In connection with the Exchange Offers, T-Mobile also solicited consents (the “Consent Solicitations”) from holders of the USCC Notes to, among other things, modify or eliminate certain notice requirements and restrictive covenants in the USCC Existing Indentures (as defined below) (the “Proposed Amendments”). Withdrawal rights in connection with the Exchange Offers and the Consent Solicitations expired at 5:00 p.m., New York City time, on June 13, 2025, which was the withdrawal deadline for the Exchange Offers and the Consent Solicitations. As of the withdrawal deadline, T-Mobile has received valid consents to the Proposed Amendments from the holders of at least a majority of the outstanding aggregate principal amount of each series of the USCC Notes. On June 17, 2025, USCC entered into:

(a)the twelfth supplemental indenture, dated as of June 17, 2025 (the “USCC Twelfth Supplemental Indenture”), between USCC and The Bank of New York Mellon Trust Company, N.A. (formerly known as The Bank of New York Trust Company, N.A., as successor to BNY Midwest Trust Company), as trustee (the “Trustee”), to the indenture, dated as of June 1, 2002 (the “USCC Base Indenture”), as supplemented by the Third Supplemental Indenture, dated as of December 3, 2003 (the “Third Supplemental Indenture”) and the Fifth Supplemental Indenture, dated as of June 21, 2004 (the “Fifth Supplemental Indenture”) relating to the USCC 2033 Notes;

(b)the thirteenth supplemental indenture, dated as of June 17, 2025 (the “USCC Thirteenth Supplemental Indenture”), between USCC and the Trustee, to the USCC Base Indenture, as supplemented by the Ninth Supplemental Indenture, dated as of August 12, 2020 (the “Ninth Supplemental Indenture”) relating to the USCC 2069 Notes;

(c)the fourteenth supplemental indenture, dated as of June 17, 2025 (the “USCC Fourteenth Supplemental Indenture”), between USCC and the Trustee, to the USCC Base Indenture, as supplemented by the Tenth Supplemental Indenture, dated as of December 2, 2020 (the “Tenth Supplemental Indenture”) relating to the USCC March 2070 Notes; and

(d)the fifteenth supplemental indenture, dated as of June 17, 2025 (the “USCC Fifteenth Supplemental Indenture” and together with the USCC Twelfth Supplemental Indenture, the USCC Thirteenth Supplemental Indenture and the USCC Fourteenth Supplemental Indenture, the “USCC Supplemental Indentures”), between USCC and the Trustee, to the USCC Base Indenture, as supplemented by the Eleventh Supplemental Indenture, dated as of May 17, 2021 (the “Eleventh Supplemental Indenture” and collectively with the Third Supplemental Indenture, the Fifth Supplemental Indenture, the Ninth Supplemental Indenture, the Tenth Supplemental Indenture and the USCC Base Indenture, the “USCC Existing Indentures”) relating to the USCC June 2070 Notes.

The USCC Supplemental Indentures provide that (a) the amendments to the USCC Existing Indentures contained therein will not become operative until the date on which the previously announced sale of USCC’s wireless operations to T-Mobile US, Inc. (the “Acquisition”) closes and (b) if the settlement date with respect to the issuance of the New T-Mobile Notes has not occurred within five business days following the date on which the Acquisition closes, the amendments previously effected shall be deemed null and void as if they had not occurred. Pursuant to the USCC Supplemental Indentures, the following sections or provisions (among others) under the USCC Existing Indentures will be deleted, modified or amended:

•Section 3.02 (Action to Redeem Securities) of the USCC Base Indenture, Exhibit A (Form of 6.70% Senior Notes due 2033) to the Third Supplemental Indenture and the Fifth Supplemental Indenture, Section 2.4 (Optional Redemption) of the Ninth Supplemental Indenture, Section 2.4 (Optional Redemption) of the Tenth Supplemental Indenture and Section 2.4 (Optional Redemption) of the Eleventh Supplemental Indenture will be modified to significantly reduce the notice period set forth in such provisions in connection with a redemption of the applicable USCC Notes thereunder;

•Sections 4.02 (Maintenance of Office or Agency for Payment, Registration, Transfer and Exchange of Securities), 4.03 (Paying Agent), 4.04 (Appointment to Fill Vacancy in Office of Trustee), 4.05 (Restriction on Consolidation, Merger of the Company), 4.06 (Original Issue Discount Security), 5.01 (Company to Furnish Trustee Information as to Names and Addresses of Securityholders) and 5.03 (Delivery Obligations of Company) of the USCC Base Indenture will be deleted;

•Sections 10.01 (Consolidations or Mergers of Company and Sales or Conveyances of Property of Company), 10.02 (Successor to Company) and 10.03 (Opinion of Counsel) of the USCC Base Indenture will be deleted;

•Sections 3.1 (Limitations on Secured Debt) and 3.2 (Limitation on Sale and Leaseback) of the Third Supplemental Indenture, the Fifth Supplemental Indenture, the USCC Supplemental Indenture, the Tenth Supplemental Indenture and the Eleventh Supplemental Indenture will be deleted; and
