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, 2020.2021.

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”). These estimatescircumstances. Estimates are inherently subject to judgment and actual results could differ from those estimates.

Accounting Pronouncements Not Yet Adopted During the Current Year

Reference Rate Reform

In March 2020, the Financial Accounting Standards Board (“FASB”) issued ASUAccounting Standards Update (“ASU”) 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting.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.

Note 2 – Business Combination

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

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 Group Corp. (“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.Accounting Pronouncements Not Yet Adopted

On February 20, 2020, T-Mobile, SoftBankTroubled Debt Restructurings and Deutsche Telekom AG (“DT”) entered into a letter agreement (the “Letter Agreement”). Pursuant toVintage Disclosures

In March 2022, the Letter Agreement, SoftBank agreed to cause its applicable affiliates to surrender to T-Mobile,FASB issued ASU 2022-02, “Financial Instruments—Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures.” The standard eliminates the accounting guidance within ASC 310-40 for 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 stocktroubled debt restructurings by creditors while enhancing disclosure requirements 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 9.75certain loan refinancings and restructurings by

Early adoption is permitted 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,us 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 NaN 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 expect to be 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.

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

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 Sprint common stock issued and outstanding as of March 31, 2020, an 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 whichtime. We 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 expenses associated with the Merger.

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,
9

Index for Notes to the Condensed Consolidated Financial Statements
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 estimated future share-price volatility, which was based on historical market trends and 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 previously disclosed for the estimated values of certain acquired assets and liabilities assumed have been adjusted based on additional information arising subsequent to the initial valuation. The measurement period adjustments we recognized during the three months ended March 31, 2021 did not have a significant impact on our Condensed Consolidated Statements of Comprehensive Income for the three months ended March 31, 2021.

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. NaN 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.

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 FCC to resolve certain Lifeline matters, which resulted in a payment of $200 million by SoftBank. Final resolution of this matter 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. 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 $13 million and $38 million for the three months ended March 31, 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.

Shenandoah Personal Communications Company Affiliate Relationship

Sprint PCS (specifically Sprint Spectrum L.P.) is party to a variety of publicly filed agreements with Shenandoah Personal Communications Company LLC (“Shentel”), pursuant to which Shentel is 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 used to provide services pursuant to the Management Agreement. On August 26, 2020, Sprint, now our direct 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. The exercise of this option triggered a requirement for the parties to engage three independent valuation providers to calculate the “entire business value” (the “Entire Business Value”) of such wireless telecommunications assets, pursuant to a formula and valuation process prescribed in the Management Agreement.

On February 1, 2021, in accordance with the Management Agreement and other agreed-upon terms, the Entire Business Value of Shentel’s wireless telecommunication assets used to provide services pursuant to the Management Agreement was determined to be $2.1 billion, and correspondingly, the base purchase price for such wireless telecommunication assets shall be ninety percent (90%) of that Entire Business Value amount ($1.9 billion), subject to certain other purchase price adjustments prescribed by the Management Agreement and such additional purchase price adjustments agreed by the parties. The parties are negotiating the remaining outstanding terms of a definitive agreement to govern the purchase of Shentel’s wireless telecommunication assets and expect the transaction to close in the third quarter of 2021 after satisfying customary conditions to closing.financial statements.

Note 32 – Receivables and ExpectedRelated Allowance for Credit Losses

We maintain an allowance for credit losses by applying an expected credit losses that assesses the lifetime credit losses that we expect to incur related to our receivable portfolio segments.loss model. Each period, management assesses the appropriateness of the level of allowance for credit losses by considering credit risk inherent within each portfolio segment as of period end.

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

Our portfolio of receivables is comprised of 2 portfolio segments: accounts receivable and EIPequipment installment plan (“EIP”) receivables.

Accounts Receivable Portfolio Segment

Our accountsAccounts receivable segment primarily consistsbalances are predominately composed of amounts currently due from customers including service(e.g., for wireless services and leasedmonthly device receivables,lease payments), device insurance administrators, wholesale partners, non-consolidated affiliates, other carriers and third-party retail channels and other carriers.channels.

