NETWORK APPLIANCE, INC.
NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(Dollar and share amounts in thousands, except per-share data)
(Unaudited)

1.	The Company	
      Based in Sunnyvale, California, Network Appliance was incorporated in California in April 1992, and reincorporated in Delaware in November 2001. Network Appliance offers unified storage solutions for the data-intensive enterprise. NetApp® network storage solutions and service offerings provide data-intensive enterprises with consolidated storage, improved data center operations, economical business continuance, and efficient remote data access across the distributed enterprise.

2.	Condensed Consolidated Financial Statements	
      The accompanying interim unaudited condensed consolidated financial statements have been prepared by Network Appliance, Inc. without audit and reflect all adjustments, (consisting only of normal recurring adjustments) which are, in the opinion of management, necessary for a fair presentation of our financial position, results of operations and cash flows for the interim periods presented. The statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“generally accepted accounting principles”) for interim financial information and in accordance with the instructions to Form 10-Q and Article 10-01 of Regulation S-X. Accordingly, they do not include all information and footnotes required by generally accepted accounting principles for annual consolidated financial statements.

      We operate on a 52-week or 53-week year ending on the last Friday in April. For presentation purposes we have indicated in the accompanying interim unaudited condensed consolidated financial statements that our fiscal year end is April 30. The first six months of fiscal 2005 and 2004 were 26-week and 27-week fiscal periods, respectively.

      These financial statements should be read in conjunction with the audited consolidated financial statements and accompanying notes included in our Annual Report on Form 10-K for the year ended April 30, 2004. The results of operations for the three and six-month periods ended October 29, 2004 are not necessarily indicative of the operating results to be expected for the full fiscal year or future operating periods. In the following notes to our interim condensed consolidated financial statements, Network Appliance Inc. is also referred to as “we”, “our” and “us”.

3.	Use of Estimates	
      The preparation of the condensed consolidated financial statements in conformity with accounting principles generally accepted in the United States of America 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 condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Such estimates include, but are not limited to, revenue recognition and allowances; valuation of goodwill and intangibles; accounting for income taxes; inventory reserves and write-down; restructuring accruals; impairment losses on investments; accounting for stock-based compensation; and loss contingencies. Actual results could differ from those estimates.

4.	Stock Compensation	
      We account for stock-based compensation in accordance with the provisions of Accounting Principle Board Opinion (“APB”) No. 25,  “Accounting for Stock Issued to Employees,”  and comply with the disclosure provisions of SFAS No. 123 as amended by SFAS No. 148,  “Accounting for Stock-Based Compensation — Transition and Disclosures.”  Deferred compensation recognized under APB No. 25 is amortized ratably to expense over the vesting periods. We account for stock options issued to non-employees in accordance with

the provisions of SFAS No. 123 and Emerging Issues Task Force (“EITF”) Issue No. 96-18 “Accounting for Equity Instruments That Are Issued to Other Than Employees for Acquiring, or in Conjunction with Selling, Goods or Services”  under the fair value based method.

      Had compensation expense been determined based on the fair value at the grant date for awards, consistent with the provisions of SFAS No. 123, our pro forma net income and pro forma net income per share would be as follows (in thousands, except per share data):

Diluted net income per share, pro forma	 	$	0.09	 	 	$	0.07	 	 	$	0.17	 	 	$	0.05	 	

	 	 	 	

	 	 	 	

	 	 	 	

	 	
      We amortize deferred stock-based compensation ratably over the vesting periods of the applicable stock purchase rights, restricted stocks and stock options, generally four years. Deferred stock compensation under APB No. 25 and pro forma net income under the provisions of SFAS No. 123 are adjusted to reflect cancellations and forfeitures due to employee terminations as they occur.

      We recorded $1,968 and $3,995 of deferred compensation expense for the three and six-month periods ended October 29, 2004, respectively, and $502 and $1,021 for the three and six-month periods ended October 31, 2003, respectively, primarily related to the amortization of deferred stock compensation from unvested options assumed in the WebManage and Spinnaker acquisitions, the retention escrow shares relative to Spinnaker, the grant of stock options to certain highly compensated employees below fair value at the date of grant and the award of restricted stock to certain employees. The net increase in deferred compensation expense reflected primarily higher stock compensation relating to the Spinnaker acquisition and restricted stock awards offset by forfeitures of unvested options assumed in the Spinnaker and WebManage acquisitions.

      Estimated future deferred stock compensation amortization as of October 29, 2004, for the remainder of fiscal 2005, and fiscal years 2006, 2007 and 2008 are expected to be $3,540, $6,637, $5,098 and $3,705, respectively, and none thereafter.

      We recorded $171 and $248 in compensation expense in the three and six-month periods ending October 29, 2004 and $391 and $526 in the three and six-month periods ending October 31, 2003, respectively, for the fair value of options granted to a member of the Board of Directors in recognition for services performed outside of the normal capacity of a board member.

6.	Goodwill and Intangible Assets	
      Goodwill is reviewed annually for impairment (or more frequently if indicators of impairment arise). We completed our annual impairment assessment on February 27, 2004 and concluded that goodwill was not impaired. From the period subsequent to February 27, 2004 through October 29, 2004, there was no impairment of goodwill and intangible assets.

7.	Derivative Instruments	
      As a result of our significant international operations, we are subject to risks associated with fluctuating exchange rates. We use derivative financial instruments, principally currency forward contracts and currency options, to attempt to minimize the impact of exchange rate movements on our balance sheet relating to certain foreign currency assets and liabilities and operating results. We have established transaction and balance sheet risk management programs to protect against reductions in fair value and volatility of future cash flows caused by changes in exchange rates. Factors that could have an impact on the effectiveness of our hedging program include the accuracy of forecasts and the volatility of foreign currency markets. These programs reduce, but do not always entirely eliminate, the impact of currency exchange movements. The maturities of these instruments are generally less than one year. Currently, we do not enter into any foreign exchange forward contracts to hedge exposures related to firm commitments or equity investments. Our major foreign currency exchange exposures and related hedging programs are described below:
 	 	
 	      Balance Sheet Exposures. We utilize currency forward contracts and currency options to hedge currency exchange rate fluctuations related to certain foreign currency assets and liabilities. Gains and losses on these derivatives offset gains and losses on the assets and liabilities being hedged and the net amount is included in earnings. For the three and six-month periods ended October 29, 2004, net gains generated by hedged assets and liabilities totaled $2,983 and $4,273, respectively, and were offset by losses on the related derivative instruments of $2,992 and $5,208, respectively. For the three and six-month periods ended October 31, 2003, net gains generated by hedged assets and liabilities totaled $2,298 and $4,745, respectively, and were offset by losses on the related derivative instruments of $3,458 and $6,076, respectively.	
 	 	
 	      The premiums paid on the foreign currency option contracts are recognized as a reduction to Total Other Income, Net, when the contract is entered into. Other than the risk associated with the financial condition of the counterparties, our maximum exposure related to foreign currency options is limited to the premiums paid.	
 	 	
 	      Forecasted Transactions. We use currency forward contracts to hedge exposures related to forecasted sales and operating expenses denominated in Euros and British Pounds. These contracts are designated as cash flow hedges when the transactions are forecasted and in general closely match the underlying forecasted transactions in duration. The contracts are carried on the balance sheet at fair value and the effectiveness is measured on a quarterly basis with the effective portion of the contracts’ gains and losses recorded as other comprehensive income until the forecasted transaction occur. No ineffectiveness was recognized in earnings during the three and six-month periods ended October 29, 2004 and October 31, 2003.	
      We do not believe that these derivatives present significant credit risks, because the counterparties to the derivatives consist of major financial institutions, and we manage the notional amount of contracts entered into with any one counterparty. We do not enter into derivative financial instruments for speculative or trading purposes.

8.	Earnings Per Share	
      Basic net income per share is computed by dividing income available to common stockholders by the weighted average number of common shares outstanding for that period. Diluted net income per share is computed giving effect to all dilutive potential shares that were outstanding during the period. Dilutive potential common shares consist of incremental common shares subject to repurchase, common shares issuable upon exercise of stock options and restricted stock awards.

      During all periods presented, we had certain options outstanding, which could potentially dilute basic earnings per share in the future, but were excluded in the computation of diluted earnings per share in such

periods, as their effect would have been antidilutive. These certain options were antidilutive in the three and six-month periods ended October 29, 2004 and October 31, 2003 as these options’ exercise prices were above the average market prices in such periods. For the three-month periods ended October 29, 2004 and October 31, 2003, 19,589 and 16,234 shares of common stock options with a weighted average exercise price of $46.14 and $53.66, respectively, were excluded from the diluted net income per share computation. For the six-month periods ended October 29, 2004 and October 31, 2003, 23,443 and 23,998 shares of common stock options with a weighted average exercise price of $42.26 and $43.16, respectively, were excluded from the diluted net income per share computation.

9.	Stockholders’ Equity	

 	Stock Repurchase Program	
      On May 13, 2003, we announced that the Board of Directors approved a $150,000 stock repurchase program to purchase shares of our outstanding common stock in the open market. On May 18, 2004, we announced that the Board authorized an expansion of the program to purchase an additional $200,000 of outstanding common stock. Total authorized stock purchase spending may be up to $350,000. The repurchases were recorded as treasury stock and resulted in a reduction of stockholders’ equity. The stock repurchase program may be suspended or discontinued at any time. The duration of the repurchase program is open-ended. Under the program, we may purchase shares of common stock through open market transactions at prices deemed appropriate by management. The timing and amount of repurchase transactions under this program will depend on market conditions and corporate and regulatory considerations. The purchases will be funded from available working capital.

      During fiscal 2004, we repurchased 6,853 shares of our common stock at an average price of $19.87 per share for an aggregate cost of $136,171. During the first half of fiscal 2005, we purchased 4,048 shares of our

common stock at an average price of $20.51 per share for an aggregate purchase price of $83,014. As of October 29, 2004, we had purchased 10,901 shares of our common stock at an average price of $20.11 per share for an aggregate purchase price of $219,185 since the inception of the stock repurchase program

10.	Restructuring Charges	
      In fiscal 2002, as a result of continuing unfavorable economic conditions and a reduction in IT spending rates, we implemented two restructuring plans, which included reductions in workforce and consolidations of facilities.

 	Fiscal 2002 Second Quarter Restructuring Plan	
      As a result of the restructuring in August 2001, we recorded a charge of $7,980. The restructuring charge included $4,796 of severance-related amounts, $2,656 of committed excess facilities and facility closure expenses, and $528 in fixed assets write-offs. The reserve balance related to this restructuring charge of $280 at October 29, 2004 was included in other accrued liabilities.

      In the event that the foreign facilities are not subleased, we will be obligated for additional total lease payments of approximately $305 as of October 29, 2004 to be payable through January 2006.

      During the second quarter of fiscal 2005, we paid $544 pursuant to final resolution of certain severance-related restructuring accruals. As of October 29, 2004, we have $178 outstanding in our accrued and unpaid severance-related restructuring costs due to changes in estimated costs of certain severance-related matters. We expect to pay or adjust the remaining severance-related restructuring costs pending the outcome of the ultimate resolution of these matters in the next twelve months.

 	Fiscal 2002 Fourth Quarter Restructuring Plan	
      In April 2002, we completed a restructuring related to the closure of an engineering facility and consolidation of resources to the Sunnyvale headquarters. As a result of this restructuring, we incurred a charge of $5,850. The restructuring charge included $813 of severance-related amounts, $4,564 of committed excess facilities and facility closure expenses, and $473 in fixed assets write-offs. Of the reserve balance at October 29, 2004, $612 was included in other accrued liabilities and the remaining $4,224 was classified as long-term obligations.

