1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The accompanying unaudited interim condensed consolidated financial statements of Applied Micro Circuits Corporation (“AMCC” or the “Company”) have been prepared in accordance with generally accepted accounting principles for interim financial information. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. The accompanying financial statements reflect all adjustments (consisting of normal recurring accruals), which are, in the opinion of management, considered necessary for a fair presentation of the results for the interim periods presented. Interim results are not necessarily indicative of results for a full year. The Company has experienced significant quarterly fluctuations in net revenues and operating results, and expects that these fluctuations will continue.

The financial statements and related disclosures have been prepared with the presumption that users of the interim financial information have read or have access to the audited financial statements for the preceding fiscal year. Accordingly, these financial statements should be read in conjunction with the audited financial statements and the related notes thereto contained in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission for the year ended March 31, 2003.

Use of Estimates

The preparation of financial statements in accordance 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 disclosures made in the accompanying notes to the financial statements. These estimates include among others, assessing the collectibility of accounts receivable, inventory valuation, costs of future product returns under warranty, the valuation of deferred income taxes, and the fair value and useful lives of intangible assets. Actual results could differ from those estimates.

Reclassification

Certain prior period amounts have been reclassified to conform to the current period presentation.

Stock-Based Compensation

The Company has in effect several stock option plans under which non-qualified and incentive stock options have been granted to employees and non-employee directors. The Company also has in effect an employee stock purchase plan. The Company accounts for stock-based awards to employees in accordance with Accounting Principles Board Opinion No. 25, “Accounting for Stock Issued to Employees” (“APB 25”) and the related Interpretation No. 44, “Accounting for Certain Transactions Involving Stock Compensation—An Interpretation of APB Opinion No. 25”. The Company has adopted the disclosure-only alternative of SFAS 123, “Accounting for Stock-Based Compensation” (“SFAS 123”), as amended by SFAS 148, “Accounting for Stock-Based Compensation—Transition and Disclosure” (“SFAS 148”).

Pro forma information regarding net income and net income per share is required and has been determined as if the Company had accounted for its stock-based awards under the fair value method, instead of the guidelines provided by APB 25. The fair value of the awards was estimated at the date of grant using the Black Scholes option pricing model. The Black-Scholes option valuation model was developed for use in estimating the fair value of traded options that have no vesting restrictions and are fully transferable. Option valuation models require the input of highly subjective assumptions, including the expected life and stock price volatility. Because the Company’s options have characteristics significantly different from those of traded options and because changes in the subjective input assumptions can materially affect the fair value estimate,

in the opinion of management, the existing models do not necessarily provide a reliable single measure of the fair value of its options.

The per share fair value of options granted in connection with stock option plans and rights granted in connection with the employee stock purchase plan reported below has been estimated at the date of grant with the following weighted average assumptions:

For purposes of pro forma disclosures, the estimated fair value of the options is amortized to expense over the options’ vesting periods. The Company’s pro forma information under SFAS 123 and SFAS 148 is as follows (in thousands, except per share amounts):

Upon the implementation of SFAS 142, the Company completed the initial goodwill impairment review and recorded a non-cash charge of approximately $102.2 million to reduce the carrying value of goodwill. This charge is reflected as the cumulative effect of an accounting change in the accompanying consolidated statement of operations for the quarter ended June 30, 2002. In performing this initial fair value analysis, it became evident, as a result of lower revenue forecasts, that certain other purchased intangible assets were also impaired. As a result, the Company performed an analysis of these assets as required under SFAS 144 and recorded non-cash charges of $187.9 million for the impairment of developed technology and $16.3 million as a result of the abandonment of the MMC Networks trademark. These charges are reflected as operating expenses in the consolidated statement of operations for the quarter ended June 30, 2002.

Earnings (loss) per share:

Shares used in basic loss per share are computed using the weighted average number of common shares outstanding during each period. Shares used in diluted loss per share include the dilutive effect of common shares potentially issuable upon the exercise of stock options. The reconciliation of shares used to calculate basic and diluted loss per share consists of the following (in thousands, except per share data):

Because the Company incurred losses for the three months ended June 30, 2003 and 2002, the effect of dilutive securities totaling 3.0 million and 4.2 million equivalent shares, respectively, have been excluded from the net loss per share computations as their impact would be antidilutive.

3. RESTRUCTURING CHARGES

The Company has announced a total of three restructuring programs between July 2001 and April 2003. A summary of each of the separate programs is as follows:

The above restructuring programs resulted in a total workforce reduction of approximately 41%.

5. CONTINGENCIES

In April 2001, a series of similar federal complaints were filed against the Company and certain of its executive officers and directors. The complaints have been consolidated into a single proceeding in the U.S. District Court for the Southern District of California. In re Applied Micro Circuits Corp. Securities Litigation, lead case number 01-CV-0649-K(AB). In November 2001, the court appointed the lead plaintiff and lead plaintiff’s counsel in the consolidated proceeding, and plaintiff filed a consolidated federal complaint in January 2002. The consolidated federal complaint alleges violations of the Exchange Act and is brought as a purported shareholder class action under Sections 10(b), 20(a) and 20A of the Exchange Act and Rule 10b-5 under the Exchange Act. Plaintiff seeks monetary damages on behalf of the shareholder class. Discovery in this lawsuit has commenced. Trial is currently scheduled for calendar year 2005.

In May 2001, a series of similar state derivative actions were filed against the Company’s directors and certain executive officers. The state complaints have been coordinated and assigned to the Superior Court of California in the County of San Diego. Applied Micro Circuits Shareholders Cases, No. JCCP No. 4193. In November 2001, the court appointed liaison plaintiffs’ counsel in the coordinated proceeding, and plaintiffs filed a consolidated state complaint in December 2001. The consolidated state complaint alleges overstatement of the Company’s financial prospects, mismanagement, inflation of stock value and sale of stock at inflated prices for personal gain during the period from November 2000 through February 2001. In February 2002, the board of directors formed a special litigation committee to evaluate the claims in the consolidated state complaint. The special litigation committee retained independent legal counsel and submitted a report to the court in July 2002. Defendants filed a motion seeking dismissal of the consolidated action. In June 2003, the court denied defendants’ motion to dismiss. In July 2003, defendants filed a writ petition to the appellate court seeking reversal of the denial of the motion to dismiss, or in the alternative for summary judgment. Discovery in this lawsuit has commenced.