We estimate expected credit losses associated with our accounts receivable portfolio segment using an expected credit loss model, which utilizes an aging schedule methodology that utilizesbased on historical information and adjusted for asset-specific considerations, current economic conditions to develop expected credit losses by aging bucket, including for receivables that are not past due.and reasonable and supportable forecasts.

To determine the appropriate credit loss percentages by aging bucket, we considerOur approach considers 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, andseverity. We also consider other qualitative factors such as macro-economic conditions, including the expected economic impacts of the COVID-19 pandemic (the “Pandemic”).conditions.

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 professionalexternal 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.purchases if their assessed credit risk exceeds established underwriting thresholds. In addition, certain customers within the Subprime category aremay be required to pay a deposit.

To determine a customer’s credit profile and assist in determining their credit class, we use a proprietary credit scoring model that measures the credit quality of a customer 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 scorereceivables had a combined weighted-average effective interest rate of 5.7% and credit profile, these acquired customers were classified into our customer classes5.6% as of Prime or Subprime. Our proprietary credit scoring model is applied to all EIP arrangements originated after the Merger close date.March 31, 2022 and December 31, 2021, respectively.

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

We estimate expected credit losses on our EIP receivables segment by usingapplying an expected credit loss model, which relies on historical loss data adjusted for current conditions to calculate default probabilities or an estimate for our outstanding EIP loans. We consider various risk characteristics when calculatingthe frequency of customer default. Our assessment of default probabilities such asincludes receivables delinquency status, historical loss experience, how long such loansthe receivables have been outstanding and customer credit ratings, as well as customer tenure, delinquency status and other correlated variables identified through statistical analyses.tenure. We multiply these estimated default probabilities by our estimated loss given default, which considersis the estimated amount or severity of the default loss after adjusting for estimated recoveries.

As we do for our accounts receivable portfolio segment, we consider the need to adjust our estimate of expectedcredit 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.analyses.

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 6.7% as of both March 31, 2021 and December 31, 2020.

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.

On April 30, 2020, we agreed with the purchaser banks to update our collection policies to temporarily allow for flexibility for modifications to the EIP receivables sold that are impacted by the Pandemic and exclusion of such EIP receivables from all pool performance triggers.

As of both March 31, 20212022 and December 31, 2020,2021, the EIP sale arrangement provided funding of $1.3 billion. Sales of EIP receivables occur daily and are settled on a monthly basis.

In connection with this EIP sale arrangement, we formed a wholly owned subsidiary, which qualifies as a bankruptcy remote entity (the “EIP BRE”). Pursuant toWe consolidate the EIP sale arrangement, our wholly owned subsidiary transfers selected receivables toBRE under 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.VIE model.

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.

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.February 2023. As of both March 31, 20212022 and December 31, 2020,2021, 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.million.

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 amendedWe consolidate 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 consolidateService BRE under the original structure and changes in 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.VIE model.

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.

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 inon 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 March 31, 20212022 and December 31, 2020,2021, our deferred purchase price related to the sales of service receivables and EIP receivables was $769$719 million and $884$779 million, respectively.

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.

On April 1, 2020, we completed our Merger with Sprint, 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 Combination for further information.

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.

Index for Notes to the Condensed Consolidated Financial Statements
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.

Note 65 – Fair Value Measurements

The carrying values of Cash and cash equivalents, Accounts receivable Accounts receivable from affiliates,and 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.

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

Interest Rate Lock Derivatives
In April 2020, we terminated our interest rate lock derivatives entered into in October 2018.

Aggregate changes in the fair value of the interest rate lock derivatives, net of tax and amortization, of $1.6$1.4 billion and $1.5 billion are presented in Accumulated other comprehensive loss on our Condensed Consolidated Balance Sheets as of both March 31, 20212022 and December 31, 2020.
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.2021, respectively.

