1 In accordance with applicable SEC rules, since Messrs. Legere and Sievert both served as Chief Executive Officer during 2020, they are each included in the table above and corresponding footnotes as a PEO. Accordingly, the PEOs and Non-PEO NEOs for the applicable years were as follows:

Year	PEO	Non-PEO NEOs
2024	G. Michael Sievert	Peter Osvaldik, Mark W. Nelson, Michael J. Katz, Jonathan A. Freier, Callie R. Field
2023	G. Michael Sievert	Peter Osvaldik, Mark W. Nelson, Michael J. Katz, Jonathan A. Freier, Callie R. Field
2022	G. Michael Sievert	Peter Osvaldik, Neville R. Ray, Mark W. Nelson, Peter A. Ewens, Brandon D. Draper
2021	G. Michael Sievert	Peter Osvaldik, Neville R. Ray, Mark W. Nelson, Peter A. Ewens, David A. Miller
2020	G. Michael Sievert & John J. Legere	Peter Osvaldik, Neville R. Ray, Peter A. Ewens, David A. Miller, David R. Carey

2 The Summary Compensation Table totals reported for the PEOs and the average of the Non-PEO NEOs for each fiscal year were subject to the following adjustments per Item 402(v)(2)(iii) of Regulation S-K to calculate “Compensation Actually Paid”:

	2024
	Mr. Sievert ($)			Average Non-PEO NEOs ($)
Summary Compensation Table Total		30,040,245			9,778,552

Increase for Fair Value of Awards Granted during Prior Fiscal Year that Remained Outstanding and Unvested as of Applicable Fiscal Year End, determined based on change in ASC 718 Fair Value from Prior Fiscal Year End to Applicable Fiscal Year End		30,039,861			6,736,393
Deduction/Increase in Fair Value of Awards Granted during Prior Fiscal Year that Vested During Applicable Fiscal Year, determined based on change in ASC 718 Fair Value from Prior Fiscal Year End to Vesting Date		(48,959	)		936,639
TOTAL ADJUSTMENTS		40,150,434			10,683,573
Compensation Actually Paid		70,190,679			20,462,125

3 “Compensation Actually Paid” excludes the Stock Awards column from the relevant fiscal year’s Summary Compensation Table total. The equity values utilized in determining “Compensation Actually Paid” instead reflect the aggregate of the following components, as applicable: (i) the fair value as of the end of the listed fiscal year of unvested equity awards granted in that year; (ii) the change in fair value during the listed fiscal year of equity awards granted in prior years that remained outstanding and unvested at the end of the listed fiscal year; and (iii) the change in fair value during the listed fiscal year through the vesting date of equity awards granted in prior years that vested during the listed fiscal year, less the fair value at the end of the prior year of awards granted prior to the listed fiscal year that failed to meet applicable vesting conditions during the listed fiscal year. Equity values are calculated in accordance with ASC Topic 718, and the valuation assumptions used to calculate fair values did not materially differ from those disclosed at the time of the grant. For additional information regarding the valuation assumptions used to calculate the fair value of our equity awards, please see the notes to our financial statements in our Annual Report on Form 10-K for the applicable fiscal year.

4 TMUS Total Shareholder Return represents cumulative TSR on a fixed investment of $100 in our common stock for the period beginning on the last trading day of 2019 through the end of the relevant fiscal year, assuming reinvestment of all dividends. Peer Group TSR represents the cumulative TSR on a fixed investment of $100 (the “Peer Group TSR”) of the Dow Jones U.S. Telecommunications Index for the period beginning on the last trading day of 2019 through the end of the relevant fiscal year, assuming reinvestment of all dividends. The values included in the columns titled “Compensation Actually Paid” to our PEO and the Non-PEO NEOs, calculated in accordance with SEC disclosure rules, in each of the fiscal years reported above and over the four-year cumulative period shows how the compensation awarded fluctuated year-over-year, primarily based on our stock price as of the last day of the listed fiscal year, among other factors.

5 The Company has identified Adjusted Free Cash Flow as the company-selected measure for the pay versus performance disclosure, as it represents the most important financial performance measure used to link compensation actually paid to the PEO and the Non-PEO NEOs in 2024 to the Company’s performance. For the year ended December 31, 2020, Adjusted Free Cash Flow excluded gross payments for the settlement of interest rate swaps. See Appendix A to this Proxy Statement for a reconciliation of Adjusted Free Cash Flow, and Adjusted Free Cash Flow, excluding gross payments for the settlement of interest rate swaps, non-GAAP measures, to the most directly comparable GAAP measure.

Compensation Actually Paid vs. Total Shareholder Return

Relationship Between Compensation Actually Paid to Mr. Sievert and the Average of the Compensation Actually Paid to the Non-PEO NEOs and the Company’s Cumulative TSR. From 2020 to 2024, the compensation actually paid to our PEO and the average of the compensation actually paid to the Non-PEO NEOs decreased by 51% and 44%, respectively, compared to a 187% increase in our TSR over the same time period.

Compensation Actually Paid vs. Net Income

Relationship Between Compensation Actually Paid to Mr. Sievert and the Average of the Compensation Actually Paid to the Non-PEO NEOs and the Company’s Net Income. From 2020 to 2024, the compensation actually paid to our PEO and the average of the compensation actually paid to the Non-PEO NEOs decreased by 51% and 44%, respectively, compared to a 270% increase in our Net Income over the same time period.

Compensation Actually Paid vs. Company Selected Measure

Relationship Between Compensation Actually Paid to Mr. Sievert and the Average of the Compensation Actually Paid to the Non-PEO NEOs and the Company’s Adjusted Free Cash Flow. From 2020 to 2024, the compensation actually paid to our PEO and the average of the compensation actually paid to the Non-PEO NEOs decreased by 51% and 44%, respectively, compared to a 468% increase in our Adjusted Free Cash Flow over the same time period.

Total Shareholder Return Vs Peer Group

Relationship Between the Company’s TSR and the Peer Group TSR. Peer Group TSR increased by 9% from 2020 to 2024 as compared to the Company’s TSR, which increased by 187% over the same time period. As the values change considerably from year-to-year based on stock price performance, they further demonstrate the “pay-for-performance” compensation philosophy of our executive compensation program. As the table demonstrates, the compensation of our PEO and the Non-PEO NEOs is higher when our stock price performs well, and lower when the stock price does not perform as well, demonstrating the clear alignment of interests of our PEO and the Non-PEO NEOs and our stockholders.

Tabular List, Table

PAY VERSUS PERFORMANCE TABULAR LIST

We believe the following performance measures represent the most important financial performance measures used by us to link compensation actually paid to our NEOs for the fiscal year ended December 31, 2024:

Service Revenue;

Core Adjusted EBITDA; and

Adjusted Free Cash Flow.

In the “Compensation Discussion and Analysis” section of this Proxy Statement, we provide greater detail on the elements of our executive compensation program and our “pay-for-performance” compensation philosophy. We believe the Company’s executive compensation program appropriately rewards our PEO and the Non-PEO NEOs for Company and individual performance, promotes retention of our senior leadership team and supports long-term value creation for our stockholders.