The Company believes that the allegations in these lawsuits are without merit and intend to defend against the lawsuits vigorously. The Company cannot predict the likely outcome of these lawsuits, and an adverse result in either lawsuit could have a material adverse effect on the Company. The lawsuits have been tendered to the Company’s insurance carriers.

The Company is also party to various claims and legal actions arising in the normal course of business, including notification of possible infringement on the intellectual property rights of third parties.

Since 1993, the Company has been named as a potentially responsible party, or PRP, along with a large number of other companies that used Omega Chemical Corporation in Whittier, California to handle and dispose of certain hazardous waste material. The Company is a member of a large group of PRPs that has agreed to fund certain remediation efforts at the Omega Chemical site for which the Company has accrued approximately $100,000. In September 2000, the Company entered into a consent decree with the Environmental Protection Agency, pursuant to which the Company agreed to fund its proportionate share of the initial remediation efforts at the Omega Chemical site.

The Company was party to binding arbitration with Paxonet Communications, Inc. regarding whether the Company had breached an alleged agreement to provide Paxonet with a loan of $4.0 million. In June 2003, the arbitrator issued an interim opinion and award, finding that the Company had not breached an alleged agreement.

In May 2003, the Company’s wholly owned subsidiary, AMCC Sales Corporation, filed a complaint against Mintera Corporation, a privately held telecommunications equipment supplier, in the Superior Court of California in the County of San Diego. AMCC Sales Corporation v. Mintera Corporation, no. GIC810669. The Company is seeking recovery of amounts owed by Mintera for products supplied to Mintera and seeking a declaration that it has fulfilled its contractual obligations to Mintera pursuant to a development partner agreement. In July 2003, Mintera filed a cross-complaint in which Mintera claims that the Company made misrepresentations in order to induce Mintera to rely on the Company’s promises to release these products to production. The cross-complaint also claims that the Company breached its obligations to Mintera under the development partner agreement. Mintera also alleges in the cross-complaint that as a result of the Company’s alleged misrepresentations and alleged failure to deliver product, Mintera has suffered substantial damages. Mintera has asked for unspecified damages and punitive damages in its cross-complaint. The Company intends to file an answer to the cross-complaint denying Mintera’s allegations and claims. No discovery has taken place in this lawsuit. The lawsuit has been tendered to the Company’s insurance carriers.

Although the ultimate outcome of the pending matters is not presently determinable, the Company believes that the resolution of all such matters, net of amounts accrued, will not have a material adverse effect on its financial position or liquidity; however, there can be no assurance that the ultimate resolution of these matters will not have a material impact on its results of operations in any period.

6. RELATED PARTY TRANSACTIONS

From time to time the Company charters an aircraft for business travel from an aircraft charter company, which manages an aircraft owned by a company that AMCC’s chief executive officer controls. In the three months ended June 30, 2003 and 2002, the Company expensed a total of $100,000 and $200,000, respectively, for such charters. These amounts were within the limits on such expenses approved by the board of directors.

7. RECENT ACCOUNTING PRONOUNCEMENTS

In May 2003, the Financial Accounting Standards Board, or FASB, issued SFAS 150, “Accounting for Certain Financial Instruments with Characteristics of Both Liabilities and Equity”. The statement improves the accounting for three types of financial instruments that were previously accounted for as equity – mandatorily redeemable shares, instruments that may require the issuer to buy back shares and certain obligations that can be settled with shares. The statement requires that those instruments be accounted for as liabilities in the statement of financial position. The statement is effective for all financial instruments entered into or modified after May 31, 2003, and otherwise is effective at the beginning of the first interim period beginning after June 15, 2003. The Company does not expect the adoption of this statement to have a material impact on its operating results or financial position.

In April 2003, FASB issued SFAS 149, “Amendment of Statement 133 on Derivative Instruments and Hedging Activities”, which amends and clarifies financial accounting and reporting for derivative instruments, including certain derivative instruments embedded in other contracts and for hedging activities under SFAS No. 133, “Accounting for Derivative Instruments and Hedging Activities.” This statement is effective for contracts entered into or modified and for hedging relationships designated after June 30, 2003. The Company does not currently hold any derivative instruments and does not expect the adoption of this statement to have a material impact on its operating results or financial position.

FASB issued FASB Interpretation No. 46, “Consolidation of Variable Interest Entities”, (“FIN 46”) in January 2003. This interpretation of Accounting Research Bulletin No. 51 requires the consolidation of certain variable interest entities by the primary beneficiary. FIN 46 is effective immediately for all variable interest entities created after January 31, 2003, and applies in the first interim or annual period occurring subsequent to June 15, 2003 for variable interest entities created prior to February 1, 2003. The Company does not expect the adoption of FIN 46 to have a material effect on its operating results or financial position.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Management’s discussion and analysis of financial condition and results of operations, or MD&A, is provided as a supplement to the accompanying consolidated financial statements and footnotes to help provide an understanding of our financial condition, changes in our financial condition and results of our operations. The MD&A is organized as follows:

CAUTION CONCERNING FORWARD-LOOKING STATEMENTS

This section should be read in conjunction with the consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended March 31, 2003. This report, and in particular the MD&A, contains forward-looking statements. These forward-looking statements are made as of the date of this report. Any statement that refers to an expectation, projection or other characterization of future events or circumstances, including the underlying assumptions, is a forward-looking statement. We use certain words and their derivatives such as “anticipate”, “believe”, “plan”, “expect”, “estimate”, “predict”, “intend”, “may”, “will”, “should”, “could”, “future”, “potential”, and similar expressions in many of the forward-looking statements. The forward-looking statements are based on our current expectations, estimates and projections about our industry, management’s beliefs, and other assumptions made by us. These statements and the expectations, estimates, projections, beliefs and other assumptions on which they are based are subject to many risks and uncertainties and are inherently subject to change. We describe many of the risks and uncertainties that we face in the “Risk Factors” section of MD&A. We update our descriptions of the risks and uncertainties facing us in our periodic reports filed with the SEC in which we report our financial condition and results for the quarter and fiscal year-to-date. Our actual results and actual events could differ materially from those anticipated in any forward-looking statement. Readers should not place undue reliance on any forward-looking statement.