      In fiscal 2003 and 2004, we updated our assumptions and estimates based on certain triggering events, which resulted in additional net charges of $923 and $1,327 respectively, primarily relating to sublease assumptions for our engineering facility lease. Our restructuring estimates are reviewed and revised periodically and may result in a substantial charge to restructuring expense should different conditions prevail than were anticipated in previous management estimates. Such estimates included various assumptions such as the time period over which the facilities will be vacant, expected sublease terms, and expected sublease rates. In the event that the engineering facility is not subleased as anticipated, we will be obligated for additional total lease payments of $1,761 as of October 29, 2004 to be payable through November 2010.

11.	Short-Term Investments	
      All our investments are classified as available for sale at October 29, 2004 and April 30, 2004. Available-for-sale investments with original maturities of greater than three months are classified as short-term investments, as these investments generally consist of highly marketable securities that are intended to be available to meet current cash requirements. Investment securities classified as available-for-sale are reported at fair market value, and net unrealized gains or losses are recorded in accumulated other comprehensive loss, a separate component of stockholders’ equity, net of taxes. Any gains or losses on sales of investments are computed based upon specific identification. For all periods presented, realized gains and losses on available-for-sale investments were not material. Management evaluates investments on a regular basis to determine if an other-than-temporary impairment has occurred. Our investments in publicly held companies are generally considered impaired when a decline in the fair value of an investment as measured by quoted market prices is less than its carrying value and such a decline is not considered temporary.

12.	New Accounting Pronouncements	
      The Financial Accounting Standards Board (“FASB”) issued Interpretation 46 (“FIN 46”), “Consolidation of Variable Interest Entities, ” in January 2003, and a revised interpretation of FIN 46 (“FIN 46-R”) in December 2003. FIN 46 requires certain variable interest entities (“VIEs”) to be consolidated by the primary beneficiary of the entity if the equity investors in the entity do not have the characteristics of a controlling financial interest or do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support from other parties. The provisions of FIN 46 are effective immediately for all arrangements entered into after January 31, 2003. Since January 31, 2003, the Company has not invested in any entities it believes are variable interest entities for which the Company is the primary beneficiary. For all arrangements entered into after January 31, 2003, the Company is required to continue to apply FIN 46 through April 30, 2004. The Company is required to adopt the provisions of FIN 46-R for those arrangements on May 1, 2004. For arrangements entered into prior to February 1, 2003, the Company was required to adopt

13

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

the provisions of FIN 46-R on May 1, 2004. The adoption of FIN 46-R did not have an impact on the financial position, results of operations or cash flows of the Company.

      In November 2003, the EITF reached an interim consensus on EITF No. 03-01, “The Meaning of Other-Than-Temporary Impairment and its Application to Certain Investments,”  to require additional disclosure requirements for securities classified as available-for-sale or held-to-maturity for fiscal years ending after December 15, 2003. In March 2004, the EITF reached a final consensus on this Issue, to provide additional guidance which companies must follow in determining whether investment securities have an impairment which should be considered other-than-temporary. The guidance is applicable for reporting periods after June 15, 2004. Adoption of the consensus did not have a significant impact on the carrying value of its investments at October 29, 2004. The Company will continue to monitor the carrying value of its investments under this new guidance. On September 30, 2004, the FASB issued FSP (FASB Staff Position) EITF Issue 03-1-a to delay the effective date for the measurement and recognition guidance contained in EITF 03-01 until further guidance is issued.

(1) 	We lease sales offices and research and development facilities throughout the U.S. and internationally. These sales offices are also leased under operating leases which expire through fiscal 2019. We are responsible for certain maintenance costs, taxes, and insurance under these leases. Substantially all lease agreements have fixed payment terms based on the passage of time. Some lease agreements provide us with the option to renew the lease. Our future operating lease obligations would change if we were to exercise these renewal options and if we were to enter into additional operating lease agreements. Certain real estate operating sub-lease income of $233 has been included as a reduction of the payment amounts shown in the table. Rent operating lease payments in the table exclude the leases impacted by the restructurings and include only rent lease commitments that are over one year.	
 	 	
(2) 	Venture capital funding commitments includes a quarterly committed management fee based on a percentage of our committed funding to be payable through June 2011.

(3) 	Purchase commitments and other represent agreements to purchase component inventory from our suppliers and/or contract manufacturers that are enforceable and legally binding against us in the short and long-term. Other commitments include examples such as facilities-related and utilities usage minimum cash commitment we expect to pay in the long-term. Purchase commitments and other excludes purchases of good and services we expect to consume in the ordinary course of business in the next twelve months. It also excludes costs that are not reasonably estimable at this time.	
 	 	
(4) 	Under certain communications contracts with major telephone companies as well as maintenance contracts with multiple vendors, we are required to pay based on a minimum volume. Such obligations expire in January 2009.	
 	 	
(5) 	As a result of headcount reductions and a restructuring in fiscal 2002, we are not currently utilizing certain existing space at our California headquarters site. Additionally, we have also exited office space under non-cancellable leases in certain locations both in the U.S. and Europe. If we are unable to successfully sublease our vacated and unoccupied office space under operating leases, we would be obligated to pay $2,066 in excess of the liability recorded in our restructuring reserves. See “Note 10 — Restructuring Charges.”	
 	 	
(6) 	The amounts outstanding under these letters of credit relate to workers’ compensation, customs guarantee and a foreign lease.	
 	 	
(7) 	Restricted cash arrangements relate to facility lease requirements, service performance guarantees, customs and duties guarantees, and VAT requirements and are included under Prepaid Expenses and Other and Other Assets on our Consolidated Balance Sheets.	
      In May 2000, we entered into a split dollar insurance arrangement with Daniel J. Warmenhoven. Under the arrangement, we will pay the annual premiums on several insurance policies on the life of the survivor of Mr. Warmenhoven and his wife Charmaine Warmenhoven, and Mr. Warmenhoven will pay us each year for a portion of those premiums equal to the economic value of the term insurance coverage provided him under the policies. For each of the 2001, 2002, 2003, 2004 and 2005 fiscal years, we paid an aggregate net annual premium on these split dollar polices in the amount of approximately $2,050. Under the arrangement, we will be reimbursed for all premium payments made on those policies, and it is intended that we will be reimbursed not later than May 2005. Accordingly, such balances have been reclassified from Other assets to Prepaid expenses and other at October 29, 2004. The policies are owned by a family trust established by Mr. Warmenhoven, and upon the death of the survivor of Mr. Warmenhoven and his wife or any earlier cash-out of the policies, we will be entitled to a portion of the insurance proceeds or cash surrender value of the policies equal to the net amount of cumulative premiums paid on those policies by us, and the balance will be paid to the trust. We have obtained a collateral assignment of the policies as a security interest for our portion of the proceeds or cash surrender value payable to us under the policies, and neither Mr. Warmenhoven nor the trust may borrow against the policies while that security interest remains in effect. The arrangement is terminable by us upon thirty (30)-days prior notice, and such termination will trigger a refund of the net cumulative premiums paid by us on the policies.

      From time to time, we have committed to purchase various key components used in the manufacture of our products. We establish accruals for estimated losses on purchased components for which we believe it is probable that they will not be utilized in future operations. To the extent that such forecasts are not achieved, our commitments and associated accruals may change.

      We are subject to various legal proceedings and claims which may arise in the normal course of business. While the outcome of these legal matters is currently not determinable, we do not believe that any current litigation or claims will have a material adverse effect on our business, cash flow, operating results, or financial condition.

14.	Guarantees	
      As of October 29, 2004, our financial guarantees consisted of standby letters of credit outstanding, bank guarantee, and restricted cash, which were related to facility lease requirements, service performance guarantees, customs and duties guarantees, VAT requirements, and workers’ compensation plans. The maximum amount of potential future payments under these arrangements was $4,921 and $4,338 as of October 29, 2004 and April 30, 2004, respectively. Of this maximum exposure, $3,101 and $2,736 of restricted cash was classified under Prepaid expenses and Other Assets on our balance sheet at October 29, 2004 and April 30, 2004, respectively. Except for the restricted cash recorded on our balance sheet, we have not recorded any liability at October 29, 2004 for the remaining $1,820 guarantees.

      As of October 29, 2004, our notional fair values of foreign exchange forward and foreign currency option contracts totaled $194,604. We do not believe that these derivatives present significant credit risks, because the counterparties to the derivatives consist of major financial institutions, and we manage the notional amount of contracts entered into with any one counterparty. We do not enter into derivative financial instruments for speculative or trading purposes. Other than the risk associated with the financial condition of the counterparties, our maximum exposure related to foreign currency forward and option contracts is limited to the premiums paid.

      We offer both recourse and non-recourse lease financing arrangements to our customers. Under the terms of recourse leases, which are generally three years or less, we remain liable for the aggregate unpaid remaining lease payments to the third-party leasing company in the event that any customers were to default. We defer 100% of the recourse lease obligation and recognize revenue over the term of the lease as the lease payments become due. As of October 29, 2004 and April 30, 2004, the maximum recourse exposure under such leases totaled approximately $5,875 and $6,755, respectively. Under the terms of the non-recourse leases we do not have any continuing obligations or liabilities. To date, we have not experienced significant losses under this lease financing program.

      We do not maintain a general warranty reserve for estimated costs of product warranties at the time revenue is recognized due to our extensive product quality program and processes and because our global customer service inventories utilized to correct product failures are carried at zero cost.

      We enter into standard indemnification agreements in the ordinary course of business. Pursuant to these agreements, we agree to defend and indemnify the other party, primarily our customers or business partners or subcontractors for damages and reasonable costs incurred in any suit or claim brought against them alleging that our products sold to them infringe any U.S. patent, copyright, trade secret or similar right. If a product becomes the subject of an infringement claim, we may, at our option: (i) replace the product with another non-infringing product that provides substantially similar performance; (ii) modify the infringing product so that it no longer infringes but remains functionally equivalent; (iii) obtain the right for the customer to continue using the product at our expense and for the reseller to continue selling the product; (iv) take back the infringing product and refund to customer the purchase price paid less depreciation amortized on a straight line basis. We have not been required to make material payments pursuant to these provisions historically. We have not identified any losses that are probable under these provisions and, accordingly, we have not recorded a liability related to these indemnification provisions.

Overview

      Based in Sunnyvale, California, Network Appliance was incorporated in California in April 1992, and reincorporated in Delaware in November 2001. Network Appliance offers unified storage solutions for the data-intensive enterprise. Network Appliance TM  network storage solutions and service offerings provide data-intensive enterprises with consolidated storage, improved data center operations, economical business continuance, and efficient remote data access across the distributed enterprise. Network Appliance solutions are the data management and storage foundation for enterprises, government agencies, and universities worldwide.

 	Second Quarter Fiscal 2005 Highlights	
      Throughout the second quarter of fiscal year 2005, we introduced new security and compliance solutions, expanded partnerships, and continued to grow iSCSI deployments. A wide range of enterprise customers have chosen to deploy NetApp for a variety of reasons — reduced complexity, a low total cost of ownership (TCO), advanced management capabilities through Data ONTAP TM  software and a range of advanced storage and software management capabilities.

      The key drivers of growth included demand for data protection solutions, growth in our Windows® business and the continued migration from direct attached storage to network storage. Our storage-attached networks (“SAN”) penetration continued to grow with the majority of fibre channel SAN systems deployed in combination with either network-attached storage (“NAS”) or iSCSI protocols. We believe that the trend towards unification of storage continues to accelerate, as exemplified by the strong performance of our SAN and iSCSI business.

      Customers across all geographies deploy our solutions for a variety of database, security, and other data center and mission-critical applications. We expect to continue to see strong demand for storage in many areas, including mission-critical tier-one environments, distributed enterprise, disk-to-disk backup, compliance, disaster recovery, and unified SAN and NAS solutions. We recently announced NetApp’s next generation software platform, Data ONTAP 7G, providing flexible data management for enterprise grid storage environments. With Data ONTAP 7G, we also expanded the capabilities of our gFiler TM storage systems by adding fibre channel SAN capabilities, and providing a virtualized storage solution for multi-vendor/protocol storage environments. We plan to continue to leverage our product capabilities to enhance our storage grid architectures.

