Notes to the Condensed Consolidated Financial Statements

Note 1 – Summary of Significant Accounting Policies

Basis of Presentation

The unaudited condensed consolidated financial statements of T-Mobile US, Inc. (“T-Mobile,” “we,” “our,” “us” or the “Company”) include all adjustments of a normal recurring nature necessary for the fair presentation of the results for the interim periods presented. The results for the interim periods are not necessarily indicative of those for the full year. The condensed consolidated financial statements should be read in conjunction with our consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2022.

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. Estimates are inherently subject to judgment and actual results could differ from those estimates.

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

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

Dividends

On September 6, 2023, our Board of Directors authorized a stockholder return program of up to $19.0 billion that will run through December 31, 2024 (the “2023-2024 Stockholder Return Program”). The 2023-2024 Stockholder Return Program is expected to consist of additional repurchases of shares of our common stock and the payment of cash dividends. The amount available under the 2023-2024 Stockholder Return Program for share repurchases will be reduced by the amount of any cash dividends declared by us.

Dividends declared are included as a reduction to Retained earnings on our Condensed Consolidated Balance Sheets. We recognize a liability for dividends declared but for which cash has not been paid in Other current liabilities on our Condensed Consolidated Balance Sheets. Dividend cash payments to stockholders will be included in Net cash (used in) provided by financing activities on our Condensed Consolidated Statements of Cash Flows. See Note 10 - Stockholder Return Programs for more information about our 2023-2024 Stockholder Return Program.

Accounting Pronouncements Adopted During the Current Year

Troubled Debt Restructurings and Vintage Disclosures

In March 2022, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2022-02, “Financial Instruments—Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures.” The standard eliminates the accounting guidance within ASC 310-40 for troubled debt restructurings by creditors while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty. Additionally, for public business entities, the standard requires disclosure of current-period gross write-offs by year of origination for financing receivables and net investments in leases within the scope of ASC 326-20. As of January 1, 2023, we have adopted this standard, and it was applied prospectively after this date. This standard did not have a material impact on our condensed consolidated financial statements as of and for the three and nine months ended September 30, 2023.

On March 9, 2023, we entered into a Merger and Unit Purchase Agreement for the acquisition of 100% of the outstanding equity of Ka’ena Corporation and its subsidiaries including, among others, Mint Mobile LLC, for a maximum purchase price of $1.35 billion to be paid out 39% in cash and 61% in shares of T-Mobile common stock. The purchase price is variable dependent upon specified performance indicators of Ka’ena Corporation during certain periods before and after closing and consists of an upfront payment at closing of the transaction, subject to certain agreed-upon adjustments, and a variable earnout payable 24 months after closing of the transaction. Our estimate of the upfront payment is subject to Ka’ena Corporation’s underlying business performance and the timing of transaction close, and has been updated to $1.2 billion, before working capital adjustments. The acquisition is subject to certain customary closing conditions, including certain regulatory approvals, and is expected to close by the end of the first quarter of 2024.

Note 3 – Receivables and Related Allowance for Credit Losses

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

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

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

Accounts Receivable Portfolio Segment

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

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

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

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

10

EIP Receivables Portfolio Segment

Based upon customer credit profiles at the time of customer origination, we classify the EIP receivables segment into two customer classes of “Prime” and “Subprime.” Prime customer receivables are those with lower credit risk and Subprime customer receivables are those with higher credit risk. Customers may be required to make a down payment on their equipment purchases if their assessed credit risk exceeds established underwriting thresholds. In addition, certain customers within the Subprime category may be required to pay a deposit.

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

EIP receivables had a combined weighted-average effective interest rate of 9.9% and 8.0% as of September 30, 2023, and December 31, 2022, respectively.

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

(in millions)	September 30, 2023		December 31, 2022
EIP receivables, gross	$	7,089	$	8,480
Unamortized imputed discount	(453)		(483)
EIP receivables, net of unamortized imputed discount	6,636		7,997
Allowance for credit losses	(287)		(328)
EIP receivables, net of allowance for credit losses and imputed discount	$	6,349	$	7,669
Classified on our condensed consolidated balance sheets as:
Equipment installment plan receivables, net of allowance for credit losses and imputed discount	$	4,470	$	5,123
Equipment installment plan receivables due after one year, net of allowance for credit losses and imputed discount	1,879		2,546
EIP receivables, net of allowance for credit losses and imputed discount	$	6,349	$	7,669

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

The following table presents the amortized cost of our EIP receivables by delinquency status, customer credit class and year of origination as of September 30, 2023:

	Originated in 2023				Originated in 2022				Originated prior to 2022				Total EIP Receivables, Net of Unamortized Imputed Discounts
(in millions)	Prime		Subprime		Prime		Subprime		Prime		Subprime		Prime		Subprime		Total
Current - 30 days past due	$	2,419	$	1,355	$	1,305	$	896	$	368	$	175	$	4,092	$	2,426	$	6,518
31 - 60 days past due	8		18		7		12		2		2		17		32		49
61 - 90 days past due	5		12		5		10		1		1		11		23		34
More than 90 days past due	5		9		5		11		2		3		12		23		35
EIP receivables, net of unamortized imputed discount	$	2,437	$	1,394	$	1,322	$	929	$	373	$	181	$	4,132	$	2,504	$	6,636

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

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

Off-Balance-Sheet Credit Exposures

We do not have material off-balance-sheet credit exposures as of September 30, 2023. In connection with the sales of certain service accounts receivable and EIP receivables pursuant to the sale arrangements, we have deferred purchase price assets included on our Condensed Consolidated Balance Sheets measured at fair value that are based on a discounted cash flow model using Level 3 inputs, including customer default rates and credit worthiness, dilutions and recoveries. See Note 4 – Sales of Certain Receivables for further information.

Note 4 – Sales of Certain Receivables

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

Sales of EIP Receivables

Overview of the Transaction

In 2015, we entered into an arrangement to sell certain EIP receivables on a revolving basis (the “EIP sale arrangement”), which has been revised and extended from time to time. As of both September 30, 2023, and December 31, 2022, the EIP sale arrangement provided funding of $1.3 billion.

In connection with this EIP sale arrangement, we formed a wholly owned subsidiary, which qualifies as a bankruptcy remote entity (the “EIP BRE”). We consolidate the EIP BRE under the VIE model.

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

(in millions)	September 30, 2023		December 31, 2022
Other current assets	$	368	$	344
Other assets	114		136

12

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”). On February 28, 2023, we extended the scheduled expiration date of the service receivable sale arrangement to February 27, 2024. As of both September 30, 2023, and December 31, 2022, the service receivable sale arrangement provided funding of $775 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”). We consolidate the Service BRE under the VIE model.

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

(in millions)	September 30, 2023		December 31, 2022
Other current assets	$	210	$	214
Other current liabilities	355		389

Sales of Receivables

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

(in millions)	September 30, 2023		December 31, 2022
Derecognized net service accounts receivable and EIP receivables	$	2,426	$	2,410
Other current assets	578		558
of which, deferred purchase price	576		556
Other long-term assets	114		136
of which, deferred purchase price	114		136
Other current liabilities	355		389
Net cash proceeds since inception	1,604		1,697
Of which:
Change in net cash proceeds during the year-to-date period	(93)		(57)
Net cash proceeds funded by reinvested collections	1,697		1,754

At inception, we elected to measure the deferred purchase price at fair value with changes in fair value included in Selling, general and administrative expenses on 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 estimated customer default rates. As of September 30, 2023, and December 31, 2022, our deferred purchase price related to the sales of service accounts receivable and EIP receivables was $690 million and $692 million, respectively.

We recognized losses from sales of receivables, including changes in fair value of the deferred purchase price, of $46 million and $60 million for the three months ended September 30, 2023 and 2022, respectively, and $135 million and $168 million for the nine months ended September 30, 2023 and 2022, respectively, in Selling, general and administrative expenses on our Condensed Consolidated Statements of Comprehensive Income.

Continuing Involvement

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

13

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.

Note 5 – Spectrum License Transactions

The following table summarizes our spectrum license activity for the nine months ended September 30, 2023:

(in millions)	2023
Spectrum licenses, beginning of year	$	95,798
Spectrum license acquisitions	85
Spectrum licenses transferred to held for sale	(2)
Costs to clear spectrum (1)	808
Spectrum licenses, end of period	$	96,689

(1)As of September 30, 2023, $767 million is included in Other current liabilities on our Condensed Consolidated Balance Sheets related to accrued spectrum clearing costs.

Cash payments to acquire spectrum licenses and payments for costs to clear spectrum are included in Purchases of spectrum licenses and other intangible assets, including deposits, on our Condensed Consolidated Statements of Cash Flows for the three and nine months ended September 30, 2023.

Spectrum Transactions

In September 2022, the Federal Communications Commission (“FCC”) announced that we were the winning bidder of 7,156 licenses in Auction 108 (2.5 GHz spectrum) for an aggregate price of $304 million. At inception of Auction 108 in June 2022, we deposited $65 million. We paid the FCC the remaining $239 million for the licenses won in the auction in September 2022. The aggregate cash payments made to the FCC are included in Other assets on our Condensed Consolidated Balance Sheets as of September 30, 2023, and will remain there until the corresponding licenses are received. The timing of when the licenses will be issued will be determined by the FCC after all post-auction procedures have been completed, and the FCC Chairwoman has stated that it is subject to the restoration of auction authority to the FCC by Congress.

As of September 30, 2023, the activities that are necessary to get the 3.45 GHz and 2.5 GHz spectrum, acquired pursuant to FCC Auctions 110 and 108, ready for its intended use have not begun; as such, capitalization of the interest associated with the costs of deploying these spectrum licenses has not begun. During the three months ended September 30, 2023, we began capitalizing interest on the costs of our C-band spectrum licenses, acquired pursuant to FCC Auction 107, as we have begun development activities necessary to prepare the spectrum for its intended use.

License Purchase Agreements

DISH Network Corporation

On July 1, 2020, we and DISH Network Corporation (“DISH”) entered into a license purchase agreement (the “DISH License Purchase Agreement”) pursuant to which DISH agreed to purchase certain 800 MHz spectrum licenses for a total of approximately $3.6 billion. The closing of the sale of spectrum under the DISH License Purchase Agreement remains subject to FCC approval. Subsequent to September 30, 2023, on October 15, 2023, we and DISH entered into an amendment (the “LPA Amendment”) to the DISH License Purchase Agreement pursuant to which, among other things, the parties agreed that (1) DISH will pay us a $100 million non-refundable extension fee (in lieu of the approximately $72 million termination fee that had previously been agreed to), (2) the closing for the purchase of the spectrum licenses by DISH will occur no later than April 1, 2024, (3) if DISH has not purchased the spectrum licenses by such date for any reason (including failure to receive the required FCC approval prior to such date), then the DISH License Purchase Agreement will automatically terminate, and we will retain the $100 million extension fee, (4) if DISH does purchase the spectrum by April 1, 2024, the $100 million extension fee will be credited against the $3.6 billion purchase price, and (5) permits us to commence auction of the spectrum prior to April 1, 2024 at our discretion (and subject to DISH’s purchase right). The LPA Amendment was approved by the Court and became effective on October 23, 2023.

If DISH does not, by April 1, 2024, purchase the 800 MHz spectrum licenses, we are required, unless otherwise approved under the final judgment agreed to by us, Deutsche Telekom AG (“DT”), Sprint Corporation, now known as Sprint LLC (“Sprint”), SoftBank Group Corp. (“SoftBank”) and DISH with the U.S. District Court for the District of Columbia, which was approved by the Court on April 1, 2020, to offer the licenses for sale through an auction. If the specified minimum price of $3.6 billion is not met in the auction, we would be relieved of the obligation to sell the licenses.

14

Channel 51 License Co LLC and LB License Co, LLC

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

On March 30, 2023, we and the Sellers entered into Amended and Restated License Purchase Agreements pursuant to which we and the Sellers agreed to separate the transaction into two tranches of licenses, with the closings on the acquisitions of certain licenses in Chicago, Dallas and New Orleans being deferred in order to potentially expedite the regulatory approval process for the remainder of the licenses. Subsequently, on August 25, 2023, we and the Sellers entered into Amendments No. 1 to the Amended and Restated License Purchase Agreements, which deferred the closings of certain additional licenses in Chicago and Dallas into the second closing tranche. Together, the licenses with closings deferred into the second closing tranche represent $1.1 billion of the aggregate $3.5 billion cash consideration. The licenses being acquired by us, and the total consideration being paid for the licenses, remains the same under the original License Purchase Agreements and subsequent amendments.

We anticipate that the first closing will occur no earlier than the first half of 2024 and that the second closing (on the deferred licenses) will occur in late 2024 or early 2025.

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

Comcast Corporation

On September 12, 2023, we entered into a License Purchase Agreement with Comcast Corporation and its affiliate, Comcast OTR1, LLC (together with Comcast Corporation, “Comcast”), pursuant to which we will acquire spectrum in the 600 MHz band from Comcast in exchange for total cash consideration of between $1.2 billion and $3.3 billion, subject to an application for FCC approval. The licenses will be acquired without any associated networks. We anticipate the closing will occur in the first half of 2028.

The final purchase price will be determined, in the aggregate and on a per license basis, based on the set of licenses subject to the License Purchase Agreement at the time the parties make required transfer filings with the FCC. Prior to the time of such filings, Comcast has the right to remove any or all of a certain specified subset of the licenses, totaling $2.1 billion (the “Optional Sale Licenses”), from the License Purchase Agreement. The removal of any Optional Sale Licenses would reduce the final purchase price by the assigned value of each such license, from the maximum purchase price of $3.3 billion.

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

Note 6 – Fair Value Measurements

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

Derivative Financial Instruments

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

15

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

We did not have any significant derivative instruments outstanding as of September 30, 2023, or December 31, 2022.

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 $1.2 billion and $1.3 billion are presented in Accumulated other comprehensive loss on our Condensed Consolidated Balance Sheets as of September 30, 2023, and December 31, 2022, respectively.

For the three months ended September 30, 2023 and 2022, $55 million and $51 million, respectively, and for the nine months ended September 30, 2023 and 2022, $163 million and $151 million, respectively, were amortized from Accumulated other comprehensive loss into Interest expense, net, on our Condensed Consolidated Statements of Comprehensive Income. We expect to amortize $232 million of the Accumulated other comprehensive loss associated with the derivatives into Interest expense, net, over the 12 months ending September 30, 2024.

Deferred Purchase Price Assets

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

The carrying amounts of our deferred purchase price assets, which are measured at fair value on a recurring basis and are included on our Condensed Consolidated Balance Sheets, were $690 million and $692 million as of September 30, 2023, and December 31, 2022, respectively.

Debt

The fair value of our Senior Notes and spectrum-backed 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. The fair value of our asset-backed notes (“ABS Notes”) was primarily based on quoted prices in inactive markets for identical instruments and observable changes in market interest rates, both of which are Level 2 inputs. Accordingly, our ABS Notes were classified as Level 2 within the fair value hierarchy.

Although we have determined the estimated fair values using available market information and commonly accepted valuation methodologies, considerable judgment was required in interpreting market data to develop fair value estimates for the Senior Notes to affiliates and ABS Notes. The fair value estimates were based on information available as of September 30, 2023, and December 31, 2022. As such, our estimates are not necessarily indicative of the amount we could realize in a current market exchange.

16

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

(in millions)	Level within the Fair Value Hierarchy	September 30, 2023				December 31, 2022
		Carrying Amount		Fair Value		Carrying Amount (1)		Fair Value (1)
Liabilities:
Senior Notes to third parties	1	$	70,542	$	61,198	$	66,582	$	59,011
Senior Notes to affiliates	2	1,496		1,439		1,495		1,460
Senior Secured Notes to third parties	1	2,513		2,407		3,117		2,984
ABS Notes to third parties	2	747		739		746		744

(1)     Excludes $20 million as of December 31, 2022, in other financial liabilities as the carrying values approximate fair value, primarily due to the short-term maturities of these instruments.

(1)Issuances and borrowings, note redemptions and reclassifications are recorded net of accrued or paid issuance costs, discounts and premiums.

(2)Other includes the amortization of premiums, discounts, debt issuance costs and consent fees.

Our effective interest rate, excluding the impact of derivatives and capitalized interest, was approximately 4.0% and 3.8% on weighted-average debt outstanding of $77.2 billion and $71.6 billion for the three months ended September 30, 2023 and 2022, respectively, and 4.0% and 3.9% on weighted-average debt outstanding of $75.5 billion and $72.4 billion for the nine months ended September 30, 2023 and 2022, respectively. The weighted-average debt outstanding was calculated by applying an average of the monthly ending balances of total short-term and long-term debt to third parties and short-term and long-term debt to affiliates, net of unamortized premiums, discounts, debt issuance costs and consent fees.

In connection with issuing the ABS Notes in October 2022, we formed a wholly owned subsidiary, which qualifies as a bankruptcy remote entity (the “ABS BRE”), and a trust (the “ABS Trust” and together with the ABS BRE, the “ABS Entities”), in which the ABS BRE holds a residual interest. The ABS Entities meet the definition of a VIE for which we have determined that we are the primary beneficiary as we have the power to direct the activities of the ABS Entities that most significantly impact their performance. Accordingly, we include the balances and results of operations of the ABS Entities in our condensed consolidated financial statements.

The following table summarizes the carrying amounts and classification of assets and liabilities included in our Condensed Consolidated Balance Sheets with respect to the ABS Entities:

(in millions)	September 30, 2023		December 31, 2022
Assets
Equipment installment plan receivables, net	$	767	$	652
Equipment installment plan receivables due after one year, net	151		281
Other current assets	94		73
Liabilities
Accounts payable and accrued liabilities	$	1	$	1
Long-term debt	747		746

See Note 3 – Receivables and Related Allowance for Credit Losses for additional information on the EIP receivables used to secure the ABS Notes.

Restricted Cash

Certain provisions of our debt agreements require us to maintain specified cash collateral balances. Amounts associated with these balances are considered to be restricted cash. See Note 15 - Additional Financial Information for our reconciliation of Cash and cash equivalents, including restricted cash and cash held for sale.

Commercial Paper

On July 25, 2023, we established an unsecured short-term commercial paper program with the ability to borrow up to $2.0 billion from time to time. This program supplements our other available external financing arrangements, and proceeds are expected to be used for general corporate purposes. As of September 30, 2023, there was no outstanding balance under this program.

