NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)

1. Description of Business and Basis of Presentation

The Company

PortalPlayer, Inc. (the “Company”) was incorporated in California on May 17, 1999 and reincorporated in Delaware in October 2004. The Company designs, develops and markets comprehensive platform solutions, including a system-on-chip and firmware, for manufacturers of personal media players.

Principles of Consolidation and Basis of Presentation

The unaudited condensed consolidated financial statements included herein have been prepared in accordance with the published rules and regulations of the Securities and Exchange Commission (“SEC”) applicable to interim financial information. Certain information and footnote disclosures included in financial statements prepared in accordance with generally accepted accounting principles have been omitted in these interim statements as allowed by such SEC rules and regulations. However, management believes that the disclosures herein are adequate to make the information presented not misleading. The unaudited condensed consolidated financial statements included in this Form 10-Q have been derived from and should be read in conjunction with the audited consolidated financial statements and notes thereto for the year ended December 31, 2004, included in the Company’s Annual Report on Form 10-K, filed with the SEC on March 21, 2005.

Certain prior year amounts have been reclassified to conform to the current presentation. These reclassifications had no effect on reported income or losses.

The unaudited condensed consolidated financial statements include the accounts of PortalPlayer, Inc. and its subsidiaries. All significant intercompany balances and transactions have been eliminated. The unaudited condensed consolidated financial statements contained herein reflect all adjustments (which include only normal, recurring adjustments), which are, in the opinion of management, necessary to state fairly the results for the periods presented. The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. The results for the three-month period ended March 31, 2005 are not necessarily indicative of the results to be expected for the entire fiscal year ending December 31, 2005.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to a concentration of credit risk consist primarily of trade receivables. The Company provides credit, in the normal course of business, to a number of companies and performs credit evaluations of its customers. As of March 31, 2005 and December 31, 2004, approximately 94.7% and 97.7%, respectively, of gross accounts receivable were concentrated with a group of affiliated companies, collectively referred to as Inventec. For the periods ended March 31, 2005 and March 31, 2004, Inventec accounted for 81.6% and 92.3%, respectively, of revenue. In connection with contracts to this customer, the Company is required to be prepared to ship additional quantities of inventory in excess of existing orders within specified periods in the future.

The Company is dependent on two suppliers for substantially all of its inventory requirements. One supplier is also a stockholder of the Company (see Note 7). The inability of a supplier to fulfill the production requirements of the Company on a timely basis could negatively impact future results. Although there are other suppliers that could provide similar services, a change in supplier could cause delays in the Company’s products and possible loss of revenue.

Reportable Segments

The Company currently operates in one reportable segment, the designing, developing and marketing of comprehensive platform solutions, including a system-on-chip and firmware, for manufacturers of personal media players. The Company’s chief operating decision maker is the CEO.

2. Stock-Based Compensation

The Company accounts for its stock-based awards to employees using the intrinsic value method in accordance with Accounting Principles Board (or, APB) Opinion No. 25, “Accounting for Stock Issued to Employees”, and its related interpretations. The Company accounts for stock-based awards to non-employees in accordance with Emerging Issues Task Force (or, EITF) Issue No. 96-18. Statement of Financial Accounting Standards No. 123, “Accounting for Stock-Based Compensation” (or, SFAS 123), requires the Company to disclose pro forma information regarding what its net income (loss) would have been if equity awards to employees had been accounted for using the fair value method of SFAS 123 rather than the intrinsic value method of APB 25. The pro forma information is as follows (in thousands, except per-share amounts):

The Company’s calculation of additional stock-based compensation expense was made using a Black-Scholes option-pricing model with the following assumptions:

The above pro forma disclosures are not necessarily representative of the effects on reported net income or loss for future years.

In December 2004, the Financial Accounting Standards Board issued SFAS No. 123 (revised 2004), “ Share-Based Payment ” (or, SFAS 123R), which replaces SFAS No. 123, “ Accounting for Stock-Based Compensation ” (or, SFAS 123), and supersedes APB Opinion No. 25, “ Accounting for Stock Issued to Employees .” SFAS 123R requires all share-based payments to employees, including grants of employee stock options, to be recognized in the financial statements based on their fair values. The pro forma disclosures previously permitted under SFAS 123 no longer will be an alternative to financial statement recognition. On April 14, 2005, the SEC adopted a new rule that amended the compliance dates for FAS 123R such that the Company must adopt the new standard effective January 1, 2006. Under SFAS 123R, the Company must determine the appropriate fair value model to be used for valuing share-based payments, the amortization method for compensation cost, the assumed forfeiture rate and the transition method to be used at the date

of adoption. The transition methods include prospective and retroactive adoption options. Under the retroactive options, prior periods may be restated either as of the beginning of the year of adoption or for all periods presented. The prospective method requires that compensation expense be recorded for all unvested stock options and restricted stock at the beginning of the first quarter of adoption of SFAS 123R, while the retroactive methods would record compensation expense for all unvested stock options and restricted stock beginning with the first period restated. The Company is evaluating the requirements of SFAS 123R and expects that the adoption of SFAS 123R will have a material impact on its consolidated results of operations and earnings per share. The Company has not yet determined the method of adoption or the effect of adopting SFAS 123R, and has not determined whether the adoption will result in amounts that are similar to the current pro forma disclosures under SFAS 123.

3. Net Income (Loss) Per Share

The calculation of diluted net income per share excludes all anti-dilutive shares. For the three months ended March 31, 2005 and 2004, the number of anti-dilutive shares, as calculated based on the average closing price of our common stock for the period, amounted to approximately 76,584 and zero shares, respectively.

5. Commitments and Contingencies

Litigation

The Company is subject to various claims, which arise in the course of business. In the opinion of management, the ultimate disposition of these claims will not have a material adverse effect on the Company’s consolidated financial position, liquidity or results of operations.

Guarantees

Certain of the Company’s customer agreements contain infringement indemnification provisions for claims from third parties related to the Company’s intellectual property. These indemnification provisions are accounted for in accordance with SFAS No. 5. The Company has entered into indemnification agreements with its directors and officers in which the Company has agreed to indemnify such directors and officers to the fullest extent allowable under Delaware law if any such director or officer is made a party to any action or threatened with any action as a result of such person’s service or having served as an officer, director, employee or agent of PortalPlayer, Inc. or having served, at the Company’s request, as an officer, director, employee or agent of another company. The maximum potential amount of future payments that the Company could be required to make under the indemnification agreements is unlimited; however, the Company has director’s and officer’s liability insurance policies that, in most cases, would limit the potential exposure and enable the Company to recover a portion of any future amounts paid. The estimated fair value of these indemnification provisions is minimal. To date, the Company has not incurred any costs related to any claims under these provisions and no amounts have been accrued in the accompanying financial statements.

Warranty

The Company provides a warranty on its products for a period of twelve to fifteen months from the date of sale, and provides for warranty costs at the time of sale based on historical activity for the prior 12 months. The determination of such provisions requires the Company to make estimates of the frequency and extent of warranty activity and estimated future costs to replace the products under warranty. If actual warranty activity and/or repair and replacement costs differ significantly from these estimates, adjustments to recognize additional cost of sales may be required in future periods. The following table summarizes the activity related to the warranty reserve during the three months ended March 31, 2005 and 2004:

6. Comprehensive Income (Loss)

Comprehensive income (loss) is defined as the change in equity of a Company during a period from transactions and other events and circumstances excluding transactions resulting from investments from owners and distributions to owners. Comprehensive income (loss) includes the Company’s net income (loss), as well as unrealized gain (loss) on available-for-sale investments. Comprehensive income (loss) for the three months ended March 31, 2005 and 2004, respectively, is as follows:

7. Related Party Transactions

One of the Company’s suppliers is also a stockholder that the Company considered a related party during the three-month period ended March 31, 2004. This supplier was not considered a related party during the period ended March 31, 2005 due to its decreased percentage of total ownership of the Company following the issuance of shares as part of the Company’s November 2004 initial public offering. The Company purchased inventory and services of $16.3 million and $4.6 million from this supplier in the three months ended March 31, 2005 and 2004, respectively.

8. Subsequent Event

In May 2005, the Company granted to employees options to purchase approximately 907,472 shares of the Company’s common stock, and additionally granted approximately 165,109 shares of restricted stock to employees. The exercise price of the options granted is $16.68, which is equal to the fair value of the common stock at the grant date. These options vest over a four year period, while the restricted stock vests over a five year period.

