FINANCIAL STATEMENTS

      Akamai Technologies, Inc. (“Akamai” or the “Company”) provides services for accelerating and improving the delivery of content and business processes over the Internet. Akamai’s globally distributed platform comprises more than 16,000 servers in nearly 1,000 networks in 69 countries. The Company was incorporated in Delaware in 1998 and is headquartered in Cambridge, Massachusetts. Akamai currently operates in one business segment: providing global services for accelerating and improving delivery of content and business processes over the Internet.

      The accompanying condensed consolidated financial statements of Akamai have been prepared in accordance with the rules and regulations of the United States Securities and Exchange Commission (the “SEC”). The financial information included herein, other than the condensed consolidated balance sheet as of December 31, 2004, has been prepared without audit. The condensed consolidated balance sheet at December 31, 2004 has been derived from, but does not include all the disclosures contained in, the audited consolidated financial statements for the year ended December 31, 2004. In the opinion of management, these unaudited statements include all adjustments and accruals consisting only of normal recurring adjustments that are necessary for a fair presentation of the results of all interim periods reported herein. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and accompanying notes included in Akamai’s Annual Report on Form 10-K for the year ended December 31, 2004. The results of operations for the interim periods presented are not necessarily indicative of the results that may be expected for future periods.

      The accompanying condensed consolidated financial statements include the accounts of Akamai and its wholly-owned subsidiaries. Intercompany transactions and balances have been eliminated in consolidation. Certain reclassifications of prior year amounts have been made to conform to current year presentation. In connection with the preparation of the accompanying condensed consolidated financial statements, the Company concluded that it was appropriate to classify its investments in auction rate securities as short-term available-for-sale investments. Previously, such investments were classified as cash and cash equivalents. Accordingly, the Company has made revisions to the accompanying condensed consolidated statement of cash flows to reflect the gross purchases and sales of these securities as investing activities. As a result, cash used in investing activities increased by $51.1 million for the three months ended March 31, 2004. This revision in classification does not affect previously reported cash flows from operations or from financing activities for any period.

      In December 2004, the Financial Accounting Standards Board (“FASB”) issued Statement of Financial Accounting Standards(“SFAS”) No. 123R, “Share-Based Payment (revised 2004),” which is a revision of SFAS No. 123, “Accounting for Stock-Based Compensation” and supersedes Accounting Principles Board (“APB”) Opinion No. 25, “Accounting for Stock Issued to Employees.” SFAS No. 123R requires all share-based payments to employees, including grants of employee stock options, to be valued at fair value on the date of grant, and to be expensed over the applicable vesting period. Pro forma disclosure of the income statement effects of share-based payments is no longer an alternative. SFAS No. 123R is effective for the first annual period beginning after June 15, 2005. The Company expects to adopt this standard as of the beginning of fiscal year 2006 under the modified prospective transition method. Under this method, a company records compensation expense for all new awards and awards modified, repurchased, or cancelled after the required effective date. In addition, companies must also recognize compensation expense related to any awards that are not fully vested as of the effective date. Compensation expense for the unvested awards will be measured based on the fair value of the awards previously calculated in developing the pro forma disclosure in accordance with the provisions of SFAS No. 123. The Company is currently assessing the impact of adopting

FINANCIAL STATEMENTS — (Continued)

SFAS No. 123R to its consolidated results of operations but expects that the adoption will have a material impact. The pro forma information included in Note 3 reflects what the impact of applying SFAS No. 123R would have been for periods presented.

      In March 2005, the SEC issued Staff Accounting Bulletin (“SAB”) No. 107, “Share-Based Payment.” SAB No. 107 was issued to assist preparers by providing guidance regarding the application of SFAS No. 123R. SAB No. 107 describes the Staff’s views on share-based payment transactions with non-employees and covers key topics including valuation models, expected volatility and expected term. The Company will apply the principles of SAB No. 107 in conjunction with its adoption of SFAS No. 123R during the first quarter of 2006.

      Akamai accounts for stock-based awards to employees using the intrinsic value method as prescribed by APB Opinion No. 25, “Accounting for Stock Issued to Employees,” and related interpretations. Accordingly, no compensation expense is recorded for stock-based awards issued to employees and directors in fixed amounts and with fixed exercise prices at least equal to the fair market value of the Company’s common stock at the date of grant. Compensation expense is recognized on a straight-line basis over the vesting period for restricted stock grants, deferred stock units and stock options granted where the exercise price is below the market price on the date of grant. Akamai applies the provisions of SFAS No. 123 as amended by SFAS No. 148, “Accounting for Stock-Based Compensation-Transition and Disclosure, an amendment of FASB Statement No. 123, Accounting for Stock-Based Compensation,” through disclosure only for stock-based awards issued to employees and directors. All stock-based awards to non-employees are accounted for at their fair value in accordance with SFAS No. 123.

      The following table illustrates the effect on net income and net income per share if the Company had accounted for stock options issued to employees and directors under the fair value recognition provisions of SFAS No. 123, as amended by SFAS No. 148 (in thousands, except per share data):

FINANCIAL STATEMENTS — (Continued)

      The fair value of each option granted during the three months ended March 31, 2005 and 2004 is estimated on the date of grant using the Black-Scholes option pricing model with the following assumptions:

      During the three months ended March 31, 2005 and 2004, the weighted average fair value of options granted at market value on the date of grant was $8.12 and $10.92, respectively, per share.

      Basic net income per share is computed using the weighted average number of common shares outstanding during the applicable quarter. Diluted net income per share is computed using the weighted average number of common shares outstanding during the quarter, plus the dilutive effect of potential common stock. Potential common stock consists of stock options, deferred stock units, warrants, unvested restricted common stock and convertible notes.

      The following table sets forth the components used in the computation of basic and diluted net income per common share (in thousands, except per share data):

      As of March 31, 2005, the Company had issued $4.6 million in irrevocable letters of credit in favor of third-party beneficiaries, primarily related to facility leases. The letters of credit are collateralized by restricted marketable securities, of which $3.7 million are classified as long-term marketable securities and $932,000 are classified as short-term marketable securities on the condensed consolidated balance sheet dated as of March 31, 2005. The restrictions on these marketable securities lapse as the Company fulfills its obligations or as such obligations expire as provided by the letters of credit. These restrictions are expected to lapse at various times through May 2009.

FINANCIAL STATEMENTS — (Continued)

      Financial instruments that subject the Company to credit risk consist of cash and cash equivalents, marketable securities and accounts receivable. The Company maintains the majority of its cash, cash equivalents and marketable securities balances principally with domestic financial institutions that the Company believes are of high credit standing. Concentrations of credit risk with respect to accounts receivable are limited to certain customers to which the Company makes substantial sales. To reduce risk, the Company routinely assesses the financial strength of its customers and, as a consequence, believes that its accounts receivable credit risk exposure is limited. As of March 31, 2005, one customer accounted for approximately 11% of the Company’s accounts receivable balance. No other customer accounted for 10% or more of accounts receivable as of March 31, 2005 or as of December 31, 2004.