Upon the issuance of debt to which the hedged interest rate risk related, we began amortizing the Accumulated other comprehensive loss with the derivatives into Interest expense in a manner consistent with how the hedged interest payments affect earnings. For the three months ended March 31, 2022 and 2021, $50 million and $46 million, wasrespectively, were amortized from Accumulated other comprehensive loss into Interest expense, net in the Condensed Consolidated Statements of Comprehensive Income. NaN amounts were amortized into Interest expense for the three months ended March 31, 2020. We expect to amortize $192$207 million of the Accumulated other comprehensive loss associated with the derivatives into Interest expense, net over the next 12 months.months ended March 31, 2023.

Deferred Purchase Price Assets
In connection with the sales of certain service and EIP accounts receivable pursuant to the sale arrangements, we have deferred purchase price assets measured at fair value that are based on a discounted cash flow model using unobservable Level 3 inputs, including customer default rates. See Note 43 – 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 inon our Condensed Consolidated Balance Sheets, were $769$719 million and $884$779 million atas of March 31, 20212022 and December 31, 2020,2021, respectively. Fair value was equal to the carrying amount at March 31, 20212022 and December 31, 2020.2021.

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 Notes to affiliates. The fair value estimates were based on information available as of March 31, 20212022 and December 31, 2020.2021. As such, our estimates are not necessarily indicative of the amount we could realize in a current market exchange.

Note 87 – 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 (the “2012 Tower Transaction”).years. CCI has fixed-price purchase options for the CCI Lease Sites totaling approximately $2.0 billion, exercisable annually on a per-tranche basis at the end of the lease term.term during the period from December 31, 2035 through December 31, 2049. If CCI exercises its purchase option for any tranche, it must purchase all the towers in the tranche. We lease back a portion of the space at certain tower sites for an initial term of 10 years, followed by optional renewals at customary terms.sites.

Index for Notes to the Condensed Consolidated Financial Statements
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.

Index for Notes to the Condensed Consolidated Financial Statements

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 VIESPEs but are not the primary beneficiary as we lack the power to direct the activities that most significantly impact the Lease Site VIE’sSPEs’ 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.Condensed Consolidated Balance Sheets. 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.obligations. The tower obligations are increased by interest expense and amortized through contractual leaseback payments made by us to CCI and through net cash flows generated and retained by CCI from operation of the tower sites.

Acquired CCI Tower Lease Arrangements

Prior to the Merger,merger (the “Merger”) with Sprint Corporation (“Sprint”), 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.sites.

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.Condensed Consolidated Balance Sheets.

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

The Crown Agreement extends the current term of the leasebacks by up to twelve years and modifies the leaseback payments relatedfor both the Existing CCI Tower Lease Arrangement and the Acquired CCI Tower Lease Arrangement. As a result of the Crown Agreement, there was an increase in our financing obligation as of the effective date of the agreement of approximately $1.2 billion, with a corresponding decrease to Other long-term liabilities associated with unfavorable contract terms. The modification resulted in a revised interest rate under the effective interest method for the tower obligations are approximately $399 millionobligations: 11.6% for the year ending March 31, 2022, $690 million in totalExisting CCI Tower Lease Arrangement and 5.3% for the years ending March 31, 2023 and 2024, $601 million in total for years ending March 31, 2025 and 2026, and $549 million in total for years thereafter.Acquired CCI Tower Lease Arrangement. There were no changes made to either of our master prepaid leases with CCI.

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.

Note 10 – 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 for five to 50 years. In addition, we have financing leases for network equipment that generally have a non-cancelable lease term of three to five years. The financing leases do not have renewal options and contain a bargain purchase option at the end of the lease.

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

Note 11 – Commitments and Contingencies

Purchase Commitments

We have commitments for non-dedicated transportation lines with varying expiration terms that generally extend through 2029.2038. In addition, we have commitments to purchase wireless devices, network services, equipment, software, marketing sponsorship agreements and other items in the ordinary course of business, with various terms through 2043.

