▪ Branded postpaid net customer additions were 4,515,000 in 2019, compared to 4,459,000 in 2018. Full-year 2019 branded postpaid net customer additions exceeded the top end of the revised and increased guidance range of 4.1 to 4.3 million provided in connection with Q3 2019 earnings.

▪ Branded postpaid phone churn was 0.89% in2019, down 12 basis points compared to 1.01% in 2018 primarily from increased customer satisfaction and loyalty from ongoing improvements to network quality, industry-leading customer service and the overall value of our offerings.

Branded Prepaid Customers

▪ Branded prepaid net customer additions were 77,000 in Q4 2019, compared to 62,000 in Q3 2019 and 135,000 in Q4 2018.

▪ Sequentially, the increase was primarily due to the continued success of our prepaid brands due to seasonality, promotional activities and rate plan offers, partially offset by higher migrations to postpaid plans.

▪ Year-over-year, the decrease was primarily due to the impact of continued competitor promotional activities in the marketplace.

▪ Migrations to branded postpaid plans reduced branded prepaid net customer additions in Q4 2019 by approximately 160,000, up from 130,000 in Q3 2019 and flat from 160,000 in Q4 2018.

▪ On July 18, 2019, we entered into an agreement whereby certain T-Mobile branded prepaid products will now be offered and distributed by a current Mobile Virtual Network Operator (“MVNO”) partner. Upon the effective date, the agreement resulted in a base adjustment to reduce branded prepaid customers by 616,000 as we will no longer actively support the branded product offering. Prospectively, new customer activity associated with these products is recorded within Wholesale customers and revenue for these customers is recorded within Wholesale revenues in our Consolidated Statements of Comprehensive Income.

T-Mobile 5G Coverage Map

(as of December 31, 2019)

NETWORK

5G

▪ On December 2, 2019, T-Mobile launched America’s first nationwide 5G network, including prepaid 5G with Metro by T-Mobile, covering more than 200 million people and more than 5,000 cities and towns across over 1 million square miles with 5G. In addition, we introduced two new 600 MHz 5G capable superphones, the exclusive OnePlus 7T Pro 5G McLaren and the Samsung Galaxy Note10+ 5G and anticipate offering an industry-leading smartphone portfolio built to work on nationwide 5G in 2020. This 5G network is our foundational layer of 5G coverage on 600 MHz low-band spectrum.

▪ Should we close our merger with Sprint, we will rapidly deploy 5G on Sprint’s 2.5 GHz spectrum, completing the “layer cake” of spectrum and providing consumers with an unmatched 5G experience.

▪ On June 28, 2019, T-Mobile introduced its 5G network using high-band millimeter wave (mmWave) spectrum in conjunction with the introduction of our first 5G handset, the Samsung Galaxy S10 5G. The 5G network on mmWave spectrum has been rolled out in parts of seven cities (New York City, Los Angeles, Dallas, Atlanta, Cleveland, Las Vegas and Miami).

600 MHz Spectrum

▪ At the end of Q4 2019, T-Mobile owned a nationwide average of 31 MHz of 600 MHz low-band spectrum. In total, T-Mobile owns approximately 41 MHz of low-band spectrum (600 MHz and 700 MHz). The spectrum covers 100% of the U.S.

▪ As of the end of Q4 2019, T-Mobile had cleared 275 million POPs and expects to clear the remaining 600 MHz spectrum POPs in 2020.

▪ T-Mobile continues its deployment of LTE on 600 MHz spectrum using 5G-ready equipment. At the end of Q4 2019, we were live with 4G LTE in nearly 8,900 cities and towns in 49 states and Puerto Rico covering 1.5 million square miles and 248 million POPs.

▪ Combining 600 and 700 MHz spectrum, we have deployed 4G LTE in low-band spectrum to 316 million POPs.

▪ Currently, more than 33 million devices on T-Mobile’s network are compatible with 600 MHz spectrum.