Note 8 – Tower Obligations

Existing CCI Tower Lease Arrangements

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

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

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

However, we also considered if this arrangement resulted in the sale of the CCI Lease Sites for which we would derecognize the tower assets. By assessing whether control had transferred, we concluded that transfer of control criteria, as discussed in the revenue standard, were not met. Accordingly, we recorded this arrangement as a financing whereby we recorded debt, a financial obligation, and the CCI Lease Sites tower assets remained on our 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. The tower obligations are increased by interest expense and amortized through contractual leaseback payments made by us to CCI and through net cash flows generated and retained by CCI from the operation of the tower sites.

Acquired CCI Tower Lease Arrangements

Prior to our merger (the “Merger”) with 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.

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

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

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

19

Leaseback Arrangement

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

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

(in millions)	September 30, 2023		December 31, 2022
Property and equipment, net	$	2,259	$	2,379
Tower obligations	3,819		3,934
Other long-term liabilities	554		554

Future minimum payments related to the tower obligations are approximately $432 million for the 12-month period ending September 30, 2024, $780 million in total for both of the 12-month periods ending September 30, 2025 and 2026, $804 million in total for both of the 12-month periods ending September 30, 2027 and 2028, and $4.2 billion in total thereafter.

We are contingently liable for future ground lease payments through the remaining term of the CCI Lease Sites and the Master Lease Sites. These contingent obligations are not included in Operating lease liabilities as any amount due is contractually owed by CCI based on the subleasing arrangement. Under the arrangement, we remain primarily liable for ground lease payments on approximately 900 sites and have included lease liabilities of $244 million in our Operating lease liabilities as of September 30, 2023.

Note 9 – Revenue from Contracts with Customers

Disaggregation of Revenue

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

•Postpaid customers generally include customers who are qualified to pay after receiving wireless communications services utilizing phones, High Speed Internet, mobile internet devices, including tablets and hotspots, wearables, DIGITS or other connected devices, including SyncUP and IoT;

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

•Wholesale customers include Machine-to-Machine and Mobile Virtual Network Operator customers that operate on our network but are managed by wholesale partners.

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

	Three Months Ended September 30,				Nine Months Ended September 30,
(in millions)	2023		2022		2023		2022
Postpaid service revenues
Postpaid phone revenues	$	10,942	$	10,481	$	32,393	$	31,119
Postpaid other revenues	1,346		1,067		3,827		3,075
Total postpaid service revenues	$	12,288	$	11,548	$	36,220	$	34,194

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

20

Contract Balances

The contract asset and contract liability balances from contracts with customers as of September 30, 2023, and December 31, 2022, were as follows:

(in millions)	Contract Assets		Contract Liabilities
Balance as of December 31, 2022	$	534	$	748
Balance as of September 30, 2023	617		814
Change	$	83	$	66

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

Contract asset balances increased primarily due to an increase in promotions with an extended service contract, partially offset by billings on existing contracts and impairment, which is recognized as bad debt expense. The current portion of our contract assets of approximately $490 million and $356 million as of September 30, 2023, and December 31, 2022, respectively, was included in Other current assets on our Condensed Consolidated Balance Sheets.

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

Revenues for the three and nine months ended September 30, 2023 and 2022 include the following:

	Three Months Ended September 30,				Nine Months Ended September 30,
(in millions)	2023		2022		2023		2022
Amounts included in the beginning of year contract liability balance	$	24	$	17	$	730	$	702

Remaining Performance Obligations

As of September 30, 2023, the aggregate amount of transaction price allocated to remaining service performance obligations for postpaid contracts with subsidized devices and promotional bill credits that result in an extended service contract is $1.5 billion. We expect to recognize revenue as the service is provided on these postpaid contracts over an extended contract term of 24 months from the time of origination.

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

Certain of our wholesale, roaming and service contracts include variable consideration based on usage and performance. This variable consideration has been excluded from the disclosure of remaining performance obligations. As of September 30, 2023, the aggregate amount of the contractual minimum consideration for wholesale, roaming and service contracts is $395 million, $2.0 billion and $4.2 billion for 2023, 2024, and 2025 and beyond, respectively. These contracts have a remaining duration ranging from less than one year to eight years.

Contract Costs

The balance of deferred incremental costs to obtain contracts with customers was $2.1 billion and $1.9 billion as of September 30, 2023, and December 31, 2022, respectively, and is included in Other assets on our Condensed Consolidated Balance Sheets. Deferred contract costs incurred to obtain postpaid service contracts are amortized over a period of 24 months. The amortization period is monitored to reflect any significant change in assumptions. Amortization of deferred contract costs included in Selling, general and administrative expenses on our Condensed Consolidated Statements of Comprehensive Income were $468 million and $375 million for the three months ended September 30, 2023 and 2022, respectively, and $1.3 billion and $1.1 billion for the nine months ended September 30, 2023 and 2022, respectively.

The deferred contract cost asset is assessed for impairment on a periodic basis. There were no impairment losses recognized on deferred contract cost assets for the three and nine months ended September 30, 2023 and 2022.

Note 10 – Stockholder Return Programs

2022 Stock Repurchase Program

On September 8, 2022, our Board of Directors authorized our 2022 Stock Repurchase Program for up to $14.0 billion of our common stock through September 30, 2023 (the “2022 Stock Repurchase Program”). During the three months ended September 30, 2023, we repurchased 19,313,159 shares of our common stock at an average price per share of $138.48 for a total purchase price of $2.7 billion, and during the nine months ended September 30, 2023, we repurchased 77,460,937 shares of our common stock at an average price per share of $141.57 for a total purchase price of $11.0 billion, all of which were purchased under the 2022 Stock Repurchase Program. All shares purchased during the nine months ended September 30, 2023, were purchased at market price.

2023-2024 Stockholder Return Program

On September 6, 2023, our Board of Directors authorized our 2023-2024 Stockholder Return Program of up to $19.0 billion that will run through December 31, 2024. The 2023-2024 Stockholder Return Program is expected to consist of additional repurchases of shares of our common stock and the payment of cash dividends. The amount available under the 2023-2024 Stockholder Return Program for share repurchases will be reduced by the amount of any cash dividends declared by us.

Under the 2023-2024 Stockholder Return Program, share repurchases can be made from time to time using a variety of methods, which may include open market purchases, Rule 10b5-1 plans, accelerated share repurchases, privately negotiated transactions or otherwise, all in accordance with the rules of the Securities and Exchange Commission and other applicable legal requirements. The specific timing and amount of any share repurchases, and the specific timing and amount of any dividend payments, under the 2023-2024 Stockholder Return Program will depend on prevailing share prices, general economic and market conditions, Company performance, and other considerations. In addition, the specific timing and amount of any dividend payments are subject to being declared on future dates by our Board of Directors in its sole discretion. The 2023-2024 Stockholder Return Program does not obligate us to acquire any particular amount of common stock or to declare and pay any particular amount of dividends, and the 2023-2024 Stockholder Return Program may be suspended or discontinued at any time at our discretion.

On September 25, 2023, our Board of Directors declared a cash dividend of $0.65 per share on our issued and outstanding common stock, which is payable on December 15, 2023, to stockholders of record as of the close of business on December 1, 2023. As of September 30, 2023, $745 million for dividends payable is presented within Other current liabilities on our Condensed Consolidated Balance Sheets, of which $393 million is payable to DT.

During the three and nine months ended September 30, 2023, we did not repurchase any shares of our common stock under the 2023-2024 Stockholder Return Program. As of September 30, 2023, we had up to $18.3 billion remaining under the 2023-2024 Stockholder Return Program.

Subsequent to September 30, 2023, from October 1, 2023, through October 20, 2023, we repurchased 5,515,568 shares of our common stock at an average price per share of $139.76 for a total purchase price of $771 million. As of October 20, 2023, we had up to $17.5 billion remaining under the 2023-2024 Stockholder Return Program.

Note 11 – Wireline

Sale of the Wireline Business

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

On May 1, 2023, pursuant to the Wireline Sale Agreement, upon the terms and subject to the conditions thereof, we completed the Wireline Transaction. Under the terms of the Wireline Sale Agreement, the parties agreed to a $1 purchase price in consideration for the Purchased Interests, subject to customary adjustments, as well as payments to the Buyer pursuant to an IP transit services agreement totaling $700 million, consisting of (i) $350 million in equal monthly installments during the first year after the Closing and (ii) $350 million in equal monthly installments over the subsequent 42 months. The Buyer paid the

22

Company $61 million at Closing. The Closing of the Wireline Transaction did not have a significant impact on the Loss (gain) on disposal group held for sale on our Condensed Consolidated Statements of Comprehensive Income.

The present value of the $700 million liability for fees payable for IP transit services was recognized and treated as part of the consideration exchanged with the Buyer to complete the disposal transaction, as there is a remote likelihood we will use any more than a de minimis amount of the services under the IP transit services agreement. Therefore, we concluded the cash payment obligations under the IP transit services agreement were part of the consideration paid to the Buyer to facilitate the sale of the Wireline Business, and therefore, included in measuring the fair value less costs to sell of the Wireline Business disposal group. As of September 30, 2023, $246 million and $275 million of this liability, including accrued interest, is presented within Other current liabilities and Other long-term liabilities, respectively, on our Condensed Consolidated Balance Sheets in accordance with the expected timing of the related payments. As of September 30, 2023, $30 million and $31 million for contractual and other payments associated with the Wireline Transaction are presented within Other current liabilities and Other long-term liabilities, respectively, on our Condensed Consolidated Balance Sheets in accordance with the expected timing of the related payments.

We recognized a pre-tax gain of $25 million during the nine months ended September 30, 2023, and a pre-tax loss of $1.1 billion during the three and nine months ended September 30, 2022, which are included within Loss (gain) on disposal group held for sale on our Condensed Consolidated Statements of Comprehensive Income. There was no gain or loss on disposal group held for sale for the three months ended September 30, 2023.

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

2022 Wireline Impairment

During the second quarter of 2022, we determined that the retirement of the legacy Sprint CDMA and LTE wireless networks triggered the need to assess the Wireline long-lived assets for impairment, as these assets no longer support our wireless network and the associated customers and cash flows in a significant manner. The results of this assessment indicated that certain Wireline long-lived assets were impaired, and as a result, we recorded noncash impairment expense of $477 million during the nine months ended September 30, 2022, all of which relates to the impairment recognized during the three months ended June 30, 2022, of which $258 million was related to Wireline Property and equipment, $212 million was related to Operating lease right-of-use assets and $7 million was related to Other intangible assets. The expense is included within Impairment expense on our Condensed Consolidated Statements of Comprehensive Income. There was no impairment expense recognized for the three and nine months ended September 30, 2023.

Note 12 – Earnings Per Share

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

	Three Months Ended September 30,				Nine Months Ended September 30,
(in millions, except shares and per share amounts)	2023		2022		2023		2022
Net income	$	2,142	$	508	$	6,303	$	1,113
Weighted-average shares outstanding – basic	1,171,336,373		1,253,873,429		1,194,497,722		1,252,783,140
Effect of dilutive securities:
Outstanding stock options and unvested stock awards	3,054,099		5,336,842		3,792,419		5,278,338
Weighted-average shares outstanding – diluted	1,174,390,472		1,259,210,271		1,198,290,141		1,258,061,478

SoftBank contingent consideration (1)	48,751,557		48,751,557		48,751,557		48,751,557

(1)     Represents the weighted-average SoftBank Specified Shares Amount that is contingently issuable from the Merger date of April 1, 2020, pursuant to a letter agreement dated February 20, 2020, between T-Mobile, SoftBank and DT (the “Letter Agreement”).

23

As of September 30, 2023, we had authorized 100 million shares of preferred stock, with a par value of $0.00001 per share. There was no preferred stock outstanding as of September 30, 2023 and 2022. Potentially dilutive securities were not included in the computation of diluted earnings per share if to do so would have been anti-dilutive.

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

The issuance of the SoftBank Specified Shares Amount is contingent on the trailing 45-trading-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 (the “Threshold Price”), at any time during the period commencing on April 1, 2022, and ending on December 31, 2025 (the “Measurement Period”). In accordance with the terms of the Letter Agreement, the Threshold Price is subject to downward adjustment by the per share amount of any cash dividends or other cash distributions declared or paid on our common stock during the Measurement Period. As of September 30, 2023, the Threshold Price is $149.35 and will automatically further adjust upon the declaration of any future cash dividends as provided in the Letter Agreement.

Note 13 – Commitments and Contingencies

Purchase Commitments

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

Our purchase commitments are approximately $4.7 billion for the 12-month period ending September 30, 2024, $4.3 billion in total for both of the 12-month periods ending September 30, 2025 and 2026, $2.7 billion in total for both of the 12-month periods ending September 30, 2027 and 2028, and $2.3 billion in total thereafter. These amounts are not reflective of our entire anticipated purchases under the related agreements but are determined based on the non-cancelable quantities or termination amounts to which we are contractually obligated.

On March 9, 2023, we entered into a Merger and Unit Purchase Agreement for the acquisition of 100% of the outstanding equity of Ka’ena Corporation and its subsidiaries including, among others, Mint Mobile LLC, for a maximum purchase price of $1.35 billion to be paid out 39% in cash and 61% in shares of T-Mobile common stock. Our estimate of the upfront payment is subject to Ka’ena Corporation’s underlying business performance and the timing of transaction close, and has been updated to $1.2 billion, before working capital adjustments. The agreement remains subject to regulatory approval, and the estimated purchase price is excluded from our reported purchase commitments above. See Note 2 – Business Combination for additional details.

Spectrum Leases

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

Our spectrum lease and service credit commitments, including renewal periods, are approximately $303 million for the 12-month period ending September 30, 2024, $602 million in total for both of the 12-month periods ending September 30, 2025 and 2026, $666 million in total for both of the 12-month periods ending September 30, 2027 and 2028, and $4.4 billion in total thereafter.

On August 8, 2022, we entered into License Purchase Agreements to acquire spectrum in the 600 MHz band from Channel 51 License Co LLC and LB License Co, LLC in exchange for total cash consideration of $3.5 billion. The licenses are currently being utilized by us through exclusive leasing arrangements with the Sellers. On March 30, 2023, we and the Sellers entered into Amended and Restated License Purchase Agreements pursuant to which we and the Sellers agreed to separate the transaction into two tranches of licenses, with the closings on the acquisitions of certain licenses in Chicago, Dallas and New Orleans being deferred in order to potentially expedite the regulatory approval process for the remainder of the licenses. Subsequently, on August 25, 2023, we and the Sellers entered into Amendments No. 1 to the Amended and Restated License Purchase Agreements, which deferred the closings of certain additional licenses in Chicago and Dallas into the second closing

24

tranche. Together, the licenses with closings deferred into the second closing tranche represent approximately $1.1 billion of the aggregate $3.5 billion cash consideration. The agreements remain subject to regulatory approval and are excluded from our reported purchase commitments above. See Note 5 – Spectrum License Transactions for additional details.

On September 12, 2023, we entered into a License Purchase Agreement with Comcast pursuant to which we will acquire spectrum in the 600 MHz band from Comcast in exchange for total cash consideration of between $1.2 billion and $3.3 billion, subject to an application for FCC approval. The licenses are subject to an exclusive leasing arrangement between us and Comcast entered into contemporaneously with the License Purchase Agreement. The agreement remains subject to regulatory approval and is excluded from our reported purchase commitments above. See Note 5 – Spectrum License Transactions for additional details.

Merger Commitments

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

Contingencies and Litigation

Litigation and Regulatory Matters

We are involved in various lawsuits and disputes, claims, government agency investigations and enforcement actions, and other proceedings (“Litigation and Regulatory Matters”) that arise in the ordinary course of business, which include claims of patent infringement (most of which are asserted by non-practicing entities primarily seeking monetary damages), class actions, and proceedings to enforce FCC or other government agency rules and regulations. Those Litigation and Regulatory Matters are at various stages, and some of them may proceed to trial, arbitration, hearing, or other adjudication that could result in fines, penalties, or awards of monetary or injunctive relief in the coming 12 months if they are not otherwise resolved. We have established an accrual with respect to certain of these matters, where appropriate. The accruals are reflected on our condensed consolidated financial statements, but they are not considered to be, individually or in the aggregate, material. An accrual is established when we believe it is both probable that a loss has been incurred and an amount can be reasonably estimated. For other matters, where we have not determined that a loss is probable or because the amount of loss cannot be reasonably estimated, we have not recorded an accrual due to various factors typical in contested proceedings, including, but not limited to, uncertainty concerning legal theories and their resolution by courts or regulators, uncertain damage theories and demands, and a less than fully developed factual record. For Litigation and Regulatory Matters that may result in a contingent gain, we recognize such gains on our 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 or other matters that we are or may become involved in could have a material adverse impact on results of operations or cash flows for a particular period. This assessment is based on our current understanding of relevant facts and circumstances. As such, our view of these matters is subject to inherent uncertainties and may change in the future.

On February 28, 2020, we received a Notice of Apparent Liability for Forfeiture and Admonishment from the FCC, which proposed a penalty against us for allegedly violating section 222 of the Communications Act and the FCC’s regulations governing the privacy of customer information. In the first quarter of 2020, we recorded an accrual for an estimated payment amount. We maintained the accrual as of September 30, 2023, and that accrual was included in Accounts payable and accrued liabilities on 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.

25

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

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

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

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

As a result of the August 2021 cyberattack, we have become subject to numerous lawsuits, including mass arbitration claims and multiple class action lawsuits that have been filed in numerous jurisdictions seeking, among other things, unspecified monetary damages, costs and attorneys’ fees arising out of the August 2021 cyberattack. In December 2021, the Judicial Panel on Multidistrict Litigation consolidated the federal class action lawsuits in the U.S. District Court for the Western District of Missouri under the caption In re: T-Mobile Customer Data Security Breach Litigation, Case No. 21-md-3019-BCW. On July 22, 2022, we entered into an agreement to settle the lawsuit. On June 29, 2023, the Court issued an order granting final approval of the settlement, which is subject to potential appeals. Under the terms of the settlement, we would pay an aggregate of $350 million to fund claims submitted by class members, the legal fees of plaintiffs’ counsel and the costs of administering the settlement. We would also commit to an aggregate incremental spend of $150 million for data security and related technology in 2022 and 2023. We previously paid $35 million for claims administration purposes. On July 31, 2023, a class member filed an appeal to the final approval order challenging the Court’s award of attorneys’ fees to class counsel. We expect the remaining portion of the $350 million settlement payment to fund claims to be made once that appeal is resolved. We anticipate that, upon exhaustion of any appeals, the settlement will provide a full release of all claims arising out of the August 2021 cyberattack by class members who do not opt out, against all defendants, including us, our subsidiaries and affiliates, and our directors and officers. The settlement contains no admission of liability, wrongdoing or responsibility by any of the defendants. We have the right to terminate the settlement agreement under certain conditions.