General

We are a fabless semiconductor company that designs, develops and markets comprehensive platform solutions, including a system-on-chip, firmware and software, for manufacturers of feature-rich, hard disk drive-based and high-capacity flash memory-based personal media players. Personal media players are battery-powered, portable devices to capture, store and play digital media such as audio, photos, and in the future, video. Our platform solutions are designed to enable personal media players to manage thousands of digital media files and allow our customers to build intuitive and customizable user interfaces. Our customers use our platforms to produce high-performance, feature-rich, differentiated personal media players in a cost-effective manner with fast time to market. Our key customers include leading manufacturers such as Inventec Appliances (Shanghai) Co., Ltd. and Inventec Appliances Corp., which are affiliated with each other and which we refer to collectively as Inventec, who manufactures products for Apple Computer Inc. and other companies.

Overview

We were founded in 1999 and introduced our first-generation system-on-chip, or SoC, in 2000. To date, we have introduced five SoC product generations and multiple versions of our firmware and software development kits. Our platforms include an SoC, firmware and software, and we do not sell or recognize revenue on these components separately. We began generating revenue in 2001, and have since increased our revenue from $1.9 million in 2001, to $8.8 million in 2002, $20.9 million in 2003 and $92.6 million in 2004. We recorded revenue of $44.5 million during the three months ended March 31, 2005. We generated net income of $10.4 million in 2004, our first profitable year, and generated net income of $7.8 million during the three months ended March 31, 2005. The net income included non-cash, stock-based compensation charges of $5.8 million in 2004, and $0.4 million during the three months ended March 31, 2005. These charges are described in more detail under “Financial Operations Overview—Stock-Based Compensation.”

We have grown our employee base from six at inception to 194 people as of March 31, 2005 in five countries, with approximately one-half of our employees, primarily engineering staff, located in India. In August 2002 and January 2003, we initiated headcount reductions and restructuring initiatives, which resulted in a reduction in staff of approximately 60 people. The headcount reductions and restructuring initiatives were undertaken to align our corporate spending with a slower than anticipated revenue growth during that timeframe. Specifically, we had originally expected a more rapid adoption of hard disk drive-based personal media players and planned our resources accordingly. Due to a worldwide unfavorable economic environment, including the economic downturn in the United States in 2002 and 2003, consumer demand for hard disk drive-based personal media players did not materialize as we expected during that time. During that period, demand for many semiconductor and consumer electronics products suffered as consumers delayed purchasing decisions or changed or reduced their discretionary spending. We expect that if and when similar

11

Table of Contents

unfavorable economic conditions occur, it could have a similar effect on demand for semiconductor and consumer electronics products in the future and our business could be negatively affected. In addition, if the current economic recovery slows down, we may experience decreases in the demand for our platforms, which may harm our business. Since the headcount reduction, we have increased our staff by 85 employees. We expect that our headcount will increase further to support our expected growth.

Since inception, we have had one major customer, Inventec, an original design manufacturer, or ODM, based in Asia, which manufactures products for Apple and other companies. Inventec continues to be our major customer, accounting for 81.6% of our revenue during the three months ended March 31, 2005. During the most recently completed fiscal quarter we began shipping in volume to an additional customer that manufactures product for Apple. This additional customer represented less than 10% of our revenue during the three months ended March 31, 2005.

In addition to seeking to expand relationships with our existing customers, our strategy is to pursue new customers aggressively and diversify our customer base by focusing on leading global consumer electronics companies and their ODM partners. We intend to continue to focus primarily on customers that produce small form factor, high density storage-based personal media players. To date, our products have primarily been incorporated into hard disk drive-based personal media players. During the first three months of 2005 we introduced the PP5024, our first device that is directed towards high-capacity flash memory-based personal media players. We believe this new product will enable us to now target a larger percentage of the digital media player market. Many of our competitors have offered flash memory-specific products for some time and may have better established products or more expertise with flash-memory-specific solutions.

Some of our customer relationships, other than Inventec, have been developed over a short period of time and are generally in the preliminary stages. We cannot assure you that these customers will generate significant revenue, that we will be able to retain these customers or that we will continue to be successful in attracting new customers. We expect that we will continue to depend upon a relatively limited number of customers for substantially all of our revenue for the foreseeable future.

We market and sell our platforms worldwide through a combination of direct sales personnel, independent sales representatives and distributors. Substantially all of our revenue comes from ODM customers in Asia. A significant amount of the systems designed and manufactured by these customers are then sold to original equipment manufacturers, or OEMs, and consumer electronics companies outside of Asia. Our sales to Asia, including Japan, accounted for approximately 97.9% of our revenue in the three months ended March 31, 2005. We anticipate that a significant amount of our revenue will continue to be generated by sales to customers in that region. All of our sales are denominated in United States dollars.

Because our platforms are designed for use in consumer electronics products, such as personal media players, we expect our business to be subject to seasonality, with increased revenue typically in the third and fourth quarters of each year when customers place orders to meet year-end holiday demand. However, our recent rapid revenue growth makes it difficult for us to assess the impact of seasonal factors on our business.

Our internal forecasting and planning is based in part on customer forecasts we receive. As we are operating in a relatively new industry segment, availability of current market forecasts for high density storage-based personal media players is limited. Because industry practice allows customers to reschedule or cancel orders on relatively short notice, backlog is not a good indicator of our future sales. Cancellations of customer orders or changes in product specifications could result in the loss of anticipated sales without allowing us sufficient time to reduce our inventory and operating expenses.

We outsource to independent third parties the implementation of certain design aspects of our SoCs and all of our manufacturing logistics, including the manufacturing, test, packaging, warehousing and shipping of our SoCs. By outsourcing these functions, we are able to focus more of our financial resources on product design and eliminate the high cost of owning and operating a semiconductor fabrication facility. We also have a logistics warehouse in Hong Kong, which is managed by a local third party, from which location we expect the majority of future shipments to our customers to continue to be made.

Critical Accounting Policies and Estimates

The process of preparing financial statements requires the use of estimates on the part of our management. The estimates used by management are based on our historical experiences combined with management’s understanding of current facts and circumstances. Certain of our accounting policies are considered critical as they are both important to the portrayal of our financial condition and results of operations and require significant or complex judgment on the part of management. For a description of what we believe to be our most critical accounting policies and estimates, refer to our Annual Report on Form 10-K for the year ended December 31, 2004 filed with the Securities and Exchange Commission on March 21, 2005. There have been no changes in any of our critical accounting policies since December 31, 2004.

Table of Contents

Financial Operations Overview

The following describes certain line items in our statements of operations:

Revenue

We generate revenue from sales of our platforms. The main factors that impact our revenue are unit volumes shipped and average selling prices. We have experienced quarter-over-quarter unit volume increases for the past seven quarters while we have seen average selling prices decline over time as our platforms have matured in the market. Overall, we expect average selling prices for our platforms to decline over time as products mature. Our revenue recognition policy is described in more detail under “Critical Accounting Policies and Estimates”, as included in our Form 10-K for the year ended December 31, 2004 filed with the Securities and Exchange Commission on March 21, 2005.

Cost of Revenue

Cost of revenue consists primarily of the cost of finished goods and, to a lesser extent, certain technology license fees, personnel and occupancy associated with manufacturing support, quality assurance and internal inventory handling costs. The cost of finished goods includes the cost for fully packaged and tested semiconductors that we purchase from our manufacturing logistics partners. On occasion, cost of revenue may additionally include a component for write-offs of certain inventories based on forecasted demand in future periods.

Gross Profit and Gross Margin

Gross profit results from deducting cost of revenue from revenue. The gross margin is the percentage derived from dividing gross profit by revenue. Our gross margin each quarter is affected by a number of factors, including product pricing and our product mix, as well as the negotiated price for our finished goods and potential adjustment to our inventory valuation. In the three months ended March 31, 2005, we recorded revenue, and accordingly, gross profit of approximately $0.1 million related to the sale of inventory that had been previously written-off due to changes in customer demand for a older generations of SoC platforms.

Operating Expenses

Research and development expense consists primarily of salaries, bonuses, benefits and related overhead costs for engineering personnel, non-recurring engineering costs, such as prototype wafers and mask sets, costs of outside engineering services from contractors and consultants and depreciation of engineering equipment. Before releasing new products, we incur charges for prototype wafers and mask set revisions, which can cause a fluctuation in research and development expense. Some of our development costs have been offset by amounts we receive from our customers on non-recurring engineering services arrangements where we are reimbursed for a portion of our engineering costs. Typically, these services are for the development of customized product designs for customers during the early pre-production stage. The costs of these development projects are expensed as incurred and the reimbursement is recognized when the development is accepted by the customer. The reimbursements against research and development expense on these research activities were approximately $0.1 million and $0.2 million in the first three months of 2005 and 2004, respectively. In the future, we do not expect reimbursements from engineering services to be significant. We expect our research and development expense to increase in absolute dollars as we continue to invest to develop new products to be competitive in the future.

