T-Mobile USA, Inc., a Delaware corporation (“T-Mobile USA” or the “Issuer”) and a direct wholly-owned subsidiary of T-Mobile US, Inc., a Delaware corporation (“T-Mobile US” or “Parent”) is offering $1,000,000,000 aggregate principal amount of its 4.950% Senior Notes due 2028 (the “2028 Notes”), $1,250,000,000 aggregate principal amount of its 5.050% Senior Notes due 2033 (the “2033 Notes”) and $750,000,000 aggregate principal amount of its 5.650% Senior Notes due 2053 (the “New 2053 Notes”). The New 2053 Notes offered hereby will be an additional issuance of the 5.650% Senior Notes due 2053 issued by the Issuer in an aggregate principal amount of $1,000,000,000 on September 15, 2022 (the “Existing 2053 Notes” and together with the New 2053 Notes, the “2053 Notes”), will be fungible with the Existing 2053 Notes and will be consolidated with and form a single series with the Existing 2053 Notes. The New 2053 Notes offered hereby will have the same terms as the Existing 2053 Notes, other than the settlement date, offering price and initial interest payment date, and will have the same CUSIP number as the Existing 2053 Notes. Immediately after giving effect to the issuance of the New 2053 Notes offered hereby, the aggregate principal amount of the New 2053 Notes offered hereby and the Existing 2053 Notes will be $1,750,000,000. In this prospectus supplement, the term “Notes” collectively refers to the 2028 Notes, the 2033 Notes, the New 2053 Notes, and, where the context requires, the Existing 2053 Notes.

We intend to use the net proceeds from this offering for general corporate purposes, which may include among other things, share repurchases and refinancing of existing indebtedness on an ongoing basis. See “Use of Proceeds.”

The 2028 Notes will bear interest at a rate of 4.950% per year and mature on March 15, 2028. The 2033 Notes will bear interest at a rate of 5.050% per year and mature on July 15, 2033. The 2053 Notes will bear interest at a rate of 5.650% per year and mature on January 15, 2053. Interest on the 2028 Notes will be paid on each March 15 and September 15, commencing March 15, 2023. Interest on the 2033 Notes and the New 2053 Notes will be paid on each January 15 and July 15, commencing July 15, 2023. See “Description of Notes—Brief Description of the Notes and the Note Guarantees—Principal, Maturity and Interest.” There is no sinking fund for the Notes.

Some or all of the Notes are permitted to be redeemed (i) at any time prior to the applicable date indicated in the table below at a price equal to 100% of the principal amount of such Notes being redeemed and a “make whole” premium and (ii) on or after the applicable date indicated in the table below at a price equal to 100% of the principal amount of such Notes being redeemed; plus, in the case of both (i) and (ii), accrued and unpaid interest, if any, to, but not including, the redemption date, as described in this prospectus supplement:

The Issuer’s obligations under the Notes will be guaranteed (such guarantees, the “Guarantees”) (i) initially by T-Mobile US and each wholly-owned subsidiary of the Issuer that is not an Excluded Subsidiary (as defined herein) and is an obligor of the Credit Agreement (as defined herein) and (ii) by any future direct or indirect subsidiary of T-Mobile US that is not a subsidiary of the Issuer or any other guarantor that owns capital stock of the Issuer. However, a guarantor will be automatically and unconditionally released from its obligations in respect of the Notes of any series if, immediately following such release and any concurrent releases of other guarantees of the subsidiary guarantors, the aggregate principal amount of indebtedness for borrowed money of non-guarantor subsidiaries that are not Excluded Subsidiaries (excluding any indebtedness under any Permitted Receivables Financing (as defined herein) and any indebtedness of an “Unrestricted Subsidiary” (or the equivalent thereof) under the Credit Agreement or Permitted Receivables Financing Subsidiary (as defined herein)) that would remain incurred or issued and outstanding would not exceed $2,000.0 million. See “Description of Notes—Brief Description of the Notes and the Note Guarantees—The Note Guarantees.”

The Notes and the Guarantees will be the Issuer’s and the guarantors’ unsubordinated unsecured obligations; will be senior in right of payment to any future indebtedness of the Issuer or any guarantor to the extent that such future indebtedness provides by its terms that it is subordinated in right of payment to the Notes and the Guarantees; will be equal in right of payment with any of the Issuer’s and the guarantors’ existing and future indebtedness and other liabilities that are not by their terms subordinated in right of payment to the Notes, including, without limitation, obligations under the Credit Agreement, the Existing T-Mobile Unsecured Notes, the Existing Sprint Unsecured Notes and the Tower Obligations (each as defined herein); will be effectively subordinated to all existing and future secured indebtedness of the Issuer or any guarantor, in each case to the extent of the value of the assets securing such indebtedness; and will be structurally subordinated to all of the liabilities and other obligations of the subsidiaries of T-Mobile US that are not obligors with respect to the Notes, including the Existing ABS Notes (as defined herein), the Existing Sprint Spectrum-Backed Notes (as defined herein), factoring arrangements and tower obligations.

This prospectus supplement includes additional information on the terms of the Notes, including redemption prices and covenants. See “Description of Notes.”

An investment in the Notes involves a high degree of risk. Prior to making a decision about investing in the Notes, you should carefully consider the following risks and uncertainties, as well as those discussed under the caption “Risk Factors” in Parent’s Annual Report on Form 10-K for the year ended December 31, 2021 filed on February 11, 2022, Parent’s Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2022 filed on May 6, 2022, Parent’s Quarterly Report on Form 10-Q for the quarterly period ended June 30, 2022 filed on July 29, 2022 and Parent’s Quarterly Report on Form 10-Q for the quarterly period ended September 30, 2022 filed on October 27, 2022. If any of the risks described in this prospectus supplement, the accompanying prospectus or any related free writing prospectus, or the risks described in any documents incorporated by reference in this prospectus supplement, the accompanying prospectus or any related free writing prospectus, actually occur, our business, prospects, financial condition or operating results could be harmed. In such case, the trading price of the Notes could decline, and you may lose all or part of your investment.

