T-Mobile USA, Inc.

$2,000,000,000

$                         % Senior Notes due 2022

$                         % Senior Notes due 2024

T-Mobile USA, Inc. (the “Issuer”) is offering $                 aggregate principal amount of its     % Senior Notes due 2022 (the “2022 notes”) and $                     aggregate principal amount of its     % Senior Notes due 2024 (the “2024 notes,” and together with the 2022 notes, the “notes,” and each a “series” of notes).

The 2022 notes will bear interest at a rate of     % per year and mature on January 15, 2022. The 2024 notes will bear interest at a rate of     % per year and mature on January 15, 2024. The Issuer will pay interest on each series of notes on each January 15 and July 15, commencing July 15, 2014.

The notes of each series will be redeemable, in whole or in part, at any time on or after January 15, 2018 (in the case of the 2022 notes) or January 15, 2019 (in the case of the 2024 notes) and at the redemption prices specified under “Description of Notes—Optional Redemption” plus accrued and unpaid interest to, but not including, the redemption date. The Issuer may redeem up to 35% of the aggregate principal amount of each series of notes prior to January 15, 2017 with the net cash proceeds from certain equity offerings. The Issuer also may redeem each series of notes prior to the dates specified under “Description of Notes—Optional Redemption” at a specified “make-whole” redemption price plus accrued and unpaid interest to, but not including, the redemption date.

If the Issuer experiences certain change of control triggering events, the Issuer will be required to offer to repurchase each series of notes at a repurchase price equal to 101% of the principal amount, plus accrued and unpaid interest to, but not including, the repurchase date. See “Description of Notes—Repurchase at the Option of Holders—Change of Control Triggering Event.”

The Issuer’s obligations under the notes will initially be guaranteed by the Issuer’s corporate parent, T-Mobile US, Inc. (“Parent”), and all of the Issuer’s wholly-owned domestic restricted subsidiaries (excluding certain designated special purpose entities, a certain reinsurance subsidiary and immaterial subsidiaries), all of the Issuer’s restricted subsidiaries that guarantee certain of its indebtedness, and any future subsidiary of Parent that directly or indirectly owns any of the Issuer’s equity interests.

The notes and the guarantees will be the Issuer’s and the guarantors’ unsubordinated unsecured obligations and will rank equally in right of payment with all of the Issuer’s and the guarantors’ existing and future indebtedness and other liabilities that are not by their terms subordinated in right of payment to the notes and guarantees, including the Issuer’s existing senior notes, and will rank senior in right of payment to any future indebtedness of the Issuer or any guarantor that provides by its terms that it is subordinated in right of payment to the notes and the guarantees. The notes and the guarantees will be effectively subordinated to all of the Issuer’s and the guarantors’ existing and future secured indebtedness, to the extent of the assets securing such indebtedness, and will be structurally subordinated to all of the liabilities and preferred stock of any of the Issuer’s subsidiaries that do not guarantee the notes.

Investing in the notes involves risks. See “Risk Factors” beginning on page S-16 of this prospectus supplement. You should also consider the risk factors described in the documents incorporated by reference into the accompanying prospectus.

Our company

T-Mobile is a national provider of mobile communications services capable of reaching over 280 million Americans. Our objective is to be the simpler choice for a better mobile experience. Our intent is to bring this proposition to life across all our brands, including T-Mobile, MetroPCS, and GoSmart, and across our major customer base of retail, wholesale and business (B2B) consumers.

We generate revenue by offering affordable postpaid and prepaid wireless voice, messaging and data services, as well as mobile broadband and wholesale wireless services. We provided service to approximately 45 million customers through our nationwide network as of September 30, 2013. We also generate revenues by offering a wide selection of wireless handsets and accessories, including smartphones, wireless-enabled computers such as notebooks and tablets, and data cards which are manufactured by various suppliers. Our most significant expenses are related to acquiring and retaining customers, maintaining and expanding our network, and compensating employees.

Business combination with MetroPCS

On April 30, 2013, the transactions contemplated by the Business Combination Agreement (the “Business Combination Agreement”), dated October 3, 2012, by and among Deutsche Telekom AG (“Deutsche Telekom”), T-Mobile Global Zwischenholding GmbH, a direct wholly-owned subsidiary of Deutsche Telekom (“Global”), T-Mobile Global Holding GmbH, a direct wholly-owned subsidiary of Global (“Holding”), T-Mobile USA, Inc., formerly a direct wholly-owned subsidiary of Holding (“T-Mobile USA”), and T-Mobile US, Inc. (formerly known as MetroPCS Communications, Inc. (“MetroPCS”)) were consummated. We refer to the transactions contemplated by the Business Combination Agreement collectively as the Business Combination Transaction.

Under the terms of the Business Combination Agreement, Deutsche Telekom received approximately 74% of the fully-diluted shares of common stock of the combined company in exchange for its transfer of all of T-Mobile USA’s common stock. This transaction was consummated to provide us with expanded scale, spectrum, and financial resources to compete aggressively with other larger U.S. wireless carriers. The business combination was accounted for as a reverse acquisition with T-Mobile USA as the accounting acquirer. Accordingly, T-Mobile USA’s historical financial statements became the historical financial statements of the combined company.

S-1

Competitive strengths

We believe the following strengths foster our ability to compete against our principal wireless competitors:

• Value leadership in wireless.    We are a leading value-oriented wireless carrier in the United States and the third largest provider of prepaid service plans as measured by subscribers.

• Spectrum assets.    As of September 30, 2013, we hold licenses for wireless spectrum suitable for wireless broadband mobile services (including both HSPA+ and LTE) covering a population of approximately 280 million people in the United States. As of September 30, 2013, we have an average of approximately 74 MHz of spectrum in the top 100 major metropolitan areas and have an average of approximately 77 MHz of spectrum in the top 25 major metropolitan areas. Our aggregate spectrum position is expected to enable contiguous 20x20 MHz channels for LTE deployment in many major metropolitan areas, which is expected to improve capacity to support our product offerings by increasing the data speeds available to our customers.

• Advanced nationwide high-speed network.    As of September 30, 2013, our LTE network covered a population of approximately 200 million people in the United States. We believe the combination of our spectrum position and advanced network technology will provide us with a high-capacity, high-speed network. Upon completion of the migration of the MetroPCS customer base, we expect to have approximately 55,000 equivalent cell sites, including approximately 1,500 MetroPCS macro sites and certain DAS network nodes retained from the MetroPCS network. Approximately 35,000 sites are planned to be enhanced over three years with multi-mode radios, tower-top electronics, and new antennas. This will allow for more robust coverage in buildings and at the edge of coverage areas and will allow for greater data capacity, which we believe will enhance the customer experience for our subscriber base.

• Seasoned executive leadership.    We have a seasoned executive leadership team with significant industry expertise, led by John Legere, our President and Chief Executive Officer. Mr. Legere has over 32 years of experience in the U.S. and global telecommunications and technology industries. J. Braxton Carter, formerly MetroPCS’ Vice Chairman and Chief Financial Officer, serves as our Chief Financial Officer. Our board of directors includes current and former executives of AT&T, Dell, Rockwell International Corporation and Madison Dearborn Partners, LLC, and brings extensive experience in operations, finance, governance and corporate strategy.

Business strategy

We continue to aggressively pursue our strategy to reposition T-Mobile and return the Company to growth. Our strategy focuses on the following elements:

• Un-carrier value proposition.    We plan to extend our position as the leader in delivering distinctive value for consumers in all customer segments. We believe the launches of Un-carrier phases 1 and 2 have been successful, as evidenced by our strong customer growth momentum. Simple Choice plans, launched in March 2013 as phase 1 of our Un-carrier value proposition, eliminate annual service contracts and provide customers with affordable rate plans without the complexity of caps and overage charges. Customers on Simple Choice plans can purchase the most popular smartphones and if qualified, pay for them in affordable interest-free monthly installments. Modernization of the network and introduction of the Apple^® iPhone^®

S-2

in the second quarter of 2013 further repositioned T-Mobile as a provider of dependable high-speed service with a full range of desirable handsets and devices. In July 2013, we announced phase 2 of our Un-carrier value proposition, JUMP!™, which enables participating subscribers to upgrade their eligible handset up to twice a year upon completion of an initial six-month enrollment period. In October 2013, we unveiled phase 3 of our Un-carrier value proposition, which provides our customers reduced United States to International calling rates and roaming fees, and free data roaming while traveling abroad in over 100 countries. In addition, in November 2013, we began to offer the Apple^® iPad^® Air and iPad^® mini.

• Network modernization.    We are currently in the process of rapidly upgrading our network to modernize the 4G network, improve coverage, align spectrum bands with other key players in the U.S. market and deploy nationwide 4G LTE services in 2013. The timing of the launch of 4G LTE allows us to take advantage of the latest and most advanced 4G LTE technology infrastructure, improving the overall capacity and performance of our 4G network, while optimizing spectrum resources. In October 2013, we announced that we have exceeded our 2013 targets for 4G LTE network coverage, by delivering 4G LTE to more than 200 million people in 254 metro areas and a goal to deploy 10+ 10 MHz 4G LTE in 24 of the Top 25 metro areas by year end (and 40 of the Top 50 metro areas). Additionally, the migration of MetroPCS brand legacy CDMA customers onto T-Mobile’s 4G HSPA+ and LTE network is ahead of schedule, providing faster network performance for MetroPCS customers with compatible handsets. We expect the migration to be complete by the end of 2015.

• Multi-segment focus.    We plan to continue to operate in multiple customer market segments to accelerate growth. The addition of the flagship MetroPCS brand to the T-Mobile portfolio increased our ability to serve the full breadth of the wireless market. We expect to continue to accelerate the growth of the MetroPCS brand by expanding into new geographic regions, through the end of 2013 and continuing through 2014. Recently, we introduced the Simple Choice value proposition to our prepaid and B2B customers as well, so that prepaid customers and businesses can leverage the benefits of the Simple Choice plans. Additionally, we expect to continue to expand our wholesale business through MVNOs and other wholesale relationships where our spectrum depth, available network capacity and GSM technology base help secure profitable wholesale customers.

• Aligned cost structure.    We continue to pursue a low-cost business operating model to drive cost savings, which can be reinvested in the business. These cost programs are on-going as we continue to work to simplify our business and drive operational efficiencies and cost savings in areas such as network optimization, customer roaming, customer service, improved customer collection rates and better management of customer acquisition and retention costs. A portion of savings have been, and will continue to be, reinvested into customer acquisition programs.

Recent developments

On October 16, 2013, we completed a secondary public offering of $5.6 billion in aggregate principal amount of senior debt securities of T-Mobile USA and related guarantees previously owned by Deutsche Telekom, pursuant to an underwriting agreement among T-Mobile US, Inc., T-Mobile USA, certain subsidiaries of T-Mobile USA, Deutsche Telekom and Deutsche Bank Securities Inc., as representative of the several underwriters. We did not receive any proceeds from this offering.

S-3

In October 2013, we purchased 10 MHz of AWS spectrum from U.S. Cellular for $308 million in cash. The spectrum covers a total of 32 million people in 29 markets. The transaction further enhances our portfolio of nationwide broadband spectrum and enables the expansion of LTE coverage to new markets.

On November 7, 2013, we filed a registration statement on Form S-3 under the Securities Act of 1933, as amended (the “Securities Act”), using the “shelf” registration process. This shelf registration statement allows us to offer and sell not only our common stock, but also other debt or equity securities of the Company and certain subsidiaries in one or more offerings, as further described in the accompanying prospectus.

On November 14, 2013, we entered into an underwriting agreement pursuant to which we agreed to issue and sell 66,150,000 shares of our common stock, par value $0.00001 per share, at a public offering price of $25.00 per share (the “Common Stock Offering”). The Common Stock Offering is expected to close on November 20, 2013. The net proceeds of the Common Stock Offering are expected to be approximately $1.6 billion, after deducting underwriting discounts and commissions and estimated offering expenses payable by us. In connection with the Common Stock Offering, we granted the underwriters a 30-day option (the “Underwriters’ Option”) to purchase up to an additional 6,615,000 shares of our common stock at a public offering price of $25.00 per share, which was exercised in full on November 15, 2013. The Common Stock Offering is not contingent upon the completion of this offering of the notes, and this offering of the notes is not contingent upon the completion of the Common Stock Offering.

On November 15, 2013, we entered into an amendment to the Working Capital Facility (as defined under “Description of Other Indebtedness and Certain Lease Obligations—Working Capital Facility”) that changed the maximum Debt to Cash Flow Ratio permitted by certain financial and indebtedness covenants, compliance with which is a condition to borrowing under the Working Capital Facility. The amendment sets the maximum Debt to Cash Flow Ratio applicable to these covenants at 5.00 to 1.00 (for fiscal periods ending on or prior to December 31, 2013), 4.50 to 1.00 (for fiscal periods ending after December 31, 2013 and on or prior to December 31, 2014) and 4.00 to 1.00 (for fiscal periods ending after December 31, 2014).

• effectively subordinated to the Issuer’s existing and future secured indebtedness, to the extent of the value of the Issuer’s assets constituting collateral securing that indebtedness; and

• structurally subordinated to any existing and future indebtedness and other liabilities and preferred stock of the Issuer’s non-guarantor subsidiaries.

Assuming that on September 30, 2013, we had completed the offering of the notes, we would have had approximately $22.6 billion of senior indebtedness outstanding, approximately $0.4 billion of which would have been secured (and including approximately $2.49 billion in long term financial obligation relating to the Tower Transaction (as defined under “Unaudited Pro Forma Condensed Combined Financial Information”)). The notes would be effectively subordinated to this secured debt to the extent of the value of the assets constituting collateral securing this secured debt.

Note Guarantees The notes will be guaranteed by Parent, the Issuer’s wholly-owned domestic restricted subsidiaries (other than certain designated special purpose entities, a certain reinsurance subsidiary and immaterial subsidiaries), all of the Issuer’s restricted subsidiaries that guarantee certain of its indebtedness, and any future subsidiary of Parent that directly or indirectly owns any equity interests of the Issuer. See “Description of Notes—Brief Description of the Notes and the Note Guarantees—The Note Guarantees.” Each guarantee of the notes will be an unsecured, unsubordinated obligation of that guarantor and will rank:

• senior in right of payment to any future subordinated indebtedness of that guarantor to the extent that such indebtedness provides by its terms that it is subordinated in right of payment to such guarantor’s guarantee of the notes;

• equally in right of payment with any existing and future indebtedness and other liabilities of that guarantor that are not by their terms subordinated to the notes, including, without limitation, any guarantees of our Existing Senior Notes;

S-7

• effectively subordinated to that guarantor’s existing and future secured indebtedness, to the extent of the value of the assets of such guarantor constituting collateral securing that indebtedness; and

• structurally subordinated to all of the liabilities and preferred stock of any subsidiaries of such guarantor that do not guarantee the notes.

As of September 30, 2013, the Issuer’s subsidiaries that will not guarantee the notes had approximately $1.0 billion of total assets (excluding receivables due from the Issuer and its guarantor subsidiaries) and $2.3 billion in indebtedness, other liabilities and preferred stock.

Certain Covenants The indenture governing the notes contains covenants that, among other things, limit the ability of the Issuer and its restricted subsidiaries to:

• incur more debt;

• pay dividends and make distributions;

• make certain investments;

• repurchase stock;

• create liens or other encumbrances;

• enter into transactions with affiliates;

• enter into agreements that restrict dividends or distributions from subsidiaries; and

• merge, consolidate or sell, or otherwise dispose of, substantially all of their assets.

These covenants are subject to a number of important limitations and exceptions that are described later in this prospectus supplement under the caption “Description of Notes—Certain Covenants.” If the notes are assigned an investment grade rating by at least two of Standard & Poor’s Rating Services (“Standard & Poor’s”), Moody’s Investors Service, Inc. (“Moody’s”) and Fitch Ratings, Inc. (“Fitch”) and no default has occurred or is continuing, certain covenants will cease to apply and will not be later reinstated even if the rating of the notes should subsequently decline. See “Description of Notes—Certain covenants—Changes in covenants when notes rated investment grade.”

Asset Sale Proceeds If the Issuer or its restricted subsidiaries engage in certain types of asset sales, the Issuer generally must use the net cash proceeds from the sale either to make investments in its business (through capital

S-8

expenditures, acquisitions or otherwise) or to repay permanently debt under credit facilities or secured by assets sold within a certain period of time after such sale; otherwise the Issuer must make an offer to purchase, on a pro rata basis, a principal amount of the notes of each series and other pari passu indebtedness equal to the excess net cash proceeds. The purchase price of the notes of each series would be 100% of their principal amount, plus accrued and unpaid interest, to, but not including, the repurchase date. See “Description of Notes—Repurchase at the option of holders—Asset sales.”

Change of Control Triggering Event If the Issuer experiences certain change of control triggering events, the Issuer must make an offer to each holder to repurchase the notes of each series at a price in cash equal to 101% of their principal amount, plus accrued and unpaid interest, if any, to, but not including, the purchase date. See “Description of Notes—Repurchase at the option of holders—Change of control triggering event.”

Use of Proceeds We expect to use the net proceeds from this offering for general corporate purposes, including capital investments and acquisition of additional spectrum. See “Use of Proceeds.”

Absence of Public Market for the Notes The notes will be a new class of security and there is currently no established trading market for the notes. The underwriters have advised us that certain underwriters intend to make a market in the notes. However, they are not obligated to do so and they may discontinue any market making at any time in their sole discretion. As a result, a liquid market for the notes may not be available if you wish to sell your notes. We do not intend to apply for a listing or quotation of the notes on any securities exchange or any automated dealer quotation system.

Risk Factors You should consider carefully all of the information set forth in this prospectus supplement, the accompanying prospectus and the documents incorporated by reference herein and, in particular, you should carefully evaluate the specific factors under “Risk Factors” beginning on page S-16 of this prospectus supplement and those risk factors incorporated by reference herein.

(1) Adjusted EBITDA is a non-GAAP financial measure utilized by our management to monitor the financial performance of our operations. This measurement, together with GAAP measures such as revenue and operating income, assists management in its decision-making process related to the operation of the business. We use Adjusted EBITDA internally as a metric to evaluate and compensate our personnel and management for their performance, and as a benchmark to evaluate our operating performance in comparison to our competitors. Management also uses Adjusted EBITDA to measure, from period-to-period, our ability to provide cash flows to meet future debt services, capital expenditures and working capital requirements and fund future growth.

We believe that analysts and investors use Adjusted EBITDA as a supplemental measure to evaluate our overall operating performance and that this metric facilitates comparisons with other wireless communications companies. 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 GAAP. Adjusted EBITDA is calculated by adding back interest expense (net of interest income), taxes, depreciation and amortization expense, impairment charges, restructuring costs, other income and (expense), net, and other transactions that are not reflective of our ongoing operating performance to net income.

S-12

The following table reconciles Adjusted EBITDA to net (loss) income which we consider to be the most directly comparable GAAP financial measure to Adjusted EBITDA.

(a) Other, net of $133 million and $123 million for the nine months ended September 30, 2012 and year ended December 31, 2012, respectively, primarily related to a net gain from a spectrum transaction. Other, net for the year ended December 31, 2011 represents AT&T transaction-related costs incurred from the terminated AT&T acquisition of T-Mobile USA. Other, net transactions may not agree in total to the other, net classification in the Consolidated Statements of Operations and Comprehensive Income (Loss) due to certain routine operating activities, such as insignificant routine spectrum license exchanges that would be expected to reoccur, and are therefore not excluded from Adjusted EBITDA.

(2) Adjusted EBITDA as a percentage of service revenues is calculated by dividing Adjusted EBITDA by total service revenues.

(3) Capital expenditures consist of amounts paid for construction and purchase of property and equipment.

(4) Branded churn is defined as the number of branded customers whose service was discontinued, expressed as a rounded monthly percentage of the average number of branded customers during the specified period. T-Mobile believes that churn, which is a measure of customer retention and loyalty, provides relevant and useful information and is used by management to evaluate the operating performance of our business.

(5) ARPU represents the average monthly service revenue earned from customers. Branded ARPU is calculated by dividing service revenues from branded customers for the specified period by the average branded customers during the period, and further dividing by the number of months in the period. Branded postpaid ARPU is calculated by dividing branded postpaid service revenues for the specified period by the average branded postpaid customers during the period, and further dividing by the number of months in the period. Branded prepaid ARPU is calculated by dividing branded prepaid service revenues for the specified period by the average branded prepaid customers during the period, and further dividing by the number of months in the period. T-Mobile believes ARPU provides management with useful information to evaluate the service revenues generated from our customer base. The following tables illustrate the calculation of ARPU and reconcile ARPU to related service revenues, which we consider to be the most directly comparable GAAP financial measure to ARPU.

Branded Prepaid ARPU	$	34.02	$	26.55	$	26.85	$	24.27	$	24.18

(6) Branded Cost Per Gross Addition (“Branded CPGA”) is determined by dividing the costs of acquiring new customers, consisting of customer acquisition expenses plus the subsidy loss related to acquiring new customers for the specified period, by gross branded customer additions during the period. The subsidy loss related to acquiring new customers consists primarily of the excess of handset and accessory costs over related revenues incurred to acquire new customers. Additionally, the equipment subsidy loss associated with retaining existing customers, is excluded from this measure as Branded CPGA is intended to reflect only the acquisition costs to acquire new customers.

T-Mobile utilizes Branded CPGA to assess the initial capital invested in customers and determine the number of months to recover customer acquisition costs. This measure also allows T-Mobile to compare average acquisition costs per new customer to those of other wireless telecommunications providers, although other providers may calculate this measure differently. Equipment sales related to new customers are deducted from customer acquisition expenses in this calculation as they represent amounts paid by customers at the time their service is activated that reduce the acquisition cost of those customers. Additionally, equipment costs associated with retaining existing customers are excluded as this measure is intended to reflect only the acquisition costs related to new customers. The following table reconciles total costs used in the calculation of Branded CPGA to customer acquisition expenses, which T-Mobile considers to be the most directly comparable GAAP financial measure to Branded CPGA.

Branded CPGA	$	332		$	388		$	394		$	424		$	409

(7) Branded Cost Per User (“Branded CPU”) is determined by dividing network costs and general and administrative expenses plus the subsidy loss unrelated to customer acquisition, by the sum of the average monthly number of branded customers during such period. Additionally, the cost of serving customers includes the costs of providing handset insurance services.

S-14

T-Mobile utilizes Branded CPU as a tool to evaluate the non-acquisition related cash expenses associated with ongoing business operations on a per customer basis, to track changes in these non-acquisition related cash costs over time, and to help evaluate how changes in business operations affect non-acquisition related cash costs per customer. In addition, Branded CPU provides management with a useful measure to compare non-acquisition related cash costs per customer with those of other wireless telecommunications providers. The following table reconciles total costs used in the calculation of Branded CPU to network costs, which T-Mobile considers to be the most directly comparable GAAP financial measure to Branded CPU.

Non-GAAP financial measures

In managing our business and assessing financial performance, we supplement the information provided by financial statement measures prepared in accordance with generally accepted accounting principles (“GAAP”) in the United States of America (“GAAP measures”), such as operating income (loss), with non-GAAP measures, including Adjusted EBITDA, Branded Cost Per Gross Addition (“Branded CPGA”) and Branded Cost Per User (“Branded CPU”), which measure the financial performance of operations, and several customer focused performance metrics that are widely used in the wireless communications industry. Branded CPGA, Branded CPU and Adjusted EBITDA are utilized by our management to evaluate our operating performance, and in the case of Adjusted EBITDA, our ability to meet liquidity requirements. In addition to metrics involving the numbers of customers, these metrics also include measures related to Average Revenue Per User (“ARPU”), which measures service revenue per customer, and churn, which measures turnover in our customer base.

A non-GAAP financial measure is defined as a numerical measure of a company’s financial performance that (i) excludes amounts, or is subject to adjustments that have the effect of excluding amounts, that are included in the comparable measure calculated and presented in accordance with GAAP in the statement of income or statement of cash flows, or (ii) includes amounts, or is subject to adjustments that have the effect of including amounts, that are excluded from the comparable measure so calculated and presented.

We believe these measures are important in understanding the performance of operations from period to period, and that these measures, which are common in the wireless industry, facilitate key operating performance comparisons with other companies in the wireless industry. However, we caution investors that our presentations of these measures may not be comparable to similar measures as disclosed by other issuers, because other companies in the wireless industry may calculate these measures differently. Because of these limitations, investors should consider these non-GAAP measures alongside other performance measures and liquidity measures, including our GAAP measures, as well as the reconciliations of the impact of the components adjusted for in the non-GAAP financial measures.

Risk factors

An investment in the notes involves a high degree of risk. Prior to making a decision about investing in the notes, you should carefully consider the following risks and uncertainties. If any of the risks described in this prospectus supplement or accompanying prospectus, or the risks described in any documents incorporated by reference in this prospectus supplement or the accompanying prospectus, actually occur, our business, prospects, financial condition or operating results could be harmed. In such case, the trading price of the notes could decline, and you may lose all or part of your investment.

Risks related to the notes

Our substantial indebtedness could adversely affect our business, financial condition and operating results, and senior creditors would have a secured claim to any collateral securing the debt owed to them.

We have, and we expect that we will continue to have, a significant amount of debt. Assuming that on September 30, 2013, we had completed the offering of the notes, we would have had approximately $22.6 billion of outstanding indebtedness, including $19.6 billion of outstanding indebtedness under our senior notes, approximately $0.4 billion of capital leases (and including approximately $2.49 billion in long term financial obligation relating to the Tower Transaction), and $500 million available for borrowing under the Working Capital Facility.

Our ability to make payments on debt, to repay existing indebtedness when due and to fund operations and significant planned capital expenditures will depend on our ability to generate cash in the future. Our ability to produce cash from operations is subject to a number of risks, including:

• introduction of new products and services by us or our competitors, changes in service plans or pricing by us or our competitors, or promotional offers;

• customers’ acceptance of our service offerings;

• our ability to maintain our current cost structure; and

• our ability to continue to grow our customer base and maintain projected levels of churn.

Our substantial debt service obligations could have important material consequences to you, including the following:

• limiting our ability to borrow money or sell stock to fund working capital, capital expenditures, debt service requirements, acquisitions, technological initiatives and other general corporate purposes;

• making it more difficult for us to make payments on indebtedness and satisfy obligations under the notes;

• increasing our vulnerability to general economic downturns and industry conditions and limiting our ability to withstand competitive pressure;

• limiting our flexibility in planning for, or reacting to, changes in our business or the communications industry;

• limiting our ability to increase our capital expenditures to roll out new services or to upgrade our networks to new technologies, such as LTE;

S-16

• limiting our ability to purchase additional spectrum, expand existing service areas or develop new metropolitan areas in the future;

• reducing the amount of cash available for working capital needs, capital expenditures for existing and new markets and other corporate purposes by requiring us to dedicate a substantial portion of cash flow from operations to the payment of principal of, and interest on, indebtedness; and

• placing us at a competitive disadvantage to our competitors who are less leveraged than we are.

Any of these risks could impair our ability to fund our operations or limit our ability to obtain additional spectrum, or limit our ability to expand our business as planned, which could have a material adverse effect on our business, financial condition, and operating results.

In addition, a substantial portion of our debt bears interest at fixed rates subject to a “reset” two, two and a half, or three years after the closing of the Business Combination Transaction or at a variable rate. The reset will cause the interest rate of the relevant debt securities to be recalculated according to a formula which depends in part upon designated indices (which are tied to market yields for certain securities) and other benchmark debt securities, only a portion of which is calculated based on the trading prices of our indebtedness. If market interest rates increase, variable-rate debt and debt at fixed rates subject to a “reset,” on the reset date and thereafter, will create higher debt service requirements, which could adversely affect our cash flow. While we may enter into agreements limiting our exposure to higher interest rates in the future, any such agreements may not offer complete protection from this risk, and any portion not subject to such agreements would have full exposure to higher interest rates. Interest rates for such benchmark indices and debt securities are highly sensitive to many factors, including domestic and international economic and political conditions, policies of governmental and regulatory agencies, developments affecting the financial or operating results or prospects of the issuer of the benchmark securities or of securities referenced in the benchmark indices, and other factors beyond our control. As a result, a significant increase in these interest rates at the time that the relevant debt securities are recalculated could have an adverse effect on our financial position and results of operations.

Even with our current levels of indebtedness, we may incur additional indebtedness. This could further exacerbate the risks associated with our leverage.

Although we have substantial indebtedness, we may still be able to incur significantly more debt as market conditions and contractual obligations permit, which could further reduce the cash available to invest in operations, as a result of increased debt service obligations. The terms of the agreements governing our long-term indebtedness allow for the incurrence of additional indebtedness by us and our subsidiaries, subject to specified limitations. The more leveraged we become, the more we, and in turn the holders of our securities, become exposed to the risks described above in the risk factor entitled “Our substantial indebtedness could adversely affect our business, financial condition and operating results and senior creditors would have a secured claim to any collateral securing the debt owed to them.”

There can be no assurance that sufficient funds will be available to us under our existing indebtedness or otherwise. Further, should we need to raise additional capital, the foreign ownership restrictions mandated by the Federal Communications Commission (“FCC”), and applicable to us, could limit our ability to attract additional equity financing outside the United States. If we were able

S-17

to obtain funds, it may not be on terms and conditions acceptable to us, which could limit or preclude our ability to pursue new opportunities, expand our service, upgrade our networks, engage in acquisitions, or purchase additional spectrum, thus limiting our ability to expand our business which could have a material adverse effect on our business, financial condition and operating results.

The notes and the guarantees will be unsecured and effectively subordinated to the Issuer’s and the guarantors’ existing and future secured indebtedness and structurally subordinated to the indebtedness and other liabilities of the Issuer’s non-guarantor subsidiaries.

The notes and the guarantees will be general unsecured, unsubordinated obligations ranking effectively junior in right of payment to all existing and future secured debt of the Issuer and of each guarantor to the extent of the value of the collateral securing such debt, and will be structurally subordinated to any existing or future indebtedness, preferred stock and other liabilities of the Issuer’s non-guarantor subsidiaries. The notes also will permit us to incur certain additional secured debt.

If the Issuer or a guarantor is declared bankrupt, becomes insolvent or is liquidated or reorganized, any secured debt of the Issuer or of that guarantor will be entitled to be paid in full from the Issuer’s assets or the assets of the guarantor, as applicable, securing that debt before any payment may be made with respect to the notes or the guarantees. Holders of the notes will participate ratably in any remaining assets with all holders of the Issuer’s unsecured indebtedness that is not by its terms subordinated to the notes, including all of the Issuer’s other general creditors, based upon the respective amounts owed to each holder or creditor. In any of the foregoing events, there may not be sufficient assets to pay the indebtedness and other obligations owed to secured creditors and the amounts due on the notes. As a result, holders of the notes would likely receive less, ratably, than holders of secured indebtedness. It is possible that there will be no assets from which claims of holders of the notes can be satisfied.

Assuming that on September 30, 2013, we had completed the offering of the notes, we would have had approximately $22.6 billion of outstanding indebtedness, including $19.6 billion of outstanding indebtedness under our senior notes (including the notes offered hereby), approximately $0.4 billion of which would have been secured (and including approximately $2.49 billion of long term financial obligation relating to the Issuer’s tower transaction). The notes would be effectively subordinated to this secured debt to the extent of the value of the assets constituting collateral securing this secured debt.

In addition, creditors of current and future subsidiaries of the Issuer that do not guarantee the notes would have claims, with respect to the assets of those subsidiaries that rank structurally senior to the notes. As of September 30, 2013, the Issuer’s subsidiaries that will not guarantee the notes had approximately $1.0 billion of total assets (excluding receivables due from the Issuer and its guarantor subsidiaries) and $2.3 billion in indebtedness, other liabilities and preferred stock. In the event of any distribution or payment of assets of such subsidiaries in any dissolution, winding up, liquidation, reorganization, or other bankruptcy proceeding, the claims of those creditors must be satisfied prior to making any such distribution or payment to the Issuer in respect of direct or indirect equity interests in such subsidiaries. Certain subsidiaries of Issuer (such as special purpose entities, a reinsurance subsidiary and immaterial subsidiaries) will not guarantee the notes. See “Description of Notes—Brief Description of the Notes and the Note Guarantees—The Note Guarantees.”

S-18

To service our debt, we will require a significant amount of cash, which may not be available to us.

Our ability to meet existing or future debt obligations and to reduce indebtedness will depend on future performance and the other cash requirements of our businesses. Our performance, to a certain extent, is subject to general economic conditions and financial, competitive, business, political, regulatory and other factors that are beyond our control. In addition, our ability to borrow funds in the future to make payments on debt will depend on the satisfaction of covenants in the indentures governing our Existing Senior Notes and the notes offered hereby, other debt agreements and other agreements we may enter into in the future. Specifically, under the Working Capital Facility (so long as any amounts are outstanding thereunder), we will need to maintain certain financial ratios. We cannot assure you that we will continue to generate sufficient cash flow from operations or that future equity issuances or borrowings will be available to us in an amount sufficient to enable us to service debt or repay all indebtedness in a timely manner or on favorable or commercially reasonable terms, or at all. If we are unable to satisfy financial covenants under the Working Capital Facility or generate sufficient cash to timely repay debt, our lenders could accelerate the maturity of some or all of our outstanding indebtedness. As a result, we may need to refinance all or a portion of our remaining existing indebtedness prior to its maturity. Disruptions in the financial markets, the general amount of debt refinancings occurring at the same time, and our financial position and performance could make it more difficult to obtain debt or equity financing on reasonable terms or at all. In addition, instability in the global financial markets has from time to time resulted in periodic volatility in the capital markets. This volatility could limit our access to the credit markets, leading to higher borrowing costs or, in some cases, the inability to obtain financing on terms that are acceptable to us, or at all. Any such failure to obtain additional financing could jeopardize our ability to repay, refinance or reduce debt obligations.

