CLEARWIRE CORPORATION AND SUBSIDIARIES
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (unaudited)
1. Description of Business and Basis of Presentation
     The Business
     The condensed consolidated financial statements include the accounts of Clearwire Corporation, a Delaware corporation, and our wholly-owned and majority-owned or controlled subsidiaries (collectively “Clearwire”). We were formed on October 27, 2003. We are an international provider of high speed wireless broadband services to individuals, small businesses, and others in a number of markets through our advanced network. As of June 30, 2008, we offered our services in 46 markets throughout the United States and four markets internationally.
     Business Segments
     We comply with the requirements of Statement of Financial Accounting Standards (“SFAS”) No. 131, Disclosures about Segments of an Enterprise and Related Information (“SFAS No. 131”), which establishes annual and interim reporting standards for an enterprise’s operating segments and related disclosures about its products, services, geographic areas and major customers. Operating segments are defined as components of an enterprise for which separate financial information is available that is evaluated regularly by the chief operating decision makers in deciding how to allocate resources and in assessing performance. Operating segments can be aggregated for segment reporting purposes so long as certain aggregation criteria are met. We define the chief operating decision makers as our Chief Executive Officer, Chief Operating Officer and Chief Financial Officer. See Note 15, Business Segments, for additional discussion.
     Basis of Presentation
     The accompanying condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). Certain information and note disclosures normally included in annual financial statements have been condensed or omitted for interim financial information in accordance with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. These unaudited condensed consolidated financial statements should be read in conjunction with the financial statements contained in our Annual Report on Form 10-K for the year ended December 31, 2007 (“Form 10-K”). In the opinion of management, these unaudited condensed consolidated financial statements reflect all adjustments, consisting of normal and recurring adjustments and accruals, necessary for a fair presentation of our financial condition, results of operations and cash flows for the periods presented.
     Principles of Consolidation — The condensed consolidated financial statements include all of the assets, liabilities and results of operations of our wholly-owned and majority-owned or controlled subsidiaries. Investments in entities that we do not control, but for which we have the ability to exercise significant influence over operating and financial policies, are accounted for under the equity method. All intercompany transactions are eliminated in consolidation.
     Use of Estimates — The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The estimates are based on historical experience, current conditions and various other assumptions believed to be reasonable under the circumstances. The estimates form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources, as well as identifying and assessing appropriate accrual and disclosure treatment with respect to commitments and contingencies. Actual results may differ materially from these estimates. To the extent that there are material differences between these estimates and actual results, the presentation of the financial condition or results of operations may be affected.

(continued)
     Significant estimates inherent in the preparation of the accompanying financial statements include the valuation of investments, the valuation of derivative instruments, allowance for doubtful accounts, depreciation, long-lived assets, goodwill and intangible assets, including spectrum, share-based compensation, and our deferred tax asset valuation allowance.
2. Significant Accounting Policies
     Significant Accounting Policies — Other than the adoption of SFAS No. 133, Accounting for Derivative Instruments and Hedging Activities (“SFAS No. 133”) and SFAS No. 157, Fair Value Measurements (“SFAS No. 157”), discussed below, there have been no significant changes in our significant accounting policies during the six months ended June 30, 2008 as compared to the significant accounting policies described in our Annual Report on Form 10-K for the year ended December 31, 2007.
     Derivative Instruments
     During the first quarter of 2008 we adopted SFAS No. 133 when we began hedging the LIBOR rate. SFAS No. 133, as amended and interpreted, establishes accounting and reporting standards for derivative instruments, including certain derivative instruments embedded in other contracts, and for hedging activities. As required by SFAS No. 133, we record all derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative and the resulting designation. Derivatives used to hedge the exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivatives used to hedge the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. To qualify for hedge accounting, we must comply with the detailed rules and strict documentation requirements at the inception of the hedge, and hedge effectiveness is assessed at inception and periodically throughout the life of each hedging relationship. Hedge ineffectiveness, if any, is also measured periodically throughout the life of the hedging relationship.
     In the normal course of business, we are exposed to the effect of interest rate changes. We have limited our exposure by adopting established risk management policies and procedures including the use of derivatives. It is our policy that derivative transactions are executed only to manage exposures arising in the normal course of business and not for the purpose of creating speculative positions or trading.
     All derivatives are recorded at fair value on the balance sheet as either assets or liabilities. Each derivative is designated as either a cash flow hedge or a fair value hedge, or remains undesignated. Currently, we only have derivatives that are designated as cash flow hedges and which are effective. Changes in the fair value of derivatives that are designated and effective as cash flow hedges are recorded in other comprehensive income and reclassified to the statement of operations when the effects of the item being hedged are recognized.
     All designated hedges are formally documented as to the relationship with the hedged item as well as the risk management strategy. Both at inception and on an ongoing basis, the hedging instrument is assessed as to its effectiveness. If and when a derivative is determined not to be highly effective as a hedge, or the underlying hedged transaction is no longer likely to occur, or the derivative is terminated, any changes in the derivative’s fair value, that will not be effective as an offset to the income effects of the item being hedged, will be recognized currently in the statement of operations.
     To determine the fair value of derivative instruments, we use a method with various assumptions that are based on market conditions and risks existing at each balance sheet date. For the majority of financial instruments, including most derivatives, standard market conventions and techniques such as discounted cash flow analysis, option pricing models, replacement cost and termination cost are used to determine fair value. All methods of assessing fair value result in a general approximation of value, and such value may never actually be realized. See Note 9, Derivative Instruments and Hedging Activities, for additional information regarding our derivative transactions.
     Financial Instruments
     We adopted SFAS No. 157 on January 1, 2008 for our financial assets and liabilities. SFAS No. 157 clarifies the definition of fair value, prescribes methods for measuring fair value, establishes a fair value hierarchy based on the inputs used to measure fair value and expands disclosures about the use of fair value measurements. In accordance with Financial Accounting Standards Board Staff Position No. FAS 157-2, Effective Date of FASB Statement No. 157 (FSP

157-2), we will defer the adoption of SFAS No. 157 for our nonfinancial assets and nonfinancial liabilities, except those items recognized or disclosed at fair value on an annual or more frequently recurring basis, until January 1, 2009.
     As defined in SFAS No. 157, fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. In determining fair value, we use various methods including market, income and cost approaches. Based on these approaches, we utilize certain inputs and assumptions that market participants would use in pricing the asset or liability, including assumptions about risk. These inputs can be readily observable, market corroborated, or generally unobservable inputs. We utilize valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. Based on the observability of the inputs used in the valuation techniques we are required to provide the following information according to the fair value hierarchy. The fair value hierarchy ranks the quality and reliability of the information used to determine fair values. Financial assets and liabilities carried at fair value will be classified and disclosed in one of the following three categories:
Level 1: Quoted market prices in active markets for identical assets or liabilities.
Level 2: Observable market based inputs or unobservable inputs that are corroborated by market data.
Level 3: Unobservable inputs that are not corroborated by market data.
     See Note 10, Fair Value Measurements, for further information regarding fair value measurements and our adoption of the provisions of SFAS No. 157.
     Recent Accounting Pronouncements
     SFAS No.141(R) — In December 2007, the FASB issued SFAS No. 141 (revised 2007), Business Combinations (“SFAS No. 141(R)”). In SFAS No. 141(R), the FASB retained the fundamental requirements of SFAS No. 141 to account for all business combinations using the acquisition method (formerly the purchase method) and for an acquiring entity to be identified in all business combinations. The new standard requires the acquiring entity in a business combination to recognize all (and only) the assets acquired and liabilities assumed in the transaction; establishes the acquisition-date fair value as the measurement objective for all assets acquired and liabilities assumed; requires transaction costs to be expensed as incurred; and requires the acquirer to disclose to investors and other users all of the information they need to evaluate and understand the nature and financial effect of the business combination. SFAS No. 141(R) is effective for annual periods beginning on or after December 15, 2008. Accordingly, any business combinations we engage in will be recorded and disclosed following existing GAAP until January 1, 2009. We expect SFAS No. 141(R) will have an impact on our consolidated financial statements when effective, but the nature and magnitude of the specific effects will depend upon the nature, terms and size of the acquisitions we consummate after the effective date.
     SFAS No. 159 — In February 2007, the Financial Accounting Standards Board (“FASB”) issued SFAS No. 159, The Fair Value Option for Financial Assets and Financial Liabilities (“SFAS No. 159”). SFAS No. 159 permits entities to choose, at specified election dates, to measure eligible items at fair value (“fair value option”) and to report in earnings unrealized gains and losses on those items for which the fair value option has been elected. SFAS No. 159 also requires entities to display the fair value of those financial assets and liabilities on the face of the balance sheet and establishes presentation and disclosure requirements designed to facilitate comparisons between entities that choose different measurement attributes for similar types of financial assets and liabilities. SFAS No. 159 is effective as of the beginning of an entity’s first fiscal year beginning after November 15, 2007. We have not adopted the fair value option for any financial assets or liabilities and, accordingly, the adoption of SFAS No. 159 did not have an impact on our condensed consolidated financial statements.
     SFAS No. 160 — In December 2007, the FASB issued SFAS No. 160, Noncontrolling Interests in Consolidated Financial Statements (“SFAS No. 160”). SFAS No. 160 amends Accounting Research Bulletin No. 51, Consolidated Financial Statements, and requires all entities to report noncontrolling (minority) interests in subsidiaries within equity in the consolidated financial statements, but separate from the parent shareholders’ equity. SFAS No. 160 also requires any acquisitions or dispositions of noncontrolling interests that do not result in a change of control to be accounted for as equity transactions. Further, SFAS No. 160 requires that a parent recognize a gain or loss in net income when a subsidiary is deconsolidated. SFAS No. 160 is effective for annual periods beginning on or after December 15, 2008. We are currently evaluating the impact of this pronouncement on our financial statements.