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

Assuming that on September 30, 2022, the Q4 ABS Issuance, the Amendment and Restatement, the Q4 Maturity Payment and this offering had been completed, we would have had approximately $82.0 billion of outstanding indebtedness and other obligations, excluding letter of credit obligations, including $74.2 billion of pari passu outstanding unsecured indebtedness. Our pari passu unsecured indebtedness would consist of $3.0 billion of Notes offered hereby, $53.1 billion of Existing T-Mobile Unsecured Notes, $14.2 billion of Existing Sprint Unsecured Notes and $4.0 billion in Tower Obligations. We also would have had $7.5 billion of revolving borrowings available on an unsecured basis under the Credit Agreement. In addition, as of September 30, 2022, our effectively senior, secured indebtedness would have consisted of an aggregate principal amount of $3.2 billion of Existing Sprint Spectrum-Backed Notes, with up to $3.8 billion remaining available for issuance under the Sprint Spectrum Note Facility, and $750 million of Existing ABS Notes.

Our ability to make payments on our debt, to repay our indebtedness when due and to fund our capital intensive business and operations and significant planned capital expenditures will depend on our ability to generate cash in the future. There can be no assurance that sufficient funds will be available to us under our borrowings or otherwise. Our ability to produce cash from operations is subject to a number of risks, including:

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

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

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

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

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

Any of these risks could have a material adverse effect on our business, financial condition and operating results.

Although we have substantial indebtedness, we may still be able to incur significantly more debt, including secured debt, as market conditions and contractual obligations permit, which could further reduce the cash available to us to invest in operations, as a result of increased debt service obligations. The terms of the agreements governing our long-term indebtedness allow for the incurrence of additional indebtedness by us and our subsidiaries, subject to specified limitations. In particular, upon the Amendment and Restatement, we had $7.5 billion available for borrowings under the Revolving Credit Facility (as defined under “Description of Other Indebtedness and Certain Financing Transactions—Credit Agreement”). The Notes do not limit our ability to incur unsecured indebtedness, and allow us to incur substantial secured indebtedness. The more leveraged we become, the more we, and in turn the holders of our securities, become exposed to the risks described above in the risk factor entitled “Our substantial level of indebtedness could adversely affect our business, financial condition and operating results.”

Parent’s Board of Directors has authorized a stock repurchase program for up to $14.0 billion of Parent’s common stock through September 30, 2023 (the “2022 Stock Repurchase Program”), including up to $3.0 billion through 2022, with approximately $1.5 billion spent by the Company on share repurchases as of October 20, 2022. Repurchases are expected to be made from available cash on hand and proceeds of one or more debt issuances or other borrowings, including this offering of Notes, based on our evaluation of market conditions and other factors.

The indentures governing the Notes, the Existing T-Mobile Unsecured Notes, the Existing Sprint Unsecured Notes, the Existing ABS Notes and the Existing Sprint Spectrum-Backed Notes do not limit our ability to conduct future repurchases in any way. Any repurchases would reduce the cash and stockholders’ equity that is available to repay the Notes.

The Notes and the Guarantees will be general unsecured, unsubordinated obligations ranking effectively junior in right of payment to all existing and future secured debt of Parent, the Issuer and each Subsidiary Guarantor, to the extent of the value of the assets securing such debt. The Notes will also permit us to incur certain secured debt.

If the Issuer or a guarantor is declared bankrupt, becomes insolvent or is liquidated or reorganized, any secured debt of the Issuer or that guarantor will be entitled to be paid in full from the assets of the Issuer or guarantor, as applicable, securing that debt before any payment may be made with respect to the Notes or the Guarantees of such guarantor.

Holders of the Notes will participate ratably in any remaining assets with all other holders of the Issuer’s and such guarantor’s unsecured obligations that are not by their terms subordinated to the Notes, based upon the respective amounts owed. In any of the foregoing events, there may not be sufficient assets to pay the indebtedness and other obligations owed to secured creditors and the amounts due on the Notes. As a result, holders of the Notes would likely receive less, ratably, than holders of secured obligations of the Issuer and the guarantors.

The Notes and the Guarantees will be structurally subordinated to any existing or future liabilities and other obligations of the Issuer’s or the guarantors’ non-guarantor subsidiaries, including the Existing ABS Notes, the Existing Sprint Spectrum-Backed Notes, factoring arrangements and tower obligations. Accordingly, creditors of current and future subsidiaries of the Issuer or the guarantors that are not obligors with respect to the Notes would have claims with respect to the assets of those subsidiaries that would rank structurally senior to the Notes and the Guarantees. In the event of any distribution or payment of assets of such subsidiaries in any dissolution, winding up, liquidation, reorganization or other bankruptcy proceeding, the claims of those creditors would have to be satisfied prior to making any such distribution or payment to the Issuer or the applicable guarantor in respect of direct or indirect equity interests in such subsidiaries. Certain subsidiaries of the Issuer that are prohibited from providing guarantees of the Notes (such as special purpose finance entities and a reinsurance subsidiary), as well as non-wholly owned and immaterial subsidiaries, will not provide guarantees of the Notes. As of September 30, 2022, subsidiaries that will not provide guarantees of the Notes that were included in Parent’s consolidated financial statements as of such date had approximately $11.9 billion of total assets and approximately $5.3 billion in indebtedness and Tower Obligations outstanding. See “Description of Notes—Brief Description of the Notes and the Note Guarantees—The Note Guarantees.” In addition, subsequent to September 30, 2022, a subsidiary of T-Mobile USA issued $750 million of Existing ABS Notes and approximately $1.0 billion in EIP receivables were transferred to the subsidiaries associated with the ABS facility. Subsidiaries associated with the ABS facility will not provide guarantees of the Notes.