Depth of T-Mobile’s Nationwide mmWave Spectrum

Spectrum Position

▪ At the end of Q4 2019, T-Mobile owned an average of 111 MHz of spectrum nationwide, not including mmWave spectrum. The spectrum comprises an average of 31 MHz in the 600 MHz band, 10 MHz in the 700 MHz band, 29 MHz in the 1900 MHz PCS band, and 41 MHz in the AWS band.

▪ On June 3, 2019, the FCC announced the results of Auctions 101 (28 GHz spectrum) and 102 (24 GHz spectrum). In the combined auctions, T-Mobile spent $842 million to more than quadruple its nationwide average total mmWave spectrum holdings from 104 MHz to 471 MHz.

▪ We will evaluate future spectrum purchases in upcoming auctions and in the secondary market to further augment our current spectrum position. We are not aware of any such spectrum purchase options that come close to matching the efficiencies and synergies possible from merging with Sprint.

Network Coverage Growth

▪ T-Mobile continues to expand its coverage breadth and covered 327 million people with 4G LTE at the end of Q4 2019.

▪ At the end of Q4 2019, T-Mobile had equipment deployed on approximately 66,000 macro cell sites and 25,000 small cell/distributed antenna system sites.

Network Capacity Growth

▪ Due to industry spectrum limitations (especially in mid-band), T-Mobile continues to make efforts to expand its capacity and increase the quality of its network through the re-farming of existing spectrum and implementation of new technologies including Voice over LTE (“VoLTE”), Carrier Aggregation, 4x4 multiple-input and multiple-output (“MIMO”), 256 Quadrature Amplitude Modulation (“QAM”) and License Assisted Access (“LAA”).

▪ VoLTE comprised 90% of total voice calls in Q4 2019, flat with 90% in Q3 2019 and up from 87% in Q4 2018.

▪ Carrier aggregation is live for T-Mobile customers in 969 markets, up from 956 markets in Q3 2019 and 923 in Q4 2018.

▪ 4x4 MIMO is currently available in 708 markets, up from 683 markets in Q3 2019 and 564 in Q4 2018.

▪ T-Mobile customers have 256 QAM available across the Un-carrier’s entire 4G LTE footprint.

PROPOSED SPRINT TRANSACTIONS

▪ On April 29, 2018, T-Mobile entered into a Business Combination Agreement with Sprint to merge in an all-stock transaction at a fixed exchange ratio of 0.10256 shares of T-Mobile common stock for each share of Sprint common stock, or 9.75 shares of Sprint common stock for each share of T-Mobile common stock (the “Merger”). The Merger, and other transactions contemplated by the Business Combination Agreement, are referred to as the “Transactions.”

▪ The combined company will be named “T-Mobile” and, as a result of the Merger, is expected to be able to build upon our recently launched foundational 5G network of 600 MHz spectrum to deliver transformational broad and deep 5G with crazy-fast speeds for customers nationwide, accelerate innovation and supercharge competition in the U.S. wireless, video and broadband industries. With real, nationwide 5G for All, the New T-Mobile will open massive wireless highways and lower prices for all Americans, helping to ignite innovation and challenge a failed status quo. Neither T-Mobile nor Sprint on its own could generate comparable benefits to consumers. The combined company is expected to trade under the “TMUS” symbol on NASDAQ.

▪ The Transactions are subject to certain closing conditions:

▪ We received approval from CFIUS and Team Telecom in December 2018.

▪ We received favorable action from 18 of the 19 state utility commissions conducting reviews with only the California Public Utility Commission (PUC) still outstanding.

▪ In June 2019, a number of state attorneys general filed a lawsuit against us, Deutsche Telekom, Sprint, and SoftBank in the U.S. District Court for the Southern District of New York, alleging that the Merger, if consummated, would violate Section 7 of the Clayton Act and so should be enjoined. We believe the plaintiffs’ claims are without merit, and have defended the case vigorously. The trial concluded and we are now waiting for the trial court’s ruling.

▪ In July 2019, T-Mobile and Sprint received clearance for the Merger from the U.S. Department of Justice by entering into a consent decree. The DOJ consent decree is still subject to the final Tunney Act review, which is expected to conclude in February 2020.

