KIRKLAND, Wash. – Feb. 24, 2010 – Clearwire Corporation (NASDAQ: CLWR) (along with its subsidiaries, “Clearwire” or the “Company”), a leading provider of wireless broadband services, today reported its consolidated financial and operating results for the fourth quarter and full year ended December 31, 2009.

“Over the past year, Clearwire established its leadership in 4G mobile broadband services by building the largest 4G network in North America, raising additional financing to fuel our growth, supporting the 4G wholesale service launches for three of the most prominent communications companies in the U.S., and delivering solid financial results in a challenging economic environment,” said Bill Morrow, CEO of Clearwire.

“Our all-IP network and unmatched spectrum holdings have truly enabled us to become the 4G ‘network of networks.’ We now provide the underlying capability to Comcast, Sprint, and Time Warner Cable to serve the growing demand for mobile broadband

services, and we are well positioned to expand our wholesale business even further. When coupled with the success of our own CLEAR retail brand, record subscriber growth, and our extensive market build plans for this year, we are confident that we remain on a strong growth trajectory for 2010.”

Business Outlook

In 2010, the Company expects to cover up to 120 million people with its 4G network. Within this footprint, services will be offered under both the CLEAR brand name, and that of the Company’s strategic wholesale providers which will vary across individual markets. The launches are expected to include top 100 markets such as New York, Boston, Washington, D.C., Houston, the San Francisco Bay Area, Denver, Minneapolis, and Kansas City.

During this year, the Company anticipates 4G subscriber levels to triple. The Company also expects retail cost-per-gross add (CPGA) to remain consistent with 2009 levels due to a significant number of market launches. In addition, the Company expects retail average-revenue-per-user (ARPU) to remain flat. The Company currently expects to have full year 2010 net cash spend between $2.8 billion to $3.2 billion.

The Company’s current and future plans are subject to a number of conditions and uncertainties, including among others, its ability to manage ongoing market development activities, its performance in launched markets and access to additional funding.

Presentation of 2009 Fourth Quarter, Year End and Pro Forma 2008 Fourth Quarter and Year End Results

As previously disclosed, on November 28, 2008, Clearwire, Sprint Nextel Corporation, Comcast Corporation, Time Warner Cable, Inc., Bright House Networks, LLC, Google Inc., and Intel Capital completed the transactions contemplated by the Transaction Agreement and Plan of Merger (the “Transaction Agreement”), entered into by the parties on May 7, 2008. For accounting purposes, the transactions (the “Transactions”) are treated as a “reverse acquisition” with the WiMAX business contributed from Sprint (the “Sprint WiMAX Business”) deemed to be the accounting acquirer. As a result, the financial results of the legacy Clearwire Corporation (“Old Clearwire”) prior to the consummation of the Transactions are not included as part of the Company’s consolidated financial statements. The results for Clearwire for the three and twelve months ended December 31, 2009, are presented with the results of operations of the Sprint WiMAX Business for the three and twelve months ended December 31, 2008, on subsequent pages of this earnings release.

In order to facilitate the most useful comparative analysis between periods, the following table summarizes Clearwire’s fourth quarter and year to date ended December 31, 2009, consolidated results versus the Pro Forma Financial Data for the comparable three and twelve month periods ended December 31, 2008. The Pro Forma Financial Data has been derived from the unaudited pro forma condensed combined statements of operations of Clearwire for the three and twelve months ended December 31, 2008. The unaudited pro forma condensed combined statements of operations of Clearwire give effect to the

Transactions as if they were consummated on January 1, 2008, and are based upon the financial results for both Old Clearwire and the Sprint WiMAX Business for the relevant periods. A full presentation of the unaudited pro forma condensed combined statements of operations for the three and twelve months ended December 31, 2008, and accompanying notes, are provided on subsequent pages of this release. The unaudited pro forma condensed combined statements of operations are presented for illustrative purposes only and are not necessarily indicative of the results of operations that would have been obtained had the Transactions actually been consummated on January 1, 2008, nor are they intended to be a projection of future results of operations. The unaudited pro forma condensed combined statements of operations do not give effect to the offering of the senior secured notes and the additional equity investments that occurred in November 2009, or the rights offering commenced in December 2009, or the application of the net proceeds from these transactions.

2009 Fourth Quarter and Year End Consolidated Results

Consolidated revenue increased by 34 percent to $79.9 million in the fourth quarter 2009, versus pro forma revenue of $59.7 million for the same quarter of 2008. The growth in revenue was driven primarily by Clearwire’s larger subscriber base, including the addition of ten new markets year-over-year.

