Notes to the Condensed Consolidated Financial Statements

Note 1 – Summary of Significant Accounting Policies

Basis of Presentation

The unaudited condensed consolidated financial statements of T-Mobile US, Inc. (“T-Mobile,” “we,” “our,” “us” or the “Company”) include all adjustments of a normal recurring nature necessary for the fair presentation of the results for the interim periods presented. The results for the interim periods are not necessarily indicative of those for the full year. The condensed consolidated financial statements should be read in conjunction with our consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2020.

The condensed 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 our obligations to pay for the management and operation of certain of our wireless communications tower sites. Intercompany transactions and balances have been eliminated in consolidation.

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

Accounting Pronouncements Not Yet Adopted

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” (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, 2022, and the optional expedients for contract modifications must be elected for all arrangements within a given Accounting Standards Codification (“ASC”) Topic or Industry Subtopic. We expect to elect the optional expedients for eligible contract modifications accounted for under a given ASC Topic as they occur through December 31, 2022. The application of these expedients is not expected to have a material impact on our consolidated financial statements.

Other recent accounting pronouncements issued by the FASB (including its Emerging Issues Task Force), the American Institute of Certified Public Accountants, and the U.S. Securities and Exchange Commission did not have, or are not expected to have, a significant impact on our present or future 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. As of September 30, 2021, DT and SoftBank held, directly or indirectly, approximately 46.8% and 4.9%, respectively, of the outstanding T-Mobile common stock, with the remaining approximately 48.3% of the outstanding T-Mobile common stock held by other stockholders. Pursuant to the Proxy, Lock-up and ROFR Agreement, dated as of April 1, 2020, by and between DT and SoftBank and the Proxy, Lock-up and ROFR Agreement, dated as of June 22, 2020 by and among DT, Marcelo Claure and Claure Mobile LLC, a Delaware limited liability company wholly owned by Mr. Claure, as of September 30, 2021, DT has voting control over approximately 52.0% of the outstanding T-Mobile common stock.

Consideration Transferred

The acquisition-date fair value of consideration transferred in the Merger totaled $40.8 billion, comprised of the following:


(in millions)	April 1, 2020
Fair value of T-Mobile common stock issued to Sprint stockholders (1)	$	31,328
Fair value of T-Mobile replacement equity awards attributable to pre-combination service (2)	323
Repayment of Sprint’s debt (including accrued interest and prepayment penalties) (3)	7,396

Fair value of contingent consideration (4)	1,882
Payment received from selling stockholder (5)	(102)
Total consideration exchanged	$	40,827

(1) Represents the fair value of T-Mobile common stock issued to Sprint stockholders pursuant to the Business Combination Agreement, less shares surrendered by SoftBank pursuant to the Letter Agreement. The fair value is based on 373,396,310 shares of T-Mobile common stock issued at an

Index for Notes to the Condensed Consolidated Financial Statements

exchange ratio of 0.10256 shares of T-Mobile common stock per share of Sprint common stock, less 48,751,557 T-Mobile shares surrendered by SoftBank which are treated as contingent consideration, and the closing price per share of T-Mobile common stock on NASDAQ on March 31, 2020, of $83.90, as shares were transferred to Sprint stockholders prior to the opening of markets on April 1, 2020.

(2) Equity-based awards held by Sprint employees prior to the acquisition date have been replaced with T-Mobile equity-based awards. The portion of the 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.

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.

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.

Index for Notes to the Condensed Consolidated Financial Statements

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 Equipment installment plan (“EIP”) receivables of $1.3 billion. The unpaid principal balance 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 unpaid principal balance 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 Federal Communications Commission (“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.

Transaction Costs

We recognized transaction costs of $15 million and $8 million for the three months ended September 30, 2021 and 2020, respectively, and $28 million and $192 million for the nine months ended September 30, 2021 and 2020, respectively. These costs were associated with legal and professional services and were recognized as Selling, general and administrative expenses in our Condensed Consolidated Statements of Comprehensive Income.

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 Combinations, which is a different basis than pro forma information prepared under Article 11 of Regulation S-X (“Article 11”). As such, they are not directly comparable with historical results for stand-alone T-Mobile prior to April 1, 2020, historical results for T-Mobile from April 1, 2020 that reflect the Transactions and are inclusive of the results and operations of Sprint, nor our previously provided pro forma financials prepared in accordance with Article 11. The pro forma results for the three and nine months ended September 30, 2020 include the impact of several significant nonrecurring pro forma adjustments to previously reported operating results. The pro forma adjustments are based on historically reported transactions by the respective companies. The pro forma results do not include any anticipated synergies or other expected benefits of the acquisition.

•Tangible and intangible assets are assumed to be recorded at their estimated fair values as of January 1, 2019 and are depreciated or amortized over their estimated useful lives; and

•Accounting policies of Sprint are conformed to those of T-Mobile including depreciation for leased devices, distribution arrangements with Brightstar US, Inc., amortization of costs to acquire a contract and certain tower lease transactions.

The selected unaudited pro forma condensed combined financial information is provided for illustrative purposes only and does not purport to represent what the actual consolidated results of operations would have been had the Transactions actually occurred on January 1, 2019, nor do they purport to project the future consolidated results of operations.

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 1 3 - Commitments and Contingencies 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 Shenandoah Personal Communications Company LLC (“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 telecommunications assets (the “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.

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.

Index for Notes to the Condensed Consolidated Financial Statements

Prior to the acquisition of the Wireless Assets, revenues generated from our affiliate relationship with Shentel were presented as Other service revenues. Upon the close of the transaction, revenues generated from postpaid customers within the reacquired territory are presented as Postpaid revenues within our Condensed Consolidated Statements of Comprehensive Income. The financial results of the Wireless Assets since the closing through September 30, 2021, were not material to our Condensed 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 have accounted for the acquisition of the Wireless Assets as a business combination. The identifiable assets acquired and liabilities assumed were recorded at their preliminary 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 preliminary 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 preliminary 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. We are in the process of finalizing the valuation of the assets acquired and liabilities assumed, including income tax related amounts. Therefore, the preliminary fair values set forth below are subject to further adjustment as additional information is obtained and the valuations are completed.

Short-term operating lease liabilities	73


Operating lease liabilities	264
Other long-term liabilities	35
Total liabilities assumed	372
Total consideration transferred	$	1,886

Intangible Assets and Liabilities

Goodwill with a provisionally 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 re-acquisition 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 Expected Credit Losses

We maintain an allowance for expected credit losses that assesses the lifetime credit losses that we expect to incur related to our receivable portfolio segments. 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.

Index for Notes to the Condensed Consolidated Financial Statements

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, 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 2 portfolio segments: accounts receivable and EIP receivables.

Accounts Receivable Portfolio Segment

Our accounts receivable segment primarily consists of amounts currently due from customers, including service and leased device receivables, device insurance administrators, wholesale partners, third-party retail channels and other carriers.

We estimate expected credit losses associated with our accounts receivable portfolio using an aging schedule methodology that utilizes historical information and current conditions to develop expected credit losses by aging bucket, including for receivables that are not past due.

To determine the appropriate credit loss percentages by aging bucket, we consider a number of factors, including our overall historical credit losses, net of recoveries and timely payment experience as well as current collection trends such as write-off frequency and severity, credit quality of the customer base, and other qualitative factors such as macro-economic conditions, including the expected economic impacts of the COVID-19 pandemic (the “Pandemic”).

We consider the need to adjust our estimate of expected credit losses for reasonable and supportable forecasts of future economic conditions. To do so, we monitor professional 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 economic 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 2 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. In addition, certain customers within the Subprime category may be required to pay a deposit.

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

Installment loans 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.

The following table summarizes the EIP receivables, including imputed discounts and related allowance for credit losses:


(in millions)	September 30, 2021		December 31, 2020


EIP receivables, gross	$	7,164	$	6,213
Unamortized imputed discount	(330)		(325)

EIP receivables, net of unamortized imputed discount	6,834		5,888
Allowance for credit losses	(248)		(280)

EIP receivables, net of allowance for credit losses and imputed discount	$	6,586	$	5,608
Classified on the balance sheet as:
Equipment installment plan receivables, net of allowance for credit losses and imputed discount	$	4,306	$	3,577
Equipment installment plan receivables due after one year, net of allowance for credit losses and imputed discount	2,280		2,031

EIP receivables, net of allowance for credit losses and imputed discount	$	6,586	$	5,608

Index for Notes to the Condensed Consolidated Financial Statements

We manage our EIP receivables portfolio 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 origination as of September 30, 2021:


	Originated in 2021				Originated in 2020				Originated prior to 2020				Total EIP Receivables, net of unamortized imputed discounts

We estimate expected credit losses on our EIP receivables by using historical data adjusted for current conditions to calculate default probabilities for our outstanding EIP loans. We consider various risk characteristics when calculating default probabilities, such as how long such loans have been outstanding, customer credit ratings, customer tenure, delinquency status and other correlated variables identified through statistical analyses. We multiply these estimated default probabilities by our estimated loss given default, which considers recoveries.

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

For EIP receivables acquired in the Merger, the difference between the fair value and unpaid principal balance of the loan at the acquisition date is accreted to interest income over the contractual life of the loan using the effective interest method. EIP receivables had a combined weighted average effective interest rate of 6.1% and 6.7% as of September 30, 2021 and December 31, 2020, respectively.

