the defined volume-weighted average price per share
of $150.00. The contingent consideration that could be delivered to SoftBank is classified within equity and is not subject to
remeasurement.

Fair Value of Assets Acquired and Liabilities Assumed

We accounted for the Merger as a business combination. The identifiable assets acquired and liabilities assumed of Sprint were
recorded at their fair values as of the acquisition date and consolidated with those of T-Mobile. Assigning fair market values to
the assets acquired and liabilities assumed at the date of an acquisition requires the use of significant judgment regarding
estimates and assumptions. For the fair values of the assets acquired and liabilities assumed, we used the cost, income and
market approaches, including market participant assumptions.

Included in Other assets acquired is $80 million in restricted cash.

Amounts initially disclosed for the estimated values of certain acquired assets and liabilities assumed were adjusted through
March 31, 2021 (the close of the measurement period) based on information arising after the initial valuation.

Intangible Assets and Liabilities

Goodwill with an assigned value of $9.4 billion represents the excess of the consideration transferred over the fair values of
assets acquired and liabilities assumed. The goodwill recognized includes synergies expected to be achieved from the
operations of the combined company, the assembled workforce of Sprint and intangible assets that do not qualify for separate
recognition. Expected synergies from the Merger include the cost savings from the planned integration of network
infrastructure, facilities, personnel and systems. None of the goodwill resulting from the Merger is deductible for tax purposes.
All of the goodwill acquired is allocated to the wireless reporting unit.

Other intangible assets include $4.9 billion of customer relationships with a weighted-average useful life of eight years and
tradenames of $207 million with a useful life of two years. Leased spectrum arrangements that have favorable (asset) and
unfavorable (liability) terms compared to current market rates were assigned fair values of $745 million and $125 million,
respectively, with 18-year and 19-year weighted-average useful lives, respectively.

73

The fair value of Spectrum licenses of $45.4 billion was estimated using the income approach, specifically a Greenfield model.
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: Fair Value Measurement. The key assumptions in applying the income approach include
the discount rate, estimated market share, estimated capital and operating expenditures, forecasted service revenue and a long-
term growth rate for a hypothetical market participant that enters the wireless industry and builds a nationwide wireless
network.

Acquired Receivables

The fair value of the assets acquired includes Accounts receivable of $1.8 billion and EIP receivables of $1.3 billion. The UPB
under these contracts as of April 1, 2020, the date of the Merger, was $1.8 billion and $1.6 billion, respectively. The difference
between the fair value and the UPB primarily represents amounts expected to be uncollectible.

Indemnification Assets and Contingent Liabilities

Pursuant to Amendment No. 2 to the Business Combination Agreement, SoftBank agreed to indemnify us against certain
specified matters and losses. As of the acquisition date, we recorded a contingent liability and an offsetting indemnification
asset for the expected reimbursement by SoftBank for certain Lifeline matters. The liability is presented in Accounts payable
and accrued liabilities, and the indemnification asset is presented in Other current assets within our acquired assets and
liabilities at the acquisition date. In November 2020, we entered into a consent decree with the FCC to resolve certain Lifeline
matters, which resulted in a payment of $200 million by SoftBank. Final resolution of these matters could require making
additional reimbursements and paying additional fines and penalties, which we do not expect to have a significant impact on
our financial results. We expect that any additional liabilities related to these matters would be indemnified and reimbursed by
SoftBank.

Deferred Taxes

As a result of the Merger, we acquired deferred tax assets for which a valuation allowance reserve is deemed to be necessary, as
well as additional uncertain tax benefit reserves. As of the date of the Merger, the amount of the valuation allowance reserve
and uncertain tax benefit reserves was $851 million and $660 million, respectively.

Pro Forma Information

The following unaudited pro forma financial information gives effect to the Transactions as if they had been completed on
January 1, 2019. The unaudited pro forma information was prepared in accordance with the requirements of ASC 805: Business

For the periods subsequent to the Merger close date, the acquired Sprint subsidiaries contributed total revenues and operating
income of $20.5 billion and $1.3 billion, respectively, for the year ended December 31, 2020, that were included on our
Consolidated Statements of Comprehensive Income.

Regulatory Matters

The Transactions were the subject of various legal and regulatory proceedings involving a number of state and federal agencies.
In connection with those proceedings and the approval of the Transactions, we have certain commitments and other obligations
to various state and federal agencies and certain nongovernmental organizations. See Note 19 – Commitments and
Contingencies for further information.

Prepaid Transaction

On July 26, 2019, we entered into the Asset Purchase Agreement with Sprint and DISH, pursuant to which, following the
consummation of the Merger, DISH would acquire the Prepaid Business.

On June 17, 2020, T-Mobile, Sprint and DISH entered into the First Amendment to the Asset Purchase Agreement. Pursuant to
the First Amendment of the Asset Purchase Agreement, T-Mobile, Sprint and DISH agreed to proceed with the closing of the
Prepaid Transaction, in accordance with the Asset Purchase Agreement, on July 1, 2020, subject to the terms and conditions of
the Asset Purchase Agreement and the terms and conditions of the Consent Decree.

On July 1, 2020, pursuant to the Asset Purchase Agreement, we completed the Prepaid Transaction. Upon closing of the
Prepaid Transaction, we received $1.4 billion from DISH for the Prepaid Business, subject to working capital adjustments. See
Note 12 – Discontinued Operations for further information.

Shenandoah Personal Communications Company Affiliate Relationship

Sprint PCS (specifically Sprint Spectrum L.P.) was party to a variety of publicly filed agreements with Shentel, pursuant to
which Shentel was the exclusive provider of Sprint PCS’s wireless mobility communications network products in certain parts
of Maryland, North Carolina, Virginia, West Virginia, Kentucky, Ohio and Pennsylvania. Pursuant to one such agreement, the
Sprint PCS Management Agreement, dated November 5, 1999 (as amended, supplemented and modified from time to time, the
“Management Agreement”), Sprint PCS was granted an option to purchase Shentel’s Wireless Assets used to provide services
pursuant to the Management Agreement. On August 26, 2020, Sprint, now our indirect subsidiary, on behalf of and as the direct
or indirect owner of Sprint PCS, exercised its option by delivering a binding notice of exercise to Shentel.

On May 28, 2021, T-Mobile USA, Inc., a Delaware corporation and our direct wholly owned subsidiary, entered into an Asset
Purchase Agreement (the “Purchase Agreement”) with Shentel, for the acquisition of the Wireless Assets for an aggregate
purchase price of approximately $1.9 billion in cash, subject to certain adjustments prescribed by the Management Agreement
and such additional adjustments agreed by the parties.

Closing of Shentel Wireless Assets Acquisition

On July 1, 2021, upon the completion of certain customary conditions, including the receipt of certain regulatory approvals, we
closed on the acquisition of the Wireless Assets pursuant to the Purchase Agreement, and as a result, T-Mobile became the legal
owner of the Wireless Assets. Through this transaction, we reacquired the exclusive rights to deliver Sprint’s wireless network
services in Shentel’s former affiliate territory and simplified our operations. Concurrently, and as agreed to through the
Purchase Agreement, T-Mobile and Shentel entered into certain separate transactions, including the effective settlement of the
pre-existing arrangements between T-Mobile and Shentel under the Management Agreement.

75

In exchange, T-Mobile transferred cash of approximately $2.0 billion, approximately $1.9 billion of which was determined to
be consideration transferred for the Wireless Assets and the remainder of which was determined to relate to separate
transactions, primarily associated with the effective settlement of pre-existing arrangements between T-Mobile and Shentel.
Accordingly, these separate transactions are not included in the calculation of the consideration transferred in exchange for the
Wireless Assets, and the settlement of pre-existing arrangements between T-Mobile and Shentel did not result in material gains
or losses.

Prior to the acquisition of the Wireless Assets, revenues generated from our affiliate relationship with Shentel were presented as
Wholesale and other service revenues. Upon the close of the transaction, revenues generated from postpaid customers within
the reacquired territory are presented as Postpaid revenues on our Consolidated Statements of Comprehensive Income. The
financial results of the Wireless Assets since the closing through December 31, 2021, 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.

Fair Value of Assets Acquired and Liabilities Assumed

We accounted for the acquisition of the Wireless Assets as a business combination. The identifiable assets acquired and
liabilities assumed were recorded at their fair values as of the acquisition date and consolidated with those of T-Mobile.
Assigning fair market values to the assets acquired and liabilities assumed at the date of an acquisition requires the use of
significant judgment regarding estimates and assumptions. For the fair values of the assets acquired and liabilities assumed, we
used the cost, income and market approaches, including market participant assumptions.

The following table summarizes the fair values for each major class of assets acquired and liabilities assumed at the acquisition
date. We retained the services of certified valuation specialists to assist with assigning values to certain acquired assets and
assumed liabilities.

Goodwill with an assigned value of $1.0 billion, substantially all of which is deductible for tax purposes, represents the
anticipated cost savings from the operations of the combined company resulting from the planned integration of network
infrastructure and facilities, the assembled workforce hired concurrently with the acquisition of Wireless Assets, and the
intangible assets that do not qualify for separate recognition. All of the goodwill acquired is allocated to the wireless reporting
unit.

Other intangible assets include $770 million of reacquired rights to provide services in Shentel’s former affiliate territory which
is being amortized on a straight-line basis over a useful life of approximately nine years in line with the remaining term of the
Management Agreement upon the acquisition of the Wireless Assets, which represents the period of expected economic
benefits associated with the reacquisition of such rights. 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 growth rates, revenue over an estimated period of time, the
discount rate, estimated capital expenditures, estimated income taxes and the long-term growth rate, as well as forecasted
earnings before interest, taxes, depreciation and amortization (“EBITDA”) margins.

Note 3 – Receivables and Related Allowance for Credit Losses

We maintain an allowance for credit losses by applying an expected credit loss model. Each period, management assesses the
appropriateness of the level of allowance for credit losses by considering credit risk inherent within each portfolio segment as
of the end of the period.

We consider a receivable past due when a customer has not paid us by the contractually specified payment due date. Account
balances are written off against the allowance for credit losses if collection efforts are unsuccessful and the receivable balance is
deemed uncollectible (customer default), based on factors such as customer credit ratings as well as the length of time the
amounts are past due.

Our portfolio of receivables is comprised of two portfolio segments: accounts receivable and EIP receivables.