      Overall, our year-over-year revenue growth was primarily driven by strong demand for our new products across all major product lines, increased sales of our software and services products, additional channel/partner opportunities, and improving IT spending. We believe the data storage market experienced growth and increased IT spending but remain cautiously optimistic about the economic recovery. While we are focused on increasing revenue and gaining market share, some of our competition may be challenged to

Table of Contents
sustain their market share. However, we believe that those competitors who survived the economic downturn are now re-focused and re-positioned to take advantage of these positive market conditions, some of which may in turn acquire significant market share from us. We cannot assure you that we will be able to maintain our competitive position against current and potential competition, particularly competitors that have greater financial, technical, marketing, sales, service and other resources than we do and therefore may be able to respond more quickly than us to the new or changing opportunities, technologies and customer requirements.

      We also cannot assure you that revenue will continue to grow at previous rates. This revenue growth has occurred while the market for our storage products and solutions has grown more competitive with downward pricing pressures that could negatively impact our revenue growth rate. At the same time, we anticipate and continue to experience further price decline per petabyte for our products which may have an adverse impact on our gross margin if not offset by favorable software mix and higher average selling prices associated with new products. We continue to expect our gross margin to be impacted by factors such as new product introductions and enhancements, add-on software and product mix, discount level, competition and global service investment.

      Continued revenue growth is dependent on the introduction of our new products, including but not limited to the incorporation of new advanced distributed storage technologies from our Spinnaker acquisition into our existing products. As with any product introduction, we face risks in the design, testing, qualification and market acceptance of our new products. If we fail to timely introduce new products, or if there is no or reduced demand for these or our current products, we may experience a decline in revenue. We believe that our strategic investments are targeted at some of the strongest growth areas of the storage market. However, if any storage market trends and emerging standards on which we are basing our assumptions do not materialize as anticipated, our business could be materially adversely affected. Additionally, we plan to invest in the people, processes, and systems necessary to best optimize these growth opportunities. However, we cannot assure you that such investments will achieve our financial objectives. See “Risk Factors” under Item 2.

 	Second Quarter Fiscal 2005 Financial Performance	

 	• 	Our revenues for the second quarter of fiscal 2005 were $375.2 million, a 36.2% increase over the same period a year ago. Our revenues for the six-month period ended October 29, 2004 were $733.6 million, a 36.9% increase over the same period a year ago. While all product areas contributed to revenue growth, NearStore R200, FAS 980, FAS 920 and the FAS 270 were significant contributors.	
 	 	 	
 	• 	Our overall gross margins improved to 61.6% and 60.8%, respectively, in the three and six-month periods ended October 29, 2004 from 59.9% and 59.9%, respectively, in the same periods a year ago. The improvement in our gross margin was primarily attributable to a favorable change in product and add-on software mix, partially offset by the continued investment in our service infrastructure.	
 	 	 	
 	• 	Net income for the second quarter of fiscal 2005 increased 14.3% to $55.3 million compared to net income of $48.4 million for the same period a year ago. Net income for the six-month period ended October 29, 2004 increased 35.4% to $102.2 million compared to net income of $75.5 million for the same period a year ago. Net income for the second quarter and first six months of fiscal 2004 included a nonrecurring income tax benefit of $16.8 million or approximately $0.05 per share associated with a favorable foreign tax ruling.	
 	 	 	
 	• 	Except for the long-term restructuring liabilities of approximately $4.8 million, our balance sheet as of October 29, 2004 remains debt-free, with cash, cash equivalents and investments of $921.7 million (net of $35.3 million and $83.0 million of cash repurchases of our common stock in the three and six-month periods ended October 29, 2004, respectively,) due primarily to our net income and the related cash generated from operations. Days Sales Outstanding was at 53 days as of October 29, 2004 compared to 51 days as of October 31, 2003, reflecting linear quarterly sales and solid credit management. Inventory turns were 16.3 times, improved 34.9% from a year ago. Deferred revenue increased 62.6% to $339.9 million from $209.1 million reported a year ago. Capital purchases of plant, property and equipment for the six-month period ended October 29, 2004 were $49.4 million, which included the $24.1 million site purchase in Research Triangle Park, North Carolina.

 	Discussion and Analysis of Results of Operations	
      Product Revenues — Product revenues increased by 35.0% to $336.8 million for the second quarter of fiscal 2005, from $249.5 million for the second quarter of fiscal 2004. Product revenues increased by 36.3% to

20

Table of Contents
$661.4 million for the six-month period ended October 29, 2004, from $485.3 million for the six-month period ended October 31, 2003. Product revenues growth was across all geographies. This increase in product revenues was specifically attributable to increased software licenses and software subscriptions and an increase in units shipped, as compared to the same period in the prior year.

      Product revenues were favorably impacted by the following factors:
 	 	 	
 	• 	increased revenues from our current product portfolio, such as: FAS980, FAS920, and FAS270 filer products; NearStore ®  R200 nearline storage systems; and NetCache ®  C2100 and C6200 appliances and add-on software;	
 	 	 	
 	• 	increased sales of software subscriptions representing 10.7% and 10.4% of total revenues for the three and six-month periods ended October 29, 2004, respectively and 9.8% and 9.5% of total revenues for the three and six-month periods ended October 31, 2003, respectively;	
 	 	 	
 	• 	increased demand for NetApp’s data protection, mission-critical tier-one storage environments, iSCSI SAN deployments in the Windows environment, distributed enterprise, and unified SAN and NAS solutions; and	
 	 	 	
 	• 	increased sales through indirect channels in absolute dollars, including sales through our resellers, distributors and OEM partners, representing 54.7% and 50.4% of total revenues for three and six-month periods ended October 29, 2004, respectively, and 47.0% and 49.3% of total revenues for the three and six month periods ended October 31, 2003, respectively.	
      Product revenues were negatively impacted by the following factors:
 	 	 	
 	• 	lower-cost-per-megabyte disks;	
 	 	 	
 	• 	declining average selling prices and unit sales of our older products and	
 	 	 	
 	• 	incremental revenue due to an extra week of business in the first half of fiscal 2004 compared to the first half of fiscal 2005.	
      The Spinnaker acquisition did not have a significant impact on our second quarter and the first half of fiscal 2005 revenue. We cannot assure you that we will be able to maintain or increase market demand for our products.

      Service Revenues — Service revenues, which include hardware support, professional services and educational services, increased by 47.5% to $38.4 million in the second quarter of fiscal 2005, from $26.0 million in the second quarter of fiscal 2004. Service revenues increased by 42.2% to $72.2 million in the six-month period ended October 29, 2004, from $50.7 million in the six-month period ended October 31, 2003.

      The increase in absolute dollars was due to the following factors:
 	 	 	
 	• 	an increasing number of enterprise customers, which typically purchase more complete and generally longer-term service packages than our non-enterprise customers;	
 	 	 	
 	• 	a growing installed base resulting in new customer support contracts in addition to support contract renewals by existing customers; and	
 	 	 	
 	• 	growth in professional services revenue.	
      While it is an element of our strategy to expand and offer a more comprehensive, global enterprise support and service solution, we cannot assure you that service revenue will grow at the current rate in the remainder of fiscal 2005.

      Service revenues are generally deferred and, in most cases, recognized ratably over the service obligation periods, which are typically one to three years. Service revenues represented 10.2% and 9.8% of total revenues for the three and six-month periods ended October 29, 2004, respectively and 9.4% and 9.5% of total revenues for the three and six-month periods ended October 31, 2003, respectively.

      International total revenues — International total revenues (including United States exports) increased by 37.8% and 37.7% for the three and six-month periods ended October 29, 2004 as compared to the same periods of fiscal 2004. International total revenues were $155.6 million, or 41.5% of total revenues and $304.9 million, or 41.6% of total revenues for the three and six-month periods ended October 29, 2004, respectively. International total revenues were $112.9 million, or 41.0% of total revenues and $221.4 million, or 41.3% of total revenues for the three and six-month periods ended October 31, 2003, respectively. The increase in international sales was primarily a result of European and Asia Pacific net revenues growth, driven by larger storage implementations, increased demand for our solutions portfolio and higher storage spending in certain geographic regions, as compared to the same periods in the prior fiscal year. We cannot assure you that we will be able to maintain or increase international revenues in the remainder of fiscal 2005.

      Product Gross Margin — Product gross margin increased to 66.8% for the second quarter of fiscal 2005, from 64.7% for the second quarter of fiscal 2004. Product gross margin increased to 65.8% for the six-month period ended October 29, 2004, from 64.3% for the six-month period ended October 31, 2003. Amortization of existing technology included in cost of product revenues was $0.9 million and $1.7 million for the three and six-month periods ended October 29, 2004, respectively, and $1.4 million and $2.7 million for the three and six-month periods ended October 31, 2003, respectively. Estimated future amortization of existing technology to cost of product revenues relating to the Spinnaker acquisition will be $1.7 million for the remainder of fiscal 2005 and $3.4 million for each of fiscal years 2006, 2007, 2008; $2.8 million for fiscal year 2009; and none thereafter.

      Product gross margin was favorably impacted by:
 	 	 	
 	• 	favorable product and add-on software mix;	
 	 	 	
 	• 	competitive pricing solutions with our bundled software and solutions set;	
 	 	 	
 	• 	higher average selling prices for our newer products;	
 	 	 	
 	• 	growth in software subscription upgrades and software licenses due primarily to a larger installed base and an increasing number of new enterprise customers;	
 	 	 	
 	• 	improved operational efficiency;	
 	 	 	
 	• 	lower cost of components and manufacturing overhead; and	
 	 	 	
 	• 	transitional expenses incurred in the three and six-month periods ended October 31, 2003 associated with the initial implementation of a new Enterprise Resource Planning (“ERP”) system, which we did not incur in the three and six-month periods ended October 29, 2004.	
      Product gross margin was negatively impacted by:
 	 	 	
 	• 	increased sales through certain indirect channels, which typically carry a lower gross margin than our direct sales;	
 	 	 	
 	• 	higher disk content with an expanded storage capacity for the higher-end filers and NearStore systems, as resale of disk drives generates lower gross margin;	
 	 	 	
 	• 	sales price reductions due to competitive pricing pressure and selective pricing discounts; and	
 	 	 	
 	• 	lower average selling price of certain add-on software options.	
      Service Gross Margin — Service gross margin increased to 15.9% in the second quarter of fiscal 2005 as compared to 13.9% in the second quarter of fiscal 2004. Service gross margin decreased to 14.7% in the six-month period ended October 29, 2004 as compared to 17.7% in the six-month period ended October 31, 2003. Investments in customer service increased by 44.2% to $32.3 million in the second quarter of fiscal 2005, from $22.4 million in the second quarter of fiscal 2004. Investments in customer service increased by 47.4% to $61.5 million in the six-month period ended October 29, 2004, from $41.7 million in the six-month period ended October 31, 2003.

      The slight improvement in service gross margin for the second quarter of fiscal 2005 compared to the same quarter in fiscal 2004 reflected growth in services revenue partially offset by continued investment in global support infrastructure. The decrease in service gross margin for the six-months ended October 29, 2004 as compared to the same period in the prior year was primarily due to the continued investment in our service infrastructure to support our increasing enterprise customer base partially offset by improved headcount utilization. These investments included additional professional support engineers, increased support center activities and global service partnership programs. Service gross margin will typically experience some variability over time due to the timing of technical support service initiations and renewals and additional investments in our customer support infrastructure. We expect service margin to improve as we begin to see service revenue growth and improved headcount utilization, partially offset by major investments in headcount and logistics as we continue to build out our service capability and capacity to support our growing enterprise customers and new products.