Total subscribers increased to approximately 688,000 at the end of the fourth quarter of 2009, up from approximately 475,000 on a pro forma basis at the end of the fourth quarter 2008. Total retail subscribers in the Company’s 27 4G markets (both new markets and legacy markets recently upgraded to 4G service) were approximately 392,000 at the end of December. On a consolidated basis Clearwire added approximately 87,000 net new retail subscribers during the fourth quarter of 2009, more than the first three quarters combined. This fourth quarter increase included the addition of approximately 90,000 net new retail subscribers in the Company’s 27 4G markets, which were partially offset by a modest net decline in subscribers in domestic and international legacy markets for the quarter.

Retail ARPU for the fourth quarter of 2009 was $39.86, an increase of $0.16 from the $39.70 pro forma retail ARPU level from the prior year fourth quarter and a sequential quarter increase of $0.15 compared to $39.71 reported in the third quarter of 2009. Retail ARPU increased due to an increase in bundled sales and mobile offerings, offset by an increase in promotional activity due to the large number of new customers.

Cost of goods and services and network costs for the fourth quarter ended December 31, 2009, increased 119 percent to $169.8 million compared to pro forma cost of goods and services and network costs of $77.4 million in the fourth quarter of the prior year period. This increase is due to increased tower rents as the Company expands its 4G network, combined with more equipment sales to customers and approximately $41 million related to write offs of customer premise equipment and network and base station equipment, and an increase in obsolescence and shrinkage allowance.

Selling, General and Administrative (SG&A) expense increased to $201.1 million in the fourth quarter 2009 compared to pro forma expense of $109.7 million for the fourth quarter 2008 as a result of significantly greater gross and net adds in 4G markets than the prior years. In addition, headcount growth impacted fourth quarter 2009 SG&A expense compared to the fourth quarter 2008. Ending headcount at December 31, 2009 was approximately 3,440 compared to 1,635 employees at December 31, 2008.

Adjusted EBITDA for the fourth quarter of 2009 reflected a loss of $295.7 million, versus a similar pro forma Adjusted EBITDA loss of $151.0 million for the same period in 2008.

Higher network expansion activities led to an increase in Capital Expenditures (or CapEx) to $767 million in the fourth quarter of 2009 from pro forma CapEx of $83 million in the same period in 2008. Approximately $200 million of the 2010 network

build costs were accelerated and pulled into 2009 CapEx spend. Cash spent on operations and CapEx was $823 million for the fourth quarter of 2009, and $1.97 billion for the twelve months ended December 31, 2009. This was offset by a net increase of approximately $2.7 billion in net capital raising in Q4’09. Clearwire ended December 2009 with cash and short-term investments of approximately $3.8 billion invested primarily in U.S. Treasury securities.

Forward Looking Statements

This release, and other written and oral statements made by Clearwire from time to time, contains forward-looking statements which are based on management’s current expectations and beliefs, as well as on a number of assumptions concerning future events made with information that is currently available. Forward-looking statements may include, without limitation, management’s expectations regarding: future financial and operating performance and financial condition; proposed transactions; network development and market launch plans; strategic plans and objectives; industry conditions; the strength of the balance sheet; and liquidity and financing needs. The words “will,” “would,” “may,” “should,” “estimate,” “project,” “forecast,” “intend,” “expect,” “believe,” “target,” “designed,” “plan” and similar expressions are intended to identify forward-looking statements. Readers are cautioned not to put undue reliance on such forward-looking statements, which are not a guarantee of performance and are subject to a number of uncertainties and other factors, many of which are outside of Clearwire’s control, which could cause actual results to differ materially and adversely from such statements. Some factors that could cause actual results to differ are:

	•		We are an early-stage company with a history of operating losses and we expect to continue to realize significant net losses for the foreseeable future.

	•		We regularly evaluate our plans, and we may elect to pursue new or alternative strategies which we believe would be beneficial to our business, including among other things, modifying the pace at which we build our 4G mobile broadband networks, augmenting our network coverage in markets we launch, changing our sales and marketing strategy and or acquiring additional spectrum.

	•		If our business fails to perform as we expect, or if we elect to pursue new plans or strategies, we may be required to raise substantial additional financing, and if we are unable to raise such financing on acceptable terms we may need to modify our plans accordingly.

	•		We may fail to realize all of the anticipated benefits of the transactions with Sprint and the strategic investors.

