Forward-looking statements in this prospectus, any accompanying prospectus supplement or the documents incorporated by reference speak only as of the date of this prospectus, the applicable prospectus supplement or the applicable document incorporated by reference (or such earlier date as may be specified in the applicable prospectus supplement or other 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.

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.

distribution of our common stock to engage in market-making activities with respect to our common stock. These restrictions may affect the marketability of our common stock and the ability of any person or entity to engage in market-making activities with respect to our common stock.

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

This prospectus relates to the resale of notes of T-Mobile USA, Inc. (“T-Mobile USA” or “Issuer”), a wholly-owned subsidiary of T-Mobile US, Inc. (“Parent” or the “Company”), including 4.000% Senior Notes due 2022-1 in an aggregate principal amount of up to $1,000,000,000 (the “2022 notes”), 4.500% Senior Notes due 2026-1 in an aggregate principal amount of up to $1,000,000,000 (the “2026 notes”), 5.375% Senior Notes due 2027-1 in an aggregate principal amount of up to $1,250,000,000 (the “2027 notes”) and 4.750% Senior Notes due 2028-1 in an aggregate principal amount of up to $1,500,000,000 (the “2028 notes” and collectively with the 2022 notes, the 2026 notes and the 2027 notes, the “notes” and each a “series” of notes). We will not receive any of the proceeds from the sale of the notes by the selling securityholder.

The 2022 notes bear interest at a rate of 4.000% per year and mature on April 15, 2022. The 2026 notes bear interest at a rate of 4.500% per year and mature on February 1, 2026. The 2027 notes bear interest at a rate of 5.375% per year. As a result of an amendment to the indenture governing the 2027 notes, the 2027 notes mature on April 15, 2022. The 2028 notes bear interest at a rate of 4.750% per year and mature on February 1, 2028. The Issuer pays interest on the 2022 notes and 2027 notes on each April 15 and October 15 of each year. The Issuer pays interest on the 2026 notes and 2028 notes on February 1 and August 1 of each year.

The notes of each series will be redeemable, in whole or in part, at any time on or after the dates and at the redemption prices specified in the applicable “Description of Notes” section of this prospectus under “—Optional Redemption” plus accrued and unpaid interest to, but not including, the redemption date. The Issuer also may redeem the notes of each series prior to the dates specified in the applicable “Description of Notes” section of this prospectus under “—Optional Redemption” at a specified redemption price plus an applicable premium, plus accrued and unpaid interest to, but not including, the redemption date.

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

The notes are senior unsecured obligations of the Issuer and rank equally with all of the other senior unsecured debt and future senior unsecured debt of the Issuer. The notes are unconditionally guaranteed on a senior unsecured basis by Parent and certain subsidiary guarantors.

The notes are not listed on any securities exchange or included in any automated dealer quotation system.

As used in this prospectus, unless otherwise noted or the context requires otherwise:

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 agreements, 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 any 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 June 30, 2020, assuming that we had completed the Incremental Amendment, we also would have had $5.5 billion available for borrowings under the Revolving Credit Facility. 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 significant indebtedness could adversely affect our business, financial condition and operating results, and senior creditors would have a secured claim to any collateral securing the debt owed to them.”

The notes and the guarantees are general unsecured, unsubordinated obligations ranking effectively junior in right of payment to all existing and future secured debt of the Issuer and of each guarantor, including the Existing T-Mobile Secured Notes and borrowings under the Credit Agreement, to the extent of the value of the collateral securing such debt, and are structurally subordinated to any existing or future indebtedness, any future preferred stock and other liabilities of the Issuer’s non-guarantor subsidiaries. The notes also permit us to incur certain additional secured debt.

If the Issuer or a guarantor is declared bankrupt, becomes insolvent or is liquidated or reorganized, any secured debt of the Issuer or of that guarantor, including borrowings under the Credit Agreement, will be entitled to be paid in full from the Issuer’s assets or the assets of the guarantor, as applicable, securing that debt before any payment may be made with respect to the notes or the guarantees.

Holders of the notes will participate ratably in any remaining assets with all holders of the Issuer’s and each guarantor’s unsecured indebtedness that is not by its terms subordinated to the notes, including all of the Issuer’s and each guarantor’s other general creditors, based upon the respective amounts owed to each holder or creditor. In any of the foregoing events, there may not be sufficient assets to pay the indebtedness and other obligations owed to secured creditors and the amounts due on the notes. As a result, holders of the notes would likely receive less, ratably, than holders of secured indebtedness. It is possible that there will be no assets from which claims of holders of the notes can be satisfied.

