T-Mobile USA, Inc., a Delaware corporation (“T-Mobile USA” or the “Issuer”) and a direct wholly-owned subsidiary of T-Mobile US, Inc. (“T-Mobile US” or “Parent”), hereby offers to exchange, upon the terms and conditions set forth in this prospectus and the accompanying letter of transmittal, up to $500,000,000 in aggregate principal amount of its 2.400% Senior Secured Notes due 2029 (the “2029 Exchange Notes”), $1,000,000,000 in aggregate principal amount of its 2.700% Senior Secured Notes due 2032 (the “2032 Exchange Notes”), $2,800,000,000 in aggregate principal amount of its 3.400% Senior Secured Notes due 2052 (the “2052 Exchange Notes”), and $700,000,000 in aggregate principal amount of its 3.600% Senior Secured Notes due 2060 (the “2060 Exchange Notes” and, together with the 2029 Exchange Notes, the 2032 Exchange Notes and the 2052 Exchange Notes, the “Exchange Notes”) for an equal amount of its outstanding 2.400% Senior Secured Notes due 2029 (the “2029 Original Notes”), 2.700% Senior Secured Notes due 2032 (the “2032 Original Notes”), 3.400% Senior Secured Notes due 2052 (the “2052 Original Notes”), and 3.600% Senior Secured Notes due 2060 (the “2060 Original Notes” and together with the 2029 Original Notes, the 2032 Original Notes and the 2052 Original Notes, the “Original Notes”). We refer to the Original Notes and the Exchange Notes, collectively, as the “Notes.”

The Issuer’s obligations under the Original Notes are, and under the Exchange Notes will be, guaranteed (such guarantees, the “Guarantees”) by T-Mobile US and each wholly-owned subsidiary of the Issuer that is not an Excluded Subsidiary and is or becomes an obligor of the Credit Agreement (as defined herein) or issues or guarantees certain capital markets debt securities, other than certain Excluded Subsidiaries that do not guarantee the Original Notes and will not guarantee the Exchange Notes, and any future direct or indirect subsidiary of T-Mobile US or any subsidiary thereof that owns capital stock of the Issuer. The Guarantees are provided (in the case of the Original Notes) and will be provided (in the case of the Exchange Notes) on a senior secured basis except for the Unsecured Guarantees of Sprint LLC (formerly known as Sprint Corporation), Sprint Communications LLC (formerly known as Sprint Communications, Inc.) and Sprint Capital Corporation (the “Unsecured Guarantors”), which are provided (in the case of the Original Notes) and will be provided (in the case of Exchange Notes) on a senior unsecured basis (the “Unsecured Guarantees”).

The Original Notes and the Guarantees thereof are, and the Exchange Notes and the Guarantees thereof will be, the Issuer’s and the guarantors’ unsubordinated obligations; secured (except for the Unsecured Guarantees) by a first priority security interest, subject to permitted liens, in substantially all of the Issuer’s and such guarantors’ present and future assets other than Excluded Assets (as defined herein) on an equal and ratable basis with the obligations under the Credit Agreement and obligations under any other existing and future permitted first priority secured obligations; senior in right of payment to any future indebtedness of the Issuer or any guarantor to the extent that such future indebtedness provides by its terms that it is subordinated in right of payment to the Notes and the Guarantees; effectively senior to all existing and future unsecured indebtedness of the Issuer or any guarantor (other than the Unsecured Guarantors) and any future indebtedness of the Issuer or any guarantor (other than the Unsecured Guarantors) secured by a junior lien on the collateral, in each case to the extent of the value of the collateral securing the obligations under the Notes; equal in right of payment with any of the Issuer’s and the guarantors’ existing and future indebtedness and other liabilities that are not by their terms subordinated in right of payment to the Notes, including, without limitation, obligations under the Credit Agreement, the Existing T-Mobile Unsecured Notes (as defined herein) and the Existing Sprint Unsecured Notes (as defined herein); and structurally subordinated to all of the liabilities and other obligations of the subsidiaries of T-Mobile US that are not obligors with respect to the Notes, including the Existing Sprint Spectrum-Backed Notes (as defined herein), factoring arrangements and tower obligations. Assets excluded from the collateral securing the Notes will include, among other things, Permitted Receivables Financing Assets (as defined herein). In addition, the Sprint Spectrum Portfolio (as defined herein) securing the Existing Sprint Spectrum-Backed Notes is pledged to secure such indebtedness and does not secure the Original Notes and will not secure the Exchange Notes.

The terms of the Exchange Notes are substantially identical to the terms of the Original Notes, except that the Exchange Notes will generally be freely transferable and do not contain certain terms with respect to registration rights and additional interest. The Exchange Notes will be issued under the indentures governing the Original Notes. For a description of the principal terms of the Exchange Notes, see “Description of Notes.”

The 2060 Original Notes were an additional issuance of the 3.600% Senior Secured Notes due 2060 issued by the Issuer in an aggregate principal amount of $1,000,000,000 on October 28, 2020, which were subsequently exchanged for notes having substantially identical terms, except that such exchange notes generally are freely transferable and do not contain certain terms with respect to registration rights and additional interest (the “Existing Registered 2060 Notes”). The 2060 Original Notes are consolidated with and form a single series with the Existing Registered 2060 Notes and have the same respective terms other than the settlement date, offering price, initial interest payment date and registration rights. However, the 2060 Original Notes are not fungible with the Existing Registered 2060 Notes, and unless and until exchanged for 2060 Exchange Notes pursuant to this exchange offer, the 2060 Original Notes will have separate CUSIP numbers from, and will not be fungible with, the Existing Registered 2060 Notes.

The exchange offer will expire at 5:00 p.m., New York City time, on     , 2022, unless we extend the offer. At any time prior to the expiration time, you may withdraw your tender of any Original Notes; otherwise, such tender is irrevocable. We will receive no cash proceeds from the exchange offer.

The Exchange Notes constitute new issues of securities for which there is no established trading market. Any Original Notes not tendered and accepted in the exchange offer will remain outstanding. To the extent Original Notes are tendered and accepted in the exchange offer, your ability to sell untendered, and tendered but unaccepted, Original Notes could be adversely affected. Following consummation of the exchange offer, the Original Notes will continue to be subject to their existing transfer restrictions and we will generally have no further obligations to provide for the registration of the Original Notes under the Securities Act. We cannot guarantee that an active trading market will develop or give assurances as to the liquidity of the trading market for either the Original Notes or the Exchange Notes. We do not intend to apply for listing of either the Original Notes or the Exchange Notes on any exchange or market.

Each broker-dealer that receives Exchange Notes for its own account pursuant to the exchange offer must acknowledge that it will deliver a prospectus meeting the requirements of the Securities Act (or, to the extent permitted by law, make available a prospectus meeting the requirements of the Securities Act to purchasers) in connection with any resale of such Exchange Notes. The letter of transmittal states that by so acknowledging and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an “underwriter” within the meaning of the Securities Act. This prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of the Exchange Notes received in exchange for the Original Notes where such Original Notes were acquired by such broker-dealer as a result of market-making or other trading activities. We have agreed that, for a period of 90 days following the effective date of the registration statement of which this prospectus forms a part, we will make this prospectus available to any broker-dealer for use in connection with any such resale. See “Plan of Distribution.”

This prospectus and the letter of transmittal are first being mailed to all holders of the Original Notes on or about    , 2022.

Certain statements in this prospectus, the documents incorporated by reference and our other public statements include “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. All statements, other than statements of historical fact, including information concerning our future results of operations, are forward-looking statements. These forward-looking statements are generally identified by the words “anticipate,” “believe,” “estimate,” “expect,” “intend,” “may,” “could” or similar expressions. Forward-looking statements are based on current expectations and assumptions, which are subject to risks and uncertainties that may cause actual results to differ materially from the forward-looking statements. The following important factors, along with the risk factors identified under “Risk Factors” and the risk factors incorporated by reference herein, could affect future results and cause those results to differ materially from those expressed in the forward-looking statements:

Additional information concerning these and other risk factors is contained in the section titled “Risk Factors” in this prospectus and the documents incorporated herein by reference.

Forward-looking statements in this prospectus or the documents incorporated by reference speak only as of the date of this prospectus or the applicable document incorporated by reference (or such earlier date as may be specified in the applicable document), as applicable, are based on assumptions and expectations as of such dates, and involve risks, uncertainties and assumptions, many of which are beyond our ability to control or predict, including the factors above. Given these risks and uncertainties, readers are cautioned not to place undue reliance on such forward-looking statements. We undertake no obligation to revise or publicly release the results of any revision to these forward-looking statements, except as required by law. For more information, see the section entitled “Where You Can Find More Information.” The results presented for any period may not be reflective of results for any subsequent period.

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

Prior to making a decision to participate in the exchange offer, you should carefully consider the risks described below, as well as the risks and other information contained or incorporated by reference in this prospectus, including the “Risk Factors” in Parent’s Annual Report on Form 10-K for the year ended December 31, 2021, filed on February 11, 2022 and Parent’s Quarterly Report on Form 10-Q for the quarter ended March 31, 2022, filed on May 6, 2022. If any of the risks described in this prospectus, or the risks described in any documents incorporated by reference in this 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.

We will issue Exchange Notes pursuant to the exchange offer only after a timely receipt of your Original Notes, a properly completed and duly executed letter of transmittal and all other required documents. Therefore, if you want to tender your Original Notes, please allow sufficient time to ensure timely delivery. If we do not receive your Original Notes, letter of transmittal and other required documents by the expiration time of the exchange offer, we will not accept your Original Notes for exchange. We are generally under no duty to give notification of defects or irregularities with respect to the tenders of Original Notes for exchange. If there are defects or irregularities with respect to your tender of Original Notes, we may not accept your Original Notes for exchange.

We did not register the Original Notes and do not intend to do so following the exchange offer. Original Notes that are not tendered will therefore continue to be subject to the existing transfer restrictions and may be transferred only in limited circumstances under applicable securities laws. Because we anticipate that most holders of the Original Notes will elect to exchange their Original Notes for Exchange Notes due to the absence of restrictions on the resale of Exchange Notes under the Securities Act, we anticipate that the liquidity of the market for any Original Notes remaining after the completion of this exchange offer may be substantially limited. If you do not exchange your Original Notes, you will lose your right, except in limited circumstances, to have your Original Notes registered under the federal securities laws. As a result, if you hold Original Notes after the exchange offer, you may be unable to sell your Original Notes and the value of the Original Notes may decline. We have no obligation, except in limited circumstances, and do not currently intend, to file an additional registration statement to cover the resale of Original Notes that did not tender in the exchange offer or to re-offer to exchange the Exchange Notes for Original Notes following the expiration of the exchange offer.

Based on interpretations of the staff of the SEC contained in Exxon Capital Holdings Corp., SEC no-action letter (April 13, 1988), Morgan Stanley & Co. Inc., SEC no-action letter (June 5, 1991) and Shearman & Sterling, SEC no-action letter (July 2, 1983), we believe that you may offer for resale, resell or otherwise transfer the Exchange Notes without compliance with the registration and prospectus delivery requirements of the Securities Act. However, in some instances described in this prospectus under “Plan of Distribution,” you will remain obligated to comply with the registration and prospectus delivery requirements of the Securities Act to transfer your Exchange Notes. In these cases, if you transfer any Exchange Note without delivering a prospectus meeting the requirements of the Securities Act or without an exemption from registration of your Exchange Notes under the Securities Act, you may incur liability under the Securities Act. We do not and will not assume, or indemnify you against, this liability.

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:

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 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.

Although we have substantial indebtedness, we may still be able to incur significantly more debt, including more 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 our subsidiaries, subject to specified limitations. In particular, as of March 31, 2022, we had $5.5 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.”

The Unsecured Guarantees will be general unsecured, unsubordinated obligations ranking effectively junior in right of payment to all existing and future secured debt of the Unsecured Guarantors, to the extent of the value of the collateral securing such debt. If an Unsecured Guarantor is declared bankrupt, becomes insolvent or is liquidated or reorganized, any secured debt of that Unsecured Guarantor will be entitled to be paid in full from the assets of the Unsecured Guarantor securing that debt before any payment may be made with respect to the Guarantees of such Unsecured Guarantor.

Holders of the Notes will participate ratably in any remaining assets with all other holders of the Unsecured 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 Unsecured Guarantors. It is possible that with respect to the Unsecured Guarantees, there will be no assets from which claims of holders of the Notes can be satisfied.

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 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 do not provide guarantees of the Original Notes and will not provide guarantees of the Notes. See “—The value of the Collateral securing the Notes and the related guarantees may not be sufficient to satisfy our and the guarantors’ obligations under the Notes” and “Description of Notes—Brief Description of the Notes and the Note Guarantees—The Note Guarantees.”

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 and the other Existing T-Mobile Secured 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 the Revolving Credit Facility under our Credit Agreement, we will need to maintain certain financial ratios on a quarterly basis. 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 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 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 expect to 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.

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 Original Notes, the other Existing T-Mobile Secured Notes, the Existing T-Mobile Unsecured Notes, the Existing Sprint Spectrum-Backed Notes and certain of the Existing Sprint Unsecured Notes provide, and the indentures governing the Exchange Notes will 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 Unsecured Notes, all outstanding Existing Sprint Spectrum-Backed Notes, the applicable Existing Sprint Unsecured Notes and all outstanding Notes and other Existing T-Mobile Secured 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 Notes—Repurchase at the Option of Holders—Change of Control Triggering Event” and “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 Notes, the other Existing T-Mobile Secured Notes, the Existing T-Mobile Unsecured 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, the Notes and such other obligations generally would be permitted to remain outstanding in accordance with their terms.

The failure to purchase the Notes, the other Existing T-Mobile Secured Notes, the Existing T-Mobile Unsecured 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 Exchange Notes. Any such event of default would likely trigger an event of default on other outstanding or future indebtedness.

The indentures governing the Original Notes, the other Existing T-Mobile Secured Notes, the Existing T-Mobile Unsecured Notes and the Existing Sprint Unsecured Notes, the Credit Agreement and other financing arrangements, impose, and the indentures governing the Exchange Notes will impose, significant operating and financial restrictions on us. These restrictions, subject in certain cases to customary baskets, exceptions and incurrence-based ratio tests, limit our and our subsidiaries’ ability to engage in some transactions. In particular, the Credit Agreement and the indentures governing the Existing T-Mobile Unsecured Notes include restrictions limiting our and our subsidiaries’ ability to:

In addition, the indentures governing the Original Notes, the other Existing T-Mobile Secured Notes, the Existing T-Mobile Unsecured Notes and Existing Sprint Unsecured Notes and the Credit Agreement limit, and the indentures governing the Exchange Notes will limit, our and our subsidiaries’ ability to:

In addition, the Revolving Credit Facility contains a financial maintenance covenant, requiring us to maintain a total first lien net leverage ratio at the end of each fiscal quarter of 3.30:1.00 or less. Any future debt that we incur may contain financial maintenance covenants as well. These restrictions could limit our ability to obtain debt financing, repurchase stock, refinance or pay principal on our outstanding debt, complete acquisitions for cash or debt or react to changes in our operating environment or the economy.

Any failure to comply with the restrictions of the indentures governing the Notes, the other Existing T-Mobile Secured 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 agreements 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 and to require us to repay all amounts then outstanding. Any of these events would have a material adverse effect on our business, financial condition and operating results.