Our ability to meet existing or future debt obligations and to reduce indebtedness will depend on future performance and the other cash requirements of our businesses. Our performance, to a certain extent, is subject to general economic conditions and financial, competitive, business, political, regulatory and other factors, including third party rating agency assessments, that are beyond our control. In addition, our ability to borrow funds in the future to make payments on debt will depend on the satisfaction of covenants in the indentures governing the Notes, the Existing T-Mobile Unsecured Notes and the Existing Sprint Unsecured Notes, the Credit Agreement, other debt agreements and other agreements we may enter into in the future. Specifically, under our Credit Agreement, we will need to maintain a Leverage Ratio (as defined in the Credit Agreement) of 4.50 to 1.00 or less at each fiscal quarter end beginning with December 31, 2022. We cannot assure you that we will continue to generate sufficient cash flow from operations or that future equity issuances or borrowings will be available to us in an amount sufficient to enable

us to satisfy the financial covenants under the Credit Agreement, service our debt or repay our indebtedness in a timely manner or on favorable or commercially reasonable terms, or at all. If we are unable to satisfy such financial covenants or to generate sufficient cash to timely repay our debt, our lenders could accelerate the maturity of some or all of our outstanding indebtedness. As a result, we may need to refinance all or a portion of our remaining existing indebtedness prior to its maturity. We also may need to refinance certain indebtedness. Disruptions in the financial markets, unfavorable rating agency assessments, the general amount of debt being refinanced at the same time, and our financial position and performance could make it more difficult to obtain debt or equity financing on favorable or commercially reasonable terms or at all. In addition, instability in the global financial markets has from time to time resulted in volatility in the capital markets. This volatility could limit our access to the credit markets, leading to higher borrowing costs or, in some cases, the inability to obtain financing on terms that are acceptable to us, or at all. Any such failure to obtain additional financing could jeopardize our ability to repay, refinance or reduce debt obligations. If we were able to obtain funds, it may not be on terms and conditions acceptable to us, which could limit or preclude our ability to pursue new opportunities, expand our service, upgrade our networks, engage in acquisitions or purchase additional spectrum, thus limiting our ability to expand our business, which could have a material adverse effect on our business, financial condition and operating results.

Further, should we need to raise additional capital, the foreign ownership restrictions mandated by the FCC, and applicable to us, could limit our ability to attract additional equity financing outside the United States.

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

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

The failure to purchase the Existing T-Mobile 2013 Indenture Notes, the Existing T-Mobile 2020 Indenture Notes, the Existing Sprint Spectrum-Backed Notes or the applicable Existing Sprint Unsecured Notes, as required under the respective indentures, would result in defaults under such indentures in addition to any events of default

under the Credit Agreement resulting from a change of control triggering event thereunder, any of which could have material adverse consequences for us and the holders of the Notes. Any such event of default would likely trigger an event of default on other outstanding or future indebtedness.

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

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

In addition, the Credit Agreement also contains a financial maintenance covenant, requiring the Issuer to maintain a Leverage Ratio of 4.50 to 1.00 or less at each fiscal quarter end beginning with December 31, 2022.

These restrictions could limit our ability to obtain debt financing, refinance or pay principal on our outstanding indebtedness, complete acquisitions for cash or indebtedness or react to business, economic, market and industry conditions and other changes in our operating environment or the economy. Any future indebtedness that we incur may contain similar or more restrictive covenants.

Any failure to comply with the restrictions of the indentures governing the Notes, the Existing T-Mobile Unsecured Notes or the Existing Sprint Unsecured Notes, the Credit Agreement or other financing agreements may result in an event of default under these agreements, which in turn may result in defaults or acceleration of obligations under these and other agreements, giving our lenders and other debt holders the right to terminate any commitments they had made to provide us with further funds or the right to require us to repay all amounts then outstanding plus any interest, fees, penalties or premiums. An event of default may also compel us to sell certain assets securing indebtedness under certain of these agreements. Any of these events would have a material adverse effect on our business, financial condition and operating results.

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

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

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

The measure of insolvency for purposes of the foregoing considerations will vary depending upon the law of the jurisdiction that is being applied in any such proceeding, such that we cannot be certain as to the standards a court would use to determine whether or not the Issuer or the guarantors were insolvent at the relevant time or, regardless of the insolvency standard applied by the court, that such court would not determine (i) that the Issuer or a guarantor were indeed insolvent on that date, (ii) that any payments to the holders of the Notes (including under the Guarantees) did not constitute preferences, fraudulent transfers or conveyances on other grounds or (iii) whether the Notes or any Guarantees would be subordinated to the Issuer’s or any of the guarantors’ other debt. Generally, however, an entity would be considered insolvent if, at the time it incurred the debt or issued the Guarantee:

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

If a Guarantee is avoided as a fraudulent conveyance, fraudulent transfer, or preference, or found to be unenforceable for any other reason, you will not have a claim against that obligor and will only be our creditor or that of any guarantor whose obligation was not set aside or found to be unenforceable. In addition, such a loss of a Guarantee generally will constitute an event of default under the indentures governing the Notes and the Existing T-Mobile Unsecured Notes and the Credit Agreement, which events of default would allow the relevant noteholders or lenders to accelerate the amounts due and payable thereunder, and we may not be able to pay any such amounts.

The indentures governing the Notes will contain a provision intended to limit each guarantor’s liability to the maximum amount that it could incur without causing the incurrence of obligations under its Guarantee to be a fraudulent transfer. This provision may not be effective (as a legal matter or otherwise) to protect the Guarantees from being avoided under fraudulent transfer law, or may eliminate the guarantor’s obligations or reduce the guarantor’s obligations to an amount that effectively makes the Guarantee worthless. In a Florida bankruptcy court decision (which was subsequently reversed by a district court on other grounds and then reinstated by the applicable circuit court of appeals), this kind of provision was found to be ineffective to protect the Guarantees.

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

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

For so long as any obligations under the Credit Agreement remain outstanding, any guarantee of the Notes may be released without action by, or consent of, any holder of the Notes, if the related guarantor is no longer a guarantor of obligations under the Credit Agreement or certain other indebtedness of the Issuer or any other guarantor (except, in each case, by or as a result of payment under such guarantee or direct obligation). See “Description of Notes—Brief Description of the Notes and the Note Guarantees—The Note Guarantees.” The lenders under the Credit Agreement will have the discretion to release the guarantees under the Credit Agreement in a variety of circumstances. You will not have a claim as a creditor against any entity that is no longer a guarantor of the Notes, and the indebtedness and other liabilities, including trade payables, whether secured or unsecured, of former guarantor subsidiaries will be structurally senior to claims of holders of the Notes.