Selling, general and administrative expense consists primarily of salaries, bonuses, benefits and related overhead costs for sales, marketing and administrative personnel, legal and accounting services as well as marketing activities. We expect selling, general and administrative expense to increase in absolute dollars as we expand our sales and marketing efforts, hire additional personnel and incur other costs related to the anticipated growth of our business, our operations as a public company and improvements to our information technology infrastructure.

Stock-Based Compensation

Stock-based compensation includes two components, the amortization of deferred stock compensation and variable stock-based compensation. Deferred stock compensation results from the grant of stock options at exercise prices less than the deemed fair value of the underlying common stock on the grant date for directors, officers and employees. Variable stock-based compensation equals the fair value of stock options, preferred stock and warrants granted to consultants.

Variable stock-based compensation results from the difference between the fair value of the stock award and the price at which the instrument can be exercised. We have recorded variable stock-based compensation related to option awards to a director and four non-employee advisory consultants, as well as a note to a stockholder, who is also a director, for consulting services. Although most of such instruments have vested or have been terminated, we expect to incur variable stock-based compensation from some of these instruments in future periods. We report employee stock-based compensation as a separate expense rather than including it in the functional category to which it relates, as we believe it provides more meaningful comparison.

13

Table of Contents

Interest and Other Income (Expense), Net

Interest and other income (expense), net consists mostly of interest earned on our cash and investments, offset by interest expense associated with our bank borrowings.

Provision for Income Taxes

We recognize deferred assets and liabilities on differences between the book and tax basis of assets and liabilities using current effective rates. Further, deferred tax assets are recognized for the expected realization of available net operating loss carryforwards. A valuation allowance is recorded to reduce a deferred tax asset to an amount that we expect to realize in the future. We continually review the adequacy of the valuation allowance and recognize these benefits if a reassessment indicates that it is more likely than not that these benefits will be realized. In addition, we continuously evaluate our tax contingencies and recognize a liability when we believe that it is probable that a liability exists. Accordingly, our use of the net operating loss carryforwards and credit carryforwards is limited by the annual limitations described in Sections 382 and 383.

Results of Operations

The following table sets forth, for the periods indicated, the percentage of revenue represented by selected items from our consolidated statements of operations.

Three Months Ended March 31, 2005 and 2004

Revenue . Revenue increased from $10.2 million in the three months ended March 31, 2004 to $44.5 million in the three months ended March 31, 2005, a 336% increase. This increase was primarily due to an approximately 374% increase in unit shipments of our platforms, partially offset by an approximately 8% decline in our overall average selling prices as certain products matured. We expect the trend of declining average selling prices for existing products to continue as these products mature further in the market, although we expect to sell new products with enhanced features at relatively higher prices initially. Overall, however, we expect the average selling prices for our products in aggregate to decline over time, which may have a negative impact on our future margins if we cannot reduce our associated costs accordingly. Our increased sales volumes were primarily due to the continued growth of the hard disk drive-based personal media player market and the introduction of our PP5022 product into the market at the end of 2004. Revenue on sales to the Asia/Pacific region, including Japan, was 97.9 % and 99.2% in the three months ended March 31, 2005 and 2004, respectively. Sales to Inventec, our only customer that accounted for more than 10% of our revenue in the three months ended March 31, 2005, accounted for 81.6% of our revenue in the three months ended March 31, 2005 compared to 92.3% of our revenue in the three months ended March 31, 2004. Inventec, and another customer of ours manufacture product for Apple Computer Inc.

Cost of revenue and gross margin . Cost of revenue increased from $6.6 million in three months ended March 31, 2004 to $25.3 million in the three months ended March 31, 2005, a 283% increase. This increase was primarily due to an increase in unit shipments of our platforms and the associated costs to produce and support these higher unit volumes, partially offset by an approximately 20% decline in our average unit cost as we were able to negotiate more favorable pricing from our manufacturing logistics partners.

Gross margin was 35.4% in the three months ended March 31, 2004 and 43.1% in the three months ended March 31, 2005. We recognized revenue of approximately $0.1 million in the three months ended March 31, 2005 on the sale of previously written-off older-generation inventory. Gross margin in the first three months of 2004 was negatively impacted by approximately $0.4 million of costs incurred to conform a product platform to the specifications of our principal customer, and an additional $0.3 million to expedite manufacture of this platform to this customer. We did not have any similar expenses during the first three months of 2005. We expect

15

Table of Contents

that we may need to record adjustments to our inventory valuation from time to time and that our gross margin may fluctuate as we introduce new platforms and products and as the market for our platforms becomes more competitive. We expect that future sales, if any, of our current balance of written-off inventory would not have a material impact on our future gross profits.

Research and development . Research and development expense, not including stock-based compensation, increased from $2.6 million in the three months ended March 31, 2004 to $6.4 million in the three months ended March 31, 2005, a 146% increase. Approximately $1.6 million of the increase was due to an increase in personnel-related expenses resulting from a 53% increase in research and development headcount at March 31, 2005 as compared to March 31, 2004. In addition, approximately $1.8 million of the increase in research and development expenses was due to an increase in engineering-related expenses, including non-recurring engineering charges paid to our vendors, as well as license fees for certain technologies that we may incorporate into our future products. Most of our engineering expenses related to design work on future product generations as well as supporting hardware and software modifications on our current product. We expect to continually increase our spending for the development of future product generations in the remainder of 2005.

Selling, general and administrative . Selling, general and administrative expense, not including stock-based compensation, increased from $1.4 million in the three months ended March 31, 2004 to $2.9 million in the three months ended March 31, 2005, a 107% increase. The increase of approximately $1.5 million was primarily due to an increase of $0.4 million in personnel-related expenses, resulting from a 42% increase in selling, general and administrative headcount at March 31, 2005 as compared to March 31, 2004, an increase of $0.1 million in travel-related and other expenses including dues and subscriptions, and other costs related to our being a publicly-held company. We additionally had an increase of approximately $0.8 million in professional services-related expenses, including accounting and legal expenses, as well as an increase of $0.1 million related to our corporate insurance premiums.

Stock-based compensation . Stock-based compensation expense decreased from $2.0 million in three months ended March 31, 2004 to $0.4 million in three months ended March 31, 2005. The majority of stock-based compensation recorded in the three months ended March 31, 2005 related to the amortization of deferred stock-based compensation for employee stock options grants, as the fair value of our common stock increased during the twelve months prior to our initial public offering in November 2004. Of the $2.0 million of expense incurred during the three months ended March 31, 2004, $1.1 million was related to a non-recourse promissory note issued by a director in exchange for his consulting services to us, an additional $0.6 million associated with 133,333 options granted to a director in connection with his management services to us, $0.2 million associated with a common stock warrant offered to our chief executive officer in connection with a bonus award, and $0.1 million related to the amortization of deferred stock compensation. As of March 31, 2005, we had approximately $4.4 million of deferred stock compensation. We are amortizing deferred stock compensation on a straight-line basis through 2008. We currently expect to incur amortization of deferred stock-based compensation of approximately $1.4 million in 2005, 2006 and 2007, respectively, and $0.6 million in 2008.

Interest and other income (expense), net . Interest and other income, net, increased from $12,000 during the three-month period ended March 31, 2004 to $0.9 million during the three-month period ended March 31, 2005. This increase was primarily due to an increase in interest income related to our significantly increased balance of cash, cash equivalents and short-term investments.

Provision for income taxes . During the three-month period ended March 31, 2005 we recorded a provision for income taxes using an effective tax rate of 25%, or approximately $2.6 million. We did not record a provision for income tax during the first three-month period in 2004 as the Company was not profitable during that period. The provision for income taxes recorded in the three-month period ended March 31, 2005 differs from the amount computed by applying the statutory U.S. federal rate principally due to our utilization of net operating loss carryforwards and certain research and development related tax credits.

Liquidity and Capital Resources

We have historically financed our operations primarily through sales of equity securities and, to a lesser extent, through our bank borrowings. Additionally, during our fiscal year 2004 we generated $3.2 million in cash from our operating activities, and in the three months ended March 31, 2004 we generated $14.8 million of cash from our operating activities. Through March 31, 2005, we raised approximately $195.9 million through equity financings, which includes approximately $111.0 million, net of fees and cash paid for expenses, raised from the initial public offering of our common stock in November 2004. As of March 31, 2005, we had approximately $137.2 million in cash, cash equivalents, and investments. We outsource our design implementation and all of our manufacturing logistics, semiconductor fabrication, assembly and test. By outsourcing these functions, we are able to focus more of our financial resources on product design and eliminate the high fixed cost of owning and operating a semiconductor fabrication facility.