Accounts Receivable Portfolio Segment

Accounts receivable balances are predominately comprised of amounts currently due from customers (e.g., for wireless
communications services and monthly device lease payments), device insurance administrators, wholesale partners, non-
consolidated affiliates, 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 adjusted for asset-specific considerations, current
economic conditions and reasonable and supportable forecasts.

Our approach considers a number of factors, including our overall historical credit losses, net of recoveries, and payment
experience, as well as current collection trends such as write-off frequency and severity. We also consider other qualitative
factors such as current and forecasted macroeconomic conditions.

We consider the need to adjust our estimate of credit losses for reasonable and supportable forecasts of future macroeconomic
conditions. To do so, we monitor external forecasts of changes in real U.S. gross domestic product and forecasts of consumer
credit behavior for comparable credit exposures. We also periodically evaluate other macroeconomic indicators such as
unemployment rates to assess their level of correlation with our historical credit loss statistics.

EIP Receivables Portfolio Segment

Based upon customer credit profiles at the time of customer origination, we classify the EIP receivables segment into two
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.

Installment receivables acquired in the Merger are included in EIP receivables. We applied our proprietary credit scoring model
to the customers acquired in the Merger with an outstanding EIP receivable balance. Based on tenure, consumer credit risk
score and credit profile, these acquired customers were classified into our customer classes of Prime or Subprime. For EIP
receivables acquired in the Merger, the difference between the fair value and UPB of the receivable at the acquisition date is
accreted to interest income over the contractual life of the receivable using the effective interest method. EIP receivables had a
combined weighted-average effective interest rate of 8.0% and 5.6% as of December 31, 2022, and 2021, respectively.

Many of our loss estimation techniques rely on delinquency-based models; therefore, delinquency is an important indicator of
credit quality in the establishment of our allowance for credit losses for EIP receivables. We manage our EIP receivables
portfolio segment using delinquency and customer credit class as key credit quality indicators.

The following table presents the amortized cost of our EIP receivables by delinquency status, customer credit class and year of

We estimate credit losses on our EIP receivables segment by applying an expected credit loss model, which relies on historical
loss data adjusted for current conditions to calculate default probabilities or an estimate for the frequency of customer default.
Our assessment of default probabilities or frequency includes receivables delinquency status, historical loss experience, how
long the receivables have been outstanding and customer credit ratings, as well as customer tenure. We multiply these estimated
default probabilities by our estimated loss given default, which is the estimated amount or severity of the default loss after
adjusting for estimated recoveries.

As we do for our accounts receivable portfolio segment, we consider the need to adjust our estimate of credit losses on EIP
receivables for reasonable and supportable forecasts of economic conditions through monitoring external forecasts and periodic
internal statistical analyses.

Credit loss activity increased during 2022, as activity normalized relative to muted Pandemic levels in 2021 and other
macroeconomic trends contributed to adverse scenarios and presented additional uncertainty due to, for example, the potential
effects associated with higher inflation, rising interest rates and changes in the Federal Reserve’s monetary policy, as well as
geopolitical risks, including the war in Ukraine.

Off-Balance-Sheet Credit Exposures

We do not have material off-balance-sheet credit exposures as of December 31, 2022. In connection with the sales of certain
service and EIP accounts receivable pursuant to the sale arrangements, we have 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 customer default rates and credit worthiness, dilutions and recoveries. See Note 4 – Sales of Certain Receivables for
further information.

Note 4 – Sales of Certain Receivables

We regularly enter into transactions to sell certain service accounts receivable and EIP receivables. The transactions, including
our continuing involvement with the sold receivables and the respective impacts to our consolidated financial statements, are
described below.

Sales of EIP Receivables

Overview of the Transaction

In 2015, we entered into an arrangement to sell certain EIP receivables on a revolving basis (the “EIP sale arrangement”). The
maximum funding commitment of the EIP sale arrangement is $1.3 billion. On November 2, 2022, we extended the scheduled
expiration date of the EIP sale arrangement to November 18, 2023.

As of both December 31, 2022 and 2021, the EIP sale arrangement provided funding of $1.3 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

79

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 which 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 on our consolidated financial statements.

The following table summarizes the carrying amounts and classification of assets, which consist primarily of the deferred
purchase price, included on our Consolidated Balance Sheets with respect to the EIP BRE:

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 limited 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 $950 million and the
facility expires in February 2023. As of both December 31, 2022 and 2021, the service receivable sale arrangement provided
funding of $775 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 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, nor does the third party qualify as a VIE.

Variable Interest Entity

Prior to the March 2021 amendment of the service receivable sale arrangement, the Service BRE did not qualify as a VIE, but
due to the significant level of control we exercised over the entity, it was consolidated.

In March 2021, the amendment to the service receivable sale arrangement triggered a VIE reassessment, and we determined
that the Service BRE now qualifies as a VIE. 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 on our consolidated financial
statements.

purchase price, and liabilities included on our Consolidated Balance Sheets with respect to the Service BRE:

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 limited
recourse to our general credit.

Sales of Receivables

The transfers of service receivables 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 recognize the cash proceeds received upon sale in Net cash provided by operating activities on our Consolidated Statements
of Cash Flows. We recognize proceeds net of the deferred purchase price, consisting of a receivable from the purchasers that
entitles us to certain collections on the receivables. We recognize the collection of the deferred purchase price in Net cash used
in investing activities on our Consolidated Statements of Cash Flows as Proceeds related to beneficial interests in securitization
transactions.

The deferred purchase price represents a financial asset that is primarily tied to the creditworthiness of the customers and which
can be settled in such a way that we may not recover substantially all of our recorded investment, due to default by the
customers on the underlying receivables. At inception, we elected to measure the deferred purchase price at fair value with
changes in fair value included in Selling, general and administrative expense on our Consolidated Statements of Comprehensive
Income. The fair value of the deferred purchase price is determined based on a discounted cash flow model which uses
primarily Level 3 inputs, including customer default rates. As of December 31, 2022 and 2021, our deferred purchase price
related to the sales of service receivables and EIP receivables was $692 million and $779 million, respectively.

administrative expense on our Consolidated Statements of Comprehensive Income.

As of both December 31, 2022 and 2021, the total principal balance of outstanding transferred service receivables and EIP
receivables was $1.0 billion.

81

Continuing Involvement

Pursuant to the sale arrangements described above, we have continuing involvement with the service accounts receivable and
EIP receivables we sell as we service the receivables, are required to repurchase certain receivables, including ineligible
receivables, aged receivables and receivables where a write-off is imminent, and may be responsible for absorbing credit losses
through reduced collections on our deferred purchase price assets. We continue to service the customers and their related
receivables, including facilitating customer payment collection, in exchange for a monthly servicing fee. As the receivables are
sold on a revolving basis, the customer payment collections on sold receivables may be reinvested in new receivable sales. At
the direction of the purchasers of the sold receivables, we apply the same policies and procedures while servicing the sold
receivables as we apply to our owned receivables, and we continue to maintain normal relationships with our customers.

Postpaid Billing System Impairment

In connection with the continuing integration of the businesses following the Merger, we evaluated the long-term billing system
architecture strategy for our postpaid customers. In order to facilitate customer migration from the Sprint legacy billing
platform, our postpaid billing system replacement plan and associated development will no longer serve our future needs. As a
result, we recorded a non-cash impairment of $200 million related to capitalized software development costs for the year ended
December 31, 2020. The expense is included in Impairment expense on our Consolidated Statements of Comprehensive
Income.

Wireline Impairment

Previously, the operation of the legacy Sprint CDMA and LTE wireless networks was supported by the legacy Sprint Wireline
network. During the second quarter of 2022, we retired the legacy Sprint CDMA network and began the orderly shut-down of
the LTE network. We determined that the retirement of the legacy Sprint CDMA and LTE wireless networks triggered the need
to assess the Wireline long-lived assets for impairment, as these assets no longer support our wireless network and the
associated customers and cash flows in a significant manner. The results of this assessment indicated that certain Wireline long-
lived assets were impaired. See Note 16 - Wireline for further information.

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 judgement.

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, 2022.

In the year ended December 31, 2020, we recognized a goodwill impairment of $218 million for the Layer3 reporting unit. The
impairment was the result of our enhanced in-home broadband opportunity following the Merger, along with the acquisition of
certain content rights, which has created a strategic shift in our TVisionTM services offering. The expense is included in
Impairment expense on our Consolidated Statements of Comprehensive Income.

The fair value of spectrum licenses includes the value associated with aggregating a nationwide portfolio of owned and leased
spectrum.

Favorable spectrum leases represent a contract where the market rate is higher than the future contractual lease payments. We
lease this spectrum from third parties who hold the spectrum licenses. As these contracts pertain to intangible assets, they are
excluded from the lease accounting guidance (ASC 842) and are accounted for as service contracts in which the expense is
recognized on a straight-line basis over the lease term. Favorable spectrum leases of $745 million were recorded as an
intangible asset as a result of purchase accounting and are being amortized on a straight-line basis over the associated remaining
lease term. Additionally, we recognized unfavorable spectrum lease liabilities of $125 million, which are also amortized over
their respective remaining lease terms and are included in Other liabilities on our Consolidated Balance Sheets.

The customer relationship intangible assets represent the value associated with the acquired Sprint customers. The customer
relationship intangible assets are amortized using the sum-of-the-years digits method over periods of up to eight years.

Other intangible assets are amortized over the remaining period that the asset is expected to provide a benefit to us.

Identifiable Intangible Assets Acquired in the Shentel Acquisition

We reacquired certain rights under the Management Agreement in connection with the acquisition of the Wireless Assets that
provided us the ability to fully do business in Shentel’s former affiliate territories. We recognized an intangible asset for these
reacquired rights at its fair value of $770 million as of July 1, 2021. The reacquired rights intangible asset is being amortized on
a straight-line basis over a useful life of approximately nine years in line with the remaining term of the Management
Agreement upon the acquisition of the Wireless Assets.

In March 2021, the FCC announced that we were the winning bidder of 142 licenses in Auction 107 (C-band spectrum) for an
aggregate purchase price of $9.3 billion, excluding relocation costs. We expect to incur an additional $767 million in fixed
relocation costs, which will be paid through 2024.

84

In January 2022, the FCC announced that we were the winning bidder of 199 licenses in Auction 110 (mid-band spectrum) for
an aggregate purchase price of $2.9 billion. At inception of Auction 110 in September 2021, we deposited $100 million. We
paid the FCC the remaining $2.8 billion for the licenses won in the auction in February 2022. On May 4, 2022, the FCC issued
to us the licenses won in Auction 110. The licenses are included in Spectrum licenses on our Consolidated Balance Sheets as of
December 31, 2022.

