NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)

Note 1: Background and Basis of Presentation

ON Semiconductor Corporation, together with its wholly and majority-owned subsidiaries (the “Company”), is a global supplier of power and data management semiconductors and standard semiconductor components. The Company was a wholly-owned subsidiary of Motorola Inc. (“Motorola”) prior to its August 4, 1999 recapitalization (the “recapitalization”).

On August 4, 1999, the Company was recapitalized and certain related transactions were effected pursuant to an agreement among ON Semiconductor Corporation, its principal domestic operating subsidiary, Semiconductor Components Industries, LLC (“SCI LLC”), Motorola and affiliates of Texas Pacific Group (“TPG”). Because TPG’s affiliates did not acquire substantially all of the Company’s common stock, the basis of the Company’s assets and liabilities for financial reporting purposes was not impacted by the recapitalization.

The accompanying unaudited financial statements as of March 31, 2006, and for the quarter ended March 31, 2006 and April 1, 2005, respectively, 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 audited financial statements. In the opinion of the Company’s management, the interim information includes all adjustments, consisting only of normal recurring adjustments, necessary for a fair statement of the results for the interim periods. The footnote disclosures related to the interim financial information included herein are also unaudited. Such financial information should be read in conjunction with the consolidated financial statements and related notes thereto as of December 31, 2005 and for the year then ended included in the Company’s annual report on Form 10-K for the year ended December 31, 2005.

Note 2: Liquidity

During the quarter ended March 31, 2006, the Company reported net income of $40.4 million compared to $14.8 million for the quarter ended April 1, 2005. The Company’s net income included charges of $1.1 million from restructuring, asset impairments and other, net for the quarter ended April 1, 2005. Net cash provided by operating activities was $50.5 million for the quarter ended March 31, 2006, as compared to $36.2 million for the quarter ended April 1, 2005.

At March 31, 2006, the Company had $251.3 million in cash and cash equivalents, net working capital of $251.2 million, term and revolving debt of $1,062.0 million in the aggregate and a stockholders’ deficit of $249.7 million. The Company’s long-term debt includes $637.3 million under its senior bank facilities; $260.0 million of its zero coupon convertible senior subordinated notes due 2024; $95.0 million under a 1.875% senior subordinated note due 2025; $33.2 million under a loan facility with a Chinese bank due 2006 through 2013; $14.2 million under a note payable to a Japanese bank due 2006 through 2010; $14.0 million under a loan facility with a Chinese bank due 2006 through 2007; and $8.3 million of capital lease obligations. The Company was in compliance with all of the covenants contained in its various debt agreements as of March 31, 2006 and expects to remain in compliance over the next twelve months.

The Company’s ability to service its long-term debt, to remain in compliance with the various covenants and restrictions contained in its financing agreements and to fund working capital, capital expenditures and business development efforts will depend on its ability to generate cash from operating activities which is subject to, among other things, its future operating performance as well as to general economic, financial, competitive, legislative, regulatory and other conditions, some of which may be beyond its control.

If the Company fails to generate sufficient cash from operations, it may need to sell additional equity or borrow additional funds to achieve its longer term objectives. There can be no assurance that such equity or borrowings will be available or, if available, will be on terms acceptable to the Company. Management believes that cash flows from operating activities coupled with existing cash balances will be adequate to fund the Company’s operating and capital needs through March 31, 2007. To the extent that results or events differ from the Company’s financial projections or business plans, its liquidity may be adversely affected.

Note 3: Significant Accounting Policies

Principles of Consolidation

The accompanying consolidated financial statements include the accounts of the Company, as well as its wholly-owned and majority-owned subsidiaries. Investments in companies that represent less than 20% of the related voting stock are accounted for on the cost basis. All intercompany accounts and transactions have been eliminated.

In the second quarter of 2003, the Company adopted Financial Accounting Standards Board (“FASB”) Interpretation No. 46, Consolidation of Variable Interest Entities, an Interpretation of ARB No. 51, as amended December 2003 (“FIN No. 46”). FIN No. 46 requires that certain variable interest entities (“VIE’s”) be consolidated by the primary beneficiary, as that term is defined in FIN No. 46. The Company determined that its investment in Leshan-Phoenix Semiconductor Company Limited (“Leshan”) meets the definition of a VIE and that the Company is the primary beneficiary; therefore, the investment in Leshan should be consolidated under FIN No. 46. The Company had previously accounted for its investment in Leshan using the equity method.

Use of Estimates

The preparation of financial statements in accordance with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amount of assets and liabilities at the date of the financial statements and the reported amount of revenues and expenses during the reporting period. Significant estimates have been used by management in conjunction with the measurement of valuation allowances relating to trade and tax receivables, inventories and deferred tax assets; reserves for customer incentives, warranties, restructuring charges, tax reserves and pension obligations; the fair values of stock options and of financial instruments (including derivative financial instruments); and future cash flows associated with long-lived assets. Actual results could differ from these estimates.

Cash and cash equivalents

The Company considers all highly liquid investments with an original maturity of three months or less to be cash equivalents. Cash and cash equivalents are maintained with reputable major financial institutions. Deposits with these banks may exceed the amount of insurance provided on such deposits; however, these deposits typically may be redeemed upon demand and, therefore, bear minimal risk.

Allowance for Doubtful Accounts

The Company provides unsecured credit terms to its customers in the normal course of business. Accordingly, the Company maintains an allowance for doubtful accounts for possible losses on uncollectible accounts receivable. The Company routinely analyzes accounts receivable and considers history, customer creditworthiness, facts and circumstances specific to outstanding balances, current economic trends, and payment

5

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

(unaudited)

term changes when evaluating adequacy of the allowance for doubtful accounts. For uncollectible accounts receivable the Company records a loss against the allowance for doubtful accounts only after exhaustive efforts have been made to collect and with management’s approval. Generally, realized losses have been within the range of management’s expectations.

Approximately 17% of the Company’s revenues for the first quarter of 2006 are attributable to its various automotive customers. Certain of these automotive customers have been experiencing a downturn in their business, in part due to labor difficulties. On October 8, 2005, Delphi Corporation (“Delphi”), one of the Company’s automotive customers, and certain of Delphi’s U.S. subsidiaries commenced reorganization proceedings under Chapter 11 of the U.S. Federal Bankruptcy Code. During the quarter ended March 31, 2006, the Company’s revenues from Delphi accounted for less than 3% of its total revenues and approximately $5.4 million of its receivables due from Delphi as of March 31, 2006 are subject to collection pending resolution of the reorganization proceedings.

Inventories

Inventories are stated at the lower of standard cost (which approximates actual cost on a first-in, first-out basis), or market. The Company records provisions for slow moving inventories based upon a regular analysis of inventory on hand compared to projected end user demand. Projected end user demand is generally based on sales during the prior twelve months. These provisions can influence results from operations. For example, when demand for a given part falls, all or a portion of the related inventory is reserved, impacting cost of sales and gross profit. If demand recovers and the parts previously reserved are sold, a higher than normal margin will generally be recognized. General market conditions as well as the Company’s design activities can cause certain of its products to become obsolete.

Property, Plant and Equipment

Property, plant and equipment are recorded at cost and are depreciated over estimated useful lives of 30-40 years for buildings and 3-20 years for machinery and equipment using accelerated and straight-line methods. A majority of the machinery and equipment currently in use is depreciated on a straight-line basis over a useful life of 5 years. Expenditures for maintenance and repairs are charged to operations in the year in which the expense is incurred. When assets are retired or otherwise disposed of, the related costs and accumulated depreciation are removed from the accounts and any resulting gain or loss is reflected in operations in the period realized.

The Company evaluates the recoverability of the carrying amount of its property, plant and equipment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be fully recoverable. Impairment is assessed when the undiscounted expected cash flows derived from an asset are less than its carrying amount. Impairment losses are measured as the amount by which the carrying value of an asset exceeds its fair value and are recognized in operating results. Judgment is used when applying these impairment rules to determine the timing of the impairment test, the undiscounted cash flows used to assess impairments and the fair value of an impaired asset. The dynamic economic environment in which the Company operates and the resulting assumptions used to estimate future cash flows impact the outcome of these impairment tests.

In 2005, management committed to a plan to sell approximately 42 acres of land and three buildings located at its corporate headquarters in Phoenix, Arizona, as well as one of its two buildings at its East Greenwich, Rhode Island facility. The remainder of the Phoenix site will continue to function as the Company’s corporate headquarters as well as a manufacturing, design center and research and development facility. The remaining building in Rhode Island will continue to function as a design center and research and development facility. The

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

(unaudited)

property and buildings are currently being marketed for sale with a list price of between $24 million and $27 million. The net book value of the land and buildings of $3.0 million has been classified as held for sale and included in other current assets as of December 31, 2005 and March 31, 2006.

Goodwill and Other Intangible Assets

Goodwill represents the excess of the purchase price over the estimated fair value of the net assets acquired in the Company’s April 2000 acquisition of Cherry Semiconductor Corporation (Cherry). When the Company adopted Statement of Financial Accounting Standards No. 142 “Goodwill and Other Intangible Assets” (“SFAS No. 142”) the net carrying value of the Cherry Goodwill was $77.3 million, which included $18.4 million of accumulated amortization. Under SFAS No. 142, goodwill is evaluated for potential impairment on an annual basis or whenever events or circumstances indicate that an impairment may have occurred. SFAS No. 142 requires that goodwill be tested for impairment using a two-step process. The first step of the goodwill impairment test, used to identify potential impairment, compares the estimated fair value of the reporting unit containing goodwill with the related carrying amount. If the estimated fair value of the reporting unit exceeds its carrying amount, the reporting unit’s goodwill is not considered to be impaired and the second step of the impairment test is unnecessary. If the reporting unit’s carrying amount exceeds its estimated fair value, the second step test must be performed to measure the amount of the goodwill impairment loss, if any. The second step test compares the implied fair value of the reporting unit’s goodwill, determined in the same manner as the amount of goodwill recognized in a business combination, with the carrying amount of such goodwill. If the carrying amount of the reporting unit’s goodwill exceeds the implied fair value of that goodwill, an impairment loss is recognized in an amount equal to that excess. The Company performs its annual impairment analysis as of the first day of the fourth quarter of each year.

Debt Issuance Costs

Debt issuance costs are capitalized and amortized over the term of the underlying agreements using the effective interest method. Upon prepayment of debt, the related unamortized debt issuance costs are charged to expense. Amortization of debt issuance costs is included in interest expense while the unamortized balance is included in other assets. Capitalized debt issuance costs totaled $11.9 million and $11.4 million at March 31, 2006 and December 31, 2005, respectively.

Revenue Recognition

The Company generates revenue from sales of its semiconductor products to original equipment manufacturers, electronic manufacturing service providers, and distributors. The Company recognizes revenue on sales to original equipment manufacturers and electronic manufacturing service providers when title passes to the end customer net of provisions for related sales returns and allowances. Title to products sold to distributors typically passes at the time of shipment by the Company so the Company records accounts receivable for the amount of the transaction, reduces its inventory for the products shipped and defers the related margin in the consolidated balance sheet. The Company recognizes the related revenue and margin when the distributor informs the Company that it has resold the products to the end user. Although payment terms vary, most distributor agreements require payment within 30 days. Freight and handling costs are included in cost of revenues and are recognized as period expense during the period in which they are incurred.

Research and Development Costs

Research and development costs are expensed as incurred.

Share-Based Payments

In December 2004, the Financial Accounting Standards Board (“FASB”) revised Statement of Financial Accounting Standards No. 123 (“SFAS No. 123R”), “Share-Based Payment,” which establishes accounting for share-based awards exchanged for employee services and requires companies to expense the estimated fair value of these awards over the requisite employee service period. On April 14, 2005, the U.S. Securities and Exchange Commission adopted a new rule amending the effective dates for SFAS 123R. In accordance with the new rule, the accounting provisions of SFAS No. 123R are effective for the Company beginning in the quarter ended March 31, 2006.

Under SFAS 123R, share-based compensation cost is measured at the grant date, based on the estimated fair value of the award, and is recognized as expense over the employee’s requisite service period. As of March 31, 2006, the Company had no unvested awards with market or performance conditions. The Company adopted the provisions of SFAS No. 123R on January 1, 2006, the first day of the Company’s fiscal year 2006, using a modified prospective application, which provides for certain changes to the method for recognizing share-based compensation. Under the modified prospective application, prior periods are not revised for comparative purposes. The provisions of SFAS No. 123R apply to new awards and to awards that are outstanding with future service periods on the effective date. Estimated compensation expense for awards outstanding with future service periods at the effective date will be recognized over the remaining service period using the compensation cost calculated for pro forma disclosure purposes under FASB Statement No. 123, “Accounting for Stock-Based Compensation” (“SFAS No. 123”).

Income Taxes

Income taxes are accounted for using the asset and liability method. Under this method, deferred income tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred income tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which these temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is provided for those deferred tax assets for which the related benefits will likely not be realized.

In determining the amount of the valuation allowance, estimated future taxable income as well as feasible tax planning strategies in each taxing jurisdiction are considered. If all or a portion of the remaining deferred tax assets will not be realized, the valuation allowance will be increased with a charge to income tax expense. Conversely, if the Company will ultimately be able to utilize all or a portion of the deferred tax assets for which a valuation allowance has been provided, the related portion of the valuation allowance will be released to income as a credit to income tax expense.

The calculation of tax liabilities involves dealing with uncertainties in the application of complex global tax regulations. The Company recognizes potential liabilities for anticipated tax audit issues in the United States and other tax jurisdictions based on its estimate of whether, and the extent to which, additional taxes will be due. If payment of these liabilities ultimately proves to be unnecessary, the reversal of the liabilities would result in tax benefits being recognized in the period when the Company determines the liabilities are no longer necessary. Additionally, the Company reviews the collectibility of its tax receivables due from various jurisdictions and when recovery is uncertain, the Company reserves amounts deemed to be uncollectible. If the receipts of these amounts occur or are assured, the reversal of the reserves previously established would result in a tax benefit in the period.

Foreign Currencies

Most of the Company’s foreign subsidiaries conduct business primarily in U.S. dollars and as a result, utilize the dollar as their functional currency. For the translation of financial statements of these subsidiaries, assets and liabilities in foreign currencies that are receivable or payable in cash are translated at current exchange rates while inventories and other non-monetary assets in foreign currencies are translated at historical rates. Gains and losses resulting from the translation of such financial statements are included in the operating results, as are gains and losses incurred on foreign currency transactions.

The Company’s remaining foreign subsidiaries utilize the local currency as their functional currency. The assets and liabilities of these subsidiaries are translated at current exchange rates while revenues and expenses are translated at the average rates in effect for the period. The related translation gains and losses are included in accumulated other comprehensive income within stockholders’ equity deficit.

Defined Benefit Plans

The Company maintains pension plans covering certain of its employees. For financial reporting purposes, net periodic pension costs are calculated based upon a number of actuarial assumptions, including a discount rate for plan obligations, assumed rate of return on pension plan assets and assumed rate of compensation increases for plan employees. All of these assumptions are based upon management’s judgment and consultation with an actuary, considering all known trends and uncertainties.

Asset Retirement Obligations

The Company recognizes asset retirement obligations (“AROs”) when incurred, with the initial measurement at fair value. These liabilities are accreted to full value over time through charges to income. In addition, asset retirement costs are capitalized as part of the related asset’s carrying value and are depreciated over the asset’s respective useful life. The weighted average discount rate used to determine the liability as of March 31, 2006 was 6.1%. The Company’s AROs consist primarily of estimated decontamination costs associated with manufacturing equipment and buildings resulting from the Company’s adoption of FIN 47, “Accounting for Conditional Asset Retirement Obligations—An Interpretation of FASB Statement No. 143” (“FIN 47”) effective December 31, 2005. As a result of the adoption of FIN 47, the Company recorded a $2.9 million net charge for the cumulative effect of accounting change in the fourth quarter of 2005.

Contingencies

The Company is involved in a variety of legal matters that arise in the normal course of business. Based on information available, management evaluates the relevant range and likelihood of potential outcomes. In accordance with SFAS No. 5, “Accounting for Contingencies”, management records the appropriate liability when the amount is deemed probable and estimable.