We anticipate that this settlement of the class action, along with other settlements of separate consumer claims that have been previously completed or are currently pending, will resolve substantially all of the claims brought to date by our current, former and prospective customers who were impacted by the 2021 cyberattack. In connection with the proposed class action settlement and the separate settlements, we recorded a total pre-tax charge of approximately $400 million in the second quarter of 2022. During each of the nine months ended September 30, 2023 and 2022, we recognized $50 million in reimbursements from insurance carriers for costs incurred related to the August 2021 cyberattack, which is included as a reduction to Selling, general and administrative expenses on our Condensed Consolidated Statements of Comprehensive Income. The ultimate resolution of the class action depends on the number of plaintiffs who opt-out of the proposed settlement and whether the proposed settlement will be appealed.

26

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

We have also received inquiries from various government agencies, law enforcement and other governmental authorities related to the August 2021 cyberattack which could result in substantial fines or penalties. We are cooperating fully with these agencies and regulators and working with them to resolve these matters. While we hope to resolve them in the near term, we cannot predict the timing or outcome of any of these matters, or whether we may be subject to further regulatory inquiries, investigations, or enforcement actions.

In light of the inherent uncertainties involved in such matters and based on the information currently available to us, in addition to the previously recorded pre-tax charge of approximately $400 million noted above, we believe it is reasonably possible that we could incur additional losses associated with these proceedings and inquiries, and we will continue to evaluate information as it becomes known and will record an estimate for losses at the time or times when it is both probable that a loss has been incurred and the amount of the loss is reasonably estimable. Ongoing legal and other costs related to these proceedings and inquiries, as well as any potential future actions, may be substantial, and losses associated with any adverse judgments, settlements, penalties or other resolutions of such proceedings and inquiries could be material to our business, reputation, financial condition, cash flows and operating results.

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

On January 5, 2023, we identified that a bad actor was obtaining data through a single Application Programming Interface (“API”) without authorization. Based on our investigation, the impacted API is only able to provide a limited set of customer account data, including name, billing address, email, phone number, date of birth, T-Mobile account number and information such as the number of lines on the account and plan features. The result from our investigation indicates that the bad actor(s) obtained data from this API for approximately 37 million current postpaid and prepaid customer accounts, though many of these accounts did not include the full data set. We believe that the bad actor first retrieved data through the impacted API starting on or around November 25, 2022. We have notified individuals whose information was impacted consistent with state and federal requirements.

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

Note 14 – Restructuring Costs

Merger Restructuring Initiatives

Upon close of the Merger in April 2020, we began implementing restructuring initiatives to realize cost efficiencies and reduce redundancies. The major activities associated with the Merger restructuring initiatives to date include contract termination costs associated with the rationalization of retail stores, distribution channels, duplicative network and backhaul services and other agreements, severance costs associated with the integration of redundant processes and functions and the decommissioning of certain small cell sites and distributed antenna systems to achieve Merger synergies in network costs.

27

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

(in millions)	Three Months Ended September 30, 2023		Nine Months Ended September 30, 2023		Incurred to Date

(1)    Non-cash items primarily consist of the write-off of assets within Network decommissioning.

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

We expect to incur substantially all remaining costs associated with our Merger restructuring activities by the end of this year, with the related cash outflows extending beyond 2023.

2023 Workforce Reduction

In August 2023, we began implementing an initiative to reduce the size of our workforce by approximately 5,000 positions, just under 7% of our total employee base, primarily in corporate and back-office functions, and some technology roles. We recorded a pre-tax charge of $471 million during the three months ended September 30, 2023, related to the workforce reduction, which is included in Costs of services and Selling, general and administrative expenses on our Condensed Consolidated Statements of Comprehensive Income.

The changes in the liabilities associated with our workforce reduction initiative, including expenses incurred and cash payments, are as follows:

(in millions)	December 31, 2022		Expenses Incurred		Cash Payments		Other (1)		September 30, 2023
Severance costs	$	—	$	471	$	(18)	$	14	$	467

(1)    Other primarily consists of previously expensed vacation accruals expected to be paid out as a component of severance.

The liabilities accrued in connection with our workforce reduction activities are presented in Accounts payable and accrued liabilities on our Condensed Consolidated Balance Sheets.

Substantially all costs associated with our workforce reduction activities were recorded during the three months ended September 30, 2023, with substantially all related cash outflows extending through mid-2024.

Sprint Merger, Network Integration and Decommissioning 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, migrate customers to the T-Mobile network and billing systems and the impact of legal matters assumed as part of the Merger;

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

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

Restructuring costs are disclosed in Note 14 – Restructuring Costs of the Notes to the Condensed Consolidated Financial Statements. Merger-related costs have been excluded from our calculations of Adjusted EBITDA and Core Adjusted EBITDA, which are non-GAAP financial measures, as we do not consider these costs to be reflective of our ongoing operating performance. See “Adjusted EBITDA and Core Adjusted EBITDA” in the “Performance Measures” section of this MD&A. Net cash payments for Merger-related costs, including payments related to our restructuring plan, are included in Net cash provided by operating activities on our Condensed Consolidated Statements of Cash Flows.

Merger-related costs are presented below:

(in millions)	Three Months Ended September 30,				Change				Nine Months Ended September 30,				Change
	2023		2022		$		%		2023		2022		$		%
Merger-related costs
Cost of services, exclusive of depreciation and amortization	$	120	$	812	$	(692)	(85)	%	$	506	$	2,380	$	(1,874)	(79)	%
Cost of equipment sales, exclusive of depreciation and amortization	(3)		258		(261)		(101)	%	(12)		1,468		(1,480)		(101)	%
Selling, general and administrative	35		226		(191)		(85)	%	292		529		(237)		(45)	%
Total Merger-related costs	$	152	$	1,296	$	(1,144)	(88)	%	$	786	$	4,377	$	(3,591)	(82)	%
Net cash payments for Merger-related costs	$	345	$	942	$	(597)	(63)	%	$	1,557	$	2,742	$	(1,185)	(43)	%

We expect to incur substantially all of the remaining projected Merger-related costs of approximately $200 million, excluding capital expenditures, by the end of 2023, with the cash expenditure for the Merger-related costs extending beyond 2023.

Anticipated Merger Synergies

As a result of our ongoing restructuring and integration activities, we have realized Merger synergies by eliminating redundancies within our combined network as well as other business processes and operations. For full-year 2023, we expect Merger synergies from Selling, general and administrative expense reductions of approximately $2.7 billion, Cost of service expense reductions of approximately $3.2 billion and avoided network expenses of approximately $1.6 billion.

2023 Workforce Reduction

In August 2023, we began implementing an initiative to reduce the size of our workforce by approximately 5,000 positions, just under 7% of our total employee base, primarily in corporate and back-office functions, and some technology roles. We expect a decrease in operating expenses in 2024 driven by reduced personnel costs.

For more information regarding our restructuring activities, see Note 14 – Restructuring Costs of the Notes to the Condensed Consolidated Financial Statements.

Wireline

On September 6, 2022, we entered into the Wireline Sale Agreement to sell the Wireline Business for a total purchase price of $1 and the payments totaling $700 million under the IP transit services agreement. On May 1, 2023, pursuant to the Wireline Sale Agreement, upon the terms and subject to the conditions thereof, we completed the Wireline Transaction.

32

For more information regarding the Wireline Sale Agreement, see Note 11 – Wireline of the Notes to the Condensed Consolidated Financial Statements.

Acquisition of Ka’ena Corporation

On March 9, 2023, we entered into a Merger and Unit Purchase Agreement for the acquisition of 100% of the outstanding equity of Ka’ena Corporation and its subsidiaries including, among others, Mint Mobile LLC, for a maximum purchase price of $1.35 billion to be paid out 39% in cash and 61% in shares of T-Mobile common stock. The purchase price is variable dependent upon specified performance indicators of Ka’ena Corporation during certain periods before and after closing and consists of an upfront payment at closing of the transaction, subject to certain agreed-upon adjustments, and a variable earnout payable 24 months after closing of the transaction. Our estimate of the upfront payment is subject to Ka’ena Corporation’s underlying business performance and the timing of transaction close, and has been updated to $1.2 billion, before working capital adjustments. The acquisition is subject to certain customary closing conditions, including certain regulatory approvals, and is expected to close by the end of the first quarter of 2024.

Ka’ena Corporation is currently one of our wholesale partners, offering wireless telecommunications services to customers leveraging our network. Upon closing of the transactions, we expect to recognize customers of Ka’ena Corporation as prepaid customers and expect to see an increase in Prepaid revenues, partially offset by a decrease in Wholesale revenues.

Recent Cyberattacks

In August 2021, we were subject to a criminal cyberattack involving unauthorized access to T-Mobile’s systems. As a result of the attack, we are subject to numerous arbitration demands and lawsuits, including class action lawsuits, and regulatory inquiries as described in Note 13 – Commitments and Contingencies of the Notes to the Condensed Consolidated Financial Statements.

During the nine months ended September 30, 2023, we recognized $50 million in reimbursements from insurance carriers for costs incurred related to the August 2021 cyberattack. We are pursuing additional reimbursements from insurance carriers for costs incurred related to the August 2021 cyberattack.

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

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

In response to the recent cyberattacks and increasing cybersecurity threats, we have significantly increased our focus on enhancing our cybersecurity practices with a substantial multi-year investment. In the second quarter of 2023, we have hired new security leadership, and implemented significant technology improvements to our cybersecurity controls. Those improvements include additional authentication measures and internal systems limitations and restrictions. In addition, we have enhanced our cybersecurity awareness program, including rolling out new training for all employees. While we have made progress to date, we plan to continue to make substantial investments to strengthen our cybersecurity program in future periods.

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.

High Speed Internet customers included in Postpaid other customers were 3,807,000 and 1,960,000 as of September 30, 2023 and 2022, respectively. High Speed Internet customers included in Prepaid customers were 428,000 and 162,000 as of September 30, 2023 and 2022, respectively.

Net Customer Additions

The following table sets forth the number of net customer additions:

	Three Months Ended September 30,		Change			Nine Months Ended September 30,		Change

Total net customer additions decreased 427,000, or 25%, for the three months ended and decreased 605,000, or 12%, for the nine months ended September 30, 2023.

The decrease for the three months ended September 30, 2023, was primarily from:

•Lower postpaid other net customer additions, primarily due to deactivations from mobile internet devices in the educational sector that were originally activated during the COVID-19 pandemic (“Pandemic”) and no longer needed; and

•Lower prepaid net customer additions, primarily due to continued moderation of industry growth and fewer High Speed Internet net additions, partially offset by lower churn.

•Postpaid phone net customer additions were relatively flat, primarily due to increased deactivations from a growing customer base despite slightly lower churn, offset by higher gross additions.

•High Speed Internet net customer additions included in postpaid other net customer additions were 505,000 and 488,000 for the three months ended September 30, 2023 and 2022, respectively. High Speed Internet net customer additions included in prepaid net customer additions were 52,000 and 90,000 for the three months ended September 30, 2023 and 2022, respectively.

The decrease for the nine months ended September 30, 2023, was primarily from:

•Lower postpaid other net customer additions, primarily due to

•Deactivations from mobile internet devices in the educational sector that were originally activated during the Pandemic and no longer needed; and

•Lower net additions from other connected devices; partially offset by

•Higher High Speed Internet net customer additions, primarily due to continued growth in gross additions driven by increasing customer demand, partially offset by increased deactivations from a growing customer base; and

•Lower prepaid net customer additions, primarily due to continued moderation of industry growth and continued industry migration of prepaid to postpaid, partially offset by growth in High Speed Internet; and

•Slightly lower postpaid phone net customer additions, primarily due to increased deactivations from a growing customer base despite slightly lower churn, mostly offset by higher gross additions.

•High Speed Internet net customer additions included in postpaid other net customer additions were 1,397,000 and 1,314,000 for the nine months ended September 30, 2023 and 2022, respectively. High Speed Internet net customer additions included in prepaid net customer additions were 192,000 and 162,000 for the nine months ended September 30, 2023 and 2022, respectively.

Churn

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

The following table sets forth the churn:

	Three Months Ended September 30,				Change	Nine Months Ended September 30,				Change
	2023		2022			2023		2022
Postpaid phone churn	0.87	%	0.88	%	-1 bps	0.84	%	0.87	%	-3 bps
Prepaid churn	2.81	%	2.88	%	-7 bps	2.73	%	2.71	%	2 bps

Postpaid phone churn decreased 1 basis point for the three months ended and decreased 3 basis points for the nine months ended September 30, 2023, primarily from improved customer retention driven by a differentiated value proposition and network experience.

Prepaid churn decreased 7 basis points for the three months ended and increased 2 basis points for the nine months ended September 30, 2023.

The decrease for the three months ended September 30, 2023, was primarily from improved customer retention.

The increase for the nine months ended September 30, 2023, was primarily from continued industry migration of prepaid to postpaid.

Postpaid Average Revenue Per Account

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

The following table sets forth our operating measure ARPA:

(in dollars)	Three Months Ended September 30,				Change				Nine Months Ended September 30,				Change
	2023		2022		$		%		2023		2022		$		%
Postpaid ARPA	$	139.83	$	137.49	$	2.34	2	%	$	138.94	$	137.32	$	1.62	1	%

Postpaid ARPA increased $2.34, or 2%, for the three months ended and increased $1.62, or 1%, for the nine months ended September 30, 2023.

The increase for the three months ended September 30, 2023, was primarily from:

•An increase in customers per account, including growth in business and continued adoption of High Speed Internet; and

•Higher premium services, primarily high-end rate plans, net of contra-revenue for content included in such plans and discounts for specific affinity groups, such as 55+, Military and First Responder; partially offset by

•Increased promotional activity; and

•An increase in High Speed Internet only accounts.

43

The slight increase for the nine months ended September 30, 2023, was primarily from:

•Higher premium services, primarily high-end rate plans, net of contra-revenue for content included in such plans and discounts for specific affinity groups, such as 55+, Military and First Responder; and

•An increase in customers per account, including growth in business and continued adoption of High Speed Internet; partially offset by

•Increased promotional activity; and

•An increase in High Speed Internet only accounts.

Average Revenue Per User

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

The following table sets forth our operating measure ARPU:

(in dollars)	Three Months Ended September 30,				Change				Nine Months Ended September 30,				Change
	2023		2022		$		%		2023		2022		$		%
Postpaid phone ARPU	$	48.93	$	48.89	$	0.04	—	%	$	48.80	$	48.75	$	0.05	—	%
Prepaid ARPU	38.18		38.86		(0.68)		(2)	%	38.05		38.92		(0.87)		(2)	%

Postpaid Phone ARPU

Postpaid phone ARPU was relatively flat for the three and nine months ended September 30, 2023, primarily from:

•Higher premium services, primarily high-end rate plans, net of contra-revenue for content included in such plans and discounts for specific affinity groups, such as 55+, Military and First Responders; offset by

•Increased promotional activity; and

•Growth in business with lower ARPU given larger account sizes.

Prepaid ARPU

Prepaid ARPU decreased $0.68, or 2%, for the three months ended and decreased $0.87, or 2%, for the nine months ended September 30, 2023, primarily from dilution from promotional rate plan mix.

Adjusted EBITDA and Core Adjusted EBITDA

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

Adjusted EBITDA, Adjusted EBITDA margin, Core Adjusted EBITDA and Core Adjusted EBITDA margin are non-GAAP financial measures utilized by our management to monitor the financial performance of our operations. We historically used Adjusted EBITDA and we currently use Core Adjusted EBITDA internally as a measure to evaluate and compensate our personnel and management for their performance. We use Adjusted EBITDA and Core Adjusted EBITDA as benchmarks to evaluate our operating performance in comparison to our competitors. Management believes analysts and investors use Adjusted EBITDA and Core Adjusted EBITDA as supplemental measures to evaluate overall operating performance and to facilitate comparisons with other wireless communications services companies because they are indicative of our ongoing operating performance and trends by excluding the impact of interest expense from financing, non-cash depreciation and amortization from capital investments, stock-based compensation, Merger-related costs, including network decommissioning

44

costs, impairment expense, gain on disposal groups held for sale and certain legal-related recoveries and expenses, as well as other special income and expenses, including the August 2023 workforce reduction, which are not reflective of our core business activities. Management believes analysts and investors use Core Adjusted EBITDA because it normalizes for the transition in the Company’s device financing strategy, by excluding the impact of device lease revenues from Adjusted EBITDA, to align with the exclusion of the related depreciation expense on leased devices from Adjusted EBITDA. Adjusted EBITDA, Adjusted EBITDA margin, Core Adjusted EBITDA and Core Adjusted EBITDA margin have limitations as analytical tools and should not be considered in isolation or as substitutes for income from operations, net income or any other measure of financial performance reported in accordance with GAAP.

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

NM - Not meaningful

Core Adjusted EBITDA increased $819 million, or 12%, for the three months ended and increased $2.1 billion, or 11%, for the nine months ended September 30, 2023. The components comprising Core Adjusted EBITDA are discussed further above.

45

The increase for the three months ended September 30, 2023, was primarily from:

•Higher Total service revenues;

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

•Lower Cost of services, excluding Merger-related costs and other special items, such as severance and related costs associated with the August 2023 workforce reduction; partially offset by

•Lower Equipment revenues, excluding lease revenues.

The increase for the nine months ended September 30, 2023, was primarily from:

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

•Higher Total service revenues; and

•Lower Cost of services, excluding Merger-related costs and other special items, such as severance and related costs associated with the August 2023 workforce reduction; partially offset by

•Lower Equipment revenues, excluding lease revenues.

Adjusted EBITDA increased $561 million, or 8%, for the three months ended and increased $1.2 billion, or 6%, for the nine months ended September 30, 2023, primarily due to the fluctuations in Core Adjusted EBITDA, discussed above, partially offset by lower lease revenues, which decreased $258 million for the three months ended and decreased $915 million for the nine months ended September 30, 2023.