	•		We are committed to using commercially reasonable efforts to deploy wireless broadband networks based solely on mobile WiMAX technology, even if there are alternative technologies available in the future that are technologically superior or more cost effective.

	•		We currently depend on our commercial partners to develop and deliver the equipment for our legacy and mobile WiMAX networks.

	•		Many of our competitors are better established and have significantly greater resources, and may subsidize their competitive offerings with other products and services.

	•		Our substantial indebtedness and restrictive debt covenants could limit our financing options and liquidity position and may limit our ability to grow our business.

	•		Sprint Nextel Corporation owns a majority of our shares, resulting in Sprint holding a majority voting interest in the Company, and Sprint may have, or may develop in the future, interests that may diverge from other stockholders.

	•		Future sales of large blocks of our common stock may adversely impact our stock price.

For a more detailed description of the factors that could cause such a difference, please refer to Clearwire’s filings with the Securities and Exchange Commission, including the information under the heading “Risk Factors” in our Annual Report on Form 10-K filed on March 26, 2009 and our Quarterly Report on Form 10-Q filed on November 10, 2009. Clearwire assumes no obligation to update or supplement such forward-looking statements.

Notes to Clearwire Corporation
Unaudited Pro Forma Condensed Combined Statements of Operations

(1)

Basis of presentation

Sprint Nextel Corporation entered into an agreement with Old Clearwire to combine both of their next generation wireless broadband businesses to form a new independent company. On Closing, Old Clearwire and the Sprint WiMAX Business completed the combination to form Clearwire. The Transactions were accounted for as a reverse acquisition with the Sprint WiMAX Business deemed to be the accounting acquirer.

At the Closing, the Investors made an aggregate $3.2 billion capital contribution to Clearwire and its subsidiary, Clearwire Communications LLC. In exchange for the contribution of the Sprint WiMAX Business and their investments, as applicable, Google initially received 25,000,000 shares of Clearwire Class A common stock and Sprint and the other Investors received in aggregate 505,000,000 shares of Clearwire Class B common stock and an equivalent amount of Clearwire Communications Class B common interests. The number of shares of Clearwire Class A and B common stock and Clearwire Communications Class B common interests, as applicable, that the Investors were entitled to receive under the Transaction Agreement was subject to a post-closing adjustment based on the trading price of Clearwire Class A common stock on NASDAQ over 15 randomly-selected trading days during the 30-day period ending on the 90th day after the Closing, or February 26, 2009, (the “Adjustment Date”), with a floor of $17.00 per share and a cap of $23.00 per share. During the measurement period, Clearwire Class A common stock traded below $17.00 per share on NASDAQ, so on the Adjustment Date, we issued to the Investors an additional 4,411,765 shares of Clearwire Class A common stock and 23,823,529 shares of Clearwire Class B common stock and Clearwire Communications Class B common interests to reflect the $17.00 final price per share. Additionally, in accordance with the subscription agreement, on February 27, 2009, CW Investment Holdings LLC purchased 588,235 shares of Clearwire Class A common stock at $17.00 per share for a total investment of $10.0 million. For the purpose of determining the number of shares outstanding within the unaudited pro forma condensed combined statements of operations, we assumed that the additional shares and common interests issued to the Investors and CW Investment Holdings LLC on the Adjustment Date and February 27, 2009, respectively, were issued as of the Closing and that the Closing was consummated on January 1, 2008.

In connection with the integration of the Sprint WiMAX Business and Old Clearwire operations, we expect that certain non-recurring charges will be incurred. We also expect that certain synergies might be realized due to operating efficiencies or future revenue synergies expected to result from the Transactions. However, in preparing the unaudited pro forma condensed combined statements of operations, which give effect to the Transactions as if they were consummated on January 1, 2008, no pro forma adjustments have been reflected to consider any such costs or benefits.

(2)

Pro Forma Adjustments Related to Purchase Accounting and Other Non-recurring Charges for the Three and Twelve Months Ended December 31, 2008

The pro forma adjustments related to purchase accounting have been derived from the allocation of the purchase consideration to the identifiable tangible and intangible assets acquired and liabilities assumed of Old Clearwire, including the allocation of the excess of the estimated fair value of net assets acquired over the purchase price.