      Net accounts receivable consists of the following (in thousands):

      In January 2003, the Company adopted SFAS No. 143, “Accounting for Asset Retirement Obligations.” SFAS No. 143 addresses the accounting and reporting requirements for obligations associated with the retirement of tangible long-lived assets. As a result of adoption of this statement, the Company recorded an asset retirement obligation and associated long-lived asset of $109,000 as of January 1, 2003 for the fair value of a contractual obligation to remove leasehold improvements at the conclusion of the Company’s facility lease in Cambridge, Massachusetts. The obligation and asset are classified on the Company’s condensed consolidated balance sheet as of March 31, 2005 as non-current liabilities and property and equipment, respectively. The Company will amortize the asset and accrete the obligation over the remaining life of the associated leasehold improvements. As of March 31, 2005, the Company has approximately $120,000 recorded as the non-current asset obligation.

      Accrued expenses consist of the following (in thousands):

      As of March 31, 2005, the Company had $3.3 million of accrued restructuring liabilities. No restructuring charges were recorded during the three months ended March 31, 2005 and 2004.

      The following table summarizes the restructuring activity for the three months ended March 31, 2005 (in millions):

      All existing restructuring liabilities will be fully paid through August 2007. The amount of restructuring liabilities associated with facility leases has been estimated based on the most recent available market data and discussions with the Company’s lessors and real estate advisors as to the likelihood that the Company will be able to partially offset its obligations with sublease income. As of March 31, 2005, there was approximately $33,000 of estimated future sublease income netted in the restructuring balance.

      In June 2000, Akamai issued $300.0 million in aggregate principal amount of 5¹/2% convertible subordinated notes due July 1, 2007 for aggregate net proceeds of $290.2 million (net of initial purchaser fees and other offering expenses of $9.8 million). As of March 31, 2005, the Company had $56.6 million in aggregate principal amount of its 5¹/2% convertible subordinated notes outstanding. The 5¹/2% convertible subordinated notes are convertible at any time into the Company’s common stock at a conversion price of $115.47 per share (equivalent to 8.6603 shares of common stock per $1,000 principal amount of 5¹/2% convertible subordinated notes), subject to adjustment in certain events. In the event of a change of control, Akamai may be required to repurchase the 5¹/2% convertible subordinated notes at a repurchase price of 100% of the

principal amount together with accrued and unpaid interest. Interest on the 5¹/2% convertible subordinated notes began to accrue as of the issue date and is payable semiannually on January 1 and July 1 of each year. The 5¹/2% convertible subordinated notes are unsecured obligations and are subordinated to all existing and future senior indebtedness of Akamai. Deferred financing costs of $9.8 million, including underwriting fees and other offering expenses, for the 5¹/2% convertible subordinated notes are being amortized over the term of the notes. For the three months ended March 31, 2005 and 2004, amortization of deferred financing costs was $66,000 and $233,000, respectively.

      During the three months ended March 31, 2004, in individually negotiated transactions, the Company repurchased an aggregate of $25.0 million in principal amount of its outstanding 5¹/2% convertible subordinated notes at a repurchase price equal to 100% of the principal amount plus accrued interest. Additionally, in February 2004, the Company commenced a tender offer to repurchase up to $101.0 million in aggregate principal amount of its outstanding 5¹/2% convertible subordinated notes at a purchase price between $1,000 and $1,005 for each $1,000 of principal amount tendered. In March 2004, the Company amended the tender offer to increase the maximum price at which it was willing to repurchase the 5¹/2% convertible subordinated notes to $1,012.50 per $1,000 principal amount of the notes. Pursuant to the tender offer, in March 2004, the Company repurchased $37.9 million in aggregate principal amount of the 5¹/2% convertible subordinated notes for a total cash payment of $38.3 million. The purchase price was $1,012.50 for each $1,000 of principal amount tendered. For the three months ended March 31, 2004, the Company amortized the outstanding deferred financing costs relating the repurchased notes and the premium paid of $977,000 and $474,000, respectively, to loss on early extinguishment of debt. Additionally, the Company incurred $567,000 of advisory services and offering expenses in connection with the tender offer and repurchases, which is included in loss on early extinguishment of debt.

      In December 2003 and January 2004, Akamai issued $200.0 million in aggregate principal amount of 1% convertible senior notes due December 15, 2033 for aggregate net proceeds of $194.1 million, net of an initial purchaser’s discount and offering expenses of $5.9 million. The initial conversion price of the 1% convertible senior notes is $15.45 per share (equivalent to 64.7249 shares of common stock per $1,000 principal amount of 1% convertible senior notes). The notes may be converted into shares of the Company’s common stock at the option of the holder in the following circumstances:

      The Company may redeem the 1% convertible senior notes on or after December 15, 2010 at the Company’s option at 100% of the principal amount together with accrued and unpaid interest. Conversely, holders of the 1% convertible senior notes may require the Company to repurchase the notes at par value on

certain specified dates beginning on December 15, 2010. In the event of a change of control, the holders may require Akamai to repurchase their 1% convertible senior notes at a repurchase price of 100% of the principal amount plus accrued interest. Interest on the 1% convertible senior notes began to accrue as of the issue date and is payable semiannually on June 15 and December 15 of each year. The 1% convertible senior notes are senior unsecured obligations and are the same rank as all existing and future senior indebtedness of Akamai. The 1% convertible senior notes rank senior to all of our subordinated indebtedness, including the 5¹/2% convertible subordinated notes due 2007. Deferred financing costs of $5.9 million, including the initial purchaser’s discount and other offering expenses, for the 1% convertible senior notes are being amortized over the first seven years of the term of the notes to reflect the put and call rights discussed above. Amortization of deferred financing costs of the 1% convertible senior notes was $210,000 and $208,000 for the three months ended March 31, 2005 and 2004, respectively. Using the interest method, the Company records the amortization of deferred financing costs as interest expense in the consolidated statement of operations.

      On April 21, 2005, the Company’s Board of Directors approved amendments to the Company’s 1999 Employee Stock Purchase Plan (“1999 ESPP”). The amendments to the 1999 ESPP are as follows: the duration of the offering periods was changed from 24 months to six months; the number of times a participant may elect to change his or her percentage was changed from four times to two times; the definition of “compensation” was amended to clarify that it includes cash bonuses and other cash incentive payments; and a provision was added to clarify that upon termination of an offering period, each eligible participant will be automatically enrolled in the next offering period. The amendments will be effective as of June 1, 2005, the commencement of the next offering period under the 1999 ESPP.

      Akamai’s chief decision-maker, as defined under SFAS No. 131, “Disclosures About Segments of an Enterprise and Related Information,” is the Chief Executive Officer and the executive management team. As of March 31, 2005, Akamai operated in one business segment: providing global services for accelerating and improving the delivery of content and business processes over the Internet.