Upon certain events including a change of control, we may be required to offer to repurchase all of the Existing Senior Notes and all of the notes offered hereby and we may not have the ability to finance such repurchase.

The indentures governing our Existing Senior Notes and the notes offered hereby, provide that, upon the occurrence of certain change of control triggering events, which change of control triggering events include a change of control combined with certain ratings downgrades or withdrawals as described further under “Description of Notes—Repurchase at the Option of Holders—Change of Control Triggering Event”, the Issuer will be required to offer to repurchase all outstanding Existing Senior Notes and the notes offered hereby, at 101% of the principal amount thereof plus accrued and unpaid interest, if any, to the date of repurchase. In addition, any change of control is expected to cause an event of default under the Working Capital Facility, entitling the lenders to declare all outstanding amounts thereunder to be immediately due and payable. We may not have sufficient access to funds at the time of the change of control triggering event to make the required repurchase of the Existing Senior Notes and the notes offered hereby, and repay outstanding amounts under the Working Capital Facility or contractual restrictions may not allow such repurchases or repayments.

In addition, pursuant to a noteholder agreement entered into between us and Deutsche Telekom, upon the occurrence of certain events, Deutsche Telekom will have the right to require us to repurchase any April 2013 senior notes held by Deutsche Telekom or any of its subsidiaries (other than Parent or any of its subsidiaries), even if a change of control triggering event has not occurred. If such an event were to occur, we may not have sufficient funds to pay the purchase price in any required repurchase offers and may be required to obtain third-party financing in order to do so. However, we may not be able to obtain such financing on commercially reasonable terms, or at all.

S-19

The failure to purchase the Existing Senior Notes or the notes offered hereby, as required under the respective indentures, or the failure to purchase the April 2013 senior notes as required under the noteholder agreement, would result in a default under such indentures or breach of such noteholder agreement, which could have material adverse consequences for us and the holders of the notes. Any such event of default would likely trigger an event of default on other outstanding or future indebtedness.

The indentures governing our Existing Senior Notes and the notes offered hereby, and our Working Capital Facility include restrictive covenants that limit our operating flexibility.

The indentures governing our Existing Senior Notes and the notes offered hereby, as well as the Working Capital Facility, impose material restrictions on us. These restrictions, subject in certain cases to ordinary course of business and other exceptions, may limit our ability to engage in some transactions, including the following:

• incurring additional debt;

• paying dividends, redeeming capital stock or making other restricted payments or investments;

• selling assets, properties or licenses;

• developing assets, properties or licenses which we have or in the future may procure;

• creating liens on assets;

• participating in future FCC auctions of spectrum or private sales of spectrum;

• merging, consolidating or disposing of substantially all assets;

• entering into transactions with affiliates; and

• placing restrictions on the ability of subsidiaries to pay dividends or make other payments.

Any future debt that we incur may, and the Working Capital Facility does, contain financial maintenance covenants. These restrictions could limit our ability to obtain debt financing, repurchase stock, refinance or pay principal on our outstanding debt, complete acquisitions for cash or debt or react to changes in our operating environment or the economy.

Any failure to comply with the restrictions of the indentures governing our Existing Senior Notes and the notes offered hereby, or the Working Capital Facility or certain current and any subsequent financing agreements may result in an event of default under these agreements, which in turn may result in defaults or acceleration of obligations under these agreements and other agreements, giving our lenders and other debt holders the right to require us to repay all amounts then outstanding and to terminate any commitments they may have made to provide us with further funds.

The guarantees may not be enforceable because of fraudulent conveyance laws.

The guarantors’ guarantees of the notes may be subject to review under federal bankruptcy law or relevant state fraudulent conveyance laws if we or any guarantor file a petition for bankruptcy or our creditors file an involuntary petition for bankruptcy against us or any guarantor. Under these laws, if a court were to find that, at the time a guarantor incurred debt (including debt represented by the guarantee), such guarantor:

• incurred this debt with the intent of hindering, delaying or defrauding current or future creditors; or

• received less than reasonably equivalent value or fair consideration for incurring this debt, and the guarantor:

• was insolvent or was rendered insolvent by reason of the related financing transactions;

S-20

• was engaged in, or about to engage in, a business or transaction for which its remaining assets constituted unreasonably small capital to carry on its business; or

• intended to incur, or believed that it would incur, debts beyond its ability to pay these debts as they mature, as all of the foregoing terms are defined in or interpreted under the relevant fraudulent transfer or conveyance statutes;

then the court could void the guarantee or subordinate the amounts owing under the guarantee to the guarantor’s presently existing or future debt or take other actions detrimental to you.

The measure of insolvency for purposes of the foregoing considerations will vary depending upon the law of the jurisdiction that is being applied in any such proceeding. Generally, an entity would be considered insolvent if, at the time it incurred the debt or issued the guarantee:

• it could not pay its debts or contingent liabilities as they become due;

• the sum of its debts, including contingent liabilities, is greater than its assets, at a fair valuation; or

• the present fair saleable value of its assets is less than the amount required to pay the probable liability on its total existing debts and liabilities, including contingent liabilities, as they become absolute and mature.

If a guarantee is voided as a fraudulent conveyance or found to be unenforceable for any other reason, you will not have a claim against that obligor and will only be our creditor or that of any guarantor whose obligation was not set aside or found to be unenforceable. In addition, the loss of a guarantee will constitute an event of default under the indentures relating to our Existing Senior Notes and the notes offered hereby, and will constitute an event of default under the Working Capital Facility, which events of default would allow the relevant noteholders or lenders to accelerate the amounts due and payable thereunder, and we may not have the ability to pay any such amounts.

The indenture governing the notes will contain a provision intended to limit each guarantor’s liability to the maximum amount that it could incur without causing the incurrence of obligations under its guarantee to be a fraudulent transfer. This provision may not be effective to protect the guarantees from being voided under fraudulent transfer law, or may eliminate the guarantor’s obligations or reduce the guarantor’s obligations to an amount that effectively makes the guarantee worthless. In a recent Florida bankruptcy case, this kind of provision was found to be ineffective to protect the guarantees.

Many of the covenants in the indenture governing the notes will not apply if the notes are rated investment grade.

The indenture governing the notes provides that many of its covenants will cease to apply to us if the notes are rated investment grade by two or more of Moody’s, Standard & Poor’s and Fitch, provided at such time no default or event of default has occurred and is continuing. The indenture further provides that these covenants will not be later reinstated in the event that the ratings of the notes subsequently decline. These covenants restrict, among other things, our ability to pay dividends, to incur debt and to enter into certain other transactions. There can be no assurance that the notes will ever be rated investment grade. However, termination of these covenants would allow us to engage in certain transactions that would not be permitted while these covenants were in force. See “Description of Notes—Certain Covenants—Changes in Covenants When Notes Rated Investment Grade.”

S-21

If we or our existing investors sell our debt securities after this offering, the market price of the notes could decline.

The market price of the notes could decline as a result of sales of the Issuer’s debt securities in the market after this offering, or the perception that such sales could occur. These sales, or the possibility that these sales may occur, also might make it more difficult for the Issuer to sell other debt securities in the future at a time and on terms that it deems appropriate.

After the completion of this offering, the Issuer would have outstanding approximately $19.2 billion in aggregate principal amount of debt securities, maturing in 2018 through 2024, all of which would be senior unsecured debt securities. Parent’s majority shareholder, Deutsche Telekom, holds approximately $5.6 billion of these debt securities, maturing in 2019 through 2023. We have on file an effective shelf registration statement with respect to these debt securities held by Deutsche Telekom, and Deutsche Telekom could sell all or any portion of them at any time.

There is no established trading market for the notes and no guarantee that a market will develop or that you will be able to sell your notes.

The notes are a new issue of securities for which there is no established trading market. An active trading market may not develop for the notes. Historically, the market for non-investment grade debt has been subject to disruptions that have caused substantial volatility in the prices of securities similar to the notes. The market, if any, for the notes may not be free from similar disruptions, and any such disruptions may adversely affect the prices at which you may sell your notes if at all. In addition, subsequent to their initial issuance, the notes may trade at a discount from their initial offering price, depending upon prevailing interest rates, the market for similar notes, our operating performance and financial condition and other factors. We do not intend to apply for listing or quotation of the notes on any securities exchange or any automated dealer quotation system.

The trading prices for the notes will be directly affected by many factors, including our credit rating.

Credit rating agencies continually revise their ratings for companies they follow, including us. Any ratings downgrade could adversely affect the trading price of the notes, or the trading market for the notes, to the extent a trading market for the notes develops. The condition of the financial and credit markets and prevailing interest rates have fluctuated in the past and are likely to fluctuate in the future and any fluctuation may impact the trading price of the notes.

Risks related to our business and the wireless industry

Increasing competition for wireless customers could adversely affect our operating results.

We have multiple wireless competitors in each of our service areas, some of which have greater resources than us, and compete for customers based principally on service/device offerings, price, call quality, data use experience, coverage area, and customer service. In addition, we are facing growing competition from providers offering services using alternative wireless technologies and IP-based networks, as well as traditional wireline networks. We expect market saturation to continue to cause the wireless industry’s customer growth rate to be moderate in comparison with historical growth rates or possibly negative, leading to increased competition for customers.

S-22

We also expect that our customers’ growing demand for data services will place constraints on our network capacity. This competition and our capacity issues will continue to put pressure on pricing and margins as companies compete for potential customers. Our ability to respond will depend on, among other things, continued absolute and relative improvement in network quality and customer services, effective marketing and selling of products and services, attractive pricing, and cost management, all of which will involve significant expenses.

Consolidation in the wireless industry through mergers, acquisitions and joint ventures could create increased competition.

Joint ventures, mergers, acquisitions and strategic alliances in the wireless industry have resulted in and are expected to result in larger competitors competing for a limited number of customers. The two largest national wireless broadband mobile carriers currently serve a significant percentage of all wireless customers, and hold significant spectrum and other resources. Our largest competitors may be able to enter into exclusive handset or content arrangements, execute pervasive advertising and marketing campaigns, or otherwise improve their cost position relative to ours. In addition, the refusal of our large competitors to provide critical access to resources and inputs, such as roaming services on reasonable terms, may improve their position within the wireless broadband mobile services industry. These factors, together with the effects of the increasing aggregate penetration of wireless services in all metropolitan areas, and the ability of our larger competitors to use resources to build out their networks and to quickly deploy advanced technologies, which have made it more difficult for smaller carriers like us to attract and retain customers, may adversely affect our competitive position and ability to grow, which would have a material adverse effect on our business, financial condition, and operating results.

The failure to successfully integrate the T-Mobile and MetroPCS businesses in the expected time frame could adversely affect our future operating results. Many of the anticipated benefits of the combination may not be realized for a significant period of time, if at all.

Our success will depend, in large part, on our ability to realize the anticipated benefits, including projected synergies and cost savings, from combining the T-Mobile business with the MetroPCS business. This integration will be complex, time-consuming, require significant capital expenditures, and may divert management’s time and attention from the business. The failure to successfully integrate and manage the challenges presented by the integration process may prevent us from achieving the anticipated benefits of the business combination of T-Mobile and MetroPCS and have a material adverse effect on our business, financial condition and operating results.

Potential difficulties in the integration process include, among others, the following:

• unexpected costs incurred in integrating the T-Mobile and MetroPCS businesses or inability to achieve the cost savings anticipated to result from the business combination;

• migrating customers from the legacy MetroPCS network to our global system for mobile communications, which we refer to as GSM, evolved high speed packet access, which we refer to as HSPA+, and LTE networks;

• decommissioning the legacy MetroPCS network;

• integrating existing back office and customer facing information and billing systems, cell sites and network infrastructure, customer service programs, and distributed antenna systems;

S-23

• combining or coordinating product and service offerings, subscriber plans, customer services, and sales and marketing approaches;

• addressing the effects of the business combination on our business and the previously established relationships between each of T-Mobile and MetroPCS and their employees, customers, suppliers, content providers, distributors, dealers, retailers, regulators, affiliates, joint venture partners, and the communities in which they operated; and

• difficulties in consolidating and preparing the Company’s financial statements, or having to restate the financial statements of the Company.

Many of the anticipated synergies are not expected to occur for a significant time period and will require substantial capital expenditures in the near term to be fully realized. Even if we are able to integrate the two businesses successfully, we may not realize the full anticipated benefits of the merger, including anticipated synergies expected from the integration, or achieve such benefits within the anticipated time frame or at all.

If we are unable to attract and retain wireless subscribers our financial performance will be impaired.

Customer demand for our products and services is impacted by numerous factors including, but not limited to, our service offerings, pricing, network performance, customer perceptions, competitive offers, sales and distribution channels, economic conditions and customer service. Managing these factors, and customers’ expectations of these factors, is essential in attracting and retaining customers.

We continuously incur capital expenditures and operating expenses in order to improve and enhance our products, services, applications, and content to remain competitive and to keep up with our customer demand. If we fail to improve and enhance our products and services or expand the capacity of, or make upgrades to, our network to remain competitive, or if we fail to keep up with customer demand, including by maintaining access to desired handsets, content and features, our ability to attract and retain customers would be adversely affected. In particular, our gross new subscriber activations may decrease and our subscriber churn may increase, leaving us unable to meet the assumptions of our business plan. Even if we effectively manage the factors listed above that are within our control, there can be no assurance that our existing customers will not switch to another wireless provider or that we will be able to attract new customers. There would be a material adverse impact on our business, financial condition, and operating results if we are unable to grow our customer base at the levels we project, or achieve the aggregate levels of customer penetration that we currently believe are possible with our business model.

We no longer require consumers to sign annual service contracts for post-paid services and offer consumers equipment financing, and this strategy may not succeed in the long term.

With the launch of our ‘Simple Choice Plan’, we no longer require consumers to sign annual service contracts to obtain post-paid service, while offering Equipment Installment Plans (“EIPs”) to permit customers to finance handsets which they purchase from us. While we anticipate that we will continue to employ similar “Un-carrier” tactics as part of our business strategy, our service plans and EIP offerings may not meet our customers’ or potential customers’ needs, expectations, or demands. In addition, with this reduction in long-term service contracts, our customers may have residual commitments to us for device financing, but can discontinue their service at any time without penalty or advance notice to us. We cannot assure you that our strategies to address

S-24

customer churn will be successful. In addition, we may not be able to profitably replace customers who leave our service or replace them at all. We could experience reduced revenues and increased marketing costs to attract replacement customers if we experience a churn rate higher than we expect, which could reduce our profit margin and profitability. Our operational and financial performance may be adversely affected if we are unable to grow our customer base and achieve the customer penetration levels that we anticipate with this business model.

Certain retail customers have the option to pay for their devices in installments over a period of up to 24 months under our EIP. These EIP offerings subject us to increased risks relating to consumer credit issues, which could result in increases to our bad debt expense and potential write-offs of account balances under the EIPs. These arrangements may be particularly sensitive to changes in general economic conditions, as discussed below, and any declines in the credit quality of our customer base could have a material adverse effect on our operating results and financial condition.

We record EIP bad debt expense based on an estimate of the percentage of equipment revenue that will not be collected. This estimate is based on a number of factors including historical write-off experience, credit quality of the customer base, and other factors such as macro-economic conditions. We monitor the aging of our EIP receivables and write-off account balances if collection efforts are unsuccessful and future collection is unlikely based on customer credit ratings and the length of time from the original billing date. Equipment sales that are not reasonably assured to be collectible are recorded on a cash basis as payments are received.

If we are unable to take advantage of technological developments on a timely basis, then we may experience a decline in demand for our services or face challenges in implementing our business strategy.

In order to grow and remain competitive, we will need to adapt to future changes in technology, enhance our existing offerings, and introduce new offerings to address our current and potential customers’ changing demands. For example, we are in the process of transforming and upgrading our network to be the first in the United States to deploy LTE Release 10 and the first to use multimode integrated radios that can handle GSM, HSPA+ and LTE. As part of the network upgrade, we will install new equipment in approximately 35,000 cell sites and refarm our Personal Communications Service in the personal communications services (“PCS”) 1900 MHz spectrum band from second generation GSM services to HSPA+. Modernizing the network is subject to risk from equipment changes, refarming of spectrum, and migration of customers from existing spectrum bands. Scheduling and supplier delays, unexpected or increased costs, technological constraints, regulatory permitting issues, subscriber dissatisfaction, and other risks could cause delays in launching the new network, which could result in significant costs, or reduce the anticipated benefits of the upgrades. In addition, we recently entered into an agreement with Apple, Inc. to carry the iPhone 5 and other Apple products. This new agreement may result in a decrease in free cash flow, and there is no assurance that the agreement will be economically advantageous for us in the long-term.

In general, the development of new services in the wireless telecommunications industry will require us to anticipate and respond to the continuously changing demands of our customers, which we may not be able to do accurately or timely. We could experience a material adverse effect on our business, operations, financial position, and operating results if our new services fail to retain or gain acceptance in the marketplace or if costs associated with these services are higher than anticipated.

S-25

The scarcity and cost of additional wireless spectrum, and regulations relating to spectrum use, may adversely affect our business strategy and financial planning.

Based on industry trends, we believe that the average data usage of our customers will continue to rise. Therefore, at some point in the future we will need to acquire additional spectrum in order to continue our customer growth, expand into new areas, maintain our quality of service, meet increasing customer demands, and deploy new technologies. We will be at a competitive disadvantage and possibly experience erosion in the quality of service in certain areas if we fail to gain access to necessary spectrum before reaching capacity, especially below 1 GHz—low band spectrum.

The continued interest in, and aggregation of, spectrum by the largest national carriers may reduce our ability to acquire spectrum from other carriers or otherwise negatively impact our ability to gain access to spectrum through other means. As a result, we may need to acquire spectrum through government auctions and/or enter into spectrum sharing arrangements, which are subject to certain risks and uncertainties. For example, the Federal Communications Commission, or FCC, has encountered significant challenges in making additional spectrum available, which has created uncertainty about the timing and availability of spectrum through government auctions.

In addition, the FCC may impose conditions on the use of new wireless broadband mobile spectrum, including new restrictions or rules governing the use or access to current or future spectrum. This could increase pressure on capacity. Additional conditions that may be imposed by the FCC include more stringent build-out requirements, limited renewal rights, clearing obligations, or open access or net neutrality requirements that may make it less attractive or less economical to acquire spectrum. The FCC has a pending notice of proposed rulemaking to examine whether the current spectrum screen used in acquisitions of spectrum should be changed or whether a spectrum cap should be imposed. In addition, rules may be established for future government spectrum auctions that may negatively impact our ability to obtain spectrum economically or in appropriate configurations or coverage areas.

If we cannot acquire needed spectrum from the government or otherwise, if new or existing competitors acquire spectrum that will allow them to provide services competitive with our services, or if we cannot deploy services on a timely basis without burdensome conditions, at adequate cost, and while maintaining network quality levels, then our ability to attract and retain customers and our associated financial performance could be materially adversely affected.

Economic and market conditions may adversely affect our business and financial performance, as well as our access to financing on favorable terms or at all.

Our business and financial performance are sensitive to changes in general economic conditions, including changes in interest rates, consumer credit conditions, consumer debt levels, consumer confidence, rates of inflation (or concerns about deflation), unemployment rates, energy costs and other macro-economic factors. Market and economic conditions have been unprecedented and challenging in recent years. Continued concerns about the systemic impact of a long-term downturn, high underemployment and unemployment, high energy costs, the availability and cost of credit and unstable housing and credit markets have contributed to increased market volatility and economic uncertainty.

Continued or renewed market turbulence and weak economic conditions may materially adversely affect our business and financial performance in a number of ways. Our services are

S-26

available to a broad customer base, a significant segment of which may be more vulnerable to weak economic conditions. We may have greater difficulty in gaining new customers within this segment and existing customers may be more likely to terminate service due to an inability to pay. Competing for customers within this segment also puts pressure on our pricing structure and margins. In addition, the continued instability in the global financial markets has resulted in periodic volatility in the credit, equity, and fixed income markets. This volatility could limit our access to the credit markets, leading to higher borrowing costs or, in some cases, the inability to obtain financing on terms that are acceptable to us, or at all.

Continued weak economic conditions and tight credit conditions may also adversely impact our suppliers and dealers, some of which have filed for or may be considering bankruptcy, or may experience cash flow or liquidity problems or are unable to obtain or refinance credit such that they may no longer be able to operate. Any of these could adversely impact our ability to distribute, market, or sell our products and services. Sustained difficult, or worsening, general economic conditions could have a material adverse effect on our business, financial condition and results of operations.

Our reputation and financial condition could be materially adversely affected by system failures, security or data breaches, business disruptions, and unauthorized use or interference with our network and other systems.

To be successful, we must provide our customers with reliable, trustworthy service and protect the communications, location, and personal information shared or generated by our customers. We rely upon our systems and networks, and the systems and networks of other providers and suppliers, to provide and support our services and, in some cases, to protect our customers’ and our information. Failure of our or others’ systems, networks and infrastructure may prevent us from providing reliable service, or may allow for the unauthorized interception, destruction, use or dissemination of our customers’ or our company’s information. Examples of these risks include:

• denial of service and other malicious or abusive attacks by third parties, including cyber-attacks or other breaches of network or information technology security;

• human error;

• physical damage, power surges or outages, or equipment failure, including those as a result of severe weather, natural disasters, terrorist attacks, and acts of war;

• theft of customer/proprietary information: intrusion and theft of data offered for sale, competitive (dis)advantage, and/or corporate extortion;

• unauthorized access to our information technology, billing, customer care and provisioning systems and networks, and those of our suppliers and other providers;

• supplier failures or delays; and

• other systems failures or outages.

Such failures could cause us to lose customers, lose revenue, incur expenses, suffer reputational and goodwill damages, and subject us to litigation or governmental investigation. Remediation costs could include liability for information loss, repairing infrastructure and systems, and/or incentives offered to customers. Our insurance may not cover, or be adequate to fully reimburse us for, costs and losses associated with such events.

S-27

We rely on third-parties to provide specialized products or services for the operation of our business, and a failure or inability by such parties to provide these products or services could adversely affect our business, results of operations, and financial condition.

We depend heavily on suppliers and other third parties in order for us to efficiently operate our business. Our business is complex, and it is not unusual for multiple vendors located in multiple locations to help us to develop, maintain, and troubleshoot products and services, such as network components, software development services, and billing and customer service support. Our suppliers often provide services outside of the United States, which carries associated additional regulatory and legal obligations. We generally rely upon the suppliers to provide contractual assurances and accurate information regarding risks associated with their provision of products or services in accordance with our expectations and standards, and they may fail to do so.

Generally, there are multiple sources for the types of products and services we purchase or use. However, we currently rely on one key supplier for billing services, a limited number of suppliers for voice and data communications transport services, network infrastructure, equipment, handsets, and other devices, and, and payment processing services, among other products and services we rely on. Disruptions with respect to such suppliers, or failure of such suppliers to adequately perform, could have a material adverse on our financial performance.

In the past, our suppliers, contractors and third-party retailers have not always performed at the levels we expect or at the levels required by their contracts. Our business could be severely disrupted if key suppliers, contractors, service providers, or third-party retailers fail to comply with their contracts or become unable to continue the supply due to patent or other intellectual property infringement actions, or other disruptions. Our business could also be disrupted if we experience delays or service degradation during any transition to a new outsourcing provider or other supplier, or we were required to replace the supplied products or services with those from another source, especially if the replacement became necessary on short notice. Any such disruptions could have a material adverse effect on our business, results of operations and financial condition.

Our financial performance will be impaired if we experience high fraud rates related to device financing, credit cards, dealers, or subscriptions.

Our operating costs could increase substantially as a result of fraud, including device financing, customer credit card, subscription or dealer fraud. If our fraud detection strategies and processes are not successful in detecting and controlling fraud, whether directly or by way of the systems, processes, and operations of third parties such as national retailers, dealers and others, the resulting loss of revenue or increased expenses could have a materially adverse impact on our financial condition and results of operations.

Our significant indebtedness could adversely affect our business, financial condition and operating results.

Our ability to make payments on our debt, to repay our existing indebtedness when due, and to fund operations and significant planned capital expenditures will depend on our ability to generate cash in the future, which is in turn subject to the operational risks described elsewhere in this section. Our debt service obligations could have material adverse effects on our operations and financial results, including by:

• limiting our ability to borrow money or sell stock to fund our operational, financing or strategic needs;

S-28

• limiting our flexibility in planning for, or reacting to, changes in our business or the communications industry or pursuing growth opportunities;

• reducing the amount of cash available for other operational or strategic needs; and

• placing us at a competitive disadvantage to competitors who are less leveraged than we are.

In addition, a substantial portion of our debt, including $5.6 billion in principal amount of the notes we issued to Deutsche Telekom in connection with the business combination between T-Mobile USA and MetroPCS and borrowings under our $500 million credit facility with Deutsche Telekom, bears interest at variable rates. If market interest rates increase, variable-rate debt will create higher debt service requirements, which could adversely affect our cash flow. While we have and may enter into agreements limiting our exposure to higher interest rates in the future, any such agreements may not offer complete protection from this risk, and any portion not subject to such agreements would have full exposure to higher interest rates. Any of these risks could have a material adverse effect on our business, financial condition, and operating results.

Even with our current levels of indebtedness, we may incur additional indebtedness. This could further exacerbate the risks associated with our leverage.

Although we have substantial indebtedness, we may still be able to incur significantly more debt as market conditions and contractual obligations permit, which could further reduce the cash available to invest in operations, as a result of increased debt service obligations. The terms of the agreements governing our long-term indebtedness allow for the incurrence of additional indebtedness by us and our subsidiaries, subject to specified limitations. The more leveraged we become, the more we, and in turn the holders of our securities, become exposed to the risks described above in the risk factor entitled “Our substantial indebtedness could adversely affect our business, financial condition and operating results.”

There can be no assurance that sufficient funds will be available to us under our existing indebtedness or otherwise. Further, should we need to raise additional capital, the foreign ownership restrictions mandated by the FCC, and applicable to us, could limit our ability to attract additional equity financing outside the United States. If we were able to obtain funds, it may not be on terms and conditions acceptable to us, which could limit or preclude our ability to pursue new opportunities, expand our service, upgrade our networks, engage in acquisitions, or purchase additional spectrum, thus limiting our ability to expand our business which could have a material adverse effect on our business, financial condition and operating results.

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

The agreements governing our indebtedness impose significant operating and financial restrictions on us. These restrictions, subject in certain cases to customary baskets, exceptions and incurrence-based ratio tests, may limit our ability to engage in some transactions, including the following:

• incurring additional indebtedness and issuing preferred stock;

• paying dividends, redeeming capital stock or making other restricted payments or investments;

• selling or buying assets, properties or licenses;

• developing assets, properties or licenses which we have or in the future may procure;

• creating liens on assets;

• participating in future FCC auctions of spectrum or private sales of spectrum;

S-29

• engaging in mergers, acquisitions, business combinations, or other transactions;

• entering into transactions with affiliates; and

• placing restrictions on the ability of subsidiaries to pay dividends or make other payments.

These restrictions could limit our ability to react to changes in our operating environment or the economy. Any future indebtedness that we incur may contain similar or more restrictive covenants. Any failure to comply with the restrictions of our debt agreements may result in an event of default under these agreements, which in turn may result in defaults or acceleration of obligations under these agreements and other agreements, giving our lenders the right to terminate any commitments they had made to provide us with further funds and to require us to repay all amounts then outstanding. Any of these events would have a material adverse effect on our financial position and performance.

Our business and stock price may be adversely affected if our internal controls are not effective.

Section 404 of the Sarbanes-Oxley Act of 2002, as amended, and the SEC rules and regulations promulgated thereunder, require companies to conduct a comprehensive evaluation of their internal control over financial reporting. To comply with this statute, each year we are required to document and test our internal control over financial reporting; our management is required to assess and issue a report concerning our internal control over financial reporting; and our independent registered public accounting firm is required to report on the effectiveness of our internal control over financial reporting.

We cannot assure you that we will not discover material weaknesses in the future, including material weaknesses resulting from difficulties, errors, delays, or disruptions while we integrate the T-Mobile and MetroPCS businesses. The existence of one or more material weaknesses could result in errors in our financial statements, and substantial costs and resources may be required to rectify these or other internal control deficiencies. If we are unable to comply with the requirements of Section 404 in a timely manner or assert that our internal control over financial reporting is effective, investors may lose confidence in the accuracy and completeness of our financial reports and the trading price of the notes could be negatively affected, and we could become subject to investigations by the stock exchange on which our securities are listed, the SEC, or other regulatory authorities, which could require additional financial and management resources.

We have made significant changes to our corporate structure, strategy, and operations in effort to revitalize the business and effect change in our market position.

Over the last few years, our company has made significant corporate changes including: new executive leadership and changes in executive leadership responsibilities; new governance structures; call center consolidation; organizational restructuring, and changed methods of funding. Although these are designed to improve company performance, in some cases they insert additional business complexity, and thus are accompanied by associated risks to effective operations. For example, our management and other personnel may devote a substantial amount of time to these new initiatives, and such corporate changes may increase our legal and compliance costs and may make some activities more time-consuming and costly.

We rely on highly-skilled personnel throughout all levels of our business. Our business could be harmed if we are unable to retain or motivate key personnel, hire qualified personnel, or maintain our corporate culture.

We believe that our future success depends in substantial part on our ability to recruit, hire, motivate, develop, and retain talented and highly-skilled personnel. Achieving this objective may

S-30

be difficult due to many factors, including fluctuations in economic and industry conditions, competitors’ hiring practices, employee tolerance for the significant amount of change within and demands on our company and our industry, and the effectiveness of our compensation programs. If we do not succeed in retaining and motivating our existing key employees and in attracting new key personnel, we may be unable to meet our business plan and, as a result, our revenue growth and profitability may be materially adversely affected.

Risks related to legal, regulatory and governance matters

We operate throughout the United States, Puerto Rico, and the U.S. Virgin Islands, and as such are subject to regulatory and legislative action by applicable local, state and federal governmental entities, which may increase our costs of providing products or services, or require us to change our business operations, products, or services or subject us to material adverse impacts if we fail to comply with such regulations.

The FCC regulates the licensing, construction, modification, operation, ownership, sale, and interconnection of wireless communications systems, as do some state and local regulatory agencies. The FCC also reviews and in some cases restricts non-U.S. ownership of wireless communications systems. We cannot assure you that the FCC or any state or local agencies having jurisdiction over our business will not adopt regulations or take other enforcement or other actions that would adversely affect our business, impose new costs, or require changes in current or planned operations. We are subject to regulatory action by the FCC and other federal agencies, as well as judicial review and actions, on issues related to the wireless industry that include, but are not limited to: roaming, network outages, spectrum allocation and licensing, pole attachments, intercarrier compensation, Universal Service Fund (USF), net neutrality, special access, 911 services, consumer protection including cramming, bill shock, and handset unlocking, consumer privacy, and cybersecurity.

In addition, states are increasingly focused on the quality of service and support that wireless carriers provide to their customers and several agencies have proposed or enacted new and potentially burdensome regulations in this area. A number of state Public Utility Commissions and state legislatures have introduced proposals in recent years seeking to regulate carriers’ business practices. We also face potential investigations by, and inquiries from or actions by state Public Utility Commissions, and state Attorneys General. Further, we are subject to regulations in other aspects of our business, including handset financing. We also cannot assure you that Congress will not amend the Communications Act of 1934 as amended (the “Communications Act”), from which the FCC obtains its authority and which serves to limit state authority, or enact other legislation in a manner that could be adverse to our business. Enactment of additional state or federal regulations may increase our costs of providing services (including, through contributions to universal service programs, which may require us to subsidize our competitors) or require us to change our services. Failure to comply with applicable regulations could have a material adverse effect on our business, financial condition and results of operations.

Unfavorable outcomes of legal proceedings may adversely affect our business and financial condition.

We are regularly involved in a number of legal proceedings before various state and federal courts, the FCC, and state and local regulatory agencies. Such legal proceedings can be complex, costly, and highly disruptive to business operations by diverting the attention and energies of management and other key personnel. The assessment of the outcome of legal proceedings, including our potential liability, if any, is a highly subjective process that requires judgments

S-31

about future events that are not within our control. The outcome of litigation or other legal proceedings, including amounts ultimately received or paid upon settlement, may differ materially from amounts accrued in the 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, financial condition, operating results, or ability to do business.

We may be unable to protect our intellectual property.

We rely on a combination of patent, service mark, trademark, and trade secret laws and contractual restrictions to establish and protect our proprietary rights, all of which offer only limited protection. The steps we have taken to protect our intellectual property may not prevent the misappropriation of our proprietary rights. Moreover, others may independently develop processes and technologies that are competitive to ours. We cannot be sure that any legal actions against such infringers will be successful, even when our rights have been infringed. We cannot assure you that our pending patent applications will be granted or enforceable, or that the rights granted under any patent that may be issued will provide us with any competitive advantages. In addition, we cannot assure you that any trademark or service mark registrations will be issued with respect to pending or future applications or will provide adequate protection of our brands. We do not have insurance coverage for intellectual property losses, and as such, a charge for an anticipated settlement, or an adverse ruling awarding damages, represents unplanned loss events. Any of these factors could have a material adverse effect on our business, financial condition and results of operations. Furthermore, we could be subject to fines, forfeitures and other penalties (including, in extreme cases, revocation of our licenses) for failure to comply with FCC regulations, even if any such non-compliance was unintentional. The loss of any licenses, or any related fines or forfeitures, could adversely affect our business, results of operations and financial condition.