OVERVIEW

We design, develop, manufacture, and market high-performance, high-bandwidth silicon integrated circuits, or ICs, empowering wide area networks. We utilize a combination of digital, mixed-signal and high-frequency analog design expertise coupled with system-level knowledge and multiple silicon process technologies to offer IC products that enable the transport of voice and data over fiber optic networks, as well as chips that send T1 and T3 signals over coaxial cable networks. Our system solution portfolio includes switch fabric, traffic management, network processor, framer/mapper, and physical layer devices that address the high-performance needs of the evolving intelligent optical network. In addition, we supply silicon ICs for the automated test equipment, or ATE, high-speed computing and military markets.

CRITICAL ACCOUNTING POLICIES

The SEC Financial Reporting Release No. 60, “Cautionary Advice Regarding Disclosure About Critical Accounting Policies”, or FRR 60, encourages companies to provide additional disclosure and commentary on their most critical accounting policies. In FRR 60, the SEC defined the most critical accounting policies as the ones that are most important to the portrayal of a company’s financial condition and operating results, and require management to make its most difficult, subjective or complex judgments, often as a result of the need to make estimates about the effect of matters that are inherently uncertain. Based on this definition, our most critical accounting policies include: inventory valuation, which affects our cost of sales and gross margin; the valuation of purchased intangibles and goodwill, which affects our

12

Table of Contents

amortization and write-offs of goodwill and other intangibles; the valuation of restructuring liabilities, which affects the amount and timing of restructuring charges; and the valuation of deferred income taxes, which affects our income tax expense and benefit. We also have other key accounting policies, such as our policies for revenue recognition, including the deferral of a portion of revenues on sales to distributors, and allowance for bad debt. The methods, estimates and judgments we use in applying these most critical accounting policies have a significant impact on the results we report in our financial statements.

Inventory Valuation

Our policy is to value inventories at the lower of cost or market on a part-by-part basis. This policy requires us to make estimates regarding the market value of our inventories, including an assessment of excess or obsolete inventories. We determine excess and obsolete inventories based on an estimate of the future demand for our products within a specified time horizon, generally 12 months. The estimates we use for demand are also used for near-term capacity planning and inventory purchasing and are consistent with our revenue forecasts. If our demand forecast is greater than our actual demand we may be required to take additional excess inventory charges, which would decrease gross margin and net operating results in the future.

Goodwill and Intangible Asset Valuation

The determination of the fair value of certain acquired assets and liabilities is subjective in nature and often involves the use of significant estimates and assumptions. Determining the fair values and useful lives of intangible assets especially requires the exercise of judgment. To assist us in this process, we generally use an independent valuation firm. While there are a number of different generally accepted valuation methods to estimate the value of intangible assets acquired, we primarily use the discounted cash flow method. This method requires significant management judgment to forecast the future operating results used in the analysis. In addition, other significant estimates are required such as residual growth rates and discount factors. The estimates we use to value and amortize intangible assets are consistent with the plans and estimates that we use to manage our business and are based on available historical information and industry estimates and averages. These judgments can significantly affect our net operating results.

During 2001, the FASB issued SFAS 142, which requires that, effective April 1, 2002, goodwill and certain other intangible assets deemed to have an indefinite useful life, cease amortizing. SFAS 142 requires that goodwill and certain intangible assets be assessed for impairment using fair value measurement techniques. If the carrying amount of a reporting unit exceeds its fair value, then a goodwill impairment test is performed to measure the amount of the impairment loss, if any. The goodwill impairment test compares the implied fair value of the reporting unit’s goodwill with the carrying amount of that goodwill. The implied fair value of goodwill is determined in the same manner as in a business combination.

Determining the fair value of the implied goodwill is judgmental in nature and often involves the use of significant estimates and assumptions. These estimates and assumptions could have a significant impact on whether or not an impairment charge is recognized and also the magnitude of any such charge. To assist us in the process of determining goodwill impairment, we obtain an appraisal from an independent valuation firm. Estimates of fair value are primarily determined using discounted cash flows and market comparisons. These approaches use significant estimates and assumptions, including projection and timing of future cash flows, discount rate reflecting the risk inherent in future cash flows, perpetual growth rate, determination of appropriate market comparables, and determination of whether a premium or discount should be applied to comparables. It is reasonably possible that the plans and estimates used to value these assets may be incorrect. If our actual results, or the plans and estimates used in future impairment analyses, are lower than the original estimates used to assess the recoverability of these assets, we could incur additional impairment charges.

Restructuring Charges

Over the last two years we have undertaken significant restructuring initiatives, which have required us to develop formalized plans for exiting certain business activities. We have had to record estimated expenses for employee severance, long-term asset writedowns, lease cancellations, facilities consolidation costs, and other restructuring costs. Given the significance of, and the timing of the execution of such activities, this process is complex and involves periodic reassessments of estimates made at the time the original decisions were made. Prior to 2003, the liability for certain exit costs was recognized on the date that management committed to a plan. In 2003, new accounting guidance was issued requiring us to recognize costs associated with our exit and disposal activities at fair value when a liability is incurred. In calculating the charges for our excess facilities, we have to estimate the timing of exiting certain facilities and then estimate the future lease and operating costs to be paid until the lease is terminated and the amount of any sublease income. To form our estimates for these costs, we performed an assessment of the affected facilities and considered the current market conditions for each site. Our assumptions for the operating costs until termination or the offsetting sublease revenues may turn out to be incorrect, and our actual costs may be materially different from our estimates, which could result in the need to record additional costs or to

13

Table of Contents

reverse previously recorded liabilities. Our policies require us to periodically evaluate the adequacy of the remaining liabilities under our restructuring initiatives.

Valuation of Deferred Income Taxes

We record valuation allowances to reduce our deferred tax assets to an amount that we believe is more likely than not to be realized. We consider estimated future taxable income and ongoing prudent and feasible tax planning strategies, including reversals of deferred tax liabilities, in assessing the need for a valuation allowance. If we were to determine that we will not realize all or part of our deferred tax assets in the future, we would make an adjustment to the carrying value of the deferred tax asset, which would be reflected as income tax expense. Conversely, if we were to determine that we will realize a deferred tax asset, which currently has a valuation allowance, we would reverse the valuation allowance which would be reflected as an income tax benefit in our financial statements.