      The Company deploys its servers into networks worldwide. As of March 31, 2005, the Company had approximately $26.2 million and $4.8 million of property and equipment, net of accumulated depreciation, located in the United States and foreign locations, respectively. As of December 31, 2004, the Company had approximately $22.4 million and $2.8 million of property and equipment, net of accumulated depreciation, located in the United States and foreign locations, respectively. Akamai sells its services and licenses through a direct sales force located both domestically and abroad. For the three months ended March 31, 2005, approximately 20% of the Company’s revenues were derived from the Company’s operations outside the United States, including 16% of total revenues derived from Europe. For the three months ended March 31, 2004, approximately 19% of the Company’s revenues were derived from the Company’s operations outside the United States, including 15% of total revenues derived from Europe. No single country accounted for 10% or more of revenues derived outside the United States during these periods. For the three months ended March 31, 2005, no customer accounted for more than 10% of total revenues. For the three months ended March 31, 2004, one customer accounted for 11% of total revenues. No other customers accounted for more than 10% of revenues for any other period reported in these condensed consolidated financial statements.

      The Company’s provision for income taxes is comprised of a current and deferred portion. The current income tax provision is calculated as the estimated taxes payable or refundable on tax returns for the current

NOTES TO UNAUDITED CONDENSED CONSOLIDATED

FINANCIAL STATEMENTS — (Continued)

year. The deferred income tax provision is calculated based on changes in the estimated future tax effects attributable to temporary differences and carryforwards using expected tax rates in effect in the years during which the differences are expected to reverse.

      The Company currently has significant deferred tax assets, resulting from net operating loss carryforwards, tax credit carryforwards, and deductible temporary differences. The Company provides a full valuation allowance of approximately $361.0 million against its deferred tax assets. Management weighs the positive and negative evidence to determine if it is more likely than not that some or all of the deferred tax assets will be realized. Forming a conclusion that a valuation allowance is not needed is difficult when there is negative evidence such as cumulative losses in past years. Despite the Company’s profitability in the fiscal year ended December 31, 2004 and during the first quarter of 2005, the Company will continue to maintain a full valuation allowance on its tax benefits until profitability has been sustained over an appropriate time period and in amounts that are sufficient to support a conclusion that it is more likely than not that all or a portion of its deferred tax assets will be realized. A significant decrease in the Company’s valuation allowance would result in an immediate material income tax benefit and an increase in total assets and stockholder’s equity and could have a significant impact on the Company’s earnings in future periods.

      The Company has recorded certain tax reserves to address potential exposures involving its sales and use and franchise tax positions. These potential exposures result from the varying application of statutes, rules, regulations and interpretations by different jurisdictions. The Company’s estimate of the value of its tax reserves contains assumptions based on past experiences and judgments about the interpretation of statutes, rules and regulations by taxing jurisdictions. It is possible that the ultimate resolution of these matters may be greater or less than the amount that the Company estimated. During the three months ended March 31, 2005, based upon the resolution of its sales and use and franchise tax matters in various jurisdictions, the Company reduced such tax reserves by approximately $1.0 million.

      The Company leases its facilities and certain equipment under non-cancelable operating leases. These operating leases expire at various dates through April 2010 and generally require the payment of real estate taxes, insurance, maintenance and operating costs. The Company also leases certain equipment under capital leases, which expire at various dates through September 2005. The minimum aggregate future obligations under non-cancelable leases as of March 31, 2005 are as follows (in thousands):

      The Company has long-term purchase commitments for bandwidth usage and co-location with various network and Internet service providers. For the remainder of 2005 and for the years ended December 31, 2006 and 2007, the minimum commitments are approximately $8.4 million, $948,000 and $51,000, respectively. The Company had an equipment purchase commitment of approximately $500,000 as of March 31, 2005. This purchase commitment expires in August 2005. Additionally, as of March 31, 2005, the Company has entered into purchase orders with various vendors for aggregate purchase commitments of $7.3 million, which are expected to be paid during the remainder of 2005.

      Between July 2, 2001 and November 7, 2001, purported class action lawsuits seeking monetary damages were filed in the United States District Court for the Southern District of New York against the Company as well as against the underwriters of its October 28, 1999 initial public offering of common stock. The complaints were filed allegedly on behalf of persons who purchased the Company’s common stock during different time periods, all beginning on October 28, 1999 and ending on various dates. The complaints are similar and allege violations of the Securities Act of 1933 and the Securities Exchange Act of 1934 primarily based on the allegation that the underwriters received undisclosed compensation in connection with the Company’s initial public offering. On April 19, 2002, a single consolidated amended complaint was filed, reiterating in one pleading the allegations contained in the previously filed separate actions. The consolidated amended complaint defines the alleged class period as October 28, 1999 through December 6, 2000. A Special Litigation Committee of Akamai’s Board of Directors authorized management to negotiate a settlement of the pending claims substantially consistent with a Memorandum of Understanding that was negotiated among class plaintiffs, all issuer defendants and their insurers. The parties negotiated a settlement that is subject to approval by the Court. On February 15, 2005, the Court issued an Opinion and Order preliminarily approving the settlement, provided that the defendants and plaintiffs agree to a modification narrowing the scope of the bar order set forth in the original settlement agreement. The Company believes that it has meritorious defenses to the claims made in the complaint and, if the settlement is not finalized and approved, it intends to contest the lawsuit vigorously. An adverse resolution of the action could have a material adverse effect on the Company’s financial condition and results of operations in the period in which the lawsuit is resolved. The Company is not presently able to estimate potential losses, if any, related to this lawsuit.

      In February 2002, the Company filed suit against Speedera Networks, Inc. (“Speedera”) in federal court in Massachusetts, alleging patent infringement and false advertising by Speedera. In April 2003, the Company amended its complaint to include an allegation that Speedera infringes a newly-issued content delivery patent held by MIT and licensed to Akamai. In response, Speedera filed a counterclaim in this case alleging that Akamai has infringed a Speedera patent relating to the combined provision of traffic management and content delivery services. In June 2004, Speedera amended its counterclaim to include a second patent covering a similar service it offers. The Company believes that it has meritorious defenses to the claims made in the counterclaim.

      In June 2002, the Company filed suit against Speedera in California Superior Court alleging theft of Akamai trade secrets from an independent company that provides website performance testing services. In connection with this suit, in September 2002, the Court issued a preliminary injunction to restrain Speedera from continuing to access the Company’s confidential information from the independent company’s database and from using any data obtained from such access. In October 2002, Speedera filed a cross-claim against the Company seeking monetary damages and injunctive relief and alleging that the Company engaged in various unfair trade practices, made false and misleading statements and engaged in unfair competition. A trial date

had been set for April 18, 2005 but, as further described below, the litigation has been stayed. The Company believes that it has meritorious defenses to the claims made in Speedera’s cross-claim.