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. The aggregate cash payments made to the
FCC are included in Other assets on our Consolidated Balance Sheets as of December 31, 2022, and will remain there until the
corresponding licenses are received. The timing of when the licenses will be issued will be determined by the FCC after all
post-auction procedures have been completed.

Cash payments to acquire spectrum licenses and payments for costs to clear spectrum are included in Purchases of spectrum
licenses and other intangible assets, including deposits, on our Consolidated Statements of Cash Flows for the year ended
December 31, 2022.

As of December 31, 2022, the activities that are necessary to get the C-band, mid-band and 2.5 GHz spectrum ready for its
intended use have not begun; as such, capitalization of the interest associated with the costs of acquiring these spectrum licenses
has not begun.

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 has the option to purchase certain 800 MHz spectrum licenses for a total of
approximately $3.6 billion in a transaction to be completed, subject to an application for FCC approval, by July 1, 2023, or
within five days of FCC approval, whichever date is later.

In the event DISH breaches the DISH License Purchase Agreement or fails to deliver the purchase price following the
satisfaction or waiver of all closing conditions, DISH is liable to pay us a fee of $72 million. Additionally, if DISH does not
exercise the option to purchase the 800 MHz spectrum licenses, we are required, unless otherwise approved under the Consent
Decree, to offer the licenses for sale through an auction. If the specified minimum price of $3.6 billion is not met in the auction,
we would be relieved of the obligation to sell the licenses.

Channel 51 License Co LLC and LB License Co, LLC

On August 8, 2022, we, Channel 51 License Co LLC and LB License Co, LLC (together with Channel 51 License Co LLC, the
“Sellers”) entered into License Purchase Agreements pursuant to which we will acquire spectrum in the 600 MHz band from
the Sellers in exchange for total cash consideration of $3.5 billion. The licenses will be acquired without any associated
networks, but are currently being utilized through exclusive leasing arrangements with the Sellers.

The parties have agreed that closing will occur within 180 days after the receipt of required regulatory approvals, and payment
of the $3.5 billion purchase price will occur no later than 40 days after the date of such closing. We anticipate the transactions
will close in mid- to late-2023.

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, 2022.

Note 7 – Fair Value Measurements

The carrying values of Cash and cash equivalents, Accounts receivable and Accounts payable and accrued liabilities
approximate fair value due to the short-term maturities of these instruments. The carrying values of EIP receivables
approximate fair value as the receivables are recorded at their present value using an imputed interest rate.

Derivative Financial Instruments

Periodically, we use derivatives to manage exposure to market risk, such as interest rate risk. We designate certain derivatives
as hedging instruments in a qualifying hedge accounting relationship to help minimize significant, unplanned fluctuations in
cash flows or fair values caused by designated market risks, such as interest rate volatility. We do not use derivatives for trading
or speculative purposes.

Cash flows associated with qualifying hedge derivative instruments are presented in the same category on our Consolidated
Statements of Cash Flows as the item being hedged. For fair value hedges, the change in the fair value of the derivative
instruments is recognized in earnings through the same income statement line item as the change in the fair value of the hedged
item. For cash flow hedges, the change in the fair value of the derivative instruments is reported in Other comprehensive
income (loss) and recognized in earnings when the hedged item is recognized in earnings, again, through the same income
statement line item.

We did not have any significant derivative instruments outstanding as of December 31, 2022 or 2021.

86

Interest Rate Lock Derivatives

During the three months ended March 31, 2020, we made net collateral transfers to certain of our derivative counterparties
totaling $580 million, which are included in Net cash related to derivative contracts under collateral exchange arrangements
within Net cash used in investing activities on our Consolidated Statements of Cash Flows.

Between April 2 and April 6, 2020, in connection with the issuance of an aggregate of $19.0 billion of Senior Secured Notes,
we terminated our interest rate lock derivatives.

At the time of termination, the interest rate lock derivatives were a liability of $2.3 billion, of which $1.2 billion was cash-
collateralized. The cash flows associated with the settlement of interest rate lock derivatives are presented on a gross basis on
our Consolidated Statements of Cash Flows, with the total cash payments to settle the swaps of $2.3 billion presented in
changes in Other current and long-term liabilities within Net cash provided by operating activities and the return of cash
collateral of $1.2 billion presented as an inflow in Net cash related to derivative contracts under collateral exchange
arrangements within Net cash used in investing activities for the year ended December 31, 2020.

Aggregate changes in the fair value of the interest rate lock derivatives, net of tax and amortization, of $1.3 billion and
$1.5 billion are presented in Accumulated other comprehensive loss on our Consolidated Balance Sheets as of December 31,
2022 and 2021, respectively.

For the years ended December 31, 2022, 2021 and 2020, $203 million, $189 million and $128 million, respectively, were
amortized from Accumulated other comprehensive loss into Interest expense, net, on our Consolidated Statements of
Comprehensive Income. We expect to amortize $219 million of the Accumulated other comprehensive loss associated with the
derivatives into Interest expense, net, over the 12 months ending December 31, 2023.

Deferred Purchase Price Assets

In connection with the sales of certain service and EIP accounts receivable pursuant to the sale arrangements, we have deferred
purchase price assets measured at fair value that are based on a discounted cash flow model using unobservable Level 3 inputs,
including customer default rates. See Note 4 – Sales of Certain Receivables for further information.

The carrying amounts of our deferred purchase price assets, which are measured at fair value on a recurring basis and are
included on our Consolidated Balance Sheets, were $692 million and $779 million as of December 31, 2022 and 2021,
respectively. Fair value was equal to the carrying amount at December 31, 2022 and 2021.

Debt

The fair value of our Senior Notes to third parties was determined based on quoted market prices in active markets, and
therefore were classified as Level 1 within the fair value hierarchy. The fair value of our Senior Notes to affiliates was
determined based on a discounted cash flow approach using market interest rates of instruments with similar terms and
maturities and an estimate for our standalone credit risk. Accordingly, our Senior Notes to affiliates were classified as Level 2
within the fair value hierarchy. The fair value of our ABS Notes was determined based on quoted prices in inactive markets for
identical instruments and observable changes in market interest rates, both of which are Level 2 inputs, as well as projected
changes in cash collections on the underlying pool of receivables securing the ABS Notes, which is a Level 3 input. Due to the
overcollateralization of the ABS Notes, projected changes in cash collections, such as changes resulting from customer default
rates, on the pool of receivables securing such notes do not significantly affect the fair value estimate of the ABS Notes and
therefore such 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, considerable judgment was required in interpreting market data to develop fair value estimates for the Senior
Notes to affiliates. The fair value estimates were based on information available as of December 31, 2022 and 2021. 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 3.9% and 4.1% for
the years ended December 31, 2022 and 2021, respectively, on weighted-average debt outstanding of $72.5 billion and
$74.0 billion for the years ended December 31, 2022 and 2021, respectively. The weighted-average debt outstanding was

89

calculated by applying an average of the monthly ending balances of total short-term and long-term debt and short-term and
long-term debt to affiliates, net of unamortized premiums, discounts, debt issuance costs and consent fees.

Senior Secured Notes

Following the achievement of an investment grade issuer rating from each of the three main credit rating agencies, on August
22, 2022, we entered into an amendment (“Credit Agreement Amendment”) to our Credit Agreement, dated April 1, 2020 to
release the liens securing the obligations under the Credit Agreement. Upon effectiveness of the Credit Agreement Amendment,
the liens securing the Senior Secured Notes were also automatically released, and our obligations under the Senior Secured
Notes (thereafter, together with our other senior unsecured notes, “Senior Notes”), which for the avoidance of doubt exclude the
Spectrum-Backed Notes, are no longer secured.

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 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 one to three years.

On September 15, 2022, T-Mobile USA and certain of its affiliates, as guarantors, issued an aggregate of $3.0 billion of Senior
Notes bearing interest from 5.200% to 5.800% and maturing in 2033 to 2062, and used the net proceeds of $3.0 billion for
general corporate purposes, including among other things, share repurchases and refinancing of existing indebtedness on an
ongoing basis.

Subsequent to December 31, 2022, on February 9, 2023, we issued $1.0 billion of 4.950% Senior Notes due 2028, $1.3 billion
of 5.050% Senior Notes due 2033 and $750 million of 5.650% Senior Notes due 2053. We intend to use the net proceeds of
$3.0 billion for general corporate purposes, which may include among other things, share repurchases and refinancing of
existing indebtedness on an ongoing basis.

Credit Facilities

On October 17, 2022, we entered into an Amended and Restated Credit Agreement (the “October 2022 Credit Agreement”)
with certain financial institutions named therein. The October 2022 Credit Agreement amends and restates in its entirety the
Credit Agreement originally dated April 1, 2020, and provides for a $7.5 billion revolving credit facility, including a letter of
credit sub-facility of up to $1.5 billion, and a swingline loan sub-facility of up to $500 million. Commitments under the October
2022 Credit Agreement will mature on October 17, 2027, except as otherwise extended or replaced. Borrowings under the
October 2022 Credit Agreement will bear interest based upon the applicable benchmark rate, depending on the type of loan and,
in some cases, at our election, plus a margin that is determined by reference to the credit rating of T-Mobile USA’s senior
unsecured long-term debt. The October 2022 Credit Agreement contains customary representations, warranties and covenants,
including a financial maintenance covenant of 4.5x with respect to T-Mobile USA, Inc.’s Leverage Ratio (as defined therein)
commencing with the period ended December 31, 2022. As of December 31, 2022, we did not have an outstanding balance
under this facility.

loss on extinguishment of debt for the year ended December 31, 2022.

Asset-backed Notes

On October 12, 2022, we issued $750 million of 4.910% Class A Senior ABS Notes to third-party investors in a private
placement transaction. Our ABS Notes are secured by $1.0 billion of gross EIP receivables and future collections on such
receivables.

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 2.5 years. Under the terms of the transaction, there is a two-year 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.

The ABS Notes are redeemable, in whole but not in part, on or after the payment date in November 2023. If redeemed on or
after the payment date in November 2024, or if the aggregate principal balance of the transferred EIP receivables is equal to or
less than 10% of the aggregate principal balance of the EIP receivables transferred upon issuance of the ABS Notes, we can
redeem the ABS Notes without incurring a Make-Whole Payment; otherwise, a Make-Whole Payment applies.

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.