     SFAS No. 161— In March 2008, the FASB issued SFAS No. 161, Disclosures about Derivative Instruments and Hedging Activities (“SFAS No. 161”). SFAS No. 161 is intended to improve financial reporting about derivative instruments and hedging activities by requiring enhanced disclosures to enable investors to better understand their effects on an entity’s financial position, financial performance, and cash flows. It is effective for financial statements issued for fiscal years and interim periods beginning after November 15, 2008. We are currently evaluating the impact of this pronouncement on our financial statements.
     FSP No. 142-3— In April 2008, the FASB issued FSP No.142-3, Determination of the Useful Life of Intangible Assets (“FSP No. 142-3”).  FSP No. 142-3 amends the factors that should be considered in developing renewal or extension assumptions used to determine the useful life of a recognized intangible asset under SFAS No. 142, Goodwill and Other Intangible Assets (“SFAS No. 142”). The FSP is intended to improve the consistency between the useful life of an intangible asset determined under SFAS No. 142 and the period of expected cash flows used to measure the fair value of the asset under SFAS No. 141, Business Combinations (“SFAS No. 141”), and other US GAAP. FSP No. 142-3 is effective for financial statements issued for fiscal years beginning after December 15, 2008, and interim periods within those fiscal years. We are currently assessing whether the adoption of FSP No. 142-3 will have a material impact on our financial statements.
3. Strategic Transaction
     On May 7, 2008, we entered into a Transaction Agreement and Plan of Merger (the “Transaction Agreement”) with Sprint Nextel Corporation (“Sprint”) to form a new public wireless communications company (“NewCo Corporation”). Under the Transaction Agreement, we will merge with and into a wholly owned subsidiary of a newly formed LLC (“NewCo LLC”) that will consolidate into NewCo Corporation. Sprint will contribute its spectrum and certain other assets associated with its WiMAX operations (the “Sprint Assets”), preliminarily valued at approximately $7.4 billion based on the target price of $20 per share, into a separate wholly owned subsidiary of NewCo LLC. Following the merger and contribution of the Sprint Assets, Intel Corporation, (“Intel”), Google Inc., (“Google”), Comcast Corporation, (“Comcast”), Time Warner Cable Inc., (“Time Warner Cable”), and Bright House Networks, LLC, (“Bright House”) will invest a total of $3.2 billion into NewCo Corporation or NewCo LLC, as applicable. We refer to Intel, Google, Comcast, Time Warner Cable and Bright House as the “Investors.”
     In the merger, each share of our Class A Common Stock will be converted into the right to receive one share of Class A Common Stock of NewCo Corporation, which shares are entitled to one vote per share and each option and warrant to purchase shares of our Class A Common Stock will be converted into one option or warrant, as applicable, to purchase the same number of shares of the Class A Common Stock of NewCo Corporation.
     The Investors will initially receive Class A or Class B stock in NewCo Corporation and non-voting equity interests in NewCo LLC, as applicable, based upon a $20 per share purchase price, that is subject to post-closing adjustment based upon the trading prices of NewCo Corporation Class A common stock on the NASDAQ Stock Market over 15 randomly selected trading days during the 30-trading day period ending on the 90th day after the closing date. The final price per share will be based upon the volume weighted average price on such days and is subject to a cap of $23.00 per share and a floor of $17.00 per share. The aggregate number of shares and/or non-voting equity interests each Investor receives from its investment in NewCo Corporation and NewCo LLC, respectively, will be equal to its investment amount divided by such price per share. In a separate transaction to occur 90 days after closing, Trilogy Equity Partners will invest $10 million in the purchase of shares of Class A common stock on the same pricing terms as the other investors. Upon completion of the proposed transaction, Sprint will own the largest stake in the new company with approximately 51 percent equity ownership on a fully diluted basis assuming an investment price of $20.00 per share. The existing Clearwire shareholders will own approximately 27 percent and the new strategic investors, as a group, will be acquiring approximately 22 percent for their investment of $3.2 billion, both on a fully diluted basis assuming an investment price of $20.00 per share.
     In connection with our entering into the Transaction Agreement, we also expect to enter into several commercial agreements with Sprint and the Investors relating to, among other things, (i) the bundling and reselling of NewCo Corporation’s WiMAX service and Sprint’s third generation wireless services, (ii) the embedding of WiMAX chips into various devices, and (iii) the development of Internet services and protocols.
     Consummation of the Transactions are subject to various conditions, including the approval and adoption of the Transaction Agreement by our stockholders, the maintenance by Sprint and us of a minimum number of MHz-POPs coverage from our combined spectrum holdings, the effectiveness of a registration statement relating to the registration

of the Class A Common Stock of NewCo Corporation, the receipt of the consent of the Federal Communications Commission to certain of the Transactions, the expiration or termination of applicable waiting periods under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 (“HSR”) (which expired on July 11, 2008), and other customary closing conditions. The parties expect the Transaction Agreement to close during the fourth quarter of 2008.
     The Transaction Agreement contains certain termination rights for Sprint, the Investors and us. In the event the Transaction Agreement is terminated due to an adverse change in our Board’s recommendation to our stockholders to approve the Transactions in order to allow us to proceed with an alternative acquisition, as a result of our failure to close the Transactions within 12 months of the date of the Transaction Agreement if an alternative acquisition proposal is made prior to our stockholders’ meeting to vote on the Transactions and we enter into an alternative acquisition within 12 months following the termination or solely due to our material breach of a covenant in the Transaction Agreement, we would be required to pay Sprint a termination fee of $60.0 million.
     For the three and six months ended June 30, 2008, we expensed $10.2 million of costs associated with the Transaction Agreement.

     Marketable debt securities that are available for current operations are classified as short-term available-for-sale investments, and are stated at fair value. Auction rate securities without readily determinable market values are classified as long-term available-for-sale investments and are stated at fair value. Unrealized gains and losses that are deemed temporary are recorded as a separate component of accumulated other comprehensive income (loss). Realized losses are recognized when a decline in fair value is determined to be other-than-temporary, and both realized gains and losses are determined on the basis of the specific identification method.
     At June 30, 2008, we held available-for-sale short-term and long-term investments with a fair value and cost of $243.5 million. During the three and six months ended June 30, 2008, we incurred other-than-temporary impairment losses of $28.0 million and $32.8 million, respectively, related to a decline in the estimated fair values of our investment securities. There were no realized gains or losses from sales of investments during the three and six months ended June 30, 2008.
     We estimated the fair value of securities without quoted market values using internally generated pricing models that require various inputs and assumptions. In estimating fair values of these securities, we utilize certain inputs and assumptions that market participants would use in pricing the investment, including assumptions about risk. We maximize the use of observable inputs to the pricing models where available and reliable. We use certain unobservable inputs that cannot be validated by reference to a readily observable market or exchange data and rely, to a certain extent, on management’s own judgment about the assumptions that market participants would use in pricing the security. In these instances, fair value is determined by analysis of historical and forecasted cash flows, default probabilities and recovery rates, time value of money and discount rates considered appropriate given the level of risk in the security and

associated investor yield requirements. Our internally generated pricing models require us to use judgment in interpreting relevant market data, matters of uncertainty and matters that are inherently subjective in nature. The use of different judgments and assumptions could result in different fair values and security prices could change significantly based on market conditions. These internally derived values are compared to independent values received from brokers.
     Auction rate securities are variable rate debt instruments whose interest rates are normally reset approximately every 30 or 90 days through an auction process. The auction rate securities are classified as available-for-sale and are recorded at fair value. Beginning in August 2007, the auctions failed to attract buyers and sell orders could not be filled. Current market conditions are such that we are unable to estimate when the auctions will resume. When an auction fails, the security resets to a maximum rate as determined in the security documents. These rates vary from LIBOR + 84 basis points to LIBOR + 100 basis points. Refer to Note 10-Fair Value Measurements-Investment Securities for more information. While we continue to earn interest on these investments at the maximum contractual rate, until the auctions resume, the investments are not liquid. We may not have access to these funds until a future auction on these investments is successful, a secondary market develops for these securities, or the underlying collateral matures. Certain of these securities are perpetual securities with no maturity date and the others mature in 2033 and 2034. The estimated fair value of these auction rate securities no longer approximates cost and we have recorded other-than-temporary impairment losses on our auction rate securities of $27.8 million and $31.1 million for the three and six months ended June 30, 2008.
     Our investments in auction rate securities represent interests in collateralized debt obligations supported by preferred equity securities of insurance companies and financial institutions with a stated final maturity date of 2033 and 2034.  We also own auction rate securities that are asset backed capital commitment securities supported by high grade, short-term commercial paper and a put option from a monoline insurance company and these securities are perpetual and do not have a final stated maturity. These CDO securities were rated AAA/Aaa or AA/Aa by Standard & Poors and the equivalent at Moody’s rating services at the time of purchase and their ratings have not changed as of June 30, 2008. With regards to the asset backed capital commitment securities, Standard & Poors and Moody’s have downgraded these securities from AA/Aa to A1/A3, respectively, during the three months ended June 30, 2008.
     As issuers and counterparties to our investments announce financial results in the coming quarters and given current market volatility, it is possible that we may record additional other-than-temporary impairments as realized losses. We will continue to monitor our investments for substantive changes in relevant market conditions, substantive changes in the financial condition and performance of the investments’ issuers and other substantive changes in these investments that may impact their valuation.
     Current market conditions do not allow us to estimate when the auctions for our auction rate securities will resume, if ever, or if a secondary market will develop for these securities. As a result, our auction-rate securities are classified as long-term investments.
     In addition to the above mentioned securities, we hold one commercial paper security issued by a structured investment vehicle that defaulted in January 2008 and was placed into receivership. The issuer invests in residential and commercial mortgages and other structured credits including sub-prime mortgages. At June 30, 2008, the estimated fair value of this security was $4.1 million based on the pending resolution of the receivership and expected proceeds upon completion of this process. During the three and six months ended June 30, 2008, we recognized other-than-temporary impairment losses of $90,000 and $1.6 million, respectively, related to this commercial paper security. On July 23, 2008, we received from the trustee of the receivership approximately $3.8 million of the total amount expected to be received.

     Purchased Spectrum Rights and other intangibles - Spectrum licenses, which are issued on both a site-specific and a wide-area basis, authorize wireless carriers to use radio frequency spectrum to provide service to certain geographical areas in the United States and internationally. These licenses are generally acquired by us as an asset purchase or through a business combination. In some cases, we acquire licenses directly from the governmental authority in the applicable country. They are considered indefinite-lived intangible assets, except for the licenses acquired in Poland, Spain, Germany and Romania, which are considered definite-lived intangible assets due to limited license renewal history within these countries.

9. Derivative Instruments and Hedging Activities
     During the first quarter of 2008 we entered into two interest rate swap contracts with two year and three year terms. We currently have variable rate debt tied to 3-month LIBOR in excess of the $600 million notional amount of interest rate contracts outstanding and Clearwire expects this condition to persist throughout the term of the contracts. In accordance with SFAS No. 133, we designated the interest rate swap agreements as cash flow hedges. At inception, the swap agreements had a fair value of zero.
     The following table sets forth information regarding our interest rate hedge contracts as of June 30, 2008 (in thousands):
                                         
Type of   Notional           Receive   Pay   Fair market
Hedge   Amount   Maturity Date   Index Rate   Fixed rate   Value
Swap
  $ 300,000       3/5/2010     3-month LIBOR     3.50 %   $ (1,788 )
Swap
  $ 300,000       3/5/2011     3-month LIBOR     3.62 %   $ 747  
     The fair value of one of the interest rate swaps is reported as an other long-term asset, and one is reported as an other long-term liability on our condensed consolidated balance sheet at June 30, 2008. Per the guidance of SFAS No. 157, we computed the fair value of the swaps using observed LIBOR rates and market interest rate swap curves which are deemed as Level 2 inputs in the fair value hierarchy. The effective portion of changes in the fair value of the swaps are initially reported in other comprehensive income and subsequently reclassified to earnings (“interest expense”) when the hedged transactions affect earnings. Ineffectiveness resulting from the hedge is recorded in the condensed consolidated statement of operations as part of other income or expense. We also monitor the risk of counterparty default on an ongoing basis.
     As of June 30, 2008, the interest rate swaps had a fair value loss of $1.9 million, which is included in “Other Long-Term Liabilities” on our condensed consolidated balance sheet at June 30, 2008. The change in net unrealized gains/losses on cash flow hedges reported in accumulated other comprehensive income was a net $13.8 million gain and a net $671,000 loss during three and six months ended June 30, 2008, respectively. Net settlements made to counterparties under interest rate hedge contracts was $839,000 during the three and six months ended June 30, 2008.
     The change in net unrealized losses on cash flow hedges reflects reclassifications of $971,000 and $1.2 million of net unrealized losses from accumulated other comprehensive income to interest expense during the three and six months ended June 30, 2008, respectively. Amounts reported in accumulated other comprehensive income related to the interest rate swaps will be reclassified to interest expense as interest payments are made on the 3-month LIBOR variable-rate financing. We expect that the effective portion of the change in the fair value of the swaps recorded in accumulated other comprehensive income at June 30, 2008, which will be reclassified as interest expense within the next 12 months, will be approximately $5.4 million.
     We designate all derivatives as cash flow hedges. No derivatives were designated as fair value hedges or undesignated. Additionally, we did not use derivatives for trading or speculative purposes. For the three and six months ended June 30, 2008, we had no hedge ineffectiveness which required us to report other income or loss in the condensed consolidated statement of operations.