Note 4: Subsequent Events

Effective April 5, 2006, SCI LLC entered into an asset purchase agreement with LSI Logic Corporation (“LSI”). Under the terms of the purchase agreement, SCI LLC will purchase LSI’s Gresham, Oregon wafer fabrication facility, including real property, tangible personal property, certain intellectual property, other specified manufacturing equipment and related information. The assets to be purchased include an approximately 83 acre campus with an estimated 500,000 square feet of building space of which approximately 98,000 square feet is clean room. Pursuant to the purchase agreement, SCI LLC will offer employment to substantially all of

LSI’s manufacturing employees currently working at the Gresham facility. At the closing of the transaction, SCI LLC will enter into several ancillary agreements including, but not limited to, a wafer supply and test agreement, intellectual property license agreement, transition services agreement and facility use agreement.

The aggregate purchase price for the acquired assets is approximately $105 million. In connection with the execution of the purchase agreement, the Company paid LSI a deposit of $10.5 million. In addition, the purchase agreement obligates SCI LLC to pay $79.5 million at the closing of the transaction and the remaining balance within 90 days thereafter. The transaction is expected to close after the satisfaction or waiver of all conditions set forth in the purchase agreement, including any necessary regulatory approvals, which is expected to occur during May of 2006.

To finance a portion of the purchase, the Company completed a public offering on April 6, 2006, of common stock registered pursuant to a shelf registration statement originally filed with the Securities and Exchange Commission on January 2, 2004. In connection with this offering, the Company issued approximately 11.2 million shares (which includes 0.7 million shares issued as over-allotments) of its common stock at a price of $7.00 per share. The net proceeds from this offering received by the Company were $75.2 million after deducting the underwriting discount of $1.6 million ($0.14 per share) and offering expenses of $1.3 million.

The activity related to the Company’s restructuring, asset impairments and other, net for programs that were not completed by December 31, 2005, is as follows (in millions):

June 2005 Restructuring Program

Cumulative charges of $3.4 million have been incurred as of March 31, 2006, related to the June 2005 restructuring program. In June 2005, the Company recorded $3.4 million of employee separation charges, which included $2.2 million related to general worldwide work force reductions of approximately 60 employees. These headcount reductions were initiated for cost savings purposes. The remaining $1.2 million of employee separation charges related to the termination of 80 employees in Malaysia resulting from the transfer of wafer fabrication manufacturing operations, which supports the standard components product line, from Malaysia to the United States. As of March 31, 2006, there were 75 employees remaining to be terminated under the June 2005 restructuring program. All terminations and associated severance payments related to these charges are expected to be completed during the fourth quarter of 2006. The Company does not expect any additional charges related to the June 2005 restructuring program. A reconciliation of the beginning and ending reserve balances related to this program is as follows (in millions):

December 2003 Restructuring Program

Cumulative charges of $8.2 million offset by adjustments of $0.8 million have been incurred as of March 31, 2006, related to the December 2003 restructuring program. This includes $7.0 million of employee separation costs (partially offset by $0.7 million of adjustments) and $1.2 million of cash exit costs (partially offset by $0.1 million of adjustments).

(unaudited)

The employee separation costs of $7.0 million (partially offset by $0.7 million of adjustments) reflect the phase-out of manufacturing operations at the Company’s East Greenwich, Rhode Island facility, the shutdown of the Company’s assembly and test operations in Roznov, Czech Republic, that was announced in November 2003, and further reductions in general and administrative staffing levels in the United States and Western Europe for cost savings purposes. The employee separation charges for East Greenwich totaled $3.8 million (partially offset by $0.8 million of adjustments) for approximately 325 employees, of which $0.1 million remained unpaid for three employees remaining to be terminated as of March 31, 2006 which is expected to occur during the second quarter of 2006. The Company’s East Greenwich, Rhode Island manufacturing facility supports the Company’s Analog Product Group.

The Czech Republic employee separation charge for approximately 460 employees totaled $2.3 million (partially increased by $0.1 million of adjustments). All terminations and associated severance payments related to this charge have been completed.

The reduction in general and administrative functions in the United States and Europe totaled $0.9 million for 10 employees of which $0.1 million remained unpaid for one employee remaining to be terminated as of March 31, 2006. This termination and associated severance payments are expected to be completed by the fourth quarter of 2006.

The cash exit costs of $1.2 million (partially offset by $0.1 million of adjustments) include lease and contract termination costs incurred in connection with the consolidation of sales, distribution and administrative facilities in North America as well as charges related to certain exit activities that were completed in connection with the shutdown of manufacturing operations in East Greenwich, Rhode Island. All associated payments related to these exit costs have been completed.

The Company does not expect any additional charges related to the December 2003 restructuring program. A reconciliation of the beginning and ending reserve balances related to this program is as follows (in millions):

December 2002 Restructuring Program

Cumulative charges since 2002 of $11.9 million, offset by adjustments of $2.0 million, have been incurred through March 31, 2006, related to the December 2002 restructuring program. This includes $10.1 million for employee separation costs (partially offset by $2.0 million of adjustments) relating to the termination of approximately 300 employees and approximately $1.8 million in expected lease termination and other exit costs associated with the decommissioning of certain assets. The headcount reductions began in the first quarter of 2003 and impacted both manufacturing and non-manufacturing personnel mainly in the United States. These headcount reductions were initiated for cost savings purposes. The $2.0 million of adjustments were primarily made for employees whose terminations were rescinded due to business improvements and the plan to consolidate accounting systems. As of March 31, 2006, there were 5 employees remaining to be terminated during 2006, and the related unpaid severance payments of $0.2 million are expected to be settled by June 2006.

March 2002 Restructuring Program

Cumulative charges of $7.2 million and additional charges from adjustments of $0.5 million have been incurred as of March 31, 2006, related to the March 2002 restructuring program. This includes approximately $5.0 million attributable to employee terminations resulting from the Company’s decision to relocate its European administrative functions from Toulouse, France to Roznov, Czech Republic and Piestany, Slovakia for cost savings purposes. The relocation of these functions was completed in 2003. The remaining $2.2 million related to reductions in selling, general and administrative personnel primarily in the U.S, which included $0.2 million of non-cash employee stock compensation expense associated with the modification of stock options for certain terminated employees. Subsequent to March 2002, the Company recorded an additional $0.5 million in employee separation costs relating to the relocation of the administrative functions in Toulouse, France based on the Company’s estimate of costs to complete the activity at the times the adjustments were recorded. As of December 31, 2005, all employees had been terminated under this program and the remaining liability relating to this restructuring of $0.2 million as of March 31, 2006 is expected to be paid by December 2006. The Company does not expect any additional charges related to the March 2002 restructuring program.

(1) The term loan portion of the Company’s credit facility matures December 15, 2009. However, if the first date on which holders of at least $210.0 million in aggregate principal amount of the Company’s zero coupon convertible senior subordinated notes due 2024 can exercise their “put” right is extended (currently April 10, 2010), the term loan will mature six months prior to such date.

February 2006 Amendment to Senior Bank Facilities

In February 2006, the Company refinanced the term loans under its senior bank facilities to reduce the interest rate from LIBOR plus 2.75% to LIBOR plus 2.50%. The amended and restated credit agreement also provided for a step down provision that reduced the interest rate to LIBOR plus 2.25% since the Company maintained a specified credit rating and meets the specified leverage ratio test based on the Company’s 2005 results.

March 2006 Amendment to Senior Bank Facilities

The credit agreement relating to the Company’s senior bank facilities includes a provision requiring an annual calculation of cash flow (as defined in the credit agreement) and the application of a portion of that cash flow as a prepayment of loans outstanding under the agreement. In March 2006, the Company obtained an amendment to this provision of the credit agreement, which requires prepayment only at the election of the debt holders. As a result of this amendment, only $0.1 million of the $26.0 million classified as a current maturity as of December 31, 2005 was paid at the election of the debt holders during the first quarter of 2006. Therefore, the remaining $25.9 million was reclassified to long-term debt as of March 31, 2006.

Debt Guarantees

The Company is the sole issuer of the zero coupon convertible senior subordinated notes due 2025 and the 1.875% convertible senior subordinated notes due 2024 (collectively, “the Notes”). The Company’s domestic subsidiaries (collectively, the “Guarantor Subsidiaries”) fully and unconditionally guarantee on a joint and several basis the Company’s obligations under the Notes. The Guarantor Subsidiaries include SCI LLC, Semiconductor Components Industries of Rhode Island, Inc, an operating subsidiary, as well as holding companies whose net assets consist primarily of investments in the joint venture in Leshan, China and nominal equity interests in certain of the Company’s other foreign subsidiaries. The Company’s remaining subsidiaries (collectively, the “Non-Guarantor Subsidiaries”) are not guarantors of the Notes.

Note 8: Common Stock

On April 6, 2006, the Company completed a public offering of common stock registered pursuant to a shelf registration statement originally filed with the Securities and Exchange Commission on January 2, 2004. In connection with this offering, the Company issued approximately 11.2 million shares (which includes 0.7 million shares issued as over-allotments) at a price of $7.00 per share. The net proceeds from this offering received by the Company were $75.2 million after deducting the underwriting discount of $1.6 million ($0.14 per share) and offering expenses of $1.3 million. The Company intends to use the net proceeds to partially fund the purchase of LSI’s Gresham wafer fabrication facility, which has a total purchase price of $105 million. See further discussion in Note 4: Subsequent Events.

Income per share calculations for the quarter ended March 31, 2006 and April 1, 2005, are as follows (in millions, except per share data):

	Quarter Ended
	March 31, 2006		April 1, 2005

Income per common share
Basic:	$	0.13	$	0.04
Diluted:	$	0.12	$	0.04

Basic income per share is computed by dividing net income, adjusted for the accretion to redemption value and dividends related to the Company’s preferred stock during the periods they were outstanding, by the weighted average number of common shares outstanding during the period. In periods in which the Company generated income when the preferred stock was outstanding, the two-class method was used to calculate basic earnings per share whereby net income, adjusted for the accretion to redemption value and dividends related to the Company’s preferred stock, is allocated on a pro-rata basis between common and preferred stockholders, as required by Emerging Issues Task Force (“EITF”) Issue 03-6, due to the preferred stockholders’ right to participate in dividends declared on the Company’s common stock.

Diluted income per share generally would assume the conversion of the preferred stock into common stock if dilutive and also incorporates the incremental impact of shares issuable upon the assumed exercise of stock options and upon the assumed conversion of the zero coupon convertible senior subordinated notes. However, since basic earnings per share under the two-class method is lowered due to the allocation of undistributed earnings to preferred stockholders in periods the preferred stock was outstanding, the impact to diluted earnings per share of the assumed conversion of the convertible redeemable preferred stock into common stock is anti-dilutive, and therefore is excluded from the calculation of diluted earnings per share.

The number of incremental shares from the assumed exercise of stock options is calculated by applying the treasury stock method. Common shares relating to the employee stock options where the exercise price exceeded the average market price of the Company’s common shares or the assumed exercise would have been anti-dilutive during these periods were also excluded from the diluted earnings per share calculation. The excluded options were 8.7 million and 15.3 million for the quarter ended March 31, 2006 and April 1, 2005, respectively.

For the quarter ended March 31, 2006, the assumed conversion of the 1.875% convertible senior subordinated notes was included in determining diluted earnings per share. The 1.875% convertible senior subordinated notes are convertible into cash up to the par value of $95.0 million, based on an initial conversion price of approximately $7.00 per share. The excess of fair value over par value is convertible into stock. As of March 31, 2006, the closing price of the Company’s common stock was $7.26; thus, the effects of an assumed net share settlement would have been dilutive and therefore were included.

For the assumed conversion of the zero coupon convertible senior subordinated notes, $0.4 million of amortization expense of debt issuance costs for the quarters ended March 31, 2006 and April 1, 2005 was added back to net income to calculate diluted earnings per share.

Note 9: Employee Stock Benefit Plans

Employee Stock Options

The Company adopted the ON Semiconductor 1999 Founders Stock Option Plan (“the 1999 Plan”), which is an incentive plan for key employees, directors and consultants. A total of 11.6 million shares of the Company’s common stock have been reserved for issuance under the 1999 Plan. The 1999 Plan is administered by the Board of Directors or a committee thereof, which is authorized to, among other things, select the key employees, directors and consultants who will receive grants and determine the exercise prices and vesting schedules of the options. Prior to the existence of a public market for the Company’s common stock, the Board of Directors determined fair market value of the share based payment awards to be granted under the 1999 Plan.

On February 17, 2000, the Company adopted the 2000 Stock Incentive Plan (“the 2000 Plan”) which provides key employees, directors and consultants with various equity-based incentives as described in the plan document. The 2000 Plan is administered by the Board of Directors or a committee thereof, which is authorized to determine, among other things, the key employees, directors or consultants who will receive awards under the plan, the amount and type of award, exercise prices or performance criteria, if applicable, and vesting schedules. Through December 31, 2004, stockholders had approved amendments to the 2000 Plan which have increased the number of shares of the Company’s common stock reserved and available for grant to 30.5 million, plus an additional number of shares of the Company’s common stock equal to 3% of the total number of outstanding shares of common stock effective automatically on January 1st of each year beginning January 1, 2005 and ending January 1, 2010. As of January 1, 2006 and 2005, the number of shares of the Company’s common stock reserved and available for grant increased by 9.3 million and 7.7 million, respectively to 47.5 million and

21

ON SEMICONDUCTOR CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

(unaudited)

38.2 million, from 30.5 million shares as of December 31, 2004, in accordance with the approved amendments. The 2000 Plan has also been amended to increase the maximum number of options granted to any one participant during a fiscal year from 1.0 million shares to 2.5 million, and to allow the Board of Directors to adopt a program of exchanging underwater options for newly issued options.

Generally, the options granted under both plans vest over a period of four years and have a term of 10 years. Under the 1999 Plan, all outstanding options and under the 2000 Plan certain outstanding options vest automatically upon a change of control, as defined, provided the option holder is employed by the Company on the date of the change in control. Under the 2000 Plan, certain other outstanding options vest upon a change of control if the Board of Directors of the Company, at its discretion, provides for acceleration of the vesting of said options. Upon the termination of an option holder’s employment, all unvested options will immediately terminate and vested options will generally remain exercisable for a period of 90 days after date of termination (one year in the case of death or disability), unless otherwise specified in an option holder’s employment or stock option agreement.

There was an aggregate of 19.0 million and 13.6 million shares of common stock available for grant under both plans at March 31, 2006 and December 31, 2005, respectively.

Share-Based Compensation Information under SFAS No. 123R

The fair value of each option grant in 2005 and thereafter is estimated on the date of grant using a lattice-based option valuation model. In past years, the Company has used the Black-Scholes option-pricing model to calculate the fair value of its options. The lattice model uses: 1) an implied volatility curve derived from Heston’s stochastic volatility model and calibrated using a regression analysis instead of a single volatility assumption as used in the Black-Scholes model; 2) an employee exercise behavior model (based on an analysis of historical exercise behavior); and 3) the treasury yield curve to calculate the fair value of each option grant.

The weighted-average estimated fair value of employee stock options granted during the quarter ended March 31, 2006 was $2.97 per share and was calculated using the lattice model with the following weighted-average assumptions (annualized percentages):

	Quarter Ended March 31, 2006
Volatility	49.0	%
Risk-free interest rate	4.7	%
Post-vesting forfeiture rate	9.3	%
Rate of exercise	28.6	%

The Company used implied volatility of market-traded options of the Company’s stock exclusively for the expected volatility assumption input to the lattice model. The risk-free interest rate assumption is based upon observed interest rates appropriate for the expected life of the Company’s employee stock options. The Company has historically not declared dividends, thus the dividend yield was assumed to be zero in the lattice model. The post-vesting forfeiture rate and rate of exercise factor are based on the Company’s historical option cancellation and employee exercise information, respectively. The rate of exercise indicates the annual rate at which vested, in-the-money options have historically been exercised early.

The expected life of employee stock options represents the weighted-average period the stock options are expected to remain outstanding and is a derived output of the lattice model. The expected life of employee stock options is impacted by all of the underlying assumptions used in the Company’s model. The lattice model

22

ON SEMICONDUCTOR CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

(unaudited)

assumes that employees’ exercise behavior is a function of the option’s remaining contractual life and the extent to which the option is in-the-money (i.e., the average stock price during the period is above the strike price of the stock option). The lattice model estimates the probability of exercise as a function of these two variables based on the history of exercises and cancellations on past option grants made by the Company. The expected life for options granted during the quarter ended March 31, 2006 derived from the lattice model was 4.0 years.