Activity for the nine months ended September 30, 2021 and 2020, in the allowance for credit losses and unamortized imputed discount balances for the accounts receivable and EIP receivables segments were as follows:


	September 30, 2021						September 30, 2020
(in millions)	Accounts Receivable Allowance		EIP Receivables Allowance		Total		Accounts Receivable Allowance		EIP Receivables Allowance		Total

Off-Balance-Sheet Credit Exposures

We do not have material, unmitigated off-balance-sheet credit exposures as of September 30, 2021. In connection with the sales of certain service and EIP accounts receivable pursuant to the sale arrangements, we have deferred purchase price assets included in our Condensed 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.

Index for Notes to the Condensed Consolidated Financial Statements

Note 4 – Sales of Certain Receivables

We have entered 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 condensed 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 sale arrangement is $1.3 billion. The scheduled expiration date of the EIP sale arrangement is November 18, 2021.

As of both September 30, 2021 and December 31, 2020, 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, our wholly owned subsidiary transfers selected receivables to the EIP BRE. The EIP BRE then sells the receivables to a non-consolidated and unaffiliated third-party entity over which we do not exercise any level of control, nor does the third-party entity qualify as a VIE.

Variable Interest Entity

We determined that the EIP BRE is a VIE as its equity investment at risk lacks the obligation to absorb a certain portion of its expected losses. We have a variable interest in the EIP BRE and have determined that we are the primary beneficiary based on our ability to direct the activities 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 in our condensed consolidated financial statements.

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


(in millions)	September 30, 2021		December 31, 2020
Other current assets	$	388	$	388
Other assets	170		120
Other long-term liabilities	3		4

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 March 2022. As of September 30, 2021 and December 31, 2020, the service receivable sale arrangement provided funding of $775 million and $772 million, respectively. 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”). In March 2021, we amended the sale arrangement to conform its structure to the EIP sale arrangement (the “March 2021 Amendment”). This involved, among other things, removal of an unaffiliated special purpose entity that we did not consolidate under the original structure and changes in

Index for Notes to the Condensed Consolidated Financial Statements

contractual counterparties. While the amendment simplified the structure of the arrangement making it more efficient, it did not impact the maximum funding commitment under, or the level of funding provided by, the facility.

Pursuant to the amended service receivable sale arrangement, our wholly owned subsidiary transfers selected receivables to the Service BRE. The Service BRE then sells the receivables to a non-consolidated and unaffiliated third-party entity over which we do not exercise any level of control and which does not qualify as a VIE.

Variable Interest Entity

Prior to the March 2021 Amendment, 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.

The March 2021 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 in our condensed consolidated financial statements.


(in millions)	September 30, 2021		December 31, 2020
Other current assets	$	207	$	378

Other current liabilities	344		357

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 in our Condensed 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 in our Condensed 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 in our Condensed 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 September 30, 2021 and December 31, 2020, our deferred purchase price related to the sales of service receivables and EIP receivables was $764 million and $884 million, respectively.

Index for Notes to the Condensed Consolidated Financial Statements

The following table summarizes the impact of the sale of certain service receivables and EIP receivables in our Condensed Consolidated Balance Sheets:

We recognized a loss from sales of receivables, including adjustments to the receivables’ fair values and changes in fair value of the deferred purchase price, of $4 million and a gain of $18 million, respectively, for the three months ended September 30, 2021 and 2020, respectively, and a gain of $26 million and a loss of $37 million for the nine months ended September 30, 2021 and 2020, respectively, in Selling, general and administrative expense in our Condensed Consolidated Statements of Comprehensive Income.

Continuing Involvement

Pursuant to the sale arrangements described above, we have continuing involvement with the service receivables and EIP receivables we sell as we service the receivables, are required to repurchase certain receivables, including ineligible receivables, aged receivables and receivables where 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. Pursuant to the EIP sale arrangement, under certain circumstances, we are required to deposit cash or replacement EIP receivables primarily for contracts terminated by customers under our JUMP! program.

Note 5 – Goodwill, Spectrum License Transactions and Other Intangible Assets

Goodwill

The changes in the carrying amount of goodwill for the nine months ended September 30, 2021, and the year ended December 31, 2020, are as follows:


(in millions)	Goodwill

Balance as of December 31, 2019, net of accumulated impairment losses of $10,766	$	1,930
Goodwill from acquisitions in 2020	9,405

On April 1, 2020, we completed the Merger, which was accounted for as a business combination resulting in $9.4 billion in goodwill. The acquired goodwill was allocated to the wireless reporting unit and will be tested for impairment at this level. See Note 2 - Business Combinations for further information.

On July 1, 2021, we completed our acquisition of the Wireless Assets from Shentel, which was accounted for as a business combination resulting in $1.0 billion in goodwill. The acquired goodwill was allocated to the wireless reporting unit and will be tested for impairment at this level. See Note 2 - Business Combinations for further information.

Intangible Assets

Identifiable Intangible Assets Acquired in the Sprint Merger

The following table summarizes the fair value of the intangible assets acquired in the Sprint Merger:


	Weighted Average Useful Life (in years)	Fair Value as of April 1, 2020 (in millions)
Spectrum licenses	Indefinite-lived	$	45,400
Tradenames (1)	2 years	207
Customer relationships	8 years	4,900
Favorable spectrum leases	18 years	745
Other intangible assets	7 years	428
Total intangible assets acquired		$	51,680

(1) Tradenames include the Sprint brand.

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. Therefore, we determined the spectrum licenses should be treated as indefinite-lived intangible assets. 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 team. Favorable spectrum leases of $745 million were recorded as an intangible asset as a result of purchase accounting and are 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 in our Condensed 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 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 preliminary 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.

Spectrum Licenses

The following table summarizes our spectrum license activity for the nine months ended September 30, 2021:


(in millions)	2021
Spectrum licenses, beginning of year	$	82,828

Spectrum license acquisitions	9,515
Spectrum licenses transferred to held for sale	(15)
Costs to clear spectrum	261

Spectrum licenses, end of period	$	92,589

Index for Notes to the Condensed Consolidated Financial Statements

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. At the inception of Auction 107 in October 2020, we deposited $438 million. Upon conclusion of Auction 107 in March 2021, we paid the FCC the remaining $8.9 billion for the licenses won in the auction. On July 23, 2021, the FCC issued to us the licenses won in Auction 107. The licenses are included in Spectrum licenses in our Condensed Consolidated Balance Sheets as of September 30, 2021. Cash payments to acquire spectrum licenses and payments for costs to clear spectrum are included in (Purchases) refunds of spectrum licenses and other intangible assets, including deposits in our Condensed Consolidated Statements of Cash Flows for the three and nine months ended September 30, 2021. We expect to incur an additional $1.0 billion in relocation costs which will be paid through 2024.

As of September 30, 2021, the activities that are necessary to get the C-band spectrum ready for its intended use have not begun, as such, capitalization of the interest associated with the costs of acquiring the C-band spectrum has not begun.

Other Intangible Assets

The components of Other intangible assets were as follows:

Other intangible assets		$	7,391	$	(2,344)	$	5,047	$	6,665	$	(1,367)	$	5,298

Amortization expense for intangible assets subject to amortization was $316 million and $383 million for the three months ended September 30, 2021 and 2020, respectively, and $977 million and $794 million for the nine months ended September 30, 2021 and 2020, respectively.

The estimated aggregate future amortization expense for intangible assets subject to amortization are summarized below:


(in millions)	Estimated Future Amortization

Twelve Months Ending September 30,
2022	$	1,128
2023	956
2024	799
2025	641
2026	480
Thereafter	1,043

Total	$	5,047

Substantially all of the estimated future amortization expense is associated with intangible assets acquired in the Merger and through our acquisitions of affiliates.

Note 6 – Fair Value Measurements

The carrying values of Cash and cash equivalents, Accounts receivable, Accounts receivable from affiliates, Accounts payable and accrued liabilities and borrowings under vendor financing arrangements with our primary network equipment suppliers approximate fair value due to the short-term maturities of these instruments.

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 (cash flow hedge) to help minimize significant, unplanned fluctuations in cash flows caused by interest rate volatility. We do not use derivatives for trading or speculative purposes.

Index for Notes to the Condensed Consolidated Financial Statements

Interest Rate Lock Derivatives

In October 2018, we entered into interest rate lock derivatives with notional amounts of $9.6 billion. In November 2019, we extended the mandatory termination date on our interest rate lock derivatives to June 3, 2020. For the three months ended March 31, 2020, we made net collateral transfers to certain of our derivative counterparties totaling $580 million, which included variation margin transfers to (or from) such derivative counterparties based on daily market movements. No amounts were transferred to the derivative counterparties subsequent to March 31, 2020. These collateral transfers are included in Net cash related to derivative contracts under collateral exchange arrangements within Net cash used in investing activities in our Condensed Consolidated Statements of Cash Flows.

We recorded interest rate lock derivatives on our Condensed Consolidated Balance Sheets at fair value that was derived primarily from observable market data, including yield curves. Interest rate lock derivatives were classified as Level 2 in the fair value hierarchy. Cash flows associated with qualifying hedge derivative instruments are presented in the same category on the Condensed Consolidated Statements of Cash Flows as the item being hedged.

