(1)Adjusted EBITDA, Core Adjusted EBITDA and Free Cash Flow are non-GAAP financial measures. These 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 these non-GAAP financial measures to the most directly comparable GAAP financial measures are provided in the Reconciliation of Non-GAAP Financial Measures to GAAP Financial Measures tables. We are 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 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 the two measures and Net Income is variable.

Total Postpaid Net Additions
(in thousands)
chart-b4e8b766d9d34611bc51.jpg


Postpaid phone net customer additions were 773 thousand in Q1 2021, compared to 824 thousand in Q4 2020 and 452 thousand in Q1 2020.
Sequentially, the decrease was primarily due to lower gross customer additions driven by seasonality, partially offset by lower churn.
Year-over-year, the increase was primarily due to expanded retail presence as a result of the Merger and increased retail store traffic due to closures arising from the COVID-19 pandemic (the “Pandemic”) in the prior period, as well as increased growth from T-Mobile for Business, partially offset by higher churn from customers acquired in the Merger.
Postpaid other net customer additions were 437 thousand in Q1 2021, compared to 794 thousand in Q4 2020 and 325 thousand in Q1 2020.
Sequentially, the decrease was primarily due to lower additions in the public and educational sector, as well as higher churn.
Year-over-year, the increase was primarily due to expanded retail presence as a result of the Merger, higher gross additions from connected devices, increased retail store traffic due to closures arising from the Pandemic in the prior year period and lower churn.    
Total postpaid net customer additions were 1.2 million in Q1 2021, compared to 1.6 million in Q4 2020 and 777 thousand in Q1 2020.
The postpaid upgrade rate was approximately 4.8% in Q1 2021, compared to 5.7% in Q4 2020 and 3.8% in Q1 2020.


Postpaid phone churn was 0.98% in Q1 2021, down 5 basis points from 1.03% in Q4 2020 and up 12 basis points from 0.86% in Q1 2020.
Sequentially, the decrease was primarily due to continued network improvement, and the continued enhancement of the value proposition and network experience of Sprint customers.
Year-over-year, the increase was primarily driven by the inclusion of the customer base acquired in the Merger with higher churn.

chart-708df182a1fa41fbb031.jpg

Postpaid phone ARPU was $47.30 in Q1 2021, down 1.2% from $47.86 in Q4 2020 and up 3.3% from $45.80 in Q1 2020.
Sequentially, the decrease was primarily due to lower recurring charges from customers acquired in the Merger including from the impact of rate plan migrations, an increase in average customers per account and a decrease in late and restore fees associated with improved collections activity.
Year-over-year, the increase was primarily due to the net impact of customers acquired in the Merger, which have higher ARPU, and higher premium service revenues, partially offset by ongoing promotional activity.





Total postpaid accounts were 26.0 million at the end of Q1 2021, compared to 25.8 million at the end of Q4 2020 and 15.2 million at the end of Q1 2020.

Sequentially, postpaid ARPA was essentially flat. A decrease in late and restore fees associated with improved collections activity, lower recurring charges from customers acquired in the Merger including rate plan migrations and ongoing promotional activity were mostly offset by an increase in average customers per account.
Year-over-year, the increase was primarily due to an increase in customers per account, including further penetration in connected devices, higher premium service revenues, and the net impact of customers acquired in the Merger, partially offset by ongoing promotional activity.

(in thousands)
chart-ae0239fb55e7484086a1.jpg

Prepaid net customer additions were 151 thousand in Q1 2021, compared to net additions of 84 thousand in Q4 2020 and net losses of 128 thousand in Q1 2020.
Sequentially and year-over-year, the increase was primarily due to lower churn.
Migrations to postpaid plans reduced prepaid net customer additions in Q1 2021 by approximately 170 thousand, up from 165 thousand in Q4 2020 and 115 thousand in Q1 2020.
Prepaid churn was 2.78% in Q1 2021, compared to 2.92% in Q4 2020 and 3.52% in Q1 2020.
Sequentially and year-over-year, the decrease was primarily due to lower switching activity and the improved quality of recently acquired customers.
Prepaid ARPU was $37.81 in Q1 2021, down 0.7% from $38.08 in Q4 2020 and down 0.8% from $38.11 in Q1 2020, primarily driven by ongoing promotional activities.