In the Company’s pro forma information required under SFAS No. 123 for the periods prior to fiscal 2006, the Company accounted for forfeitures as they occurred. Share-based compensation expense recognized in the Consolidated Statement of Operations for the first quarter of fiscal year 2006 is based on awards ultimately expected to vest. SFAS 123R requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Pre-vesting forfeitures were estimated to be approximately 16% in the first quarter of fiscal year 2006 based on historical experience.

The Company continues to use the Black-Scholes option-pricing model to calculate the fair value of shares issued under the 2000 Employee Stock Purchase Plan. The weighted-average fair value of shares issued under the Employee Stock Purchase Plan during the quarter ended March 31, 2006 was $1.33. The weighted-average assumptions used in the pricing model are as follows:

Employee Stock Purchase Plan	Quarter Ended March 31, 2006
Expected life (in years)	0.25
Risk-free interest rate	4.16	%
Volatility	44.00	%

Total estimated share-based compensation expense, related to all of the Company’s share-based awards, recognized for the quarter ended March 31, 2006 was comprised as follows (in millions, except per share data):

	Quarter Ended March 31, 2006
Cost of revenues	$	0.4
Research and development		0.3
Selling and marketing		0.5
General and administrative		0.7
Share-based compensation expense before income taxes		1.9
Related income tax benefits (1)		—
Share-based compensation expense, net of taxes	$	1.9
Net share-based compensation expense, per common share:
Basic	$	0.01
Diluted	$	0.01

(1) Most of the Company’s share-based compensation relates to its domestic subsidiaries which have historically experienced recurring net operating losses; therefore, no related income tax benefits are expected.

The Company recorded $0.4 million in share-based compensation expense during the quarter ended March 31, 2006 related to share-based awards granted during the first quarter of 2006. This included expense related to the Employee Stock Purchase Plan of $0.2 million and an immaterial amount of expense related to

restricted stock units awarded to certain members of the Company’s Board of Directors. The remaining expense of $1.5 million related to share-based awards granted prior to December 31, 2005.

Pro Forma Information under SFAS No. 123 for the quarter ended April 1, 2005

Prior to adopting the provisions of SFAS No. 123R, the Company recorded estimated compensation expense for employee stock options based upon their intrinsic value on the date of grant pursuant to Accounting Principles Board Opinion 25 (APB 25), “Accounting for Stock Issued to Employees” and provided the required pro forma disclosures of SFAS No. 123. Because the Company established the exercise price based on the fair market value of the Company’s stock at the date of grant, the stock options had no intrinsic value upon grant, and therefore no estimated expense was recorded prior to adopting SFAS No. 123R.

For purposes of pro forma disclosures under SFAS No. 123 for the quarter ended April 1, 2005, the estimated fair value of the stock options was assumed to be amortized to expense over the stock options’ vesting periods. The pro forma effects of recognizing estimated compensation expense under the fair value method on net income and earnings per common share for the quarter ended April 1, 2005 were as follows (in millions, except per share data):

	Quarter Ended April 1, 2005
Net income, as reported	$	14.8
Add: Stock-based employee compensation expense included in reported net income, net of related tax effects		—
Less: Total stock-based employee compensation expense determined under the fair value based method for all awards, net of related tax effects		(3.6	)

The fair value of option grants during the respective period was estimated at the date of grant while the fair value of the shares issued under the ON Semiconductor 2000 Employee Stock Purchase Plan was estimated at the beginning of the respective offering periods. The weighted-average Black-Scholes equivalent assumptions for the quarter ended April 1, 2005, for employee stock options are detailed below:

Employee Stock Options	Quarter Ended April 1, 2005
Expected life (in years)	3.81

The fair value of the Employee Stock Purchase Plan shares issued during the quarter ended April 1, 2005 has been calculated using the Black-Scholes option-pricing model with the weighted-average assumptions detailed below:

Employee Stock Purchase Plan	Quarter Ended April 1, 2005
Expected life (in years)	0.25
Risk-free interest rate	2.22	%
Volatility	58.0	%

The weighted-average estimated fair value of employee stock options granted during the quarter ended April 1, 2005 was $2.25 per share. The weighted-average estimated fair value of the shares issued under the 2000 Employee Stock Purchase Plan during the quarter ended April 1, 2005 was $1.13.

A summary of stock option transactions for all stock option plans follows (in millions except per share and term data):

	Quarter Ended March 31, 2006
	Number of Shares		Weighted- Average Exercise Price		Weighted- Average Remaining Contractual Term (in years)	Aggregate Intrinsic Value (In-The- Money Options)

Exercisable at March 31, 2006	17.2		$	5.28	6.08	$	47.2

Net stock options, after forfeitures and cancellations, granted during the quarter ended March 31, 2006 and April 1, 2005 represented 1.2% and 1.8% of outstanding shares as of the beginning of each such fiscal quarter, respectively. Total stock options granted during the quarter ended March 31, 2006 and April 1, 2005 represented 1.4% and 2.0% of outstanding shares as of the end of each such fiscal quarter, respectively.

At March 31, 2006, total unrecognized estimated compensation cost related to non-vested stock options granted prior to that date was $20.8 million, which is expected to be recognized over a weighted average period of 3.1 years. The total share-based compensation cost of stock options capitalized as part of inventory was negligible as of March 31, 2006. The total intrinsic value of stock options exercised during the quarter ended March 31, 2006 was $7.1 million. The Company recorded cash received from the exercise of stock options of $5.2 million and cash from issuance of shares under the Employee Stock Purchase Plan of $0.5 million and no related tax benefits during the quarter ended March 31, 2006. Upon option exercise or completion of a purchase under the Employee Stock Purchase Plan the Company issues new shares of stock.

Restricted Stock Units

The Company’s stock compensation plan permits the granting of restricted stock units to eligible employees and non-employee directors at fair market value at the date of the grant. Restricted stock units are payable in shares of the Company’s stock upon vesting. The following table presents a summary of the status of the Company’s nonvested restricted stock units as of March 31, 2006, and changes during the quarter ended March 31, 2006.

Vested	—		—
Forfeited	—		—
Nonvested shares of restricted stock units at March 31, 2006	0.1	$	6.83

As of March 31, 2006, there was approximately $0.5 million of total unrecognized compensation cost related to nonvested restricted stock units granted under the plan. The cost is expected to be recognized over the vesting period. Compensation expense related to restricted stock units was immaterial for the quarter ended March 31, 2006. As of March 31, 2006, the Company had approximately 0.1 million restricted stock units outstanding.

Employee Stock Purchase Plans

On February 17, 2000, the Company adopted the 2000 Employee Stock Purchase Plan. Subject to local legal requirements, each of the Company’s eligible employees has the right to elect to have up to 10% of their payroll applied towards the purchase of shares of the Company’s common stock at a price equal to 85% of the fair market value of such shares as determined under the plan. Employees are limited to annual purchases of $25,000 under this plan. In addition, during each quarterly offering period, employees may not purchase stock exceeding the lesser of (i) 500 shares, or (ii) the number of shares equal to $6,250 divided by the fair market value of the stock on the first day of the offering period. During the quarter ended March 31, 2006 and the quarter ended April 1, 2005, employees purchased approximately 0.1 million and 0.1 million shares under the plan,

26

respectively. Through December 31, 2004, shareholders have approved amendments to the 2000 Employee Stock Purchase Plan which have increased the number of shares of the Company’s common stock issuable thereunder to 8.5 million shares. As of March 31, 2006, there were 3.4 million shares available for issuance under the Employee Stock Purchase Plan.

Note 10: Commitments and Contingencies

Leases

The following is a schedule by year of future minimum lease obligations under non-cancelable operating leases as of March 31, 2006 (in millions):

Remainder of 2006 (1)	$	4.9

Thereafter		1.8
Total	$	14.6

(1) Minimum payments have not been reduced by minimum sublease rentals of $0.7 million due in the future under subleases. Minimum payments include the interest portion of payments for capital lease obligations.

Other Contingencies

The Company’s manufacturing facility in Phoenix, Arizona is located on property that is a “Superfund” site, a property listed on the National Priorities List and subject to clean-up activities under the Comprehensive Environmental Response, Compensation, and Liability Act. Motorola is actively involved in the cleanup of on-site solvent contaminated soil and groundwater and off-site contaminated groundwater pursuant to consent decrees with the State of Arizona. As part of the August 4, 1999 recapitalization, Motorola has retained responsibility for this contamination, and has agreed to indemnify the Company with respect to remediation costs and other costs or liabilities related to this matter.

Manufacturing facilities in Slovakia and in the Czech Republic have ongoing remediation projects to respond to releases of hazardous substances that occurred during the years that these facilities were operated by government-owned entities. In each case, these remediation projects consist primarily of monitoring groundwater wells located on-site and off-site with additional action plans developed to respond in the event activity levels are exceeded at each of the respective locations. The governments of the Czech Republic and Slovakia have agreed to indemnify the Company and the respective subsidiaries, subject to specified limitations, for remediation costs associated with this historical contamination. Based upon the information available, total future remediation costs to the Company are not expected to be material.

The Company’s facility in East Greenwich, Rhode Island has adjoining property that has localized soil contamination. In connection with the purchase of the facility, the Company entered into a Settlement Agreement and Covenant Not To Sue with the State of Rhode Island. This agreement requires that remedial actions be undertaken and a quarterly groundwater monitoring program be initiated by the former owners of the property. Based on the information available, any costs to the Company in connection with this matter are not expected to be material.

Indemnification Contingencies

The Company is a party to a variety of agreements entered into in the ordinary course of business pursuant to which it may be obligated to indemnify the other parties for certain liabilities that arise out of or relate to the subject matter of the agreements. Some of the agreements entered into by the Company require it to indemnify the other party against losses due to intellectual property infringement, property damage including environmental contamination, personal injury, failure to comply with applicable laws, the Company’s negligence or willful misconduct, or breach of representations and warranties and covenants related to such matters as title to sold assets.

The Company is a party to various agreements with Motorola which were entered into in connection with the Company’s separation from Motorola. Pursuant to these agreements, the Company has agreed to indemnify Motorola for losses due to, for example, breach of representations and warranties and covenants, damages arising from assumed liabilities or relating to allocated assets, and for specified environmental matters. The Company’s obligations under these agreements may be limited in terms of time and/or amount and payment by the Company is conditioned on Motorola making a claim pursuant to the procedures specified in the particular contract, which procedures typically allow the Company to challenge Motorola’s claims.

The Company and its subsidiaries provide for indemnification of directors, officers and other persons in accordance with limited liability agreements, certificates of incorporation, by-laws, articles of association or similar organizational documents, as the case may be. The Company maintains directors’ and officers’ insurance, which should enable it to recover a portion of any future amounts paid.

In addition to the above, from time to time the Company provides standard representations and warranties to counterparties in contracts in connection with sales of its securities and the engagement of financial advisors and also provides indemnities that protect the counterparties to these contracts in the event they suffer damages as a result of a breach of such representations and warranties or in certain other circumstances relating to the sale of securities or their engagement by the Company.

While the Company’s future obligations under certain agreements may contain limitations on liability for indemnification, other agreements do not contain such limitations and under such agreements it is not possible to predict the maximum potential amount of future payments due to the conditional nature of the Company’s obligations and the unique facts and circumstances involved in each particular agreement. Historically, payments made by the Company under any of these indemnities have not had a material effect on the Company’s business, financial condition, results of operations or cash flows. Additionally, the Company does not believe that any amounts that it may be required to pay under these indemnities in the future will be material to the Company’s business, financial condition, results of operations or cash flows.

Legal Matters

The Company is currently involved in a variety of legal matters that arise in the normal course of business. Based on information currently available, management does not believe that the ultimate resolution of these matters, including the matters described in the next paragraphs, will have a material adverse effect on the Company’s financial condition, results of operations or cash flows. However, because of the nature and inherent uncertainties of litigation, should the outcome of these actions be unfavorable, the Company’s business, financial condition, results of operations or cash flows could be materially and adversely affected.

Securities Class Action Litigation.    During the period July 5, 2001 through July 27, 2001, the Company was named as a defendant in three shareholder class action lawsuits that were filed in federal court in New York

28

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

(unaudited)

City against the Company and certain of its former officers, current and former directors and the underwriters for its initial public offering. The lawsuits allege violations of the federal securities laws and have been docketed in the U.S. District Court for the Southern District of New York as: Abrams v. ON Semiconductor Corp., et al., C.A. No. 01-CV-6114; Breuer v. ON Semiconductor Corp., et al., C.A. No. 01-CV-6287; and Cohen v. ON Semiconductor Corp., et al., C.A. No. 01-CV-6942. On April 19, 2002, the plaintiffs filed a single consolidated amended complaint that supersedes the individual complaints originally filed. The amended complaint alleges, among other things, that the underwriters of the Company’s initial public offering improperly required their customers to pay the underwriters’ excessive commissions and to agree to buy additional shares of the Company’s common stock in the aftermarket as conditions of receiving shares in the Company’s initial public offering. The amended complaint further alleges that these supposed practices of the underwriters should have been disclosed in the Company’s initial public offering prospectus and registration statement. The amended complaint alleges violations of both the registration and antifraud provisions of the federal securities laws and seeks unspecified damages. Management understands that various other plaintiffs have filed substantially similar class action cases against approximately 300 other publicly-traded companies and their public offering underwriters in New York City, which have all been transferred, along with the case against the Company, to a single federal district judge for purposes of coordinated case management. The Company believes that the claims against it are without merit and have defended, and intend to continue to defend, the litigation vigorously. The litigation process is inherently uncertain, however, and the Company cannot guarantee that the outcome of these claims will be favorable for it.

On July 15, 2002, together with the other issuer defendants, the Company filed a collective motion to dismiss the consolidated, amended complaints against the issuers on various legal grounds common to all or most of the issuer defendants. The underwriters also filed separate motions to dismiss the claims against them. In addition, the parties have stipulated to the voluntary dismissal without prejudice of the Company’s individual former officers and current and former directors who were named as defendants in the Company’s litigation, and they are no longer parties to the litigation. On February 19, 2003, the Court issued its ruling on the motions to dismiss filed by the underwriter and issuer defendants. In that ruling the Court granted in part and denied in part those motions. As to the claims brought against the Company under the antifraud provisions of the securities laws, the Court dismissed all of these claims with prejudice, and refused to allow plaintiffs the opportunity to re-plead these claims. As to the claims brought under the registration provisions of the securities laws, which do not require that intent to defraud be pleaded, the Court denied the motion to dismiss these claims as to the Company and as to substantially all of the other issuer defendants as well. The Court also denied the underwriter defendants’ motion to dismiss in all respects.

In June 2003, upon the determination of a special independent committee of the Company’s Board of Directors, the Company elected to participate in a proposed settlement with the plaintiffs in this litigation. If ultimately approved by the Court, this proposed settlement would result in the dismissal, with prejudice, of all claims in the litigation against the Company and against any of the other issuer defendants who elect to participate in the proposed settlement, together with the current or former officers and directors of participating issuers who were named as individual defendants. The proposed settlement does not provide for the resolution of any claims against the underwriter defendants, and the litigation against those defendants is continuing. The proposed settlement provides that the class members in the class action cases brought against the participating issuer defendants will be guaranteed a recovery of $1 billion by the participating issuer defendants. If recoveries totaling less than $1 billion are obtained by the class members from the underwriter defendants, the class members will be entitled to recover the difference between $1 billion and the aggregate amount of those recoveries from the participating issuer defendants. If recoveries totaling $1 billion or more are obtained by the class members from the underwriter defendants, however, the monetary obligations to the class members under

29

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

(unaudited)

the proposed settlement will be satisfied. In addition, the Company and any other participating issuer defendants will be required to assign to the class members certain claims that the Company may have against the underwriters of the Company’s initial public offerings.

The proposed settlement contemplates that any amounts necessary to fund the settlement or settlement-related expenses would come from participating issuers’ directors and officers’ liability insurance policy proceeds, as opposed to funds of the participating issuer defendants themselves. A participating issuer defendant could be required to contribute to the costs of the settlement if that issuer’s insurance coverage were insufficient to pay that issuer’s allocable share of the settlement costs. The Company expects that its insurance proceeds will be sufficient for these purposes and that the Company will not otherwise be required to contribute to the proposed settlement.