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

Assuming that on September 30, 2022, the Q4 ABS Issuance, the Amendment and Restatement, the Q4 Maturity Payment and this offering had been completed, we would have had outstanding approximately $74.2 billion in aggregate principal amount of debt securities, maturing in 2023 through 2062, $3.9 billion of which would have been senior secured debt securities and $70.3 billion of which would have been senior unsecured debt securities. Deutsche Telekom, which, as of October 20, 2022, controlled approximately 52.2% of the common stock of Parent, would have held approximately $1.5 billion of these debt securities, maturing in 2028. We have on file an effective shelf registration statement with respect to these debt securities held by Deutsche Telekom and Deutsche Telekom could sell all or any portion of them at any time.

The 2028 Notes and the 2033 Notes each will be a new class of security for which there is no established trading market. An active trading market may not develop for such Notes. In addition, there may cease to be a market for the 2053 Notes. Subsequent to their initial issuance, the Notes may trade at a discount from their initial offering price, depending upon prevailing interest rates, the market for similar notes, our operating performance and financial condition and other factors. The Issuer does not intend to apply for the Notes to be listed on any securities exchange or to arrange for the Notes to be quoted on any quotation system. If an active public trading market for the Notes does not develop or ceases to exist, the market price and liquidity of the Notes may be adversely affected.

Credit rating agencies continually revise their ratings for companies they follow, including us. Changes in our performance, leverage or industry, or changes in the credit ratings agencies’ ratings methodologies, could lead to ratings downgrades. Any ratings downgrade could adversely affect the trading price of the Notes, or the trading market for the Notes, to the extent a trading market for the Notes exists or develops. The condition of the financial and credit markets and prevailing interest rates have fluctuated in the past and are likely to fluctuate in the future, and any fluctuation may impact the trading price of the Notes.

We estimate that the net proceeds from the sale of the Notes in this offering will be approximately $3.010 billion, excluding accrued interest on the New 2053 Notes and after deducting underwriting discounts and commissions and estimated offering expenses payable by us.

We intend to use the net proceeds from this offering for general corporate purposes, which may include among other things, share repurchases and refinancing of existing indebtedness on an ongoing basis.

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

The table below sets forth our cash and cash equivalents and capitalization as of September 30, 2022:

You should read this table in conjunction with “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and related notes thereto included in Parent’s Quarterly Report on Form 10-Q filed on October 27, 2022, which is incorporated by reference in this prospectus supplement.

T-Mobile USA’s senior unsecured notes set forth in the tables below are currently outstanding. The indentures governing these senior unsecured notes contain covenants and other terms, including covenants that, among other things, restrict the ability of T-Mobile USA and certain of its subsidiaries to create liens or other encumbrances and merge, consolidate or sell, or otherwise dispose of, substantially all of their assets, as well as customary events of default. These covenants and events of default are subject to a number of important qualifications and exceptions.

T-Mobile USA’s senior notes set forth in the table below (collectively, the “Existing T-Mobile 2022 Indenture Notes”) were issued pursuant to an indenture, dated as of September 15, 2022, among T-Mobile USA, Parent and Deutsche Bank Trust Company Americas, as trustee. The Existing T-Mobile 2022 Indenture Notes are T-Mobile USA’s unsecured obligations and are guaranteed by Parent and each wholly-owned subsidiary of T-Mobile USA (other than certain excluded subsidiaries) that is or becomes an obligor of the Credit Agreement or issues or guarantees certain capital markets debt securities, and any future direct or indirect subsidiary of Parent that is not a subsidiary of T-Mobile USA or any other guarantor that owns capital stock of T-Mobile USA. The guarantees are provided on a senior unsecured basis. The Notes offered hereby will be issued under the same base indenture as the Existing T-Mobile 2022 Indenture Notes.

T-Mobile USA’s senior notes set forth in the table below (collectively, the “Existing T-Mobile 2020 Indenture Notes”) were issued pursuant to an indenture, dated as of April 9, 2020, among T-Mobile USA, Parent and Deutsche Bank Trust Company Americas, as trustee. The Existing T-Mobile 2020 Indenture Notes are T-Mobile USA’s unsecured obligations and are guaranteed by Parent and each wholly-owned subsidiary of T-Mobile USA (other than certain excluded subsidiaries) that is or becomes an obligor of the Credit Agreement or issues or guarantees certain capital markets debt securities, and any future direct or indirect subsidiary of Parent that is not a subsidiary of T-Mobile USA or any other guarantor that owns capital stock of T-Mobile USA. The guarantees are provided on a senior unsecured basis. The Existing T-Mobile 2020 Indenture Notes are subject to optional redemption and will require T-Mobile USA to offer to repurchase the Existing T-Mobile 2020 Indenture Notes if Parent or T-Mobile USA experiences certain change of control triggering events.

The Notes offered hereby will be issued under a different base indenture than the Existing T-Mobile 2020 Indenture Notes, will be different series than the Existing T-Mobile 2020 Indenture Notes, will not vote together with any of the Existing T-Mobile 2020 Indenture Notes, will not be required to be redeemed on a pro rata basis with any of the Existing T-Mobile 2020 Indenture Notes and will not trade with any of the Existing T-Mobile 2020 Indenture Notes.

T-Mobile USA’s senior unsecured notes set forth in the table below (the “Existing T-Mobile 2013 Indenture Notes” and, together with the Existing T-Mobile 2020 Indenture Notes and the Existing T-Mobile 2022 Indenture Notes, the “Existing T-Mobile Unsecured Notes”) were issued pursuant to an indenture (the “April 2013 Indenture”), dated as of April 28, 2013, among T-Mobile USA, the other guarantors party thereto, and Deutsche Bank Trust Company Americas, as trustee. The Existing T-Mobile 2013 Indenture Notes are T-Mobile USA’s unsecured obligations, are guaranteed on a senior unsecured basis by Parent and by all of T-Mobile USA’s wholly-owned domestic restricted subsidiaries (other than, in each case, certain designated special purpose entities, a reinsurance subsidiary and immaterial subsidiaries) and are required to be guaranteed by all of T-Mobile USA’s restricted subsidiaries that guarantee certain of T-Mobile USA’s indebtedness and any future subsidiary of Parent that directly or indirectly owns any of T-Mobile USA’s equity interests. T-Mobile USA may, at its option, redeem some or all of the Existing T-Mobile 2013 Indenture Notes at any time on or after the dates set forth below under “Earliest Optional Redemption” at the redemption price set forth in the governing indenture, or prior to such dates at a specified “make-whole” redemption price plus accrued and unpaid interest to, but not including, the redemption date. In addition, prior to the dates set forth below under “Optional Redemption with Equity Proceeds,” T-Mobile USA may also redeem up to the percentage of the aggregate principal amount set forth in such column, at the redemption prices set forth in the governing indenture, with the net cash proceeds of certain sales of equity securities, including the sale of Parent’s common stock.