Aggregate changes in the fair value of the interest rate lock derivatives, net of tax and amortization, of $1.5 billion and $1.6 billion are presented in Accumulated other comprehensive loss on our Condensed Consolidated Balance Sheets as of September 30, 2021 and December 31, 2020, respectively.

Between April 2 and April 6, 2020, in connection with the issuance of an aggregate of $19.0 billion of Senior Secured Notes bearing interest rates ranging from 3.500% to 4.500% and maturing in 2025 through 2050, we terminated our interest rate lock derivatives.

At the time of termination in the second quarter of 2020, 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 in our Condensed 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 nine months ended September 30, 2020.

Upon the issuance of debt to which the hedged interest rate risk related, we began amortizing the Accumulated other comprehensive loss related to the derivatives into Interest expense in a manner consistent with how the hedged interest payments affect earnings. For the three and nine months ended September 30, 2021, $47 million and $140 million, respectively, was amortized from Accumulated other comprehensive loss into Interest expense in the Condensed Consolidated Statements of Comprehensive Income. For the three and nine months ended September 30, 2020, $44 million and $83 million, respectively, was amortized from Accumulated other comprehensive loss into Interest expense. We expect to amortize $200 million of the Accumulated other comprehensive loss associated with the derivatives into Interest expense over the next 12 months.

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 in our Condensed Consolidated Balance Sheets, were $764 million and $884 million at September 30, 2021 and December 31, 2020, respectively. Fair value was equal to carrying amount at September 30, 2021 and December 31, 2020.

Debt

The fair value of our Senior Unsecured Notes and Senior Secured 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.

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

Index for Notes to the Condensed Consolidated Financial Statements

Notes to affiliates. The fair value estimates were based on information available as of September 30, 2021 and December 31, 2020. As such, our estimates are not necessarily indicative of the amount we could realize in a current market exchange.

The carrying amounts and fair values of our short-term and long-term debt included in our Condensed Consolidated Balance Sheets were as follows:


	Level within the Fair Value Hierarchy	September 30, 2021				December 31, 2020
(in millions)		Carrying Amount (1)		Fair Value (1)		Carrying Amount (1)		Fair Value (1)

Our effective interest rate, excluding the impact of derivatives and capitalized interest, was approximately 4.0% and 4.5% for the three months ended September 30, 2021 and 2020, respectively, and 4.1% and 4.7% for the nine months ended September 30, 2021 and 2020, respectively, on weighted average debt outstanding of $74.5 billion and $69.6 billion for the three months ended September 30, 2021 and 2020, respectively, and $74.4 billion and $54.5 billion for the nine months ended September 30, 2021 and 2020, respectively. The weighted average debt outstanding was calculated by applying an average of the monthly ending balances of total short-term and long-term debt and short-term and long-term debt to affiliates, net of unamortized premiums, discounts, debt issuance costs and consent fees.

On October 30, 2020, we entered into a $5.0 billion senior secured term loan commitment with certain financial institutions. On January 14, 2021, we issued an aggregate of $3.0 billion of Senior Notes. A portion of the senior secured term loan commitment was reduced by an amount equal to the aggregate gross proceeds of the Senior Notes, which reduced the commitment to $2.0 billion. On March 23, 2021, we issued an aggregate of $3.8 billion of Senior Notes. The senior secured term loan commitment was terminated upon the issuance of the $3.8 billion of Senior Notes.

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.

Note 8 – 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 at the end of the lease term. We lease back a portion of the space at certain tower sites for an initial term of 10 years, followed by optional renewals at customary terms.

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 in our condensed consolidated financial statements.

However, we also considered if this arrangement resulted in the sale of the CCI Lease Sites for which we would de-recognize 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 balance sheet. We recorded long-term financial obligations in the amount of the net proceeds received and recognize interest on the tower obligations at a rate of approximately 8% using the effective interest method. 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 operation of the tower sites.

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 for an initial term of 10 years, followed by optional renewals at customary terms.

We considered if this arrangement resulted in the sale of the Master Lease Sites for which we would de-recognize 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 balance sheet.

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 includes unfavorable terms associated with the fixed-price purchase option in 2037.

We recognize interest expense on the tower obligations at a rate of approximately 6% using the effective interest method. The tower obligations are increased by interest expense and amortized through contractual leaseback payments made by us to CCI.

Index for Notes to the Condensed Consolidated Financial Statements

The tower assets are reported in Property and equipment, net in our Condensed Consolidated Balance Sheets and are depreciated to their estimated residual values over the expected useful life of the towers, which is 20 years.

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


(in millions)	September 30, 2021		December 31, 2020
Property and equipment, net	$	2,591	$	2,838
Tower obligations	2,862		3,028
Other long-term liabilities	1,712		1,712

Future minimum payments related to the tower obligations are approximately $404 million for the year ending September 30, 2022, $638 million in total for the years ending September 30, 2023 and 2024, $605 million in total for the years ending September 30, 2025 and 2026, and $397 million in total for the years 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 $282 million in our Operating lease liabilities as of September 30, 2021.

Note 9 – 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, home internet, wearables, DIGITS (a service that allows our customers to use multiple mobile numbers on any compatible smartphone or device with internet connection), or other connected devices which includes tablets and SyncUP products;

•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:


	Three Months Ended September 30,				Nine Months Ended September 30,
(in millions)	2021		2020		2021		2020
Postpaid service revenues

Postpaid phone revenues	$	9,952	$	9,532	$	29,102	$	24,450
Postpaid other revenues	852		677		2,497		1,605

Total postpaid service revenues	$	10,804	$	10,209	$	31,599	$	26,055

We operate as a single operating segment. The balances presented within each revenue line item in our Condensed Consolidated Statements of Comprehensive Income represent categories of revenue from contracts with customers disaggregated by type of product and service. Service revenues also include revenues earned for providing premium services to customers, such as device insurance services and customer-based, third-party services. Revenue generated from the lease of mobile communication devices is included within Equipment revenues in our Condensed Consolidated Statements of Comprehensive Income.

We provide wireline communication services to domestic and international customers. Wireline service revenues were $179 million and $563 million for the three and nine months ended September 30, 2021, respectively, and were $213 million and $424 million for the three and nine months ended September 30, 2020, respectively. Wireline service revenues are presented in Other service revenues in our Condensed Consolidated Statements of Comprehensive Income.

Index for Notes to the Condensed Consolidated Financial Statements

Equipment revenues from the lease of mobile communication devices were as follows:


	Three Months Ended September 30,				Nine Months Ended September 30,
(in millions)	2021		2020		2021		2020
Equipment revenues from the lease of mobile communication devices	$	770	$	1,350	$	2,725	$	2,936

Contract Balances

The contract asset and contract liability balances from contracts with customers as of December 31, 2020 and September 30, 2021, were as follows:


(in millions)	Contract Assets		Contract Liabilities

Balance as of December 31, 2020	$	278	$	824
Balance as of September 30, 2021	262		792

Change	$	(16)	$	(32)

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.

The change in the contract asset balance includes customer activity related to new promotions, offset by billings on existing contracts and impairment which is recognized as bad debt expense. The current portion of our Contract assets of approximately $201 million and $204 million as of September 30, 2021 and December 31, 2020, respectively, was included in Other current assets in our Condensed 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 in our Condensed Consolidated Balance Sheets.

Revenues for the three and nine months ended September 30, 2021 and 2020 include the following:


	Three Months Ended September 30,				Nine Months Ended September 30,
(in millions)	2021		2020		2021		2020
Amounts included in the beginning of year contract liability balance	$	29	$	5	$	753	$	543

Remaining Performance Obligations

As of September 30, 2021, 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 $1.0 billion. We expect to recognize revenue as the service is provided on these postpaid contracts over an extended contract term of 24 months at the time of origination.

As of September 30, 2021, the aggregate amount of transaction price allocated to remaining service and lease performance obligations associated with operating leases was $286 million and $173 million, respectively. We expect to recognize this revenue as service is provided over the lease contract term of 18 months.

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. This variable consideration has been excluded from the disclosure of remaining performance obligations. As of September 30, 2021, the aggregate amount of the contractual minimum consideration for wholesale, roaming and service contracts is $386 million, $1.4 billion and $1.0 billion for 2021, 2022, and 2023 and beyond, respectively. These contracts have a remaining duration ranging from less than one year to nine years.

Contract Costs

The total balance of deferred incremental costs to obtain contracts was $1.3 billion and $1.1 billion as of September 30, 2021 and December 31, 2020, respectively, and is included in Other assets in our Condensed Consolidated Balance Sheets. Deferred contract costs incurred to obtain postpaid service contracts are amortized over a period of 24 months. The amortization period is

Index for Notes to the Condensed Consolidated Financial Statements

monitored to reflect any significant change in assumptions. Amortization of deferred contract costs is included in Selling, general and administrative expenses in our Condensed Consolidated Statements of Comprehensive Income and was $277 million and $221 million for the three months ended September 30, 2021 and 2020, respectively, and $789 million and $631 million for the nine months ended September 30, 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 three and nine months ended September 30, 2021 and 2020.