Consummation of the proposed settlement is conditioned upon obtaining approval by the Court. On September 1, 2005, the Court preliminarily approved the proposed settlement and directed that notice of the terms of the proposed settlement be provided to class members. Thereafter, the Court held a fairness hearing on April 24, 2006, at which objections to the proposed settlement were heard. After the fairness hearing, the Court took under advisement whether to grant final approval to the proposed settlement.

If the proposed settlement described above is not consummated, the Company intends to continue to defend the litigation vigorously. While the Company can make no promises or guarantees as to the outcome of these proceedings, the Company believes that the final result of these actions will have no material effect on its consolidated financial condition, results of operations or cash flows.

AMS Matter.    On March 22, 2005, the Company entered into a settlement agreement with Austriamicrosystems, AG (“AMS”) regarding a pending lawsuit. Under the settlement agreement the Company paid AMS $2.4 million in cash upon the signing of the agreement. The Company had previously reserved $2.5 million as a reasonable loss estimate of the loss exposure for this matter. The settlement agreement includes, among other things, a full and complete mutual release of any and all claims, except for any claims arising out of the arbitration described below. It also provides that the pending litigation will be dismissed with prejudice and each party will bear its own costs and fees incurred in connection with the litigation. The dismissal occurred shortly after the signing of the agreement. The settlement agreement requires that the Company and AMS enter into final, binding and non-appealable arbitration limited to one unresolved issue associated with the litigation. The arbitration was held on April 12 through April 14, 2006 and the Company is currently awaiting a ruling by the arbitrator. If the arbitrator rules in favor of AMS, the Company will pay an additional $2.2 million within fifteen days of the ruling by the arbitrator. If the arbitrator rules in favor of the Company, AMS will not be entitled to any additional amounts of money from the Company. On April 27, 2006, the arbitrator ruled in the Company’s favor. As a result of this ruling, AMS is entitled to no money from the Company regarding this issue. Each party shall bear its own costs and fees incurred in connection with the arbitration, and the parties will each pay fifty percent of the costs and fees of the arbitrator.

The matter originated out of an action filed in October 2003 in Arizona Superior Court by AMS against the Company. The complaint (i) alleged that the Company breached a foundry agreement entered into in 2000 under which AMS was to provide services to the Company, and (ii) claimed tortious interference with contract. The complaint sought approximately $5.8 million in contract damages, plus interest, costs, attorneys’ fees and exemplary damages.

Note 11: Related Party Transactions

As described in Note 1: Background and Basis of Presentation, on August 4, 1999, certain related transactions were effected pursuant to an agreement among the Company, SCI LLC and TPG. As of March 31, 2006, TPG owned approximately 53% of the Company’s outstanding shares of common stock.

In connection with the amendment to the Company’s senior bank facilities in August 2001, any management fees payable to TPG or its affiliates by the Company will not accrue and not be payable in cash until the Company’s quarterly financial statements demonstrate that certain financial ratios have been achieved. TPG subsequently agreed that these fees will not accrue during the period in which the Company was not permitted to pay such fees in cash. During 2004, no TPG management fee was paid or accrued. During the fourth quarter of 2004, the Company met the requisite conditions under its amended debt agreements to allow for such annual management fee to resume. However, no services were performed by TPG during the fourth quarter of 2004, and accordingly no annual management fees were accrued for or paid during the year. During the first quarter of 2005, TPG waived the right to any future management fee subject to the Company paying certain costs and expenses associated with a resale shelf registration statement of the Company’s common stock presently owned by TPG.

Note 12: Recent Accounting Pronouncements

In September 2005, the Emerging Issues Task Force reached consensus on EITF Issue No. 04-13, “Accounting for Purchases and Sales of Inventory with the Same Counterparty” (“Issue No. 04-13). In certain situations, a company may enter into nonmonetary transactions to sell inventory to another company in the same line of business from which it also purchases inventory. Under Issue No. 04-13, in general, an entity is required to treat sales and purchases of inventory between the entity and the same counterparty as one transaction for purposes of applying APB Opinion No. 29, “Accounting for Nonmonetary Transactions” when such transactions are entered into in contemplation of each other. When such transactions are legally contingent on each other, they are considered to have been entered into in contemplation of each other. The EITF also agreed on other factors that should be considered in determining whether transactions have been entered into in contemplation of each other. Issue No. 04-13 will be effective for all new arrangements entered into in reporting periods beginning after March 15, 2006. The Company’s adoption of the provisions of Issue No. 04-13 are not expected to impact its financial condition or results of operations.

In February of 2006, the FASB issued SFAS No. 155, “Accounting for Certain Hybrid Instruments—An Amendment of FASB Statements No. 133 and No. 144” (“SFAS No. 155”). SFAS No. 155 permits fair value remeasurement for any hybrid financial instrument that contains an embedded derivative that otherwise would require bifurcation. It also clarifies which interest-only strips and principal-only strips are not subject to the requirements of FASB Statement No. 133, and establishes a requirement to evaluate interests in securitized financial assets to identify interests that are freestanding derivatives or that are hybrid financial instruments that contain an embedded derivative requiring bifurcation. Furthermore, SFAS No. 155 clarifies that concentrations of credit risk in the form of subordination are not embedded derivatives and it amends FASB Statement No. 140 to eliminate the prohibition on a qualifying special purpose entity from holding a derivative financial instrument that pertains to a beneficial interest other than another derivative financial instrument. SFAS No. 155 is effective for all financial instruments acquired or issued after the beginning of the first fiscal year beginning after September 15, 2006. The Company’s adoption of the provisions of SFAS No. 155 is not expected to impact its financial condition or results of operations.

Note 13: Segment Information

The Company is engaged in the design, development, manufacture and marketing of a wide variety of semiconductor components. The Company has four main product lines: power management and standard analog devices, metal oxide semiconductor (MOS) power devices, high frequency clock and data management devices and standard components.

The Company’s reportable segments are aligned internally as the Integrated Power Group and the Analog Products Group. These segments represent management’s view of the Company’s businesses and inform how it evaluates the progress of its major components. The power management and standard analog product line as well as the high frequency clock and data management product line are aligned under the Analog Products Group, while the MOS power devices product line and the standard components product line are aligned under the Integrated Power Group. The standard logic product unit, however, whose results are included in our Analog Products Group segment, is part of our standard components product line. The standard logic product unit had revenues of approximately $32.1 million and $22.1 million in the quarter ended March 31, 2006 and in the quarter ended April 1, 2005, respectively.

The accounting policies of the segments are the same as those described in the summary of significant accounting policies. The Company does not specifically identify and allocate any assets by operating segment. The Company evaluates performance based on income or loss from operations before interest, nonrecurring gains and losses, foreign exchange gains and losses, income taxes and certain other unallocated expenses.

The Company’s wafer manufacturing facilities fabricate integrated circuits for all business units as necessary and their operating costs are reflected in the segments’ cost of revenues on the basis of product costs. Because operating segments are generally defined by the products they design and sell, they do not make sales to each other. The Company does not discretely allocate assets to its operating segments, nor does management evaluate operating segments using discrete asset information.

In addition to the operating segments mentioned above, the Company also operates global operations, sales and marketing, information systems, finance and administration groups that are led by vice presidents who report to the Chief Executive Officer. The expenses of these groups are allocated to the operating segments based on specific and general criteria and are included in the operating results reported below. The aggregate amount of the Company’s goodwill balance of $77.3 million as of March 31, 2006 and December 31, 2005 relates to the Analog Products Group. The Company does not allocate income taxes or interest expense to its operating segments as the operating segments are principally evaluated on operating profit before interest and taxes. Additionally, restructuring, asset impairments and other, net and certain other manufacturing and operating expenses, which include corporate research and development costs, inventory reserves and miscellaneous nonrecurring expenses, are not allocated to any product segment.

Information about segments for the quarters ended March 31, 2006 and April 1, 2005 are as follows, in millions:

	Integrated Power Group		Analog Products Group		Total
Quarter ended March 31, 2006:

The Company operates in various geographic locations. Sales to unaffiliated customers have little correlation with the location of manufacturers. It is, therefore, not meaningful to present operating profit by geographic location. The Company conducts a substantial portion of its operations outside of the United States and is subject to risks associated with non-U.S. operations, such as political risks, currency controls and fluctuations, tariffs, import controls and air transportation.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

You should read the following discussion in conjunction with our audited historical consolidated financial statements, which are included in our Form 10-K, filed with the SEC on February 22, 2006. Management’s Discussion and Analysis of Financial Condition and Results of Operations contains statements that are forward-looking. These statements are based on current expectations and assumptions that are subject to risk, uncertainties and other factors. Actual results could differ materially because of certain factors discussed below or elsewhere in this Form 10-Q.

Executive Overview

This section presents summary information regarding our industry, markets and operating trends only. For further information regarding the events summarized herein, you should read “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in its entirety.

Industry Overview

We participate in unit and revenue surveys and use data summarized by the World Semiconductor Trade Statistics (“WSTS”) group to evaluate overall semiconductor market trends and also to track our progress against the total market in the areas we provide semiconductor components. The most recently published estimates of WSTS project a compound annual growth rate in our total addressable market of approximately 8% during 2006 through 2008. These are projections and may not be indicative of actual results. Other industry data also indicate that the market for our products has begun to expand after the recent and prolonged downturn.

Business and Company Overview

We classify our products broadly as power and data management semiconductors and standard semiconductor components. We design, manufacture and market an extensive portfolio of semiconductor components that addresses the design needs of sophisticated electronic systems and products. Our power management semiconductor components control, convert, protect and monitor the supply of power to the different elements within a wide variety of electronic devices. Our data management semiconductor components provide high-performance clock management and data flow management for precision computing and communications systems. Our standard semiconductor components serve as “building block” components within virtually all electronic devices. These various products fall into the logic, analog and discrete categories used by WSTS.

We serve a broad base of end-user markets, including computing, automotive electronics, consumer electronics, industrial electronics, wireless communications and networking. Applications for our products in these markets include portable electronics, computers, game stations, servers, automotive and industrial automation control systems, routers, switches, storage-area networks and automated test equipment.

We have four main product lines: power management and standard analog devices, metal oxide semiconductor (“MOS”) power devices, high frequency clock and data management devices and standard components. Our extensive portfolio of devices enables us to offer advanced integrated circuits and the “building block” components that deliver system level functionality and design solutions. Our product portfolio currently comprises approximately 30,800 products and we shipped approximately 7.6 billion units in the first quarter of 2006 as compared to approximately 6.5 billion units in the first quarter of 2005. We specialize in micro packages, which offer increased performance characteristics while reducing the critical board space inside today’s ever shrinking electronic devices. We believe that our ability to offer a broad range of products provides our customers with single source purchasing on a cost-effective and timely basis.

Our reportable segments, under generally accepted accounting principles, are aligned internally as the Integrated Power Group and the Analog Products Group. In general, the power management and standard analog product line as well as the high frequency clock and data management product line are aligned under the Analog

35

Products Group, while the MOS power devices product line and the standard components product line are aligned under the Integrated Power Group. Our discussion of customers, trends and competitive conditions can generally be aligned accordingly. Our standard logic product unit, however, whose results are included in the Analog Products Group segment, is part of our standard components product line. The standard logic product unit had revenues of approximately $32.1 million and $22.1 million for the quarter ended March 31, 2006 and the quarter ended April 1, 2005, respectively. In instances where the characteristics of the standard components product line are significantly impacted by the standard logic product unit, these impacts are addressed separately herein.

We have approximately 170 direct customers worldwide, and we also service approximately 318 significant original equipment manufacturers indirectly through our distributor and electronic manufacturing service provider customers. Our direct and indirect customers include: (1) leading original equipment manufacturers in a broad variety of industries, such as Intel, Motorola, Nokia, Philips, Siemens and Sony; (2) electronic manufacturing service providers, such as Flextronics, Jabil and Solectron; and (3) global distributors, such as Arrow, Avnet, EBV Elektronik, Future, Solomon Enterprise and World Peace.

We currently have major design operations in Arizona, Rhode Island, Texas, China, the Czech Republic, Korea, and France, and we currently operate manufacturing facilities in Arizona, China, the Czech Republic, Japan, Malaysia, the Philippines, and Slovakia. We ceased manufacturing operations at our Rhode Island manufacturing facility in the second quarter of 2005 and exited the facility in the fourth quarter of 2005. The Rhode Island manufacturing facility is currently being marketed for sale. In the second quarter of 2005, we announced the transfer of wafer fabrication manufacturing operations from our front end fabrication facility in Malaysia to Arizona. We plan to complete this transfer by the first quarter of 2007 and to maintain the fabrication facility in Malaysia for other manufacturing processes. The transfer from Malaysia to Arizona did not impact our assembly and test operations in Malaysia. We also plan to sell certain unused portions of our property at our corporate headquarters in Arizona and use some of the proceeds from the sale to upgrade portions of our corporate headquarters. We will maintain our headquarters offices and existing manufacturing facilities on the portions of the property that are not for sale.

Effective April 5, 2006, we, through our principal domestic operating subsidiary, SCI LLC, entered into an asset purchase agreement with LSI Logic Corporation (“LSI”) to purchase LSI’s Gresham, Oregon wafer fabrication facility, including real property, tangible personal property, certain intellectual property, other specified manufacturing equipment and related information. The assets to be purchased include an approximately 83 acre campus with an estimated 500,000 square feet of building space of which approximately 98,000 square feet is clean room. Pursuant to the purchase agreement, we will offer employment to substantially all of LSI’s manufacturing employees currently working at the Gresham facility. At the closing of the transaction, we will enter into several ancillary agreements including, but not limited to, a wafer supply and test agreement, intellectual property license agreement, transition services agreement and facility use agreement. The aggregate purchase price for the acquired assets is approximately $105 million. The transaction is expected to close after the satisfaction or waiver of all conditions set forth in the purchase agreement. See “Key Financing Events—April 2006 Equity Offering” for further discussion.

Historically, the semiconductor industry has been highly cyclical. During a down cycle, unit demand and pricing have tended to fall in tandem, resulting in revenue declines. In response to such declines, manufacturers have shut down production capacity. When new applications or other factors have eventually caused demand to strengthen, production volumes have eventually stabilized and then grown again. As market unit demand has reached levels above capacity production capabilities, shortages have begun to occur, which typically has caused pricing power to swing back from customers to manufacturers, thus prompting further capacity expansion. Such expansion has typically resulted in overcapacity following a decrease in demand, which has triggered another similar cycle.

During the first quarter of 2006, we experienced a decrease in the end market unit demand and price decreases which resulted in decreased revenue compared to our previous quarter. However, we enjoyed growth in bookings during the first quarter with the book to bill ratio above one for the fourth consecutive quarter. We expect price declines during 2006 to be moderate and we will continue to monitor the supply and demand environment to determine if pricing could be held or increased.

Return to Profitability

In the third quarter of 2004 we returned to profitability after 14 consecutive quarters of net losses. We were profitable during each quarter of 2005 and during the first quarter of 2006 as well. Our net income for the quarter ended March 31, 2006, was $40.4 million. This return to profitability was the result of increased demand for our products in the market and cost savings from profitability enhancement programs and restructuring programs, as well as debt refinancing opportunities that have substantially reduced our interest costs.

Cost Savings and Restructuring Activities

Since the fourth quarter of 2000, we have been implementing profitability enhancement programs to improve our cost structure and, as a result, we expect to rank, as compared to our primary competitors, among the lowest in terms of cost structure.

Our 2004 profitability enhancement program includes the following:

• The phase out of our manufacturing operations in East Greenwich, Rhode Island, which was announced in December 2003, and our assembly and test operations in the Czech Republic, which was announced in November 2003. We began to realize the full benefit of savings from this program by the end of the fourth quarter of 2005, when the closure of our operations in East Greenwich was completed with all manufacturing equipment decommissioned and removed. During the fourth quarter of 2005, we successfully completed the work related to the decommissioning of the manufacturing building, which is currently being marketed for sale. We expect to incur marginal operating expenses in 2006 to maintain the building until the sale is completed. Overall, we expect the full cost savings from these activities will produce at least $20 million to $25 million of annual cost savings beginning in the first quarter of 2006.