Operating Activities

Net cash used in operating activities was $1.0 million in the three months ended March 31, 2004, while net cash provided by operating activities was $14.8 million in the three months ended March 31, 2005. In the three months ended March 31, 2004, net cash

16

Table of Contents

used in operating activities resulted from our losses and the growth in accounts receivable and inventory driven by higher sales. In the three months ended March 31, 2005, net cash generated by operating activities resulted primarily from net income and the increases in accounts payable, accrued liabilities and income tax payable, which more than offset the growth in accounts receivable and inventory. The increase in accounts payable and other accrued liabilities during the three months ended March 31, 2005 was mainly due to non-recurring engineering-related expenses incurred but not paid as of the end of the period, as well as a significantly higher amount of payables due to the timing of inventory receipts and their related payments to our inventory vendors compared to the prior period.

Investing Activities

Capital expenditures were approximately $0.2 million and $0.5 million in the three months ended March 31, 2004 and 2005, respectively. These expenditures were primarily for the purchase of computer equipment and development tools and test equipment for engineering development. We anticipate an increase in our capital expenditures consistent with our anticipated growth. Net cash used in investing activities also consisted of the purchase of $31.7 million of short-term marketable securities in the three months ended March 31, 2005, with no similar purchases in the same period last year.

Financing Activities

Net cash used in financing activities was $0.2 million in the three months ended March 31, 2004, while net cash used in financing activities was $0.5 million in the three months ended March 31, 2005. Financing activities included sales from the issuance of our common stock and convertible preferred stock, borrowings and repayments against our bank borrowings, and the exercise of options to purchase our common stock. In the three months ended March 31, 2004, we repaid $0.8 million against our bank borrowings. In the three months ended March 31, 2005, cash paid for expenses related to our November 2004 initial public offering costs were approximately $0.5 million.

As of March 31, 2005, we did not have any amounts outstanding against a total of $15.0 million of bank borrowings available. We have a revolving bank line of credit, which bears interest at the bank’s prime interest rate plus 0.75%, but not less than 4.75% and expires in November 2005.

We expect to experience growth in our operating expenses, including our research and development, sales and marketing and general and administrative expenses in the foreseeable future in order to execute our business strategy. We intend to fund these activities with cash generated from operations. This increase in operating expenses may not result in an increase in our revenue and our anticipated revenue may not be sufficient to support these increased expenditures. We anticipate that operating expenses, working capital as well as planned capital expenditures will constitute a material use of our cash resources.

We believe that our current cash balance and cash generated from operations, along with our available line of credit, will be sufficient to meet our working capital and capital expenditure requirements for at least the next 12 to 24 months. If we require additional capital resources to grow our business internally or to acquire complementary technologies and businesses at any time in the future, we may seek to sell additional equity or debt securities or obtain other debt financing. The sale of additional equity or convertible debt securities could result in more dilution to our stockholders. Financing arrangements may not be available to us, or may not be available in amounts or on terms acceptable to us.

Factors That May Affect Our Operating Results

In evaluating PortalPlayer, Inc. and our business, you should carefully consider the following factors in addition to the other information in this quarterly report on Form 10-Q. Any one of the following risks could seriously harm our business, financial condition, and operating results, causing the price of our stock to decline. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also impair our business operations.

We currently depend on one customer for a high percentage of our revenue and the loss of, or a significant reduction in orders from, this customer would significantly reduce our revenue and adversely impact our operating results.

Inventec Appliances (Shanghai) Co., Ltd. and Inventec Appliances Corp., which are affiliated with each other and which we refer to collectively as Inventec, accounted for approximately 81.6% of our revenue during the three months ended March 31, 2005, and 89.3% of revenue in our fiscal year 2004. The loss of sales to Inventec would have a significant negative impact on our business. Because our sales to this customer are made pursuant to standard purchase orders rather than contracts, orders may be cancelled or reduced more readily than if we had long-term purchase commitments with this customer. Although we believe that cancellations to date have been insignificant, purchase orders can be cancelled or rescheduled on relatively short notice. Cancellations of customer orders could result in the loss of anticipated sales without allowing us sufficient time to reduce our inventory and operating expenses. In addition, changes in forecasts or the timing of orders from this customer expose us to the risks of inventory shortages or excess inventory, particularly during end product transitions that require a new generation of our platforms. This in turn could cause our operating results to fluctuate. For example, we experienced a lower than expected number of orders from Inventec in the first quarter of 2003, which contributed to a significant temporary decrease in our revenue.

17

Table of Contents

We believe that nearly all of our platforms sold to Inventec are incorporated in the Apple iPod product family. Apple may choose to use platforms in addition to ours for its products, use a different platform than ours altogether or develop an in-house solution. Any of these events would significantly harm our business. Further, because such a large portion of our revenue is tied to the Apple iPod, our success depends on Apple’s continued success with these products.

In addition, if Inventec’s relationship with Apple is disrupted for inability to deliver sufficient products or for any other reason, it could have a significant negative impact on our business. We do not know the terms of Inventec’s business relationship with Apple. Apple may choose to work with other original design manufacturers. For example, during the most recently completed fiscal quarter we began shipping in volume to an additional customer that manufactures product for Apple. This additional customer represented less than 10% of our revenue during the three months ended March 31, 2005. The loss by Inventec or this other customer of sales to Apple could also harm our business and financial position.

There are a relatively small number of potential customers for our platforms and we expect this customer concentration to continue for the foreseeable future. Therefore, our operating results will likely continue to depend on sales to a relatively small number of customers, as well as the ability of these customers to sell products that incorporate our platforms. In addition, we may from time to time enter into customer agreements providing for exclusivity periods during which we may only sell a specified product to that customer. Except for Inventec, our customer relationships have been developed over a short period of time and are generally in their preliminary stages. We cannot be certain that these customers will generate significant revenue in the future. If our relationships with our newer customers do not continue to develop, we may not be able to expand our customer base or maintain or increase our revenue.

We depend on one product family for all of our revenue, and if sales of our platforms decline, our business and financial position will suffer.

We have one product family, which currently consists of platforms primarily for hard disk drive-based personal media players. Our platforms consist of a system-on-chip, firmware and software. We currently derive, and expect to continue to derive in the near term, all of our revenue from sales of our platforms. Continued market acceptance of our platforms is critical to our future success. Because we have only one product family, we do not have alternate sources of revenue if sales of our platforms decline.

Our quarterly revenue and operating results are difficult to predict, and if we do not meet quarterly financial expectations, our stock price will likely decline.

Our quarterly revenue and operating results are difficult to predict and have in the past, and may in the future, fluctuate from quarter to quarter. It is possible that our operating results in some quarters will be below market expectations. This would likely cause the market price of our common stock to decline. Our quarterly operating results are affected by a number of factors, including:

18

Table of Contents

We base our planned operating expenses in part on our expectations of future revenue, and a significant portion of our expenses is relatively fixed in the short term. As we are operating in a new industry segment, we have limited historical financial data from which to predict future sales for our platforms. As a result, it is difficult for us to forecast our future revenue and budget our operating expenses accordingly. Our operating results would be adversely affected to the extent customer orders are cancelled or rescheduled. If revenue for a particular quarter is lower than we expect, we likely will be unable to proportionately reduce our operating expenses for that quarter, which would harm our operating results for that quarter.

We have incurred significant losses since inception and may incur losses in the future. We may not be able to generate sufficient revenue in the future to sustain profitability.

We have incurred significant net losses since inception and, at March 31, 2005, we had an accumulated deficit of approximately $54.4 million. Although we have recently achieved profitability, we cannot be certain that we will sustain profitability in the future. To sustain profitability, we will need to generate and grow our revenue to support an increase in expense levels. We may not be able to sustain or increase profitability on a quarterly or an annual basis. If we do not sustain profitability or otherwise meet the expectations of securities analysts or investors, the market price of our common stock will likely decline.

If we are unable to develop successful new platforms or other products to keep pace with rapid technological change, we will be unable to expand our business and our operating results and competitive position would be harmed.

The consumer electronics market is characterized by rapidly changing technology requiring improved features, such as lower power or smaller size. This requires us to continuously develop new platforms or other products and enhancements for existing platforms to keep pace with evolving industry standards and rapidly changing customer requirements. We may not have the financial resources necessary to fund future innovations. Even if we have sufficient financial resources to fund future innovations, if our future innovations produce technology that is behind that of our competitors, we may lose customers. Similarly, if our future innovations are ahead of the then-current technological standards in our industry, customers may be unwilling to purchase our platforms until the consumer electronics market is ready to accept them. If we are unable to successfully define, develop and introduce competitive new platforms or other products and enhance existing platforms, we may not be able to compete successfully. In addition, if we, or our customers, are unable to manage product transitions, our business and results of operations would be negatively affected.

