MetroPCS Reports Second Quarter 2010 Results

Record Adjusted EBITDA and Record Second Quarter Net Subscriber Additions

Second Quarter 2010 Highlights Include:

DALLAS (August 5, 2010) – MetroPCS Communications, Inc. (NYSE: PCS), the nation’s leading provider of unlimited, flat-rate wireless communications service with no annual contract, today announced financial and operational results for the quarter ended June 30, 2010. MetroPCS reported growth in quarterly consolidated Adjusted EBITDA of approximately 38% over the second quarter 2009 and finished the second quarter 2010 with over 7.6 million subscribers.

“The outstanding operational and financial results for the second quarter were primarily a result of strong net subscriber additions and lower churn primarily driven by continued acceptance of our Wireless for All plans. Strong operational results and net subscriber growth of approximately 1.4 million subscribers over the past 12 months resulted in record consolidated Adjusted EBITDA for the company of over $322 million, up approximately 38% from the second quarter 2009. We continue to build our 4G LTE network, and we are currently testing in selected metropolitan areas. We are on track for our initial 4G LTE launch in selected metropolitan areas in the second half of this year. Our goal is to provide our pay-in-advance subscribers a 4G experience equivalent to that which will be enjoyed by traditional post-pay customers,” said Roger D. Linquist, Chairman, President and Chief Executive Officer of MetroPCS.

“Our Wireless for All unlimited text/talk/Web tax-inclusive plans provide unparalleled value for the U.S. consumer. Our handset line-up is strong, highlighted by a number of Smartphones and QWERTY keyboard handsets and we are focused on introducing additional Smartphones and QWERTY handsets to our line-up. With our low cost structure, strong CDMA network, current service offerings and the anticipated launch of our 4G LTE network, we believe we are very well-positioned as a full service broadband wireless provider,” Linquist concluded.

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.

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. ARPU for the six months ended June 30, 2010 includes approximately $0.8 million and ARPU for the three and six months ended June 30, 2009 includes $24.7 million, respectively, that would have been recognized as service revenues but were classified as equipment revenues because the consideration received from customers was less than the fair value of promotionally priced handsets. 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 providers. Equipment revenues related to new customers, adjusted for the impact to service revenues of promotional activity, 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 Company’s 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 — The Company utilizes 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. The Company believes investors use CPU primarily as a tool to track changes in the Company’s non-selling cash costs over time and to compare the Company’s non-selling cash costs to those of other wireless providers, although other wireless carriers may calculate this measure differently. 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, divided by the sum of the average monthly number of customers during such period. 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 income plus depreciation 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 MetroPCS minus interest 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. Other wireless carriers may calculate consolidated Adjusted EBITDA differently. 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. In addition, consolidated Adjusted EBITDA is also utilized, among other measures, to determine management’s compensation under their annual cash performance awards. 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.