10

▪ In July 2019, T-Mobile and Sprint also entered into agreements with DISH Network Corporation to divest Sprint’s prepaid businesses and 800 MHz spectrum assets to DISH for total proceeds of $5.0 billion. Additionally, the companies will enter into commercial agreements to provide the transferred prepaid and new DISH wireless customers access to the New T-Mobile network for seven years.

▪ The Federal Communications Commission (“FCC”) approved the Merger on November 5, 2019.

▪ We remain confident about completing the final steps for the Merger.

▪ We expect the Merger will be permitted to close in early 2020.

▪ In Q4 2019, costs related to the Sprint transaction were $126 million before taxes compared to $159 million in Q3 2019 and $102 million in Q4 2018. These costs impacted Selling, general, and administrative (“SG&A”) expenses and Net income but are excluded from Adjusted EBITDA.

▪ In Q1 2020, pre-close merger-related costs are expected to be $200 million to $300 million before taxes.

CUSTOMER QUALITY

▪ Total bad debt expense and losses from sales of receivables was $128 million in Q4 2019, compared to $102 million in Q3 2019 and $118 million in Q4 2018.

▪ As a percentage of total revenues, total bad debt expense and losses from sales of receivables was 1.07% in Q4 2019, compared to 0.92% in Q3 2019 and 1.03% in Q4 2018.

▪ Sequentially, total bad debt expense and losses from sales of receivables increased by $26 million. As a percentage of Total revenues, bad debt expense and losses from sales of receivables increased by 15 basis points. These increases were primarily driven by seasonality and certain one-time benefits which occurred in Q3 2019.

▪ Year-over-year, total bad debt expense and losses from sales of receivables increased by $10 million. As a percentage of Total revenues, bad debt expense and losses from sales of receivables increased by 4 basis points.

▪ For full-year 2019, total bad debt expense and losses from sales of receivables decreased to $437 million from $454 million in 2018. As a percentage of Total revenues, total bad debt expense and losses from sales of receivables was 0.97% in 2019 compared to 1.05% in 2018.

Branded Postpaid Phone ARPU

($ per month)

OPERATING METRICS

Branded Postpaid Phone ARPU

▪ Branded postpaid phone ARPU was $45.79 in Q4 2019, down 0.9% from $46.22 in Q3 2019 and down 1.1% from $46.29 in Q4 2018.

▪ Sequentially, the decrease was primarily due to dilution from promotional activities and a reduction in the non-cash, non-recurring benefit related to Data Stash, as the majority of impacted customers had transitioned to unlimited plans by Q3 2019, partially offset by the growing success of new customer segments and rate plans.

▪ Year-over-year, the decrease was primarily due to dilution from promotional activities, a reduction in regulatory program revenues from the continued adoption of tax inclusive plans and a reduction in the non-cash, non-recurring benefit related to Data Stash as the majority of impacted customers had transitioned to unlimited plans by Q3 2019, partially offset by the growing success of new customer segments and rate plans and higher premium services revenue.

▪ For full-year 2019, branded postpaid phone ARPU was $46.04, down 0.8% from $46.40 in 2018, primarily from an increase in promotional activities, including the ongoing growth in our Netflix offering, which totaled $0.54 for 2019, and decreased branded postpaid phone ARPU by $0.19 compared to 2018, a reduction in regulatory program revenues from the continued adoption of tax inclusive plans and a reduction in certain non-recurring charges, partially offset by higher premium services revenue and the growing success of new customer segments and rate plans.

▪ We expect Branded postpaid phone ARPU in full-year 2020 to be generally stable compared to full-year 2019 within a range of plus 1% to minus 1%.

▪ Starting in Q1 2020, we plan to report Average Revenue per Postpaid Account or Postpaid ARPA in addition to our existing ARPU metrics, reflecting the increasing importance of non-phone devices to our customers. We also plan to discontinue reporting branded postpaid customers per account.