      Sales and Marketing — Sales and marketing expenses consist primarily of salaries, commissions, advertising and promotional expenses, and certain customer service and support costs. Sales and marketing expenses increased 32.8% to $109.1 million for the second quarter of fiscal 2005, from $82.2 million for the second quarter of fiscal 2004. These expenses were 29.1% and 29.8% of total revenues for the second quarters of fiscal 2005 and fiscal 2004, respectively. Sales and marketing expenses increased 31.5% to $212.4 million for the six-month period ended October 29, 2004, from $161.5 million for the six-month period ended October 31, 2003. These expenses were 29.0% and 30.1% of total revenues for the six-month periods ended October 29, 2004 and October 31, 2003, respectively. The increase in absolute dollars was attributed to increased commission expenses resulting from increased revenues, higher performance-based payroll expenses due to higher profitability, higher sales kick-off expenses and the continued worldwide investment in our sales and global service organizations associated with selling complete enterprise solutions and scaling our sales infrastructure, offset by an extra week of business in the first half of fiscal 2004 as compared to the same period in the current year. Amortization of Spinnaker trademarks/tradenames and customer contracts/relationships included in sales and marketing expenses was $0.2 million and $0.4 million for the second quarter and first half of fiscal 2005, respectively, and none in the same periods in fiscal 2004, respectively. Estimated future amortization of trademarks, tradenames, customer contracts and relationships relating to the Spinnaker acquisition will be $0.4 million for the remainder of fiscal year 2005, $0.3 million for fiscal 2006, and $0.1 million for fiscal 2007, respectively, and none thereafter.

      Sales and marketing headcount increased to 1,637 at October 29, 2004 from 1,203 at October 31, 2003. We expect to continue to selectively add sales capacity in an effort to expand domestic and international markets, introduce new products, establish and expand new distribution channels, and increase product and company awareness. We expect to increase our sales and marketing expenses commensurate with future revenue growth.

      Research and Development — Research and development expenses consist primarily of salaries and benefits, prototype expenses, non-recurring engineering charges, fees paid to outside consultants and amortization of capitalized patents. Included in research and development expenses is capitalized patents amortization of $0.5 million and $0.9 million for the three and six-month periods ended October 29, 2004, respectively, as compared to $0.5 million and $0.6 million, respectively, for the same periods in the prior year. Estimated future capitalized patents amortization expenses for the remainder of fiscal 2005 will be $0.9 million, $1.8 million for each of the fiscal years 2006, 2007 and 2008, respectively, and $0.3 million thereafter.

      Research and development expenses increased 29.0% to $40.7 million for the second quarter of fiscal 2005 from $31.5 million for the second quarter of fiscal 2004. These expenses represented 10.8% and 11.4% of total revenues for the second quarters of fiscal 2005 and 2004, respectively. Research and development expenses increased 25.8% to $79.4 million for the six-month period ended October 29, 2004 from $63.1 million for the six-month period ended October 31, 2003. These expenses represented 10.8% and 11.8% of total revenues for the six-month periods ended October 29, 2004 and October 31, 2003, respectively. The increase in research and development expenses was primarily a result of increased headcount, increased ongoing impact of the Spinnaker acquisition, ongoing support of current and future product development and enhancement

Table of Contents
efforts, higher performance-based payroll expenses due to higher profitability, offset by an extra week of expenses in the first half of fiscal 2004 compared to the same period in the current year, cost control and reduction in discretionary spending efforts. Research and development headcount increased to 738 as of October 29, 2004 compared to 567 as of October 31, 2003. For both the six-month periods ended October 29, 2004 and October 31, 2003, no software development costs were capitalized.

      We believe that our future performance will depend in large part on our ability to maintain and enhance our current product line, develop new products that achieve market acceptance, maintain technological competitiveness, and meet an expanding range of customer requirements. We expect to continuously support current and future product development and enhancement efforts, and incur prototyping expenses and non-recurring engineering charges associated with the development of new products and technologies. We intend to continuously broaden our existing product offerings and introduce new products that expand our solutions portfolio.

      We believe that our research and development expenses will increase in absolute dollars for the remainder of fiscal 2005, primarily due to ongoing costs associated with the development of new products and technologies, projected headcount growth and the operating impact of the Spinnaker acquisition as compared to the comparable period in the prior year.

      General and Administrative — General and administrative expenses increased 40.4% to $17.9 million for the second quarter of fiscal 2005, from $12.7 million for the second quarter of fiscal 2004. These expenses represented 4.8% and 4.7% of total revenues for the second quarters of fiscal 2005 and 2004, respectively. General and administrative expenses increased 39.0% to $34.8 million for the six-month period ended October 29, 2004, from $25.0 million for the six-month period ended October 31, 2003. These expenses represented 4.7% and 4.6% of total revenues for the six-month periods ended October 29, 2004 and October 31, 2003, respectively. This increase in absolute dollars was primarily due to expenses associated with expanded regulatory requirements, higher legal expenses and professional fees for general corporate matters, higher performance-based payroll expenses due to higher profitability, partially offset by reduced expenses as a result of one less week of expenses in the three and six-month periods ended October 29, 2004 compared to the same periods in the prior year and higher expenses associated with investments in our enterprise-wide ERP system and back-office infrastructure in the three and six-month periods ended October 31, 2003 which we did not incur in the same periods of the current fiscal year.

      General and administrative headcount increased to 375 at October 29, 2004 from 297 at October 31, 2003. We believe that our general and administrative expenses will increase in absolute dollars for the remainder of fiscal 2005 due to additional expenses related to expanded regulatory requirements as compared to the same period in the prior year. Amortization of Spinnaker covenants not to compete included in general and administrative expenses was $1.3 million and $2.5 million for the three and six-month periods ended October 29, 2004, respectively, and none in the same periods in the prior year. Estimated future amortization of covenants not to compete relating to the Spinnaker acquisition will be $2.5 million in the remainder of fiscal 2005 and $1.5 million for fiscal year 2006, and none thereafter.

      Stock Compensation — Stock compensation expenses were $2.1 million and $4.2 million in the three and six-month periods ended October 29, 2004, respectively and $0.9 million and $1.5 million for the three and six-month periods ended October 31, 2003, respectively. This net increase in stock compensation expenses reflected primarily higher stock compensation relating to the Spinnaker acquisition and restricted stock awards offset by forfeitures of unvested options and restricted stock assumed in the Spinnaker and WebManage acquisitions. Estimated future deferred stock compensation amortization expenses are $3.5 million in the remainder of fiscal 2005, $6.6 million in fiscal 2006, $5.1 million in fiscal 2007 and $3.7 million in fiscal 2008 and none thereafter.

      Restructuring Charges — In fiscal 2002, as a result of continuing unfavorable economic conditions and a reduction in IT spending rates, we implemented two restructuring plans, which included reductions in our workforce and consolidations of our facilities.

     Fiscal 2002 Second Quarter Restructuring Plan

      In August 2001, we implemented the first restructuring plan, which included a reduction in workforce by approximately 200 employees and a consolidation of facilities. The action was required to properly align and manage the business commensurate with our revenue at that time. All functional areas of the Company were affected by the reduction. We completed our actions during the second quarter of fiscal 2002. As a result of this restructuring, we recorded a charge of $8.0 million. The restructuring charge included $4.8 million of severance-related amounts, $2.7 million of committed excess facilities and facility closure expenses, including certain facilities in foreign countries, and $0.5 million in fixed assets write-offs. The reserve balance related to this restructuring charge was $0.3 million at October 29, 2004 was included in other accrued liabilities.

      In the event that the foreign facilities that we vacated are not subleased, we will be obligated for additional total lease payments of approximately $0.3 million as of October 29, 2004 to be payable through January 2006.

      During the second quarter of fiscal 2005, we paid $0.5 million pursuant to final resolution of certain severance-related restructuring accruals. As of October 29, 2004, we have $0.2 million outstanding in our accrued and unpaid severance-related restructuring costs due to changes in estimated costs of certain severance-related matters. We expect to pay or adjust the remaining severance-related restructuring costs pending the outcome of the ultimate resolution of these matters in the next twelve months.

     Fiscal 2002 Fourth Quarter Restructuring Plan

      In April 2002, we completed a restructuring related to the closure of an engineering facility and consolidation of resources to the Sunnyvale headquarters. As a result of this restructuring, we recorded a charge of $5.9 million. The restructuring charge included $0.8 million of severance-related amounts, $4.6 million of committed excess facilities and facility closure expenses, and $0.5 million in fixed assets write-offs. Of the reserve balance at October 29, 2004, $0.6 million was included in other accrued liabilities and the remaining $4.2 million was classified as long-term obligations.

Table of Contents

      In fiscal 2003 and 2004, we updated our assumptions and estimates based on certain triggering events, which resulted in additional net charges of $0.9 million and $1.3 million, respectively, primarily relating to sublease assumptions for our engineering facility. Our estimates are reviewed and revised periodically and may result in a substantial charge to restructuring expense should different conditions prevail than were anticipated in previous management estimates. Such estimates included various assumptions such as the time period over which the facilities will be vacant, expected sublease terms, and expected sublease rates. In the event that the engineering facility is not subleased as anticipated, we will be obligated for an additional total lease payments of $1.8 million as of October 29, 2004 to be payable through November 2010.

      Interest Income — Interest income was $6.1 million and $2.8 million for the second quarters of fiscal 2005 and 2004, respectively. For the six-month periods ended October 29, 2004 and October 31, 2003, interest income was $10.2 million and $5.9 million, respectively. Included in interest income for the second quarter of fiscal 2005 was a $1.3 million interest received on a tax refund. In addition, the increase in interest income was primarily driven by higher cash and investment balances provided by operating activities and higher average interest rates on our investment portfolio. We expect interest income to increase for fiscal 2005 as a result of higher cash and invested balances in a higher interest-rate portfolio environment as we reinvest our securities in longer-term investments and rising average interest rates.

      Other Income (Expense), Net — Other Income (Expense), Net, included net exchange losses from foreign currency transactions, minimal in the second quarter of fiscal 2005 and $0.9 million for the six-month periods ended October 29, 2004. For the three and six-month periods ended October 31, 2003, $1.2 million and $1.3 million, respectively, were included as net exchange losses from foreign currency transactions. The net exchange loss was a result of the volatility of the currency exchange market and increased hedging costs associated with our forward and option activities.

      Net Gain on Investments — Our investments in publicly held companies are generally considered impaired when a decline in the fair value of an investment as measured by quoted market prices is less than its carrying value, and such a decline is not considered temporary. In the six-month period of fiscal 2004, we realized a net gain of $0.1 million, respectively, on the sale of previously impaired investments.

      Provision for Income Taxes — For the three and six-month period ended October 29, 2004, we applied an annual tax rate of 18.1% to pretax income. Our estimate is based on existing tax laws and our current

26

Table of Contents
projections of income (loss) and distributions of income (loss) among different entities and tax jurisdictions, and is subject to change, based primarily on varying levels of profitability.

      Provision for (Benefit from) income taxes for the second quarter of fiscal 2004 included a nonrecurring income tax benefit of $16.8 million or approximately $0.05 per share associated with a favorable foreign tax ruling. This favorable ruling from the Netherlands provides for retroactive benefits dating back to fiscal year 2001 as well as current and future tax rate benefits. This Dutch tax ruling, however, will expire at the end of calendar 2005. There are uncertainties associated with securing a new Dutch tax ruling. As such, we cannot assure you that we will be able to extend this ruling or secure any new favorable rulings, the absence of which may have an adverse impact on the results of our international operations.

Liquidity and Capital Resources

      The following sections discuss the effects of changes in our balance sheet and cash flow, contractual obligations and other commercial commitments, stock repurchase program, capital commitments, other sources and uses of cash flow and potential tax opportunities on our liquidity and capital resources.