Service Revenues
($ in millions)
chart-1cba586c3c084518b291.jpg
Service revenues were $14.2 billion in Q1 2021, essentially flat compared to $14.2 billion in Q4 2020 and up 60% from $8.8 billion in Q1 2020.
Sequentially, an increase in Postpaid service revenues was partially offset by seasonally lower Wholesale revenues.
Year-over-year, the increase was primarily due to an increase in Postpaid service revenues, primarily due to customers acquired in the Merger and continued Postpaid customer growth, an increase in Wholesale revenues primarily driven by our Master Network Service Agreement with DISH, which went into effect on July 1, 2020, and higher Roaming and other service revenues, primarily from the inclusion of wireline and Lifeline operations acquired in the Merger.

Equipment revenues were $5.3 billion in Q1 2021, down 10% from $6.0 billion in Q4 2020 and up 153% from $2.1 billion in Q1 2020. Lease revenues included in equipment revenues were $1.0 billion in Q1 2021 compared to $1.2 billion in Q4 2020 and $165 million in Q1 2020.
Sequentially, the decrease was primarily due to:
A decrease in the number of devices sold, driven by seasonality and iconic device launches in the prior quarter;
Lower average revenue per device sold, excluding purchased leased devices, driven by a decrease in the high-end device mix; and
A decrease in lease revenues due to the continued planned shift in device financing from leasing to equipment installation plans.
Year-over-year, the increase was primarily due to:
An increase in the number of devices sold, excluding purchased leased devices, due to an increased customer base as the result of the Merger;
Higher average revenue per device sold, excluding purchased leased devices, due to an increase in the high-end device mix primarily driven by a larger postpaid customer base as a result of the Merger;
An increase in lease revenues due to a higher number of customer devices under lease, primarily from leases acquired in the Merger; and
An increase in purchased leased devices, primarily due to a larger base of leased devices as a result of the Merger.

Cost of Services, exclusive of D&A
($ in millions, % of Service revs excl. Merger-related costs)
chart-e426849f5ef14a39a961.jpg







Cost of services, exclusive of depreciation and amortization (D&A), was $3.4 billion in Q1 2021, down 12% from $3.8 billion in Q4 2020 and up 106% from $1.6 billion in Q1 2020.
Sequentially, the decrease was primarily due to lower Merger-related costs in the current quarter, as well as higher realized Merger synergies, which were partially offset by increased costs related to site upgrades.
Year-over-year, the increase was primarily due to an increase in expenses associated with leases, backhaul agreements, other network expenses, the continued build-out of our nationwide 5G network, and higher employee-related and benefit-related costs, primarily due to the Merger.
Merger-related costs primarily related to incremental costs associated with network decommissioning and integration were $136 million in Q1 2021 compared to $527 million in Q4 2020 and $0 in Q1 2020.
As a percentage of Service revenues, Cost of Services, exclusive of D&A, and excluding Merger-related costs, decreased by 40 basis points sequentially, and increased by 440 basis points year-over-year.



Cost of equipment sales, exclusive of D&A, was $5.1 billion in Q1 2021, down 12% from $5.8 billion in Q4 2020 and up 103% from $2.5 billion in Q1 2020.
Sequentially, the decrease was primarily due to:
A decrease in the number of devices sold, driven by seasonality and iconic device launches in the prior quarter; and
A lower average cost per device sold, excluding purchased leased devices, primarily driven by a decrease in the high-end device mix.
Year-over-year, the increase was primarily due to:
An increase in the number of devices sold, excluding purchased leased devices, primarily due to an increased customer base as a result of the Merger;
A higher average cost per device sold, excluding purchased leased devices, primarily driven by an increase in the high-end device mix, primarily driven by a larger postpaid customer base as a result of the Merger; and
An increase in purchased leased devices, primarily due to a larger base of leased devices as a result of the Merger.