Liquidity and Capital Resources

Our principal sources of liquidity are our cash and cash equivalents and cash generated from operations, proceeds from issuance of debt, financing leases, the sale of certain receivables, the Revolving Credit Facility (as defined below) and, beginning in July 2023, an unsecured short-term commercial paper program. Further, the incurrence of additional indebtedness may inhibit our ability to incur new debt in the future to finance our business strategy under the terms governing our existing and future indebtedness.

Cash Flows

The following is a condensed schedule of our cash flows:

	Three Months Ended September 30,				Change				Nine Months Ended September 30,				Change

The increase for the three months ended September 30, 2023, was primarily from:

•A $1.7 billion increase in Net income, adjusted for non-cash income and expense; partially offset by

•An $846 million increase in net cash outflows from changes in working capital, primarily due to higher use of cash from Other current and long-term liabilities, Inventory, Operating lease right-of-use assets and Accounts payable and accrued liabilities, partially offset by lower use of cash from Equipment installment plan receivables, Other current and long-term assets and Accounts receivable.

•Net cash provided by operating activities includes the impact of $345 million and $942 million in net payments for Merger-related costs for the three months ended September 30, 2023 and 2022, respectively.

46

The increase for the nine months ended September 30, 2023, was primarily from:

•A $5.1 billion increase in Net income, adjusted for non-cash income and expense; partially offset by

•A $3.8 billion increase in net cash outflows from changes in working capital, primarily due to higher use of cash from Accounts payable and accrued liabilities, Other current and long-term liabilities, Operating lease right-of-use assets and Short- and long-term operating lease liabilities, partially offset by lower use of cash from Equipment installment plan receivables and Other current and long-term assets.

•Net cash provided by operating activities includes the impact of $1.6 billion and $2.7 billion in net payments for Merger-related costs for the nine months ended September 30, 2023 and 2022, respectively.

Investing Activities

Net cash used in investing activities decreased $1.2 billion, or 45%, for the three months ended and decreased $5.6 billion, or 55%, for the nine months ended September 30, 2023.

The use of cash for the three months ended September 30, 2023, was primarily from:

•$2.4 billion in Purchases of property and equipment, including capitalized interest, from the accelerated build-out of our nationwide 5G network; partially offset by

•$1.1 billion in Proceeds related to beneficial interests in securitization transactions.

The use of cash for the nine months ended September 30, 2023, was primarily from:

•$8.2 billion in Purchases of property and equipment, including capitalized interest, from the accelerated build-out of our nationwide 5G network; partially offset by

•$3.8 billion in Proceeds related to beneficial interests in securitization transactions.

Financing Activities

Net cash used in financing activities increased $7.4 billion, or 386%, for the three months ended and increased $6.6 billion, or 339%, for the nine months ended September 30, 2023.

The use of cash for the three months ended September 30, 2023, was primarily from:

Cash and Cash Equivalents

As of September 30, 2023, our Cash and cash equivalents were $5.0 billion compared to $4.5 billion at December 31, 2022.

47

Adjusted Free Cash Flow

Adjusted Free Cash Flow represents Net cash provided by operating activities less cash payments for Purchases of property and equipment, plus Proceeds from sales of tower sites and Proceeds related to beneficial interests in securitization transactions and less Cash payments for debt prepayment or debt extinguishment costs. Adjusted Free Cash Flow is a non-GAAP financial measure utilized by management, investors and analysts of our financial information to evaluate cash available to pay debt, repurchase shares, pay dividends and provide further investment in the business. Starting in the first quarter of 2023, we renamed Free Cash Flow to Adjusted Free Cash Flow. This change in name did not result in any change to the definition or calculation of this non-GAAP financial measure. Adjusted Free Cash Flow margin is calculated as Adjusted Free Cash Flow divided by Service Revenues. Adjusted Free Cash Flow margin is utilized by management, investors, and analysts to evaluate the company’s ability to convert service revenue efficiently into cash available to pay debt, repurchase shares, pay dividends and provide further investment in the business.

The table below provides a reconciliation of Adjusted Free Cash Flow to Net cash provided by operating activities, which we consider to be the most directly comparable GAAP financial measure:

	Three Months Ended September 30,						Change				Nine Months Ended September 30,						Change

NM - Not Meaningful

Adjusted Free Cash Flow increased $1.9 billion, or 94%, for the three months ended and increased $3.8 billion, or 70%, for the nine months ended September 30, 2023.

The increase for the three months ended September 30, 2023, was primarily impacted by the following:

•Lower Cash purchases of property and equipment, including capitalized interest, driven by increased capital efficiencies from accelerated investments in our nationwide 5G network in 2022; and

•Higher Net cash provided by operating activities, as described above; partially offset by

•Lower Proceeds related to beneficial interests in securitization transactions, which were offset in Net cash provided by operating activities.

•Adjusted Free Cash Flow includes the impact of $345 million and $942 million in net payments for Merger-related costs for the three months ended September 30, 2023 and 2022, respectively.

The increase for the nine months ended September 30, 2023, was primarily impacted by the following:

•Lower Cash purchases of property and equipment, including capitalized interest, driven by increased capital efficiencies from accelerated investments in our nationwide 5G network in 2022;

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

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

•Adjusted Free Cash Flow includes the impact of $1.6 billion and $2.7 billion in net payments for Merger-related costs for the nine months ended September 30, 2023 and 2022, respectively.

During the nine months ended September 30, 2023 and 2022, there were no significant net cash proceeds from securitization.

Borrowing Capacity

We maintain a revolving credit facility (the “Revolving Credit Facility”) with an aggregate commitment amount of $7.5 billion. As of September 30, 2023, there was no outstanding balance under the Revolving Credit Facility.

On July 25, 2023, we established an unsecured short-term commercial paper program with the ability to borrow up to $2.0 billion from time to time. This program will supplement our other available external financing arrangements and proceeds are expected to be used for general corporate purposes. As of September 30, 2023, there was no outstanding balance under this program.

Debt Financing

As of September 30, 2023, our total debt and financing lease liabilities were $77.9 billion, excluding our tower obligations, of which $71.9 billion was classified as long-term debt and $1.3 billion was classified as long-term financing lease liabilities.

During the nine months ended September 30, 2023, we issued long-term debt for net proceeds of $8.4 billion and redeemed and repaid short-term debt with an aggregate principal amount of $4.8 billion.

For more information regarding our debt financing transactions, see Note 7 - Debt of the Notes to the Condensed Consolidated Financial Statements.

License Purchase Agreements

On August 8, 2022, we entered into License Purchase Agreements to acquire spectrum in the 600 MHz band from Channel 51 License Co LLC and LB License Co, LLC in exchange for total cash consideration of $3.5 billion. On March 30, 2023, we and the Sellers entered into Amended and Restated License Purchase Agreements pursuant to which we and the Sellers agreed to bifurcate the transaction into two tranches of licenses, with the closings on the acquisitions of certain licenses in Chicago, Dallas and New Orleans being deferred in order to potentially expedite the regulatory approval process for the remainder of the licenses. Subsequently, on August 25, 2023, we and the Sellers entered into Amendments No. 1 to the Amended and Restated License Purchase Agreements whereby we deferred the closings of certain additional licenses in Chicago and Dallas into the second closing tranche. Together, the licenses with closings deferred into the second closing tranche represent approximately $1.1 billion of the aggregate $3.5 billion cash consideration. We anticipate that the first closing will occur no earlier than the first half of 2024 and that the second closing (on the deferred licenses) will occur in late 2024 or early 2025.

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

On September 12, 2023, we entered into a License Purchase Agreement with Comcast pursuant to which we will acquire spectrum in the 600 MHz band from Comcast in exchange for total cash consideration of between $1.2 billion and $3.3 billion, subject to an application for FCC approval. We anticipate the closing will occur in the first half of 2028.

For more information regarding our License Purchase Agreements, see Note 5 – Spectrum License Transactions of the Notes to the Condensed Consolidated Financial Statements.

Acquisition of Ka’ena Corporation

On March 9, 2023, we entered into a Merger and Unit Purchase Agreement for the acquisition of 100% of the outstanding equity of Ka’ena Corporation and its subsidiaries including, among others, Mint Mobile LLC for a maximum purchase price of $1.35 billion to be paid out 39% in cash and 61% in shares of T-Mobile common stock. The purchase price is variable dependent upon specified performance indicators of Ka’ena Corporation during certain periods before and after closing and consists of an upfront payment at closing of the transaction, subject to certain agreed-upon adjustments, and a variable earnout payable 24 months after closing of the transaction. Our estimate of the upfront payment is subject to Ka’ena Corporation’s underlying business performance and the timing of transaction close, and has been updated to $1.2 billion, before working capital adjustments. The acquisition is subject to certain customary closing conditions, including certain regulatory approvals, and is expected to close by the end of the first quarter of 2024.

Off-Balance Sheet Arrangements

We have arrangements, as amended from time to time, to sell certain EIP accounts receivable and service accounts receivable on a revolving basis as a source of liquidity. As of September 30, 2023, we derecognized net receivables of $2.4 billion upon sale through these arrangements. 

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

Future Sources and Uses of Liquidity

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

We determine future liquidity requirements for operations, capital expenditures, share repurchases and dividend payments based in large part upon projected financial and operating performance, and opportunities to acquire additional spectrum or repurchase shares. We regularly review and update these projections for changes in current and projected financial and operating results, general economic conditions, the competitive landscape and other factors. We have incurred, and will incur, substantial expenses to comply with the Government Commitments, and we are also expected to incur substantially all of the remaining projected Merger-related costs of approximately $200 million, excluding capital expenditures, by the end of 2023, with the cash expenditure for the Merger-related costs extending beyond 2023. 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. There are a number of additional risks and uncertainties that could cause our financial and operating results and capital requirements to differ materially from our projections, which could cause future liquidity to differ materially from our assessment.

The indentures, supplemental indentures and credit agreements governing our long-term debt to affiliates and third parties, excluding financing leases, contain covenants that, among other things, limit the ability of the Issuers or borrowers and the Guarantor Subsidiaries to incur more debt, create liens or other encumbrances, and merge, consolidate or sell, or otherwise dispose of, substantially all of their assets. We were in compliance with all restrictive debt covenants as of September 30, 2023.

Financing Lease Facilities

We have uncommitted financing lease facilities with certain third parties that provide us with the ability to enter into financing leases for network equipment and services. As of September 30, 2023, we have entered into $8.5 billion of financing leases under these financing lease facilities, of which $388 million and $940 million was executed during the three and nine months ended September 30, 2023, respectively. We expect to enter into up to a total of $1.2 billion in financing lease commitments during the year ending December 31, 2023.

Capital Expenditures

Our liquidity requirements have been driven primarily by capital expenditures for spectrum licenses, the construction, expansion and upgrading of our network infrastructure and the integration of the networks, spectrum, technology, personnel and customer base of T-Mobile and Sprint. Property and equipment capital expenditures primarily relate to the integration of our network and spectrum licenses, including acquired Sprint PCS and 2.5 GHz spectrum licenses, as we build out our nationwide 5G network. We expect a reduction in capital expenditures related to these efforts in 2023 compared to 2022. Future capital expenditure requirements will include the deployment of our recently acquired C-band and 3.45 GHz spectrum licenses.

For more information regarding our spectrum licenses, see Note 5 – Spectrum License Transactions of the Notes to the Condensed Consolidated Financial Statements.

Stockholder Returns

On September 8, 2022, our Board of Directors authorized our 2022 Stock Repurchase Program for up to $14.0 billion of our common stock through September 30, 2023. During the three and nine months ended September 30, 2023, we repurchased shares of our common stock for a total purchase price of $2.7 billion and $11.0 billion, respectively, all of which were purchased under the 2022 Stock Repurchase Program.

On September 6, 2023, our Board of Directors authorized our 2023-2024 Stockholder Return Program for up to $19.0 billion that will run through December 31, 2024. The 2023-2024 Stockholder Return Program is expected to consist of additional repurchases of shares of our common stock and the payment of cash dividends.

On September 25, 2023, our Board of Directors declared a cash dividend of $0.65 per share on our issued and outstanding shares of common stock, which will be paid in the fourth quarter of 2023. As of September 30, 2023, $745 million for dividends payable is presented within Other current liabilities on our Condensed Consolidated Balance Sheets. We intend to declare and pay approximately $3.0 billion in total additional dividends in 2024, with payments occurring each quarter during the year. The dividend amount paid per share is expected to grow by around 10% annually with the first increase expected in the fourth quarter of 2024; however, the declaration and payment of future dividends is subject to the discretion of our Board of Directors and will depend on financial and legal requirements and other considerations. The amount available under the 2023-2024 Stockholder Return Program for share repurchases will be reduced by the amount of any cash dividends declared by us.

Subsequent to September 30, 2023, from October 1, 2023, through October 20, 2023, we repurchased 5,515,568 shares of our common stock for a total purchase price of $771 million. As of October 20, 2023, we had up to $17.5 billion remaining under the 2023-2024 Stockholder Return Program.

For additional information regarding the 2022 Stock Repurchase Program and the 2023-2024 Stockholder Return Program, see Note 10 – Stockholder Return Programs of the Notes to the Condensed Consolidated Financial Statements.

Related Party Transactions

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

As of October 20, 2023, DT held, directly or indirectly, approximately 52.3% of the outstanding T-Mobile common stock, with the remaining approximately 47.7% of the outstanding T-Mobile common stock held by SoftBank and other stockholders. As a result of the Proxy, Lock-Up and ROFR Agreement, dated April 1, 2020, by and between DT and SoftBank and the Proxy, Lock-Up and ROFR Agreement, dated June 22, 2020, by and among DT, Claure Mobile LLC, and Marcelo Claure, DT has voting control, as of October 20, 2023, over approximately 56.2% of the outstanding T-Mobile common stock.

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

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

As of the date of this report, we are not aware of any activity, transaction or dealing by us or any of our affiliates for the three months ended September 30, 2023, that requires disclosure in this report under Section 13(r) of the Exchange Act, except as set forth below with respect to affiliates that we do not control and that are our affiliates solely due to their common control with either DT or SoftBank. We have relied upon DT and SoftBank for information regarding their respective activities, transactions and dealings.

DT, through certain of its non-U.S. subsidiaries, is party to roaming and interconnect agreements with the following mobile and fixed line telecommunication providers in Iran, some of which are or may be government-controlled entities: Telecommunication Kish Company, Mobile Telecommunication Company of Iran, and Telecommunication Infrastructure Company of Iran. In addition, during the three months ended September 30, 2023, DT, through certain of its non-U.S. subsidiaries, provided basic telecommunications services to five customers in Germany identified on the Specially Designated

51

Nationals and Blocked Persons List maintained by the U.S. Department of Treasury’s Office of Foreign Assets Control: Bank Melli, Europäisch-Iranische Handelsbank, CPG Engineering & Commercial Services GmbH, Golgohar Trade and Technology GmbH and International Trade and Industrial Technology ITRITEC GmbH. With respect to the first four of these customers, the services have been terminated or are in the process of being terminated. DT is currently evaluating the relationship its non-U.S. subsidiary has with International Trade and Technology ITRITEC GmbH. For the three months ended September 30, 2023, gross revenues of all DT affiliates generated by roaming and interconnection traffic and telecommunications services with the Iranian parties identified herein were less than $0.1 million, and the estimated net profits were less than $0.1 million.

In addition, DT, through certain of its non-U.S. subsidiaries that operate a fixed-line network in their respective European home countries (in particular Germany), provides telecommunications services in the ordinary course of business to the Embassy of Iran in those European countries. Gross revenues and net profits recorded from these activities for the three months ended September 30, 2023, were less than $0.1 million. We understand that DT intends to continue these activities.

Separately, SoftBank, through one of its non-U.S. subsidiaries, provides roaming services in Iran through Irancell Telecommunications Services Company. During the three months ended September 30, 2023, SoftBank had no gross revenues from such services and no net profit was generated. We understand that the SoftBank subsidiary intends to continue such services. This subsidiary also provides telecommunications services in the ordinary course of business to accounts affiliated with the Embassy of Iran in Japan. During the three months ended September 30, 2023, SoftBank estimates that gross revenues and net profit generated by such services were both under $0.1 million. We understand that the SoftBank subsidiary is obligated under contract and intends to continue such services.

In addition, SoftBank, through one of its non-U.S. indirect subsidiaries, provides office supplies to the Embassy of Iran in Japan. SoftBank estimates that gross revenue and net profit generated by such services during the three months ended September 30, 2023, were both under $0.1 million. We understand that the SoftBank subsidiary intends to continue such activities.

Item 1A. Risk Factors

Other than the updated risk factors below, there have been no material changes in our risk factors as previously disclosed in Part I, Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2022.

Risks Related to Our Business

We have experienced criminal cyberattacks and could in the future be further harmed by disruption, data loss or other security breaches, whether directly or indirectly through third parties whose products and services we rely on in operating our business.

Our business involves the receipt, storage, and transmission of confidential information about our customers, such as sensitive personal, account and payment 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”). Additionally, to offer services to our customers and operate our business, we utilize a number of products and services, such as IT networks and systems, including those we own and operate as well as others provided by third-party providers, such as cloud services (collectively, “Systems”).

We are subject to persistent cyberattacks and threats to our business from a variety of bad actors, many of whom attempt to gain unauthorized access to and compromise Confidential Information and Systems. In some cases, the bad actors exploit bugs, errors, misconfigurations or other vulnerabilities in our Systems to obtain Confidential Information. In other cases, these bad actors may obtain unauthorized access to Confidential Information utilizing credentials taken from our customers, employees, or third-party providers through credential harvesting, social engineering or other means. Other bad actors aim to cause serious operational disruptions to our business and Systems through ransomware or distributed denial of services attacks.

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

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

In August 2021, we disclosed that our systems were subject to a criminal cyberattack that compromised certain data of millions of our current customers, former customers, and prospective customers, including, in some instances, social security numbers,

53

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 “Recent Cyberattacks” in the Overview section of our Management’s Discussion and Analysis of Financial Condition and Results of Operations. As a result of the August 2021 cyberattack, we are subject to numerous claims, lawsuits and regulatory inquiries, the ongoing costs of which may be material, and we may be subject to further regulatory inquiries and private litigation. For more information, see “– Contingencies and Litigation – Litigation and Regulatory Matters” in Note 13 – Commitments and Contingencies of the Notes to the Consolidated Financial Statements.