 	Balance Sheet and Cash Flows	
      As of October 29, 2004, as compared to April 30, 2004, our cash, cash equivalents, and short-term investments increased by $113.8 million to $921.7 million. We derive our liquidity and capital resources primarily from our cash flow from operations and from working capital. Working capital increased by $98.3 million to $843.3 million as of October 29, 2004, compared to $745.0 million as of April 30, 2004.

      During the first half of fiscal 2005, we recorded net income of $102.2 million as compared to $75.5 million in the same period of the prior year. Non-cash adjustments were higher in the first half of fiscal 2005, including amortization of intangible assets, which was higher by $1.9 million and stock compensation which was higher by $2.7 million, all relating to the Spinnaker acquisition.

      Net sources of cash related to working capital related items increased by $39.2 million in the first half of fiscal 2005 as compared to the same period of fiscal 2004. In addition to higher net income and non-cash adjustments in the first half of fiscal 2005, the primary factors that impacted the period-to-period change in cash flows relating to operating activities included the following:
 	 	 	
 	• 	increase in deferred revenues from higher software subscription and service billings attributable to our continuing shift toward larger enterprise customers;	
 	 	 	
 	• 	an increase in accounts payable in the first half of fiscal 2005 as a result of growth in business volumes;	
 	 	 	
 	• 	increased income taxes payable, primarily reflecting higher profitability in the first half of fiscal 2005 as compared to the same period in the prior year; partially offset by higher worldwide tax payments; and	
 	 	 	
 	• 	decreased prepaid expenses and other assets due to a tax refund of $9.0 million in connection with a carryback of net operating losses generated in fiscal 2000.	
      The above factors were partially offset by the effects of increased accounts receivable balances due to higher revenues in the second quarter of fiscal 2005 compared to the same period in the prior year.

      Capital expenditures for the first half of fiscal 2005 were $49.4 million, which included the $24.1 million site purchase in Research Triangle Park (RTP), North Carolina, as compared to $22.0 million in the same period a year ago. We used net proceeds of $97.6 million and $74.1 million in the six-month periods ended October 29, 2004 and October 31, 2003, respectively, for net purchases/redemptions of short-term investments. In the six-month period ended October 31, 2003, we acquired additional patents for a purchase price of approximately $9.0 million. Investing activities in the six-month period ended October 31, 2003 also included new investments in privately held companies of $0.3 million. We received $0.3 million and $0.4 million in sales proceeds from sales of short and long-term investments in the six-month periods ended October 29, 2004 and October 31, 2003, respectively.

      We used $36.3 million and received $8.4 million in the six-month periods ended October 29, 2004 and October 31, 2003 from net financing activities, which included sales of common stock related to employee stock transactions net of common stock repurchases. We repurchased 4.0 million shares of common stock at a total of $83.0 million during six-month period ended October 29, 2004. During the six-month period ended October 31, 2003, we repurchased 2.7 million shares at a total of $44.9 million. Other financing activities provided $46.7 million and $53.2 million in the six-month periods ended October 29, 2004 and October 31, 2003, respectively, which related to sales of common stock related to employee stock transactions.

      The change in cash flow from financing was primarily due to the effects of higher common stock repurchases partially offset by proceeds from issuance of common stock under employee programs compared to the same period in the prior year. Net proceeds from the issuance of common stock related to employee participation in employee stock programs have historically been a significant component of our liquidity. The extent to which our employees participate in these programs generally increases or decreases based upon changes in the market price of our common stock. As a result, our cash flow resulting from the issuance of common stock related to employee participation in employee stock programs will vary.

 	Stock Repurchase Program	
      On May 13, 2003, we announced that the Board of Directors approved a $150.0 million stock repurchase program to purchase shares of our outstanding common stock in the open market. On May 18, 2004, we announced that the Board authorized an expansion of the program to purchase an additional $200.0 million of outstanding common stock. Any repurchases under our stock repurchase program may be made from time to time in the open market subject to market conditions. The stock repurchase program may be suspended or discontinued at any time. The stock repurchases will be funded from available working capital. The shares repurchased have been taken in as treasury shares and will be held as treasury shares until our Board of Directors designates that these shares be retired or used for some other purpose.

      During fiscal 2004, we repurchased 6.9 million shares of our common stock at an average price of $19.87 per share for an aggregate cost of $136.2 million. During the first half of fiscal 2005, we purchased 4.0 million shares of our common stock at an average price of $20.51 per share for an aggregate purchase price of $83.0 million. As of October 29, 2004, we had purchased 10.9 million shares of our common stock at an average price of $20.11 per share for an aggregate purchase price of $219.2 million since the inception of the stock repurchase program

 	Other Sources and Uses of Cash and Tax Opportunities	
      Under the split dollar insurance arrangement with Daniel J. Warmenhoven (see Note 13) , we will be reimbursed for all premium payments made on these policies. We expect to be reimbursed $10.2 million no later than May 2005.

      The American Jobs Creation Act of 2004 (“the Act”) was signed into law on October 22, 2004. Several provisions of the Act may impact us and the amount of tax we may pay this year and in future years. However, the determination of the level of tax that we will be subject to will hinge on the IRS giving guidance on the Act’s provisions and on the extent to which we choose to pursue some of the elective opportunities under the Act. While the IRS has yet to issue clarifying guidance on the provisions in the Act, we may be impacted by the domestic manufacturing deduction, the repeal of the extra-territorial income exclusion, the temporary deduction for reinvested dividends from controlled foreign corporations, and the extension of the research and experimentation credit. In the case of the offshore repatriation opportunity, we are evaluating whether to pursue the repatriation of controlled foreign corporation cash.

      For the six-month periods ended October 29, 2004 and October 31, 2003, we recorded tax benefits, in the form of reduced payments, of $14.6 million and $11.9 million, respectively, associated with disqualifying dispositions of employee stock options. If stock option exercise patterns change, we may receive less cash from stock option exercises and may not receive the same level of tax benefits in the future, which could cause our cash payments for income taxes to increase.

(1) 	We enter into facilities operating leases in the normal course of business. Substantially all lease agreements have fixed payment terms based on the passage of time. Some lease agreements provide us with the option to renew the lease. Our future operating lease obligations would change if we were to exercise these renewal options and if we were to enter into additional operating lease agreements. Certain facilities operating sublease income of $0.2 million has been included as a reduction of the payment amounts shown in the table. Facilities operating lease payments exclude the leases impacted by the restructurings. The amounts for the leases impacted by the restructurings are included in sub-paragraph (5) below.	
 	 	
(2) 	Venture capital funding commitments includes a quarterly committed management fee based on a percentage of our committed funding to be payable through June 2011.	
 	 	
(3) 	Purchase commitments and other represent agreements to purchase component inventory from our suppliers and/or contract manufacturers that are enforceable and legally binding against us in the short and long-term. Other commitments include examples such as facilities-related and utilities usage minimum cash commitment we expect to pay in the long-term. Purchase commitments and other excludes purchases of good and services we expect to consume in the ordinary course of business in the next twelve months. It also excludes costs that are not reasonably estimable at this time.

(4) 	Under certain communication contracts with major telco companies as well as maintenance contracts with multiple vendors, we are required to pay based on a minimum volume. Such obligations expire through January 2009.	
 	 	
(5) 	These amounts are included on our Consolidated Balance Sheets under Long-term Obligations and Other Accrued Liabilities which is comprised of committed lease payments, operating expenses net of committed and estimated sublease income. The restructuring estimated sublease income included various assumptions such as the time period over which the facilities will be vacant, expected sublease terms, and expected sublease rates. The actual amount paid, if the facility is not subleased, would be increased by $2,066 to be payable through November 2010.	
 	 	
(6) 	The amounts outstanding under these letters of credit relate to workers’ compensation, customs guarantee and a foreign lease.	
 	 	
(7) 	Restricted cash arrangements relate to facility lease requirements, service performance guarantees, customs and duties guarantees, and VAT requirements and are included under Prepaid Expenses and Other and Other Assets on our Consolidated Balance Sheets.	

 	Capital Expenditure Requirements	
      We expect capital expenditures to increase in the future consistent with the growth in our business, as we continue to invest in people, land, buildings, capital equipment and enhancements to our worldwide infrastructure. We expect that our existing facilities and those being developed in Sunnyvale, California, RTP, North Carolina and worldwide are adequate for our requirements over at least the next two years and that additional space will be available as needed. During the first quarter of fiscal 2005, we purchased three buildings in RTP, North Carolina, for $24.1 million. We expect to finance these construction projects, including our commitments under facilities and equipment operating leases, and any required capital expenditures over the next few years through cash from operations and existing cash and investments. In July 2004, we announced that we are the recipient of an award under the new state Job Development Investment Grant (JDIG) program from the state of North Carolina to assist in our expansion of newly acquired offices in RTP, North Carolina.

 	Off-Balance Sheet Arrangements	
      As of October 29, 2004, our financial guarantees of $1.8 million that were not recorded on our balance sheet consisted of standby letters of credits related to workers’ compensation, customs guarantee and a foreign lease.

      As of October 29, 2004, our notional fair values of foreign exchange forward and foreign currency option contracts totaled $194.6 million. We do not believe that these derivatives present significant credit risks, because the counterparties to the derivatives consist of major financial institutions, and we manage the notional amount of contracts entered into with any one counterparty. We do not enter into derivative financial instruments for speculative or trading purposes. Other than the risk associated with the financial condition of the counterparties, our maximum exposure related to foreign currency forward and option contracts is limited to the premiums paid.

      We have entered into indemnification agreements with third parties in the ordinary course of business. 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. These indemnification obligations are considered off-balance sheet arrangements in accordance with FASB, Interpretation 45, of FIN 45,  “Guarantor’s Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others.”  See “Guarantees” in the footnote 14 for further discussion of these indemnification agreements. As of October 29, 2004, we do not have any additional off-balance sheet arrangements, except for operating leases and other contractual obligations outlined under the “Contractual Cash Obligations” table, and has not entered into transactions with special purpose entities.

Table of Contents

 	Liquidity and Capital Resource Requirements	
      Our capital and liquidity requirements depend on numerous factors, including risks relating to fluctuating operating results, continued growth in the network storage and content delivery markets, customer and market acceptance of our products, dependence on new products, rapid technological change, dependence on qualified technical and sales personnel, risk inherent in our international operations, competition, reliance on a limited number of suppliers and contract manufacturers, relationships with strategic partners and resellers, dependence on proprietary technology, intellectual property rights, the value of our investments in equity securities and real estate, and other factors. Based on past performance and current expectations, we believe that our cash and cash equivalents, short-term investments, and cash generated from operations will satisfy our working capital needs, capital expenditures, stock repurchases, contractual obligations, and other liquidity requirements associated with our operations through at least the next twelve months.

Critical Accounting Estimates and Policies

      Our consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of such statements requires us to make estimates and assumptions that affect the reported amounts of revenues and expenses during the reporting period and the reported amounts of assets and liabilities as of the date of the financial statements. Our estimates are based on historical experience and other assumptions that we consider to be appropriate in the circumstances. However, actual future results may vary from our estimates.

      We believe that the following accounting policies are “critical” as defined by the Securities and Exchange Commission, in that they are both highly important to the portrayal of our financial condition and results, and require difficult management judgments and assumptions about matters that are inherently uncertain. We also have other important policies, including those related to derivative instruments and concentration of credit risk. However, these policies do not meet the definition of critical accounting policies because they do not generally require us to make estimates or judgments that are difficult or subjective. These policies are discussed in the Notes to the Consolidated Financial Statements, which are included in our Annual Report on Form 10-K for the fiscal year ended April 30, 2004.