91

Net proceeds of $746 million from our ABS Notes are reflected in Proceeds from issuance of long-term debt on our
Consolidated Statements of Cash Flows in the year ended December 31, 2022. The ABS Notes issued and the assets securing
this debt are included on our Consolidated Balance Sheets.

The ABS Entities meet the definition of a VIE for which we have determined that we are the primary beneficiary as we have the
power to direct the activities of the ABS Entities that most significantly impact their performance. Those activities include
selecting which receivables are transferred into the ABS Entities, servicing such receivables, and funding of the ABS Entities.
Additionally, our equity interest and residual interest in the ABS BRE and the ABS Trust, respectively, obligate us to absorb
losses and gives us the right to receive benefits from the ABS Entities that could potentially be significant to the ABS Entities.
Accordingly, we include the balances and results of operations of the ABS Entities in our consolidated financial statements.

Balance Sheets with respect to the ABS Entities:

Spectrum Financing

On April 1, 2020, in connection with the closing of the Merger, we assumed Sprint’s spectrum-backed notes, which are
collateralized by the acquired, directly held and third-party leased Spectrum licenses (collectively, the “Spectrum Portfolio”)
transferred to wholly owned bankruptcy-remote special purpose entities (collectively, the “Spectrum Financing SPEs”). As of
December 31, 2022 and 2021, the total outstanding obligations under these Notes was $3.0 billion and $3.5 billion,
respectively.

In October 2016, certain subsidiaries of Sprint Communications, Inc. transferred the Spectrum Portfolio to the Spectrum
Financing SPEs, which was used as collateral to raise an initial $3.5 billion in senior secured notes (the “2016 Spectrum-
Backed Notes”) bearing interest at 3.360% per annum under a $7.0 billion securitization program. The 2016 Spectrum-Backed
Notes were repayable over a five-year term, with interest-only payments over the first four quarters and amortizing quarterly
principal payments thereafter commencing December 2017 through September 2021. We fully repaid the 2016 Spectrum-
Backed Notes in 2021.

In March 2018, Sprint issued approximately $3.9 billion in aggregate principal amount of senior secured notes (the “2018
Spectrum-Backed Notes” and together with the 2016 Spectrum-Backed Notes, the “Spectrum-Backed Notes”) under the
existing $7.0 billion securitization program, consisting of two series of senior secured notes. The first series of notes totaled
$2.1 billion in aggregate principal amount, bears interest at 4.738% per annum, and has quarterly interest-only payments until
June 2021, with additional quarterly principal payments commencing in June 2021 through March 2025. As of December 31,
2022, $525 million of the aggregate principal amount was classified as Short-term debt on our Consolidated Balance Sheets.
The second series of notes totaled approximately $1.8 billion in aggregate principal amount, bears interest at 5.152% per
annum, and has quarterly interest-only payments until June 2023, with additional quarterly principal payments commencing in
June 2023 through March 2028. As of December 31, 2022, $276 million of the aggregate principal amount was classified as

92

Short-term debt on our Consolidated Balance Sheets. The Spectrum Portfolio, which also serves as collateral for the Spectrum-
Backed Notes, remains substantially identical to the original portfolio from October 2016.

Simultaneously with the October 2016 offering, Sprint Communications, Inc. entered into a long-term lease with the Spectrum
Financing SPEs for the ongoing use of the Spectrum Portfolio. Sprint Communications, Inc. is required to make monthly lease
payments to the Spectrum Financing SPEs in an aggregate amount that is market-based relative to the spectrum usage rights as
of the closing date and equal to $165 million per month. The lease payments, which are guaranteed by T-Mobile subsidiaries
subsequent to the Merger, are sufficient to service all outstanding series of the 2016 Spectrum-Backed Notes and the lease also
constitutes collateral for the senior secured notes. Because the Spectrum Financing SPEs are wholly owned T-Mobile
subsidiaries subsequent to the Merger, these entities are consolidated and all intercompany activity has been eliminated.

Each Spectrum Financing SPE is a separate legal entity with its own separate creditors who will be entitled, prior to and upon
the liquidation of the respective Spectrum Financing SPE, to be satisfied out of the Spectrum Financing SPE’s assets prior to
any assets of such Spectrum Financing SPE becoming available to T-Mobile. Accordingly, the assets of each Spectrum
Financing SPE are not available to satisfy the debts and other obligations owed to other creditors of T-Mobile until the
obligations of such Spectrum Financing SPE under the Spectrum-Backed Notes are paid in full. Certain provisions of the
Spectrum Financing facility require us to maintain specified cash collateral balances. Amounts associated with these balances
are considered to be restricted cash.

Restricted Cash

Certain provisions of our debt agreements require us to maintain specified cash collateral balances. Amounts associated with
these balances are considered to be restricted cash.

Standby Letters of Credit

For the purposes of securing our obligations to provide device insurance services and for the purposes of securing our general
purpose obligations, we maintain an agreement for standby letters of credit with certain financial institutions. We assumed
certain of Sprint’s standby letters of credit in the Merger. Our outstanding standby letters of credit were $352 million and $441
million as of December 31, 2022 and 2021, respectively.

Note 9 – Tower Obligations

Existing CCI Tower Lease Arrangements

In 2012, we conveyed to Crown Castle International Corp. (“CCI”) the exclusive right to manage and operate approximately
6,200 tower sites (“CCI Lease Sites”) via a master prepaid lease with site lease terms ranging from 23 to 37 years. CCI has
fixed-price purchase options for the CCI Lease Sites totaling approximately $2.0 billion, exercisable annually on a per-tranche
basis at the end of the lease term during the period from December 31, 2035, through December 31, 2049. If CCI exercises its
purchase option for any tranche, it must purchase all the towers in the tranche. We lease back a portion of the space at certain
tower sites.

Assets and liabilities associated with the operation of the tower sites were transferred to special purpose entities (“SPEs”).
Assets included ground lease agreements or deeds for the land on which the towers are situated, the towers themselves and
existing subleasing agreements with other mobile network operator tenants that lease space at the tower sites. Liabilities
included the obligation to pay ground lease rentals, property taxes and other executory costs.

We determined the SPEs containing the CCI Lease Sites (“Lease Site SPEs”) are VIEs as they lack sufficient equity to finance
their activities. We have a variable interest in the Lease Site SPEs but are not the primary beneficiary as we lack the power to
direct the activities that most significantly impact the Lease Site SPEs’ economic performance. These activities include
managing tenants and underlying ground leases, performing repair and maintenance on the towers, the obligation to absorb
expected losses and the right to receive the expected future residual returns from the purchase option to acquire the CCI Lease
Sites. As we determined that we are not the primary beneficiary and do not have a controlling financial interest in the Lease Site
SPEs, the Lease Site SPEs are not included on our consolidated financial statements.

However, we also considered if this arrangement resulted in the sale of the CCI Lease Sites for which we would derecognize
the tower assets. By assessing whether control had transferred, we concluded that transfer of control criteria, as discussed in the
revenue standard, were not met. Accordingly, we recorded this arrangement as a financing whereby we recorded debt, a
financial obligation, and the CCI Lease Sites tower assets remained on our Consolidated Balance Sheets. We recorded long-

93

term financial obligations in the amount of the net proceeds received and recognize interest on the tower obligations. The tower
obligations are increased by interest expense and amortized through contractual leaseback payments made by us to CCI and
through net cash flows generated and retained by CCI from the operation of the tower sites.

Acquired CCI Tower Lease Arrangements

Prior to the Merger, Sprint entered into a lease-out and leaseback arrangement with Global Signal Inc., a third party that was
subsequently acquired by CCI, that conveyed to CCI the exclusive right to manage and operate approximately 6,400 tower sites
(“Master Lease Sites”) via a master prepaid lease. These agreements were assumed upon the close of the Merger, at which point
the remaining term of the lease-out was approximately 17 years with no renewal options. CCI has a fixed price purchase option
for all (but not less than all) of the leased or subleased sites for approximately $2.3 billion, exercisable one year prior to the
expiration of the agreement and ending 120 days prior to the expiration of the agreement. We lease back a portion of the space
at certain tower sites.

We considered if this arrangement resulted in the sale of the Master Lease Sites for which we would derecognize the tower
assets. By assessing whether control had transferred, we concluded that transfer of control criteria, as discussed in the revenue
standard, were not met. Accordingly, we recorded this arrangement as a financing whereby we recorded debt, a financial
obligation, and the Master Lease Sites tower assets remained on our Consolidated Balance Sheets.

As of the closing date of the Merger, we recognized Property and equipment with a fair value of $2.8 billion and tower
obligations related to amounts owed to CCI under the leaseback of $1.1 billion. Additionally, we recognized $1.7 billion in
Other long-term liabilities associated with contract terms that are unfavorable to current market rates, which include
unfavorable terms associated with the fixed-price purchase option in 2037.

We recognize interest expense on the tower obligations. The tower obligations are increased by the interest expense and
amortized through contractual leaseback payments made by us to CCI. The tower assets are reported in Property and
equipment, net on our Consolidated Balance Sheets and are depreciated to their estimated residual values over the expected
useful life of the towers, which is 20 years.

Leaseback Arrangement

On January 3, 2022, we entered into an agreement (the “Crown Agreement”) with CCI. The Crown Agreement extends the
current term of the leasebacks by up to 12 years and modifies the leaseback payments for both the Existing CCI Tower Lease
Arrangement and the Acquired CCI Tower Lease Arrangement. As a result of the Crown Agreement, there was an increase in
our financing obligation as of the effective date of the Crown Agreement of approximately $1.2 billion, with a corresponding
decrease to Other long-term liabilities associated with unfavorable contract terms. The modification resulted in a revised
interest rate under the effective interest method for the tower obligations: 11.6% for the Existing CCI Tower Lease
Arrangement and 5.3% for the Acquired CCI Tower Lease Arrangement. There were no changes made to either of our master
prepaid leases with CCI.

The following table summarizes the balances associated with both of the tower arrangements on our Consolidated Balance
Sheets:

Future minimum payments related to the tower obligations are approximately $424 million for the 12-month period ending
December 31, 2023, $816 million in total for both of the 12-month periods ending December 31, 2024 and 2025, $788 million
in total for both of the 12-month periods ending December 31, 2026 and 2027, and $4.5 billion in total thereafter.