Development of new platforms and products may require us to obtain rights to use intellectual property that we currently do not have. If we are unable to obtain or license the necessary intellectual property on reasonable terms or at all, our product development may be delayed and the gross margins on our planned products may be less than anticipated, and our business and results of operations would be negatively affected.

Because the markets in which we compete are highly competitive and many of our competitors have greater resources than us, we may not be able to compete successfully and we may lose or be unable to gain market share.

We face competition from a large number of competitors, including Freescale Semiconductor, Intel, Philips Semiconductor, Samsung Semiconductor, SigmaTel, Telechips and Texas Instruments. We expect to face increased competition in the future. In particular, we face competition from semiconductor companies which have traditionally focused on flash-based players. We may also face competition from some of our customers who have developed products or technologies internally which are competitive with our platforms, or who may enter into strategic relationships with or acquire existing semiconductor providers.

In addition, the consumer electronics market, which is the principal end-market for our platforms, has historically been subject to intense price competition. In many cases, low-cost, high-volume producers have entered this market and driven down gross margins. If a low-cost, high-volume producer should develop products that are competitive with our platforms, our sales and gross margins would suffer.

Many of our current and potential competitors have longer operating histories, greater name recognition, access to larger customer bases and significantly greater financial, sales and marketing, manufacturing, distribution, technical and other resources than us. As a result, they may be able to respond more quickly to changing customer demands or to devote greater resources to the development, promotion and sales of their products than we can. Our potential competitors may develop and introduce new products that have lower prices, provide superior performance, provide greater processing power or achieve greater market acceptance than our platforms. In addition, in the event of a manufacturing capacity shortage, these competitors may be able to obtain capacity when we are unable to do so. Our competitors may also be able to provide greater incentives to customers through rebates and marketing development funds and similar programs. It is possible that new competitors or alliances among existing competitors could emerge and rapidly acquire significant market share, which would harm our business. Some of our competitors with multiple product lines

19

may bundle their products to offer a broader product portfolio or integrate processing capacity similar to or greater than ours into other products that we do not sell, which may make it difficult for us to gain or maintain market share. If we fail to compete successfully, our business would suffer and we may lose or be unable to gain market share.

We believe that nearly all of our platforms sold to Inventec are incorporated in the Apple iPod product family. As a result, our business is also affected by competition in the market for hard disk drive-based personal media players. If competing products that are not based on our platform solution it could harm our business and cause our revenue to decline.

If we fail to adequately forecast demand for our platforms, we may incur product shortages or excess product inventory.

Most of our revenue is derived from customers who require us to be able to provide product in excess of existing orders on relatively short notice. If these customers do not order more of our platforms than they forecast, then we could have excess inventory if we do not have other purchasers for this inventory. In this instance, we would be required to write-off excess inventory in accordance with our inventory policy. On the other hand, if we are unable to supply platforms at the levels required by our major customer, they are entitled to seek alternative supply arrangements to meet their needs. In the event of a supply shortage, we may be unable to meet the demands of our other customers. Any of these events could harm our operating results and our business.

We may place binding manufacturing orders with our manufacturing logistics partners in advance of receiving purchase orders from our customers. Changes in forecasts or timing of orders expose us to risks of inventory shortages or excess product inventory, particularly during end-product transitions. Obtaining additional supply in the face of increased demand or supply shortages may be costly or impossible, particularly in the short-term, which could prevent us from fulfilling orders. As a result, an incorrect forecast may result in substantial inventory that is aged and obsolete, which could result in write-downs of excess, aged or obsolete inventory. In addition, our platforms have rapidly declining average selling prices. Therefore, our failure to adequately estimate demand for our platforms could cause our quarterly operating results to fluctuate and cause our stock price to decline.

Because of the lengthy sales cycles for our platforms and the relatively fixed nature of a significant portion of our expenses, we may incur substantial expenses before we earn associated revenue and may not ultimately achieve our forecasted sales for our platforms.

Our sales cycles from design to manufacture of our platforms can typically take nine to 12 months. Sales cycles for our platforms are lengthy for a number of reasons, including:

As a result of our lengthy sales cycles, we may incur substantial expenses before we earn associated revenue because a significant portion of our operating expenses is relatively fixed and based on expected revenue. If customer cancellations or product changes occur, this could result in the loss of anticipated sales without allowing us sufficient time to reduce our operating expenses.

We are subject to the risk of supply problems with other components of the end products of our customers and if our customers cannot obtain sufficient supplies of these components, sales of our platforms could suffer.

In addition to our platforms, the end products of our customers that are sold to consumers also incorporate other components outside of our control, such as hard disk drives. If our customers cannot obtain sufficient supplies of these or other components, sales of our platforms could suffer because our customers may purchase fewer platforms from us than they would have otherwise purchased. For example, small form factor hard disk drive supply was constrained during 2003 and 2004. We believe that this supply constraint may have caused our customers to purchase fewer platforms than they might otherwise have purchased, thus negatively impacting our revenue. Although we cannot estimate the impact on our revenue from these supply constraints, we believe that future supply problems with the other components of the end products of our customers, including small form factor hard disk drives, may negatively impact our business and revenue in the future. As a result, demand for our platforms depends on the availability of other components that we do not control.

Table of Contents

We depend on third-party service providers to implement certain aspects of the design of our semiconductors, and to manage our foundry, test, packaging, warehouse and shipping relationships.

We rely on two third-party service providers, eSilicon Corporation, or eSilicon, and LSI Logic Corporation, or LSI Logic, to implement certain aspects of the design of our semiconductors, and to manage the manufacture, test, packaging, warehousing and shipping of our semiconductors. eSilicon and LSI Logic either provide these services directly or engage and manage other parties to provide them. As a result, we have significantly less control over certain aspects of the design and manufacture of our semiconductors and do not directly control our product delivery schedules, assembly and testing costs or quality assurance and control. We do not have long-term agreements with eSilicon or LSI Logic. We typically procure services from these suppliers on a purchase order basis. If the operations of eSilicon or LSI Logic were disrupted or their financial stability impaired, if eSilicon or LSI Logic were unable to properly manage the service providers that they retain for us or if they should choose not to devote capacity to our semiconductors in a timely manner, our business would suffer as we would be unable to produce finished platforms on a timely basis.

Because we use manufacturing logistics partners who in turn use independent foundries and subcontractors to manufacture, assemble and test our semiconductors, we may face risks such as insufficient allocation of assembly and test capacity and limited control over the associated costs and semiconductor output, or yield. Damages to third-party facilities caused by natural or man-made disasters could result in the loss of production material and a temporary disruption in the flow of material.

In addition, the cyclicality of the semiconductor industry has periodically resulted in shortages of manufacturing assembly and test capacity and other disruptions of supply. We may not be able to find sufficient suppliers at a reasonable price or at all if these disruptions occur. If we do not manage these risks adequately, our business and results of operations would be harmed.

Independent foundries manufacture the semiconductors used in our platforms, and any failure to obtain sufficient foundry capacity could significantly delay our ability to ship our platforms and damage our customer relationships.

We do not own or operate a semiconductor fabrication facility. Instead, we rely on third parties to manufacture our semiconductors. Through our relationships with eSilicon and LSI Logic, three outside foundries, LSI Logic in the United States, Taiwan Semiconductor Manufacturing Company, or TSMC, in Taiwan, and United Microelectronics Corporation, or UMC, in Taiwan, currently manufacture all of our semiconductors, and no single foundry manufactures more than one model of our semiconductors. As a result, we face several significant risks, including:

The ability of each foundry to provide us with semiconductors is limited by its available capacity. Our manufacturing logistics partners do not have a guaranteed level of production capacity with either of these foundries and it is difficult to accurately forecast our capacity needs. In addition, our manufacturing logistics partners do not have long-term agreements with any of these foundries and place orders on a purchase order basis. We place our orders on the basis of our customers’ purchase orders and sales forecasts; however, the foundries can allocate capacity to the production of other companies’ products and reduce deliveries to our manufacturing logistics partners on short notice. It is possible that foundry customers that are larger and better financed than our manufacturing logistics partners, or that have long-term agreements with these foundries, may induce these foundries to reallocate capacity to them. Any reallocation could impair our ability to secure the supply of semiconductors that we need for our platforms. In addition, interruptions to the wafer manufacturing processes caused by a natural or man-made disaster could result in partial or complete disruption in supply until we or our manufacturing logistics partners are able to shift manufacturing to another fabrication facility. It may not be possible to obtain sufficient capacity or comparable production costs at another foundry. We might at any time decide to migrate our design methodology to a new third-party foundry which could result in increased costs, resources and development time comparable to a new product development effort. Any reduction in the supply of semiconductors for our platforms could significantly delay our ability to ship our platforms and potentially damage our relationships with existing customers.