      We believe the accounting policies described below are the ones that most frequently require us to make estimates and judgments, and therefore are critical to the understanding of our results of operations:
 	 	 	
 	• 	revenue recognition and allowances;	
 	 	 	
 	• 	valuation of goodwill and intangibles;	
 	 	 	
 	• 	accounting for income taxes;	
 	 	 	
 	• 	inventory write-down and reserves;	
 	 	 	
 	• 	restructuring accruals;	
 	 	 	
 	• 	impairment losses on investments;	
 	 	 	
 	• 	accounting for stock-based compensation; and	
 	 	 	
 	• 	loss contingencies.	
      These accounting estimates and policies should be read in conjunction with the audited consolidated financial statements and accompanying notes included in our Annual Report on Form 10-K for the year ended April 30, 2004.

New Accounting Standards

      See Note 12 of the Consolidated Condensed Financial Statements for a full description of recent accounting pronouncements including the respective expected dates of adoption and effects on results of operations and financial condition.

Risk Factors

      The following risk factors and other information included in this Form 10-Q should be carefully considered. The risks and uncertainties described below are not the only ones we face. Additional risks and uncertainties not presently known to us or that we presently deem less significant may also impair our business operations. If any of the following risks actually occur, our business, operating results, and financial condition could be materially adversely affected.

 	Factors Beyond Our Control could Cause Our Quarterly Results to Fluctuate.	
      We believe that period-to-period comparisons of our results of operations are not necessarily meaningful and should not be relied upon as indicators of future performance. Many of the factors that could cause our quarterly operating results to fluctuate significantly in the future are beyond our control and include, but are not limited to, the following:
 	 	 	
 	• 	changes in general economic conditions and specific economic conditions in the computer, storage, and networking industries;	
 	 	 	
 	• 	general decrease in global corporate spending on information technology leading to a decline in demand for our products;	
 	 	 	
 	• 	the effects of terrorist activity and international conflicts, which could lead to business interruptions and difficulty in forecasting;	
 	 	 	
 	• 	the level of competition in our target product markets;	
 	 	 	
 	• 	the size, timing, and cancellation of significant orders;	
 	 	 	
 	• 	product configuration and mix;	
 	 	 	
 	• 	the extent to which our customers renew their service and maintenance contracts with us;	
 	 	 	
 	• 	market acceptance of new products and product enhancements;	
 	 	 	
 	• 	announcements, introductions, and transitions of new products by us or our competitors;	
 	 	 	
 	• 	deferrals of customer orders in anticipation of new products or product enhancements introduced by us or our competitors;	
 	 	 	
 	• 	changes in pricing by us in response to competitive pricing actions;	
 	 	 	
 	• 	our ability to develop, introduce, and market new products and enhancements in a timely manner;	
 	 	 	
 	• 	supply constraints;	
 	 	 	
 	• 	technological changes in our target product markets;	
 	 	 	
 	• 	the levels of expenditure on research and development and sales and marketing programs;	
 	 	 	
 	• 	our ability to achieve targeted cost reductions;	
 	 	 	
 	• 	excess facilities;	
 	 	 	
 	• 	future accounting pronouncements and changes in accounting policies; and	
 	 	 	
 	• 	seasonality.	
      In addition, sales for any future quarter may vary and accordingly be inconsistent with our plans. We manufacture products based on a combination of specific order requirements and forecasts of our customer demands. Products are typically shipped within one to four weeks following receipt of an order. In certain circumstances, customers may cancel or reschedule orders without penalty. Product sales are also difficult to forecast because the network storage market is rapidly evolving and our sales cycle varies substantially from customer to customer.

32

Table of Contents

      Due to all of the foregoing factors, it is possible that in one or more future quarters our results may fall below the expectations of public market analysts and investors. In such event, the trading price of our common stock would likely decrease.

 	Our gross margins may vary based on the configuration of our product and service solutions, and such variation may make it more difficult to forecast our earnings.	
      We derive a significant portion of our sales from the resale of disk drives as components of our filers, and the resale market for hard disk drives is highly competitive and subject to intense pricing pressures. Our sales of disk drives generate lower gross margin percentages than those of our filer products. As a result, as we sell more highly configured systems with greater disk drive content, overall gross margin percentages may be negatively affected.

      Our gross margins have been and may continue to be affected by a variety of other factors, including:
 	 	 	
 	• 	demand for storage and content delivery products;	
 	 	 	
 	• 	discount levels and price competition;	
 	 	 	
 	• 	direct versus indirect sales;	
 	 	 	
 	• 	product and add-on software mix;	
 	 	 	
 	• 	the mix of services as a percentage of revenue;	
 	 	 	
 	• 	the mix and average selling prices of products;	
 	 	 	
 	• 	the mix of disk content;	
 	 	 	
 	• 	new product introductions and enhancements;	
 	 	 	
 	• 	excess inventory purchase commitments as a result of changes in demand forecasts and possible product and software defects as we transition our products; and	
 	 	 	
 	• 	the cost of components, manufacturing labor, and quality.	
      Changes in service gross margin may result from various factors such as continued investments in our customer support infrastructure, changes in the mix between technical support services and professional services, as well as the timing of technical support service contract initiations and renewals.

 	A significant percentage of our expenses are fixed, which could materially and adversely affect our net income.	
      Our expense levels are based in part on our expectations as to future sales and a significant percentage of our expenses are fixed. As a result, if sales levels are below expectations or previously higher levels, net income will be disproportionately affected in a material and adverse manner.

 	If we fail to manage our expanding business effectively our operating results could be materially adversely affected.	
      We have experienced growth in fiscal 2004 and the six-month period of fiscal 2005. Our future operating results depend to a large extent on management’s ability to successfully manage expansion and growth, including but not limited to expanding international operations, forecasting revenues, addressing new markets, controlling expenses, implementing infrastructure and systems and managing our assets. In addition, an unexpected decline in the growth rate of revenues without a corresponding and timely reduction in expense growth or a failure to manage other aspects of growth could materially adversely affect our operating results.

 	Our future financial performance depends on growth in the network storage and content delivery markets. If these markets do not continue to grow at the rates at which we forecast growth, our operating results will be materially and adversely impacted.	
      All of our products address the storage and content delivery markets. Accordingly, our future financial performance will depend in large part on continued growth in the storage and content delivery markets and on our ability to adapt to emerging standards in these markets. We cannot assure you that the markets for storage and content delivery will continue to grow or that emerging standards in these markets will not adversely affect the growth of UNIX®, Windows®, and the World Wide Web server markets upon which we depend.

      For example, we provide our open access data retention solutions to customers within the financial services, healthcare, pharmaceuticals and government market segments, industries that are subject to various evolving governmental regulations with respect to data access, reliability and permanence (such as Rule 17(a)(4) of the Securities Exchange Act of 1934, as amended) in the United States and in the other countries in which we operate. If our products do not meet, and continue to comply with, these evolving governmental regulations in this regard, customers in these market and geographical segments will not purchase our products and, therefore, we will not be able to expand our product offerings in these market and geographical segments at the rates for which we have forecast.

      In addition, our business also depends on general economic and business conditions. A reduction in demand for network storage and content delivery caused by weakening economic conditions and decreases in corporate spending have resulted in decreased revenues and lower revenue growth rates. In prior years, the network storage and content delivery market growth declined significantly causing both our revenues and operating results to decline. If the network storage and content delivery markets grow more slowly than anticipated or if emerging standards other than those adopted by us become increasingly accepted by these markets, our operating results could be materially adversely affected.

 	The market price for our common stock has fluctuated significantly in the past and will likely continue to do so in the future.	
      The market price for our common stock has experienced substantial volatility in the past, and several factors could cause the price to fluctuate substantially in the future. These factors include:
 	 	 	
 	• 	fluctuations in our operating results;	
 	 	 	
 	• 	fluctuations in the valuation of companies perceived by investors to be comparable to us;	
 	 	 	
 	• 	economic developments in the network storage market as a whole;	
 	 	 	
 	• 	international conflicts and acts of terrorism;	
 	 	 	
 	• 	a shortfall in revenues or earnings compared to securities analysts’ expectations;	
 	 	 	
 	• 	changes in analysts’ recommendations or projections;	
 	 	 	
 	• 	announcements of new products, applications or product enhancements by us or our competitors;	
 	 	 	
 	• 	changes in our relationships with our suppliers, customers, channel and strategic partners; and	
 	 	 	
 	• 	general market conditions.	
      In addition, the stock market has experienced volatility that has particularly affected the market prices of equity securities of many technology companies. Additionally, certain macroeconomic factors such as changes in interest rates, the market climate for the technology sector, and levels of corporate spending on information technology could also have an impact on the trading price of our stock. As a result, the market price of our common stock may fluctuate significantly in the future and any broad market decline, as well as our own operating results, may materially and adversely affect the market price of our common stock.

 	If we are unable to develop and introduce new products and respond to technological change, if our new products do not achieve market acceptance, or if we fail to manage the transition between our new and old products, our operating results could be materially and adversely affected.	
      Our future growth depends upon the successful development and introduction of new hardware and software products. Due to the complexity of storage subsystems and Internet caching devices, and the difficulty in gauging the engineering effort required to produce new products, such products are subject to significant technical risks. However, we cannot assure you that any of our new products will achieve market acceptance. Additional product introductions in future periods may also impact our sales of existing products. In addition, our new products must respond to technological changes and evolving industry standards. If we are unable, for technological or other reasons, to develop and introduce new products in a timely manner in response to changing market conditions or customer requirements, or if such products do not achieve market acceptance, our operating results could be materially adversely affected.

      In particular, in conjunction with the introduction of our product offerings in the fabric-attached storage market, we introduced products with new features and functionality that address the storage area network market. During fiscal 2003, we introduced iSCSI-enabled unified storage solutions. We also introduced Direct Access File System (“DAFS”) protocol-capable products and NearStore backup and recovery products during fiscal 2002. We face risks relating to these product introductions, including risks relating to forecasting of demand for such products, as well as possible product and software defects and a potentially different sales and support environment associated with selling these new systems. If any of the foregoing occur, our operating results could be adversely affected.

      As new or enhanced products are introduced, we must successfully manage the transition from older products in order to minimize disruption in customers’ ordering patterns, avoid excessive levels of older product inventories, and ensure that enough supplies of new products can be delivered to meet customers’ demands.

 	Our business could be materially adversely affected as a result of a natural disaster, terrorist acts, or other catastrophic events.	
      Our operations, including our suppliers’ and contract manufacturers’ operations, are susceptible to outages due to fire, floods, power loss, power shortages, telecommunications failures, break-ins, and similar events. In addition, our headquarters are located in Northern California, an area susceptible to earthquakes. If any significant disaster were to occur, our ability to operate our business could be impaired.

      Weak economic conditions or terrorist actions could lead to significant business interruptions. If such disruptions result in cancellations of customer orders, a general decrease in corporate spending on information technology, or direct impacts on our marketing, manufacturing, financial functions, or our suppliers’ logistics function, our results of operations and financial condition could be adversely affected.

 	We depend on attracting and retaining qualified technical and sales personnel. If we are unable to attract and retain such personnel, our operating results could be materially and adversely impacted.	
      Our continued success depends, in part, on our ability to identify, attract, motivate, and retain qualified technical and sales personnel. Because our future success is dependent on our ability to continue to enhance and introduce new products, we are particularly dependent on our ability to identify, attract, motivate, and retain qualified engineers with the requisite education, backgrounds, and industry experience. Competition for qualified engineers, particularly in Silicon Valley, can be intense. The loss of the services of a significant number of our engineers or sales people could be disruptive to our development efforts or business relationships and could materially adversely affect our operating results.