We use equipment, software, technology, and content in the operation of our business, which may subject us to third-party intellectual property claims and we may be adversely affected by litigation involving our suppliers.

We are a defendant in numerous intellectual property lawsuits, including patent infringement lawsuits, which exposes us to the risk of adverse financial impact either by way of significant settlement amounts or damage awards. As we adopt new technologies and new business systems, and provide customers with new products and/or services, we may face additional infringement claims. These claims could require us to cease certain activities or to cease selling relevant products and services. These claims can be time-consuming and costly to defend, and divert management resources. In addition to litigation directly involving our company, our vendors and suppliers can be threatened with patent litigation and/or subjected to the threat of disruption or blockage of sale, use, or importation of products, posing the risk of supply chain interruption to particular products and associated services exposing us to material adverse operational and financial impacts.

Our business may be impacted by new or changing tax laws or regulations and actions by federal, state, local or non-U.S. agencies, or how judicial authorities apply tax laws.

We calculate and remit surcharges, taxes and fees to numerous federal, state, local and non-U.S. jurisdictions in connection with the products and services we provide. These fees include federal USF fees and common carrier regulatory fees. In addition, many state and local governments impose various surcharges, taxes and fees on our sales and to our purchases of telecommunications

S-32

services from various carriers. In many cases, the applicability and method of calculating these surcharges, taxes and fees may be uncertain, and our calculation, assessment and remittance of these amounts may be contested. In the event that we have incorrectly assessed and remitted amounts that were due, we could be subject to fines and penalties, which could materially impact our financial condition. In the event that federal, state, local and/or non-U.S. municipalities were to significantly increase taxes and regulatory fees on our services or seek to impose new ones, it could have a material adverse effect on our margins and financial and operational results.

Our wireless licenses are subject to renewal and may be revoked in the event that we violate applicable laws.

Our existing wireless licenses are subject to renewal upon the expiration of the 10-year or 15-year period for which they are granted. Historically, the FCC has approved our license renewal applications. However, the Communications Act provides that licenses may be revoked for cause and license renewal applications denied if the FCC determines that a renewal would not serve the public interest. In addition, our licenses are subject to our compliance with the terms set forth in the agreement pertaining to national security among Deutsche Telekom, the Federal Bureau of Investigation, the Department of Justice, the Department of Homeland Security and the Company. If we fail to timely file to renew any wireless license, or fail to meet any regulatory requirements for renewal, including construction and substantial service requirements, we could be denied a license renewal. Many of our wireless licenses are subject to interim or final construction requirements and there is no guarantee that the FCC will find our construction, or the construction of prior licensees, sufficient to meet the build-out or renewal requirements. The FCC has pending a rulemaking proceeding to reevaluate, among other things, its wireless license renewal showings and standards and may in this or other proceedings promulgate changes or additional substantial requirements or conditions to its renewal rules, including revising license build out requirements. Accordingly, we cannot assure you that the FCC will renew our wireless licenses upon their expiration. If any of our wireless licenses were to be revoked or not renewed upon expiration, we would not be permitted to provide services under that license, which could have a material adverse effect on our business, results of operations, and financial condition.

Our business could be adversely affected by findings of product liability for health/safety risks from wireless devices and transmission equipment, as well as by changes to regulations/RF emission standards.

We do not manufacture devices or other equipment sold by us, and we depend on our suppliers to provide defect-free and safe equipment. Suppliers are required by applicable law to manufacture their devices to meet certain governmentally imposed safety criteria. However, even if the devices we sell meet the regulatory safety criteria, we could be held liable with the equipment manufacturers and suppliers for any harm caused by products we sell if such products are later found to have design or manufacturing defects. We generally seek to enter into indemnification agreements with the manufacturers who supply us with devices to protect us from losses associated with product liability, but we cannot guarantee that we will be fully protected against all losses associated with a product that is found to be defective.

Allegations have been made that the use of wireless handsets and wireless transmission equipment, such as cell towers, may be linked to various health concerns, including cancer and brain tumors. Lawsuits have been filed against manufacturers and carriers in the industry claiming damages for alleged health problems arising from the use of wireless handsets. In addition, the FCC recently indicated that it plans to gather additional data regarding wireless

S-33

handset emissions to update its assessment of this issue. The media has also reported incidents of handset battery malfunction, including reports of batteries that have overheated. These allegations may lead to changes in regulatory standards. There have also been other allegations regarding wireless technology, including allegations that wireless handset emissions may interfere with various electronic medical devices (including hearing aids and pacemakers), airbags, and anti-lock brakes.

Additionally, there are safety risks associated with the use of wireless devices while operating vehicles or equipment. Concerns over any of these risks and the effect of any legislation, rules or regulations that have been and may be adopted in response to these risks could limit our ability to sell our wireless services.

We are controlled by Deutsche Telekom, whose interests may differ from the interests of our other stakeholders.

Deutsche Telekom beneficially owns and possesses voting power over approximately 74% of the fully diluted shares of our common stock. Through its control of the voting power of our common stock and the rights granted to Deutsche Telekom in our certificate of incorporation and the Stockholder’s Agreement, Deutsche Telekom controls the election of a majority of our directors and all other matters requiring the approval of our stockholders. By virtue of Deutsche Telekom’s voting control, we are a “controlled company,” as defined in the New York Stock Exchange, or NYSE, listing rules, and are not subject to NYSE requirements that would otherwise require us to have a majority of independent directors, a nominating committee composed solely of independent directors, or a compensation committee composed solely of independent directors.

In addition, our certificate of incorporation and the Stockholder’s Agreement restrict us from taking certain actions without Deutsche Telekom’s prior written consent as long as Deutsche Telekom beneficially owns 30% or more of the outstanding shares of our common stock, including the incurrence of debt (excluding certain permitted debt) if our consolidated ratio of debt to cash flow for the most recently ended four full fiscal quarters for which financial statements are available would exceed 5.25 to 1.0 on a pro forma basis, the acquisition of any business, debt or equity interests, operations or assets of any person for consideration in excess of $1 billion, the sale of any of our or our subsidiaries’ divisions, businesses, operations or equity interests for consideration in excess of $1 billion, any change in the size of our board of directors, the issuances of equity securities in excess of 10% of our outstanding shares or to repurchase debt held by Deutsche Telekom, the repurchase or redemption of equity securities or the declaration of extraordinary or in-kind dividends or distributions other than on a pro rata basis, or the termination or hiring of our chief executive officer. These restrictions could prevent us from taking actions that our board of directors may otherwise determine are in the best interests of the Company and our stockholders or that may be in the best interests of our other stakeholders.

Deutsche Telekom effectively has control over all matters submitted to our stockholders for approval, including the election or removal of directors, changes to our certificate of incorporation, a sale or merger of our company and other transactions requiring stockholder approval under Delaware law. Deutsche Telekom may have strategic, financial, or other interests different from our other stakeholders, including as the holder of a substantial amount of our indebtedness, and may make decisions adverse to the interests of our other stakeholders.

S-34

Management will have broad discretion as to the use of the proceeds from this offering, and we may not use the proceeds effectively.

Our management will have broad discretion in the application of the net proceeds from this offering and could spend the proceeds in ways that do not improve our results of operations or enhance the value of our common stock. Our failure to apply these funds effectively could have a material adverse effect on our business, financial condition and results of operations and cause the price of our common stock to decline.

Our stockholder rights plan could prevent a change in control of our Company in instances in which some stockholders may believe a change in control is in their best interests.

We have a stockholder rights plan (the “Rights Plan”) in effect. The Rights Plan will cause substantial dilution to a person or group that attempts to acquire our Company on terms that our board of directors does not believe are in our and our stockholders’ best interest. The Rights Plan is intended to protect stockholders in the event of an unfair or coercive offer to acquire the Company and to provide our board of directors with adequate time to evaluate unsolicited offers. The Rights Plan may prevent or make takeovers or unsolicited corporate transactions with respect to our Company more difficult, even if stockholders may consider such transactions favorable, possibly including transactions in which stockholders might otherwise receive a premium for their shares.

S-35

Use of proceeds

We estimate that the net proceeds from the sale of the notes in this offering will be approximately $         million, after deducting underwriting discounts and commissions and estimated offering expenses payable by us.

We expect to use the net proceeds from this offering for general corporate purposes, including making capital investments, enhancing financial flexibility and opportunistically acquiring additional spectrum. As of the date of this prospectus supplement, we cannot specify with certainty all of the particular uses for the net proceeds to us from this offering. Accordingly, our management will have broad discretion over the use of the net proceeds from this offering. Because of the importance of acquiring additional spectrum to our efforts to expand and improve our network, we may use the net proceeds, or a portion thereof, to acquire spectrum. We routinely evaluate spectrum acquisition opportunities, including both government auctions and private transactions. Although we do not intend to participate in the FCC’s upcoming auction of 1900 MHz PCS H block spectrum, we are currently considering an acquisition of spectrum from a private party. If we reach agreement to acquire such spectrum, we anticipate that a portion of the net proceeds of this offering will be used to finance such acquisition.

Unaudited pro forma condensed combined financial information

The following unaudited pro forma condensed combined financial information presents the unaudited pro forma condensed combined statements of operations based upon the combined historical financial statements of T-Mobile USA and MetroPCS, after giving effect to the Business Combination Transaction and adjustments described in the accompanying notes. In accordance with Article 11 of Regulation S-X (“Article 11”), a pro forma balance sheet is not required as the transaction has already been reflected in the unaudited September 30, 2013 balance sheet of the T-Mobile US, Inc.

The transaction is accounted for as a reverse acquisition under the acquisition method of accounting, which requires determination of the accounting acquirer. The accounting guidance for business combinations, Accounting Standards Codification 805, provides that in identifying the acquiring entity in a combination effected through an exchange of equity interests, all pertinent facts and circumstances must be considered, including: the relative voting rights of the stockholders of the constituent companies in the combined company, the existence of a large minority voting interest in the combined entity if no other owner or organized group of owners has a significant voting interest, the composition of the board of directors and senior management of the combined company, the relative size of each company and the terms of the exchange of equity securities in the business combination, including payment of any premium.

Because T-Mobile USA’s indirect stockholder, Deutsche Telekom, is entitled to designate the majority of the board of directors of the combined company, MetroPCS stockholders received a cash payment and Deutsche Telekom received a majority of the equity securities and voting rights of the combined company, T-Mobile USA is considered to be the acquirer of MetroPCS for accounting purposes. This means that the Company allocated the purchase price to the fair value of MetroPCS’ assets and liabilities as of the acquisition date, with any excess purchase price being recorded as goodwill.

The unaudited pro forma condensed combined statements of operations for the year ended December 31, 2012 and the nine months ended September 30, 2013 reflect the transaction as if it had occurred on January 1, 2012, the beginning of the earliest period presented.

The unaudited pro forma condensed combined financial information should be read in conjunction with the audited and unaudited historical financial statements of each of T-Mobile USA and MetroPCS and the notes thereto, as well as the disclosures contained in each company’s Management’s Discussion and Analysis of Financial Condition and Results of Operations. Additional information about the basis of presentation of this information is provided in Note 1 hereto.

The unaudited pro forma condensed combined financial information was prepared in accordance with Article 11. The unaudited pro forma adjustments reflecting the transaction have been prepared in accordance with business combination accounting guidance as provided in Accounting Standards Codification 805, and reflect the preliminary allocation of the purchase price to the acquired assets and liabilities based upon the preliminary estimate of fair values, using the assumptions set forth in the notes to the unaudited pro forma condensed combined financial information.

The unaudited pro forma condensed combined financial information is provided for informational purposes only and is not necessarily indicative of the operating results that would have occurred if the transaction had been completed as of the dates set forth above, nor is it

S-39

indicative of the future results of the combined company. In connection with the pro forma financial information, the Company allocated the purchase price using its best estimates of fair value. The pro forma acquisition price adjustments are preliminary and subject to further adjustments as additional information become available and as additional analyses are performed. There can be no assurances that the final valuations will not result in material changes to the preliminary estimated purchase price allocation. The unaudited pro forma condensed combined financial information also does not give effect to the potential impact of current financial conditions, any anticipated synergies, operating efficiencies or cost savings that may result from the transaction or any integration costs. Furthermore, the unaudited pro forma condensed combined statements of operations do not include certain nonrecurring charges and the related tax effects which result directly from the transaction as described in the notes to the unaudited pro forma condensed combined financial information.

1. Basis of presentation

The historical financial information has been adjusted to give pro forma effect to events that are (i) directly attributable to the transaction, (ii) factually supportable, and (iii) expected to have a continuing impact on the combined results. The pro forma adjustments are preliminary and based on estimates of the fair value and useful lives of the assets acquired and liabilities assumed and have been prepared to illustrate the estimated effect of the transaction and certain other adjustments. The final determination of the purchase price allocation will be based on the fair values of assets acquired and liabilities assumed as of April 30, 2013 (the “Acquisition Date”), the date the transaction closed.

T-Mobile USA’s historical results are derived from T-Mobile USA’s audited consolidated statement of comprehensive income for the year ended December 31, 2012, and unaudited condensed consolidated statement of comprehensive income for the nine months ended September 30, 2013 under accounting principles generally accepted in the United States of America (“GAAP”). MetroPCS’ historical results are derived from the audited consolidated statement of comprehensive income for the year ended December 31, 2012, the unaudited condensed consolidated statement of comprehensive income for the three months ended March 31, 2013, and the unaudited condensed consolidated statement of comprehensive income for the one month ended April 30, 2013 under GAAP.

Significant accounting policies

The accounting policies used in the preparation of these unaudited pro forma condensed combined financial information are those set out in T-Mobile USA’s audited financial statements as of December 31, 2012 and MetroPCS’ audited financial statements as of December 31, 2012. Management has determined that no significant adjustments are necessary to conform MetroPCS’ financial statements to the accounting policies used by T-Mobile USA in the preparation of the unaudited pro forma condensed combined financial information.

Description of transaction

On October 3, 2012, MetroPCS entered into the Business Combination Agreement, by and among Deutsche Telekom, T-Mobile Global Zwischenholding GmbH, a Gesellschaft mit beschränkter Haftung organized in Germany and a direct wholly-owned subsidiary of Deutsche Telekom (“Global”), T-Mobile Global Holding GmbH, a Gesellschaft mit beschränkter Haftung organized in Germany and a direct wholly-owned subsidiary of Deutsche Telekom (“Holding”), Global, Holding, T-Mobile USA and MetroPCS, which was subsequently amended on April 14, 2013.

On the Acquisition Date, MetroPCS (i) effected a recapitalization that included a reverse stock split of the MetroPCS common stock, which represented thereafter one-half of a share of MetroPCS common stock; (ii) as part of the recapitalization, distributed a cash payment in an amount equal to $1.5 billion (or approximately $4.05 per share pre-reverse stock split), without interest, in the aggregate to the record holders of MetroPCS common stock immediately following the effective time of the reverse stock split; and (iii) issued and delivered to Holding or its designee shares of MetroPCS common stock equal to 74% of the fully-diluted shares of MetroPCS common stock outstanding immediately following the cash payment, and Holding delivered to MetroPCS all of the shares of capital stock of T-Mobile USA.

S-43

The pro forma adjustments take into consideration the senior unsecured notes in an aggregate principal amount of $14.7 billion, which were issued or offered as follows:

• $11.2 billion notes were issued by T-Mobile USA to Deutsche Telekom or its subsidiaries to refinance certain intercompany indebtedness owed by T-Mobile USA and its subsidiaries to Deutsche Telekom and its subsidiaries (excluding T-Mobile USA and its subsidiaries).

• $3.5 billion notes were issued by MetroPCS Wireless, Inc. (“Wireless”), a wholly owned subsidiary of MetroPCS to third party investors of which the net proceeds were used by MetroPCS to refinance the Wireless existing senior credit facility and for general corporate purposes.

As of the date of this prospectus supplement, MetroPCS and T-Mobile USA had incurred approximately $74.4 million of transaction costs. An adjustment of $49.2 million and $25.2 million has been reflected in the unaudited pro forma condensed combined statements of operations for the nine months ended September 30, 2013 and for the year ended December 31, 2012, respectively, related to transaction costs as these are nonrecurring charges, which are to be excluded in accordance with Article 11. The transaction costs of $74.4 million exclude financing fees related to $3.5 billion notes, which were approximately $40.0 million, as well as an insignificant amount of financing fees related to the $11.2 billion notes.

Certain other nonrecurring charges have been excluded from the unaudited pro forma condensed combined statements of operations in accordance with Article 11. The excluded nonrecurring charges related to the acceleration of MetroPCS’ share based payments and the related severance and change in control payments. An adjustment of $89.4 million has been reflected in the unaudited pro forma condensed combined statement of operations for the nine months ended September 30, 2013 in connection with the estimated charge relating to the acceleration of MetroPCS’ share based payments incurred by MetroPCS prior to the combination of the two companies. An adjustment of $67.0 million has been reflected in the unaudited pro forma condensed combined statement of operations for the nine months ended September 30, 2013 relating to change in control payments to MetroPCS’ employees.

2. Calculation of purchase consideration

The purchase consideration in a reverse acquisition is determined with reference to the value of equity that the accounting acquirer (in this case, T-Mobile USA, the legal subsidiary) has issued to the owners of the accounting acquiree (MetroPCS, the legal parent) to give them the same percentage interest in the combined entity. The fair value of MetroPCS common stock is based on the closing stock price on the Acquisition Date of $11.84 per share. The Company expects that the allocation of the purchase price will be finalized within twelve months after the Acquisition Date.

The purchase price is calculated as follows:

(in millions, except share and per share amounts)	Purchase consideration
Number of MetroPCS shares outstanding(i)		370,457,300
MetroPCS common stock price(ii)	$	7.79
Fair value of MetroPCS shares	$	2,886
Fair value of stock options(iii)		84
Cash consideration paid to stock option holders(iii)		1
Estimated purchase price	$	2,971

S-44

(i) Number of shares of MetroPCS common stock issued and outstanding as of April 30, 2013, including MetroPCS unvested restricted stock, which immediately vested upon closing.

(ii) Closing price of MetroPCS common stock on the New York Stock Exchange on April 30, 2013 of $11.84 per share adjusted by the $4.05 per share impact of the $1.5 billion cash payment. The cash payment was a return of capital, made as part of the recapitalization to the MetroPCS stockholders prior to the stock issuance to Holding or its designee. MetroPCS made the $1.5 billion cash payment (or approximately $4.05 per share pre-reverse stock split), without interest, in the aggregate to the record holders of MetroPCS common stock immediately following the effective time of the reverse stock split.

(iii) Pursuant to the Business Combination Agreement, unvested equity awards immediately vested and stock option holders received stock options of the combined entity on the Acquisition Date, subject to stockholder’s right to cash redemption for options in which the exercise price was less than the average closing price for the five days preceding the closing (“in-the-money options”). Stock options with low exercise prices, as defined in the Business Combination Agreement, were canceled in exchange for cash consideration. Therefore, the fair value of stock options includes all stock options outstanding, adjusted for those options meeting the definition of low exercise price and elections made by the option holders with the in-the-money stock options, which were subject to cash payment.

Preliminary purchase price allocation

Under the acquisition method of accounting, the identifiable assets acquired and liabilities assumed of MetroPCS are recorded at the acquisition date fair values and added to those of T-Mobile USA. The pro forma adjustments are preliminary and based on estimates of the fair value and useful lives of the assets acquired and liabilities assumed as of April 30, 2013 and have been prepared to illustrate the estimated effect of the transaction. The allocation is dependent upon certain valuation and other studies that have not yet been completed. Accordingly, the pro forma purchase price allocation is subject to further adjustments as additional information becomes available and as additional analyses and final valuations are completed. There can be no assurances that these additional analyses and final valuations will not result in significant changes to the estimates of fair value set forth below.

The following table sets forth a preliminary allocation of the estimated purchase consideration to the identifiable tangible and intangible assets acquired and liabilities assumed of MetroPCS, with the excess recorded as goodwill:

(in millions)	Preliminary fair value
Assets
Cash and cash equivalents	$	2,144
Accounts receivable, net		98
Inventory		171
Other current assets		240
Property and equipment		1,475
Spectrum licenses		3,818
Other intangible assets		1,376
Other assets		10
Total assets acquired		9,332
Liabilities and Stockholders’ Equity
Accounts payable and accrued liabilities		475
Deferred revenues		187
Other current liabilities		15
Deferred tax liabilities		735
Long-term debt		6,277
Other long-term liabilities		355
Total liabilities assumed		8,044
Net identifiable assets acquired		1,288
Goodwill		1,683
Net assets acquired	$	2,971

S-45

Acquisition Date fair values for net property and equipment were calculated utilizing a cost approach that estimates the fair value of property and equipment needed to replace the functionality provided by the existing property and equipment. The estimated Acquisition Date fair values of property and equipment reflect a significant decrease in the carrying value of MetroPCS’ property and equipment due to advances in telecommunications equipment technology allowing a market participant to utilize a smaller quantity of property and equipment in a wireless network to achieve the same functionality. Additionally, MetroPCS’ cell sites are concentrated in dense urban areas, where a market participant would have significant overlapping coverage, thus the Acquisition Date fair value is impacted by the accelerated decommissioning of a large number of cell sites.

3. Notes to unaudited pro forma condensed combined statements of operations

(a) Represents adjustments to record depreciation and amortization expense related to the reduced basis of property and equipment by $2.7 billion, which have been recorded at estimated fair value on a pro forma basis and will be depreciated and amortized over the estimated remaining useful lives on a straight-line basis utilizing T-Mobile USA’s useful life assumptions as provided for each class of property and equipment in the table below. The useful life assumptions differ from MetroPCS’ property and equipment useful life assumptions because each company’s assumptions are based on its own historical experience with similar assets and its own intended use for the assets, while also taking into account anticipated technological or other changes. The value of each is noted below:

(in millions)	Useful life		Adjusted basis
Buildings and improvements		Up to 20 years	$	14
Wireless communications systems		Up to 15 years		960
Capitalized software		Up to 3 years		162
Equipment and furniture		Up to 5 years		268
Construction in progress				71
Property and equipment, net			$	1,475

S-46

Historical depreciation and amortization expense was adjusted for the fair value adjustment decreasing the basis of property and equipment, as well as the useful life assumption changes. The fair value adjustment to basis most significantly impacts certain network-related equipment and construction costs in wireless communication systems. Historically reported depreciation was reduced in part due to the asset basis adjustment, in particular to network equipment representing 3G or third generation technologies as well as redundant macro cell sites. Offsetting the impact of the adjustment to basis is an increase in depreciation due to generally shorter T-Mobile USA useful life assumptions as introduced by differences in policy as well as the intended use of the property and equipment. The approximate impact of each is illustrated below:

(in millions)	Year ended December 31, 2012			Nine months ended September 30, 2013
Historical depreciation and amortization	$	641		$	229
Adjustment related to:
Asset basis of property and equipment, net		(400	)		(144	)
Useful life assumptions		223			70
Pro forma adjustment		(177	)		(74	)
Adjusted MetroPCS depreciation and amortization expense	$	464		$	155

(b) Represents adjustment to record amortization expense related to other identifiable intangible assets. These identifiable intangible assets include:

• Subscriber relationships ($1,104 million)—Represents relationships with U.S. domestic subscribers that are expected to have an estimated useful life of approximately six years. The amount is amortized using the accelerated depreciation method.

• Trade names ($233 million)—Represents the MetroPCS brand that has been estimated to have a useful life of approximately eight years. The amount is amortized using the straight-line method.

Indefinite lived intangible assets, including spectrum licenses and goodwill, are not subject to amortization but will be tested for impairment annually or more frequently if events or changes in circumstances indicate that the assets might be impaired.

(c) Represents adjustment to income tax expense as a result of the tax impact on the pro forma adjustments. Tax rate of 37.5% has been utilized, which reflects the tax rate of the combined company, to compute the income tax expense related to the pro forma adjustments on the pro forma condensed combined statements of operations as follows:

(in millions)	Year ended December 31, 2012			Nine months ended September 30, 2013
Pro forma adjustments	$	(339	)	$	143
Statutory rate		37.5%			37.5%
Income tax benefit (expense)	$	127		$	(54	)

S-47

(d) Represents the income (loss) per share, taking into consideration the pro forma weighted average shares outstanding calculated including the acceleration of the vesting of the restricted stock, applying the reverse stock split and the issuance of common stock equal to 74% of the fully-diluted shares of common stock outstanding for the year ended December 31, 2012.

	Year ended December 31, 2012
Weighted average shares outstanding		363,449,061
Unvested restricted shares		4,421,102
		367,870,163
Reverse 1:2 stock split		0.50
		183,935,081
Issuance of shares to Deutsche Telekom		535,286,077
Pro forma basic and diluted weighted average shares		719,221,158

(e) Represents the amortization of the net unfavorable lease adjustment recorded under purchase accounting at the Acquisition Date. The net unfavorable lease amount recorded is amortized over the estimated average useful life of the underlying leases.

(f) Represents reclassification of certain revenue and expense line items of MetroPCS’ audited consolidated statement of comprehensive income for the year ended December 31, 2012, the unaudited interim condensed consolidated statement of comprehensive income for the three months ended March 31, 2013, and the unaudited condensed consolidated statement of comprehensive income for the one month ended April 30, 2013 to conform with T-Mobile USA’s presentation of consolidated statement of comprehensive income for the year ended December 31, 2012, and the unaudited interim condensed consolidated statement of comprehensive income for the nine months ended September 30, 2013.

4. Financing agreements

As described in Note 1, the transaction was financed in part by the issuance of senior unsecured notes by T-Mobile USA and Wireless for amounts of $11.2 billion senior notes and $3.5 billion senior notes, respectively.

The weighted average interest rates for the $11.2 billion senior notes are 6.62% and 5.73% for the permanent notes ($5.6 billion) and reset notes ($5.6 billion), respectively with maturity dates which range from 2019 to 2023. As a result of T-Mobile USA’s exchange of indebtedness and settlement of the related currency and interest rate swaps, the pro forma adjustments reflect the adjustment to historical interest expense to record the estimated pro forma interest expense under the senior notes of $691.7 million and $518.8 million for the year ended December 31, 2012 and for the nine months ended September 30, 2013, respectively.

The pro forma adjustments also reflect the issuance by Wireless of $3.5 billion of fixed-rate senior unsecured notes to third-party investors on March 19, 2013 (the “Wireless Notes”), a portion of which was used to repay the pre-existing $2.4 billion senior secured credit facility. The $3.5 billion of Wireless Notes were issued in two tranches, consisting of $1.75 billion aggregate principal amount of 6.250% Senior Notes due 2021 and $1.75 billion aggregate principal amount of

S-48

6.625% Senior Notes due 2023. The pro forma adjustments reflect the estimated incremental pro forma interest expense of $101.2 million and $12.3 million for the year ended December 31, 2012 and for the nine months ended September 30, 2013, respectively.

5. Tower transaction

On November 30, 2012, T-Mobile USA conveyed to Crown Castle International Corp. (“CCI”) the exclusive right to manage and operate approximately 7,100 T-Mobile USA owned wireless communication tower sites (the “Tower Transaction”). The adjustments in the unaudited pro forma condensed combined statement of operations assume the Tower Transaction occurred on January 1, 2012, resulting in approximately $28.0 million in incremental revenue from implied sublease to third parties of the portion of tower sites not leased back by T-Mobile USA and approximately $174.0 million in incremental interest expense related to the financial liability for the year ended December 31, 2012. There are no adjustments for the unaudited pro forma condensed combined statement operations for the nine months ended September 30, 2013 as the Tower Transaction was closed in 2012.

For purposes of the unaudited pro forma condensed combined financial information, revenues from the implied sublease to third parties were determined based on the excess of third party revenues projected for the period after close of the transaction over revenues reflected in the historical financial statements. The interest rate used for purposes of the unaudited pro forma condensed combined financial information to calculate imputed interest expense related to the financial liability was approximately 8%, based upon the effective interest rate implicit in the transaction. For further information concerning the Tower Transaction, see Note 4 to the audited consolidated financial statements of T-Mobile USA for the year ended December 31, 2012.

6. Trademark license

The Company and Deutsche Telekom entered into a trademark license in connection with the completion of the transaction, under which the Company is obligated to pay Deutsche Telekom a royalty in an amount equal to 0.25% of the net revenue generated by products and services sold by the combined company under the licensed trademarks. Under the trademark license, products and services sold by the combined company under the MetroPCS brand or trademarks owned by the combined company are excluded from the royalty calculation so long as they are not used in conjunction with the trademarks subject to the trademark license.

On the fifth anniversary of the trademark license, the Company and Deutsche Telekom have agreed to adjust the royalty rate based on the then average commercial royalty rate found under similar licenses for trademarks in the field of wireless telecommunication, broadband and information products and services in the territory through a binding benchmarking process. The adjustment of the royalty rate will depend on the then average commercial royalty rates charged in the field of wireless telecommunication, broadband and information products and services in the territory covered by the trademark license, which can be affected by a number of factors, including the royalty rate charged by others in the relevant field and the relative value of the T-Mobile USA trademark. Royalty rates vary considerably, are dependent on a number of factors which cannot be known at this time, and can change year-by-year, making it difficult at this time to determine any definitive estimate of what the current average commercial royalty rate will be in five years.

Within the unaudited pro forma condensed combined statements of operations, no pro forma adjustments are presented for the trademark license because it is expected that the expenses

S-49

associated with the trademark license will be substantially the same as in the T-Mobile USA consolidated audited financial statements for the year ended December 31, 2012 and in the T-Mobile USA unaudited condensed consolidated financial statements for the nine months ended September 30, 2013. The financial statements of T-Mobile USA reflect royalty expenses from an existing licensing agreement between Deutsche Telekom and T-Mobile USA which management believes approximate the expenses under the new trademark license. Additionally, the Company expects to continue to sell MetroPCS services and products under the MetroPCS brand or trademarks and not use such MetroPCS brand or trademarks in conjunction with the trademarks subject to the licensing agreements; and, therefore, the combined company is not expected to incur royalty expenses on net revenues generated from the sale of MetroPCS branded services and products.

Business

Business overview

T-Mobile is a national provider of mobile communications services capable of reaching over 280 million Americans. Our objective is to be the simpler choice for a better mobile experience. Our intent is to bring this proposition to life across all our brands, including T-Mobile, MetroPCS, and GoSmart, and across our major customer base of retail, wholesale and business (B2B) consumers.

We generate revenue by offering affordable postpaid and prepaid wireless voice, messaging and data services, as well as mobile broadband and wholesale wireless services. We provided service to approximately 45 million customers through our nationwide network as of September 30, 2013. We also generate revenues by offering a wide selection of wireless handsets and accessories, including smartphones, wireless-enabled computers such as notebooks and tablets, and data cards which are manufactured by various suppliers. Our most significant expenses are related to acquiring and retaining customers, maintaining and expanding our network, and compensating employees.

Business combination with MetroPCS

On April 30, 2013, the business combination of T-Mobile USA and MetroPCS was completed. Under the terms of the Business Combination Agreement, Deutsche Telekom received approximately 74% of the fully-diluted shares of common stock of the combined company in exchange for its transfer of all of T-Mobile USA’s common stock. This transaction was consummated to provide us with expanded scale, spectrum, and financial resources to compete aggressively with other, larger U.S. wireless carriers.

Competitive strengths

We believe the following strengths foster our ability to compete against our principal wireless competitors:

• Value leadership in wireless.    We are a leading value-oriented wireless carrier in the United States and the third largest provider of prepaid service plans as measured by subscribers.

• Spectrum assets.    As of September 30, 2013, we hold licenses for wireless spectrum suitable for wireless broadband mobile services (including both HSPA+ and LTE) covering a population of approximately 280 million people in the United States. As of September 30, 2013, we have an average of approximately 74 MHz of spectrum in the top 100 major metropolitan areas and have an average of approximately 77 MHz of spectrum in the top 25 major metropolitan areas. Our aggregate spectrum position is expected to enable contiguous 20x20 MHz channels for LTE deployment in many major metropolitan areas, which is expected to improve capacity to support our product offerings by increasing the data speeds available to our customers.

• Advanced nationwide high-speed network.    As of September 30, 2013, our LTE network covered a population of approximately 200 million people in the United States. We believe the combination of our spectrum position and advanced network technology will provide us with a high-capacity, high-speed network. Upon completion of the migration of the MetroPCS customer base, we expect to have approximately 55,000 equivalent cell sites, including

S-53

approximately 1,500 MetroPCS macro sites and certain DAS network nodes retained from the MetroPCS network. Approximately 35,000 sites are planned to be enhanced over three years with multi-mode radios, tower-top electronics, and new antennas. This will allow for more robust coverage in buildings and at the edge of coverage areas and will allow for greater data capacity, which we believe will enhance the customer experience for our subscriber base.

• Seasoned executive leadership.    We have a seasoned executive leadership team with significant industry expertise, led by John Legere, our President and Chief Executive Officer. Mr. Legere has over 32 years of experience in the U.S. and global telecommunications and technology industries. J. Braxton Carter, formerly MetroPCS’ Vice Chairman and Chief Financial Officer, serves as our Chief Financial Officer. Our board of directors includes current and former executives of AT&T, Dell, Rockwell International Corporation and Madison Dearborn Partners, LLC, and brings extensive experience in operations, finance, governance and corporate strategy.