If the foundries that manufacture our semiconductors do not achieve satisfactory yields or quality, our sales could decrease and our relationships with our customers and our reputation may be harmed.

The manufacture of semiconductors is a highly complex process. Minor deviations in the manufacturing process can cause substantial decreases in yield and in some cases, cause production to be suspended or yield no output. The foundries that manufacture our semiconductors have from time to time experienced lower than anticipated manufacturing yields, including yields for our semiconductors. This often occurs during the production of new products or architectures or the installation and start-up of new process technologies or equipment. We may also experience yield problems as we migrate our manufacturing processes to smaller geometries. If the foundries that manufacture our semiconductors do not achieve planned yields, our product costs could increase, and product availability would decrease. Although to date we have not experienced unsatisfactory yields that have had a significant negative impact on our business, we believe we may face risks of unsatisfactory yields in the future.

21

Table of Contents

Our semiconductors are qualified with the foundries that manufacture our semiconductors, at which time a minimum acceptable yield is established. If actual yield is below the minimum, the foundry or our manufacturing logistics partner incurs the cost of the wafers. If actual yield is above the minimum, we incur the cost of the wafers. The manufacturing yields for our new platforms tend to be lower initially. Our platform pricing is based on the assumption that an increase in manufacturing yields will continue, even with the increasing complexity of our semiconductors. Short product life cycles require us to quickly develop new platforms and to manufacture these platforms for short periods of time. In many cases, these short product life cycles will not lead to the higher manufacturing yields and declining costs typically associated with longer, high-volume manufacturing periods. As a result, if our foundries fail to deliver fabricated silicon wafers of satisfactory quality in the volume and at the price required, we will be unable to meet our customers’ demand for our platforms or to sell those platforms at an acceptable profit margin, which would adversely affect our sales and margins and damage our customer relationships.

The facilities of the independent foundries upon which we rely to manufacture our semiconductors are located in regions that are subject to earthquakes and other natural disasters, as well as geopolitical risk and social upheaval.

The outside foundries and their subcontractors upon which we rely to manufacture all of our semiconductors are located in countries that are subject to earthquakes and other natural disasters, as well as geopolitical risk and social upheaval. Three foundries, LSI Logic in the United States and TSMC and UMC, both in Taiwan, currently manufacture substantially all of our semiconductors. Any earthquake or other natural disaster in these countries could materially disrupt these foundries’ production capabilities and could result in our experiencing a significant delay in delivery, or substantial shortage, of our platforms. In addition, some of these facilities are subject to risks associated with uncertain political, economic and other conditions in Asia, such as political turmoil in the region and the outbreak of severe acute respiratory syndrome, or SARS, which could disrupt the operation of these foundries and in turn harm our business. Increased instability in these regions may also negatively impact the desire of our employees and customers to travel and the reliability and cost of transportation, thus harming our business.

Defects in our platforms could result in a decrease in customers and revenue, unexpected expenses and loss of market share.

Our platforms are complex and must meet stringent quality requirements. Products as complex as ours may contain undetected hardware or software errors or defects, especially when first introduced or when new versions are released. For example, our platforms may contain errors that are not detected until after they are shipped because we cannot test for all possible scenarios. These errors could cause us to incur significant re-engineering costs, divert the attention of our engineering personnel from product development efforts and significantly affect our customer relations and business reputation. If we deliver platforms with errors, defects or bugs, our credibility and the market acceptance and sales of our platforms could be harmed. Defects could also trigger warranty obligations and lead to product liability as a result of lawsuits against us or against our customers. We have agreed to indemnify our customers in some circumstances against liability from defects in our platforms. A successful product liability claim against us could require us to make significant damage payments, which would negatively affect our financial results. In addition, we might incur additional costs to meet the specifications of our customers. For example, in the first quarter of 2004, we incurred additional testing costs to conform our platform to the specifications of our principal customer.

We may not obtain sufficient patent protection, which could harm our competitive position and increase our expenses.

Our success and ability to compete depends to a significant degree upon the protection of our proprietary technology. As of March 31, 2005, in the United States we had six issued patents and 10 patent applications pending. Our patent applications may not result in issued patents, and we cannot be certain that any issued patents will not be challenged, invalidated or declared unenforceable. Furthermore, any patents issued may provide only limited protection for our technology and the rights that may be granted under any future patents may not provide competitive advantages to us. For example, competitors could successfully challenge any issued patents or, alternatively, could develop similar technologies on their own or design around our patents. Also, patent protection in foreign countries may be limited or unavailable in areas where we would like to obtain this protection. It may be difficult for us to protect our intellectual property from misuse or infringement by other companies in these countries. For example, if our manufacturing logistics partners or the foundries which manufacture our semiconductors lose control of our intellectual property, it would be more difficult for us to take remedial measures because some of our foundries are located in countries that do not have the same protection for intellectual property that is provided in the United States. Our inability to enforce our intellectual property rights in some countries may harm our business.

22

Table of Contents

We also rely upon trademark, copyright and trade secret laws and contractual restrictions to protect our proprietary rights, and, if these rights are not sufficiently protected, our ability to compete and generate revenue could suffer.

We also rely on a combination of trademark, copyright and trade secret laws, and contractual restrictions, such as confidentiality agreements and licenses, to establish and protect our proprietary rights. We seek to protect our source and object codes for our software, and design code for our platforms, documentation and other written materials under trade secret and copyright laws. We also typically require employees and consultants with access to our proprietary information to execute confidentiality agreements. The steps taken by us to protect our proprietary information may not be adequate to prevent misappropriation of our technology. In addition, our proprietary rights may not be adequately protected because:

The laws of other countries in which we market our platforms, such as some countries in the Asia/Pacific region, may offer little or no protection for our proprietary technologies. Reverse engineering, unauthorized copying or other misappropriation of our proprietary technologies could enable third parties to benefit from our technologies without paying us for doing so. Any inability to adequately protect our proprietary rights could harm our ability to compete, generate revenue and to grow our business.

Our intellectual property indemnification practices may adversely impact our business.

We may be required to indemnify our customers and our third-party intellectual property providers for certain costs and damages of patent infringement in circumstances where our platforms are a factor creating the customer’s or these third-party providers’ infringement exposure. This practice may subject us to significant indemnification claims by our customers and our third-party providers. In some instances, our platforms are designed for use in devices manufactured by our customers that comply with international standards, such as the MP3 compression standard. These international standards are often covered by patent rights held by third parties, which may include our competitors. The combined costs of identifying and obtaining licenses from all holders of patent rights essential to such international standards could be high and could reduce our profitability or increase our losses. The cost of not obtaining these licenses could also be high if a holder of the patent rights brings a claim for patent infringement. We are aware that some of our customers have received a notice from a third party seeking to grant a royalty bearing patent license to those customers and claiming that those customers’ manufacture and sale of products capable of decoding MP3 files violates patents which the third party has the right to enforce. In the contracts under which we distribute MP3 decoding products, we generally have agreed to indemnify our customers with respect to patent claims related to MP3 decoding technology. At least one of our key customers has requested indemnification relating to notices received from this third party. We cannot assure you that additional claims for indemnification will not be made or that these claims would not harm our business, operating results or financial condition.

We may face intellectual property infringement claims that could be time-consuming and costly to defend and could result in our loss of significant rights.

From time to time, we and our customers receive letters, including letters from various industry participants, alleging infringement of patents. Although we are not currently aware of any parties pursuing or intending to pursue infringement claims against us, we cannot assure you that we will not be subject to such claims in the future. In some cases, a company can avoid or settle litigation on favorable terms because it possesses patents that can be asserted against or licensed to the plaintiff. Since we currently hold only six patents, we would not be in a favorable bargaining position in these situations. Our third-party suppliers may also become subject to infringement claims, which in turn could negatively impact our business. We may also initiate claims to defend our intellectual property. Intellectual property litigation is expensive and time-consuming and could divert management’s attention from our business and could have a material adverse effect on our business, operating results or financial condition. If there is a successful claim of infringement against us, our customers or our third-party intellectual property providers, we may be required to pay substantial damages to the party claiming infringement, develop non-infringing technology, stop selling products or using technology that contains the allegedly infringing intellectual property or enter into royalty or license agreements that may not be available on acceptable terms, if at all. Our failure to develop non-infringing technologies or license the proprietary rights on a timely basis could harm our business. Also, we may be unaware of pending patent applications that relate to our platforms. Parties making infringement claims may be able to obtain an injunction, which could prevent us from selling our platforms or using technology that contains the allegedly infringing intellectual property which could have a material negative effect on our business. Parties making infringement claims may also be able to bring an action before the International Trade Commission that could result in an order stopping the importation into the United States of our platforms.