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

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

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

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. We also expect that threat actors will continue to gain sophistication including in the use of tools and techniques (such as artificial intelligence) that are specifically designed to circumvent security controls, evade detection, and obfuscate forensic evidence, making it more challenging for us to identify, investigate and recover from future cyberattacks in a timely and effective manner. If we fail to protect Confidential Information or to prevent operational disruptions from future cyberattacks, there may be a material adverse effect on our business, reputation, financial condition, cash flows, and operating results.

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

In connection with the closing of the Prepaid Transaction, we and DISH entered into certain arrangements, including a Master Network Services Agreement (the “MNSA”) and a License Purchase Agreement (as amended, the “DISH License Purchase Agreement”). Pursuant to the MNSA, DISH will receive network services from the Company for a period of seven years. As set forth in the MNSA, the Company provides DISH, among other things, (a) legacy network services for certain Boost Mobile prepaid end users on the Sprint network, (b) T-Mobile network services for certain end users that have been migrated to the T-

54

Mobile network or provisioned on the T-Mobile network by or on behalf of DISH and (c) infrastructure mobile network operator services to assist in the access and integration of the DISH network. Pursuant to the DISH License Purchase Agreement, DISH has agreed to purchase all of Sprint’s 800 MHz spectrum (approximately 13.5 MHz of nationwide spectrum) for a total of approximately $3.6 billion. Pursuant to an amendment to the DISH License Purchase Agreement (the “LPS Amendment”) executed by us and DISH and approved by the Court along with a proposed amendment to the Final Judgment on October 23, 2023, if DISH fails to purchase such spectrum on or prior to April 1, 2024, then DISH’s sole liability will be that we can retain a non-refundable extension fee of approximately $100 million. In such instance, T-Mobile may be required to conduct an auction sale of all of Sprint’s 800 MHz spectrum under the terms set forth in the Final Judgment, but would not be required to divest such spectrum for an amount less than $3.6 billion.

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

Risks Related to Legal and Regulatory Matters

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

We and our affiliates are involved in various disputes, governmental and/or regulatory inspections, investigations and proceedings, mass arbitrations and litigation matters. Such legal proceedings can be complex, costly, and highly disruptive to our business operations by diverting the attention and energy of management and other key personnel.

In connection with the Transactions, we became subject to a number of legal proceedings, including a putative shareholder class action and derivative lawsuit and a putative antitrust class action. For more information, see “– Contingencies and Litigation – Litigation and Regulatory Matters” in Note 13 – Commitments and Contingencies of the Notes to the Consolidated Financial Statements. It is possible that stockholders of T-Mobile and/or Sprint may file additional putative class action lawsuits or shareholder derivative actions against the Company and the legacy T-Mobile board of directors and/or the legacy Sprint board of directors. Among other remedies, these stockholders could seek damages. The outcome of any litigation is uncertain, and any such potential lawsuits could result in substantial costs and may be costly and distracting to management.

Additionally, on April 1, 2020, in connection with the closing of the Merger, we assumed the contingencies and litigation matters of Sprint. Those matters include a wide variety of disputes, claims, government agency investigations and enforcement actions and other proceedings. Unfavorable resolution of these matters could require us to make additional reimbursements and pay additional fines and penalties.

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

As a result of the August 2021 cyberattack, we are subject to numerous lawsuits, including consolidated class action lawsuits seeking unspecified monetary damages, mass consumer arbitrations, a shareholder derivative lawsuit and inquiries by various government agencies, law enforcement and other governmental authorities, and we may be subject to further regulatory inquiries and private litigation. We are cooperating fully with regulators and vigorously defending against the class actions and other lawsuits. On July 22, 2022, we entered into an agreement to settle the consolidated class action lawsuit. On June 29, 2023, the Court issued an order granting final approval of the settlement, which is subject to potential appeals. Under the terms of the settlement, we would pay an aggregate of $350 million to fund claims submitted by class members, the legal fees of plaintiffs’ counsel and the costs of administering the settlement. We would also commit to an aggregate incremental spend of $150 million for data security and related technology in 2022 and 2023. We previously paid $35 million for claims administration purposes. On July 31, 2023, a class member filed an appeal to the final approval order challenging the Court’s award of attorneys’ fees to class counsel. We expect the remaining portion of the $350 million settlement payment to fund claims to be made once that appeal is resolved. In connection with the class action settlement and other settlements of separate consumer claims that have been previously completed or are currently pending, we recorded a total pre-tax charge of approximately $400 million during

55

the three months ended June 30, 2022. In light of the inherent uncertainties involved in such matters and based on the information currently available to us, we believe it is reasonably possible that we could incur additional losses associated with these proceedings and inquiries, and we will continue to evaluate information as it becomes known and will record an estimate for losses at the time or times when it is both probable that a loss has been incurred and the amount of the loss is reasonably estimable. In addition, in connection with the January 2023 cyberattack, we have received notices of consumer class actions and regulatory inquires, to which we will continue to respond in due course. Ongoing legal and other costs related to these proceedings and inquiries, as well as any potential future proceedings and inquiries related to the August 2021 cyberattack and the January 2023 cyberattack, may be substantial, and losses associated with any adverse judgments, settlements, penalties or other resolutions of such proceedings and inquiries could be significant and have a material adverse impact on our business, reputation, financial condition, cash flows and operating results.

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

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

Risks Related to Ownership of Our Common Stock

We cannot guarantee that our 2023-2024 Stockholder Return Program will be fully utilized, and our share repurchases and dividend payments pursuant thereto may fail to have the desired impact on stockholder value.

Our Board of Directors has authorized the 2023-2024 Stockholder Return Program for up to $19.0 billion that will run through December 31, 2024. The 2023-2024 Stockholder Return Program is expected to consist of additional repurchases of shares of our common stock and payment of cash dividends. The existence of the 2023-2024 Stockholder Return Program could cause our stock price, in certain cases, to be higher or lower than it otherwise would be and could potentially reduce the market liquidity or have other unintended consequences for our stock. In addition to the approximately $750 million dividend we declared on September 25, 2023, which is payable on December 15, 2023 to stockholders of record as of the close of business on December 1, 2023, we intend to declare and pay approximately $3.0 billion in total additional dividends in 2024, with payments occurring each quarter during the year. The dividend amount paid per share is expected to grow by around 10% annually, however, the declaration and payment of future dividends is subject to the discretion of our Board of Directors and will depend on financial and legal requirements and other considerations. The amount available under the 2023-2024 Stockholder Return Program for share repurchases will be reduced by the amount of any cash dividends declared by the Company.

Under the 2023-2024 Stockholder Return Program, share repurchases can be made from time to time using a variety of methods, which may include open market purchases, Rule 10b5-1 plans, accelerated share repurchases, privately negotiated transactions or otherwise, all in accordance with the rules of the Securities and Exchange Commission and other applicable legal requirements. The specific timing and amount of any share repurchases, and the specific timing and amount of any dividend payments, under the 2023-2024 Stockholder Return Program will depend on prevailing share prices, general economic and market conditions, Company performance and other considerations. In addition, the specific timing and amount of any dividend payments are subject to declaration on future dates by the Board in its sole discretion. The 2023-2024 Stockholder Return Program does not obligate the Company to acquire any particular amount of common stock or to declare and pay any particular amount of dividends, and the 2023-2024 Stockholder Return Program may be suspended or discontinued at any time at the Company’s discretion.

In addition, the threshold price that would trigger the issuance of additional shares of T-Mobile common stock to SoftBank under the Letter Agreement is subject to downward adjustment by the per share amount of any cash dividends or other cash distributions declared or paid on the Company’s common stock during the measurement period set forth in the Letter Agreement. As a result, any declaration of cash dividends could potentially result in the issuance of shares of T-Mobile

common stock to SoftBank under the Letter Agreement based on the lower threshold price that would not otherwise occur without the cash dividends, which would cause the interests of our stockholders to be diluted.

On September 6, 2023, our Board of Directors authorized our 2023-2024 Stockholder Return Program of up to an additional $19.0 billion that will run through December 31, 2024. The amounts presented represent the remaining shares authorized for purchase under the 2022 Stock Repurchase Program and the 2023-2024 Stockholder Return Program as of the end of the period. The amount available under the 2023-2024 Stockholder Return Program for share repurchases has been reduced by the $745 million of cash dividends declared by us on September 25, 2023.

On May 3, 2023, the SEC adopted amendments to modernize share repurchase disclosure requirements, including requiring issuers to disclose daily share repurchase activity in an exhibit to their Form 10-Q and Form 10-K. We will be required to comply with the amendments beginning with our first filing that covers the first full fiscal quarter that begins on October 1, 2023. We plan to apply the applicable amendments, including the discontinuation of the monthly share repurchase activity in this Item and replacing with daily share repurchase activity as an exhibit to our Form 10-Qs and Form 10-Ks, beginning in our Form 10-K for the year ending December 31, 2023.

RE: Eligibility for Certain Payments and Benefits

Dear Peter:

This letter (the “Letter”) outlines certain payments and benefits that you will be eligible for upon your retirement from T-Mobile US, Inc. (the “Company”) on February 1, 2024 (the “Retirement Date”, and your retirement on the Retirement Date, the “Retirement”).

1.STI Award: Notwithstanding anything in the T-Mobile US, Inc. 2013 Omnibus Incentive Plan, as amended from time to time, and any successor plan thereto (the “Omnibus Plan”) or in the award agreement between you and the Company evidencing the grant of a short-term annual incentive award for the 2024 calendar year (the “2024 STI Award”, and such agreement, the “STI Award Agreement”), upon your Retirement, the Company will pay you a pro-rated 2024 STI Award, calculated based on target performance, and pro-rated based on the number of days you were employed by the Company during the 2024 calendar year (the “Pro-Rata STI Award”). The Pro-Rata STI Award will be paid to you within seventy-four (74) days following the Retirement Date. For the avoidance of doubt, in accordance with the terms of the award agreement between you and the Company evidencing the grant of a short-term annual incentive award for the 2023 calendar year (the "2023 STI Award", and together with the 2024 STI Award, the "STI Awards"), the 2023 STI Award, to the extent earned by you in accordance with the terms and conditions of such award agreement and unpaid as of your Retirement Date, will be paid to you on the date on which short-term annual incentive awards for calendar year 2023 are paid to similarly situated executives of the Company.

2.RSUs and PRSUs: Notwithstanding anything in the Omnibus Plan or in any award agreement between you and the Company evidencing the grant of an award of time-based restricted stock units ("RSUs") or performance-based restricted stock units (“PRSUs”) (as applicable) (each, an "LTI Award Agreement'') (including any continued employment or continued service requirements set forth therein that would, absent this Letter, apply to the vesting and payment of your then-outstanding RSUs or PRSUs, as applicable), (a) no further RSUs or PRSUs shall be granted to you following the date of this Letter, and (b) upon your Retirement, your then-outstanding RSUs and PRSUs will be subject to the following provisions:

a.RSUs. Upon your Retirement, your then-outstanding and unvested RSUs will remain outstanding and will continue to vest and be paid to you in accordance with the terms of the applicable LTI Award Agreement.

b.PRSUs. Upon your Retirement, your then-outstanding and unvested PRSUs will remain outstanding and will continue to be eligible to vest and be paid to you in accordance with the terms of the applicable LTI Award Agreement; provided, however, that the

EXHIBIT 10.3

number of PRSUs that vest and become payable to you, and the Adjustment Percentage (as defined in the applicable LTI Award Agreement), shall be determined based on the lesser of (i) the actual level of attainment of the applicable performance measures during the applicable Performance Period (as defined in the applicable LTI Award Agreement), as determined by the Company following the conclusion of the Performance Period, or (ii) the actual level of attainment of the applicable performance measures during the portion of the applicable Performance Period ending on the Retirement Date (i.e., determined as if the applicable Performance Period had ended on the Retirement Date), as determined by the Company.

c.Death; Disability. Notwithstanding Sections 2(a) and (b) above, in the event of your death or Disability (as defined in the Omnibus Plan) following your Retirement but prior to the last date on which any RSUs and PRSUs become vested in accordance with Sections 2(a) and (b) above, your then-outstanding and unvested RSUs and PRSUs will vest in full (without pro-ration and, with respect to the PRSUs, at the target level of performance) on the date of your death or Disability and be paid to you within sixty (60) days following the date of such death or Disability.

3.COBRA Benefits: During the period commencing on the Retirement Date and ending on the earlier of the end of the last day of the eighteenth (18th) calendar month following the Retirement Date or, if earlier, the date on which you become eligible for coverage under a subsequent employer’s group medical and dental plans (in either case, the “COBRA Period”), subject to your valid election to continue healthcare coverage under Section 4980B of the Internal Revenue Code of 1986, as amended (the “Code”), and the regulations thereunder, the Company will continue to provide to you and your dependents, at the Company’s sole expense, coverage under its group medical and dental plans at the same levels in effect on the Retirement Date; provided, however, that if (a) any plan pursuant to which such benefits are provided is not, or ceases prior to the expiration of the continuation coverage period to be, exempt from the application of Section 409A of the Code under Treasury Regulation Section 1.409A-1(a)(S), (b) the Company is otherwise unable to continue to cover you or your dependents under its group health plans, or (c) the Company cannot provide the benefit without violating applicable law (including, without limitation, Section 2716 of the Public Health Service Act), then, in any such case, an amount equal to the dollar value of the balance of the Company’s subsidy shall thereafter be paid to you in substantially equal, then-currently-taxable monthly instalments over the COBRA Period (or remaining portion thereof) (collectively, the “COBRA Benefits”).

4.Continued Mobile Service Discount: Following your Retirement, you shall continue to be eligible for the Company’s employee mobile service discount program, in accordance with the terms of such program as in effect from time to time during such period (the “Continued Mobile Discounts”).

5.Release Requirement and Restrictive Covenants: Notwithstanding anything herein or in any applicable STI Award Agreement and any LTI Award Agreement (collectively, the "Award Agreements") to the contrary, you will not be eligible to receive any of the payments and benefits described in Sections 1 through 4 (other than the 2023 STI Award) above unless (i) you execute and do not revoke a release of claims in a form prescribed by the Company (the “Release”) that becomes effective and irrevocable no later than sixty (60) days following the Retirement Date (the date on which such Release becomes effective and irrevocable, the

EXHIBIT 10.3

"Release Effective Date'') and (ii) you continue to comply with the terms and conditions of the Restrictive Covenant Agreement (as defined below), subject to written notice and an opportunity to cure any noncompliance if reasonably capable of cure no later than ten (10) days following your receipt of such notice.

If the aggregate period during which you are entitled to consider and/or revoke the Release spans two calendar years, no payments under this Letter will be made prior to the beginning of the second such calendar year (and any payments otherwise payable prior thereto (if any) will instead be paid on the first regularly scheduled Company payroll date occurring in the latter such calendar year or, if later, on the first regularly scheduled Company payroll date following the Release Effective Date).

6.Exclusions; Amendment; No Other Modifications: Your Award Agreements will be deemed amended to the extent necessary to reflect this Letter. Except as otherwise expressly set forth in this Letter, the terms and conditions set forth in the Omnibus Plan and the Award Agreements will continue to apply to your STI Awards, RSUs and PRSUs following the date of this Letter.

7.Restrictive Covenants: Notwithstanding anything herein or in the Restrictive Covenant and Confidentiality Agreement between you and T-Mobile USA, Inc.(the “Restrictive Covenant Agreement”), the duration of the post-termination "Restricted Period" (as defined in Section 4 of the Restrictive Covenant Agreement) is hereby increased such that it shall extend through the later of one (1) year following your Retirement Date or the last date on which any RSUs and/or PRSUs are paid to you in accordance with the terms of this Letter.

8.Acknowledgement:You acknowledge and agree that during the period between the date of this Letter and the Retirement Date, the Company may change your title and/or your duties, authority or responsibility on behalf of the Company, and any such change shall not be a breach by the Company, of or constitute "good reason" (or any term of comparable effect) under, any agreement between you and the Company or its affiliates or any other plan, program or policy of the Company or its affiliates.

9.No Right to Continued Employment: Nothing contained in this Letter shall confer upon you any right to continue in the employ or service of the Company or affect the right of the Company to terminate your employment or service at any time.

10.No Tax Advice: The Company is not making any warranties or representations to you with respect to the income tax consequences associated with this Letter, the treatment of your STI Awards, RSUs and/or PRSUs contemplated hereunder, the COBRA Benefits or the Continued Mobile Discounts and you are in no manner relying on the Company, its affiliates or any of their respective representatives for an assessment of such tax consequences. You are hereby advised to consult with your own tax advisor with respect to any tax consequences associated with this Letter.

11.Governing Law: This Letter shall be governed by and construed in accordance with the laws of the State of Delaware without giving effect to the principles of conflicts of laws, and applicable federal law.

EXHIBIT 10.3

12.Section 409A: Notwithstanding anything to the contrary in the Omnibus Plan, any LTI Award Agreement or this Letter, if the Company determines that paying any amounts to you in respect of your RSUs and/or PRSUs at the time(s) indicated in any LTI Award Agreement or this Letter (as applicable) would be a prohibited distribution under Section 409A(a)(2)(B)(i) of the Code, then no such payment shall be paid to you prior to the expiration of the six (6)-month period following your "separation from service" with the Company (within the meaning of Section 409A of the Code) if you are a "specified employee" (within the meaning of Section 409A of the Code) on the date of your separation from service (such a delay, the “Six Month Delay”). If the payment of any such amount is subject to the Six Month Delay, then on the first business day following the end of such six (6) month period (or such earlier date upon which such amount can be paid under Section 409A without resulting in a prohibited distribution, including as a result of your death), the Company shall pay you a lump-sum amount equal to the cumulative amounts that would have otherwise been payable to you during such six (6)-month period (without interest). As of the date of this Letter, the Company intends that the RSUs will be subject to the Six Month Delay and the PRSUs will not be subject to the Six Month Delay. For the purposes of Section 409A of the Code, any right to a series of installment payments pursuant to this Agreement shall be treated as a right to a series of separate payments, and each RSU or PRSU (and any amounts payable in respect thereof) shall be treated separately from each other RSU and PRSU (and any amounts arising in connection therewith).

