Item 5.02 Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

On September 6, 2023, T-Mobile US, Inc. (the “Company”) entered into a letter agreement (the “Ewens Letter Agreement”) with Peter Ewens, the Company’s Executive Vice President, Corporate Strategy & Development, setting forth certain benefits Mr. Ewens will be entitled to receive from the Company upon his retirement on February 1, 2024. When Mr. Ewens retires, he will be entitled to receive the following (subject to his timely execution and non-revocation of a release of claims in favor of the Company and continued compliance with certain restrictive covenants):

• a prorated portion of his annual short-term incentive award for the 2024 calendar year, based on target performance and prorated based on the number of days he is employed by the Company during such calendar year;

• his outstanding and unvested time-based restricted stock units (“RSUs”) shall remain outstanding and shall continue to vest and be paid in accordance with the terms of the applicable award agreements;

• his outstanding and unvested performance-based RSUs (“PRSUs”) shall remain outstanding and shall continue to vest and be paid in accordance with the terms of the applicable award agreements, with the number of PRSUs earned based on the lesser of (i) actual performance during the full performance period or (ii) actual performance during the portion of the performance period ending on the retirement date;

• Company-paid group medical and dental benefits for up to 18 months following retirement; and

• continued eligibility for the Company’s employee mobile service discount program.

Upon Mr. Ewens’ death or disability following his retirement, but prior to the last date on which any RSUs or PRSUs become vested in accordance with the Ewens Letter Agreement, his then-outstanding and unvested RSUs and PRSUs will vest in full (without pro-ration) as of the date of his death or disability, with the number of PRSUs earned based on target performance.

In addition, pursuant to the Ewens Letter Agreement, no additional RSUs or PRSUs will be granted to Mr. Ewens following the date of the Ewens Letter Agreement.

The Ewens Letter Agreement provides that Mr. Ewens must continue to comply with certain restrictive covenants for 12 months following his retirement date (or, if later, the last date on which any RSUs or PRSUs vest in accordance with the terms of the Ewens Letter Agreement).

The foregoing description of the Ewens Letter Agreement is qualified in its entirety by the full text of the Ewens Letter Agreement, a copy of which will be subsequently filed with the U.S. Securities and Exchange Commission.
