Our Company

As America’s supercharged Un-carrier, we have disrupted the wireless communications services industry by actively engaging with and listening to our customers and focusing on eliminating their pain points. This includes providing added value and what we believe is an exceptional experience while implementing signature Un-carrier initiatives that have changed the wireless industry. We ended annual service contracts, overages, unpredictable international roaming fees and data buckets, among other things. We are inspired by a relentless focus on customer experience, consistently delivering award-winning customer experience with our “Total Experience” approach, which drives our customer satisfaction levels while enabling operational efficiencies.

With what we believe is America’s largest, fastest, most awarded and most advanced 5G network, the Un-carrier strives to offer customers unrivaled coverage and capacity where they live, work and travel. We believe our network is the foundation of our success and powers everything we do. Our “layer cake” of spectrum provides an unmatched 5G and overall network experience to our customers, which consists of our foundational layer of low-band, our mid-band and our millimeter-wave spectrum licenses. This multilayer portfolio of spectrum broadens and deepens our nationwide 5G network, enabling accelerated innovation and increased competition in the U.S. wireless and broadband industries.

We continue to expand the footprint and improve the quality of our network, enabling us to provide what we believe are outstanding wireless experiences for customers who should not have to compromise on quality and value. Our network allows us to deliver new, innovative products and services, such as our High Speed Internet fixed wireless product, with the same customer experience focus and industry-disrupting mindset that we have adopted in our attempt to redefine the wireless communications services industry in the United States in the customers’ favor.

As of June 30, 2024, we provide wireless communications services to 125.9 million postpaid and prepaid customers and generate revenue by providing affordable wireless communications services to these customers, as well as a wide selection of wireless devices and accessories. We also provide wholesale wireless services to various partners, who then offer the services for sale to their customers. Our most significant expenses relate to operating and expanding our network, providing a full range of devices, acquiring and retaining high-quality customers and compensating employees. We provide services, devices and accessories across our flagship brands, T-Mobile and Metro by T-Mobile, through our owned and operated retail stores, as well as through our websites (www.t-mobile.com and www.metrobyt-mobile.com), T-Mobile and Metro by T-Mobile apps, customer care channels and through national retailers. In addition, we sell devices to dealers and other third-party distributors for resale through independent third-party retail outlets and a variety of third-party websites. The information on or accessible through our websites is not incorporated into or part of this prospectus supplement (except for our SEC reports expressly incorporated by reference herein).

Ranking

The Notes:

•

will be general unsecured, unsubordinated obligations of the Issuer;

•

will be senior in right of payment to any future indebtedness of the Issuer to the extent that such future indebtedness provides by its terms that it is subordinated in right of payment to the Notes;

•

will rank equal in right of payment with any of the Issuer’s existing and future indebtedness and other liabilities that are not by their terms subordinated in right of payment to the Notes, including, without limitation, the obligations under the Credit Agreement, the Existing T-Mobile Unsecured Notes, the

S-3

Existing Sprint Unsecured Notes (each as defined under “Description of Other Indebtedness and Certain Financing Transactions”) and the Tower Obligations (as defined under “Description of Notes—Certain Definitions”);

•

will be effectively subordinated to all existing and future secured indebtedness of the Issuer, to the extent of the value of the Issuer’s assets securing such indebtedness;

•

will be structurally subordinated to all of the liabilities and other obligations of the Issuer’s subsidiaries that are not obligors with respect to the Notes, including the Existing ABS Notes (as defined under “Description of Other Indebtedness and Certain Financing Transactions—Existing Asset-Backed Securities Facilities”), the Existing Sprint Spectrum-Backed Notes, factoring arrangements and tower obligations; and

See “Risk Factors—Risks Related to this Offering and the Notes—The Notes and the Guarantees will be structurally subordinated to the indebtedness and other liabilities of the Issuer’s non-guarantor subsidiaries.”

Assuming that on June 30, 2024, this offering had been completed, and converting balances in EUR into USD using end of period exchange rates, we would have had approximately $ billion of outstanding indebtedness and other obligations, excluding letter of credit obligations, including $ billion of pari passu outstanding unsecured indebtedness. Our pari passu unsecured indebtedness would consist of $ billion of Notes offered hereby, $66.7 billion of Existing T-Mobile Unsecured Notes, $7.5 billion of Existing Sprint Unsecured Notes and $3.7 billion in Tower Obligations. We also would have had $7.5 billion of revolving borrowings available on an unsecured basis under the Credit Agreement. Our effectively senior, secured indebtedness would consist of an aggregate principal amount of $1.8 billion of Existing Sprint Spectrum-Backed Notes outstanding, with up to $5.2 billion remaining available for issuance under the Sprint Spectrum Note Facility (as defined under “Description of Other Indebtedness and Certain Financing Transactions—Existing Sprint Spectrum Note Facility”), and $1.3 billion of Existing ABS Notes. The Existing Sprint Spectrum Note Entities own a pool of 2.5 GHz and 1.9 GHz spectrum which has been pledged to secure indebtedness under the Sprint Spectrum Note Facility. The Existing ABS Notes are secured by approximately $1.6 billion of gross Equipment Installment Plan (“EIP”) receivables and future collections on such receivables.

Note Guarantees

The Notes will be guaranteed (i) initially by Parent and any wholly-owned subsidiary of the Issuer that is not an Excluded Subsidiary and is an obligor of the Credit Agreement and (ii) by any future direct or

S-4

indirect subsidiary of T-Mobile US that is not a subsidiary of T-Mobile USA or any other guarantor that owns capital stock of T-Mobile USA. See “Description of Notes—Brief Description of the Notes and the Note Guarantees—The Note Guarantees.” Each Guarantee of the Notes by a guarantor:

•

will be a general unsecured, unsubordinated obligation of such guarantor;

•

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

•

will be equal in right of payment with any of that guarantor’s existing and future indebtedness and other liabilities that are not by their terms subordinated in right of payment to the Notes, including, without limitation, obligations under the Credit Agreement, the Existing T-Mobile Unsecured Notes and the Existing Sprint Unsecured Notes;

•

will be effectively subordinated to any Guarantor’s existing and future secured indebtedness to the extent of the value of the assets of such Guarantor securing such Indebtedness (as defined under “Description of Notes—Certain Definitions”); and

•

will be structurally subordinated to all of the indebtedness and other obligations of any subsidiaries of that guarantor that are not obligors with respect to the Notes.

See “Risk Factors—Risks Related to this Offering and the Notes—The Notes and the Guarantees will be unsecured and effectively subordinated to the Issuer’s and the guarantors’ existing and future secured indebtedness” and “Risk Factors—Risks Related to this Offering and the Notes—The Notes and the Guarantees will be structurally subordinated to the indebtedness and other liabilities of the Issuer’s non-guarantor subsidiaries.”

As of June 30, 2024, subsidiaries that will not provide guarantees of the Notes that were included in Parent’s consolidated financial statements as of such date had approximately $11.9 billion of total assets and approximately $5.2 billion in indebtedness and Tower Obligations outstanding.

A guarantor will be automatically and unconditionally released from its obligations in respect of the Notes of any series if, immediately following such release and any concurrent releases of other guarantees of the subsidiary guarantors, the aggregate principal amount of indebtedness for borrowed money of non-guarantor subsidiaries that are not Excluded Subsidiaries (excluding any indebtedness under any Permitted Receivables Financing (as defined under “Description of Notes—Certain Definitions”) and any indebtedness of an “Unrestricted Subsidiary” (or the equivalent thereof) under the Credit Agreement or Permitted Receivables Financing Subsidiary (as defined under “Description of Notes—

S-5

Certain Definitions”)) that would remain incurred or issued and outstanding would not exceed $2,000.0 million. See “Description of Notes—Brief Description of the Notes and the Note Guarantees—The Note Guarantees.”

Certain Covenants

The indentures governing the Notes will contain covenants that, among other things, limit the ability of the Issuer and certain of its subsidiaries to:

•

create liens or other encumbrances on Principal Property (as defined under “Description of Notes—Certain Definitions”) in respect of indebtedness for borrowed money; and

•

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

These covenants will be 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.”

As a result, a liquid market for the Notes may not be available if you wish to sell your Notes.

Trustee

The trustee for the Notes will be Deutsche Bank Trust Company Americas.

Governing Law

The Notes, the indentures governing the Notes and the Guarantees will be governed by the laws of the State of New York.

Risk Factors

You should consider carefully all of the information set forth in this prospectus supplement, the accompanying prospectus, any related free writing 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-7 of this prospectus supplement and those risk factors incorporated by reference herein.

S-6

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, as well as those discussed under the caption “Risk Factors” in Parent’s Annual Report on Form 10-K for the year ended December 31, 2023 filed on February 2, 2024 and Parent’s Quarterly Reports on Form 10-Q for the quarterly periods ended March 31, 2024 and June 30, 2024 filed on April 26, 2024 and July 31, 2024, respectively. If any of the risks described in this prospectus supplement, the accompanying prospectus or any related free writing prospectus, or the risks described in any documents incorporated by reference in this prospectus supplement, the accompanying prospectus or any related free writing 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 this Offering and the Notes

Our substantial level of indebtedness could adversely affect our business, financial condition and operating results.

We have, and we expect that we will continue to have, a substantial amount of debt.

Our ability to make payments on our debt, to repay our indebtedness when due and to fund our capital intensive business and operations and significant planned capital expenditures will depend on our ability to generate cash in the future. There can be no assurance that sufficient funds will be available to us under our borrowings or otherwise. 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 or changes in service plans or pricing by us or our competitors;

•

customers’ acceptance of our service offerings;

•

our ability to control our costs and maintain our current cost structure; and

•

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

Our 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, including as a result of pandemics and other macroeconomic conditions, and industry conditions and limiting our ability to withstand competitive pressure;

S-7

•

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

•

limiting our ability to increase our capital expenditures to roll out new services or to upgrade our networks to new technologies, such as 5G;

•

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 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 expand our business as planned, which could have a material adverse effect on our business, financial condition and operating results. Any such risks could also have an adverse effect on the trading prices of the Notes.

To the extent we become party to any hedging arrangements, we may be exposed to credit-related losses in the event of nonperformance by counterparties to such hedging agreements. The primary credit exposure that we would have with respect to such hedging agreements is that a counterparty will default on payments due, which could result in us having to acquire a replacement derivative from a different counterparty at a higher cost or we may be unable to find a suitable replacement. Although counterparties to any hedging agreements may be major financial institutions we would still be exposed to credit risk with these institutions. In addition, any netting and/or set off rights we may have through master netting arrangements with these counterparties may not apply to affiliates of a counterparty with whom we may have various other financial arrangements. If any financial institutions that are parties to any hedging agreements with us were to default on their payment obligations to us, declare bankruptcy or become insolvent, we may be unhedged against the underlying exposures. Any of these risks could have a material adverse effect on our business, financial condition and operating results. Additionally, if the counterparties’ and our obligations under any hedging agreements are required to be secured by cash or U.S. Treasury securities, any posting of collateral by us under such arrangements would negatively impact our liquidity. The modification or termination of any such hedging agreements could also negatively impact our liquidity or other financial metrics.

Some of our debt also has a floating rate of interest linked to various indices. If changes in the indices result in interest rate increases, debt service requirements will increase, which could adversely affect our cash flow and operating results.

In addition, any agreements we have and may continue to enter into to limit our exposure to interest rate increases may not offer complete protection from this risk, and any portion of our indebtedness not subject to such agreements would have full exposure to interest rate increases.

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, including secured debt, as market conditions and contractual obligations permit, which could further reduce the cash available to us 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

S-8

our subsidiaries, subject to specified limitations. In particular, as of June 30, 2024, we had $7.5 billion available for borrowings under the Revolving Credit Facility (as defined under “Description of Other Indebtedness and Certain Financing Transactions—Credit Agreement”). The Notes do not limit our ability to incur unsecured indebtedness, and allow us to incur substantial secured indebtedness. 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 level of indebtedness could adversely affect our business, financial condition and operating results.”

Any repurchases of our common stock under our stock repurchase program or any declaration and payment of any dividends from time to time will reduce funds available for repayment of the Notes.

On September 6, 2023, Parent’s Board of Directors authorized a stockholder return program of up to $19.0 billion through December 31, 2024 (the “2023-2024 Stockholder Return Program”). The 2023-2024 Stockholder Return Program consists of repurchases of shares of Parent’s common stock and the payment of cash dividends, with the amount available under the 2023-2024 Stockholder Return Program for share repurchases reduced by the amount of any cash dividends declared by Parent. As of June 30, 2024, Parent had used $8.1 billion to repurchase shares and paid $2.3 billion in dividends under the 2023-2024 Stockholder Return Program, leaving up to $8.7 billion available for repurchases and dividends through December 31, 2024. Parent expects to pay quarterly dividends totaling approximately $3.0 billion in 2024 and to repurchase up to approximately $7.1 billion of additional shares.

The specific timing and amount of any share repurchases, and the specific timing and amount of any dividend payments, under the 2023-2024 Stockholder Return Program will depend on prevailing share prices, general economic and market conditions, Company performance and other considerations, such as whether the Company determines that there are other uses for the funds currently authorized for the program that would be more advantageous for our business. In addition, the specific timing and amount of any dividend payments are subject to declaration on future dates by the Board in its sole discretion.

The indentures governing the Notes, the Existing T-Mobile Unsecured Notes, the Existing Sprint Unsecured Notes, the Existing ABS Notes and the Existing Sprint Spectrum-Backed Notes do not limit our ability to conduct future repurchases or declare or pay future dividends in any way. The 2023-2024 Stockholder Return Program could impact our cash flows, and any repurchases or dividends would reduce the cash and stockholders’ equity that is available to repay the Notes.

The Notes and the Guarantees will be unsecured and effectively subordinated to the Issuer’s and the guarantors’ existing and future secured indebtedness.

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 Parent, the Issuer and each Subsidiary Guarantor, to the extent of the value of the assets securing such debt. The Notes will also permit us to incur certain 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 that guarantor will be entitled to be paid in full from the assets of the Issuer or guarantor, as applicable, securing that debt before any payment may be made with respect to the Notes or the Guarantees of such guarantor.

Holders of the Notes will participate ratably in any remaining assets with all other holders of the Issuer’s and such guarantor’s unsecured obligations that are not by their terms subordinated to the Notes, based upon the respective amounts owed. 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 obligations of the Issuer and the guarantors.