As of June 30, 2020, we had outstanding indebtedness with a carrying value of approximately $72.7 billion, excluding letter of credit obligations, including $27.0 billion in aggregate principal amount of outstanding secured indebtedness. Our secured indebtedness consisted of $23.0 billion in aggregate principal amount of Existing T-Mobile Secured Notes and $4.0 billion in aggregate principal amount of secured term indebtedness under the Credit Agreement. In addition, we had $13.1 billion in aggregate principal amount of outstanding unsecured indebtedness under the Existing T-Mobile Unsecured Notes and the notes (excluding $4.0 billion in aggregate principal amount of Existing T-Mobile Unsecured Notes called for redemptions subsequent to June 30, 2020), $19.8 billion in aggregate principal amount of outstanding unsecured indebtedness under the Existing Sprint Unsecured Notes (excluding $1.5 billion in aggregate principal amount of Existing Sprint Unsecured Notes that matured on August 15, 2020) and approximately $3.1 billion in tower obligations. In addition, as of June 30, 2020, an aggregate $5.0 billion in aggregate principal amount of Existing Sprint Spectrum-Backed Notes was outstanding and up to $2.0 billion remained available for issuance under the Sprint Spectrum Note Facility. Assuming that on June 30, 2020, we had completed the Incremental Amendment, we also would have had $5.5 billion of revolving borrowings available on a secured basis under the Credit Agreement. The notes are effectively subordinated to the secured debt to the extent of the value of the assets constituting collateral securing this secured debt.

In addition, creditors of current and future subsidiaries of the Issuer that do not guarantee the notes would have claims, with respect to the assets of those subsidiaries that rank structurally senior to the notes. As of June 30, 2020, our non-guarantor subsidiaries had approximately $9.9 billion of total assets and approximately $7.2 billion of outstanding indebtedness and tower obligations. In the event of any distribution or payment of assets of such subsidiaries in any dissolution, winding up, liquidation, reorganization, or other bankruptcy proceeding, the claims of those creditors must be satisfied prior to making any such distribution or payment to the Issuer in respect of direct or indirect equity interests in such subsidiaries. Certain subsidiaries of the Issuer (such as special purpose entities, a reinsurance subsidiary and immaterial subsidiaries) do not guarantee the notes. See “—The Note Guarantees” in each “Description of Notes” section of this prospectus.

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 Senior Notes, other debt agreements and other agreements we may enter into in the future. Specifically, under the Revolving Credit Facility under the 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 debt or repay all indebtedness in a timely manner or on favorable or commercially reasonable terms, or at all. If we are unable to satisfy financial covenants or to generate sufficient cash to timely repay debt, our lenders could accelerate the maturity of some or all of our outstanding indebtedness. As a result, we may need to refinance all or a portion of our remaining existing indebtedness prior to its maturity. We also expect to need to refinance certain indebtednes. 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 favorable

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), and we may be the subject of such inquires or offers in the future, and may engage in discussions or negotiations regarding such inquiries or offers that may ultimately lead to a transaction. The indentures governing the T-Mobile Secured Notes, the T-Mobile Unsecured Notes, the notes, the Existing Sprint Spectrum-Backed Notes and certain of the Existing Sprint Unsecured Notes provide that, upon the occurrence of certain change of control triggering events, which change of control triggering events include a change of control combined with certain ratings downgrades or withdrawals as described further under “—Repurchase at the Option of Holders—Change of Control Triggering Event” in each “Description of Notes” section of this prospectus, the Issuer will be required to offer to repurchase all outstanding Existing T-Mobile Secured Notes, all outstanding Existing T-Mobile Unsecured Notes, the notes, all of the Existing Sprint Spectrum-Backed Notes and certain of the Existing Sprint Unsecured Notes at 101% of the principal amount thereof plus accrued and unpaid interest, if any, to the date of repurchase. In addition, any such change of control triggering event is expected to cause an event of default under the Credit Agreement, entitling the lenders to declare all amounts outstanding thereunder to be immediately due and payable. Such a change of control would also trigger repayments with respect to our securitization transactions and capital leases. We may not have access to sufficient funds at the time of the change of control triggering event to make the required repurchases of the Existing T-Mobile Secured Notes, the Existing T-Mobile Unsecured Notes, the notes, the Existing Sprint Spectrum-Backed Notes and certain of the Existing Sprint Unsecured Notes, and repay outstanding amounts under the Credit Agreement or contractual restrictions may not allow such repurchases or repayments. However, not all change of control transactions would trigger our repurchase obligations. Specifically, the change of control provisions in the indentures governing the Existing T-Mobile Secured Notes, the Existing T-Mobile Unsecured Notes, the notes, the Existing Sprint Spectrum-Backed Notes and certain of the Existing Sprint Unsecured Notes will not trigger our repurchase obligations unless both (i) such a transaction constitutes a “Change of Control” under the relevant indenture and (ii) the Change of Control is accompanied or followed by a downgrade or withdrawal of the rating of the notes in the manner and in the time frame described under “—Repurchase at the Option of Holders—Change of Control Triggering Event” in the applicable “Description of Notes” section of this prospectus. 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 Senior Notes as required under the respective indentures would result in defaults under such indentures or breach of such noteholder agreement, in addition to any events of default under the Credit Agreement resulting from a change of control triggering event thereunder, any of which could have material adverse consequences for us and the holders of the notes. Any such event of default would likely trigger an event of default on other outstanding or future indebtedness.