Article 11 of Regulation S-X requires that pro forma adjustments reflected in the unaudited pro forma condensed combined statements of operations are directly related to the transaction for which pro forma financial information is presented and have a continuing impact on the results of operations. Certain charges have been excluded in the unaudited pro forma condensed combined statements of operations as such charges were incurred in direct connection with or at the time of the Transactions and are not expected to have an ongoing impact on the results of operations after the Closing.

(a)

Represents the accelerated vesting of stock options for certain members of management upon the Closing, which resulted in a one-time charge of approximately $38.9 million recorded by Old Clearwire in its historical financial statements for the 2 months and 11 months ended November 28, 2008. As these are non-recurring charges directly attributable to the Transactions, they are excluded from the unaudited pro forma condensed combined statements of operations.

(b)

Represents adjustments in the depreciation expense on a pro forma basis related to items of Old Clearwire property, plant and equipment that are being depreciated over their estimated remaining useful lives on a straight-line basis. The reduction in depreciation expense results from a decrease in the carrying value of Old Clearwire property, plant equipment due to the allocation of the excess of the estimated fair value of net assets acquired over the purchase price used in purchase accounting for the Transactions.

(c)

Represents adjustments to record amortization on a pro forma basis related to Old Clearwire spectrum lease contracts and other intangible assets over their estimated weighted average remaining useful lives on a straight-line basis. The increase in the amortization expense results from an increase in the carrying value of the Old Clearwire spectrum lease contracts and other intangible assets resulting from purchase accounting.

(d)

Represents the elimination of intercompany other income and related expenses associated with the historical agreements pre-Closing between the Sprint WiMAX Business and Old Clearwire, where Old Clearwire leased spectrum licenses from the Sprint WiMAX Business. The other income and related expenses were $466,000 and $2.6 million for the three and twelve months ended December 31, 2008, respectively.

(e)

Represents the reversal of transaction costs of $33.4 million and $48.6 million for the three and twelve months ended December 31, 2008, respectively, comprised of $27.4 million and $33.4 million of investment banking fees and $6.0 million and $15.2 million of other professional fees, recorded in the Old Clearwire historical financial

statements for the three and twelve months ended December 31, 2008, respectively. As these are non-recurring charges directly attributable to the Transactions, they are excluded from the unaudited pro forma condensed combined statements of operations for the three and twelve months ended December 31, 2008.

(f)

Prior to the Closing, Sprint leased spectrum to Old Clearwire through various spectrum lease agreements. As part of the Transactions, Sprint contributed both the spectrum lease agreements and the spectrum assets underlying those agreements. As a result of the Transactions, the spectrum lease agreements were effectively terminated, and the settlement of those agreements was accounted for as a separate element from the business combination. A settlement loss of $80.6 million resulted from the termination as the agreements were considered to be unfavorable to Clearwire relative to current market rates. This one-time charge recorded by Clearwire at the closing is excluded from the unaudited pro forma condensed combined statements of operations.

(g)

Prior to the Closing, Old Clearwire refinanced the Senior Term Loan Facility and renegotiated the loan terms. Historical interest expense related to the Senior Term Loan Facility before the refinancing and amortization of the deferred financing fees recorded by Old Clearwire, in the amount of $15.4 million and $94.1 million for the three and twelve months ended December 31, 2008, respectively, have been reversed as if the Transactions were consummated on January 1, 2008.

(h)		Represents the adjustment to record pro forma interest expense assuming the senior term loan facility, including the Sprint Pre-Closing financing (as defined in the Transaction Agreement) under the Amended Credit Agreement (as defined below), was outstanding as of January 1, 2008. The Closing would have resulted in an event of default under the terms of the credit agreement underlying the Senior Term Loan Facility unless the consent of the lenders was obtained. On November 21, 2008, Old Clearwire entered into the Amended and Restated Credit Agreement with the lenders to obtain their consent and to satisfy other conditions to closing under the Transaction Agreement (the “Amended Credit Agreement”). The Amended Credit Agreement resulted in additional fees to be paid and adjustments to the underlying interest rates. The Sprint Pre-Closing Financing was assumed by Clearwire on the Closing, as a result of the financing of the Sprint WiMAX Business operations by Sprint for the period from April 1, 2008, through the Closing, and added as an additional tranche of term loans under the Amended Credit Agreement.