      In November 2002, the Company filed suit against Speedera in federal court in Massachusetts for infringement of a patent held by Akamai. In January 2003, Speedera filed a counterclaim in this case alleging that Akamai has infringed a patent held by Speedera. The Company believes that it has meritorious defenses to the claims made in the counterclaim.

      On March 16, 2005, the Company entered into an agreement and plan of merger providing for the acquisition of Speedera. Under the terms of the agreement, all litigation between the Company and Speedera was immediately stayed. At such time as the merger closes, all such lawsuits would be dismissed. If the acquisition of Speedera fails to be consummated, which would result in the resumption of litigation between the parties, the Company intends to contest such claims vigorously; however, there can be no assurance that the Company will be successful. The Company is not presently able to reasonably estimate potential losses, if any, related to these matters.

      In November 2002, the FASB issued Interpretation 45, or FIN 45, “Guarantor’s Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others.” FIN 45 elaborates on the existing disclosure requirements for most guarantees, including loan guarantees such as standby letters of credit. FIN 45 also clarifies that at the time an entity issues a guarantee, the entity must recognize an initial liability for the fair value, or market value, of the obligations it assumes under the guarantee and must disclose that information in its interim and annual financial statements. The disclosure provisions of FIN 45 were effective for the Company’s Annual Report on Form 10-K for the year ended December 31, 2003. The initial recognition and initial measurement provisions of FIN 45 apply on a prospective basis to guarantees issued or modified after December 31, 2002. The fair value of the Company’s guarantees issued or modified during the three months ended March 31, 2005 was determined to be immaterial.

      On March 16, 2005, the Company entered into an agreement to acquire all of the outstanding common and preferred stock, including vested and unvested stock options, of Speedera, in exchange for approximately 12 million shares of Akamai common stock, valued at approximately $130 million based on the closing price of the Akamai common stock on the NASDAQ National Market on March 15, 2005. The acquisition is expected to be accounted for by Akamai under the purchase method of accounting and is expected to close during the quarter ended June 30, 2005, subject to various regulatory approvals, approval of Speedera’s stockholders and other customary closing conditions.

      On March 16, 2005, we entered into an agreement to acquire all of the outstanding common and preferred stock, including vested and unvested stock options, of Speedera by issuing approximately 12 million shares of our common stock, valued at approximately $130 million based on the closing stock price of our common stock on the NASDAQ National Market on March 15, 2005. We expect to account for the acquisition under the purchase method of accounting. The acquisition is expected to close during the quarter ended June 30, 2005, subject to various regulatory approvals, approval of Speedera’s stockholders and other customary closing conditions. The merger agreement provides for a stay of all existing litigation between Akamai and Speedera until the closing of the merger or any earlier termination of the merger agreement. At such time as the merger closes, all lawsuits between the companies would be dismissed.

Critical Accounting Policies and Estimates

      Our management’s discussion and analysis of our financial condition and results of operations are based upon our condensed consolidated financial statements, which have been prepared by us in accordance with accounting principles generally accepted in the United States of America. 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 items, including, but not limited to, revenue recognition, accounts receivable reserves, investments, intangible assets, income and other taxes, depreciable lives of property and equipment, restructuring accruals and contingent obligations. We base our estimates and judgments on historical experience and on various other assumptions that we believe to be reasonable under the circumstances. Actual results may differ from the amounts which are derived from these estimates. See the section entitled “Application of Critical Accounting Policies and Estimates” in our Annual Report on Form 10-K for the year ended December 31, 2004 for further discussion of these critical accounting policies and estimates. There were no material changes to our critical accounting policies and estimates during the quarter ended March 31, 2005.

Results of Operations

      Revenues. Total revenues increased 24%, or $11.7 million, to $60.1 million for the three months ended March 31, 2005 as compared to $48.4 million for the three months ended March 31, 2004. The increase in total revenues for the three months ended March 31, 2005 as compared to the same period in the prior year was attributable to an increase in service revenue of $12.1 million, offset by a decrease in software and software-related revenue of $419,000. The increase in service revenue was primarily attributable to an increase in the number of customers under recurring revenue contracts, as well as an increase in traffic delivered and additional services sold to new and existing customers. As of March 31, 2005, we had 1,360 customers under recurring revenue contracts as compared to 1,172 as of March 31, 2004. These increases resulted in a higher average revenue per customer during the three months ended March 31, 2005 as compared to the same period in the prior year. The decrease in software and software-related revenues reflects a reduction in the number of customized software projects performed and a decrease in the number of software and technology licenses executed.

      For the three months ended March 31, 2005 and 2004, 20% and 19%, respectively, of our total revenues were derived from our operations located outside of the United States, including 16% and 15%, respectively, derived from Europe. No single country outside of the United States accounted for 10% or more of revenues during these periods. Resellers accounted for 25% of revenues for the three months ended March 31, 2005 as compared to 27% of revenues for the three months ended March 31, 2004. For the three months ended March 31, 2005, no customer accounted for 10% or more of total revenues. For the three months ended March 31, 2004, Microsoft Corporation accounted for 11% of total revenues. No other customer accounted for 10% or more of revenues during that period.

      Cost of Revenues. Cost of revenues includes fees paid to network providers for bandwidth and co-location of our network equipment. Cost of revenues also includes payroll and related costs and equity-related compensation for network operations personnel, cost of licenses, depreciation of network equipment used to deliver our services and amortization of internal-use software costs.

      Cost of revenues decreased 5%, or $622,000, to $11.5 million for the three months ended March 31, 2005 as compared to $12.1 million for the three months ended March 31, 2004. The decrease was primarily due to a reduction in depreciation expense of network equipment as our network assets become fully depreciated, offset by an increase in aggregate bandwidth costs. Traffic delivered over our network increased significantly in the three months ended March 31, 2005 as compared to the same period in the prior year. Despite this increase in traffic, overall bandwidth costs have continued to increase at a lower rate because we have reduced our network bandwidth costs per unit.

      Cost of revenues during the three months ended March 31, 2005 and 2004 also included credits received of approximately $456,000 and $155,000, respectively, as a result of settlements and renegotiations entered into in connection with billing disputes related to bandwidth contracts. Credits of this nature may occur in the future as a result of our efforts to monitor and reduce our network costs; however, the timing and amount of these credits, if any, will vary.

      Cost of revenues was comprised of the following (in thousands):

      We have long-term purchase commitments for bandwidth usage and co-location with various network and Internet service providers. For the remainder of 2005 and for the years ending December 31, 2006 and 2007, the current minimum commitments are approximately $8.4 million, $948,000 and $51,000, respectively.