Our purchase commitments are approximately $3.9$4.4 billion for the yeartwelve-month period ending March 31, 2022, $4.32023, $5.5 billion in total for each of the yearstwelve-month periods ending March 31, 20232024 and 2024, $2.22025, $2.4 billion in total for each of the yearstwelve-month periods ending March 31, 2025 and 2026 and $1.62027 and $3.1 billion in total for the years 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 certainWe lease spectrum lease contracts from Sprint thatvarious parties. These leases 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. Certain spectrum leases also include purchase options and right-of-first refusal clauses in which we are provided the opportunity to exercise our purchase option if the lessor receives a purchase offer from a third party.The purchase of the leased spectrum is at our option and therefore the option price is not included in the commitments below.

Our spectrum lease and service credit commitments, including renewal periods, are approximately $340 million for the year ending March 31, 2022, $662 million in total for the years ending March 31, 2023 and 2024, $579 million in total for the years ending March 31, 2025 and 2026 and $5.0 billion in total for the years 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 March 31, 2021 was $91 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 proceedingsOur spectrum lease and approvals of the Transactions, we haveservice credit 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 mattersrenewal periods, are approximately $24$345 million for the yeartwelve-month period ending March 31, 2022, $372023, $627 million in total for each of the yearstwelve-month periods ending March 31, 2023 and 2024 and $112025, $623 million in total for each of the yearstwelve-month periods ending March 31, 20252026 and 2026.

Contingencies and Litigation

Litigation and Regulatory Matters

We are involved in various lawsuits and disputes, claims, government agency investigations and enforcement actions, and other proceedings (“Litigation and Regulatory Matters”) that arise in the ordinary course of business, which include claims of patent infringement (most of which are asserted by non-practicing entities primarily seeking monetary damages), class actions, and proceedings to enforce FCC or other government agency rules and regulations. Those Litigation and Regulatory Matters are at various stages, and some of them may proceed to trial, arbitration, hearing, or other adjudication that could result in fines, penalties, or awards of monetary or injunctive relief in the coming 12 months if they are not otherwise resolved. We have established an accrual with respect to certain of these matters, where appropriate, which isappropriate. The accruals are reflected in the condensed consolidated financial statements, but that isthey are not considered to be, individually or in the aggregate, material. An accrual is established when we believe it is both probable that a loss has been incurred and an amount can be reasonably estimated. For other matters, where we have not determined that a loss is probable or because the amount of loss cannot be reasonably estimated, we have not recorded an accrual due to various factors typical in contested proceedings, including, but not limited to, uncertainty concerning legal theories and their resolution by courts or regulators, uncertain damage theories and demands, and a less than fully developed factual record. For Litigation and Regulatory Matters whichthat may result in a contingent gain, we recognize such gains in the condensed consolidated financial statements when the gain is realized or realizable. We recognize legal costs expected to be incurred in connection with Litigation and Regulatory Matters as they are incurred. Except as otherwise specified below, we do not expect that the ultimate resolution of these Litigation and Regulatory Matters, individually or in the aggregate, will have a material adverse effect on our financial position, but we note that an unfavorable outcome of some or all of the specific matters identified below 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 March 31, 2021, which2022, and that accrual was included in Accounts payable and accrued liabilities inon 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. Resolution of these matters could require making additional reimbursements and paying additional fines and penalties.

We note that pursuant to Amendment No. 2, dated as of February 20, 2020, to the Business Combination Agreement, dated as of April 29, 2018, by and among the Company, Sprint and the other parties named therein (as amended, the “Business Combination Agreement”), SoftBank agreed to indemnify us against certain specified matters and losses, including those relating to the Lifeline matters.matters described above. Resolution of these matters could require making additional reimbursements and paying additional fines and penalties, which we do not expect to have a significant impact on our financial results. We expect that any additional liabilities related to these indemnified matters would be indemnified and reimbursed by SoftBank. See

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.