S-9

The Notes and the Guarantees will be structurally subordinated to the indebtedness and other liabilities of the Issuer’s non-guarantor subsidiaries.

The Notes and the Guarantees will be structurally subordinated to any existing or future liabilities and other obligations of the Issuer’s or the guarantors’ non-guarantor subsidiaries, including the Existing ABS Notes, the Existing Sprint Spectrum-Backed Notes, factoring arrangements and tower obligations. Accordingly, creditors of current and future subsidiaries of the Issuer or the guarantors that are not obligors with respect to the Notes would have claims with respect to the assets of those subsidiaries that would rank structurally senior to the Notes and the Guarantees. 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 would have to be satisfied prior to making any such distribution or payment to the Issuer or the applicable guarantor in respect of direct or indirect equity interests in such subsidiaries. Certain subsidiaries of the Issuer that are prohibited from providing guarantees of the Notes (such as special purpose finance entities and a reinsurance subsidiary), as well as non-wholly owned and immaterial subsidiaries, will not provide guarantees of the Notes. As of June 30, 2024, subsidiaries that will not provide guarantees of the Notes that were included in Parent’s consolidated financial statements as of such date had approximately $11.9 billion of total assets and approximately $5.2 billion in indebtedness and Tower Obligations outstanding. See “Description of Notes—Brief Description of the Notes and the Note Guarantees—The Note Guarantees.”

In order to service our debt, we will require a significant amount of cash, which may not be available to us on attractive terms or at all.

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, including third party rating agency assessments, 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 the Notes, the Existing T-Mobile Unsecured Notes and the Existing Sprint Unsecured Notes, the Credit Agreement, other debt agreements and other agreements we may enter into in the future. Specifically, under our Credit Agreement, we need to maintain a Leverage Ratio (as defined in the Credit Agreement) of 4.50 to 1.00 or less at each fiscal quarter end. 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 satisfy the financial covenants under the Credit Agreement, service our debt or repay our indebtedness in a timely manner or on favorable or commercially reasonable terms, or at all. If we are unable to satisfy such financial covenants or to generate sufficient cash to timely repay our 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. We also may need to refinance certain indebtedness. Disruptions in the financial markets, unfavorable rating agency assessments, the general amount of debt being refinanced at the same time, and our financial position and performance could make it more difficult to obtain debt or equity financing on favorable or commercially reasonable terms or at all. In addition, instability in the global financial markets has from time to time resulted in 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. 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.

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.

S-10

Upon certain events including a change of control triggering event, we may be required to offer to repurchase all of the Existing T-Mobile 2013 Indenture Notes, all of the Existing T-Mobile 2020 Indenture Notes, all of the Existing Sprint Spectrum-Backed Notes and certain of the Existing Sprint Unsecured Notes and to repay amounts owing under the Credit Agreement, and we may not be able to finance such a repurchase or repayment. Not all significant transactions would constitute a change of control triggering event.

We have in the past been the subject of inquiries or offers related to potential strategic transactions (such as an acquisition of the Company), we may be the subject of such inquires or offers in the future, and we may engage in discussions or negotiations regarding such inquiries or offers that may ultimately lead to a transaction. The indentures governing the Existing T-Mobile 2013 Indenture Notes (as defined under “Description of Other Indebtedness and Certain Financing Transactions—Existing T-Mobile Unsecured Notes”), the Existing T-Mobile 2020 Indenture Notes (as defined under “Description of Other Indebtedness and Certain Financing Transactions—Existing T-Mobile Unsecured Notes”), the Existing Sprint Spectrum-Backed Notes and certain of the Existing Sprint Unsecured Notes (but not the Notes) 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 below, the issuer will be required to offer to repurchase all outstanding Existing T-Mobile 2013 Indenture Notes and Existing T-Mobile 2020 Indenture Notes, all outstanding Existing Sprint Spectrum-Backed Notes and the applicable Existing Sprint Unsecured Notes at 101% of the principal amount thereof plus accrued and unpaid interest, if any, to, but not including, the date of repurchase. See “Description of Other Indebtedness and Certain Financing Transactions.” In addition, any such change of control triggering event is expected to cause an event of default under the Credit Agreement, entitling the lenders to declare all amounts outstanding thereunder to be immediately due and payable. Such a change of control would also trigger repayments with respect to our securitization transactions and capital leases. We may not have access to sufficient funds at the time of the change of control triggering event to make the required repurchases of the Existing T-Mobile 2013 Indenture Notes, the Existing T-Mobile 2020 Indenture Notes, the Existing Sprint Spectrum-Backed Notes and the applicable Existing Sprint Unsecured Notes and to repay outstanding amounts under the Credit Agreement, or contractual restrictions may not allow such repurchases or repayments.

Not all change of control transactions would trigger these repurchase or repayment obligations. Specifically, these repurchase or repayment obligations would not be triggered unless both (i) such a transaction constitutes a “Change of Control” under the applicable indenture or credit agreement and (ii) such “Change of Control” is accompanied or followed by certain downgrades or withdrawals of the credit rating with respect to the applicable notes (in the case of any such indenture) or T-Mobile USA (in the case of the Credit Agreement). In the event that we undergo a significant corporate transaction that does not constitute a change of control triggering event such other obligations generally would be permitted to remain outstanding in accordance with their terms.

The failure to purchase the Existing T-Mobile 2013 Indenture Notes, the Existing T-Mobile 2020 Indenture Notes, the Existing Sprint Spectrum-Backed Notes or the applicable Existing Sprint Unsecured Notes, as required under the respective indentures, would result in defaults under such indentures in addition to any events of default under the Credit Agreement resulting from a change of control triggering event thereunder, any of 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 financing arrangements include or will include restrictive covenants that limit our operating flexibility.

The indentures governing the Notes, the Existing T-Mobile Unsecured Notes and the Existing Sprint Unsecured Notes, the Credit Agreement and other financing arrangements, impose (or, in the case of the indentures governing the Notes, will impose) operating and financial restrictions on us. These restrictions, subject in certain cases to customary baskets, exceptions and maintenance and incurrence-based financial tests, together with our debt service obligations, may limit our ability to engage in some transactions and pursue strategic business opportunities.

S-11

In particular, the indentures governing the Existing T-Mobile Unsecured Notes and Existing Sprint Unsecured Notes and the Credit Agreement limit, and the indentures governing the Notes will limit, our and our subsidiaries’ ability to:

•

create certain liens or other encumbrances in respect of indebtedness for borrowed money; and

•

engage in mergers, business combinations or other transactions.

In addition, the Credit Agreement also contains a financial maintenance covenant, requiring the Issuer to maintain a Leverage Ratio of 4.50 to 1.00 or less at each fiscal quarter end.

These restrictions could limit our ability to obtain debt financing, refinance or pay principal on our outstanding indebtedness, complete acquisitions for cash or indebtedness or react to business, economic, market and industry conditions and other 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 the indentures governing the Notes, the Existing T-Mobile Unsecured Notes or the Existing Sprint Unsecured Notes, the Credit Agreement or other 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 and other agreements, giving our lenders and other debt holders the right to terminate any commitments they had made to provide us with further funds or the right to require us to repay all amounts then outstanding plus any interest, fees, penalties or premiums. An event of default may also compel us to sell certain assets securing indebtedness under certain of these agreements. Any of these events would have a material adverse effect on our business, financial condition and operating results.

The Guarantees may be released upon the occurrence of certain events.

A guarantor will be automatically and unconditionally released from its obligations in respect of the Notes of any series:

•

in the case of a Subsidiary Guarantor, at such time as such Subsidiary Guarantor (i) is not, (ii) is released or relieved as, or (iii) ceases (or substantially concurrently will cease) to be, a borrower or guarantor under the Credit Agreement, except by or as a result of payment under such guarantee or direct obligation;

•

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) the Issuer or a Subsidiary Guarantor;

•

in the case of a Subsidiary Guarantor, if for any reason the Subsidiary Guarantor ceases to be a wholly-owned subsidiary of the Issuer; provided that any Subsidiary Guarantor that ceases to constitute a Subsidiary Guarantor or becomes an Excluded Subsidiary solely by virtue of no longer being a wholly-owned subsidiary (a “Partially Disposed Subsidiary”) shall only be released from its Note Guarantee to the extent that the other person taking an equity interest in such Partially Disposed Subsidiary is not an affiliate of the Issuer that is controlled by Parent, Deutsche Telekom or any of their respective subsidiaries or an employee of any of the foregoing;

•

upon the legal defeasance, covenant defeasance, or satisfaction and discharge of the indentures governing the Notes as provided under “Description of Notes—Legal Defeasance and Covenant Defeasance” and “Description of Notes—Satisfaction and Discharge”;

•

upon the liquidation or dissolution of any Subsidiary Guarantor, provided that no event of default under the indentures governing the Notes has occurred that is continuing;

•

upon the merger or consolidation of any guarantor with and into the Issuer or another guarantor that is the surviving person in such merger or consolidation; or

S-12

•

in the case of a Subsidiary Guarantor, if, immediately following such release and any concurrent releases of other guarantees by such Subsidiary Guarantor, the aggregate principal amount of Indebtedness for Borrowed Money (as defined under “Description of Notes—Certain Definitions”) of Subsidiaries that are not Guarantors and not Excluded Subsidiaries (excluding any indebtedness under any Permitted Receivables Financing and any indebtedness of an “Unrestricted Subsidiary” (or the equivalent thereof) under the Credit Agreement or Permitted Receivables Financing Subsidiary) that would remain incurred or issued and outstanding would not exceed $2,000.0 million.

If any such Guarantee is released, no holder of the Notes will have a claim as a creditor against the applicable guarantor, and the indebtedness and other liabilities of such former Subsidiary Guarantor will be structurally senior to the claim of any holder of the Notes. See “Description of Notes—Brief Description of the Notes and the Note Guarantees—The Note Guarantees.”

The Guarantees may be avoidable and therefore not be enforceable because of fraudulent conveyance or fraudulent transfer laws.

The Guarantees may be subject to review and potential avoidance 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 (including the issuance of the Guarantees);

•

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 as currently engaged in or contemplated; 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 avoid 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. In the event of a finding that a fraudulent transfer or conveyance occurred, you may not receive any repayment on the relevant Guarantee (and, consequently, the Notes), or may receive only a partial repayment.

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, such that we cannot be certain as to the standards a court would use to determine whether or not the Issuer or the guarantors were insolvent at the relevant time or, regardless of the insolvency standard applied by the court, that such court would not determine (i) that the Issuer or a guarantor were indeed insolvent on that date, (ii) that any payments to the holders of the Notes (including under the Guarantees) did not constitute preferences, fraudulent transfers or conveyances on other grounds or (iii) whether the Notes or any Guarantees would be subordinated to the Issuer’s or any of the guarantors’ other debt. Generally, however, 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

S-13

•

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.

As a general matter, value is given for a transfer or an obligation if, in exchange for the transfer or obligation, property is transferred or a valid antecedent debt is secured or satisfied. A court would likely find that a guarantor did not receive “reasonably equivalent value” (or fair consideration for) its Guarantee to the extent the guarantor did not obtain a reasonably equivalent benefit directly or indirectly from the issuance of the Notes. Thus, if the Guarantees were legally challenged, any Guarantee could be subject to the claim that, since the Guarantee was incurred for the benefit of the Issuer, and only indirectly for the benefit of the guarantor, the obligations of the applicable guarantor were incurred for less than “reasonably equivalent value” (or fair consideration). Therefore, if a court were to find that the applicable guarantor was insolvent or rendered insolvent by the incurrence of the Guarantee or one of the other conditions above (relating to the guarantor’s financial condition) were satisfied, the court could avoid the obligations under the Guarantees, subordinate them to the applicable guarantor’s other debt or take other action detrimental to the holders of the Notes.

If a Guarantee is avoided as a fraudulent conveyance, fraudulent transfer, or preference, 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, such a loss of a Guarantee generally will constitute an event of default under the indentures governing the Notes and the Existing T-Mobile Unsecured Notes and the Credit Agreement, which events of default would allow the relevant noteholders or lenders to accelerate the amounts due and payable thereunder, and we may not be able to pay any such amounts.

The indentures 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 (as a legal matter or otherwise) to protect the Guarantees from being avoided 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 Florida bankruptcy court decision (which was subsequently reversed by a district court on other grounds and then reinstated by the applicable circuit court of appeals), this kind of provision was found to be ineffective to protect the Guarantees.

In addition, any payment by us pursuant to the Notes or by a guarantor under a Guarantee made at a time we or such guarantor were found to be insolvent could be avoided as a preferential transfer under the U.S. Bankruptcy Code and required to be returned to us or such guarantor or to a fund for the benefit of our or such guarantor’s creditors if such payment is made to an insider within a one-year period prior to a bankruptcy filing or within 90 days for any non-insider party, and such payment would give such insider or non-insider party more than such party would have received in a distribution under the U.S. Bankruptcy Code in a hypothetical Chapter 7 case, subject to applicable defenses.

Finally, as a court of equity, the bankruptcy court may subordinate the claims in respect of the Notes or the Guarantees to other claims against us under the principle of equitable subordination if the court determines that (1) a holder of the Notes or the Guarantees engaged in some type of inequitable conduct, (2) the inequitable conduct resulted in injury to our other creditors or conferred an unfair advantage upon the holders of the Notes and (3) equitable subordination is not inconsistent with the provisions of the U.S. Bankruptcy Code.

The lenders under the Credit Agreement have the discretion to release any guarantors under the Credit Agreement in a variety of circumstances, which could cause those guarantors to be released from their guarantees of each series of the Notes.

For so long as any obligations under the Credit Agreement remain outstanding, any guarantee of the Notes may be released without action by, or consent of, any holder of the Notes, if the related guarantor is no longer a guarantor of obligations under the Credit Agreement or certain other indebtedness of the Issuer or any other

S-14

guarantor (except, in each case, by or as a result of payment under such guarantee or direct obligation). See “Description of Notes—Brief Description of the Notes and the Note Guarantees—The Note Guarantees.” The lenders under the Credit Agreement will have the discretion to release the guarantees under the Credit Agreement in a variety of circumstances. You will not have a claim as a creditor against any entity that is no longer a guarantor of the Notes, and the indebtedness and other liabilities, including trade payables, whether secured or unsecured, of former guarantor subsidiaries will be structurally senior to claims of holders of the Notes.

If we or 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 our, or existing investors’, 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.