      We expect that cost of revenues will increase during the remainder of 2005. We expect to deliver more traffic on our network, which would result in higher expenses associated with the increased traffic; however, such costs should be mitigated by lower bandwidth costs per unit. We expect increases in depreciation expense related to our network equipment and amortization of internal-use software development costs, along with payroll and related costs as we continue to make investments in our network.

      Research and Development. Research and development expenses consist primarily of payroll and related costs and equity-related compensation for research and development personnel who design, develop, test and enhance our services and our network. Research and development costs are expensed as incurred, except certain internal-use software development costs requiring capitalization. During the three months

ended March 31, 2005 and 2004, we capitalized software development costs of $2.1 million and $1.7 million, respectively, consisting of external consulting and payroll and payroll-related costs related to the development of internal-use software used to deliver our services and operate our network. These capitalized internal-use software costs are amortized to costs of revenues over their estimated useful lives of two years.

      Research and development expenses increased 35%, or $935,000, to $3.6 million for the three months ended March 31, 2005 as compared to $2.7 million for the three months ended March 31, 2004. The increase in research and development expenses was primarily due to an increase in payroll and related costs due to an increase in headcount, offset by a slight increase in capitalization of internal-use software development costs. The following table quantifies the net increase in research and development expenses for the three months ended March 31, 2005 as compared to the three months ended March 31, 2004 (in millions):

      We believe that research and development expenses will continue to increase for the remainder of 2005, as we continue to increase hiring of development personnel and make investments in our core technology service and refinements to our other service offerings.

      Sales and Marketing. Sales and marketing expenses consist primarily of payroll and related costs, equity-related compensation and commissions for personnel engaged in marketing, sales and service support functions, as well as advertising and promotional expenses.

      Sales and marketing expenses increased 20%, or $2.7 million, to $16.7 million for the three months ended March 31, 2005 as compared to $14.0 million for the three months ended March 31, 2004. The increase in sales and marketing expenses was primarily due to a rise in payroll and related costs, particularly commissions, due to revenue growth. Additionally, during the first quarter of 2005, marketing costs increased due to higher advertising and promotional costs. The following table quantifies the net increase in sales and marketing expenses for the three months ended March 31, 2005 as compared to the three months ended March 31, 2004 (in millions):

      We believe that sales and marketing expenses will continue to increase during the remainder of 2005 due to an expected increase in commissions on higher forecasted sales, an increase in hiring of sales personnel and additional expected increases in marketing costs.

      General and Administrative. General and administrative expenses consist primarily of the following components:

      During the three months ended March 31, 2005 and 2004, we capitalized software development costs of approximately $50,000 and $75,000, respectively, consisting of external consulting costs and payroll and payroll-related costs related to the development of internally-used software applications.

      General and administrative expenses increased 6%, or $642,000, to $11.8 million for the three months ended March 31, 2005 as compared to $11.2 million for the three months ended March 31, 2004. The increase in general and administrative expenses was primarily due to an increase in payroll and related costs as a result of headcount growth, as well as an increase in legal, consulting and advisory services, particularly related to litigation costs associated with trials that had been scheduled to occur in 2005. These increases were offset by a reduction in depreciation expense as a result of assets becoming fully depreciated. The following table quantifies the net reduction in general and administrative expenses for the three months ended March 31, 2005 as compared to the three months ended March 31, 2004 (in millions):

      We expect general and administrative expenses to remain relatively constant on a quarterly basis during the remainder of 2005. If our proposed acquisition of Speedera is not completed, however, our litigation costs would increase which would cause our overall general and administrative expenses to increase compared to those of 2004.

      Amortization of Other Intangible Assets. Amortization of other intangible assets consists of amortization of assets acquired in business combinations and amortization of acquired license rights. Amortization of other intangible assets remained constant at $12,000 for the each of the three months ended March 31, 2005 and 2004. We expect to amortize approximately $36,000 of other intangible assets related to acquired license rights for the remainder of 2005 and $48,000 in each year thereafter through 2008, at which time such assets will have been fully amortized.

      Interest Income. Interest income includes interest earned on invested cash balances and marketable securities. Interest income remained constant at $598,000 for each of the three months ended March 31, 2005 and 2004. Interest income remained constant during each of these periods because our invested cash and marketable securities balance levels were relatively constant.

      Interest Expense. Interest expense includes interest paid on our debt obligations as well as amortization of deferred financing costs. Interest expense decreased 57%, or $2.1 million, to $1.6 million for the three months ended March 31, 2005 as compared to $3.8 million for the three months ended March 31, 2004. The decrease was due to our repurchases of a substantial portion of our outstanding 5¹/2% convertible subordinated notes at various times throughout 2004, partially offset by interest payable on our 1% convertible senior notes issued in December 2003 and January 2004. We believe that interest expense on our debt obligations, including deferred financing amortization and capital lease interest expense, will not exceed $6.5 million in 2005.

      Other Expense, net. Other net expense represents net foreign exchange losses incurred during the periods presented. Other net expense increased 426%, or $588,000, to $726,000 for the three months ended March 31, 2005 as compared to $138,000 for the three months ended March 31, 2004. The increase was due

to exchange rate fluctuations. Net other (expense) income may fluctuate in the future based upon movements in foreign exchange rates.

      Loss on Early Extinguishment of Debt. During the three months ended March 31, 2004, we recorded a loss on early extinguishment of debt of $2.0 million as a result of costs incurred in connection with our repurchase of a total of $62.9 million in principal amount of our 5¹/2% convertible subordinated notes during the period. This loss of $2.0 million consists of the reduction of $977,000 of deferred financing costs associated with repurchases of notes prior to their maturity, $567,000 in advisory services costs incurred related to the repurchases and $474,000 in premiums above par value paid to repurchase such notes. No debt repurchases were made during the three months ended March 31, 2005.

      Provision for Income Taxes. Provision for income taxes increased $445,000, or 530%, to $529,000 for the three months ended March 31, 2005 as compared to $84,000 for the three months ended March 31, 2004. Provision for income taxes for these periods relates to foreign income taxes that may fluctuate in the future based upon changes in foreign income. Additionally, the provision for income taxes during the three months ended March 31, 2005 includes alternative minimum tax expense. Despite our profitability in 2004 and for the first quarter of 2005, as of March 31, 2005, we will continue to maintain a full valuation allowance on our tax benefits until profitability has been sustained over an appropriate time period and in amounts that are sufficient to support a conclusion that it is more likely than not that a portion or all of the deferred tax assets will be realized. A decrease in our valuation allowance would result in an immediate material income tax benefit.

Liquidity and Capital Resources

      To date, we have financed our operations primarily through the following transactions:

      As of March 31, 2005, cash, cash equivalents and marketable securities totaled $118.0 million, of which $4.6 million is subject to restrictions limiting our ability to withdraw or otherwise use such cash, cash equivalents and marketable securities. See “Letters of Credit” below.