10. Fair Value Measurements
     As defined in SFAS No. 157, fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. In determining fair value, we use various methods including market, income and cost approaches. Based on these approaches, we utilize certain assumptions that market participants would use in pricing the asset or liability, including assumptions about risk. Based on the observability of the inputs used in the valuation techniques we are required to provide the following information according to the fair value hierarchy. The fair value hierarchy ranks the quality and reliability of the information used to determine fair values. Financial assets and debt instruments carried at fair value will be classified and disclosed in one of the following three categories:
Level 1: Quoted market prices in active markets for identical assets or liabilities.
Level 2: Observable market based inputs or unobservable inputs that are corroborated by market data.
Level 3: Unobservable inputs that are not corroborated by market data.
     In accordance with SFAS No. 157, it is our practice to maximize the use of observable inputs and minimize the use of unobservable inputs when developing fair value measurements. When available, we use quoted market prices to measure fair value. If listed prices or quotes are not available, fair value is based upon internally developed models that primarily use, as inputs, market-based or independently sourced market parameters, including but not limited to interest rate yield curves, volatilities, equity or debt prices, and credit curves. We utilize certain assumptions that market participants would use in pricing the financial instrument, including assumptions about risk. The degree of management judgment involved in determining the fair value of a financial instrument is dependent upon the availability of quoted market prices or observable market parameters. For financial instruments that trade actively and have quoted market prices or observable market parameters, there is minimal subjectivity involved in measuring fair value. When observable market prices and parameters are not fully available, management judgment is necessary to estimate fair value. In addition, changes in the market conditions may reduce the availability of quoted prices or observable data. In these instances, we use certain unobservable inputs that cannot be validated by reference to a readily observable market or exchange data and rely, to a certain extent, on management’s own assumptions about the assumptions that market participant would use in pricing the security. These internally derived values are compared to values received from brokers or other independent sources.
     Investment Securities
     The following table is a description of the pricing assumptions used for instruments measured at fair value, including the general classification of such instruments pursuant to the valuation hierarchy. A financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement.
         
Financial Instrument   Hierarchy   Pricing Assumptions
Investment: U.S. Treasuries
  Level 1   Market Quotes
Investment: Money Market Mutual Funds
  Level 1   Market Quotes
Debt Instrument: Credit Agreement
  Level 1   Market Quotes
Derivative: Interest Rate Swap
  Level 2   Discount of forecasted cash flows
Debt Instrument: Bell Canada Loan
  Level 2   Discount of forecasted cash flows
Investment: Commercial Paper Security
  Level 2   Discount of forecasted cash flows adjusted for default/loss probabilities and estimate of final maturity
 
       
Investment: Auction Rate Securities
  Level 3   Discount of forecasted cash flows adjusted for default/loss probabilities and estimate of final maturity
     Where quoted prices for identical securities are available in an active market, securities are classified in Level 1 of the valuation hierarchy. Level 1 securities include U.S. Treasuries and highly liquid government and corporate bonds (including commercial paper) for which there are quoted prices in active markets. In certain cases where there is limited activity or less transparency around inputs to the valuation, investment securities are classified within Level 3 of the valuation hierarchy. Fair value is based upon internally developed models that primarily use, as inputs, market-based or independently sourced market parameters, including but not limited to interest rate yield curves, volatilities, equity or

debt prices, and credit curves. We utilize certain assumptions that market participants would use in pricing the financial instrument, including assumptions about risk.
     Derivatives
     The two interest rate swap contracts entered into by us are “plain vanilla swaps” that use as their basis readily observable market parameters. Parameters are actively quoted and can be validated to external sources, including industry pricing services. These models do not contain a high level of subjectivity as the methodologies used in the models do not require significant judgment. The inputs include the contractual terms of the derivatives, including the period to maturity, payment frequency and day-count conventions, and market-based parameters such as interest rates and the credit quality of the counterparty.
     Debt Instruments
     We have two outstanding debt instruments: a $1.25 billion Credit Agreement dated as of July 3, 2007 and a loan from Bell Canada (“Bell”). Interests in the Credit Agreement are actively exchanged by investors and we use the most recent price or indication of price where an investor is willing to purchase an interest in the Credit Agreement. This liability is classified in Level 1 of the valuation hierarchy.
     The Bell loan is a private agreement and not a traded instrument. The critical terms of the loan are simple and are valued using market-standard discounted cash flow models that use as their basis readily observable market parameters. Parameters are actively quoted and can be validated to external sources. This loan is classified Level 2. On July 19, 2008 this loan reached maturity and we paid the outstanding balance. See Note 17 Subsequent Events for additional details on this transaction.
     The following table summarizes our financial assets and liabilities by level within the valuation hierarchy at June 30, 2008.

11. Commitments and Contingencies
     Our commitments for non-cancelable operating leases consist mainly of leased spectrum license fees, office space, equipment and certain of our network equipment situated on leased sites, including land, towers and rooftop locations. Certain of the leases provide for minimum lease payments, additional charges and escalation clauses. Leased spectrum agreements have initial terms of up to 30 years. Tower leases generally have initial terms of five years with multiple renewal options for additional five-year terms totaling 20 to 25 years.
     In connection with various spectrum lease agreements we have commitments to provide Clearwire services to the lessors in launched markets, and reimbursement of capital equipment and third-party service expenditures by the lessors over the term of the lease. These services to lessors for the reimbursement of capital equipment and third party service expenditures are accumulated and expensed evenly over the term of the lease, including expected renewable terms, as applicable. We expect that any remaining commitment at August 29, 2008 to not be significant and expect any remaining commitment open at August 29, 2008 will not have a material adverse impact on Clearwire. During the three and six months ended June 30, 2008, we satisfied $1.3 million and $2.5 million, respectively, related to these commitments. The maximum remaining commitment at June 30, 2008 is $93.6 million and is expected to be incurred over the term of the related lease agreements, which range from 15-30 years.
     As of June 30, 2008, we have signed purchase agreements of approximately $23.5 million to acquire new spectrum, subject to closing conditions. These transactions are expected to be completed within the next twelve months.
     Motorola Agreements — In August 2006, simultaneously with the sale of NextNet to Motorola, Clearwire and Motorola entered into commercial agreements pursuant to which we agreed to purchase certain infrastructure and supply inventory from Motorola. Under these agreements, we were committed to purchase no less than a total $150.0 million of network infrastructure equipment, modems, PC Cards and other products from Motorola on or before August 29, 2008, subject to Motorola continuing to satisfy certain performance requirements and other conditions. We are also committed to purchase certain types of network infrastructure products, modems and PC Cards exclusively from Motorola for a period of five years, which began August 29, 2006, and thereafter 51% until the term of the agreement is completed on August 29, 2014, as long as certain conditions are satisfied. For the three months ended June 30, 2008 and 2007, total purchases from Motorola under these agreements were $14.4 million and $21.7 million, respectively. For the six months ended June 30, 2008 and 2007, total purchases from Motorola under these agreements were $21.7 million and $33.7 million, respectively. For the period from the effective date of the agreement through

(continued)
June 30, 2008, total purchases from Motorola under these agreements were $120.0 million. The remaining commitment was $30.0 million at June 30, 2008. We expect that any remaining commitment at August 29, 2008 not to be significant and expect any remaining commitment open at August 29, 2008 not to have a material adverse impact on Clearwire.
     In the normal course of business, we are party to various pending judicial and administrative proceedings. While the outcome of the pending proceedings cannot be predicted with certainty, Management believes that any unrecorded liability that may result will not have a material adverse impact on our financial condition or results of operations.
12. Share-Based Payments
     On January 19, 2007, our Board of Directors adopted the 2007 Stock Compensation Plan (the “2007 Plan”), which authorizes us to grant incentive stock options, non-qualified stock options, stock appreciation rights, restricted stock, restricted stock units, and other stock awards to our employees, directors and consultants. The 2007 Plan was adopted by our stockholders on February 16, 2007. There are 15,000,000 shares of Class A common stock authorized under the 2007 Plan. Options granted under the 2007 Plan generally vest ratably over four years and expire no later than ten years after the date of grant. In February 2008, the expiration date of further options grants was changed from ten to seven years. As a result, all options granted after January 2008 will expire no later than seven years from the date of grant. Shares to be awarded under the 2007 Plan will be made available at the discretion of the Compensation Committee of the Board of Directors from authorized but unissued shares, authorized and issued shares reacquired and held as treasury shares, or a combination thereof. At June 30, 2008 there were 5,641,020 shares available for grant under the 2007 Stock Option Plan.
     Prior to the 2007 Plan, we had the following share-based arrangements: The Clearwire Corporation 2003 Stock Option Plan (the “2003 Stock Option Plan”) and The Clearwire Corporation Stock Appreciation Rights Plan (the “SAR Plan”). No additional stock options will be granted under our 2003 Stock Option Plan.
     We apply SFAS No. 123 (revised 2004), Share-Based Payment (“SFAS No. 123(R)”), to new awards and to awards modified, repurchased, or cancelled after January 1, 2006. Share-based compensation expense is based on the estimated grant-date fair value and is recognized net of a forfeiture rate on those shares expected to vest over a graded vesting schedule on a straight-line basis over the requisite service period for each separately vesting portion of the award as if the award was, in-substance, multiple awards.
     Compensation cost recognized related to our share-based awards was as follows (in thousands):