Note 10 – Income Taxes

Within our Condensed Consolidated Statements of Comprehensive Income, we recorded an Income tax benefit on continuing operations of $3 million and Income tax expense of $407 million for the three months ended September 30, 2021 and 2020, respectively, and Income tax expense of $520 million and $715 million for the nine months ended September 30, 2021 and 2020, respectively.

The change for the three months ended September 30, 2021 was primarily from tax benefits associated with legal entity reorganization related to historical Sprint entities, including a reduction in the valuation allowance against deferred tax assets in certain state jurisdictions and lower income before income taxes. The change for the nine months ended September 30, 2021 was primarily from tax benefits associated with legal entity reorganization related to historical Sprint entities, including a reduction in the valuation allowance against deferred tax assets in certain state jurisdictions, and a reduction in expenses that were not deductible for income tax purposes, partially offset by higher income before income taxes.

The effective tax rate from continuing operations was (0.3)% and 24.5% for the three months ended September 30, 2021 and 2020, respectively, and 16.7% and 26.4% for the nine months ended September 30, 2021 and 2020, respectively.

We continue to monitor positive and negative evidence related to the utilization of our deferred tax assets subject to a valuation allowance. It is possible the valuation allowance we deem to be necessary will be reduced within the next 12 months.

Note 11 – Earnings Per Share

The computation of basic and diluted earnings per share was as follows:

Index for Notes to the Condensed Consolidated Financial Statements

As of September 30, 2021, 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 September 30, 2021 and 2020. Potentially dilutive securities were not included in the computation of diluted earnings per share if to do so would have been anti-dilutive or if there was a loss from continuing operations for the period.

The SoftBank Specified Shares Amount of 48,751,557 shares of T-Mobile common stock was determined to be contingent consideration for the Merger and is not dilutive until the defined volume-weighted average price per share is reached.

Note 12 – 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 2041. 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 from five to 35 years. In addition, we have financing leases for network equipment that generally have a non-cancelable lease term of two to five years. The financing leases do not have renewal options and contain a bargain purchase option at the end of the lease.

On September 15, 2021, we modified the terms of one of our master lease agreements, which resulted in a $1.0 billion advance rent payment. Our operating lease liabilities were reduced as a result of this prepayment.

Maturities of lease liabilities as of September 30, 2021, were as follows:


(in millions)	Operating Leases		Finance Leases
Twelve Months Ending September 30,
2022	$	3,655	$	1,196
2023	4,282		846
2024	3,892		555
2025	3,401		150
2026	2,949		48
Thereafter	17,817		37
Total lease payments	35,996		2,832
Less: imputed interest	6,640		91
Total	$	29,356	$	2,741

Interest payments for financing leases were $15 million and $19 million for the three months ended September 30, 2021 and 2020, respectively, and $51 million and $59 million for the nine months ended September 30, 2021 and 2020, respectively.

As of September 30, 2021, we have additional operating leases for cell sites and commercial properties that have not yet commenced with future lease payments of approximately $227 million.

As of September 30, 2021, we were contingently liable for future ground lease payments related to certain tower obligations. These contingent obligations are not included in the above table as the amounts owed are contractually owed by Crown Castle International Corp. based on the subleasing arrangement. See Note 8 - Tower Obligations and Note 9 - Tower Obligations in Part II, Item 8 of our Annual Report on Form 10-K for the year ended December 31, 2020, for further information.

Note 13 – Commitments and Contingencies

Purchase Commitments

We have commitments for non-dedicated transportation lines with varying expiration terms that generally extend through 2030. 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 2045.

Index for Notes to the Condensed Consolidated Financial Statements

Our purchase commitments are approximately $4.5 billion for the twelve-month period ending September 30, 2022, $5.6 billion in total for the twelve-month periods ending September 30, 2023 and 2024, $2.2 billion in total for the twelve-month periods ending September 30, 2025 and 2026, and $1.7 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

In connection with the Merger, we assumed certain spectrum lease contracts from Sprint that include service obligations to the lessors. Certain of the 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.

Our spectrum lease and service credit commitments, including renewal periods, are approximately $360 million for the twelve-month period ending September 30, 2022, $617 million in total for the twelve-month periods ending September 30, 2023 and 2024, $591 million in total for the twelve-month periods ending September 30, 2025 and 2026 and $4.8 billion in total thereafter.

We accrue a monthly obligation for the services and equipment based on the total estimated available service credits divided by the term of the lease. The obligation is reduced by services provided and as actual invoices are presented and paid to the lessors. The maximum remaining service commitment on September 30, 2021 was $87 million and is expected to be incurred over the term of the related lease agreements, which generally range from 15 to 30 years.

Merger Commitments

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

We expect that our monetary commitments associated with these matters are approximately $9 million for the twelve-month period ending September 30, 2022, $13 million in total for the twelve-month periods ending September 30, 2023 and 2024 and $1 million in total for the twelve-month periods ending September 30, 2025 and 2026. These amounts do not represent our entire anticipated costs to achieve specified network coverage and performance requirements, employment targets or commitments to provide access to affordable rate plans, but represent only those amounts for which we are required to make a specified payment in connection with our commitments or settlements.

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 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 in the condensed consolidated 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

Index for Notes to the Condensed Consolidated Financial Statements

factual record. For Litigation and Regulatory Matters that may result in a contingent gain, we recognize such gains in the condensed consolidated financial statements when the gain is realized or realizable. 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 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 September 30, 2021, which was included in Accounts payable and accrued liabilities in our Condensed 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 to the Business Combination Agreement, SoftBank agreed to indemnify us against certain specified matters and losses, including those relating to Lifeline matters. 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. See Note 2 - Business Combinations for further information.

On June 1, 2021, a putative shareholder class action and derivative action 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. We intend to vigorously defend this lawsuit.

On October 2020, we notified MVNOs using the legacy Sprint CDMA network that we planned to sunset that network on December 31, 2021. In response to that notice, DISH, which has Boost Mobile customers who use the legacy Sprint CDMA network, has made several efforts to prevent us from sunsetting the CDMA network until mid-2023, including by urging the U.S. Department of Justice to move for a finding of contempt under the April 1, 2020 Final Judgment entered by the U.S. District Court for the District of Columbia, and by pursuing a Petition for Modification and related proceedings pursuant to the California Public Utilities Commission’s April 2020 decision concerning the T-Mobile-Sprint merger. We disagree with the merits of DISH’s positions and have opposed them. On October 22, 2021, we announced that we would delay the sunset of the legacy Sprint CDMA network for three months, until March 31, 2022, to, among other things, help ensure that DISH and other MVNOs fulfill their contractual responsibilities and transition customers off the legacy Sprint CDMA network before the sunset. We cannot predict the outcome of the proceedings described above, but we intend to vigorously oppose any efforts to further delay the sunset of the legacy Sprint CDMA network.

On August 12, 2021, we became aware of a potential 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 before 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 now complete and we believe we now have a full view of the data compromised.

Index for Notes to the Condensed Consolidated Financial Statements

As a result of the cyberattack, we have become subject to numerous lawsuits, including multiple class action lawsuits, that have been filed in numerous jurisdictions seeking unspecified monetary damages, costs and attorneys’ fees arising out of the cyberattack. A request to consolidate the federal class action lawsuits is pending before the Judicial Panel on Multidistrict Litigation and we anticipate a ruling on that request later this year or in early 2022. There can be no assurance that the request will be granted, and we are unable to predict at this time the potential timing and outcome of any of these claims (whether consolidated or not) and whether we may be subject to further private litigation. We intend to vigorously defend all of these lawsuits.

In addition, the Company has received inquiries from various government agencies, law enforcement and other governmental authorities related to the cyberattack. We are responding to these inquiries and cooperating fully with regulators. However, we cannot predict the timing or outcome of any of these inquiries, and whether we may be subject to further regulatory inquiries.

In light of the inherent uncertainties involved in such matters and based on the information currently available to us, as of the date of this Quarterly Report, we have not recorded any accruals for losses related to the above proceedings and inquiries, as any such amounts (or ranges of amounts) are not probable or estimable at this time. We believe it is reasonably possible that we could incur losses associated with these proceedings and inquiries, and the Company 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 proceedings and inquiries, 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.

Note 14 – 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 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 synergies in network costs.

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



(in millions)	Three Months Ended September 30, 2021		Nine Months Ended September 30, 2021		Incurred to Date
Contract termination costs	$	5	$	14	$	192
Severance costs	(3)		16		401
Network decommissioning	36		90		587
Total restructuring plan expenses	$	38	$	120	$	1,180

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

Our 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 $265 million and $649 million for the three and nine months ended September 30, 2021, respectively, and are included within Costs of services and Selling, general and administrative in our Condensed Consolidated Statements of Comprehensive Income. Restructuring expenses related to the acceleration or termination of leases were $80 million for both the three and nine months ended September 30, 2020.

The changes in the liabilities associated with our restructuring initiatives, including expenses incurred and cash payments, are as follows:


(in millions)	December 31, 2020		Expenses Incurred		Cash Payments		Adjustments for Non-Cash Items (1)		September 30, 2021
Contract termination costs	$	81	$	14	$	(73)	$	(1)	$	21
Severance costs	52		16		(63)		(3)		2
Network decommissioning	30		90		(88)		(16)		16
Total	$	163	$	120	$	(224)	$	(20)	$	39

(1) Non-cash items consists of non-cash stock-based compensation included within Severance costs and the write-off of assets within Network decommissioning.