      Cash provided by operating activities was $18.7 million for the three months ended March 31, 2005 compared to $8.6 million for the three months ended March 31, 2004. The increase in cash provided by operating activities was primarily due to increased service revenue of $12.1 million during the first quarter of 2005, as well as an increase of net cash provided by accounts payable and accrued expenses of $7.1 million. We expect that cash provided by operating activities will continue to remain positive as a result of an upward trend in cash collections related to higher revenue billings, partially offset by an expected increase in operating expenses that require cash outlays due to expected increases in headcount. However, the timing and amount of future working capital changes and our ability to manage our days sales outstanding will affect the future amount of cash used in or provided by operating activities.

      Cash used in investing activities was $15.1 million for the three months ended March 31, 2005 compared to cash provided by investing activities of $52.3 million for the three months ended March 31, 2004. Cash used in investing activities for the three months ended March 31, 2005 reflects net purchases, sales and maturities of investments of $5.3 million and capital expenditures of $9.7 million, consisting of the capitalization of internal-use software development costs related to our current and future service offerings and purchase of network infrastructure equipment. Cash provided by investing activities for the three months ended March 31,

2004 was primarily from the net sale and maturity of marketable securities of $50.3 million, offset by capital expenditures of $3.0 million. For the three months ended March 31, 2004, cash provided by investing activities also included a decrease of $5.0 million in restricted cash to reflect our repurchase of $5.0 million in principal amount of our 5¹/2% convertible subordinated notes in early 2004. We expect that total capital expenditures, a component of cash used in investing activities, will be approximately 10 to 15% of revenues in 2005.

      Cash provided by financing activities was $1.5 million for the three months ended March 31, 2005, as compared to cash used in financing activities of $36.5 million for the three months ended March 31, 2004. Cash provided by financing activities during the three months ended March 31, 2005 reflects $1.6 million in proceeds received from the issuance of common stock to employees upon exercise of stock options offset by payments on capital lease obligations of $134,000. Cash used in financing activities for the three months ended March 31, 2004 reflects proceeds received from the issuance of our 1% convertible senior notes, net of financings costs, of $24.3 million and proceeds from issuances of common stock to employees upon exercise of stock options of $2.2 million. Such proceeds were offset by payments made to repurchase $62.9 million in principal amount of our 5¹/2% convertible subordinated notes and payments on our capital lease obligations of $131,000.

      Changes in cash, cash equivalents and marketable securities are dependent upon changes in working capital items such as deferred revenues, accounts payable, accounts receivable and various accrued expenses, as well as changes in our capital and financial structure due to debt repurchases and issuances, stock option exercises, sales of equity instruments and similar events.

      The following table represents the net inflows and outflows of cash, cash equivalents and marketable securities for the periods presented (in millions):

      We believe, based on our present business plan, that our current cash, cash equivalents and marketable securities of $118.0 million and forecasted cash flows from operations will be sufficient to meet our cash needs for working capital and capital expenditures for at least the next 24 months. If the assumptions underlying our business plan regarding future revenue and expenses change or if unexpected opportunities or needs arise, we may seek to raise additional cash by selling equity or debt securities. We may seek to retire or refinance our long-term debt with cash, equity or a combination thereof. If additional funds are raised through the issuance of equity or debt securities, these securities could have rights, preferences and privileges senior to those accruing to holders of common stock, and the terms of such debt could impose restrictions on our operations. The sale of additional equity or convertible debt securities could result in additional dilution to our stockholders. See “Factors Affecting Future Operating Results.”

Contractual Obligations and Commercial Commitments

      The following table presents our contractual obligations and commercial commitments as of March 31, 2005 over the next five years and thereafter (in millions):

Letters of Credit

      As of March 31, 2005, we had issued $4.6 million in irrevocable letters of credit in favor of third-party beneficiaries, primarily related to facility leases. The letters of credit are collateralized by restricted marketable securities, of which $3.7 million are classified as long-term marketable securities and $932,000 are classified as short-term marketable securities on the condensed consolidated balance sheet dated as of March 31, 2005. The restrictions on these marketable securities lapse as we fulfill our obligations or as such obligations expire as provided by the letters of credit. These restrictions are expected to lapse through May 2009.

Off-Balance Sheet Arrangements

      We have entered into indemnification agreements with third parties, including vendors, customers, landlords, our officers and directors, shareholders of acquired companies, joint venture partners and third parties to whom we license technology. Generally, these indemnification agreements require us to reimburse losses suffered by the third party due to various events, such as lawsuits arising from patent or copyright infringement or our negligence. These indemnification obligations are considered off-balance sheet arrangements in accordance with Financial Accounting Standards Board, or FASB, Interpretation 45, or FIN 45, “Guarantor’s Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others.” See “Guarantees” in the footnotes to our consolidated financial statements included in the Annual Report on Form 10-K for the year ended December 31, 2004 for further discussion of these indemnification agreements. The fair value of guarantees issued or modified during the three months ended March 31, 2005 was determined to be immaterial. As of March 31, 2005, we do not have any additional off-balance sheet arrangements, except for operating leases, and have not entered into transactions with special purpose entities.

Recent Accounting Pronouncements

      In December 2004, the FASB issued SFAS No. 123R, which is a revision of SFAS No. 123, “Accounting for Stock-Based Compensation” and supersedes APB Opinion No. 25, “Accounting for Stock Issued to Employees.” SFAS No. 123R requires all share-based payments to employees, including grants of employee stock options, to be valued at fair value on the date of grant, and to be expensed over the applicable vesting period. Pro forma disclosure of the income statement effects of share-based payments is no longer an alternative. SFAS No. 123R is effective for the first annual period beginning after June 15, 2005. We expect to adopt this standard as of the beginning of fiscal year 2006 under the modified prospective transition method.

Under this method, a company records compensation expense for all new awards and awards modified, repurchased, or cancelled after the required effective date. In addition, companies must also recognize compensation expense related to any awards that are not fully vested as of the effective date. Compensation expense for the unvested awards will be measured based on the fair value of the awards previously calculated in developing the pro forma disclosure in accordance with the provisions of SFAS No. 123. We are currently assessing the impact of adopting SFAS No. 123R to our consolidated results of operations but expect that the adoption will have a material impact. The pro forma information included in Note 3 of our consolidated financial statements included in this quarterly report on Form 10-Q reflects what the impact of applying SFAS No. 123R would have been for periods presented.

      In March 2005, the Securities and Exchange Commission, or SEC, issued Staff Accounting Bulletin, or SAB, No. 107, “Share-Based Payment.” SAB No. 107 was issued to assist preparers by providing guidance regarding the application of SFAS No. 123R. SAB No. 107 describes the Staff’s views on share-based payment transactions with non-employees and covers key topics including valuation models, expected volatility and expected term. We will apply the principles of SAB No. 107 in conjunction with our adoption of SFAS No. 123R during the first quarter of 2006.