▪ The sequential and year-over-year increases were primarily due to the continued growth of new customer segments and rate plans such as Unlimited 55+, Military, Business and Essentials, promotional activities targeting families and the continued success of other connected devices and wearables, specifically the Apple Watch.

Branded Prepaid ARPU

▪ Branded prepaid ARPU was $38.54 in Q4 2019, up 1.0% from $38.16 in Q3 2019 and essentially flat compared to $38.39 in Q4 2018.

▪ Sequentially, the increase was primarily due to certain one-time tax benefits and the removal of certain branded prepaid customers associated with products now offered and distributed by a current MVNO partner as those customers had lower ARPU, partially offset by dilution from promotional activity.

▪ Year-over-year, the slight increase was primarily due to a combination of offsetting factors including the removal of certain branded prepaid customers associated with products now offered and distributed by a current MVNO partner as those customers had lower ARPU and certain one-time tax benefits, offset by dilution from promotional activity, a reduction in certain one-time charges, and the growth in our Amazon Prime offering - included as a benefit with certain Metro by T-Mobile unlimited rate plans as of Q4 2018 - which impacted branded prepaid ARPU by $0.39 in Q4 2019 and decreased branded prepaid ARPU by $0.27 compared to Q4 2018.

▪ For full-year 2019, branded prepaid ARPU was $37.95, down 1.5% compared to $38.53 in 2018, primarily from dilution from promotional activity and the growth in our Amazon Prime offering - included as a benefit with certain Metro by T-Mobile unlimited rate plans as of Q4 2018 - which impacted branded prepaid ARPU by $0.39 in 2019 and decreased branded prepaid ARPU by $0.36 compared to 2018, partially offset by the removal of certain branded prepaid customers associated with products now offered and distributed by a current MVNO partner as those customers had lower ARPU.

▪ Our 2020 guidance outlook is for T-Mobile standalone.

▪ Branded postpaid net customer additions: Branded postpaid net customer additions for the full-year 2020 are expected to be 2.6 to 3.6 million.

▪ Net Income: We are not able to forecast Net income on a forward-looking basis without unreasonable efforts due to the high variability and difficulty in predicting certain items that affect GAAP Net income, including, but not limited to, Income tax expense, stock-based compensation expense and Interest expense. Adjusted EBITDA should not be used to predict Net income as the difference between the two measures is variable.

▪ Adjusted EBITDA: For the full-year 2020, Adjusted EBITDA is expected to be in the range of $13.7 to $14.0 billion. This target includes expected leasing revenues of $450 to $550 million and takes into account the network expansion, including the continued deployment of our 600 MHz spectrum and 5G network.

We expect that cash purchases of property and equipment will be heavily weighted to early in the year, similar to 2019.

▪ Net cash provided by operating activities:Net cash provided by operating activities, excluding payments for merger-related costs and any settlement of interest rate swaps, is expected to be in the range of $7.9 to $8.5 billion in 2020.

▪ Free Cash Flow: Free Cash Flow, excluding payments for merger-related costs and any settlement of interest rate swaps, is expected to be in the range of $5.4 to $5.8 billion in 2020. We expect a similar seasonal development of Free Cash Flow in 2020 as in 2019 with a lower Free Cash Flow in the first quarter, ramping in later quarters, based on expected timing for cash purchases of property and equipment. Free cash flow guidance does not assume any material net cash inflows from securitization in 2020.

▪ Branded postpaid phone ARPU:We expect Branded postpaid phone ARPU in full-year 2020 to be generally stable compared to full-year 2019 within a range of plus 1% to minus 1%.

▪ Tax Rate:For full-year 2020, the effective tax rate is expected to be 26% to 27%.

▪ Merger-related costs:In Q1 2020, pre-close merger-related costs are expected to be$200 to $300 million before taxes. These costs are excluded from Adjusted EBITDA but will impact Net income and cash flows.