Selling, General and Administrative (SG&A) Expense
($ in millions, % of Service revs excl. Merger-related and COVID-19-related costs)
chart-f755c4d033554a24a251.jpg
Selling, general and administrative (SG&A) expense was $4.8 billion in Q1 2021, essentially flat compared to $4.8 billion in Q4 2020 and up 30% from $3.7 billion in Q1 2020.
Sequentially, the slight increase was primarily driven by higher employee-related costs, including expenses associated with annual stock-based compensation vesting, which were mostly offset by lower bad debt expense and Merger synergies realized.
Year-over-year, the increase was primarily due to higher external labor and professional services, advertising, lease expense and employee-related costs, primarily from the Merger, as well as higher commission expense, primarily due to higher gross customer additions, partially offset by lower bad debt expense.
Supplemental employee payroll, third-party commissions and cleaning-related COVID-19 costs were insignificant in Q1 2021 and Q4 2020 and $117 million in Q1 2020.

Merger-related costs were $145 million in Q1 2021 compared to $153 million in Q4 2020 and $143 million in Q1 2020.
As a percentage of Service revenues, SG&A expense, excluding Merger-related and COVID-19-related costs, increased 30 basis points sequentially and decreased 600 basis points year-over-year.
Total bad debt expense and losses from sales of receivables (reported within SG&A expense) was $64 million in Q1 2021, compared to $112 million in Q4 2020 and $138 million in Q1 2020. As a percentage of Total revenues, total bad debt expense and losses from sales of receivables was 0.32% in Q1 2021, compared to 0.55% in Q4 2020 and 1.24% in Q1 2020.





D&A was $4.3 billion in Q1 2021, up 2% from $4.2 billion in Q4 2020 and up 150% from $1.7 billion in Q1 2020. This includes D&A related to Leased devices of $897 million in Q1 2021, compared to $982 million in Q4 2020 and $163 million in Q1 2020.
Sequentially, the increase was primarily driven by higher depreciation expense from the continued build-out of our nationwide 5G network, partially offset by lower depreciation expense on leased devices resulting from a lower total number of customer devices under lease.
Year-over-year, the increase was primarily due to higher depreciation expense from assets acquired in the Merger, excluding leased devices, and network expansion from the continued build-out of our nationwide 5G network, higher depreciation expense on leased devices, primarily due to a larger base of leased devices as a result of the Merger and higher amortization from intangible assets acquired in the Merger.

Net income was $933 million in Q1 2021, up 24% from $750 million in Q4 2020 and down 2% from $951 million in Q1 2020. Diluted EPS was $0.74 in Q1 2021, up from $0.60 in Q4 2020 and down from $1.10 in Q1 2020.
Sequentially, the increase in Net income and diluted EPS was primarily due to lower Cost of equipment sales and Cost of services, partially offset by lower Equipment revenues and higher Income tax expense.
Year-over-year, the decrease in Net income was driven by higher Cost of equipment sales, D&A, Cost of services, SG&A and interest expense, partially offset by higher Service and Equipment revenues. Diluted EPS also decreased due to an increase in outstanding shares as a result of the Merger.
Net income and diluted EPS, respectively, were impacted by Merger-related costs, net of tax, for Q1 2021 of $220 million and $0.18, compared to $506 million and $0.40 in Q4 2020 and $117 million and $0.14 in Q1 2020.
Net income margin was 6.6% in Q1 2021, compared to 5.3% in Q4 2020 and 10.8% in Q1 2020. Net income margin is calculated as Net income divided by Service revenues.

Core Adjusted EBITDA was $5.9 billion in Q1 2021, up 7% from $5.5 billion in Q4 2020 and up 68% from $3.5 billion in Q1 2020.
Sequentially, the increase was primarily due to lower Cost of equipment sales and lower Cost of services, excluding Merger-related costs, partially offset by lower Equipment revenues, excluding lease revenues, and higher SG&A expense, excluding Merger-related costs.
Year-over-year, the increase was primarily due to higher Service revenues and Equipment revenues, excluding lease revenues, partially offset by higher Cost of equipment sales, higher Cost of services, both excluding Merger-related costs, and higher SG&A expense, excluding Merger-related and COVID-related costs.
Core Adjusted EBITDA excludes Merger-related costs of $298 million in Q1 2021 compared to $686 million in Q4 2020 and $143 million in Q1 2020, as well as COVID-related costs of $117 million in Q1 2020.
Core Adjusted EBITDA margin was 41.3% in Q1 2021, compared to 38.8% in Q4 2020 and 39.6% in Q1 2020.