     Stock Options
     During the three and six months ended June 30, 2008, we granted 164,900 and 3,720,850 options, respectively, at a weighted average exercise price of $13.71 and $16.53, respectively. During the three and six months ended June 30, 2007, we granted 643,799 and 3,513,712 options, respectively, at a weighted average exercise price of $25.01 and $24.90, respectively. The fair value of each option granted during the three and six months ended June 30, 2008 and 2007 is estimated on the date of grant using the Black-Scholes option pricing model.
     As of June 30, 2008, a total of 18,485,411 options were outstanding at a weighted average exercise price of $14.72. We recognized $11.1 million and $10.0 million in stock-based compensation related to stock options in the three months ended June 30, 2008 and 2007, respectively. For the six months ended June 30, 2008 and 2007, we recognized $19.8 million and $17.5 million in stock-based compensation related to stock options, respectively. The total unrecognized share-based compensation costs related to non-vested stock options outstanding at June 30, 2008 was $77.9 million and is expected to be recognized over a weighted average period of approximately two years.
     We also grant options to purchase our Class A common stock to non-employee consultants who perform services. These options are adjusted to current fair value each quarter during their vesting periods as services are rendered using

the Black-Scholes option pricing model. During the three and six months ended June 30, 2008, we recognized $129,000 and $481,000, respectively, in expense related to these options. As of June 30, 2008 we have $21,000 of unamortized expense related to these options which is expected to be recognized over approximately one year. Expense for the three and six months ended June 30, 2007 was $77,000 and $181,000, respectively.
     The following variables were used in the Black-Scholes calculation:
                                 
    Three Months Ended June 30,   Six Months Ended June 30,
    2008   2007   2008   2007

Weighted average fair value per option at grant date
  $ 7.00     $ 14.92       8.48     $ 15.85  
     We grant stock options to employees of entities under common control to purchase shares of our Class A common stock. In accordance with Emerging Issues Task Force Issue No. 00-23, Issues Related to the Accounting for Stock Compensation Under APB No. 25, Accounting for Stock Issued to Employees, and FASB Interpretation No. 44, Accounting for Certain Transactions Involving Stock Compensation, and SFAS No. 123(R), the fair value of such options is recorded as a dividend. We did not grant any stock options to employees of entities under common control in the three and six months ended June 30, 2008. In the three and six months ended June 30, 2007, we recorded dividends related to such stock option grants of $0 and $1.1 million, respectively.
13. Net Loss Per Share
     Basic and diluted loss per share has been calculated in accordance with SFAS No. 128, Earnings Per Share, for the three and six months ended June 30, 2008 and 2007. As we had a net loss in each of the periods presented, basic and diluted net loss per common share are the same.
     The computations of diluted loss per share did not include the effects of the following options, shares of non-vested restricted stock, restricted stock units and warrants, as the inclusion of these securities would have been anti-dilutive (in thousands):

14.  Comprehensive Loss
     Comprehensive loss consists of two components, net loss and other comprehensive income. Other comprehensive income refers to revenue, expenses, gains and losses that under generally accepted accounting principles are recorded as a component of stockholders’ equity but are excluded from net loss. Our other comprehensive income is comprised of foreign currency translation adjustments from our subsidiaries not using the U.S. dollar as their functional currency, unrealized gains and losses on marketable securities categorized as available-for-sale and unrealized gains and losses related to our cash flow hedges.

15.  Business Segments  
     We comply with the requirements of SFAS No. 131, which establishes annual and interim reporting standards for an enterprise’s operating segments and related disclosures about its products, services, geographic areas and major customers. Operating segments are defined as components of an enterprise for which separate financial information is available that is evaluated regularly by the chief operating decision makers in deciding how to allocate resources and in assessing performance. Operating segments can be aggregated for segment reporting purposes so long as certain aggregation criteria are met. We define the chief operating decision makers as our Chief Executive Officer, Chief Operating Officer and Chief Financial Officer. As our business continues to mature, we will assess how we view and operate the business. We are organized into two reportable business segments: the United States and the International business.

     Relationships among Certain Stockholders, Directors, and Officers of Clearwire — As of June 30, 2008, ERH is the holder of approximately 65% of our outstanding Class B common stock and approximately 13% of our outstanding Class A common stock. Eagle River Inc. (“ERI”) is the manager of ERH. Each entity is controlled by Craig McCaw. Mr. McCaw and his affiliates have significant investments in other telecommunications businesses, some of which may compete with us currently or in the future. Its likely Mr. Mc Caw and his affiliates will continue to make additional investments in telecommunications businesses.
     As of June 30, 2008 and December 31, 2007 ERH held warrants entitling it to purchase 613,333 shares of our Class A common stock. The exercise price of the warrant is $15.00 per share.
     For the three and six months ended June 30, 2007, ERH earned interest relating to our senior secured notes, retired in August 2007, in the amount of $633,000 and $1.3 million, respectively. ERH received payments in the amount of $0 and $1.3 million for accrued interest during the three and six months ended June 30, 2007, respectively.
     Certain of our officers and directors provide additional services to ERH, ERI and their affiliates for which they are separately compensated by such entities. Any compensation paid to such individuals by ERH, ERI and/or their affiliates for their services is in addition to the compensation paid by us.
     Advisory Services Agreement and Other Reimbursements — Clearwire and ERI were parties to an Advisory Services Agreement, dated November 13, 2003 (the “Advisory Services Agreement”). Under the Advisory Services Agreement, ERI provided us with certain advisory and consulting services, including without limitation, advice as to the development, ownership and operation of communications services, advice concerning long-range planning and strategy for the development and growth of Clearwire, advice and support in connection with its dealings with federal, state and local regulatory authorities, advice regarding employment, retention and compensation of employees and assistance in short-term and long-term financial planning.

     Nextel Undertaking — Clearwire and Mr. McCaw entered into an agreement and undertaking in November 2003, pursuant to which we agreed to comply with the terms of a separate agreement between Mr. McCaw and Nextel Communications, Inc. (“Nextel”), so long as we were a “controlled affiliate” of Mr. McCaw as defined therein, certain terms of which were effective until October 2006. Under the agreement with Mr. McCaw, Nextel had the right to swap certain channels of owned or leased Broadband Radio Service (“BRS”) or Educational Broadband Service (“EBS”) spectrum with entities controlled by Mr. McCaw, including Clearwire. While the agreement was still effective, Nextel notified us of its request to swap certain channels, which is currently pending. There were no payments made to Nextel under this agreement through June 30, 2008.
     Intel Collaboration Agreement — On June 28, 2006, we entered into a collaboration agreement with Intel, to develop, deploy and market a co-branded mobile WiMAX service offering in the United States, that will target users of certain WiMAX enabled notebook computers, ultramobile PCs, and other mobile computing devices containing Intel microprocessors.
     Clearwire and Intel have agreed to share the revenues received from subscribers using Intel mobile computing devices on our domestic mobile WiMAX network. Intel will also receive a one time fixed payment for each new Intel mobile computing device activated on our domestic mobile WiMAX network once we have successfully achieved substantial mobile WiMAX network coverage across the United States. Through June 30, 2008, we have not been required to make any payments to Intel under this agreement. This Agreement is scheduled to be terminated upon the closing of our pending transaction with Sprint.
     Motorola Agreements — In August 2006, simultaneously with the sale of NextNet to Motorola, Clearwire and Motorola entered into commercial agreements pursuant to which we agreed to purchase certain infrastructure and supply inventory from Motorola. Refer to Note 11-Commitments and Contingencies-Motorola Agreements for more information.
     HITN and its Affiliates — In November 2003, we entered into a Master Spectrum Agreement (“MSA”) with a third-party EBS license holder, HITN. The founder and president of HITN was formerly a member of our Board of Directors. The MSA provides for terms under which HITN leases excess capacity on certain of its EBS spectrum licenses to us. The licenses covered under the MSA include all of the spectrum rights acquired in the Clearwire Spectrum Corporation acquisition, plus access to an additional twelve markets in the United States. For each market leased by HITN to us under the MSA, Clearwire and HITN entered into a separate lease agreement which contains additional lease terms. The initial lease term is 15 years with one renewal for an additional 15 years. The MSA also provides for additional shares of Class A common stock to be issued to HITN upon Clearwire reaching certain financial milestones.
     In March 2004, the MSA with HITN was amended to provide, among other things, additional leased EBS spectrum capacity in an additional major metropolitan market. Clearwire and HITN also entered into a spectrum option agreement (the “Option Agreement”) whereby we have an option to enter into leases of spectrum for which HITN has pending EBS license applications upon grant of those licenses by the FCC. The lease terms and conditions would be similar to those under the MSA.
     Subsequent to the MSA, we entered into two other related agreements with ISA and ISC. The founder and president of HITN is an owner of ISA and ISC, which are also affiliates of HITN. The agreements provided for payment to be provided to ISA and ISC in the form of warrants to purchase additional shares of Class A common stock in exchange for ISA and ISC providing opportunities for us to purchase or lease additional spectrum. Each of the agreements specifies a maximum consideration available under the agreement and, in 2005, the maximum consideration under the agreement with ISA was reached. As of December 31, 2007 the maximum consideration under the agreement with ISC was reached.
     For the three and six months ended June 30, 2007, ISC earned no revenue, and received cash of $0 and $39,000, respectively. As of June 30, 2007, $86,000 was payable to ISC in warrants to purchase 5,714 shares of Class A common stock. Cash paid to ISC for the three and six months ended June 30, 2008 was $0 and $4,000, respectively.
     Agreements with Bell Canada — In March 2005, Bell, a Canadian telecommunications company which is a subsidiary of BCE Inc. (“BCE”), purchased 8,333,333 shares of our Class A common stock for $100.0 million. At the time of the investment, Bell and BCE Nexxia, an affiliate of Bell, entered into a Master Supply Agreement (“Master