 	Risks inherent in our international operations could have a material adverse effect on our operating results.	
      We conduct business internationally. For the three and six-month period ended October 29, 2004, approximately 41.5% and 41.6%, respectively, of our total revenues was from international customers (including U.S. exports). Accordingly, our future operating results could be materially adversely affected by a variety of factors, some of which are beyond our control, including regulatory, political, or economic conditions in a specific country or region, trade protection measures and other regulatory requirements, government spending patterns, and acts of terrorism and international conflicts.

      Our international sales are denominated in U.S. dollars and in foreign currencies. An increase in the value of the U.S. dollar relative to foreign currencies could make our products more expensive and, therefore, potentially less competitive in foreign markets. For international sales and expenditures denominated in foreign currencies, we are subject to risks associated with currency fluctuations. We hedge risks associated with foreign currency transactions in order to minimize the impact of changes in foreign currency exchange rates on earnings. We utilize forward and option contracts to hedge our currency exposure associated with certain assets and liabilities as well as anticipated foreign currency cash flow. All balance sheet hedges are marked to market through earnings every period, while gains and losses on cash flow hedges are recorded in other comprehensive income. These hedges attempt to reduce, but do not always entirely eliminate, the impact of currency exchange movements. Factors that could have an impact on the effectiveness of our hedging program include the accuracy of forecasts and the volatility of foreign currency markets. There can be no assurance that such hedging strategies will be successful and that currency exchange rate fluctuations will not have a material adverse effect on our operating results. We believe that these foreign currency hedging contracts will not subject us to significant credit risks, because the counterparties to the derivatives consist of major financial institutions, and we manage the notional amount of contracts entered into with any one counterparty.

      Additional risks inherent in our international business activities generally include, among others, longer accounts receivable payment cycles and difficulties in managing international operations. Such factors could materially adversely affect our future international sales and, consequently, our operating results.

      Potentially adverse tax consequences could also negatively impact the operating and financial results from international operations. International operations currently benefit from a tax ruling concluded in the Netherlands. The Dutch tax ruling, however, will expire at the end of calendar 2005. There are uncertainties associated with securing a new Dutch tax ruling.

      Although operating results have not been materially adversely affected by seasonality in the past, because of the significant seasonal effects experienced within the industry, particularly in Europe, our future operating results could be materially adversely affected by seasonality.

      We cannot assure you that we will be able to maintain or increase international market demand for our products.

 	An increase in competition could materially adversely affect our operating results.	
      The storage and content delivery markets are intensely competitive, and are characterized by rapidly changing technology.

      In the storage market, our FAS appliances and associated storage software portfolio compete primarily with storage system products and data management software from EMC Corporation, Hitachi Data Systems, Hewlett-Packard Company (including the integrated Compaq Computer Corporation), IBM Corporation, and Sun Microsystems, Inc. We have also historically encountered less-frequent competition from companies including Dell, Engenio Information Technologies, Inc. (formerly the Storage Systems Group of LSI Logic Corp.), StorageTek Technology Corporation, Silicon Graphics, Inc., and Xiotech Corporation. In the nearline storage market, which includes the disk-to-disk backup and regulated data storage segments, our NearStore appliances compete primarily against products from EMC and StorageTek. Our NearStore appliances also compete indirectly with traditional tape backup solutions in the broader data backup/recovery space.

36

Table of Contents

      In the content delivery market, our NetCache appliances and content delivery software compete against caching appliance and content delivery software vendors including BlueCoat Systems (formerly CacheFlow, Inc.), and Cisco Systems, Inc. Our NetCache business is also subject to indirect competition from content delivery service products such as those offered by Akamai Technologies.

      Additionally, a number of new, privately held companies are currently attempting to enter the storage systems and data management software markets, the nearline storage market, and the caching and content delivery markets, some of which may become significant competitors in the future.

      We believe that the principal competitive factors affecting the storage and content delivery markets include product benefits such as response time, reliability, data availability, scalability, ease of use, price, multiprotocol capabilities, and global service and support. To date, we have been able to compete successfully with our principal competitors in large part based on the product benefits that we believe result from the superior technology of our products. We must continue to maintain and enhance this technological advantage over our competitors. Otherwise, if those competitors with greater financial, marketing, service, support, technical and other resources were able to offer products that matched or surpassed the technological capabilities of our products, these competitors would, by virtue of these greater resources, gain a competitive advantage over us that could lead to greater sales for these competitors at the expense of our own market share, which would have a material adverse effect on our business, financial condition and results of operations.

      Increased competition could also result in price reductions, reduced gross margins, and loss of market share, any of which could materially adversely affect our operating results. Our competitors may be able to respond more quickly than we can to new or emerging technologies and changes in customer requirements, or devote greater resources to the development, promotion, sale, and support of their products. In addition, current and potential competitors have established or may establish cooperative relationships among themselves or with third parties. Accordingly, it is possible that new competitors or alliances among competitors may emerge and rapidly acquire significant market share. We cannot assure you that we will be able to compete successfully against current or future competitors. Competitive pressures we face could materially adversely affect our operating results.

 	We rely on a limited number of suppliers, and any disruption or termination of these supply arrangements could delay shipment of our products and could materially and adversely affect our operating results.	
      We rely on a limited number of suppliers of several key components utilized in the assembly of our products. We purchase most of our disk drives through a single supplier. We purchase computer boards and microprocessors from a limited number of suppliers. Our reliance on a limited number of suppliers involves several risks, including:
 	 	 	
 	• 	a potential inability to obtain an adequate supply of required components because we do not have long-term supply commitments;	
 	 	 	
 	• 	supplier capacity constraints;	
 	 	 	
 	• 	price increases;	
 	 	 	
 	• 	timely delivery; and	
 	 	 	
 	• 	component quality.	
      Component quality is particularly significant with respect to our suppliers of disk drives. In order to meet product performance requirements, we must obtain disk drives of extremely high quality and capacity. In addition, there are periodic supply-and-demand issues for disk drives, microprocessors, and for semiconductor memory components, which could result in component shortages, selective supply allocations, and increased prices of such components. We cannot assure you that we will be able to obtain our full requirements of such components in the future or that prices of such components will not increase. In addition, problems with respect to yield and quality of such components and timeliness of deliveries could occur. Disruption or

37

Table of Contents
termination of the supply of these components could delay shipments of our products and could materially adversely affect our operating results. Such delays could also damage relationships with current and prospective customers.

      In addition, we license certain technology and software from third parties that is incorporated into our products. If we are unable to obtain or license the technology and software on a timely basis, we will not be able to deliver products to our customers in a timely manner.

 	The loss of any contract manufacturers or the failure to accurately forecast demand for our products or successfully manage our relationships with our contract manufacturers could negatively impact our ability to manufacture and sell our products.	
      We currently rely on several contract manufacturers to manufacture most of our products. Our reliance on our third-party contract manufacturers reduces our control over the manufacturing process, exposing us to risks, including reduced control over quality assurance, production costs, and product supply. If we should fail to effectively manage our relationships with our contract manufacturers, or if our contract manufacturers experience delays, disruptions, capacity constraints, or quality control problems in their manufacturing operations, our ability to ship products to our customers could be impaired and our competitive position and reputation could be harmed. Qualifying a new contract manufacturer and commencing volume production are expensive and time-consuming. If we are required to change contract manufacturers or assume internal manufacturing operations, we may lose revenue and damage our customer relationships. If we inaccurately forecast demand for our products, we may have excess or inadequate inventory, or incur cancellation charges or penalties, which could adversely impact our operating results. As of October 29, 2004, we had no purchase commitment for such excess inventory.

      We intend to regularly introduce new products and product enhancements, which will require us to rapidly achieve volume production by coordinating with our contract manufacturers and suppliers. We may need to increase our material purchases, contract manufacturing capacity, and internal test and quality functions to meet anticipated demand. The inability of our contract manufacturers to provide us with adequate supplies of high-quality products, or the inability to obtain raw materials, could cause a delay in our ability to fulfill orders.

 	If we are unable to maintain our existing relationships and develop new relationships with major strategic partners, our revenue may be impacted negatively.	
      An element of our strategy to increase revenue is to strategically partner with major third-party software and hardware vendors that integrate our products into their products and also comarket our products with these vendors. A number of these strategic partners are industry leaders that offer us expanded access to segments of the storage market. There is intense competition for attractive strategic partners, and even if we can establish strategic relationships with these partners, we cannot assure you that these partnerships will generate significant revenue or that the partnerships will continue to be in effect for any specific period of time.

      We intend to continue to establish and maintain business relationships with technology companies to accelerate the development and marketing of our storage solutions. To the extent we are unsuccessful in developing new relationships and maintaining our existing relationships, our future revenue and operating results could be impacted negatively. In addition, the loss of a strategic partner could have a material adverse effect on the progress of our new products under development with that partner.

 	We may incur problems with current or future equity investments and acquisitions, and these investments may not achieve our objectives.	
      From time to time, we make equity investments for the promotion of business and strategic objectives. We have already made strategic investments in a number of network storage-related technology companies. Equity investments may result in the loss of investment capital. The market price and valuation of our equity investments in these companies may fluctuate due to market conditions and other circumstances over which

38

Table of Contents
we have little or no control. To the extent that the fair value of these securities is less than our cost over an extended period of time, our results of operations and financial position could be negatively impacted.

      As part of our strategy, we are continuously evaluating opportunities to buy other businesses or technologies that would complement our current products, expand the breadth of our markets, or enhance our technical capabilities. We have acquired three companies since the beginning of fiscal 2001, including the acquisition of Spinnaker Networks, Inc., for approximately $306.0 million. We completed the Spinnaker acquisition during the fourth quarter of fiscal 2004 and have completed integrating the acquired operations and products from this acquisition into our operations. We may engage in future acquisitions that dilute our stockholders’ investments and cause us to use cash, to incur debt, or to assume contingent liabilities.

      Acquisitions of companies entail numerous risks, and we may not be able to successfully integrate acquired operations and products or realize anticipated synergies, economies of scale, or other value. In addition, we may experience a diversion of management’s attention, the loss of key employees of acquired operations, or the inability to recover strategic investments in development stage entities. Any such problems could have a material adverse effect on our business, financial condition, and results of operations.

      In addition, we adopted SFAS No. 142 “Goodwill and Other Intangible Assets,” which changes the accounting for goodwill from an amortization method to an impairment-only approach. As of October 29, 2004, the fair value for each of our reporting units exceeded the reporting unit’s carrying amount and no impairment was recognized. On an ongoing basis, goodwill is reviewed annually for impairment (or more frequently if indicators of impairment arise). There had been no impairment of goodwill and intangible assets as of the end of the second quarter of fiscal 2005. There can be no assurance that future impairment tests will not result in a charge to earnings.

 	We rely and will increasingly rely on our indirect sales channel for a significant portion of our revenue. If we are unable to effectively manage this sales channel, we will not be able to maintain or increase our revenue as we have forecasted, which would have a material adverse impact on our business, financial condition and results of operations.	
      We market and sell our storage solutions directly through our worldwide sales force and indirectly through channels such as value-added resellers (“VARs”), systems integrators, distributors and strategic business partners and derive a significant portion of our revenue from these indirect channel partners. However, in order for us to maintain our current revenue sources and grow our revenue as we have forecasted, we must effectively manage our relationships with these indirect channel partners. To do so, we must attract and retain a sufficient number of qualified channel partners to successfully market our products. However, because we also sell our products directly to customers through our sales force, on occasion we compete with our indirect channels for sales of our products to our end customers, competition that could result in conflicts with these indirect channel partners and make it harder for us to attract and retain these indirect channel partners. At the same time, our indirect channel partners may develop and offer products of their own that are competitive to ours. Or, because our reseller partners generally offer products from several different companies, including products of our competitors, these resellers may give higher priority to the marketing, sales and support of our competitors’ products than ours. If we fail to manage effectively our relationships with these indirect channel partners to minimize channel conflict and continue to evaluate and meet our indirect sales partners’ needs with respect to our products, we will not be able to maintain or increase our revenue as we have forecasted, which would have a materially adverse affect on our business, financial condition, and results of operations.

