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 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.

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

Adjusted EBITDA represents earnings before Interest expense, net of Interest income, Income tax expense, Depreciation and amortization, stock-based compensation and certain expenses, gains and losses, which are not reflective of our ongoing operating performance (“Special Items”). Special Items include Merger-related costs (gain), net, (Gain) loss on disposal groups held for sale, certain legal-related recoveries and expenses, restructuring costs not directly attributable to the Merger (including severance), and other non-core gains and losses. Core Adjusted EBITDA represents Adjusted EBITDA less device 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 Core 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 to facilitate comparisons with other wireless communications services 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, non-cash stock-based compensation, and Special Items. 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 device 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 substitutes for Net income or any other measure of financial performance reported in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”).

T-Mobile US, Inc.

Reconciliation of Non-GAAP Financial Measures to GAAP Financial Measures (continued)

(Unaudited)

Adjusted Free Cash Flow is calculated as follows:

Adjusted Free Cash Flow - Net cash provided by operating activities less Cash purchases of property and equipment, plus Proceeds from sales of tower sites and Proceeds related to beneficial interests in securitization transactions. Adjusted Free Cash Flow is utilized by T-Mobile’s management, investors and analysts to evaluate cash available to pay debt, repurchase shares, pay dividends and provide further investment in the business.

Adjusted Free Cash Flow margin - Adjusted Free Cash Flow divided by Service revenues. Adjusted Free Cash Flow Margin is utilized by T-Mobile’s management, investors, and analysts to evaluate the company’s ability to convert service revenue efficiently into cash available to pay debt, repurchase shares and provide further investment in the business.

The current guidance range for Adjusted Free Cash Flow is calculated as follows:

The previous guidance range for Adjusted Free Cash Flow was calculated as follows:

T-Mobile US, Inc.