The indentures governing the Senior Notes, as well as the Credit Agreement and other financing arrangements, impose significant operating and financial restrictions on us. These restrictions, subject in certain cases to customary baskets, exceptions and incurrence-based ratio tests, may limit our or our restricted subsidiaries’ ability to engage in some transactions, including the following:

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 Senior 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 could have a material adverse effect on our business, financial condition, and operating results.

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

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

If a guarantee is voided as a fraudulent conveyance or found to be unenforceable for any other reason, you will not have a claim against that obligor and will only be our creditor or that of any guarantor whose obligation was not set aside or found to be unenforceable. In addition, the loss of a guarantee will constitute an event of default under the indentures relating to the Senior Notes, and may constitute an event of default under 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 have the ability to pay any such amounts.

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

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

As of June 30, 2020, we had approximately $55.8 billion in aggregate principal amount of outstanding indebtedness under the Senior Notes (excluding $4.0 billion in aggregate principal amount of Existing T-Mobile Unsecured Notes called for redemptions subsequent to June 30, 2020 and $1.5 billion in aggregate principal amount of Existing Sprint Unsecured Notes that matured on August 15, 2020). The market price of the notes could decline as a result of our, or existing investors’ sales of the Issuer’s debt securities in the market after this offering, or the perception that such sales could occur. These sales, or the possibility that these sales may occur, also might make it more difficult for the Issuer to sell other debt securities in the future at a time and on terms that it deems appropriate.

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

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 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.

indebtedness. Our secured indebtedness consisted of $23.0 billion in aggregate principal amount of Existing T-Mobile Secured Notes and $4.0 billion in aggregate principal amount of secured term indebtedness under the Credit Agreement. In addition, we had $13.1 billion in aggregate principal amount of outstanding unsecured indebtedness under the Existing T-Mobile Unsecured Notes (excluding $4.0 billion in aggregate principal amount of Existing T-Mobile Unsecured Notes called for redemptions subsequent to June 30, 2020), $19.8 billion in aggregate principal amount of outstanding unsecured indebtedness under the Existing Sprint Unsecured Notes (excluding $1.5 billion in aggregate principal amount of Existing Sprint Unsecured Notes that matured on August 15, 2020) and approximately $3.1 billion in tower obligations relating to the transactions contemplated by the Towers Transaction Agreements, the Phoenix Towers Transaction Agreements and the Sprint Towers Transaction Agreements. Assuming that on June 30, 2020, we had completed the Incremental Amendment, we also would have had $5.5 billion of revolving borrowings available on a secured basis under the Credit Agreement.

In addition, as of June 30, 2020, an aggregate principal amount of $5.0 billion of Existing Sprint Spectrum-Backed Notes was outstanding and up to $2.0 billion remained available for issuance under the Sprint Spectrum Note Facility. The Existing Sprint Spectrum Note Entities own a pool of 2.5 GHz and 1.9 GHz spectrum which has been pledged to secure indebtedness under the Sprint Spectrum Note Facility. This spectrum will not secure the notes.

As of June 30, 2020, our non-guarantor subsidiaries had approximately $9.9 billion of total assets and approximately $7.2 billion of outstanding indebtedness and tower obligations.

The notes are guaranteed by Parent, all of Issuer’s Domestic Restricted Subsidiaries that are Wholly-Owned Subsidiaries (other than Existing Sprint Spectrum Note Entities, Designated Tower Entities, Immaterial Subsidiaries and the Reinsurance Entity), Issuer’s Restricted Subsidiaries that guarantee any Specified Issuer Indebtedness, and any future Subsidiary of Parent that directly or indirectly owns equity interests of Issuer. These Note Guarantees are joint and several obligations of the Guarantors. The obligations of each Guarantor under its Note Guarantee are limited as necessary to prevent that Note Guarantee from constituting a fraudulent conveyance under applicable law. Each guarantee of the notes by a Guarantor:

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

As of the date of this prospectus, all of Issuer’s Subsidiaries other than certain special purpose entities are “Restricted Subsidiaries.” However, under the circumstances described below under the caption “—Certain Covenants—Designation of Restricted and Unrestricted Subsidiaries,” Issuer will be permitted to designate certain of its Subsidiaries as “Unrestricted Subsidiaries.” Issuer’s Unrestricted Subsidiaries will not be subject to many of the restrictive covenants in the indenture. Issuer’s Unrestricted Subsidiaries will not guarantee the notes.