Business strategy

We continue to aggressively pursue our strategy to reposition T-Mobile and return the Company to growth. Our strategy focuses on the following elements:

• Un-carrier value proposition.    We plan to extend our position as the leader in delivering distinctive value for consumers in all customer segments. We believe the launches of Un-carrier phases 1 and 2 have been successful, as evidenced by our strong customer growth momentum. Simple Choice plans, launched in March 2013 as phase 1 of our Un-carrier value proposition, eliminate annual service contracts and provide customers with affordable rate plans without the complexity of caps and overage charges. Customers on Simple Choice plans can purchase the most popular smartphones and if qualified, pay for them in affordable interest-free monthly installments. Modernization of the network and introduction of the Apple^® iPhone^® in the second quarter of 2013 further repositioned T-Mobile as a provider of dependable high-speed service with a full range of desirable handsets and devices. In July 2013, we announced phase 2 of our Un-carrier value proposition, JUMP!™, which enables participating subscribers to upgrade their eligible handset up to twice a year upon completion of an initial six-month enrollment period. In October 2013, we unveiled phase 3 of our Un-carrier value proposition, which provides our customers reduced United States to International calling rates and roaming fees, and free data roaming while traveling abroad in over 100 countries. In addition, in November 2013, we began to offer the Apple^® iPad^® Air and iPad^® mini.

• Network modernization.    We are currently in the process of rapidly upgrading our network to modernize the 4G network, improve coverage, align spectrum bands with other key players in the U.S. market and deploy nationwide 4G LTE services in 2013. The timing of the launch of 4G LTE allows us to take advantage of the latest and most advanced 4G LTE technology infrastructure, improving the overall capacity and performance of our 4G network, while optimizing spectrum resources. In October 2013, we announced that we have exceeded our 2013 targets for 4G LTE network coverage, by delivering 4G LTE to more than 200 million people in 254 metro areas and a goal to deploy 10+ 10 MHz 4G LTE in 24 of the Top 25 metro areas by year end (and 40 of the Top 50 metro areas). Additionally, the migration of MetroPCS brand legacy CDMA customers onto T-Mobile’s 4G HSPA+ and LTE network is ahead of schedule, providing faster network performance for MetroPCS customers with compatible handsets. We expect the migration to be complete by the end of 2015.

S-54

• Multi-segment focus.    We plan to continue to operate in multiple customer market segments to accelerate growth. The addition of the flagship MetroPCS brand to the T-Mobile portfolio increased our ability to serve the full breadth of the wireless market. We expect to continue to accelerate the growth of the MetroPCS brand by expanding into new geographic regions, through the end of 2013 and continuing through 2014. Recently, we introduced the Simple Choice value proposition to our prepaid and B2B customers as well, so that prepaid customers and businesses can leverage the benefits of the Simple Choice plans. Additionally, we expect to continue to expand our wholesale business through MVNOs and other wholesale relationships where our spectrum depth, available network capacity and GSM technology base help secure profitable wholesale customers.

• Aligned cost structure.    We continue to pursue a low-cost business operating model to drive cost savings, which can be reinvested in the business. These cost programs are on-going as we continue to work to simplify our business and drive operational efficiencies and cost savings in areas such as network optimization, customer roaming, customer service, improved customer collection rates and better management of customer acquisition and retention costs. A portion of savings have been, and will continue to be, reinvested into customer acquisition programs.

Services and products

T-Mobile provides wireless communication services nationwide through a variety of service plan options. These include our Value and Simple Choice plans, which allow customers to subscribe for wireless services separately from, or without purchase of, or upfront payment for, a handset.

We introduced our Simple Choice plans as part of our Un-carrier value proposition in the first quarter of 2013. Simple Choice plans eliminate annual service contracts and simplify the lineup of consumer rate plans to one affordable plan for unlimited talk, text and web service with the option to add data services. Depending on their credit profiles, customers are qualified either for postpaid service, where they generally pay after incurring service, or prepaid service, where they generally pay in advance.

Customers on our Simple Choice or similar plans benefit from reduced monthly service charges and can choose whether to use their own compatible handset on our network or purchase a handset from us or one of our dealers. Depending on their credit profile, qualifying customers who purchase their handset from us have the option of financing a portion of the purchase price at the point-of-sale over an installment period. Our Value and Simple Choice plans result in increased equipment revenue for each handset sold compared to traditional bundled price plans that typically offer a significant handset discount but involve higher monthly service charges. Our Value and Simple Choice plans also result in increased net income during the period of sale while monthly service revenues are lower over the service period.

In July 2013, we launched phase 2 of our Un-carrier value proposition, Just Upgrade My Phone (“JUMP!™”), under which qualifying customers who finance their initial handset purchase using our Equipment Installment Plan (“EIP”) and enroll in JUMP!™ can upgrade their handset up to twice a year, following completion of an initial six-month enrollment period, and receive a credit for their outstanding EIP balance provided they trade in their used handset to purchase a new handset from us.

We offer services, handsets and accessories directly to consumers through our owned and operated retail stores, as well as through our websites (www.T-Mobile.com and www.MetroPCS.com). The

S-55

information on our website is not part of this prospectus supplement. In addition, we sell handsets to dealers and other third party distributors for resale through independent third party retail outlets and a variety of third party websites.

Since the Business Combination Transaction, we have achieved significant integration milestones incorporating the MetroPCS business. We have launched HSPA+/LTE devices in multiple historical MetroPCS markets and have combined our 4G LTE spectrum in Las Vegas. In addition, we have extended the geographic presence of the MetroPCS distribution to 15 additional markets and have launched more than 1,300 distribution points in these new markets at the end of the quarter ended September 30, 2013. We expect to launch the MetroPCS brand in another 15 markets in November 2013.

Service areas

We provide service in all major metropolitan areas and will have addressable Points of Presence (“POPs”) coverage of approximately 280 million:

Upon completion of the migration of the MetroPCS customer base, we expect to have approximately 55,000 equivalent cell sites, including approximately 1,500 MetroPCS macro sites and certain DAS network nodes retained from the MetroPCS network. As part of the business combination, we are in the process of decommissioning redundant cell sites and the MetroPCS CDMA network, while also integrating select MetroPCS assets (primarily DAS nodes) in certain metropolitan areas into the overall network.

In October 2013, we purchased 10 MHz of AWS spectrum from U.S. Cellular for $308 million in cash. The spectrum covers a total of 32 million people in 29 markets. The transaction further enhances our portfolio of nationwide broadband spectrum and enables the expansion of LTE coverage to new markets.

S-56

Distribution

We have approximately 70,000 total points of distribution, including approximately 7,500 branded locations, 10,000 third-party locations and 50,000 national retailer locations. Our distribution density in major metropolitan areas provides customers with the convenience of having retail and service locations close to where they live and work.

Customers

T-Mobile generates revenue from three primary categories of customers: branded postpaid, branded prepaid and wholesale. Branded postpaid customers generally include customers that are qualified to pay after incurring service and branded prepaid customers generally include customers who pay in advance. Our branded prepaid customers include customers of the T-Mobile, MetroPCS and GoSmart brands. Wholesale customers include Machine-to-Machine (“M2M”) customers and Mobile Virtual Network Operator (“MVNO”) customers that operate on the T-Mobile network, but are managed by wholesale partners. We generate the majority of our service revenues by providing wireless communication services to branded postpaid customers. Therefore, our ability to acquire and retain branded postpaid customers is significant to our business, including the generation of service revenues, equipment sales and other revenues.

During the three months ended September 30, 2013, 64% of our service revenues were generated by providing wireless communication services to branded postpaid customers, compared to 31% from branded prepaid customers, and 5% from wholesale customers, roaming and other services. During the nine months ended September 30, 2013, 71% of our service revenues were generated by providing wireless communication services to branded postpaid customers, compared to 24% from branded prepaid customers, and 5% from wholesale customers, roaming and other services.

Network modernization and migration

We are currently undergoing a $4 billion modernization program that includes site upgrades and spectrum re-farming. MetroPCS’ legacy subscribers will be migrated to the Company’s network, with the migration process expected to be completed in the second half of 2015. The T-Mobile network currently has the capacity to support the MetroPCS customer migration, and MetroPCS LTE customers will be able to use the T-Mobile network for data services without replacing their handsets. As MetroPCS’ existing subscribers are migrated to the combined company’s network, MetroPCS’ spectrum will be re-farmed to create capacity for increasing demand for HSPA+ and LTE services. It is anticipated that MetroPCS’ PCS spectrum will be migrated to HSPA+ and MetroPCS’ available AWS spectrum will be migrated to LTE. In addition, it is expected that T-Mobile’s AWS spectrum will be repurposed from HSPA+ to LTE over time. Through this process, we expect to emerge with one common LTE network with AWS as the primary LTE band.

Our spectrum position provides us with an average of approximately 74 MHz of spectrum in the top 100 major metropolitan areas and an average of approximately 77 MHz of spectrum in the top 25 major metropolitan areas. The complementary spectrum of T-Mobile and MetroPCS is expected to allow for greater 4G LTE bandwidth, including at least 20X20 MHz in many metropolitan areas, which is expected to yield high levels of efficiency and throughput. We expect to use our spectrum position to expand our high capacity 4G HSPA+ and LTE services, allowing us to offer customers better coverage, greater network reliability and faster speeds.

S-57

Competition

The wireless telecommunications industry is expected to remain highly competitive and we face substantial competition. We are the fourth largest facilities-based wireless telecommunications carrier in the United States based on the number of customers we serve. Our competitors include larger national carriers, such as AT&T, Verizon Wireless and Sprint, which offer predominantly contract-based service plans, smaller regional carriers, many of which offer no-contract, prepaid service plans, and many MVNOs, including TracFone. AT&T and Verizon Wireless are significantly larger than us and may enjoy greater resources and scale advantages as compared to us. Softbank, a large Japanese company, recently acquired 78% of the equity of Sprint and has announced plans to increase capital spending on network modernization and expansion. Other competitors may also compete effectively, including new entrants and companies using alternative business models.

Employees

As of September 30, 2013, we employed approximately 38,000 personnel.

Regulation

Pursuant to its authority under the Communications Act, the FCC regulates many key aspects of our business, including licensing, construction, the operation and use of our network, any modification of our network, control and ownership of our business, the sale of certain business assets, roaming arrangements and interconnection arrangements. The FCC has a number of complex requirements and proceedings that affect our operations and that could increase our costs or diminish our revenues. For example, the FCC has rules regarding provision of 911 and E911, porting telephone numbers, interconnection, roaming, internet openness, and the universal service and Lifeline programs. Many of these and other issues are being considered in ongoing proceedings, and we cannot predict whether or how such actions will affect our business, financial condition, or results of operations. Our ability to provide services and generate revenues could be harmed by adverse regulatory action or changes to existing laws and regulations. In addition, regulation of companies that offer competing services can impact our business indirectly.

Wireless communications providers must be licensed by the FCC to provide communications services at specified spectrum frequencies within specified geographic areas and must comply with the rules and policies governing the use of the spectrum as adopted by the FCC. The FCC issues each license for a fixed period of time, typically 10 years in the case of cellular, PCS services and point-to-point microwave licenses. AWS licenses have an initial term of 15 years, with successive 10-year terms thereafter. While the FCC has generally renewed licenses given to operating companies like us, the FCC has authority to both revoke a license for cause and to deny a license renewal if a renewal is not in the public interest. Furthermore, we could be subject to fines, forfeitures and other penalties (including, in extreme cases, revocation of our licenses) for failure to comply with FCC regulations, even if any such non-compliance was unintentional. The loss of any licenses, or any related fines or forfeitures, could adversely affect our business, results of operations and financial condition.

Additionally, Congress’ and the FCC’s allocation of additional spectrum for broadband commercial mobile radio service (“CMRS”), which includes cellular and personal communication services and specialized mobile radio, could significantly increase competition. We cannot assess the impact that any developments that may occur in the U.S. economy or any future spectrum

S-58

allocations by the FCC may have on license values. FCC spectrum auctions and other market developments may adversely affect the market value of our licenses in the future. A significant decline in the value of our licenses could adversely affect the carrying value of our licenses on our balance sheet and our results of operations and financial condition. In addition, the FCC periodically reviews its policies on how to evaluate a carrier’s spectrum holdings in the context of transactions and auctions. A change in these policies could affect spectrum resources and competition among us and other carriers.

Congress and the FCC have imposed limitations on foreign ownership of CMRS licensees that exceeds 20% direct ownership or 25% indirect ownership. The FCC has ruled that higher levels of indirect foreign ownership, even up to 100%, are presumptively consistent with the public interest. Consistent with that established policy, the FCC has issued a declaratory ruling authorizing up to 100% ownership of our company by Deutsche Telekom. This declaratory ruling—and our licenses—are conditioned on Deutsche Telekom’s compliance with a network security agreement with the Department of Justice, the Federal Bureau of Investigation and the Department of Homeland Security. Failure to comply with the terms of this agreement could result in fines, injunctions and other penalties, including potentially revocation of our spectrum licenses. The loss of any licenses, or any related fines or forfeitures, could adversely affect our business, results of operations and financial condition.

While the Communications Act generally preempts state and local governments from regulating the entry of, or the rates charged by, wireless carriers, certain state and local governments regulate other terms and conditions of wireless service, including billing, termination of service arrangements and the imposition of early termination fees, advertising, network outages, the use of handsets while driving, zoning and land use. Further, the FCC and the Federal Aviation Administration regulate the siting, lighting and construction of transmitter towers and antennae. Tower siting and construction are also subject to state and local zoning as well as federal statutes regarding environmental and historic preservation. The future costs to comply with all relevant regulations are to some extent unknown and regulations could result in higher operating expenses in the future.

Legal proceedings

We are involved in putative stockholder derivative and class action lawsuits challenging the business combination with MetroPCS. These lawsuits include:

• Paul Benn v. MetroPCS Communications, Inc. et al., Case No. C.A. 7938-CS filed on October 11, 2012 in the Delaware Court of Chancery;

• Joseph Marino v. MetroPCS Communications, Inc. et al., Case No. C.A. 7940-CS filed on October 11, 2012 in the Delaware Court of Chancery;

• Robert Picheny v. MetroPCS Communications, Inc. et al., Case No. C.A. 7971-CS filed on October 22, 2012 in the Delaware Court of Chancery;

• James McLearie v. MetroPCS Communications, Inc. et al., Case No. C.A. 8009-CS filed on November 5, 2012 in the Delaware Court of Chancery;

• Adam Golovoy et al. v. Deutsche Telekom et al., Cause No. CC-12-06144-A filed on October 10, 2012 in the Dallas, Texas County Court at Law; and

• Nagendra Polu et al. v. Deutsche Telekom et al., Cause No. CC-12-06170-E filed on October 10, 2012 in the Dallas, Texas County Court at Law.

S-59

The lawsuits allege that the various defendants breached fiduciary duties, or aided and abetted in the alleged breach of fiduciary duties, to the MetroPCS stockholders by entering into the transaction. The complaints allege claims for relief including, among other things, rescission to the extent the terms of the business combination have already been implemented, damages for the breaches of fiduciary duty, and the payment of plaintiffs’ attorneys’ fees and costs. In addition, on March 28, 2013, another lawsuit challenging the transaction and related disclosures, and alleging breaches of fiduciary duty to MetroPCS shareholders was filed in the U.S. District Court for the Southern District of New York entitled The Merger Fund et al. v. MetroPCS Communications, Inc. et al. This case was settled, and the complaint was dismissed with prejudice on September 30, 2013; and in the Delaware cases, plaintiffs have agreed to dismiss their claims and the parties have reached a settlement in principle. We intend to defend the remaining lawsuits vigorously and do not expect resolution of these matters to have a material adverse effect on our financial position, results of operations or cash flows.

We and our subsidiaries are involved in numerous lawsuits, regulatory proceedings, and other similar matters, including class actions and intellectual property claims, that arise in the ordinary course of business. Legal proceedings are inherently unpredictable, and often present complex legal and factual issues and can include claims for large amounts of damages. In our opinion at this time, these proceedings (individually and in the aggregate) should not have a material adverse effect on our financial position, results of operations or cash flows. These statements are based on our current understanding and assessment of relevant facts and circumstances. As such, our view of these matters is subject to inherent uncertainties and may change in the future.

We may, at our option, redeem some or all of (i) our 6.250% senior notes at any time on or after April 1, 2017 and (ii) our 6.625% senior notes at any time on or after April 1, 2018, in each case for the redemption prices set forth in the indenture governing our $3.5 billion senior notes. In addition, prior to April 1, 2016, we may also redeem up to 35% of the aggregate principal amount of our $3.5 billion senior notes with the net cash proceeds of certain sales of equity securities, including the sale of our common stock. The notes offered hereby will be issued under different indentures from those under which our $3.5 billion senior notes were issued, will not vote together with our $3.5 billion senior notes, will not be required to be redeemed on a pro rata basis with our $3.5 billion senior notes and will not trade with our $3.5 billion senior notes.

On September 21, 2010, MetroPCS consummated the sale of $1.0 billion principal amount of our 7 ⁷/₈% Senior Notes due 2018 (the “7 ⁷/₈ senior notes”), which were assumed by the Issuer in connection with the Business Combination Transaction. The 7 ⁷/₈% senior notes are unsecured obligations of the Issuer and are guaranteed by Parent and by all of the Issuer’s wholly-owned domestic restricted subsidiaries (other than certain designated special purpose entities and immaterial subsidiaries), all of the Issuer’s restricted subsidiaries that guarantee certain of the Issuer’s indebtedness and any future subsidiary of Parent that directly or indirectly owns any equity interests of the Issuer. Interest is payable on our 7 ⁷/₈% senior notes on March 1 and September 1 of each year. We may, at our option, redeem some or all of our 7 ⁷/₈% senior notes at any time on or after September 1, 2014 for the redemption prices set forth in the indenture governing our 7 ⁷/₈% senior notes. The notes offered hereby will be issued under different indentures from those under which our 7 ⁷/₈% senior notes were issued, will not vote together with our 7 ⁷/₈% senior notes, will not be required to be redeemed on a pro rata basis with our 7 ⁷/₈% senior notes and will not trade with our 7 ⁷/₈% senior notes.

On November 17, 2010, we consummated the sale of $1.0 billion principal amount of our 6 ⁵/₈% Senior Notes due 2020 (the “6 ⁵/₈% senior notes”), which were assumed by the Issuer in connection with the Business Combination Transaction. The 6 ⁵/₈% senior notes are unsecured obligations of the Issuer and are guaranteed by Parent and by all of the Issuer’s wholly-owned domestic restricted subsidiaries (other than certain designated special purpose entities and immaterial subsidiaries), all of the Issuer’s restricted subsidiaries that guarantee certain of the Issuer’s indebtedness and any future subsidiary of Parent that directly or indirectly owns any equity interests of the Issuer. Interest is payable on our 6 ⁵/₈% senior notes on May 15 and November 15 of each year. We may, at our option, redeem some or all of our 6 ⁵/₈% senior notes

S-72

at any time on or after November 15, 2015 for the redemption prices set forth in the indenture governing our 6 ⁵/₈% senior notes. In addition, prior to November 15, 2013, we may also redeem up to 35% of the aggregate principal amount of our 6 ⁵/₈% senior notes with the net cash proceeds of certain sales of equity securities, including the sale of our common stock. The notes offered hereby will be issued under different indentures from those under which our 6 ⁵/₈% senior notes were issued, will not vote together with our 6 ⁵/₈% senior notes, will not be required to be redeemed on a pro rata basis with our 6 ⁵/₈% senior notes and will not trade with our 6 ⁵/₈% senior notes.

The indentures governing the April 2013 senior notes, the 5.25% senior notes, the $3.5 billion senior notes, the 7 ⁷/₈% senior notes and the 6 ⁵/₈% senior notes (collectively, the “Existing Senior Notes”) contain customary events of default, covenants and other terms, including, among other things, covenants that restrict the ability of the Issuer and its subsidiaries to, inter alia, pay dividends and make certain other restricted payments, incur indebtedness and issue preferred stock, create liens on assets, sell or otherwise dispose of assets, enter into transactions with affiliates and enter new lines of business. These covenants include certain customary baskets, exceptions and incurrence-based ratio tests. The indentures governing the Existing Senior Notes do not contain any financial maintenance covenants. The covenants, events of default, and other non-economic terms of the notes offered hereby will be substantially identical to the covenants, events of default, and other non-economic terms of the Existing Senior Notes.

Working capital facility

On May 1, 2013, we entered into a Working Capital Facility (the “Working Capital Facility”) with Deutsche Telekom, as lender, and JPMorgan Chase Bank, N.A., as administrative agent, consisting of a $500.0 million revolving credit facility that terminates April 30, 2018. The Working Capital Facility is unsecured but is guaranteed by Parent, by all of the Issuer’s wholly-owned domestic restricted subsidiaries (other than certain designated special purpose entities, a certain reinsurance subsidiary and immaterial subsidiaries), by all of the Issuer’s subsidiaries that guarantee certain of the Issuer’s indebtedness, and by any future subsidiary of Parent that directly or indirectly owns any of the Issuer’s equity interests.

The Working Capital Facility will have an availability period of up to five years. Borrowings under the Working Capital Facility bear interest at a variable rate based on the London Interbank Offered Rate plus a spread of between 250 and 300 basis points, determined by reference to the Issuer’s debt-to-cash flow ratio. Also in connection with the Working Capital Facility, the Issuer pays Deutsche Telekom an unused commitment fee, payable quarterly, ranging from 25 to 50 basis points of any undrawn portion of the Working Capital Facility, to be determined by reference to the Issuer’s debt-to-cash flow ratio.

The Working Capital Facility contains events of default, representations, warranties, covenants and other terms that are customary. The Working Capital Facility also includes a financial covenant requiring that the Issuer’s debt-to-cash flow ratio shall not exceed a maximum level (the “WCF maximum debt-to-cash flow ratio”), which applies as a condition to borrowing (tested at the time of the borrowing giving pro forma effect to the borrowing) and at any time there are borrowings outstanding (tested on a quarterly basis). On November 15, 2013, we entered into an amendment to the Working Capital Facility that set the WCF maximum debt-to-cash flow ratio at 5.00 to 1.00 (for fiscal periods ending on or prior to December 31, 2013), 4.50 to 1.00 (for fiscal periods ending after December 31, 2013 and on or prior to December 31,2014) and 4.00 to 1.00 (for fiscal periods ending after December 31, 2014).

S-73

Tower transaction

Prior to the date of the Business Combination Agreement, the Issuer entered into an agreement with respect to the transfer of certain of its tower assets. On November 30, 2012, an initial closing was consummated pursuant to which nearly all of such tower assets were transferred, and the associated proceeds were received by the Issuer. On December 7, 2012, in accordance with the Business Combination Agreement, such proceeds (net of fees and expenses) were distributed to Deutsche Telekom.

Description of notes

You can find the definitions of certain terms used in this description of notes under the caption “—Certain Definitions” below. In this description of notes, “Issuer” refers only to T-Mobile USA, Inc., a Delaware corporation, and not to any of its Subsidiaries, and “Parent” refers only to T-Mobile US, Inc., a Delaware corporation, and not to any of its Subsidiaries.

Issuer will issue $2,000,000,000 in aggregate principal amount of notes in this offering as two series of debt: $                     in aggregate principal amount of notes will be notes due 2022 (the “2022 notes”) and $                     in aggregate principal amount of notes will be notes due 2024 (the “2024 notes”). Issuer will issue the notes under that certain base indenture (the “base indenture”) among itself, Parent, the Subsidiary Guarantors and Deutsche Bank Trust Company Americas, as trustee (the “trustee”) dated April 28, 2013, as supplemented with respect to each series of notes by a supplemental indenture (for each such series, the “supplemental indenture”) among Issuer, Parent, the Subsidiary Guarantors and the trustee. In this description of notes, the term “indenture” refers to the base indenture as supplemented separately by the supplemental indenture for each series of notes. The terms of the notes of each series include those stated in the indenture and those made part of the indenture by reference to the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”).

The obligations and covenants of Issuer described hereunder are only of Issuer and not of Parent, its direct parent company. Although Parent is a guarantor of the notes, it and its Subsidiaries, except Issuer and its Restricted Subsidiaries, are generally not subject to any of the obligations and covenants described hereunder.

The following description is a summary of the material provisions of the indenture. It does not restate the indenture in its entirety. We urge you to read the indenture in its entirety because it, and not this description of notes, defines your rights as a holder of the notes. For more information on how you can obtain a copy of the base indenture and supplemental indenture, see “Where You Can Find More Information.” Certain defined terms used in this description of notes but not defined below under “—Certain Definitions” have the meanings assigned to them in the indenture.

The registered holder of a note will be treated as the owner of the note for all purposes. Only registered holders will have rights under the indenture.

Brief description of the notes and the note guarantees

The notes

The notes of each series:

• will be general unsecured, unsubordinated obligations of Issuer;

• will be equal in right of payment with all existing and future Indebtedness and other liabilities of Issuer that are not by their terms subordinated in right of payment to the notes, including Issuer’s Existing Senior Notes;

• will be senior in right of payment to any future subordinated Indebtedness of Issuer to the extent that such future Indebtedness provides by its terms that it is subordinated to the notes; and

• will be unconditionally guaranteed on a senior unsecured basis by the Guarantors.

S-75

However, the notes will be effectively subordinated to all existing and future secured Indebtedness of Issuer or any Guarantor to the extent of the assets securing such Indebtedness and structurally subordinated to all liabilities and preferred stock of any of Issuer’s Subsidiaries that do not guarantee the notes to the extent of the assets of those Subsidiaries. See “Risk Factors—Risks Related to the Notes—The notes and the guarantees will be unsecured and effectively subordinated to Issuer’s and the guarantors’ existing and future secured indebtedness and structurally subordinated to any future indebtedness and other liabilities of Issuer’s non-guarantor subsidiaries.”

As of September 30, 2013, after giving effect to the issuance and sale of the notes offered hereby and the anticipated use of proceeds therefrom, we would have had approximately $22.6 billion of outstanding indebtedness, including $19.6 billion of outstanding indebtedness under our senior notes (including the notes offered hereby), approximately $0.4 billion of which would have been secured (and including approximately $2.49 billion of long term financial obligation relating to the Towers Transaction). The Issuer’s Subsidiaries that will not guarantee the notes had approximately $1.0 billion of total assets (excluding receivables due from Issuer and its guarantor Subsidiaries) and $2.3 billion in Indebtedness, other liabilities and preferred stock as of September 30, 2013.

The note guarantees

The notes will be guaranteed by Parent, all of Issuer’s Domestic Restricted Subsidiaries that are Wholly-Owned Subsidiaries (other than Designated Tower Entities, Immaterial Subsidiaries and the Reinsurance Entity), Issuer’s Restricted Subsidiaries that guarantee any Specified Issuer Indebtedness, and any future Subsidiary of Parent that directly or indirectly owns equity interests of Issuer. These Note Guarantees will be joint and several obligations of the Guarantors. The obligations of each Guarantor under its Note Guarantee will be limited as necessary to prevent that Note Guarantee from constituting a fraudulent conveyance under applicable law. See “Risk Factors—Risks Related to the notes—The guarantees may not be enforceable because of fraudulent conveyance laws.”

Each guarantee of the notes by a Guarantor:

• will be a general unsecured, unsubordinated obligation of that Guarantor;

• will be equal in right of payment with all existing and future Indebtedness and other liabilities of that Guarantor that are not by their terms subordinated to its guarantee of the notes, including its guarantee of Issuer’s Existing Senior Notes; and

• will be senior in right of payment to any future subordinated Indebtedness of that Guarantor to the extent that such future Indebtedness provides by its terms that it is subordinated in right of payment to its guarantee of the notes.

However, the guarantees will be effectively subordinated to all existing and future secured Indebtedness of the Guarantors to the extent of the assets securing such Indebtedness and structurally subordinated to all liabilities and preferred stock of any Subsidiaries of such guarantors that do not guarantee the notes to the extent of the assets of those Subsidiaries. See “Risk Factors—Risks Related to the Notes—The notes and the guarantees will be unsecured and effectively subordinated to Issuer’s and the guarantors’ existing and future secured indebtedness and structurally subordinated to any future indebtedness and other liabilities of Issuer’s non-guarantor subsidiaries.”

S-76

Under the circumstances described below under the subheading “—Certain Covenants—Additional Note Guarantees,” one or more of Issuer’s Subsidiaries (including Issuer’s existing Domestic Restricted Subsidiaries) together with certain newly created or acquired Subsidiaries in the future may not guarantee the notes. In the event of a bankruptcy, liquidation or reorganization of any of these non-guarantor Subsidiaries, the non-guarantor Subsidiaries will pay their trade creditors and holders of their debt and other obligations before they will be able to distribute any of their assets to Issuer.

As of the Series Issue Date, all of Issuer’s Subsidiaries will be “Restricted Subsidiaries.” However, under the circumstances described below under the caption “—Certain Covenants—Designation of Restricted and Unrestricted Subsidiaries,” Issuer will be permitted to designate certain of its Subsidiaries as “Unrestricted Subsidiaries.” Issuer’s Unrestricted Subsidiaries will not be subject to many of the restrictive covenants in the indenture. Issuer’s Unrestricted Subsidiaries will not guarantee the notes.

Except as otherwise provided in the following paragraph, a Guarantor of the notes of any series (other than Parent) may not sell or otherwise dispose of all or substantially all of its assets to, or consolidate with or merge with or into (whether or not such Guarantor is the surviving Person) another Person, other than Issuer or another Guarantor, unless:

(1) immediately after giving effect to that transaction, no Default or Event of Default exists; and

(2) either:

(a) subject to the following paragraph and if it is not already a Guarantor of the notes of such series, the Person acquiring the property in any such sale or disposition or the Person formed by or surviving any such consolidation or merger assumes all the obligations of that Guarantor under the indenture and its Note Guarantee of the notes of such series pursuant to a supplemental indenture; or

(b) such sale or other disposition complies with the “Asset Sale” provisions of the indenture (it being understood that only such portion of the Net Proceeds as is or is required to be applied on or before the date of such release in accordance with the terms of the indenture needs to be so applied).

The Note Guarantee of a Guarantor will be released in respect of the notes of any series:

(1) only in the case of a Subsidiary Guarantor, in connection with any sale or other disposition of all or substantially all of the assets of that Subsidiary Guarantor (including by way of merger or consolidation) to a Person that is not (either before or after giving effect to such transaction) Issuer or a Restricted Subsidiary of Issuer, if the sale or other disposition is not prohibited by the “Asset Sale” provisions of the indenture;

(2) only in the case of a Subsidiary Guarantor, in connection with any issuance, sale or other disposition of Capital Stock of that Subsidiary Guarantor to a Person that is not (either before or after giving effect to such transaction) Issuer or a Restricted Subsidiary of Issuer, if the issuance, sale or other disposition does not violate the “Asset Sale” or “Restricted Investment” provisions of the indenture, and the Subsidiary Guarantor ceases to be a Wholly-Owned Subsidiary of Issuer as a result of such sale or other disposition and does not guarantee any Specified Issuer Indebtedness;

S-77

(3) if such Guarantor (other than Parent) ceases to guarantee any Specified Issuer Indebtedness and such Guarantor would not otherwise be required to guarantee the series of notes pursuant to the covenant described below under the caption “—Additional Note Guarantees”;

(4) if Issuer designates any Restricted Subsidiary that is a Guarantor to be an Unrestricted Subsidiary in accordance with the applicable provisions of the indenture;

(5) upon the legal defeasance, covenant defeasance, or satisfaction and discharge of the indenture as provided below under the captions “—Legal Defeasance and Covenant Defeasance” and “—Satisfaction and Discharge”;

(6) upon the liquidation or dissolution of such Guarantor (other than Parent) provided no Default or Event of Default has occurred that is continuing; or

(7) if such Guarantor becomes an Immaterial Subsidiary and such Guarantor would not otherwise be required to guarantee the series of notes pursuant to the covenant described below under the caption “—Additional Note Guarantees.”

See “—Repurchase at the Option of Holders—Asset Sales” below.

Principal, maturity and interest

Issuer has outstanding $17.2 billion in aggregate principal amount of senior notes. Issuer will issue $2,000,000,000 in aggregate principal amount of notes in this offering, of which $                     in aggregate principal amount will be 2022 notes and $                     in aggregate principal amount will be 2024 notes. Issuer may issue additional notes of either series from time to time, and such additional notes of such series may be issued under the base indenture as supplemented either by the supplemental indenture for such series of notes or one or more other supplemental indentures. Any issuance of additional notes is subject to all of the covenants in the indenture, including the covenant described below under the caption “—Certain Covenants—Incurrence of Indebtedness and Issuance of Preferred Stock.” The notes of either series and any additional notes of such series subsequently issued will be treated as a single series for all purposes under the indenture, including, without limitation, waivers, amendments, redemptions and offers to purchase. Issuer will issue notes in minimum denominations of $2,000 and integral multiples of $1,000. The 2022 notes will mature on January 15, 2022 and the 2024 notes will mature on January 15, 2024.

Interest on the 2022 notes will accrue at the rate of     % per annum, and interest on the 2024 notes will accrue at the rate of     % per annum, and interest on each series of notes will be payable semiannually in arrears on January 15 and July 15, commencing on July 15, 2014. Issuer will make each interest payment to the holders of record on the immediately preceding January 1 and July 1.

Interest on the notes will accrue from the date of original issuance or, if interest has already been paid, from the date it was most recently paid. Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months. If an interest payment date or the maturity date falls on a day that is not a business day, the related payment of principal or interest will be made on the next succeeding business day as if made on the date the payment was due, and no interest shall accrue for the intervening period.

S-78

Payments of principal of and interest on the notes issued in book-entry form or definitive form, if any, will be made as described below under the caption “—Methods of Receiving Payments on the Notes.”

Each series of notes initially will be evidenced by one or more global notes deposited with a custodian for, and registered in the name of, Cede & Co., as nominee of The Depository Trust Company (“DTC”). Except as described below, beneficial interests in the global notes will be shown on, and transfers thereof will be effected only through, records maintained by DTC and its direct and indirect participants. We do not intend to apply for the notes to be listed on any securities exchange or to arrange for the notes to be quoted on any quotation system.

