•Cash purchases of property and equipment, including capitalized interest, are expected to be between $12.1 billion to $12.3 billion, an increase from the prior guidance of $12.0 billion to $12.3 billion.

•Merger-related costs are expected to be between $2.8 billion and $3.0 billion before taxes. These costs are excluded from Core Adjusted EBITDA but will impact Net income, Net cash provided from operating activities and Free Cash Flow.

•Net cash provided by operating activities, including payments for Merger-related costs, is expected to be between $13.9 billion and $14.0 billion, an increase from prior guidance of $13.6 billion to $13.9 billion.

Core Adjusted EBITDA should not be used to predict Net income as the difference between this measure and Net income is variable.

(2)Management uses Core Adjusted EBITDA as a measure to monitor the financial performance of our operations, excluding the impact of lease revenues from our related device financing programs. Our guidance ranges assume a continued reduction in lease revenues to between $3.3 billion and $3.5 billion for 2021.

(3)Merger-related costs are excluded from Core Adjusted EBITDA but will impact Net income, Net cash provided by operating activities and Free Cash Flow.

(4)Capital expenditures means cash purchases of property and equipment, including capitalized interest.

Reconciliation of Non-GAAP Financial Measures to GAAP Financial Measures

(Unaudited)

This Press Release includes non-GAAP financial measures. The non-GAAP financial measures should be considered in addition to, but not as a substitute for, the information provided in accordance with GAAP. Reconciliations for the non-GAAP financial measures to the most directly comparable GAAP financial measures are provided below. T-Mobile is not able to forecast Net income on a forward-looking basis without unreasonable efforts due to the high variability and difficulty in predicting certain items that affect GAAP net income including, but not limited to, Income tax expense, stock-based compensation expense and Interest expense. Adjusted EBITDA and Core Adjusted EBITDA should not be used to predict Net income as the difference between either of these measures and Net income is variable.

The following table includes the impact of the Sprint merger on a prospective basis from the close date of April 1, 2020. Historical results prior to April 1, 2020 have not been restated and reflect standalone T-Mobile.

Adjusted EBITDA and Core Adjusted EBITDA are reconciled to Net income as follows:

(1)Following the Prepaid Transaction, starting on July 1, 2020, we provide MVNO services to DISH. We have included the operating income from discontinued operations, for periods prior to the Prepaid Transaction, in our determination of Adjusted EBITDA to reflect EBITDA contributions of the Prepaid Business that has been replaced by the MVNO Agreement beginning on July 1, 2020, in order to enable management, analysts and investors to better assess ongoing operating performance and trends.

(2)Stock-based compensation includes payroll tax impacts and may not agree to stock-based compensation expense in the consolidated financial statements. Additionally, certain stock-based compensation expenses associated with the Sprint merger have been included in Merger-related costs.

(3)Supplemental employee payroll, third-party commissions and cleaning-related COVID-19-related costs were not significant for Q3 2020, Q4 2020, Q1 2021, Q2 2021 and Q3 2021.

(4)Other, net may not agree to the Condensed Consolidated Statements of Comprehensive Income, primarily due to certain non-routine operating activities, such as other special items that would not be expected to reoccur or are not reflective of T-Mobile's ongoing operating performance, and are therefore excluded from Adjusted EBITDA and Core Adjusted EBITDA.

Adjusted EBITDA - Earnings before Interest expense, net of Interest income, Income tax expense, Depreciation and amortization expense, Stock-based compensation and certain expenses not reflective of T-Mobile's ongoing operating performance, such as Merger-related costs, COVID-19-related costs and Impairment expense. Core Adjusted EBITDA represents Adjusted EBITDA less lease revenues. Core Adjusted EBITDA and Adjusted EBITDA are non-GAAP financial measures utilized by T-Mobile's management to monitor the financial performance of our operations. T-Mobile uses Core Adjusted EBITDA and Adjusted EBITDA as benchmarks to evaluate T-Mobile's operating performance in comparison to its competitors. T-Mobile also uses

7

Adjusted EBITDA internally as a measure to evaluate and compensate its personnel and management for their performance. Management believes analysts and investors use Core Adjusted EBITDA and Adjusted EBITDA as supplemental measures to evaluate overall operating performance and facilitate comparisons with other wireless communications companies because they are indicative of T-Mobile's ongoing operating performance and trends by excluding the impact of Interest expense from financing, non-cash depreciation and amortization from capital investments, stock-based compensation, Merger-related costs including network decommissioning costs, incremental costs directly attributable to COVID-19 and impairment expense, as they are not indicative of T-Mobile's ongoing operating performance, as well as certain other nonrecurring income and expenses. Management believes analysts and investors use Core Adjusted EBITDA because it normalizes for the transition in the company's device financing strategy, by excluding the impact of lease revenues from Adjusted EBITDA, to align with the related depreciation expense on leased devices, which is excluded from the definition of Adjusted EBITDA. Core Adjusted EBITDA and Adjusted EBITDA have limitations as analytical tools and should not be considered in isolation or as a substitute for Net income or any other measure of financial performance reported in accordance with U.S. Generally Accepted Accounting Principles ("GAAP").