Assuming that on June 30, 2024, this offering had been completed, and converting balances in EUR into USD using end of period exchange rates, we would have had outstanding approximately $ billion in aggregate principal amount of debt securities, maturing in 2025 through 2062, $3.0 billion of which would have been senior secured debt securities and $ billion of which would have been senior unsecured debt securities. Deutsche Telekom, which, as of July 26, 2024, controlled the vote of approximately 57.4% of the common stock of Parent, would have held $1.5 billion of these debt securities, maturing in 2028. 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 guarantee that an active trading market for the Notes will exist or that you will be able to sell your Notes.

The Notes will each be a new class of security for which there is no established trading market. An active trading market may not develop for such Notes. 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. The Issuer does 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. If an active public trading market for the Notes does not develop or ceases to exist, the market price and liquidity of the Notes may be adversely affected.

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. Changes in our performance, leverage or industry, or changes in the credit ratings agencies’ ratings methodologies, could lead to ratings downgrades. 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 exists or 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.

S-15

USE OF PROCEEDS

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

See “Description of Other Indebtedness and Certain Financing Transactions” for information on our outstanding indebtedness, including as to interest rate and maturity. Certain of the underwriters and/or their respective affiliates may be lenders under, or holders of, such indebtedness and would therefore receive any portion of the net proceeds of this offering used to repay such indebtedness. See “Underwriting.”

The 6.875% senior notes due 2028 and the 8.750% senior notes due 2032 were issued pursuant to an indenture, dated as of October 1, 1998 (the “1998 Sprint Indenture”), among Sprint Capital Corporation, Sprint and Bank of New York Mellon Trust Company, N.A., as successor to Bank One, N.A., as trustee. The 7.625% senior notes due 2025 and the 7.625% senior notes due 2026 were issued pursuant to an indenture, dated as of September 11, 2013 (the “2013 Sprint Indenture” and collectively with the 1998 Sprint Indenture, the “Existing Sprint Indentures”), among Sprint and The Bank of New York Mellon Trust Company, N.A., as trustee.

The Existing Sprint Indentures, as amended and supplemented with respect to the Existing Sprint Unsecured Notes, contain covenants and other terms, including covenants that, among other things, restrict the ability of Sprint and certain of its subsidiaries to create liens or other encumbrances, and merge, consolidate or sell, or otherwise dispose of, substantially all of their assets. The Existing Sprint Indentures, as so amended and supplemented, also contain customary events of default. These covenants and events of default are subject to a number of important qualifications and exceptions.

Existing Sprint Spectrum Note Facility

The notes set forth in the table below (the “Existing Sprint Spectrum-Backed Notes”) are currently outstanding under Sprint’s $7.0 billion spectrum securitization program (the “Sprint Spectrum Note Facility”) and were issued through a group of bankruptcy-remote special purpose entities (the “Existing Sprint Spectrum Note Entities”) formed for such transaction, each of which are wholly-owned by T-Mobile and non-guarantor “Restricted Subsidiaries” under the indentures governing the Notes, the Existing T-Mobile Unsecured Notes and the Credit Agreement.

The Existing Sprint Spectrum-Backed Notes are secured by a pool of 2.5 GHz and 1.9 GHz spectrum which has been pledged to secure indebtedness available under the Sprint Spectrum Note Facility (the “Sprint Spectrum Portfolio”).

Additional credit enhancement includes a letter of credit supporting an 18-month interest and expense reserve and a pledge of the payment obligations under the Existing Sprint Spectrum Lease.

The Sprint Spectrum Note Facility currently allows for the incurrence of up to $7.0 billion of indebtedness. However, the size of the Sprint Spectrum Note Facility may be increased, subject to the applicable covenants and limitations in the documentation governing the Company’s indebtedness outstanding from time to time.

S-21

The Existing Sprint Spectrum-Backed Notes are initially paid with interest-only payments, followed by amortizing quarterly principal payments, over the periods specified in the table below. The issuers may optionally prepay the outstanding principal amount of all or any tranche of the Existing Sprint Spectrum-Backed Notes in whole on any business day or in part on any payment date, without any obligation to prepay the Existing Sprint Spectrum-Backed Notes of another series or tranche proportionately or otherwise, at a price equal to 100% of the aggregate principal amount of the Existing Sprint Spectrum-Backed Notes prepaid plus accrued and unpaid interest, if any, to the applicable prepayment date, plus, in the case of any such optional prepayment at any time before the date that is one year prior to the anticipated repayment date set forth in the table below, a specified “make-whole” prepayment premium.

TOTAL	$1,771,875,000

Sprint Communications leases the Sprint Spectrum Portfolio from the Existing Sprint Spectrum Note Entities and these lease payments are used to service the indebtedness under the Existing Sprint Spectrum-Backed Notes (the “Existing Sprint Spectrum Lease”).

Each Existing Sprint Spectrum Note Entity is a separate legal entity with its own separate creditors that would be entitled, prior to and upon the liquidation of the Existing Sprint Spectrum Note Entity, to be satisfied out of the Existing Sprint Spectrum Note Entity’s assets prior to any assets of the Existing Sprint Spectrum Note Entity becoming available to its parent entities (including T-Mobile). Accordingly, the assets of the Existing Sprint Spectrum Note Entities would not be available to satisfy the debts and other obligations owed to other creditors of T-Mobile until the obligations of the Existing Sprint Spectrum Note Entities (including under the Existing Sprint Spectrum-Backed Notes) are paid in full.

As the Existing Sprint Spectrum Note Entities are wholly-owned subsidiaries of T-Mobile, these entities will be consolidated and all intercompany activity will be eliminated for accounting purposes.

Credit Agreement

T-Mobile USA is party to an Amended and Restated Credit Agreement (the “Credit Agreement”) by and among T-Mobile USA, as borrower, JPMorgan Chase Bank, N.A., as administrative agent, and the lenders, swingline lenders and L/C issuers party thereto, providing for a $7.5 billion revolving credit facility (the “Revolving Credit Facility”), including a letter of credit sub-facility of up to $1.5 billion and a swingline loan sub-facility of up to $500 million.

Commitments under the Revolving Credit Facility will mature on October 17, 2027, except as otherwise extended or replaced. T-Mobile USA may repay amounts borrowed, reborrow and/or terminate the commitments under the Revolving Credit Facility (in whole or part) at any time without premium or penalty.

Borrowings under the Credit Agreement will bear interest based upon the applicable benchmark rate, depending on the type of loan and, in some cases, T-Mobile USA’s election, plus a margin. The benchmark rates

S-22

consist of (i) the Base Rate, (ii) Adjusted Term SOFR, (iii) the EURIBO Rate, (iv) Daily Simple SONIA, (v) the CDO Rate or (vi) Daily Simple SARON, each as described in the Credit Agreement. Applicable margins range from (x) 0.00% to 0.125% in the case of Base Rate Loans (as defined in the Credit Agreement) and (y) 0.875% to 1.125% in the case of Term Benchmark Loans and RFR Loans (each as defined in the Credit Agreement), in each case depending on the credit rating of T-Mobile USA’s senior unsecured long-term debt (the “Applicable Debt Rating”).

T-Mobile USA will pay an unused commitment fee, calculated quarterly in arrears, at a rate per annum ranging from 0.075% to 0.125% depending on the Applicable Debt Rating.

T-Mobile USA’s obligations under the Credit Agreement are guaranteed by Parent and by all of T-Mobile USA’s wholly-owned domestic restricted subsidiaries (other than certain excluded subsidiaries, including certain designated special purpose finance vehicle entities, insurance subsidiaries and immaterial subsidiaries). The obligations under the Credit Agreement are not secured by any assets of T-Mobile USA, Parent or any of their subsidiaries.

Subject to customary exceptions, the Credit Agreement contains certain limitations on the ability of T-Mobile USA and its restricted subsidiaries to engage in certain activities, including incurrence of liens and consolidations and mergers. The Credit Agreement also contains a financial maintenance covenant, requiring T-Mobile USA to maintain a Leverage Ratio of 4.50 to 1.00 or less at each fiscal quarter end.

Under the Credit Agreement, a Change of Control (as defined in the Credit Agreement) that is accompanied or followed by a downgrade by one or more gradations (including gradations within ratings categories as well as between ratings categories) within a certain period by at least two out of three of Standard & Poor’s Ratings Group, a division of The McGraw Hill Corporation (“S&P”), Moody’s Investors Services, Inc. (“Moody’s”) and Fitch Ratings, Inc. (“Fitch”), where our corporate rating on any day during such period is below the rating by each such rating agency in effect immediately preceding the change of control shall constitute an event of default; provided that in making the relevant decision(s) referred to above to downgrade such ratings, the relevant rating agency announces publicly or confirms in writing during such period that such decision(s) resulted, in whole or in part, from the occurrence (or expected occurrence) of such change of control; provided, further, that, notwithstanding the foregoing, no event of default shall occur under the Credit Agreement if at the time of the applicable downgrade, our corporate rating by at least two out of three of S&P, Moody’s and Fitch is investment grade. If such a change of control accompanied by a downgrade were to occur, we may not have sufficient funds to pay the amounts owing under our Credit Agreement 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.

The Credit Agreement contains customary events of default, including, without limitation, payment defaults, covenant defaults, breaches of certain representations and warranties, cross defaults to certain indebtedness, certain events of bankruptcy and insolvency, certain judgments, a change of control coupled with a ratings downgrade, certain ERISA events and the invalidity of the loan documents. If an event of default occurs and is not cured within any applicable grace period or is not waived, the administrative agent and the lenders will be entitled to take various actions, including, without limitation, the acceleration of amounts due thereunder.

Commercial Paper Program

On July 25, 2023, T-Mobile established an unsecured short-term commercial paper program with the ability to borrow up to $2.0 billion from time to time. This program supplements T-Mobile’s other available external financing arrangements and proceeds are expected to be used for general corporate purposes. As of June 30, 2024, there was no outstanding balance under this program.

S-23

Existing Asset-Backed Securities Facilities

On October 12, 2022, a subsidiary of T-Mobile USA issued $750 million of 4.910% Class A senior asset-backed notes (the “Existing 4.910% ABS Notes”) to third-party investors in a private placement transaction and on February 14, 2024, a subsidiary of T-Mobile USA issued $500 million of 5.050% Class A senior asset-backed notes (collectively with the 4.910% ABS Notes, the “Existing ABS Notes”). The Existing ABS Notes are secured by approximately $1.6 billion of gross EIP receivables and future collections on such receivables. The Existing ABS Notes issued and the assets securing this debt are included on T-Mobile’s Consolidated Balance Sheets.

In connection with issuing the Existing ABS Notes, T-Mobile formed a wholly owned subsidiary, which qualifies as a bankruptcy remote entity (the “ABS BRE”), and trusts (collectively, the “ABS Trusts” and together with the ABS BRE, the “ABS Entities”), in which the ABS BRE holds a residual interest. The ABS BRE’s residual interest in the ABS Trusts represents the rights to all funds not needed to make required payments on the Existing ABS Notes and other related payments and expenses.

Under the terms of the Existing ABS Notes, T-Mobile’s wholly owned subsidiary, T-Mobile Financial LLC (“FinCo”), and certain of T-Mobile’s other wholly owned subsidiaries (collectively, the “Originators”) transfer EIP receivables to the ABS BRE, which in turn transfers such receivables to the ABS Trusts, which issued the Existing ABS Notes. The Class A senior Existing ABS Notes have an expected weighted average life of approximately 2.5 years. Under the terms of each transaction, there is a two-year revolving period during which the Originators may transfer additional receivables to the ABS Entities as collections on the receivables are received. The third-party investors in the Class A senior Existing ABS Notes have legal recourse only to the assets of the respective ABS issuers securing the respective Existing ABS Notes and do not have any recourse to T-Mobile with respect to the payment of principal and interest. The receivables transferred to the ABS issuers will only be available for payment of the respective Existing ABS Notes and other obligations arising from the transactions and will not be available to pay any obligations or claims of T-Mobile’s creditors.

Under parent support agreements, T-Mobile has agreed to guarantee the performance of the obligations of FinCo, which will continue to service the receivables, and the other T-Mobile entities participating in the transactions to the ABS issuers. However, T-Mobile does not guarantee any principal or interest on the Existing ABS Notes or any payments on the underlying EIP receivables.

Existing T-Mobile Tower Transactions

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

Prior to the Merger, Sprint entered into a lease-out and leaseback arrangement with Global Signal Inc., a third party that was subsequently acquired by CCI, that conveyed to CCI the exclusive right to manage and operate approximately 6,400 tower sites (“Master Lease Sites”) via a master prepaid lease. These agreements were assumed upon the close of the Merger, at which point the remaining term of the lease-out was approximately 17 years with no renewal options. CCI has a fixed price purchase option for all (but not less than all) of the leased or subleased sites for approximately $2.3 billion, exercisable one year prior to the expiration of the agreement and ending 120 days prior to the expiration of the agreement. T-Mobile leases back a portion of the space at certain tower sites.

On January 3, 2022, T-Mobile entered into an agreement (the “Crown Agreement”) with CCI. The Crown Agreement extends the current term of the leasebacks by up to 12 years and modifies the leaseback payments for

both of the tower lease arrangements. As a result of the Crown Agreement, there was an increase in T-Mobile’s financing obligation as of the effective date of the agreement of approximately $1.2 billion, with a corresponding decrease to Other long-term liabilities associated with unfavorable contract terms. The modification resulted in a revised interest rate under the effective interest method for the tower obligations: 11.6% for the Existing CCI Tower Lease Arrangement and 5.3% for the Acquired CCI Tower Lease Arrangement. There were no changes made to either of T-Mobile’s master prepaid leases with CCI.

Off-Balance Sheet Arrangements

T-Mobile has factoring arrangements, as amended from time to time, to sell certain EIP accounts receivable and service accounts receivable on a revolving basis as a source of additional liquidity. In 2015, T-Mobile entered into the EIP sale arrangement, which is a revolving facility and currently has a maximum funding commitment of $1.3 billion and on November 14, 2023, T-Mobile extended the scheduled expiration date to November 18, 2024. As of June 30, 2024, the EIP sale arrangement provided funding of $1.3 billion. In 2014, T-Mobile entered into the service accounts receivable arrangement which is also a revolving facility and currently has a maximum funding commitment of $950 million, and on February 27, 2024, extended the scheduled expiration date to February 25, 2025. As of June 30, 2024, the service accounts receivable arrangement provided funding of $775 million. As of June 30, 2024, T-Mobile derecognized net receivables of $2.3 billion upon sale through these arrangements. These arrangements are not reflected on Parent’s consolidated balance sheet.