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

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

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

Issuer may issue additional notes of any series from time to time, and such additional notes of such series may be issued under the base indenture as supplemented either by the supplemental indenture for such series of notes or one or more other supplemental indentures. Any issuance of additional notes is subject to all of the covenants in the indenture, including the covenant described below under the caption “—Certain Covenants—Incurrence of Indebtedness and Issuance of Disqualified Stock and Preferred Stock.” The notes of any series and any additional notes of such series subsequently issued will be treated as a single series for all purposes under the indenture, including, without limitation, waivers, amendments, redemptions and offers to purchase. Issuer issued the notes in

minimum denominations of $2,000 and integral multiples of $1,000. The 2022 notes and the 2027 notes will mature on April 15, 2022. As a result of an amendment to the indenture governing the 2027 notes, such notes will become due in 2022 notwithstanding their series name.

Interest on the 2022 notes accrues at the rate of 4.000% per annum and interest on the 2027 notes accrues at the rate of 5.375% per annum, and interest on each series of notes is payable semiannually in arrears on April 15 and October 15. Issuer will make each interest payment to the holders of record on the immediately preceding April 1 and October 1.

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

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

If a holder of a definitive note has given wire transfer instructions to Issuer and Issuer is the paying agent, Issuer will pay all principal, interest and premium, if any, on that holder’s notes in accordance with those instructions until given written notice to the contrary. All other payments on the notes will be made at the Corporate Trust Office of the Trustee, unless Issuer elects to make interest payments by checks 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 and registrar. Issuer may change the paying agent or registrar without prior notice to the holders of the notes, and Issuer or any of its Subsidiaries may act as paying agent or registrar.

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

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

At any time on or after March 16, 2022 (the date that is 30 days prior to the scheduled maturity date of the 2022 notes), Issuer may redeem all or a part of the 2022 notes, upon not less than 10 nor more than 60 days’ notice (in the case of redemptions upon less than 30 days’ notice, if any Global Notes are outstanding, subject to the ability of DTC to process such redemption on the date specified in such notice), at a redemption price equal to 100% of the

principal amount of 2022 notes redeemed plus accrued and unpaid interest to, but not including, the date of redemption, subject to the rights of holders of 2022 notes on the relevant record date to receive interest due on the relevant interest payment date for periods prior to such date of redemption.

At any time prior to March 16, 2022 (the date that is 30 days prior to the scheduled maturity date of the 2022 notes), Issuer may also redeem all or a part of the 2022 notes, upon not less than 10 nor more than 60 days’ notice (in the case of redemptions upon less than 30 days’ notice, if any Global Notes are outstanding, subject to the ability of DTC to process such redemption on the date specified in such notice), at a redemption price equal to 100% of the principal amount of 2022 notes redeemed plus the Applicable Premium for the 2022 notes as of, and accrued and unpaid interest to, but not including, the date of redemption, subject to the rights of holders of 2022 notes on the relevant record date to receive interest due on the relevant interest payment date for periods prior to such date of redemption.

Unless Issuer defaults in the payment of the redemption price, interest will cease to accrue on the 2022 notes or portions thereof called for redemption on the redemption date.

At any time prior to April 15, 2020, Issuer may on any one or more occasions redeem up to 40% of the aggregate principal amount of the 2027 notes issued under the applicable indenture at a redemption price of 105.375%, plus accrued and unpaid interest to, but not including, the redemption date, with the net cash proceeds of one or more sales of Equity Interests (other than Disqualified Stock) of Issuer or contributions to Issuer’s common equity capital made with the net cash proceeds of one or more sales of Equity Interests (other than Disqualified Stock) of Parent; provided that:

At any time prior to April 15, 2022, Issuer may also redeem all or a part of the 2027 notes, upon not less than 10 nor more than 60 days’ notice (in the case of redemptions upon less than 30 days’ notice, if any Global Notes are outstanding, subject to the ability of DTC to process such redemption on the date specified in such notice), at a redemption price equal to 100% of the principal amount of 2027 notes redeemed plus the Applicable Premium for the 2027 notes as of, and accrued and unpaid interest to, but not including, the date of redemption, subject to the rights of holders of 2027 notes on the relevant record date to receive interest due on the relevant interest payment date for periods prior to such date of redemption.