The rights of the holders of the Notes with respect to the Collateral will be subject to a collateral trust and intercreditor agreement among all holders of obligations secured by the Collateral, including the obligations under the Notes, the other Existing T-Mobile Secured Notes and the Credit Agreement, up to $3.5 billion of lease payment obligations under the Existing Sprint Spectrum Lease, the obligations under the Designated L/C Facilities (as defined under “Description of Notes—Certain Definitions”) and any other permitted first priority secured obligations, as well as any future holders of permitted obligations secured by a junior lien on the Collateral (the “Intercreditor Agreement”). Pursuant to the terms of the Intercreditor Agreement, all matters related to the Collateral securing the Notes will be at the exclusive direction of the controlling party. The controlling party will be (a) at any time when any first priority secured obligations or commitments in respect thereof have not been paid in full, (i) the First Priority Agent (as defined under “Description of Notes—Certain Definitions”) or (ii) if (1) an acceleration notice has been delivered (and remains in effect) in respect of any Material First Priority Secured Obligations (as defined under “Description of Notes—Certain Definitions”) and (2) both (x) the first priority secured obligations in respect of which the First Priority Agent is the holder representative have not been accelerated (or subject to a termination event, as the case may be) and (y) the First Priority Agent has not commenced (or instructed the Collateral Trustee to commence) and is not diligently pursuing (or has not instructed the Collateral Trustee to diligently pursue) any collateral enforcement action with respect to a material portion of any Collateral within 180 consecutive days since the delivery of such acceleration notice, the holder representative for the series of obligations constituting the then highest outstanding amount of Material First Priority Secured Obligations in respect of which an acceleration notice has been delivered, provided that upon the acceleration of (or the occurrence of a termination event in respect of) the first priority secured obligations in respect of which the First Priority Agent is the holder representative or upon the commencement by the First Priority Agent (or the Collateral Trustee upon instruction of the First Priority Agent) of any collateral enforcement action with respect to a material portion of any Collateral, the First Priority Agent shall become the controlling party, or (iii) if (1) an acceleration notice has been delivered (and remains in effect) in respect of any Material Junior Priority Secured Obligations (as defined under “Description of Notes—Certain Definitions”) and (2) both (x) no series of Material First Priority Secured Obligations has been accelerated (or subject to a termination event, as the case may be) and (y) no holder representative of any Material First Priority Secured Obligations has commenced (or instructed the Collateral Trustee to diligently pursue) any collateral enforcement action with respect to a material portion of any Collateral within 270 consecutive days since the delivery of such acceleration notice, the Junior Priority Agent (as defined under “Description of Notes—Certain Definitions”); provided that upon the acceleration of (or the occurrence of a termination event in respect of) any Material First Priority Secured Obligations or upon the commencement by any holder representative in respect of any series of Material First Priority Secured Obligations (or the Collateral Trustee upon instruction of such holder representative) of any collateral enforcement action with respect to a material portion of the Collateral, such holder representative shall become the controlling party in accordance with the terms of clause (a) above and (b) at any time when all first priority secured obligations or commitments in respect thereof have been paid in full and any junior priority secured obligations or commitments in respect thereof remain outstanding, the Junior Priority Agent. The First Priority Agent will be (a)(i) initially, the administrative agent under the Credit Agreement and (ii) to the extent there are two or more syndicated credit agreements outstanding that are secured by the Collateral on a first-priority basis, the agent designated (if different and so designated) in writing by T-Mobile and representing the highest outstanding amount of such syndicated credit agreements secured by the Collateral on a first-priority basis; and (b) at any time when the aggregate outstanding amount and unfunded commitments under the syndicated credit agreements referenced in clause (a)(ii) above is less than $1.0 billion, (x) the agent or trustee designated as “First Priority Agent” by the Majority First Priority Secured Parties (as defined under “Description of Notes—Certain Definitions”) (or their holder representatives) or (y) in the event the Majority First Priority Secured Parties have not designated a First Priority Agent, then the representative for the series of obligations constituting the then highest outstanding amount of first priority secured obligations (see “Description of Notes—The Collateral Trust and Intercreditor Agreement”). The controlling party may, in connection with an enforcement action, dispose of, release, or foreclose on, or take other actions with respect to, the Collateral (including amendments of and waivers under the security documents) with which holders of the Notes may disagree or that may be contrary to the interests of holders of the Notes, even after a default under the Notes. To the extent Collateral is released from the lien securing the obligations under the Credit Agreement (or any other obligations, the representative of which is the controlling party) in connection with foreclosure or enforcement action, even if a default under the Notes exists, liens on the same Collateral securing the Notes will also be released. In addition, the Intercreditor Agreement generally provides that the Collateral Trustee

may change, waive, modify or vary the security documents governing such liens without the consent of the holders of the Notes (except under certain limited circumstances) and that the security documents governing the liens securing the Notes will be automatically changed, waived and modified in the same manner (subject to certain limitations and exceptions).

The Notes will be secured by a first priority lien, subject to certain exceptions and permitted liens, on the Collateral described in this prospectus. The Collateral secures a total of $36.8 billion under the Notes and the other Existing T-Mobile Secured Notes, as well as obligations under any other existing and future permitted first priority secured obligations. The amount of future indebtedness permitted to rank pari passu with the Notes on the Collateral is substantial. Your rights to the Collateral would be diluted by any additional indebtedness or other obligations that are secured by the Collateral.

The Existing Sprint Spectrum Note Entities own a separate pool of 2.5 GHz and 1.9 GHz spectrum which has been pledged to secure indebtedness under the Sprint Spectrum Note Facility. This spectrum will not secure the Notes or any other permitted first priority secured obligations. Spectrum lease payments from a Sprint subsidiary, Sprint Communications, are used to service the indebtedness under the Existing Sprint Spectrum-Backed Notes. This lease payment obligation is secured by a first priority security interest in the Collateral (with such security capped at $3.5 billion), shared with the Notes, the other Existing T-Mobile Secured Notes and other permitted first priority secured obligations.

No appraisal of the value of the Collateral that will secure the Notes has been made in connection with this exchange offer. The value of the Collateral at any time will depend on market and other economic conditions, including the availability of suitable buyers. By their nature, some or all of the pledged assets may be illiquid and may have no readily ascertainable market value. We cannot assure you that the fair market value of the Collateral as of the date of this prospectus equals or exceeds the principal amount of the debt secured thereby. The value of the assets pledged as Collateral for the Notes could be impaired in the future as a result of changing economic conditions, our failure to implement our business strategy, competition, unforeseen liabilities and other future events. Accordingly, liquidating the Collateral may not result in proceeds in an amount sufficient to pay all or any of the amounts due on the Notes, the amounts due on the other Existing T-Mobile Secured Notes, the obligations under the Credit Agreement and any other permitted first priority secured obligations that we may incur. If the proceeds of any sale of Collateral are not sufficient to pay all amounts due on the Notes and all such other permitted first priority secured obligations, the holders of the Notes would have an unsecured claim against our and the Subsidiary Guarantor’s remaining assets.

The security interest in the Collateral will be subject to practical problems generally associated with the realization of security interests in collateral. For example, the Collateral Trustee may need to obtain the consent of a third party to obtain or enforce a security interest in a contract. We cannot assure you that the consents of any third parties will be given when required to facilitate a foreclosure on any assets. See in particular “—It may be difficult to realize the value of the FCC license rights pledged to secure the Notes” below. Accordingly, the Collateral Trustee may not be able to foreclose upon such assets, effectively eliminating the security provided by the applicable Collateral.

Applicable law provides that security interests in certain property and rights acquired after the grant of a general security interest can only be perfected through certain actions undertaken by the secured party once such property and rights are acquired and identified. The Trustee (as defined under “Description of Notes—General”) or the Collateral Trustee may not monitor, or we may not inform the Trustee or the Collateral Trustee of, the future acquisitions of property and rights that constitute Collateral, and the liens on such Collateral may not be perfected if the Collateral Trustee does not or is not able to take the actions necessary to perfect the liens. Neither the Trustee nor the Collateral Trustee has any obligation to monitor the acquisition of additional property or rights that constitute Collateral or the perfection of any security interest in favor of the Collateral Trustee against third parties. Such failure may result in the loss of the security interest in the applicable Collateral or loss of priority of the security interest in favor of the Collateral Trustee, as applicable, against third parties. Further, even if liens on Collateral acquired in the

future are properly perfected, such liens may potentially be avoidable as a preference in any bankruptcy proceeding under certain circumstances. See “—Any future pledge of Collateral or guarantee provided after the Notes are issued might be avoided in a bankruptcy.”

Certain material assets are excluded from the Collateral, as described under “Description of Notes—Collateral—Excluded Assets.” Excluded Assets will include assets transferred to or held by a Permitted Tower Financing Subsidiary (as defined herein), Permitted Receivables Financing Assets and any assets of Sprint or any subsidiary of Sprint, to the extent that the granting, or continuation, of any lien or security interest thereon would, in the reasonable determination of the Issuer, require the Existing Sprint Unsecured Notes or the Existing T-Mobile Unsecured Notes issued by any Unsecured Guarantor to be secured on an equal and ratable basis. Collateral securing the Notes will be released, without your consent or the consent of the Trustee or the Collateral Trustee, to the extent that the property constituting such collateral becomes an Excluded Asset. Permitted Receivables Financing Assets include financial assets that are or may be used from time to time for other financings. As of March 31, 2022, we had approximately $11.9 billion in Permitted Receivables Financing Assets. In addition, the Existing Sprint Spectrum Note Entities own a separate pool of 2.5 GHz and 1.9 GHz spectrum, which we refer to as the Sprint Spectrum Portfolio and which has been pledged to secure indebtedness under the Sprint Spectrum Note Facility. This spectrum will not secure the Notes or any other permitted first priority secured obligations. Further, no assets of any of our non-guarantor subsidiaries will constitute Collateral.

Telecommunication license rights constitute a significant part of the Collateral that currently secures the Original Notes and will initially secure the Exchange Notes and in each case the related Guarantees. The ability of the Collateral Trustee to foreclose on such Collateral on behalf of the holders of the Notes may be subject to prior approval by the FCC and other governmental authorities. In particular, the Collateral Trustee will not be legally permitted to exercise any rights with respect to the FCC license rights upon the occurrence of an event of default if such action would constitute or result in any assignment of any FCC license or any other form of change of control (whether as a matter of law or fact) of the entity holding any FCC license unless any necessary prior approval of the FCC is obtained. There can be no assurance that any such required approval can be obtained on a timely basis or at all. This requirement may limit the number of potential bidders for the FCC license rights in any foreclosure and may delay the sale process, either of which events may have a material adverse effect on the sale price of the FCC license rights. Further, certain of the FCC license rights are already collateralized under the Sprint Spectrum Note Facility, and the ability to realize the value of the FCC license rights will be subordinated to such collateral claims. Therefore, the practical value of realizing on the FCC license rights may be limited.

The Collateral securing the obligations under the Exchange Notes includes the Spectrum SPV Equity Interests (as defined under “Description of Notes—Certain Definitions”), which are equity interests in certain intermediate holding companies employed in the Sprint Spectrum Note Facility. The change in ownership resulting from a foreclosure upon these pledged equity interests would constitute an event of default under the indenture governing the Sprint Spectrum Note Facility. Such an event of default would permit the immediate acceleration of obligations under the Existing Sprint Spectrum-Backed Notes. The holders of the Existing Sprint Spectrum-Backed Notes would have debt claims against the obligors under the Existing Sprint Spectrum Note Facility (the “Existing Sprint Spectrum Securitization Obligors”) that would be structurally senior to the residual equity claims of holders of the Notes. Consequently, the holders of Existing Sprint Spectrum-Backed Notes would be entitled to be paid in full from the assets of the Existing Sprint Spectrum Securitization Obligors before any payment may be made to the holders of the Notes on account of a foreclosure upon the Spectrum SPV Equity Interests.

The security documents allow us to remain in possession of, retain exclusive control over, freely operate, and collect, invest and dispose of any income from, the Collateral. For example, so long as no default or event of default under the indentures governing the Notes and the other Existing T-Mobile Secured Notes, the Credit Agreement or

the Existing Sprint Spectrum Lease would result therefrom, we may, among other things, without any release or consent by the Trustee or the Collateral Trustee, conduct ordinary course activities with respect to Collateral, such as selling, factoring, abandoning or otherwise disposing of Collateral and making ordinary course cash payments (including repayments of indebtedness). To the extent we sell any assets that constitute such Collateral, the proceeds of such sale will be subject to the liens securing the Notes only to the extent such proceeds constitute Collateral under the security documents. Such proceeds will also be subject to any security interests of creditors other than the holders of the Notes, including the other holders of obligations secured by the Collateral on a first-priority basis. To the extent the proceeds of any sale of Collateral do not constitute Collateral under the security documents, the pool of assets securing the Notes will be reduced.

There are circumstances other than repayment or discharge of the Notes under which Collateral securing the Notes will be released automatically, without your consent or the consent of the Trustee or the Collateral Trustee, including:

Applicable law provides that a security interest in certain tangible and intangible assets can only be properly perfected and its priority retained through certain actions undertaken by the secured party. To the extent a security interest in certain Collateral is granted or perfected after the date which is 30 days following the completion of an offering, that security interest would remain at risk of being avoided as a preferential transfer by the pledgor, as debtor in possession, or by its trustee in bankruptcy, if we or any guarantor were to file for bankruptcy within 90 days after the grant or after perfection (or, under certain circumstances, a longer period). See “—Any future pledge of Collateral or guarantee provided after the Notes are issued might be avoided in a bankruptcy.” In addition, the security documents in connection with the Notes do not require us to take a number of actions related to the perfection or priority of the liens on certain Collateral in favor of the Collateral Trustee for the benefit of the holders of the Notes. As a result of these limitations, the security interest in favor of the Collateral Trustee for the benefit of the holders of the Notes may not be perfected or enforceable (or may be subject to other liens) under applicable law with respect to a portion of the Collateral.

The Collateral securing the Notes may be subject to other liens permitted under the indentures governing the Notes, whether arising prior to, on or after the date the Notes are issued. The existence of any permitted liens could materially adversely affect the value of the Collateral that could be realized by the holders of the Notes as well as the ability of the Collateral Trustee to realize or foreclose on such Collateral. In addition, the imposition of certain permitted liens would cause the relevant assets to become “Excluded Assets,” which will not secure the Notes or the Guarantees. See “Description of Notes—Collateral—Excluded Assets.”

The Existing Sprint Spectrum Note Entities own a separate pool of 2.5 GHz and 1.9 GHz spectrum which has been pledged to secure indebtedness under the Sprint Spectrum Note Facility. The Sprint Spectrum Portfolio will not secure the Notes or any other permitted first priority secured obligations. Spectrum lease payments from a Sprint

subsidiary, Sprint Communications, are used to service the indebtedness under the Existing Sprint Spectrum-Backed Notes. This lease payment obligation will be secured by a first priority security interest in the Collateral (with such security capped at $3.5 billion), shared with the Notes, the other Existing T-Mobile Secured Notes and other permitted first priority secured obligations.

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

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 (and the related security interests) 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) or granted the related security interest, such guarantor:

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 and the related security interests) 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 (and the related security interest):

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 (or the related security interest) 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 (and the related security interests), subordinate them to the applicable guarantor’s other debt or take other action detrimental to the holders of the Notes.

If a Guarantee (and the related security interest) 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 (or the benefit of the related security interest) and will only be our creditor or that of any guarantor whose obligation was not set aside or found to be unenforceable. In addition, the loss of a Guarantee generally will constitute an event of default under the indentures governing the Notes, the other Existing T-Mobile Secured 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 indentures governing the Notes and the related security documents will require us to grant liens on certain assets that we or any guarantor acquire. Any future guarantee or additional lien in favor of the Collateral Trustee for the benefit of the holders of the Notes might be avoidable by the grantor (as debtor-in possession) or by its trustee in bankruptcy or other third parties (including potentially our other creditors) if certain events or circumstances exist or occur. For instance, if the entity granting a future guarantee or additional lien was insolvent at the time of the grant and if such grant was made within 90 days before that entity commenced a bankruptcy proceeding (or one year before commencement of a bankruptcy proceeding if the creditor that benefited from the guarantee or lien is deemed an “insider” under the U.S. Bankruptcy Code), and the granting of the future guarantee or additional lien enabled the holders of the Notes to receive more than they would if the grantor were liquidated under a hypothetical case under chapter 7 of the U.S. Bankruptcy Code, then such guarantee or lien could be avoided as a preferential transfer. Liens recorded or perfected after the completion of the exchange offer may be treated under bankruptcy law as if they were delivered to secure previously existing indebtedness. Accordingly, if we or any guarantor were to become subject to a bankruptcy proceeding, any mortgage or security interest in other Collateral delivered after the completion of the exchange offer would face a greater risk than security interests in place as of the completion of the exchange offer of being avoided as a preference under bankruptcy law. To the extent that the grant of any such mortgage or other security interest or guarantee is avoided as a preference, the holders of the Notes would lose the benefit of the security that the Collateral was intended to provide or the benefit of such guarantee (as applicable).