In October 2020, we notified Mobile Virtual Network Operators (“MVNOs”) using the legacy Sprint CDMA network that we

planned to sunset that network on December 31, 2021. In response to that notice, DISH Network Corporation (“DISH”), which has Boost Mobile customers who use the legacy Sprint CDMA network, 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 (the “CPUC”) April 2020 decision concerning the 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 full decommissioning 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 decommissioning. In March 2022, the CPUC denied DISH’s Petition for Modification. We cannot predict the outcome of the other proceedings described above, but we intend to vigorously oppose any efforts to further delay the sunset of the legacy Sprint CDMA network. The orderly decommissioning of the legacy Sprint CDMA network began as planned on March 31, 2022, and is expected to be completed during the second fiscal quarter of 2022, and we will continue to help ensure that DISH and other MVNOs fulfill their contractual responsibilities and transition customers off the legacy Sprint CDMA network before the decommissioning.

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 about March 18, 2021, but only gained access to and took data of current, former, and prospective customers beginning on or about August 3, 2021. With the assistance of our outside cybersecurity experts, we located and closed the unauthorized access to our systems and identified current, former and prospective customers whose information was impacted and notified them, consistent with state and federal requirements. We also undertook a number of other measures to demonstrate our continued support and commitment to data privacy and protection. We also coordinated with law enforcement. Our forensic investigation is complete, and we believe we have a full view of the data compromised.

As a result of the August 2021 cyberattack, we have become subject to numerous lawsuits, including mass arbitration claims and multiple class action lawsuits, that have been filed in numerous jurisdictions seeking unspecified monetary damages, costs and attorneys’ fees arising out of the August 2021 cyberattack. In December 2021, the Judicial Panel on Multidistrict Litigation consolidated the federal class action lawsuits in the U.S. District Court for the Western District of Missouri. In addition, in November 2021, a purported Company shareholder filed a derivative action in the U.S. District Court for the Western District of Washington, Litwin v. Sievert et al., No. 2:21-cv-01599, against our current directors, alleging several claims concerning the Company’s cybersecurity practices. In April 2022, the Litwin case was voluntarily dismissed without prejudice. We are unable to predict at this time the potential outcome of any of the other claims described above or 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 August 2021 cyberattack, which could result in fines or penalties. We are responding to these inquiries and cooperating fully with regulators. However, we cannot predict the timing or outcome of any of these inquiries, or 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.

In March 2022, we received $220 million in settlement of certain patent litigation. We recognized the settlement, net of legal fees, as a reduction to Selling, general and administrative expenses on our Condensed Consolidated Statements of Comprehensive Income.

Note 12 – 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 network infrastructure includingcertain small cell sites and equipmentdistributed antenna systems to achieve synergies in network costs.

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 condensed consolidated 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.

Sprint Merger

Transaction Overview

On April 1, 2020, we completed the Merger with Sprint, a communications company offering a comprehensive rangeTable 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 expect to be able to enhance the breadth and depth of our nationwide 5G network, accelerate innovation, increase competition in the U.S. wireless, video 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 CombinationContents of the Notes to the Condensed Consolidated Financial Statements.

Sprint Merger and Integration Activities

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;operations, migrate customers to the T-Mobile network and billing systems and the impact of legal matters assumed as part of the Merger;
Restructuring costs, including severance, store rationalization and network decommissioning; and
Transaction costs, including legal and professional services related to the completion of the Merger and acquisitions of affiliates.transactions.

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 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.

WeFor full-year 2022, we expect these activities to result in a reduction of expenses withinCost of services andsynergies from Selling, general and administrative expense reductions of $2.3 billion to $2.4 billion and Cost of service expense reductions of $1.6 billion to $1.7 billion.