Supply Agreement”) dated March 16, 2005 with Clearwire. Under the Master Supply Agreement, Bell and BCE Nexxia provide or arrange for the provision of hardware, software, procurement services, management services and other components necessary for us to provide Voice over Internet Protocol (“VoIP”) services to their subscribers in the United States and provide day-to-day management and operation of the components and services necessary for us to provide these VoIP services. We agreed to pay to Bell or BCE Nexxia a flat fee for each new subscriber of our VoIP telephony service. We have agreed to use Bell and BCE Nexxia exclusively to provide such service unless such agreement violates the rights of third parties under its existing agreements. Total fees paid for new subscribers under the Master Supply Agreement were $203,000 and $48,000 during the three months ended June 30, 2008 and 2007, respectively. For the six months ended June 30, 2008 and 2007, total fees paid for new subscribers under the Master Supply Agreement were $203,000 and $53,200, respectively. Amounts paid for supplies, equipment and other services through Bell or BCE were $1.5 million and $920,000  for the three months ended June 30, 2008 and 2007, respectively. For the six months ended June 30, 2008 and 2007, amounts paid for supplies, equipment and other services through Bell or BCE were $3.1 million and $4.2 million, respectively. The Master Supply Agreement can be terminated for convenience on twelve months notice by either party at any time beginning on or after October 1, 2007. On October 29, 2007, we delivered a notice of termination of the Master Supply Agreement to BCE Nexxia and the agreement is expected to terminate on October 29, 2008.
     As required under the Master Supply Agreement with Bell and BCE Nexxia and in order to assist funding capital expenses and start-up costs associated with the deployment of VoIP services, BCE agreed to make available to us financing in the amount of $10.0 million. BCE funded the entire amount on June 7, 2006. The loan is secured by a security interest in the telecommunications equipment and property related to VoIP and bears interest at 7.00% per annum, and was due and paid in full on July 19, 2008. Interest expense recognized for this loan for the three months ended June 30, 2008 and 2007 was $199,000 and $186,000, respectively. Interest expense recognized for the six months ended June 30, 2008 and 2007 was $395,000 and $367,000, respectively.
     Davis Wright Tremaine LLP— The law firm of Davis Wright Tremaine LLP serves as our primary outside counsel, and handles a variety of corporate, transactional, tax and litigation matters. Mr. Wolff, our Chief Executive officer, is married to a partner at Davis Wright Tremaine. As a partner, Mr. Wolff’s spouse is entitled to share in a portion of the firm’s total profits, although she has not received any compensation directly from us. For the three months ended June 30, 2008 and 2007 we paid $1.5 million and $1.0 million, respectively, to Davis Wright Tremaine for legal services. For the six months ended June 30, 2008 and 2007 we paid $2.6 million and $2.3 million, respectively, to Davis Wright Tremaine for legal services.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations
     The following discussion and analysis summarizes the significant factors affecting our condensed consolidated results of operations, financial condition and liquidity position for the three and six months ended June 30, 2008 and 2007 and should be read in conjunction with our condensed consolidated financial statements and related notes included elsewhere in this filing. The following discussion and analysis contains forward-looking statements that reflect our plans, estimates and beliefs, including statement relating to the current Clearwire Corporation as a standalone entity that do not consider the impact of the pending combination with Sprint Nextel Corporation’s WiMAX business and the pending investment by strategic investors. Our actual results could differ materially from those discussed in the forward-looking statements. Factors that could cause or contribute to these differences include those discussed below and elsewhere in this quarterly report on Form 10-Q, particularly in the section entitled “Risk Factors.”
Forward-Looking Statements
     Statements and information included in this Quarterly Report on Form 10-Q by Clearwire Corporation (“Clearwire,” “we,” “us,” or “our”) that are not purely historical are forward-looking statements within the “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995.
     Forward-looking statements in this Quarterly Report on Form 10-Q represent our beliefs, projections and predictions about future events. These statements are necessarily subjective and involve known and unknown risks, uncertainties and other important factors that could cause our actual results, performance or achievements, or industry results, to differ materially from any future results, performance or achievement described in or implied by such statements. Actual results may differ materially from the expected results described in our forward-looking statements, including with respect to the correct measurement and identification of factors affecting our business or the extent of their likely impact, the accuracy and completeness of publicly available information relating to the factors upon which our business strategy is based, or the success of our business.
     When used in this report, the words “believe,” “expect,” “anticipate,” “intend,” “estimate,” “evaluate,” “opinion,” “may,” “could,” “future,” “potential,” “probable,” “if,” “will” and similar expressions generally identify forward-looking statements.
Pending Strategic Transaction
     On May 7, 2008, we entered into a Transaction Agreement and Plan of Merger (the “Transaction Agreement”) with Sprint Nextel Corporation (“Sprint”) to form a new public wireless communications company (“NewCo Corporation”). Under the Transaction Agreement, we will merge with and into a wholly owned subsidiary of a newly formed LLC (“NewCo LLC”). Sprint will contribute its spectrum and certain other assets associated with its WiMAX operations (the “Sprint Assets”), preliminarily valued at approximately $7.4 billion, into a separate wholly owned subsidiary of NewCo LLC. Following the merger and contribution of the Sprint Assets, Intel Corporation, (“Intel”), Google Inc., (“Google”), Comcast Corporation, (“Comcast”), Time Warner Cable Inc., (“Time Warner Cable”), and Bright House Networks, LLC, (“Bright House”) will invest a total of $3.2 billion into NewCo Corporation or NewCo LLC, as applicable. We refer to Intel, Google, Comcast, Time Warner Cable and Bright House as the “Investors.”
     In connection with our entering into the Transaction Agreement, we also expect to enter into several commercial agreements with Sprint and the Investors relating to, among other things, (i) the bundling and reselling of NewCo Corporation’s WiMAX service and Sprint’s third generation wireless services, the (ii) embedding of WiMAX chips into various devices, and (iii) the development of Internet services and protocols.
     Consummation of the transactions contemplated by the Transaction Agreement is subject to various conditions, including the approval and adoption of the Transaction Agreement by our stockholders, the maintenance by us and Sprint of a minimum number of MHz-POPs coverage from their combined spectrum holdings, the effectiveness of a registration statement relating to the registration of the Class A Common Stock of NewCo Corporation, the receipt of the consent of the Federal Communications Commission to certain of the Transactions, the expiration or termination of applicable waiting periods under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 (which expired on July 11, 2008), and other customary closing conditions. We expect the transactions to close in the fourth quarter of 2008.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS (continued)
Company Overview
     We build and operate wireless broadband networks that enable fast, simple, portable, reliable and affordable communications. Our networks cover entire communities, delivering a wireless high-speed Internet connection and enabling other services and features that create a new communications path into the home or office. We provide a portable broadband connection that delivers high speed Internet access and enables premium services, such as VoIP telephony, anytime and anywhere within our coverage area.
     Our network in our current markets relies on network infrastructure equipment that is based on non-line-of-sight, or NLOS, and Orthogonal Frequency Division Multiplexing, or OFDM, technologies, from Motorola, Inc’s Expedience line. We intend to deploy networks based on the IEEE mobile Worldwide Interoperability of Microwave Access 802.16e-2005, or mobile WiMAX, standard in all new markets. As with our current pre-WiMAX network infrastructure equipment, we expect mobile WiMAX technology to support fixed, portable and mobile service offerings using a single network architecture. In addition, as mobile WiMAX is a standards-based technology, we anticipate manufacturers will offer a number of handheld communications and consumer electronic devices that will be enabled to communicate using our mobile WiMAX network, including notebook computers, ultramobile personal computers, or UMPCs, personal data assistants, or PDAs, gaming consoles, MP3 players, and other handheld devices. We expect to launch our first mobile WiMAX markets in the second half of 2008, provided the WiMAX technologies satisfactorily pass our ongoing field trials.
     We launched our first broadband market in August 2004 and have grown rapidly in terms of the number of markets served, number of people covered by our network, and number of total subscribers. As of June 30, 2008 we offered our service for sale to an estimated 13.9 million people, or POPs, in the United States and to nearly 2.9 million POPs internationally in Ghent and Brussels, Belgium; Dublin, Ireland; and Seville, Spain.
     We ended the quarter with approximately 461,000 total subscribers worldwide, representing an increase of approximately 54% over our June 30, 2007 total subscribers of approximately 299,000 subscribers.
     As of June 30, 2008, we had approximately 410,000 customers in the United States, representing an increase of 140,000, or approximately 52%, from the approximately 270,000 U.S. subscribers we had as of June 30, 2007. Internationally, we ended the quarter with approximately 51,000 customers, representing a 22,000 increase, or approximately 76% increase from the approximately 29,000 international subscribers we had as of June 30, 2007.
     We are investing in building networks. Our efforts also include offering premium services and applications in order to make our service more attractive, such as VoIP telephony and our recently introduced PC card. This expansion will require significant capital expenditures as well as increased sales and marketing expenses, and will likely be accompanied by significant operating losses over the next five years or more as we expand the area covered by our network and invest to build our brand and develop subscriber loyalty. During 2008, we expect to launch additional markets in the United States. If introduced on the schedule we anticipate, these market launches would expand our covered population in the United States to approximately 20.0 to 22.0 million by the end of 2008.
     We believe that we have the second largest spectrum position in the 2.5 GHz (2496-2690 MHz) band in the United States with a spectrum portfolio that as of June 30, 2008 includes approximately 15.8 billion MHz-POPs, which is an industry metric that represents the amount of spectrum in a given area, measured in Megahertz, multiplied by the estimated population of that area. In Europe, as of June 30, 2008, we held approximately 8.7 billion MHz-POPs of spectrum, predominantly in the 3.5 GHz band, in Belgium, Germany, Ireland, Poland, Romania and Spain. We plan to continue acquiring spectrum in markets that we believe are attractive for our service offerings. If demand increases for spectrum rights, our cost to acquire spectrum will increase.
     We engineer our networks to optimize both the services that we offer and the number of subscribers to whom we can offer service. Consequently, we have not launched our services in a market using our current technology unless we control a minimum of six channels of spectrum that contain at least 5 MHz of spectrum each. However, we expect the spectral efficiency of technologies we deploy to continue to evolve, and as a result, we may decide to deploy our services in some markets with less spectrum. Alternatively, we could find that new technologies and subscriber usage patterns require us to have more spectrum available in our markets.

CLEARWIRE CORPORATION AND SUBSIDIARIES
MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS (continued)
     As a result of continued expansion and ongoing spectrum acquisitions, we expect to require significant additional capital, which we intend to raise through subsequent equity offerings, by increasing our debt, or a combination of the two. As of June 30, 2008, our total assets were $2.4 billion and our stockholders’ equity was $832.1 million, which compares to total assets of $2.7 billion and stockholders’ equity of $1.2 billion at December 31, 2007. Our unrestricted cash and cash equivalents and unrestricted short-term and long-term investments were $592.9 million and $1.0 billion at June 30, 2008 and December 31, 2007, respectively. As a consequence of the current turbulent financial markets, we cannot offer assurances that the necessary capital to achieve our current plan will be available on attractive terms or at all, and we plan to manage our use of capital by adjusting the rate at which we build our network, acquire spectrum and deploy our services.
     As we have concentrated our financial and management resources on expanding the geographic footprint of our network and the availability of our services, we have incurred net losses of $199.0 million and $118.1 million for the three months ended June 30, 2008 and 2007, respectively. For the six months ended June 30, 2008 and 2007 we incurred net losses of $375.4 million and $210.7 million, respectively.
     At June 30, 2008, we held available for sale short-term and long-term investments with a fair value and cost of $243.5 million, of which investments with a fair value and cost of $64.8 million were in auction rate securities. In addition, we have an investment with a fair value and recorded cost of $4.1 million in commercial paper issued by a structured investment vehicle for which an insolvency event has been declared. We recorded other-than-temporary impairment losses on this investment of $90,000 and $1.6 million, respectively, during the three and six months ended June 30, 2008. On July 23, 2008, we received from the trustee of the receivership approximately $3.8 million of the total amount expected to be received.
     Auction rate securities are variable rate debt instruments whose interest rates were historically reset approximately every 30 or 90 days through an auction process. Beginning in August 2007, the auctions failed to attract buyers and sell orders could not be filled. Current market conditions do not allow us to estimate when the auctions will resume. While we continue to earn interest on these investments at the maximum contractual rate, until the auctions resume, the investments are not liquid and we may not have access to these funds until a future auction on these investments is successful or a secondary market develops for these securities. At June 30, 2008, the estimated fair value of these auction rate securities no longer approximated cost and we recorded other-than-temporary impairment losses and realized losses on our auction rate securities of $27.8 million for the three months ended June 30, 2008. For the six months ended June 30, 2008, we recorded other-than-temporary impairment losses and realized losses on our auction rate securities of $31.1 million
Critical Accounting Policies
     Our discussion and analysis of our financial condition and results of operations are based upon our condensed consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these condensed consolidated financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate our estimates used, including those related to investments, the valuation of derivative instruments, allowance for doubtful accounts, depreciation, long-lived assets, goodwill and intangible assets, including spectrum, share-based compensation, and our deferred tax asset valuation allowance.
     Our accounting policies require management to make complex and subjective judgments. By their nature, these judgments are subject to an inherent degree of uncertainty. These judgments are based on our historical experience, terms of existing contracts, observance of trends in the industry, information provided by our customers and information available from other outside sources, as appropriate. Additionally, changes in accounting estimates are reasonably likely to occur from period to period. These factors could have a material impact on our financial statements, the presentation of our financial condition, changes in financial condition or results of operations.
     Other than a change in accounting for fair value upon the adoption of SFAS No. 157 and accounting for derivative transactions described below, there have been no other significant changes in our critical accounting estimates during the six months ended June 30, 2008 as compared to the critical accounting estimates disclosed in Management’s Discussion and Analysis of Financial Condition and Results of Operations included in our Annual Report on Form 10-K for the year ended December 31, 2007.