The Notes offered hereby will be issued under a different base indenture than the Existing T-Mobile 2013 Indenture Notes, will be different series than the Existing T-Mobile 2013 Indenture Notes, will not vote together with any of the Existing T-Mobile 2013 Indenture Notes, will not be required to be redeemed on a pro rata basis with any of the Existing T-Mobile 2013 Indenture Notes and will not trade with any of the Existing T-Mobile 2013 Indenture Notes.

The Sprint Capital Corporation and Sprint notes set forth in the table below (collectively, the “Existing Sprint Unsecured Notes”) are currently outstanding. The Existing Sprint Unsecured Notes are the applicable issuer’s unsecured obligations and are guaranteed on a senior unsecured basis (i) by Parent, T-Mobile USA and Sprint Communications, in the case of notes issued by Sprint and (ii) by Parent, T-Mobile USA, Sprint and Sprint Communications in the case of notes issued by Sprint Capital Corporation. The issuer may, at its option, redeem some or all of the Existing Sprint Unsecured Notes at any time at a specified “make-whole” redemption price plus accrued and unpaid interest to, but not including, the redemption date.

The 6.875% senior notes due 2028 and the 8.750% senior notes due 2032 were issued pursuant to an indenture, dated as of October 1, 1998 (the “1998 Sprint Indenture”), among Sprint Capital Corporation, Sprint and Bank of New York Mellon Trust Company, N.A., as successor to Bank One, N.A., as trustee. The 7.875% senior notes due

2023, the 7.125% senior notes due 2024, the 7.625% senior notes due 2025 and the 7.625% senior notes due 2026 were issued pursuant to an indenture, dated as of September 11, 2013 (the “2013 Sprint Indenture” and collectively with the 1998 Sprint Indenture, the “Existing Sprint Indentures”), among Sprint and The Bank of New York Mellon Trust Company, N.A., as trustee.

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

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

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

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

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

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

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

Each Existing Sprint Spectrum Note Entity is a separate legal entity with its own separate creditors that would be entitled, prior to and upon the liquidation of the Existing Sprint Spectrum Note Entity, to be satisfied out of the

Existing Sprint Spectrum Note Entity’s assets prior to any assets of the Existing Sprint Spectrum Note Entity becoming available to its parent entities (including T-Mobile). Accordingly, the assets of the Existing Sprint Spectrum Note Entities would not be available to satisfy the debts and other obligations owed to other creditors of T-Mobile until the obligations of the Existing Sprint Spectrum Note Entities (including under the Existing Sprint Spectrum-Backed Notes) are paid in full.

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

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

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

Borrowings under the Credit Agreement will bear interest based upon the applicable benchmark rate, depending on the type of loan and, in some cases, T-Mobile USA’s election, plus a margin. The benchmark rates consist of (i) the Base Rate, (ii) Adjusted Term SOFR, (iii) the EURIBO Rate, (iv) Daily Simple SONIA, (v) the CDO Rate or (vi) Daily Simple SARON, each as described in the Credit Agreement. Applicable margins range from (x) 0.00% to 0.125% in the case of Base Rate Loans (as defined in the Credit Agreement) and (y) 0.875% to 1.125% in the case of Term Benchmark Loans and RFR Loans (each as defined in the Credit Agreement), in each case depending on the credit rating of T-Mobile USA’s senior unsecured long-term debt (the “Applicable Debt Rating”).

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

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

Subject to customary exceptions, the Credit Agreement contains certain limitations on the ability of T-Mobile USA and its restricted subsidiaries to engage in certain activities, including incurrence of liens and consolidations and mergers. The Credit Agreement also contains a financial maintenance covenant, requiring T-Mobile USA to maintain a Leverage Ratio of 4.50 to 1.00 or less at each fiscal quarter end beginning with December 31, 2022.

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

The Credit Agreement contains customary events of default, including, without limitation, payment defaults, covenant defaults, breaches of certain representations and warranties, cross defaults to certain indebtedness, certain events of bankruptcy and insolvency, certain judgments, a change of control coupled with a ratings downgrade, certain ERISA events and the invalidity of the loan documents. If an event of default occurs and is not cured within

any applicable grace period or is not waived, the administrative agent and the lenders will be entitled to take various actions, including, without limitation, the acceleration of amounts due thereunder.

On October 12, 2022, a subsidiary of T-Mobile USA issued $750 million of 4.910% Class A senior asset-backed notes (the “Existing ABS Notes”) to third-party investors in a private placement transaction. The Existing ABS Notes are secured by approximately $1.0 billion of gross EIP receivables and future collections on such receivables. The Existing ABS Notes issued and the assets securing this debt will be included on T-Mobile’s Consolidated Balance Sheets.

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

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

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

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

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

As of the Merger closing date (April 1, 2020), T-Mobile recognized Property and equipment with a fair value of $2.8 billion and tower obligations related to amounts owed to CCI under the leaseback of $1.1 billion. Additionally, T-Mobile recognized $1.7 billion in other long-term liabilities associated with contract terms that are unfavorable to current market rates, which include unfavorable terms associated with the fixed-price purchase option in 2037.

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

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

T-Mobile has factoring arrangements, as amended from time to time, to sell certain EIP accounts receivable and service accounts receivable on a revolving basis as a source of additional liquidity. In 2015, T-Mobile entered into the EIP sale arrangement, which is a revolving facility and currently has a maximum funding commitment of $1.3 billion and on November 2, 2022, T-Mobile extended the scheduled expiration date to November 18, 2023. As of September 30, 2022, the EIP sale arrangement provided funding of $1.3 billion. In 2014, T-Mobile entered into the service accounts receivable arrangement which is also a revolving facility and currently has a maximum funding commitment of $950 million and on February 28, 2022, extended the scheduled expiration date to February 28, 2023. As of September 30, 2022, the service accounts receivable arrangement provided funding of $775 million. As of September 30, 2022, T-Mobile derecognized net receivables of $2.4 billion upon sale through these arrangements. These arrangements are not reflected on Parent’s consolidated balance sheet.