Revenue Recognition

We recognize revenue in accordance with SEC Staff Accounting Bulletin No. 101 “Revenue Recognition in Financial Statements”, or SAB 101. SAB 101 requires that four basic criteria be met before revenue can be recognized: 1) there is evidence that an arrangement exists; 2) delivery has occurred; 3) the fee is fixed or determinable; and 4) collectibility is reasonably assured. We recognize revenue upon determination that all criteria for revenue recognition have been met. The criteria are usually met at the time of product shipment, except for shipments to distributors with rights of return. Revenue from shipments to distributors with rights of return is deferred until all return or cancellation privileges lapse. In addition, we record reductions to revenue for estimated allowances such as returns and competitive pricing programs. If actual returns or pricing adjustments exceed our estimates, additional reductions to revenue would result.

Allowance for Bad Debt

We maintain an allowance for doubtful accounts for estimated losses resulting from the inability of our customers to make required payments. Our allowance for doubtful accounts is based on our assessment of the collectibility of specific customer accounts, the aging of accounts receivable, our history of bad debts, and the general condition of the industry. If a major customer’s credit worthiness deteriorates, or our customers’ actual defaults exceed our historical experience, our estimates could change and impact our reported results.

RESULTS OF OPERATIONS

Net Revenues. Net revenues for the three months ended June 30, 2003 were approximately $20.5 million, representing a decrease of 32% from the net revenues of approximately $30.2 million for the three months ended June 30, 2002. The decline in total net revenues was primarily due to a decrease in non-communications revenues related to the closure of the wafer fabrication facility in March 2003. Non-communications revenues decreased to $4.4 million for the three months ended June 30, 2003 from $12.1 million for the three months ended June 30, 2002, as a result of greater shipments of last-time-buy orders in fiscal 2003. Revenues from sales of communications products also decreased 11% to $16.1 million, or 78% of net revenues, for the three months ended June 30, 2003 from $18.1 million, or 60% of net revenues, for the three months ended June 30, 2002.

Based on direct shipments, net revenues to customers that exceeded 10% of total net revenues in the three months ended June 30, 2003 or 2002 were as follows:

Looking through product shipments to distributors and subcontractors to the end customers, net revenues to end customers that exceeded 10% of total net revenues in the three months ended June 30, 2003 or 2002 were as follows:

14

Table of Contents

Revenues based on direct shipments outside of North America accounted for 47% of net revenues for the three months ended June 30, 2003, compared to 29% for the three months ended June 30, 2002.

Gross Margin. Gross margin was 52.3% for the three months ended June 30, 2003, as compared to 41.5% for the three months ended June 30, 2002. The increase was primarily attributed to the reduced fixed cost of manufacturing overhead as a result of the permanent closure of our internal wafer fabrication facility in March 2003 and the effects of the workforce reduction announced in April 2003, as well as decreased stock-based compensation charges included in cost of revenues.

The amortization of purchased intangible assets included in cost of revenues was $1.6 million for each of the three months ended June 30, 2003 and 2002. We expect amortization expense for purchased intangibles charged to cost of revenues to be $6.3 million, $6.3 million and $3.1 million for the fiscal years ending March 31, 2004, 2005 and 2006, respectively.

Research and Development. Research and development, or R&D, expenses consist primarily of salaries and related costs of employees engaged in research, design and development activities, costs related to engineering design tools, subcontracting costs and facilities expenses. R&D expenses decreased 18% to approximately $29.1 million for the three months ended June 30, 2003, from approximately $35.5 million for the three months ended June 30, 2002. The decrease in R&D was a result of lower payroll and related benefits expense following the April 2003 workforce reduction and reduced subcontracting costs after streamlining and prioritizing our product development efforts, which were offset in part by the purchase of certain intellectual property in June 2003. We believe that a continued commitment to R&D is vital to our goal of maintaining a leadership position with innovative communications products. Currently, R&D expenses are focused on the development of products for the communications markets, and we expect to continue this focus. We expect R&D in absolute dollars to continue to decrease throughout fiscal 2004, as we continue to streamline our cost structure and implement our restructuring plan announced in April 2003. See “Restructuring Charges”. Future acquisitions of businesses may result in substantial additional charges.

Selling, General and Administrative. Selling, general and administrative, or SG&A, expenses consist primarily of personnel-related expenses, professional and legal fees, corporate branding and facilities expenses. SG&A expenses were approximately $10.4 million for the three months ended June 30, 2003, as compared to approximately $16.3 million for the three months ended June 30, 2002, representing a decrease of 37%. The decrease in SG&A expenses was primarily attributed to the effect of lower payroll and related benefits expense following the April 2003 workforce reduction and decreased commissions as a result of lower net revenues and the termination of certain sales representatives, as well as lower travel costs, marketing expenses and legal fees. We expect SG&A in absolute dollars to remain consistent throughout fiscal 2004. Future acquisitions of businesses may result in substantial additional charges.

Stock-Based Compensation. Stock-based compensation expense represents the amortization of deferred compensation related to acquisitions. Deferred compensation is the difference between the fair value of our common stock at the date of each acquisition and the exercise price of the unvested stock options assumed in the acquisition. In fiscal 2001, we recorded approximately $438.8 million of deferred compensation, in connection with stock options assumed in our purchase acquisitions. Stock-based compensation charges, including amounts charged to cost of revenues, were $12.8 million and $68.7 million for the three months ended June 30, 2003 and 2002, respectively. The charges for the three months ended June 30, 2002 included acceleration of compensation charges resulting from the voluntary cancellation of certain employees’ stock options in connection with our stock option exchange program and continued reductions resulting from employee turnover. We currently expect to record amortization of deferred compensation with respect to these assumed options of approximately $22.8 million in fiscal 2004 and $387,000 in fiscal 2005. These charges could be further reduced as a result of employee turnover. Future acquisitions of businesses may result in substantial additional charges. Such charges may cause fluctuations in our interim or annual operating results.