CLEARWIRE CORPORATION AND SUBSIDIARIES
MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS (continued)
     Fair Value Measurements
     During the first quarter of 2008, we adopted SFAS No. 157 for our financial assets and liabilities that are recognized or disclosed at fair value on an annual or more frequently recurring basis. These include our derivative instruments and our short-term and long-term investments.
     As defined in SFAS No. 157, fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. In determining fair value, we utilize certain assumptions that market participants would use in pricing the asset or liability, including assumptions about risk. These inputs can be readily observable, market corroborated, or generally unobservable inputs. We utilize valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. Based on the observability of the inputs used in the valuation techniques we are required to provide the following information according to the fair value hierarchy:
Level 1: Quoted market prices in active markets for identical assets or liabilities.
Level 2: Observable market based inputs or unobservable inputs that are corroborated by market data.
Level 3: Unobservable inputs that are not corroborated by market data.
     In accordance with SFAS No. 157 and our policy, it is our practice to maximize the use of observable inputs and minimize the use of unobservable inputs when developing fair value measurements. When available, we use quoted market prices to measure fair value. If listed prices or quotes are not available, fair value is based upon internally developed models that primarily use, as inputs, market-based or independently sourced market parameters, including but not limited to interest rate yield curves, volatilities, equity or debt prices, and credit curves. In estimating fair values, we utilize certain assumptions that market participants would use in pricing the financial instrument, including assumptions about risk. The degree of management judgment involved in determining the fair value of a financial instrument is dependent upon the availability of quoted market prices or observable market parameters. For financial instruments that trade actively and have quoted market prices or observable market parameters, there is minimal subjectivity involved in measuring fair value. When observable market prices and parameters are not fully available, management judgment is necessary to estimate fair value. In addition, changes in the market conditions may reduce the availability of quoted prices or observable data. In these instances, we use certain unobservable inputs that cannot be validated by reference to a readily observable market or exchange data and rely, to a certain extent, on management’s own judgment about the assumptions that market participant would use in pricing the security. These internally derived values are compared to values received from brokers or other independent sources.
     Derivative Instruments
     During the first quarter of 2008 we adopted SFAS No. 133 when we began hedging the LIBOR rate. SFAS No. 133, as amended and interpreted, establishes accounting and reporting standards for derivative instruments, including certain derivative instruments embedded in other contracts, and for hedging activities. As required by SFAS No. 133, we record all derivatives on the balance sheet at fair value as either assets or liabilities. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative and the resulting designation. A hedge may also remain undesignated. Derivatives used to hedge the exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivatives used to hedge the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. To qualify for hedge accounting, we must comply with the detailed rules and strict documentation requirements at the inception of the hedge, and hedge effectiveness is assessed at inception and periodically throughout the life of each hedging relationship.
     In the normal course of business, we are exposed to the effect of interest rate changes. We have limited our exposure by adopting established risk management policies and procedures including the use of derivatives. It is our policy that derivative transactions are executed only to manage exposures arising in the normal course of business and not for the purpose of creating speculative positions or trading.
     Currently, we only have derivatives that are designated as cash flow hedges and which are effective. Changes in the fair value of derivatives that are designated and effective as cash flow hedges are recorded in other comprehensive income and reclassified to the statement of operations when the effects of the item being hedged are recognized.

OPERATIONS (continued)
     All designated hedges are formally documented as to the relationship with the hedged item as well as the risk management strategy. Both at inception and on an ongoing basis, the hedging instrument is assessed as to its effectiveness. If and when a derivative is determined not to be highly effective as a hedge, or the underlying hedged transaction is no longer likely to occur, or the derivative is terminated, any changes in the derivative’s fair value, that will not be effective as an offset to the income effects of the item being hedged, will be recognized currently in the statement of operations
     To determine the fair value of derivative instruments, we use a method with various assumptions that are based on market conditions and risks existing at each balance sheet date. For the majority of financial instruments, including most derivatives, standard market conventions and techniques such as discounted cash flow analysis, option pricing models, replacement cost and termination cost are used to determine fair value. All methods of assessing fair value result in a general approximation of value, and such value may never actually be realized.

Revenue
  $ 58,563     $ 35,484     $ 23,079       65.0 %
     Revenue in the U.S. represented 82.1% and international represented 17.9% of total revenue for the three months ended June 30, 2008 compared to 81.9% and 18.1% for the three months ended June 30, 2007, respectively. This increase in U.S. revenue as a percent of total revenue is due primarily to a greater number of markets launched domestically as compared to international. As of June 30, 2008, we operated in 46 U.S. markets and four international markets covering a geographic area containing approximately 16.8 million people. This is compared to 40 U.S. and three international markets covering approximately 11.6 million people as of June 30, 2007. Total subscribers in all markets grew to approximately 461,000 as of June 30, 2008 from approximately 299,000 as of June 30, 2007. The growth in subscribers and the increase in services available to customers were the primary reasons for the increase in revenue when comparing the quarter ended June 30, 2008 to the quarter ended June 30, 2007.
     Cost of goods and services. Service costs primarily include costs associated with tower rents, direct Internet access and back haul costs, which is the transporting of data traffic between distributed sites and a central point in the market or Point of Presence (“POP”).

As a percent of revenue
    72.0 %     65.7 %                
     The increase in cost of goods and services was primarily due to an increase in the number of tower sites, increases in direct internet access and related back haul costs, as we launched more markets and incurred additional expenses as we prepared for future WiMAX builds from June 30, 2007 to June 30, 2008.
     Selling, general and administrative expense. Selling, general and administrative (“SG&A”) expense primarily includes salaries and benefits, sales commissions, travel expenses and related facilities costs for the following personnel: sales, marketing, network deployment, executive, finance and accounting, information technology, customer care, human resource and legal. It also includes costs associated with advertising, trade shows, public relations, promotions and other market development programs and third-party professional service fees.

    161.8 %     246.2 %                
     The increase in SG&A was due primarily to a $9.2 million increase in employee compensation and related costs, including facilities costs, resulting from higher employee headcount of approximately 1,820 employees at June 30, 2008 compared to approximately 1,680 employees at June 30, 2007. The primary reason these additional employees were hired was to support the launch of new markets. SG&A increases were partially offset by a decrease in marketing and advertising expenses of $4.9 million.

Depreciation and amortization
  $ 28,901     $ 19,714     $ 9,187       46.6 %
     The increase was primarily due to the additional depreciation expense associated with our continued network build-out and the depreciation of Customer Premise Equipment (“CPE”) related to associated subscriber growth. Capital expenditures for depreciable property, plant and equipment decreased to $62.3 million for the three months ended June 30, 2008, from $90.2 million for the three months ended June 30, 2007. The majority of these expenditures relate to the construction of our pre-WiMAX network, purchases of base station equipment, and CPE equipment.

Spectrum lease expense
  $ 28,522     $ 14,823     $ 13,699       92.4 %
     Total spectrum lease expense increased as a direct result of a significant increase in the number of spectrum leases held by us as well as an increase in the cost of new spectrum leases. With the significant number of spectrum leases and the increasing cost of these leases, we expect our spectrum lease expense to increase.

Interest income
  $ 3,829     $ 18,820     $ (14,991 )     (79.7 %)
     The decrease was primarily due to the reduction in interest returns earned on investments, as well as lower principal balances of short-term and long-term investments held during the second quarter of 2008 compared to 2007.

Interest expense
  $ (25,711 )   $ (23,511 )   $ (2,200 )     9.4 %
     The increase in interest expenses was primarily due to an increase in debt, as debt increased to $1.25 billion at June 30, 2008 from $655.9 million at June 30, 2007, partially offset by an overall reduction in the interest rate applied to the debt. We recorded no amortization of original issuance discount for the three months ended June 30, 2008, compared to $5.8 million for the three months ended June 30, 2007. We recorded amortization of deferred financing costs related to our $1.25 billion credit agreement of $1.7 million for the three months ended June 30, 2008, and $1.7 million for the three months ended June 30, 2007 related to our secured notes and senior term facility. In addition, we recorded $971,000 of interest expense reclassified from accumulated other comprehensive income related to our hedge activities for the three months ended June 30, 2008. These amounts were partially offset by capitalized interest of $5.6 million and $7.6 million for the three months ended June 30, 2008 and 2007, respectively.

     The increase in the other-than-temporary impairment loss and realized loss on investment securities is due to the recognition of a decline in value of investment securities, which we determined to be other than temporary. At June 30, 2008, we held available-for-sale short-term and long-term investments with a fair value and cost of $243.5 million. During the three and six months ended June 30, 2008, we incurred other-than-temporary impairment losses of $28.0 million and $32.8 million, respectively, related to a decline in the estimated fair values of our investment securities. Included in our investments were auction rate securities with a fair value and cost of $64.8 million as of June 30, 2008.