Our platforms incorporate third-party technology and if we were unable to continue to use this technology, our business could suffer.

We incorporate into our platforms third-party technology which we obtain pursuant to license agreements. We rely on third-party technology in our platforms and there may not be suitable alternate sources for this technology if we were to lose rights to use this technology. If these license agreements were terminated by the third parties or we otherwise lost rights to use this technology, this termination or loss could materially harm our business.

We have significant international activities and customers, and plan to continue these efforts, which subject us to additional business risks, including logistical complexity, political instability and currency fluctuations.

Our sales to the Asia/Pacific region, including Japan, accounted for approximately 97.9% of our revenue during the three months ended March 31, 2005, and 99.8% of our revenue in our fiscal year 2004. We anticipate that a significant amount of our revenue will continue to be represented by sales to customers in that region. A large percentage of our sales outside the United States are made to original design manufacturer customers in Asia, who may ultimately sell their products to original equipment manufacturers outside of Asia. We also maintain an engineering facility in India, where we conduct a significant portion of our engineering activities, and may expand our international operations, such as in Asia. Increased instability in the Asia/Pacific region may adversely impact the desire of our employees and customers to travel, as well as the reliability and cost of transportation, which in turn would harm our business. Risks we face in conducting business internationally include:

Specifically, in the Asia/Pacific region, we face risks associated with a recurrence of SARS, tensions between countries in that region, such as political tensions between China and Taiwan and the ongoing discussions with North Korea regarding its nuclear weapons program, potentially reduced protection for intellectual property rights, government-fixed foreign exchange rates, relatively uncertain legal systems and developing telecommunications infrastructures. In addition, some countries in this region, such as China, have adopted laws, regulations and policies which impose additional restrictions on the ability of foreign companies to conduct business in that country or otherwise place them at a competitive disadvantage in relation to domestic companies.

To date, all of our sales to international customers and purchases of components from international suppliers have been denominated in U.S. dollars. As a result, an increase in the value of the U.S. dollar relative to foreign currencies could make our platforms more expensive for our international customers, thus potentially leading to a reduction in our sales and profitability. Furthermore, many of our competitors are foreign companies that could benefit from such a currency fluctuation, making it more difficult for us to compete with those companies. To date, we have not experienced any significant reductions in sales and profitability as a result of foreign currency fluctuations. However, we believe that we may have increased risks associated with such currency fluctuations in the future.

Our business will suffer if we cannot meet increases in demand due to seasonality.

Because our platforms are designed for use in consumer electronic products, such as personal media players, our business is subject to seasonality, with increased revenue typically in the third and fourth quarters of each year, when customers place orders to meet year-end holiday demand, and lower revenue in the first and second quarters of each year. However, our recent revenue growth makes it difficult for us to accurately assess the impact of seasonal factors on our business. If we or our customers are unable to ramp up production of new or existing products to meet any increases in demand due to seasonality or other factors, our sales and operating results would suffer.

The average selling prices of our platforms have historically decreased and will likely do so in the future, which could harm our revenue and gross profits.

The average selling price of consumer electronics products historically have declined significantly over a product’s life. As a result, in the past, we have reduced the average selling prices of our platforms in anticipation of future competitive pricing pressures, new product introductions by us or our competitors and other factors. We expect that we will have to similarly reduce prices in the future for mature products. In addition, a reduction in our average selling prices to one or more customers could also impact our average selling prices to other customers. A decline in overall average selling prices would harm our gross margins. Our financial results will suffer if we are unable to offset any reductions in our average selling prices by increasing our sales volumes, reducing our costs, adding new features to our existing platforms or developing new or enhanced platforms or products on a timely basis with higher selling prices or gross margins.

We do not expect to sustain our recent growth rate, and we may not be able to manage our future growth effectively.

We have experienced significant growth in a short period of time. For example, our revenue has increased from $1.9 million in 2001 to $8.8 million in 2002, $20.9 million in 2003 and to $92.6 million in 2004. We may not achieve similar revenue growth rates in future periods. You should not rely on the results of any prior quarterly or annual periods as an indication of our future operating performance. If we are unable to maintain adequate revenue growth, our financial results could suffer.

Our recent expansion has placed, and any future expansion will continue to place, a significant strain on our management, personnel, systems and resources. We plan to hire a significant number of additional employees to support an increase in research and development as well as increase our sales and marketing efforts. To successfully manage our growth and handle the responsibilities of being a public company, we believe we must effectively:

If we are unable to manage our growth effectively, we may not be able to take advantage of market opportunities, develop new platforms and products, satisfy customer requirements, execute our business plan or respond to competitive pressures.

Because competition for qualified personnel is intense in our industry, we may not be able to recruit and retain necessary personnel, which could negatively impact the development and sales of our platforms.

We rely heavily on the services of our key executive officers, including Gary Johnson, our President and Chief Executive Officer. In addition, our technical personnel represent a significant asset and serve as the source of our technological and product innovations. We believe our future success will depend upon our ability to retain these key employees and our ability to attract and retain other skilled managerial, engineering and sales and marketing personnel. Any of our current employees may terminate their employment with us at any time. In addition, we have an engineering facility in India, where the employee turnover rate has traditionally been significantly higher than in the United States. The competition for qualified personnel is intense in our industry. We may not be successful in attracting and retaining sufficient numbers of qualified personnel to support our anticipated growth. The loss of any of our key employees or our inability to attract or retain qualified personnel, including engineers, could delay the development and introduction of, and negatively impact our ability to sell, our platforms. We may also incur increased operating expenses and be required to divert the attention of other senior executives to recruit replacements for the loss of any key personnel.

In addition, we have recently expanded our management team. For example, Svend-Olav Carlsen, our Vice President and Chief Financial Officer, Richard Miller, our Vice President and Chief Technology Officer, and Scott Tandy, our Vice President of Strategic Marketing, have all joined us in 2004. If the integration of our management team does not go as smoothly as expected, it could negatively affect our ability to execute our business plan.

Our headquarters are located in California and, as a result, are subject to earthquakes and other catastrophes.

Our business operations depend on our ability to maintain and protect our facilities, computer systems and personnel, which are primarily located in Santa Clara, California. Santa Clara is situated on or near known earthquake fault zones. Should an earthquake or other catastrophe, such as a fire, flood, power loss, communication failure or similar event, disable our facilities, we do not have readily available alternative facilities from which to conduct our business.

Changes to financial accounting standards may affect our results of operations and cause us to change our business practices.

We prepare our financial statements to conform with generally accepted accounting principles, or GAAP, in the United States. These accounting principles are subject to interpretation by the American Institute of Certified Public Accountants, the Securities and Exchange Commission and various bodies formed to interpret and create appropriate accounting policies. A change in those policies can have a significant effect on our reported results and may affect our reporting of transactions completed before a change is announced. Changes to those rules or the questioning of current practices may adversely affect our reported financial results or the way we conduct our business. For example, accounting policies affecting many aspects of our business, including rules relating to employee stock option grants, have recently been revised. The Financial Accounting Standards Board and other agencies have made changes to U.S. generally accepted accounting principles that will require us, starting in our first quarter of 2006, to record a charge to earnings for employee stock option grants and other equity incentives. We may have significant and ongoing accounting charges resulting from option grant and other equity incentive expensing that could reduce our overall net income. In addition, since we historically have used equity-related compensation as a component of our total employee compensation program, the accounting change could make the use of equity-related compensation less attractive to us and therefore make it more difficult to attract and retain employees.

If the personal media player does not achieve broad market adoption, our operating results will suffer.

Our platforms are designed for use in personal media players that aim to provide consumers with the ability to capture, store and play audio, photo or video content. The success of our platforms depends in part on consumers’ desire to purchase personal media players that integrate a variety of media, as well as on other companies’ willingness to design and produce personal media players and provide the necessary content. Personal media players have only been introduced to the commercial market in the last few years. The timing of broad market adoption of personal media players will depend in part on:

If the personal media player market fails to further develop for any reason, we may not be able to generate significant revenue from the sales of our platforms, and our financial results would suffer.

We currently sell platforms primarily for hard disk drive-based personal media players. Sales of our platforms may decline if the storage capacity of other technologies satisfies most consumers’ needs.