DESCRIPTION OF NOTES

General

T-Mobile USA, Inc., a Delaware corporation (the “Issuer”), is issuing: $ in aggregate principal amount of % Senior Notes due 20 (the “20 Notes”), $ in aggregate principal amount of % Senior Notes due 20 (the “20 Notes”) and $ in aggregate principal amount of % Senior Notes due 20 (the “20 Notes,” and together with the 20 Notes and the 20 Notes, the “Notes”).

The Notes will be issued under a base indenture (the “Base Indenture”), dated as of September 15, 2022, among the Issuer, Parent and Deutsche Bank Trust Company Americas, as trustee (together with its successors and assigns, the “Trustee”), as supplemented (i) with respect to the 20 Notes by a supplemental indenture dated as of the settlement date of the 20 Notes (the “20 Notes Supplemental Indenture”), (ii) with respect to the 20 Notes by a supplemental indenture dated as of the settlement date of the 20 Notes (the “20 Notes Supplemental Indenture”) and (iii) with respect to the 20 Notes by a supplemental indenture dated as of the settlement date of the 20 Notes (the “20 Notes Supplemental Indenture” and each of the 20 Notes Supplemental Indenture, the 20 Notes Supplemental Indenture and the 20 Notes Supplemental Indenture, with respect to the applicable series, the “Supplemental Indenture”) among the Issuer, Parent, the Subsidiary Guarantors, the Trustee, Deutsche Bank Trust Company Americas, as paying agent and Deutsche Bank Trust Company Americas, as registrar and transfer agent. In this Description of Notes, the term “Indenture” refers to the Base Indenture as supplemented separately by the Supplemental Indenture for the applicable 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”).

In this Description of Notes, (i) the “Issuer” refers only to T-Mobile USA, Inc. and not to any of its Subsidiaries and (ii) “Parent” refers only to T-Mobile US, Inc. and not to any of its Subsidiaries (unless a successor Person shall have become the “Issuer” or “Parent” in accordance with the applicable provisions of the Indenture, if any, and thereafter the “Issuer” or “Parent” shall mean such successor Person).

The obligations and covenants of the Issuer described in this Description of Notes are only of the Issuer, and not of Parent. Although Parent is a guarantor of the Notes, Parent and any of its Subsidiaries that are not the Issuer or the Issuer’s 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 terms of the Indenture in their 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 the Supplemental Indentures, see “Where You Can Find More Information.” You can find the definitions of certain terms used in this Description of Notes under the caption “—Certain Definitions” below. 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 such 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 the Issuer;

S-26

•

will be senior in right of payment to any future indebtedness of the Issuer to the extent that such future indebtedness provides by its terms that it is subordinated in right of payment to the Notes;

•

will be effectively subordinated to all existing and future secured indebtedness of the Issuer, to the extent of the value of the Issuer’s assets securing such indebtedness;

•

will be unconditionally guaranteed on a senior unsecured basis by Parent and the Subsidiary Guarantors.

Assuming that on June 30, 2024, this offering had been completed, and converting balances in EUR into USD using end of period exchange rates, we would have had approximately $ billion of outstanding indebtedness and other obligations, excluding letter of credit obligations, including $ billion of pari passu outstanding unsecured indebtedness. Our pari passu unsecured indebtedness would consist of $ billion of Notes offered hereby, $66.7 billion of Existing T-Mobile Unsecured Notes, $7.5 billion of Existing Sprint Unsecured Notes and $3.7 billion in Tower Obligations. We also would have had $7.5 billion of revolving borrowings available on an unsecured basis under the Credit Agreement. Our effectively senior, secured indebtedness would consist of an aggregate principal amount of $1.8 billion of Existing Sprint Spectrum-Backed Notes outstanding, with up to $5.2 billion remaining available for issuance under the Sprint Spectrum Note Facility (as defined under “Description of Other Indebtedness and Certain Financing Transactions—Existing Sprint Spectrum Note Facility”), and an aggregate principal amount of $1.3 billion of Existing ABS Notes.

The Note Guarantees

The Notes will be guaranteed (i) initially by Parent and any Wholly-Owned Subsidiary of the Issuer that (x) is not an Excluded Subsidiary and (y) is an obligor under the Credit Agreement and (ii) by any future direct or indirect Subsidiary of Parent that is not a Subsidiary of the Issuer or any other Guarantor that directly or indirectly owns Capital Stock of the Issuer. The initial guarantors are expected to include the Issuer’s Domestic Subsidiaries that are Wholly-Owned Subsidiaries of the Issuer (other than special purpose securitization entities, Immaterial Subsidiaries and the Reinsurance Entity), including each of Sprint and its Subsidiaries that meet the foregoing requirements. 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 this Offering and the Notes—The Guarantees may be avoidable and therefore not be enforceable because of fraudulent conveyance or fraudulent transfer laws.”

S-27

Each Note Guarantee of the Notes by a Guarantor:

•

will be a general unsecured, unsubordinated obligation of such Guarantor;

•

will be senior in right of payment to any future indebtedness of that Guarantor to the extent that such future indebtedness provides by its terms that it is subordinated in right of payment to such Guarantor’s Note Guarantee;

•

will be equal in right of payment with any of the Guarantor’s existing and future indebtedness and other liabilities that are not by their terms subordinated in right of payment to the Notes, including, without limitation, obligations under the Credit Agreement, the Existing T-Mobile Unsecured Notes and the Existing Sprint Unsecured Notes;

•

will be effectively subordinated to any Guarantor’s existing and future secured indebtedness to the extent of the value of the assets of such Guarantor securing such indebtedness; and

•

will be structurally subordinated to all of the indebtedness and other obligations of any Subsidiaries of such Guarantor that are not obligors with respect to the Notes. See “Risk Factors—Risks Related to this Offering and the Notes—The Notes and the Guarantees will be unsecured and effectively subordinated to the Issuer’s and the guarantors’ existing and future secured indebtedness” and “Risk Factors—Risks Related to this Offering and the Notes—The Notes and the Guarantees will be structurally subordinated to the indebtedness and other liabilities of the Issuer’s non-guarantor subsidiaries.”

In the event of a bankruptcy, liquidation or reorganization of any non-guarantor Subsidiaries, the non-guarantor Subsidiaries will pay their trade creditors and the holders of their other debt and obligations before they will be able to distribute any of their assets to the Issuer.

The Note Guarantee of a Guarantor will be automatically and unconditionally released in respect of the Notes of any series:

(1)

only in the case of a Subsidiary Guarantor, at such time as such Subsidiary Guarantor (i) is not, (ii) is released or relieved as, or (iii) ceases (or substantially concurrently will cease) to be, a borrower or guarantor under the Credit Agreement, except by or as a result of payment under such guarantee or direct obligation;

(2)

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) the Issuer or a Subsidiary Guarantor;

(3)

only in the case of a Subsidiary Guarantor, if for any reason such Subsidiary Guarantor ceases to be a Wholly-Owned Subsidiary of the Issuer; provided, that any Subsidiary Guarantor that ceases to constitute a Subsidiary Guarantor or becomes an Excluded Subsidiary solely by virtue of no longer being a Wholly-Owned Subsidiary (a “Partially Disposed Subsidiary”) shall only be released from its Note Guarantee to the extent that the other person taking an equity interest in such Partially Disposed Subsidiary is not an affiliate of the Issuer that is controlled by Parent, Deutsche Telekom or any of their respective subsidiaries or an employee of any of the foregoing;

(4)

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”;

(5)

upon the liquidation or dissolution of any Subsidiary Guarantor, provided that no Event of Default has occurred that is continuing;

(6)

upon the merger or consolidation of any Guarantor with and into the Issuer or another Guarantor that is the surviving Person in such merger or consolidation; or

S-28

(7)

in the case of a Subsidiary Guarantor, if, immediately following such release and any concurrent releases of other Guarantees by such Subsidiary Guarantor, the aggregate principal amount of Indebtedness for Borrowed Money of Subsidiaries that are not Guarantors and not Excluded Subsidiaries (excluding any Indebtedness under any Permitted Receivables Financing and any Indebtedness of an “Unrestricted Subsidiary” (or the equivalent thereof) under the Credit Agreement or Permitted Receivables Financing Subsidiary) that would remain incurred or issued and outstanding would not exceed $2,000.0 million.

Principal, Maturity and Interest

The Issuer will issue $ in aggregate principal amount of Notes in this offering, of which $ in aggregate principal amount will be 20 Notes, $ in aggregate principal amount will be 20 Notes and $ in aggregate principal amount will be 20 Notes.

The Issuer may issue further additional Notes of any 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. The Notes of any 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; provided that any additional Notes that are not fungible with the Notes of any series (or with any other additional Notes of that series) for U.S. federal income tax purposes will have a separate CUSIP, ISIN, common code or other identifying number, as applicable.

The Issuer will issue Notes in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof. The 20 Notes will mature on , 20 , the 20 Notes will mature on , 20 and the 20 Notes will mature on , 20 .

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. 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. Interest on the Notes will be computed on the basis of a 360-day year consisting of twelve 30-day months.

Interest on the 20 Notes will accrue at the rate of % per annum. Interest on the 20 Notes will be payable semiannually in arrears on and , commencing on , 20 . The Issuer will make each interest payment to the holders of record of the 20 Notes on the immediately preceding or (whether or not a Business Day).

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”).

S-29

Listing

The Issuer does 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 the Issuer and the Issuer is the paying agent, the 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 the 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, registrar and transfer agent where Notes may be presented for payment. The Issuer may change the paying agent, registrar or transfer agent without prior notice to the holders of the Notes, and the 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.

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. The Issuer will not be required to transfer or exchange any Note selected for redemption. Also, the 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.

Mandatory Redemption; Offers to Purchase; Open Market Purchases

The Issuer will not be required to make any mandatory redemption or sinking fund payments with respect to the Notes.

As market conditions warrant, the Issuer and its affiliates may from time to time seek to purchase their outstanding debt securities or loans, including the Notes, in privately negotiated or open market transactions, by tender offer or otherwise. Subject to any applicable limitations contained in the agreements governing such indebtedness, any purchases made by the Issuer may be funded by the use of cash on its balance sheet or the incurrence of new secured or unsecured debt, including borrowings under credit facilities. The amounts involved in any such purchase transactions, individually or in the aggregate, may be material. Any such purchases may be with respect to a substantial amount of a particular class or series of debt, with the attendant reduction in the trading liquidity of such class or series.

Optional Redemption

Prior to the applicable Par Call Date with respect to each series of Notes, the Issuer may redeem the Notes of such series at its option, in whole or in part, at any time and from time to time, at a redemption price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of:

•

100% of the principal amount of the Notes to be redeemed; and

S-30

•

(a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the redemption date (assuming that such Notes matured on their applicable Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the applicable Treasury Rate (as defined below) plus basis points in the case of the 20 Notes, basis points in the case of the 20 Notes and basis points in the case of the 20 Notes less (b) unpaid interest accrued to the date of redemption (any excess of the amount described in this bullet point over the amount described in the immediately preceding bullet point, the “Make-Whole Premium”);

plus, in either case, accrued and unpaid interest thereon to the redemption date.

On or after the applicable Par Call Date with respect to each series of Notes, the Issuer may redeem the Notes of such series, in whole or in part, at any time or from time to time, at a redemption price equal to 100% of the principal amount of the Notes being redeemed plus accrued and unpaid interest thereon to the redemption date.

“Par Call Date” means (i) with respect to the 20 Notes, , 20 ( months prior to the maturity date of such 20 Notes), (ii) with respect to the 20 Notes, , 20 ( months prior to the maturity date of such 20 Notes) and (iii) with respect to the 20 Notes, , 20 ( months prior to the maturity date of such 20 Notes).

“Treasury Rate” means, with respect to any redemption date, the yield determined by the Issuer in accordance with the following two paragraphs.

The Treasury Rate shall be determined by the Issuer after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third business day preceding the redemption date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily)—H.15” (or any successor designation or publication) (“H.15”) under the caption “U.S. government securities–Treasury constant maturities–Nominal” (or any successor caption or heading). In determining the Treasury Rate, the Issuer shall select, as applicable: (1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the redemption date to the applicable Par Call Date (the “Remaining Life”); or (2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields – one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life – and shall interpolate to the applicable Par Call Date, on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the redemption date.

If on the third business day preceding the redemption date H.15 or any successor designation or publication is no longer published, the Issuer shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second business day preceding such redemption date of the United States Treasury security maturing on, or with a maturity that is closest to, the applicable Par Call Date, as applicable. If there is no United States Treasury security maturing on the applicable Par Call Date, but there are two or more United States Treasury securities with a maturity date equally distant from such Par Call Date, one with a maturity date preceding such Par Call Date, and one with a maturity date following such Par Call Date, the Issuer shall select the United States Treasury security with a maturity date preceding such Par Call Date. If there are two or more United States Treasury securities maturing on the

S-31

applicable Par Call Date, or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Issuer shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.

The Issuer’s actions and determinations in determining the redemption price shall be conclusive and binding for all purposes, absent manifest error.

Notice of any redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with the depositary’s procedures) at least 10 days but not more than 60 days before the redemption date to each holder of Notes to be redeemed.

The Trustee shall have no responsibility whatsoever for calculating the redemption price for any Note.

Unless the Issuer defaults in the payment of the redemption price, interest will cease to accrue on the Notes of a series or portions thereof called for redemption on the applicable redemption date. At or before 10:00 a.m. (New York time) on the redemption date, the Issuer will deposit with the Trustee or a paying agent money sufficient to pay the redemption price of and accrued interest on the Notes to be redeemed on such date. If less than all of the Notes of a series are to be redeemed, the Notes of such series to be redeemed shall be selected in accordance with the procedures of DTC.

For the avoidance of doubt, the requirement to pay any Make-Whole Premium shall not arise in connection with any recovery of amounts due as a result of any breach of any covenant contained in the Indenture or the applicable Notes except where the transaction resulting in such breach was consummated with the intent to breach such covenant.

Prescription

Under New York’s statute of limitations, any legal action to enforce our payment obligations evidenced by the Notes must be commenced within six years after the payment thereof is due; thereafter our payment obligations will generally become unenforceable. In addition, the Indenture will prohibit the Trustee and the holders from accelerating the obligations under the Notes with respect to or as a result of an Event of Default consisting of any action taken, and reported publicly or to holders of Notes, more than two years prior to the declaration of such acceleration.