Goodwill and Purchased Intangible Asset Impairment Charges. Upon adoption of SFAS 142 during the first quarter of fiscal 2003, we completed our initial goodwill impairment review. As a result, in the three months ended June 30, 2002 we recorded a $102.2 million non-cash charge for the impairment of goodwill, which is reflected as the cumulative effect of an accounting change. In performing the fair value analysis as required under SFAS 142, it became evident, as a result of lower revenue forecasts, that certain other purchased intangible assets were also impaired. As a result, we performed an analysis of these assets as required under SFAS 144 and recorded non-cash charges in the three months ended June 30, 2002 of $187.9 million for the impairment of developed technology and $16.3 million as a result of the abandonment of the MMC Networks trademark. These amounts are reflected as components of operating loss.

Restructuring Charges. We have announced a total of three restructuring programs between July 2001 and April 2003. A summary of each of the separate programs is as follows:

15

Table of Contents

The above restructuring programs resulted in a total workforce reduction of approximately 41%.

Net Interest Income. Net interest income reflects interest earned on cash and cash equivalents and short-term investment balances, as well as realized gains and losses from the sale of short-term investments, less interest expense on our debt and capital lease obligations. Net interest income increased slightly to $11.4 million for the three months ended June 30, 2003, from $10.9 million for the three months ended June 30, 2002, due to higher realized gains on sales of short-term investments in the portfolio, offset by lower interest income as a result of lower yields and cash balances.

Income Taxes. We recorded no income taxes for the three months ended June 30, 2003 and 2002. The difference between our effective tax rate and the federal statutory rate for those periods resulted from the establishment of valuation allowances for the deferred tax assets generated, as it is more likely than not that they will expire unused.

Cumulative Effect of Accounting Change. As a result of our initial goodwill impairment review performed as of April 1, 2002 as required by the adoption of SFAS 142, we recorded a non-cash charge of $102.2 million in the three months ended June 30, 2002.

Financial Condition and Liquidity

As of June 30, 2003, our principal source of liquidity consisted of $1.0 billion in cash, cash equivalents and short-term investments. Working capital as of June 30, 2003 was also $1.0 billion. At the end of June 30, 2003, we had contractual obligations not included on our balance sheet totaling $45.6 million, primarily related to facilities and engineering design software tools.

For the three months ended June 30, 2003, we used $12.2 million of cash to fund our operations compared to using $6.2 million for our operations in the three months ended June 30, 2002. Although we had a net loss of $53.4 million for the three months ended June 30, 2003, $27.9 million consisted of non-cash charges such as depreciation, amortization and non-cash restructuring charges. Excluding non-cash charges, operating cash flows for the three months ended June 30, 2003 primarily reflected increases in accrued liabilities and accounts receivables and decreases in other assets and accounts payable. Operating cash flows for the three months ended June 30, 2002 consists of operating results before non-cash charges, in addition to decreases in inventory, other assets and accounts payable, and an increase in accrued liabilities.

We generated $15.0 million of cash from investing activities during the three months ended June 30, 2003, compared to using $148.1 million during the three months ended June 30, 2002. The inflow of cash for the three months ended June 30, 2003 primarily represents a move to shorten the duration of the investment portfolio.

Capital expenditures totaled $505,000 and $2.3 million for the three months ended June 30, 2003 and 2002, respectively. These capital expenditures primarily consisted of purchases of engineering hardware and design software.

We generated $169,000 of cash for the three months ended June 30, 2003 from financing activities compared to generating $780,000 for the three months ended June 30, 2002. The major financing source of cash was from the sale of our common stock through the exercise of employee stock options. The major use of cash from financing activities was for the repayment of debt and capital lease obligations.

Table of Contents

On October 16, 2002, our board of directors approved a stock repurchase program whereby we were authorized to expend up to $200.0 million to purchase our common stock. Depending on market conditions and other factors, purchases may be made from time to time in the open market and in negotiated transactions, including block transactions, at times and prices considered appropriate by us. Such program may be discontinued at any time. As of June 30, 2003, we had not made any purchases under the program.

We believe that our available cash, cash equivalents and short-term investments will be sufficient to meet our capital requirements and fund our operations for at least the next 12 months, although we could elect or could be required to raise additional capital during such period. There can be no assurance that such additional debt or equity financing will be available on commercially reasonable terms or at all.

The following table summarizes our contractual obligations as of June 30, 2003 (in thousands):

RISK FACTORS

Before deciding to invest in us or to maintain or increase your investment, you should carefully consider the risks described below, in addition to the other information contained in this report and in our other filings with the SEC. We update our descriptions of the risks and uncertainties facing us in our periodic reports filed with the SEC in which we report our financial condition and results for the quarter and fiscal year-to-date. The risks and uncertainties described below and in our other filings are not the only ones facing us. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also affect our business. If any of these known or unknown risks or uncertainties actually occurs, our business, financial condition and results of operations could be seriously harmed. In that event, the market price for our common stock could decline and you may lose your investment.

Our operating results may fluctuate because of a number of factors, many of which are beyond our control.

If our operating results are below the expectations of public market analysts or investors, then the market price of our common stock could decline. Some of the factors that affect our quarterly and annual results, but which are difficult to control or predict are:

18

Table of Contents

Our business, financial condition and operating results would be harmed if we do not achieve anticipated revenues.

We can have revenue shortfalls for a variety of reasons, including:

Our business is characterized by short-term orders and shipment schedules. Customer orders typically can be cancelled or rescheduled without significant penalty to the customer. Because we do not have substantial noncancellable backlog, we typically plan our production and inventory levels based on internal forecasts of customer demand, which are highly unpredictable and can fluctuate substantially. Our revenues are typically derived from sales of application specific standard products, or ASSPs, as compared to application specific integrated circuits, or ASICs. Customer orders for ASSPs typically have shorter lead times than orders for ASICs, which makes it more difficult for us to predict revenues and inventory levels and adjust production appropriately. If we are unable to plan inventory and production levels effectively, our business, financial condition and operating results could be materially harmed.

From time to time, in response to anticipated long lead times to obtain inventory and materials from our outside suppliers and foundries, we may order materials in advance of anticipated customer demand. This advance ordering has in the past and may in the future result in excess inventory levels or unanticipated inventory write-downs if expected orders fail to materialize, or other factors render our products less marketable. Accordingly, our financial condition and operating results could be materially harmed.

