Quarterly Consolidated Results

• MetroPCS reported consolidated service revenues of approximately $727 million for the first quarter, an increase of 29% when compared to the prior year first quarter.

• Income from operations increased $19 million, or 17%, for the quarter ended March 31, 2009 as compared to the prior year’s first quarter. This was due primarily to an increase in total revenues of approximately $133 million and an approximately $25 million gain on disposal of assets partially offset by higher cost of service of $57 million, higher selling, general and administrative expenses of $32 million, higher cost of equipment of approximately $25 million and higher depreciation and amortization of $24 million.

• Consolidated Adjusted EBITDA of $199 million increased by $21 million, or approximately 12%, when compared to the same period in the previous year.

• Average revenue per user (ARPU) of $40.40 for the quarter represents a decrease of $2.11 when compared to the first quarter of 2008 and a decrease of $0.12 when compared to the fourth quarter of 2008. The change in ARPU from the fourth quarter of 2008 is primarily attributable to a decrease in MetroFlash revenue by consumers purchasing $49 handsets versus re-flashing existing handsets.

• The Company’s cost per gross addition (CPGA) of $134.23 for the quarter represents an increase of $9.23 when compared to the prior year’s first quarter and primarily was driven by an increase in marketing and advertising expenses due to the launch of service in the New York City and Boston metropolitan areas.

• Cost per user (CPU) decreased to $16.69 in the first quarter, or approximately 12%, when compared to the first quarter of 2008. The change in CPU is primarily due to the Company’s continued scaling of the business, partially offset by expenses related to the launch of service and ramp up of operations in the Northeast Markets.

• Churn increased from 4% to 5%, when compared to the first quarter of 2008. One of the key drivers of the increase in churn were incremental gross additions of 857 thousand during the nine months ended December 31, 2008, as compared to the same period in 2007.

Effective January 1, 2009, the Company implemented a change to the composition of its reportable segments under SFAS No. 131“Disclosure About Segments of an Enterprise and Related Information.” Under this change, the Company now aggregates its thirteen operating segments as follows: the Core Markets include the Atlanta, Dallas/Ft. Worth, Detroit, Las Vegas, Los Angeles, Miami, Orlando/Jacksonville, Sacramento, San Francisco, and Tampa/Sarasota metropolitan areas and the Northeast Markets include the Boston, New York and Philadelphia metropolitan areas. The historical quarterly information presented below has been restated to reflect this change.

Definition of Terms and Reconciliation of Non-GAAP Financial Measures

The Company utilizes certain financial measures and key performance indicators that are not calculated in accordance with GAAP to assess our financial and operating performance. A non-GAAP financial measure is defined as a numerical measure of a company’s financial performance that (i) excludes amounts, or is subject to adjustments that have the effect of excluding amounts, that are included in the comparable measure calculated and presented in accordance with GAAP in the statement of income or statement of cash flows; or (ii) includes amounts, or is subject to adjustments that have the effect of including amounts, that are excluded from the comparable measure so calculated and presented.

Average revenue per user, or ARPU, cost per gross addition, or CPGA, and cost per user, or CPU, are non-GAAP financial measures utilized by the Company’s management to judge the Company’s ability to meet its liquidity requirements and to evaluate its operating performance. Management believes that these measures are important in understanding the performance of the Company’s operations from period to period, and although every company in the wireless industry does not define each of these measures in precisely the same way, management believes that these measures (which are common in the wireless industry) facilitate key liquidity and operating performance comparisons with other companies in the wireless industry. The following tables reconcile non-GAAP financial measures with the Company’s financial statements presented in accordance with GAAP.

Page 10 of 13

ARPU — The Company utilizes ARPU to evaluate per-customer service revenue realization and to assist in forecasting future service revenues. ARPU is calculated exclusive of pass through charges that the Company collects from its customers and remits to the appropriate government agencies.