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 or by lot 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 days but not more than 60 days before the 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. Any such notice of redemption may, at the Issuer’s discretion, state that such redemption is subject to one or more conditions precedent, including, but not limited to, completion of an equity offering, other offering, issuance of Indebtedness or other corporate

S-32

transaction or event. In addition, if such redemption or notice is subject to satisfaction of one or more conditions precedent, such notice shall state that, in the Issuer’s discretion, the redemption date may be delayed until such time as any or all such conditions shall be satisfied (or waived by the Issuer in its sole discretion), or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied (or waived by the Issuer in its sole discretion) by the redemption date (whether the original redemption date or the redemption date so delayed). In addition, the Issuer may provide in such notice that payment of the redemption and performance of the Issuer’s obligations with respect to such redemption may be performed by another Person.

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, 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

Liens

The Issuer will not, and will not permit any Material Subsidiary to, directly or indirectly, create, incur or assume any Lien securing Indebtedness for Borrowed Money upon any of its or any Material Subsidiary’s Principal Property or upon Capital Stock or Indebtedness of any Material Subsidiary that directly owns any Principal Property, except Permitted Liens, unless the Notes are equally and ratably secured with (or, at the Issuer’s option, on a senior basis to) the Indebtedness for Borrowed Money so secured. Any Lien created for the benefit of the holders of the Notes pursuant to this paragraph is required to provide by its terms that such Lien shall be automatically and unconditionally released and discharged upon the release and discharge of the Lien that gave rise to such Lien created for the benefit of the holders of the Notes.

For purposes of determining compliance with this “Liens” covenant, (x) a Lien need not be incurred solely by reference to one category of Permitted Liens, but may be incurred under any combination of such categories (including in part under one such category and in part under any other such category) and (y) in the event that a Lien (or any portion thereof) meets the criteria of one or more of such categories of Permitted Liens, the Issuer shall, in its sole discretion, divide, classify or may subsequently reclassify at any time such Lien (or any portion thereof) in any manner that complies with this “Liens” covenant and the definition of “Permitted Liens.”

Merger, Consolidation or Sale of Assets

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

(1)

either: (a) the Issuer is the surviving corporation; or (b) the Person formed by or surviving any such consolidation or merger (if other than the 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;

(2)

the Person formed by or surviving any such consolidation or merger (if other than the 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 the Issuer to be performed or observed; and

S-33

(3)

immediately after such transaction, no Default or Event of Default exists.

Upon any consolidation or merger, or any sale, assignment, lease, transfer, conveyance or other disposition of all or substantially all of the properties and assets of the Issuer and its 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 the Issuer is merged or to which such sale, assignment, lease, transfer, conveyance or other disposition is made, shall succeed to, and be substituted for, the 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 the “Issuer” shall refer instead to the successor Person and not to the Issuer), and may exercise every right and power of the Issuer under the Indenture with the same effect as if such successor Person had been named as the Issuer therein. When the successor Person assumes all of the Issuer’s obligations under the Indenture, the Issuer shall be discharged from its obligations under the Indenture, including the obligation to pay the principal of or interest or premium, if any, on the Notes.

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

(2)

any consolidation or merger, or any sale, assignment, transfer, conveyance, lease or other disposition of assets between or among the Issuer and its Subsidiaries.

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 Parent 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 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 the 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 Parent is not 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 or incorporated by reference in this prospectus supplement pursuant to which the Notes were offered and sold. The Issuer will comply with §314(a) of the Trust Indenture Act.

If the SEC will not accept Parent’s filings for any reason, the 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).

S-34

Notwithstanding anything herein to the contrary, the Issuer will not be deemed to have failed to comply with any of its obligations hereunder for purposes of clause (4) under “—Events of Default and Remedies” until 150 days after the receipt of the written notice delivered thereunder.

For so long as any Notes remain outstanding, if at any time Parent is not required to file with the SEC the reports required by the preceding paragraphs, the Issuer 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 of 1933, as amended (the “Securities Act”).

Delivery of such reports, information or documents to the Trustee shall be considered for informational purposes only, and the Trustee’s receipt of such reports shall not constitute notice or actual knowledge of any information contained therein or determinable from information contained therein, including the Issuer’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on an officer’s certificate).

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)

(a) is caused by a failure to pay principal of, or interest or premium, if any, on, such Indebtedness at the later of final maturity and the expiration of any related applicable grace period (a “Payment Default”); or

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

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 the greater of $1,500.0 million and 0.675% of Consolidated Total Assets of Parent determined on a pro forma basis for acquisitions, dispositions and Pro Forma Transactions or more, in each case for so long as such failure or acceleration is continuing;

(6)

failure by the Issuer or any of its Significant Subsidiaries (or any of its 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 an amount equal to the greater of $1,500.0 million and

S-35

0.675% of Consolidated Total Assets of Parent determined on a pro forma basis for acquisitions, dispositions and Pro Forma Transactions (to the extent not covered by indemnities or 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;

(7)

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

(9)

except as permitted by the Indenture, (a) any Note Guarantee of a Significant Subsidiary or any group of Subsidiaries of the Issuer that, taken together, would constitute a Significant Subsidiary of the Issuer with respect to Notes of such series (i) is held in any judicial proceeding to be unenforceable or invalid or (ii) ceases for any reason to be in full force and effect, or (b) any Guarantor, or any Person acting on behalf of any such Guarantor, denies or disaffirms its obligations under its Note Guarantee.

In the case of an Event of Default arising from certain events of bankruptcy or insolvency, with respect to the Issuer, any of its Significant Subsidiaries or any group of Subsidiaries of the Issuer that, taken together, would constitute a Significant Subsidiary of the Issuer, 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 any series of Notes, the Trustee or the holders, with a copy to the Trustee, of at least 30% 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; provided that no such declaration may be made with respect to or as a result of any action taken, and reported publicly or to holders of Notes, more than two years prior to such declaration.

Subject to certain limitations, the holders of a majority in aggregate principal amount of the then outstanding Notes of such 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 the principal of, or the interest or premium, if any, on 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 or the Notes Documents at the request or

S-36

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, a holder may pursue a remedy with respect to the Indenture or the Notes of any series only if:

(1)

such holder gives to the Trustee written notice that an Event of Default is continuing;

(2)

holders of at least 30% 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 offer and, if requested, provide to the Trustee security or indemnity satisfactory to the Trustee against any loss, liability or expense to be incurred in compliance with such request;

(4)

the Trustee does not comply with the request within 90 days after receipt of the request and the offer of indemnity or security; 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 all holders of Notes of that series, rescind an acceleration or waive any existing Default or Event of Default in respect of such series of Notes 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.

The Issuer and each Guarantor is required to deliver to the Trustee annually a statement regarding compliance with the Indenture. Within 30 days after becoming aware of any Default or Event of Default, the Issuer is required to deliver to the Trustee a statement specifying such Default or Event of Default unless such Default or Event of Default has been cured or waived in such period.

No Personal Liability of Directors, Officers, Employees and Stockholders

No past, present or future director, officer, member, manager, partner, employee, incorporator or stockholder of any Issuer or any Guarantor, as such, will have any liability for any obligations of any Issuer or any Guarantor 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 and it is the view of the SEC that such a waiver is against public policy.

Legal Defeasance and Covenant Defeasance

The Issuer may at any time, at the option of its Board of Directors evidenced by a resolution set forth in an officer’s certificate, elect to have all of its obligations discharged with respect to the outstanding Notes of any series and all obligations of the Guarantors discharged with respect to their Note Guarantees with respect to such series (“Legal Defeasance”) and cure all then existing Defaults and Events of Defaults 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)

the 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;

S-37

(3)

the rights, powers, trusts, duties, indemnities and immunities of the Trustee, and the Issuer’s and the Guarantors’ obligations in connection therewith; and

(4)

the Legal Defeasance and Covenant Defeasance provisions of the Indenture.

In addition, the Issuer may, at its option and at any time with respect to any series of Notes, elect to have the obligations of the Issuer and the Guarantors released with respect to the provisions of the Indenture described above under the caption “—Certain Covenants” (other than the covenant described 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 any series of Notes in accordance with the Indenture, the Events of Default described under clauses (3) through (9) (in the case of clauses (7) and (8), only with respect to the Issuer’s Subsidiaries) under the caption “—Events of Default and Remedies,” in each case, will no longer constitute an Event of Default.

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

(1)

the 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 the Issuer must specify whether such Notes are being defeased to such stated date for payment or to a particular redemption date; provided that in connection with any Legal Defeasance or Covenant Defeasance that requires the payment of a premium, the amount deposited shall be sufficient for purposes of the Indenture to the extent that an amount is deposited with the Trustee equal to premium calculated as of the date of the deposit, with any deficit as of the maturity date only required to be deposited with the Trustee on or prior to the maturity date;

(2)

in the case of Legal Defeasance, the 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) the Issuer has received from, or there has been published by, the Internal Revenue Service a ruling or (b) since the date Notes of such series were first issued, 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 beneficial owners 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, the 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 the beneficial owners 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 Event of Default has occurred and is continuing with respect to such series of Notes on the date of such deposit (other than an Event of Default resulting from the borrowing of funds, or the imposition of Liens in connection therewith, to be applied to such deposit, or an Event of Default that will be cured by such Covenant Defeasance or Legal Defeasance) and the deposit will not otherwise result in a breach or violation of, or constitute a default under, any material instrument to which the Issuer or any Guarantor is a party or by which the Issuer or any Guarantor is bound;

S-38

(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 the Issuer or any of its Subsidiaries is a party or by which the Issuer or any of its Subsidiaries is bound;

(6)

the Issuer must deliver to the Trustee an officer’s certificate stating that the deposit was not made by the Issuer with the intent of preferring the holders of Notes over the other creditors of the Issuer with the intent of defeating, hindering, delaying or defrauding any creditors of the Issuer or others;

(7)

the Issuer must deliver to the Trustee an officer’s certificate, stating that all conditions precedent relating to the Legal Defeasance or the Covenant Defeasance have been complied with; and

(8)

the 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) and (3) of this paragraph, as applicable, have been complied with.

Amendment, Supplement and Waiver

Except as provided in the next two succeeding paragraphs, the applicable Indenture with respect to the Notes of any series or the related Note Guarantees of the Notes of any 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 a 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 the related 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, 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;

(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;

(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-39

Notwithstanding the preceding, without the consent of any holder of Notes, the Issuer, the Guarantors and the Trustee may amend or supplement the applicable Indenture, the Notes of such series or the related Note Guarantees:

(1)

to cure any ambiguity, omission, mistake, 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 the Issuer’s or a Guarantor’s obligations under the Indenture 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 the 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 or to provide for collateral to secure such series or any Note Guarantee in respect of the Notes of any series;

(6)

to make any change that would provide any additional rights or benefits to the holders of Notes of such series or that does not adversely affect the legal rights under the Indenture of any such holder in any material respect;

(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 Indenture, any Notes or any related Note Guarantees to any provision of this “Description of Notes” section of this prospectus supplement applicable to such Notes at the time of the initial sale thereof, in each case, as conclusively evidenced by an officer’s 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 or collateral 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;

(13)

to allow any Guarantor of the Notes of such series to execute a supplemental indenture providing a Note Guarantee with respect to the Notes of such series; and

(14)

to issue exchange notes and related note guarantees as provided for in any registration rights agreement relating to the notes of any series.

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.

For the avoidance of doubt, no amendment to, or deletion of any of the covenants described under, “—Certain Covenants,” or action taken in compliance with the covenants in effect at the time of such action, shall be deemed to impair or affect any legal rights of any holders of the Notes to receive payment of principal of or premium, if any, or interest on the Notes or to institute suit for the enforcement of any payment on or with respect to such holder’s Notes.

S-40

Satisfaction and Discharge

The applicable Indenture will be discharged and will cease to be of further effect as to the Notes of a series issued thereunder, 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 payment of which money has been deposited in trust and thereafter repaid to the 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 the 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; provided that upon any redemption that requires the payment of a premium, the amount deposited shall be sufficient for purposes of the Indenture to the extent that an amount is deposited with the Trustee equal to the premium calculated as of the date of the notice of redemption, with any deficit as of the redemption date only required to be deposited with the Trustee on or prior to the redemption date;

(2)

the 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

In addition, the Issuer must deliver to the Trustee (a) an officer’s certificate, stating that all conditions precedent set forth in the Indenture have been satisfied, and (b) an opinion of counsel (which opinion of counsel may be subject to customary assumptions, qualifications and exclusions), stating that all conditions precedent set forth in the Indenture have been satisfied.

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 the 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 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 person in the conduct of such person’s own affairs.

S-41

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 the losses, liabilities and expenses that might be incurred by it in compliance with such request or direction.

BOOK-ENTRY SYSTEM; DELIVERY AND FORM

Book-Entry, Delivery and Form

The Notes of each series will be deposited with the Trustee on behalf of The Depository Trust Company (“DTC”), in the form of one or more global notes (the “Global Notes”). The Notes will be issued as fully-registered securities registered in the name of Cede & Co. (DTC’s nominee) or such other name as may be requested by an authorized representative of DTC. So long as DTC or its nominee is the registered owner of a Global Note, DTC or that nominee will be considered the sole owner or holder of the Notes represented by that Global Note for all purposes under the indenture governing the Notes and under the Notes of the applicable series. Except as set forth below, owners of beneficial interests in a Global Note will not be entitled to have Notes represented by that Global Note registered in their names, will not receive or be entitled to receive physical delivery of certificated Notes and will not be considered the owners or holders thereof under the indenture or under the Notes of the applicable series for any purpose, including with respect to the giving of any direction, instruction or approval to the Trustee. Accordingly, each holder owning a beneficial interest in a Global Note must rely on the procedures of DTC and, if that holder is not a direct participant in DTC, on the procedures of the participant through which that holder owns its interest, to receive any payments on or a Note or to exercise any rights of a holder of Notes under the indenture or the Global Note.

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. Beneficial interests in the Global Notes may not be exchanged for Notes in certificated form (“Certificated Notes”) except in the limited circumstances described below. See “—Exchange of Global Notes for Certificated Notes.” Except in the limited circumstances described below, owners of beneficial interests in the Global Notes will not be entitled to receive physical delivery of Notes in certificated form.

In addition, transfers of beneficial interests in the Global Notes will be subject to the applicable rules and procedures of DTC and its direct or indirect participants (including, if applicable, those of Euroclear Bank S.A./N.V., as operator of the Euroclear System (“Euroclear”) or Clearstream Banking, société anonyme (“Clearstream”)), which may change from time to time.