The liabilities accrued in connection with our restructuring initiatives are presented in Accounts payable and accrued liabilities in our Condensed Consolidated Balance Sheets.

Our restructuring activities are expected to occur over the next three years with substantially all costs incurred by the end of fiscal year 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.

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 condensed 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 financial statements; and

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

Our MD&A is performed on a consolidated basis and is inclusive of the results and operations of Sprint prospectively from the close of the Merger on April 1, 2020. The Merger enhanced our spectrum portfolio, increased our customer base, altered our product mix and created opportunities for synergies in our operations. We anticipate an initial increase in our combined operating costs, which we expect to decrease as we realize synergies. We expect the trends and results of operations of the combined company to be materially different than those of the standalone entities.

Table of Contents

Our MD&A is provided as a supplement to, and should be read together with, our unaudited condensed consolidated financial statements for the three and nine months ended September 30, 2021, included in Part I, Item 1 of this Form 10-Q and audited consolidated financial statements included in Part II, Item 8 of our Annual Report on Form 10-K for the year ended December 31, 2020. 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

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. We expect the trends and results of operations of the combined company to be materially different than those of the standalone entities. 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 the Merger, see Note 2 – Business Combinations of the Notes to the Condensed Consolidated Financial Statements.

Shentel Wireless Assets Acquisition

On July 1, 2021, we completed the acquisition of Shentel’s wireless telecommunications assets (the “Wireless Assets”) used to provide Sprint PCS’s wireless mobility communications network products in certain parts of Maryland, North Carolina, Virginia, West Virginia, Kentucky, Ohio and Pennsylvania. As a result, T-Mobile become the legal owner of the Wireless Assets.

This transaction represented an opportunity to reacquire the exclusive rights to deliver Sprint’s wireless network services in Shentel’s former affiliate territory and simplify our operations. The acquisition of the Wireless Assets has altered the composition of certain assets and liabilities on our balance sheet, including Goodwill and Other intangible assets.

For more information regarding our acquisition of the Wireless Assets, see Note 2 – Business Combinations of the Notes to the Condensed 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 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.

Transaction and restructuring costs are disclosed in Note 2 – Business Combinations and Note 1 4 - Restructuring Costs, respectively, of the Notes to the Condensed 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. Cash payments for Merger-related costs, including payments related to our restructuring plan, are included in Net cash provided by operating activities in our Condensed Consolidated Statements of Cash Flows.

Merger-related costs during the three and nine months ended September 30, 2021 and 2020, are presented below:


(in millions)	Three Months Ended September 30,				Change				Nine Months Ended September 30,				Change

NM - Not Meaningful

Merger-related costs will be impacted by restructuring and integration activities expected to occur over the next three years, increasing throughout 2021 and 2022, as we implement initiatives to realize cost efficiencies from the Merger. Transaction costs, including legal and professional service fees related to the completion of the Merger and acquisitions of affiliates, are expected to continue to decrease in periods subsequent to the close of the Merger and acquisitions of affiliates.

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 synergies in network costs.

Anticipated Impacts

Our integration and restructuring activities are expected to occur over the next three years with substantially all costs incurred by the end of fiscal year 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.

As a result of our ongoing restructuring activities, we expect to realize cost efficiencies by eliminating redundancies within our combined network as well as other business processes and operations. We expect these activities to result in a reduction of expenses within Cost of services and Selling, general and administrative in our Condensed Consolidated Statements of Comprehensive Income.

For more information regarding our restructuring activities, see Note 1 4 – Restructuring Costs of the Notes to the Condensed Consolidated Financial Statements.

Cyberattack

As we previously reported in our Current Reports on Forms 8-K furnished with the Securities and Exchange Commission on August 16, 17, 20 and 27, 2021, we were subject to a criminal cyberattack involving unauthorized access to T-Mobile’s systems. We became aware of a potential issue on August 12, 2021. We immediately began a forensic investigation and engaged cybersecurity experts to assist with the assessment of the incident and to help determine what data was impacted. As we previously reported, we promptly located and closed the unauthorized access to our systems. Our investigation uncovered that the perpetrator 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.

Based on the initial investigation findings, we moved to quickly identify current, former and prospective customers whose information was impacted and notify them, consistent with state and federal requirements. Simultaneously, we undertook a

Table of Contents

number of other measures to demonstrate our continued support and commitment to data privacy and protection and continued to work with our cybersecurity experts to finish our forensic investigation, with the goal to ensure we had a complete understanding of the scope and impact of the unauthorized access. We also coordinated our efforts with law enforcement.

Our forensic investigation took time, but it is now complete, although our overall investigation into the incident is ongoing. At this time, we believe we have a full view of the data compromised. We have no evidence that individual financial account numbers, such as full credit or debit card numbers, were accessed or taken in relation to the cyberattack.

Throughout our forensic investigation of this cyberattack, our top priority has been to support those individuals impacted by the cyberattack. We sent notifications to our customers and customer accounts whose names, dates of birth, Social Security numbers (“SSNs”)/Tax Identifiers (“Tax IDs”) and driver’s license/identification numbers (“ID Numbers”) were taken, consistent with state and federal requirements, including to approximately 7.8 million current customer accounts and approximately 40.0 million former and prospective customers. We also notified an additional 1.9 million former and prospective customers who had their names, dates of birth and ID Numbers (but not valid SSNs/Tax IDs) taken.

Out of an abundance of caution during the earliest days of our investigation and to help alleviate consumer concerns and confusion, we rapidly sent notifications to approximately 5.3 million customer accounts who had their names, dates of birth and addresses taken. These accounts did not have SSNs/Tax IDs or ID Numbers taken. Later in our investigation, we identified approximately 790,000 additional former and prospective customers who had similar information — names, dates of birth and, in many cases, addresses, but not SSNs/Tax IDs or ID Numbers — taken and sent them notifications consistent with state and federal requirements. Our investigation also identified approximately 26.0 million additional individuals with the same types of information taken, but for whom individual notifications were not required under state and federal law in light of the types of information taken. By that point, since our original notifications, we had already launched a broad-reaching communications outreach program through which we kept our customers and the public informed and made information available and accessible on our website to provide support for any individuals who may have been impacted, including information on how they could take steps to protect themselves.

We also took actions to proactively reset the personal identification numbers (“PINs”) for approximately 870,000 current customer accounts whose names and PINs may have been taken. We previously reported that further data files including phone numbers, International Mobile Equipment Identity (“IMEI”) numbers and International Mobile Subscriber Identity (“IMSI”) numbers were taken; a significant portion of this data was related to inactive devices. For a number of additional current Metro customers, these files included names but no other personally identifiable information.

As described above, taking steps to further ensure we are supporting individuals impacted by the cyberattack has been a top priority. As previously reported, this support has included:

•Offering two years of free identity protection services with McAfee’s ID Theft Protection Service to any person who believes they may be affected;

•Recommending that all eligible customers sign up for free scam-blocking protection through Scam Shield;

•Supporting individuals impacted by the cyberattack with additional best practices and practical security steps such as resetting PINs and passwords; and

•Publishing a customer support webpage that includes information and access to these tools at https://www.t-mobile.com/brand/data-breach-20211.

As described above, we take data protection and the protection of our customers very seriously, and we have worked diligently to further enhance security across our platforms throughout this process. As part of those efforts, and as we have previously reported, we have entered into long-term partnerships with the industry-leading cybersecurity experts at Mandiant, and with consulting firm KPMG LLP, as part of our efforts to ensure that the Company has cybersecurity practices that are among the best in our industry. We have also created a Cyber Transformation Office reporting directly to our Chief Executive Officer that will be responsible for managing our efforts.

We have incurred certain cyberattack-related expenses which were not material and expect to continue to incur additional expenses in future periods, including costs to investigate and remediate the attack, send notifications to customers and provide additional customer support and enhance customer protection, only some of which may be covered and reimbursable by insurance. We also intend to commit substantial additional resources towards cybersecurity initiatives over the next several years.

It is not possible to precisely measure the amount of lost revenue directly attributable to the cyberattack. We are unable to predict the full impact of the cyberattack 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. Accordingly, we are not able to predict with any certainty any possible future impact to our revenues or expenses attributable to the cyberattack, which could have a material adverse effect on our future results.

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 13 – Commitments and Contingencies of the Notes to the Condensed Consolidated Financial Statements and Part II, Item 1. Legal Proceedings, and we could be subject to additional lawsuits and inquiries. We are cooperating fully with regulators in connection with the inquiries, though we cannot predict the timing or outcome of any of these inquiries. In light of the inherent uncertainties involved in such matters and based on the information currently available to us, as of the date of this Quarterly Report, we have not recorded any accruals for losses related to the above proceedings and inquiries as any such amounts (or ranges of amounts) are not probable or estimable at this time. We believe it is reasonably possible that we could incur losses associated with these proceedings and inquiries, and the Company 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. Losses associated with any adverse judgments, settlements, penalties or other resolutions of such proceedings and inquiries, including ongoing costs related thereto, could be material to our business, reputation, financial condition, cash flows and operating results in future periods.