Factors Affecting Future Operating Results

      We compete in markets that are new, intensely competitive, highly fragmented and rapidly changing. We have experienced and expect to continue to experience increased competition. Many of our current competitors, as well as a number of our potential competitors, have longer operating histories, greater name recognition, broader customer relationships and industry alliances and substantially greater financial, technical and marketing resources than we do. Other competitors may attract customers by offering services that may be perceived as less sophisticated versions of our services at lower prices than those we charge. Our competitors may be able to respond more quickly than we can to new or emerging technologies and changes in customer requirements. Some of our current or potential competitors may bundle their services with other services, software or hardware in a manner that may discourage website owners from purchasing any service we offer or Internet service providers from installing our servers. In addition, potential customers may decide to purchase or develop their own hardware, software and other technology solutions rather than rely on an external provider like Akamai. Increased competition could result in price and revenue reductions, loss of customers and loss of market share, which could materially and adversely affect our business, financial condition and results of operations.

      Prices we have been charging for some of our services have declined in recent years. We expect that this decline may continue in the future as a result of, among other things, existing and new competition in the markets we serve. Consequently, our historical revenue rates may not be indicative of future revenues based on comparable traffic volumes. If we are unable to sell our services at acceptable prices relative to our costs or if we are unsuccessful with our strategy of additional services and features to our existing EdgeSuite delivery customers, our revenues and gross margins will decrease, and our business and financial results will suffer.

      The year ended December 31, 2004 was the first fiscal year during which we achieved profitability as measured in accordance with accounting principles generally accepted in the United States of America. We have large fixed expenses, and we expect to continue to incur significant bandwidth, sales and marketing, product development, administrative, interest and other expenses. Therefore, we will need to generate higher

revenues to maintain profitability. There are numerous factors that could, alone or in combination with other factors, impede our ability to increase revenues and/or moderate expenses, including:

      The market for our services is characterized by rapidly changing technology, evolving industry standards and new product and service introductions. Our operating results depend on our ability to develop and introduce new services into existing and emerging markets. The process of developing new technology is complex and uncertain, and if we fail to accurately predict customers’ changing needs and emerging technological trends, our business could be harmed. We must commit significant resources to developing new services or enhancements to our existing services before knowing whether our investments will result in services the market will accept. In addition, in an effort to control expenses, our spending on research and development decreased over the past three years. Furthermore, we may not execute successfully our technology initiatives because of errors in planning or timing, technical hurdles that we fail to overcome in a timely fashion, or a lack of appropriate resources. Failures in execution or market acceptance of new services we introduce could result in competitors providing those solutions before we do and loss of market share, revenues and earnings.

      We have long-term debt. As of March 31, 2005, our total long-term debt was approximately $256.6 million, of which $56.6 million is due on June 30, 2007, and our stockholders’ deficit was approximately $110.5 million. Our level of indebtedness could adversely affect our future operations by increasing our vulnerability to adverse changes in general economic and industry conditions and by limiting or prohibiting our ability to obtain additional financing for future capital expenditures, acquisitions and general corporate and other purposes. In addition, if we are unable to make interest or principal payments when due, we would be in default under the terms of our loans, which would result in all principal and interest becoming due and payable which, in turn, would seriously harm our business.

      Our business is dependent on providing our customers with fast, efficient and reliable distribution of application and content delivery services over the Internet. For our core services, we currently provide a standard guarantee that our networks will deliver Internet content 24 hours a day, seven days a week, 365 days a year. If we do not meet this standard, our customer does not pay for all or a part of its services on that day. Our network or services could be disrupted by numerous events, including natural disasters, failure or refusal of our third-party network providers to provide the necessary capacity, power losses, and intentional disruptions of our services, such as disruptions caused by software viruses or attacks by unauthorized users. For example, approximately four percent of our customers experienced a brief delay in delivery of services on June 15, 2004 as a result of a denial of service resulting from an attack by hackers on our network. We believe this attack targeted several well-known websites that are customers of Akamai. Although we have taken steps to enhance our ability to prevent the occurrence of such an incident, there can be no assurance that attacks by unauthorized users will not be attempted in the future, that our enhanced security measures will be effective or that a successful attack would not be damaging. Any widespread loss or interruption of our network or services would reduce our revenues and could harm our business, financial results and reputation.

      Our operations are dependent in part upon transmission capacity provided by third-party telecommunications network providers. We believe that we have access to adequate capacity to provide our services; however, there can be no assurance that we are adequately prepared for unexpected increases in bandwidth demands by our customers. In addition, the bandwidth we have contracted to purchase may become unavailable for a variety of reasons. For example, a number of these network providers are operating under the protection of the federal bankruptcy laws. As a result, there is uncertainty about whether such providers, or others that enter into bankruptcy, will be able to continue to provide services to us. Any failure of these network providers to provide the capacity we require, due to financial or other reasons, may result in a reduction in, or interruption of, service to our customers. If we do not have access to third-party transmission capacity, we could lose customers. If we are unable to obtain transmission capacity on terms commercially acceptable to us or at all, our business and financial results could suffer. In addition, our telecommunications and network providers typically provide rack space for our servers. Damage or destruction of, or other denial of access to, a facility where our servers are housed could result in a reduction in, or interruption of, service to our customers.

      Our services are highly complex and are designed to be deployed in and across numerous large and complex networks. From time to time, we have needed to correct errors and defects in our software. In the future, there may be additional errors and defects in our software that may adversely affect our services. We may not have in place adequate quality assurance procedures to ensure that we detect errors in our software in a timely manner. If we are unable to efficiently fix errors or other problems that may be identified, or if there are unidentified errors that allow persons to improperly access our services, we could experience loss of revenues and market share, damage to our reputation, increased expenses and legal actions by our customers.

      On March 16, 2005, we entered into an agreement and plan of merger providing for our acquisition of Speedera in exchange for the issuance of approximately 12 million shares of our common stock. Completion of the merger is subject to regulatory approval, as well as the approval of Speedera’s stockholders and other customary closing conditions. The process of obtaining such approval could be expensive and time-consuming. If we are unable to obtain, or are significantly delayed in obtaining, such approvals or are otherwise unable to complete the merger, we would have devoted substantial resources and management attention without any

accompanying benefit. In such an event, our financial condition and results of operations could be materially adversely affected.

      We have made acquisitions of other companies in the past and may enter into business combinations and acquisitions in addition to the proposed Speedera acquisition in the future. Acquisitions are typically accompanied by a number of risks, including the difficulty of integrating the operations and personnel of the acquired companies, the potential disruption of our ongoing business, the potential distraction of management, expenses related to the acquisition and potential unknown liabilities associated with acquired businesses. We face all of these risks in connection with the proposed Speedera acquisition. If we are not successful in completing acquisitions that we may pursue in the future, we may be required to reevaluate our business strategy, and we may incur substantial expenses and devote significant management time and resources without a productive result. In addition, with future acquisitions, we could use substantial portions of our available cash or, as in the proposed Speedera merger transaction, make dilutive issuances of securities. Future acquisitions or attempted acquisitions could also have an adverse effect on our ability to remain profitable.