UPCOMING EVENTS (All dates and attendance tentative)

▪ Morgan Stanley Technology, Media & Telecom Conference, March 2-5, San Francisco, CA

▪ Deutsche Bank 28th Annual Media, Internet & Telecom Conference, March 9-11, Palm Beach, FL

Reconciliation of Non-GAAP Financial Measures to GAAP Financial Measures

(Unaudited)

This Investor Factbook includes non-GAAP financial measures. The non-GAAP financial measures should be considered in addition to, but not as a substitute for, the information provided in accordance with GAAP. Reconciliations for the non-GAAP financial measures to the most directly comparable GAAP financial measures are provided below. T-Mobile is not able to forecast net income on a forward-looking basis without unreasonable efforts due to the high variability and difficulty in predicting certain items that affect GAAP net income including, but not limited to, income tax expense, stock-based compensation expense and interest expense. Adjusted EBITDA should not be used to predict net income as the difference between the two measures is variable.

Adjusted EBITDA is reconciled to net income as follows:

(1) Stock-based compensation includes payroll tax impacts and may not agree to stock-based compensation expense in the Consolidated Financial Statements. Additionally, certain stock-based compensation expenses associated with the Transactions have been included in Merger-related costs.

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

(1) In Q1 2019, the adoption of the new lease accounting standard resulted in a reclassification of capital lease liabilities previously included in Short-term debt and Long-term debt to Short-term financing lease liabilities and Financing lease liabilities in our Consolidated Balance Sheet. In Q1 2019, we redefined Net debt (excluding tower obligations) to reflect the above changes in classification and present Net debt (excluding tower obligations) on a consistent basis for investor transparency. The effects of this change are applied prospectively, consistent with the adoption of the standard.

Definitions of Terms

Operating and financial measures are utilized by T-Mobile’s management to evaluate its operating performance and, in certain cases, its ability to meet liquidity requirements. Although companies in the wireless industry may not define measures in precisely the same way, T-Mobile believes the measures facilitate key operating performance comparisons with other companies in the wireless industry to provide management, investors and analysts with useful information to assess and evaluate past performance and assist in forecasting future performance.

1. Customer - SIM number with a unique T-Mobile mobile identifier which is associated with an account that generates revenue. Branded customers generally include customers that are qualified either for postpaid service, where they generally pay after incurring service, or prepaid service, where they generally pay in advance. Wholesale customers include Machine-to-Machine (M2M) and Mobile Virtual Network Operator (MVNO) customers that operate on T-Mobile’s network, but are managed by wholesale partners.

2. Churn - Number of customers whose service was disconnected as a percentage of the average number of customers during the specified period. The number of customers whose service was disconnected is presented net of customers that subsequently have their service restored within a certain period of time.

3. Customers per account - The number of branded postpaid customers as of the end of the period divided by the number of branded postpaid accounts as of the end of the period. An account may include branded postpaid phone, mobile broadband, and DIGITS customers.

4. Average Revenue Per User (ARPU) - Average monthly service revenue earned from customers. Service revenues for the specified period divided by the average customers during the period, further divided by the number of months in the period.

Branded postpaid phone ARPU excludes branded postpaid other customers and related revenues.

Service revenues - Branded postpaid, including handset insurance, branded prepaid, wholesale, and roaming and other service revenues.

5. Cost of services - Costs directly attributable to providing wireless service through the operation of T-Mobile’s network, including direct switch and cell site costs, such as rent, network access and transport costs, utilities, maintenance, associated labor costs, long distance costs, regulatory program costs, roaming fees paid to other carriers and data content costs.

Cost of equipment sales - Costs of devices and accessories sold to customers and dealers, device costs to fulfill insurance and warranty claims, write-downs of inventory related to shrinkage and obsolescence, and shipping and handling costs.

Selling, general and administrative expenses - Costs not directly attributable to providing wireless service for the operation of sales, customer care and corporate activities. These include all commissions paid to dealers and retail employees for activations and upgrades, labor and facilities costs associated with retail sales force and administrative space, marketing and promotional costs, customer support and billing, bad debt expense and administrative support activities.