T-Mobile USA, Inc., a Delaware corporation (the “Issuer”), is issuing: $1,000,000,000 in aggregate principal amount of 4.950% Senior Notes due 2028 (the “2028 Notes”), $1,250,000,000 in aggregate principal amount of 5.050% Senior Notes due 2033 (the “2033 Notes”) and $750,000,000 in aggregate principal amount of 5.650% Senior Notes due 2053 (the “New 2053 Notes,” and together with the 2028 Notes and the 2033 Notes, the “Notes”). The New 2053 Notes offered hereby will be an additional issuance of the 5.650% Senior Notes due 2053 issued by the Issuer in an aggregate principal amount of $1,000,000,000 on September 15, 2022 (the “Existing 2053 Notes” and together with the New 2053 Notes, the “2053 Notes”). The New 2053 Notes offered hereby will be fungible with the Existing 2053 Notes and will be consolidated with and form a single series with the Existing 2053 Notes. The New 2053 Notes offered hereby will have the same terms as the Existing 2053 Notes, other than the settlement date, offering price and initial interest payment date, and will have the same CUSIP number as the Existing 2053 Notes. Immediately after giving effect to the issuance of the New 2053 Notes offered hereby, the aggregate principal amount of the New 2053 Notes offered hereby and the Existing 2053 Notes will be $1,750,000,000.

The Notes will be issued under a base indenture (the “Base Indenture”), dated as of September 15, 2022, among the Issuer, Parent and Deutsche Bank Trust Company Americas, as trustee (together with its successors and assigns, the “Trustee”), as supplemented (i) with respect to the 2028 Notes by a supplemental indenture dated as of the settlement date of the 2028 Notes (the “2028 Notes Supplemental Indenture”), (ii) with respect to the 2033 Notes by a supplemental indenture dated as of the settlement date of the 2033 Notes (the “2033 Notes Supplemental Indenture”) and (iii) with respect to the New 2053 Notes by the Second Supplemental Indenture, dated as of September 15, 2022, and an additional supplemental indenture dated as of the settlement date of the New 2053 Notes (collectively, the “2053 Notes Supplemental Indenture” and each of the 2028 Notes Supplemental Indenture, the 2033 Notes Supplemental Indenture and the 2053 Notes Supplemental Indenture, with respect to the applicable series, the “Supplemental Indenture”) among the Issuer, Parent, the Subsidiary Guarantors, the Trustee, Deutsche Bank Trust Company Americas, as paying agent and Deutsche Bank Trust Company Americas, as registrar and transfer agent. In this Description of Notes, the term “Indenture” refers to the Base Indenture as supplemented separately by the Supplemental Indenture for the applicable series of Notes. The terms of the Notes of each series include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”).

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

The obligations and covenants of the Issuer described in this Description of Notes are only of the Issuer, and not of Parent. Although Parent is a guarantor of the Notes, Parent and any of its Subsidiaries that are not the Issuer or the Issuer’s Subsidiaries are generally not subject to any of the obligations and covenants described hereunder.

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

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

The Notes of each series:

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

Assuming that on September 30, 2022, the Q4 ABS Issuance, the Amendment and Restatement and the Q4 Maturity Payment (each as defined in “Summary—Recent Developments”) and this offering had been completed, we would have had approximately $82.0 billion of outstanding indebtedness and other obligations, excluding letter of credit obligations, including $74.2 billion of pari passu outstanding unsecured indebtedness. Our pari passu unsecured indebtedness would consist of $3.0 billion of Notes offered hereby, $53.1 billion of Existing T-Mobile Unsecured Notes, $14.2 billion of Existing Sprint Unsecured Notes and $4.0 billion in Tower Obligations. We also would have had $7.5 billion of revolving borrowings available on an unsecured basis under the Credit Agreement. Our effectively senior, secured indebtedness would consist of an aggregate principal amount of $3.2 billion of Existing Sprint Spectrum-Backed Notes outstanding, with up to $3.8 billion remaining available for issuance under the Sprint Spectrum Note Facility (as defined under “Description of Other Indebtedness and Certain Financing Transactions—Existing Sprint Spectrum Note Facility”), and an aggregate principal amount of $750 million of Existing ABS Notes.

As of September 30, 2022, subsidiaries that will not provide guarantees of the Notes that were included in Parent’s consolidated financial statements as of such date had approximately $11.9 billion of total assets and approximately $5.3 billion of indebtedness and Tower Obligations outstanding. In addition, subsequent to September 30, 2022, a subsidiary of T-Mobile USA issued $750 million of Existing ABS Notes and approximately $1.0 billion in EIP receivables were transferred to the subsidiaries associated with the ABS facility. Subsidiaries associated with the ABS facility will not provide guarantees of the Notes.

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

Each Note Guarantee of the Notes by a Guarantor:

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

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

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

The Issuer will issue $3,000,000,000 in aggregate principal amount of Notes in this offering, of which $1,000,000,000 in aggregate principal amount will be 2028 Notes, $1,250,000,000 in aggregate principal amount will be 2033 Notes and $750,000,000 in aggregate principal amount will be New 2053 Notes.

The Issuer may issue further additional Notes of any series from time to time, and such additional Notes of such series may be issued under the Base Indenture as supplemented either by the Supplemental Indenture for such series of Notes or one or more other supplemental indentures. The New 2053 Notes will constitute Additional Notes under the Indenture. Any issuance of additional Notes is subject to all of the covenants in the Indenture. The Notes of any series and any additional Notes of such series subsequently issued will be treated as a single series for all purposes under the Indenture, including, without limitation, waivers, amendments, redemptions and offers to purchase; provided that any additional Notes that are not fungible with the Notes of any series (or with any other additional Notes of that series) for U.S. federal income tax purposes will have a separate CUSIP, ISIN, common code or other identifying number, as applicable.

The Issuer will issue Notes in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof. The 2028 Notes will mature on March 15, 2028, the 2033 Notes will mature on July 15, 2033 and the 2053 Notes will mature on January 15, 2053.

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

Interest on the 2028 Notes will accrue at the rate of 4.950% per annum. Interest on the 2028 Notes will be payable semiannually in arrears on March 15 and September 15, commencing on March 15, 2023. The Issuer will make each interest payment to the holders of record of the 2028 Notes on the immediately preceding March 1 or September 1 (whether or not a Business Day).