We are contingently liable for future ground lease payments through the remaining term of the CCI Lease Sites and the Master
Lease Sites. These contingent obligations are not included in Operating lease liabilities as any amount due is contractually owed
by CCI based on the subleasing arrangement. Under the arrangement, we remain primarily liable for ground lease payments on
approximately 900 sites and have included lease liabilities of $246 million in our Operating lease liabilities as of December 31,
2022.

Note 10 – Revenue from Contracts with Customers

Disaggregation of Revenue

We provide wireless communications services to three primary categories of customers:

• Postpaid customers generally include customers who are qualified to pay after receiving wireless communications

services utilizing phones, High Speed Internet, tablets, wearables, DIGITS or other connected devices;

• Prepaid customers generally include customers who pay for wireless communications services in advance; and

• Wholesale customers include Machine-to-Machine and Mobile Virtual Network Operator customers that operate on

our network but are managed by wholesale partners.

Postpaid service revenues, including postpaid phone revenues and postpaid other revenues, were as follows:

Contract assets primarily represent revenue recognized for equipment sales with promotional bill credits offered to customers
that are paid over time and are contingent on the customer maintaining a service contract.

Contract asset balances increased primarily due to an increase in promotions with an extended service contract, partially offset
by billings on existing contracts and impairment, which is recognized as bad debt expense. The current portion of our contract
assets of approximately $356 million and $219 million as of December 31, 2022, and 2021, respectively, was included in Other
current assets on our Consolidated Balance Sheets.

Contract liabilities are recorded when fees are collected, or we have an unconditional right to consideration (a receivable) in
advance of delivery of goods or services. Changes in contract liabilities are primarily related to the activity of prepaid
customers. Contract liabilities are primarily included in Deferred revenue on our Consolidated Balance Sheets.

Remaining Performance Obligations

As of December 31, 2022, the aggregate amount of transaction price allocated to remaining service performance obligations for
postpaid contracts with subsidized devices and promotional bill credits that result in an extended service contract is $1.4 billion.
We expect to recognize revenue as the service is provided on these postpaid contracts over an extended contract term of 24
months from the time of origination.

Information about remaining performance obligations that are part of a contract that has an original expected duration of one
year or less has been excluded from the above, which primarily consists of monthly service contracts.

Certain of our wholesale, roaming and service contracts include variable consideration based on usage and performance. This
variable consideration has been excluded from the disclosure of remaining performance obligations. As of December 31, 2022,
the aggregate amount of the contractual minimum consideration for wholesale, roaming and service contracts is $2.3 billion,
$1.9 billion and $3.4 billion for 2023, 2024, and 2025 and beyond, respectively. These contracts have a remaining duration
ranging from less than one year to seven years.

Contract Costs

The balance of deferred incremental costs to obtain contracts with customers was $1.9 billion and $1.5 billion as of
December 31, 2022, and December 31, 2021, respectively, and is included in Other assets on our Consolidated Balance Sheets.
Deferred contract costs incurred to obtain postpaid service contracts are amortized over a period of 24 months. The amortization
period is monitored to reflect any significant change in assumptions. Amortization of deferred contract costs included in
Selling, general and administrative expenses on our Consolidated Statements of Comprehensive Income were $1.5 billion,
$1.1 billion and $865 million for the years ended December 31, 2022, 2021 and 2020, respectively.

The deferred contract cost asset is assessed for impairment on a periodic basis. There were no impairment losses recognized on
deferred contract cost assets for the years ended December 31, 2022, 2021 and 2020.

Note 11 – Employee Compensation and Benefit Plans

Under our 2013 Omnibus Incentive Plan and the Sprint Corporation Amended and Restated 2015 Omnibus Incentive Plan that
T-Mobile assumed in connection with the closing of the Merger (the “Incentive Plans”), we are authorized to issue up to 101
million shares of our common stock. Under our Incentive Plans, we can grant stock options, stock appreciation rights, restricted
stock, restricted stock units (“RSUs”), and performance awards to eligible employees, consultants, advisors and non-employee
directors. As of December 31, 2022, there were approximately 15 million shares of common stock available for future grants
under our Incentive Plans.

We grant RSUs to eligible employees, key executives and certain non-employee directors and PRSUs to eligible key
executives. RSUs entitle the grantee to receive shares of our common stock upon vesting (with vesting generally occurring
annually over a three-year service period), subject to continued service through the applicable vesting date. PRSUs entitle the
holder to receive shares of our common stock at the end of a performance period of generally up to three years if the applicable
performance goals are achieved and generally subject to continued service through the applicable performance period. The
number of shares ultimately received by the holder of PRSUs is dependent on our business performance against the specified
performance goal(s) over a pre-established performance period. We also maintain an employee stock purchase plan (“ESPP”),
under which eligible employees can purchase our common stock at a discounted price.

Upon the completion of our Merger with Sprint, T-Mobile assumed Sprint’s stock compensation plans. In addition, pursuant to
the Business Combination Agreement, at the Effective Time, each outstanding option to purchase Sprint common stock (other
than under Sprint’s Employee Stock Purchase Plan), each award of time-based RSUs in respect of shares of Sprint common
stock and each award of performance-based RSUs in respect of shares of Sprint common stock, in each case, that was
outstanding immediately prior to the Effective Time was automatically adjusted by the Exchange Ratio (as defined in the
Business Combination Agreement) and converted into an equity award of the same type covering shares of T-Mobile common
stock, on the same terms and conditions (including, if applicable, any continuing vesting requirements (but excluding any
performance-based vesting conditions)) under the applicable Sprint plan and award agreement in effect immediately prior to the
Effective Time (the “Assumed Awards”). The applicable amount of performance-based RSUs eligible for conversion was based
on formulas and approximated 100% of target. Any accrued but unpaid dividend equivalents with respect to any such award of
time-based RSUs or performance-based RSUs were assumed by T-Mobile at the Effective Time and became an obligation with
respect to the applicable award of RSUs in respect of shares of T-Mobile common stock.

On April 22, 2020, we filed a Registration Statement on Form S-8 to register a total of 25,304,224 shares of common stock,
representing those covered by the Sprint Corporation 1997 Long-Term Stock Incentive Program, the Sprint Corporation 2007
Omnibus Incentive Plan (the “Sprint 2007 Plan”) and the Sprint Corporation Amended and Restated 2015 Omnibus Incentive
Plan (the “2015 Plan”) that T-Mobile assumed in connection with the closing of the Merger. This included 7,043,843 shares of
T-Mobile common stock issuable upon exercise or settlement of the Assumed Awards held by current directors, officers,
employees and consultants of T-Mobile or its subsidiaries who were directors, officers, employees and consultants of Sprint or
its subsidiaries immediately prior to the Effective Time, as well as (i) 12,420,945 shares of T-Mobile common stock that remain
available for issuance under the 2015 Plan and (ii) 5,839,436 additional shares of T-Mobile common stock subject to awards
granted under the 2015 Plan that may become available for issuance under the 2015 Plan if any awards under the 2015 Plan are
forfeited, lapse unexercised or are settled in cash.

(1) Represents PRSUs granted prior to 2022 for which the performance achievement period was completed in 2022, resulting in incremental unit awards.

These PRSU awards are also included in the amount vested in 2022.

PRSUs included in the table above are shown at target. Share payout can range from 0% to 200% based on different
performance outcomes. Weighted-average grant date fair value of RSU and PRSU awards assumed through acquisition is based
on the fair value on the date assumed.

Payment of the underlying shares in connection with the vesting of RSU and PRSU awards generally triggers a tax obligation
for the employee, which is required to be remitted to the relevant tax authorities. With respect to RSUs and PRSUs settled in
shares, we have agreed to withhold shares of common stock otherwise issuable under the RSU and PRSU awards to cover
certain of these tax obligations, with the net shares issued to the employee accounted for as outstanding common stock. We
withheld 1,900,710, 2,511,512 and 4,441,107 shares of common stock to cover tax obligations associated with the payment of
shares upon vesting of stock awards and remitted cash of $243 million, $316 million and $439 million to the appropriate tax
authorities for the years ended December 31, 2022, 2021 and 2020, respectively.

Employee Stock Purchase Plan

Our ESPP allows eligible employees to contribute up to 15% of their eligible earnings toward the semi-annual purchase of our
shares of common stock at a discounted price, subject to an annual maximum dollar amount. Employees can purchase stock at a
15% discount applied to the closing stock price on the first or last day of the six-month offering period, whichever price is
lower. The number of shares issued under our ESPP was 2,079,086, 2,189,542 and 2,144,036 for the years ended December 31,
2022, 2021 and 2020, respectively. As of December 31, 2022, the number of securities remaining available for future sale and
issuance under the ESPP was 4,985,230. Sprint’s ESPP was terminated prior to the Merger close and legacy Sprint employees
were eligible to enroll in our ESPP on August 15, 2020.

Our ESPP provides for an annual increase in the aggregate number of shares of our common stock reserved for sale and
authorized for issuance thereunder as of the first day of each fiscal year (beginning with fiscal year 2016) equal to the lesser of
(i) 5,000,000 shares of our common stock, and (ii) the number of shares of T-Mobile common stock determined by the
Compensation Committee of the Board of Directors of the Company (the “Compensation Committee”). For fiscal years 2016
through 2019, the Compensation Committee determined that no such increase in shares of our common stock was necessary.
However, an additional 5,000,000 shares of our common stock were automatically added to the ESPP share reserve as of each
of January 1, 2020 and January 1, 2021. No additional shares of our common stock were automatically added as of January 1,
2022 and 2023.

Stock Options

Stock options outstanding relate to the Metro Communications, Inc. 2010 Equity Incentive Compensation Plan, the Amended
and Restated Metro Communications, Inc. 2004 Equity Incentive Compensation Plan, the Layer3 TV, Inc. 2013 Stock Plan, the
Sprint 2007 Plan and the Sprint 2015 Plan (collectively, the “Stock Option Plans”). No stock option awards were granted during

Weighted-average grant date fair value of stock options assumed through acquisition is based on the fair value on the date assumed.

Stock options exercised under the Stock Option Plans generated proceeds of approximately $7 million, $10 million and $48
million for the years ended December 31, 2022, 2021 and 2020, respectively.

The grant-date fair value of share-based incentive compensation awards attributable to post-combination services including
restricted stock units and stock options, from the Merger was approximately $163 million.

Pension and Other Postretirement Benefits Plans

Upon the completion of our Merger with Sprint, we acquired the assets and assumed the liabilities associated with the Pension
Plan as well as other postretirement employee benefit plans. As of December 31, 2005, the Pension Plan was amended to freeze
benefit plan accruals for the participants. The plan assets acquired and obligations assumed were recognized at fair value on the
Merger close date.