Average number of customers for any measurement period is determined by dividing (a) the sum of the average monthly number of customers for the measurement period by (b) the number of months in such period. Average monthly number of customers for any month represents the sum of the number of customers on the first day of the month and the last day of the month divided by two. The following table shows the calculation of ARPU for the periods indicated.

CPGA — The Company utilizes CPGA to assess the efficiency of its distribution strategy, validate the initial capital invested in its customers and determine the number of months to recover customer acquisition costs. This measure also allows management to compare the Company’s average acquisition costs per new customer to those of other wireless broadband PCS providers. Equipment revenues related to new customers are deducted from selling expenses in this calculation as they represent amounts paid by customers at the time their service is activated that reduce the acquisition cost of those customers. Additionally, equipment costs associated with existing customers, net of related revenues, are excluded as this measure is intended to reflect only the acquisition costs related to new customers. The following table reconciles total costs used in the calculation of CPGA to selling expenses, which the Company considers to be the most directly comparable GAAP financial measure to CPGA.

CPU — CPU is cost of service and general and administrative costs (excluding applicable non-cash stock-based compensation expense included in cost of service and general and administrative expense) plus net loss on equipment transactions unrelated to initial customer acquisition exclusive of pass through charges, divided by the sum of the average monthly number of customers during such period. CPU does not include any depreciation and amortization expense. Management uses CPU as a tool to evaluate the non-selling cash expenses associated with ongoing business operations on a per customer basis, to track changes in these non-selling cash costs over time, and to help evaluate how changes in the Company’s business operations affect non-selling cash costs per customer. In addition, CPU provides management with a useful measure to compare our non-selling cash costs per customer with those of other wireless providers. We believe investors use CPU primarily as a tool to track changes in our non-selling cash costs over time and to compare our non-selling cash costs to those of other wireless providers. Other wireless carriers may calculate this measure differently. The following table reconciles total costs used in the calculation of CPU to cost of service, which we consider to be the most directly comparable GAAP financial measure to CPU.

The Company’s senior secured credit facility calculates consolidated Adjusted EBITDA as: consolidated net incomeplusdepreciation and amortization; gain (loss) on disposal of assets; non-cash expenses; gain (loss) on extinguishment of debt; provision for income taxes; interest expense; and certain expenses of MetroPCSminusinterest and other income and non-cash items increasing consolidated net income. The Company considers Adjusted EBITDA, as defined above, to be an important indicator to investors because it provides information related to the Company’s ability to provide cash flows to meet future debt service, capital expenditures and working capital requirements and fund future growth. The Company presents Adjusted EBITDA because covenants in its senior secured credit facility contain ratios based on this measure. If the Company’s Adjusted EBITDA were to decline below certain levels, covenants in the Company’s senior secured credit facility that are based on Adjusted EBITDA, including the maximum senior secured leverage ratio covenant, may be violated and could cause, among other things, an inability to incur further indebtedness and in certain circumstances a default or mandatory prepayment under the Company’s senior secured credit facility. The Company’s maximum senior secured leverage ratio is required to be less than 4.5 to 1.0 based on Adjusted EBITDA plus the impact of certain new markets. The lenders under the senior secured credit facility use the senior secured leverage ratio to measure the Company’s ability to meet its obligations on its senior secured debt by comparing the total amount of such debt to its Adjusted EBITDA, which the Company’s lenders use to estimate its cash flow from operations. The senior secured leverage ratio is calculated as the ratio of senior secured indebtedness to Adjusted EBITDA, as defined by the senior secured credit facility. Adjusted EBITDA is not a measure calculated in accordance with GAAP, and should not be considered a substitute for, operating income (loss), net income (loss), or any other measure of financial performance reported in accordance with GAAP. In addition, Adjusted EBITDA should not be construed as an alternative to, or more meaningful than cash flows from operating activities, as determined in accordance with GAAP.

The following table shows the calculation of our consolidated Adjusted EBITDA, as defined in the Company’s senior secured credit facility, for the three months ended March 31, 2009 and 2008.