Methods of receiving payments on the notes

If a holder of a definitive note has given wire transfer instructions to Issuer and Issuer is the paying agent, Issuer will pay all principal, interest and premium, if any, on that holder’s notes in accordance with those instructions until given written notice to the contrary. All other payments on the notes will be made at the Corporate Trust Office of the Trustee, unless Issuer elects to make interest payments by check mailed to the noteholders at their address set forth in the books and records of the registrar.

Paying agent and registrar for the notes

The trustee will initially act as paying agent and registrar. Issuer may change the paying agent or registrar without prior notice to the holders of the notes, and Issuer or any of its Subsidiaries may act as paying agent or registrar.

Transfer and exchange

Except as set forth below, the global notes may be transferred, in whole and not in part, only to another nominee of DTC or to a successor of DTC or its nominee, as described below under the caption “—Book-entry, Delivery and Form.”

A holder of a definitive note may transfer or exchange notes in accordance with the provisions of the indenture. The registrar and the trustee may require a holder, among other things, to furnish appropriate endorsements and transfer documents in connection with a transfer of notes. Holders will be required to pay all taxes relating to, arising out of, or in connection with such transfer. Issuer will not be required to transfer or exchange any note selected for redemption. Also, Issuer will not be required to transfer or exchange any note for a period of 15 days before a selection of notes to be redeemed.

S-79

Mandatory redemption

Issuer is not required to make mandatory redemption or sinking fund payments with respect to the notes.

Repurchase at the option of holders

Change of control triggering event

If a Change of Control Triggering Event occurs with respect to either series of notes, each holder of notes of such series will have the right to require Issuer to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000) of that holder’s notes of such series pursuant to a

S-81

Change of Control Offer on the terms set forth in the indenture. In the Change of Control Offer, Issuer will offer a Change of Control Payment in cash equal to 101% of the aggregate principal amount of notes repurchased plus accrued and unpaid interest on the notes repurchased to, but not including, the date of purchase, subject to the rights of holders of notes on the relevant record date to receive interest due on the relevant interest payment date for periods prior to such repurchase date (the “Change of Control Payment”). Within 30 days following any Change of Control Triggering Event, Issuer will send a notice (the “Change of Control Offer”) to each holder of notes to which such Change of Control Triggering Event applies and the trustee describing the transaction or transactions and identify the ratings decline that together constitute the Change of Control Triggering Event and offering to repurchase the notes of such series on the Change of Control Payment Date specified in the notice, which date will be no earlier than 10 days and no later than 60 days from the date such notice is sent (the “Change of Control Payment Date”), pursuant to the procedures required by the indenture and described in such notice. Issuer will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the notes as a result of a Change of Control Triggering Event. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control Triggering Event provisions of the indenture, or compliance with the Change of Control Triggering Event provisions of the indenture would constitute a violation of any such laws or regulations, Issuer will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Change of Control Triggering Event provisions of the indenture by virtue of such compliance. In connection with the tender of any notes with respect to a Change of Control Triggering Event, the tendering holder shall provide good title to the notes, free and clear of all liens and encumbrances, and shall represent and warrant that such holder is presenting good title, free and clear of all liens and encumbrances, and such other representations and warranties as are customary.

On the Change of Control Payment Date, Issuer will, to the extent lawful:

(1) accept for payment all notes or portions of notes properly tendered pursuant to the Change of Control Offer;

(2) deposit with the paying agent an amount equal to the Change of Control Payment in respect of all notes or portions of notes properly tendered; and

(3) deliver or cause to be delivered to the paying agent the notes properly accepted together with an officers’ certificate stating the aggregate principal amount of notes or portions of notes being purchased by Issuer.

The paying agent will promptly make payment, to each holder of notes properly tendered, of the Change of Control Payment for such notes, and the trustee will promptly authenticate and mail (or cause to be transferred by book entry) to each holder, a new note equal in principal amount to any unpurchased portion of the notes surrendered, if any; provided that each new note will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof. Issuer will publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date.

The provisions described above that require Issuer to make a Change of Control Offer following a Change of Control Triggering Event will be applicable whether or not any other provisions of the indenture are applicable. Except as described above with respect to a Change of Control

S-82

Triggering Event, the indenture does not contain provisions that permit the holders of the notes to require, or otherwise provide, that Issuer repurchase or redeem the notes in the event of a takeover, recapitalization or similar transaction.

Notwithstanding the foregoing, Issuer will not be required to make a Change of Control Offer with respect to either series of notes upon a Change of Control Triggering Event if (1) a third party makes the Change of Control Offer for such series of notes in the manner, at the times and otherwise in compliance with the requirements set forth in the indenture applicable to a Change of Control Offer made by Issuer and purchases all notes of such series properly tendered and not withdrawn under the Change of Control Offer, or (2) notice of redemption with respect to such series has been given pursuant to the indenture as described above under the caption “—Optional Redemption,” unless and until there is a default in payment of the applicable redemption price.

A Change of Control Offer may be made in advance of a Change of Control Triggering Event, and conditioned upon such Change of Control Triggering Event, if a definitive agreement has been executed for a transaction that would constitute a Change of Control at the time of making of the Change of Control Offer.

In the event that holders of not less than 90% of the aggregate principal amount of the outstanding notes of either series accept a Change of Control Offer and Issuer purchases all of the notes of such series held by such holders, Issuer will have the right, upon not less than 10 nor more than 60 days’ notice (in the case of redemptions upon less than 30 days’ notice, subject to the ability of DTC to process such redemption on the date specified in such notice), given not more than 30 days following the purchase pursuant to the Change of Control Offer described above, to redeem all of the notes of such series that remain outstanding following such purchase at a redemption price equal to the Change of Control Payment plus, to the extent not included in the Change of Control Payment, accrued and unpaid interest on the notes of such series that remain outstanding, to, but not including, the date of redemption (subject to the right of holders of record on the relevant record date to receive interest due on an interest payment date that is on or prior to the redemption date).

The definition of Change of Control includes a phrase relating to the direct or indirect sale, lease, transfer, conveyance or other disposition of “all or substantially all” of the properties or assets of Issuer and its Restricted Subsidiaries taken as a whole. Although there is a limited body of case law interpreting the phrase “substantially all,” there is no precise established definition of the phrase under applicable law. Accordingly, the ability of a holder of notes to require Issuer to repurchase its notes as a result of a sale, lease, transfer, conveyance or other disposition of less than all of the assets of Issuer and its Restricted Subsidiaries taken as a whole to another Person or group may be uncertain.

Asset sales

Issuer will not, and will not permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless:

(1) Issuer (or the Restricted Subsidiary, as the case may be) receives consideration at the time of the Asset Sale at least equal to the Fair Market Value of the assets or Equity Interests issued or sold or otherwise disposed of; and

S-83

(2) at least 75% of the consideration received by Issuer or such Restricted Subsidiary in the Asset Sale and all other Asset Sales since the Closing Date is in the form of cash, Cash Equivalents or Replacement Assets or a combination thereof. For purposes of this provision, each of the following will be deemed to be cash:

(a) any liabilities, as shown on Issuer’s most recent consolidated balance sheet (or as would be shown on Issuer’s consolidated balance sheet as of the date of such Asset Sale), of Issuer or any Restricted Subsidiary (other than contingent liabilities and liabilities that are by their terms subordinated to the notes or any Note Guarantees) that are assumed by the transferee of any such assets pursuant to a novation agreement that releases Issuer or such Restricted Subsidiary from further liability; and

(b) any securities, notes or other obligations received by Issuer, or any such Restricted Subsidiary, from such transferee that are converted by Issuer or such Restricted Subsidiary into cash, Cash Equivalents or Replacement Assets within 90 days after such Asset Sale, to the extent of the cash, Cash Equivalents or Replacement Assets received in that conversion.

Notwithstanding the foregoing, the 75% limitation referred to above shall be deemed satisfied with respect to any Asset Sale in which the cash, Cash Equivalents or Replacement Assets portion of the consideration received therefrom, determined in accordance with the foregoing provision on an after-tax basis, is equal to or greater than what the after-tax proceeds would have been had such Asset Sale complied with the aforementioned 75% limitation.

Within 365 days after the receipt of any Net Proceeds from an Asset Sale, Issuer or a Restricted Subsidiary may apply an amount equal to such Net Proceeds:

(1) to purchase Replacement Assets; or

(2) to prepay, repay, defease, redeem, purchase or otherwise retire Indebtedness and other Obligations under a Credit Facility or Indebtedness secured by property that is subject to such Asset Sale and, if the Indebtedness repaid is revolving credit Indebtedness, to correspondingly reduce commitments with respect thereto.

Notwithstanding the foregoing, if within 365 days after the receipt of any Net Proceeds from an Asset Sale, Issuer or a Restricted Subsidiary enters into a binding written agreement committing Issuer or such Restricted Subsidiary, subject to customary conditions, to an application of funds of the kind described in clause (1) above, Issuer or such Restricted Subsidiary shall be deemed not to be in violation of the preceding paragraph so long as such application of funds is consummated within 545 days of the receipt of such Net Proceeds.

Pending the final application of any Net Proceeds of an Asset Sale, Issuer may temporarily reduce revolving credit borrowings or otherwise use the Net Proceeds in any manner that is not prohibited by the indenture.

An amount equal to any Net Proceeds from Asset Sales that are not applied or invested as provided in the third paragraph of this covenant will constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds exceeds $100.0 million, within 20 days thereof, Issuer shall apply the entire aggregate amount of unutilized Excess Proceeds (not only the amount in excess of $100.0 million) to make an offer (an “Asset Sale Offer”) to all holders of notes and all holders of other Indebtedness that is pari passu with the notes containing provisions requiring Issuer to make an offer to purchase or redeem with the proceeds of sales of assets to purchase the

S-84

maximum principal amount of notes and purchase or redeem such other pari passu Indebtedness that may be purchased or redeemed out of the Excess Proceeds. The offer price in any Asset Sale Offer will be equal to 100% of the principal amount of the notes and such other pari passu Indebtedness that may be purchased or redeemed with Excess Proceeds, plus accrued and unpaid interest to, but not including, the date of consummation of the purchase, and will be payable in cash. If any Excess Proceeds remain after consummation of an Asset Sale Offer, Issuer and its Restricted Subsidiaries may use those Excess Proceeds for any purpose not otherwise prohibited by the indenture. If the aggregate principal amount of notes and other pari passu Indebtedness tendered in response to such Asset Sale Offer exceeds the amount of Excess Proceeds, the trustee shall select the notes and Issuer will select such other pari passu Indebtedness to be purchased or redeemed on a pro rata basis unless otherwise required by law or applicable stock exchange or depositary requirements. Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero.

Issuer will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with each repurchase of notes pursuant to an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with the Asset Sale provisions of the indenture, or compliance with the Asset Sale provisions of the indenture would constitute a violation of any such laws or regulations, Issuer will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Asset Sale provisions of the indenture by virtue of such compliance.

The agreements governing Issuer’s other Indebtedness contain, and future agreements may contain, prohibitions of certain events, including events that would constitute a Change of Control or an Asset Sale and may prohibit repurchases of or other prepayments in respect of the notes. The exercise by the holders of the notes of their right to require Issuer to repurchase the notes upon a Change of Control Triggering Event or an Asset Sale could cause a default under these other agreements, even if the Change of Control Triggering Event or Asset Sale itself does not, due to the financial effect of such repurchases or other prepayments on Issuer. In the event a Change of Control Triggering Event or Asset Sale occurs at a time when Issuer is prohibited from purchasing notes, Issuer could seek the consent of the holders of such Indebtedness to the purchase of notes or could attempt to refinance the borrowings that contain such prohibition. If Issuer does not obtain a consent or repay those borrowings, Issuer will remain prohibited from purchasing notes. In that case, Issuer’s failure to purchase tendered notes would constitute an Event of Default under the applicable indenture that could, in turn, constitute a default under the other Indebtedness. Finally, Issuer’s ability to pay cash to the holders of notes upon a repurchase may be limited by Issuer’s then existing financial resources. See “Risk Factors—Risks Related to the Notes—The indenture governing the notes, the indentures governing our Existing Senior Notes and our Working Capital Facility include restrictive covenants that limit our operating flexibility.”

Selection and notice

If less than all of the notes of a series are to be redeemed, the trustee will select notes of such series for redemption on a pro rata basis unless otherwise required by law or applicable stock exchange or depositary requirements.

No notes of $2,000 or less can be redeemed in part. Notices of redemption will be sent electronically or mailed by first class mail at least 10 but not more than 60 days before the

S-85

redemption date to each holder of notes to be redeemed at its registered address, except that redemption notices may be sent more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the notes of a series or a satisfaction and discharge of the indenture with respect to such series. Except as otherwise set forth in the provisions described under the caption “—Repurchase at the Option of Holders—Change of Control Triggering Event,” notices of redemption may not be conditional.

If any note is to be redeemed in part only, the notice of redemption that relates to that note will state the portion of the principal amount of that note that is to be redeemed. If in definitive form a new note in principal amount equal to the unredeemed portion of the original note will be issued in the name of the holder of notes upon cancellation of the original note. Except to the extent that a notice of redemption is conditional as permitted in the provisions described under the caption “—Repurchase at the Option of Holders—Change of Control Triggering Event,” notes called for redemption become due on the date fixed for redemption. On and after the redemption date, interest ceases to accrue on notes or portions of notes called for redemption.

Certain covenants

Changes in covenants when notes rated investment grade

If on any date following the Series Issue Date with respect to a series of notes:

(1) the notes of such series are rated Investment Grade by two out of the three Rating Agencies; and

(2) no Default or Event of Default shall have occurred and be continuing with respect to the notes of such series (other than with respect to the covenants specifically listed under the following captions),

then, beginning on that day, the covenants specifically listed under the following captions in this prospectus supplement will cease to apply to such series of notes and will not be later reinstated even if the ratings of the notes of such series should subsequently decline:

(1) “—Repurchase at the Option of Holders—Asset Sales”;

(2) “—Restricted Payments”;

(3) “—Incurrence of Indebtedness and Issuance of Preferred Stock”;

(4) “—Dividend and Other Payment Restrictions Affecting Subsidiaries”;

(5) “—Transactions with Affiliates”;

(6) “—Designation of Restricted and Unrestricted Subsidiaries”; and

(7) clauses (3) (to the extent that a Default or Event of Default exists by reason of one or more of the covenants specifically listed in this paragraph) and (4) of the covenant described below under the caption “—Merger, Consolidation or Sale of Assets.”

There can be no assurance that the notes of either series will ever achieve an Investment Grade rating.

S-86

Restricted payments

Issuer will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly:

(1) declare or pay (without duplication) any dividend, or make any other payment or distribution, on account of Issuer’s or any of its Restricted Subsidiaries’ Equity Interests (including any payment in connection with any merger or consolidation involving Issuer or any of its Restricted Subsidiaries) or to the direct or indirect holders of Issuer’s or any of its Restricted Subsidiaries’ Equity Interests in their capacity as such (other than dividends or distributions payable in Equity Interests (other than Disqualified Stock) of Issuer and other than dividends or distributions payable to Issuer or a Restricted Subsidiary of Issuer);

(2) purchase, redeem or otherwise acquire or retire for value (including in connection with any merger or consolidation involving Issuer) any Equity Interests of Issuer or any direct or indirect parent of Issuer;

(3) make any payment on or with respect to, or purchase, redeem, defease or otherwise acquire or retire for value any Subordinated Indebtedness (excluding any intercompany Indebtedness between or among Issuer and any of its Restricted Subsidiaries), except a payment of interest or principal at the Stated Maturity thereof; or

(4) make any Restricted Investment (all such payments and other actions set forth in clauses (1) through (4) above being collectively referred to as “Restricted Payments”),

unless, at the time of and after giving effect to such Restricted Payment:

(1) no Default or Event of Default has occurred and is continuing or would occur as a consequence of such Restricted Payment;

(2) Issuer would, at the time of such Restricted Payment and after giving pro forma effect thereto as if such Restricted Payment had been made at the beginning of the applicable four-quarter period, have been permitted to incur at least $1.00 of additional Indebtedness pursuant to the Debt to Cash Flow Ratio test set forth in the first paragraph of the covenant described below under the caption “—Incurrence of Indebtedness and Issuance of Preferred Stock”; and

(3) such Restricted Payment, together with the aggregate amount of all other Restricted Payments made by Issuer and its Restricted Subsidiaries since the Closing Date (excluding Restricted Payments permitted by clauses (2), (3), (4), (5), (6), (7), (8), (9), (11), (12), (13), (14) and (15) of the next succeeding paragraph), is less than the sum, without duplication, of:

(a) 100% of Issuer’s Consolidated Cash Flow for the period (taken as one accounting period) from and after the Closing Date to the end of Issuer’s most recently ended fiscal quarter for which internal financial statements are available at the time of such Restricted Payment, less the product of 1.4 times Issuer’s Consolidated Interest Expense for the same period; plus

(b) 100% of the aggregate net cash proceeds, and the Fair Market Value of any property other than cash, in each case received by Issuer after the Closing Date as a contribution to its common equity capital (other than any such contribution resulting, or deemed to result, from the Merger) or from the issue or sale of Equity Interests of Issuer (other than Disqualified Stock) or from the issue or sale of convertible or exchangeable Disqualified

S-87

Stock or convertible or exchangeable debt securities of Issuer that have been converted into or exchanged for such Equity Interests (other than Equity Interests (or Disqualified Stock or debt securities) sold to a Subsidiary of Issuer); plus

(c) to the extent that any Restricted Investment that was made after the Closing Date, or, that any Restricted Investment that was made by MetroPCS Wireless, Inc. or any of its Restricted Subsidiaries after November 3, 2006 and prior to the Closing Date (provided that, and solely to the extent that, such Restricted Investment, at the time made, reduced the amount that would be calculated pursuant to clause (g) below), in each case, is sold for cash or Cash Equivalents, or otherwise is liquidated or repaid for cash or Cash Equivalents, an amount equal to such cash and Cash Equivalents; plus

(d) to the extent that any Unrestricted Subsidiary of Issuer designated as such after the Closing Date is redesignated as a Restricted Subsidiary after the Closing Date, the Fair Market Value of Issuer’s Investment in such Subsidiary as of the date of such redesignation; other than to the extent such Investment constituted a Permitted Investment; plus

(e) 100% of any cash dividends or cash distributions, and the Fair Market Value of any property other than cash, in each case actually received directly or indirectly by Issuer or a Restricted Subsidiary of Issuer that is a Guarantor after the Closing Date from an Unrestricted Subsidiary of Issuer, in each case, to the extent that such dividends, cash distributions or other property were not otherwise included in the Consolidated Net Income of Issuer for such period and other than to the extent such Investment constituted a Permitted Investment; minus

(f) the aggregate amount of any Net Equity Proceeds taken into account for purposes of incurring Indebtedness pursuant to clause (14) of the definition of “Permitted Debt” set forth below under the caption “—Incurrence of Indebtedness and Issuance of Preferred Stock,” after the Closing Date; plus

(g) the amount that would be calculated immediately prior to the consummation of the Merger on the Closing Date pursuant to clause (3) of the second paragraph of Section 4.07(a) of the 6 ⁵/₈% Senior Notes Indenture, as in effect immediately prior to the effectiveness of the 6 ⁵/₈% Senior Notes Sixth Supplemental Indenture (provided that any calculation of cumulative Consolidated Cash Flow and Consolidated Interest Expense in subclause (A) of such clause (3) shall include (x) Issuer’s last fiscal quarter ending prior to the Closing Date, and (y) the period from the beginning of Issuer’s fiscal quarter during which the Closing Date occurs to the Closing Date, in each case, if internal financial statements are available for such period at the time of calculation, even if they are not available immediately prior to the consummation of the Merger on the Closing Date).

As of September 30, 2013, the amount calculated pursuant to clause (3)(a)—(g) above (the “RP Basket”), was approximately $5.7 billion. If the Common Stock Offering, including sales pursuant to the Underwriters’ Option, is consummated and the net proceed thereof are contributed to the Issuer as a contribution to its equity capital, the RP Basket would increase by the amount of such net proceeds (subject, however, to clause (f) above).

S-88

So long as no Default has occurred and is continuing or would be caused thereby, the preceding provisions will not prohibit:

(1) the payment of any dividend or the consummation of any irrevocable redemption within 60 days after the date of declaration of the dividend or giving of the redemption notice, as the case may be, if at the date of declaration or notice, the dividend or redemption payment would have complied with the provisions of the indenture;

(2) the making of any Restricted Payment in exchange for, or out of the net cash proceeds of the substantially concurrent sale (other than to a Subsidiary of Issuer) of, Equity Interests of Issuer (other than Disqualified Stock) or from the substantially concurrent contribution of common equity capital to Issuer; provided that the amount of any such net cash proceeds that are utilized for any such Restricted Payment will be excluded from clause (3)(b) of the preceding paragraph; provided, further, that any Net Equity Proceeds (x) used for making a Restricted Investment pursuant to clause (10) of this paragraph or (y) taken into account for purposes of incurring Indebtedness pursuant to clause (14) of the definition of “Permitted Debt” set forth below under the caption “—Incurrence of Indebtedness and Issuance of Preferred Stock,” may not also be used to make a Restricted Payment pursuant to this clause (2);

(3) the repurchase, redemption, defeasance or other acquisition or retirement for value of Subordinated Indebtedness of Issuer or any Subsidiary Guarantor with the net cash proceeds from a substantially concurrent incurrence of Permitted Refinancing Indebtedness;

(4) the payment of any dividend (or, in the case of any partnership or limited liability company, any similar distribution) by a Restricted Subsidiary of Issuer to the holders of its Equity Interests on a pro rata basis;

(5) the repurchase, redemption or other acquisition or retirement for value of any Equity Interests of Parent, Issuer, any Restricted Subsidiary of Issuer or any direct or indirect parent of Issuer held by any current or former officer, director, employee or consultant of Parent, Issuer or any of its Restricted Subsidiaries pursuant to any equity subscription agreement, stock option agreement, shareholders’ agreement or similar agreement; provided that the aggregate price paid for all such repurchased, redeemed, acquired or retired Equity Interests may not exceed an amount equal to $50.0 million in any fiscal year; provided, further, that such amount in any fiscal year may be increased by an amount equal to (a) the net cash proceeds contributed to Issuer from the sale of Equity Interests of Parent to current or former members of management, directors, consultants or employees that occurs after the Closing Date plus (b) the net cash proceeds of key man life insurance policies received by Parent or its Restricted Subsidiaries after the Closing Date; provided, further, that such amount in any fiscal year shall be reduced by the amount of Indebtedness incurred in such fiscal year pursuant to clause (21) of the second paragraph of the covenant described below under the caption “—Incurrence of Indebtedness and Issuance of Preferred Stock”;

(6) the repurchase, redemption or other acquisition or retirement of Equity Interests deemed to occur upon the exercise or exchange of stock options, warrants or other similar rights to the extent such Equity Interests represent a portion of the exercise or exchange price of those stock options, warrants or other similar rights, and the repurchase, redemption or other acquisition or retirement of Equity Interests made in lieu of withholding taxes resulting from the vesting, exercise or exchange of stock options, warrants or other similar rights;

S-89

(7) the declaration and payment of regularly scheduled or accrued dividends to holders of any class or series of Disqualified Stock of Issuer or any Restricted Subsidiary of Issuer issued on or after the Closing Date in accordance with the Debt to Cash Flow Ratio test described below under the caption “—Incurrence of Indebtedness and Issuance of Preferred Stock”;

(8) Permitted Payments to Parent;

(9) the repurchase, redemption or other acquisition or retirement for value of any Equity Interests of Parent to the extent necessary to comply with law or to prevent the loss or secure the renewal or reinstatement of any FCC License held by Issuer or any of its Subsidiaries;

(10) Restricted Investments in an amount equal to 100% of the aggregate amount of any Net Equity Proceeds, less the aggregate amount of any Net Equity Proceeds (x) used for making a Restricted Payment pursuant to clause (2) of this paragraph or (y) taken into account for purposes of incurring Indebtedness pursuant to clause (14) of the definition of “Permitted Debt” set forth below under the caption “—Incurrence of Indebtedness and Issuance of Preferred Stock”;

(11) payments made to DT or its Subsidiaries from the proceeds of the Towers Transaction;

(12) the repurchase, redemption or other acquisition or retirement for value of any Subordinated Indebtedness pursuant to the provisions similar to those described under the captions “—Repurchase at the Option of Holders—Change of Control Triggering Event” and “—Repurchase at the Option of Holders—Asset Sales”; provided that all notes tendered by the holders of the notes in connection with a Change of Control Offer or Asset Sale Offer, as applicable, have been repurchased, redeemed or otherwise acquired for value;

(13) Restricted Payments in connection with the Cash Payment, as defined in the Business Combination Agreement;

(14) the making of cash payments in connection with any conversion of Convertible Debt in an aggregate amount since the Closing Date not to exceed the sum of (a) the principal amount of such Convertible Debt plus (b) any payments received by Issuer or any of its Restricted Subsidiaries pursuant to the exercise, settlement or termination of any related Permitted Bond Hedge Transactions; and

(15) other Restricted Payments in an aggregate amount since the Closing Date not to exceed $375.0 million.

The amount of all Restricted Payments (other than cash) will be the Fair Market Value on the date of the Restricted Payment of the asset(s) or securities proposed to be transferred or issued by Issuer or such Restricted Subsidiary, as the case may be, pursuant to the Restricted Payment.

Incurrence of indebtedness and issuance of preferred stock

Issuer will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee or otherwise become directly or indirectly liable, contingently or otherwise, with respect to (collectively, “incur”) any Indebtedness (including Acquired Debt), and Issuer will not issue any Disqualified Stock and will not permit any of its Restricted Subsidiaries to issue any shares of Preferred Stock; provided, however, that Issuer may incur Indebtedness (including Acquired Debt) or issue Disqualified Stock and the Subsidiary

S-90

Guarantors may incur Indebtedness (including Acquired Debt) or issue Preferred Stock, if the Debt to Cash Flow Ratio for Issuer’s most recently ended four full fiscal quarters for which internal financial statements are available immediately preceding the date on which such additional Indebtedness is incurred or such Disqualified Stock or such Preferred Stock is issued, as the case may be, would have been no greater than 6.0 to 1, determined on a pro forma basis (including a pro forma application of the net proceeds therefrom), as if the additional Indebtedness had been incurred or the Disqualified Stock or the Preferred Stock had been issued, as the case may be, at the beginning of such four-quarter period.

The first paragraph of this covenant will not prohibit the incurrence of any of the following items of Indebtedness (collectively, “Permitted Debt”), nor will it prohibit Issuer’s Restricted Subsidiaries from issuing the following types of Preferred Stock:

(1) the incurrence by Issuer and any Subsidiary Guarantor of (a) additional Indebtedness under Credit Facilities, provided that giving effect to such incurrence, the aggregate principal amount (with letters of credit being deemed to have a principal amount equal to the maximum potential liability of Issuer and its Restricted Subsidiaries thereunder) of all Indebtedness under Credit Facilities then outstanding under this paragraph (1), together with any Indebtedness incurred pursuant to the following clause (b), does not exceed the greater of (x) $9.0 billion and (y) 150% of the Consolidated Cash Flow of Issuer and its Subsidiaries for the most recently ended four full fiscal quarters for which financial statements are available, calculated on a pro forma basis in the manner described in the definition of “Debt to Cash Flow Ratio” and (b) without duplication, all Indebtedness incurred to renew, refund, refinance, replace, defease or discharge any Indebtedness incurred pursuant to the foregoing clause (a); provided, however, that the maximum amount permitted under this clause (1) shall not be deemed to limit additional Indebtedness under the Credit Facilities to the extent that the incurrence of such additional Indebtedness is permitted pursuant to any of the other provisions of this covenant;

(2) the incurrence by Issuer and its Restricted Subsidiaries of any Existing Indebtedness or any Series Issue Date Existing Indebtedness;

(3) the incurrence by Issuer and the Subsidiary Guarantors of Indebtedness represented by the notes to be issued on the date of the supplemental indenture and the related Note Guarantees;

(4) the incurrence by Issuer or any of its Restricted Subsidiaries of Indebtedness represented by Capital Lease Obligations, mortgage financings or purchase money obligations, in each case, incurred for the purpose of financing (whether prior to or within 270 days after) all or any part of the purchase price or cost of design, construction, installation or improvement of property, plant or equipment or the Capital Stock of any Person owning such assets used in the business of Issuer or any of its Restricted Subsidiaries, in an aggregate principal amount at any time outstanding, including all Permitted Refinancing Indebtedness incurred to renew, refund, refinance, replace, defease or discharge any Indebtedness incurred pursuant to this clause (4), not to exceed the greater of (x) $2.5 billion and (y) 5.0% of Issuer’s Total Assets, at the time of any such incurrence pursuant to this clause (4);

(5) the incurrence by Issuer or any of its Restricted Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the net proceeds of which are used to renew, refund, refinance, replace, defease or discharge any Indebtedness (other than intercompany

S-91

Indebtedness) that was permitted by the indenture to be incurred under the first paragraph of this covenant or clauses (2), (3), (4), (5), (13), (14), (15), (24) or (25) of this paragraph;

(6) the incurrence by Issuer or any of its Restricted Subsidiaries of intercompany Indebtedness between or among Parent, Issuer and any of its Restricted Subsidiaries and any Guarantors; provided, however, that:

(a) if Issuer or any Subsidiary Guarantor is the obligor on such Indebtedness and the payee is not Issuer or a Guarantor, such Indebtedness must be expressly subordinated to the prior payment in full in cash of all Obligations then due with respect to the notes, in the case of Issuer, or the Note Guarantee, in the case of a Subsidiary Guarantor; and

(b) (i) any subsequent issuance or transfer of Equity Interests that results in any such Indebtedness being held by a Person other than Parent, Issuer or a Restricted Subsidiary of Issuer, or a Guarantor and (ii) any sale or other transfer of any such Indebtedness to a Person that is not either Parent, Issuer or a Restricted Subsidiary of Issuer, or a Guarantor, will be deemed, in each case, to constitute an incurrence of such Indebtedness by Issuer or such Restricted Subsidiary, as the case may be, that was not permitted by this clause (6);

(7) the issuance by any of Issuer’s Restricted Subsidiaries to Issuer or to any of its Restricted Subsidiaries of shares of Preferred Stock; provided, however, that:

(a) any subsequent issuance or transfer of Equity Interests that results in any such Preferred Stock being held by a Person other than Parent, Issuer or a Restricted Subsidiary of Issuer or a Guarantor; and

(b) any sale or other transfer of any such Preferred Stock to a Person that is not either Parent, Issuer or a Restricted Subsidiary of Issuer, or a Guarantor, will be deemed, in each case, to constitute an issuance of such Preferred Stock by such Restricted Subsidiary that was not permitted by this clause (7);

(8) the incurrence by Issuer or any of its Restricted Subsidiaries of Hedging Obligations (other than for speculative purposes);

(9) the guarantee by Issuer or any of the Subsidiary Guarantors of Indebtedness of Issuer or a Restricted Subsidiary of Issuer that was permitted to be incurred by another provision of this covenant; provided that if the Indebtedness being guaranteed is subordinated to or pari passu with the notes, then the guarantee shall be subordinated or pari passu, as applicable, to the same extent as the Indebtedness guaranteed;

(10) the incurrence by Issuer or any of its Restricted Subsidiaries of Indebtedness in respect of workers’ compensation claims, self-insurance obligations, bankers’ acceptances, deposits, performance bonds, completion bonds, bid bonds, appeal bonds and surety bonds, indemnity bonds, specific performance or injunctive relief bonds or similar bonds or obligations in the ordinary course of business, and any Guarantees or letters of credit functioning as or supporting any of the foregoing;

(11) the incurrence by Issuer or any of its Restricted Subsidiaries of Indebtedness arising from (a) the honoring by a bank or other financial institution of a check, draft or similar instrument drawn against insufficient funds, so long as such Indebtedness is covered within five business days of notice to Issuer or any of its Restricted Subsidiaries, (b) in respect of

S-92

netting, overdraft protection and other arrangements arising under standard business terms of any bank at which Issuer or any Restricted Subsidiary maintains an overdraft, cash pooling or other similar facility or arrangement or (c) in respect of the financing of insurance premiums in the ordinary course of business, provided that the aggregate principal amount of Indebtedness incurred pursuant to clauses (11)(b) and (c) shall not, at any time outstanding exceed $250.0 million;

(12) the incurrence by Issuer or any of its Restricted Subsidiaries of Indebtedness in respect of letters of credit required to be issued in connection with any Permitted Joint Venture Investment;

(13) the incurrence by Issuer or any of its Restricted Subsidiaries of Indebtedness for relocation or clearing obligations relating to Issuer’s or any of its Restricted Subsidiary’s FCC Licenses in an aggregate principal amount (or accreted value, as applicable), including all Permitted Refinancing Indebtedness incurred to renew, refund, refinance, replace, defease or discharge any Indebtedness incurred pursuant to this clause (13), at any time outstanding not to exceed $400.0 million at the time of such incurrence;

(14) the incurrence by Issuer or any of its Restricted Subsidiaries of Contribution Indebtedness;

(15) the incurrence by Issuer or any of its Restricted Subsidiaries of Indebtedness (including Acquired Debt or Indebtedness) used to finance an acquisition of or a merger with another Person, provided that, Issuer or the Person formed by or surviving any such consolidation or merger (if other than Issuer or a Restricted Subsidiary), on the date of such transaction after giving pro forma effect thereto and any related financing transactions as if the same had occurred at the beginning of the applicable four-quarter period, would either (a) be permitted to incur at least $1.00 of additional Indebtedness pursuant to the Debt to Cash Flow Ratio test set forth in the first paragraph of this covenant or (b) have a Debt to Cash Flow Ratio no greater than the Debt to Cash Flow Ratio of Issuer immediately prior to such transaction;

(16) the incurrence by Issuer or any of its Restricted Subsidiaries of Indebtedness arising from agreements providing for indemnification, adjustment of purchase price or similar obligations, or Guarantees or letters of credit, surety bonds or performance bonds securing any obligations of Issuer or any of its Restricted Subsidiaries pursuant to such agreements, in any case incurred in connection with the disposition of any business, assets or Restricted Subsidiary (other than Guarantees of Indebtedness incurred by any Person acquiring all or any portion of such business, assets or Restricted Subsidiary for the purpose of financing such acquisition), so long as the amount does not exceed the gross proceeds actually received by Issuer or any Restricted Subsidiary thereof in connection with such disposition;

(17) the incurrence by Issuer or any Restricted Subsidiary of Indebtedness constituting reimbursement obligations with respect to letters of credit issued in the ordinary course of business; provided that, upon the drawing of such letters of credit, such obligations are reimbursed within 30 days following such drawing;

(18) the incurrence by Issuer or any Restricted Subsidiary of Indebtedness to the extent that the net proceeds thereof are promptly deposited to defease or to satisfy and discharge the notes;

(19) the incurrence by Issuer or any of the Subsidiary Guarantors of additional Indebtedness in an aggregate principal amount (or accreted value, as applicable) at any time outstanding,

S-93

including all Permitted Refinancing Indebtedness incurred to renew, refund, refinance, replace, defease or discharge any Indebtedness incurred pursuant to this clause (19), not to exceed the greater of (x) $1.0 billion and (y) 2.0% of Issuer’s Total Assets as of the time of incurrence;

(20) the incurrence by Issuer or any Restricted Subsidiary of Indebtedness arising in connection with endorsement of instruments for deposit in the ordinary course of business;

(21) the incurrence by Issuer or any Restricted Subsidiary of Indebtedness evidenced by promissory notes subordinated to the notes and the Note Guarantees issued to current or former employees or directors of Parent, Issuer or any Subsidiary (or their respective spouses or estates) in lieu of cash payments for Capital Stock being repurchased from such Persons, not to exceed, in any twelve-month period, an amount equal to the amount of Restricted Payments that could be made during such twelve-month period pursuant to clause (5) of the third paragraph under the covenant described above under the caption “—Restricted Payments,” less the amount of Restricted Payments that have been made during such twelve-month period pursuant to such clause;

(22) the incurrence by Issuer or any Restricted Subsidiary of Indebtedness consisting of take-or-pay obligations contained in supply agreements entered into in the ordinary course of business;

(23) to the extent that deposits with, or payments owed to, the FCC in connection with the auction or licensing of Governmental Authorizations are deemed to be Indebtedness, the incurrence by Issuer or any Restricted Subsidiary of such Indebtedness;

(24) Indebtedness incurred in connection with the Towers Transaction; and

(25) the incurrence by Restricted Subsidiaries that are not Guarantors of Indebtedness; provided, however, that the aggregate principal amount (or accreted value, as applicable) of all Indebtedness incurred under this clause (25), when aggregated with the principal amount (or accreted value) of all other Indebtedness then outstanding and incurred pursuant to this clause (25), including all Permitted Refinancing Indebtedness incurred to renew, refund, refinance, replace, defease or discharge any Indebtedness incurred pursuant to this clause (25), does not exceed $250.0 million.