Depositary Procedures

The following description of the operations and procedures of DTC is provided solely as a matter of convenience. These operations and procedures are solely within the control of the respective settlement systems and are subject to changes by them. The Issuer takes no responsibility for these operations and procedures and urges investors to contact the system or their participants directly to discuss these matters.

DTC has advised the Issuer that DTC is a limited-purpose trust company organized under the laws of the State of New York, a “banking organization” within the meaning of the New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the Uniform Commercial Code and a “clearing agency” registered pursuant to the provisions of Section 17A of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). DTC was created to hold securities for its participating organizations (collectively, the “participants”) and to facilitate the clearance and settlement of transactions in those securities between participants through electronic book-entry changes in accounts of its participants. The participants include securities brokers and dealers (including the underwriters), banks, trust companies, clearing corporations and certain other organizations. Access to DTC’s system is also available to other entities such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a participant, either directly or indirectly (collectively, the “indirect participants”). Persons who are not participants may beneficially own securities held by or on behalf of DTC only through the participants or the indirect participants. The ownership interests in, and transfers of ownership interests in, each security held by or on behalf of DTC are recorded on the records of the participants and indirect participants.

S-55

DTC has also advised the Issuer that, pursuant to procedures established by it:

(1)

upon deposit of the Global Notes, DTC will credit the accounts of participants designated by the underwriters with portions of the principal amount of the Global Notes; and

(2)

ownership of these interests in the Global Notes will be shown on, and the transfer of ownership of these interests will be effected only through, records maintained by DTC (with respect to the participants) or by the participants and the indirect participants (with respect to other owners of beneficial interests in the Global Notes).

As long as DTC is the depositary for the notes of the relevant series, you may hold interests in the notes of such series through participants in DTC, including Euroclear and Clearstream. Euroclear and Clearstream will hold interests, in each case, on behalf of their participants through customers’ securities accounts in the names of Euroclear and Clearstream on the books of their respective depositaries, which in turn will hold such interests in customers’ securities accounts in the depositaries’ names on DTC’s books. The Trustee has no liability or responsibility for the action or inaction of DTC or any other depositary. Payments, deliveries, transfers, exchanges, notices and other matters relating to the notes made through Euroclear or Clearstream must comply with the rules and procedures of those systems. Those systems could change their rules and procedures at any time. We have no control over those systems or their participants and we take no responsibility for their activities. Transactions between participants in Euroclear or Clearstream, on the one hand, and other participants in DTC, on the other hand, would also be subject to the rules and procedures of DTC.

Investors will be able to make and receive through Euroclear and Clearstream payments, deliveries, transfers, exchanges, notices and other transactions involving any securities held through those systems only on days when those systems are open for business. Those systems may not be open for business on days when banks, brokers and other institutions are open for business in the United States. In addition, because of time-zone differences, U.S. investors who hold their interests in the notes through these systems and wish to transfer their interests, or to receive or make a payment or delivery or exercise any other right with respect to their interests, on a particular day may find that the transaction will not be effected until the next business day in Luxembourg or Brussels, as applicable. Thus, investors who wish to exercise rights that expire on a particular day may need to act before the expiration date. In addition, investors who hold their interests through both DTC and Euroclear or Clearstream may need to make special arrangements to finance any purchases or sales of their interests between the U.S. and European clearing systems, and those transactions may settle later than transactions within one clearing system.

Except as described below, beneficial owners of an interest in the Global Notes will not have Notes registered in their names, will not receive physical delivery of Notes in certificated form and will not be considered the registered owners or “holders” thereof under the indentures governing the Notes for any purpose.

Payments in respect of the principal of, and interest and premium, if any, on a Global Note registered in the name of DTC or its nominee will be payable to DTC in its capacity as the registered holder under the indentures governing the Notes. Under the terms of the indentures governing the Notes, the Issuer and the Trustee will treat the persons in whose names the Notes, including the Global Notes, are registered as the owners of such Notes for the purpose of receiving payments and for all other purposes. Consequently, neither the Issuer or the Trustee, nor any agent of the Issuer or the Trustee, has or will have any responsibility or liability for:

(1)

any aspect of DTC’s records or any participant’s or indirect participant’s records relating to or payments made on account of beneficial ownership interests in the Global Notes or for maintaining, supervising or reviewing any of DTC’s records or any participant’s or indirect participant’s records relating to the beneficial ownership interests in the Global Notes; or

(2)

any other matter relating to the actions and practices of DTC or any of its participants or indirect participants.

S-56

DTC has advised the Issuer that its current practice, upon receipt of any payment in respect of securities such as the Notes (including principal and interest), is to credit the accounts of the relevant participants with the payment on the payment date unless DTC has reason to believe it will not receive payment on such payment date. Each relevant participant is credited with an amount proportionate to its beneficial ownership of an interest in the principal amount of the relevant security as shown on the records of DTC. Payments by the participants and the indirect participants to the beneficial owners of Notes will be governed by standing instructions and customary practices and will be the responsibility of the participants or the indirect participants and will not be the responsibility of DTC, the Trustee or the Issuer. Neither the Issuer nor the Trustee nor any of their respective agents will be liable for any delay by DTC or any of its participants or indirect participants in identifying the beneficial owners of the Notes, and the Issuer, the Trustee and their respective agents may conclusively rely on and will be protected in relying on instructions from DTC or its nominee for all purposes.

Transfers between participants in DTC will be effected in accordance with DTC’s procedures, and will be settled in same-day funds, and transfers between participants in Euroclear and Clearstream will be effected in accordance with their respective rules and operating procedures.

DTC has advised the Issuer that it will take any action permitted to be taken by a holder of Notes only at the direction of one or more participants to whose account DTC has credited the interests in the Global Notes and only in respect of such portion of the aggregate principal amount of the Notes as to which such participant or participants has or have given such direction. However, if there is an event of default under the Notes, DTC reserves the right to exchange the Global Notes for legended Notes in certificated form, and to distribute such Notes to its participants.

Subject to compliance with the transfer restrictions applicable to the Notes described herein, cross-market transfers between DTC participants, on the one hand, and Euroclear or Clearstream participants, on the other hand, will be effected through DTC in accordance with DTC’s rules on behalf of Euroclear or Clearstream, as the case may be, by their respective depositaries; however, such cross-market transactions will require delivery of instructions to Euroclear or Clearstream, as the case may be, by the counterparty in such system in accordance with the rules and procedures and within the established deadlines (Brussels time) of such system. Euroclear or Clearstream, as the case may be, will, if the transaction meets its settlement requirements, deliver instructions to its respective depositary to take action to effect final settlement on its behalf by delivering or receiving interests in the relevant Global Note in DTC, and making or receiving payment in accordance with normal procedures for same-day funds settlement applicable to DTC. Euroclear participants and Clearstream participants may not deliver instructions directly to the depositories for Euroclear or Clearstream.

Although DTC has agreed to the foregoing procedures in order to facilitate transfers of interests in the Global Notes among participants in DTC, it is under no obligation to perform such procedures, and such procedures may be discontinued or changed at any time. Neither the Issuer nor the Trustee nor any of their respective agents will have any responsibility for the performance by DTC or its participants or indirect participants of their respective obligations under the rules and procedures governing their operations.

Exchange of Global Notes for Certificated Notes

A Global Note is exchangeable for Certificated Notes if:

(1)

DTC (a) notifies the Issuer that it is unwilling or unable to continue as depositary for the Global Notes or (b) has ceased to be a clearing agency registered under the Exchange Act and, in either case, the Issuer fails to appoint a successor depositary within 90 days after receiving such notice or becoming aware that DTC is no longer so registered;

(2)

the Issuer, at its option, notifies the Trustee in writing that the Issuer elects to cause the issuance of the Certificated Notes; or

(3)

there has occurred and is continuing an event of default with respect to the Notes.

S-57

In all cases, Certificated Notes delivered in exchange for any Global Note or beneficial interests in Global Notes will be registered in the names, and issued in any approved denominations, requested by or on behalf of the depositary (in accordance with its customary procedures). Under the terms of the indentures governing the Notes, the Issuer and the Trustee will treat the persons in whose names any Certificated Notes are registered as the owners of such Certificated Notes for the purpose of receiving payments and for all other purposes.

Unless and until we issue the Notes in fully certificated, registered form, (1) you will not be entitled to receive a certificate representing your interest in the Notes; (2) all references in this prospectus supplement or in the accompanying prospectus to actions by holders will refer to actions taken by the depositary upon instructions from their direct participants; and (3) all references in this prospectus supplement or the accompanying prospectus to payments and notices to holders will refer to payments and notices to the depositary, as the registered holder of the Notes, for distribution to you in accordance with its policies and procedures.

Same Day Settlement and Payment

The Issuer will make payments in respect of the Notes represented by the Global Notes (including principal, premium, if any, and interest) by wire transfer of immediately available funds to the accounts specified by the Global Note holder. The Issuer will make all payments of principal, interest and premium, if any, with respect to Certificated Notes by wire transfer of immediately available funds to the accounts specified by the registered holders of the Certificated Notes or, if no such account is specified, by mailing a check to each such holder’s registered address.

The Notes represented by the Global Notes are expected to be made eligible to trade in DTC’s Same-Day Funds Settlement System, and any permitted secondary market trading activity in such Notes will, therefore, be required by DTC to be settled in immediately available funds. The Issuer expects that secondary trading in any Certificated Notes will also be settled in immediately available funds.

Because of time zone differences, the securities account of a Euroclear or Clearstream participant purchasing an interest in a Global Note from a DTC participant will be credited, and any such crediting will be reported to the relevant Euroclear or Clearstream participant, during the securities settlement processing day (which must be a business day for Euroclear and Clearstream) immediately following the settlement date of DTC. DTC has advised the Issuer that cash received in Euroclear or Clearstream as a result of sales of interests in a Global Note by or through a Euroclear or Clearstream participant to a DTC participant will be received with value on the settlement date of DTC but will be available in the relevant Euroclear or Clearstream cash account only as of the business day for Euroclear or Clearstream following DTC’s settlement date.

S-58

CERTAIN U.S. FEDERAL INCOME TAX CONSEQUENCES

The following discussion is a summary of certain U.S. federal income tax consequences of the purchase, ownership and disposition of the Notes issued pursuant to this offering, but does not purport to be a complete analysis of all potential tax effects. The effects of other U.S. federal tax laws, such as estate and gift tax laws, and any applicable state, local or foreign tax laws, are not discussed. This discussion is based on the U.S. Internal Revenue Code of 1986, as amended (the “Code”), Treasury Regulations promulgated thereunder, judicial decisions, and published rulings and administrative pronouncements of the U.S. Internal Revenue Service (the “IRS”), in each case in effect as of the date hereof. These authorities may change or be subject to differing interpretations. Any such change or differing interpretation may be applied retroactively in a manner that could adversely affect a beneficial owner of the Notes. We have not sought and will not seek any rulings from the IRS regarding the matters discussed below. There can be no assurance the IRS or a court will not take a contrary position to that discussed below regarding the U.S. federal income tax consequences of the purchase, ownership and disposition of the Notes.

This discussion is limited to beneficial owners who hold the Notes as “capital assets” within the meaning of Section 1221 of the Code (generally, property held for investment). In addition, this discussion is limited to persons purchasing the Notes for cash at original issue and at the original “issue price” of the applicable series of the Notes within the meaning of Section 1273 of the Code (i.e., the first price at which a substantial amount of the Notes of such series is sold for money to investors, other than bond houses, brokers, or similar persons or organizations acting in the capacity of underwriters, placement agents or wholesalers). This discussion does not address all U.S. federal income tax consequences relevant to a beneficial owner’s particular circumstances, including the impact of the Medicare contribution tax on net investment income. In addition, it does not address consequences relevant to beneficial owners subject to special rules, including, without limitation:

•

U.S. expatriates and former citizens or long-term residents of the United States;

•

persons subject to the alternative minimum tax;

•

U.S. Holders (as defined below) whose functional currency is not the U.S. dollar;

•

persons holding the Notes as part of a hedge, straddle or other risk reduction strategy or as part of a conversion, constructive sale, wash sale or other integrated transaction;

•

banks, insurance companies, and other financial institutions;

•

real estate investment trusts or regulated investment companies;

•

brokers, dealers or traders in securities or currencies;

•

“controlled foreign corporations,” “passive foreign investment companies,” and corporations that accumulate earnings to avoid U.S. federal income tax;

•

U.S. Holders that hold Notes through non-U.S. brokers or other non-U.S. intermediaries;

•

S corporations, partnerships or other entities or arrangements treated as partnerships for U.S. federal income tax purposes (and investors therein); and

•

tax-exempt entities, retirement plans, individual retirement accounts, tax-deferred accounts, and governmental organizations.

U.S. Holders that use an accrual method of accounting for U.S. federal income tax purposes generally are required to include certain amounts in income no later than the time such amounts are reflected on certain applicable financial statements. The application of this rule may require the accrual of income earlier than would be the case under the general U.S. federal income tax rules described below. U.S. Holders that use an accrual method of accounting for U.S. federal income tax purposes should consult with their tax advisors regarding the potential applicability of this rule to their particular situation. The remainder of this discussion does not address the application of the foregoing rule.

S-59

If an entity or arrangement treated as a partnership for U.S. federal income tax purposes holds the Notes, the U.S. federal income tax treatment of a partner in the partnership generally will depend on the status of the partner, the activities of the partnership and certain determinations made at the partner level. Accordingly, entities or arrangements classified as partnerships for U.S. federal income tax purposes considering an investment in the Notes and the partners in such partnerships should consult their tax advisors regarding the U.S. federal income tax consequences to them.

THIS DISCUSSION IS FOR INFORMATION PURPOSES ONLY AND IS NOT TAX ADVICE. INVESTORS SHOULD CONSULT THEIR TAX ADVISORS WITH RESPECT TO THE APPLICATION OF THE U.S. FEDERAL INCOME TAX LAWS TO THEIR PARTICULAR SITUATIONS AS WELL AS ANY TAX CONSEQUENCES OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF THE NOTES ARISING UNDER OTHER U.S. FEDERAL TAX LAWS (INCLUDING ESTATE AND GIFT TAX LAWS), UNDER THE LAWS OF ANY STATE, LOCAL OR NON-U.S. TAXING JURISDICTION OR UNDER ANY APPLICABLE TAX TREATY.