The right of the Collateral Trustee to foreclose upon, repossess and dispose of the Collateral upon acceleration is likely to be significantly impaired (or at a minimum delayed) by federal bankruptcy law if bankruptcy proceedings are commenced by or against us before or possibly even after the Collateral Trustee has repossessed and disposed of Collateral. Under the U.S. Bankruptcy Code, pursuant to the automatic stay imposed upon a bankruptcy filing, a secured creditor, such as the Collateral Trustee, is prohibited from foreclosing upon or repossessing its security from a debtor in a bankruptcy case, or from disposing of security repossessed from a debtor, without prior bankruptcy court approval (which may not be given under the circumstances). Moreover, bankruptcy law permits the debtor to continue to retain and to use collateral, and the proceeds, products, rents or profits of the collateral, even though the debtor is in default under the applicable debt instruments, provided that the secured creditor is given “adequate protection.” The meaning of the term “adequate protection” may vary according to circumstances, but it is intended in general to protect the value of the secured creditor’s interest in the collateral and may include cash payments or the granting of additional or replacement security, if and at such time as the court in its discretion determines, for any diminution in the value of the collateral as a result of the stay of repossession or disposition or any use of the collateral by the debtor during the pendency of the bankruptcy case. A bankruptcy court may determine that a secured creditor may not require compensation for a diminution in the value of its collateral if the value of the collateral exceeds all of the debt it secures. In view of the lack of a precise definition of the term “adequate protection” and the broad discretionary powers of a bankruptcy court, it is impossible to predict whether any payments under the Notes could be made following commencement of or during a bankruptcy case or the length of any potential delay in making any such payments post-petition, whether or when the Collateral Trustee could foreclose upon, repossess or dispose of the Collateral, or whether or to what extent the holders of the Notes would be compensated for any delay in payment or loss of value of the Collateral through the requirements of “adequate protection.”

Furthermore, in the event the bankruptcy court determines that the value of the Collateral is not sufficient to repay all amounts due on the Notes (and all other obligations secured thereby on a senior or pari passu basis), the

holders of the Notes would have “undersecured claims” as to the difference. Federal bankruptcy laws do not permit the payment or accrual of post-petition interest, costs, fees, expenses and attorneys’ fees for “undersecured claims” during the debtor’s bankruptcy case. Other consequences of a finding of under-collateralization would include, among other things, a lack of entitlement to receive “adequate protection^” under federal bankruptcy laws with respect to the unsecured portion of the Notes. In addition, if any payments of post-petition interest had been made at the time of such a finding of under collateralization, those payments could be recharacterized by the bankruptcy court as a reduction of the principal amount of the Notes.

The Intercreditor Agreement also contains provisions restricting the holders of the Notes from filing certain objections in any future bankruptcy to, among other things, a proposed debtor-in-possession financing that satisfies various terms and conditions.

As a result of the foregoing, bankruptcy laws may, among other things, act to limit the ability of the holders of the Notes to realize upon the Collateral and to receive post-bankruptcy interest, fees, expenses or “adequate protection” with respect to 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 guarantor (except, in each case, by or as a result of payment under such guarantee or direct obligation), in which case any liens on the assets of such subsidiary in favor of the Collateral Trustee for the benefit of lenders under the Credit Agreement and the holders of the Notes will also be released. 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.

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 exchange offer, or the perception that such sales could occur. These sales, or the possibility that these sales may occur, also might make it more difficult for the Issuer to sell other debt securities in the future at a time and on terms that it deems appropriate.

After giving effect to the Q2 Repayment, as of March 31, 2022, we would have had outstanding approximately $70.0 billion in aggregate principal amount of debt securities, maturing in 2022 through 2060, $40.2 billion of which would be senior secured debt securities and $29.8 billion of which would be senior unsecured debt securities. Deutsche Telekom, which currently controls approximately 51.8% 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.

An active trading market may not exist for the Exchange Notes or any Original Notes that remain outstanding after the exchange offer. In addition, subsequent to their initial issuance, the Notes may trade at a discount from their initial offering price (or, in the case of Exchange Notes, the initial offering price of the Original Notes of the same series), 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 Exchange Notes or any Original Notes that remain outstanding after the exchange offer to be listed on any securities exchange or to arrange for the Exchange Notes or any Original Notes that remain outstanding after the exchange offer to be quoted on any quotation

system. An active trading market may not develop for the Exchange Notes or, if developed, may not continue. In addition, there may cease to be a market for the Original Notes. 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.

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.

T-Mobile US’ Certificate of Incorporation provides that, unless T-Mobile US consents 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 T-Mobile US, (ii) any action asserting a claim of breach of a fiduciary duty owed by any director, officer or employee of T-Mobile US to T-Mobile US or its stockholders, (iii) any action asserting a claim arising pursuant to any provision of the General Corporation Law of the State of Delaware, the Certificate of Incorporation or T-Mobile US’ 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 Securities Exchange Act of 1934, as amended (the “Exchange Act”) or by the Securities Act.

This choice of forum provision may increase costs to bring a claim, discourage claims or limit an investor’s ability to bring a claim in a judicial forum that the investor finds favorable for disputes with T-Mobile US or its directors, officers or employees, which may discourage such lawsuits against T-Mobile US and its directors, officers and employees, even though an action, if successful, might benefit our investors. Alternatively, if a court were to find the choice of forum provision to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such matters in other jurisdictions, which could increase our costs of litigation and adversely affect our business and financial condition.

The Original Notes and the Guarantees with respect thereto (other than the Guarantees provided by Sprint, Sprint Communications and Sprint Capital Corporation, which are unsecured) are secured by, among other things, pledges of (i) the capital stock of the Issuer and (ii) the capital stock of subsidiaries of the Issuer held by the Issuer or any Secured Guarantor; in each case other than Excluded Assets and subject to permitted liens, as further described under “Description of Notes—Collateral—Assets Pledged as Collateral.” The Exchange Notes and the Guarantees with respect thereto (other than the Guarantees provided by Sprint, Sprint Communications and Sprint Capital Corporation, which are unsecured) will be correspondingly secured. Such collateral security is provided on a pari passu basis with respect to the obligations under the Credit Agreement, up to $3.5 billion of lease payment obligations under the Existing Sprint Spectrum Lease, obligations under the Designated L/C Facilities and any other permitted first priority secured obligations, as further described under “Description of Notes—Collateral”. The Intercreditor Agreement sets forth the rights of, and relationship among, the applicable holder representatives under all existing and future parity and junior lien debt in respect of exercise of rights and remedies against the Issuer and the secured guarantors and certain other matters, as further described under “Description of Notes—The Collateral Trust and Intercreditor Agreement.”

The Issuer and the Guarantors are and will be able to incur additional indebtedness in the future which could share in the Collateral, including first priority secured obligations and obligations secured by permitted liens. In addition, if the Issuer or any Secured Guarantor acquires any property or asset of the type that constitutes Collateral and that is not an Excluded Asset, it must promptly grant a security interest upon such property as security for the Notes.

Collateral will be released automatically upon certain events including repayment or discharge of the Notes; a sale, transfer or other disposal of such Collateral in a transaction not prohibited under the indentures governing the Notes; with respect to Collateral held by a guarantor, upon the release of such guarantor from its Guarantee in a transaction not prohibited by the indentures governing the Notes; upon any release in connection with a foreclosure or exercise of remedies with respect to that Collateral directed by the lenders (or their representative) under the Credit Agreement or holders (or their representative) of other permitted first priority secured obligations during any period that such representatives control actions with respect to the Collateral pursuant to the Intercreditor Agreement; and in whole, upon an Investment Grade Event Election. See “Description of Notes—Collateral—Release.”

Upon the occurrence and during the continuance of an event of default under the indentures governing the Notes, subject to the terms of the Intercreditor Agreement, the Security Documents provide for (among other available remedies) the foreclosure upon and sale of the Collateral and the distribution of the net proceeds of any such sale to the holders of the Notes, the lenders under the Credit Agreement, the lessors under the Existing Sprint Spectrum Lease, the holders of any Designated L/C Facility Obligations and the holders of any other permitted first priority secured obligations on a pro rata basis, subject to any prior liens on the Collateral.

No trading market exists for the capital stock pledged as Collateral.

The assets, liabilities and results of operations as of and for the year ended December 31, 2021 and the three months ended March 31, 2022 of the combined affiliates whose securities are pledged as Collateral are not materially different than the corresponding amounts presented in the consolidated financial statements of Parent as of and for the year ended December 31, 2021 and the three months ended March 31, 2022, respectively.

We will not receive any cash proceeds from the issuance of the Exchange Notes. We are making this exchange offer solely to satisfy our obligations under the registration rights agreements entered into in connection with the offerings of the Original Notes. In consideration for issuing the Exchange Notes as contemplated in this prospectus, we will receive in exchange Original Notes in like principal amount, which will be cancelled, and, as such, issuing the Exchange Notes will not result in any increase in our indebtedness or be financed with new borrowings.

We entered into registration rights agreements (the “registration rights agreements”) with the initial purchasers of the Original Notes. In the registration rights agreements, we and the guarantors agreed to, at our cost:

In addition, we agreed to provide that upon the effectiveness of the exchange offer registration statement, we would promptly commence the exchange offer, whereby the Exchange Notes will be offered in exchange for surrender of the Original Notes, and that we will keep the registered exchange offer open for not less than 20 business days (or longer if required by applicable law including in accordance with the requirements of Regulation 14E under the Exchange Act) after the date notice of the registered exchange offer is first mailed, sent or given to the noteholders. For each note surrendered to the Issuer for exchange pursuant to the registered exchange offer, the holder of such note will receive an Exchange Note having a principal amount equal to that of the surrendered note.

We are offering the Exchange Notes under this prospectus in an exchange offer for the Original Notes to satisfy our obligations under the registration rights agreements. We refer to our offer to exchange the Exchange Notes for the Original Notes as the “exchange offer.”

Based on interpretations by the staff of the SEC, as described in no-action letters issued to third parties that are not related to us, including Morgan Stanley & Co., Inc. (available June 5, 1991) and Exxon Capital Holdings Corporation (available May 13, 1988), as interpreted in the SEC’s letter to Shearman & Sterling LLP (dated July 2, 1993), we believe the Exchange Notes will be freely transferable by holders other than our affiliates after the exchange offer without further registration under the Securities Act if the holder of the Exchange Notes represents to us in the exchange offer that it is acquiring the Exchange Notes in the ordinary course of its business, that it has no arrangement or understanding with any person to participate in the distribution of the Exchange Notes and that it is not our affiliate, as such terms are interpreted by the SEC; provided, however, that broker-dealers (“Participating Broker-Dealers”) receiving Exchange Notes in the exchange offer will have a prospectus delivery requirement with respect to resales of such Exchange Notes. We also believe that Participating Broker-Dealers may fulfill their prospectus delivery requirements with respect to Exchange Notes (other than a resale of an unsold allotment from the sale of the Original Notes) with this prospectus.

We have not entered into any arrangement or understanding with any person who will receive Exchange Notes in the exchange offer to distribute those securities following completion of the exchange offer. We are not aware of any person that will participate in the exchange offer with a view to distribute the Exchange Notes. If you tender your Original Notes in the exchange offer with the intention of participating in any manner in a distribution of the Exchange Notes, you:

Unless an exemption from registration is otherwise available, the resale by any security holder intending to distribute Exchange Notes should be covered by an effective registration statement under the Securities Act containing the selling security holder’s information required under the Securities Act. This prospectus may be used for an offer to resell, a resale or other retransfer of Exchange Notes only as specifically described in this prospectus. Each broker-dealer that receives Exchange Notes for its own account in exchange for Original Notes, where such

Original Notes were acquired by such broker-dealer as a result of market-making or other trading activities, must acknowledge that it will deliver a prospectus meeting the requirements of the Securities Act (or, to the extent permitted by law, make available a prospectus meeting the requirements of the Securities Act to purchasers) in connection with any resale of such Exchange Notes. See “Plan of Distribution.”

In the registration rights agreements, we agreed that in the event that:

If the exchange offer registration statement is not on file with the SEC on or prior to the applicable Target Filing Date, or, if applicable, the shelf registration statement is required to be filed but is not on file with the SEC on or prior to the applicable Target Filing Date, or if applicable, the shelf registration statement is declared effective but thereafter ceases to be effective or usable and such failure to remain effective or usable exists for more than 120 days (whether or not consecutive) in any 12-month period (in each case subject to certain exceptions), then, upon the occurrence of any such events, additional interest shall accrue on the principal amount of the Original Notes at a rate of 0.25% per annum for the first 90-day period beginning on and including such date, increasing by an additional 0.25% per annum with respect to any subsequent 90-day period up to a maximum amount of additional interest of

0.50% in the aggregate per annum thereafter, until the Original Notes cease to be registrable securities or, if earlier, when the exchange offer is completed, the shelf registration statement becomes effective or, if such shelf registration statement ceased to be effective, when such shelf registration statement again becomes effective. Such interest will be computed ratably on the basis of twelve 30-day months.

Under certain circumstances, we and the guarantors may delay the filing or the effectiveness of the exchange offer registration statement or the shelf registration statement and will not be required to maintain the effectiveness thereof or amend or supplement the exchange offer registration statement or the shelf registration statement for one or more periods not to exceed an aggregate of 120 days during any 12-month period. Any delay period will not defer our obligation to pay additional interest.

This summary of certain provisions of the registration rights agreements does not purport to be complete and is subject to, and is qualified in its entirety by reference to, all the provisions of the applicable registration rights agreement. A copy of each registration rights agreement is an exhibit to the registration statement that includes this prospectus.

Upon the terms and subject to the conditions described in this prospectus and in the letter of transmittal, we will accept for exchange any Original Notes properly tendered and not withdrawn prior to the expiration time of the exchange offer. We will issue $1,000 principal amount of Exchange Notes in exchange for each $1,000 principal amount of Original Notes surrendered under the exchange offer and accepted by us. Original Notes may be tendered only in integral multiples of $1,000, subject to a $2,000 minimum, and untendered Original Notes may only be in a minimum denomination of $2,000 and integral multiples of $1,000 in excess thereof.

The terms of the Exchange Notes are identical in all material respects to those of the Original Notes, except the Exchange Notes will not be subject to transfer restrictions and holders of the Exchange Notes, with limited exceptions, will have no registration rights. Also, the Exchange Notes will not include provisions contained in the Original Notes that required payment of additional interest in the event we failed to satisfy our registration obligations with respect to the Original Notes. Each series of Exchange Notes will be issued under and entitled to the benefits of the same indenture that authorized the issuance of the related Original Notes.

The exchange offer is not conditioned on any minimum aggregate principal amount of Original Notes being tendered for exchange.

As of the date of this prospectus, $500,000,000 in aggregate principal amount of the unregistered 2.400% Senior Secured Notes due 2029, $1,000,000,000 in aggregate principal amount of the unregistered 2.700% Senior Secured Notes due 2032, $2,800,000,000 in aggregate principal amount of the unregistered 3.400% Senior Secured Notes due 2052, and $700,000,000 in aggregate principal amount of the unregistered 3.600% Senior Secured Notes due 2060 are outstanding. This prospectus and the letter of transmittal are being sent to all registered holders of the Original Notes. There will be no fixed record date for determining registered holders of the Original Notes entitled to participate in the exchange offer.