13.Miscellaneous: This Letter, together with the Omnibus Plan and the Award Agreements, sets forth the final and entire agreement of the parties with respect to the subject matter hereof and supersedes all prior agreements, promises, covenants, arrangements, communications, representations or warranties, whether oral or written, by the Company and you, or any representative of the Company or you, with respect to the subject matter hereof. This Letter may be amended at any time by the Company, provided that no amendment may, without your consent, materially impair your rights under any Award Agreement. This Letter may be executed in one or more counterparts, each of which will be deemed to be an original but all of which together will constitute one and the same instrument.

EXHIBIT 10.3

As of the date hereof, such Comcast Party has no Knowledge of any basis for any application, action, petition, objection or other pleading, or for any proceeding with the FCC or any other Governmental Authority, which (i) questions or contests the validity of, or seeks the revocation, forfeiture, non-renewal or suspension of, any such License, (ii) seeks the imposition of any modification or amendment with respect to any such License, (iii) seeks the payment of a fine, sanction, penalty, damages or contribution in connection with the use of any such License, or (iv) in any other way will or would reasonably be expected to adversely

The T-Mobile Parties (and their respective agents) shall be entitled to deduct and withhold from the amounts payable or otherwise deliverable pursuant to this Agreement such amounts as are required to be deducted or withheld therefrom under the Code or under any provision of state, local or foreign Tax Law; provided that the Comcast Parties shall be entitled to any refund of such amounts received with respect to any pre-Closing period.

(ii)by T-Mobile, by written notice to Comcast, at any time if, with respect to such Licenses, (A) any of a Comcast Party’s representations and warranties contained in this Agreement fails to be true and correct as of the applicable Closing Date, and such failure would result in the failure of the Comcast Parties to meet the conditions set forth in Section 6.1(e), or (B) a Comcast Party fails to comply with any of its covenants or obligations set forth herein, and such failure to comply would result in the failure of the condition set forth in Section 6.1(f); provided that T-Mobile shall have given the Comcast Parties written notice of such failure, such Comcast Party shall not have cured such failure (if curable) within thirty (30) days after receipt of such notice, and the T-Mobile Parties are not then in material breach of this Agreement;

18

(v)by either Party, by written notice to the other Party, if the consummation of the transactions contemplated hereby with respect to such Licenses shall be prohibited by a final, non-appealable order, decree or injunction of a court of competent jurisdiction or of the FCC, the DOJ or the FTC, or if the FCC designates for hearing the FCC Application with respect to such Licenses;

(vi)automatically, with respect to any such License for which the Lease has been terminated; provided that, if such termination is pursuant to Section 7(d)(vii) of the Lease and the Lease is ultimately reinstated with respect to such Licenses, such termination of this Agreement shall immediately become null and void; or

19

satisfied in accordance with such resolution. It is the express intent of the Parties to modify the applicable statute of limitations to the extent set forth in this Section 8.1.

Section 8.2General Indemnification Obligation

(a)From and after each Closing, each Party (the “Indemnifying Party”) agrees to indemnify, hold harmless and reimburse the other Party (i.e., each of the T-Mobile Parties or the Comcast Parties, as the case may be) and its Affiliates, and its and their respective shareholders, partners, directors, officers, members, managers, agents, employees, successors and assigns (each, an “Indemnified Party”) against and in respect of any and all damages, losses, deficiencies, liabilities, assessments, fines, judgments, costs and other expenses (including reasonable legal fees and expenses and reasonable expenses of investigation) (“Losses”) incurred or suffered by any Indemnified Party, whether such Losses relate to claims, actions or causes of action asserted by any Indemnified Party against the Indemnifying Party or asserted by third parties, that result from, relate to or arise out of the following, in each case, as it relates to the Licenses subject to such Closing:

(i)any inaccuracy in or breach of the representations and warranties made by the Indemnifying Party herein or in any certificate delivered by the Indemnifying Party at such Closing; or

(ii)any nonfulfillment or breach by the Indemnifying Party of any of the covenants or agreements made by the Indemnifying Party herein.

(b)From and after each Closing, each Comcast Party as Indemnifying Party agrees to indemnify, hold harmless and reimburse the T-Mobile Parties and their Affiliates, and the T-Mobile Parties’ and their Affiliates’ respective shareholders, partners, directors, officers, agents, employees, successors and assigns, as Indemnified Parties, against and in respect of any and all Losses incurred or suffered by any such Indemnified Party that result from, relate to or arise out of: (i) the ownership and use by such Comcast Party or its Affiliates of the Licenses subject to such Closing prior to such Closing; or (ii) any Liabilities of a Comcast Party or any of its Affiliates relating to such Licenses, unless separately assumed or transferred or subject to indemnification by the T-Mobile Parties and their Affiliates pursuant to an agreement unrelated to this Agreement, in each case, excluding Losses arising from or in connection with (x) the Lease or the use or operation of the Licenses by T-Mobile License or its Affiliates thereunder or under any emergency special temporary authorization granted by the FCC or (y) the Assumed Liabilities.

(c)From and after each Closing, the T-Mobile Parties as Indemnifying Party agree to indemnify, hold harmless and reimburse each Comcast Party and its Affiliates, and such Comcast Party’s and its Affiliates’ respective shareholders, partners, directors, officers, members, managers, agents, employees, successors and assigns, as Indemnified Parties, against and in respect of any and all Losses incurred or suffered by any such Indemnified Party that result from, relate to or arise out of: (i) the ownership and use by T-Mobile License or other T-Mobile Affiliates of the Licenses subject to such Closing after such Closing; or (ii) any Liabilities of a T-Mobile Party or any of its Affiliates relating to such Licenses, including the Assumed Liabilities, unless separately assumed or transferred or subject to indemnification by the Comcast Parties and their Affiliates pursuant to an agreement unrelated to this Agreement.

Section 8.3Limitations

(a)No Indemnifying Party shall have any obligation to indemnify any Indemnified Party against any Losses pursuant to Section 8.2(a)(i) (other than with respect to inaccuracies in

20

or breaches of an Indemnifying Party’s Fundamental Representations) unless and until (i) any such Losses arising out of a single set of (or series of related) facts and circumstances exceeds $50,000, and (ii) the aggregate amount of all such Losses of the Indemnified Parties with respect to a License exceeds the amount that is one percent (1%) of the amount set forth in the “Purchase Price Allocation” column on Schedule A in respect of such License, and, in the case of either clause (i) or clause (ii), such Indemnifying Party shall only be liable to the Indemnified Parties for Losses in excess of each such threshold. The aggregate amount of all Losses for which an Indemnifying Party shall be liable pursuant to Section 8.2(a)(i) (other than with respect to inaccuracies in or breaches of an Indemnifying Party’s Fundamental Representations) with respect to a License shall not exceed the amount that is ten percent (10%) of the amount set forth in the “Purchase Price Allocation” column on Schedule A in respect of such License. In no event shall the aggregate liability of either the Comcast Parties or the T-Mobile Parties for any Losses pursuant to Section 8.2(a) exceed the aggregate amount paid to the Comcast Parties hereunder with respect to the specific Licenses that are the subject of the breaches that gives rise to such Losses.

(b)For all purposes of this Article 8, including whether or not any inaccuracy in or breach of any representation or warranty has occurred and the amount of Losses resulting from, relating to or arising out of any such inaccuracy or breach, any materiality, material adverse effect or other similar qualification contained in or otherwise applicable to such representation or warranty shall be disregarded.

(c)Notwithstanding any other provisions of this Agreement (but without limiting Section 8.6), in no event shall any Party be liable for any Losses under this Article 8 that are exemplary or punitive, or otherwise not constituting actual direct Losses, regardless of the theory of recovery; provided that this Section 8.3(c) shall not apply to any damages actually paid to third parties pursuant to a final judicial order.

(d)Each Indemnified Party shall take, and cause its Affiliates to take, all reasonable steps to mitigate any Losses indemnifiable under this Article 8 upon becoming aware of any event or circumstance that would be reasonably expected to, or does, give rise thereto, including incurring costs only to the minimum extent necessary to remedy the breach that gives rise to such Losses (it being understood that reasonable costs incurred in furtherance thereof shall, subject to the terms, conditions and limitations herein, constitute indemnifiable Losses to the extent such costs mitigate such Losses). The amount of any Losses for which an Indemnified Party claims indemnification under this Agreement shall be reduced by: (i) any insurance proceeds actually received by the Indemnified Party with respect to such Losses (net of any increases in premiums or other costs attributable thereto); and (ii) any indemnification or reimbursement payments actually received by the Indemnified Party from third parties (other than insurers) with respect to such Losses (net of any costs attributable thereto).

(e)Each Party acknowledges and agrees that the Licenses are unique and that, prior to each Closing, remedies at law, including monetary damages, will be inadequate in the event of a breach by it in the performance of its obligations under this Agreement with respect to the Licenses subject to such Closing. Accordingly, each Party agrees that in the event of any such breach, the other Party shall be entitled to a decree of specific performance pursuant to which such Party is ordered to affirmatively carry out its pre-Closing and Closing obligations under this Agreement with respect to such Licenses, subject to the conditions of this Agreement. The foregoing shall not be deemed to be or construed as a waiver or election of remedies by either Party, and each Party expressly reserves any and all rights and remedies available to it at law or in equity in the event of any breach or default by the other Party under this Agreement.

21

Section 8.4Indemnification Procedures

(a)Any party seeking indemnification pursuant to this Article 8 shall promptly notify in writing (in accordance with the provisions of Section 9.5) (a “Claim Notice”) the other party or parties from whom such indemnification is sought of a third party’s assertion of any claim with respect to which the indemnification provisions set forth in this Article 8 relate, providing in reasonable detail the facts giving rise to such claim, a statement of the Indemnified Party’s Losses to the extent then known, and an estimate of the amount of Losses that the Indemnified Party reasonably anticipates it will suffer or incur, provided, however, that no delay on the part of the Indemnified Party in giving the Claim Notice shall relieve the Indemnifying Party from any obligation hereunder unless (and solely to the extent) the Indemnifying Party is prejudiced thereby.

(b)Upon receipt of a Claim Notice, the Indemnifying Party shall have the right, upon written notice to the Indemnified Party within twenty (20) Business Days after its receipt of any Claim Notice, to undertake the control and defense of such claim if the Indemnifying Party acknowledges in writing that, based on the facts set forth in the applicable Claim Notice, the Indemnifying Party would have an indemnification obligation for Losses arising out of the applicable third-party claim (subject to the terms, conditions and limitations herein); provided, however, that (x) the Indemnifying Party shall consult with the Indemnified Party in good faith relating to the defense of such claim; and (y) the Indemnifying Party shall not have the right to assume the defense of any portion of such claim that is criminal in nature or seeks non-de minimis injunctive relief. If the Indemnifying Party has undertaken the defense of any such claim, the Indemnifying Party may not agree to any settlement or compromise of such claim without the prior written consent of the Indemnified Party unless (i) in connection with such settlement or compromise, the Indemnifying Party acknowledges in writing its obligation to pay in full the amount of the settlement or compromise and all associated expenses (notwithstanding any of the limitations in this Article 8 to the contrary), (ii) the settlement or compromise does not involve anything but the one-time payment of money, and (iii) the Indemnifying Party obtains, at no cost to the Indemnified Party, a release executed and delivered by the claiming third party or parties of all claims against the Indemnified Party and its Affiliates in connection with the applicable claim. Subject to the foregoing, if the Indemnified Party has undertaken the defense of any such claim, the Indemnified Party may not agree to any settlement or compromise of such claim without the prior written consent of the Indemnifying Party (not to be unreasonably withheld, conditioned or delayed); provided that such consent shall not be required if (x) the settlement or compromise does not involve anything but the one-time payment of money for which the Indemnified Party shall be solely responsible (and in respect of which the Indemnified Party waives all claims against the Indemnifying Party and its Affiliates), and (y) the Indemnified Party obtains, at no cost to the Indemnifying Party, a release executed and delivered by the claiming third party or parties of all claims against the Indemnifying Party and its Affiliates in connection with the applicable claims. In no event shall the party that has undertaken the defense of any such claim in accordance with the foregoing be required to agree to any settlement or compromise of any such claim.

(c)In the event an Indemnified Party has a claim against the Indemnifying Party hereunder that does not involve a claim or demand being asserted against or sought to be collected from it by a third party, the Indemnified Party shall promptly send a Claim Notice with respect to such claim to the Indemnifying Party.

(d)The failure of the Indemnified Party to give the Indemnifying Party a Claim Notice in accordance with the requirements of this Article 8 shall not relieve the Indemnifying Party from any liability in respect of such claim, demand or action under this Article 8, except to the extent of any prejudice or damages to the Indemnifying Party as a result thereof.

22

Section 8.5Treatment of Payments

Any payment made pursuant to the indemnification obligations arising under Section 8.2 shall be treated as an adjustment to the Applicable Purchase Price to the extent permitted under applicable Law.

Section 8.6Exclusive Remedy

Following each Closing, the Parties acknowledge and agree that the indemnification rights of the Parties and their Affiliates under this Article 8 are their exclusive remedy with respect to any and all claims arising out of or in relation to this Agreement and the Transaction Documents, in each case, as it relates to the Licenses subject to such Closing; provided that nothing in this Article 8 or otherwise in this Agreement shall limit any Party’s equitable remedies or any Party’s rights or remedies based on actual and intentional fraud under New York law (or, for the avoidance of doubt, any Losses payable in accordance with Section 7.1(b)).

ARTICLE 9

After giving effect to such assignment, such assignee shall be a “T-Mobile Party” for purposes of this Agreement.

Section 9.2Further Assurances

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Summary of Significant Accounting Policies

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, 2022.

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. Estimates are inherently subject to judgment and actual results could differ from those estimates.

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

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

Dividends

On September 6, 2023, our Board of Directors authorized a stockholder return program of up to $19.0 billion that will run through December 31, 2024 (the “2023-2024 Stockholder Return Program”). The 2023-2024 Stockholder Return Program is expected to consist of additional repurchases of shares of our common stock and the payment of cash dividends. The amount available under the 2023-2024 Stockholder Return Program for share repurchases will be reduced by the amount of any cash dividends declared by us.

Dividends declared are included as a reduction to Retained earnings on our Condensed Consolidated Balance Sheets. We recognize a liability for dividends declared but for which cash has not been paid in Other current liabilities on our Condensed Consolidated Balance Sheets. Dividend cash payments to stockholders will be included in Net cash (used in) provided by financing activities on our Condensed Consolidated Statements of Cash Flows. See Note 10 - Stockholder Return Programs for more information about our 2023-2024 Stockholder Return Program.

Accounting Pronouncements Adopted During the Current Year

Troubled Debt Restructurings and Vintage Disclosures

In March 2022, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2022-02, “Financial Instruments—Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures.” The standard eliminates the accounting guidance within ASC 310-40 for troubled debt restructurings by creditors while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty. Additionally, for public business entities, the standard requires disclosure of current-period gross write-offs by year of origination for financing receivables and net investments in leases within the scope of ASC 326-20. As of January 1, 2023, we have adopted this standard, and it was applied prospectively after this date. This standard did not have a material impact on our condensed consolidated financial statements as of and for the three and nine months ended September 30, 2023.

Business Combination and Asset Acquisition [Abstract]

Business Combination

Note 2 – Business Combination

On March 9, 2023, we entered into a Merger and Unit Purchase Agreement for the acquisition of 100% of the outstanding equity of Ka’ena Corporation and its subsidiaries including, among others, Mint Mobile LLC, for a maximum purchase price of $1.35 billion to be paid out 39% in cash and 61% in shares of T-Mobile common stock. The purchase price is variable dependent upon specified performance indicators of Ka’ena Corporation during certain periods before and after closing and consists of an upfront payment at closing of the transaction, subject to certain agreed-upon adjustments, and a variable earnout payable 24 months after closing of the transaction. Our estimate of the upfront payment is subject to Ka’ena Corporation’s underlying business performance and the timing of transaction close, and has been updated to $1.2 billion, before working capital adjustments. The acquisition is subject to certain customary closing conditions, including certain regulatory approvals, and is expected to close by the end of the first quarter of 2024.

Receivables and Related Allowance for Credit Losses

Receivables [Abstract]

Receivables and Related Allowance for Credit Losses

Note 3 – Receivables and Related Allowance for Credit Losses

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

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

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

Accounts Receivable Portfolio Segment

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

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

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

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

EIP Receivables Portfolio Segment

Based upon customer credit profiles at the time of customer origination, we classify the EIP receivables segment into two customer classes of “Prime” and “Subprime.” Prime customer receivables are those with lower credit risk and Subprime customer receivables are those with higher credit risk. Customers may be required to make a down payment on their equipment purchases if their assessed credit risk exceeds established underwriting thresholds. In addition, certain customers within the Subprime category may be required to pay a deposit.

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

EIP receivables had a combined weighted-average effective interest rate of 9.9% and 8.0% as of September 30, 2023, and December 31, 2022, respectively.

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

(in millions)	September 30, 2023		December 31, 2022
EIP receivables, gross	$	7,089	$	8,480
Unamortized imputed discount	(453)		(483)
EIP receivables, net of unamortized imputed discount	6,636		7,997
Allowance for credit losses	(287)		(328)
EIP receivables, net of allowance for credit losses and imputed discount	$	6,349	$	7,669
Classified on our condensed consolidated balance sheets as:
Equipment installment plan receivables, net of allowance for credit losses and imputed discount	$	4,470	$	5,123
Equipment installment plan receivables due after one year, net of allowance for credit losses and imputed discount	1,879		2,546
EIP receivables, net of allowance for credit losses and imputed discount	$	6,349	$	7,669

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

The following table presents the amortized cost of our EIP receivables by delinquency status, customer credit class and year of origination as of September 30, 2023:

	Originated in 2023				Originated in 2022				Originated prior to 2022				Total EIP Receivables, Net of Unamortized Imputed Discounts

Current - 30 days past due	$	2,419	$	1,355	$	1,305	$	896	$	368	$	175	$	4,092	$	2,426	$	6,518

More than 90 days past due	5		9		5		11		2		3		12		23		35
EIP receivables, net of unamortized imputed discount	$	2,437	$	1,394	$	1,322	$	929	$	373	$	181	$	4,132	$	2,504	$	6,636

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

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

The following table presents write-offs of our EIP receivables by year of origination for the nine months ended September 30, 2023:

(in millions)	Originated in 2023		Originated in 2022		Originated prior to 2022		Total Write-offs
Write-offs	$	84	$	243	$	54	$	381

Activity for the nine months ended September 30, 2023 and 2022, in the allowance for credit losses and unamortized imputed discount balances for the accounts receivable and EIP receivables segments were as follows:

	September 30, 2023						September 30, 2022

Transfers and Servicing [Abstract]

Sales of Certain Receivables

Note 4 – Sales of Certain Receivables

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

Sales of EIP Receivables

Overview of the Transaction

In 2015, we entered into an arrangement to sell certain EIP receivables on a revolving basis (the “EIP sale arrangement”), which has been revised and extended from time to time. As of both September 30, 2023, and December 31, 2022, the EIP sale arrangement provided funding of $1.3 billion.