Unless Issuer defaults in the payment of the redemption price, interest will cease to accrue on the 2027 notes or portions thereof called for redemption on the redemption date.

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

Issuer is not required to make mandatory redemption payments with respect to the 2022 notes or 2027 notes.

If a Change of Control Triggering Event occurs with respect to any series of notes, each holder of notes of such series will have the right to require Issuer to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 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, Issuer will offer a Change of Control Payment in cash equal to 101% of the aggregate principal amount of notes repurchased plus accrued and unpaid interest on the notes repurchased to, but not including, the date of purchase, subject to the rights of holders of notes on the relevant record date to receive interest due on the relevant interest payment date for periods prior to such repurchase date (the

“Change of Control Payment”). Within 30 days following any Change of Control Triggering Event, Issuer will send a notice (the “Change of Control Offer”) to each holder of notes to which such Change of Control Triggering Event applies and the trustee describing the transaction or transactions and identify the ratings decline that together constitute the Change of Control Triggering Event and offering to repurchase the notes of such series on the Change of Control Payment Date specified in the notice, which date will be no earlier than 10 days and no later than 60 days from the date such notice is sent (the “Change of Control Payment Date”), pursuant to the procedures required by the indenture and described in such notice. Issuer will comply with the requirements of Rule 14e-1 under the 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, Issuer will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Change of Control Triggering Event provisions of the indenture by virtue of such compliance. In connection with the tender of any notes with respect to a Change of Control Triggering Event, the tendering holder shall provide good title to the notes, free and clear of all liens and encumbrances, and shall represent and warrant that such holder is presenting good title, free and clear of all liens and encumbrances, and such other representations and warranties as are customary.

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

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

The provisions described above that require Issuer to make a Change of Control Offer following a Change of Control Triggering Event will be applicable whether or not any other provisions of the indenture are applicable. Except as described above with respect to a Change of Control Triggering Event, the indenture does not contain provisions that permit the holders of the notes to require, or otherwise provide, that Issuer repurchase or redeem the notes in the event of a takeover, recapitalization or similar transaction.

Notwithstanding the foregoing, Issuer will not be required to make a Change of Control Offer with respect to 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 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 Issuer purchases all of the notes of such series held by such holders, Issuer will have the right, upon not less than 10 nor more than 60 days’ notice (in the case of redemptions upon less than 30 days’ notice, subject to the ability of DTC to process such redemption on the date specified in such notice), given not more than 30 days following the purchase pursuant to the Change of Control Offer described above, to redeem all of the notes of such series that remain outstanding following such purchase at a redemption price equal

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

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

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

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

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

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

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

An amount equal to any Net Proceeds from Asset Sales that are not applied or invested as provided in the third paragraph of this covenant will constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds

exceeds $100.0 million, within 20 days thereof, Issuer shall apply the entire aggregate amount of unutilized Excess Proceeds (not only the amount in excess of $100.0 million) to make an offer (an “Asset Sale Offer”) to all holders of notes and all holders of other Indebtedness that is pari passu with the notes containing provisions requiring Issuer to make an offer to purchase or redeem with the proceeds of sales of assets to purchase the maximum principal amount of notes and purchase or redeem such other pari passu Indebtedness that may be purchased or redeemed out of the Excess Proceeds. The offer price in any Asset Sale Offer will be equal to 100% of the principal amount of the notes and such other pari passu Indebtedness that may be purchased or redeemed with Excess Proceeds, plus accrued and unpaid interest, if any, to, but not including, the date of consummation of the purchase, and will be payable in cash. If any Excess Proceeds remain after consummation of an Asset Sale Offer, Issuer and its Restricted Subsidiaries may use those Excess Proceeds for any purpose not otherwise prohibited by the indenture. If the aggregate principal amount of notes and other pari passu Indebtedness tendered in response to such Asset Sale Offer exceeds the amount of Excess Proceeds, the trustee shall select the notes and Issuer will select such other pari passu Indebtedness to be purchased or redeemed on a pro rata basis unless otherwise required by law or applicable stock exchange or depositary requirements. Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero.

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

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

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

No notes of $2,000 or less can be redeemed in part. Notices of redemption will be sent electronically or mailed by first class mail at least 10 but not more than 60 days before the redemption date to each holder of notes to be redeemed at its registered address, except that redemption notices may be sent more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the notes of a series or a satisfaction and discharge of the indenture with respect to such series. Except as otherwise set forth in the provisions described under the caption “—Repurchase at the Option of Holders—Change of Control Triggering Event,” any such redemption may, at Issuer’s discretion, be subject to one or more conditions precedent. In addition, if such redemption or notice is subject to satisfaction of one or more conditions precedent, such notice shall state that, in Issuer’s discretion, the redemption date may be delayed until such time as any or all such conditions shall be satisfied (or waived by 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 Issuer in its sole discretion) by the redemption date (whether the original redemption date or the redemption date so delayed).