COVID-19 Pandemic

The Pandemic has resulted in a widespread health crisis that has adversely affected businesses, economies, and financial markets worldwide, and has caused significant volatility in the U.S. and international debt and equity markets. The impact of the Pandemic has been wide-ranging, including, but not limited to, the temporary closures of many businesses and schools, “shelter in place” orders, travel restrictions, social distancing guidelines and other governmental, business and individual actions taken in response to the Pandemic. These restrictions have impacted, and will continue to impact, our business, including the demand for our products and services and the ways in which our customers purchase and use them. In addition, the Pandemic has resulted in economic uncertainty and a significant increase in unemployment in the United States, which could affect our customers’ purchasing decisions and ability to make timely payments. Beginning in the first quarter of 2020, the Pandemic has peaked, subsided and seen a resurgence, leading to phased re-openings, as well as continuing or renewed containment measures. The availability of vaccines, as well as our continued social distancing measures and incremental cleaning efforts, have facilitated the continued operation of our retail stores, after certain closures during 2020. We will continue to monitor the Pandemic and its impacts and may adjust our actions as needed to continue to provide our products and services to our communities and employees.

As a critical communications infrastructure provider as designated by the government, our focus has been on providing crucial connectivity to our customers and impacted communities while ensuring the safety and well-being of our employees.

The following discussion and analysis is for the three and nine months ended September 30, 2021, compared to the same period in 2020 unless otherwise stated.

Total revenues increased $352 million, or 2%, for the three months ended and increased $11.3 billion, or 23%, for the nine months ended September 30, 2021. The components of these changes are discussed below.

Postpaid revenues increased $595 million, or 6%, for the three months ended and increased $5.5 billion, or 21%, for the nine months ended September 30, 2021.

The increase for the three and nine months ended September 30, 2021, was primarily from:

Performance Measures

In managing our business and assessing financial performance, we supplement the information provided by our 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 liquidity requirements. Although companies in the wireless industry may not define each of these measures in precisely the same way,

Table of Contents

we believe that these measures facilitate comparisons with other companies in the wireless industry on key operating and financial measures.

The performance measures presented below include the impact of the Merger on a prospective basis from the close date of April 1, 2020, and the impact of the acquisition of the Wireless Assets from Shentel on a prospective basis from the close date of July 1, 2021. Historical results prior to the respective close dates have not been retroactively adjusted.

Customers

A customer is generally defined as a SIM number with a unique T-Mobile identifier which is associated with an account that generates revenue. Customers are qualified either for postpaid service utilizing phones, home internet, wearables, DIGITS or other connected devices, which include tablets and SyncUp products, where they generally pay after receiving service, or prepaid service, where they generally pay in advance of receiving service.

The following table sets forth the number of ending customers:

In the third quarter of 2021, we acquired 716,000 postpaid phone customers and 90,000 postpaid other customers through our acquisition of the Wireless Assets from Shentel.

Total customers increased 6,558,000, or 7%, primarily from:

•Higher postpaid phone customers, primarily due to the continued success of new customer segments and rate plans and continued growth in existing and new markets, along with targeted promotional activity and increased retail store traffic due to closures arising from the Pandemic in the prior period;

•Higher postpaid other customers, primarily due to growth in other connected devices, primarily related to public and educational sector customers and wearable products, and growth in home internet; and

•Higher prepaid customers, primarily due to the continued success of our prepaid business due to promotional activity and rate plan offers.

(1) 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 decreased 710,000, or 35%, for the three months ended and increased 109,000, or 3%, for the nine months ended September 30, 2021.

The decrease for the three months ended September 30, 2021, was primarily from:

Table of Contents

•Lower postpaid other net customer additions, primarily due to elevated gross additions in the prior period related to the public and educational sector resulting from the Pandemic, as well as higher churn in the current period related to post-Pandemic demand levels; and

•Lower postpaid phone net customer additions, primarily due to higher churn, mostly offset by higher gross additions driven by switching activity returning to more normalized levels relative to muted conditions from the Pandemic in the prior year and continued growth from T-Mobile for Business; partially offset by

•Higher prepaid net customer additions, primarily driven by higher gross additions, partially offset by higher churn and migrations to postpaid plans.

The increase for the nine months ended September 30, 2021, was primarily from:

•Higher postpaid phone net customer additions, primarily due to increased retail store traffic due to closures arising from the Pandemic in the prior period, partially offset by higher churn; and

•Lower postpaid other net customer additions, primarily due to elevated gross additions in the prior period related to the public and educational sector resulting from the Pandemic and higher disconnects from an increased customer base.

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 have their service restored within a certain period of time. We believe that churn provides management, investors and analysts with useful information to evaluate customer retention and loyalty.

The following table sets forth the churn:


	Three Months Ended September 30,				Change	Nine Months Ended September 30,				Change
	2021		2020			2021		2020
Postpaid phone churn	0.96	%	0.90	%	6 bps	0.93	%	0.85	%	8 bps
Prepaid churn	2.90	%	2.86	%	4 bps	2.76	%	3.07	%	-31 bps

Postpaid phone churn increased 6 basis points for the three months ended and increased 8 basis points for the nine months ended September 30, 2021.

The increase for the three months ended September 30, 2021, was primarily from:

•More normalized switching activity relative to the muted Pandemic-driven conditions a year ago; and

•Elevated Sprint churn during the accelerated integration process.

The increase for the nine months ended September 30, 2021, was primarily from:

•Higher churn from customers acquired in the Merger; and

•More normalized switching activity relative to the muted Pandemic-driven conditions a year ago.

Prepaid churn increased 4 basis points for the three months ended and decreased 31 basis points for the nine months ended September 30, 2021.

Total Postpaid Accounts

A postpaid account is generally defined as a billing account number that generates revenue. Postpaid accounts are generally comprised of customers that are qualified for postpaid service utilizing phones, home internet, wearables, DIGITS or other connected devices which include tablets and SyncUp products, where they generally pay after receiving service.

(1) Includes accounts acquired in connection with the Merger and certain account base adjustments. See Account Base Adjustments table below.

(2) In the third quarter of 2021, we acquired 270,000 postpaid accounts through our acquisition of the Wireless Assets of Shentel.

Total postpaid customer accounts increased 1,278,000, or 5%, primarily due to the continued success of new customer segments and rate plans, continued growth in existing and new markets, including our home internet product, along with promotional activity and increased retail store traffic due to closures arising from the Pandemic in the prior period.

Account Base Adjustments

Certain adjustments were made to align the account reporting policies of T-Mobile and Sprint.

The adjustments made to the reported T-Mobile and Sprint ending account base as of March 31, 2020 are presented below:

(1) In connection with the closing of the Merger, we refined our definition of wholesale accounts resulting in the reclassification of certain postpaid and prepaid reseller accounts to wholesale accounts.

(2) Prepaid accounts with a customer with a device installment billing plan historically included as Sprint postpaid accounts have been reclassified to prepaid accounts to align with T-Mobile policy.

(3) Accounts with customers who have rate plans with monthly recurring charges which are considered insignificant have been excluded from our reported accounts.

(4) Certain Sprint accounts subject to collection activity for an extended period of time have been excluded from our reported accounts to align with T-Mobile policy.

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

Average Revenue Per User

ARPU represents the average monthly service revenue earned from customers. 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 home internet, wearables, DIGITS and other connected devices such as tablets and SyncUp products.

The following table illustrates the calculation of our operating measure ARPU and reconciles this measure to the related service revenues:

Postpaid Phone ARPU

Postpaid phone ARPU decreased $0.49, or 1%, for the three months ended and was essentially flat for the nine months ended September 30, 2021.

The decrease for the three months ended September 30, 2021, was primarily from:

•Promotional activity; and

•The impact of the transition of Sprint customers to tax-inclusive rate plans; partially offset by

•Higher premium services, including Magenta Max.

•The net impact of customers acquired in the Merger, which have higher ARPU (net of changes arising from the reduction in base due to policy adjustments and reclassification of certain ARPU components from the acquired customers being moved to other revenue lines).

Prepaid ARPU

Prepaid ARPU increased $1.00, or 3%, for the three months ended and increased $0.48, or 1%, for the nine months ended September 30, 2021, primarily due to:

•Higher premium services; and

•Higher revenues due to improved rate plan mix; partially offset by

•A reduction in certain non-recurring charges.

Average Revenue Per Account

Average Revenue per Account (“ARPA”) represents the average monthly postpaid service revenue earned per account. 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 home internet, wearables, DIGITS or other connected devices, which include tablets and SyncUp products.

The following table illustrates the calculation of our operating measure ARPA and reconciles this measure to the related service revenues:

Adjusted EBITDA and Core Adjusted EBITDA

Beginning in the first quarter of 2021, we began disclosing Core Adjusted EBITDA as a financial measure to improve comparability as we de-emphasize device leasing programs as part of our value proposition.

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 use 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

Table of Contents

measures to evaluate overall operating performance and facilitate comparisons with other wireless communications services companies because they are indicative of our ongoing 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 and incremental costs directly attributable to the Pandemic, as they are not indicative of our ongoing operating performance, as well as certain other nonrecurring income and expenses. 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 U.S. Generally Accepted Accounting Principles (“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 in the condensed consolidated financial statements. Additionally, certain stock-based compensation expenses associated with the Transactions have been included in Merger-related costs.