We intend to conduct the exchange offer in accordance with the provisions of the registration rights agreements, the applicable requirements of the Securities Act and the Exchange Act, and the SEC rules and regulations. Original Notes that are not tendered for exchange in the exchange offer:

We will be deemed to have accepted for exchange properly tendered Original Notes when we have given written notice of the acceptance to the exchange agent and complied with the applicable provisions of the registration rights agreements. The exchange agent will act as agent for the tendering holders for the purposes of receiving the Exchange Notes from us. We will issue the Exchange Notes promptly after the expiration of the exchange offer.

If you tender Original Notes in the exchange offer, you will not be required to pay brokerage commissions or fees or, subject to the instructions in the letter of transmittal, transfer taxes with respect to the exchange of Original Notes. We will pay all charges and expenses, other than certain applicable taxes described below, in connection with the exchange offer. It is important that you read “—Fees and Expenses” below for more details about fees and expenses incurred in the exchange offer.

We will return any Original Notes that we do not accept for exchange for any reason without expense to the tendering holder as promptly as practicable after the expiration or termination of the exchange offer.

The exchange offer is not subject to any federal or state regulatory requirements or approvals other than securities laws and blue sky laws.

The exchange offer will expire at 5:00 p.m., New York City time, on     , 2022, unless at our sole discretion we extend the exchange offer.

We expressly reserve the right, at any time or at various times, to extend the period of time during which the exchange offer is open. We may delay acceptance for exchange of any Original Notes by giving oral or written notice of the extension to their holders. During any such extensions, all Original Notes you have previously tendered will remain subject to the exchange offer for that series, and we may accept them for exchange.

To extend the exchange offer, we will notify the exchange agent orally or in writing (if oral to be promptly confirmed in writing) of any extension. We also will make a public announcement of the extension no later than 9:00 a.m., New York City time, on the next business day after the previously scheduled expiration time.

If any of the conditions described below under “—Conditions to the Exchange Offer” have not been satisfied with respect to the exchange offer, we reserve the right, at our sole discretion:

We will give oral or written notice (if oral to be promptly confirmed in writing) of such extension, delay or termination to the exchange agent. Subject to the terms of the registration rights agreements, we also reserve the right to amend the terms of the exchange offer in any manner.

Any such extension, delay in acceptance, termination or amendment will be followed as promptly as practicable by oral or written notice thereof to the registered holders of the Original Notes. If we amend the exchange offer in a manner that we determine to constitute a material change, we will promptly disclose that amendment by means of a prospectus supplement and we will extend the offer period if necessary so that at least five business days remain in the offer period following notice of the material change. We will distribute the supplement to the registered holders of the Original Notes. Depending on the significance of the amendment and the manner of disclosure to the registered holders, we may extend, pursuant to the terms of the registration rights agreements and the requirements of federal securities law, the exchange offer if the exchange offer would otherwise expire during such period.

Without limiting the manner in which we may choose to make public announcements of any extension, delay in acceptance, termination or amendment of the exchange offer, we have no obligation to publish, advertise or otherwise communicate any such public announcement, other than by making a timely release to an appropriate news agency.

Notwithstanding any other provision of the exchange offer and subject to the terms of the registration rights agreements, we will not be required to accept for exchange, or to issue Exchange Notes in exchange for, any Original Notes and may terminate or amend the exchange offer, if at any time before the expiration time of the exchange offer any of the following events occur:

In addition, we will not be obligated to accept for exchange the Original Notes of any holder that has not made to us:

We expressly reserve the right to amend or terminate the exchange offer notwithstanding the satisfaction of the foregoing, and to reject for exchange any Original Notes upon the occurrence of any of the conditions to the exchange offer specified above. We will give oral or written notice of any extension, non-acceptance, termination or amendment to the holders of the Original Notes as promptly as practicable.

These conditions are for our sole benefit, and we may assert them or waive them in whole or in part at any time or at various times at our sole discretion. Our failure at any time to exercise any of these rights will not mean that we have waived our rights. Each right will be deemed an ongoing right that we may assert at any time or at various times. If we waive a condition, we may be required in order to comply with applicable securities laws, to extend the expiration time of the exchange offer.

In addition, we will not accept for exchange any Original Notes tendered, and will not issue Exchange Notes in exchange for any such Original Notes, if at such time any stop order has been threatened or is in effect with respect to the registration statement of which this prospectus constitutes a part or the qualification of the indentures relating to the Exchange Notes under the Trust Indenture Act of 1939.

Only a holder of the Original Notes as determined by our records or those of Deutsche Bank Trust Company Americas, as trustee or DTC may tender Original Notes in the exchange offer. To tender in the exchange offer, a holder must either (1) comply with the procedures for physical tender or (2) comply with the automated tender offer program procedures of DTC, described below.

To complete a physical tender, a holder must:

To be tendered effectively, the exchange agent must receive any physical delivery of the letter of transmittal and other required documents at its address provided above under “Prospectus Summary—The Exchange Agent” prior to the expiration time.

To complete a tender through DTC’s automated tender offer program, the exchange agent must receive, prior to the expiration time, a timely confirmation of book-entry transfer of such Original Notes into the exchange agent’s account at DTC according to the procedure for book-entry transfer described below or a properly transmitted agent’s message.

The tender by a holder that is not withdrawn prior to the expiration time and our acceptance of that tender will constitute an agreement between the holder and us in accordance with the terms and subject to the conditions described in this prospectus and in the letter of transmittal.

THE METHOD OF DELIVERY OF ORIGINAL NOTES, THE LETTER OF TRANSMITTAL AND ALL OTHER REQUIRED DOCUMENTS TO THE EXCHANGE AGENT IS AT YOUR ELECTION AND RISK. RATHER THAN MAIL THESE ITEMS, WE RECOMMEND THAT YOU USE AN OVERNIGHT OR HAND DELIVERY SERVICE. IN ALL CASES, YOU SHOULD ALLOW SUFFICIENT TIME TO ENSURE

DELIVERY TO THE EXCHANGE AGENT BEFORE THE EXPIRATION TIME. YOU SHOULD NOT SEND THE LETTER OF TRANSMITTAL OR ORIGINAL NOTES TO US. YOU MAY REQUEST YOUR BROKER, DEALER, COMMERCIAL BANK, TRUST COMPANY OR OTHER NOMINEE TO EFFECT THE ABOVE TRANSACTIONS FOR YOU.

If you beneficially own Original Notes that are registered in the name of a broker, dealer, commercial bank, trust company or other nominee and you wish to tender those Original Notes, you should contact the registered holder as soon as possible and instruct the registered holder to tender on your behalf. If you are a beneficial owner and wish to tender on your own behalf, you must, prior to completing and executing the letter of transmittal and delivering your Original Notes, either:

The transfer of registered ownership may take considerable time and may not be completed prior to the expiration time.

You must have signatures on a letter of transmittal or a notice of withdrawal described below under “—Withdrawal of Tenders” guaranteed by an eligible institution unless the Original Notes are tendered:

An “eligible institution” is member firm of a registered national securities exchange or of the Financial Industry Regulatory Authority, Inc., a commercial bank or trust company having an office or correspondent in the United States, or an eligible guarantor institution within the meaning of Rule 17Ad-15 under the Exchange Act, that is a member of one of the recognized signature guarantee programs identified in the letter of transmittal.

If a person other than the registered holder of any Original Notes signs the letter of transmittal, the Original Notes must be endorsed or accompanied by a properly completed bond power. The registered holder must sign the bond power as the registered holder’s name appears on the Original Notes. An eligible institution must guarantee that signature.

If the letter of transmittal or any Original Notes or bond powers are signed by trustees, executors, administrators, guardians, attorneys-in-fact, or officers of corporations or others acting in a fiduciary or representative capacity, those persons should so indicate when signing. Unless we waive this requirement, they also must submit evidence satisfactory to us of their authority to deliver the letter of transmittal.

The exchange agent and DTC have confirmed that any financial institution that is a participant in DTC’s system may use DTC’s automated tender offer program to tender. Accordingly, participants in the program may, instead of physically completing and signing the letter of transmittal and delivering it to the exchange agent, transmit their acceptance of the exchange offer electronically. They may do so by causing DTC to transfer the Original Notes to the exchange agent in accordance with its procedures for transfer. DTC will then send an agent’s message to the exchange agent.

An agent’s message is a message transmitted by DTC to and received by the exchange agent and forming part of the book-entry confirmation, stating that:

We will determine at our sole discretion all questions as to the validity, form, eligibility, time of receipt, acceptance of tendered Original Notes and withdrawal of tendered Original Notes. Our determination will be final and binding. We reserve the absolute right to reject any Original Notes not properly tendered or any Original Notes our acceptance of which, in the opinion of our counsel, might be unlawful. Our interpretation of the terms and conditions of the exchange offer, including the instructions in the letter of transmittal, will be final and binding on all parties.

Unless waived, any defects or irregularities in connection with tenders of Original Notes must be cured within such time as we determine. Neither we, the exchange agent nor any other person will be under any duty to give notification of defects or irregularities with respect to tenders of Original Notes, nor will we or those persons incur any liability for failure to give such notification. Tenders of Original Notes will not be deemed made until such defects or irregularities have been cured or waived. Any Original Notes received by the exchange agent that are not properly tendered and as to which the defects or irregularities have not been cured or waived will be returned to the tendering holder, unless otherwise provided in the letter of transmittal, as soon as practicable following the expiration time.

In all cases, we will issue Exchange Notes for Original Notes that we have accepted for exchange in the exchange offer only after the exchange agent timely receives:

If we do not accept any tendered Original Notes for exchange for any reason described in the terms and conditions of the exchange offer or if Original Notes are submitted for a greater principal amount than the holder desires to exchange, we will return the unaccepted or non-exchanged Original Notes without expense to their tendering holder. In the case of Original Notes tendered by book-entry transfer into the exchange agent’s account at DTC according to the procedures described below, such non-exchanged Original Notes will be credited to an account maintained with DTC. These actions will occur as promptly as practicable after the expiration or termination of the exchange offer.

By signing or agreeing to be bound by the letter of transmittal, you will represent to us that, among other things:

The exchange agent will make a request to establish an account with respect to the Original Notes at DTC for purposes of the exchange offer promptly after the date of this prospectus. Any financial institution participating in DTC’s system may make book-entry delivery of Original Notes by causing DTC to transfer such Original Notes into the exchange agent’s account at DTC in accordance with DTC’s procedures for transfer.

Each broker-dealer that receives Exchange Notes for its own account in exchange for Original Notes, where such Original Notes were acquired by such broker-dealer as a result of market-making or other trading activities, must acknowledge that it will deliver a prospectus meeting the requirements of the Securities Act (or, to the extent permitted by law, make available a prospectus meeting the requirements of the Securities Act to purchasers) in connection with any resale of such Exchange Notes. See “Plan of Distribution.”

Except as otherwise provided in this prospectus, you may withdraw your tender at any time prior to the expiration time. For a withdrawal to be effective:

Any notice of withdrawal must:

If Original Notes have been tendered under the procedure for book-entry transfer described above, any notice of withdrawal must specify the name and number of the account at DTC to be credited with the withdrawn Original Notes and otherwise comply with the procedures of DTC.

We will determine all questions as to the validity, form, eligibility and time of receipt of notice of withdrawal, and our determination shall be final and binding on all parties. We will deem any Original Notes so withdrawn not to have been validly tendered for exchange for purposes of the exchange offer.

Any Original Notes that have been tendered for exchange but that are not exchanged for any reason will be returned to their holder without cost to the holder, or, in the case of Original Notes tendered by book-entry transfer into the exchange agent’s account at DTC according to the procedures described above, such Original Notes will be credited to an account maintained with DTC for the Original Notes. This return or crediting will take place as soon as practicable after withdrawal, rejection of tender or termination of the exchange offer. You may retender properly withdrawn Original Notes by following one of the procedures described above under “—Procedures for Tendering” at any time on or prior to the expiration time.

We will bear the expenses of soliciting tenders. The principal solicitation is being made by mail; however, we may make additional solicitation by facsimile, email, telephone or in person by our officers and regular employees and those of our affiliates.

We have not retained any dealer-manager in connection with the exchange offer and will not make any payments to broker-dealers or others soliciting acceptances of the exchange offer. We will, however, pay the exchange agent

reasonable and customary fees for its services and reimburse it for its related reasonable out-of-pocket expenses. We may also pay brokerage houses and other custodians, nominees and fiduciaries the reasonable out-of-pocket expenses incurred by them in forwarding copies of this prospectus, letters of transmittal and related documents to the beneficial owners of the Original Notes and in handling or forwarding tenders for exchange.

We will pay cash expenses to be incurred in connection with the exchange offer. They include:

If you tender your Original Notes for exchange, you will not be required to pay any transfer taxes. We will pay all transfer taxes, if any, applicable to the exchange of Original Notes in the exchange offer. The tendering holder will, however, be required to pay any transfer taxes, whether imposed on the registered holder or any other person, if:

If satisfactory evidence of payment of any transfer taxes payable by a tendering holder is not submitted with the letter of transmittal, the amount of the transfer taxes will be billed directly to that tendering holder. The exchange agent will retain possession of Exchange Notes with a face amount equal to the amount of the transfer taxes due until it receives payment of the taxes.

We will record the Exchange Notes at the same carrying value as the Original Notes as reflected in our accounting records on the date of the exchange. Accordingly, we will not recognize any gain or loss for accounting purposes upon completion of the exchange offer.

If you do not exchange your Original Notes for Exchange Notes in the exchange offer, you will remain subject to the existing restrictions on transfer of the Original Notes. In general, you may not offer or sell the Original Notes unless either they are registered under the Securities Act or the offer or sale is exempt from or not subject to registration under the Securities Act and applicable state securities laws. Except as required by the registration rights agreements, we do not intend to register resales of the Original Notes under the Securities Act. We generally have no obligation to re-offer to exchange the Exchange Notes for Original Notes following the expiration of the exchange offer. The tender of Original Notes in the exchange offer will reduce the outstanding principal amount of the Original Notes. Due to the corresponding reduction in liquidity, this may have an adverse effect on, and increase the volatility of, the market price of any Original Notes that you continue to hold. See “Risk Factors—Risks Related to the Exchange Offer—If you do not exchange your Original Notes, your Original Notes will continue to be subject to the existing transfer restrictions and you may be unable to sell your outstanding Original Notes.”

Participation in the exchange offer is voluntary, and you should carefully consider whether to accept. You are urged to consult your financial and tax advisors in making your decision on what action to take.

In the future, we may at our discretion seek to acquire untendered Original Notes in open market or privately negotiated transactions, through subsequent exchange offers or otherwise. We have no present plan to acquire any Original Notes that are not tendered in the exchange offer or to file a registration statement to permit resales of any untendered Original Notes, except as required by the registration rights agreements.

T-Mobile USA, Inc., a Delaware corporation (the “Issuer”), is offering to exchange, upon the terms and conditions set forth in this prospectus and the accompanying letter of transmittal, up to $500,000,000 in aggregate principal amount of 2.400% Senior Secured Notes due 2029 (the “2029 Exchange Notes”), $1,000,000,000 in aggregate principal amount of 2.700% Senior Secured Notes due 2032 (the “2032 Exchange Notes”), $2,800,000,000 in aggregate principal amount of 3.400% Senior Secured Notes due 2052 (the “2052 Exchange Notes”) and $700,000,000 in aggregate principal amount of 3.600% Senior Secured Notes due 2060 (the “2060 Exchange Notes” and, together with the 2029 Exchange Notes, the 2032 Exchange Notes and the 2052 Exchange Notes, the “Exchange Notes”) for, in each case, an equal amount of its outstanding 2.400% Senior Secured Notes due 2029 (the “2029 Original Notes” and collectively with the 2029 Exchange Notes, the “2029 Notes”), 2.700% Senior Secured Notes due 2032 (the “2032 Original Notes” and collectively with the 2032 Exchange Notes, the “2032 Notes”), 3.400% Senior Secured Notes due 2052 (the “2052 Original Notes” and collectively with the 2052 Exchange Notes, the “2052 Notes”), and 3.600% Senior Secured Notes due 2060 (the “2060 Original Notes” and collectively with the 2060 Exchange Notes, the “2060 Notes” and the 2060 Original Notes together with the 2029 Original Notes, the 2032 Original Notes and the 2052 Original Notes, the “Original Notes” and collectively with the Exchange Notes, the “Notes”).