		Pro forma interest expense was calculated over the period using the effective interest method resulting in an adjustment of $32.6 million and $175.7 million for the three and twelve months ended December 31, 2008, respectively, based on an effective interest rate of approximately 14.0 percent. Pro forma interest expense also reflects an adjustment to accrete the debt to par value. Pro forma interest expense was calculated based on the contractual terms under the Amended Credit Agreement, assuming a term equal to its contractual maturity of 30 months and the underlying interest rate was the LIBOR loan base rate of 2.75 percent, as the 3 month LIBOR rate in effect at the Closing was less than the base rate, plus the applicable margin. The calculation assumed an applicable margin of 6.00 percent and additional rate increases as specified in the Amended Credit Agreement over the term of the loan. A one-eighth

		percentage change in the interest rate would increase or decrease interest expense by $295,000 and $1.6 million for the three and twelve months ended December 31, 2008, respectively. Total interest expense on a pro forma basis does not include an adjustment for capitalized interest.

(i)		Represents the adjustment to reflect the pro forma income tax expense for the three and twelve months ended December 31, 2008, which was determined by computing the pro forma effective tax rates for the three and twelve months ended December 31, 2008, giving effect to the Transactions. Clearwire expects to generate net operating losses into the foreseeable future and thus has recorded a valuation allowance for the deferred tax assets not expected to be realized. Therefore, for the three and twelve months ended December 31, 2008, no tax benefit was recognized.

(j)

Represents the allocation of a portion of the pro forma combined net loss to the non-controlling interests in consolidated subsidiaries based on Sprint’s and the Investors’ (other than Google) ownership of the Clearwire Communications Class B common interests upon Closing of the Transactions and reflects the contributions by CW Investment Holdings LLC and the Investors at $17.00 per share following the post-closing adjustment. This adjustment is based on pre-tax loss since income tax consequences associated with any loss allocated to the Clearwire Communications Class B common interests will be incurred directly by Sprint and the Investors (other than Google and CW Investment Holdings LLC).

(3)

Pro Forma Net Loss per Share

The Clearwire combined pro forma net loss per share presented below assumes the closing of the Transactions and that the Clearwire Class A and B common stock and Clearwire Communications Class B common interests issued to Sprint, the Investors and CW Investment Holdings LLC were outstanding from January 1, 2008, and reflects the resolution of the post-closing price adjustment at $17.00 per share. The shares of Clearwire Class B common stock have nominal equity rights. These shares have no right to dividends of Clearwire and no right to any proceeds on liquidation other than the par value of Clearwire Class B common stock.

The following table presents the pro forma number of Clearwire shares outstanding as if the Transactions had been consummated on January 1, 2008 (in thousands):


	Basic		Diluted
Clearwire Class A common stock held by existing stockholders(i)		164,484		164,484

Weighted average Clearwire Class A common stock outstanding		194,484		723,307


(i)		Shares outstanding related to Clearwire Class A common stock held by Clearwire stockholders has been derived from the sum of the number of shares of Old Clearwire Class A common stock and Old Clearwire Class B common stock issued and outstanding at November 28, 2008, and subject to conversion of each share of Old Clearwire Class A common stock and Old Clearwire Class B common stock into the right to receive one share of Clearwire Class A common stock. The basic weighted average shares outstanding related to Clearwire Class A common stock are the shares issued in the Transactions and assumed to be outstanding for the entire period for which loss per share is being calculated. The computation of pro forma diluted Clearwire Class A common stock did not include the effects of the following options, restricted stock units and warrants as the inclusion of these securities would have been anti-dilutive (in thousands):


	As of
	November 28,
	2008
Stock options		18,431
Warrants		17,806
Restricted stock units		1,238

		37,475


(ii)		Holders of Clearwire Class B common stock will be entitled at any time to exchange one share of Clearwire Class B common stock, in combination with one Clearwire Communications Class B common interest, for one share of Clearwire Class A common stock.

Shares of Clearwire Class B common stock have no impact on pro forma basic net loss per share because they do not participate in net income (loss) or distributions. However, the hypothetical exchange of Clearwire Communications Class B common interests together with Clearwire Class B common stock for Clearwire Class A common stock may have a dilutive effect on pro forma diluted loss per share due to certain tax effects. As previously mentioned, that exchange would result in a decrease to the non-controlling interests and a corresponding increase in net loss attributable to the Clearwire Class A common stock. Further, to the extent that all of the Clearwire Communications Class B common interests and Clearwire Class B common stock are converted to Clearwire Class A common stock on a pro forma basis, the partnership structure is assumed to no longer exist and Clearwire would be required to recognize a tax charge related to indefinite lived intangible assets. Net loss attributable to holders of Clearwire Class A common stock, assuming conversion of the Clearwire Communications Class B common interests and Clearwire Class B common stock, is as follows (in thousands):


	Three Months Ended			Twelve Months Ended

Definition of Terms and Reconciliation of Non-GAAP Financial Measures to Unaudited Consolidated Statements of Operations

The Company utilizes certain financial measures which are widely used in the telecommunications industry and are not calculated based on accounting principles generally accepted in the United States of America (GAAP). Certain of these financial measures are considered non-GAAP financial measures within the meaning of Item 10 of Regulation S-K promulgated by the SEC. Other companies may calculate these measures differently.