Other Potential Impacts

The operation of the legacy Sprint CDMA and LTE networks is partially supported by legacy Sprint’s Wireline network acquired through the Merger. We expect that the legacy Sprint CDMA and LTE networks will be decommissioned during 2022. In accordance with ASC 360-10, we assess long-lived assets for impairment when events or circumstances indicate that long-lived assets might be impaired. We expect that the decommissioning of the legacy Sprint CDMA and LTE networks will trigger impairments of certain Wireline long-lived assets as these assets will no longer support our wireless network and the associated customers and cash flows. The potential non-cash impairment charges are not expected to have a material impact on our condensed consolidated financial statements.

Cyberattack

As we previously reported, we were subject to a criminalcyberattack involving unauthorized access to T-Mobile’s systems. We promptly located and closed the unauthorized access to our systems. Our forensic investigation was completed in October 2021, although our Condensed Consolidated Statementsoverall investigation into the incident is ongoing. There are no material updates with respect to the August 2021 cyberattack and subsequent inquiries, investigations, litigations and remedial measures from our Annual Report on Form 10-K for the year ended December 31, 2021, except as disclosed in Note 11 – Commitment and Contingencies. We have incurred certain cyberattack-related expenses that were not material and expect to continue to incur additional expenses in future periods, including costs to remediate the attack, provide additional customer support and enhance customer protection, only some of Comprehensive Income.which may be covered and reimbursable by insurance. We also intend to commit substantial additional resources towards cybersecurity initiatives over the next several years.

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. Throughout this past year,Current and future Pandemic-related restrictions on, or disruptions of, transportation networks and supply chain shortages could impact our ability to acquire handsets or other end user devices in amounts sufficient to meet customer demand and to obtain the Pandemic has peaked, subsidedequipment required to meet our current and seen a resurgence, leading to phased re-openings, as well as continuing or renewed containment measures. The introduction and expanding availability of vaccines, as well as our continued social distancing measures and incremental cleaning efforts, have facilitated the continued operation of our retail stores.future network build-out plans. 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.

For a description of theThe collateral arrangements relating to securities of affiliates that collateralize the Senior Secured Notes please refer toare the same as those described in the section entitled “Affiliates Whose Securities Collateralize the Notes and the Guarantees” in the Company’s Registration Statement on Form S-4/A filed with the SEC on April 21, 2021,22, 2022, which section is incorporated herein by reference.

The assets, liabilities and results of operations of the combined affiliates whose securities are pledged as Collateralcollateral are not materially different than the corresponding amounts presented in the condensed consolidated financial statements of the Company.

Performance Measures

In managing our business and assessing financial performance, we supplement the information provided by our condensed consolidated financial statements with other operating or statistical data and non-GAAP financial measures. These operating and financial measures are utilized by our management to evaluate our operating performance and, in certain cases, our ability to meet liquidity requirements. Although companies in the wireless industry may not define each of these measures in precisely the same way, we believe that these measures facilitate comparisons with other companies in the wireless industry on key operating and financial measures.

The performance measures presented below include the impact of the Merger on a prospective basis from the close date of April 1, 2020. Historical results were not restated.

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.

(2) In the first quarter of 2021, we acquired 11,000 postpaid phone customers and 1,000 postpaid other customers through our acquisition of an affiliate.

Total customers increased 34,894,000, or 51%, primarily from:

Higher postpaid phone customers, primarily due to customers acquired in the Merger and the success of new customer segments and rate plans and continued growth in existing and new markets, along with ongoing promotional activities;
Higher postpaid other customers, primarily due to customers acquired in the Merger and growth in other connected devices, primarily related to public and educational sector customers and wearable products; and
Higher prepaid customers, primarily due to the continued success of our prepaid business due to ongoing promotional activities and rate plan offers, partially offset by customer base adjustments made to align the customer reporting policies of T-Mobile and Sprint.

Customer Base Adjustments

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

(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.