Our expense levels are relatively fixed and are based on our expectations of future revenues. We have limited ability to reduce expenses quickly in response to any revenue shortfalls.

If the downturn in the communications equipment industry continues, our revenues and profitability will continue to be adversely affected.

We derive a majority of our revenues from communications equipment manufacturers. The communications equipment industry is experiencing a significant extended downturn and as a result, the financial condition of many telecommunications

19

Table of Contents

companies has significantly declined. This downturn has severely affected carrier capital equipment expenditures, which in turn has affected the demand for our products and our revenues and profitability. We cannot predict how long this downturn will last, but as long as it does, our revenues and profitability will continue to be impacted. Our need to continue investment in research and development during this downturn and to maintain extensive ongoing customer service and support constrains our ability to reduce expenses.

We expect revenues that are currently derived from non-communications markets will decline in future periods.

We derived significant revenues from product sales to customers in the ATE, high-speed computing and military markets in the past. The majority of these products were manufactured at our internal wafer fabrication facility, which closed in March 2003. Throughout fiscal 2003, we were fulfilling last-time-buy orders for parts manufactured in this facility. As a result of the last-time-buy program, our revenues from sales of our non-communications products decreased to 22% of net revenues for the quarter ended June 30, 2003 from 40% of net revenues for the quarter ended June 30, 2002. We expect that revenues from our non-communications products will continue to decline materially as we fulfill the last-time-buy orders throughout most of fiscal 2004. We will continue to sell products for these markets for the foreseeable future, but the volumes and revenues are expected to be modest.

Our business substantially depends upon the continued growth of the Internet.

A substantial portion of our business and revenue depends on the continued growth of the Internet. We sell our products primarily to communications equipment manufacturers that in turn sell their equipment to customers that depend on the growth of the Internet. As a result of the economic slowdown, the significant decline in the financial condition of many telecommunications companies and the reduction in capital spending, spending on Internet infrastructure has declined. To the extent that the economic slowdown and reduction in capital spending continues to adversely affect spending on Internet infrastructure, our business, operating results, and financial condition will continue to be materially harmed.

Our customers are concentrated. The loss of one or more key customers or the diminished demand for our products from a key customer could significantly reduce our revenues and profits.

A relatively small number of customers have accounted for a significant portion of our revenues in any particular period. We have no long-term volume purchase commitments from any of our key customers. Many of our key customers have announced dramatic declines in demand for their products into which our products are incorporated. As a result, new orders from these customers have been deferred, and customers may have overstocked our products. One or more of our key customers may discontinue operations as a result of consolidation, liquidation or otherwise. Continued reductions, delays and cancellation of orders from our key customers or the loss of one or more key customers could significantly further reduce our revenues and profits. We cannot assure you that our current customers will continue to place orders with us, that orders by existing customers will continue at current or historical levels or that we will be able to obtain orders from new customers.

Our ability to maintain or increase sales to key customers and attract new significant customers is subject to a variety of factors, including:

20

Table of Contents

The occurrence of any one of the factors above could have a material adverse effect on our business, financial condition and results of operations.

Any significant order cancellations or order deferrals could adversely affect our operating results.

We typically sell products pursuant to purchase orders that customers can generally cancel or defer on short notice without incurring a significant penalty. Any significant cancellations or deferrals in the future could materially and adversely affect our business, financial condition and results of operations. Cancellations or deferrals could cause us to hold excess inventory, which could reduce our profit margins, increase product obsolescence and restrict our ability to fund our operations. We generally recognize revenue upon shipment of products to a customer. If a customer refuses to accept shipped products or does not pay for these products, we could miss future revenue projections or incur significant charges against our income, which could materially and adversely affect our operating results.

An important part of our strategy is to continue our focus on the markets for wireline communications ICs. If we are unable to further expand our share of these markets, our revenues may not grow and could further decline.

Our markets frequently undergo transitions in which products rapidly incorporate new features and performance standards on an industry-wide basis. If our products are unable to support the new features or performance levels required by OEMs in these markets, we would be likely to lose business from an existing or potential customer and would not have the opportunity to compete for new design wins until the next product transition occurs. If we fail to develop products with required features or performance standards, or if we experience a delay as short as a few months in bringing a new product to market, or if our customers fail to achieve market acceptance of their products, our revenues could be significantly reduced for a substantial period.

We expect a significant portion of our revenues to continue to be derived from sales of products based on current, widely accepted transmission standards. If the communications market evolves to new standards, we may not be able to successfully design and manufacture new products that address the needs of our customers or gain substantial market acceptance. Although we have developed products for the Gigabit Ethernet and fibre channel communications standards, sales volumes of these products are modest, and we may not be successful in addressing the market opportunities for products based on these standards.

Customers for our products generally have substantial technological capabilities and financial resources. They traditionally use these resources to internally develop their own products. The future prospects for our products in these markets are dependent upon our customers’ acceptance of our products as an alternative to their internally developed products. Future prospects also are dependent upon acceptance of third-party sourcing for products as an alternative to in-house development. Network equipment vendors may in the future continue to use internally developed components. They also may decide to develop or acquire components, technologies or products that are similar to, or that may be substituted for, our products.

If our network equipment vendor customers fail to accept our products as an alternative, if they develop or acquire the technology to develop such components internally rather than purchase our products, or if we are otherwise unable to develop strong relationships with network equipment vendors, our business, financial condition and results of operations would be materially and adversely affected.

Our industry and markets are subject to consolidation, which may result in stronger competitors, fewer customers and reduced demand.

There has been industry consolidation among communications IC companies, network equipment companies and telecommunications companies in the past. We expect this consolidation to continue as companies attempt to strengthen or hold their positions in evolving markets. Consolidation may result in stronger competitors, fewer customers and reduced demand, which in turn could have a material adverse effect on our business, operating results, and financial condition.

Our operating results are subject to fluctuations because we rely heavily on international sales.