In connection with this EIP sale arrangement, we formed a wholly owned subsidiary, which qualifies as a bankruptcy remote entity (the “EIP BRE”). We consolidate the EIP BRE under the VIE model.

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

(in millions)	September 30, 2023		December 31, 2022
Other current assets	$	368	$	344
Other assets	114		136

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”). On February 28, 2023, we extended the scheduled expiration date of the service receivable sale arrangement to February 27, 2024. As of both September 30, 2023, and December 31, 2022, the service receivable sale arrangement provided funding of $775 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”). We consolidate the Service BRE under the VIE model.

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

(in millions)	September 30, 2023		December 31, 2022
Other current assets	$	210	$	214
Other current liabilities	355		389

Sales of Receivables

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

(in millions)	September 30, 2023		December 31, 2022
Derecognized net service accounts receivable and EIP receivables	$	2,426	$	2,410
Other current assets	578		558
of which, deferred purchase price	576		556
Other long-term assets	114		136
of which, deferred purchase price	114		136
Other current liabilities	355		389
Net cash proceeds since inception	1,604		1,697
Of which:
Change in net cash proceeds during the year-to-date period	(93)		(57)
Net cash proceeds funded by reinvested collections	1,697		1,754

At inception, we elected to measure the deferred purchase price at fair value with changes in fair value included in Selling, general and administrative expenses on 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 estimated customer default rates. As of September 30, 2023, and December 31, 2022, our deferred purchase price related to the sales of service accounts receivable and EIP receivables was $690 million and $692 million, respectively.

We recognized losses from sales of receivables, including changes in fair value of the deferred purchase price, of $46 million and $60 million for the three months ended September 30, 2023 and 2022, respectively, and $135 million and $168 million for the nine months ended September 30, 2023 and 2022, respectively, in Selling, general and administrative expenses on our Condensed Consolidated Statements of Comprehensive Income.

Continuing Involvement

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

the direction of the purchasers of the sold receivables, we apply the same policies and procedures while servicing the sold receivables as we apply to our owned receivables, and we continue to maintain normal relationships with our customers.

In September 2022, the Federal Communications Commission (“FCC”) announced that we were the winning bidder of 7,156 licenses in Auction 108 (2.5 GHz spectrum) for an aggregate price of $304 million. At inception of Auction 108 in June 2022, we deposited $65 million. We paid the FCC the remaining $239 million for the licenses won in the auction in September 2022. The aggregate cash payments made to the FCC are included in Other assets on our Condensed Consolidated Balance Sheets as of September 30, 2023, and will remain there until the corresponding licenses are received. The timing of when the licenses will be issued will be determined by the FCC after all post-auction procedures have been completed, and the FCC Chairwoman has stated that it is subject to the restoration of auction authority to the FCC by Congress.

As of September 30, 2023, the activities that are necessary to get the 3.45 GHz and 2.5 GHz spectrum, acquired pursuant to FCC Auctions 110 and 108, ready for its intended use have not begun; as such, capitalization of the interest associated with the costs of deploying these spectrum licenses has not begun. During the three months ended September 30, 2023, we began capitalizing interest on the costs of our C-band spectrum licenses, acquired pursuant to FCC Auction 107, as we have begun development activities necessary to prepare the spectrum for its intended use.

License Purchase Agreements

DISH Network Corporation

On July 1, 2020, we and DISH Network Corporation (“DISH”) entered into a license purchase agreement (the “DISH License Purchase Agreement”) pursuant to which DISH agreed to purchase certain 800 MHz spectrum licenses for a total of approximately $3.6 billion. The closing of the sale of spectrum under the DISH License Purchase Agreement remains subject to FCC approval. Subsequent to September 30, 2023, on October 15, 2023, we and DISH entered into an amendment (the “LPA Amendment”) to the DISH License Purchase Agreement pursuant to which, among other things, the parties agreed that (1) DISH will pay us a $100 million non-refundable extension fee (in lieu of the approximately $72 million termination fee that had previously been agreed to), (2) the closing for the purchase of the spectrum licenses by DISH will occur no later than April 1, 2024, (3) if DISH has not purchased the spectrum licenses by such date for any reason (including failure to receive the required FCC approval prior to such date), then the DISH License Purchase Agreement will automatically terminate, and we will retain the $100 million extension fee, (4) if DISH does purchase the spectrum by April 1, 2024, the $100 million extension fee will be credited against the $3.6 billion purchase price, and (5) permits us to commence auction of the spectrum prior to April 1, 2024 at our discretion (and subject to DISH’s purchase right). The LPA Amendment was approved by the Court and became effective on October 23, 2023.

If DISH does not, by April 1, 2024, purchase the 800 MHz spectrum licenses, we are required, unless otherwise approved under the final judgment agreed to by us, Deutsche Telekom AG (“DT”), Sprint Corporation, now known as Sprint LLC (“Sprint”), SoftBank Group Corp. (“SoftBank”) and DISH with the U.S. District Court for the District of Columbia, which was approved by the Court on April 1, 2020, to offer the licenses for sale through an auction. If the specified minimum price of $3.6 billion is not met in the auction, we would be relieved of the obligation to sell the licenses.

Channel 51 License Co LLC and LB License Co, LLC

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

On March 30, 2023, we and the Sellers entered into Amended and Restated License Purchase Agreements pursuant to which we and the Sellers agreed to separate the transaction into two tranches of licenses, with the closings on the acquisitions of certain licenses in Chicago, Dallas and New Orleans being deferred in order to potentially expedite the regulatory approval process for the remainder of the licenses. Subsequently, on August 25, 2023, we and the Sellers entered into Amendments No. 1 to the Amended and Restated License Purchase Agreements, which deferred the closings of certain additional licenses in Chicago and Dallas into the second closing tranche. Together, the licenses with closings deferred into the second closing tranche represent $1.1 billion of the aggregate $3.5 billion cash consideration. The licenses being acquired by us, and the total consideration being paid for the licenses, remains the same under the original License Purchase Agreements and subsequent amendments.

We anticipate that the first closing will occur no earlier than the first half of 2024 and that the second closing (on the deferred licenses) will occur in late 2024 or early 2025.

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

Comcast Corporation

On September 12, 2023, we entered into a License Purchase Agreement with Comcast Corporation and its affiliate, Comcast OTR1, LLC (together with Comcast Corporation, “Comcast”), pursuant to which we will acquire spectrum in the 600 MHz band from Comcast in exchange for total cash consideration of between $1.2 billion and $3.3 billion, subject to an application for FCC approval. The licenses will be acquired without any associated networks. We anticipate the closing will occur in the first half of 2028.

The final purchase price will be determined, in the aggregate and on a per license basis, based on the set of licenses subject to the License Purchase Agreement at the time the parties make required transfer filings with the FCC. Prior to the time of such filings, Comcast has the right to remove any or all of a certain specified subset of the licenses, totaling $2.1 billion (the “Optional Sale Licenses”), from the License Purchase Agreement. The removal of any Optional Sale Licenses would reduce the final purchase price by the assigned value of each such license, from the maximum purchase price of $3.3 billion.

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

Fair Value Measurements

Fair Value Disclosures [Abstract]

Fair Value Measurements

Note 6 – Fair Value Measurements

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

Derivative Financial Instruments

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

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

We did not have any significant derivative instruments outstanding as of September 30, 2023, or December 31, 2022.

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 $1.2 billion and $1.3 billion are presented in Accumulated other comprehensive loss on our Condensed Consolidated Balance Sheets as of September 30, 2023, and December 31, 2022, respectively.

For the three months ended September 30, 2023 and 2022, $55 million and $51 million, respectively, and for the nine months ended September 30, 2023 and 2022, $163 million and $151 million, respectively, were amortized from Accumulated other comprehensive loss into Interest expense, net, on our Condensed Consolidated Statements of Comprehensive Income. We expect to amortize $232 million of the Accumulated other comprehensive loss associated with the derivatives into Interest expense, net, over the 12 months ending September 30, 2024.

Deferred Purchase Price Assets

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

The carrying amounts of our deferred purchase price assets, which are measured at fair value on a recurring basis and are included on our Condensed Consolidated Balance Sheets, were $690 million and $692 million as of September 30, 2023, and December 31, 2022, respectively.

Debt

The fair value of our Senior Notes and spectrum-backed 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. The fair value of our asset-backed notes (“ABS Notes”) was primarily based on quoted prices in inactive markets for identical instruments and observable changes in market interest rates, both of which are Level 2 inputs. Accordingly, our ABS Notes were classified as Level 2 within the fair value hierarchy.

Although we have determined the estimated fair values using available market information and commonly accepted valuation methodologies, considerable judgment was required in interpreting market data to develop fair value estimates for the Senior Notes to affiliates and ABS Notes. The fair value estimates were based on information available as of September 30, 2023, and December 31, 2022. As such, our estimates are not necessarily indicative of the amount we could realize in a current market exchange.

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

(in millions)	Level within the Fair Value Hierarchy	September 30, 2023				December 31, 2022
		Carrying Amount		Fair Value		Carrying Amount (1)		Fair Value (1)
Liabilities:
Senior Notes to third parties	1	$	70,542	$	61,198	$	66,582	$	59,011
Senior Notes to affiliates	2	1,496		1,439		1,495		1,460
Senior Secured Notes to third parties	1	2,513		2,407		3,117		2,984
ABS Notes to third parties	2	747		739		746		744

(1)     Excludes $20 million as of December 31, 2022, in other financial liabilities as the carrying values approximate fair value, primarily due to the short-term maturities of these instruments.

4.910% Class A Senior ABS Notes due 2028	$	198	$	552

Variable Interest Entities

In connection with issuing the ABS Notes in October 2022, we formed a wholly owned subsidiary, which qualifies as a bankruptcy remote entity (the “ABS BRE”), and a trust (the “ABS Trust” and together with the ABS BRE, the “ABS Entities”), in which the ABS BRE holds a residual interest. The ABS Entities meet the definition of a VIE for which we have determined that we are the primary beneficiary as we have the power to direct the activities of the ABS Entities that most significantly impact their performance. Accordingly, we include the balances and results of operations of the ABS Entities in our condensed consolidated financial statements.

The following table summarizes the carrying amounts and classification of assets and liabilities included in our Condensed Consolidated Balance Sheets with respect to the ABS Entities:

(in millions)	September 30, 2023		December 31, 2022

See Note 3 – Receivables and Related Allowance for Credit Losses for additional information on the EIP receivables used to secure the ABS Notes.

Restricted Cash

Certain provisions of our debt agreements require us to maintain specified cash collateral balances. Amounts associated with these balances are considered to be restricted cash. See Note 15 - Additional Financial Information for our reconciliation of Cash and cash equivalents, including restricted cash and cash held for sale.

Commercial Paper

On July 25, 2023, we established an unsecured short-term commercial paper program with the ability to borrow up to $2.0 billion from time to time. This program supplements our other available external financing arrangements, and proceeds are expected to be used for general corporate purposes. As of September 30, 2023, there was no outstanding balance under this program.

Tower Obligations

9 Months Ended

Sep. 30, 2023

Leases [Abstract]

Tower Obligations

Note 8 – Tower Obligations

Existing CCI Tower Lease Arrangements

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

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

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

However, we also considered if this arrangement resulted in the sale of the CCI Lease Sites for which we would derecognize the tower assets. By assessing whether control had transferred, we concluded that transfer of control criteria, as discussed in the revenue standard, were not met. Accordingly, we recorded this arrangement as a financing whereby we recorded debt, a financial obligation, and the CCI Lease Sites tower assets remained on our 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. The tower obligations are increased by interest expense and amortized through contractual leaseback payments made by us to CCI and through net cash flows generated and retained by CCI from the operation of the tower sites.

Acquired CCI Tower Lease Arrangements

Prior to our merger (the “Merger”) with 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.

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

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

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

Leaseback Arrangement

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

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

(in millions)	September 30, 2023		December 31, 2022
Property and equipment, net	$	2,259	$	2,379
Tower obligations	3,819		3,934
Other long-term liabilities	554		554

Future minimum payments related to the tower obligations are approximately $432 million for the 12-month period ending September 30, 2024, $780 million in total for both of the 12-month periods ending September 30, 2025 and 2026, $804 million in total for both of the 12-month periods ending September 30, 2027 and 2028, and $4.2 billion in total thereafter.

We are contingently liable for future ground lease payments through the remaining term of the CCI Lease Sites and the Master Lease Sites. These contingent obligations are not included in Operating lease liabilities as any amount due is contractually owed by CCI based on the subleasing arrangement. Under the arrangement, we remain primarily liable for ground lease payments on approximately 900 sites and have included lease liabilities of $244 million in our Operating lease liabilities as of September 30, 2023.

Revenue from Contract with Customer [Abstract]

Revenue from Contracts with Customers

Note 9 – Revenue from Contracts with Customers

Disaggregation of Revenue

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

•Postpaid customers generally include customers who are qualified to pay after receiving wireless communications services utilizing phones, High Speed Internet, mobile internet devices, including tablets and hotspots, wearables, DIGITS or other connected devices, including SyncUP and IoT;

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

•Wholesale customers include Machine-to-Machine and Mobile Virtual Network Operator customers that operate on our network but are managed by wholesale partners.

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

	Three Months Ended September 30,				Nine Months Ended September 30,
(in millions)	2023		2022		2023		2022
Postpaid service revenues
Postpaid phone revenues	$	10,942	$	10,481	$	32,393	$	31,119
Postpaid other revenues	1,346		1,067		3,827		3,075
Total postpaid service revenues	$	12,288	$	11,548	$	36,220	$	34,194

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

Contract Balances

The contract asset and contract liability balances from contracts with customers as of September 30, 2023, and December 31, 2022, were as follows:

(in millions)	Contract Assets		Contract Liabilities
Balance as of December 31, 2022	$	534	$	748
Balance as of September 30, 2023	617		814
Change	$	83	$	66

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

Contract asset balances increased primarily due to an increase in promotions with an extended service contract, partially offset by billings on existing contracts and impairment, which is recognized as bad debt expense. The current portion of our contract assets of approximately $490 million and $356 million as of September 30, 2023, and December 31, 2022, respectively, was included in Other current assets on our Condensed Consolidated Balance Sheets.

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

Revenues for the three and nine months ended September 30, 2023 and 2022 include the following:

	Three Months Ended September 30,				Nine Months Ended September 30,
(in millions)	2023		2022		2023		2022
Amounts included in the beginning of year contract liability balance	$	24	$	17	$	730	$	702

Remaining Performance Obligations

As of September 30, 2023, the aggregate amount of transaction price allocated to remaining service performance obligations for postpaid contracts with subsidized devices and promotional bill credits that result in an extended service contract is $1.5 billion. We expect to recognize revenue as the service is provided on these postpaid contracts over an extended contract term of 24 months from the time of origination.

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

Certain of our wholesale, roaming and service contracts include variable consideration based on usage and performance. This variable consideration has been excluded from the disclosure of remaining performance obligations. As of September 30, 2023, the aggregate amount of the contractual minimum consideration for wholesale, roaming and service contracts is $395 million, $2.0 billion and $4.2 billion for 2023, 2024, and 2025 and beyond, respectively. These contracts have a remaining duration ranging from less than one year to eight years.

Contract Costs

The balance of deferred incremental costs to obtain contracts with customers was $2.1 billion and $1.9 billion as of September 30, 2023, and December 31, 2022, respectively, and is included in Other assets on our Condensed Consolidated Balance Sheets. Deferred contract costs incurred to obtain postpaid service contracts are amortized over a period of 24 months. The amortization period is monitored to reflect any significant change in assumptions. Amortization of deferred contract costs included in Selling, general and administrative expenses on our Condensed Consolidated Statements of Comprehensive Income were $468 million and $375 million for the three months ended September 30, 2023 and 2022, respectively, and $1.3 billion and $1.1 billion for the nine months ended September 30, 2023 and 2022, respectively.

The deferred contract cost asset is assessed for impairment on a periodic basis. There were no impairment losses recognized on deferred contract cost assets for the three and nine months ended September 30, 2023 and 2022.

2022 Stock Repurchase Program

On September 8, 2022, our Board of Directors authorized our 2022 Stock Repurchase Program for up to $14.0 billion of our common stock through September 30, 2023 (the “2022 Stock Repurchase Program”). During the three months ended September 30, 2023, we repurchased 19,313,159 shares of our common stock at an average price per share of $138.48 for a total purchase price of $2.7 billion, and during the nine months ended September 30, 2023, we repurchased 77,460,937 shares of our common stock at an average price per share of $141.57 for a total purchase price of $11.0 billion, all of which were purchased under the 2022 Stock Repurchase Program. All shares purchased during the nine months ended September 30, 2023, were purchased at market price.

2023-2024 Stockholder Return Program

On September 6, 2023, our Board of Directors authorized our 2023-2024 Stockholder Return Program of up to $19.0 billion that will run through December 31, 2024. The 2023-2024 Stockholder Return Program is expected to consist of additional repurchases of shares of our common stock and the payment of cash dividends. The amount available under the 2023-2024 Stockholder Return Program for share repurchases will be reduced by the amount of any cash dividends declared by us.

Under the 2023-2024 Stockholder Return Program, share repurchases can be made from time to time using a variety of methods, which may include open market purchases, Rule 10b5-1 plans, accelerated share repurchases, privately negotiated transactions or otherwise, all in accordance with the rules of the Securities and Exchange Commission and other applicable legal requirements. The specific timing and amount of any share repurchases, and the specific timing and amount of any dividend payments, under the 2023-2024 Stockholder Return Program will depend on prevailing share prices, general economic and market conditions, Company performance, and other considerations. In addition, the specific timing and amount of any dividend payments are subject to being declared on future dates by our Board of Directors in its sole discretion. The 2023-2024 Stockholder Return Program does not obligate us to acquire any particular amount of common stock or to declare and pay any particular amount of dividends, and the 2023-2024 Stockholder Return Program may be suspended or discontinued at any time at our discretion.