• In the second quarter of 2004, we evaluated our operations in the Czech Republic and determined certain overhead functions were no longer necessary as a result of our previously announced transfer of our back-end manufacturing lines in Roznov to Malaysia and the Philippines. Following the reduction of such overhead functions, we realized approximately $7.7 million of actual cost savings in 2005.

• In the first quarter of 2004, we entered into a five-year agreement with respect to the outsourcing of information technology infrastructure. As part of the agreement, we sold certain system software modules, resulting in a loss on disposal of assets of $12.0 million. As a result of these actions, starting in the second quarter of 2004, we began to realize approximately $4.0 million of annualized cost savings that reduces our general and administrative expenses due to reduced depreciation expense.

More recently, in the second quarter of 2005, we announced our plan to transfer wafer fabrication operations from our facility in Malaysia to our facility in Arizona by the end of 2006, which will eliminate approximately 80 jobs. Due to the recently increased demand and increased backlog for products sourced out of the Malaysia and Arizona wafer fabrication operations, we expect to continue operating the wafer fabrication facility in Malaysia through the fourth quarter of 2006. As a result of the transfer of wafer fabrication operations from our facility in Malaysia to our facility in Arizona, we expect to realize costs savings of approximately $25.0 million to $30.0 million over the next five years, beginning by the end of 2006. Savings during 2006 are expected to be insignificant due to transition and other costs; however, savings during 2007 are expected to be approximately $7 million.

Although we have production at several locations, we have initiated process improvements and selective capital acquisitions that we expect will increase our overall capacity. Our profitability enhancement programs will continue to focus on:

• consolidation of manufacturing sites to improve economies of scale;

• transfer of production to lower cost regions;

• increase in die manufacturing capacity in a cost-effective manner by moving production from 4” to 6” wafers and increasing the number of die per square inch;

37

• reduction of the number of new product platforms and process flows; and

• focusing production on profitable product families.

New Product Innovation

As a result of the success of our research and development initiatives, excluding the introduction of lead-free products, we introduced 133 new products in 2005 and an additional 43 new products in the first quarter of 2006. Our new product development efforts continue to be focused on building solutions in power management that appeal to customers in focused market segments and across multiple high growth applications. It is our practice to regularly re-evaluate our research and development spending, to assess the deployment of resources and to review the funding of high growth technologies regularly. We deploy people and capital with the goal of maximizing our investment in research and development in order to position us for continued growth. As a result, we often invest opportunistically to refresh existing products in our commodity analog, standard component, MOS power and clock and data management products. We invest in these initiatives when we believe there is a strong customer demand or opportunities to innovate our current portfolio in high growth markets and applications.

Debt Reduction and Financing Activities

Since our 1999 recapitalization, we have had relatively high levels of long-term debt as compared to our principal competitors. During 2002 and 2003, we engaged in several debt refinancing transactions, which extended a portion of our debt maturities. Some of the transactions that extended our debt maturities also resulted in an increase in our overall interest expense and others lowered our overall interest expense. In connection with these transactions, we amended our senior bank facilities to, among other things, make our financial covenants less restrictive on the whole.

In the second half of 2005 we reduced our interest costs by issuing 1.875% convertible senior subordinated notes and using the proceeds from the issuance, along with cash on hand, to repay our junior subordinated note, which carried a significantly higher interest rate than the convertible senior subordinated notes. In November 2005, our outstanding Series A Cumulative Convertible Redeemable Preferred Stock beneficially owned by an affiliate of the Texas Pacific Group (“TPG”) was converted into common stock, which eliminated the accrual of preferred stock dividends. Additionally, in December 2004 and also in February 2006 we refinanced the term loans under our senior bank facilities to reduce the interest rate on the senior bank facilities.

In April 2006 we completed a public offering of 11.2 million shares (which includes 0.7 million shares issued as over-allotments) of our common stock issued approximately at a price of $7.00 per share. The net proceeds of $75.2 million from this offering will be used to partially fund the purchase of LSI’s Gresham, Oregon wafer fabrication facility, which has a total purchase price of $105 million.

The details of each of these financing events are outlined in the following sections. Also, see “Liquidity and Capital Resources” elsewhere in this report and Note 4 “Subsequent Events” and Note 8 “Common Stock” of the notes to our unaudited consolidated financial statements included elsewhere in this report.

Outlook

Not including any increased revenue associated with completing the purchase of the Gresham facility and based upon booking trends, backlog levels and estimated turns levels, we anticipate that revenues will be approximately $350 to $355 million in the second quarter of 2006 as compared to revenues of $302.8 million in the second quarter of 2005 and revenues of $334.0 million in the first quarter of 2006. Backlog levels at the beginning of the second quarter of 2006 were up from backlog levels at the beginning of the first quarter of 2006, and represent well over 90 percent of our anticipated second quarter 2006 revenues. We expect average selling

38

prices will be flat to slightly up sequentially in the second quarter of 2006. We also expect that gross margins will improve by between 50 to 100 basis points. Beginning in the first quarter of 2006, we are required to expense stock based compensation in accordance with the adoption of Statement of Financial Accounting Standards No. 123(R) “Share Based Payment”. We currently expect this expense to be approximately $2.5 million in the second quarter of 2006.

For the second quarter of 2006, we expect selling and marketing and general and administrative expenses at approximately 12% of revenues and research and development expenses at approximately 7% of revenues. We anticipate that net interest expense will be approximately $11.5 million for the second quarter of 2006. For the second quarter of 2006, and not including any impact associated with completing the purchase of the Gresham facility, we expect cash capital expenditures of approximately $35 million.

Revenues

Revenues were $334.0 million and $302.4 million during the quarter ended March 31, 2006 and the quarter ended April 1, 2005, respectively. The increase from the first quarter of 2005 to the first quarter of 2006 was primarily due to increased sales volume partially offset by a decrease in average selling prices by approximately 10.0%. As indicated in the table below, the increase was most pronounced in the standard components and MOS power devices product lines. Our average selling prices in the first quarter of 2006 relative to the fourth quarter of 2005 decreased by approximately 1.1%. The revenues by product line are as follows (dollars in millions):

	Quarter Ended March 31, 2006		As a % Revenue (1)		Quarter Ended April 1, 2005		As a % Revenue (1)		Dollar Change		% Change
Power Management and Standard Analog	$	101.3	30.3	%	$	92.2	30.5	%	$	9.1	9.9	%
MOS Power Devices		61.9	18.5	%		51.3	17.0	%		10.6	20.7	%
High Frequency Clock and Data Management		19.5	5.8	%		18.8	6.2	%		0.7	3.7	%

Total Revenues	$	334.0			$	302.4			$	31.6

(1) Certain amounts may not total due to the rounding of individual components.

(2) Revenues for the standard components product line includes $32.1 million and $22.1 million of revenues from the standard logic product unit for the quarters ended March 31, 2006 and April 1, 2005, respectively.

Revenues from our power management and standard analog product line increased $9.1 million, or 9.9%, in the first quarter of 2006 as compared to the first quarter of 2005. The increase can be attributed to an increase in revenues from the computing and consumer electronics end markets, partially offset by a decrease in revenues from the automotive electronics end markets.

Revenues from MOS power devices increased $10.6 million, or 20.7%, in the first quarter of 2006 as compared to the first quarter of 2005. The increase can be primarily attributed to an increase in revenues from the consumer electronics and wireless communications end markets, partially offset by a decrease in revenue from the computing end market and to the discontinuance of select products sold into the automotive electronics end markets.

Revenues from high frequency clock and data management products increased $0.7 million, or 3.7%, in the first quarter of 2006 as compared to the first quarter of 2005. The increase can be attributed to an increase in revenues from the networking and consumer electronics end markets, partially offset by a decrease in revenue from the industrial electronics end market.

Revenues from standard components increased $11.2 million, or 8.0%, in the first quarter of 2006 as compared to the first quarter of 2005. This product line consists of many products that are available from numerous competitors in the marketplace and is thus heavily influenced by pricing pressures and general market conditions. The increase in revenue can be primarily attributed to an increase in revenues from the wireless communications and computing end markets, partially offset by a decrease in revenue from the automotive electronics end market.

Revenues by geographic area as a percentage of revenues were as follows (dollars in millions):

	Quarter Ended March 31, 2006		As a % Revenue (1)		Quarter Ended April 1, 2005		As a % Revenue
Americas	$	77.2	23	%	$	79.3	26	%
Asia Pacific		201.7	60	%		166.4	55	%
Europe		55.1	16	%		56.7	19	%
Total	$	334.0	100	%	$	302.4	100	%

A majority of our end customers, served directly or through distribution channels, are manufacturers of electronic devices. In recent years, there has been a trend toward moving such manufacturing activities to lower cost regions, particularly in Asia. Our shift in revenues by geographic area reflects this trend.

Sales to our three largest customers accounted for approximately 11%, 10% and 9% of our revenue during the quarter ended March 31, 2006 and 11%, 9% and 8% during the quarter ended April 1, 2005. For the quarter ended March 31, 2006, approximately 60% of revenues from our largest three customers related to the Integrated Power Group and approximately 40% of revenues related to the Analog Products Group.

Approximately 17% of our revenues for the first quarter of 2006 are attributable to our various automotive customers. Certain of these automotive customers have been experiencing a downturn in their business, in part due to labor difficulties. On October 8, 2005, Delphi Corporation (“Delphi”), one of our automotive customers, and certain of Delphi’s U.S. subsidiaries commenced reorganization proceedings under Chapter 11 of the U.S. Federal Bankruptcy Code. During the quarter ended March 31, 2006, our revenues from Delphi accounted for less than 3% of our total annual revenues and approximately $5.4 million of our receivables due from Delphi as of March 31, 2006 are subject to collection pending resolution of the reorganization proceedings. We had reserved $1.6 million against our receivable from Delphi as of March 31, 2006.

Gross Profit

Our gross profit was $117.7 million in the first quarter of 2006 compared to $96.2 million in the first quarter of 2005. As a percentage of revenues, our gross profit was 35.2% in the first quarter of 2006 as compared to 31.8% in the first quarter of 2005. Gross profit increased during the first quarter of 2006 as compared to the first quarter of 2005 primarily due to cost savings from our 2004 profitability enhancement programs and increased sales volume, which were partially offset by declines in average selling prices.

Operating Expenses

Research and development expenses were $23.6 million in the first quarter of 2006 compared to $23.1 million in the first quarter of 2005, representing an increase of $0.5 million, or 2.2%. Research and development expenses represented 7.1% and 7.6% of revenues in the first quarter of 2006 and the first quarter of 2005, respectively. The $0.5 million increase in research and development is primarily attributable to increased headcount of our research and development personnel, an increase in employee performance bonuses as a result of our achievement of certain financial goals and increased stock compensation expense as a result of our adoption of Statement of Financial Accounting Standards No. 123R (“SFAS No. 123R”) during the first quarter of 2006, partially offset by the absence of software application costs associated with the implementation of cost management technology that occurred during the first quarter of 2005.

Selling and marketing expenses were $21.0 million in the first quarter of 2006 compared to $19.3 million in the first quarter of 2005, representing an increase of $1.7 million, or 8.8%. Selling and marketing expenses represented 6.3% and 6.4% of revenues in the first quarter of 2006 and the first quarter of 2005, respectively. The $1.7 million increase in selling and marketing expenses is primarily attributable to increased headcount of selling and marketing personnel primarily in our Asia Pacific locations due to our increased revenue concentration in this region, an increase in employee performance bonuses as a result of our achievement of certain financial goals and increased stock compensation expense as a result of our adoption of SFAS No. 123R during the first quarter of 2006.

General and administrative expenses were $20.2 million in the first quarter of 2006 compared to $20.4 million in the first quarter of 2005, representing a decrease of $0.2 million, or 1.0%. General and administrative expenses represented 6.0% and 6.7% of revenues in the first quarter of 2006 and the first quarter of 2005, respectively. The $0.2 million decrease in general and administrative expenses is primarily attributable to decreased costs for external services, including legal and consulting services, and decreased costs of information

41

technology outsourcing, partially offset by an increase in employee performance bonuses as a result of our achievement of certain financial goals and increased stock compensation expense as a result of our adoption of SFAS No. 123R during the first quarter of 2006.

Other Operating Expenses—Restructuring, Asset Impairments and Other, Net

There were no restructuring, asset impairments and other, net charges during the first quarter of 2006.

Restructuring, asset impairments and other, net were $1.1 million in the first quarter of 2005. During the first quarter of 2005, we recorded $1.3 million of employee separation charges and $0.3 million of cash exit costs related to the transfer of certain design center functions from Grenoble, France to Toulouse, France as well as $0.1 million of exit costs related to certain exit activities that were completed in connection with the shutdown of manufacturing operations in East Greenwich, Rhode Island that was announced in December 2003. These costs were offset by a gain on sale of land at East Greenwich of $0.5 million and the reversal of a $0.1 million reserve for cash exit costs related to the June 2002 restructuring activity that are no longer expected to be incurred.

For more information on our restructuring activity see Note 5 “Restructuring, Asset Impairments and Other, Net” of the notes to our unaudited consolidated financial statements included elsewhere in this Form 10-Q.

Interest Expense

Interest expense was $13.0 million in the first quarter of 2006 compared to $14.6 million in the first quarter of 2005. The decrease in interest expense was primarily a result of interest savings during the first quarter of 2006 that resulted from the repayment of the 10% junior subordinated note that occurred during the second half of 2005, which was partially financed with proceeds from the issuance of 1.875% convertible senior subordinated notes due 2025. Our average month-end long-term debt balance (including current maturities) in the first quarter of 2006 was $1,065.1 million with a weighted average interest rate of 4.9% compared to $1,148.8 million and a weighted average interest rate of 5.1% in the first quarter of 2005. See also “Liquidity and Capital Resources—Key Financing Events” for a description of our refinancing activities.

Provision for Income Taxes

Provision for income taxes was $2.0 million in the first quarter of 2006 compared to $1.8 million in the first quarter of 2005. The provision related to income and withholding taxes of certain of our foreign operations. Due to our continuing domestic tax losses and tax rate differentials in our foreign subsidiaries, our effective tax rate is lower than the U.S. statutory federal income tax rate.

Reportable Segments

As previously discussed, our reportable segments are aligned internally as the Integrated Power Group and the Analog Products Group. These segments represent our view of the company and inform how we evaluate the progress of its major components. Information about our reportable segments for the quarters ended March 31, 2006 and April 1, 2005 are as follows, in millions:

Liquidity and Capital Resources

This section includes a discussion and analysis of our cash requirements, our sources and uses of cash, our debt and debt covenants, and our management of cash.

Cash Requirements

Commercial Commitments, Contractual Obligations and Indemnities

Our principal outstanding contractual obligations relate to our long-term debt, operating leases, pension obligations and purchase obligations. The following table summarizes our contractual obligations at March 31, 2006 and the effect such obligations are expected to have on our liquidity and cash flow in the future (in millions):

(1) These represent our off-balance sheet obligations.

(2) Includes the interest portion of payments for capital lease obligations.

Our long-term debt includes $637.3 million under senior bank facilities amortizing through 2009 and potentially until 2011 under certain conditions, $260.0 million of zero coupon convertible senior subordinated notes due 2024, $95.0 million under our 1.875% convertible senior subordinated notes due 2025, $14.2 million

43

under a note payable to a Japanese bank amortizing through 2011, $14.0 million under a loan facility with a Chinese bank amortizing through 2007, $33.2 million under a loan facility with another Chinese bank amortizing through 2013 and $8.3 million of capital lease obligations. See Note 7 “Long-Term Debt” of the notes to our unaudited consolidated financial statements included elsewhere in this report.

In the normal course of our business, we enter into various operating leases for equipment including our mainframe computer system, desktop computers, communications, foundry equipment and service agreements relating to this equipment.

Our other long-term contractual obligations consist of estimated payments to fund liabilities that have been accrued in our consolidated balance sheet for our foreign pension plans. (See Note 6 “Balance Sheet Information” of the notes to our unaudited consolidated financial statements included elsewhere in this report.)