One of the main competitive advantages of hard disk drive-based personal media players is that they have greater storage capacity than alternative storage technologies, such as lower-capacity flash memory. Our business strategy assumes that a substantial portion of consumers will want personal media players that provide access to a very large number of songs or photos or to very memory intensive content, such as video, and as a result will demand the greater storage offered by hard disk drive-based personal media players. However, advances in alternative storage technologies could result in greater storage capacities. In addition, products using alternative storage technologies, such as lower-capacity flash memory, are now, and will likely remain, significantly less expensive than products using hard disk drives. If the capacity of alternative storage technologies continues to increase significantly, or if consumers are unwilling to carry very large libraries of music or photos or very memory-intensive content, then demand for our platforms that are designed primarily for hard disk drive-based media players may decrease, which would negatively affect the sales of our platforms and our revenue accordingly. In addition, any changes in the cost or storage capacity of alternative storage technologies relative to hard disk drives may affect demand for our platforms. We recently introduced our PP5024 System-in-Package product, which is designed to meet the requirements for high-capacity flash memory-based personal media players. The PP5024, which is not currently commercially available in volume production, is our first flash memory-specific product. Many of our competitors have offered flash memory-specific

products for some time and many have better established products or more expertise with flash memory-specific solutions. We cannot guarantee that the PP5024 will be accepted by our target customers, will offer the features or performance that our customers require or that we anticipate, or will be available on our planned timetable or in time for our customer’s needs.

The industry standards in the personal media player market are continually evolving, and our success depends on our ability to adapt our platforms to meet these changing industry standards.

Our ability to compete depends on our ability to adapt our platforms to support relevant industry standards, such as compression algorithms, digital rights management and delivery standards. We may be required to invest significant time and effort and to incur significant expense to redesign our platforms to address relevant standards. If our platforms do not meet relevant industry standards for a significant period of time, we could miss opportunities to achieve crucial design wins.

The emergence of alternative models for downloading digital music content may impact our business in ways we cannot anticipate.

Currently, most purchased music content is available through a pay-per-download model in which consumers purchase and own the song file, which they can download and play on their personal media player. Microsoft recently introduced its digital rights management software, (“Plays-For-Sure”) which is designed to provide personal media players access to music content on a subscription basis in which consumers can pay a subscription fee to rent, rather than own, the song file. The technology seeks to add a security feature to Microsoft’s digital rights management technology to allow a personal media player to determine when a specific file has expired. If this technology is successful, it could compete with existing pay-per-download music services. We cannot predict the impact on our business should this or other similar technology or other content distribution models become widely adopted. In addition, to the extent other providers of digital content or providers of platforms or components for personal media players take market share away from Apple’s iPod and iTunes products and services, our business and results of operations could be materially harmed.

The demand for personal media players is affected by general economic conditions, which could impact our business.

The United States and international economies have recently experienced a period of slow economic growth. A sustained economic recovery is uncertain. In particular, terrorist acts and similar events, turmoil in the Middle East or war in general, could contribute to a slowdown of the market demand for luxury consumer electronic products, including demand for personal media players. If the economic recovery slows down as a result of the recent economic, political and social turmoil, or if there are further terrorist attacks in the United States or elsewhere, we may experience decreases in the demand for our platforms, which may harm our operating results. Our business has been adversely affected by previous economic downturns. For example, during the global economic downturn in 2002 to 2003, demand for many semiconductor and consumer electronics products suffered as consumers delayed purchasing decisions or changed or reduced their discretionary spending. As a result, demand for our products suffered and we had to implement headcount reductions and restructuring initiatives to align our corporate spending with a slower than anticipated revenue growth during that timeframe.

Our ability to expand our business depends on the availability of digital content.

The demand for portable audio and video products may be adversely impacted by the adoption or enforcement of limits on file sharing and downloadable music and video or new copy protection techniques. For example, the film industry has not yet decided how or whether to regulate the access and distribution of video content. If music or video content is not readily available, the demand for personal media players that use our platforms may decline, which in turn could harm our business, financial condition and results of operations.

While we believe that we currently have adequate internal controls over financial reporting, we are exposed to risks from recent legislation requiring companies to evaluate those internal controls.

Section 404 of the Sarbanes-Oxley Act of 2002 will require our management to report on, and our independent registered public accounting firm to attest to, the effectiveness of our internal control structure and procedures for financial reporting. We are currently developing programs to perform the system and process evaluation and testing necessary to comply with these requirements. This legislation is relatively new and neither companies nor accounting firms have significant experience in complying with its requirements. As a result, we expect to incur increased expense and to devote additional management resources to Section 404 compliance. In the event that our chief executive officer, chief financial officer or independent registered public accounting firm determine that our internal controls over financial reporting are not effective as defined under Section 404, investor perceptions of our company may be adversely affected and could cause a decline in the market price of our stock.

We may become subject to securities and shareholder litigation and other lawsuits that may lead to significant costs and expenses and divert management’s attention from our business, which could cause our revenue and our stock price to decline.

In the past, securities class action litigation has often been brought against public companies after periods of volatility in the market price of securities. The market price of our common stock has been subject to significant fluctuations and may continue to fluctuate or decline. For example, during the time in which our common stock has been publicly traded, the closing sale prices of our common stock on the Nasdaq National Market ranged from $31.89 on November 29, 2004 to $15.98 on April 22, 2005. In addition, the anti-takeover provisions we have adopted in the past, such as prohibiting stockholder action by written consent, or may adopt in the future may be perceived negatively by the market causing a decline in our stock price or litigation against us. Any lawsuits to which we become a party, whether ultimately resolved in our favor or not, may not be resolved quickly, and coverage limits of our insurance or our ability to pay such amounts may not be adequate to cover the fees and expenses and any ultimate resolution associated with such litigation. The size of these payments, if any, individually or in the aggregate, could seriously impair our cash reserves and financial condition. The defense of these lawsuits also could result in continued diversion of our management’s time and attention away from business operations, which could cause our financial results to decline. A failure to resolve definitively any future material litigation in which we are involved or in which we may become involved in the future, regardless of the merits of the respective cases, could also cast doubt as to our prospects in the eyes of customers, potential customers and investors, which could cause our revenues and stock price to decline.

Our ability to raise capital in the future may be limited, and our failure to raise capital when needed could prevent us from executing our growth strategy.

We believe that our existing cash and short-term investments and additional amounts available under our bank line of credit will be sufficient to meet our anticipated cash needs for at least the next 12 months. The timing and amount of our working capital and capital expenditure requirements may vary significantly depending on numerous factors, including:

If our capital resources are insufficient to satisfy our liquidity requirements, we may seek to sell additional equity securities or debt securities or obtain other debt financing. The sale of additional equity securities or convertible debt securities would result in additional dilution to our stockholders. Additional debt would result in increased expenses and could result in covenants that would restrict our operations. We have not made arrangements to obtain additional financing, and there is no assurance that financing, if required, will be available in amounts or on terms acceptable to us, if at all.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Interest Rate Risk

We do not use derivative financial instruments in our investment portfolio. Our investments are in debt instruments of the U.S. Government and its agencies, commercial paper, and high-quality corporate issuers and, by policy, limit the amount of credit exposure to any one issuer. We have investments in fixed income securities that are classified as “available-for-sale securities.” These securities, like all fixed income instruments, are subject to interest rate risk and will fall in value if market interest rates increase. We currently attempt to limit this exposure by investing primarily in short-term securities. Due to the short-term nature of our investment portfolio, we do not believe that an immediate 10% increase in interest rates would have a material effect on the fair market value of our portfolio. Since we believe we have the ability to liquidate this portfolio, we do not expect our operating results or cash flows to be materially affected to any significant degree by a sudden change in market interest rates on our investment portfolio.

Foreign Currency Exchange Risk

Our exposure to adverse movements in foreign currency exchange rates is primarily related to our wholly owned subsidiary’s operating expenses in India, denominated in the local currency. A hypothetical change of 10% in foreign currency exchange rates would not have a material impact on our consolidated financial statements or results of operations. All of our sales are transacted in U.S. dollars.

Item 4. Controls and Procedures

Evaluation of disclosure controls and procedures

We maintain disclosure controls and procedures, as defined in Rules 13a-15(e) under the Securities Exchange Act of 1934, or the Exchange Act, that are designed to ensure that information required to be disclosed by us in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in Securities and Exchange Commission rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure. In designing and evaluating our disclosure controls and procedures, management recognized that disclosure controls and procedures, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the disclosure controls and procedures are met. Our disclosure controls and procedures have been designed to meet, and management believes that they meet, reasonable assurance standards. Additionally, in designing disclosure controls and procedures, our management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible disclosure controls and procedures. The design of any disclosure controls and procedures also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions.

Based on their evaluation as of the end of the period covered by this report, our Chief Executive Officer and Chief Financial Officer have concluded that, subject to the limitations noted above, our disclosure controls and procedures were effective to ensure that material information relating to us, including our consolidated subsidiaries, is made known to them by others within those entities, particularly during the period in which this report was being prepared.

Changes in internal controls

There was no change in our internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) identified in connection with management’s evaluation described above 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.