Tax Consequences Applicable to U.S. Holders

Definition of a U.S. Holder

For purposes of this discussion, a “U.S. Holder” is a beneficial owner of a Note that, for U.S. federal income tax purposes, is treated as:

•

an individual who is a citizen or resident of the United States;

•

a corporation created or organized under the laws of the United States, any state thereof, or the District of Columbia;

•

an estate, the income of which is subject to U.S. federal income tax regardless of its source; or

•

a trust if (1) a court within the United States is able to exercise primary supervision over the administration of the trust and one or more “United States persons” (within the meaning of Section 7701(a)(30) of the Code) have the authority to control all substantial decisions of the trust, or (2) the trust has a valid election in effect to be treated as a United States person for U.S. federal income tax purposes.

Payments of Interest

Interest on a Note generally will be included in a U.S. Holder’s gross income and taxed as ordinary income at the time such interest is received or accrued, in accordance with such U.S. Holder’s regular method of tax accounting for U.S. federal income tax purposes.

Sale or Other Taxable Disposition

A U.S. Holder will recognize gain or loss, if any, on the sale, exchange, redemption, retirement or other taxable disposition of a Note. The amount of such gain or loss will generally equal the difference between the amount received for the Note in cash or other property valued at fair market value (less amounts attributable to any accrued but unpaid interest, which will be taxable as interest to the extent not previously included in income in the manner described above under “—Payments of Interest”) and the U.S. Holder’s adjusted tax basis in the Note. A U.S. Holder’s adjusted tax basis in a Note generally will be equal to the amount the U.S. Holder paid for the Note. Any gain or loss will be capital gain or loss, and will be long-term capital gain or loss if the U.S. Holder has held the Note for more than one year at the time of sale or other taxable disposition. Otherwise, such gain or loss will be short-term capital gain or loss. Long-term capital gains recognized by certain non-corporate U.S. Holders, including individuals, generally will be taxable at a reduced rate. The deductibility of capital losses is subject to limitations.

S-60

Information Reporting and Backup Withholding

A U.S. Holder generally will be subject to information reporting and backup withholding when such holder receives payments of interest on a Note or receives proceeds from the sale or other taxable disposition of a Note (including a redemption or retirement of a Note). Certain U.S. Holders are exempt from backup withholding, including corporations and certain tax-exempt entities, provided that such U.S. Holders furnish appropriate evidence of exemption. A U.S. Holder will be subject to backup withholding if such holder is not otherwise exempt and fails to furnish the holder’s taxpayer identification number, which for an individual is ordinarily his or her social security number, or otherwise comply with the requirements of the backup withholding rules. Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules may be allowed as a refund or a credit against a U.S. Holder’s U.S. federal income tax liability, if any, provided the required information is timely furnished to the IRS. U.S. Holders should consult their tax advisors regarding their qualification for an exemption from backup withholding and the procedures for obtaining such an exemption.

Tax Consequences Applicable to Non-U.S. Holders

Definition of a Non-U.S. Holder

For purposes of this discussion, a “Non-U.S. Holder” is a beneficial owner of a Note that is, for U.S. federal income tax purposes, an individual, corporation, estate or trust that is not a U.S. Holder.

Payments of Interest

Subject to the discussions of backup withholding and FATCA below, interest paid on a Note to a Non-U.S. Holder that is not effectively connected with the Non-U.S. Holder’s conduct of a trade or business within the United States generally will not be subject to U.S. federal income tax or withholding tax provided that:

•

the Non-U.S. Holder does not, actually or constructively, own 10% or more of the total combined voting power of all classes of our voting stock within the meaning of Section 871(h)(3) of the Code;

•

the Non-U.S. Holder is not a controlled foreign corporation related to us through actual or constructive stock ownership (as provided in the Code);

•

the Non-U.S. Holder is not a bank receiving interest described in Section 881(c)(3)(A) of the Code; and

•

the Non-U.S. Holder provides a signed written statement on an IRS Form W-8BEN or W-8BEN-E (or other applicable form), which can be reliably associated with the Non-U.S. Holder, certifying that the Non-U.S. Holder is not a United States person to (1) the applicable withholding agent, (2) a securities clearing organization, bank or other financial institution that holds customers’ securities in the ordinary course of its trade or business and holds the Note on behalf of the Non-U.S. Holder and certifies to the applicable withholding agent (directly or through one or more similarly situated financial institutions) that it has received from the Non-U.S. Holder (or another financial institution) the signed written statement described above and provides a copy of such statement; or (3) a “qualified intermediary” (within the meaning of applicable Treasury Regulations), provided that certain conditions are satisfied.

If a Non-U.S. Holder does not satisfy the requirements described above, such Non-U.S. Holder will be subject to a U.S. federal withholding tax of 30% (or such lower rate specified by an applicable income tax treaty) on interest that is not effectively connected with the Non-U.S. Holder’s conduct of a trade or business within the United States. To claim an entitlement to a reduction in or exemption from withholding on such interest as a result of an applicable tax treaty, the Non-U.S. Holder must provide the applicable withholding agent with a properly executed IRS Form W-8BEN or W-8BEN-E (or other applicable documentation) claiming a reduction in or exemption from withholding tax under an income tax treaty between the United States and the country in which the Non-U.S. Holder resides or is established. Non-U.S. Holders should consult their tax advisors regarding their entitlement to benefits under any applicable income tax treaty.

S-61

If interest paid to a Non-U.S. Holder is effectively connected with the Non-U.S. Holder’s conduct of a trade or business within the United States, the Non-U.S. Holder will be exempt from the U.S. federal withholding tax described above, unless an applicable income tax treaty provides otherwise. To claim the exemption, the Non-U.S. Holder must furnish to the applicable withholding agent a valid IRS Form W-8ECI (or other applicable form), certifying that interest paid on a Note is not subject to withholding tax because it is effectively connected with the conduct by the Non-U.S. Holder of a trade or business within the United States.

Any such effectively connected interest generally will be subject to U.S. federal income tax at the regular tax rates in the same manner as if the Non-U.S. Holder were a U.S. person, unless an applicable income tax treaty provides otherwise. A Non-U.S. Holder that is a corporation also may be subject to a branch profits tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty) on its effectively connected earnings and profits, as adjusted for certain items.

The certifications described above must be provided to the applicable withholding agent prior to the payment of interest and must be updated periodically.

Sale or Other Taxable Disposition

Subject to the discussions of backup withholding and FATCA below, a Non-U.S. Holder will not be subject to U.S. federal income tax on any gain recognized upon the sale, exchange, redemption, retirement or other taxable disposition of a Note (excluding any amount allocable to accrued and unpaid interest, which generally will be treated as interest subject to the rules discussed above in “—Payments of Interest”) unless:

•

the gain is effectively connected with the Non-U.S. Holder’s conduct of a trade or business within the United States (and, if required by an applicable income tax treaty, the Non-U.S. Holder maintains a permanent establishment in the United States to which such gain is attributable); or

•

the Non-U.S. Holder is an individual present in the United States for 183 days or more during the taxable year of the disposition and certain other requirements are met.

Gain described in the first bullet point above generally will be subject to U.S. federal income tax on a net income basis at the regular tax rates in the same manner as if the Non-U.S. Holder were a U.S. person. A Non-U.S. Holder that is a foreign corporation also may be subject to a branch profits tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty) on its effectively connected earnings and profits, as adjusted for certain items.

Gain described in the second bullet point above generally will be subject to U.S. federal income tax at a rate of 30% (even though the individual is not considered a resident of the United States), which may be offset by certain U.S. source capital losses of the Non-U.S. Holder, provided the Non-U.S. Holder has timely filed U.S. federal income tax returns with respect to such losses.

Non-U.S. Holders should consult their tax advisors regarding any applicable income tax treaties that may provide for different rules.

Information Reporting and Backup Withholding

Payments of interest generally will not be subject to backup withholding, provided the holder certifies its non-U.S. status as described above under “—Payments of Interest.” However, information returns are required to be filed with the IRS in connection with any interest paid to the Non-U.S. Holder, regardless of whether any tax was actually withheld. In addition, proceeds of the sale or other taxable disposition of a Note (including a retirement or redemption of the Note) within the United States or conducted through certain U.S. -related brokers generally will be subject to backup withholding and/or information reporting, unless the applicable withholding agent receives the statement described above or the beneficial owner otherwise establishes an exemption. Proceeds of a disposition of a Note paid outside the United States and conducted through a non-U.S. office of a non-U.S. broker generally will not be subject to backup withholding or information reporting.

S-62

Copies of information returns that are filed with the IRS may also be made available under the provisions of an applicable treaty or agreement to the tax authorities of the country in which the Non-U.S. Holder resides or is established.

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

Additional Withholding Tax on Payments Made to Foreign Accounts

Sections 1471 to 1474 of the Code and related Treasury guidance (commonly referred to as the Foreign Account Tax Compliance Act, or “FATCA”) generally impose U.S. federal withholding tax at a 30% rate on payments made to non-U.S. entities (whether such entities are the beneficial owners or intermediaries) of U.S. -source interest (including interest on the Notes) and gross proceeds from the sale or other disposition (including a retirement or redemption) of an obligation that produces U.S. -source interest (including a disposition of the Notes). This withholding obligation applies unless the foreign entity complies with (1) certain information reporting requirements regarding its U.S. account holders and U.S. owners and (2) certain withholding obligations regarding certain payments to its account holders and certain other persons, or the foreign entity otherwise qualifies for an exemption from these rules. Accordingly, the entity through which a U.S. Holder or a Non-U.S. Holder holds its Notes will affect the determination of whether such withholding is required. Under recently proposed Treasury Regulations that may be relied upon pending finalization, the withholding tax on gross proceeds would be eliminated and, consequently, FATCA withholding on gross proceeds is not expected to apply. We will not pay additional amounts to U.S. Holders or Non-U.S. Holders in respect of amounts withheld under FATCA. Foreign financial institutions located in jurisdictions that have an intergovernmental agreement with the United States governing FATCA may be subject to different rules.

Prospective investors should consult their tax advisors regarding the potential application of withholding under FATCA to their investment in the Notes.

We have agreed to indemnify the underwriters and their controlling persons against certain liabilities in connection with this offering, including liabilities under the Securities Act of 1933, as amended, or to contribute to payments the underwriters may be required to make in respect of those liabilities.

Commissions and Discounts

The representatives have advised us that the underwriters propose initially to offer the Notes to the public at the public offering prices set forth on the cover page of this prospectus supplement. After the initial offering, the public offering prices or any other terms of this offering may be changed. The underwriters may offer and sell Notes through certain of their affiliates. The underwriters reserve the right to reject an order of Notes in whole or in part.

We estimate that our costs, fees and expenses in connection with this offering, other than underwriting discounts and commissions, will be $ million.

No Market for the Notes

The Notes will each be a new class of security for which there is no established trading market. The Issuer does 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 Issuer has been advised by the underwriters that they presently intend to make a market in the Notes after completion of this offering. The underwriters are not obligated, however, to make a market in the Notes and any such market making may be discontinued at any time at the sole discretion of the underwriters. In addition, market-making activities will be subject to the limits imposed by the Exchange Act, and may be limited. Accordingly, no assurance can be given as to liquidity of the trading market for the Notes or that an active public market for the Notes will develop. If an active public trading market for the Notes does not develop or ceases to exist, the market price and liquidity of the Notes may be adversely affected. If the Notes are traded, they may trade at a discount from their initial offering price, depending on prevailing interest rates, the market for similar securities, our operating performance and financial condition, general economic conditions and other factors.

S-64

No Sale of Similar Securities

We have agreed that we will not, after the date of this prospectus supplement and until the issue date of the Notes, without first obtaining the prior written consent of the representatives, offer, sell, contract to sell or otherwise dispose of any debt securities issued or guaranteed by the Issuer, Parent or any of the Subsidiary Guarantors and having a tenor of more than one year.

Settlement

We expect that delivery of the Notes will be made to investors on or about September , 2024, which will be the third business day following the date of this prospectus supplement (such settlement being referred to as “T+3”). Under Rule 15c6-1 under the Exchange Act, trades in the secondary market generally are required to settle in one business day unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the Notes more than one business day prior to the settlement date will be required, by virtue of the fact that the Notes initially will settle in T+3, to specify an alternative settlement cycle at the time of any such trade to prevent failed settlement and should consult their own advisors.

Stabilization and Short Positions

In connection with the offering of the Notes, the underwriters, or persons acting on their behalf, may engage in transactions that stabilize, maintain or otherwise affect the price of the Notes. Specifically, the underwriters, or persons acting on their behalf, may bid for and purchase Notes in the open market to stabilize the price of the Notes. The underwriters, or persons acting on their behalf, may also over-allot the offering of the Notes, creating a syndicate short position, and may bid for and purchase Notes in the open market to cover the syndicate short position. In addition, the underwriters, or persons acting on their behalf, may bid for and purchase Notes in market-making transactions as permitted by applicable laws and regulations and impose penalty bids. Any of these activities may have the effect of preventing or retarding a decline in the market price of the Notes. These activities may also stabilize or maintain the respective market price of the Notes above market levels that may otherwise prevail. The underwriters are not required to engage in these activities, and may end these activities at any time. Accordingly, no assurance can be given as to the liquidity of, or trading markets for, the Notes.

Neither the Issuer nor any of the underwriters make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of the Notes. In addition, neither the Issuer nor any of the underwriters make any representation that the representatives will engage in these transactions or that these transactions, once commenced, will not be discontinued without notice.

Other Relationships

The underwriters and their respective affiliates are full service financial institutions engaged in various activities, which may include sales and trading, commercial and investment banking, advisory, investment management, investment research and principal investment, hedging, market making, brokerage and other financial and non-financial activities and services. Some of the underwriters and their affiliates have engaged in, and may in the future engage in, investment banking and other commercial dealings in the ordinary course of business with us or our affiliates. They have received, or may in the future receive, customary fees and commissions for these transactions. In addition, in the ordinary course of their business activities, the underwriters and their affiliates may make or hold a broad array of investments and 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. Such investments and securities activities may involve securities and/or instruments of ours or our affiliates. The underwriters and their affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments. Affiliates of certain of the underwriters act as lenders and/or agents under the Credit Agreement or holders of our other indebtedness, and would therefore receive any portion of the net proceeds of this offering used to repay such indebtedness. See “Use of Proceeds.”

