SCHEDULE 13D/A

Explanatory Note

This Amendment No. 15 (this “Amendment No. 15”) to the Schedule 13D filed with the U.S. Securities and Exchange Commission (the “Commission”) on May 10, 2013, (as amended and supplemented from time to time, this “Schedule 13D”), is being filed by Deutsche Telekom AG, a stock corporation (Aktiengesellschaft) organized under the laws of the Federal Republic of Germany (“Deutsche Telekom”), T-Mobile Global Zwischenholding GmbH, a limited liability company (Gesellschaft mit beschränkter Haftung) organized under the laws of the Federal Republic of Germany and a direct wholly owned subsidiary of Deutsche Telekom (“T-Mobile Global”), T-Mobile Global Holding GmbH, a limited liability company (Gesellschaft mit beschränkter Haftung) organized under the laws of the Federal Republic of Germany and a direct wholly owned subsidiary of T-Mobile Global (“T-Mobile Holding”), and Deutsche Telekom Holding B.V., a limited liability company (besloten vennootschap met beperkte aansprakelijkheid) organized under the laws of the Netherlands and a direct wholly owned subsidiary of T-Mobile Holding (“DT Holding” and, together with Deutsche Telekom, T-Mobile Global and T-Mobile Holding, the “Reporting Persons”, and each, a “Reporting Person”), pursuant to Section 13(d) of the Exchange Act, and Rule 13d-2(a) thereunder, with respect to the shares of common stock, par value $0.00001 per share (the “Common Stock”), of T-Mobile US, Inc., a Delaware corporation (the “Issuer” or “T-Mobile”).

The Reporting Persons are party to certain agreements with the Separately Filing Group Members and the Claure Parties, which agreements contain, among other things, certain voting agreements and transfer and other restrictions. As a result, the Reporting Persons may be deemed to be members of a “group” within the meaning of Section 13(d)(3) of the Exchange Act, comprised of the Reporting Persons, the Separately Filing Group Members and the Claure Parties.

Except as set forth below, all Items of this Schedule 13D, as amended prior to the date hereof, are materially unchanged. Capitalized terms used in this Amendment No. 15 and not otherwise defined shall have the respective meanings assigned to such terms in this Schedule 13D.

Item 3. Source and Amount of Funds or Other Consideration

This Item 3 is hereby amended and supplemented as follows:

The information set forth in Item 6 of this Schedule 13D is hereby incorporated by reference.

Item 4. Purpose of the Transaction

This Item 4 is hereby amended and supplemented as follows:

The information set forth in Item 6 of this Schedule 13D Amendment is hereby incorporated by reference.

Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer

This Item 6 is hereby amended and supplemented as follows:

On September 6, 2021, Deutsche Telekom entered into the 2021 Master Framework Agreement (the “2021 Master Framework Agreement”), by and among Deutsche Telekom, SoftBank and Project 6.

Pursuant to the terms of the 2021 Master Framework Agreement, Deutsche Telekom agreed that it will exercise its right to acquire 19,017,795 shares of Common Stock granted by Project 6 pursuant to the SB-DT Call Option, dated June 22, 2020 (which is filed as Exhibit 51 hereto) (the “Floating Options”) and its right to acquire 26,348,874 shares of Common Stock granted by Project 6 pursuant to the Replacement SB-Newco Call Option, dated October 6, 2020 (which is filed as Exhibit 57 hereto) (the “Fixed Options”).

Pursuant to the Call Option Support Agreement, dated June 22, 2020 (which is filed as Exhibit 54 hereto), Deutsche Telekom elected to settle the strike price with respect to the Floating Options and the Fixed Options in the form of no par value registered shares of Deutsche Telekom (“DT Shares”). Pursuant to the 2021 Master Framework Agreement, the exercise price with respect to the 19,017,795 Floating Options that will be exercised will be adjusted to equal 225,000,000 less the number of DT Shares issuable upon the exercise of the Fixed Options. In aggregate, Deutsche Telekom will issue to SoftBank a total of 225,000,000 DT Shares following closing of the option exercises. The exercise date of the Floating Options and Fixed Options will be the date that is two business days following the issuance of an audit report by an appointed auditor confirming a successful mandatory audit required under German law in connection with the issuance of the new DT Shares by Deutsche Telekom by utilizing its authorized capital.

The 2021 Master Framework Agreement also contains provisions pursuant to which Deutsche Telekom has agreed that it will prioritize the use of cash proceeds from certain potential divestitures to exercise additional fixed options under the Replacement SB-Newco Call Option and floating options under the SB-DT Call Option for cash, up to an aggregate of $2.4 billion of total exercise price, subject to certain conditions and provided that Deutsche Telekom is under no obligation to undertake any such divestitures.