(1) Adjusted EBITDA is a non-GAAP financial measure. Adjusted EBITDA is defined as consolidated operating loss less depreciation and amortization expenses, non cash expenses related to capital assets (towers, spectrum leases and buildings) and stock-based compensation expense. A reconciliation of operating loss to Adjusted EBITDA is as follows:


	Unaudited Pro Forma						Unaudited Pro Forma
	Three months ended December 31,						Twelve months ended December 31,
(in thousands)	Actual			Pro Forma			Actual			Pro Forma
	2009			2008			2009			2008
Operating Loss	$	(417,664	)	$	(245,187	)	$	(1,183,343	)	$	(918,320	)

Non Cash Expenses
Spectrum Lease Expense		27,780			32,980			88,725			112,944
Tower & Building Rents		30,323			8,670			78,126			30,524
Stock Compensation		3,305			10,831			27,512			44,570

Non Cash Items Expense		61,408			52,481			194,363			188,038

Depreciation and amortization		60,513			41,670			208,263			128,602

ADJUSTED EBITDA		(295,743	)		(151,036	)		(780,717	)		(601,680	)


In a capital-intensive industry, management believes Adjusted EBITDA, as well as the associated percentage margin calculation, to be meaningful measures of the Company’s operating performance. We provide Adjusted EBITDA as a supplemental performance measure because management believes it facilitates comparisons of the Company’s operating performance from period to period and comparisons of the Company’s operating performance to that of other companies by backing out potential differences caused by non-cash expenses related to long-term capital assets and leases, and share-based compensation. Because Adjusted EBITDA facilitates internal comparisons of our historical operating performance, management also uses Adjusted EBITDA for business planning purposes and in measuring our performance relative to that of our competitors. In addition, we believe that Adjusted EBITDA and similar measures are widely used by investors, financial analysts and credit rating agencies as a measure of our financial performance over time and to compare our financial performance with that of other companies in our industry.

(2) Retail ARPU is revenue comprised of total revenue, less: acquired businesses revenue (revenue from entities that were acquired by Old Clearwire), the revenue generated from the sales of devices, shipping revenue, and wholesale revenue; divided by the average number of retail subscribers in the period divided by the number of months in the period.

Management uses retail ARPU to identify average revenue per retail customer, to track changes in average retail customer revenues over time, to help evaluate how changes in our business, including changes in our service offerings and fees, affect average revenue per retail customer, and to assist in forecasting future service revenue. In addition, retail ARPU provides management with a useful measure to compare our retail customer revenue to that of other wireless communications providers. We believe investors use retail ARPU primarily as a tool to track changes in our average revenue per retail

customer and to compare our per retail customer service revenues to those of other wireless communications providers.

(3) Retail Churn, which measures retail customer turnover, is calculated as the number of retail subscribers that terminate service in a given month divided by the average number of retail subscribers in that month using the actual number of retail subscribers or the pro forma number of retail subscribers, as applicable. Retail subscribers that discontinue service in the first 30 days of service for any reason, or in the first 90 days of service under certain circumstances, are deducted from our gross retail customer additions and therefore not included in the retail churn calculation.

Management uses retail churn to measure retention of our retail subscribers, to measure changes in customer retention over time, and to help evaluate how changes in our business affect customer retention. We believe investors use retail churn primarily as a tool to track changes in our customer retention. Other companies may calculate this measure differently.

(4) Retail CPGA (Cost per Gross Addition) is selling, general and administrative costs less general and administrative costs and acquired businesses costs, plus devices equipment subsidy, divided by gross retail customer additions in the period.

Management uses retail CPGA to measure the efficiency of our retail customer acquisition efforts, to track changes in our average cost of acquiring new retail subscribers over time, and to help evaluate how changes in our sales and distribution strategies affect the cost-efficiency of our customer acquisition efforts. We believe investors use retail CPGA primarily as a tool to track changes in our average cost of acquiring new subscribers.