S-65

If any of the underwriters or their affiliates have a lending relationship with us, certain of those underwriters or their affiliates are likely to hedge and certain other of those underwriters or their affiliates may hedge their credit exposure to us consistent with their customary risk management policies. Typically, they would hedge such exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in our securities, including potentially the notes offered hereby. Any such credit default swaps or short positions could adversely affect future trading prices of the notes offered hereby.

This prospectus is part of a registration statement on Form S-3 under the Securities Act of 1933, as amended (the “Securities Act”), that we filed with the Securities and Exchange Commission (the “SEC”) using the “shelf” registration process. Under this shelf registration process, we or certain selling securityholders may offer and sell any combination of the securities described in this prospectus in one or more offerings. This prospectus provides you with a general description of the securities we or certain selling securityholders may offer. Each time we use this prospectus to offer securities, we will provide you with a prospectus supplement that will describe the specific amounts, prices, and terms of the securities being offered. A prospectus supplement may add, update or change information contained in this prospectus.

DESCRIPTION OF CAPITAL STOCK

The following summary does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the Company’s Certificate of Incorporation, the Company’s Seventh Amended and Restated Bylaws (“Bylaws”), the Second Amended and Restated Stockholders’ Agreement, dated as of June 22, 2020 (the “Stockholders’ Agreement”), by and among the Company, Deutsche Telekom and SoftBank, the Proxy, Lock-up and ROFR Agreement, dated as of April 1, 2020, by and between Deutsche Telekom and SoftBank (the “SoftBank Proxy Agreement”) and the Proxy, Lock-up and ROFR Agreement, dated as of June 22, 2020, (the “Claure Proxy Agreement” and together with the SoftBank Proxy Agreement, the “Proxy Agreements”), by and among Deutsche Telekom, Claure Mobile LLC (“CM LLC”), and Marcelo Claure, each of which are exhibits to our Annual Report on Form 10- K, and applicable provisions of the General Corporation Law of the State of Delaware.

General

Pursuant to our Certificate of Incorporation, the total number of shares of capital stock that the Company is authorized to issue is two billion one hundred million (2,100,000,000), comprising two billion (2,000,000,000) shares of common stock with a par value of $0.00001 per share and one hundred million (100,000,000) shares of preferred stock with a par value of $0.00001 per share. The rights and privileges of holders of common stock are subject to the rights and privileges of the holders of any series of preferred stock that we may issue in the future.

Common Stock

Voting Rights

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.

Classification of the Board of Directors

All of the directors of the Company shall be of one class and shall be elected annually. Each director shall hold office until the next annual meeting of stockholders and shall serve until his successor shall have been duly elected and qualified or until his earlier death, resignation, retirement, disqualification or removal.

Dividend, Liquidation and Other Rights

Subject to the prior rights of holders of all classes of stock at the time outstanding having prior rights as to dividends (including holders of 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, after satisfaction of all of our liabilities and subject to the prior rights of holders of all classes of stock at the time outstanding having prior rights as to distributions in the event of liquidation, dissolution or winding up (including holders of preferred stock), be entitled to a ratable share of any distribution to stockholders. 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 Provisions

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

specified Federal Communications Commission (“FCC”) rules or regulations, we may, at the option of our 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 such 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 SoftBank. If any waivers or approvals are required from the FCC in order for Deutsche Telekom to acquire or hold any shares of our common stock or preferred stock, Deutsche Telekom is required by the Certificate of Incorporation to cooperate to secure such waivers or approvals and abide by any conditions related to such waivers or approvals. If any waivers or approvals are required from the FCC in order for SoftBank to acquire or hold any shares of our common stock or preferred stock, SoftBank are required by the Certificate of Incorporation to 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 our 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, 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 our 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 our 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.

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

Delaware law

The Company is subject to Section 203 of the General Corporation Law of the State of Delaware (“Section 203”), which generally provides that an “interested stockholder” cannot engage in a “business combination” (as those terms are defined in Section 203) with the Company for a period of three years after the stockholder 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.

Certain Other Provisions of 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 by stockholders for the election of directors to serve on our board of directors and for proposing other items of business 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 the aggregate voting power of all outstanding shares of our capital stock then entitled to vote on amendments to our Bylaws. 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 chairperson of our board of directors 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.

•

Stockholder Action by Written Consent. Our Certificate of Incorporation provides that as long as Deutsche Telekom beneficially owns 25% or more of the outstanding common stock and any other securities of the Company that are entitled to vote in the election of directors (collectively, “T-Mobile Voting Securities”), stockholders may act by written consent in lieu of a meeting.

•

Board representation. Our Certificate of Incorporation incorporates provisions of the Stockholders’ Agreement providing Deutsche Telekom with certain rights to designate a number of designees to our board of directors as described below under “Stockholders’ Agreement.”

•

Special consent rights. Our Certificate of Incorporation provides Deutsche Telekom with the same consent rights as are set forth in the Stockholders’ Agreement with respect to our ability to take certain actions as described below under “Stockholders’ Agreement”.

•

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 stock entitled to vote thereon.

Stockholders’ Agreement

Pursuant to the Stockholders’ Agreement, Deutsche Telekom has certain rights to designate individuals to be nominees for election to our board of directors and certain committees thereof. Pursuant to the Stockholders’ Agreement, at all times when Deutsche Telekom, SoftBank and Marcelo Claure beneficially own at least 50% of the outstanding T-Mobile Voting Securities in the aggregate and any such T-Mobile Voting Security continues to be subject to a voting proxy under either of the Proxy Agreements, (i) our board of directors will consist of a total of 14 directors (except in cases of resignations, retirements, deaths or removals, pending any new appointments), (ii) Deutsche Telekom has the right to designate a specified number of nominees for election to our board of directors in accordance with the terms of the Stockholders’ Agreement, subject to certain requirements, including requirements with respect to the “independence” of certain nominees under applicable stock exchange listing standards and rules of the SEC, (iii) the chairperson of our board of directors will be a Deutsche Telekom designee and (iv) our board of directors will have certain committees, which committees will be comprised in the manner specified in the Stockholders’ Agreement. The Stockholders’ Agreement further provides that at all times when Deutsche Telekom, SoftBank and Marcelo Claure beneficially own less than 50% of the outstanding T-Mobile Voting Securities in the aggregate or no T-Mobile Voting Security continues to be subject to a voting proxy under either of the Proxy Agreements, then, in each case, (i) Deutsche Telekom has the right to designate a number of nominees for election to our board of directors equal to the percentage of T-Mobile Voting Securities that it beneficially owns (provided that such percentage is 10% or more) multiplied by the number of directors on our board of directors, rounded to the nearest whole number greater than zero and (ii) board committees will comprise designees of Deutsche Telekom in percentages determined by the Stockholders’ Agreement, subject to certain exceptions.

As of the date of this prospectus, Deutsche Telekom has the right to designate ten individuals to be nominees for election to our board of directors. As of the date of this prospectus, our board of directors consists of a total of 13 directors, including nine directors designated by Deutsche Telekom and G. Michael Sievert, our President and Chief Executive Officer.

In addition, pursuant to the Stockholders’ Agreement, until the DT Specified Actions Termination Date (as described below and defined in the Stockholders’ Agreement), we are restricted from taking 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 to which Deutsche Telekom or any of its affiliates is a party, (c) acquiring or disposing of assets or entering into mergers or similar acquisitions in excess of $1.0 billion, (d) changing the size of our

board of directors, (e) subject to certain exceptions, issuing equity of 10% or more of the then-outstanding shares of our common stock, or issuing equity to redeem debt held by Deutsche Telekom, (f) 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. The DT Specified Actions Termination Date would occur only after Deutsche Telekom ceases to beneficially own 30% or more of the outstanding T-Mobile Voting Securities (and in certain cases only if Deutsche Telekom does not subsequently re-acquire such beneficial ownership within a specified period). In addition, we have agreed that, without the prior written consent of Deutsche Telekom, we will not amend our Certificate of Incorporation and Bylaws in any manner that could limit, restrict or adversely affect Deutsche Telekom’s rights under the Stockholders’ Agreement for as long as Deutsche Telekom beneficially owns 5% or more of the outstanding T-Mobile Voting Securities.

During the term of the Stockholders’ Agreement, Deutsche Telekom is not permitted to, and is required to cause the Deutsche Telekom designees then serving as directors on our board of directors not to, support, enter into or vote in favor of (a) any transaction in which the aggregate amount involved exceeds, or may be expected to exceed, $120,000 between or involving both (i) the Company and (ii) Deutsche Telekom and its affiliates, unless such transaction is approved unanimously by the audit committee of our board of directors or, for amendments to previously approved transactions, by a majority of the audit committee of our board of directors.

Pursuant to the Stockholders’ Agreement, Deutsche Telekom and its affiliates are generally prohibited from acquiring common stock that would cause their collective beneficial ownership to exceed a certain percentage of the outstanding T-Mobile Voting Securities unless such acquiring stockholder makes an offer to acquire all of the then-remaining outstanding shares of our 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 either (i) accepted or approved by a majority of the directors on our board of directors, which majority includes a majority of the directors who are not affiliated with Deutsche Telekom or SoftBank under the terms of the Stockholders’ Agreement (the “Required Approval”), or (ii) accepted or approved by holders (other than Deutsche Telekom, SoftBank and their respective affiliates) of a majority of the shares of our common stock (other than shares held by Deutsche Telekom, SoftBank and their respective affiliates). Deutsche Telekom is also prohibited from transferring any shares of our common stock in any transaction that would result in the transferee owning more than 30% of the outstanding shares of our common stock, subject to certain exceptions, unless the transfer is approved by our board of directors (including the Required Approval) or the transferee offers to acquire all of the then outstanding shares of our common stock at the same price and on the same terms and conditions as the proposed transfer.

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. In addition, Deutsche Telekom has piggyback registration rights with respect to any offering that we initiate. 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 applicable, 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.

The Stockholders’ Agreement sets forth certain additional rights and obligations of Deutsche Telekom, including information rights and non-competition restrictions.

The foregoing summary of the Amended and Restated Stockholders’ Agreement does not purport to be complete and is subject to, and qualified in its entirety by, the Amended and Restated Stockholders’ Agreement, which is included as Exhibit 4.2 hereto.

Proxy Agreements

The SoftBank Proxy Agreement establishes between Deutsche Telekom and SoftBank certain rights and obligations in respect of the shares of common stock owned by each of Deutsche Telekom, SoftBank and certain

of their respective affiliates to enable Deutsche Telekom to consolidate T-Mobile into Deutsche Telekom’s financial statements. Pursuant to the SoftBank Proxy Agreement, at any meeting of the stockholders of the Company, the shares of common stock beneficially owned by SoftBank will be voted in the manner directed by Deutsche Telekom, which obligation will terminate upon the earliest of: (i) with respect to each such share of common stock, the date on which such share is transferred to a third party in accordance with the terms of the SoftBank Proxy Agreement, subject to certain exceptions, (ii) the date on which Deutsche Telekom owns 55% or more of the outstanding T-Mobile Voting Securities and (iii) the date on which Deutsche Telekom has transferred an aggregate number of shares representing 5% or more of the outstanding common stock as of immediately following the effective time of the merger of a wholly owned subsidiary of T-Mobile with and into Sprint pursuant to the terms of the Business Combination Agreement (the “Effective Time”). The SoftBank Proxy Agreement also contains certain restrictions on the ability of each of SoftBank and Deutsche Telekom to transfer or acquire shares of our common stock, including that each of SoftBank and Deutsche Telekom is not permitted to transfer its shares without the prior written consent of the other stockholder from and after the Effective Time until the fourth anniversary of the Effective Time, subject to certain exceptions, including for transfers of up to 5% of the common stock outstanding as of the Effective Time beginning after the first anniversary of the Effective Time and up to an additional 10% of the common stock outstanding as of the Effective Time beginning after the second anniversary of the Effective Time. Deutsche Telekom and SoftBank have also agreed to further limitations upon the ability of SoftBank to transfer shares of our common stock.

The Claure Proxy Agreement establishes among Deutsche Telekom, CM LLC and Marcelo Claure certain rights and obligations in respect of the shares of common stock owned by CM LLC and certain of its affiliates, including Marcelo Claure, to enable Deutsche Telekom to consolidate T-Mobile into Deutsche Telekom’s financial statements. Pursuant to the Claure Proxy Agreement, at any meeting of the stockholders of the Company, the shares of common stock beneficially owned by CM LLC will be voted in the manner directed by Deutsche Telekom, which obligation will terminate upon the earliest of: (i) with respect to each such share of common stock, the date on which such share is transferred to a third party in accordance with the terms of the Proxy Agreement, subject to certain exceptions, (ii) the date on which Deutsche Telekom owns 55% or more of the outstanding T-Mobile Voting Securities and (iii) the date on which Deutsche Telekom has transferred an aggregate number of shares representing 5% or more of the outstanding common stock as of June 22, 2020. The Claure Proxy Agreement also contains certain restrictions on the ability of CM LLC and other entities related to Mr. Claure to transfer or acquire shares of our common stock, including a prohibition on transfer of shares without the prior written consent of Deutsche Telekom until April 1, 2024, subject to certain exceptions.

As a result of the Proxy Agreements, we are a “controlled company” for purposes of the rules of The NASDAQ Stock Market LLC (“NASDAQ”), which provides us with exemptions from certain corporate governance requirements under NASDAQ rules.

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, (iii) for willful or negligent payment of unlawful dividends, or (iv) 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.

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 or proceeding brought on behalf of the Company, (ii) any action asserting a claim of breach of a fiduciary duty owed by any director, officer or employee of the Company to the Company or its stockholders, (iii) any action asserting a claim arising pursuant to any provision of the General Corporation Law of the State of Delaware (the “DGCL”), the Certificate of Incorporation or the Company’s Bylaws or (iv) any other action asserting a claim arising under, in connection with, and governed by the internal affairs doctrine. This choice of forum provision does not waive our compliance with our obligations under the federal securities laws and the rules and regulations thereunder. Moreover, the provision does not apply to suits brought to enforce a duty or liability created by the Exchange Act or by the Securities Act.

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 NASDAQ Global Select Market under the symbol “TMUS.”

Transfer Agent and Registrar

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

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

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 the applicable provisions of the Exchange Act, and the rules and regulations under the Exchange Act, including, without limitation, 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 shares of common stock to engage in market-making activities with respect to the particular shares of common stock being distributed. All of the above may affect the marketability of the common stock and the ability of any person or entity to engage in market-making activities with respect to the shares of 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.