The objective for the investment portfolio of the Pension Plan is to achieve a long-term nominal rate of return, net of fees, that
exceeds the Pension Plan's long-term expected rate of return on investments for funding purposes. To meet this objective, our
investment strategy is governed by an asset allocation policy, whereby a targeted allocation percentage is assigned to each asset
class as follows: 41% to equities; 44% to fixed income investments; 11% to real estate, infrastructure and private assets; and
4% to other investments including hedge funds. Actual allocations are allowed to deviate from target allocation percentages
within a range for each asset class as defined in the investment policy. The long-term expected rate of return on plan assets was
5% and 4% for the years ended December 31, 2022 and 2021, respectively, while the actual rate of return on plan assets was
(14)% and 8% for the years ended December 31, 2022 and 2021, respectively. The long-term expected rate of return on
investments for funding purposes is 7% for the year ended December 31, 2023.

The components of net expense recognized for the Pension Plan were as follows:

The net expense associated with the Pension Plan is included in Other 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, 2022, 17% of the investment portfolio was valued at quoted prices in active
markets for identical assets, 79% was valued using quoted prices for similar assets in active or inactive markets, or other
observable inputs, and 4% was valued using unobservable inputs that are supported by little or no market activity. As of
December 31, 2021, 14% of the investment portfolio was valued at quoted prices in active markets for identical assets, 81%
was valued using quoted prices for similar assets in active or inactive markets, or other observable inputs, and 5% 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 $1.2 billion and
$1.5 billion as of December 31, 2022 and 2021, respectively. Certain investments, as a practical expedient, are reported at
estimated fair value, utilizing net asset values of $24 million as of December 31, 2022 which are part of our Plan assets. Our
accumulated benefit obligations in aggregate were $1.6 billion and $2.2 billion as of December 31, 2022 and 2021,

99

respectively. As a result, the plans were underfunded by approximately $342 million and $633 million as of December 31, 2022
and 2021, 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, 2022, and 2021, we used a weighted-average discount rate of 6% and 3%,
respectively.

During the years ended December 31, 2022 and 2021, we made contributions of $37 million and $83 million, respectively, to
the benefit plans. We expect to make contributions to the Plan of $32 million through the year ending December 31, 2023.

Future benefits expected to be paid are approximately $101 million for the year ending December 31, 2023, $210 million in
total for the years ending December 31, 2024 and 2025, $219 million in total for the years ending December 31, 2026 and 2027,
and $567 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 $175 million, $190 million and $179 million for the years ended December 31, 2022, 2021 and
2020, respectively.

Note 12 – Discontinued Operations

On July 26, 2019, we entered into an Asset Purchase Agreement with Sprint and DISH. On June 17, 2020, T-Mobile, Sprint and
DISH entered into the First Amendment. Pursuant to the First Amendment to the Asset Purchase Agreement, T-Mobile, Sprint
and DISH agreed to proceed with the closing of the Prepaid Transaction, in accordance with the Asset Purchase Agreement, on
July 1, 2020, subject to the terms and conditions of the Asset Purchase Agreement and the terms and conditions of the Consent
Decree.

On July 1, 2020, pursuant to the Asset Purchase Agreement, upon the terms and subject to the conditions thereof, we completed
the Prepaid Transaction. Upon closing of the Prepaid Transaction, we received $1.4 billion from DISH for the Prepaid
Business, subject to a working capital adjustment. The close of the Prepaid Transaction did not have a significant impact on our
Consolidated Statements of Comprehensive Income.

The results of the Prepaid Business include revenues and expenses directly attributable to the operations disposed. Corporate
and administrative expenses, including Interest expense, net, not directly attributable to the operations were not allocated to the
Prepaid Business. The results of the Prepaid Business from April 1, 2020, through December 31, 2020, are presented in Income
from discontinued operations, net of tax on our Consolidated Statements of Comprehensive Income. There was no income from
discontinued operations for the years ended December 31, 2022 or 2021.

The components of discontinued operations from the Merger close date of April 1, 2020, through December 31, 2020, were as

the year ended December 31, 2020, were $611 million, all of which relates to the operations of the Prepaid Business during the
three months ended June 30, 2020. There were no cash flows from investing or financing activities related to the Prepaid
Business for the year ended December 31, 2020.

Continuing Involvement

Upon the closing of the Prepaid Transaction, we and DISH entered into (i) a DISH License Purchase Agreement pursuant to
which (a) DISH has the option to purchase certain 800 MHz spectrum licenses for a total of approximately $3.6 billion in a
transaction to be completed, subject to certain additional closing conditions, following an application for FCC approval to be
filed three years following the closing of the Merger and (b) we will have the option to lease back from DISH, as needed, a
portion of the spectrum sold for an additional two years following the closing of the spectrum sale transaction, (ii) a Transition
Services Agreement providing for our provisioning of transition services to DISH in connection with the Prepaid Business for a
period of up to three years following the closing of the Prepaid Transaction, (iii) a Master Network Services Agreement
providing for the provisioning of network services to customers of the Prepaid Business for a period of up to seven years
following the closing of the Prepaid Transaction, and (iv) an Option to Acquire Tower and Retail Assets, offering DISH the
option to acquire certain decommissioned towers and retail locations from us, subject to obtaining all necessary third-party
consents, for a period of up to five years following the closing of the Prepaid Transaction.

In the event DISH breaches the DISH License Purchase Agreement or fails to deliver the purchase price following the
satisfaction or waiver of all closing conditions, DISH’s sole liability is to pay us a fee of approximately $72 million.
Additionally, if DISH does not exercise the option to purchase the 800 MHz spectrum licenses, we have an obligation to offer
the licenses for sale through an auction. If the specified minimum price of $3.6 billion was not met in the auction, we would
retain the licenses. As it is not probable that the sale of 800 MHz spectrum licenses will close within one year, the criteria for
presentation as an asset held for sale is not met.

Cash flows associated with the Master Network Services Agreement and Transition Services Agreement are included in Net
cash provided by operating activities on our Consolidated Statements of Cash Flows.

As of December 31, 2022, we have tax effected federal net operating loss (“NOL”) carryforwards of $5.6 billion, state NOL
carryforwards of $1.6 billion and foreign NOL carryforwards of $31 million, expiring through 2042. Federal and certain state
NOLs generated in and after 2018 do not expire. As of December 31, 2022, our tax effected federal and state NOL
carryforwards for financial reporting purposes were approximately $197 million and $444 million, respectively, less than our
NOL carryforwards for federal and state income tax purposes, due to unrecognized tax benefits of the same amount. There were
no differences in our foreign NOL carryforwards for financial reporting purposes and our NOL carryforwards for foreign
income tax purposes as of December 31, 2022. The unrecognized tax benefit amounts exclude offsetting tax effects of $132
million in other jurisdictions.

As of December 31, 2022, we have research and development, foreign tax and other general business credit carryforwards with
a combined value of $704 million for federal income tax purposes, an immaterial amount of which begins to expire in 2023.

As of December 31, 2022, 2021 and 2020, our valuation allowance was $375 million, $435 million and $878 million,
respectively. The change from December 31, 2021 to December 31, 2022 primarily related to a reduction in the valuation
allowance against deferred tax assets in certain foreign jurisdictions resulting from legal entity reorganizations. The change
from December 31, 2020 to December 31, 2021 primarily related to a reduction in the valuation allowance against deferred tax

102

assets in certain state jurisdictions resulting from legal entity reorganizations of legacy Sprint entities. It is possible that our
valuation allowance may change within the next 12 months.

We file income tax returns in the U.S. federal jurisdiction and in various state and foreign jurisdictions. We are currently under
examination by the IRS and 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 its audits of our federal
tax returns through the 2009 tax year; however, NOL and other carryforwards for certain audited periods remain open for
examination. U.S. federal, state and foreign examination for years prior to 2003 are generally closed.

A reconciliation of the beginning and ending amount of unrecognized tax benefits were as follows:

(in millions)

Unrecognized tax benefits, beginning of year

Gross increases to tax positions in prior periods

Gross decreases to tax positions in prior periods

Gross increases to current period tax positions

Gross increases due to current period business acquisitions

tax benefits that, if recognized, would affect our annual effective tax rate. Penalties and interest on income tax assessments are
included in Selling, general and administrative and Interest expense, respectively, on our Consolidated Statements of
Comprehensive Income. The accrued interest and penalties associated with unrecognized tax benefits are insignificant. It is
possible that the amount of unrecognized tax benefits related to our uncertain tax positions may change within the next 12

Note 14 – SoftBank Equity Transaction

On June 22, 2020, we entered into a Master Framework Agreement (the “Master Framework Agreement”) by and among the
Company, SoftBank, SoftBank Group Capital Ltd, a wholly owned subsidiary of SoftBank (“SBGC”), Delaware Project 4
L.L.C., a wholly owned subsidiary of SoftBank, Delaware Project 6 L.L.C., a wholly owned subsidiary of SoftBank, Claure
Mobile LLC (“CM LLC”), DT, and T-Mobile Agent LLC, a wholly owned subsidiary of the Company.

In connection with the Master Framework Agreement, DT waived the restriction on the transfer under its Proxy, Lock-Up and
ROFR Agreement, dated April 1, 2020, with SoftBank (the “SoftBank Proxy Agreement”) with respect to approximately 198
million shares of our common stock held by SoftBank (the “Released Shares”). Under the terms of the Master Framework
Agreement and the agreements contemplated thereby, SBGC sold the Released Shares to us and we entered into several
transactions to sell an equivalent number of our common shares (the “SoftBank Monetization”). In 2020, we settled our
involvement with all such transactions with no net impact to our Consolidated Statements of Comprehensive Income and we
received a payment from SoftBank for $304 million for our role in facilitating the SoftBank Monetization. The payment
received from SoftBank, net of tax, of $230 million was recorded as Additional paid-in capital on our Consolidated Balance
Sheets and is presented as a reduction of Repurchases of common stock in Net cash (used in) provided by financing activities
on our Consolidated Statements of Cash Flows.

Ownership Following the SoftBank Monetization

The SoftBank Proxy Agreement remains in effect with respect to the remaining shares of our common stock held by SoftBank
and any SoftBank Specified Shares Amount that may be issued to SoftBank. In addition, on June 22, 2020, DT, CM LLC, and
Marcelo Claure, a member of our board of directors, entered into a Proxy, Lock-Up and ROFR Agreement (the “Claure Proxy
Agreement,” together with the SoftBank Proxy Agreement, the “Proxy Agreements”), pursuant to which any shares of our
common stock acquired after June 22, 2020 by Mr. Claure or CM LLC, an entity controlled by Mr. Claure, other than shares
acquired as a result of Mr. Claure’s role as a director or officer of the Company, will be voted in the manner as directed by DT.