Issuer will not incur, and will not permit any Subsidiary Guarantor to incur, any Indebtedness (including Permitted Debt, but excluding Indebtedness permitted by clause (6) above) that is contractually subordinated in right of payment to any other Indebtedness of Issuer or such Subsidiary Guarantor unless such Indebtedness is also contractually subordinated in right of payment to the notes and the Note Guarantee on substantially identical terms; provided, however, that no Indebtedness shall be deemed to be contractually subordinated in right of payment to any other Indebtedness of Issuer or any Subsidiary Guarantor solely by virtue of such Indebtedness being unsecured or by virtue of such Indebtedness being secured on a first or junior Lien basis.

For purposes of (x) determining compliance with this “Incurrence of Indebtedness and Issuance of Preferred Stock” covenant, in the event that an item of proposed Indebtedness meets the criteria of more than one of the categories of Permitted Debt described in clauses (1) through (25) above, or is entitled to be incurred pursuant to the first paragraph of this covenant, Issuer will be permitted to classify all or a portion of such item of Indebtedness on the date of its incurrence, or

S-94

later reclassify all or a portion of such item of Indebtedness, in any manner that complies with this covenant and (y) determining the amount of Indebtedness that may be incurred pursuant to clause (1)(a)(y) of the definition of Permitted Debt, Issuer may elect, pursuant to an officers’ certificate delivered to the trustee, to treat all or any portion of the commitment under any Indebtedness (and any refinancing with respect thereto) as being incurred at such time, in which case any subsequent incurrence of Indebtedness under such commitment or refinancing, as the case may be, shall not be deemed, for purposes of this calculation, to be an incurrence at such subsequent time. The accrual of interest, the accretion or amortization of original issue discount, the payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms, the reclassification of Preferred Stock as Indebtedness due to a change in accounting principles or the application thereof, and the payment of dividends on Disqualified Stock in the form of additional shares of the same class of Disqualified Stock will not be deemed to be an incurrence of Indebtedness or an issuance of Disqualified Stock for purposes of this covenant. Notwithstanding any other provision of this covenant, the maximum amount of Indebtedness that Issuer or any Restricted Subsidiary may incur pursuant to this covenant shall not be deemed to be exceeded solely as a result of fluctuations in exchange rates or currency values, and in no event shall the reclassification of any lease or other liability as indebtedness due to a change in accounting principles after the Closing Date be deemed to be an incurrence of Indebtedness. In determining the amount of Indebtedness outstanding under one of the clauses above, the outstanding principal amount of any particular Indebtedness of any Person shall be counted only once and any obligation of such Person or any other Person arising under any guarantee, Lien, letter of credit or similar instrument supporting such Indebtedness shall be disregarded so long as it is permitted to be incurred by the Person or Persons incurring such obligation.

The amount of any Indebtedness outstanding as of any date will be:

(1) the accreted value of the Indebtedness, in the case of any Indebtedness issued with original issue discount;

(2) in the case of Hedging Obligations, the termination value of the agreement or arrangement giving rise to such obligations that would be payable by such Person at such time;

(3) the principal amount of the Indebtedness, in the case of any other Indebtedness; and

(4) in respect of Indebtedness of another Person secured by a Lien on the assets of the specified Person, the lesser of:

(a) the Fair Market Value of such assets at the date of determination; and

(b) the amount of the Indebtedness of the other Person.

Liens

Issuer will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, assume or suffer to exist any Lien securing Indebtedness upon any asset now owned or hereafter acquired, except Permitted Liens, unless the notes are equally and ratably secured (except that Liens securing Indebtedness that is contractually subordinated to the notes shall be expressly subordinate to any Lien securing the notes to at least the same extent that such Indebtedness is subordinate to the notes).

S-95

Dividend and other payment restrictions affecting subsidiaries

Issuer will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create or permit to exist or become effective any consensual encumbrance or restriction on the ability of any Restricted Subsidiary to:

(1) pay dividends or make any other distributions on its Capital Stock to Issuer or any of its Restricted Subsidiaries, or pay any Indebtedness owed to Issuer or any of its Restricted Subsidiaries;

(2) make loans or advances to Issuer or any of its Restricted Subsidiaries; or

(3) sell, lease or transfer any of its properties or assets to Issuer or any of its Restricted Subsidiaries.

However, the preceding restrictions will not apply to encumbrances or restrictions existing under or by reason of:

(1) agreements or instruments governing (a) Existing Indebtedness and (b) Equity Interests and Credit Facilities as in effect on the Closing Date, and, in each case, any amendments, restatements, modifications, renewals, increases, supplements, refundings, replacements or refinancings of those agreements or instruments; provided that the amendments, restatements, modifications, renewals, increases, supplements, refundings, replacements or refinancings are (in the good faith judgment of the Board of Directors of Issuer or a senior financial officer of Issuer, whose determination shall be conclusive) not materially more restrictive, taken as a whole, with respect to such dividend and other payment restrictions than those contained in those agreements or instruments on the Closing Date;

(2) agreements or instruments governing Credit Facilities not in effect on the Closing Date so long as either (a) the encumbrances and restrictions contained therein do not impair the ability of any Restricted Subsidiary of Issuer to pay dividends or make any other distributions or payments directly or indirectly to Issuer in an amount sufficient to permit Issuer to pay the principal of, or interest and premium, if any, on the notes, or (b) the encumbrances and restrictions contained therein are no more restrictive, taken as a whole, than those contained in the indenture;

(3) Series Issue Date Existing Indebtedness, the notes issued on the Series Issue Date, and any additional notes of the same series, the Note Guarantees in respect thereof, and the base indenture, as supplemented by the supplemental indenture;

(4) applicable law, rule, regulation or order;

(5) agreements or instruments with respect to a Person acquired by Issuer or any of its Restricted Subsidiaries as in effect at the time of such acquisition (except to the extent such Indebtedness or Capital Stock was incurred in connection with or in contemplation of such acquisition) or as may be amended, restated, modified, renewed, extended, supplemented, refunded, replaced or refinanced from time to time (so long as the encumbrances and restrictions in any such amendment, restatement, modification, renewal, extension, supplement, refunding, replacement or refinancing are, in the good faith judgment of Issuer’s Board of Directors or a senior financial officer of Issuer, whose determination shall be conclusive, not materially more restrictive, taken as a whole, than those in effect on the date of the acquisition), which encumbrance or restriction is not applicable to any Person,

S-96

or the properties or assets of any Person, other than the Person, or the property or assets of the Person, so acquired; provided that, in the case of agreements or instruments governing Indebtedness, such Indebtedness was permitted by the terms of the indenture to be incurred;

(6) customary non-assignment provisions in contracts and licenses entered into in the ordinary course of business and customary contractual restrictions on transfers of all or substantially all assets of a Person;

(7) any instrument governing any secured Indebtedness or Capital Lease Obligation that imposes restrictions on the assets securing such Indebtedness or the subject of such lease of the nature described in clause (3) of the preceding paragraph;

(8) any agreement for the sale or other disposition of a Restricted Subsidiary that imposes restrictions of the nature described in clauses (1) and/or (3) of the preceding paragraph on the Restricted Subsidiary pending the sale or other disposition;

(9) Permitted Refinancing Indebtedness; provided that the restrictions contained in the agreements governing such Permitted Refinancing Indebtedness are not materially more restrictive, taken as a whole, than those contained in the agreements governing the Indebtedness being refinanced;

(10) Liens permitted to be incurred under the provisions of the covenant described above under the caption “—Liens” that limit the right of the debtor to dispose of the assets subject to such Liens;

(11) provisions limiting the disposition or distribution of assets or property in partnership and joint venture agreements, asset sale agreements, sale-leaseback agreements, stock sale agreements and other similar agreements, which limitation is applicable only to the assets that are the subject of such agreements;

(12) restrictions on cash or other deposits or net worth imposed by customers, suppliers or landlords or required by insurance, surety or bonding companies, in each case, under contracts entered into in the ordinary course of business;

(13) restrictions in other Indebtedness, Disqualified Stock or Preferred Stock incurred or issued in compliance with the covenant described under the caption “—Incurrence of Indebtedness and Issuance of Preferred Stock”; provided that such restrictions, taken as a whole, are, in the good faith judgment of Issuer’s Board of Directors or a senior financial officer of Issuer, whose determination shall be conclusive, not materially more restrictive than those contained in the existing agreements referenced in clauses (1) and (3) above;

(14) the issuance of Preferred Stock by a Restricted Subsidiary of Issuer or the payment of dividends thereon in accordance with the terms thereof; provided that issuance of such Preferred Stock is permitted pursuant to the covenant described above under the caption “—Incurrence of Indebtedness and Issuance of Preferred Stock” and the terms of such Preferred Stock do not expressly restrict the ability of such Restricted Subsidiary to pay dividends or make any other distributions on its Capital Stock (other than requirements to pay dividends or liquidation preferences on such Preferred Stock prior to paying any dividends or making any other distributions on such other Capital Stock);

S-97

(15) any agreement or instrument with respect to Indebtedness incurred, or Preferred Stock issued, by any Restricted Subsidiary, provided that the restrictions contained in the agreements or instruments governing such Indebtedness or Preferred Stock (a) either (i) apply only in the event of a payment default or a default with respect to a financial covenant in such agreement or instrument or (ii) will not materially affect Issuer’s ability to pay all principal, interest and premium, if any, on the notes, as determined in good faith by Issuer’s Board of Directors or a senior financial officer of Issuer, whose determination shall be conclusive; and (b) are not materially more disadvantageous to the holders of the notes than is customary in comparable financings; and

(16) any agreement or instrument of Issuer, Parent, MetroPCS Wireless, Inc., or any of MetroPCS Wireless, Inc.’s Subsidiaries existing prior to, or entered into or assumed by Issuer or any of its Subsidiaries in connection with the Merger, in each case, as such agreements or instruments may be amended, restated, modified, renewed or replaced from time to time; provided that the amendments, restatements, modifications, renewals, and replacements are (in the good faith judgment of the Board of Directors of Issuer or a senior financial officer of Issuer, whose determination shall be conclusive) not materially more restrictive, taken as a whole, with respect to such encumbrances and restrictions than those agreements or instruments as in effect as of the Closing Date; and

(17) restrictions arising from the Towers Transaction.

Merger, consolidation or sale of assets

Issuer will not: (1) consolidate or merge with or into another Person (whether or not Issuer is the surviving corporation); or (2) directly or indirectly sell, assign, lease, transfer, convey or otherwise dispose of all or substantially all of the properties or assets of Issuer and its Restricted Subsidiaries taken as a whole, in one or more related transactions, to another Person, unless:

(1) either: (a) Issuer is the surviving corporation; or (b) the Person formed by or surviving any such consolidation or merger (if other than Issuer) or to which such sale, assignment, lease, transfer, conveyance or other disposition has been made is a corporation, limited liability company or partnership organized or existing under the laws of the United States, any state of the United States or the District of Columbia; provided that if such Person is not a corporation, such Person immediately causes a Subsidiary that is a corporation organized or existing under the laws of the United States, any state of the United States or the District of Columbia to be added as a co-issuer of the notes under the indenture;

(2) the Person formed by or surviving any such consolidation or merger (if other than Issuer) or the Person to which such sale, assignment, lease, transfer, conveyance or other disposition has been made expressly assumes, by a supplemental indenture, executed and delivered to the trustee, the payment of the principal of and any premium and interest on the notes and the performance or observance of every covenant of the indenture on the part of Issuer to be performed or observed;

(3) immediately after such transaction, no Default or Event of Default exists; and

(4) Issuer or the Person formed by or surviving any such consolidation or merger (if other than Issuer), or to which such sale, assignment, lease, transfer, conveyance or other disposition has been made would, on the date of such transaction after giving pro forma effect thereto and any related financing transactions as if the same had occurred at the beginning of the

S-98

applicable four-quarter period, either (a) be permitted to incur at least $1.00 of additional Indebtedness pursuant to the Debt to Cash Flow Ratio test set forth in the first paragraph of the covenant described above under the caption “—Incurrence of Indebtedness and Issuance of Preferred Stock” or (b) have a Debt to Cash Flow Ratio no greater than the Debt to Cash Flow Ratio of Issuer immediately prior to such transaction.

Upon any consolidation or merger, or any sale, transfer, assignment, lease, conveyance or other disposition of all or substantially all of the properties or assets of Issuer and its Restricted Subsidiaries, taken as a whole, in a transaction that is subject to, and that complies with the provisions of, this “Merger, Consolidation or Sale of Assets” covenant, the successor Person formed by such consolidation or into or with which Issuer is merged or to which such sale, transfer, assignment, lease, conveyance or other disposition is made, shall succeed to, and be substituted for Issuer (so that from and after the date of such consolidation, merger, sale, assignment, transfer, lease, conveyance or other disposition, the provisions of the indenture referring to Issuer shall refer instead to the successor Person and not to Issuer), and may exercise every right and power of Issuer under the indenture with the same effect as if such successor Person had been named as Issuer therein. When the successor Person assumes all of Issuer’s obligations under the indenture, Issuer shall be discharged from those obligations.

This “Merger, Consolidation or Sale of Assets” covenant will not apply to (and the following shall be permitted notwithstanding such covenant):

(1) a merger of Issuer with a direct or indirect Subsidiary of Parent solely for the purpose of reincorporating Issuer in another jurisdiction in the United States so long as the amount of Indebtedness of Issuer and its Restricted Subsidiaries is not increased thereby;

(2) any consolidation or merger, or any sale, assignment, transfer, conveyance, lease or other disposition of assets between or among Issuer and its Restricted Subsidiaries; or

(3) the Transactions, including the Merger.

Transactions with affiliates

Issuer will not, and will not permit any of its Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any Affiliate of Issuer (each, an “Affiliate Transaction”), in any one or series of related transactions involving aggregate payments or consideration in excess of $50.0 million, unless:

(1) the Affiliate Transaction is on terms that, taken as a whole, are no less favorable to Issuer or the relevant Restricted Subsidiary than those that would have been obtained in a comparable transaction by Issuer or such Restricted Subsidiary with an unrelated Person; and

(2) Issuer delivers to the trustee:

(a) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $100.0 million, an officers’ certificate certifying that such Affiliate Transaction complies with this covenant; and

(b) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $250.0 million, a resolution of the Board

S-99

of Directors of Issuer set forth in an officers’ certificate certifying that such Affiliate Transaction complies with this covenant and that such Affiliate Transaction has been approved by a majority of the disinterested members of the Board of Directors of Issuer.

The following items will not be deemed to be Affiliate Transactions and, therefore, will not be subject to the provisions of the prior paragraph:

(1) any employment agreement, employee benefit plan, agreement or plan relating to employee, officer or director compensation or severance, officer or director indemnification agreement or any similar arrangement entered into by Issuer, any of its Restricted Subsidiaries or a direct or indirect parent of Issuer existing on the Closing Date, or entered into thereafter in the ordinary course of business, and any indemnities or other transactions permitted or required by bylaw, statutory provisions or any of the foregoing agreements, plans or arrangements and payments pursuant thereto;

(2) transactions between or among Parent, Issuer and/or its Restricted Subsidiaries;

(3) transactions with a Person (other than an Unrestricted Subsidiary of Issuer) that is an Affiliate of Issuer solely because Issuer owns, directly or through a Restricted Subsidiary, an Equity Interest in, or controls, such Person;

(4) any issuance of Equity Interests (other than Disqualified Stock) of Issuer to, or receipt of any capital contribution from, any Affiliate of Issuer;

(5) transactions in connection with any Permitted Joint Venture Investment;

(6) any Permitted Investments or Restricted Payments that do not violate the provisions of the indenture described above under the caption “—Restricted Payments”;

(7) (x) any contracts, agreements or understandings existing as of the Issue Date and disclosed in the notes to the consolidated financial statements of MetroPCS Wireless, Inc. for the year ended December 31, 2012, (y) any agreement listed on Schedule 3.2(r)—Related-Party Agreements—to the “T-Mobile Disclosure Letter” to the Business Combination Agreement, and (z) any agreement listed under the section entitled “Transactions with Related Persons and Approval” in the proxy statement of Parent filed with the SEC under cover of Schedule 14A on April 16, 2012 and, in each case, any amendments to, replacements of, or orders pursuant to such contracts, agreements or understandings so long as any such amendments, replacements, or orders, taken as a whole, are not (in the good faith judgment of Issuer’s Board of Directors or a senior financial officer of Issuer, whose determination shall be conclusive) more disadvantageous to Issuer or to the holders of the notes in any material respect than the original contracts, agreements or understandings as in effect on the Closing Date;

(8) transactions with customers, clients, suppliers, or purchasers or sellers of goods or services, in each case in the ordinary course of business and otherwise in compliance with the terms of the indenture, provided that in the good faith determination of Issuer’s Board of Directors or a senior financial officer of Issuer, which determination shall be conclusive, such transactions are on terms, taken as a whole, not materially less favorable to Issuer or the applicable Restricted Subsidiary than those that could reasonably be expected to be obtained in a comparable transaction at such time on an arm’s length basis from a Person that is not an Affiliate of Issuer;

S-100

(9) issuances, purchases or repurchases of notes or other Indebtedness of Issuer or its Restricted Subsidiaries or solicitations of amendments, waivers or consents in respect of notes or such other Indebtedness, if such issuance, purchase, repurchase or solicitation is approved by a majority of the disinterested members of the Board of Directors of Issuer;

(10) reasonable payments made for any financial advisory, financing, underwriting, placement or syndication services approved by Issuer’s Board of Directors or a senior financial officer of Issuer in good faith;

(11) amendments, extensions, replacements and other modifications of transactions with Affiliates otherwise permitted by the indenture, provided that in the good faith determination of Issuer’s Board of Directors or a senior financial officer of Issuer, which determination shall be conclusive, such amendments, extensions, replacements or other modifications, taken as a whole, are no less favorable in any material respect to Issuer or the applicable Restricted Subsidiary than the transaction or transactions being amended, extended, replaced or modified; and

(12) (i) the Business Combination Agreement and any Ancillary Agreements, as defined in the Business Combination Agreement, in each case, as the same may be amended, modified, supplemented or replaced from time to time on terms that, taken as a whole, in the good faith determination of Issuer’s Board of Directors or a senior financial officer of Issuer, which determination shall be conclusive, are not materially less favorable to Issuer or the applicable Restricted Subsidiary than those of the agreement being amended, modified, supplemented or replaced, (ii) transactions or agreements relating to the DT Notes and the TMUS Working Capital Facility, each as may be amended, modified, or supplemented from time to time, and any indebtedness incurred in connection with the refinancing of the foregoing, on terms that, taken as a whole, in the good faith determination of Issuer’s Board of Directors or a senior financial officer of Issuer, which determination shall be conclusive, are not materially less favorable to Issuer than those of the DT Notes or TMUS Working Capital Facility, as applicable, and (iii) transactions between Issuer and its Restricted Subsidiaries, on the one hand, and any Designated Tower Entities that have been designated as Unrestricted Subsidiaries, on the other hand, in connection with the Towers Transaction.

Business activities

Issuer will not, and will not permit any of its Restricted Subsidiaries to, engage in any business other than Permitted Businesses, except to such extent as would not be material to Issuer and its Restricted Subsidiaries taken as a whole.

Additional note guarantees

If (a) Issuer or any of Issuer’s Domestic Restricted Subsidiaries acquires or creates another Domestic Restricted Subsidiary (and such Subsidiary is a Wholly-Owned Subsidiary and is neither a Designated Tower Entity, the Reinsurance Entity nor an Immaterial Subsidiary) after the Series Issue Date or (b) any Restricted Subsidiary of Issuer guarantees any Specified Issuer Indebtedness of Issuer after the Series Issue Date or (c) Parent or any Subsidiary of Parent acquires or creates a Subsidiary that directly or indirectly owns Equity Interests of Issuer, then Issuer or Parent, as applicable, will cause that newly acquired or created Domestic Restricted Subsidiary, Restricted

S-101

Subsidiary or Subsidiary of Parent to become a Guarantor of the notes and execute a supplemental indenture and, if requested by the trustee, deliver an opinion of counsel reasonably satisfactory to the trustee within 10 business days after the date on which it was acquired or created or guarantees such Specified Issuer Indebtedness, as applicable, or reasonably promptly thereafter.

Designation of restricted and unrestricted subsidiaries

The Board of Directors of Issuer may designate any Restricted Subsidiary to be an Unrestricted Subsidiary if that designation would not cause a Default. If a Restricted Subsidiary is designated as an Unrestricted Subsidiary, (i) the aggregate Fair Market Value of all outstanding Investments owned by Issuer and its Restricted Subsidiaries in the Subsidiary designated as an Unrestricted Subsidiary will be deemed to be an Investment made as of the time of the designation and will reduce the amount available for Restricted Payments under the covenant described above under the caption “—Restricted Payments” or under one or more clauses of the definition of Permitted Investments, as determined by Issuer in its discretion, and (ii) any Guarantee by Issuer or any Restricted Subsidiary thereof of any Indebtedness of the Restricted Subsidiary being so designated will be deemed to be an incurrence of Indebtedness by Issuer or such Restricted Subsidiary (or both, if applicable) at the time of such designation. That designation will only be permitted if the Investment and/or incurrence of Indebtedness would be permitted at that time and if the Restricted Subsidiary otherwise meets the definition of an Unrestricted Subsidiary. The Board of Directors of Issuer may redesignate any Unrestricted Subsidiary to be a Restricted Subsidiary if that redesignation would not cause a Default.

Any designation of a Subsidiary of Issuer as an Unrestricted Subsidiary will be evidenced to the trustee by filing with the trustee a certified copy of a resolution of the Board of Directors giving effect to such designation and an officers’ certificate certifying that such designation complied with the preceding conditions and was permitted by the covenant described above under the caption “—Restricted Payments.” The Board of Directors of Issuer may at any time designate any Unrestricted Subsidiary to be a Restricted Subsidiary of Issuer; provided that such designation will be deemed to be an incurrence of Indebtedness by a Restricted Subsidiary of Issuer of any outstanding Indebtedness of such Unrestricted Subsidiary, and such designation will only be permitted if (1) such Indebtedness is permitted under the covenant described under the caption “—Incurrence of Indebtedness and Issuance of Preferred Stock,” calculated on a pro forma basis as if such designation had occurred at the beginning of the four-quarter reference period; and (2) no Default would be in existence following such designation, and as a result of, such designation.

Notwithstanding the foregoing, Issuer may at any time and from time to time designate any Designated Entity, by written notice to the trustee, as an Unrestricted Subsidiary, and any such Subsidiary shall upon such notice immediately be designated and deemed an Unrestricted Subsidiary, without any further action by Issuer (and, for the avoidance of doubt, shall not require delivery of a resolution of the Board of Directors or of an officers’ certificate) (each, a “Specified Unrestricted Subsidiary Designation”). The aggregate Fair Market Value of all outstanding Investments owned by Issuer and its Restricted Subsidiaries in such Designated Entities so designated as Unrestricted Subsidiaries will, as calculated and to the extent permitted by clause (18) of the definition of Permitted Investments, be deemed to be an Investment made as of the time of such Specified Unrestricted Subsidiary Designation under such clause (18), and not reduce the amount available for Restricted Payments under the covenant described above under the caption “—Restricted Payments.”

S-102

Payments for consent

Issuer will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, pay or cause to be paid any consideration to or for the benefit of any holder of either series of notes for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of the applicable indenture with respect to such notes or such notes unless such consideration is offered to be paid and is paid to all holders of such series of notes that consent, waive or agree to amend in the time frame set forth in the solicitation documents relating to such consent, waiver or amendment.

Reports

Whether or not required by the rules and regulations of the SEC, so long as any notes are outstanding, Parent will file a copy of each of the reports referred to in clauses (1) and (2) below with the SEC for public availability within the time periods (including all applicable extension periods) specified in the SEC rules and regulations applicable to such reports (unless the SEC will not accept such a filing):

(1) all quarterly and annual financial reports that would be required to be contained in a filing with the SEC on Forms 10-Q and 10-K if Parent were required to file such reports, including a “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and, with respect to the annual information only, a report on the annual financial statements by its certified independent accountants; and

(2) all current reports that would be required to be filed with the SEC on Form 8-K if Parent or Issuer were required to file such reports;

provided that the availability of the foregoing reports on the SEC’s EDGAR service (or successor thereto) shall be deemed to satisfy Issuer’s delivery obligations to the trustee and any holder of notes.

All such reports will be prepared in all material respects in accordance with all of the rules and regulations applicable to such reports; provided that, if neither Parent nor Issuer is required under the rules and regulations of the SEC to file such reports with the SEC for public availability, such reports need not be prepared in accordance with all of the rules and regulations applicable to such reports and shall only be required to include the information or disclosure that would be required by such form to the extent that, and in the same general style of presentation as, the same or substantially similar information or disclosure is also included in the offering memorandum dated March 8, 2013 relating to the $3.5B Notes. Each annual report on Form 10-K will include a report on Parent’s consolidated financial statements by Parent’s certified independent accountants. Issuer will at all times comply with TIA §314(a).

If the SEC will not accept Parent’s or Issuer’s filings for any reason, Parent or Issuer will post the reports referred to in the preceding paragraphs on its website, on intralinks.com or another website within the time periods that would apply if Parent were required to file those reports with the SEC (including all applicable extension periods). If (i) Issuer has designated any of its Subsidiaries as Unrestricted Subsidiaries or (ii) the combined operations of Parent and its Subsidiaries, excluding the operations of Issuer and its Restricted Subsidiaries and excluding cash and Cash Equivalents, would, if held by a single Unrestricted Subsidiary of Issuer, constitute a Significant Subsidiary of Issuer, then the quarterly and annual financial information required by the preceding paragraphs will include a reasonably detailed presentation, either on the face of the financial statements or in the footnotes thereto, and in Management’s Discussion and Analysis of Financial Condition and Results of Operations, of (A) in the case of (i) above, the

financial condition and results of operations of Parent, Issuer and its Restricted Subsidiaries separate from the financial condition and results of operations of the Unrestricted Subsidiaries of Issuer and (B) in the case of (ii) above, the financial condition and results of operations of Issuer and its Restricted Subsidiaries separate from the financial condition and results of operations of Parent and its other Subsidiaries; provided, however, that the requirements of this paragraph shall not apply if Parent or Issuer files with the SEC the reports referred to in clauses (1) and (2) of the first paragraph of this covenant, and any such report contains the information required in this paragraph.

For so long as any notes remain outstanding, if at any time they are not required to file with the SEC the reports required by the preceding paragraphs, Issuer and the Guarantors will furnish to the holders of notes and to securities analysts and prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act.

Events of default and remedies

Each of the following is an “Event of Default” in respect of the notes of a series:

(1) default for 30 days in the payment when due of interest on the notes of such series;

(2) default in the payment when due (at maturity, upon redemption or otherwise) of the principal of, or premium, if any, on, the notes of such series;

(3) failure by Issuer for 120 days after notice to Issuer by the trustee or the holders of at least 25% in aggregate principal amount of the notes of such series then outstanding voting as a single class to comply with the provisions described under the caption “—Reports”;

(4) failure by Issuer or any of its Restricted Subsidiaries for 30 days after notice to Issuer by the trustee or the holders of at least 25% in aggregate principal amount of the notes of such series then outstanding voting as a single class to comply with the provisions described under the captions “—Repurchase at the Option of Holders—Change of Control Triggering Event” or “—Repurchase at the Option of Holders—Asset Sales” (in each case other than a failure to purchase notes that will constitute an Event of Default under clause (2) above), or “—Certain Covenants—Merger, Consolidation or Sale of Assets”;

(5) failure by Issuer or any of its Restricted Subsidiaries for 90 days after notice to Issuer by the trustee or the holders of at least 25% in aggregate principal amount of the notes of such series then outstanding voting as a single class to comply with any of the other agreements in the indenture;

(6) default under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness for money borrowed by Issuer or any of its Restricted Subsidiaries that is a Significant Subsidiary (or any Restricted Subsidiaries that together would constitute a Significant Subsidiary) (or the payment of which is guaranteed by Issuer or any of its Restricted Subsidiaries that would constitute a Significant Subsidiary), whether such Indebtedness or Guarantee now exists, or is created after the Series Issue Date with respect to such series of notes, if that default:

(a) is caused by a failure to pay principal of, or interest or premium, if any, on, such Indebtedness prior to the expiration of the grace period provided in such Indebtedness on the date of such default (a “Payment Default”); or

(b) results in the acceleration of such Indebtedness prior to its express maturity;

S-104

and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a Payment Default or the maturity of which has been so accelerated, aggregates an amount equal to $100.0 million or more, in each case for so long as such failure or acceleration is continuing;

(7) failure by Issuer or any of its Restricted Subsidiaries that is a Significant Subsidiary (or any Restricted Subsidiaries that together would constitute a Significant Subsidiary) to pay or discharge final judgments entered by a court or courts of competent jurisdiction aggregating in excess of $100.0 million (to the extent not covered by insurance), which judgments are not paid, discharged or stayed for a period of 60 consecutive days following entry of such final judgment or decree during which a stay of enforcement of such final judgment or decree, by reason of pending appeal or otherwise, is not in effect;

(8) Issuer or any of its Restricted Subsidiaries that is a Significant Subsidiary, or any group of Restricted Subsidiaries of Issuer that, taken together, would constitute a Significant Subsidiary, pursuant to or within the meaning of Bankruptcy Law:

(a) commences a voluntary case,

(b) consents to the entry of an order for relief against it in an involuntary case,

(c) consents to the appointment of a custodian of it or for all or substantially all of its property,

(d) makes a general assignment for the benefit of its creditors, or

(e) generally is not paying its debts as they become due;

(9) a court of competent jurisdiction enters a final order or decree under any Bankruptcy Law that:

(a) is for relief against Issuer or any of its Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted Subsidiaries of Issuer that, taken together, would constitute a Significant Subsidiary in an involuntary case;

(b) appoints a custodian of Issuer or any of its Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted Subsidiaries of Issuer that, taken together, would constitute a Significant Subsidiary or for all or substantially all of the property of Issuer or any of its Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted Subsidiaries of Issuer that, taken together, would constitute a Significant Subsidiary; or

(c) orders the liquidation of Issuer or any of its Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted Subsidiaries of Issuer that, taken together, would constitute a Significant Subsidiary;

and the final order or decree remains unstayed and in effect for 60 consecutive days; and

(10) except as permitted by the indenture, any Note Guarantee with respect to the notes of such series is held in any judicial proceeding to be unenforceable or invalid or ceases for any reason to be in full force and effect, or any Guarantor, or any Person acting on behalf of any such Guarantor, denies or disaffirms its obligations under its Note Guarantee.