The table above does not include commitments under the asset purchase agreement to purchase LSI’s Gresham, Oregon wafer fabrication facility that we entered into effective April 5, 2006. The aggregate purchase price for the acquired assets is approximately $105 million. In connection with the execution of the purchase agreement, we paid LSI a deposit of $10.5 million. In addition, the purchase agreement obligates us to pay $79.5 million at the closing of the transaction and the remaining balance within 90 days thereafter. The transaction is expected to occur during May of 2006. To finance a portion of the purchase, we completed a public offering on April 6, 2006, of common stock registered pursuant to a shelf registration statement originally filed with the Securities and Exchange Commission on January 2, 2004. In connection with this offering, we issued approximately 11.2 million shares of our common stock at a price of $7.00 per share. The net proceeds from this offering were $75.2 million after deducting the underwriting discount of $1.6 million ($0.14 per share) and offering expenses of $1.3 million. See “Key Financing Events—April 2006 Equity Offering” for further discussion.

Our balance of cash and cash equivalents was $251.3 million at March 31, 2006. We believe that our cash flows from operations, coupled with existing cash and cash equivalents will be adequate to fund our operating and capital needs over the next 12 months. Our senior bank facilities include a $25.0 million revolving facility. Letters of credit totaling $11.4 million were outstanding under the revolving facility at March 31, 2006. We amended our primary foreign exchange hedging agreement to provide for termination if at any time the amount available under our revolving credit facility is less than $2.5 million.

Contingencies

We are a party to a variety of agreements entered into in the ordinary course of business pursuant to which we may be obligated to indemnify the other parties for certain liabilities that arise out of or relate to the subject matter of the agreements. Some of the agreements entered into by us require us to indemnify the other party against losses due to intellectual property infringement, property damage including environmental contamination, personal injury, failure to comply with applicable laws, our negligence or willful misconduct, or breach of representations and warranties and covenants related to such matters as title to sold assets.

We are a party to various agreements with Motorola, a former affiliate, which were entered into in connection with our separation from Motorola. Pursuant to these agreements, we have agreed to indemnify Motorola for losses due to, for example, breach of representations and warranties and covenants, damages arising from assumed liabilities or relating to allocated assets, and for specified environmental matters. Our obligations under these agreements may be limited in terms of time and/or amount and payment by us is conditioned on Motorola making a claim pursuant to the procedures specified in the particular contract, which procedures typically allow us to challenge Motorola’s claims.

We provide for indemnification of directors, officers and other persons in accordance with limited liability agreements, certificates of incorporation, by-laws, articles of association or similar organizational documents, as the case may be. We maintain directors’ and officers’ insurance, which should enable us to recover a portion of any future amounts paid.

44

In addition to the above, from time to time we provide standard representations and warranties to counterparties in contracts in connection with sales of our securities and the engagement of financial advisors and also provide indemnities that protect the counterparties to these contracts in the event they suffer damages as a result of a breach of such representations and warranties or in certain other circumstances relating to the sale of securities or their engagement by us.

While our future obligations under certain agreements may contain limitations on liability for indemnification, other agreements do not contain such limitations and under such agreements it is not possible to predict the maximum potential amount of future payments due to the conditional nature of our obligations and the unique facts and circumstances involved in each particular agreement. Historically, payments made by us under any of these indemnities have not had a material effect on our business, financial condition, results of operations or cash flows and we do not believe that any amounts that we may be required to pay under these indemnities in the future will be material to our business, financial condition, results of operations or cash flows.

See Part II, Item 1 “Legal Proceedings” of this report for possible contingencies related to legal matters and see Part I, Item 1 “Business—Government Regulation” of our annual report on Form 10-K for information on certain environmental matters.

Sources and Uses of Cash

We require cash to fund our operating expenses and working capital requirements, including outlays for research and development, to make capital expenditures, strategic acquisitions and investments, and to pay debt service, including principal and interest and capital lease payments. Our principal sources of liquidity are cash on hand, cash generated from operations and funds from external borrowings and equity issuances. In the near term, we expect to fund our primary cash requirements through cash generated from operations, cash and cash equivalents on hand and targeted asset sales. Additionally, as part of our business strategy, we review acquisition and divestiture opportunities and proposals on a regular basis.

We believe that the key factors that could affect our internal and external sources of cash include:

• factors that affect our results of operations and cash flows, including changes in demand for our products, competitive pricing pressures, effective management of our manufacturing capacity, our ability to achieve further reductions in operating expenses, the impact of our restructuring programs on our productivity and our ability to make the research and development expenditures required to remain competitive in our business; and

• factors that affect our access to bank financing and the debt and equity capital markets that could impair our ability to obtain needed financing on acceptable terms or to respond to business opportunities and developments as they arise, including interest rate fluctuations, our ability to maintain compliance with financial covenants under our existing credit facilities and other limitations imposed by our credit facilities or arising from our substantial leverage.

Our ability to service our long-term debt, to remain in compliance with the various covenants and restrictions contained in our credit agreements and to fund working capital, capital expenditures and business development efforts will depend on our ability to generate cash from operating activities which is subject to, among other things, our future operating performance as well as to general economic, financial, competitive, legislative, regulatory and other conditions, some of which may beyond our control.

If we fail to generate sufficient cash from operations, we may need to raise additional equity or borrow additional funds to achieve our longer term objectives. There can be no assurance that such equity or borrowings will be available or, if available, will be at rates or prices acceptable to us. We believe that cash flow from operating activities coupled with existing cash and cash equivalents will be adequate to fund our operating and capital needs as well as enable us to maintain compliance with our various debt agreements through March 31, 2007. To the extent that results or events differ from our financial projections or business plans, our liquidity may be adversely impacted.

45

Operations

Our operational cash flows are affected by the ability of our operations to generate cash, and our management of our assets and liabilities, including both working capital and long-term assets and liabilities. Each of these components is discussed herein:

EBITDA

Earnings before interest, taxes, depreciation and amortization (“EBITDA”) is a key indicator that management uses to evaluate our operating performance and cash flows. While EBITDA is not intended to represent cash flow from operations as defined by generally accepted accounting principles and should not be considered as an indicator of operating performance or an alternative to cash flow as a measure of liquidity, we believe this measure is useful to investors to assess our ability to meet our future debt service, capital expenditure and working capital requirements. This calculation may differ in method of calculation from similarly titled measures used by other companies. The following table sets forth our EBITDA for the quarters ended March 31, 2006, December 31, 2005, and April 1, 2005, with a reconciliation to cash flows from operations, the most directly comparable financial measure under generally accepted accounting principles (in millions):

	Quarter Ended

Net income	$	40.4		$	43.8		$	14.8

Changes in operating assets and liabilities		(17.8	)		(29.0	)		(9.2	)
Net cash provided by operating activities	$	50.5		$	46.2		$	36.2

Our debt covenants require us to maintain a trailing 12-month minimum adjusted EBITDA of $140.0 million. Adjusted EBITDA, as defined under the documents for our senior bank facilities totaled approximately $302.8 million for the 12 months ended March 31, 2006. This adjusted EBITDA computation excludes certain restructuring and other charges and contains other differences from the EBITDA as defined above. Therefore, EBITDA in the above table is not representative of the adjusted EBITDA used to determine our debt covenant compliance.

If we were not in compliance with the covenants contained in our senior secured credit agreement, including the adjusted EBITDA maintenance covenant, the holders of our senior secured indebtedness could cause all

46

outstanding amounts to be due and payable immediately. If we were unable to repay, refinance or restructure that indebtedness, the holders could proceed against the collateral securing that indebtedness. In addition, any such event of default or declaration of acceleration could also result in an event of default under one or more of our other debt instruments and have a material adverse effect on our financial condition, results of operations and liquidity.

Working Capital

Working capital fluctuates depending on end-market demand and our effective management of certain items such as receivables, inventory and payables. In times of escalating demand, our working capital requirements may increase as we purchase additional manufacturing inputs and increase production. Our working capital may also be affected by restructuring programs, which may require us to use cash for severance payments, asset transfers and contract termination costs. Our working capital, including cash, was $251.2 million at March 31, 2006, and has fluctuated between $211.9 million and $300.3 million over the last eight quarter-ends.

The components of our working capital at March 31, 2006 and December 31, 2005 are set forth below (in millions), followed by explanations for changes between December 31, 2005 and March 31, 2006 for cash and cash equivalents and any other changes greater than $5 million:

	March 31, 2006		December 31, 2005		Change

Other current assets		36.2		29.9		6.3
Deferred income taxes		4.4		7.4		(3.0	)
Total current assets		645.3		600.3		45.0

Current portion of long-term debt		52.3		73.9		(21.6	)
Total current liabilities		394.1		398.3		(4.2	)
Net working capital	$	251.2	$	202.0	$	49.2

The increase in cash and cash equivalents of $18.0 million in the first quarter of 2006 was attributable to cash flow from operations of approximately $50.5 million, partially offset by cash used in investing activities of $30.8 million, primarily as a result of payments for capital expenditures, and cash used in financing activities of $2.0 million which was attributable to primarily to debt repayments partially offset by proceeds received from stock option exercises.

The increase of $18.1 million in accounts receivable is the result of increased sales in the last two months of the first quarter of 2006 as compared to the last two months of the fourth quarter in 2005.

The increase of $5.6 million in inventory is attributable to production levels exceeding sales levels for the first quarter of 2006. Based on the outlook for the second quarter of 2006, we anticipate relatively flat inventory levels at the end of the second quarter of 2006.

47

The increase of $6.3 million in other current assets is primarily a result of a $2.3 million increase in tool and die and a $1.6 million prepayment for a software licensing agreement. The balance of the increase is related to increases in tax receivables and cash flow hedges as well as miscellaneous prepaid expenses.

The decrease of $5.2 million in accounts payable was mainly a result of the timing of payments at the respective period ends.

The increase in accrued expenses of $6.8 million was primarily attributable to a $5.2 million increase to sales related reserves due to the timing of payments, a $1.0 million increase in accrued payroll and a $1.0 million increase to other accruals, partially offset by a $0.4 million reduction to the restructuring reserves. Our restructuring reserve balance is $1.9 million and is expected to be paid by the end of the fourth quarter of 2006.

The increase in deferred income is attributable to increased inventory levels at distributors as compared to December 31, 2005 with inventories at distributors up from 9.8 weeks as of December 31, 2005 to 10.6 weeks as of March 31, 2006.

The decrease in the current portion of long-term debt relates to the timing of payments under our debt instruments including payments under the free cash flow provision of our senior bank facilities that were not required and were classified as long-term as of March 31, 2006. See Note 7 “Long-Term Debt” of the notes to our unaudited consolidated financial statements included elsewhere in this report.

Long-Term Assets and Liabilities

Our long-term assets consist primarily of property, plant and equipment, intangible assets, foreign tax receivables and capitalized debt issuance costs.

Our manufacturing rationalization plans have included efforts to utilize our existing manufacturing assets and supply arrangements more efficiently. Accordingly, we reduced our capital expenditures during 2005. We do not expect that our capital expenditure reductions will have a negative impact on our ability to service our customers, as we believe that near-term access to additional manufacturing capacity, should it be required, could be readily obtained on reasonable terms through manufacturing agreements with third parties. Capital expenditures were $31.7 million and $9.0 million during the quarter ended March 31, 2006 and the quarter ended April 1, 2005, respectively. We will continue to look for opportunities to make similar strategic purchases in the future as we plan to invest approximately $110 million in 2006 for additional capacity, excluding approximately $105 million for the purchase of LSI’s Gresham, Oregon wafer fabrication facility. Although our debt covenants contain certain restrictions that limit our amount of future capital expenditures, we do not believe that these restrictions will have a significant impact on our future operating performance.

Our long-term liabilities, excluding long-term debt, consist of liabilities under our foreign defined benefit pension plans and contingent tax reserves. In regard to our foreign defined benefit pension plans, generally, our annual funding of these obligations is equal to the minimum amount legally required in each jurisdiction in which the plans operate. This annual amount is dependent upon numerous actuarial assumptions.

Key Financing Events

Overview

Since we became an independent company as a result of our 1999 recapitalization, we have had relatively high levels of long-term debt as compared to our principal competitors. Our long-term debt includes significant amounts under our senior bank facilities, which contain an EBITDA (as defined for such facilities) covenant with which we were in compliance as of March 31, 2006.

48

During the second half of 2003, we began undertaking measures to reduce our long-term debt, reduce related interest costs and, in some cases, extend a portion of our debt maturities to continue to provide us additional operating flexibility. These measures continued into 2005 and 2006, as described below:

November 2005 Conversion of Redeemable Preferred Stock

On November 10, 2005, we entered into a Conversion and Termination Agreement with an affiliate of TPG to convert our outstanding convertible redeemable preferred stock held by such affiliate, with a book value of $138.7 million as of September 30, 2005, into 49,364,080 shares of our common stock. We issued an additional 3,949,126 shares of common stock to the TPG affiliate to induce the conversion of the preferred stock. Following the conversion, none of the authorized shares of the preferred stock remained outstanding. In connection with the conversion and inducement, we recognized a $20.4 million charge that reduced net income applicable to common stock for a deemed dividend from the issuance of inducement shares issued upon conversion.

December 2005 Repayment of 10% Junior Subordinated Notes and Issuance of 1.875% Convertible Senior Subordinated Notes

As part of the recapitalization, Semiconductor Components Industries, LLC (“SCI LLC”), our primary domestic operating subsidiary, issued a $91.0 million junior subordinated note due 2011. During periods it was outstanding, the note bore interest at an annual rate of 10.0%, compounded semi-annually and payable at maturity. The note was junior in right of payment to all senior debt. In November 2005, we repaid $66.4 million of the junior subordinated note with cash on hand, which reduced the outstanding principal amount to approximately $91.0 million.

In order to finance the repayment of the remaining principal amount of the junior subordinated note, in December 2005 we issued $95.0 million of 1.875% convertible senior subordinated notes due 2025. We received net proceeds of approximately $91.0 million from the sale of the notes after deducting commissions and estimated offering expenses of $4.0 million (of which $0.8 million remained unpaid as of March 31, 2006), which were capitalized as debt issuance costs and are being amortized using the effective interest method through the first put date of December 15, 2012. The notes bear interest at the rate of 1.875% per year from the date of issuance. Interest on the notes is payable on June 15 and December 15 of each year, beginning on June 15, 2006. The notes are fully and unconditionally guaranteed on an unsecured senior subordinated basis by certain of our existing and future subsidiaries.

The notes are convertible by holders into cash and shares of our common stock at a conversion rate of 142.8571 shares of common stock per $1,000 principal amount of notes (subject to adjustment in certain events), which is equivalent to an initial conversion price of approximately $7.00 per share of common stock. We will settle conversion of all notes validly tendered for conversion in cash and shares of our common stock, if applicable, subject to our right to pay the share amount in additional cash. Holders may convert their notes under the following circumstances: (i) during the five business-day period immediately following any five consecutive trading-day period in which the trading price per $1,000 principal amount of notes for each day of such period was less than 103% of the product of the closing sale price of our common stock and the conversion rate; (ii) upon occurrence of the specified transactions described in the indenture relating to the notes; or (iii) after June 15, 2012. As of March 31, 2006, none of these circumstances had occurred.

The notes will mature on December 15, 2025. Beginning December 20, 2012, we may redeem the notes, in whole or in part, for cash at a price of 100% of the principal amount plus accrued and unpaid interest to, but excluding, the redemption date. If a holder elects to convert its notes in connection with the occurrence of specified fundamental changes that occur prior to December 15, 2012, the holder will be entitled to receive, in addition to cash and shares of common stock equal to the conversion rate, an additional number of shares of common stock, in each case as described in the indenture. Holders may require us to repurchase the notes for cash on December 15 of

49

2012, 2015 and 2020 at a repurchase price equal to 100% of the principal amount of such notes, plus accrued and unpaid interest to but excluding the repurchase date. Upon the occurrence of certain corporate events, each holder may require us to purchase all or a portion of such holder’s notes for cash at a price equal to the principal amount of such notes, plus accrued and unpaid interest to but excluding, the repurchase date.

The notes are our unsecured obligations, will be subordinated in right of payment to all of our existing and future senior indebtedness, will rank pari passu in right of payment with all of our existing and future senior subordinated indebtedness and will be senior in right of payment to all our existing and future subordinated obligations. The notes also will be effectively subordinated to any of our and our subsidiaries’ secured indebtedness to the extent of the value of the assets securing such indebtedness.