International sales account for a significant part of our revenues and may account for an increasing portion of our future revenues. As a result, an increasing portion of our revenues may be subject to certain risks, including:

21

Table of Contents

We are subject to risks associated with the imposition of legislation and regulations relating to the import or export of high technology products. We cannot predict whether quotas, duties, taxes or other charges or restrictions upon the importation or exportation of our products will be implemented by the United States or other countries. Because sales of our products have been denominated to date primarily in United States dollars, increases in the value of the United States dollar could increase the price of our products so that they become relatively more expensive to customers in the local currency of a particular country, leading to a reduction in sales and profitability in that country. Future international activity may result in increased foreign currency denominated sales. Gains and losses on the conversion to United States dollars of accounts receivable, accounts payable and other monetary assets and liabilities arising from international operations may contribute to fluctuations in our results of operations. Some of our customer purchase orders and agreements are governed by foreign laws, which may differ significantly from United States laws. We may be limited in our ability to enforce our rights under such agreements.

Our cash and cash equivalents and portfolio of short-term investments are exposed to certain market risks.

We maintain an investment portfolio of various holdings, types and maturities. These securities are recorded on the consolidated balance sheets at fair value with unrealized gains or losses reported as a separate component of accumulated other comprehensive income (loss), net of tax. Our investment portfolio is exposed to market risks related to changes in interest rates, credit ratings of the issuers and foreign currency exchange rates, as well as the risk of default by the issuer. Substantially all of these securities are subject to interest rate and credit rating risk and will decline in value if interest rates increase or one of the issuers’ credit ratings is reduced. We currently do not use derivative financial instruments to manage any of these risks. Increases in interest rates, decreases in the credit worthiness of one or more of the issuers in the portfolio or adverse changes in foreign currency exchange rates could have a material adverse impact on our financial condition or results of operations.

Our recently implemented restructuring plan could result in management distractions, operational disruptions and other difficulties.

As a result of the continuing significant economic slowdown and the related uncertainties in our industry, we implemented a new restructuring plan in the first quarter of fiscal 2004. The plan focused on cost reductions and operating efficiencies, and included workforce reductions. Employees directly affected by the reductions may seek future employment with our customers or competitors. Although all employees are required to sign a confidentiality agreement with us at the time of hire, we cannot assure you that the confidential nature of our proprietary information will be maintained in the course of such future employment. Our restructuring efforts could divert the attention of our management away from our operations, harm our reputation and increase our expenses. We cannot assure you that our restructuring efforts will be successful, that future operations will improve or that the completion of restructuring will not disrupt our operations. If we continue to reduce our workforce, it may adversely impact our ability to respond rapidly to any renewed growth opportunities.

Our markets are subject to rapid technological change, so our success depends heavily on our ability to develop and introduce new products.

The markets for our products are characterized by:

22

Table of Contents

To develop new products for the communications markets, we must develop, gain access to and use leading technologies in a cost-effective and timely manner and continue to develop technical and design expertise. We must have our products designed into our customers’ future products and maintain close working relationships with key customers in order to develop new products that meet customers’ changing needs. We must respond to changing industry standards, trends towards increased integration and other technological changes on a timely and cost-effective basis. Our pursuit of technological advances may require substantial time and expense and may ultimately prove unsuccessful. If we are not successful in introducing such advances, we will be unable to timely bring to market new products and our revenues will suffer.

Products for communications applications are based on industry standards that are continually evolving. Our ability to compete in the future will depend on our ability to identify and ensure compliance with these evolving industry standards. The emergence of new industry standards could render our products incompatible with products developed by major systems manufacturers. As a result, we could be required to invest significant time and effort and to incur significant expense to redesign our products to ensure compliance with relevant standards. If our products are not in compliance with prevailing industry standards, we could miss opportunities to achieve crucial design wins. If we fail to do so, we may not achieve design wins with key customers or may subsequently lose such design wins, and our business will significantly suffer because once a customer has designed a supplier’s product into its system, the customer typically is extremely reluctant to change its supply source due to significant costs associated with qualifying a new supplier.

The markets in which we compete are highly competitive and subject to rapid technological change, price erosion and heightened competition.

The communications IC markets are highly competitive and we expect that competition will increase in these markets, due in part to deregulation and heightened international competition. Our ability to compete successfully in our markets depends on a number of factors, including:

Our competitors may offer enhancements to existing products, or offer new products based on new technologies, industry standards or customer requirements, that are available to customers on a more timely basis than comparable products from us or that have the potential to replace or provide lower cost alternatives to our products. The introduction of such enhancements or new products by our competitors could render our existing and future products obsolete or unmarketable. Once a customer has designed a supplier’s product into its system, the customer is unlikely to change its supply source due to the significant costs associated with qualifying a new supplier. We expect that certain of our competitors and other semiconductor companies may seek to develop and introduce products that integrate the functions performed by our IC

23

Table of Contents

products on a single chip, thus eliminating the need for our products. Each of these factors could have a material adverse effect on our business, financial condition and results of operations.

In the communications markets, we compete primarily against companies such as Agere, Broadcom, Intel, Mindspeed, PMC-Sierra, and Vitesse. Certain of our customers or potential customers have internal IC design or manufacturing capability with which we compete. Any failure by us to compete successfully in these target markets, particularly in the communications markets, would have a material adverse effect on our business, financial condition and results of operations.

The closing of our internal wafer fabrication facility could result in unanticipated liability and reduced revenues.

A significant portion of our fiscal 2003 revenues was derived from products manufactured in our internal wafer fabrication facility. As of March 31, 2003, the facility closed and we do not have the ability to manufacture products in the facility, which subjects us to substantial risks, including:

A disruption in the manufacturing capabilities of our outside foundries would negatively impact the production of certain of our products.

In the past, we relied on outside foundries for the manufacture of the majority of our products. Now that we have closed our internal foundry, all of our products will be manufactured by outside foundries. These outside foundries generally manufacture our products on a purchase order basis, and we generally do not have long-term supply arrangements with these suppliers. A manufacturing disruption experienced by one or more of our outside foundries or a disruption of our relationship with an outside foundry, including discontinuance of our products by that foundry, would negatively impact the production of certain of our products for a substantial period of time. The transition to the next generation of manufacturing technologies at one or more of our outside foundries could be unsuccessful or delayed.

A majority of our products are only qualified for production at a single foundry. These suppliers can allocate, and in the past have allocated, capacity to the production of other companies’ products while reducing deliveries to us on a short notice. Because establishing relationships and ramping production with new outside foundries may take over a year, there is no readily available alternative source of supply for these products.