If any note is to be redeemed in part only, the notice of redemption that relates to that note will state the portion of the principal amount of that note that is to be redeemed. If in definitive form a new note in principal amount equal

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

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

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

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

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

As of June 30, 2020, the amount calculated pursuant to clause (3)(a)–(g) above (the “RP Basket”), was approximately $102.9 billion.

The preceding provisions will not prohibit:

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

Issuer will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee or otherwise become directly or indirectly liable, contingently or otherwise, with respect to (collectively, “incur”) any Indebtedness (including Acquired Debt), and Issuer will not issue any Disqualified Stock and will not permit any of its Restricted Subsidiaries to issue any shares of Preferred Stock; provided, however, that Issuer may incur Indebtedness (including Acquired Debt) or issue Disqualified Stock and the Subsidiary Guarantors may incur Indebtedness (including Acquired Debt) or issue Preferred Stock, if the Debt to Cash Flow Ratio for Issuer’s most recently ended four full fiscal quarters for which internal financial statements are available immediately preceding the date on which such additional Indebtedness is incurred or such Disqualified Stock or such Preferred Stock is issued, as the case may be, would have been no greater than 6.00 to 1.00, determined on a pro forma basis (including a pro forma application of the net proceeds therefrom), as if the additional Indebtedness had been incurred or the Disqualified Stock or the Preferred Stock had been issued, as the case may be, at the beginning of such four-quarter period.

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

The Existing Sprint Spectrum Notes are deemed to be outstanding pursuant to clause (1) above and reduce the amount of Indebtedness otherwise permitted to be incurred thereunder.

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

For purposes of (x) determining compliance with this “Incurrence of Indebtedness and Issuance of Disqualified Stock and Preferred Stock” covenant, in the event that an item of proposed Indebtedness meets the criteria of more than one of the categories of Permitted Debt described in clauses (1) through (25) above, or is entitled to be incurred pursuant to the first paragraph of this covenant, Issuer will be permitted to classify all or a portion of such item of Indebtedness on the date of its incurrence, or later reclassify all or a portion of such item of Indebtedness, in any manner that complies with this covenant; provided, however that Indebtedness outstanding under the Term Loan Credit Agreement on the Issue Date shall be deemed to have been incurred under clause (1) above and (y) determining the amount of Indebtedness that may be incurred pursuant to clause (1)(a)(y) of the definition of Permitted Debt, Issuer may elect, pursuant to an officers’ certificate delivered to the trustee, to treat all or any portion of the commitment under any Indebtedness (and any refinancing with respect thereto) as being incurred at such time, in which case any subsequent incurrence of Indebtedness under such commitment or refinancing, as the case may be, shall not be deemed, for purposes of this calculation, to be an incurrence at such subsequent time. The accrual of interest, the accretion or amortization of original issue discount, the payment of interest on any Indebtedness in the

form of additional Indebtedness with the same terms, the reclassification of Preferred Stock as Indebtedness due to a change in accounting principles or the application thereof, and the payment of dividends on Disqualified Stock in the form of additional shares of the same class of Disqualified Stock will not be deemed to be an incurrence of Indebtedness or an issuance of Disqualified Stock for purposes of this covenant. Notwithstanding any other provision of this covenant, the maximum amount of Indebtedness that Issuer or any Restricted Subsidiary may incur pursuant to this covenant shall not be deemed to be exceeded solely as a result of fluctuations in exchange rates or currency values, and in no event shall the reclassification of any lease or other liability as indebtedness due to a change in accounting principles after the Closing Date be deemed to be an incurrence of Indebtedness. In determining the amount of Indebtedness outstanding under one of the clauses above, the outstanding principal amount of any particular Indebtedness of any Person shall be counted only once and any obligation of such Person or any other Person arising under any guarantee, Lien, letter of credit or similar instrument supporting such Indebtedness shall be disregarded so long as it is permitted to be incurred by the Person or Persons incurring such obligation.