The Original Notes were issued, and the Exchange Notes will be issued, under a base indenture (the “Base Indenture”), dated as of April 9, 2020, among the Issuer, T-Mobile US, Inc., a Delaware corporation and the direct parent company of 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 2029 Notes by the Twenty-First Supplemental Indenture, dated as of December 6, 2021 (the “2029 Notes Supplemental Indenture”), (ii) with respect to the 2032 Notes by the Twenty-Second Supplemental Indenture, dated as of December 6, 2021 (the “2032 Notes Supplemental Indenture”), (iii) with respect to the 2052 Notes by the Nineteenth Supplemental Indenture, dated as of August 13, 2021, and the Twenty-Third Supplemental Indenture, dated as of December 6, 2021 (collectively, the “2052 Notes Supplemental Indenture”) and (iv) with respect to the 2060 Notes by the Seventeenth Supplemental Indenture, dated as of October 28, 2020, and the Twentieth Supplemental Indenture, dated as of August 13, 2021 (collectively, the “2060 Notes Supplemental Indenture” and each of the 2029 Notes Supplemental Indenture, the 2032 Notes Supplemental Indenture, the 2052 Notes Supplemental Indenture and the 2060 Notes Supplemental Indenture, with respect to the applicable series of Notes, the “Supplemental Indenture”), each 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.

The 2060 Original Notes were an additional issuance of the 3.600% Senior Secured Notes due 2060 issued by the Issuer in an aggregate principal amount of $1,000,000,000 on October 28, 2020, which were subsequently exchanged for notes having substantially identical terms, except that such exchange notes generally are freely tradable and do not contain certain terms with respect to registration rights and additional interest (the “Existing Registered 2060 Notes”). The 2060 Original Notes are consolidated with and form a single series with the Existing Registered 2060 Notes and have the same respective terms other than the settlement date, offering price, initial interest payment date and registration rights. However, the 2060 Original Notes are not fungible with the Existing Registered 2060 Notes, and unless and until exchanged for 2060 Exchange Notes pursuant to this exchange offer, the 2060 Original Notes will have separate CUSIP numbers from, and will not be fungible with, the Existing Registered 2060 Notes.

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. 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 Original Notes and will be a guarantor of the Exchange Notes, Parent and any of its Subsidiaries that are not the Issuer or the Issuer’s Subsidiaries generally are not and will not be subject to any of the obligations and covenants described hereunder.

The following description is a summary of the material provisions of the Indenture, the Security Documents and the Intercreditor Agreement applicable to both the Exchange Notes and the Original Notes. As such, when we refer to a series of Notes, we are describing the material provisions of the corresponding series of both the Original Notes and the Exchange Notes, and when we refer to the Notes, we are describing the material provisions of both the Original Notes and the Exchange Notes. The following description does not restate the terms of the Indenture, the Security Documents and the Intercreditor Agreement in their entirety. We urge you to read the Indenture, the Security Documents and the Intercreditor Agreement in their entirety because they, and not this Description of Notes, define your rights as a holder of Original Notes or Exchange Notes, as applicable. For more information on how you can obtain a copy of the Base Indenture, Supplemental Indentures, Security Documents and the Intercreditor Agreement, 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 Security Documents or the Intercreditor Agreement.

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. The Original Notes were issued initially in a private transaction that was not subject to the registration requirements of the Securities Act of 1933, as amended (the “Securities Act”).

The Original Notes of each series are, and the Exchange Notes of each series will be:

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

The Original Notes are, and the Exchange Notes will be, guaranteed by (i) Parent and any Wholly-Owned Subsidiary of the Issuer that (x) is not an Excluded Subsidiary and (y) is an obligor under (1) the Credit Agreement or (2) assuming such Subsidiary is not an “Unrestricted Subsidiary” (or the equivalent thereof) under the Credit

Agreement, any capital markets debt securities in an aggregate principal amount in excess of $500.0 million and (ii) any future direct or indirect Subsidiary of Parent or any Subsidiary of Parent that directly or indirectly owns Capital Stock of the Issuer. Such entities 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 (the “Sprint Guarantors”). These Note Guarantees are (with respect to Original Notes) or will be (with respect to Exchange Notes) joint and several obligations of the Guarantors. The obligations of each Guarantor under its Note Guarantee is (with respect to Original Notes) or will be (with respect to Exchange Notes) limited as necessary to prevent that Note Guarantee from constituting a fraudulent conveyance under applicable law. See “Risk Factors—Risks Related to the Notes—The Guarantees (or the related security interests) may be avoidable and therefore not be enforceable because of fraudulent conveyance or fraudulent transfer laws.”

Each Note Guarantee of the Notes by a Guarantor is (with respect to Original Notes) or will be (with respect to Exchange Notes):

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

The Issuer’s existing and future Subsidiaries are or will be required to guarantee the Notes only under the circumstances described below under the subheading “—Certain Covenants—Additional Note Guarantees.” 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:

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. The 2052 Original Notes issued by the Issuer in an aggregate principal amount of $1,500,000,000 on December 6, 2021, and the 2060 Original Notes, constitute additional Notes of the applicable series under the Indenture. 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, together with any Exchange Notes issued with respect to such series in accordance with the applicable Registration Rights Agreement, 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 Notes of any series and any such further additional Notes will be secured equally and ratably by the Liens on the Collateral described below under the heading “—Collateral”.

The Issuer issued the Original Notes, and will issue the Exchange Notes, in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof.

The 2029 Notes will mature on March 15, 2029, the 2032 Notes will mature on March 15, 2032, the 2052 Notes will mature on October 15, 2052, and the 2060 Notes will mature on November 15, 2060.

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 (and, in the case of Exchange Notes, interest will accrue from the date of original issuance or, if interest has already been paid on the corresponding Original Notes exchanged therefor, the date it was most recently paid on such Original Notes). 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 Original Notes is, and interest on the Exchange Notes will be, computed on the basis of a 360-day year consisting of twelve 30-day months.

Interest on the 2029 Original Notes accrues, and interest on the 2029 Exchange Notes will accrue, at the rate of 2.400% per annum; interest on the 2032 Original Notes accrues, and interest on the 2032 Exchange Notes will

accrue, at the rate of 2.700% per annum; interest on the 2052 Original Notes accrues, and interest on the 2052 Exchange Notes will accrue, at the rate of 3.400% per annum and interest on the 2060 Original Notes accrues, and interest on the 2060 Exchange Notes will accrue, at the rate of 3.600% per annum.

Interest on the 2029 Original Notes and the 2032 Original Notes is, and interest on the 2029 Exchange Notes and the 2032 Exchange Notes will be, payable semiannually in arrears on March 15 and September 15. The Issuer will make each interest payment to the holders of record of the 2029 Notes and the 2032 Notes on the immediately preceding March 1 or September 1 (whether or not a Business Day). Interest on the 2052 Original Notes is, and interest on the 2052 Exchange Notes will be, payable semiannually in arrears on April 15 and October 15. The Issuer will make each interest payment to the holders of record of the 2052 Notes on the immediately preceding April 1 or October 1 (whether or not a Business Day). Interest on the 2060 Original Notes is, and interest on the 2060 Exchange Notes will be, payable semiannually in arrears on May 15 and November 15. The Issuer will make each interest payment to the holders of record of the 2060 Notes on the immediately preceding May 1 or November 1 (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.”

The Original Notes of each series are, and the Exchange Notes of 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”).

The Notes are not, and 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 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.

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.

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.

The Issuer will not be required to make any mandatory redemption or sinking fund payments with respect to the Notes. However, under certain circumstances, the Issuer may be required to offer to purchase Notes as described below under the caption “—Repurchase at the Option of Holders.”

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.

Prior to the applicable Par Call Date with respect to each series of Notes, the Original Notes of such series are, and the Exchange Notes of such series will be, redeemable, in whole or in part, at the Issuer’s option, at any time or from time to time, on at least 10 days’ (in the case of the 2029 Notes and the 2032 Notes) and at least 15 days’ (in the case of the 2052 Notes and the 2060 Notes) but not more than 60 days’ prior notice to the holders of the Notes of such series to be redeemed, at a redemption price equal to the greater of:

On or after the applicable Par Call Date with respect to each series of Notes, the Notes of such series will be redeemable, in whole or in part, at the Issuer’s option, at any time or from time to time, on at least 10 days’ (in the case of the 2029 Notes and the 2032 Notes) and at least 15 days’ (in the case of the 2052 Notes and the 2060 Notes) but not more than 60 days’ prior notice to the holders of such series to be redeemed, at a redemption price equal to 100% of the principal amount thereof.

In each case, we will also pay the accrued and unpaid interest on the principal amount being redeemed to, but not including, the redemption date.

“Comparable Treasury Issue” means the United States Treasury security selected by an Independent Investment Bank as having a constant maturity comparable to the remaining term of the Notes to be redeemed (assuming that such Notes matured on their applicable Par Call Date) that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of such Notes (assuming that such Notes matured on their applicable Par Call Date).

“Comparable Treasury Price” means, with respect to any redemption date, (1) the average of the Reference Treasury Dealer Quotations for such redemption date, after excluding the highest and lowest Reference Treasury Dealer Quotations, or (2) if the Independent Investment Bank obtains fewer than four such Reference Treasury Dealer Quotations, the average of all such quotations.

“Independent Investment Bank” means one of the Reference Treasury Dealers that the Issuer appoints to act as the Independent Investment Bank from time to time.

“Par Call Date” means (i) with respect to the 2029 Notes, January 15, 2029 (two months prior to the maturity date of such 2029 Notes), (ii) with respect to the 2032 Notes, December 15, 2031 (three months prior to the maturity date of such 2032 Notes), (iii) with respect to the 2052 Notes, April 15, 2052 (six months prior to the maturity date of such 2052 Notes) and (iv) with respect to the 2060 Notes, May 15, 2060 (six months prior to the maturity date of such 2060 Notes).

“Reference Treasury Dealer” means (1) (A) with respect to the 2029 Notes and the 2032 Notes, each of Barclays Capital Inc., Credit Suisse Securities (USA) LLC and Goldman Sachs & Co. LLC, and in each case their respective successors, unless any of them ceases to be a primary U.S. Government securities dealer in New York City (a “Primary Treasury Dealer”), in which case we will substitute another Primary Treasury Dealer, (B) with respect to the 2052 Notes, each of Citigroup Global Markets Inc., Deutsche Bank Securities Inc. and J.P. Morgan Securities LLC, and in each case their respective successors, unless any of them ceases to be a Primary Treasury Dealer, in

which case we will substitute another Primary Treasury Dealer, and (C) with respect to the 2060 Notes, each of Citigroup Global Markets Inc., Credit Suisse Securities (USA) LLC, Deutsche Bank Securities Inc. and Goldman Sachs & Co. LLC, and in each case their respective successors, unless any of them ceases to be a Primary Treasury Dealer, in which case we will substitute another Primary Treasury Dealer, and (2) any other Primary Treasury Dealer(s) we select.

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by the Independent Investment Bank, of the bid and asked prices for the applicable Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Independent Investment Bank by such Reference Treasury Dealer at 5:00 p.m., New York City time, on the third business day preceding such redemption date.

“Treasury Rate” means, with respect to any redemption date, (i) the yield, calculated as the average of the five most recent daily rates published in the statistical release(s) designated “H.15” or any successor publication which is published by the Board of Governors of the Federal Reserve System and which establishes yields on actively traded U.S. Treasury securities adjusted to constant maturity under the caption “Treasury Constant Maturities,” for the maturity corresponding to the Comparable Treasury Issue (if no maturity is within three months before or after the Par Call Date, yields for the two published maturities most closely corresponding to the Comparable Treasury Issue shall be determined and the Treasury Rate shall be interpolated or extrapolated from such yields on a straight line basis, rounding to the nearest month); or (ii) if the release referred to above (or any successor release) is not published during the week preceding the calculation date or does not contain the yields referred to above, the rate per annum equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such redemption date. The Treasury Rate will be calculated at 5:00 p.m. (New York City time) on the third business day preceding such redemption date. As used in the immediately preceding sentence and in the definition of “Reference Treasury Dealer Quotations” above, the term “business day” means any day that is not a Saturday, Sunday or other day on which commercial banks in New York City are authorized or obligated by law or executive order to close.

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.

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.

If a Change of Control Triggering Event occurs with respect to any series of Notes, each holder of outstanding Notes of such series will have the right to require the Issuer to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of that holder’s Notes of such series pursuant to a Change of Control Offer on the terms set forth in the Indenture. In the Change of Control Offer, the Issuer will offer a Change of Control Payment in cash equal to 101% of the aggregate principal amount of Notes repurchased plus accrued and unpaid

interest, if any, on the Notes repurchased to, but not including, the date of purchase, subject to the rights of holders of Notes on the relevant record date to receive interest due on the relevant interest payment date for periods prior to such repurchase date (the “Change of Control Payment”). Within 30 days following any Change of Control Triggering Event, the Issuer will send a notice (the “Change of Control Offer”) to each holder of Notes to which such Change of Control Triggering Event applies and the Trustee describing the transaction or transactions and identifying the rating event that together constitute the Change of Control Triggering Event and offering to repurchase the Notes of such series on the Change of Control Payment Date specified in the notice, which date will be no earlier than 10 days and no later than 60 days from the date such notice is sent (the “Change of Control Payment Date”), pursuant to the procedures required by the Indenture and described in such notice. The Issuer will comply with the requirements of Rule 14e-1 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control Triggering Event. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control Triggering Event provisions of the Indenture, or compliance with the Change of Control Triggering Event provisions of the Indenture would constitute a violation of any such laws or regulations, the Issuer will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Change of Control Triggering Event provisions of the Indenture by virtue of such compliance. In connection with the tender of any Notes with respect to a Change of Control Triggering Event, the tendering holder shall provide good title to the Notes, free and clear of all liens and encumbrances, and shall represent and warrant that such holder is presenting good title, free and clear of all liens and encumbrances, and such other representations and warranties as are customary.

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

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

Except as described above with respect to a Change of Control Triggering Event, the Indenture does not contain provisions that permit the holders of the Notes to require, or otherwise provide, that the Issuer repurchase or redeem the Notes in the event of a takeover, recapitalization or similar transaction.

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

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

In the event that holders of not less than 90% of the aggregate principal amount of the outstanding Notes of a series accept a Change of Control Offer and the Issuer purchases all of the Notes of such series held by such holders, the Issuer will have the right, upon not less than 10 nor more than 60 days’ notice, given not more than 30 days following the purchase pursuant to the Change of Control Offer described above, to redeem all of the Notes of such

series that remain outstanding following such purchase at a redemption price equal to the Change of Control Payment plus, to the extent not included in the Change of Control Payment, accrued and unpaid interest, if any, thereon, to, but not including, the redemption date (subject to the right of holders of record on the relevant record date to receive interest due on an interest payment date that is on or prior to the redemption date).

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

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, 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 (in the case of the 2029 Notes and the 2032 Notes) and at least 15 days (in the case of the 2052 Notes and the 2060 Notes) 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 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 or offer to purchase that payment of the redemption or purchase price and performance of the Issuer’s obligations with respect to such redemption or offer to purchase 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.