S-105

In the case of an Event of Default arising from certain events of bankruptcy or insolvency, with respect to Issuer, any Restricted Subsidiary of Issuer that is a Significant Subsidiary or any group of Restricted Subsidiaries of Issuer that, taken together, would constitute a Significant Subsidiary, all outstanding notes of such series will become due and payable immediately without further action or notice. However, the effect of such provisions may be limited by applicable laws. If any other Event of Default occurs and is continuing with respect to either series of notes, the trustee or the holders, with a copy to the trustee, of at least 25% in aggregate principal amount of the then outstanding notes of such series may declare all the notes of such series to be due and payable immediately.

Subject to certain limitations, the holders of a majority in aggregate principal amount of the then outstanding notes of a series may direct the trustee in its exercise of any trust or power. The trustee may withhold from holders of the notes notice of any continuing Default or Event of Default if it determines that withholding notice is in their interest, except a Default or Event of Default in the payment of interest or premium, if any, on, or the principal of, the notes of such series.

Subject to the provisions of the indenture relating to the duties of the trustee, the trustee will be under no obligation to exercise any of the rights or powers under the indenture at the request or direction of any holders of notes unless such holders have offered to the trustee indemnity or security satisfactory to it against any loss, liability or expense.

Except to enforce the right to receive payment of principal, premium, if any, or interest when due, no holder of a note may pursue any remedy with respect to the indenture or the notes unless:

(1) such holder has previously given to the trustee written notice that an Event of Default is continuing;

(2) holders of at least 25% in aggregate principal amount of the then outstanding notes of the applicable series have made a written request to the trustee to institute proceedings in respect of such Event of Default in its own name as trustee;

(3) such holder or holders have offered the trustee security or indemnity satisfactory to it against any loss, liability or expense to be incurred in compliance with such request;

(4) the trustee has not complied with such request within 90 days after receipt of the request and the offer of security or indemnity; and

(5) during such 90-day period, holders of a majority in aggregate principal amount of the then outstanding notes of the applicable series have not given the trustee a direction inconsistent with such request.

The holders of a majority in aggregate principal amount of the then outstanding notes of a series by written notice to the trustee may, on behalf of the holders of all of the notes of such series, rescind an acceleration or waive any existing Default or Event of Default in respect of such series and its consequences under the indenture except a continuing Default or Event of Default in the payment of interest or premium, if any, on, or the principal of, the notes of such series.

In the case of any Event of Default occurring by reason of any willful action (or inaction) taken (or not taken) by or on behalf of Issuer with the intention of avoiding payment of the premium that Issuer would have had to pay if Issuer then had elected to redeem the notes pursuant to the

S-106

optional redemption provisions of the indenture, an equivalent premium will also become and be immediately due and payable to the extent permitted by law upon the acceleration of the notes of such series.

Issuer is required to deliver to the trustee annually a statement regarding compliance with the indenture. Upon becoming aware of any Default or Event of Default, Issuer is required to deliver to the trustee a statement specifying such Default or Event of Default.

No personal liability of directors, officers, employees and stockholders

No past, present or future director, officer, member, manager, partner, employee, incorporator or stockholder of Issuer or any Guarantor, as such, will have any liability for any obligations of Issuer or the Guarantors under the notes, the indenture, the Note Guarantees, or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each holder of notes by accepting a note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the notes. The waiver may not be effective to waive liabilities under the federal securities laws.

Legal defeasance and covenant defeasance

Issuer may at any time, at the option of its Board of Directors evidenced by a resolution set forth in an officers’ certificate, elect to have all of its obligations discharged with respect to the outstanding notes of either series and all obligations of the Guarantors discharged with respect to their Note Guarantees with respect to such series (“Legal Defeasance”) except for:

(1) the rights of holders of outstanding notes of such series to receive payments in respect of the principal of, or interest or premium, if any, on, the notes when such payments are due from the trust referred to below;

(2) Issuer’s obligations with respect to the notes of such series concerning issuing temporary notes, registration of notes, mutilated, destroyed, lost or stolen notes and the maintenance of an office or agency for payment of money for security payments held in trust;

(3) the rights, powers, trusts, duties, indemnities and immunities of the trustee, and Issuer’s and the Guarantors’ obligations in connection therewith; and

(4) the Legal Defeasance and Covenant Defeasance provisions of the indenture.

In addition, Issuer may, at its option and at any time with respect to either series of notes, elect to have the obligations of Issuer and the Guarantors released with respect to the provisions of the indenture described above under “—Repurchase at the Option of Holders” and under the caption “—Certain Covenants” (other than the covenant described under the caption “—Certain Covenants—Merger, Consolidation or Sale of Assets,” except to the extent described below) and the limitation imposed by clause (4) under the caption “—Certain Covenants—Merger, Consolidation or Sale of Assets” (such release and termination being referred to as “Covenant Defeasance”), and thereafter any omission to comply with such obligations or provisions will not constitute a Default or Event of Default with respect to such notes. In the event Covenant Defeasance occurs with respect to either series of notes in accordance with the indenture, the Events of Default described under clauses (3) through (9) under the caption “—Events of Default and Remedies” (in the case of clauses (8) and (9), only with respect to Issuer’s Subsidiaries), in each case, will no longer constitute an Event of Default.

S-107

In order to exercise either Legal Defeasance or Covenant Defeasance with respect to either series of notes:

(1) Issuer must irrevocably deposit with the trustee or its designee, in trust, for the benefit of the holders of such series of notes, cash in U.S. dollars, non-callable Government Securities, or a combination of cash in U.S. dollars and non-callable Government Securities, in such amounts as will be sufficient, in the opinion of a nationally recognized investment bank, appraisal firm or firm of independent public accountants, to pay the principal of, and premium, if any, and interest on, the outstanding notes of such series on the stated date for payment thereof or on the applicable redemption date, as the case may be, and Issuer must specify whether such notes are being defeased to such stated date for payment or to a particular redemption date;

(2) in the case of Legal Defeasance, Issuer must deliver to the trustee an opinion of counsel reasonably acceptable to the trustee (which opinion of counsel may be subject to customary assumptions, qualifications and exclusions) confirming that (a) Issuer has received from, or there has been published by, the Internal Revenue Service a ruling or (b) since the Closing Date, there has been a change in the applicable U.S. federal income tax law, in either case to the effect that, and based thereon such opinion of counsel shall confirm that, the holders of the outstanding notes of such series will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such Legal Defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred;

(3) in the case of Covenant Defeasance, Issuer must deliver to the trustee an opinion of counsel reasonably acceptable to the trustee confirming that the holders of the outstanding notes of such series will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such Covenant Defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred;

(4) no Default or Event of Default has occurred and is continuing with respect to such series of notes on the date of such deposit (other than a Default or Event of Default resulting from the borrowing of funds, or the imposition of Liens in connection therewith, to be applied to such deposit, or a Default or Event of Default that will be cured by such Covenant Defeasance or Legal Defeasance) and the deposit will not result in a breach or violation of, or constitute a default under, any material instrument to which Issuer or any Guarantor is a party or by which Issuer or any Guarantor is bound;

(5) such Legal Defeasance or Covenant Defeasance will not result in a breach or violation of, or constitute a default under, any material agreement or instrument (other than the indenture) to which Issuer or any of its Subsidiaries is a party or by which Issuer or any of its Subsidiaries is bound;

(6) Issuer must deliver to the trustee an officers’ certificate stating that the deposit was not made by Issuer with the intent of preferring the holders of notes over the other creditors of Issuer with the intent of defeating, hindering, delaying or defrauding any creditors of Issuer or others;

(7) Issuer must deliver to the trustee an officers’ certificate, stating that all conditions precedent relating to the Legal Defeasance or the Covenant Defeasance have been complied with; and

S-108

(8) Issuer must deliver to the trustee an opinion of counsel (which may be subject to customary assumptions, qualifications and exclusions), stating that all conditions precedent set forth in clauses (2), (3) and (5) of this paragraph, as applicable, have been complied with; provided that the opinion of counsel with respect to clause (5) of this paragraph may be to the knowledge of such counsel.

Amendment, supplement and waiver

Except as provided in the next two succeeding paragraphs, the applicable indenture with respect to the notes of either series or the notes of either series or the related Note Guarantees of the notes of either series may be amended or supplemented with the consent of the holders of at least a majority in aggregate principal amount of the notes of such series then outstanding (including consents obtained in connection with a purchase of, or tender offer or exchange offer for, notes of such series), and any existing Default or Event of Default or compliance with any provision of the applicable indenture with respect to such notes or Note Guarantees may be waived with the consent of the holders of a majority in aggregate principal amount of the then outstanding notes of such series (including consents obtained in connection with a purchase of, or tender offer or exchange offer for, the notes of such series).

Without the consent of each holder of notes of the applicable series affected, an amendment, supplement or waiver may not (with respect to any notes of a particular series held by a non-consenting holder):

(1) reduce the principal amount of notes of such series whose holders must consent to an amendment, supplement or waiver;

(2) reduce the principal of or change the fixed maturity of any note of such series or alter the provisions with respect to the redemption of the notes of such series (other than provisions relating to the covenants described above under the caption “—Repurchase at the Option of Holders”);

(3) reduce the rate of or change the time for payment of interest on any note of such series;

(4) waive a Default or Event of Default in the payment of principal of, or premium, if any, or interest on, the notes of such series (except a rescission of acceleration of the notes of such series by the holders of at least a majority in aggregate principal amount of the then outstanding notes of such series and a waiver of the payment default that resulted from such acceleration);

(5) make any note of such series payable in money other than that stated in the notes of such series;

(6) make any change in the provisions of the indenture relating to waivers of past Defaults or the rights of holders of notes of such series to receive payments of principal of, or interest or premium, if any, on, the notes of such series;

(7) waive a redemption payment with respect to any note of such series (other than a payment required by one of the covenants described above under the caption “—Repurchase at the Option of Holders”);

(8) release any Guarantor from any of its obligations under its related Note Guarantee of the notes of such series or the applicable indenture, except in accordance with the terms of such indenture; or

(9) make any change in the preceding amendment and waiver provisions.

S-109

Notwithstanding the preceding, without the consent of any holder of notes, Issuer, the Guarantors and the trustee may amend or supplement the applicable indenture, the notes of either series or the related Note Guarantees:

(1) to cure any ambiguity, defect or inconsistency;

(2) to provide for uncertificated notes in addition to or in place of certificated notes;

(3) to provide for the assumption of Issuer’s or a Guarantor’s obligations to holders of notes of such series and related Note Guarantees in the case of a merger or consolidation or sale of all or substantially all of Issuer’s or such Guarantor’s assets, as applicable;

(4) to effect the release of a Guarantor from its Note Guarantee in respect of such series of notes and the termination of such Note Guarantee, all in accordance with the provisions of the applicable indenture governing such release and termination;

(5) to add any Guarantor or Note Guarantee with respect to such series or to secure the notes of such series or the related Note Guarantee;

(7) to comply with requirements of the SEC in order to effect or maintain the qualification of the indenture under the Trust Indenture Act;

(8) to change or eliminate any of the provisions of the applicable indenture; provided that any such change or elimination shall not become effective with respect to any outstanding notes of any series created prior to the execution of such supplemental indenture which is entitled to the benefit of such provision;

(9) to provide for the issuance of and establish forms and terms and conditions of a new series of notes as permitted by the base indenture;

(10) to conform the text of the applicable supplemental indenture, the notes of such series, or the related Note Guarantees to any provision of the “Description of Notes” section of this prospectus supplement to the extent that such provision in such description of notes was intended to be a verbatim recitation of a provision of the applicable indenture, the applicable Note Guarantees, or the notes of such series, in each case, as conclusively evidenced by an officers’ certificate;

(11) to provide for the issuance of additional notes of such series, provided that such additional notes have the same terms as, and be deemed part of the same series as, the notes of such series to the extent required under the applicable indenture;

(12) to evidence and provide for the acceptance of and appointment by a successor trustee with respect to the notes of such series and to add to or change any of the provisions of the indenture as shall be necessary to provide for or facilitate the administration of the trust by more than one trustee; and

(13) to allow any Guarantor of the notes of such series to execute a supplemental indenture and/or a Note Guarantee with respect to the notes of such series.

S-110

The consent of the holders of the notes is not necessary under the indenture to approve the particular form of any proposed amendment or waiver. It is sufficient if such consent approves the substance of the proposed amendment or waiver.

Satisfaction and discharge

The applicable indenture will be discharged and will cease to be of further effect as to all notes, when:

(1) either:

(a) all notes of such series that have been authenticated, except lost, stolen or destroyed notes that have been replaced or paid and notes for whose payment money has been deposited in trust and thereafter repaid to Issuer, have been delivered to the trustee for cancellation; or

(b) all notes of such series that have not been delivered to the trustee for cancellation have become due and payable by reason of the sending of a notice of redemption or otherwise or will become due and payable within one year and Issuer or any Guarantor has irrevocably deposited or caused to be deposited with the trustee or its designee as trust funds in trust solely for the benefit of the holders of such series of notes, cash in U.S. dollars, non-callable Government Securities, or a combination of cash in U.S. dollars and non-callable Government Securities, in such amounts as will be sufficient, without consideration of any reinvestment of interest, to pay and discharge the entire Indebtedness on the notes of such series not delivered to the trustee for cancellation for principal of, and premium, if any, and accrued interest to the date of maturity or redemption;

(2) no Default or Event of Default has occurred and is continuing with respect to the notes of such series on the date of such deposit (other than a Default or Event of Default resulting from the borrowing of funds, or the imposition of any Liens in connection therewith, to be applied to such deposit, or a Default or Event of Default that will be cured by such discharge);

(3) such deposit will not result in a breach or violation of, or constitute a default under, any material agreement or instrument (other than the indenture) to which Issuer or any Guarantor is a party or by which Issuer or any Guarantor is bound;

(4) Issuer or any Guarantor has paid or caused to be paid all sums payable by it under the indenture with respect to the notes of such series; and

(5) Issuer has delivered irrevocable instructions to the trustee under the indenture to apply the deposited money toward the payment of the notes of such series at maturity or on the redemption date, as the case may be.

In addition, Issuer must deliver to the trustee (a) an officers’ certificate, stating that all conditions precedent set forth in clauses (1) through (5) above have been satisfied, and (b) an opinion of counsel (which opinion of counsel may be subject to customary assumptions and qualifications), stating that all conditions precedent set forth in clauses (3) and (5) above have been satisfied; provided that the opinion of counsel with respect to clause (3) above may be to the knowledge of such counsel.

S-111

Governing law

The indenture, the notes and the Note Guarantees will be governed by the laws of the State of New York.

Concerning the trustee

We maintain ordinary banking relationships with Deutsche Bank Trust Company Americas and its affiliates.

If the trustee becomes a creditor of Issuer or any Guarantor, the indenture limits the right of the trustee to obtain payment of claims in certain cases, or to realize on certain property received in respect of any such claim as security or otherwise. The trustee will be permitted to engage in other transactions; however, if it acquires any conflicting interest when a Default is continuing it must eliminate such conflict within 90 days of the date such conflict arises, apply to the SEC for permission to continue as trustee (if the indenture has been qualified under the Trust Indenture Act) or resign.

The holders of a majority in aggregate principal amount of the then outstanding notes of the applicable series will have the right to direct the time, method and place of conducting any proceeding for exercising any remedy available to the trustee, subject to certain exceptions. The indenture provides that in case an Event of Default occurs and is continuing, the trustee will be required, in the exercise of its power, to use the degree of care of a prudent man in the conduct of his own affairs.

Subject to such provisions, the trustee will be under no obligation to exercise any of its rights or powers under the indenture at the request of any holder of notes of the applicable series, unless such holder has offered to the trustee security and indemnity satisfactory to it against any loss, liability or expense.

S-138

Certain U.S. federal income tax considerations

The following is a summary of certain U.S. federal income tax considerations that may be relevant to the purchase, ownership and disposition of the notes. This summary is limited to holders that acquire their notes at original issuance for cash at the first price at which a substantial portion of the notes is sold for cash to persons other than bond houses, brokers, or similar persons or organizations acting in the capacity of underwriters, placement agents or wholesalers. It is expected, and this discussion assumes, that the notes will not be issued with original issue discount for U.S. federal income tax purposes. This summary is based upon the Internal Revenue Code of 1986, as amended (the “Code”), U.S. Treasury regulations issued thereunder, rulings and pronouncements of the Internal Revenue Service (the “IRS”) and judicial decisions, all as in effect on the date hereof, and all of which are subject to change or differing interpretations, possibly with retroactive effect. This summary does not discuss all aspects of U.S. federal income taxation that may be important to particular investors in light of their individual circumstances or to holders subject to special tax rules, such as banks and other financial institutions, insurance companies, broker-dealers, holders liable for the alternative minimum tax, traders in securities that elect mark-to-market tax treatment, U.S. expatriates, tax-exempt entities, persons that will hold the notes as a part of a straddle, hedge, conversion, constructive sale or other integrated transaction for U.S. federal income tax purposes, entities or arrangements treated as partnerships for U.S. federal income tax purposes and partners in such partnerships and U.S. Holders (as defined below) whose functional currency is not the U.S. dollar. In addition, this summary does not discuss any foreign, state or local tax considerations or any U.S. federal tax considerations other than income tax considerations, such as estate or gift tax considerations. This summary applies only to investors that will hold their notes as “capital assets” within the meaning of Section 1221 of the Code (generally, property held for investment).

For purposes of this summary, a “U.S. Holder” is a beneficial owner of a note that, for U.S. federal income tax purposes, is (i) an individual who is a citizen or resident of the United States, (ii) a corporation, or other entity treated as a corporation for U.S. federal income tax purposes, created or organized under the laws of the United States or any state thereof or the District of Columbia, (iii) an estate, the income of which is subject to U.S federal income tax regardless of its source, or (iv) a trust, (A) the administration of which is subject to the primary supervision of a U.S. court and with respect to which one or more U.S. persons have the authority to control all substantial decisions or (B) that has in effect a valid election under applicable U.S. Treasury regulations to be treated as a U.S. person for U.S. federal income tax purposes. A beneficial owner of a note that is not a U.S. Holder or a partnership for U.S. federal income tax purposes is referred to herein as a “Non-U.S. Holder.”

If an entity or arrangement treated as a partnership for U.S. federal income tax purposes is a beneficial owner of notes, the treatment of a partner in the partnership will generally depend upon the status of the partner and the activities of the partnership. A partnership considering an investment in the notes and partners in such a partnership should consult their own tax advisors about the U.S. federal income tax consequences of the purchase, ownership and disposition of notes.

We have not sought and will not seek any rulings from the IRS, with respect to the matters discussed below. There can be no assurance that the IRS will not take a different position concerning the tax consequences of the purchase, ownership or disposition of the notes or that any such position would not be sustained.

S-139

Prospective investors should consult their own tax advisors with regard to the application of the U.S. federal income tax consequences discussed below to their particular situations, as well as the application of any state, local, or foreign tax laws, or other U.S. federal tax laws, including gift and estate tax laws.

The terms of the notes provide for payments by us in excess of stated interest or principal on the notes, or prior to their scheduled payment dates, under certain circumstances. The possibility of such payments may implicate special rules under the U.S. Treasury regulations governing “contingent payment debt instruments.” According to those U.S. Treasury regulations, the possibility that certain payments in excess of stated interest or principal, or prior to their scheduled payment dates, will be made will not cause the notes to be treated as contingent payment debt instruments, if there is only a remote chance as of the date the notes were issued that any such payments will be made. We intend to take the position that, as of the issue date, the likelihood that we will pay any such excess or accelerated amounts is remote within the meaning of the applicable U.S. Treasury regulations. Our position that the notes are not contingent payment debt instruments is binding on a holder unless such holder discloses its contrary position to the IRS in the manner required by applicable U.S. Treasury regulations. Our position is not, however, binding on the IRS, and if the IRS were to challenge this position successfully, a holder might be required, among other things, to (1) accrue interest income based on a projected payment schedule and comparable yield, which may be in excess of stated interest on the notes and (2) treat as ordinary income, rather than capital gain, any income realized on a sale, exchange, redemption or other taxable disposition of a note. In the event a contingency described above occurs, it may affect the amount, timing and character of the income or loss recognized by a holder. The remainder of this discussion assumes that the notes will not be contingent payment debt instruments.

U.S. Holders

Stated Interest.    A U.S. Holder must generally include stated interest on a note in income as ordinary income at the time such interest is received or accrued, in accordance with such U.S. Holder’s regular method of accounting for U.S. federal income tax purposes.

Sale, exchange, retirement or other taxable disposition of notes.    Upon a sale, exchange, retirement or other taxable disposition of notes, a U.S. Holder will generally recognize gain or loss in an amount equal to the difference, if any, between (i) the amount of cash and the fair market value of any property received on such disposition (other than any cash or property attributable to accrued but unpaid stated interest, which will be treated as interest as described above under “—Stated Interest” to the extent not previously included in income) and (ii) the U.S. Holder’s tax basis in such notes. A U.S. Holder’s tax basis in a note will generally equal the cost of the note to such U.S. Holder. Any such gain or loss generally will be treated as capital gain or loss and will be treated as long-term capital gain or loss if the U.S. Holder’s holding period for the notes exceeds one year at the time of the disposition. Long-term capital gains of non-corporate taxpayer are subject to reduced rates of taxation. The deductibility of capital losses is subject to limitations.

Additional tax on net investment income.    For taxable years beginning after December 31, 2012, certain U.S. Holders that are not corporations and whose income exceeds certain thresholds will generally be subject to a 3.8% tax (the “Medicare tax”) on their “net investment income” for the taxable year. A U.S. Holder’s net investment income will generally include any interest income or gain recognized by such U.S. Holder with respect to the notes, unless such interest income or gain

S-140

is derived in the ordinary course of the conduct of such U.S. Holder’s trade or business (other than a trade or business that consists of certain passive or trading activities). Prospective U.S. Holders that are not corporations should consult their own tax advisors with respect to the application of the Medicare tax to their purchase, ownership and disposition of notes.

Non-U.S. Holders

Interest.    Subject to the discussion under “—Information Reporting and Backup Withholding” below, payments of interest on the notes to a Non-U.S. Holder generally will be exempt from U.S. federal income tax and U.S. federal income tax withholding, provided that: (i) such Non-U.S. Holder does not own, actually or constructively, 10% or more of the total combined voting power of all classes of our stock entitled to vote, (ii) such Non-U.S. Holder is not a “controlled foreign corporation” with respect to which we are a “related person” (as provided in Section 864(d)(4) of the Code), (iii) such interest is not effectively connected with the conduct by the Non-U.S. Holder of a trade or business within the United States, and (iv) the Non-U.S. Holder certifies, under penalties of perjury, on IRS Form W-8BEN (or appropriate substitute form) that it is not a “U.S. person” (as defined in the Code) and provides its name, address and certain other required information, or certain other certification requirements are satisfied.

If a Non-U.S. Holder cannot satisfy the requirements described above, payments of interest on the notes made to such Non-U.S. Holder will generally be subject to U.S. federal income tax withholding at a 30% rate (or such lower rate as may be specified by an applicable income tax treaty), unless such interest is effectively connected with the conduct by such Non-U.S. Holder of a trade or business within the United States (unless an applicable income tax treaty provides otherwise) and such Non-U.S. Holder provides a properly completed and executed IRS Form W-8ECI (or other applicable form). In order to claim a reduced rate of or exemption from U.S. federal income tax withholding under an applicable income tax treaty, a Non-U.S. Holder generally must complete IRS Form W-8BEN and claim this reduction or exemption on the form prior to the payment date. A Non-U.S. Holder eligible for an exemption from or reduced rate of U.S. federal income tax withholding under an applicable income tax treaty may obtain a refund of any excess amounts withheld by timely filing an appropriate claim for refund with the IRS. Non-U.S. Holders should consult their own tax advisors regarding their entitlement to benefits under an applicable income tax treaty and the requirements for claiming any such benefits.

If interest on the notes is effectively connected with the conduct by a Non-U.S. Holder of a trade or business within the United States, such interest will generally not be subject to U.S. federal income tax withholding (unless an applicable income tax treaty provides otherwise) provided that the Non-U.S. Holder complies with applicable certification and other requirements. Instead, unless an applicable income tax treaty provides otherwise, such interest generally will be subject to U.S. federal income tax on a net income basis at the rates applicable to U.S. persons generally (and, with respect to corporate Non-U.S. Holders, an additional “branch profits tax” (at a 30% rate or lower rate specified by an applicable income tax treaty) may apply to any “effectively connected earnings and profits” (subject to adjustments)).

Sale, exchange, retirement or other taxable disposition of notes.    Subject to the discussion below under “—Information Reporting and Backup Withholding” concerning backup withholding and except with respect to accrued but unpaid interest, which will be taxable as described above under “Interest,” a Non-U.S. Holder will not generally be subject to U.S. federal income tax or withholding of such tax on any gain realized upon a sale, exchange, retirement or other taxable

S-141

disposition of a note, unless (i) such gain is effectively connected with the conduct by such Non-U.S. Holder of a trade or business within the United States (and, if required by an applicable treaty, is attributable to a permanent establishment or fixed base maintained by the Non-U.S. Holder within the United States), in which case, such gain will be subject U.S. federal income tax on a net income basis at the rates applicable to U.S. persons generally (and, with respect to corporate Non U.S.-Holders, an additional “branch profits tax” (at a 30% rate or lower rate specified by an applicable income tax treaty) may apply to any “effectively connected earnings and profits” (subject to adjustments)), or (ii) such Non-U.S. Holder is an individual who has been present in the United States for 183 days or more in the taxable year of disposition, and certain other conditions are met, in which case, such holder will generally be subject to a 30% tax on the net gain derived from the disposition, which may be offset by certain U.S. source capital losses realized during the same taxable year, if any.

Additional tax on net investment income.    It is unclear whether the newly enacted Medicare tax on unearned income (discussed in more detail above under “—U.S. Holders—Additional tax on net investment income”) applies to Non-U.S. Holders that are estates or trusts and that have one or more U.S. beneficiaries. Prospective Non-U.S. Holders that are estates or trusts with one or more U.S. beneficiaries should consult their own tax advisors with respect to the application of the newly enacted Medicare tax to their purchase, ownership and disposition of notes.

Information reporting and backup withholding

U.S. Holders.    Payments of interest on, and the proceeds of the sale, exchange, redemption or other taxable disposition of, a note are generally subject to information reporting unless the U.S. Holder is an exempt recipient and appropriately establishes that exemption. Such payments may also be subject to U.S. federal backup withholding tax at the applicable rate if the U.S. Holder fails to supply a properly completed and executed IRS Form W-9 providing such U.S. Holder’s taxpayer identification number, certified under penalties of perjury, as well as certain other information or otherwise fails to establish an exemption from backup withholding. Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules will be allowed as a credit against a U.S. Holder’s U.S. federal income tax liability, if any, and may entitle such holder to a refund, provided the required information is timely furnished to the IRS.

Non-U.S. Holders.    We (or our paying agent) generally must report annually to the IRS and to each Non-U.S. Holder the amount of interest paid on the notes and the amount of tax, if any, withheld with respect to such payments. Backup withholding will not generally apply to interest payments made by us (including our paying agents) to a Non-U.S. Holder in respect of the notes if such Non-U.S. Holder furnishes us or our paying agent with appropriate documentation of such holder’s non-U.S. status or otherwise establishes an exemption.

The payment of proceeds from a Non-U.S. Holder’s sale, exchange, redemption or other taxable disposition of notes to or through the U.S. office of any broker, domestic or foreign, will be subject to information reporting and possibly backup withholding unless such holder provides a properly completed and executed IRS Form W-8BEN (or other applicable IRS Form W-8) certifying as to its non-U.S. status under penalties of perjury or otherwise establishing an exemption. The payment of proceeds from a Non-U.S. Holder’s disposition of a note to or through a non-U.S. office of either a U.S. broker or a non-U.S. broker with certain specified United States connections will be subject to information reporting (but generally not backup withholding) unless such broker has documentary evidence in its files that such Non- U.S. Holder is not a

S-142

U.S. person. Neither information reporting nor backup withholding will apply to a payment of proceeds from a Non-U.S. Holder’s disposition of notes by or through a non-U.S. office of a non-U.S. broker without certain specified United States connections.

Copies of any information returns filed with the IRS may be made available by the IRS, under the provisions of a specific treaty or agreement, to the tax authorities of the country in which the Non-U.S. Holder resides.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules from a payment to a Non-U.S. Holder will be allowed as a credit against the Non-U.S. Holder’s U.S. federal income tax liability, if any, and may entitle such holder to a refund, provided the required information is timely furnished to the IRS.

S-143

Underwriting

Subject to the terms and conditions in the underwriting agreement between us and the underwriters, we have agreed to sell to each underwriter, and each underwriter has agreed to purchase from us, the principal amount of notes set forth opposite its name in the table below:

Underwriters	Principal amount of 2022 notes	Principal amount of 2024 notes
J.P. Morgan Securities LLC	$	$
Credit Suisse Securities (USA) LLC
Deutsche Bank Securities Inc.
Citigroup Global Markets Inc.
Goldman, Sachs & Co.
RBC Capital Markets, LLC
RBS Securities Inc.
	$	$

The obligations of the underwriters under the underwriting agreement, including their agreement to purchase notes from us, are several and not joint. The underwriting agreement provides that the underwriters will purchase all the notes if any of them are purchased. The underwriters initially propose to offer the notes to the public at the public offering price that appears on the cover page of this prospectus supplement. The underwriters may offer the notes to selected dealers at the public offering price minus a concession of up to     % of the principal amount of the notes. In addition, the underwriters may allow, and those selected dealers may reallow, a concession of up to     % of the principal amount of the notes to certain other dealers. After the initial offering, the underwriters may change the public offering price and any other selling terms. The underwriters may offer and sell notes through certain of their affiliates. The underwriting agreement also provides that if an underwriter defaults, the purchase commitments of non-defaulting underwriters may also be increased or the offering may be terminated.

The expenses of the offering, not including the underwriting discount, are estimated to be approximately $        , and are payable by us. In the underwriting agreement, we have agreed that:

• We will not offer or sell any of our debt securities (other than the notes) for a period of 30 days after the date of this prospectus supplement without the prior consent of J.P. Morgan Securities LLC.

• We will indemnify the several underwriters against certain liabilities, including liabilities under the Securities Act, or contribute to payments that the underwriters may be required to make in respect of those liabilities.

The notes are a new issue of securities for which there is no established trading market. We do not intend to apply for the notes to be listed on any securities exchange or to arrange for the notes to be quoted on any quotation system. The underwriters have advised us that certain underwriters intend to make a market in the notes. However, they are not obligated to do so and they may discontinue any market making at any time in their sole discretion. Therefore, we cannot assure you that a liquid trading market will develop for the notes, that you will be able to sell your notes at a particular time or that the prices that you receive when you sell will be favorable.

S-144

You should be aware that the laws and practices of certain countries require investors to pay stamp taxes and other charges in connection with purchases of securities.

In relation to each Member State of the European Economic Area which has implemented the Prospectus Directive (each, a “Relevant Member State”), each underwriter has represented and agreed that with effect from and including the date on which the Prospectus Directive is implemented in that Relevant Member State (the “Relevant Implementation Date”) it has not made and will not make an offer of the notes to the public in that Relevant Member State prior to the publication of a prospectus in relation to the notes which has been approved by the competent authority in that Relevant Member State or, where appropriate, approved in another Relevant Member State and notified to the competent authority in that Relevant Member State, all in accordance with the Prospectus Directive and the 2010 PD Amending Directive to the extent implemented, except that it may, with effect from and including the Relevant Implementation Date, make an offer of notes to the public in that Relevant Member State at any time:

• to any legal entity which is a qualified investor as defined in the Prospectus Directive or the 2010 PD Amending Directive if the relevant provision has been implemented;

• to fewer than (i) 100 natural or legal persons per Relevant Member State (other than qualified investors as defined in the Prospectus Directive or the 2010 PD Amending Directive if the relevant provision has been implemented) or (ii) if the Relevant Member State has implemented the relevant provision of the 2010 PD Amending Directive, 150 natural or legal persons per Relevant Member State (other than qualified investors as defined in the Prospectus Directive or the 2010 PD Amending Directive if the relevant provision has been implemented), subject to obtaining the prior consent of the relevant dealer or dealers nominated by the company for any such offer; or

• in any other circumstances falling within Article 3(2) of the Prospectus Directive or Article 3(2) of the 2010 PD Amending Directive to the extent implemented.

For the purposes of this provision, the expression an “offer of the notes to the public,” in relation to any notes in any Relevant Member State, means the communication in any form and by any means of sufficient information on the terms of the offer and the notes to be offered so as to enable an investor to decide to purchase or subscribe for the notes, as the same may be varied in that Relevant Member State by any measure implementing the Prospectus Directive in that Relevant Member State, the expression “Prospectus Directive” means Directive 2003/71/EC, and includes any relevant implementing measure in that Relevant Member State, and the expression “2010 PD Amending Directive” means Directive 2010/73/EC.

Each underwriter has represented and agreed that:

• it has only communicated or caused to be communicated and will only communicate or cause to be communicated an invitation or inducement to engage in investment activity (within the meaning of Section 21 of the Financial Services and Markets Act 2000) received by it in connection with the issue or sale of the notes in circumstances in which Section 21(1) of the Financial Services and Markets Act 2000 does not apply to us; and

• it has complied and will comply with all applicable provisions of the Financial Services and Markets Act 2000 with respect to anything done by it in relation to the notes in, from or otherwise involving the United Kingdom.