 	Undetected software, hardware errors, or failures found in new products may result in loss of or delay in market acceptance of our products, which could increase our costs and reduce our revenues.	
      Our products may contain undetected software, hardware errors, or failures when first introduced or as new versions are released. Despite testing by us and by current and potential customers, errors may not be found in new products until after commencement of commercial shipments, resulting in loss of or delay in market acceptance, which could materially adversely affect our operating results.

 	If actual results or events differ materially from our estimates and assumptions, our reported financial condition and results of operations for future periods could be materially affected.	
      The preparation of the consolidated financial statements and related disclosure in conformity with accounting principles generally accepted in the United States of America requires management to establish policies that contain estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Note 2 of the Notes to Consolidated Financial Statements of the Annual Report on Form 10-K for the year ended April 30, 2004 describes the significant accounting policies essential to preparing our consolidated financial statements. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosures. We base our estimates on historical experience and assumptions that we believe to be reasonable under the circumstances. Actual future results may differ materially from these estimates. We evaluate, on an ongoing basis, our estimates and assumptions. In addition, see our Critical Accounting Estimates and Policies under Item 7 of the Annual Report on Form 10-K for the year ended April 30, 2004.

 	If we are unable to protect our intellectual property, we may be subject to increased competition that could materially adversely affect our operating results.	
      Our success depends significantly upon our proprietary technology. We rely on a combination of copyright and trademark laws, trade secrets, confidentiality procedures, contractual provisions, and patents to protect our proprietary rights. We seek to protect our software, documentation, and other written materials under trade secret, copyright, and patent laws, which afford only limited protection. Some U.S. trademarks and some U.S.-registered trademarks are registered internationally as well. We will continue to evaluate the registration of additional trademarks as appropriate. We generally enter into confidentiality agreements with our employees and with our resellers, strategic partners, and customers. We currently have multiple U.S. and international patent applications pending and multiple U.S. patents issued. The pending applications may not be approved and if patents are issued, such patents may be challenged. If such challenges are brought, the patents may be invalidated. We cannot assure you that we will develop proprietary products or technologies that are patentable, that any issued patent will provide us with any competitive advantages or will not be challenged by third parties, or that the patents of others will not materially adversely affect our ability to do business.

      Litigation may be necessary to protect our proprietary technology. Any such litigation may be time-consuming and costly. Despite our efforts to protect our proprietary rights, unauthorized parties may attempt to copy aspects of our products or to obtain and use information that we regard as proprietary. In addition, the laws of some foreign countries do not protect proprietary rights to as great an extent as do the laws of the U.S. We cannot assure you that our means of protecting our proprietary rights will be adequate or that our competitors will not independently develop similar technology, duplicate our products, or design around patents issued to us or other intellectual property rights of ours.

      We are subject to intellectual property infringement claims. We may, from time to time, receive claims that we are infringing third parties’ intellectual property rights. Third parties may in the future claim infringement by us with respect to current or future products, patents, trademarks, or other proprietary rights. We expect that companies in the appliance market will increasingly be subject to infringement claims as the number of products and competitors in our industry segment grows and the functionality of products in different industry segments overlaps. Any such claims could be time-consuming, result in costly litigation, cause product shipment delays, require us to redesign our products or require us to enter into royalty or licensing agreements, any of which could materially adversely affect our operating results. Such royalty or licensing agreements, if required, may not be available on terms acceptable to us or at all.

 	Changes in financial accounting standards or practices may cause adverse unexpected fluctuations and affect our reported business and financial results.	
      Future regulatory changes, such as the FASB’s pending proposals to mandate the expensing of stock options, would require us to record charges to earnings for employee stock option grants and could adversely

40

Table of Contents
affect our business and financial results. Should this proposed statement be finalized, it will result in lower reported earnings per share which could negatively impact our future stock price, and the effectiveness of current outstanding stock options in retaining key personnel. In addition, this could also impact our ability or future practice of utilizing broad-based employee stock plans to attract, reward, and retain employees, which could also adversely impact our operations.

      In addition, the FASB has proposed a choice of valuation models to estimate the fair value of employee stock options. These models, including the Black-Scholes option-pricing model, use varying methods, inputs and assumptions selected across companies. If another party asserts that the fair value of our employee stock options are misstated, securities class action litigation could be brought against us or the market price of our common stock could decline or both could occur. As a result of these changes, we could incur losses and our operating results and gross margins may be below our expectations and those of investors and stock market analysts.

 	Our business is subject to changing regulation of corporate governance and public disclosure that has increased both our costs and the risk of noncompliance. We may have difficulty implementing in a timely manner the processes necessary to allow us to assess and report on the effectiveness of our internal financial controls under the Sarbanes-Oxley Act.	
      Because our common stock is publicly traded, we are subject to certain rules and regulations of federal, state and financial market exchange entities charged with the protection of investors and the oversight of companies whose securities are publicly traded. These entities, including the Public Company Accounting Oversight Board, the SEC and NASDAQ, have recently issued new requirements and regulations and continue developing additional regulations and requirements in response to recent corporate scandals and laws enacted by Congress, most notably the Sarbanes-Oxley Act of 2002. Our efforts to comply with these new regulations have resulted in, and are likely to continue resulting in, increased general and administrative expenses and diversion of management time and attention from revenue-generating activities to compliance activities.

      Pursuant to Section 404 of the Sarbanes-Oxley Act, we will be required to furnish a report on our management’s assessment of the design and effectiveness of our system of internal controls over financial reporting as part of our Annual Report on Form 10-K beginning with the fiscal year ending April 29, 2005. Our auditors will also be required to attest to, and report on, our management’s assessment. In order to issue their report, our management must document both the design of our system of internal controls and our testing processes that support our management’s evaluation and conclusion. During the course of testing, we may identify deficiencies, which we may not be able to remediate in time to meet the reporting deadline imposed by Section 404 of the Sarbanes-Oxley Act and the costs of which may have a material adverse impact of our results of operations. In addition, if we fail to maintain the adequacy of our internal controls, as such standards are modified, supplemented or amended from time to time, we may not be able to ensure that our management can conclude on an ongoing basis that we have effective internal controls and we may not be able to retain independent auditors with sufficient resources to attest to and report on our internal controls. Moreover, our auditors may not agree with our management’s assessment and may send us a deficiency notice that we are unable to remediate on a timely basis. If we are unable to assert as of April 29, 2005 that we have effective internal controls, our investors could lose confidence in the accuracy and completeness in our financial reports which in turn could cause our stock price to decline.

Item 3.	Quantitative and Qualitative Disclosures About Market Risk	
      We are exposed to market risk related to fluctuations in interest rates, market prices and foreign currency exchange rates. We use certain derivative financial instruments to manage these risks. We do not use derivative financial instruments for speculative or trading purposes. All financial instruments are used in accordance with management-approved policies.

41

Table of Contents

Market Interest and Interest Income Risk

      Interest and Investment Income — As of October 29, 2004, we had short-term investments of $664.4 million. Our investment portfolio primarily consists of highly liquid investments with original maturities at the date of purchase of greater than three months, which are classified as available-for-sale, and investment in marketable equity securities in primarily technology companies. These highly liquid investments, consisting primarily of government and corporate debt securities, are subject to interest rate and interest income risk and will decrease in value if market interest rates increase. A hypothetical 10 percent increase in market interest rates from levels at October 29, 2004 would cause the fair value of these short-term investments to decline by approximately $1.5 million. By policy, we limit our exposure to longer term investments, and a substantial majority of our investment portfolio has maturities of less than three years. Because we have the ability to hold these investments until maturity we would not expect any significant decline in value of our investments caused by market interest rate changes. Declines in interest rates over time will, however, reduce our interest income. We do not use derivative financial instruments in our investment portfolio.

Market Price Risk

      Equity Securities — We are also exposed to market price risk on our equity securities included in our short-term investments, which are primarily in publicly traded companies in the volatile high-technology industry sector.

      We do not attempt to reduce or eliminate our market exposure on these securities and, as a result, the amount of income and cash flow that we ultimately realize from our investment in future periods may vary materially from the current fair value. A 50% adverse change in the equity price would result in an immaterial decrease in the fair value of our equity security as of October 29, 2004.

      The hypothetical changes and assumptions discussed above will be different from what actually occurs in the future. Furthermore, such computations do not anticipate actions that may be taken by management, should the hypothetical market changes actually occur over time. As a result, the effect on actual earnings in the future will differ from those described above.

Foreign Currency Exchange Rate Risk

      We hedge risks associated with foreign currency transactions in order to minimize the impact of changes in foreign currency exchange rates on earnings. We utilize forward and option contracts to hedge against the short-term impact of foreign currency fluctuations on certain assets and liabilities denominated in foreign currencies. All balance sheet hedges are marked to market through earnings every period. We also use foreign exchange forward contracts to hedge foreign currency forecasted transactions related to certain sales and operating expenses. These derivatives are designated as cash flow hedges under SFAS No. 133. For cash flow hedges, the gains or losses were included in other comprehensive income at October 29, 2004.

      We do not enter into foreign exchange contracts for speculative or trading purposes. In entering into forward and option foreign exchange contracts, we have assumed the risk that might arise from the possible inability of counterparties to meet the terms of their contracts. We attempt to limit our exposure to credit risk by executing foreign exchange contracts with credit worthy multinational commercial banks. All contracts have a maturity of less than one year.

Item 4.	Controls and Procedures	
      Disclosure Controls are procedures designed to ensure that information required to be disclosed in our reports filed under the Exchange Act, such as this Quarterly Report, is recorded, processed, summarized and reported within the time periods specified in the U.S. Securities and Exchange Commission’s rules and forms. Disclosure Controls are also designed to ensure that such information is accumulated and communicated to our management, including the CEO and CFO, as appropriate to allow timely decisions regarding required disclosure.

      Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, we conducted an evaluation of the effectiveness of the design and operation of 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, as of the end of the period covered by this report (the “Evaluation Date”). Based on this evaluation, our principal executive officer and principal financial officer concluded as of the Evaluation Date that our disclosure controls and procedures were effective such that the information relating to Network Appliance, including our consolidated subsidiaries, required to be disclosed in our Securities and Exchange Commission (“SEC”) reports (i) is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms, and (ii) is accumulated and communicated to Network Appliance’s management, including our principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure.

      There was no change in our internal control over financial reporting that occurred during the period covered by this Quarterly Report that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Item 2.	Unregistered Sales of Equity Securities and Use of Proceeds	

 	Issuer Purchases of Equity Securities in the Second Quarter of Fiscal 2005	
      On May 13, 2003, we announced that the Board of Directors approved a $150.0 million stock repurchase program to purchase shares of our outstanding common stock in the open market. On May 18, 2004, we announced that the Board authorized an expansion of the program to purchase an additional $200.0 million of outstanding common stock. Total authorized stock purchase spending may be up to $350.0 million. The repurchases were recorded as treasury stock and resulted in a reduction of stockholders’ equity. The stock repurchase program may be suspended or discontinued at any time. The duration of the repurchase program is open-ended. Under the program, we may purchase shares of common stock through open market transactions at prices deemed appropriate by management. The timing and amount of repurchase transactions under this program will depend on market conditions and corporate and regulatory considerations. The purchases will be funded from available working capital.

      During fiscal 2004, we repurchased 6.9 million shares of our common stock at an average price of $19.87 per share for an aggregate cost of $136.2 million. During the first half of fiscal 2005, we purchased 4.0 million shares of our common stock at an average price of $20.51 per share for an aggregate purchase price of $83.0 million. As of October 29, 2004, we had purchased 10.9 million shares of our common stock at an average price of $20.11 per share for an aggregate purchase price of $219.2 million since the inception of the stock repurchase program