The Issuer, the Secured Guarantors and the Collateral Trustee have entered into the Security Documents in connection with the Credit Agreement, the Original Notes and the other Existing T-Mobile Secured Notes. The Security Documents have been supplemented by Notices of Designation executed by the Issuer and agreed to by the Collateral Trustee pursuant to the Intercreditor Agreement (the “Note Notices of Designation”) to establish that the Original Notes and the Note Guarantees with respect thereto (other than the Note Guarantees with respect thereto provided by Sprint, Sprint Communications and Sprint Capital Corporation, which are unsecured) are, and the Exchange Notes and the Note Guarantees with respect thereto (other than the Note Guarantees with respect thereto provided by Sprint, Sprint Communications and Sprint Capital Corporation, which will be unsecured) will be, secured on a pari passu basis with the obligations under the other Existing T-Mobile Secured Notes, the Credit Agreement, up to $3.5 billion of lease payment obligations under the Existing Sprint Spectrum Lease, obligations under the Designated L/C Facilities and any other permitted First Priority Secured Obligations by perfected first-priority security interests in substantially all of the present and future assets and property of the Issuer and the Secured Guarantors, other than Excluded Assets and subject to Permitted Liens. The 2052 Original Notes issued by

the Issuer in an aggregate principal amount of $1,500,000,000 on December 6, 2021, and the 2052 Original Notes issued by the Issuer in an aggregate principal amount of $1,300,000,000 on August 13, 2021 are treated as a single class of First Lien Obligations for purposes of the Intercreditor Agreement and the Security Documents. The 2060 Original Notes and the previously issued $1,000,000,000 in aggregate principal amount of the Issuer’s 3.600% Senior Secured Notes due 2060 are treated as a single class of First Lien Obligations for purposes of the Intercreditor Agreement and the Security Documents. The first lien secured parties other than the holders of the Notes have rights and remedies with respect to the Collateral that, if exercised, could also adversely affect the value of the Collateral benefiting the holders of the Notes, particularly the rights described below under “—The Collateral Trust and Intercreditor Agreement.”

The Issuer and the Guarantors are and will be able to incur additional Indebtedness in the future which could share in the Collateral, including First Priority Secured Obligations and obligations secured by Permitted Liens, and the amount of such Indebtedness could be significant. With respect to the Issuer and the Guarantors, the amount of such additional secured obligations will be limited by the covenants described under “—Certain Covenants—Liens.”

The Original Notes are, and the Exchange Notes will be, secured by first-priority Liens, subject to Permitted Liens, granted by Parent and any future 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 (a “Parent Only Subsidiary”), with respect to the following assets and property, in each case, wherever located and whether now owned or at any time hereafter acquired by Parent or a Parent Only Subsidiary or in which Parent or a Parent Only Subsidiary now has or at any time in the future may acquire any right, title or interest (the “Parent Collateral”):

The Original Notes also are, and the Exchange Notes will also be, secured by first-priority Liens, subject to Permitted Liens, granted by the Issuer and the Secured Guarantors (other than Parent and any Parent Only Subsidiary), with respect to the following assets and property, in each case, wherever located and whether now owned or at any time hereafter acquired by the Issuer and such Secured Guarantors or in which the Issuer or such Secured Guarantors now have or at any time in the future may acquire any right, title or interest (collectively, the “Non-Parent Collateral,” and collectively with the Parent Collateral, the “Collateral”):

The Collateral excludes (with respect to the Original Notes) and will exclude (with respect to the Exchange Notes), and the Liens granted under the Security Documents will not attach to, the following items of property (collectively, the “Excluded Assets”):

Neither the Intercreditor Agreement, the Indenture or any Security Document will require the Issuer or any Guarantor to: (i) perfect any pledges or security interests in the Collateral by any means other than filings under the UCC and the U.S. Patent and Trademark Office with respect to certain registered intellectual property or, where applicable, delivery of share certificates, (ii) deliver deposit or securities account control agreements or otherwise deliver perfection by “control” (within the meaning of the UCC) (except as provided in clause (i) with respect to delivery of share certificates), (iii) take any actions outside of the United States with respect to any assets located outside of the United States; or (iv) take any actions in any jurisdiction other than the United States in connection with pledging Collateral or enter into any collateral documents governed by the laws of any country other than the United States.

If the Issuer or any Secured Guarantor acquires any property or asset of the type that constitutes Collateral and that is not an Excluded Asset, it must promptly grant a security interest upon such property as security for the Notes. The Issuer will, and will cause each Secured Guarantor to, at the expense of the Issuer and such Secured Guarantors, make, execute, endorse, acknowledge, authorize, file and/or deliver to the Trustee or the Collateral Trustee from time to time such documents, assurances or instruments and take such further steps relating to the Collateral covered by any Security Document (other than Excluded Assets and subject to Permitted Liens) as the First Priority Agent may reasonably require to carry out the terms and conditions of the Indenture and the Security Documents and to ensure perfection (to the extent perfection is required under the Security Documents) and priority of the Liens created or intended to be created by the Security Documents; provided, however, that if at any time the First Priority Agent is not the agent in respect of any loan agreement, then the Issuer shall be responsible to ensure perfection (to the extent perfection is required under the Security Documents) and priority of the Liens created or intended to be created by the Security Documents.

The fair market value of the Collateral is subject to fluctuations based on factors that include, among others, the condition of Parent’s industry, the ability to sell the Collateral in an orderly sale, general economic conditions, the availability of buyers and other factors. The amount to be received upon a sale of the Collateral would also be dependent on numerous factors, including, but not limited to, the actual fair market value of the Collateral at such time and the timing and the manner of the sale. By its nature, portions of the Collateral may be illiquid and may have no readily ascertainable market value. Accordingly, there can be no assurance that the Collateral can be sold in a short period of time or in an orderly manner. In addition, in the event of a bankruptcy, the ability of the holders to realize upon any of the Collateral would be subject to certain bankruptcy law limitations as described above. See “Risk Factors—Risks Related to the Notes—Rights of the holders of the Notes in the Collateral securing the Notes may be adversely affected by bankruptcy proceedings and the holders of the Notes may not be entitled to post-petition interest, fees or expenses in any bankruptcy proceeding.”

Upon the occurrence and during the continuance of an Event of Default, subject to the terms of the Intercreditor Agreement, the Security Documents provide for (among other available remedies) the foreclosure upon and sale of the Collateral and the distribution of the net proceeds of any such sale to the holders of the Notes and the other Existing T-Mobile Secured Notes, the lenders under the Credit Agreement, the lessors under the Existing Sprint Spectrum Lease, the holders of any Designated L/C Facility Obligations and the holders of any other permitted First Priority Secured Obligations on a pro rata basis, subject to any prior Liens on the Collateral. In the event of foreclosure on the Collateral, the proceeds from the sale of the Collateral may not be sufficient to satisfy in full the Issuer’s obligations under the Notes.

The right of the Collateral Trustee to repossess and dispose of the Collateral upon the occurrence of an Event of Default would be significantly impaired (or at a minimum delayed) by applicable Bankruptcy Law in the event that a bankruptcy case were to be commenced by or against the Issuer or the Guarantors prior to the Collateral Trustee having repossessed and disposed of the Collateral (and in some cases, even after). Upon the commencement of a case for relief under the Bankruptcy Code or other applicable Bankruptcy Law, a secured creditor such as the Collateral Trustee is prohibited from repossessing its security from a debtor in a bankruptcy case, or from disposing of security repossessed from the debtor, without prior bankruptcy court approval (which may not be given under the circumstances).

In view of the broad equitable powers of a U.S. bankruptcy court and the lack of a precise definition of the term “adequate protection”, it is impossible to predict whether any payments under the Notes could be made following the commencement of or during a bankruptcy case or the length of any potential delay in making any such payments post-petition, whether or when the Collateral Trustee could foreclose upon, repossess or dispose of the Collateral, the value of the Collateral at the time of the bankruptcy petition, or whether or to what extent the holders of the Notes would be compensated for any delay in payment or loss of value of the Collateral. The Bankruptcy Code permits the payment and/or accrual of post-petition interest, costs, expenses, and fees to a secured creditor during a debtor’s bankruptcy case only to the extent the value of the security is determined by the bankruptcy court to exceed the aggregate outstanding principal amount of the obligations secured by the security. See “Risk Factors—Risks Related to the Notes—Rights of the holders of the Notes in the Collateral securing the Notes may be adversely affected by bankruptcy proceedings and the holders of the Notes may not be entitled to post-petition interest, fees or expenses in any bankruptcy proceeding.”

Furthermore, in the event a bankruptcy court determines that the value of the Collateral is not sufficient to repay all amounts due on the Notes (and all other claims that are secured thereby on a pari passu basis), the holders of the Notes would hold secured claims only to the extent of the value of the Collateral to which the holders are entitled and unsecured claims with respect to such shortfall, which unsecured claims would not be entitled to any adequate protection during a bankruptcy case.

The Indenture provides that Liens on the Collateral will be automatically and unconditionally released in respect of the Notes of any series:

Any certificate or opinion required by Section 314(d) of the Trust Indenture Act in connection with obtaining the release of Collateral may be made by an officer of the Issuer, except in cases where Section 314(d) requires that such certificate or opinion be made by an independent engineer, appraiser or other expert.

Notwithstanding anything to the contrary in this “Description of Notes” section, the Issuer and the Guarantors will not be required to comply with all or any portion of Section 314(d) of the Trust Indenture Act if they determine in good faith that under the terms of that section or any interpretation or guidance as to the meaning thereof of the

U.S. Securities and Exchange Commission (the “SEC”) and its staff, including “no action” letters or exemptive orders, all or the relevant portion of Section 314(d) of the Trust Indenture Act is inapplicable to the released Collateral. Certain no action letters issued by the SEC have permitted an indenture qualified under the Trust Indenture Act to contain provisions permitting the release of collateral from liens under such indenture in the ordinary course of the issuer’s business without requiring the issuer to provide certificates and other documents under Section 314(d).

Without limiting the generality of the foregoing, as permitted under the Trust Indenture Act and interpretations thereof and guidance promulgated with respect thereto, the Issuer and the Secured Guarantors generally may, pursuant to and subject to the terms of the Indenture and the Security Documents, without any release or consent by the Trustee, the Collateral Trustee or the holders, conduct ordinary course activities with respect to the Collateral, such as: (a) selling, transferring, exchanging, abandoning, leasing or otherwise disposing of property subject to the Liens securing the Notes; (b) holding, using, applying, disposing of and otherwise dealing with any cash equivalents, accounts receivable or other amounts from time to time; (c) altering, repairing or replacing property subject to the Liens securing the Notes; and (d) selling, disposing of or transferring any inventory that is Collateral.

The Indenture and the Security Documents provide (in the case of the Original Notes) and will provide (in the case of the Exchange Notes) that, upon the occurrence of such events in accordance with the Security Documents, the Liens securing the Notes will automatically and without the need for any further consent by the holders of Notes or the Trustee or the Collateral Trustee or any other action by any Person and subject to applicable law be released with respect to such Collateral. The Collateral Trustee shall, subject to the terms of the Intercreditor Agreement (including the Collateral Trustee’s receipt of any officer’s certificate(s) or opinion(s) of counsel it may be entitled to thereunder) execute such releases, satisfactions or assignments of lien, and take such related actions, as we may reasonably request and prepare.

The Indenture will require that, if such releases of Collateral occur, the Issuer will deliver to the Trustee and the Collateral Trustee, to the extent required by the Trust Indenture Act or interpretations thereof or guidance promulgated with respect thereto: (a) annual audited financial statements of Parent (which delivery will be deemed to have occurred to the extent such financial statements are filed with the SEC via EDGAR or any successor electronic delivery procedure) no later than the June 30 following the end of each fiscal year of Parent and (b) a certificate by January 15 and July 15 of each year stating that all such dispositions of Collateral occurring during the six months ended December 31 or June 30, respectively, prior to the date of such certificate occurred in the ordinary course of business, were permitted by the Security Documents and that the proceeds of any such dispositions were used as permitted by the Indenture and the Security Documents.

The right of the Collateral Trustee to repossess and dispose of the Collateral upon the occurrence of an Event of Default under the Indenture is subject to the provisions of the Intercreditor Agreement.

If the net proceeds of any of the Collateral were not sufficient to repay all amounts due on the Notes and the Indenture (and all other claims secured by the Collateral on a pari passu basis), the holders of the Notes (to the extent not repaid from the proceeds of the sale of the Collateral) would have only an unsecured claim against the remaining assets of the Issuer and the Secured Guarantors.

The Issuer, the Secured Guarantors, the Collateral Trustee, Deutsche Bank AG New York Branch, as First Priority Agent and as administrative agent under our Credit Agreement (together with its successors (including any administrative agent or entity serving an analogous function under a successor Credit Agreement), the “Credit Facility Agent”) and Deutsche Bank Trust Company Americas, as trustee under the Existing Sprint Spectrum Lease, have entered into a Collateral Trust and Intercreditor Agreement (as supplemented by the Note Notices of Designation and as amended, restated, amended and restated, supplemented or otherwise modified from time to time, the “Intercreditor Agreement”). The Trustee is party to the Intercreditor Agreement as a holder representative and indenture trustee under the Notes. The Original Notes are, and the obligations under the Exchange Notes will be, First Priority Secured Obligations. The Intercreditor Agreement sets forth the terms on which the Collateral Trustee will receive, hold, administer, maintain, enforce and distribute the proceeds of all Liens upon any property of the Issuer or any Secured Guarantor at any time held by it, in trust for the benefit of the current and future holders of the First Priority Secured Obligations and future holders of obligations secured by a Lien on the Collateral that is junior to the Lien on the Collateral securing the Notes, the other Existing T-Mobile Secured Notes and the other First Priority

Secured Obligations. The Intercreditor Agreement may be amended from time to time without the consent of the holders of the Notes or the other Existing T-Mobile Secured Notes to add other Holder Representatives acting as representative for parties holding First Priority Secured Obligations and Junior Priority Secured Obligations. All references to the First Priority Secured Obligations and Junior Priority Secured Obligations in this section of the Description of Notes shall refer only to such First Priority Secured Obligations and Junior Priority Secured Obligations subject to the Intercreditor Agreement and all references in this section of the Description of Notes to the “Secured Obligations” shall refer to such First Priority Secured Obligations and Junior Priority Secured Obligations. By accepting a Note, each holder of a Note will be deemed to have authorized the Trustee to become party to the Intercreditor Agreement and each holder of a Note (including each subsequent holder) will be bound by the terms of the Intercreditor Agreement.

Deutsche Bank Trust Company Americas has been appointed pursuant to the Intercreditor Agreement to serve as the collateral trustee for the benefit of the holders of the First Priority Secured Obligations outstanding from time to time, which include the Original Notes and will include the Exchange Notes pursuant to the Intercreditor Agreement. Deutsche Bank Trust Company Americas has also been appointed pursuant to the Intercreditor Agreement to serve as the collateral trustee for the benefit of the holders of the Junior Priority Secured Obligations.

To secure the payment and performance of the First Priority Secured Obligations, the Issuer and the Secured Guarantors have consented to and the Collateral Trustee has accepted and agreed to hold, in trust under the Intercreditor Agreement for the benefit First Priority Secured Parties, all of its right, title and interest in, to and under the Security Documents and the Collateral granted to the Collateral Trustee thereunder whether now existing or hereafter arising.

Upon receipt by a responsible officer of the Collateral Trustee of a Notice of Event of Default, the Collateral Trustee shall promptly notify the Issuer and all the Holder Representatives of the receipt and contents thereof. So long as such Notice of Event of Default is in effect in accordance with the terms of the Intercreditor Agreement, the Collateral Trustee shall exercise the rights and remedies provided in the Intercreditor Agreement and in the Security Documents subject to the direction of the Controlling Party, as provided in the Intercreditor Agreement. A Notice of Event of Default, once effective, shall remain in effect unless and until it is cancelled as provided in the Intercreditor Agreement.

The Controlling Party shall at all times have the exclusive right, by one or more notices in writing executed and delivered to the Collateral Trustee, to direct the time, method and place of conducting any proceeding for any right or remedy available to the Collateral Trustee, or of exercising any trust or power conferred on the Collateral Trustee, or for the appointment of a receiver, or to direct the taking or the refraining from taking of any action authorized by the Intercreditor Agreement or any Security Document, in each case without any consultation with, or consent of, any other Holder Representative or Secured Party; provided that (i) such direction shall not conflict with any requirement of law or the Intercreditor Agreement or any Security Document, (ii) the Collateral Trustee shall be adequately secured and indemnified as provided in the Intercreditor Agreement and (iii) no Collateral Enforcement Action may be taken unless a Notice of Event of Default is in effect. In the absence of such direction, the Collateral Trustee shall have no duty to take or refrain from taking any action unless explicitly required in the Intercreditor Agreement.