103

As of December 31, 2022, DT and SoftBank held, directly or indirectly, approximately 49.0% and 3.2%, respectively, of the
outstanding T-Mobile common stock, with the remaining approximately 47.8% of the outstanding T-Mobile common stock
held by other stockholders.

Accordingly, as a result of the Proxy Agreements, DT has voting control as of December 31, 2022 over approximately 52.7% of
the outstanding T-Mobile common stock.

Note 15 – Repurchases of Common Stock

2022 Stock Repurchase Program

On September 8, 2022, our Board of Directors authorized our 2022 Stock Repurchase Program for up to $14.0 billion of our
common stock through September 30, 2023. Under the 2022 Stock Repurchase Program, repurchases can be made from time to
time using a variety of methods, which may include open market purchases, 10b5-1 plans, privately negotiated transactions or
other methods. The specific timing, price and size of repurchases will depend on prevailing stock prices, general economic and
market conditions, and other considerations. The 2022 Stock Repurchase Program does not obligate us to acquire any particular
amount of common stock, and the 2022 Stock Repurchase Program may be suspended or discontinued at any time at our
discretion. Repurchased shares will be held as Treasury stock on our Consolidated Balance Sheets.

During the year ended December 31, 2022, we repurchased 21,361,409 shares of our common stock at an average price per
share of $140.44 for a total purchase price of $3.0 billion, all of which were purchased under the 2022 Stock Repurchase
Program. All shares purchased during the year ended December 31, 2022, were purchased at market price. As of December 31,
2022, we had up to $11.0 billion remaining under the 2022 Stock Repurchase Program.

Subsequent to December 31, 2022, from January 1, 2023 through February 10, 2023, we repurchased 14,676,718 shares of our
common stock at an average price per share of $145.70 for a total purchase price of $2.1 billion. As of February 10, 2023, we
had up to $8.9 billion remaining under the 2022 Stock Repurchase Program.

Note 16 – Wireline

Sale of the Wireline Business

On September 6, 2022, two of our wholly owned subsidiaries, Sprint Communications and Sprint LLC, and Cogent
Infrastructure, Inc., entered into the Wireline Sale Agreement, pursuant to which the Buyer will acquire the Wireline Business.
The Wireline Sale Agreement provides that, upon the terms and conditions set forth therein, the Buyer will purchase all of the
issued and outstanding membership interests (the “Purchased Interests”) of a Delaware limited liability company that holds
certain assets and liabilities relating to the Wireline Business.

The parties have agreed to a $1 purchase price in consideration for the Purchased Interests, subject to customary adjustments set
forth in the Wireline Sale Agreement. In addition, at the consummation of the Wireline Transaction (the “Closing”), a T-Mobile
affiliate will enter into a commercial agreement for IP transit services, pursuant to which T-Mobile will pay to the Buyer an
aggregate of $700 million, consisting of (i) $350 million in equal monthly installments during the first year after the Closing
and (ii) $350 million in equal monthly installments over the subsequent 42 months. The Closing is subject to customary closing
conditions, including the receipt of certain required regulatory approvals and consents. Subject to the satisfaction or waiver of
certain conditions and other terms and conditions of the Wireline Sale Agreement, the Wireline Transaction is expected to close
mid-year 2023.

As a result of the Wireline Sale Agreement and related anticipated Wireline Transaction, we concluded that the Wireline
Business met the held for sale criteria upon entering into the Wireline Sale Agreement. As such, the assets and liabilities of the
Wireline Business disposal group are classified as held for sale and presented within Other current assets and Other current
liabilities on our Consolidated Balance Sheets as of December 31, 2022.

The components of assets and liabilities held for sale presented within Other current assets and Other current liabilities,
respectively, on our Consolidated Balance Sheets as of December 31, 2022, were as follows:

Wireline Transaction.

In connection with the expected sale of the Wireline Business and classification of related assets and liabilities as held for sale,
we recognized a pre-tax loss of $1.1 billion during the year ended December 31, 2022, which is included within Loss on
disposal group held for sale on our Consolidated Statements of Comprehensive Income.

The components of the Loss on disposal group held for sale on our Consolidated Statements of Comprehensive Income for the
year ended December 31, 2022, were as follows:

(1) We will continue to recognize accretion expense through the expiration of the agreement which will be included in Interest expense, net separate from the

Loss on disposal group held for sale on our Consolidated Statements of Comprehensive Income.

The present value of the liability for fees payable for IP transit services has been recognized as a component of Loss on disposal
group held for sale as we have not currently identified any path to utilize such services in our continuing operations and have
committed to execute the agreement as a closing condition for the Wireline Transaction. We will continue to evaluate potential
uses on an ongoing basis over the life of the agreement. Approximately $117 million and $531 million of this liability,
including accrued interest, is presented within Other current liabilities and Other long-term liabilities, respectively, on our
Consolidated Balance Sheets as of December 31, 2022, in accordance with the expected timing of the related payments.
Approximately $30 million and $35 million for contractual and other payments associated with the Wireline Transaction are
presented within Other current liabilities and Other long-term liabilities, respectively, on our Consolidated Balance Sheets as of
December 31, 2022, in accordance with the expected timing of the related payments.

We do not consider the sale of the Wireline Business to be a strategic shift that will have a major effect on the Company’s
operations and financial results, and therefore it does not qualify for reporting as a discontinued operation.

105

Other Wireline Asset Sales

Separate from the Wireline Transaction, we recognized a gain on disposal of $121 million during the year ended December 31,
2022, all of which relates to the sale of certain IP addresses held by the Wireline Business to other third parties during the three
months ended September 30, 2022. The gain on disposal is included as a reduction to Selling, general and administrative
expenses on our Consolidated Statements of Comprehensive Income.

Wireline Impairment

We provide wireline communication services to domestic and international customers via the legacy Sprint Wireline U.S. long-
haul fiber network (including non-U.S. extensions thereof) acquired through the Merger. The legacy Sprint Wireline network is
primarily comprised of owned property and equipment, including land, buildings, communication systems and data processing
equipment, fiber optic cable and operating lease right-of-use assets. Previously, the operation of the legacy Sprint CDMA and
LTE wireless networks was supported by the legacy Sprint Wireline network. During the second quarter of 2022, we retired the
legacy Sprint CDMA network and began the orderly shut-down of the LTE network.

We assess long-lived assets for impairment when events or circumstances indicate that they might be impaired. During the
second quarter of 2022, we determined that the retirement of the legacy Sprint CDMA and LTE wireless networks triggered the
need to assess the Wireline long-lived assets for impairment, as these assets no longer support our wireless network and the
associated customers and cash flows in a significant manner. In evaluating whether the Wireline long-lived assets were
impaired, we estimated the fair value of these assets using a combination of the cost, income and market approaches, including
market participant assumptions. The fair value measurement of the Wireline assets was estimated using significant inputs not
observable in the market (Level 3).

The results of this assessment indicated that certain Wireline long-lived assets were impaired, and as a result, we recorded non-
cash impairment expense of $477 million during the year ended December 31, 2022, all of which relates to the impairment
recognized during the three months ended June 30, 2022, of which $258 million is related to Wireline Property and equipment,
$212 million is related to Operating lease right-of-use assets and $7 million is related to Other intangible assets. In measuring
and allocating the impairment expense to individual Wireline long-lived assets, we did not impair the long-lived assets below
their individual fair values. The expense is included within Impairment expense on our Consolidated Statements of
Comprehensive Income.

As of December 31, 2022, we had authorized 100 million shares of preferred stock, with a par value of $0.00001 per share.
There was no preferred stock outstanding as of December 31, 2022 and 2021. Potentially dilutive securities were not included
in the computation of diluted earnings per share if to do so would have been anti-dilutive.

The SoftBank Specified Shares Amount of 48,751,557 shares of T-Mobile common stock was determined to be contingent

Note 18 – Leases

Lessee

We are a lessee for non-cancelable operating and financing leases for cell sites, switch sites, retail stores, network equipment
and office facilities with contractual terms that generally extend through 2035. Additionally, we lease dark fiber through non-
cancelable operating leases with contractual terms that generally extend through 2040. The majority of cell site leases have a
non-cancelable term of five to 15 years with several renewal options that can extend the lease term for five to 50 years. In
addition, we have financing leases for network equipment that generally have a non-cancelable lease term of three to five years.
The financing leases do not have renewal options and contain a bargain purchase option at the end of the lease.

On January 3, 2022, we entered into the Crown Agreement with CCI that modified the terms of our leased towers from CCI.
The Crown Agreement modifies the monthly rental payments we will pay for sites currently leased by us, extends the non-
cancellable lease term for the majority of our sites through December 2033 and will allow us the flexibility to facilitate our
network integration and decommissioning activities through new site builds and termination of duplicate tower locations. The
initial non-cancellable term is through December 31, 2033, followed by three optional five-year renewals. As a result of this
modification, we remeasured the associated right-of use assets and lease liabilities resulting in an increase of $5.3 billion to
each on the effective date of the modification, with a corresponding gross increase to both deferred tax liabilities and assets of
$1.3 billion.

During the second quarter of 2022, we determined that the retirement of the legacy Sprint CDMA and LTE wireless networks

indicated that certain Wireline property and equipment was impaired. See Note 16 - Wireline for further information.

Note 19 – Commitments and Contingencies

Purchase Commitments

We have commitments for non-dedicated transportation lines with varying expiration terms that generally extend through 2038.
In addition, we have commitments to purchase wireless devices, network services, equipment, software, marketing sponsorship
agreements and other items in the ordinary course of business, with various terms through 2043.

Our purchase commitments are approximately $4.5 billion for the 12-month period ending December 31, 2023, $4.9 billion in
total for both of the 12-month periods ending December 31, 2024 and 2025, $2.8 billion in total for both of the 12-month
periods ending December 31, 2026 and 2027, and $2.8 billion in total thereafter. 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.

Spectrum Leases

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 $315 million for the 12-
month period ending December 31, 2023, $587 million in total for both of the 12-month periods ending December 31, 2024 and
2025, $634 million in total for both of the 12-month periods ending December 31, 2026 and 2027, and $4.6 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 $3.5 billion. The agreements remain
subject to regulatory approval and are excluded from our reported commitments above. See Note 6 – Goodwill, Spectrum
License Transactions and Other Intangible Assets for additional details.

