“Keeping our costs down through efficient spending and intelligent network builds are at the very foundation of the MetroPCS operating philosophy, and have contributed to the sixth consecutive quarter of increasing Consolidated Adjusted EBITDA,” added Linquist.

Consolidated Comparison of Quarter Ended June 2007 versus Quarter Ended June 2006

MetroPCS reported a 56% increase in service revenues of $171 million that was primarily attributable to the net addition of approximately 1.1 million subscribers since last year’s second quarter and the migration of existing subscribers to higher priced service plans. Equipment revenues increased by $12 million, or 19% for the quarter primarily as a result of the sale of higher priced handsets and higher gross subscriber additions.

Income from operations increased $78 million, or 144% for the quarter ended June 2007 as compared to the prior year’s quarter. This was in part due to an increase in total revenues of $183 million, which was offset by a higher cost of service of $55 million and higher cost of equipment of $21 million, both of which were related primarily to the increase in total subscribers, the sale of new handsets to existing subscribers, and the launch of several expansion markets during 2006. Selling, general and administrative expenses increased $22 million for the quarter and was primarily related to supporting the company’s growth. Depreciation and amortization increased by $9 million for the quarter due to a larger amount of property, plant and equipment in service, both in the Core and Expansion Markets. Consolidated Adjusted EBITDA of $180 million increased $89 million when compared to the same period in the previous year.

Average revenue per user (ARPU) increased $0.32 in the second quarter compared to last year’s quarter. The company’s cost per gross addition (CPGA) of $124.79 for the quarter remained relatively flat compared to the prior year’s second quarter and continues to be among the lowest in the wireless industry. The reduction in the cost per user (CPU) of 9% from the second quarter of 2006 demonstrates the company’s ability to scale the business and generate substantial operating cash flow.

Income from operations increased $37 million, or 38% for the quarter ended June 30, 2007 as compared to the prior year’s quarter. This was in part due to the increase in total revenues of $79 million which was offset by a higher cost of service of $29 million and higher cost of equipment of $7 million, both of which were related primarily to the increase in total subscribers in the Core Markets. Higher selling, general and administrative expenses of $6 million were primarily a result of supporting the subscriber growth since June 30, 2006.

Expansion Markets Comparison of Quarter Ended June 2007 versus Quarter Ended June 2006

The Expansion Markets’ rapid growth of subscribers has continued with over 1 million subscribers as of June 30, 2007, which represents an increase in penetration of covered population of 4.0% over the prior year’s second quarter. The additional 708 thousand subscribers that were acquired since June 30, 2006, as well as migration of existing customers to higher price service plans, resulted in an increase in

service revenues of $96 million as well as an increase in equipment revenues of $8 million for the quarter as compared to the same quarter a year ago.

Loss from operations decreased $41 million, or 93% for the quarter ended June 30, 2007 as compared to the prior year’s second quarter. This was in part due to the increase in total revenues of $104 million which was offset by a higher cost of service of $26 million and higher cost of equipment of $14 million, both of which were related primarily to growth in the Expansion Markets’ subscriber base and the sale of new handsets to existing subscribers. Higher selling, general and administrative expenses of $16 million were primarily the result of supporting the subscriber growth of 236% since June 30, 2006. The Expansion Markets generated an Adjusted EBITDA of $12 million for the quarter versus an Adjusted EBITDA deficit of $36 million a year ago.

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 activation revenues, as these amounts are a component of costs of acquiring new customers and are included in the calculation of CPGA. ARPU is also calculated exclusive of E-911, FUSF and vendor’s compensation charges, as these are generally 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.

	Three Months						Six Months

ARPU	$	43.18		$	42.86		$	43.46		$	42.98

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. Activation revenues and 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.

CPGA	$	124.79		$	122.20		$	115.87		$	114.56

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 (which includes the gain or loss on sale of handsets to existing customers and costs associated with handset replacements and repairs (other than warranty costs which are the responsibility of the handset manufacturers)) exclusive of E-911, FUSF and vendor’s

compensation 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 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 Communications 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. 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, net income, 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 and six months ended June 30, 2007 and 2006.