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

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

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

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

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

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

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

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

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

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

If (a) Issuer or any of Issuer’s Domestic Restricted Subsidiaries acquires or creates another Domestic Restricted Subsidiary (and such Subsidiary is a Wholly-Owned Subsidiary and is not a Designated Tower Entity, the Reinsurance Entity, an Immaterial Subsidiary or (so long as the aggregate principal amount of Existing Sprint Spectrum Notes does not exceed the Existing Sprint Spectrum Program Cap) an Existing Sprint Spectrum Subsidiary) after the Series Issue Date or (b) any Restricted Subsidiary of Issuer guarantees any Specified Issuer Indebtedness of Issuer after the Series Issue Date or (c) Parent or any Subsidiary of Parent acquires or creates a Subsidiary that directly or indirectly owns Equity Interests of Issuer, then Issuer or Parent, as applicable, will cause that newly acquired or created Domestic Restricted Subsidiary, Restricted Subsidiary or Subsidiary of Parent to become a guarantor of the notes and execute a supplemental indenture and, if requested by the trustee, deliver an opinion of counsel reasonably satisfactory to the trustee within 10 Business Days after the date on which it was acquired or created or guarantees such Specified Issuer Indebtedness, as applicable, or reasonably promptly thereafter.

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

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

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

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

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

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

If the SEC will not accept Parent’s or Issuer’s filings for any reason, Parent or Issuer will post the reports referred to in the preceding paragraphs on its website, on intralinks.com or another website within the time periods that would apply if Parent were required to file those reports with the SEC (including all applicable extension periods). If (i) Issuer has designated any of its Subsidiaries as Unrestricted Subsidiaries or (ii) the combined operations of Parent and its Subsidiaries, excluding the operations of Issuer and its Restricted Subsidiaries and excluding cash and Cash Equivalents, would, if held by a single Unrestricted Subsidiary of Issuer, constitute a Significant Subsidiary of Issuer, then the quarterly and annual financial information required by the preceding paragraphs will include a reasonably detailed presentation, either on the face of the financial statements or in the footnotes thereto, and in Management’s Discussion and Analysis of Financial Condition and Results of Operations, of (A) in the case of (i) above, the financial condition and results of operations of Parent, Issuer and its Restricted Subsidiaries separate from the financial condition and results of operations of the Unrestricted Subsidiaries of Issuer and (B) in the case of (ii) above, the financial condition and results of operations of Issuer and its Restricted Subsidiaries separate from the financial condition and results of operations of Parent and its other Subsidiaries; provided, however, that the requirements of this paragraph shall not apply if Parent or Issuer files with the SEC the reports referred to in clauses (1) and (2) of the first paragraph of this covenant, and any such report contains the information required in this paragraph.

For so long as any notes remain outstanding, if at any time they are not required to file with the SEC the reports required by the preceding paragraphs, Issuer and the Guarantors will furnish to the holders of notes and to securities analysts and prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act of 1933, as amended (the “Securities Act”).

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

Subject to certain limitations, the holders of a majority in aggregate principal amount of the then outstanding notes of 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 interest or premium, if any, on, or the principal of, the notes of such series.

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

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

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

In the case of any Event of Default occurring by reason of any willful action (or inaction) taken (or not taken) by or on behalf of Issuer with the intention of avoiding payment of the premium that Issuer would have had to pay if Issuer then had elected to redeem the notes pursuant to the optional redemption provisions of the indenture, an equivalent premium will also become and be immediately due and payable to the extent permitted by law upon the acceleration of the notes of such series.

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

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

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

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

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 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 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 preceding, without the consent of any holder of notes, Issuer, the Guarantors and the trustee may amend or supplement the applicable indenture, the notes of any 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.

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

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

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

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

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

The notes were initially evidenced by one or more definitive notes. Prior to the offer and sale of the notes under this prospectus, we anticipate the notes will be issued in registered, global form (“Global Notes”). The Global Notes will be deposited upon issuance with the trustee as custodian for DTC and registered in the name of DTC or its nominee, in each case, for credit to an account of a direct or indirect participant in DTC as described below.

Except as set forth below, the Global Notes may be transferred, in whole and not in part, only to another nominee of DTC or to a successor of DTC or its nominee. Beneficial interests in the Global Notes may not be exchanged for definitive notes in registered certificated form (“Certificated Notes”) except in the limited circumstances described below. See “—Exchange of Global Notes for Certificated Notes.” Except in the limited circumstances described below, owners of beneficial interests in the Global Notes will not be entitled to receive physical delivery of such notes in certificated form.

Transfers of beneficial interests in the Global Notes will be subject to the applicable rules and procedures of DTC and its direct or indirect participants (including, if applicable, those of Euroclear System (“Euroclear”) and Clearstream Banking, S.A. (“Clearstream”)), which may change from time to time.