Net cash provided by operating activities was $3.7 billion in Q1 2021, compared to $3.5 billion in Q4 2020 and $1.6 billion in Q1 2020.
Sequentially, the increase was primarily due to an increase in Net income, adjusted for non-cash income and expenses, partially offset by an increase in net cash outflows from changes in working capital. The change in working capital was primarily due to higher use of cash from Accounts payable and accrued liabilities and Other current and long-term liabilities, mostly offset by lower use of cash from Accounts and Equipment installment plan receivables, Inventories and Other current and long-term assets.
Year-over-year, the increase was primarily due to an increase in Net income, adjusted for non-cash income and expense, partially offset by an increase in net cash outflows from changes in working capital.

(1)We are 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. Core Adjusted EBITDA should not be used to predict Net income as the difference between these measures 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 $3.7 to $3.9 billion for 2021.
(3)Capital expenditures means cash purchases of property and equipment, including capitalized interest.
(4)Merger-related costs are excluded from Core Adjusted EBITDA but will impact Net income and cash flows.
(5)Free Cash Flow guidance does not assume any material net cash inflows from securitization in 2021.

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

This Investor Factbook 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 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 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 (as defined below), starting on July 1, 2020, we provide MVNO services to DISH. We have included the operating income from discontinued operations in our determination of the Adjusted EBITDA to reflect 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 Condensed 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 costs were not significant for Q3 and Q4 2020 and Q1 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 in Adjusted EBITDA and Core Adjusted EBITDA.

LTM Adjusted EBITDA and LTM Core Adjusted EBITDA reflect combined company results of New T-Mobile for Q1 2021, Q4 2020, Q3 2020 and Q2 2020 and standalone T-Mobile for prior periods. To illustrate the twelve month results of the combined company as if the Merger had closed on January 1, 2019, we have presented pro forma LTM Adjusted EBITDA and pro forma LTM Core Adjusted EBITDA ratios through December 31, 2020. Pro forma LTM Adjusted EBITDA for the LTM period ended December 31, 2020 is calculated as the sum of Q4 2020, Q3 2020 and Q2 2020 actual Adjusted EBITDA of $6.7 billion, $7.1 billion and $7.0 billion, respectively, plus the pro forma Adjusted EBITDA from Q1 2020 of $6.7 billion. Pro forma LTM Core Adjusted EBITDA for the LTM period ended December 31, 2020 is calculated as the sum of Q4 2020, Q3 2020 and Q2 2020 actual Core Adjusted EBITDA of $5.5 billion, $5.8 billion and $5.6 billion plus the pro forma Core Adjusted EBITDA from Q1 2020 of $5.2 billion. The same method applies to pro forma LTM Adjusted EBITDA and pro forma LTM Core Adjusted EBITDA for the LTM periods ended September 30 and June 30, 2020. These metrics are provided for illustrative purposes only and do not purport to represent what the actual consolidated results would have been had the Merger actually occurred on the date indicated, nor do they purport to project the future consolidated results of operations or consolidated financial condition for any future period or as of any future date. Additional information regarding pro forma adjustments is provided in Pro Forma Income Statement Metrics within this Investor Factbook. LTM Adjusted EBITDA and LTM Core Adjusted EBITDA for Q1 2021 represent the sum of actual Adjusted EBITDA and Core Adjusted EBITDA, respectively, for Q2 2020, Q3 2020, Q4 2020, and Q1 2021 and were not prepared on a pro forma basis.

Pro Forma Income Statement Metrics
(Unaudited)

The following tables present certain income statement metrics on a pro forma basis as though the Merger had been completed on January 1, 2019. The unaudited pro forma income statement metrics have been prepared in accordance with Article 11 of Regulation S-X (“Article 11”) which is a different basis than the unaudited pro forma financial information included in Note 2 - Business Combinations in our Annual Report on Form 10-K for the year ended December 31, 2020. The primary difference between the Article 11 pro forma financial information and the ASC 805 pro forma financial information prepared by us is the treatment of certain one-time transaction costs, which are removed from all periods under Article 11 but are recognized as if they had been incurred in their entirety during Q1 2019 under ASC 805. The unaudited pro forma income statement metrics are provided for illustrative purposes only and do not purport to represent what the actual consolidated results of operations or consolidated financial condition would have been had the Merger actually occurred on the date indicated, nor do they purport to project the future consolidated results of operations or consolidated financial condition for any future period or as of any future date. For the purposes of this section, “Combined” means the summation of historically reported standalone GAAP amounts of T-Mobile and Sprint. “Pro forma adjustments” means adjustments to combined metrics to give effect to matters that are directly attributable to the Merger, factually supportable, and expected to have a continuing impact on the results of the combined company. “Pro forma” metrics are those that have been adjusted as required for the presentation of Article 11 pro forma information.