Whether or not any Insolvency Proceeding has been commenced by or against the Issuer or any Secured Guarantor, no Holder Representative or any other Secured Party shall do (and no such Holder Representative or Secured Party (other than the Controlling Party) shall direct the Collateral Trustee to do) any of the following without the consent of the Controlling Party: (i) take any Collateral Enforcement Action or commence, seek to commence or join any other Person in commencing any Insolvency Proceeding; or (ii) object to, contest or take any other action that is reasonably likely to hinder (1) any Collateral Enforcement Action initiated by the Collateral Trustee, (2) any release of Collateral permitted under the Intercreditor Agreement, whether or not done in consultation with or with notice to such Secured Party or (3) any decision by the Controlling Party to forbear or refrain from bringing or pursuing any such Collateral Enforcement Action or to effect any such release.

Beyond its duties (i) as to the custody of the Collateral expressly provided in the Intercreditor Agreement or in any Security Document to which it is a party, (ii) to account to the Secured Parties and the Issuer and the Secured Guarantors for moneys and other property received by it hereunder or under any Security Document to which it is a party and (iii) to exercise reasonable care with respect to any such Collateral in its possession, the Collateral Trustee shall not have any other duty to the Issuer, the Secured Guarantors or to the Secured Parties as to any Collateral or any income thereon or as to the preservation of rights against prior parties or any other rights pertaining thereto; provided that the Collateral Trustee will be deemed to have exercised reasonable care in respect of any Collateral if it exercises the same level of care as it does with respect to collateral held on behalf of third parties in accordance with its standard practices and procedures in effect from time to time.

All moneys which are required by the Intercreditor Agreement or any Security Document to be delivered to the Collateral Trustee or which are received by the Collateral Trustee or any agent or nominee of the Collateral Trustee in respect of the Collateral, whether in connection with the exercise of the remedies provided in the Intercreditor Agreement or any Security Document or otherwise, in each case while a Notice of Event of Default is in effect shall be deposited in a non-interest bearing trust account subject to the exclusive dominion and control of the Collateral Trustee (the “Collateral Account”) and applied in accordance with the terms of the Intercreditor Agreement. Upon the cancellation of all Notices of Event of Default pursuant to the Intercreditor Agreement or the receipt by the Collateral Trustee of any moneys at any time when no Notice of Event of Default is in effect, the Collateral Trustee shall (subject to the terms of the Intercreditor Agreement) cause all funds on deposit in the Collateral Account or otherwise received by the Collateral Trustee to be paid over as promptly as possible to the Issuer or as otherwise directed by the Issuer.

All moneys held by the Collateral Trustee in the Collateral Account while a Notice of Event of Default is in effect and all proceeds of Collateral received in connection with any Collateral Enforcement Action (including as a result of any collection, sale, foreclosure or other realization or distribution of or in respect of any Collateral (whether or not expressly characterized as such)) or in any Insolvency Proceeding (including any adequate protection payments), shall, to the extent available for distribution, be distributed (subject to the provisions of the Intercreditor Agreement) by the Collateral Trustee on each date of distribution (“Distribution Date”) in the following order of priority (with such distributions being made by the Collateral Trustee to the respective Holder Representative for the Secured Parties entitled thereto as provided in the Intercreditor Agreement, and each such Holder Representative shall be responsible for insuring that amounts distributed to it are distributed to its Secured Parties in the order of priority set forth in the Secured Instruments in respect of which it acts as Holder Representative):

First: to the Collateral Trustee or any co-Collateral Trustee or agent of the Collateral Trustee for any unpaid fees, costs, indemnities and expenses and then to any Secured Party which has theretofore advanced or paid, any fees constituting administrative expenses allowable under Section 503(b) of the Bankruptcy Code or any similar provision of any other applicable Bankruptcy Law, an amount equal to the amount thereof so advanced or paid by such Secured Party and for which such Secured Party has not been reimbursed prior to such Distribution Date, and, if such moneys shall be insufficient to pay such amounts and perform in full, then ratably (without priority of any one over any other) to such Secured Parties in proportion to the amounts of such fees advanced by the respective Secured Parties and remaining unpaid on such Distribution Date;

Second: to the First Priority Agent and any Holder Representative ratably for any unpaid fees, costs, indemnities and expenses payable to it in its capacity as a Holder Representative pursuant to the First Priority Debt Documents (to the extent the same constitute First Priority Secured Obligations) and the Existing Sprint Spectrum Indenture;

Third: to any Secured Party which has theretofore advanced or paid any fees other than such administrative expenses, an amount equal to the amount thereof so advanced or paid by such Secured Party and for which such Secured Party has not been reimbursed prior to such Distribution Date, and, if such moneys shall be insufficient to pay such amounts and perform in full, then ratably (without priority of any one over any other) to such Secured Parties in proportion to the amounts of such fees advanced by the respective Secured Parties and remaining unpaid on such Distribution Date;

Fourth: to the holders of First Priority Secured Obligations in an amount equal to the unpaid principal and unpaid interest on and premium and other charges, if any, with respect to the First Priority Secured Obligations and any primary obligations to pay principal, lease payments, guarantee payments, interest, reimbursement obligations,

repurchase amounts in respect of transferred assets, fees, prepayment premiums, liquidated damages or termination payments constituting First Priority Initial Spectrum Obligations, the amount of cash collateral required in respect of outstanding letters of credit, termination amounts in respect of Designated Hedging Obligations that constitute Permitted First Priority Non-Loan Exposure, amounts due in respect of Designated Cash Management Obligations that constitute Permitted First Priority Non-Loan Exposure, amounts due in respect of Designated L/C Facility Obligations that constitute Permitted First Priority Non-Loan Exposure, and interest and fees thereon, in each case, to the extent the same are due and payable, as of such Distribution Date, and, if such moneys shall be insufficient to pay such amounts and perform in full, then ratably to such holders in proportion to the unpaid amounts thereof on such Distribution Date; provided that following the commencement of any Insolvency Proceeding with respect to the Issuer or any Secured Guarantor, solely as among the holders of First Priority Secured Obligations and solely for purposes of this clause “Fourth” and not any other First Priority Debt Documents, in the event the value of the Collateral is not sufficient for the entire amount of Post-Petition Interest on the First Priority Secured Obligations to be allowed under Section 506(a) and (b) of the Bankruptcy Code or any other applicable provision of the Bankruptcy Code or other Bankruptcy Law in such Insolvency Proceeding, the amount of First Priority Secured Obligations of each series of First Priority Secured Obligations shall include only the maximum amount of Post-Petition Interest on the First Priority Secured Obligations allowable under Section 506(a) and (b) of the Bankruptcy Code or any other applicable provision of the Bankruptcy Code or other Bankruptcy Law in such Insolvency Proceeding;

Fifth: to the holders of First Priority Secured Obligations in an amount equal to all other amounts constituting First Priority Secured Obligations, including but not limited to indemnities and payments for increased costs (but excluding amounts referenced in clause “Fourth” above), in each case to the extent the same are due and payable, as of such Distribution Date, and, if such moneys shall be insufficient to pay such amounts and perform in full, then ratably to such holders in proportion to the unpaid amounts thereof on such Distribution Date;

Sixth: after the payment in full of all First Priority Secured Obligations, to the holders of Junior Priority Secured Obligations in an amount equal to all Junior Priority Secured Obligations which have not been paid, including termination amounts in respect of Designated Hedging Obligations that constitute Permitted Junior Priority Non-Loan Exposure, amounts due in respect of Designated Cash Management Obligations that constitute Permitted Junior Priority Non-Loan Exposure and all other Junior Priority Secured Obligations (including but not limited to the unpaid principal and unpaid interest on and premium and other charges, if any, with respect to such Junior Priority Secured Obligations) then outstanding, in each case to the extent then due and payable, as of such Distribution Date, and, if such moneys shall be insufficient to pay such amounts and perform in full, then ratably to such holders in proportion to the unpaid amounts thereof on such Distribution Date; and

Seventh: after the payment in full of all Junior Priority Secured Obligations, any surplus then remaining shall be paid to the Issuer and the Secured Guarantors or their successors or assigns or to whomsoever may be lawfully entitled to receive the same or as a court of competent jurisdiction may direct.

If any Holder Representative or any holder of any Secured Obligations collects or receives any proceeds of such foreclosure, collection or other enforcement that was not, and should have been, applied to the payment of the Secured Obligations in accordance with the preceding paragraph, whether after the commencement of an Insolvency Proceeding or otherwise, such Holder Representative or such holder of Secured Obligations, as the case may be, will forthwith deliver the same to the Collateral Trustee, for the account of the holders of the Secured Obligations, to be applied in accordance with the preceding paragraph. Until so delivered, such proceeds will be held by that Holder Representative or that holder of Secured Obligations, as the case may be, for the benefit of the holders of the Secured Obligations.

Notwithstanding the above, any Guarantor or its subsidiaries may, by written notice to the Collateral Trustee, elect to provide additional collateral to the holders of any series of First Priority Secured Obligations, without providing such additional collateral for the benefit of the holders of any other series of First Priority Secured Obligations so long as such provision is not in violation of any of the First Priority Debt Documents (such collateral, the “Specified Collateral” and such obligations, the “Specified First Priority Secured Obligations”). The proceeds of any Specified Collateral shall be distributed (in the manner set forth above) solely to Secured Parties that are holders of the applicable Specified First Priority Secured Obligations and shall not be distributed to any other Secured Party.

So long as not in violation of any applicable Secured Instrument (as certified by the Issuer or the applicable guarantor to the Collateral Trustee), the Collateral Trustee, the Issuer and the Secured Guarantors may, with the written consent of the Controlling Party or, in the case of Junior Priority Security Documents, the Junior Priority Agent (and, if the Controlling Party or the Junior Priority Agent, as applicable, provides written consent to such amendment (on which the Collateral Trustee shall have no liability for relying), the Collateral Trustee shall), from time to time, enter into (x) written agreements supplemental to the Intercreditor Agreement or to any Security Document for the purpose of adding to, amending, waiving, or otherwise modifying any provisions of the Intercreditor Agreement or any Security Document or changing in any manner the rights or priorities of the Collateral Trustee, the Secured Parties, the Issuer or the Secured Guarantors under the Intercreditor Agreement or thereunder or (y) additional Security Documents securing First Priority Secured Obligations or Junior Priority Secured Obligations; provided that no such supplemental agreement shall (i) amend, modify or waive any provision of the section on amendments in the Intercreditor Agreement without the written consent of each Holder Representative, (ii) reduce the percentages or change the numbers specified in or otherwise amend certain specified definitions or otherwise change the relative rights or priorities of the Secured Parties under the Intercreditor Agreement in respect of payments or Collateral without the written consent of the Controlling Party and the Holder Representative of any series of First Priority Secured Obligations whose rights or priorities could reasonably be expected to be adversely affected thereby, (iii) amend, modify or waive any provision of the section on junior lien intercreditor provisions in the Intercreditor Agreement without the written consent of the Junior Priority Agent if any Junior Priority Debt Obligations are then outstanding, but only if the relative rights or priorities of the Junior Priority Secured Parties in respect of such Junior Priority Debt Obligations could reasonably be expected to be adversely affected thereby, (iv) amend, modify or waive any provision of the Intercreditor Agreement in a manner that is materially adverse to the holders of a particular series of Secured Obligations relative to other Secured Parties of the same Class without the consent of the Holder Representative of such series or (v) amend, modify or waive any provision of the Intercreditor Agreement relating to the Collateral Trustee or alter the duties, rights, privileges, protections, indemnities, immunities or obligations of the Collateral Trustee under the Intercreditor Agreement or under the Trust Security Documents without the written consent of the Collateral Trustee. In the event that there is an amendment, modification or waiver to the First Priority Security Documents in accordance with the terms hereof, then such amendment, modification or waiver shall apply automatically to any comparable provision of the comparable Junior Priority Security Documents without the consent of any Junior Priority Secured Parties and without any action by any Holder Representative in respect of Junior Priority Secured Obligations or any Grantor (as defined in the Collateral Agreement).

Notwithstanding anything else to the contrary in the Intercreditor Agreement, solely with the consent of the Controlling Party or, in the case of the Junior Priority Security Documents, the Junior Priority Agent (and without the consent of any other Secured Party), the Collateral Trustee, the Issuer and any of the Secured Guarantors, at any time and from time to time, may enter into one or more agreements supplemental to the Indenture or to any Security Document, in form satisfactory to the Collateral Trustee, which supplemental agreements may add to, amend, waive, or otherwise modify any provisions of such documents, (i) to add to the covenants of the Issuer or such Secured Guarantor for the benefit of the Secured Parties or to surrender any right or power in the Intercreditor Agreement conferred upon the Issuer or such Secured Guarantor (so long as such addition or surrender applies to all Secured Parties within a Class to the extent applicable); (ii) to mortgage or pledge to the Collateral Trustee, or grant or perfect a security interest in favor of the Collateral Trustee in, any property or assets, including as additional security, for the Secured Obligations; or (iii) to cure any ambiguity, omission or mistake, to correct or supplement any provision in the Intercreditor Agreement or in any Security Document which may be defective or inconsistent with any other provision in the Intercreditor Agreement, to effect administrative changes of a technical or immaterial nature or to make any other provision with respect to matters or questions arising under the Intercreditor Agreement which shall not be inconsistent with any provision hereof; provided that no such supplemental agreement shall amend, modify or waive any provision of the Intercreditor Agreement in a manner that is materially adverse to the holders of a particular series of Secured Obligations relative to other Secured Parties of the same Class without the consent of the Holder Representative of such series.

Upon receipt by the Collateral Trustee (x) from the Controlling Party of written directions to cause the Liens created by the Intercreditor Agreement and by the Security Documents to be released and discharged, provided that the Issuer shall have delivered a certificate of a responsible officer of the Issuer to the Collateral Trustee certifying

that (i) such release of the Collateral is permitted under, and does not violate the terms of, the First Priority Debt Documents and the Junior Priority Debt Documents, if any, and (ii) all conditions precedent to such release of the Collateral have been (or, substantially contemporaneously with such action, shall be) satisfied or (y) of written notices from each Holder Representative stating that the conditions for release in connection with the termination of the applicable First Priority Debt Documents or the applicable Junior Priority Debt Documents, if any, as the case may be, have been satisfied, the security interests created by the Intercreditor Agreement and by the Security Documents shall terminate forthwith and all right, title and interest of the Collateral Trustee in and to the Collateral shall revert to the Secured Guarantors, their successors and assigns.

Upon the sale or other disposition of all the Capital Stock of a Secured Guarantor to any Person (other than the Issuer or another Secured Guarantor) in a transaction permitted (or not prohibited, as the case may be) by the First Priority Debt Documents and the Junior Priority Debt Documents, if any, or upon such Secured Guarantor ceasing to be a guarantor as permitted (or not prohibited, as the case may be) by each such document: (i) such Secured Guarantor and each Subsidiary of such Secured Guarantor which is included in such sale or other disposition or which so ceases to be a guarantor (such Secured Guarantor and each such Subsidiary being referred to in the Intercreditor Agreement as “Included Grantors”) shall cease to be a Secured Guarantor under the Intercreditor Agreement or a party to any Security Document and shall be released automatically from its obligations pursuant thereto and the security interests created by the Security Documents entered into by such Included Grantors in all right, title and interest of such Included Grantors in the Collateral, and the security interests created by the Security Documents in the Capital Stock of such Secured Guarantor, shall terminate automatically, in each case only with respect to such Included Grantors and such Capital Stock.

Upon the sale or other disposition of all or any portion of the Collateral to any Person (other than the Issuer or a Secured Guarantor) in a transaction permitted (or not prohibited, as the case may be) by the First Priority Debt Documents and the Junior Priority Debt Documents, if any, (including pursuant to any consent to such sale and/or release of the security interest in such Collateral pursuant to the terms thereof), the security interests created by the Security Documents in such Collateral shall terminate and such Collateral shall be automatically released from the Lien created by the Security Documents.