S-145

In connection with the offering of the notes, the underwriters may engage in overallotment, stabilizing transactions and syndicate covering transactions. Overallotment involves sales in excess of the offering size, which creates a short position for the underwriters. Stabilizing transactions involve bids to purchase the notes in the open market for the purpose of pegging, fixing or maintaining the price of the notes. Syndicate covering transactions involve purchases of the notes in the open market after the distribution has been completed in order to cover short positions. Stabilizing transactions and syndicate covering transactions may cause the price of the notes to be higher than it would otherwise be in the absence of those transactions. If the underwriters engage in stabilizing or syndicate covering transactions, they may discontinue them at any time.

The underwriters and their respective affiliates are full service financial institutions engaged in various activities, which may include securities trading, commercial and investment banking, financial advisory, investment management, investment research, principal investment, hedging, financing and brokerage activities. From time to time, the underwriters and their respective affiliates have directly and indirectly provided investment banking, commercial banking and financial advisory services to us for which they have received customary compensation and expense reimbursement. The underwriters and their affiliates may in the future provide similar services.

In the ordinary course of their various business activities, the underwriters and their respective affiliates may make or hold, a broad array of investments, including serving as counterparties to certain derivative and hedging arrangements, and may actively trade, debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers and may have in the past and at any time in the future hold long and short positions in such securities and instruments. Such investment and securities activities may have involved, and in the future may involve, our securities and instruments. The underwriters and their respective affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or instruments and may at any time hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

S-146

ABOUT US

Our Company

T-Mobile is a national provider of mobile communications services capable of reaching over 280 million Americans. Our objective is to be the simpler choice for a better mobile experience. Our intent is to bring this proposition to life across all our brands, including T-Mobile, MetroPCS, and GoSmart, and across our major customer base of retail, wholesale and business (B2B) consumers.

We generate revenue by offering affordable postpaid and prepaid wireless voice, messaging and data services, as well as mobile broadband and wholesale wireless services. We provided service to approximately 45 million customers through our nationwide network as of September 30, 2013. We also generate revenues by offering a wide selection of wireless handsets and accessories, including smartphones, wireless-enabled computers such as notebooks and tablets, and data cards which are manufactured by various suppliers. Our most significant expenses are related to acquiring and retaining customers, maintaining and expanding our network, and compensating employees.

Transaction

On April 30, 2013, the transactions contemplated by the Business Combination Agreement (the “Business Combination Agreement”), dated October 3, 2012, by and among Deutsche Telekom AG (“Deutsche Telekom”), T-Mobile Global Zwischenholding GmbH, a direct wholly-owned subsidiary of Deutsche Telekom (“Global”), T-Mobile Global Holding GmbH, a direct wholly-owned subsidiary of Global (“Holding”), T-Mobile USA, Inc., formerly a direct wholly-owned subsidiary of Holding, and T-Mobile US, Inc. (formerly known as MetroPCS Communications, Inc.) were consummated. Pursuant to the terms of the Business Combination Agreement, among other things:

• our certificate of incorporation was amended and restated to, among other things, effect a recapitalization that included a reverse stock split pursuant to which each share of our common stock outstanding as of the effective time of the reverse stock split now represents one-half of a share of our common stock;

• as part of the recapitalization, we made a payment in cash, which we refer to as the cash payment, in the aggregate amount of $1.5 billion, without interest (or approximately $4.05 per share pre-reverse stock split of common stock), to the record holders of our common stock immediately following the effective time of the reverse stock split;

• immediately following the cash payment, we acquired from Deutsche Telekom’s subsidiary, Holding, all of the shares of capital stock of T-Mobile USA in consideration for newly-issued shares of common stock representing approximately 74% of our outstanding common stock on a fully-diluted basis;

• our name was changed from “MetroPCS Communications, Inc.” to “T-Mobile US, Inc.”; and

• we and Deutsche Telekom entered into a Stockholder’s Agreement, which we refer to as the Stockholder’s Agreement, which sets forth certain governance, registration and other rights of Deutsche Telekom. See “Description of Capital Stock.”

In addition, following the closing of the transactions summarized above, MetroPCS, Inc., a direct wholly-owned subsidiary of ours, merged with and into its direct wholly-owned subsidiary MetroPCS Wireless, Inc., with MetroPCS Wireless, Inc. continuing as the surviving entity and, immediately thereafter, MetroPCS Wireless, Inc. merged with and into T-Mobile USA, with T-Mobile USA continuing as the surviving entity and our wholly-owned subsidiary. We refer to the transactions contemplated by the Business Combination Agreement collectively as the Business Combination Transaction.

In connection with the Business Combination Transaction, T-Mobile USA issued notes in an aggregate principal amount of $11.2 billion to Deutsche Telekom to refinance certain intercompany indebtedness between

2

T-Mobile USA and its subsidiaries and Deutsche Telekom and its subsidiaries (other than T-Mobile USA and its subsidiaries). In addition, Deutsche Telekom made available for the benefit of T-Mobile USA a revolving unsecured credit facility with a maximum principal amount of $500.0 million to be used for working capital and other general corporate purposes.

Although T-Mobile US, Inc. (formerly known as MetroPCS Communications, Inc.) was the legal acquirer of T-Mobile USA, Inc. in the Business Combination Transaction, for accounting purposes, the Business Combination Transaction is treated as a “reverse acquisition,” and T-Mobile USA is treated as the accounting acquirer. As a result of reverse acquisition accounting, T-Mobile USA’s historical financial statements have become our financial statements for financial reporting purposes after the consummation of the Business Combination Transaction.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

Certain statements in this prospectus, the documents incorporated by reference or our other public statements include “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 our possible or assumed future results of operations, are forward-looking statements. These forward-looking statements are generally identified by the words “anticipates,” “believes,” “estimates,” “expects,” or similar expressions.

Forward-looking statements are based on current expectations and assumptions which are subject to risks and uncertainties which may cause actual results to differ materially from the forward-looking statements. The following important factors, among others, along with the factors identified under “Risk Factors” and the risk factors incorporated by reference herein, could affect future results and could cause those results to differ materially from those expressed in the forward-looking statements:

• adverse conditions in the U.S. and international economies or disruptions to the credit and financial markets;

• competition in the wireless services market;

• the ability to complete and realize expected synergies and other benefits of acquisitions;

• the inability to implement our business strategies or ability to fund our wireless operations, including payment for additional spectrum, network upgrades, and technological advancements;

• the ability to renew our spectrum licenses on attractive terms or acquire new spectrum licenses;

• the ability to manage growth in wireless data services including network quality and acquisition of adequate spectrum licenses at reasonable costs and terms;

• material changes in available technology;

• the timing, scope and financial impact of our deployment of 4G Long-Term Evolution (LTE) technology;

• the impact on our networks and business from major technology equipment failures;

• breaches of network or information technology security, natural disasters or terrorist attacks or existing or future litigation and any resulting financial impact not covered by insurance;

• any changes in the regulatory environments in which we operate, including any increase in restrictions on the ability to operate our networks;

• any disruption of our key suppliers’ provisioning of products or services;

• material adverse changes in labor matters, including labor negotiations or additional organizing activity, and any resulting financial and/or operational impact;

• changes in accounting assumptions that regulatory agencies, including the SEC, may require or that result from changes in the accounting rules or their application, which could result in an impact on earnings; and

• changes in tax laws, regulations and existing standards and the resolution of disputes with any taxing jurisdictions.

Additional information concerning these and other risk factors is contained in our Quarterly Report on Form 10-Q for the quarterly period ended June 30, 2013 and in the other documents incorporated herein by reference.

Forward-looking statements in this prospectus or the documents incorporated by reference speak only as of the date of this prospectus or the applicable document referred to or incorporated by reference (or such earlier date as may be specified in the applicable document), as applicable, are based on assumptions and expectations

6

as of such dates, and involve risks, uncertainties and assumptions, many of which are beyond our ability to control or predict, including the factors above. You should not place undue reliance on these forward-looking statements. We do not intend to, and do not undertake an obligation to, update these forward-looking statements in the future to reflect future events or circumstances, except as required by applicable securities laws and regulations. For more information, see the section entitled “Where You Can Find More Information.” The results presented for any period may not be reflective of results for any subsequent period.

You should carefully read and consider the cautionary statements contained or referred to in this section in connection with any subsequent written or oral forward-looking statements that may be issued by us or persons acting on our behalf, and all future written and oral forward-looking statements attributable to us are expressly qualified in their entirety by the foregoing cautionary statements.

USE OF PROCEEDS

Unless otherwise indicated in the applicable prospectus supplement, we expect to use the net proceeds from the sale of the securities by us described in this prospectus for general corporate purposes, which could include working capital, capital expenditures, the repayment or refinancing, in whole or in part, of debt, acquisition of additional spectrum, asset or business acquisitions, repurchase, redemption or retirement of securities, corporate development opportunities and future technology initiatives. Unless otherwise set forth in a prospectus supplement, we will not receive any proceeds from the sale of securities by any selling securityholders.

RATIO OF EARNINGS TO FIXED CHARGES

The following table sets forth consolidated ratio of earnings to fixed charges for each of the last five years and for the nine months ended September 30, 2013. For periods prior to the Business Combination Transaction, the ratio represents only T-Mobile USA as the accounting acquirer in the business combination.

	Year Ended December 31,												Nine Months Ended September 30, 2013
	2008		2009		2010		2011			2012
Ratio of earnings to fixed charges (1)		3.48x		2.47x		2.55x		—	(2)		—	(2)		1.16x

(1) For purposes of calculating the ratio of earnings to fixed charges, earnings available for fixed charges consists of (loss) income before income taxes and earnings from unconsolidated affiliates plus fixed charges and amortization of capitalized interest less capitalized interest and earnings from non-controlling interests. Fixed charges include interest expense including capitalized interest and the portion of operating rental expense that management believes is representative of the appropriate interest component of rental expense. The portion of total rental expense that represents the interest factor is estimated to be 33%.

(2) The ratio coverage for the years ended December 31, 2012 and 2011 was less than 1:1 in each of these periods. T-Mobile USA would have needed to generate additional earnings of $7.0 billion and $4.9 billion in the years ended December 31, 2012 and 2011, respectively, to achieve a coverage ratio of 1:1 in each of these periods.

DESCRIPTION OF CAPITAL STOCK

The following describes our common stock, preferred stock, certificate of incorporation and bylaws that are presently in effect, the Stockholder’s Agreement, and the Rights Agreement, dated as of March 29, 2007, as amended, that we have entered into with American Stock Transfer & Trust Company, LLC, as rights agent (the “Rights Plan”). This description is a summary only. We encourage you to read the complete text of such documents, which are incorporated by reference herein.

The authorized capital stock of T-Mobile US, Inc. consists of 1,000,000,000 shares of common stock, par value $0.00001 per share, and 100,000,000 shares of preferred stock, par value $0.00001 per share.

Common Stock

Holders of our common stock have the right to vote on every matter submitted to a vote of our stockholders other than any matter on which only the holders of preferred stock are entitled to vote separately as a class. There are no cumulative voting rights. Accordingly, holders of a majority of shares entitled to vote in an election of directors are able to elect all of the directors standing for election.

Subject to preferences that may be applicable to any outstanding preferred stock, the holders of common stock will share equally on a per share basis any dividends when, as and if declared by our board of directors out of funds legally available for that purpose. If we are liquidated, dissolved or wound up, the holders of our common stock will be entitled to a ratable share of any distribution to stockholders, after satisfaction of all of our liabilities and of the prior rights of any outstanding class of preferred stock. Our common stock carries no preemptive or other subscription rights to purchase shares of our common stock and is not convertible, assessable or entitled to the benefits of any sinking fund.

Redemption

Pursuant to our certificate of incorporation, if a holder of our common stock acquires additional shares of our common stock or otherwise is attributed with ownership of such shares that would cause us to violate FCC rules, we may, at the option of the board of directors, redeem from the holder or holders causing the violation of the FCC’s rules shares of our common stock sufficient to eliminate the violation.

The redemption price will be a price mutually determined by us and our stockholders, but if no agreement can be reached, the redemption price will be either:

• 75% of the fair market value of our common stock being redeemed, if the holder caused the FCC violation; or

• 100% of the fair market value of our common stock being redeemed, if the FCC violation was not caused by the holder.

The foregoing redemption rights do not apply to any shares of our common stock or preferred stock beneficially owned by Deutsche Telekom or any of its subsidiaries. If any waivers or approvals are required from the FCC in order for Deutsche Telekom or any of its subsidiaries to acquire or hold any shares of our common stock or preferred stock, Deutsche Telekom and any of its subsidiaries shall cooperate to secure such waivers or approvals and abide by any conditions related to such waivers or approvals.

Preferred Stock

Subject to the provisions of our certificate of incorporation and the limitations prescribed by law, our certificate of incorporation authorizes the board of directors to issue up to 100,000,000 shares of preferred stock in one or more series and to fix the rights, preferences, privileges and restrictions of the preferred stock, including dividend rights, dividend rates, conversion rates, voting rights, terms of redemption, redemption prices,

12

liquidation preferences and the number of shares constituting any series or the designation of the series, which may be superior to those of our common stock, without further vote or action by the stockholders. We currently have no shares of preferred stock outstanding.

One of the effects of undesignated preferred stock may be to enable the board of directors to render more difficult or to discourage an attempt to obtain control of us by means of a tender offer, proxy contest, merger or otherwise, and as a result, protect the continuity of our management. The issuance of shares of preferred stock under the board of directors’ authority described above may adversely affect the rights of the holders of our common stock. For example, preferred stock issued by us may rank prior to our common stock as to dividend rights, liquidation preference or both, may have full or limited voting rights and may be convertible into shares of our common stock. Accordingly, the issuance of shares of preferred stock may discourage bids for our common stock or may otherwise adversely affect the market price of our common stock.

For purposes of the Rights Plan described below, the board of directors has designated 1,000,000 shares of preferred stock to constitute the series A junior participating preferred stock, par value $0.00001 per share, or Series A Preferred Stock. For a summary description of the Rights Plan, please read “—Rights Plan” below.

Rights Plan

We adopted a Rights Plan in March 2007, which we amended in October 2012. Under the Rights Plan, each share of our common stock includes one right to purchase one one-thousandth of a share of Series A Preferred Stock. The rights will separate from our common stock and become exercisable (1) ten calendar days after public announcement that a person or group of affiliated or associated persons has acquired, or obtained the right to acquire, beneficial ownership of 15% of our outstanding common stock or (2) ten business days following the start of a tender offer or exchange offer that would result in a person’s acquiring beneficial ownership of 15% of our outstanding common stock. A 15% beneficial owner is referred to as an “acquiring person” under the Rights Plan.

The board of directors can elect to delay the separation of the rights from our common stock beyond the ten-day periods referred to above. The Rights Plan also confers on the board of directors the discretion to increase or decrease the level of ownership that causes a person to become an acquiring person. Until the rights are separately distributed, the rights will not be evidenced by separate certificates and will be transferred with and only with our common stock certificates.

After the rights are separately distributed, each right will entitle the holder to purchase from us one one-thousandth of a share of Series A Preferred Stock for a purchase price of $66.67. The rights will expire at the close of business on March 27, 2017, unless we redeem or exchange them earlier as described below.

If a person becomes an acquiring person, the rights will become rights to purchase shares of our common stock for one-half the current market price, as defined in the rights agreement, of our common stock. This occurrence is referred to as a “flip-in event” under the plan. After any flip-in event, all rights that are beneficially owned by an acquiring person, or by certain related parties, will be null and void. The board of directors will have the power to decide that a particular tender or exchange offer for all outstanding shares of our common stock is fair to and otherwise in the best interests of our stockholders. If the board of directors makes this determination, the purchase of shares under the offer will not be a flip-in event.

If, after there is an acquiring person, we are acquired in a merger or other business combination transaction or 50% or more of its assets, earning power or cash flow are sold or transferred, each holder of a right will have the right to purchase shares of the common stock of the acquiring company at a price of one-half the current market price of that stock. This occurrence is referred to as a “flip-over event” under the plan. An acquiring person will not be entitled to exercise its rights, which will have become void.

13

Until ten days after the announcement that a person has become an acquiring person, the board of directors may decide to redeem the rights at a price of $0.001 per right, payable in cash, shares of our common stock or other consideration. The rights will not be exercisable after a flip-in event until the rights are no longer redeemable.

At any time after a flip-in event and prior to either a person’s becoming the beneficial owner of 50% or more of the shares of our common stock or a flip-over event, the board of directors may decide to exchange the rights for shares of our common stock on a one-for-one basis. Rights owned by an acquiring person that will have become void, will not be exchanged.

Other than provisions relating to the redemption price of the rights, the Rights Plan may be amended by the board of directors at any time that the rights are redeemable. Thereafter, the provisions of the Rights Plan other than the redemption price may be amended by the board of directors to cure any ambiguity, defect or inconsistency, to make changes that do not materially adversely affect the interests of holders of rights (excluding the interests of any acquiring person), or to shorten or lengthen any time period under the Rights Plan. No amendment to lengthen the time period for redemption may be made if the rights are not redeemable at that time.

The rights have certain anti-takeover effects. The rights will cause substantial dilution to any person or group that attempts to acquire us without the approval of the board of directors. As a result, the overall effect of the rights may be to render more difficult or discourage any attempt to acquire us even if the acquisition may be favorable to the interests of our stockholders. Because the board of directors can redeem the rights or approve a tender or exchange offer, the rights should not interfere with a merger or other business combination approved by the board of directors.

Anti-takeover Effects of Delaware Law and Our Certificate of Incorporation and Bylaws

Delaware law

We are a Delaware corporation and are subject to Delaware law, which generally prohibits a publicly held Delaware corporation from engaging in a “business combination” with an “interested stockholder” for a period of three years after the time that the person became an interested stockholder, unless:

• before such time the board of directors of the corporation approved either the business combination or the transaction in which the person became an interested stockholder;

• upon completion of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding shares owned by persons who are directors and also officers of the corporation and by certain employee stock plans; or

• at or after such time the business combination is approved by the board of directors of the corporation and authorized at an annual or special meeting of stockholders, and not by written consent, by the affirmative vote of at least 66 ²⁄₃% of the outstanding voting stock of the corporation that is not owned by the interested stockholder.

A “business combination” generally includes mergers, asset sales and similar transactions between the corporation and the interested stockholder, and other transactions resulting in a financial benefit to the stockholder. An “interested stockholder” is a person:

• who, together with affiliates and associates, owns 15% or more of the corporation’s outstanding voting stock; or

• who is an affiliate or associate of the corporation and, together with his or her affiliates and associates, has owned 15% or more of the corporation’s outstanding voting stock within three years.

The provisions of Delaware law described above along with our certificate of incorporation would make more difficult or discourage a proxy contest or acquisition of control by a holder of a substantial block of our common stock or the removal of the incumbent board of directors. Such provisions could also have the effect of discouraging an outsider from making a tender offer or otherwise attempting to obtain control of our Company, even though such an attempt might be beneficial to us and our stockholders.

Our Certificate of Incorporation and Bylaws

The following provisions of our certificate of incorporation and bylaws could be deemed to have an anti-takeover effect and could delay, defer or prevent a takeover attempt that a stockholder might consider to be in the stockholders’ best interests.

• Advance notice of director nominations and matters to be acted upon at meetings. Our bylaws contain advance notice requirements for nominations for directors to our board of directors and for proposing matters that can be acted upon by stockholders at stockholder meetings.

• Amendment to bylaws. Our certificate of incorporation provides that our bylaws may be amended upon the affirmative vote of the holders of shares having a majority of our voting power. Our certificate of incorporation also provides that our board of directors is authorized to make, alter or repeal our bylaws without further stockholder approval.

• Special meeting of stockholders. Our certificate of incorporation provides that a special meeting of our stockholders (i) may be called by the chairman of the board or our chief executive officer and (ii) must be called by our secretary at the request of (a) a majority of our board of directors or (b) as long as Deutsche Telekom beneficially owns 25% or more of the outstanding shares of our common stock, the holders of not less than 33- ¹⁄₃% of the voting power of all of the outstanding voting stock of our Company entitled to vote generally for the election of directors.

• Board representation. Our certificate of incorporation (as well as the Stockholder’s Agreement described below) provides that Deutsche Telekom generally has the right to designate a number of Deutsche Telekom designees to our board of directors and any committees thereof equal to the percentage of our common stock beneficially owned by Deutsche Telekom multiplied by the number of directors on our board of directors (or the number of members of any committee thereof), in each case, rounded to the nearest whole number. These rights will remain in effect as long as Deutsche Telekom beneficially owns 10% or more of the outstanding shares of our common stock. Our certificate of incorporation provides that all of the directors of our board of directors are of one class and are elected annually.

• Special approval rights. Our certificate of incorporation provides Deutsche Telekom with the same approval rights as are set forth in the Stockholder’s Agreement with respect to our ability to take certain actions (including, without limitation, changing the size of our board of directors or dispositions in excess of $1,000,000,000, or hiring or terminating without cause our chief executive officer) without Deutsche Telekom’s prior written consent as long as Deutsche Telekom beneficially owns 30% or more of the outstanding shares of our common stock.

• Authorized but unissued shares. The authorized but unissued shares of our common stock and preferred stock are available for future issuance without stockholder approval. These additional shares may be used for a variety of corporate purposes, such as for additional public offerings, acquisitions and employee benefit plans. The existence of authorized but unissued and unreserved common stock and preferred stock could render more difficult or discourage an attempt to obtain control of our Company by means of a proxy contest, tender offer, merger or otherwise.

• Cumulative voting. Our certificate of incorporation does not permit cumulative voting in the election of directors. Instead, any election of directors will be decided by a plurality of the votes cast (in person or by proxy) by holders of our common stock.

15

Stockholder’s Agreement

Pursuant to the Stockholder’s Agreement, Deutsche Telekom has the right to designate a number of individuals to be nominees for election to our board of directors equal to the percentage of our common stock beneficially owned by Deutsche Telekom multiplied by the number of directors on our board rounded to the nearest whole number. In addition, we have agreed to include as members of each committee of our board of directors the number of Deutsche Telekom director designees equal to the percentage of common stock beneficially owned by Deutsche Telekom multiplied by the number of members of such committee, except to the extent that such membership would violate applicable law or stock exchange rules; provided that no committee may consist solely of directors designated by Deutsche Telekom. These rights will remain in effect as long as Deutsche Telekom beneficially owns 10% or more of the outstanding shares of our common stock. We and Deutsche Telekom have also each agreed to use our reasonable best efforts to cause at least three members of the board of directors to be considered “independent” under the rules of the SEC and under applicable listing standards.

In addition, pursuant to the Stockholder’s Agreement, as long as Deutsche Telekom beneficially owns 30% or more of the outstanding shares of our common stock, we will not take certain actions without Deutsche Telekom’s prior written consent, including (a) incurring indebtedness above certain levels based on a specified debt to cash flow ratio, (b) taking any action that would cause a default under any instrument evidencing indebtedness of Deutsche Telekom or its affiliates, (c) acquiring or disposing of assets or entering into mergers or similar acquisitions in excess of $1,000,000,000, (d) changing the size of our board of directors, (e) issuing equity of 10% or more of the then outstanding number of shares of our common stock or to redeem debt held by Deutsche Telekom, (f) except as required by our organizational documents, repurchasing or redeeming equity securities or making any extraordinary or in-kind dividend other than on a pro rata basis or (g) making certain changes involving our chief executive officer. In addition, we have agreed not to amend our certificate of incorporation and bylaws in any manner that could adversely affect Deutsche Telekom’s rights under the Stockholder’s Agreement as long Deutsche Telekom beneficially owns 5% or more of the outstanding shares of our common stock.

During the term of the Stockholder’s Agreement, Deutsche Telekom is not permitted to, and is required to cause the Deutsche Telekom designees then serving as directors on our board not to, support, enter into or vote in favor of any transaction between, or involving both (A) the Company and (B) Deutsche Telekom or an affiliate of Deutsche Telekom, unless such transaction is approved by a majority of the directors on the combined company’s board, which majority includes a majority of the disinterested directors.

Pursuant to the Stockholder’s Agreement, Deutsche Telekom and its affiliates are prohibited from acquiring more than 80.1% of the outstanding shares of our common stock unless it makes an offer to acquire all of the then remaining outstanding shares of common stock at the same price and on the same terms and conditions as the proposed acquisition from all other stockholders of the Company, which is approved or accepted by disinterested directors or stockholders. Deutsche Telekom is also prohibited from publicly transferring any shares of our common stock during the 18-month period after the closing of the transactions contemplated by the Business Combination Agreement, subject to certain exceptions. Deutsche Telekom is also prohibited from transferring any shares of common stock in any other transaction that would result in the transferee owning more than 30% of the outstanding shares of common stock unless such transferee offers to acquire all of the then outstanding shares of common stock at the same price and on the same terms and conditions as the proposed transfer. The Stockholder’s Agreement also restricts Deutsche Telekom’s ability to compete with us in the United States, Puerto Rico and the territories and protectorates of the United States during the period beginning on April 30, 2013 and ending on the date that is two years after the date on which Deutsche Telekom beneficially owns less than 10% of the outstanding shares of our common stock.

Subject to specified limitations, Deutsche Telekom has the right to request that we file, from time to time, a registration statement or prospectus supplement to a registration statement for the resale of shares of our common stock and debt securities beneficially owned by Deutsche Telekom and acquired in connection with the Business

16

Combination Transaction or in the future after the expiration of the lock-up described. In addition, Deutsche Telekom has piggyback registration rights with respect to any offering initiated by the Company. Any transferee of Deutsche Telekom who acquires at least 5% of either the registrable equity securities or the registrable debt securities pursuant to a transaction that is not registered under the Securities Act will be entitled to enjoy the same registration rights as Deutsche Telekom as long as the registrable securities held by such transferee may not be sold or disposed of pursuant to Rule 144 under the Securities Act without volume limitations.

Limitations on Liability and Indemnification of Officers and Directors

Our certificate of incorporation and bylaws:

• eliminate the personal liability of directors for monetary damages resulting from breaches of fiduciary duty to the extent permitted by Delaware law, except (i) for any breach of a director’s duty of loyalty to the Company or its stockholders, (ii) for acts or omissions not in good faith or which involved intentional misconduct or a knowing violation of law, or (iii) for any transaction from which the director derived an improper personal benefit; and

• indemnify directors and officers to the fullest extent permitted by Delaware law, including in circumstances in which indemnification is otherwise discretionary.

We believe that these provisions are necessary to attract and retain qualified directors and officers. We have also entered into separate indemnification agreements with each of our directors and officers under which we have agreed to indemnify, and to advance expenses to, each director and officer to the fullest extent permitted by applicable law with respect to liabilities they may incur in their capacities as directors and officers.

Director Removal

Our certificate of incorporation provides that, subject to certain rights of the holders of any preferred stock, any director may be removed from office at any time, with or without cause, by the affirmative vote of the holders of at least a majority of the voting power of all of the outstanding shares of our capital stock entitled to elect such director, voting separately as a class, at a duly organized meeting of stockholders or by written consent. However, no director designated by Deutsche Telekom may be removed without the prior written consent of Deutsche Telekom.

Stockholder Action by Written Consent

Our certificate of incorporation provides that, as long as Deutsche Telekom beneficially owns 25% or more of the outstanding shares of our common stock, any action required or permitted to be taken at any annual or special meeting of our stockholders may be taken without a meeting, without prior notice and without a vote, if a consent or consents in writing setting forth the action so taken is signed by the holders of outstanding stock having not less than the minimum number of votes that would be necessary to authorize or take such action at a meeting at which all shares entitled to vote thereon were present and voted.

Governing Law; Forum for Adjudication of Disputes

Our certificate of incorporation provides that our certificate of incorporation and the internal affairs of our Company shall be governed by and interpreted under the laws of the State of Delaware. In addition, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware shall be the sole and exclusive forum for (i) any derivative action brought on behalf of our Company, (ii) any action asserting a claim of breach of a fiduciary duty owed by any director, officer or other employee of our Company to us or our stockholders, (iii) any action asserting a claim arising pursuant to any provision of the Delaware General Corporation Law (“DGCL”), our certificate of incorporation or bylaws, or (iv) any other action asserting a claim arising under, in connection with, and governed by the internal affairs doctrine.

17

Corporate Opportunities

Our certificate of incorporation provides, as permitted by the DGCL, that our non-employee directors have no obligation to offer us a corporate opportunity to participate in business opportunities presented to them or their respective affiliates even if the opportunity is one that we might reasonably have pursued, unless such corporate opportunity is offered to such director in his or her capacity as a director of our Company. Stockholders will be deemed to have notice of and consented to this provision of our certificate of incorporation.

Listing of Common Stock

Our common stock is listed on the New York Stock Exchange under the symbol “TMUS.”

Transfer Agent and Registrar

Our transfer agent and registrar is American Stock Transfer & Trust Company, LLC.

SELLING SECURITYHOLDERS

Selling securityholders may from time to time offer and sell our securities pursuant to this prospectus and any applicable prospectus supplement. Selling securityholders are persons or entities that, directly or indirectly, have acquired or from time to time acquire, our securities. Such selling securityholders may be parties to registration rights agreements with us, or we otherwise may have agreed or agree to register their securities for resale.

The applicable prospectus supplement will set forth the name of each of the selling securityholders and the number of securities beneficially owned by such selling securityholders that are covered by such prospectus supplement.

19

PLAN OF DISTRIBUTION

We or selling securityholders may sell the securities being offered hereby:

• directly to purchasers;

• through agents;

• through dealers;

• through underwriters;

• through a combination of any of the above methods of sale; or

• through any other methods described in a prospectus supplement.

We will identify the specific plan of distribution, including any direct purchasers, agents, dealers, underwriters and, if applicable, their compensation, the purchase price, the net proceeds to us, the public offering price, and any discounts or concessions allowed or reallowed or paid to dealers, in a prospectus supplement.

The distribution of securities may be effected, from time to time, in one or more transactions, including block transactions and transactions on the New York Stock Exchange or any other organized market where the securities may be traded. The securities may be sold at a fixed price or prices, which may be changed, or at market prices prevailing at the time of sale, at prices relating to the prevailing market prices or at negotiated prices. The consideration may be cash or another form negotiated by the parties. Agents, underwriters or broker-dealers may be paid compensation for offering and selling the securities. That compensation may be in the form of discounts, concessions or commissions to be received from us or from the purchasers of the securities.

Offers to purchase the securities may be solicited directly by us or any selling securityholder or by agents designated by us or any selling securityholder from time to time. We will, in the prospectus supplement relating to an offering, name any agent that could be viewed as an underwriter under the Securities Act and describe any commissions we or any selling securityholder must pay. Any such agent will be acting on a best efforts basis for the period of its appointment or, if indicated in the applicable prospectus supplement, on a firm commitment basis.

If a dealer is utilized in the sale of the securities in respect of which this prospectus is delivered, we and any selling securityholder will sell the securities to the dealer, as principal. The dealer, which may be deemed to be an underwriter as that term is defined in the Securities Act, may then resell the securities to the public at varying prices to be determined by the dealer at the time of resale. Dealer trading may take place in certain of the securities, including securities not listed on any securities exchange.

If an underwriter or underwriters are utilized in the sale, we and any selling securityholder will execute an underwriting agreement with the underwriters at the time of sale to them and the names of the underwriters will be set forth in the applicable prospectus supplement, which will be used by the underwriters to make resales of the securities in respect of which this prospectus is delivered to the public. The obligations of underwriters to purchase securities will be subject to certain conditions precedent and the underwriters will be obligated to purchase all of the securities of a series if any are purchased.

We or a selling securityholder may directly solicit offers to purchase the securities and we or a selling securityholder may make sales of securities directly to institutional investors or others. These persons may be deemed to be underwriters within the meaning of the Securities Act with respect to any resale of the securities. To the extent required, the prospectus supplement will describe the terms of any such sales, including the terms of any bidding or auction process, if used.

Underwriters, dealers, agents and other persons may be entitled, under agreements that may be entered into with us, to indemnification against certain civil liabilities, including liabilities under the Securities Act, or to

20

contribution with respect to payments that they may be required to make in respect thereof. Underwriters, dealers and agents may engage in transactions with, or perform services for, us in the ordinary course of business.

Any person participating in the distribution of common stock registered under the registration statement that includes this prospectus will be subject to applicable provisions of the Exchange Act, and the applicable SEC rules and regulations, including, among others, Regulation M, which may limit the timing of purchases and sales of our common stock by any such person. Furthermore, Regulation M may restrict the ability of any person engaged in the distribution of our common stock to engage in market-making activities with respect to our common stock. These restrictions may affect the marketability of our common stock and the ability of any person or entity to engage in market-making activities with respect to our common stock.

In order to facilitate the offering of the securities, any underwriters may engage in transactions that stabilize, maintain or otherwise affect the price of the securities or any other securities the prices of which may be used to determine payments on such securities. Specifically, any underwriters may overallot in connection with the offering, creating a short position for their own accounts. In addition, to cover overallotments or to stabilize the price of the securities or of any such other securities, the underwriters may bid for, and purchase, the securities or any such other securities in the open market. Finally, in any offering of the securities through a syndicate of underwriters, the underwriting syndicate may reclaim selling concessions allowed to an underwriter or a dealer for distributing the securities in the offering if the syndicate repurchases previously distributed securities in transactions to cover syndicate short positions, in stabilization transactions or otherwise. Any of these activities may stabilize or maintain the market price of the securities above independent market levels. Any such underwriters are not required to engage in these activities and may end any of these activities at any time.