Our dependence on third-party manufacturing and supply relationships increases the risk that we will not have an adequate supply of products to meet demand or that our cost of materials will be higher than expected.

The risks associated with our dependence upon third parties which manufacture, assemble or package certain of our products, include:

Difficulties associated with adapting our technology and product design to the proprietary process technology and design rules of outside foundries can lead to reduced yields. The process technology of an outside foundry is typically proprietary to the manufacturer. Since low yields may result from either design or process technology failures, yield problems may not be effectively determined or resolved until an actual product exists that can be analyzed and tested to identify process sensitivities relating to the design rules that are used. As a result, yield problems may not be identified until well into the

24

Table of Contents

production process, and resolution of yield problems may require cooperation between us and our manufacturer. This risk could be compounded by the offshore location of certain of our manufacturers, increasing the effort and time required to identify, communicate and resolve manufacturing yield problems. Manufacturing defects that we do not discover during the manufacturing or testing process may lead to costly product recalls. These risks may lead to increased costs or delayed product delivery, which would harm our profitability and customer relationships.

If the foundries or subcontractors we use to manufacture our products discontinue the manufacturing processes needed to meet our demands, or fail to upgrade their technologies needed to manufacture our products, we may be unable to deliver products to our customers, which could materially adversely affect our operating results.

Our requirements typically represent a very small portion of the total production of the third-party foundries. As a result, we are subject to the risk that a producer will cease production of an older or lower-volume process that it uses to produce our parts. We cannot be certain our external foundries will continue to devote resources to the production of our products or continue to advance the process design technologies on which the manufacturing of our products are based. Each of these events could increase our costs and materially impact our ability to deliver our products on time.

Our operating results depend on manufacturing output and yields, which may not meet expectations.

The yields on wafers we have manufactured decline whenever a substantial percentage of wafers must be rejected or a significant number of dice on each wafer are nonfunctional. Such declines can be caused by many factors, including minute levels of contaminants in the manufacturing environment, design issues, defects in masks used to print circuits on a wafer, and difficulties in the fabrication process. Design iterations and process changes by our suppliers can cause a risk of defects. Many of these problems are difficult to diagnose, are time consuming and expensive to remedy, and can result in shipment delays.

We estimate yields per wafer in order to estimate the value of inventory. If yields are materially different than projected, work-in-process inventory may need to be revalued. We may have to take inventory write-downs as a result of decreases in manufacturing yields. We may suffer periodic yield problems in connection with new or existing products or in connection with the commencement of production at a new manufacturing facility.

We may experience difficulties in transitioning to smaller geometry process technologies or in achieving higher levels of design integration and that may result in reduced manufacturing yields, delays in product deliveries and increased expenses.

We expect to transition our products to increasingly smaller line width geometries. This transition will require us to migrate to new manufacturing processes for our products and redesign certain products. We periodically evaluate the benefits, on a product-by-product basis, of migrating to smaller geometry process technologies to reduce our costs and increase performance, and we have designed products to be manufactured at as little as .13 micron geometry processes. We have experienced some difficulties in shifting to smaller geometry process technologies or new manufacturing processes. These difficulties resulted in reduced manufacturing yields, delays in product deliveries and increased expenses. We may face similar difficulties, delays and expenses as we continue to transition our products to smaller geometry processes. We are dependent on our relationships with our foundries to transition to smaller geometry processes successfully. We cannot assure you that our foundries will be able to effectively manage the transition or that we will be able to maintain our relationships with our foundries. If we or our foundries experience significant delays in this transition or fail to implement this transition, our business, financial condition and results of operations could be materially and adversely affected. As smaller geometry processes become more prevalent, we expect to continue to integrate greater levels of functionality into our products. We may not be able to achieve higher levels of design integration or deliver new integrated products on a timely basis.

We must develop or otherwise gain access to improved process technologies.

Our future success will depend upon our ability to improve existing process technologies or acquire new process technologies. In the future, we may be required to transition one or more of our products to process technologies with smaller geometries, other materials or higher speeds in order to reduce costs or improve product performance. We may not be able to improve our process technologies or otherwise gain access to new process technologies in a timely or affordable manner. Products based on these technologies may not achieve market acceptance.

The complexity of our products may lead to errors, defects and bugs when they are first introduced, which could negatively impact our reputation with customers and result in liability.

Products as complex as ours may contain errors, defects and bugs when first introduced or as new versions are released. Our products have in the past experienced such errors, defects and bugs. Delivery of products with production defects or reliability, quality or compatibility problems could significantly delay or hinder market acceptance of the products or result in a costly recall. This, in turn, could damage our reputation and adversely affect our ability to retain existing customers and to

25

Table of Contents

attract new customers. Errors, defects or bugs could cause problems with device functionality, resulting in interruptions, delays or cessation of sales to our customers.

We may also be required to make significant expenditures of capital and resources to resolve such problems. There can be no assurance that problems will not be found in new products after commencement of commercial production, despite testing by us, our suppliers or our customers. This could result in:

Any such event could have a material adverse effect on our business, financial condition and results of operations.

Our future success depends in part on the continued service of our key design engineering, sales, marketing, manufacturing, and executive personnel and our ability to identify, hire and retain additional, qualified personnel.

There is intense competition for qualified personnel in the semiconductor industry, in particular design, product and test engineers, and we may not be able to continue to attract and retain engineers or other qualified personnel necessary for the development of our business, or to replace engineers or other qualified personnel who may leave our employment in the future. Periods of contraction in our business may inhibit our ability to attract and retain our personnel. Loss of the services of, or failure to recruit, key design engineers or other technical and management personnel could be significantly detrimental to our product development.

To manage operations effectively, we will be required to continue to improve our operational, financial and management systems and to successfully hire, train, motivate, and manage our employees. The integration of past and future potential acquisitions will require significant additional management, technical and administrative resources. We cannot be certain that we would be able to manage our expanded operations effectively.

Our ability to supply a sufficient number of products to meet demand could be severely hampered by a shortage of water, electricity or other supplies, or by natural disasters or other catastrophes.

The manufacture of our products requires significant amounts of water. Previous droughts have resulted in restrictions being placed on water use by manufacturers. In the event of a future drought, reductions in water use may be mandated generally and our external foundries’ ability to manufacture our products could be impaired.