(3)Other, net may not agree with the Condensed Consolidated Statements of Comprehensive Income primarily due to certain non-routine operating activities, such as other special items that would not be expected to reoccur or are not reflective of T-Mobile’s ongoing operating performance, and are, therefore, excluded from Adjusted EBITDA and Core Adjusted EBITDA.

Table of Contents

Core Adjusted EBITDA increased $262 million, or 5%, for the three months ended and increased $3.0 billion, or 20%, for the nine months ended September 30, 2021. The components comprising Core Adjusted EBITDA are discussed further above.

The increase for the three months ended September 30, 2021 was primarily due to:

•Higher Total service revenues; and

•Higher Equipment revenues, excluding Lease revenues; partially offset by

•Higher Cost of equipment sales, excluding Merger-related costs.

The increase for the nine months ended September 30, 2021, was primarily due to:

•Higher Total service revenues; and

•Higher Equipment revenues, excluding Lease revenues; partially offset by

•Higher Cost of equipment sales, excluding Merger-related costs;

•Higher Cost of services, excluding Merger-related costs; and

•Higher Selling, general and administrative expenses, excluding Merger-related costs and supplemental employee payroll, third-party commissions and cleaning-related COVID-19 costs.

Adjusted EBITDA decreased $318 million, or 4%, for the three months ended and increased $2.8 billion, or 16%, for the nine months ended September 30, 2021. The changes were primarily due to the fluctuations in Core Adjusted EBITDA, discussed above, including changes in Lease revenues. Lease revenues decreased $580 million for the three months ended and $211 million for the nine months ended September 30, 2021.

Liquidity and Capital Resources

Our principal sources of liquidity are our cash and cash equivalents and cash generated from operations, proceeds from issuance of long-term debt and common stock, financing leases, the sale of certain receivables, financing arrangements of vendor payables which effectively extend payment terms and the Revolving Credit Facility (as defined below). Further, the incurrence of additional indebtedness may inhibit our ability to incur new debt under the terms governing our existing and future indebtedness, which may make it more difficult for us to incur new debt in the future to finance our business strategy.

Cash Flows

The following is a condensed schedule of our cash flows for the three and nine months ended September 30, 2021 and 2020:

Net cash provided by operating activities increased $705 million, or 25%, for the three months ended and increased $5.8 billion, or 111%, for the nine months ended September 30, 2021.

The increase for the three months ended September 30, 2021, was primarily from:

•A $1.8 billion decrease in net cash outflows from changes in working capital, primarily due to lower use of cash from Accounts receivable, Accounts payable and accrued liabilities and Inventories, partially offset by higher use of cash from operating lease liabilities, including a $1.0 billion advance rent payment related to the modification of one of our master lease agreements; partially offset by

•A $1.1 billion decrease in Net income, adjusted for non-cash income and expense.

•Net cash provided by operating activities includes $617 million and $379 million in payments for Merger-related costs for the three months ended September 30, 2021 and 2020, respectively.

The increase for the nine months ended September 30, 2021, was primarily from:

•A $4.2 billion decrease in net cash outflows from changes in working capital, primarily due to the one-time impact of $2.3 billion in gross payments for the settlement of interest rate swaps related to Merger financing for the nine months ended September 30, 2020, included in the use of cash from Other current and long-term liabilities, as well as lower use of cash from Inventories, Accounts payable and accrued liabilities and operating lease right-of-use assets, partially offset by higher use of cash from Equipment installment plan receivables and operating lease liabilities, including a $1.0 billion advance rent payment related to the modification of one of our master lease agreements; and

•A $1.5 billion increase in Net income, adjusted for non-cash income and expense.

•Net cash provided by operating activities includes $1.1 billion and $910 million in payments for Merger-related costs for the nine months ended September 30, 2021 and 2020, respectively.

Investing Activities

Net cash used in investing activities increased $3.0 billion, or 267%, for the three months ended and increased $8.4 billion, or 93%, for the nine months ended September 30, 2021.

Cash and Cash Equivalents

As of September 30, 2021, our Cash and cash equivalents were $4.1 billion compared to $10.4 billion at December 31, 2020.

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, less Cash payments for debt prepayment or debt extinguishment. Free Cash Flow and Free Cash Flow, excluding gross payments for the settlement of interest rate swaps, are non-GAAP financial measures utilized by our management, investors and analysts of our financial information to evaluate cash available to pay debt and provide further investment in the business.

In the second quarter of 2021, we sold tower sites for proceeds of $31 million, which are included in Proceeds from sales of tower sites within Net cash used in investing activities in our Condensed 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.

Borrowing Capacity

We maintain a financing arrangement with Deutsche Bank AG, which allows for up to $108 million in borrowings. Under the financing arrangement, we can effectively extend payment terms for invoices payable to certain vendors. As of September 30, 2021, there were no outstanding balances under such financing arrangement.

We also maintain vendor financing arrangements primarily with our main network equipment suppliers. Under the respective agreements, we can obtain extended financing terms. During the three and nine months ended September 30, 2021, we repaid $76 million and $167 million, respectively, associated with the vendor financing arrangements and other financial liabilities. These payments are included in Repayments of short-term debt for purchases of inventory, property and equipment and other financial liabilities, in our Condensed Consolidated Statements of Cash Flows. As of September 30, 2021 and December 31, 2020, the outstanding balance under the vendor financing arrangements and other financial liabilities was $69 million and $240 million, respectively, of which $12 million and $122 million, respectively, was assumed in connection with the closing of the Merger.

We maintain a revolving credit facility (the “Revolving Credit Facility”) with an aggregate commitment amount of $5.5 billion. As of September 30, 2021, there was no outstanding balance under the Revolving Credit Facility.

On October 30, 2020, we entered into a $5.0 billion senior secured term loan commitment with certain financial institutions. On January 14, 2021, we issued an aggregate of $3.0 billion of senior notes. The senior secured term loan commitment was reduced by an amount equal to the aggregate gross proceeds of the Senior Notes, which reduced the commitment to $2.0 billion. On March 23, 2021, we issued an aggregate of $3.8 billion of Senior Notes. The senior secured term loan commitment was terminated upon the issuance of the $3.8 billion of Senior Notes.

As of September 30, 2021, our total debt and financing lease liabilities were $75.2 billion, excluding our tower obligations, of which $68.1 billion was classified as long-term debt and $1.6 billion was classified as long-term financing lease liabilities.

During the nine months ended September 30, 2021, we issued long-term debt for net proceeds of $11.8 billion and redeemed and repaid short- and long-term debt with an aggregate principal amount of $10.1 billion.

Spectrum Auction

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. At the inception of Auction 107 in October 2020, we deposited $438 million. Upon conclusion of Auction 107 in March 2021, we paid the FCC the remaining $8.9 billion for the licenses won in the auction. We expect to incur an additional $1.2 billion in relocation costs which will be paid through 2024.

For more information regarding our spectrum licenses, see Note 5 - Goodwill, Spectrum License Transactions and Other Intangible Assets of the Notes to the Condensed 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 September 30, 2021, we derecognized net receivables of $2.5 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 Condensed Consolidated Financial Statements.

Future Sources and Uses of Liquidity

We may seek additional sources of liquidity, including through the issuance of additional long-term debt in 2021, to continue to opportunistically acquire spectrum licenses or other assets in private party transactions or for the refinancing of existing long-term debt on an opportunistic basis. Excluding liquidity that could be needed for spectrum acquisitions, or for other assets, 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 high yield callable debt, tower obligations, potential stockholder returns and the execution of our integration plan.

We determine future liquidity requirements, for both operations and capital expenditures, based in large part upon projected financial and operating performance, and opportunities to acquire additional spectrum. 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. 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, pay dividends and make distributions on our common stock, make certain investments, repurchase stock, create liens or other encumbrances, enter into transactions with affiliates, enter into transactions that restrict dividends or distributions from subsidiaries, and merge, consolidate or sell, or otherwise dispose of, substantially all of their assets. Certain provisions of each of the credit agreements, indentures and supplemental indentures relating to the long-term debt to affiliates and third parties restrict the ability of the Issuers or borrowers to loan funds or make payments to Parent. However, the Issuers or borrowers are allowed to make certain permitted payments to Parent under the terms of each of the credit agreements, indentures and supplemental indentures relating to the long-term debt to affiliates and third parties. We were in compliance with all restrictive debt covenants as of September 30, 2021.

Shentel Wireless Assets Acquisition

On July 1, 2021, we closed on the acquisition of the Wireless Assets (as defined in Note 2 – Business Combinations of the Notes to the Condensed Consolidated Financial Statements) for a cash purchase price of approximately $1.9 billion. For more information regarding the acquisition of the Wireless Assets, see Note 2 – Business Combinations of the Notes to the Condensed Consolidated Financial Statements.

Financing Lease Facilities

We have entered into uncommitted financing lease facilities with certain partners that provide us with the ability to enter into financing leases for network equipment and services. As of September 30, 2021, we have committed to $6.2 billion of financing leases under these financing lease facilities, of which $599 million and $1.1 billion was executed during the three and nine months ended September 30, 2021, respectively. We expect to enter into up to an additional $131 million in financing lease commitments during the year ending December 31, 2021.