Higher prepaid net customer additions, primarily due to lower churn; and
Higher postpaid other net customer additions, primarily due to expanded retail presence as a result of the Merger, higher gross additions from connected devices, and increased retail store traffic due to closures arising from the Pandemic in the prior period and lower 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:

Adjusted EBITDA and Core Adjusted EBITDA

Beginning in the first quarter of 2021, we are 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. Net income margin represents Net income divided by Service 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 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 and 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”).GAAP.

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.

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 March 31, 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 months ended March 31, 2021, we repaid $55 million 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 March 31, 2021, the outstanding balance under the vendor financing arrangements and other financial liabilities was $186 million, of which $96 million was assumed in connection with the closing of the Merger. As of March 31, 2020, there were no outstanding borrowings under the vendor financing agreements.

We maintain a revolving credit facility (the “Revolving Credit Facility”) with an aggregate commitment amount of $5.5 billion. As of March 31, 2021,2022, 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.

Spectrum Auction

In March 2021,January 2022, the FCC announced that we were the winning bidder of 142199 licenses in Auction 107 (C-band110 (mid-band spectrum) for an aggregate purchase price of $9.3 billion, excluding relocation costs.$2.9 billion. At the inception of Auction 107110 in October 2020,September 2021, we deposited $438$100 million. Upon conclusion of Auction 107 in March 2021, weWe paid the FCC the remaining $8.9$2.8 billion for the licenses won in the auction. We expect to incur an additional $1.2 billionauction in relocation costs which will be paid through 2024.February 2022.

For more information regarding our spectrum licenses, see Note 54 - 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 March 31, 2021,2022, we derecognized net receivables of $2.5 billion upon sale through these arrangements. 

For more information regarding these off-balance sheet arrangements, see Note 43 – 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 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. See “Restructuring” of this MD&A. While we have assumed that a certain level of Merger-related expenses will be incurred, factors beyond our control, including required consultation and negotiation with certain counterparties, could affect the total amount or the timing of these expenses. These expenses could exceed the costs historically borne by us and adversely affect our financial condition and results of operations. There are a number of additional risks and uncertainties, including those due to the impact of the Pandemic, that could cause our financial and operating results and capital requirements to differ materially from our projections, which could cause future liquidity to differ materially from our assessment.

The indentures, supplemental indentures and credit agreements governing our long-term debt to affiliates and third parties, excluding financing leases, contain covenants that, among other things, limit the ability of the Issuers or borrowers and the Guarantor Subsidiaries to incur more debt, 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 March 31, 2021.2022.

Shentel Wireless Asset Acquisition

Sprint PCS (specifically Sprint Spectrum L.P.) is party to a variety of publicly filed agreements with Shentel, pursuant to which Shentel is 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 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. T-Mobile’s exercise of its option triggered a requirement for the parties to engage three independent valuation providers to calculate the “entire business value” (the “Entire Business Value”) of such wireless telecommunications assets, pursuant to a formula and valuation process prescribed in the Management Agreement.

On February 1, 2021, in accordance with the Management Agreement and other agreed-upon terms, the Entire Business Value of Shentel’s wireless telecommunications assets used to provide services pursuant to the Management Agreement was determined to be $2.1 billion, and correspondingly, the base purchase price for such wireless telecommunications assets shall be ninety percent (90%) of that Entire Business Value amount ($1.9 billion), subject to certain other purchase price adjustments prescribed by the Management Agreement and such additional purchase price adjustments agreed by the parties. The parties are negotiating the remaining outstanding terms of a definitive agreement to govern the purchase of Shentel’s wireless telecommunication assets and expect the transaction to close in the third quarter of 2021 after satisfying customary conditions to closing.

Financing Lease Facilities

We have entered into uncommitted financing lease facilities with certain partnersthird parties that provide us with the ability to enter into financing leases for network equipment and services. As of March 31, 2021,2022, we have committed to $5.2$6.6 billion of financing leases under these financing lease facilities, of which $108$299 million was executed during the three months ended March 31, 2021.2022. We expect to enter into up to an additional $1.1 billion$901 million in financing lease commitments during the year ending December 31, 2021.2022.