Without limiting the preceding two paragraphs, upon receipt by the Collateral Trustee of (i) written notice from the Controlling Party directing the Collateral Trustee to cause the Liens on a portion of the Collateral identified in such notice to be released and discharged and (ii) a certificate of the Issuer confirming that the Collateral identified in such notice in clause (i) above does not constitute all or substantially all of the Collateral and is permitted to be released under the First Priority Debt Documents and Junior Priority Debt Documents, if any, the security interests created by the Security Documents in such Collateral shall terminate forthwith and all right, title and interest of the Collateral Trustee in and to such Collateral shall revert to the Secured Guarantors, their successors and assigns.

Notwithstanding any of the foregoing, if the Collateral Trustee is exercising its rights or remedies with respect to the Collateral under the Security Documents in accordance with the Intercreditor Agreement, and the Collateral Trustee releases any of the Liens securing any Secured Obligations on any part of the Collateral, then all the Liens securing the Secured Obligations on such Collateral shall be automatically, unconditionally and simultaneously released (and the Collateral Trustee shall take any actions reasonably requested by the Issuer to evidence the release of such Liens).

Any and all Liens now existing or hereafter created or arising in favor of any such Junior Priority Secured Party securing or purporting to secure the Junior Priority Secured Obligations, regardless of how acquired, whether by grant, statute, operation of law, subrogation or otherwise, are expressly junior in priority, operation and effect to any and all Liens now existing or hereafter created or arising in favor of the First Priority Secured Parties securing or purporting to secure the First Priority Secured Obligations. No Junior Priority Secured Party shall (i) object to or contest, or support any other Person in contesting or objecting to, in any proceeding (including without limitation, any Insolvency Proceeding), the validity, extent, perfection, priority or enforceability of any security interest in the Collateral granted to, or the allowability of any claims asserted by, any First Priority Secured Party; (ii) prior to the payment and performance in full of the First Priority Secured Obligations, assert, demand, request, plead or otherwise claim the benefit of, any marshalling, appraisal, valuation and any other right that may otherwise be available under any applicable requirement of law with respect to any Collateral to a creditor in its capacity as beneficiary of a junior lien on such Collateral; (iii) in or in connection with any Insolvency Proceeding, file any pleadings or motions, take

any position at any hearing or proceeding of any nature, or otherwise take any action whatsoever, in each case in respect of any of the Collateral, including, without limitation, with respect to the determination of any Liens or claims held by any First Priority Secured Party or the value of any claims of such parties under Section 506(a) of the Bankruptcy Code or otherwise; provided that any such Junior Priority Secured Party may file a proof of claim in an Insolvency Proceeding, subject to the limitations contained in the Intercreditor Agreement and only if consistent with the terms and the limitations on such Junior Priority Secured Party imposed by the Intercreditor Agreement; or (iv) seek relief from the automatic stay or from any other stay in any Insolvency Proceeding or take any action in derogation thereof, in each case in respect of any Collateral, without the prior written consent of the Majority First Priority Secured Parties. Until the First Priority Secured Obligations have been paid and performed in full, none of the Issuer or the Secured Guarantors shall grant or permit any additional Liens on any asset or property of the Issuer or such Secured Guarantor to secure any Junior Priority Secured Obligation unless it has granted, or concurrently therewith grants, a Lien on such asset or property of Issuer or such Secured Guarantor to secure the First Priority Secured Obligations.

Notwithstanding the date, time, method, manner or order of grant, attachment or perfection of any Liens securing any series of First Priority Secured Obligations granted on the Collateral and notwithstanding any provision of the Uniform Commercial Code of any jurisdiction, or any other applicable law or the First Priority Debt Documents or any defect or deficiencies in the Liens securing the First Priority Secured Obligations or any series of First Priority Secured Obligations or any other circumstance whatsoever, each First Priority Secured Party agrees in the Intercreditor Agreement that the Liens securing each series of First Priority Secured Obligations on any Collateral shall be of equal priority.

It is the intention of the First Priority Secured Parties of each series of First Priority Secured Obligations that the holders of such series of First Priority Secured Obligations (and not the holders of any other series of First Priority Secured Obligations) bear the risk of (i) any determination by a court of competent jurisdiction that (x) any of the First Priority Secured Obligations of such series of First Priority Secured Obligations are unenforceable under applicable law or are subordinated to any other obligations (other than another series of First Priority Secured Obligations), (y) any of the First Priority Secured Obligations of such series do not have an enforceable security interest in any of the Collateral securing any other series of First Priority Secured Obligations and/or (z) any intervening security interest exists securing any other obligations (other than another series of First Priority Secured Obligations) on a basis ranking prior to the security interest of such series of First Priority Secured Obligations but junior to the security interest of any other series of First Priority Secured Obligations or (ii) the existence of any collateral for any other series of First Priority Secured Obligations that is not Collateral (any such condition referred to in the foregoing clauses (i) or (ii) with respect to any series of First Priority Secured Obligations, an “Impairment” of such series). In the event of any Impairment with respect to any series of First Priority Secured Obligations, the results of such Impairment shall be borne solely by the holders of such series of First Priority Secured Obligations, and the rights of the holders of such series of First Priority Secured Obligations set forth in the Intercreditor Agreement shall be modified to the extent necessary so that the effects of such Impairment are borne solely by the holders of the series of such First Priority Secured Obligations subject to such Impairment. Additionally, in the event the First Priority Secured Obligations of any series are modified pursuant to applicable law (including, without limitation, pursuant to Section 1129 of the Bankruptcy Code), any reference to such series of First Priority Secured Obligations or the First Priority Debt Documents governing such series of First Priority Secured Obligations shall refer to such obligations or such documents as so modified.

If the Issuer and/or any Secured Guarantor shall become the subject of any Insolvency Proceeding and shall, as debtor(s)-in-possession, move for approval of DIP Financing to be provided by one or more lenders (the “DIP Lenders”) and/or the use of cash collateral under Section 363 of the Bankruptcy Code or any equivalent provision of any other Bankruptcy Law, each First Priority Secured Party (other than any Controlling Party) agrees that it will raise no objection to any such DIP Financing or to the Liens on the Collateral securing the same (“DIP Financing Liens”) or to any use of cash collateral that constitutes Collateral, unless the Controlling Party shall then oppose or object to such DIP Financing or such DIP Financing Liens and/or use of cash collateral (and (i) to the extent that such DIP Financing Liens are senior to the Liens on any such Collateral for the benefit of the Controlling Party, each First Priority Secured Party (other than the Controlling Party) will subordinate its Liens with respect to such Collateral on the same terms as the Liens of the Controlling Party (other than any Liens of any First Priority Secured Parties constituting DIP Financing Liens) are subordinated thereto, and (ii) to the extent that such DIP Financing Liens rank

pari passu with the Liens on any such Collateral granted to secure the First Priority Secured Obligations of the Controlling Party, each First Priority Secured Party (other than the Controlling Party) will confirm the priorities with respect to such Collateral as set forth in the Intercreditor Agreement), in each case so long as (A) the First Priority Secured Parties of each series of First Priority Secured Obligations retain the benefit of their Liens on all such Collateral pledged to the DIP Lenders, including proceeds thereof arising after the commencement of such Insolvency Proceeding, with the same priority vis-a-vis all the other First Priority Secured Parties (other than any Liens of the First Priority Secured Parties constituting DIP Financing Liens) as existed prior to the commencement of the Insolvency Proceeding, (B) the First Priority Secured Parties of each series of First Priority Secured Obligations are granted Liens on any additional or replacement collateral pledged to any First Priority Secured Parties as adequate protection or otherwise in connection with such DIP Financing and/or use of cash collateral, with the same priority vis-a-vis the First Priority Secured Parties (other than any Liens of the First Priority Secured Parties constituting DIP Financing Liens) as set forth in the Intercreditor Agreement, (C) if any amount of such DIP Financing and/or cash collateral is applied to repay any of the First Priority Secured Obligations, such amount is applied pursuant to the Intercreditor Agreement, and (D) if any First Priority Secured Parties are granted adequate protection, including in the form of periodic payments, in connection with such DIP Financing and/or use of cash collateral, the proceeds of such adequate protection are applied pursuant to the Intercreditor Agreement; provided that the First Priority Secured Parties of each series of First Priority Secured Obligations shall have a right to object to the grant of a Lien to secure the DIP Financing over any Collateral subject to Liens in favor of the First Priority Secured Parties of such series of First Priority Secured Obligations or its Holder Representative that shall not constitute Collateral; and provided, further, that the First Priority Secured Parties receiving adequate protection shall not object to any other First Priority Secured Party receiving adequate protection comparable to any adequate protection granted to such First Priority Secured Parties (other than as a provider of DIP Financing) in connection with a DIP Financing and/or use of cash collateral.

Prior to the occurrence of an Investment Grade Event Election, the Issuer will not, and will not permit any Subsidiary Guarantor to, directly or indirectly, create, incur or assume any Lien securing Indebtedness for Borrowed Money upon any Collateral or any Principal Property now owned or hereafter acquired, except Permitted Liens.

Following the occurrence of an Investment Grade Event Election, 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 Post-Release 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 or Permitted Post-Release Liens, as applicable, 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 or Permitted Post-Release Liens, as applicable, 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” or “Permitted Post-Release Liens,” as applicable.

This “Liens” covenant requires only equal and ratable treatment in the application of proceeds of Collateral and does not require that the Trustee or the Collateral Trustee have any ability to control the Collateral or the enforcement of remedies.

Notwithstanding anything to the contrary in this “Liens” covenant, and solely to the extent any Spectrum SPV Equity Interests constitute Excluded Assets pursuant to clause (6) of the definition of “Excluded Assets”, the Issuer will not, and will not permit any “Restricted Subsidiary” under the Credit Agreement to, directly or indirectly, create, incur or assume any Lien on such Spectrum SPV Equity Interests securing Indebtedness unless (i) such Lien is

otherwise permitted under this “Liens” covenant and (ii) a first priority Lien on such Equity Interests (which may be pari passu with such other Lien) is promptly granted to the Collateral Trustee for the benefit of the Secured Parties and any perfection requirements with respect thereto are satisfied within the time periods required by the Credit Agreement.

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:

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, any Security Documents and the Intercreditor Agreement, 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):

Indebtedness under the Credit Agreement, (b) any Wholly-Owned Subsidiary of the Issuer that is not an Excluded Subsidiary and that is not an “Unrestricted Subsidiary” (or the equivalent thereof) under the Credit Agreement becomes an obligor with respect to any capital markets debt securities in an aggregate principal amount in excess of $500.0 million or (c) Parent or any Subsidiary of Parent acquires or creates a Subsidiary that directly or indirectly owns Capital Stock of the Issuer, then the Issuer or Parent, as applicable, will, within 20 Business Days after the date on which it becomes an obligor with respect to any of the foregoing, or reasonably promptly thereafter, (i) cause that newly acquired or created Subsidiary (A) to become a Guarantor of the Notes and execute a supplemental indenture and (B) to execute joinders to the Security Documents or new Security Documents together with any other filings and agreements required by the Security Documents to grant a first-priority Lien on its property and assets, other than Excluded Assets and subject to Permitted Liens, for the benefit of the holders and the Trustee and (ii), if requested by the Trustee, deliver an opinion of counsel reasonably satisfactory to the Trustee.

After the occurrence of an Investment Grade Event Election, with respect to each series of Notes, if 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 and any Indebtedness of an “Unrestricted Subsidiary” (or the equivalent thereof) under the Credit Agreement or Permitted Receivables Financing Subsidiary) that is incurred or issued and outstanding exceeds $2,000.0 million (the “Guarantee Threshold”), then Parent shall cause such of its non-guarantor Subsidiaries that are not Excluded Subsidiaries to, within 60 days, execute and deliver a supplemental indenture providing for a Note Guarantee by such non-guarantor Subsidiaries (each such Note Guarantee, a “Post-Release Event Note Guarantee”) such that the aggregate principal amount of Indebtedness of all other non-guarantor Subsidiaries that are 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 is incurred or issued and outstanding does not exceed the Guarantee Threshold (after giving effect to the provision of Post-Release Event Note Guarantees pursuant to the foregoing); provided that (i) this covenant shall not be applicable to any Indebtedness of any Subsidiary that existed at the time such Person became a Subsidiary of Parent (including any Indebtedness incurred in connection with, or in contemplation of, such Person becoming a Subsidiary, so long as Parent and its Subsidiaries (other than such Person and its Subsidiaries) are not obligors under such Indebtedness), (ii) if the Guarantee Threshold would be exceeded immediately after giving effect to the occurrence of an Investment Grade Event Election, then such Investment Grade Event Election shall be deemed not to have occurred with respect to the release of such Note Guarantees as the Issuer may designate such that the Guarantee Threshold would not be then exceeded and (iii) a Post-Release Event Note Guarantee shall be released to the extent the Guarantee Threshold would not be exceeded after giving effect to such release.

Whether or not required by the rules and regulations of the SEC, so long as any Notes are outstanding, the Issuer 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):

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 the offering memorandum pursuant to which the Original Notes of the applicable series 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). If the combined operations of Parent and its Subsidiaries, excluding the operations of the Issuer and its Subsidiaries and excluding Cash Equivalents, would, if held by a single Subsidiary of the Issuer, constitute a Significant Subsidiary of the Issuer, then the quarterly and annual financial information required by the preceding paragraphs will include a reasonably detailed presentation, either on the face of the financial statements or in the footnotes thereto, and in Management’s Discussion and Analysis of Financial Condition and Results of Operations, of the financial condition and results of operations of the Issuer and its Subsidiaries separate from the financial condition and results of operations of Parent and its other Subsidiaries; provided, however, that the requirements of this paragraph shall not apply if Parent or the Issuer files with the SEC the reports referred to in clauses (1) and (2) of the first paragraph of this covenant, and any such report contains the information required in this paragraph.

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 or the Issuer 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.

Any such reports delivered or filed by the Issuer with 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).

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

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 and subject to the terms of the Intercreditor Agreement, 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 Security Documents at the request or direction of any holders of Notes unless such holders have offered to the Trustee indemnity or security satisfactory to it against any loss, liability or expense. Subject to the Intercreditor Agreement, 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:

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 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, the Intercreditor Agreement, the Security Documents 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.

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 the related Security Documents with respect thereto and all obligations of the Guarantors discharged with respect to their Note Guarantees and the Security Documents with respect to such series (“Legal Defeasance”) and cure all then existing Defaults and Events of Defaults except for:

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 “—Repurchase at the Option of Holders” and under the caption “—Certain Covenants” (other than the covenant described under the caption “—Certain Covenants—Merger, Consolidation or Sale of Assets”) (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 (8) (in the case of clauses (7) and (8), only with respect to the Issuer’s Subsidiaries) and clauses (9) through (10) 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:

Except as provided in the next two succeeding paragraphs, the Intercreditor Agreement, the Security Documents, 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 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, the Notes of such series).

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

Notwithstanding the foregoing, without the consent of the holders of at least 66²∕3% in aggregate principal amount of the Notes of a series then outstanding, no amendment or waiver may make any change in any Security Document, the Intercreditor Agreement or the provisions in the Indenture dealing with Collateral or application of trust proceeds of the Collateral with the effect of releasing the Liens securing the Obligations in respect of the Notes of such series on all or substantially all of the Collateral.

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

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, “—Repurchase at the Option of Holders” or “—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 to institute suit for the enforcement of any payment on or with respect to such holder’s Notes.

The applicable Indenture will be discharged and will cease to be of further effect as to the Notes of a series issued thereunder, when:

In addition, the Issuer must deliver to the Trustee (a) an officer’s certificate, stating that all conditions precedent set forth in clauses (1) through (3) above 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 clause (3) above have been satisfied.

The Indenture, the Intercreditor Agreement, the Security Documents, the Notes and the Note Guarantees are (with respect to the Original Notes) and will be (with respect to the Exchange Notes) governed by the laws of the State of New York.

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.

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