We are presenting the pro forma metrics for the three months ended September 30, 2019, December 31, 2019 and March 31, 2020 to support the reconciliation of our LTM pro forma Adjusted EBITDA and pro forma Core Adjusted EBITDA calculations included in the Reconciliation of Non-GAAP Financial Measures to GAAP Financial Measures of this presentation.

Definitions of Terms

Operating and financial measures are utilized by T-Mobile’s management to evaluate its operating performance and, in certain cases, its ability to meet liquidity requirements. Although companies in the wireless industry may not define measures in precisely the same way, T-Mobile believes the measures facilitate key operating performance comparisons with other companies in the wireless industry to provide management, investors and analysts with useful information to assess and evaluate past performance and assist in forecasting future performance.
1.Customer - SIM number with a unique T-Mobile mobile identifier which is associated with an account that generates revenue. Customers generally are qualified either for postpaid service, where they generally pay after incurring service, or prepaid service, where they generally pay in advance.
2.Churn - The number of customers whose service was disconnected as a percentage of the average number of customers during the specified period further divided by the number of months in the period. The number of customers whose service was disconnected is presented net of customers that subsequently have their service restored within a certain period of time.
3.Customers per account - The number of postpaid customers as of the end of the period divided by the number of postpaid accounts as of the end of the period. An account may include postpaid phone, mobile broadband, and DIGITS customers.
4.Average Revenue Per Account (ARPA) - Average monthly postpaid service revenue earned per account. Postpaid service revenues for the specified period divided by the average number of postpaid accounts during the period, further divided by the number of months in the period.
Average Revenue Per User (ARPU) - Average monthly service revenue earned from customers. Service revenues for the specified period divided by the average number of customers during the period, further divided by the number of months in the period.
Postpaid phone ARPU excludes postpaid other customers and related revenues.
Service revenues - Postpaid, including handset insurance, prepaid, wholesale, and roaming and other service revenues.
5.Cost of services - Costs directly attributable to providing wireless service through the operation of T-Mobile’s network, including direct switch and cell site costs, such as rent, network access and transport costs, utilities, maintenance, associated labor costs, long distance costs, regulatory program costs, roaming fees paid to other carriers and data content costs.
Cost of equipment sales - Costs of devices and accessories sold to customers and dealers, device costs to fulfill insurance and warranty claims, write-downs of inventory related to shrinkage and obsolescence, and shipping and handling costs.
Selling, general and administrative expenses - Costs not directly attributable to providing wireless service for the operation of sales, customer care and corporate activities. These include all commissions paid to dealers and retail employees for activations and upgrades, labor and facilities costs associated with retail sales force and administrative space, marketing and promotional costs, customer support and billing, bad debt expense and administrative support activities.
6.Net income margin - Net income margin % calculated as net income divided by service revenues.
7.Adjusted EBITDA and Core Adjusted EBITDA - Adjusted EBITDA represents 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 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 income from operations, Net income or any other measure of financial performance reported in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”).
8.Adjusted EBITDA Margin and Core Adjusted EBITDA Margin - Adjusted EBITDA margin % calculated as Adjusted EBITDA divided by service revenues. Core Adjusted EBITDA margin % calculated as Core Adjusted EBITDA divided by service revenues.
9.Free Cash Flow - Net cash provided by operating activities less cash purchases of property and equipment, including proceeds from sales of tower sites and proceeds related to beneficial interests in securitization transactions and less cash payments for debt prepayment or debt extinguishment costs. Free Cash Flow is utilized by T-Mobile’s management, investors, and analysts to evaluate cash available to pay debt and provide further investment in the business. The reconciliation of Free Cash Flow to net cash provided by operating activities is detailed in the Reconciliation of Non-GAAP Financial Measures to GAAP Financial Measures schedule.
10.Net debt - Short-term debt, short-term debt to affiliates, long-term debt, and long-term debt (excluding tower obligations) to affiliates, short-term financing lease liabilities and financing lease liabilities, less cash and cash equivalents.