6. Net income margin - Margin % calculated as net income divided by service revenues.

7. Adjusted EBITDA - Earnings before interest expense, net of interest income, income tax expense, depreciation and amortization expense, non-cash stock-based compensation and certain expenses not reflective of T-Mobile’s ongoing operating performance such as merger-related costs. Adjusted EBITDA margin represents Adjusted EBITDA divided by service revenues. Adjusted EBITDA is a non-GAAP financial measure utilized by T-Mobile’s management to monitor the financial performance of our operations. T-Mobile uses Adjusted EBITDA internally as a measure to evaluate and compensate its personnel and management for their performance, and as a benchmark to evaluate T-Mobile’s operating performance in comparison to its competitors. Management believes analysts and investors use Adjusted EBITDA as a supplemental measure to evaluate overall operating performance and facilitate comparisons with other wireless communications companies because it is indicative of T-Mobile’s ongoing operating performance and trends by excluding the impact of interest expense from financing, non-cash depreciation and amortization from capital investments, non-cash stock-based compensation, network decommissioning costs and costs related to the Transactions, as they are not indicative of T-Mobile’s ongoing operating performance, as well as certain other nonrecurring income and expenses. Adjusted EBITDA has limitations as an analytical tool and should not be considered in isolation or as a substitute for income from operations, net income or any other measure of financial performance reported in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”).

8. Adjusted EBITDA Margin - Margin % calculated as Adjusted EBITDA divided by service revenues.

9. Smartphones - UMTS/HSPA/HSPA+ 21/HSPA+ 42/4G LTE enabled converged devices, which integrate voice and data services.

10. Free Cash Flow - Net cash provided by operating activities less cash purchases of property and equipment, including proceeds from sales of tower sites and proceeds related to beneficial interests in securitization transactions and less cash payments for debt prepayment or debt extinguishment costs. Free Cash Flow is utilized by T-Mobile’s management, investors, and analysts to evaluate cash available to pay debt and provide further investment in the business. The reconciliation of Free Cash Flow to net cash provided by operating activities is detailed in the Reconciliation of Non-GAAP Financial Measures to GAAP Financial Measures schedule. In Q1 2018, we made an accounting change to reduce net cash provided by operating activities by the deferred purchase price less payments for debt prepayment or debt extinguishment costs, as a result of the adoption of ASU 2016-15. Free Cash Flow has been redefined to reflect the changes in classification and present cash flows on a consistent basis for investor transparency.

11. Net debt - Short-term debt, short-term debt to affiliates, long-term debt, and long-term debt (excluding tower obligations) to affiliates, short-term financing lease liabilities and financing lease liabilities, less cash and cash equivalents. Leases classified as capital leases under the previous standard are included in Financing Lease liabilities within our Consolidated Balance Sheet under the new lease standard. The liabilities related to these leases are included in the Net debt calculation under the previous and new lease standards.