February 2006 Amendment to Senior Bank Facilities

In February 2006, we refinanced the term loans under our senior bank facilities to reduce the interest rate from LIBOR plus 2.75% to LIBOR plus 2.50%. The amended and restated credit agreement also provided for a step down provision that reduced the interest rate to LIBOR plus 2.25% since we maintained a specified credit rating and meet the specified leverage ratio test that first applied based on the 2005 results.

March 2006 Amendment to Senior Bank Facilities

The credit agreement relating to our senior bank facilities includes a provision requiring an annual calculation of cash flow (as defined) and the application of a portion of that cash flow as a prepayment of loans outstanding under the agreement. In March 2006, we obtained an amendment of this provision that requires prepayment only at the election of the debt holders. As a result of this amendment, only $0.1 million of the $26.0 million classified as a current maturity as of December 31, 2005 was paid at the election of the debt holders during the first quarter of 2006. Therefore, the remaining $25.9 million was reclassified to long-term debt as of March 31, 2006.

April 2006 Equity Offering

On April 6, 2006, we completed a public offering of our common stock registered pursuant to a shelf registration statement originally filed with the Securities and Exchange Commission on January 2, 2004. In connection with this offering, we issued approximately 11.2 million shares (which includes 0.7 million shares issued as over-allotments) at a price of $7.00 per share. The net proceeds from this offering received by us were $75.2 million after deducting the underwriting discount of $1.6 million ($0.14 per share) and offering expenses of $1.3 million. We intend to use the net proceeds to partially fund the purchase of LSI’s Gresham, Oregon wafer fabrication facility, which has a total purchase price of $105 million.

Debt Instruments, Guarantees and Related Covenants

The following table presents the components of long-term debt as of March 31, 2006 and December 31, 2005 (dollars in millions):

	March 31, 2006			December 31, 2005

		1,062.0			1,067.0
Less: Current maturities		(52.3	)		(73.9	)
	$	1,009.7		$	993.1

We have pledged substantially all of our tangible and intangible assets and similar assets of each of our existing and subsequently acquired or organized domestic subsidiaries (but no more than 65% of the capital stock of foreign subsidiaries held by them) to secure our senior bank facilities.

SCI LLC, the primary domestic operating subsidiary of ON Semiconductor Corporation, is the borrower under our senior bank facilities. ON Semiconductor Corporation and our other domestic subsidiaries fully and unconditionally guarantee on a joint and several basis the obligations of the borrower under such facilities. ON Semiconductor Corporation is the issuer, and SCI LLC is a guarantor, of our zero coupon convertible senior subordinated notes due 2024 and our 1.875% convertible senior subordinated notes due 2025. Our other domestic subsidiaries fully and unconditionally guarantee on a joint and several basis the obligations of the issuers of such notes. None of our non-U.S. subsidiaries guarantee the senior bank facilities or the notes.

As of March 31, 2006, we were in compliance with the various covenants and other requirements contained in the credit agreement relating to our senior bank facilities and the indentures relating to our zero coupon convertible senior subordinated notes due 2024 and 1.875% convertible senior subordinated notes due 2025. We believe that we will be able to comply with the various covenants and other requirements contained in such credit agreement and the indentures through March 31, 2007.

The credit agreement relating to our senior bank facilities includes a provision requiring an annual calculation of cash flow (as defined) and the application of a portion of that cash flow as a prepayment of loans outstanding under the agreement. Included in the current portion of long-term debt as of December 31, 2005 was approximately $26.0 million, which is the amount that was expected to be paid during the first quarter of 2006 under this provision. As previously discussed, during the first quarter of 2006 we obtained an amendment of this provision that requires prepayment only at the election of the debt holders, and only $0.1 million was elected to be paid by the debt holders during the first quarter of 2006, so $25.9 million was reclassified to long-term liabilities as of March 31, 2006.

51

Our debt agreements contain, and any future debt agreements may include, a number of restrictive covenants that impose significant operating and financial restrictions on among other things, our ability to:

• incur additional debt, including guarantees;

• incur liens;

• sell or otherwise dispose of assets;

• make investments, loans or advances;

• make some acquisitions;

• engage in mergers or consolidations;

• make capital expenditures;

• pay dividends, redeem capital stock or make certain other restricted payments or investments;

• pay dividends from SCI LLC to ON Semiconductor Corporation;

• engage in sale and leaseback transactions;

• enter into new lines of business;

• issue some types of preferred stock; and

• enter into transactions with our affiliates.

In addition, our senior bank facilities require that we maintain or achieve a minimum consolidated adjusted EBITDA, as defined therein. Any future debt could contain financial and other covenants more restrictive than those that are currently applicable.

Cash Management

Our ability to manage cash is limited, as our primary cash inflows and outflows are dictated by the terms of our sales and supply agreements, contractual obligations, debt instruments and legal and regulatory requirements. While we have some flexibility with respect to the timing of capital equipment purchases, we must invest in capital on a timely basis to allow us to maintain our manufacturing efficiency and support our platforms of new products.

Accounting Changes

Effective December 31, 2005 we adopted FASB Interpretation No. 47 “Accounting for Conditional Asset Retirement Obligations—An Interpretation of FASB Statement No. 143” (“FIN 47”). FIN 47 clarifies that the term conditional asset retirement obligation as used in FASB Statement No. 143 “Accounting for Asset Retirement Obligations” (“Statement 143”) refers to a legal obligation to perform an asset retirement activity in which the timing and (or) method of settlement are conditional on a future event that may or may not be within the control of the entity. FIN 47 also clarifies when an entity would have sufficient information to reasonably estimate the fair value of an asset retirement obligation. As a result of the adoption of FIN 47, we recorded a $2.9 net charge for the cumulative effect of accounting change in 2005.

Effective January 1, 2006, we adopted SFAS No. 123R, which requires us to measure the cost of employee services received in exchange for an award of equity instruments based on the grant-date fair value of the award. That cost is recognized over the period during which an employee is required to provide service in exchange for the award. As a result of the adoption of SFAS No. 123R, our results of operations include $1.9 million of stock compensation expense during the quarter ended March 31, 2006.

52

Total estimated share-based compensation expense, related to all of our share-based awards, recognized for the quarter ended March 31, 2006 was comprised as follows (in millions, except per share data):

	Quarter Ended March 31, 2006
Cost of revenues	$	0.4
Research and development		0.3
Selling and marketing		0.5
General and administrative		0.7
Share-based compensation expense before income taxes		1.9
Related income tax benefits (1)		—
Share-based compensation expense, net of taxes	$	1.9
Net share-based compensation expense, per common share:
Basic	$	0.01
Diluted	$	0.01

(1) Most of our share-based compensation relates to its domestic subsidiaries which have historically experienced recurring net operating losses; therefore, no related income tax benefits are

expected.

We recorded $0.4 million in share-based compensation expense during the quarter ended March 31, 2006 related to share-based awards granted during the first quarter of 2006. This included expense related to the Employee Stock Purchase Plan of $0.2 million and an immaterial amount of expense related to restricted stock units awarded to certain members of our Board of Directors. The remaining expense of $1.5 million related to share-based awards granted prior to December 31, 2005.

Also, see “Results of Operations” elsewhere in this report and Note 3 “Significant Accounting Policies” and Note 9 “Employee Stock Benefit Plans” of the notes to our unaudited consolidated financial statements included elsewhere in this report.

Critical Accounting Policies and Estimates

The accompanying discussion and analysis of our financial condition and results of operations is based upon our audited consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America. We believe certain of our accounting policies are critical to understanding our financial position and results of operations. We utilize the following critical accounting policies in the preparation of our financial statements.

Revenue.    We generate revenue from sales of our semiconductor products to original equipment manufacturers, electronic manufacturing service providers and distributors. We recognize revenue on sales to original equipment manufacturers and electronic manufacturing service providers when title passes to the customer net of provisions for related sales returns and allowances. Title to products sold to distributors typically passes at the time of shipment by us so we record accounts receivable for the amount of the transaction, reduce our inventory for the products shipped and defer the related margin in our consolidated balance sheet. We recognize the related revenue and cost of revenues when the distributor informs us that they have resold the products to the end user. Although payment terms vary, most distributor agreements require payment within 30 days.

Sales returns and allowances are estimated based on historical experience. Given that our revenues consist of a high volume of relatively similar products, our actual returns and allowances do not fluctuate significantly from period to period, and our returns and allowances provisions have historically been reasonably accurate.

53

Freight and handling costs are included in cost of revenues and are recognized as period expense during the period in which they are incurred.

Inventories.    We carry our inventories at the lower of standard cost (which approximates actual cost on a first-in, first-out basis) or market and record provisions for slow moving inventories based upon a regular analysis of inventory on hand compared to historical and projected end user demand. Projected end user demand is generally based on sales during the prior 12 months. These provisions can influence our results from operations. For example, when demand falls for a given part, all or a portion of the related inventory is reserved, impacting our cost of revenues and gross profit. If demand recovers and the parts previously reserved are sold, we will generally recognize a higher than normal margin. However, the majority of product inventory that has been previously reserved is ultimately discarded. Although we do sell some products that have previously been written down, such sales have historically been relatively consistent on a quarterly basis and the related impact on our margins has not been material.

Deferred Tax Valuation Allowance.    We record a valuation allowance to reduce our deferred tax assets to the amount that is more likely than not to be realized. In determining the amount of the valuation allowance, we consider estimated future taxable income as well as feasible tax planning strategies in each taxing jurisdiction in which we operate. If we determine that we will not realize all or a portion of our remaining deferred tax assets, we will increase our valuation allowance with a charge to income tax expense. Conversely, if we determine that we will ultimately be able to utilize all or a portion of the deferred tax assets for which a valuation allowance has been provided, the related portion of the valuation allowance will be released to income as a credit to income tax expense. In the fourth quarter of 2001, a valuation allowance was established for our domestic deferred tax assets and a portion of our foreign deferred tax assets. Additionally, throughout 2003, 2004 and 2005 and continuing into 2006, no incremental domestic deferred tax benefits were recognized. Our ability to utilize our deferred tax assets and the continuing need for a related valuation allowance are monitored on an ongoing basis.

Impairment of Long-Lived Assets.    We evaluate the recoverability of the carrying amount of our property, plant and equipment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be fully recoverable. Impairment is assessed when the undiscounted expected cash flows derived for an asset are less than its carrying amount. Impairment losses are measured as the amount by which the carrying value of an asset exceeds its fair value and are recognized in operating results. We continually apply our best judgment when applying these impairment rules to determine the timing of the impairment test, the undiscounted cash flows used to assess impairments and the fair value of an impaired asset. The dynamic economic environment in which we operate and the resulting assumptions used to estimate future cash flows impact the outcome of our impairment tests. In recent years, most of our assets that have been impaired consist of assets that were ultimately abandoned, sold or otherwise disposed of due to cost reduction activities and the consolidation of our manufacturing facilities. In some instances, these assets have subsequently been sold for amounts higher than their impaired value. When material, these gains are recorded in the restructuring, asset impairment and other, net line item in our consolidated statement of operations and disclosed in the footnotes to the financial statements.

Goodwill.    We evaluate our goodwill for potential impairment on an annual basis or whenever events or circumstances indicate that an impairment may have occurred in accordance with the provisions of Statement of Financial Accounting Standards No. 142 “Goodwill and Other Intangible Assets” (“SFAS No. 142”), which requires that goodwill be tested for impairment using a two-step process. The first step of the goodwill impairment test, used to identify potential impairment, compares the estimated fair value of the reporting unit containing our goodwill with the related carrying amount. If the estimated fair value of the reporting unit exceeds its carrying amount, the reporting unit’s goodwill is not considered to be impaired and the second step is unnecessary. To date, our goodwill has not been considered to be impaired based on the results of this first step.

Defined Benefit Plans.    We maintain pension plans covering certain of our employees. For financial reporting purposes, net periodic pension costs are calculated based upon a number of actuarial assumptions, including a discount rate for plan obligations, assumed rate of return on pension plan assets and assumed rate of

54

compensation increase for plan employees. All of these assumptions are based upon management’s judgment, considering all known trends and uncertainties. Actual results that differ from these assumptions impact the expense recognition and cash funding requirements of our pension plans.

Asset Retirement Obligations.    We recognize asset retirement obligations (“AROs”) when incurred, with the initial measurement at fair value. These liabilities are accreted to full value over time through charges to income. In addition, asset retirement costs are capitalized as part of the related asset’s carrying value and are depreciated over the asset’s respective useful life. Our AROs consist primarily of estimated decontamination costs associated with manufacturing equipment and buildings.

Contingencies.    We are involved in a variety of legal matters that arise in the normal course of business. Based on the available information, we evaluate the relevant range and likelihood of potential outcomes. In accordance with SFAS No. 5, “Accounting for Contingencies”, we record the appropriate liability when the amount is deemed probable and estimable.

Share-Based Payments.    Prior to adopting the provisions of SFAS No. 123R, we recorded estimated compensation expense for employee stock options based upon their intrinsic value on the date of grant pursuant to Accounting Principles Board Opinion 25 (APB 25), “Accounting for Stock Issued to Employees” and provided the required pro forma disclosures of FASB Statement No. 123, “Accounting for Stock-Based Compensation” (“SFAS No. 123”). Because we established the exercise price based on the fair market value of the Company’s stock at the date of grant, the stock options had no intrinsic value upon grant, and therefore no estimated expense was recorded prior to adopting SFAS No. 123R.

We adopted the provisions of SFAS No. 123R on January 1, 2006, the first day of our fiscal year 2006, using a modified prospective application, which provides for certain changes to the method for recognizing share-based compensation. Under the modified prospective application, prior periods are not revised for comparative purposes. The provisions of SFAS No. 123R apply to new awards and to awards that are outstanding with future service periods on the effective date and subsequently modified or cancelled. Estimated compensation expense for awards outstanding with future service periods at the effective date will be recognized over the remaining service period using the compensation cost calculated for pro forma disclosure purposes under SFAS No. 123.

The fair value of each option grant in 2005 and thereafter is estimated on the date of grant using a lattice based option valuation model. In past years, we used the Black-Scholes option-pricing model to calculate the fair value of its options. The lattice model uses: 1) an implied volatility curve derived from Heston’s stochastic volatility model and calibrated using a regression analysis instead of a single volatility assumption as used in the Black-Scholes model; 2) an employee exercise behavior model (based on an analysis of historical exercise behavior); and 3) the treasury yield curve to calculate the fair value of each option grant. The estimates and assumptions used by management in conjunction with the lattice model significantly impact the resulting fair value of options granted.

At March 31, 2006, total unrecognized estimated compensation cost related to non-vested stock options granted prior to that date was $20.8 million, which is expected to be recognized over a weighted average period of 3.1 years.

On November 16, 2005, we accelerated the vesting of certain unvested and “out-of-the-money” stock options outstanding under the company’s stock plans. The acceleration of vesting applied to all unvested options that had an exercise price per share of $7.00 or higher, with the exception of options granted to directors, certain officers and employees with options granted under the French provisions in our 2000 Stock Incentive Plan. As a result of the acceleration, options to purchase approximately 2.5 million shares of our common stock became exercisable immediately. The weighted average exercise price of the affected options was $7.04 per share. In making the decision to accelerate these options, the Board of Directors believed it was in the best interest of the

55

stockholders to reduce the future earnings impact resulting from the planned adoption of SFAS 123R in the first quarter of 2006, and the resulting impact that this may have on our market value.

This acceleration of these options that were outstanding on November 16, 2005 will reduce future expenses upon the adoption of FAS 123R on a pre-tax basis as follows:

	Reduction in Non-cash Expense
	(millions)
2006	$	3.6
2007		3.6
2008		0.3
Total	$	7.5

Recent Accounting Pronouncements

In September 2005, the Emerging Issues Task Force reached consensus on EITF Issue No. 04-13, “Accounting for Purchases and Sales of Inventory with the Same Counterparty” (“Issue No. 04-13). In certain situations, a company may enter into nonmonetary transactions to sell inventory to another company in the same line of business from which it also purchases inventory. Under Issue No. 04-13, in general, an entity is required to treat sales and purchases of inventory between the entity and the same counterparty as one transaction for purposes of applying APB Opinion No. 29, “Accounting for Nonmonetary Transactions” when such transactions are entered into in contemplation of each other. When such transactions are legally contingent on each other, they are considered to have been entered into in contemplation of each other. The EITF also agreed on other factors that should be considered in determining whether transactions have been entered into in contemplation of each other. Issue No. 04-13 will be effective for all new arrangements entered into in reporting periods beginning after March 15, 2006. The Company’s adoption of the provisions of Issue No. 04-13 are not expected to impact its financial condition or results of operations.