Contingencies and Litigation

Litigation and Regulatory Matters

We are involved in various lawsuits and disputes, claims, government agency investigations and enforcement actions, and other
proceedings (“Litigation and Regulatory Matters”) that arise in the ordinary course of business, which include claims of patent
infringement (most of which are asserted by non-practicing entities primarily seeking monetary damages), class actions, and
proceedings to enforce FCC or other government agency rules and regulations. Those Litigation and Regulatory Matters are at
various stages, and some of them may proceed to trial, arbitration, hearing, or other adjudication that could result in fines,
penalties, or awards of monetary or injunctive relief in the coming 12 months if they are not otherwise resolved. We have
established an accrual with respect to certain of these matters, where appropriate. The accruals are reflected on our consolidated

109

financial statements, but they are not considered to be, individually or in the aggregate, material. An accrual is established when
we believe it is both probable that a loss has been incurred and an amount can be reasonably estimated. For other matters, where
we have not determined that a loss is probable or because the amount of loss cannot be reasonably estimated, we have not
recorded an accrual due to various factors typical in contested proceedings, including, but not limited to, uncertainty concerning
legal theories and their resolution by courts or regulators, uncertain damage theories and demands, and a less than fully
developed factual record. For Litigation and Regulatory Matters that may result in a contingent gain, we recognize such gains
on our consolidated financial statements when the gain is realized or realizable. We recognize legal costs expected to be
incurred in connection with Litigation and Regulatory Matters as they are incurred. Except as otherwise specified below, we do
not expect that the ultimate resolution of these Litigation and Regulatory Matters, individually or in the aggregate, will have a
material adverse effect on our financial position, but we note that an unfavorable outcome of some or all of the specific matters
identified below or other matters that we are or may become involved in could have a material adverse impact on results of
operations or cash flows for a particular period. This assessment is based on our current understanding of relevant facts and
circumstances. As such, our view of these matters is subject to inherent uncertainties and may change in the future.

On February 28, 2020, we received a Notice of Apparent Liability for Forfeiture and Admonishment from the FCC, which
proposed a penalty against us for allegedly violating section 222 of the Communications Act and the FCC’s regulations
governing the privacy of customer information. In the first quarter of 2020, we recorded an accrual for an estimated payment
amount. We maintained the accrual as of December 31, 2022, and that accrual was included in Accounts payable and accrued
liabilities on our Consolidated Balance Sheets.

On April 1, 2020, in connection with the closing of the Merger, we assumed the contingencies and litigation matters of Sprint.
Those matters include a wide variety of disputes, claims, government agency investigations and enforcement actions, and other
proceedings. These matters include, among other things, certain ongoing FCC and state government agency investigations into
Sprint’s Lifeline program. In September 2019, Sprint notified the FCC that it had claimed monthly subsidies for serving
subscribers even though these subscribers may not have met usage requirements under Sprint's usage policy for the Lifeline
program, due to an inadvertent coding issue in the system used to identify qualifying subscriber usage that occurred in July
2017 while the system was being updated. Sprint has made a number of payments to reimburse the federal government and
certain states for excess subsidy payments.

We note that pursuant to Amendment No. 2, dated as of February 20, 2020, to the Business Combination Agreement, SoftBank
agreed to indemnify us against certain specified matters and losses, including those relating to the Lifeline matters described
above. Resolution of these matters could require making additional reimbursements and paying additional fines and penalties,
which we do not expect to have a significant impact on our financial results. We expect that any additional liabilities related to
these indemnified matters would be indemnified and reimbursed by SoftBank.

On June 1, 2021, a putative shareholder class action and derivative lawsuit was filed in the Delaware Court of Chancery,
Dinkevich v. Deutsche Telekom AG, et al., Case No. C.A. No. 2021-0479, against DT, SoftBank and certain of our current and
former officers and directors, asserting breach of fiduciary duty claims relating to the repricing amendment to the Business
Combination Agreement, and to SoftBank’s monetization of its T-Mobile shares. We are also named as a nominal defendant in
the case. We are unable to predict the potential outcome of these claims.

In October 2020, we notified Mobile Virtual Network Operators (“MVNOs”) using the legacy Sprint CDMA network that we
planned to retire that network on December 31, 2021. In response to that notice, DISH, which had Boost Mobile customers who
used the legacy Sprint CDMA network, made several efforts to prevent us from retiring the CDMA network until mid-2023,
including pursuing a Petition for Modification and related proceedings pursuant to the California Public Utilities Commission’s
(the “CPUC”) April 2020 decision concerning the Merger. As of June 30, 2022, the orderly decommissioning of the legacy
Sprint CDMA network had been completed, although certain of the CPUC proceedings remain in process.

On August 12, 2021, we became aware of a cybersecurity issue involving unauthorized access to T-Mobile’s systems (the
“August 2021 cyberattack”). We immediately began an investigation and engaged cybersecurity experts to assist with the
assessment of the incident and to help determine what data was impacted. Our investigation uncovered that the perpetrator had
illegally gained access to certain areas of our systems on or about March 18, 2021, but only gained access to and took data of
current, former, and prospective customers beginning on or about August 3, 2021. With the assistance of our outside
cybersecurity experts, we located and closed the unauthorized access to our systems and identified current, former and
prospective customers whose information was impacted and notified them, consistent with state and federal requirements. We
also undertook a number of other measures to demonstrate our continued support and commitment to data privacy and
protection. We also coordinated with law enforcement. Our forensic investigation is complete, and we believe we have a full
view of the data compromised.

110

As a result of the August 2021 cyberattack, we have become subject to numerous lawsuits, including mass arbitration claims
and multiple class action lawsuits that have been filed in numerous jurisdictions seeking, among other things, unspecified
monetary damages, costs and attorneys’ fees arising out of the August 2021 cyberattack. In December 2021, the Judicial Panel
on Multidistrict Litigation consolidated the federal class action lawsuits in the U.S. District Court for the Western District of
Missouri under the caption In re: T-Mobile Customer Data Security Breach Litigation, Case No. 21-md-3019-BCW. On July
22, 2022, we entered into an agreement to settle the lawsuit. On July 26, 2022, we received preliminary approval of the
proposed settlement, which remains subject to final court approval. The court conducted a final approval hearing on January 20,
2023, and we await a ruling from the court. If approved by the court, under the terms of the proposed settlement, we would pay
an aggregate of $350 million to fund claims submitted by class members, the legal fees of plaintiffs’ counsel and the costs of
administering the settlement. We would also commit to an aggregate incremental spend of $150 million for data security and
related technology in 2022 and 2023. We anticipate that, upon court approval, the settlement will provide a full release of all
claims arising out of the August 2021 cyberattack by class members, who do 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 have the right to terminate the settlement agreement under certain conditions.

If approved by the court, 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 proposed
class action settlement and the separate settlements, we recorded a total pre-tax charge of approximately $400 million during
the three months ended June 30, 2022. The expense is included within Selling, general and administrative expenses on our
Consolidated Statements of Comprehensive Income. During the year ended December 31, 2022, we recognized $100 million 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. The
ultimate resolution of the class action depends on whether we will be able to obtain court approval of the proposed settlement,
the number of plaintiffs who opt-out of the proposed settlement and whether the proposed settlement will be appealed.

In addition, in September 2022, a purported Company shareholder filed a derivative action in the Delaware Chancery Court
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. 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 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 are responding to these inquiries and
cooperating fully with these agencies and regulators. However, 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, 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.

In 2022, we received $333 million in gross settlements of certain patent litigation assumed in the Merger. We recognized these
settlements, net of legal fees, as a reduction to Selling, general and administrative expenses on our Consolidated Statements of
Comprehensive Income during the year ended December 31, 2022.

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 who plaintiffs allege paid artificially inflated
prices due to the Merger. We intend to vigorously defend this lawsuit, but we are unable to predict the potential outcome.

On January 5, 2023, we identified that a bad actor was obtaining data through a single API without authorization. Based on our
investigation to date, the impacted API is only able to provide a limited set of customer account data, including name, billing
address, email, phone number, date of birth, T-Mobile account number and information such as the number of lines on the
account and plan features. The result from our investigation to date indicates that the bad actor(s) obtained data from this API

111

for approximately 37 million current postpaid and prepaid customer accounts, though many of these accounts did not include
the full data set. We believe that the bad actor first retrieved data through the impacted API starting on or around November 25,
2022. We continue to investigate the incident and have notified individuals whose information was impacted consistent with
state and federal requirements.

In connection with the January 2023 cyberattack, we have received notices of consumer class actions and regulatory inquires, to
which we will respond to 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.

Note 20 – Restructuring Costs

Upon close of the Merger, we began implementing restructuring initiatives to realize cost efficiencies and reduce redundancies.
The major activities associated with the Merger restructuring initiatives to date include contract termination costs associated
with the rationalization of retail stores, distribution channels, duplicative network and backhaul services and other agreements,
severance costs associated with the integration of redundant processes and functions and the decommissioning of certain small
cell sites and distributed antenna systems to achieve Merger synergies in network costs.

The following table summarizes the expenses incurred in connection with our Merger restructuring initiatives:

The expenses associated with our Merger restructuring initiatives are included in Costs of services and Selling, general and
administrative on our Consolidated Statements of Comprehensive Income.

Our Merger restructuring initiatives also include the acceleration or termination of certain of our operating and financing leases
for cell sites, switch sites, retail stores, network equipment and office facilities. Incremental expenses associated with
accelerating amortization of the right-of-use assets on lease contracts were $1.7 billion, $873 million and $153 million for the
years ended December 31, 2022, 2021 and 2020, respectively, and are included in Costs of services and Selling, general and
administrative on our Consolidated Statements of Comprehensive Income.

Our Merger restructuring activities are expected to occur over the next year with substantially all costs incurred by the end of
fiscal year 2023, with the related cash outflows extending beyond 2023. We continue to evaluate additional restructuring
initiatives, which are dependent on consultations and negotiation with certain counterparties and the expected impact on our
business operations, which could affect the amount or timing of the restructuring costs and related payments.

Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure

None.

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.

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, 2022.

The effectiveness of our internal control over financial reporting as of December 31, 2022 has been audited by Deloitte &
Touche LLP, an independent registered public accounting firm, as stated in their report herein.