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 pending acquisition of C-band licenses won in Auction 107, acquired Sprint PCS and 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.

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

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

Our Fifth AmendedCyberattacks against companies like ours have increased in frequency 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 lawspotential harm over time, and the rulesmethods used to gain unauthorized access constantly evolve, making it increasingly difficult to anticipate, prevent, and/or detect incidents successfully in every instance. They are perpetrated by a variety of groups and regulations thereunder. Moreover,persons, including state-sponsored parties, malicious actors, employees, contractors, or other unrelated third parties. Some of these persons reside in jurisdictions where law enforcement measures to address such attacks are ineffective or unavailable, and such attacks may even be perpetrated by or at the provision does not apply to suits brought to enforce a duty or liability created by the Exchange Act or by the Securities Actbehest of 1933, as amended.foreign governments.

This choiceIn addition, we routinely provide certain Confidential Information to third-party providers whose products and services are used in our business operations, including as part of forum provision may increase costsour IT systems, such as cloud services. These third-party providers have experienced in the past, and will continue to bring a claim, discourage claims experience in the future, cyberattacks that involve attempts to obtain unauthorized access to our Confidential Information and/or limit a stockholder’s ability to bring a claim in a judicial forumcreate operational disruptions 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 these providers also face other security challenges common to all parties that collect and process information.

In August 2021, we disclosed that our systems were subject to a criminal cyberattack that compromised certain data of millions of our current customers, former customers, and prospective customers, including, in some instances, social security numbers, names, addresses, dates of birth and driver’s license/identification numbers. With the assistance of outside cybersecurity experts, we located and closed the unauthorized access to our systems and identified current, former, and prospective customers whose information was impacted and notified them, consistent with state and federal requirements. We have incurred certain cyberattack-related expenses, including costs to remediate the attack, provide additional customer support and enhance customer protection, and expect to incur additional expense in future periods resulting from the attack. For more information, see “Cyberattack” in the Overview section of MD&A. As a result of the August 2021 cyberattack, we are subject to numerous claims, lawsuits and regulatory inquiries, the ongoing costs of which may be material, and we may be subject to further regulatory inquiries and private litigation. For more information, see “– Contingencies and Litigation – Litigation and Regulatory Matters” in Note 11 – Commitments and Contingencies of the Notes to the Consolidated Financial Statements.” As a result of the August 2021 cyberattack, we may incur significant costs or experience other material financial condition.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 experienced other unrelated immaterial incidents involving unauthorized access to certain Confidential Information. Typically, these incidents have involved attempts to commit fraud by taking control of a customer’s phone line, often by using compromised credentials. In other cases, the incidents have involved unauthorized access to certain of our customers’ private information, including credit card information, financial data, social security numbers or passwords, and to certain of our intellectual property.

Our procedures and safeguards to prevent unauthorized access to Confidential Information and to defend against cyberattacks seeking to disrupt our operations must be continually evaluated and enhanced to address the ever-evolving threat landscape and changing cybersecurity regulations. These preventative actions require the investment of significant resources and management time and attention. Additionally, we do not have control of the cybersecurity systems, breach prevention, and response protocols of our third-party providers. While T-Mobile may have contractual rights to assess the effectiveness of many of our providers’ systems and protocols, we do not have the means to know or assess the effectiveness of all of our providers’ systems and controls at all times. We cannot provide any assurances that actions taken by us, or our third-party providers will adequately repel a significant cyberattack or prevent or substantially mitigate the impacts of cybersecurity breaches or misuses of Confidential Information, unauthorized access to our networks or systems or exploits against third-party environments, or that we or our third-party providers, will be able to effectively identify, investigate, and remediate such incidents in a timely manner or at all. We expect to continue to be the target of cyberattacks, given the nature of our business, and we expect the same with respect to our third-party providers. Our inability to protect Confidential Information or to prevent operational disruptions from future cyberattacks may have a material adverse effect on our business, reputation, financial condition, cash flows, and operating results.