On September 25, 2023, our Board of Directors declared a cash dividend of $0.65 per share on our issued and outstanding common stock, which is payable on December 15, 2023, to stockholders of record as of the close of business on December 1, 2023. As of September 30, 2023, $745 million for dividends payable is presented within Other current liabilities on our Condensed Consolidated Balance Sheets, of which $393 million is payable to DT.

During the three and nine months ended September 30, 2023, we did not repurchase any shares of our common stock under the 2023-2024 Stockholder Return Program. As of September 30, 2023, we had up to $18.3 billion remaining under the 2023-2024 Stockholder Return Program.

Subsequent to September 30, 2023, from October 1, 2023, through October 20, 2023, we repurchased 5,515,568 shares of our common stock at an average price per share of $139.76 for a total purchase price of $771 million. As of October 20, 2023, we had up to $17.5 billion remaining under the 2023-2024 Stockholder Return Program.

Discontinued Operations and Disposal Groups [Abstract]

Wireline

Note 11 – Wireline

Sale of the Wireline Business

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

On May 1, 2023, pursuant to the Wireline Sale Agreement, upon the terms and subject to the conditions thereof, we completed the Wireline Transaction. Under the terms of the Wireline Sale Agreement, the parties agreed to a $1 purchase price in consideration for the Purchased Interests, subject to customary adjustments, as well as payments to the Buyer pursuant to an IP transit services agreement totaling $700 million, consisting of (i) $350 million in equal monthly installments during the first year after the Closing and (ii) $350 million in equal monthly installments over the subsequent 42 months. The Buyer paid the

Company $61 million at Closing. The Closing of the Wireline Transaction did not have a significant impact on the Loss (gain) on disposal group held for sale on our Condensed Consolidated Statements of Comprehensive Income.

The present value of the $700 million liability for fees payable for IP transit services was recognized and treated as part of the consideration exchanged with the Buyer to complete the disposal transaction, as there is a remote likelihood we will use any more than a de minimis amount of the services under the IP transit services agreement. Therefore, we concluded the cash payment obligations under the IP transit services agreement were part of the consideration paid to the Buyer to facilitate the sale of the Wireline Business, and therefore, included in measuring the fair value less costs to sell of the Wireline Business disposal group. As of September 30, 2023, $246 million and $275 million of this liability, including accrued interest, is presented within Other current liabilities and Other long-term liabilities, respectively, on our Condensed Consolidated Balance Sheets in accordance with the expected timing of the related payments. As of September 30, 2023, $30 million and $31 million for contractual and other payments associated with the Wireline Transaction are presented within Other current liabilities and Other long-term liabilities, respectively, on our Condensed Consolidated Balance Sheets in accordance with the expected timing of the related payments.

We recognized a pre-tax gain of $25 million during the nine months ended September 30, 2023, and a pre-tax loss of $1.1 billion during the three and nine months ended September 30, 2022, which are included within Loss (gain) on disposal group held for sale on our Condensed Consolidated Statements of Comprehensive Income. There was no gain or loss on disposal group held for sale for the three months ended September 30, 2023.

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

2022 Wireline Impairment

During the second quarter of 2022, we determined that the retirement of the legacy Sprint CDMA and LTE wireless networks triggered the need to assess the Wireline long-lived assets for impairment, as these assets no longer support our wireless network and the associated customers and cash flows in a significant manner. The results of this assessment indicated that certain Wireline long-lived assets were impaired, and as a result, we recorded noncash impairment expense of $477 million during the nine months ended September 30, 2022, all of which relates to the impairment recognized during the three months ended June 30, 2022, of which $258 million was related to Wireline Property and equipment, $212 million was related to Operating lease right-of-use assets and $7 million was related to Other intangible assets. The expense is included within Impairment expense on our Condensed Consolidated Statements of Comprehensive Income. There was no impairment expense recognized for the three and nine months ended September 30, 2023.

(1)     Represents the weighted-average SoftBank Specified Shares Amount that is contingently issuable from the Merger date of April 1, 2020, pursuant to a letter agreement dated February 20, 2020, between T-Mobile, SoftBank and DT (the “Letter Agreement”).

As of September 30, 2023, we had authorized 100 million shares of preferred stock, with a par value of $0.00001 per share. There was no preferred stock outstanding as of September 30, 2023 and 2022. Potentially dilutive securities were not included in the computation of diluted earnings per share if to do so would have been anti-dilutive.

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

The issuance of the SoftBank Specified Shares Amount is contingent on the trailing 45-trading-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 (the “Threshold Price”), at any time during the period commencing on April 1, 2022, and ending on December 31, 2025 (the “Measurement Period”). In accordance with the terms of the Letter Agreement, the Threshold Price is subject to downward adjustment by the per share amount of any cash dividends or other cash distributions declared or paid on our common stock during the Measurement Period. As of September 30, 2023, the Threshold Price is $149.35 and will automatically further adjust upon the declaration of any future cash dividends as provided in the Letter Agreement.

Commitments and Contingencies

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies

Note 13 – Commitments and Contingencies

Purchase Commitments

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

Our purchase commitments are approximately $4.7 billion for the 12-month period ending September 30, 2024, $4.3 billion in total for both of the 12-month periods ending September 30, 2025 and 2026, $2.7 billion in total for both of the 12-month periods ending September 30, 2027 and 2028, and $2.3 billion in total thereafter. These amounts are not reflective of our entire anticipated purchases under the related agreements but are determined based on the non-cancelable quantities or termination amounts to which we are contractually obligated.

On March 9, 2023, we entered into a Merger and Unit Purchase Agreement for the acquisition of 100% of the outstanding equity of Ka’ena Corporation and its subsidiaries including, among others, Mint Mobile LLC, for a maximum purchase price of $1.35 billion to be paid out 39% in cash and 61% in shares of T-Mobile common stock. Our estimate of the upfront payment is subject to Ka’ena Corporation’s underlying business performance and the timing of transaction close, and has been updated to $1.2 billion, before working capital adjustments. The agreement remains subject to regulatory approval, and the estimated purchase price is excluded from our reported purchase commitments above. See Note 2 – Business Combination for additional details.

Spectrum Leases

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

Our spectrum lease and service credit commitments, including renewal periods, are approximately $303 million for the 12-month period ending September 30, 2024, $602 million in total for both of the 12-month periods ending September 30, 2025 and 2026, $666 million in total for both of the 12-month periods ending September 30, 2027 and 2028, and $4.4 billion in total thereafter.

On August 8, 2022, we entered into License Purchase Agreements to acquire spectrum in the 600 MHz band from Channel 51 License Co LLC and LB License Co, LLC in exchange for total cash consideration of $3.5 billion. The licenses are currently being utilized by us through exclusive leasing arrangements with the Sellers. On March 30, 2023, we and the Sellers entered into Amended and Restated License Purchase Agreements pursuant to which we and the Sellers agreed to separate the transaction into two tranches of licenses, with the closings on the acquisitions of certain licenses in Chicago, Dallas and New Orleans being deferred in order to potentially expedite the regulatory approval process for the remainder of the licenses. Subsequently, on August 25, 2023, we and the Sellers entered into Amendments No. 1 to the Amended and Restated License Purchase Agreements, which deferred the closings of certain additional licenses in Chicago and Dallas into the second closing

tranche. Together, the licenses with closings deferred into the second closing tranche represent approximately $1.1 billion of the aggregate $3.5 billion cash consideration. The agreements remain subject to regulatory approval and are excluded from our reported purchase commitments above. See Note 5 – Spectrum License Transactions for additional details.

On September 12, 2023, we entered into a License Purchase Agreement with Comcast pursuant to which we will acquire spectrum in the 600 MHz band from Comcast in exchange for total cash consideration of between $1.2 billion and $3.3 billion, subject to an application for FCC approval. The licenses are subject to an exclusive leasing arrangement between us and Comcast entered into contemporaneously with the License Purchase Agreement. The agreement remains subject to regulatory approval and is excluded from our reported purchase commitments above. See Note 5 – Spectrum License Transactions for additional details.

Merger Commitments

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

Contingencies and Litigation

Litigation and Regulatory Matters

We are involved in various lawsuits and disputes, claims, government agency investigations and enforcement actions, and other proceedings (“Litigation and Regulatory Matters”) that arise in the ordinary course of business, which include claims of patent infringement (most of which are asserted by non-practicing entities primarily seeking monetary damages), class actions, and proceedings to enforce FCC or other government agency rules and regulations. Those Litigation and Regulatory Matters are at various stages, and some of them may proceed to trial, arbitration, hearing, or other adjudication that could result in fines, penalties, or awards of monetary or injunctive relief in the coming 12 months if they are not otherwise resolved. We have established an accrual with respect to certain of these matters, where appropriate. The accruals are reflected on our condensed consolidated financial statements, but they are not considered to be, individually or in the aggregate, material. An accrual is established when we believe it is both probable that a loss has been incurred and an amount can be reasonably estimated. For other matters, where we have not determined that a loss is probable or because the amount of loss cannot be reasonably estimated, we have not recorded an accrual due to various factors typical in contested proceedings, including, but not limited to, uncertainty concerning legal theories and their resolution by courts or regulators, uncertain damage theories and demands, and a less than fully developed factual record. For Litigation and Regulatory Matters that may result in a contingent gain, we recognize such gains on our 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 or other matters that we are or may become involved in could have a material adverse impact on results of operations or cash flows for a particular period. This assessment is based on our current understanding of relevant facts and circumstances. As such, our view of these matters is subject to inherent uncertainties and may change in the future.

On February 28, 2020, we received a Notice of Apparent Liability for Forfeiture and Admonishment from the FCC, which proposed a penalty against us for allegedly violating section 222 of the Communications Act and the FCC’s regulations governing the privacy of customer information. In the first quarter of 2020, we recorded an accrual for an estimated payment amount. We maintained the accrual as of September 30, 2023, and that accrual was included in Accounts payable and accrued liabilities on our Condensed Consolidated Balance Sheets.

On April 1, 2020, in connection with the closing of the Merger, we assumed the contingencies and litigation matters of Sprint.

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

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

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

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

As a result of the August 2021 cyberattack, we have become subject to numerous lawsuits, including mass arbitration claims and multiple class action lawsuits that have been filed in numerous jurisdictions seeking, among other things, unspecified monetary damages, costs and attorneys’ fees arising out of the August 2021 cyberattack. In December 2021, the Judicial Panel on Multidistrict Litigation consolidated the federal class action lawsuits in the U.S. District Court for the Western District of Missouri under the caption In re: T-Mobile Customer Data Security Breach Litigation, Case No. 21-md-3019-BCW. On July 22, 2022, we entered into an agreement to settle the lawsuit. On June 29, 2023, the Court issued an order granting final approval of the settlement, which is subject to potential appeals. Under the terms of the settlement, we would pay an aggregate of $350 million to fund claims submitted by class members, the legal fees of plaintiffs’ counsel and the costs of administering the settlement. We would also commit to an aggregate incremental spend of $150 million for data security and related technology in 2022 and 2023. We previously paid $35 million for claims administration purposes. On July 31, 2023, a class member filed an appeal to the final approval order challenging the Court’s award of attorneys’ fees to class counsel. We expect the remaining portion of the $350 million settlement payment to fund claims to be made once that appeal is resolved. We anticipate that, upon exhaustion of any appeals, the settlement will provide a full release of all claims arising out of the August 2021 cyberattack by class members who do not opt out, against all defendants, including us, our subsidiaries and affiliates, and our directors and officers. The settlement contains no admission of liability, wrongdoing or responsibility by any of the defendants. We have the right to terminate the settlement agreement under certain conditions.

We anticipate that this settlement of the class action, along with other settlements of separate consumer claims that have been previously completed or are currently pending, will resolve substantially all of the claims brought to date by our current, former and prospective customers who were impacted by the 2021 cyberattack. In connection with the proposed class action settlement and the separate settlements, we recorded a total pre-tax charge of approximately $400 million in the second quarter of 2022. During each of the nine months ended September 30, 2023 and 2022, we recognized $50 million in reimbursements from insurance carriers for costs incurred related to the August 2021 cyberattack, which is included as a reduction to Selling, general and administrative expenses on our Condensed Consolidated Statements of Comprehensive Income. The ultimate resolution of the class action depends on the number of plaintiffs who opt-out of the proposed settlement and whether the proposed settlement will be appealed.

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

We have also received inquiries from various government agencies, law enforcement and other governmental authorities related to the August 2021 cyberattack which could result in substantial fines or penalties. We are cooperating fully with these agencies and regulators and working with them to resolve these matters. While we hope to resolve them in the near term, we cannot predict the timing or outcome of any of these matters, or whether we may be subject to further regulatory inquiries, investigations, or enforcement actions.

In light of the inherent uncertainties involved in such matters and based on the information currently available to us, in addition to the previously recorded pre-tax charge of approximately $400 million noted above, we believe it is reasonably possible that we could incur additional losses associated with these proceedings and inquiries, and we will continue to evaluate information as it becomes known and will record an estimate for losses at the time or times when it is both probable that a loss has been incurred and the amount of the loss is reasonably estimable. Ongoing legal and other costs related to these proceedings and inquiries, as well as any potential future actions, may be substantial, and losses associated with any adverse judgments, settlements, penalties or other resolutions of such proceedings and inquiries could be material to our business, reputation, financial condition, cash flows and operating results.

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

On January 5, 2023, we identified that a bad actor was obtaining data through a single Application Programming Interface (“API”) without authorization. Based on our investigation, the impacted API is only able to provide a limited set of customer account data, including name, billing address, email, phone number, date of birth, T-Mobile account number and information such as the number of lines on the account and plan features. The result from our investigation indicates that the bad actor(s) obtained data from this API for approximately 37 million current postpaid and prepaid customer accounts, though many of these accounts did not include the full data set. We believe that the bad actor first retrieved data through the impacted API starting on or around November 25, 2022. We have notified individuals whose information was impacted consistent with state and federal requirements.

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

Restructuring and Related Activities [Abstract]

Restructuring Costs

Note 14 – Restructuring Costs

Merger Restructuring Initiatives

Upon close of the Merger in April 2020, we began implementing restructuring initiatives to realize cost efficiencies and reduce redundancies. The major activities associated with the Merger restructuring initiatives to date include contract termination costs associated with the rationalization of retail stores, distribution channels, duplicative network and backhaul services and other agreements, severance costs associated with the integration of redundant processes and functions and the decommissioning of certain small cell sites and distributed antenna systems to achieve Merger synergies in network costs.

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

(in millions)	Three Months Ended September 30, 2023		Nine Months Ended September 30, 2023		Incurred to Date
Contract termination costs	$	7	$	31	$	454
Severance costs	—		3		574
Network decommissioning	52		223		1,700
Total restructuring plan expenses	$	59	$	257	$	2,728

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

Our Merger restructuring initiatives also include the acceleration or termination of certain of our operating and financing leases for cell sites, switch sites, retail stores, network equipment and office facilities. Incremental expenses associated with accelerating amortization of the right-of-use assets on lease contracts were $67 million and $384 million for the three months ended September 30, 2023 and 2022, respectively, and $303 million and $1.6 billion for the nine months ended September 30, 2023 and 2022, respectively, and are included in Costs of services and Selling, general and administrative expenses on our Condensed Consolidated Statements of Comprehensive Income.

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

(in millions)	December 31, 2022		Expenses Incurred		Cash Payments		Adjustments for Non-Cash Items (1)		September 30, 2023
Contract termination costs	$	190	$	31	$	(199)	$	—	$	22
Severance costs	—		3		(6)		3		—

Total	$	470	$	257	$	(549)	$	(12)	$	166

(1)    Non-cash items primarily consist of the write-off of assets within Network decommissioning.

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

We expect to incur substantially all remaining costs associated with our Merger restructuring activities by the end of this year, with the related cash outflows extending beyond 2023.

2023 Workforce Reduction

In August 2023, we began implementing an initiative to reduce the size of our workforce by approximately 5,000 positions, just under 7% of our total employee base, primarily in corporate and back-office functions, and some technology roles. We recorded a pre-tax charge of $471 million during the three months ended September 30, 2023, related to the workforce reduction, which is included in Costs of services and Selling, general and administrative expenses on our Condensed Consolidated Statements of Comprehensive Income.

The changes in the liabilities associated with our workforce reduction initiative, including expenses incurred and cash payments, are as follows:

(in millions)	December 31, 2022		Expenses Incurred		Cash Payments		Other (1)		September 30, 2023
Severance costs	$	—	$	471	$	(18)	$	14	$	467

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Consolidation

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, 2022.

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. Estimates are inherently subject to judgment and actual results could differ from those estimates.

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

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

Dividends

Dividends

On September 6, 2023, our Board of Directors authorized a stockholder return program of up to $19.0 billion that will run through December 31, 2024 (the “2023-2024 Stockholder Return Program”). The 2023-2024 Stockholder Return Program is expected to consist of additional repurchases of shares of our common stock and the payment of cash dividends. The amount available under the 2023-2024 Stockholder Return Program for share repurchases will be reduced by the amount of any cash dividends declared by us.

Dividends declared are included as a reduction to Retained earnings on our Condensed Consolidated Balance Sheets. We recognize a liability for dividends declared but for which cash has not been paid in Other current liabilities on our Condensed Consolidated Balance Sheets. Dividend cash payments to stockholders will be included in Net cash (used in) provided by financing activities on our Condensed Consolidated Statements of Cash Flows.

Accounting Pronouncements Adopted During the Current Year

Accounting Pronouncements Adopted During the Current Year

Troubled Debt Restructurings and Vintage Disclosures

In March 2022, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2022-02, “Financial Instruments—Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures.” The standard eliminates the accounting guidance within ASC 310-40 for troubled debt restructurings by creditors while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty. Additionally, for public business entities, the standard requires disclosure of current-period gross write-offs by year of origination for financing receivables and net investments in leases within the scope of ASC 326-20. As of January 1, 2023, we have adopted this standard, and it was applied prospectively after this date. This standard did not have a material impact on our condensed consolidated financial statements as of and for the three and nine months ended September 30, 2023.