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

DTC has advised Issuer that DTC is a limited-purpose trust company created to hold securities for its participating organizations (collectively, the “Participants”) and to facilitate the clearance and settlement of transactions in those securities between the Participants through electronic book-entry changes in accounts of its Participants. The Participants include securities brokers and dealers (including the underwriters), banks, trust companies, clearing corporations and certain other organizations. Access to DTC’s system is also available to other entities such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a Participant, either directly or indirectly (collectively, the “Indirect Participants”). Persons who are not Participants may beneficially own securities held by or on behalf of DTC only through the Participants or the Indirect Participants. The ownership interests in, and transfers of ownership interests in, each security held by or on behalf of DTC are recorded on the records of the Participants and Indirect Participants.

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

Investors in the Global Notes who are Participants may hold their interests therein directly through DTC. Investors in the Global Notes who are not Participants may hold their interests therein indirectly through organizations (including Euroclear and Clearstream) which are Participants. Euroclear and Clearstream will hold interests in the Global Notes on behalf of their participants through customers’ securities accounts in their respective names on the books of their respective depositories, which are Euroclear Bank S.A./N.V., as operator of Euroclear, and Citibank, N.A., as operator of Clearstream. All interests in a Global Note, including those held through Euroclear or Clearstream, may be subject to the procedures and requirements of DTC. Those interests held through Euroclear or Clearstream may also be subject to the procedures and requirements of such systems. The laws of some states require that certain Persons take physical delivery in definitive form of securities that they own. Consequently, the ability to transfer beneficial interests in a Global Note to such Persons will be limited to that extent. Because DTC can act only on behalf of the Participants, which in turn act on behalf of the Indirect Participants, the ability of a Person having beneficial interests in a Global Note to pledge such interests to Persons that do not participate in the DTC system, or otherwise take actions in respect of such interests, may be affected by the lack of a physical certificate evidencing such interests.

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

Payments in respect of the principal of, and interest and premium, if any, on a Global Note registered in the name of DTC or its nominee will be payable to DTC in its capacity as the registered holder under the indenture. Under the terms of the indenture, Issuer and the trustee will treat the Persons in whose names the notes, including the Global Notes, are registered as the owners of the notes for the purpose of receiving payments and for all other purposes.

Consequently, neither Issuer, the trustee nor any agent of Issuer or the trustee has or will have any responsibility or liability for:

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

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

Subject to compliance with the transfer restrictions applicable to the notes described herein, cross-market transfers between the Participants, on the one hand, and Euroclear or Clearstream participants, on the other hand, will be effected through DTC in accordance with DTC’s rules on behalf of Euroclear or Clearstream, as the case may be, by their respective depositaries; however, such cross-market transactions will require delivery of instructions to Euroclear or Clearstream, as the case may be, by the counterparty in such system in accordance with the rules and procedures and within the established deadlines (Brussels time) of such system. Euroclear or Clearstream, as the case may be, will, if the transaction meets its settlement requirements, deliver instructions to its respective depositary to take action to effect final settlement on its behalf by delivering or receiving interests in the relevant Global Note in

DTC, and making or receiving payment in accordance with normal procedures for same-day funds settlement applicable to DTC. Euroclear participants and Clearstream participants may not deliver instructions directly to the depositories for Euroclear or Clearstream.

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

Although DTC, Euroclear and Clearstream have agreed to the foregoing procedures to facilitate transfers of interests in the Global Notes and the Global Notes among participants in DTC, Euroclear and Clearstream, they are under no obligation to perform or to continue to perform such procedures, and may discontinue such procedures at any time. None of Issuer, the trustee and any of their respective agents will have any responsibility for the performance by DTC, Euroclear or Clearstream or their respective participants or indirect participants of their respective obligations under the rules and procedures governing their operations.

A Global Note is exchangeable for Certificated Notes if:

Certificated Notes delivered in exchange for any Global Note or beneficial interests in Global Notes will be registered in the names, and issued in any approved denominations, requested by or on behalf of the depositary (in accordance with its customary procedures).

Certificated Notes may not be exchanged for beneficial interests in any Global Note unless the transferor first delivers to the trustee a written certificate (in the form provided in the indenture) to the effect that such transfer will comply with the appropriate transfer restrictions applicable to such notes.

Issuer will make payments in respect of the notes represented by the Global Notes (including principal, premium, if any, and interest) by wire transfer of immediately available funds to the accounts specified by DTC or its nominee. Issuer will make all payments of principal, interest and premium, if any, with respect to Certificated Notes by wire transfer of immediately available funds to the accounts specified by the holders of the Certificated Notes or, if no such account is specified, by mailing a check to each such holder’s registered address. The notes represented by the Global Notes are expected to be eligible to trade in DTC’s Same-Day Funds Settlement System, and any permitted secondary market trading activity in such notes will, therefore, be required by DTC to be settled in immediately available funds. Issuer expects that secondary trading in any Certificated Notes will also be settled in immediately available funds.