Operating Activities
     Net cash used in operating activities increased by $0.7 million to $281.4 million in the six months ended June 30, 2008, from $280.7 million in the six months ended June 30, 2007. The increase in cash used in operations is due primarily to an increase in operating expenses as we continue to expand our business. This increase in cash used was partially offset by an increase in cash received from customers, which increased to $110.9 million in the first half of 2008 from $36.1 million in the first half of 2007. This increase was primarily due to an increase in our subscriber base as we continued to both increase subscribers in our existing markets as well as operating in seven additional markets during the six months ended June 30, 2008 as compared to June 30, 2007.
Investing Activities
     During the six months ended June 30, 2008, net cash used in investing activities was $239.7 million compared to $349.6 million during the six months ended June 30, 2007, representing a $109.9 million decrease in net cash used. The decrease in net cash used in investing activities was due to a $49.2 million decrease in cash paid for property, plant and equipment and a $181.1 million decrease in cash paid for acquisitions of spectrum licenses and other. These decreases were offset by increases in sales of available for sale securities of $99.0 million and cash from restricted investments of $33.7 million.
Financing Activities
     Net cash used in financing activities was $5.5 million for the six months ended June 30, 2008 compared to $572.3 million provided by financing activities for the six months ended June 30, 2007, representing a $577.8 million decrease in cash received. This was primarily due to net cash proceeds of $556.0 million from our IPO in the first quarter of 2007. In addition, there was a contribution of $15 million in the first half of 2007 from a minority interest partner. This did not occur in the first half of 2008.
Liquidity and Capital Resource Requirements
     We believe that we currently hold sufficient cash, cash equivalents and marketable securities to cause our estimated liquidity needs to be satisfied for at least the next twelve months. We are currently focused on closing the Transaction

OPERATIONS (continued)
Agreement we entered into with Sprint and the Investors on May 7, 2008. Upon the consummation of the transactions under the Transaction Agreement, including our merger and the contribution of the Sprint Assets, the Investors will invest a total of $3.2 billion of cash proceeds into NewCo Corporation or NewCo LLC, as applicable. We expect the cash proceeds from this investment to be primarily used by NewCo Corporation and NewCo LLC to build a mobile WiMAX network in the United States and for general corporate purposes. We expect the transactions under the Transaction Agreement, which remain subject to various closing conditions, to close during the fourth quarter of 2008.
     Prior to the consummation of the transactions under the Transaction Agreement, we may seek additional financing. Any additional debt financing would increase our future financial commitments, while additional equity financing would be dilutive to our stockholders. This additional financing may not be available to us on favorable terms or at all. Our ability to obtain such additional financing depends on several factors, including market conditions, our future creditworthiness and restrictions contained in the agreement with our current lenders. If additional financing does become available, the terms of the Transaction Agreement limit the amount of additional debt we may incur and the amount and price of additional equity we may issue without the approval of Sprint and the Investors.
     We regularly evaluate our plans and strategy, and these evaluations often result in changes, some of which may be material and may significantly increase or decrease our cash requirements. If the Transaction Agreement does not close or closes later than expected or we fail to obtain additional financing, we may have to revise our current plans and strategy. Changes in our plans and strategy may include, among other things, changes to the extent and timing of our network deployment, increases or decreases in the number of our employees, introduction of new features or services, investments in capital and network infrastructure, acquisitions of spectrum or any combination of the foregoing.
Recent Accounting Pronouncements
     SFAS No.141(R) — In December 2007, the Financial Accounting Standards Board (“FASB”) issued SFAS No. 141 (revised 2007), Business Combinations (“SFAS No. 141(R)”). In SFAS No. 141(R), the FASB retained the fundamental requirements of SFAS No. 141 to account for all business combinations using the acquisition method (formerly the purchase method) and for an acquiring entity to be identified in all business combinations. The new standard requires the acquiring entity in a business combination to recognize all (and only) the assets acquired and liabilities assumed in the transaction; establishes the acquisition-date fair value as the measurement objective for all assets acquired and liabilities assumed; requires transaction costs to be expensed as incurred; and requires the acquirer to disclose to investors and other users all of the information they need to evaluate and understand the nature and financial effect of the business combination. SFAS No. 141(R) is effective for annual periods beginning on or after December 15, 2008. Accordingly, any business combinations we engage in will be recorded and disclosed following existing GAAP until January 1, 2009. We expect SFAS No. 141(R) will have an impact on our consolidated financial statements when effective, but the nature and magnitude of the specific effects will depend upon the nature, terms and size of the acquisitions we consummate after the effective date.
     SFAS No. 159 — In February 2007, the Financial Accounting Standards Board (“FASB”) issued SFAS No. 159, The Fair Value Option for Financial Assets and Financial Liabilities (“SFAS No. 159”). SFAS No. 159 permits entities to choose, at specified election dates, to measure eligible items at fair value (“fair value option”) and to report in earnings unrealized gains and losses on those items for which the fair value option has been elected. SFAS No. 159 also requires entities to display the fair value of those financial assets and liabilities on the face of the balance sheet and establishes presentation and disclosure requirements designed to facilitate comparisons between entities that choose different measurement attributes for similar types of financial assets and liabilities. SFAS No. 159 is effective as of the beginning of an entity’s first fiscal year beginning after November 15, 2007. We have not adopted the fair value option for any financial assets or liabilities and, accordingly, the adoption of SFAS No. 159 did not have an impact on our condensed consolidated financial statements.
     SFAS No. 160 — In December 2007, the FASB issued SFAS No. 160, Noncontrolling Interests in Consolidated Financial Statements (“SFAS No. 160”). SFAS No. 160 amends Accounting Research Bulletin No. 51, Consolidated Financial Statements, and requires all entities to report noncontrolling (minority) interests in subsidiaries within equity in the consolidated financial statements, but separate from the parent shareholders’ equity. SFAS No. 160 also requires any acquisitions or dispositions of noncontrolling interests that do not result in a change of control to be accounted for as equity transactions. Further, SFAS No. 160 requires that a parent recognize a gain or loss in net income when a subsidiary is deconsolidated. SFAS No. 160 is effective for annual periods beginning on or after December 15, 2008. Management is currently evaluating whether the adoption of SFAS No. 160 will have a material impact on our financial statements.

     SFAS No. 161— In March 2008, the FASB issued SFAS No. 161, Disclosures about Derivative Instruments and Hedging Activities (“SFAS No. 161”). SFAS No. 161 is intended to improve financial reporting about derivative instruments and hedging activities by requiring enhanced disclosures to enable investors to better understand their effects on an entity’s financial position, financial performance, and cash flows. It is effective for financial statements issued for fiscal years and interim periods beginning after November 15, 2008. Management is currently evaluating whether the adoption of SFAS No. 161 will have a material impact on our financial statements.
     FSP No. 142-3— In April 2008, the FASB issued Financial Accounting Standards Board Staff Position (“FSP”) No.142-3, Determination of the Useful Life of Intangible Assets (“FSP No. 142-3”). FSP No. 142-3 amends the factors that should be considered in developing renewal or extension assumptions used to determine the useful life of a recognized intangible asset under SFAS No. 142, Goodwill and Other Intangible Assets (“SFAS No. 142"). The FSP is intended to improve the consistency between the useful life of an intangible asset determined under SFAS No. 142 and the period of expected cash flows used to measure the fair value of the asset under SFAS No. 141, Business Combinations (“SFAS No. 141”), and other US generally accepted accounting principles. FSP No. 142-3 is effective for financial statements issued for fiscal years beginning after December 15, 2008, and interim periods within those fiscal years. Management is currently assessing whether the adoption of FSP No. 142-3 will have a material impact on our financial statements.
Item 3. Quantitative and Qualitative Disclosures About Market Risk
     Market risk is the potential loss arising from adverse changes in market rates and prices, such as interest rates, foreign currency exchange rates and changes in the market value of investments.
Interest Rate Risk
     Our primary interest rate risk is associated with our senior term loan facility. We have a total outstanding balance on our senior term loan facility of $1.24 billion at June 30, 2008. The rate of interest for borrowings under the senior term loan facility is the LIBOR rate plus 6.00% or the alternate base rate plus 5.00%, with interest payable quarterly with respect to alternate base rate loans, and with respect to LIBOR-based loans, interest is payable in arrears at the end of each applicable period, but at least every three months. The weighted average interest rate under this facility was 9.25% at June 30, 2008.
Interest Rate Hedge Contracts
     When interest rates rise, the fair value of our interest rate hedge contracts decrease and vice-versa, when interest rates fall, the fair value increases. As we are fixed rate payers, an increase of 100 basis points in interest rates results in a change in fair value of the interest rate swaps of $12.4 million, reducing our interest rate hedge liability from $356,000 to an interest rate hedge asset of $12.0 million. Alternatively, a decrease in interest rates of 100 basis points results in a change in fair value of $12.6 million, increasing our interest rate hedge liability to $12.9 million.
     In addition, we are exposed to certain losses in the event of non-performance by the counterparties under the interest rate hedge contracts. We expect the counterparties, which are major financial institutions with high credit ratings, to perform fully under these contracts. However, if the counterparties were to default on their obligations under the interest rate swap agreements, the agreements would terminate and we could incur higher interest expense due to the loss of protection afforded by the interest rate agreements and we could be required to pay the counterparty the fair value of the interest rate swap agreement at the time of default.
Foreign Currency Exchange Rates
     We are exposed to foreign currency exchange rate risk as it relates to our international operations. We currently do not hedge our currency exchange rate risk and, as such, we are exposed to fluctuations in the value of the U.S. dollar against other currencies. Our international subsidiaries and equity investees generally use the currency of the jurisdiction in which they reside, or local currency, as their functional currency. Assets and liabilities are translated at exchange rates in effect as of the balance sheet date and the resulting translation adjustments are recorded as a separate component of accumulated other comprehensive income (loss). Income and expense accounts are translated at the average monthly exchange rates during the reporting period. The effects of changes in exchange rates between the U.S.

CLEARWIRE CORPORATION AND SUBSIDIARIES
MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS (continued)
Dollar and the currency in which a transaction is denominated are recorded as foreign currency transaction gains (losses) as a component of net loss. This did not have a material impact on our financial statements.
Investment Risk
     At June 30, 2008, we held available-for-sale short-term and long-term investments with a fair value and cost of $243.5 million, of which investments with a fair value and cost of $64.8 million were auction rate securities and $178.7 million were government and agency issues, bonds and commercial paper. We regularly review the carrying value of our short-term and long-term investments and identify and record losses when events and circumstances indicate that declines in the fair value of such assets below our accounting basis are other-than-temporary, which we experienced with our auction rate securities during the three and six months ended June 30, 2008. The fair values of our investments are subject to significant fluctuations due to volatility of the credit markets in general, company-specific circumstances, and changes in general economic conditions.
     Beginning in August 2007, the auctions for our auction rate securities failed to attract buyers and sell orders could not be filled. Current market conditions are such that we are unable to estimate when the auctions will resume. While we continue to earn interest on these investments at the maximum contractual rate, the estimated fair value of these auction rate securities no longer approximates cost and until the auctions are successful the investments are not liquid. We may not have access to these funds until a future auction on these investments is successful, a secondary market develops for these securities, or the underlying collateral matures.
     Our investments in auction rate securities represent interests in collateralized debt obligations supported by preferred equity securities of insurance companies and financial institutions with a stated final maturity date of 2033 and 2034. We also own auction rate securities that are asset backed capital commitment securities supported by high grade, short-term commercial paper and a put option from a monoline insurance company and these securities are perpetual and do not have a final stated maturity. These CDO securities were rated AAA/Aaa or AA/Aa by Standard & Poors and the equivalent at Moody’s rating services at the time of purchase and their ratings have not changed as of June 30, 2008. With regards to the asset backed capital commitment securities, Standard & Poors and Moody’s have downgraded these securities from AA/Aa to A1/A3, respectively, during the three and six months ended June 30, 2008.
     In addition to the above mentioned securities, we hold one commercial paper security issued by a structured investment vehicle that defaulted in January 2008 and was placed into receivership. The issuer invests in residential and commercial mortgages and other structured credits including sub-prime mortgages. At June 30, 2008, the estimated fair value of this security was $4.1 million based on the pending resolution of the receivership and expected proceeds upon completion of this process. During the three and six months ended June 30, 2008, we recognized other-than-temporary impairment losses of $90,000 and $1.6 million, respectively, related to this commercial paper security. On July 23, 2008, we received from the trustee of the receivership approximately $3.8 million of the total amount expected to be received.
Derivative Instruments and Hedging Activities
     To meet our long-term investment and short-term liquidity requirements, we primarily borrow funds at variable rates plus fixed rate margins. Borrowings under our senior term loan facility bear interest at variable rates. Our interest rate risk management objective is to limit the impact of interest rate changes on the volatility of earnings and cash flows. To achieve this objective, in January of 2008 we entered into two interest rate swap contracts in order to mitigate our interest rate risk. We are not holding these derivative contracts for trading or speculative purposes.
     We currently have variable rate debt tied to 3-month LIBOR in excess of the $600 million notional amount of interest rate contracts outstanding and we expect this condition to persist throughout the term of the contracts. An increase in the 3-month LIBOR rate results in higher interest expense. We entered into the interest rate swap agreements to hedge the uncertain cash flows associated with the variable rate funding. In accordance with SFAS No. 133, we designated the interest rate swap agreements as cash flow hedges. Net settlements made to counterparties under interest rate hedge contracts was $839,000 during the three and six months ended June 30, 2008.