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, customer base and business practices of T-Mobile and Sprint. Property and equipment capital expenditures primarily relate to the integration of our network and spectrum licenses, including the acquired C-band licenses won in Auction 107, acquired Sprint 2.5 GHz spectrum licenses and existing 600 MHz spectrum licenses as we build out our nationwide 5G network. We expect the majority of our remaining capital expenditures related to these efforts to occur in 2021 and 2022, after which we expect a reduction in capital expenditure requirements.

For more information regarding our spectrum licenses, see Note 5 - Goodwill, Spectrum License Transactions and Other Intangible Assets of the Notes to the Condensed Consolidated Financial Statements.

Dividends

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.

Related Party Transactions

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

Disclosure of Iranian Activities under Section 13(r) of the Securities Exchange Act of 1934

Section 219 of the Iran Threat Reduction and Syria Human Rights Act of 2012 added Section 13(r) to the Exchange Act of 1934, as amended (“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 three months ended September 30, 2021, that requires disclosure in this report under Section 13(r) of the Exchange Act, except as set forth below with respect to affiliates that we do not control and that are our affiliates solely due to their common control with either DT or SoftBank. We have relied upon DT and SoftBank for information regarding their respective activities, transactions and dealings.

DT, through certain of its non-U.S. subsidiaries, is party to roaming and interconnect agreements with the following mobile and fixed line telecommunication providers in Iran, some of which are or may be government-controlled entities: Irancell Telecommunications Services Company, Telecommunication Kish Company, Mobile Telecommunication Company of Iran, and Telecommunication Infrastructure Company of Iran. In addition, during the three months ended September 30, 2021, DT, through certain of its non-U.S. subsidiaries, provided basic telecommunications services to two customers in Germany identified on the Specially Designated Nationals and Blocked Persons List maintained by the U.S. Department of Treasury’s

Table of Contents

Office of Foreign Assets Control: Bank Melli and Europäisch-Iranische Handelsbank. These services have been terminated or are in the process of being terminated. For the three months ended September 30, 2021, 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 three months ended September 30, 2021 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 three months ended September 30, 2021, 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 three months ended September 30, 2021, 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 three months ended September 30, 2021, were both under $0.1 million. We understand that the SoftBank subsidiary intends to continue such activities.

Critical Accounting Policies and Estimates

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures designed to ensure information required to be disclosed in our periodic 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 include the use of a Disclosure Committee which is comprised of representatives from our Accounting, Legal, Treasury, Technology, Risk Management, Government Affairs and Investor Relations functions and are 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, as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act. 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-Q.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

For more information regarding the legal proceedings in which we are involved, see Note 2 - Business Combinations and Note 1 3 – Commitments and Contingencies of the Notes to the Condensed Consolidated Financial Statements.

Item 1A. Risk Factors

Other than the updated risk factors below, there have been no material changes in our risk factors as previously disclosed in Part I, Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2020.

Our Fifth Amended and Restated 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 Fifth Amended and Restated Certificate of Incorporation (the “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.

Our business and Sprint’s business may not be integrated successfully or such integration may be more difficult, time consuming or costly than expected. Operating costs, customer loss and business disruptions, including challenges in maintaining relationships with employees, customers, suppliers or vendors, may be greater than expected.

The combination of two independent businesses is complex, costly and time-consuming, and may divert significant management attention and resources. This process may disrupt our business or otherwise impact our ability to compete. The overall combination of our and Sprint’s businesses may also result in material unanticipated problems, expenses, liabilities, competitive responses and impacts, and loss of customers and other business relationships. The difficulties of combining the operations of the companies include, among others:

•diversion of management attention to integration matters;

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

•challenges in conforming standards, controls, procedures and accounting and other policies;

•alignment of key performance measurements may result in a greater need to communicate and manage clear expectations while we work to integrate and align policies and practices;

•difficulties in integrating employees;

•the transition of management to the combined company management team, and the need to address possible differences in corporate cultures, management philosophies, and compensation structures;

•challenges in retaining existing customers and obtaining new customers;

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

•any disruptions to the operations and business in the Shentel service area following the Company’s acquisition of Wireless Assets (as defined in Note 2 – Business Combinations of the Notes to the Condensed Consolidated Financial Statements) as a result of the transition of such assets to the Company;

Table of Contents

•compliance with Government Commitments relating to national security;

•known or potential unknown liabilities of Sprint that are larger than expected; and

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

Additionally, uncertainties over the integration process could cause customers, suppliers, distributors, dealers, retailers and others to seek to change or cancel our existing business relationships or to refuse to renew existing relationships. Suppliers, distributors and content and application providers may also delay or cease developing new products for us that are necessary for the operations of our business due to uncertainties. Competitors may also target our existing customers by highlighting potential uncertainties and integration difficulties.

Some of these factors are outside our control, and any one of them could result in lower revenues, higher costs and diversion of management time and energy, which could adversely impact our business, financial condition and operating results. In addition, even if the integration is successful, the full benefits of the Transactions including, among others, the synergies, cost savings or sales or growth opportunities may not be realized within the anticipated time frames or at all.

We have recently experienced a criminal cyberattack and could in the future be further harmed by disruption, data loss or other security breaches, whether directly or indirectly.

Our business involves the receipt, storage and transmission of our customers’ confidential information, including sensitive personal information and payment card information, confidential information about our employees and suppliers, and other sensitive information about our Company, such as our business plans, transactions and intellectual property (collectively, “Confidential Information”). Unauthorized access to Confidential Information is difficult to anticipate, detect or prevent, particularly given that the methods of unauthorized access constantly change and evolve. We and our third-party service providers are subject to attacks and threats to our and their IT networks, systems and supply chain, including attacks and threats by state-sponsored parties, malicious actors, employees or third parties, who may exploit bugs, errors, misconfigurations or other vulnerabilities that can compromise the confidentiality and integrity of Confidential Information or cause serious operational disruptions (e.g., ransomware).

As a telecommunications carrier, we are considered a critical infrastructure provider and therefore are likely to be the target of cyberattacks (e.g., denial of service and other malicious attacks). In addition, the Pandemic has presented additional operational and cybersecurity risks to our IT systems due to work-from-home arrangements at the Company and our providers. Attacks against companies like ours are perpetrated by a variety of groups or persons, including those 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 provide confidential, proprietary and personal information to third-party service providers as part of our business operations. These third-party service providers have experienced data breaches and other attacks that included unauthorized access to Confidential Information and operational disruptions in the past, and face 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 the 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 and expect to continue to incur additional expenses in future periods, including costs to investigate and remediate the attack, send notifications to customers and provide additional customer support and enhance customer protection. For more information, see “Cyberattack” in the Overview section of MD&A. As a result of this cyberattack, we are subject to numerous 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 13 – Commitments and Contingencies of the Notes to the Consolidated Financial Statements, and “– Unfavorable outcomes of legal proceedings may adversely affect our business, reputation, financial condition, cash flows and operating results” below. As a result of this cyberattack or other cyberattacks or security breaches involving our Company or our third-party suppliers, 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 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 August 2021 cyberattack, we have previously experienced other incidents involving unauthorized access to certain Confidential Information, and we expect to experience cyberattacks and other cybersecurity incidents in the future.

Table of Contents

Typically, these incidents have involved attempts to commit fraud by taking control of a customer’s phone line. In other cases, the incidents have also involved unauthorized access to certain of our customers’ private information, including credit card information, financial data, social security numbers or passwords.

Our procedures and safeguards to prevent unauthorized access to sensitive data and to defend against attacks seeking to disrupt our services must be continually evaluated and revised to address the ever-evolving threat landscape and changing cybersecurity regulations, which could require the investment of significant resources. We cannot make assurances that all preventive actions taken will adequately repel a significant attack or prevent security breaches or misuses of data, unauthorized access by third parties or employees or exploits against third-party supplier environments, or that we or our third-party suppliers will be able to effectively identify, investigate or remediate such incidents. We expect to continue to be the target of cyberattacks, data breaches or security incidents, given the nature of our business. Any future cyberattacks, data breaches, or security incidents may have a material adverse effect on our business, reputation, financial condition, cash flows and operating results.

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 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, it is possible that stockholders of T-Mobile and/or Sprint may file 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 actions and other proceedings, including, 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 customers even though those customers 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 customer 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. 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 was included in Accounts payable and accrued liabilities in our Consolidated Balance Sheets.

As a result of the August 2021 cyberattack, we are subject to numerous lawsuits, including multiple class action lawsuits seeking unspecified monetary damages, 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 action and other lawsuits. In light of the inherent uncertainties involved in these proceedings and inquiries, as of the date of this Quarterly Report, we have not recorded any accruals for losses related to these proceedings and inquiries, as any such amounts are not yet probable or estimable. We believe it is reasonably possible that we could incur 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 proceedings and inquiries, 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

Table of Contents

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.

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. 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 law are issued or applied. In many cases, the application of existing, newly enacted or amended tax laws (such as the Coronavirus Aid, Relief, and Economic Security Act of 2020 or the U.S. Tax Cuts and Jobs Act of 2017) 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 recent 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.

In the event that T-Mobile, including pre-acquisition Sprint, has incorrectly described, disclosed, determined, calculated, assessed, or remitted amounts that were due to governmental authorities, we could be subject to additional taxes, fines, penalties, or other adverse actions, which could materially impact our business, financial condition and operating results. 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, such as a proposed corporate minimum tax or new limits on interest deductibility, it could have a material adverse effect on our business, financial condition and operating results.