Cautionary Statement Regarding Forward-Looking Statements

This communication includes forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. All statements other than statements of historical fact, including information concerning T-Mobile US, Inc.’s future results of operations, are forward-looking statements. These forward-looking statements are generally identified by the words “anticipate”, “believe”, “estimate”, “expect”, “intend”, “may”, “could” or similar expressions. Forward-looking statements are based on current expectations and assumptions, which are subject to risks and uncertainties and may cause actual results to differ materially from the forward-looking statements. Important factors that could affect future results and cause those results to differ materially from those expressed in the forward-looking statements include, among others, the following: the failure to obtain, or delays in obtaining, regulatory approval for the merger (the “Merger”) with Sprint Corporation (“Sprint”), pursuant to the Business Combination Agreement with Sprint and other parties therein (as amended, the “Business Combination Agreement”) and the other transactions contemplated by the Business Combination Agreement (collectively, the “Transactions”), risks associated with the actions and conditions we have agreed to in connection with regulatory approval for the Transactions, and the risk that such regulatory approval may result in the imposition of additional conditions that, if accepted by the parties, could adversely affect the combined company or the expected benefits of the Transactions, or the failure to satisfy any of the other conditions to the Transactions on a timely basis or at all; the risk that the antitrust litigation related to the Transactions brought by the attorneys general of certain states and the District of Columbia will result in an order preventing the completion of the Transactions and the risk of other litigation or regulatory or regulatory actions related to the Transactions; the exercise by one or both parties of a right to terminate the Business Combination Agreement; adverse effects on the market price of our common stock or on our operating results because of a failure to complete the Merger in the anticipated timeframe, on the anticipated terms or at all; inability to obtain the financing contemplated to be obtained in connection with the Transactions on the expected terms or timing or at all; the ability of us, Sprint and the combined company to make payments on debt or to repay existing or future indebtedness when due or to comply with the covenants contained therein; adverse changes in the ratings of our or Sprint’s debt securities or adverse conditions in the credit markets; negative effects of the announcement, pendency or consummation of the Transactions on the market price of our common stock and on our or Sprint’s operating results, including as a result of changes in key customer, supplier, employee or other business relationships; the assumption of significant liabilities in connection with, and significant costs related to the Transactions, including financing costs and unknown liabilities of Sprint that may become liabilities of the combined company or that may otherwise arise and financing costs; failure to realize the expected benefits and synergies of the Transactions in the expected timeframes, in part or at all; costs or difficulties related to the integration of Sprint’s network and operations into our network and operations, including intellectual property and communications systems, administrative and information technology infrastructure and accounting, financial reporting and internal control systems; differences with Sprint’s control environments, cultures, and auditor expectations may result in future material weaknesses, significant deficiencies, and/or control deficiencies while we work to integrate the companies and align guidelines and practices; costs or difficulties related to the completion of the divestiture of Sprint’s prepaid wireless businesses to DISH Network Corporation and the satisfaction of any related government commitments to such divestiture; the inability of us, Sprint or the combined company to retain and hire key personnel; the risk that certain contractual restrictions contained in the Business Combination Agreement during the pendency of the Transactions could adversely affect our or Sprint’s ability to pursue business opportunities or strategic transactions; adverse economic, political or market conditions in the U.S. and international markets; competition, industry consolidation, and changes in the market for wireless services, which could negatively affect our ability to attract and retain customers; the effects of any future merger, investment, or acquisition involving us, as well as the effects of mergers, investments, or acquisitions in the technology, media and telecommunications industry; challenges in implementing our business strategies or funding our operations, including payment for additional spectrum or network upgrades; the possibility that we may be unable to renew our spectrum licenses on attractive terms or acquire new spectrum licenses at reasonable costs and terms; difficulties in managing growth in wireless data services, including network quality; material changes in available technology and the effects of such changes, including product substitutions and deployment costs and performance; the timing, scope and financial impact of our deployment of advanced network and business technologies; the impact on our networks and business from major technology equipment failures; inability to implement and maintain effective cyber security measures over critical business systems; breaches of our and/or our third-party vendors’ networks, information technology and data security, resulting in unauthorized access to customer confidential information; natural disasters, terrorist attacks or similar incidents; unfavorable outcomes of existing or future litigation; any changes in the regulatory environments in which we operate, including any increase in restrictions on the ability to operate our networks and changes in data privacy laws; any disruption or failure of our third parties’ or key suppliers’ provisioning of products or services; material adverse changes in labor matters, including labor campaigns, negotiations or additional organizing activity, and any resulting financial, operational and/or reputational impact; changes in accounting assumptions that regulatory agencies, including the Securities and Exchange Commission (“SEC”), may require, which could result in an impact on earnings; changes in tax laws, regulations and existing standards and the resolution of disputes with any taxing jurisdictions; the possibility that the reset process under our trademark license results in changes to the royalty rates for our trademarks; the possibility that we may be unable to adequately protect our intellectual property rights or be accused of infringing the intellectual property rights of others; our business, investor confidence in our financial results and stock price may be adversely affected if our internal controls are not effective; the occurrence of high fraud rates related to device financing, credit cards, dealers, or subscriptions;