     In addition, we are exposed to certain losses in the event of non-performance by the counterparties under the interest rate hedge contracts. We expect the counterparties, which are major financial institutions with high credit ratings, to perform fully under these contracts. However, if the counterparties were to default on their obligations under the interest rate hedge contracts, we could be required to pay the full rates on our debt, even if such rates were in excess of the rates in the contracts.
Item 4. Controls and Procedures
     Based on their evaluation as of June 30, 2008, our Chief Executive Officer, Chief Financial Officer, and Chief Accounting Officer, have concluded that our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d- 15(e) under the Securities Exchange Act of 1934, as amended) were effective to ensure that the information required to be disclosed by us in this quarterly report on Form 10-Q was recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and regulations, and were also effective to ensure that information required to be disclosed by us in this quarterly report on Form 10-Q was accumulated and communicated to our management, including our Chief Executive Officer, Chief Financial Officer, and Chief Accounting Officer, to allow timely decisions regarding required disclosure.
     There were no changes in our internal control over financial reporting during the quarter ended June 30, 2008 that have materially affected, or are reasonably likely to materially affect our internal control over financial reporting.
     Our management, including our Chief Executive Officer, Chief Financial Officer, and Chief Accounting Officer, does not expect that our disclosure controls and procedures or our internal controls over financial reporting will prevent all errors and fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, will be detected.

PART II — OTHER INFORMATION
Item 1. Legal Proceedings
     We are a party to various pending judicial and administrative proceedings. Our management and legal counsel have reviewed the probable outcome of these proceedings, the costs and expenses reasonably expected to be incurred, the availability and limits of our insurance coverage, and our established liabilities. While the outcome of the pending proceedings cannot be predicted with certainty, based on our review, we believe that any unrecorded liability that may result will not have a material adverse effect on our liquidity, financial condition or results of operations.
Item 1A. Risk Factors
     Our business is subject to many risks and uncertainties, which may materially and adversely affect our future business, prospects, financial condition and results of operations, including the risk factors set forth in Item 1A of our Annual Report on Form 10-K for the fiscal year ended December 31, 2007 and the additional risk factors set forth below.
Failure to complete our recently announced transactions with Sprint and several strategic investors may result in material adverse consequences to our business and operations.
     On May 7, 2008, we announced that we had entered into a definitive agreement (the “Transaction Agreement”) with Sprint Nextel Corporation (“Sprint”) to combine our wireless broadband business to form a new wireless communications company. In connection with the combination, Intel Corporation, Google Inc., Comcast Corporation, Time Warner Cable Inc. and Bright House Networks (collectively, the “Investors’) have collectively agreed to invest $3.2 billion in the new company. These transactions (the “Transactions”) are subject to several closing conditions, including the approval and adoption of the Transaction Agreement by Clearwire’s stockholders, the maintenance by Clearwire and Sprint of their combined spectrum holdings, the receipt of the consent of the Federal Communications Commission (the “FCC”) to certain of the Transactions, the expiration or termination of applicable waiting periods under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 (the “HSR Act”), the non-occurrence of certain events, the consent of lenders under, or the refinancing of, our existing credit facility and other customary closing conditions. If any of these conditions are not satisfied the Transactions might not be completed. The closing conditions requiring that (i) Clearwire’s stockholders approve and adopt the Transaction Agreement, (ii) that FCC consent has been obtained and (iii) that the expiration or termination of applicable waiting periods under the HSR Act has occurred, may not be waived by the parties to the Transaction Agreement and each must be satisfied for the Transactions to be completed. In connection with the Transactions, Eagle River Holdings, LLC together with certain of its affiliates, has entered into a voting agreement with Clearwire, Sprint and the Investors pursuant to which it is required to vote the shares of Clearwire’s capital stock that it holds representing not less than 40% of the outstanding voting power of Clearwire in favor of the approval and adoption of the Transaction Agreement and the Transactions, subject to certain conditions. In addition, Intel has entered into a voting agreement with Clearwire, Sprint and the Investors pursuant to which it is required to vote its shares of Clearwire common stock in connection with the Transaction Agreement and the Transactions in the same proportion as the non-affiliated stockholders vote, if a majority of such non-affiliated stockholders vote in favor of the Transactions, subject to certain conditions.
     The parties have not yet obtained all regulatory clearances, consents and approvals required to complete the Transactions. Governmental or regulatory agencies could still seek to block or challenge the Transactions or could impose restrictions they deem necessary or desirable in the public interest as a condition to approving the Transactions. If these approvals are not received, then none of Clearwire, Sprint or the Investors will be obligated to complete the Transactions. If the approvals are received, but the applicable regulatory agency imposes any condition that would restrict a party’s freedom of action with respect to its assets or business, require a party to dispose of a material portion of its assets or pay any significant amounts in order to receive required consents or waivers, or adversely affect its rights under the Transaction Agreement, alter the Transaction Agreement, or the other agreements entered into in connection with the Transactions, or would have certain other effects, then the party subject to such conditions would not be required to complete the Transactions.
     If Clearwire’s stockholders do not approve and adopt the Transaction Agreement or if the Transactions are not completed for any other reason, Clearwire would be subject to a number of risks, including the following:
    Clearwire would not realize the anticipated benefits of the proposed Transactions, including any anticipated synergies from combining Clearwire and the Sprint WiMAX Business;

42


Table of Contents

CLEARWIRE CORPORATION AND SUBSIDIARIES
    Clearwire will be required to pay certain costs relating to the Transactions, such as legal, accounting, financial advisor and printing fees, whether or not the Transactions are completed;
 
    Clearwire may be required to pay a termination fee of $60 million if the Transaction Agreement is terminated due to an adverse change in our Board’s recommendation to our stockholders to approve the Transactions in order to allow us to proceed with an alternative acquisition, as a result of our failure to close the Transactions within 12 months of the date of the Transaction Agreement if an alternative acquisition proposal is made prior to our stockholders’ meeting to vote on the Transactions and we enter into an alternative acquisition within 12 months following the termination or solely due to our material breach of a covenant in the Transaction Agreement;
 
    the trading price of Clearwire Common Stock may decline to the extent that the current market prices reflect a market assumption that the Transactions will be completed;
 
    Clearwire would continue to be exposed to the general competitive pressures and risks discussed in our previous Annual Report on Form 10-K , which pressures and risks may be increased if the Transactions are not completed;
 
    matters relating to the Transactions (including integration planning) may require substantial commitments of time and resources by our management, which could otherwise have been devoted to other opportunities that may have been beneficial to us; and
 
    Clearwire may not be able to obtain necessary funding on acceptable terms or at all, which could significantly impact our ability to build out our network or launch new markets and may jeopardize our ability to continue to operate.
     The occurrence of any of these events individually or in combination could have a material adverse effect on the results of operations or the trading price of Clearwire Common Stock.
Our business will be subject to uncertainties and contractual restrictions while the Transactions are pending that could adversely affect its business.
     Uncertainty about the effect of the Transactions on employees and customers may have an adverse effect on our business, regardless of whether the Transactions are eventually completed. Although we have taken steps designed to reduce any adverse effects, these uncertainties may impair our ability to attract, retain and motivate key personnel until the Transactions are completed, or the Transaction Agreement is terminated, and for a period of time thereafter, and could cause customers, suppliers and others that deal with us to seek to change existing business relationships with us.
     Employee retention and recruitment may be particularly challenging during the pendency of the Transactions, as employees and prospective employees may experience uncertainty about their future roles with us. The departure of existing key employees, despite our retention and recruiting efforts, could have a material adverse impact on our business, financial condition and operating results, regardless of whether the Transactions are eventually completed.
     The pursuit of the Transactions and the preparation for the integration of Clearwire and the Sprint WiMAX business may place a significant burden on management and internal resources. There is a significant degree of difficulty and management distraction inherent in the process of closing the Transactions and integrating Clearwire’s business and the Sprint WiMAX business, which could cause an interruption of, or loss of momentum in, the activities of our existing businesses, regardless of whether the Transactions are eventually completed. Our management team will be required to devote considerable amounts of time to this integration process, which will decrease the time they will have to manage our existing business, service existing customers, attract new customers and develop new services or strategies. One potential consequence of such distractions could be the failure of management to realize other opportunities that could be beneficial to us. If our senior management is not able to effectively manage the process leading up to and immediately following the Transactions, or if any significant business activities are interrupted as a result of the integration process, our business could suffer.
     In addition, the Transaction Agreement restricts us, without the consent of Sprint and 75% in interest of the Investors (based on the amount to be invested by the Investors at the Closing), from making certain acquisitions

43

CLEARWIRE CORPORATION AND SUBSIDIARIES
and taking other specified actions until the Transactions occur or the Transaction Agreement is terminated. These restrictions may prevent us from pursuing otherwise attractive business opportunities and making other changes to their businesses before completion of the Transactions or termination of the Transaction Agreement.
The Transaction Agreement contains provisions that may discourage other companies from trying to acquire Clearwire.
     The Transaction Agreement contains provisions that may discourage a third party from submitting a business combination proposal to Clearwire that might result in greater value to Clearwire stockholders than the Transactions. The Transaction Agreement generally prohibits Clearwire from soliciting any acquisition proposals. In addition, if the Transaction Agreement is terminated by Clearwire or Sprint in circumstances that obligate Clearwire to pay a termination fee and to reimburse transaction expenses to Sprint, Clearwire’s financial condition may be adversely affected as a result of the payment of the termination fee and transaction expenses, which might deter third parties from proposing alternative business combination proposals.