      Our financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of these financial statements requires us to make estimates and judgments about, among other things, taxes, revenue recognition, capitalization of internal-use software, contingent obligations, doubtful accounts and restructuring charges, among other things. These estimates and judgments affect the reported amounts of our assets, liabilities, revenues and expenses, the amounts of charges accrued by us, such as those made in connection with our restructuring charges, and related disclosure of contingent assets and liabilities. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances. If our estimates or the assumptions underlying them are not correct, we may need to accrue additional charges that could adversely affect our results of operations, which in turn could adversely affect our stock price.

      We have licensed technology from MIT covered by various patents, patent applications and copyrights relating to Internet content delivery technology. Some of our core technology is based in part on the technology covered by these patents, patent applications and copyrights. Our license is effective for the life of the patents and patent applications; however, under limited circumstances, such as a cessation of our operations due to our insolvency or our material breach of the terms of the license agreement, MIT has the right to terminate our license. A termination of our license agreement with MIT could have a material adverse effect on our business.

      Other companies or individuals, including our competitors, may obtain patents or other proprietary rights that would prevent, limit or interfere with our ability to make, use or sell our services. Companies providing Internet-related products and services are increasingly bringing suits alleging infringement of their proprietary rights, particularly patent rights. We have been named as a defendant in several lawsuits alleging that we have violated other companies’ intellectual property rights. Any litigation or claims, whether or not valid, could result in substantial costs and diversion of resources and require us to do one or more of the following:

      If we are forced to take any of these actions, our business may be seriously harmed. If we are found to infringe the proprietary rights of others. In the event of a successful claim of infringement against us and our failure or inability to obtain a license to the infringed technology, our business and operating results could be materially adversely affected.

      We rely on a combination of patent, copyright, trademark and trade secret laws and restrictions on disclosure to protect our intellectual property rights. We have brought numerous lawsuits against entities that we believe are infringing on our intellectual property rights. These legal protections afford only limited protection. Monitoring unauthorized use of our services is difficult and we cannot be certain that the steps we have taken will prevent unauthorized use of our technology, particularly in foreign countries where the laws may not protect our proprietary rights as fully as in the United States. Although we have licensed from other parties proprietary technology covered by patents, we cannot be certain that any such patents will not be challenged, invalidated or circumvented. Furthermore, we cannot be certain that any pending or future patent applications will be granted, that any future patent will not be challenged, invalidated or circumvented, or that rights granted under any patent that may be issued will provide competitive advantages to us.

      Our future success depends upon the continued services of our executive officers and other key technology, sales, marketing and support personnel who have critical industry experience and relationships that they rely on in implementing our business plan. None of our officers or key employees is bound by an employment agreement for any specific term. We have a “key person” life insurance policy covering only the life of F. Thomson Leighton, our Chief Scientist and a member of our Board of Directors. The loss of the services of any of our key employees could delay the development and introduction of and negatively impact our ability to sell our services.

      We have operations in several foreign countries and may continue to expand our sales and support organizations internationally. Such expansion could require us to make significant expenditures. We are increasingly subject to a number of risks associated with international business activities that may increase our costs, lengthen our sales cycle and require significant management attention. These risks include:

      If our revenues decrease or grow more slowly than we anticipate or if our operating expenses increase more than we expect or cannot be reduced in the event of lower revenues, we may need to obtain funding from outside sources. If we are unable to obtain this funding, our business would be materially and adversely affected. In addition, even if we were to find outside funding sources, we might be required to issue securities with greater rights than the securities we have outstanding today. We might also be required to take other actions that could lessen the value of our common stock, including borrowing money on terms that are not favorable to us, if at all.

      Laws and regulations that apply to communications and commerce over the Internet are becoming more prevalent. In particular, the growth and development of the market for online commerce has prompted calls for more stringent tax, consumer protection and privacy laws, both in the United States and abroad, that may impose additional burdens on companies conducting business online. This could negatively affect the businesses of our customers and reduce their demand for our services. Tax laws that might apply to our servers, which are located in many different jurisdictions, could require us to pay additional taxes that would adversely affect our continued profitability. Internet-related laws, however, remain largely unsettled, even in areas where there has been some legislative action. The adoption or modification of laws or regulations relating to the Internet or our operations, or interpretations of existing law, could adversely affect our business.

      Provisions of our amended and restated certificate of incorporation, amended and restated by-laws and Delaware law could make it more difficult for a third party to acquire us, even if doing so would be beneficial to our stockholders. In addition, our Board of Directors has adopted a shareholder rights plan the provisions of which could make it more difficult for a potential acquirer of Akamai to consummate an acquisition transaction without the approval of our Board of Directors.

      We are named as a defendant in a purported class action lawsuit filed in 2001 alleging that the underwriters of our initial public offering received undisclosed compensation in connection with our initial public offering of common stock in violation of the Securities Act and the Securities Exchange Act of 1934, as amended, which we refer to as the Exchange Act. Any conclusion of these matters in a manner adverse to us could have a material adverse affect on our financial position and results of operations.

      In the ordinary course of business, we may become involved in litigation, administrative proceedings and governmental proceedings. Such matters can be time-consuming, divert management’s attention and resources and cause us to incur significant expenses. Furthermore, there can be no assurance that the results of any of these actions will not have a material adverse effect on our business, results of operations or financial condition.

      Our exposure to market risk for changes in interest rates relates primarily to our debt and investment portfolio. In our investment portfolio we do not use derivative financial instruments. We place our investments with high quality issuers and, by policy, limit the amount of risk by investing primarily in money market funds, United States Treasury obligations, high-quality corporate obligations and certificates of deposit.

      We may incur realized losses as a result of early redemptions of our debt securities. Our 5¹/2% convertible subordinated notes and 1% convertible senior notes are subject to changes in market value. Under certain conditions, the holders of our 1% convertible senior notes may require us to redeem the notes on or after December 15, 2010. As of March 31, 2005, the carrying amount and fair value of the 5¹/2% convertible subordinated notes were $56.6 million and $57.6 million, respectively. As of March 31, 2005, the carrying amount and fair value of the 1% convertible senior notes were $200.0 million and $200.5 million, respectively.

      We have operations in Europe and Asia. As a result, we are exposed to fluctuations in foreign exchange rates. Additionally, we may continue to expand our operations globally and sell to customers in foreign locations, which may increase our exposure to foreign exchange fluctuations.

      Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we evaluated the effectiveness of our disclosure controls and procedures as of March 31, 2005. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives, and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as of March 31, 2005, our Chief Executive Officer and Chief Financial Officer concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.

      No changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) occurred during the fiscal quarter ended March 31, 2005 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