Interest on the 2033 Notes will accrue at the rate of 5.050% per annum and interest on the 2053 Notes will accrue at the rate of 5.650% per annum. Interest on the 2033 Notes and the New 2053 Notes will be payable semiannually in arrears on January 15 and July 15, commencing on July 15, 2023. The Issuer will make each interest payment to the holders of record of the 2033 Notes and the New 2053 Notes on the immediately preceding January 1 or July 1 (whether or not a Business Day).

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

Each series of Notes initially will be evidenced by one or more global notes deposited with a custodian for, and registered in the name of, Cede & Co., as nominee of The Depository Trust Company (“DTC”).

The Issuer does not intend to apply for the Notes to be listed on any securities exchange or to arrange for the Notes to be quoted on any quotation system.

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

The Trustee will initially act as paying agent, registrar and transfer agent where Notes may be presented for payment. The Issuer may change the paying agent, registrar or transfer agent without prior notice to the holders of the Notes, and the Issuer or any of its Subsidiaries may act as paying agent or registrar.

Except as set forth below, the global notes may be transferred, in whole and not in part, only to another nominee of DTC or to a successor of DTC or its nominee.

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

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

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

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

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

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

“Par Call Date” means (i) with respect to the 2028 Notes, February 15, 2028 (one month prior to the maturity date of such 2028 Notes), (ii) with respect to the 2033 Notes, April 15, 2033 (three months prior to the maturity date of such 2033 Notes) and (iii) with respect to the 2053 Notes, July 15, 2052 (six months prior to the maturity date of such 2053 Notes).

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

The Treasury Rate shall be determined by the Issuer after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third business day preceding the redemption date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily)—H.15” (or any successor designation or publication) (“H.15”) under the caption “U.S. government securities–Treasury constant maturities–Nominal” (or any successor caption or heading). In determining the Treasury Rate, the Issuer shall select, as applicable: (1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the redemption date to the applicable Par Call Date (the “Remaining Life”); or (2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields – one yield corresponding to the Treasury constant maturity on H.15

immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life – and shall interpolate to the applicable Par Call Date, on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the redemption date.

If on the third business day preceding the redemption date H.15 or any successor designation or publication is no longer published, the Issuer shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second business day preceding such redemption date of the United States Treasury security maturing on, or with a maturity that is closest to, the applicable Par Call Date, as applicable. If there is no United States Treasury security maturing on the applicable Par Call Date, but there are two or more United States Treasury securities with a maturity date equally distant from such Par Call Date, one with a maturity date preceding such Par Call Date, and one with a maturity date following such Par Call Date, the Issuer shall select the United States Treasury security with a maturity date preceding such Par Call Date. If there are two or more United States Treasury securities maturing on the applicable Par Call Date, or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Issuer shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.

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

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

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

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

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

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

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

No Notes of $2,000 or less can be redeemed in part. Notices of redemption will be sent electronically or mailed by first class mail at least 10 days but not more than 60 days before the redemption date to each holder of Notes to be redeemed at its registered address, except that redemption notices may be sent more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the Notes of a series or a satisfaction and discharge of the Indenture with respect to such series. Any such notice of redemption may, at the Issuer’s discretion, state that such redemption is subject to one or more conditions precedent, including, but not limited to, completion of an equity offering, other offering, issuance of Indebtedness or other corporate transaction or event. In addition, if such redemption or notice is subject to satisfaction of one or more conditions precedent, such notice shall state that, in the Issuer’s discretion, the redemption date may be delayed until such time as any or all such conditions shall be satisfied (or waived by the Issuer in its sole discretion), or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied (or waived by the Issuer in its sole discretion) by the redemption date (whether the original redemption date or the redemption date so delayed). In addition, the Issuer may provide in such notice that payment of the redemption and performance of the Issuer’s obligations with respect to such redemption may be performed by another Person.

If any Note is to be redeemed in part only, the notice of redemption that relates to that Note will state the portion of the principal amount of that Note that is to be redeemed. If in definitive form, a new Note in principal amount equal to the unredeemed portion of the original Note will be issued in the name of the holder of Notes upon cancellation of the original note. Except to the extent that a notice of redemption is conditional, Notes called for redemption become due on the date fixed for redemption. On and after the redemption date, interest ceases to accrue on Notes or portions of Notes called for redemption.

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

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

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

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

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

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

All such reports will be prepared in all material respects in accordance with all of the rules and regulations applicable to such reports; provided that, if Parent is not required under the rules and regulations of the SEC to file such reports with the SEC for public availability, such reports need not be prepared in accordance with all of the rules and regulations applicable to such reports and shall only be required to include the information or disclosure that would be required by such form to the extent that, and in the same general style of presentation as, the same or substantially similar information or disclosure is also included or incorporated by reference in this prospectus supplement pursuant to which the Notes were offered and sold. The Issuer will comply with §314(a) of the Trust Indenture Act.

If the SEC will not accept Parent’s filings for any reason, the Issuer will post the reports referred to in the preceding paragraphs on its website, on intralinks.com or another website within the time periods that would apply if Parent were required to file those reports with the SEC (including all applicable extension periods).

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

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

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

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

In the case of an Event of Default arising from certain events of bankruptcy or insolvency, with respect to the Issuer, any of its Significant Subsidiaries or any group of Subsidiaries of the Issuer that, taken together, would constitute a Significant Subsidiary of the Issuer, all outstanding Notes of such series will become due and payable immediately without further action or notice. However, the effect of such provisions may be limited by applicable laws. If any other Event of Default occurs and is continuing with respect to any series of Notes, the Trustee or the holders, with a copy to the Trustee, of at least 30% in aggregate principal amount of the then outstanding Notes of such series may declare all the Notes of such series to be due and payable immediately; provided that no such declaration may be made with respect to or as a result of any action taken, and reported publicly or to holders of Notes, more than two years prior to such declaration.