Deutsche Telekom and Softbank have also agreed that in connection with specified future exercises of floating options under the SB-DT Call Option (other than the exercise of 19,017,795 Floating Options described above), the exercise price of the floating options will be the lesser of (i) the average of the daily VWAPs of the Common Stock for the 20 trading days beginning on, and including, the scheduled trading day immediately following the date of delivery of the notice of exercise and (ii) the average of the daily VWAPs of the Common Stock for (x) the period of 20 trading days immediately preceding the date of delivery of the notice of exercise and (y) the 20 trading days beginning on, and including, the scheduled trading day immediately following the date of delivery of the notice of exercise. The periods described in clauses (i) and (ii)(y) of the foregoing shall be subject to adjustment in certain circumstances.

Also in connection with the 2021 Master Framework Agreement, Deutsche Telekom has provided its consent under the Proxy Agreement for SoftBank to have additional flexibility to pledge its shares of Common Stock in connection with the entry into margin loans and other monetization transactions, provided that Deutsche Telekom will continue to have the right to direct the vote of such shares of Common Stock and such shares of Common Stock will continue to be subject to the terms of the remaining fixed options under Replacement SB-Newco Call Option and floating options under the SB-DT Call Option.

In addition, SoftBank has agreed to continue to waive certain rights it would have to transfer the remaining 4,800,000 shares of Common Stock that it holds that do not underlie the Call Options and up to 5,000,000 of SoftBank True-Up Shares, as defined in the Letter Agreement dated as of February 20, 2020 (which is filed as Exhibit 45 hereto) (to the extent the earnout targets are reached), and accordingly, those shares of Common Stock generally may not be transferred without Deutsche Telekom’s consent prior to April 1, 2024.

The foregoing summary of the 2021 Master Framework Agreement does not purport to be complete and is subject to, and qualified in its entirety by, the 2021 Master Framework Agreement, which is filed as Exhibit 24 hereto. Capitalized terms used in the foregoing description are used as defined in the 2021 Master Framework Agreement.

(a) If an Indemnified Party shall desire to assert any claim for indemnification provided for under this Article 5, including either first-party Claims for indemnification against SoftBank or DT, or any third-party Claims against such Indemnified Party, such Indemnified Party shall notify DT or SoftBank, as the case may be (the “Indemnifying Party”), in writing of such Claim, the amount or the estimated amount of damages sought thereunder to the extent then ascertainable (which estimate shall not be conclusive of the final amount of such Claim), any other remedy sought thereunder, any relevant time constraints relating thereto and, to the extent practicable, any other material details pertaining thereto (a “Claim Notice”) promptly after receipt by such Indemnified Party of written notice of the Claim, with simultaneous notice to all other Parties to this Framework Agreement; provided, however, that failure to provide a Claim Notice shall not affect the indemnification obligations provided hereunder except to the extent the Indemnifying Party shall have been materially prejudiced as a result of such failure. The Indemnified Party shall deliver to the Indemnifying Party, promptly after the Indemnified Party’s receipt thereof, copies of all notices and documents (including court papers) received by the Indemnified Party relating to the Claim; provided, however, that failure to provide any such copies shall not affect the indemnification obligations provided hereunder except to the extent the Indemnifying Party shall have been materially prejudiced as a result of such failure.

(b) The Indemnified Party shall have the right to conduct its own defense and select its own counsel (provided such counsel is nationally or regionally recognized) in connection with that defense. Where consistent with the interests of each party, the parties shall undertake commercially reasonable efforts to cooperate in the defense or prosecution thereof. Such cooperation shall include the retention and (upon any party’s request) the provision of records and information that are reasonably relevant to such Claim, and use of commercially reasonable efforts to make employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. The Indemnified Party shall not admit any liability with respect to, or settle, compromise or discharge, such Claim without the Indemnifying Party’s prior written consent (which consent shall not be unreasonably withheld, conditioned or delayed).

(e) If any Indemnified Party or any of its affiliates incurs or would incur any tax liability arising from the receipt or accrual of any payment received or to be received pursuant to this Article 5, then the amount of the payment payable by the Indemnifying Party shall be increased as necessary so that, after taking into account any such tax liability (including any tax liability arising from additional amounts payable under this provision, and disregarding any Tax Attributes (as defined in the Business Combination Agreement) of the Indemnified Party), the Indemnified Party receives (or retains) an amount equal to the amount it would have received (or retained) had no such tax liability arisen.