In February of 2006, the FASB issued SFAS No. 155, “Accounting for Certain Hybrid Instruments—An Amendment of FASB Statements No. 133 and No. 144” (“SFAS No. 155”). SFAS No. 155 permits fair value remeasurement for any hybrid financial instrument that contains an embedded derivative that otherwise would require bifurcation. It also clarifies which interest-only strips and principal-only strips are not subject to the requirements of FASB Statement No. 133, and establishes a requirement to evaluate interests in securitized financial assets to identify interests that are freestanding derivatives or that are hybrid financial instruments that contain an embedded derivative requiring bifurcation. Furthermore, SFAS No. 155 clarifies that concentrations of credit risk in the form of subordination are not embedded derivatives and it amends FASB Statement No. 140 to eliminate the prohibition on a qualifying special purpose entity from holding a derivative financial instrument that pertains to a beneficial interest other than another derivative financial instrument. SFAS No. 155 is effective for all financial instruments acquired or issued after the beginning of the first fiscal year beginning after September 15, 2006. Our adoption of the provisions of SFAS No. 155 is not expected to impact our financial condition or results of operations.

Trends, Risks and Uncertainties

This Quarterly Report on Form 10-Q includes “forward-looking statements,” as that term is defined in Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. All statements, other than statements of historical facts, included or incorporated in this Form 10-Q are forward-looking statements, particularly statements about our plans, strategies and prospects under the heading “Management’s Discussion and Analysis of Financial Condition and Results of Operations”. Forward-looking statements are often characterized by the use of words such as “believes,” “estimates,” “expects,” “projects,” “may,” “will,” “intends,” “plans,” or “anticipates,” or by discussions of strategy, plans or intentions. In this Form 10-Q, forward-looking information relates to second quarter 2006 revenues, gross margins and average selling

56

prices, research and development expenses as a percentage of revenues, and sales and marketing and general and administrative expenses as a percentage of revenues, net interest expense, capital expenditures, and similar matters. All forward-looking statements in this Form 10-Q are made based on our current expectations and estimates, which involve risks, uncertainties and other factors that could cause results or events to differ materially from those expressed in forward-looking statements. Among these factors are our revenues and operating performance, changes in overall economic conditions, the cyclical nature of the semiconductor industry, changes in demand for our products, changes in inventories at our customers and distributors, technological and product development risks, availability of raw materials, competitors’ actions, pricing and gross profit pressures, loss of key customers, order cancellations or reduced bookings, changes in manufacturing yields, control of costs and expenses, significant litigation, risks associated with acquisitions and dispositions, risks associated with our substantial leverage and restrictive covenants in our debt agreements, risks associated with our international operations, the threat or occurrence of international armed conflict and terrorist activities both in the United States and internationally, risks and costs associated with increased and new regulation of corporate governance and disclosure standards (including pursuant to Section 404 of the Sarbanes-Oxley Act of 2002), and risks involving environmental or other governmental regulation. Additional factors that could affect our future results or events are described from time to time in our Securities and Exchange Commission reports. See in particular our Form 10-K for the fiscal year ended December 31, 2005 under Item 1A. “Risk Factors” and similar disclosures in subsequently filed reports with the Securities and Exchange Commission. Readers are cautioned not to place undue reliance on forward-looking statements. We assume no obligation to update such information.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

We are exposed to financial market risks, including changes in interest rates and foreign currency exchange rates. To mitigate these risks, we utilize derivative financial instruments. We do not use derivative financial instruments for speculative or trading purposes.

At March 31, 2006, our long-term debt (including current maturities) totaled $1,062.0 million. We have no interest rate exposure to rate changes on our fixed rate debt, which totaled $377.5 million. We do have interest rate exposure with respect to the $684.5 million outstanding balance on our variable interest rate debt; however, we have entered into interest rate swaps to reduce this exposure. As of March 31, 2006, we had interest rate swaps covering $292.5 million of our variable interest rate debt. A 50 basis point increase in interest rates would impact our expected annual interest expense for the next twelve months by approximately $2.0 million. However, some of this impact would be offset by additional interest earned on our cash and cash equivalents as a result of the higher rates.

On January 9, 2003, we amended our primary foreign exchange hedging agreement to provide for termination if at any time the amount available under our revolving credit facility becomes less than $2.5 million.

A majority of our revenue, expense and capital purchasing activities are transacted in U.S. dollars. However, as a multinational business, we also conduct certain of these activities through transactions denominated in a variety of other currencies. We use forward foreign currency contracts to hedge firm commitments and reduce our overall exposure to the effects of currency fluctuations on our results of operations and cash flows. Gains and losses on these foreign currency exposures would generally be offset by corresponding losses and gains on the related hedging instruments. This strategy reduces, but does not eliminate, the short-term impact of foreign currency exchange rate movements. For example, changes in exchange rates may affect the foreign currency sales price of our products and can lead to increases or decreases in sales volume to the extent that the sales price of comparable products of our competitors are less or more than the sales price of our products. Our policy prohibits speculation on financial instruments, trading in currencies for which there are no underlying exposures, or entering into trades for any currency to intentionally increase the underlying exposure.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures.    We carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of our disclosure controls and procedures (as defined in the Securities Exchange Act of 1934 (“Exchange Act”) Rules 13a-15(e) and 15d-15(e)). Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of the end of the period covered in this report, our disclosure controls and procedures were effective to ensure that information required to be disclosed in reports filed under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the required time periods and 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.

Change in Internal Control Over Financial Reporting.    There have been no changes in our internal control over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) that occurred during the fiscal quarter ended March 31, 2006 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II: OTHER INFORMATION

Item 1. Legal Proceedings

We are currently involved in a variety of legal matters that arise in the normal course of business. Based on information currently available, management does not believe that the ultimate resolution of these matters, including the matters described in the next paragraphs, will have a material adverse effect on our financial condition, results of operations or cash flows. However, because of the nature and inherent uncertainties of litigation, should the outcome of these actions be unfavorable, our business, financial condition, results of operations or cash flows could be materially and adversely affected.

During the period July 5, 2001 through July 27, 2001, we were named as a defendant in three shareholder class action lawsuits that were filed in federal court in New York City against us and certain of our former officers, current and former directors and the underwriters for our initial public offering. The lawsuits allege violations of the federal securities laws and have been docketed in the U.S. District Court for the Southern District of New York as: Abrams v. ON Semiconductor Corp., et al., C.A. No. 01-CV-6114; Breuer v. ON Semiconductor Corp., et al., C.A. No. 01-CV-6287; and Cohen v. ON Semiconductor Corp., et al., C.A. No. 01-CV-6942. On April 19, 2002, the plaintiffs filed a single consolidated amended complaint that supersedes the individual complaints originally filed. The amended complaint alleges, among other things, that the underwriters of our initial public offering improperly required their customers to pay the underwriters’ excessive commissions and to agree to buy additional shares of our common stock in the aftermarket as conditions of receiving shares in our initial public offering. The amended complaint further alleges that these supposed practices of the underwriters should have been disclosed in our initial public offering prospectus and registration statement. The amended complaint alleges violations of both the registration and antifraud provisions of the federal securities laws and seeks unspecified damages. We understand that various other plaintiffs have filed substantially similar class action cases against approximately 300 other publicly-traded companies and their public offering underwriters in New York City, which have all been transferred, along with the case against the Company, to a single federal district judge for purposes of coordinated case management. We believe that the claims against us are without merit and have defended, and intend to continue to defend, the litigation vigorously. The litigation process is inherently uncertain, however, and we cannot guarantee that the outcome of these claims will be favorable for us.

On July 15, 2002, together with the other issuer defendants, we filed a collective motion to dismiss the consolidated, amended complaints against the issuers on various legal grounds common to all or most of the issuer defendants. The underwriters also filed separate motions to dismiss the claims against them. In addition, the parties have stipulated to the voluntary dismissal without prejudice of our individual former officers and current and former directors who were named as defendants in our litigation, and they are no longer parties to the litigation. On February 19, 2003, the Court issued its ruling on the motions to dismiss filed by the underwriter and issuer defendants. In that ruling the Court granted in part and denied in part those motions. As to the claims brought against us under the antifraud provisions of the securities laws, the Court dismissed all of these claims with prejudice, and refused to allow plaintiffs the opportunity to re-plead these claims. As to the claims brought under the registration provisions of the securities laws, which do not require that intent to defraud be pleaded, the Court denied the motion to dismiss these claims as to us and as to substantially all of the other issuer defendants as well. The Court also denied the underwriter defendants’ motion to dismiss in all respects.

In June 2003, upon the determination of a special independent committee of our Board of Directors, we elected to participate in a proposed settlement with the plaintiffs in this litigation. If ultimately approved by the Court, this proposed settlement would result in the dismissal, with prejudice, of all claims in the litigation against us and against any of the other issuer defendants who elect to participate in the proposed settlement, together with the current or former officers and directors of participating issuers who were named as individual defendants. The proposed settlement does not provide for the resolution of any claims against the underwriter defendants, and the litigation against those defendants is continuing. The proposed settlement provides that the class members in the class action cases brought against the participating issuer defendants will be guaranteed a

59

recovery of $1 billion by the participating issuer defendants. If recoveries totaling less than $1 billion are obtained by the class members from the underwriter defendants, the class members will be entitled to recover the difference between $1 billion and the aggregate amount of those recoveries from the participating issuer defendants. If recoveries totaling $1 billion or more are obtained by the class members from the underwriter defendants, however, the monetary obligations to the class members under the proposed settlement will be satisfied. In addition, we and any other participating issuer defendants will be required to assign to the class members certain claims that we may have against the underwriters of our initial public offerings.

The proposed settlement contemplates that any amounts necessary to fund the settlement or settlement-related expenses would come from participating issuers’ directors and officers’ liability insurance policy proceeds, as opposed to funds of the participating issuer defendants themselves. A participating issuer defendant could be required to contribute to the costs of the settlement if that issuer’s insurance coverage were insufficient to pay that issuer’s allocable share of the settlement costs. We expect that our insurance proceeds will be sufficient for these purposes and that we will not otherwise be required to contribute to the proposed settlement.

Consummation of the proposed settlement is conditioned upon obtaining approval by the Court. On September 1, 2005, the Court preliminarily approved the proposed settlement and directed that notice of the terms of the proposed settlement be provided to class members. Thereafter, the Court held a fairness hearing on April 24, 2006, at which objections to the proposed settlement were heard. After the fairness hearing, the Court took under advisement whether to grant final approval to the proposed settlement.

If the proposed settlement described above is not consummated, we intend to continue to defend the litigation vigorously. While we can make no promises or guarantees as to the outcome of these proceedings, we believe that the final result of these actions will have no material effect on our consolidated financial condition, results of operations or cash flows.

AMS Matter.    On March 22, 2005, we entered into a settlement agreement with Austriamicrosystems, AG (“AMS”) regarding a pending lawsuit. Under the settlement agreement we paid AMS $2.4 million in cash upon the signing of the agreement. We had previously reserved $2.5 million as a reasonable loss estimate of the loss exposure for this matter. The settlement agreement includes, among other things, a full and complete mutual release of any and all claims, except for any claims arising out of the arbitration described below. It also provides that the pending litigation will be dismissed with prejudice and each party will bear its own costs and fees incurred in connection with the litigation. The dismissal occurred shortly after the signing of the agreement. The settlement agreement requires that we and AMS enter into final, binding and non-appealable arbitration limited to one unresolved issue associated with the litigation. The arbitration was held on April 12 through April 14, 2006 and we are currently awaiting a ruling by the arbitrator. If the arbitrator rules in favor of AMS, we will pay an additional $2.2 million within fifteen days of the ruling by the arbitrator. If the arbitrator rules in our favor, AMS will not be entitled to any additional amounts of money from us. On April 27, 2006, the arbitrator ruled in our favor. As a result of this ruling, AMS is entitled to no money from us regarding this issue. Each party shall bear its own costs and fees incurred in connection with the arbitration, and the parties will each pay fifty percent of the costs and fees of the arbitrator.

The matter originated out of an action filed in October 2003 in Arizona Superior Court by AMS against us. The complaint (i) alleged that we breached a foundry agreement entered into in 2000 under which AMS was to provide services to us, and (ii) claimed tortious interference with contract. The complaint sought approximately $5.8 million in contract damages, plus interest, costs, attorneys’ fees and exemplary damages.

Item 1A. Risk Factors

Our business, financial condition, operating results and cash flows can be impacted by a number of factors, including, but not limited to (i) those described under Item 1A “Risk Factors” in our Form 10-K for 2005 and (ii) those additional risk factors set forth below, any one of which could cause our actual results to vary materially from recent results or from our anticipated future results.

Trends, Risks and Uncertainties Related to the Acquisition of the Gresham Manufacturing Facility

If we fail to retain the highly-skilled personnel currently employed at the Gresham manufacturing facility, our ability to successfully integrate the facility and realize the benefits of the acquisition could deteriorate.

The success of the acquisition of the Gresham manufacturing facility depends upon our ability to retain the highly skilled technical, managerial and operations personnel currently employed at the facility. We expect to make offers of continued employment to many of these skilled process-development engineers and other employees with operational expertise. If these employees do not accept our offer of employment, we may be required to spend significant resources engaging employees with similar expertise or may be unable to secure such employees at all. The loss of services of these employees could prevent us from introducing the high-valued added products that can be manufactured on the Gresham manufacturing facility’s advanced technology platforms, mitigating the anticipated benefits of the acquisition.

In connection with the acquisition of the Gresham manufacturing facility, we will enter into a long-term supply contract with LSI, which may result in operating losses at the facility.

During the first two years following the consummation of the acquisition of the Gresham manufacturing facility, we will rely on LSI as the sole customer under a supply contract to meet minimum guaranteed revenue commitments. If we experience an increase in the cost of raw materials or lower than anticipated yields, or if we are unable to meet the cycle-time commitments called for by the contract, we may experience losses from operations at the facility.

We may experience difficulties in integrating and running the Gresham manufacturing facility.

Our ability to achieve the benefits we anticipate from the acquisition of the Gresham manufacturing facility will depend in large part upon whether we are able to integrate this facility into our business in an efficient and effective manner and once integrated actually running the facility in this manner. We may not be able to integrate this facility smoothly or successfully, and the process may take longer than expected. The integration of the manufacturing facility following its acquisition will require the dedication of significant management resources, which may distract management’s attention from our day-to-day business. We may encounter similar and additional difficulties as we continue to run the facility post-integration. If we are unable to integrate and run this facility successfully, we may be unable to realize the cost savings, revenue growth, gross margin improvement, earnings growth and other anticipated benefits we expect to achieve as a result of the acquisition and our business and results of operations could be adversely affected.

We may experience difficulties utilizing the additional capacity of the Gresham manufacturing facility in a cost-efficient manner.

After the expiration of our long-term supply contract with LSI, our ability to generate operating profits will depend upon our successful development of new products that can be produced using the technology of the Gresham manufacturing facility. Failure to successfully integrate new products into the Gresham manufacturing facility and failure to successfully market those new products could result in a loss of market share, or a lost opportunity to capitalize on emerging markets, and could have an adverse impact on our business and operating results.

The transition costs associated with the acquisition of the Gresham manufacturing facility may be greater than we anticipate.

In addition to the purchase price, we expect to incur significant one-time costs in connection with the acquisition of the Gresham manufacturing facility and the related integration of between $7.0 million and $12.0 million from 2006 to 2008. We also anticipate that the acquisition of the Gresham manufacturing facility will increase our fixed costs by between $90 million and $100 million annually. As a result, we expect that while our revenues will increase our gross margin percentage will be negatively impacted in 2006. The costs and liabilities actually incurred in connection with the acquisition and subsequent integration process may exceed

61

those anticipated. Although we expect that the realization of efficiencies related to the acquisition may offset additional expenses over time and result in net cost savings, we cannot ensure that this net benefit will be achieved soon or at all.

The projections that we used in valuing the Gresham manufacturing facility were based upon assumptions that we believed to be reasonable. However, these assumptions may prove to have been incomplete or inaccurate, and our projections could differ materially from actual operating results.