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

Subject to the provisions of the Indenture relating to the duties of the Trustee, the Trustee will be under no obligation to exercise any of the rights or powers under the Indenture or the Notes Documents at the request or direction of any holders of Notes unless such holders have offered to the Trustee indemnity or security satisfactory to it against any loss, liability or expense. Except to enforce the right to receive payment of principal, premium (if any) or interest when due, a holder may pursue a remedy with respect to the Indenture or the Notes of any series only if:

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

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

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

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

In addition, the Issuer may, at its option and at any time with respect to any series of Notes, elect to have the obligations of the Issuer and the Guarantors released with respect to the provisions of the Indenture described above under the caption “—Certain Covenants” (other than the covenant described under the caption “—Certain Covenants—Merger, Consolidation or Sale of Assets”) (such release and termination being referred to as “Covenant Defeasance”), and thereafter any omission to comply with such obligations or provisions will not constitute a Default or Event of Default with respect to such Notes. In the event Covenant Defeasance occurs with respect to any series of Notes in accordance with the Indenture, the Events of Default described under clauses (3) through (9) (in the case of clauses (7) and (8), only with respect to the Issuer’s Subsidiaries) under the caption “—Events of Default and Remedies,” in each case, will no longer constitute an Event of Default.

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

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

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

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

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

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

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

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

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

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

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

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

Subject to such provisions, the Trustee will be under no obligation to exercise any of its rights or powers under the Indenture at the request of any holder of Notes of the applicable series, unless such holder has offered to the Trustee security and indemnity satisfactory to it against the losses, liabilities and expenses that might be incurred by it in compliance with such request or direction.

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

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

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

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

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

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

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

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

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

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

A Global Note is exchangeable for Certificated Notes if:

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

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

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

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

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

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

This discussion is limited to beneficial owners who hold the Notes as “capital assets” within the meaning of Section 1221 of the Code (generally, property held for investment). In addition, this discussion is limited to persons purchasing the Notes for cash at the price of the applicable series of the Notes shown on the front cover of this prospectus (plus, in the case of the New 2053 Notes, accrued interest from January 15, 2023 (the “offering price”)). This discussion does not address all U.S. federal income tax consequences relevant to a beneficial owner’s particular circumstances, including the impact of the Medicare contribution tax on net investment income. In addition, it does not address consequences relevant to beneficial owners subject to special rules, including, without limitation:

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

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

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

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

We intend, for United States federal income tax purposes, to treat the New 2053 Notes as issued pursuant to a “qualified reopening” of the Existing 2053 Notes, which had an issue price of 99.735%. Accordingly, we intend to treat the New 2053 Notes as having the same issue price and issue date as the Existing 2053 Notes. The remainder of this discussion assumes the correctness of the treatment described in this paragraph.

A portion of the offering price of the New 2053 Notes will be attributable to the amount of unpaid interest on the Existing 2053 Notes that has accrued since January 15, 2023 (the “pre-issuance accrued interest”). Pursuant to certain Treasury regulations, we intend to treat a portion of the first payment of interest on the New 2053 Notes equal to such pre-issuance accrued interest as a non-taxable return of the pre-issuance accrued interest, rather than as a payment of interest on such Notes. The remainder of this discussion assumes that this treatment is correct. You should consult your tax advisor concerning the tax treatment of any pre-issuance accrued interest on the New 2053 Notes.

Interest on a Note (which, in the case of a New 2053 Note, should exclude any pre-issuance accrued interest, as discussed above) generally will be included in a U.S. Holder’s gross income and taxed as ordinary income at the time such interest is received or accrued, in accordance with such U.S. Holder’s regular method of tax accounting for U.S. federal income tax purposes.

If you purchase a New 2053 Note for an amount (excluding any amount attributable to any pre-issuance accrued interest described above) in excess of the stated principal amount of such Note, you will be considered to have purchased such Note with “bond premium” equal to the excess of your purchase price over the stated principal amount. It may be possible for you to elect to amortize the premium over the remaining term of the New 2053 Note using a constant yield method. However, because we may call the New 2053 Notes under certain circumstances at a price in excess of their stated principal amount, such amortization may be reduced, deferred and/or eliminated. Any amortized amount of the bond premium for a taxable year generally will be treated first as a reduction of interest on the New 2053 Note includible in your gross income in such taxable year to the extent thereof, then as a deduction allowed in that taxable year to the extent of your prior interest inclusions on such Note, and finally as a carryforward

allowable against your future interest inclusions on such Note. If you make such an election, your tax basis in such Note will be reduced by the amount of the allowable amortization. If you do not elect to amortize bond premium, the premium will remain a part of your tax basis in such Note. An election to amortize bond premium will apply to all taxable debt obligations held or subsequently acquired by you on or after the first day of the first taxable year to which the election applies. Once made, you may not revoke the election without the consent of the Internal Revenue Service. You should consult your tax advisor before making this election and regarding the calculation and amortization of any bond premium.

A U.S. Holder will recognize gain or loss, if any, on the sale, exchange, redemption, retirement or other taxable disposition of a Note. The amount of such gain or loss will generally equal the difference between the amount received for the Note in cash or other property valued at fair market value (less amounts attributable to any accrued but unpaid interest, which will be taxable as interest to the extent not previously included in income in the manner described above under “—Payments of Interest” and, in the case of the New 2053 Notes, any pre-issuance accrued interest, as discussed above) and the U.S. Holder’s adjusted tax basis in the Note. A U.S. Holder’s adjusted tax basis in a Note generally will be equal to the amount the U.S. Holder paid for the Note (which, in the case of a New 2053 Note, should (i) exclude the amount of any pre-issuance accrued interest and (ii) be reduced by the amount of any bond premium previously amortized by the U.S. Holder with respect to such Note). Any gain or loss will be capital gain or loss, and will be long-term capital gain or loss if the U.S. Holder has held the Note for more than one year at the time of sale or other taxable disposition. Otherwise, such gain or loss will be short-term capital gain or loss. Long-term capital gains recognized by certain non-corporate U.S. Holders, including individuals, generally will be taxable at a reduced rate. The deductibility of capital losses is subject to limitations.

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

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

For purposes of this discussion, interest does not include any pre-issuance accrued interest, as discussed above under “—Tax Consequences Applicable to U.S. Holders—Pre-Issuance Accrued Interest” however, the applicable withholding agent is likely to treat any payment of pre-issuance accrued interest in the same manner as interest.

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

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

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

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

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

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

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

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

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

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

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

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

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

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